Tabular rack assembly

Claim 2

In combination with a stop-supporting structure comprising, an elongate wall having a row of stop-guiding slots extending therethrough, and an elongate means being parallel to said wall and affording at a distance from said wall a first elongate face facing away therefrom and affording between said wall and said first face a second elongate face facing toward said wall, a series of stops having generally C-shaped cutouts facilitating their association with the stop-supporting structure so that said elongate means is situated in said cutouts, said stops having stop ends extending through said guiding slots and having each a sharp point in its cutout by which it has pivotal anchorage contact with said first face, each stop having in its C-shaped cutout a face concentric to its pivotal anchorage contact with said first face, the relative locations of the faces on said elongate means being such as to strain the stops in the region of said cutouts to render the stops movable between set and unset positions against frictional resistance.

Claim 3

A stop-supporting rack assembly comprising, a stop-supporting structure having an elongate first wall and having an elongate second wall being transversely spaced from said first wall and extending parallel thereto, said first wall having a row of slots extending transversely therethrough in the direction in which said walls are spaced, a series of stops having each between said walls a main body portion which extends transversely of such walls and having each a stop tongue extending through one of said slots in said first wall to project outwardly therefrom, means including said second wall to associate the said stops individually for frictionally opposed pivotal setting movements about an axis location remote To said first wall and reacting against said second wall, said first wall being curved transversely of its length about an axis situated between said two walls, the slots in said first wall being of lengths to permit setting movements of said stops and the tongues about said axis location, each of said stops having an edge in contact with the curved wall beyond each of the opposite ends of the related slot, and a pivotal anchorage end on each stop facing toward said second wall out of contact with it, said means comprising a resiliently compressible member situated between said second wall and the anchorage ends of said stops to urge said stop edges thereon against said curved surface beyond the opposite ends of the slots, whereby said stops are frictionally held in the positions to which they are moved.

Claim 4

A stop-supporting rack assembly comprising, a stop-supporting structure having an elongate first wall and having an elongate second wall being transversely spaced from said first wall and extending parallel thereto, said first wall having a row of slots extending transversely therethrough in the direction in which said walls are spaced, a series of stops having each between said walls a main body portion which extends transversely of such walls and having each a stop tongue extending through one of said slots in said first wall to project outwardly therefrom, means including said second wall to associate the said stops individually for frictionally opposed pivotal setting movements about an axis location remote To said first wall and reacting against said second wall, said first wall being curved transversely of its length about an axis situated between said two walls, the slots in said first wall being of lengths to permit setting movements of said stops and the tongues about said axis location, each of said stops having an edge in contact with the curved wall beyond each of the opposite ends of the related slot, and a pivotal anchorage end on each stop facing toward said second wall out of contact with it, said means comprising a resiliently compressible member situated between said second wall and the anchorage ends of said stops to urge said stop edges thereon against said curved surface beyond the opposite ends of the slots, whereby said stops are frictionally held in the positions to which they are moved.
