Description

The present invention relates to a wheelchair stair elevating device in which a person requiring long-term care who is in a wheelchair in the event of a fire, flood, disaster, etc. is placed on the elevating device together with the wheelchair by one caregiver and safely descends or ascends the stairs.

For ascending and descending stairs, electric rail type and battery type electric lifting device in which the caregiver stands behind the care recipient are known.

The electric type cannot go up and down the stairs in the event of a power outage or a low battery.
Of course, it is possible to go up and down in normal times, but since the conventional stair lift device keeps the wheelchair horizontal, the person requiring long-term care is farther and higher than the stair surface. As a result, I feel a sense of fear.
In addition, the caregiver who always operates the elevating device is at the upper part of the stairs, and the elevating device obstructs the visual observation and it is difficult to see the downstairs.

Means to try to solve the problem

When descending the stairs, as shown in Fig. 1, the care recipient gets on a wheelchair so that the upper part of the stairs can be seen and is safely fixed, and the caregiver is at the bottom of the device and descends the stairs while visually observing the front. It is safe to see your feet well, and the care recipient has a great sense of security.

When ascending the stairs, as shown in FIG. 2, the care recipient gets on a wheelchair so that the upper part of the stairs can be seen and is safely fixed.

As shown in FIG. 6, after the slope when the wheelchair gets on the trolley deck is completed, it becomes an upright wall with a hinge and can prevent the falling object from hitting the care recipient when going up and down the stairs or in the event of a disaster. In addition, by facing the risk of falling and the caregiver, it is no longer possible to look downstairs, and it is felt that the person is protected from the fear of moving.

The invention's effect

1. 1. The care recipient is on the stairs, at a low position, and there is a caregiver behind (the lower part of the stairs), so there is a great sense of security.
2. 2. When descending, the caregiver is safe because he / she can look forward and look at his / her feet.
3. 3. When climbing, the caregiver faces upward and can climb while checking the condition of the care recipient, so it is safe.
4. Since the slope when getting in a wheelchair becomes an upright wall after getting in, it is possible to avoid a direct hit to the care recipient from an unexpected situation such as a falling object when going up and down. In addition, the care recipient will be in a position to look upstairs when descending, and by not looking downstairs, he will not look downstairs and feel the fear of falling.
5. The device is compact and inexpensive because it moves up and down manually.

Hereinafter, embodiments of the present invention will be described.

1. 1. A pair of left and right sleds (3) or a belt conveyor (24) are provided on the side plates (6) connected by the stay. The lower part of the sled and the belt conveyor is pressurized by a spring (4) whose pressure can be adjusted.
2. 2. A pair of columns (12) are erected from the tip of the side plate.
3. 3. A pair of handles (13) and a brake lever (14) orthogonal to the support column are provided.
4. When descending the stairs, the caregiver (12) grasps the handle and the brake lever and descends the stairs.
5. The brake lever is connected to the link (16) (17) and the brake plate (18), and when the grip of the brake lever is released, the brake plate connected to the gas spring (5) pressurizes the warp or the belt conveyor and stairs. The structure is such that it stops even in the middle.
6. When climbing stairs, a pair of lever rods (19) and pushers (21) are connected to a rotatable pin (22) with a pin (23) to a support (13). When the caregiver moves the brake lever (14) up and down, the pin plunger of the brake lever holding plate (20) goes in and out of the hole of the brake lever, and the brake can be turned on / off.
