[0005] [Patent Document 1] JP 2014-88745 A (page 5, Figure 2) Summary of the Invention [Problem to be solved by the invention]

[0006] The partition panel device described in Patent Document 1 employs a pair of glass panels, which not only provides high visibility and aesthetic appeal, but also offers excellent thermal insulation due to the air layer in the inter-panel space between the front and rear glass panels. However, when sound generated on one side of the partition panel device causes one glass panel to vibrate, the vibration vibrates the air in the inter-panel space, which in turn vibrates the other glass panel, potentially transmitting the sound to the other side. One approach to preventing such sound leakage is to place various soundproofing materials, such as glass wool, in the inter-panel space. However, this approach has the drawback of reducing visibility and impairing aesthetic appeal, thereby negating the advantages of glass panels.

[0007] The present invention has been made in view of these problems, and has as its object to provide a partition panel device with improved soundproofing performance. [Means for solving the problem]

And, The enclosed space is formed in plurality by partitioning members inside the panel support body. It is characterized by the presence of According to this feature, even if sound generated outside at least one of the glass panels vibrates the air in the space between the panels through the other glass panel, the enclosed space that functions as a Helmholtz resonator can absorb the sound in the corresponding frequency band, thereby improving soundproofing performance without damaging the aesthetic appearance.

[0009] The panel support body is characterized in that a plurality of the closed spaces are formed inside the panel support body by being partitioned by partition members. According to this feature, sound can be appropriately absorbed at a plurality of locations by the enclosed spaces and the openings.

According to this feature, it is possible to provide a partition panel that has an inconspicuously thin vertical frame, secures a wide glass surface in the left-right direction, and has excellent aesthetics and sufficient soundproofing effect.

[0011] One of the panel supports is a lower panel support that is fixed to the floor surface. This feature makes it possible to absorb noise from the floor side, which is closer to users and where there is a lot of work.

[0012] The plurality of closed spaces are characterized by being provided in a left-right direction. This feature allows the sound absorption of small sounds occurring in either the left or right direction.

[0013] The plurality of closed spaces are characterized by being provided in a front-rear direction. According to this feature, sound transmitted from one side of the pair of glass panels to the other side can be absorbed in multiple stages.

[0014] The opening is provided in the center of the enclosed space. According to this feature, the closed space that functions as a Helmholtz resonator can efficiently exert the sound absorption effect of sounds in the frequency band. [Brief explanation of the drawings]

[Figure 4] FIG. 2 is an exploded perspective view showing an enlarged view of a main part of the partition panel device. [Figure 5] FIG. 2 is an enlarged plan view of a main part of the partition panel device. DETAILED DESCRIPTION OF THE INVENTION

[0016] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A partition panel device according to the present invention will be described below with reference to the following embodiments. [Example]

[0017] A partition panel device according to an embodiment will be described with reference to Figures 1 to 5. In the following description, the left side of the screen in Figure 3 will be the front side (front side) of the partition panel device, and the right side of the screen in Figure 3 will be the back side (rear side) of the partition panel device.

[0018] The partition panel device 1 is made up of multiple panels attached from the ceiling to the floor in order to divide and partition a room or space in a building, such as a school or office, into multiple sections.Transparent glass panels 4 (panel bodies) are used to create an open feeling in the partitioned space, and the device has excellent strength and sound insulation properties.

[0019] 1 and 2, the partition panel device 1 in this embodiment has a double glass panel structure in which a plurality of glass panels 4, 4, ... are attached spaced apart from each other in the front and rear between an upper panel support member 2 fixed to the ceiling R and a lower panel support member 3 fixed to the floor surface F. Furthermore, a left side panel support member 5 and a right side panel support member 6 are provided at the left and right ends of the pair of front and rear glass panels 4, 4 located on both the left and right ends, respectively, to close off an intra-panel space S1 (see FIG. 3) between the pair of front and rear glass panels 4, 4, ...

[0020] In this embodiment, the left side panel support body 5 is fixed not only to the upper panel support body 2 and the lower panel support body 3 but also to the wall surface W, but this is not limited to this and it may be supported only by the upper panel support body 2 and the lower panel support body 3, like the right side panel support body 6, and may be modified as appropriate as long as it has a configuration that can close off the intra-panel space S1. The same is true for the right side panel support body 6, which is supported by the upper panel support body 2 and the lower panel support body 3, but this is not limited to this and it may be fixed not only to the upper panel support body 2 and the lower panel support body 3 but also to the wall surface W, like the left side panel support body 5.

[0021] In addition, since the glass panels 4, 4 mounted spaced apart at the front and rear have the same configuration, we will only explain the glass panel 4 mounted on the front side of the partition panel device 1, and will omit an explanation of the glass panel 4 mounted on the rear side. This also applies to the explanation of the glass panel 4 being supported upright by the upper panel support body 2, lower panel support body 3, left side panel support body 5, and right side panel support body 6.

[0022] The opposing ends of adjacent glass panels 4, 4, ... on the left and right are filled with a highly transparent resin joint material (not shown), making it possible to connect them in the left and right direction without using frames in the up and down direction.

[0023] 2 and 3, each glass panel 4 is a laminated glass made by strengthening two transparent glass plates by laminating them together. Note that the glass panel 4 is not limited to glass plates, and may be made of, for example, a transparent acrylic plate material.

[0024] Next, a detailed description will be given of the lower panel support body 3. As shown in Figures 2 to 4, the lower panel support body 3 is mainly composed of a baseboard 30, a lower support member 31, a plate member 32, a partition member 33, and a cover 10b.

[0025] As shown in FIGS. 2 and 4, the baseboard 30 is formed by extrusion molding of an aluminum alloy into an upward U-shape when viewed from the side.

[0026] The baseboard 30 is fixed to the floor surface F by anchor bolts (not shown) together with a plurality of support brackets 37, 37, ... stacked vertically on its bottom plate 30a. The number of stacked support brackets 37 can be changed as needed. This makes it possible to adjust the height of the lower support member 31 placed on the support brackets 37.

[0027] The lower support member 31 is formed by extrusion molding of an aluminum alloy so as to be M-shaped when viewed from the side.

[0028] The lower support member 31 is composed of a base 31a that is fitted over the baseboard 30 so as to cover it from above, and front and rear support parts 31b, 31b that are respectively arranged on the outer surfaces of the front and rear side panels 30b, 30b of the baseboard 30. Since the front and rear support parts 31b, 31b have the same structure, only the structure of the front support part 31b will be described, and a description of the structure of the rear support part 31b will be omitted.

[0029] The base 31a includes front and rear side panels 311 extending along the front and rear side panels 30b of the baseboard 30, front and rear top panels 312 extending toward the center in the front-to-rear direction, generally perpendicular to the upper ends of the side panels 311, front and rear side walls 313 extending downward from the center of the front and rear top panels 312, a bottom panel 314 extending generally perpendicular to the lower sides of the front and rear side walls 313, and front and rear legs 315 formed at the lower ends of the front and rear side walls 313. The side walls 313 and bottom panel 314 form a groove shape that opens upward.

[0030] Referring to the front side wall 313, the side wall 313 has an upper plate 313a that extends downward in a straight line approximately perpendicular to the front top plate 312, an inclined plate 313b that slopes toward the center from the lower end of the upper plate 313a and extends downward in a straight line, and a lower plate 313c that extends downward in a straight line approximately parallel to the upper plate 313a from the lower end of the inclined plate 313b.

[0031] The lower support member 31 has front and rear legs 315 placed on the uppermost support fittings 37 with the front and rear side plates 311, 311 fitted onto the front and rear side plates 30b, 30b of the baseboard 30.

[0032] The front support portion 31b extending from the front side plate 311 has a flat upper end surface on which the glass panel 4 is placed. With the glass panel 4 placed, the cover 10b is engaged with the front support portion 31b, thereby enabling the glass panel 4 to be supported in an upright position.

[0033] As shown in FIGS. 2 and 4, the plate member 32 is formed by extrusion molding of an aluminum alloy into a Π shape in a side view.

[0034] The plate member 32 has a flat plate-like portion 320 having a plurality of through holes 32a formed therein that penetrate in the thickness direction, i.e., in the vertical direction, front and rear legs 321, 321 formed on the lower side of the front and rear ends of the plate-like portion 320, and front and rear locking pieces 322, 322 that protrude downward from the center of the left-right direction at the lower end of the plate-like portion 320.

[0035] More specifically, the through holes 32a are two through holes 32a, 32a that are spaced apart in the front-rear direction at the center of the plate-shaped portion 320. Furthermore, these two through holes 32a, 32a are formed at a predetermined interval in the left-right direction of the plate-shaped portion 320.

[0036] The plate member 32 is assembled to the lower support member 31 by placing the front and rear legs 321, 321 on the front and rear top plates 312, 312 of the lower support member 31, so that the front and rear locking pieces 322, 322 are locked to the front and rear top plates 312, 312 of the lower support member 31. As a result, the lower support member 31 and the plate member 32 form a support internal space S2.

[0037] Furthermore, the support internal space S2 is partitioned by dividers 33 into compartments S3, which are multiple closed spaces. Here, the closed space refers to a space that is surrounded by the lower support member 31, the plate member 32, and the dividers 33 and functions as a Helmholtz resonator. As will be described later, the space does not strictly need to be sealed as long as it functions as a Helmholtz resonator. In other words, the support internal space S2 is formed by being surrounded by the lower support member 31 and the plate member 32. Even if there are gaps between the dividers 33 that separate the support internal space S2 and between the dividers 33 and the lower support member 31 and the plate member 32, and adjacent compartments S3, S3 are connected to each other, there is little air flow within the spaces between the compartments S3, S3. Therefore, the compartment S3 functions as a container surrounded by the lower support member 31, the plate member 32, and the dividers 33, i.e., it can be a closed space that functions as a Helmholtz resonator.

[0038] As shown in Figure 4, the partition 33 is composed of a plate-shaped bottom plate 330, a longitudinal partition plate 331 supported upright on the bottom plate 330, and a lateral partition plate 332 supported by the bottom plate 330 and the longitudinal partition plate 331.

[0039] The bottom plate 330 is formed by die-cutting and molding resin, and extends in the longitudinal direction, i.e., the left-right direction, along the bottom plate 314 of the lower support member 31. The width of the bottom plate 330, i.e., the dimension in the front-to-rear direction, is approximately the same as the dimension between the lower plates 313c, 313c of the lower support member 31. This allows the bottom plate 330 to be stably placed on the bottom plate 314.

[0040] In addition, long holes 330a that penetrate vertically and are elongated in the left-right direction at the center in the front-rear direction are formed at predetermined intervals in the bottom plate 330. Furthermore, slits 330b that penetrate vertically and are open to the front or rear side are formed at predetermined intervals in the bottom plate 330.

[0041] The longitudinal partition plate 331 is formed by die-cutting molding of resin, and extends in the longitudinal direction, i.e., the left-right direction, along the bottom plate 314 of the lower support member 31. The height of the longitudinal partition plate 331, i.e., the vertical dimension, is approximately the same as the vertical dimension of the support body internal space S2.

[0042] The longitudinal partition plate 331 has a locking piece 331a formed at its lower end so as to protrude downward, and the locking piece 331 is inserted into a long hole 330a of the bottom plate 330 so as to be erected.

[0043] Further, the longitudinal partition plate 331 is formed with slits 331b at predetermined intervals, which penetrate in the front-rear direction and are open upward.

[0044] The short-side partition plate 332 is formed into a downward U-shape by die-cutting resin. The width dimension of the short-side partition plate 332 is approximately the same as the dimension between the lower plates 313c, 313c of the lower support member 31. The height dimension of the short-side partition plate 332 is approximately the same as the vertical dimension of the support body internal space S2. Here, the bottom plate 330, the long-side partition plate 331, and the short-side partition plate 332 may be formed from a material other than resin.

[0045] A slit 332a that penetrates in the left-right direction and is open downward is formed in the short-side partition plate 332. In addition, the short-side partition plate 332 is formed with locking pieces 332b that protrude downward at the front and rear lower ends thereof.

[0046] To assemble these, first, the longitudinal partition plate 331 is erected on the bottom plate 330, and then, The short-side partition plate 332 is inserted perpendicularly to the long-side partition plate 331; specifically, they are engaged through the respective slits 331b, 332a, and the front and rear locking pieces 322b are inserted into the front and rear slits 330b in the bottom plate 330. In this manner, the partition device 33 is composed of the plate-shaped bottom plate 330 and long-side partition plate 331 arranged along the longitudinal direction of the lower support member 31, and the short-side partition plate 332 arranged along the short direction of the lower support member 31, and can be made to stand on its own by itself. Furthermore, since the partition device 33 is separate from the lower support member 31, multiple compartments S3, which are closed spaces, can be formed simply by placing the partition device 33 on the bottom plate 314 of the lower support member 31. This simplifies the structure and also makes it easy to change the compartments of the compartments S3.

[0047] In this way, the support body internal space S2 is divided into approximately equal parts in the front-rear direction by the longitudinal partition plates 331, and further divided into approximately equal parts in the left-right direction by the lateral partition plates 332, forming a plurality of compartments S3 that are closed spaces. These compartments S3 are arranged approximately equally in both the front-rear and left-right directions. As shown in Figure 3, a gap G is generated between the lateral partition plates 332 that form the compartments S3 and the side walls 313 of the lower support member 31, so that adjacent compartments S3, S3 on the left and right are in communication with each other. In this way, even if adjacent compartments S3, S3 are connected to each other, the air in the space between the compartments S3, S3 does not flow very much, and as shown in Figures 4 and 5, the position near the short-side partition plate 332 where the gap G is formed is far from the through hole 32a, so there is little impact on the compartment S3 functioning as a container surrounded by the lower support member 31, the plate member 32 and the partition 33, and the compartment S3 can become a closed space that functions sufficiently as a Helmholtz resonator.

[0048] 5, the through hole 32a of the plate member 32 is disposed approximately in the center in the front-rear direction between the longitudinal partition plate 331 and the lower plates 313c, 313c of the lower support member 31, and approximately in the center in the left-right direction between a pair of adjacent lateral partition plates 332, 332. In this way, the opening of the through hole 32a is provided in the center of the plate member 32 of each compartment S3, which is an enclosed space, so that the sound absorption effect of the Helmholtz resonator on sound in the frequency band can be efficiently exerted.

[0049] Next, we will explain the upper panel support body 2. As shown in Fig. 2, the upper panel support body 2 is mainly composed of a coping board 20, an upper support member 21, a plate member 22, and a cover 10b.

[0050] The head board 20 has a downward U-shape when viewed from the side, and is fixed to the ceiling R with multiple bolts (not shown). Multiple hanging brackets 27 are fastened to the inside of the head board 20 by bolts. An upper support member 21 is suspended from each hanging bracket using an adjuster bolt for height adjustment. A plate member 22 is engaged with the upper support member 21.

[0051] With the glass panel 4 disposed below the support portion 21b of the upper support member 21, the cover 10b is engaged with the support portion 21b, thereby supporting the glass panel 4 in an upright position.

[0052] Next, the left side panel support member 5 and the right side panel support member 6 will be described.

[0053] 1, pillar 50 of left side panel support body 5 is fixed to wall surface W, and its upper end is connected to upper panel support body 2 by a connecting metal fitting (not shown), and its lower end is connected to lower panel support body 3 by a connecting metal fitting (not shown). With the left end of glass panel 4 placed on a support portion (not shown) of pillar 50, cover 10a is engaged with the support portion, thereby supporting glass panel 4 in an upright position.

[0054] Similar to the left side panel support body 5, the pillar body 60 of the right side panel support body 6 has its upper end connected to the upper panel support body 2 and its lower end connected to the lower panel support body 3 by connecting metal fittings. With the right end of the glass panel 4 placed on a support part (not shown) of the pillar body 60, the cover 10a is engaged with the support part, thereby supporting the glass panel 4 in an upright position.

[0055] Although not shown directly, the pillar 60 is connected to an upper panel support 2 and a lower panel support 3 extending rearward in the drawing, and glass panels 4, 4 spaced apart in the left-right direction.

[0056] Here, we will explain the sound absorption performance that applies Heltzholm resonance. We will explain a Heltzholm resonator that uses multiple compartments S3, which are closed spaces partitioned in the lower panel support body 3. However, similar Heltzholm resonators that use multiple compartments S3, which are closed spaces partitioned, can also be formed in the upper panel support body 2, the left side panel support body 5, and the right side panel support body 6. In particular, a Heltzholm resonator that uses multiple compartments S3, which are closed spaces partitioned in the lower panel support body 3, can absorb sounds from the floor side, which is close to users and where there is a lot of work, such as sounds from walking and sounds from moving carts, thereby improving the sound absorption effect for users.

[0057] A Helmholtz resonator is a device in which the air inside a container with an opening acts as a spring, and the air inside the container resonates, absorbing sound energy around the resonating frequency. The resonant frequency (natural frequency) (f) of a Helmholtz resonator is determined by the internal volume of the container (V), the area of ​​the opening (S), the neck length of the opening (L), and other factors, and is expressed by the following formula: f=(c / 2π)√(S / VL)

[0058] In the embodiment, the plate member 32 that forms the support internal space S2 is provided with a plurality of through-holes 32a that penetrate in the thickness direction, i.e., the vertical direction, as described above, and in the plurality of compartments S3 that are partitioned closed spaces in the lower panel support member 3, the area of ​​the through-hole 32a in each compartment S3 (if the compartment S3 has a plurality of through-holes 32a, the sum of the areas of the through-holes 32a) is the "area of ​​the opening (S)," the thickness of the plate member 32 is the "neck length (L) of the opening," and the volume of each compartment S3 is the "internal volume (V) of the container." By appropriately selecting the area of ​​the through-holes 32a, the thickness of the plate member 32, and the volume of the closed chamber S3, sound energy in a desired frequency band (e.g., 500 Hz) can be absorbed in each compartment S3, thereby improving soundproofing performance.

[0059] According to these embodiments, even if sound generated outside one of the glass panels vibrates the air in the space between the panels through that glass panel, the Helmholtz resonator can absorb the sound in the corresponding frequency band, thereby improving the sound absorption effect and soundproofing performance without damaging the aesthetic appearance.

[0060] Furthermore, if a plurality of partitioned chambers S3, which are partitioned closed spaces, are provided in the left and right direction, even small sounds generated anywhere in the left and right direction can be absorbed.

[0061] Furthermore, if multiple partitioned chambers S3, which are partitioned closed spaces, are provided in the front-to-back direction, sound transmitted from one side of a pair of glass panels to the other can be absorbed in multiple stages.

[0062] Furthermore, if the multiple compartments S3, which are partitioned closed spaces, have approximately the same volume and the sum of the opening areas of the through holes 32a communicating with one of the multiple compartments S3 is approximately the same, the frequency band that can be absorbed in each compartment S3, which is a closed space that functions as a Helmholtz resonator, can be made approximately constant, thereby improving sound absorption efficiency.

[0063] Furthermore, one of the plurality of compartments S3 may be connected to one of the through holes 32a, which reduces the number of steps required to process the through holes 32a.

[0064] In the embodiment, the through-holes 32a are through-holes formed in the plate member 32 that separate the support body internal space S2, which includes a plurality of compartments S3 that are partitioned closed spaces, from the inter-panel space S1, and the plate member 32 can function as a diaphragm. That is, by making the plate member 32 function as a diaphragm, it is possible to resonate with the sound transmitted from one side of the glass panel to the other, thereby further enhancing the soundproofing effect. To make the plate member 32 function as a diaphragm, it is preferable that the lower surface of the plate member 32 is slightly spaced from the partitions 33, specifically the longitudinal partitions 331 and the lateral partitions 332.

[0065] Although the embodiments of the present invention have been described above with reference to the drawings, the specific configuration is not limited to these embodiments, and the present invention also includes modifications and additions that do not deviate from the gist of the present invention.

[0066] For example, in the embodiment, the Helmholtz resonator is provided on the lower panel support 3, but it may be provided on any of the upper panel support 2, left side panel support 5, or right side panel support 6, or on more than one or all of these panel support members.

[0067] Furthermore, in the embodiment, the Helmholtz resonator has been described as one in which the volumes of the multiple compartments S3 are approximately the same and sound energy in a specific frequency band is absorbed, but the volumes (V) of the multiple compartments S3 or the opening areas (S) of the through holes 32a may be different to absorb sound energy in multiple frequency bands.

[0068] In addition, in the embodiment, the panel support body that supports the glass panel has been described as being supported by an upper panel support body 2, a lower panel support body 3, a left side panel support body 5, and a right side panel support body 6 that surround the glass panel on all four sides, but the support body may support the glass panel on two sides, such as top and bottom, or on three sides, such as top and left and right, or bottom and left and right.

[0069] In addition, in the embodiment, the multiple partitioned chambers S3, which are partitioned closed spaces in the lower panel support body 3, are described as consisting of multiple chambers in the front and back and multiple chambers on the left and right, but the multiple partitioned chambers S3 may also consist of one chamber in the front and back (multiple chambers on the left and right) or one chamber in the front and back (multiple chambers on the front and back).

[0070] In addition, in the embodiment, the partition 33 is described as being separate from the lower support member 31, but the partition 33 does not have to be separate from the lower panel support member 31 or the plate member 32; instead, the partition 33 may be formed of a partition plate on the lower panel support member 31 or the plate member 32.

[0071] In the embodiment, the "neck length (L) of the opening" related to the value of the resonant frequency (natural frequency) (f) of the "Helmholtz resonator" of the compartment S3, which is a closed space, has been described as the "thickness of the plate member 32." However, this is not limited thereto. A cylindrical portion extending vertically from the through-hole 32a may be provided, and the "neck length (L) of the opening" may be defined as "the thickness of the plate member 32 + the vertical length of the cylindrical portion." In this way, even if the closed space of the compartment S3 is narrowed, i.e., the "internal volume (V) of the container" is reduced, the same resonance effect can be obtained by adjusting the vertical length of the cylindrical portion, i.e., the "neck length (L) of the opening." In particular, if the cylindrical portion is provided inside the closed space of the compartment S3, the cylindrical portion cannot be seen from the outside, and therefore the aesthetic appearance is not impaired and soundproofing effect is improved.

[0072] In addition, in the embodiment, the closed space functioning as a Helmholtz resonator has been described as a plurality of compartments S3 formed by dividing the support internal space S2 by the dividers 33, but the entire support internal space S2 formed by the lower support member 31 and the plate member 32 without the dividers 33 may also be considered as a closed space.

[0073] In addition, in the embodiment, it has been explained that the multiple compartments S3, which are closed spaces that function as Helmholtz resonators, do not have to be sealed spaces, but of course the multiple compartments S3 may be configured as sealed spaces.

[0074] Furthermore, in the embodiment, an example in which one through-hole is provided in each closed space has been described, but the number of through-holes provided in one closed space is not limited to one and may be multiple. [Explanation of symbols]
