Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to the structure of a door panel in a folding door or the like.

[Background technology]

As shown in Fig. 1, the folding door consists of a pair of door panels A, A, folded and rotatably connected by a hinge 5, and a runner 6 and a pivot 7 provided at the upper and lower ends of each door panel A are connected to an upper rail 8 and a lower rail. The door panel A of such a folding door is formed so as to be attached to a rail 9 so as to be freely movable, and a plurality of upper and lower horizontal bars 2, 2, etc. are attached between the left and right vertical frames 1, 1, and furthermore, a plurality of upper and lower horizontal bars 2, 2, etc. stile 1,
It is formed by attaching a face material 10 such as plastic glass between 1 and 1. And regarding this, the second
As shown in the figure, a pair of horizontal bars 2 are used, front and back, and the horizontal bars 2 are installed between the vertical frames 1, 1 with a panel 10 sandwiched between the horizontal bars 2, 2. However, in this case, when the left and right end surfaces of the horizontal bar 2 are finished as flat surfaces that are exactly perpendicular to the surfaces as shown by arrow a in Fig. 2, the end surfaces of the horizontal bar 2 and the vertical Although it is possible to closely fit the inner surface of the stile 1 without creating a gap, it is actually difficult to finish the end face of the stile 2 to an accurately perpendicular flat surface in this way, and it is inevitable to It is unavoidable that the end face of the
If the surface is finished with an inclined surface that slopes obliquely inward toward the outside as shown by the arrow b in the figure, the end face of the horizontal bar 2 will be at its inner end and the inner surface of the vertical bar 1 in this part. Because of this, a problem arises in that a gap 11 is created between the end face of the horizontal frame 2 and the inner surface of the vertical stile 1.

[Purpose of invention]

The present invention has been made in view of the above points, and it is an object of the present invention to provide a door panel in which there is no possibility that a gap will be formed between the end face of the horizontal bar and the inner surface of the vertical bar.

[Disclosure of invention]

Therefore, the door panel according to the present invention is a panel A that is constructed by attaching horizontal bars 2, 2, . It is formed on a nearly vertical flat surface, and
The left and right end surfaces of the horizontal bar 2 are formed into inclined surfaces 3 that are inclined obliquely outward toward the outside, and the outer corner portions of the left and right end surfaces of the horizontal bar 2 are formed into acute-angled pieces 4 having an acute angle in plane section. The present invention is characterized in that the tip of the acute angle piece 4 is in contact with the inner surface of the vertical stile 1. With this configuration, the above object has been achieved, and the present invention will be described below. This will be explained in detail using examples.

The door panel A is formed with the same structure as that described above, but the horizontal crosspiece 2 has both end surfaces facing outward as inclined surfaces 3, 3 that are inclined obliquely outward as shown in FIG. The outer corner portions of both end faces have an acute-angled piece 4 whose planar cross-sectional shape is sharply pointed. Furthermore, tenon projections 14, 14 are protruded from both end surfaces of the horizontal beam 2. On the other hand, the inner surface of the vertical frame 1, which is a flat surface substantially perpendicular to the longitudinal direction of the horizontal frame 2, has a fitting groove 12 for fitting the side end of the panel 10, as shown in FIG. A mortise and tenon recess 13 is formed by enlarging the diameter of a part of the matching groove 12. When attaching the horizontal bars 2 to the vertical stile 1, the side ends of the panel 10 are fitted into the fitting grooves 12 of the vertical stile 1, and a pair of horizontal bars 2, 2 and the tenon protrusions 14, 14 of the horizontal bars 2, 2.
This is done by fitting the mortise into the tenon recess 13 as shown in FIG. At this time, the end face of the horizontal bar 2 and the inner surface of the vertical stile 1 contact at least one place, but since the end face of the horizontal bar 2 has an acute-angled piece 4 protruding from its outer surface, the tip of this acute-angled piece 4 Since the horizontal frame 2 always comes into contact with the inner surface of the vertical stile 1, there is no gap between the end face of the horizontal frame 2 and the inner surface of the vertical stile 1 in terms of appearance. Also, at this time, even if the vertical stile 1 is slightly inclined with respect to the end face of the horizontal stile 2,
Since the horizontal beams 2 are in line contact with each other through the acute angle pieces 4, there is no possibility that a gap will appear between the inner surface of the vertical stile 1 and the end surface of the horizontal beams 2. In the embodiment shown in FIG.
0 is attached to the door panel A only between the upper and lower horizontal bars 2, 2, and in this case, tenon protrusions 14, 14 are provided protruding from the center of the left and right end faces, and acute angle pieces 4 are provided on both the front and back sides. A provided horizontal bar 2 is used. The horizontal bars 2 at the upper and lower ends are upper horizontal frames 2a,
As the lower horizontal stile 2c, one similar to that shown in FIG. 6 can be used. In the embodiment shown in FIG. 7, the horizontal bars 2, 2 are bonded to the face material 10, so that it is not necessary to provide a tenon projection 14 on the horizontal bar 2 and to form a tenon recess 13 on the vertical stile 1. .

[Effect of idea]

As described above, according to the present invention, the inner surface of the rigid frame is formed into a flat surface substantially perpendicular to the longitudinal direction of the horizontal frame, and the left and right end surfaces of the horizontal frame are inclined outwardly. It is formed on an inclined surface, and the outer corners of the left and right end faces of the horizontal frame are formed into acute-angled pieces with an acute angle in plane section, and the tips of the acute-angled pieces are in contact with the inner side of the vertical stile. Therefore, when a horizontal frame is attached to a stile, the acute angle piece will always come into contact with the inner surface of the stile through line contact, and the end face of the horizontal frame will be finished to be exactly right-angled and exactly flat. This makes it possible to prevent gaps from appearing between the vertical stile and the horizontal stile in appearance without the need for difficult machining.
