Abstract
An apparatus for controlling the rotation of a gear comprising rotating a cam which causes the linear movement of a rod to control the rotation of the gear, wherein the cam rotates within a confined space but not around a fixed axle. The apparatus is particularly useful for controlling the opening and closing movements of a handcuff whose operating elements are comprised of a swing arm and at least one gear having teeth which engage the teeth of the swing arm.
Claims14
An apparatus comprised of at least a first gear, a swing arm, a control rod, and a rod cam wherein:
- said first gear is rotatably attached to a first axle which is perpendicularly affixed to a planar base, said first gear is adapted to rotate around said first axle in a plane parallel to said planar base and is equipped with a first set of teeth;
- said swing arm is rotatably attached to said planar base and is adapted to rotate in a plane parallel to said planar base, said swing arm is equipped with a second set of teeth adapted for intermeshing contact with said first set of teeth;
- said control rod is slidably mounted on said planar base, and is adapted to control the rotation of said first gear around said first axle;
- said rod cam is comprised of a cam plate and a cam shaft, wherein
- said cam plate is substantially circular in shape, and includes a top surface, a bottom surface and shoulder means, said cam plate is rotatably positioned within a substantially circular cam space abutting said planar base and is adapted to rotate within said cam space in a plane parallel to said planar base, wherein said shoulder means is adapted to contact and cause said control rod to linearly slide on said planar base upon rotation of said cam plate,
- said cam shaft perpendicularly extends from said top surface and said bottom surface of said cam plate at the center of said cam plate through a key hole formed in said planar base and is adapted to cause said cam plate to rotate within said cam space.
