Abstract

Abstract A clamping arrangement for fastening a drop-in device in an opening in a work surface. A trim, formed integrally with the drop-in device, overlies and extends generally parallel to the work surface. A threaded stud is permanently attached to and extends downwardly from the trim. A clamp member has first and second right angularly disposed legs with a hole in the second leg. The threaded stud extends through the hole and a nut is threaded on the stud, the nut being movable between clamping and unclamping positions. In moving to its clamping position, the nut causes the upwardly extending first leg to engage the trim and the second leg to engage the work surface.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 247 words
A pull down clamping arrangement for fastening a drop-in device in an opening in a work surface, comprising: a. a trim formed integrally with said drop-in device and designed to overlie the work surface adjacent the opening therein; said trim extending generally parallel to the work surface; b. a plurality of threaded studs permanently attached to and extending downwardly from said trim; c. at least one clamp member having at least an upwardly extending first leg and a longitudinally extending second leg extending at right angles to each other; d. said longitudinally extending second leg having at least one hole located intermediate the two ends thereof; e. at least one of said threaded studs extending through said at least one hole in said longitudinally extending second leg of said at least one clamp member; f. at least one nut threaded on said at least one of said threaded studs, said at least one nut being movable between a clamping position and an unclamping position, said at least one nut in moving to its clamping position causing said upwardly extending first leg of said at least one clamp member to bear against said trim of said drop-in device and said longitudinally extending second leg of said at least one clamp member to bear against the work surface to draw said trim of said drop-in device down tightly against the work surface adjacent the opening in the work surface to securely fasten said drop-in device to the work surface.
Claim 2
Dependent Claim 247 words
A pull down clamping arrangement for fastening a drop-in device in an opening in a work surface, comprising: a. a trim formed integrally with said drop-in device and designed to overlie the work surface adjacent the opening therein; said trim extending generally parallel to the work surface; b. a plurality of threaded studs permanently attached to and extending downwardly from said trim; c. at least one clamp member having at least an upwardly extending first leg and a longitudinally extending second leg extending at right angles to each other; d. said longitudinally extending second leg having at least one hole located intermediate the two ends thereof; e. at least one of said threaded studs extending through said at least one hole in said longitudinally extending second leg of said at least one clamp member; f. at least one nut threaded on said at least one of said threaded studs, said at least one nut being movable between a clamping position and an unclamping position, said at least one nut in moving to its clamping position causing said upwardly extending first leg of said at least one clamp member to bear against said trim of said drop-in device and said longitudinally extending second leg of said at least one clamp member to bear against the work surface to draw said trim of said drop-in device down tightly against the work surface adjacent the opening in the work surface to securely fasten said drop-in device to the work surface.
Claim 3
Dependent Claim 55 words
A pull-down clamping means as set forth in claim 1 wherein: a. said clamp member in substantially Z-shaped in configuration; and b. said clamp member includes a third leg extending at right angles to said second leg of said clamp member and extending in an opposed direction to said first leg of said clamp member.
