The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As depicted in figs. 1 and 2, the handrail and the back cushion of the utility model design include:
One slide-able platform 10, main system is made of a holder 11 and a sliding seat 12, holder 11 is fixedly installed to the fixed position (as shown in Figure 4) of seat 20 both sides, and sliding seat 12 11 supports of seat that are fixed and can be done relative slip with holder 11;
One parallel linkage 30, include the swing arm connecting rod 32a that a master connecting-rod 31 and a pair of frame respectively are connected on the two ends of master connecting- rod 31,32b, this other end to the swing arm connecting rod then is articulated in sliding seat 12 again, therefore sliding seat 12 is except sliding on the surface of holder 11, it also is one of connecting rod of forming by parallel linkage 30, master connecting-rod 31 wherein is in order to carrying back cushion 40 (as shown in Figure 3 and Figure 4), support by this parallel linkage 30, the user just can move to back cushion 40 different positions or different angles (shown in Figure 10-12) arbitrarily, make user's both arms obtain than comfortable support with shelve.
In the preferred embodiment that the utility model disclosed, sliding seat 12 towards the place ahead of seat 20 or the rear slide, can allow the user according to the length of its arm and mobile sliding seat 12 and back cushion 40 like this, so that obtain than the comfortable support position.Holder 11 and sliding seat 12 in conjunction with and the means that can slide relatively many kinds are arranged, what disclosed as shown in Figure 2 is the design of adopting dovetail groove and dovetail block, at the both sides of the edge of holder 11 design dovetail block 110, then design the dovetail groove 120 that just can be coupled in dovetail block 110 in the both sides of the edge of sliding seat 12, sliding seat 12 just can be together coupled to each other with holder 11, and do relative slip.
In order to prevent that sliding seat 12 breaks away from holder 11 because of slip, in this slide-able platform 10, also design has a kind of spacing escapement, include: the limited post 121 that is fixedly installed on the stop part 111 of holder 11 and is arranged on sliding seat 12, by limited post 121 and stop part 111 stopping each other, just can prevent sliding seat 12 disengaging holders 11 (as shown in Figure 6 and Figure 7); Stop part 111 is positioned at the side of holder 11 towards sliding seat 12, it can be a kind of element or fuel plate of projection, and limited post 121 preferably adopts movable design, the nut that is arranged in sliding seat 12 as use is as limited post 121, so limited post can selectivity be moved to the position that can interfere with stop part 111, in order to stop sliding seat 12 to break away from holder 11, or be moved into not the unlocked position that can interfere with stop part 111, so that the user can take off sliding seat 12 where necessary on holder 11.
