Abstract

Abstract A vibration damper includes a hollow cylindrical member which is formed of an elastic material and to one end of which a fixture is secured a plug-like member which is formed of an elastic material, which has a flanged head portion with another fixture secured thereto, a neck portion to be inserted into the cylindrical member and which is disposed away from the cylindrical member in the axial direction such as to form spaces and an elastic connecting member for integrally connecting the cylindrical member and the plug-like member.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 181 words
A vibration damper comprising: a hollow cylindrical member which is formed of an elastic material and to a bottom end of which an outwardly facing fixture is secured, said cylindrical member defining a bore with a radial bore wall therein, said fixture being essentially coaxial with said bore; a plug member which is formed of an elastic material which has an integral, radially extended flanged head portion with another outwardly facing fixture secured thereto, said flanged head portion having a diameter larger than the inside diameter of said cylindrical member and said plug member having an integral neck portion within said bore of said cylindrical member, space being defined between said neck portion and a bottom end of said bore of said cylindrical member, the flanged head portion being disposed away from said cylindrical member in the axial direction such as to form spaces therebetween; and an elastic connecting member for integrally connecting said cylindrical member and said plug member said elastic member defining a plurality of spaces between said plug member and said bore wall of said hollow cylindrical member.
Claim 2
Dependent Claim 181 words
A vibration damper comprising: a hollow cylindrical member which is formed of an elastic material and to a bottom end of which an outwardly facing fixture is secured, said cylindrical member defining a bore with a radial bore wall therein, said fixture being essentially coaxial with said bore; a plug member which is formed of an elastic material which has an integral, radially extended flanged head portion with another outwardly facing fixture secured thereto, said flanged head portion having a diameter larger than the inside diameter of said cylindrical member and said plug member having an integral neck portion within said bore of said cylindrical member, space being defined between said neck portion and a bottom end of said bore of said cylindrical member, the flanged head portion being disposed away from said cylindrical member in the axial direction such as to form spaces therebetween; and an elastic connecting member for integrally connecting said cylindrical member and said plug member said elastic member defining a plurality of spaces between said plug member and said bore wall of said hollow cylindrical member.
Claim 3
Dependent Claim 29 words
The vibration damper of claim 1, said plurality of spaces between said plug member and said bore wall being circumferentially arranged about said plug member at essentially equal intervals.
Claim 4
Dependent Claim 19 words
The vibration damper of claim 2, including four of said spaces between said plug member and said bore wall.
Claim 5
Dependent Claim 24 words
The vibration damper of claim 3, wherein there are no more than four of said spaces between said plug member and said bore wall.
