Description

[Detailed description of the invention] [Field of application of the invention] The present invention supports a large number of runners in a horizontally installed head rail so that they can run freely, suspends and supports a vertical louver from each runner, and connects the runners to the head rail. The louvers are opened and closed by traveling along the head rail, and each louver is rotated around its vertical axis at the same time by rotating a rotation shaft provided in the head rail to adjust light shielding. The present invention relates to a runner used in a vertical blind.

[Background of the idea]

In vertical blinds of the above type, accidents often occur in which the louvers are blown by the wind and fall off the runners.

[Purpose of invention]

An object of the present invention is to provide a runner for a vertical blind that prevents the accident of the louver falling off the runner and allows the louver to be attached to and detached from the runner with a simple operation when necessary.

[Summary of the idea]

The feature of the vertical blind louver according to the present invention is that a large number of runners are movably supported within a horizontally installed head rail, a vertical louver is suspended and supported from each runner, and the runners are mounted along the head rail. The louvers can be opened and closed by running the head rail, and each louver can be rotated around its vertical axis at the same time to adjust light shielding by rotating a rotation shaft provided in the head rail. In the runner used for vertical blinds, a vertical louver hanging shaft is provided in the center of the runner body, and the vertical louver hanging shaft is rotated around the vertical axis by the above-mentioned rotation shaft, and the lower end of the hanging shaft is forms a hook for hooking the hook on the top of the louver, and
An elastic closing member for elastically closing the upward opening of the hook at all times is provided at the lower end of the runner, separate from the hook, and surrounding the hook on a horizontal plane.

[Example of idea]

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

FIG. 5 shows an outline of the general structure of a vertical blind. In the figure, 1 is a horizontally installed head rail, 2 is a large number of runners supported in the head rail so that they can run freely, and 3 is each runner. Vertical louvers are suspended from the runner, 4 is a pivot shaft provided in the head rail to rotate each louver in unison about its vertical axis, and 5 is an operating cord. Although a cord may be used as a means for opening and closing the blind by running the runner 2 along the head rail 1, a screw shaft is generally used, and the blind is opened and closed by rotating the screw shaft. It is normal to open and close the blinds.

In this type of vertical blind,
Accidents often occur in which the louver 3 is blown by the wind and the hook provided at the upper end of the louver 3 falls off the hook provided on the runner.

The present invention attempts to eliminate such deficiencies of conventional vertical blinds, and examples of its runners are shown in FIGS. 2-4.

In Figures 2-4, 1 is a head rail;
2 indicates a runner, and 3 indicates a louver.

The runner is generally formed by integral molding of plastic, and has a central portion that engages with the rotation shaft 4 through, for example, a worm and a worm wheel (not shown) to rotate the rotation shaft 4. A vertical louver hanging shaft 6 is provided which can be rotated about a vertical axis by means of a screwdriver, and a hook 8 for hooking a hook 7 on the upper part of the louver 3 is formed at its lower end. Since the structure of the louver hanging shaft 6 itself having the hook 8 is well known, a detailed explanation thereof will be omitted.

In conventional vertical blinds, the louver was suspended from the runner by simply hooking the hook 7 of the louver 3 onto the hook 8 of the runner. The hook will come off.

Therefore, in the present invention, an elastic closing member is provided to elastically close the upward opening 9 of the hook 8. The resilient closure member may be a plastic member 10 integrated into the lower end of the body of the runner 2, as shown in FIG.
Hook-shaped leaf spring 1 embedded at one end in the bottom of the body of
1 or may be a coil spring 12 as shown in FIG. In addition, in the figure, 13 indicates a screw shaft for opening and closing the blind.

The attachment and detachment of the louver in the case where a closing member for elastically closing the upward opening 9 of the hook is provided as described above will be described with reference to FIG.

When attaching the louver to the runner, use the louver 3
By pushing up the end of the elastic closing member 10 with the hook part 7, the hook part 6 is attached to the hook 7.
After introduction, the closing member 10 returns to its original position by its own elasticity and closes the opening 9 in the upper part of the hook, thus preventing the louver from falling off. When taking out the louver, the opening 9 at the top of the hook is opened by pushing up the end of the closing member 10 with a finger, and the hook part of the louver can be easily removed.

[Effect of idea]

As described above, according to the present invention, the upper part of the hook that hooks the upper part of the louver of the vertical blind is always closed by the elastic closing member, so that the louver does not fall off due to wind. This will be prevented. However, since this closing member can be elastically easily opened and closed, there is no problem in attaching and detaching the louver, and the louver can be easily attached and detached.

[Brief explanation of the drawing]
