A work surface is mounted on a pair of brackets which are releasably mounted on and project outwardly in cantilevered relationship from a panel adjacent the opposite ends thereof. The work surface, in each end rail thereof, mounts a manually-actuated latching lever which is biased down into latching engagement with the respective bracket. The latching lever prevents the work surface from moving away from the panel and from being lifted upwardly adjacent its rear edge. The latching lever has the end thereof accessible from beneath the rear edge of the work surface so as to be manually moved upwardly to release the work surface from the bracket, whereupon the work surface can be slidably displaced outwardly away from the panel through a limited extent. When the work surface is manually slidably moved forwardly toward the panel, the latching lever automatically re-engages its respective bracket.

In combination, an upright wall structure defining a pair of horizontally spaced urpights each having a wall with a vertically extending row of elongated slots therein, a bracket structure adapted for releasable securement to each said upright, said bracket structure including forward1y and downwardly projecting hook means positioned for engagement with the slotted wall of the respective upright, and a shelflike structure positioned on and releasably attached to said bracket structures in a normal use position whereby the shelflike structure has a front edge positioned closely adjacent said wall, said shelflike structure projecting substantially horizontally outwardly from said wall in cantilevered relationship thereto, the shelflike structure also having a rear edge which extends substantially parallel to said front edge and remotely located from said wall, the improvement comprising manually releasable latch means coating between shelflike structure and said bracket sturctures for (1) maintaining said shelflike structure in said use position when latched and (2) permitting said shelflike structure to be horizontally slidably moved relative to said bracket sturctures rearwardly away from said wall through a selected extent into a service position when unlatched, said latching means including a manually releasable latching member movably supported on one of said shelflike and bracket structures and being normally biased toward a condition of latching engagement with the other of said shelflike and bracket structures, said latching member having a part thereof which is manually accessible from a location disposed in the vicinity of said rear edge, said latching member comprising a horizontally elongated latching lever pivotally mounted on said shelflike structure adjacent each end edge thereof and disposed for latching engagement with the respectively adjacent bracket structure, said latching lever being hingedly mounted adjacent its forward end on said shelflike structure, said latching lever having adjacent its rearward end a finger-engaging part which is disposed in the vicinity of the rear edge of said shelflike structure so as to be manually releasable, said shelflike structure inlcuding an end rail extending along each and edge thereof between said front and rear edges, said end rail having a substantially hollow channel-like cross section, said latching lever being positioned within and extending along each said end rail, a sleevelike guide grommet fixed within said end rail adjacent the rear edge of said shelflike structure, said sleevelike guide grommet being aligned with an access opening formed in the underside of said end rail, said grommet having a vertical guide slot formed therein, said latching lever adjacent the rear free end thereof having a part thereof vertically slidably guided within said guide slot, said finger-engaging part of said latching lever being positioned within said sleevelike guide grommet, said latching lever having a downwardly projecting latching part protruding downwardly therefrom, slots means formed in and opening downwardly of said bracket structure of receiving therein said latching part when said shelflike structure is in said use position, spring means normally biasing said latching lever in a direction causing said latching part to project into said slot means, and means for slidably guiding the movement of said shelflike structure on said bracket structures as the shelflike sturcture moves between said use and service positions.
