Abstract
Abstract A one-piece resilient fitting of a tubular configuration for connecting a lever arm in axial alignment with a sleeve. The fitting is particularly adapted to isolate vibrations in the sleeve from the lever arm, and vice versa. Further, the fitting is adapted to transmit a positive force from the lever arm relative to the sleeve in the transverse direction, but is only adapted to resist, i.e., not transmit, axial motion of the lever arm relative to the sleeve. In assembly, the tubular fitting is designed to be snap-fit in nested relation within the sleeve, and then to permit the lever arm to be snap-fit in nested relation within the tubular fitting.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
223 words
A one-piece resilient fitting for connecting a lever arm in axial alignment with a sleeve, the outer periphEry of said lever arm being substantially less than the inner periphery of said sleeve so that a major gap of annular configuration is formed therebetween when said lever arm is telescoped into and positioned in axial alignment with said sleeve, said fitting including walls formed in a tubular configuration, the thickness of said walls being substantially less than the width of said major gap created between said lever arm''s outer periphery and said sleeve''s inner periphery, at least one boss molded integral with the outer faces of said tubular configuration, said boss being adapted to cooperate with a seat in the inner faces of said sleeve to maintain said fitting in axial alignment relative to said sleeve, at least one nipple molded integral with the inner faces of said sleeve, said nipple being adapted to cooperate with a cavity in said lever arm to maintain said lever arm in axial alignment with said fitting, and a series of ribs molded integral with at least one of the outer faces and the inner faces of said fitting, the depth of each of said ribs being at least about equal to the width of that minor gap created when said fitting, sleeve, and lever arm are assembled.
Claim 2
Dependent Claim
223 words
A one-piece resilient fitting for connecting a lever arm in axial alignment with a sleeve, the outer periphEry of said lever arm being substantially less than the inner periphery of said sleeve so that a major gap of annular configuration is formed therebetween when said lever arm is telescoped into and positioned in axial alignment with said sleeve, said fitting including walls formed in a tubular configuration, the thickness of said walls being substantially less than the width of said major gap created between said lever arm''s outer periphery and said sleeve''s inner periphery, at least one boss molded integral with the outer faces of said tubular configuration, said boss being adapted to cooperate with a seat in the inner faces of said sleeve to maintain said fitting in axial alignment relative to said sleeve, at least one nipple molded integral with the inner faces of said sleeve, said nipple being adapted to cooperate with a cavity in said lever arm to maintain said lever arm in axial alignment with said fitting, and a series of ribs molded integral with at least one of the outer faces and the inner faces of said fitting, the depth of each of said ribs being at least about equal to the width of that minor gap created when said fitting, sleeve, and lever arm are assembled.
Claim 3
Dependent Claim
54 words
A one-piece resilient fitting as set forth in claim 1 wherein the inner periphery of said sleeve is of substantially the same cross-sectional configuration as the outer periphery of said fitting, and wherein the inner periphery of said fitting is of substantially the same cross-sectional configuration as the outer periphery of said lever arm.
Claim 4
Dependent Claim
36 words
A one-piece resilient fitting as set forth in claim 1 wherein the depth of each of said ribs is slightly greater than the width of said minor gap when said fitting is in an unassembled attitude.
Claim 5
Dependent Claim
36 words
A one-piece resilient fitting as set forth in claim 1 wherein said ribs are aligned parallel to the axis of said fitting, and wherein said ribs are molded integral with the inner faces of said fitting.
Claim 6
Dependent Claim
33 words
A one-piece resilient fitting as set forth in claim 4 wherein said bosses and said nipples are positioned in substantially the same plane, said plane being transverse to the axis of said fitting.
Claim 7
Dependent Claim
36 words
A one-piece resilient fitting as set forth in claim 5 wherein said bosses and nipples are positioned on substantially the same centerline and molded integral with the walls of said fitting opposite one to the other.
Claim 8
Dependent Claim
16 words
A one-piece resilient fitting as set forth in claim 1 that is injection molded of polyurethane.
