Abstract
An anti-tipping wheel chair comprises an external frame installed together with a chair back and wheels, wherein the external frame is articulated with a seat frame; two outer sides of the seat frame are articulated with a hanging hook and two inner sides of the external frame is provided with a hanging tooth matched with the hanging hook; the acting force of one end of a tension spring acts on the external frame, and the acting force of the other end thereof acts on the seat frame; the external frame is articulated with a lifting pedal and a resetting pedal; the front end of a cranked lever of the lifting pedal is arranged at the lower part of the seat frame; the front end of the cranked lever of the resetting pedal is arranged at the front part of the hanging hook; and the hanging hook is fixed with a hanging spring, the other end of which is fixed on the seat frame. When descending down a slope, the compounded center of gravity of a person and the wheel chair can keep balanced due to the rise of the seat frame, so as not to tip.
Description
Technical field:
This utility model relates to the wheelchair technical field, more specifically to a kind of wheelchair that prevents that wheelchair from toppling in the climb and fall process.
Background technology:
Present wheelchair, seat support can not adjusting angles, and patient is sitting in the wheelchair, and in descending, wheelchair is toppled over because of center of gravity leans forward easily.
The utility model content:
The deficiency that the purpose of this utility model leans forward and topples over because of center of gravity easily when being exactly at the wheelchair descending is anti-ly toppled over wheelchair and provide a kind of, and it is when descending, and center of gravity can be regulated the maintenance balance, can not topple over.
Technology solution of the present utility model is as follows:
Prevent toppling over wheelchair, comprise and the chair back 8, chair wheel 7 outriggers that are installed together 1, on outrigger 1, be hinged with mounting 2, two outsides of mounting 2 are hinged with hook 21, two inboards of outrigger 1 have with the hook 21 match mention 11, extension spring 3 one end active forces in outrigger 1 one end active forces in mounting 2, outrigger 1 is hinged with lifting pedal 4, pedal 5 resets, the curved bar front end 41 of lifting pedal 4 places the bottom of mounting 2, the curved bar front end 51 of pedal 5 of resetting places hook 21 front portions, be fixed with on the hook 21 and hang spring 6, the other end of hanging spring 6 is fixed on the mounting 2.
Be fixed with spring between described lifting pedal 4 and the outrigger 1.
Described resetting is fixed with spring between pedal 5 and the outrigger 1.
Be fixed with wheelchair armrest 9, wheelchair foot-operated 10 on the described outrigger 1.
The beneficial effects of the utility model are:
1, user is sitting on the mounting, and when descending, with foot-operated moving lifting pedal, mounting can upwards rotate around outrigger, be suspended to higher mentioning, during descending, owing to mounting has raise, the composite center of gravity of people and wheelchair just can keep balance, is unlikely to topple over like this.
2, behind the descending, the moving pedal that resets that tramps with one's feet, the pedal that resets will be linked up with from mentioning and back down, and extension spring allows mounting reset to original position again.Whole operation only need gently be stepped on pedal with foot and just can be finished, and the weakling who is fit to be sitting on the wheelchair uses.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
The following stated only is preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model.
See shown in Figure 1: prevent toppling over wheelchair, comprise and the chair back 8, chair wheel 7 outriggers that are installed together 1, on outrigger 1, be hinged with mounting 2, two outsides of mounting 2 are hinged with hook 21, two inboards of outrigger 1 have with the hook 21 match mention 11, extension spring 3 one end active forces in outrigger 1 one end active forces in mounting 2, outrigger 1 is hinged with lifting pedal 4, pedal 5 resets, the curved bar front end 41 of lifting pedal 4 places the bottom of mounting 2, the curved bar front end 51 of pedal 5 of resetting places hook 21 front portions, be fixed with on the hook 21 and hang spring 6, the other end of hanging spring 6 is fixed on the mounting 2.
Be fixed with spring between described lifting pedal 4 and the outrigger 1.This is the elastic sensation in order to increase pedal and to trample.
Described resetting is fixed with spring between pedal 5 and the outrigger 1.
Be fixed with wheelchair armrest 9, wheelchair foot-operated 10 on the described outrigger 1.
Operation principle: user is sitting on the mounting 2, when descending, with foot-operated moving lifting pedal 4, the curved bar front end 41 of lifting pedal 4 will upwards rotate mounting 2 around outrigger 1, hook 21 is suspended to higher mentioning on 11, like this during descending, owing to mounting 2 has raise, the composite center of gravity of people and wheelchair just can keep balance, is unlikely to topple over.
Behind the descending, the moving pedal 5 that resets that tramps with one's feet, the pedal 5 that resets will link up with 21 from mentioning that 11 back down, and extension spring 3 allows mounting 2 reset to original position again.Whole operation only need gently be stepped on pedal 4,5 with foot and just can be finished, and the weakling who is fit to be sitting on the wheelchair uses.
Hang spring 6 and be in order to link up with 21 and can stabilization energies hang over and mention on 11, just keeping link up with 21 fixed positions on mounting 2, be suspended to when mentioning on 11, do not give and link up with pressure at hook 21.To link up with 21 from mentioning 11 when backing down when the pedal 5 that resets, mounting 2 just can no longer be subjected to linking up with 11 power, and resets under the pulling force of extension spring 3.
