Definitions

  • the invention relates to a coupling piece for the detachable connection of containers, in particular stacked containers on board ships, according to the preamble of claim 1.
  • Dome pieces of the type mentioned are commonly referred to in the jargon as "twist locks”. These dome pieces are mainly used to connect containers to be transported on board ships. This should prevent relative displacement of the containers during ship transport. It is also conceivable to use such coupling pieces for attachment of containers or other objects on or in land vehicles (trucks, rail vehicles) or aircraft.
  • the invention relates to all types of coupling pieces, ie manual, semi-automatic and fully automatic coupling pieces.
  • All types of coupling pieces addressed here usually have a two-part housing. Through the center of the housing rotates a rotatably mounted therein Locking bolt.
  • the two housing halves are assembled in a parting plane, which usually extends approximately centrally through the housing and lies on the longitudinal central axis of the locking bolt.
  • This parting plane does not necessarily have to be a two-dimensional surface in the strictly geometrical sense; it can also be partially offset, so that the parting plane can also be spatially or three-dimensionally formed.
  • connection of the housing halves of known coupling pieces is carried out by extending transversely through the parting plane screw, bolts and nuts.
  • the dome pieces are exposed, especially when used on ships harsh environmental conditions, especially salty air or salt water.
  • the screw connections tend to corrode.
  • the result is that the screw connections can no longer be loosened when the coupling piece has to be repaired, which usually requires disassembly of the housing halves. Therefore, known dome pieces are virtually irreparable when it comes to replacing damaged parts inside the housing.
  • the invention has for its object to provide a coupling piece of the type mentioned that even with prolonged use allows a simple disassembly of the housing halves.
  • a coupling piece to solve this problem has the features of claim 1. Characterized in that the housing halves are connected by extending parallel to the parting plane and / or to the longitudinal central axis of the locking bolt elongated means, screw connections are unnecessary because the elongated means connect the housing halves form-fitting and only transverse direction are claimed shear and therefore only by simple fuses against falling out the receiving holes must be secured in the housing halves. The fuses can be easily removed even after prolonged use of the dome pieces, whereby the means for connecting the housing halves to open the housing can be easily disassembled at any time.
  • the coupling piece is provided that at least one housing half opposite the parting plane has protruding projections which engage in corresponding recesses of the at least other housing half. This results in a kind of toothing between the housing halves in the region of the parting plane.
  • This gearing extend the elongated Means and thereby bring about a positive connection of the housing halves.
  • the elongated means are only transversely stressed shear, but not in the longitudinal direction, which is unnecessary after a long time difficult to loosen screw connections.
  • the elongated means for releasably connecting the housing halves extend through both housing halves, preferably by receptacles in the one housing half and in the projections in the other housing half.
  • the receptacles for the elongated means are thus alternately in the different housing halves for effective positive connection of the two housing halves by the elongated means.
  • the means for releasably connecting the housing halves are designed as pin-like bolts.
  • Such bolts can be inserted to connect the housing halves through the receptacles in the housing halves.
  • the smooth outer surfaces having pin-like bolts do not require a thread for connecting the housing halves, which could corrode and therefore to - if at all - only allows a costly loosening of the housing halves.
  • the pin-like bolts hold the housing halves together in a form-fitting manner and need only be secured in the axial direction against displacement in the receptacles, preferably bores, of the housing halves.
  • Such fuses can be easily solved even with corroded coupling pieces.
  • the longitudinal axes of all bolts extend in a preferred embodiment of the coupling piece parallel to the parting line.
  • the longitudinal axes of the bolts extend at a parallel distance from the parting plane through a housing half.
  • the receptacles for the bolts in the projections and recesses of different housing halves can be located next to the parting plane and thus bring about a form-fitting, toothed connection of the housing halves outside of the parting plane.
  • the axial securing of the bolts in the preferably designed as bores receptacles in the housing halves can be done in various ways.
  • one end of the respective bolt receiving bore is closed or constricted, while the bore for the opposite end of each bolt is provided with a positive fixation.
  • this positive fixing can be achieved by the fact that after insertion of the bolt the caulked by this area of the corresponding hole is caulked and thereby the pin is secured in total form-fitting against falling out of the holes.
  • Another locking of the bolt against falling out of the holes provides at least one separate securing means.
  • such a securing means may be formed as an elastic sleeve surrounding the bolt, preferably a clamping sleeve or clamping sleeve.
  • a locking sleeve or clamping sleeve is positively accommodated in a housing half and then the bolt driven by this sleeve under resilient expansion of the same, whereby a frictional or non-positive connection between the bolt and the securing or clamping sleeve is made, whereby both a form-fitting as well as frictional or non-positive locking of the bolt in the housing is brought about.
  • the clamping or clamping sleeves also form-fitting, but releasably connected to the bolt.
  • the coupling pieces shown in the figures are designed as so-called semi-automatic twistlocks.
  • the dome pieces are used for semi-automatic connection of stacked containers, which are not shown in the figures.
  • the coupling pieces according to all three embodiments of the invention are composed essentially of a housing 10, a locking pin 11 and an actuating device 12. Notwithstanding the embodiments shown, the coupling piece may also have two actuating devices. The invention thus also relates to such coupling pieces, not shown.
  • the locking bolt 11 is composed of a substantially cylindrical central part 13 and two cross bars 14 and 15.
  • the locking bolt 11 is integrally formed, for which purpose the crossbars 14, 15 are formed at opposite ends of the cylindrical middle part 13.
  • the longitudinal central axis 17 extends in the in the Fig. 1 to 3 illustrated use position of the coupling piece vertically.
  • the two transverse bars 14 and 15 protrude from opposite ends of the housing 10. As a result, the crossbars 14 and 15 are located outside of the housing 10, namely - seen in the position of use of the coupling piece above and below the housing 10.
  • the crossbars 14 and 15 are designed in a conventional manner.
  • the lower cross bar 15 is tapered towards its free lower end and provided with a spiral.
  • the cross bar 15 leads to an automatic rotation of the locking bolt 11 when the dangling under an upper container coupling piece is deposited with the upper container on a lower container.
  • This rotation when threading the coupling piece in the upper corner fitting of the lower container leads to a spring preload after discontinuation of the upper container with the hanging dome piece on the lower container a turning back of the locking bolt 10 and thus automatically locking the coupling piece in the corner fitting of the lower container entails.
  • the free end of the opposite upper cross bar 14 is formed flat, because this cross bar is manually pre-locked by the actuator 12 under the lower corner fitting of the upper container.
  • the housing 10 of all dome pieces shown here is formed in two parts. It consists of two housing halves 18 and 19. In assembled housing halves 18 and 19 extends for the most part through the center of the housing 10, a vertical parting plane 20.
  • the parting plane 20 of the dome pieces shown is offset or profiled and thus not strictly geometric sense as a flat, formed two-dimensional surface, but three-dimensional.
  • the parting plane 20 extends centrally through the through-bore 16 in the housing 10, which is thus formed in each case half of the housing halves 18 and 19. In the parting plane 20 is thereby the longitudinal central axis 17 of the cylindrical central part 13 of the locking bolt eleventh
  • the two housing halves 18 and 19 are releasably connected to each other by elongate means, which extend parallel to the parting plane 20 and / or parallel to the longitudinal central axis 17 of the locking bolt 11.
  • elongate means which extend parallel to the parting plane 20 and / or parallel to the longitudinal central axis 17 of the locking bolt 11.
  • the elongate means for connecting the housing halves 18 and 19 need not be formed from screw connections (with screws and nuts); Rather, they are designed according to a further essential feature of the invention as threadless elongate means, which in the embodiments shown are elongated, cylindrical bolts 21.
  • threadless elongate means which in the embodiments shown are elongated, cylindrical bolts 21.
  • two parallel, preferably identical bolts 21 are provided to connect the housing halves 18 and 19 together to form the housing 10. But it can also be provided more than two bolts 21.
  • the housing halves 18 and 19 have protrusions 22 extending through the parting plane 20 and depressions 23 corresponding to the protrusions 22.
  • the projections 22 and recesses 23 extend from upright inner surfaces 24 and 25 of the housing halves 18 and 19, respectively. These inner surfaces 24 and 25 abut each other when the housing halves 18 and 19 are assembled, with the parting plane 20 extending between the inner surfaces 24 and 25. the inner surfaces 24 and 25 of the housing halves 18 and 19 with the parting plane 20 of the housing 10 coincide.
  • the projections 22 are arranged on a housing half 18, while the recesses 23 of the other housing half 19 are assigned. But it is also conceivable that each housing half 18 and 19 both projections 22 and recesses 23 has.
  • each connection 26 or 27 of the housing halves 18 and 19 to the housing 10 two spaced-apart same projections 22 are provided, which two equally spaced recesses 23 are assigned. Accordingly, the projections 22 of the other housing half 18 protrude into the recesses 23 of one housing half 19.
  • the two projections 26 and 27 associated with each connection 26 lie on a common, vertical connecting line 28, 29.
  • the connecting line 28, 29 of each connection 26, 27 runs parallel to the longitudinal center axis 27 of the locking bolt 11 and also at a parallel distance next to the parting plane 20.
  • the connecting lines 28 and 29 of both connections 26, 27 lie on the same side next to the parting plane 20, the distances of the connecting lines 28 and 29 from the parting plane 20 being different ( Fig. 4 ).
  • each projection 22 a vertical bore 30 and 31 is arranged in each projection 22, a vertical bore 30 and 31 is arranged.
  • the bores correspond to the diameter of the respective bolt 21.
  • the bores 30 and 31 of the projections 22 of the respective connection 26, 27 lie on the common connecting line 28 and 29, respectively.
  • the housing half 19, which has only the recesses 23 for engagement of the projections 22 of the opposite housing half 18 is provided with two through holes 32 which are spaced apart in the embodiment shown by a recess 33 in the housing half 19 between the through holes 32.
  • These through holes 32nd are thus in tongues 34 in the housing half 19, which are bounded on the one hand by a recess 23 and on the other hand by the recesses 33.
  • the through holes 32 correspond to the diameter of the respective bolt 21, in particular have the same diameter as the bores 30 and 31 in the projections 22nd

  • the two bolts 21 of the connections 26 and 27 form positive, toothed connections of the housing halves 18 and 19.
  • the connections 26 and 27 are easily releasable by axially pushing out the bolts 21 from the holes 30 and 31 and the through holes 32, along the connecting line 28 and 29, respectively.
  • the Fig. 1 and 3 show various embodiments of the coupling pieces, which differ only in that different fuses of the bolts 21 are provided for the positive connection of the housing halves 18 and 19. Because the bolts 21 for the positive connection of the housing halves 18 and 19 parallel to the longitudinal center axis 17 of the locking bolt 11 and the parting plane 20, they are loaded between the projections 22 and the tongues 34 to shear, but not axially. Consequently, the fuses of the bolts 21 in the housing 10 need only be designed so that thereby falling out of the bolts 21 from the bores 30, 31 and through holes 32 is prevented, so the bolts 21 are only axially secured in the housing 10. This backup can be done so that the bolts 21 have some play in the axial direction, so something in the housing 10 are displaced. The fuses only have to prevent the bolts 21 from falling out of the housing 10.
  • the bore 31 in a projection 22 (in the Fig. 1 in the lower projection 22) is designed as, for example, a blind bore.
  • the bore 31 is closed at the lower end or (as in the embodiment shown) is narrowed by a constriction 38, whereby the respective pin 21 through the lower end of the constricted bore 31 or blind hole in the lower projection 22 can not slip out.

So that the pin 21 can not slip upwards through the bore 30 in the upper projection 22, which is from the upper end of the bolt 21st released end portion of the bore 30 caulked in the upper projection 22.
  • This caulking is in the illustrated embodiment so formed by material deformation of the housing half 18, the upper end of the bore 30 is constricted by two opposing lugs 35. But it is also conceivable that serves for caulking only a single nose 35 or a circumferential constriction.
  • the nose formed by the caulking 35 for axial immovable securing the bolt 21 in the housing 10 can be reversed by re-material deformation.
  • the Fig. 2 shows an embodiment of the coupling piece, in which both bolts 21 are secured axially immovable in the same way in the housing 10, by a respective clamping sleeve 36.
