Abstract
Abstract A lighting track system for mounting to a vertical wall includes an elongated channel in the form of an inverted U with a horizontal web having an upper surface and connecting two depending legs, the channel retaining one or more electrical conductors extending therethrough, insulated from each other and the channel, and accessable for electrical connection from the open side of the channel. At least one of the vertical legs of the channel has an upstanding or depending flange that is provided with screws for attachment of the track to a vertical wall. An external source of power is connected to the electrical conductors, and one or more lighting fixture connectors mechanically attach and electrically connect to the track at any point along its length. In a preferred embodiment the track has a depending flange that terminates in an upturned lip for the support of suspended objects, such as paintings, wall hangings and drapes. An alternate preferred embodiment has both upstanding and depending vertical flanges for wall attachment.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
100 words
A lighting track system for mounting to a vertical wall including: an elongated channel in the form of an inverted U with a horizontal web having an upper surface and connecting first and second depending legs, the channel retaining one or more electrical conductors extending therethrough, connectable to a source of external power, insulated from each other and the channel and accessible for connection from the open side of the channel; means for attaching the first vertical leg to a wall; and means for making mechanical and electrical connection to the channel and conductors along the length of the track.
Claim 2
Dependent Claim
100 words
A lighting track system for mounting to a vertical wall including: an elongated channel in the form of an inverted U with a horizontal web having an upper surface and connecting first and second depending legs, the channel retaining one or more electrical conductors extending therethrough, connectable to a source of external power, insulated from each other and the channel and accessible for connection from the open side of the channel; means for attaching the first vertical leg to a wall; and means for making mechanical and electrical connection to the channel and conductors along the length of the track.
Claim 3
Dependent Claim
51 words
A lighting track system for mounting to a vertical wall according to claim 1 in which the means for attaching the first vertical leg to a wall is an upstanding rib contiguous at its proximal end with said first vertical leg and attachable to the wall with a plurality of screws.
Claim 4
Dependent Claim
53 words
A lighting track system for mounting to a vertical wall according to claim 1 in which the means for attaching the first vertical leg to a wall is an upstanding rib and a depending rib, both being contiguous with said first vertical leg and attachable to the wall with a plurality of screws.
Claim 5
Dependent Claim
50 words
A lighting track system for mounting to a vertical wall according to claim 1 in which the means for attaching the first vertical leg to a wall is a depending rib contiguous at its proximal end with one vertical leg and terminating at its distal end in an upturned lip.
Claim 6
Dependent Claim
28 words
A lighting track system for mounting to a vertical wall according to claim 1 in which the conductors are insulated wires retained in a partially enclosing elongated insulator.
Claim 7
Dependent Claim
29 words
A lighting track system for mounting to a vertical wall according to claim 1 in which the conductors are disposed in a parallel, spaced-apart relationship in the horizontal plane.
Claim 8
Dependent Claim
79 words
A lighting track system for mounting to a vertical wall according to claim 1 in which the conductors are disposed in a parallel, spaced-apart relationship in the horizontal plane, wherein the horizontal web of the channel is provided with an elongated, recessed groove in its upper surface which is horizontally located between the conductors, and the means for making mechanical and electrical connection to the channel and conductors along the length of the track is a lighting fixture connector.
Claim 9
Dependent Claim
63 words
A lighting track system for mounting to a vertical wall according to claim 7 in which a lighting fixture is electrically and mechanically coupled to the channel and the conductors by the lighting fixture connector urging a plurality of electrical contacts into engagement with the track conductors by the application of force against the recessed groove in the top surface of the channel.
Claim 10
Dependent Claim
41 words
A lighting track system for mounting to a vertical wall according to claim 8 in which the conductors are insulated wires and the electrical contacts are sharp-edged and make electrical contact with the conductors by piercing the insulation of the wires.
Claim 11
Dependent Claim
62 words
A lighting track system for mounting to a vertical wall according to claim 8 in which the lighting fixture connector is in the shape of a horizontal U, in which the electrical contacts are disposed in a first leg of the U and the force is applied against the recessed groove by a means disposed in the second leg of the U.
Claim 12
Dependent Claim
62 words
A lighting track system for mounting to a vertical wall according to claim 9 in which the lighting fixture connector is in the shape of a horizontal U, in which the electrical contacts are disposed in a first leg of the U and the force is applied against the recessed groove by a means disposed in the second leg of the U.
Claim 13
Dependent Claim
41 words
A lighting track system for mounting to a vertical wall according to claim 10 in which the force applying means is a sharp-pointed screw threaded through the second leg of the U and providing an electrical ground for the lighting fixture.
Claim 14
Dependent Claim
41 words
A lighting track system for mounting to a vertical wall according to claim 1 in which the second depending leg is provided with an elongated rib upstanding above the top surface of the horizontal web connecting the legs of the channel.
