Description

  The present invention relates to a substantially flat barrier-free sash window whose upper surface of the lower frame is at the same height level, and in particular, a sliding type equipped with a shoji and a shoji, and a single pull provided with one shoji. It can be used for sash windows.

As a sliding-type sash window, a sash window is known in which a lower frame is configured by two or more members such as a metal member and a resin member (see, for example, Patent Document 1).
Here, the window frame of the sash window is usually joined to the inner peripheral surface facing the shoji side (the inner peripheral side of the window frame) in the vertical frame with the end surfaces of the upper and lower frames in contact with screws or the like. Composed. Further, a guide piece used for pulling the shoji, a projecting piece to which an airtight or watertight sealing material is attached, and the like are provided on the inner peripheral surface of the vertical frame. Moreover, in the heat insulation sash which improved the heat insulation performance, there exist some which attached the heat insulation cover material comprised with heat insulating materials made from synthetic resin etc. to the internal peripheral surface of a vertical frame.
For this reason, at both the upper and lower ends of the vertical frame, the guide piece and the projecting piece are cut out to make the inner peripheral surface a flat plane, and the upper frame and the lower frame are brought into contact with this plane portion and joined with screws or the like. . Further, when providing a heat insulating cover material, the length of the heat insulating cover material is made shorter than the length of the vertical frame (vertical size), and the cover material is arranged on the plane portion to which the lower frame is joined. It was configured not to be.

  Therefore, as shown in FIG. 2 of Patent Document 1, the lower frame metal member and the resin member constituting the lower frame are heat insulation attached to the lower frame guide piece, the lower side of the projecting piece, and the inner surface of the vertical frame. It was placed under the cover material. For this reason, in the said patent document 1, the end part upper surface of the resin member attached to the metal member for lower frames is latched with the heat insulation cover material attached to the vertical frame, and the end part of the resin member is prevented from floating. Was.

Japanese Patent Laid-Open No. 10-325280 (FIG. 2)

By the way, in patent document 1, since the upper end height level of an outer rail and an inner rail is substantially the same, when removing the resin member arrange | positioned between each rail, you have to remove upwards.
However, in Patent Document 1, since the heat insulating cover material of the vertical frame is engaged with the upper end of the resin member, when removing the resin member, the heat insulating cover material attached to the vertical frame is first used. There is a problem that the removal work becomes complicated because it has to be removed.
Furthermore, when the resin member is disposed below the guide piece or the projecting piece that cannot be removed from the vertical frame, the resin member cannot be removed or the removal work becomes very difficult. There was a problem.

  In order to eliminate the gap between the rails, such a problem may occur when an upper surface constituent member having an upper surface at the same height level as the upper end of each rail is detachably attached to the lower frame body. When the rail member, which is the upper surface constituent member for guiding the shoji, is detachably attached to the lower frame body, such as when a barrier-free sash window having a substantially flat upper surface is formed, It was a particularly prominent problem.

  An object of the present invention is to provide a sash window that includes a lower frame main body and an upper surface component member and has a lower frame whose upper surface is substantially flat, and in which the upper surface component member can be easily removed. is there.

  The present invention is a sash window comprising a window frame composed of an upper frame, a lower frame, and left and right vertical frames, and a shoji incorporated in the window frame, wherein the vertical frame has an inner periphery of the window frame. A lower frame main body, and a lower frame main body that is detachably attached to the lower frame main body. And an upper surface constituting member constituting the upper surface of the lower frame, and the upper surface of the lower frame is formed in a substantially flat shape, and the end portion of the lower frame body is in contact with the inner peripheral surface of the vertical frame It is connected to a vertical frame, and a corner part located below the projecting portion is disposed between an end of the upper surface constituting member and the vertical frame.

According to the present invention, the corner part is disposed between the upper surface constituent member and the vertical frame, and the upper surface constituent member is configured not to be disposed below the projecting portion of the vertical frame. When the component member is removed upward with respect to the lower frame main body, it can be removed without interfering with the protruding portion of the vertical frame. For this reason, an upper surface component can be easily removed also in a lower frame with a flat upper surface. Therefore, when cleaning the surface of the lower frame main body, it is possible to easily work by removing the upper surface constituent member.
Note that the corner component is located below the projecting portion means that the upper surface constituent member is formed so as not to be located below the projecting portion, and the upper surface constituent member not located below the projecting portion. This means that corner parts are arranged between the vertical frames. Accordingly, a part of the corner part may not be disposed below the projecting part and may be located above the lower end edge of the projecting part. In short, the corner part is at least under the projecting part. What is necessary is just to have the part located in the side. That is, it is only necessary that the corner part is disposed between the end portion of the upper surface constituent member and the vertical frame, and the upper surface constituent member is not positioned below the projecting portion.
In addition, for example, when the outer rail and the inner rail are formed on the lower frame body side, the upper surface constituent member is disposed between the rails so that the wheelchair wheel can move smoothly by closing the gap between the rails. Therefore, when the rail is not formed on the lower frame main body side, it is provided to configure the outer rail and the inner rail.

Here, when either the lower frame or the shoji is attached to the other when the shoji is in the closed position, a seal material is attached, and the shoji is in the closed position. When the sliding member is located at the closed position, each sealing member is abutted against a corner part when the sliding member is located at the closed position. The tight lines are preferably continuous.
According to such a configuration, even if the tight line (airtight line) between the vertical frame and the shoji and the tight line between the lower frame and the shoji are shifted in the expected direction of the lower frame, the corner part is interposed. Thus, the tight lines can be reliably connected, and airtightness performance and watertightness performance can be improved.

Here, it is preferable that the sealing material provided between the lower frame and the shoji is attached to the upper surface constituent member.
If the sealing material is attached to the upper surface constituent member that can be attached to and detached from the lower frame body, the sealing material can be easily removed by removing the upper surface constituent member from the lower frame body even if the sealing material is damaged or deteriorated. Can be exchanged.

The corner part is preferably formed with a drain hole penetrating from the interior surface to the exterior surface of the corner part, and the drain hole is preferably provided with a drain valve.
If drainage holes are formed in the corner parts, there is no need to form drainage holes in the lower frame body and upper surface component, so the lower frame body and upper surface component manufactured by extrusion molding can be easily produced and productivity is improved. Can be improved.
In addition, since the drainage hole is provided with a drain valve, the drain valve opens so that rainwater etc. drains only when the predetermined condition is satisfied, such as when a predetermined amount of rainwater accumulates inside the drain valve. Can be configured. For this reason, it is possible to prevent the drainage hole from always opening, to prevent outside air from flowing into the indoor side of the shoji through the drainage hole, to prevent deterioration of the airtight performance, and rainwater or the like enters the indoor side from the drainage hole. Can also be prevented.
Furthermore, since the outside air does not flow into the indoor side of the shoji, the heat insulating performance of the sash window can be improved. For this reason, also when a heat insulating material is interposed in a lower frame and it is set as a heat insulating frame, the fall of heat insulation performance can be prevented.

The vertical frame includes a metal vertical frame main body and a cover material that covers an indoor exposed surface that is exposed to the indoor side when the shoji is closed in the vertical frame main body. Is provided with the inner peripheral surface and a projecting piece projecting from the inner peripheral surface, and the projecting portion of the vertical frame is composed of both the projecting piece of the vertical frame body and the cover material. Good.
In order to prevent the occurrence of condensation on the indoor exposed surface of the vertical frame, a cover material with excellent heat insulation, such as a synthetic resin cover material, may be attached, but such a cover material is attached to the inner peripheral surface of the vertical frame. When attached, the protruding portion protruding from the inner peripheral surface of the vertical frame becomes larger. Therefore, in a sash window in which a cover material is attached to a vertical frame, the projecting portion becomes larger by providing the cover material, so that the member whose end portion is located below the projecting portion can be removed as in the prior art. Although it becomes more difficult, according to the present invention, since the corner part is arranged and the upper surface constituent member is not arranged below the protruding portion of the cover material, the upper surface constituent member can be easily removed.

Here, it is preferable that the corner part is fixed to the lower frame main body, and the upper surface constituent member is fixed to the corner part with screws.
The upper surface component may be directly attached to the lower frame body, for example, but if the corner component is fixed with screws, for example, the upper surface member is made of synthetic resin and the lower frame body is made of metal such as aluminum. When the amount of thermal elongation is different, it is possible to reliably and easily prevent the edge on the corner part side of the upper surface constituent member from separating from the corner part and forming a gap.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. 1 and 2 show a longitudinal section and a transverse section of the sash window 1, but in order to make the drawings easy to see, the main structural members are not hatched in the section.

[Bottom frame structure]
Next, the lower frame 12 will be described in detail with reference to FIGS.
Between each rail 17 and 18 of the lower frame 12, the support piece part 41 integrally formed along the longitudinal direction of the lower frame 12 with respect to the outdoor member 12A is provided. An upper surface constituent member 70 is detachably attached to the upper surface of the support piece portion 41. Therefore, the lower frame main body 12D is configured by the outdoor member 12A, the indoor member 12B, and the connecting member 12C, and the lower frame main body 12D and the upper surface constituent member 70 that is detachably attached to the lower frame main body 12D. A frame 12 is configured.
And the upper surface component 70 comprises the substantially flat upper surface of the lower frame 12 with lower frame main body 12D. That is, the upper surface (upper end) height level of each rail 17, 18 and the upper surface height level of the upper surface component 70 are substantially the same, and the lower frame 12 has a gap between the rails 17, 18 in the upper surface component 70. This is a barrier-free type lower frame that is almost closed with a flat top surface and small steps.

The support piece 41 includes a rising piece 41A protruding upward from the upper surface 44 of the outdoor member 12A, a horizontal plane portion 41B extending from the upper end of the rising piece 41A to the outdoor side and the indoor side, It is between the upper end part and lower end part of 41 A of standing pieces, and is provided with the engaging part 41C extended to the indoor side from the vicinity of an upper end part. The height level of the horizontal plane portion 41B is lower than the upper end level of each rail 17, 18, but is higher than the height level of the upper surface of the connecting member 12C.
Here, the upper surface 44 is inclined so as to become lower from the indoor side toward the outdoor side, and has a water gradient. And the height position of the pocket part with which the said connection member 12C is filled is made into the upper direction rather than the highest indoor side of the upper surface 44. FIG. For this reason, the upper surface level of the connecting member 12 </ b> C is higher than the upper surface 44.

The support piece portion 41 is integrally formed with the outdoor member 12A when the outdoor member 12A is extruded, but a substantially central portion in the longitudinal direction is cut out with a predetermined width dimension. A windshield member (not shown) disposed between the rails 17 and 18 is fitted into the notch portion. The arrangement position of the windshield member corresponds to a position immediately below the summing rods 24 and 29 of the respective shojis when the respective shojis 20A and 20B are closed.
Therefore, the space above the upper surface 44 is divided into left and right by the windshield member, and between the rails 17 and 18, the area A located on the indoor side of the closed shoji 20 A, that is, outside the windshield member. The region A up to the vertical frame 13 with which the shoji 20A abuts becomes the shoji side region A corresponding to the position where the shoji 20A is in the closed state. On the other hand, the area B located outside the inner door 20B in the closed state, that is, the area B from the windshield member to the vertical frame 14 with which the inner door 20B comes into contact corresponds to the position where the inner door 20B is closed. This is the inner limb side region B.

On the other hand, an outdoor horizontal surface portion 101 extending to the indoor side is formed at the upper end of the outdoor edge of the outdoor member 12A. The outer rail 17 includes a guide portion 17A for guiding the door roller, and a rail horizontal surface portion 17B extending below the guide portion 17A to the indoor and outdoor sides at the same level as the outdoor horizontal surface portion 101. And is configured.
Further, a first attachment 110 made of a long extruded shape formed in the longitudinal direction of the lower frame 12 is formed between the outdoor horizontal surface portion 101 and the outer rail 17 and is formed along the longitudinal direction of the lower frame 12. It is detachably attached to the member 12A. The upper surface height level of the first attachment 110 is also set to the same height level as the outdoor horizontal surface portion 101.

The indoor side horizontal surface portion 102 extending to the indoor side is also formed at the indoor edge of the indoor member 12B. The inner rail 18 includes a guide portion 18A for guiding the door wheel, and a rail horizontal surface portion 18B extending below the guide portion 18A to the indoor and outdoor sides at the same level as the indoor horizontal surface portion 102. And is configured.
Further, a second attachment 120 made of a long extruded shape member formed in the longitudinal direction of the lower frame 12 is formed between the indoor horizontal surface portion 102 and the inner rail 18 and is formed along the longitudinal direction of the lower frame 12. It is detachably attached to the member 12B. The upper surface height level of the second attachment 120 is also set to the same level as the outdoor horizontal surface portion 101 and the indoor horizontal surface portion 102.

Therefore, the upper surface of the lower frame 12 extends from the outdoor side to the outdoor horizontal surface portion 101, the first attachment 110, the rail horizontal surface portion 17B, the upper surface component 70, the rail horizontal surface portion 18B, the second attachment 120, and the indoor horizontal surface portion. The flat horizontal surface by 102 and the guide portions 17A and 18A that are only slightly protruded from the flat horizontal surface form a substantially flat horizontal surface.
An indoor floor material (not shown) is disposed on the indoor side of the lower frame 12, and the indoor horizontal surface portion 102 is placed and fixed on the floor material. In addition, on the outdoor side of the lower frame 12, an outdoor floor material (not shown) that serves as a floor material for a terrace or a balcony is arranged. The upper surface of the outdoor flooring is set at the same height level as the outdoor horizontal surface portion 101.
Therefore, when the occupant moves between the interior and the exterior through the sash window (the sliding window) 1, there is no step on the indoor / outdoor floor level, so there is no need to go up and down, and it is possible to enter and exit easily, and the outdoor horizontal plane portion 101, the first attachment 110, the rail horizontal plane portion 17B, the upper surface constituting member 70, the rail horizontal plane portion 18B, the second attachment 120, and the indoor horizontal plane portion 102 are provided, so that the gap formed on the upper surface of the lower frame 12 is eliminated. Since the expected dimension (dimension in the indoor / outdoor direction) is reduced, a wheelchair caster or the like does not fit into each gap, and even a resident using a wheelchair can easily enter and exit. That is, the sash window 1 is a barrier-free type sweep window in which the floor level difference inside and outside the room is reduced.

The upper surface constituting member 70 is composed of an upper surface constituting member 70A provided in the external obstacle side region A and an upper surface constituting member 70B provided in the inner obstacle side region B.
The upper surface constituting member 70A is made of a resin material such as hard PVC (polyvinyl chloride) or a metal material such as aluminum, and is disposed in the external obstacle side region A where the closed external obstacle 20A is disposed and exposed to the indoor side. Therefore, it is preferable to use a synthetic resin material in order to improve the heat insulation performance.
On the other hand, the upper surface constituent member 70B is disposed in the inner limb side region B where the closed state inner limb 20B is disposed and is exposed to the outdoor side, so that it has excellent weather resistance such as a metal extruded shape such as aluminum. It is preferable to use a material.

Each of the upper surface constituent members 70A and 70B is formed in substantially the same cross-sectional shape, and is a rectangular tube-shaped hollow portion 701, a hanging piece 702 projecting downward from the inner surface of the hollow portion 701, and the hollow portion 701. An engagement piece 703 that projects downward from the lower surface of the hollow portion 701 and engages with the engagement portion 41C, and an engagement portion 704 that is formed on the outdoor side of the hollow portion 701 and engages with the outdoor edge of the horizontal surface portion 41B. It is prepared for.
A mounting groove is formed along the longitudinal direction on the outdoor surface of the upper surface constituting member 70A, and a sealing material 705 that contacts the inner surface of the lower arm 22 of the outer sliding element 20A is attached to the mounting groove. On the other hand, since the outer shroud 20A in the closed position is not arranged outside the upper surface constituent member 70B, no sealing material is attached to the outdoor surface of the hollow portion 701. The structure which attaches may be sufficient.

Corner parts 200 and 300 are disposed between the upper surface constituting members 70A and 70B and the vertical frames 13 and 14, respectively.
As shown in FIGS. 5 to 9, the corner component 200 is disposed between the vertical frame 13 and the upper surface constituting member 70 </ b> A. The first locking piece 134, the second locking piece 135, and the heat insulating cover 72, which are protruding portions protruding from the inner peripheral surface 13 </ b> A of the vertical frame 13, are arranged. That is, the vertical frame 13 and the lower frame 12 are screwed by abutting the end surface of the lower frame 12 to the inner peripheral surface 13A of the vertical frame 13, and therefore, the abutting portion of the lower frame 12 in the vertical frame 13 is flat. Therefore, in the lower end portion of the vertical frame 13, the portion protruding from the inner peripheral surface 13A, for example, the guide piece 131, the first locking piece 134, the second locking piece 135, etc. are cut out, The heat insulating cover 72 is also shorter than the longitudinal dimension of the vertical frame 13 so as not to reach the notch.

For this reason, the edge part of lower frame main body 12D is arrange | positioned under the said guide piece 131, the 1st locking piece 134, the 2nd locking piece 135, and the heat insulation cover 72 (just under).
However, since the corner part 200 is disposed on the end side of the upper surface component 70A, and the corner part 200 is disposed below the projecting part projecting from the inner peripheral surface of the lower frame 12, The upper surface constituting member 70 </ b> A is configured not to be disposed below (directly below) the protruding portion of the lower frame 12. That is, the upper surface constituting member 70A is configured not to overlap the protruding portion of the lower frame 12 in a plan view, and the corner component 200 is disposed at a position overlapping the protruding portion.
The protruding portion of the vertical frame 13 arranged on the extension line of the end portion of the upper surface constituting member 70A includes the first locking piece 134, the second locking piece 135, the engaging piece portion 721, and the seal material attaching portion 722. However, the protruding amount of the first locking piece 134 and the engaging piece portion 721 is very small as compared with the sealing material attaching portion 722 portion. For this reason, in the hollow portion 701 of the upper surface component 70A, the outdoor portion 701A whose position in the prospective direction is the same as that of the first locking piece 134 and the engaging piece portion 721 is closer to the vertical frame 13 than the indoor portion 701B. Is protruding. Therefore, the sealing material 705 attached to the outdoor surface of the hollow portion 701 can be extended to the vicinity of the inner peripheral surface 13A of the vertical frame 13, and the sealing material 705 is applied over the entire length of the lower collar 22 of the outer panel 20A in the closed position. Can be touched.

  As shown in FIGS. 6 and 7, the corner component 200 includes a main body 201 formed in a substantially rectangular parallelepiped shape, a protrusion 202 protruding to the outside of the main body 201, and an edge side of the main body 201 and the protrusion 202. An end edge portion 203 provided on the upper end of the end edge portion 203, a projecting piece portion 204 protruding upward from the upper surface of the end edge portion 203, and a connecting portion 205 extending to the opposite side of the end edge portion 203 of the main body 201. Configured. The corner component 200 is composed of, for example, an injection molded product made of synthetic resin.

  The upper surface of the main body 201 is slightly higher than the upper surface of the connecting portion 205. As will be described later, the upper surface 701C of the hollow portion 701 of the upper surface constituting member 70 is placed on the connecting portion 205, and the height levels of the upper surfaces of the hollow portion 701 and the main body 201 coincide as shown in FIG. Each surface is set to be flush with each other.

The protruding portion 202 protrudes from the outdoor surface of the main body 201, the height dimension thereof is lower than that of the main body 201, and the upper surface 202 </ b> A of the protruding portion 202 is at the same height level as the horizontal surface portion 41 </ b> B of the support piece portion 41. Is set to Further, the lower surface of the projecting portion 202 is configured to contact the upper surface 44 of the lower frame 12.
As shown in FIGS. 4 and 9, the end edge portion 203 is disposed below the engagement piece portion 721 of the heat insulating cover 72 and the first locking piece 134 of the vertical frame 13. Further, the edge of the upper surface constituting member 70 </ b> A and the edge of the sealing material 705 are in contact with the inner peripheral surface 203 </ b> A of the edge 203.
On the other hand, the projecting piece portion 204 is disposed between the seal member 75 and the engaging piece portion 721 of the vertical frame 13, and when the outer cover 20A is closed, as shown in FIG. 10, the seal pushed by the outer cover 20A. The material 75 is configured to be able to press contact with the protruding piece portion 204.

For this reason, when the outer screen 20A is closed, the seal member 75 of the vertical frame 13 that contacts the door toe 23 of the outer screen 20A contacts the protruding piece 204 of the corner part 200, and the Since the edge of the sealing material 705 of the upper surface constituting member 70 </ b> A that contacts the flange 22 contacts the edge 203 of the corner part 200, the sealing materials 75 and 705 are continuous via the corner part 200.
For this reason, also in the present embodiment in which the arrangement positions of the sealing materials 75 and 705 are shifted in the expected direction (indoor / outdoor direction), a continuous tight line (airtight line) is configured by interposing the corner part 200. .

  The connecting portion 205 is made lower than the main body 201 by the thickness of the upper surface 701C of the hollow portion 701, and the upper surface constituent member 70A is mounted on the corner component 200 by placing the upper surface 701C of the hollow portion 701 thereon and screwing. It is fixed to.

In the corner part 200, as shown in FIGS. That is, the drain hole 210 is a horizontal hole portion 211 formed horizontally from the indoor surface of the main body 201 to the outdoor side, and an inclination formed obliquely downward from the horizontal hole portion 211 and opened to the outdoor surface of the protruding portion 202. It is comprised with the hole part 212. FIG.
The bottom surface of the horizontal hole portion 211 is at the same height level as the top surface of the connecting member 12C, and is formed so that rainwater or the like flowing on the connecting member 12C can be discharged to the outdoor side through the drain hole 210.
In addition, a drain valve 220 that can open and close the horizontal hole 211 is rotatably attached to the horizontal hole 211. In the drain valve 220, rainwater or the like accumulates on the indoor side of the drain valve 220 (the connecting member 12 </ b> C side), and the pressure (so-called water head pressure) applied to the indoor surface of the drain valve 220 by the rainwater is the outdoor surface of the drain valve 220. It is configured to open when it becomes larger than the external pressure applied to the.

As shown in FIG. 3, the corner component 300 is disposed below the protruding piece 133, the sealing material 76, and the guide piece 132 of the vertical frame 14. Therefore, the upper surface constituting member 70B is not extended to the lower side of the protruding portion protruding from the inner peripheral surface of the vertical frame 14 because the corner component 300 is interposed between the upper surface forming member 70B and the vertical frame 14, and there is a protruding portion. It is placed in the part that does not.
Note that the lower end of the guide piece 132 abuts against the sealing material 706 attached to the lower frame 12 and the sealing material 77 attached to the door rod 28 of the inner limb 20B when the inner limb 20B is closed. In addition, an airtight member 310 that makes an airtight line constituted by these seal materials 77 and 706 continuous is attached. That is, when the inner impeller 20B is closed, the airtight member 310 is in contact with the sealing material 77, and the bottom surface of the airtight member 310 is kept in contact with the upper surface of the sealing material 706. The tight line continues through the airtight member 310.

In the inner limb side region B, since the sealing material 706 is attached to the lower frame 12 side and is not attached to the upper surface constituent member 70B, the upper surface constituent member is similar to the outdoor portion 701A of the upper surface constituent member 70A. It is not necessary to extend the end edge of 70B to the vicinity of the vertical frame 14.
The end portion of the upper surface component 70B is configured such that the upper surface 701C of the hollow portion 701 is placed on the corner component 300 and fixed with screws.
Further, the end portions on the summing portion side of the upper surface constituent members 70A and 70B are encased in the windshield plate and absorb the change when the lower frame main body 12D is thermally expanded to absorb the windshield. The upper surface constituent members 70A and 70B are configured not to be detached from the plate.

In this embodiment, when cleaning dust or the like that has entered between the rails 17 and 18, first, screws that secure the upper surface constituent members 70 </ b> A and 70 </ b> B are removed, and the support piece portion 41 is attached. The engaged engagement piece 703 and engagement portion 704 are removed. Since each of the upper surface constituent members 70A and 70B is formed so as not to interfere with the protruding portions of the vertical frames 13 and 14, it can be removed from the lower frame 12 as it is.
In order to attach the upper surface constituent members 70A and 70B after the cleaning or the like is finished, the upper surface constituent members 70A and 70B are engaged with the support piece 41 from the upper side in reverse to the above procedure, and the corner parts 200 and 300 are attached. Just screw it in.
The corner parts 200 and 300 may be attached to the lower frame 12 by screwing or fitting and fixing.

According to this embodiment, there are the following effects.
(1) The end portions of the upper surface constituent members 70A and 70B that can be attached to and detached from the lower frame 12 are not extended to the lower side of the projecting portions of the vertical frames 13 and 14, and the corner parts 200 and 300 are attached to the portions. Since it provided, when removing each upper surface structural member 70A, 70B from the lower frame 12, it can remove | eliminate without interfering with the vertical frames 13 and 14. FIG.
For this reason, because of the barrier-free type lower frame 12 in which the rails 17 and 18 have the same height level, the upper surface constituent members 70A and 70B that cannot be removed by moving to the outdoor side are moved upward. It can be easily removed. Therefore, cleaning between the rails 17 and 18 can be easily performed, and even if the upper surface constituent members 70A and 70B are damaged, they can be easily replaced, and maintenance work can be easily performed. .

  (2) By interposing the corner parts 200 and 300, the shapes of the lower frame 12 and the upper surface constituent members 70A and 70B can be set without being influenced by the vertical frames 13 and 14. For this reason, even in the sash window 1 in which the structures of the vertical frames 13 and 14 are different, the shapes of the lower frame 12 and the upper surface constituent members 70A and 70B can be made common, so that the members can be made common and production efficiency can be improved. It can also be improved.

  (3) Since the sealing material 75, 705 is brought into contact with the corner part 200 to form an airtight line (tight line), the tight line of the vertical frame 13 and the tight light of the lower frame 12 are Even if it deviates in the expected direction, each tight line can be reliably connected, and the airtight performance and watertight performance can be improved.

  (4) Since the sealing material 705 is attached to the upper surface constituting member 70A, even if the sealing material 705 is damaged, the upper surface constituting member 70A can be removed and easily replaced.

(5) Since the drain hole 210 is formed in the corner part 200, it is not necessary to separately form a drain hole in the support piece portion 41, so that the processing of the lower frame 12 is facilitated.
Moreover, since the drain valve 220 is provided in the corner part 200, it is possible to prevent the outside air flowing in from the gap between the outer rail 17 and the lower rod 22 from flowing into the indoor space defined by the sealing material 705. For this reason, outside air, rainwater, or the like does not flow into the indoor space from the drain hole 210 of the corner component 200, and deterioration of the airtight performance and the watertight performance can be prevented.
Further, since the outside air does not flow into the indoor member 12B portion, even when the outside air temperature is lower than the room temperature, the indoor member 12B is not cooled by being touched by the outside air, so that the heat insulation performance can be prevented from being lowered, and the heat insulation sash is required. It is possible to sufficiently maintain the heat insulation performance.

  (6) Since the upper surface constituent members 70A and 70B are screwed and fixed to the corner parts 200 and 300, even if the upper surface constituent members 70A and 70B are thermally expanded or contracted with respect to the lower frame main body 12D, the end portions are corners. It is possible to prevent the parts 200 and 300 from being separated from each other, and to reliably prevent a gap from being formed between the corner parts 200 and 300.

In addition, this invention is not limited to the structure of each said embodiment.

Furthermore, the fixing method of the corner component 200 is not limited to screwing, and for example, the corner component 200 may be fitted and fixed to the lower frame main body 12D, and its mounting structure can be selected as appropriate.
Further, in the corner part 200 of the embodiment, the seal materials 75 and 705 are in contact with each other to form a part of the tight line. In this case, the tight line may be configured without the corner part 200 interposed.

The upper surface constituting members 70A and 70B are screwed and fixed to the corner parts 200 and 300, but may be screwed to the lower frame main body 12D without being screwed.
Further, the upper surface constituent members 70A and 70B may be engaged and fixed to the lower frame main body 12D or the like without being screwed.
Furthermore, in the said embodiment, although the sealing material 705 was attached to 70 A of upper surface structural members, you may attach a sealing material to the lower frame main body 12D side or the collar 22 side. Moreover, in the said embodiment, although the sealing material 75 was attached to the vertical frame 13 side and the sealing material 77 was attached to the door-end side 28 side of the inner sward 20B, the sealing material 75 was attached to the door-end side 23 side of the external shoji 20A. The sealing material 77 may be attached to the vertical frame 14 side.

Moreover, this invention is applicable not only to the case where it is applied to a sliding window but also to a sliding window.
Furthermore, the structure of the window frame 10 and the shojis 20A and 20B is not limited to the above embodiment. That is, the upper frame 11, the lower frame 12, and the vertical frames 13 and 14 are each formed by connecting a general aluminum frame material and a metal indoor / outdoor member with a synthetic resin material having superior heat insulation performance compared to metal. It is possible to appropriately use a heat-insulating shape member, a heat-insulating shape member composed of a metal outdoor member and an indoor member made of a material superior in heat-insulating performance compared to a metal such as a synthetic resin or wood.
