Twisting exercise apparatus

[0002] This invention relates to a twisting exercise apparatus which has an upright structure that allows the user to perform twisting exercise routines while in a sitting position. This feature allows for a better upper and lower body workout than provided by more conventional upper and lower body combination exercise devices.

[0003] It is the object of this invention to provide an exercise apparatus which may provide the user a well balanced upper and lower body combination exercise routine. The main purpose of this application is to demonstrate an apparatus which performs the stated function, and to demonstrate the many options and configurations this apparatus may take on.

[0004] Briefly stated, the apparatus that forms the basis of the present invention comprises a frame means, a seat support means, a hand engagement means, and a power transfer means. The seat support means, hand engagement means, and the power transfer means are all mounted upon the frame means. Optional items include a back support means and thigh engagement means associated with the seat support means. Also, an optional resistance means may be supported by the frame means, and operatively connect the hand engagement means and the seat support means.

[0005] The design of the apparatus is such that the hand engagement means is moveable in the forward and backward directions with respect to the frame means. This movement causes the seat support means to twist or pivot in the clockwise and counter-clockwise directions. Conversely, pivoting motion in the seat support means produces forward and backward motion in the hand engagement means. This provides the user an exercise routine for many of the upper and lower body muscle groups. Other objects, features, and advantages for this invention will be apparent from the following detailed description and the appended claims, references being made to the accompanying drawings forming a part of the specification, wherein like reference numerals designate corresponding parts of the several views.

[0033] Before explaining in detail the present invention, it is to be understood that the invention is not limited in its application to the details of construction or arrangement of parts illustrated in the accompanying drawings, since the invention is capable of other embodiments and of being practiced or carried out in various ways. Also, it is to be understood that the phraseology and terminology employed herein is for the purpose of description, and not limitation.

[0034] As best can be seen by references to the drawings, and in particular to FIGS. 1A-1C, the twisting exercise apparatus that forms the basis of the present invention is designated generally by the reference numeral 10, and includes a frame means 11, a seat support means 12, a hand engagement means 13, and a power transfer means 14. The seat support means 12, hand engagement means 13, and the power transfer means 14 are all mounted on frame means 11.

[0035] As may be seen in FIGS. 2A-2C, the frame means 11 comprises a base 20, a seat mount 21, a power transfer mount 22, and handle mounts 23. The seat mount 21 is used to support seat support means 12, while the handle mounts 23 are used to support hand engagement means 13. Power transfer mount 22 is used to support the power transfer means 14.

[0036] As may also be seen in FIGS. 3A-3C, the seat support means 12 comprises a seat 30 and a seat support member 31. Seat support member 31 is used to support seat 30.

[0037] As may be seen in FIGS. 4A-4C, the hand engagement means is comprised of two handle members 40. Each handle member 40 includes a base mount opening 41 and a power transfer connector 42.

[0038] FIGS. 5A-7C demonstrate the various components of the power transfer means 14. FIGS. 5A-5C demonstrate a handle connector 50 having a handle mount opening 51 and a lever connector 52. The power transfer means 14 has two handle connectors 50, one for each handle member 40. FIGS. 6A-6C demonstrate a lever member 61 having adaptably adjustable lever end segments 62. Each end segment 62 has a lever end segment opening 65. Also shown is lever support member 63 and lever rotatable member 64. FIGS. 7A-7C demonstrate the seat rotatable member 71 having a seat rotatable member opening 72.

[0039] As may be seen in FIGS. 1A-1C, and FIG. 8A, the handle members 40 of hand engagement means 13 are pivotally mounted to handle mounts 23 of frame means 11, and extend in a generally upward direction from said frame means 11. Seat support member 31 of seat support means 12 is pivotally mounted to seat mount 21 of frame means 11, and also extends in a generally upward direction from said frame means 11. Seat 30 is rigidly mounted to seat support member 31. Also, seat rotatable member 71 of power transfer means 14 is rigidly mounted to seat support member 31 through seat rotatable member opening 72. Lever support member 63 of power transfer means 14 is pivotally mounted to power transfer mount 22 of frame means 11, and extends in a generally upward direction from said frame means. Both lever member 61 and lever rotatable member 64 are rigidly mounted to lever support member 63, at a generally perpendicular angle. Lever member 61 has lever end segments 62 loosely mounted within, such that they may move in the inward and outward directions, and also rotate within lever member 61. Each handle connector 50 of power transfer means 14 pivotally connects to a handle member 40 of hand engagement means 13 through power transfer connector 42. The other end of handle connector 50 has a lever connector 52 which pivotally connects to lever end segment 62 through lever end segment opening 65. A closed loop connection means 80 connects lever rotatable member 64 and seat rotatable member 71.

[0040] The operation of the twisting exercise apparatus may be seen in FIGS. 9A-9B. Handle members 40 are mounted on opposite sides of the frame means 11, and move in the forward and backward directions, opposite one another. As the handle members 40 move, forward and backward motion is produced in lever member 61, and a backward and forward pivoting motion is produced in lever rotatable member 64. Lever rotatable member 64 produces a similar pivoting motion in seat rotatable member 71, since they are connected together by a closed loop connection means 80. The motion in seat rotatable member 71 causes the seat 30 to pivot backward and forward. Thus, movement of the handle members 40 causes pivoting motion in seat 30. The reverse is also true. Pivoting motion in the seat 30 will produce forward and backward motion of the handle members 40. Lever member 31 produces the alternating movement of the handle members 40. The preferred operation of the apparatus is that forward movement of the right side handle member 40 corresponds to counter-clockwise pivoting movement of the seat 30, and forward movement of the left side handle member 40 corresponds to clockwise pivoting movement of seat 30.

[0041] FIGS. 8B and 8C demonstrate other possible configurations for the transfer of motion between the handle members 40 and the seat member 30. FIG. 8B demonstrates a gear assembly configuration in which both lever rotatable member 64 and seat rotatable member 71 are gears with interfacing teeth. FIG. 8C demonstrates how lever member 61 may mount directly to seat support member 31. The preferred embodiment is the closed loop connection configuration shown in FIG. 8A, which may be a chain and sprocket assembly. Compared to the direct mounting of the lever member 61 and the seat support member 31, this configuration will produced a larger pivoting motion in the seat 30, with less movement of the handle members 40, provided seat support member 31 is smaller than lever rotatable member 64. This would also be true of the gear assembly configuration. Many other variations of the power transfer means exist which will perform the same indicated function.

[0042] FIGS. 10A and 10B demonstrate optional items which may be added to the seat support means 12 to improve the device. Back support member 100 may be added to make the device more comfortable. Outer thigh engagement members 101 and 103, and inner thigh engagement member 102 provide the user more operational features. The user may press their thighs against these members to enhance their workout routines. The thigh engagement members described above may be used to both produce and resist movement of the seat. Since the thigh engagement members are rigidly mounted to the seat, the user may press against one or more of these members with the general thigh area of their leg, thus causing the seat to pivot. Conversely, when movement of the seat is produced by engaging the handle members, the user may press against one or more of the thigh engagement members with the general thigh area of the leg, resisting movement of the seat.

[0043] FIG. 11 demonstrates a resistance means 110 which may be part of the apparatus. It may connect to the power transfer means 14 through a closed loop connection means 81 as shown, be part of a gear assembly, or be some other commonly known connection. The resistance means may be any type of commonly known resistance component, such as a flywheel with a tension belt, a magnetic resistance component, an electromagnetic component, etc.

[0044] The resistance means mentioned above is considered optional because it is possible for the user to utilize their own muscles for resistance. For example, the user may push and pull on the handle members, and use their body muscles to resist movement of the seat, thus providing resistance to the movement of the handle members. The reverse is also true in that the user may produce the pivoting motion of the seat, and use their body muscles to resist movement of the handle members, which provides resistance to seat movement.

[0045] Many variations of the twisting exercise apparatus exist, along with the configurations described above. While it will be apparent that the preferred embodiment of the invention herein disclosed is well calculated to fulfill the objects above stated, it will be appreciated that the invention is susceptible to modification, variation, and change without departing from the proper scope or fair meaning of the subjoined claims.
