Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wooden door used for entrances and interiors.

[0002]

2. Description of the Related Art Conventionally, when a vertical frame and a horizontal frame are joined, the joint shape such as a fitting or dowel structure is joined by using an adhesive, and polishing is performed so as not to cause a mesh or a step at the joining point. However, there is a wooden door obtained by a so-called post-coating finishing method, in which the joint surfaces are made flush with each other and then coating finishes such as sealing coloring, intermediate coating, and top coating are performed.

Further, one or both outer edges of the joint end surfaces of the frame component are cut off in advance so as not to come into contact with each other at the time of joining, panels are arranged, the frame component is assembled, and the frame component is assembled. There is a wooden door obtained by a method (Patent Publication No. 62-4513) in which the outer edges of the joint end faces are faced to each other to form a fine groove on the sakai surface of the butting portion, and then paint finish is performed.

[0004]

However, in the method in which the surface of the joint portion between the frames is ground to a flush horizontal surface and then the coating is finished, although the designability immediately after the coating is excellent, Due to repeated expansion and contraction of the wood during use, cracks are likely to occur in the coating film at the joint portion, and in particular, cracks occur due to drying, which has the drawback of deteriorating the appearance.

Further, the wood obtained by a method in which the outer edge surfaces are cut off in advance so that the outer edge surfaces do not come into contact with each other and then assembled, fine grooves are formed at the boundaries of the joining points, and then a finish is applied. The door has a thin groove on the boundary surface even if the wood at the butt portion of the frame component contracts during use, and it is not a level horizontal surface. There is no advantage.

However, since the outer edge is cut off without being too small, when the width of the groove is narrow, it is difficult to spread the paint sufficiently to the bottom of the groove in the painting process after assembling. In rainy weather with strong winds, in the case of an entrance door, there is a case where it gets wet with water, and water easily penetrates into the wood from the bottom and side surfaces of an incompletely painted groove and expands and dries easily, leading to cracking. was there.

As a method of preventing such a problem, it can be solved by preliminarily coloring and coating the bottom and side portions of the narrow groove before the assembling and joining of the frame members, but the number of coating steps increases, It required extra effort.

Further, since one or both of the outer sides is cut off without any dimension, the depth of the groove becomes the thickness of the cut-off position of the outer edge, and the groove becomes deeper. Therefore, the designability in relation to the groove width is improved. Was not always satisfactory.

That is, the object of the present invention is to make the cracks in the coating film inconspicuous and to alleviate the uncomfortable feeling of the joint portion due to the color difference of the material, without substantially impairing the designability and waterproofness of the joint portion. is there.

DISCLOSURE OF THE INVENTION The present invention has been made in view of such circumstances, and in the wooden door (1), the outer joint end of the frame component is cut to form a convex curved surface (7),
(9) and slopes (8), (10) and other cutting surfaces are formed, and the tip (7a) of the cutting surface of the frame component member,
The problem is solved by using a wooden door (1) in which (8a), (9a), and (10a) are joined while abutting each other, and the surface of the frame constituent member is covered with a coating film (15). be able to. Hereinafter, the present invention will be described with reference to the drawings.

【Example】

Example 1 FIGS. 1 and 2 are a front view of a wooden door (1) of Example 1 and a sectional view taken along line AA in FIG. The wooden door (1) of Example 1 is made of solid wood, and the vertical frame (2), the upper frame (3), the lower frame (4), and the middle rail (5) are frame components.
The end plate (6) is fitted, and the respective frame constituent members are fitted with each other by male and female, and are bonded and fixed with a dowel and a urea resin adhesive.

Each of the upper frame (3), the lower frame (4), and the middle bar (5) has a convex curved surface (radius of 6 mm) at the outer end of the frame constituent member at the joint with the vertical frame (2). 7) is cut, and by assembling so that the tips (7a) of the convex curved surfaces (7) abut against each other, a substantially V groove (1
2) has been formed.

After being assembled, the wide belt sander
The surface of the frame constituent member is covered with a coating film (15) by finishing the surface with bare wood, coloring the base, applying an intermediate coating and a top coating with a polyurethane resin paint.

Example 2 FIG. 3 shows a wooden door of Example 2 obtained by forming a slope (8) on the outer joint end of the frame component member, assembling it in the same manner as in Example 1, and applying a top coat. It is sectional drawing which shows the structure of the joint part of a lower frame and a vertical frame. When the thickness of the coating film of the wooden door of Example 2 is the same as that of the wooden door of Example 1, the paint is less likely to collect and cracks in the coating film are not noticeable.

Example 3 FIG. 4 shows that a convex curved surface (9) is formed while leaving a vertical surface (11) at the outer joint end of the frame constituent member, assembled in the same manner as in Example 1, and obtained by applying a top coat. It is sectional drawing which shows the structure of the joining part of the lower frame of a wooden door of the obtained Example 3, and a vertical frame. The wooden door of the third embodiment prevents the tip end (9a) of the convex curved surface (9) from being chipped.

Example 4 FIG. 5 shows that the outer joint end of the frame component is formed with a slope (10) while leaving a vertical surface (11), assembled in the same manner as in Example 1, and top-coated. It is sectional drawing which shows the structure of the joint part of the lower frame and vertical frame of the wooden door of Example 4. The wooden door of Example 4 prevents the tip (10a) of the slope (10) from being chipped, so that cracks in the coating film are not noticeable.

[0017]

Industrial Applicability The wooden door of the present invention has a cutting surface such as a slope or a curved surface formed by cutting the outer end of the joint portion of the frame structural members such as the vertical frame, the upper frame, the lower frame, the middle rail, and the bundle. To form a substantially V-groove on the surface of the joint by assembling so that the tips of the cutting surfaces of the frame constituent members abut each other, so that the inside of the substantially V-groove can be completely and easily coated. Therefore, it is possible to prevent material cracking due to water intrusion from the joint.

Further, in forming the approximately V groove, the depth is made shallower than the width so that the base colorant, the intermediate coating material and the top coating material are completely filled in the approximately V groove in the coating after the assembling. It can be applied, which facilitates polishing work such as intermediate coating.

Further, the V-grooves are formed in the joint portion in order to avoid defects such as cracks in the coating film at the joint portion caused by the contraction of the frame members and the like, and the occurrence of a step due to the difference in the contraction rate of the material. , These defects are not conspicuous and do not impair the appearance.

Further, since the surface of the joint portion is divided by the substantially V-shaped groove, the discomfort due to the color difference between the materials is alleviated and the design is improved as compared with the joint portion finished to be flush.

The cutting surface is not particularly limited to those in Examples 1 to 4 as long as it forms a substantially V groove when it is cut into a convex curved surface or a sloped surface and is joined, and it can be appropriately combined. .
