Description

[Detailed description of the invention] This invention mainly relates to the connection part of the fittings that connects the vertical stile and the horizontal stile.

It is generally known that when trying to improve the strength of a shoji door against wind pressure, the estimated dimensions of the shoji door should be increased.

By the way, the upper and lower horizontal stiles that make up the shoji door fit into the upper and lower frames that are fixed to the building frame, so there is no need to increase their strength that much, but the vertical stiles can withstand wind pressure. bend.

Therefore, in order to reduce the material cost and weight and improve the strength of the shoji door, it is conceivable to increase the expected dimension C of the vertical stile and to decrease the expected dimension of the horizontal stile (see Figure 9).

However, when trying to connect a vertical stile with a large estimated dimension C and a horizontal stile with a smaller estimated dimension using screw members, etc.
As shown in the figure, the walls on both sides of the stile widen.

This is because if you try to connect the vertical stile and the horizontal stile with a screw member, you will have to rotate the screw member, and as a result, the horizontal stile will push out the side walls of the vertical stile (see Figure 8). .

As mentioned above, if the walls on both sides of the vertical stile widen, the shoji screens will come into contact with each other, causing trouble in sliding the doors, and the holding of glass doors etc. will become unstable.

Therefore, this idea was devised to solve these drawbacks, and it is a fitting that prevents the side walls of the vertical stile from widening even if a horizontal stile is inserted into the vertical stile and connected with screw members. Its main purpose is to provide a connection.

This invention will be explained below based on embodiments shown in the drawings.

First, the connecting part of the fittings according to this invention is composed of a vertical stile 1, a horizontal stile 2, a reinforcing wall 4, and a screw member 7.

The vertical stile 1 has a substantially U-shaped cross section, and the end portion 3 of the horizontal stile 2 is inserted from the opening side thereof.

By the way, the projected dimension C of the vertical stile 1 is wider than the projected dimension of the horizontal stile 2 in the shoji A.

Next, on the inside of the base of the vertical stile 1, there are reinforcing walls 4 at both corners.
4 are arranged.

The reinforcing walls 4, 4 are formed integrally with the sliding piece 5 on both sides of the sliding piece 5, as shown in FIG. 4, FIG. 5, and FIG. 6.

By integrally forming it in this way, material costs can be saved.

Thus, the vertical stile 1 and the horizontal stile 2 are connected at a substantially right angle so that the end portion 3 of the horizontal stile 2 fits between the reinforcing walls 4, 4.

That is, screw the screw member 7 from the outside of the base surface of the vertical stile 1,
Vertical stile 1 and horizontal stile 2 are connected.

In the above configuration, how to connect the vertical stile 1 and the horizontal stile 2 will be described.

First, explanation will be given with reference to FIG.

A reinforcing wall 4.4 having sliding pieces 5 integrally formed thereon is disposed at both corners of the inner side of the base surface of the vertical stile 1.

Next, the horizontal stile 2 is inserted into the vertical stile 1 from the opening side.

The end portion 3 of the horizontal stile 2 will fit between the reinforcing walls 4, 4.

Next, the screw member 7 is screwed into the vertical stile 1 from the outside of the base surface, and is screwed into the horizontal stile 2.

At this time, the horizontal stile 2 attempts to rotate around the screw hole 8 as the central axis by the screwing operation of the screw member 7.

However, the side walls of the end 3 of the stile 2 are in close contact with the reinforcing walls 4,4.

Therefore, the reinforcing walls 4, 4 prevent the horizontal stile 2 from rotating around its circumference.

Therefore, due to the circumferential rotational movement of the horizontal stile 2, both side walls 9, 9 of the vertical stile 1
will not be pushed out.

Therefore, the vertical stile 1 and the horizontal stile 2 can be connected by the screw members 7 without causing deformation to the side walls 9, 9 of the vertical stile 1.

Thus, this invention has the above-mentioned configuration, but according to the joint part of the fittings according to the invention, the horizontal stile is inserted into a vertical stile whose estimated size is larger than that of the horizontal stile, and both frames are connected with screw members. Even if they are connected, there is no risk of pushing the walls on both sides of the stile apart.

Therefore, there is no problem in sliding the shoji, and the holding of the glass door does not become unstable.

Therefore, the practical value of this idea is extremely high.
