Two-Way Adjustable Tie

1. Field of the Invention

The present invention relates to ties, fasteners, straps, or belts and, in particular, to a two-way adjustable tie which can be used to tie garments, packages, cables, orthopedic devices, etc.

2. Background Information

Conventional embodiments of reusable ties commonly consist of ties made of plastic and ties made of velcro. Conventional reusable plastic ties include ties that are "adjustable" in one direction and "releasable" in the other direction. These conventional ties often contain a ratchet and pawl mechanism. The ratchet allows discrete adjustment (tightening) in one direction. The pawl allows continuous release (loosening) in the opposite direction. The pawl must be biased to release the strap and often wears out or breaks down after repeated usage. The pawl additionally may require excessive physical strength and/or dexterity to operate. Conventional art ties made of velcro do not have as strong a gripping capability and tend to further lose their grip after repeated usage or laundering. Additionally, velcro ties must be totally undone to be adjusted (tightened or loosened). The Two-Way Adjustable Tie of the present invention does not have the numerous disadvantages of conventional plastic and velcro ties described above.

The ties of the present invention have many benefits over conventional plastic ties including: (1) the ties of the present invention are readily adjustable and/or releasable in "both" directions; (2) the ties of the present invention have no moving parts to wear out or break down; and (3) the ties of the present invention require significantly less strength and/or dexterity to loosen or release the tie.

The Two-Way Adjustable Tie of the present invention can readily be adjusted (in either direction) by either moving (turning) the holder or pulling (toggling) the strap. The ties of the present invention have many advantages over velcro including: (1) the ties of the present invention do not wear out and lose their grip as velcro does; (2) the ties of the present invention can be adjusted, both tightened or loosened, while tied; and (3) the ties of the present invention are significantly stronger than velcro.

The nine embodiments of the present invention function similarly. They are locked when the strap and holder are in a fixed position relative to each other and unlocked (adjustable and/or releasable) when the strap and holder are not in this fixed position. Each of the nine embodiments loosen and tighten symmetrically. The same toggling, turning or pulling motion will either loosen or tighten the tie. The source of tension on the strap determines whether the tie will be loosened or tightened. Tension on the strap, in addition to either pulling (toggling) the strap or moving (turning) the holder causes the holder and strap to be out of alignment (unlocked), which permits the adjustment (loosening or tightening) of the tie. The embodiments shown are similar in function and utility, however, any given embodiment may prove easier to use, cheaper to manufacture, more durable and/or reliable, more suited for a given purpose or a specific demographic segment. In any of these embodiments, the movements to adjust the tie (loosen or tighten) are similar. First (to unlock), the strap can be pulled (toggled) or holder can be moved (turned). Second (to adjust), the strap is pulled in either direction, the directional source of "the pull" will determine whether the tie will be tightened or loosened. The disorientation of the strap to the holder created by the user, unlocks the tie thus permitting the strap to move through the holder in either direction for tightening or loosening. If the user does nothing, the tension on the strap automatically forces the strap to become perpendicularly oriented to the holder, and hence default to the locked position. In the sneaker illustrated in FIG. 3, for example, the "Two-Way Adjustable Tie" could advantageously be used instead of either laces or velcro. The holder and strap could be configured with tacks to fit into the lace holes. The sneaker with a tie of FIG. 6, for example, could be adjusted by pulling on the strap until the desired snugness is achieved. To unlock, the user simply turns the holders 90 degrees and slips out of the sneaker. The ties of the present invention have an advantage over laces because: (1) they do not loosen during wear; (2) they do not come undone; (3) they do not wear out or become dirty; and (4) they are easier to tie and adjust than laces (this is especially important for children and the elderly who might lack manual dexterity or strength).

The Two-Way Adjustable Tie of the present invention can be adjusted in either direction. While pulling the strap in either of the desired directions, the user may either: (1) pull (toggle) the strap as in FIGS. 5A-5E, 9A-9E, 13A-13E, 17A-17E, and 19A-19E; or (2) move (turn) the holder as in FIGS. 7A-7E, 11A-11E, 15A-15E, and 21A-21E.

An object of the present invention is for a tie which is inexpensive to manufacture, e.g., by being capable of being made of only one piece of plastic as illustrated in FIG. 1.

A further object is to produce a tie having no moving parts to wear out or break down, is durable and reliable, is adjustable in both directions, is releasable, reusable, and versatile.

Another object of the present invention is to produce a reusable tie which is both strong and readily adjustable.

It is a further object to produce a tie which can be tightened or loosened without untying (i.e., is readily adjustable), and a tie which can be released without destroying (i.e., is reusable).

Another object of the present invention is to create a tie of any length as illustrated in FIG. 2A. This both eliminates waste and the need to inventory different length ties. The strap could therefore be manufactured on a roll as shown in FIG. 2A, and be cut as needed to any desired length. These ties could use "double holders" as illustrated in FIG. 2B, which would be obtained separately.

Another object of the present invention is for a tie which can be configured to come in two parts, such as a strap and holder as illustrated in FIG. 3. The strap and holder are attached to the two sides of the item bound.

Another object of the present invention is for the inner surface of the strap to be generally flat, so as not to damage the contents it binds.

Another object of the present invention is for the strap to contain numerical indicia on the repeated projections so that the tie can be set to a fixed position and also be used to measure the girth of the contents it binds.

Another object of the present invention is for a tie which can be both tightened and loosened while requiring a minimum of physical strength or dexterity.

Another object of the present invention is for a tie which can be adjusted using only one hand.

Another object of the present invention is for a strap which is adjustable in discrete increments ranging from very small to very large.

The tie 10 of the present invention may be formed, for example, in any of the following three ways:

(1) As a one piece assembly as is shown by way of example in FIG. 1. The tie 10 includes a strap 12 whose one end is integrally connected to a holder 14 and whose other end is capable of being adjustably and releasably connected to the holder 14;

(2) As a two piece assembly having a variable length strap and a double holder as is shown by way of example in FIG. 2B. The double holder 14 holds both ends of the strap 12. Each end of the strap 12 has been cut to a desired length from the bulk strap material that can be conveniently mounted on a roll 16 as illustrated in FIG. 2A; or

(3) As a two piece assembly with each piece attached to the item being bound as is shown by way of example to a sneaker accessory in FIG. 3.

A first embodiment of the present invention is shown in FIGS. 4-5F. The one piece tie 110 includes a strap 112 and a holder 114. The strap 112 includes a first set of ratchet teeth 113 on its upper surface and a second set of ratchet teeth 115 on its lower surface. The holder 114 includes an upper inner surface 116 and a lower inner surface 118. The upper inner surface 116 is integrally connected to the lower inner surface 118 as a one piece assembly by connecting members 124.

The teeth 113 are shaped to mate with the teeth 120 so that the strap 112 will not move in the direction of arrow A, but allows ratcheting movement in the direction of arrow B. Similarly, the teeth 115 are shaped to mate with the teeth 122 so that the strap 112 will not move in the direction of arrow B, but allows movement in the direction of arrow A.

The upper inner surface 116 of the holder 114 includes approximately half of its surface being covered by ratchet teeth 120. The lower inner surface 118 also includes about half of its surface being covered by ratchet teeth 122. The ratchet teeth 120 are positioned on the opposite half of the surface being covered by the ratchet teeth 122. Also, the ratchet teeth 120 and 122 are arranged to ratchet in opposite yet parallel directions. The width of the ratchet teeth 120, 122 is slightly larger than the width of the ratchet teeth 113 on the strap 112.

FIG. 4A shows the holder with only one ratchet tooth on its upper and lower surface. A groove 125 shown in each tooth adds strength and flexibility to the ratchet tooth. Of course, any of the holders in any of the embodiments employing ratchet teeth could be formed with only one ratchet tooth on its upper and lower inner surface or with grooves or a pawl under the ratchet teeth to increase the holding force or elasticity of the teeth.

FIG. 5A shows the tie 110 in the locked position. The consecutive motions required between the holder 114 and the strap 112 to tighten and loosen the strap by one ratchet tooth are shown in FIGS. 5B-5F. From the locked position, strap 112 is moved with respect holder 114 in the direction of arrow C. That is, generally perpendicular to the direction of arrows A and B, with respect to the holder 114. Of course, the strap 112 could be held stationary and the holder 114 be moved in the direction opposite of arrow C, or a combination of both these two movements could be made. FIG. 5B shows the strap 112 and the holder 114 in the position where the strap 112 has been moved as far as possible in the direction of arrow C. Now, the user will pull strap 112 with respect to the holder 114 in the direction of arrow A by one or more ratchet teeth. FIG. 5C shows the strap 112 advanced by one tooth with respect to the holder 114. During this movement the user will feel the ratcheting effect as the strap 112 moves forward one tooth. In this process the strap 112 can be tightened. To loosen the strap 112 with respect to the holder 114, the user will simply move the strap 112 with respect to the holder 114 in the direction of arrow D, opposite of arrow C. FIG. 5D shows the strap 112 in the position where the strap 112 has been moved as far as possible in the direction of arrow D. Now the user will pull the strap 112 with respect to the holder 114 in the direction of arrow B, that is, the direction opposite that of arrow A. FIG. 5E shows the strap being moved one tooth from the position shown in FIG. 5D. In this way the strap 112 can be loosened to the desired length. Again the user can feel each tooth as the ratchet moves over them. After the strap 112 has been adjusted to the desired length, the strap 112 can be moved to the center position with respect to the holder 114 as shown in FIGS. 5A and 5F. Now, the strap 112 is in the locked position with respect to the holder 114 and the strap 112 cannot move in either direction A or B.

A second embodiment of the present invention is shown in FIGS. 6-7F. The two piece tie 210 includes a strap 212 and a holder 214. The strap 212 includes a first set of ratchet teeth 213 on its upper surface and a second set of ratchet teeth 215 on its lower surface. The holder 214 includes an upper inner surface 216 and a lower inner surface 218. The upper inner surface 216 is integrally connected to the lower inner surface 218 as a one piece assembly by connecting members 224.

The teeth 213 are shaped to mate with the teeth 220 so that the strap 212 will not move in the direction of arrow A, but allows ratcheting movement in the direction of arrow B. Similarly, the teeth 215 are shaped to mate with teeth 222 so that the strap 212 will not move in the direction of arrow B, but allows movement in the direction of arrow A.

A portion of the upper inner surface 216 of the holder 214 includes ratchet teeth 220. The lower inner surface 218 has an equivalent portion which includes ratchet teeth 222. The embodiment of the holder 214, illustrated in FIG. 6A, includes substantially the entire portion of the upper inner surface 216 having ratchet teeth 220 and substantially the entire lower inner surface 218 having ratchet teeth 222. In both embodiments, the ratchet teeth 220 and 222 are shown as being oriented at approximately 90 degrees from one another. The upper portion of the holder 214 is integrally connected to the lower portion of the holder by connecting members 224. The inner sides of the connecting members 224 are parallel and spaced at a distance slightly greater than the strap to guide the strap through the holder. The inner angle of the connecting members 224 is shown at approximately 90 degrees. However, if the ratchet teeth 220 and 222 are arranged at angles other than 90 degrees, such as, for example, 45 degrees, then the connecting members 224 would have an angle of 135.degree..

FIG. 7A shows the tie 210 in the locked position. The consecutive motions required between the holder 214 and the strap 212 to tighten and loosen the strap by one ratchet tooth are shown in FIGS. 7B-7F. As illustrated in FIG. 7B to tighten the strap 212 the user would first move the strap 212 with respect to the holder 214 in the direction of arrow A. As the strap 212 moves in the direction of arrow A the user will feel the strap 212 ratchet with respect to the holder 214. In FIG. 7C the strap 212 is shown with the strap being tightened by one tooth. Of course, the user can then continue to tighten the strap 212 by any number of teeth to the desired length. To loosen the strap 212 the user will first rotate the holder 214 in the counterclockwise direction as indicated by arrow C to the position shown in FIG. 7D. The user can now move the strap 212 in the direction of arrow B, opposite the direction of arrow A with respect to the holder 214. The user can then feel the strap ratchet with respect to the holder as the strap 212 moves over each tooth to be loosened. The strap 212 has been loosened by one tooth as illustrated in FIG. 7E. To allow continuous release of the strap in either direction the user turns the holder in the direction of D half way between 7E and 7F. In this orientation, the ratchets of the strap are not engaged with the ratchets in the holder and the strap may be moved continuously for tightening or loosening. To lock the holder, the user can then simply rotate the holder in the clockwise direction as illustrated by arrow D until the holder 214 is positioned as illustrated in FIG. 7F. In this position, the strap 212 cannot be loosened.

A third embodiment of the present invention is shown in FIGS. 8-9F. The one piece tie 310 includes a strap 312 and holder 314. The strap 312 includes a plurality of triangular-shaped projections 313. The projections 313 are alternately arranged on opposite sides of the strap 312. The holder 314 includes an upper inner surface 316 and a lower inner surface 318. The upper inner surface 316 is integrally connected to the lower inner surface as a one piece assembly by a pair of triangular-shaped connecting members 324.

FIG. 9A shows the tie 310 in the locked position. The consecutive motions required between the holder 314 and the strap 312 to tighten the strap are shown in FIGS. 9B-9F. FIG. 9A shows the strap 312 in a locked position with respect to the holder 314. To unlock the tie 310 for adjustment the user will first toggle the strap 312 in the clockwise direction B, with respect to the holder 314, as illustrated in FIG. 9C. After the strap moves to its furthest position in the clockwise direction B as shown in FIG. 9C, the user will then pull the strap 312 in the direction of arrow A to tighten (or in the direction opposite A to loosen) the strap 312. The strap 312 will then reach the position as shown in FIG. 9D. Now, the user can rotate the strap 312 with respect to the holder 314 in the counterclockwise direction of arrow C. The strap is then in the position as shown in FIG. 9E. In this position the strap 312 cannot be moved in the direction opposite of arrow A and it can only be advanced the distance of approximately one-half the length of the projection in the direction of arrow A as shown in FIG. 9F. In this manner, the strap 312 can be tightened.

A diameter of the bore 832 is sized to be slightly larger than a diameter of the cylindrical projection 813 of the strap 812.

FIG. 19A shows the tie 810 in the locked position. The consecutive motions required between the holder 814 and the strap 812 to tighten the strap are shown in FIGS. 19B-19E. First, the strap 812 is rotated in the clockwise direction as indicated by arrow A in FIG. 19B. After the strap 812 reaches the position illustrated in FIG. 19C, the strap 812 is moved into the paper such that the lower bottom surface of the strap 812 abuts the lower inner surface 818 of the holder such that the top of the projection 813 is below the planar surface of the upper inner surface 816. The tie is now unlocked and the strap may be adjusted (tightened or loosened) by one or more projections 813 in either direction. The strap 812 is then moved in the direction of arrow B as indicated in FIG. 19C. The strap 812 can now be moved by one or more projections 813. Next, to lock, the strap 812 slides above the beveled edge in the direction out of the paper FIG. 19D such that the lower bottom surface of the strap 812 is above the upper surface of the beveled portions 826 of the connecting members 824 and such that one of the cylindrical projections 813 is within the bore 832 of the holder 814. The strap 812, as illustrated in FIG. 19E, has now been tightened by one projection with respect to the holder 814.

The ninth embodiment of the present invention is shown in FIGS. 20-21E. The tie 910 includes a strap 912 and a holder 914. The strap 912 includes a plurality of semicircular projections 913. The semicircular projections 913 are located in pairs diametrically opposite one another and axially spaced along the strap 912. The holder 914 is a cylindrically-shaped hollow member having a first axial end 916 and a second axial end 918. Each axial end 916 and 918 includes a central axial bore 920 whose diameter is slightly larger than the diameter of the strap 912. The first axial end 916 also includes a rectangular-shaped radial slot 922 whose radial dimension is slightly larger than the radial dimension of the semicircular projections 913. The second axial end 918 also includes a rectangular-shaped radial slot 924 whose radial dimension is slightly larger than the radial dimension of the semicircular projections 913. The slot 922 is substantially perpendicular to the slot 924. A pair of rectangular bar-shaped members 926 and 928 are also within the holder 914. The bar-shaped members 926 and 928 are placed parallel to the central axis of the holder 914 and are located diametrically opposite one another.

FIG. 21A shows the tie 910 in the locked position. The consecutive motions required between the holder 914 and the strap 912 to tighten the strap are shown in FIGS. 21B-21E. First, the holder 914 is rotated with respect to the strap 912 in the direction indicated by the arrow A until the semicircular projections 913 are stopped by the bar-shaped members 926 and 928 within the holder 914. Next, the strap 912 is pulled in the direction of the arrow B as shown in FIG. 21B. The semicircular projections 913 will now pass through the rectangular slot 922 in the first axial end 916 of the holder 914. Once the strap 912 has reached the position indicated in FIG. 21C, the holder 914 is rotated in the reverse direction with respect to the strap 912 by approximately 90 degrees. The semicircular projections 913 now line up with the rectangular slot 924 in the second axial end face 918 of the holder 914. The strap 912 can now be pulled along the direction of arrow B as indicated in FIG. 21D until the semicircular projections 913 are once again within the holder 914 as shown in FIG. 21E. The strap 912 has now been tightened with respect to the holder 914 by one projection. To further tighten the strap 912 with respect to the holder 914, the aforementioned steps are to be followed. To loosen the strap 912 with respect to the holder 914 the pull is from the direction opposite to B.

While this invention has been described in connection with what is presently considered to be the most practical and preferred embodiment, it is to be understood that the invention is not limited to the disclosed embodiment, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
