Definitions

  • ABSTRACT Apparatus for releasably locking large ocean-type vertically stacked cargo containers to each other.
  • a body is disposed between the containers, spaces the containers apart and is fitted with a cone that can be rotated from an open position into a locked position in which the cone engages an undercut in corner fittings of the container by actuating a handle that protrudes horizontally through a slot-like opening in a side of the body.
  • the body is also fitted with means to secure it to a corner fitting of the lower container at least while the cone locks the upper container to the body.
  • Container shipping particularly via ocean ships, becomes increasingly important as a result of the economics that can be achieved thereby.
  • the containers ranging insize from to 40 feet in length, 8 feet in both width and height are stacked one on top of the other.
  • Container alignment and positioning cones are inserted in container corner fittings and precisely align each container with the one below it as the stacks are built to their full height.
  • the present invention provides a container interlock that canbe used on all types of ocean or land going, large shipping containers to interlock the containers in a stack and to lock the lowermost container to a base even though adjacent container stacks may be separated by only an inch or less.
  • a central member including fixed oblong upper and lower protrusions and an intermediate body for supporting the container.
  • the body has a side opening disposed between the protrusions.
  • Aligned, substantially cylindrical apertures are in ends of the protrusions and have aligned cutbacks.
  • a locking cone is disposed above the upper protrusion and has a base that is complementary to a cross section of the upper protrusion.
  • a shaft depends from the base through the apertures, past an end of the lower protrusion and has a diameter complementary to that of the cylindrical apertures.
  • a flange extends laterally from the shaft and is disposed below the lower protrusion.
  • a handle is secured to the shaft and extends laterally therefrom past the open side for rotating the shaft and the cone about the axis of the apertures from an unlocked position in which the base is aligned with the upper protrusion to a locked position in which the base is offset with respect to the upper protrusion so that the cone is disposed within the undercut when the upper protrusion extends into the opening.
  • the container is thereby locked to the body.
  • Means is further provided for releasably securing the downwardly extending protrusion to the fitting of a lower container or a base against vertical movement.
  • the body separates the containers vertically by one or two inches, which is readily accepted since a slight increase in the overall container stack height does not adversely affect the capacity of the vessel.
  • the movable container interlocking cone is actuated with a handle disposed at the narrow side of the container. There is a substantial distance between the narrow end faces of the container stacks to provide clearance for the actuating handle and access for operating it.
  • the container interlock of the present invention is rugged, simple in construction and therefore of low cost. It performs the necessary container aligning func tion to facilitate container stacking by providing the rotatable cone.
  • the cone doubles as a container interlock after the top container has been positioned. I-Ieretofore necessary tedious hand work, inserting pins in inaccessible places and at hazardous heights and significant costs are thereby eliminated.
  • the present invention increases the economics of todays containerized shipping.
  • FIG. 1 is a perspective view of two vertically stacked containers interconnected with the container lock of the present invention
  • FIG. 2 is a cross-sectional, side elevational view of the container lock of the present invention
  • FIG. 3 is a cross-sectional, front elevational view of the container lock of FIG. 2;
  • FIG. 4 is a plan view of the container lock in its unlocked position
  • FIG. 5 is a plan view similar to FIG. 4 but shows the lock in its locked position
  • FIG. 6 is a bottom end view of the container lock of the present invention.
  • FIG. 7 is a plan view of the main body of the container lock with the alignment and locking cone removed;
  • FIG. 8 is a fragmentary, front elevational view ofthe container lock illustrated in FIG. 4;
  • FIG. 9 is a fragmentary bottom end view of the container lock and illustrates the position of flanges securing the cone to the main body when the cone is in its unlocked psoition shown in FIG. 4;
  • FIG. 10 is a fragmentary view similar to FIG. 9 but illustrates the position of the flanges when the cone is in its locked position (shown in FIG. 5).
  • a plurality of cargo shipping and storage containers 10 are placed on top of each other in a stack 12.
  • the containers have the usual dimensions, that is, an 8X8 foot cross section and have lengths of between 10 to 40 feet.
  • the containers rest on a support 14 of a container vessel 16 or the like.
  • Each container includes upper and lower corner fittings 18 which have vertically oriented, oblong apertures 20, that is, apertures having parallel sides 21 and curved ends 22.
  • An upright container mounting device 24 connects each adjacent set of corner fittings.
  • a lower half 26 of each device is secured to the lower container or the floor and an upper half 28 aligns the adjacent upper container with respect to the lower one and secures the two against relative horizontal movement.
  • the present invention provides locking means 30 for securing the containers to each other against relative vertical movements.
  • mounting device 24 is defined by a central body 32 which has upwardly and downwardly facing flat and parallel faces 34 and 36, respectively.
  • An upper protrusion 38 has an outline complementary to that of oblong corner fitting opening 20 and terminates in a flat upper end 40.
  • a lower protrusion or plug 42 depends downwardly from lower body face 36 in axial alignment with upper protrusion 38 and has a generally rectangular cross section that is defined by two sets of diagonally opposed, parallel side portions 44 and 46.
  • the first set 44 is parallel to sides 48 of upper protrusion 38 and second set 46 is inclined with respect to the first set by an angle of at least about 30 and preferably about 45.
  • a flange member 50 defining the lowermost end of plug 42 projects outwardly from the first parallel side portions 44 in continuation of and preferably parallel to the second side portion set.
  • the body 32 and upper and lower protrusions 38 and 42 are preferably heavy walled castings or the like and are hollow.
  • the body itself includes a vertical sidewall 52 which extends over three sides thereof and terminates short of the fourth side to define an open side or elongate slot 54 providing access from the exterior of the block to its interior.
  • the slot faces in the direction of the long axis of the cross section of upper protrusion 38 as best seen in FIG. 8.
  • Upper protrusion end 40 and a lower protrusion end 56 include aligned cylindrical apertures 58 which have cutbacks 60 for purposes more fully described hereinafter.
  • a container aligning and locking member 62 is defined by a cone 64 and a shaft 66 integrally constructed with the cone which depends downwardly from a cone base 68.
  • the cone base has an outline complementary to, that is which is the same as, the cross section of upper protrusion 38.
  • Shaft 66 is journalled in apertures 58.
  • a lower end 70 of the shaft includes a pair of opposite transversely extending flanges 70 (see FIGS. 9 and which are dimensioned so that they can pass through cutbacks 60 of cylindrical apertures 58.
  • An intermediate portion of the shaft mounts a horizontal handle 72 which extends outwardly through and past body slot 54.
  • the handle can be grasped on the exterior of the body and rotated from one end 74 to another end 76 of the slot.
  • cone 64 can be rotated from a position in which it is aligned with upper protrusion 38 (shown in FIG. 4) through an angle of preferably 90 into a position in which it is perpendicular to the upper protrusion (shown in FIG. 5).
  • the handle is preferably permanently secured to shaft 66 as by first inserting the shaft through apertures 58 and then welding the handle end to a suitable bore in the shaft.
  • the handle can be threadably or otherwise demountably attached to the shaft.
  • flanges 70 on the lower end of shaft 66 are angularly offset relative to cone 64 by several degrees, say by to about 30.
  • the angular offset of the flanges is in the direction of rotational movement of the cone from the aligned to the perpendicular positions (shown in FIGs. 4 and 5).
  • the flanges are spaced from cone base 68 a distance slightly greater than the spacing between ends 40 and 56 of the upper and lower protrusions, respectively, so that the flanges are disposed below the lower end of the lower protrusion.
  • the flanges are always offset from aperture cutbacks 60.
  • cone 64 and shaft 66 are effectively locked to body 32 and protrusions 38 and 42.
  • Block 24 is placed on top of an upper corner fitting l8 ofa container (or ofa like fitting mounted to ship floor 14) and rotated about a vertical axis to align plug sides 46 with oblong aperture 20 in the corner fitting.
  • body 32 is rotated with respect to sides of the container by the same angle as the angular offset between lower plug sides 44 and 46.
  • the block is now lowered into the corner fitting until lower body face 36 rests on top of the corner fitting.
  • the first set of plug sides 44 is angularly inclined with respect to straight sides 21 of the corner fitting opening and does not obstruct the lowering of the block.
  • the block is rotated until the second set 44 of parallel lower plug sides engage sides 21 of the corner fitting aperture. This locks the block against vertical or transverse motion to the lower corner fitting and aligns body 32 with the fitting.
  • the handle 72 is at righthand slot end 76 as shown in FIG. 4 to align the cone with the upper protrusion. Thereafter the next container is lowered. Cone 64 facilitates the engagement of the oblong aperture in the lower comer fitting and continued downward motion of the container automatically aligns the container with upper protrusion 38 until the lower face of the corner fitting on the upper container rests on upper face 34 of body 32. In this position, upper end surface 40 of protrusion 38 is substantially aligned, that is, it is just slightly above a flat surface 78 of corner fitting 80 where aperture 20 terminates. That flat surface defines a recessed portion on undercut 18 of the corner fitting. An operator now moves handle 72 from righthand corner 76 to lefthand corner 74 of body slot 54.
  • Shaft 66 and cone 64 are thereby rotated to position the cone perpendicular with respect to upper protrusion 38 and place those portions of the cone which extend beyond the outline of the upper protrusion in corner fitting undercut 80. Since shaft 66 is secured against axial movements by flanges 70 on its lower end, the upper container is now secured against vertical movement relative to body 32 and, since the body is secured against vertical movement to the lower corner fitting, the upper container is secured against vertical movements to the lower container. In this manner, all relative motions between the containers is prevented.
  • interlock handle 70 is constructed of a relatively resilient material, such as steel bar, and positioned closely adjacent a lower side 82 of slot 54.
  • a pair of locking blocks 84 are positioned in the normal path of the handle as it moves between slot ends 74 and 76 adjacent each slot end but spaced therefrom so that vertical walls of the blocks define handle receiving spaces 86.
  • Sides 88 of the blocks generally facing toward each other are sloped from lower slot side 82 to the uppermost part of the block.
