Abstract
The utility model discloses the wheelchairs turned over after a kind of prevent, including wheelchair frame, front-wheel and rear-wheel, handrail, cushion and backrest are provided on wheelchair frame, it is characterized by also including an anti-rear focusing devices, the device includes bracket and idler wheel, riding setting, one end of bracket and wheelchair frame are connected and fixed by horizontal rotating shaft, idler wheel is located at the other end of bracket, and the vertical range of any point to rear axis line is all larger than the radius of rear-wheel on idler wheel, and idler wheel is located at the rear of rear-wheel.When wheelchair is toppled over backward, the idler wheel being located behind can contact ground, so that wheelchair continuation be prevented to topple over backward.
Description
Technical field
The utility model relates to wheelchair technical fields, and in particular to a kind of wheelchair for preventing from toppling over backward.
Background technique
Currently, wheelchair is the important tool of rehabilitation, it is not only the walking-replacing tool of limbs the disabled and people with mobility problems,
Them are more importantly made to carry out physical exercise by means of wheelchair and participate in social activities.Common wheelchair is generally by wheelchair frame, vehicle
Wheel, brake gear and seat against four parts composition.
Since the user of wheelchair is mostly old man or handicapped person, when improper use, it is more likely that cause to take turns
It turns over after chair, therefore is turned over after how preventing wheelchair, be the theme to be studied of this patent.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of wheelchairs for preventing from translating into backward.
In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model are as follows: it is a kind of prevent after the wheelchair that turns over, packet
Wheelchair frame, front-wheel and rear-wheel are included, handrail, cushion and backrest are provided on wheelchair frame, it is characterised in that: further include
One anti-rear focusing device, the device include bracket and idler wheel, and riding setting, one end of bracket and wheelchair frame pass through level
Shaft is connected and fixed, and idler wheel is located at the other end of bracket, and on idler wheel any point to rear axis line vertical range it is equal
Greater than the radius of rear-wheel, and idler wheel is located at the rear of rear-wheel.
Further, the anti-rear focusing device further includes damping spring, and damping spring one end is fixed on wheelchair frame, separately
One end is connect with bracket, and tie point and idler wheel are located at the same side of horizontal rotating shaft, and bracket can be rotated around trunnion axis.
Further, the bottom level difference of the bottom of the idler wheel and rear-wheel is 10~15cm.
Further, the backrest includes a U-tube body and harness, and described harness one end is fixed on U-tube body
Side, the other end cross the removable connection of another side with harness after the other side bending of U-tube body.
From above-mentioned technical proposal it can be seen that the utility model has the advantage that when wheelchair is toppled over backward, after being located at
The idler wheel of side can contact ground, so that wheelchair continuation be prevented to topple over backward, damping spring can not only play cushioning effect, may be used also
To play buffer function to holder pivots, bracket damage is reduced.The bottom of idler wheel and the bottom level difference of rear-wheel can limit wheel
The sweptback angle of chair.The lateral length of harness is adjusted to adapt to the back of hunchback.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
A specific embodiment of the invention is illustrated below in conjunction with attached drawing.
As shown in Figure 1, the wheelchair fallen after the preventing of the utility model, including wheelchair frame 6, front-wheel 4 and rear-wheel 5,
Handrail 1, cushion and backrest 2 are provided on wheelchair frame.If it is electric wheelchair, wheelchair frame be also used to dispose storage battery and
Motor etc., wheelchair frame are mainly that each component provides support and fixes.
The utility model is equipped with including an anti-rear focusing device, is also applied for electric wheelchair suitable for manual wheelchair.It should
Device includes bracket 8 and idler wheel 9, and bracket 8 is obliquely installed.One end of bracket 8 is connect with wheelchair frame 6 by horizontal rotating shaft solid
Fixed, idler wheel 9 is located at the other end of bracket 8, and the vertical range of any point to rear axis line is all larger than rear-wheel on idler wheel 9
Radius, and idler wheel 9 is located at the rear of rear-wheel.When wheelchair is toppled over backward, the idler wheel being located behind can contact ground, to hinder
Only wheelchair continuation is toppled over backward.
Focusing device further includes damping spring 7 after anti-, and 7 one end of damping spring is fixed on wheelchair frame, the other end and bracket
Connection, and tie point and idler wheel are located at the same side of horizontal rotating shaft, bracket can be rotated around trunnion axis.Damping spring can not only rise
To cushioning effect, can also holder pivots be played with buffer function, reduce bracket damage.The bottom of idler wheel and the bottom of rear-wheel are high
Degree difference is 10~15cm, can limit the sweptback angle of wheelchair by difference in height.
In order to adapt to the old man of some hunchbacks, it is provided with such as flowering structure.The backrest includes a U-tube body and harness
3, described 3 one end of harness is fixed on the side of U-tube body, and the other side that the other end crosses U-tube body is another with harness after bending
Removable connection on one side, such as use velcro, button form.By adjust harness lateral length to adapt to hunchback after
Back.
