  JP 2001-65235 A   JP 2004-27667 A

  Conventionally, when constructing a sliding door, the groove or rail provided in the ceiling or the headquarters, etc. is used as a guide, the upper end of the sliding door is inserted, and the lower end of the sliding door is installed on a guide such as a rail installed on the floor surface etc. Because the space between the ceiling and the floor surface is wide and narrow due to the undulation of the ceiling surface or floor surface, etc., the hooking dimension of the upper edge of the sliding door inserted into the groove or rail provided in the ceiling or duck, etc. However, it was difficult to keep the upper edge of the sliding door constant.

  In addition, in the type of sliding doors that use a rail attached to the ceiling or the headquarters as a guide and a door is placed on the top surface of the sliding door and hangs from the ceiling, in recent years, rails have been installed on the floor surface less frequently. The floor is fixed at a fixed point so as to be inscribed in the groove, etc., and the sliding door is prevented from sideways swinging. , The floor may come off the steady rest and the sliding door may float in the air.

  For this reason, the means disclosed in Patent Document 1 for urging by a spring so that the wheel fitted in the casing protrudes upward is described. In Patent Document 2, the upper end of the sliding door body is a guide groove. An example in which a separation preventing piece is provided so as not to be detached from is described.

  In recent buildings, barrier-free has come to be advocated, and the groove of the rail installed on the floor tends to be reduced or eliminated, so if impact is applied from the side of the sliding door body In the case of a sliding door with a rail installed on the floor, the sliding door may fall over, for example, when the door wheel is lifted off the rail and then removed from the rail.

  In addition, the space between the ceiling and the floor surface is wide and narrow due to the undulation of the ceiling surface or floor surface, etc., so the catching dimension of the upper edge of the sliding door inserted into the groove or rail provided in the ceiling etc. When the impact is applied from the side of the sliding door main body at a location where the hooking dimension of the upper edge of the sliding door is not constant, the sliding door may come off from the groove or rail, and the sliding door may fall down.

  In order to solve the above problems, the present invention is a sliding prevention device that prevents the sliding door from coming off from the sliding door rail in a sliding door that runs using a rail or the like attached to the ceiling or floor of a building as a guide, Formed in a box shape, the body part with wheels arranged on the side so that it can run in the auxiliary rail arranged on the ceiling, the insertion part is provided on the upper side of the body part, and the lower side is formed in a substantially C shape The drive body provided with the lower opening and the insertion port provided in the upper edge of the sliding door, which is inserted through the insertion port on the upper surface of the drive body and is movably locked in the holding portion of the insertion port. Inserted from the locking hole on the upper surface of the fixed body that is inserted and fixed in the sliding door, and follows the swell of the ceiling surface, floor surface, etc. by the locking piece such as a rivet from the holding hole provided on the side wall of the fixed body And can be moved up and down through the locking hole A suspension wheel that is held by a rail that is fixed to the ceiling or a door wheel that moves on a rail fitted to the floor surface is removed, and even if the sliding door is shaken, it has a substantially C shape. Due to the formed lower opening, the locking plate follows the side swing of the sliding door so that the sliding door itself does not come off.

  In addition, the locking plate is formed integrally with the shaft center, is formed in a box shape, and the lower side surface of the driving body with the wheels arranged on the side surface so that it can run in the auxiliary rail arranged on the ceiling has a substantially C shape. It was formed and inserted and fitted into the substantially C-shaped part, so that the locking plate followed the vibration of the sliding door to prevent the sliding door itself from coming off.

  Further, the driving body wheels are eliminated, and the driving body slides in the auxiliary rail, but the moving body moves so that the fixed body inserted and fixed in the insertion port provided on the upper surface of the sliding door is from above the sliding door. It is fixed to the sliding door with screws.

  At the lower part of the driving body, the locking part protrudes in a substantially circular shape at the tip and is integrally formed with the driving body, and the fixed body inserted and fixed in the substantially circular insertion port provided in the upper surface part of the sliding door is substantially cylindrical. It is formed in a shape and is held by a rail or the like that is inserted into the fixed body wall and fixed to the ceiling so that the locking part can follow the undulations of the ceiling surface or floor surface, and can move up and down the fixed body wall. It is formed so as to coincide with the locking portion 4 formed in a substantially circular shape at the tip even if the suspension wheel or the door wheel moving on the rail fitted on the floor surface is detached and the sliding door swings. Due to the inner wall of the fixed body 3, the locking portion 4 vibrates in such a manner that it can follow the lateral swing of the sliding door.

  In the implementation of the present invention, the space between the ceiling and the floor surface is wide and narrow due to the undulation of the ceiling surface or the floor surface, so that it is inserted into a guide such as a groove or rail provided on the ceiling, etc. If the hooking dimension of the upper edge is not constant, and an impact is applied from the side of the sliding door body at a shallow part of the sliding door upper edge, the sliding door will come off the guides such as grooves and rails, and the sliding door will fall. In order to prevent this, the locking plate follows the swell of the ceiling surface and the floor surface by the retaining holes provided on the side wall of the fixed body and the locking holes arranged at the lower part of the locking plate by the locking pieces such as rivets. Therefore, the hooking dimension of the upper edge of the sliding door inserted into a guide such as a groove or rail provided on the ceiling or the like is always set constant, and the driving body is Since it is fitted to the auxiliary rail, it will fall over even if the sliding door comes off the rail. Is there is no safety.

  In addition, the locking plate is formed integrally with the shaft center, the wheel of the driving body is abolished, the driving body slides in the auxiliary rail, but it moves very much, and the insertion port provided on the upper surface of the sliding door If the fixed body to be inserted and fixed is configured to be fixed to the sliding door with a screw from above the sliding door, the number of parts can be reduced, the manufacturing cost can be suppressed, and it can be provided at low cost.
