Abstract

PROBLEM TO BE SOLVED: To provide a manufacturing method for a wooden shutter blade reducing the material cost than before and capable of preventing a warp deformation and provide the wooden shutter blade. SOLUTION: In this manufacturing method, a plurality of wood plates with the prescribed length, width, and thickness are prepared as substrates. Glue is applied to the side faces of the substrates, and they are firmly pressed at a high pressure to form a wood lump. When the substrates are connected together, the substrates having the border lines of the annual rings on the end faces of the substrates in opposite directions are adjacently aligned. The wood lump is horizontally cut to the prescribed width to form a wooden blade with the prescribed thickness. When the surface of the wooden blade is polished with sand paper and coated with a paint, the wooden shutter blade is completed.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a method for manufacturing a wooden shutter blade and a wooden shutter blade.

[0002]

2. Description of the Related Art Conventionally, shutter blades are made of aluminum, plastic, wood, and the like. Among them, a wooden shutter is most popular. However, since wood cannot be easily obtained, the price is very high, and currently only two types are used: linden wood (Bass wood) and white wood (Ramin wood). These two types of wood fibers are straight striped and do not deform much after the manufacture of the thin blades of the shutter, making it an excellent shutter material. However, Shiraki (Raminwoo
d) is a tropical rainforest in Southeast Asia, so overcutting would degrade the global environment. Therefore, Europe,
Countries such as the United States have banned their logging, especially in European countries. Also, the cost of linden wood (Bass wood) is very high due to its small production area, and ordinary consumers cannot bear the cost.

The manufacture of conventional wooden shutter blades is as follows:
Simply cut the wood into a single board, the width of which is available in three types: 5 cm (2 inches), 3 cm (1 inch) and 1 cm (0.5 inches). Can be Although wooden shutter blades have an excellent feel and appearance, their manufacture has the following disadvantages.

That is, since a wooden shutter blade often warps due to a change in the temperature of the use environment, it is necessary to select an excellent straight stripe fiber structure before manufacture. Manufactured in linden (Bass wood) or white wood (Ramin wood). As mentioned above, the special choice of wood is very inconvenient and often costly to choose.

When a blade is manufactured using the above-mentioned wood, the above-mentioned wood has a firmer structural structure than ordinary wood, but has a width and a thickness in order to surely solve the problem of warping of the blade. It is necessary to set limits. According to experiments and tests, in order to resist warping, if the width of the shutter blade is 5 cm (2 inches), its thickness must be maintained at 3 mm or more. When the width specification is 3 cm (1 inch) or 1 cm (0.5 inch), its thickness must be maintained at 2.5 mm or more. That is, since the width of the blade is limited, a problem of material consumption occurs, and the material cost cannot be reduced.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a method of manufacturing a wooden shutter blade and a wooden shutter blade which can reduce the material cost as compared with the prior art and prevent warpage. Another object of the invention is

Embodiments of the present invention will be described below with reference to the drawings. As shown in FIG. 1, a method of manufacturing a wooden shutter blade according to an embodiment of the present invention includes the following steps. (a) Selection of material: As shown in FIG. 2, a trunk main body 101 of a tree trunk 100 is mainly selected as a basic material. The trunk body 10
Reference numeral 1 is composed of a core material 101a and a sapwood 101b, and a number of irregularly shaped annual rings are formed on an end face thereof.
When the tree trunk 100 is appropriately cut in the vertical direction, a large number of rectangular plate pieces are obtained. Each side of the plate piece is polished with sandpaper, and as shown in FIG.
To form The substrate 10 has two smooth longitudinal side surfaces 11 and side edges 12 and two smooth end surfaces 13 on which the contour of an annual ring composed of a fiber grain is provided. Lines are visible. (b) Arranged and pasted: As shown in FIG. 4, one layer of glue is applied to the side surfaces 11 of many substrates 10 and then
Each of the substrates 10 is extruded by a method of connecting and adhering the substrates 10 on which the fiber grain (the contour line of the annual ring) 3 is not adjacent to the substrate 10 and pressing strongly with an air pressure to form a wooden block 20. As in the present embodiment, it is best to arrange the substrates 10 such that the fiber grain (the contour line of the annual ring) on the end face 13 is connected in the opposite direction, thereby obtaining the best resistance effect against warpage. Can be (c) Cutting work: in the direction perpendicular to the bonding surface of each substrate 10,
When the wooden block 20 is cut laterally with a predetermined width w, a wooden blade 30 having a predetermined thickness is obtained as shown in FIG.
The wooden blade 30 is polished with sandpaper to form a smooth surface.
Holes are formed at both ends of the “0” to form a through hole 31, and a rope is provided through the through hole 31. (d) Painting operation: When a layer of paint is uniformly applied to each surface of each wooden blade 30 and dried, a required wooden shutter blade is obtained.

The method of manufacturing a wooden shutter blade and the wooden shutter blade of the present embodiment have the following advantages. (1) In the manufacturing process of arranging and sticking the substrates 10 of the present invention, since the fiber of the material does not exhibit a linear fiber, after being cut, the stress and the fiber significantly reduce the outside or middle. It assumes a state of being bent to the side. Therefore, the fiber grain (the contour line of the annual ring) of the end face 13 of the substrate 10 is connected in the opposite direction so as to be released from the stress (bending). This arrangement method can prevent a state in which the shutter blade is warped by using a direction of the fibers of the substrate 10 to generate a stress canceling action. Therefore, it is not necessary to designate a specific wood with the basic material selected in this embodiment, and a blade having an effect of resisting a warped state can be obtained mainly by appropriately arranging the grain of the fiber. In the case of manufacturing, a basic material can be easily obtained, and the effect of cost reduction can be achieved. (2) The shutter blade manufactured by the above-described method naturally obtains a decorative pattern made of fibers and a beautiful appearance on the surface in the long axis direction, and further connects the substrate 10 having no annual ring contour line adjacent thereto. Since the shutter blade is manufactured by cutting, the effect of resisting the warpage of the shutter blade itself is excellent. Further, since the thickness of the shutter blade can be reduced, the volume and cost can be saved. In actual production, if the width of the shutter blade is about 5 cm (2 inches), its thickness is 2.3 m.
m and the width of the shutter blade is about 1 cm
(0.5 inch), the thickness is set to 1.6 mm or less.

As described above, the present embodiment cuts inexpensive wood, such as cedar, pine, and other wood having a grain-like or wave-like shape, into flakes, and is made of a material and an easily deformable material. In order to address the problem of conventional shutter blades made from qualified materials, a thin shutter blade that does not deform is manufactured by a special processing method, that is, a process of arranging, pasting, and cutting. The advantages of the shutter blade are light, thin, beautiful, cheap, and easy to obtain materials.Because it can use all cedar, pine, and other wood with a remarkable grain, it is natural according to the user's preference. You can choose one with the beauty of wood grain.
