Description

  The present invention relates to a sliding door brake device that can be easily constructed and has excellent versatility.

  Conventionally, when closing the sliding door without force to the door until it is completely closed, the door end face collides with the sliding door frame and generates an impact sound. There was a problem of returning with the momentum of the collision.

  In order to solve this, various brake devices for sliding doors have been considered. For example, in Patent Document 1, either the upper surface of the sliding door on the door contact side or the lower surface of the sliding door frame upper frame on the door contact side is considered. A pair of brake plates are arranged opposite to each other along the traveling direction of the sliding door, and on the other side, a brake piece is disposed between the pair of brake plates and is brought into contact with the brake plate to stop the sliding door, As for the brake piece, a brake device for a sliding door provided with a dimension adjusting means for adjusting the dimension in the width direction of the brake piece is disclosed.

According to this brake device, even when the sliding door is driven vigorously toward the door stop side, the sliding door can be stopped quietly and reliably in the door stop, preventing the generation of impact sound and the return of the sliding door. It was possible to provide an easy-to-use sliding door brake device and to solve the above problems.

Eventually, the adsorbing part and the adsorbed part are adsorbed to prevent the sliding door from returning.

  According to a second aspect of the present invention, in the sliding door brake device according to the first aspect of the present invention, a buffer portion is provided on the vertical contact surface of the sliding door body, and an adsorption portion is provided on the vertical frame contact surface of the sliding door frame. This makes it easier for the sliding door frame side to pass, and the buffering portion with a damper that has a stress absorption capacity that matches the weight of the sliding door body is used for the sliding door in advance, while the suction portion of the sliding door frame remains unchanged. By doing so, it is possible to reduce the number of parts by using a common suction part.

  According to a third aspect of the present invention, the buffer body is screwed onto the buffer base material embedded in the vertical contact surface of the sliding door main body or the vertical frame contact surface of the sliding door frame according to the first or second aspect. Therefore, when the frictional force of the sliding door or the absorption capacity of the damper changes due to secular change, the buffer body can be easily removed from the buffer base material embedded in the sliding door body, and the damper can be adjusted. Maintenance such as making the brake force appropriate can be easily performed.
