Abstract

The present invention relates to receptacles, in particular containers. Conventional receptacles (containers) have the disadvantage that workers are significantly exposed to safety accidents in docks and ships since locking the loaded containers together has been done manually. In addition, the task of the crane pilot is to accurately load the containers C1, C2, C3, C4 on the sides or top of each other. There is no adjustment device for this. It is an object of the present invention to provide a receptacle (container) which is mounted so that it can be locked horizontally with another similar receptacle (container) without manual work and at the same time can accurately position the container in the provided position. For this purpose, the present invention provides a receptacle comprising means such as a U-shaped guide rail 24 on its outer surface, which guide rail 24 is engaged with the same means of an adjacent receptacle and is positioned correctly in place. The receptacles C1, C2, C3, C4 are locked horizontally with respect to each other.

Description

Self-locking, self-adjusting receptacles, in particular, containers {SELF-LOCKING, SELF-ADJUSTING RECEPTACLES, PARTICULARLY CONTAINERS}

The present invention relates to a self-locking, self-adjusting receptacle, in particular a container. However, it is equally applicable to all receptacles in which a hollow body portion is provided on the outer wall to accommodate the locking device as a receptacle having a predetermined size and shape. Hereinafter, the present invention will be described in more detail by using a container as an example.

In recent years, cargo is transported around the world using primarily standardized containers. The container is lowered and loaded at the loading point, then loaded onto the vehicle (road or rail vehicle), and if necessary transported to the port or airport where the container is loaded on the ship or aircraft, and then fixed transport It is locked in another container and tied up with a rope, which is then carried back to the vehicle from the point of arrival to the destination and unloaded at the destination. Transport logistics require safe and fast loading and unloading of containers, and the equipment applied must be able to lift, transport and lock containers of different dimensions. The container has respective hollow bodies with elliptical openings on outward surfaces in the upper and lower corner regions. Locking devices, such as overheight frames or container spreaders, can be inserted into these elliptical openings, which have end regions (twist locks) with dimensions smaller than the elliptical openings of the hollow body portion. lock)]. At the same time that the torsion lock is inserted into the hollow body portion, the lock is mechanically twisted so that the container can be locked and transported in an overhaul frame or container spreader. When raised, the upper surface of the torsion lock bears against the lower portion of the upper wall of the hollow body portion.

In particular, the need for a shipload is particularly problematic when a number of containers loaded on each top and / or side must be locked together. In this case, the locking is carried out by manually locking with the container arranged on the top and / or side of each container by the engaging and locking member. This is dangerous and time-consuming because of the risk of injury when attaching the locking and locking members. For example, DE 100 42 458 and DE 101 04 067 are known to lock together a receptacle (container) which is loaded on top of each receptacle by an automatic locking system, in this way as a block. It is also possible to transport multiple receptacles (containers) locked together. As such, the problem of vertical locking is satisfactorily solved.

It is therefore an object of the present invention to provide a receptacle which can be locked horizontally in another receptacle of the same type without manual action and at the same time installed to occupy a fixed position for adjacent containers of the same type.

This object is achieved with the features of claim 1. As a result, it is possible to mechanically lock together the containers arranged on the top and sides of each container without the required manual work. At the same time, the container to be laid down is adjusted by the apparatus associated with subordinate claims 4 and 5 with respect to the container already laid down so that the container to be put down is positioned in a defined manner relative to the adjacent container.

Achieving the object according to claim 1 comprises attaching a means such as, for example, a guide rail to the outer side of the container, the means engaging the corresponding guide rail of an adjacent container, the container being lowered downwards from above. Because of this, they cause horizontal locking during the mutual engagement and progression of the respective guide rails. An essential advantage of the present invention is that conventional customary manual locking and lashing are unnecessary and therefore the risk of injury to workers in ports or ships is minimized. In addition, significant savings can be made in terms of manpower, time, and hence cost.

The means, ie the guide rail, for example, can be U-shaped, hooked or bent round. Any shape that can interlock with the means of an adjacent container can be considered.

The means, ie the guide rails, are inclined in such a way that they slope inward from the outside in the upper and / or lower regions, and the guide rails of each container play against each other so that they are self-adjusting relative to each other. Has As a result, the alignment of the containers becomes simpler for the crane operator, which no longer requires the operator to make an effort to position the other container correctly for each container at a distance from his crane workshop. This is because this is complemented by means on the side.

Hereinafter, although the present invention will be described with some exemplary embodiments, the subject matter of the present invention is not limited to these exemplary embodiments.

1 is a plan view of a number of containers locked together horizontally;

2 is a perspective view of the outer locking device,

3 shows an outer locking device having an inclined corner, viewed from the direction A of FIG. 2,

4 shows the outer locking device of two containers with inclined corners in the locking process.

1 shows in detail a plurality of containers C1, C2, C3, C4 having container corners 2 arranged on the back and sides of each other, the container corners 2 having an elliptical opening 211. A locking housing 21 called so-called corner casting is provided in the upper and lower regions of the corner 2. The containers are locked together by the outer locking device 24. This outer locking device 24 is U-shaped in this embodiment and the inner region is open so that the outer locking device 24 of the adjacent container can completely pass through the locking device. The transporting and setting-down procedure always takes place from top to bottom, and once one container is put in place, the next container is placed next to the first container from above. During this process, the locking device of the second container can be engaged with the locking device of the first container so that not only locking but also the second container can be guided and placed in position correctly. In the case where a plurality of containers are transported under each container and the plurality of containers are placed next to a plurality of containers already loaded, the outer locking device of the lowermost container to be transported is the outer locking device of the container already loaded on the top It may be inserted into and then passed through the outer loading device of the container loaded at the top for insertion into the outer loading device of the container loaded at the bottom and then the container loaded at the bottom. As a result, it is possible to save space and to accurately arrange containers. The outer locking device can be attached to the side of the container. Advantageously, the locking device can be attached to the container corner, as shown in FIG. 1.

2 shows a perspective view of the outer locking device 24 attached to the container corner 2 or integrally coupled to the container corner 2. The locking device 24 is located at the container corner 2 so that access to the elliptical opening of the corner casting is not impeded. Although not shown in FIG. 2, the same applies to corner casting of the bottom region of the container corner.

An outer locking device 24 having a corner inclined from outside to inside, shown from the gaze direction indicated by A in FIG. 2, can be seen in FIG. 3. The outer locking device consists of a long leg 241, a transverse leg 242 and a short leg 243. All three legs are inclined from outside to inside in the region of the leg upper end. The short legs 243 may be additionally inclined in part of the leg 243 'area to facilitate insertion of the outer locking device 24 "of another container.

Finally, Fig. 4 shows the outer locking device 24 from the perspective view according to Fig. 3, wherein the outer locking device 24 "of another container will be engaged with the locking device 24. From the perspective view, in the transverse direction Only the outer wall of the leg 242 "is visible. Thus, invisible legs 241 ", 243" are shown in dashed lines. It can be seen that the short leg 243 "has both the outwardly inclined inclined portion a and the outwardly inclined inclined portion b in its lower end region. This means that the short leg 243" is the outer locking device 24 ) And the inside of the outer locking device 24 is bounded by the interior of the legs 241, 242, 243. It can be seen that the width of the short leg 243 "is smaller than the width of the inner wall of the lateral leg 242. Thus, the short leg 243" has a play when sliding into the outer locking device 24. As shown in FIG. As a result of the fact that the upper regions of the legs 241, 242, 243 are inclined from the outside to the inside and the lower ends of the short legs 243 "are likewise inclined, the outer locking device (even in a rough transport business) There is sufficient freedom of movement for the 24 ") to slide into the outer locking device 24. Since the outer locking device is made of hardened steel, for example V2A steel, there is no fear that the outer locking device will be damaged when the container is transported and unloaded or aligned. This applies in particular when the devices are formed integrally with the container corner.
