A reciprocating pulley holder is provided on the sash frame, and a restraining portion is provided on the upper frame of the sash frame to prevent the pulley holder from moving to a moving position in the shoji opening direction when the sash is closed. , a holder to which a shoji side pulley is rotatably attached via a shaft portion whose axial direction is the longitudinal direction of the upper stile is swingably provided, and the shoji side pulley is brought into a projecting state in the shoji closing direction; At the bottom of the upper frame,
A holder to which a frame side pulley is rotatably attached is provided in a swingable manner through a shaft part whose axial direction is the longitudinal direction of the upper frame, and a wire for opening and closing the shoji is stretched across both said pulleys. It is said that

The movement of the pulley holder in the above configuration includes linear reciprocating motion and circular arc reciprocating motion about the axis.

(Example) This invention will be explained below based on the drawings.

1 to 5 are diagrams illustrating an embodiment of this invention, and here, in FIGS. 1 to 4, the left side is assumed to be the outdoor side, and the right side is assumed to be the indoor side.

That is, as shown in FIGS. 1 to 4, the smoke exhaust window 1 consists of an upper frame 2, a lower frame 3, and a pair of vertical frames 5 (one side omitted), and a sash frame A fixed to the building frame. , upper stile 6, lower stile 7 and a pair of vertical stile 8
It is equipped with a shoji B in which glass 9 (shown by a phantom line) is incorporated into a frame made of (one side omitted).

When attaching the shoji B to the sash frame A, a hooking part 3 is attached to the outdoor side of the lower frame 3, the upper end of which has a semicircular cross section, and which protrudes toward the indoor side from the side.
A shoji pivot window frame 3a equipped with a shoji frame 3a is erected, and a semicircular receiving portion 7a formed at the lower end of the lower stile 7 on the outdoor side is engaged with the upper end of the projecting wall 3a. A stopper member 10 suppresses the amount of rotation of the receiving portion 7a with respect to the upper end portion of the receiving portion 3a. At this time, a hooking part 7b is formed at the tip of the receiving part 7a and projects in a direction opposite to the center of the semicircular shape formed by the receiving part 7a. The stopper member 10 includes a guide portion 10a having an arc-shaped inner circumferential surface corresponding to the rotation locus of the hook portion 7b of the receiving portion 7a, and a mounting portion 10b extending substantially horizontally from the guide portion 10a toward the indoor direction. At the upper and lower ends of the guide portion 10a, there are a retaining protrusion 10c and a locking piece 10d that protrude toward the approximate center of the arc formed by the guide portion 10a. Then, the stopper member 10 brings the hooking piece 10d into contact with the lower surface of the hooking portion 3b of the projecting wall 3a,
The tip of the attachment part 10b is fixed to the attachment part 3c formed on the lower frame 3 with a screw 4.

Therefore, the shoji B has the hook part 7 of the receiving part 7a.
It is possible to rotate the shoji B toward the outdoors until it comes into contact with the retaining protrusion 10c, and in this embodiment, the shoji B can be rotated approximately 90 degrees.

Upper stile 6 in shoji B installed as above
A shoji-side pulley 12 is provided on the upper surface of the shoji B via a pulley holder 11 that can reciprocate both indoors and outdoors. As shown in FIG. 5, the pulley holder 11 is made by connecting a pair of plates 11a, 11a at a predetermined interval, the upper ends of which are bent toward indoors. , holding portions 1 are provided at both ends of the base portion 13b in which the screw holes 13a are formed.
3c, 13c facing each other, the lower ends of the plates 11a, 11a and the holding parts 13c, 13c are rotatably connected by a shaft 13d, and a backing fitted into the upper frame 6 is used. Board 1
4 and the bracket 13 is fixed to the upper surface of the upper frame 6 with screws 15. In addition, both plates 11
A roller 16 is installed between the upper ends of the rollers 11a and 11a, and faces a restraining portion to be described later. The shoji-side pulley 12 is rotatably attached to a holder 17 that holds the pulley 12 therebetween. is rotatably mounted. At this time, the axial direction of the pin 18 is the longitudinal direction (horizontal direction) of the upper stile 6.
Note that the upper stile 6 has a rising wall 6a whose outdoor surface extends upward.

The shoji-side pulley 12 that has been installed as described above is in a protruding state in the shoji closing direction (indoor direction) and can freely swing around the pin 18 within the range where it comes into contact with the roller 16 or the upper stile 6. In the case of the example,
Roller 16 and pin 1 are installed so that the roller 16 and pin 1 can be rotated downward from a horizontal position to an angle of 45 degrees or more.
The position of 8th grade is set.

On the other hand, the upper frame 2 of the sash frame A has an L-shaped hanging wall 2a that extends downward toward the indoor end, and
When the upper frame 2 is closed, the lower surface of the upper frame 2 and the hanging wall 2
a, and the upper surface of the upper stile 6 and the rising wall 6a form a space 19 (shown in FIG. 3). A bracket 20 having an L-shaped cross section is fixed to the corner of the lower surface of the upper frame 2 and the hanging wall 2a, and the bracket 20 is connected to a holding part 20a protruding from the lower end of the bracket 20 via a pin 21 as a shaft part. , the holder 23 of the frame side pulley 22 is rotatably attached. On this occasion,
The axial direction of the pin 21 is the longitudinal direction (horizontal direction) of the upper frame 2. The frame-side pulley 22 is rotatable downward from at least a horizontal state to an angle of about 45 degrees.

Further, on the lower surface of the upper frame 2, a restraining member 24 is provided as a restraining portion for restraining the pulley holder 11 to a moving position on the shoji opening direction side (outdoor side) when the shoji B is in the closed state. . This restraining member 24 has a hanging wall-shaped abutment part 24b on a mounting part 24a fixed to the lower surface of the upper frame 2 with a screw 25, and the abutment part 24b is in contact with the roller 16 of the pulley holder 11. It is provided at a position where it can come into contact with 24b.

Here, in this embodiment, one shoji side pulley 1
2, two frame-side pulleys 22 are provided. Each pulley 12, 22 has almost the same diameter, and the two frame-side pulleys 22, 22 are attached to the aforementioned bracket 20 at an interval corresponding to the diameter of the shoji-side pulley 12, and the shoji-side block B is closed. When the shoji side pulley 1 is inserted between both frame side pulleys 22, 22,
The position is such that 2 can be accommodated.

A wire 26 for opening and closing the shoji screen is stretched across both the pulleys 12 and 22. Both end sides of the wire 26 are guided in opposite directions along the upper frame 2 from each frame side pulley 22, and one end side is guided in opposite directions from the frame side pulleys 22 to the sash frame A.
The winding device is fixed to the winding device, etc., or is fixed by being wrapped around the pulley of another adjacent smoke exhaust window, and the other end is connected to a winding device provided at a remote location.

In addition, a tight material 27 is provided on the inner peripheral portion of the sash frame A to press against the indoor surface of the shoji B when it is closed. Furthermore, the shoji B is always pressed toward the outdoors by interposing a telescopic arm (not shown) containing, for example, a spring between the vertical stile 8 and the vertical frame 5 of the sash frame A.

The above-mentioned smoke exhaust window 1 is placed, for example, in the upper part of a building wall, and is used to exhaust smoke in emergencies and ventilate in normal times, and allows the wire 26 to be fed out and wound from a remote location. This opens and closes the shoji B.

The above-mentioned smoke exhaust window 1 is installed by letting out the wire 26
As the wire 26 is opened, various resistances are acting on the wire 26, so a difference arises between the speed at which the wire 26 is fed out and the opening speed of the shoji B, and the shoji B rotates first. As shown in FIG. 2, as the shoji B rotates, the pulley holder 11 with the roller 16 in contact with the restraining member 24 rotates clockwise in the figure relative to the shaft 13d. Rotate. As a result, the shoji side pulley 12 becomes in a state (the state shown in FIG. 1) in which it protrudes more than the indoor surface of the shoji B. Therefore,
As mentioned earlier, in this embodiment, the shoji B can be rotated 90 degrees, and each pulley 12, 22 can be rotated downward.
Since it can be rotated by 45 degrees, even when the shoji B is in its maximum open state (the state shown in Figure 4), both pulleys 1
2 and 22 are maintained on the same plane via a wire 26. At this time, in the smoke exhaust window 1, the shoji side pulley 12 largely protrudes from the indoor surface of the shoji B and can be rotated downward to an angle of 45 degrees or more, so that the pulley 12 and the wire 26 are attached to the upper stile. 6
There is no fear that the upper stile 6 will be damaged by contact with the pulley 12 or the like.

Next, when the wire 26 is wound up and the shoji B is rotated in the closing direction, the roller 16 first comes into contact with the contact portion 24b of the restraining member 24, so as the shoji B continues to rotate, the pulley The holder 11 is relatively
It rotates toward the outdoors around 3d (the state shown in Fig. 2). When the shoji B reaches the closed state (the state shown in FIG. 3), the rotation of the pulley holder 11 causes the position of the pin 18 to move toward the outdoors relative to the shaft 13d, and as a result, the shoji side pulley 12 is pulled toward the center of the upper surface of the upper stile 6. At this time, the smoke exhaust window 1 can maintain a good appearance because the pulleys 12, 22, brackets 13, 20, etc. are accommodated in the space 19 formed between the upper frame 2 and the upper stile 6. can.

As explained in the above embodiment, if the diameters of both pulleys 12 and 22 are made almost the same and the interval between the two frame side pulleys 22 and 22 is made to correspond to the shoji side pulley 12, each pulley Wire 2 to 12, 22
The winding state of the wire 6 can be maintained constant, and a decrease in the durability of the wire 26 can be further prevented.
In other words, in the case of the above configuration, no matter what posture the shoji B is in, the wire 26 contacts approximately half the circumference of the shoji side pulley 12, and the wire 26 also contacts approximately one quarter of the circumference of the frame side pulley 22. Furthermore, the wires 26 extending from the shoji side pulley 12 to the two frame side pulleys 22 are always kept substantially parallel.

FIGS. 6 to 8 are diagrams illustrating other embodiments of this invention. In addition, similarly to the previous embodiment, the left side of the figure will be described as the outdoor side and the right side will be described as the indoor side, and the same parts will be denoted by the same reference numerals and detailed explanation will be omitted.

That is, this embodiment shows a configuration including a pulley holder 31 that linearly reciprocates in the indoor and outdoor directions of the shoji B.

The pulley holder 31 has holding portions 31b, 31b opposed to each other at both ends of a plate-shaped base 31a, and engagement protrusions 31c that protrude horizontally and in parallel from both sides of the base 31a. and
The holder 17 of the shoji-side pulley 12 is rotatably attached to a pin 18 serving as a shaft extending between the upper ends of both the holding parts 31b, 31b.

Further, the reference numeral 32 in the figure is a guide body of the pulley holder 31, and this guide body 32 is attached to the upper stile 6.
Opposite guide parts 32b, 32b are formed by bending at both ends of the flat part 32a fixed to the upper surface, and elongated guide holes 32c, 32 are formed in the guide parts 32b, 32b, extending linearly in the expected direction of the shoji B.
c is formed. And each guide hole 32
The engagement protrusions 31c on both sides of the pulley holder 31 are slidably engaged with the engagement protrusions 31c on both sides of the pulley holder 31, respectively.

Further, in a place adjacent to the guide body 32, a mounting tool 3 is fixed to the upper surface of the upper stile 6 with a screw 33.
4, an arm 36 is rotatably attached via a shaft 35. This arm 36 rotates in the indoor and outdoor directions of the shoji B, and its tip is connected to the contact portion 2 of the restraining member 24.
It has enough length to reach 4b. Further, the arm 36 has a long hole 36a in the intermediate portion, which is long in the longitudinal direction of the arm 36.
6a is engaged with an end portion of the pin 18 that protrudes from one holding portion 31b of the pulley holder 31. Therefore, the sliding pulley holder 31 and the rotating arm 36 are interlocked by the engagement between the pin 18 and the elongated hole 36a.

In the smoke exhaust window having the above configuration, when the shoji B is closed, the pulley holder 31 is restrained to a moving position in the direction of opening the shoji (outdoor side) by the contact between the restraining member 24 and the arm 36. (the state shown in Figures 6 and 7). At this time, the shoji side pulley 12 is pulled toward the center of the upper stile 6 along with the pulley holder 31. Next, when the wire 26 is fed out and the shoji B is rotated toward the outdoors, there is a difference between the feeding speed and the opening speed of the shoji B due to various resistances acting on the wire 26. Since the shoji side rotates first, as the shoji B rotates, the pulley holder 11 moves relatively toward the indoor side with the rotation of the arm 36, and as a result, the shoji side pulley 12 moves toward the indoor side. It will be in a state where it largely protrudes from the indoor surface of B (the state shown in FIG. 8).

Even with such a configuration, the same effects as in the previous embodiment can be obtained. In addition, the pulley holder 31
Although it is possible to provide a portion directly in contact with the restraining member 24, when the pulley holder 31 is moved indirectly via the arm 36 as in the above embodiment, the arm 36 serves as a lever,
The operation of the pulley holder 31 can be made even smoother. In addition, as shown in FIGS. 6 and 7, when the protrusion 6b is formed on the indoor side edge of the upper stile 6, the protrusion 6b is formed only in the area corresponding to the guide body 32. (particularly shown in Figure 7) to remove the shoji side pulley 1 when the shoji is fully opened.
Make sure that 2 does not interfere.

FIG. 9 is a diagram illustrating still another embodiment of this invention, in which the upper side of the figure is the outdoor side and the lower side is the indoor side.

That is, in this embodiment, a pulley holder 31 and a guide body 32 similar to those in the previous embodiment are provided, and the axial direction of the shoji B is attached to a fixture 41 fixed near one side of the guide body 32 with a screw 40. An arm 43 is rotatably attached via a shaft 42 pointing upward. The arm 43 is located above the shoji-side pulley 12, with its tip protruding to the opposite side of the guide body 32, and has a long hole 43a extending in the longitudinal direction of the arm 43 in its center. have. An engagement pin 44, which is provided upright at approximately the center of the base portion 31a of the pulley holder 31, is engaged with the elongated hole 43a.

In the above-mentioned smoke exhaust window, when the shoji B is in the closed state, the pulley holder 31 is moved in the shoji opening direction due to the abutment between the tip of the arm 43 and the restraining member 24 (shown by imaginary lines) of the sash frame. The shoji side pulley 12 is restrained to the side (outdoor side) movement position, and the shoji side pulley 12 is pulled toward the center of the upper surface of the upper stile 6. Furthermore, when the shoji B is opened, the pulley holder 31 moves toward the indoor side of the shoji B as the arm 43 rotates, causing the shoji side pulley 12 to protrude greatly from the indoor surface of the shoji B (imaginary in the figure). line condition).

As described above, the same effects as in the previous embodiments can be obtained even by using the arm 43 that rotates substantially parallel to the upper surface of the upper stile 6.

In addition, the mounting structure and rotation direction of the shoji to the sash frame, the mounting structure and number of each pulley,
Alternatively, the structure of the pulley holder is not limited to the above-mentioned embodiments, and the restraining part may also be provided integrally with the upper frame. In addition, the position of the shaft of the shoji side pulley depends on the movable range of the pulley holder, the diameter of the pulley,
It can be set as appropriate depending on the expected dimensions of the upper stile or the rotation angle of the shoji.

[Effects of the invention] As explained above, according to the smoke evacuation window of this invention, the position and posture of the shoji side pulley are changed when the shoji is opened and when the shoji is closed in accordance with the movement of the pulley holder, The wire can be guided smoothly using only each pulley, and the load during opening/closing operations can be reduced by eliminating the conventionally used guide member, and a decrease in the durability of the wire can be prevented. In addition, since the shoji side pulleys that protrude largely from the shoji are pulled into the shoji side when the shoji is closed, the space created between the upper frame and the upper stile for storing the pulleys can be minimized, and the design is improved. This has effects such as being advantageous in terms of performance and design.
