Description

[Detailed explanation of the invention] This invention allows ventilation with peace of mind by using fixed louvers and insect screens provided on the upper and lower parts of the door body, so that when necessary, the door body can be completely locked with a lock, etc. ventilation,
In addition to facilitating daylighting and interaction with visitors, we also provide a
By sealing the opening with double sliding doors provided on the back side of the opening, it is possible to easily prevent the intrusion of wind, rain, noise, outside light, outside temperature, dust, etc. by any operation,
This invention mainly relates to a double-sliding, airtight, ventilation-adjustable door designed to be optimally used at the entrance and exit of a house, especially at the back door.

As a conventional door of this kind, for example,
As seen in Publication No. 050-1O57, a large number of ventilation holes are opened in the lower part of the surface plate of the door body, and insect repellent nets are placed on the back side of the holes. There were doors with so-called unrivaled ventilation windows, which were made up of a fixed plate with many ventilation holes and a sliding plate set against each other, but these only provided ventilation at a low position in the lower part of the door body. Because these doors were equipped with windows, if these doors were used as back doors, the heat, odors, smoke, and various harmful gases generated in the kitchen would not be exhausted at all through the ventilation windows. Not only does this significantly reduce ventilation efficiency, it is extremely unnatural and practically difficult to interact with visitors through the ventilation window, and since there is no fixed louver on the surface side, the aesthetics and aesthetics are affected. It had various drawbacks such as poor strength.

Other doors of this type have a lattice bar and a fixed louver fitted into the opening provided in the upper part of the door body, and transparent and opaque glass plates are installed on the front surface of the door, as disclosed in Japanese Utility Model Publication No. 13-13073. There was also a system in which the cylinders were arranged individually so that they could be raised and lowered, but in this case, the opening was only in the upper part, so it was completely impossible to discharge heavy gases such as propane, which tend to stagnate. In addition, this opening alone does not allow for circulation of internal and external air due to temperature differences and specific gravity differences, so highly efficient indoor ventilation cannot be expected.In addition, since there was no insect screen, insects and Not only can dirt easily enter the room, but even if an attempt is made to close the opening with each of the glass plates, no airtight material is interposed in the areas where the glass plates overlap, that is, in the mating areas. Because of its unreliable structure, it had various drawbacks such as easy penetration of not only drafts but also rainwater, dust, noise, outside temperature, etc.

Therefore, this device is a new device that eliminates the above-mentioned disadvantages, and has a substantially vertical opening in the upper and lower parts of the door body, and a large number of louvers from the surface side of the opening. A fixed looper consisting of left and right vertical frames and upper and lower horizontal frames installed in the horizontal direction is fitted, an insect screen is stretched on the back of the fixed looper, and upper and lower guide rails are attached to the back of the insect screen. In addition to being equipped with double sliding doors that open and close on the left and right,
An airtight member is interposed in the gap between both sliding doors and the fixed looper.

Therefore, if this door is made safe for crime prevention using various door locking devices, and both sliding doors are opened from the indoor side to the left and right, hot air etc. will be discharged from above the opening to the outside, and the door will be replaced. As fresh outside air flows into the room from below, indoor ventilation begins efficiently.

Moreover, during this ventilation, the fixed looper and insect screen fitted into the opening can simultaneously provide security, rainproof, daylighting, blindfolding, and insect repellent effects. Moreover, by equipping the openings in the upper and lower parts of the door body with double sliding doors that can be opened and closed from the left and right, at least several types of ventilation conditions can be achieved. In addition to being able to set or adjust the amount of ventilation as desired, when each sliding door is closed, the airtight members in each part prevent rain, gaps, dust, noise, outside light, etc. from entering the room. In addition, the large number of fixed loopers provided on the front surface provides a door with excellent aesthetics and strength that can be freely adjusted for airtightness and ventilation.

Next, one embodiment of this invention will be explained with reference to the drawings.
A door body 1 made of various materials such as metal and wood has substantially vertically elongated openings 2, 2 formed in the upper and lower parts of the door body 1.

A required number of fixed loopers 3, 3 are fixed and mounted in the horizontal direction on the front side of the openings 2, 2.

Next, an insect screen 4.4 is interposed on the back side of the fixed loopers 3, 3.

A pair of sliding doors 5, 5 which can be opened and closed by being pulled left and right are installed on the back sides of the insect screens 4, 4.

The fixed loopers 3, 3 are composed of left and right vertical frames 6, 6 and upper and lower horizontal frames 7.7.

Next, the outer peripheral edges of the insect screens 4, 4 are held by frame frames 8, 8, and the frame frames 8, 8 are attached to the vertical frames 6, 6 and the horizontal frames 7, 7.
It is fixed by fitting or screwing into a mounting part 12.12 provided in the.

Further, the sliding doors 5, 5 which can be pulled open left and right are provided with guide rails 9, 9 facing each other vertically.
9 are attached to the upper and lower edges of the openings 2, 2.

Further, in order to maintain airtightness when both sliding doors 5, 5 are in a closed state, longitudinal grooves 10 are provided in the vertical frames 6, 6, and various airtight members 11 are installed inside. A gap prevention protrusion (no reference numeral) is formed on the edge of one door frame at the joining part of the several-turn sliding doors 5,5.

Since this invention has the above-mentioned structure, even if the door is locked with a lock or the like, if ventilation or lighting is required, the sliding door 5.5 can be opened by pulling it to the left or right at any time. Since air and reflected light rays pass through the openings 2, 2 completely freely from the gap of the fixed looper 3.3, ventilation and light are freely allowed, but on the other hand, the insect screens 4, 4 prevent insects, dirt, etc. Intrusion into rooms will be reliably prevented.

In addition, each fixed looper 3, 3 is composed of a sloped part that goes down to the outdoor side and a vertical part that is connected to the sloped part, so rainwater naturally flows to the outdoor side when there is no strong wind. Since the fixed loopers 3, 3 are made of opaque material and have a blinding effect, it is also possible to prevent others from peeping into the room.

Furthermore, by forming the openings 2, 2 in a substantially vertical manner, especially in both the upper and lower parts of the door body 1, the circulation of internal and external air due to the difference in temperature and specific gravity of the gas is caused by the circulation of the inside and outside air through these openings. 2. As a result, the ventilation efficiency is significantly improved.

In addition, both sliding doors 5, 5 have upper and lower openings 2 of the door body 1.
, 2, so that on rainy days accompanied by strong winds, for example, in order to prevent wind from blowing in, both lower sliding doors 5, 5 are closed and the upper one is opened to allow ventilation. Alternatively, in order to avoid sudden changes in the room temperature in winter, it is possible to close both upper sliding doors 5, 5 and open the lower ones for ventilation. Since it can be opened and closed independently, there are several combinations of opening and closing, so there are various settings that can be adapted to the strength of the wind and rain, the temperature, the brightness and darkness of the room, the heat and smoke generated, etc. Moreover, it has the advantage of being able to do this reliably with an extremely simple operation, and as a result of making each sliding door 5, 5 smaller and lighter due to multiplication, the strength on the frame is increased. This prevents disadvantages such as damage and poor opening/closing...etc.

In addition, airtight members 11 and 11 are installed in the gaps between the vertical frames 6, 6 assembled on the fixed loopers 3, 3 and the sliding doors 5, 5.
In addition, at the joint part of the sliding door 5°5, there is a protrusion to prevent jamming (no code) on one edge of the door frame, so the sliding door makes noise due to vibration. This prevents rain, wind, dust, noise, outside light, outside temperature, etc. from entering the room.

In addition, the fixed looper 3.3 fitted into the approximately vertical opening has the effects of rainproofing, blindfolding, lighting, etc., as mentioned earlier, and also has the effect of crime prevention to prevent thieves from entering. At the same time, the strength of the frame completely prevents the opening from weakening and strengthens the door body.Furthermore, the fixed looper 3 has an appearance in which a large number of the fixed loopers 3 are arranged in an orderly row in the horizontal direction. It has a kind of functional beauty, and has an elegant decorative effect that completely changes the appearance of this type of door, which has traditionally been monotonous and undecorated.

Furthermore, the provision of substantially vertically elongated openings in the upper and lower parts of the door body not only improves the efficiency of ventilation by simply circulating inside and outside air, but also allows hot air to flow through the door. odor,
It has the effect of discharging light gases such as smoke and city gas (LNG), as well as heavy gases that tend to stagnate, such as propane. The material for the surface plate etc. cut out from the door body has sufficient dimensional space due to the interposition of vertical and horizontal frame rim materials (no code) that constitute the vertical stile 6, 6 and the outer periphery of both sliding doors. So,
This invention has manufacturing advantages such as being able to reuse it effectively as a constituent material for each picture sliding door...This invention has extremely practical effects.
