Definitions

• the invention relates to a lock between a rotating frame and e ; nem container with the features of the preamble of claim 1.
• Rotating frame is called pivoting support frames for holding containers on road or rail vehicle undercarriages. Reliable locking of the containers resting on the rotating frame during the journey is essential for the operational safety of such transports.
• the generic features of claim 1 are known from EP 0 516 584 A1.
• the locking device described there and its actuating linkage are arranged in the vehicle underframe.
• Two mutually opposite retaining claws are provided as bolts, which are coupled to one another by a shaft with bevel gear drives at the end. They rest spring-loaded from above on webs of the long container girders, but without engaging them positively, so that they can at most force-fit the container in the longitudinal direction or in the direction of travel of the vehicle.
• a Ver ⁇ egelungsvor device in which two locking arms pivotable on a common axis, which is also the pivot axis of the rotating frame. are stored in the base. The two locking arms place the patch The container is fixed directly opposite the underframe, so that the rotating frame itself is also indirectly secured by this device. In this device there is no controlled interaction between a pivoting movement of the rotating frame and the unlocking or locking of the container on the same Locking difficult because the latches are placed on the inside of the container base.
• the invention is based on the object of locking the type mentioned in such a way that it is suitable for a form-fitting fixing of the container on the rotating frame both in the longitudinal direction and in the vertical with a comparably comfortable and safe operation and simple structure.
• the bolts are pivotally mounted in the rotating frame itself, preferably in a plane lying parallel to its loading plane, so that when the rotating frame is pivoted out, guide means are carried along. preferably a guide link, for coupling and synchronization of the bolt and the rotating frame movements are provided in the base frame.
• the bolts can fix the container by lateral engagement from the outside in recesses in its base frame in both vertical and horizontal directions - And engaging movements are forced without separate actuation directly by the relative movement between the rotating frame and the guide means fixed to the frame
• the container is normally pushed onto the rotating frame up to a position defined by a stop on the face side.
• a signal device can be provided on the rotating frame side, which clearly indicates to the operating personnel that this position has been reached, because the above-mentioned recesses are now independent of each container
• the engagement of the bolts when the pivoting frame is pivoted back is also ensured.
• the bolts therefore only need one hook side oriented towards the abovementioned stop.
• Figure 1 is a plan view of a rotating frame with the essential components of the lock according to the invention, wherein the bolts are shown in a locked position.
• Figure 2 is a view corresponding to FIG. 1, in which the latch without pivoting the
• Swivel frame are brought into an unlocked position
• FIG. 3 shows a sectional view of one of the bolts
• FIG. 4 shows a plan view of a variant of the bolt structure in FIG. 1,
• FIG. 5 shows a sectional view of one of the bolts according to FIG. 4.
• a rotating frame 1 which is pivoted in a known manner about an axis 2 on an only indicated base frame, according to FIG. 1 there are two bolts 3 and 4 of a lock for a container, also not shown, which can be pushed onto or placed on the rotating frame about vertical axes 5 or 6 pivotally mounted. Their pivoting plane is therefore parallel to the loading plane of the rotating frame 1. They are essentially designed as two-armed angle levers.
• the shorter leg 3K or 4K has a hook side H and a support surface S facing away from it and converging towards the hook side.
• the other longer leg 3L / 4L establishes the connection to guide means 7, which are arranged in the base frame and in FIG. 1 by a curved dash-dotted line is represented.
• the guide means preferably comprise a link or guide curve in which a guide member of each bar is positively guided.
• the bolts have a slight radial bearing play around their swivel axes. This enables the bolts to give in when the load on the rotating frame is pushed in the direction of the bolts by shocks during transport and presses against the hook side H.
• fixed abutments W are provided on the rotating frame, against which the rounded support surface S of the latch abuts before the bearing play is completely used up. This keeps the load away from axes 5 and 6 respectively. The release of the bolts is supported in the tensioned case by the draining effect of the support surface.
• the guide means 7 have a central section 7M, within which the link or guide curve describes a circular section around the axis 2, and then a ramp section 7R and a neutral section 7N symmetrically on both sides.
• the latter can be straight or also a segment of a circle around axis 2. Dashed and double-dotted lines indicate a shifted position of the center section, which will also be discussed in more detail.
• An embodiment for a guide member is sketched in FIG. 3 using the example of the bolt 3. It is designed here as a pin 8, which projects downward from the longer locking leg 3L (4L) and protrudes into said backdrop of the guide means 7, in which it is guided on both sides as between rails.
• a roller bearing 9 is arranged on the pin 8 to reduce friction and wear and can roll along the wall of the pillow case.
• the connecting member of the bolt 3 runs from the central section 7M directly onto the adjacent ramp section 7R and is guided away from the axis 2 therein.
• the bolt 3 is also pivoted counterclockwise with respect to the rotating frame with respect to its axis 5 until its guide member reaches the subsequent neutral section 7N. The relative pivoting of this bolt has essentially ended, and the associated abutment in the container has been released.
• the connecting member of the bolt 4 is first guided in the central section 7M on a circular path around the axis 2, so that there is still no relative movement between the bolt 4 and the rotating frame 1. This also prevents undesirable additional clamping forces at the start of the release movement.
• the container remains secured on one side.
• the bolt 4 is only at the start of its guide member on the ramp section 7R towards the end of The pivoting movement of the rotating frame is pivoted out with respect to the axis 6 in the clockwise direction and the loaded container is fully released.
• the guide members 8 in the basic position in the central section 7M of the guide means 7 can have the bolts at an angle to the normal guide curve on circular paths around the bolt axes 5 and 6 are moved simultaneously, whereby a synchronous opposite pivoting movement of the bars 3/4 is generated.
• This fulfills the requirement that the container should at least be able to be lifted off by means of a crane if necessary in the transport position of the rotating frame.
• the center section 7M of the guide means 7 can be moved as a whole in a straight line with respect to the base frame, as indicated by double-dotted lines in FIG. 1 and shown in the disengaged position in FIG. 2. He takes the guide members lying in his kiss section with him and brings about the release movement of the bolts 3, 4. The hook sides of the bolts 3 and 4 are evidently completely swung out of the overlap with the container guide of the rotating frame.
• movable slides could be provided in the middle section, which can push the guide members out of the guide track into suitable branch tracks
• the bolts 3 'and 4' which are pivotably mounted in the rotating frame 1 about axes 5 'and 6' fixed to the rotating frame are designed as slightly outwardly bent, two-armed angle levers which approximately the short locking legs 3K / 4K correspond to the first described embodiment.
• a link 10 and 11 respectively, which is connected to the leg facing away from the hook side H in a joint 10G and 11G.
• the two links 10 and 11 in turn each carry at their ends facing away from the bolts 3 'and 4' the guide members 8 which are positively guided in the manner already described in a guide track T fixed to the frame.
• the two links 10 and 11 are also articulated by coupling rods 12 , so that their guide members are guided equidistantly within the guideway 7 '.
• the guide members 8, again designed as bolts, according to FIG. 2, form the two joint axes of the coupling rod.
• the coupling rods 12 could be made variable in length in order to be able to readjust the bolts if necessary.
• the guideway 7 ' is shaped like a widened U in the overall view and is therefore more simply shaped.
• a pivoting movement of the rotating frame inevitably leads to the loosening of the two latches 3 'and 4'.
• ramps 7R of the guideway 7 ' force the guide members of the coupled links 10 and 11 and the joints 10G and 11G closer to the axis 2 .
• This widens the angle enclosed between the handlebars and the respective bars.
• the bars 3 'and 4' are swung out in opposite directions and release the container or the loading area of the rotating frame. A certain time delay between the movements of the latches on both sides can occur, but both latches 3 'and 4' are safely released in the swung-out fold position of the rotating frame.
• the guideway 7 'can also have means for releasing the latches 3' / 4 'without the pivoting movement of the rotating frame.
