Portable lighting system

Claim 2

A portable lighting system comprising a bar having a plurality of directional floodlights thereon, a socket on said bar having an open end with pin means extending across said socket spaced from said open end, and a support including an elongated tubular member having a plurality of angularly related recesses respectively adapted to receive said pin means to support said bar in a plurality of angularly related positions on said support.

Claim 3

A portable lighting system as defined in claim 1, in which said support includes a base defining an upwardly directed socket having a second pin means extending across said socket, said tubular member having a plurality of angularly related second recesses respectively adapted to support said tubular member and bar at a plurality of angularly related positions with respect to said base.

Claim 4

A portable lighting system as defined in claim 2, in which base includes a lug adapted to be releasably retained in a slot defined in a vehicle frame.

Claim 5

A portable lighting system as defined in claim 2, in which there are at least four first recesses having substantially equal angular spacing on one end of said tubular member and at least four second recesses having substantially equal angular spacing on an opposite end with said first and second recesses angularly offset from each other to increase the number of angularly related positions for said bar with respect to said base.

Claim 6

A portable lighting system as defined in claim 2, in which said base includes a substantially C-shaped member having a base portion and a pair of legs extending from said base portion with a circular tube supported on said legs, said tube having a pin extending diametrically across an opening in the center thereof to define said second pin means.

Claim 7

A portable lighting system as defined in claim 2, further including means between said bar and each floodlight providing adjustment about two perpendicular axes.

Claim 8

A portable lighting system comprising a base having an upwardly open socket, an elongated post having opposite ends with one end received in said socket, first engaging means between said socket and said one end of said elongated post defining a plurality of distinct angular positions for said elongated post on said base, light means supported on the other end of said elongated post, and second engaging means between said elongated post and said second socket defining a plurality of distinct positions between said bar and said elongated post for each distinct position between said elongated post and said base.

Claim 9

A portable lighting system comprising a base having an upwardly open socket, an elongated post having opposite ends with one end received in said socket, first engaging means between said socket and said one end of said elongated post defining a plurality of distinct angular positions for said elongated post on said base, light means supported on the other end of said elongated post, and second engaging means between said elongated post and said second socket defining a plurality of distinct positions between said bar and said elongated post for each distinct position between said elongated post and said base.

Claim 10

A portable lighting system as defined in claim 7, in which said post has a set of angularly related recesses on each end of said posts and each socket has a pin adapted to be received into each recess on an associated end of said post.

Claim 11

A portable lighting system as defined in claim 8, in which there are at least four angularly related recesses in each set on each end of said elongated post and the sets of recesses on opposite ends of said elongated post are offset from each other.

Claim 12

An adjustable support for an elongated bar having a directed mechanism thereon comprising: a base having a socket defining an upwardly directed opening with a pin extending across said opening, a tubular member corresponding substantially in size to said opening and having one end adapted to be telescoped into said socket, said one end of said tubular member having engaging means with said pin defining a plurality of distinct angularly related positions between said socket and said tubular member, said elongated bar having a second downwardly directed socket having an opening and adapted to be telescoped over the other end of said tubular member and having a second pin extending across the opening therein, said other end of said tubular member having second engaging means with said second pin and defining a plurality of distinct angularly related positions between said bar and said tubular member so that said elongated bar can be adjusted to a plurality of distinct positions circumscribing an arc of 360° with respect to said base.

Claim 13

An adjustable support for an elongated bar having a directed mechanism thereon comprising: a base having a socket defining an upwardly directed opening with a pin extending across said opening, a tubular member corresponding substantially in size to said opening and having one end adapted to be telescoped into said socket, said one end of said tubular member having engaging means with said pin defining a plurality of distinct angularly related positions between said socket and said tubular member, said elongated bar having a second downwardly directed socket having an opening and adapted to be telescoped over the other end of said tubular member and having a second pin extending across the opening therein, said other end of said tubular member having second engaging means with said second pin and defining a plurality of distinct angularly related positions between said bar and said tubular member so that said elongated bar can be adjusted to a plurality of distinct positions circumscribing an arc of 360° with respect to said base.

Claim 14

An adjustable support mechanism as defined in claim 10, in which each end of said tubular member has a set of angularly related recesses defining said first and second engaging means and the sets of recesses are identical in number and are equally spaced from each other with the respective sets angularly offset.
