Claim:
A bracket assembly for removable attachment to a rail having an aperture, a front surface, and a back surface, the bracket assembly comprising: a bracket having a longitudinal track assembly having a first right angle flange at a first end thereof; a rail engagement element on the first flange, configured and located so as to enter the aperture in the rail when the first flange is disposed adjacent the front surface of the rail; a carrier having a longitudinal slot and a second right angle flange at a first end thereof, the carrier being slidably mounted on the longitudinal track assembly by means of a stud extending from the track assembly into the slot for relative longitudinals sliding movement thereon between a first position in which the second flange is proximate the first end of the longitudinal track and a second position in which the second flange is displaced away from the first end of the longitudinal track assembly; and a biasing element coupling the carrier to the longitudinal track assembly so as to bias the second flange toward the first position so as to secure the rail between the first and second flanges, with the rail engagement element being configured for entry into the aperture.
