Abstract

Abstract A model track section for model vehicles releasably interengageable in end-to-end connection with a like track section, wherein an end formation is provided having one side facing generally laterally, and resilient means is located obliquely along the laterally facing side for resilient deflection laterally toward the formation upon end-to-end interengagement of like track sections.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 228 words
A track section for model vehicles comprising an elongate body, vehicle support means extending longitudinally on said body, a formation on each end of said body having one side facing generally laterally and provided with a generally laterally facing concavity, resilient means on said one side of each of said formations extending obliquely therefrom toward said body across the concavity of said formation and being deflectable laterally toward the concavity of the associated formation, interengagement means on each end of said body configured to cooperate with said formation for removable interengagement in end-to-end relation with a like track section with said resilient means deflected laterally toward the adjacent concavity, said resilient means comprising an obliquely disposed conductive metal strip portion, said interengagement means and formations being configured to guide a like track section longitudinally into and out of said end-to-end relation at an angle with respect to said metal strip portions for laterally deflecting the latter toward said concavities, and an additional conductive metal strip portion extending inwardly from said oblique metal strip portion longitudinally along said body and having its opposite end portion exposed laterally for bearing engagement with an oblique metal strip portion of a like track section, said obliquely disposed metal strip portion and said additional conductive metal strip portion being an integral length of resiliently deflectable strip material substantially straight in its undeflected condition.
Claim 2
Dependent Claim 228 words
A track section for model vehicles comprising an elongate body, vehicle support means extending longitudinally on said body, a formation on each end of said body having one side facing generally laterally and provided with a generally laterally facing concavity, resilient means on said one side of each of said formations extending obliquely therefrom toward said body across the concavity of said formation and being deflectable laterally toward the concavity of the associated formation, interengagement means on each end of said body configured to cooperate with said formation for removable interengagement in end-to-end relation with a like track section with said resilient means deflected laterally toward the adjacent concavity, said resilient means comprising an obliquely disposed conductive metal strip portion, said interengagement means and formations being configured to guide a like track section longitudinally into and out of said end-to-end relation at an angle with respect to said metal strip portions for laterally deflecting the latter toward said concavities, and an additional conductive metal strip portion extending inwardly from said oblique metal strip portion longitudinally along said body and having its opposite end portion exposed laterally for bearing engagement with an oblique metal strip portion of a like track section, said obliquely disposed metal strip portion and said additional conductive metal strip portion being an integral length of resiliently deflectable strip material substantially straight in its undeflected condition.
Claim 3
Dependent Claim 76 words
A track section according to claim 1, said formations each having its other side facing oppositely laterally, and additional resilient means on the other side of each formation extending obliquely toward said body and being deflectable laterally toward the associated formation, said interengagement means including laterally spaced facing portions respectively engageable with said first-mentioned and additional resilient means of a like track section to laterally deflect both resilient means upon longitudinal end-to-end interengagement of track sections.
Claim 4
Dependent Claim 47 words
A track section according to claim 1, in combination with a bearing portion on said body adjacent to and spaced from each of said one formation sides and in bearing engagement with the adjacent resilient strip portion to hold the latter in position across the associated concavity.
Claim 5
Dependent Claim 97 words
A track section according to claim 1, in combination with an additional pair of conductive resilient metal strip portions each extending longitudinally along said body from the inner end of a respective first mentioned resilient strip portion the distal end portion of each of said additional strip portions being exposed laterally on the side toward each other for bearing engagement with said first mentioned strip portions of a like track section, and additional formations on each end of said body in resilient backing engagement with said distal end strip portions on the sides away from each other.
Claim 6
Dependent Claim 31 words
A track section according to claim 4, said first mentioned and additional formations extending longitudinally of said body beyond said first mentioned and additional strip portions to effectively protect the latter.
