Description

The present invention relates to a detachable soundproof curtain, and more particularly to a highly versatile soundproof curtain that is easy to attach and detach, can be easily adapted to a change in installation location, and can be used as a partition.

In companies, offices, stores, etc., there are cases where the surrounding sounds become a concern. For example, in a workplace where customers are dealt with over the phone, the surrounding voices often become noise. There are cases where one room is divided by a partition and used as a "meeting booth" or "customer service desk", but the surrounding sounds can be a concern.

Moreover, not only the sound inside the room but also the sound coming into the room from the outside and conversely leaking from the room to the outside may be a concern. For example, the noise of cars, trains, factories, etc., and the noise of downtown areas and shops that are open late at night enter the room, making it difficult to have a conversation indoors. It may cause you to get tired and disturb your restful sleep. In addition, there are concerns that the sounds of musical instrument practice in the room may leak outside and cause a nuisance in the neighborhood.

Especially in recent years, the number of people working from home and remote work has increased, so the problem of noise in houses, which used to be less of a problem, tends to increase.

A soundproof wall can be installed to soundproof the room, but if you want to install a soundproof wall in the room of an existing building or house, it is often necessary to carry out renovation work that requires time and money. When installing a soundproof wall, the size must be measured individually according to the place of installation, and the size must be adjusted by manufacturing a dedicated soundproof wall according to the size or cutting it on site.

In addition, it is troublesome to attach the device to the ceiling, floor, wall, or the like with metal fittings. For this reason, it is difficult for amateurs to install it, and it is common to ask construction companies, renovation companies, dealers, etc. to install it.

Moreover, in rented houses and rental offices, it is prohibited to damage walls, ceilings, etc., and it has often been difficult to install soundproof walls. In such a place, the only thing that can be done is to put a screen-type partition on the floor. Originally, partitions were used for the purpose of blindfolding, and although they could block the line of sight, it was difficult to obtain a high level of soundproofing.

Therefore, there has been a demand for a soundproofing means that can be easily installed without damaging walls and ceilings, even if the soundproofing effect is slightly reduced. As such soundproof means, various methods have been proposed in the past.

For example, Japanese Unexamined Patent Application Publication No. 2021-25250 proposes a "assembly-type soundproof wall" as a soundproof wall that can be installed without damaging walls, ceilings, etc., regardless of the size of the place where it is installed. This "assemblable soundproof wall" is a prefabricated soundproof wall in which soundproof panels can be assembled into a self-supporting state. It is assembled by screwing to

According to this, since the soundproof panel stands on its own, it can be installed without strictly measuring the dimensions of the installation location. In addition, since the soundproof panel can be arranged without processing and fixing the walls and floors, it can be installed in a rental office, a rented house, etc. without any problem.

However, since it is necessary to use a plurality of large and heavy struts, such as steel angle members, and many screws to fix the soundproof panel, the equipment must be exaggerated. Therefore, not a little time and labor are required for assembly and installation. In addition, it is necessary to manufacture a special soundproof panel, such as providing a screw hole. Furthermore, the appearance is rugged, and although it is good when installed in a factory, it is hesitant to install it in an office or a house.

It can be disassembled by removing the screws, but it takes time and effort to remove many screws.

In addition, they must be assembled into a three-dimensional shape that supports each other as a whole so that they do not fall down, and cannot be used as a planar partition. Therefore, there has been a demand for a soundproofing means that can be installed more easily and has high versatility.

Also, it is known to hang soundproof curtains on windows for soundproofing between the outdoors and indoors, but soundproof curtains are basically nothing more than thick cloth and cannot be expected to have a great soundproofing effect. If you want to improve the soundproofing effect, you can make a special soundproof panel for the window and attach it to the window.

However, when a soundproof panel is attached to a window, it is necessary to manufacture a soundproof panel that is precisely matched to the vertical and horizontal sizes of the window and attach it to the window frame, which is custom-made and expensive. In addition, since the size is fixed, there were times when the window size was different and could not be used when moving house.

Japanese Patent Application Laid-Open No. 2021-25250

To provide a versatile soundproof curtain which can be easily attached and detached, does not damage the place of installation, can flexibly cope with the size of the place of installation, and can be used as a partition.

The soundproof curtain (1) according to claim 1 is a cloth soundproof curtain (1) that is used by hanging it from a horizontal strut (10), and has a horizontal strut thread through which the horizontal strut (10) is passed at the upper end. A loop (2) is provided, and a plurality of cylindrical or pocket-shaped storage portions (3) are provided below the loop (2) through which the horizontal struts are passed, and the storage portions (3) have a sound absorbing or sound insulating effect. It is characterized in that a soundproof member (4) having a can be detachably stored.

According to this, the soundproof curtain (1) in which the soundproof member (4) is stored in the storage part (3) can be obtained, and a soundproof effect higher than that of a normal soundproof curtain can be obtained. Since it can be used by hanging it from the horizontal strut (10), it is easy to install and move. It can be attached to a window and used as a partition in a room, and the soundproofing effect in the room can be easily enhanced. Also, by using a plurality of them, a soundproof space (31) can be created in the room.

The soundproof curtain (1) according to claim 2 is the soundproof curtain (1) according to claim 1, wherein an opening/closing means for opening and closing the opening (3a) of the storage section (3) is provided in the vicinity of the opening (3a). It is characterized by being

According to this, the opening (3a) through which the soundproof member (4) is put into and taken out of the storage section (3) can be closed by the opening/closing means, so dust is less likely to enter the storage section (3). Also, it is possible to prevent part of the soundproof member (4) placed in the storage part (3) from jumping out during use.

According to the present invention, it is easy to install and remove, it does not damage the installation site, it can be flexibly adapted to the size of the installation site, and it can be used as a soundproof window or as a partition. can provide. Furthermore, if you use more than one, you can easily create a soundproof space in the room.

The figure which showed Example 1 (front). The figure which showed Example 1 (side surface). 4A and 4B are views for explaining length (height) adjustment in the first embodiment; FIG. FIG. 4 is a diagram showing an example of arrangement of the first embodiment; The figure which showed Example 2. FIG. The figure which showed Example 3. FIG. The figure which showed Example 4. FIG. The figure which showed Example 5. FIG.

The present invention will be described below using preferred embodiments.

FIG. 1 is a diagram showing a state in which the soundproof curtain (1) of the present invention is used, and shows a front view of the soundproof curtain (1) attached using a tension rod (11). FIG. 2 is a side view of the same embodiment, omitting the tension rods 11 on both sides for easy understanding of the construction.

(11) is a tension rod for tensioning between the floor (22) and the ceiling (21), and the length can be adjusted by turning the length adjusting part (11a) to expand and contract. Therefore, it is possible to flexibly adapt to the height of the ceiling (21) of the installation location.

A horizontal strut (10) is detachably attached to the top of the two tension rods (11), and the two tension rods (11) are connected by the horizontal strut (10). The tension rod (11) and the horizontal strut (10) may be connected by hooks, screws, or the like, regardless of the method of connection.

(1) is a soundproof curtain made of fabric, and has a loop portion (2) through which the lateral struts (10) are passed through at the upper end for hanging from the lateral struts (10). Below the horizontal strut through loop portion (2), five storage portions (3) for storing the soundproof members (4) are arranged in a vertical direction.

The storage part (3) has a tubular shape with openings (3a) on both left and right sides, and the soundproof member (4) can be inserted and stored detachably from either of the left and right openings (3a). In addition, the storage part (3) may be shaped like a pocket with an opening (3a) provided only on either the left or right side.

The size, number, and arrangement of the storage units (3) may be appropriately determined in consideration of the shape, size, etc. of the soundproof member (4). In order to enhance the soundproofing effect, it is desirable to arrange the soundproof member (4) over as wide an area as possible.

As the soundproof member (4), any material can be used as long as it has a sound absorbing effect and a sound insulating effect. A plate-like shape is easy to use, but any shape can be used as long as it can be stored in the storage unit.

For example, commercially available acoustic panels can be used. Soundproof panels include glass wool, felt, urethane sponge, porous plates, gypsum boards, rubber sheets, metal foils, lead sheets, resin sheets, and panels made by laminating them.

In addition, it is also possible to use suitable items on hand as the soundproof member (4), such as cushions, floor cushions, futons, pillows, sponges, bath towels, mats, cardboards, cotton, packing materials, and the like. The soundproof effect varies depending on the type and amount of the soundproof member (4) stuffed into the storage section.

In this example, a composite panel made by laminating high-density glass wool and lead sheets was used as the soundproof member (4).

Since the soundproofing member (4) can be easily attached and detached, it is also possible to select and use soundproofing members (4) having soundproofing effects with different properties depending on changes in the surrounding environment. For example, even when the ambient sound changes with the seasons, it is possible to flexibly cope with the situation by exchanging the soundproof member (4).

Since the soundproof member (4) itself is housed inside the housing portion (3) and is hardly exposed to the outside after installation, there is no need to apply a design treatment such as cloth covering to the surface. Since the soundproof curtain (1) that can be seen from the outside is made of cloth, it does not feel oppressive even if it is installed, and it is easy to provide curtains with different designs and colors according to fashion and taste. For example, you can enjoy it like a tapestry if you make it with cloth printed with photos or illustrations.

When the soundproof curtain (1) becomes soiled, it can be removed from the lateral support (10), the soundproof member (4) removed from the storage section (3), and washed in the same manner as an ordinary curtain.

The soundproof curtain (1) of the present invention makes it difficult for sound to reach the opposite side. In addition to the sound absorbing and sound insulating effects of the soundproof member (4), depending on the thickness, material and weaving method, the cloth of the curtain itself can also provide a certain level of soundproof effect.

Even if the ceiling height of the room changes due to moving, etc., the tension rod (11) can be expanded and contracted, so it can be accommodated. In addition, since the soundproof curtain (1) is made of cloth, a hard soundproof member is inserted, but it can be bent except for the part. Therefore, by bending the bottom portion of the soundproof curtain (1), changes in ceiling height can be accommodated.

FIG. 3 is a diagram showing the case of installation in a room with a low ceiling height. Since the ceiling is low, the length of the soundproof curtain (1) is excessive and the hem touches the floor (22). In that case, the hard soundproof member (4) should not be placed in the lowest storage part (3b), and the hem should be kept along the floor (22). In that case, the gap between the soundproof curtain (1) and the floor (22) is eliminated, so the soundproofing effect is further enhanced.

In this embodiment, one soundproof curtain (1) is attached to one lateral support (10), but if necessary, multiple soundproof curtains (1) are attached to one lateral support (10). You can make it work. In that case, it is desirable to use the horizontal struts (10) having sufficient strength in consideration of the weight of the soundproof member (4).

It is not easy to create a soundproof room due to housing conditions and costs, but if multiple units of this embodiment are used, a simple soundproof space (31) can be created in the room.

The arrangement and the number of soundproof curtains (1) to be used may be appropriately determined according to the shape and size of the room (30), the desired installation location, and the desired size of the soundproof space (31). FIG. 4 shows three patterns in which four soundproof curtains (1) are arranged to partition a room (30) to provide a soundproof space (31).

Fig. 4(A) shows a state in which a soundproof space (31) is provided by dividing the entire room (30) into two, and Fig. 4(B) shows a soundproof space (31) using a corner of the room (30). FIG. 4(C) shows an example in which a soundproof space (31) is provided using the wall of the room (30).

When the soundproof curtains (1) are arranged side by side, the tension rods (11) of the adjacent soundproof curtains (1) may also be used. In this case, it is possible, for example, to install two soundproof curtains (1) with three tension rods (11).

Such a soundproof space (31) can be used, for example, as a space for practicing a musical instrument such as a piano, or as a private room for quietly concentrating on study or work.

In the arrangement shown in Fig. 4, the soundproof curtain (1) was placed so as to secure a passage to enter the soundproof space (31). Sometimes, the hem of the soundproof curtain (1) can be rolled up and passed through.

The soundproof curtain (1) is only attached to the horizontal support (10) by means of loops (4a) through which the upper end of the horizontal support is passed, and the lower part is not fixed. You can temporarily create a space to pass through, so you can use it as a passage.

FIG. 5 is a diagram showing this embodiment. This embodiment is an example in which it is attached to a sweep window. In the first embodiment, the horizontal struts (10) are attached to and held by the left and right tension rods (11), and the soundproof curtain (1) is suspended from the horizontal struts (10). Instead of using the hooks (12), the horizontal struts (10) are held.

A hook (12) is attached to the top of the sweep window frame (23). The hook (12) may be of the type that is fixed to the wall or window frame with nails, wood screws, double-sided tape, magnets, suction cups, clamps, etc., or of the type that is used by hooking on the window frame, such as an S-shaped hook. It's okay. The basic configuration of the soundproof curtain (1) is the same as in the first embodiment.

The opening area of the sweep-out window is large, and sound intrusion from the outside and sound leakage from the room are likely to be a problem. . If you want to go in and out through the sweep window, you can remove the soundproof curtain (1), or you can roll up the hem and pass through.

FIG. 6 is a diagram showing this embodiment. In Example 1, a tension rod (11) was used, and in Example 2, a hook (12) was used to hold the horizontal support (10). It was attached by resting the end (10a) of the lateral strut (10).

If there are appropriate shelves (25) on both sides, the end (10a) of the horizontal strut (10) can be placed without using a tension rod (11) or hook (12), making installation even easier. I can do it. The basic configuration of the soundproof curtain (1) is the same as in the first embodiment.

The present embodiment is an embodiment in which it is attached to a window (high-waisted window) and used. FIG. 7 shows this embodiment, which is attached using a tension rod (11) as in the first embodiment. In the first embodiment, the tension rod (11) is arranged between the ceiling (21) and the floor (22), but in this embodiment, it is arranged between the upper side (24a) and the lower side (24b) of the window frame (24). Place the tension rod (11) so that it is tensioned.

In this embodiment, the tension rod 11 is used for fixing, but as in the second embodiment, a locking member such as a hook 12 is attached to the window frame 24, and the horizontal strut is attached to the locking member. (10) may be retained.

FIG. 8 is a diagram showing this embodiment. In the first embodiment, openings (3a) are provided on the left and right sides of the storage section (3) to form a cylindrical shape so that the soundproof member (4) can be taken in and out from the horizontal direction of the storage section (3a). An opening (3a) is provided above the storage portion (3) to make the storage portion (3) pocket-shaped. The left and right sides of the storage part (3) are sewn together and do not have an opening.

In this embodiment, the soundproof member (4) can be taken in and out through the opening (3a) above the storage portion (3). Since each storage section (3) is pocket-shaped, the soundproof member (4) does not fall downward.

In this embodiment, the storage section (3) is smaller than that used in the first embodiment, and a total of 10 storage sections (3) are provided in two rows in the horizontal direction and five rows in the vertical direction. An opening/closing means may be provided in the vicinity of the opening (3a) of the storage portion (3) so that the opening (3a) can be opened and closed. As the opening/closing means, members such as fasteners, surface fasteners, hooks and buttons can be used.

By closing the opening (3a) with the opening/closing means, external dust and the like can be prevented from entering the storage section (3). In addition, when cotton, feathers, resin beads, or the like is used as the soundproof member (4) to be placed in the storage portion (3), it is possible to prevent a part of them from leaking out.

The present invention can be used for business purposes such as companies, companies, offices, and schools, as well as for general home use and remote work.
