Definitions

  • the invention relates to a coupling piece for releasably connecting containers according to the preamble of claim 1.
  • the coupling pieces (twistlocks) mentioned here are mainly used during the transport of containers on ships.
  • the coupling pieces should on the one hand reliably prevent relative displacements of the containers from one another and, on the other hand, relative displacements of the containers relative to the ship. It is important that all containers are reliably connected to each other and to the ship. Missing or inadequate connections can cause the containers to slip at sea, with the result that damage to the containers and of the cargo contained therein and in particularly unfavorable cases, for example in heavy seas, the ship can capsize.
  • a coupling piece is known from FR-A-2 084 265 which has an indicator tongue which, when the coupling piece is locked, partially protrudes from an opening in the housing of the coupling piece to indicate whether the coupling piece is locked is.
  • the display tongue is brought into its display position by a positive connection with a locking bolt of the known coupling piece.
  • the coupling piece cannot be locked automatically when the end of the display tongue jams in the opening.
  • Such a jamming is to be feared, for example, when seawater that has accumulated in the housing freezes. It is also conceivable that the opening is blocked from the outside, so that the end of the display tongue cannot come out of the housing.
  • the object of the invention is to create a coupling piece which ensures a reliable display of at least the locked state.
  • the coupling piece according to the invention has the features of claim 1.
  • the flexible movement means that the locking bolt of the coupling piece can be moved even when the display tongue is clamped, and thus the coupling piece can in particular be brought automatically into its locking position. The function of the coupling piece is thus retained - apart from the display tongue.
  • the flexible movement member in the housing, namely in a transverse plane to the longitudinal direction of the locking bolt between part of the outer circumference thereof and a correspondingly formed inner wall of the housing.
  • a movement of the display tongue with respect to the housing arises from the fact that when the locking bolt is turned, the actuating member partially loops around the outer surface of the latter.
  • a Bowden cable or a rope fastened between the locking bolt on the one hand and the indicator tongue on the other hand can be considered as the actuating element.
  • this is in an elastically deformable covering made of a spiral spring, a rubber hose or the like for precise transmission of the rotational path of the locking bolt on the display tongue, in opposite directions.
  • Such movement organs have the advantage that they are not only inexpensive and compact; rather, they also have reliability that meets the requirements set here.
  • the coupling piece shown here is used to connect superimposed containers, of which the corner fittings 10 and 11 to be connected are only indicated (dashed lines) in FIG. 1.
  • the coupling piece has a housing 12 in which a locking bolt 14 is rotatably mounted about a vertical axis of rotation 13. The opposite ends of the locking bolt 14 are integrally connected to a respective cross bar 15 or 16 located outside the housing 12.
  • the coupling piece shown here is designed as a semi-automatic three-function coupling piece, in which the crossbars 15 and 16 can be brought together into a locking position relative to the corner fittings 10 and 11 by turning the locking bolt 14 and, in addition, one of the crossbars 15 and 16 can be brought into an unlocking position to a corresponding corner fitting 10 or 11.
  • the coupling piece is first with its (upper) Cross bar 15 locked under the lower corner fitting 10 of the upper container.
  • the (lower) crossbar 16 is then automatically locked the locking bolt 14 with the transverse bolts 15, 16 arranged thereon is referred to.
  • the housing 12 of the coupling piece shown here is formed in two parts, namely consists of two housing halves 19 and 20 connected by screws indicated by dashed lines.
  • the housing 12 thus has a vertical, approximately central division plane 21.
  • the housing 12 is divided into three sections, namely a central abutment 22, which is located as a spacer between adjacent corner fittings 10 and 11 of the stacked containers, and two middle pieces 23 and 24 located on opposite sides of the abutment 22.
  • the middle pieces 23 and 24 enter elongated holes 25 and 26 in the corner fittings 10 or 11 and are designed accordingly to the same.
  • housing 12 there is a vertical, continuous housing bore 27, the longitudinal center axis of which coincides approximately with the axis of rotation 13 of the locking bolt 14.
  • the locking bolt 14 can thus be rotated in the housing bore 27, which runs centrally through the parting plane 21 of the two housing halves 19, 20.
  • an (elongated) display tongue 28 with an approximately rectangular cross section (FIG. 1) is mounted in the housing such that it can be moved back and forth.
  • the footprint of the Indicator tongue 28 is dimensioned such that it can be moved completely into the housing 12.
  • the display tongue 28 is located in the abutment 22 of the housing 12, in such a way that the display tongue 28 can be freely moved back and forth between the stacked corner fittings 10 and 11 of containers placed one on top of the other.
  • a flexible movement member is used to move the display tongue 28 back and forth in the housing 12.
  • it is designed as a wire cable 29 that transmits both tensile and compressive forces with respect to the longitudinal axis.
  • This wire rope 29 is fastened at one end 30 by suitable means to the end region of the display tongue 28 projecting towards the interior of the housing 12, while the opposite end 31 of the wire rope 29 is connected to the locking bolt 14. specifically with a fastening tab 32 pointing radially outward to the axis of rotation 12 thereof.
  • the wire cable 29 for actuating the display tongue 28 is surrounded by an elastically deformable covering, namely a compression spring 33.
  • the compression spring 33 guides the wire cable 29 in a partial annular space 34 formed in the interior of the housing 12 between the outer circumference of the locking bolt 14 and an inner wall 35 of the housing 12 running approximately parallel thereto.
  • the end of the compression spring 33 which is toward the display tongue 28, is not supported on the display tongue 28 but on a stop surface in the interior of the housing 12.
  • the end of the compression spring facing away from the display tongue 28, like the wire cable 29, bears against the fastening tab 32 of the locking bolt 14.
  • the compression spring 33 serving as a covering for the wire cable 29 can - as in the present exemplary embodiment - Be provided with a further function in which it serves in the semi-automatic operation of the coupling piece for moving back the locking bolt 14 by abutment against a switching lug 36 on the operating lever 17 on the one hand and a switching cam 37 on the locking bolt 14 on the other.
  • FIG. 3 shows an unlocking or pre-locking position of the coupling piece, in which at least one of the two cross bolts 15 or 16 is in an unlocked position relative to the corner fittings 10 or 11 of the container.
  • the display tongue 28 is partially moved out of the housing 12 by the wire cable 29 actuated by the locking bolt 14, so that part of the display tongue 28 projects laterally from the abutment 22 of the housing 12.
  • the length of the area of the display tongue 28 protruding from the abutment 22 of the housing 12 is dimensioned such that at least a part of this area of the display tongue 28 which has become free protrudes from a vertical plane which is formed by corresponding side walls of containers lying one above the other.
  • the display tongue 28 is readily visible in the fully or partially unlocked state of the coupling piece if one looks from above into a gap between the side walls of adjacent container stacks facing each other.
  • the display tongue 28 is at least partially contrasted in color with respect to the coupling piece, in particular the housing 12 thereof.
  • the entire display tongue 28 is provided with a striking color coating.
  • this color coating can have a signal red color.
  • bright, fluorescent colors are particularly suitable for the color coating.
