Abstract
A termination device for a suspension member of an elevator system includes a housing including a socket defined by two face plates and two side plates. At least one of the face plates and at least one of the side plates are integrally formed. A wedge is receivable within the socket with the suspension member. The wedge is configured to cooperate with the housing to apply a clamping force to the suspension member in response to an axial load acting on the suspension member.
Claims12
A termination device for a suspension member of an elevator system comprising:
- a housing including a socket defined by first and second face plates and first and second side plates, wherein the first side plate is longer than the second side plate, wherein the first and second face plates are arranged opposite one another and the first and second sides plates extend between the first and second face plates, the first and second side plates being arranged opposite one another,
- wherein the first and second face plates and the first side plates are formed from a single piece on a first side of the housing, and the second side plate is coupled to the first and second face plates on a second side of the housing that opposes the first side of the housing so that the first and second face plates and the first side plate therebetween form a U-shaped configuration;
- and
- a wedge receivable within the socket with the suspension member, wherein the wedge is configured to cooperate with the housing to apply a clamping force to the suspension member in response to an axial load acting on the suspension member,
- wherein:
- the second side plate forms a flat plate without defined openings and with plate tabs extend outwardly in opposing directions from opposing side edges of the flat plate;
- and
- each of the first and second face plates defines a plurality of plate openings at the second side of the housing, and the plurality of plate tabs are insertable into respective ones of the plurality of plate openings for securing the second side plate to the housing;
- and
- a rod, configured to connect the termination device to a building structure, is connected the first and second face plates at the first side of the housing and aligned with the first side plate.

An elevator system comprising:
- a hoistway associated with a building structure;
- an elevator car disposed in the hoistway;
- a suspension member 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 an end of the suspension member, the termination device including:

- wherein the first and second face plates and the first side plates are formed from a single piece on a first side of the housing, and the second side plate is coupled to the first and second face plates on a second side of the housing that opposes the first side of the housing so that the first and second face plates and the first side plate therebetween form a U-shaped configuration;
- and
- a wedge receivable within the socket with the suspension member, wherein the wedge is configured to cooperate with the housing to apply a clamping force to the suspension member in response to an axial load acting on the suspension member,
- wherein:
- the second side plate forms a flat plate without defined openings and with plate tabs extending outwardly in opposing directions from opposing side edges of the flat plate;
- and
- each of the first and second face plates defines a plurality of plate openings at the second side of the housing, and the plurality of plate tabs are insertable into respective ones of the plurality of plate openings for securing the second side plate to the housing;
- and
- a rod, configured to connect the termination device to a building structure, is connected the first and second face plates at the first side of the housing and aligned with the first side plate.

A method of manufacturing a termination device comprising:
- contouring a piece of material associated with at least two sides of a housing;
- bending the piece of material to form a first piece;
- and
- coupling a second piece to the first piece to form the housing wherein:
- the housing includes first and second face plates and first and second side plates, wherein the first side plate is longer than the second side plate, wherein the first and second face plates are arranged opposite one another and the first and second sides plates extend between the first and second face plates, the first and second side plates being arranged opposite one another,
- the first and second face plates and the first side plates are formed from a single piece on a first side of the housing, and the second side plate is coupled to the first and second face plates on a second side of the housing that opposes the first side of the housing so that the first and second face plates and the first side plate therebetween form a U-shaped configuration;
- the second side plate forms a flat plate without defined openings and with plate tabs extending outwardly in opposing directions from opposing side edges of the second flat plate;
- each of the first and second face plates defines a plurality of plate openings at the second side of the housing, and the plurality of plate tabs are insertable into respective ones of the plurality of plate openings for securing the second side plates to the housing,
- a rod, configured to connect the termination device to a building structure, is connected the first and second face plates at the first side of the housing and aligned with the first side plate, and
- wherein bending the piece of material further comprises:
- forming a first bend to define the first face plate integrally formed with the first side plate;
- and
- bending the piece of material further comprises forming a second bend to define the second face plate integrally formed with the first side plate, the first face plate and the second face plate being disposed on opposite ends of the first side plate.
