Gegenstand der vorliegenden Erfindung ist eine Aufzug- und Stellvorrichtung für Brettchenvorhänge, deren Brettchen in bekannter Weise mittels Ketten an einem auf der Aufwickelwalze drehbar gelagerten Träger aufgehängt sind.The subject of the present invention is an elevator and adjusting device for board curtains, their boards in a known manner by means of chains on a support rotatably mounted on the winding roller are hung.

Die Brettchen f des Ladens lagern frei in bekannter Weise auf den Stegen g, die an den Ketten h befestigt sind. Die Ketten sind an um die Aufwickelwalze d mittels kreisförmiger Naben drehbaren halbkreisförmigen Trägern i angebracht, welch letztere sich in Haken k führen. Die Naben des Trägers i weisen Ausschnitte / auf, in welche in der Walze d drehbar gelagerte Riegel m bei herabgelassenem Vorhang einfallen und derart die Feststellung der Träger i auf der Walze und hiermit des Brettchenladens in der . in Fig. ι dargestellten Lage herbeiführen. Irr dieser Lage ist das Band e entlastet, der Laden hängt am Träger i. Soll nun ein Hochziehen des Ladens geschehen, so ziehtThe boards f of the store are freely stored in a known manner on the webs g, which are attached to the chains h . The chains are attached to semicircular supports i which can be rotated around the winding roller d by means of circular hubs, the latter being guided in hooks k . The hubs of the carrier i have cutouts / into which bolts m rotatably mounted in the roller d fall when the curtain is lowered and thus the fixation of the carrier i on the roller and thus the board drawer in the. bring about the situation shown in Fig. ι. In this situation, the belt e is relieved, the drawer hangs on the carrier i. If the shop is now to be pulled up, pull

Claims

Patent claim:

Device for pulling up and placing board curtains, their boards are suspended by chains on supports rotatably mounted on the roller, by means of a single string or chain, thereby

after releasing the lock α (Fig. 2) which usually holds the elevator chain in the direction of the arrow on the chain half b. Here, the shop will first take the position shown in Fig. 4, the boards are initially set at an angle. In this position the release of the carrier i from the roller d begins, caused by the action of a linkage 0 which is rotatably mounted on the ceiling of the frame η and which has rigid branches ρ and q . As FIG. 4 shows, the junction ρ lies in front of the bolt m and the stop r located on the carrier i lies at the junction q. If one continues to pull on the chain b, the stops r of the girders will press against the branches q of the rod, whereupon the branches ρ push the bolts m into the roller d . The coupling of the carrier i to the roller d is released and the former fall back into the position indicated in FIG. As the roller d continues to rotate, the tape e is wound up and the curtain is drawn up. If the latter has happened, the chain b and with it the store are fixed by means of the pawl α. If the latter is triggered again, the load falls into the position of FIG. 1 due to its own weight.

characterized in that the girders (i) are coupled to the winding roller (d) by bolts (m) rotatably mounted in recesses (s) of the latter when the curtain is lowered, so that the boards (f) are set at an angle by means of the winding chain (b) can, while rotating the roller for the purpose of pulling up the curtain, the bolt by a linkage (ο ρ q) are released from engagement with the carriers and release the roller for further rotation.
