Description

[Detailed description of the invention] This invention relates to blinds for slanted windows used on the ceiling of sunrooms, etc. In particular, horizontal blinds are installed along the slanted windows, and the slats are raised and lowered and tilted. This invention relates to blinds for slanted windows.

In horizontal blinds, a plurality of slats are held vertically at regular intervals by at least two ladder-shaped support cords, so-called ladder cords, and a plurality of slats are held vertically at regular intervals, and the slats are inserted through the lifting cord insertion hole formed in each slat. The slats are raised and lowered by pulling up or down a lifting cord extending from the slats, and the slats are tilted by operating a ladder cord.

The present invention aims to provide a blind for an inclined window in which a horizontal blind having the above structure is installed obliquely along an inclined window, and the slats are raised and lowered and tilted at this inclined position.

In order to apply the structure of a horizontal blind to an inclined window, it is necessary to hold the entire blind in an inclined state so that the middle part of the blind does not sag, and to move the slats up and down and tilt them in this inclined state. We have to make it possible. For this purpose, the blind according to the present invention is
A slanted guide wire is stretched along the slanted window, a guide wire insertion hole is provided at the center of each slat in the width direction, and each slat is supported on the guide wire at the center of the width direction. Each slat is configured to slide over the guidewire. According to such a configuration, the slat can be moved up and down along the inclined path by operating the lifting cord, and the slat supported on the guide wire can be moved up and down by operating the ladder cord. Each slat can be tilted using the upper edge of the guide wire insertion hole provided in the center of the slat as a fulcrum. However, in such a configuration, when the slat is moved up and down, the edge of the slat's lifting cord insertion hole comes into contact with the lifting cord, and the resulting frictional resistance hinders the lifting operation, making it difficult to smoothly lift and lower the slat. can't do it. Further, during tilting, the edge of the guide wire insertion hole contacts the guide wire and prevents the slat from tilting, making it impossible to achieve sufficient tilting of the slat. To this end, the blind of the present invention has a guide wire insertion hole provided in each slat in the form of a long hole extending from the widthwise center of the slat toward the lower edge of the slat, and is located at the widthwise center of the slat. The slat is supported on the guide wire at the upper edge of the elongated hole, and is configured to prevent the lower edge of the elongated hole from hitting the guide wire and obstructing the tilting movement of the slat when the slat is tilted. Furthermore, the blind of the present invention has the elevating cord insertion hole provided in each slat in the form of a long hole extending from the widthwise center of the slat toward the upper and lower edges of the slat, even when the slat is tilted. It is configured to prevent the lifting cord from coming into contact with the edge of the lifting cord insertion hole and obstructing the lifting operation even at certain times.

Hereinafter, the present invention will be described in detail with reference to the drawings.

FIG. 1 shows an embodiment of a blind for an inclined window according to the present invention, and in the figure, 1 indicates an inclined window such as the ceiling of a sunroom, and 2 indicates a blind. The blind 2 includes a head box 3, a ladder-shaped support cord extending obliquely downward from the head box, a so-called ladder cord 4, a plurality of slats 5 supported by the ladder cord, and a plurality of slats 5 provided at the lower ends of these slats. It has a bottom rail 6. Although not shown in FIG. 1, a lifting cord extends obliquely downward from the head box 3 through a lifting cord insertion hole provided in each slat, and is connected to a bottom rail 6 at its lower end. Thus, by pulling up or down the lifting cord, the slats are raised or lowered to open or close the blind, and by operating the ladder cord 4, the slats are tilted.

In order to hold the blind in an inclined position along the inclined window, a guide wire 7 is stretched obliquely along the inclined window. The guide wire 7 passes through a guide wire insertion hole provided in each slat, passes through the bottom rail 6, and is fixed to a lower fixing member 8.

As shown in FIG. 2, each slat 5 is formed with a guide wire insertion hole 9 in the form of an elongated hole extending from the center in the width direction toward the lower edge of the slat, and for passing the lifting cord 10 therethrough. An elevating cord insertion hole 11 in the form of a long hole extending from the center in the width direction toward the upper and lower edges of the slat is formed.

Since the sloped window blind of the present invention is constructed as described above, each slat 5 has an elongated guide wire insertion hole 9 located at the center of its width, as shown in FIG. is supported on the guide wire 7 at its upper edge and slides over the guide wire 7. Therefore, the plurality of slats 5 are maintained in alignment with each other along the inclined window and can be raised and lowered without disrupting this alignment. At this time, the lifting cord 10 is located at the center of the elongated lifting cord insertion hole 11 as shown in FIG. The slats are raised and lowered smoothly. Further, when the slats are tilted, each slat 5 is tilted on the guide wire 7 using the upper edge of the guide wire insertion hole 9 as a fulcrum, as shown in FIG. 4A. However, since this guide wire insertion hole 9 is formed in the form of a long hole, the lower edge of the guide wire insertion hole 9 will not hit the guide wire and prevent the slat from tilting, and the slat will be able to maintain a sufficient angle. Can be tilted. Furthermore, since the elevating cord insertion hole 11 is formed as a long hole extending vertically from the center of the slat, as shown in FIG.
Even when the slat is in a tilted state, the lifting cord 10 does not hit the edge of the lifting cord insertion hole 11 and obstruct the lifting operation.

As described above, the slanted window blind according to the present invention allows the slats to be smoothly raised, lowered, and tilted, and can be installed even on slanted windows with a small angle of inclination. In addition, the above-mentioned slanted window blinds are opened and closed by constantly applying a force in the closing direction to the blind due to the action of gravity acting on the bottom rail, and by lifting the bottom rail against the above force using a lifting cord. However, if a force other than gravity, such as a spring force, is applied to the bottom rail, the blind for inclined windows of the present invention can also be applied to horizontal windows.
