Description

  The present invention relates to a slat angle adjustment structure for a curtain, and in particular, a winding reel for winding a reel tension string is mainly provided in the curtain mechanism part, and a plurality of reels disposed below the curtain mechanism part by the tension string. A friction wheel is provided at one end of the take-up reel so that the upper end of a suspension line for holding the slat in a parallel horizontal state is wound around the slat. The present invention relates to a slat angle adjustment structure for a curtain in which the angle of each slat is changed by pulling a wire in a rotation direction when the take-up reel rotates.

  Since the curtain is an awning, it not only requires a structure to adjust the shade area by lifting control, but also has a slat angle adjustment function to adjust the indoor light and satisfy the user's indoor lighting demand Must.

  In the conventional curtain, the elevation control structure and the slat angle control structure are mainly incorporated in the control design. After the slat is moved up and down to a desired position, the slat angle control structure is operated to adjust the tilt angle of the slat. Thus, the intensity of the light beam radiated into the room from the outside is determined, and the dual purpose of awning and daylighting is realized. However, in the conventional design, since the elevation control structure and the slat angle control structure are separately designed, it is not only necessary to form them separately in manufacturing, but also an extra process is required during assembly. As a result, the cost becomes high and it cannot be said that it is practical.

  In the present invention, a take-up reel for winding a tension string connected to a reel is mainly provided in the curtain mechanism part, and a plurality of slats arranged below the curtain mechanism part connected to the tension string are moved up and down. In addition, at one end of the take-up reel, a friction wheel is provided around which the upper end of the suspension line is wound to hold the slat in a parallel and horizontal state. Provided is a curtain slat angle adjustment structure in which the angle of each slat can be changed by following the rotation direction when the take-up reel rotates.

  According to the first aspect of the present invention, the take-up reel for winding the tension string connected to the reel is provided in the curtain mechanism part, and a plurality of slats are moved up and down arranged below the curtain mechanism part connected to the tension string. And at one end of the take-up reel, a friction wheel around which the upper end of the suspension line for holding each slat in a parallel and horizontal state is wound is provided. The angle of the slat can be changed by following the direction of rotation when the take-up reel rotates.

  According to a second aspect of the present invention, in the curtain slat angle adjusting structure according to the first aspect, the lifting / lowering and stopping position of the tension string are controlled by a reel.

  The invention of claim 3 is characterized in that, in the curtain slat angle adjusting structure according to claim 1, the lifting and lowering and stopping position of the tension string are controlled by a manually tensioned string.

  The invention of claim 4 is the curtain slat angle adjustment structure according to any one of claims 1 to 3, wherein the friction wheel and the take-up reel are coaxially installed on the curtain mechanism. Features.

  According to a fifth aspect of the invention, in the curtain slat angle adjusting structure according to any one of the first to third aspects, the friction wheel and the take-up reel are installed in the curtain mechanism portion in a non-coaxial state. Features.

  The invention of claim 6 is the curtain slat angle adjusting structure according to any one of claims 1 to 3, wherein the take-up reel and the friction wheel have the same rotation diameter.

  The invention of claim 7 is characterized in that in the curtain slat angle adjusting structure according to any one of claims 1 to 3, the take-up reel and the friction wheel have different rotation diameters.

  The invention according to claim 8 is the curtain slat angle adjusting structure according to any one of claims 1 to 3, wherein the take-up reel and the friction wheel rotate in the same direction.

  The invention of claim 9 is the curtain slat angle adjusting structure according to any one of claims 1 to 3, wherein the take-up reel and the friction wheel rotate in different directions.

The curtain slat angle adjusting structure according to the present invention has the above-described configuration, thereby obtaining the following effects.
1. The upper end of the suspension line of the slat according to the present invention is wound around the take-up reel, and since the pull string is wound around the take-up reel, when the pull string is pulled, the take-up reel is interlocked, In addition, when the take-up reel rotates, the catenary line is linked to the friction wheel, and the rotation angle of each slut changes. As a result, the angle of the slat is declinated, lifted up and down in the closed state, and when the slat is lifted up and down to a predetermined position and then operated to lift the slat in the reverse direction, the slat angle is reversed. By changing to, the angle of the slat that can satisfy the user's demand can be controlled.
2. In the present invention, since the take-up reel and its friction wheel are installed in the curtain mechanism part, the operation and assembly are simple, the purpose of saving the manufacturing cost can be achieved, and the curtain can be simplified and beautified.

  Hereinafter, with reference to the drawings, the structure of the present invention and the functions and effects thereof will be described in detail by way of examples.

  The present invention is a curtain slat angle adjusting structure, and is mainly provided with a take-up reel 3 for taking up a pull string 21 connected to an electric reel 2 disposed in a curtain mechanism portion 1 of a curtain 10; The lower end portion of the pull cord 21 is fixed to the base material 4a provided below the slat 4, and the plurality of slats 4 disposed below the curtain mechanism portion 1 are moved up and down (refer to FIGS. 1 and 2). Control.

Further, a suspension line having a holding line 5a for holding the slats is provided at one end of the take-up reel 3 so as to hang the slats 4 in the width (front-rear) direction in order to position the slats 4 in a parallel horizontal state. A friction wheel 31 to which an upper end portion of the wire 5 is attached is provided, and the suspension wire 5 is pulled in the rotation direction when the take-up reel 3 rotates in the ascending / descending process of the slat 4. The angle changes.
In this embodiment, the tension string 21 passes through the opening 4b provided in the center of the plane of each slat.

According to the above structure, the take-up reel 3 functions as a guide wheel when the slats 4 are moved up and down by the pull string 21, so that the pull string 21 is pulled and fluctuates together with the rotation of the take-up reel 3.
Note that, as in the modification shown in FIG. 3, the stopping position of the pull string 21 may be controlled by the electric reel 2 or may be the manual pull string 22 by manual operation.
Further, although the friction wheel 31 is integrally provided on the one end side of the take-up reel 3, it is needless to say that the friction wheel 31 may be structured to be interlocked with the take-up reel 3.

  The suspension line 5 wound around the friction wheel 31 also rotates together. However, each slat 4 held by the holding line 5a at the upper portion of the suspension line 5 has the suspension line 5 wound up, and FIG. As can be seen from FIG. 5, the slats rise while rotating at a predetermined angle, and the adjacent slats 4 come into contact with each other to generate a dead point. Therefore, each slat 4 located in the upper part is raised and lowered at an oblique angle while being in a closed state.

  In order to correct such a state, after the position of the slat 4 is raised and lowered to a predetermined position by the user, the rotation direction of the friction wheel 31 is also changed by driving the winding reel 3 so that the rotation direction is reversed. Conversely, the suspension line 5 is interlocked by the rotation of the friction wheel 31, and the angle is changed by the holding line 5 a connected in the width direction of the suspension line 5.

  Such a driving state can be well understood with reference to FIGS. That is, the slats 4 held on the upper part of the catenary wire 5 rise while rotating the catenary wire 5 to a predetermined angle as seen in FIG. 4 and FIG. However, by driving so that the direction of rotation of the take-up reel 3 is reversed, the slat 4 is changed from an inclined state having an inclination angle indicated by a chain line to a horizontal state indicated by a solid line. The raising and lowering of the curtain 10 and the daylighting control are completed by one operation. As a result, it is possible to achieve both the purpose of being easy to operate and assemble, saving manufacturing costs, and realizing simplification and aesthetics of the curtain 10.

  As can be seen from the above-described embodiment, the friction wheel 31 only needs to be rotated in conjunction with the take-up reel 3, and the installation thereof is not necessarily coaxial with the take-up reel 3. Further, the rotational diameter of the take-up reel 3 and the friction wheel 31 is set such that in the above-described embodiment, the rotational diameter of the friction wheel 31 is slightly larger than the rotation diameter of the take-up reel 3, thereby Although a relatively large frictional contact is obtained with the friction wheel 31, it is not always necessary to match the rotation diameters. Further, the rotational directions of the take-up reel 3 and the friction wheel 31 may be opposite to each other (for example, it is possible to connect the take-up reel 3 and the friction wheel 31 via a gear). However, since this technique is a conventional technique, the description thereof is omitted.)
