Slat blinds with vertical slats

The present invention relates to a louvre door with vertical slats that can be swiveled about their longitudinal axis, with a spindle and a swivel control shaft.

Ee are lamellar actuators with vertical ones around their longitudinal axis üchwenkoaren lamellae become known, in which the Lt.-mellen are each hung individually on supports, which of their-

since ε supported in a straight-line displaceable in a guide rail are. The shift in .Supports that. among themselves are connected with tapes, takes place through a guide rail parallel spindle shaft, which with a nut thread in the foremost support cooperates in such a way that dierer when the f-spindle shaft rotates along the guide rail is moved, and thereby the oncchliereenden fupports at Closing the blind pulls along with the bands mentioned or, if shifted in the opposite direction, the others Supports in front of you otosst.

The pivoting movement of the slats takes place via a to Spindle shaft parallel swivel control shaft, which has a The slats are untex'ed in each support pans simultaneously and in the same direction.

In this known embodiment, the spindle and the swivel control shaft individually by hand via an endless one Chain and a sprocket driven, with between. a sprocket and its associated shaft, if applicable a translation has been arranged.

This known device has the disadvantage that for Open or close the blind and swivel the slats each chain has to be operated, so that an inexperienced user must always try it out first,

This arrangement of the nut body has the advantage that a pivoting movement of the slats through 180 ° is possible without that during the pivoting movement of the slats a longitudinal shift entry. -

The invention is explained, for example, with the aid of the accompanying schematic drawing. Show it:

Fig. 1 is a plan view of a venetian blind, with parts are omitted

Figures 1 to 4 show a guide rail 1 with symmetrical to its longitudinal axis, on the inside of the legs 2 arranged guides 3? in which auf.Hollen 4 lengthways a plurality of supports 5 are displaceably mounted. A vertical axis 7 is rotatably mounted in each support 5 to which a lamella 6 is attached »The supports 5 each have a cylindrical bore 8 through which

a spindle shaft Io is passed through. Parallel to the bore 8, a bore 9 is arranged in each support 5, through which a pivot control shaft 11 is passed. A nut body 12 is arranged between the foremost and the second foremost lamella 5, which is mounted in the guides 3 by means of rollers 4 in a manner analogous to the supports b. In contrast to the support ^% j , the 'bore 3 of the body 12 is provided with a nut thread corresponding to the spindle shaft Io, so that the body 12 is displaced back and forth in the guides 3 when the spindle shaft Io rotates until it hits a the adjacent supports stoεst and the store, as a result of the connecting straps 13 opens or closes. If the nut body 12 is omitted, the bore 8 of the last magnifying glass 5 is provided with a nut thread corresponding to the Cpindelwelle Io. The pivoting control shaft 11 has longitudinally parallel trains and fields, "which interact with a screw gear, not shown, housed in each support 5, which connects the pivoting control shaft 11 with the axis 7. This causes the slats δ to move about their longitudinal axis when the pivoting control shaft rotates 11, pivoted.

From the preceding explanations, SiCh _{1 shows} that the slat blinds are opened or closed by a rotation of the spindle shaft Io and the slats are pivoted "" by a rotation of the swivel control shaft.

At one end of the guide rail 1 is a transmission housing 14 with centering organs 15 plugged on and rigidly attached to 'excit'bar » In the housing 14, a shaft 16 is rotatably mounted, which is fixed by the connecting body 17 to the spindle shaft Io "is connected" so that the shaft 16 is only an extension of the spindle shaft Io protruding into the housing 14 forms. Brnllel to shaft 16 is in the housing 14 a shaft 18 rotatably mounted, which by, the ver ^ binding body 19 firmly connected to the swivel control shaft 11 is, ώο that the shaft 18 speaks into the housing 14 Extension of the Schwenksteuerwellρ 11 forms. Aul "of the shaft 16 is a bevel gear 2o rotatably arranged, which meshes with a bevel gear 21, which rotatably on a shaft driven by hand or motor

22 seated. Furthermore, a gear wheel is non-rotatably on the yoke 16

23 arranged, which meshes with a tickle 24 running freely on the shaft 18. A body 25 is placed on the shaft 18 such that it can be adjusted and locked. Axially around the shaft Λ ΐδ are arranged between the pinion 24 and the body 25 disc springs 26, the tension of which can be adjusted by moving the body 25. It is obvious to each man to use another elastic body instead of the disc springs.

If the bevel gear 21 is now rotated, the bevel gear 2o the spindle shaft Io with its extension 16 and

the gear 23 rotated. The mother body shifts in the process 12 against one of the neighboring supports 5- The. ;

• Gear 23 rotates the tickle 24 »the one with the springs 26 ..

* and the body 2b forms a friction clutch, so that through the geared connection between the gear 23 and the tickle 24, the spindle shaft Io drives the swivel control shaft 11f. The swivel control shaft 11 swivels over the screw gear (not shown) in the support b the slats 6 until they touch each other. The resistance will tan a continued rotation of the pivot control shaft 11 greater than the frictional force of the

At this moment the mother body 12 reaches the one the neighboring Supports 5, so that the store is open or is closed.

Figures 3 and 4 show the same guide rail 1 as in Figures 1 and 2, in which a spindle lo_and a pivot control shaft 11 is arranged, on which supports 5 are slidably mounted.
