Detailed description of the invention
As shown in Figures 1 to 6, the wheelchair that the present invention has sideward sliding function has body frame structure for automotive, backrest and front and rear wheel structure, and vehicle frame is used for supporting wheelchair entirety and seat part, and vehicle frame rear is provided with two backing tubes, is used for supporting occupant's backrest and promotes wheelchair.Above-mentioned front and back wheel is used for supporting wheelchair and movement thereof.
Above-mentioned wheelchair trailing wheel place is respectively equipped with two lateral movement mechanisms, is used for realizing the lateral sliding function of wheelchair.This lateral movement mechanism comprises underframe pipe 1, sidesway wheel bar 2, connecting rod 3, connection sliding block 4, foot control part 5, hand lever 6 and extension spring 7; Above-mentioned underframe pipe is the connection tube between wheelchair front and rear wheel, for a part for wheelchair frame, using the installation basic part as lateral movement mechanism, above-mentioned sidesway wheel bar 2 is rotatably connected on underframe pipe front end, sidesway wheel bar tilts to stretch to wheelchair rear side, and its end is provided with sidesway wheel 21, this sidesway wheel replaces wheelchair trailing wheel and lands in the time of wheelchair sidesway, realizes the sideward sliding function of wheelchair together with wheelchair front wheel; Above-mentioned connection sliding block 4 is slidably connected with underframe pipe, and is rotationally connected by connecting rod 3 and sidesway wheel bar 2, and underframe pipe, sidesway wheel bar, connecting rod form bar linkage structure like this.
Above-mentioned connection sliding block 4 is double-decker, connected to merge by connecting pin and form first, second, third and fourth node 81,82,83,84, wherein the 3rd node 83 is and the junction point of connecting rod 3, junction point between connecting rod and sidesway wheel bar is the 5th node 85 (seeing Fig. 2), and above-mentioned extension spring 7 is located between sidesway wheel bar 2 and connection sliding block 4.Under original state state, extension spring 7 impels sidesway wheel bar 2 near underframe pipe 1, the sidesway wheel 21 that is arranged on sidesway wheel bar end is packed up, trailing wheel (not shown) by wheelchair lands, and now the 3rd node 83 of connection sliding block 4 is positioned at the right side of secondary nodal point 82, the 5th node 85 lines.It is contemplated that, for sidesway wheel 21 is moved downward, realize lateral sliding to replace wheelchair trailing wheel to land, only need to change connection sliding block 4, relative position relation between connecting rod 3 and sidesway wheel bar 2, by the resistance that manually overcomes extension spring 7, impel connection sliding block 4 to move to the left along underframe pipe 1, just will strut sidesway wheel bar 2, the sidesway wheel 21 that drive is arranged on sidesway wheel bar end moves down, replace wheelchair trailing wheel to land, to realize wheelchair shifted laterally, now the 3rd node 83 of connection sliding block 4 will be positioned at secondary nodal point 82, the left side (seeing Fig. 4) of the 5th node 85 lines, and cancel artificial external force, also can keep this state, because although extension spring 7 will impel secondary nodal point 82, the 3rd node 83, the 5th node 85 changes position relationship, but because the wheel of sidesway now 21 lands, ground gives sidesway wheel counteracting force, this counteracting force can be taken turns bar by sidesway and is delivered on connecting rod 3, impel secondary nodal point 82, the 3rd node 83, the 5th node 85 overcomes the effect of extension spring, and keep original position relationship, do not having under other External Force Actings, wheelchair can remain on sidesway wheel 21 state that lands, realize freely sideward sliding function.
In order conveniently to carry out the operation of sideward sliding function, lateral movement mechanism of the present invention is provided with foot control part 5 and hand lever 6.The rod member that above-mentioned foot control part 5 is connected with secondary nodal point 82, the 3rd node 83 respectively for two ends, its end is provided with the pedal 51 of conveniently trampling, by pushes pedals 51, to impel connection sliding block 4 and connecting rod 3 to change position relationship, play the effect of propping up sidesway wheel bar 2, to realize lateral sliding function, equally now the 3rd node 83 of connection sliding block 4 arrives the left side of secondary nodal point 82, the 5th node 85 lines.
Above-mentioned hand lever 6 is rotationally connected with secondary nodal point 82, and between the primary nodal point 81 and the 4th node 84 of connection sliding block, because connection sliding block 4 is to be connected and merged the double-decker forming by connecting pin, so hand lever 6 can be limited between primary nodal point 81 and the connecting pin at the 4th node 84 places.In the time that needs carry out sidesway operation, only need lift hand lever 6, press the connecting pin at primary nodal point 81 places, upset connection sliding block 4, to impel sidesway wheel bar 2 to rotate by connecting rod effect, sidesway wheel 21 replaces wheelchair trailing wheel to land, and realizes lateral sliding, and now the 3rd node 83 of connection sliding block 4 arrives the left side of secondary nodal point 82, the 5th node 85 lines; In the time that needs are regained sidesway and are taken turns 21, only hand lever 6 need be pressed downwards, hand lever is pressed the connecting pin at the 4th node 84 places, upset connection sliding block 4, to impel sidesway wheel bar 2 upwards to rotate by connecting rod effect, wheelchair trailing wheel replaces sidesway wheel 21 again to land, and now the 3rd node 83 of connection sliding block 4 is got back to the right side of secondary nodal point 82, the 5th node 85 lines.
For lateral movement mechanism of the present invention, when pushing away passerby while realizing in the wings lateral sliding function by wheelchair, employing is trampled the pedal 51 of foot control part 5 and is realized sidesway, when needs are replied original wheelchair trailing wheel while landing state, except using hand lever 6 presses downwards, can also firmly lift the rear portion of wheelchair, make sidesway take turns 21 built on stilts, now sidesway wheel loses the support force on ground, the lateral movement mechanism of wheelchair is under the pulling force effect of extension spring 7, to there is relative motion in connection sliding block 4, connecting rod 3, lateral movement mechanism automatically restores to original non-working condition.
See Fig. 6, for the convenient turnover of wheelchair user wheelchair, the handrail design of wheelchair of the present invention is for can open handrail, and handrail and vehicle frame are for being rotationally connected, and handrail is sealed by latch fitting 92 and vehicle frame.In the time that needs are opened handrail, only need to discharge latch fitting 92, and lift the arm-rest frame 91 of handrail, can open handrail, facilitate user to come in and go out; After using, locking latch fitting can restore to the original state.
Obviously, above-mentioned detailed description of the invention of the present invention is only for example of the present invention is clearly described, and is not the restriction to embodiment of the present invention.For those of ordinary skill in the field, can also be easy on the basis of the above description make other pro forma variation or substitute, and these changes or alternative also by within being included in the definite protection domain of the present invention.
