Abstract: An illustrative example embodiment of an elevator includes an elevator car frame. A drive mechanism is situated near only one side of the elevator car frame. The drive mechanism includes at least one rotatable drive member that is configured to engage a vertical surface near the one side of the elevator car frame, selectively cause movement of the elevator car frame as the rotatable drive member rotates along the vertical surface, and selectively prevent movement of the elevator car frame when the drive member does not rotate relative to the vertical surface. A biasing mechanism urges the rotatable drive member in a direction to engage the vertical surface. At least one stabilizer is situated near the one side of the elevator car frame and is configured to prevent the elevator car frame from tipping away from the vertical surface.

Abstract: An elevator safety gear assembly for an elevator system comprises a first engagement member; a second engagement member; and a connector mechanically connecting the first and second engagement members with each other. The first and second engagement members are arranged opposite to each other defining a gap which is configured for accommodating a guide member extending in a longitudinal direction. At least one of the engagement members is movable in a direction which is inclined with respect to the longitudinal direction. The first engagement member is pivotably coupled to the connector by means of a first joint, and the second engagement member is pivotably coupled to the connector by means of a second joint. At least one of the joints is movable along the connector for changing the distance between the first and second joints.
