Claim:
1. A mechanism for securing a handrail to an 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 a side of said wall facing said distal end wherein a transition of the first configuration to the second configuration of the metal shaft is enabled through the use of a pivoting member attached to and located towards the distal end of the metal shaft; 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 a width between 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 an outer surface of said receiver and into said bore, wherein said set screw has a diameter which is less than a width of said recessed channel at its greatest width but greater than a width of said recessed channel at its smallest width.
