Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a support cord holding device for attaching the lower end of a ladder-shaped support cord supporting the slats of a horizontal blind to the lower plate of the blind. The lower end of the support cord is shaped like a ring that goes around the lower side of the blind lower plate, and a plate-shaped cord holder is attached to the lower side of the lower plate from above, and the lower end of the support cord is connected to the lower plate. This invention relates to a support cord holding device for a horizontal blind which is held between cord holders.

[Conventional technology]

Horizontal blinds have ladder-shaped support cords arranged near both ends in the width direction, or in the middle if necessary, and each slat is supported on each middle cord of the ladder-shaped support cords, and the lowest end A lower plate is placed on the lower plate, and the vertical cords at the front and rear of each ladder-shaped support cord are attached to the lower plate.

The slats of the blind are raised and lowered by pulling a lifting cord attached to the lower plate at the lower end into a head box provided at the top of the blind, or lowering it. This is done by relatively moving the front and rear vertical cords up and down. In such known horizontal blinds, the lower ends of the vertical cords before and after the ladder-shaped support cord must be firmly fixed to the lower plate. Conventionally, in order to attach a ladder-shaped support cord to the lower plate in this way, the lower ends of the vertical cords before and after the ladder-shaped support cord are made into a ring shape that goes around the lower side of the lower plate, and a plate-shaped cord holder is attached from above. is attached to the underside of the lower plate, and a ring-shaped vertical cord is firmly held between the lower plate and the cord holder. In this case, if the lower end of the ladder support cord is not firmly fixed between the cord holder and the lower plate, each time the slat is tilted by relatively moving the front and rear vertical cords of the ladder support cord, The relative position of the ladder-shaped support cord and the lower plate may shift, and in extreme cases, the lower plate may tilt to a vertical position even though the slats are in a non-tilting position, that is, in a horizontal position in the longitudinal direction. Put it away. In such a state, the tilting action of the slat becomes impossible.

[Problem that the invention attempts to solve]

In recent years, horizontal blinds have also come to be used for slanted or horizontal windows. In such blinds, a guide wire or guide rod is used that passes through the slats and the bottom plate to prevent the middle section from sagging. Also,
In blinds used in windy areas, even vertical blinds may use guide wires or guide rods to prevent them from being blown away by the wind. In horizontal blinds that use guide wires or guide rods, the lower plate cannot be tilted because it has a certain thickness at the top and bottom, and accordingly, a ladder-shaped support cord is used. The vertical cords cannot be moved relative to each other, that is, the slats cannot be tilted.

The present invention is a horizontal blind in which the lower end of the ladder-shaped support cord is attached to the lower blind plate so that the slats can be tilted sufficiently even in horizontal blinds whose structure does not allow the lower plate to tilt as described above. The present invention aims to provide a support cord holding device for the following.

[Means for solving problems]

As a means to solve the above-mentioned problems, the present invention provides a guide wire or guide rod that penetrates the slats and lower plate of a horizontal blind and is stretched in the vertical direction of the window frame, etc., and a ladder that supports the slats. The lower end of the support cord is shaped like a ring that goes around the lower side of the lower plate, and a plate-shaped cord holder is attached to the lower side of the lower plate from above, and the lower end of the support cord is attached to the lower plate. In the support cord holding device for a horizontal blind which is held between the cord holder and the cord holder, between the cord holder and the lower plate,
A support cord holding device for a horizontal blind is provided, characterized in that a groove is formed through which the annular lower end of the support cord freely passes.

〔Example〕

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of a support cord holding device for a horizontal blind according to the present invention will be described with reference to the drawings.

FIG. 1 is a cross-sectional view showing one embodiment of the device of the present invention. In the figure, 1 indicates a slat of a horizontal blind, 2 indicates a ladder-shaped support cord supporting the slat, and the support cord 2 is a front and rear vertical cord 2a. , 2b and a middle cord 2c that horizontally connects them, and supports the slat 1 on the middle cord 2c. This ladder-shaped support cord is currently well known and widely used in horizontal blinds. A blind lower plate 3 is attached to the lower end of this ladder-shaped support cord, and a cord holder 4 is attached to the lower plate 3.
Attach it to the bottom of the Generally, the cord holder 4 is formed into a plate shape from an elastic material such as resin, and is attached to the lower plate 3 by fitting hook-shaped legs rising from its front and rear edges into the front and rear grooves of the lower plate. Figure 2 shows
In the plan view of this cord holder, 4a and 4b indicate its hook-shaped legs.

The support cord retention device according to the invention is particularly provided with a guide wire or guide rod passing through the slats and the bottom plate to prevent the blind from sagging when used on inclined or horizontal windows;
Alternatively, the guide wire is used in a vertical blind to prevent it from being blown away by the wind, and numeral 5 in FIG. 1 indicates such a guide wire.

In the support cord holding device for a horizontal blind according to the present invention, the lower end of the support cord 2 is formed into a ring shape that goes around the lower side of the lower plate 3 of the blind, and the support cord is placed between the cord holder 4 and the lower plate 3. It is characterized by forming a groove through which the annular lower end can freely pass.

In the illustrated embodiment, the vertical cord 2a on the front side of the ladder-shaped support cord is made long and shaped into a ring that goes around the lower ring of the lower plate 3. 2b. Therefore, a groove 4c is formed on the inner surface of the cord holder 4, extending from its front edge to its rear edge, so that the ring-shaped lower end of the support cord can freely pass therethrough.

In addition, in the illustrated example, the groove through which the ring-shaped lower end of the support cord can freely pass is formed on the inner surface of the cord holder 4, but such a groove is formed in the recess provided on the lower surface of the lower plate 3. It can be formed by a groove, or it can be formed on both the inner surface of the cord holder 4 and the lower surface of the lower plate.

As described above, when the support cord holding device according to the present invention moves the front and rear vertical cords 2a and 2b of the ladder-shaped support cord 2 relatively up and down in order to tilt the slat, the ring shape of the support cord 2 changes. The lower end of the slide slides in the groove formed between the lower plate and the cord holder, thus causing vertical relative movement of the vertical cords before and after the support cord, even though the lower plate does not tilt. First, the slat can be tilted to any desired angle.
