Abstract

PURPOSE: To prevent warps or the like, by providing a core material within a wooden material which is longitudinally thin as a whole and has a section composed of wooden chips, wooden fibers, etc., and coating the surface with a decoration member. CONSTITUTION: A recessed part to fit a cross core material 2 is cut on one side face oppositely positioned, of two wooden fiber boards having a middle specific gravity and the cross core material 2 made of aluminum is inserted in the recess. The recessed face of the other wooden fiber board 1a is turned downward to laminate it on the wooden fiber board 1b. And then this block is cut to form a columnar shape. A grooved line 4 is longitudinally cut and the surface is coated with a decoration member 3. The joint of decoration members 3 is buried in the grooved line 4. Accordingly, the joint of decoration members becomes inconspicuous and hence, a high-grade appearance can be provided.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a handrail member.

[0002]

2. Description of the Related Art Wooden handrail members are generally manufactured by a method in which a laminated member is formed in a longitudinal direction into a desired circular or elliptical cross-section.

[0003]

However, although the laminated wood is expensive, it does not have a high-class appearance as if it was machined entirely from one tree. Furthermore, since the natural wood is simply cut, the bending strength was relatively strong, but there was a concern that warpage might occur due to changes in the surrounding humidity and the like. An object of the present invention is to obtain a handrail member having a uniform and high-grade appearance by using an inexpensive material.

[0004]

[Means for Solving the Problems] The above problem is that the whole is thin in the longitudinal direction and has a core material inside a wood material composed of wood chips, wood fibers, etc., the surface of which is covered with a decorative material. A handrail member having a structure, and a recess for mounting a core member on one surface of a wooden board made of two pieces of wood or wood fibers facing each other are formed, and then the core member is fitted into this recess. The present invention is a solution for a handrail member manufacturing method characterized in that two wood boards are laminated and adhered to each other, and then a cross-sectional shape is formed into a desired shape in the longitudinal direction to be thin, and a decorative material is adhered to the surface by coating. It

[0005]

According to the present invention, since a wood material made of wood chips, wood fibers, etc. is used, a handrail member of good quality can be obtained in which warpage or the like is unlikely to occur because the entire interior is homogeneous. In addition, since it has a core material inside, it is possible to impart bending strength similar to that of laminated wood. Further, since the groove is formed in the longitudinal direction and the seam of the decorative material is embedded in the groove, the seam of the decorative material is not conspicuous, and a high-class appearance as if cut from a single tree can be given. .

1 is a cross-sectional perspective view of a handrail member. The whole has a columnar shape in the longitudinal direction, and the cross-sectional structure is wood fiber 1
Has a cross-shaped core material 2 made of aluminum inside the
It has a structure in which the surface thereof is covered with a decorative material 3 made of a decorative veneer. Then, the groove 4 is formed at a predetermined position in the longitudinal direction, and the seam of the decorative material 3 is buried in the groove 4.

The cross-sectional shape is usually cylindrical in consideration of the ease of gripping as a handrail, but it is not limited to an elliptical shape and various other shapes. Although the cross-shaped core 2 is strong against bending, a flat plate or a column-shaped core may be used, and when the bending strength is not particularly required, the core may not be a cross-shaped core. Further, as the material thereof, metal such as steel and aluminum and synthetic resin such as FRP and ABS can be used. The wood material 1 is preferably made of wood fiber because it has a good balance of workability, strength, and weight, but hard boards and particle boards can also be used. The decorative material 3 coated on the surface may be a decorative veneer, a printed decorative paper, a vinyl chloride resin sheet having an uneven surface, or the like. When a decorative veneer is used, it is advisable to apply a synthetic resin paint after coating to improve durability and the like.

Next, an example of the manufacturing method will be described. First,
Two recesses 5 for inserting the cross-shaped core material 2 as shown in FIG. 2 are cut into several places with a cutter on one surface of each of the two medium-density wood fiberboards 1a and 1b having a thickness of 18 mm, which face each other. Next, one wood fiber board 1a is made to face the processing surface of the concave portion 5 upward, and the cross-shaped core material 2 made of aluminum is fitted into the concave portions 5 at several places. An adhesive or the like may be used when the core material 2 is fitted, but it is usually unnecessary. Then, another wood fiber board 1b is laminated on the wood fiber board 1a with the processing surface of the recess 5 facing downward, and one block is formed into a plurality of pieces as shown in FIG. To do. At this time, an adhesive is required, and melamine resin, phenol resin, urea resin or the like is used. Next, the dividing block A is processed into a columnar shape by a molding machine (FIG. 4). At this time, the groove 4 is machined at a predetermined position in the longitudinal direction.
Next, the surface is coated with the decorative material 3. As the decorative material 3, a decorative paper having a wood grain pattern printed on the surface is used and attached by a wrapping machine. Then, the seam (end portion) of the decorative paper is embedded in the groove 4 (FIG. 1).

[0009]

According to the present invention, since a wood material made of wood chips, wood fibers, etc. is used, a handrail member of good quality can be obtained in which warpage or the like is unlikely to occur because the entire interior is homogeneous. In addition, since it has a core material inside, it is possible to impart bending strength similar to that of laminated wood. Further, since the groove is formed in the longitudinal direction and the seam of the decorative material is embedded in the groove, the seam of the decorative material is not conspicuous, and a high-class appearance as if cut from a single tree can be given. .
