Abstract
Abstract A cross-country skiing path has a pair of side-by-side elongated tracks each formed as an upwardly open and longitudinally extending channel in turn each formed of a longitudinal succession of separate track elements that each have a separate web and inside and outside flanges flanking this web. Each inside flange of each element of each row is turned toward an inside flange of a corresponding element of the other row and is provided with an ear extending toward the other row and having a longitudinal length equal to approximately half the overall longitudinal length of the element. Each ear is longitudinally offset from the corresponding ear of the corresponding element of the other row and extends transversely beyond the longitudinal midline of the path. An elongated longitudinally extending connector member, such as a cable, passes through the ears at the midline and interconnects the elements into a chain. Similar connecting members extend through the outside flanges.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
171 words
A ski path comprising: a pair of side-by-side rows of elongated tracks each formed as an upwardly open and longitudinally extending channel in turn each formed of a longitudinal succession of separate similar track elements each having a central web and inside and outside flanges upstandingly higher than and flanking said web, each inside flange of each element of each row being turned toward an inside flange of a corresponding element of the other row and being provided with an ear extending toward said other row and having a longitudinal length shorter than the overall longitudinal length of the element, each ear being longitudinally offset from the corresponding ear of the corresponding element of the other row and extending transversely beyond a longitudinal midline of said path extending generally between said rows; and an elongated longitudinally extending connector member passing through said ears at said midline and interconnecting said corresponding elements in side-by-side relation into a chain with the upstanding flanges and webs of each side forming one of said channels.
Claim 2
Dependent Claim

A ski path comprising: a pair of side-by-side rows of elongated tracks each formed as an upwardly open and longitudinally extending channel in turn each formed of a longitudinal succession of separate similar track elements each having a central web and inside and outside flanges upstandingly higher than and flanking said web, each inside flange of each element of each row being turned toward an inside flange of a corresponding element of the other row and being provided with an ear extending toward said other row and having a longitudinal length shorter than the overall longitudinal length of the element, each ear being longitudinally offset from the corresponding ear of the corresponding element of the other row and extending transversely beyond a longitudinal midline of said path extending generally between said rows; and an elongated longitudinally extending connector member passing through said ears at said midline and interconnecting said corresponding elements in side-by-side relation into a chain with the upstanding flanges and webs of each side forming one of said channels.
Claim 3
Dependent Claim
27 words
The path defined in claim 1 wherein each ear has a longitudinal length equal to no more than half of the longitudinal length of the respective element.
Claim 4
Dependent Claim
25 words
The path defined in claim 2 wherein each ear has a longitudinal length substantially equal to half of the longitudinal length of the respective element.
Claim 5
Dependent Claim
25 words
The path defined in claim 3, further comprising a pair of outer connector members each passing longitudinally through the outer flanges of a respective row.
Claim 6
Dependent Claim
27 words
The path defined in claim 4, further comprising a plurality of spacers each between two neighboring elements and abutting same to maintain a minimum longitudinal spacing therebetween.
Claim 7
Dependent Claim
19 words
The path defined in claim 5, wherein said spacers are carried on at least one of said connector members.
Claim 8
Dependent Claim
18 words
The path defined in claim 6, wherein said one member is the first-mentioned member extending through said ears.
Claim 9
Dependent Claim
18 words
The path defined in claim 6, wherein said spacers are tubes, said one member passing through said tubes.
Claim 10
Dependent Claim
27 words
The path defined in claim 8, wherein said elements each have a longitudinal length equal to between one-quarter and one-third of the transverse length of said elements.
Claim 11
Dependent Claim
26 words
The path defined in claim 1 wherein said elements are each formed at the upper portion of said web with an array of longitudinally extending ridges.
