A portable emergency lighting system includes a base that has an upwardly directed socket with a post adapted to be received in the socket and an elongated bar having a second socket received on the upper end of the post and having one or more lights supported thereon. The first socket on the base has a pin extending across the opening and the post has a plurality of angularly related recesses respectively adapted to receive the pin while the opposite end has a like number of angularly related recesses which are angularly offset from the lower set and cooperate with a second pin in the second socket so that the light can be held in a plurality of distinct positions on the upper end of the post for each distinct position between the lower end of the post and the base.
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.
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.
An adjustable support for an elongated bar having a directed mechanism thereon comprising:

The present invention relates generally to lighting systems and, more specifically, to a portable lighting system used in areas where a permanent lighting system is impracticable.
Portable lighting systems have been in use for sometime, particularly in the fire fighting field. When fighting fires, it is many times necessary to have additional lighting than which is available, and usually such lighting requires a separate power source since commercial power is generally not readily available in areas of fires.
In such emergency conditions, it is usually necessary to be able to erect such a lighting system in a short period of time and also to provide directional capability that is easily adjustable so that the light can be directed to the desired location.
FIG. 1 shows the portable lighting system having a support constructed in accordance with the teachings of the present invention;
FIG. 2 is an exploded perspective view of the components illustrated in FIG. 1;
FIG. 3 is a cross-sectional view as viewed along line 3--3 of FIG. 1;
While this invention is susceptible of embodiment in many different forms, there is shown in the drawing and will herein be described in detail preferred embodiments of the invention with the understanding that the present disclosure to be considered as an exemplification of the principles of the invention and is not intended to limit the invention to the embodiments illustrated.
FIG. 1 of the drawings discloses a portable emergency lighting system, generally designated by reference numeral 10. The lighting system may be considered as including three major components, namely, a base 12, an elongated post or support 14, and a lighting assembly 16 at the opposite end of the post.
Base 12 is illustrated in detail in FIGS. 1 and 2 and includes a generally L-shaped bracket which has a vertical leg 20 defining a lug that is adapted to be received into a slot 22 that is normally found on the truck bed 24 of a conventional pick-up truck. Truck bed 24 may be considered part of the frame of the vehicle for descriptive purposes.
