Description

  The present invention relates to a sliding door automatic door device which is installed at a doorway of a building and the like and automatically opens and closes a door by detecting a passerby or the like.

  2. Description of the Related Art Conventionally, as described in Patent Document 1, a sliding door automatic door device is known that is provided at an entrance of a building and the like and detects a passerby by an optical sensor or the like to automatically open and close the door.

  The door body of the sliding door automatic door device is generally composed of transparent glass and a steel frame except for wooden ones. Door bodies using such glass are widely used because they can ensure the visibility required for traffic and are excellent in design.

  In such a sliding door automatic door device, the door main body is slidably supported by the support rail at the upper side portion, and is supported in a state of being suspended by the support rail. The lower side portion of the door body is inserted into a guide groove parallel to the support rail formed on the floor surface, and is slidable. In addition, the lower side part of the door main body inserted in the guide groove is formed of a resin material.

  That is, the door body is slidable in the direction along the support rail and the guide groove in a state in which the guide groove prevents the swing in the direction orthogonal to the main surface of the door body.

  Conventionally, the width of the guide groove formed on the floor surface was about 17 mm, but it is desirable that the width is as narrow as possible from the viewpoint of barrier-free. That is, if the width of the guide groove is wide, a pedestrian walking on the floor surface on which the guide groove is formed may scoop by the guide groove, or the wheelchair wheel traveling on the floor surface may fit into the guide groove. .

  Therefore, in recent years, a sliding door automatic door device having a guide groove width of 6 mm or less has been proposed. In this case, a thin plate-like steady stop called a Russell plate is attached to the lower side portion of the door body, and the Russell plate is inserted into the guide groove.

JP 2009-256882 A

  As described above, in the sliding door automatic door device, it is desirable that the width of the guide groove into which the Russell plate attached to the lower side portion of the door body is inserted is as narrow as possible. However, if a guide groove having a width of 6 mm or less is formed on the floor surface, if dust or the like enters the guide groove, it is difficult to remove it and the maintainability is poor.

  Therefore, conventionally, it has been proposed that the width of the guide groove is about 17 mm, and the inside of the guide groove is filled with a core material having a width of 10 mm or more to be used as a narrow guide groove. That is, the Russell plate is slid between one side portion of the guide groove and the side surface portion of the core member (a gap having a width of 6 mm or less). The upper surface portion of the core material is flush with the floor surface. If it does in this way, if a core material will be removed from the inside of a guide groove, it will be easy to remove the dust etc. in a guide groove.

  However, the core material in the conventional sliding door automatic door device must be installed in the guide groove before the door body is attached to the rail at the time of construction. This is because the guide groove in the sliding door automatic door device is such that the area where the door body exists is hidden by the door body, and the opening width of the sliding door automatic door device is narrower than the lateral width of the door body. . Therefore, in order to attach and detach the core material over the range in which the door body slides, the door body must be removed from the rail.

  Further, the Russell plate in the conventional sliding door automatic door device cannot be attached to the door body unless the door body is removed from the rail. Therefore, the Russell plate must be attached to the door body before the door body is attached to the rail during construction.

  Then, when the door body is attached to the rail, the door body is suspended from the rail while the Russell plate attached to the door body is inserted between one side portion of the guide groove and the side surface portion of the core member. Since the door body weight may exceed 100 kg, it is extremely difficult to stand the door body while inserting a thin Russell plate into the narrow gap between one side of the guide groove and the side of the core. It is a difficult task and the workability is poor.

  Therefore, the present invention is proposed in view of the above circumstances, and in a sliding door automatic door device provided with a core material for filling a guide groove and using it as a narrow guide groove, An object of the present invention is to provide a sliding door automatic door device in which a Russell plate attached to a lower side portion can be attached to and detached from the door body without removing the door body from the rail.
