Description

  The present invention relates to a sliding window, and more particularly, to a sliding window having airtightness at a summing unit.

  Conventionally, a sliding window has been used (see, for example, Patent Document 1). In this sliding window, a crescent and a crescent receptacle are respectively provided on the ridge located at the summing portion of the sash window.

  In the sliding window as described above, both sash windows are pulled toward each other when locked by a so-called crescent and a crescent receiver. Thereby, the airtightness in the sliding window has been ensured.

  Since the crescent and the crescent receptacle are provided in the tub located in the summoning section, respectively, the crescent and the crescent receptacle are conspicuous, and the scenery through the window tends to be lowered. Therefore, it is considered to provide a locking device that does not have to be provided on the bag located in the summoning unit. In this case, although the sliding window is locked, there is a problem that it is difficult to ensure airtightness.

FIG. 8 is a horizontal sectional view of an essential part of the sliding window according to the fifth embodiment.

  Hereinafter, the sliding window according to the first embodiment will be described with reference to FIGS.

  As shown in FIGS. 1 and 2, the sliding window 2 includes a pair of shojis 3 and 3 and a window frame 4. The window frame 4 is fixed to the inner edge of the opening 10 formed in the wall 1 of the building. In the first embodiment, an opening 10 that is rectangular in front view is formed in the wall 1, and the upper and lower edges of the opening 10 are formed horizontally. Here, the front refers to the outer surface of the wall 1 of the building. Further, the right side and the left side in a state of facing the front from the outside of the building are set as the right side and the left side, respectively.

  The window frame 4 is a so-called sash frame having a rectangular ring shape when viewed from the front, and is formed of aluminum. The window frame 4 connects the inner piece 41 located on the inner side of the building with respect to the shoji 3, the outer piece 42 located on the outer side of the building with respect to the shoji 3, and the inner piece 41 and the outer piece 42. And a connecting piece 43.

  Although the window frame 4 is fixed by the nail 11 etc. along the inner edge of the opening 10 of the wall 1 of a building, the fixing method is not limited. As the window frame 4, various conventionally used ones can be used as appropriate, and are not particularly limited. For convenience, the portions along the upper and lower sides of the window frame 4 are referred to as an upper frame 44 and a lower frame 45, respectively, as shown in FIG. 1, and the portions along the left and right sides are referred to as vertical frames 46, as shown in FIG.

  As shown in FIGS. 1 and 2, the shoji 3 includes a main body plate portion 31 and a holding rod 32. The main body plate portion 31 is made of a rectangular glass plate when viewed from the front. The main body plate portion 31 has a vertical length slightly shorter than the vertical length of the opening 10 of the building wall 1, and has a horizontal length slightly shorter than half of the horizontal length of the opening 10 of the building wall 1.

  The holding bar 32 holds the peripheral edge portion of the main body plate portion 31. The holding rod 32 has a rectangular ring shape when viewed from the front, and is formed of aluminum. The holding bar 32 has, for example, a C-shape in a cross section orthogonal to the longitudinal direction, and holds the both sides of the plate surface of the main body plate portion 31 at the peripheral edge portion of the main body plate portion 31. For convenience, as shown in FIG. 1, the portions along the upper and lower sides of the holding rod 32 are referred to as upper rods 33 and lower rods 34, respectively, and as shown in FIG. 2, the portions along the left and right sides are referred to as vertical rods 35.

  In 1st embodiment, as shown in FIG. 1, FIG. 2, the shoji 3 is a glass shoji which has the main-body board part 31 which consists of a glass plate mentioned above, and the holding rod 32. As shown in FIG. The window frame 4 holds the pair of shojis 3 and 3 so as to be movable in the moving direction 20 (see the arrow in FIG. 2) along the plate surface of the main body plate portion 31 of the pair of shojis 3 and 3. Two identical shojis 3 are used as the pair of shojis 3 and 3. The pair of shojis 3 and 3 can be moved along the longitudinal direction of the window frame 4 (that is, in the left-right direction) at positions shifted inward and outward with respect to the wall 1 of the building. For convenience, the shoji 3 located on the outer side of the building is referred to as an outer shoji 301, and the shoji 3 located on the inner side of the building is referred to as an inner shoji 302.

  As shown in FIG. 1, the window frame 4 has a pair of guide rails 47 that guide the pair of shojis 3 and 3 so as to be movable. In the first embodiment, as the guide rail 47, an upper guide rail 471 is formed on the lower surface of the upper frame 44. The upper guide rail 471 includes a single protrusion that protrudes downward in the left-right direction. Two upper guide rails 471 are formed, one on each of the outer side and the inner side of the building. The upper guide rail 471 located on the outer side of the building is the outer upper guide rail 472 that guides the shoji 301. The upper guide rail 471 located on the inner side of the building is the inner upper guide rail 473 that guides the inner shovel 302.

  As shown in FIGS. 1 and 2, similarly, as the guide rail 47, a lower guide rail 474 is formed on the upper surface of the lower frame 45. The lower guide rail 474 includes a single protrusion that protrudes upward in the left-right direction as the longitudinal direction. A lower guide rail 474 located on the outer side of the building is an outer lower guide rail 475 for guiding the shoji 301. The lower guide rail 474 located on the inner side of the building is an inner lower guide rail 476 that guides the inner shovel 302.

  As shown in FIG. 1, the shoji 3 includes a guided portion 36 that is guided by the guide rail 47. In the first embodiment, as the guided portion 36, an upper guided portion 361 is formed at the upper end portion of the upper flange 33, which is composed of one concave groove that is recessed downward with the left-right direction as the longitudinal direction. Further, as the guided portion 36, a lower guided portion 362 is formed at the lower end portion of the lower rod 34. The lower guided portion 362 is formed of a single recessed groove that is recessed upward with the left-right direction as the longitudinal direction.

  The upper guide rail 471 of the window frame 4 is inserted into the upper guide portion 361 of the shoji 3, and the lower guide rail 474 of the window frame 4 is inserted into the lower guide portion 362 of the shoji 3. Thereby, the shoji 3 is hold | maintained at the window frame 4 in the state guided so that the movement to the left-right direction was possible. As shown in FIG. 2, the pair of shojis 3, 3 held by the window frame 4 is divided into left and right within an opening (a window frame opening 40) located inside the window frame 4, The frame opening 40 is closed. At this time, the pair of shojis 3 and 3 overlap in the inner and outer directions of the building at the central portion in the left-right direction of the window frame opening 40, and the overlapping portions constitute the summing portion 37. Specifically, one of the vertical fences 35 of each of the shojis 3 and 3 overlaps the inside and outside of the building to constitute a summing unit 37.

  The sliding window 2 has a movement restricting structure 21 that restricts the shoji 3 from moving along the moving direction 20 with respect to the window frame 4. The movement restricting structure 21 is provided on at least one of the shoji 3 and the window frame 4. A so-called crescent 22 is used as the movement restricting structure 21.

  When the crescent 22 is used as the movement restricting structure 21, the crescent 22 is usually provided in the vertical rod 351 located in the summing portion 37 of one shoji 3 and the vertical position located in the summing portion 37 of the other shoji 3. A crescent receiver 23 is provided on the flange 351. In the first embodiment, one of the crescent 22 and the crescent receiver 23 is provided on the vertical rod 352 opposite to the side (door-to-door side) located on the summing portion 37 of each shoji 3 and 3. The other of the crescent 22 and the crescent receiver 23 is provided in a vertical frame 46 corresponding to one of the crescent 22 and the crescent receiver 23 in the window frame 4. With the movement restricting structure 21, the pair of shojis 3 and 3 can be locked while the pair of shojis 3 and 3 closes the window frame opening 40.

  Further, when the crescent 22 is received by the crescent receiver 23, the vertical rod 351 located in the summing portion 37 of one shoji 3 and the vertical rod 351 located in the summing portion 37 of the other shoji 3 are attracted to each other. . Thereby, a clearance gap is not formed between one shoji 3 and the other shoji 3, or it becomes difficult to form a clearance gap. In other words, the crescent 22 and the crescent receiver 23 also function as a gap reduction structure that eliminates or reduces the gap formed between the one shoji 3 and the other shoji 3.

  If a gap is formed between the one shoji 3 and the other shoji 3 in the summoning portion 37, it is difficult to ensure airtightness. That is, in a state where the pair of shojis 3 and 3 closes the window frame opening 40, the vertical eaves 351 located in the summing portion 37 of one shoji 3 and the eaves located in the summing portion 37 of the other shoji 3. When a gap is formed with 351, air flows through the inside and outside of the building through this gap. In particular, in the first embodiment, the crescent 22 and the crescent receptacle 23 are not provided in the summing portion 37, and the crescent 22 and the crescent receptacle 23 do not function as a gap reduction structure. Therefore, with the pair of shojis 3 and 3 closing the window frame opening 40, the vertical rod 351 located at the summing portion 37 of one shoji 3 and the vertical rod located at the summing portion 37 of the other shoji 3. The flanges 351 are not attracted to each other and a gap is easily formed.

  In the first embodiment, as shown in FIG. 3, the window frame 4 has a convex portion 48 at a position corresponding to the summing portion 37 of the pair of shojis 3 and 3. The convex part 48 protrudes toward the summing part 37 and pushes the holding rod 32 of one of the shojis 3. Specifically, a convex portion 48 protruding toward the inner side of the building is formed on the inner side surface of the building of the outer piece 42 of the lower frame 45. The convex portion 48 has a rectangular shape when viewed from the front. A part of the outer piece 42 is cut and raised to form a convex portion 48 that protrudes toward the inner side of the building from a portion other than the portion that becomes the convex portion 48 of the outer piece 42.

  The outer side surface of the vertical fence 351 located at the summoning portion 37 of the shoji screen 301 is located on the outer side of the building than the outer side surface of the lower arm 34 of the shoji screen 301. ing.

  When the external shoji 301 is not in a position to close the window frame opening 40, that is, when the vertical rod 351 located in the summing portion 37 of the external shoji 301 is not located in the central portion of the window frame opening 40, the convex portion 48 is It faces the lower arm 34 of the external shoji 301 but does not come into contact.

  When the external shoji 301 is in a position to close the window frame opening 40, that is, when the vertical rod 351 located in the summing portion 37 of the external shoji 301 is located in the center of the window frame opening 40, the convex portion 48 is The vertical fence 351 located on the summing portion 37 of the external shoji 301 is opposed to the vertical fence 351, and the vertical fence 35 is pushed to the inside of the building. When the vertical rod 35 is pushed, the outer screen 301 moves to the inside of the building within the range of play between the guide rail 47 and the guided portion 36, and the vertical rod 35 closes the window frame opening 40. The caliper 351 located in the summoning portion 37 of the inner shoji 302 in contact with or close to the cavern 35. As a result, a gap is less likely to be formed between the vertical rod 351 located in the summing portion 37 of the external shoji 301 and the vertical rod 351 located in the summing portion 37 of the inner shroud 302. As a result, it becomes difficult for air to flow into and out of the building through the gap between the outer shoji 301 and the inner shoji 302, and it is easy to ensure airtightness in the building.

  The convex part 48 has elasticity. That is, if the convex part 48 which protrudes toward the inner side of a building is pushed toward the outer side of a building, the protrusion length will become short. In the state where the pair of shojis 3 and 3 closes the window frame opening 40, the projection 48 becomes a summing part of the outer shoji 301 when the pushing allowance for pushing the longitudinal hook 35 of the inner shoji 302 is long. It is possible to reliably push the vertical rod 351 located at 37 toward the inner side of the building.

  Further, the provision of the convex portion 48 is not limited to the inner side surface of the building of the outer piece 42 of the lower frame 45. That is, the convex portion 48 may be formed on the inner side surface of the building of the outer piece 42 of the upper frame 44 so as to protrude toward the inner side of the building.

  Moreover, the convex part 48 may be formed in the surface of the outer side of the building of the inner piece 41 of the lower frame 45 so that it may protrude toward the outer side of a building. Further, the convex portion 48 may be formed on the outer side surface of the building of the inner piece 41 of the upper frame 44 so as to protrude toward the outer side of the building. In these cases, when the inner impingement 302 is in a position to close the window frame opening 40, the convex portion 48 comes into contact with and faces the vertical rod 351 located at the summing portion 37 of the inner shroud 302. Press to the outside of the building.

  As described above, the convex portion 48 is formed on the inner side surface of the building of the outer piece 42 of the lower frame 45, the inner side surface of the building of the outer piece 42 of the upper frame 44, and the building of the inner piece 41 of the lower frame 45. The outer side surface and the outer side surface of the inner piece 41 of the upper frame 44 are appropriately provided on one surface or two or more surfaces in any combination.

  Further, the convex portion 48 may be provided on the guide rail 47 so as to protrude toward the inner side or the outer side of the building and to be in contact with the inner side surface of the guided portion 36.

  Furthermore, in the first embodiment, the vertical rods 351 and 351 located at the summing portion 37 in both the shojis 3 and 3 are each formed of a translucent member. The translucent gutter 351 is preferably colorless and transparent, but may be colored as long as it is transparent.

  Of the holding rods 32 and 32 in both shojis 3 and 3, the holding rods 32 and 32 other than the vertical rods 351 and 351 located in the summing portion 37 are made of a member having no translucency.

  As the member having translucency, so-called transparent ceramics, transparent resins and the like manufactured by Asahi Glass Co., Ltd., Coors Tech Co., Ltd. and the like are used, but are not particularly limited.

  The vertical rods 351 and 351 located in the summing portion 37 are each made of a translucent member, so that the entire holding rods 32 and 32 of both shojis 3 and 3 can be seen as one annular frame. Thereby, the view through the window frame opening 40 is improved, and the appearance is good.

  Next, the sliding window 2 according to the second embodiment will be described with reference to FIG. The sliding window 2 according to the second embodiment is substantially the same as the sliding window 2 according to the first embodiment. For this reason, about the description which overlaps with 1st embodiment, description is abbreviate | omitted.

  In the first embodiment, the convex portion 48 is provided on the window frame 4. On the other hand, the convex part 38 is provided in both the shojis 3 in 2nd embodiment.

  The holding rod 32 for one shoji 3 has a convex portion 38 at the summing portion 37 with the other shoji 3. The convex portion 38 protrudes toward the summing portion 37 of the other shoji 3 and contacts the holding rod 32 of the other shoji 3. The convex portion 38 has a bowl shape having a protruding piece 381 and an overlapping piece 382. The protruding piece 381 protrudes from the inner surface of the building of the vertical fence 351 located at the summoning portion 37 of the external shoji 301 to the inner side of the building. The overlapping piece 382 protrudes from the tip of the protruding piece 381 toward the door stop side. The protruding piece 381 and the overlapping piece 382 are formed over the entire vertical length of the vertical rod 351. The protruding piece 381 and the overlapping piece 382 are formed of the same material as the vertical hook 351, but may be formed of a material different from the vertical hook 351.

  When the pair of shojis 3, 3 is not in a position to close the window frame opening 40, the convex portions 38 formed on the shojis 3, 3 are in positions shifted in the left-right direction and do not face each other.

  When the pair of shojis 3 and 3 are in a position to close the window frame opening 40, the overlapping piece 382 of one shoji 3 is inserted between the overlapping piece 382 of the other shoji 3 and the vertical rod 351, The overlapping piece 382 of the other shoji 3 overlaps the inside and outside of the building. In this state, the overlapping piece 382 of one shoji 3 comes into contact with the overlapping piece 382 of the other shoji 3. As a result, a gap is less likely to be formed between the vertical rod 351 located in the summing portion 37 of the external shoji 301 and the vertical rod 351 located in the summing portion 37 of the inner shroud 302. As a result, it becomes difficult for air to flow into and out of the building through the gap between the outer shoji 301 and the inner shoji 302, and it is easy to ensure airtightness in the building.

  In addition, the convex part 38 protrudes toward the summing part 37 of the other shoji 3, and does not contact the holding hook 32 of the other shoji 3, but may be close to the holding hook 32 of the other shoji 3. In this case, the distance between the holding rods 32 and 32 is appropriately determined in the range of 1 mm to 3 mm or 1 mm to 5 mm, such as 1 mm, 2 mm, 3 mm, 4 mm, and 5 mm.

  Next, the sliding window 2 according to the third embodiment will be described with reference to FIG. The sliding window 2 according to the third embodiment is substantially the same as the sliding window 2 according to the second embodiment. For this reason, about the description which overlaps with 2nd embodiment, description is abbreviate | omitted.

  Also in the third embodiment, the convex portion 38 protrudes from the holding rod 32 of one shoji 3 toward the summing portion 37 of the other shoji 3, and contacts or holds the holding rod 32 of the other shoji 3. About the point which adjoins the collar 32, it is the same as 2nd embodiment. In the second embodiment, the convex portion 38 has a bowl shape having a protruding piece 381 and an overlapping piece 382, whereas in the third embodiment, the convex portion 38 is formed in the second embodiment. The shape is different from the convex portion 38 in FIG.

  The protrusion length 383 of the convex part 38 becomes shorter as it goes to the door stop side. The protruding end surface 384 of the convex portion 38 has a planar shape, and the normal direction thereof is inclined to the door stop side with respect to the normal direction of the main body plate portion 31. The convex portion 38 is formed over the entire vertical length of the vertical rod 351. The convex portion 38 is formed of the same material as that of the vertical rod 351, but may be formed of a material different from that of the vertical rod 351.

  When the pair of shojis 3, 3 is not in a position to close the window frame opening 40, the convex portions 38 formed on the shojis 3, 3 are in positions shifted in the left-right direction and do not face each other.

  When the pair of shojis 3 and 3 are in positions where they close the window frame opening 40, the convex portion 38 of one of the shojis 3 overlaps the convex portion 38 of the other shoji 3 in the inside and outside of the building. In this state, the protruding end surface 384 of the convex portion 38 of one shoji 3 comes into contact with the protruding end surface 384 of the convex portion 38 of the other shoji 3. As a result, a gap is less likely to be formed between the vertical rod 351 located in the summing portion 37 of the external shoji 301 and the vertical rod 351 located in the summing portion 37 of the inner shroud 302. As a result, it becomes difficult for air to flow into and out of the building through the gap between the outer shoji 301 and the inner shoji 302, and it is easy to ensure airtightness in the building.

  In addition, the convex part 38 protrudes toward the summing part 37 of the other shoji 3, and does not contact the holding hook 32 of the other shoji 3, but may be close to the holding hook 32 of the other shoji 3. In this case, the distance between the holding rods 32 and 32 is appropriately determined in the range of 1 mm to 3 mm or 1 mm to 5 mm, such as 1 mm, 2 mm, 3 mm, 4 mm, and 5 mm.

  Next, the sliding window 2 according to the fourth embodiment will be described with reference to FIGS. The sliding window 2 according to the fourth embodiment is substantially the same as the sliding window 2 according to the first embodiment. For this reason, about the description which overlaps with 1st embodiment, description is abbreviate | omitted.

  In the first embodiment, the convex portion 48 is provided on the window frame 4. In contrast, the fourth embodiment is characterized by the pair of guide rails 47 included in the window frame 4.

  In the first embodiment, the distance between the pair of guide rails 47, that is, the guide rail 47 for the external shoji 301 and the guide rail 47 for the internal shroud 302 is constant regardless of the position in the left-right direction. Further, in the first embodiment, the distance between the outer upper guide rail 472 and the inner upper guide rail 473 is constant regardless of the position in the left-right direction. Also, the distance between the outer lower guide rail 475 and the inner lower guide rail 476 is constant regardless of the position in the left-right direction.

  On the other hand, in the fourth embodiment, with respect to the distance between the guide rail 47 for the external shoji 301 and the guide rail 47 for the internal shroud 302, the distance 477 at the position corresponding to the summing portion 37 is summoned. It is provided so as to be shorter than the interval 478 at a position not corresponding to the portion 37. Further, as shown in FIG. 6, as for the distance between the outer lower guide rail 475 and the inner lower guide rail 476, the distance at the position corresponding to the summing portion 37 does not correspond to the summing portion 37. Shorter than the interval at. Although not shown, the distance between the outer upper guide rail 472 and the inner upper guide rail 473 is also shorter than the distance at the position corresponding to the summing portion 37 at the position corresponding to the summing portion 37.

  In the fourth embodiment, the outer lower guide rail 475 and the outer upper guide rail 472 are formed in a linear shape, and the inner lower guide rail 476 and the inner upper guide rail 473 are formed in a curved line shape.

  The outer lower guide rail 475 and the outer upper guide rail 472 may be formed in a curved line, and the inner lower guide rail 476 and the inner upper guide rail 473 may be formed in a straight line. Further, the outer lower guide rail 475, the outer upper guide rail 472, the inner lower guide rail 476, and the inner upper guide rail 473 may all be formed in a curved line shape.

  When the pair of shojis 3, 3 is not in a position to close the window frame opening 40, the vertical rods 351, 351 located in the summing portion 37 of each shoji 3, 3 are in positions shifted in the left-right direction and do not face each other. . Further, the vertical rods 35, 35 of the respective shoji 3, 3 have a long interval 478 between the guide rail 47 for the external shoji 301 and the guide rail 47 for the inner shoji 302, and there is no possibility of contact with each other.

  When the pair of shojis 3, 3 is in a position to close the window frame opening 40, the vertical rods 351, 351 located in the summing portion 37 of each shoji 3, 3 overlap in the left-right direction. In this state, the vertical rods 351 and 351 are located in a portion where the guide rail 47 for the external obstacle 301 and the guide rail 47 for the internal obstacle 302 are at a short interval 477. For this reason, each vertical rod 351,351 contacts each other, and it becomes difficult to form a gap between the vertical rods 351,351. As a result, it becomes difficult for air to flow into and out of the building through the gap between the outer shoji 301 and the inner shoji 302, and it is easy to ensure airtightness in the building.

  Moreover, the resin member 353 is provided in the part which each vertical rod 351,351 contacts, and it is suppressed that each vertical rod 351,351 contacts directly. Polytetrafluoroethylene (Poly Tetra Fluoro Ethylene) is preferably used as the material of the resin member 353, but is not particularly limited. Note that such a resin member 353 is not necessarily provided.

  In addition, when the pair of shojis 3 and 3 are at positions where they close the window frame opening 40, the vertical rods 351 and 351 may be close to each other without contacting each other. In this case, the distance between the vertical gutters 351 and 351 is appropriately determined in the range of 1 mm to 3 mm or 1 mm to 5 mm, such as 1 mm, 2 mm, 3 mm, 4 mm, and 5 mm.

  Next, the sliding window 2 according to the fifth embodiment will be described with reference to FIG.
