Definitions

  • At least one catch is formed close to one terminal end of the concave brim of the crescent-shaped pawl and is adapted to interlock with teeth of the ratchet member, permitting the ratchet member to rotate only in the direction of the opposite terminal end of the concave brim of the crescent-shaped pawl.
  • a bean-shaped hole, into which a fixed cylindrical pin is fitted, is formed in substantially middle portion of the crescent-shaped pawl substantially concentrically with the concave brim of the crescent-shaped pawl.
  • a constant pull is given by some means at substantially middle point of the convex rim of the crescent-shaped pawl toward the center of the ratchet member.
