Abstract

A guide rail clamping assembly for elevator guide rails in which an intermediate mounting member having tapped openings and bolts attach rail clips to the guide rails, while thereafter permitting this whole assembly to be positionally adjusted as a unit. The bolts extend through openings in still another mounting member, and nuts engage the bolts to fix the unit to the associated building once it is correctly positioned. Each rail clip has first and second ends, with the first end being adapted to overlap a flange of the guide rail. An elongated opening extends between the ends of each rail clip, and the second end defines a notch. The intermediate mounting member has first and second ends, each of which defines a projection which is adapted to successively cooperate with an elongated slot during assembly of the guide rail, and with the notch during the clamping of the rail clip to the guide rail flange.

In a guide rail clamping assembly for fixing rail clips to an elevator guide rail while facilitating both fore-aft and between guide (B.G.) adjustment of the guide rail relative to a support structure, including a first mounting member adapted to be fastened to the support structure and which defines an elongated opening, a second mounting member adjacent to the first mounting member having first and second tapped openings aligned with the elongated opening of the first mounting member, first and second rail clip members for engaging the flanges of a guide rail, with each rail clip member having first and second ends, and an opening intermediate its ends aligned with a tapped opening of the second mounting member, first and second bolts extending through the openings in the first and second rail clip members, respectively, and engaging the first and second tapped openings, respectively, in the second mounting member, to enable the flanges of the guide rail to be tightly clamped and locked by the first ends of the rail clips against the second mounting member, with the first and second bolts further extending through the elongated opening in the first mounting member, permitting fore-aft and B.G. adjustment of the guide rail section relative to the first mounting member without releasing said lock, and first and second nuts on the first and second bolts, respectively, for clamping the rail clip members, second mounting member and associated guide rail to the first mounting member, the improvement comprising:

said opening in each of the first and second rail clip members being elongated in a direction between its ends to enable lateral movement of each rail clip relative to its associated bolt for receiving a guide rail, and including a notch in the second end of each rail clip,
and first and second projections on the second mounting member, said first and second projections being adapted to extend into the elongated openings of the first and second rail clips, respectively, to orient, laterally guide and prevent rotation of the associated rail clip while it is being moved to receive a guide rail, said first and second projections extending into the notches at the second ends of the first and second rail clips, respectively, to orient and prevent rotation and retraction of the rail clips when they are in their clamping position relative to a guide rail.
