Referring to the drawing in detail reference numeral 10 designates a vertical panel which is attached to a wall stud by the screw fastener 11 so that the panel is held fixedly against the'wall 12. The back side of the vertical panel 10 is provided with three cross members 13 attached thereto. A cross member 14 is attached to the bottom of the panel 10 and projects forwardly from the panel. A front panel 15 is attached to the top surface of the bottom member 14 by the hinges 16 so that the front panel 15 may be swung from its vertical position shown in FIG. 1 to its horizontal position shown in FIG. 2 in which the panel is lying flat on the floor. When foldable side braces 10a and 10b which are pivotally attached to the sides of

panels

10 and 15 are provided therebetween, the vertical panel 10 need not be attached to a stud by fastener 11.

When the panel 15 is in the vertical position shown in FIG. 1 it is embraced by the straps l7 and 18 which are secured together by the lock 19. For this purpose the strap 17 is attached to the side and back of the back panel 10 by a hinge l9 and the strap 18 is attached to the other side and back of the panel 10 by the hinge 20. One of the

straps

17 or 18 is provided with a lockreceiving loop which is adapted to be inserted through a slot in the other strap so that the lock 19 may be inserted through the loop to secure the straps together when the front panel 15 is in its vertical position.

A top member 21 is attached to the top of the panel 10 and overhangs the top of the panel 15 when this panel is in its vertical position. A short panel 22 is attached to the vertical panel 10 a short distance from the bottom by hinges such as the hinge 23 as shown in FIG. 6 so that this short panel may be swung into its horizontal position. The top of the panel 22 is provided with a member 24 which is attached to the top edge portion thereof by the hinges 25 as shown in FIG. 2.

Member 24 is provided with magnets 26 attached thereto to cooperate with and grip magnetic armatures attached to the back panel as shown in FIG. 6. Thus when the member 24 is folded against the panel 10 the magnets 26 grip the armatures 27 and hold the panel 22 and the member 24 in raised position. When the panel 22 is in its lower position shown in FIG. 6 member 24 is in its vertical position for use as a foot brace in exercises to be described hereinafter.

Panel 10 is provided with

eyebolts

28, 29, 30, 31 and 32 which are firmly attached to this panel and panel is provided with an eyebolt 33 which is likewise firmly attached thereto. The purpose of these eyebolts will be discussed hereinafter in the description of the exercises to be performed with this apparatus. Likewise, the purpose of the pad 34 and shoe straps 35 which are attached to the top or inner surface of the panel 15 will also be discussed in connection with the various exercises performed with this apparatus.

This apparatus is to be employed in conjunction with a friction device 36 shown in FIG. 3 which may be of the type disclosed in U. S. Pat. Nos. 3,197,204 and 3,411,776. The friction device 36 is provided with a loop or hook so that it may be attached to selected eyebolts 28-33 of this apparatus and it is also provided with a cord 38 that is wrapped around a friction member therein a predetermined number of turns. When this apparatus is to be used for exercising the panel 15 is lowered to the floor as shown in FIG. 2 and the friction device 36 is attached to one of the eyebolts, for example, eyebolt 29 as shown in FIG. 4. When the person 39 desires to perform certain arm exercises as shown in this figure, he grips the handle 40, which is attached to one end of the cord 38, with both hands and endeavors to pull the cord through the friction device 36. When the operator desires to perform certain back exercises he attaches the friction device 36 to the eyebolt 33 of panel 15 and stands with his feet positioned on opposite sides ofthis eyebolt as shown in FIG. 5. In this exercise handles such as the handle 40 are attached to opposite ends of the cord 38 and the operator grips these handles, one in each hand, and endeavors to pull the cord back and forth through the friction device, first with one hand and then with the other.

When the operator desires to perform rowing-type exercises he lowers the short panel 22 as shown in FIG. 6 and moves the member 24 into its vertical position to serve as a foot brace. Then by sitting on the pad 34 he braces his feet against the member 24 and grips the handle 40 which is attached to one end of the cord of the friction device 36. He attempts to pull the cord through the friction device, thus exercising his back muscles.

The back and arm muscles may also be exercised by attaching the friction device 36 to the eyebolt 32 as shown in FIG. 7. In this exercise the operator inserts his feet under the straps 35 and sits on the pad 34 while gripping the handle 40 with both hands he endeavors to pull the cord 38 through the friction device 36. Exercise such as is obtained by pedaling a bicycle may be obtained when this apparatus is arranged as shown in FIG. 8. In this case the ends of the cord 38 are looped around the feet as shown. Friction device 36 is attached to the eyebolt 32 and the operator lies on his back on the pad 34, and braces his hands against the panel 22. While in this position the operator endeavors to pedal his feet and draw the cord 38 back and forth through the friction device 36.

The exercise shown in FIG. 9 is performed by attaching the hook 37 of the friction device 36 to the eyebolt 33. In this exercise one end of the cord 38 is looped around the handle 40 and the operator endeavors to pull the cord through the friction device 36 while applying additional friction to the cord entering the friction device 36. This exercise strengthens the operator's leg muscles and also at the same time exercises his arms and back to a certain extent. In the arrangement shown in FIG. 10 the friction device 36 is attached to the top eyebolt 28. The operator stands facing the panel 10 and his arms are extended horizontally forward. In this position the operator grips the handle 40 with both hands and pulls downward on the cord 38 against the friction in the device 36 while at the same time he applies additional friction on the part of the cord entering the device 36.

While we have shown and described certain preferred embodiments of the invention, it is apparent that the invention is capable of variation and modification from the forms shown so that the scope thereof should be limited only by the proper scope of the claims appended hereto.
