A ratchet assembly includes an elongated shaft, a gear housing, a ratcheting member, and an arm. The elongated shaft can have a gear and be supported by the gear housing to allow rotation about a primary axis of the shaft. The ratcheting member can mount in the housing and be biased toward the gear to engage with the gear hindering relative rotation about the shaft axis in a first direction and allowing rotation about the shaft axis in a second direction opposite the first direction. The ratcheting member can rotatably mount within the housing about a se...
1. A ratchet assembly comprising: a housing;an articulating element rotatably coupled to the housing at a first axis of rotation;an elongated shaft comprising a threaded portion in operative contact with the housing and the articulating element such that rotation of the elongated shaft causes rotation of the articulating element with respect to the housing, the elongated shaft further comprising a first ratchet portion; anda rotation body mounted on the elongated shaft and comprising a second ratchet portion in operative contact with the first ratchet po...
