Abstract
A guide rail support of an elevator includes a guide rail bracket having a first side, a second side, a first mounting portion, and a second mounting portion. The first mounting portion is attachable to an elevator shaft and the guide rail bracket has inclined apertures in the second mounting portion. An adjustment bracket is configured to contact the second side at the second mounting portion, the adjustment bracket having inclined apertures configured to align with the inclined apertures of the guide rail bracket to define stem apertures. First and second rotating members are installed through the stem apertures. Each rotating member has (i) a rotating head that movably engages with a guide rail, (ii) an integrally formed stem configured to pass through a respective stem aperture, and (iii) a middle defining a length that is greater than a thickness of the guide rail bracket and the adjustment bracket.
