Definitions

  • the invention relates, according to the preamble of claim 1, to an espagnolette lock for doors of commercial vehicle bodies, transport containers and the like, with a handle for rotating the pivot rod and with at least one locking part at one end of the pivot rod, which is locked in the closed position against a counter-holder, the Locking part has a radially protruding arm, which turns behind a hook on the counter-holder during the closing process and thereby pulls the door forward and which is supported on the hook after the closing process has ended.
  • a espagnolette lock of this type is known from DE-PS 19 60 697. It has the advantage that it can be completely unlocked by turning the rotary rod by 90 ° using the handle. So you can open the door in this position by pulling the handle. This is particularly important for box bodies of refrigerated vehicles, because the sealing strips on the door frame can stick to the door quite firmly, especially after a long journey.
  • a disadvantage of this closure is the fact that when there is internal pressure against the door, which can arise, for example, from the load slipping, there is a torque on the rotary rod which acts on the handle, which is why both the rotary rod and the handle together with the holding device , with which the handle is fixed in the closed position of the closure, must be designed to be excessively stable. In addition, with very strong internal pressure, torsion of the rotating rod can even occur, with the result that the door no longer lies correctly against the door frame.
  • the invention was based on the object of further developing an espagnolette lock described in the introduction so that in the closed position no torque or a significantly reduced torque occurs when an internal pressure acts against the door without losing the property that for completely unlocking the lock
  • the rotating rod only has to be turned 90 °.
  • the further development of the above-described espagnolette lock that solves this task consists in that a further hook is arranged on the counter-holder, which is directed against the first hook and which engages over the locking part in the closed position, a surface in this position of the locking part rests on the inside of the end part of the further hook and the locking part has a recess at the height of the further hook, the shape and position of which are such that the locking part does not overlap the further hook in a position rotated by approximately 90 ° with respect to the closed position becomes.
  • a further development according to claim 2 is that in the closed position of the further hook overlaps the central axis of the rotary rod and that the recess on the locking part extends beyond the central axis of the rotary rod.
  • a further development according to claim 3 is that in the closed position, the further hook does not reach over the central axis of the rotating rod and, accordingly, the recess on the locking part does not extend to the central axis of the rotating rod, and that, in the closed position, the radially protruding arm of the locking part is also included supports its end face on the first hook.
  • a further hook is provided on the counter holder, which in the locking position engages over the locking part, in which position a surface of the locking part rests on the inside of the end part of the further hook.
  • the further hook reaches over the central axis of the rotating rod or the radially protruding arm of the locking part has its end face on the first hook supports the counter-holder.
  • the latter embodiment has the further advantage that the overall height can be kept lower. Because the locking part also has a corresponding recess in a suitable shape and arrangement at the height of the further hook, the locking part can be guided past the further hook when the door is opened after turning the rotating rod by 90 °.
  • a further development of the espagnolette lock of claim 3, described in claim 4, consists in the fact that the espagnolette is passed through the locking part and connected to it, the recess on the locking part extending as far as the turning rod.
  • the further hook on the counter holder does not extend beyond the central axis of the rotary rod, so that the recess on the locking part can be kept relatively small. It is therefore possible to pass the rotating rod through the locking part.
  • the geometry of the arrangement of the locking elements is also such that the rotary rod must be rotated from the locking position to the unlocking position by almost 180 °, so that such a closure has the disadvantages that its handle can not be used to open the door by pulling can and that it can not be installed in the door, because in such a case the handle is in a tub and a pivoting of the handle and thus a rotation of the rotating rod by more than 90 ° is impossible impossible.
  • Another espagnolette lock in which no torque occurs when the door is pressed internally, is known from US Pat. No. 3,464,729. With this closure, a two-armed locking part, which is arranged on the rotating rod, is supported in the locking position on two pins of the counter-holder, which are each located to the side of the rotating rod.
  • the recess has inclined run-up surfaces on its lateral flanks, which run-up surfaces on the counter-holder correspond to. Such run-up surfaces slide on each other during the closing process, which means that sagging doors are raised so that they are brought into the correct position with respect to the door frame.
  • the radially projecting arm of the locking part is formed at its free end as a catch hook, which in the closed position engages behind a strip at the free end of the first hook of the counter-holder, the contact area of the catch hook has such a contour that the part of the contact area which is immediately adjacent to the angle of the catch hook is at a greater distance from the central axis of the rotating rod than another part of this contact area which is closer to the free end of the catch hook.
  • the catch hook can be equipped with a smaller or larger return.
  • the lock can be opened when there is internal pressure against the door by exerting more force when operating the handle. This can be necessary, for example, with closed vehicle bodies or transport containers be because it is not possible to get into such a closed container to remove the slipped load from the inside of the door. If a larger recess is provided, the door can only be opened when the internal pressure against the door has been removed.
  • a hole for passing a fastening screw is provided on the counter-holder, which is covered by the locking part in the closed position.
  • This measure serves customs security. In the case of transport containers sealed by customs, it is necessary that the door of the transport container cannot be opened without breaking the seal. If at least one hole, through which a fastening screw for the counter-holder passes, is covered in the closed position, this screw cannot be opened, so that it is impossible to open the door by unscrewing the counter-holder without damaging the seal so that the cargo is out can be removed from the sealed vehicle body or transport container.
  • the counter-holder has a base plate 1 with a first hook 2 projecting therefrom and a second hook 3 also projecting therefrom. With the aid of holes 4, the counter-holder can be attached to the portal or door frame of a box body.
  • the locking part has a cylindrical section 5 with a likewise cylindrical pin 6, which is used for fastening to a rotating rod.
  • An arm 7 with a nose 8 projects radially from the cylindrical section 5.
  • the arm 7 has a lowering 9 to save weight.
  • the cylindrical section 5 also has a recess 10 extending beyond its central axis.
  • the start of the closing process is shown in Figure 3.
  • the arm 7 is initially supported on the base plate 1.
  • the position of the recess 10 is such that the free end of the hook 3 is at a distance from the bottom of the recess 10 (indicated by dashed lines).
  • the arm 7 is pivoted so that the cylindrical section 5 can be brought further to the counter-holder.
  • its nose 8 comes into contact with the free end of the first hook 2.
  • the cylindrical section 5 is then brought closer to the counter-holder.
  • a contact surface 11 is then guided under the second hook 3 until the state shown in FIG. 4 is reached after a total rotation of 90 °. In this position, the hook 11 supports the central axis of the cylindrical section 5, so that a torque-free locking of the locking part in the counterholder takes place.
  • the recess 10 has inclined run-up surfaces 12 on its side flanks, which also correspond to inclined run-up surfaces 13 that start on the side surfaces of the second hook 3 and continue up to a central projection 14, which in the closed position extends into the recess 10 of the locking part. Due to the sliding of the run-up surfaces 12 and 13 during the closing process, the locking part is height-centered with respect to the counter-holder.
  • the counter-holder has a base plate 1 'with a first hook 2' protruding therefrom and a second hook 3 'also protruding therefrom.
  • a base plate 1 ' With the help of three holes 4 'the counterholder on the portal or.
  • Door frame of a box body to be attached.
  • the central hole 4 ' is covered in the locking position of the closure (Fig. 8) to achieve customs security.
  • the locking part has a cylindrical section 5 ', through which a likewise cylindrical rotary rod 6' extends and which is connected to it.
  • the cylindrical Section 5 ' has a recess 10' extending to the rotating rod 6 '.
  • the arm 7 ' is first inserted between the two hooks 2' and 3 'until it is supported on the base plate 1'.
  • the position of the recess 10 ' is such that the free end of the hook 3' is at a distance from the base of the recess 10 '.
  • the arm 7 ' is pivoted so that the cylindrical section 5' is brought further to the counter-holder, as shown in FIG.
  • the rotary rod 6 ' has been rotated further and the arm 7' has been pivoted, the latter comes into contact with the free end of the first hook 2 '.
  • the cylindrical section 5 ' is then brought even closer to the counter-holder.
  • a contact surface 11 ' is finally guided under the second hook 3' until the state shown in FIG. 8 is reached after a total rotation of 90 °.
  • the locking part is supported twice against opening the door on the counter holder.
  • the first support consists in the already mentioned overlapping of the second hook 3 'over the cylindrical section 5' of the locking part, while the second support comes about because the arm 7 'rests with its end face 8' on the first hook 2 '.
  • a torque-free locking of the locking part in the counter holder is hereby achieved.
  • the recess 10 ' For centering the height of the locking part with respect to the counter-holder, the recess 10 'has inclined run-up surfaces 12' on its lateral flanks, which also correspond to inclined run-up surfaces 13 'on the counter holder. Due to the sliding of the run-up surfaces 12 'and 13' during the closing process, the locking part is centered in height with respect to the counter-holder.
  • This embodiment of the espagnolette lock according to the invention also has a catch device which prevents the lock from being easily opened when the internal pressure is exerted on the door by slipped cargo.
  • the first hook 2 ' has an opening 15', so that a bar 16 'is formed.
  • the radially projecting arm 7 ' has a hook-shaped extension 17' which springs back at its free end in the direction of the central axis of the rotary rod 6 '.
  • a espagnolette lock normally has a locking part and a counterholder on its top and bottom.
