Abstract
An elevator safety device comprises a housing attachable to an elevator car or to an elevator counterweight of an elevator system, the housing comprising a passage for allowing a guide member to pass through. A brake shoe is attached to the housing and is located on a first side of the guide member. A support element is arranged on a second of side of the guide member, the support element extending at an angle with respect to the guide member, thereby defining a tapered region between the guide member and the support element. A movable braking element is rotatable around a rotation axis of the movable braking element. The movable braking element is, at least in an activated condition of the elevator safety device, arranged within the tapered region defined by the support element and the guide member. The movable braking element is capable of rotatingly moving along the support element into a wedged condition between the support element and the guide member. The movable braking element has, in a plane that is oriented perpendicularly to the rotation axis, a non-circular cross-section, which is defined by a closed curve having a constant width.
