Description

[Detailed description of the device] [Industrial applications]

The present invention relates to a gate, and more particularly to a gate that can be laterally slid and opened / closed in a state where a plurality of doors are connected without being suspended.

[Prior art]

Conventionally, as a gate that opens and closes by sliding multiple doors sideways,
It is known that the rail is suspended above a rail that is laid horizontally.

[Problems to be solved by the device]

The hanging type gate has a feature that it can be easily slid sideways even if it is a large door body. For example, it is used as a gate at the entrance of a construction site. However, there is a problem that the height of entrance and exit of trucks is limited, and when trying to match the height of the load of the truck, the height of the rail is increased and the gate becomes larger than necessary. there were. In view of these problems, the present invention was developed for the purpose of providing a gate door capable of laterally slidingly opening and closing a plurality of door bodies instead of a hanging type.

[Means for solving problems]

In order to solve the above problems and achieve the object, the present invention provides (a). Forming a dovetail-shaped guide groove along the wide surface of the door body at the upper end surface and / or the lower end surface of the adjacent door body, (b). A spacer for setting a predetermined interval between adjacent door bodies is provided in the center to provide guide rails that straddle both door bodies, and guide walls provided on both sides of the guide rails are provided to mutually adjacent door bodies. It is slidably fitted in the groove portion on the inner side of the formed guide groove, (c). A door stopper is provided which abuts the door and an adjacent door so that they do not separate from each other at the deployed position, and when the folding is performed, the adjacent doors abut at a position where the adjacent doors overlap with each other. When the doors were deployed, the guide rails were pulled out to the central position between the adjacent doors, and when folding, a guide rail stopper that interlocks the guide rails with the doors was provided.

[Action]

The plurality of doors are connected by a door stopper and a guide rail so as not to be separated in the wide surface direction. In addition, the guide rail stopper is displaced in conjunction with the expansion or folding operation of the door body to a central position between the adjacent door bodies where the guide rail is expanded and a position where the guide rail overlaps with the folded door body. As a result, each door can be laterally slid in the direction along the wide surface by being guided by the guide rail, so that when installing this at the gate, the lower guide rail can be fixed by the casters without the suspension rail installed. The door between the upper and lower guide rails can be opened and closed by sliding in a sliding manner like a sliding door.
