The specific embodiment

For fully understanding the purpose of this utility model, feature and effect, now by following specific embodiment, and conjunction with figs., this utility model is described in further details, be described as follows:

See also Fig. 1 to Fig. 3, it is respectively the exploded view of this utility model specific embodiment, the local enlarged diagram of this utility model the 1st figure A part and the outside drawing of this utility model specific embodiment.As shown in the figure: the adjustment structure of this utility model wheelchair armrest comprises a support unit 1, a back cushion 2 and a pushing tow unit 3 at least.

Above-mentioned support unit 1 comprises that at least a straight-bar 11, one be located at the cross bar 12 of straight-bar 11 1 ends, and a plurality of blocking parts 13 that are movably arranged on cross bar 12 at least one sides, wherein this straight-bar 11 is provided with a plurality of joining holes 111, these cross bar 12 at least one sides are provided with a plurality of storage tanks 121 that can ccontaining blocking part 13, and each blocking part 13 have at least one be arranged on elastic parts 131 in the storage tank 121, and an end is resisted against on the elastic parts 131 and the other end extends the spacing tip 132 of storage tank 121.

This back cushion 2 and support unit 1 movable the combination, it simultaneously is provided with activity and is crossed on chute 21 on the cross bar 12, and a side of this back cushion 2 has the locating hole 22 that is communicated with chute 21, and this locating hole 22 is corresponding with the blocking part 13 of appropriate location by moving of back cushion 2.

This pushing tow unit 3 is movably arranged in the locating hole 22 of back cushion 2, and can be corresponding with the blocking part 13 of appropriate location against, wherein this pushing tow unit 3 comprises a press section 32 that is arranged in the locating hole 22 and can extends back cushion 2 one examples against push rod 31, an end and push rod 31 butts and the other end of the spacing tip 132 at least, reaches one and be set on the push rod 31 and two ends are resisted against the elastic parts 33 of locating hole 22 bottoms and 32 bottom surfaces, press section respectively.

See also Fig. 4 to Fig. 6, it is respectively the back cushion clip state diagram of this utility model specific embodiment, the back cushion of this utility model specific embodiment is removed the back cushion mobile status figure of clip view and this utility model specific embodiment.As shown in the figure: when using (please cooperate simultaneously and consult Fig. 1), two support units 1 can be utilized the joining hole 111 on its straight-bar 11 to cooperate fixation kit to be separately positioned on the both sides (scheming not shown) of wheelchair at least, use as handrail; And under unadjusted state, the spacing tip 132 front ends of this blocking part 13 utilize the elastic force clip of elastic parts 131 in the locating hole 22 of back cushion 2, its rear end then is arranged in the storage tank 121 of cross bar 12, make back cushion 2 spacing on the appropriate location of cross bar 12, when user because of standing up or when carrying out other action and needing to adjust the position of this back cushion 2, can directly push the press section 32 of this pushing tow unit 3, make this press section 32 promote push rod 31 and elasticity of compression assembly 33, with the front end of these push rod 31 pushing tows at this spacing tip 132, make in these push rod 31 retraction storage tanks 121 and elasticity of compression assembly 131, make this spacing tip 132 leave the locating hole 22 of back cushion 2, at this moment, user can be with before this back cushion 2, press section 32 is moved and decontroled in the back, the spacing tip 132 is resisted against on the side wall surface of chute 21, before allowing back cushion 2 on cross bar 12, carry out with its chute 21, back telescopic slide, when treating that back cushion 2 moves to the pre-position, can make the spacing tip 132 front ends of set another blocking part 13 on this cross bar 12 utilize the elastic force clip of elastic parts 131 in locating hole 22, the rear end of the spacing tip 132 then is arranged in the storage tank 121 of cross bar 12, can be spacing once more on cross bar 12 after back cushion 2 is adjusted to appropriate location, finish the adjustment of back cushion 2 and spacing moving thus, when this utility model being combined on the wheelchair use, has preferable convenience as handrail.
