ABSTRACT:
A can crusher comprises a bottom plate and a handle that rotate about a first axis. A top plate is slidable along the handle. A link pivotally connects the top plate to a second axis offset from the first axis. Rotating the handle and bottom plate tends to revolve the top plate away from the second axis, but the link keeps the top plate at a fixed distance from the second axis by controlling the top plate to slide along the handle toward the bottom plate. A can or other object placed between the top and bottom plates is crushed between them as the handle rotates. The handle normally rotates from a vertical attitude toward a horizontal attitude during the crushing operation. The handle and bottom plate can rotate to a stable rest configuration below the first axis.
