BACKGROUND HISTORY
[0002] In the development of lock detent mechanisms which provide a movement in one direction and prevent movement in the opposite direction, Hendricks, U.S. Pat. No. 2,388,056, shows an adjustable stool or the like furniture article which can be moved in one direction and locked against movement in the other direction by means of a ball detent type construction. A release mechanism is provided. Aldridge also shows a detent lock mechanism of a general type in which there are a pair of sleeves with recesses on both sides for receiving a third member. The mechanism operates in one direction and locks in the opposite direction but can be released by a release spring.
[0003] Shiga, U.S. Pat. No. 5,549,011, discloses a three member structure providing inner and outer members which are recessed and provide locking in one direction and adjustment in the other direction for the third member which can be, by centrifugal force moved into a “fish hook” like pocket, so that movement in one direction can be made.
[0004] Stotler, U.S. Pat. No. 5,339,894, discloses a mechanism used in oil wells in which there are two sleeves and a third member such as a ball between the two sleeves. Pockets in each of the sleeves are provided for the ball and are designed so that movement of one sleeve in one direction will permit the ball to travel and lodge in the other sleeve and prevent the sleeves from movement when reversed direction is applied to the first movable sleeve. The primary difficulties with these various developments has been the failure of the locking member to properly fit into the lock mode causing damage or shifting of the sleeve members relative to each other or which requires manual manipulation which can be difficult at times requiring additional tooling to get it released in order to provide adjustment.
SUMMARY
[0005] When this fastener assembly either is serving directly as a product, or this fastener is combined with other components as a product, then after the installation thereof when a force is applied in one direction, this fastener assembly is self adjusting incrementally, as needed in travel or actuation; yet when a force is applied in the opposite direction, this fastener assembly is not self adjusting and there is no travel or actuation.
[0006] This fastener assembly, and respective embodiments, is arranged in cylindrical, arcuate, tubular and planar configurations. There are at least three members in each embodiment. There is a first member and a second member, which under a force of sufficient magnitude applied in one direction, will move relative to one another a preset distance, to await another force of sufficient magnitude of like direction to cause a like relative movement through another preset distance, thereafter repeating the sequences of relative movements in respect to respective designed embodiments, in this same one direction of the applied force. Yet, any force applied in the opposite direction, will not cause any essential opposite direction of the relative movement between the first member and second member.
[0007] This controlled one direction movement, centers on the utilization of the alternate positioning of a third member, called the locking member, which is controllably confined by both the first member and second member, when they are closely spaced apart in the assembled fastener assembly. During the preset locking positions, the locking member is partially received internally respectively in both the first member and the second member.
[0008] Any attempt to apply a force at this relative position of the first member and second member, in the opposite direction, is prevented, as this third member serves as the locking member, by being partially extending internally into both the first member and the second member. Yet when a wanted self adjusting force of sufficient magnitude is applied, the first member and second member are moved sufficiently, so the first member fully receives internally the locking member, which then has been moved clear of the second member.
[0009] The first member has a full receiving volume with a cam surface to guide and to fully receive the third member, then positioned out in the locking position. The second member has a partial receiving volume with a cam surface to guide and to partially receive the third member into the locking position.
[0010] In this embodiment of only the three members, the third member must be resilient enough to be either expanded or contracted from a pre-installed relaxed state, so when installed, the third member will always be attempting, via the stored energy thereof, to return to the locked position thereof, when partially extending internally into both the first member and the second member, to keep from moving, one relative to the other.
[0011] In some other embodiments, the third member is not resilient, such as a spherical locking member, an arcuate locking member, or a linear locking member. In these embodiments, when the third member is non-resilient, then a fourth member, having resiliency and sufficient stored energy, is needed to complete an embodiment of the particular fastener assembly, having at least four members. This fourth member will be positioned inside the first member in the locale of the full receiving volume thereof, to movably be always ready to direct the locking member, i.e. the third member, into the locking position thereof, when partially extending into both the respective volumes of the first member and second member.
[0012] In some other embodiments, when the third member is a resilient locking member, the first member is formed of two parts, which are movable relative to one another. Each of these two parts have both partial receiving volumes and partial cam surfaces. When the two parts are moved substantially apart, from a total locking configuration, clearance is provided to fully receive the third member, which via the stored energy thereof, moves fully into the clearance volume of this first member, formed of two parts. Then the first and second members may be moved relative to one another free of incremental stops. However, when the two parts are moved only a short distance part from a total locking configuration, relative movement in one direction is essentially prevented, and relative movement in the opposite direction is undertaken in incremental movements between locking positions.
[0013] In some other embodiments, when the third member is a resilient locking member, the second member is formed of two parts, which are movable relative to one another. One of these two parts has a partial receiving volume. When the two parts are moved directly together, in contact with one another, then the locking member is directed completely into the receiving volume of the first member, and the first member and the second member are relatively moved freely in either direction. When the two parts are moved apart a short distance, then relative movement soon permits the resilient third member to be positioned partially in both the first member and the second member having the two parts, locking these first and second members together, preventing relative movement in either direction. Then when the two parts of the second member are moved farther apart, then the relative movement in the one relative movement direction, soon permits the resilient third member to be moved completely into the receiving volume of the first part to permit an incremental movement until the next locking position is reached. Yet a relative movement in the opposite direction results in quickly reaching a locking position of the first and second parts, before any substantial incremental movements occurs.
OBJECTS OF THE INVENTION

A GENERAL DESCRIPTION OF THE EMBODIMENTS
[0043] The fastener assemblies illustrated in the figures of the drawings, have at least three members. When the third member is not resilient, then a fourth member which is resilient is included in the fastener assembly. These respective fastener assemblies, in their various embodiments, may themselves be a product or they may be combined with other members and assemblies to become another product, which in turn may be an end product, or yet may be installed with other members and assemblies to become another product.
[0044] The fastener assemblies are arranged in cylindrical, arcuate and planar embodiments, and the third member, also referred to as the locking component, is provided in many shapes in respect to the many embodiments of the fastener assembly.
[0045] Each embodiment of the fastener assembly has a first member, also referred to as a receiver component, which has a full receiving volume with a cam surface, to guide and to fully receive the third member. Also, each embodiment of the fastener assembly has a second member, also referred to as the engagement component, which has a partial receiving volume, with a cam surface to guide and to partially receive the third member.
[0046] The third member, serving as the locking component, either by resiliency thereof, or if not resilient, then by the resiliency of the fourth member, is always being directed into the locking position thereof. When the third member is in the locking position, the third member is located in both the partial receiving volume of the second member, and the full receiving volume of the first member.
[0047] When the third member is in this locking position, the respective volumes are so formed in their respective overall angular positions and contours, that the closely spaced first and second members, while confining the third member, i.e., the locking component, will not move under any applied force in one relative movement direction thereof. However, when they are moved in the other relative movement direction thereof, under a sufficient applied force, the first and second members will move, as the third member is temporarily moved by the action of the first and second members, to be entirely within the full receiving volume of the first member.
[0048] In a fastener completed as a product, or incorporated into other products, additional arrangements are made for additional receiving volumes, of either or both of the first and second members, and also in some embodiments, for additional third members, so the relative movements of the first and second members are incremental in the one direction. Yet at all times, any alternated movement of the first and second members in the opposite direction is not possible, unless, in a particular embodiment of the fastener assembly, the resilient member is positioned to be accessible in part, to receive an outside applied intentional force, which keeps the resiliency created return force from being effective in keeping the third member in the locking position thereof.
The Three Member Embodiment
[0049] The fastener assembly 10, in the three member embodiment 12, is illustrated in FIGS. 1 through 8 , to show a preferred arrangements of at least the minimal portions of at least three members, and how the respective relative movements thereof occur, during the sequences of their locking, in the presence of a relative force applied in one direction, and their incremental movement, in the presence of a relative force applied in the other direction. The assembly 10 may be color coded.
[0050] The first member 14 is oriented in some instance longitudinally axially and in others arcuately or circularly and, also called the receiver component 14, has a full receiving volume 16, with a cam surface 18, arranged on a bias, i.e., on an angle, so cam surface 18 is effective in guiding the movement of the third member 20 showing a center line C, also called the locking component, into and out of the full receiving volume 16. A third member 20 is circular-in-cross-section and may be a ball, ring or a roller or the like and must be in cross-section at least about 0.0005 inches less than the diameter and/or width of the first member 14 receiving volume 16. The receiving volume 16 is of “fish hook” configuration. The end of the “fish hook” is preferably a straight line tangent 21 parallel to surface 18 and ending in a point P.
[0051] The second member 22 which is oriented in some instances longitudinally axially and in others arcuately circularly and in a direction parallel to the first member, and also called the engagement component, has a partial receiving volume 24 of semi-teardrop shape, with a cam surface 26, arranged on a bias, i.e., on an angle, so the cam surface 26 is effective in guiding the movement of the third member into and out of the locking position, in conjunction with the cam surface 28 on the first member 14. First and second members 14 and 24 have parallel longitudinal axis and have complimentary volumes when positioned adjacent each other.
[0052] During the assembly of the first member 14 and the second member 22, the third member 20 circular in cross-section is confined by them. The first and second members each having a planar surface 28 and 30, which after assembly, are parallel to one another and slightly spaced apart. The respective entrances 32 and 34, of the receiving volumes 16 and 24 are located in these respective planar surfaces 28 and 30. The three members 14, 20 and 22 may be of different material such as plastic metal, etc. Some resiliency may be provided, but third member 20 should have only slight resiliency to avoid collapse under pressure. It is important that at least one of the first and second members 14 and 22 should have some malleability and that third member 20 should be of harder material. When member 20 is positioned in locked mode on members 14 and 22, member 20 causes indenting of at least the one of the members 14 and 22 thus increasing the contact area and load conveying ability of the assembly.
[0053] A portion 36 of the partial receiving volume 24 of the second member 22 is curved to complementary receive a curved portion of the third member 20, which preferably has a circular cross section 38.
[0054] In FIG. 1A , the locked position is illustrated of the fastener assembly 10. The third member, during the locking position, is positioned by this curved portion 36 and the cam surface 26 of the second member, and the cam surface 18 of the first member.
[0055] At this locked position time of the first and second members, the transverse distance A measured in the angular combined receiving volumes 16 and 24, and extending between the middle 36 of the curved portion 38 of the second member 22 and the cam surface 18 of the first member 14, is long enough to accommodate the circular cross section of the third member 20 having volume 40, i.e., the locking component 20. This transverse distance A is greater than the parallel transverse distance B, measured in the angular combined receiving volumes 16 and 24, and extending between the terminus 42 of the curved portion 38 at the planar surface 30 of the second member 22, and the cam surface of the first member 14. This parallel transverse distance B is not long enough to accommodate the circular cross section of the third member 20 having volume 40, i.e. the locking component 20, and therefore, the third member 20 is confined in the locking position thereof.
[0056] When the third member 20, i.e. the locking component, is in this locking position, the first and second members 14 and 22, will not essentially move relative to one another, in respect to one direction of their relative movement, regardless of the force applied, short of a fully destructive force. However, if a sufficient force is applied in the opposite relative direction, as indicated by the motion arrows in FIG. 1A , then the first and second member 14 and 22 will move relative to one another. When this wanted movement occurs, when a designed or specified sufficient force is applied, the respective cam surface 26 of the second member and the cam surface 18 of the first member are effective in directing the third member 20 into the full receiving volume 16 of the first member 14.
[0057] The restrictive transverse distance B is eliminated during this direction of the intended relative movement of the first and second members.
[0058] In FIG. 1A , the angle between the planar surface 28 of the first member 14 and the cam surface 18 of the first member 14 is preferably 45 degrees in a range of 10 degrees to 85 degrees. The angle between the planar surface 30 of the second member 22 and the cam surface 26 of the second member 22 is preferably 25 degrees, in a range of 10 degrees to 85 degrees. The selection of these respective selected angles, results in the positioning of the respective cam surfaces 18 and 26, so they effectively guide the third member 20 into and out of the locking position. The angular cam surfaces 18 and 26 continue until reaching the respective tangent locations 44 and 46, with a curved portion 36 of the partial receiving volume 24, and the preferably half circle portion 48 at the terminus of the full receiving volume 16.
[0059] As illustrated in FIG. 2 , the three members of the fastener assembly 10, in respect to this embodiment 12, are altered so the second member 22, the engagement component 22, has additional partial receiving volumes 24, spaced from one another. Therefore, the wanted relative directional movements are incremental between the times when the locking component 20, i.e. the third member 20, reaches another spaced locking position.
[0060] As illustrated by the phantom circular lines in FIG. 2 , if the third member 20 could expand freely again, this position would be reached. In this embodiment of three members, the third member 20 must be a resilient member, and always trying to move into the locking position when the third member 20, the locking component 20, is confined by both the receiving volumes 16 and 24, of the respective first and second members 14 and 22.
[0061] The incremental movement between two locking positions of this three member embodiment 12 of the fastener assembly 10 is illustrated in the respective sequences shown in FIGS. 3 through 8 . In FIG. 3 , the locking has occurred in respect to particular first partial receiving volume 24, and then the sequential movements are shown in FIGS. 4 , 5, 6, and 7, with FIG. 8 showing the nest locking occurring in respect to a second partial receiving volume 24, which then is cooperating with the full receiving volume 16 of the first member. It is necessary that the volume 16 is always in contact with a volume 24 during incremental movements. This allows for proper displacement while maintaining structural strength during earthquakes, etc.
[0062] In other embodiments, there are additional full receiving volumes 16 and additional third members 20, i.e. locking members 20, to meet different requirements and specification for different products in which the fastener assembly 10 is utilized.
The Utilization of the Fastener Assembly in the Construction of Wood Framed Buildings
[0063] The fastener assembly 10 arranged in the three member embodiment 12 illustrated in FIGS. 1 through 9 , and as described in reference to these figures, is further illustrated in another embodiment modification, which is cylindrical arranged and combined with other components to become a tie down system 50 for wood frame structures, as shown in FIGS. 9 through 14 .
[0064] In FIG. 9 , tie down 50 is shown, only in part, after the initial installation of an automatically adjusting assembly 52 centering on the utilization of the fastener assembly 10, arranged in a three member embodiment 12, arranged in an overall cylindrical form. In FIG. 10 , this portion, in respect to this assembly 52 of the tie down system 50, is shown after the expected life of automatic adjustments to compensate for the shrinkage and compression of the wood frame structural components.
[0065] This portion, in respect to this assembly 52, of the tie down system 50 is illustrated in FIG. 11 in use in a portion of a one story building 54 having wood frame structural components 56. This automatically adjusting assembly 52 is shown in FIG. 12 in use in a portion of a two story building 58 having wood frame structural components 56. Also this assembly 52 and another assembly 52 are illustrated in FIG. 13 in use in a portion of a three story building 60. Beside components 56, and extending therefrom at the top thereof, are reinforcing studs S extending from cross beam B downward to member 68 and engaging the surface thereof. Similarly reinforcing stud members S1 and S2 extend upwardly from the foundation 64 to member 68. In this manner, fastener assembly 10 is positioned between the cross beam B and foundation 64. Th studs S, S1 and S2 prevent lateral buckling of the shear wall components 56.
[0066] The automatically adjusting assembly 52, as particularly illustrated in FIGS. 9 and 10 , is positioned about a threaded tie rod 62, which is essentially continuous from a selected high starting position in a respective wood structure building 54, 58 or 60, down to an anchor coupling tie-in securement 63 such as a nut N with the concrete or the like foundation 64 of the respective building. The threaded tie rod 62, via this automatically adjusting assembly 52, which includes the fastener assembly 16, is automatically adjustably secured to a selected wood member, such as a transverse member called a plate or ceiling beam 66, and/or to another transverse wood member 68, specially positioned and interconnected with other wood frame structural components 56.
[0067] The threaded tie rod 62, via the original connections made and the subsequent adjustments to be automatically made with respect to the wood frame structural components 56, via the utilization of one or more of these automatically adjusting assemblies 52, is always ready to withstand any possible earthquake and/or wind forces that might occur, and thereby protect the building.
[0068] In FIG. 9 , the automatically adjusting assembly 52 is shown after the installation thereof, before any compression of the wood has occurred, and before the shrinkage of the wood has occurred because of the drying of the wood. At a location of a transverse wood member 68, a metal base member 70 of this automatically adjusting assembly 52 is secured to this transverse wood member 68. Previously, the second member 22, i.e. the engagement member 22, made of metal, has been secured to this metal base or plate 70. Plate 70 of metal is engaged by metal member 22 which rotates thereon thereby eliminating destructive torque on the wood member or beam 68. Also previously, the first member 14, made of metal, after the placement of two third members 20, each formed as an almost complete resilient metal locking ring or component 20, as illustrated in FIG. 14 , has been assembled with the second member, as shown in FIG. 9 .
[0069] The spaced full receiving volumes 16, of the first member 14, i.e. the receiving component 14, have received the respective two locking components 20, i.e. the two resilient third members 20. Also, the respective lower positioned spaced partial receiving volumes 24 of the second member 22, i.e. the engagement component 22, have also received a portion, or are about to receive a portion, of a respective resilient third member 20, i.e. a respective locking component 20.
[0070] This automatically adjusting assembly 52 also includes a nut 72 threadably secured to the threaded tie rod 62 and positioned a designed distance above the second member 22, i.e. the engagement component 22, to initially position a fully compressed coil spring 74 about the threaded tie rod 62, while this spring is axially confined between the nut 72 and the second member 22, i.e. the engagement member.
[0071] After the wood frame structural components 56 of a wood frame constructed building have been in place over a period of time, they move because of shrinkage and/or compression of the wood and other building materials. To compensate for this movement, the automatically adjusting assemblies 52 do adjust, as illustrated in FIG. 10 . The top located spaced partial receiving volumes 24 of the second member 22, i.e. the engagement member 22, are then serving to receive the third members 20, i.e. the locking component 20.
[0072] Then to compensate for the changing, now larger distance, between the nut 72 and the second member 22, i.e. the engagement member 22, the coiled spring 74 axially extends, yet the take up force created by the coiled spring 74 remains sufficient to keep the overall tie down system 50 firmly in place to quickly react to any possible occurring force caused by an earthquake and/or a wind force. It is to be noted in FIG. 13 that the fastener assemblies 10 in the multiple floor unit actuate independently of each other to take care of differential changes in each floor maintaining a firm tie down for each floor while operating on threaded tie rods 62 coupled in linear fashion by couples N.
Other Embodiments of the Fastener Assembly Arranged with Three Members
[0073] Other embodiments of the fastener assembly 10 centering on the cooperation of essentially the three members, i.e. the first member 14, also called the receiver component 14, the second member 22, also called the engagement 22, and the third member 20, also called the locking component 20, which in this three member embodiment must be a resilient third member 20, are illustrated essentially schematically in the respective partial sectional views of FIGS. 15 through 24 .
[0074] The first and second members 80 and 82, are formed in complementary arcuate portions, as illustrated in FIG. 15 . The first member 80 has a convex surface 84, interrupted by the full receiving volumes 86. The second member 82 has a concave surface 88, interrupted by the partial receiving volumes 90. The locking components 20, i.e. the third member 20, have a circular cross section.
[0075] In FIG. 16 , the first and second members 92 and 94 are also formed in complementary arcuate portions. However, the arcs are oppositely arranged. The first member 92 has a concave surface 96 interrupted by the full receiving volumes 98. The second member 94 has a concave surface 100 interrupted by the partial receiving volumes 102. The locking components 20, i.e. the third member 20, have a circular cross section.
[0076] The first member 104 is formed in two sections 106 and 108, which are movable relative to one another, to thereby change the configuration of the full receiving volume 110, as illustrated in FIGS. 17 through 20 . The second member 112 and the partial receiving volume 114 thereof remain similar in respect to other embodiments. The third member 20, the locking component 20, remains circular in cross section. In FIG. 17 , the locking component 20 is positioned ready to create a lock. In FIG. 18 , the locking position is shown. In FIG. 19 , the locking component 20 is not locking and is being carried in the full receiving volume 110. In FIG. 20 , the locking component 20 is being positioned to be quickly moved into the locking position thereof.
[0077] In FIGS. 21 through 24 , the second member 116, is shown formed in two sections 118 and 120, which are movable relative to one another, to thereby change the configuration of the partial receiving volume 122. The first member 124 and the full receiving volume 126 thereof remain similar in respect to other embodiments. The third member 20, the locking component 20, remains circular in cross section. In FIG. 21 , the locking component 20 is near the locking position thereof. In FIG. 22 , the locking component 20 is in the locking position. In FIGS. 23 and 24, the locking component 20 is fully positioned in the full receiving volume 126 and is thereby kept out of the locking position.
[0078] These schematic views in FIGS. 15 through 24 , indicate selected various embodiments of the fastener assembly 10, which have the three members, with the third member 20 being a resilient locking component 20.
An Assembly of Components which Include a Fastening Assembly of Three Members with the Second Member Having Two Sections, is Arranged to be a Quick Insert and Also a Reasonbly Quick Release Overall Fastener, to Join Together Respective Ends of Rods, Such as the Tie-Rods of a Hold Down System of a Wood Structure
[0079] The fastener assembly 10, in respect to the three member embodiments, has many applications where this fastener assembly 10 is combined with other assemblies, in turn serving many dynamic and/or statistic installations. In respect to one of these applications, illustrated in FIGS. 23 through 31 , where elongated members, such as threaded tie-rods 62, are to be joined end for end to thereby create a longer threaded tie-rods 62, the fastener assembly 10 is connection to a larger assembly of components 128 to create an overall connector 129. When using this overall connector 129, to join the threaded tie-rods 62 together, all the motion that is required is an in-line axial quick movement of the respective ends of the threaded tie-rods 62 together. There is no need to rotate any parts during these securement operations. Then when a release is wanted, only a nut is first turned through a few limited turns, and then a quick in line reverse axial movement of the respective ends of the threaded tie-rods 62 is undertaken to quickly separate the respective threaded tie-rods 62.
[0080] The first member 130, also called a female member 130, has a full receiving volume 16 positioning the resilient ring locking component 20, i.e. the resilient third member 20. A nut 132 is used to secure this first member 130 to the end of one of the threaded tie-rods 62, as illustrated in FIGS. 25 and 26 .
[0081] The male assembly 134 to be inserted into the female member 130, has a first nut 133 threaded on the other threaded tie-rods 62, followed by two sections 135 and 136, of the second member 138, and then followed by the second nut 140. As the two sections 135 and 136 are moved relative to one another, the partial receiving volume 142, they form, is changed, as illustrated in FIGS. 27 and 28 .
[0082] The respective threaded tie-rods 62, arranged with the respective female member 130 and the male assembly 134, are thereafter axially joined by using axially directed forces, and they are then locked together, as illustrated in FIGS. 29 and 30 .
[0083] If at a later time these threaded tie-rods 62 are to be separated, the first nut 133, also referred to as the jam nut 133, is turned sufficiently to move the sections 135 and 136 of the second member 138 together. When this occurs, the partial receiving volume 142 is eliminated sufficiently, so the locking component 20, i.e. the third member 20, is completely received in the full receiving volume 16 of the female member 130, i.e. the first member, as illustrated in FIGS. 31 and 32 . Then a quick release axial pull separates the threaded tie-rods 62.
A Fastener Assembly Having the Three Basic Members is Arranged so the Resilient Third Member May be Conveniently Manipulated From an Outside Location
[0084] When the fastener assembly 10 is arranged in three members and is joined with other components in some applications, there may be times when the fastener assembly 10 must be quickly released. An embodiment serving this need illustrated in FIGS. 33 , 34, and 35. The two alike locking components 144, serving as a resilient third members 144, have finger accessible portions 146, which extend through recesses 148 in the first member 14 and beyond into the open surrounding area to be finger manipulated. When the finger accessible portions 146 are moved, the locking portion of the third member 20 is temporarily eliminated. Thereafter, the first and second members 14 and 22 are axially quickly separated, also with whatever other components they are connected to, which are not illustrated.
A Fastener Assembly Having the Three Basic Members is Arranged in a Planar Assembly
[0085] In FIGS. 36 , 37 and 38, a fastener assembly 10 having the three basic members is arranged in a planar assembly 150. The second member 152 has a central-through-passageway 154, and the partial receiving volumes 156 are accessible from this passageway 154. The first member 158 is inserted in the second member 152 and has two full receiving curved volumes 160, which subsequently move relative to the partial receiving volumes 156, and the lengths of the first member 158 and the second member 152 are the same. The third members 162, i.e. the locking components 162 are resilient and bow upwardly under tension, and resiliently flex between both the full receiving curved volumes 160 and the multiple partial receiving volumes 156 during relative movement of first and second members 152 and 158.
A Fastener Assembly Having Four Basic Members Arranged with Other Members to Create, for Example, a Winch Type Gear System, the Fourth Member Being Required Because the Third Members are Not Resilient
[0086] As illustrated in FIGS. 39 and 40 , a fastener assembly 10 having at least four basic members, i.e. components, is arranged with other components to be a winch-type gear system 168. The fourth member becomes the resilient member which is used in positioning the non-resilient third member, which is the locking component.
[0087] The drive gear 170 transmits power to the driven gear 172, via components, which function as the components described previously as a fastener assembly 10, and are in effect a fastening assembly 174 or connecting assembly 174, positioned between the drive gear 170 and the driven gear 172. The drive gear 170 has at the end periphery thereof the first member 176, which has the full receiving volumes 178. The driven gear 172 has at the interior circular structure thereof, the second member 180, which has the many partial receiving volumes 182. A circular spring 184 is positioned, within a circular volume 186, provided in the first member 176, to be in constant resilient contact with the locking components 188, i.e. the third member 188, which are cylindrical in shape, and positioned within each full receiving volume 178.
[0088] During clockwise movement of the driving gear 170, the locking components 188 move to be occupying space in both the full receiving volumes 178 and the partial receiving volumes 182, and to thereby lock the drive gear to the driven gear. During the counterclockwise movement of the driving gear 170, the locking components 188 are moved periodically to be fully within the full receiving volumes 178, freeing the driven gear 172 from the driving gear 170, via incremental movements.
Another Fastener Having Four Basic Members Arranged with Other Members to Create, for Example, a Driving Spur Gear and a Larger Driven Gear System or Assembly, the Fourth Member Being Required Because the Third Members are Not Resilient
[0089] As illustrated in FIG. 41 , a fastener assembly 10, having at least four basic members, i.e. four basic components, is arranged with other components to be a driving spur gear and a larger driven gear system 192. The peripheral structure 194 of the driving spur gear 196 is formed to serve as the first member 198, i.e. the receiver component 198, having the full receiving volumes 200. The peripheral structure 202 of the large driven gear 204 is formed to serve as the second member 206, i.e. the engagement component 206, having the partial receiving volumes 208. The third member 210, the locking components 210, are cylindrical members which are not resilient. They are continuously being forced out of the full receiving volumes 200, by a circular spring 212, serving as the fourth resilient member, which is positioned in a receiving volume 214 of the driving spur gear 196. These third members 210 are constrained from leaving the full receiving volumes 200, by a non rotating circumferential guiding structure 216, also called a guiding race 216. This guiding structure 216 is not a complete encirclement, thereby leaving an open circumferential distance, so the third members 210 will be moved radially outwardly, under the force of the circular spring 212, i.e. the fourth member 212, to contact partial receiving volumes 208 of the larger driving gear 204.
[0090] During the clockwise rotation of the driving spur gear 196, the third members 210, in their cylindrical form of locking components 210 are moved, via the circular spring force, while guided by the cam surfaces of both the full and partial receiving volumes 200 and 208 to reach their respective sequential locking positions, thereby transmitting the driving power to the larger driven gear 204, to rotate this gear 204 in a counterclockwise direction.
[0091] During the possible counterclockwise rotation of the driven ring gear 196, the third members 210, are sequentially guided back into the full receiving volumes 200 against the force of circular spring 212, serving as the fourth member 212, and then there is essentially no clockwise rotation of the larger driven gear 204.
The Convenient Placement of an Embodiment on an Extended Threaded Tie Rod by Utilizing a First Member which is Made in Two Halves of Cylinder
[0092] As illustrated in FIGS. 42 through 47 , the fastener assembly 10 is provided in an embodiment 220 to facilitate the convenient placement, in less time, of this embodiment 220 at a selected location on an extended threaded tie-rod 62. The first member 222 is made of two alike cylinder halves 224 and 226. They have internal threaded 228 to mate with the external threads 230 of the threaded tie-rod 62. They have the full receiving volumes 232 to subsequently receive respective locking components 234, during the positioning of this embodiment 220 at the selected location along the threaded tie-rod 62.
[0093] As shown in FIG. 42 , the halves 224 and 226, first indicated by the phantom lines, are positioned independently, arriving from respective opposite directions, to be fitted or mated to the threaded tie-rod 62. Subsequently, respective split ring locking components 234 are axially directed over the mated 224 and 226 and positioned in the full receiving volumes 232. Then s illustrated in FIGS. 43 , 44, and 45, the second member 238, having partial receiving volumes 240, is axially directed to advance to the respective overlapping positions in the illustrated direction when axial relative movement is possible between the first member 222 and the second member 238. The split ring locking components 234 and the second member 238 are pre-positioned on the extended threaded tie-rod 62 before it is installed in a selected location, not shown.
[0094] In the fully overlapping position shown in FIG. 45 , which is the designated in-use position, the second member 238 of this embodiment is securable to a member, not shown, which is supported at this location along the threaded tie-rod 62, when this positioning is no longer required at this in-use position, then the axial movement of the second member 238 is continued as shown in FIGS. 46 and 47 . When the second member 2238 is cleared from the first member 222, the two alike cylindrical halves 224 and 226 are removed as indicated by the phantom lines FIG. 47 .
The Convenient Placement of an Embodiment of Any Extended Member Having a Circular Cross Section by Utilizing a Second Member which is Made with an Axially Directed Opening to Receive a Portion of the Extended Member
[0095] As illustrated in FIG. 48 , an embodiment 244 is provided, wherein the first member 246, having a smooth internal surface 248, and pre-fitted with locking components 234, received in full receiving volumes 232, along with other like sub assemblies 250, not shown, are placed about an extended member 252, having a circular cross section. At a selected location along the extended member 252 the sub assembly 250 is positioned on the extended member 252. Then the second member 254 having partial receiving volumes 240, and also having an axially directed opening 256, is moved to be positioned about the extended member 252. Thereafter, the second member 254 is moved axially for one way axial movement relative to the first member 246 to fully receive the first member 246. At this selected location, another selected part, not shown, is often secured to the second member 254 during the fabrication or manufacture of an overall product or assembly, not shown.
The Common Features and Common Objective Pertaining to All the Various Embodiments of the Fastener Assembly Serving as a Product Itself or Incorporated into Other Assemblies Serving as Products
[0096] Throughout the illustrated and non-illustrated embodiments of the direct utilization of the fastener assembly 10 as a product, or the incorporation of the fastener assembly 10 in other products, the objective are like or similar. Any sustained movement of a first member relative to a second member in one direction is essentially prevented, short of the unwanted forcible destruction of either or both the first and/or second member. Whereas, the relative movement in the other direction of the first member and the second member, caused by an intended force, is sequentially controlled, when there is an active force being provided by a resilient member.
[0097] In some embodiments, when a special force is selectively used to withdraw the otherwise active force provided by the resilient member, during the designed time, then the unrestricted movement of the first and second members in either relative direction is undertaken.
[0098] In some embodiments, the resilient members is the third member serving as the locking component. In other embodiments, the third member, serving as the blocking member, is not resilient and must be constantly directed to the locking position thereof, by the resilient force created by a fourth member.
[0099] In all embodiments, the first member has the full receiving volumes to fully receive, at sequential times, the third member serving as the locking component. In all embodiments, the second member has the partial receiving volumes to receive portions of the third member, when the locking positions of the first, second, and third member occur.
[0100] When the relative motion is attempted in one direction, the locking position of the first, second, and third members occurs quickly and remains to keep the first and second members from moving relative to one another. When the relative motion is undertaken in the opposite direction, the sequential periods of relative movements occur in reference to periods of forces being applied to move the first member relative to the second member.
[0101] While this invention has been described as having preferred design, it is understood that it is capable of further modification, uses and/or adaptations following in general the principle of the invention and including such departures from the present disclosure as come within known or customary practice in the art to which the invention pertains, and as may be applied to the essential features set forth, and fall within the scope of the invention or the limits of the appended claims.
