Description

The folding walking aid

This utility model belongs to nursing apparatus, particularly a kind of folding walking aid.

Based on the demand that places, carries, the walking aid of generally commonly using is all can reduced form.As shown in Figure 6, the walking aid of commonly using comprise the front wheel carrier that is provided with front-wheel, with front wheel carrier articulate and be provided with trailing wheel rear wheel frame, be located at the front wheel carrier upper end upper holder, be located at the upper holder top and have the handle bridge of handlebar stem and be hubbed to be between forward and backward wheel carrier and articulate shape and can relative reduced folded piece.When folding, be to pull the folding upper holder toward the front side, make the handle bridge of upper holder be placed in front wheel carrier, and folding is by folded piece, make front and rear wheel relatively by moving, and reach collapse state.This form that folds, because of being provided with the multistage folding structure, not only structure and complicated operation, and the front and rear wheel of front and rear wheel is set up in very lower and fixing with the folded piece support at this place of car body, if desire is received forward, trailing wheel, user must bend folded piece by manual mode by low body, can and close front and rear wheel and forward and backward wheel carrier, causes quite inconvenience of operator scheme.

The purpose of this utility model provides a kind of simple in structure, easy to operate, folding walking aid that serviceability is good.

This utility model comprises front wheel carrier, rear wheel frame, chair plate, location-plate and connecting rod; The nearly centre of front wheel carrier sets firmly the pivot seat, and its bottom is pivoted with front-wheel, establishes the holder of tool pin rod between pivot seat and front-wheel; Rear wheel frame top level forward extends seat pole, and its bottom is pivoted with trailing wheel; The front end of location-plate be provided with the front wheel carrier holder on the corresponding chute of pin rod, the chute two ends form recess; Rear wheel frame is articulated on the pivot seat of front wheel carrier with its upper end; The chair plate is on the seat pole that the shape pivot of can throwing is connected in rear wheel frame with its front end, and the location-plate front end is located at the pin rod of front wheel carrier holder with its chute slip cap, and the rear end of location-plate is hubbed at the rear wheel frame middle part; The connecting rod two ends articulate with chair plate rear end and location-plate front end respectively.

Because this utility model comprises rear wheel frame, chair plate, location-plate and the connecting rod of the front wheel carrier of the front-wheel that is pivoted, the trailing wheel that is pivoted; The nearly centre of front wheel carrier sets firmly the pivot seat, establishes the holder of tool pin rod between pivot seat and front-wheel; Rear wheel frame top level forward extends seat pole; The front end of location-plate is provided with the chute that two ends form recess; Rear wheel frame is articulated on the pivot seat of front wheel carrier with its upper end; The chair plate is on the seat pole that the shape pivot of can throwing is connected in rear wheel frame with its front end, and the location-plate front end is located at the pin rod of front wheel carrier holder with its chute slip cap, and the rear end of location-plate is hubbed at the rear wheel frame middle part; The connecting rod two ends articulate with chair plate rear end and location-plate front end respectively.When Zhan Li uses, the relative front wheel carrier of rear wheel frame is a center deployment with the pivot seat, and make the seat pole of chair plate flat cover in rear wheel frame, be snapped on the pin rod of front wheel carrier holder by location-plate front end chute front end recess, with the start point of fixing forward and backward wheel carrier, and by two ends respectively the pivot connecting rod restriction location-plate that is connected in chair plate rear end and location-plate front end keep the buckle of its upper notch and pin rod; When folding, move by pulling continuously to draw on the chair plate rear end, its recess that promptly drives location-plate upper hopper chute front end with connecting rod breaks away from the pin rod of holder earlier and rises along the pin rod slippage, and it is that pivot point is rotated towards front wheel carrier with the pivot seat that the rear wheel frame seat support pole that articulates with the chair front edge of board also drives rear wheel frame; Be against on the front wheel carrier until the rear wheel frame receipts, and make the pin rod of holder support the rear end that terminates in the location-plate chute; Put slightly then from the chair plate, location-plate upper hopper chute rear end recess is snapped in pin rod and folds state to fix it, fold action link up, rationally, coordinate, not only simple in structure, easy to operate, and serviceability is good, thus reach the purpose of this utility model.

Below in conjunction with accompanying drawing this utility model is further elaborated.

As shown in Figure 1, this utility model comprises front wheel carrier 1, rear wheel frame 2, chair plate 3, location-plate 4 and connecting rod 5.

Front wheel carrier 1 nearly centre sets firmly pivot seat 11, and its bottom is pivoted with front-wheel 10, establishes the holder 12 of tool pin rod 121 between pivot seat 11 and front-wheel 10.

Rear wheel frame 2 tops level forward extend seat pole 21, and its bottom is pivoted with trailing wheel 22.

The front end of location-plate 4 be provided with front wheel carrier 1 holder 12 on pin rod 121 corresponding chutes 41, chute 41 two ends form recess 411,412.

Rear wheel frame 2 is articulated on the pivot seat 11 of front wheel carrier 1 with its upper end; Chair plate 3 is on the seat pole 21 that the shape pivot of can throwing is connected in rear wheel frame 2 with its front end, and to constitute the tool seat of having a rest, location-plate 4 front ends are located on the pin rod 121 of front wheel carrier 1 holder 12 with its chute 41 slip caps, and the rear end of location-plate 4 is hubbed at rear wheel frame 2 middle parts; Connecting rod 5 two ends articulate with chair plate 3 rear ends and location-plate 4 front ends respectively.

As shown in Figure 1, this utility model exhibition is stood when using, rear wheel frame 2 relative front wheel carriers 1 are center deployment with pivot seat 11, and make chair plate 3 flat covers on the seat pole 21 of rear wheel frame 2, be snapped on the pin rod 121 of front wheel carrier 1 holder 12 by location-plate 4 front end chutes 41 front end recesses 411, with the start point of fixing forward and backward wheel carrier 1,2, and by two ends respectively the pivot connecting rod 5 restriction location-plates 4 that are connected in chair plate 3 rear ends and location-plate 4 front ends keep the buckle of its upper notch 411 and pin rod 121.

When desiring to fold this utility model, at first, as shown in Figure 2, move by pulling to draw on chair plate 3 rear ends, it promptly drives the pin rod 121 of the recess 411 elder generations disengaging holder 12 of location-plate 4 upper hopper chutes 41 front ends with connecting rod 5; As shown in Figure 3, chair plate 3 continues to pull to pull on and moves, and location-plate 4 upper hopper chutes 41 rise along pin rod 121 slippages, and at this moment, it be that pivot point is towards front wheel carrier 1 rotation with pivot seat 11 that the rear wheel frame 2 seat support poles 21 that articulate with chair plate 3 front ends also drive rear wheel frame 2; As shown in Figure 4, be against on the front wheel carrier 1, and make the pin rod 121 of holder 12 support the rear end that terminates in location-plate 4 chutes 41 until rear wheel frame 2 receipts; As shown in Figure 5, put slightly from chair plate 3, location-plate 4 upper hopper chutes 41 rear end recesses 412 are snapped in pin rod 121 and fold state to fix it.

In sum, this utility model folds coherent, reasonable, the convenience of coordinating, take down the exhibits of action.
