Description

DETAILED DESCRIPTION OF THE INVENTION The present invention C↓, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, and 1 is concerned with an airtight 11 door used in the construction of air 11'.

Air membrane structure Q: A hemispherical structure with crossed wires.
By applying a membrane material to j11 and creating positive air pressure in the room, this membrane is given rigidity and supports the roof surface. With this air membrane structure, when the door is opened, the velocity of the sudden air flowing out from inside is extremely high at the moment the door is opened. For this reason, open-type doors are dangerous because they are easily blown open when opened.Of course, the door must be airtight to prevent all air pressure from leaking out of the room.

Conventional σ1] open-type doors are supported R11 so that they can rotate freely around one side of the door, and the gap between the door frame and the shaft constantly prevents internal forces and air from flowing out. It was dangerous because it was easily agitated when opened and closed. Also, even if a conventional door is opened by releasing the latch, it will return when the door is checked or the floor hinge is opened.
The current situation is that B[ does not return due to the atmospheric pressure in the room.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a door that reduces the amount of effort required to open and close the door, and has a high level of agility.

A feature of the present invention is that one end of an arm is connected to each of the two sides of the main shaft, and the other end of this arm is connected to a subshaft that is attached to the 1111 surface of the door. , Therefore, the door is constructed so that it can rotate around both the sub++i++ and the main shaft, and furthermore, the main II! Ill
is surrounded by a cover, the gap between the cover and the integral frame of the door is reduced, and an airtight elastic body is interposed in this gap.

When the countershaft is attached to the door unit, position τJ1ij (is located toward the main shaft side from the vertical center line of the door unit.) This is the point where the pressure exerted by the cam on the door unit is most likely to be dispersed. All should be selected.

The practical aspects of the present invention will be explained based on the drawings.

As shown in the first diagram, the door unit is attached to the main unit 2 via the hinge arm 3 and the sub unit 111+4 so that it can be closed. The Lord 11ζ112 is in Pnobar 5.6, 1 month, /! Therefore, the gap of 111'' between this cover and the door frame 1a is extremely small.
+IU has been completed. The -ψIM of the hinge arm 3 is rotatably connected to both the upper and lower ends of the main +14112, and the other end of this arm is rotatably attached to the side surface of the door unit 1; +lI4.

The outer end surface of the arm 3 should match the surface of the weight of the door as shown in the first figure.
A-so. In order to warp, the width of the arm 3 is made to match the depth of the storage m7, and the east Ij center of the sub-shaft is also made to match the surface of the door unit 1, and the tip of the arm is made into an arc with this axis as the entire center. The end of the groove 7 should also match this arc shape. The cover 5.6, which prevents the indoor air θ1 from being discharged from the storage m7 in this way, is made of steel and is made of steel.
It surrounds all the 119 forces of +2, f: A2
As shown in 1J, the top end is dissected (the top end is also the same)
There are pressed cutouts 5a and 6a for swinging the hinge arm 3.

And between the ends of the door frame 1a, there is an airtight elastic body 8 made of neoph L/N rubber (16 product names).
is implanted, and the cover is also implanted with an Ilt-based body 9. The door is made of tempered glass 1 by the door frame.
0 is being held.

Since the present invention maintains the above-mentioned IJM, the door unit 1 is connected to the main shaft 2. as shown by the chain line in FIG. Vice + i? h
When the door is opened centering on point 4, the pressure applied to the entire door is:
One is to act in the direction of opening this door as shown by arrow A, but at the same time pressure is applied as shown by arrow B, and the force at point B is exerted by the secondary shaft 4 as a lever. This acts as a force that pushes back the door itself. This reduces the amount of movement of the door itself.

Further Lord'! II 2 by cover 5.6; Tanachir
Because of this, the gap between the cover and the door is narrow, and since the airtight elastic body 8 is interposed therebetween, the airtightness is also excellent.
