Abstract

PURPOSE: To carry out ventilation even in the condition where a door is closed, without losing the design quality of a door section, by providing the upper surface of a door head with a recess or a vent hole having sectional width larger than the thickness of a wall body. CONSTITUTION: An open section 1 formed between a wall body 2 and a floor 3 to divide a building habitable room is provided with a door frame 4, and a door 5 is rotatably mounted on the frame 4 via a hinge or the like. The door head 4a of the frame 4 is fixed to the upper end section 2a of the section 1 in close contact therewith. Also, a recess 6 or a vent hole communicated to the inner and outer sides of the door 5 is formed on the upper surface of the head 4a. and the sectional width thereof is made sufficiently larger than the thickness of a wall body 2 for keeping a gap 6a. According to this construction, a passage for ventilation is formed between rooms, structures or the like at both sides of the wall body 2.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door part ventilation structure for ventilating a door part provided at a doorway.

[0002]

2. Description of the Related Art Conventionally, in order to ventilate the inside and outside of a door from a door provided in an opening of a wall of a building, it is common to open the door halfway or fully, but in recent years, crime prevention Various types of door structures have been devised, which take into account the privacy, privacy, and sound insulation effects, and which ventilate when the door is closed.

For example, a ventilation sound-insulating plate described in Japanese Utility Model Laid-Open No. 57-16517 or a sound absorbing material is filled in an opening provided in a part of a particle board of Japanese Utility Model Laid-Open No. 62-155194, and the front and back surfaces are filled with the sound absorbing material. Like a soundproof door with a vent, which is made by sticking a decorative material and opening a vent opening smaller than the above opening, and installing a cover, the door has an opening, and the vent has sound absorption in this opening. A ventilation structure of a door is described in consideration of sound insulation or sound insulation provided with a material or sound insulation material.

[0004]

However, the above-mentioned Japanese Utility Model Publication No. 57-16517 and Japanese Utility Model Publication No. 62-1551.
If the door is provided with a vent hole as described in Japanese Patent Publication No. 94, the exterior design of the door itself is poor, and the air passing through the vent hole directly hits the human body, resulting in poor ventilation. There is such a problem. Further, if a door provided with a sound insulation function in addition to ventilation is required, a special order is made and a separate order is made. Therefore, the original door cannot be used, which is uneconomical.

The present invention has been made by paying attention to such conventional problems, and the purpose thereof is to solve these problems and to provide necessary ventilation.
Provided is a door ventilation structure that does not impair the appearance and design of the door.

[0006]

According to the door part ventilation structure of the present invention, there is provided a door part ventilation structure in which a door frame and a door are attached to an opening of a wall of a building. It is characterized in that a concave portion or a through hole communicating with the inside and outside of the door is provided on the upper surface of the door upper frame which is in contact therewith.

When the thickness of the door upper frame is, for example, 30 mm, the depth of the concave portion on the upper surface of the door upper frame is 5 mm to 15 mm.
Is preferred. Further, in addition to piercing a wood-based material to provide the recess, in a door frame or the like using a plastic material, the recess may be formed at the same time as the molding process.

[0008]

In the door part ventilation structure of the present invention, since the upper surface of the door upper frame that abuts the end face of the wall is provided with the recess communicating with the inside and outside of the door, it is difficult to see the appearance and the door part is designed. Ventilation can be done with the door closed without damage,
Also, since the ventilation passes through the recess above the door, or the through hole,
The human body is not directly exposed to the wind and does not impair the experience. Further, even when sound insulation performance is desired, there is an advantage that a common door for sound insulation can be used.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a sectional view showing an example of a door part ventilation structure of the present invention. In FIG. 1, a wall body 2 that partitions the living room of the building
A door frame 4 is provided in the opening 1 provided between the door frame 4 and the floor surface 3, and the door 5 is rotatably attached to the door frame 4 by a hinge or the like.

Reference numerals 4a and 4b denote an upper door frame and a lower door frame of the door frame 4, and the upper door frame 4a is fixed by abutting against an upper edge 2a of the opening 1 of the wall body 2. This door upper frame 4a
A recess 6 is formed on the upper surface of the. In consideration of the design, the recess 6 is not provided in the width direction of the door upper frame 4a as shown in FIG. 1, but is left at both ends. or,
In order to ensure air permeability, the width of the concave portion 6 in the cross-sectional direction is made sufficiently wider than the thickness of the wall body 2 so that the gap 6a can be secured.

Therefore, between the upper edge 2a of the opening 1 of the wall body 2 and the upper door frame 4a, a gap is formed which communicates with the living room on both sides or the outside with the wall body 2 as a boundary. A passage is formed.

FIG. 2 is a perspective view showing an example of a recess provided in the upper frame of the door of FIG. In FIG. 2, 6, 6, ...
Shows a concave portion formed in the upper surface of the door upper frame 4a, and shows an example provided by being divided into a plurality of parts in the longitudinal direction of the door upper frame 4a. Further, in order to allow the air that has entered through the gap 6a shown in FIG. 1 to smoothly pass through the concave portion 6, the corner portions 6b on both sides of the concave portion 6 have smooth curved surfaces.

In the present embodiment, the concave portion 6 is divided into a plurality of portions, but the present invention is not limited to this and may be continuous. Also, in consideration of the appearance and design, the concave portion 6 is formed in a state where the end is left so as not to be seen from the outside, but it is not particularly limited to this, and the design is taken into consideration. It may be a concave portion which is processed by design and the end portion is removed.

FIG. 3 is a cross-sectional view showing another example of the door upper frame of the door ventilation structure of the present invention, in which the sheet-shaped sound absorbing material 20 is attached to the recess 11 provided in the door upper frame 10. FIG. By adhering this sound absorbing material 20, it is possible to expect an effect of absorbing a human voice, noise, or the like that enters through the gap and suppressing a decrease in sound insulation performance.

A sheet-shaped sound absorbing material 2 provided in the recess 11
0 is preferably a fiber type, a foamed resin type, or a ceramic type.

FIG. 4 is a cross-sectional view showing still another example of the door upper frame of the door part ventilation structure of the present invention. The door upper frame 30 has a through hole which opens on the upper surface thereof and communicates the inside and outside of the door. 31 is provided.

[0017]

In the door ventilation structure of the present invention, since the upper surface of the door upper frame that abuts the end face of the wall is provided with a recess or a through hole that communicates with the inside and outside of the door, it is difficult to see in appearance. Ventilation can be performed with the door closed without impairing the design of the door, and since the ventilation passes through the concave portion above the door, the human body is not directly exposed to the wind and does not impair the feeling. Further, even when sound insulation performance is desired, there is an advantage that a common door for sound insulation can be used. Therefore, it is suitable as a door ventilation structure.
