Locking handle

A locking handle assembly comprising a gudgeon, a roll pin, a piston defining a piston axis, a spring, and a handle, wherein:

• the roll pin is operably attached to the gudgeon so that the roll pin cannot translate relative to the gudgeon;
• the piston is operably attached to the roll pin so that the piston can rotate about the roll pin but cannot otherwise translate relative to the roll pin or the gudgeon;
• the handle defines a blind bore substantially aligned with the piston axis;
• the spring and a portion of the piston are arranged within the blind bore so that the spring biases the handle relative to the piston toward the gudgeon along the piston axis;
• the handle is configured to transition between a first locked state and an unlocked state by translating relative to the piston along the piston axis;
• when the handle is in the first locked state:
• (a) a chamfered end of the handle is held in contact with a first divot, the first divot being defined by the gudgeon and being sized and shaped to mate with the chamfered end;
• and
• (b) the chamfered end is held in contact with the first divot by the bias of the spring acting along the piston axis such that interference of the chamfered end with the first divot substantially prevents the handle, the piston and the spring from rotating relative to the gudgeon;
• and
• when the handle is in the unlocked state:
• (a) the handle is farther from the gudgeon along the piston axis than in the locked state so that the chamfered end of the handle is clear of the first divot, thereby allowing the handle, the piston and the spring to rotate relative to the gudgeon;
• (b) the handle is urged along the piston axis by the bias of the spring;
• and
• (c) the spring is more compressed along the piston axis in the unlocked state than in the locked state.
