Definitions

  • the invention relates to a bolt and a counterholder of a bolt lock for hinged side walls of trucks according to the preamble of the preceding patent claim 1.
  • Bolt locks for foldable side walls of trucks are available in a wide variety of designs.
  • a very widespread latch tension lock is described for example in DE-PS 16 78 155. Its bolt is hook-shaped and screwed into a bolt stub so that the end position of the bolt can be adjusted by turning the bolt.
  • a frequently used slide bolt lock is given for example in DE-PS 23 61 914. In order to give such fastenings a catch-up ability, they have a run-up surface on the bolt and / or on the counter-holder which runs obliquely to the direction of movement of the bolt.
  • latch locks of the known type have a significant disadvantage.
  • the invention was based on the object of developing a device of the type in question so that when the cargo is pressed against the side wall the latch lock cannot be fully opened and this pressure is immediately noticeable when an attempt is made to open the lock.
  • the bolt lock can only be opened until the contact surface on the bolt presses against the contact surface on the counter holder. Since the contact surface lies in one step at the transition from the first to the second part of the run-up surface, the drop side falls slightly outwards so that the internal pressure is immediately noticeable.
  • the bolt and the counter holder can easily be designed so that a conspicuous drop of 10, 15 or even 20 mm is obtained.
  • the contact surface on the bolt and the contact surface on the counterholder run approximately perpendicular to the direction of movement of the bolt, the internal pressure must be removed from the side wall in order to open it again so that it can be brought back into its completely vertical position. As a result, the contact surface on the bolt and the contact surface on the counterholder disengage, so that the bolt lock can be opened completely and the side wall can be folded down.
  • the bolt has a bolt and two scissor-like bolt parts pivotable against each other.
  • the drive of the bolt and the pivotable bolt parts is such that, during the closing process, the pivotable bolt parts are first inserted into an opening in the counter-holder and then spread apart by subsequent advancement of the bolt.
  • the pivotable bolt parts and the bolt are collectively referred to in this patent as a bolt.
  • the pivotable latch parts each have lugs at their free ends, which engage behind the opening of the counterholder when the latch is closed.
  • the lugs have inclined surfaces with an inclination of about 45 o with respect to the direction of movement of the bolt, so that when the lock is pressed internally, one of the lugs slides on the adjacent edge of the opening in the counterholder when the lock is opened, which is why there is no effective inhibition of the opening process . Also, the patent does not mention anywhere that the bolt lock could not be opened completely when the inner wall was pressed.
  • a bolt lock is known, which differs from that described in DE-PS 38 17 220 in that the bolt is cylindrical and the pivotable bolt parts are replaced by a sleeve, which on its outer End is divided into elastic fingers by axially running, crosswise machined slots in the sleeve, which by the bolt can be spread.
  • the fingers have lugs on their outer ends, which engage behind an opening in the counterholder when the closure is closed.
  • the bolt is made up of several parts and is therefore weaker than a one-piece bolt, as is the case with the bolt according to the invention. If, after pulling back the bolt from the pivotable locking parts or from the slotted sleeve, they protrude into the counterholder alone, then the connection is weakened so that it cannot withstand a greater internal pressure and the pivoting locking parts or the sleeve are bent or even break off. In both locks, when the bolt is opened, the bolt is reduced in thickness, so that a drop in the side wall of a maximum of 2 to 3 mm can occur when the cargo is pressed against the side wall. However, due to its insignificance, this is not sufficient to make a possible existing charge pressure noticeable.
  • the hook-shaped bolt engages in the closed position behind a bar on the counter-holder.
  • the hook bolt can be T-shaped.
  • the contact surface can be provided on at least one lateral extension on the crossbar of the hook bolt. In this case, two such lateral extensions are preferably provided, on each of which a contact surface is arranged. A part of the ramp surface is preferably provided on each lateral extension.
  • the hook bolt it is also possible to design the hook bolt as a double-angled hook bolt in the case of a bolt-type tension lock and to provide the contact surface within the space delimited by the double angled portion.
  • the counter-holder has an opening into which the bolt is inserted in the closed position.
  • the counter holder can consist of a stanchion into which the opening mentioned is cut. But even with a slide bolt lock, contact surfaces could be provided in a similar manner on lateral extensions, as is the case with the above-mentioned embodiment of a bolt lock.
  • the device according to the invention of the first embodiment consists of a bolt 11, which is designed as a T-shaped double hook, and a counter-holder 14, which has the shape of a pocket.
  • the counter-holder 14 has a bar 15 divided in the middle, behind which the double hook engages in the closed position.
  • Lugs 16 are provided on the side of the T-bar of the double hook 11 and come into contact with their contact surfaces 12 on contact surfaces 13 of the counter-holder 14 when the closure is opened, if there is pressure on the side wall from the inside.
  • a complete opening of the lock is only possible in such a case if the side wall is relieved of the internal pressure and brought into its completely vertical position, since then the contact surfaces 12 and 13 move past one another when the latch is extended into the open position. So that a bolt lock provided with this bolt has a recovery capability, it has ramp surfaces 17 and 19, which correspond to ramp surfaces 17 and 20 on the counter-holder 14. Between the run-up surfaces 18 and 20 there is a step on the counter-holder 14 in which the contact surface 13 is located. This level is responsible for the fact that when there is internal pressure on the drop side when the lock is opened, the drop side clearly falls outwards, so that the inside pressure is recognized immediately.
  • the device according to the invention of the second embodiment has a bolt which is designed as a double-angled hook bolt 21. In the closed position, it engages with its free end behind a bar 25 of a counter-holder 24, which is also designed as a pocket.
  • the contact surface 23 on the counter-holder 24 lies between the two parts 28 and 30 of a run-up surface, to which a run-up surface 27 on the hook 21 corresponds.
  • the contact surface 23 lies in one Step between the two parts 28 and 30 of the ramp surface. The operation is the same as that of the first embodiment.
  • the device according to the invention of the third embodiment has a slide bolt 31 which, in the closed position, is inserted into an opening 35 of a counter-holder 34, which here consists of a stanchion.
  • the latch has an abutment surface 32, which comes into contact with internal pressure against the side wall in the course of the opening process with a surface serving as abutment surface 33 behind the opening 34 of the stanchion 35.
  • the contact surface 32 on the bolt 31 lies between the two parts 37 and 39 of the ramp surface.
  • the mode of operation corresponds to that of the second and third embodiments.
  • the device of the fourth embodiment according to the invention has a T-shaped hook bolt 41 and a counter-holder 44, which has the shape of a pocket.
  • the counter-holder 44 has a bar 45 divided in the middle, behind which the hook bolt engages in the closed position.
  • the bolt 41 has a run-up surface consisting of two parts 47, 49 separated by a step, a contact surface 42 being located in the step.
  • the counter-holder 44 has a run-up surface consisting of two parts 48, 50 separated by a step, a contact surface 43 being located in the step.
  • the mode of operation is readily apparent and corresponds to that of the three other embodiments.
