Patent ID: 7080717

Claim:
An elevator emergency braking apparatus disposed in an elevator apparatus comprising a main rope array including a plurality of main ropes spaced at a distance from each other and arranged side-by-side along a plane from a first rope at a first side of the main rope array to a last rope at a second side of the main rope array, for braking movement of an elevator car by compressing the main rope array, the elevator emergency braking apparatus comprising: a braking device main body having a main body braking surface facing the first side of the main rope array, and a tapered surface facing the second side of the main rope array; an intermediate braking piece disposed within the main rope array, between a mutually-adjacent pair of the main ropes, and in a direction toward the first side of the main rope array, compressing the main rope array during braking; and a wedge member disposed between the tapered surface and the second side of the main rope array, separated from the main rope array during normal operation, and displaced in a longitudinal direction of the main ropes and wedged between the tapered surface and the main rope array during braking, in which the main rope array and the intermediate braking piece are compressed and pressed toward the main body braking surface by the wedge member which is wedged between the tapered surface and the main rope array at the second side of the main rope array.
