Abstract
An elevator drive cassette configured for use in driving the movement of an elevator car along a rail or rack, the elevator drive cassette including: a driven pinion and drive shaft configured to be driven by a drive motor associated with the elevator car; a mechanical coupling; at least one further pinion configured to be driven by the driven pinion or drive shaft via the mechanical coupling, wherein both the driven pinion and at least one further pinion are configured to engage the same rail or rack.
Claims21
An elevator drive cassette configured for use in driving the movement of an elevator car along a rail or rack, the elevator drive cassette including:
- a driven pinion and drive shaft configured to be driven by a drive motor associated with the elevator car;
- a mechanical coupling;
- at least one further pinion configured to be driven by the driven pinion or drive shaft via the mechanical coupling, wherein both the driven pinion and at least one further pinion are configured to engage the same rail or rack.
An elevator drive cassette configured for use in driving the movement of an elevator car along a rail or rack, the elevator drive cassette including:
- a bearing block;
- one or more linear bearings supported by the bearing block and configured to support the passage of the rail or rack therethrough.
An elevator system including:
- an elevator car with a transportation compartment;
- a rack or rail along which the elevator car is configured to be driven;
- and
- an elevator drive mechanism configured to drive the elevator car along the rack or rail, wherein the elevator drive mechanism includes at least one elevator drive motor and at least one elevator drive cassette configured for use in driving the movement of the elevator car along the rail or rack, the elevator drive cassette including:
- a driven pinion and drive shaft configured to be driven by the at least one drive motor;
- a mechanical coupling;
- at least one further pinion configured to be driven by the driven pinion or drive shaft via the mechanical coupling, wherein both the driven pinion and at least one further pinion are configured to engage the same rail or rack.
A brush for contacting a conductor for the transfer of electrical power, the brush including:
- a brush member formed from an electrically conductive material;
- a first biasing stage configured to bias the brush member in a first direction;
- and
- a second biasing stage configured to bias the first biasing stage in the first direction.
An elevator fire seal system, the system including:
- a cable spool mountable to an elevator car and configured to collect and release a cable;
- and
- a fire seal member mountable to the elevator car and suspended by the cable, such that release of the cable from the cable spool permits movement the fire seal away from the elevator car and collection of the cable by the cable spool moves the fire seal towards the elevator car.

An elevator system including:
- an elevator car with a transportation compartment;
- a rack or rail along which the elevator car is configured to be driven;
- an elevator drive mechanism configured to drive the elevator car along the rack or rail, wherein the elevator drive mechanism includes at least one elevator drive motor and at least one elevator drive cassette configured for use in driving the movement of the elevator car along the rail or rack, the elevator drive cassette including:
- a driven pinion and drive shaft configured to be driven by the at least one drive motor:
- a mechanical coupling;
- at least one further pinion configured to be driven by the driven pinion or drive shaft via the mechanical coupling, wherein both the driven pinion and at least one further pinion are configured to engage the same rail or rack;
- and an elevator fire seal system, the system including:
- a cable spool mountable to the elevator car and configured to collect and release a cable;
- and
- a fire seal member mountable to the elevator car and suspended by the cable, such that release of the cable from the cable spool permits movement the fire seal away from the elevator car and collection of the cable by the cable spool moves the fire seal towards the elevator car.
