Portable seat

Claim 2

A portable seat for securement between the upper ends of two ski poles having their respective longitudinal axes crossing at a predetermined intersecting point to transfer and distribute the load of a person sitting on the seat substantially along the longitudinal axes of the ski poles, said intersecting point being located below said seat, said portable seat comprising a sheet of flexible material, a tube retained in each end edge of said sheet, each said end edge having a loop formed therein by overlapping and securing said sheet material, each said tube maintaining said sheet extended width-wise when a load is applied on said sheet and permitting said seat to be folded upon itself for storage in a clothing pocket, a cord like member passing through each tube and extending from opposed ends thereof and connectable to the upper end of a respective one of said two ski poles and depending therefrom to said tube that it is connected to whereby to maintain said sheet extended lengthwise between said two ski poles, said cord like member extending a predetermined distance from its associated tube to its attachment point on said upper end of said ski pole.

Claim 3

A portable seat as claimed in claim 1 wherein said cord like member is provided with an end connector formed as a sliding loop at the free end of said cord.

Claim 4

A portable seat as claimed in claim 1 wherein said end connector is a cup member secured at the free end of said cord.

Claim 5

A portable seat as claimed in claim 1 wherein said cord like member is an elongated cord passing through a respective one of said tubes and secured at both ends to form a knot, a bushing secured in a respective end of each said tubes, said knot being positioned within said tube and slidingly retained therein between said two bushings whereby said seat can be adjusted, after said cord is secured between said ski poles.

Claim 6

A portable seat as claimed in claim 4 wherein said bushing is provided with a circumferential flange extending above the outer surface of said tube to prevent said loop of said flexible material from sliding off said tube located in said loop.

Claim 7

A portable seat structure as claimed in claim 1 wherein said intersecting point is determined by a chart having a scale thereon indicating the location of said intersection point in relation to the length of said ski pole.

Claim 8

A portable seat structure as claimed in claim 6 wherein said chart is aligned with a basket provided on the lower end of the ski pole, said scale having a gradient for ski poles in the range of from 44 to 58 inches, each inch marking in said range being spaced one inch apart with said 44 inch marking located approximately 9 1/2 inches from the upper edge of said basket.

Claim 9

A portable seat structure comprising a seat formed from a sheet of flexible material, said seat comprising a sheet of flexible material, an elongated cylindrical tube retained in each end edge of said sheet, each said end edge having a loop formed therein by overlapping and securing said sheet material, said cylindrical member maintaining said sheet extended widThwise when a load is applied on said sheet and permitting said seat to be folded upon itself for storage in a clothing pocket, an elongated cord passing through a respective one of said tubes and secured at both ends to form a knot, a bushing secured in a respective end of each said tubes, said knot being positioned within said tube and slidingly retained therein between said two bushings whereby said seat can be adjusted, said cord being connectable between the upper end of a respective one of said two ski poles and depending therefrom to maintain said sheet extended lengthwise between said two ski poles, said cord extending a predetermined distance from a respective one of said end edges to its attachment point on said upper end of said two ski poles, said two ski poles intersecting each other at an intersection point below said seat so that said support members are spaced apart at their upper ends and lower ends whereby the load on the seat is distributed downwardly along the longitudinal axis of the ski poles.

Claim 10

A portable seat structure comprising a seat formed from a sheet of flexible material, said seat comprising a sheet of flexible material, an elongated cylindrical tube retained in each end edge of said sheet, each said end edge having a loop formed therein by overlapping and securing said sheet material, said cylindrical member maintaining said sheet extended widThwise when a load is applied on said sheet and permitting said seat to be folded upon itself for storage in a clothing pocket, an elongated cord passing through a respective one of said tubes and secured at both ends to form a knot, a bushing secured in a respective end of each said tubes, said knot being positioned within said tube and slidingly retained therein between said two bushings whereby said seat can be adjusted, said cord being connectable between the upper end of a respective one of said two ski poles and depending therefrom to maintain said sheet extended lengthwise between said two ski poles, said cord extending a predetermined distance from a respective one of said end edges to its attachment point on said upper end of said two ski poles, said two ski poles intersecting each other at an intersection point below said seat so that said support members are spaced apart at their upper ends and lower ends whereby the load on the seat is distributed downwardly along the longitudinal axis of the ski poles.

Claim 11

A portable seat as claimed in claim 8 wherein said poles are attached together at said intersection point by a strap-like attachment means.

Claim 12

A portable seat structure as claimed in claim 9 wherein each said cord terminates in a free end connector for attachment to the upper end of the ski pole.

Claim 13

A portable seat as claimed in claim 8 wherein said bushing is provided with a circumferential flange extending above the outer surface of said tube to prevent said loop of said flexible material from sliding off said tube located in said loop.
