Abstract
Abstract Bar carrying electrical conductor is joined at one end to a coupling module adapted to be engaged on a rail and carrying electrical contact pieces designed to contact with conductors running along the rail, thereby ensuring: (a) the mechanical junction between the rail and the bar, and (b) the electrical connection between the conductors of the rail and the conductors of the bar. A connecting module and a hook are mounted on the bar, and both are adjustable along the bar. The connecting module has contact elements engaging conductors in the bar and a socket so that when an object to be lighted is suspended from the hook its plug can be inserted into the socket for an electrical connection through conductors in the bar to a source of electrical energy in the rail.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
215 words
Device for the suspension and lighting of objects comprising hanging means adapted to be hung on a horizontal rail and carrying electrical contact pieces designed to be brought into contact with electrical conductors running along the rail, whereby electrical connection between the conductors on the rail and lighting means operationally coupled to an object hooked on the hanging means can be ensured, said hanging means comprising: a bar with electrical conductors carried by said bar along the length thereof; hooking means for mounting said object on the bar, the position of said hooking means being adjustable along said bar, a coupling module mounted on one end of the bar and adapted to be engageable on the rail for suspending the bar and the object hanging thereon, said coupling module comprising contact pieces which are respectively connected to the conductors carried by the bar and which project from the coupling module so as to contact respectively with said conductors carried by the rail when said coupling module is engaged on said rail, and a connecting module mounted on the bar, the position of which is vertically adjustable along said bar, said connecting module comprising connecting elements adapted to be electrically connected to said lightening means and brought into contact with said conductors carried by the bar.
Claim 2
Dependent Claim
215 words
Device for the suspension and lighting of objects comprising hanging means adapted to be hung on a horizontal rail and carrying electrical contact pieces designed to be brought into contact with electrical conductors running along the rail, whereby electrical connection between the conductors on the rail and lighting means operationally coupled to an object hooked on the hanging means can be ensured, said hanging means comprising: a bar with electrical conductors carried by said bar along the length thereof; hooking means for mounting said object on the bar, the position of said hooking means being adjustable along said bar, a coupling module mounted on one end of the bar and adapted to be engageable on the rail for suspending the bar and the object hanging thereon, said coupling module comprising contact pieces which are respectively connected to the conductors carried by the bar and which project from the coupling module so as to contact respectively with said conductors carried by the rail when said coupling module is engaged on said rail, and a connecting module mounted on the bar, the position of which is vertically adjustable along said bar, said connecting module comprising connecting elements adapted to be electrically connected to said lightening means and brought into contact with said conductors carried by the bar.
Claim 3
Dependent Claim
44 words
Device as claimed in claim 1, wherein means are provided for signalling the unhooking of the object suspended on the bar by detecting the deconnection of the lighting device resulting from an interruption in the electrical connection with the electrical conductors of the rail.
Claim 4
Dependent Claim
38 words
The device of claim 1, wherein the conductors on the rail are enclosed in insulating material having grooves therein and the contact pieces on said coupling module project into the grooves to make electrical contact with the conductors.
Claim 5
Dependent Claim
29 words
The device of claim 1, wherein the rail defines a channel having the electrical conductors there within and said coupling module is adapted to be seated in the channel.
Claim 6
Dependent Claim
35 words
The device of claim 1, wherein the conductors in said bar are covered with insulating material and the connecting elements in said connecting module perforate the insulating material to make electrical contact with the conductor.
