Description

  The present invention relates to a soundproof partition that is used, for example, for partitioning rooms in a building and prevents sound from passing between rooms.

  2. Description of the Related Art Conventionally, a soundproofing partition comprising a pair of face materials arranged so as to be spaced apart from each other and a sound insulation member for blocking sound transmission from one face material side to the other face material side is known. (For example, refer to Patent Document 1). The sound insulation member is disposed between the face materials so as to cover the face materials entirely, and is fixed integrally to the face materials by being bonded to the mutually facing surfaces of the face materials. .

According to this soundproof partition, when sound generated in one of the two rooms partitioned by the soundproof partition passes through one face material located on the room side and enters the sound insulating member, the sound is separated. A part of the energy of the sound insulation member is consumed as reflected sound energy reflected from the sound insulation member according to the mass and rigidity of the sound insulation member, and a part of the sound energy is converted into heat energy in the sound insulation member. To be consumed. Thereby, since the energy of the sound which permeate | transmits a sound insulation member becomes smaller than the energy when entering a sound insulation member, it is suppressed that the sound which injected into the sound insulation member permeate | transmits this sound insulation member to the other surface material side. . Therefore, since the sound generated in the one room is prevented from propagating to the other room through the soundproof partition, it is possible to suppress the sound generated in the one room from leaking to the other room. it can.

  By the way, for example, when one room partitioned by a soundproof partition is a care room and the other room is a caregiver's waiting room, the cared person's voice is heard in the waiting room during the day when the cared person is awake. Therefore, it is necessary to prevent the sound in the waiting room from being heard in the nursing room at night when the care recipient is sleeping.

  However, since the conventional soundproofing partition is not provided with means for actively reducing the degree of sound insulation, when the conventional soundproofing partition is used to partition the care room and the waiting room, for example, Although it is possible to block the sound in the waiting room from being heard in the care room, the voice of the cared person cannot be heard in the waiting room.

  In order to reduce the degree of sound insulation of the sound insulation partition, it is conceivable to remove a part of the sound insulation member from between each face material in order to form a non-sound insulation space where no sound insulation member exists between each face material. Since it is integrally fixed to each face material by being bonded to each face material, it is necessary to partially peel the sound insulating member from each face material. Moreover, in order to return the sound insulation degree of the soundproof partition to the original degree, it is necessary to adhere the peeled sound insulation member to each face material again. For this reason, every time the sound insulation degree of the soundproof partition is adjusted, it is necessary to perform the work of separating and adhering the sound insulation member, which makes it difficult to adjust the sound insulation degree of the soundproof partition.

  Accordingly, an object of the present invention is to provide a soundproof partition that can easily adjust the degree of sound insulation as required.

  In order to solve the above-mentioned problem, the invention according to claim 1 is a pair of face materials arranged so as to be spaced apart from each other and facing each other, and arranged between each face material, from one face material side. At least two sound insulation members for blocking the propagation of sound to the other face material side, and at least one of the sound insulation members is in cooperation with the other sound insulation member. It is possible to move between a covering position covering the entire surface of the double-sided material and an overlapping position overlapping the other sound insulating member.

  According to a second aspect of the present invention, in the first aspect of the present invention, each of the sound insulation members is provided with a seal member for hermetically sealing between the two sound insulation members. And

  The invention according to claim 3 is the invention according to claim 1 or 2, characterized in that each of the face materials has light transmittance.

  According to a fourth aspect of the present invention, in the invention according to any one of the first to third aspects, the one sound insulating member may include at least one of the surface members from the sound insulating member. And an operating portion that is operated to move the one sound-insulating member is provided, and the one surface material is allowed to pass through the operating portion. A guide groove is formed for guiding the movement of the operation portion in the moving direction of the sound insulating member when the sound insulating member moves.

  The invention according to claim 5 is the invention according to claim 4, wherein the one sound insulating member is disposed between the one sound insulating member and the one face material, and the guide groove is formed at the covering position. A sealing member for sealing is provided, and the operation unit is provided in the sealing member.

  A sixth aspect of the present invention is the invention according to any one of the third to fifth aspects, wherein each of the sound insulating members has a light transmitting property.

  A seventh aspect of the invention is characterized in that, in the sixth aspect of the invention, the light transmittance of each of the sound insulation members is lower than the light transmittance of each of the face members.

  According to the first aspect of the present invention, at least one of the sound insulating members disposed between the pair of face members is covered with the other covering portion and the other covering member in cooperation with the other sound insulating member. It is possible to move between overlapping positions overlapping with the sound insulating member.

  From this, when the one sound insulation member is moved to the covering position, for example, when passing through one face material and entering each sound insulation member, a part of the energy that the sound has is similar to the conventional case. In addition, it is consumed as reflected sound energy reflected from each sound insulation member according to the mass and rigidity of each sound insulation member, and a part of the sound energy is converted into heat energy in each sound insulation member. Is consumed. Thereby, the energy of the sound which permeate | transmits each sound insulation member becomes smaller than the energy when entering a sound insulation member. Thereby, it is suppressed that the sound which injected into each sound insulation member permeate | transmits this sound insulation member to the other surface material side. This prevents the sound generated on the one face material side from propagating to the other face material side via the soundproof partition.

  On the other hand, when the one sound insulating member is moved from the covering position toward the overlapping position, that is, when the one sound insulating member is partially or entirely overlapped with the other sound insulating member, A non-sound insulation space where no sound insulation member exists is formed between the face materials. Thereby, for example, a part of the sound that has passed through one face material toward the other face material passes through the non-sound insulation region between the face materials without entering each sound insulation member, and the other surface. The light is incident on the material, and passes through the other surface material side of the soundproof partition. Accordingly, by moving the one sound insulation member toward the overlapping position, sound propagation through the sound insulation partition is allowed, so that the sound insulation degree of the sound insulation partition can be reduced.

  Therefore, for example, when one room partitioned by a soundproof partition is a nursing room and the other room is a caregiver's waiting room, during the daytime when the cared person is awake, the one sound insulation member is placed in the covering position. By placing the care receiver in a position that has moved toward the overlapping position, the voice of the cared person can be heard in the waiting room. On the other hand, during the night when the cared person is sleeping, the one sound insulating member Can be prevented from being heard in the nursing room.

  Further, the one sound insulating member can be moved without being fixed to each surface material, and the non-sound insulating space can be formed between the surface materials by moving the one sound insulating member. In order to form the non-sound insulation space between the face materials, the work of peeling the sound insulation member from each face material and the work of bonding the sound insulation member to each face material as in the conventional case where the sound insulation member is fixed to each face material are performed. Compared with the case where it is necessary, the adjustment work of the sound insulation degree of the soundproof partition can be reliably and easily performed.

  According to the second aspect of the present invention, each sound insulation member is provided with a seal member for hermetically sealing between the sound insulation members. From this, for example, when a part of the sound transmitted through one face material propagates between the sound insulation members in a state where the one sound insulation member is in the covering position, the sound is transmitted to each seal member. Reflection and absorption prevent passage of sound between the sound insulation members. Thereby, it can suppress reliably that the sound which generate | occur | produced on the said one surface material side of the soundproof partition penetrates the other surface material side through both sound insulation members.

  According to invention of Claim 3, since each face material has a light transmittance, respectively, when said one sound-insulation member moves toward the said overlapping position from the said covering position, between each face material. When a non-sound insulation space without a sound insulation member is formed, part of the light transmitted through one face material passes through the non-sound insulation space and then passes through the other face material. Thereby, when the soundproof partition is arranged at a position facing the outdoors, for example, sunlight can be taken into the room through the soundproof partition.

  In addition, since the size of the non-sound insulation space can be changed by changing the movement position of the one sound insulation member, it is possible to easily adjust the light intensity according to the movement position of the one sound insulation member. it can.

  According to the invention described in claim 4, the one sound insulation member extends from the sound insulation member toward at least one of the face materials and penetrates the face material, and the one sound insulation member. An operation portion that is operated to move the sound insulation member is provided, and a guide groove that guides the movement of the operation member in the moving direction of the sound insulation member when the one sound insulation member is moved is formed in the one face material. Has been.

  Accordingly, by moving the operation portion along the guide groove in the guide groove by the guide action of the guide groove, the one sound insulating member can be moved without being obstructed by the operation portion. Thereby, compared with the case where the operation | work which moves said one sound insulation member is performed, for example by putting a hand between double-sided materials, the movement operation of said one sound insulation member can be performed easily.

  According to the fifth aspect of the present invention, since the guide groove is sealed by the sealing member in a state where the one sound insulating member is in the covering position, the guide groove is formed from the outside and the inside of the soundproof partition. A part of the sound incident inside is reflected and absorbed by the sealing member. Accordingly, it is possible to reliably suppress the sound from entering the inside of the soundproof partition through the guide groove and the sound entering the soundproof partition from leaking out of the soundproof partition through the guide groove.

  According to the invention described in claim 6, since each sound insulation member has light transparency, for example, when a soundproof partition is arranged between the care room and the waiting room, when the care recipient is sleeping, When the one sound insulation member is placed at the covering position so that the sound in the waiting room does not leak into the care room, the state of the cared person in the care room through each face material and each sound insulation member in a state where sound is insulated by each sound insulation member It can be visually recognized.

  According to invention of Claim 7, since the light transmittance of each sound insulation member is lower than the light transmittance of each surface material, respectively, each sound insulation member can be made to play the role as a blindfold. Thus, for example, when a soundproof partition is arranged between the care room and the waiting room, the privacy of the non-caregiver is greatly prevented without greatly hindering the view of the cared person in the care room through each face material and each sound insulation member. Can be protected.

  The present invention will be described with reference to the illustrated embodiments.

In this state, as described above, the length dimension along the extending direction of each sound insulating member 12, 13, 14 is substantially equal to the height dimension along the vertical direction of each face member 11, and each sound insulating member 12, Since the width dimensions of 13 and 14 are equal to each other and the sum of the width dimensions is set to be substantially equal to the width dimension along the left-right direction of each face material 11, each face material 11 is entirely covered by the sound insulation members 12, 13, and 14, respectively.

  In the illustrated example, the upper frame member 17 and the lower frame member 18 extend along the extending direction of the upper frame member 17 and the lower frame member 18 at positions corresponding to the other two sound insulating members 12 and 13, respectively. A rail 19 for receiving the upper end portions 12a, 13a and the lower end portions 12b, 13b of the other sound insulation members 12, 13 is formed. Each of the other sound insulation members 12 and 13 has an upper frame member 17 and a lower frame member as the upper end portions 12a and 13a and the lower end portions 12b and 13b (see FIG. 1) are guided by the rails 19, respectively. 18 along. That is, each of the other sound insulation members 12 and 13 is movable between the double-sided materials 11 along the left-right direction of the soundproof partition 10. The other sound insulation members 12 and 13 (hereinafter referred to as movable sound insulation members 12 and 13) are moved to overlapping positions overlapping the fixed sound insulation member 14 as shown in FIG. And each vertical frame member 16 are opened at the maximum opening.

  As shown in FIG. 2, each of the movable sound insulation members 12 and 13 and the fixed sound insulation member 14 has a sealing member 20 for hermetically sealing between the movable sound insulation members 12 and 13 and the fixed sound insulation member 14. Is provided.

  In the illustrated example, the seal member 20 is made of an elastically deformable material such as rubber, and is attached to each side end face 12c, 13c, 14c of each of the fixed sound insulating member 14 and each movable fixed member. It is provided so as to extend along the end face.

  Of the side end faces 12c, 13c of each movable sound insulation member 12, 13, each movable sound insulation member 12, 13 cooperates with the fixed sound insulation member 14 to cover each face material 11 (the position shown in FIG. 2). ), The seal member 20 provided on one side end surface 12c, 13c adjacent to each side end surface 14c of the fixed sound insulation member 14 is each surface of the fixed sound insulation member 14 facing each other in the plate thickness direction. 14d, and slides on the surface 14d of the fixed sound insulation member 14 when the movable sound insulation members 12 and 13 are moved.

  Each seal member 20 provided on the fixed sound insulation member 14 is opposite to the surfaces 12d and 13d located on the face material 11 side close to the movable sound insulation members 12 and 13 among the surfaces of the movable sound insulation members 12 and 13, respectively. It abuts on the surfaces 12e and 13e located on the side, and slides on the surfaces 12e and 13e of the movable sound insulation members 12 and 13 when the movable sound insulation members 12 and 13 move.

  Thereby, it is possible to prevent air from passing between the movable sound insulation members 12 and 13 and the fixed sound insulation member 14.

  Further, the seal member 20 provided on the other side end face 12c, 13c of each movable sound insulation member 12, 13 is in close contact with each vertical frame member 16 at the covering position. Thereby, between each movable sound insulation member 12 and 13 and each vertical frame member 16 is airtightly sealed in the said covering position.

  As shown in FIG. 4, each of the movable sound insulation members 12 and 13 is provided with an operation unit 21 that is operated to move each of the movable sound insulation members (FIG. 4 shows one movable sound insulation member. The provided operation unit 21 is shown). In the illustrated example, each operation portion 21 is provided on each of the surfaces of the movable sound insulation members 12 and 13 on the surfaces 12d and 13d located on the face material 11 side close to the movable sound insulation members 12 and 13, respectively. , Each having a pair of column portions 22 and a connecting portion 23 for connecting the both column portions to each other.

  The column portions 22 are arranged at intervals from each other along the vertical direction of the movable sound insulation members 12 and 13, respectively, and the face material adjacent to the surfaces 12 d and 13 d of the movable sound insulation members 12 and 13, respectively. 11 and extends through the face material.

  The connecting portion 23 extends on each face material 11 from the upper end portion 22 a of one column portion 22 toward the upper end portion 22 a of the other column portion 22.

  Each face member 11 is formed with a guide groove 24 that guides the movement of the operation unit 21 in the moving direction of each movable sound insulation member 12, 13 when each movable sound insulation member 12, 13 moves.

  In the illustrated example, the guide groove 24 is formed in each face material 11 corresponding to each column portion 22 of each operation portion 21, and receives each column portion 22. Further, as shown in FIGS. 2 and 3, each guide groove 24 is located at the overlapping position of each movable sound insulation member 12, 13 from a position corresponding to each column portion 22 in the covering position of each movable sound insulation member 12, 13. In FIG. 3, the linearly extends toward the position corresponding to each column portion 22.

  Further, each movable sound insulation member 12, 13 is provided with a sealing member 26 for sealing each guide groove 24.

  In the illustrated example, each sealing member 26 is a plate member formed of lead, and extends along the extending direction of each guide groove 24. Further, each sealing member 26 is configured so that each of the movable sound insulation members 12, 13 covers each guide groove 24 from the inside of the sound insulation partition 10 with each of the movable sound insulation members 12, 13 being in the covering position. 13 are attached to the surfaces 12d and 13d. As shown in FIGS. 2 and 4, the peripheral edge portion 26 a of each sealing member 26 contacts the edge portion 24 b of each guide groove 24 from the inner side of the soundproof partition 10 at the covering position. Thereby, each guide groove 24 is sealed by each sealing member 26 at the covering position. In the example shown in FIGS. 2 to 4, each column portion 22 of each operation portion 21 is fixed to each sealing member 26, and each operation portion 21 is connected to each movable sound insulation member 12, via each sealing member 26. 13 are fixed to the surfaces 12d and 13d.

  When a force toward the central portion in the left-right direction of the soundproof partition 10 is applied to the connecting portion 23, each column portion 22 of each operation portion 21 is guided in each guide groove 24, thereby guiding the inside of the guide groove 24. Move along the groove. At this time, since each of the movable sound insulation members 12 and 13 is subjected to a force from each connecting portion 23 via each column portion 22 toward the overlapping position, each of the movable sound insulation members 12 and 13 has the overlap. It moves integrally with each operation part 21 along the rail 19 toward the position. That is, the movement of each movable sound insulation member 12, 13 is allowed by the movement of each column portion 22 being guided by each guide groove 24. As described above, each guide groove 24 extends from the position corresponding to each pillar 22 at the covering position toward the position corresponding to each pillar 22 at the overlapping position. When the movable sound-insulating members 12 and 13 are moved to the overlapping positions, they are engaged with the end surfaces 24a of the guide grooves 24, respectively. As a result, when the movable sound insulating members 12 and 13 are moved from the covering position toward the overlapping position, the movement of the movable sound insulating members 12 and 13 beyond the overlapping position is prevented. In other words, in the illustrated example, each of the movable sound insulating members 12 and 13 is movable in the left-right direction of the soundproof partition 10 between the covering position and the overlapping position.

  In the present embodiment, the design conditions such as the surface density and weight of each face material 11, each sound insulation member 12, 13, 14, and frame 15 constituting the soundproof partition 10 are the same for each movable sound insulation member 12, 13. The value of the sound insulation grade D representing the sound insulation performance of the entire soundproof partition 10 when placed at the covering position is 20 to 50, and the soundproof partition 10 when the movable sound insulation members 12 and 13 are placed at the overlapping positions, respectively. It is set so that the value of the overall sound insulation class D is 10-20.

  When the soundproof partition 10 according to the present invention is arranged so as to partition two rooms in a building (not shown), one face material in which sound generated in the one room is arranged on the one room side 11, most of the sound passes through the one face member 11 from the one room side to the other room side, and the one face member 11 and the sound insulation members 12, 13, 14. Are propagated toward the respective sound insulation members.

  At this time, when each of the movable sound insulation members 12 and 13 is placed at the covering position, a part of the energy of the sound depends on the mass and rigidity of the sound insulation members 12, 13 and 14. The energy of the reflected sound reflected from the sound insulation member is consumed, and a part of the energy of the sound is consumed by being converted into heat energy in each of the sound insulation members 12, 13 and 14. Thereby, since the energy of the sound which permeate | transmits each sound insulation member 12,13,14 becomes smaller than the energy when entering a sound insulation member, the sound which injected into each sound insulation member 12,13,14 is said one room side To the other room side through the sound insulation members 12, 13, and 14 is suppressed.

  Further, in the state where each movable sound insulation member 12, 13 is placed at the covering position, as described above, between each movable sound insulation member 12, 13 and the fixed sound insulation member 14, and each movable sound insulation member 12. 13 and each vertical frame member 16 are hermetically sealed by respective seal members 20. Therefore, when a part of the sound propagates between the movable sound insulation members 12, 13 and the fixed sound insulation member 14, and between the movable sound insulation members 12, 13 and the vertical frame members 16, the sound is Reflected and absorbed by each seal member 20, the passage of sound between each movable sound insulation member 12, 13 and fixed sound insulation member 14, and between each movable sound insulation member 12, 13 and each vertical frame member 16 is transmitted. Be blocked.

  Thereby, since the sound generated in the one room is suppressed from propagating from the one room side to the other room side through the soundproof partition 10, the sound leaks to the other room. Is suppressed.

  Further, as described above, the space between both side edges 11a of each face material 11 is closed by each vertical frame member 16 made of lead, and lead has a higher surface density than, for example, wood. The value of the transmission loss of sound in the vertical frame member 16 is larger than that of, for example, wood. Thereby, since the sound transmitted through the one face member 11 is further suppressed from transmitting through the vertical frame member 16, the sound is more reliably suppressed from leaking from the inside of the soundproof partition 10 to the side thereof. can do.

  Further, as described above, since each guide groove 24 is sealed by each sealing member 26 at the covering position, the sound incident on each guide groove 24 from the outside and inside of the soundproof partition 10 is transmitted to each sealing member. 26 is reflected and absorbed. Accordingly, it is possible to suppress the sound from entering the inside of the soundproof partition 10 through the guide grooves 24 and the sound entering the soundproof partition from leaking out of the soundproof partition 10 through the guide grooves 24.

  On the other hand, when one or both of the movable sound insulation members 12 and 13 are located at positions moved from the covering position toward the overlapping position, that is, the movable sound insulation members 12 and 13 are part of the fixed sound insulation member 14. When the sound insulation members 12, 13, and 14 do not exist between the fixed sound insulation member 14 and the vertical frame members 16, respectively, the movable sound insulation members 12 are not overlapped. , 13 is formed as a non-sound insulation space S (see FIG. 3) opened at an opening corresponding to the moving position. Thereby, a part of the sound that has passed through the one face member 11 toward the other face member 11 is reflected and absorbed by being incident on the sound insulation members 12, 13, and 14 in the same manner as described above. Part of the sound passes through the non-sound insulation space S without entering the sound insulation members 12, 13, and 14, enters the other face material 11, passes through the face material, and the other side of the soundproof partition 10. It penetrates to the face material 11 side.

  According to the present embodiment, as described above, since each movable sound insulation member 12, 13 is moved toward the overlapping position, sound can be transmitted through the sound insulation partition 10, so that the sound insulation partition 10 The degree of sound insulation can be reduced.

  Thereby, for example, when one room partitioned by the soundproof partition 10 is a care room and the other room is a caregiver's waiting room, the daytime when the care receiver is awakening, By placing either one at the position moved from the covering position toward the overlapping position, the cared person's voice can be heard in the waiting room, while the cared person is sleeping at night By placing the movable sound insulating members 12 and 13 at the covering positions, it is possible to prevent the sound in the waiting room from being heard in the nursing room.

  Further, when the soundproof partition 10 is used to partition between the living room and the child room, when the child concentrates and studies, the movable sound insulating members 12 and 13 are moved to the covering positions to move the living room. The sound is prevented from leaking into the children's room, and when the child in the child's room is working while talking with the person in the living room, the movable sound insulation members 12, 13 are moved to the overlapping positions, respectively. You can have a conversation between the children's room and the living room.

  Furthermore, as described above, each movable sound insulation member 12, 13 can be moved without being fixed to each face material 11, and each movable sound insulation member 12, 13 can be moved by operating each operation portion 21. The non-sound insulation space S can be formed between the face members 11. From this, in order to form the non-sound insulation space S between the face members 11, the work for separating the sound insulation members from the face members 11 and the sound insulation member as in the prior art in which the sound insulation members are fixed to the face members 11 are performed. Compared to the case where an operation for bonding the sound insulating partition 10 to each face member 11 is necessary, the adjustment operation of the sound insulation degree of the soundproof partition 10 can be reliably and easily performed.

  Further, as described above, since each face material 11 is made of a material having light transmittance, each face material is moved by moving each movable sound insulation member 12, 13 from the covering position toward the overlapping position. When the non-sound insulation space S is formed between 11, a part of the light transmitted through one of the face materials 11 passes through the non-sound insulation space S and then passes through the other face material 11. Thereby, when the soundproof partition 10 is arrange | positioned in the position which faces the outdoors, for example, sunlight can be taken in indoors through the soundproof partition 10.

  In addition, since the size of the non-sound insulation space S can be changed by changing the movement position of each movable sound insulation member 12, 13, the amount of light collected can be changed according to the movement position of each movable sound insulation member 12, 13. Can be easily adjusted.

  Further, as described above, the movable sound insulation members 12 and 13 are moved to the respective operation portions by moving the respective operation portions 21 along the respective guide grooves 24 by the guide action of the respective guide grooves 24. 21 can be moved without being obstructed. Thereby, compared with the case where the operation | work which moves each movable sound-insulation member 12 and 13 is performed, for example by putting a hand between the double-sided materials 11, the movement operation | work of each movable sound-insulation member 12 and 13 can be performed easily.

  In the present embodiment, an example is shown in which the movable sound insulation members 12 and 13 are disposed between the double-sided materials 11 so that the movable sound insulation members 12 and 13 can move in the left-right direction of the soundproof partition 10. Instead, as shown in FIG. 5, the movable sound insulation members 12, 13 may be disposed between the double-sided members 11 so that the movable sound insulation members 12, 13 can move in the vertical direction of the soundproof partition 10. it can.

  In the example shown in FIG. 5, each sound insulating member 12, 13, 14 extends in the left-right direction of the soundproofing partition 10, and each face material 11 so that the respective plate thickness directions substantially coincide with the thickness direction of the soundproofing partition 10. Arranged between. Further, the sound insulation members 12, 13, and 14 do not overlap each other in the vertical direction of the soundproof partition 10, and the arrangement positions between the double-sided materials 11 are mutually different in the thickness direction of the soundproof partition 10. It is arranged between the double-sided materials 11 so as to shift by 14 thicknesses.

  Moreover, in the example shown in FIG. 5, the fixed sound insulation member 14 is arrange | positioned among the sound insulation members 12, 13, and 14 in the center part of the up-down direction of the soundproof partition 10 between the double-sided materials 11, and each edge part has it. It is fixed to each vertical frame member 16. In addition, one of the movable sound insulation members 12 and 13, which is located on the lower side in FIG. 5, is disposed so as to close the space between the fixed sound insulation member 14 and the lower frame member 18. The other movable sound insulation members 12 and 13 are disposed so as to close the space between the fixed sound insulation member 14 and the upper frame member 17. Each of the movable sound insulation members 12 and 13 moves in the vertical direction of the soundproof partition 10 along a rail 25 formed on each vertical frame member 16 so as to extend along the extension direction thereof.

  According to the example shown in FIG. 5, when the soundproof partition 10 is disposed in the building at a position facing the outdoors, the movable sound insulation members 12 and 13 located on the upper side are placed at overlapping positions overlapping the fixed sound insulation member 14 in the daytime. By opening the upper space between the double-sided materials 11 by this, sunlight can be taken into the building from the outside through the upper space, and the line of sight from the outside is fixed to the sound insulation member 14 and the lower movable sound insulation. It can be blocked by the members 12 and 13. Further, when each face material 11 is made of a transparent member, the lower movable sound insulation members 12 and 13 are placed at the overlapping positions so as to open the lower space between the both surface materials 11, thereby allowing the outdoor space through the lower space. Can be seen from inside the building.

  On the other hand, at night, each movable sound insulation member 12, 13 is placed in a covering position that covers the entire face material 11 in cooperation with the fixed sound insulation member 14, thereby preventing outdoor sound from entering the building. can do.

  In the example shown in FIG. 5, when each movable sound insulation member 12, 13 moves from the covering position toward the overlapping position, a holding means (not shown) for holding each movable sound insulation member 12, 13 at each movement position. Can be provided, for example, between each vertical frame member 16 and each movable sound insulation member 12,13.

  In the example shown in FIGS. 1 to 5, each sound insulation member 12, 13, 14 can be made light transmissive by making each sound insulation member 12, 13, 14 substantially transparent.

  In this case, in each of the sound insulation members 12, 13, and 14, in the illustrated example, the light transmittance is 70 to 95%, respectively, and the entire sound insulation member 12 and 13 is placed in the overlapping position. A sound insulating member having a light transmittance value set so that the light transmittance is 30 to 60% can be used.

  By providing each of the sound insulating members 12, 13, and 14 with light transmissivity, for example, when the soundproof partition 10 is disposed between the care room and the waiting room, the sound in the waiting room is displayed when the care recipient is sleeping. When the movable sound insulation members 12, 13 are moved to the covering position so that they do not leak into the care room, the care room in the care room is passed through the soundproof partition while the soundproof partition 10 is sound-insulated between the care room and the waiting room. The state of the person can be visually recognized.

  In addition, the light transmittance of each of the sound insulating members 12, 13, 14 can be made lower than the light transmittance of each face material 11. Thereby, since each sound insulation member 12,13,14 can play the role as a blindfold, when the soundproof partition 10 is arrange | positioned between a nursing room and a waiting room, for example, each face material 11 and each sound insulation member The privacy of the non-caregiver can be protected without greatly hindering the visual recognition of the state of the care recipient in the care room through 12, 13, and 14.

  In the example shown in FIGS. 1 to 5, each operation unit 21 is provided on the surfaces 12 d and 13 d located on the side of the face material 11 adjacent to each movable sound insulation member 12 and 13 among the respective surfaces of each movable sound insulation member 12 and 13. Although the example provided is shown, it can replace with or in addition to this, the operation part 21 can be provided in the other surface located on the opposite side to the said surfaces 12d and 13d. In this case, a guide groove 24 for guiding the movement of the operation portion 21 can be formed in the face material 11 located on the other surface side.

  In the example shown in FIGS. 1 to 5, the example in which the soundproof partition 10 includes the three sound insulating members 12, 13, and 14 is shown, but instead of this, the soundproof partition including two sound insulating members or four or more. A soundproof partition provided with a sound insulating member can be applied to the present invention.

  Furthermore, in the example shown in FIGS. 1 to 5, an example in which any one of the sound insulation members 12, 13, and 14 is fixed is shown, but instead, all the sound insulation members 12, 13, and 14 can be moved. can do.

  Moreover, in the example shown in FIGS. 1 to 5, the example in which each face material 11 and each sound insulation member 12, 13, 14 are made of a synthetic resin material is shown. Each of the members 12, 13, and 14 can be formed of a material other than the synthetic resin material such as cloth, glass wool, and wood.

  Furthermore, in the example shown in FIGS. 1 to 5, the example in which each sealing member 26 is made of lead has been shown, but instead of this, a metal other than lead, or an elastic material such as a synthetic resin material or rubber, etc. Thus, the sealing member 26 can be formed of a material other than metal.

  Moreover, in the example shown in FIGS. 1 to 5, an example in which the position of the soundproof partition 10 is fixed is shown, but instead, by providing the soundproof partition 10 with means for moving the soundproof partition 10, The soundproof partition 10 can be used by moving it to a desired position in the room.
