Description

  The present invention relates to a soundproof door with a finger clogging prevention function.

  Conventionally, there has been no rotary door type soundproof door having a finger clogging prevention function, that is, an accident prevention function that clogs a finger in a gap between the door butt when the door is closed. Although there has been an instrument that rotates the cover that hides the gap between the door butt, it has not been soundproof, and because it is exposed to the outside, it is prone to failure and is not preferable in terms of design.

The method of eliminating the gap through which sound is transmitted and the method of not pinching the fingers contradict each other, making it difficult to achieve both. In addition, there are devices that allow the cover to enter and exit so that fingers do not enter, but because they are exposed, they are not excellent in design and are prone to failure.
Patent Document 1 discloses a technique in which a concave portion is provided on a door contact side of a door panel as a finger plugging prevention mechanism.

JP 2000-145275 A

  However, the technology of Patent Document 1 is a configuration in which a recess is provided in a part of the door panel except for the hinge portion, but it is not a soundproof door. Since it becomes different by the recessed part which has a clogging prevention function, a mechanism will become complicated. As can be seen from this example, the finger clogging prevention mechanism itself is a technology in the direction of providing a gap in the vicinity of the rotation fulcrum of the door, whereas the soundproofing mechanism is a technology that finally closes the gap in the vicinity of the fulcrum. However, it was difficult to realize a mechanism that shared the functions of both.

  This invention solves the said subject, and makes it a subject to provide the rotary soundproof door which implement | achieves the soundproofing of a door bottom part with a compact mechanism while having a finger-clogging prevention function.

In order to solve the above-mentioned problems, the invention of claim 1 is directed to solving the above-mentioned problems. The invention of claim 1 is a rotary type soundproof door, and a protrusion is arranged on a door bottom having a rotation fulcrum. In the horizontal section of the door butt, a predetermined gap is maintained between the door butt and the door butt during operation from the time the door is opened to when it is closed, and the soundproof mechanism provided in the door butt is covered over the entire length. A cover arranged in a mode, and first and second insulators arranged in a fixing part outside the door located inside the cover, one end abutting against the protrusion when the door is closed, and the other end A first insulator that contacts one end of the second insulator, and a second insulator that is disposed at the other end of the second insulator, the AT rubber contacts the gap between the door bottom portion and the fixed frame portion. It is characterized by having a thing which interrupts the passage of sound.
The invention of claim 2 is further characterized in that the other end of the first insulator is connected to a fixed frame portion outside the door by a spring.

  According to the present invention, there is provided a rotary soundproof door that has a finger clogging prevention function and realizes soundproofing of the door butt portion with a compact mechanism.

It is a figure which shows the soundproof door with a finger-clogging prevention function of this embodiment, (a) is a front view, (b) is a front view, (c) is a side view. It is a horizontal sectional view of the door bottom part of this embodiment.

Embodiments of the present invention will be described below with reference to the drawings.
First, the configuration of the present embodiment will be described.
As shown in FIGS. 1 and 2, the soundproof door with a finger-clogging prevention function of the present embodiment is a rotary type soundproof door 1, and a protrusion 4 a is provided on a door bottom 3 a having a rotation fulcrum 1 a. In the horizontal cross section of the door butt portion 3a, the following soundproofing mechanism arranged on the door butt portion 3a is maintained in the vertical and full length while maintaining a predetermined gap 7a with the door butt portion 3a during the operation from the opening to the closing of the door 1. A cover 8 disposed in a covering manner, and a first lever 5a and a second lever 6a disposed in a fixing portion 2 outside the door 1 located inside the cover 8, wherein the door 1 is closed. Sometimes the one end 5b is in contact with the projection 4a, and the other end 5c is in contact with the one end 6b of the second insulator 6a, and the second insulator 6a is in contact with the other end 6c when the door 1 is closed. The disposed AT rubber 6d comes into contact with the gap 7b between the door bottom 3a and the fixed frame 2 to block the sound passage. The other end 5c of the first insulator 5a is connected to the fixed frame portion 2 outside the door 1 by a spring 5d.

  Moreover, the soundproof door 1 of this embodiment has the front-end | tip part sealing material 4b as a soundproof mechanism from the upper part of the front-end | tip part of the door 1 to the lower part. Furthermore, it has the upper sealing material 4c as a sound-proofing mechanism from the front-end | tip part of the door 1 to a door butt part, and it is the same by the sealing material not shown also from the front-end | tip part of the lower part of the door 1 to the door butt part. It has a soundproofing mechanism.

The AT rubber is air tight used for door wind countermeasures and sound countermeasures, that is, rubber having an airtight function.
The AT rubber 6d is disposed over the entire length of the door bottom 3a in order to close the gap 7b. However, the protrusion 4a, the first lever 5a, and the second lever 6a are respectively connected to the door bottom 3a. As long as it is arranged at a plurality of locations so that the adhesion force to the gap 7b of the AT rubber 6d is properly and evenly applied within the full length of the top and bottom of the door butt portion 3a. Good.

The function of the soundproof door with the finger clogging prevention function of this embodiment will be described.
When the door is closed while maintaining a structure in which the finger does not enter the door bottom, the projection on the door rotates the AT rubber by the lever principle and closes the gap, thereby closing the path of sound transmission.
Specifically, the cover 8 realizes a structure in which a finger does not enter the vicinity of the door bottom 3a. That is, as shown in FIG. 2, the cover 8 covers all of the soundproofing mechanism when the door 1 is closed, and maintains a gap 7a having a dimension less than a predetermined finger width at the boundary Q with the door bottom 3a. It is comprised in the aspect. In this way, the cover 8 largely covers the gap 7b that realizes the soundproof seal so that fingers do not enter, and the end of the cover 8 is a boundary portion Q and a substantially constant distance from the door bottom 3a that is a movable part. It is possible to provide a rotary soundproof door that has both a soundproofing function and a function to prevent finger clogging by realizing a compact soundproofing function in the cover 8 by using the insulators 5a and 6a and the AT rubber seal 6d. It is said.

The operation when the soundproof door 1 is closed will be described with reference to FIG.
When the door 1 is closed from the state in which the door 1 is opened at 90 °, the protrusion 4a of the door bottom 3a moves from P to Q. As a result, the first insulator 5a rotates counterclockwise, and the second insulator 6a rotates counterclockwise. As a result, the AT rubber 6d attached to the other end 6c of the second insulator 6a contacts and closes the gap 7b between the door bottom 3a and the fixed frame 2 to close the gap 7b through which sound passes.

The effect of this embodiment is demonstrated below.
The rotating part is inside the cover, there is no possibility of accidents such as finger jamming at this part, and the soundproofing mechanism does not break down due to external factors. The design is neat and the operation for soundproofing is automatic and simple. That is, the sound-insulating performance is exhibited by closing the gap where the AT rubber is in close contact with the door bottom and the fixed frame by the interlocking mechanism of the two levers that are in contact with the protrusion of the door bottom.
