Description

[Technical Field]

[0001] The present disclosure relates to soundproof doors. [Background technology]

[0002] Soundproof doors are often installed at the entrances and exits of soundproof rooms such as musical instrument practice rooms and karaoke rooms. For example, Patent Document 1 discloses a soundproof door installation structure in which a magnetic packing is attached to a door stop along the inner periphery of the door frame, and a magnetic sheet is installed on the part of the soundproof door that comes into contact with it to enhance soundproofing. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2017-179893 Summary of the Invention [Problem to be solved by the invention]

[0004] In conventional soundproof doors like those described above, the door stop is tightly fitted to the magnetic packing, sealing the door panel on three sides (the left and right ends and the top) when the door panel is closed. This prevents sound leakage from three sides of the door panel. However, the bottom end of the door panel does not have a magnetic packing, which creates a gap and reduces the soundproofing effect. Furthermore, if the door stop and magnetic packing were fitted to the bottom end of the door frame, they would protrude from the floor, making it easy to trip when walking, which is undesirable from the perspective of barrier-free access.

[0005] The present disclosure has been made in consideration of the above-mentioned problems, and its purpose is to provide a soundproof door that can improve not only soundproofing performance but also at least one of barrier-free access, airtightness, and operability. [Means for solving the problem]

[0006] In order to achieve the above-mentioned object, the present disclosure provides a soundproof door comprising a frame body having an upper frame portion, a left frame portion, and a right frame portion, and a door body which is a hinged door attached to the frame body so as to be able to open and close, wherein a concave groove portion which is continuous with the left frame portion and the right frame portion is embedded in the floor below the door body, a magnetic gasket which contains a magnetic material and is elastically deformable is disposed in the groove portion, an attraction member which is magnetic and attracts the magnetic gasket by magnetic force is provided at the lower edge of the door body, and when the attraction member approaches the magnetic gasket, the magnetic gasket changes from being immersed in the groove portion to being bulged out above the groove portion, so as to be in close contact with the door body.

[0007] Furthermore, in the soundproof door, it is preferable that the adsorption member is capable of moving up and down between a lower end position at the lower edge of the door body and a retracted position above the lower end position, and that at the lower end position it is in close contact with the magnetic gasket that bulges out from the groove, and at the retracted position the magnetic gasket detaches and sinks into the groove.

[0008] In the soundproof door, it is preferable that the suction member is provided so as to be displaceable up and down by rotating a lever handle provided on the door body.

[0009] In addition, in the soundproof door, it is preferable that a storage space for storing the suction member is provided along the width direction of the door body at the lower edge portion of the door body, and the suction member has a length corresponding to the width of the door body.

[0010] In addition, in the soundproof door, it is preferable that the magnetic packing is a hollow rubber packing with a plate-shaped or sheet-shaped magnetic body attached to the upper inner periphery, and that the magnetic body is in surface contact with the adsorption member via the bulging magnetic packing.

[0011] Furthermore, in the soundproof door, it is preferable that a doorstop is provided inside the frame, and a magnetic packing is interposed between the doorstop and the door body, and when the door body is closed against the frame, the packing provided on either the doorstop or the door body comes into close contact with a magnetic member provided on the other of the doorstop or the door body.

[0012] Furthermore, in the soundproof door, when the door body is closed against the frame, it is preferable that the bulging magnetic gasket adheres closely to the gasket provided on either the doorstop portion or the door body, or to the magnetic member provided on the other of the doorstop portion or the door body.

[0013] Furthermore, in the soundproof door, the gasket is divided into L-shaped corner gaskets and straight section gaskets extending vertically or horizontally on the inside of each of the corners between the upper frame section and the left frame section and the corners between the upper frame section and the right frame section, and it is preferable that the corner gaskets have first fitting portions at both ends, and the straight section gaskets have a second fitting portion at at least one end that fits into the first fitting portion. [Effects of the Invention]

[0014] According to the present disclosure, it is possible to improve the soundproofing performance of a soundproof door while also enhancing barrier-free access, airtightness, and operability. [Brief explanation of the drawings]

[0016] Hereinafter, a soundproof door according to an embodiment of the present disclosure will be described with reference to the drawings.

[0017] 1 and 2 are front views showing the appearance of a soundproof door 1 according to an embodiment of the present disclosure, with FIG. 1 showing the soundproof door 1 in a closed state and FIG. 2 showing the soundproof door 1 in an open state.

[0018] The soundproof door 1 is installed, for example, between a room and a hallway leading to the room. The soundproof door 1 illustrated in FIG. 1 includes a frame 2 and a door body 6. The frame 2 includes an upper frame portion 21, a left frame portion 22, and a right frame portion 23. In the illustrated embodiment, the door body 6 is a single-wing hinged door that is attached to the right frame portion 23 via a hinge or the like (not shown) so as to be able to open and close. The door body 6 is configured to open and close the opening surrounded by the frame 2 by rotating relative to the right frame portion 23 of the frame 2.

[0019] The door body 6 is provided with a lever handle 7 connected to a latch device (not shown) housed inside. The lever handle 7 is provided on the door edge side of the door body 6. The door body 6 can be opened and closed using the lever handle 7.

[0020] As shown in Figure 2, the soundproof door 1 has a doorstop 3 protruding from the inside of the frame 2, and is structured so that when the door body 6 is closed, the door body 6 abuts against the doorstop 3. A magnetic first gasket 31 is provided between the doorstop 3 and the door body 6. More specifically, the first gasket 31 is provided at the portion of the doorstop 3 that abuts against the door body 6, and an iron plate 61, which is a magnetic member, is provided at the portion of the door body 6 that abuts against the doorstop 3.

[0021] The first packing 31 is made of, for example, magnet rubber, and is a magnetic packing (magnetic packing). The first packing 31 is provided continuously along the width direction and the up-down direction on the facing surfaces (surfaces facing the door body 6) of the door stop part 3 corresponding to the inside of the upper frame part 21, the inside of the left frame part 22, and the inside of the right frame part 23.

[0022] The iron plates 61 are disposed along the width and vertical directions on the door stop surfaces on three sides located inside the upper frame portion 21, the left frame portion 22, and the right frame portion 23 when the door body 6 is closed. In this case, the iron plates 61 are provided so as to be flush with the door stop surfaces of the door body 6.

[0023] As a result, when the door body 6 is closed against the frame 2, the first gasket 31 of the door stop 3 is pressed against the iron plate 61 of the door body 6, and they are brought into close contact with each other by magnetic force, sealing off any gaps that may form between the door body 6 and the frame 2. This prevents sound leakage from above and on the left and right sides of the soundproof door 1.

[0024] In this embodiment, the first gasket 31 is configured to include corner gasket 31b at the corner between the upper frame portion 21 and the left frame portion 22, and inside the corner between the upper frame portion 21 and the right frame portion 23 shown in Figure 2.

[0025] 3 is an explanatory diagram showing an example of the assembly configuration of the first packing 31. The first packing 31 is divided into a corner packing 31b and linear packings 31a and 31c. The corner packing 31b, which forms the corner portion, is a one-piece packing including portions extending vertically and horizontally, and is formed in a substantially L-shape. Fitting recesses 33 serving as first fitting portions are provided at both ends of the corner packing 31b.

[0026] The straight portion packings 31a, 31c are formed in a straight line extending horizontally (widthwise) or vertically. The straight portion packing 31a extending horizontally has mating protrusions 32 as second mating portions at both ends. The straight portion packing 31c extending vertically has mating protrusions 32 as second mating portions at its upper end. These mating protrusions 32, like the straight portion packings 31a, 31c, are desirably formed to be magnetic. The mating protrusions 32 are mated and connected to mating recesses 33 of the corner portion packing 31b.

[0027] The first packing 31 may have a configuration in which the corner packing 31b has a mating protrusion and the straight-section packings 31a and 31c have mating recesses. However, the corner packing 31b is provided at a corner and has a short overall length, while the straight-section packings 31a and 31c are often arranged in the vertical direction and are long. Therefore, as shown in the example, it is more preferable to provide the corner packing 31b with a mating recess 33 and to fit the mating protrusions 32 of the straight-section packings 31a and 31c into the mating recess 33. This also improves the installation accuracy of the first packing 31.

[0028] 7 and 8 are explanatory diagrams showing corner packing configurations as reference examples. For example, as shown in FIG. 7, if the corner packing is configured by combining linearly extending packing 91a and packing 91b, a gap is likely to occur at connecting portion 91c, which may disrupt the magnetism. Also, as shown in FIG. 8, even if linearly extending packing 92a and packing 92b are butted together at their tapered ends, a gap is likely to occur at connecting portion 92c, which may disrupt the magnetism. Weakened magnetism of the corner packings leads to problems such as reduced sealing performance and soundproofing.

[0029] In contrast, in the soundproof door 1 according to this embodiment, the first gasket 31 is configured by combining the corner gasket 31b and the straight-line gaskets 31a and 31c. Therefore, even if a gap occurs between the fitting recess 33 and the fitting protrusion 32, the magnetic fitting protrusion 32 overlaps the magnetic corner gasket 31b, so the magnetism is not interrupted. Furthermore, the corner gasket 31b at the corner is a single piece, ensuring continuity of the magnetism. Therefore, the first gasket 31 is magnetic throughout, allowing for a seamless seal between the door body 6 and the doorstop 3.

[0030] Returning to Figure 2, in the soundproof door 1, doorstops 3 are provided on the inside of the upper frame portion 21, left frame portion 22, and right frame portion 23 of the frame body 2, but no doorstop 3 is provided on the floor surface 8 side. If a doorstop were provided on the floor surface 8, the doorstop would create a step that could cause people to trip when entering or exiting the soundproof door 1, which is undesirable from the perspective of barrier-free access. On the other hand, if there is a gap between the door body 6 and the floor surface 8, sound would be more likely to leak out, and soundproofing performance could be reduced.

[0031] Therefore, in the soundproof door 1 according to this embodiment, the groove 4 is recessed into the floor surface 8, and a second gasket 5 (described later) is provided in the groove 4 so that it can appear and disappear. The groove 4 is located below the door body 6 in the closed state, and extends along the width direction, continuing from the lower end of the left frame portion 22 and the lower end of the right frame portion 23.

[0032] Fig. 4 is a cross-sectional view of the groove 4 and second gasket 5 of the soundproof door 1. Fig. 4 shows a cross-section of the bottom of the door body 6 in the closed state, seen from the door edge toward the hinge.

[0033] As shown in the figure, the groove 4 is embedded in the floor surface 8 and is formed with a concave or substantially U-shaped cross section that opens upward from the floor surface 8. A second packing 5, which is a magnetic packing, is disposed in the groove 4. The second packing 5 is a hollow packing (e.g., a rubber packing), includes a magnetic body 52, and is elastically deformable. The magnetic body 52 provided in the second packing 5 is preferably a magnetic plate-like or sheet-like member, and is attached integrally to the upper inner periphery of the hollow portion 51 of the second packing 5.

[0034] 4, the second packing 5 is housed in the groove 4 and is disposed in a curved shape with its upper portion recessed downward into the groove 4. The magnetic material 52 in the second packing 5 is also disposed in a curved shape. The second packing 5 is entirely immersed in the groove 4 and is disposed without protruding above the groove 4 and the floor surface 8.

[0035] The door body 6 is provided with an attraction member 65 that magnetically attracts the second packing 5 to the magnetic second packing 5. The attraction member 65 is a magnetic strip-shaped member. As shown in Fig. 2, the attraction member 65 is continuously disposed along the width direction of the door body 6, and has a length corresponding to the width of the door body 6.

[0036] Returning to FIG. 4 , a storage space 63 for storing an adsorption member 65 is provided in the lower edge portion 62 of the door body 6. The storage space 63 is formed along the width direction of the door body 6. In the illustrated embodiment, the storage space 63 is formed in a recessed shape that is open downward, and a recess 64 is formed in the lower edge portion 62 of the door body 6. When the door body 6 is closed, the first gasket 31 of the door stop portion 3 and the iron plate 61 of the door body 6 are in close contact with each other by magnetic force. The space between the door body 6 and the frame 2 is sealed with no gaps.

[0037] The attraction member 65 is provided so as to be movable up and down between a lower end position of the storage space 63 of the door body 6 and a retracted position that is higher than the lower end position. In Fig. 4, the attraction member 65 is in the retracted position and is disposed in contact with the ceiling surface of the storage space 63. In the illustrated embodiment, the ceiling surface of the storage space 63 is formed in a curved shape that bulges upward, and the attraction member 65 also has a curved shape that follows the inner surface of the storage space 63.

[0038] As shown in Fig. 2, the lever handle 7 provided on the door main body 6 has a rotation shaft 71. The lever handle 7 is provided so as to be rotatable about the rotation shaft 71. Furthermore, the lever handle 7 is capable of operating the attraction member 65 to move up and down. The rotation shaft 71 of the lever handle 7 is connected to an operation mechanism 72 built into the door main body 6, and a rod 73 extends downward from the operation mechanism 72. The attraction member 65 is attached to the lower end of the rod 73.

[0039] An operating mechanism 72 connected to a rotation shaft 71 of the lever handle 7 moves a rod 73 up and down by rotating the lever handle 7. The attraction member 65 is provided so as to be displaceable up and down by rotating the lever handle 7 provided on the door body 6.

[0040] 5 and 6 show the operation of the adsorption member 65 and the second packing 5, with FIG. 5 showing the adsorption member 65 in the lower position and FIG. 6 showing the adsorption member 65 in the retracted position.

[0041] For example, when the lever handle 7 is rotated upward from the state shown in Fig. 4, the rod 73 is pushed downward, and the attraction member 65 descends together with the rod 73. As shown in Fig. 5, the attraction member 65 is displaced to the lower end position. At the lower end position, the magnetic force of the attraction member 65 acts on the magnetic body 52 of the second packing 5.

[0042] The shape of the upper inner periphery of the hollow portion 51 of the second packing 5 changes and bulges, and together with the magnetic body 52, it bulges out of the groove portion 4. The second packing 5 elastically deforms and comes into close contact with the attraction member 65 at its lower end position. The magnetic body 52 comes into surface contact with the attraction member 65 via the upper inner periphery of the bulging second packing 5. The magnetic force of the magnetic body 52 also causes the second packing 5 to come into close contact with the magnetic first packing 31 provided in the door stop portion 3. The recess 64 of the door body 6 is blocked by the second packing 5 bulging upward from the groove portion 4.

[0043] In this way, the second gasket 5 is embedded in the floor surface 8 and is capable of moving in and out as the suction member 65 moves up and down. The protruding second gasket 5 can seal the gap between the door body 6 and the floor surface 8 without any gaps. The iron plate 61 of the door body 6 is in close contact with the first gasket 31 of the doorstop portion 3, and the protruding second gasket 5 is also in close contact with the first gasket 31 of the doorstop portion 3, thereby sealing the gap between the door body 6 and the frame 2. Therefore, the door body 6 can be sealed without any gaps against both the frame 2 and the floor surface 8, preventing sound leakage and improving soundproofing performance.

[0044] When the lever handle 7 is rotated downward from the state shown in Fig. 5, the rod 73 is pulled back upward. The attraction member 65 rises together with the rod 73 and is displaced to the retracted position within the accommodation space 63 as shown in Fig. 6. At the retracted position, the second packing 5 is detached from the attraction member 65, and changes shape together with the magnetic body 52, becoming immersed in the groove portion 4 again.

[0045] When the second packing 5 is immersed in the groove 4 below the door body 6, nothing protrudes from the floor surface 8. Therefore, when walking through the open soundproof door 1, it is less likely to trip, and walking is made easier.

[0046] The lever handle 7 that operates the attraction member 65 may be a cremone handle having a pair of upper and lower locking rods. In this case, the door body 6 can be locked in conjunction with the rotation of the lever handle 7 to operate the attraction member 65. This further improves the operability of the soundproof door 1.

[0047] As described above, the soundproof door 1 according to this embodiment includes the second gasket 5 embedded in the floor surface 8 and provided so as to be freely projected and retracted, and the attracting member 65 that magnetically attracts the second gasket 5. When the door body 6 is open, the second gasket 5 can be recessed into the floor surface 8 and does not protrude above the floor, making the floor surface 8 barrier-free. When the door body 6 is closed, the iron plate 61 of the door body 6 and the magnetic first gasket 31 tightly seal three sides, and the gap between the door body 6 and the floor surface 8 is tightly sealed by the protruding second gasket 5 and also by the tight contact between the second gasket 5 and the first gasket 31. As a result, the four peripheries of the door body 6 are tightly sealed, ensuring airtight continuity and enabling significantly improved soundproofing and noise reduction.

[0048] In the soundproof door 1, the first packing 31 is not limited to being made of magnetic rubber, and may be made of any material as long as it is a magnetic packing. In addition, in the door body 6, the magnetic member provided at the portion where the door stop 3 abuts is not limited to the iron plate 61, and may be made of any material as long as it is a magnetic material, such as a magnetic flat or sheet-like member, such as a magnetic sheet.

[0049] Similarly, the second packing 5 is not limited to the above-described configuration and may be configured in any way as long as it is a magnetic packing that contains a magnetic material and is elastically deformable. For example, the second packing 5 may contain a magnetic material, and may be formed by kneading a powdered magnetic material into a packing material, so that the second packing 5 itself has magnetic properties. Furthermore, the magnetic material 52 does not have to be formed integrally with the second packing 5, and may be an independent member separate from the second packing 5.

[0050] It is also desirable that the second packing 5 and the magnetic body 52 have a deformation property that allows them to swell and sink without difficulty and a durability property that allows them to withstand repeated deformation. Furthermore, it is preferable that the second packing 5 is replaceable, and that it can be replaced with a new one as needed depending on the period of use.
