Abstract

Embodiments here are directed to an elevator stabilizing assembly for energy dissipation of an elevator assembly is provided. The elevator stabilizing assembly includes an actuator and a stabilizing device. The actuator is configured to move between a retracted position and an extended position. The stabilizing device includes an arm and a biasing member. The biasing member is coupled to the arm and biases the arm to move the arm between a disengaged position and an engaged position. When the actuator is in the extended position, the arm is moved into the engaged position when at least a portion of the arm is in contact with the fixed member of a hoistway. When the actuator is in the retracted position, the arm is moved into the disengaged position such that the at least the portion of the arm is free from contact with the fixed member of the elevator assembly.

Dependent claims

An elevator stabilizing assembly for dissipating energy of an elevator assembly, the elevator assembly having an elevator cab, a plurality of suspension members, and a fixed member of a hoistway, the plurality of suspension members move the elevator cab between a plurality of positions and the fixed member guides the elevator cab within the hoistway between the plurality of positions, the elevator stabilizing assembly comprising:

an actuator configured to move between a retracted position and an extended position;
and
a stabilizing device having:
an arm having a sidewall;
a spacer coupled to the sidewall of the arm;
and
a biasing member coupled to the arm and configured to bias the arm,
wherein, when the actuator is moved into the extended position, the biasing member causes the arm to be biased in a direction against the fixed member such that at least a portion of the arm is in contact with the fixed member of the elevator assembly, and when the actuator is moved from the extended position to the retracted position, the arm is moved such that the at least the portion of the arm is free from contact with the fixed member of the elevator assembly and is held in a predetermined position by the biasing member and the spacer.

An elevator stabilizing assembly for damping movement of an elevator cab of an elevator assembly, the elevator assembly having the elevator cab, a plurality of suspension members from which the elevator cab is suspended, and a fixed member of a hoistway, the plurality of suspension members move the elevator cab between a plurality of positions and the fixed member guides the elevator cab within the hoistway between the plurality of positions, the elevator stabilizing assembly comprising:

an actuator configured to move between a retracted position and an extended position;
and
a stabilizing device having:
a pair of arms pivotally biased by a biasing member positioned between the pair of arms and to maintain a predetermined spacing between the pair of arms;
and
a pair of engaging members, one of the pair of engaging members coupled to one of the pair of arms and the other one of the pair of engaging members coupled to the other one of the pair of arms,
wherein, the elevator stabilizing assembly is configured to move between an unstabilized state where the actuator is in the retracted position such that the pair of engaging members are held in a position spaced apart from one another by the biasing member, and a stabilized state where the actuator is in the extended position and where the biasing member causes each of the pair of arms to be biased in a direction against the fixed member such that at least a portion of the pair of engaging members is in contact with the fixed member of the elevator assembly.
