Improved wheelchair

Abstract

The invention provides an improved wheelchair. The technical scheme is as follows: the improved wheelchair comprises a wheelchair frame, a sliding channel, a sliding base and a chair, wherein the sliding channel comprises a first platform, a second platform and a third platform which are connected in sequence, two sides of each of the first platform, the second platform and the third platform areprovided with two baffle walls with inner side walls sinking inwards to form positioning grooves, a connecting rod is arranged on the upper surface of the second platform, and the first platform and the third platform are provided with two upper buckling bases for clamping of the connecting rod in a manner of corresponding to the front and rear ends of the connecting rod; a universal bead allowingthe sliding base to slide among the first platform, the second platform and the third platform is arranged at each of four corners of the bottom end of the sliding base; and two armrest structures capable of being folded towards the forward direction are arranged on two sides of the chair, and a back cushion is arranged between the armrest structures. Therefore, a caretaker can assist a person having moving difficulty in moving between the wheelchair and a car seat, and thus the person having moving difficulty can be moved for getting on and off a vehicle in a more steady and safer manner.

Description

technical field [0001] The invention relates to the technical field of wheelchairs, in particular to an improved wheelchair that can be connected with a car seat so that a caregiver can easily move a handicapped person to the car seat. Background technique [0002] People with disabilities generally need wheelchairs and other tools to assist them when they go out because they are not good at moving. Except that the bus itself has lifting equipment for wheelchairs, ordinary vehicles cannot be equipped with such lifting equipment. Therefore, a lateral-moving mobile equipment has been invented, which can move people with disabilities from wheelchairs to the rear seats of vehicles , but there is a height difference between the compartment floor and the ground, so it is not easy to move horizontally, so the caregiver still needs to hold it with both hands to move, so it is difficult and difficult for people with limited mobility to get on and off the car. Not only will it cause ...

AI Technical Summary

Problems solved by technology

[0004] 1. From the patent image 3 and Figure 7 It can be seen that the armrest structure is in a flat state when the second slide rail is connected to the first slide rail. Therefore, during the sliding process, there is no handrail or support for people with disabilities around the cushion structure. The back of the seat, in this way, if there is a slight shake when sliding, it will cause the danger of the occupant falling from the cushion structure, so it is necessary to improve

[0005] 2. From the patent image 3 and Figure 5 It can be seen from the figure that when the first slide rail and the second slide rail are connected to each other, the lower part of the connecting section is in a suspended state. After long-term use, the connecting section is easily bent and deformed. When the seat cushion structure slides to the connecting section, it may get stuck or slide unsmoothly, and in serious cases, it may even cause the risk of breaking, causing riding hazards

[0006] 3. The wheelchair cannot be moved up and down. If it is a taller vehicle, such as a recreational vehicle, station wagon, etc., it still needs to be carried by a caregiver to move, which is obviously not practical.

[0007] 4. The cushion structure cannot be fixed with the seat in the car, so when the car is moving, the cushion structure is prone to displacement, causing riding hazards

[0008] 5. Between the cushion structure and the car seat, there is no device that facilitates the sliding of the cushion structure to the wheelchair. Therefore, when the cushion structure needs to slide from the car seat to the wheelchair, it will be affected by the weight of the occupant. As a result, the cushion structure becomes extremely heavy and difficult to move, causing inconvenience and trouble in use
