1. A lockable rooftop carrier clamp comprising;
a locking post fixed to a first substrate, the locking post having a frusto-conical plunger tapering at its first end and connected to a cylindrical stem at its base or second end, with the diameter of the cylindrical stem being smaller than the diameter of the base, with a first end of the stem attached to the base of the cone and a second end of the stem connected to the first substrate,
a clamp housing fixed to a second substrate, the housing having a first bore defining a first axis with a first open end adapted to accept the locking post in a captured or uncaptured condition, the clamp housing also having a second blind bore defining a second axis orthogonal to the first axis, the second bore extending through a side wall of the clamp housing,
a bolt positioned in the first bore to slide transversely to the first axis therein, the bolt being biased inwardly and adapted to capture the locking post as the locking post moves past the bolt from its first end to its second end, the bolt also having an arm,
a rotor also located in the first bore, the rotor having a bore along the first axis adapted to accept the conical portion of the locking post when it is inserted into the first end of the clamp housing first bore, the rotor also having a cam shaped exterior wall adapted to contact the arm of the bolt so that when the rotor is pivoted from a captured condition to an uncaptured condition about the first axis, the exterior wall moves the bolt transversely outwardly against the bias and away from the locking post, the rotor also having a locking pin extending outwardly from the rotor exterior,
a release lever operatively connected to the rotor and extending from the rotor transverse to the first axis to a location outside the clamp housing for pivoting the rotor about the first axis from an uncaptured to a captured condition and from a captured to an uncaptured condition,
a hollow generally cylindrical lock housing fixed in the second blind bore having lock housing bore and a pair of longitudinal splines and adapted to receive a core having a plurality of tumblers variously biased into the splines and retracted from the splines in the presence of an appropriate key to allow the core to rotate in the bore from a locked to an unlocked condition along the second axis, the core having a keyway at a first end for accepting a key and an adapter at the opposite second end, with the adapter interfering with the locking pin when the core is in the locked condition so that the rotor cannot pivot, and allowing pivoting of the rotor about the first axis by the release lever while the core is in the unlocked condition.
