Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle elevator door.

[0002]

2. Description of the Related Art An elevator for a vehicle is an elevator dedicated to a vehicle that elevates and lowers a vehicle that has been loaded into a car. However, when a large-sized vehicle that can be loaded into the car, the front bumper collides with the car. Could cause a damage accident.

Therefore, as disclosed in Japanese Patent Laid-Open No. 6-72677, an opening is provided in the center of the car door in the width direction, and a panel disposed in the opening is used as an elastic body through a plurality of springs. It has been proposed to employ a structure in which a car door is supported so as to include a buffer portion intended to prevent a damage accident by moving the panel even if the bumper of the vehicle collides with the panel.

[0004]

However, in the above-mentioned prior art, the buffer portion is attached to the car door by a spring, and the period in which the elastic force is retained is short and the elastic force disappears every time. Since it has to be replaced, there is a problem that the replacement work and the tension adjustment work are complicated.

The present invention has been made in view of the above problems, and an object of the present invention is to provide an elevator door for an automobile that does not require the replacement work and the adjustment work.

[0006]

In order to achieve the above object, the present invention provides an elevator for an automobile having a cushioning portion for absorbing an impact force generated by a collision of the automobile with a car door in a traveling direction of the automobile. In the above door, the cushioning portion is attached to the car door via a rotatable hinge.

[0007]

Since the present invention is configured as described above, when the front portion of the automobile comes into contact with the cushioning portion when the automobile gets into the car, the cushioning portion rotates through the hinge with respect to the car door. It moves and absorbs shock. As described above, since the cage door and the cushioning portion are attached by the hinge, the replacement work and the adjustment work which are required in the related art are not required.

[0008]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of the entire car of an automobile elevator according to an embodiment of the present invention, FIG. 2 is a block diagram of the car door of the automobile elevator shown in FIG. 1, and FIG. 3 is a sectional view.

In these drawings, reference numeral 1 is a car for an automobile elevator, 2 is a car which is in the car 1 and is to be lifted, 3 is a car door facing the front side of the car 2, and 4 is a car door. A cushioning portion formed of a panel attached to the central portion in the width direction of 3 is a plurality of elastic members that connect one end portion of the cushioning portion 4 to the car door 3, and 6 is the other end portion of the cushioning portion 4. A rotatable hinge connected to the car door 3, 7 is a landing, 8 is a car door facing the rear side of the automobile 2, 9 is a landing door, and the car doors 3 and 8 are connected to the chain 10. It can be hung up and stored above the car 1 or lowered to shield the front and back of the car 1. A car stop 1b is fixedly installed on the floor 1a of the car 1 to define a permissible range of a boarding position of the automobile 2 in the car 1.

Further, in the center portion in the width direction of the car door 3,
An opening 3a is provided at a position facing the bumper 2a of the automobile 2, and the opening 3a is closed on the landing side (the side opposite to the automobile 2 side) of the opening 3a larger than the opening 3a. The buffer section 4 is arranged. Then, one ends of the elastic body 5 and the hinge 6 are attached to the attachment portions 3b and 3c around the opening 3a, and the attachment portion 4 of the buffer portion 4 is attached.
The car door 3 and the buffer portion 4 are connected to each other by being attached to a. Normally, the buffer portion 4 is connected by the pulling force of each elastic body 5.
It is pressed against the peripheral portion of the opening 3a of the car door 3.

Now, assuming that the automobile 2 is smaller than the one shown in the drawing, the driver of the automobile 2 who gets into the car 1 from the landing 7 has the front wheels 2b at the latest at the car door 3.
Since the automobile 2 is stopped when it comes into contact with the side vehicle stop 1b, the bumper 2a does not collide with the car door 3, but when the automobile 2 is relatively large as shown in FIGS. The bumper 2a collides with the panel 4 before the front wheel 2b contacts the car stop 1b on the car door 3 side. However, in this embodiment, when such a collision occurs,
Since the elastic body 5 extends around the rotatable hinge 6 and the panel 4 quickly rotates outward, the car door 3 and the panel 4 are prevented from being damaged or damaged and the automobile 2 The driver can be made aware of the contact of the bumper 2a.

Further, in this embodiment, as described above, the panel 4 is normally pressed against the peripheral portion of the opening 3a of the car door 3 by the pulling force of the elastic body 5. Further, since the buffer portion 4 is fixed to one end of the car door 3 by the rotatable hinge 6, unnecessary vibration does not occur.
The buffer 4 does not collide with the car door 3 or the hoistway projections during the opening and closing of the door or during elevator travel, resulting in noise or a serious accident. Since the car door 3 is provided at the opening 3a, the driver can see the inside of the hoistway through the opening 3a and cause anxiety and fear. However, since the buffer portion 4 closes the opening 3a in this embodiment,
The inside of the hoistway cannot be visually observed from the inside of the car 1, so that the driver is given a sense of security.

In this embodiment, since one end of the attachment of the car door 3 and the buffer portion 4 is connected by the rotatable hinge 6, replacement work and adjustment work at this hinge 6 portion are required. do not do. Further, the car door 3 and the cushioning portion 4 are attached to each other by connecting the hinge 6 whose one end is rotatable and the elastic end 5 to the other end, so that the pulling force of the elastic body 5 is reduced. Therefore, the period in which the elastic force of the elastic body 5 is maintained and the replacement cycle can be extended.

In each of the above-mentioned embodiments, the car door 3 has been described, but the car door 8 and the landing door 9 have the same structure to prevent damage accidents and improve safety. Needless to say, it can be achieved.

[0016]

According to the present invention, since one end of the attachment of the car door and the buffer portion 4 is connected by the rotatable hinge, the replacement work and the adjustment work at the hinge portion are not required. .

Further, since the tensile force applied to the elastic body is reduced, the period in which the elastic force of the elastic body 5 is held and the replacement cycle can be extended.
