Embodiment Construction

[0031] The figures are merely schematic representations of preferred embodiments of the locking device according to the invention and are given as non-limiting exemplary embodiments.

[0032] In the drawings, the same or corresponding parts are designated by the same reference numerals. see figure 1 with 2 , the locking device 1 is depicted here as an ISO standardized corner fitting 2 for locking a freight container.

[0033] The locking device 1 comprises a locking mechanism 3 which can be figure 1 open position shown in and figure 2 Adjust between the closed positions shown in . In the open position, the locking mechanism can pass freely through the opening 4 of the corner fitting 2 . In the closed position, the locking mechanism 3 hooks behind the wall of the corner fitting 2 surrounding the opening 4 .

[0034] The locking device 1 comprises a biasing mechanism 6 which biases the locking mechanism 3 into the open position. The locking device 1 further comprises an ...

Abstract

A locking device for locking an ISO-standardized corner fitting of a freight container, comprising: locking means which are adjustable between an opened position in which the locking means can freely pass an opening of the corner fitting and a closed position in which the locking means hook behind the opening of a wall surrounding the corner fitting; operating means which, upon placement of a container on the locking device, are adjustable through cooperation with a wall of the corner fitting from an unloaded initial position to an end position loaded by the weight of the container, and an adjusting mechanism which couples the locking means and the operating means in a manner such that the initial position of the operating means corresponds to the opened position of the locking means and that the end position of the operating means corresponds to the closed position of the locking means, and that upon placement of a corner fitting of a container on the locking device, the weight load of the container energizes the locking means towards the closed position.

Description

technical field [0001] The invention relates to a locking device for locking ISO standardized corner fittings of freight containers. Background technique [0002] In fact, the most common locking device known to those skilled in the art is named "twist lock" and forms a simple and reliable locking mechanism for securing a freight container fitted with ISO standardized corner fittings to a vehicle such as a container chassis . [0003] The disadvantage of the "twist lock" is that the lock must be adjusted by hand, which is a relatively difficult and time-consuming task. Especially when the vehicle is just loaded, the time-consuming fastening process impairs efficiency. For example, the container chassis has just been loaded with a container crane, and the fastening process will make the loading site occupied for too long. [0004] In practice, for vehicles where containers are picked up and transported very frequently, such as stacker cranes and straddle carriers, the lock...
