Detailed description of the invention:

Explanation for example to the design below in conjunction with the accompanying drawings.

As shown in Figure 1 and Figure 2, the design comprises a circle and closes several supporting legs 2 equally distributed under conglobate guide rail 1 and guide rail, and supporting leg is fixed on the ground being embedded in spacious smooth public body-building place, and the cross section of guide rail 1 is that arcuation is girdled the waist shape；One inverted tool resilient U-shaped wheel carrier 3 is left by its end opening, right dual-side is fixedly connected with three onesize and horizontal guide wheels 4 being installed on sustained height position, the distributing position of three guide wheels be under left side under a right edge placed in the middle before and after each one, in isosceles triangle shape, wheel carrier 3 rides over the arcuation of guide rail 1 by guide wheel 4 folder and girdles the waist position, narrower guide wheel wheel face be trapped in the triangular layout of outer two in guide rail both sides with a tight waist and guide wheel all can ensure to take turns rack device stable on guide rail before and after run without derailing easily, preferably bear operating outside torsion and there is the directivity of good laminating guiderail track, U-shaped wheel carrier 3 preferably uses the processing of elastic preferably steel material, should have certain opening elastic, as shown in Figure 3；The right and left of wheel carrier 3 is all drilled with circular hole at the position being in the guide rail heart centered above, wherein slightly smaller the fixing of the circular hole on left side wears a clamping screw 10 of ining succession, the slightly larger activity of circular hole in right edge has the sleeve pipe 9 of the female thread threadeded with clamping screw in wearing a tyre boss of ining succession, sleeve pipe 9 is threadeded closely by the screw thread on its inwall with clamping screw 10, the boss position of sleeve pipe by the circular hole side bumper in right edge on the right side of wheel carrier, the combination length of clamping screw 10 and sleeve pipe 9 can be regulated by revoling tube 9, that is the openings of sizes of U-shaped wheel carrier 3 can be regulated, combination tightness between regulation guide wheel 4 and guide rail；The left end of one round bar shape handrail 5 diametrically has the thickness notch 6 slightly larger than sleeve pipe 9 right-hand member diameter, the two activity is worn even by the circular hole near sleeve pipe right-hand member and on notch 6 by a pin rod 7 in inserting notch the most between two parties and rivets, as shown in Figure 3, Figure 4 in termination by the right-hand member of sleeve pipe again；nullThe thickness circular cushion block 8 slightly larger than guide wheel radius of ining succession is worn on sleeve pipe between the right edge of the left side of handrail 5 and wheel carrier 3，So，The just citing of the basic structure of the grab rail device that falls back away of the design is described，It is illustrated in figure 4 a kind of location status of the design: use state，The most whole device is tap-like，Handrail level is overhanging to facilitate the double-grip of people to exert a force，Device can give both arms powerful support in vertical direction and horizontal direction，Person taking exercise can gently lean on the outer edge surface of guide rail 1 and pull handrail easily and fall back away and carry out exercise，If now wishing to increase some reversal interlocking relay，He can drive sleeve pipe 9 to rotate to tighten the opening of wheel carrier 3 by suitable rotating handrail 5，Promote guide wheel 4 clamping guide-rail 1 of both sides，Resistance when tractive handrail is advanced will suitably increase naturally，Otherwise，Inverse rotation operation handrail can promote wheel carrier to magnify opening because of natural resiliency，The grip force of guide wheel clamping guide-rail reduces，Resistance when tractive handrail is advanced then can reduce；nullWith finishing，Then handrail 5 half-twist angle (can be had following change: be transformed into anterior-posterior horizontal shape by upper and lower vertical configuration by as Fig. 4 shape is transformed into Fig. 2 shape such as a example by the location status of pin rod 7，Now provide condition for handrail 5 around the backspin of pin rod 7，Otherwise，The action that backspin reclaims cannot operate)，Press bar down，The notch 6 of handrail left end and pin rod 7 can coordinate handrail backspin to become recovery shape vertically downward to take to reduce peripheral space，The left side of handrail 5 can be supported slightly larger than the thickness of guide wheel 4 radius size by the cushion block 8 outside wheel carrier 3 right edge because of it，Sagging condition of providing convenience is reclaimed for it，If being not provided with the sagging of this cushion block bar may be in the skewed of non-perpendicular downward shape by the outer support of guide wheel，This cushion block is set simultaneously and it also avoid directly contacting frictionally damage and being conducive to protecting critical piece of handrail left side and wheel carrier，Handrail has been recovered to downwards the elastic external support force of pendant position rear wheel frame can also increase the stability of its pendant position，Will not arbitrarily rock and wave，And when re-using，Handrail can be lifted above and return to former horizontal，Even if the most rotating handrail does not becomes to use shape handrail can be in horizontal horizontal yet，Because the outer support elastic force that wheel carrier has can give this support，Can 90 ° of angles of rotating handrail or 45 ° of isogonisms foregoing when tractive uses，Handrail all can give both hands both arms with vertical direction and the support force of direct of travel，Meet effective performance of the design device all uses function，In fact，Above-mentioned so-called use state or other states are all a kind of citing references，User can have the practical situation of apparatus takes the circumstances into consideration to select，It is not required to stick to very much describe introduce.The a set of wheel carrier handrail that has been a device represented as shown in Figure 1, in fact can set up to close together by such many set wheel carrier armrest systems has many people to temper use to facilitate on conglobate guide rail simultaneously, when only a few peoples use the handrail having to leave unused, the wheel carrier handrail advanced can naturally promote the idle wheel carrier handrail run into advance along guide rail simultaneously, do not interfere with use of turn-taking, also can hand steered handrail make before push dynamic, such as shape of turning a millstone, also it is a kind of body-building, simply needs with the direct of travel coordinating and unifying of the people of this device；The closing circle of aforementioned guide rail can be circular can also be oval or other circular arcs, the active force to handrail that the most only circular is provided be only uniform and stable reliably.The design can fall back away the support handrail that the people one of body building prevent for safety falling, a reverse traction force can also be increased as required to increase train on simultaneously, being a new product in body-building apparatus field, the sport and body-building activity for people adds the newly selected.
