Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
200 words
A cavity-sole ski boot and mating ski-attachable block comprising: a. a ski boot; b. a sole with a central longitudinal cavity attached to said ski boot; c. a block mating with said cavity and attachable to a ski, said block comprising: 1. a central rectangular portion; 2. a longitudinally extending forward end having left and right sides and a blunt termination; 3. a longitudinally extending after end having left and right sides and a rear blunt termination; 4. two vertical half-round grooves proximate the juncture of said central rectangular portion with each of said forward end and said after end, one groove being on the left side and one on the right side of the respective end; and 5. a longitudinal half-round groove along each of the left and right sides of each of said forward end and said after end, each groove containing a detent stop; d. four detents, two of which are located near the forward end of said sole and operate laterally into said cavity and two of which are located toward the after end of said sole and operate laterally into said cavity, whereby said ski boot may be locked to said block by detent action.
Claim 2
Dependent Claim
200 words
A cavity-sole ski boot and mating ski-attachable block comprising: a. a ski boot; b. a sole with a central longitudinal cavity attached to said ski boot; c. a block mating with said cavity and attachable to a ski, said block comprising: 1. a central rectangular portion; 2. a longitudinally extending forward end having left and right sides and a blunt termination; 3. a longitudinally extending after end having left and right sides and a rear blunt termination; 4. two vertical half-round grooves proximate the juncture of said central rectangular portion with each of said forward end and said after end, one groove being on the left side and one on the right side of the respective end; and 5. a longitudinal half-round groove along each of the left and right sides of each of said forward end and said after end, each groove containing a detent stop; d. four detents, two of which are located near the forward end of said sole and operate laterally into said cavity and two of which are located toward the after end of said sole and operate laterally into said cavity, whereby said ski boot may be locked to said block by detent action.
Claim 3
Dependent Claim
33 words
A cavity-sole ski boot according to claim 1 wherein said cavity is in the range of 15 to 20 cm long and said block is 1/2 to 11/2 cm shorter than said cavity.
Claim 4
Dependent Claim
59 words
A cavity-sole boot according to claim 2 wherein said detents are located so that when the detents toward the rear end of the sole are adjacent said rear blunt termination, the detents at the forward end of said sole are adjacent said two vertical half round grooves proximate the junction of said central rectangular portion with said forward end.
Claim 5
Dependent Claim
33 words
A cavity-sole ski boot according to claim 1 wherein said detents include set screws threaded into said sole and bearing against the springs of said spring-loaded detents in order to adjust spring tension.
Claim 6
Dependent Claim
42 words
A cavity-sole ski boot according to claim 1 wherein the two detents at one end of said sole are at least one cm closer to the end of said cavity than are the two detents at the opposite end of said sole.
Claim 7
Dependent Claim
130 words
In skiing apparatus comprising a ski boot having a sole cavity, a ski, a block attached to the top of said ski and mating with said cavity, the combination for securing said boot to said ski comprising: a. a first pair of detents entering said cavity laterally at the forward portion of said boot; b. a second pair of detents entering said cavity laterally at the rear portion of said boot; c. grooves in said block for vertical entry and fore-and-aft locking movement of said first and second pair of detents; and, d. a levering device secured to said ski and operative to bear against said boot so as to move said boot in a fore-and-aft direction relative to said ski in order to move said detents into detent stops.
Claim 8
Dependent Claim
130 words
In skiing apparatus comprising a ski boot having a sole cavity, a ski, a block attached to the top of said ski and mating with said cavity, the combination for securing said boot to said ski comprising: a. a first pair of detents entering said cavity laterally at the forward portion of said boot; b. a second pair of detents entering said cavity laterally at the rear portion of said boot; c. grooves in said block for vertical entry and fore-and-aft locking movement of said first and second pair of detents; and, d. a levering device secured to said ski and operative to bear against said boot so as to move said boot in a fore-and-aft direction relative to said ski in order to move said detents into detent stops.
Claim 9
Dependent Claim
38 words
In skiing apparatus according to claim 6 the combination in which said levering device is secured to said ski behind said boot and is operable by a lever arm to force said boot forward relative to said ski.
Claim 10
Dependent Claim
24 words
In skiing apparatus according to claim 7 the combination in which said lever arm terminates in a closed loop for securing a retaining strap.
Claim 11
Dependent Claim
