Abstract
Abstract Adjustable display shelf apparatus including vertical support elements defining at least one external groove opening into an enlarged lengthwise undercut slot for receiving a mating portion of a projecting shelf support bracket. The projecting shelf support bracket may be formed with slots along one edge that define an edge configuration conforming to the configuration of the undercut slot thereby allowing the shelf support bracket to be adjustably supported within the undercut slot. The shelf support brackets may be infinitely adjustable relative to the vertical support elements and may be secured in any desired position relative to the support elements by friction inducing shelf bracket restraint elements.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
228 words
A display unit comprising: vertical support means having opposed spaced shoulder means defining an elongated groove therebetween and having elongated chamber means formed therein and being disposed behind said opposed shoulder means, said vertical support means defining first generally planar friction surface means; support bracket means having a support portion for supporting objects thereon, said support bracket means having a face portion of a configuration generally corresponding to the cross-sectional configuration of said elongated groove and said elongated chamber, said face portion of said bracket means being disposed within said elongated chamber means and extending through said elongated groove and being movable along said groove and chamber, said face portion defining second generally planar friction surface means, said support bracket means having a transverse latch aperture formed therein, at least a portion of said aperture intersecting the plane of said first friction surface means; and latch pin means being disposed within said transverse aperture of said bracket means and having cam surface means defined thereon, said latch pin means being movable relative to said bracket means between a locked position where said cam surface means engages said vertical support means and urges said first and second friction surface means into friction locked engagement and a released position where said cam surface means is retracted to a position releasing said frictional engagement between said first and second friction surfaces.
Claim 2
Dependent Claim
228 words
A display unit comprising: vertical support means having opposed spaced shoulder means defining an elongated groove therebetween and having elongated chamber means formed therein and being disposed behind said opposed shoulder means, said vertical support means defining first generally planar friction surface means; support bracket means having a support portion for supporting objects thereon, said support bracket means having a face portion of a configuration generally corresponding to the cross-sectional configuration of said elongated groove and said elongated chamber, said face portion of said bracket means being disposed within said elongated chamber means and extending through said elongated groove and being movable along said groove and chamber, said face portion defining second generally planar friction surface means, said support bracket means having a transverse latch aperture formed therein, at least a portion of said aperture intersecting the plane of said first friction surface means; and latch pin means being disposed within said transverse aperture of said bracket means and having cam surface means defined thereon, said latch pin means being movable relative to said bracket means between a locked position where said cam surface means engages said vertical support means and urges said first and second friction surface means into friction locked engagement and a released position where said cam surface means is retracted to a position releasing said frictional engagement between said first and second friction surfaces.
Claim 3
Dependent Claim
66 words
A display unit as recited in claim 1, wherein: said support bracket means has a latch aperture formed therein; and said latch means comprises an elongated pin element having a generally planar cam surface formed thereon and being disposed in angular relation to the longitudinal axis of said pin, said cam surface being disposed in engagement with said first friction surface of said vertical support means.
Claim 4
Dependent Claim
86 words
A display unit as recited in claim 1, wherein: said latch aperture being formed in substantially normal relation to said support bracket means; and said latch means comprises an elongated friction latching pin being rotatably received within said latch aperture, said elongated pin having rotary cam surface means formed thereon and being disposed in eccentric relation to said pin, said cam surface means, upon rotation of said pin being movable into or away from camming engagement with said first friction surface of said verticle support means.
Claim 5
Dependent Claim
32 words
A display unit as recited in claim 3, wherein: said cam surface means comprises circular elements disposed at each extremity of said pin in eccentric relation to the axis of said pin.
Claim 6
Dependent Claim
32 words
A display unit as recited in claim 4, wherein: one of said circular elements having drive means formed thereon and being engaged by a drive element to achieve rotation of said pin.
Claim 7
Dependent Claim
52 words
A display unit as recited in claim 1, wherein: said face portion of said bracket means has opposed elongated guide grooves formed therein defining third friction surface means, said opposed grooves receiving said opposed shoulders of said verticle support element and said third friction surface means engaging said second friction surface means.
Claim 8
Dependent Claim
36 words
A display unit as recited in claim 1, wherein: said support element has a plurality of grooves and chambers extending along the length thereof and receiving a plurality of said bracket means in locking relation therewith.
Claim 9
Dependent Claim
48 words
A display unit as recited in claim 1, wherein: saId support member includes a back wall and facing side walls defining said chamber and said bracket supports the facing portion thereof within said chamber short of contact with said back wall and said side walls of said chamber.
