Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The soundproof door apparatus according to the present invention is installed at a doorway where it is necessary to sufficiently provide internal and external sound insulation in a closed state, such as a doorway of a broadcasting studio or a recording studio.

[0002]

2. Description of the Related Art Soundproof door devices must be provided at the entrances of broadcasting studios and recording studios to prevent external sounds from entering the studio and to prevent internal sounds from leaking out. is there. For this purpose, various types of soundproof door devices have been proposed and actually used. Among those soundproof door devices that have been conventionally known, those having sound insulation performance that can be used at entrances and exits of broadcast studios and recording studios, the door panel moved to the closed state is opened by the handle. The frame is pressed against a packing mounted on a part of the front surface (the front surface in the moving direction when the door panel moves in the releasing direction, the same in the entire specification).

That is, in a state where the inside of the opening frame is closed by the door panel, a handle attached to the door panel is operated, and the door panel is further pressed toward the closing side by a fastening mechanism built in the door panel. The four peripheral edges of the rear surface of the door panel (the rear surface in the moving direction when the door panel moves in the releasing direction, the same in the entire specification) are pressed against the packing. The reason why the fastening mechanism is incorporated is that the packing incorporated in the conventional soundproof door device has high rigidity and a large repulsive force. That is, only the force of the closer (a device that elastically urges the door panel in the closing direction) provided between the door panel and the opening frame ensures that the rear surface of the door and the packing are secured over the entire circumference. Therefore, the four peripheral edges of the rear surface of the door panel are pressed against the packing by the fastening mechanism.

[0004]

In the case of a soundproof door device incorporating a fastening mechanism, a handle for operating the fastening mechanism must be operated each time the door is opened and closed, which is troublesome. In particular, it is difficult to release the door panel while holding an object in hand, which is a cause for having to enter and exit a broadcast studio or a recording studio. The present invention
In view of such circumstances, the present invention was invented in order to realize a soundproof door device capable of exhibiting sufficient sound insulation performance without increasing the force particularly required to press the door panel toward the packing.

[0005]

The soundproof door device of the present invention comprises:
Like a conventionally known soundproof door device, a rectangular opening frame formed by combining an upper frame, a lower frame, and left and right vertical frames,
At least two horizontal edges on either side of the vertical frame
At least one door panel slidably displaced inside the opening frame by being connected by the hinge members, and the four peripheral edges of the door panel are opposed to the four peripheral edges when closed. And a packing for closing a gap between the four peripheral edges and the mating member.

[0006] In particular, in the soundproof door device of the present invention, the first packing for closing the gap between the mating member and three edges of the four peripheral edges of the door panel except for the lower edge. Is
A part of the mating member is locked to a front portion facing the three edges, and is crushed by a light force by the back surfaces of the three edges when the door panel is closed.
A fin-shaped portion having elasticity in a direction for displacing a leading edge toward the back side of the door panel is provided. At the lower ends of the left and right vertical sides of the door panel, airtight blocks made of a soft material are provided so as to be continuous from the first packing. Then, with the fins of the first packing crushed with the closing of the door panel, the front surface of the first packing and the front surface of the airtight block are located on the same plane. is there.

On the other hand, the second packing for closing the gap between the lower edge of the four peripheral edges of the door panel and the upper surface of the lower frame as the mating member is made of an elastic material. The lower part is locked to the lower edge of the door panel over the entire length of the lower edge, and extends downward from the lower edge of the door panel, and the first packing extends from the lower edge of the lower part. And an inclined contact portion extending diagonally downward toward the opposite side. Then, when the door panel is closed, the second packing abuts the rear surfaces of both ends of the hanging portion with the front surface of the airtight block, and provides the lower surface of the inclined contact portion on the upper surface of the lower frame. This is to contact the inclined receiving surface over the entire length.

[0008]

In the soundproof door apparatus of the present invention having the above-described structure, sufficient sound insulation performance can be exhibited without increasing the force required for pressing the door panel toward the packing. That is, as the door panel is moved to the closed state, the fins of the first packing are formed on the four peripheral edges of the door panel at the back of three edges except the lower edge and the mating member. Close the gap between the front of the. Since the rigidity of the fins is low and the repulsion is small, the elasticity applied to the door panel from the closer causes the first packing and the three edges to be separated from each other without providing a fastening mechanism. The contact can be reliably made over the entire length of one packing.

The gap between the lower edge of the four peripheral edges of the door panel and the upper surface of the lower frame is defined by the inclined contact portion of the second packing mounted on the lower edge and the lower frame. Is closed by making contact with the inclined receiving surface provided on the upper surface of the entire length. Further, a discontinuous portion between both ends of the second packing and both lower ends of the first packing is closed by an airtight block. That is, since these airtight blocks are provided in a continuous state at the lower end of the first packing, the airtightness between the airtight blocks and the lower end of the first packing is maintained. . When the door panel is moved to the closed state, the fins constituting the first packing are crushed, and the front surface of the first packing and the front surface of each of the airtight blocks are located on the same plane. . At the same time, the rear surfaces of both ends of the hanging part constituting the second packing come into contact with the front surfaces of the airtight blocks. As a result, the space between the four peripheral edges of the door panel and the opening frame is closed without gaps over the entire circumference, and sufficient sound insulation is achieved.

Worm wheel teeth are formed on a part of the outer peripheral surface of the sleeve 34, and the worm wheel teeth are meshed with a worm gear 35b rotatably supported on a part of the displacement element 30 only for rotation. Further, a female screw is formed on the inner peripheral surface of the upper half portion of the circular hole 33 formed in the displacement-side element 30, and an adjusting screw 36 is screwed to the female screw. A spherical projection 37 formed on the upper end surface of the support pin member 32 is in contact with the lower surface of the adjusting screw 36.
The upper end opening of the circular hole 33 is closed by a lid piece 38.

According to the hinge member 4 as described above, the height position of the door panel 3 with respect to the opening frame 2 can be adjusted by rotating the adjusting screw 36 with the cover piece 38 removed. You. Further, for example, the support pin member 32 is connected via a worm gear 35a supported by the fixed side element 29.
By rotating, the horizontal position (or front and back position)
Can be adjusted. Further, by rotating the sleeve 34 via, for example, the worm gear 35b supported by the displacement-side element 30, the front-back position (or the left-right position) can be adjusted. After adjustment of each position, the fixing screws 39a, 3
Tighten 9b and 39c so that the adjusted position does not move carelessly.

Also, at the middle part in the height direction of the other end of the door panel 3 in the horizontal direction (right end in FIGS. 1 and 2), FIGS.
The roller 40 is provided with elasticity in a direction protruding from the other end edge.

Such a position adjusting mechanism of the roller 40 and the roller catcher 41 also has a conventionally known structure. Therefore, in brief, the roller 40 rotates the adjusting screw 42 shown in FIG. The amount of protrusion from the holder 66 fixed to the other edge of the door panel 3 is adjustable. The roller catcher 41 can adjust the amount of protrusion from the holder 67 fixed to the vertical frame 7b by rotating the adjusting screws 43, 43 shown in FIG. 44
Is rotated to adjust the position of the holder 67 in the front and back directions.

In the case of the soundproof door device of the present invention configured as described above, sufficient sound insulation performance can be exhibited without increasing the force required to press the door panel 3 toward the packing. That is, as the door panel 3 moves to the closed state based on the elasticity of a closer (not shown), the fins 18, 18 of the first packings 8a, 8b are formed.
There are three edges, excluding the lower edge, of the four peripheral edges of the rear surface of the door panel 3; Close the gap between the front of the. That is, of the first packings 8a, 8b, the first packing 8a provided on the front side is provided with the flanges 10a, 10b, 1 provided at the three edges of the door panel 3.
0c. The first packing 8b provided on the back side is pressed against three edges on the back side of the door panel 3.

The fins 18, 18 constituting each of the first packings 8a, 8b have a low rigidity and a small repulsive force, so that the elasticity applied to the door panel 3 from the closer without any particular fastening mechanism is provided. Thus, the first packings 8a, 8b and the three edges of the door panel 3 can be reliably brought into contact with each other over the entire length of the first packings 8a, 8b. In addition, in the case of the illustrated example, the fin 18 is elastically deformed until it is substantially parallel to the front surface of the fitting and locking portion 15, and the leading edge of the fin 18 Abuts the side of Article 19. Therefore, the contact pressure between the fin portion 18 and the front surface of the mating member can be maintained at an appropriate level, and the contact portion can be reliably closed.

The gap between the lower edge of the four peripheral edges of the door panel 3 and the upper surface of the lower frame 6 which forms the lower edge of the opening frame 2 is provided at the lower edge. The inclined contact portion 26 of the second packing 9 and the inclined receiving surface 27 provided on the upper surface of the lower frame 6 are closed by contact over the entire length.

Further, a discontinuous portion between both ends of the second packing 9 and both lower ends of the first packing 8a on the front side of the first packings 8a and 8b is formed by the airtight block. 21 and 21 are closed. That is, since these airtight blocks 21 and 21 are provided in a continuous state at the lower end of the front first packing 8a, the airtight blocks 21 and 21 and the front first packing 8a are respectively provided. The airtightness with the lower end portion is maintained. When the door panel 3 is moved to the closed state, the fins 18 constituting the first packing 8a on the front side are crushed, and the front surface of the first packing 8a on the front side and the airtight blocks 21 are closed. , 21 are located on the same plane. At the same time, the rear surfaces of both ends of the hanging portion 25 constituting the second packing 9 abut against the front surfaces of the airtight blocks 21 and 21.

As a result, the space between the four peripheral edges of the door panel 3 and the opening frame 2 extends all around the installation portion of the first packing 8a and the second packing 9 on the front side. The space is closed without gaps, and sufficient sound insulation is achieved. In addition, the force of pressing the packings 8a, 8b, 9 against the opposing surface is sufficient only by the elasticity of the closer, so that no extra labor is required when closing the soundproof door device. Further, when opening the soundproof door device, it is sufficient to only push and open the door panel 3 against the elasticity of the closer. Therefore, opening and closing of the soundproof door device is easy.

In the case of the soundproof door device of the present invention, in order to exhibit sufficient sound insulation performance, the door panel 3 supporting the second packing 9 and the first packings 8a, 8a are required.
It is necessary to appropriately regulate (for example, with an accuracy of about ± 1 mm) the positional relationship with the opening frame 2 supporting b. In the case of this example, the position of the door panel 3 with respect to the opening frame 2 can be finely adjusted in the three-dimensional direction by the hinge members 4 and 4, so that the first and second packings 8a are provided. , 8
By setting the pressed state of b and 9 to appropriate, sufficient sound insulation performance can be exhibited. The roller 40 and the roller catcher 4
Since the position of 1 is also adjustable by the adjusting screws 42 to 44, even if the position of the door panel 3 is adjusted,
The roller 40 and the roller catcher 41 can be smoothly and reliably engaged and disengaged. Note that these rollers 40
Engagement between the roller catcher 41 and the roller catcher 41 has a large degree of freedom in the vertical direction (even if it is slightly shifted in the vertical direction,
Since the engagement and disengagement do not become unstable), the illustrated example does not incorporate an adjustment mechanism particularly in the vertical direction.

Next, FIGS. 21 to 22 show a second embodiment of the present invention corresponding to the first and seventh aspects. In the case of the first example described above, since the required sound insulation performance is not so high, of the double packings 8a and 8b, only the space between the lower ends of the first packings 8a on the front side is used. It is closed by the second packing 9. On the other hand, in the case of this example, in order to provide in a part where higher sound insulation performance is required, with the closing of the door panel 3,
The space between the lower ends of the first packing 8b on the back side (the right side in FIG. 21) is also closed.

The back side first packing 8b
Is displaced by a considerable length along the upper surface of the lower frame 6 constituting the opening frame 2 when the door panel 3 is opened and closed. Therefore, if a structure is adopted in which the packing to be bridged between the lower ends of the first packing 8b on the back side is fixed to the lower edge of the door panel 3, this packing and the lower frame 6 Are rubbed against each other, and the force required to open and close the door panel 3 is unnecessarily large. For this reason, in the case of this example, a fourth packing 45 is provided at a position near the lower edge rear surface of the door panel 3 so as to be movable up and down.

For this purpose, a cylinder space 46 is provided over the entire length of the lower edge of the door panel 3 near the rear surface of the lower edge thereof, and a lifting frame 47 is provided in the cylinder space 46 so as to be movable up and down. I have. In addition, a seal member (not shown) is attached to the elevating frame 47 over its entire length to maintain the airtightness of a sliding contact portion between the elevating frame 47 and the cylinder space 46. Then, the lifting frame 47 is moved by a known lifting mechanism.
As the door panel 3 opens and closes, it can be driven up and down freely. That is, a leaf spring (not shown), which is located above the elevating frame 47 and is located deep inside the cylinder space 46, is disposed substantially horizontally over substantially the entire length of the cylinder space 46. The leaf spring has a resilience in a direction in which the plate spring is linear in a free state, and is slightly curved in a direction in which the lower surface side of the intermediate portion is convex in the state of being disposed in the cylinder space 46.
One end of the leaf spring is connected to hinge members 4 and 4 (FIGS. 1 to 4).
2), is fixedly connected to a portion fixed to the door panel 3 and the upper surface of the intermediate portion of the lifting frame 47 is connected to the lower surface of the intermediate portion. Further, the other end of the leaf spring is connected to a base end of a projecting rod (not shown), and the distal end of the projecting rod is connected to the door at the edge on the hinge members 4 and 4 side. It protrudes from the edge of the panel 3. Further, a fourth packing 45 as shown in detail in FIG. 22 is supported on the lower surface of the lifting frame 47 over the entire length of the lower edge of the door panel 3.

In the case of this embodiment in which the fourth packing 45 is supported so as to be able to move up and down by the structure as described above, the fourth packing 45 is lowered only when the door panel 3 is displaced to the closed state. Thus, a gap between the lower edge of the door panel 3 and the upper surface of the lower frame 6 is closed between both lower ends of the first packing 8b on the back side. That is, when the door panel 3 is displaced to the closed state, the distal end surface of the protruding rod abuts on the inner surface of one of the vertical frames constituting the opening frame 2 and is pushed into the door panel 3. As a result, the degree of bending of the leaf spring in which the protruding rod is connected to the distal end thereof increases, and the elevating frame 47 connected to the intermediate portion of the leaf spring descends, and The fourth packing 45 is pressed against the upper surface of the lower frame 6. In this state, the back of both ends of the fourth packing 45 is connected to the first packing 8 on the back side.
b, the first packing 8
Close the gap between both lower ends of b.

On the other hand, when the door panel 3 is displaced to the release side, the leaf spring causes the protruding rod to protrude from the edge of the door panel 3 and reduces the amount of flexure thereof, and The fourth packing 45 through the frame 47
To rise. As a result, the lower surface of the fourth packing 45 and the upper surface of the lower frame 6 are separated from each other, and the lower surface of the fourth packing 45 and the upper surface of the lower frame 6 are rubbed with the opening and closing of the door panel 3. Things disappear. Therefore, regardless of the structure capable of exhibiting high sound insulation performance, the door panel 3
The force required to open and close the door can be reduced. Other configurations and operations are the same as in the case of the above-described first example.

Next, FIGS.
9 shows a third example of the embodiment of the present invention corresponding to FIG. In the case of this example, the door panel 3 is provided inside the opening frame 2a.
a and 3b are built in a double door type. That is,
Two upper and lower hinge members 4, 4 are provided between one vertical edge of one door panel 3a (right side in FIG. 23) and one vertical frame 7a of the opening frame 2a, and the other (FIG. 23). Upper and lower two hinge members 4, 4 are provided between one vertical edge of the door panel 3b (left) and the other vertical frame 7b. Also, the opening frame 2
Is provided between the upper frame 5a and the upper end of the front surface of the one door panel 3a for urging the door panel 3a in the closing direction.

The upper frame 5a constituting the opening frame 2a
Further, a French lock 48 as shown in FIGS. 25 to 27 is provided between the lower frame 6a and the upper and lower edges of the other door panel 3b. Normally, the upper and lower ends of the other edge of the other door panel 3b are connected to the upper frame 5a and the lower frame 6 constituting the opening frame 2a by the French lock 48.
The other door panel 3b cannot be opened and closed by being connected to the intermediate portion of a. Then, the user enters and exits a studio or the like by opening and closing the one door panel 3a.
