摘要 |
A four-bar linkage joint device (10) for pivotably connecting two structures comprises an additional rod for keeping aligned the two main rods (13,14) of said four-bar linkage in order to prevent fortuitous movements of the joint when it is in its open configuration. Release means favourably arranged allows misaligning the rods for closing the joint device. A table, in particular for campers or camping provides foldable legs which can be closed under the table top thanks to joint devices according to the invention which pivotably connect the legs to the top.
