Description

[Detailed description of the invention] [Industrial application field] The present invention has a plurality of horizontal slats, which can be raised and lowered, and each slat can be tilted at the same time to adjust light shielding. This relates to horizontal blinds.

[Conventional technology]

Generally, in horizontal blinds, a plurality of slats are supported vertically at regular intervals by ladder-like support cords hanging from a head box, and the slats are passed through elevating cord insertion holes provided in each of these slats to connect the slats at the lower end. The structure is such that each slat is folded upward in sequence by pulling a lifting cord attached to the lower plate located at the lowest end into the headbox.

[Problem that the invention attempts to solve]

In this type of horizontal blind,
In recent years, thin aluminum plates with a thickness of 200 to 150 microns have been used as slat materials. However, in a horizontal blind using such a slat material, each time the slat is raised or lowered, the lifting cord rubs against the sharp edge inside the lifting cord insertion hole of the slat, causing the lifting cord to break after years of use. However, in the upper part of the lifting cord, the number of slats that rub against each other when going up and down is small, but in the area near the lower end of the lifting cord, almost all of the slats rub against each other each time the lifting cord is moved up and down. The phenomenon of cutting is most noticeable at the lower end of the lifting cord, especially at the part around 100mm from the part attached to the lower plate.

In addition, when such a horizontal blind is applied to an inclined window, in other words, a guide cord is stretched along the slope of the inclined window, a guide cord insertion hole is provided in each slat, and each slat is inserted along the guide cord. When ascending and descending diagonally, in addition to the problem of frayed elevation cords as described above, the load of the folded slats is applied to the guide cord when the folded slats are lowered, causing damage to the slats and the lower board. There is also the problem that the slats will not come down due to their own weight alone.

[Object of the invention] The first object of the invention is to reduce the number of cuts in the lifting cord in such a horizontal blind.

A second object of the present invention is to facilitate the raising and lowering of the slats when a horizontal blind is applied to an inclined window.

[Structure of the idea]

The horizontal blind according to the present invention supports a plurality of slats vertically at regular intervals by a ladder-like support cord hanging from a head box, and extends through holes provided in these slats to position the lower end at the lowest end of the group of slats. In a horizontal blind in which each slat is folded upward in sequence by pulling a lifting cord attached to a lower plate into a head box, the plurality of slats are folded above the cord attachment part of the lower plate. The present invention is characterized in that a cylindrical lifting cord cover having substantially the same dimensions as the bottom is provided.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows an embodiment of a horizontal blind according to the present invention. In the figure, 1 is the head box of the blind, 2 is the slat, 3 is the lifting cord, 4 is the ladder-like support cord, 5 is the lower plate, and 6 is the operation cord.
A plurality of slats 2 are supported vertically at regular intervals by ladder-like support cords 4 hanging from the headbox 1. The lifting cord 3 extends downward from inside the head box 1 through holes provided in each slat 2, and is attached to the lower plate 5 at its lower end.

The lifting and lowering of the slats is carried out by pulling the lifting cord 3 into the headbox 1 or pulling it out from the headbox using the operation cord 6.

The folding allowance (the fourth
A cylindrical cord cover 7 having substantially the same dimensions l (shown in FIG. 3) as shown in FIG. 3 is attached.
The upper end of the cord cover 7 is preferably rounded so that it can easily enter the insertion hole of the slat.

When used as a normal horizontal blind, the lower end of the lifting cord 3 is inserted through a cylindrical cord cover 7 and fixed to the lower plate 5, as shown in FIG. As mentioned above, it is preferable that the length l of the lifting cord cover 7 is approximately equal to or less than the folding width W of the slat when the slat is folded up (FIG. 4).

In the above-mentioned blind, in particular, the portion near the lower end of the lifting cord that rubs against almost all of the slats during each lifting operation is protected by the cylindrical cover 7, so that the lifting cord is prevented from fraying.

FIG. 5 shows another embodiment of the blind of the present invention. This shows the application of the present invention to horizontal blinds for slanted windows.

In the embodiment shown in FIG. 5, the blind is opened and closed by sliding the slats 2 and the lower plate 5 along a guide cord 11 stretched along the slope of the inclined window 10.

In this embodiment, a cylindrical cord cover 12 having substantially the same size as the folding margin of the slats is attached to the lower plate 5 where the guide cord 11 passes. Similarly, the lifting cord is passed through the cord cover 12 and its lower end is fixed to the lower plate 5.

In this embodiment, when the slat is folded up, the slat does not come into direct contact with the guide cord but rests on the cord cover 12.
Rubbing between the slats and the guide cord is prevented, and even on a relatively gentle slope, the slats of the blind can be lowered only by the weight of the slats and the lower plate.

[Effect of idea]

According to the present invention, when the blind is raised or lowered, the lower part of the lifting cord that is connected to almost all the slats is covered by the cord cover provided on the lower plate, so the life of the lifting cord is extended and the life of the blind itself is extended. You can obtain blinds that can withstand the use of In addition, in the case of a sloped window blind, since it is possible to prevent the slats and the guide cord from slipping, it is possible to lower the blinds even on a gentle slope using only the weight of the slats and the lower plate.
