Abstract:
A work surface defining device, comprising:(a) a pair of rigid support members attachable to a support structure; (b) a platform defining a work surface surrounded by spaced apart opposite front and rear edge portions and spaced apart opposite side edge portions extending between said front and rear edge portions, said platform being movable between first and second positions relative to said rigid support members; and (c) a pair of quick release locking mechanisms each for releasably attaching said platform at a respective one of said opposite side edge portions thereof upon a corresponding respective one of said rigid support members when said platform has been moved from said first position to said second position relative to said rigid support members, each of said quick release locking mechanisms including (i) a catch provided on said respective one of said rigid support members, and (ii) a locking latch mounted on said respective one of said opposite side edge portions of said platform and pivotally movable about a pivotal mounting axis, defined by said quick release locking mechanism, relative to said platform between a first over-centered position relative to said pivotal mounting axis in which said locking latch is in a released relationship with said catch on said respective one of said rigid support members to thereby permit subsequent movement of said platform from said second position to said first position relative to said support member and a second over-centered position relative to said pivotal mounting axis, being opposite said first over-centered position, in which said locking latch is in a latched relationship with said catch on said respective one of said rigid support members to thereby block subsequent movement of said platform from said second position to said first position relative to said support member.
