Description
Technical field
This utility model relates to a kind of wheelchair, especially can realize the apparatus for ride instead of walk that the basic function with wheelchair combines with the basic function of crutch.
Background technology
Wheelchair is most cripples and the selected apparatus for ride instead of walk of the residual personage of old body.Yet, when meeting the situation that needs to climb stair or cross over roadblock, common manual, electric wheelchair all can do nothing to help user and solve these situations, and more already present wheelchair kind with stair climbing function is numerous on the market, climb the type of building actuator according to the stair climbing device, mainly can be summed up as wheels formula, crawler type, lower limb formula three classes, but these wheelchair volumes are comparatively huge, the difficulty that operates is bigger.Crutch is the same with wheelchair to be apparatus for ride instead of walk indispensable in the residual personage's daily life of cripple and old body, but the purposes difference that crutch stresses.In this case, designing can be with the advantages of the advantage of wheelchair and crutch Wheelchair structure together, thereby makes the wheelchair user can realize speeling stairway more independent, more easily, cross over roadblock, will have higher using value and practical significance.
The utility model content
This utility model can't well help user to finish the problem of climbing stair or leap roadblock in order to overcome the wheelchair that has common wheelchair now and have the stair climbing function, utilize the characteristic of the special upset of rod member, it is the wheelchair of crutch that a kind of deformable is provided, this wheelchair is the advantages structure together with the advantage of wheelchair and crutch, user can be deformed into crutch with wheelchair by simple deformation operation, perhaps crutch is deformed into wheelchair, makes user can realize speeling stairway more independent, more easily, cross over roadblock.
Deformable among the application is that the wheelchair of crutch comprises scissors supporting construction, band driving structure, folding pedals structure, medicated cushion 1, the backrest 4 that band seesaws and takes turns, and band driving structure, folding pedals structure, medicated cushion 1 and backrest 4 are fixed on the scissors supporting construction of being with the wheel that seesaws.
The scissors supporting construction that seesaws wheel described in the utility model comprises front wheel bar 2, rear wheel bar 3, front-wheel 12, trailing wheel 9, front fork 13, front-wheel fixed bar 16, front wheel bar 2 and rear wheel bar 3 constitute main body supporting structure, trailing wheel 9 is installed on the rear wheel bar 3 by being threaded, front-wheel 12 is installed on the front fork 13, front fork 13 is hinged on the front wheel bar 2, and is fixed on the front wheel bar 2 by front-wheel fixed bar 16.
Band driving structure described in the utility model comprises small pulley 6, big belt wheel 10, belt 8, driving handle 7, wherein small pulley 6 is fixed on the rear wheel bar 3, big belt wheel 10 is fixed on the trailing wheel 9, and belt 8 is enclosed within on small pulley 6 and the big belt wheel 10, and driving handle 7 is arranged on the small pulley 6.
Folding pedals structure described in the utility model comprises brace 17, pedal connecting rod 15, pedal strut 11, pedal 14, brace 17 is hinged on the front wheel bar 2, pedal connecting rod 15 is hinged on the brace 17, pedal strut 11 inserts pedal connecting rod 15 and its slip relatively, and pedal 14 is hinged on the pedal strut 11.
When brace 17 rotates relative to front wheel bar 2, can drive pedal connecting rod 15 and pedal strut 11 and rotate so that wheelchair when being deformed into crutch the folding pedals structure can with front wheel bar 2 point-blank.When folding pedals arrangement works during at the wheelchair state, the structure utilization is the operation principle at " dead point " mechanically, makes that this structure is indeformable; When folding pedals arrangement works during at the crutch state, the two ends of pedal connecting rod 15 are stuck on the draw-in groove of reserving on the front wheel bar 2, make that crutch can steady operation.
Have handrail 5 on the backrest 4 described in the utility model.
This utility model wheelchair can be with scissors supporting construction, band driving structure, folding pedals structure, medicated cushion 1 and the backrest 4 of the wheel that seesaws to form by symmetrical two covers, and by the fixing symmetrical two parts of connector, user can separately form two crutch with left and right sides two parts by the state that changes connector.
This deformable is that the remainder connection of the wheelchair of crutch connects into basic building block the works that can bear external applied load by rivet or bolt.
When this device was out of shape to crutch by wheelchair, the connector with the left-right symmetric parts separated earlier, and takes apart, and the medicated cushion 1 with a left side half wheelchair or right half wheelchair separates with backrest 4 then, and adjustable plate 18 top nuts are unscrewed, and backrest 4 and front wheel bar 2 can be relatively rotated; Fixedly front wheel bar 2 is motionless, backrest 4 rotates 75 ° relative to front wheel bar 2 clockwise (right half part is for clockwise), rear wheel bar 3 clockwise rotated around the intersection point of front wheel bar 2 and rear wheel bar 3 make the two point-blank (keep this moment medicated cushion 1 and rear wheel bar 3 angles constant), fixedly rear wheel bar 3 is motionless, adjust the relative position of medicated cushion 1 and rear wheel bar 3, make the two at straight line; Adjust the angle of pedal 14 and front fork 13 at last, can obtain crutch.
This utility model utilizes the characteristic of the special upset of rod member, realizes wheelchair is deformed into crutch, has solved the situation that traditional push chairs can not help user to climb stair or cross over roadblock.Designed deformable is that the wheelchair of crutch can be operated in two kinds of different states, i.e. wheelchair state and crutch state according to the needs of user.This utility model acquiescence is operated in the wheelchair state, when needs are used crutch, user can rely on self or other people with each rod member process certain deformation, realize that each rod member is integrated on the straight line, and make it to finish after fixing change from the wheelchair to the crutch, and can be wheelchair by opposite course recovery.Need not to remove any parts in the deformation process, only need to realize mutual transformation between wheelchair, crutch to the adjustment that each rod member in the wheelchair carries out certain angle.
This utility model at existing common wheelchair can't the help user finish the practical situation of climbing stair or crossing over roadblock, characteristic according to the special upset of rod member, designing deformable is the wheelchair model of crutch, can be with the advantages of the advantage of wheelchair and crutch together, make user can realize speeling stairway more independent, more easily, cross over roadblock, have higher using value and practical significance.And deformation process is simple, and user can be finished deformation operation voluntarily or under other people help, and the scope of application of improving existing common wheelchair, expansion wheelchair is significant and practical value.
