- (i) a pair of spaced slots extending partway along the lower horizontally extending wall of the socket so as to define a resilient portion of the lower wall,
- (j) a cut-out in the resilient portion positioned to receive the detent of the plug, the detent being shaped and arranged to resiliently deform the resilient portion as two track sections are being joined until the detent enters the cut-out, to thereby enable a mechanical interlocking of two track sections, and
- (k) a resilient electrically conductive strip electrically connected to one of the rails and extending downwardly across each socket, whereby when two track sections are joined together, the strip contacts the plate of the plug fitted into the socket.
- 2. A track section as claimed in claim 1 wherein the detent is formed as a round projecting member, wherein the cutout is formed as a round hole dimensioned so as to receive the round member within the hole.
- 3. A track section as claimed in claim 1 wherein the means electrically connecting the plate and the strip each include a portion extending under a corresponding one of the conductive rails, and are held in electrical connection with the rails by being sandwiched between the base and the rails.
- 4. A track section according to claim 1, wherein the means electrically connecting the conductive plate with one of the rails includes first means for resiliently engaging the rail, wherein the resilient electrically conductive strip includes second means for resiliently engaging the other of the rails, and wherein the base includes a cutout beneath ends of the rails dimensioned and arranged so that the ends of the rails extend over the cutouts for providing space for receiving a fishplate, whereby the first and second means for resiliently electrically connecting can be resiliently moved out of contact with their respective rails when fishplates are received in the cutouts beneath the ends of the rails.
- 5. A toy railroad track section for end-to-end connection with another, adjoining track section for forming a continuous toy railroad track, the section comprising: an elongate plastic base; a pair of spaced apart, electrically conductive rails attached to and supported by the base and extending over the length thereof from one end of the base to another end thereof; and connector means for securely mechanically interlocking adjacent track sections and for forming an electric connection between respective tracks on the sections, the connector means including an aperture formed in each end of the base and extending generally in the direction of the track section, the aperture being defined by walls of the base which completely surround at least a portion of the cross-section of the aperture proximate the corresponding end of the base; an electrically conductive strip constructed of a resilient material, a first portion of the strip being attached to the base and a second portion of the strip extending generally in the direction of the aperture and protruding into the cross-section thereof, the second portion being disposed entirely within the aperture so as to protect it from accidental contact and damage; means for establishing an electrical connection between the strip and the associated track attached to the base; a relatively rigid plug projecting from each end of the base, the plug being dimensioned to snugly fit into a corresponding aperture of an adjoining track section, the plug having a length adapted to be received within the aperture and including a depression located to be in substantial alignment with the second portion of the conductive strip protruding into the corresponding aperture cross-section of the adjoining track section, the depression being defined by a base member of the plug so that the plug can be slidably inserted into the aperture and the base member can resiliently deflect the second portion of the conductive strip if the two come in contact with each other; an electrically conductive plate disposed within the depression carried by the base member; the base member and the plate having a combined thickness so that the latter contacts and resiliently deflects the second portion of the conductive strip when the plug is inserted into the aperture; means attaching the plate to the base of the track section; and means for electrically connecting the plate with the corresponding track of the section; whereby the insertion of the plug in a corresponding aperture of the adjoining track section simultaneously causes a secure interlocking of the plug and the walls defining the aperture cross-section and, therewith of the adjoining track sections, and the establishment of an electric connection between corresponding tracks of adjoining sections via the plates and the strips.
- 6. A toy railroad section for the end-to-end connection with another, adjoining track section for forming a continuous toy railroad track, the section comprising:
- an elongate plastic base;
- a pair of spaced apart, electrically conductive rails attached to and supported by the base and extending over the length thereof from one end of the base to another end thereof; the base including adjacent its ends and beneath the respective rails depression dimensioned and arranged so that the ends of the rails extend over the depression to provide space for receiving a fishplate;
- and connector means for securely mechanically interlocking adjacent track sections and for forming an electric connection between respective rails on the sections, the connector means including
- (a) an aperture formed in each end of the base and defined by integrally constructed upper and lower, generally horizontally disposed walls and upright side walls interconnecting the horizontal walls to give the aperture a fully defined cross-section, the aperture extending from the corresponding end of the base towards the other end thereof;
- (b) a pair of spaced slots in the portion of each base defining an aperture, each pair of slots being arranged to separate a portion of the associated lower wall from the adjoining upright walls so as to render such portion of the lower wall resiliently deformable;
- (c) a cutout in the resilient portion of each lower wall;
- (d) a resilient, electrically conductive strip attached to each of the base and having a deflectable portion wholly disposed within the aperture at the corresponding base end, the deflectable portion extending generally in the direction of the aperture and into the cross-section thereof so as to define a free end of such deflectable portion which is spaced from the portion of the base to which the strip is attached;
- (e) a plug protruding from each end of the base for insertion into an aperture in the adjoining track section, the plug having a generally U-shaped profile defined by spaced apart upright side portions and a base member interconnecting ends of the side portions, the side portions having outer surfaces spaced apart to be snugly received by the upright side walls of the aperture, the profile of the plug further defining a recess positioned and oriented so as to receive the deflectable portion of the strip when the plug is inserted into an aperture;
- (f) a detent projecting from a side of the base member facing away from the recess, the detent being positioned and formed to be received within the cutout when the plug is inserted into the aperture and to engage and resiliently deflect the resilient portion of the lower wall when the plug is disposed within the aperture and the detent is outside the cutout;
- (g) an electrically conductive plate carried by the base member and disposed within the recess of the plug, the base member and the plate having a combined thickness so as to engage and deflect the free end of the deflectable strip portion to thereby establish an electric connection between the strip and the plate;
- whereby the insertion of the plug in an aperture of the adjoining track section initially causes the resilient deflection of the resilient lower wall portion and thereafter causes a snap-in engagement between the detent and the cutout to thereby mechanically interlock the track sections and simultaneously establish an electric connection between the strip and the plate;
- (h) first means electrically coupled to the plates and at least partially disposed within the depression in the base for beneath one of the rails resiliently contacting the corresponding rail to electrically couple the plate with such rail;
- (i) second means electrically coupled with the strip and at least partially disposed within the depression beneath the other one of the rails for resiliently contacting the other rail to electrically couple the strip with such other rail;
- whereby the adjoining track sections can be mechanically and electrically coupled by inserting corresponding plugs of the sections and corresponding apertures thereof; and whereby the track section can further be coupled with another track element having interconnected rails but being devoid of plugs and apertures by slipping fishplates in the depressions to engage the rails overlying the depressions and engaging with such fishplates the rails of the other track element.
