A shelf support apparatus includes a pair of spaced apart longitudinally extending channel members facing each other and crosspieces which extend between the channel members and supports the shelf. Each channel member defines a guideway therein. The side of each channel member which faces the other channel member has two spaced apart front walls defining a slot between them. The slot extends along the length of the channel member. A plurality of support means are formed on each front wall of each channel member and extends into the guideway of the channel member. The support means are preferably longitudinally spaced along the channel members. Each crosspiece has relatively narrow portions extending through the slots in a pair of channel members and relatively wide support portions disposed within the guideways in the pair of channel members. Each end portion of the crosspiece is supported on support means extending into the guideways in the pair of channel members. The crosspieces, and therefore the shelf, can be readily repositioned along the channel members without removing the crosspieces from the guideways in the channel members.

Apparatus for use in supporting a shelf or the like, comprising a pair of spaced apart longitudinally extending channel members having respective longitudinally extending slots disposed in facing relation with each other, a crosspiece extending between said pair of channel members, said crosspiece having integral end portions which extend through the facing slots and into said channel members, and a plurality of support means longitudinally spaced within each of said channel members for engaging and supporting the end portions of said crosspiece within the channel member to support the end portions of the crosspiece when the crosspiece is in a first orientation relative to the channel members, the crosspiece being turnable to a second orientation relative to the pair of channel members while its end portions are disposed within said pair of channel members, the end portions of the crosspiece being released from engagement with the support means in the pair of channel members when the crosspiece is in said second orientation, the end portions of the crosspiece being longitudinally movable in the pair of channel members while the crosspiece is in its second orientation to change the position of the crosspiece relative to the pair of channel members, each of said pair of channel members defining a longitudinally extending guideway, the support means in each channel member projecting into the guideway for engaging and supporting an end portion of a crosspiece disposed therein when the crosspiece is in said first orientation, the end portions of a crosspiece which extends within a guideway in a channel being dimensioned to (i) slide in both longitudinal directions in the guideway when the crosspice is in its second orientation, (ii) turn in the guideway as the crosspiece turns between its first and second orientations, and (iii) rest on a support means in the guideway when the crosspiece is in its first orientation, each of the facing slots in the channel member having a predetermined width, and the guideway in each channel member having a predetermined width which is greater than the width of the slot in the respective channel member, each of the end portions of the crosspiece including a relatively narrow neck portion which has a width which is less than the predetermined width of the slots in the channel members and a relatively wide support portion which has a width which is greater than the predetermined width of the slots in the channel members, and the support means in each channel member projecting into the guideway in the channel member at a location outside the width of the slot associated with that channel, the end portions of the crosspiece and the guideways in the channel members being dimensioned to allow relatively unobstructed longitudinal movement of an end portion of a crosspiece in the guideway in a channel member when the crosspiece is in its second orientation, each channel member including first and second coplanar front walls which are spaced apart from each other and define the longitudinal slot in the channel member, and each support means in the channel member comprising at least one support member projecting into the guideway in the channel member from at least one of said first and second front walls in the channel member.
