Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a wooden door used for entrances of buildings, etc.

(Prior art) In general, wooden doors for entrances of buildings, etc.
A frame made of frames, muntins, etc., with a mirror plate fitted into it is used.

However, in such wooden doors, especially when solid wood is used for the end panel, the end panel may expand and contract due to changes in temperature and humidity, causing distortions such as warping and twisting. There has been a problem that a gap is created between the frame and the frame due to the expansion and contraction of the frame, or even the frame becomes distorted such as warping or twisting.

Therefore, in order to solve this problem, the end plate is fitted into the frame with some play,
A device has been proposed in which the expansion and contraction of the end plate is absorbed by this play (see Japanese Utility Model Application No. 59-4158). However, with this proposal, not only is it not possible to prevent distortions such as warping and twisting of the head panel itself, but also the frame body may become distorted due to the distortion of the head panel. You can't expect any results.

(Purpose of the invention) In view of the above points, the purpose of the present invention is to improve the temperature and humidity of the wooden door by composing the head panel and frame of the wooden door with suitable composite materials without impairing the appearance. To provide a wooden door that can be used in a strong and stable state for a long period of time by effectively suppressing expansion and contraction deformation caused by changes.

(Structure of the invention) In order to achieve the above object, the invention has the following structure as a wooden door in which a mirror plate is fitted into a frame made of a stile and a muntin.

That is, the mirror plate is composed of a core material, a side member, and a decorative veneer, and the side member has a fitting edge that projects laterally from the decorative veneer, and the wood fibers are all in the same direction. The decorative veneer is bonded to the four peripheral end faces of the core material so that the decorative veneer is adhered from the surface of the core material to the surface of the side members. Further, the frame and the muntin of the frame are respectively constituted by a core material, a border material, and a decorative veneer, and each has a groove that can be fitted to the edge of the end plate, and the frame The end plate is fitted into the concave groove of the body with play.

In the above configuration, the end plate, frame, and muntin are all made of three members, and this three-member structure ensures a natural appearance while suppressing expansion and contraction deformation due to changes in temperature and humidity. ing. Furthermore, the play in the fitting structure of these members also absorbs expansion and contraction of the end plate.

(Effect of the invention) Therefore, according to the wooden door of the invention, the mirror panel, the stile, and the muntin are all composed of three members: the core material, the side member or the edge material, and the decorative veneer. ,
Since it is possible to effectively suppress the expansion and contraction deformation of these parts due to changes in temperature and humidity, this combined with the absorption of expansion and contraction due to play in the fit-in structure ensures that distortions such as warping and twisting of the mirror plate do not occur. It can be used in a robust and stable state for a long period of time. Moreover, since the wood fibers of the side members are all in the same direction, it is possible to obtain a natural appearance, and the production cost is lower than that of conventional panels and frames made of solid wood, making it economical. It is also advantageous in terms of implementation.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

FIGS. 1 and 2 show a wooden door body A according to an embodiment of the present invention, and this door body A is attached to the entrance of a building or the like via a hinge so that it can be opened and closed. The door body A has a frame 4 consisting of an upper stile 1, a lower stile 2, and vertical stile 3, and a vertical munt 5.
A frame body 7 is constituted by assembling the and horizontal kumiko 6 in a cross-shaped manner.
(10 pieces) of end plates 8,... are fitted into each.

The frames that are the constituent members of the framework 4 (upper frame 1, lower frame 2)
As shown in FIG. 3, the vertical stile 3) includes a core material 9 made of plywood, two edge materials 10, 10 bonded to both end surfaces of the core material 9 with adhesive, and the core material 9. It is constituted by two decorative veneers 11, 11 stuck from the 9 surface to the edges 10, 10 surfaces, respectively. The above edge material 10 and decorative veneer 1
1 is made of a material of the same tree species (for example, teak wood, etc.), and the inner edge material 10 of the two edge materials 10, 10 has grooves 12 formed by cutting along almost the entire length in the longitudinal direction. It has been formed over the years. Further, as shown in FIG. 4, the vertical and horizontal muntins 5 and 6 are composed of a core material 13, two edge materials 14, 14, and two decorative veneers 15, 15, similar to the frames 1 to 3 described above. Concave grooves 16 are formed at both left and right end portions of each edge member 14 over substantially the entire length in the longitudinal direction.

On the other hand, as shown in FIGS. 5 and 6, the end plate 8 includes a core material 17, four side members 18, 18,
... and two decorative veneers 19, 19, and the core material 17 is made of rectangular plywood. In addition, each core material 17 of the frames 1 to 3 and the muntins 5 and 6,
9 and 13 are also made of plywood like the core material 17 of the mirror plate 8. It is preferable to use plywood that has been adapted to the surrounding environment beforehand, as this will reduce the chance of warping later.

Further, the four side members 18, 18, ... are each bonded to the four peripheral end surfaces of the core material 17 with an adhesive so that their wood fiber directions (direction b in the figure) are all in the same direction. , the side members 18, 18 adjacent to each other are joined at the corners by a fastening structure, and the side members 18, 18, . . .
As a fitting edge that protrudes laterally from the decorative veneer 19 and can fit into the grooves 12 and 16 of the frame 7 (frames 1 to 3 and muntins 5 and 6), A convex portion 20 is formed over the entire circumference by cutting. Furthermore, the above two decorative veneers 19,1
9 from the surface of the core material 17 to the side members 18 and 1, respectively.
8, . . . is pasted over the surface to prevent the core material 17 from being exposed to the outside. The decorative veneer 19 and the side members 18 are made of the same tree material (for example, teak wood, etc.), and the wood fiber direction of the decorative veneer 19 (direction c in the figure) is the direction of the wood fibers of the side member 18 (direction b). ) are in the same direction.

However, when assembling door body A, frame 1
~3. After placing the muntins 5 and 6 and the head plate 8 in the predetermined positions, the convex portion 20 of the head plate 8 is fitted into the grooves 12 and 16 of the frames 1 to 3 and the muntins 5 and 6, and the frame is By joining 1 to 3 and the muntins 5 and 6 to each other using a dowel material (not shown) or the like, the door body A can be assembled with the head plate 8 fitted into the frame 7. ing. In addition, in the uneven fitting structure between the end plate 8, the frames 1 to 3, and the muntins 5 and 6, in order to mainly absorb the expansion and contraction of the end plate 8,
As shown in FIG. 2, the convex portion 20 of the end plate 8 is fitted into the grooves 12 and 16 of the frames 1 to 3 and the muntins 5 and 6 with play 21.

Therefore, in the above embodiment, the mirror panel 8 of the wooden door includes the core material 17, the side members 18, and the decorative veneer 19.
and the core material 17.
Since the stile 1 of the frame 7 is made of plywood, the expansion and contraction deformation of the mirror plate 8 due to changes in temperature and humidity can be significantly suppressed due to the antagonistic effects between each component and between each component of the plywood. ~ 3 and the muntins 5 and 6 are also constituted by a three-member structure of core materials 9 and 13, edge materials 10 and 14, and decorative veneers 11 and 15, and can prevent the frame 7 itself from becoming distorted. .

Moreover, the end plate 8, the frames 1 to 3, and the kumiko 5,
In the concave-convex fitting structure with 6, the convex portion 2 of the end plate 8
0 is the concave grooves 12 and 1 of the frames 1 to 3 and the muntins 5 and 6
6 with play 21, expansion and contraction of the end plate 8 can be absorbed. As a result, it is possible to reliably prevent the mirror plate 8 and the frame body 7 from becoming distorted, such as warping or twisting, and the wooden door can be used in a strong and stable state for a long period of time.

Moreover, since the wood fiber direction (b direction) of the side members 18 of the mirror panel 8 is all oriented in the same direction on all four sides, the edges (projections 20 ) can exhibit a natural appearance. In particular, when the decorative veneer 19 and the side member 18 are made of the same tree species as in the above embodiment, and the wood fiber directions of both 19 and 18 (c direction and b direction) are the same, the mirror plate It is possible to give a solid wood feel to the whole part of 8, and it is possible to obtain an even better appearance. Furthermore, since the edge materials 10, 14 of the frame 7 itself and the decorative veneers 11, 15 are made of the same wood species, the natural appearance of the wooden door as a whole can be further improved.

Further, in the case of the end plate 8 made of the three members described above, the production cost is lower than that of the conventional one made of solid wood, and it is advantageous in terms of economy. Furthermore, if the frame body 7 is also constructed from the above three members, it is more advantageous in terms of economy.

Note that the present invention is not limited to the above-mentioned embodiments, but includes various other modifications. For example, in the above embodiment, the end plate 8 is
In constructing the structure with three members, the side member 18 and the decorative veneer 19, plywood was used for the core material 17.
Laminated wood or the like may be used instead of plywood for the core material 17, and even in this case, the three-member structure of the end plate 8 can sufficiently suppress expansion and contraction deformation of the end plate 8 due to changes in temperature and humidity. can.
