Description

[Detailed Description of the Invention] This invention relates to a door airtight device for maintaining good airtightness between the door and the door frame.

Doors are generally constructed as one example is schematically shown in FIG. 1 (cross-sectional view). That is, the door frame 2 is attached to the edge of the opening provided in the wall 1, the right stile 3a of the door 3 is pivoted to the right frame 2a of the door frame with a hinge 4, and the left stile 3b of the door is attached to the left frame 2.
The door can be closed by hitting the protrusion 2c of b, or opened in the direction of the arrow. In order to connect the door 3 and the door frame 2 airtightly, a packing is inserted between them.

The purpose of this invention is to obtain an airtight device for a door that can maintain good airtightness by adjusting the packing position even if there are manufacturing or assembly errors on the three sides of the door excluding the bottom. .

This invention will be explained below using as an example FIG. 2 (a cross-sectional view) showing the relationship between the left frame 2b of the door frame and the left stile 3b of the door. Components equivalent to those in FIG. 1 are given the same reference numerals.

The protrusion 2c of the left frame 2b of the door frame 2 projects into the opening from the left frame 2b in a hook shape, and a hollow square rod-shaped rubber packing 5 is fitted into the protrusion 2c, so that one side surface 5a of the packing protrudes slightly. Left stile 3b of door 3
collide with.

The side surface inside the opening of the left frame 2b has an inclined surface 2d on the side where the door opens. This left frame 2b is made of aluminum shapes, and has iron anchors 6 at several places inside.
It is attached to the steel frame 7 that constitutes the wall 1 by screws or welding.

The left stile 3b of the door 3 is made of an aluminum profile with a horizontal H-shaped cross section closed by recessing the right end, and a panel 9 is fitted to the recessed right end via a padding with a ribbed edge 8.

A metal fitting 10 with an inverted U-shaped cross section is fitted into the open left end of the left stile 3b, and a screw 12 is inserted through the horizontal long hole 11 as shown in FIG. It is screwed onto the side of the metal fitting 10. The metal fitting 10 is covered with a flexible packing 13 made of rubber or the like having a generally U-shaped cross section as shown in FIG.
Screw 16 passed through the loose holes 14 and 15 provided in e.
is screwed into a nut 18 welded to a metal fitting 17 fitted to the left frame 3b.

Since the structure is as described above, the screws 12, 12
is tightened to fix the metal fitting 10 inside the left stile 3b, and then the screw 16 is tightened, the packing 13 is fixed to the metal fitting 1.
It is pressed to 0 and fixed. When the door 3 is closed in this state, both the first and second lips 13a and 13b of the packing 13 contact the inclined surface 2d of the left frame to maintain airtightness, and the side surface 13c of the packing contacts the packing 5 to close the door. It cushions the impact when closed and maintains airtightness afterwards. A cavity 13d into which the end of the left stile 3b of the door is inserted is formed inside the side surface 13c of the packing.

If the angle of the sloped surface 2d of the left frame becomes larger than the normal value due to manufacturing errors in the mold material or errors in mounting it to the opening, the contact of the first lip 13a will become weaker and the lip will separate again, making it impossible to maintain airtightness. If this happens, loosen the screw 16, move the screw 12 to the left in the long hole 11, tighten it, and then tighten the screw 16 again. It can be moved to the left with respect to the stile 3b, and the contact between the first lip 13a and the inclined surface 2d can be made appropriate.
Similarly, depending on the condition of the inclined surface 2d, the packing 13 can be pushed into the left stile. These movements of packing 13 are such that the left stile 3b of the door is empty space 1.
It is inserted with a margin within 3d, so it can be done freely.

In the above embodiment, the structure of the left frame of the door frame and the left stile of the door was described, but the right stile and the upper stile of the door can also be constructed in the same way to adjust airtightness. . Since the screw 16 cannot be operated between the door and the floor, separate consideration must be given to keeping this area airtight. Of course, the same structure can be applied to cases where the door opening is provided higher than the floor or to a revolving window that has the same structure as the door.

As described above, the airtight device of this invention has a lip 1.
The packing 13 with the lips 13a, 13b and the gap 13d formed as described above is connected to the metal fitting 10 which can move along the side portions 3c, 3d of the door frame. Therefore, even if there is an error in the manufacturing or installation of the door, the lips 13a,
The lip 13b can be easily adjusted so that it abuts well against the inclined surface 2d of the door frame 2, maintaining airtightness. During this adjustment, the outer side surface 3d of the door frame is inserted into the space 13d formed in the packing 13, so that the abutment of the side surface 13c of the packing against the side surface 5a of the packing 5 and the abutment of the lip 13b against the inclined surface 2d of the door frame can always be kept good regardless of this adjustment, and this has a great practical effect as an airtight door device.
