Claim:
A shelf arrangement for attachment to an upright wall, comprising: a monolithic one-piece shelf unit constructed of an extrudable material; said shelf unit being horizontally elongated and having an L-shaped cross section defined by a horizontal leg part which adjacent a rear edge is monolithically joined to a lower edge of an upright leg part which is cantilevered upwardly in generally transverse relation to the lower leg part, said lower leg part defining thereon a generally horizontally planar upper surface which functions as a support surface for removable objects, said lower and upright leg parts extending horizontally throughout the lengthwise extent of the shelf unit; said lower leg part having a nose part which extends lengthwise along a horizontally extending free edge thereof, said nose part defining therein a channel-like groove extending lengthwise therealong throughout the length of said lower leg part; a horizontally elongate metal reinforcing beam positioned within and extending lengthwise throughout substantially the lengthwise extent of said groove and maintained in engagement with said nose part for reinforcing the nose part of said lower leg part against vertical bending due to external loading of said upper surface; said lower leg part having at least one main groove formed therein and opens downwardly through an undersurface thereof, said main groove extending horizontally lengthwise throughout the lengthwise extent of the lower leg part in generally parallel but rearwardly spaced relation from the lengthwise extending free edge, said main groove in cross section having an undercut configuration to permit a removable bracket structure associated with a detachable accessory to be suportingly engaged therein; and a mounting bracket attached to said shelf unit and projecting rearwardly thereof for supportive engagement with an upright wall.
