Abstract

Abstract A heavy castor mounted work stand cabinet forms the support base for a fixed vertical stanchion extending up a backside of the stand. The stanchion pivotally supports, at its top end, an elongated arm which extends outwardly above and past the front face of the work stand. Adjustable means are provided for supporting the arm either at right angles to the stanchion or at an obtuse angle with respect thereto. Pairs of parallel, spaced apart fluorescent light sources are positioned along forward and downwardly facing faces of the stanchion and of the arm, respectively, and the faces of the stanchion and the arm are each provided with surfaces of high light reflecting capability, said surfaces facing outwardly from each other at an obtuse angle. The weight and length of the arm and the weight of the stand are such that the device will not tip even when the stand is empty and the arm is in its horizontal position. Shelves in the cabinet are provided for the storage of work tools and supplies which, when so stored make the unit more stable and less susceptible to accidental tipping.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 115 words
A portable illumination source and stand therefor including a wheel mounted base constituted as a rectilinear box having a front face and an opposite rear wall; a vertical stanchion fixedly mounted with respect to said rear wall, said stanchion having a pair of adjacent, integrally connected forwardly and outwardly facing vertical reflector walls; a pair of elongated, parallel, spaced apart light sources each mounted on and spaced from one of said vertical reflector walls; an elongated arm pivotally mounted at a top end of said stanchion to extend forwardly therefrom, an elongated light source mounted on a bottom side of said arm, and means for fixing the angular relationship of said arm to said stanchion.
Claim 2
Dependent Claim 115 words
A portable illumination source and stand therefor including a wheel mounted base constituted as a rectilinear box having a front face and an opposite rear wall; a vertical stanchion fixedly mounted with respect to said rear wall, said stanchion having a pair of adjacent, integrally connected forwardly and outwardly facing vertical reflector walls; a pair of elongated, parallel, spaced apart light sources each mounted on and spaced from one of said vertical reflector walls; an elongated arm pivotally mounted at a top end of said stanchion to extend forwardly therefrom, an elongated light source mounted on a bottom side of said arm, and means for fixing the angular relationship of said arm to said stanchion.
Claim 3
Dependent Claim 23 words
The combination of claim 1 wherein said rectilinear box is constituted as a work stand having shelves open to the front face thereof.
Claim 4
Dependent Claim 73 words
The combination of claim 1 wherein said elongated arm has a pair of adjacent, integrally connected, downwardly and outwardly facing substantially horizontal reflector walls, said arm mounted light source includes a pair of elongated, parallel, spaced apart light sources each mounted on and spaced from one of said substantially horizontal reflector walls, and wherein said vertical reflector walls are situated at an obtuse angle from each other as are the substantially horizontal walls.
Claim 5
Dependent Claim 58 words
The combination of claim 3 wherein said means for fixing the angular relationship of the elongated arm to the vertical stanchion is constituted as a support rod adjustable as to length and pivotally mounted to said stanchion and to said arm at position adjacent and spaced from the point where the arm is pivotally supported on the stanchion.
Claim 6
Dependent Claim 23 words
The combination of claim 4 wherein said rectilinear box is constituted as a work stand having shelves open to the front face thereof.
Claim 7
Dependent Claim 49 words
The combination of claim 5 wherein the pivotal mounting of the arm to the stanchion is done using offset brackets so that, with the support rod disconnected, the elongated arm can be swung over the top of the stanchion and will assume position parallel to and adjacent the stanchion.
