Each figure is a conceptual diagram and does not define the dimensions of the detailed structure.

  As shown in FIG. 1, an opening 20 through which a person enters and exits is formed in a structure 2 such as a house or an apartment house. The opening 20 is provided with a door frame 3 having a square frame shape. The door frame 3 includes an upper frame 31 that extends laterally above the opening 20 of the structure 2, and a lower frame 32 that extends laterally below the opening 20 and has a guide rail portion 32m. And two side frames 33 extending in the vertical direction connecting the upper frame 31 and the lower frame 32 and facing each other.

  As shown in FIG. 1, the sliding door 1 is attached to a door frame 3. The sliding door 1 has a vertically long rectangular shape when viewed from the front. The sliding door main body 10 that forms the main body of the sliding door 1 has an upper side 11 that faces the upper frame 31 of the door frame 3, and a lower side 12 that faces the lower frame 32 of the door frame 3 and has the door wheel 6. Each side 13.

  As shown in FIG. 1, the mating sliding door 1 </ b> E is attached to the door frame 3 together with the sliding door 1. The opponent sliding door 1E has a vertically long rectangular shape when viewed from the front. The counterpart sliding door main body 10E that forms the main body of the counterpart sliding door 1E is opposed to the upper side portion 11 facing the upper frame 31 of the door frame 3 and the lower side portion 12 facing the lower frame 32 of the door frame 3 and having the door wheel 6. And two side portions 13 to be used. When the sliding door 1 and the mating sliding door 1E are closed by the fastening lock 36 when they are closed, they cannot slide.

  As shown in FIG. 1, the sliding door body 10 has a door tip 100 and a door butt 102. The door end 100 refers to a portion that becomes a tip when the sliding door body 10 is slid in the direction of the arrow P <b> 2 in the two side portions 13 of the sliding door body 10. The door bottom 102 refers to a portion that becomes the rear end when the sliding door body 10 is slid in the direction of the arrow P2 and closed among the two side portions 13 of the sliding door body 10. Moreover, the other party sliding door main body 10E has the door tip 100x and the door butt 102x. The door end 100x refers to a portion that becomes a tip when the counterpart sliding door main body 10E is slid in the direction of the arrow P2 and closed among the two side portions 13 of the counterpart sliding door main body 10E. The door bottom 102x refers to a portion that becomes the rear end when the mating door main body 10E is slid in the direction of the arrow P2 and closed among the two side portions 13 of the mating door main body 10E.

  FIG. 2 shows a state in which the sliding door body 10 and the mating sliding door body 10E are slid in the closing direction, and the door butt 102 side of the sliding door body 10 and the door butt 102x side of the mating sliding door body 10E are approaching. As shown in FIG. 2, there is a door butt side gap closing means 200 that closes all or part of the door butt side gap 105 between the door butt 102 side x of the mating door main body 10E and the door butt 102 side of the sliding door main body 10. Is provided.

  The door-side gap closing means 200 includes a first door-side gap closing element 210 that is provided at a portion of the sliding door body 10 on the door-side 102 side and is made of a polymer-based elastic material (rubber or resin). The sliding door body 10E is formed of a second door butt side gap closing element 220 which is provided at a portion of the door butt 102x side and is made of a polymer-based elastic material (rubber or resin). As shown in FIG. 3, the first door butt side gap closing element 210 is formed integrally with the base 270 made of a hard polymer material and a polymer material softer than the base 270. And a seal portion 280. The base 270 has an exposed portion 271 that is exposed so as to protrude from the sliding door main body 10 and an insertion portion 272 that is detachably or non-detachably attached to the attachment hole 19 of the sliding door main body 10 by press-fitting. The insertion portion 272 is inserted into the attachment hole 19 and concealed. The insertion portion 272 has a cylindrical hollow chamber 273 and an engaging claw 274 on the outer peripheral portion, and the elastic deformability and thus the press-fitting property to the mounting hole 19 is ensured. The base portion 270 has a rectangular hollow chamber 275, and is more rigid than the seal portion 280, while ensuring elastic deformation and impact mitigation at the time of collision. The seal portion 280 has a ring shape in cross section. Therefore, the seal portion 280 has a circular seal hollow chamber 281 in cross section, which ensures flexible deformation and elastic deformability, and secures a crushing margin in the sliding direction.

  The second door butt side gap closing element 220 is the same as the first door butt side gap closing element 210 in order to reduce the number of parts, and is press-fitted into the mounting hole 19 of the mating sliding door main body 10E as shown in FIG. It is attached detachably or non-detachably. The second door butt side gap closing element 220 includes a base portion 270 made of a hard polymer material and a seal portion 280 made of a polymer material softer than the base portion 270.

  Since the seal part 280 has the seal hollow chamber 281 as described above, the crushing margin of the seal part 280 in the sliding direction (arrow P direction) increases. Therefore, even when the attachment of the sliding door body 10 and the mating sliding door body 10E to the door frame 3 is not necessarily sufficient, the seal portion 280 of the first door butt side gap closing element 210 and the second door butt side gap closing element 220 are provided. The sealing performance in the sealing section 280 is ensured satisfactorily, and sound insulation and light shielding can be improved.

  For the ring-shaped seal portion 280 having the above-described cross section, the dimension in the sliding direction (arrow P direction) of the sliding door body 10 is DA, and the dimension in the direction orthogonal to the sliding direction of the sliding door body 10 (arrow PX direction) is When DB is used, the dimension DA can be secured larger than the dimension DB. For this reason, the size of the crushing margin of the seal portion 280 in the sliding direction (arrow P direction) is ensured, and as a result, it is possible to contribute to enhancing the sealing performance in the door butt side gap 105 and the sound insulation on the door butt 102, 102x side.

  As shown in FIGS. 2 and 4, the sliding door body 10 and the mating sliding door body 10E are slid in the direction in which the sliding door body 10E and the mating sliding door body 10E are closed (arrow P2 direction). , The seal portion 280 of the first door butt side gap closing element 210 and the seal portion 280 of the second door butt side gap closing element 220 approach each other. As shown in FIG. 4, when the sliding door main body 10 is closed to the door frame 3, the door end 100 of the sliding door main body 10 hits the door frame seal 37 provided on the side frame 33 of the door frame 3, and the door frame seal. By elastically deforming 37, the door end side gap 100c of the sliding door body 10 is closed. This ensures sound insulation and light shielding on the door end 100 side. The same applies to the door end 100x of the counterpart sliding door body 10E.

  When the sliding door body 10 and the mating sliding door body 10E are closed, as shown in FIG. 5, the seal portion 280 of the first door butt side gap closing element 210 and the seal portion 280 of the second door butt side gap closing element 220 are These are elastically deformed by being pressed against each other. Thereby, the door butt side gap 105 positioned between the door butt 102x side of the mating sliding door main body 10E and the door butt 102 side of the sliding door main body 10 is satisfactorily closed, and the sealing performance in the door butt side gap 105 is eventually closed. Sound insulation and light shielding on the 102, 102x side are ensured.

  In particular, since both the first door bottom side gap closing element 210 and the second door bottom side gap closing element 220 are provided with seal portions 280 that are easily elastically deformed, the crushing allowance by the seal portion 280 is approximately doubled. In addition, the sealing property is improved, and the sound insulating property and the light shielding property are improved. When the sliding door body 10 and the mating sliding door body 10E are closed, the distance LK (see FIG. 5) between the bases 270 may vary along the height direction of the sliding door body 10. Further, the distance LK may vary due to aging. Even in such a case, according to the present embodiment, the crushing margin (crushing margin in the sliding direction) by the seal portion 280 of the first door butt side gap closing element 210 and the second door butt side gap closing element 220 is good. Therefore, the fluctuation of the distance LK can be dealt with.

  As shown in FIG. 5, the first center line N1 passing through the center of the seal portion 280 of the first door butt side gap closing element 210 along the sliding direction, and the seal portion 280 of the second door butt side gap closing element 220 The second center line N2 passing through the center along the sliding direction is deviated by a predetermined amount ΔN3 in a direction (arrow PX direction) orthogonal to the sliding direction. For this reason, the seal portion 280 can be elastically deformed well not only in the arrow P direction but also in the arrow PX direction. Therefore, the amount of elastic deformation of the seal portion 280 of the first door butt side gap closing element 210 and the amount of elastic deformation of the seal portion 280 of the second door butt side gap closing element 220 are ensured satisfactorily. Can be improved, and sound insulation on the door butt 102, 102x side can be improved.

  As shown in FIG. 6, although the first door butt side gap closing element 210 having the base portion 270 and the seal portion 280 is attached to the door butt 102 side of the sliding door body 10, the mating sliding door body 10E has a door butt 102x side. The second door bottom side gap closing element 220 having the base portion 270 but not the seal portion 280 may be attached. Further, as shown in FIG. 7, the second door bottom side gap closing element 220 having the base 270 and the seal portion 280 is attached to the door bottom 102x side of the mating sliding door main body 10E. You may decide to attach the 1st door bottom side clearance gap closing element 210 which has the base 270 but does not have the seal part 280.

  As shown in FIG. 18, the upper sound insulating member 40 is formed in an upper hard member 401 formed of a hard material such as a metal or a hard resin held in the storage chamber 41 r of the upper case 41, and in the storage chamber 41 r of the upper case 41. The upper soft member 402 is formed of a soft material such as rubber or resin held upward by the upper hard member 401 so as to have flexibility. Note that the upper soft member 402 has a hollow chamber 403 in order to improve the elastic deformation and tight sealability of the upper frame 31 of the door frame 3 with respect to the groove ceiling surface 38c. However, the hollow chamber 403 may be eliminated, and a structure in which a porous body is embedded in the upper soft member 402 may be used, or a solid structure may be used.

  According to the present embodiment, as shown in FIG. 17, the upper spring member 42 is formed of a plate spring that is bent in a meandering manner so as to have a plurality of bent portions 42 m arranged side by side. It extends along the extending direction of the storage chamber 41 r of the case 41, that is, along the upper side portion 11. A plurality of attachment portions 42k are attached to the bending portion 42m. The upper working body 43 is provided at the end of the accommodation chamber 41r of the upper case 41 so as to be movable in the directions of arrows S1 and S2 (the direction along the upper side portion 11 of the sliding door body 10). Here, the distal end portion 42 a of the upper spring member 42 and the upper operating body 43 are in contact with each other, and the protruding upper operation element 46 of the upper operating body 43 is located outside the side portion 13 of the sliding door body 10. It protrudes toward the direction.

  When the sliding door 1 is slid in the direction of the arrow P1 and opened, the upper operator 46 of the upper working body 43 is separated from the side frame 33 of the door frame 3 as shown in FIG. Due to the urging force, the upper operation element 46 protrudes outward (in the direction of the arrow P2) from the side portion 13 of the sliding door body 10 and is exposed. On the other hand, when the sliding door 1 is slid in the direction of the arrow P2 and closed, the upper operation element 46 of the upper operation body 43 abuts on the side frame 33 of the door frame 3 although not shown in the figure. Is pushed in the retracting direction (arrow P1 direction) and retracted into the side portion 13 of the sliding door body 10. Then, the upper operating body 43 moves in the retracting direction (arrow S1 direction), and as a result, the bent portion 42m of the upper spring member 42 is elastically deformed so as to approach a straight shape. As a result, the upper spring member 42 moves the upper hard member 401 and the upper soft member 402 upward (in the direction of arrow U1). Thus, when the sliding door 1 is closed, the upper soft member 402 presses against the groove ceiling surface 38c of the upper frame 31 of the door frame 3 and the upper gap 91 in the upper side portion 11 is, as shown by the phantom line in FIG. It is closed and the sealing property, sound insulation property and light shielding property on the upper side 11 side of the sliding door body 10 are ensured.

  Further, when the sliding door 1 is slid in the opening direction (arrow P1 direction) and opened, the upper operation element 46 of the upper operating body 43 is separated from the side frame 33 of the door frame 3 as shown in FIG. For this reason, the degree to which the upper operating body 43 restrains the upper spring member 42 is reduced, and the upper operating element 46 protrudes outward from the side portion 13 of the sliding door body 10 by the urging force of the upper spring member 42. That is, the upper operation element 46 protrudes from the side portion 13 in the exposure direction (arrow P2 direction). Further, as described above, since the bent portion 42m of the upper spring member 42 is restored to the original shape, the upper spring member 42 moves the upper hard member 401 and the upper soft member 402 downward (in the direction of arrow U2), The upper soft member 402 is separated from the upper frame 31. For this reason, the resistance which opens the sliding door 1 is reduced.

  Further, according to this embodiment, as shown in FIGS. 16 and 17, the lower gap closing means 5 is provided on the lower side 12 side of the sliding door main bodies 10 and 10E. The lower gap closing means 5 has the same mechanism as the upper gap closing means 4 and is upside down. As shown in FIG. 17, the lower gap closing means 5 includes a lower sound insulating member 50 movably provided below the lower side portion 12 (in the direction of arrow D <b> 1), and the lower sound insulating member 50 at the lower side portion. And a lower actuating portion 55 that moves downward (gap closing direction, arrow D1 direction).

  As shown in FIG. 17, the lower operation portion 55 is arranged on the lower side portion 12 of the sliding door 1 and has a lower case 51 (lower base) having a lower accommodating chamber 51r, and as the sliding door 1 is opened. A lower spring member 52 that urges the lower sound insulation member 50 in the direction in which the side gap 92 is formed, and a lower sound insulation member in a direction (arrow D1 direction) in which the lower gap 92 is closed as the sliding door 1 is closed. And a lower operating body 53 for operating 50.

  As shown in FIG. 19, the lower gap closing means 5 is arranged eccentrically in the lower side portion 12 of the sliding door body 10 with respect to the central region in the thickness direction thereof. That is, the center line MD of the lower gap closing means 5 is eccentric by ΔM with respect to the center line MC in the thickness direction of the sliding door body 10. Therefore, the rollable door pulley 6 is attached to the lower side portion 12 of the sliding door body 10 via the support shaft portion 6m. When the sliding door body 10 is slid, the door cart 6 rolls along the guide rail portion 32 m of the lower frame 32 of the door frame 3.

  As shown in FIG. 19, the lower sound insulating member 50 includes a lower hard member 501 made of a hard material such as a metal or a hard resin held in the storage chamber 51 r of the lower case 51, and the lower case 51. It is formed of a lower soft member 502 formed of a soft material such as rubber or resin held downward in the lower hard member 501 in the storage chamber 51r. Note that the lower soft member 502 has a hollow chamber 503 in order to improve the elastic deformability and tight sealability of the door frame 3 to the lower frame 32.

  As shown in FIG. 17, the lower spring member 52 is formed of a plate spring that is bent in a meandering manner so as to have a plurality of bent portions 52 m in a juxtaposed state. It extends along the extending direction of 51r, that is, along the lower side portion 12. An attachment portion 52k is attached to the bending portion 52m.

  The lower operating body 53 is provided to be movable in the arrow S1 direction (retracting direction) and the arrow S2 direction (exposing direction) at the end of the storage chamber 51r of the lower case 51. Here, the distal end portion 52 a of the lower spring member 52 and the lower operating body 53 are in contact engagement with each other, and the protruding lower operation element 56 of the lower operating body 53 is connected to the side portion of the sliding door body 10. It is provided so as to protrude outward (arrow P2 direction) from 13.

  When the sliding door 1 is slid and opened in the door opening direction (arrow P1 direction), the lower operating element 56 of the lower operating body 53 is biased by the lower spring member 52 as shown in FIG. Therefore, it protrudes in the direction (arrow P2 direction) exposed from the side part 13 of the sliding door body 10. On the other hand, when the sliding door 1 is slid in the arrow P2 direction and closed, the lower operation element 56 of the lower operation body 53 abuts on the side frame 33 of the door frame 3, and therefore the lower operation element 56 is It is moved in the retreat direction (arrow P1 direction). Then, the lower operating body 53 moves in the retracting direction (arrow S1 direction), and as a result, the bent portion 52m of the lower spring member 52 is elastically deformed so as to approach a straight shape. As a result, the lower spring member 52 moves the lower hard member 501 and the lower soft member 502 downward (gap closing direction, arrow D1 direction). As a result, the lower soft member 502 is pressed against the lower frame 32 of the door frame 3 and the lower gap 92 is closed. Thereby, the sound insulation in the lower side part 12 side of the sliding door main body 10 is ensured.

  As described above, when the sliding door 1 is opened, the bent portion 52m of the lower spring member 52 tries to restore the original shape. For this reason, as shown in FIG. 17, the lower operation element 56 of the lower operating body 53 protrudes outward (in the direction of arrow P <b> 2) from the side portion 13 of the sliding door body 10 by the urging force of the lower spring member 52. To do. Further, since the bent portion 52m of the lower spring member 52 is restored to the original shape, the lower spring member 52 moves the lower hard member 501 and the lower soft member 502 upward (in the direction of arrow D2). As a result, the lower soft member 502 is separated from the lower frame 32, so that the resistance to open the sliding door 1 is reduced.

  As described above, according to the present embodiment, the upper gap closing means 4 on the upper side 11 side of the sliding door main bodies 10 and 10E closes the upper gap 91 above the upper side 11 when the sliding door main bodies 10 and 10E are closed. Is provided. As a result, when the sliding doors 1 and 10E are closed, the upper soft member 402 constituting the upper gap closing means 4 is in pressure contact with the upper frame 31 of the door frame 3, the upper gap 91 is closed, and sound insulation on the upper side 11 side and Light shielding is ensured.

  Furthermore, according to the present embodiment, the lower gap closing means 5 for closing the lower gap 92 below the lower side 12 when the sliding door main bodies 10 and 10E are closed is provided on the lower side 12 side of the sliding door main bodies 10 and 10E. Is provided. At the same time, the lower soft member 502 constituting the lower gap closing means 5 is brought into pressure contact with the lower frame 32 of the door frame 3 to close the lower gap 92, thereby ensuring sound insulation and light shielding on the lower side 12 side. . As a result, when the sliding doors 1 and 1E are closed, sound propagation and light propagation between the first space 14x and the second space 15x are performed on both the upper side 11 side and the lower side 12 side of the sliding door body 10. It is possible to provide the sliding door 1 that is suppressed and has high sound insulation and light shielding properties.

  20 and 21 show Example 11. FIG. The present embodiment basically has the same configuration and operational effects as the tenth embodiment. A common code | symbol is attached | subjected to a common site | part. As shown in FIG. 20 and FIG. 21 (cross section along the thickness direction of the sliding door body 10), in the upper side portion 11 of the sliding door body 10, the first upper surface opening 61 is closer to the first surface 14 than the upper sound insulation member 40. In addition to being formed upward, the second upper surface opening 62 is formed upward on the second surface 15 side of the upper sound insulating member 40. Further, an upper communication path 63 that allows the first upper surface opening 61 and the second upper surface opening 62 to communicate with each other is formed inside the sliding door body 10. The first communication path 63 allows the first space 14x and the second space 15x to communicate with each other. As shown in FIG. 20, the first upper surface opening 61, the second upper surface opening 62, and the upper communication passage 63 are substantially concave in cross section.

  When the sliding doors 1 and 1E are closed, the first space 14x and the second space 15x are partitioned. Here, since the first upper surface opening 61 and the second upper surface opening 62 are formed in the upper side portion 11 of the sliding door bodies 10 and 10E, in a normal state, the user can use the first upper surface opening 61 and the second upper surface opening. The presence of 62 cannot be visually recognized. Therefore, even when the sliding door 1 is closed, the air permeability (in the direction of the arrow X1 in FIG. 20) allows the first space 14x and the second space 15x to communicate without allowing the user to recognize the presence of the vent hole. Air permeability) is ensured. Furthermore, light-shielding property is ensured while ensuring air permeability.

  Furthermore, according to the present embodiment, as shown in FIG. 21, a lateral surface opening 71 formed on the lower side of the first surface 14 of the sliding door body 10, 10E and a lower side portion 12 of the sliding door body 10, 10E are formed. A downwardly-facing lower surface opening 72 and a lower communication path 73 that connects the first space 14x and the second space 15x by communicating the surface opening 71 and the lower surface opening 72 are formed. As a result, the air permeability that allows the first space 14x and the second space 15x to communicate with each other is further ensured. Furthermore, since the lower surface opening 72 faces downward, the light of the first space 14x or the second space 15x is not transmitted, and the light shielding property is ensured.

  According to the present embodiment, as shown in FIG. 20, the upper case 41 as the base of the upper gap closing means 4 holds the upper sound insulating member 40 and forms a door nose. That is, the upper case 41 functions as a door neck, and the upper part of the upper case 41 is fitted into the door neck fitting groove 38 of the upper frame 31 of the door frame 3. Thus, by effectively utilizing the upper case 41 as the base of the upper gap closing means 4 as the door neck, the sliding door 1 is prevented from falling in the thickness direction.

  FIG. 22 shows a twelfth embodiment. The present embodiment basically has the same configuration and operational effects as the first embodiment. A common code | symbol is attached | subjected to a common site | part. As shown in FIG. 22, an internal communication path 64 is provided inside the sliding door body 10. The internal communication path 64 allows the lower communication path 73 and the upper communication path 63 to communicate with each other inside the sliding door body 10. In this case, the air permeability that allows the first space 14x and the second space 15x to communicate with each other is more easily secured.

  By the way, depending on use conditions, there may be a considerable temperature difference or humidity difference between the first space 14x and the second space 15x. In this case, the sliding door body 10 may be warped due to a temperature difference or a humidity difference between the first surface 14 and the second surface 15. Even in such a case, the atmosphere of the first space 14x and the second space 15x enters the internal communication path 64. Therefore, the inside of the internal communication path 64 tends to have an intermediate temperature or humidity between the first space 14x and the second space 15x. In this case, since an abrupt temperature difference or humidity difference acting on the sliding door main bodies 10 and 10E is reduced, there is an advantage that warpage of the sliding door main bodies 10 and 10E is reduced.

  Thus, when the sliding door main bodies 10 and 10E are closed, the air permeability between the first space 14x and the second space 15x partitioned by the sliding door main bodies 10 and 10E is ensured while enhancing the sound insulation. That is, the first upper surface opening 61, the second upper surface opening 62, and the upper communication passage 63 ensure air permeability on the upper side 11 side of the sliding door main bodies 10 and 10E. Furthermore, the front opening 71, the second lower surface opening 72, and the lower communication passage 73 ensure air permeability on the lower side 12 side of the sliding door main bodies 10 and 10E.

  Moreover, since the first upper surface opening 61, the second upper surface opening 62, and the lower surface opening 72 cannot be visually recognized by the user, the user is not allowed to recognize the presence of the vent hole. Furthermore, as shown in FIG. 22, since the opening of the vent hole is not formed on the second surface 15, the degree of freedom in selecting a design on the second surface 15 can be increased.

  Also in this embodiment, the upper case 41 as a base of the upper gap closing means 4 functions as a door neck, and the upper portion of the upper case 41 is formed in the door neck fitting groove 38 of the upper frame 31 of the door frame 3. It is inserted. Thus, by effectively utilizing the upper case 41 as the base of the upper gap closing means 4 as the door neck, the sliding door 1 is prevented from falling in the thickness direction.

As a result, the propagation of sound between the first space 14x and the second space 15x is suppressed, and the sliding door 1 with high sound insulation and light shielding can be provided.

  FIG. 23 shows a cross section along the thickness direction of the sliding door body 10. As shown in FIG. 23, on the upper side 11 side of the sliding door body 10, the second surface opening 17 u formed on the second surface 15 of the sliding door body 10, 10 </ b> E, and the first side than the upper sound insulating member 40 in the upper side 11 A first upper surface opening 61 formed on the front surface 14 side, and an L-shaped upper communication passage 63 in a cross section for communicating the second surface opening 17u and the first upper surface opening 61 are formed.

  According to the present embodiment, as shown in FIG. 23, the center line MU of the upper gap closing means 4 is eccentric by ΔM3 on the second surface 15 side from the center line MC in the thickness direction of the sliding door bodies 10 and 10E. Yes. For this reason, in the upper side part 11 of the sliding door main bodies 10 and 10E, the 1st upper surface opening 61 can be brought close to the 1st surface 14 side, and can be formed.

  Also in this embodiment, as shown in FIG. 23, the upper case 41 as the base of the upper gap closing means 4 functions as a door neck, and the upper part of the upper case 41 is the upper frame 31 of the door frame 3. It is fitted in the nose fitting groove 38. Also in the present embodiment, an internal communication path 64 is provided inside the sliding door body 10. The internal communication path 64 communicates with a lower communication path (not shown) and an upper communication path 63.
