Definitions
- the present invention is a slat blind according to the preamble of patent claim 1.
- Such lamellanstores are known for example as all-metal stores.
- the lifting and lowering of the slats takes place in conventional slatted blinds by means of an elevator belt or a roller chain, which can be manual or motor-driven.
- the sinking is done by gravity or chain drive.
- a positioning and pivoting of the slats is possible by means of foldable spacers, pantographs and rope elements.
- a generic slat blind is in FR-A-1475733 disclosed.
- the drive device has in a lateral guide rail on each two an upper hub and a lower hub circulating chains, which are arranged in a plane next to each other and parallel to each other.
- On each of the upper hubs is rotatably mounted in each case a drive plate, which each have a semicircular recess.
- the lamellae are provided with lamella carriers arranged on the end side and are mounted in a lamella bearing arranged above the chains until they are individually grasped by the lamella carriers of the opposite, semicircular recesses of the two counter-driven drive plates and transferred to the chains.
- a pinion is rotatably mounted on each disk carrier. By this pinion, the blade is lifted or lowered in opposite drive of the hubs and at gleichièreem drive the hubs it is pivoted or inclined.
- EP-A-890 703 discloses a Venetian blind with fins, in which a rod-shaped plate carrier is guided over a first nut-like slide laterally in a guide rail.
- the slats hang on rope elements on the rod-shaped plate carrier.
- the disk carrier is laterally connected via a lever mechanism with a second nut-like slide, which is guided in the same or another, relative to the first guide rail stationary guide rail. Due to the rope elements, the displacement position and its pivotal position of the slats depends exclusively on the displacement position and the pivotal position of the rod-shaped plate carrier.
- a pivoting of the rod-shaped disk carrier about a pivot axis takes place in that the first slider is displaced relative to the second slider.
- the object of the present invention is to provide a lamellar store which overcomes the above-mentioned disadvantages of the lamellar blinds known from the prior art.
- the object is achieved according to the invention in that, for closing the store, the lamellae are removed individually with the aid of the lamella carriers from a lamella stack arranged in an upper or lower region and guided downwards or upwards.
- the slat blind 1 shown in the figures has a slat stack 7 formed from a plurality of horizontal slats 2.
- Each lamella 2 is according to the end Fig. 3 guided on a plate carriers 3 in lateral guide rails 8.
- the disk carrier 3 have at their ends in each case a pivot arm 19, which is guided by means of a pin 18 in a vertically extending rail 17.
- FIG. 3 in cross-section C-shaped guide rails 8 each have on the inside a vertically extending slot 16 which is slightly wider than the diameter of the cylindrical part of the plate carrier 3.
- the plate carrier 3 engage at their ends through these slots 16 in the interior 14th one of the two guide rails 8.
- two vertically extending guide walls 15 are arranged, whose distance from each other is slightly larger than the width of the slots sixteenth
- a transport device 12 For the transport of the slats 2, a transport device 12 is provided, which in the embodiment according to the FIGS. 1 and 3 two endless Antriepsorgane 4 and 4 'has. These drive members are each placed at an upper and a lower end about a guide roller 11.
- the guide roller 11 ' is according to FIG. 1 driven by an endless chain 6 or other suitable drive member.
- This drive member 6 is driven by a drive shaft 20, according to FIG. 1 is mounted at the upper end of the two guide rails 8.
- This drive shaft 20 may be driven by a motor not shown here or by hand.
- the two drive members 4 and 4 'are preferably designed as a transport belt and each have a plurality of mutually equally spaced recesses 5, which are open to the outside.
- the two organs 4 and 4 'are according to FIG. 1 arranged parallel to each other so that in a central region 4a two recesses 5 complement each other to form a substantially circular cylindrical recess 5a.
- These recesses 5a are each dimensioned so that they can surround and grip a plate carrier 9.
- FIG. 1 shows drive member 4 'is as mentioned above via the guide roller 11' driven.
- the drive member 4 shown on the right is in the area 4a on the drive member 4 'and is positively and frictionally driven by this.
- the pulleys 11 'and 11 are provided with a gear, not shown here, whereby a synchronous running of the drive members 4 and 4' is guaranteed. If the drive member 4 'driven in a clockwise direction, the drive member 4 is driven in the counterclockwise direction and at the same speed accordingly.
- the recesses 5a thus move in the area 4a from top to bottom. When the drive direction is opposite, the recess 5a and the plate carrier 3 held in it move upwards accordingly.
- FIG. 4b shows the state in which only a blade 2 'was transported by the disk pack 7' down.
- three slats 2 "are already lifted off the disk pack 7" . The process can be continued until all slats of the disk pack 7 are arranged at a distance from one another.
- FIGS. 4a-4c clearly show that the disk set 7 or 7 'or 7 "is always arranged at the upper end of the opening 21.
- the view through the disk set is thus never limited View also essential that the lamellae lifted from the stack by the two drive elements 4 and With partially or completely closed Store 1, the moving lamellae are thus held fast and can not be displaced, so that it is not possible, without destroying, to forcibly open Store 1.
- the transport device 12 is thus burglar resistant.
- the slats 2 are also taken by the drive member 4 and moved down. Again, thus a stacked top 7 is removed at the bottom.
- the slats 2 are each taken in a recess 5 ''.
- the slots 16 of the two guide rails 8 are covered by the drive members 4, 4 '.
- the inventive Store 1 is therefore essentially maintenance-free.
- the slats 2 can be pivoted by lateral displacement of the rails 17 in a conventional manner. This pivoting is possible in any height position of the slats. It is also conceivable, however, a design without rails 17, so that the slats 2 are not pivotable.
- the pivot mechanism may be in this case in a drive frame, not shown here.
- the disk pack is arranged at the top and the slats are transported down. Also conceivable is an embodiment in which the disk set is arranged in a lower region and the slats are transported upwards to close the store. The conveying elements are driven in this case in the opposite direction.
- the in the FIGS. 5 to 7 Slat blind shown has a drive device 31, which has two wheels 22 as conveying member, which are each arranged in a rail 8 and rotatably supported about a horizontal axis A.
- the wheels 22 are driven by a drive pinion 28 via an endless drive member 27, for example, a link chain in the directions of the double arrow 33.
- the slats 2 are connected to one another at the ends of the plate carrier 3 via a folding chain 23.
- This folding chain 23 consists of several members 24 which are connected to each other at joints 25 and 26.
- the joints 26 are free and the joints 25 each sit on a plate carrier third
- the disk carrier 3 are, as mentioned above, each guided displaceably at their ends in a vertical slot 16.
- the wheels 22 each have at their periphery a plurality of teeth 32, according to FIG. 5 engage in the region of a slot 16 such that in each case between two teeth 32 a plate carrier 3 and / or middle or side rollers or cams 30 of the chain links 24 is taken or become.
- the wheels 22 in FIG. 5 in the counterclockwise direction, the slats 2 are transported upwards.
- the arranged over the wheels 22 members 24 are folded into a package P, the complete is as soon as all slats 2 to the in FIG. 4a shown disk pack are conveyed upwards.
- the wheels 22 in FIG. 5 Turned clockwise, the plate carrier 3 are individually taken with the slats 2 and transported down.
- the package P is hereby removed and the links 24 are stretched.
- the slats 2 can be pivoted in any height position by means of rails 17.
- the rails 17 are for this purpose according FIG. 7 horizontally displaced in the directions of the double arrow 29.
- the plate carrier 3 are in this case jointly rotated in each case with the lever 19 about its longitudinal axis. Such pivoting is not mandatory.

Abstract
Description
Gegenstand der vorliegenden Erfindung ist ein Lamellenstore gemäss dem Oberbegriff des Patentanspruchs 1.The present invention is a slat blind according to the preamble of
Derartige lamellanstores sind beispielsweise als Ganzmetallstores bekannt. Das Heben und Senken der Lamellen erfolgt bei herkömmlichen Lamellenstores mittels eines Aufzugsbandes oder einer Rollenkette, die hand- oder motorgetrieben sein können. Das Senken erfolgt durch Schwerkraft oder Kettenantrieb. Ein Positionieren und Schwenken der Lamellen ist mittels faltbaren Distanzgliedern, Pantographen und Seilelementen möglich. Beim Absenken der Store gleitet aufgrund der Antriebsart der gesamte Lamellenstapel nach unten und bildet oben den Behang.Such lamellanstores are known for example as all-metal stores. The lifting and lowering of the slats takes place in conventional slatted blinds by means of an elevator belt or a roller chain, which can be manual or motor-driven. The sinking is done by gravity or chain drive. A positioning and pivoting of the slats is possible by means of foldable spacers, pantographs and rope elements. When the store is lowered, the entire stack of lamellae slides downwards due to the type of drive and forms the curtain at the top.
Die Nachteile der zuvor beschriebenen Ausführungsformen sind zahlreich.
- Beispielsweise ist bei Ganzmetallstoren ein Schwenken der Lamellen erst möglich, wenn sich die vorgegebene Distanz der Lamelle eingestellt hat.
- Die faltbaren Distanzglieder, die die Lamellen auf Abstand halten, sind störanfällig.
- Ein horizontales oder schräges Verschieben der Lamellen ist nur bedingt möglich.
- Eine Hochschiebesicherung der Lamellen ergibt sich nur im Falle eines Zwangsantriebes, oder wenn eine zusätzliche Verriegelung eingebaut ist.
- Ein weiterer grosser Nachteil der Antriebsvorrichtungen des Stands der Technik liegt darin, dass sich das Lamellenpaket bei einer Teilabsenkung des Stores im Sichtbereich befindet und hier klobig und wenig ästhetisch wirkt.
- For example, with all-metal blinds pivoting of the slats is only possible if the predetermined distance of the slats has been set.
- The foldable spacers, which keep the slats at a distance, are susceptible to interference.
- A horizontal or oblique displacement of the slats is only possible to a limited extent.
- A push-up protection of the slats results only in the case of a positive drive, or if an additional lock is installed.
- Another major disadvantage of the drive devices of the prior art is that the disk set is at a partial lowering of the store in the field of view and here clunky and looks little aesthetic.
Eine gattungsgemässer Lamellenstore ist in
Aufgabe der vorliegenden Erfindung ist es, ein Lamellenstore zu schaffen, der die oben genannten Nachteile der aus dem Stand der Technik bekannten Lamellenstoresbeseitigt.The object of the present invention is to provide a lamellar store which overcomes the above-mentioned disadvantages of the lamellar blinds known from the prior art.
Die Aufgabe ist erfindungsgemäss dadurch gelöst, dass zum Schliessen des Stores die Lamellen mit Hilfe der Lamellenträger einzeln aus einem in einem oberen oder unteren Bereich angeordneten Lamellen-Stapel entnommen und nach unten oder oben geführt werden.The object is achieved according to the invention in that, for closing the store, the lamellae are removed individually with the aid of the lamella carriers from a lamella stack arranged in an upper or lower region and guided downwards or upwards.
Vorteile: stabile Führung der Lamellen - exakter Abstand der Lamellen zueinander - Dichtung der Führungsschienen mittels den Antriebsbändern - weniger Gelenke - alle Lamellen sind in jeder Position gesichert.Advantages: stable guiding of the slats - exact spacing of the slats relative to each other - sealing of the guide rails by means of the drive belts - fewer joints - all slats are secured in every position.
