Abstract

In a lock between a bogie (1) and a chassis (2) in relation to which the bogie can swivel to and fro between a transport and at least one transfer position, in which bolts (16) are fitted on both longitudinal sides to secure the bogie in its transport position which can be moved from their locking position into a released position determinable by a locking member (7; 17) by means of a release lever (5) in which, however, only one of the bolts need be released to pivot the bogie thereover, according to the invention, it is ensured, independently of the pivoting direction of the bogie in relation to the chassis, that both bolts are automatically taken into their locking position when the bogie is pivoted back into its transport position in that each locking member is necessarily actuated by control edges (9L, 9R; 19L, 19R) on the bogie (1) in such a way that the appropriate bolt is reliably released and returned to its locking position. This prevents unintentional pivoting of the bogie even if both bolts have been set in the released position during or after its pivoting.

Description

Locking between a rotating frame and a base

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. There, 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 bolt on the other side - from which the rotating frame had run off - was not touched by this process. The rotating frame should run against it when it is brought back into its transport position. In the event that this bolt was also inadvertently or improperly brought into the release position, no security is provided in the form of an automatic reset, so that in the worst case the rotating frame can then swing freely to the other side. This also applies to the locking of the same type described in EP 0 325 814 A1.

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.

ERSÄTZBLÄTT (RULE 26) This object is achieved with the features of claim 1. The features of the subclaims indicate advantageous developments of this object.

When the rotating frame is pivoted back, a locking member of the bolt from which the rotating frame had run is inevitably temporarily brought into a release position so that this bolt, which may be held by its locking element, is also returned securely to its locking position preventing the pivoting of the rotating frame. If he is already in this position anyway, the forced actuation of his locking member has no further influence. Preferably, the bolt, over which the rotating frame had been swung out, is inevitably automatically returned to its locking position even if it was again adjusted to the release position after the rotating frame was swung out.

Further details and advantages of the subject matter of the invention will become apparent from the drawing of exemplary embodiments and their detailed description which follows below.

They show in a simplified representation reduced to the essential components

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,

2a to 2d different positions of the elements of this lock to clarify the function,

3 shows another embodiment of a locking device, in which all movable parts are guided in a straight line,

4 shows a shifted position of the locking components shown in FIG. 3,

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

€ RSATZBLÄΓT (RULE 26) 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.

After loosening z. B. the bolt 6, which is then held by its locking member 7 in the release position, as will be shown later, 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. In the prior art, however, essentially the transverse component of the pivoting frame pivoting movement leads to the resetting of the bolt located in the pivoting direction. Even in such a configuration, however, 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 construction and the mode of operation of the locking device 4 will now be discussed in more detail with reference to the side view in FIG. 2. The lock 4 'is constructed in mirror image with an identical mode of operation and is therefore no longer specifically described.

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. In the locked state, the abutment 8 of the rotating frame 1 lies against the bolt 6, but can run backwards (to the right) therefrom. In the vicinity of 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. 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.

With some position sketches (Fig. 2a to 2d), the movement sequences when actuating the lock 4 are illustrated. In these sketches, only the axles 5A and 7A, which are fixed to the frame, are indicated as reference points as well as the rotating frame 1 or the abutment 8, the bolt 6 and the locking member 7 in different positions and states of motion. Simplified, the movements of the rotating frame are indicated here in a straight line; in reality, of course, these are swiveling movements on large radii around axis 3, the component of which is visible here in the longitudinal direction of the underframe.

2a shows the release of the locking mechanism 4 by the release lever 5, which is pivoted downward in the counterclockwise direction.

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 .

REPLACEMENT SHEET <RULE 26) Upon downward manual pressure on the release lever 5, starting from the basic position shown in Fig. 2, the locking lever 6S of the bolt pushes against the pawl lever 7K of the locking member 7 and pivots it against the force of the spring 7F about its axis 7A against the Clockwise. The torque required for this is achieved by the horizontal distance between the free locking lever end and the axis 7A. After the bolt 6 has been lowered sufficiently, the end face of the locking lever 6S sliding over the tip of the latch lever 7K, the latter is pulled behind / above the locking lever 6S by the spring 7F, which is constantly pulling to the left, and locks the bolt in its release position (solid Position in Fig. 2). The latch must carry out a slight overstroke downwards before the latch lever 7K engages, so that a high level of security against inadvertent release and latching of the latch 6 is achieved.

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.

When the rotating frame 1 is pivoted back into its transport position (FIG. 2b; arrow to the right), the right control edge of the recess 9 initially runs against the latch 6 from the other side (here from the left). It slides it downwards on both sides against its return spring 6F and initially holds it in this instable position. The end face of the bolt locking lever 6S now faces the tip of the ratchet lever 7K (drawn solid). Next, the locking member 7 is opposed by the control edge 9R via the cam 7N

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. On the other side of the rotating frame, the abutment 8 'runs against the bolt 6' at the same time.

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). For this purpose, 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.

Upon return of the rotating frame 1 from this pivoting position, which would run clockwise in FIG. 1, the abutment 8 now runs against the cam 7N (arrow to the left) as shown in FIG. 2d and lifts the locking member 7 about its axis 7A so far from that the pawl lever 7K safely releases the locking lever 6S of the bolt 6, regardless of the position in which the bolt 6 is currently. The goal is thus achieved that the bolt 6 is always in its locking basic position when the rotating frame 1 is pivoted back, even if the abutment 8 was not previously pushed over it. Because the lock 4 'on the other side of the rotating frame is constructed in mirror image and is actuated in accordance with the locking 4, the double-sided locking of the rotating frame in the transport position is automatic even when misused or

ERSAHBLÄTT (RULE 26) inadvertent actuation of one of the bolts 6 or 6 'is ensured, regardless of its pivoting direction.

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. In FIG Components of this locking in the normal or locking position, while 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. As in the first exemplary embodiment, the bolt 16 is prestressed into its locking or locking position by means of a spring 16F. Just as in the first exemplary embodiment, 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.

When the bolt 16 is moved downward into its release position, the locking member 17 is temporarily pushed backwards against the spring 17F by the ramp 16R until it can fall back over the locking lug 16N. The latch is thus locked in the release position, and the rotating frame can be pivoted out — over the lowered latch 16.

Until then, 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.

SPARE BLADE (RULE 26) When swiveling the rotating frame - left movement of the attachment AS on the rotating frame, which carries the control body or control edges 19R, 19L and an abutment 18 - the control edge 19R inevitably passes over the tip of the plunger 10 and presses it into the guide 11 below. At the same time, he has to move the locking member 17 in the guide 13 so far to the right via the pair of ramps 12 that the lower left edge thereof is safely lifted out of engagement or latching with the locking lug 16N of the locking bar 16. The pair of ramps 12 could also be represented by a pair of pins and oblique grooves in order to achieve a positive coupling between the locking member 17 and the tappet 10. The moment when the bolt 16 is released from its lowered, locked position is shown in FIG. 4. Under the force of the spring 16F, the bolt 16 can now perform a short idle stroke into an intermediate position, again indicated by dash-dotted lines. Its upper edge runs against the attachment AS from below. The locking position is thus prepared again. However, the locking member 17 can no longer overlap the locking lug 16N even after the tappet 10 is relieved, because it is slightly above the lower edge of the locking member. When the rotating frame is swiveled out completely, the bolt 16 returns to its normal position shown in FIG. 3, its start-up slope 16S formed on the left sliding up along a ramp 20 on the right edge of the attachment piece AS. The 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. The same applies to 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.

When the rotating frame is swiveled back again after swiveling out, the ramp 20 on the right edge of the attachment AS has to press the bolt 16 down over its run-in slope 16S. In the normal case, the latch 16 only reaches the dot-dash intermediate position and is not locked with the locking member 17. If this should happen, or if it had already been done by arbitrary actuation of the release lever, the locking member will definitely be in the manner already described

ERSAΓZBLÄΓΓ (RULE 26> raised again when the ramp 20 or the control edge 9R then passes the plunger 10.

The control edge 9L or the ramp 18R, on the other hand, 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. also provide a control edge on both inner sides of the long girders of the rotating frame, with the result that a locking device in the release position is at the latest put back into the blocking position when the rotating frame has been completely turned out. Basically, in addition to the previously described release devices for the locking members, 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.

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. In contrast to the embodiment according to FIG. 3, the tappet 10 is here connected to the locking member 17 by means of a rocker arm 21 which is pivotably mounted in the underframe and driver pins 22 — fixed to the tappet and 23 — fixed to the locking member. Another difference here is that 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.

Starting from the illustrated release position of the lock, 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.

With this embodiment, the translation between the relatively short stroke of the plunger 10 and the necessary lifting movement of the locking member 17 is better adjustable than with the pair of ramps 12 according to FIG. 3 or 4. It should also be noted that the FedeMOF are omitted in this embodiment could, because the spring 17F also pushes the plunger 10 (via the extension 27, the pin 23, the rocker arm 21 and the pin 22) into its normal position.

By manually actuating the hand lever 24 arranged below the level of the rotating frame - pivoting in the mounting of the shaft 25 - the eccentric piece 26 is pressed against the shoulder 27 and pushes the locking member 17 against the spring 17F supported on the shoulder 27 to the right. So that you can bring the bolt 16 regardless of the movement of the rotating frame 1 or the actuation of the plunger 10 at any time manually in its locked position.

All guides for the sliding locking components 10, 16 and 17 can be arranged in a cassette. The moving parts and their return springs can be preassembled and fitted with lifetime lubrication before being attached to the base frame. Of course, suitable measures must also be taken to prevent dirt from entering the guides. You can carry out the cassette with a removable lid, so that any repairs can be carried out easily after removing the lid.
