Abstract
Abstract A locking assembly for lighting fixtures or portable lamps is provided to facilitate the fast assembly and alignment of longitudinally extending arms, such as hollow tubular arms, either on the flat surface, or on the vertical exterior surface of a base of the lighting fixture or portable lamp, without the use of additional machined or cast fittings. A bead is formed near the end of the arm, wherein the bead includes one or more indentations made of rectangular, square, round or other shapes, so that a projection or projections protrude from the opposite flat surface of the bead. The end of the tube beyond the bead is then threaded and if bent into an arm, the bending is done in the same plane as a line running through the center of the tube and one projection. One or more rounded holes slightly larger than the diameter of the tube are provided in the flat surface of the plates or bodies or onto the vertical sides of the bodies of the lighting fixture or portable lamp. These holes have on their circumferences one or more slotted or notched openings of such varying sizes and shapes so as to receive the ends of the longitudinally extending arms and the projections of the bead, so that location of these holes is quickly located and the arms are aligned with the hole or holes in relation to the plate or body.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
173 words
A lighting fixture or portable lamp assembly to facilitate the fast assembly and alignment of longitudinally extending arms to a base, said assembly comprising: a base; at least one longitudinally extending arm; said arm having a circumferential bead formed near an end of said at least one longitudinally extending arm; said bead having a flat surface thereon; said bead further having at least one indentation in positional register with at least one projection protruding from an opposite flat surface of said bead; said longitudinally extending arm having a threaded end located beyond said bead; and, said threaded end of said longitudinally extending arm being insertable within at least two bores in said base, one first bore of said at least two bores having at least one longitudinally extending notched slotted opening extending from an outer periphery of said first bore in said base, one further bore of said at least two bores having at least one wider notched slotted opening extending from said other periphery of said second, further bore in said base.
Claim 2
Dependent Claim
173 words
A lighting fixture or portable lamp assembly to facilitate the fast assembly and alignment of longitudinally extending arms to a base, said assembly comprising: a base; at least one longitudinally extending arm; said arm having a circumferential bead formed near an end of said at least one longitudinally extending arm; said bead having a flat surface thereon; said bead further having at least one indentation in positional register with at least one projection protruding from an opposite flat surface of said bead; said longitudinally extending arm having a threaded end located beyond said bead; and, said threaded end of said longitudinally extending arm being insertable within at least two bores in said base, one first bore of said at least two bores having at least one longitudinally extending notched slotted opening extending from an outer periphery of said first bore in said base, one further bore of said at least two bores having at least one wider notched slotted opening extending from said other periphery of said second, further bore in said base.
Claim 3
Dependent Claim
37 words
The assembly as in claim 1, said longitudinally extending arm being bent in the same plane as a line running through a center of said at least one longitudinally extending arm and said at least one projection.
Claim 4
Dependent Claim
38 words
The assembly as in claim 1, further comprising said at least one hole being slightly larger than a diameter of said longitudinally extending arm, said at least one hole being provided within a flat surface of said base.
Claim 5
Dependent Claim
66 words
The assembly as in claim 1, further comprising said base being an open outwardly extending three dimensional body, said body having a base wall and at least one side wall extending from said base wall, said at least one hole being slightly larger than a diameter of said longitudinally extending arm, said at least one hole being provided within said side wall of said base body.
Claim 6
Dependent Claim
64 words
The assembly as in claim 1 wherein said at least two bores have an inside circumferential edge therein, said at least two bores having on each said circumferential edges at least one notched slotted opening, said at least one projection of said at least one longitudinally extending arm being insertable within said at least one notched slotted opening of said at least one bore.
Claim 7
Dependent Claim
62 words
The assembly as in claim 1, further comprises a tightening nut and a spring lockwasher, said lockwasher being placed under said nut, said nut being tightened with sufficient torque so as to compress said spring lockwasher just enough to allow the arm to be swivelled out of position, for permitting said tubular arm of a multi-armed plate or body to be swivellable.
Claim 8
Dependent Claim
13 words
The longitudinally extending arm as in claim 1, wherein said arm is hollow.
Claim 9
Dependent Claim
13 words
The longitudinally extending arm as in claim 1 wherein said arm is tubular.
Claim 10
Dependent Claim
13 words
The longitudinally extending arm as in claim 1, wherein said arm is bent.
Claim 11
Dependent Claim
13 words
The base as in claim 1, wherein said base comprises a flat plate.
Claim 12
Dependent Claim
12 words
The base as in claim 4, wherein said body is a cylinder.
Claim 13
Dependent Claim
11 words
The base as in claim 4, wherein said body is open.
Claim 14
Dependent Claim
65 words
The assembly as in claim 1 further comprising a means to swivel said at least one longitudinally extending arm, said means comprising a spring lockwasher being applied with a predetermined torque to compress said spring lockwasher, said compression of said spring lockwasher permitting said at least one longitudinally extending arm to swivel from a first position to a second position with respect to said base.
Claim 15
Dependent Claim
29 words
The assembly as in claim 1, wherein said at least one longitudinally extending arm is bent in a plane coaxial with a center axis of said longitudinally extending arm.
