Abstract:
A cable actuated emergency stop system comprising:a housing structure; a first shaft slideably disposed within said housing structure, said first shaft being movable relative to said housing structure along a first path in a direction substantially parallel to an axial centerline of said first shaft in response to a first force exerted by at least one first cable attached to an end of said first shaft; a second shaft slideably disposed within said housing structure, said second shaft being movable relative to said housing structure along a second path in a direction substantially parallel to an axial centerline of said second shaft, and opposite movement of said first shaft, in response to a second force exerted by at least one second cable attached to an end of said second shaft; a first cam structure having a first opening formed therethrough, said first opening being shaped to receive said first shaft therein in slideable relation with said first cam structure; a second cam structure having a second opening formed therethrough, said second opening being shaped to receive said second shaft therein in slideable relation with said second cam structure; a switch operator that is movable along a second path between at least a first position and a second position in response to movement of said first or second cam structure in either a first direction or a second direction substantially parallel to said first or second path; and mechanism for locking said switch operator in said second position after said switch operator moves into said second position.
