Abstract
Abstract A shock isolating lamp assembly for a vehicle lamp including an improved shock isolating mounting is provided. The assembly includes a lamp housing for receiving a lens and a shock isolating mount of a resilient material including a central body portion formed with a vertical opening for receiving a lamp socket and two opposed pairs of parallel arms symmetrical to the center line extending outwardly from the body in a plane. The arms are spaced apart a distance approximately the diameter of the lamp socket. Each pair of arms is joined to a perpendicular mounting bar of the same resilient material which cooperates with a pair of opposed mounting tracks extending into the lamp housing. The lamp socket is substantially tubular, open at the top and bottom end and formed with a pair of opposed barbs for engagement by a pair of opposed recesses formed in the inner wall of the mount body portion for retaining the socket therein.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
132 words
A shock isolating vehicle lamp assembly comprising: a lamp housing defining a lamp cavity and a lens forming a surface of said assembly; a pair of opposed substantially parallel mounting tracks spaced apart from each other and disposed in said lamp housing within said cavity; and a resilient shock isolating moldment adapted to be mounted on and between said mounting tracks, said moldment including a central body portion formed with a substantially cylindrical opening therein having a central axis for retaining a metal lamp socket, said moldment further including a pair of opposed arm means extending outwardly in a plane perpendicular to said central axis of said moldment, each said arm means joined to a transverse mounting bar, said mounting bars adapted to be engaged by said opposed pair of mounting tracks.
Claim 2
Dependent Claim
132 words
A shock isolating vehicle lamp assembly comprising: a lamp housing defining a lamp cavity and a lens forming a surface of said assembly; a pair of opposed substantially parallel mounting tracks spaced apart from each other and disposed in said lamp housing within said cavity; and a resilient shock isolating moldment adapted to be mounted on and between said mounting tracks, said moldment including a central body portion formed with a substantially cylindrical opening therein having a central axis for retaining a metal lamp socket, said moldment further including a pair of opposed arm means extending outwardly in a plane perpendicular to said central axis of said moldment, each said arm means joined to a transverse mounting bar, said mounting bars adapted to be engaged by said opposed pair of mounting tracks.
Claim 3
Dependent Claim
26 words
The assembly of claim 1, wherein each said arm means is a pair of substantially parallel elongated spaced arms joined to one of said mounting bars.
Claim 4
Dependent Claim
51 words
The assembly of claim 2, wherein each pair of opposed arms is symmetrically positioned with respect to said cylindrical opening wherein said assembly includes a lamp socket in said cylindrical opening and wherein each pair of arms is spaced apart a distance substantially equal to the diameter of said lamp socket.
Claim 5
Dependent Claim
73 words
The assembly of claim 3, wherein said arms are substantially cylindrical and the width of each mounting bar at its connection to the cylindrical arms is greater than the diameter of each said arms, and each mounting track for receiving said mounting bar is constructed and arranged to avoid contact with said arms so as to avoid interference with said arms during deflection thereof as a result of shocks applied to said assembly.
Claim 6
Dependent Claim
73 words
The assembly of claim 4, wherein said body portion of said moldment is formed with an upper portion and a lower portion with parts of the upper portion overhanging said lower portion, and an opening formed in said overhanging region of said upper portion for compressively receiving an electrical lead which supplies current to a lamp mounted in said lamp socket for relieving strain on an electrically connected end of an electrical lead.
Claim 7
Dependent Claim
34 words
The assembly of claim 5, wherein said central body portion of said moldment is formed with a bottom wall having at least one opening therethrough for receiving an electrical contact for contacting said lamp.
Claim 8
Dependent Claim
35 words
The assembly of claim 3, including a substantially tubular metal lamp socket open at the top and bottom thereof for receiving a lamp, said socket compressively retained in the cylindrical opening of said moldment body.
Claim 9
Dependent Claim
45 words
The assembly of claim 7, wherein said tubular metal lamp socket is formed with a pair of opposed barbs extending outwardly and said cylindrical opening is formed with a pair of opposed recesses cooperating with said barbs for retaining said lamp socket in said opening.
Claim 10
Dependent Claim
28 words
The assembly of claim 1, wherein said moldment is formed from a silicon rubber having a natural frequency substantially less than the natural frequency of a lamp filament.
Claim 11
Dependent Claim
156 words
A shock isolating vehicle lamp assembly comprising: a lamp housing defining a lamp cavity and a lens forming a front surface of said assembly; a pair of opposed substantially parallel mounting tracks spaced apart from each other and disposed in said lamp housing within said cavity from the front to the rear of said housing; a resilient shock isolating moldment adapted to be mounted on and between said mounting tracks, said moldment including a central body portion formed with a substantially cylindrical opening having a central axis for retaining a metal lamp socket, said moldment further including two pair of opposed substantially cylindrical spaced apart parallel arms extending outwardly in a plane perpendicular to said central axis of said moldment, each pair of arms joined to a transverse mounting bar, said mounting bars adapted to be engaged by said opposed pair of mounting tracks; and a substantially cylindrical metal lamp socket compressively retained in said opening.
Claim 12
Dependent Claim
156 words
A shock isolating vehicle lamp assembly comprising: a lamp housing defining a lamp cavity and a lens forming a front surface of said assembly; a pair of opposed substantially parallel mounting tracks spaced apart from each other and disposed in said lamp housing within said cavity from the front to the rear of said housing; a resilient shock isolating moldment adapted to be mounted on and between said mounting tracks, said moldment including a central body portion formed with a substantially cylindrical opening having a central axis for retaining a metal lamp socket, said moldment further including two pair of opposed substantially cylindrical spaced apart parallel arms extending outwardly in a plane perpendicular to said central axis of said moldment, each pair of arms joined to a transverse mounting bar, said mounting bars adapted to be engaged by said opposed pair of mounting tracks; and a substantially cylindrical metal lamp socket compressively retained in said opening.
Claim 13
Dependent Claim
28 words
The assembly of claim 10, wherein said moldment is formed from a silicon rubber having a natural frequency substantially less than the natural frequency of a lamp filament.
