2. Description of the Related Art Conventionally, a frame has a structure in which block-shaped members made of laminated material are juxtaposed in the longitudinal direction, and natural wood veneer plates are joined to the front and back sides of the blocks.

[0003]

The laminated material as described above has been artificially dried in advance and has a water content of about 10%, but it may expand and contract due to the influence of humidity thereafter. There is. On the other hand, since the roughness and the direction of the grain of each laminated material are different, there is a problem that the expansion and contraction rates are different. When such expansion and contraction occur, the surface property of the veneer plate is affected, and there is a problem that the aesthetic appearance is deteriorated.

In view of such circumstances, it is an object of the present invention to provide a frame that does not affect the surface even if the humidity changes.

[0005]

A first aspect of the present invention for solving the above-mentioned problems is a frame which constitutes a framework of a natural wooden door, and is a front and back surface of a frame main body to which block-shaped members of laminated materials are joined. The frame is characterized in that a buffer board is joined to the side and a natural wood board is joined onto it.

According to a second aspect of the present invention, in the first aspect, a natural wood member is provided at both ends in the longitudinal direction, and the natural wood member and the natural wood board are joined together. It is in.

A third aspect of the present invention is the frame according to the first or second aspect, characterized in that the buffer plate is a plywood.

A fourth aspect of the present invention is the frame according to any one of the first to third aspects, characterized in that the laminated material is made of a soft wood material.

According to the present invention, since the cushioning plates are joined to the front and back sides of the block-shaped members of the laminated material arranged side by side, and the natural wood board is joined thereon, the laminated material of the laminated material is changed. The partial expansion and contraction is absorbed by the buffer board, and the surface of the natural wood board is not affected.

Here, the laminated material means that a plurality of thin plates are laminated to artificially reach a predetermined water content, for example, a water content of 7 to 8.
% Dried, usually with a water content of 10 to 1
Used in 2% condition.

The frame main body of the present invention is constructed by joining block-shaped members of such laminated materials. In general, a column-shaped laminated material may be arranged and joined, and this may be cut into a column shape. However, it is preferable that the column-shaped laminated material is arranged and joined and further joined in a plurality of stages and stacked in a plurality of stages. A columnar piece whose direction is the longitudinal direction is used. The laminated material may be hard wood or soft wood, but it is particularly preferable to adopt the structure of the present invention when using soft wood that easily expands and contracts under the influence of humidity.

Here, the natural wood board means a veneer or a sawing board of natural wood, and for example, a board material of about 1 to 7 mm is used. The type of natural tree is not limited, and examples thereof include cedar, cypress, pine, zelkova, bay pine, bay hiba, hemlock, and cedar.

The natural wood member is a columnar member of natural wood, and has a thickness of, for example, about 10 mm to 30 mm.

In the present invention, the cushioning board is intended to absorb the expansion and contraction of the laminated material to reduce the influence on the natural wood board. That is, it is preferable that the expansion and absorption due to humidity be at least smaller than that of the laminated material, and preferably that the expansion and contraction hardly occur, and that the strength in the thickness direction is smaller than the strength of natural wood. That is, the laminated material is contracted and expanded so as to absorb the dimensional change due to the expansion and contraction of the laminated material so that the natural wood board is not affected. Generally, plywood may be used. The plywood is not particularly limited, but for example, veneer core plywood such as a cross-coated veneer or lauan plywood can be used. The thickness is the same as or slightly thicker than the natural wood board, and is, for example, about 1 mm to 10 mm.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described below based on an embodiment.

FIG. 1 is a sectional view showing a sectional structure of a frame according to one embodiment. As shown in the figure, in the frame 10 of the present embodiment, a buffer plate 13 is joined to the front and back sides of a frame body 12 to which a block-shaped member 11 of a laminated material is joined, and a natural wood board 14 is attached to the front and back sides. It is joined. Further, in the present embodiment, the front and back sides of the natural wood member 15 are provided at both longitudinal ends of the frame body 12 so as to be joined to the natural wood board 14. Here, the natural wood member 15 may be provided as needed, and may be provided on either one. If necessary, natural wood boards or decorative plywood may be provided on the upper and lower surfaces orthogonal to the front and back surfaces.

Here, the structure of the block-shaped member 11 of the laminated material is not particularly limited, and a column-shaped laminated material may be arranged and joined and the dimension in the longitudinal direction may be cut. It is also possible to use a product obtained by further laminating a plurality of layers joined together and then cutting them in the longitudinal direction and the initial juxtaposed direction.
However, even in this case, since the roughness and the direction of the grain are different, there is a problem that the expansion and contraction rates are different from each other. However, in the structure of FIG. 1, the buffer plate 13 is the block-shaped member 1
Since the dimensional change due to the expansion and contraction of No. 1 is absorbed, the natural wood board 14 is not affected.

In the present embodiment, lauan plywood having a thickness of 3 mm is used as the buffer plate 13, and bay pine sawing plate having a thickness of 2.3 mm is used as the natural wood board 14. The type of the natural wood board 14 is not limited, and it goes without saying that it may be a veneer.

FIG. 2 (a) shows a simplified structure of the block-shaped member 11 of the laminated material of the frame 10 of the present embodiment. The block-shaped member 11 is formed in the stacking direction of the creases, that is, in the direction of the arrow. Although it has the property of expanding, the surface of the natural wood board 14 is not affected because of the buffer board 13.

On the other hand, when the cushioning plate 13 is not provided, the natural wood board 14 is deformed due to the expansion and contraction of the frame body 12 of the laminated material, and when displayed extremely, the surface is uneven as shown in FIG. 2 (b). Become.

Such a frame 10 is used as a frame member of a wooden door, and one example thereof is shown in FIGS.

As shown in these drawings, the wooden door 20

A skeleton is constituted by the crosspieces 23 that connect the middle of the above, and an end plate 24 is fixed in a state of being fitted through a nest 25 in an opening formed by these.

Here, the vertical frame 21, the horizontal frame 22 and the crosspiece 23
Have basically the same structure as the frame 10 described above. Further, as the panel member, a glass plate or another decorative plate may be used instead of the end plate 24. In addition, the end plate 2
The frame 10 may be used on the frame 4 or a part of the decorative plate.

Further, as shown in FIG. 4 which is a sectional view taken along the line AA of FIG. 3 and FIG. 5 which is a sectional view taken along the line BB, the insert 25 has an end plate 24 as a panel member in the opening of the frame. And a panel member joint portion 25a for fixing the end plate 24 in a fitted state to one end side in the width direction, the horizontal frame 22 and the crosspiece 2.
3 or a vertical frame 21 and a frame joint portion 25b which is joined to the panel member, and both sides in the thickness direction of the panel member are decorative surfaces 25c.

The structure of the end plate 24 is not particularly limited, either.
In the present embodiment, a nesting joint portion 24b having a relatively thin peripheral portion is provided around a main body portion 24a made of panel plywood.

In the wooden door 20 described above, the influence of expansion and contraction of the frame main body to which the laminated materials are joined is absorbed by the buffer plate even if the humidity of the use atmosphere changes, and the vertical frame 21 and the horizontal frame 22.
And the smoothness of the crosspiece 23 is maintained.
