Description

  The present invention relates to a screen door fixing device, a screen door, and a sash for fixing the screen door to a window frame.

  Generally, a shoji is attached to a building opening so that it can be opened and closed with respect to a window frame fixed to the building opening, and a screen door is attached. Here, various types of screen door fixing structures for fixing the screen door to the window frame have been proposed.

  For example, in Patent Document 1 below, the left and right vertical fences of the window frame have projecting pieces protruding in the in-plane direction, and the screen door fixing pieces for fixing the screen door to the window frame are provided on the left and right vertical fences of the screen door, The screen door fixing piece is pivotally supported so as to be able to rotate in and out of the plane so as to be engaged with the protruding piece, and has a locking member having an operation portion at one end, and a biasing force that biases the locking member in the out-of-plane direction A screen door fixing piece including a member is disclosed.

  Moreover, in the following Patent Document 2, for the purpose of restricting the vertical movement of the screen door, a slip-off preventing member is rotatably provided at a corner piece arranged at the upper two corners of the screen door. At the time of installation / removal work, it was tilted forward (outside of the room), and if the screen door was installed, the above-mentioned retaining member was raised to be interposed between the outdoor side piece and the upper section screen of the small window frame. Are disclosed.

Japanese Patent Application Laid-Open No. 2002-266569 JP 2007-162378 A

  However, in the screen door fixing piece described in Patent Document 1, the screen door is fixed to the window frame by locking the locking member to the protruding pieces provided on the left and right vertical fences of the window frame. There is a problem that the protruding piece and the locking member protrude from the window frame and the appearance is impaired.

  Moreover, in the slip-off preventing member described in Patent Document 2, since the slip-off preventing member is tilted to the outdoor side of the screen door, the screen door must be attached and detached from the outdoor side, and workability is poor. .

  Therefore, the main problem of the present invention is to improve the appearance of the screen door and improve the workability of attaching and removing the screen door.
