Description

[Detailed Description of the Invention] This invention relates to a shoji slip-off prevention device for attaching the upper frame of a shoji opening.

Conventional retaining devices are known in which a threaded member is screwed directly into a screw hole provided in the upper frame or with a U-shaped spring interposed between them. If the amount of screwing is too large, it will hit the top of the opening, making it impossible to screw in. Also, because the distance between the top of the upper frame and the top of the opening is narrow, there is a limit to the range of height adjustment, and the upper frame is too thick. Because it was thin, the thread in the screw hole could not be cut sufficiently, and there were problems such as the stability of the male thread member (chip) and the screw hole (wearing out) for a short period of time.

In order to address the above-mentioned conventional problems, this invention uses a male threaded member and a female threaded member to prevent these members from protruding above the upper frame, and allows for a wide range of height adjustment. This paper proposes an easy-to-install shoji shoji removal prevention device with excellent stability and durability.

Embodiments of this invention shown in the drawings) To explain in more detail, the detachment prevention device shown in FIG. A removal stopper 5 having a nut-shaped internal thread is screwed into this, and by rotating the removal stopper 5, the height can be adjusted according to the height of the shoji 6.

FIG. 2 shows a modification of FIG. 1, in which a flange 7 is provided at the upper end of the fixing member 3, and both sides of the flange 7 are connected to the rail 2, for example.
It is inserted between the tongues 8, 8 that protrude oppositely from the base of 2 and the lower surface of the upper frame 1, and can be easily fixed without using screws by bending and tightening the tongues 8, 8. It has been made possible.

In this case, the fixing member 3 can be fixed more reliably by providing recessed portions in both portions of the flange 76 and bending the tongue pieces 8 at these portions and tightening them.

FIG. 3 similarly shows a modification of FIG. 1, in which a locking flange 7 is provided at the upper end of the fixing member 3, and locking protrusions 9 are provided on both sides of the fixing member 3, for example, protruding from the bases of the rails 2, 2. 9 and the lower surface of the upper frame 1, screw the screw 10 into the screw hole provided in the center of the fixing member 3, and press its tip against the lower surface of the upper frame 1. By doing so, this is used as a reaction force. A downward pressing force is applied to the flange 7, thereby locking the protrusions 9 on both sides.
, 9 is fixed to the upper frame 11c.

In this case, since a pressing force is applied to the flange 7 via the screw 10, it is preferably reinforced with ribs 11 or the like.

The fixing member and the stopper are mainly molded from synthetic resin, but the stopper may be made of synthetic resin with a nut inserted.

In addition, the retaining device of this invention can be used not only for convex rails but also for concave groove rails, but when installed between convex rails and used for sliding doors, the retainer for the inner and outer shoji can be used for one time. In this case, it is sufficient to provide the fixing member in at least two places on the upper frame.This invention consists of the above-mentioned configuration, and the fixing member having the male thread is fixed to the upper frame, and the other member is attached to this. Because it is screwed in, the threaded part does not protrude above the upper frame and hit the top surface of the opening when adjusting the height, allowing a wide range of height adjustment and making it possible to adjust the length and diameter of the threaded part. It can be large in size, has a structure with excellent stability and durability, is extremely easy to install, and can be easily adjusted by pinching it with your fingers without using a screwdriver.
