Abstract
Abstract Disclosed is a stanchion support device which comprises a washer having secured thereto a threaded column. About the threaded column is a toroidal collar of hard rubber. Placed over the threaded column is a metal sleeve. Threaded onto the threaded column is a nut which forces the metal sleeve downward against the rubber collar and pulls upwardly on the washer. The combined force of the sleeve and washer causes the rubber to expand. When this combination is placed within a cavity, such as may be defined by a cup placed in a cement floor, the rubber is so dimensioned as to engage the cup wall, thereby securing the stanchion support device within the cup. A stanchion may be secured to the nut. The stanchion itself may be provided with one or more L-shaped brackets which are freely rotatable thereupon and retained from sliding down the stanchion by a support, such as a ring, welded to the stanchion. An enlarged head of the stanchion prevents the removal of the bracket off the top of the stanchion.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
110 words
Means for securing a stanchion, wherein the stanchion being of the type which may be secured or released by rotation with respect to a work surface, said securing means comprising: a. stanchion means; and b. member means secured to said stanchion and movable with respect thereto such that with said member means being in a first position with respect to said stanchion, said member means being substantially rotable with respect to said stanchion means; with said member means being in a second position with respect to said stanchion, said member means upon rotation with respect to said stanchion engaging a predetermined part of said stanchion to thereby turn said stanchion.
Claim 2
Dependent Claim
110 words
Means for securing a stanchion, wherein the stanchion being of the type which may be secured or released by rotation with respect to a work surface, said securing means comprising: a. stanchion means; and b. member means secured to said stanchion and movable with respect thereto such that with said member means being in a first position with respect to said stanchion, said member means being substantially rotable with respect to said stanchion means; with said member means being in a second position with respect to said stanchion, said member means upon rotation with respect to said stanchion engaging a predetermined part of said stanchion to thereby turn said stanchion.
Claim 3
Dependent Claim
49 words
Means for securing a stanchion as recited in claim 1 wherein said member means comprises bracket means and wherein said engaging means comprises said bracket means having an aperture therethrough the size of which being so dimensioned as to grasp, upon being rotated, said predetermined portion of said stanchion.
Claim 4
Dependent Claim
37 words
Means for securing a stanchion as recited in claim 2 wherein said first and second positions being relative to the principal axis of said stanchion and said rotation being substantially perpendicular to the axis of said stanchion.
Claim 5
Dependent Claim
33 words
Means for securing a stanchion as recited in claim 3 wherein said bracket means comprises a member so dimensioned as to be capable of receiving therein guard-rail members while in said first position.
Claim 6
Dependent Claim
120 words
Means for securing a stanchion as recited in claim 4 wherein said stanchion being substantially cylindrical and having a portion thereof forming a substantially elliptical cross-section with respect to the remainder thereof, said bracket means being L-shaped and having said aperture in one leg thereof, said aperture being substantially elliptical in shape such that when placed on said cylindrical portion of said stanchion, said bracket being freely rotatable and when placed at said elliptical portion of said stanchion being capable, upon rotation, of engaging said elliptical portion of said stanchion, said stanchion further comprises stop means at the top end thereof extending substantially radially beyond said diameter of said stanchion thereby preventing the removal of said bracket from said stanchion.
