Description

  The present invention relates to a blindfold mounted on a door replacement cover frame.

  In recent years, aluminum sash doors have rapidly become widespread, and replacement work for aging existing doors has been increasing. In this construction, after an existing door is removed, a replacement cover frame is mounted on an existing cover frame mounted on a wall, and a new door is mounted in the replacement cover frame. For example, in Patent Document 1, in order to easily incorporate a door after mounting a replacement cover frame, a suspension pin is provided on the cover frame, and a new door is temporarily suspended on the suspension pin. Yes. Since the cover frame for replacement is performed in an existing building, the shape and dimensions of the existing cover frame vary and are not rated. Therefore, when the replacement cover frame is mounted, a gap may be generated between the existing cover frame and the replacement cover frame. Therefore, a blindfold board is necessary to hide the gap. Conventionally, Patent Document 1 shows an example in which a blindfold plate is mounted in a construction in which a replacement cover frame is mounted.

  According to this, as shown in FIG. 5, the replacement cover frame 60 is mounted on the basis of the existing cover frame 70 embedded in the wall body 1. The replacement cover frame 60 has a front frame 61 and a rear frame 62 with respect to the front-rear direction of the door. The door 7 is inserted into the front frame 61, and the front surface of the rear frame 62 is an opening / closing stopper of the door 7.
