Abstract
A termination device for a suspension member of an elevator system includes a housing and a wedge located in the housing. The wedge extends across a width of the suspension member and at least partially across a thickness of the suspension member. The wedge is interactive with the suspension member to apply a clamping force to the suspension member in response to an axial load acting on the suspension member. The wedge includes a wedge lip configured to contain the suspension member within a lateral extent of the wedge.
Claims10
A termination device for a suspension member of an elevator system comprising:
- a housing;
- and
- two opposing wedges disposed in the housing and configured such that the suspension member is receivable therebetween, each wedge extending across a width of the suspension member and at least partially across a thickness of the suspension member, each wedge interactive with the suspension member to apply a clamping force to the suspension member in response to an axial load acting on the suspension member, each wedge including a wedge lip disposed at a lateral end of each wedge configured to contain the suspension member within a lateral extent of each wedge by at least partially overlapping a lateral end of the suspension member;
- wherein a first wedge lip of a first wedge of the two opposing wedges is configured to overlap a second wedge lip of a second wedge of the two opposing wedges.
A termination assembly of a belt for an elevator system, comprising:
- the belt including:
- a plurality of tension members extending along a length of the belt;
- and
- a jacket at least partially enclosing the plurality of tension members;
- a termination device including:
- a housing;
- and
- two opposing wedges disposed in the housing such that the belt is disposed between the two opposing wedges, each wedge extending across a lateral width of the belt and at least partially across a thickness of the belt, each wedge interactive with the belt to apply a clamping force to the belt in response to an axial load acting on the belt, each wedge including a wedge lip disposed at a lateral end of each wedge configured to contain the belt within a lateral extent of each wedge by at least partially overlapping a lateral end of the belt;
- wherein a first wedge lip of a first wedge of the two opposing wedges is configured to overlap a second wedge lip of a second wedge of the two opposing wedges.
An elevator system comprising:
- a hoistway;
- an elevator car disposed in the hoistway;
- a belt operably connected to the elevator car to suspend and/or drive the elevator car along the hoistway;
- and
- a termination device disposed in the hoistway and operably connected to a belt end of the belt, the termination device including:
- a housing;
- and
- two opposing wedges disposed in the housing such that the belt is disposed between the two opposing wedges, each wedge extending across a lateral width of the belt and at least partially across a thickness of the belt, each wedge interactive with the belt to apply a clamping force to the belt in response to an axial load acting on the belt, each wedge including a wedge lip disposed at a lateral end of each wedge configured to contain the belt within a lateral extent of each wedge by at least partially overlapping a lateral end of the belt;
- wherein a first wedge lip of a first wedge of the two opposing wedges is configured to overlap a second wedge lip of a second wedge of the two opposing wedges.
