BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to a locking device for the transport of containers, in particular, lift-on lift-off containers which, by means of a lifting device, for example, a lift-on lift-off mechanism, can be loaded onto the back of a transport vehicle.
2. The Prior Art
Appropriate bolting down devices for securing lift-on lift-off containers from sliding and tipping during transport on vehicles are known in the art. The bolting down devices encompass, for example, horizontal pins arrayed on the underside of the container which slide into eyes arranged on the vehicle as soon as the container has assumed its intended final position, the in-transit position, on the vehicle. Actuable bolting down elements are also known in the art which consists of pivotable, hook-like flaps aligned in a longitudinal direction of the vehicle about horizontal axes which can overlap the flanges of reinforcement sections, ground guides or similar projections located on the underside of the container thereby securing the container against its lifting up from the loading surface.
Combinations of the device described hereinbefore are also possible in providing a locking device for the transport of a lift-on lift-off container.
Existing systems for securing lift-on lift-off containers during transit have the disadvantage that they are specially adapted for use in connection a lift-on lift-off mechanism already known in the art. In practical operation it may of course turn out that lift-on lift-off containers are not loaded onto or off of transport vehicles by means of a lift-on lift-off mechanism but, rather, by means of another lifting device, for example, an ordinary crane. One could imagine this is the case with railroad cars, truck trailers, watercraft and the like in which instances so-called loading cranes are especially used with which vehicles are frequently equipped in order to facilitate the on- and off-loading of parcel freight.
The locking devices for the transport of containers known in the art actually prevent movement of the containers in a direction perpendicular to the loading surface on which the containers are intended to be positioned or loaded, with the result that a lift-on lift-off container which has been on-loaded with a lift-on lift-off mechanism, for example, cannot be off-loaded by means of another lifting device, a crane.
SUMMARY OF THE INVENTION
The task of the invention is to devise a locking device for the transport of containers in such a way that it can perform its function both during transloading of the containers using the lift-on lift-off mechanisms known in the art as well as with other lifting devices like, for example, an ordinary crane.
This task is resolved by the invention in that adjusting elements are arranged on the underside of the container in the level of its loading surface, in that arresting elements are arranged on the loading surface, and in that on each arresting element an adjusting element associated with it is maintained in the in-transit position of the container.
The adjusting elements determine the position to be assumed by the container on the loading surface of a vehicle. Adjusting elements and arresting elements may, therefore, be structurally configured as simple stops which come to lie one on top of the other as soon as the container has assumed its final in-transit position on the loading surface. It does not matter whether the container has reached this position through the action of a lift-on lift-off mechanism or through the action of another lifting device, for example, an ordinary crane. The appropriate configuration of the adjusting element and the arresting element ensures that each adjusting element on the arresting element is maintained in the intended in-transit position of the container, whereby the desired securing of the container during transit has been assured.
This can, for example, be achieved by configuring the adjusting element and arresting element as reciprocally intermeshable form-fitting ele
