Abstract

Abstract A toy track for use with electrically operated self-propelled toys such as vehicles or railway trains comprising a plurality of track section, each track section including at least one pair of electrically conductive rails extending substantially the length of the section and provided at least at one end with an electrical junction means adapted to be joined with a corresponding electrical junction means on the adjacent section, said junction means comprising on the one section an insulating member which protrudes from the end of the track section in overlapping relationship with the adjacent track section and on the adjacent track section a recess adapted to receive said projecting portion, said projecting portion mounting and projecting beyond at least one electrically conductive member for coupling a conductive rail of the respective track section with the conductive rail of the adjacent track section.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 278 words
A toy track for use with electrically operated self-propelled toys such as vehicles or railway trains, said toy track including a plurality of track section, each track section comprising a pair of electrically conductive rails extending substantially the length of said track section, said rails being mounted on a base, electrical connection members connected to one end of said conductive rails, at least one of said electrical connection members extending beyond the end edge of said base, and said electrical connector members being adapted to join with a pair of electrically conductive rails on an adjacent track section, a safety projection member connected to said track section closely adjacent said electrical connector member, said safety projection member being comrised of a base wall and opposed side walls only with the electrical connector member positioned between the side walls, that structure of said projection member exposing said electrical connection members to view when said track section is unconnected to an adjacent track section and when said track section is viewed from a line of sight that permits viewing of and is perpendicular to the track surface over which said toys are adapted to move, and said base wall and side walls extending from the end edge of said base beyond the exposed end of said electrical connection member for preventing contact of that end of said electrical connection member with a user when said track section is unconnected to an adjacent track section, and retaining means formed integral with said safety projection member, said retaining means being adapted to cooperate with an adjacent track section for connecting together said track section and an adjacent track section in operative relation.
Claim 2
Dependent Claim 278 words
A toy track for use with electrically operated self-propelled toys such as vehicles or railway trains, said toy track including a plurality of track section, each track section comprising a pair of electrically conductive rails extending substantially the length of said track section, said rails being mounted on a base, electrical connection members connected to one end of said conductive rails, at least one of said electrical connection members extending beyond the end edge of said base, and said electrical connector members being adapted to join with a pair of electrically conductive rails on an adjacent track section, a safety projection member connected to said track section closely adjacent said electrical connector member, said safety projection member being comrised of a base wall and opposed side walls only with the electrical connector member positioned between the side walls, that structure of said projection member exposing said electrical connection members to view when said track section is unconnected to an adjacent track section and when said track section is viewed from a line of sight that permits viewing of and is perpendicular to the track surface over which said toys are adapted to move, and said base wall and side walls extending from the end edge of said base beyond the exposed end of said electrical connection member for preventing contact of that end of said electrical connection member with a user when said track section is unconnected to an adjacent track section, and retaining means formed integral with said safety projection member, said retaining means being adapted to cooperate with an adjacent track section for connecting together said track section and an adjacent track section in operative relation.
Claim 3
Dependent Claim 39 words
A toy track according to claim 1 wherein said projection member of said track section is adapted to be joined with a corresponding recess in an adjacent track section in a direction parallel to the plane of the track.
Claim 4
Dependent Claim 93 words
A toy track according to claim 2 further comprising detent means for resisting the separation of adjacent track sections, said detent means comprising a raised boss on a projection portion of said track section which projects in a plane parallel to the plane of said track section and a thin walled portion bounding a recess in the adjacent track section, said recess being arranged to slidingly receive said projection portion when the track sections are joined, said track sections being so designed as to allow resilient relative displacement of the thin walled portion.
Claim 5
Dependent Claim 59 words
A toy track according to claim 1 wherein said track section is provided with said safety projection member at one end and a recess at the other end, said recess being structured to receive the safety projection member and the electrical connection member of an adjacent track section when said track section is connected to said adjacent track section.
Claim 6
Dependent Claim 32 words
A toy track as claimed in claim 4 wherein the connection members at least partially extend the length of the conductive rail and are riveted, staked or crimped to a conductive rail.
Claim 7
Dependent Claim 33 words
A toy track as claimed in claim 1 wherein the connection members extend only a part of the length of the conductive rails and are riveted, staked or crimped to the conductive rails.
Claim 8
Dependent Claim 19 words
A toy track according to claim 1 wherein the conductive rails are contained in slots in a track base.
Claim 9
Dependent Claim 37 words
A toy track according to claim 7 wherein the conductive rails are secured to the track base through apertures in the base by riveting, crimping or staking the said rail on the underside of the track base.
Claim 10
Dependent Claim 44 words
A toy track according to claim 8 wherein the rails are also secured to the track base by means of metal shoes which are positioned in the said apertures and themselves have apertures through which riveting, crimping or staking of the rails is effected.
