Das übergeordnete Patent 1 072 790 betrifft eine Klinkensperre für in einem senkrechten Rohr od. dgl. bewegte Lastträger, und ist dadurch gekennzeichnet, daß der Lastträger mit winkelförmigen Sperrklinken und das Rohr an den Sperrstellen mit zwei, eine Ringrippe bildenden Ringnuten versehen ist. Werden die Sperrklinken f-förmig ausgebildet, so sind drei zwei Ringrippen bildende Ringnuten erforderlich. Durch diese Vorrichtungen ist es möglich, die Last an den gewünschten, mit Sperrnuten versehenen Stellen gegen ungewolltes Absinken zu sichern, wobei sowohl das Einrasten als auch das Lösen der Sperre durch die Bewegung des Lastträgers erfolgt und dabei lediglich das Eigengewicht der Sperrklinken ausgenutzt wird.The parent patent 1 072 790 relates to a ratchet lock for od in a vertical tube. moving load carrier, and is characterized in that the load carrier with angular pawls and the tube is provided with two annular grooves forming an annular rib at the locking points. Will the F-shaped pawls, three ring grooves forming two ring ribs are required. By With these devices it is possible to place the load at the desired points provided with locking grooves to secure against unintentional lowering, whereby both the engaging and the loosening of the lock through the movement of the load carrier takes place using only the dead weight of the pawls will.

Nach der vorliegenden Erfindung ist der Lastträger mit trapezförmigen Sperrklinken und das Rohr an den Sperrstellen mit zwei eine Ringrippe bildenden Ringnuten sowie einem auf der Ringrippe angeordneten Ringwulst versehen. Die Nuten und der Wulst können nicht nur als Ringe ausgebildet, sondern auch nur an den den Sperrklinken gegenüberliegenden Stellen in das Rohr eingearbeitet sein. Ferner kann der axiale Abstand zwischen den Nuten und der Rippe beliebig gewählt werden.According to the present invention, the load carrier with trapezoidal pawls and the tube to the Locking points with two annular grooves forming an annular rib and one arranged on the annular rib Ring bead provided. The grooves and the bead can not only be designed as rings, but also only on be incorporated into the tube at the points opposite the pawls. Furthermore, the axial Any distance between the grooves and the rib can be selected.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Es zeigenAn exemplary embodiment of the invention is shown in the drawing. Show it

Fig. 1 und 2 verschiedene Arbeitsstellungen der Sperrvorrichtung.Fig. 1 and 2 different working positions of the locking device.

Die Last liegt auf einem nicht dargestellten Lastträger (Platte), der in einem Rohr od. dgl. mit Hilfe bekannter Mittel, z. B. durch eine Kolbenstange, gehoben und gesenkt wird. Der Lastträger weist eine oder mehrere trapezförmige Sperrklinken 21 auf, die in der Nähe des einen stumpfen Winkels 23 mittels einer Achse 24 am Lastträger schwenkbar gelagert sind. Das feststehende Rohr 26 ist mit zwei Ringnuten 27, 28, einer zwischen diesen Nuten angeordneten Ringrippe und mit einem auf der Ringrippe angeordneten Ringwulst 29 versehen. ·The load rests on a load carrier (plate), not shown, which is in a tube or the like. With the help known means, e.g. B. is raised and lowered by a piston rod. The load carrier has a or several trapezoidal pawls 21, which in the vicinity of an obtuse angle 23 means an axis 24 are pivotably mounted on the load carrier. The fixed tube 26 has two annular grooves 27, 28, an annular rib arranged between these grooves and with one arranged on the annular rib Annular bead 29 is provided. ·

Wird der Lastträger in Richtung des Pfeiles F bewegt, so gleiten zunächst die Sperrklinken 21 mit ihrer Nase 22 an der Wand des Rohres. Steht der Lastträger in Höhe der Ringnut 27., so schwenkt die Nase 22 der Klinke 21 infolge der gewählten Drehpunktlage in die Ringnut 27 hinein (Stellung a). Beim weiteren Anheben stößt nun die Nase 22 von unten an den Ringwulst 29, wodurch die Klinke 21 entgegen dem Uhrzeigersinn gedreht wird (Fig. 1 Stellung b), bis sie schließlich die Stellung c erreicht. Wird von hier aus der Lastträger wieder abgesenkt, so stößt die Nase 22 von oben gegen den Ringwulst 29 (Lage d). Somit ist also der Lastträger gegen Absinken gesichert. If the load carrier is moved in the direction of arrow F , the pawls 21 first slide with their nose 22 on the wall of the pipe. If the load carrier is at the level of the annular groove 27., the nose 22 of the pawl 21 pivots into the annular groove 27 as a result of the selected pivot point position (position a). During further lifting, the nose 22 now strikes the annular bead 29 from below, whereby the pawl 21 is rotated counterclockwise (FIG. 1 position b) until it finally reaches position c. If the load carrier is lowered again from here, the nose 22 strikes against the annular bead 29 from above (position d). Thus, the load carrier is secured against sinking.

Soll nun die Last wieder abgesenkt werden, so wird der Lastträger zunächst so weit angehoben, bis er in Höhe der Ringnut 28 steht. Dabei nehmen die Sperrklinken die Stellung e (Fig. 2) ein. Von hier aus kann nun die Last abgesenkt werden, ohne daß ein Sperren eintritt. Die Nase 22 der Sperrklinken gleitet dabei an dem Ringwulst29 vorbei (Stellung/, g, α in Fig. 2).If the load is to be lowered again, the load carrier is first raised until it is level with the annular groove 28. The pawls take position e (Fig. 2). From here, the load can now be lowered without locking. The nose 22 of the pawls slides past the annular bead 29 (position /, g, α in FIG. 2).

Soll der Lastträger durchgehend gehoben oder gesenkt werden, so kommt der Ringwulst (Sperrippe) 29 nicht zur Wirkung. Ein Sperren tritt nur dann ein, wenn der Lastträger beim Anheben etwas über dem Ringwulst 29 angehalten und dann wieder abgesenkt wird, oder wenn beim Senken der Lastträger in Höhe der Ringnut 27 angehalten, dann etwas über den Ringwulst 29 angehoben und schließlich um die zum Sperren notwendige Höhendifferenz wieder abgesenkt wird.If the load carrier is to be raised or lowered continuously, the annular bead (locking rib) comes into play. 29 does not have any effect. A lock only occurs when the load carrier is slightly over the Annular bead 29 is stopped and then lowered again, or when lowering the load carrier in height the annular groove 27 stopped, then slightly raised over the annular bead 29 and finally to the Lock necessary height difference is reduced again.
