Abstract: A track start wedge includes a housing, a ratchet gear assembly, and a locking pawl assembly. The ratchet gear assembly is disposed at least partially within the housing and includes a bar, a pinion gear at each end of the bar, and a ratchet gear between the ends of the bar. The locking pawl assembly is coupled to the housing and includes a locking pawl disengageably coupled to the ratchet gear and a spring operable to bias the locking pawl into engagement with the ratchet gear. The ratchet gear assembly is configured to rotate in unison in a first direction toward a front of the housing and a second direction toward a rear of the housing, but the locking pawl prevents rotation of the ratchet gear in the second direction when the locking pawl is engaged with the ratchet gear.

Abstract: Various embodiments include a system that provides assisted access to a pool. The system includes a platform that includes a frame, a deck, and one or more handrails. The deck is attached to the frame and sized to receive a wheelchair. The one or more handrails are attached to at least one of the frame and the deck. The system includes an upright lifting component case. The frame of the platform is substantially perpendicular to the upright lifting component case. The system includes lifting components that are at least partially disposed in the upright lifting component case and attached to the platform. The lifting components are operable to vertically move the frame between a top and a bottom of the upright lifting component case. The system includes an electrical power source operable to provide electrical power to at least a portion of the lifting components.

Abstract: A starting block lock having a clamp, top and bottom locking wedges, and a rod is provided. The clamp includes top and bottom portions each having an inside surface and a body between the top and bottom portions. The body includes a cylindrical bore extending on a longitudinal axis between the top and bottom portions. The top and bottom locking wedges each include an outer surface, an inner surface, a side surface, and an aperture extending between and through the outer and inner surfaces. At least a portion of each of the side surfaces slidably contact the inside surface of the clamp. The rod extends through the apertures and the cylindrical bore and is configured rotate in a first direction to linearly displace the top and bottom locking wedges toward each other thereby providing an outward force against the inside surfaces of the clamp to expand the clamp.
