Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
155 words
An extensible safety light for attachment to vehicle bodies and the like, to warn on coming traffic of impending danger, and including; a base-housing having a top and a bottom and with a chamber herein, there being means at said bottom for attachment to the vehicle body, a light source to be extended from the top of the base-housing, a collapsible tubular support means for the light source and opening from the chamber of the base housing and to the light source, and a conductor storage and supply means within the chamber and with at least one conductor and comprised of a flat convolute coil of a spring material with whorls thereof separated to avoid interference therebetween and emanating from the chamber and top of the base-housing and through the collapsible support means to the light source, there being energizing circuit means connected to the conductor storage and supply means to energize the light source.
Claim 2
Dependent Claim
155 words
An extensible safety light for attachment to vehicle bodies and the like, to warn on coming traffic of impending danger, and including; a base-housing having a top and a bottom and with a chamber herein, there being means at said bottom for attachment to the vehicle body, a light source to be extended from the top of the base-housing, a collapsible tubular support means for the light source and opening from the chamber of the base housing and to the light source, and a conductor storage and supply means within the chamber and with at least one conductor and comprised of a flat convolute coil of a spring material with whorls thereof separated to avoid interference therebetween and emanating from the chamber and top of the base-housing and through the collapsible support means to the light source, there being energizing circuit means connected to the conductor storage and supply means to energize the light source.
Claim 3
Dependent Claim
23 words
The extensible safety light as set forth in claim 1, wherein an inner of the convolute coil is anchored to the light source.
Claim 4
Dependent Claim
26 words
The extensible safety light as set forth in claim 1, wherein an outer whorl of the convolute coil is anchored within the chamber of the base-housing.
Claim 5
Dependent Claim
26 words
The extensible safet light as set forth in claim 1, wherein the convolute coil of the conductor storage and supply means is comprised of spring material.
Claim 6
Dependent Claim
57 words
The extensible safety light as set forth in claim 1, wherein the light source has multi-contacts, and wherein the conductor storage and supply means includes a multiplicity of said at least one conductor secured together one above the other in flat convolute formation to form said coil thereof and connected to said contacts of the light source.
Claim 7
Dependent Claim
147 words
The extensible safety light as set forth in claim 1, wherein the collapsible tubular support means is a telescoping support of slidable tubular members opening from the base-housing chamber and into the light source and passing the at least one conductor of the conductor storage and supply means, and wherein the light source has multi contacts and the conductor storage and supply means is comprised of a flat convolute coil of spring material comprising the at least one conductor with whorls thereof separated to avoid interference therebetween and includes a multiplicity of said at least one conductor secured together one above the other in said flat formation to form said coil thereof and with an outer whorl thereof anchored within the chamber of the base-housing and an inner whorl thereof tured upwardly and through the tubular support means and connected to said contacts of the light source.
