Description

[Detailed description of the invention] In the present invention, decorative plywood 3 is pasted on both sides of a core material 2 having a convex cross-section having a protrusion 1 at the center of the upper surface, and the edges of both decorative plywood 3 are attached with the protrusion. An opening 5 is formed in the center of the door using a frame material 4 which is bent toward the side to form an inclined part 3a and the tip of the protrusion 1 protrudes from the tips of both inclined parts 3a. Two picture frames 7 that sandwich the glass plate 6 disposed on the frame member 5 are fixed to the protruding parts of the protruding strips 1, and the outer peripheral edges of both picture frames 7 are brought into contact with the inclined parts 3a of the frame material 4, respectively. The purpose is to eliminate the need for dimensional adjustment between the opening provided in the center of the door and the frame, and to expose the cut end of the decorative plywood that makes up the frame material through the opening. Our goal is to provide you with a door that doesn't exist.

Conventionally, in a door A having a plurality of openings 5 in the center of the door and a glass plate 6 fitted into each opening 5 via a frame, as shown in FIG. The situation was as shown in Figure 2. However, in the case of such a mounting structure, it is necessary to approximately match the dimensions of the opening 5 and the frame 8, and if the machining accuracy of the opening 5 and the frame 8 is not high, it may be necessary to plan the actual alignment. There was a problem that it was not suitable for mass production. In addition, since the cut end 3b of the decorative plywood 3 constituting the frame material 4' and the core material 9 are often not flush due to manufacturing errors, providing a notch 10 on the outer peripheral edge of the frame 8 can eliminate manufacturing errors. I was beginning to absorb this. However, in this case, a gap is created between the picture frame 8 and the frame material 4, and the cut end of the decorative plywood 3
There was a problem that b was exposed and became unsightly.
The present invention has been made in view of the above points.

Examples will be described below using figures. Third
The figure and FIG. 4 show an embodiment of the present invention.
4 is a frame material, and the frame material 4 is made up of a core material 2 having a convex cross-section and a protrusion 1 at the center of the upper surface, and decorative plywood 3 attached to both sides of the core material 2, so that both decorative plywood One edge of each of the protrusions 3 is bent toward the protrusion 1 to form an inclined portion 3a, and the tip of the protrusion 1 protrudes from the tips of both inclined portions 3a. In the embodiment, another core material 9 is attached to the other edge of both decorative plywood boards 3.
A hollow frame member 4 arranged with a frame member 4 is used as a vertical stile and an upper and lower stile of the door, and a frame member 4' with a core member 2 arranged on both ends of decorative plywood 3 is used as a horizontal frame member. 7
is a picture frame, which holds a glass plate 6 that is fitted into an opening 5 formed in the center of the door using frame members 4 and 4'; The two picture frames 7 are fixed to each other with wood screws 12. At this time, the outer peripheral edge of the frame 7, that is, the corner of the notch step 7a provided on the outer peripheral surface of the frame 7 comes into contact with the inclined part 3a of the decorative plywood 3.

As described above, the present invention involves attaching decorative plywood to both sides of a core material with a convex cross section and having a protrusion in the center of the upper surface, and bending and tilting the edges of both decorative plywood toward the protrusion. An opening is formed in the center of the door using a frame material in which the tips of the protrusions protrude from the tips of both inclined parts, and two pieces of glass plate arranged in the opening are sandwiched. The picture frame is fixed to the protruding part of the above-mentioned protrusion, and the outer peripheral edges of both picture frames are brought into contact with the sloped part of the frame material, so that the picture frame is overlapped with the sloped part of the decorative plywood. So,
The advantage is that the cut end of the decorative plywood is not exposed at the opening, and by effectively utilizing the spring back of the bent portion of the decorative plywood, there is no gap between the picture frame and the sloped portion of the decorative plywood. Furthermore, since manufacturing errors in the frame can be easily absorbed by this inclined portion, it is not necessary to correct manufacturing errors by matching the actual item as in the conventional example, and there is an advantage that mass production is easy.
