Description

DETAILED DESCRIPTION OF THE INVENTION TECHNICAL FIELD The present invention relates to a frame material used for manufacturing a flat panel, and more particularly to a composite frame material made of a wood material and a rigid material.

Prior Art and Its Problems Tables, doors, shelves, etc. are generally constructed in a flat panel type structure.

A flat panel is a frame body consisting of an outer frame that forms the outer periphery of the panel and an inner frame placed between the outer frames, and external materials such as boards or plywood are glued from the front and back sides of the frame. It is formed as a result. The flash panel formed in this manner has advantages such as being easy and inexpensive to manufacture and reducing the weight of the panel.

However, in conventional flat panels, wood is used for the outer frame, inner frame, etc. due to its excellent workability and adhesion to the outer surface material, so the frame material itself is Alternatively, it has the disadvantage that the surface of the outer material is deformed due to deformation due to the influence of humidity or the like. Such deformation of the frame material due to temperature or humidity cannot be solved by selecting the wood species or the dimensions, and tends to occur particularly in furniture-style kotatsu etc. that are subject to relatively large temperature changes.

Instead of the wooden frame material which has such drawbacks, deformation of the flat panel can be prevented by using a rigid material such as metal as the frame material. However, the dimensions of a flat panel vary widely depending on its use, and therefore the dimensions of the frame material used for it are not always of a fixed size. Since it is necessary to adjust the following, it is generally preferable to finish with wood processing only. In addition, using metal frame materials that require metal processing for panel manufacturing at the same time as wood at woodworking sites may cause explosions due to sparks during metal processing.
There have been cases of fires, making it extremely dangerous and impractical.

Therefore, we have developed a wooden adhesive surface that does not easily deform due to temperature or humidity, whose dimensions can be easily adjusted through wood processing in the same way as wooden frame materials, and which also has excellent adhesion to external materials. It has been desired to develop a frame material that has

OBJECTS OF THE INVENTION The purpose of the present invention is to overcome the drawbacks of conventional wooden frame materials as described above, and to provide a composite frame material that has workability and adhesive properties similar to those of wood and has extremely high rigidity. It is.

Summary of the Structure of the Invention The composite frame material of the present invention has a structure in which a core member made of a highly rigid material is sandwiched between wooden plate-like members and these are interconnected to form an integrated structure. There is.

Moreover, the structure of the present invention can also be made into a structure in which a wooden end member is connected to at least one end of the core member, if necessary.

DESCRIPTION OF EMBODIMENTS Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 shows a composite frame material 1 according to a first embodiment of the present invention, and this frame material 1 is made of a core member 2 made of a rigid material and a wooden material connected to both ends of the core member. The core member and the end member are sandwiched from both sides and connected to the upper and lower plate members 4 and 4', which are also made of wood material. It is preferable that the connection between each member be performed mainly by adhesive. Here, the term "rigid material" refers to a material having higher rigidity than wood materials, such as metal or ceramic. In addition, wood materials include wood, or materials made from wood or plant fibers such as plywood, particle board, fiberboard, etc., mainly using adhesives, and materials that are made mainly from plant fibers such as cardboard, cardboard, etc., and are equivalent to wood. It means a material that has workability and adhesiveness to wood. For these wood materials, for example, the thickness of wood, plywood, particle board, etc. can be adjusted by cutting or polishing, and the thickness of cardboard, cardboard, etc. can be adjusted by polishing or compression.

The core member 2 may also have any shape having opposing sides that provide contact surfaces with the plate members 4, 4'. FIG. 3 is a sectional view taken along a plane that crosses approximately the center in the longitudinal direction of FIG. 1, and in this embodiment, the core member 2 is shaped like a square pipe with a rectangular cross section. As shown in FIGS. 4 and 5, plate members 4c, 4'c, 4d,
It is also possible to arrange a core member 2c with a letter-shaped cross-section and a core member 2d with a hat-shaped cross-section between 4'd.

Next, referring to FIG. 2, there is shown a second embodiment of the composite frame material of the present invention, in which the frame material 1a is a plate-shaped core member 2 made of a rigid material.
a, end members 3a and 3'a made of wood materials connected to both ends of this core member, and upper and lower plate members that are integrally connected with these core members and end members in between. 4a and 4'a.

In the composite frame members of the first and second embodiments described above, plate members are connected on two side surfaces of a core member made of a rigid material, and end members made of a wood material are connected to both ends of the core member. However, plate members may be connected to three or more sides of the core member. In this case, the length of the composite frame member is adjusted by processing the plate member extending from the end of the core member. In any case, the lengths l, l' and heights h, h' of the frame members 1 and 1a shown in Figs. 1 and 2 are adjusted by ordinary wood processing means such as cutting, polishing, and compression. It is important to configure the system so that it can be used.

Therefore, depending on the application or to save the number of plate members, instead of providing plate members on the entire surface of the core member, a predetermined number of plate member pieces of a predetermined size are provided at intervals in the longitudinal direction or width direction. It is also possible to have a configuration in which the surface is partially covered.

Next, referring to FIG. 6, there is shown a flash panel 10 constructed using the composite frame material of the present invention as outer frames 11, 12, 13, 14 and an inner frame 15. To explain the case where such a flat panel is formed using the composite frame material 3 shown in FIG. 1, first, a composite frame material 1 of a predetermined length l is selected and both ends of each frame material are Cut it into a shape that fits the abutting portion shown by reference numeral 18. This cutting can be done if both ends of the composite member are made of only the end members 3, 3' and the plate members 4, 4', or only the wood material of the plate member 4,
Since it consists only of the 4' end, it can be easily done by ordinary woodworking means. Next, the frame material with both ends cut off is attached to the outer frame 11 in FIG.
12, 13, and 14. The abutting surfaces at both ends of each frame member are fixed with adhesive or staples 19. The frame material constituting the middle frame 15 is inserted into the thus assembled outer frame and is connected and fixed to the outer frame. When inserting the frame material as the middle frame, the distance between the outer frame bodies can be adjusted by cutting both ends or one end of the frame material 1. It is preferable that the joint surfaces of both ends of the middle frame 15 to the outer frames 12 and 14 be connected with an adhesive and further connected and fixed with staples 20.

Adhesive is applied to the surfaces of the plate members 4 and 4' of the frame material 1 shown in FIG. 17, the flash panel 10 is formed.

In this way, the composite frame material of the present invention is made rigid by a rigid material, and at the same time, the ends and upper and lower surfaces are made of wood material, so it can be easily processed by ordinary wood processing means without using special tools. It can be easily processed, and furthermore, the connection between the frame members or the connection between the frame member and the surface member can be easily performed using an ordinary adhesive or staple used for joining wood materials.

Next, a method for manufacturing a composite frame material according to the present invention will be explained with reference to FIG.

On the lower plate 31 constituting the lower plate member 4' of the composite frame material 1, a metal or other material having the cross section shown in FIG. Core member 3 made of rigid material
2 (in the illustrated example, 5 pieces) are installed at predetermined intervals, and then spacers 33, 33', which constitute end members 3, 3' made of wood material, are placed on both ends of each core member on the upper and lower side surfaces thereof. Apply adhesive and install. The spacers 33, 33' and the ends of each core member 32 are joined with adhesive as necessary. Next, the upper plate 34 constituting the upper plate member of the composite frame material 1 is adhesively fixed onto the core member 32 and the spacers 33, 33', thereby forming a preform 30 that will become the material of the composite frame material. . After this, the cutting lines 35a, 35
The composite frame material 1 can be formed by cutting and dividing the preform along lines b, 35c, and 35d.

Further, a preform can be manufactured by applying an adhesive to the upper and lower plate members 34, 31 and joining the core member 32 and end members 33, 33' by sandwiching them in a sanderch style manner.

Effects of the Invention As is clear from the above description, since the composite frame material of the present invention is made by joining a board member made of a wooden material to a core member made of a rigid material, it is easy to adhere to the face material of a flat panel. At the same time, it becomes possible to easily adjust the thickness of the frame material by processing the wood.

Further, since at least one end of the core member is made of wood material, the length of the frame material can be easily adjusted by wood processing means.
