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 model, as shown in Utility Model Publication No. 1919, the guide wire passes through the body of the weight bar, so the force that moves the weight bar in the left and right direction acts directly on the guide wire. . Therefore, when a winding misalignment occurs on the screen and a force is applied to move the weight bar in the left-right direction, the frictional resistance between the weight bar and the guide wire increases, making it extremely difficult to operate the screen.

An object of the present invention is to provide a roll blind that can be installed on an inclined surface, and that even if the screen becomes misaligned, the operation of the screen will not be affected at all.

In order to achieve the above object, the roll blind of the present invention includes a weight bar consisting of a weight bar body having a length shorter than the interval between the guide wires, and a weight bar holder fitted to both ends of the weight bar body so as to be slidable relative to each other in the axial direction. The guide wire stretched across the inclined surface passes only through the weight bar holder and does not pass through the weight bar body.

If the weight bar body moves to either the left or right side due to misalignment of the screen, the fit between the weight bar and the left and right weight bar holders will shift, and one will become deep and the other shallow, but the guide line will not fit properly. Since the biasing force of the weight bar does not act, the frictional resistance between the guide wire and the side cover does not increase.

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 line 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 body 20 has a weight bar holder 21 fitted in a cap shape to both ends thereof, and the total length of the weight bar body 20 is approximately the same as the width of the screen 14, and is shorter than the distance between the guide lines 17 on both sides. Although a gap must be provided between the end surface of the weight bar body 20 and the inner bottom surface of the weight bar holder 21, the overall length of the weight bar 15 does not necessarily need to be shorter than the distance between the guide lines 17.

As shown in FIG. 2, the support bar 10 is fixed to the installation surface of a building 30 with screws or the like, and a bracket 11 is attached to the front groove of the support bar with a nut. 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 the weight bar holder 21
It passes through a through hole 22 in a thick end face portion, 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, the installation surface, and when it is released, the screen 14 is rolled up along the installation surface by a spring built into the roll blind 12.

Further, as shown by the arrow in FIG. 3, the weight bar holder 21 is fitted to the end of the weight bar body so as to be slidable in the axial direction, and the screen 14 is fitted into the long groove 23 at the top of the weight bar holder 21. .

It is also possible to install the roller blind on an inclined surface 30, as shown in FIG. At this time,
Support bar 10 integrated with upper guide wire fixture 16
is fixed to the inclined surface 30, and then the lower guide wire fixture 18 is fixed to the inclined surface 30 via the adapter 19 so that the guide wire 17 is parallel to the inclined surface 30.
When the cord 13 is pulled, the weight bar 15 moves up and down along the guide line 17, that is, the inclined surface 30, and the screen 14 opens and closes.

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 holder 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 movement of the guide wire 17 and the weight bar holder 21, there is no change in the sliding movement between the guide wire 17 and the weight bar holder 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 if the screen becomes misaligned, the weight bar will push the guide wire sideways and the sliding resistance of the weight bar will increase. Unlike conventional models, even if the screen winds misaligned, the position of the guide wire and the guide wire through hole in the weight bar does not change, so raising and lowering the weight bar, i.e. opening and closing the screen, is always easy. It has excellent effects not found in conventional products.
