Abstract

PROBLEM TO BE SOLVED: To provide an elevating device simple in structure, manufactured safely and firmly at a low cost and smart in appearance with mechanical parts concealed inside. SOLUTION: An elevating device comprises a belt conveyor 1 disposed parallel with stairs A in a state of inclining at the same angle as an angle of inclination of the stairs A; a chair 2 fitted to the belt conveyor 1; a motor for driving the belt conveyor 1 in a reciprocating range of the chair 2 from the lower part to the upper part of the stairs A; and a switch S for operating the motor.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lifting device attached to a side of a stair and used by a physically handicapped person or an elderly person with weak legs.

[0002]

2. Description of the Related Art Hitherto, various types of elevating devices that are attached to and used in parallel with stairs for physically handicapped persons and elderly people with weak legs are already known.

[0003]

However, in the conventional type, the liner to which the chair is attached moves along a channel-shaped guide rail or a monorail, so that the rail portion is exposed to the outside. In addition to being unsightly, there are drawbacks in that the structure is complicated, installation work is troublesome, and the total cost is very high.

Accordingly, an object of the present invention is to provide a lifting device which has a smart appearance with a mechanical part hidden inside, and which can be manufactured inexpensively, safely and firmly with a simple structure.

[0005]

In order to achieve the above object, the present invention takes the following technical measures. That is, in the elevating device according to the present invention, the belt conveyor 1 arranged in parallel with the stairs A while being inclined at the same angle as the inclination angle of the stairs A, and the chair attached to the belt conveyor 1 2, a motor M for driving the belt conveyor 1 within a range where the chair 2 reciprocates from the lower part of the stairs to the upper part, and a switch S for operating the motor M.

With such a structure, the mechanical part of the lifting device can be hidden by the belt 3 of the belt conveyor 1 so that the appearance can be organized and the chair 2 can be directly mounted on the belt 3. Since it can be installed, it can be installed stably and reliably.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The details of the present invention will be described below based on embodiments. In the figure, reference symbol A denotes a stair in a house or the like, and the belt conveyor 1
Are arranged in a state of being inclined at the same angle as the angle of inclination of.

The belt conveyor 1 comprises an upper wheel 4, a lower drive wheel 5, and an endless belt 3 stretched between the wheels, on which the chair 2 faces the stairs. It is mounted so that it can be easily seated from. The driving wheel 5 of the belt 3 is connected to a motor M, and the belt is formed so as to reciprocate up and down within a range in which the chair 2 reciprocates from the lower part of the stairs to the landing 6 on the upper part of the stairs. The chair 2 is provided with a switch S for operating the motor M.

In the embodiment shown in FIG. 1, the upper part of the belt 3 and the part other than the chair 2 attached thereto are formed by being covered with a cover 7, and the lower drive wheel 5 and the motor M are mounted on the floor. It is located under surface 8. Thereby, the mechanical part can be simply and smartly finished as a whole without being exposed to the outside.

When the chair 2 moves from below to the landing 2 on the stairs and from above to the lower part of the stairs in FIG. 1, the belt conveyor 1 detects the position of the chair 2 by detecting a limit switch or the like. It is preferable that the motor M is formed so as to be automatically stopped by means. Thus, the chair can be raised and lowered to the home position simply by turning on the switch S while sitting on the chair from the lower side of the stairs or from the upper end side.

The belt 3 does not necessarily have to be endless, and each end of the endless belt is connected to the upper and lower rings 4.5.
It is also possible to form so as to wind each. Further, if the chair 2 can be rotated by a predetermined angle, it is convenient when sitting down.

Although the embodiment of the present invention has been described above, the present invention is not necessarily limited to the structure of the embodiment, but includes the constituent elements and achieves the object of the present invention. The present invention can be appropriately modified within the range in which the effects can be obtained.

[0013]

Since the present invention is constructed as described above, the mechanical part of the elevating device is hidden by the belt of the belt conveyor so that the appearance can be simply and simply organized, and the chair can be placed on the belt. Since it can be directly attached, there is a remarkable effect that it can be installed stably and reliably, and the structure is simple and it can be manufactured at low cost.
