Description

  The present invention relates to a sash in which a shoji is rotated around a peripheral edge to open and close an opening.

  Conventionally, in order to connect a shoji to a frame in an open window such as an overturned window, a component hinge 90 is generally used as shown in FIG. Since the component hinge 90 must be fixed to the shoji 91 and the frame 92 with a large number of screws 93a and 93b (usually five each), the workability when attaching the shoji 91 to the frame 92 is very high. bad.

  As another conventional example, there is a structure using a shape hinge 94 as shown in FIG. In this structure, a rail 96 for connecting the shoji 91 is integrally formed on the upper surface of the lower frame 95, and as shown in FIG. 97 is engaged from the outdoor side, and after the shoji 91 is raised, a slip-off prevention component 98 is attached to the lower frame 95 so that the shoji 91 is not detached. According to this structure, it is easier to install the shoji 91 in the frame 92 than when a hinge is used. However, a special lower frame 95 is required to integrally form the shoji connection rail 96 in the lower frame 95. Thus, there is a disadvantage that the lower frame 95 cannot be used in combination with other window types (for example, a vertical sliding window, a protruding window, etc.). In addition, a notch or hole for drainage must be additionally formed in the rail 96 of the lower frame 95.

  In the door described in Patent Document 1, the suspension side vertical frame 5 is constituted by a vertical frame base 6 and a vertical frame attachment 9, and the suspension side vertical rod 24 of the door is rotatably connected to the vertical frame attachment 9. ing. The vertical frame base 6 has a C-shaped groove 8 on the inner peripheral side, the vertical frame attachment 9 has a locking protrusion 11 protruding forward and backward, and the vertical frame attachment 9 is attached when the door is attached to the frame. It is attached in advance to the hanging rod side vertical shaft 24 of the door, and the locking protrusion 11 of the vertical frame attachment 9 is fitted into the C-shaped groove 8 of the vertical frame base body 6 in the forward and backward direction, and the screw 13 is used. It is fixed. Since the vertical frame attachment 9 has a curved wall that swells on the inner peripheral side, it is necessary to take a wide space between the vertical frame and the shoji of the shoji to dispose the vertical frame attachment 9, and the size of the vertical frame attachment 9 is large. Become. Further, when fixing the vertical frame attachment 9 with the screw 13, it is necessary to make a hole in the curved wall and insert the screw 13 through the hole. It takes time and effort. Furthermore, it is not easy to fit the locking protrusion 11 of the vertical frame attachment 9 into the C-shaped groove 8 of the frame in the front-rear direction while supporting the heavy door by hand.

  The skylight described in Patent Document 2 has a substantially crank shape in which the hinge receiving member 10 that rotatably connects the shoji has a main locking portion 42 that is bent toward the inner peripheral side and a sub-locking portion 43 that is bent toward the outer peripheral side. The main locking part 42 and the secondary locking part 43 are locked to the window frame member from the axial direction. In this case, the hinge receiving member 10 needs to be attached to the window frame in advance before the window frame is framed. The hinge receiving member 10 is first attached to the shoji, and the hinge receiving member 10 is later attached to the window frame. Since it cannot be attached to, the workability is poor.

As shown in FIG. 1, the lower frame 7 has a connecting material mounting portion 4 formed in a middle portion in the vertical direction parallel to the prospective direction, that is, horizontally. The connecting material mounting portion 4 has a plate shape in which the outdoor half portion 4a protrudes to the outdoor side, and a space 11 is formed below the outdoor side. The outdoor side end portion 4b of the connecting material mounting portion 4 is bent downward. A protrusion 13 protruding outward is formed at the lower part of the finding surface 12 that rises upward from the indoor side end of the connecting material mounting portion 4. Between the protrusion 13 and the connecting material mounting portion 4, a protrusion 13 is formed. An engagement groove 5 having a substantially U-shaped cross section that is open on the outdoor side is formed, and the indoor side end 3 a of the connecting member 3 is engaged with the engagement groove 5.

  The connecting member 3 is formed of an extruded shape of an aluminum alloy, and as shown in FIG. 1, a plate-like portion 14 disposed on the upper surface of the connecting member attaching portion 4 of the lower frame 7, and a plate-like portion 14 has a shaft portion 8 formed by taking it upward from the outdoor side end portion of the 14, and a hook-like portion 15 that hangs downward from the outdoor side end portion of the plate-like portion 14, and whose distal end portion is bent toward the indoor side. . The shaft portion 8 has a C-shaped cross section that is open at an oblique lower side on the outdoor side. The hook-shaped portion 15 forms an engagement groove 6 having a substantially U-shaped cross section that is open on the interior side between the lower surface of the plate-shaped portion 14, and the connection member mounting portion 4 of the lower frame 7 is formed in the engagement groove 6. The outdoor end 4b is engaged. That is, the connecting member 3 is engaged with the lower frame 7 over the entire length of the indoor and outdoor edges. As shown in FIGS. 2 and 3, the connecting member 3 has substantially the same length as the lower collar 16 of the shoji 2, and the two left and right end portions are fixed to the connecting member attaching portion 4 of the lower frame 7 with screws 17. It is. As shown in FIG. 1, the screw 17 is located closer to the outdoor side, and the lower side of the screw 17 is a space 11 that is open to the outdoor side. Therefore, even if rainwater enters from the screw hole, the lower frame 7. It is drained to the outside along the top surface. Also, as shown in FIG. 2, the connecting material 3 is substantially the same length as the lower rod 16, and the left and right sides of the upper surface of the lower frame 7 are vacant. It drains to the outside along the left and right sides of the upper surface of the lower frame 7.

  The shoji 2 is composed of an upper rod 19 and a lower rod 16 formed of an extruded shape of an aluminum alloy, and four left and right rods 20 and 20 which are assembled into a glass 21 in a groove 21 formed on the inner peripheral side of each rod. The peripheral edge of the panel 22 is fitted and fixed. As shown in FIG. 1, the lower collar 16 is formed with a fitting portion 23 that fits around the shaft portion 8 of the connecting member 3 at the lower edge portion. The fitting portion 23 is formed in a substantially C-shaped cross section having an opening 24 on the indoor side, covers the periphery of the shaft portion 8 by 180 ° or more, and further on the opening edge of the shaft portion 8 and the fitting portion 23. The formed projections 30 a and 30 b are locked so that the shaft portion 8 fitted in the fitting portion 23 does not come out of the opening 24. Moreover, the opening part 24 of the fitting part 23 is set so that the range which the shoji 2 rotates may be regulated to 0-90 degrees. Before assembling the shoji 2, the connecting member 3 is attached to the fitting portion 23 of the lower rod 16 by fitting the shaft portion 8 from the longitudinal direction in advance. As shown in FIG. 3, end caps 25 are fitted into the upper and lower ends of the collar 20, and the connecting member 3 is sandwiched between the end caps 25 of the left and right collars 20 to prevent them from coming off.

  As shown in FIG. 1, an operator device 26 made of a pulley and a wire is provided in the space between the inner peripheral prospective surface of the upper frame 9 and the outer peripheral prospective surface of the upper collar 19. Further, a damper 27 is attached between the collar frame 10 and the collar 20 as shown in FIG. The shoji 2 can be opened by the force of the damper 27 by operating an operation button (not shown), and the shoji 2 can be closed by the operator device 26.

  Next, the procedure for attaching the shoji 2 to the frame 1 will be described. In the shoji 2, the connecting member 3 is pivotally attached in advance by fitting the shaft portion 8 to the fitting portion 23 of the lower arm 16, and as shown in FIG. The connecting member 3 is arranged on the connecting member attaching portion 4 so as to slide in the indoor direction from the outdoor side. Then, as shown in FIG. 4B, the indoor side end portion 3 a of the connecting material 3 is engaged with the engaging groove 5 formed in the indoor side end portion of the connecting material mounting portion 4, and the connecting material 3 is formed. The outer end 4b of the connecting member mounting portion is engaged with the engaging groove 6 thus formed, and in this state, the connecting member 3 is fixed to the connecting member mounting portion 4 with two screws 17 from the inner peripheral side.

  As described above, this sash forms the vertical force such as the weight of the shoji 2 and the lifting force of the wind tilt and the damper 27 on the indoor side of the connecting material mounting portion 4 and the outdoor side of the connecting material 3. The connecting member 3 is received and restrained in a state where it is in contact with the connecting member mounting portion 4, and the screw 17 is used to generate wind resistance (negative pressure) in the outdoor direction by a shearing force. Since it is only a role to receive, the number of screws 17 can be reduced. When using a component hinge, it is necessary to drive about 10 screws into the lower frame 7. However, since only 2 screws 17 are required in this sash, workability when attaching the shoji 2 to the frame 1 is great. improves. Further, when attaching the shoji 2 to the frame 1, the connecting material 3 is slid on the connecting material attaching plate portion 4 from the outdoor side to the indoor direction so that the indoor side end 3 a of the connecting material 3 is connected to the connecting material attaching portion 4. The engaging groove 5 allows the outer end 4b of the connecting member mounting portion 4 to be easily engaged with the engaging groove 6 of the connecting member 3, respectively, whereby the connecting member 3 is attached to the connecting member mounting portion 4 of the frame. And can be held in a state of being positioned in the indoor / outdoor direction, the attachment work of the connecting member 3 to the frame is easy. In addition, the processing of the lower frame 7 can be simplified since the processing of the screw holes in the lower frame 7 is only required in two places and there is no need to provide a notch for drainage. Since the connecting material 3 is plate-shaped, the connecting material 3 can be easily disposed without widening the space between the lower frame 7 and the lower collar 16, and the connecting material 3 is fixed to the lower frame 7 with screws 17. It is easy. Further, the connecting member 3 is fixed to the outdoor half portion 4a of the connecting member mounting portion 4 formed in a plate shape projecting to the outdoor side with a screw 17, and the outer side of the screwed portion is open on the outdoor side. Therefore, rainwater that has entered from the screw hole does not enter the lower frame, and there is no need to stop water around the screw hole.

  Furthermore, this sash differs from the conventional shape hinge system by not providing a rail for connecting the shoji to the lower frame 7, so that the frame 1 for the overturned window can be slid out, a protruding window, an outer window, etc. Can be shared. FIG. 5 shows a connecting portion between the lower frame 7 and the shoji 2 in the case of a vertical sliding window. In the case of the vertical sliding window in this way, a metal fitting (friction stay) 28 for supporting the shoji 2 is attached instead of attaching the connecting material 3 to the connecting material attaching portion 4 of the lower frame 7. Since the engagement groove 5 on the lower frame 7 side is provided at the indoor side end portion of the connecting material mounting portion 4, it does not interfere with the mounting of the metal fitting 28. Further, the space below the screw 29 for fixing the metal fitting 28 to the lower frame 7 is a space 11 opened to the outdoor side, so there is no need to stop water around the screw 29.

  FIG. 6 shows another embodiment of the connecting portion between the shoji 2 and the frame 1. In the lower frame 7, the engagement groove 5 is formed in a substantially U-shaped cross section in which the outdoor side opens on the indoor-side finding surface 12 of the connecting material mounting portion 4. The connecting member 3 is formed in a shape in which the indoor side end 3 a is bent in a crank shape on the inner peripheral side, and is engaged with the engaging groove 5 of the lower frame 7. Even when formed in this way, the connecting member 3 is slid in the indoor direction so that the indoor side end portion 3a of the connecting member 3 is engaged with the engaging groove 5 of the lower frame 7 and the weight of the shoji 2 causes the connecting member. The engagement groove 5 can restrict the indoor side end portion 3a of the vehicle 3 from being lifted. Further, since there are no protrusions on the connecting member mounting portion 4 and the finding surface 12 of the lower frame 7, it is easy to attach components such as a friction stay to the lower frame 7 in order to use the lower frame 7 as a sliding window.

  FIG. 7 shows still another embodiment of the connecting portion between the shoji 2 and the frame 1. The lower frame 7 has an engagement groove 5 formed in a substantially U-shaped cross section with an inner peripheral side opening at an indoor side end of the connecting material mounting portion 4. The connecting member 3 is formed in a shape in which the indoor side end portion 3 a is bent at right angles to the outer peripheral side, and is engaged with the engaging groove 5 of the lower frame 7. In the present embodiment, when the connecting member 3 is attached to the connecting member attaching portion 4, as shown in FIG. 7B, the outdoor end 4 b of the connecting member attaching portion 4 is formed in the engaging groove 6 of the connecting member 3. First, the connecting member 3 is rotated to the outer peripheral side with the outdoor side end portion 4b of the connecting member mounting portion 4 as a fulcrum, and the indoor side end portion 3a of the connecting member 3 is engaged with the engaging groove of the lower frame 7. 5 is engaged. Thereafter, the connecting member 3 is fixed to the connecting member attaching portion 4 with screws 17. According to the present embodiment, the engagement groove 5 is formed so as to open to the inner peripheral side, so that the connection member 3 tries to move in the indoor / outdoor direction due to wind pressure or the like applied to the shoji 2. 5 can be regulated. Similarly to the embodiment of FIG. 6, since there are no projections on the connecting member attaching portion 4 and the finding surface 12 of the lower frame 7, it is easy to attach components such as a friction stay to the lower frame 7.

FIG. 8 shows still another embodiment of the connecting portion between the shoji 2 and the frame 1 and shows an example in which the shoji 2 is applied to an inward-turning window that is rotated and opened indoors. The connecting member 3 is plate-shaped, and has a shaft portion 8 that protrudes upward, and has an engagement groove 6 having a substantially U-shaped cross section that opens to the indoor side end portion on the outdoor side. The lower frame 7 is provided with a connecting member mounting portion 4 horizontally on the inner peripheral side, and has an engagement groove 5 having a substantially U-shaped cross section that is open at the indoor side at the outdoor end of the connecting member mounting portion 4. ing.
When the shoji 2 is attached to the frame 1, the connecting member 3 is preliminarily connected with the shaft portion 8 fitted to the fitting portion 23 of the lower rod 16 so that the connecting member 3 can be freely rotated. The outer end 3b of the connecting member 3 is inserted into the engaging groove 5 formed at the outer end of the connecting member mounting portion 4 and the connecting member 6 is connected to the engaging groove 6 formed in the connecting member 3. The indoor side end portions 4c of the attachment portions are engaged with each other. Thereafter, the connecting member 3 is fixed to the connecting member mounting portion 4 with screws 17 from the inner peripheral side. In the case of the present embodiment, similarly to the embodiment of FIG. 1, the frame 1 of the shoji 2 can be easily attached, and the engagement grooves 5 and 6 on the indoor side and the outdoor side are used in the vertical direction. Since the force is received, the number of screws 17 can be reduced.

  The present invention is not limited to the embodiments described above. The connecting material 3 can be arranged on the upper frame 9 to be a protruding window, or the connecting material 3 can be arranged on the eaves frame 10 to make an outer window or an inner window. The engagement groove 5 of the frame can be omitted. The form of the engaging part on the outdoor side and the indoor side of the connecting member 3 can be changed as appropriate. In order to fix the connecting member 3 to the frame 1, a fixing tool (for example, a rivet) other than a screw can be used.
