Abstract

When the same coupling piece (10) with driving means is used for locking 20 ' containers placed in the storage space of a 40 ' container, it must be ensured that the narrow joint (13) between the opposite ends (12) of 20 ' containers (11) located one in front of the other has a distance sufficient for the driving end (47) of the driving means, which driving end (47) protrudes from the housing (16) of the coupling piece (10) to be mounted into the narrow joint (13). To meet the above need, a coupling element (10) according to the invention has a docking element (19), the docking element (19) projecting by a length of about half the width of the joint between the heads (12) with respect to the opposite ends (12) of the successive 20' containers (11). The projecting parts of the abutment members (19) of adjacent coupling members (10) thus abut against each other in the region of the joints (13) between successive 20' containers (11), there being a joint (13) of sufficient width to accommodate the drive end (47) of the drive means of the coupling member (10) and the knob (48), even in the case of very high stacks of containers.

Description

Connectors for connecting containers

The invention relates to a connection for connecting containers according to the preamble of claim 1 , 6 , 9 or 13 .

Connections of the type described herein are used to connect containers on board ships. When connecting a 20' container loaded in a storage space for a 40' container, certain features will arise. At this time, in each case, two 20' containers are loaded one after the other, that is to say with opposite ends, in the storage space for the 40' container. To do this, two consecutive 20' containers must have the same external dimensions as the 40' container. This leaves only a very narrow gap between the opposite ends of two consecutive 20' containers. This requires special purpose connectors to stack the 20' containers one on top of the other, or specially constructed connectors.

It is known to use different connectors to connect 20' containers in the storage space of 40' containers, where special connectors (called intermediate locks) are used for narrow joints between adjacent ends of 20' containers within the area.

Furthermore, it is known to connect successive 20' containers in the storage space of 40' containers by the same connection with operating means. In this case, the connectors of special construction can be arranged between the opposite ends of the 20' container. However, these connections can be modified to suit all requirements.

The invention is therefore based on the object of providing a connection, especially for the use mentioned in the opening paragraph, which is simpler to handle and which has an improved connection compared to known connections of this type. function.

To achieve this object, the connecting piece has the features of claim 1 . The butt pieces protrude relative to the ends of the containers, which ensures that the joint between the opposite ends of the 20' containers placed one after the other in the storage space of the 40' container is always large enough and There is space available for the drive means projecting laterally to the outside of the connection in the direction of the joint between the ends of the 20' container. It also ensures that, with the lower corner joint of the topmost container connected, the upper corner joint of the topmost container is at such a distance that another container can be placed on top of the topmost container and at the joint There is also enough space for their drives.

The butt joint is preferably designed such that it projects relative to the ends of the containers to be joined by approximately half the width of the junction between the opposite ends of adjacent containers. The male abutments of the opposing connectors then bridge substantially the entire junction between the adjacent ends of the container. The result is that when 20' containers are stacked consecutively on top of each other, the joints between the containers are always approximately equal in width, especially when a 20' container is placed in the storage space of a 40' container between two consecutive The width of the space formed between 20' containers. This joint is typically about 76 mm or 3 inches.

The containers are not held apart merely by the abutments protruding into the joint, but they are also supported in such a way that they do not twist, or visibly twist, under expansion.

The part of the butt joint that protrudes into the joint and protrudes relative to the end of the container is inclined towards its free end, particularly preferably in such a way that when the container is lowered so as to be placed on the When the container is on the container, the protruding part of the mating part that is already located between two adjacent containers and belongs to the other connecting part slides downwards, and in the process, the mating part of the connecting part on the opposite end of the adjacent container The projections give the normal width of the joint between the containers, the opposite, projecting transverse edges on the abutment of the connection between the containers following each other at the mutually bearing ends.

In order to achieve the above object, a further connecting piece has the features of claim 6 . The or each notch is able to accommodate the portion of the drive means projecting from the connecting element into the joint between two adjacent containers despite local conflicts between the opposed transverse edges of the protruding portions of the docking element.

Preferably, the recesses are arranged eccentrically in the region of the abutment projecting relative to the container end. This accommodates the portion of the drive that protrudes out of the housings of the two connectors and is supported in the area of the joint between the opposite ends of the two 20' containers so that they are positioned one above the other in the joint. Besides, this eliminates the risk of collisions between the drives of adjacent connectors.

In order to achieve the object stated at the outset, a further connecting part has the features of claim 9 . The locking slide, mounted to move longitudinally in the coupling projection of the link, is able to move laterally with respect to the longitudinal axis, which means that when the locking slide is in its locked position, it can move sideways while maintaining said position . This enables the hook-in joint of a coupling rod or the like to be hooked through a transverse slot in the corner joint and past the locking slide in which the connection projection with the locking slide is located.

In order to achieve the object stated at the outset, a further connecting part has the features of claim 13 . The means for moving the connecting piece relative to at least one corner joint of the container ensures that the connecting piece moves directly towards the corresponding end of the container after being pre-locked under the corner joint of the upper container, so that the connecting piece enters the corresponding corner joint A relative position which ensures an automatic and reliable connection between the connecting piece and the underlying container. In particular, moving the link in the lower corner joint ensures that, in the case of a link with a drive, the drive is located to the side, next to the corner joint, and when the upper container on which the link is hung is lowered between the lower container When put on, the connecting piece does not enter between the containers to be connected.

Preferably, the device is supported in a corner joint of the container towards which it will move.

At this time, the device simultaneously acts to prevent the connector from moving out of the lower corner joint of the upper container, because the device, which is at least partially inserted into the lower corner joint, prevents the connector from turning and leaving under the lower corner joint of the upper container pre-locked position.

Preferably, the device is designed as a pawl, which is pivotable, the pivot axis of which extends horizontally and transversely with respect to the direction in which the pawl moves the connecting piece relative to the container corner joint (direction of movement). The pawl is preferably pivotable in a vertical plane extending longitudinally with respect to the direction of movement of the link. The pawl is mounted such that it can pivot in a vertical plane along the direction of movement of the connecting piece, which enables the pawl to automatically enter the corresponding slot of the corner joint after the connecting piece is locked under the lower corner joint of the upper container. in the slot. Thus, there is no need to actuate the pawl to initiate pivotal movement of the pawl. Furthermore, during the automatic pivoting of the pawl within the slot of the corner joint, the link moves under the corner joint. At least a portion of the detent is inserted into the slot of the corner fitting while also preventing the connector from rotating under the corner fitting to an extent that the connector can be disengaged from the corner fitting.

To remove the connector from the lower corner fitting, it is only necessary to push the connector back on the lower corner fitting until the pawl pivots back so that it disengages from the slot. The connecting piece can then be rotated under the corner joint and withdrawn from the corner joint.

Wherein, the connecting piece 10 shown in the figure is suitable for connecting the 20' container in the storage space of the 40' container. In each case, the two 20' containers 11 indicated by the dot-dash line part in the figure are arranged one behind the other so that there is a narrow joint between the two opposite ends 12 of the two 20' containers 11. At 13, this narrow joint 13 is typically about 76 mm or 3 inches.

20' containers 11 stacked one on top of the other are connected to each other at their corner joints 14, 15, in each case in particular at the upper corner joint 14 of the lower container 11 and the lower corner joint 15 of the upper container 11 connected to each other. The corner joints 14 and 15 at both sides of the junction 13 of the opposite ends 12 of the container 11 and 20' the outboard ends of the container 11 (not shown) are connected to each other by means of the connector 10 of the same construction.

The connector 10 has a two-piece housing 16 . The shell 16 is divided centrally by a vertical parting plane 17 which extends through the two shell halves of symmetrical design and in particular in a plane perpendicular to the respective end 12 of the container 11 . The two housing halves are connected to each other by screws 18 in order to form the housing 16 .

On its outer profile, the shell 16 has a butt joint 19 that extends along a horizontal plane and is located between two 20' containers 11 that are to be connected to each other, one above the other, and in particular at corner joints Between 14 and 15. Starting from the mating piece 19, a connecting projection extends upwards, and a connecting projection 21 extends downwards. They have different structures. The upper connection boss 20 has an approximately rectangular central portion 22 which extends through a lower slot 23 on the lower corner joint 15 of the upper 20' container 11. The dimensions of the rectangular central portion are slightly smaller than the width of the slot 23 . Due to the rectangular cross-section, the connecting element 10 can move longitudinally inside the slot 23, in particular towards and away from the end 12 of the respective 20' container 11. Above the central part 22, the upper connecting projection 20 has a transverse latch 24 which is connected to the projection 20 in one part and which is located on the opposite side of the central part 22 with respect to the parting face 17. Protrudes laterally outward. When the connector 10 is in the locked state, the outer parts of the transverse latches 24 protrude relative to the central part 22 , cooperating in certain areas behind the parallel long sides of the slots 23 , especially from the inside of the corner joint 15 .

The lower connection projection 21 has a central portion which substantially fills the upper slot 26 on the upper corner joint 14 of the lower 20' container 11. This central portion 25 extends into a protrusion 27 whose width is substantially equal to the width of the central portion 25 and thus to the width of the slot 26 . Viewed from the side ( FIG. 4 ), the projection 27 tapers towards the free end of the lower connection projection 21 .

An elongated locking slider 28 is mounted so as to be movable in the lower attachment lug 21 . The vertical center plane of the locking slide 28 is on the vertical dividing face 17 between the two halves of the housing 16 . The longitudinal center axis of the locking slide 28 extends at a small angle relative to the horizontal, in particular such that one end of the locking slide 28 can be moved outside the lower connecting projection 21 in order to form the locking projection 30 and it is slightly It is inclined downward, that is to say, when the locking slider 28 protrudes from the lower connection protrusion 21 , the locking protrusion 30 is away from the bottom surface of the mating member 19 .

A protruding stopper 31 is arranged on the bottom surface of the locking slider 28 , the protruding stopper 31 being located inside the lower connecting protrusion 21 . A stop 31 is located in an elongated slot 32 in the bottom surface of a clearance 33 for receiving the locking slider 28 in the lower coupling projection 21 . The size of the groove 32 is such that it limits the movement of the locking slider 28 in the lower connecting protrusion 21, especially in such a way that, on the one hand, the locking slider 28 can extend from the lower connecting protrusion 21. To such an extent that the locking projection 30 protrudes by a sufficient length relative to the lower connecting projection 21, while on the other hand, in the fully retracted state of the locking slider 28, the locking projection 30 is actually completely located on the lower connecting projection 21. Inside the protrusion 21 .

On the rear side 34 opposite to the direction of the locking projection 30 , the locking slide 28 has a blind hole 35 . A blind hole 36 is also arranged in the lower connecting projection 21 , starting from the rear side 37 of the recess 33 . In the blind holes 35 , 36 , the opposite ends of the compression spring 38 are supported between the lower connection projection 21 and the locking slide 28 . By compressing the spring 38 , the locking slide 28 is pressed into its locking position, while the locking projection 30 points maximally out of the lower connection projection 21 .

A free space 39 is also arranged in the housing 16 above the cutout 33 , which is connected to the cutout. The parting surface 17 runs centrally through this free space 39 , so that each half of the free space 39 is formed by one half of the two shell halves 16 in each case. A lever 40 with two arms is arranged in this free space 39 . A pivot 41 extends centrally through the lever 40 , which pivot 41 extends perpendicularly to the parting plane 17 and thus across the free space 39 . The lever 40 is pivotable about a pivot 41 in opposite directions.

A downwardly pointing lever arm 44 of the lever 40 protrudes into a corresponding recess 43 of the locking slide 28 . The opposing lever arm 42 on the lever 40 is connected to drive means which in the illustrated embodiment is a cable 45 . The cable 45 is led out of the transverse wall 46 of the docking part 19, directed towards the end 12 of the 20' container 11, through a guide hole 55 extending centrally through the parting surface 17 and the docking part 19 in the direction level. In order to form the drive means, the cable 45 protrudes with a drive end 47 which projects laterally beyond the transverse wall 46 of the counter piece 19 . The free part of the drive end 47 is bound to the handle, in particular the knob 48 . When the cable 45 of the driver is pulled out of the docking member 19 by using the knob 48, the lever 40 pivots clockwise (as shown in FIG. Instead, the locking slide 28 is drawn into the housing 16 , in particular to such an extent that the locking projection 30 disappears substantially completely in the lower connecting projection 21 .

The locking slide 28 is mounted in the recess 33 of the lower connecting lug 21 such that it can move transversely with respect to its longitudinal center axis 29 . This mobility of the locking slide 28 in the recess 33 of the lower connecting lug 21 is due to the fact that the recess 33 is much wider than the locking slide 28 ( FIG. 7 ). Thus, the locking slide 28 can be tilted in the clearance 33, so that the locking projection 30 protruding outside the lower connection projection 21 can move laterally back and forth outside the connection projection 21, in particular relative to it in the lower connection. The movement track in the protrusion 21 moves laterally. In the upper corner joint 14 of the lower 20' container 11, the magnitude of this lateral mobility of the locking protrusion 30 protruding to the outside of the connecting protrusion is such that the hook-in joint 49 of the coupling rod 50 can be directed towards the 20' The end 12 of the container 11 passes through the vertical slot 51 and can be pressed against the contact surface 52 of the edge portion of the slot 11 inside the corner joint 14 ( FIGS. 6 and 7 ). Typically, a lateral mobility of the locking projection 30 of about 10 mm is sufficient for this purpose. This makes in the case of 20' containers 11 one above the other and connected together by the connector 10, although the locking protrusion 30 of the locking slider 28 protrudes to the lower connecting protrusion 21 in the direction of the slot 51 Externally, it is also possible to insert the hook-in joint 49 of the coupling rod 50 through the slot 51 into the corner joint 14 and tilt it in such a way that the coupling rod 50 can be locked by the hook-in joint 49 in the corner joint 14 .

The docking piece 19 is designed in a specific form. It extends towards the driving end 47 of the cable 45, in particular to such an extent that it protrudes relative to the end 12 of the 20' container 11 (one above the other) to be connected (Figs. 1 to 3 ). The abutment 19 is preferably projected relative to the end 12 of the 20' container 11 or to the vertical surface of the corner joints 14, 15 towards the end 12 so as to protrude to such an extent into the adjacent 20' In the joint 13 between containers 11 , the transverse wall 46 of each docking member 19 protrudes relative to the end 12 or corner joint 14 , 15 by half the width of the joint 13 between containers 11 typically at 20' , which is about 38mm or 1.5 inches. The result is that each abutment 19 protrudes to the center of the joint 13 . In the case of 20' containers 11 stacked one on top of the other, in the region of the opposite ends 12 of said containers, the transverse walls 46 of the male abutments 19 of the opposing connectors 10 generally abut against each other. Thus, the distance between the opposite ends 12 of 20' containers 11 stacked one above the other is always kept constant due to the abutment 19 projecting into the joint 13, making the normal width of the joint 13 about 76mm or 3 inches. At the same time, the containers 11 of adjacent container stacks are supported on the adjacent connectors 10, since the loads experienced by the containers 11 in the expanded condition are limited.

The opposite side of the transverse wall 46 of the abutment 19 projecting with respect to the opposite end 12 of the container 11 is inclined, ie provided with a sliding surface 53 . This sliding surface 53 ensures that when a second 20' container 11 is placed on top of the container 11 below it, if the distance between the opposite ends 12 of the 20' container 11 is less than the normal width of the joint 13, then the abutment 19 The raised areas are able to slide over each other. Thus, the upper 20' container 11 to be placed on top of the lower 20' container 11 is guided by the abutment 19 protruding into the joint 13, in particular through the joint 13 having the required suitable width.

The counter piece 19 has a recess 54 which extends at least in a region which protrudes relative to the corner joints 14 and 15 (protrudes into the joint 13 ). The notch 54 is located on the side next to the vertical longitudinal center axis of the connecting piece through which the parting face 17 of the two shell halves 16 extends ( FIG. 3 ). Furthermore, this notch 54 extends to the area where the cable 45 protrudes from the transverse wall 46 of the docking piece 19 . The position of the point at which the cable 45 protrudes from the abutment 19 is also eccentric with respect to the parting surface 17 , that is to say on the side of the parting surface 17 opposite the main part of the recess 54 . The guide opening 55 for the cable 45 (in plan view of the connecting part 10 ) therefore has a bending process in its end region 56 ( FIG. 3 ) which is open to the outside of the transverse wall 46 .

The notch 54 is in that part of the abutment 19 that protrudes into the joint 13 and is connected to the curved end region 56 of the guide hole 55, which means that between the adjacent ends 12 of the continuous 20' container 11 In the region of the joint 13 between the adjacent connectors 10 rotated by 180°, the driving ends 47 of the cables 45 protruding from the outside of the connector 10 and having a spherical handle 48 pass through each other and are introduced into the recesses of the adjacent connectors 10 54, a portion of the knob 48 projects into a slot 51 disposed at the end 12 of the 20' container 11 and in the corner joints 14 and 15 (Figs. 2 and 3). In this way, it is ensured that the drive end 47 and the knob 48 of the drive means for the coupling 10 fit without damage in the narrow joint 13 between the opposite ends 12 of the continuous 20' container 11. When loading the 20' container 11, through the proper sequence, such a state will be formed that the drive end 47 of one connector 10 with the knob 48 faces downwards and extends into the upper corner joint 14 of the lower 20' container 11 At the same time, the driving end 47 with the ball handle 48 of the connector 10 for connecting the adjacent 20' container faces upward and extends into the end in the lower corner joint 15 of the upper 20' container 11 inside slot 51 (Fig. 2). In this way, collisions between the drive end 47 and the knob 48 of the adjacent connecting piece 10 within the narrow joint 13 can be eliminated.

Each connecting piece 10 also has such means, which in particular serve to make the connecting piece 10 relative to the lower corner joint 15 of the upper 20' container 11 in the direction of the joint 13 or along the 20' container pointing towards the joint 13 11 to move in the direction of end 12. In addition, the device also acts as a safety device against rotation of the connection piece 10 under the corner joint 15, and thus also serves as a safety mechanism against disengagement of the connection piece 10 pre-locked under the lower corner joint 15 of the 20' container 11 . Thus, the device has a dual role.

In the illustrated embodiment, this means is designed as a pivotable pawl 57 . The pawl 57 is pivotable in a vertical plane, particularly preferably in the parting plane 17 . To this end, the pawl 57 is rotatably mounted on a horizontal pivot 58 extending across the parting face 17 of the housing 16 . Arranged on the pivot 58 is a helical spring 59 , which is supported at one end 60 in the housing 16 and at the opposite end 61 on the pawl 57 . This helical spring 59 engages the pawl 57 in such a way that it pivots the pawl 57 in the counterclockwise direction relative to the connection piece 10 shown in FIG. 4 .

The pawl 57 is designed such that when the coil spring 59 is prestressed, the upper long side 62 of the pawl 57 is approximately flush with the upper side 63 of the mating part 19 , or it is slightly lower than the upper side 63 . In this case, one end 64 of the pawl 57 points in the direction of the knob 48 of the drive mechanism of the connecting piece 10 . When the pawl 57 is pivoted upwards due to the helical spring 59 , the pawl's head 64 protrudes forward relative to the upper side 63 of the abutment 19 ( FIG. 9 ).

To pre-lock the connector 10 under the lower corner joint 15 of the upper 20' container 11, the long side 62 of the pawl 57 presses under the bottom wall 65 of the corner joint 15 and surrounds the slot 23. At this time, the pawl 57 coincides with the upper side 63 of the docking member 19 ( FIG. 8 ). After the connector 10 is inserted into the slot 23 of the corner joint 15 from below and rotated, the knob 48 points to the end 12 of the 20' container 11, and the projection on the transverse latch 24 of the upper connection projection 20 is released from the slot. The inside of the slot 23 is inserted behind the corner joint 15 . Thus, the connection piece 10 is partially pre-locked under the corner joint 15 . Then, when the connector 10 is properly moved again slightly towards the end 12 of the 20' container 11 relative to the corner joint 15, the pawl 57 is pivoted by the prestressed coil spring 59 (in the reverse direction in FIG. 8 ). clockwise). At the same time, the head 64 of the pawl automatically moves out of alignment with the upper side 63 of the counter piece 19 and bears on the inside of the slot 26 of the corner joint 15 . Then, when it pivots further, the detent 57 moves the connection piece 10 under the corner joint 15 in the direction of the end 12 of the 20' container 11, in particular to such an extent that the center of the upper connection projection 20 Portion 22 is located approximately in front of the end of slot 23 towards tip 12 ( FIG. 9 ). In this position of the connecting piece 10, the protruding portion of the docking piece 19 is located in front of the end 12 of the container 11 at 20'. The same applies to the drive end 47 of the drive with the knob 48 . This ensures that when a 20' container 11 with connectors 10 pre-locked under the lower corner joint 15 is placed on top of the lower 20' container 11, neither the drive end 47 nor the knob 48 will clamp between the two containers 11 to be connected. between. Furthermore, the connection piece 10 is moved in the direction of the end 12 by means of the pawl 57 prestressed by the helical spring 59 , which ensures such pre-locking of the connection piece 10 below the lower corner joint 15 of the upper 20 ′ container 11 In this position, it is possible to reliably and automatically lock the connector 10 to the underlying 20' container 11.

When the connector 10 moves under the corner joint 15, the end 64 of the pawl 57 enters the slot 23, which ensures that the connector 10 below the corner joint 15 will not rotate to such an extent that the upper connection protrusion 20 The projections on the transverse latches 24 are disengaged from the corner joints 15, and the connectors 10 will not come off the lower corner joints 15 of the upper container until the upper container 11 is placed on the lower container 11.

The connector 10 is released from the lower corner joint 14 of the upper container 11 by being pushed away at least from the end 12 . During this process, the head 64 of the pawl automatically pivots away from the slot 23 and maintains the pivoted back position below the bottom wall 65 of the corner joint 15 . Only the connection piece 10 under the upper container 11 can be rotated 90° (about the vertical axis), so that the transverse latch 24 of the upper connection projection 20 is disengaged from the corner joint 15 and the connection piece 10 can be pulled down and out of the way Corner joint 15.
