Abstract
A cable actuated emergency stop system is disclosed, which includes a housing structure within which a single shaft assembly can be maintained for engaging a cable and a single shaft assembly that can be attached to the cable, wherein the single shaft assembly comprises only one shaft that is slideably disposed within the housing structure and movable relative to the housing structure a long a single path in a direction parallel to an axial centerline of the shaft in response to a force exerted by the cable attached to at least one end of the shaft. The system is configured in the context of a single directional cable actuated emergency stop device which includes one operating shaft exiting the housing structure.
Claims13
A cable actuated emergency stop system, comprising:
- a housing structure within which a single shaft assembly can be maintained for engaging at least one cable;
- at least one electrical switching mechanism maintained within said housing structure wherein said at least one electrical switching mechanism comprises at least one switch;
- a snap-action mechanism that prevents said at least one electrical switching mechanism from being teased;
- and
- a single shaft assembly that can be attached to said at least one cable, wherein said single shaft assembly comprises only one shaft that is slideably disposed within said housing structure and movable relative to said housing structure along a single path in a direction parallel to an axial centerline of said shaft in response to a force exerted by said at least one cable attached to at least one end of said shaft.
