Description

[Detailed Description of the Invention] The present invention relates to the structure of indoor fittings such as shoji screens, and more specifically relates to the connecting structure of vertical and horizontal frames in indoor fittings.

Vertical and horizontal stiles are generally connected by screwing into screw holes provided in one stile a tatsupin screw inserted through the other stile, but since this screw hole is integrally molded into the stile material, However, screw holes also exist in parts not related to the screwing, which requires extra material and is uneconomical.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to solve the above-mentioned drawbacks by making it possible to connect vertical and horizontal frames in indoor fittings without using screw holes or tatu pin screws.

In order to achieve this objective, the present invention is an indoor fitting in which upper and lower horizontal stiles are connected to left and right vertical stiles, and the horizontal stiles are cut out at predetermined locations to form cutout portions, and the vertical stiles are also The end portions are notched into a predetermined shape, and when these are connected, the locking pieces of the vertical stile are plastically deformed so that the pieces are locked to the side walls of the horizontal stile. The details of the present invention will be explained below with reference to the illustrated embodiments.

Figures 1 and 2 show the present invention as a horizontal stile and an upper stile 1.
The upper stile 1 has been implemented on the vertical stile 2, and as shown in FIG.
1, the wall thickness 2 of the web 21 is placed at a position corresponding to the web 21 of the vertical stile 2 to be connected to the upper stile 1.
A vertical notch 12 having a notch width 12t larger than 1t is formed.

On the other hand, as shown in FIG.
An extrusion-molded vertical stile 2 (Fig. 4 1) is formed with a cutout at the end thereof in a predetermined shape (Fig. 4 2) in order to connect it to a side stile (upper stile 1), and the upper stile The portion of the web 21 that fits into the notches 12, 12 of 1 is left to form an engaging portion 22, and the tip portion of the engaging portion 22 is used as a locking piece 23 independent of the others. In this example, the locking piece 23 forms an independent part that is structurally distinct from the others by forming a notch 24 at an appropriate position at the tip of the engaging part 22.

The vertical and horizontal frames 1 and 2, which are mutually cut out as described above, are locked together in the following manner. That is, the vertical and horizontal frames 1 and 2 are crossed while fitting the engaging parts 22 and 22 of the vertical frame 2 into the notches 12 and 12 of the upper frame 1, and then the locking pieces 2 of the vertical frame 2 are
3 and 23 in this example, and the locking piece 2
3 and 23 are engaged with the webs 13 and 13 of the upper frame 1. In this way, the vertical and horizontal stile connecting screw holes,
This will be done without the need for tuft pin screws.

In addition, in this specification, the meaning of "plastically deforming the locking piece 23" refers to the above-mentioned bending,
In addition to deformation using external force such as crushing, it also includes plastic deformation (e.g., strain deformation) caused by the locking piece 23 itself, such as deformation over time when a mold material is extruded.

In addition, FIGS. 5 and 6 show the connection state between the upper stile 1 on which the upper stile 4 is mounted and the vertical stile 2, and FIGS.棧5
This figure shows the connection state between the lower stile 3 provided with the stile 2 and the vertical stile 2. In these cases as well, the notch 1
2, 32, an engaging portion 22, and a locking piece 23 are formed, respectively. It goes without saying that cutouts may be formed in the upper and lower legs 4 and 5 as necessary.

As explained below, in the indoor fittings according to the present invention, the horizontal stile is cut out at a predetermined location to form a cutout part, and the end of the vertical stile is also notched into a predetermined shape, and when joining these, the vertical stile is cut out. Since the locking piece is plastically deformed, such as by bending, to lock the piece to the side stile, there is no need for screw holes in the stile, which is a component of the interior fittings. Not only does it contribute to material economy, but
Since the frames are connected to each other by simply bending the locking pieces, the work efficiency is improved. Note that the present invention is particularly applicable to indoor fittings, such as when applied to sliding doors, in which each frame is primarily connected and fixed by a member such as a sliding door core. It is something that can be effective.

Claims (1)

[Scope of Claim for Utility Model Registration] An indoor fitting comprising upper and lower horizontal stiles connected to left and right vertical stiles, characterized by meeting the following conditions (A), (B) and (C). (A) The horizontal stile has a notch width 12t larger than the wall thickness 21t of the web at a position corresponding to the web 21 of the vertical stile 2 to be connected to the horizontal stile on the front and rear stile side walls 11, 11. Forming vertical notches 12, 12. (B) The vertical stile 2 has its end cut out in a predetermined shape in order to be connected to the horizontal stile, and the web of the part that fits into the notch 12 of the horizontal stile remains to form an engaging part. 22, and the other end of the engaging portion is an independent locking piece 23. (C) In connecting the vertical and horizontal stiles, the locking piece 23 of the vertical stile 2 is plastically deformed to lock the locking piece to the stile side wall 11 of the horizontal stile.
