Folding lateral extension adjoining at least one loading surface of a cargo-carrying vehicle

摘要

A lateral extension (1), for road and rail vehicles, comprising a multitude of individual shafts (5) assembled so as to pivot freely, at each of their extremities, firstly, with regard to the interior extremity secured to the vehicle, on a longitudinal structure (11) that is fixed in relation to the load-carrying platform and, secondly, as regards the exterior extremity, on an edge and connecting rigid longitudinal member (10). The shafts bear, over a portion of their length, on an adjacent flat support surface (13) that is fixed in relation to the load-carrying platform, and are cantilevered towards the exterior over the remainder of their length. The extension can be moved to a deployed position, so that the supporting surface (14) provides a passageway, and, a retracted position of lesser width, and incorporates a railing. A changeover from one position to the other is accomplished by pivoting in a horizontal plane.

主权项

1. A load-carrying lateral extension designed to be assembled along a length a longitudinal side of at least one load-carrying platform carrying the load of a load transport vehicle, to act as a supporting surface for bearing loads or for circulation of an operator, wherein the load-carrying lateral extension comprises:
a side beam (12) integral with or fixed along the longitudinal side of the at least one load-carrying platform; a rigid longitudinal junction component (10) forming an exterior limit of the load-carrying lateral extension; a multitude of individual preferably rectilinear supporting components (5) being retractable by pivoting around respective vertical axes towards each other, and connecting the side beam (12) to the rigid longitudinal junction component; each of the rectilinear supporting components is:
articulated pivotally at a first extremity thereof so as to pivot on the side beam (12) around the vertical axis, the vertical axis being located on an inward side of the side beam;supported at the first extremity over a fraction of a length thereof by a load-carrying surface of the side beam;articulated pivotally at a second extremity thereof on the rigid longitudinal junction component (10); andat the second extremity thereof, each of the rectilinear supporting components engages the rigid longitudinal junction component (10), and is cantilevered laterally in relation to the at least one load-carrying platform, so as to form the supporting surface acting as a means of support and a route for passage and circulation of the operator.
