Description

Automatic vertical blind}

The present invention relates to a vertical blind.

Generally, a vertical blind is a device installed in a window of a building to allow for a shade or a certain amount of light. In such a vertical blind, a plurality of band-shaped blind pieces drained in the vertical direction of the window are arranged so that the respective blind pieces are changed in direction and gathered or unfolded to one side edge of the window.

FIG. 1 is a view showing a conventional solar follow-up type vertical blind, and FIG. 2 is a view from the "A" point of the solar follow-up vertical blind shown in FIG.

The conventional sun follower type vertical blind disclosed in the applicant's patent application No. 1378538 includes a plurality of first shafts 1 arranged vertically in the vertical direction and rotating forward and backward as shown in Fig. A second shaft (2) arranged in a direction orthogonal to the first shaft and rotating forward and backward; A mover (3) rotatable in a forward and reverse direction integrally with the second shaft and reciprocating along a longitudinal direction of the second shaft; A support rod (4) extending at an end of the first shaft and perpendicular to the first axis; A slope adjusting drum (6) disposed on the lower side of the support bar and parallel to the support bar, the slope adjusting drum being rotated in the forward and reverse directions; Connecting bands (5) of elastic material interconnecting the outer peripheral surfaces of both ends of the mover and the outer peripheral surfaces of both ends of the tilt adjusting drum; A plurality of blind pieces (7) arranged on the lower side of the inclination adjusting drum in a rectangular plate shape arranged at regular intervals in the vertical direction; A solar reflective sheet formed on each of said blind pieces; And a connecting wire (8) passing through each of the four corners of the blind piece and wound around the slant adjusting drum to interlock with the forward and reverse rotations of the slant adjusting drum to tilt and rotate the plurality of blind pieces.

Particularly, the structure shown in FIG. 2 has a structure in which the mover 3 performs forward and reverse rotation integrally with the second shaft 2, but performs a forward and reverse rotation operation at a fixed position with respect to the first shaft 1. [ 2, the moving piece 33 of the end portion of the rotating piece 32 provided on the mover 3 is inserted into the rotation guide piece 12 of the connecting hole 11 coupled to the first shaft 1, And a mechanism for reciprocating along the mobile slot 12 'formed in the slot.

Therefore, since the driving means such as the driving motor connected to the first shaft 1 and the second shaft 2 can be electrically controlled, the direction of the direct sunlight can be adjusted according to the mechanism for adjusting the inclination angle of the blind piece, It is possible to achieve a cooling effect by blocking direct sunlight, and also direct the direct sunlight to the room in the winter season to achieve a heating effect.

However, in the conventional solar follow-up vertical blind, the moving piece 33 of the end portion of the rotating piece 32 provided on the mover 3 is rotated by the rotation guide piece 12 of the connecting hole 11 coupled to the first shaft 1 , The rotation range of the mover 3 is restricted by the arc-shaped movement slot 12 ', and ultimately the blind piece 7 is rotated by the rotation of the blind piece 7' There is a problem that rotation in the up-and-down direction is limited.

Since the connecting band 5 made of an elastic material has a structure in which the outer circumferential surfaces of both ends of the mover 3 and the outer circumferential surfaces of both ends of the tilt adjusting drum 6 are connected to each other, There is a problem in that the rotational force is not properly transmitted to the blind piece 7 due to the slip on the outer circumferential surfaces of both ends of the slider 3 and the outer circumferential surfaces of both ends of the slant adjusting drum 6. [
