Description

[Detailed Description of the Invention] This invention relates to an attachment for an operating string of a horizontal blind, and more specifically, to an attachment for attaching the string to a bottom rail.

Conventionally, as shown in FIG. 1, the operating string of a manual horizontal blind has a drive shaft 4 having a polygonal cross section mounted on a support frame 5 in a top body 1 fixed to a ceiling 2 with screws 3. Tilting cables 7 hang down from some of the drums and are fixed to a bottom rail 8.

On the other hand, from the drum 6 provided at one end of the upper surface body 1, the tilting cable operating strings 9 are wound in opposite directions and suspended from each other.
10 is extended.

The lower ends of these tilting rope operating strings 9 and 10 are fixed by tying a knot in a cap 11 that is fitted and fixed to one end of the bottom rail 8.

On the other hand, the vertical operation string 12 is guided through the top body 1 in contact with a stopper device 13 attached to one end of the top body 1.
It is fixed by passing along the tilting cable 7 through the center of the slat 14 and inserting its tip into the cap 11 which is fitted and fixed to the bottom rail 8 and tying a knot.

In the figure, reference numeral 15 indicates knobs attached to the tilting cable operating strings 9 and 10, respectively.

In this way, in the conventional horizontal blind, even when the slats 14 are lowered, the tilting rope operating strings 9 and 10 and the vertical operating strings are sufficiently longer than the tilting rope 7 and hang below the bottom rail 8. When the slat 14 is pulled up toward the upper body 1, the operating string 12 is folded back as the bottom rail 8 rises and hangs further downward. Accidents such as hanging have occurred.

This invention aims to eliminate the above-mentioned drawbacks, and its feature is that a ring attached to the end of the operating string is attached to the bottom or side of the cap body attached to the bottom rail of the horizontal blind. A fitting part having a groove into which the ring-shaped connecting body can be fitted is provided, and the ring-shaped connecting body is fitted into the groove of the fitting part somewhat tightly, and the string is fitted into the groove of the fitting part. To provide an attachment for an operation string configured such that when a load greater than the fitting strength of the connecting body is applied to the connecting body, the connecting body comes off from the fitting part of the main body of the cap, thereby preventing accidents. It is.

An embodiment of this invention shown in the drawings will be described in detail below.

The fixture 16a of this invention is as shown in FIG. 2a,
A substantially ladder-shaped projecting portion 19 is formed on the lower surface 18 of the synthetic resin-type cap main body 17, which is formed so that the end of the bottom rail 8 can be inserted therein, and the top portion 20 of this projecting portion will be described later. A connecting groove 21 and a fitting part 22 are provided, in which the connecting body can be compressed and can swing after being press-fitted, and the opening is slightly smaller than the plate thickness or diameter of the connecting body and the inside is larger than the plate thickness or diameter. , a connecting body 23a obtained by bending a metal wire into a mouth shape is attached to the operating string 12, and this connecting body 23a is attached to the operating string 12.
As shown in FIG. 2, it can be press-fitted into the coupling groove 21 of the fitting part 22 through the opening and connected.

Figures 3a and 3l) show another embodiment of the fixture of this invention, and this fixture 16b is attached to the side of the cap main body 17 made of synthetic resin, similar to the above, with a thickness greater than that of the connecting body to be described later. A fitting plate 25 is attached to both ends of a slightly narrow groove and has a coupling groove 24 in the form of a button hole, which is continuous with the groove and has a circular hole large enough for the frame of the connecting body to be inscribed therein. A connecting body 23b is attached to the string 12, which has a hole of a similar shape formed in the center of a synthetic resin-type approximately rectangular plate-like member that is slightly thicker than the groove described above to form a mouth-shaped frame. Connector 23
As shown in Figure 3, b can be inserted and connected from one end into the coupling groove 24 of the fitting plate 25.

The fixture of this invention has the above configuration.
Figure 4 a shows the configuration of a horizontal blind using one of the devices of this invention, the fixture shown in Figures 2 a and 1).
, l).

The configuration of the parts in the figure with the same reference numerals as in Figure 1 is the same as in Figure 1.
The components are the same as those explained in the figure.

The operating string 12 is fitted into the coupling groove 21 of the fixture 16a, which has a connection 23a attached to its hanging end, to such an extent that it will not come off in normal use, but will come off when a rather large load is applied. Since the blind operation is as described above, it will not come off.

FIG. 4a shows the blind hanging down, and in this case, the operating string 12 is wound around the drum 6 in the upper body 1 and is suspended downward by the length of the tilting rope 7 through the upper body 1. Therefore, there is no degree of freedom for the loop portion 26 in the extra length, but when the blind is pulled up as shown in Figure 4, there is room for movement in the loop portion 26 as in the conventional blind, but this loop portion Even if an infant or the like gets their hand caught in the connector 26 or, in the worst case, their neck, the connector 23 will not come off from the coupling groove 21 of the fitting part 22 under normal usage conditions due to the above structure, but will come off when a somewhat large load is applied. Since it is fitted to a certain degree, it can be ensured that it will not come off immediately due to the weight of the infant.

As mentioned above, this invention has a fitting part on the bottom or side surface of the cap body attached to the bottom rail of the horizontal blind, which has a groove into which the ring-shaped connecting body attached to the end of the operating string can be fitted. and the ring-shaped connecting body is fitted into the groove of the fitting part somewhat tightly, and when a load is applied to the string that is larger than the fitting strength of the connecting body to the groove of the fitting part, the ring-shaped connecting body is fitted into the groove of the fitting part. Since the connecting body is configured to come off from the fitting part of the main body of the cap, there is no problem with normal blind operation, but if unnecessary load is applied to the operating string, the connecting body will come off from the fitting part or the fitting plate. Accidents can be prevented by eliminating the loop formed by the detachable string, and even if it comes off in such a state, it can be reattached, and the structure is simple.
