Description

Improved wheelchair

The present invention relates to the technical field of wheelchairs, and more particularly to an improved wheelchair that can be coupled to a car seat to facilitate the caregiver to shift a person with reduced mobility to the car seat.

In modern society, it is very convenient to take long-distance travel by car. Because people with reduced mobility are more difficult or unable to walk freely, it is necessary to go out to a place far away and cannot rely on wheelchairs and other auxiliary tools. When arriving, people with reduced mobility can only use vehicles such as cars, vans or Rehabus as the main means of transportation. However, except for the general vehicles other than Rehabus, there is a difference in height between the floor and the ground. People, it is very difficult and painful to get on and off the vehicle by themselves. It is usually necessary to rely on the caregiver to hug and move. This will not only cause the burden on the caregiver, but also easily lead to people with reduced mobility during the movement. Discomfort or further injury.

Therefore, in view of the above problems, there is a research and development by the industry, as shown in Taiwan Patent Publication No. M494603, which is a "wheelchair for a vehicle having a sliding cushion structure", which includes: a base provided with a first slide rail And a bottom surface of the base is further provided with a plurality of wheels; a seat cushion structure is provided with a sliding member corresponding to the first sliding rail; and two armrest structures are disposed on two opposite sides of the base, the two armrest structures The at least one armrest structure includes an armrest and a second slide rail disposed on the armrest, the second slide rail is movably connected to the base, and the second slide rail is movable relative to the base, so that the first The two slide rails can be coupled to the first slide rail to form a complete slide rail for the slider of the seat cushion structure to slide between the first slide rail and the second slide rail. Although the patent pre-existing case reveals the role of people who can move and move inconveniently, it is found that there are still problems in the actual use of the creator: 1. As can be seen from Figure 3 and Figure 7, the patent case The armrest structure is in a flat state when the second sliding rail is connected with the first sliding rail. Therefore, during the sliding process, there is no armrest or backrest supported by the person with limited mobility around the cushion structure. As a result, if there is a slight shaking during the slippage, the risk of the occupant falling off the cushion structure is necessary to improve. 2, as can be seen from FIG. 3 and FIG. 5, when the first slide rail and the second slide rail of the prior patent are connected to each other, wherein the lower portion of the connecting section is in a state of being suspended, which is used for a long time, The connecting section is easily bent and deformed, and as a result, the cushion structure may slip to the connecting section, and the jamming or slipping may not occur smoothly. Moreover, in severe cases, even a crack may occur, thereby causing a situation. Danger when riding. 3. The wheelchair in the previous case cannot be moved up and down. If it is a higher vehicle, such as a recreational vehicle or a station wagon, it still needs to rely on the caregiver to hug and move. The practicality is obviously insufficient. 4. The seat cushion structure of the prior patent cannot be fixed with the seat in the automobile. Therefore, when the car is traveling, the seat cushion structure is prone to displacement, thereby causing danger when riding. 5. The seat structure of the patent case and the car seat are not provided with any device that facilitates the slipping of the seat cushion structure to the wheelchair. Therefore, when the seat cushion structure needs to be slipped from the car seat to the wheelchair, Due to the weight of the occupant, the cushion structure becomes extremely heavy and difficult to move, causing inconvenience and trouble in use.

In view of this, how to improve the above-mentioned problems and develop an improved wheelchair that can be used for people with reduced mobility to get on and off various types of vehicles and have high safety has become the idea and research topic of the creators of the present invention.
