Abstract
Abstract An angle piece for a contact rail of U-shaped section and provided with longitudinal conductors. The L-shaped angle piece can be pushed into the groove of two contact rails forming an angle between them, thereby establishing contact between the conductors of the two rails via contact fingers provided on an installation component of the angle piece supported by a body portion. The installation component can be shifted in relation to the body portion diagonally so as to adjust the relative position of the contact fingers to flanks of the body portion.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
168 words
An angle piece for a contact rail, comprising: the rail including a support body of U-shaped section having longitudinal conductors placed in a longitudinal groove of said support body eccentrically in relation to sides of said support body, said angle piece having end, portions and an L-shaped body portion which can be pushed into said groove of the support body longitudinally, said L-shaped body portion having at each end portion contact fingers for contacting the conductors in the support body, said contact fingers being placed eccentrically in relation to inner and out flanks of the L-shaped body portion an L-shaped installation component, said contact fingers being mounted onto said installation component supported by said L-shaped body portion and being adjustable in relation to said body portion, said L-shaped installation component being shiftable in relation to the body portion in its diagonal direction so that said contact fingers can be selectively adjusted for coming closer to the inside flank or closer to the outside flank of the body portion.
Claim 2
Dependent Claim
168 words
An angle piece for a contact rail, comprising: the rail including a support body of U-shaped section having longitudinal conductors placed in a longitudinal groove of said support body eccentrically in relation to sides of said support body, said angle piece having end, portions and an L-shaped body portion which can be pushed into said groove of the support body longitudinally, said L-shaped body portion having at each end portion contact fingers for contacting the conductors in the support body, said contact fingers being placed eccentrically in relation to inner and out flanks of the L-shaped body portion an L-shaped installation component, said contact fingers being mounted onto said installation component supported by said L-shaped body portion and being adjustable in relation to said body portion, said L-shaped installation component being shiftable in relation to the body portion in its diagonal direction so that said contact fingers can be selectively adjusted for coming closer to the inside flank or closer to the outside flank of the body portion.
Claim 3
Dependent Claim
29 words
An angle piece as claimed in claim 1, wherein said L-shaped body portion has diagonal guide grooves and said installation component has guide pins penetrating into said guide grooves.
Claim 4
Dependent Claim
57 words
An angle piece as claimed in claim 1 wherein conductors in the contact rail are mounted on an insulating list projecting from the bottom of the support body, said insulating list having a slit means for receiving a counter-projection placed on the angle piece, said counter-projection on the angle piece being placed on the adjustable installation component.
