Adaptor for an electrical power distributor track

Claim 2

An adaptor for an electrical power distribution track adapted to be fitted into the open channel of the said track in a first position and adapted to be rotated to a second position for making electrical contact therewith, said adaptor comprising spring loaded contact means for making contact with electrical power lines in said track, holding elements on said adaptor adapted to be located in recesses provided in the track, and means for locking the adaptor into position, said adaptor having an electrical selector contact which can be variably positioned for selectively making contact with different power lines in said track, said selector contact being assembled in a rotatable part arranged to selectively provide conTact with an upper and/or lower power line on either side of the distribution track channel, and said selector contact being connected in the adaptor to current conducting parts operative to conduct current to the consuming element.

Claim 3

The adaptor of claim 1 including means for locking the rotatable part in the selector position.

Claim 4

The adaptor of claim 1 wherein said selector contact is a blade-like contact which surrounds said current conducting parts.

Claim 5

The adaptor of claim 3 wherein said blade-like contact surrounds a rod having parallel flat sides.

Claim 6

The adaptor of claim 1 including spring means for holding the selector contact against the power line of the distribution track by spring pressure.

Claim 7

The adaptor of claim 1 including means for locking the rotatable part in position so as to prevent rotation of said part relative to neighboring parts of the adaptor.

Claim 8

The adaptor of claim 5 in which said rotatable part and said neighboring parts are provided with complementarily shaped surfaces to achieve the locking function.

Claim 9

The adaptor of claim 1 including a cap for securing the rotatable part in a desired position.

Claim 10

The adaptor of claim 1 in which an outwardly spring-loaded contact lug is provided for making contact with a ground line in said track.

Claim 11

The adaptor of claim 1 in which said holding elements comprise a plurality of lugs, the opposite sides of the adaptor being provided with different numbers of such lugs.

Claim 12

The adaptor of claim 1 including a clamping part mounted for slidable motion along said adaptor, said clamping part being held against rotation on the base of the adaptor, said clamping part being arranged to be clamped to the underside of the power distribution track.

Claim 13

An adaptor for an electrical power distribution track adapted to be fitted into the open channel of the said track in a first position and adapted to be rotated to a second position for making electrical contact therewith, said adaptor comprising spring loaded contact means for making contact with electrical power lines in said track, holding elements on said adaptor adapted to be located in recesses provided in the track, a clamping part mounted for slidable motion along said adaptor, said clamping part being held against rotation on the base of the adaptor and said clamping part being arranged to be clamped to the underside of the power distribution track to lock the adaptor into position, said adaptor having an electrical selector contact which can be variably positioned for selectively making contact with different power lines in said track, said selector contact being connected in the adaptor to current conducting parts operative to conduct current to the consuming element.

Claim 14

An adaptor for an electrical power distribution track adapted to be fitted into the open channel of the said track in a first position and adapted to be rotated to a second position for making electrical contact therewith, said adaptor comprising spring loaded contact means for making contact with electrical power lines in said track, holding elements on said adaptor adapted to be located in recesses provided in the track, a clamping part mounted for slidable motion along said adaptor, said clamping part being held against rotation on the base of the adaptor and said clamping part being arranged to be clamped to the underside of the power distribution track to lock the adaptor into position, said adaptor having an electrical selector contact which can be variably positioned for selectively making contact with different power lines in said track, said selector contact being connected in the adaptor to current conducting parts operative to conduct current to the consuming element.

Claim 15

The adaptor of claim 1 including spring means for holding the selector contact against the power line of the distribution track by spring pressure.

Claim 16

The adaptor of claim 12 in which an outwardly spring-loaded contact lug is provided for making contact with a ground line in said track.

Claim 17

The adaptor of claim 12 in which said holding elements comprise a plurality of lugs, thie opposite sides of the adaptor being provided with different numbers of such lugs.

Claim 18

The adaptor of claim 12 wherein said selector contact is a blade-like contact which surrounds said current conducting parts.

Claim 19

The adaptor of claim 16 wherein said blade-like contact surrounds a rod having parallel flat sides.
