Compound multi-function gym benches

#Machines or instruments for body or muscle building are generally divided into two kinds, one for a training center and the other for homes. The former are rather complicated and are equipped with various functions in one machine for many persons to use; the latter are mostly constructed for only one function in one machine or instrument to fit in the home environment.

#A person has to get various kinds of machines or instruments in order to obtain balanced training for every part of his body. Then these machines or instruments may occupy not a little room or space in the house, and cost a great deal as well. Hence, it is desirable if personal gym machines or instruments would have multi-functions, a compact construction, and occupy little space if they could be broadly used by private persons at home.

#Therefore, the inventor, having engaged in manufacturing gym machines for many years, has worked out this compound multi-function gym bench, which is usable not only at home but at a training center, too. This compact machine can replace common large or single-function ones. By changing the various parts of this bench, a person can use it for bike pedaling exercise, weight lifting or rope pulling either by hand or foot whether in a sitting, lying or standing position.

#FIG. 3 is a cross-sectional view taken on line 3--3 of FIG. 2.

#This compound multi-function gym bench comprises seat frame 1, hollow post 2, revolving discs 3, frame for pulling rope 4, weight post 5, weight blocks 6, pulling rope 7, pushing handle 54, and T-shaped handle 56 as its main parts.

#As FIGS. 1, 2, 3, 4 show, seat frame 1 includes a bent plate through an upper side of which is bored a square hole. A hollow square rod 11 is welded at the hole and extends slantingly down to a base. A supporting rod 111 is welded at the middle of rod 11 and extends slantingly upward. The lower end of square rod 11 is welded at the base of seat frame 1 so that rod 11 is steady and immovable. Then elevating rod 121 under seat 12 can be inserted and moved up and down in square rod 11. Axle tube 13 is welded on the cross point where square rod 11 crosses with supporting rod 111, and axle 131 is set with bearings 133 for combining with the pedaling parts. Besides, cushion 14 is set at the front of seat frame 1 and at both its sides are welded inserting bars 151 for one end of movable feet 15 to be inserted. Hollow post 2 is vertically combined with the rear of seat frame 1 with screws screwing together the front middle part of post 2 and one end of the plate of seat frame 1. The lower part of post 2 is welded to backward supporting case 21 and then screwed to the other end of the plate of seat frame 1. The lower end of post 2 is screwed to combining plate 16 of the base of seat frame 1. The hollow post 2 is combined together with seat frame 1 at three spots to solidify their structure. Wings 22 are set at both bottom sides of post 2 to strengthen the steadiness of this gym bench. Hanging hook 23 set at the upper part of post 2 is used to hook leaning cushion 231. Inserting bars 24 welded at both sides of the top part of post 2 is for the frame 4 for pulling rope to be inserted to stand upright. Wheels set at both rear bottom sides of seat frame 1 are used for moving this gym bench by tilting and pushing it. Side plates 18 are attached at both sides of seat frame 1 to impart neatness to its outward appearance. Lateral bars 101,102 set at the rear bent end of the plate of seat frame 1 are exposed to be hooked by T-shaped rod 103.

#As FIG. 5 shows, control pin 19 is used to arrest the position of the elevating rod 121 inside hollow square rod 11. The pin 19 is insertable through a cylinder 113 and a hollow threaded member 112. The cylinder 113 is threaded on the hollow member 112. Stop rings 191 on the control pin 19 engage opposite ends of a spring 192 for pressing the control pin 19 into a hole 122 of elevating rod 121 in stopping and keeping elevating rod 121 at its place. Spring 192 enables control pin 19 to be pulled out of hole 122 for changing the height of seat 12 and adjusting elevating rod 121 up or down along hollow square rod 11.
