Description

  The present invention relates to a joint device used as a gate door or the like that covers an opening between wall surfaces of a portion that connects buildings, or that has a rail on the ground serving as an opening.

  Conventionally, joint devices that use rails to move the doors and joint plates are open because the rails of the parts where the doors and joint plates are not always located are open. There were drawbacks in that the joint plate malfunctioned, the aesthetic appearance was impaired, and it became unsanitary.

Japanese Patent No. 4729510

  In view of the above-described conventional drawbacks, the present invention efficiently covers the gate that covers the opening that moves while being guided by the rail, and the upper part of the rail portion where the joint plate is not always positioned, so that dust and the like can be efficiently collected. An object of the present invention is to provide a joint device that can prevent well and prevent malfunction, and can efficiently prevent aesthetic improvement and poor hygiene.

The above and other objects and novel features of the present invention will become more fully apparent when the following description is read in conjunction with the accompanying drawings.
However, the drawings are for explanation only and do not limit the technical scope of the present invention.

  In order to achieve the above object, the present invention provides a hat-shaped steel attached so that the upper part or the lower part is opened on the ground, the floor surface on which the opening is formed, or the ceiling surface. In a joint device composed of a channel-shaped rail and a joint plate that moves while being guided by the rail, the joint plate attached to the upper position of the rail portion where the joint plate is not always located is moved. An opening / closing door having a pair of opening / closing door bodies provided with an urging mechanism for urging in a normally closing direction that is pressed and opened in the direction of both sides when coming, and the joint plate corresponding to the opening / closing door And a chevron-shaped protrusion that enters and opens between the pair of opening / closing door main bodies to constitute a joint device.

As is clear from the above description, the present invention has the following effects.
(1) According to the first aspect, the pair of doors including a biasing mechanism that constantly biases the rail of the portion where the joint plate is not positioned in the closing direction can be closed.
Therefore, it is possible to reliably prevent dust from entering the rails closed by the pair of opening / closing doors, and to improve aesthetics and prevent unsanitary conditions.
(2) According to the above (1), when the joint plate moves, the pair of opening and closing doors are moved by the chevron-shaped projections provided at the end of the joint plate, so that the joint plate can move relatively smoothly. Since the joint plate acts to press the joint plate with the pair of opening and closing doors, it is possible to efficiently prevent the joint plate from swinging in the direction perpendicular to the moving direction of the joint plate.
(3) According to the above (1), it is only necessary to provide a pair of opening / closing doors provided with a biasing mechanism on a hat-shaped steel or channel-shaped rail, and a mountain-shaped projection on the joint plate, so that it is installed relatively easily And can be easily installed on existing rails.
(4) According to the second aspect, the same effects as in the above (1) to (3) can be obtained, and the upper portion of the rail can be reliably closed at all times.
