Abstract

For facilitating the picking up and setting down of a container in a containerised goods transport system, there is provided at each corner of the container a lifting arrangement comprising a retractable leg housed with an operating ram in a post which is mounted by hinges on a corner frame member to swing about a vertical axis between a position laterally outboard of the container to allow the leg to be extended, and a stowed position in which the post with leg retracted is housed in a recess in a corner frame member so occupying otherwise non-used space.

Claims

1. A goods container for use in containerised goods transport systems, comprising a container body which is provided at each vertical corner with a retractable leg structure, said structure comprising a fixed pillar having a vertically-extending recess which is open laterally of the container, a tubular post hinged to said pillar to swing about a vertical axis between a stowed position within the recess and an operative position extending laterally outboard of the container, a hollow ground-engaging leg slidably engaged in the tubular post to move vertically, each of said post and leg being of corresponding rectangular cross-sections, a ram accommodated within and connected between the post and the leg to effect sliding of the leg, and locking means for retaining the post in its stowed and operative positions, the locking means including a part which is mounted on the pillar to move into and out from the recess and which engages the post in its operative position to prevent the post moving to its stowed position and which is retained in the recess by the post when the latter is stowed.

2. A goods container as claimed in claim 1 wherein said part includes a plate which swings downwardly about a horizontal axis from a position within the recess to a position in which it is operative to prevent swinging of the post from the laterally-outboard position.

3. A goods container according to claim 2, wherein the locking devices include retainers for securing the post and plate together in the laterally-outboard position and for securing the post to the pillar structure in the stowed position.

4. A goods container according to claim 2, wherein the plate, when swung down, lies in the path of the post to prevent it from swinging from the laterally-outboard position.

5. A goods container according to claim 2, wherein the plate, when swung down, acts as a strut holding the post in the laterally-outboard position.

6. A goods container according to claim 1, wherein the post has hinge plates connecting it to the pillar structure and a hinge plate is arranged to hold the retractable part within the recess.

7. A goods container according to claim 1, wherein the locking devices comprise a strut-forming bar pivoted to the pillar structure, and a retainer by which a free end of the bar is secured to the post in its laterally outboard position.

8. A goods container according to claim 1, wherein the locking devices include a bar hinged by one end to the post and slidable in the pillar structure as the post is swung between its stowed and laterally-outboard positions, and a retainer to secure the bar to the pillar structure in each of said positions.
