A device for connecting the adjacent ends of two sections of a longitudinal member of a demountable framework for supporting the tarpaulin of the body of a goods vehicle

摘要

In a device for connecting the ends of two sections (18, 20) of a longitudinal member of a demountable framework for supporting the tarpaulin of the body of a goods vehicle, in which the two sections are supported by removable intermediate uprights and the remote ends of the two sections are supported by end uprights of the framework, the adjacent ends of the two sections (18, 20) of the longitudinal member are provided with lower mutual engagement means (38) such as to define a hinge with a horizontal axis between the two sections (18, 20) and are provided with upper adjustable separating means (42, 48) which enable the longitudinal member to be prestressed with an upward flexion centred on the hinge so as to compensate for the downward flexion caused by the weight bearing on the longitudinal member when the latter is supported solely by the end uprights.
