ABSTRACT:
A locking system has a side frame having an open end and a spring-loaded hanger release insert extending therefrom. The system also has a hanger body having an upper portion with a terminal end. A hanger pivot fitting extends generally downwardly from the upper portion of the terminal end. A hanger locking surface extends outwardly from the terminal end. The spring-loaded hanger release insert has an upturned mating surface and the hanger locking surface has a downturned mating surface compatible with the upturned mating surface. A hanger release arm is interconnected with the spring-loaded hanger release insert. The system may further include a hanger brace extending from the hanger body, having an alignment guide at an end of the hanger brace. The hanger locking surface may have an angled, generally outwardly-extending face with a step, and the hanger release insert may have an angled, generally outwardly-extending face with a step, each of the steps defining a mutually-compatible mating surface. The side frame may further include a hanger support block extending from the side frame and adapted to support the hanger brace when the hanger brace is locked onto the side frame. The side frame may comprise a top, a bottom, a first side and a second side. The side frame may further comprise a hanger plate extending between the top and the first side. The hanger release arm is then connected to the hanger plate. The side frame comprises a tube, and a portion of the hanger release insert is secured within the tube. A compression spring or other biasing mechanism is secured within the tube to provide compression force against the hanger release insert. The locking surface may be a portion of a side frame locking piece, the hanger comprising a tube. A portion of the locking piece may be secured within the tube, the locking surface extending out of the tube.
