Description

[Detailed description of the invention] [Field of industrial application] The present invention horizontally supports a plurality of slats by means of ladder-like support cords near both ends of the slats and, if necessary, at an intermediate position, and This relates to a so-called horizontal blind, which is equipped with a lifting cord for raising and lowering the window.

[Conventional technology]

In general, horizontal blinds have a plurality of slats supported horizontally at regular intervals vertically by ladder-like support cords near both ends of the slats and, if necessary, at one or more locations in between. By moving the front and rear vertical cord parts of this ladder-shaped support cord relatively up and down, the slats can be tilted to adjust light shielding, and the lifting cord can be inserted through the lifting cord insertion hole provided in each slat. The slats are passed through vertically, and the lower ends thereof are fixed to a lower plate disposed at the lower ends of the rows of slats, and the slats are raised and lowered, that is, the blinds are opened and closed, by winding up or lowering the lifting cord. ing.

As mentioned above, the above-mentioned elevating cord has the function of controlling the elevating and lowering of the slats, and because it extends vertically through the elevating cord insertion hole provided at the same position on each slat, it also controls the horizontal movement of each slat. It also plays the role of regulating the slats and aligning a large number of slats in the vertical direction.

[Problem that the invention attempts to solve]

However, in the structure of the conventional horizontal blind as described above, when the slats are tilted to a vertical position, outside light leaks into the room through the elevating cord insertion hole, impairing the light-shielding function of the blind.
Furthermore, it is not desirable in terms of the appearance of the blind that a large number of elevating cord insertion holes are visible over the entire surface of the blind when the blind is closed.
In addition, in the conventional structure where the lifting cord passes through the lifting cord insertion hole provided in each slat, when the slat is tilted, the edge of the lifting cord insertion hole of each slat hits the lifting cord. There is also the problem that the tilting action of the slat is limited and therefore the slat cannot be tilted to a completely vertical position.

[Purpose of invention]

The purpose of the present invention is to eliminate the elevating cord insertion hole provided in the center of the slat in the horizontal blind of the above type, to prevent the leakage of outside light when the slat is tilted, and to prevent the leakage of outside light from the slat surface. To provide a horizontal blind which has excellent appearance since no holes are visible and whose slats can be tilted to a completely vertical position.

[Means for solving problems]

As a means to solve the above-mentioned problems with conventional horizontal blinds, the present invention supports a plurality of slats horizontally by ladder-like support cords near both ends of the slats and, if necessary, at an intermediate position. In a blind equipped with a lifting cord for raising and lowering the slat, instead of providing a lifting cord insertion hole in the center of the slat, a lifting cord guide piece made of a flexible material with a small hole through which the lifting cord is inserted is inserted from the side edge of the slat. To provide a blind, which is attached to the slats so as to protrude, and the lifting cord is arranged along the side edge of each slat through the lifting cord guide piece, so that all the slats can be moved up and down. .

[Example of idea]

The embodiments shown in the drawings will be described below.

FIG. 1 is a perspective view of a part of a horizontal blind according to the present invention. Similar to a normal horizontal blind, a plurality of slats 2 are moved vertically at regular intervals by a ladder-like support cord 1 near each end of the slats and, if necessary, at one or more locations in between. supported horizontally across the
Vertical cord portion 1 before and after this ladder-like support cord
By moving a and 1b relatively up and down, the slat is tilted to adjust the light shielding.

A lifting cord 3 is provided for raising and lowering the slats to open and close the blind. The lifting cord 3 extends vertically, and its lower end is attached to a lower plate (not shown) disposed at the lower end of the slat row, and the blind is opened and closed by winding up and lowering the lifting cord 3. However, in the blind according to the present invention, the lifting cord guide piece 4, which has a small hole through which the lifting cord is inserted, protrudes from the side edge of the slat, instead of providing a lifting cord insertion hole in the center of the slat. It is attached to the slats so that the The above-mentioned lifting cord guide piece 4 winds up and lowers the lifting cord.
When going up and down within the lifting cord guide piece 4, it can be moved up and down according to the lifting and lowering.

In the embodiment shown in FIGS. 2-4, the guide piece 4 is made of a flexible and stiff material, such as resin, metal, or other suitable material. FIG. 3 shows an embodiment of the guide piece 4, in which a protrusion provided on the guide piece 4 is inserted into a small hole provided in the slat and fixed to the slat by heat-sealing. This may be bonded with an adhesive or may be welded by other means.

FIG. 4 shows a state in which this slat is supported by a ladder-like support cord 1 and a lifting cord 3 is passed through a guide piece 4. The guide pieces may be attached to one side of the lateral edge of the slat in a different manner or symmetrically, and if necessary, an additional guide piece may be provided in the center.

5 to 8 show other embodiments of the blind of the present invention.

In Figure 5 A and B, the guide piece 4 is formed into a ring with a flexible cord, is inserted into a small hole provided in the slat from one end, and the other end is tied or welded so that it cannot pass through the small hole. An example is shown in which it is mounted on a slat as a large size.

FIGS. 6A, 6B, and 6C show an embodiment in which the slat is cut and raised, and a guide piece 4 made of a ring such as a cord is hooked to the cut and raised portion 5 to be attached to the slat. FIG. 7 shows a modification of the cutting process for attaching the guide piece shown in FIG. 6, and the guide piece 4 is attached in the same manner as in FIG. 6C.

Figures 8A, 8B, and 8C show an embodiment in which a protrusion 6 with a partially opened opening is formed on the slat by cutting and raising, and the guide piece 4 is attached to the slat using the opening 6a of this protrusion. .

Among the above-mentioned embodiments, FIGS. 2-4 show a configuration in which the guide piece 4 moves up and down due to its own flexibility as the lifting cord moves up and down, and FIGS. FIG. 8 shows a configuration in which the guide piece 4 itself is flexible and moves up and down by vertical swinging around its fulcrum. Such vertical movement is necessary to smoothly raise, lower, and tilt the blind.

[Effect of idea]

According to the present invention, since there is no lifting cord insertion hole in the center of each slat, when the slats are tilted to the vertical position, outside light will not leak into the room through the lifting cord insertion hole and the light blocking function will be impaired. Without,
It also has an excellent appearance because no holes are visible when it is closed.

However, the above-mentioned blind, like the conventional one, has vertical cord portions 1a, 1b of the support cord 1.
The slat can be tilted by moving the slat up and down relatively, but as shown in Figure 9, in the conventional slat, when tilting, the edge of the lifting cord insertion hole is not engaged with the lifting cord. In order to match
Although the slat cannot be tilted to a completely vertical position, according to the present invention, as shown in FIG. It is possible.
