  Note that the pulley 81 (82, 83) can hang a wire W around the pulley 140 so as to pass through m and n as shown in FIG. 12 (a), for example. Further, it is possible to hang from m through the wire W to the pulley 140 and to lead out in the direction of p through the central hole 134a of one shaft portion 134. It is also possible to lead out in the direction of o through the central hole 134a of the shaft portion 134.

  In the present embodiment, each of the pulleys 81, 82, and 83 has an extension piece of the upper rod 11 so that the axis of the shaft portion 134 of the holding member 131 is along the width direction of the window (left and right direction in FIG. 3). The pulleys 81, 82, and 83 are provided on the upper collar 11 and the upper frame 5 by being in contact with and fixed to the indoor side surface of 11 b or the outdoor side surface of the extending piece 5 b of the upper frame 5, respectively.

  In this embodiment, the turning pulley 74 and each of the pulleys 81, 82, and 83 are arranged such that the upper frame 5 of the window frame 1 and the upper arm of the shoji 2 in the state where the shoji 2 is closed as shown in FIGS. 11 is arranged in a space portion formed by.

The wire W wound around the wire take-up drum 50 of the apparatus main body 21 is passed through the hole 2a formed in the right end portion of the extending piece 11b of the upper arm 11 of the shoji 2 and the hole 75a of the case 75, thereby turning the pulley. 74.
Specifically, as shown in FIGS. 5 and 6, a through hole 2a is formed in the right end portion of the extending piece 11b of the upper collar 11 along the front-rear direction (indoor / outdoor direction). A through hole 75a is formed on one side surface of the case 75 so as to communicate with 2a. That is, the case 75 in which the through hole 75 a is formed on one side surface is attached to the shoji 2 so that the through hole 75 a communicates with the through hole 2 a of the shoji 2.
A through hole 71 a through which the wire W is passed is formed at a position corresponding to the through hole 2 a of the shoji 2 in the piece 71 of the mounting member 70.

The wire W hung on the turning pulley 74 is passed through an outer 77 provided on the case 75 and led out from the case 75 to the left in the state shown in FIGS.
The outer 77 has an elongated tube shape, one end of which is fixed to the case 75 and communicates with the hollow portion of the case 75, and the other end extends from the case 75 to the left in FIGS. 3 and 6.

The wires W extending from the outer 77 are sequentially wound around the pulleys attached to the window frame 1 and the shoji 2. In this embodiment, after being hung on the right pulley 82 attached to the shoji 2, it is hung on the pulley 83 attached to the window frame 1, and further hung on the left pulley 81 attached to the shoji 2. The tip of the wire W is fixed to the window frame 1.
Specifically, in the plan view shown in FIG. 3, the wire W extending from the outer 77 is opened from the pulley 82 on the right side of the upper rod 11 from the window frame 1 so that the tension acts in a direction to close the shoji 2. It is further hung on a pulley 83 on the upper frame 5 and a pulley 81 on the left side of the upper rod 11, and its tip is fixed to the window frame 1.

Next, the operation of the window opening / closing device of this embodiment will be described.
In a state in which the wire W is wound around the wire winding drum 50, the shoji 2 closes the opening of the window frame 1 against the urging force of the pair of dampers 15 due to the tension of the wire W.
Here, when the operator pulls the handle 62 of the rope L of the winding release means 58, the short shaft 39 of the left rotating gear 41 moves downward, so that the left rotating gear 41 and the wire winding drum 50 are moved. The engagement with the gear 52a is released. Then, the wire take-up drum 50 is in a free state, the wire W is pulled out by the urging force of the damper 15, and the shoji 2 is gradually opened by the projecting output of the braked rod of the damper 15. At this time, the braking members 55 and 56 of the brake mechanism 53 overcome the pulling force of the tension spring 57, and the braking surfaces 55d and 56d of the braking members 55 and 56 contact the inner peripheral surface 54a of the brake member 54.
For this reason, the unexpected high-speed rotation of the wire winding drum 50 is suppressed, and the shoji is opened without the wire W being wound on the wire winding drum 50.
As shown in FIGS. 1 and 4, when the shoji 2 is opened to a predetermined extent, further rotation of the damper 15 with respect to the bracket B2 (B1) is restricted. Thereby, the opening beyond the predetermined of the shoji 2 is prevented.
Note that the opening angle of the shoji 2 can be appropriately determined in advance according to the size of the shoji, etc., depending on the type of damper, the size of its mounting bracket (bracket), the mounting position of the damper, and the like.

When closing the shoji 2, the operator pulls the ball chain 27 hung on the left side of the case 22 in FIG. 10 (in the direction of the arrow) and rotates the chain wheel 26 counterclockwise in FIG. Along with this, the drive shaft 30 rotates counterclockwise (counterclockwise), and the main transmission gear 35 and the sub transmission gear 36 that mesh with the drive gear 32 rotate in conjunction with each other (see FIG. 8).
The left and right rotation gears 41 and 42 are interlocked with the rotation of the auxiliary transmission gear 36. At this time, the rotation gear 41 rotates before the rotation gear 41 rotates due to the frictional resistance by the spring washers 211 and 221. The link plate 38 rotates in the rotation direction (clockwise) of the auxiliary transmission gear 36.
Then, the left rotating gear 41 meshes with the gear 52a of the wire winding drum 50, and the wire winding drum 50 is interlocked (clockwise). As a result, the wire W is gradually wound and the wire W is pulled by overcoming the biasing force of the damper 15, so that the shoji 2 is gradually closed.
In this embodiment, when the shoji 2 closes the opening of the window frame 1 or when the operation of the ball chain 27 is stopped in the middle, the left claw portion 46a of the clutch member 46 constituting the rotation direction regulating mechanism 45 is Since the reverse rotation preventing function is engaged with the claw teeth 31a of the claw gear 31, the clockwise rotation of the drive gear 32 is restricted. Therefore, the wire take-up drum 50 stops and does not rotate backward, the closed state of the window is maintained, and the shoji 2 does not open even if the operation is stopped halfway. In addition, since the guard 29 that covers the upper portion of the chain wheel 26 is formed integrally with the holder 28, the ball chain 27 can be prevented from being detached from the chain wheel 26 when the ball chain 27 is operated.

Since the apparatus main body 21 is attached to the shoji 2, the window opening / closing operation apparatus of the present embodiment can be attached to the smoke exhaust window in advance when the smoke exhaust window is attached to the building.
That is, before attaching the smoke exhaust window to the opening of the wall of the building, the window opening / closing operation device of this embodiment can be attached to the window in advance at a window manufacturing factory or assembly factory. Thereby, at the construction site of a building, a window opening / closing operation device can be attached only by attaching a window, and the operation is simple.
As described above, the window opening and closing device of this embodiment can be a unit integrated with the window, and it is only necessary to attach the window at the construction site, and there is no need for troublesome wall surface construction. Installation can be completed without waiting. Moreover, since it can be attached to the window in advance at a factory or the like, it is possible to improve the attachment accuracy and to achieve uniform operation and to obtain a stable operation.

  Moreover, in this embodiment, rain water and wind do not enter the room by covering the hole 2a for leading out the wire W formed in the shoji 2 with the case 75. Furthermore, in the present embodiment, the device main body 21, the shoji hole 2a, and the turning pulley 74 are arranged along the front-rear direction (indoor / outdoor direction), and the wire W led out from the device main body 21 is hung around the turning pulley 74. There is no bend in between and the operation is smooth and excellent in durability.

The size of the box 250 may be set so that the box 250 can be fitted to the outdoor side from the extending piece 11b of the upper collar 11 of the shoji 2 up to the center in the front-rear direction.

Next, still another modification of the wire guide member will be described.
23 and 24 are views showing another modification of the wire guide member, FIG. 23 is a longitudinal sectional view, and FIG. 24 is a transverse sectional view thereof.

  The wire guide member 270 of this modification example has basically the same configuration as the wire guide member 245 shown in FIGS. 20 and 21, and the same members are denoted by the same reference numerals, and different parts are mainly described. To do. When using the wire guide member 270 of this modification, the apparatus main body 21 is attached slightly below, and the wire W is led out from the upper part of the apparatus main body 21.

  In the wire guide member 270 of this modification, a pair of rollers 251 and 252 are arranged in the box 250 with the rotation axis arranged vertically. A U-shaped support member 283 that opens to the indoor side for rotatably holding the rotation shafts 251 a and 252 a of the rollers 251 and 252 is provided in the box 250. In this modification, a cover 277 is provided so as to cover the indoor side end of the box 250.

The cover 277 is formed in a U shape that is elongated downward in the front-rear direction (outdoor direction), and the indoor side end portion is bent downward in a gentle arc shape, and the box 250 is placed in the outdoor end portion thereof. Is provided.
A pulley 275 is disposed inside the indoor side end portion of the cover 277 along the rotation shaft 275a along the left-right direction (the width direction of the window). The rotation shaft 275a is an open end piece of the cover 277. Is held rotatably.

  The wire W led out from the apparatus main body 21 is hung on a pulley 275 held by a cover 277, extends to the outdoor side, passes between a pair of rollers 251, 252, and then penetrates the airtight member 257.

Further, the angle 59 is attached to the short shaft 40 of the right rotating gear 42. Thus, in FIG. 10, by pulling the right side of the ball chain 27 downward, the drum 50 rotates counterclockwise, the wire W is wound up, and the shoji is closed.

  Furthermore, the structure of the apparatus main body 21 is also changed as appropriate. In other words, any configuration may be used as long as it has a drum capable of winding and feeding a wire and can regulate the rotation of the drum.

  In the above embodiment, the case where the window opening / closing operation device of the present invention is applied to the inward, outward, and protruding smoke exhaust windows has been described. Is possible. The side-opening smoke exhaust window is one in which the left and right ends of the shoji are rotatably held by the left and right ends of the window frame, and is opened by tilting the shoji from the closed state to the indoor side or the outdoor side. Similarly to the embodiment, the apparatus main body 21 can be attached to a shoji or a window frame.

Moreover, it is good also as a structure which conceals the damper used for an inside-down type or an outside type smoke exhaust window. That is, in a state in which the shoji is closed, the damper may be housed in a space portion formed between the vertical frame of the window frame and the shovel of the shoji.
For example, when the damper is a concealment type in the inversion type smoke exhaust window shown in FIGS. 1 to 6, as shown in FIG. 25, the vertical frames 3 and 4 of the window frame 1 and the vertical rods 9 and 10 of the shoji 2 are used. The damper 15 is disposed in a space formed between the two. The upper end of the cylinder 16 is rotatably attached to a bracket B1 fixed to the vertical piece 9a of the vertical rod 9 and 10 of the shoji 2, and the lower end of the rod 17 is connected to the vertical frames 3 and 4 of the window frame 1. What is necessary is just to attach rotatably to bracket B2 fixed to the vertical pieces 3a and 4a.

Furthermore, in the said Example, although the glass plate was engage | inserted in the shoji of a shoji, you may insert a metal plate etc. instead of a glass plate.
