A display rack and display rack shelf. The display rack includes a frame which supports one or more of the shelves. The frame has first, second and lateral sides and defines a plurality of vertically-spaced pairs of horizontally-aligned apertures. The shelf includes first and second end portions. The first end portion includes a movable support element with a single piece cross member and a pair of movable engagers at opposite lateral sides of the shelf for engagement with a selected pair of apertures along the first or second sides of the frame. The single-piece cross member and each movable engager of the movable support element is slidable toward and, alternatively, away from the second end and is rotatable about a corresponding axis to permit setting of the angular position of the shelf. The second end portion side is configured for pivotal engagement with one of the front and rear sides of the frame. The shelf of the rack is adjustable for a plurality of angular orientations by a selective positioning of the first end portion with respect to the second end portion.

1. A display rack, comprising: a frame having first and second pairs of upright elements, the upright elements defining a shelf space and a lateral dimension therebetween and including a plurality of vertically-spaced apertures, the apertures of such upright elements including pairs of apertures at corresponding vertical positions therealong; andat least one shelf of a principal width at least partially within the shelf space, the shelf including (a) first and second ends, (b) a first end portion with a pair of movable engagers for engagement with a pair of apertures of one of the first and second pairs of the upright elements, and (c) a second end portion with a pair of nonmovable engagers for engagement with a pair of the apertures of the other of the first and second pairs of the upright elements, the pair of movable engagers being the ends of a single-piece cross-member defining a single axis, the single-piece cross-member being rotatable about the single axis and slidable toward and, alternatively, away from the second end, thereby allowing angular adjustment of a shelf plane by selective positioning of the first end portion with respect to the second end portion wherein the vertically-spaced apertures for supporting the pair of movable engagers face the vertically-spaced apertures for supporting the pair of nonmovable engagers. 2. The rack of claim 1 wherein the frame has first and second sides and the pair of apertures engaged with the movable engagers face the second side of the frame and the pair of apertures engaged with the nonmovable engagers face the first side of the frame. 3. The rack of claim 1 wherein each aperture is substantially round. 4. The rack of claim 1 wherein the shelf has two lateral edge members defining the principal width for the entire shelf, the principal width being less than the lateral dimension of the frame. 5. The rack of claim 4 wherein both the nonmovable engagers and the movable engagers extend beyond the principal width of the shelf. 6. The rack of claim 1 wherein each of the movable engagers rotate in separate substantially-parallel planes substantially orthogonal to the shelf plane. 7. The rack of claim 6 wherein the pair of movable engagers rotates simultaneously when the single-piece cross-member rotates. 8. The rack of claim 1 wherein: the shelf has a plurality of lateral cross elements; andthe single-piece cross-member is slidable within an adjustment region bounded by a first lateral cross member proximate the first end and a second lateral cross member between the first lateral cross member and the second end. 9. The rack of claim 8 wherein the adjustment region is about a quarter of the dimension between first and second ends of the shelf. 10. The rack of claim 9 wherein the angular adjustment of the shelf plane is allowed between about 0° and about 60° with respect to horizontal. 11. The rack of claim 1 wherein the single-piece cross-member includes an intermediate portion disposed below the shelf plane and extending therealong to support the shelf with respect to the frame, the intermediate portion defining the single axis. 12. The rack of claim 11 wherein each of the movable engagers includes a catch outward from the principal width rotatable about the single axis in a plane substantially orthogonal with respect to the shelf plane for engagement with a selected one of the apertures. 13. The rack of claim 12 wherein the catch rotation is limited to about 70°. 14. The rack of claim 1 wherein the angular adjustment of the shelf plane is allowed between about 0° and about 60° with respect to horizontal. 15. The rack of claim 1 wherein each upright element is a hollow tube. 16. The rack of claim 15 wherein each catch rests against an edge of the hollow tube defining the aperture. 17. The rack of claim 15 wherein each upright element is formed by at least two interconnected sections which are separable to minimize dimensions of the rack when disassembled. 18. The rack of claim 1 wherein each of the nonmovable engagers projects beyond the principal width and terminates in a catch for engagement with a selected one of the apertures.
