[0005]

When connecting the tip of the wire to the wire winding drum, the desired position of the wire is sandwiched between the drum member and the wire stopper, and the wire stopper is fastened to the drum member. As a result, the tip of the wire is sandwiched between the drum member and the wire stopper, and is immovably connected to the wire winding drum. If you want to adjust the length of the wire after it has been connected to the wire take-up drum, loosen the wire fasteners to make the wire moveable. After that, the wire is moved to a desired position, and the wire stopper is clamped to the drum member so as to sandwich the wire as described above. As a result, the tip of the wire is immovably connected to the wire winding drum.
In this way, the wire can be connected to the wire winding drum simply by sandwiching the wire between the wire stopper and the drum member, so that the work of connecting the wire to the wire winding drum is easy. Also, since the wire is only sandwiched between the wire stopper and the drum member, adjusting the length of the wire from the weight bar to the wire take-up drum after being connected to the wire take-up drum is not possible. Since the tightening of the metal fitting can be loosened, the wire can be moved, and the wire fixing metal fitting can be tightened, the work of adjusting the length of the wire is easy. Also, in the case where the wire stopper is provided with an insertion hole for inserting the wire, the end of the wire is inserted from one side of the wire stopper into one of the insertion holes and led out to the other side of the wire stopper. ,
Then, the wire stopper is inserted from the other surface side into the other insertion hole and led out to the one surface side of the wire stopper. At this time, the length of the tip of the wire drawn out from the insertion hole is adjusted appropriately. Then, the wire stopper is fastened to the drum member. As a result, the wire is sandwiched between the wire stopper and the drum member, and thus is immovably connected to the wire winding drum. After connecting the wire to the wire winding drum, if it is desired to adjust the length of the wire, loosen the tightening of the wire stopper to make the wire movable. After that, the length of the tip of the wire led out from the insertion hole is adjusted, and the wire stopper is fastened to the drum member so as to sandwich the wire as described above. Thereby, the wire is immovably connected to the wire winding drum. In this way, the wire can be connected to the wire winding drum simply by sandwiching the wire between the wire stopper and the drum member, so that the work of connecting the wire to the wire winding drum is easy. Also, since the wire is only sandwiched between the wire stopper and the drum member, adjusting the wire length from the weight bar to the wire take-up drum after connecting it to the wire take-up drum is not possible. Since it is possible to loosen the tightening of the wire, move the wire, and tighten the wire stopper, it is easy to adjust the length of the wire.

When unwound, the wires 64 and 66 are mounted in such positions as to form a “c” shape with the connecting sides of the wire snaps 60 and 62 becoming narrower. An intermediate pipe 68 is arranged between the intermediate pipe brackets 17. The intermediate pipe 68 is rotatably supported on the U-shaped plate 18 by a shaft portion 70 projecting axially from both ends thereof. The intermediate pipe 68 supports a substantially intermediate position in the longitudinal direction of the screen 54 when the screen 54 is closed,
The screen 54 is prevented from hanging downward in FIG.

Next, a method of connecting the wires 64 and 66 to the wire winding drums 34 and 35 will be described. Since the wire winding drum 34 and the wire winding drum 35 have the same structure as described above, the description of the wire winding drum 35 side is omitted. First, as shown in FIG. 3, the end portion of the wire 64 is inserted into the insertion hole 46 from the front side (the surface side appearing in FIG. 3) of the wire fastening member 44, and the back side of the wire fastening member 44 (see FIG. It is led to the surface side which does not appear in 3). Then, the end portion of the wire 64 led out to the back side of the wire stopper 44 is attached to the wire stopper 44.
Insert it into the insertion hole 48 from the back side of the wire stopper 4
4 to the front side. At this time, the length of the wire 64 from the weight bar 56 to the wire winding drum 35 can be adjusted by adjusting the size of the wire 64 drawn out from the insertion hole 48 to the front side of the wire stopper 44. Next, the screw holes 50 and 5 of the wire stopper 44
The wire stopper 44 is fixed to the drum member 37 by aligning the positions of the screw holes 40 and 42 of the drum member 37 and screwing the screws 38 and 39 into them.
As a result, as shown in FIG. 4, the wire 64 is pinched between the drum member 37 and the wire stopper 44 and its movement is restricted, so that the wire 64 is immovably connected to the wire winding drum 34. It After connecting the wire 64 to the wire winding drum 34, if it is desired to further adjust the length of the wire 64, loosen the screws 38 and 39 slightly, and
After the wire 4 is moved and the wire 64 is moved, the screws 38 and 39 are screwed in the same manner as described above to fix the wire stopper 44 to the drum member 37. Further, the end portion of the wire 64 protruding outside from the insertion hole 48 of the wire stopper 44 may be cut at a desired position.
This allows the weight bar 56 to move from the wire winding drum 3
The length of the wires 64 and 66 up to 5 can be easily adjusted.

Next, the operation of the above embodiment will be described. To close the screen 54, turn on the "close" switch on the controller. As a result, the first operator 24 is maintained in the weak braking state (a state in which there is some resistance to rotation), the second operator operates, and the second take-up pipe 28 causes the wires 64 and 66 to move.
Rotate in the winding direction (clockwise in FIG. 1). For this reason,
As the wires 64 and 66 are wound on the wire winding drums 34 and 35, respectively, the screen 54 is unwound from the first winding pipe 20. Therefore, the weight bar 56 moves in the direction of the second take-up pipe 28 with the rollers 58 of the weight bar 56 being guided by the guide grooves 13 of the guide rails 10 and 12. The screen 54 is completely unwound from the first winding pipe 20, and the wires 64 and 66 are all wound around the wire winding drums 34 and 35, so that the rollers 58 of the weight bar 56 are guided by the guide rails 10.
Since the guide grooves 13 and 12 are moved to the ends of the guide grooves 13 on the second winding pipe 28 side, the fully closed state is achieved. At this time, the screen 54 is supported by the intermediate pipe 68 and is prevented from hanging down in FIG. In addition, screen 5
4 is closed, the controller's "stop" switch is turned on to stop the operation of the second operator, unwinding the screen 54 from the first take-up pipe 20 and the wire take-up drums 34 and 35. By stopping the winding of the wires 64 and 66 onto the screen 54, the screen 54 can be stopped at a desired position. Next, when opening the screen 54, "open" of the controller
Turn on the switch. As a result, the first operator 24 operates, the first winding pipe 20 rotates in the winding direction of the screen 54 (counterclockwise direction in FIG. 1), and the second operator is maintained in the weak braking state. Therefore, since the screen 54 is wound around the first winding pipe 20,
The wires 64 and 66 are unwound from the wire winding drums 34 and 35, respectively, while maintaining these tensions. Therefore, the weight bar 56 is
Is guided by the guide grooves 13 of the guide rails 10 and 12 and moves toward the first winding pipe 20. Screen 5
4, all of which is wound around the first winding pipe 20 and the wires 64 and 66 are all unwound from the wire winding drums 34 and 35, whereby the rollers 58 of the weight bar 56 guide the guide rails 10 and 12. Since the groove 13 is moved to the end of the groove 13 on the first winding pipe 20 side, it is in a fully opened state. In addition, while the screen 54 is being opened, the "stop" switch of the controller is turned on to stop the operation of the first operator 24 to wind the screen 54 around the first winding pipe 20 and wind the wire. By stopping the unwinding of the wires 64 and 66 from the drums 34 and 35, the screen 54 can be stopped at the desired position. When the screen is stopped, the winding pipe in the weak brake state stops after rotating slightly in the direction opposite to the rotating winding pipe, so that the wires 64 and 66 and the screen 54 are kept in a tensioned state. It

In the above embodiment, the insertion holes 46 and 48 into which the wires 64 and 66 can be inserted are formed at two positions in the longitudinal direction of the wire stopper 44, but the invention is not limited to this. Three or more insertion holes may be formed in the wire stopper, an insertion hole may be formed in the width direction of the wire stopper, or the insertion hole may be omitted.
The structure may be such that the wires 64 and 66 are simply sandwiched between the wire stopper and the drum member. Further, in the above embodiment, both the first winding pipe 20 and the second winding pipe 28 are selectively rotatable by the operator 24 according to the opening / closing direction of the screen, but the invention is not limited to this. Instead, for example, the first winding pipe may be provided with a winding spring that constantly urges the first winding pipe in the screen winding direction, and only the second winding pipe may be rotationally driven by the operator. Further, the first winding pipe may be provided with a winding spring that constantly urges the first winding pipe in the screen winding direction, and the second winding pipe may be manually driven to rotate. Further, both the first take-up pipe and the second take-up pipe may be rotationally driven by the operator at the same time. Further, although one intermediate pipe 68 is provided in the above embodiment, the number of intermediate pipes 68 is not limited to this, and two or more intermediate pipes 68 may be provided, or need not necessarily be provided. Further, in the above embodiment, the case where the roll screen is used for the skylight has been described, but the present invention is not limited to this, and it may be used for an inclined window or an ordinary window. In this case, the guide rail is not necessarily provided. No need. When the roll screen of the present invention is used for an inclined window or an ordinary window, the screen may be opened / closed not only in the vertical direction but also in the horizontal direction. Further, in the above embodiment, the wire winding drum 3
Although 4 and 35 are attached to the second take-up pipe 28, the present invention is not limited to this. For example, the wire take-up drums may be connected by a rotary shaft, and the wire take-up drums may be separately provided. It may be driven by the operator. Further, in the above embodiment, the two wires are connected to the weight bar, but the present invention is not limited to this. For example, only one wire may be connected to the intermediate position in the longitudinal direction of the weight bar, or three wires. You may connect the above wire.
