Abstract
Abstract The clamp/door stop device comprises an elongate frame including an elongate base with first and second feet each mounted at one end of the base. The feet rest on a planar supporting surface such as a floor. The platform on the base has a planar rest, and a frame portion extends upwardly from the platform and has a planar surface generally perpendicular to the plane of the planar rest. A clamping mechanism for clamping a portion of a door or like object against the planar surface with the object abutting the planar rest are provided. A rod is mounted on the base for sliding movement relative to and transversely of the base in a direction generally parallel to the planar surface and generally 90° to an elongate axis of the elongate frame. A third foot is provided at one end of the rod and is movable with the rod between an extended position and a retracted position. A biasing spring is mounted on the rod at one end of the rod. A latch mechanism for latching the rod in a biased condition where the third foot is located in a retracted position is mounted at the other end of said rod.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
187 words
A clamp/door stop device comprising: an elongate frame including an elongate base portion with first and second feet each mounted at one end of said base portion and capable of resting on a planar surface such as a floor; a platform on said base having a planar rest; a frame portion extending upwardly from said platform and having a planar surface generally perpendicular to the plane of said planar rest; clamping means for clamping a portion of a door or like object against said planar surface with said object abutting said planar rest; a rod mounted on said base portion for sliding movement relative to and transversely of said base portion in a direction generally parallel to said planar surface and generally 90° to an elongate axis of said elongate frame; a third foot located at one end of said rod and movable with said rod between an extended position and a retracted position; means for biasing said one end of said rod away from said frame; and means for latching said rod in a biased condition where said third foot is located in said retracted position.
Claim 2
Dependent Claim
187 words
A clamp/door stop device comprising: an elongate frame including an elongate base portion with first and second feet each mounted at one end of said base portion and capable of resting on a planar surface such as a floor; a platform on said base having a planar rest; a frame portion extending upwardly from said platform and having a planar surface generally perpendicular to the plane of said planar rest; clamping means for clamping a portion of a door or like object against said planar surface with said object abutting said planar rest; a rod mounted on said base portion for sliding movement relative to and transversely of said base portion in a direction generally parallel to said planar surface and generally 90° to an elongate axis of said elongate frame; a third foot located at one end of said rod and movable with said rod between an extended position and a retracted position; means for biasing said one end of said rod away from said frame; and means for latching said rod in a biased condition where said third foot is located in said retracted position.
Claim 3
Dependent Claim
36 words
The device of claim 1 wherein said clamping means comprise a stationary jaw formation extending upwardly from one end of the base and a movable jaw formation extending upwardly from the other end of the base.
Claim 4
Dependent Claim
12 words
The device of claim 2 wherein said jaw formations have cushioned surfaces.
Claim 5
Dependent Claim
54 words
The device of claim 2 wherein said movable jaw formation comprises an operating screw received within a screw threaded bore in a boss of an upwardly extending arm of said device and has a ball joint head with a cushioned outer surface at one end thereof and a handle at the other end thereof.
Claim 6
Dependent Claim
23 words
The device of claim 1 wherein said rest is an anvil shaped rest disposed transversely of said platform and is slightly elevated therefrom.
Claim 7
Dependent Claim
18 words
The device of claim 1 wherein said rod is slidably mounted within a cylindrical boss of said device.
Claim 8
Dependent Claim
37 words
The device of claim 6 wherein said biasing means for said rod comprise a spring positioned around said rod between said third foot at the lower end of said rod and a lower end of the boss.
Claim 9
Dependent Claim
23 words
The device of claim 6 wherein an upper end of said rod extends from an upper end of said boss and is bifurcated.
Claim 10
Dependent Claim
23 words
The device of claim 8 including an eccentric over center cam received within the bifurcated portion of the rod and rotatably fixed therein.
Claim 11
Dependent Claim
30 words
The device of claim 9 wherein the eccentric over center cam is provided with a cam lever arm which is adapted to rotate the cam approximately 180° within the bifurcation.
Claim 12
Dependent Claim
47 words
The device of claim 10 wherein said cam acts through said rod and boss to apply tension to the biasing spring when it is rotated to a position where the greater area of the cam is within the bifurcation of the rod and bears against said boss.
Claim 13
Dependent Claim
19 words
The device of claim 10 wherein said cam and cam lever arm latch said spring in a biased condition.
Claim 14
Dependent Claim
30 words
The device of claim 1 wherein said first and second feet are pointed or knife edged to provide a fulcrum about which said device can rotate on a planar surface.
