Description

Detailed Description of the Invention

[0001]

[Industrial field of use] In a sleeve pulling sash, etc., a crescent stopper is used to prevent the crescent from directly colliding with the vertical frame or the vertical frame when the shoji is opened. The present invention uses this crescent stopper. It is related to the sliding door sash.

[0002]

Sliding door sashes, in which the fit-and-kill portion is applied to the external shoji and the external shoji are applied to the kill-and-kill portion, are well known without specific examples. When applying a fitting killing part to an external shoji, like a pulling sash, a crescent stopper for the left and right inner shoji (which prevents the crescent provided on the inner shoji from striking the vertical frame) is placed in the center of the upper and lower frames. It may get in the way and you have to remove it.

In addition, when the shoji screen is used as a fitting and killing part, the crescent stopper must be attached to the center of the upper and lower frames, and the travel of the shoji screen must be restricted by a restricting device.

In any case, in the sliding door sash, the crescent stopper and the restricting device for fixedly assembling the window frame of the shoji are formed of different materials, so that the fitting and killing part is the movable shoji and the movable shoji is the same. The preparatory work when converting to the fitting and killing part was complicated.

The present invention has been made with the object of providing a sliding door sash capable of diverting an external shoji screen into a killing portion as needed, by paying attention to the drawbacks of the conventional example and by a simple operation. It was done.

[0006]

A crescent stopper for an internal shoji is provided on an external shoji that can freely travel along a window frame, and a locking piece for engaging and disengaging the lower guide rail of the internal shoji is provided on the crescent stopper. Making things the basic means,
Specifically, a recessed portion is provided on the indoor surface side of the crescent stopper in the outdoor direction, and the base of the locking member having a hook-shaped locking piece on the free end side is rotated by a spindle on the side wall of the recessed portion. The guide rail of the inner shoji is provided with a receiving hole for engaging and disengaging the engaging piece, and more specifically, a virtual circle centered on the support shaft on the outdoor side surface side of the base of the engaging material. An arcuate surface along the arcuate surface is provided, and the inner wall of the recessed portion facing the arcuate surface is made of an elastically deformable material, and the projecting edge provided on the arcuate surface receives the locking piece. In the same manner as the first receiving edge that is locked when engaging with the stop hole, the projecting edge has the second receiving edge that is locked when the locking piece is disengaged from the receiving hole.

The crescent stopper may be provided on one or both of the upper frame and the lower frame of the shoji screen, or may be used in combination with another type of crescent stopper having no locking piece.
