Description

[Detailed description of the invention] (Industrial application field) The present invention relates to doors, particularly those made of wood.

(Prior art) In recent years, due to the spread of air conditioning equipment, the temperature and humidity differences between the inside and outside of a room partitioned by a door have become large.
This causes the door to warp, creating gaps and causing inconveniences such as the door getting caught when opening and closing.

Therefore, in an attempt to eliminate such inconveniences, a door such as that described in, for example, Japanese Utility Model Publication No. 2-20399 has been devised.

The core material of this conventional door is a frame material consisting of an upper stile, a lower stile, and a pair of vertical stiles, and a horizontal rail is provided on the frame material, and all these members (upper stile,
Ventilation holes are formed in the lower stile, vertical stile, and horizontal stile. That is,
In the conventional door, ventilation is performed between the inside and outside of the door, which alleviates the temperature and humidity differences between the inside and outside of the room partitioned by the door, and prevents the door from warping.

(Problem to be solved by the invention) However, in such conventional doors, the ventilation holes provided in the vertical stile of the core material appear on the side of the door.
It is visible when the door is opened, closed and opened, spoiling the beauty of the door. In addition, although attempts have been made to increase the ventilation effect by providing ventilation holes in the horizontal beams, it takes time and effort to process, and
There was a problem in that the strength of the horizontal beam as a reinforcing material was reduced.

The present invention was made in view of the above-mentioned problems, and an object of the present invention is to provide a door that can prevent warping without impairing its aesthetic appearance.

(Means for Solving the Problems) In order to solve the above problems, the door of the present invention has a core material in which a middle crosspiece is provided in a frame material formed by an upper stile, a lower stile, and a pair of vertical stiles. , in a door configured with a pair of face materials provided on both sides of the core material, a middle crosspiece of the core material is provided vertically, and a ventilation portion is formed in the upper stile and the lower stile, The core material is provided with a wooden brick.

(Function) In the door of the present invention, the middle frame of the core material is provided vertically, and ventilation portions are formed in the vertical stile and the upper and lower stile of the frame material. An air flow path is formed in the vertical direction to provide ventilation between the inside and outside of the door. Therefore, the difference in temperature and humidity between the inside and outside of the room partitioned by the door is alleviated, so that the door does not warp.

In addition, the ventilation part formed in the upper stile appears on the upper end surface of the door, and the ventilation part formed in the lower stile appears on the lower end surface of the door, so when the door is opened, closed, or opened, Inconspicuous.

Further, since the door of the present invention has a wooden brick as the core material, it is reinforced in the torsional direction.

(Example) The present invention will be explained in detail below.

First, the configuration will be explained based on FIGS. 1 and 2.

Fig. 1 is a perspective view showing the core material A of the door according to the embodiment of the present invention;
The figure is a front view of the core material A. This core material A has a rectangular frame material 10 formed by an upper stile 1, a lower stile 2, and vertical stile 3a, 3b. Crosspieces 4a, 4b, and 4c are provided vertically.

Further, the upper stile 1 and the lower stile 2 of the frame material 10 each have four grooves 1a, lb, 1c, l as ventilation parts.
d and grooves 2a, 2b, 2c, and 2d are formed. The grooves 1a, lb, 1c, ld are alternately formed on both sides of the upper frame 1, and the grooves 2a, 2b,
2c and 2d are formed alternately on both sides of the lower stile 2. Furthermore, the grooves 1a, 1b, Ic, 1d and the grooves 2a, 2
b, 2c, and 2d are provided at positions that communicate the portions between the middle bars 4a, 4b, and 4c and between the middle bars 4a, 4b, and 4c, and the vertical frames 3a and 3b, respectively, with the outside.

Furthermore, wooden bricks 6 are pasted on the inner surfaces of the vertical frames 3a, 3b and on both sides of the middle crosspiece 4b.

The wooden bricks 6 are provided at three locations on each of the vertical frames 3a and 3b, and are provided at three locations on the top and bottom of the middle frame 4b.

FIG. 3 is a cross-sectional view showing the door of this embodiment, and this door is constructed by pasting face materials 7a and 7b with decorative surfaces on both sides of the core material A.

That is, the inside of this door has the middle crosspieces 4a and 4b.

4c creates four spaces 5a, 5b, 5c,
5d, each space 5a, 5b, 5c,
In the sct, an air flow path is formed in the vertical direction of the door by grooves 1a, 1b, lc, and ld of the upper stile 1 and grooves 2a, 2b, 2c, and 2d of the lower stile 2.

Next, the operation of this embodiment will be explained.

As explained above, in the door of this embodiment, air flow paths are formed in the four internal spaces 5a, 5b, 5c, and 5d. Ventilation is provided between the inside and outside of the door. In other words, the difference in temperature and humidity between the inside and outside of a room partitioned by a door is alleviated.
The door will no longer warp.

Further, grooves 1a and lb formed in the upper frame 1.

Ic and 1d appear on the upper end surface of the door, and grooves 2a, 2b, 2c, and 2d formed in the lower stile 2 appear on the lower end surface of the door, so they are both noticeable when the door is opened and closed. do not have.

In other words, in the door of this embodiment, the groove 1 as the ventilation section
Although a, lb, lc, ld, 2a, 2b, 2c, and 2d are formed in positions that are difficult to see when the door is opened, closed, or opened, ventilation is performed between the inside and outside of the door. This prevents the door from warping without compromising its aesthetic appearance.

Further, since the door of this embodiment is provided with the wooden brick 6, twisting can be prevented.

Although the embodiment has been described above based on the drawings, the specific configuration is not limited to this embodiment, and even if there is a design change within the scope of the gist of the present invention, it is included in the present invention. .

For example, in the embodiment, grooves were formed as ventilation portions in the upper and lower stile of the frame material, but holes may be formed instead of grooves. Further, the shapes of the grooves and holes may be any shape such as circular or rectangular.

(Effects of the Invention) As explained above, in the door of the present invention, the middle crosspiece of the core material is provided vertically, and the ventilation portions are formed in the upper and lower stiles of the frame material. Even though the part is formed in a position that is difficult to see when the door is opened, closed, or opened, it allows ventilation between the inside and outside of the door, thereby preventing the door from warping without impairing its aesthetic appearance. You can get the effect that you can.

Furthermore, since the door of this embodiment is provided with wooden bricks, twisting can be prevented.
