Referring now to FIGs. 1A and 1B, each of the locking mechanisms 110 may further have a detent mechanism that tends to urge its rotatable structure 112 to move fully into the unlocked orientation or the locked orientation. As used herein, a "detent" refers to an apparatus, instrument, structure, device, component, feature, system, mechanism, assembly, or module structured, organized, configured, designed, arranged, or engineered to resist or arrest the motion or rotation of a wheel, axle, spindle, or other structure. (Search 'detent' on Wikipedia.com June 22, 2020. Modified. Accessed March 19, 2021.) In certain embodiments, the detent continues to resist or arrest the motion or rotation while in an engaged configuration and permits the motion or rotation when in a disengaged configuration. Examples of a detent may include a single structure or a combination of structures cooperating to serve as a detent. Examples of a detent and/or detent assembly include but are not limited to a ratchet and pawl, a nub or bump and a recess, a recess and a raised or extending structure, a notch and a pin, a set of notches or recesses in a smooth structure and a set of corresponding nubs, latches, pins, spring loaded ball bearings, or the like. In one embodiment, a detent may comprise an ear of a rotatable structure and a groove, niche, notch, or carve-out of another structure.
