Description

Multi air tight device

The present invention relates to a multi-air tight door, and in particular, there is no failure, and an air tight insert (Air TightInsert: ATI) having a pair of flexible space barriers at the front and rear of the sound absorbing room is installed at the bottom of the door for sound insulation, insulation, and windproof. The present invention relates to a multi-air tight device having excellent performances such as dust, dust, deodorization, moisture proof, light shielding, smoke prevention, fire protection, and insect proofing.

Generally, steel doors installed at the entrances of buildings or apartments, and wooden doors installed between office rooms and corridors, and between home rooms and living rooms, are insulated from air tight structures for soundproofing, insulation, dustproofing, and windproofing. It is installed at the bottom.

Iron doors that are installed at the entrances of Woojin apartments and open only to the outside are provided with doorposts on the top and left and right sides of the door frame, but at the lower part, there is a certain gap between the door and the bottom surface for smooth opening and closing of the door. Although the specification of the building specification for this gap is specified to be about 3-5mm, the actual installed example has a gap of about 15mm, and sometimes more than that depending on the flatness of the floor.

Therefore, in most cases, the threshold is installed at the bottom of the door to limit the short-force position of the iron gate to block noise, dust, worms, heat loss through these gaps. In this case, the weather strip is installed in the door to achieve a sealing state in contact with the door jamb or the threshold while the door is closed, or the sound absorbing material for damping, soundproofing, and soundproofing is attached to the doorpost or the threshold.

However, the door structure installed with such a threshold forms obstacles or causes inconvenience for pedestrians, disabled cars, and vacuum cleaners to pass, and air tight doors without a threshold have been proposed. The same happens if.

The conventional air type door without a threshold has been proposed in which a fixed single sealing brush is attached to the bottom of the door, but it is not easy to replace when the brush is worn, and the sealing effect is greatly reduced with time. (See Utility Model Notification No. 192-8921)

One proposal for solving such a brush wear problem is disclosed in Utility Model Publication No. 90-9853. This proposal is installed in the inner lower end of the door and the brush is lifted from the floor by the elastic force when the door is opened, and when the door is closed, the brush is lowered to start the "door windbreaker" using the elastic force to contact the bottom surface. Doing.

However, since the windbreak device is installed outside the door, the exterior beauty of the door falls, and a single brush is used to reduce the sealing effect, and when the door is frequently opened and closed, the support supporting the brush may be broken and failure may occur.

On the other hand, a magnetic air tight door system that improves the appearance problem described above is shown in Figures 1a and 1b. The door system is provided with a bottom rail (1) having a groove of Al material which is not influenced by a magnet is installed on the bottom surface (9) of the door, and movable movable permanent magnet (up and down) in the groove of the rail (1) 3) is inserted, a fixed permanent magnet 7 is installed at the lower end of the door (5). Therefore, when the door 5 is open as shown in FIG. 1A, the movable permanent magnet 3 is separated to descend to the groove of the rail 1, and when the door 5 is closed as shown in FIG. 1B. The movable permanent magnet 3 is adsorbed by the fixed permanent magnet 7 to exhibit a sealing function.

However, such a magnetic door system has a foreign material, such as soil, sand, or dust, stuck in the gap between the floor rail (1) and the movable permanent magnet (3), or a foreign material magnetic body is attached to the fixed permanent magnet (7). If there is an inoperable or malfunctioning state, there is a problem in that the cleaning to remove the foreign material frequently. Moreover, whenever the movable permanent magnet 3 is adsorbed to the fixed permanent magnet 7, adsorption noise is generated, and the adsorption force of the permanent magnet 7 degrades the smoothness when the door is opened.

On the other hand, in order to realize the air tight door, not only the space blocking on the lower end of the door but also the space blocking on the side of the door is required. For this purpose, in the prior art, a weather strip made of a mohair or neoprene was inserted into a groove of a specific portion to implement this, but such a structure is, for example, inadequate for use in a glass glass door, and furthermore, there is a problem in that it is inadequate in flexibility for application to various doors.

Therefore, the present invention has been made in view of the problems of the prior art, the object of which is that there is no failure and the air tight insert having at least one pair of flexible space barriers in the front and rear of the sound-absorbing room installed on the lower end of the door, sound insulation, heat insulation To provide a multi-air tight device with excellent performances such as windproof, dustproof, deodorant, moistureproof, shading, flame retardant, fireproof and insect repellent.

Another object of the present invention is to provide a slide-opening window having the above air tight insert.

It is a further object of the present invention to provide a door having a multi-air tight strip for air tighting the side of the door simultaneously or independently with the airtight insert at the bottom and top of the door.
