Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator for a wheelchair user who carries a wheelchair user, and more particularly to an elevator for a wheelchair user who can cross a pedestrian bridge, a crotch bridge or the like without the help of a healthy person. The present invention relates to an elevator for wheelchair users.

[0002]

2. Description of the Related Art When a wheelchair user uses an elevator, it is dangerous if the user always moves in the forward direction to get on and off the elevator cage. In a general elevator, the entry position and the exit position are the same, so it is necessary to change the direction in the elevator cage from getting on the elevator cage to getting down.
This change is not possible for a single wheelchair user without a caregiver. For this reason, an elevator for a wheelchair user having an entrance at the front and back of an elevator cage is known. In this elevator for wheelchair users, the wheelchair user can always move forward and get on and off the elevator cage, but the entry position and the exit position on each floor are limited to opposite directions, and the entry position and the exit position on each floor are set in the same direction or at a right angle. The direction, etc., could not be set arbitrarily.

As an elevator that solves this problem, as shown in FIG. 10, an elevator for a wheelchair user provided with a turntable 3 on a floor 2 of an elevator car 1 is also known. When the wheelchair user gets into the basket 1 and operates the operation switch, the turntable rotates by 180 °, so that the wheelchair user can get off at the same position as where he / she got on.

[0004]

However, the floor surface 2
In the elevator for a wheelchair user provided with the turntable 3, the wheelchair is turned inside the elevator cage 1, so that a space having a diameter R is required, and the floor area of the elevator cage 1 becomes large. Generally, elevator cage 1
Is calculated with the load per unit area of the floor constant, so the larger the floor area, the larger the number of mounted persons, the larger the elevating power and the larger the structure, and as a result, the elevator installation area and cost Has a great effect on

[0005] When the wheelchair is turned in the elevator car 1, if there are many people around the wheelchair, the turning may be hindered. Further, since the wheelchair user needs to operate the operation switch, if the user forgets the operation, there is a possibility that getting on and off the vehicle may be hindered.

Therefore, the present invention can reduce the floor area of an elevator car, and furthermore, set the boarding position and the descending position of each floor in any direction, for example, the same direction, the opposite direction or the right angle direction. As a result, an object of the present invention is to provide an elevator for a wheelchair user that can be easily installed in an existing building such as a pedestrian bridge.

[0007]

Hereinafter, the present invention will be described. The inventor reduced the floor area of the elevator cage, and furthermore, in order to be able to set the entry position and the descending position of each floor in any direction, without providing a turntable in the elevator cage, the entire elevator cage was Turned. In order to further reduce the floor area, focusing on the fact that the passengers of the elevator for wheelchair users are at most about wheelchair users and attendants, and that the projected shape of the wheelchair is vertically long, The surface was square at the center and fan-shaped at both ends. That is, the invention of claim 1 includes an elevator cage provided with an entrance at a diagonal position on a side surface, a lifting device for lifting and lowering the elevator cage, and a turning device for turning the elevator cage. By the elevator for wheelchair users, the floor is made square at the center and fan-shaped at both ends.
The above-mentioned problem has been solved.

According to the present invention, since the entire elevator car is turned, no space is required for the elevator car to change the direction as in the case where a turntable is provided, and the floor area of the elevator car can be reduced. In addition, the entry position and the exit position on each floor can be set in any direction. Also, make the floor of the elevator cage a square at the center,
Since both ends are fan-shaped, the shape of the floor surface can be adjusted to the projected shape of the wheelchair user, and the floor area can be further reduced. If the floor of the elevator cage is square,
Since the corner of the basket swings, the turning radius increases. On the other hand, when the floor surface of the elevator cage is circular, the projected shape of the wheelchair is vertically long. Therefore, merely reducing the diameter of the circular floor shape limits the reduction of the floor area, resulting in an unnecessary area on the floor surface.

As described above, as a result of reducing the floor area of the elevator cage, it is possible to reduce the load capacity of the elevator in proportion to the floor area. Therefore, the size of both the lifting device and the turning device can be reduced, and the installation area of the elevator can naturally be reduced, so that an elevator for wheelchair users who can easily be installed in an existing building can be obtained. In addition, since the getting on / off direction of each floor can be set arbitrarily according to the existing work, the same elevator for wheelchair users can be applied even if the getting on / off position changes depending on the work, and an economical elevator for wheelchair users can be used. can get.

The present invention also provides an elevator door having an opening and closing door for opening and closing the entrance, wherein the cross section of the opening and closing door in a horizontal plane is formed in an arc shape in accordance with the fan-shaped floor surface. Are opened and closed in the circumferential direction of the sector.

According to the present invention, since the opening and closing door opens and closes in the circumferential direction, no extra space is required for opening and closing the opening and closing door, and the elevator cage can be made smaller.

Further, according to the present invention, the opening / closing door is formed in a substantially cylindrical shape and has an opening corresponding to the entrance at only one location in the circumferential direction, and one opening / closing door is provided for the elevator cage. A pair of the entrances provided on the side face are opened and closed.

According to the present invention, the safety of the elevator is further improved because the pair of entrances does not open simultaneously. In addition, since the pair of doors is opened and closed by one door, the structure of the elevator cage can be simplified.

Further, the present invention is characterized in that the elevator cage is suspended by the lifting device, and the turning device is interposed between the elevator cage and the lifting device.

According to the present invention, since the turning device and the elevating device are provided above the elevator cage, the space below the elevator cage can be reduced. For this reason, the pit at the time of installing an elevator can be made shallow, and a more economical elevator with less installation cost can be obtained.
