Abstract
A cable tensioner for adjusting the tension in various cables. It may be used with a variety of cables including those that have flexible members routed through bendable sheaths. The cable tensioner includes a worm gear arrangement located within a housing, where the worm gear takes the form of a worm screw engaged with a spur gear. The spur gear may then be engaged with teeth on a movable sleeve. The end of a cable is secured within the sleeve and the tension in the cable can be adjusted by moving the sleeve via the worm gear.
Claims13
A device for adjusting tension in a cable having an inner flexible member routed through an outer sheath, said device comprising:
- a housing configured for attachment to a fixed structure;
- a sleeve having a channel for receiving an end of an inner flexible member of a cable, said sleeve located at least partially within said housing and configured for moving within said housing, wherein said end of said inner flexible member is secured to said sleeve;
- a set screw for securing said end of said inner flexible member in said channel, said set screw located in said sleeve;
- an inlet collar configured to engage with an end of an outer sheath of said cable, wherein said inlet collar abuts an outside of said housing such that said outer sheath remains outside said housing;
- and
- a worm gear operable to move said sleeve for adjusting tension in said inner flexible member without moving said outer sheath.
A device for adjusting tension in a cable having an inner flexible member routed through an outer sheath, said device comprising:
- a housing;
- an inlet collar configured to engage with an end of an outer sheath of said cable, wherein said inlet collar abuts an outside of said housing such that said outer sheath remains outside said housing;
- a sleeve having a channel for securing an end of an inner flexible member of a cable, said sleeve having a plurality of teeth on an upper surface;
- a spur gear located at least partially within said housing, said spur gear engaged with said plurality of teeth on said upper surface of said sleeve;
- and
- a worm screw located at least partially within said housing, said worm screw having a head extending outside of said housing, said worm screw engaged with said spur gear such that rotation of said worm screw provides movement of said sleeve via said spur gear engaged with said teeth for adjusting tension of said inner flexible member without moving said outer sheath.
