Abstract
A tension member for an elevator system includes one or more tension elements extending along a length of the tension member, and one or more a wave guide regions secured to at least one surface of the tension member or integral to the tension member and extending along the length of the tension member. The one or more wave guide regions are configured for transmission of a radio frequency (RF) data signal along the one or more wave guide regions.
Claims15
A tension member for an elevator system, comprising:
- one or more tension elements extending along a length of the tension member;
- and
- one or more a wave guide regions secured to at least one surface of the tension member or integral to the tension member and extending along the length of the tension member, the one or more wave guide regions configured for transmission of a radio frequency (RF) data signal along the one or more wave guide regions;
- wherein the tension member is configured as a belt, the belt including a jacket defining:
- a traction side configured to interact with a drive sheave of the elevator system;
- and
- a back side opposite the traction side;
- and
- wherein the one or more wave guide regions are secured at an edge surface of the belt, the edge surface extending between the traction side and the back side.
A tension member for an elevator system, comprising:
- one or more tension elements extending along a length of the tension member;
- and
- one or more a wave guide regions secured to at least one surface of the tension member or integral to the tension member and extending along the length of the tension member, the one or more wave guide regions configured for transmission of a radio frequency (RF) data signal along the one or more wave guide regions;
- wherein the tension member is configured as a synthetic fiber rope;
- wherein the one or more wave guide regions surround the one or more tension elements.
An elevator system, comprising:
- a hoistway;
- an elevator car movable along the hoistway;
- a tension member operably connected to the elevator car to move the elevator car along the hoistway, the tension member including:
- one or more tension elements extending along a length of the tension member;
- and
- one or more wave guide regions secured to at least one surface of the tension member or integral to the tension member and extending along the length of the tension member, the one or more wave guide regions configured for transmission of a radio frequency (RF) data signal along the one or more wave guide regions;
- wherein the tension member is configured as a belt, including a jacket including:
- a traction side configured to interact with a drive sheave of the elevator system;
- and
- a back side opposite the traction side;
- wherein the one or more wave guide regions are secured at one of the back side or an edge surface of the belt, the edge surface extending between the traction side and the back side.
