Abstract
Abstract An toy track coupling mechanism has guidance channels to aid alignment formed on confronting ends of the track sections. A horizontally operating latch prevents unwanted disconnection of the coupled track sections during assembly and play. A laterally adjacent horizontally operating release switch allows easy disassembly of the track sections by disengaging the latch in response to natural hand pressures and movements.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
124 words
An interlocking toy vehicle track comprising adjacent track sections having opposing ends and opposing sides, each of the track sections having: a coupling mechanism at the ends of the track section for coupling adjacent track sections to each other, the coupling mechanism comprising a male locking portion and a female locking portion, the male locking portion having a body abutment extending outwardly from the opposing ends of the track section, and an elongated, resilient hook member extending outwardly from the body abutment; the sides of the track sections having flexible portions, the flexible portions of one track section being located adjacent to the hook members of the adjacent track sections and operatively associated with the hook members when the adjacent track sections are interlocked.
Claim 2
Dependent Claim
124 words
An interlocking toy vehicle track comprising adjacent track sections having opposing ends and opposing sides, each of the track sections having: a coupling mechanism at the ends of the track section for coupling adjacent track sections to each other, the coupling mechanism comprising a male locking portion and a female locking portion, the male locking portion having a body abutment extending outwardly from the opposing ends of the track section, and an elongated, resilient hook member extending outwardly from the body abutment; the sides of the track sections having flexible portions, the flexible portions of one track section being located adjacent to the hook members of the adjacent track sections and operatively associated with the hook members when the adjacent track sections are interlocked.
Claim 3
Dependent Claim
51 words
The interlocking toy vehicle track of claim 1 wherein the flexible portions of the sides of the track sections further include release pins on inner surfaces of the flexible portions, the release pins disposed between the flexible portions of the track section and the hook members of the adjacent track sections.
Claim 4
Dependent Claim
38 words
The interlocking toy vehicle track of claim 1, wherein the track sections include projection pins extending outwardly from the body abutments and laterally adjacent to the elongated hook members to limit lateral flexion of the elongated hook member.
Claim 5
Dependent Claim
36 words
The interlocking toy vehicle track of claim 3, wherein the track sections include side projections located at the sides of the track sections, the side projections extending outwardly from the opposing ends of the track section.
Claim 6
Dependent Claim
68 words
The interlocking toy vehicle track of claim 4, wherein said female locking portion of said coupling mechanism comprises: a) a notch recessed inwardly from the ends of the track section adapted to receive the hook member and the projection pin of the adjacent sections; and b) a side receptacle located at the sides of the track section adapted to receive the side projection of the adjacent track sections.
Claim 7
Dependent Claim
32 words
The interlocking toy vehicle track of claim 5, wherein the coupling mechanism includes keepers located adjacent the notch, the keepers-having distal edges against which the hook members of adjacent track sections lock.
