Patent ID: 7513348

Claim:
A one-way drive device, comprising: (a) a first member mounted for rotation about a given axis and defining (i) a first planar surface normal to said axis and (ii) a first shoulder within said first planar surface, said first member being integrally stamp formed into a single unit (b) a second member mounted for rotation about said given axis and defining (i) a second planar surface which is positioned in close proximity to and in confronting relationship with said first planar surface and (ii) a second shoulder within said second planar surface, said second member being integrally stamp formed into a single unit; and (c) a coupling arrangement including at least one strut movable between (i) a first position so as to allow said first member to rotate about said axis in one direction relative to the second member and (ii) a second position in simultaneous engagement with said first and second shoulders so as to prevent said first member from rotating about said axis in the opposite direction relative to said second member; (d) wherein said integrally stamp formed first member includes at least one pocket having a closed underside integrally stamp formed into the first planar surface so as to define said first shoulder, wherein said integrally stamp formed second member includes at least one notch having a closed underside integrally stamp formed into the second planar surface so as to define said second shoulder, and wherein said strut is disposed at least partially within said pocket for movement between said first and second positions; and (e) wherein said second shoulder and the second planar surface of said second member together define an outer edge having a radius of curvature no greater than about 0.030 inch, and said second planar surface has a stamped groove therein extending parallel to and in close proximity to the outer edge.
