Description

FIG. five; in fig. 7 shows a section through D - D in FIG. 6; in fig. 8 - view along arrow E on fng. 7

The sunblinds contain shading plates 1 connected to each other and the bottom rail 2 by the suspensions 3; the lifting device has a shaft 4 with coils 5, which bends around the top suspension 3, closed flexible links 6, made in the form of perforated tape, which are connected to the bottom rail 2 and bend around the sprockets 7 and 8 mounted on the shaft 4, and the sprockets 9 and 10 fixed on the opposite side of the opening. The shaft 4 is connected to the drive mechanism 11.

Rollers 12 are mounted on opposite sides of the opening, directly near the sprockets 7-10, to bring together the envelopes of their branches of flexible links 6 to a distance corresponding to the diameter of the fingers 13 placed between them, which are attached to the shading plates 1. ease of installation of flexible connections 6 tension devices 14 are provided.

With a considerable length of shading plates 1, sunblinds are made with an intermediate closed flexible coupling 6, which in this case passes in the openings of the shading plates on both sides of the fingers 15 located in these openings.

By means of a drive mechanism 11, the rotational movement of which is connected to the shaft 4, the shading plates 1 are raised and lowered, and the angle of their rotation is also regulated.

Raising or lowering the shading plates I occurs as a result of upward or downward movement of the bottom rail 2, which is connected to the respective branches of the flexible links 6, whereby its horizontal position is constantly maintained.

When lifting, the bottom rail 2 assembles the shading plates 1 into the bag, while lowering it, the shading plates occupy the working position, ensuring the overlap of the light opening.

When raising and lowering the shading plates 1, the fingers 13 move between the contiguous branches of the flexible links 6, which prevents the shading plates from oscillating.

The shading plates are rotated as a result of the movement of the branches of the suspensions 3 when the envelopes of the coils 5 rotate. At the limiting angle of inclination of the shading plates 1, the suspensions 3 begin to slip along the surface of the coils 5.

Claims (3)

1. Sun-protection blinds for the openings of buildings and structures, including shading plates interconnected by the lower rail and suspenders, envelopes of the rolls, mounted on the shaft of the tilt-and-turn device mounted in the upper part of the aperture, closed flexible links connected to the lower rail and envelope sprockets mounted on the shaft and the opposite side of the opening, and the drive, while the shading plates are made with the fingers mounted to move inside the profile of the guides to prevent oscillations, characterized in that, in order to use closed flexible links as guides to prevent shading plates from vibrating by bringing the closed flexible links close to the distance needed to move the shading plates placed between them, the tilt-turn device made with pairwise fixed supports, for example rollers, interacting with the branches of a closed flexible link. 2. Blinds according to claim 1, characterized in that the closed flexible connections are made in the form of a perforated tape. 3. Blinds popp. 1 and 2, characterized in that, in order to increase the spatial rigidity of the structure with a considerable length of shading plates, the tilt-up device is made with an intermediate closed flexible connection extending in the holes formed in the shading plates on both sides of the fingers, located in these holes. 74 I t: 00 2 Cf ig. / 2 .2 -b 15 F Sh Fig j HEDGEHOG: / l  four W 75 P.
