Abstract

The hooking fitting (10) holds a lashing rod (14) in the corner fitting (28) of a container (20). The fitting has a finger which fits in an eye (33) of the corner fitting, more precisely in a gap (34) between the hooking projection (32) of a connecting fitting (30) for two containers (20, 26) one above the other, and the first wall (35) of the eye.

Description

The invention relates to a hook fitting for hooking a lashing rod into one Corner fitting of a container. The invention further relates to a lashing device for Lashing a container on a ship deck with a lashing rod and one on of the lashing rod attached to hook the lashing rod into a corner fitting of the container.

Such a hook fitting and such a lashing device are in the DE 30 50 557 C2 discloses. Furthermore, a lashing rod with such Hook fitting by the applicant under the type designations R-KS, R-KV, R-ES or R-EL are sold and are in the main catalog of the applicant from the 1999 "SEC going for the long run".

On container ships, 20-foot containers are usually packaged by several containers on top of and next to each other as well as two containers transported one after the other. Two 20-foot containers arranged one behind the other are usually at a distance (loading gap) of 3 inches with the narrow end faces to each other, i.e. with the door or front sides or the Backs arranged to each other. In the technical language is usually from a "3" gap loading ". With this type of loading fittings are the Containers facing the loading gap are not accessible, so lashing equipment cannot be attached to these corner fittings. On top of each other arranged containers are usually through at all four corners suitable connection fittings connected to each other. For this purpose, serve Example of those still accessible in the loading position on the ship Semi-automatic corner fittings (Twistlocks), as used by the Applicant can be sold under the type designation TL-A or TL-GA. On the inaccessible corner fittings become fully automatic center fittings (Midocks), which the applicant uses under the type designation TL-ML distributes. These fittings (each a semi-automatic twist lock on the accessible corner fittings and a midlock each on the in the charging state on the Ship inaccessible corner fittings) are on the underside of one on the Container to be loaded into the four bottom corner fittings of a stevedore hooked and snap when you put the container on one already on the Ship container in its four upper corner fittings or in one Foundation on the ship deck automatically. When deleting the container the semi-automatic rotating fittings are released from the stevedore to the accessible corner fittings manually released so that they come out of the corner fittings of the lower container can slide out. When lifting the container the fully automatic center fittings slide out of the corner fittings of the lower one Containers out, the container is tilted slightly by lifting. The Turn fittings and the center fittings can then manually from the stevedore the corner fittings of the upper, unloaded container are removed.

In order to additionally secure the containers securely on the ship, they are attached to their accessible end faces additionally with lashing rods, in the technical language lashing called bars, lashed. The lashing rods are hooked into the accessible corner fittings of the containers hooked in and using a clamping device (Turnbuckle) in a lashing point welded onto the ship's deck hung and tensioned. The used on the accessible corner fittings Due to their design, twist locks allow both in the lashing rods can be attached to the lower and upper corner fittings can.

In the case of particularly heavy loads, it is sometimes necessary that the containers must be secured with lashing rods on both ends. Some Container ships therefore allow containers with both the "3" gap loading " as well as with a wider lashing gear between two in a row arranged containers can be transported. Due to the design of the However, it is only possible to fit the bottom locks Attach a lashing bar to the corner fittings of the containers. The top Corner fittings are occupied by the middle lock (Midlock), so that here the known hook fittings can not be hung. If you wanted to do this at this point, twist locks would also have to be used. However, this would mean that the ship could be equipped with midlocks as well as twist locks for these corner fittings would have to, since the lashings always stay with the ship and especially for the ship are designed. This would be correspondingly expensive and would just stow space for that claim unused connection fittings.

Proceeding from this, the invention is based on the problem of corner fittings and Training lashing of the type mentioned in such a way that they also in the upper corner fittings with a central lock (midlock) Containers can be hung.

To solve this problem, the corner fitting according to the invention is by a Finger that is in an eye of the hook fitting, namely in a gap between one Hooking nose of a connecting fitting for two superimposed ones Container and a first wall of the eye, engages, marked.

The corner fitting according to the invention is therefore designed so that it next to the Hooking nose of a connection fitting, specifically a center fitting (Midlock) can be hung in the corner fitting of the container. The Lashing bar can therefore also be used in the top corner fittings of the container with a Center lock (Midlock) are attached, so that the container is secure both on their upper and, as was previously customary, their lower Corner fittings can be lashed to both ends. In addition, by a vertical play through the gap between the Hooking nose of the connection fitting, i.e. the center fitting, and the Wall of the eye of the corner fitting is reduced, so that by the Connection fitting, i.e. the center fitting, the one above the other Containers are better connected to each other. The gap in which the finger intervenes, is required in the prior art so that the container or Center fitting automatically during deletion from the Corner fitting of the container underneath can slide out.

According to a development of the invention, the hook fitting has below the Fingers a nose, so that the hook fitting with the finger and the nose Hooking nose of the connecting fitting grips like a mouth. Both the Hook fitting as well as the connecting fitting, i.e. the center fitting (Midlock), are thereby in the corner fitting with even less play, that is with still more security anchored.

In particular, according to a constructional design, a The fillet can be arranged, the pivot point under tension on the lashing rod on a second wall of the Forms corner fitting for the hook fitting. This results in a Largest possible lever arm for a pressure force on the finger or its Securing nose so that the greatest possible holding force on the hook fitting, which the Hold the hook fitting in the corner fitting of the container, work.

The hook fitting already sits securely in the measure according to the invention Corner fitting of the container or in its eye. This is especially true if after finished lashing the lashing forces act on the hook fitting. So that Hook fitting also during lashing, if not yet final lashing forces act on the hook fitting, not from the corner fitting can fall out, the finger is at its free end with an additional Provide locking lug. However, this also provides for when the lashing is finished unfavorable sea conditions an additional securing of the cargo, i.e. the Containers. The hooking nose is preferably specific to the contour of the eye its first wall, adapted.

Furthermore, the corner fitting preferably has a contour through which it fits in a Working position on the left (the lashing bar runs from the left corner fitting of the Containers to the bottom right), right (the lashing rod runs from the right Corner fitting of the container to the bottom left) and straight (the lashing rod runs straight down from the corner fitting of the container) into the corner fitting of the Containers can be hung. Equally trained hook fittings can thus hooked into any working position on the deck of a ship and the container is lashed in this way. The stevedore need not pay attention to that certain working positions to use certain hooking fittings.

A further development of the invention provides that the finger on the side of Hooking fitting, in particular on the side of the securing lug of the finger Ear is arranged. This ear usually undercuts it as an elongated hole or oval trained eye of the corner fitting and thus forms an additional security against falling out in the lashed state. The container is also under adverse weather conditions at sea and maximum cargo weight lashed. It is particularly advantageous on both sides of the finger or the To provide a safety nose for each ear. One of the two ears is therefore in the Stop position to the left or right of the hook fitting so that it is the same Hook fitting can be used for both stop positions.

According to an embodiment of the invention, the finger of the hook fitting delimited by a hump from the main body of the hook fitting. The finger is even better at the contour of the eye of the container corner fitting customized.

One for use on board the ship and also special in forging technology favorable embodiment lies in a hook fitting on the finger opposite side of the main body a hook for hooking the Has hook fitting in the corner fitting. The corner fitting can be in this Case hooked into the corner fitting either with your finger or a hook become. The hook fitting, which on the hook side like a conventional one Hook fitting can be formed, can therefore be both for one with one Midlock as well as a container corner fitting with a twistlock universal are used, although of course the finger side to Hooking into a container corner fitting with a twist lock is suitable.

The lashing device according to the invention is characterized in that it is a Hook fitting with the features according to the invention and, if appropriate, their has advantageous further training.

The hook fitting 10 shown in FIG. 1 is in one piece, for example as Forged part made. It has a main body 11, in which approximately in the middle Eye 12 for a fastening bolt 13 (Fig. 3) is arranged. With the Fastening bolt 13, the corner fitting on a lashing rod 14 is pivotable attached, the fastening bolt 13 forming the pivot axis at the same time.

The hook fitting 10 also has a finger 15, which, as said, in one piece is connected to the main body 11. The finger 15 points at its free end a slightly hook-like upward curved locking lug 16. Below the Fingers 15 is arranged a nose 17, below which there is in turn one Cove 18 is located. The fillet 18 separates the nose 17 from one Stop pin 19. The stop pin 19 runs approximately perpendicular to the finger 15 and is directed downwards.

2 and 3 show the hooking fitting 10 in the working position. In the specific case a lower container 20, of which only the one normally finished here loaded ship inaccessible end face 21 is shown, directly on a Ship deck 22 lashed. For this purpose, the ship deck 22 has itself known raised foundations 23 on which the container with its lower Corner fittings 24 is placed. Via a rotating fitting 25, for example a Buttom Twistlock TL-BL or TL-BQ or a Fixed Base Twistlock TL-S or TL-GS of the applicant, the container 20 by its lower Corner fitting 24 lashed to the foundation 23.

On the container 20 lashed on the ship deck 22 in this way, a further, placed on the upper container 26, of which only the normally not accessible end face 27 is shown. The in the normally inaccessible End faces 21 and 27 arranged, inaccessible upper corner fittings 28th of the lower container 20 and lower corner fittings 29 of the upper container 26 are by a central fitting 30, in the present case a Midlock TL-ML Applicant, connected to each other as a connection fitting. Since already at Prior art, it is not shown in Figs. 2 and 3 that in the lower one Corner fitting 29 of the upper container 26 a lashing rod is attached. This engages with a hook fitting in a rear eye 31 of the corner fitting 29.

As can be clearly seen in FIGS. 2 and 3, a hooking nose 32 engages the Center fitting 30 in the rear eye 33 of the upper corner fitting 28 of the lower container 20 that hooking fittings according to the prior art here can no longer be attached.

The hook fitting 10 according to the invention reaches into the eye with its finger 15 33, namely in a gap 34 between a hooking lug 32 and a first one, top wall 35 of the eye 33. The hook fitting 10 can be so despite the Center fitting 30 or its hooking lug 32 in the upper corner fitting 28 be hung up.

As can also be seen in FIGS. 2 and 3, the hook fitting 10 engages with his finger 15 and nose 17 the hooked nose 32 mouth-like. As well as well it can be seen that the fillet 18 rests on an edge of one of the first walls 35 opposite lower wall 36.

The lashing rod 14, on which the hook fitting 10 is pivotally attached, is on their other end in a tensioning member 37, which in turn is in a forward 38, which is welded onto the ship deck 22, is hooked in, hooked. By Tensioning the tensioning member 37, lashing forces are transmitted to the lashing rod 14. These lashing forces cause the hooking fitting 10 to twist Counterclockwise according to the illustration shown in FIGS. 2 and 3. Pivot point the point of contact of the fillet 18 on the edge of the lower wall 36. The finger 15 thereby presses against the upper wall 25 of the eye 33, so that the hook fitting 10 securely in the upper corner fitting 28 of the container 20 is hooked.

As long as the lashing rod 14 with the hook fitting 10 is still loose in the upper Corner fitting 28 hangs, engages the locking lug 16, which for this purpose to the Contour of the upper wall 35 is adapted behind the upper wall 35 and also prevents the hook fitting 10 from falling out. But also after finished lashing, so when lashing forces on the lashing rod 14 and Hook fitting 10 act, forms the locking lug 16 even with the heaviest Additional protection against falling out.

Another embodiment of a hook fitting 10 according to the invention is shown in Fig. 4. A lashing device with this hooking fitting is shown in FIGS. 5 to 7. Since the hook fittings 10 according to FIGS. 1 and 4 correspond in some respects same here with the same reference numerals, so that to that extent reference is made to the above description.

In addition to the hooking fitting 10 according to FIG. 1, the hooking fitting 10 4 laterally on the finger 15, specifically laterally on the securing lug 16 Ear 39 on. As can be seen in FIG. 7, the securing lug is on both sides 16 one ear 39 each. Fig. 7 shows a straight position for the left Lashing rod 14 in which the hooking fitting 10 into the eye 33 of the corner fitting 28 can be hooked. This position also corresponds to the straight one Stop position of the hooking fitting, in which the lashing bar sometimes too is struck. 7 is the so-called stop position on the left shown, in which the lashing rod from the left corner fitting to the bottom right into one Zurrauge 38 runs on the ship deck 22. The left ear 39 undercuts in this position the eye 33 of the corner fitting 28 and thus forms an additional Securing against the corner fitting falling out 10.

Not shown is a so-called stop position on the right, in which the right ear 39 undercuts the eye 33 of the corner fitting 28. But this corresponds to shown stop position on the left analog.

4, the finger 15 is by a hump 40 from Main body 11 delimited. As a result, the hook fitting 10 is even better adapted the contour of the upper wall 35 of the eye 33 so that the Hook fitting 10 has an even better hold.

On the side opposite the finger 15 there is an additional 11 on the main body a hook 41 is arranged, the contour of which in the present case is the contour of a corresponds to conventional hooking fittings according to the prior art. On this results in an almost symmetrical material distribution of the hook fitting to a vertical plane through the center of the Eye 12 for the mounting bolt 13, so that symmetrical and thus cheaper forging forces arise in the manufacture of the hook fitting. On the other hand, the hook fitting can be used in combination with a midlock can also be used with a twistlock as usual. It is true possible to use the "finger side" in conjunction with a twistlock. By the hook is always (also) found the usual configuration.
