Definitions

  • Coupling piece for securing two stacked containers, in particular on board ships with a first coupling projection which is formed so that it engages in a corner fitting of a container, and a second coupling projection, which is formed so that it is in a Corner fitting of the other container engages, and with a Vorverriegelungs echo which is associated with the first coupling projection and a Vorverriegelungs ein in which the coupling piece against accidental falling out of the corner fitting of a container is safe when it is inserted there, and has an actuating position, in which the first coupling projection in the corner fitting of a container insertable or can be removed from the corner fitting of a container.
  • twiststackers are used to secure 20-foot containers loaded on ships in cell stands for 40-foot containers against horizontal displacement, without being secured against vertical lifting (at least this is not necessary in practice and therefore becomes not done). Twistlocks serve to secure, namely connect, containers loaded on the deck of a ship both against horizontal displacement and against lifting. Midlocks are used in conjunction with manual or semi-automatic twistlocks whenever 20-foot containers are loaded into 40-foot container slots.
  • a container If a container is loaded on board a ship, it is first lifted in the harbor by a crane. On land, a stevedores sets the dome pieces each with their first coupling projection in the lower corner fittings of the container. This first coupling projection is therefore also referred to in practice as the upper coupling projection.
  • the crane now lifts the container aboard the ship and places it on an already loaded container. In this case, the respective second coupling projection of the coupling pieces is inserted into the associated upper corner fitting of the lower container. This coupling projection is therefore also referred to as the lower coupling projection.
  • This coupling piece was easy to read Screw it into the lower corner fitting of the upper container and turn it out again after unloading.
  • the coupling piece is sufficiently secured against falling out, as long as no external forces act on the coupling piece, which turn it back. If, however, the coupling piece collides with an obstacle (for example, an adjacent container) during loading and unloading, there is a risk that the elements will undergo a reverse rotation and fall out of the lower corner fitting unintentionally.
  • the invention is based on the problem of providing an easy-to-use and at the same time secure pre-locking for a coupling piece.
  • the coupling piece according to the invention is characterized in that the Vorverriegelungs worn has a biased toward the Vorverriegelungs ein and when inserting the first coupling projection (1 1) in the corner fitting of a container automatically movable into the actuating position pawl. The stevedore then does not need to manually operate the pawl when he inserts the coupling piece in the corner fitting, but only if he removes the coupling piece from the corner fitting after unloading the container from the ship.
  • the pawl when inserting the coupling piece in the corner fitting is automatically moved into the operating position, the pawl may be provided according to a structural embodiment of the invention with an oblique outer surface, such that the pawl is wider when the first coupling projection in the corner fitting of a container is introduced. Due to the oblique outer surface, the pawl is automatically pressed when inserting the coupling piece in the corner fitting in the operating position.
  • the biasing force preferably acts on the pawl in a direction transverse to the longitudinal axis of the coupling piece.
  • the biasing force acts approximately in the same direction as the movement of the pawl from the operating position to the pre-locking position and is thus optimally utilized.
  • the pawl may be formed so that it bridges a game between the first coupling projection and an inner side of a slot in the associated corner fitting when the upper coupling projection is inserted into the corner fitting.
  • an elastic element is particularly suitable. This may be a compression spring and / or a (moss) rubber element. Of course, two or more elastic elements can be used parallel to each other. Further, the biasing force could also be provided by gravity or magnetic forces.
  • Pawl is guided through a recess in a shaft of the first (upper) coupling projection and abuts with a pivot bearing and with a lever arm opposite the pivot bearing on an inner wall of an inner bore through the shaft, but without being firmly connected to the shaft.
  • the pawl is free to move and can rotate in the operating position to the pivot bearing, but also to the hand lever or linearly.
  • a combination of these motion components is possible. As a result, the force required to automatically move the pawl into the operating position when inserting the coupling piece in the corner fitting is minimized.

  • the invention can equally well be used in conjunction with semi-automatic twistlocks, manual twistlocks, midlocks and twiststackers.
  • the coupling piece 10 has a first, upper coupling projection 11 and a second, lower coupling projection 12. Between the upper coupling projection 1 1 and the lower coupling projection 12 a pronounced, flange-shaped stop plate 13 is arranged in the present case. But there are also known coupling pieces, in which the stop plate 13 is reduced to a bead which engages in a groove formed by the phases on the slot of two consecutive corner fittings.

  • Both the shaft 14 and the support plate 15 are trapezoidal in the present case, as can be clearly seen in the plan view of Figure 3.
  • the support plate 15 protrudes T-like over the shaft 14. This results in the underside of the support plate 15 bearing surfaces 16 with which the support plate 15 engages behind the slot on the underside of a corner fitting, so that the coupling piece 10 does not fall out of the corner fitting while it hangs on the crane and safely during the sea transport with the associated Corner fitting remains connected.
  • a container If a container is to be loaded on board a ship, it is picked up by a crane. While the container is at a comfortable working height from the crane is raised, sets a stowage in each lower corner fitting of this container a coupling piece 10 a.

  • the coupling piece 10 is rotated so that the support plate 15 can be inserted through the slot at the bottom of the corner fitting, namely approximately in the position shown in Figure 3.
  • the rotation of the coupling piece 10 takes place about its vertical longitudinal axis, ie about an axis perpendicular to the bottom plane of the container.
  • the coupling piece must not unintentionally turn back and thereby accidentally fall out of the corner fitting, while the container is then heaved on board the ship. Otherwise, people such as stevedores or sailors would be endangered.
  • hi nterschnei-ended surfaces are provided to prevent such turning back. This works reliably as long as the coupling piece is not turned back by the action of external forces, such as by abutment against an adjacent container or other obstacle.
