Apparatus and methods for coupling a payload to a support track are
disclosed. In one embodiment, an interface assembly includes a base, a
support arm, and a lug member. The base has a pair of clamp arms
projecting outwardly therefrom. Each clamp arm is adapted to be disposed
through an associated coupling aperture disposed in the engagement
member. The clamp arms are moveable relative to the engagement member
between an unsecured position in which the clamp arms are extractable
from the coupling apertures, and a secured position wherein the clamp
arms are not extractable from the coupling apertures. The support arm is
coupled to the base and to a component (e.g. a payload). The lug member
that locks the assembly in the secured position, is moveable between a
first position wherein the clamp arms are positioned in the unsecured
position, and a second position wherein the clamp arms are positioned in
the secured position.
