Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
244 words
The combination comprising a ski, a base member for supporting a ski boot, means for securing a ski boot to said base member and a binding for connecting said base member to said ski, said binding comprising: a. an elongated passage in said base member extending between opposite sides thereof, b. a piston slidable in said passage, c. stop means preventing said piston from sliding out one end of said passage, d. a pin having a frusto-conical surface normally extending from said one end of said passage, e. means adjustably mounting said pin on said piston such that the axial distance between said frusto-conical surface on said pin and said piston may be varied, f. a plug removably secured in the end of said passage member opposite said one end, said plug having a frusto-conical surface extending radially from said opposite end of said passage, g. a plurality of conical spring washers arranged within said passage and extending between said plug and said piston biasing said piston towards said stop means, and h. fitting means arranged on said ski including a pair of spaced conical recesses therein for receiving said conical surfaces of said pin and plug, i. whereby the axial distance between said frusto-conical surface of said pin and plug may be changed by adjusting said pin mounting means and the biasing pressure applied to said piston may be changed by removing said plug and rearranging said spring washers relative to each other.
Claim 2
Dependent Claim
244 words
The combination comprising a ski, a base member for supporting a ski boot, means for securing a ski boot to said base member and a binding for connecting said base member to said ski, said binding comprising: a. an elongated passage in said base member extending between opposite sides thereof, b. a piston slidable in said passage, c. stop means preventing said piston from sliding out one end of said passage, d. a pin having a frusto-conical surface normally extending from said one end of said passage, e. means adjustably mounting said pin on said piston such that the axial distance between said frusto-conical surface on said pin and said piston may be varied, f. a plug removably secured in the end of said passage member opposite said one end, said plug having a frusto-conical surface extending radially from said opposite end of said passage, g. a plurality of conical spring washers arranged within said passage and extending between said plug and said piston biasing said piston towards said stop means, and h. fitting means arranged on said ski including a pair of spaced conical recesses therein for receiving said conical surfaces of said pin and plug, i. whereby the axial distance between said frusto-conical surface of said pin and plug may be changed by adjusting said pin mounting means and the biasing pressure applied to said piston may be changed by removing said plug and rearranging said spring washers relative to each other.
Claim 3
Dependent Claim
244 words
The combination comprising a ski, a base member for supporting a ski boot, means for securing a ski boot to said base member and a binding for connecting said base member to said ski, said binding comprising: a. an elongated passage in said base member extending between opposite sides thereof, b. a piston slidable in said passage, c. stop means preventing said piston from sliding out one end of said passage, d. a pin having a frusto-conical surface normally extending from said one end of said passage, e. means adjustably mounting said pin on said piston such that the axial distance between said frusto-conical surface on said pin and said piston may be varied, f. a plug removably secured in the end of said passage member opposite said one end, said plug having a frusto-conical surface extending radially from said opposite end of said passage, g. a plurality of conical spring washers arranged within said passage and extending between said plug and said piston biasing said piston towards said stop means, and h. fitting means arranged on said ski including a pair of spaced conical recesses therein for receiving said conical surfaces of said pin and plug, i. whereby the axial distance between said frusto-conical surface of said pin and plug may be changed by adjusting said pin mounting means and the biasing pressure applied to said piston may be changed by removing said plug and rearranging said spring washers relative to each other.
Claim 4
Dependent Claim
244 words
The combination comprising a ski, a base member for supporting a ski boot, means for securing a ski boot to said base member and a binding for connecting said base member to said ski, said binding comprising: a. an elongated passage in said base member extending between opposite sides thereof, b. a piston slidable in said passage, c. stop means preventing said piston from sliding out one end of said passage, d. a pin having a frusto-conical surface normally extending from said one end of said passage, e. means adjustably mounting said pin on said piston such that the axial distance between said frusto-conical surface on said pin and said piston may be varied, f. a plug removably secured in the end of said passage member opposite said one end, said plug having a frusto-conical surface extending radially from said opposite end of said passage, g. a plurality of conical spring washers arranged within said passage and extending between said plug and said piston biasing said piston towards said stop means, and h. fitting means arranged on said ski including a pair of spaced conical recesses therein for receiving said conical surfaces of said pin and plug, i. whereby the axial distance between said frusto-conical surface of said pin and plug may be changed by adjusting said pin mounting means and the biasing pressure applied to said piston may be changed by removing said plug and rearranging said spring washers relative to each other.
Claim 5
Dependent Claim
40 words
The combination of claim 1 wherein said means adjustably mounting said pin on said piston comprise an externally threaded shaft on one of said pin and piston and an externally threaded bore on the other of said pin and piston.
Claim 6
Dependent Claim
43 words
The combination as defined in claim 2 wherein at least a portion of said spring washers is arranged in pairs, the concave surfaces of each pair facing each other, and the convex faces of adjacent washers, one from each pair, facing each other.
Claim 7
Dependent Claim
43 words
The combination as defined in claim 3 wherein a further portion of said spring washers is arranged with the convex face of one washer contiguous to the concave face of an adjacent washer whereby the bias pressure applied to said piston is increased.
Claim 8
Dependent Claim
60 words
The combination as defined in claim 4 wherein said fitting means comprises a pair of latching jaws, one of said latching jaws being pivotally mounted, one of said spaced conical recesses being located in each of said latching jaws, and cam means including a lever arranged to abut against said pivotal jaw for selectively retaining said jaw in engaging position.
Claim 9
Dependent Claim
30 words
The combination as defined in claim 5 wherein said fitting means comprises a U-shaped member secured to the upper part of said ski, said U-shaped member including said latching jaw.
Claim 10
Dependent Claim
