Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
146 words
A lamp for use in a vehicle subjected to shock and vibration having a rigid reflector, a lens attached to the reflector and cooperative therewith to define a cavity, a flexible bulb support having a central bulb receiving portion, and a bulb in the central receiving portion, characterized by means for resiliently mounting the flexible support in said cavity in the lamp, wherein a reduced amount of vehicle shock and vibration received by the lamp is transmitted to the bulb support since the resilient mounting permits movement of the entire bulb support relative to the reflector whereby the resilient mounting absorbs some shock and vibration and a reduced amount of the shock and vibration received by the bulb support is transmitted to the bulb since flexure of the bulb support absorbs some of the shock and vibration transmitted from the resilient mounting to the bulb support.
Claim 2
Dependent Claim
146 words
A lamp for use in a vehicle subjected to shock and vibration having a rigid reflector, a lens attached to the reflector and cooperative therewith to define a cavity, a flexible bulb support having a central bulb receiving portion, and a bulb in the central receiving portion, characterized by means for resiliently mounting the flexible support in said cavity in the lamp, wherein a reduced amount of vehicle shock and vibration received by the lamp is transmitted to the bulb support since the resilient mounting permits movement of the entire bulb support relative to the reflector whereby the resilient mounting absorbs some shock and vibration and a reduced amount of the shock and vibration received by the bulb support is transmitted to the bulb since flexure of the bulb support absorbs some of the shock and vibration transmitted from the resilient mounting to the bulb support.
Claim 3
Dependent Claim
29 words
A lamp as recited in claim 1, wherein each end of said flexible bulb support is attached to a spherical element which is received in said resilient mounting means.
Claim 4
Dependent Claim
25 words
A lamp as recited in claim 2, wherein said flexible bulb support can freely pivot about a single horizontal axis in said resilient mounting means.
Claim 5
Dependent Claim
23 words
A lamp as recited in claim 2, including means for dampening vertical and horizontal movement of the bulb support relative to the reflector.
Claim 6
Dependent Claim
44 words
A lamp as recited in claim 4, wherein said dampening means includes a relatively rigid member attached to one of the bulb support or the reflector which cooperates with a second resilient member attached to the other of the bulb support or the reflector.
Claim 7
Dependent Claim
52 words
A lamp as recited in claim 5, wherein said rigid member and said second resilient member telescope and friction between the two members dampens vertical movement of said flexible bulb support, and said rigid member and said second resilient member cooperate to dampen movement of the bulb support in a horizontal plane.
