Description

[Technical Field]

[0001] The present invention relates to a sound-absorbing panel that can be attached to a wall surface or the like to reduce reverberation in a room and improve the acoustic environment of the room to be more suitable for conversation, etc. [Background technology]

[0002] Most rooms in a building are constructed with parallel walls (wall to wall, ceiling to floor), and when the walls and floors are made of hard materials that easily reflect sound, the sound emitted from the sound source is repeatedly reflected between the parallel walls, creating a so-called flutter echo.When this flutter echo occurs, the reverberation (reflected sound) remains indefinitely and mixes with the new sound emitted from the sound source, drastically reducing the clarity of the sound and creating an acoustic environment in which it is difficult to hear conversations or sounds from speakers. Conventionally, in order to prevent the occurrence of the flutter echo described above, sound-absorbing materials have been installed on the walls of a room, and various sound-absorbing materials have been proposed (for example, Patent Documents 1 to 3).

[0003] There is also a known type of sound-absorbing panel, which has a structure in which a frame with a cloth (decorative fabric) stretched on the front is filled with sound-absorbing material made of polyester fiber or the like, and which is fixed and installed by being attracted to a steel wall with a magnet. This type of sound-absorbing panel not only provides the desired sound-absorbing effect, but also has the advantage that it does not require special construction for installation and can be easily installed by anyone. Furthermore, this sound-absorbing panel can be made multifunctional by adding antibacterial, antiviral, or deodorizing ingredients to the sound-absorbing material.

[0005] However, after using conventional sound-absorbing panels such as those described above for a certain period of time, the cloth (decorative fabric) on the surface may become dirty or fade. Also, if the sound-absorbing material filled inside has antibacterial, antiviral or deodorizing properties, these functions may be reduced. In these cases, the sound-absorbing panel must be replaced in its entirety, which is uneconomical. Furthermore, sound-absorbing panels installed on walls become part of the interior, but if you want to change the design of the sound-absorbing panels (for example, the color or texture of the wallpaper) to change the interior, you will need to replace the entire sound-absorbing panel, which is uneconomical. Furthermore, in terms of aesthetic appeal and functionality as a sound-absorbing panel, there are many variations possible in the color and material of the cloth (decorative fabric) on the surface and the material (mainly sound-absorbing material) that is filled inside, but it is practically difficult to commercialize each of these many combinations.

[0006] Therefore, the object of the present invention is to solve the problems of the conventional technology as described above, and to provide a sound-absorbing panel in which the outer member covered with cloth and the inner member containing sound-absorbing material can be replaced separately when the cloth (decorative cloth) on the front surface becomes dirty or faded, or when the function of the internal sound-absorbing material or the like deteriorates, and in which the combination of the outer member covered with cloth and the inner member containing sound-absorbing material can be selected as desired. Another object of the present invention is to provide a sales system for sound-absorbing panels that allows customers to select any combination of outer components covered with cloth and inner components containing sound-absorbing material, and sell sound-absorbing panels that have the design, aesthetics, and functionality that suit their preferences.

[Figure 6] FIG. 2 is a longitudinal cross-sectional view of a filling member constituting the sound-absorbing panel of the embodiment of FIG. 1. [Figure 7] 1 is a front view of a partition showing an embodiment in which the sound-absorbing panel of the present invention is used as a component of the partition. [Figure 8] FIG. 8 is a front view showing only the frame body of the partition according to the embodiment of FIG. [Figure 9] Cross-sectional view along line IX-IX in Figure 7 DETAILED DESCRIPTION OF THE INVENTION

[0013] Figures 1 to 6 show one embodiment of the sound-absorbing panel of the present invention, with Figure 1 being a front view, Figure 2 being a rear view, Figure 3 being a side view, and Figure 4 being a cross-sectional view taken along line IV-IV in Figure 2. Also, Figure 5 is a drawing showing the sound-absorbing panel separated into a sound-absorbing material holding member and a filler member, and Figure 6 is a vertical cross-sectional view of the filler member. The sound-absorbing panel of the present invention comprises a sound-absorbing material holding member 1, which is an outer frame member with a cloth (decorative fabric) stretched over the front surface, a filler member 2, which is a plate-shaped member mainly made of sound-absorbing material and is fitted inside the sound-absorbing material holding member 1, and a locking member 3 that locks this filler member 2 to the sound-absorbing material holding member 1. Examples of installation forms for the sound-absorbing panel of the present invention include (i) being detachably attached to a wall surface in a room (including the wall surface of a partition) or to a frame body that is a component of a partition by suction or adhesive means, and (ii) being detachably suspended from the ceiling via a holding means such as a wire-type hanging bracket, etc. Figures 1 to 5 show a sound-absorbing panel in installation form (i).

[0014] The sound absorbing material holding member 1 is a member in which cloth 11 (decorative cloth) is stretched on the front surface of a frame 10, and the surface portion formed by this cloth 11 becomes the front surface. The frame 10 is hexagonal in shape to match the shape of the sound-absorbing panel. There are no particular restrictions on the material of the frame 10, but it is usually made of wood or resin. The cloth 11 is stretched to cover the front surface of the frame 10, and its peripheral edge is folded behind the frame 10 and fixed to the frame 10 with an adhesive. The cloth 11 may be made of a general woven or nonwoven fabric, or may be made of a non-flammable woven fabric such as a glass fiber fabric.

[0015] The filler member 2 is a plate-like member mainly composed of sound-absorbing material 20, and is removably fitted inside the frame 10 on the back side of the sound-absorbing material holding member 1. The filler member 2 is formed in a hexagonal shape in plan view to match the internal shape of the frame 10. The sound-absorbing material 20 constituting the filling member 2 may be made of any material as long as it provides a sound-absorbing effect. However, it is typically made of a fiber aggregate such as polyester fiber or glass wool, preferably a short fiber aggregate. This short fiber aggregate is made by compressing short fibers such as polyester fiber to a predetermined density and forming it into a plate. Specifically, a short fiber aggregate can be obtained by blending polyester fiber (e.g., hollow polyester fiber) as a matrix fiber with thermally adhesive fiber, melting the thermally adhesive fiber by heat treatment, and bonding the fiber contact points of the matrix fiber with the melt. Alternatively, wool may be added to polyester fiber as the matrix fiber.

[0016] The filling member 2 of this embodiment is composed of a sound absorbing material 20 made of a plate-like fiber aggregate, and a nonwoven fabric 21 adhesively fixed to the back surface of the sound absorbing material 20. The locking members 3 are composed of fasteners such as dragonfly-type fasteners that are provided on the back side of the sound-absorbing material holding member 1 (frame body 10). These locking members 3 (fasteners) are rotatably provided at multiple locations on the frame body 10, and with the filler member 2 fitted into the sound-absorbing material holding member 1, the tip side of the locking member 3 (fastener) is rotated over the edge of the filler member 2, thereby locking the filler member 2 to the sound-absorbing material holding member 1.

[0017] Furthermore, the sound-absorbing material 20 constituting the filler member 2 can be subjected to either or both of the following: (i) antibacterial and antiviral properties can be added by attaching antibacterial and antiviral agent components, or (ii) deodorizing properties can be added by attaching deodorizing agent components. In these cases, the respective components can be attached to the sound-absorbing material by impregnating the sound-absorbing material with the antibacterial and antiviral agent or deodorizing agent or by spraying it on. Furthermore, the filler member 2 is mainly composed of the sound absorbing material 20, but may also be provided with a deodorizing material (for example, a deodorizing sheet) in addition to the sound absorbing material 20. The planar shape of the sound-absorbing panel of the present invention (the shape of the panel when laid flat) is arbitrary, and in addition to the hexagonal shape of the above-described embodiment, it may be any planar shape, such as a square, rectangle, circle, oval, pentagon, triangle, etc. Furthermore, the sound-absorbing panel does not need to be flat in the thickness direction, and can have any three-dimensional shape (for example, a mountain shape, a curved shape such as a wave shape, or an uneven shape). There are no particular restrictions on the size of the sound-absorbing panel, but generally, when the panel is laid flat, the length and width of the panel are approximately 100 to 2500 mm, and the panel thickness is approximately 10 to 100 mm.

[0018] The sound-absorbing panel of this embodiment can be removably attached to a wall surface (or a frame body that is a component of a partition; the same applies below) using any suction or adhesive means. However, from the perspective of ease and simplicity of installation, it is preferable to attach it to a wall surface (a wall surface to which a magnet can be attached) by using a magnet to attach it. For this reason, in this embodiment, magnetic sheets 4 are attached to multiple locations (four locations) on the back of the panel (the back of the filler member 2), and these magnetic sheets 4 are attached to the wall surface so that the panel can be removably attached to the wall surface. When attaching to a wall surface that does not accept magnets, an iron sheet can be adhered to the wall surface and the magnet can be attached via this iron sheet. The sound-absorbing panel can also be attached to the wall surface with adhesive tape (for example, double-sided adhesive tape). The wall surface on which the sound-absorbing panels are attached includes not only walls in the narrow sense but also ceiling surfaces and partition walls.

[0019] In addition, when the sound-absorbing panel is detachably suspended from the ceiling via a holding means such as a wire-type hanging fitting, connecting portions are provided at multiple locations on the sound-absorbing panel (sound-absorbing material holding member 1) for connecting the holding means (for example, a wire-type hanging fitting). In order to provide the sound-absorbing panel of the present invention with design and functionality that suits the customer's preferences, it is preferable to prepare a plurality of sound-absorbing material holding members 1 with different types of cloth 11 and a plurality of filler members 2 with different performance and / or functions, and combine one type of sound-absorbing material holding member 1 and one type of filler member 2 selected from among them.

[0020] The sound-absorbing panel of the present invention can be used as a component of a partition, and in this case, it is detachably attached to a frame body that is a component of the partition. Figures 7 to 9 show one embodiment of this case, with Figure 7 being a front view of the sound-absorbing panel partition, Figure 8 being a front view showing only the frame body of the partition, and Figure 9 being a cross-sectional view taken along line IX-IX in Figure 7. This sound-absorbing panel partition comprises the sound-absorbing panel A of the present invention as described above, and a frame body B to which the sound-absorbing panel A is detachably attached by suction or adhesive means. The frame body B is composed of a vertically long rectangular outer frame 5, a plate-shaped panel mounting portion 6 fitted inside the outer frame 5, and a pair of legs 7 provided at the lower end of the outer frame 5.

[0021] The frame body B can be made of wood, metal, resin, or the like. The panel mounting portion 6 is a portion for removably mounting the sound-absorbing panel A to the frame body B, and in this embodiment the panel mounting portion 6 is composed of a wooden plate-shaped main body 60 fitted inside the outer frame 5, and iron sheets 61 glued and fixed to multiple locations on this main body 60. Note that the panel mounting portion 6 may be provided only on a portion of the inside of the outer frame 5 where the iron sheet 61 needs to be placed, rather than on the entire inside of the outer frame 5. The sound-absorbing panel A is configured as in the above-described embodiment. This sound-absorbing panel A is fitted inside the outer frame 5 from both sides of the frame body B, and is attached to the frame body B by the magnetic sheet 4 on the back surface being attracted to the iron sheet 61 of the panel attachment portion 6. In this embodiment, a total of four sound-absorbing panels A are attached to the top and bottom of both sides of the frame body B. As a result of the above, a sound-absorbing panel partition is constructed, which consists of a frame body B and four sound-absorbing panels A incorporated into this frame body B.

[0022] Furthermore, in the sales system for sound-absorbing panels of the present invention, a plurality of sound-absorbing material holding members 1 with different types of cloth 11 and a plurality of filler members 2 with different performance and / or functions are manufactured in advance, and any of these sound-absorbing material holding members 1 and filler members 2 are combined to form a sound-absorbing panel, which is then sold. Furthermore, any of the sound-absorbing material holding members 1 and / or filler members 2 are sold as replacement members. In this sales system, customers can purchase sound-absorbing panels with the design and functionality that suits their preferences, and can also purchase and replace only the sound-absorbing material holding members 1 or filler members 2 as needed.
