ELEVATOR HANDRAIL ATTACHMENT MECHANISM

摘要

The present invention relates to a mechanism and method for rigidly mounting a handrail to the interior of an elevator cab. The mechanism includes a threaded rod having a pivoting member at one end for passing through an existing or new opening in an elevator cab wall. Upon passing through the wall, the pivoting member can rotate to provide a brace against the exterior of the elevator cab wall. A base portion having a number of grooves on its exterior surface and threads on its interior surface threads onto the rod to create a solid connection to the cab's wall. The handrail, having a base portion receiver, is then securely attached to the cab by sliding over it the sleeve and having set screw(s) inserted through the handrail's receiver at points adjacent to the corresponding grooves in the sleeve.

主权项

1. A mechanism for securing a handrail to the interior of an elevator cab, the mechanism comprising:
a metal shaft having a male threaded portion extending from its proximal end toward its distal end wherein in a first configuration the distal end of the metal shaft is configured to be extended through an opening of a wall and in a second configuration is configured such that the metal shaft cannot be retracted through said opening by means of bracing against the side of said wall facing said distal end; a metal base portion having a central bore, at least a portion of said bore defining a female threaded surface for engaging the male threaded portion of said shaft, and an exterior surface having a recessed channel therein, wherein the width between the shoulders of said recessed channel decreases when viewed in a direction towards said central bore; and an elevator handrail having a plurality of receivers secured thereto, at least one of said receivers having a bore suitable for securely accepting said metal base portion; said receiver also including a set screw passing from the outer surface of said receiver and into said bore, wherein said set screw has a diameter which is less than the width of said recessed channel at its greatest width but greater than the width of said recessed channel at its smallest width.
