Abstract
The utility model relates to a wheel chair which can climb steps and belongs to a wheel chair, in particular to a wheel chair which enables a patient who has lower-limb disability and lower-limb inability to climb steps by utilizing the force of the upper limbs. The wheel chair comprises a front wheel 2, rear wheels 1 and a seat chair, and also comprises a supporting mechanism composed of rotating legs 7, a bracket 4 and a rocker 10. The middle section of the bracket 4 is provided with an axle hole and is arranged on a main shaft 6 of the front wheel; the lower end of the bracket, the rotating center of the rotating legs and the lower end of the rocker are hinged through a pin roll 8; and a ratchet wheel is adopted for transmission between the lower end of the rocker and the rotating legs. When the wheel chair passes through steps, only the rocker 10 is needed to be swung continuously, then the rotating legs are driven to directionally rotate through the transmission of the ratchet wheel so as to support the front wheel upwards, and the wheel chair can be driven to the forward steps. The utility model has the advantages of simple, portable and flexible structure and convenient operation.
Description
Technical field
This utility model belongs to a kind of wheelchair, particularly relates to a kind of confession lower limb disability and weakness of the lower extremities patient and utilizes upper limbs force to realize climbing up the wheelchair of step.
Background technology
In the prior art, common wheelchair light and flexible is for lower limb disability and weakness of the lower extremities patient provide many convenience.But, at stair activity or when coming in and going out the various place that step arranged, then need other people to help, effort very, inconvenience.In the patent formerly, as No. 2004200027097 patents, disclose a kind of " hand stair-climbing wheel chair ", comprised disjunctor seat, driven by shaking mechanism, front-wheel and trailing wheel, also comprised creeper undercarriage, seat elevating mechanism, trailing wheel cantilever link gear and trailing wheel lifting link-gear.Its drawback is complex structure, the cost of manufacture height, and inconvenient operation, and heaviness is not nimble when normal road traveling.
Summary of the invention
The purpose of this utility model promptly is to provide a kind of novel rank stepped on wheelchair, can climb up step and purpose simple in structure, light and flexible to reach.
The rank wheelchair of stepping on disclosed in the utility model comprises front-wheel 2, trailing wheel 1 and seat 3, it is characterized in that, also comprises the supporting mechanism of being made up of swing leg 7, support 4 and rocking bar 10; There is axis hole in the stage casing of support 4, is installed on the main shaft 6 of front-wheel; The lower end of support, realize hingedly by bearing pin 8 with the lower end of the center of rotation of swing leg and rocking bar, the lower end of rocking bar and swing leg adopt the ratchet transmission between the two, and promptly there is ratchet the lower end of rocking bar, cooperates with the ratchet of ratchet on the swing leg 9; Between the epimere and seat of support, realize fixing by the alignment pin of locating hole 5 and cooperation with it.
The rank wheelchair of stepping on disclosed in the utility model, comprise the supporting mechanism of forming by swing leg 7, support 4 and rocking bar 10, during by step, only need constantly swing rocking bar 10, can drive the directed rotation of swing leg by the ratchet transmission, thereby front-wheel is supported, can drive towards the step of front.At prevailing roadway, only need support 4 is positioned at horizontal level, can normally travel.This shows, the utlity model has simple in structure, light and flexible, easy to operate good effect.
Description of drawings
The accompanying drawing part further discloses specific embodiment of the utility model, wherein:
Fig. 1, this utility model schematic top plan view;
Fig. 2, this utility model front elevational schematic;
Fig. 3, this utility model application state reference diagram.
The specific embodiment
As shown in Figure 1, the rank wheelchair of stepping on disclosed in the utility model, agent structure is identical with common wheelchair, promptly comprises the seat 3 of two front-wheels 2, trailing wheel 1 and middle part.
As shown in Figure 2, this utility model also comprises the supporting mechanism of being made up of swing leg 7, support 4 and rocking bar 10.There is axis hole in the stage casing of support 4, is installed on the main shaft 6 of front-wheel, can rotate.Between the epimere and seat of support, the alignment pin that is provided with two locating holes 5 and cooperates with it is to realize the fixed angle of support in level or upright position respectively.The lower end of support, realize hinged by bearing pin 8 with the lower end of the center of rotation of swing leg and rocking bar.There is ratchet the lower end of rocking bar, cooperate with the ratchet of ratchet on the swing leg 9, thereby the ratchet transmission between formation rocking bar and the swing leg constantly swing rocking bar, but the driven rotary supporting leg is made folk prescription to rotation.Because the ratchet transmission is the kind of drive of using always, expects easily and can realize, so do not do too much explanation.
As shown in Figure 3, this utility model is when crossing over step, the support 4 of supporting mechanism is adjusted into vertically, and utilize the alignment pin of locating hole 5 and cooperation with it to be fixed on the seat main body, swing rocking bar 10 then, the ratchet of ratchet 9 interacts on ratchet by its lower end and the swing leg, and the driven rotary supporting leg is directed to rotate, thereby front-wheel is supported, can drive towards the step of front.At prevailing roadway, as shown in Figure 2, only need support 4 is positioned at horizontal level, can normally travel.
