For example, Patent Document 1 discloses a configuration in which a drain valve component that opens and closes due to dew condensation water flowing out from the inside of an opening frame is provided at a drain port.

Japanese Patent No. 5822645

Since the drain valve component as described above has the valve closed except when draining, it is possible to prevent rainwater or the like sprayed on the fittings from the outdoor side from entering the indoor side to some extent. However, in a situation where the water level on the outdoor side of the fitting rises due to a flood or the like and the drain port is submerged, water may be inundated from a hinge or a gap around the valve. Then, there is a concern that the infiltrated water will flow into the indoor side of the fitting and cause inundation damage in the room.

The present invention has been made in consideration of the above-mentioned problems of the prior art, and an object of the present invention is to provide a fitting capable of suppressing inundation from a drain port provided in a lower frame of an opening frame.

The fitting according to the present invention is a fitting provided with a drainage port communicating with the inside of the opening frame on the outdoor side finding surface of the lower frame of the opening frame supporting the shoji, and is a stopper that covers the drainage port from the outdoor side. The lower frame is provided with a water stop member that can move to a water position and a drain position that moves from the water stop position and releases the state of covering the drain port.

According to such a configuration, even if the water level on the outdoor side of the fitting rises beyond the drainage port due to a flood or the like, the drainage port is covered from the outdoor side with the water stop member at the water stop position. Can be done. As a result, the fitting can prevent flood damage from the drainage port to the inside of the opening frame and into the room. Moreover, since the water blocking member is normally arranged at the drainage position where the state of covering the drainage port is released, the drainage of condensed water or the like from the drainage port is not hindered.

In the fitting according to the present invention, the water blocking member may be a sheet-like member that hangs down under the drainage port by its own weight by being attached to the lower frame at a position below the drainage port on the upper end side thereof. Then, the water stop member can be set to the release position by its own weight and the water stop position by the water pressure to cover the drainage port from the outdoor side without separately providing a mechanism or the like for the opening / closing operation.

In the fitting according to the present invention, the specific gravity of the sheet-shaped member is preferably smaller than the specific gravity of water. Then, since the water stop member is easily floated by the water whose water level rises on the outdoor side, the water stop member can be smoothly moved to the water stop position.

In the fitting according to the present invention, a wall member arranged on the indoor side of the sheet-like member in a hanging state below the drainage port, and a sheet-like member provided on the outdoor side of the wall member in a hanging state. The configuration may include a guide member that is interposed between the wall member and forms a gap through which water can enter between the sheet-shaped member and the wall member. Then, it is possible to prevent the water stop member from slipping under the lower frame due to the water pressure of the water, and the water stop member can be smoothly moved to the water stop position. Further, since water smoothly circulates from the gap between the wall member and the guide member to the indoor side of the water stop member, the water stop member floats more smoothly and the water stop member is prevented from adhering to the wall member. can.

In the fitting according to the present invention, the guide member has an inclined portion that is inclined so as to gradually project from the upper side to the lower side toward the outdoor side, and the inclined portion corresponds to the sheet-like member in a hanging state. It may be arranged in contact with each other. Then, since the water stop member is arranged at the drainage position in a posture of being inclined to the outdoor side along the inclined portion of the guide member, the water stop member can be more smoothly ascended to the water stop position.

The fitting according to the present invention may be configured to include a cover member having a side wall that surrounds at least the side of the water blocking member from the outdoor side with a gap provided between the fitting and the water blocking member. .. Then, even in a situation where the water force is large and the water hits the fitting in a wavy manner, this wave can be canceled by the side wall of the cover member, and the water blocking member flutters due to waviness or the like. Can be prevented. As a result, the water blocking member can smoothly float and move to the water stopping position due to the water pressure and buoyancy caused by the water flowing into the cover member relatively gently.

The fitting according to the present invention is a fitting provided with a drainage port communicating with the inside of the opening frame on the outdoor side finding surface of the lower frame of the opening frame supporting the shoji, and the upper end side thereof is located below the drainage port. It is characterized in that a sheet-like member that hangs under its own weight is provided below the drainage port by being attached to the lower frame.

According to such a configuration, even if the water level on the outdoor side of the fitting rises beyond the drainage port due to a flood or the like, the water blocking member hanging down due to its own weight floats up due to the water pressure to open the drainage port. Cover from the outside. As a result, the fitting can prevent flood damage from the drainage port to the inside of the opening frame and into the room.

According to one aspect of the present invention, it is possible to suppress flooding from a drain port provided in the lower frame of the opening frame.

As shown in FIGS. 1 and 2, the fitting 10 includes an opening frame 12 fixed to the opening 11a of the building frame 11, and shoji screens 14 and 15 supported inside the opening frame 12. In the present embodiment, one sliding window fitting 10 in which one shoji 14 is fitted and killed in the opening frame 12 and the other shoji 15 is slidably supported by the opening frame 12 is illustrated.

The opening frame 12 is formed by forming a rectangular opening by framing the upper frame 12a, the lower frame 12b, and the left and right vertical frames 12c and 12d in four directions. Each frame 12a to 12d is an extruded profile of a metal such as aluminum or a resin such as vinyl chloride resin (PVC). Each of the frames 12a to 12d constitutes the opening frame 12 by, for example, the ends having the ends cut at 45 degrees by a predetermined length are appropriately abutted against each other and joined to each other. Each frame 12a to 12d may have a composite structure in which a metal profile and a resin profile are combined. The shoji screens 14 and 15 have a structure in which the face materials 14b and 15b are held inside the frame bodies 14a and 15a.

In the present application, the prospective direction means the indoor / outdoor direction of the fitting 10, that is, the direction from the indoor side to the outdoor side or the opposite direction (the direction indicated by the arrow Y in the figure), and the prospective surface is along the prospective direction. It refers to the extending surface. The finding direction is a direction orthogonal to the expected direction, and in the case of a vertically long vertical frame 12c or the like, it means a left-right direction (direction indicated by an arrow X in the figure) orthogonal to the longitudinal direction, and is in the left-right direction. In the case of a long upper frame 12a or the like, it means a vertical direction (direction indicated by an arrow Z in the drawing) orthogonal to the longitudinal direction thereof. The finding surface is a surface along the finding direction. The inside (inner circumference) of the frame-shaped member means, for example, an inner portion (opening) of the opening frame 12. The outside (outer circumference) of the frame-shaped member means, for example, an outer portion of the frame fixed to the building frame 11 of the fitting 10.

As shown in FIG. 2, in the lower frame 12b, the shoji arranging portion 16 for holding the shoji 14 is provided on the outdoor side of the inner prospective surface, and the rail 18 on which the door roller of the shoji 15 tumblably lands is on the inner prospective surface. It is provided on the indoor side. The inner prospective surface of the upper frame 12a is also provided with a structure similar to that of the shoji arranging portion 16 and the rail 18.

The lower frame 12b has hollow portions 20, 21, 22, 23, 24, 25 in this order from the outdoor side to the indoor side. Of these, water W1 such as dew condensation water is formed on the upper wall 21a of the hollow portion 21 corresponding to the shoji arranging portion 16 and the upper walls 23a and 25a of the hollow portions 23 and 25 corresponding to both sides of the rail 18 in the prospective direction. A flowable hole is formed. Holes through which water W1 can flow are also formed in the vertical walls that partition the hollow portions 20 to 25. Therefore, the water W1 such as dew condensation water that has flowed down from the shoji screens 14 and 15 falls into the hollow portions 20, 23, 25 through the holes of the upper walls 21a, 23a, 25a, and is the outermost hollow portion 20. Inflow to.

The lower frame 12b has a drain valve component 28 on the outdoor side finding surface 26 which is the outdoor side wall of the hollow portion 20 into which the water W1 flows. The drain valve component 28 is fitted and mounted in a rectangular hole formed in the outdoor side finding surface 26, and constitutes a drain port for discharging water W1 to the outside. As shown in FIG. 3, the drain valve component 28 has a structure in which a drainage path 28a that allows water W1 to flow in the indoor and outdoor directions and a valve 28b that opens and closes the drainage path 28a are provided in the housing 28c. The valve 28b is, for example, a rectangular plate, and is rotatably supported by the housing 28c via hinges 28d provided on the left and right sides of the upper end portion. The valve 28b normally closes the drainage path 28a by its own weight or the urging force of an elastic body, and opens by being pressed outward by the water pressure of water W1 (the valve shown by the chain double-dashed line in FIG. 3). 28b). The drain valve component 28 may have a configuration in which the drain path 28a is always open without having the valve 28b. The drain valve component 28 may be omitted, and the opening itself provided on the outdoor side finding surface 26 of the lower frame 12b may be used as the drain port.

As shown in FIG. 2, the lower frame 12b includes a first mounting piece 30 protruding inward from the indoor side end of the outer prospecting surface and a second mounting piece 31 protruding downward from the outer prospecting surface. Have. In the lower frame 12b, the first mounting piece 30 is fixed to the upper surface of the building skeleton 11 (bottom surface of the opening 11a) via the fixture 32, and the second mounting piece 31 attaches the fixture 32 to the outdoor surface of the building skeleton 11. It is fixed through. As a result, the lower frame 12b is fixed to the building skeleton 11 in a posture in which the outdoor portion including the shoji arranging portion 16 for holding the shoji 14 projects from the building skeleton 11 to the outdoor side. In the lower frame 12b, an L-shaped support member 33 and an outer wall member 34 are attached to an outer prospective surface of a portion protruding from the building frame 11. That is, the fitting 10 of the present embodiment is installed in a state in which a part of the outdoor side of the fitting 10 projects to the outdoor side of the outer wall surface (outer wall member 34) of the building.

By the way, in such a fitting 10, when the water level on the outdoor side rises due to heavy rain, flood, etc. and the drain valve component 28 is submerged, the drain valve component 28, the drain valve component 28, and the lower frame 12b Water may enter the room through the gap of the fitting part with. Therefore, the fitting 10 of the present embodiment includes a water blocking structure 40 that suppresses the backflow of water from the outdoor side to the indoor side.

FIG. 4 is an enlarged front view of a part of the lower frame 12b provided with the water blocking structure 40, and is a view of the drain valve component 28 of the lower frame 12b and its peripheral portion as viewed from the outdoor side.

As shown in FIGS. 1, 2 and 4, the fitting 10 includes a water stop structure 40 capable of surrounding the drain valve component 28, which is a drain port provided on the outdoor side finding surface 26, from the outdoor side. The water stop structure 40 includes a water stop member 42, a wall member 44, a guide member 46, and a cover member 48.

FIG. 5A is an enlarged perspective view of a main part in a state where the water blocking member 42, the wall member 44, and the guide member 46 are attached to the lower frame 12b. FIG. 5B is an enlarged perspective view of a main part in a state where the water blocking member 42 is removed from FIG. 5A. FIG. 5C is an enlarged perspective view of a main part from the state shown in FIG. 5A with the cover member 48 attached.

As shown in FIGS. 2, 4 and 5A, the water blocking member 42 is, for example, a sheet-like member having flexibility of hanging downward due to its own weight. It is preferable that the water blocking member 42 has a specific gravity smaller than that of water and has a property of floating on water. The water blocking member 42 is made of, for example, a sheet of silicone, rubber, resin, or the like.

The water stop member 42 is attached to the outdoor side edge portion 50 of the outer prospective surface whose upper end side is the lower surface of the lower frame 12b by using a pair of left and right screws 52 and 52. Specifically, the water blocking member 42 is screwed and fixed to the outdoor edge portion 50 in a state where the upper end side thereof is inserted from the outdoor side with respect to the lower surface side of the lower frame 12b. As a result, the water stop member 42 normally hangs down under its own weight below the outdoor side finding surface 26 and the drain valve component 28 of the lower frame 12b (see FIGS. 2 and 5A). In the case of the present embodiment, the mounting plate 44a of the wall member 44 is fixed to the outdoor edge portion 50 of the lower frame 12b. Therefore, the water blocking member 42 is fastened to the outdoor edge portion 50 together with the mounting plate 44a with screws 52 in a state of being sandwiched between the mounting plate 44a and the outdoor edge portion 50.

Such a water blocking member 42 has a shape capable of completely covering and adhering to the drain valve component 28 from the outdoor side when it is rolled up upward with the end of the outdoor side edge portion 50 as a fulcrum. .. That is, the water stop member 42 has a width dimension in the left-right direction (X direction) that is sufficiently larger than the drain valve component 28, and a vertical direction (Z direction) that can cover the upper part of the drain valve component 28 when it is rolled up. ) Has a height dimension.

As shown in FIGS. 2 and 5B, the wall member 44 is an angle-shaped member having a mounting plate 44a in the indoor / outdoor direction and a wall plate 44b in the vertical direction. The wall member 44 is a member obtained by bending a metal plate such as stainless steel, steel, or aluminum into a substantially L shape. The mounting plate 44a is a portion that is fastened to the outdoor edge portion 50, which is the lower surface of the lower frame 12b, with screws 52. The wall plate 44b hangs below the outdoor side finding surface 26 of the lower frame 12b along the outdoor side finding surface 26. The wall plate 44b is arranged on the indoor side of the water blocking member 42 that hangs down due to its own weight, and prevents the water blocking member 42 from entering below the lower frame 12b. The wall plate 44b may be provided at a position protruding outside the outdoor side finding surface 26.

As shown in FIGS. 2 and 5B, a pair of left and right guide members 46 are provided on the outdoor side surface of the wall plate 44b of the wall member 44. Each guide member 46 is a member obtained by bending a metal plate such as stainless steel, steel, or aluminum into a substantially U shape. Each guide member 46 is fastened to the wall plate 44b by using a screw 54 at a portion that becomes a U-shaped bottom plate. Each guide member 46 is an inclined portion 46a that is inclined so that the end faces of the portions that serve as the U-shaped side plates gradually project from the upper side to the lower side toward the outdoor side. That is, the inclined portion 46a gradually projects from the upper part to the lower part in a direction away from the outdoor side finding surface 26, and becomes a contact support surface of the hanging water blocking member 42. As a result, the guide member 46 is interposed between the indoor side surface of the water blocking member 42 in a state of hanging below the outdoor side finding surface 26 and the drain valve component 28 and the wall plate 44b of the wall member 44 to stop water. A gap G through which water can enter is formed between the member 42 and the wall plate 44b. The guide member 46 may have a configuration in which the water blocking member 42 is abutted and supported by an end face extending in the vertical direction instead of the inclined portion 46a as long as the gap G can be formed.

As shown in FIGS. 2, 5A and 5C, the cover member 48 is formed in a box shape in which two surfaces, an indoor side surface and a lower surface, are open. The cover member 48 is a component that surrounds the water stop member 42 from the outdoor side with a gap C that does not interfere with the movable range of the water stop member 42. The cover member 48 has a structure in which a three-sided plate of a metal plate formed of, for example, stainless steel, steel, aluminum, or the like in a convex shape is bent toward the indoor side. The cover member 48 has an upper surface wall 48a that surrounds the upper part of the water blocking member 42, and side walls 48b, 48c, 48d that surround the three sides of the water blocking member 42.

Mounting pieces 48e bent in a direction away from each other are provided at the indoor side ends of the left and right side walls 48c and 48d, respectively. Each mounting piece 48e is formed with a through hole through which a screw 56 can be inserted. The cover member 48 is installed with the left and right side walls 48c and 48d straddling the water blocking member 42, and each mounting piece 48e is fastened to the wall plate 44b of the wall member 44 using screws 56. In this mounted state, the cover member 48 is arranged so that the indoor end portion of the upper surface wall 48a is in contact with the outdoor side finding surface 26 above the water stop member 42 and the drain valve component 28, and the left and right side walls 48c and 48d. The indoor side end is arranged in contact with the outdoor side finding surface 26 and the wall plate 44b at a position straddling the water blocking member 42. At this time, an opening 48f is formed on the lower surface side of the cover member 48 to communicate the gap G with the outside. In the case of the present embodiment, above the outdoor side finding surface 26 of the lower frame 12b, a cover piece 58 arranged substantially flush with the outdoor side finding surface 26 is screwed and fixed by screws 59. Therefore, the indoor end portion of the upper surface wall 48a is actually arranged in contact with the cover piece 58. The cover member 48 may extend in the longitudinal direction of the lower frame 12b, for example, and may enclose the left and right drain valve parts 28 together.

Next, the water-stopping action of the water-stopping structure 40 will be described. FIG. 6A is an enlarged vertical cross-sectional view of a main part showing a normal state of the water blocking structure 40. FIG. 6B is an enlarged vertical cross-sectional view of a main part showing a state of the water blocking structure 40 when the water is stopped. FIG. 7 is an enlarged front view of a main part of the water stop structure 40 when the water is stopped, as viewed from the outdoor side.

First, as shown in FIG. 6A, in a normal state where water does not overflow to the outdoor side of the fitting 10, the water blocking member 42 hangs down under the outdoor side finding surface 26 and the drain valve component 28 of the lower frame 12b due to its own weight. The indoor side surface thereof is in contact with the inclined portion 46a of the guide member 46. In this state, a gap G is formed by the guide member 46 between the indoor side surface of the water blocking member 42 and the wall plate 44b of the wall member 44. Further, a gap C is provided between the outdoor side surface of the water blocking member 42 and the inner surface of the cover member 48. At this time, the water stop member 42 is surrounded by the upper surface wall 48a and the side surface walls 48b to 48d of the cover member 48 on the upper side and the side surface thereof. Therefore, the water blocking member 42 is protected by the cover member 48 from external factors such as ultraviolet rays, wind and rain, and contact with birds and people.

In such a normal state, the water stop member 42 is separated from the outdoor side finding surface 26 and the drain valve component 28, and is in a drain position that allows drainage from the drain valve component 28 without covering the drain valve component 28. Therefore, for example, the water W1 such as the condensed water generated in the shoji screens 14 and 15 pushes the valve 28b open from the drainage path 28a of the drain valve component 28 and is smoothly drained to the outside (see FIG. 2).

Next, as shown in FIG. 6B, when water overflows to the outdoor side of the fitting 10 due to heavy rain or flood, and the water level on the outdoor side rises, water flows from the opening 48f or the like to the gap C inside the cover member 48. W flows in. As a result, the water level inside the cover member 48 gradually rises. Therefore, the water W floats the water stop member 42 while wrapping around from the gap G to the indoor side of the water stop member 42. Then, the water blocking member 42 rises due to the buoyancy with respect to the water W while being rolled upward in the counterclockwise direction in FIG. 6B with the outdoor end of the outdoor edge 50 as a fulcrum. For example, when the water level of the water W rises to about the intermediate height of the drain valve component 28, the water stop member 42 floats along the water surface as shown by the alternate long and short dash line in FIG. 6B, and the lower half of the drain valve component 28. It is in close contact with the water and covers it.

At this time, the fitting 10 is provided with the wall member 44 on the back surface (indoor side surface) side of the water blocking member 42 which is a flexible sheet-like member. Therefore, it is prevented that the water blocking member 42 receives the water pressure of the water W and slips below the lower frame 12b. Further, in the fitting 10, a gap G is formed between the back surface side of the water blocking member 42 and the wall member 44 by the guide member 46. Therefore, the water W smoothly wraps around from the gap G to the back side of the water stop member 42, the water stop member 42 floats more smoothly, and the water stop member 42 can be prevented from adhering to the wall plate 44b. Further, since the guide member 46 has the inclined portion 46a, the water blocking member 42 can be smoothly ascended while being rolled up to the outdoor side.

When the water level rises further and becomes, for example, a water level Wh or higher that completely submerges the drain valve component 28 (see FIG. 6B), the water stop member 42 is rolled up to the uppermost position. As a result, the water stop member 42 came into close contact with the outdoor side finding surface 26 and the drain valve component 28 of the lower frame 12b by the water pressure of the water W at the water level Wh, and completely covered the drain valve component 28 from the outdoor side. It becomes a water stop position. As a result, the gap around the valve 28b of the drain valve component 28 and the gap of the fitting portion between the drain valve component 28 and the lower frame 12b are covered from the outdoor side by the water blocking member 42 (see also FIG. 7). Therefore, it is possible to prevent water W from entering the inside of the opening frame 12 from the gap (drainage path 28a) around the valve 28b of the drain valve component 28 and its surroundings, and it is possible to prevent flood damage from occurring in the room. ..

At this time, since the water blocking member 42 of the present embodiment is a sheet-like member having a specific gravity smaller than the specific gravity of water, the drain valve component 28 can be hidden while surely floating on the water surface of the rising water W. .. Moreover, the fitting 10 includes a cover member 48 that surrounds the water blocking member 42 with a gap C. Therefore, even in a situation where the water force of the water W is large and the water W is pressed against the fitting 10 in a wavy manner, the wave is canceled by the cover member 48 (particularly, the side walls 42b to 42d). The water blocking member 42 does not flutter due to waviness or the like. As a result, the water blocking member 42 smoothly floats due to the water pressure and buoyancy of the water W flowing into the cover member 48 relatively gently, and comes into close contact with the drain valve component 28 and the outdoor side finding surface 26 around the drain valve component 28. Can be done.

FIG. 8A is an enlarged vertical cross-sectional view of a main part showing a normal state of the water blocking structure 40A according to the modified example. FIG. 8B is an enlarged vertical cross-sectional view of a main part showing a state of the water blocking structure 40A shown in FIG. 8A when the water is stopped.

As shown in FIG. 8A, the water blocking structure 40A has a water stopping member 42A which is a sheet-like member having substantially the same shape and substantially the same quality as the water stopping member 42 described above. The water stop member 42A has a structure in which the above-mentioned water stop member 42 is rolled up in advance and the upper end side thereof is fastened to the outdoor side finding surface 26 (cover piece 58 in FIG. 8A) by a screw 60. That is, the lower end side of the water blocking member 42A is fixed to the outdoor side edge 50 of the lower frame 12b with screws 52, and the upper end side is fixed to the outdoor side finding surface 26 of the lower frame 12b with screws 60. Although the guide member 46 is omitted in the configuration example shown in FIG. 8A, the wall member 44 may be further omitted.

Next, the water-stopping action of such a water-stopping structure 40A will be described. First, as shown in FIG. 8A, in a normal state where water does not overflow to the outdoor side of the fitting 10, the water blocking member 42A does not come into close contact with the outdoor side finding surface 26 and the drain valve component 28 of the lower frame 12b, but by its own weight. It is in a state of being bent like a sail. In such a normal state, the water stop member 42A is located at a drainage position that allows drainage from the drain valve component 28 away from the outdoor side finding surface 26 and the drain valve component 28. Therefore, for example, water W1 such as dew condensation water generated in the shoji screens 14 and 15 can be smoothly drained from the drain valve component 28 to the outside through gaps formed so as to swell on both the left and right sides of the water stop member 42A (FIG. 2). reference).

Next, as shown in FIG. 8B, when water overflows to the outdoor side of the fitting 10 due to heavy rain or flood, and the water level on the outdoor side rises, water flows from the opening 48f or the like to the gap C inside the cover member 48. W flows in. As a result, the water level inside the cover member 48 gradually rises, so that the water pressure of the water W presses the water stop member 42A toward the indoor side. Therefore, the drain valve component 28 and its peripheral portion are gradually covered with the water blocking member 42A from below. Then, for example, when the water level becomes Wh or higher so as to completely submerge the drain valve component 28 (see FIG. 8B), the water stop member 42A has the outdoor side finding surface 26 of the lower frame 12b and the drain valve due to the water pressure of the water W. The water stop position is such that the drain valve component 28 is in close contact with the component 28 and completely covered from the outdoor side. As a result, the gap between the drain valve component 28 and the fitting portion between the drain valve component 28 and the lower frame 12b is covered from the outdoor side by the water blocking member 42A. Therefore, it is possible to prevent water W from entering the inside of the opening frame 12 from the drain valve component 28 and its surroundings, and it is possible to prevent flood damage from occurring in the room.

As described above, the fitting 10 according to the present embodiment has a configuration in which the drain valve component 28 serving as a drain port is provided on the outdoor side finding surface 26 of the lower frame 12b, and the water stop position that covers the drain valve component 28 from the outdoor side. The water stop member 42 (42A) is provided so that the state of moving from the water stop position and covering the drain port is released and the water stop member 42 (42A) can move to the drain position where drainage from the water stop position is allowed. Therefore, even if the water level on the outdoor side rises beyond the drain valve component 28 that serves as the drain port due to a flood or the like, the fitting 10 is drained by the water stop member 42 (42A) that is in the water stop position. The mouth can be covered from the outside to stop water. As a result, the fitting 10 can prevent flood damage from the drainage port to the inside of the opening frame 12 and into the room. It is desirable that the water-stopping action of the drainage port by the water-stopping member 42 (42A) can completely prevent water from entering from the drainage port, but at least the drainage is performed as compared with the case where the water-stopping member 42 (42A) is not provided. It suffices if the amount of water infiltrated from the mouth can be reduced.

It should be noted that the present invention is not limited to the above-described embodiment, and of course, it can be freely changed without departing from the gist of the present invention.

In the above embodiment, the fitting 10 which is a single sliding window is illustrated, but the fitting 10 may be another sliding window such as a sliding window, a rotating window such as a casement window, a raising / lowering window, a fitting window, a door or the like. good. Further, for example, the shoji 14 may have a fitting structure in which the face member 14b is directly held by the opening frame 12 without having the frame body 14a.

In the above embodiment, the water blocking structure 40 has an example of a configuration including a wall member 44 and a guide member 46, but a configuration in which only one of them is provided may be provided. That is, even if the wall member 44 is omitted, the function of the wall plate 44b of the wall member 44 can be ensured by the guide member 46. Similarly, even if the guide member 46 is omitted, the function of the guide member 46 can be ensured by the wall member 44. When the guide member 46 is omitted, the wall member 44 may have the same angle of the wall plate 44b as the inclined portion 46a. Further, when the guide member 46 is omitted, the same effect as the gap G can be obtained by forming a large number of holes in the wall plate 44b or by forming the wall plate 44b with a punching metal, a mesh, or the like. In other words, in this configuration, the wall member 44 substantially functions as a guide member.
