Abstract

A mobile floor light comprising a vertical mast having an upper end and a lower end with a cylindrical surface therebetween; a base secured to the lower end of the mast; a plurality of casters symmetrically secured to the base and adapted to rest on a recipient surface such as a floor; a rigid linear boom with an interior end and an exterior end; first adjustable securement components at the interior end of the boom and the upper end of the mast including a first locking lever movable between a first position wherein the boom angle may be varied with respect to the mast and a second position wherein the boom angle may be fixed with respect to the mast; a light head with a bulb; and second adjustable securement components at the exterior end of the boom and the light head including a second locking lever movable between a first position wherein the light head angle may be varied with respect to the boom and a second position wherein the light head angle may be fixed with respect to the mast.

Claims

1. A new and improved mobile floor light comprising, in combination:

a vertical mast having an upper end and a lower end with a cylindrical surface therebetween and a central axis therebetween;

a base with a circular periphery secured to the lower end of the mast;

three casters symmetrically secured to the base and adapted to rest on a recipient surface, the casters adding mobility to the base and mast and components secured thereto;

a rigid linear boom with an interior end and an exterior end;

first adjustable securement components at the interior end of the boom and the upper end of the mast including a first machine screw, thrust washers and a locking lever movable between a first position wherein the boom and mast form an angle which may be varied and a second position wherein the angle between the boom and mast may be fixed;

a light head with a bulb;

second adjustable securement components at the exterior end of the boom and the light head including a second machine screw, thrust washers and a locking lever movable between a first position wherein the light head angle may be varied with respect to the boom and a second position wherein the light head angle may be fixed with respect to the mast;

an electrical cord coupling the bulb to a source of potential;

cord winder brackets secured to the mast for receiving the cord; and

a neoprene bumper on the mast remote from the cord winders.

2. A mobile floor light comprising:

a vertical mast having an upper end and a lower end with a cylindrical surface therebetween;

a base secured to the lower end of the mast;

a plurality of casters symmetrically secured to the base and adapted to rest on a recipient surface;

a rigid linear boom with an interior end located over the base and an exterior end laterally offset from the base in cantilever fashion;

a pivot adjacent to the interior end of the boom and the upper end of the mast with first adjustable securement components thereat including a first locking lever movable between a first position wherein the boom may be varied with respect to the mast and a second position wherein the boom may be fixed with respect to the mast;

a light head with a bulb;

second adjustable securement components at the exterior end of the boom and the light head including a second locking lever movable between a first position wherein the light head angle may be varied with respect to the boom and a second position wherein the light head angle may be fixed with respect to the mast; and

a neoprene bumper on the mast on the side thereof remote from the cord winders.

3. The apparatus as set forth in claim 2 and further including an electrical cord operatively coupling the bulb to a source of potential.

4. The apparatus as set forth in claim 2 and further including cord winder brackets secured to the mast for receiving the cord.

5. The apparatus as set forth in claim 2 wherein the adjustable securement components include a machine screw coupled to a lever for rotation therewith and a nut threadably coupled thereto but fixedly positioned against rotation and with means therebetween to be tightened for position securement and to be loosened for position adjustment.
