Abstract

Light and sun protection device comprises an upper rail (A) formed as a closed box with an opening with an operating strand and containing a central operating unit with a blind lock (B) with a double function for a turning and pulling cord and an operating strand with three blind tassels (C1-C3) with a pulling and drawing cord. The lamellae are formed as angled lamellae and are delimited by an end strip. Preferred Features: The blind lock and the operating strand are arranged with the blind tassels on the outer edge of the lamellae.

Description

The The invention relates to a light and sun protection device for doors and Window for in particular horizontally arranged lamellae.

Known are numerous arrangements for the manual operation of light and Sunshades.

at These are several operating cords arranged, not at first glance its function for operation the light and sun protection device can be seen. That is, at Use must be tried, which line is responsible for which function. Furthermore often gets involved in this manual operation an entanglement or knotting the reversing cord with the drawstring done.

By the different operating cords the top rail needs several openings contain or it is to be executed in open construction.

Out The sitter shows that the production and handling the known devices is expensive.

These Devices dust or pollute quickly.

Are known further various forms of slats, z. B. arc, s or z-shaped slats (s. GM 76 00 128 ).

These have little inherent stability and must through suspensions like ladder tape and additional reinforcements be stabilized.

Of the The invention is therefore based on the problem of a light and sun protection device to create that easy to set up and easy to handle manually is.

This Problem is inventively solved a device whose characteristics are reproduced in the protection claim 1.

Further Embodiments are characterized in the subclaims.

According to the invention the light and sun protection device a top rail as closed Box with only one opening for the Operating cords, a central control with a shutter with a double function for the Reversible and drawstring, as well as an operating rope with three blind tassels with continuous tension and reversing cord on.

The Slats of the blind are designed as isosceles angle louvers and are limited by a shutter bar.

The particular advantages of the invention are that there is no intertwining or knotting of the reversing cord with the Pull cord gives more. The handling will be easier.

It there is only one opening left on the shutter box for the operating cords. Thus, by the closed shutter box is a dusting and contamination of the functional elements in the box excluded.

The Design of the slats causes a high intrinsic stability, thereby The device comes out with less suspensions (ladder tape, ladder cord).

Consequently is an almost continuous cleaning, without obstruction by string, the slats possible.

It exists as well the possibility, due to their self-supporting function, ladder tape, ladder cord, Pulling and reversing cord to the outer edges lay the slats.

One embodiment The invention is illustrated in the drawing and will be described below explained.

It demonstrate

1 the frontal view of the device according to the invention.

2 the lateral section of the device according to the invention.

in the closed blind box A is the blinds lock B. This is in double function for the reversible and drawstring executed.

By the exit opening and through the blind tassles C1, C2, C3, the tensile and turning cords are performed.

The Blinds tassels are dependent on the height the blind arranged to each other.

Becomes The tassel C1 is pulled down, turning the lathes led to the left. The tassel C2 automatically moves up.

When the tassel C2 is pulled down, the turns of the slats become right guided and the tassel C1 moves automatically upwards.

The Tassel C3 remains in these operations in consistent position.

Becomes the tassel C3, as the end position of the drawstring, pulled down, the slat surface moves with the end bar upwards. The locking of the slats takes place by a rightward movement of the tassel C3.

The Tassels C1, C2 are not moved by this operation and remain in their position.

The Slats are designed as isosceles angle louvers E and Made of wood and / or metal, the surface being treated is. This can be color or effect material.

The Venetian blind F is designed so that when closed State of the blinds of the shutter box A and the shutter stop bar F form a closed rectangle.
