Abstract
A brake mechanism comprises a housing, a first handle, a first shaft mounted in the housing having at least one gear rotatably received thereon, a second gear rotatably mounted in the housing in operative engagement with the first shaft, a locking mechanism, and a clutch operatively disposed between the first handle and the second gear, where the clutch defined a recess therein. The locking mechanism comprises a second shaft mounted in the housing, a second handle rotationally fixed to the second shaft, a pawl rotatably received on the second shaft and in operative engagement with the first gear, and said pawl having a first portion in operative engagement with the first gear and a second portion operatively engaged with the clutch. The clutch is moveable between a first position in which the first shaft is rotationally coupled to the second gear and a second position in which the second gear rotates with respect to the first shaft and the pawl second portion is received in the clutch recess.
