Conventional soundproof booths with good soundproofing characteristics are relatively expensive, and inexpensive simple types are said to have drawbacks in soundproofing characteristics and durability. Hereinafter, embodiments of the present invention will be described with reference to the drawings. The present invention was born from the development of trial and error by the inventor in order to solve the problems of the conventional soundproof booth.

There are two types of sounds: "air sounds" that travel through the air and reach your ears, and "solid sounds" that you can hear footsteps and falling sounds of objects traveling through the floor and walls. "Air sound" is the sound transmitted through the air such as the sound of jet planes, automobiles, and musical instruments, and "solid sound" is the sound of footsteps and speakers on the upper floors, the sound of trains and trucks, and toilets. It is a sound that is heard by vibrating an object, such as the sound of drainage.

The ability of each part of a house to block noise is called sound insulation performance and is represented by a D value (a numerical value representing the sound insulation of air sound). In a wooden house with general specifications, the sound insulation performance of the wall is said to be about D-40 (outer wall) and D-30 (inner wall). If it is a detached house, the target that is considered to be noisy is the next house, and if it is an apartment house such as an apartment, the target is the next upper and lower floor dwelling units. Depending on the use of the living room or the like in the target house, the allowable noise is "about 40 to 45 dB" in the living room or the like.

On the other hand, the sound pressure level emitted from the musical instrument that is the sound source is 95 dB to 105 dB when playing the tenor saxophone or trumpet, so D-65 is required to make the sound pressure level acceptable in the living room about 40 to 45 dB. Desired. To lower the sound pressure level, there are sound absorption that absorbs the sound from the sound source and sound insulation that shields the sound between the sound source and the observation point, and it is necessary to combine both to improve the soundproofing effect.

Assuming that the sound insulation performance with the neighboring house is the average D-35, the sound insulation performance required for the soundproof booth is D-30, which is the provisional target sound insulation characteristic of the soundproof booth. Further, the invention of the present application also aims to make the packaging size smaller so that the invention can be purchased by an individual by mail order or the like. It is also important to provide a structure that can be easily assembled by an individual at a low cost.

[First Example]
The soundproof booth 100, which is the first embodiment of the present invention developed based on the above requirements, will be described below. FIG. 1 is a perspective view of the appearance of the first embodiment. The dimensions were about 180 cm in width, about 90 cm in depth, and about 200 cm in height. These dimensions are selected from the standard lengths of commercially available materials while listening to the user's voice. The width is 90 cm, which is half of the above, and it is easy to manufacture.

As shown in FIG. 1, the whole is box-shaped, and the front members 1 and 2 that form the door to be the entrance and provide the door function, the right member 3 to be the side surface, the rear members 4, 5, and the roof member 7 to be the ceiling. Form a box with. Each plate-shaped member is connected by a hinge described later, but there is a gap between the plate-shaped members in order to ensure mutual mobility. The soundproofing characteristics are improved by closing the gap with the soundproofing member 9 for the gap. A thick cloth, a flexible soundproof sheet, or the like is suitable for the gap soundproof member 9.

The rear member is provided with a tension rod 102 for preventing a fall, which will be described later. It is preferable to attach the non-slip 103 to the mounting surface in contact with the ceiling and the top plate. A pedestal may be provided and a compression spring may be inserted in the receiving portion to urge the pedestal in the extension direction. Since the door is closed to ensure soundproofing, a ventilation fan 110 capable of intake and exhaust for ventilation is provided. Further, an additional sound absorbing member 104 may be further used for the rear member in consideration of placing the soundproof booth near the wall near the neighboring house. The inside of the soundproof booth will also be supplied with the necessary power for lighting.

As shown in FIG. 2, the soundproof booth 100 of the first embodiment is formed by adding a sound insulating sheet and a sound absorbing member to be described later to pipe frames 10, 20 ... 70 as plate-shaped members constituting the soundproof booth 100. Hereinafter, the folding of the soundproof booth 100 of the first embodiment will be described. FIG. 2A shows how the roof member 70 connected to the rear members 40 and 50 by a hinge, which will be described later, begins to descend. FIG. 2B shows how the front members 10 and 20 are folded inward.

FIG. 3A shows a state in which the roof member 70, the left front member 10, the right front member 20, the right member 30, and the left member 60 are folded toward the rear members 40 and 50. FIG. 3B is a plan view of the pipe in the folded state. The back members 40 and 50 are located close to FIG. 3 (A) in FIG. 3 (B), and then the roof member 70 is folded. Further, the front members 20 and 30 come, and finally the left member 60 and the right member 30 are folded. When all the plate members are folded so that the members other than the rear member overlap the rear member, the depth thereof becomes as small as four plate members plus the hinge size.

As the depth of the folded soundproof booth 100 becomes smaller, it becomes easier to fall down, so it is necessary to devise ways to prevent it from tipping over. As shown in FIG. 3A, by mounting the tension rods 102 fixed to the rear members 40 and 50 between the ceiling and the floor, it is possible to prevent the soundproof booth 100 from falling over. Further, if the soundproof booth 100 is near the wall surface, the rear members 40 and 50 may be supported by a fall prevention tool having a fixed portion adhered to the wall surface. Further, although a protrusion is generated on the floor, a ski plate-shaped member may be fixed to the rear members 40 and 50.

FIG. 4 shows the structure of the plate-shaped member. The sound insulation sheet 300 is fastened to the pipe frame, which is a frame made of pipes, with a binding band or the like. In the soundproof booth, the sound absorbing material 301 is fixed to the indoor side of the sound insulating sheet by adhesive or the like. When sound is incident on the sound absorbing material 301, friction or fine vibration is generated in the sound absorbing material to generate heat energy, thereby absorbing sound. Specifically, glass wool, felt, urethane sponge, etc., which are porous sound absorbing materials, are excellent in cost performance.

The structure of the variable length tension rod mainly arranged between the floor and the ceiling will be described with reference to FIGS. 5 and 6. The tension rod 102 used in the present invention has one end connected to a telescopic portion composed of a first member and a second member housed therein, and a lower end portion of the second member housed in the first member. A pulling member pulled out of the first member through a guide portion between the upper end portion of the member and the lower end portion of the second member, and a member fixed to the first member to lock the pulling member. It is characterized by having a stop and can be expanded and contracted. Here, the shapes of the first member and the second member are arbitrary, and in addition to a round pipe having a circular cross section and a square pipe having a square cross section, the second member moves up and down along a guide portion provided on the first member. It may be a flat plate. Further, a flexible rope or belt is suitable for the pulling member. The guide portion may be provided with a groove in the first member or the second member.

As the tension rod 102 used in the present invention, a round pipe was used as the first member 202 and the second member 201 within the first member 202. As shown in FIG. 5, it has a structure in which a small diameter pipe 201 and a large diameter pipe 202 are combined and a belt 203 is locked to an end portion of the small diameter pipe. The belt may be locked to the small diameter pipe by fixing with a stud or a screw, but the end of the belt may be adhered to the small diameter pipe.

Before adjusting the length of the tension rod, as shown in FIG. 5A, the small diameter pipe 201, which is the second member, is housed in the large diameter pipe 202, which is the first member, and one end at the end of the small diameter pipe. The belt 203 locked with the belt 203 is pulled out through the space between the outer wall of the small diameter pipe and the inner wall of the large diameter pipe. In FIG. 5, the length of the small diameter pipe 201 is drawn longer than the length of the large diameter pipe 202, but the length of the small diameter pipe may be the same as or shorter than the length of the large diameter pipe. Further, it is desirable that the belt 203 is longer than the length of the small diameter pipe.

The principle of adjusting the length of the tension rod of the soundproof booth of the present invention will be described with reference to FIG. In FIG. 5, a buckle storage unit 205 containing a DC buckle that locks the belt is added to the upper end of the large-diameter pipe. In FIG. 5A, a tension rod in which the small diameter pipe 201 is housed in the large diameter pipe 202 and the length is short is drawn. The belt 203 protruding from the edge of the large-diameter pipe is passed through a DC buckle that functions as a locking portion housed in the locking portion container 205, and the extra length hangs down.

As shown in FIG. 5B, when the rope hanging out of the large-diameter pipe 202 of the belt 203 is pulled downward, one end of the belt 203 connected to the end of the small-diameter pipe 201 folded back by the DC buckle is lifted. , The small diameter pipe 201 moves upward and the length of the tension rod becomes longer.

FIG. 6 will explain how the belt 203 is passed through the DC buckle 206 housed in the DC buckle storage portion 205, which is the locking portion of the tension rod, and the belt is locked by the DC buckle 206. In FIG. 6A, the release lever 263 is pushed by a finger while the belt is passed, and the locking teeth 261 are floating. In this state, the belt 203 can move freely. In FIG. 6B, the locking tooth 261 is pressed against the roll, and when the small diameter pipe 201 is lowered and the belt is pulled, the belt 203 is locked by the locking tooth 261 and the small diameter pipe is lowered and the belt is pulled downward. When it is struck, the lock becomes stronger.

As shown in FIG. 6A, the belt 203 passes between the roller 262 and the locking teeth 261 and is folded back at the edge of the large diameter pipe 202. The locking teeth 261 are urged in the roller 262 direction by a built-in spring, and when the belt is pulled in the direction of the arrow, the locking teeth bite into the belt and exhibit a locking function in which the movement of the belt is prevented. Then, when the release lever 263 is pushed, the belt can move freely and the locking function is released. In order to hold the locking tooth 261 in a floating state, the release lever 263 is pushed and the release holding lever 207 is tilted inward. When the release holding lever 207 is extended to the outside, the release lever 263 is lifted by the spring, the locking teeth 61 bite into the belt, and the movement of the belt is locked.

A hinge connecting the pipes of the first embodiment of the present invention will be described with reference to FIG. 7. The two pipes 20 and 30 are connected by the sandwiching members 801, 802. The sandwiching members 801, 802 are each provided with two concave surfaces, and the pipes to be connected fit into the concave surfaces and are stable. In that state, the screw member 803 is used to narrow the distance between the two sandwiching members 801, 802, and the distance between the two pipes is fixed. Since the pipes 20 and 30 can be rotated in the concave surface of the sandwiching member depending on the tightening condition of the screws, the angle formed by the plate-shaped member composed of the pipes 20 and 30 can be freely selected.

A belt-type hinge connecting the pipes of the first embodiment of the present invention will be described with reference to FIG. Two pipes 450 and 451 are connected by a belt type hinge 400. As shown in FIG. 8A, the two pipes are arranged side by side and the belt 401 is circulated around the two pipes at appropriate intervals. Positioning members 455,456,457,458 are used to determine the position of the belt.

A method of fixing the belt 401 will be described with reference to FIG. 8B. First, the belt rear end portion 402 is fixed by the fixing portion 461 of the DC buckle 460. The belt is cut to an appropriate length and the belt tip portion 403 is passed through the gap of the locking portion 463 of the DC buckle. The gap of the locking part is narrowed by the locking teeth urged by the spring and moves freely in the direction of the arrow on the belt in FIG. 8B, so pulling the tip of the belt goes around the two pipes. You can adjust the length of your belt. When loosening the belt, the locking release lever 462 of the DC buckle 460 is pushed toward the DC buckle main body to release the locking by the locking teeth.

FIG. 9A shows a state in which the angle between the A pipe frame 480 and the B pipe frame 481 connected by a belt type hinge is 180 degrees. FIG. 9B shows a state in which the angle between the A pipe frame 480 and the B pipe frame 481 is 180 degrees. Since the pipe frame becomes a plate-shaped member of the soundproof booth and the angle between the plate-shaped members can be freely set, a foldable soundproof booth can be easily configured. When folding and sandwiching another plate-shaped member between two plate-shaped members, the distance between the predetermined plate-shaped members can be easily realized by adjusting the length of the belt.

[Second Example]
FIG. 10 shows a soundproof booth 900 using a panel material as a plate-shaped member. As the panel material, for example, plywood is suitable. A sound absorbing material 901 is attached to the inside of the panel material to improve the soundproofing characteristics. The roof member is provided with two ventilation openings, and a ventilation fan is placed on them to ventilate.

The panel material was used by connecting a veneer plate of about 90 cm square. FIG. 9 shows a connection method. As shown in FIG. 11A, two plywood plates of about 90 cm square are fastened to the frame material and connected with a commercially available hinge 963. The fixing bolts 964 are passed through the fixing holes made in the frame material to fix the two connected veneer plates to each other, and the two connected veneer plates are screwed with the fixing nuts 965. Then, a plate-shaped member of about 90 cm × about 180 cm is formed.

Since the plate-shaped member is developed as shown in FIG. 12, the roof member 970 is lowered toward the rear member 940, and the left member 960, the right member 930, and the front member 910 are sequentially folded. If you fold it, the depth will become smaller and it will become unstable, so use a fall prevention device. This time, the variable length tension rod 980 was used as in the first embodiment. In front of the rear member 940, there is a belt 981 that adjusts the length of the tension rod 980. When installing, pull this belt to adjust the length of the tension rod and stabilize the rear member. Since other plate-shaped members are assembled, even one person can easily assemble.

In Examples 1 and 2, when a white noise source was placed inside the soundproof booth and the planned pressure level was measured outside the soundproof booth, an attenuation characteristic of about 30 dB was obtained. Since the member used for carrying out the present invention is mainly a commercially available standard product, it is possible to provide the soundproof booth according to the present invention to the market at a lower cost than the conventional product. Therefore, according to the present invention, it is possible to satisfy the demand of the market with less burden on the customer, which is attributed to the development of the industry.
