Description

DETAILED DESCRIPTION OF THE INVENTION The present invention eliminates the need for three-dimensional construction by hand in the formation of a three-dimensional furniture body, and achieves three-dimensional construction by means of plywood of veneer, thereby forming the main body of a house in one step. The present invention relates to a method for molding.

Conventionally, in the case of a chair, for example, the main body part, that is, the frame part, is made up of three-dimensional KFi 1 side panels, which are cut out from 1 piece of bedding material, and then a piece of kasa lumber, 1 architrave material, etc. is assembled by making a handle hole, arranging a handle, etc. It was made three-dimensional by hand.

Also, to make it from plywood material, use one side material and a cap wood.

The architrave materials were made by molding, and these pieces were glued together by means of clasps, such as fins, to form the main body. That is, in FIG. 1, the main body l of the chair, which is three-dimensionally formed into a frame shape, is made of plywood, and the two side members i, z
', the cap timber 8, and the front and rear architrave timbers 4, 41 are each molded from plywood.

For example, these can be glued to the side panels s, s, and ' of the fin gorge seal joint i to create a three-dimensional structure.

Three-dimensional construction using such means not only requires a lot of effort, but also has the drawback that the strength of the clasped parts is relatively weak and durability is poor.

The present invention is characterized in that the furniture body is three-dimensionally molded without molding each member individually as described above, and without using claving means. In other words, wood cutting is performed on the Kogure board in the shapes that make up each three-dimensional shape, these are coated with adhesive, laminated and placed between multiple molds, each mold is used to press the laminated board, and then The adhesive is cured by heating, and after curing, it is taken out and cut into a predetermined shape to obtain a three-dimensional furniture body.

Next, an explanation will be given based on the drawings shown as embodiments of the present invention.

To form a rod-shaped chair body, for example, a chair body 10 as shown in FIG. 4, as a furniture body.

As shown in FIG. 1, each of the veneers 6 has a three-dimensional shape, that is, a square laminate 7. Back laminate 7' and base laminate 7#
According to each, cut the wood*C with different fiber directions. Next, a thermosetting adhesive is applied to each of these veneers 6, and several veneers are laminated into a desired shape so that the fiber directions alternate. As a result of this lamination, the fiber directions of each veneer are substantially perpendicular to each other as shown by the arrows in FIG. 3. The stacked laminate plates 7, 7' and 7' are then inserted into a three-dimensional mold.

FIG. 4 shows the molds 8.8', 8', and the molds 8.8', 8' are laminated [7, 7'].

7# is pressurized and further heated. Then, of course, there is a laminate 7 between each veneer 61. ? ', 7# Seki too! ! The adhesive hardens and adheres, and through these seven operations, it becomes a three-dimensional, one-piece piece in the plywood manufacturing process.

After the adhesive has hardened, take it out and mark it into the shape of the intended chair body L (shown in Figure 1). A continuous, integral three-dimensional body 10 without the joint joint 5 in 1 is obtained.

In the above embodiment, a laminated board is used in which the fiber directions are alternately stacked almost perpendicularly over the entire surface of the veneer. The wood grain surface appears on every other sheet.

Not only the painting material part but also the cap wood part or the part with the architrave is made so that the wood surface does not appear on the laminated surface.

That is, in FIG. 5, the front facing laminate F1. Back laminate 11
' and each 11 side material tz, ll of the base laminate 11',
18.18' and 14.14' are long veneers 17 for the side panels 12 and 12' whose length in the fiber direction includes the cap wood 15 and the front or rear architrave material 16; Short veneers 17' for the side panels 11 and 11 of the same length not included are stacked alternately, and the hat timbers 15 and front and rear architrave timbers 1 are stacked alternately.
6. The length of the fibers in one direction is 12. IB',
A long veneer 18 for capboard and architrave material having a length including 18, 18' and 14, 14'.

Short veneers 18' whose length does not include this are alternately stacked, and the long veneers 17 are also 18'.

17' is joined to 18 on the same plane and is also 1? F
At step i18, both sides are electrically connected to each other in terms of area, that is, left and right side members 12 to 14, overlapped every 11 to 14', and are pressurized and heated by molds 8.8' and 8'. Adhesively laminated together.

Therefore, one side member 12, 11.18.18' and 14.
14' and Kasa wood 15. On the laminated surfaces of the front and rear architrave materials 16, the end surfaces of the veneers do not appear, but appear as if they were seven pieces of wood, so the appearance is good and the painting can be beautiful.

Although the embodiments related to chairs have been described above, the present invention can also be applied to tables.

As mentioned above, the present invention is made of laminated wood veneers, so it has high strength and durability, and since the handle and the handle are laminated area joints without other joints such as finger joints, deformation and cracking are less likely to occur. , the curve configuration can be freely selected depending on the quantity, which leads to lower costs.
