  On the other hand, in a fitted round window having a sash frame formed by mechanically joining the ends of the profile, the manufacturing cost can be kept low, but the capillary phenomenon occurs between the joint surfaces of the ends of the profile. There is a risk that rainwater or the like may enter from the outdoor side to the indoor side. When water such as rainwater enters the indoor side, there are problems such as corrosion of the building frame. In order to prevent water from entering due to capillarity, a method of filling the silicon material between the joint surfaces of the end portions of the shape material can be considered, but visually check the filling state of the silicon material between the joint surfaces. Not only is it difficult, there is a risk that the filled silicon material may be cut off.

  The present invention has been made in view of the above circumstances, and prevents water from entering the indoor side from the outdoor side by being transmitted between the joint surfaces of the end portions of the shape member constituting the sash frame by a capillary phenomenon. The object is to provide a round window that can be fitted.

  The present invention comprises an annular sash frame, a panel incorporated in the sash frame from the indoor side, and a pushing edge attached to the sash frame from the indoor side to fix the panel, wherein the sash frame is The ends of the sections bent into one circle or two semi-circles are mechanically joined to each other, and the joint faces between the ends of the sections are transmitted between the joint faces by capillary action. It is characterized in that a notch is provided for draining water entering the indoor side from the outside along the inner periphery of the sash frame.

  According to the present invention, there is provided an annular sash frame, a panel incorporated in the sash frame from the indoor side, and a pressing edge attached from the indoor side to the sash frame to fix the panel. The frame is formed by mechanically joining the ends of the shape members bent into one circle or two semicircles, and is transmitted to the joint surfaces between the end portions of the shapes by capillarity. Since there is a notch for draining water that enters the room from the outside to the inside along the inner periphery of the sash frame, the gap between the joint surfaces of the ends of the sash frame It is possible to prevent water from entering from the outdoor side to the indoor side due to the capillary phenomenon.

  The best mode for carrying out the present invention will be described below in detail with reference to the accompanying drawings. FIG. 1 is a longitudinal sectional view showing a frame-fitting type round window that is an embodiment of the present invention, FIG. 2 is an outdoor perspective view of the same type of round window, and FIG. 3 is an indoor side view of the same type of round window. 4 is a partially omitted sectional view taken along the line AA of FIG. 2, and FIG. 5 is a partially omitted perspective view of the main part. FIG. 6 is a diagram for explaining the movement of the infiltrated water, FIG. 7 is a diagram showing another example of the main part, FIG. 8 is an explanatory diagram for explaining the movement of the pressing edge when screwing, and FIG. It is a longitudinal cross-sectional view which shows a stowage type fitting round window.

  In these drawings, reference numeral 1 denotes a fitting round window. The fitting round window 1 includes an annular sash frame 4 fixed to a circular opening 3 of a housing 2 of a building from the outdoor side, and an inside of the sash frame 4. A panel 5 incorporated from the indoor side into the sash frame 4 and a pushing edge 6 attached to the sash frame 4 from the indoor side to fix the panel 5. A mounting fin 8 for fixing the sash frame 4 to the housing 2 with a fixing tool, for example, a screw 7 is provided on the outer periphery of the sash frame 4. 9 is provided. A panel fixing fin 10 for fixing the peripheral edge of the panel 5 from the indoor side to the inner periphery of the sash frame 4 and a pressing edge 6 for fixing with a fixing tool such as a screw (screw) 11. A pressing edge fixing fin 12 is provided. The pushing edge fixing fin 12 includes a rising portion 12a rising from the inner periphery of the sash frame 4, and a cylindrical extending portion 12b extending from the rising portion 12a to the indoor side. A push edge is fixed to the peripheral surface with a screw 11. In the illustrated example, the rising portion 12a and the mounting fin 8 are substantially in the same position in the indoor / outdoor direction, but the present invention is not limited to this.

  The sash frame 4 is formed by mechanically joining the ends of a shape member 13 bent into one circle or two semicircles. In the illustrated sash frame 4, as shown in FIG. 2, the ends of the upper and lower shapes 13 bent into two semicircular shapes are mechanically joined by a joint member 14 and a fixing tool such as a screw 15. Do it. The shape member 13 is made of metal, for example, aluminum, and is bent into a semicircle by a bending machine. As shown in FIGS. 2 to 5, the two shape members 13 are end-to-end (abutted or joined) to each other, and a metal-like, for example, aluminum plate-like joint member 14 is connected to the outside of the joining portion. The joint members 14 are mechanically joined to each other by being fixed to each end with screws 15.

  In this case, on the joint surface 16 between the end portions of the shape member 13, the water that is transmitted between the joint surfaces 16 by capillary action and enters the indoor side from the outdoor side is made to follow the inner periphery of the sash frame 4 in the middle. For example, a substantially U-shaped or groove-shaped notch 17 for draining is provided. As shown in FIG. 5, rainwater or the like that enters between the joint surfaces 16 from the outdoor side toward the indoor side due to capillary action is caused by gravity due to the capillary action being cut off at the position of the notch 17. As shown in the drawing, the outer peripheral surface side of the sash frame 4 at the notch 17 is covered with the joint member 14, whereas the inner peripheral surface side of the sash frame 4 is opened, It flows out to the inner peripheral surface side and is drained downward along the inner peripheral surface of the sash frame 4.

  As shown in FIG. 4, a tape-shaped sealing material 18 made of, for example, butyl rubber is attached to the outer peripheral surface of the shape member 13 so as to cover the joining surface 16 or the joining portion between the ends of the shape member 13 from the outside. A silicon member 19 is provided on the inner peripheral surface of the shape member 13 so as to cover the joint surface 16 or the joint portion from the inside except the notch portion 17. The tape-shaped sealing material 18 and the joint member 14 are arranged between the outward flange 9 and the mounting fin 8 on the outer peripheral surface of the profile 13, and the silicon material 19 is a panel fixing fin on the inner peripheral surface of the profile 13. 10 and the rising portion 12 a of the pressing edge fixing fin 12.

  The position of the joint surface 16 may be any as long as it is other than the lowermost part of the sash frame 4. If there is a joint surface 16 at the lowermost part of the sash frame 4, water accumulates in a notch 17 provided in the middle of the joint surface 16, and this water permeates again into the joint surface 16 on the indoor side by capillary action and enters the indoor side. There is a risk of intrusion, but this is unlikely to occur except at the bottom. In the illustrated example, the joining surfaces 16 are arranged at the left and right side positions of the sash frame 4. In this case, it is preferable that a notch 17 is formed at least on the lower side of the joint surface 16 in order to drain water downward by gravity as indicated by an arrow. For example, the notches 17 may be provided on both upper and lower sides of the joint surface 16 as shown in FIG. 6, or the notches 17 may be provided only on the lower side of the joint surface 16 as shown in FIG.

  The said panel 5 is glass, for example, and is formed in disk shape. In the illustrated example, a multi-layer glass with high heat insulation is used as the panel 5. In order to mount the panel 5 in the sash frame 4 from the indoor side, the inner diameter of the panel fixing fin 10 is smaller than the outer diameter of the panel 5, and the inner diameter of the pushing edge fixing fin 12 including the locking portion 42 described later is the panel 5. Is set larger than the outer diameter. A spacer 20 on which the panel 5 is placed is disposed between the panel fixing fin 10 and the rising edge 12 a of the pressing edge fixing fin 12 at the lower part in the sash frame 4.

A dry water-stopping material 22 that seals between the panel fixing fin 10 and the panel 5 is provided to form a double seal structure. The indoor / outdoor seal structure of the panel 5 is a caulking-less, that is, a dry seal structure that does not use a wet seal material, thereby improving workability and shortening the work period.

  The pushing edge 6 is formed in an annular shape, and is divided into a plurality of, for example, upper and lower parts in the circumferential direction so that it can be easily detached from the sash frame 4. In the illustrated example, the pressing edge 6 is made of a synthetic resin shape as a heat insulation type, but may be made of a metal shape such as aluminum as a non-heat insulation type (spread type) (not shown). The pushing edge 6 can select either a heat insulating type or a non-insulating type. An indoor side packing 23 made of a soft resin that seals the space between the panel 5 is mounted on the inner peripheral edge of the outer edge of the push edge 6, and the indoor packing 23 is locked to the inner peripheral edge of the outer edge of the push edge 6. A locking portion 24 for projecting is provided.

  Between the lower edge of the indoor surface of the panel 5 and the indoor side packing 23, the dew condensation water that is generated on the indoor surface of the panel 5 and flows down in the sash frame 4 (panel fixing fin 10 and pressing edge fixing fin). For example, a rod-shaped condensation drainage member 25 having a substantially eight-shaped cross section and a sharp tip is inserted and attached to create a gap for drainage at the lower portion of the space between the 12 rising portions 12a. Further, at the lowermost part of the panel fixing fin 10 of the sash frame 4, water that is drained from the notch 17 or drained from the condensation drainage member 25 and collected in the lower part of the sash frame 4 is drained to the outside. A drain valve 26 is provided. Specifically, a drainage hole 27 that communicates the inside of the sash frame 4 and the outside is provided at the lowermost part of the panel fixing fin 10, and a drainage valve 26 is attached to the drainage hole 27. The drain valve 26 is composed of a substantially cylindrical main body and a water stop valve (check valve) provided in the main body. The water stop valve is closed by wind pressure from the outside of the room, so that the back flow of drainage is prevented. It is to be prevented.

  The pressing edge 6 is fastened and fixed to the inner periphery of the sash frame 4, specifically, to the inner peripheral surface of the extending portion 12 b of the pressing edge fixing fin 12 with a fixing tool such as a screw (screw) 11. The screw 11 is screwed substantially perpendicularly to the extending portion 12 b of the pressing edge fixing fin 12. On the inner periphery of the sash frame 4, specifically, on the inner peripheral surface of the extending portion 12 b of the pressing edge fixing fin 12, as shown in FIG. 8, a locking portion 42 for positioning and locking the pressing edge 6, An inclined portion 29 is provided for urging the pushing edge 6 toward the locking portion 42 using the tightening force of the screw 11. The locking portion 42 is provided on an extension of the rising portion 12a.

The pushing edge 6 is preferably provided with an inclined portion 30 corresponding to the inclined portion 29. The pressing edge 6 is urged toward the panel 5 by the inclined portion 29 when the screw 11 is fastened and fixed, whereby the pressing edge 6 is tightly pressed and positioned by the locking portion 42 via the tape-shaped sealing material 28. Thus, the mounting accuracy of the pressing edge 6 can be improved, and the airtightness and watertightness (waterproofness) between the pressing edge 6 and the sash frame 4 can be improved.

  A frame angle member 32 for fixing the outdoor edge of the frame 31 is detachably provided on the outer peripheral side (the outer periphery in the illustrated example) of the pushing edge 6. That is, as shown in FIG. 1, the frame 3 is attached to the opening 3 of the housing 2 by attaching a thin frame 31 made of synthetic resin, for example, or as shown in FIG. An opening frame 33 having an inner peripheral wall 33a that is substantially the same as the surface or slightly larger in inner diameter is provided, and a cloth material (wallpaper or wall cloth) is pasted from the wall surface of the inner wall material 39 to the inner peripheral wall 33a of the opening frame 33. The frame angle member 32 can be attached to and detached from the outer peripheral side of the pushing edge 6 so that any one of the cross fits to be constructed can be selected. The frame 31 may be made of metal, for example, stainless steel. When selecting the frame fit, the frame angle member 32 is attached to the outer peripheral side of the pushing edge 6, and when selecting the cross fit, the frame angle member 32 is not attached to the outer peripheral side of the pushing edge 6. For this reason, in the case of a cross fit, there is no frame angle member 32, so that the pushing edge 6 can be easily removed by moving it inward in the radial direction.

  Further, in order to enable the frame angle member 32 to move inward in the radial direction in this way, a gap S is provided between the end portions of the pressing edge 6 divided in the vertical direction, and between the end portions, between the end portions. A synthetic resin push-edge linking member (also referred to as a cap) 34 is disposed to fill the gap S between the ends and connect the ends, and the push-edge linking member 34 is formed in the extension portion 12 b of the push-edge fixing fin 12. It is detachably attached to the peripheral surface by a fixing tool such as a screw 35. The push-edge connecting member 34 integrally has an angle connecting portion 34a that connects between the end portions of the frame angle member 32 in the case of the frame fitting, but does not have the angle connecting portion 34a in the case of the cross fitting. .

  In order to detachably and easily attach the frame angle member 32 to the outer peripheral side of the pressing edge 6, an engagement receiving portion 36 having a substantially C-shaped cross section is formed on one of them, for example, the outer peripheral side of the pressing edge 6. On the other hand, for example, the frame angle member 32 is formed with an engagement portion 37 having a substantially T-shaped cross section that engages with the engagement receiving portion 36. The frame angle member 32 is formed in a long plate shape or a band shape made of, for example, semi-rigid resin having flexibility, and is formed to have substantially the same length as the outer circumference of each pressing edge 6 divided vertically.
