Description

  The present invention relates to a gap sealing tool for sealing a gap generated at a connecting portion between doors in a folding door, and a method for attaching to a folding door.

  Conventionally, folding doors used for storage furniture such as clothes chiffon, storage fittings such as closets or partition doors, as shown in FIG. 9, the side edge portions of a plurality of doors 50 and 50 are hinged to each other, The upper rail 52 and the lower rail 53 are attached to the upper and lower frame portions of the mounting frame, respectively, and are fitted and fixed to the upper and lower rails 52 and 53, for example, on the upper and lower portions of the folding door. Bearing brackets 54 and 55 that are fixed at predetermined positions of the rail by a mechanism are provided, and pivots on the upper and lower ends of the folding door are rotatably supported by these bearing fittings 54 and 55, respectively. Are attached to runners 56 and 57 that are movable along the upper and lower rails 52 and 53 in accordance with the opening and closing.

  In the folding door, a gap is generated in the door connecting portion with opening and closing of the folding door. If the door is closed with a finger inadvertently sandwiched in the gap, an accident occurs that the finger is crushed with a very large force. Due to the danger, several devices for closing the gap between the door connecting portions have been proposed in recent years.

  For example, in Patent Document 1 below, a cover that covers a folded portion of a folding door having first and second doors that are foldably connected to each other, and a connection portion of the cover and the door are connected to each other. There has been proposed a folding door gap cover device provided with a joint mechanism that follows rotation of a connecting end portion that occurs during bending.

  In the following Patent Document 2, a door fingering prevention cover composed of four plate-shaped covers having bent portions is proposed.

  In the following Patent Document 3, a door body that is formed by connecting a plurality of panels so as to be bent, and a finger-filling space between adjacent panels that open and close in accordance with the folding of the door body is flexible. When covering with the finger padding prevention cover, the finger padding prevention cover is attached across adjacent panels, and substantially corresponds to the opening width of the finger padding space at the intermediate part of the flexible part that connects the attachment parts. When the finger padding space is closed on the inner surface of both ends of the hard part, the hard part is extruded and guided outward based on contact with the panel body corner part. A finger padding prevention cover for a door body having an inclined surface has been proposed.

Furthermore, in the following Patent Document 4, as shown in FIG. 10, a folding door gap cover device that covers the gap between the first and second doors of a folding door in which the first and second doors are foldably connected. The cover 60 that covers the folded portion of the folding door from the outside, both end portions of the cover 60 and the first and second doors are connected to each other, and are rotated with respect to the cover 60 and the door. The fold door clearance cover is provided with movably connecting portions 61 and 61, and when the folding door is closed, the connecting portions 61 and 61 support the cover 60 in a state of approaching or abutting the door. A device has been proposed.
