Device for aligning an elevator guide rail

Abstract

Device for aligning an elevator guide rail, characterized in that the device comprises: a first section (100) for mounting on a support frame (800) which supports a guide rail element (700) of the elevator guide rail on a wall structure (900) of an elevator shaft, wherein the first section (100) extends in a first longitudinal direction (X); a second section (200) for mounting on the guide rail element (700); an articulated arm mechanism (300) which connects the first and the second section (100, 200); and a support frame fastening element (400, 500) for mounting the first section (100) on the support frame (800), wherein the support frame fastening element (400, 500) comprises: a sliding guide (410) attached to the first section (100) and extending in the first longitudinal direction (X);and a first sliding positioning arrangement (420, 520) and a second sliding positioning arrangement (430, 530), wherein the first sliding positioning arrangement (420, 520) and the second sliding positioning arrangement (430, 530) are configured to interact with the support frame (800) and are attached to the sliding guide (410) such that at least the first sliding positioning arrangement (420, 520) is displaceable relative to the sliding guide (410) in the first longitudinal direction (X).
