The object of the present invention is a fixed frame having a predetermined length fixed to an upper portion of the window, a housing portion coupled to be installed in pairs on both sides of the fixed frame, and a plurality of blind wings installed on the lower portion of the housing portion and rotated up and down A blind having a pair of support straps for supporting each of the blind blades in a rotatable manner, and an opening and closing adjustment strap connected through the blind blades to open and close the respective blades in the vertical direction. The opening and closing rotary bar which is rotated by receiving power from the driving motor is supported by the housing part; Both sides of the opening and closing rotary bar are coupled to each of the winding portion wound the opening and closing control straps; One end of the opening and closing rotary bar is provided with an angle adjusting unit for adjusting the angle of the blind blade using the rotational force; it can be achieved through the electric blind device.

Hereinafter, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First, referring to the configuration of the electric blind according to the present embodiment, as shown in FIG. 1, the fixing frame 1 is fixed to the upper wall of the window by a fixing member such as a screw, and both side ends of the fixing frame 1 are fixed. The housing parts 2 are assembled to each other, and the position thereof is fixed. The winding parts 4 are assembled to the housing part 2 by screwing, as shown in FIG. The winding part 4 is supported by the housing part 2 so that the horizontal movement can be made by reversing mutual directions, and the opening and closing rotary bar 3 receiving the rotational force from the driving motor 9 is Both ends are coupled to and supported by the winding part 4 to transmit the rotational force.

At this time, a plurality of protrusions 4a are protruded at regular intervals in the longitudinal direction on the inner circumferential surface of the winding portion 4, and the coupling grooves 3a are formed on the outer circumferential surface of the opening and closing rotary bar 3 corresponding thereto. It is possible to transmit the power of rotation.

In addition, the winding portion 4 is wound in the form shown in Figure 2b opening and closing adjustment straps 6 for opening and closing the blind blades 5 up and down, the opening and closing adjustment straps 6 are each blind blade ( 5) penetrating, the blind blade (5) is supported so that the angle can be adjusted by a pair of support straps (7), the support straps (7) fixed at regular intervals (not shown) Due to this connection, each of the blind blades 5 can maintain a constant interval.

On the other hand, as the angle adjusting means 10 for adjusting the angle of the blind blade (5), one end of the rotating rod (3) for opening and closing is coupled to the rotating shaft (11) in the axial direction, the first rotating cam ( 12, the rotation is freely mounted, the link 14 is connected to transfer the rotational force of the first rotational cam 12 to the lower second rotational cam 13, the second rotational cam ( The camshaft 13a of 13 is couple | bonded so that the rotational force may be transmitted to the uppermost blade | wing 5 'of the blind blade | wing 5.

As shown in FIG. 4, two protruding screws 12a are fastened to both sides of the first pivoting cam 12, and coil springs constituting engaging portions 11 ′ are formed at both ends on the pivoting shaft 11. This winding allows the forward and reverse rotational force of the rotational shaft 11 to be transmitted to the first rotational cam 12, and a stopper 2a for limiting the rotational angle of the rotational shaft 11 by 180 degrees is provided with a housing. It protruded and fixed to the part 2.

In the figure, reference numeral 15 denotes a support bracket for supporting the camshaft 13a.

It looks at the operation and effect of the present invention electric blinds that constitute such a configuration.

First, when a user receives a power signal using a remote controller or a power switch, the driving motor 9 is operated so that the rotating rod 3 starts forward rotation, and thus is screwed into the housing part 2. Both winding portions 4 are rotated together, and the opening and closing adjustment strap 6 wound thereon is gradually released.

In this rotation operation, the housing part 2 is fixed in position while the winding part 4 is gradually moved horizontally to one side, so that the opening and closing adjustment strap 6 is formed on the outer peripheral surface of the winding part 4. Therefore, even if it is wound in a predetermined width section can be seen that the unwinding or winding position can be always maintained the same, so that the problem that the opening and closing adjustment strap 6 is tangled during operation can be prevented.

When the opening and closing adjustment strap 6 is released in this way, each blind blade 5 is sequentially installed, thereby forming a form that covers the window as shown in FIGS. 1 and 5A.

And, if you want to open the window that was covered, when the rotating rod (3) is reversed by applying the opposite signal to the drive motor (9) winding unit (4) is also rotated in the opposite direction, opening and closing adjustment strap (6) It is gradually wound up, and thus the blind blades 5 are raised while being sequentially stacked from the lower end as shown in FIG. 5B.

In particular, during the winding operation of the opening and closing adjustment strap 6, the take-up part 4 is rotated in a state of being screwed to the housing part 2 is gradually moved in the horizontal direction opposite to the release operation, thereby Opening and closing adjustment strap 6 is to be wound uniformly on the outer peripheral surface of the winding (4).

On the other hand, the electric blind of the present invention can be adjusted by the rotational force of the rotating rod 3, the angle of the blade blade 5 will be described with reference to Figure 3 and FIG.

That is, when the rotating rod 3 is initially rotated by the operation of the drive motor 9, the rotational force is transmitted to the rotation shaft 11 and then the engaging portion 11 of the coil spring wound on the rotation shaft 11. ') Pushes the protruding screw 12a protruding from the first pivoting cam 12, so that the rotational force can be transmitted to the first pivoting cam 12. At this time, the rotation of the locking portion (11 ') is limited by the stopper (2a) it can be seen that the rotation angle of the rotating shaft (11) does not escape 180 degrees.

Then, the rotational force of the first rotational cam 12 is transmitted to the second rotational cam 13 through the connecting link 14, thereby the cam shaft 13a of the second rotational cam 13 is rotated together And converts the angle of the top blade blade 5 '.

Accordingly, each of the blade blades 5 leading to the bottom can be adjusted at the same angle by the action of the support straps 7, when the blade blades 5 are lowered to maintain the angle as shown in Figure 5a On the rise, the opposite angle is maintained as in FIG. 5A.

In particular, the rotation of the rotating shaft 11 which is rotated together with the rotating rod 3 in the above, even if the rotation bar 3 is limited by the stopper 2a within a predetermined angle range while the rotating rod 3 is continuously rotated, the winding portion (4) is rotated so that the opening and closing adjustment strap (6) can continue the winding or loosening operation.

Therefore, it can be seen that only the initial rotational force of the rotating rod 3 acts on the angle adjustment of the blade vanes 5, and the subsequent rotational force affects only the opening and closing of the blade vanes 5.

In addition, although specific embodiments of the present invention have been described and illustrated above, it is obvious that the blind opening and closing structure of the present invention may be variously modified and implemented by those skilled in the art.

However, such modified embodiments should not be individually understood from the technical spirit or prospect of the present invention, and such modified embodiments should fall within the attached utility model registration claims of the present invention.

As described above, the electric blind of the present invention, the operation of the blind is made of the electric movement can be made more effectively the opening and closing operation of the blind by the opening and closing control straps to improve the convenience and reliability of the product. Able to know.

In particular, the present invention can be made with the opening and closing of the blind using a single drive motor, it is possible to achieve a manufacturing cost saving effect through the simplification of the overall structure.
