Abstract

The present invention is an invention equipped with a function that helps the user to move to the bed smoothly and safely by directly manipulating the wheelchair. For example, a patient with impaired leg mobility can move to the bed with minimal movement of the upper body. In addition, it is as safe as or safer than the conventional wheelchair by using a kinematic mechanism.

Description

Bed-move assistant wheelchair {bed-move assistant}

The present invention allows the elderly and patients with mobility difficulties to move to the bed conveniently, allows the user to move to the bed with minimal motion while sitting, and has a leg angle adjustment function. Also, it relates to an assistive device (wheelchair) for a patient with reduced mobility as a wheelchair in which the user can actively operate the wheelchair without the help of others.

Wheelchairs are designed so that patients or the elderly can move without moving when they move somewhere. Generally, wheels are formed in the shape of a chair so that the patient can be seated so that it can be moved forward at the bottom of both sides next to the seat, and the handle is formed at the shoulder level of the patient on the dorsal side, so that the patient can be more easily gripped and dragged or pushed used to move There are several other forms depending on the purpose. Among these various types of wheelchairs, the seat on which the patient sits rises to help the patient stand up and facilitates blood circulation, and since each patient has a different body, the height is adjusted to fit the patient and moves to a higher position than before. there is a wheelchair

However, these wheelchairs can only move the patient from a seated state to a higher place, and are not helpful when the patient needs to move to a bed or other place. In addition, a wheelchair having a function of lateral movement is presented in Patent Publication 10-2018-0104432, but the user cannot control it directly.

There are caregivers or nurses to move the wheelchair user to the bed, but the actual discomfort felt by the user is psychologically great, and the caregiver or nurse is also insufficient to safely move the patient to the bed by themselves. Therefore, in order to solve this problem, a patient in a wheelchair can be moved to a bed, and there is a need for a wheelchair that can move the patient to the bed in the most stable posture without discomfort.

Since the present invention can adjust the height, the height at which the patient can easily move to the bed is adjusted, and the slide function is also included to reduce the gap between the wheelchair and the bed.

In order to solve the above problem, there are three core functions that must be included in a wheelchair. First, it must be possible to adjust the height. To enable height adjustment, an x-shaped structure is installed at the bottom of the wheelchair seat to adjust the height using an electric cylinder 301, and to adjust the angle of the leg seat frame 5 The electric cylinder 203 is connected. Finally, in order to enable lateral movement of the wheelchair seat, a rail used for furniture such as drawers is used to connect the connecting part of the seat upper plate 101 and the seat lower plate 102 with a rail, and then the seat upper plate 1 and the seat By installing the driving unit 104 in the space between the lower plates 2, the lateral movement of the upper plate seat on which the user directly sits is possible as much as the movement of the electric cylinder stroke.

According to the present invention, the user using a wheelchair can complete the cumbersome process that previously had to move to the bed with the help of others, without the help of others, and the user's discomfort and manpower felt in the process of moving to the bed Consumption (caregivers, nurses) can be reduced.

Figure 3 is a front view of the wheelchair of the present invention. Figure 4 is a perspective view when the height adjustment function, the slide function, and the leg seat angle adjustment function are all used. 5 is a right side view of a wheelchair that does not use the chair function of the present invention.

Referring to FIG. 1 , the present invention is largely composed of a seat part 100 , a height adjustment part 200 , and a lower part 300 .

When the user boards, that is, when no function is used, first, the height of the x-shaped structures 202 and 201 in a state where the stroke length of the height adjustment electric cylinder 301, which is the driving part of the height adjustment unit 200, is minimized. is the lowest, and the leg seat 103 also maintains the initial angle, and there is no change in the driving unit 104 that controls the slide function (refer to FIG. 2).

After the user boards, the state after using the height-adjustable electric cylinder 301 is that the electric cylinder 301 pushes the x-shaped inner structure 202, so that the x-shaped structures 202 and 201 are part of the lower plate 302. You can adjust the height by sliding in. In addition, a guide 303 is installed to prevent the patient from feeling anxious due to vibration or play when the height is adjusted. (See Fig. 3)

After the height of the wheelchair is adjusted, the angle of the leg seat is adjusted so that the user's legs are also adjusted to the desired height. At this time, the electric cylinder 203 for adjusting the angle of the leg seat is driven, and the electric cylinder for adjusting the angle of the leg seat 203 is connected by a bracket hanging under the lower seat 102 to adjust the height of the leg seat independently even when the height of the leg seat rises. The angle of the leg seat 103 can be adjusted (see Fig. 4).

As the last stage of the present invention, a guide is needed to move the seat with a small force when the driving unit makes a linear motion for lateral movement. This guide is not limited to the rail used in the example of the present invention. It should be interpreted as an auxiliary aid in linear motion (refer to Fig. 5).
