Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a double soundproof door structure in which two swingable soundproof doors are arranged side by side at an appropriate interval in the direction of entry and exit.

In the conventional double soundproof door structure of this type, as shown in FIGS. 6 and 7, both soundproof doors +21, (
Each soundproof door was installed so that it could be opened and closed independently, but when using these, the two soundproof doors had to be opened and closed individually when entering and exiting, which was very inconvenient to operate. Moreover, due to this inconvenience, there is a drawback that it is easy to forget to close the door or leave the door ajar from time to time.

The present invention has an object to overcome such conventional drawbacks.

The characteristic configuration of the double soundproof door structure according to the present invention, which was taken to achieve the above object, is that a vibration isolating material is provided for interlocking the two soundproof doors so that the two soundproof doors swing open and close integrally in the same direction. The point is that it is

The operation of the present invention having such a characteristic configuration is as follows.

By interlocking both doors so that they swing open and close as one, both doors can be treated as essentially one door, and only one opening/closing operation is required for entering and exiting.

Moreover, since the component that makes all the doors interlock is a vibration isolator,
Even though both doors are interlocked, vibrations from one door are transmitted to the other door through the interlocking member, and there is very little deterioration in soundproofing performance due to this.

Therefore, the present invention has been able to provide a device that can be easily opened and closed while ensuring sufficient soundproofing performance.

Embodiments of the present invention will be described below based on the drawings.

Two soundproof panels (at) facing each other with a gap between them
, (am) A door structure for an entrance +Bl formed in a soundproof wall structure with a buffer material (a,) interposed between the two soundproof springs l (at).

(ax) entrance (door frame ill,
(1') and install these door frames +11
, (1') Each has a swinging soundproof door + 21,
(The two hinges are hinged in a stone state in which their swing axes (3), 31,
It is a double soundproof door structure installed through (8').

Both of the soundproof doors (21, (g') f:, both of the soundproof doors (21, (g') are opened in a swinging posture close to a right angle to the soundproof wall and in an overlapped state.
Of the two, the height and width of the soundproof door (2) located on one side in the entrance/exit traffic direction are configured to be larger than those of the other soundproof door (2/), and ) of the swing axis (the phantom is the swing axis of the other soundproof door (2) (X
The lever is also provided at a position displaced to the opposite side of the swinging free end of the door.

Then, a rubber vibration isolator (4) with a hardness of 30 to 70° is completely fixed to the other soundproof door (the two near the swing free ends), and the tip of this vibration isolator (4) is completely fixed. Then, the relay IV (member (6) which is attached to one of the soundproof doors (2) so as to be movable in the width direction) is fully fixed, and both soundproof doors +2 are fixed.
1. (The two doors are interlocked and connected so that they can swing open and close as one.

(7), (7') are both soundproof doors +21, (
In the second position, in the closed position, the door frame (1), (1/)
It is a soundproof airtight seal attached to the door using magnetic attraction force.
1. In (g'), the door frame +11 in the closed position,
(This is a soundproof airtight seal that is attached to the holder to make it fit elastically. +91, (9') is the handle.

According to the configuration of the above embodiment, both soundproof doors +
21. (Two can be opened and closed at the same time.

For this purpose, both soundproof doors +21, (the ninth part where the member that interlocks the g is vibration isolating material (4), both soundproof doors +21,
(2/), both soundproof doors (21, (2)
Since there is no vibration transmission between the doors, the function as a double soundproof door can be ensured, and in addition, since both soundproof doors (2) and (2) open so that they overlap each other, the equipment space can be reduced.
