Medicine Ball Torso Rack

This invention relates to an exercise machine and, more particularly, to a machine which is designed to be best used with a medicine ball.

Heretofore, one effective exercise for use with a medicine ball was for two users to stand or sit back-to-back. Upon a first user grasping the medicine ball the first user would rotate the torso in a clockwise or counterclockwise direction and hand it to the second user. Once received the second user would then rotate the torso so as to return the medicine ball to the opposite side of the first user. This exchange of the medicine ball would continue between the users in either clockwise or counterclockwise direction so as to exercise the muscles of the users' torsos. Although this exercise is effective in operation, the absence of a workout partner precludes one from effectively performing this exercise.

In response thereto I have designed a device which enables one to perform a similar exercise with a medicine ball but without a workout partner. Generally my now preferred device comprises a frame with a ball track attached thereto, the track presenting a course for rolling movement of a medicine ball between opposed ends of the track. The track is pivotally mounted to the frame so that the opposed ends of the track can be pivoted to various relative positions at which one end of the track is elevated relative to the lower opposed end of the track. A seat on the frame allows the user to sit with the user's back to the track. Upon rotation of the torso the medicine ball is initially positioned by the user at the elevated end of the track. The medicine ball then rolls to the opposite lower end of the inclined track. The user rotates the torso in an opposed direction toward the lower end of the track to recover the medicine ball. This torso motion between the initial ball placement and ball recovery positions exercises the torso muscles of the user. After a desired number of repetitions the track can then be pivoted so that the lower end becomes the elevated end. The user then performs the initial positioning and ball recovery movements in opposed directions thus exercising the opposed muscles of the torso. The elevation of one end of the track above the horizontal can be adjusted so as to vary the ball's rolling speed and thus the degree of exertion needed by the user to move between the ball placement and recovery positions. Foot holds on the frame allow the user upon facing the track to do sit ups. Various types of exercises can be utilized in connection with my device.

Accordingly, it is a general object of this invention to provide an exercise device for exercising the torso muscles.

Another object of this invention is to provide a device, as aforesaid, which enables one person to perform torso exercises with a medicine ball.

A further object of this invention is to provide a device, as aforesaid, which eliminates the need to have a workout partner when performing exercises with a medicine ball.

Still a further object of this invention is to provide a device, as aforesaid, which adjusts the degree of exertion needed to be utilized by the user.

A further object of this invention is to provide a device, as aforesaid, having a track for the medicine ball, the track being adjustable in slope to vary the speed and direction of the medicine ball along the track.

Another object of this invention is to provide a device, as aforesaid, which enables one to perform various medicine ball exercises with ease, effective and convenience.

Another particular object of this invention is to provide a device, as aforesaid, which assists the user in the development of speed, flexibility and coordination.

Other objects and advantages of this invention will become apparent from the following description taken in connection with the accompanying drawings, wherein is set forth by way of illustration and example, a now preferred embodiment of this invention.

Turning more particularly to the drawings, FIG. 1 shows the torso rack as comprising a support frame 100. The frame 100 includes a horizontal base frame 11 which comprises a first ground adjacent base strut 11a with normal ground-adjacent front 11b and rear 11c struts at opposed ends of strut 11a. A vertical frame extends from the strut 11a and comprises a front post/column 10 having a seat 8 thereon. Seat 8 is attached to a depending post 8b which nests in the vertical column 10. Up and down movement of post 8b within column 10 adjusts the seat 8 height. Seat 8 is held at a selected height by a pin 8a extending through an aperture in the column 10 and a selected aperture 8c of a plurality of apertures in the seat post 8b.

Vertically extending from the rear of the base frame strut 11a is a rear strut 14. A vertical strut 13 extends from a cross brace 20 extending between front post 10 and rear strut 14. Struts 13, 14 present upper ends 13a, 14a. A shaft 12 rotatably extends between the upper ends 13a, 14a of struts 13, 14. An inner solid shaft 15 extends through the free ends 13a, 14a of struts 13 and 14 and through shaft 12 and presents an end beyond strut 14. A rotation of inner shaft 15 will likewise rotate the surrounding cylindrical shaft 12.

Attached to this shaft 12 is a track 2 for the medicine ball 1. The track is presented by a frame presenting a rear rail 4 and front rail 4a having stop pads 5, 6 at the first and second opposed track ends. The rails 4, 4a are spaced apart to allow a medicine ball 1 to seat therebetween. The rear rail 4 is slightly higher than the front rail 4a to preclude the medicine ball 1 from unseating during medicine ball rolling movement.

Extending from the rear rail 4 at the midpoint is thereof is a depending flange member 40 which is connected to the outside shaft 12. The midpoint of front rail 4a itself is also connected to shaft 12. Thus, rotation of shaft 15 will rotate shaft 12 and pivot the track 2 connected to shaft 12.

Attached to the opposed extending end of shaft 15 is a triangular-shaped plate 3. The plate 3 has a plurality of apertures 3a-3g therein (FIGS. 4, 5). Further extending from the frame strut 14 is a bracket 14b presenting an arm with an aperture therein for extension of a pin 14c therethrough. Upon alignment of the aperture in bracket 14b with a selected plate 3 aperture of a plurality of apertures 3a-3g, the shaft 15 rotates which concurrently rotates outer shaft 12. Thus, track 2 will be concurrently inclined at a selected angle relative to the horizontal. An anchor screw 7 extends through the top of strut 13 and is user threadable to bear against an end of shaft 15 to preclude shaft 15 rotation. Thus, screw 7 further maintains the track 2 at a selected angle. The alignment of the left most aperture 3a, as viewed in FIG. 5, in plate 3 with the bracket 14b aperture provides the highest degree of elevation of the right track end (as viewed) as the counterclockwise movement of the slope selector 3 will likewise rotate the shaft 15 in a counterclockwise direction and thus elevate the right end of the track. Likewise, in rotating the plate 3 in a clockwise direction such that the opposed right most aperture 3g is in alignment with the bracket 14b aperture, the shaft 15 rotates in a clockwise direction and thus positions the opposed left end of the track at the highest elevated position. As above explained insertion of the pin 14c through the aligned plate aperture and bracket aperture maintains the slope of the track at the selected position. Accordingly, it can be seen that the slope selector plate 3 allows the opposed ends of the track to be positioned between their most elevated positions as well as positions therebetween as provided by the intermediate apertures found on the slope selector plate 3. As shown in the FIG. 5 the middle aperture of the plurality of apertures is in alignment with the bracket 14b apertures which places the track 2 at a relatively horizontal position.

Foot rests extend from the rear vertical strut 14. Upon the feet of the user being placed underneath these rests the user can do sit ups, if so desired.

A back pad 9 attached to post 9a is slidable within the upper cross brace 34 which joins struts 13, 14. A pin 9b extends through apertures in post 9a and strut 34 so as to maintain the desired displacement of back pad 9 from strut 13. Thus, as both the back pad 9 and seat 8 are adjustable, variously sized users can utilize the device in a seated position.

FIGS. 8 and 9 show the device in use. In FIG. 8 the seated user has his back to the track 2 and has first rotated his torso in a clockwise direction and placed the medicine ball at an initial position on the elevated end of the track 2. Upon release the medicine ball 1 will roll to the opposed lower track end. During this movement the user rotates his torso in an opposed counterclockwise direction so as to position the torso for recovering the medicine ball at the opposed end of the track. FIG. 9 shows a user at the recovery position for the medicine ball at the non-elevated end of the track. The back and forth movement of the user between the initial ball placement and ball recovery positions along with the weighted medicine ball exercises the muscles of the user. By use of the slope selector 3 as above described the angle of inclination the track 2 can be adjusted which will vary the speed of rolling movement of the medicine ball between the upper and lower ends of the track 2. Concurrently, the speed of user movement between the initial ball placement and recovery positions will also have to be adjusted according to the track 2 slope and the increase or decrease in ball speed. Also, the selector 3 can elevate either end of the track for initial ball placement. Thus the user's torso may rotate in an opposed direction between the initial and recovery positions so as to achieve an exercise balance.

Accordingly, it can be seen that the above combination of elements allows a user to perform various exercises in connection with the device 100, the type of exercises not being limited to that as above described. Moreover, the user need not be seated during performance of such exercises.

It is to be understood that while a certain form of this invention has been illustrated and described, it is not limited thereto except insofar as such limitations are included in the following claims and allowable functional equivalents thereof.
