Definitions

• the invention relates to a coupling piece for coupling two stacked containers with each other, in particular on board ships, engaging in a lower corner fitting of the upper container upper coupling projection and engaging in an upper corner fitting of the lower container lower coupling projection, which in the longitudinal direction of the container Seen laterally arranged coupling nose and a remote from the coupling nose side of the lower coupling projection arranged vertical rear wall, such that the distance of a free edge of the coupling nose to the rear wall is less than or equal to the width of an upper slot in the upper corner fitting.
• Such a coupling piece is known from DE 102 38 895 AI.
• the invention is based on the problem of further developing the coupling piece mentioned above in such a way that it reliably couples two containers stacked on top of one another, even in the case of pure tensile forces, and prevents "Z movements" during coupling and uncoupling.
• the coupling piece according to the invention is characterized in that the lower coupling projection in the rear wall has a groove extending over the entire length of the lower coupling projection recess.
• the coupling piece according to the invention is thus designed substantially like a fully automatic twistlock according to DE 102 38 895 A1. However, it is provided in the rear wall of the twistlock a groove-like recess. As a result, there is no longer a "Z movement" when connecting and disconnecting. If, despite all precautions, the coupling nose on the tension side slides out of the associated corner fitting, that is to say free of this corner fitting behind the edge of the upper slot, the upper container on the lower container slides horizontally in a direction which the skid tion, in which the coupling nose points, is opposite, ie in the direction of the recess. As a result, the edge of the upper slot opposite the coupling nose engages with the recess, so that the coupling piece is not completely decoupled. The upper container remains coupled to the lower container.
• the coupling piece according to the invention thus has certain emergency running properties.
• the sloping shoulder need not be as flat as an oblique shoulder of the coupling nose.
• the angle of the shoulder to a rear wall of the lower coupling projection can therefore be greater than the angle of the shoulder of the coupling nose to a front wall.
• the shoulder of the nose is aligned with an inner surface of a recessed grip in the lower coupling projection.
• the dome pieces are usually made of cast steel and the flush shoulder, the mold is simplified.
• the recess On a side opposite the nose, so on a side facing the upper coupling projection side, the recess is limited according to an embodiment of the invention by an insertion oblique. Should the recess in the manner described above come to fruition or the edge of the slot when coupling the coupling piece with the upper corner fitting lower container accidentally get into the recess (which may occur due to wind pressure or a pendulum of the container on the crane) is Insertion bevel ensures that the coupling piece (again) reaches its coupled position.
• FIG. 1 is a coupling piece with the Erfmdungsmerkmalen in front view, and Fig. 2, the coupling piece of FIG. 1 in side view.
• the coupling piece shown has an upper coupling projection 10 and a lower coupling projection 1 1.
• a stop plate 12 is arranged, which simultaneously forms a parting plane between two stacked containers (not shown).
• the bottom of the stop plate 12 rests on the top of the upper corner fitting of the lower container, while the bottom of the lower corner fitting of the upper container is on the top of the stop plate 12.
• the upper coupling projection 10 has above the stop plate 12 a
• Shank 13 in turn, on its side facing away from the stop plate 12 carries a head 14.
• Der Schaft 14 ist mit dem Schenkel 13sky.
• the head 14 is on both sides on the shaft 13, thus forming locking projections 15 and 16.
• the lower coupling projection 1 1 also includes a shaft 17 to the
• Stop plate 12 at.
• the shaft 1 7 has on one side a perpendicular to the stop plate 12 extending front wall 18.
• At the front wall 18 opposite side of the shaft 17 has an insertion bevel 19, which merges at its end facing the stop plate 12 in a chamfer 20.
• This chamfer 20 corresponds to a chamfer on the slot of the corner fitting and rests with coupled coupling piece on this chamfer.
• the chamfer 20 could therefore also be regarded as part of the stop plate 12, in particular if the stop plate 12, as explained above, is formed only as a bead.
• the insertion bevel 19 is at its end facing away from the stop plate 12 in an arc-like manner in a rear wall 21, which is also arranged perpendicular to the stop plate 12.
• the lower coupling projection 1 1 also has a coupling nose 22, which is opposite to the rear wall 21.
• the coupling nose 22 is arranged laterally with respect to a longitudinal axis of the two containers to be coupled together.
• the coupling nose 22 On its upper side, the coupling nose 22 has an obliquely outwardly sloping shoulder 23.
• a Ein Industrieskegel 24 is disposed on the underside of the coupling nose 22.
• the width b of the coupling nose 22, ie a distance of a free edge 25 of the coupling nose 22 to the rear wall 21, is at most as wide as the width of the slot into which the lower coupling projection 1 1 engages. In that regard, at least the lower coupling projection 1 1 still substantially corresponds to the fully automatic twistlock according to DE 102 38 895 AI.
• the coupling piece according to the present exemplary embodiment has a groove-like recess 26 in the rear wall 21.
• the recess 26 extends over the entire length of the lower coupling projection 11 or the rear wall 21 and has a base 27 running parallel to the rear wall 21.
• the groove 26 On its side facing the upper coupling projection 10 or the stop plate 12, the groove 26 is bounded by an oblique shoulder 29 by an insertion bevel 28 and on its side facing away from the insertion bevel 28, ie away from the upper coupling projection 10 or the stop plate 12 ,
• the groove 26 thus has the shape of a trapezoid, wherein the angle of the insertion oblique 28 on the one hand and the oblique shoulder 29 on the other hand against the rear wall 21 need not be equal. Rather, it can be clearly seen in FIG. 1 that the insertion bevel 28 is steeper, namely has an angle of approximately 135 °, than the oblique shoulder 29, which has an angle a 2 9 of approximately 110 ° to the rear wall 21.
• the oblique shoulder 29 is not as steep as the oblique shoulder 23 of the coupling nose 22.
• the recess 26 bounding oblique shoulder 29 is aligned to a lower inner surface 30 of a recessed grip 3 1, which in Fig. 1 as a hidden Edge is shown with a dashed line.
• an angle a 23 of the oblique shoulder 23 of the coupling nose 22 to the vertical, ie to the front wall 18, greater than or equal to the angle a 2 9 of the recess 26 bounding oblique shoulder 29 to the rear wall 21 is.
• a further nose 32 is formed, the top of which forms the recess 26 bounding oblique shoulder 29. With this additional nose 32, the coupling piece can if necessary chop behind an edge on the upper slot of the associated corner fitting.
• the locking projections 15, 16 of the head 14 of the upper Kupplungsvor- jump 10 have lower, the stop plate 12 facing bearing surfaces 33 and 34, respectively.
• the bearing surface 34 of the locking projection 16, which is arranged above the locking lug 22, is closer to the upper side of the stop plate 12 (parting plane between the stacked containers), ie lower, arranged as the bearing surface 33 of the opposite locking projection 15th
