Abstract: A knockdown fitting for connecting panels in right angular relation. The knockdown fitting includes a pair of bracket members of the same configuration and each having a mounting pad portion and a blade portion extending perpendicular to the inner side of the mounting pad portion and medially between relatively parallel side edges of the mounting pad portion, the blade portions of the bracket members having a notch in their lead end edges adapted to interfit when the blade portions are in relatively crossing right angular relationship.

Abstract: A knockdown structure including at least two panels adapted to extend transverse to each other, an intermediate bar segment attached to a side face of one of the panels and two end bar segments attached to side face of the other of the panels and disposed at opposite ends of the intermediate bar segment. The intermediate and end bar segments have end faces in abutting relation when the bar segments are in alignment and the abutting end face on the intermediate and end bar segments define supplementary angles extending oblique to both of the panels at angles such that the intermediate bar segment forms a wedge type interlock with the end bar segments.

Abstract: An interlocking shelf and shelf bracket construction in which the shelf brackets have an upper shelf supporting surface and forwardly and rearwardly facing abutment faces extending transverse to the shelf supporting surface, and the shelf has forward and rear abutment strips arranged to engage the forward and rear abutment faces on the shelf brackets. The rear abutment strip is mounted on the shelf to have portions resiliently movable relative to the shelf in a direction away from the forward abutment strip to resiliently clamp first and second abutment faces on the shelf brackets between the first and second abutment strips.

Abstract: A shelf bracket including a shelf bracket member formed of non-metallic material and having an upper shelf supporting surface and a rear abutment surface and a generally L-shaped metal shelf attaching bracket for mounting the shelf bracket member on a supporting surface. The L-shaped shelf attaching bracket has a generally horizontal upper leg and a depending tongue at its forward end extending downwardly into a notch in the shelf bracket member and a generally vertical rear leg with a tongue at its lower end extending forwardly into a notch in the rear portion of the shelf bracket member. Protrusions are formed on the tongues to engage one wall of the notch and press the tongues into firm engagement with the other wall of the notch to inhibit bending of the tongues relative to the respective leg and to also hold the shelf attaching bracket in assembled relation on the shelf bracket member.

Abstract: A shelf apparatus including upper and lower shelves and upright shelf supports attached to the shelves and extending therebetween to support the shelves in fixed vertically spaced relation, and a removable door assembly including an upright door mounting member movably positioned between the upper and lower shelves alongside one of the shelf supports and having upper and lower shelf engaging abutments, at least one of which is manually adjustable to forcibly increase the spacing between the upper and lower shelf engaging abutments to jam the door mounting member vertically between the upper and lower shelves, and a door mounted on the door mounting member for movement relative thereto. The door can be hingedly mounted on the door mounting member for swinging movement relative thereto on an upright axis.

Abstract: A shelf bracket including a bracket member formed of non-metallic material and having an upper shelf supporting surface and a rear abutment surface and a generally L-shaped metal attaching member for mounting the shelf bracket member on a supporting surface. The non-metallic bracket member has recesses at the upper rear corner thereof for receiving the metal attaching member and the bracket member has a downwardly extending notch in its upper surface for receiving a downwardly extending tongue on the metal attaching member to horizontally anchor the bracket member adjacent its upper surface. A second anchor extends horizontally from the lower portion of the attaching member into the bracket member to vertically support the bracket member.

Abstract: A free standing shelving system including a plurality of shelves and a plurality of spindles for supporting the shelves, some of the shelves being arranged in endwise adjacent relation whereby the shelving system has some abutting shelf ends and some free shelf ends. The shelves each have like corner openings in all four corners with one spindle at each corner opening at the free end of the shelves and one spindle at the contiguous corner openings in endwise abutting shelves. The spindles are disposed in endwise aligned relation with their axes at the virtual corners of the shelves and the spindles have end faces on their adjacent ends that overlap the shelves adjacent the corner openings.

Abstract: A knock-down shelving apparatus including a plurality of vertically spaced shelves and a plurality of uprights extending between each shelf and the next lower shelf. Each upright has a multi-sided core and panels adhesively secured to the outer side faces of the core with one end of the core spaced axially outwardly from one end of the panels to provide a multi-sided tongue at one end of the uprights adapted to extend through a similarly shaped opening in the shelf and with the other end of the core spaced axially inwardly of the other ends of the panels to provide a socket for relieving the tongue on an axially aligned upright after it has passed through an opening in the shelf. The shelves have depending flanges engageable with the uprights to enhance the stability of the shelving apparatus when assembled.
