Abstract
Abstract A low voltage light fixture for use with a multi-conductor wire, includes a base, a lens supported by the base, a pair of electrical conductors supported by the base which form a light bulb receptacle at their upper ends and wire engaging prongs at their lower ends, and a stake or post for supporting the base. A twist lock connector mechanism connects together the base, the stake and the wire.

Claim 1
Independent Claim
209 words
In a low voltage light fixture for use with a multi-conductor wire, having a base, a lens supported by the base, a pair of electrical conductors supported by the base and forming a light bulb receptacle at upper ends and wire engaging prongs at lower ends, and having a support for supporting the base, the improvement comprising: a first twist lock connector attached to a bottom surface of the base which includes a first pair of spaced connector elements, the first connector elements defining a first channel between them in which the wire is received and held and in which the prongs extend, and being positioned diagonally with respect to the first channel; and a second twist lock connector attached to the upper end of the stake which includes a second pair of connector elements, the second pair of elements defining a second channel between them and positioned diagonally with respect to the second channel, wherein (a) the second pair of spaced connector elements engage the first pair of spaced connector elements, (b) a passage, through which the wire extends, is formed by the first and second channels and maintained, and (c) the prongs electrically engage the wire, when the stake and base are rotated relative to one another.

Claim 9
Dependent Claim
37 words
The fixture of claim 1 and further comprising a sleeve positionable over an upper portion of the support to cover and protect portions of the wire leading to and from the first and second twist lock connectors.
Claim 10
Dependent Claim
93 words
A low voltage light fixture for use with a multiconductor wire, the light fixture comprising: a light fixture head having a first pair of twist lock connector elements which define a first wire receiving channel and having wire engaging conductors which extend into the first wire receiving channel; and a support for supporting the light fixture, the support having a second pair of twist lock connector elements which define a second channel and which engage the first pair of twist lock connector elements to connect together the light fixture head and the support.
Claim 11
Dependent Claim
93 words
A low voltage light fixture for use with a multiconductor wire, the light fixture comprising: a light fixture head having a first pair of twist lock connector elements which define a first wire receiving channel and having wire engaging conductors which extend into the first wire receiving channel; and a support for supporting the light fixture, the support having a second pair of twist lock connector elements which define a second channel and which engage the first pair of twist lock connector elements to connect together the light fixture head and the support.
Claim 12
Dependent Claim
41 words
The fixture of claim 9 wherein the first and second pair of twist lock connector elements connect the base to an upper end of the support when rotated with respect to one another from a first position to a second position.
Claim 13
Dependent Claim
17 words
The fixture of claim 10 wherein the first and second positions are less than approximately 90° apart.
