Summary of the Invention

Problems to be Solved by the Invention

[0004] In the conventional soundproof door as described above, when the door stop adheres closely to the magnet packing, when the door panel is closed, three sides, namely the left and right ends and the upper end of the door panel, are sealed. Thereby, it is possible to prevent sound leakage from the three sides of the door panel. However, a magnet packing is not provided at the lower end of the door panel, a gap is formed, and the soundproofing effect is reduced. Further, if a door stop and a magnet packing are provided on the lower end side of the door frame, they will protrude from the floor surface, making it easy to trip during walking, which is not preferable from the viewpoint of barrier-free.

[0005] The present disclosure has been made in view of the above problems, and an object thereof is to provide a soundproof door that can improve at least one of barrier-free property, airtightness, and operability in addition to improving soundproof performance.

[0010] Furthermore, in the soundproof door, the magnetic packing is preferably a hollow rubber packing with a plate-shaped or sheet-shaped magnetic material attached to the upper inner circumference, and the magnetic material is in surface contact with the adsorption member via the bulging magnetic packing.

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

Mode for Carrying Out the Invention

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

[0017] FIG. 1 and FIG. 2 are front views showing the appearance of the soundproof door 1 according to the embodiment of the present disclosure. FIG. 1 shows the state where the soundproof door 1 is closed, and FIG. 2 shows the state where the soundproof door 1 is opened.

[0018] The soundproof door 1 is provided, for example, between a living room and a corridor connected to the living room. The soundproof door 1 illustrated in FIG. 1 includes a frame body 2 and a door main body 6. The frame body 2 includes an upper frame portion 21, a left frame portion 22, and a right frame portion 23. The door main body 6 is a single-leaf opening door that is attached to the right frame portion 23 in an exemplary form so as to be openable and closable via a hinge or the like not shown. The door main body 6 is configured to open and close the opening surrounded by the frame body 2 by rotating with respect to the right frame portion 23 of the frame body 2.

[0019] The door main 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 leading end side of the door of the door main body 6. The door main body 6 is configured to be openable and closable using the lever handle 7.

[0020] As shown in Figure 2, the soundproof door 1 has a door stop 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 comes into contact with the door stop 3. A magnetic first packing 31 is provided between the door stop 3 and the door body 6. More specifically, the first packing 31 is provided in the part of the door stop 3 that comes into contact with the door body 6, and the iron plate 61, which is a magnetic material, is provided in the part of the door body 6 that comes into contact with the door stop 3.

[0021] The first packing 31 is formed of, for example, magnetic rubber and is a magnetic packing (magnetic packing). The first packing 31 is continuously provided along the width direction and the vertical direction on the visible surface (the surface facing the door body 6) of the door stop 3, which corresponds to the inside of the upper frame portion 21, the inside of the left frame portion 22, and the inside of the right frame portion 23.

[0022] The iron plate 61 is positioned along the width and vertical directions on the three door stop surfaces 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 plate 61 is provided so as to be flush with the door stop surface of the door body 6.

[0023] As a result, when the door body 6 is closed against the frame 2, the first packing 31 of the door stop 3 is pressed against the iron plate 61 of the door body 6, and they adhere tightly to each other by magnetic force, sealing the gap between the door body 6 and the frame 2. This prevents sound leakage from the top and left and right sides of the soundproof door 1.

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

[0025] Figure 3 is an explanatory diagram showing an example of the assembly configuration of the first packing 31. The first packing 31 is formed by dividing it into a corner packing 31b and straight packings 31a and 31c. The corner packing 31b, which constitutes the corner, is a single piece of packing including portions extending in the vertical and horizontal directions, and is formed in a substantially L-shape. Fitting recesses 33, which serve as first fitting portions, are provided at both ends of the corner packing 31b.

[0026] The straight section packings 31a and 31c are formed in a straight line extending horizontally (width direction) or vertically. The straight section packing 31a extending horizontally is provided with fitting protrusions 32 as second fitting parts at both ends. The straight section packing 31c extending vertically is provided with fitting protrusions 32 as second fitting parts at its upper end. It is desirable that these fitting protrusions 32 are also formed with magnetic properties as straight section packings 31a and 31c. The fitting protrusions 32 are fitted into and connected to the fitting recesses 33 of the corner section packing 31b.

[0027] Furthermore, the first packing 31 may be configured such that a fitting projection is provided on the corner packing 31b and fitting recesses are provided on the straight section packings 31a and 31c. However, the corner packing 31b is provided at the corner and has a short overall length, while the straight section packings 31a and 31c are arranged in the height direction and are often long. For this reason, as illustrated, it is more preferable to provide a fitting recess 33 on the corner packing 31b and to configure the straight section packings 31a and 31c so that their fitting projections 32 are fitted into the fitting recess 33. This also improves the installation accuracy of the first packing 31.

[0028] Figures 7 and 8 are explanatory diagrams showing corner packing configurations as reference examples. For example, as shown in Figure 7, if the corner packing is configured with a combination of linearly extending packings 91a and 91b, a gap is likely to occur at the connection point 91c, and this gap may cause the magnetism to be interrupted. Also, as shown in Figure 8, even if linearly extending packings 92a and 92b are butted together at tapered ends, a gap is likely to occur at the connection point 92c, and the magnetism may be interrupted. When the magnetism of the corner packing weakens, problems arise such as a decrease in airtightness and a decrease in sound insulation.

[0029] In contrast, in the soundproof door 1 according to this embodiment, the first packing 31 is configured by combining a corner packing 31b and straight packings 31a and 31c. Therefore, even if a gap occurs between the fitting recess 33 and the fitting projection 32, the magnetic fitting projection 32 overlaps with the magnetic corner packing 31b, so the magnetism is not interrupted. Furthermore, the corner packing 31b at the corner is a single piece, ensuring the continuity of the magnetism. Consequently, the first packing 31 has magnetism throughout its entirety without interruption, and can seal the space between the door body 6 and the door stop 3 without any gaps.

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

[0031] Therefore, in the soundproof door 1 according to this embodiment, a groove 4 is embedded in the floor surface 8, and a second packing 5, which will be described later, is provided in the groove 4 so as to be able to extend and retract. The groove 4 is located below the door body 6 when it is closed, and extends along the width direction, continuously from the lower end of the left frame portion 22 and the lower end of the right frame portion 23.

[0032] Figure 4 is a schematic diagram illustrating the groove 4 and second packing 5 of the soundproof door 1 in cross-section. In Figure 4, the door body 6 in the closed state is shown in a lower cross-section viewed from the door edge side toward the hinge side.

[0033] As shown in the figure, the groove 4 is embedded in the floor surface 8 and is formed in a concave or substantially U-shaped cross-section that opens upward toward 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 (for example, a rubber packing) and contains a magnetic material 52 and is elastically deformable. The magnetic material 52 provided in the second packing 5 is preferably a magnetic plate-shaped member or sheet-shaped member and is integrally attached to the upper inner circumference of the hollow portion 51 of the second packing 5.

[0034] As shown in Figure 4, the second packing 5 is housed within the groove 4 and is arranged in a flexible shape with its upper part recessed below the groove 4. The magnetic material 52 inside the second packing 5 is also arranged in a similar flexible shape. The second packing 5 as a whole is immersed in the groove 4 and is arranged without protruding above the groove 4 or the floor surface 8.

[0035] The door body 6 is provided with an adsorption member 65 that magnetically attracts the second packing 5, which is provided in this manner. The adsorption member 65 is a magnetic strip-shaped member. As shown in Figure 2, the adsorption member 65 is arranged continuously 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 Figure 4, a storage space 63 for accommodating the suction member 65 is provided in the lower edge 62 of the door body 6. The storage space 63 is formed along the width direction of the door body 6. In the exemplary embodiment, the storage space 63 is provided in a concave shape that opens downwards, and a recess 64 is formed in the lower edge 62 of the door body 6. When the door body 6 is closed, the first packing 31 of the door stop 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 without any gaps.

[0037] The suction member 65 is provided so as to be able to move vertically between the lower end position of the storage space 63 of the door body 6 and a retracted position above the lower end position. In Figure 4, the suction member 65 is in the retracted position and is positioned in contact with the ceiling surface of the storage space 63. In the example embodiment, the ceiling surface of the storage space 63 is formed in a curved shape that bulges upward, and the suction member 65 also has a curved shape that conforms to the inner surface of the storage space 63.

[0038] As shown in Figure 2, the lever handle 7 provided on the door body 6 is equipped with a pivot shaft 71. The lever handle 7 is rotatably operated around the pivot shaft 71. Furthermore, the lever handle 7 is capable of controlling the vertical displacement of the suction member 65. The pivot shaft 71 of the lever handle 7 is connected to an operating mechanism 72 built into the door body 6, and a rod 73 extends downward from the operating mechanism 72. The suction member 65 is attached to the lower end of the rod 73.

[0039] The operating mechanism 72, connected to the pivot shaft 71 of the lever handle 7, moves the rod 73 up and down when the lever handle 7 is rotated. The suction member 65 is provided on the door body 6 so as to be able to move up and down when the lever handle 7 is rotated.

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

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

[0042] The second packing 5 changes shape and expands at the upper inner circumference of the hollow portion 51, and together with the magnetic material 52, it protrudes from the groove portion 4. The second packing 5 elastically deforms and adheres tightly to the suction member 65 at its lower end. The magnetic material 52 makes surface contact with the suction member 65 via the upper inner circumference of the protruding second packing 5. In addition, the second packing 5 adheres tightly to the magnetic first packing 31 provided on the door stop portion 3 due to the magnetic force of the magnetic material 52. The recess 64 of the door body 6 is blocked by the second packing 5 that protrudes upward from the groove portion 4.

[0043] As described above, the second packing 5 is embedded in the floor surface 8 and is also designed to extend and retract freely by the vertical displacement of the suction member 65. The space between the door body 6 and the floor surface 8 can be sealed without any gaps by the bulging second packing 5. In addition, the iron plate 61 of the door body 6 is in close contact with the first packing 31 of the door stop 3, and the bulging second packing 5 is also in close contact with the first packing 31 of the door stop 3, thereby sealing the space between the door body 6 and the frame 2. As a result, the door body 6 can be sealed without any gaps to both the frame 2 and the floor surface 8, preventing sound leakage and improving sound insulation performance.

[0044] When the lever handle 7 is rotated downward from the state shown in Figure 5, the rod 73 is pulled upward. The suction member 65 rises together with the rod 73 and is displaced to a retracted position within the housing space 63, as shown in Figure 6. In the retracted position, the second packing 5 detaches from the suction member 65, changes shape together with the magnetic material 52, and becomes re-embedded in the groove 4.

[0045] When the second packing 5 is retracted into the groove 4 below the door body 6, there are no protrusions on the floor surface 8. Therefore, when walking through the open soundproof door 1, the risk of tripping is reduced, improving ease of walking.

[0046] Furthermore, the lever handle 7 used to operate the suction 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 suction member 65. This further enhances the operability of the soundproof door 1.

[0047] As described above, the soundproof door 1 according to this embodiment is equipped with a second packing 5 that is embedded in the floor surface 8 and can be extended and retracted, and an adsorption member 65 that attracts the second packing 5 by magnetic force. When the door body 6 is open, the second packing 5 can be retracted into the floor surface 8, so that it does not protrude above the floor, making the floor surface 8 barrier-free. When the door body 6 is closed, three sides are sealed by the close contact between the iron plate 61 of the door body 6 and the magnetic first packing 31, and the space between the door body 6 and the floor surface 8 is sealed without gaps by the bulging second packing 5, and also sealed by the close contact between the second packing 5 and the first packing 31. As a result, all four sides of the door body 6 are sealed without gaps, ensuring airtight continuity and significantly improving sound insulation and soundproofing.

[0048] In addition, in the soundproof door 1, the first packing 31 is not limited to being made of magnetic rubber, but may be configured in any way as long as it is a magnetic packing. Also, in the door body 6, the magnetic member provided in the part that the door stop 3 abuts is not limited to an iron plate 61, but may be configured in any way as long as it is a magnetic member, and may be a magnetic flat plate or sheet-shaped member, such as a magnetic sheet.

[0049] Similarly, the second packing 5 is not limited to the configuration described above, and can be configured in any way as long as it is a magnetic packing containing a magnetic material and elastically deformable. For example, the second packing 5 may contain a magnetic material, and powdered magnetic material may be mixed into the packing material and molded, so that the second packing 5 itself has magnetic properties. Also, the magnetic material 52 does not have to be formed integrally with the second packing 5, and may be a separate and independent component from the second packing 5.

[0050] Furthermore, it is desirable that the second packing 5 and the magnetic material 52 have deformation properties that allow them to expand and retract without force, as well as durability that can withstand repeated deformation. In addition, it is preferable that the second packing 5 is replaceable, and that it can be replaced with a new one as appropriate depending on the period of use.

[0051] This disclosure is not limited to the embodiments described above, and various modifications are possible without departing from the technical essence thereof. All technical matters included in the technical idea described in the claims are subject to this disclosure. The embodiments described above are preferred examples, but various modifications can be realized from the disclosed content, and such modifications are also included in the technical scope described in the claims.
