Modular display means

Claim 2

A lightweight preformed environment resistant dimensionally stable rigid modular display block adapted for use with like blocks for exhibiting sundry products and adapted to be arranged for different display conditions, comprising the combination of: a homogeneous one-piece seamless polyhedral rigid hollow block body of plastic material having smooth, mar and soil resistant exterior surfaces, said body having side walls with top edges lying in a plane, a bottom wall, a top wall spaced below said plane and having peripheral portions uniformly spaced interiorly of said side walls, and recess walls and top edge walls of uniform narrow width joining said top wall and side walls adjacent the peripheral top edges of the side walls, said recess walls, top edge walls, and top portions of said side walls forming an inverted peripheral channel section of material for dimensionally rigidifying a top upstanding peripheral wall portion which extends continuously around the periphery of the block body and which defines a recess pocket of selected depth for containing objects to be displayed; said bottom wall having an exterior virtually planar surface; each of said side walls in cross section having a slightly concave configuration for stiffening said block body; and means including holes formed in peripheral top edge walls and means including corresponding projection on said bottom wall to releasably interlock one block body with at least a portion of another like block body.

Claim 3

A lightweight preformed environment resistant dimensionally stable rigid modular display block adapted for use with like blocks for exhibiting sundry products and adapted to be arranged for different display conditions, comprising the combination of: a homogeneous one-piece seamless polyhedral rigid hollow block body of plastic material having smooth, mar and soil resistant exterior surfaces, said body having side walls with top edges lying in a plane, a bottom wall, a top wall spaced below said plane and having peripheral portions uniformly spaced interiorly of said side walls, and recess walls and top edge walls of uniform narrow width joining said top wall and side walls adjacent the peripheral top edges of the side walls, said recess walls, top edge walls, and top portions of said side walls forming an inverted peripheral channel section of material for dimensionally rigidifying a top upstanding peripheral wall portion which extends continuously around the periphery of the block body and which defines a recess pocket of selected depth for containing objects to be displayed; said bottom wall having an exterior virtually planar surface; each of said side walls in cross section having a slightly concave configuration for stiffening said block body; and means including holes formed in peripheral top edge walls and means including corresponding projection on said bottom wall to releasably interlock one block body with at least a portion of another like block body; each side wall concave configuration including a rectangular center wall portion and trapezoidal wall portions extending from said rectangular portion in planes inclined to the plane of the rectangular portion.

Claim 4

A lightweight preformed environment resistant dimensionally stable rigid modular display block adapted for use with like blocks for exhibiting sundry products and adapted to be arranged for different display conditions, comprising the combination of: a homogeneous one-piece seamless polyhedral rigid hollow block body of plastic material having smooth, mar and soil resistant exterior surfaces, said body having side walls with top edges lying in a plane, a bottom wall, a top wall spaced below said plane and having peripheral portions uniformly spaced interiorly of said side walls, and recess walls and top edge walls of uniform narrow width joining said top wall and side walls adjacent the peripheral top edges of the side walls, said recess walls, top edge walls, and top portions of said side walls forming an inverted peripheral channel section of material for dimensionally rigidifying a top upstanding peripheral wall portion which extends continuously around the periphery of the block body and which defines a recess pocket of selected depth for containing objects to be displayed; said bottom wall having an exterior virtually planar surface; each of said side walls in cross section having a slightly concave configuration for stiffening said block body; and means including holes formed in peripheral top edge walls and means including corresponding projection on said bottom wall to releasably interlock one block body with at least a portion of another like block body; each side wall concave configuration including a rectangular center wall portion and trapezoidal wall portions extending from said rectangular portion in planes inclined to the plane of the rectangular portion.
