Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a sound insulation structure used as a partition wall or a door for closing an opening, which has a sound insulation function and divides a wide indoor space into an appropriate size.

[0002]

2. Description of the Related Art Recent halls, gymnasiums, and theaters, for example, are formed so that the building side has a wide indoor space in advance in the lateral direction. In such a case, there is a tendency that a wall, that is, a partition wall is provided so as to be divided into an appropriate area.

[0003] In this case, the partition wall is often set to have a sound insulation function, and various sound insulation structures for realizing the sound insulation function have been proposed in the past, but generally. A panel serving as a partition wall for partitioning an indoor space formed by the skeleton side when the panel is erected, and a packing disposed on the panel and adjacent to the skeleton side when the panel is erected.

The panel is, of course, formed of an appropriate sound insulator. For example, the panel is suspended on the ceiling side, which is a building side forming an indoor space, and is lowered to a fixed position when used. It is set so that it is set up and stored when not in use, or is stored in a pit below the floor when not in use, and is raised when used.

In many cases, the packing is formed of a sound insulator and is directly connected to the panel.
It is set to have a sound insulator that appears and disappears at the end face of the panel due to the operation of the advance / retreat mechanism.

Therefore, according to the above-described conventional sound insulation structure, the partition wall having the sound insulation function at a predetermined position can be provided only by raising and lowering the panel or by raising and lowering the panel with the sound insulator being protruded and retracted. It has the advantage of enabling installation.

However, the above-mentioned sound insulation structure requires a high ceiling space for storing panels and a deep underfloor space for storing panels, and these spaces cannot be formed or secured. In such a case, there is a problem that it becomes difficult to equip the partition wall itself.

In the above-mentioned sound insulation structure, when the packing made of the sound insulation body is directly connected to the panel, if the reduction of the sound insulation function due to so-called hetering is not taken into consideration, a predetermined There is a fear that a malfunction that the sound insulation function cannot be exhibited may be caused.

Further, in the above sound insulation structure, when the sound insulator is set so as to protrude and retract at the end face of the panel by the operation of the advance / retreat mechanism, the advance / retreat mechanism is provided on the panel.
This tends to increase the size and weight of the panel, increase the cost of installation, and increase the cost of use.

The present invention has been made in view of the above circumstances, and has as its object to realize a desired sound-insulating partition or a sound-insulating door with a simple structure, and It is an object of the present invention to provide a sound insulation structure which can be reduced in cost and is most suitable for expecting improvement in versatility.

[0011]

SUMMARY OF THE INVENTION In order to achieve the above-mentioned object, the construction of the present invention basically includes a partition wall for partitioning an indoor space formed by the skeleton when standing, or an opening formed on the skeleton. It has a panel which is a door to be closed and a packing which is attached to the panel while being rich in elasticity and which is adjacent to the skeleton side when the panel is erected, and the packing is a surface facing the erected surface on the skeleton side. The front part arranged in the shape of a gate around the front part of the panel, and the lower surface of the panel, which faces the floor on the skeleton side, are line-shaped along the axial direction, which is the width direction of this panel. It is assumed that the packing has a lower surface portion, both lower ends of the front surface portion are connected to both ends of the lower surface portion, and the packing is wound around the panel.

More specifically, it is assumed that the packing has two elastic members, and one sound absorber is disposed between the two elastic members.

Further, the panel moves up and down along with guide rails arranged near both ends in the width direction, and the guide rail bends the lower end so as to approach the erected surface on the skeleton side. It is assumed that the lower surface of the panel is adjacent to the floor surface on the skeleton side and the peripheral portion of the front surface of the panel is adjacent to the upright surface on the skeleton side with the packing interposed at the time of secondary lowering.

Further, in a state where the lower surface of the panel is in a standing state in the standing state of the panel adjacent to the floor surface on the frame side with the packing interposed therebetween, the upper end side of the peripheral portion on the front surface of the panel has a gap in the vertical surface on the frame side. When an external force is applied by an appropriate pressing means against the upper end of the rear surface of the panel in the standing preparation state, the upper end of the peripheral portion of the front surface of the panel is adjacent to the standing surface on the skeleton side with the packing interposed therebetween. I do.

[0015]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the drawings. As shown in FIGS. 1 and 2, a partition wall according to an embodiment of the present invention comprises:
The sound insulation structure according to the present invention is embodied, and includes a panel 1 and a packing 2.

In the embodiment shown in the drawings, the panel 1 constitutes a partition wall for partitioning an indoor space A (see FIG. 2) formed by the frame B (see FIG. 2) when standing, that is, a wall. However, instead of this, as shown in FIG. 5 to be described later, it may be set to constitute a door that closes the opening O formed on the skeleton B side.

First, as shown in FIGS. 3 and 4, for example, the panel 1 has a predetermined mechanical strength as a wall while being reduced in weight by adopting an appropriate structure such as a honeycomb structure. In addition, a core material 11 formed into a single plate so as to have excellent sound insulation properties, a front surface (not shown) serving as a lower surface in FIG. 3 of the core material 11 and a back surface serving as an upper surface in FIG. (Not shown), each having a decorative material 12 formed so as to have a sound insulating effect and a decorative effect.

As a result, the weight of the panel 1 can be reduced, and it is not necessary to increase the size of a drive source (not shown) for raising and lowering the panel 1, and in particular, it is possible to expect high sound insulation performance. In addition, it is possible to prevent the viewer from causing a sense of discomfort.

On the other hand, the panel 1 has a bracket 13 on each of both right and left ends in FIG.
Panel 1 of this bracket 13 which is in the horizontal direction in FIG.
The shaft 1 also protrudes in the width direction of the panel 1, that is, on the upper and lower sides of the side surface 13a facing the axial direction.
4, and a roller 15 connected to a guide rail 3 described later is pivotally connected to the shaft 14 (see FIG. 2).

Incidentally, as long as the stable arrangement state of the roller 15, that is, the shaft 14, can be maintained permanently,
For example, the arrangement of the bracket 13 is omitted and the shaft 14
May be directly implanted in the core material 11.

Next, the packing 2 is integrally attached to the panel 1 while being rich in elasticity.
In the present invention, the front surface 1a of the panel 1 which is a surface facing the standing surface B1 (see FIG. 2) on the skeleton B side in the present invention.
1 (see FIG. 1), and a lower surface 1b (see FIG. 1) of the panel 1 serving as a surface facing the floor B2 (see FIG. 2) on the frame B side. (See FIG. 1) and a lower surface portion 2b arranged linearly along the axial direction of the panel 1.

The packing 2 is formed such that both lower ends of a front surface portion 2a and both ends of a lower surface portion 2b are connected to each other, and are wrapped around the panel 1 in an infinite band shape (see FIG. 1). As a result, a so-called gap does not appear over the entire area around the packing 2, so that sound leakage and air leakage caused by the gap can be prevented beforehand.

The packing 2 has two elastic members 21 and a single sound absorbing member 22 disposed between the two elastic members 21 in the illustrated embodiment.

That is, as shown in FIGS. 3 and 4,
In the illustrated embodiment, the elastic body 21 is formed in a tubular shape with an elastic material such as rubber, and is normally filled with air and is in an expanded state. Elevated surface B1 or floor surface B2 (see FIG. 4)
To the floor B1 or the floor B2
According to the above-mentioned embodiment, the so-called familiar contact is made so that a gap that causes sound leakage or air leakage does not appear.

Incidentally, the elastic body 21 has a so-called base end connected to a frame 21a connected to the bracket 13, and a so-called distal end having the above-described standing surface B1 or floor surface B1.
It is said that it touches 2.

The elastic body 21 is not formed in a tubular shape with an elastic material such as rubber, but is formed in a solid body, that is, in a rod shape with a sponge material or a foamable urethane material having high elasticity. It is good.

On the other hand, the sound absorbing body 22 is formed in a rod shape with felt having a rectangular cross section, and the so-called length is set to be longer than the above-mentioned frame 21a. The length is set so as not to protrude from the tip.

Thus, when the elastic body 21 is adjacent to the standing surface B1 or the floor surface B2 on the skeleton B side, the tip of the sound absorbing body 22 is moved in accordance with the deformation amount.
2 so that at this time
If the sound which might leak with the elastic body 21 alone is
Will be absorbed.

Further, since the sound absorbing member 22 is made of felt, the rigidity thereof is higher than that of the elastic member 21 made of an elastic material, and therefore, the sound absorbing member 22 functions to suppress unnecessary deformation of the elastic member 21. This also improves the durability of the elastic body 21.

In the embodiment shown in the drawings, the panel 1 formed as described above is, as shown by a phantom diagram in FIG.
Further, as shown in FIG. 3, the panel 1 is set so as to move up and down along the guide rails 3 arranged adjacent to each other in both sides in the width direction of the panel 1 in a vertical relationship.

The guide rail 3 is set so that the lower end is curved so that the lower end approaches the vertical surface B1 of the frame B, and the panel 1 descends along with the guide rail 3. Sometimes, the lower surface 1b of the panel 1 is on the floor B2 on the skeleton B side, and the periphery of the front surface 1a of the panel 1 is
It is stated that the packing 2 is brought into close contact with the standing surface B1 on the side thereof in a state where the packing 2 is pressed against each other.

The guide rail 3 is provided in the indoor space A.
Is held on the wall B3 on the skeleton B side (see FIG. 3), while the upper end is held on the skeleton B side by appropriate means and extends to the ceiling, which is the upper space of the indoor space A. And

In the illustrated embodiment, the upper end of the guide rail 3 extends in the horizontal direction on the ceiling side. When the panel 1 is located on the ceiling side, the upper end side is in a so-called side-down state. As a result, care is taken not to make the ceiling space unnecessarily high.

Therefore, when the space on the ceiling side is extremely high, for example, when there is a high ceiling space above the stage of a theater, the upper end of the guide rail 3 is set to rise straight. Of course, it is good.

As described above, since the lower end of the guide rail 3 is curved and the lower end is set so as to approach the vertical surface B1 of the skeleton B, the panel 1 is connected to the guide rail 3.
It is possible to separate the indoor space A only by lowering the packing 2 at the same time, and at this time, the panel 1 divides the packing 2 by its own weight using the standing surface B1 on the skeleton B side and the floor surface B2. As a result, a desired sound insulation function can be exhibited without requiring an external force action.

That is, taking into account that this type of movement of the panel 1 such as lifting and lowering and so-called setting is often realized by an external force action using an appropriate drive source, this embodiment is implemented. In the embodiment, these driving sources are not required, and no manual operation is required.

Incidentally, the elevation of the panel 1 along the guide rail 3 may be performed by any means. For example, although not shown, when the panel 1 is placed sideways so as to be present on the ceiling side, the panel 1 In the case where the panel 1 is lifted while the panel 1 is in an upright state, each is realized by towing a hanging wire or the like connected to a lower end portion of the panel 1 by pulling a hanging wire or the like connected to an upper end of the panel 1. become.

FIG. 5 shows an embodiment in which the sound insulation structure of the present invention is embodied as a door that closes an opening O formed on the skeleton B side. In this embodiment, a panel 1 serving as a door is shown.
Is moved down along the guide rail 3 and is brought close to the skeleton B side with the packing 2 interposed therebetween. In particular, in the procedure in which the front surface 1a of the panel 1 is brought close to the upright surface B1 on the skeleton B side. The present embodiment is characterized in that it differs from the embodiment described above.

That is, in this embodiment, the panel 1
Is lowered and the lower surface 1b of the panel 1 is placed near the floor B2 on the side of the skeleton B with the packing 2 interposed therebetween in a standing preparation state (in a state shown by a phantom diagram in FIG. 5). The upper end of the peripheral portion of the front surface 1a of the panel 1 faces the standing surface B1 on the skeleton B side with a gap, and the panel 1 in the standing preparation state is provided.
The panel 1 is erected by an external force acting on the upper end side of the rear surface 1c of the front surface 1c by an appropriate pressing means 4, and the upper end side of the peripheral portion of the front surface 1a is brought close to the standing surface B1 on the skeleton B side with the packing 2 interposed therebetween ( (See the solid line diagram in FIG. 5).

In other words, it is assumed that the foot is first positioned at a predetermined position, and then the opening O is entirely closed and the sound is shielded. In the above-described embodiment, when the panel 1 is lowered, so to speak. The lower surface 1b of the panel 1 is on the floor surface B2,
Further, this is different from the point that the front surface 1a of the panel 1 is simultaneously adjacent to the upright surface B1 with the packing 2 interposed therebetween (see FIG. 2).

In this embodiment, the panel 1, which is a door, can be maintained in a predetermined standing state by the external force of the pressing means 4, so that the panel 1 is not easily opened even by a large wind pressure from outside. It becomes possible to do.

To explain a little, first, the panel 1 is shown in FIG.
As shown in the figure, a bracket 1 is provided at the upper end of the back surface 1c.
And a roller 17 held by the roller 1.
7 is maintained in a predetermined upright state by the pressing action from the pressing means 4 via the roller 7, and is in a semi-open state by the so-called pulling action by the pressing means 4 via the roller 17, ie It is going to be in a state.

In this embodiment, the panel 1
The winch W as a drive source disposed on the skeleton B side is driven up and down along the guide rail 3 by driving the winch W. One end of a suspension wire W1 drawn from the winch W is connected to the lower end of the panel 1. (See FIG. 5).

Next, in this embodiment, the pressing means 4 has a hydraulic cylinder 41 disposed horizontally on the indoor side behind the panel 1, as shown in FIG. The base end 41a of the hydraulic cylinder 41 is set to the fixed end side, and the holder 4
2 is detachably connected to the roller 17 on the back surface 1c of the panel 1.

Then, the holder 42 holds the roller 17 in FIG.
And a pair of locking plates 42a and 42b which are set so as to be sandwiched from the front and rear sides, which are the left and right sides, and have an interval corresponding to the width of the guide rail 3. When the hydraulic cylinder 41 is extended with the roller 17 in contact with the stop plate 42a, the panel 1 can be erected through the roller 17 and the front locking plate 42b
When the hydraulic cylinder 41 is compressed in a state where the roller 17 is in contact with the panel 1, the panel 1 can be tilted via the roller 17.

Therefore, in this embodiment, the panel 1 in the housed state shown by the phantom diagram in FIG. 5 is allowed to pull out the hanging wire W1 from the winch W from this state. With its own weight, it descends along the guide rail 3 and its lower end is positioned at a predetermined position, and is ready for standing.

At this time, the roller 17 held by the panel 1 falls out of the opening end of the guide rail 3 in a so-called dropping manner, and is connected to a holder 42 provided in the pressing means 4 and connected to the hydraulic cylinder 41.

The panel 1 in the upright preparation state is shifted to the upright state via the holder 42 and the roller 17 when the pressing means 4 extends the hydraulic cylinder 41, that is, to a predetermined upright state.

Contrary to the above, the panel 1 in the standing state
Is tilted via the holder 42 and the roller 17 due to the compression of the hydraulic cylinder 41, that is, is returned to the standing preparation state, which is a half-open state.

At this time, the roller 17 held by the panel 1 is positioned below the open end of the guide rail 3, so that when the panel 1 is lifted by the hanging wire W1 in this state, It escapes and is linked to the guide rail 3.

When the suspension wire W1 is further wound up in this state, the guide rail 3
In other words, in the illustrated embodiment,
It is stored in a so-called horizontal state on the ceiling side indoors.

Therefore, in the case of this embodiment, it is of course possible to close the opening O formed on the skeleton B side by lowering the panel 1 along the guide rail 3. At this time, since the panel 1 is pressed against the skeleton B by the external force from the pressing means 4, the desired sound insulation function can be reliably exhibited.

In this embodiment, since the panel 1 is pressed against the frame B by the pressing means 4, the elastic body 21 of the packing 2 is provided as in the above-described embodiment. Instead of being formed in a tubular shape with an elastic material such as rubber, it is better to be formed of a solid body made of urethane material that has a relatively high rigidity and is not easily deformed in comparison. In particular, it can be said to be preferable from the viewpoint of preventing rainwater and wind from entering from outside and from the viewpoint of expecting durability.

What has been described above is a basic feature of the sound insulation structure in the embodiment shown in FIG. 5. Considering that the pressing means 4 moves together with the movement of the panel 1 as described below. May be.

That is, it is assumed that the base end 41a of the hydraulic cylinder 41 constituting the pressing means 4 is pivotally supported by the bracket 43, and the bracket 43 is movably connected to the rail R disposed on the ceiling side.

Thus, after the panel 1 is ready to be erected, the hydraulic cylinder 41 is maintained in a so-called free state in which the hydraulic cylinder 41 can freely expand and contract, so that when the panel 1 is stored in a horizontal state, The hydraulic cylinder 41 moves along with the expansion and contraction following the movement of the panel 1 following the guide rail 3.

As a result, the tip 41b of the hydraulic cylinder 41
The roller 17 provided on the panel 1 is provided on the holder 42
Can always be maintained in a linked state, so that a so-called connection error between the guide rail 3 and the holder 42 can be prevented.

[0058]

As described above, according to the present invention, a partition wall which partitions the indoor space formed by the skeleton when standing upright or a panel which is a door which closes the opening formed on the skeleton side is integrally provided. The front part is arranged so that the packing adjacent to the skeleton side when the panel is erected is rich in elasticity and has a gate shape around the front part of the panel which is the opposite side to the vertical side on the panel skeleton side. The lower surface of the panel, which faces the floor surface on the skeleton side, has a lower surface arranged in a line along the axial direction which is the width direction of the panel, and has both lower ends and a lower surface of the front surface. Since both ends are connected and the packing is circulated on the panel, this packing is closely contacted with the skeleton side, so that a so-called gap does not appear over the entire area where the packing is circulated. There is sound leakage and air caused by By preventing Les in advance, so that can realize a reliable sound insulation.

At this time, in the case where the packing has two elastic members and one sound absorbing member is disposed between the two elastic members, the elastic member is formed of an elastic material such as rubber and has a tubular shape. By being formed on the body side, when it is adjacent to the skeleton side, it adheres so as to be familiar, so that no gap that causes sound leakage or air leakage appears, and the sound absorbing body is formed in a rod shape with felt By forming the so-called length not to protrude from the tip of the elastic body in the free state,
When adjacent to the skeleton side, this sound absorbing body absorbs the sound that may be leaked by the elastic body alone.
Since the sound absorber is made of felt, the rigidity is higher than that of an elastic body made of an elastic material, and therefore, the elastic body functions to suppress unnecessarily deformation, thereby improving the durability of the elastic body. It will also improve.

Further, according to the present invention, the panel moves up and down along with the guide rails disposed adjacent to the both ends in the width direction, and the guide rail curves at the lower end to approach the standing surface on the skeleton side. When lowering the panel along the guide rail of the panel, the lower surface of the panel is adjacent to the floor surface on the skeleton side, and the periphery of the front surface of the panel is adjacent to the vertical surface on the skeleton side with the packing interposed, respectively. Is not only possible to separate the indoor space by simply lowering the panel along the guide rail, but also at this time, the panel will press the packing against the frame by its own weight. , As a result, without the need for external force action,
Since no external force action is required using an appropriate drive source, a desired sound insulation function can be exhibited without requiring these drive sources and without requiring manual operation.

Furthermore, according to the present invention, the upper end of the peripheral portion of the front surface of the panel is placed on the frame side when the panel is ready to be erected near the lower surface of the panel on the floor surface of the frame side with the interposition of packing. The upper surface of the front surface of the panel at the time of external force by an appropriate pressing means against the upper surface of the rear surface of the panel in the preparation state for standing, and the upper surface of the peripheral portion of the panel is provided with When it is assumed that the panel is located under the intervention, it is possible to make the panel adjacent to the skeleton side by lowering the panel along the guide rail, and at this time, the panel is pressed from the pressing means. As a result, the desired sound insulation function can be surely exhibited.

In this case, since the panel is pressed against the skeleton side by the pressing means, the elastic body in the packing is made of an elastic material such as rubber in the form of a tube. In other words, it is possible to form a solid body made of urethane material, which has a higher rigidity, so that it does not easily deform, especially when the panel is set as a door that closes an opening that leads to the outdoors.
This is advantageous in that the waterproof function and durability of the packing can be improved.

As a result, according to the present invention, it is possible to realize a desired function as a sound-insulating partition wall or a sound-insulating door with a simple structure, and to reduce the cost and improve its versatility. There are advantages that are most suitable for:
