Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vertical blind for adjusting the amount of light by moving or rotating a slat suspended from a hanger rail along the hanger rail.

[0002]

2. Description of the Related Art As one type of a vertical blind, by operating an operating means provided at one end of a hanger rail,
In some cases, the slat is pulled out along the hanger rail or the slat is rotated to adjust the amount of light collected.

In such a vertical blind, a large number of runners are movably supported by hanger rails, and slats are rotatably supported by each runner. When the moving operation means suspended on one side of the hanger rail is operated, the first runner is moved along the hanger rail, and the subsequent runner moves following the first runner to pull out or fold the slat. Is performed. At this time, the rear end runner is fixed to the base end side of the hanger rail.

[0004] When the angle operating means also suspended on one side of the hanger rail is operated, the slats suspended and supported by the respective runners are rotated in the same phase.

[0005]

In the vertical blind as described above, when it is necessary to open or close a window or perform a cleaning operation at a position where the slats are drawn out along the hanger rail, such a window is required. Since the slats are in the way, it is necessary to operate the moving operation means to temporarily collapse the slats.

[0006] Further, even when the slats are folded, when the above operation is performed in the vicinity of the base end of the hanger rail, the work is performed while pushing a large number of slats folded in the base end of the hanger rail. Need to do.

[0007] Therefore, there is a problem that the slats that are pulled out or are folded may obstruct the operations such as opening and closing of windows and cleaning. It is an object of the present invention to provide a vertical blind which can easily move a slat to a position where the slat does not hinder the work at the time of opening / closing a window, cleaning, and the like.

[0008]

According to the present invention, slats are respectively suspended from a plurality of runners movably supported in a hanger rail, and the slats are pulled out along the hanger rail by slat moving means. In the vertical blind capable of being folded, a rear end runner supporting a rear end slat is provided with a holding means for detachably holding the rear end runner on a base end of a hanger rail.

According to a second aspect of the present invention, the holding means has a structure in which a suction member is attached to one of the rear end runner and the hanger rail, and a member to be sucked is attached to the other. Claim 3
In the above, the attracting member is constituted by a magnet, and the attracted member is constituted by an attracting plate formed of a magnetic material.

[0010]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. In the vertical blind shown in FIG. 1, a large number of runners 2 are movably supported in a hanger rail 1, and a slat suspension shaft 3 is rotatably supported on each runner 2. The slats 4 are suspended from the respective slat suspension shafts 3.

A tilt pole 5 is suspended from the base end of the hanger rail 1, and the tilt pole 5 is attached to an input shaft of a gear box 6 disposed inside the hanger rail 1.

A bevel gear is built in the gear box 6, and its output shaft is attached to a tilt shaft 7 rotatably supported in the hanger rail 1, as shown in FIG. Therefore, when the tilt pole 5 is rotated, the tilt shaft 7 is rotated via the gear box 6.

The tilt shaft 7 is inserted through each of the runners 2. When the tilt shaft 7 is rotated, the slat suspension shaft 3 is rotated via a worm mechanism built in each runner 2.

At the base end of the hanger rail 1, an endless operation code 8 is hung. The operation code 8 is guided near the inner side surfaces on both sides of the hanger rail 1 toward the tip of the hanger rail 1, and one of the two ends. Is fixed to the leading runner 2a and the endless
Is mounted on a pulley 9 rotatably supported at the tip end of the pulley.

Therefore, when the operation code 8 is operated, the leading runner 2a moves together with the operation code 8 moving within the hanger rail 1. The runners 2a, 2 are connected by a spacer 10 so that the maximum distance between them is constant. Therefore, the leading runner 2a
Moves toward the tip end side of the hanger rail 1, the subsequent runners 2 move in the same direction at regular intervals. When the leading runner 2a moves toward the base end of the hanger rail 1, the subsequent runners 2 are sequentially pushed back by the leading runner 2a.

The hanger rails 1 in each of the runners 2
An iron suction plate 11 is attached to a side surface on the base end side of the hanger rail 1 of the rear end runner 2b located closest to the base end. At the base end of the hanger rail 1, a magnet 12 is attached at a position facing the suction plate 11.

Therefore, the rear end runner 2b is always held at the base end of the hanger rail 1 with its attraction plate 11 being attracted to the magnet 12. Next, the operation of the vertical blind configured as described above will be described.

As shown in FIG. 3, when the slats 4 are pulled out by operating the operation cord 8 and the tilt poles 5 are operated to rotate the slats 4 along the hanger rail 1, the slats 4 are fully closed. . At this time, since the rear end runner 2b is attracted to the magnet 12, the hanger rail 1
At the base end.

In this state, when a space is required on the base end side of the hanger rail 1, the slats 4 suspended and supported by the rear end runner 2b are pulled toward the front end side of the hanger rail 1 so that the rear end runner 2b Is separated from the magnet 12, and several slats 4 are moved to the tip end side of the hanger rail 1 as shown in FIG. Then, a space where the slats 4 are not suspended and supported is formed on the base end side of the hanger rail 1.

As shown in FIG. 5, when space is required on the base end side of the hanger rail 1 with the slats 4 folded on the base end of the hanger rail 1, the slats 4 are hung on the rear end runner 2b. The supported slats 4 are pulled toward the tip end of the hanger rail 1, the rear end runner 2b is separated from the magnet 12, and all the slats 4 are moved toward the tip end of the hanger rail 1 as shown in FIG. Then, a space where the slats 4 are not suspended and supported is formed on the base end side of the hanger rail 1.

With the vertical blind as described above, the following operational effects can be obtained. (1) When a space is required at the base end of the hanger rail 1 where the slats 4 are pulled out and the slats 4 are not suspended and supported, the rear end runner 2b is separated from the magnet 12 and is suspended from the rear end runner 2b. By moving the slats 4 supported below and the slats 4 in the vicinity of the slats 4 toward the tip end of the hanger rail 1, the operation cord 8 is not operated and the slats 4 are folded.
The necessary space can be easily formed. Therefore, it is possible to prevent the pulled out slats from obstructing operations such as opening and closing of windows and cleaning. (2) When a space where the slats 4 are not suspended and supported is required at the base end of the hanger rail 1 in a state where the slats 4 are folded, the rear end runner 2b is separated from the magnet 12, and all the slats 4 are hanger-mounted. By moving the rail 1 toward the distal end, a necessary space can be easily formed. Therefore, it is possible to prevent the folded slat from hindering operations such as opening / closing a window and cleaning.

The above embodiment can be modified as follows. The magnet may be attached to the rear end runner 2b, and the suction plate may be attached to the hanger rail 1. The case of the rear end runner 2 b may be formed of a magnetic material, and the case may be configured to be attracted to a magnet attached to the hanger rail 1. -Removable suction means and adhesion means other than magnets may be used. The head runner may be screwed onto a screw shaft arranged over the entire length of the hanger rail, and the screw shaft may be driven to rotate so that the head runner moves along the hanger rail.

[0023]

As described in detail above, the present invention provides a vertical blind which can easily move a slat to a position where it does not hinder the work, such as opening / closing a window or cleaning. it can.
