Description

The present invention relates to an opening device in which a shoji can be opened and closed in a frame provided in a building opening, and more particularly to an opening device that prevents a shoji from being opened by being restrained by a frame even when a fire occurs.

In an opening device in which a shoji is opened and closed in a frame provided in a building opening, the shoji is constrained and locked with respect to the frame. However, depending on the type of the opening device, when exposed to a high temperature in the event of a fire, the shoji restraint may be released and the shoji may open. For example, in an opening device that restrains a shoji with a wire via a pulley, the resin pulley may be melted by being exposed to a high temperature and lose the binding force of the wire.

In order to maintain the restraint state of the shoji even in the event of a fire, there is known one in which an opening device is provided with a lock mechanism that operates as the temperature rises. As a lock mechanism, for example, as shown in Patent Document 1, a fuse member that melts at a predetermined temperature, a spring member that operates when the fuse member melts, and a plate member that springs up by the spring member are attached to a shoji. When a fire occurs and the opening device is exposed to a high temperature, the jumped plate member is locked to the frame body, thereby maintaining the locked state. Patent Document 2 discloses one using a shape memory alloy instead of a fuse member and a spring member.

However, the conventional lock mechanism has a problem that the mounting position is limited. Since the temperature in the opening device at the time of a fire varies greatly depending on the position depending on the fire situation, the temperature at the mounting position of the lock mechanism does not exceed the predetermined value until the shoji restraint is released Cases are also conceivable. In addition, it is necessary to prepare dedicated parts such as a fuse member, a spring member, and a shape memory alloy part, which causes a cost increase. Furthermore, since the spring member has a characteristic that the elastic force becomes weaker as the temperature becomes higher, it may not be used.
