DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door frame for receiving a door provided at an entrance of a building.

[0002]

2. Description of the Related Art A door frame for receiving a door provided at a doorway of a building is provided with a door stop, a packing made of a rubber-like elastic body, and the like on a door frame body mainly for maintaining the internal temperature and humidity and saving energy. When the door is closed, the closed door is brought into close contact with a door, a packing or the like without any gap, so that air does not enter from outside and air inside does not leak out. In some cases, a ventilating port such as a louver that can be opened and closed is provided on the wall or the door body in case ventilation is required.

[0003]

However, due to the above-mentioned hermetically sealed structure, in recent years, harmful organic solvents in building materials have volatilized, and many people have fallen into a condition called sick house syndrome by filling the room. There is a problem that harmful gas is generated from cooking utensils, heating appliances, smoking, and the like, thereby causing discomfort and causing toxic symptoms, thereby adversely affecting health. In order to prevent this, the door may be slightly opened and a piece of wood or the like may be fixed between the door frame and the door frame. However, it is unsightly and the door and the door frame may be damaged. There is. In addition, the ventilation port made of the louvers and the like described above is not only difficult to achieve a balance between the ventilation action and the design, such as a so-called “attached” feeling, and when it is necessary to install the ventilation port later, there are various cases. There is a problem that retrofitting is considerably difficult due to restrictions.

[0004] In addition, 1-6 due to omission / removal of a door stop
Formation of gap of about millimeter (opening area: 140-2
(40 square centimeters) is one simple measure that allows ventilation, but if the door stop is omitted or removed, light leaks from that part, making it unsightly and unsuitable especially for bedrooms and the like.

SUMMARY OF THE INVENTION An object of the present invention is to provide a door frame which has solved the above-mentioned drawbacks of the conventional door frame, has a simple structure, and is excellent in ventilation and light leakage prevention.

[0006]

In order to achieve the above object, a door frame according to the first aspect of the present invention removes at least a part of a door stop provided on a periphery of a door frame body (10), and removes the door stop. , The door frame body (1) of the closed door (20)
0) At a predetermined distance (S) from the side surface, the door (20)
And a light shielding body (T) that directly covers an end portion on the surface of the door frame body (10) side without contacting the door frame.

It is to be noted that a door frame in which all the door stops are removed and the above-mentioned light shielding body (T) is protruded therefrom, for example, a door frame which is supported only by a butterfly bank and does not come into contact with other parts is also included. .

According to a second aspect of the present invention, at least a part of a door stop provided on a peripheral edge of the door frame body is cut out, and the door is separated from the door frame body side surface of the closed door by a predetermined distance. A part of a light shield that directly covers an end portion of the door frame main body side surface without being in contact therewith is formed.

Further, in the invention according to claim 3, in addition to the structure according to claim 1 or 2, the predetermined distance (S) is 1 to 2
0 mm, and the width (W) of the end portion of the door frame body side surface of the door covered by the light shield (T) in the direction perpendicular to the direction along the door periphery is 5 to 20 mm. It is assumed that.

According to a fourth aspect of the present invention, in addition to the configuration of the first aspect, when the light shield (T) is closed, the door frame body (10) of the door (20) is closed when the door (20) is closed. ) It is free to move in a direction perpendicular to the side surface, and the distance (S) to the surface of the door (20) can be adjusted.

The symbols in parentheses indicate the corresponding elements or items in the embodiment of the invention shown in the drawings and described later.

According to the first or second aspect of the present invention, when the door is closed, an air passage is formed between the door, the door frame main body, and the door and the light shield in a part of the door frame main body. Since it is formed, air exchange between the inside and the outside is constantly performed. Moreover, since the light shield covers the end portion of the door frame body side surface of the closed door, light from the outside cannot pass through the inside or the inside light to the outside, so that light is not leaked. Absent.

[0013] Therefore, since the required ventilation volume is secured,
In recent years, harmful organic solvents in building materials have been volatilized, and sick house syndrome caused by volatilization and indoor filling, discomfort caused by generation of harmful gases from cooking utensils, heating appliances, smoking, etc., poisoning, etc. Since the adverse effect is eliminated and light does not leak, the present invention can be applied to a bedroom or the like. In addition, there is no need for a ventilation port consisting of a piece of wood or a louver to secure the door opened for ventilation, and a small, simple, light-shielding body that does not impair the appearance is provided, so it is not designed. Is almost completely eliminated. Also, if necessary, remove the existing door stop at any time,
Can be retrofitted.

In particular, according to the second aspect of the present invention, the light shield is not newly protruded at the portion where the door stop is removed as in the first aspect, but the door stop is notched, that is, the light shield is cut off. Since it is formed leaving a part, the number of parts can be reduced.

According to the third aspect of the invention, the operation and effect of the first or second aspect of the invention are maximized. That is, when the distance for forming the air passage is less than 1 mm, the opening area is small, and necessary and necessary ventilation is not performed. Further, if the distance exceeds 20 mm, light tends to leak, so that it is necessary to increase the width of the light shield covering the end portion of the surface of the closed door on the door frame main body side,
The following problems are derived. In terms of the light leakage prevention effect,
If the width of the light shield covering the end portion of the surface of the closed door is small, light leaks due to irregular reflection, so that the distance (S) is approximately 5 mm or more according to the size of the distance (S).
However, if the size exceeds 20 mm, the degree of freedom in design is significantly impaired, and the effective opening width of the door frame is reduced, which may hinder the passage of a wheelchair. .

According to the fourth aspect of the present invention, since the distance between the light shield and the door surface changes, and the opening area changes accordingly, the contact between the light shield and the door surface changes. Adjustment of ventilation volume and light shielding volume is possible, including stopping ventilation due to contact.

[0017]

Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing a part of a door frame according to the first embodiment of the present invention, and FIG. 2 is a cross-sectional view showing a part of the door frame according to the first embodiment of the present invention. It is.

In the door frame according to the first embodiment of the present invention, at least a part of a door stop provided on the peripheral edge of the door frame body 10 is removed, and the removed portion is provided with a closed door 20. A predetermined distance S from the surface of the door frame body 10 side
In addition, the light shielding body T that directly covers the end portion of the surface of the door frame main body 10 without touching the closed door 20 at all,
It is protruding and has the following details.

That is, as shown in FIG. 2, plate-shaped (I-shaped) light shields T are attached to the inner surfaces of the left and right sides of the door frame main body 10 via driving fittings U, respectively. The distance S between the light shield T and the surface of the closed door 20 is 1 to 20 mm, and the light shield T
The width W in the direction perpendicular to the direction along the door periphery of the end portion of the surface of the door 20 on the side of the door frame main body is set to 5 to 20 mm. Note that the light shield T is driven into the metal fitting U.
In place of the above, it may be attached with nails, wood screws, adhesive, adhesive, double-sided tape, or the like. In addition, a door stop is provided in a portion where the light shield T is not provided as in the related art except for the lower side (not shown).

According to the door frame having such a configuration, the door 2
0 is closed, the three sides (upper side,
At least a part of the left side and the right side) forms an air passage between the door 20 and the door frame main body 10 and between the door 20 and the light shielding body T, thereby constantly exchanging air between the inside and the outside. . Moreover, since the light shield T directly covers the end portion of the surface of the closed door 20 and light from the outside cannot pass through the inside or the inside light, the light does not leak.

Accordingly, 144 to 240 square centimeters can be obtained as an opening area determined by the distance S between the door 20 and the light shield T and the distance between the door frame body 10 and the door 20, so that a necessary ventilation volume is secured. In recent years, toxic organic solvents in building materials, which have become a problem in recent years, evaporate and fill the room with sick house syndrome.

Adverse health effects such as poisoning are eliminated. In addition, there is no need for a ventilation port made of a piece of wood or a louver for fixing the door 20 opened for ventilation, and a simple and narrow light shield T that does not impair the appearance is simply attached. There are almost no design restrictions. Also, if necessary, remove the existing door stop at any time,
Can be retrofitted.

According to the investigation results, when the distance S is less than 1 mm, the opening area is small, and necessary and necessary ventilation is not performed. If the distance S exceeds 20 millimeters, the width W covering the end of the surface of the closed door 20 will be described.
Needs to be increased, which leads to the problem described below. In terms of the light leakage prevention effect, if the width W of the light shield T covering the surface of the closed door 20 is small, light leaks due to irregular reflection, so that it is necessary to be 5 mm or more. It has been found that the degree of freedom in design is significantly impaired, and the effective opening width of the door frame 10 is reduced, which may hinder the passage of a wheelchair.

Further, the light shield T is not newly protruded from the portion from which the door stop is removed, and the door stop is set at a distance S.
Alternatively, when the door 20 is closed, the light shield T may be cut out in a direction perpendicular to the surface of the door 20 on the door frame body 10 side, that is, a part of the light shield T may be left. According to this, since it is not newly provided, the number of parts can be reduced.

Next, a second embodiment will be described with reference to FIG. 3. Light shielding bodies T each having an L-shaped cross section are attached to the inner surfaces of the left and right sides of the door frame body 10, respectively. The distance S between the body T and the surface of the closed door 20 and the width W covering the end portion of the surface of the closed door 20 are the same as those of the above-described first embodiment.

The third embodiment shown in FIG.
The configuration is the same as that described above, except that the light shield T is used in a letter shape.

In the third embodiment shown in FIG. 5, the light shield T is movable in a direction perpendicular to the surface of the door 20 on the side of the door frame body 10 when the door 20 is closed. The distance S can be adjusted.

More specifically, the door frame body 10
A light-shielding body T having an L-shaped cross-section is fitted in a guide G having a U-shaped cross-section attached thereto such that the light-shielding body T can be taken in and out. In addition, a fitting depth fixing mechanism F composed of a projection P and a recess H is provided on the opposing surfaces of the guide G and the light shield T so that the fitting depth can be fixed stepwise. Thereby, the distance S between the light shield T and the surface of the door 20 changes, and the opening area changes accordingly, so that the light shield T is brought into contact with the surface of the door 20. Adjustment of ventilation volume and light shielding volume is possible, including stopping ventilation.

The mounting portions of the light shield T in all the embodiments are not limited to the three sides of the door frame 10, and one or two sides of the door frame 10 do not have a possibility of tripping when passing. For example, all sides including the lower side may be used, and the cross-sectional shape may be various other than the above.
It is not limited to the above. In addition, the first and second
Except for the strength, any operation of this embodiment is substantially the same as that of the first embodiment, and need not be particularly described. That is, in terms of strength, the second embodiment is more L-shaped in cross section than the first embodiment, so that the mounting surface is more stable, and the third embodiment is more T-shaped than the first embodiment. And stable.

As described above, according to the first or second aspect of the present invention, since there is no problem of light leakage, the present invention can be applied to a bedroom or the like. The harmful organic solvent in the building materials is volatilized, and the sick house syndrome caused by filling the room, cooking utensils
Discomfort caused by generation of harmful gas from heating appliances, smoking, etc.
Adverse health effects such as poisoning are eliminated. In addition, there is no need for a ventilation port consisting of a piece of wood or a louver to secure the door opened for ventilation, and a small, simple, light-shielding body that does not impair the appearance can be attached, so the design Is almost completely eliminated. Also,
If necessary, the existing door stop can be removed and retrofitted at any time.

In particular, according to the second aspect of the present invention, the light shield is not newly protruded from the portion where the door stop is removed as in the first aspect, but the door stop is notched, that is, Since it is formed leaving a part, the number of parts can be reduced.
