Description

  The present invention belongs to the technical field of architectural shutters attached to openings such as entrances and exits of buildings and slats in architectural shutters.

  In general, this type of shutter for building is designed to open and close the opening by moving the shutter curtain while guiding it with the guide groove of the guide rail. In some cases, it is required to provide a wind-resistant mechanism so as not to escape from the guide rail in response to the generated strong wind. Therefore, conventionally, wind-resistant hooks are provided at the ends of the slats constituting the shutter curtain, and the wind-resistant hooks are locked to locking portions provided on the guide rails to prevent them from coming off. However, this not only increases the number of parts because a wind-resistant hook is required as a separate member, but also prevents the wind-resistant hook from becoming a hindrance when winding the shutter curtain, Has a problem that a step for attaching the wind-resistant hook to the slat is required.

Therefore, a retaining recess is formed by opening a punched hole at the left and right end portions inserted into the guide rail of the slat, and the hole edge of the retaining recess is formed on the inner surface of the guide rail as the slat is bent. A structure is known in which a slat is prevented from coming off from a guide rail by being locked in a protruding mohair pocket.
