Abstract:
A detachable shelf assembly comprising:(a) a platform having(i) an upper panel and a lower panel attached at ends thereof to form an approximately 90.degree. corner, said upper panel having an outer surface and said lower panel having an outer surface, and(ii) a coaxial pair of trunnions extending from said upper panel substantially parallel to and a distance from said corner, said trunnions having a radius;(b) a pair of brackets, each of said brackets having a top surface, a retaining wall, and a groove, said groove of each bracket being a mirror image of the other;(i) each of said grooves having a front wall and a back wall, each extending downwardly from said top surface, and an opening disposed therebetween, said opening having a width slightly larger than twice said trunnion radius;(ii) said back wall extending vertically downwardly and terminating at a trough;(iii) said front wall extending vertically downwardly from said top surface to a first bend extending away from said back wall, to a second bend extending away from said back wall, whereby an angle of approximately 90.degree. is formed by said first and second bends; said second bend extends into a third bend extending towards said back wall through an angle of approximately 135.degree., said third bend defining a pocket; said third bend extends into a fourth bend extending away from said back wall through an angle of approximately 45.degree. and approximately vertically into said trough by a distance of at least one half of said trunnion radius, said trough having a width slightly larger than twice said trunnion radius; and(iv) said retaining wall being parallel to at least a portion of said groove back wall, the distance from said retaining wall to said trough being substantially equal to the distance from one of said trunnions to said outer surface of said upper panel, and the distance from said retaining wall to said pocket being substantially equal to the distance from said one of said trunnions to said outer surface of said lower panel;whereby when said platform is mounted to said brackets, said platform is movable between a first position and a second position, so that when said platform is in said first position, each of said trunnions is placed in a respective one of said pockets, said lower panel outer surface abuts said retaining wall, and said upper panel is maintained in a horizontal position; and when said platform is in said second position, each of said trunnions is placed in a respective one of said troughs, said upper panel outer surface abuts said retaining wall, and said upper panel is maintained in a vertical position, thereby allowing said platform to be detached from said brackets by lifting said trunnions out of said groove openings.
