An automatic lock mechanism is provided for locking adjustable frame system components together. A locking mechanism includes a locking pin having a shaft, a head and a biasing spring cooperates with a stud and slot locking mechanism. A stud is inserted into a slot, for example, a teardrop shaped slot, and then moved to the direction of insertion. The locking pin then extends into slot, preventing inadvertent upward movement of the horizontal member.

[ I claim:] [1.] An adjustable frame system comprising:a first frame component including a row of spaced apart slots;a second frame component including a plurality of studs extending from the second frame component in a first direction, the studs being adapted for insertion in the first direction into the slots to a first position and movement in a second direction orthogonal to the first direction from the first position to a second position;a locking pin coupled to the second frame component, the locking pin movable between an extended position where the locking pin extends past an edge of the second frame component and a retracted position where the locking pin does not extend past the edge of the second frame component;a housing that couples the locking pin to the second frame component; anda spring coupled to the locking pin to bias the locking pin to the extended position,wherein the locking pin includes a head coupled to a shaft, the shaft having an end distal from the head, the housing including a first end, a second end, and a cavity between the first and second ends, the housing being coupled to the second frame component adjacent the first end of the housing, the locking pin head being positioned outside the second end of the housing, and the distal end of the shaft being inside the cavity of the housing in the retracted position and extending outside the first end of the housing in the extended position.
