The doors 101, 1 are attached to the front ends of the doors 101, 102.
The door bumper 10 is provided in order to buffer the shock when the 02 is closed and brought into contact with it, and to reduce the abnormal noise generated at this time.
3, 104 are provided. That is, the door 101,
Holding members 105 and 106 each having a substantially U-shaped cross section are fixed to the tip end side of 102 by a plurality of screws 107 and 108, and the bumpers 103 and 104 are held by the holding members 105 and 106.

所の方が多いものである。In the conventional elevator door bumpers 103 and 104 as described above,
The recesses 103b. 104b is screw 1
This is for letting the heads of the screws 07 and 108 escape, but as shown in FIG. 6, there are more places where the heads of the screws 107 and 108 are not located.

という問題点があった。By the way, if the hardness of the bumpers 103 and 104 is increased, it is difficult to absorb the impact and the noise is increased. Therefore, if the hardness of the bumpers 103 and 104 is lowered, when the doors 101 and 102 are closed, the other bumper 103 is pushed by the protruding portion 104a of the one bumper 104 and elastically deforms toward the recess 103b. become. Therefore, the doors 101 and 102 are mounted on the bumper 10
The shock is not buffered by 3, 104, but directly abuts. As a result, there is a problem in that the durability of the doors 101 and 102 is reduced and the abnormal noise generated at this time is increased.
【０００６】本発明は、一対のドアを閉める際に、直に
当接しないようにしたエレベーターのドア用バンパーを
提供することを目的とする。An object of the present invention is to provide a bumper for an elevator door, which does not come into direct contact with each other when the pair of doors are closed.

ドアが直に当接するのを防止することができる。Since the concave portion of the other door bumper is not located on the other door bumper with which the protruding portion of the one door bumper abuts, the other door bumper is elastic toward this concave portion. There is no deformation. Therefore, the pair of door bumpers can buffer the impact when the pair of doors come into contact with each other, and thus prevent the pair of doors from directly coming into contact with each other.

8c is formed in the center line direction, and a projecting portion 7d, a receiving portion 7e, a projecting portion 8d, and a receiving portion 8e are formed on the tip end side, respectively. The protruding portion 7d and the receiving portion 7e and the protruding portion 8d and the receiving portion 8e are provided on the left and right sides of the center line of the front end side of the door bumpers 7 and 8, respectively. Therefore, the protruding portions 7d and 8d and the receiving portions 7e and 8e are at positions displaced from the centers of the concave portions 7c and 8c. The protruding portion 7d and the receiving portion 7e of the door bumper 7 face the receiving portion 8e and the protruding portion 8d of the door bumper 8, respectively.

るのを防止することができる。When the doors 1 and 2 are closed, the front ends of the doors come into contact with each other, but the door bumpers 7 and 8 cushion the impact at the time of this contact. In order to effectively perform the cushioning at this time, the door bumpers 7 and 8 having low hardness are used. Then, the recesses 7 are formed in the door bumpers 7 and 8.
Since c and 8c are formed, these are the recesses 7
C and 8c are greatly elastically deformed, and there is a possibility that the doors 1 and 2 may directly contact each other. However, as shown in FIG. 3, since the recess 8c is not located in the door bumper 8 with which the protrusion 7d abuts, the bumper 8 does not elastically deform toward the recess 8c. Similarly, the door bumper 7 does not elastically deform toward the recess 7c. Therefore, the door bumpers 7 and 8 can sufficiently absorb the impact when the doors 1 and 2 come into contact with each other, and thus the doors 1 and 2 can be prevented from directly coming into contact with each other.

Since the protruding portion and the receiving portion are formed at positions deviated from the center of the concave portion, and one of the protruding portion and the receiving portion abuts the other receiving portion and the protruding portion, respectively,
When the pair of doors are closed, they are prevented from directly contacting each other. As a result, the durability of the door is improved, and abnormal noise generated at this time can be reduced.
