Abstract
Abstract A support apparatus for removing lugs from a vehicle wheel comprises a U shaped base member having a central rod rotatably coupled between the upstanding arms of the U via coaxial apertures in each arm. A T shaped section is located between the upstanding arms and is rigidly secured to the rod. A large lever arm is selectively inserted into the T shaped section to enable a user to develop a large torque while resting his foot and hence, applying his full body weight to the base of the U shaped member which is resting upon the ground when a force is exerted upon the upstanding lever arm. Once the lug is turned, the lever arm may be removed and the user has access to the rotatable rod to further rotate the lug so that it may be completely removed from the wheel.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
150 words
Apparatus for loosening and removing vehicle wheel lugs, comprising: (a) a "U" shaped base member having a first aperture located on a first upstanding arm of said "U" and a second coaxial aperture located on said second upstanding arm of said "U", (b) a central rod member rotatably positioned within said apertures, said rod extending from one side of said "U" and terminating in a socket member adapted to coact with said wheel lug, (c) a lever arm coupled to said rod between said upstanding arms and adapted when pivoted to rotate said rod to impart a large torque to said socket member with said base of said "U" shaped member positioned at an angle on the ground to provide a support for the foot of a user when pivoting said lever arm to enable said user to apply his body weight to said base when accessing said lever arm.
Claim 2
Dependent Claim
150 words
Apparatus for loosening and removing vehicle wheel lugs, comprising: (a) a "U" shaped base member having a first aperture located on a first upstanding arm of said "U" and a second coaxial aperture located on said second upstanding arm of said "U", (b) a central rod member rotatably positioned within said apertures, said rod extending from one side of said "U" and terminating in a socket member adapted to coact with said wheel lug, (c) a lever arm coupled to said rod between said upstanding arms and adapted when pivoted to rotate said rod to impart a large torque to said socket member with said base of said "U" shaped member positioned at an angle on the ground to provide a support for the foot of a user when pivoting said lever arm to enable said user to apply his body weight to said base when accessing said lever arm.
Claim 3
Dependent Claim
34 words
The apparatus according to claim 1 further including a T connecting member rigidly secured to said central rod between said arms and having a projecting tubular section for selectively inserting therein said lever arm.
Claim 4
Dependent Claim
34 words
The apparatus according to claim 2 wherein said lever arm, when removed from said tubular member enables said user to rotate said rod via said tubular member to remove said lug from said wheel.
Claim 5
Dependent Claim
33 words
The apparatus according to claim 1 wherein said other end of said rod is terminated in a ratchet socket adapted to receive a ratchet wrench for removing said lug by a ratchet action.
Claim 6
Dependent Claim
41 words
The apparatus according to claim 1 wherein said central rod includes gripping means on said rod as located between said upstanding arms to enable rotation of said rod when said base of said "U" shaped member is positioned on the ground.
Claim 7
Dependent Claim
21 words
The apparatus according to claim 2 wherein said tubular projection of said "T" connecting member is surrounded by an elastomeric material.
Claim 8
Dependent Claim
16 words
The apparatus according to claim 1 wherein said "U" shaped base member is fabricated from steel.
Claim 9
Dependent Claim
37 words
The apparatus according to claim 1 wherein a portion of said central rod is surrounded by a tubular pipe rigidly secured to at least one of said arms for rotatably containing a portion of said central rod.
Claim 10
Dependent Claim
37 words
The apparatus according to claim 1 wherein said "U" shaped member is dimensioned so that it assumes a given angle when said base is positioned on the ground with said socket member coacting with a wheel lug.
Claim 11
Dependent Claim
24 words
The apparatus according to claim 1 wherein said socket member is a hex socket member adapted to coact with a conventional automobile wheel lug.
