Description

[Technical Field]

[0001] The present invention relates to a method for manufacturing a projection window. [Background technology]

[0002] 2. Description of the Related Art Projection windows have been known in the past, in which glass is fixed in a glass receiving groove of a frame with a sealant. However, there is a demand for improved manufacturability of such projection windows. Summary of the Invention [Problem to be solved by the invention]

[0003] SUMMARY OF THE INVENTION In view of the above-mentioned circumstances, an object of the present invention is to provide a method for manufacturing a projection window that is easy to manufacture. [Means for solving the problem]

[0004] In order to achieve the above object, the manufacturing method of a protruding window according to the invention described in claim 1 is characterized in that a shoji screen before the glass is installed is placed in the frame, and a jig whose height can be changed by rotating it around an axis in the forward direction is installed from the inside of the room in a low height in the gap between the upper surface of the bottom frame or transom and the underside of the bottom sill, and when the jig is rotated around the axis in the forward direction, the height of the jig increases, maintaining the underside of the bottom sill at the appropriate height, and the glass is placed in the shoji screen and fixed in the glass swallowing groove of the sill with a sealant. [Effects of the Invention]

[0005] The manufacturing method for a projection window according to the invention described in claim 1 involves placing a shoji screen before the glass is installed within the frame, and installing a jig, which can be adjusted in height by rotating it around an axis in the forward direction, in the gap between the top surface of the bottom frame or transom and the underside of the bottom frame from the inside of the room in a low height state; when the jig is rotated around an axis in the forward direction, the height of the jig increases, maintaining the underside of the bottom frame at the appropriate height; placing the glass in the shoji screen and fixing the glass in the glass-swallowing groove of the frame with a sealant prevents the bottom frame from sagging under its own weight or the weight of the glass while the sealant is curing; and since the jig can be installed from the inside of the room, it is easy to manufacture.

[Figure 7] FIG. 10 is a vertical cross-sectional view showing another embodiment of the projection window according to the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0007] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Figures 5 and 6 show one embodiment of a projection window according to the present invention. This projection window is applied to a sash for a building, and comprises a frame 1 attached to an opening in the building frame, and a shoji screen 3 housed within the frame 1 so that it can be opened and closed freely.

[0008] The frame 1 is made up of an upper frame 11, a lower frame 4, and left and right vertical frames 12, 12, all of which are made of extruded aluminum alloy material, forming a framework around all four sides. The shoji screen 3 is constructed by assembling an upper frame 13, a lower frame 6, and left and right vertical frames 14, 14 made of extruded aluminum alloy on all four sides, and fitting glass (double-glazed glass) 2 inside them. Pivot hinges 15 are attached to the upper part of the exterior side of the left and right vertical frames 12, 12, and the shoji screen 3 is attached to the frame 1 by the pivot hinges 15. The shoji screen 3 opens by rotating with the shaft 16 of the pivot hinge 15 as a fulcrum so that the lower part protrudes outside the room.

[0009] As shown in Figures 5 and 6, each frame 6, 13, and 14 of the shoji screen 3 has a glass groove 9 that opens on the inner periphery. The peripheral edge of the glass 2 is inserted into the groove 9, and a wet sealant 10 is filled in the gap between the exterior wall 9a of the groove 9 and the exterior side of the glass 2, and in the gap between the interior wall 9b of the groove 9 and the interior side of the glass 2. The glass 2 is then attached to the groove 9 of the frame 6, 13, and 14 by bonding it with the sealant 10. Reference numeral 29 in the figure denotes a backup material that receives the sealant 10. The exterior wall 9a of the groove 9 of the lower frame 6 and the vertical frame 14 forms a removable edge. Two setting blocks 17 are provided at the bottom of the groove 9 of the lower frame 6, one on each side, to receive the glass 2. In this shoji screen 3, the visible dimensions of each frame 6, 13, 14 are made as small as possible by not providing a hollow portion in the visible wall 9c, which corresponds to the bottom wall of the glass swallowing groove 9 of each frame 6, 13, 14, and the frames 6, 13, 14 are adhered to the glass 2 with a sealant 10 to ensure sufficient strength. The frames 6, 13, 14 of the shoji screen 3 are hidden by the frame 1 when viewed from inside the room.

[0010] In this projection window, when the sealant 10 that bonds the glass 2 to the frames 6, 13, and 14 is cured, a jig 8 is attached to the gap 7 between the upper surface 4a of the frame 4 and the lower surface 6a of the frame 6, as shown in Figure 5, to prevent the frame 6 from bending downward due to its own weight or the weight of the glass 2. The jig 8 is integrally formed with a base portion 18 that is placed in the gap 7 between the upper surface 4a of the frame 4 and the lower surface 6a of the frame 6, and an operating portion 19 that extends from the base portion 18 through the gap between the frame 4 on the indoor side of the frame 6 in the prospective direction to the inner periphery of the shoji screen 3. The jig 8 is molded as a single piece from hard resin.

[0011] As shown in FIG. 3, the base portion 18 is formed in the shape of a block with a generally rectangular cross section extending in the indoor / outdoor direction, with a vertical dimension Y greater than a horizontal dimension X. The vertical dimension Y is the same as or slightly smaller than the design dimension of the gap 7 between the upper surface 4a of the lower frame 4 and the lower surface 6a of the lower frame 6. Specifically, the design dimension of the gap 7 between the upper surface 4a of the lower frame 4 and the lower surface 6a of the lower frame 6 is 10.5 mm, and the vertical dimension Y of the base portion 18 is 9.5 mm, which is 1 mm smaller than that dimension. The horizontal dimension X of the base portion 18 is 8 mm, which is 1.5 mm smaller than the vertical dimension Y. The corner 22a of the base portion 18 between the left side surface 20 (hereinafter, "left" and "right" refer to "left" and "right" as viewed from the indoor side) and the upper surface 21, as well as the corner 22b between the right side surface 23 and the lower surface 24, are chamfered in an R-shape. The outside end of the left side surface 20 of the base portion 18 is provided with a tapered portion 25 that is inclined so that the horizontal dimension X decreases toward the outside of the room. Operating unit 19 is formed as a thin plate of a fixed width, extending diagonally to the left at 45° from the end of base unit 18 on the indoor side. An extension 28 extending horizontally to the left is formed at the tip of operating unit 19, and a label displaying warnings to prevent unauthorized removal of jig 8 is affixed to the indoor side of extension 28. In addition, a hole 26 is formed at the tip of operating unit 19, and by passing a wire or the like through hole 26 and tying the wire or the like to something or taping it to frame 1, it is possible to prevent jig 8 from falling outside when opening shoji screen 3, for example. A padding 27 is applied to the inside corner between the base part 18 and the operating part 19, thereby preventing the base of the operating part 19 from being damaged when the operating part 19 is operated to rotate the base part 18.

[0012] When attaching or detaching the jig 8, as shown in FIG. 1(a), it is rotated 90° so that the right side surface 23 abuts against the upper surface 4a of the lower frame 4. At this time, the base portion 18 is in a low position, the operating portion 19 is tilted 45° to the right, and the extension portion 28 extends upward. When filling and curing the sealant 10, the operating portion 19 is rotated 90° counterclockwise around the axis extending in the indoor / outdoor direction by placing a hand on it and moving it to the left, thereby placing the base portion 18 in the position shown in FIG. 1(b). This raises the height of the base portion 18, keeping the lower surface 6a of the lower frame 6 at the appropriate height and preventing the lower frame 6 from sagging due to its own weight or the weight of the glass 2.

[0013] Next, we will explain the manufacturing procedure for this projection window. First, the frame 1, which is made up of the upper frame 11, the lower frame 4, and the left and right vertical frames 12, 12, is attached to the opening in the main body. Next, the upper frame 13, the lower frame 6, and the left and right vertical frames 14, 14 are assembled, and the shoji screen 3 in its state before the glass 2 is inserted is attached to the frame 1 with a pivot hinge 15. Next, with the shoji screen 3 open, as shown in Figure 2(a), place the two jigs 8, 8 side by side near the center of the top surface of the lower frame 4 in the previously described posture for attachment and detachment (with the base portion 18 at a low height). Then, close the shoji screen 3 while holding the jigs 8, 8 by hand. Next, as shown in FIG. 2(b), the operator places his / her hands on the operating portion 19 and slides the jigs 8, 8 until the base portion 18 is positioned directly below the setting blocks 17, 17. Next, as shown in Figure 2(c), by placing your hand on the operating part 19 and moving it to the left, you rotate the base part 18 counterclockwise by 90° around the axis facing the interior / exterior direction. This operation is performed while manually pulling the shoji screen 3 toward the interior of the room. By rotating the jig 8 in this way, the height of the base part 18 of the jig 8 increases, and the underside 6a of the bottom frame 6 is held at the appropriate height. In this state, the ridges (outdoor-side walls 9a of the glass-swallowing grooves 9) of the bottom frame 6 and vertical frames 14, 14 are removed, the glass 2 is placed in the shoji screen 3, and after attaching the ridges 9a, a backup material 29 is inserted into the gap between the glass-swallowing grooves 9 of the frames 6, 13, 14 and the glass 2, and the inner periphery of the backup material 29 is filled with the sealant 10. Once the sealant 10 has hardened, place your hand on the operating part 19 and move it to the right, rotating the base part 18 90° clockwise around the axis facing the indoor / outdoor direction. This lowers the height of the base part 18 (see Figure 1(a)), allowing you to open the shoji screen 3. Open the shoji screen 3 and remove the jigs 8, 8. At this time, the left side surface 20 of the base part 18 is facing up, and because the tapered part 25 is provided at its outdoor end, when the shoji screen 3 is opened, the indoor-side corner of the lower frame 6 rubs against the base part 18, pulling the jig 8 to the outdoor side, preventing the jig 8 from falling out.

[0014] One way to prevent the sill 6 from bending while the sealant 10 is being cured is to drive a wedge into the gap 7 between the upper surface 4a of the sill 4 and the lower surface 6a of the sill 6 from outside the room, but driving a wedge from outside the room is not easy, and removing the wedge after the glass 2 has been inserted and the sealant 10 has been cured requires the worker to go outside, which is even more difficult. When using this jig 8, the jig 8 can be attached and removed from inside the room, eliminating the need for the worker to go outside, making it easier to work.

[0015] Figure 7 shows another embodiment of the projection window according to the present invention. This projection window is also applied to a sash for a building, and the frame 1 has a transom 5 installed between the left and right vertical frames 12, 12, near the upper frame 11. The opening below the transom 5 is fitted with glass 30 to form a fixed window, and the opening above the transom 5 is fitted with a shoji screen 3 that can be opened and closed freely using a pivot hinge 15 to form a projection window. As in the embodiment described above, when curing the sealing material 10 that adheres the glass 2 to the glass swallowing groove 9 of the frames 6, 13, and 14, a jig 8 is placed in the gap 7 between the upper surface 5a of the lintel 5 and the lower surface 6a of the lower frame 6 to prevent the lower frame 6 from bending.

[0016] As described above, in the manufacturing method of this projection window, the shoji screen 3 is placed in the frame 1 in a state before the glass 2 is attached, and a jig 8, which can be adjusted in height by rotating it about an axis in the forward direction, is attached from the inside of the room in a low height into the gap 7 between the upper surface 4a, 5a of the bottom frame 4 or transom 5 and the underside 6a of the bottom frame 6, and when the jig 8 is rotated about an axis in the forward direction, the height of the jig 8 increases, holding the underside 6a of the bottom frame 6 at the appropriate height.The glass 2 is then placed in the shoji screen 3 and fixed in the glass swallowing groove 9 of the frame 6, 13, 14 with sealant 10, which prevents the bottom frame 6 from sagging under its own weight or the weight of the glass 2 while the sealant 10 is curing, and moreover, the jig 8 can be attached from the inside of the room, making it easy to manufacture. In addition, this method of manufacturing a projection window allows the jig 8 to be easily installed in a position that most effectively prevents the lower frame 6 from bending by sliding the jig 8 in the longitudinal direction of the lower frame 4 or the lattice 5 and placing it directly below the setting block 17 of the lower frame 6. The jig 8 has a base portion 18 with different vertical and horizontal dimensions X and Y that is placed in the gap 7 between the upper surface 4a, 5a of the bottom frame 4 or transom 5 and the underside 6a of the bottom stile 6, and an operating portion 19 that extends from the gap in the indoor / outdoor direction between the bottom frame 4 or transom 5 and the bottom stile 6 to the inner periphery of the shoji screen 3, so that the jig 8 can be easily rotated around an axis in the prospective direction, and the height of the jig 8 can be reliably changed by rotating it. The jig 8 has a corner 22b chamfered in an R shape between the surface (right side surface 23) that is underneath when the jig is attached or detached from the base portion 18 and the surface (bottom surface 24) that is underneath when the sealing material 10 is cured, making it easy to rotate the base portion 18 around the axis in the prospective direction, and since the corner adjacent to corner 22b is not chamfered, it is difficult to rotate in the opposite direction. The jig 8 has a tapered portion 25 formed at the outdoor end of the surface (left side surface 20) that faces upward when attaching or detaching, so that when the shoji screen 3 is opened after the sealing material 10 has cured, the indoor corner of the lower frame 6 rubs against the base portion 18, pulling the jig 8 to the outdoor side, preventing the jig 8 from falling off to the outdoor side.

[0017] The present invention is not limited to the above-described embodiment. The jig only needs to have a part whose height changes when rotated around an axis in the projection direction, and the specific shape and material can be changed as appropriate. The shape and material of the frame and shoji screen, and the form of the hinge that attaches the shoji screen to the frame, etc. are arbitrary. [Explanation of symbols]
