  Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1-6 has shown one Embodiment of the fitting of this invention. This joinery is a raising / lowering window installed in a window opening of a house, and as shown in FIGS. 1 to 4, the frame 1 is fixed to the housing opening, and is arranged on the upper side of the outdoor side in the frame 1. The external shoji 4, the inner shoji 2 disposed on the lower side of the indoor side in the frame 1, and the left and right balancers 3 and 3 installed in the frame 1 are provided. The external shoji 4 is a fixed shoji 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 impeller 2 is suspended by wires 6 and 6 extending from the balancers 3 and 3, and can slide up and down with a light force and can be stopped at an arbitrary height position. . In addition, the inner shoji 2 has latches 7 and 7 that engage with the vertical frames 5 and 5 on both the left and right sides of the upper part, and by releasing the latches 7 and 7, as shown in FIG. This makes it easier to clean the inner shoji 2. The side part of the inner shoma 2 and the vertical frames 5 and 5 are connected by the arms 8 and 8, and the arm 8 and 8 regulate the tilt angle of the inner shunt 2.

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

  As shown in FIG. 20, the inner circumferential side member 12 of the upper frame 9 can also form 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, a hole for allowing the upper portion of the balancer 3 to be inserted can be formed, and an L-shaped notch as shown in FIG. Since 21 becomes unnecessary, processing cost can be suppressed. Moreover, since the inner peripheral side member 12 can be removed with the angle part 16 being attached to the frame 15, the maintainability is improved.

As shown in FIG. 2, the vertical frame 5 includes an outer peripheral side member 22, an inner peripheral side member 23, and an angle member 39. The outer peripheral member 22 is made of an extruded shape of aluminum alloy, and the inner peripheral member 23 and the angle member 39 are made of an extruded shape of synthetic resin.
The outer peripheral member 22 has a finding wall 24 on the outdoor side, and the finding wall 24 protrudes to the innermost peripheral side in the vertical frame 5. The tight material 25 provided between the vertical frames 5 and 5 and provided on the outer peripheral portion of the outdoor side surface of the outer screen 4 is in contact with the indoor side of the front end portion of the finding wall 24. As described above, the external shoji 4 can be installed straight from the indoor side with the left and right arms, so that it has been conventionally necessary to install the external shoji 4 between the vertical frames 5 and 5 in the left and right direction. Since the transfer space is not required, the size of the vertical frame 5 can be reduced, and as a result, the lighting area and the opening area are increased 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 indoor side of the hollow portion 26 of the outer peripheral member 22 from the inner peripheral side. As shown in FIGS. 1 and 9, the inner peripheral member 23 is provided below the balancer 3. That is, the upper portion of the inner peripheral side member 23 is shorter than the outer peripheral side member 22 and is cut into a flat shape to secure a mounting space 27 for the balancer 3 between the upper end of the inner peripheral side member 23 and the lower surface of the upper frame 9. Yes.
As shown in FIG. 2, the inner peripheral member 23 has a concave portion 28 that is recessed toward the outer peripheral side on the indoor side. The bottom portion of the recess 28 serves as an insertion portion 29 for the wire 6 that suspends the inner shoji 2. Inwardly protruding portions 30a and 30b are provided on the inner and outer walls of the wire insertion portion 29, respectively, and projecting on the outer peripheral side at the lower portion of the inner shoji 2 as shown in FIG. The rod rod 31 is guided between the inward projections 30a and 30b. The lower end of the wire 6 is locked to the rod bar 31. The outdoor side of the recess 28 is partitioned into a plurality of hollow portions 32a, 32b, 32c, and 32d.
As shown in FIG. 2, a hook-shaped locking piece 33 is formed on the inner peripheral side of the inward protruding portion 30 a on the outdoor side, and the outdoor side where the indoor side opens on the inner peripheral side of the locking piece 33. A guide groove 34a is provided. A resin eye plate 35 is attached between the locking piece 33 and the inward protruding portion 30b on the indoor side. As shown in FIG. 6, the eye plate 35 is provided from the bottom of the balancer 3 to a height position where it overlaps with the upper eyelet 36 of the inner shroud 2, and the wire insertion portion 29 is hidden behind the eye plate 35 and is invisible. . As shown in FIG. 18, the eye plate 35 is engaged with the engaging portion 37 formed on the outdoor side end portion with the engaging piece 33 of the vertical frame 5, and rotates to the outer peripheral side using the engaging 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 inward protrusion 30b of the vertical frame 5. When removing the eye plate 35, as shown in FIG. 6, it is only necessary to insert a finger into the lower end of the eye plate 35 and pull it toward the inner peripheral side in a state in which the inner limb 2 is turned over.

  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 and 40b formed in the outer peripheral member 22 and the inner peripheral member 23 by locking the locking pieces 41a and 41b from the inner peripheral side. The angle member 39 is made of a synthetic resin extruded shape, and has an angle portion 42 screwed to the frame 15 and a find portion 43 that extends to the inner peripheral side along the indoor side wall of the inner peripheral member 23. doing. The finding portion 43 is formed in a hollow shape. The end portion on the inner peripheral side of the locating portion 43 has an indoor guide groove 34b opened on the outdoor side. The indoor guide groove 34b is provided facing the outdoor guide groove 34a formed in 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 regulating the inward tilt angle of the inner shroud 2 is connected is slidably guided in the vertical direction. Further, the inner peripheral side end 45 of the indoor guide groove 34b is a sliding portion of the claw 46 of the latch 7 attached to the upper part of the inner shroud 2 as shown in FIG. 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 can be removed.

  Thus, by dividing the vertical frame 5 into the outer peripheral side member 22 and the inner peripheral side member 23, the upper inner periphery of the vertical frame 5 can be obtained simply by cutting the upper part of the inner peripheral side member 23 flat. The mounting space 27 for the balancer 3 can be easily secured on the side surface. A concave portion 28 that is recessed toward the outer peripheral side is formed on the inner side of the inner peripheral side member 23, the wire insertion portion 29 extends from the bottom side of the concave portion 28 to the inlet side, and a guide portion (inward facing) of the lower part (rod rod 31) of the inner limb 2. The protrusions 30a and 30b), the guide portions of the arm slider 44 (guide grooves 34a and 34b), and the guide portions (the inner peripheral side end portion 45 of the angle member 39) of the upper portion (latch 7) of the inner shoji 2 are formed in order. Thus, a highly functional guide portion can be configured while the size of the vertical frame 5 is kept compact. The angle member 39 is formed separately from the inner peripheral side member 23, the angle member 39 is extended to the upper frame, and the inner peripheral side end 45 of the angle member 39 is used as a guide portion of the upper part of the inner sward 2 (latch 7). 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 top beyond the lower end of the balancer 3. By making the inner peripheral member 23 and the angle member 39 made of resin and further providing the hollow portions 32a, 32b, 32c, and 32d therein, high heat insulation performance can be obtained. Furthermore, the resin eye plate 35 is attached to the concave portion 28 of the inner peripheral side member 23 to conceal the wire insertion portion 29, whereby the heat insulation performance is further improved and the design property is improved. Since the eyeplate 35, the inner peripheral member 23, and the angle member 39 can be removed, the maintainability is good.

  The balancer 3 is attached to the upper inner peripheral side surface of the vertical frame 5 as shown in FIGS. 7 and 9, and more specifically, between the upper end of the inner peripheral side member 23 of the vertical frame 5 and the upper frame 9. The outer frame 22 is disposed in the space 27 between the outdoor finding wall 24 and the indoor finding part 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 is substantially accommodated on the outer peripheral side from the inner peripheral edge of the indoor side finding portion 43 of the vertical frame 5, that is, within the indoor dimension of the vertical frame 5. When viewed from the indoor side, the balancer 3 is hidden behind the locating portion 43 of the angle member 39 and cannot be seen. Strictly speaking, the tip of the main shaft 56 and the parts such as the ratchet 58 and the click 59 provided on the upper part of the balancer 3 protrude slightly toward the inner peripheral side from the locating portion 43 of the angle member 39. Covered with a stopper 69 of the cover 61 and hidden. Further, the balancer 3 is entirely within the outside dimension of the vertical frame 5 (the outside dimension of the outside wall 24). Further, 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, and the balancer 3 is as much as it is inserted. The lower end position of 3 is high.

As shown in FIGS. 7, 10, and 11, the balancer 3 has a base member 47 formed of a synthetic resin on the outer peripheral side, and a drum 50 that winds the barrel 6 and the wire 6 around the spring spring 48 around the base member 47. Are supported with the respective shafts arranged vertically in the left-right direction, 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. The outer diameters of the barrel 49 and the drum 50 are substantially the same. A barrel gear 52 is provided on the outer circumferential side of the barrel 49, and a drum gear 53 is provided on the outer circumferential 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 rotational torque stored in the mainspring 48 is transmitted to the drum 50 through the linkage gear 54. Thus, by engaging the linkage gear 54 between the barrel gear 52 and the drum gear 53, 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, and the base member 47 A prospective direction dimension can be made small to the outer diameter of the barrel 49 and the drum 50. In other words, the diameter of the barrel 49 and the drum 50 can be made as large as possible with respect to the expected size of the vertical frame 5, thereby providing the balancer 3 capable of handling a large load. The three gears 52, 53, 54 are arranged in a straight line on the vertical line, and the pitch circle diameters of the three gears 52, 53, 54 are the same. Thereby, the torque borne by each gear 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 is reduced toward the inner peripheral side, and a claw 46 of the latch 7 of the inner shingles 2 described later passes through a space 95 (see FIG. 12) formed by reducing the diameter. The groove part 55 which can be formed 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 portion 89. Further, as shown in FIG. 11, the base member 47 is provided with a side wall 93 so as to cover the periphery of the case 92 of the metal barrel 49.

  A metal main shaft 56 is provided on the upper portion of the plate 51 so as to engage with a shaft 57 of the barrel 49, and a ratchet 58 is provided on the main shaft 56. A click 59 is placed 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 mainspring 48 is wound to increase the torque, and when the click 58 is moved to release the meshing with the ratchet 58, the mainspring 48 returns and the torque decreases. To do. Further, a counter 60 that moves in conjunction with the main shaft 56 is provided on the plate 51, and the main shaft 56 is tightened / returned using the counter 60 as a guide so that the torque is balanced with the weight of the inner impeller 2. adjust. As shown in FIG. 1, the operation unit of the main shaft 56, the click 59, and the counter 60 are provided on the indoor side of the outer panel 4, so that the outer panel 4 can be attached to the frame 1 only by removing the 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 projecting upward. As shown in FIG. 7, the left and right end portions of the outer peripheral side member 11 of the upper frame 9 are provided. 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. 12A, the bracket 64 can be inserted into the locking piece 63 from below and from both the left and right sides of the punching hole 65. Claw pieces 66 and 66 that protrude toward the inner side and can be inserted into the holes 62 of the locking piece 63 are used for the left and right balancers 3 and 3.
As shown in FIG. 13A, the balancer 3 is inserted into the upper frame 9 with the upper portion inclined 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 placed in the vertical frame 5. The outer peripheral side member 22 is fixed with screws 67 from the inner peripheral side. Since the screw 67 is located on the indoor side of the frame fixing piece 68 (see FIG. 2) of the vertical frame 5, the tip end side of the screw 67 is not exposed to the outside.

As shown in FIGS. 1, 7, and 9, a resin balancer cover 61 is attached to the inner peripheral side of the balancer 3, and the balancer cover 61 covers the exposed interior surface of the metal plate 51. The balancer cover 61 is provided so as to be substantially flush with the inner peripheral side surface of the inner peripheral side member 23 of the vertical frame 5 from the lower end to an intermediate position higher than the drum 50. A groove portion 55 through which the claw 46 can pass is provided along the vertical direction so as to be continuous with the guide portion (concave portion 28) of the vertical frame 5. As shown in FIG. 1, the groove portion 55 is provided from the lower end of the balancer 3 to a position higher than the lower end of the barrel 49. Thus, as shown in FIG. 5, the present joinery can slide the inner shoji 2 up to the upper end of the drum 50 above the lower end of the drum 50, and the embodiment can further slide up to the lower end of the barrel 49. The opening area is increased in the vertical direction.
As shown in FIGS. 5 and 7, the balancer cover 61 is integrally provided with a stopper 69 of the inner impingement 2 so as to protrude toward the inner peripheral side of the vertical frame 5. Are in contact with each other, so that the upper limit of the inner shoji 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, but 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 70 a, 70 b, and 70 c that are inserted and locked to the inner peripheral side member 23 of the vertical frame 5 at the lower end portion. A claw piece 72a that engages with the vertical rod 71 of the outer panel 4 is provided on the outer side of the upper part, and a claw piece 72b that engages with the angle member 39 of the vertical frame 5 is provided on the indoor side. As shown in FIG. 14, the balancer cover 61 is inserted into and slanted with the locking pieces 70 a, 70 b, 70 c formed at the lower end portion in an inclined state on the inner peripheral side member 23 of the vertical frame 5, and When pushed up to the outer peripheral side and vertically raised, the upper claw pieces 72a and 72b are held between the vertical rod 71 and the vertical frame 5 of the shoji 4 as shown in FIG. The upper end of the balancer cover 61 is in contact with the lower surface of the inner peripheral side member 12 of the upper frame 9 as shown in FIG. As shown in FIGS. 7 and 8, a lower end portion of the balancer cover 61 has an eye plate lowering prevention portion 73 that engages with the eye plate 35 of the vertical frame 5 to prevent the eye plate 35 from being lowered. 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 side of the upper chamber of the stopper 69.

As shown in FIGS. 15 to 17, the latch 7 of the inner shoji 2 includes a base portion 76 fixed to the upper end portion of the vertical rod 75, and a latch main body 77 slidably held by the base portion 76 in the inner and outer peripheral directions. A spring 78 that urges the latch body 77 toward the outer peripheral side, and an operation 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 chamber side on the outer peripheral side surface, and the claw 46 is engaged with the inlet side of the recess 28 of the vertical frame 5. The operation member 79 is engaged with the latch main body 77. When the operation member 77 is moved to the inner peripheral side, the claw 46 of the latch main body 77 is immersed in the base portion 76, and the inner shoji 2 can be brought down indoors. .
The claw 46 of the latch main body 77 is provided at a position that is lowered from the upper end of the inner impeller 2 by a predetermined dimension A (see FIG. 15). The dimension A is 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). As a result, even when the inner edge 2 is raised to the limit where the upper end of the inner cover 2 comes into contact with the stopper 69, the pawl 46 of the latch body 77 does not reach the upper end of the groove 55, and the inner edge 2 is raised without difficulty to the upper limit where the inner edge 2 comes into contact with the stopper 69. be able to. In addition, by arranging the claw 46 of the latch 5 closer to the room, it is possible to avoid the claw 46 from interfering with the drum 50 of the balancer 3 when the inner shroud 2 is raised.

As shown in FIG. 1, the upper arm 36 of the inner shoji 2 is configured by combining a metal shape member 80 disposed on the outdoor side and a resin shape member 81 disposed on the indoor side. The interior side of the tub 36 from the center in the indoor / outdoor direction is constituted by hollow portions 82a, 82b, and 82c of the resin-made material 81.
As shown in FIG. 16, the latch main body 77 has a rear end portion 83 that is inserted into the upper collar 36 when the claw 46 is immersed in the base portion 76, and the rear end portion 83 is the claw 46. Therefore, the latch body 77 has a substantially crank shape in plan view. Then, when the claw 46 is immersed in the base portion 76, the rear end portion 83 is inserted into the outdoor side of the outermost hollow portion 82 a of the resin shaped member 81. Therefore, since it is not necessary to cut out the hollow portions 82a, 82b, and 82c of the resin shaped member 81 in order to attach the latch 7, the processing is easy and the hollow portions 82a, 82b, and 82c of the resin shaped member 81 are used. High heat insulation performance is obtained.
Note that the heels (the lower heel 84 and the longitudinal ridge 75) other than the upper heel 36 of the inner shoji 2 are also configured by combining the metal shape member 80 and the resin shape material 81 in the same manner as the upper heel 36. Each saddle of the external shoji 4 is also configured by combining a metal shape member 80 and a resin shape member 81.

  As described above, this fitting can attach the balancer 3 that suspends the inner impeller 2 to the upper inner peripheral surface of the vertical frame 5, thereby reducing the size of the upper frame 9. The drum 50 has a drum 50 that winds up the wire 6 that suspends the shoji 2, and the inner shoji 2 is guided to a height at which the upper end is higher than the lower end of the drum 50. Since it can slide 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), the opening area can be increased. Since the balancer (balancer cover 61) has a groove portion 55 through which the claw 46 of the latch 7 of the inner shoji 2 can pass from the lower end to the middle portion in the vertical direction, the claw 46 of the latch 7 collides with the balancer 3 to The movable range of the shoji 2 is not restricted. Furthermore, since the balancer (balancer cover 61) has the stopper 69 of the inner shuffler 2 at a position higher than the drum 50, it is not necessary to separately install the stopper 69, so that the parts cost and assembly cost can be reduced, and the balancer can be reduced. A wide opening area can be secured regardless of the size of 3.

  In this joinery, 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. 5 Since it can be made to contact | abut to the inner peripheral side surface, it can prevent that cool air is transmitted to the balancer 3 from the vertical frame 5, Therefore Thermal insulation performance improves. 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 the number of parts can be reduced and the balancer 3 can be attached. The balancer 3 can be made thinner. Further, since the shaft 90 such as the drum 50 can be integrally formed with the base member 47, the thickness of the balancer 3 can also be reduced. In the balancer 3, the main parts such as the base member 47 and the drum 50 are made of resin, and the metal case 92 of the barrel 49 is covered with the side wall 93 of the base member 76. Thermal insulation is higher than the case where insulation is made by interposing a resin spacer only on the mounting surface. Furthermore, since the inside exposed surface of the metal plate 51 of the balancer 3 is covered with the resin balancer cover 61, it is possible to suppress the cool air from being radiated into the room from the plate 51. Further improve. By arranging the metal plate 51 on the inner peripheral side, it is possible to ensure the required strength, and it is possible to arrange components such as the ratchet 58 and the click 59 that are loaded on the plate 51.

  In the present fitting, the balancer 3 is attached to the upper inner peripheral side surface of the vertical frame 5, the balancer 3 is within the size of the vertical frame 5, and the upper part is inserted only into the upper frame 9. The opening area can be increased in both the vertical and horizontal directions. This joinery has a bracket 64 on the lower surface of the upper frame 9, and the balancer 3 has a hooking portion (locking piece 63) for hooking the bracket 64, so that the balancer 3 is attached only to the upper frame 9 and attached. Easy to do. Since the hooking portion (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. It can be attached to the frame 1 stably. The vertical frame 5 is composed of an outer peripheral side portion (outer peripheral side member 22) and an inner peripheral side portion (inner peripheral side member 23), and the inner peripheral side portion (inner peripheral side member 23) is provided below the balancer 3. By having the insertion part 29 of the suspension member (wire 6) that suspends the guide part (concave part 28) of the inner impingement 2 and the inner imperial element 2, there is no need to perform complicated processing on the vertical frame 5 in order to attach the balancer 3. Manufacturing cost can be reduced. Further, the inner peripheral side portion (inner peripheral side member 23) is made of resin, and the insertion portion 29 of the suspension member is closed by the resin eye plate 35, whereby the heat insulation and the design are improved.

  Since the shaft 90 of the drum 50 of the balancer 3 faces in the left-right direction, the present fitting can accommodate the balancer 3 in the vertical frame 5 and does not need to accommodate the balancer 3 in the upper frame 9. Since the size of 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 the balancer 3 can be easily adjusted and maintained 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 and right handedness and has a hanging piece 85 in addition to the claw piece 66 for hooking the balancer 3, and engages the stopper 69 on the balancer cover 61 with the hanging piece 85 from the inner peripheral side. In addition, the upward impact received by the stopper 69 when the inner shroud 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 balancer cover 61 is placed on the upper end of the inner peripheral side member 23 of the vertical frame 5 in a tilted state, and then the balancer cover 61 is raised. The balancer cover 61 can be attached 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.
The hanging piece 85 of the bracket 64 can be used to cause the hanging piece 85 to receive the impact received by the stopper 69 when the inner shroud 2 is opened, and to be reliably received by the upper frame 9 from the hanging piece 85. In addition, since the protrusion 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 in the vertical direction, and can be stably fixed. .

  The present invention is not limited to the embodiments described above. The form of the frame and the shoji can be changed as appropriate. The shape of the resin base member of the balancer and the metal plate can be changed as appropriate. Further, the balancer may be one in which the barrel and the drum are arranged on the same axis. The balancer does not have to be inserted only in the upper frame. The present invention can be applied to a door with a raising / lowering window in addition to the raising / lowering window.
