Definitions

  • the invention relates to a hook and a counterholder of a bolt tension lock for hinged side walls of trucks, the counterholder having a strip behind which the hook engages in the closed position.
  • Latch latches for foldable side walls of trucks are available in a wide variety of designs. A very widespread embodiment is described for example in DE-PS 16 78 155.
  • the invention was based on the object of developing a device of the type mentioned in such a way that the locking latch cannot be opened easily when the load is pressing against the side wall.
  • a pivotable tab is attached to the end of the hook, which in the closed position engages with a recess projecting from the counter-holder, the length of the pin being such that it still engages with its recess when the hook comes free from the bar when the closure is opened, and the pin in the vicinity of its free end on the side facing the side wall has a groove into which the recess engages when when opening the closure, the borewall is pressed in the direction of the fold-down position.
  • the bolt tension lock can first be opened so far that the hook disengages from the counter-holder. Thereupon the drop side folds outwards somewhat and is then prevented from opening further by the fact that the recess of the tab engages in the groove of the pin.
  • the further opening process of the bolt tension lock now depends on the shape of the groove on the pin. If the groove on the side facing the free end of the pin has a surface that is perpendicular to the direction of movement of the bolt, then the internal pressure must first be removed from the side wall so that it can be brought back into its completely vertical position.
  • the recess of the tab comes out of engagement with the groove of the pin, so that the locking latch can be opened completely and the side wall can be folded down.
  • the groove on the side facing the free end of the pin has a surface that extends obliquely to the direction of movement of the bolt, then it is possible to open the closure completely by vigorously turning the hand lever, the tab with its recess on the mentioned sloping surface of the groove slides up.
  • the operator can decide whether, after latching the recess on the tab into the groove on the spigot, being aware of the internal pressure on the side wall, first of all eliminating this internal pressure or taking the risk of further opening of the bolt tension lock.
  • the hook can have a stop against which the tab comes into contact after a certain pivoting movement.
  • the hook above the pin engages the counter-holder, the tab hanging freely downward, so that the recess is flush with the pin when the drop side is fully raised before the closing operation.
  • the tab can of course also point upwards from its articulation on the hook. This alignment of the recess of the tab with the pin when the drop side is folded up makes it easier to close the latch tension lock.
  • the term "hook” should be understood to mean any structure which is suitable for gripping behind a bar on the counter-holder.
  • the hook consists of a T-shaped structure, with the two crossbeams of the "T” engaging behind a bar on the counter holder.
  • a ball or a disc can also reach behind a bar on the counter holder, so that they can also be regarded as hooks in the sense of the invention.
  • the recess on the tab preferably consists of a circular hole. However, it can, for example, also be designed as a quarter-circular recess, it only has to engage in the groove of the pin when the latch-type closure is half-open.
  • the groove on the pin must in any case be arranged on the side of the pin facing the side wall, but can extend much further around the pin, depending on the shape of the recess in the tab.
  • the device according to the invention consists of a counter-holder 1 and a hook 3 which, in the closed position, engages behind a bar 2 on the counter-holder 1.
  • a tab 5 is pivotally attached with the aid of a screw.
  • the tab 5 has a recess 6 in the form of a cylindrical hole, which engages around a pin 7, which is attached to the counter holder 1.
  • the pin 7 has a groove 8 on the side facing the side wall, which also goes somewhat around the underside of the pin 7.
  • a stop 9 is attached to the end face 4 of the hook 3, against which a projection of the tab 5 comes into contact after a certain pivoting movement.
