Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a vertical blind,
More specifically, the present invention relates to a cord type vertical blind that can open and close and rotate a louver with a single operation means.

[0002]

2. Description of the Related Art A vertical blind having a large number of vertically suspended louvers as a light-shielding member is called a carrier so that it can be moved in a head rail horizontally provided along an upper frame portion such as a window. From the open state of the blinds, which has the louver suspension means and gathers this carrier on one end side in the longitudinal direction of the head rail, to the closed state of the blinds that are aligned almost uniformly over the entire length of the head rail It is necessary to be able to open and close between them and to adjust the dimming state by rotating the louver around the vertical axis when the blind is closed. Is configured. Therefore, the conventional vertical blind includes an opening / closing rod (screw rod) for opening and closing the blind and a rotating rod (tilt rod) for rotating the louver.

[0003]

Since the conventional two operating mechanism of the open / close rod and the rotating rod is complicated, the operating mechanism is complicated, the number of parts is large, the cost is high, and the operation itself is complicated.

Therefore, it is considered desirable to be able to perform the above two operations with one operating mechanism. However, since the movements of the respective mechanisms performed by these operations are different from each other, both operations are performed by one mechanism. It is not easy to implement with.

The present inventor has addressed such a difficult problem and has noticed that the operation of rotating the louver is originally required in a closed state in which the blinds are aligned substantially evenly over the entire length of the head rail. By linking the carrier for suspending the louver housed in the head rail with the orbiting cord installed over substantially the entire length of the head rail, two operations for opening and closing and rotating the louver can be performed. The purpose is to provide a vertical blind that can be executed by one operating mechanism.

[0006]

In order to achieve the above-mentioned object, the inventor of the present invention suspends a large number of louvers by carriers capable of rotating around a vertical central axis, and suspends a large number of these louvers. In a vertical blind provided movably in the long direction in a long head rail, having a pair of linear cord portions arranged in parallel so that the distance in the head rail width direction can approach and separate. And a rotating cord that can be rotated from the outside is installed over substantially the entire length in the head rail, and a pair of rings, for example, rings in which the linear cord portions of the circulating cord are slidably contacted with each of the plurality of carriers. A cord engaging portion of a die is provided so as to be swingable with respect to the carrier body, and the pair of linear cord portions is linked to move in opposite directions. The carrier body is provided so as to rotate about the central axis by the movement in the opposite direction of the mating portion, and one of the cord engaging portions provided on the leading carrier of the plurality of carriers for opening and closing the blind is further provided. One of the pair of linear cords of the circling cord is connected and fixed by tie or the like, and adjacent ones of the plurality of carriers are connected by a string (spacer tape) of a certain length. The vertical blind of the present invention characterized by the above is completed.

[0007]

According to the vertical blind of the present invention, since the cord engaging portion on one side of the leading carrier is fixed to the revolving cord, the revolving cord is continuously rotated in the blind closing direction with the blind open. By doing so, the leading carrier is carried along with the circulating code, and the following carriers are carried sequentially by the spacer tape to the blind closed position. On the contrary, if the orbiting cord is continuously rotated in the blind opening direction from the closed state of the blind, the leading carrier is carried along with this, and the other carriers are pushed by the leading carrier to the position of the blind opened state. .

When the blind is closed,
When the orbiting cord is rotated within a predetermined range, the pair of cord engaging portions of each carrier move in opposite directions in association with the movement of the orbiting cord. By rotating around the vertical axis, rotation of the louver, that is, rotation of adjusting the dimming state is generated, and opening and closing of the blind and adjustment of the dimming state are performed only by rotating one orbiting cord. The operation of can be performed.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be further described with reference to the embodiments shown in the drawings.

In FIG. 1, reference numeral 1 denotes a box-shaped head rail, which is fixed in a long length along an upper frame of a window, for example. As shown in FIG. 2, a carrier traveling rail 1a having L-shaped legs facing inward is extended in the longitudinal direction from the top surface of the head rail 1, and the head 8a of the carrier 8 is used for the carrier traveling. It can be mounted on the rail 1a for traveling. In addition, inside the head rail 1, FIG.
As can be seen from FIG. 5, the orbiting cord 3 is installed over substantially the entire length of the head rail 1, its tip (right side in FIG. 1) is orbited by the guide pulley 6, and its rear end is the guide pulley 5. And is rotated downwards by the cord rail 4 in the operation mechanism storage box 17 extending downward from the head rail 1.

Reference numeral 7 denotes an operating wheel, which is provided coaxially with the code wheel 4 so as to rotate integrally therewith.
From outside to the outside.

The carrier 8 has a hook 15 suspended from a long slit (not shown) provided on the bottom surface of the head rail 1, and the louver 12 is suspended by this hook. A normal louver suspension mechanism using this hook can be used.

The features of this example are the structure of the carrier 8 described with reference to FIGS. 3 to 9, the relationship between the carrier 8 and the orbiting cord 3, and the relationship of linkage.

In the vertical blind of this example, a large number of carriers 8 are constructed by using parts having the same structure,
However, only the leading carrier 80 is different in that it further uses a cord fastening member 13 for fastening the cord for connecting with the circulating cord.

That is, a normal (other than the first) carrier 8
8 and 9, a head 8a and a main body 8b are integrally provided, and the hook 15 is integrally fixed to the lower end of the main body 8b. The main body 8a is provided with a pair of cord guiding rings 9 and 9 serving as cord engaging portions so as to be swingable around an axis perpendicular to the plane of FIG. 9 by vertical pins 10 and 10, respectively. And this ring 9,9
The orbiting cord 3 is inserted into the. Next, the leading carrier 80 is shown in FIGS. 6 and 7, and the basic structure is the same as that of the normal carrier 8 described above, except that one ring 9 passes through the code insertion portion 14 and the cord stopper. It is different in that it is provided with a structure in which it is connected and fixed to the winding cord 3 by 13.

The maximum length of the space between the adjacent carriers 8 and 80 is determined by the connection of the spacer cords 11 as shown in FIGS. 3 to 5.

The operation of the blind of the present embodiment having the above-described structure will be described with reference to FIGS. 3 to 5. First, the operation of the blind (not shown) (the state where all the carriers are moved to the left side of FIG. 1) is started. When the orbiting cord 3 is rotated counterclockwise in FIG. 3 by operating the cord 2, the leading carrier 80 connected to the orbiting cord 3 moves in the rotational movement of the orbiting cord 3 in the posture shown in FIG. Will be taken. When the leading carrier 80 moves to a certain extent from the blind open position, the spacer cords 11 carry the succeeding carriers 8 one by one and start moving.
When 1 is full, it cannot be moved anymore and is stopped.

The state is shown in FIG.

Next, when the operation cord 2 is rotated in the opposite direction, the orbiting cord 3 is rotated in the clockwise direction in FIG. At this time, since the ring 90 on one side of the carrier 80 is provided in a structure in which it is connected and fixed to the circulating cord 3 by the cord stopper 13, it moves along with the circulating cord 3 and also the ring on the opposite side of the carrier 80. 9 and the ring 9 of the other carrier 8 do not have such a connection relationship with the orbiting cord 3, but since they are engaged in a frictional sliding contact relationship to some extent, the orbiting cord 3 also moves. Is taken to and moved. Therefore, since the pair of rings 9 of the carriers 8 and 80 move in the opposite directions, the carrier body 8b is rotated around the vertical axis, and the state of FIG. If this operation is further continued, the carrier 8 further rotates and shifts to the state of FIG. Further, by rotating the orbiting cord 3 in the counterclockwise direction in these figures, the carriers 8 and 80 shift from the state of FIG. 5 to the state of FIG. 4 and further to the state of FIG. By such an operation, the carrier bodies 8b and 80b are rotated, and accordingly, the louver 12 is rotated for the light control.

When the orbiting cord is rotated clockwise from the state shown in FIG. 5, the leading carrier 80 is fixedly connected to the orbiting cord 3 by the cord stopper 13.
Is carried to the left side of the figure, and when the movement progresses to a certain extent, the next carrier 8 is pushed to the left side, and this can be successively opened and closed until the blind is opened.

As described above, in the blind of this example, two different operations of opening and closing the blind and adjusting the dimming by rotating the louver are performed only by rotating the orbiting cord by rotating the operating cord 2. can do.

[0022]

The vertical blind of the present invention opens and closes the blind by simply rotating one orbiting cord.
There is a feature that you can perform the operation of adjusting the dimming state,
There is no need to have the conventional two operating mechanisms for the opening and closing rod and the rotating rod, and the operating mechanism is simple, the number of parts is small, and an inexpensive blind can be provided.

Further, since the operation means can be performed with only one operation cord, there is an effect that the operation itself is easy.
