Abstract
Abstract This invention provides a rubberized stud (10), preferably the molded configuration has a ball shape with a rubber height (28) to thickness (29) ratio of 2.0 to 3.0 and preferably 2.2 to 2.7 which can be compressed sufficiently to be inserted into a smaller diameter shaped socket to maintain the rubber under compression of 20 to 30% of its thickness and thereby produce a spring effect when the ball rod is rotated or twisted.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
85 words
A rubberized stud member for a vehicle steering assembly including a metallic ball rod having a ball on one end thereof, said ball having a covering of rubber of 60 to 70 durometer hardness with a thickest section and thinnest sections, said thinnest sections of rubber being at least about 0.079 to 0.159 centimeters thick and the thickest section of rubber being a band at least about 0.44 to 0.70 centimeters thick, said band having a width to thickness ratio of about 2.0 to 3.0.
Claim 2
Dependent Claim
85 words
A rubberized stud member for a vehicle steering assembly including a metallic ball rod having a ball on one end thereof, said ball having a covering of rubber of 60 to 70 durometer hardness with a thickest section and thinnest sections, said thinnest sections of rubber being at least about 0.079 to 0.159 centimeters thick and the thickest section of rubber being a band at least about 0.44 to 0.70 centimeters thick, said band having a width to thickness ratio of about 2.0 to 3.0.
Claim 3
Dependent Claim
30 words
The rubberized ball stud of claim 1 wherein a thinnest section occurs adjacent a section of the ball that joins the rod and adjacent a lower section of said ball.
Claim 4
Dependent Claim
39 words
The rubberized ball stud of claim 1 wherein the band dimensions are sufficient that the original radius of said band is compressed 23 to 30% rubber thickness in the thickest section when in the assembled condition within its socket.
Claim 5
Dependent Claim
19 words
The rubberized ball stud of claim 1 wherein the rubber is a sulfur cured carbon black loaded natural rubber.
Claim 6
Dependent Claim
19 words
The rubberized ball stud of claim 2 wherein the rubber is a sulfur cured carbon black loaded natural rubber.
Claim 7
Dependent Claim
19 words
The rubberized ball stud of claim 3 wherein the rubber is a sulfur cured carbon black loaded natural rubber.
Claim 8
Dependent Claim
25 words
The rubberized ball stud of claim 2 wherein the surface curves gently upward from the thinnest section to meet the wall of the thickest section.
