Hinge with lifting-out protection

Claim 1

A hinge for lifting-out protection of a turnable and releasable side wall of a commerical vehicle on its chassis, comprising a first hinge part mountable on said side wall and provided with a first pivot pin having a substantially horizontal longitudinal axis and extending in a first axial direction, a second pivot pin having a substantially horizontal longitudinal axis and extending in a substantially opposite second axial direction, said pivot pins having free ends spaced from one another by a first distance, and a collar extending radially beyond and over a part of the periphery of said first pivot pin, said longitudinal axes of said pivot pins being arranged in alignment with one another, said pivot pins having a connecting region, a web being formed onto said connecting region, a base plate provided on said first hinge part and connected with said pivot pins via said web; and a second hinge part mountable on said chassis and having a recess, a substantially horizontal opening, and a substantially horizontally extending shell which is open upwardly and is spaced from said opening by a second distance, said second distance being smaller than said first distance, said hinge parts being formed so that in an upwardly turned position of the side wall and over a downward angular turning region of the side wall said first hinge part is located in a first axial end position in which said first pivot pin of said first hinge part extends into said opening of said second hinge part and said second pin free end is axially spaced from said shell so that said first hinge part and therefore the side wall cannot be lifted out, in said first axial end position said collar of said first hinge part is located in said recess of said second hinge part with a limiting surface on the collar in abutment with a limiting surface in the recess so that said first hinge part and therefore the side wall cannot move axially in said second axial direction, whereas, when the side wall is turned down beyond said angular turning region, said collar of said first hinge part disengages from said recess of said second hinge part and said first hinge part can be moved to a second axial end position in which said first pivot pin of said first hinge part is completely withdrawn from said opening of said second hinge part and said second pivot pin of said first hinge part is supported from below in said upwardly open shell of said second hinge part and an abutment surface on the web which faces toward said shell being in abutment with an abutment surface on the side of the shell so that the side wall is prevented from falling down and at the same time said first hinge part can be removed from said second hinge part upwardly thereby lifting the side wall out.
