Definitions

  • the invention relates to a closure for a movable body part of trucks, containers and the like, with a rotary bolt which is rotatably mounted on a carrier and can be screwed in behind a counter element of a fixed body part, which is connected by a hand lever articulated to the carrier via a crank arm of the rotating bolt on the one hand and on the other hand the link which is articulated on the hand lever is rotatable, the hand lever being held down in the closed position by an over-center position of the articulation points, the axis of rotation of the rotary latch being displaceable and the length of the link between the hand lever and the crank arm on the rotary latch being such that during the closing process after ended rotary movement of the rotary latch of the hand lever is not yet closed, and in addition a slide is provided on the carrier, which is articulated by a pushing member articulated on the one hand and on the hand lever when the hand lever is closed the rotary bolt is pushed into a position locking the rotary movement of the rotary bolt.
  • the object of the present invention was to improve the known closure.
  • the first additional feature ensures that the closure remains in the fully open position after opening and folding down the side wall. If the lock is not fully open, it can happen that when the side wall is folded up, the rotary latch does not find its way into the locking opening provided for it, for example in a stanchion or in a counterholder. With a preferred off.
  • the spring is arranged in a bulge of the slide, wherein it is supported on the one hand on the slide and on the other hand on a shoulder on the carrier.
  • a locking device is provided on the hand lever, which secures the closed position in addition to the dead center coating against unintentional opening.
  • This locking device preferably consists of a slide supported by a spring, which has at least one hook-shaped projection which engages in a corresponding recess in the pushing element which extends between the hand lever and the slide.
  • the rotary bolt in the closed position the rotary bolt simply inserted into an opening of an adjacent structural part, such as e.g. a stanchion.
  • the mounting part is weakened, so that, in particular for highly stressed bodies according to the third feature, the rotary latch is assigned a counter-holder which is arranged on the fixed mounting part and on which there is a projection which the rotary latch engages behind in the closed position.
  • a rib is provided on the counter holder on the side of the projection facing away from the closure, which rib engages in a corresponding recess on the rotary latch. This rib and the recess serve as a guide for centering the closure with the counter holder during the closing process.
  • a hold-down device is provided on the slide, under which the crank arm on the rotary latch or a part connected to it is placed at the end of the closing process.
  • a hold-down device is already known according to the prior art mentioned above.
  • the hold-down device is provided on the carrier of the closure so that it cannot move. It has been found that it is better to provide the hold-down device on the slide, because the hold-down device is then advanced together with the slide during the closing process, so that the rotary latch and the hold-down device move against each other during the closing process and thus result in better engagement comes between the hold-down device and the rotary latch or the part firmly connected to it.
  • the closure has a built-in trough 11 as a carrier, as is customary for closures of the type in question.
  • a longitudinally displaceable bearing block 13 for a pivot axis 14 of a hand lever 15 is arranged, which is supported by a block 16 supporting compression spring 17 is pressed against the rear side wall of the installation tray 11.
  • the block 16 has lateral lugs 18 which, together with the extension 12 and the bottom of the trough 11, result in a guide for the bearing block 13.
  • the arrangement of the bearing block 13, which is displaceable against spring pressure, results in a resilient arrangement of the entire locking mechanism in order to prevent the hand lever from being able to be closed due to the distance of the counter element on the fixed structural part. In such a case, the entire locking mechanism can move forward against the pressure of the spring.
  • the hand lever 15 On the underside of the hand lever 15 there are two ribs 19, by means of which the hand lever is pivotably attached to the articulation axis 14. Behind the articulation axis 14 there are two short articulation axes 20, by means of which two connecting links 21 are articulated on the ribs 19 of the hand lever 15. At the other end, the connecting links 21 are connected to one another by an articulation axis 22.
  • This articulation axis passes through the free end of a crank arm 25 of a rotary bolt 23 which is rotatable about a free axis 24.
  • the axis of rotation 24, which is firmly connected to the rotary bolt 23, is guided in elongated holes which are formed in the side walls of the installation trough 11.
  • the length of the connecting links 21 is dimensioned such that during the closing process after the rotary movement of the rotary latch 23 has ended, the hand lever 15 is not yet closed, so that when the hand lever 15 is closed further on the rotary latch 23, the connecting links 21 only move and no more torque exercise. In the last part of the closing process, the rotary latch 23 therefore only makes a linear movement. He is supported with a lower projection 27 on a slide 34 described in more detail below.
  • the installation trough 11 has, as usual, a depression 28 at its front end, so that it is not necessary to cut open a side border profile of the side wall when installing the closure on the front side of the side wall. In this front area, the installation trough 11 has a recess 29 on its base in order to enable the rotary latch 23 to rotate.
  • the correct distance between the connecting members 21 and the crank arm 25 is provided by spacer bushings 30.
  • the aforementioned slide 34 pushes itself under the movement of the rotary hook 23 in the closed position and supports it.
  • two thrust members 35 are provided, which are articulated on the one hand on the hand lever 15 by the articulation axis 20 'and on the other hand on the slide 34.
  • Two upright tabs 36 serve for the articulation of the slide.
  • the slide closes the recess 29 in the closed position and supports the rotary hook 23 over almost its entire length.
  • a bulge 51 is provided in the slide, into which a projection 52 attached to the bottom of the installation trough 11 projects.
  • a spring 53 which is supported on the one hand on an end face of the bulge 51 and on the other hand on the shoulder 52 in such a way that it pushes the slide and thus the entire closure into the open position.
  • the projection 27 on the underside of the rotary bolt 23 has a corresponding recess into which the bulge 51 bulges.
  • Two projections 54 are provided on the crank arm 25, which engage in the closed position under the hook-shaped hold-down device 55 on the slide 34. If the locking bolt 23 experiences a torque due to internal pressure on the side wall, then the locking mechanism is relieved by this hold-down device.
  • the rotary latch 23 has a groove 57 on its underside, which in the closed position engages behind a projection 58 on a counter-holder 56. Following the projection, a rib 59 is formed in the center of the counter-holder, which engages in a recess on the underside of the rotary latch 23.
  • a slide 60 is provided on the underside thereof, which projects slightly beyond the hand lever.
  • a spring 63 is accommodated, which is supported on the one hand on a shoulder 62 on the hand lever 15 and on the other hand on an end face of the bulge 61 of the slider 60.
  • the slider also has two hook-shaped lugs 64 which engage in corresponding recesses 65 on the thrust members 35 in the closed position. By moving the slide against the action of the spring 63, the hook-shaped lugs 64 can be brought out of engagement with the recesses 65 so that the hand lever 15 can be opened.
