[0029] [First embodiment] A sliding door structure according to a first embodiment of the present invention will be described below with reference to Figures 1 to 8. As shown in Figure 1, the sliding door structure according to this embodiment includes a sliding door 7 and a door pocket 8 provided between a floor surface F and a ceiling C. In the sliding door structure according to this embodiment, the front side of the paper in Figure 1 (the upper side in Figure 2 and the left side in Figures 3 and 4) is defined as the front of the sliding door 7.

[0030] 2 to 4, the sliding door structure is formed to be symmetrical in the front-to-rear direction of the sliding door 7. As shown in Fig. 1, the sliding door structure includes a baseboard member 1 provided on a floor surface F and a top rail 2 provided on a ceiling C. The baseboard member 1 supports a bottom frame 81 that constitutes a door pocket 8.

[0031] As shown in Figures 1, 3 and 4, an upper frame 4 is fixed to the top rail 2. The upper frame 4 holds the upper ends of the door pocket glass plates 82, 82 that constitute the door pocket 8. In this embodiment, the door pocket glass plate 82 has a double structure in which two glass plates 82a, 82a are stacked on top of each other. As shown in Figures 3 and 4, a rail 6 for the sliding door 7 is provided on the underside of the upper frame 4. In this way, the rail 6 is provided on the ceiling C via the top rail 2 and the upper frame 4.

[0032] In the sliding door structure according to this embodiment, the sliding door 7 slides along the rails 6 and advances and retreats from the door pocket 8, thereby opening and closing the sliding door 7. In this embodiment, a state in which the sliding door 7 slides leftward in Fig. 1 and is extended from the door pocket 8 is described as a "closed state" of the sliding door 7, and a state in which the sliding door 7 slides rightward in Fig. 1 and is contained in the door pocket 8 is described as an "open state" of the sliding door 7.

[0033] 1 and 3, the upper frame 4 is provided with a cover portion 5 for covering a hanging support member 72 (described later) and the upper end portion of the sliding door 7 when the sliding door 7 is in a closed state. In this embodiment, the cover portion 5 is configured as a separate member from the rail 6, but the cover portion 5 and the rail 6 can also be configured as an integral part.

[0034] As shown in FIG. 3, in this embodiment, the cover portion 5 accommodates the upper end of the sliding door 7 in the closed state. A first top seal member 51f is provided on the front side of the inner peripheral surface of the cover portion 5, and a second top seal member 51r is provided on the rear side. When the sliding door 7 is in the closed state, the tip portions of the first top seal member 51f and the second top seal member 51r abut against the sliding door main body 73, thereby blocking the gap between the upper end of the sliding door 7 and the inner peripheral surface of the cover portion 5. In this way, in this embodiment, the sealing performance between the cover portion 5 and the upper end of the sliding door 7 is improved. The seal member described in this specification is made of an elastically deformable soft resin.

[0035] The sliding door 7 is suspended from a rail 6 so as to be able to be opened and closed. In the sliding door 7, a suspension member 72 is fixed to the upper surface of a steel sliding door main body 73, and rollers 71, 71 are provided extending upward from the suspension member 72. The rollers 71, 71 are rollably housed inside the rail 6 so as to allow the sliding door 7 to slide along the rail 6.

[0036] 1 and 2, a door end frame 3 is provided on the door end side of the sliding door 7. The door end frame 3 functions as a door stop when the sliding door 7 is closed. A first panel P1 is provided on the door end frame 3 on the opposite side to the sliding door 7.

[0037] 1 and 7, a sliding door closer 93, which is a self-closing means, is provided on the upper side of the sliding door 7 near the door end frame 3. A wire 93a can advance and retreat from the sliding door closer 93. The wire 93a extending from the sliding door closer 93 is wound up on the sliding door closer 93 by the elastic force of a coil spring provided in the sliding door closer 93.

[0038] As shown in Fig. 5(a) and (b), a leading end support member 74 is provided at the leading end of the sliding door main body 73. A sliding door seal member 76 is provided at the leading end support member 74. As shown in Fig. 6(a) and (b), a trailing end support member 78 is provided at the trailing end of the sliding door main body 73. A first trailing end seal member 79f and a second trailing end seal member 79r are provided at the trailing end support member 78. As shown in Fig. 3 and Fig. 4, a guided member 75 that opens downward in a groove shape is provided at the lower end of the sliding door main body 73. A handle 91 and a key 92 are attached near the leading end of the sliding door main body 73.

[0039] The door pocket 8 is a panel member that houses the sliding door 7 in an open state. Specifically, as shown in Figures 1, 2, and 4, the door pocket 8 includes an upper frame 4 fixed to the top rail 2, a tail frame 80 provided on the side of the door pocket 8 on the open side, a frame member 83 provided on the side of the door pocket 8 on the closed side, and a lower frame 81, which is a door pocket bottom frame, fixed to the baseboard member 1. A rectangular door pocket glass plate 82 (glass plates 82a-82a) is held at its outer periphery on each of the front and rear sides of the door pocket 8 by the upper frame 4, tail frame 80, frame member 83, and lower frame 81.

[0040] In this way, the door pocket 8 is configured with so-called double glass, in which a pair of door pocket glass plates 82, 82 are arranged adjacent to both sides in the thickness direction of the sliding door 7 in the open state and parallel to the sliding door 7. A second panel P2 is provided on the frame member 83 on the opposite side to the sliding door 7.

[0041] 2, 4 and 6, the aluminum glass pressing parts constituting the outer surface parts of the tail edge frame 80, the bottom frame 81 and the frame member 83 are configured to be detachable. Then, the door pocket glass plate 82 is set in the tail edge frame 80, the bottom frame 81 and the frame member 83 from which the glass pressing frames have been removed, and the door pocket glass plate 82 is fixed to the tail edge frame 80, the bottom frame 81 and the frame member 83 by fitting the glass pressing frames into place.

[0042] In addition, in the sliding door structure, it is also possible to configure the sliding door 7 in the open state not to be housed in the door pocket 8. Specifically, it is also possible to configure the sliding door 7 in the open state to have a panel member (such as the door pocket glass plate 82) disposed parallel to the sliding door 7, adjacent to only one side in the thickness direction of the sliding door 7 in the open state. In this case, the surface of the sliding door 7 that does not face the door pocket glass plate 82 is exposed to the outside when the sliding door 7 is in the open state.

[0043] 3 and 4, a bottom seal member 77 is provided at the bottom end of the sliding door main body 73, which closes the gap between the bottom end of the sliding door 7 and the floor F when the sliding door 7 is closed. The bottom seal member 77 always abuts against the floor F, thereby closing the gap between the floor F and the bottom end of the sliding door 7, preventing sound and light leakage below the sliding door 7. It is also possible to configure the bottom seal member 77 to be separated from the floor F when the sliding door 7 is open, and to automatically move downward when the sliding door 7 is closed, closing the gap between the sliding door 7 and the floor F.

[0044] 2 and 4, a guide unit 84 is provided below the sliding door 7 on the floor surface F, more specifically near the door tip side of the door end frame 80. Two guide rollers 86 are provided on the guide unit 84 via roller support parts 85. That is, the guide rollers 86 are fixed to the floor surface F via the roller support parts 85.

[0045] 4, a guide roller 86 is disposed inside a guided member 75 of the sliding door 7. When the sliding door 7 slides in the sliding door structure, the guide roller 86 rolls along the inner surface of the guided member 75. In this way, the sliding door 7 is guided by the guide rollers 86 when the sliding door 7 opens and closes.

[0046] 2 and 8, a stopper 88 is provided on the lower end of the frame member 83 toward the inside of the door pocket 8. The stopper 88 restricts the displacement of the sliding door 7 by abutting against the trailing end of the sliding door 7 when the sliding door 7 is opened. In this embodiment, the stopper 88 is disposed between the lower frames 81 to make the stopper 88 less visible from the outside, thereby improving the appearance of the sliding door structure.

[0047] 6(a) and (b), a brush 87 is provided on the inner surface of the tail frame 80 along the vertical direction, which is the longitudinal direction of the tail frame 80. The brush 87 prevents insects and the like from entering the inside of the door pocket 8 through the gap with the sliding door main body 73. In this embodiment, the brush 87 is made of a bundle of fibrous material such as chemical fiber or natural fiber.

[0048] 7(a) and (b), the tip of the wire 93a is locked to a locked portion 72a formed on the hanging support member 72. The sliding door 7 in the open state is closed by being pulled by the sliding door closer 93 via the wire 93a. That is, in this embodiment, the sliding door 7 is configured to be automatically closed by the sliding door closer 93. It is also possible to configure the sliding door structure without providing the sliding door closer 93.

[0049] 2 and 5(b), when the sliding door 7 is in a closed state, the door leading end of the sliding door 7 abuts against the door leading frame 3. A recess 31 is formed on the surface of the door leading frame 3 facing the door leading end of the sliding door 7 to accommodate the door leading end when the sliding door 7 is in a closed state.

[0050] 5(a) and 5(b), the recess 31 includes a first inner side surface 32f and a second inner side surface 32r that are arranged parallel to each other and face each other, and an abutment surface 33 that is continuous and substantially perpendicular to the first inner side surface 32f and the second inner side surface 32r. When the sliding door 7 is in a closed state, the door-front end portion of the sliding door 7 (specifically, the door-front support member 74 as shown in FIG. 5(b)) is disposed between the first inner side surface 32f and the second inner side surface 32r, and is accommodated in the recess 31. At this time, the sliding door seal member 76 abuts against the abutment surface 33.

[0051] The sliding door structure of this embodiment comprises a first door end seal member 34f capable of blocking the gap between the first inner surface 32f and the door end side end when the sliding door 7 is in a closed state, and a second door end seal member 34r capable of blocking the gap between the second inner surface 32r and the door end side end when the sliding door 7 is in a closed state.

[0052] 5(a) and 5(b), the first door end seal member 34f is provided on the first inner surface 32f. When the sliding door 7 is in the closed state, the first door end seal member 34f abuts against a first corner 74f formed on the first inner surface 32f side of the door end support member 74. Similarly, the second door end seal member 34r is provided on the second inner surface 32r. When the sliding door 7 is in the closed state, the second door end seal member 34r abuts against a second corner 74r formed on the second inner surface 32r side of the door end support member 74.

[0053] As described above, according to the sliding door structure of this embodiment, when the sliding door 7 is in the closed state, with the door end tip portion (in this embodiment, the door end support member 74) accommodated in the recess 31 of the door end frame 3, the first door end seal member 34f can close the space between the first inner surface 32f and the door end side end, and the second door end seal member 34r can close the space between the second inner surface 32r and the door end side end.

[0054] In this manner, in this embodiment, when the sliding door 7 is in the closed state, the door tip is accommodated in the recess 31 of the door frame 3, making it difficult for a gap connecting one side of the sliding door 7 to form between the door tip end of the sliding door 7 and the door frame 3, thereby preventing light leakage.

[0055] In addition, in the conventional sliding door structure, it may be difficult to make the door end frame and the door end tip tightly contact over the entire vertical length due to slight distortion of the building itself such as uneven floors and limitations in construction accuracy. On the other hand, in this embodiment, the first and second inner surfaces 32f and 32r arranged parallel to the front and rear surfaces of the sliding door 7 and the door end tip can be closed with the first and second door end seal members 34f and 34r. This makes it possible to suppress the influence of distortion of the building itself and construction accuracy, so that the door end frame 3 and the door end tip can be tightly contacted over the entire vertical length. In this way, the sliding door structure according to this embodiment has a simple configuration, so that the natural opening and closing action of the user can suppress sound leakage between the door end frame 3 and the door end tip, thereby improving sound insulation performance.

[0056] In addition, since the door-leading end of the sliding door 7 is housed in the recess 31 of the door-leading frame 3, it is possible to restrict the displacement of the sliding door 7 in the out-of-plane direction (the up-down direction in FIG. 2). Even if the sliding door 7 is displaced in the out-of-plane direction, the first door-leading seal member 34f and the second door-leading seal member 34r abut against the door-leading end of the sliding door 7, so that rattling of the sliding door 7 can be cushioned.

[0057] In the sliding door structure according to this embodiment, as shown in Fig. 5(b), a clearance is formed between the first inner surface 32f and the second inner surface 32r of the recess 31 and the door-tip end of the sliding door 7. As a result, even if the sliding door 7 suspended by the rail 6 swings in the out-of-plane direction and tilts, the door-tip end can be accommodated in the recess 31, so that the door-tip end can be reliably sealed with a natural opening and closing action. In addition, even if the sliding door 7 is displaced within the range of the clearance between the recess 31 and the door-tip end, at least one of the first door-tip seal member 34f and the second door-tip seal member 34r is set to abut against each other, so that the sealing performance of the door-tip end can be maintained.

[0058] In this embodiment, the first door end seal member 34f and the second door end seal member 34r are provided on the inner surfaces (the first inner surface 32f and the second inner surface 32r) of the recess 31 of the door end frame 3. This makes the first door end seal member 34f and the second door end seal member 34r less visible from the outside, improving the appearance of the sliding door 7, compared to a configuration in which the first door end seal member 34f and the second door end seal member 34r are provided on the door end side end of the sliding door 7.

[0059] 5(a), the first door end seal member 34f and the second door end seal member 34r are arranged so that, in a natural state (a state in which no external force is applied), their tips are inclined in a direction approaching the contact surface 33. In other words, the first door end seal member 34f and the second door end seal member 34r are arranged so that their tips face the depth direction of the recessed portion 31.

[0060] The first door end seal member 34f and the second door end seal member 34r are then abutted against the first corner portion 74f and the second corner portion 74r formed in the door end side support member 74 to provide a seal. At this time, since the first door end seal member 34f and the second door end seal member 34r are inclined in advance, it is possible to reduce the amount of deformation of the first door end seal member 34f and the second door end seal member 34r when they abut against the first corner portion 74f and the second corner portion 74r as shown in FIG. 5(b).

[0061] In detail, as shown in Fig. 5(b), the first and second door end seal members 34f, 34r are attached to the door end frame 3 so as to be slightly rotatable. The first and second door end seal members 34f, 34r are formed in an L-shape in the initial state, and rotate slightly in the direction of escape when they come into contact with the first and second corners 74f, 74r. In addition, the first and second door end seal members 34f, 34r are formed with notches as deformation allowance portions so as to be able to deform further after they come into contact with the first and second corners 74f, 74r.

[0062] In this embodiment, by being configured as described above, the resistance force that the door end frame 3 applies to the sliding door 7 when the first and second door end seal members 34f and 34r abut against the first and second corner portions 74f and 74r is reduced. Moreover, in this embodiment, the resistance force that the door end frame 3 applies to the sliding door 7 is also suppressed by having the first and second door end seal members 34f and 34r abut against the first and second corner portions 74f and 74r. Moreover, in order to prevent the first and second door end seal members 34f and 34r from acting as a brake on the closing operation of the sliding door 7, the first and second door end seal members 34f and 34r are set to abut against the first and second corner portions 74f and 74r at the rearmost part of the stroke of the closing operation of the sliding door 7.

[0063] In this embodiment, by configuring as described above, when closing the sliding door 7, a high level of sealing can be ensured between the door end frame 3 and the door end side end, regardless of whether the user is manually operating the sliding door 7. That is, since the first door end seal member 34f and the second door end seal member 34r in an inclined state are abutted against the first corner portion 74f and the second corner portion 74r formed on the door end side end to effect sealing with a natural movement, the user does not need to apply force to the sliding door 7 to push it toward the door end frame 3.

[0064] As described above, in this embodiment, the sliding door 7 is configured to be automatically closed by the sliding door closer 93. In this way, even when the sliding door 7 closes automatically by the sliding door closer 93, the first door end seal member 34f and the second door end seal member 34r in the inclined state come into contact with the first corner portion 74f and the second corner portion 74r formed at the door end side end. In other words, even when the sliding door 7 closes automatically, it is possible to improve the sealing performance between the door end frame 3 and the door end side.

[0065] Furthermore, by abutting the inclined first door end seal member 34f and the second door end seal member 34r against the first corner portion 74f and the second corner portion 74r formed at the door end side end and sealing with the deformation amount of the first door end seal member 34f and the second door end seal member 34r reduced, it is possible to suppress the frictional force when opening the sliding door 7. Therefore, the user does not need to apply a large force to the sliding door 7 when opening it.

[0066] As shown in Figures 6(a) and (b), in the sliding door structure according to this embodiment, a tail frame 80 that holds a door pocket glass plate 82 in a door pocket 8 protrudes toward the sliding door 7 beyond the inner surface of the door pocket glass plate 82. In other words, the door pocket 8, which is a panel member, is provided with a protruding portion of the tail frame 80 that protrudes toward the inside of the door pocket 8. The tail frame 80 is close to the tail side end of the sliding door 7 in the closed state. As shown in Figure 6(a), in this embodiment, the protruding portion of the tail frame 80 is formed on a part of the inner surface of the door pocket 8.

[0067] The sliding door structure of this embodiment is provided with a first trailing edge seal member 79f and a second trailing edge seal member 79r that can seal the gap between the trailing edge end portion of the sliding door 7 (in this embodiment, the trailing edge support member 78) and the protrusion of the trailing edge frame 80 when the sliding door 7 is in a closed state.

[0068] 6(a) and 6(b), the first trailing edge seal member 79f is provided on the front side of the trailing edge support member 78. When the sliding door 7 is in the closed state, the first trailing edge seal member 79f comes into contact with a trailing edge frame corner portion 80a at a convex portion formed at the rear of the front trailing edge frame 80. Similarly, the second trailing edge seal member 79r is provided on the rear side of the trailing edge support member 78. When the sliding door 7 is in the closed state, the second trailing edge seal member 79r comes into contact with a trailing edge frame corner portion 80a at a convex portion formed at the front of the rear trailing edge frame 80.

[0069] As described above, according to the sliding door structure of this embodiment, the first trailing edge seal member 79f and the second trailing edge seal member 79r can close the gap between the trailing edge frame 80·80 and the trailing edge end of the sliding door 7 when the sliding door 7 is in the closed state. That is, the gap between the trailing edge end of the sliding door 7 and the trailing edge frame 80·80 is closed, and it is possible to improve the sealing performance between the trailing edge frame 80·80 and the trailing edge with a simple structure.

[0070] In this embodiment, when the sliding door 7 is in the closed state, the first door end seal member 79f and the second door end seal member 79r are capable of blocking the space between the protrusion on the inner surface of the door pocket 8 and the door end side end, thereby improving the sealing performance between the door pocket 8 and the door end side end.

[0071] As shown in Figure 6(a), the first door end seal member 79f and the second door end seal member 79r are arranged so that in their natural state (when no external force is applied), their tip portions are inclined in a direction away from the door end frames 80 / 80.

[0072] The first and second trailing edge seal members 79f and 79r are then brought into contact with the trailing edge frame corners 80a formed in the trailing edge frames 80 to provide a seal. Since the first and second trailing edge seal members 79f and 79r are inclined in advance, the amount of deformation of the first and second trailing edge seal members 79f and 79r when they come into contact with the trailing edge frame corners 80a can be reduced as shown in FIG. 6(b).

[0073] In detail, the first and second trailing edge seal members 79f and 79r are attached to the trailing edge support member 78 so as to be slightly rotatable, as shown in Fig. 6(b). The first and second trailing edge seal members 79f and 79r are initially formed in a dogleg shape, and rotate slightly in the direction of escape when they come into contact with the trailing edge frame corners 80a. The first and second trailing edge seal members 79f and 79r are formed with a notch as a deformation permitting portion so as to be further deformable after they come into contact with the trailing edge frame corners 80a.

[0074] In this embodiment, the above-mentioned configuration reduces the resistance force that the door end frame 3 applies to the sliding door 7 when the first and second end seal members 79f and 79r come into contact with the end frame corners 80a and 80a. Moreover, in this embodiment, the first and second end seal members 34f and 34 are brought into contact with the first and second corners 74f and 74r, thereby suppressing the resistance force that the end frame 80 applies to the sliding door 7. Moreover, in order to prevent the first and second end seal members 79f and 79r from acting as a brake on the closing operation of the sliding door 7, the first and second end seal members 79f and 79r are set to come into contact with the end frame corners 80a and 80a at the rearmost part of the stroke of the closing operation of the sliding door 7.

[0075] In this embodiment, by configuring as described above, when closing the sliding door 7, high sealing performance can be ensured between the tail frame 80·80 and the tail side end, regardless of whether the user is manually operating the sliding door 7. That is, since the first tail seal member 79f and the second tail seal member 79r in an inclined state are abutted against the tail frame corners 80a·80a formed on the tail frame 80·80 to provide a seal, the user does not need to apply force to the sliding door 7 to push it between the tail frame 80·80.

[0076] Furthermore, by abutting the inclined first trailing edge seal member 79f and the second trailing edge seal member 79r against the trailing edge frame corners 80a formed on the trailing edge frames 80, sealing is performed with the deformation of the first trailing edge seal member 79f and the second trailing edge seal member 79r reduced, thereby reducing frictional force when opening the sliding door 7. Therefore, the user does not need to apply a large force to the sliding door 7 when opening it.

[0077] In this embodiment, as shown in Fig. 6(a), when the sliding door 7 is moving to open or close, a gap is formed between the first and second end seal members 79f and 79r and the side surface of the door pocket glass plate 82. If there is no sufficient gap between the first and second end seal members 79f and 79r and the side surface of the door pocket glass plate 82, the air flow during the opening and closing operation of the sliding door 7 becomes poor, and a large force is required for the opening and closing operation. In this embodiment, by forming a sufficient gap between the first and second end seal members 79f and 79r and the side surface of the door pocket glass plate 82, the air flow during the opening and closing operation of the sliding door 7 is smoothed, and the force required for the opening and closing operation is reduced.

[0078] As described above, the door pocket 8 in this embodiment is composed of a pair of door pocket glass plates 82, 82 arranged at positions sandwiching the sliding door 7 in the open state. The protruding portions with which the first and second door end seal members 79f and 79r abut are formed as door end frame corners 80a, 80a, which are part of the door end frame 80 that holds the door pocket glass plate 82. In this manner, in this embodiment, the protruding portions with which the first and second door end seal members 79f and 79r abut are configured as part of the door end frame 80 that holds the door pocket glass plate 82. This eliminates the need to separately form protruding portions for abutting the first and second door end seal members 79f and 79r, thereby reducing the number of parts that constitute the sliding door structure.

[0079] As described above, in the sliding door structure according to this embodiment, when the sliding door 7 is in a closed state, the first door end seal member 34f and the second door end seal member 34r can close the gap between the recess 31 of the door end frame 3 and the door end side end of the sliding door 7, the first door tail seal member 79f and the second door tail seal member 79r can close the gap between the protrusion of the door tail frame 80 and the door tail side end of the sliding door 7, the first top seal member 51f and the second top seal member 51r close the gap between the inner circumferential surface of the cover portion 5 and the upper end of the sliding door 7, and the bottom seal member 77 closes the gap between the floor surface F and the lower end of the sliding door 7. In this way, in the sliding door structure according to this embodiment, by configuring all four sides of the sliding door 7 to be sealed with each seal member, it is possible to maintain a higher sealability of the sliding door structure when the sliding door 7 is in a closed state.

[0080] [Second embodiment] Next, a sliding door structure according to a second embodiment of the present invention will be described with reference to Fig. 9 to Fig. 12. As shown in Fig. 9, the sliding door structure according to this embodiment includes a sliding door 107 and a door pocket 108 provided between a floor surface F and a ceiling C. In the sliding door structure according to this embodiment, the front side of the paper in Fig. 9 (the upper side in Fig. 10 and the left side in Fig. 11) is defined as the front of the sliding door 107.

[0081] 10 and 11, the sliding door structure is formed to be symmetrical in the front-rear direction of the sliding door 107. As shown in Fig. 9, the sliding door structure includes a baseboard member 101 provided on a floor surface F, and a top rail 102 provided on a ceiling C. The baseboard member 101 supports a bottom frame 181 that constitutes a door pocket 108.

[0082] As shown in Figures 9 and 11, an upper frame 104 is fixed to the top rail 102. The upper frame 104 holds the upper ends of door pocket glass plates 182, which constitute a door pocket 108. In this embodiment, the door pocket glass plate 182 has a double structure in which two glass plates 182a, 182a are stacked on top of each other. As shown in Figure 11, a rail 106 for a sliding door 107 is provided on the underside of the upper frame 104. In this way, the rail 106 is provided on the ceiling C via the top rail 102 and upper frame 104.

[0083] In the sliding door structure according to this embodiment, the sliding door 107 slides along rails 106 and advances and retreats from a door pocket 108, thereby opening and closing the sliding door 107. In this embodiment, a state in which the sliding door 107 slides leftward in FIG. 9 and is extended from the door pocket 108 is described as a "closed state" of the sliding door 107, and a state in which the sliding door 107 slides rightward in FIG. 9 and is housed in the door pocket 108 is described as an "open state" of the sliding door 107.

[0084] 11, the upper frame 104 is provided with a cover portion 105 for covering a hanging support member 172 and an upper frame member 174c (described later) when the sliding door 107 is in a closed state. In this embodiment, the cover portion 105 is configured as a separate member from the rail 106, but the cover portion 105 and the rail 106 can also be configured as an integral part.

[0085] The sliding door 107 is suspended from a rail 106 and can be opened and closed. Specifically, as shown in Fig. 10 and Fig. 11, the sliding door 107 includes a door-leading side frame member 174a provided on the side of the door leading side, a door-ending side frame member 174b provided on the side of the door trailing side, an upper side frame member 174c provided on the upper part, and a lower side frame member 174d provided on the lower part.

[0086] The two door glass panels 173-173, which are rectangular surface materials, are held at their outer peripheries by these frame members 174a-174d. In this manner, the sliding door 107 is equipped with the door glass panels 173-173, and is configured as a so-called double glass. It is also possible for the sliding door 107 to be configured with the door glass panel 173 made of a single glass. In other words, the sliding door 107 can be equipped with one or more door glass panels 173.

[0087] 11 , a hanging support member 172 is fixed to the upper surface of 174c of the sliding door 107, and rollers 171 are provided extending upward from the hanging support member 172. The rollers 171 are rollably housed inside the rail 106, thereby allowing the sliding door 107 to slide along the rail 106.

[0088] As shown in FIG. 11, in this embodiment, the cover portion 105 accommodates the upper end of the sliding door 107 in the closed state. On the inner peripheral surface of the cover portion 105, a first top seal member 151f is provided on the front side, and a second top seal member 151r is provided on the rear side. When the sliding door 107 is in the closed state, the tip portions of the first top seal member 151f and the second top seal member 151r abut against the upper support frame 174c that holds the door glass plates 173·173, thereby blocking the gap between the upper end of the sliding door 107 and the inner peripheral surface of the cover portion 105. In this way, in this embodiment, the sealability between the cover portion 105 and the upper end of the sliding door 107 is improved.

[0089] As shown in Figures 9 and 10, a door end frame 103 is provided on the door end side of the sliding door 107. The door end frame 103 functions as a door stop when the sliding door 107 is closed. A panel P is provided on the opposite side of the door end frame 103 to the sliding door 107. As shown in Figure 9, a sliding door closer 193, which is an automatic closing means, is provided on the upper side of the sliding door 107 near the door end frame 103, as in the first embodiment.

[0090] As shown in Figures 12(a) and (b), a sliding door seal member 176 is provided on the door-end frame member 174a of the sliding door 107. Also, as shown in Figure 10, a first door-end seal member 179f and a second door-end seal member 179r are provided on the door-end frame member 174b of the sliding door 107. Also, as shown in Figure 11, a guided member 175 that opens downward in a groove shape is provided on the lower frame member 174d. Also, a handle 191 and a key 192 are attached near the door end of the sliding door 107.

[0091] The door pocket 108 is a panel member that houses the sliding door 107 in an open state. Specifically, as shown in Figures 9 and 10, the door pocket 108 includes an upper frame 104 fixed to the top rail 102, a tail frame 180 provided on the side of the open side of the door pocket 108, and a lower frame 181, which is a door pocket bottom frame, fixed to the baseboard member 101. A rectangular door pocket glass plate 182 (glass plates 182a-182a) is held at the outer periphery on each of the front and rear sides of the door pocket 108 by the upper frame 104, tail frame 180, and lower frame 181.

[0092] In this way, the door pocket 108 is configured with so-called double glass, in which a pair of door pocket glass plates 182-182 are arranged adjacent to both sides of the sliding door 107 in the thickness direction when the door pocket 107 is in the open state and parallel to the sliding door 107. In this embodiment, as shown in Figures 9 and 10, a double glass panel G-G including a pair of front and back glass plates continuous with the door pocket 108 is provided on the side of the door pocket 108 opposite the sliding door 107 in the closed state. The small edges of the door pocket glass plates 182-182 that constitute the door pocket 108 and the glass plates of the double glass panel G-G are connected with joint members J-J.

[0093] In addition, there is no support between the door pocket 108 and the double glass panel G·G, and the space sandwiched between the pair of door pocket glass plates 182·182 on the front and back of the door pocket 108 and the space sandwiched between the pair of glass plates on the front and back of the double glass panel G·G are configured to be continuous.

[0094] In this embodiment, as described above, the door pocket glass plate 182 constituting the door pocket 108 and the glass plates constituting the double glass panel G are connected by joint members J. This allows the door pocket 108 and the double glass panel G to be configured with high continuity without the need for supports, as shown in Fig. 9, making it possible to improve the appearance of the sliding door structure.

[0095] In this embodiment, a double-sided tape such as acrylic foam is used as the joint member J. Other configurations such as a caulking material can also be used for the joint member J. It is also possible to construct the joint member J by assembling joint parts to each of the small edges of the door pocket glass plate 182 that constitutes the door pocket 108 and the glass plates that constitute the double glass panel G, and then connecting these joint parts to each other.

[0096] In the sliding door structure according to this embodiment, it is also possible to configure the sliding door 107 in the open state not to be housed in the door pocket 108. That is, it is also possible to configure the sliding door 107 in the open state to have a panel member (door pocket glass plate 182, etc.) disposed parallel to the sliding door 107 adjacent to only one side in the thickness direction of the sliding door 107.

[0097] 10, when the sliding door 107 is in the closed state, the first end seal member 179f comes into contact with a rear corner (convex portion) of the front end frame 180. Similarly, when the sliding door 107 is in the closed state, the second end seal member 179r comes into contact with a front corner (convex portion) of the rear end frame 180.

[0098] As described above, in the sliding door structure according to this embodiment, the gap between the trailing edge frames 180·180 and the trailing edge of the sliding door 107 can be blocked by the first trailing edge seal member 179f and the second trailing edge seal member 179r when the sliding door 107 is in the closed state. In other words, the gap between the trailing edge of the sliding door 107 and the trailing edge frames 180·180 is blocked, and it is possible to improve the sealing performance between the trailing edge frames 180·180 and the trailing edge of the sliding door 107 with a simple structure.

[0099] 11, a bottom seal member 177 is provided on the lower frame member 174d to close the gap between the lower end of the sliding door 107 and the floor surface F when the sliding door 107 is in a closed state. The bottom seal member 177 is always in contact with the floor surface F to close the gap between the floor surface F and the lower end of the sliding door 107, thereby preventing sound and light leakage below the sliding door 107.

[0100] 10, a guide unit 184 is provided below the sliding door 107 on the floor surface F, more specifically near the door tip side of the door end frame 180. Two guide rollers 186 are provided on the guide unit 184 via roller support parts 185. When the sliding door 107 opens and closes, the sliding door 107 is guided by the guide rollers 186.

[0101] 10, a stopper 188 is provided at the bottom of the door pocket 108 facing the inside of the door pocket 108. The stopper 188 restricts the displacement of the sliding door 107 by abutting against the trailing end of the sliding door 107 when the sliding door 107 is opened. In this embodiment as well, the stopper 188 is disposed between the lower frame 181 to make the stopper 188 less visible from the outside, thereby improving the appearance of the sliding door structure.

[0102] 10 and 12(b), when the sliding door 107 is in a closed state, the door leading end of the sliding door 107 abuts against the door leading frame 103. A recess 131 that accommodates the door leading end of the sliding door 107 when the sliding door 107 is in a closed state is formed on the surface of the door leading frame 103 that faces the door leading end of the sliding door 107.

[0103] 12(a) and 12(b), the recess 131 includes a first inner side surface 132f and a second inner side surface 132r that are arranged parallel to each other and face each other, and an abutment surface 133 that is continuous and substantially perpendicular to the first inner side surface 132f and the second inner side surface 132r. When the sliding door 107 is in a closed state, the door-front end portion of the sliding door 107 (specifically, a part of the door-front frame material 174a as shown in FIG. 12(b)) is disposed between the first inner side surface 132f and the second inner side surface 132r, and is accommodated in the recess 131. At this time, the sliding door seal member 176 abuts against the abutment surface 133.

[0104] The sliding door structure of this embodiment comprises a first door end seal member 134f capable of closing the gap between the first inner surface 132f and the door end side end when the sliding door 107 is in a closed state, and a second door end seal member 134r capable of closing the gap between the second inner surface 132r and the door end side end when the sliding door 107 is in a closed state.

[0105] In detail, as shown in Fig. 12(a) and (b), the first door end seal member 134f is provided on the first inner surface 132f. When the sliding door 107 is in the closed state, the first door end seal member 134f abuts against a first corner portion 174f formed on the first inner surface 132f side of the door end frame material 174a. Similarly, the second door end seal member 134r is provided on the second inner surface 132r. When the sliding door 107 is in the closed state, the second door end seal member 134r abuts against a second corner portion 174r formed on the second inner surface 132r side of the door end frame material 174a.

[0106] As described above, according to the sliding door structure of this embodiment, when the sliding door 107 is in the closed state, with the door end tip portion (in this embodiment, a part of the door end side frame material 174a) accommodated in the recess 131 of the door end frame 103, the first door end seal member 134f can close the gap between the first inner surface 132f and the door end side end, and the second door end seal member 134r can close the gap between the second inner surface 132r and the door end side end.

[0107] In this manner, in this embodiment, when the sliding door 107 is in the closed state, the door tip is accommodated in the recess 131 of the door frame 103, making it difficult for a gap connecting one side and the other side of the sliding door 107 to be formed between the door tip end of the sliding door 107 and the door frame 103, thereby preventing light leakage.

[0108] Also in this embodiment, the gap between the first and second inner surfaces 132f and 132r arranged parallel to the front and rear surfaces of the sliding door 107 and the door end can be closed with the first and second door end seal members 134f and 134r. This makes it possible to suppress the influence of distortion of the building itself and construction accuracy, and allows the door end frame 103 and the door end to be tightly attached over the entire vertical length. In this way, the sliding door structure according to this embodiment has a simple configuration, making it possible to improve sound insulation performance by preventing sound leakage between the door end frame 103 and the door end through the natural opening and closing action of the user.

[0109] In addition, since the door-leading end of the sliding door 107 is housed in the recess 131 of the door-leading frame 103, it is possible to restrict the displacement of the sliding door 107 in the out-of-plane direction (the up-down direction in FIG. 10). Even if the sliding door 107 is displaced in the out-of-plane direction, the first door-leading seal member 134f and the second door-leading seal member 134r abut against the door-leading end of the sliding door 107, so that rattling of the sliding door 107 can be cushioned.

[0110] In the sliding door structure according to this embodiment, as shown in FIG. 12(b), a clearance is formed between the first inner surface 132f and the second inner surface 132r of the recess 131 and the door-tip end of the sliding door 107. As a result, even if the sliding door 107 suspended by the rail 106 swings in the out-of-plane direction and tilts, the door-tip end can be accommodated in the recess 131, so that the door-tip end can be reliably sealed with a natural opening and closing action. In addition, even if the sliding door 107 is displaced within the range of the clearance between the recess 131 and the door-tip end, at least one of the first door-tip seal member 134f and the second door-tip seal member 134r is set to abut against each other, so that the sealing performance of the door-tip end can be maintained.

[0111] In this embodiment, the first door end seal member 134f and the second door end seal member 134r are provided on the inner surfaces (first inner surface 132f and second inner surface 132r) of the recess 131 of the door end frame 103. This makes it difficult for the first door end seal member 134f and the second door end seal member 134r to be seen from the outside, improving the appearance of the sliding door 7, compared to a configuration in which the first door end seal member 134f and the second door end seal member 134r are provided on the door end side end of the sliding door 107.

[0112] 12(a), the first door end seal member 134f and the second door end seal member 134r are arranged so that, in a natural state (a state in which no external force is applied), their leading ends are inclined in a direction approaching the abutment surface 133. In other words, the first door end seal member 134f and the second door end seal member 134r are arranged so that their leading ends face the depth direction of the recess 131.

[0113] The first door end seal member 134f and the second door end seal member 134r are abutted against the first corner portion 174f and the second corner portion 174r formed in the door end side frame material 174a to seal. At this time, since the first door end seal member 134f and the second door end seal member 134r are inclined in advance, it is possible to reduce the amount of deformation of the first door end seal member 134f and the second door end seal member 134r when they abut against the first corner portion 174f and the second corner portion 174r as shown in FIG. 12(b).

[0114] In detail, the first and second door end seal members 134f, 134r are attached to the door end frame 103 so as to be slightly rotatable, as shown in Fig. 12(b). The first and second door end seal members 134f, 134r are initially formed in a dogleg shape, and rotate slightly in the direction of escape when they come into contact with the first and second corners 174f, 174r. In addition, the first and second door end seal members 134f, 134r have notches formed therein as deformation-permitting portions so as to be further deformable after they come into contact with the first and second corners 174f, 174r.

[0115] In this embodiment, by configuring as described above, the resistance force that the door end frame 103 applies to the sliding door 107 is reduced when the first and second door end seal members 134f and 134r abut against the first and second corner portions 174f and 174r. Moreover, in this embodiment, the resistance force that the door end frame 103 applies to the sliding door 107 is also suppressed by abutting the first and second door end seal members 134f and 134r against the first and second corner portions 174f and 174r. Moreover, in order to prevent the first and second door end seal members 134f and 134r from acting as a brake on the closing operation of the sliding door 107, the first and second door end seal members 134f and 134r are set to abut against the first and second corner portions 174f and 174r at the rear end of the stroke of the closing operation of the sliding door 107.

[0116] In this embodiment, by configuring as described above, when closing the sliding door 107, a high level of sealing can be ensured between the door end frame 103 and the door end side end, regardless of whether the user is manually operating the sliding door 107. That is, since the first door end seal member 134f and the second door end seal member 134r in an inclined state are abutted against the first corner portion 174f and the second corner portion 174r formed at the door end side end to provide a seal, the user does not need to apply force to the sliding door 107 to push it toward the door end frame 103.

[0117] In this embodiment as well, the sliding door 107 is configured to be automatically closed by the sliding door closer 193. In this way, even when the sliding door 107 closes automatically by the sliding door closer 193, the first door end seal member 134f and the second door end seal member 134r in the inclined state come into contact with the first corner portion 174f and the second corner portion 174r formed at the door end side end. In other words, even when the sliding door 107 closes automatically, the sealing performance between the door end frame 103 and the door end side end can be improved.

[0118] Furthermore, by abutting the inclined first door end seal member 134f and the second door end seal member 134r against the first corner portion 174f and the second corner portion 174r formed at the door end side end and sealing with the deformation amount of the first door end seal member 134f and the second door end seal member 134r reduced, it is possible to suppress the frictional force when opening the sliding door 107. Therefore, the user does not need to apply a large force to the sliding door 107 when opening it.

[0119] As described above, in the sliding door structure according to this embodiment, when the sliding door 107 is in the closed state, the first door end seal member 134f and the second door end seal member 134r can close the gap between the recess 131 of the door end frame 103 and the door end side end of the sliding door 107, the first door end seal member 179f and the second door end seal member 179r can close the gap between the protrusion of the door end frame 180 and the door end side end of the sliding door 107, the first top seal member 151f and the second top seal member 151r close the gap between the inner circumferential surface of the cover portion 105 and the upper end of the sliding door 107, and the bottom seal member 177 closes the gap between the floor surface F and the lower end of the sliding door 107. In this way, in the sliding door structure according to this embodiment, by configuring all four sides of the sliding door 107 to be sealed with each seal member, it is possible to maintain a higher sealability of the sliding door structure when the sliding door 107 is in the closed state.

[0120] [Variations] The above embodiment can be modified as appropriate as shown in the following modified examples. Each modified example described in this specification may be applied in combination with other modified examples to the extent that no contradiction occurs.

[0121] As described in the first and second embodiments, in the sliding door structure according to the present invention, the sliding door can be made of metal such as steel or glass. Even if glass is used for the sliding door, it is also possible to use a single glass structure having a single glass plate, instead of the double glass shown in the sliding door according to the second embodiment.

[0122] In addition, the door pocket in the sliding door structure may be made of metal such as steel, instead of glass as in the first and second embodiments. In addition, in a configuration in which a panel body is arranged around the sliding door structure, the panel body may be made of metal or glass. In a sliding door structure using a glass panel in the door pocket, even when the glass panels are arranged adjacent to each other, it is possible to provide a frame between the glass panel constituting the door pocket and the adjacent glass panel, or to provide no frame between the glass panel and the adjacent glass panel.

[0123] In the sliding door structure, the first door-edge seal member can be provided on either or both of the first inner surface and the door-edge end portion. Similarly, the second door-edge seal member can be provided on either or both of the second inner surface and the door-edge end portion.

[0124] In the sliding door structure, the panel members arranged parallel to the sliding door in the open state may be arranged on both sides of the sliding door to form a door pocket, or may be arranged on only one side of the sliding door.

[0125] In the sliding door structure, it is also possible to configure the door end seal member, the top seal member, and the bottom seal member without providing any of them. In addition, when providing the door end seal member, it is also possible to provide the protrusion with which the door end seal member abuts on the inner peripheral surface of the panel member or the door pocket separately, rather than configuring it as a part of the frame member. In addition, it is also possible to configure the sliding door structure without providing a sliding door closer, which is a self-closing means. [Explanation of symbols]
