Exercise apparatus

[0002] 1. Field of the Invention

[0003] This invention relates to an exercise apparatus and more particularly the present invention which is directed to an exercise apparatus for the conditioning of the three groups of muscles, the hamstring muscle, the quadriceps muscle and the maximus gluteus muscle.

[0004] 2. Description of the Prior Art

[0005] Many devices exist for exercising various parts of the body for commercial and home use. Some of these devices are:

[0006] U.S. Pat. No. 5,575,741 to Robert Fan.

[0007] This exercise apparatus simulates horse riding type and rowing type exercise.

[0008] U.S. Pat. No. 4,526,013 to W. R. Dofel.

[0009] This exercise device provides a mechanical resistance assembly which employs a resistant strap which is stretched by use of a pulley system pulled by the user.

[0010] U.S. Pat. No. 5,094,450 to Steams.

[0011] This exercise machine provides for abdominal exercising. This machine also allows a chest pod to rotate, which is resisted by either a viscous fluid resistance or stacked weights.

[0012] U.S. Pat. No. 5,112,287 to Brewer.

[0013] This exercise apparatus employs a resistance that is experienced by a person exerting a force to pull or push the body engaging members. The resistance can be varied.

[0014] It is the object of the present invention to provide an exercise apparatus useful in connection with the performance of exercising at least three groups of muscles.

[0015] It is another object of the present invention to exercise the maximus gluteus muscle in addition to two leg muscles.

[0016] It is yet another object of the present invention to provide an exercise apparatus that can be efficient and economically manufactured.

[0017] Briefly, in accordance with the present invention, there is provided an exercise apparatus that sits on a floor surface and has an rectangular backrest. Two semi-circular members attached to the backrest also sit on a floor surface. Pivotally attached to the backrest is a brace that has a roller resting on the floor surface on the other end. The brace has a sliding member that is fit over the brace and the sliding member is adjusted by push pins. The sliding member adjusts the tension in the tensioning members. Two handlebars are attached to the lower end of the backrest of the exercise equipment When a person exercising pushes back on the backrest, the backrest rotates and lifts the person exercising off the floor surface. The person exercising pushes back as far as desired and then relaxes and the person exercising will return to sit on the floor surface. This movement is repeated until a complete workout is obtained in the three previously mentioned muscle groups. It is noted that a person exercising must hold their feet flat on the floor. A person exercising must also have non-slip shoes such as gym shoes to provide the ability to push back on the backrest of the exercise equipment.

[0018] These and other objects, features and advantages of the present invention will become more readily apparent upon detail consideration of the following Description of the Preferred Embodiment with reference to the accompanying drawings.

[0019] In the drawings that illustrate the best mode presently contemplated for carrying out the present invention are:

[0020] FIG. 1 is an isometric view showing the back of the present invention.

[0021] FIG. 2 is a left side view of the present invention.

[0022] FIG. 3 is a rear view of the present invention.

[0023] FIG. 4 is a front view of the present invention.

[0024] The novel features which are believed to be characteristic of the invention, both as its organization and its method of operation, together with further objects and advantages thereof, will be better understood from the following description in connection with the accompanying drawings in which a presently preferred embodiment of the invention is illustrated by way of example. It is expressly understood, however, that the drawings are purposes of illustration and description only, and are not intended as a definition of the limits of the invention.

[0025] Turning now to FIG. 1 there is seen a perspective view of the present invention generally shown as 10. The backrest 12 made of a solid material has cushioning material on the front side which is also covered with a waterproof material 14. The headrest 16, also made of solid material, is covered with a cushioning material and also covered with a waterproof material 18. The headrest 16 has a structural member 20 attached to the back of the headrest 16. The structural member 20 has attached thereto a structural member 22 that is further attached at 90 degrees to another structural member 24. The backrest 14 has attached a horizontal structural member 26 which has a vertical structural member 28 attached only to the horizontal structural member 26. Vertical structural member 28 is not attached to the backrest 14. A bracket 30 is fitted around both structural member 24 and structural member 28 whereby structural member 24 may slide up or down to adjust to the requirement of the person exercising. Once the adjustment is made, thumb screw 32 can be tightened to hold the headrest in place.

[0026] Also attached to the backrest 12 is rod 36 which has attached thereto hand holds 38 and 40. (Seen in FIGS. 3 and 4). The backrest 12 has attached a vertical structural member 42 which has a horizontal structural member 44 attached 90 degrees to vertical structural member 42. Attached to horizontal structural member 44 is a rod 48 that holds one end of elastomer members 50 and 52. Bar 48 has push pins 54 and 56 (not shown) to prevent the elastomer members 50 and 52 from coming off rod 48. Vertical structural member 42 has affixed thereto a bracket 58 that pivotally holds a brace 60. Brace 60 has a sleeve 62 that slides along brace 60. Sleeve 62 has affixed thereto rod 64 that holds one end of elastomer members 50 and 52. Sleeve 62, when slid along brace 60, provides tensioning of elastomer members 50 and 52. The adjustment is held in place by push pins protruding through a hole in sleeve 62.

[0027] On the bottom end of brace 60 there is a roller 68 that rolls on the same floor surface that backrest 12 sits. FIG. 1 also shows semi-circular members 70 and 72 that are covered with a non-slip material. Semi-circular member 70 and 72 also sit on the same floor surface that the backrest 12 sits.

[0028] FIG. 2 shows a left side view of the present invention. The right side is a mirror image.

[0029] FIG. 3 shows a back side of the present invention.

[0030] FIG. 4 shows the front side of the present invention.

[0031] The operation of the exercise apparatus is very easy. When the person exercising sits on the floor surface where the backrest sits and puts their hands on the hand holds 38 and 40, the person exercising then places their back on the backrest and their head on the headrest. The person exercising then pushes back with their back and the exercise apparatus rotates on the semi-circular members 70 and 72. Simultaneously roller 68 rolls on the floor surface and this motion provides a tension in elastomer members 50 and 52. The motion of pushing back by the person exercising lifts the person exercising off the floor surface and the rotation of the exercise apparatus on the floor surface increases the tension in the elastomer members 50 and 52. This movement of the person exercising exercises the three groups of muscles previous indicated. When the person relaxes the exercise apparatus returns to the initial position. This movement is repeated until a complete workout is obtained.

[0032] The present disclosure includes that contained in the appended claims as well as that of the aforegoing description. Although this invention has been described in this preferred form, with a certain degree of particularity, it is understood that the present disclosure of the preferred form has been made by way of example and that numerous changes in the details of construction and the combination and arrangement of parts maybe resorted to without departing from the spirit and scope of the invention.
