Abstract
Abstract A removable arm rest apparatus for use in a truck cab utilizes an upright tubing structure and a flat arm support member projecting normally outward therefrom. Compressive mounting means enclosed within the uppermost end of the tubing structure position the tubing structure firmly between the cab roof and cab floor. A washer encircling the tubing structure positions the arm support member at the desired location. Movement of the washer along the longitudinal axis of the tubing structure adjusts the height of the arm support member relative to the cab floor. The apparatus may be easily removed and disassembled for storage and subsequent use in another truck cab.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
113 words
A removable arm support apparatus for use in a truck cab having a roof and an accessible floor, said apparatus comprising: (a) an upright tubular member; (b) means for resiliently mounting said tubular member between the roof and the floor of the cab; (c) means for achoring said tubular member on the floor of said cab; (d) a rubber washer encircling an outside surface of said tubular member, said washer being selectively positionable along a longitudinal axis thereof; (e) a flat arm rest member having an aperture proximal one end thereof for insertion of said tubular member, said arm rest member resting atop said washer and projecting normally outwardly from said tubular member.
Claim 2
Dependent Claim
113 words
A removable arm support apparatus for use in a truck cab having a roof and an accessible floor, said apparatus comprising: (a) an upright tubular member; (b) means for resiliently mounting said tubular member between the roof and the floor of the cab; (c) means for achoring said tubular member on the floor of said cab; (d) a rubber washer encircling an outside surface of said tubular member, said washer being selectively positionable along a longitudinal axis thereof; (e) a flat arm rest member having an aperture proximal one end thereof for insertion of said tubular member, said arm rest member resting atop said washer and projecting normally outwardly from said tubular member.
Claim 3
Dependent Claim
69 words
An apparatus as defined in claim 1 wherein said means for resiliently mounting comprises: (a) a support pin extending diametrically across said tubular member near an upper end thereof; (b) a telescoping rod projecting outwardly from the upper end of said tubular member; (c) a spring with a lower end abutting against said support pin and an upper end urging said telescoping rod upward into engagement with said roof.
Claim 4
Dependent Claim
37 words
An apparatus as defined in claim 2 wherein a rubber dust cap encloses the upper end of said tubular member, said dust cap having a small central aperture to allow extension of said telescoping rod member therethrough.
Claim 5
Dependent Claim
19 words
An apparatus as defined in claim 3 wherein said telescoping rod is slidably engaged within said small central aperture.
Claim 6
Dependent Claim
40 words
An apparatus as defined in claim 2 wherein a flat rubber stop on a lowermost end of said telescoping rod rests on said spring and a rubber cup-like member on an uppermost end of said telescoping rod engages said roof.
Claim 7
Dependent Claim
38 words
An apparatus as defined in claim 2 wherein said tubular member comprises a lower tube section which may be selectively disengaged from an upper tube section, said disengagement permitting more convenient removal of the apparatus from said cab.
Claim 8
Dependent Claim
25 words
An apparatus as defined in claim 1 wherein a rubber end stop encloses a lower end of said tubular member and rests on said floor.
Claim 9
Dependent Claim
33 words
An apparatus as defined in claim 7 wherein said means for anchoring comprises a mounting bracket affixed to the floor of said cab, the lower end of said tubular member being inserted therein.
Claim 10
Dependent Claim
37 words
An apparatus as defined in claim 1 wherein said arm rest member comprises: (a) an elongated plate-like member; (b) a padded covering for said said plate-like member, said covering providing a resting place for a driver's arm.
Claim 11
Dependent Claim
48 words
An apparatus as defined in claim 9 wherein said aperture is sufficiently limited in diameter such that said arm rest member rests atop said washer, a downward pressure of the driver's arm distal said aperture urging said arm rest member against said tubular member to prevent slippage therebetween.
Claim 12
Independent Claim
89 words
An apparatus for supporting a driver's right arm during operation of a motor vehicle, said apparatus comprising: (a) a vertically disposed tubular member placed in a cab of said vehicle; (b) means for resiliently mounting said tubular member between a floor and a roof of said cab; (c) a horizontally disposed elongated platform providing a resting place for said driver's arm, said platform having an aperture proximal one end thereof for insertion of said tubular member; (d) a rubber washer slidably engaging said tubular member beneath said elongated platform.
Claim 13
Independent Claim
89 words
An apparatus for supporting a driver's right arm during operation of a motor vehicle, said apparatus comprising: (a) a vertically disposed tubular member placed in a cab of said vehicle; (b) means for resiliently mounting said tubular member between a floor and a roof of said cab; (c) a horizontally disposed elongated platform providing a resting place for said driver's arm, said platform having an aperture proximal one end thereof for insertion of said tubular member; (d) a rubber washer slidably engaging said tubular member beneath said elongated platform.
Claim 14
Dependent Claim
41 words
An apparatus as defined in claim 11 wherein said tubular member is comprised of a tapered lower tube inserted within an upper tube, said lower tube being disengagable from said upper tube to facilitate removal of the apparatus from said cab.
Claim 15
Dependent Claim
98 words
An apparatus as defined in claim 12 wherein said means for resiliently mounting comprises: (a) a pin inserted in a lower end of said upper tube perpendicular to a longitudinal axis thereof; (b) a dust cover sealing an upper end of said upper tube, said cover having a central aperture therein; (c) a telescoping tube slidably engaged in said central aperture and extending outwardly therefrom into contact with said roof; (d) a spring inserted in said upper tube and having a lower end resting on said pin and an upper end exerting upward force on said telescoping tube.
Claim 16
Dependent Claim
43 words
An apparatus as defined in claim 13 wherein a flat rubber disc on a bottom end of said telescoping tube contacts the upper end of said spring and a concave rubber disc on a top end of said telescoping tube contacts said roof.
Claim 17
Dependent Claim
27 words
An apparatus as defined in claim 12 wherein said means for resiliently mounting further comprises a receptacle mounted on said floor, said lower tube being retained therein.
Claim 18
Dependent Claim
34 words
An apparatus as defined in claim 12 wherein said means for resiliently mounting further comprises a rubber foot on said lower tube, said foot resting on said floor and securing said lower tube thereto.
Claim 19
Dependent Claim
48 words
An apparatus as defined in claim 11 wherein an end of said platform opposite said aperture is padded to provide a comfortable resting place for the arm of said driver, a downward force exerted by said arm thereby mounting said platform between said washer and said tubular member.
