Definitions

  • a model train track section is there generally designated 10.
  • Figures 2 and 3 there is associated with the track section 10 a like track section 10a, wherein corresponding parts of the like track section are designated by corresponding numerals plus the letter "a".
  • the track section 10 includes an elongate plastic or otherwise non-conductive bed 11, which may be generally flat and of elongate straight, curved, or other desired configuration.
  • the bed 11 may advantageously be automatically fabricated, as by injection molding, either in an elongate straight or curved configuration, as for forming straight or curved track sections.
  • the lower and upper surfaces of the bed 11 may be generally flat, and substantially coplanar, while the bed may be provided with a plurality of side edge cutouts, as 12, and a plurality of intermediate cutouts 13, all configured and arranged to present the simulated appearance of railroad ties 14.
  • each longitudinal side edge of bed 11 there are provided a plurality of side edge cutouts 12, with the cutouts of opposite side edges being in laterally spaced, aligned relation with each other.
  • the laterally intermediate cutouts 13 are arranged in a row along the laterally intermediate region of bed 11, each laterally intermediate cutout 13 being laterally aligned with and in spaced relation between a pair of laterally aligned side edge cutouts 12.
  • the laterally extending remaining bed regions 14 present the appearance of a plurality of generally parallel spaced railroad ties arranged in a row longitudinally of the track section 10 and each adjacent pair of simulated ties 14 is connected together by a pair of longitudinally extending laterally spaced bed portions 15.
  • a pair of longitudinally extending, parallel spaced track rails 20 are superposed on the bed 11, respectively directly over each series of aligned tie connecting bed portions 15 in crossing relation with the several ties 14.
  • rail attachment means as at 21, simulating the appearance of clamps serving to attach the rails 20 to the bed 11.
  • each bed 11 may be substantially identical, as best seen in Figure 1. It will there be apparent the the end most simulated tie 14 is connected to the next endmost simulated tie 14 by a generally flat bed portion or web 25.
  • the web 25 may extend between the pair of endmost simulated ties.14, and substantially between the ends thereof, except for certain cutouts and openings.
  • a notch or cutout 27 In general alignment with one aligned tow of tie connecting portions 15, extending inwardly from the outer side 26 or end most surface of bed 11, there is formed a notch or cutout 27.
  • the notch or cutout 27 is undercut, as at 28.
  • the undercut inner side of cutout or notch 27 has its mouth or opening bevelled, as at 29, extending inwardly from the edge 26 to define between the bevel 29 and undercut 28 a lobe, protrusion or lug 30.
  • a notch, slot or slit 31 Spaced laterally inwardly from the cutout 27, adjacent to the undercut inner side thereof, there is formed a notch, slot or slit 31 extending longitudinally of the bed 11 inwardly from the bed edge 26 to a location adjacent to and short of the next adjacent simulated tie 14.
  • the slot or kerf 31 is sufficiently close to the cutout 27 to leave the bed region therebetween, designated 32, at least slightly resilient, for resiliently yieldable deflection of the lug 30, for a purpose appearing presently.
  • the end protrusion or extension 35 includes a generally rectangular inner portion 36 extending directly from and generally normal to the surface 26 of endmost tie 14, and a reduced terminal portion 37 extending from the inner portion 36 longitudinally outwardly of the bed 11, spaced laterally from the side edges of the inner portion.
  • the terminal portion or reduced projection 37 being spaced laterally between the side edges of portion 36 defines on the latter a pair of longitudinally outwardly facing, respectively laterally inner and outer shoulders 38 and 39.
  • the reduced portion or extension 37 may have one side edge generally straight, as at 40, generally longitudinally of the bed 11, and may have its other, inner side provided with an undercut or recess 41, and which may extend longitudinally inwardly from its distal or outer end 42 in the manner of a bevel or chamfer 43.
  • the region of extension 35 between undercut or recess 41 and bevel 43 may define a lateral protrusion or lug 44.
  • a through opening or hole 45 may be formed laterally medially in the projecting portion 36, extending inwardly therefrom through the adjacent portion of tie 14 and thence into the adjacent portion of web 45. Also, an opening or through hole 45 may be formed in the web 25, spaced between the endmostand next adjacent ties 14, and the opening 45 and slot 31.
  • each rail 20 may be substantially identical, each being fabricated of metal or. other suitably conductive material and of a substantially constant cross sectional configuration throughout its length.
  • each rail 20 may include a generally flat lower flange or base 50 which rests on and traverses the several ties, an upstanding intermediate region or web 51 upstanding from the base laterally medially thereof, and an enlarged upper portion or head 52.
  • the attachment means or simulated rail clamps 21, except those on the endmost tie 14 designated 21', are advantageously formed integral with the respective tie and configured to define a tongue or lip 53 in overlying retaining engagement with the adjacent base portion 50 of rail 20.
  • the lips or tongues 53 of the attachment means 21 serve to retain the rails 20 in position on the bed 11.
  • the rails 20 are generally parallel to each other and coterminous. Each rail 20 terminates at a location approximately midway between the distal end 42 of extension 35 and the innermost region of cutout 27. Thus, as may be seen in Figure 2, both of the rails 20 terminate at ends 54, laterally aligned with each other, which ends extend longitudinally outwardly beyond the endmost tie 14.
  • the simulated rail clamps or attachment means 21' of the endmost tie l4 are lacking in the retaining lip or tongue 53 of the attachment means 21, so that the end portions of rails 20 extending beyond the second endmost tie 14 are free of the bed, without restraint of one by the other.
  • the bed portion 32 is relatively free to flex toward the slot 31 for reduction of the latter.
  • the end extension 35 is aligned with the end cutout or receiver 27a, and similarly the end cutout or receiver 27 is aligned with the end extension 35a.
  • the extensions 35 and 35a will enter into the receivers 27a and 27, respectively, during which the bosses or lugs 30 and 30a will be resiliently deflected laterally by respective bosses or lugs 44a and 44, for snap engagement thereby and resilient retention of the end extensions in respective end receivers.
  • each rail 20 is provided on one end with a conductive rail connector or joiner 60.
  • the rail joiner-60 is fixedly attached to the rail end. portion which terminates generally over the extension 35 when the rail sections are not connected.
  • the rail joiners or connectors 60 are permanently connected to the rail end portions which terminate over the bed openings 45.
  • the rail connectors or joiners 60 may each include an elongate, upwardly facing clip having a bottom wall 61 engaged beneath the rail base 50, and upstanding spring flanges or fingers 62 on opposite sides of and engaging adjacent upper portions of the rail base. Further, the rail connectors or joiners 60 extend considerably beyond the end 54 of the rail 20, terminating adjacent to and just short of the distal end 42 of the end extension 35.
  • a resilient lip or leaf spring 63 extends from the outer end of the bottom wall 61 of each joiner 60 for snap engagement into a nether recess 47, for positive retention thereby on the associated rail end portion.
  • the track section 110 may include a generally flat, non-conductive base part or bed 111, which may be fabricated of plastic, say by injection molding, or otherwise fabricated of other suitable material.
  • the bed 111 is generally elongate and provided on opposite side edges with a series of cutouts or notches 112, with the notches of opposite side edges being in respective laterally aligned relation with respect to each other.
  • bed 111 is provided, laterally medially thereof, with a longitudinal row of through holes or openings 113, each being elongate laterally of the bed and in respective alignment with and between a pair of laterally aligned side edge cutouts or notches 112.
  • the bed material remaining between side edge cutouts 112 and laterally medial openings 113 define a plurality of parallel spaced, laterally extending simulated ties 114 arranged in a row longitudinally of the bed. Also, connecting the ties 114 are an aligned series or row of bed portions 115 adjacent to and spaced inwardly from each side edge of the bed.
  • a pair of laterally spaced, parallel rails 120 Superposed over the bed 111, extending longitudinally thereof, are a pair of laterally spaced, parallel rails 120.
  • the rails 120 may each overlie an aligned row or series of connecting bed portions 115, so as to obscure the later, leaving visible only the rails and underlying transverse ties 114 to accurately simulate full size railroad track, in the same manner as the first described embodiment.
  • each simulated tie 114 except the endmost tie 114 is provided with rail attachment members 121 which each include a retaining projection or lip 153 overlying the adjacent portion of the rail base and thereby retaining the rail in position on the bed.
  • the endmost ties 114 include simulated rail clamps 121' which are not provided with retaining lips, and so do not function to retain or attach the rail 120 to the bed, but only as a clamp simulation.
  • Each end region of bed 111 is provided with a web or connecting portion 125 between the endmost and next adjacent ties.
  • the endmost tie 114 may have its side edge 126 facing away from the next adjacent tie 114 and provided with a longitudinally inwardly extending opening 127 beneath one rail 120. More specifically, the cutout, opening or receiver 127 extends longitudinally inwardly of the bed 111 through endmost tie 114 and into web 125, terminating short of the next adjacent tie 114.
  • the side walls of the cutout or receiver 127 are each undercut, as at 128, and provided with an internal projection or lug 130 which flares or chamfers outwardly, as at 129 to the tie surface 126.
  • a pair of guide members 133 extending from the tie surface 126 on opposite sides of cutout or receiver 127 are a pair of guide members 133 defining therebetween a guideway opening into the receiver 127.
  • the bed is provided with a dual or split end extension 135 projecting longitudinally outwardly from the bed end surface 126.
  • the bed end extension 135 is subdivided or split by an opening 145 extending longitudinally of the bed inwardly through the end extension 135, thence through the endmost tie 114 and into the bed region 125 terminating short of the second endmost tie 114.
  • the cutout or opening 145 subdivides the end extension 135 into a pair of laterally spaced resiliently deflectable fingers or detent elements 137.
  • Each projection finger 137 may have its outermost or distal end 142 somewhat rounded and provided on its outer side with a bevel or chamfer 143 extending from the distal end 142.
  • the outer surface or edge 138 of each spring finger 137 is notched or undercut, as at 141 spaced inwardly from the adjacent bevel 143 and combining therewith to define a laterally outstanding projection or lug 144.
  • the simulative but inoperative rail clamps 121' are located on opposite sides of the opening 145, on the endmost tie 114.
  • An additional simulative but inoperative pair of rail clamps 136 are provided on the upper surfaces of spring fingers 137, each aligned with a respective rail clamp 121' longitudinally of the bed and spaced therefrom the approximate center-to-center spacing of the ties.
  • the rail clamps 136 are lacking,in the hereinbefore described retaining tongues so as to be simulative, but without the attachment function.
  • spring fingers 137 are provided with recess 147 opening laterally into the cutout 137, for a purpose appearing presently.
  • the track section 111 is adapted for end to end interfitting engagement with an aligned, like track section 111a, wherein the longitudinal end extension 135 enters into and interfits within a longitudinal end receiver 127a, and similarly the longitudinal end receiver 127 receives in interfitting engagement a longitudinal end projection 135a. That is, each end projection 135 is laterally offset from the longitudinal centerline of the track section 110 a distance equal to the lateral offset of the end receivers 127 for mating engagement with the like track section 110a. Also, the end extension fingers 137 mayresiliently flex toward each other for snap engagement of the finger lugs 144 past the receiver lugs 130 into a resilient retaining engagement therebetween.
  • the finger lugs 144 snap into the receiver undercuts 128, and the receiver lugs 130 snap into the finger undercuts 141.
  • the track sections are thereby effectively retained in their aligned end to end interfitting relation throughout all conditions of use, while permitting of deliberate disconnection or separation by mere longitudinal withdrawel of the parts, one from the other.
  • the rails 120 are longitudinally coterminous, with their ends 154 located approximately midway longitudinally of the track section between the distal end 142 of an end extension, and the distal end 142a of a received end extension.
  • rail connectors or joiners 160 are provided on one end of each rail section 120. Specifically, the end portion of each rail section 120 over the cutout 145 of end projection 135 is provided with a rail connector or joiner 160.
  • the rail connectors or joiners 160 may be substantially identical to the joiners or connectors 60 of the first described embodiment, and provided with spring clips 162 in retaining engagement with the rail base, and a resilient end tab 163 in self-retaining end engagement within recesses 147.
  • the clips 160 are effectively positively retained in position on the rails 120 extending over the end extensions 135. That is, upon end engagement of like track sections 110 a rail end portion without a joiner 160 will enter into the extending end of a joiner 160, and withdraw therefrom upon track section disconnection leaving the joiner on its original rail end portion.
  • the rail end joiners 160 do not extend beyond their adjacent, underlying end extensions 135. Also, the rail end portions without rail joiners do not extend beyond their adjacent underlying guide members 133, so that there are no possibly injurious rail or connector extensions beyond the bed 111.
  • the present invention provides a model train track construction which includes the safety of having no sharp protrusions, is entirely vibration proof under all operating conditions while permitting of deliberate disconnection when desired, and wherein the rail connectors or joiners are effectively self-anchoring in position for ready track section connection and disconnection.
