Description

Blind {Blind}

The present invention relates to a blind, and more particularly, to a blind to allow the light shield plate to be rotated by a predetermined angle during lifting, as well as to raise and lower the light shield plate only by the operating rope without a separate rotation lever.

Curtains mounted on a window selectively block light, such as opening and closing a window while moving in a horizontal direction and opening and closing a window while moving in a vertical direction.

The former includes general curtains which are integrally manufactured with curtain cloth, and so-called vertical blinds which are separated by a plurality of curtain cloths along the vertical direction and connected by ropes.

And the latter are known as so-called Roman shades, roll screens and line blinds. Roman shade refers to the bottom curtain cloth being gradually rolled up and rolled upward. The roll screen refers to opening and closing a window by winding or unwinding the curtain cloth on the rotating shaft by rotating the rotating shaft while the one end of the curtain cloth is fixed to the rotatable rotating shaft.

In contrast, the blinds, also called line blinds, have a frame 110 fixed to the ceiling, and a plurality of light shield plates 120 arranged in a horizontal direction parallel to the frame 110, as shown in FIG. And, the connecting line 130 for connecting each light shield plate 120 from the front and rear, the operating rope 140 to move each light shield plate 120 up and down, and each light shield plate 120 in the correct position Rotate in and consists of a rotary lever 150 for opening and closing the light flowing from the window.

Thus, when installed in the window as shown in Figure 7 it can completely shield the light flowing into the window. If the light is to be introduced into the room by pulling the operating rope 140, the angle light shielding plate 120 is fully pushed up to the frame 110, or by rotating the rotary lever 150, each light shielding plate ( 120 may rotate to allow light to pass through.

However, in the case of this general type of blind, as a means for rotating the light shielding plate 120, a separate rotary lever 150 and a corresponding rotating body should be further provided. Therefore, there is a disadvantage that the inconvenience and hassle, such as twisting with the adjacent operating rope 140 during operation, as well as relatively complicated structure.

It is an object of the present invention to provide a blind which allows the light shield plate to be rotated a predetermined angle during lifting, as well as to raise and lower the light shield plate only by the operating rope without a separate rotation lever.

Another object of the present invention is to provide a blind which does not use twisting of the wire while the structure is simple and compact as a whole, so that the blind is manufactured without using the rotary lever and other structures.

Hereinafter, with reference to the accompanying drawings will be described in detail for the subject innovation.

1 to 3 are perspective views showing the operating state of the blind according to the present invention, respectively, Figures 4a, 4b to 6a, 6b is a view for explaining the operation of Figures 1 to 3, respectively.

As shown in these figures, the blind according to the present invention is fixed to the ceiling or the like, but the frame 10 having the opposite side walls (10a, 10b) and the frame 10 in the longitudinal direction of the frame 10 A rotating shaft 12 rotatably disposed along with an operating rope 30 for rotating the rotating shaft 12 in the forward and reverse directions, and a gear body 18 for rotating the rotating shaft 12 when the operating rope 30 is pulled out; And a plurality of light shielding plates arranged in parallel with the frame 10 along the height direction, and the front and rear rows 41 and 42 for controlling the angles of the light shielding plates by supporting the light shielding plates in front and rear, respectively. It is provided on the rotating shaft 12 and includes a plate rotating device 50 (see Figs. 4b, 5b, 6b) to rotate the light shielding plate by a predetermined angle by the pull operation of the operating rope (30).

Referring to the perspective view of Figures 1 to 3, the light shielding plate is integrally supported by one left and right plate connecting line 14 passing through the center. And the plate connecting line 14 is fixed to the rotary shaft 12 in the frame 10 is wound and unwound in the main winding drum 16 to rotate in the forward and reverse direction with the rotary shaft 12.

For reference, when referring to the cutout region of FIG. 1, there is one main winding drum 16 in the frame 10 on the left and right sides thereof, and one auxiliary winding drum 51 adjacent thereto. This is because it is a means for supporting a pair of relatively long light shielding plate 20 on both sides to be given the same reference number considering the same configuration.

Also referring to the cutout region of FIG. 1, separate brackets B are shown in the frame 10 at positions adjacent to the main winding drum 16 and the auxiliary winding drum 51. These brackets B are means for fixing the main winding drum 16 and the auxiliary winding drum 51 in the proper positions in the frame 10 and will not be emphasized.

The plate connecting line 14 is elongated downward while its upper end is wound on the main winding drum 16, and then is fixed to the lowermost light shielding plate 20 through the center of each light shielding plate 20. .

Accordingly, when one side 30a of the operating rope 30 is pulled downward, the rotation shaft 12 rotates in one direction by the gear body 18, and the main winding drum 16 rotates in conjunction with the plate connecting line 14. Is wound around the main winding drum 16 to raise the light shielding plate 20 upwards. On the contrary, when the other side 30a of the operating rope 30 is pulled, the light connecting plates 20 are dropped by their own weight because the plate connecting line 14 wound on the main winding drum 16 is unwound (unwinded). It becomes possible.

This series of operations is a common blind method. However, in the present invention, when one side 30a of the operating rope 30 is pulled downward in the state of FIG. 1, the light shielding plates 20 rotate as shown in FIG. 2 by a predetermined angle. Of course, the light shielding plate 20 is injured by further pulling one side (30a) of the operating rope 30 in the state of FIG. Similarly, when the other side 30a of the operating rope 30 is pulled in the state of FIG. 1, the light shielding plates 20 rotate in the opposite direction as before.

As such, the light shielding plates 20 rotate by a predetermined angle in the original position only by the pulling operation of the operating rope 30, which is made possible by the plate rotating device 50 interacting with the front and rear strings 41 and 42.

Referring to the previous drawings and the drawings of FIGS. 4A, 4B to 6A, 6B, the plate rotating apparatus 50 is largely coupled to the rotating shaft 12 adjacent to the main winding drum 16 to form the rotating shaft 12. ) And a torsion coil spring 52 which is mounted to the mounting winding 51a formed on the auxiliary winding drum 51.

The torsion coil spring 52 has quantum end portions 52a and 52b that are oriented in the original direction after the quantum end portions 52a and 52b are further biased to the opposite side in a conventional circular spring. Therefore, when the adjacent quantum end portions 52a and 52b are pressed in the direction away from each other, the torsion coil spring 52 serves to tighten the auxiliary winding drum 51 from the outside. On the contrary, if the adjacent quantum step portions 52a and 52b are pressed in the direction in which they are spaced apart from each other, the tightening is released.

The upper ends of the front and rear strings 41 and 42 are fixed to the quantum end portions 52a and 52b of the torsion coil spring 52 in the knots 41a and 42a. As described above, the front and rear strings 41 and 42 are positioned at the front and the rear of the light shielding plates 20 to adjust angles of the light shielding plates 20. Therefore, when the height difference of the upper knots 41a and 42a of the front and rear strings 41 and 42 fixed to the quantum end portions 52a and 52b of the torsion coil spring 52 is changed, The predetermined angle can be rotated.

Then, a detailed operation thereof will be described with reference to FIGS. 4A, 4B to 6A, 6B. For convenience of description, FIGS. 4A and 4B correspond to FIG. 1, FIGS. 5A and 5B correspond to FIG. 2, and FIGS. 6A and 6B correspond to FIG. 3.

When the light shielding plates 20 are arranged in a horizontal state as shown in FIG. 1, as illustrated in FIG. 4A, the quantum end portions 52a and 52b and the front and rear strings 41 of the torsion coil spring 52 are formed. The upper knots 41a and 42a of 42 are substantially symmetrical on both sides about the rotation axis 12. In this case, as shown in FIG. 4B, the quantum end portions 52a and 52b of the torsion coil spring 52 are not in contact with either side walls 10a and 10b of the frame 10.

When one side 30a of the operating rope 30 is pulled slightly in this state, the light shielding plates 20 are arranged in a row while rotating a predetermined angle as shown in FIG. 2. That is, since one side 30a of the operation rope 30 is pulled as shown in FIG. 5A, the auxiliary winding drum 51 is rotated while the rotating shaft 12 rotates. Then, the torsion coil spring 52 wound on the outer side of the auxiliary winding drum 51 also rotates a predetermined angle along the auxiliary winding drum 51. At this time, the quantum end portions 52a and 52b of the torsion coil spring 52 are rotated. Any free end 52a is biased toward one wall 10a of the frame 10.

Accordingly, as shown in FIG. 5B, the height difference between the quantum end portions 52a and 52b of the torsion coil spring 52 and the upper knots 41a and 42a of the front and rear strings 41 and 42 are different from each other. That is, the free end of 52a and the knot of 41a are more biased down than the free end of 52b and the knot of 42a. Therefore, since the rear row 42 is loosely maintained at the same position while being biased relative to the front row 41, the light shielding plates 20 can rotate as shown in FIG.

Of course, even if the one side (30a) of the operating rope 30 continues to be pulled downward in the state as shown in Figure 2 one side free end (52a) of the torsion coil spring 52 hits one wall (10a) of the frame 10 Further rotation is blocked. And by the pulling force, the torsion coil spring 52 acts as a force in the direction in which the one free end portion 52a of the torsion coil spring 52 approaches the other free end portion 52b. Constraints are released from the phase and the auxiliary winding drum 51 can idle more smoothly. Of course, if one side 30a of the operation rope 30 continues to be pulled downward, since the main winding drum 16 is rotated, the plate connecting line 14 is wound around the main winding drum 16 while the light shielding plates 20 are formed. It will rise upwards.

Again, in the state of FIG. 1 or 2, when the other side 30b of the operating rope 30 is slightly pulled downward, as shown in FIG. 3, the light shielding plates 20 are rotated in a direction opposite to that of FIG. do.

As shown in FIG. 6A, since the other side 30b of the operating rope 30 is pulled, the auxiliary winding drum 51 is rotated while the rotating shaft 12 rotates in the opposite direction. Then, the torsion coil spring 52 wound on the outer side of the auxiliary winding drum 51 also rotates a predetermined angle along the auxiliary winding drum 51. At this time, the quantum end portions 52a and 52b of the torsion coil spring 52 are rotated. The other free end 52b is biased toward the other wall 10b of the frame 10.

Therefore, as shown in FIG. 6B, the height difference between the quantum end portions 52a and 52b of the torsion coil spring 52 and the upper knots 41a and 42a of the front and rear strings 41 and 42 are different from each other. That is, the free end of 52b and the knot of 42a are more biased down than the free end of 52a and the knot of 41a. Therefore, the light shield plate 20 is able to rotate as shown in Figure 3 because the front row (41) is loosely maintained at the same position while being biased relative to the rear row (42).

Of course, even if the other side 30b of the operating rope 30 continues to be pulled downward in the state as shown in FIG. 3, the other free end 52b of the torsion coil spring 52 hits the other wall 10b of the frame 10. Further rotation is blocked. And by the pulling force, the torsion coil spring 52 acts as a force in the direction in which the other free end 52b of the torsion coil spring 52 approaches the other free end 52a. Constraints are released from the phase and the auxiliary winding drum 51 can idle more smoothly. Of course, if the other side 30b of the operating rope 30 continues to be pulled downward, the light shielding plates 20 are self-weighted because the plate connecting line 14 wound on the main winding drum 16 is unwound (unwinded). It will be able to fall by.

As such, according to the present invention, the light shielding plate 20 may be elevated only by the operating rope 30 without a separate rotation lever, and the light shielding plate 20 may be rotated by a predetermined angle during lifting.

In addition, according to the blinds, the blinds are manufactured without using the rotary lever and other structures thereof, and thus the overall structure is simple and compact, thereby reducing the failure rate and preventing twisting of the wires.

Although the present invention has been described in detail with reference to the drawings, the present invention is not limited thereto.

As described above, according to the blind of the present invention, there is an effect of rotating the light shielding plate at a predetermined angle during lifting, as well as raising and lowering the light shielding plate only by the operating rope without a separate rotation lever.

In addition, according to the blinds, the blinds are manufactured without using the rotary lever and other structures thereof, and thus the overall structure is simple and compact, thereby reducing the failure rate and preventing twisting of the wires.
