Abstract
Abstract An assembly set for erecting roller conveyors includes a plurality of structural elements each of which has a housing provided in its upper side with a recess in which a spherical or cylindrical rolling element is turnably accommodated with a portion thereof projecting upwardly beyond the upper side so as to contact and support a load which is to be transported. Releasable connecting means, separate from or provided on the respective structural elements, serves for releasably connecting the same to one another so as to enable the construction of differently configurated roller conveyors at the will of a user.
