Universal crossbar head for engaging beltrails

Claim 1

A universal head structure for a crossbar of a freight-retaining system including belt rails mounted on opposite side walls of a load-carrying chamber having various different configurations requiring different connections between the head structure and the belt rails, wherein the improvement comprises a. a hollow housing adapted to be connected to the end of an elongated crossbar, b. said housing providing a substantially flat front wall extending perpendicularly to the longitudinal plane of the crossbar, c. a pair of fixed hook members carried by said housing projecting frontwardly and downwardly from said front wall, d. a first means slidably mounted in said housing and providing a portion movable through an opening in said front wall so as to cooperate with said hook members to releasably connect the crossbar to a belt rail providing a horizontal flange having vertically directed openings formed therein, e. a second means slidably mounted in said housing providing a pair of locking fingers movable through openings in said front wall in a plane parallel to said first means beneath and outwardly of said hook members so as to cooperate independently of said first means with said hook members to releasably connect said crossbar to a belt rail having a raised retaining lip and a spaced angularly directed opening, f. and a third means slidably mounted in said housing providing a pair of retaining pins movable through openings formed in said front wall in a spaced parallel plane with respect to said locking fingers of said second means so as to cooperate independently of said first and second means with said hook members to releasably connect the crossbar to a belt rail providing a substantially horizontally directed opening.
