Abstract: A device for a friction force provider for an emergency safety actuator for an elevator is disclosed. The friction force provider may include a housing having a first end and an opposing second end, where the first end may define an opening. The friction force provider may further include a primary magnet positioned within the housing and configured to move between an armed position and a working position. The primary magnet may be configured to create a force on a rail of an elevator system in the working position and be held within the housing in the armed position.

Abstract: A safety chain circuit includes a plurality of protection devices connected between a first chain end and a second chain end, and an amplifier. The amplifier includes a first device switch and a second device switch connected between an input and an output, a first enabling switch connected between the second chain end and a second enabling switch, and a first control switch and a second control switch. The first enabling switch selectively enables the first control switch to control the first device switch. The second enabling switch selectively enables the second control switch to control the second device switch. The first control switch, when enabled, selectively controls the first device switch in response to receiving a first control signal. The second control switch, when enabled, selectively controls the second device switch in response to receiving a second control signal.

Abstract: An exemplary power supply includes a low side switch and a high side switch. A driver controls operation of the high side switch. A bootstrap capacitor supplies power to the driver. An energy storage portion is in parallel with the bootstrap capacitor to provide control over whether a voltage of the bootstrap capacitor drops below a desired voltage. A voltage regulator is in parallel with the bootstrap capacitor for limiting current provided to the bootstrap capacitor and for regulating a voltage of the bootstrap capacitor.

Abstract: An exemplary elevator system comprises a machine support (30) including a first portion (32) situated in a generally horizontal position at least partially within a hoistway (24). A second portion (34) is oriented generally perpendicular to the first portion. The second portion has one end supported by a support surface (52) adjacent the hoistway such that a portion of a load of the machine support is transferred to the support surface. One end of the first portion (32) is supported by the second portion (34) and another end of the first portion is supported by a structural member at least partially in the hoistway such that a remainder of the load of the machine support is transferred to the structural member.

Abstract: An elevator system is provided, comprising: an elevator car; a driving machine to drive elevator car movements; a braking assembly to apply a braking force in opposition to the elevator car movements; and a control system (301) configured to control a deceleration rate during an incident requiring engagement of at least one of primary and secondary brakes to decelerate the elevator car movements by: operating the driving machine or the braking assembly as the primary brake, determining whether the deceleration rate is within a target range, and adjusting the deceleration rate in an event the deceleration rate is outside the target range.

Abstract: A brake (26) for machine (16) and method of using the brake (26) is disclosed. The brake (26) may comprise first and second brake linings (38) configured to be frictionally engageable with a rail (14), a first biasing member (34) configured to urge the first brake lining (38) to engage the rail (14), and a first actuator (30) configured to move the first brake lining (38) to disengage the rail (14) when the first actuator (30) is energized. The first actuator (30) comprises a backing block (44), a first solenoid (46) housed in the backing block (44), and a first armature (48) disposed between the solenoid (46) and the first brake lining (38), wherein an end (56) of the first armature (48) is sloped toward the backing block (44). The brake (26) may be configured to be mounted on a machine (16), floor or the like.

Abstract: A method of avoiding inadvertent resetting of a safety brake (20) of an elevator system (12), the method comprising: obtaining data with at least one sensor associated with an electronic safety actuator (22); and determining whether resetting of a safety brake (20) is made based on an algorithm that compares the data obtained by the sensor(s) and a threshold condition, resetting of the safety brake (20) occurring if the threshold condition is exceeded for equal to or greater than a predetermined amount of time.

Abstract: An elevator system control system (301) is provided and includes a sensor system (302) configured to sense elevator car conditions, a safety system signaling element (303) to generate a safety signal indicative of an incident and a control system (310) configured to react to the safety system signal. When the control system (310) receives the safety signal indicating that an incident has occurred that requires engagement of at least one of primary and secondary brakes, the control system (310) controls a deceleration rate during the incident by operating the primary brake, determining whether the deceleration rate is within a target range and adjusting the deceleration rate based on signals from the sensor system.

Abstract: A braking device is operable to aid in braking a hoisted object relative to a guide member. The braking device includes a mounting structure connected to the hoisted object, and first and second brake pads positioned on the mounting structure on opposing sides of a passageway through which the guide member extends. The first and second brake pads each include a contact surface that is operable to frictionally engage the guide member. The second brake pad engages the mounting structure in a manner that enables the second brake pad to move relative to the mounting structure between a non-braking position and a braking position. The braking device includes a brake initiator that is selectively operable to initiate movement of the second brake pad from the non-braking position toward the braking position by selectively actuating an actuatable portion of the brake initiator from a non-deployed position to a deployed position.
