Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a blind installed in a window, such as a bay window, having a plurality of window surfaces connected at an angle to each other.

As a blind attached to such a window,
Recently, blinds made of a combination of a plurality of unit blinds that are attached to each window surface have come into use. Such blinds are simply made by connecting the head boxes of multiple blinds made to fit the width of each window surface with hinges at the joints of the window surfaces. It is configured to raise and lower the slats and tilt the slats. However, although it is preferable to lift and lower the slats for each window surface, it is better to tilt the slats for all unit blinds at the same time, not only for convenience of operation but also for economical reasons. It is also preferable. In particular, in the case of the above type of blinds that are installed on bay windows, the width of the front window surface is wide and the width of the left and right side window surfaces is generally narrow. If a slat tilting mechanism is provided independently for each unit blind installed on a window surface, not only will it be difficult to operate and economically undesirable, but the cord for operating the slat tilting will hang down on the narrow window surface. This is an eyesore and is not desirable for the overall design of the blind.

In addition, as a conventional blind of this type, one has been proposed in which the head boxes of the unit blinds are foldably connected with hinges at the joints of the window surfaces to integrate multiple unit blinds. In these types of blinds, the headboxes can only be bent horizontally relative to each other, and multiple workers must hold all the headboxes in a horizontal position when attaching the blinds to the window. Because it doesn't happen,
The installation work is complicated, and it is completely impossible for a single worker to install the blinds.

The purpose of the present invention is to eliminate the above-mentioned drawbacks in blinds installed on windows with multiple window surfaces, especially bay windows, and to control all units by a single operating means provided at one location of the blind. To provide a blind which can be tilted, can be easily attached to a window by one worker, and has an excellent appearance.

The blind according to the present invention is a blind installed in a window having a plurality of consecutive window surfaces at an angle to each other, and is composed of a plurality of unit blinds attached to each window surface, and each unit blind has a plurality of unit blinds attached to each window surface. It has a headbox attached to the upper part of the window surface, a plurality of slats suspended and supported from the headbox, and a slat tilting shaft rotatably supported within the headbox for tilting the slats all at once. death,
At mutually adjacent ends of the plurality of unit blinds, the slat tilting shafts of the respective unit blinds are interconnected via flexible shafts, and the ends of the head boxes of the respective unit blinds are connected by bellows-like members. They are characterized by being interconnected.

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

FIG. 1 shows an embodiment of the blind according to the present invention. This blind is attached to a bay window having three consecutive window surfaces at an angle to each other, and is composed of three unit blinds A, B, and C attached to each window surface.
Each unit blind has a head box 1a, 1b, 1c attached to the upper part of each window surface.
and a plurality of slats 2a suspended from the headbox by well-known ladder-shaped support cords.
2b, 2c, and slat tilting shafts 3a, 3b, 3c rotatably supported within the head box for tilting the slats all at once.

As is well known, a slat tilting drum is mounted on the slat tilting shaft, and a loop at the upper end of a ladder-shaped support cord supporting the slat is hung over the drum to rotate the slat tilting shaft. This makes it possible to perform a tilting operation of the slat via the ladder-shaped support cord. Further, as is well known, the slat can be raised and lowered by a slat lifting cord. In the figure, numeral 4 indicates a lifting operation code for lifting and lowering the slat.

In the blind of the present invention, at mutually adjacent ends of the unit blind, that is,
In the example shown in FIGS. 2 and 3, at the mutually adjacent ends of unit blinds A and B, the slat tilting shaft 3 of each unit blind is
a and 3b are connected to each other via a flexible shaft 5, and the ends of head boxes 1a and 1b of each unit blind are connected to each other by a bellows-like member 6.

In the blind of the present invention, as mentioned above,
The head boxes of the unit blinds are interconnected by bellows-like members, and the slat tilting shafts are integrally connected to each other by flexible shafts, so that in the illustrated example, the blinds consisting of three unit blinds can be connected to each other at one location. The tilting shafts 3a, 3b, 3c are controlled by the provided tilting operation cord 7.
By rotating the slats all at once, the entire slat can be tilted.

As described above, according to the present invention, the slat tilting shafts are integrally connected by a flexible shaft so that the slats of all unit blinds can be tilted from one place, and the slats of each window surface are connected to each other by a flexible shaft. No matter what the intersection angle of
The headboxes are connected together by bellows-like members so that each headbox can be properly installed on each window surface.

With the above configuration, the present invention can achieve the following effects.

(1) Since the ends of adjacent head boxes are connected by a bellows-shaped member, one member can handle multiple window surfaces that are at an angle to each other, and therefore there is no need to increase the number of parts. To provide horizontal blinds that can accommodate multiple window surfaces.

(2) Since a bellows is used to connect the head boxes, it is possible to provide a horizontal blind with a clean design.

(3) Since the bellows-shaped member can be made from a molded product, there is no need to manufacture a special horizontal blind for use on multiple window surfaces; simply connect the head boxes of conventional blinds using the bellows-like molded part. Therefore, it is possible to easily manufacture an integrated horizontal blind for multiple window surfaces, for example, a bay window.

(4) Since a bellows is used as the head box connecting member, each head box can be bent freely not only horizontally but also vertically. By simply supporting the headbox horizontally, the blind installation work can be carried out with the other headboxes hanging downward from the end, and the work can be done while holding all the headboxes in a horizontal position as in the conventional method. Since this is not necessary, even one worker can easily install the blind.
