Abstract

The ratchet mechanism comprises a head portion with a circular central housing, the inner surface adjoining the handle portion having a further recess characterized by a plurality of engagement ramp profiles arranged not unlike low angled gear teeth within the recess arc. A pawl is located within the recess, with a corresponding plurality of engagement ramp profiles abutting the recess engagement ramp profiles and incorporating an inner facing toothed face of similar corresponding pitch and profiles as the drive element teeth in order that they can mechanically mesh into one another when ratchet is operated in the drive direction, the pawl inward force being substantially evenly distributed along the pawl toothed front face by the use of several similar engagement ramp profiles urging all the pawl teeth into the required locking engagement with the drive element simultaneously.
