Since the drain valve 90 is installed in the drain passage, only when a predetermined quantity of rainwater gathers in the water storage space 80, the rainwater is drained by opening the drain valve 90, and since the drain port 82 is not always opened, outside air and the rainwater do not flow in the indoor side from the drain port 82, to thereby prevent reduction in airtight performance and watertight performance. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

  The present invention relates to various fittings such as sliding windows, open windows, slashing windows, doors, and the like, and more particularly, to a fitting capable of draining rainwater and the like that has entered a reed holding a panel body such as glass.

In doors such as sliding windows, the shoji (door) that holds the panel body, such as glass, is composed of an upper arm, a lower arm, and a vertical arm, and in the panel body retaining groove formed on the inner peripheral surface of each arm It is comprised by hold | maintaining the edge of the said panel body through a gasket.
At this time, there is a possibility that rain water or dew condensation water may enter the tub from the gap between the panel body and the gasket or the gap between the gasket and the tub, and accumulate in the lower tub.

There is known a joinery provided with a drainage hole (drainage hole) for draining rainwater and dew condensation water collected in such a lower roof to the outside (see, for example, Patent Document 1).
In the joinery of this patent document 1, the lower outer surface of the lower heel is formed continuously with the upper facing piece and the lower bent portion of the upper facing piece, and is formed at a position on the indoor side of the upper facing piece. It consists of an opposing piece. And the drain hole was formed in the said lower end bending part, and it was comprised so that the dew condensation water which permeated in the glass plate holding groove of the lower arm could be discharged | emitted outside.

Japanese Utility Model Publication No. 62-44052 (FIG. 1)

However, in Patent Document 1, since the drain hole communicating with the outdoor side is opened in the lower jar, outside air always flows into the space in the lower jar (such as in the panel body holding groove) from the drain hole. There is a problem that the hermetic performance of the joinery is lower than in the case where such a drain hole is not formed.
Further, in the lower arm, not only the outdoor surface but also the indoor surface facing the space in the lower arm is exposed to the outside air, so that there is a problem that the heat insulation performance is lowered. In particular, it is composed of metal outdoor members and indoor members, and a connecting member made of synthetic resin or the like that is superior in heat insulation performance compared to metal, and heat conduction from the outdoor members affected by the outside air temperature is insulative. When using a heat-insulating fence that is insulated by blocking the connection member and ensuring that the heat insulation performance is not transmitted to the indoor member, the outside air will directly contact the indoor member, resulting in a decrease in the heat insulation performance. ) Cannot maintain the heat insulation performance required.
For this reason, in Patent Document 1, the heat insulation performance is maintained by covering the indoor member with the synthetic resin covering portion. However, the entire indoor member must be covered with the covering portion, which increases the manufacturing cost. There was a problem that the productivity of the heat insulating sash was also lowered.
Furthermore, since the drain hole is opened, there is a possibility that rainwater may blow directly into the lower tub from the drain hole, and the rainwater that has blown in may enter the interior of the sash from the gap between the panel body and the gasket. There was also the possibility of end.

  An object of the present invention is to provide a fitting capable of reliably draining rainwater or the like that has entered into a side wall, and in the case of a heat-insulated joinery, can prevent a decrease in heat-insulating performance and can improve airtightness.

  The joinery of the present invention is a joinery comprising an opening frame configured by framing a frame material, and a shoji disposed in the opening frame, and the shoji holds the panel body and the panel body. A vertical rod and a horizontal rod, each having a panel body holding opening for holding an edge of the panel body via an airtight material, and having a lower end edge of the panel body At least one recumbent to be held has a drain outlet provided in an outdoor side surface part facing the outdoor side in the recumbent, and a drainage channel communicating the drain outlet and the space in the panel body holding opening, The drainage port or drainage channel is provided with a drainage valve capable of opening and closing the drainage port or drainage channel.

According to the present invention, when rainwater or condensed water (hereinafter abbreviated as rainwater or the like) enters the space in the panel body holding opening, the rainwater or the like enters the outer side surface portion of the side wall through the drainage channel. It is discharged from the formed drainage port to the outdoor side.
At this time, since the drainage port or the drainage channel is provided with a drainage valve, for example, the atmospheric pressure outside the drainage valve is caused by rainwater or the like stored inside the drainage valve (panel body holding opening). When the pressure is higher than the pressure applied to the drain valve (hereinafter referred to as the water head pressure), the drain valve is closed and the drain port or the drainage channel is closed. Conversely, when the external pressure is lower than the head pressure, the drainage The valve opens and the drainage opening and drainage channel are opened, so that rainwater and the like are drained.

By providing a drain valve in the drain outlet or drainage channel in this way, the drain valve opens and drains rainwater only when a predetermined condition is satisfied, such as when a predetermined amount of rainwater has accumulated inside the drain valve. Therefore, it is possible to prevent the drain outlet and the drainage channel from always opening. For this reason, it is possible to prevent outside air from flowing into the panel body holding opening from the drain outlet or the indoor side of the shoji, to prevent deterioration of the airtight performance, and rainwater or the like can enter the room side from the panel body holding opening. Can also be prevented.
Furthermore, since the outside air does not flow into the space in the panel body holding opening, it is possible to improve the heat insulation performance of the reed. For this reason, even when a heat insulating material is intervened in the side wall, the heat insulating performance can be prevented from being lowered, and it is not necessary to cover the heat insulating material with the heat insulating material, thereby reducing the manufacturing cost and improving the productivity. Can also be improved.

Here, the drainage channel is configured to include a water storage space provided below the panel body holding opening and communicated with the panel body holding opening and the drainage port, and the drainage valve is configured as the drainage port. Or it is preferable that it is provided in the drain outlet side of the said water storage space.
According to such a configuration, since the drain outlet and the panel body holding opening are communicated with each other via the water storage space, the water that has flowed into the panel body holding opening flows into the water storage space and accumulates. When the head pressure of the water accumulated in the space becomes larger than the external pressure applied to the drain valve, the drain valve opens to drain the water in the water storage space. In this way, by forming a water storage space, it is possible to store a large amount of inflowing water and increase the water head pressure applied to the drain valve, so even when the outside air pressure is high, such as when the wind and rain are strong, it is efficient. It can be drained.

  Further, the joinery of the present invention is a joinery comprising an opening frame configured by framing a frame material, and a shoji disposed in the opening frame, and the shoji includes a panel body and the panel body. A vertical rod and a horizontal rod, each having a panel body holding opening for holding an edge of the panel body via an airtight material, and a lower end of the panel body. At least one reed holding the edge has a drain opening provided in an outdoor side surface portion facing the outdoor side of the reed to communicate the space in the panel body holding opening and the outdoor space. A drainage valve capable of opening and closing the drainage port is attached to the mouth.

  According to the present invention as described above, rainwater or the like that has entered the space in the panel body holding opening is discharged to the outdoor side from the drain port formed in the outdoor side surface portion of the side wall. At this time, since the drain outlet is provided with a drain valve, for example, the pressure outside the drain valve is reduced by rainwater or the like stored inside the drain valve (panel body holding opening side). When the head pressure is higher than the head pressure, the drain valve is closed and the drain port is closed. Conversely, when the external pressure is lower than the head pressure, the drain valve is opened and the drain port is opened. Rainwater etc. will be drained. For this reason, it is possible to prevent the drain opening from always opening, it is possible to prevent outside air from flowing from the drain opening into the panel body holding opening or the indoor side of the shoji, the deterioration of the airtight performance can be prevented, and rainwater etc. It is also possible to prevent entry into the room from the body holding opening. Furthermore, since the outside air does not flow into the space in the panel body holding opening, it is possible to improve the heat insulation performance of the reed. For this reason, even when a heat insulating material is intervened in the side wall, the heat insulating performance can be prevented from being lowered, and it is not necessary to cover the heat insulating material with the heat insulating material, thereby reducing the manufacturing cost and improving the productivity. Can also be improved.

  Here, the horizontal gutter provided with the drainage port and the drainage valve is a lower gutter that holds the lower end edge of the panel body, and protruded below the upper surface of the lower frame on the outdoor side surface portion of the lower gutter. It is preferable that a hanging piece is formed, and a lower frame drainage port for draining water that has flowed into the lower frame to the outside of the lower frame is formed in the lower frame of the opening frame.

  According to such a configuration, the rainwater and the like discharged from the drainage port of the lower gutter and flowing down along the outdoor side surface portion of the lower gutter is drained by the hanging piece and flows down below the upper surface of the lower frame. The water that has flowed down can be discharged to the outside of the lower frame through the lower frame outlet of the lower frame. For this reason, rainwater etc. can be guide | induced in a lower frame and can be discharged | emitted efficiently. Moreover, since rainwater etc. discharged from the lower gutter is guided into the lower frame, the discharged rainwater, etc. is not easily guided into the lower frame and is simply discharged to the upper surface of the lower frame. Therefore, the airtight performance can be improved without being sprayed on the airtight material portion between the lower frame and the lower heel.

In addition, the lower frame includes an upper surface having a substantially flat shape, a groove portion in which the hanging piece is disposed is formed on the substantially flat upper surface, and a drain hole is formed in the groove portion. preferable.
According to the present invention as described above, rainwater or the like that has entered the panel body holding opening is guided into the groove formed in the lower frame, and through the drain hole in the groove and the lower frame drain. It can be efficiently discharged to the outside of the lower frame, and rainwater and the like can be prevented from flowing out to the substantially flat upper surface of the lower frame. For this reason, the substantially flat upper surface of the lower frame through which a person, a wheelchair or the like passes becomes difficult to get wet with rainwater or the like, and can be prevented from slipping with water when passing.

The horizontal gutter provided with the drain port and the drain valve includes an outdoor side surface portion, an indoor side surface portion, a first connection portion that connects the side surface portions at a position below the upper edge of each side surface portion, A second connecting portion that connects each side surface portion at a position below the first connecting portion, and is partitioned by the first connecting portion and an outdoor side surface portion and an indoor side surface portion that are above the first connecting portion. It is preferable that the panel body holding opening is formed by a recess, and the water storage space is formed by a space defined by the outdoor side surface portion, the indoor side surface portion, the first connection portion, and the second connection portion.
According to such a configuration, the water storage space can be easily configured by forming a hollow portion in the lower frame, and particularly when the lower frame is configured by a metal extruded shape such as aluminum. The space can be formed integrally and can be configured easily. Moreover, the lower frame provided with the hollow part used as water storage space can raise intensity | strength by the hollow part.

The side wall provided with the drain port and the drain valve is configured to include a metal outdoor member and an indoor member, and a synthetic resin connecting member that connects the outdoor member and the indoor member, A first connecting member that connects each member at a position below the upper edge of the outdoor member and the indoor member, and a second connecting member that connects each member at a position below the first connecting member, The panel body holding opening is formed by the first connecting member, and an outdoor member and a concave portion defined by a portion of the indoor member above the first connecting member, and the outdoor member, the indoor member, and the first connecting member. The water storage space may be formed by a space defined by the second connecting member.
According to such a configuration, the water storage space can be easily configured even in the heat insulating bowl in which the metal indoor and outdoor members are connected by the connecting member made of synthetic resin. In particular, in the lower heel where the height dimension is larger than the upper heel because a door wheel or the like is provided, the outdoor member and the indoor member made of a metal extruded shape such as aluminum are usually at least up and down 2 Since they are connected by a connecting member made of synthetic resin provided at the place, the space formed between the connecting members can be used as it is as the water storage space, and the water storage space can be easily configured.

The side wall provided with the drain port and the drain valve is configured to include a metal outdoor member and an indoor member made of a material having a lower thermal conductivity than the outdoor member, and the outdoor member is An outdoor side surface portion, an indoor side surface portion, a first connection portion connecting the side surface portions at a position below the upper edge of each side surface portion, and each side surface portion at a position lower than the first connection portion. The panel body holding opening is formed by a recess defined by the first connection portion and a portion above the first connection portion of the outdoor member and the indoor member. The water storage space may be formed by a space defined by the outdoor side surface portion, the indoor side surface portion, the first connection portion, and the second connection portion of the outdoor member. Here, as an indoor member, what is comprised with the material excellent in heat insulation, such as a synthetic resin, wood, resin containing wood flour, can be utilized.
According to such a configuration, the water storage space can be easily configured even in a heat insulating trough made of a metal outdoor member and an indoor member made of synthetic resin or the like. In particular, since the water storage space is formed in the outdoor member made of a metal extruded shape such as aluminum, the strength of the outdoor member can be increased by the water storage space (hollow part). Moreover, since the rainwater etc. in a water storage space do not contact an indoor member, a wooden indoor member can also be used and the choice of the material which can be utilized as an indoor member can be increased.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In addition, in FIG. 1, although the longitudinal cross-section of the sash window 1 which is a fitting is shown, in order to make drawing easy to see, the hatching of the cross-sectional part is abbreviate | omitted about the main structural members.

[Overall structure]
In FIG. 1, a sash window 1 constitutes a sliding window, and more specifically, is a terrace door provided in a part of a detached house or apartment that goes in and out of a balcony or the like. The sash window 1 includes a window frame 10 serving as an opening frame attached to an opening of a building, an outdoor outside door 20 </ b> A and an indoor side door 20 </ b> B slidably built in the window frame 10. The screen door is built in the outdoor side of the external shoji 20A.

The window frame 10 is constituted by a four-round frame including an upper frame 11, a lower frame 12, and left and right vertical frames (not shown). Each of the frames 11 and 12 includes outdoor members 11A and 12A made of extruded aluminum, indoor members 11B and 12B made of extruded aluminum, and connecting members 11C and 12C made of synthetic resin for connecting them. It is made up of heat insulating shape. In addition, the vertical frame which is not shown in figure is comprised with the heat insulation shape material which connected the outdoor member and the indoor member made from the same aluminum extrusion shape material with the connection member made from a synthetic resin.
Here, the connecting members 11C and 12C are formed by injecting and hardening a synthetic resin such as a urethane resin into the facing pocket portions between the outdoor members 11A and 12A and the indoor members 11B and 12B. However, the connecting member may be formed by a pre-molded hard synthetic resin plate-like member, and such a plate-like member is attached between the indoor and outdoor members by caulking or the like. These connecting members 11C and 12C function as heat insulating materials that block heat conduction between the outdoor members 11A and 12A and the indoor members 11B and 12B.

The outdoor member 11A and the indoor member 11B of the upper frame 11 are provided with an outer rail 15 and an inner rail 16 that hang downward. In each of the rails 15 and 16, the upper side of the external obstacle 20A and the internal obstacle 20B is guided.
The outdoor member 12A and the indoor member 12B of the lower frame 12 are provided with an outer rail 17 and an inner rail 18 that protrude upward.

[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 is provided. A rising member 70 is attached to the upper surface of the support piece portion 41. The support piece 41 and the rising member 70 constitute a protrusion that is provided between the rails 17 and 18 and prevents a wheelchair caster or the like from being fitted between the rails 17 and 18.
On the other hand, at the indoor side end of the lower frame 12, that is, the indoor side end of the indoor member 12B, an angle portion 50 attached to the indoor floor board 5 is provided.
The height levels of the upper surfaces of the rails 17 and 18, the rising member 70, and the angle portion 50 of the lower frame 12 are substantially the same, and the lower frame 12 has almost no step on the upper surface, that is, is substantially flat. It is a barrier-free type lower frame having an upper surface. The rising member 70 is suitably made of a resin such as hard PVC (polyvinyl chloride) or a metal such as aluminum. In addition, when arrange | positioning a wind-shield member in the summoning part of the lower frame 12, it has this wind-shield member, and the outer-community side area | region where the closed-out external obstacle is arrange | positioned, and the inner-community side area | region where an internal impeller is arrange | positioned It is only necessary to arrange the rising members 70 respectively, and the materials of the rising members 70 arranged in each region may be the same or different.

A groove 51 is defined between the rising member 70 and the indoor member 12B. The groove 51 is defined by the rising member 70, the inner rail 18 of the indoor member 12B, and the connecting member 12C.
Further, a groove 52 provided adjacent to the outer rail 17 is formed on the outdoor side of the outer rail 17 of the outdoor member 12A.
One or a plurality of drain holes 53 and 54 are formed in the rising member 70 and the support piece 41 facing the groove 51, respectively, and rainwater or the like flowing into the groove 51 is transferred to the upper surface 44 of the lower frame 12. In FIG. 3, the outer rail 17, the support piece 41, the upper surface 44, the windshield member, and the water reservoir space 22 defined by the vertical frame can be discharged.

Furthermore, one or more discharge ports 23 are formed at the base end portion of the outer rail 17 facing the water storage space 22, and rainwater or the like flowing into the water storage space 22 can be drained from the discharge port 23 to the outdoor side. It is configured. In addition, the discharge port cover which has the drain valve which is not shown in figure is attached to the discharge port 23 provided in the external shoji side area. That is, since the water reservoir space 22 in the external obstacle side region is formed on the indoor side of the external obstacle 20A, it becomes an indoor side space that is blocked from outside air by the external obstacle. For this reason, the pressure (internal pressure) of the water reservoir space 22 is different from the outdoor wind pressure (external pressure).
Therefore, when the wind pressure blows to the sash window 1 side and the wind pressure increases (when the wind pressure becomes positive), the drain valve is in a state where the head pressure of rain water or the like accumulated in the water reservoir space 22 is smaller than the external pressure. Is closed, thus preventing wind from blowing into the water reservoir space 22.
On the other hand, when the head pressure of rain water or the like accumulated in the water reservoir space 22 becomes larger than the external pressure, such as when the wind pressure becomes negative pressure, the drain valve opens due to the pressure difference, and the rain water in the water reservoir space 22 is outside the outdoor space. To be drained.
On the other hand, since the water reservoir space 22 provided in the area for the inner shingle is outside the inner shrimp 20B and has the same pressure as the outside air, it is not necessary to provide the outlet 23 with the outlet cover.

  Further, a drain hole 55 is also formed on the bottom surface of the groove 52 so that rainwater or the like flowing into the groove 52 can be discharged into the hollow portion 56 formed in the outdoor member 12A. A drain hole 57 is formed in the bottom surface of the hollow portion 56 so that rainwater or the like flowing into the hollow portion 56 can be discharged to the outdoor side through the drain hole 57.

[Configuration of shoji]
The external shoji 20A arranged in the window frame 10 is composed of an upper arm 61, a lower arm 63, a vertical arm (not shown), and an outside summit arm (not shown). It is constructed in a frame shape. In addition, the inner shoji 20B is configured by assembling an upper arm (bubo) 62, an armpit (lateral) 64, a vertical arm (not shown), and an inner summon (not shown) in a square frame shape.

In addition, the hatching of the multilayer glass 65 and the gasket 66 is omitted in order to make the drawing easy to see, including drawings of other embodiments.

  Each of the flanges 61 to 64 is made of aluminum-shaped outdoor members 61A to 64A and indoor members 61B to 64B, and connecting members 61C, 62C, 631C, 632C, 633C, 641C, 642C, which are made of heat insulating materials. It is comprised with the heat insulation shape material containing 643C. In this embodiment, the upper rods 61 and 62 and the vertical rod connecting members 61C and 62C are configured by injecting resin. Also, the same resin is injected into the first connecting members 631C and 641C provided on the upper side of the lower rods 63 and 64 and the second connecting members 632C and 642C provided on the intermediate portion side in the height direction. It is configured. On the other hand, the third connecting members 633C and 643C provided on the lower side of the lower ribs 63 and 64 are configured by caulking a hard synthetic resin plate material.

[Composition of Shimojo]
Next, the structure of the lower collars 63 and 64, which is a characteristic part of the present invention, will be described in detail with reference to FIGS.
A glass holding piece 71 for holding the outdoor side of the multilayer glass 65 is formed on the outdoor members 63A and 64A of the lower rods 63 and 64, and the indoor side of the multilayer glass 65 is held on the indoor members 63B and 64B. Glass holding pieces 72 are formed respectively. Each of the indoor members 63B and 64B is formed with a hollow portion 73 having a substantially rectangular cross section.
And the panel body holding | maintenance opening part 75 is comprised by the said glass holding pieces 71 and 72, the upper surface 74 of the hollow part 73, and the groove part (recessed part) divided by the connection members 631C and 641C. The panel body holding opening 75 is opened upward, and a plurality of setting blocks 76 are disposed on the bottom surface thereof. The gasket 66 is attached to the panel body holding opening 75. The gasket 66 is a synthetic resin member having a substantially U-shaped cross section, and is engaged with the opening of the panel body holding opening 75, that is, the upper edge of each glass holding piece 71, 72.
An end portion of the multilayer glass 65 is disposed in the gasket 66. Accordingly, the multilayer glass 65 is held in the panel body holding opening 75 via the gasket 66 that is an airtight material. The load of the multi-layer glass 65 is supported by the lower collars 63 and 64 via the gasket 66 and the setting block 76.

Moreover, it is surrounded by the outdoor surface 73A in the hollow portion 73 of the indoor members 63B and 64B, the outdoor members 63A and 64A facing the outdoor surface 73A, the first connecting members 631C and 641C, and the second connecting members 632C and 642C. A water storage space 80 is formed by the created space.
The first connecting members 631C and 641C are formed with one or a plurality of communication holes 81 that allow the panel body holding opening 75 and the water storage space 80 to communicate with each other.
The outdoor members 63A and 64A are formed with one or a plurality of drain ports 82 for communicating the water storage space 80 and the external space (outside space) of the lower rods 63 and 64.
Therefore, the drain port 82 constitutes a drain port that communicates the space in the panel body holding opening 75 with the outdoor space. Further, the water storage space 80 and the communication hole 81 constitute a drainage channel from the drainage port 82 to the panel body holding opening 75.
As shown in FIG. 4, a drain valve 90 that can open and close the drain channel is attached to the drain port 82. In the present embodiment, the drain port 82 is formed on the outermost surface of the lower rods 63 and 64.

  The drain valve 90 includes a main body 91 and a valve body 92. The main body 91 has engaging protrusions 93 formed on the upper surface and the left and right side surfaces. When the main body 91 is inserted into the drain port 82 from the outside, the main body 91 is elastically deformed and the engaging projection 93 is pushed into the drain port 82, and the outdoor member is interposed between the engaging projection 93 and the surface cover portion 94. 63A is clamped. Accordingly, the drain valve 90 can be attached to the drain port 82.

The main body 91 is formed with a through-hole 95 that communicates between the water storage space 80 and the outside of the drain port 82 when attached to the drain port 82. Note that the lower surface of the through hole 95 is opened in the main body 91, and the through hole 95 is defined by bringing the main body 91 into contact with the pocket portion upper surface 67 into which the connecting member 632C of the outdoor member 63A is injected. . In addition, it is good also as the through-hole 95 divided and formed only by the main body 91, without opening the lower surface of the through-hole 95 of the main body 91. FIG.
The valve body 92 is rotatably attached to the main body 91 and is configured to open and close the through hole 95. That is, on both the left and right side surfaces of the through-hole 95, inclined portions 96 that protrude obliquely downward from the water storage space 80 side toward the outside are provided. The upper end side of the valve body 92 is rotatably attached to the main body 91, and when the both end portions of the valve body 92 abut against the inclined portion 96, the lower end edge of the valve body 92 is the pocket portion upper surface 67. It is comprised so that it may contact | abut and close the through-hole 95. FIG. The valve body 92 is configured to always contact the inclined portion 96 by its own weight because a force that works in the vertical direction with respect to the rotation axis is exerted by its own weight.

  A force in the direction of opening the valve body 92 is applied to the valve body 92 by the head pressure of rain water or the like in the water storage space 80. On the other hand, a force to close the valve body 92 is applied to the valve body 92 by the load due to the weight of the valve body 92 and the atmospheric pressure outside the valve body 92. Accordingly, when the opening force of the valve body 92 exceeds the closing force, the valve body 92 is rotated to the outside, the through hole 95 is opened, and rainwater or the like in the water storage space 80 can be discharged.

Moreover, the lower end edge of the outdoor members 63A and 64A is a hanging piece 77 extending downward from the lower end edge of the indoor members 63B and 64B. The hanging pieces 77 are arranged in the groove portions 51 and 52, respectively, and airtight materials (seal materials) 78 that are in contact with the rails 17 and 18 and are airtight are attached to the interior surfaces of the hanging pieces 77 and 52, respectively. In this embodiment, the airtight material 78 is attached to the hanging piece 77 side. However, the airtight material 78 is attached to the outdoor surface of the rails 17 and 18 and the airtight material 78 is brought into contact with the indoor surface of the hanging piece 77. May be.
Further, as shown in FIG. 1, a door wheel 32 that rolls on the rails 18 and 19 is rotatably supported on the lower rods 63 and 64, respectively.

Next, a drainage structure for draining rainwater and the like in the outer shoji 20A and inner shoji 20B will be described.
When rainwater or the like enters the panel body holding opening 75 of the external shoji 20A or the inner shoji 20B, the rainwater or the like is stored through the communication holes 81 formed in the connecting members 631C and 641C as shown in FIG. It flows into the space 80.
The pressure applied to the valve body 92 by the water stored in the water storage space 80 is greater than the force that causes the valve body 92 to contact the inclined portion 96 and close the through hole 95 due to the external pressure or the weight of the valve body 92. In the small state, the valve body 92 is kept closed. For this reason, rainwater or the like flowing into the water storage space 80 is stored in the water storage space 80.
In addition, when the valve body 92 is closed, the drain ports 82 formed in the outdoor members 63A and 64A are closed, so that outside air, rainwater, and the like can enter the water storage space 80 and the panel body holding opening from the drain port 82 portion. Therefore, the outside air, rain water and the like do not flow into the indoor space from the drain port 82.

When the water head pressure accumulated in the water storage space 80 becomes larger than the external air pressure or the like, as shown in FIG. 3, the valve body 92 is opened and the rain water or the like in the water storage space 80 passes through the through-hole 95 (drain port). 82) to the outside of the lower baskets 63, 64.
Rainwater or the like discharged to the outside flows down into the groove portions 51 and 52 from the hanging piece 77 at the lower end of the outdoor members 63A and 64A, for example, through the outdoor side surfaces of the outdoor members 63A and 64A.
Rainwater and the like flowing into the groove 51 are drained to the outside of the lower frame 12 through the drain holes 53 and 54, the water reservoir space 22, and the discharge port 23. Further, rainwater or the like flowing into the groove 52 is drained to the outside of the lower frame 12 through the drain hole 55, the hollow part 56, and the drain hole 57. Accordingly, the drainage holes 53 and 54, the discharge port 23, the drainage hole 55, and the drainage hole 57 constitute a lower frame drainage port for draining rainwater and the like flowing into the grooves 51 and 52 to the outside of the lower frame 12. ing.

According to this embodiment, there are the following effects.
(1) Since the drain valve 90 is provided in the drain port 82 for draining rainwater or the like flowing into the panel body holding opening 75 in the lower rods 63 and 64, the drain port 82 remains open. Compared to the case, outside air, rainwater, or the like does not flow into the indoor space from the drain port 82 via the panel body holding opening 75, and deterioration of the airtight performance and the watertight performance can be prevented.
Further, since the outside air does not flow into the panel body holding opening 75, for example, even when the outside air temperature is lower than the room temperature, the indoor members 63B and 64B are not cooled by touching the outside air, thereby preventing the heat insulation performance from being lowered. The heat insulation performance required for the heat insulation sash can be sufficiently maintained.
Furthermore, since the outside air does not come into contact with the indoor members 63B and 64B, there is no need to cover the entire indoor members 63B and 64B with a synthetic resin covering portion as in Patent Document 1, and the lower lids 63 and 64 The manufacturing cost, that is, the manufacturing cost of the sash window 1 can be reduced, and the productivity of the sash window 1 can be improved.

  (2) Since the water storage space 80 is formed in the lower rods 63 and 64, rainwater and the like flowing into the panel body holding opening 75 are sufficiently stored in the water storage space 80 even when the drain port 82 is closed by the valve body 92. Can be saved. For this reason, for example, even when the outdoor air pressure is high due to strong wind blowing, by storing rain water or the like in the water storage space 80 having a certain height, rain water or the like overflows from the panel body holding opening 75. The hydraulic head pressure acting on the valve body 92 can be increased. Therefore, even in a state where the atmospheric pressure in the outdoor space is high, the valve body 92 can be reliably opened and drainage can be efficiently performed, and rainwater that cannot be drained can be prevented from overflowing and entering the indoor side from the panel body holding opening 75. .

  (3) Since the drain port 82 is provided on the outdoor side surfaces of the lower rods 63 and 64, the expected dimensions of the hollow portion 73 and the hollow water storage space 80 can be made relatively large. For this reason, since a hollow part (hollow part) can be enlarged compared with the case where a drain outlet is provided in the intermediate part of the prospective direction of the lower rods 63 and 64, for example, the intensity | strength of the lower rods 63 and 64 can be improved. it can.

  (4) Since the drain port 82 is formed on the outdoor members 63A and 64A of the lower rods 63 and 64, that is, the outdoor side surfaces of the lower rods 63 and 64, rainwater discharged from the drain port 82 can be removed from the outdoor side of the lower rods 63 and 64. It can flow down from the hanging piece 77 to the lower frame 12 along the side surface. Therefore, compared with the case where the drainage port 82 protrudes to the outdoor side from the outdoor side surface portions of the lower rods 63 and 64, the rainwater drained from the drainage port 82 can be less scattered and scattered. Rain water or the like is less likely to blow back to the lower ridges 63 and 64 due to wind or the like, and rain water or the like can be efficiently drained from the lower frame 12.

  (5) Since the hanging pieces 77 of the lower rods 63 and 64 are disposed in the groove portions 51 and 52 formed in the lower frame 12, the drained rainwater can be reliably introduced into the groove portions 51 and 52 from the hanging piece 77. For this reason, in the barrier-free type lower frame in which the upper surface of the lower frame 12 is flat, rainwater or the like does not remain on the flat upper surface, and rainwater or the like can be efficiently drained to the outdoor side of the lower frame 12 and is flat. It is possible to prevent the wheel of a wheelchair from slipping by leaving rainwater or the like on the surface.

  (6) Since the drain valve 90 is configured to close the through hole 95 by bringing the valve body 92 into contact with the inclined portion 96, the closed state can be maintained by the dead weight of the valve body 92, and the negative pressure of the wind, etc. Can be prevented from opening easily. That is, the normal drain valve is configured to close the opening when the valve is oriented in the vertical direction, but in this case, the valve may open even if a slight negative pressure acts on the valve. For this reason, even if the water does not accumulate in the water storage space 80 and is not opened by the water pressure, the water storage space 80 is opened by the negative pressure of the wind, and the outside air may flow into the interior. On the other hand, in this embodiment, since the valve body 92 is configured to close the through-hole 95 in an inclined state, the closed state can be maintained by the dead weight of the valve body 92 even if some negative pressure is applied. As long as the head pressure such as 80 rainwater does not act, the valve body 92 does not open, so that inflow of outside air from the drain valve 90 portion can be reliably prevented.

(7) Since the drain valve 90 is disposed in contact with the bottom surface of the water storage space 80, that is, the pocket member upper surface 67 of the outdoor members 63A and 64A, the bottom surface of the through hole 95 can be formed by the outdoor members 63A and 64A. The structure of the valve 90 can be simplified, and water on the bottom surface of the water storage space 80 can be drained efficiently.
Moreover, since the drain valve 90 has the engagement protrusion 93, it can be attached simply by pushing the drain valve 90 into the drain port 82, and the attaching operation can be easily performed.

  (8) Since the support piece 41 and the rising member 70 are provided between the outer rail 17 and the inner rail 18, and the upper end height levels of the rails 17, 18 and the rising member 70 are substantially the same, There is no step on the upper surface, and the barrier-free sash window 1 that can move smoothly when moving in a wheelchair or when a child, an elderly person or the like walks can be configured.

  (9) Since the rising member 70 is detachably attached to the lower frame 12, the water reservoir space 22 and the like can be easily cleaned, and even if the rising member 70 is damaged, a new one can be easily obtained. Can be exchanged for

Next, a second embodiment of the present invention will be described. In the following embodiments, like the above-described embodiments, the same components are denoted by the same reference numerals, the description thereof is omitted or simplified, and the characteristic portions of the embodiments are described in detail.
As shown in FIG. 5, the second embodiment is different from the first embodiment in that the water storage space 80 is formed by a hollow portion (hollow portion) formed in the outdoor members 63A and 64A. Since it is the same as that of 1st Embodiment, description is abbreviate | omitted.

In the present embodiment, the outdoor members 63A and 64A are extended from the outdoor side surface portion to the indoor side, and are extended downward from the upper surface portion 79A. The upper surface portion 79A is formed with a pocket portion filled with the connecting member 631C. And a hollow portion surrounded by the outdoor side surface portions of the upper surface portion 79A, the indoor side surface portion 79B, and the outdoor members 63A, 64A. Thus, a water storage space 80 is configured.
The upper surface 79 </ b> A is formed with one or a plurality of communication holes 81 communicating with the panel body holding opening 75 and the water storage space 80.
In addition, a drain port 82 is formed at the joint between the outdoor side surface portion of the outdoor members 63A and 64A and the indoor side surface portion 79B, and a drain valve 90 is attached to the drain port 82. The drain valve 90 is in contact with the upper surface of the indoor side surface 79B, and the lower surface of the through hole 95 is defined by the indoor side surface 79B.

Also in this embodiment, the same operational effects as those in the first embodiment can be obtained.
Further, when the water storage space 80 is formed, the water stored in the water storage space 80 is not partitioned by the connection members 631C and 641C and the connection members 632C and 642C, and contacts the connection members 631C, 641C, 632C and 642C. Therefore, there is no need to use a synthetic resin excellent in water resistance that does not deteriorate even when it comes into contact with water, and the number of types of resins that can be used can be increased.
Furthermore, since the water storage space 80 is formed only in the outdoor members 63A and 64A, the water accumulated in the water storage space 80 does not contact the indoor members 63B and 64B, and in this respect, the heat insulation performance is further improved. be able to.
Further, since the water storage space 80 is formed by forming hollow portions in the outdoor members 63A and 64A, the strength of the outdoor members 63A and 64A can be further improved.

Next, a third embodiment of the present invention will be described with reference to FIG. In the third embodiment, the lower frame 120 is a lower frame formed in a staircase shape, and the lower ribs 630 and 640 are made of a metal shape such as aluminum and no heat insulating material is interposed. This is different from the above embodiments.
That is, the lower rods 630 and 640 include the outdoor side surface parts 631 and 641, the indoor side surface parts 632 and 642, the first connection parts 633 and 643, the second connection parts 634 and 644, and the third connection part 635. , 645, and an extruded shape of a metal material such as aluminum.

A space 80 is defined. And in the outdoor side surface parts 631 and 641, the drain port 82 is formed in the lower end part of the water storage space 80, and the drain valve 90 is attached.
The first connecting portions 633 and 643 are formed with communication holes 81 that allow the panel body holding opening 75 and the water storage space 80 to communicate with each other.
Note that the upper surface of the step-like lower frame 120 is the surface of the angle portion 50 having the highest height position in the lower frame 120.

  Also in this embodiment, rainwater that has flowed into the panel body holding opening 75 is accumulated in the water storage space 80 through the communication hole 81, and when the valve body 92 is opened by the water head pressure, the rainwater 82 is exposed to the outside. Discharged. The discharged rainwater or the like flows down on the lower frame 120 and is discharged to the outdoor side through a drainage path provided in the lower frame 120. Since the drainage path of the lower frame 120 can be the same as that of a general sash window, description thereof is omitted.

Also in this embodiment, the same operational effects as those of the first embodiment can be achieved.
Moreover, since the water storage space 80 can be formed relatively large, more rainwater can be stored in the water storage space 80 than in the above-described embodiment.

Next, a fourth embodiment of the present invention will be described with reference to FIGS. The fourth embodiment is different from the third embodiment in that a drain valve 900 is attached to a horizontal plane.
That is, in the lower collars 630 and 640, the second connecting portions 634 and 644 formed in the intermediate portion are bifurcated from the intermediate portion in the indoor / outdoor direction (expected direction) toward the outdoor side, and the outdoor side surface portion 631, A hollow portion 636 and 646 are formed together with 641.
A first drain port 820 to which the drain valve 900 is attached is formed on the upper surface of the hollow portions 636 and 646, and the water storage space 80 and the hollow portions 636 and 646 are communicated with each other via the first drain port 820. Yes. The outdoor side surfaces 631 and 641 are formed with second drain ports 830 that communicate the hollow portions 636 and 646 with the outside of the lower rods 630 and 640.
Therefore, the second drainage port 830 constitutes a drainage port that is provided on the outdoor side surface portions 631 and 641 and communicates the space in the panel body holding opening 75 and the outdoor side space. Further, the communication hole 81, the water storage space 80, the first drainage port 820, and the hollow portions 636 and 646 constitute a drainage channel from the drainage port 830 to the panel body holding opening 75. For this reason, the drain valve 900 is a drain valve capable of opening and closing the drain channel, but is disposed with the drain valve 90 provided at the drain port 82 which is an end of the drain channel in that it is provided in the middle of the drain channel. The position will be different.

  As shown in FIGS. 8 to 11, the drain valve 900 is attached to a main body 901 formed in a rectangular tube shape, a cover portion 902 formed on the upper surface of the main body 901, and the main body 901 so as to be rotatable. The valve body 910 is provided. The main body 901 and the cover portion 902 are formed with a communication hole 903 that communicates in the vertical direction, and the communication hole 903 is configured to be opened and closed by the valve body 910. The valve body 910 includes a horizontal rotation shaft 911, and includes a balancer 912 on one side and a lid 913 on the other side with the rotation shaft 911 interposed therebetween.

  The lid portion 913 extends obliquely downward from the rotary shaft 911, and the tip thereof is configured to be able to engage with and engage with a locking piece portion 904 protruding from the inner surface of the main body 901 from below. The communication hole 903 is closed by the valve body 910 by the lid portion 913 coming into contact with the locking piece portion 904.

The balancer 912 is formed so as to be heavier than the lid 913, and is provided on the opposite side by the balancer 912 via the rotating shaft 911 in a state where water does not flow into the lid 913. The lid portion 913 is set to be moved upward and maintained in a state of being locked to the locking piece portion 904. At this time, the balancer 912 is set to be positioned in a substantially horizontal direction.
Further, when a predetermined amount of rainwater or the like is stored in the space 905 defined by the lid 913 and the main body 901, the total weight of the rainwater and the lid 913 becomes heavier than the balancer 912, and the lid 913 moves downward. The weights of the balancer 912 and the lid portion 913 are set so that the balancer 912 rotates and the balancer 912 rotates upward via the communication hole 903.

In this embodiment, rainwater or the like that has entered the panel body holding opening 75 flows into the water storage space 80 via the communication hole 81. As shown in FIG. 9, rainwater that has flowed into the water storage space 80 flows into a space 905 above the lid portion 913 that extends obliquely downward in a drain valve 900 provided on the bottom surface of the water storage space 80.
Then, when a predetermined amount of rainwater flows into the space 905 above the lid 913, the lid 913 rotates downward and the communication hole 903 opens as shown in FIG. As a result, as shown in FIG. 11, rainwater or the like in the water storage space 80 flows down to the hollow portions 636 and 646 through the space 905 and the communication hole 903 and is discharged to the outside from the drain port 830.

  When rainwater or the like is discharged from the water storage space 80, the lid 913 is rotated upward by the balancer 912, engages with the locking piece 904, and stops. As a result, the communication hole 903 is closed by the valve body 910.

In this embodiment, the same operational effects as those of the above embodiments can be obtained.
In addition, since the drain valve 900 is disposed on the bottom surface of the water storage space 80, rainwater or the like in the water storage space 80 can be drained efficiently.
Furthermore, since the drain valve 900 is not exposed to the outdoor side of the lower rods 630 and 640, the appearance of the lower rods 630 and 640 can be improved.
However, since the drainage valve 900 must be installed in the water storage space 80 from the opening portions of the left and right ends of the lower rods 630 and 640, it is difficult to install the drainage valve 900 unless it is near the left and right ends of the lower rods 630 and 640.

A drain port 821 that directly communicates may be formed, and drain valves 90 and 900 may be provided in the drain port 821. In this case, since it is not necessary to form the water storage space 80 in the lower rod, there is an advantage that the height dimension of the lower rod can be suppressed.
However, as in the above embodiments, the provision of the water storage space 80 can store more rainwater and the like, and can reliably open the valve bodies 92 and 910 even when the external atmospheric pressure is high. Is advantageous.
In addition, in 4th Embodiment, the drain valve 900 is provided in the 1st connection part 633,643 part which faces the panel body holding | maintenance opening part 75, The hollow part in lower gutter 630,640 is used as a drainage channel, and this hollow part By forming a drainage port facing the water, the water may be drained through a drainage channel not provided with a water storage space.

Furthermore, in each said embodiment, although this invention was applied to the lower collar 63,64, you may apply to a horizontal rail, for example. In short, the present invention can be applied to various reeds such as a lower reed and a horizontal rail that hold the lower end edge of the panel body.
In addition, on a horizontal surface such as a lower surface or a horizontal rail, a horizontal surface that holds a panel body using a pressing edge can be used. For example, in the lower collars 63 and 64 of the first embodiment, the glass holding piece 72 portion of the indoor members 63B and 64B may be configured with a pressing edge that can be attached to and detached from the indoor members 63B and 64B.
