Abstract
A sliding contact for a toy rail vehicle has a body part having a convex slide face and a depression which is provided in the convex slide face and arranged so as to form on the latter an edge by which said slide face linearly contacts with a current-conductive rail and which removes extraneous particles from the current-conductive rail during sliding over the latter. The depression may have a circular cross-section so that the edge formed by the depression is annular. The depression may have a diameter which exceeds the width of the rail so that two curved edges are formed one of which is a leading edge, whereas the other of which is a trailing edge.
Claims5
A sliding contact for a toy vehicle, particularly for current transmission from a current-conductive rail of a toy railroad to an electric motor of the toy vehicle, the sliding contact comprising a body part which has an axis and a side arranged to face toward the current-conductive rail, said body part having a central portion located adjacent to said axis and provided with a depression which is open at said side, and a peripheral portion which surrounds said central portion has a convex face at said side, said convex face of said peripheral portion and said depression of said central portion intersecting one another to form an edge at the location of intersection, so that when said body part slides on the current-conductive rail, an unobstructed gap is formed between said convex face of said peripheral portion of said body part and the current-conductive rail, which gap is immediately followed by said edge linearly contacting the current-conductive rail, whereby said edge not only provides for contact with the current-conductive rail, but also removes extraneous particles from the latter.
