Handle adapter and kit for limb differences

A limb differential handle adapter kit, comprising:

• a limb differential handle adapter, including:
• a split coupling mount configured to removably attach to a handle, the split coupling mount including a lower portion having a lower curved channel disposed in an upper surface of the lower portion and an upper portion having an upper curved channel disposed in a lower surface of the upper portion such that as reversibly assembled the lower curved channel and the upper curved channel cooperate to form a coupling conduit having an internal surface configured to contact the handle around a periphery of the handle, the split coupling mount further including a plurality of fasteners spaced along an elongate dimension of the handle configured to reversibly tighten the upper portion to the lower portion;
• a rotational ball-and-socket joint configured to directly and removably attach to and extend from an upper surface of the upper portion of the split coupling mount and be free of direct attachment to the lower portion of the split coupling mount, the rotational joint including a seat portion and a cap portion cooperating to define a socket, a ball interface disposed in the socket, and a shaft extending from the ball interface;
• and
• a differential limb socket configured to receive a differential limb and including at least one replaceable modular insert proportioned to accommodate the differential limb, the at least one replaceable modular insert including a plurality of ventilation features selected from the group consisting of ventilation apertures, ventilation channels, and combinations thereof,
• wherein:
• the limb differential handle adapter is free of locking mechanisms restricting disengagement of the differential limb from the differential limb socket;
• the differential limb socket is attached to the shaft of the rotational joint;
• the kit further includes a plurality of interchangeable components for the at least one replaceable modular insert to adjust for length, diameter, and shape of the differential limb;
• the kit further includes a plurality of shims for disposal between the seat portion and the cap portion of the rotational ball-and-socket joint such friction of the rotational joint is adjustable by incorporation of one or more of the plurality of the shims in the rotational ball-and-socket joint;
• and
• the differential limb socket is attached to the rotational joint via a quick-release connector that is disengageable without use of tools and with a single hand.
