Description

Die Erfindung bezieht sich auf einen Rollenzug, dessen Rollenträger pendelnd an der Aufhängevorrichtung gelagert ist und mit der Aufhängevorrichtung ein selbsttätiges, durch S Zug am Handseiltrum ausgelöstes Gesperre bildet.The invention relates to a pulley, the pulley carrier swinging on the suspension device is stored and with the suspension device an automatic, by S Pull on the hand rope strand forms a triggered lock.

Erfindungsgemäß ist bei einem derartigen Rollenzug an dem Rollenträger ein an seinem einen Ende am Handseiltrum geführter, an seinem anderen Ende auf ein Bremsglied einwirkender und von dem als Aufhängevorrichtung dienenden Kipphebel beaufschlagter Doppelhebel drehbar gelagert. Dadurch wird gegenüber den bekannten Vorrichtungen dieser Art die Aufhebung der Sperrung erleichtert. According to the invention is such Pulley train on the pulley carrier is guided at one end on the hand rope strand its other end acting on a braking member and from that as a suspension device Serving rocker arm acted upon double lever rotatably mounted. This will compared to the known devices of this type facilitates the lifting of the lock.

Der Erfindungsgegenstand ist in Äusfüh-• rungsbeispielen in den Zeichnungen dargestellt. The subject matter of the invention is shown in exemplary embodiments in the drawings.

Bei dem Rollenzug nach Abb. 1, der für die Segelschiffahrt Verwendung finden soE, ist in dem Block 1 eine Seilrolle 2 drehbar gelagert, über welche das Seil 3 geführt ist. 4 ist eine am Block 1 befestigte Führungsrolle. Der Block 1 ist an dem Aufhängehebel 5 um die Achse 6 drehbar gelagert. Letzterer trägt an seinem vorderen Ende eine Druckrolle 7. Am anderen Ende des Hebels 5 ist ein Auge 8 zur' Aufhängung vorgesehen.In the roller train according to Fig. 1, which is used for sailing ships, a pulley 2 is rotatably mounted in the block 1, over which the rope 3 is guided. 4 is a guide roller attached to the block 1. The block 1 is on the suspension lever 5 rotatably mounted about the axis 6. The latter has one at its front end Pressure roller 7. At the other end of the lever 5, an eye 8 is provided for 'suspension.

Zum Festklemmen des Seiles 3 dient eine Klemmbacke 9, die an einem Hebel 10 befestigt ist. Der Hebel 10 ist um einen Zapfen 11, der am Block 1, befestigt ist, drehbar und durch sein Langloch 12 verschiebbar gelagert. Weiterhin ist am Hebel 10 noch ein Anschlag 13 vorgesehen. Das Seil 3 ist durch eine am Ende des Hebels IO' angebrachte Führungsbuchse 14 geführt, die auch als Rolle ausgebildet sein kann.A clamping jaw 9, which is attached to a lever 10, is used to clamp the rope 3 is. The lever 10 is about a pin 11, which is attached to the block 1, rotatable and mounted displaceably through its elongated hole 12. There is also a stop on the lever 10 13 provided. The rope 3 is through an am Guide bush 14 attached to the end of the lever IO ', which is also designed as a roller can be.

Die Wirkungsweise ist folgende:The mode of action is as follows:

Steht der Teil 15 des Seiles 3 unter der Einwirkung einer Last, so wird der Kipphebel 5 an die Klemmbacke 9 angedrückt und damit das Seil an der Rolle 2 festgeklemmt. Dies beruht darauf, daß die Achsen der RoI- 45-len 2, 4 und des Zapfens 6 außerhalb der Verbindungslinie zwischen dem Schwerpunkt der Last und dem Aüfhängepunkt liegen.Is the part 15 of the rope 3 under the Under the action of a load, the rocker arm 5 is pressed against the clamping jaw 9 and so that the rope is clamped to the pulley 2. This is due to the fact that the axes of the rollers 45 2, 4 and the pin 6 outside the connecting line lie between the center of gravity of the load and the suspension point.

Soll die Klemmung des Seiles aufgehoben werden, so wird auf den Teil 16 des Seiles, der in einem Winkel zu dem Hebel 10 sich befindet, ein Zug ausgeübt, wodurch der Hebel ro in der eingezeichneten Pfeilrichtung einschwenkt und sich um den Zapfen 11- dreht. Dadurch wird die Klemmbacke 9 vom Seil abgehoben und der Kipphebel zurückgedrückt.If the clamping of the rope is to be released, part 16 of the rope is which is at an angle to the lever 10, exerted a pull, causing the lever ro pivots in the direction of the arrow and rotates around the pin 11-. As a result, the clamping jaw 9 is lifted off the rope and the rocker arm is pushed back.

Beim Anpressen der Klemmbacke 9 verschiebt sich diese, in der Zeichnung gesehen, etwas nach rechts. Sie gleitet damit um einen geringen Teil unter der Druckrolle 7 hinweg.When pressing the clamping jaw 9, this shifts, as seen in the drawing, slightly to the right. It thus slides a small part under the pressure roller 7.

Claims

This sliding away is prevented by the stop 13. When a pulling effect is exerted on the part 15 of the rope 3, the rope tends to continue the clamping jaw 9 with itself. This process can now occur when the lever 10 is stored in an elongated hole 12. -. The brake shoe 9 can be arranged adjustably on the lever 10 so that the size of its contact surface with the rope and the type of attack on the rope can be changed and its wear can be compensated for. In the version according to Fig. 2, the brake shoe9 is connected to the rocker arm. It is fixed by screws 18 and 19 and bolts 20 in a support body 17, which is shown on an enlarged scale in FIG. 3 and with the side cheek removed. By adjusting the screws ι.S and 19, which are via an intermediate layer 21 made of resistant material, z. "B. ' Sheet steel on which the brake lining is supported, the radius of the brake shoe can be changed and adapted to the respective rope diameter. ". : -... _ ■; The support body is connected in an articulated manner to the rocker arm 5 and has longitudinal slots 22 into which the pivot pin 23 of the roller 2 engages. The design can also be made in such a way that zbib-Einygriff in the longitudinal slots also has a special, z. B.- eccentric to the RqBe 2 lying pin is used. -: The release lever 24 is mounted in the block 1 so as to be pivotable about the bolt i-i and lies with its sawed-off end 25 under the bolt 26 which the; Rocker arm with the. Support body. 17 connects. The guide of the rope · over the pulley and through! the release lever corresponds to that according to Figvi. - -: The tension of the load causes the rope to be clamped? That the axes of the rollers, 4 and! of the tenon. 6, which are outside the connection line. lie between the center of gravity of the load and its attachment point ·, iit ;. Saeheti saeheti to get in this opening, the bolt 26 acting on the brake shoe 9. The pivot pin of the roller 2 slides in the longitudinal slot 22 of the support body 17. The braking of the cable is canceled by the release lever 24, which is pivoted from the cable end 16 in the direction of the arrow and thereby with its beveled end 25 the rocker arm 5 The clamping jaw 9 lifts off the rope. In the case of the embodiment according to FIG At the other end of the angle lever 41 is a band 42, preferably made of spring steel, which engages with its other end on a pin 43 fixed on the block 1 and carries the brake shoe 44. The release lever 45, which is on the pin 11 sits, with its front, fork-like end engages around the pivot pin 5 '. 46 is a further guide roller for the rope. For the pin of the roller 4, several holes are provided on the block ι so that one can d ie role 4 can be arranged at different points on the block ι. The purpose of this is to adjust the cable clamp so that the angular bend of the cable 16 shown in the drawing at one end of the lever 45 is always present. 'If a pull is exerted on the rope in the indicated arrow direction α, i.e. the rope is put under load, the rope is automatically clamped to the pulley 2: by the fact that the rocker arm 5 rotates around the (axis 6 and thereby the Gejenkzapf en 5 'is moved in the correct direction by the arrow.: This pulls the strap 42 from the angle lever 41 and clamps the brake shoe to the cable. To release the clamp, pull the cable end 16 and move the release lever 45 in the arrow direction. as a result of which it with its fork-like end moves the pivot pin 5 'back in the opposite direction to the indicated arrow direction fr and thus simultaneously pivots the angle lever 41 about the axis 2' in such a way that the brake shoe is lifted.
