Definitions

  • the invention relates to a lock between a rotating frame and a base.
  • Rotating frames are known as pivoting supports on road or rail vehicle undercarriages for holding containers or other attachable and removable loads. Reliable locking of the rotating frame aligned parallel to the chassis is essential for the operational safety of such transports.
  • the generic features are known from EP 0 516 586 A1.
  • each bolt is pivotally mounted in the base frame about a horizontal axis and can be brought manually into its release position by means of a pivoting lever. To swing out the rotating frame, only the bolt on the relevant side has to be released. Its swiveling lever, which also forms a locking element of the bolt, enters the path of movement of the rotating frame and is automatically returned to its original rest position when it is swung out.
  • the bolt is thus brought back into its locking position, in which, however, the pivoting-back pivoting frame, like a freewheel pawl, can still run over it without conflict. Only after the transport position of the rotating frame has been set does the bolt fall behind the rotating frame long beam and secure it. For this purpose, a relative movement between the bolt and its pivot lever must be possible.
  • the invention has for its object to form a lock of the type mentioned in such a way that the rotating frame is automatically locked on both sides after pivoting back into its transport position.
  • FIG. 1 shows a plan view of a rotating frame which is secured with respect to a base frame by means of locks arranged on both sides of its pivot axis,
  • FIG. 2 shows a side view of one of the locks in the rest position
  • FIG. 3 shows another embodiment of a locking device, in which all movable parts are guided in a straight line
  • FIG. 5 shows a variant of the locking according to FIG. 3.
  • a rotating frame 1 which is shown only in sections in its central region and is provided, in particular, for placing and transporting containers, is pivotably mounted about an axis 3 according to FIG. 1 on an only indicated base frame 2. On both sides
  • the axis 3 and with only a slight offset to this in the longitudinal direction of the rotating frame are fasteners 4 and 4 'fastened to the base frame, with which the rotating frame 1 can be fixed with respect to its pivot axis 3 relative to the base frame 2. They can each be brought into a release position independently of one another via release levers 5, 5 '. They each include a bolt 6/6 'and a locking member 7/7', both of which are resiliently biased (springs 7F and 7F ') into a locking position. Optionally, a tension spring 7F (indicated here at lock 4) or a compression spring 7F '(as indicated at lock 4') can be used to pretension the locking members. Each bolt 6 or 6 'corresponds to an abutment 8 or 8' on the rotating frame side.
  • the rotating frame 1 can be pivoted about its axis 3 here in the clockwise direction.
  • the abutment 8 passes or passes over the retracted bolt 6.
  • the bolt 6 'on the other side remains in its locked position while the abutment 8' facing it runs off it.
  • a distinguishing feature of the exemplary embodiment according to the invention compared to known locks is that a component of the pivoting frame pivoting movement in the longitudinal direction of the vehicle is used here to automatically reset the bolt arranged on both sides of the pivoting axis of the pivoting frame, at least in a pre-locking position.
  • essentially the transverse component of the pivoting frame pivoting movement leads to the resetting of the bolt located in the pivoting direction.
  • the desired effect can be achieved by suitable control bodies or edges projecting laterally beyond the rotating frame and advancing when it is pivoted back.
  • the bolt 6 is a sliding bolt which is guided in a straight line in the underframe and is biased into its locking or locking position (here upwards) by a spring 6F which is only indicated.
  • the abutment 8 of the rotating frame 1 lies against the bolt 6, but can run backwards (to the right) therefrom.
  • the abutment 8 there is a recess 9 on the rotating frame 1 with two control bodies or control edges 9R and 9L forming its right and left edges, between which protrudes a cam 7N of the locking member 7 as its actuating lever.
  • the abutment and the recess with the control edges are preferably molded into an extension piece which is fastened to a lateral arm of the rotating frame.
  • the release lever 5 can be pivoted counterclockwise by hand about an axis 5A which is fixed to the frame and takes the bar 6 with it via a drag joint 5G.
  • the latter has a locking lever 6S projecting transversely to its axis of movement, which interacts with a ratchet lever 7K of the associated locking member 7.
  • the position of the locking member 7 relative to the base frame 2 is defined on the one hand by an axle 7A fixed to the base, on which the locking member 7 is attached, on the other hand by the latch lever 7K resting against the axle 5A of the release lever and finally by a tension spring 7F which biases the locking member into its locked position and tries to pivot it clockwise with respect to axis 7A.
  • the locking member 7 On the axis 7A, the locking member 7 is guided by means of an elongated hole, so that it can carry out a superimposed swivel-sliding movement which is essential for the function of the exemplary embodiment to be described below.
  • the stable release position of the bolt 6 is shown solid.
  • the beginning of the pivoting movement of the rotating frame 1 is indicated by an arrow to the left.
  • a dash-dotted intermediate position of the locking member 7 indicates its movement at the transitions of the bolt between the locking and release position.
  • the recess 9 next to the abutment 8 is sufficiently large that it does not hinder the evasive movement of the locking member 7 or the cam 7N necessary for fixing the bolt 6, but - viewed perpendicular to the plane of the drawing - not deep enough to allow the bolt 6 to be immersed .
  • the abutment 8 can now run over the retracted bolt 6 to the left. Shortly thereafter, the right edge of the recess 9 runs as a control edge 9R against the cam 7N of the locking member (dash-double-dotted, beaked position), which is now pivoted again counterclockwise about its axis 7A.
  • the locking lever 6S of the bolt 6 is released by the pawl lever 7K.
  • the locking member 7 is temporarily pivoted further by the control edge 9R.
  • the bolt 6 moves upwards, but cannot fall completely into its locking position because the rotating frame 1 still slides over it.
  • the bolt 6 cannot fall into the recess 9. Only after their right control edge 9R has passed it can its return spring 6F push it completely up again. This means that its locking position is preset.
  • the release lever plays no role in the readjustment of the bolt locking position. However, it offers clearly visible visual feedback on the respective bolt position, because it points upwards when the locking position is reached and downwards when the bolt is locked in the release position.
  • ERSArZBLArr (RULE 26) Spring force swiveled clockwise (double-dashed position). It can be moved so far in the slot against the axis 7A that the control edge 9R of the recess can slide over the cam 7N until it automatically falls back into the recess 9 under the force of the spring 7F acting to the left.
  • the tip of the pawl lever 7K sits on the front side of the locking lever 6S and rolls on it without being able to lock the bolt. It forms the instantaneous pole for the evasive pivoting movement of the locking member made possible by the elongated hole.
  • the basic position of the locking device 4 is restored when the latch 6 has fallen back behind the abutment 8.
  • the abutment 8 On the other side of the rotating frame, the abutment 8 'runs against the bolt 6' at the same time.
  • FIG. 2c shows the behavior of the lock 4 when the rotating frame is pivoted out in the other direction (arrow to the right, counterclockwise in the view according to FIG. 1).
  • the bolt 6 'on the other side is to be brought into the release position in the manner described above, while the bolt 6 now remains in its rest position.
  • the edge of the recess 9 adjacent to the abutment 8 is used as the left control edge 9L. It first pivots the locking member 7 by means of the cam 7N analogously to the movement in FIG. 2b in a clockwise direction, the locking member 7 sliding in the slot against the axis 7A and evading the control edge 9L.
  • the pawl lever 7K is supported on the locking lever 6S of the bolt 6 and in turn forms the instantaneous pole of the evasive movement.
  • the abutment 8 can therefore run practically unhindered from the bolt 6 and pass the cam 7N.
  • FIG. 3 and 4 show another variant of the locking mechanism, in which two independent components are provided for the functions "latching” and “releasing” of the slide bolt 16, namely a locking member 17 and a plunger 10.
  • FIG. 4 shows the moment in which the bolt 16 in the release position is unlocked and begins to return to its locked position.
  • This lock must also be attached to the base frame in a mirror-image version on both sides.
  • the bolt 16 is prestressed into its locking or locking position by means of a spring 16F.
  • the bolt and the corresponding abutment are beveled contact surfaces with respect to the movement path of the bolt, so that the latter can run off the abutment without jamming when it is lowered.
  • An engagement point of the actuating lever is only indicated by an eye or a pin 15, with which the latch 16 is to be brought into its release position, indicated by dash-dotted lines in FIG. 3.
  • a locking lug 16N forms the steep end flank of a (sawtooth) ramp 16R on the side of the bolt 16, which is in contact with the end face of the locking member 17, which is beveled at the same angle. This is slidably guided in a guide 13. It is biased against the bolt 16 in the reverse direction as a push pawl by a return spring 17F.
  • the plunger 10 has remained in its normal position shown. It can be displaced in a straight line against the force of a return spring 10F through the control edges 19L or 19R attached to the rotating frame and connected to one another by counter ramps. In its rest position, it is prevented from sliding up further by a nose 10N. Via a pair of ramps 12, it is normally in sliding contact with the locking member 17, which can be displaced perpendicularly to the guide 11, except during the above-described lowering of the bolt 16.
  • control edges 19R and 19L are offset so far with respect to the abutment 18 - a level lifted out of the drawing plane - that only the plunger 10, but not the bolt 16, can dip into the recess 19 located therebetween.
  • a ramp 18R provided next to the abutment, which also serves only to temporarily lower the ram 10. In Fig. 4 this is evident from the fact that the upper edge of the bolt 16 in the dash-dotted position is against the lower edge of the extension piece AS shifted to the left in relation to FIG. 3 and not against the ramp 18R.
  • control edge 9L or the ramp 18R analogous to the control edge 9L in the first exemplary embodiment, only has the task of always providing the locking position of the bolt 16 when the abutment 18 has run off the bolt when the pivoting frame is pivoted out and in the meantime this has been arbitrarily removed ⁇ was lowered.
  • the plunger 10 is therefore always depressed, regardless of the direction of movement of the control edges 19R, 19L and the rotating frame, when one of them moves or slides over it. This now even prevents the case that after the pivoting frame has been pivoted out, the bolt 16 is again arbitrarily placed in its lowered release position again, because even if the pivoting frame is pivoted back again - from the left - the right one is forced Control edge 9R temporarily moves the plunger downward and releases any locking of the bolt 16. It does not matter that the two control edges are arranged in the immediate vicinity of one another. You can e.g. B.
  • a direct swivel or slide operation can also be provided in order to be able to release the bolt manually at any time. However, this is not shown here.
  • FIG. 5 shows, again in a greatly simplified manner, yet another embodiment variant of a rotating frame lock, in which again the bolt 16, shown here in the release position, locks the rotating frame 1 from its outer sides and a longitudinally displaceably guided one in the base frame Plunger 10 is provided for automatically resetting the locking into the locked position when the rotating frame 1 is pivoted out or swung in.

  • the rotating frame side member is in the transport position between the bolt 16 and the plunger 17.
  • ERSArZBLART (RULE 26) Furthermore, an actuating device for the locking member 17 is also indicated in FIG. 5, with which the latter can be released manually directly from the latching with the bolt 16. It comprises a hand lever 24, shown broken off here, a shaft 25, an eccentric piece 26 and a shoulder 27 which is fixedly connected to the locking member 17 and on which the spring 17F is supported.
  • the plunger 10 can be pressed down against the force of the spring 10F and thereby pivot the rocker arm 21 in a clockwise direction via a driver pin 22. This in turn engages a driver pin 23 on the locking member 17 and pulls it to the right out of engagement with the bolt 16 or with the nose 16N.

Abstract

L'invention concerne un dispositif de verrouillage situé entre un bogie (1) et un châssis (2) par rapport auquel le bogie est monté de manière à pivoter entre une position de transport et au moins une position de transbordement. Afin de maintenir le bogie dans sa position de transport, il est prévu des loquets (16) sur les deux côtés longitudinaux dudit bogie, qui peuvent être débloqués de leur position de verrouillage à l'aide d'un levier de déclenchement, pour passer dans une position de déverrouillage, déterminable à l'aide d'un élément de blocage (7; 17), et dans laquelle seulement un des loquets doit être débloqué pour faire pivoter le bogie par-dessus lui. Selon l'invention, on veille, indépendamment du sens de pivotement du bogie par rapport au châssis, à ce que les deux loquets soient ramenés automatiquement dans leur position de blocage au moment où le bogie pivote vers l'arrière dans sa position de transport, dans la mesure où chaque élément de blocage est actionné de manière forcée par des arêtes de commande (9L, 9R; 19L, 19R) prévues sur le bogie (1), afin de libérer de manière fiable le loquet associé et de le faire revenir dans sa position de verrouillage. Ce dispositif permet d'éviter un pivotement indésirable du bogie, même lorsque les deux loquets ont été amenés en position de déverrouillage au moment de son pivotement ou après.
