Patent AT-E400406-T1: [Translated] REVERSIBLE RATCHET TOOL WITH IMPROVED PAWL

A ratcheting tool (10) includes a body and a gear (48) disposed in the body. The gear defines a plurality of concave teeth (52) on a circumference of the gear so that the gear teeth define a first arc having a first radius (R1). A pawl (94) is disposed in the body so that the pawl is movable laterally with respect to the gear between a first position, in which the pawl is disposed between the body and the gear so that the body transmits torque through pawl in a first rotational direction, and a second position, in which the pawl is disposed between the body and the gear so that the body transmits torque through the pawl in an opposite rotational direction. The pawl defines a plurality of convex teeth facing the gear. A first arc extends between opposite axial ends of the gear and is defined by the gear's concave center area and a second arc between opposite sides of the pawl face and is defined by the pawl's convex center area, wherein a first radius (700) defined by the first arc is greater than a second radius (702) defined by the second arc.
