Patent ID: 7100882

Claim:
A tram-rail and sliding carriage system for mounting, moving and removing articles substantially by hand under a downwardly facing surface having a front accessible edge comprising: a tram rail arrangement comprising two or more elongated support members attachable to a downwardly facing surface, one of said elongated support members being positioned as the forward load-bearing member and another of said elongated support members being positioned as the rearward load-bearing member, said forward and rearward load-bearing members being oriented substantially parallel to the front accessible edge of said downwardly facing surface, both said forward load-bearing member and said rearward load bearing member being substantially parallel with said downwardly facing surface and both spaced apart a distance sufficient to ensure torquing stability in a state where an engageable sliding carriage and an attached carriage payload is engaged with said load-bearing members and suspended from said load-bearing members; and an engageable sliding carriage having a substantially flat carriage base platform adapted to accept a carriage payload, said base platform having one edge terminating in a first footing dimensioned to slidably engage one of said load-bearing members and a substantially flat engaging plate, parallel with, and slidably attached to, said base platform, said engaging plate terminating at one edge in second footing dimensioned and positioned to slidably engage another of said load-bearing member, and means for moving said engaging plate relative to said base platform; wherein said first and second footings cooperatively engage said tram rail arrangement whereby said engageable sliding carriage and said attached carriage payload are suspended between said forward and said rearward load-bearing members and can be moved laterally to any continuous position on said tram-rail arrangement without being fully disengaged from the track and mounted and removed with all of these manipulations done by hand and without tools.
