Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
118 words
An elastic ball joint for steering rods of automotive vehicles, comprising a first rod including a socket housing portion, said first rod having a longitudinal axis, a second rod having a ball-head portion disposed in said socket housing, said socket housing and said ball-head cooperatively constituting a ball joint, two separate elastic means each having a different elasticity and disposed in said socket housing about said ball-head, said two elastic means each being disposed in a different position spaced along said longitudinal axis and on opposite sides of the longitudinal axis of said second rod, thereby providing different elasticities in a longitudinal and pulling and pushing, respectively, constituting a compression and tension, direction respectively, of said first rod.
Claim 2
Dependent Claim
118 words
An elastic ball joint for steering rods of automotive vehicles, comprising a first rod including a socket housing portion, said first rod having a longitudinal axis, a second rod having a ball-head portion disposed in said socket housing, said socket housing and said ball-head cooperatively constituting a ball joint, two separate elastic means each having a different elasticity and disposed in said socket housing about said ball-head, said two elastic means each being disposed in a different position spaced along said longitudinal axis and on opposite sides of the longitudinal axis of said second rod, thereby providing different elasticities in a longitudinal and pulling and pushing, respectively, constituting a compression and tension, direction respectively, of said first rod.
Claim 3
Dependent Claim
55 words
The elastic ball joint, as set forth in claim 1, wherein said two means constitute two bearing means surrounding said ball head and divided in a plane disposed crosswise to said longitudinal axis and axially with respect to said ball head to form two halves, and said two halves are of materials having different elasticities.
Claim 4
Dependent Claim
60 words
The elastic ball joint, as set forth in claim 1, wherein said two means constitute two bearing means surrounding said ball head and divided in a plane disposed crosswise to said longitudinal axis and axially with respect to said ball head to form two halves, and said two halves of said bearing means have different configurations providing said different elasticities.
Claim 5
Dependent Claim
56 words
The elastic ball joint, as set forth in claim 1, wherein said two means constitute two bearing means surrounding said ball head and divided in a plane disposed crosswise to said longitudinal axis and axially with respect to said ball head to form two halves, and said two halves of said bearing means have different wall-thicknesses.
