Abstract
Abstract A current feeding rail element for electrified toy railway tracks including an elongated body of molded plastic material provided with a pair of current rails mounted on the top face and having fastening tongues extending through apertures in the body and bent over to form contact faces at the bottom face of the body, coupling ribs being provided at the bottom face of the body for detachably mounting a connector having corresponding coupling means and a pair of contact members adapted to contact a pair of rail-fastening tongues when the connector is clamped against the bottom face of the rail element.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
186 words
In a toy railway track comprising a plurality of sleeper elements and a pair of track rails mounted thereon an element detachably mounted on said sleepers intermediate said pair of track rails, said rail element comprising a body of electrical insulating material elongated in the direction of the track and having a top face and a bottom face, a pair of metallic currentfeeding rails mounted on the top face of said element, a plurality of metallic rail contacts mounted at the bottom face of said element and each connected with one of said current-feeding rails, on the top face of said element, a plurality of metallic rail coupling means at the said bottom face for detachably mounting said element on the sleeper elements, a connector comprising a plate of electrical insulating material and having a pair of metallic contact members mounted at one face thereof, leads connected with said contact members and coupling means for detachably mounting said connector on the bottom face of said rail element with its contact members contacting a pair of said rail contacts at the bottom face of said rail element.
Claim 2
Dependent Claim
186 words
In a toy railway track comprising a plurality of sleeper elements and a pair of track rails mounted thereon an element detachably mounted on said sleepers intermediate said pair of track rails, said rail element comprising a body of electrical insulating material elongated in the direction of the track and having a top face and a bottom face, a pair of metallic currentfeeding rails mounted on the top face of said element, a plurality of metallic rail contacts mounted at the bottom face of said element and each connected with one of said current-feeding rails, on the top face of said element, a plurality of metallic rail coupling means at the said bottom face for detachably mounting said element on the sleeper elements, a connector comprising a plate of electrical insulating material and having a pair of metallic contact members mounted at one face thereof, leads connected with said contact members and coupling means for detachably mounting said connector on the bottom face of said rail element with its contact members contacting a pair of said rail contacts at the bottom face of said rail element.
Claim 3
Dependent Claim
151 words
A current-feeding rail element, as defined in claim 1, and comprising an elongated body of molded plastic material and of substantially rectangular shape, said body having a top face carrying a pair of metallic current-feeding rails and a bottom face provided with ribs extending along the edges thereof, a central rib in the median plane of said bottom face and a plurality of transversely extending ribs located at regular intervals so as to define a plurality of rectangular recesses disposed symmetrically with respect to said central rib, an aperture in each of said recesses, said current feeding rails comprising continuous strips of thin sheet metal bent to a cross section of inverted U-shape and provided at one side with a plurality of bendable fastening tongues adapted to be inserted in said apertures and to be bent over so as to abut the bottom face of the rail element within said recesses.
Claim 4
Dependent Claim
44 words
A toy railway track, as defined in claim 1, in which the sleeper elements are rectangular plate elements made of molded plastic material and include a plurality of coupling studs adapted to engage the coupling means at the bottom face of said rail element.
Claim 5
Dependent Claim
70 words
A connector for a current-feeding rail element, as defined in claim 2, said connector comprising a plate element of rectangular shape and made of moldable plastic material, a pair of resilient contact members disposed symmetrically with respect to the longitudinal median plane of said plate element and coupling studs adjacent the corners of said plate element and adapted to engage the recesses at the bottom face of said rail element.
Claim 6
Dependent Claim
61 words
A current feeding rail element, as defined in claim 2, in which one end of each rail is provided with a pair of resilient tongues symmetrically disposed with respect to the median plane of the rail and extending lengthwise beyond the end of the rail so as to be adapted to be introduced into the cavity of an adjoinIng rail end.
