Description

[Detailed Description of the Invention] The present invention relates to an improvement of a roll blind that can be installed on an inclined surface.

Roller blinds installed on a slope require a weight bar to be raised and lowered along the slope. For this purpose, a guide wire is stretched along the inclined surface, and the guide wire is passed through both ends of the weight bar to raise and lower the weight bar. However, in the conventional type, the operation cord of the screen hangs down from the center of the inclined surface, which makes it look bad and makes it difficult to operate.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a roll blind that can be installed on an inclined surface, with an operating cord hanging down along one side of the inclined surface rather than from the center.

In order to achieve the above object, the roll blind of the present invention is provided with a hole through which an operating cord is passed through a fixture that locks the lower ends of the two guide wires passing through the weight bar. One end of the operating cord is locked in the through hole of one fixture, and the other end passes through the weight bar in the axial direction and is pulled out from the through hole of the other fixture.

The blind of the present invention will be explained based on an embodiment shown in the drawings. As shown in FIG. 1, the roll blind of the present invention includes a support bar 10 attached to the top of a window, etc., brackets 11 provided on both sides of the support bar, and a roll body 12 bearing on the brackets. It includes a screen 14 wound around the roll body and a weight bar 15 attached to the tip of the screen. Upper guide wire fixing devices 16 are installed at the bottom of both sides of the support bar 10.
is fixed, and the guide wire 1 is connected from the fixtures 16 on both sides.
7 extends parallel to the installation surface. The tip of the guide wire 17 is locked to the lower guide wire fixture 18 with a fixing plate 28 and a screw. In order to apply tension to the guide wire, the upper end of the guide wire is locked to the upper guide wire fixture via an elastic material. One end of the cord 13 for operating the screen 14 is locked in the through hole 27 of one of the lower guide wire fixtures 18 . The cord 13 passes through the weight bar 15 and exits to the opposite side, and the cord 13 passes through the through hole 2 of the other fixture 18.
It is drawn from 7. The other end of the cord 13 is the guide 2
4 and the cord stopper 25, and is wound onto the reel 26. The weight bar 15 is the weight bar body 20
The weight bar main body 20 has a weight bar holding portion 21 fitted in a cap shape at both ends thereof, and the total length of the weight bar main body 20 is approximately the same as the width of the screen 14, and is shorter than the interval between the guide lines 17 on both sides.

As shown in FIG. 2, the operating cord 13 passes through an axial gap on the lower side of the weight bar body 20 and hangs downward from a guide hole groove 29 provided on the end surface of the weight bar holding portion 21. As shown in FIG. The lower surface of the guide hole groove 29 is finished in an arc shape so that the operation cord 13 can slide smoothly. The lower guide wire fixture 18 is fixed to the adapter 19 so that its through hole 27 is located directly below the guide hole groove 29. Therefore, since the frictional resistance against sliding of the operating cord 13 is small, when the weight bar 15 is moved up and down via the operating cord 13, it opens and closes easily along the guide line 17. Since the operating end of the operating cord 13 is located on one side of the installation surface, it is easy to operate and the overall appearance of the roll blind is streamlined.

As shown in FIG. 3, the support bar 10 is fixed to the inclined surface of a building 30 with screws or the like, and the bracket 11 is attached to the front groove of the support bar with nuts. The upper guide wire fixture 16 is attached to the lower groove of the support bar, and the upper end of the guide wire 17 is locked to an elastic body whose one end is fixed inside the fixture. The guide line 17 is connected to the weight bar holding section 2
It passes through a through hole 22 in the thick end face of No. 1, and its lower end is locked to the lower guide wire fixture 18 via a fixing piece 28. The lower fixture 18 is fixed to an adapter 19, which is fixed to the building 30 by screws or the like. The operating cord 13 that has passed through the weight bar 15 is pulled out from the through hole 27 of the lower fixture 18. When the operating cord 13 is pulled, the screen 14 is pulled out along the guide line 17, that is, along the sloped surface, and when released, the screen 14 is rolled up along the sloped surface by a spring built into the roll blind 12.

As shown in FIG. 4, the lower end of the guide wire 17 is held down by the fixing piece 28 in the groove on the upper surface of the lower guide wire fixture 18, so while adjusting the tension of the guide wire 17, the lower end of the guide wire 17 is held down by the fixing piece 28. It can be fixed without being exposed.

As shown in FIG. 5, if there is no miswinding of the screen 14, the gap between the screen 14 and the guide wire 17 and the gap between the end surface of the weight bar body 20 and the inner bottom surface of the weight bar holding part 21 will be as specified. When the screen 14 is misaligned, the screen 14 shifts to the left or right as shown by arrows in FIGS. 6 and 7. As a result, as shown in FIG. 6, the fit between the weight bar holding portion 21 and the weight bar body 20 becomes deeper on one side, and shallower on the other side as shown in FIG.
Since this has no effect on the guide wire 17 and the weight bar holding portion 21, there is no change in the sliding movement between the guide wire 17 and the weight bar holding portion 21. Therefore, the lifting and lowering of the weight bar 15, that is, the opening and closing of the screen 14, is always performed smoothly regardless of whether or not the screen 14 is twisted.

As mentioned above, the roll blind of the present invention can be installed not only on vertical surfaces but also on inclined surfaces, but the operation code is different from conventional ones and is located on one side of the installation surface instead of in the center. It not only has a sleek overall appearance but also is easy to operate, which is an excellent effect not found in conventional products.
