  Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 to 6 show an embodiment of a fitting according to the present invention. This fitting is a raising and lowering window installed in a window opening of a house, and as shown in FIGS. 1 to 4, is disposed on a frame 1 fixed to a skeleton opening and an upper side of an outdoor side in the frame 1. An outer sash 4, an inner sash 2 disposed below the indoor side in the frame 1, and left and right balancers 3 and 3 installed in the frame 1 are provided. The outer sash 4 is a fixed sash fixed to the frame 1. The inner shoji 2 is a movable shoji that slides up and down along the vertical frames 5 and 5. As shown in FIG. 4, the inner sash 2 is suspended by wires 6, 6 extending from the balancers 3, 3, and can be slid up and down with a light force, and can be stopped at an arbitrary height position. . In addition, the inner sash 2 has latches 7, 7 on the left and right sides on the upper side for engaging with the vertical frames 5, 5, and when the latches 7, 7 are released, the inner sash 2 can be tilted indoors as shown in FIG. Thus, the inner sash 2 can be easily cleaned. The side portions of the inner sash 2 and the vertical frames 5 and 5 are connected by arms 8, 8, and the arms 8, 8 regulate the falling angle of the inner sash 2.

  The frame 1 includes an upper frame 9, a lower frame 10, and left and right vertical frames 5 and 5. As shown in FIG. 1, the upper frame 9 is composed of two members, an outer peripheral member 11 and an inner peripheral member 12. The outer peripheral side member 11 is formed of an extruded member of an aluminum alloy. The inner peripheral side member 12 is formed of an extruded member made of a synthetic resin, is disposed on the indoor side of the upper frame 13 of the shoji, and covers a portion of the upper frame 9 that can be seen from the indoor side. The inner peripheral member 12 has locking portions 14a and 14b at two locations on the outside and indoor sides, and the locking portions 14a and 14b are fixed to the outer peripheral member 11 and attached. The inner peripheral side member 12 has an angle portion 16 which is screwed to the frame 15 on the indoor side, and a bottom wall 17 is formed flush with the angle portion 16 on the outside of the angle portion 16. Is located at substantially the same height as the lower end of the hanging piece 18 formed at the outdoor end of the outer peripheral side member 11. A flexible fin piece 19 is formed at the outdoor end of the bottom wall 17 so as to protrude to the outside of the room, and the tip of the fin piece 19 is in contact with the indoor side of the upper frame 13 of the shoji 4. The inside of the inner peripheral side member 12 is partitioned into a plurality of hollow portions 20a, 20b, 20c, and 20d, thereby enhancing heat insulation. As shown in FIG. 9 (a), the inner peripheral side member 12 has an L-shaped notch 21 so as to leave angle portions 16 at both left and right end portions so that the balancers 3 and 3 are inserted only into the upper frame 9. It is provided.

  As shown in FIG. 20, the inner peripheral side member 12 of the upper frame 9 can be formed with the angle portion 16 as a separate body. In this case, by simply cutting the left and right side edges 12a of the inner peripheral side member 12 straight, a hole for inserting the upper portion of the balancer 3 can be formed, and an L-shaped notch as shown in FIG. Since 21 is unnecessary, the processing cost can be reduced. In addition, since the inner peripheral side member 12 can be removed while the angle portion 16 is attached to the frame 15, the maintainability is improved.

As shown in FIG. 2, the vertical frame 5 has an outer peripheral member 22, an inner peripheral member 23, and an angle member 39. The outer peripheral member 22 is made of an extruded aluminum material, and the inner peripheral member 23 and the angle member 39 are made of an extruded synthetic resin material.
The outer peripheral side member 22 has a finding wall 24 on the outside of the room, and the finding wall 24 projects to the innermost side of the vertical frame 5, and the outer sash 4 is straight from the inside of the room with left and right arms. The tight material 25 is installed between the vertical frames 5 and 5 and provided on the outer peripheral portion of the outdoor side surface of the outer sash 4 and abuts on the indoor side at the tip of the finding wall 24. As described above, since the outer sash 4 can be built straight from the indoor side with the left and right helmets, it was conventionally necessary when the outer sash 4 was to be installed between the vertical frames 5 and 5 with the left and right sides. Since the space for the transfer is not required, the apparent size of the vertical frame 5 can be reduced, and as a result, the lighting area and the opening area increase in the left-right direction. A rectangular hollow portion 26 is provided on the indoor side of the finding wall 24.

As shown in FIG. 2, the inner peripheral member 23 of the vertical frame 5 is attached to the inside of the hollow portion 26 of the outer peripheral member 22 from the inner peripheral side. The inner peripheral side member 23 is provided below the balancer 3 as shown in FIGS. That is, the upper portion of the inner peripheral member 23 is shorter than the outer peripheral member 22 and is cut flat, thereby securing the mounting space 27 for the balancer 3 between the upper end of the inner peripheral member 23 and the lower surface of the upper frame 9. I have.
As shown in FIG. 2, the inner peripheral member 23 has a concave portion 28 that is concave on the outer peripheral side on the indoor side. The bottom of the concave portion 28 is an insertion portion 29 for the wire 6 that hangs the inner sash 2. Inwardly protruding portions 30a and 30b are provided on the inner and outer walls of the inner side of the wire insertion portion 29, respectively. As shown in FIG. The rod 31 is guided between the inward projections 30a and 30b. The lower end of the wire 6 is locked to the rod 31. The outdoor side of the concave portion 28 is partitioned into a plurality of hollow portions 32a, 32b, 32c, 32d.
As shown in FIG. 2, a hook-shaped locking piece 33 is formed on the inner peripheral side of the inward projection 30 a on the outdoor side. It has a guide groove 34a. A resin plate 35 is attached between the locking piece 33 and the inwardly protruding portion 30b on the indoor side. As shown in FIG. 6, the eye panel 35 is provided from below the balancer 3 to a height position overlapping the upper frame 36 of the inner shroud 2, and the wire insertion portion 29 is hidden behind the eye panel 35 so as to be invisible. . As shown in FIG. 18, the eye plate 35 locks the locking portion 37 formed at the outdoor end with the locking piece 33 of the vertical frame 5, and rotates around the outer circumference with the locking portion 37 as a fulcrum. By doing so, the locking piece 38 formed at the indoor side end is elastically locked and attached to the inwardly protruding portion 30 b of the vertical frame 5. When removing the eye plate 35, as shown in FIG. 6, the finger may be inserted into the lower end of the eye plate 35 and pulled inward while the inner sash 2 is depressed.

  As shown in FIGS. 2 and 3, an angle member 39 is attached to the indoor side of the inner peripheral member 23. The angle member 39 is attached to the locking grooves 40a, 40b formed in the outer peripheral member 22 and the inner peripheral member 23 by locking the locking pieces 41a, 41b from the inner peripheral side, respectively. The angle member 39 is formed of an extruded member made of a synthetic resin, and integrally has an angle portion 42 screwed to the frame 15 and a finding portion 43 extending to the inner peripheral side along the indoor side wall of the inner peripheral member 23. are doing. The finding portion 43 is formed in a hollow shape. At the inner peripheral side end of the finding portion 43, there is an indoor guide groove 34b whose outside is open. The indoor guide groove 34b is provided to face the outdoor guide groove 34a formed on the inner peripheral member 23, and is sandwiched between the outdoor guide groove 34a and the indoor guide groove 34b as shown in FIG. A slider 44 to which an arm 8 for restricting the angle of the inner sash 2 is set is slidably guided in a vertical direction. As shown in FIG. 2, the inner peripheral end 45 of the indoor guide groove 34 b is a sliding portion of a claw 46 of the latch 7 attached to the upper part of the inner sash 2. As shown in FIG. 9, the inner peripheral member 23 is cut under the balancer, while the angle member 39 extends to the lower surface of the upper frame 9. The inner peripheral member 23 and the angle member 39 of the vertical frame 5 are removable.

  In this way, by forming the vertical frame 5 by dividing it into the outer peripheral member 22 and the inner peripheral member 23, the upper inner periphery of the vertical frame 5 can be cut only by cutting the upper part of the inner peripheral member 23 flat. The mounting space 27 for the balancer 3 can be easily secured on the side surface. A concave portion 28 recessed to the outer peripheral side is formed on the indoor side of the inner peripheral side member 23, and a wire insertion portion 29 and a guide portion (inwardly facing) of the lower portion (rod rod 31) of the inner sash 2 from the bottom side to the entrance side of the concave portion 28. The protrusions 30a, 30b), the guides (guide grooves 34a, 34b) of the arm slider 44, and the guide (the inner peripheral end 45 of the angle member 39) of the upper part (latch 7) of the inner sash 2 are formed in this order. Thus, it is possible to configure a high-performance guide portion while keeping the apparent size of the vertical frame 5 compact. The angle member 39 is formed separately from the inner peripheral member 23, the angle member 39 is extended to the upper frame, and the inner peripheral end 45 of the angle member 39 is used as a guide portion for the upper part (latch 7) of the inner sash 2. Thus, the balancer 3 can be concealed by the angle member 39, and the upper part of the inner shoji 2 can be smoothly guided to the upper side beyond the lower end of the balancer 3. By forming the inner peripheral member 23 and the angle member 39 from resin, and further providing the hollow portions 32a, 32b, 32c, and 32d in these members, high heat insulating performance can be obtained. Furthermore, by attaching a resin plate 35 to the concave portion 28 of the inner peripheral side member 23 to hide the wire insertion portion 29, the heat insulation performance is further improved and the design is improved. Since the eye plate 35, the inner peripheral side member 23, and the angle member 39 are removable, the maintainability is good.

  7 and 9, the balancer 3 is attached to the upper inner peripheral side surface of the vertical frame 5, and more specifically, between the upper end of the inner peripheral member 23 of the vertical frame 5 and the upper frame 9. The vertical frame 5 is disposed in the space 27 between the exterior finding wall 24 and the interior finding portion 43 in the outer peripheral member 22 of the vertical frame 5, and is attached to the inner peripheral side surface of the outer peripheral member 22. As shown in FIGS. 8 and 9, the balancer 3 substantially fits on the outer peripheral side from the inner peripheral side edge of the indoor side finding portion 43 of the vertical frame 5, that is, within the apparent size of the vertical frame 5 on the indoor side. When viewed from the room side, the balancer 3 is hidden by the finding portion 43 of the angle member 39 and cannot be seen. Strictly speaking, components such as the tip of the main shaft 56, the ratchet 58, and the click 59 provided on the upper portion of the balancer 3 slightly protrude inward from the locating portion 43 of the angle member 39, but this portion will be described later. The cover 61 is covered and hidden by the stopper 69. Further, the entire balancer 3 is completely contained within the outside dimension of the vertical frame 5 (the outside dimension of the finding wall 24). As shown in FIG. 9, the balancer 3 is inserted into the upper frame 9 only by about 15 mm from the notch 21 formed at the end of the inner peripheral member 12 of the upper frame 9. 3, the lower end position is higher.

As shown in FIGS. 7, 10, and 11, the balancer 3 has a base member 47 formed of a synthetic resin disposed on the outer peripheral side, and a drum 50 for winding the wire 6 and a barrel 49 containing a mainspring spring 48 on the base member 47. And a metal plate 51 is attached to the base member 47 from the inner peripheral side so as to cover the barrel 49 and the drum 50 so that the respective axes are arranged vertically in the horizontal direction. The outer diameters of the barrel 49 and the drum 50 are substantially the same. A barrel gear 52 is provided on the outer peripheral side of the barrel 49, and a drum gear 53 is provided on the outer peripheral side of the drum 50. A linkage gear 54 is attached to the base member 47 so as to mesh with the barrel gear 52 and the drum gear 53. The rotary torque stored in the mainspring 48 is transmitted to the drum 50 via the linkage gear 54. By meshing the linkage gear 54 between the barrel gear 52 and the drum gear 53 in this manner, the barrel gear 52 and the drum gear 53 can be made small so as not to protrude from the outer periphery of the barrel 49 and the drum 50. The dimension in the expected direction can be reduced to just outside the barrel 49 and the drum 50. Conversely, the diameters of the barrel 49 and the drum 50 can be made as large as possible with respect to the expected dimensions of the vertical frame 5, whereby the balancer 3 can cope with a large load. The three gears 52, 53, 54 are arranged in a straight line on a vertical line, and the pitch circle diameters of the three gears 52, 53, 54 are the same. As a result, the torque borne by the gears 52, 53, 54 can be made uniform, smooth rotation can be ensured, and the durability of the gears 52, 53, 54 can be improved.
The diameter of the drum 50 decreases toward the inner peripheral side, and the claw 46 of the latch 7 of the inner sash 2 to be described later passes through the space 95 (see FIG. 12) formed by reducing the diameter. A groove 55 is provided. The gears 52, 53, 54 and the drum 50 are made of resin.
In the base member 47, the shaft 90 of the drum 50 and the shaft 91 of the linkage gear 54 are integrally formed on the bottom plate 89. As shown in FIG. 11, the base member 47 has a side wall 93 so as to cover the periphery of the case 92 of the metal barrel 49.

  At the upper part of the plate 51, a metal main shaft 56 is provided in engagement with the shaft 57 of the barrel 49. The main shaft 56 is provided with a ratchet 58, and a click 59 is formed on the plate 51 so as to mesh with the ratchet 58. It is provided. When a minus screwdriver is engaged with the main shaft 56 and rotated clockwise, the spring 48 is wound and the torque increases. When the click 58 is disengaged from the ratchet 58, the spring 48 returns and the torque decreases. I do. Further, on the plate 51, there is provided a counter 60 which moves in cooperation with the main shaft 56, and tightens and returns the main shaft 56 using the counter 60 as a guide so that the torque is balanced with the weight of the inner sash 2. adjust. As shown in FIG. 1, the operation part of the main shaft 56, the click 59, and the counter 60 are provided closer to the room than the outer sash 4, so that the outer sash 4 can be framed only by removing a balancer cover 61 described later. The balancer 3 can be easily adjusted from the indoor side while being fixed to.

As shown in FIG. 10, the plate 51 is provided with a locking piece 63 having a square hole 62 protruding upward, and as shown in FIG. 7, at the left and right ends of the outer peripheral side member 11 of the upper frame 9. A bracket 64 for hooking the locking piece 63 is attached to the lower surface. The bracket 64 is formed by pressing a metal plate. As shown in FIG. 12 (a), the bracket 64 has a hole 65 into which the locking piece 63 can be inserted from below, and from both left and right sides of the hole 65. Claw pieces 66, 66 are provided projecting inward and can be inserted into the holes 62 of the locking pieces 63, and are also used for the left and right balancers 3, 3.
As shown in FIG. 13A, the balancer 3 is inserted into the upper frame 9 with the upper part tilted to the outer peripheral side, and the locking piece 63 is hooked on the bracket 64 of the upper frame 9 from below. Then, as shown in FIG. 13B, the base member 47 of the balancer 3 comes into contact with the inner peripheral side surface of the outer peripheral side member 22 of the vertical frame 5 to be in a vertical posture, and one lower portion of the base member 47 is moved vertically. Are fixed to the outer peripheral side member 22 with screws 67 from the inner peripheral side. Since the screw 67 is located closer to the room than the frame fixing piece 68 of the vertical frame 5 (see FIG. 2), the distal end of the screw 67 is not exposed to the outside.

As shown in FIGS. 1, 7, and 9, a balancer cover 61 made of resin is attached to the inner peripheral side of the balancer 3, and the balancer cover 61 covers the inside exposed surface of the metal plate 51. The balancer cover 61 is provided substantially flush with the inner peripheral side surface of the inner peripheral member 23 of the vertical frame 5 from the lower end to an intermediate position higher than the drum 50, and the latch 7 of the inner sash 2 is provided on the indoor side thereof. A groove portion 55 through which the claw 46 can pass is provided along the up-down direction so as to be continuous with the guide portion (the concave portion 28) of the vertical frame 5. As shown in FIG. 1, the groove 55 extends from a lower end of the balancer 3 to a position higher than a lower end of the barrel 49. Thereby, as shown in FIG. 5, the fitting can slide the inner shroud 2 at the upper end above the lower end of the drum 50, and in the embodiment, further, can slide the inner shroud above the lower end of the barrel 49. The opening area increases in the vertical direction.
As shown in FIGS. 5 and 7, the balancer cover 61 integrally has a stopper 69 for the inner shoji 2 protruding from the inner peripheral side of the vertical frame 5, and an upper end of the inner shoji 2 on the lower surface of the stopper 69. , The upper limit of the inner sash 2 is defined. The balancer 3 is provided with a ratchet 58, a click 59 and a counter 60 on the inner peripheral side of the plate 51, and a stopper 69 is provided so as to cover these components.

  As shown in FIGS. 7, 8, and 12, the balancer cover 61 has a plurality of locking pieces 70a, 70b, and 70c that are inserted and locked into the inner peripheral member 23 of the vertical frame 5 at the lower end. At the upper part, a claw piece 72a for locking to the vertical frame 71 of the outer sash 4 is provided on the outdoor side, and a claw piece 72b for locking to the angle member 39 of the vertical frame 5 is provided on the indoor side. As shown in FIG. 14, the balancer cover 61 inserts and locks the locking pieces 70a, 70b, and 70c formed at the lower end of the balancer cover 61 into the inner peripheral member 23 of the vertical frame 5 in an oblique state, and then locks the upper part. When it is pushed up to the outer peripheral side and raised vertically, as shown in FIG. 8A, the upper claw pieces 72a and 72b are sandwiched and held between the vertical frame 71 and the vertical frame 5 of the shoji. The upper end of the balancer cover 61 contacts the lower surface of the inner peripheral member 12 of the upper frame 9 as shown in FIG. At the lower end of the balancer cover 61, as shown in FIGS. 7 and 8, there is provided an eye drop prevention portion 73 which engages with the eye plate 35 of the vertical frame 5 to prevent the eye plate 35 from lowering. The balancer cover 61 can be easily removed by inserting a tool such as a flathead screwdriver into a notch 74 (see FIG. 9C) formed on the upper indoor side surface of the stopper 69.

As shown in FIGS. 15 to 17, the latch 7 of the inner shoji 2 includes a base 76 fixed to the upper end of a vertical frame 75, and a latch body 77 slidably held in the inner and outer peripheral directions by the base 76. And a spring 78 for urging the latch body 77 to the outer peripheral side, and an operating member 79 provided on the upper surface of the base portion 76. The latch body 77 has a claw 46 protruding from the base portion 76 on the lower side indoor side of the outer peripheral side surface, and the claw 46 is engaged with the entrance side of the concave portion 28 of the vertical frame 5. The operating member 79 is engaged with the latch main body 77, and when the operating member 77 is moved inward, the claw 46 of the latch main body 77 is immersed in the base portion 76, and the inner sash 2 can be tilted indoors. .
The claw 46 of the latch body 77 is provided at a position lower than the upper end of the inner shoji 2 by a predetermined dimension A (see FIG. 15), and the dimension A is determined by the lower surface of the stopper 69 of the balancer cover 61 and the upper end of the groove 55. Is substantially the same as or larger than the dimension B (see FIG. 7) between them. As a result, even when the inner sash 2 is raised to the limit at which the upper end thereof contacts the stopper 69, the claw 46 of the latch body 77 does not reach the upper end of the groove 55, and the inner sash 2 is raised without difficulty to the limit at which the stopper 69 abuts. be able to. In addition, since the claws 46 of the latch 5 are arranged closer to the room, it is possible to prevent the claws 46 from interfering with the drum 50 of the balancer 3 when the inner sash 2 is raised.

As shown in FIG. 1, the upper frame 36 of the inner shoji 2 is configured by combining a metal profile 80 arranged on the outdoor side and a resin profile 81 arranged on the indoor side. The room side from the center of the frame 36 in the indoor / outdoor direction is constituted by hollow portions 82a, 82b, 82c of the resin-made material 81.
As shown in FIG. 16, the latch body 77 has a rear end portion 83 that is inserted into the upper frame 36 when the claw 46 is immersed in the base portion 76. Therefore, the latch body 77 has a substantially crank shape in plan view. When the claw 46 is immersed in the base portion 76, the rear end portion 83 is inserted outside of the hollow portion 82a of the resin profile 81, which is the most outdoor portion. Therefore, it is not necessary to cut out the hollow portions 82a, 82b, and 82c of the resin-made material 81 in order to mount the latch 7, so that the processing is easy and the hollow portions 82a, 82b, and 82c of the resin-made material 81 can be used. High heat insulation performance is obtained.
Note that the frames (lower frame 84 and vertical frame 75) other than the upper frame 36 of the inner shoji 2 are also formed by combining a metal profile 80 and a resin profile 81 in the same manner as the upper frame 36. Each frame of the shoji 4 is also configured by combining a metal profile 80 and a resin profile 81.

  As described above, in this fitting, the founder size of the upper frame 9 can be reduced by attaching the balancer 3 for suspending the inner sash 2 to the upper inner peripheral side surface of the vertical frame 5, and the balancer 3 The inner sash 2 has a drum 50 that winds up the wire 6 that hangs the sash 2, and the inner sash 2 is guided to a height that is higher than the lower end of the drum 50. The sliding area can be slid to a position higher than the lower end (the embodiment can further slide to a position higher than the lower end of the barrel 49), so that the opening area can be increased. Since the balancer (balancer cover 61) has a groove 55 through which the claw 46 of the latch 7 of the inner shroud 2 can pass from the lower end to an intermediate portion in the vertical direction, the claw 46 of the latch 7 collides with the balancer 3 and the balancer 3 is closed. The movable range of the shoji 2 is not restricted. Further, since the balancer (balancer cover 61) has the stopper 69 of the inner sash 2 at a position higher than the drum 50, it is not necessary to separately install the stopper 69, so that component costs and assembly costs can be reduced, and the balancer can be further reduced. A wide opening area can be ensured regardless of the size of 3.

  In this fitting, the base member 47 of the balancer 3 is made of resin, the drum 50 and the barrel 49 are held by the resin base member 47 and the metal plate 51, and the resin base member 47 is vertically framed. By contacting the inner peripheral side surface of the inner peripheral surface 5, cold air can be prevented from being transmitted from the vertical frame 5 to the balancer 3, so that the heat insulating performance is improved. Since the base member 47 itself is made of resin, there is no need to interpose a heat insulating material such as a resin spacer between the balancer 3 and the vertical frame 5, so that the number of parts can be reduced and the balancer 3 can be mounted. It becomes simple, and the thickness of the balancer 3 can be reduced. Further, since the shaft 90 and the like of the drum 50 can be integrally formed with the base member 47, the thickness of the balancer 3 can be reduced. In the balancer 3, the main components such as the base member 47 and the drum 50 are made of resin, and the periphery of a metal case 92 of the barrel 49 is covered with a side wall 93 of the base member 76. Heat insulation is higher than when heat insulation is provided by interposing a resin spacer or the like only on the mounting surface. Furthermore, since the inside view exposed surface of the metal plate 51 of the balancer 3 is covered with the balancer cover 61 made of resin, the radiation of cool air from the plate 51 into the room can be suppressed. Further improve. By arranging the metal plate 51 on the inner peripheral side, necessary strength can be ensured, and components to which a load such as the ratchet 58 and the click 59 can be arranged on the plate 51.

  In this fitting, the balancer 3 is attached to the upper inner peripheral side surface of the vertical frame 5, and the balancer 3 fits within the found dimensions of the vertical frame 5, and the upper portion is inserted only into the upper frame 9. In addition, the opening area can be increased in both the vertical and horizontal directions. This fitting has a bracket 64 on the lower surface of the upper frame 9, and the balancer 3 has a hook portion (locking piece 63) for hooking on the bracket 64, so that the balancer 3 is inserted only into the upper frame 9 and attached. Easy to do. Since the hook (locking piece 63) of the balancer 3 is provided on the metal plate 51, the load applied to the balancer 3 can be transmitted to the upper frame 9, so that the balancer 3 can be held with only one screw 67. It can be attached to the frame 1 stably. The vertical frame 5 includes an outer peripheral side (outer peripheral member 22) and an inner peripheral side (inner peripheral member 23), and the inner peripheral side (inner peripheral member 23) is provided below the balancer 3. By having the guide portion (recess 28) of the inner sash 2 and the insertion portion 29 of the suspending member (wire 6) that hangs the inner sash 2, there is no need to perform complicated processing on the vertical frame 5 to mount the balancer 3. Manufacturing costs can be reduced. Furthermore, the inner peripheral side portion (the inner peripheral side member 23) is made of resin, and the heat insulating property and the design property are improved because the insertion portion 29 of the hanging member is closed with the resin plate 35.

  In this fitting, since the shaft 90 of the drum 50 of the balancer 3 is oriented in the left-right direction, the balancer 3 can be accommodated in the vertical frame 5, and since the balancer 3 does not need to be accommodated in the upper frame 9, the upper frame Since the apparent size of No. 9 can be reduced, the opening area (vertical direction) can be increased. Since the balancer cover 61 is attached between the upper end of the inner peripheral member 23 of the vertical frame 5 and the upper frame 9, the design is good. The balancer cover 61 can be easily removed from the indoor side, and adjustment and maintenance of the balancer 3 can be easily performed by removing the balancer cover 61.

FIG. 19 shows another embodiment of the bracket 64 and the balancer cover 61 attached to the upper frame 9. The bracket 64 has a left-right difference and has a hanging piece 85 separately from the claw piece 66 for hooking the balancer 3, and the stopper 69 at the upper part of the balancer cover 61 is engaged with the hanging piece 85 from the inner peripheral side. At the same time, the downward impact received by the stopper 69 when the inner sash 2 is fully opened can be received by the lower end of the hanging piece 85.
According to the present embodiment, when attaching the balancer cover 61, the lower end of the balancer cover 61 is placed on the upper end of the inner peripheral member 23 of the vertical frame 5 in an inclined state, and then the balancer cover 61 is erected. The balancer cover 61 can be mounted simply by engaging the vicinity of the upper end of the balancer cover 61 with the hanging piece 85 of the bracket 64, and the balancer cover 61 can be easily attached.
By using the hanging piece 85 of the bracket 64, the impact received by the stopper 69 when the inner sash 2 is opened can be received by the hanging piece 85, and can be reliably received by the upper frame 9 from the hanging piece 85. In addition, since the projection 86 provided at the lower end of the balancer cover 61 is fitted to the mounting portion of the vertical frame 5, the balancer cover 61 is engaged with the upper and lower sides, respectively, and can be stably fixed. .

  The invention is not limited to the embodiments described above. The form of the frame or the shoji can be changed as appropriate. The balancer only needs to be a drum type, and the specific structure is not limited. The balancer does not have to be embedded only in the upper frame, but by inserting the balancer, the opening area (vertical dimension) can be further increased. The balancer may be within the found size of the inner peripheral side member of the vertical frame, and may be concealed by the balancer cover without a step from the inner peripheral side member, or may be concealed by providing a step on the balancer cover even if it slightly protrudes. It may be something. In the latter case, a portion protruding toward the inner peripheral side of the balancer cover can be used as a stopper for the shoji. The present invention can be applied to doors with up / down windows in addition to up / down windows.
