Patent ID: 7823520

Claim:
A portable work surface for attachment to a stationary structure, the stationary structure having a stationary work surface, comprising: a platform having a planar work surface, and a lower surface opposite the planar work surface; a hinge comprising a hinge member rotatably attached to the lower surface of the platform; the hinge comprising first and second arms extending at an angle substantially orthogonal to the hinge member; a first support member rotatably attached to said first arm, and a second support member rotatably attached to said second arm; wherein said first and second support members are configured to support the platform at an elevation above the stationary work surface; a first vertical support coupled to said first support member, and a second vertical support coupled to said second support member; wherein said first and second vertical supports are configured to abut at least partially against a side edge of the stationary structure; a first bracing member coupled to the first vertical support, and a second bracing member coupled to the second vertical support; wherein the said first and second bracing members are each configured to contact the stationary work surface; and a first clamping member coupled to the first vertical support, and a second clamping member coupled to the second vertical support; wherein said first and second clamping members are each configured to contact a lower surface of the stationary structure to releasably secure the first and second vertical supports to the stationary structure; wherein the first and second support members are configured to rotate about the first and second arms of the hinge such that the first and second support members and first and second vertical supports collapse into a stowed orientation horizontally against the lower surface of the platform.
