Description

Detailed Description of the Invention Industrial Field This invention relates to doors.

2. Description of the Related Art Conventional doors are, as shown in Japanese Utility Model Laid-Open No. 59-893, a vertical-horizontal frame combination body in which a decorative material is joined on both sides,
It consists of an end plate that fills the required number of holes formed by the combination of the frame combination and has a decorative material bonded on both sides, and the peripheral edge of the end plate is inside the groove provided in the vertical and horizontal frame combination. It is inset.

Since the conventional door has the above-mentioned structure, it is necessary that the peripheral edge portion of each end plate and the groove of the vertical-horizontal frame combination body are exactly aligned with each other. Therefore, processing accuracy is required and
It took time to manufacture the door itself.

Therefore, the present applicant has made it possible to use a material that does not require the processing precision as in the above-mentioned conventional example and can reduce the weight and the cost of the door, and further, the door can be manufactured easily and efficiently. Was proposed first.

This proposed door includes a core plate, a vertical-horizontal frame member combination body having a required thickness bonded to both sides of the core plate, and a bottom plate having end plate fitting holes bonded to one surface of each of the frame member combinations. A base plate, an edge plate joined to at least left and right side surfaces of the four side surfaces of these joined bodies, an end plate fitted into a fitting hole and joined to both side surfaces of a core plate, and a flat peripheral edge portion of the end plate. A pressing member that is stacked on top of it and presses it down, and a decorative material that is bonded to one side of both base plates, the side edge surfaces of both edge plates that are flush with this, and the flat surface of the pressing member. It is a thing (Practical application 1-53712).

However, the above-mentioned door still has the following problems. This problem will be described below with reference to FIG. 7 showing a part of the proposed door.

Generally, between the vertical and horizontal frame member combination body (32) and the end plate (37), it is assumed that an error will occur in processing accuracy.
The door is designed so that there is a gap (S ₁ ) of about 2 mm. When manufacturing the door, the pressing member (39) is pressed by a press to bond the end plate (37) to the core plate (31) with an adhesive, and at the same time, press the holding member (39) to the end plate (37).
Is joined to the flat peripheral edge (38). However, when the door is actually manufactured, the gap may be almost eliminated due to an error, while it may be larger than the designed gap size. As a result, the frame member combination body (3
The lower corner of 2) side may fall into the gap (S ₁ ). When there is such a depression, the pressing member (39) inclines outward and downward, so when the decorative material (41) is bonded from the base plate (34) to the flat surface (40) of the pressing member (39), The decorative material (41) is not securely joined to the pressing member (39). Therefore, a dimple is formed in the decorative material (41) near the boundary between the base material (34) and the pressing member (39),
If the decorative material (41) is a decorative veneer, cracks may occur. In addition, the joint between the pressing member (39) and the end plate (37) has a mouth-opening condition, which impairs the appearance of the door.

An object of the present invention is to provide a door having the advantages of the above-mentioned proposed door and solving the remaining problems.

Means for Solving the Problems In order to achieve the above object, the door according to the present invention is
A core plate, a vertical and horizontal frame member combination body having a required thickness joined to both sides of the core plate, a base plate joined to each one side of both frame member combination bodies and having an end plate insertion hole, and these An edge plate joined to at least both left and right side surfaces of the four side surfaces of the joined body, an end plate fitted into a fitting hole and joined to both side surfaces of the core plate, and a flat peripheral edge portion of the end plate superposed on it. And a decorative material bonded to one side of each of the two base plates, the side edge surfaces of both edge plates that are flush with the base plate and the flat surface of the press member, and the end plate is a frame member. The area is smaller than the fitting hole so that a space can be maintained between the frame and the combination body, the leg member is provided on the inner surface of the frame member combination body in the pressing member, and the leg portion is composed of the frame member combination body and the end plate. It is interposed between and is closely attached to the core plate.

For the core plate, a material having rigidity that helps shape the door such as plywood, laminated wood, and medium-quality fiberboard is used. For the frame member, it is preferable to use a low specific gravity material such as balsa, paulownia, cedar, and cypress in order to reduce the weight of the door, and to use a low-grade material in order to reduce the cost of the door. A medium fiberboard, thin particle board, thin plywood, resin-impregnated paper or the like is used as the base plate, but the medium fiberboard is suitable. The decorative material is preferably a decorative veneer.

Operation Since the door according to the present invention has the above-described structure, the end plate may be simply joined to the core plate. Also, since the vertical-horizontal frame member combination is entirely covered by the base plate, when joining the decorative material on the surface, there will be gaps, recesses, or movements due to the joints of the frame members on the decorative surface. It is also possible to use low specific gravity materials, low grade materials and materials with some defects in the frame member combination,
Further, it may be spliced in the middle of the length, and joint processing may be omitted. Since the vertical-horizontal frame member combination body is used as a pair through the core plate, the thickness of each combination body may be necessarily thin. Further, when a decorative veneer is used as the decorative material, it is possible to prevent the veneer from cracking by using a non-directional material such as a medium-quality fiberboard for the base plate. Further, since the edge plates are joined to at least the left and right side surfaces of the four side surfaces of the joined body of the core plate, the vertical and horizontal frame member combination body, and the base plate, they are joined to the left and right side surfaces of the door which are visible when the door is opened and closed. Overlapping eyes will not be exposed. Further, since the decorative material is bonded to one surface of each of the base plates, the side edge surfaces of both edge plates that are flush with the base plate, and the flat surface of the pressing member, the seams of the base plate, the edge plate and the pressing member are not exposed. It will be.

The end plate has a smaller area than the fitting hole so that a space can be maintained between the end plate and the frame member combination body, the pressing member is provided with the leg portion on the inner surface of the frame member combination body, and the leg portion is combined with the frame member combination body. Since it is interposed between the body and the end plate and brought into close contact with the core plate, when the pressing member is pressed by the press,
The force is directly transmitted to the core plate.

Embodiment An embodiment of the present invention will be described below with reference to the drawings. A door shown in FIGS. 1 to 3 has a core plate (1) and a required thickness joined to both surfaces of the core plate (1). A vertical and horizontal frame member combination (2), a base plate (4) bonded to one surface of each of the frame member combinations (2) and having an end plate fitting hole (3), and these bonded bodies ( The edge plate (6) joined to both left and right sides of the core plate (5), the end plate (7) fitted into the fitting hole (3) and joined to both sides of the core plate (1), and the end plate (7). ) A pressing member (9) which is superposed on the flat peripheral edge (8) and presses the flat peripheral edge (8), one side of each of the two base plates (4), and side edges of both edge plates (6) which are flush with the one side. Face and the decorative material (1) joined to the flat surface (10) of the pressing member (9)
1) and the end plate (7) is a frame member combination body (2)
Has a smaller area than the fitting hole (3) so that a space can be maintained between them and the pressing member (9) is provided with a leg portion (12) on the inner surface of the frame member assembly (2). (12)
Is interposed between the frame member combination body (2) and the end plate (7) so as to be in close contact with the core plate (1).

In the above, the edge plate (6) is present only on both left and right side surfaces of the joined body (5) because the upper and lower side surfaces are invisible, but of course, the edge plate (6) is joined to these surfaces. May be.

The frame member combination (2) consists of the required number of vertical frame members (2a).
And a required number of horizontal frame members (2b) are combined. The end plate (7) has a decorative material (7
b) is joined.

There is a gap (S ₂ ) between the leg portion (12) of the holding member (9) and the end plate (7), which is subject to dimensional error.
The pressing member (9) is made of peeling material and has a flat surface (10).
A decorative curved surface (13) is formed on the surface except for.

FIG. 4 shows a modification of the pressing member. The holding member (19) of the same figure includes the first part including most of the flat surface (20) and the leg portion (12).
The second member (19b) includes the member (19a), the rest of the flat surface (20), and the decorative curved surface (13), and both are integrated via an adhesive. Since the second member (19b) has the decorative curved surface (13), a peeling material is used for this. Since the first member (19a) is covered with the decorative material (11) and is not exposed, a low-grade material, a medium-quality fiberboard, a parallel plywood, etc. are appropriately adopted and used for cost reduction. A medium fiberboard is suitable because it has good cut surface and is less likely to cause warp stress. It is desirable that the first member (19a) and the second member (19b) are not only simply bonded but also joined together by tongue-and-groove or phase inversion. Due to this combined use, no gap is generated between the first member (19a) and the second member (19b) even if a warp stress is generated in the peeling material second member (19b). Bonding between the holding member (19) or the holding member (9) of the above embodiment and the frame member combination body (2) is also performed by adhesion.
It is better to use it together with tongue-and-groove and jointing such as phase inversion.

FIG. 5 shows another modification of the pressing member. The pressing member (49) in the same figure includes a first member (49a) having a rectangular cross section including most of the flat surface (20) and substantially half of the leg portion (42), and a flat surface (2
0) and a second half of the leg (42) and the second member (49b) including the decorative curved surface (13), both of which are integrated via an adhesive. .
The material of each of the first member (49a) and the second member (49b) includes the first member (19) of the holding member (19) shown in FIG.
The same materials as a) and the second member (19b) are used.
In the case of the pressing member (49), the width of the leg portion is relatively wide, but the pressing surface is relatively narrow.

FIG. 6 shows a modification of the door form, and in the figure (17)
Is a mirror plate, (21) is a decorative material, and (29) is a holding member.

Effect of the Invention According to the door of the present invention, since the end plate is simply joined to the core plate, the end plate fitting groove as in the prior art is unnecessary, and therefore, the processing accuracy is not required. In addition, the appearance of the door can be finished beautifully because there are no gaps, recesses, or movements due to the joints between the frame members on the decorative surface. Further, it is possible to use a material that can reduce the weight of the door or a low-grade material in the combination of the vertical and horizontal frame members, and to reduce the manufacturing cost of the door itself. When the door is opened and closed, the edges of the joint are covered with edge plates on the left and right sides of the door that are visible, and the seams of the base plate, edge plate and the pressing member are covered with a decorative material. Good.

Furthermore, the legs of the presser member are in close contact with the core plate, and when the presser member is pressed by the press, the force is directly transmitted to the core plate, so it is guaranteed that the flat surface of the presser member is always flush with the base material. Therefore, there is no risk of dents or cracks in the decorative material near the boundary between the base material and the pressing member, and the overlapping seam between the pressing member and the end plate may be open. Absent.
