Description: The present invention relates to 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 equipped with various functions in one machine for many people to use; the latter are mostly constructed for only one function in one machine or instrument to cope with the living environment. A person has to get various kinds of machine or instrument in order to conduct a 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 require quite a large amount of expenditure as well. So it may be a good idea that personal gym machines or instruments could have multi-functions, compact construction, and little space if they could be broadly used by private persons at home. A gym Set is known from the US-Patent 4 606 540 of the present applicant. This gym set combines the functions of weight lifting, foot pushing and rope pulling-weight exercises by the combination of various removable parts of the gym bench. In particular, this reference discloses a removable weight post and a removable frame for the pulling rope as disclosed in the present invention. However, the known apparatus does not provide for the additional function of bike pedalling so that the functions which may be exercised on this known gym set is somewhat limited. Furthermore, the addition of more exercise functions to the known gym set would result in a very bulky apparatus. From FR-A-2 135 822 a multi-function physical exercise apparatus is known which in addition to weight lifting, foot pushing and rope pulling-height exercises also provides for the function of simulating bike pedaling. However, this additional function results in the exercise apparatus being very bulky so that it is particularly unsuited for use in private dwellings, in which the space available for exercising is limited. In accordance with the present invention, a compound multi-function gym bench is provided having the functions of bike-pedaling, weight lifting, foot pushing and rope pulling-weight exercises by the various combinations of the various parts of the gym bench, comprising, a seat frame provided with an elevatable seat rotatable about 360°, pedaling parts, behind which a vertical hollow post standing on the ground is fixed to the frame, and two movable feet upon which a leaning cushion may be placed, a removable weight post that can be moved up and down inside the hollow post, said weight post being partly exposed at a rear opening of the hollow post and having removably attached thereto in the region of the exposed part a hooking hole for hooking a pulling rope, a pushing handle adjustable in its using angle, and a lateral rod provided at both ends with a soft cushion, wherein a T-shaped handle can be connected to or taken off the lateral rod, a frame for the pulling rope having at its top end a pivotable hanging wheel for slidably supporting the pulling rope, the frame being removably mounted on inserting bars provided at both sides of the hollow post, a T-shaped rod which may be hooked onto a lateral bar set provided at a bending part of the rear of the seat frame, the T-shaped rod having a wheel for the pulling rope to hook around, the leaning cushion being mountable in front of the hollow post for leaning thereagainst or being mountable on the movable feet to provide for an extended seat, and wherein said seat frame is made up of a long bent plate provided at both sides with removable side plates and includes, a square hole at the top thereof, through which a hollow square rod extending down to the bottom thereof is welded together with the seat frame and in which a movable control pin is set in its upper part, an elevating rod placed inside the hollow square rod with its upper end fixed beneath the revolving seat, the elevating rod having at least one hole through which the control pin may be inserted for stabilizing its position and adjusting its height, a supporting rod which crosses the hollow square rod, and an axial tube provided at the crossing point of the supporting rod and the hollow square rod and having a turning axle provided therein, wherein a revolving disc is removably provided on both ends of the turning axle and a friction wheel is provided inside one of the revolving discs on the turning axle. Therefore, the inventor, having been engaged in manufacturing gym machines 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 in 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.

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 figures 1,2,3,4 show, seat frame 1 is made up of a plate bended, and on its upper side is bored a square hole, and hollow Square rod 11 is welded there going slantingly down. Moreover, supporting rod 111 is welded at the middle of elevating rod 121, extending slantingly upward. The lower end of square rod 11 is welded at the plate of seat frame 1 so that rod 11 can be steady and immovalbe. 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 132 is set with bearing 131 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; with the lower part of post 2 is welded backward supporting case 21 and then screwed with the other end of the plate of seat frame 1; the lower end of post 2 is screwed with combining plate 16 of the plate of seat frame 1; then hollow post 2 is combined together with seat frame 1 at three spots to solidify their structure, and besides, wing 22 is set at both bottom sides of post 2 to strenghthen the steadiness of this gym bench. Hanging hook 23 set at the upper part of post 2 is to hook leaning cushion 231. Inserting bars 24 welded at both sides of the top part of post 2 is for frame 4 for pulling rope 7 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 tiliting and pushing it. Side plate 18 are attached at both sides of seat frame 1 to give neatness of its outward appearance. Lateral bars 101,102 set at the rear bending part of the plate of seat frame 1 are exposed to be hooked by T-shaped rod 103. As Figure 5 shows, control pin 19 is used to stop elevating rod 121 inside hollow square rod 11 by inserting through cylinder 113, hollow screw 112 set on elevating rod 121; cylinder 113 is screwed together with hollow screw 112. Besides, there is stop ring 191 on control pin 19 and spring 192 for pressing control pin 19 into hole 122 of elevating rod 121 in stopping and keeping elevating rod 121 at its place; spring 192 can also make 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. Revolving discs 3 are set at both ends of axle 132 extending out of axle tube 13 by means of square pin 133 and a screw 134. Friction wheel 31 set between one of revolving discs 3 and axle tube 13 turns around with axle 132 and friction band 311 put around friction wheel 31 functions to adjust mutual frictional force, and also to adjust the revolving force of both revolving discs 3 that revoloves together with axle 132. One end of friction band 311 is attached on supporting rod 111 and the other is connected with control button 314 by means of spring 312 and rope 313; turning control button 314 can change the tighness of friction band 311 against friction wheel 31. But this art is well known, so its detailed description is omitted, The revolution of revolving discs 3 is effected by pedals 30 shown in figure 6. Pedals 30 can be pushed up and stored in concave hollow 32 in revolving discs 3, in which a couple of combining ears 321 are set to connect pedals 30 by means of square holes 322 which coincide with square holes 302 of combining ears 303 of axle 301; then square control rod 33 laterally inserts through those holes 322,302. Said control rod 33 shown in figures 6,7 is a square rod cut with two ring grooves 331, whose distance between is just the same as that of two combining ears 303 of axle 301. Besides, spring 332 is put at one end of control rod 33 and screw 334 with washer 333 is set at the other end to combine control rod 33 with pedal 30 so that pedal 30 can be pulled down or pushed up in concave hollow 32. As figure 8 shows, hollow post 2 cut with lenghwise opening 20 stands vertically on the ground, and weight post 5 combines with post 2, able to slide up and down inside post 2 by means of wheels 251 attached with wheel seat 25. Two inserting bars 24 are set at both upper sides of post 2 for frame 4 for pulling rope 7 to insert in. Frame 4 for pulling rope 7, as figure 18 shows, has hanging wheel 41 at the top which can change to face forward or backward for pulling rope 7 to be hung on. Figure 8 also shows how weight post 5 is combined with hollow post 2. Weight post 5 has lengthwise opening 50 and is to be inserted from the top into the inside of post 2 with its rear exposed out of opening 20. The position of weight post 5 is to be changed and stabilized inside post 2 by sliding wheels 251 and three pairs of sliding wheels 51 set on both sides of weight post 5. Sliding wheels 251,51 are shaped , as figure 9 shows, conical at its outside to reduce lateral friction gaining the least resistance during their gliding movement up and down. Weight post 5 has at the top hanging hole 52 to be hooked by one end of pulling rope 7, and a pair of semi-circle combining plates 53 set at both sides below hanging hole 52 for combining pushing handle 54 so that handle 54 can be adjusted and used in different angles. Moreover, a couple of triangular plates 55 are set on both the under side of weight post 5 for fixing two guiding plates 551, which are fixed with lateral rod 552 with soft cushions at both its ends and have a combining hole 554 for connecting T-shaped handle 56 for leg exercise shown in figures 8,10. T-shaped handle 56 has axle tube 561 for an axle to insert through in combining with guiding plate 551 inserting through combining holes 554 at the same time. Weight block arm 562 can be put on or taken down at the middle of T-shaped handle 56 for loading weight blocks 6. Soft cushions 563 are attached at both ends of the lateral bar of T-shaped handle 56 for feet to step on. In order to combine pushing handle 54 with two combining plates 53 of weight post 5, a plurality of matching holes are connected by guiding slot 531; axle 553 inserts through axle hole 53 of combining plate 53 and axle holes 542 of parallel arms 541 set on pushing handle 54; control rod 57 inserts through one of matching holes of combining plates 53 and holes 543 of parallel arms 541; and as figures 8, 11 show, the one end of control rod 57 becomes rod head 571 and the other end is bored with inside screw hole 572, and ring grooves 573 are cut at the same distance between as two combining plates 53; spring 574 is put around control rod 57 near rod head 571 to stabilize parallel arms 57 against combining plates 53 by not coinciding ring grooves with guiding slot 531 of combining plates 53. but coinciding ring grooves 573 with guiding slot 531 can make control arm 57 move along guiding slot 531 and consequently the angle of pushing handle 54 can be selected as needed. Weight block arm 540 is set extending out of the U-shaped part of pushing handle 54 for hanging weight blocks 6, as shown in figure 8. Pulling rope 7 is made of common wire rope with one end hooked at hooking hole 52 of weight post 5 and the other end with grip 72 through connecting piece 71. If pulling rope 7 is needed to be prolonged, it can be done using two connecting pieces. As figure 12 shows,connecting piece 71 has slot 711 for slot 711 of another piece 71 to couple with each other. As figure 13 shows, T-shaped rod 103 combined at the rear of seat frame 1 has hook 104 at the top, a lateral rod at the bottom, and wheel 105 set near the middle of the vertical part for pulling rope 7 to be guided. So in combining T-shaped rod 103, hook 104 should be hooked with lateral bar 101 and rested on lateral bar 102. Seat 12 shown in figure 14 has revolving base 120 which is able to turn around to any degree (0-360) and is quite commonly seen. Under revolving base 120 is slantingly fixed elevating rod 121 bored with several holes 122 for adjusting the height of seat 12. Figure 15 shows leaning cushion 231, which is to be hooked on hanging hook 23 of hollow post 2 by means of plate 232 set at the rear lower part of cushion 231. But leaning cushion can also be taken off hollow post 2 and placed on movable feet 15 with screws fixed through holes 234 of combining plate 233 set at one end of cushion 231. Then leaning cushion 231 becomes a long seat connected to seat 12 as figure 18 shows. Movable feet 15 are made up of pipes bended, one end standing on the ground and the other inserted in inserting bars 151 set at both front sides of seat frame 1. Figure 16 shows moving feet 15. Now how to combine this gym bench for various uses will be described. Figure 17 shows the fundamental form of this gym bench, wherein weight blocks can be hung on both sides of weight block arm 540 of pushing handle 54, and pushing handle 54 can be adjusted for its using angle by moving control rod 57. Then this bench can be used for weight lifting in a sedantary or lying postion. Next, if weight blocks are hung on weight block arm 562 of T-shaped handle 56, this bench can be used for foot pushing by stepping and pushing handle 56, but pushing handle 54 should be changed in its position so as not to disturb the foot exercise. Figure 18 shows that this gym bench shown in figure 17 is added with frame for pulling rope 4 and the seat is prolonged as well. Figure 19 shows this gym bench can then be used for training in pulling down rope 7 at the front. At this situation T-shaped handle 56 can be taken off. Figure 20 shows this bench is used for training in pulling down rope 7 at the rear. Figure 21 shows T-shaped rod 103 is added to this bench for pulling up rope 7 with feet stepping on it. Figure 22 shows the height of seat 12 can be adjusted according to the user's need, and pedals 30 can be pulled down from both sides of revolving discs 3 and the angle of pushing handle 54 can be adjusted for bike pedaling exercise. In general, this gym bench has characteristics of compact size, multi-function in a single unit, easy manipulation in changing its parts, and versatile adaptability in homes or offices or training centers. And actually produced sample has shown that this gym bench possesses higher practical value than other gym machines on the market do.
