Description

The present invention relates to a partition.

In recent years, it has been practiced to provide a meeting booth for meetings, business negotiations, etc. by dividing the indoor space of an office or the like by a partition. By defining the meeting booth by a partition, the necessary meeting booth can be easily formed, and the indoor space can be used efficiently.

The meeting booth has been downsized from the viewpoint of efficient use of indoor space. However, if the size of the meeting booth is reduced, there is a high possibility that conversations inside the meeting booth will leak out of the meeting booth. From this point of view, a technique has been put into practical use today in which a speaker is provided in the partition and a masking sound is emitted so that the conversation in the meeting booth cannot be heard outside (Japanese Patent Laid-Open No. 2012-82585). See Gazette).

Japanese Unexamined Patent Publication No. 2012-82585

However, when the masking sound is used as described in the above-mentioned publication, there arises a problem that the ambient noise becomes large. In other words, when multiple meeting booths are provided adjacent to each other, the conversation in the meeting booth becomes difficult to hear due to the masking sound for making the conversation in other adjacent meeting booths inaudible, which is relatively large in the meeting booth. It may be necessary to have a voice conversation.

Further, if the masking sound is used as described in the above-mentioned publication, the device may become large-scale. Therefore, it becomes difficult to form or remove a meeting booth as needed, and there is a problem that it is difficult to sufficiently efficiently use the indoor space.

In view of such inconvenience, the present invention provides a partition capable of making it difficult for the conversation content to be transmitted to the outside without increasing the ambient noise and sufficiently achieving the efficient use of the indoor space. The challenge is to provide.

The present invention made to solve the above-mentioned problems includes a plurality of panel members and a support mechanism for supporting the plurality of panel members so as to be able to expand in the left-right direction and overlap in the front-rear direction so as to be overlapped with each other. It is a partition that divides an indoor space in which a sound collecting shape is formed in which sound waves incident from the front are reflected and converged on the front surface of the plurality of panel members in the deployed state of the members.

The plurality of panel members include a central panel member located at the center in the left-right direction in the deployed state, and one or a plurality of pairs of side panel members arranged symmetrically with respect to the central panel member in the deployed state. However, it is preferable that the support mechanism is configured so that each pair of side panel members can be slid to the center side in the left-right direction.

The support mechanism aggregates the side panel members located on the left side of the central panel member in the deployed state on the front left side of the central panel member, and the side panel members located on the right side of the central panel member in the deployed state. It is preferable to concentrate on the front right side of the central panel member.

In the unfolded state, it is preferable to have a gap between adjacent panel members.

It is preferable that the sound collecting shape is a quadratic curved surface of revolution.

In the present invention, "reflecting and converging a sound wave" means that the reflected wave at two or more points on the surface with respect to the sound wave incident from the same point reaches the same point. The "quadratic curve rotating surface" may be a surface approximated by a plurality of planes or spherical surfaces.

The partition according to the present invention is used, for example, to separate a meeting booth from an external space such as an office space. The partition is arranged so that the front surfaces of the plurality of panel members face the meeting booth at the time of use. The partition is supported by the support mechanism so that the plurality of panel members can be expanded in the left-right direction and overlapped in the front-rear direction. Therefore, for example, the plurality of panel members can be aggregated when not in use. , Efficient use of indoor space can be achieved. Further, since the partition has a sound collecting shape that reflects and converges the sound wave incident from the front on the front surface of the plurality of panel members in the deployed state, the meeting is divided by the partition. Even if you talk in a relatively quiet voice in the booth, you can hear each other's voices relatively easily. Therefore, the voice of the speaker is naturally reduced, and it is possible to prevent the voice from leaking to the outside and being heard by a third party.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings as appropriate.

[Partition]
The partition shown in FIGS. 1 to 6 divides an indoor space. The partition is not a permanent partition provided, for example, connected to the ceiling or floor of a building, but a temporary partition formed separately from the building. The partition has a plurality of panel members 1a to 1c. Further, the partition includes a support mechanism 3 capable of deploying a plurality of panel members 1a to 1c in the left-right direction and overlapping them in the front-rear direction (the support mechanism 3 is shown only in FIGS. 1 and 2). (Fig. 3 to FIG. 6 are not shown). Further, the partition may be provided with a moving mechanism for facilitating the movement of a plurality of panel members 1a to 1c in an integrated state, for example. Examples of the moving mechanism include casters arranged at the lower end of the support mechanism 3.

As shown in FIGS. 1 to 3, the partition has a sound collecting shape 2 that reflects and converges sound waves incident on the front surface of the plurality of panel members 1a to 1c in the deployed state of the plurality of panel members 1a to 1c. Is formed. In addition, in this invention, "before" means the side which suppresses leakage of the conversation content to the outside by the partition which concerns on this invention, and in this embodiment, it means the meeting booth side. Also, "rear" means the opposite side of "front". Further, the "left-right direction" means a horizontal direction perpendicular to the front-back direction.

(Panel member)
The plurality of panel members 1a to 1c are each formed in a plate shape, and the plate thickness direction is arranged in the front-rear direction. Each of the plurality of panel members 1a to 1c is formed in a rectangular shape in the front view, and more specifically, is formed in a rectangular shape having a length in the vertical direction longer than the length in the horizontal direction. The plurality of panel members 1a to 1c are arranged symmetrically with respect to the central panel member 1a located in the center in the left-right direction in the deployed state and the central panel member 1a in the deployed state (2 in the present embodiment). It has a pair of side panel members 1b and 1c. That is, the partition has an odd number of panel members 1a to 1c. The "plate shape" means a shape having a large width and height with respect to the thickness.

The lengths of the plurality of panel members 1a to 1c in the vertical direction are substantially the same. Further, the left-right length of each side panel member 1b, 1c is shorter than the left-right length of the central panel member 1a. The upper limit of the ratio of the left-right lengths of the side panel members 1b and 1c to the left-right length of the central panel member 1a is preferably 0.5. When the above ratio exceeds the above upper limit, when the side panels 1b and 1c are aggregated in front of the center panel 1a as described later, the left and right outer ends of the side panels 1b and 1c are left and right of the center panel member 1a. It may protrude outward from the direction end portion, resulting in insufficient handleability in the integrated state of the plurality of panel members 1a to 1c. The lengths of the side panel members 1b and 1c in the left-right direction may be different, but they are preferably equal in terms of handleability in an integrated state and uniform sound wave collecting function.

The plurality of panel members 1a to 1c have a sound collecting portion on the front surface. In the partition, a sound collecting shape is formed in the sound collecting portion in the expanded state of the plurality of panel members 1a to 1c. Further, in the present embodiment, the entire front surface of the plurality of panel members 1a to 1c is configured as a sound collecting portion.

The sound collecting shape 2 is preferably a quadratic curved surface of revolution. That is, it is preferable that the partition includes the sound collecting portions of the plurality of panel members 1a to 1c in one quadratic curve rotating surface in the expanded state of the plurality of panel members 1a to 1c. When the sound collecting shape 2 is a quadratic curve rotating surface, the partition is arranged so that, for example, the rotation axis of the quadratic curve rotating surface passes near the heads of two speakers facing each other in the meeting booth. Therefore, it is easy to reflect the voice of the speaker on the side distant from the sound collecting shape 2 and converge it in the vicinity of the speaker located on the sound collecting shape 2 side. In particular, on the sound collecting shape 2 side, by adjusting the head of one speaker located with the back to the sound collecting shape 2 so as to be close to the focal position of the sound collecting shape 2, the other speaker The voice can be reflected by the sound collecting shape 2 and can be surely converged near the head of one speaker. As a result, it becomes easier for one speaker who is positioned with his back to the sound collecting shape 2 to hear the conversation of the other speaker. The broken line shown for each panel member 1a to 1c in FIG. 2 indicates the horizontal position of the front surface of each panel member 1a to 1c through the rotation axis of the quadratic curve rotating surface constituting the sound collecting shape 2. Shows.

Further, when the sound collecting shape 2 is a quadratic curve rotating surface, it is preferable that the rotation axis of the quadratic curve rotating surface is located at the central portion in the left-right direction of the central panel member 1a. In this way, when the rotation axis of the quadratic curve rotation surface is located at the center of the central panel member 1a in the left-right direction, a pair of side panels adjacent to the left and right of the center panel member 1a at any position in the vertical direction. The front surface of the sound collecting portion of the member 1b is located in front of the front surface of the sound collecting portion of the central panel member 1a, and the other pair of side panel members 1c adjacent to the outer side in the left-right direction of the pair of side panel members 1b. The front surface of the sound collecting portion is located in front of the front surface of the sound collecting portion of the pair of side panel members 1b. Therefore, as will be described later, by sliding each pair of side panel members 1b and 1c in the left-right direction, it is easy to gather these side panel members 1b and 1c in front of the central panel member 1a. Further, by locating the rotation axis of the quadratic curve rotation surface at the central portion in the left-right direction of the central panel member 1a, the sound collecting shapes 2 of the side panel members 1b and 1c of each pair can be formed symmetrically. Therefore, it is easy to provide the support mechanism 3 in a relatively simple configuration. The rotation axis of the quadratic curve rotation surface is preferably located at the center of the sound collecting portion in the vertical direction. As described above, by locating the rotation axis of the quadratic curve rotating surface at the central portion in the vertical direction of the sound collecting portion, it is easy to enhance the sound collecting effect.

When the sound collecting shape 2 is a quadratic curved surface of revolution, it is preferable that the rear surface of each side panel member 1b, 1c is provided so that the inner end portion in the left-right direction is located most rearward. In this case, the thickness of each side panel member 1b, 1c may be gradually increased from the inside to the outside in the left-right direction, or may be substantially uniform in the entire region in the left-right direction. According to this configuration, for example, by making the thickness of the inner end portion in the left-right direction of each side panel member 1b, 1c relatively small, the rear surface of the pair of side panel members 1b adjacent to the left and right of the center panel member 1a can be formed. The rear surface of the other pair of side panel members 1c located in front of the front surface of the central panel member 1a and adjacent to the lateral side of the pair of side panel members 1b in the left-right direction is the front surface of the pair of side panel members 1b. It is easy to arrange it so that it is located in front of it. That is, when the panel members 1a to 1c are continuously provided without sandwiching a gap in the left-right direction, the rearmost surfaces of the pair of side panel members 1b adjacent to the left and right of the center panel member 1a are the side panels. The other side panel member located behind the front surface of the central panel member 1a by the thickness of the left-right inner end portion of the member 1b and adjacent to the left-right outer side of the pair of side panel members 1b. The rear surface of 1c is located behind the front surface of the pair of side panel members 1b by the thickness of the left-right inner end portion of these side panel members 1c. Therefore, the rear surface of the left-right inner end portion of the pair of side panel members 1b adjacent to the left and right of the central panel member 1a is located in front of the front surface of the left-right outer end portion of the central panel member 1a, and the pair of sides. Each panel so that the rear surface of the left-right inner end portion of the other pair of side panel members 1c adjacent to the left-right outer side of the one-side panel member 1b is located in front of the left-right outer front surface of the pair of side panel members 1b. By providing a gap between the members 1a to 1c, as will be described later, each pair of side panel members 1b, 1c can be slid inward in the left-right direction, and these side panel members 1b, 1c can be moved to the center panel. It is easy to gather in front of the member 1a. Further, according to this configuration, the panel members 1a to 1c having similar shapes can be stacked in order in the front-rear direction, so that it is easy to save space in the integrated state.

The partition preferably has a gap between adjacent panel members 1a to 1c in the unfolded state. In other words, it is preferable that the partition is divided by a slit extending in the vertical direction from a plurality of panel members 1a to 1c in a front view in a deployed state. Specifically, the partition is a panel member 1b, which is adjacent to the outer side of the panel members 1a, 1b in the left-right direction from the front surface of the panel members 1a, 1b located inward in the left-right direction at any position in the vertical direction. It is preferable to have a gap between the adjacent panel members 1a to 1c so that the rear surface of 1c is located forward. According to this configuration, as described above, by sliding each pair of side panel members 1b, 1c inward in the left-right direction, it is easy to gather these side panel members 1b, 1c in front of the center panel member 1a. .. If there is a gap between the adjacent panel members 1a to 1c in the unfolded state, the reflection ratio of the sound wave due to the sound collecting shape 2 decreases, but the partition is assumed to be the sound collecting portion of the plurality of panel members 1a to 1c. Even if the length in the left-right direction and the distance in the left-right direction of the gap are about the same, the decrease in sound gain can be suppressed to about 3 dB. On the other hand, when the sound collecting shape 2 is the above-mentioned quadratic curved surface of revolution, the reflected sound tends to be a sound in which the high frequency range is emphasized. The sound can be effectively escaped from this gap, and the sound quality in which the high frequency range is emphasized can be improved.

The quadratic curve surface of revolution is preferably a spheroidal surface. Since the spheroidal surface of revolution is a spheroidal surface, the two focal points of the surface of revolution of the quadratic curve are adjusted to the vicinity of the assumed heads of two speakers, so that the surface of revolution is separated from the sound collecting shape 2. The voice of the speaker can be reflected and easily and surely converged in the vicinity of the speaker located on the sound collecting shape 2 side.

Further, the quadratic curve rotating surface may be a rotating paraboloid. Since the quadratic curve rotating surface is a rotating paraboloid, for example, when a plurality of speakers are adjacent to each other in the left-right direction facing the sound collecting shape 2, the voices of the plurality of speakers are efficiently heard. Can be converged.

(Support mechanism)
The support mechanism 3 rails the rail members 3a arranged on the upper and lower ends of the upper ends and the lower ends of the side panel members 1b and 1c of each pair, and the upper ends and the lower ends of the side panel members 1b and 1c of each pair. It has a connecting member 3b that is slidably engaged with the member 3a. Further, the support mechanism 3 is arranged below the rail members 3a arranged above the upper ends of the side panel members 1b and 1c of each pair and below the lower ends of the side panel members 1b and 1c of each pair. It has a frame 3c that holds the rail member 3a in the vertical direction and the horizontal direction at regular intervals. Although not shown, the support mechanism 3 further has a holding member for holding the central panel member 1a at a predetermined position with respect to the rail member 3a.

The rail member 3a extends in the left-right direction. The rail member 3a is configured so that each pair of side panel members 1b and 1c can slide in the extending direction. The support mechanism 3 has a plurality of rail members 3a. Each rail member 3a is connected to the left-right inner end portion or the left-right outer end portion of the paired side panel members 1b, 1c by the connecting member 3b. Therefore, a pair of rail members 3a corresponding to each pair of side panel members 1b and 1c are provided, and in this embodiment, two pairs of rail members 3a are provided.

The specific configuration of the connecting member 3b is not particularly limited as long as each pair of side panel members 1b and 1c can be slidably engaged in the extending direction of the rail member 3a. In the present embodiment, the connecting member 3b that connects the upper ends of the side panel members 1b and 1c of each pair and the rail member 3a has a hook mounting portion that is slidably attached to the rail member 3a and each pair of side panels. It has a hook attached to the upper ends of the members 3b and 3c and locked to the hook attachment portion. Further, the connecting member 3b that connects the lower ends of the side panel members 1b and 1c of each pair and the rail member 3a is attached to the lower ends of the side panel members 1b and 1c of each pair and is attached to the upper surface of the rail member 3a. It has casters that are movably fitted in the extending direction of the rail member 3a.

It is preferable that the support mechanism 3 is configured so that each pair of side panel members 1b and 1c can be slidable toward the center in the left-right direction. As described above, the partition consists of a central panel member 1a located in the center in the left-right direction in the unfolded state and two pairs of side panel members 1b, 1c arranged symmetrically with respect to the central panel member 1a in the unfolded state. And have. As described above, in the partition, the rear surface of the left-right inner end portion of the pair of side panel members 1b is located in front of the front surface of the left-right outer end portion of the central panel member 1a, and the other pair is lateral. By providing a gap between the panel members 1a to 1c so that the rear surface of the left-right inner end portion of the panel member 1c is located in front of the front surface of the left-right outer end portion of the pair of side panel members 1b, respectively. The pair of side panel members 1b and 1c can be slid toward the center in the left-right direction. The partition is configured such that the support mechanism 3 slides each pair of side panel members 1b and 1c toward the center side in the left-right direction, and as shown in FIGS. 4 to 6, these side panel members 1b , 1c can be easily stacked in front of the central panel member 1a, and the length in the left-right direction in the aggregated state can be shortened to improve the handleability in the aggregated state.

Further, as shown in FIGS. 4 to 6, the support mechanism 3 gathers the side panel members 1b and 1c located on the left side of the central panel member 1a in the unfolded state on the front left side of the central panel member 1a and is in the unfolded state. It is preferable to consolidate the side panel members 1b and 1c located on the right side of the central panel member 1a on the front right side of the central panel member 1a. According to this configuration, it is easy to make the outline shape of the plurality of panel members 1a to 1c into a rectangular shape in a plan view in the aggregated state, that is, it is easy to match the outer ends of the panel members 1a to 1c in the left-right direction in the front view in the aggregated state. It is possible to improve the handleability in the aggregated state.

<Advantage>
The partition is arranged so that the front surfaces of the plurality of panel members 1a to 1c face the meeting booth at the time of use. Since the partition is supported by the support mechanism 3 so that the plurality of panel members 1a to 1c can be expanded in the left-right direction and overlapped in the front-rear direction, for example, the plurality of panel members 1a to 1c can be aggregated when not in use. By doing so, it is possible to efficiently use the indoor space. Further, when the partition is provided with the above-mentioned moving mechanism for facilitating the movement of the plurality of panel members 1a to 1c in the aggregated state, the partition is moved to a storage space or the like separately provided in the aggregated state when not in use. Occasionally, the panel members 1a to 1c can be expanded and used after being moved to the place of use. Further, in the partition, a sound collecting shape 2 is formed in which sound waves incident from the front are reflected and converged on the front surface of the panel members 1a to 1c in the deployed state of the plurality of panel members 1a to 1c. Even when talking in a relatively quiet voice in a meeting booth divided by partitions, it is possible to hear each other's voices relatively easily. Therefore, the voice of the speaker is naturally reduced, and it is possible to prevent the voice from leaking to the outside and being heard by a third party.

[Other embodiments]
The embodiments do not limit the configuration of the present invention. Accordingly, the embodiments may be omitted, replaced or added to components of each of the embodiments based on the description of the present specification and common general knowledge, all of which are construed as belonging to the scope of the present invention. Should be.

For example, the partition may have only a pair of side panel members in which the plurality of panel members are arranged symmetrically with respect to the central panel member and the central panel member in a deployed state. Further, the partition does not necessarily have to have a central panel member, and may have, for example, only a plurality of pairs of side panel members arranged symmetrically in the left-right direction.

As long as the partition can be aggregated so that a plurality of panel members are overlapped in the front-rear direction, the specific aggregation structure of the plurality of panel members is not limited.

The support mechanism may be configured to be movable in the front-rear direction by adding each pair of side panel members in the left-right direction. As a configuration in which each pair of side panel members can be moved in the left-right direction and the front-back direction, for example, as shown in FIG. 7, at the left-right inner end portion or the left-right outer end portion of each side panel member 11b, 11c. It is possible to adopt a configuration in which a plurality of rail members 13a corresponding to each are provided, and each of these rail members 13a has a main portion extending in the left-right direction and a sub portion extending in the front-rear direction. In this way, the support mechanism is configured to add each pair of side panel members in the left-right direction and move in the front-rear direction as well, so that, as shown in FIG. 8, for example, each pair of side panel members 11b, The 11c can be aggregated so as to be in contact with or close to the front surface of the central panel member 11a, and the handleability in the aggregated state can be further improved. Further, as a configuration in which each pair of side panel members can be moved in the left-right direction and the front-rear direction, for example, as shown in FIGS. 9 and 10, the rail member 23a can be brought close to the rail member 23a in the front-rear direction by the articulated frame 23c. It is also possible to adopt a configuration that does.

In the above-described embodiment, the configuration in which the sound collecting shape is one quadratic curve rotating surface has been described, but the sound collecting shape is not particularly limited as long as the reflected sound wave can be converged. For example, it may be a combination of a plurality of quadratic curve rotating surfaces.

It is also possible to adopt a structure in which the partition does not have a gap between adjacent panel members in the deployed state. As a configuration having no gap between adjacent panel members in the deployed state, for example, a configuration in which an elastic member that does not restrict the slide in the left-right direction is arranged on the side surface of each panel member can be mentioned.

As described above, the partition of the present invention can make it difficult for the conversation content to be transmitted to the outside without increasing the ambient noise, and can sufficiently achieve the efficient use of the indoor space. It can be particularly suitably used for dividing the indoor space to form a meeting booth.
