The driving means 10 is a component for generating a driving force to operate the automatic vertical blind 100 using the raising gear according to an embodiment of the present invention, and may be a motor or the like which is commonly used. At this time, it is preferable to use a motor in which the rotating shaft can be operated in both clockwise and counterclockwise directions. Here, the automatic vertical blind 100 using the lattice according to the embodiment of the present invention may be automatically opened or closed under the control of the control means 60 described below, It is preferable that the cover 40 can be opened and closed. Accordingly, in the present invention, an operation switch 12 connected to the driving means 10 and capable of manually driving the driving means 10 is provided, so that the blind slat 40 can be opened or closed depending on the situation.

The pinion gear 20 is a component that is connected to the drive means 10, that is, is coupled to the motor shaft and rotates according to the drive of the drive means 10. The pinion gear 20 is arranged to be engaged with the raiser- do.

The guide frame 30 has a rod shape and is slidable in the longitudinal direction according to the driving of the drive means 10. The guide frame 30 is a gear having a diameter of the spur gear at the distal end, (32) meshing with the pinion gear so as to convert the rotational motion of the pinion gear into a linear motion. In addition, the guide frame 30 is formed with a slot 34 used for rotating operation so that the blind slat 40 described below is opened and closed. The elongated holes 34 are formed to be spaced from each other along the longitudinal direction of the guide frame 30, and are formed diagonally with respect to the longitudinal direction of the guide frame 30 as shown in the drawing. In addition, the long hole 34 may be formed in a semicircular shape. Meanwhile, it is preferable that the stopper S is provided to stop the guide frame 30 when it is moved by a predetermined distance when the guide frame 30 is slid. To this end, the stopper S is disposed apart from both ends of the guide frame, and may be made of rubber, synthetic resin, or the like so as to protect the guide frame 30.

A plurality of blind slats 40 are disposed between the window frames 200 and connected to the guide frame 30 to rotate and open according to the operation of the guide frame 30. [ The blind slat 40 comprises a body 42 and a projection 44, a connecting pin 46, and a shaft pin 48. The body 42 is a part forming the majority of the blind slat 40 and may vary in length, width, thickness, etc. according to the size and shape of the window frame 200. The protruding portion 44 is a portion protruding from the distal end of the body 42 and has a shape of "A" so that the connecting pin 46 described below can be smoothly connected to the guide frame 30 . One of the connection pins 46 is coupled to the protrusion 44 and the other is inserted into any one of a plurality of slots 34 formed in the guide frame 30 to connect the protrusion 44 and the guide frame 30 . The shaft pin 48 constitutes a rotation axis through which the body 42 rotates and is a portion connecting the window frame 200 and the body 42.

The sensing means 50 is provided outside the window frame 200 to sense the amount of light, and may be a commonly used light sensing sensor (CDS).

The control means 60 is a component for controlling whether the driving means 10 is driven according to the amount of light sensed through the sensing means 50. [ The control means 60 controls the illuminating body 62, for example, the LED bulb, which is provided separately, so as to allow the user to know whether the blind slat 40 is opened or closed or whether the driving means 10 is driven . For example, when the blind slat 40 is closed, the LED bulb having a red color is turned on, and when the blind slat 40 is open, the LED bulb having a blue color is turned on.

Hereinafter, an automatic vertical blind using a lattice according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIGS. 5 (a) and 5 (b) and 6 (a) and 6 (b) are views showing the use of an automatic vertical blind using a razor blade according to an embodiment of the present invention, Fig. 8 is a circuit diagram showing an example of an automatic vertical blind using a lattice word according to an embodiment; Fig.

5 (a) and 6 (a) are views showing a state in which the guide frame 30 and the blind slat 40 are rotated in a state where the automatic vertical blind 100 using the razor- And FIGS. 5B and 6B show a state in which the states of FIG. 5A and FIG. 6A are viewed from the outdoor side.

In FIGS. 5A and 5B, the blind slats 40 are open, and sunlight shines through the windows.

At this time, when the amount of sunlight sensed through the sensing means 50 is large, the control means 60 drives the driving means 10 to close the blind slat 40. Of course, depending on the situation, the user may operate the operation means 10 by operating the operation switch 12, and the drive means 10 may be directly driven by the operation of the operation switch 12, The driving means 10 may be driven through the driving means 60.

When the driving means 10 is driven as described above, the pinion gear 20 rotates as shown in FIG. 6A, and a guide frame (not shown) having the pinion gear 32 engaged with the pinion gear 20 30 are operated in a sliding direction in the longitudinal direction, that is, in the right direction in the drawing.

The connection pin 46 inserted in the long hole 34 of the guide frame 30 is also positioned in the left direction in the drawing as shown in Fig. 5 (a), and the direction in which the guide frame 30 moves The blind slat 40 is rotated with the shaft pin 48 as a rotation axis. At this time, since the long hole 34 is formed in an oblique direction with respect to the longitudinal direction of the guide frame 30, the connecting pin 46 can move smoothly, and the blind slat 40 can rotate. As described above, it is preferable that the long hole 34 is formed in a shape that allows the connecting pin 46 to move smoothly while the blind slat 40 is rotatable. In addition to the long hole 34 formed in the diagonal direction as described above, A long hole 34 may be formed and used.

As the guide frame 30 moves, the blind slat 40 is rotated in the closing direction. When the guide frame 30 moves as far as the blind slat 40 is completely closed, The movement of the frame 30 is stopped and the blind slat 40 is closed as shown in Figs. 6 (a) and 6 (b), thereby preventing the sunlight from shining through the window.

Conversely, when the blind slat 40 is to be opened, the blind slat 40 is closed as shown in Figs. 6 (a) and 6 (b) The gear 20, the guide frame 30, and the blind slat 40 are operated.

Thus, those skilled in the art will appreciate that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof.

It is therefore to be understood that the embodiments described above are to be considered in all respects as illustrative and not restrictive and the scope of the invention is indicated by the appended claims rather than the foregoing description, It is intended that all changes and modifications derived from the equivalent concept be included within the scope of the present invention.
