Abstract
Abstract A ski brake, which is equipped with at least one brake arm, a foot element and a spring-loaded articulated lever system arranged between the brake arm and the foot element, has a sliding crank as the articulated lever system. The crank is connected with the brake arm and the coupler forms the foot element. A sliding element is arranged spring-loaded in a housing. Joints between the foot element and the sliding element can be arranged at different levels relative to the surface of the ski. If two brake arms are used, they are connected with each other by way of a U-shaped intermediate zone.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
89 words
A ski brake comprising: A. at least one brake arm, and B. a spring loaded, articulated lever system including: i. a crank that is connected to said brake arm by a first joint, ii. a coupler that presents a foot element and that is joined to the crank by a second joint, and iii. a sliding element that is arranged to be spring-loaded in a housing, a portion of the sliding element extending from an end of the housing and being connected to the coupler by a third joint.
Claim 2
Dependent Claim
89 words
A ski brake comprising: A. at least one brake arm, and B. a spring loaded, articulated lever system including: i. a crank that is connected to said brake arm by a first joint, ii. a coupler that presents a foot element and that is joined to the crank by a second joint, and iii. a sliding element that is arranged to be spring-loaded in a housing, a portion of the sliding element extending from an end of the housing and being connected to the coupler by a third joint.
Claim 3
Dependent Claim
50 words
The ski brake as claimed in claim 1 in which the ski brake has a length adapted to be arranged substantially parallel with the length of a ski, the first joint being arranged stationary on the housing and the third joint being movable along the length of the ski brake.
Claim 4
Dependent Claim
50 words
The ski brake as claimed in claim 2 in which the ski brake presents a bottom-side surface adapted to be installed on the planar, top-side surface of said ski and the first and third joints are arranged at different levels above said bottomside surface to form an eccentric sliding crank.
Claim 5
Dependent Claim
27 words
The ski brake as claimed in claim 3 in which the first joint is closer to the bottom-side surface of the ski brake than the third joint.
Claim 6
Dependent Claim
79 words
The ski brake as claimed in claims 1, 2, 3 or 4 in which there are two brake arms and two cranks connected together by a U-shaped, intermediate portion forming a portion of the second joint, and the sliding element comprising two angular parts each having a longer portion and a shorter portion, the longer portions each being engaged with a spring in said housing and the shorter portions extending from said housing forming portions of the third joint.
Claim 7
Dependent Claim
49 words
The ski brake as claimed in claim 5 in which the housing presents two walls through which the shorter portions extend, the end of each longer portion opposite its shorter portion having a flange and the springs being carried by the longer portions between the flanges and the walls.
Claim 8
Dependent Claim
18 words
The ski brake as claimed in claim 6 in which the springs are arranged encapsulated in the housing.
Claim 9
Dependent Claim
48 words
The ski brake as claimed in claim 5 in which the coupler is formed of two parallel foot bars, each being connected at one end to the U-shaped, intermediate portion of the cranks and at the other end to one of the shorter portions of the angular parts.
Claim 10
Dependent Claim
49 words
The ski brake as claimed in claim 5 in which the coupler is formed of a foot plate provided with a center opening and is connected along one edge with the U-shaped, intermediate portion of the cranks and along another edge with the shorter portions of the angular parts.
Claim 11
Dependent Claim
27 words
The ski brake as claimed in claim 5 in which the cranks are bent to form a portion tangential to an arc drawn around the third joint.
Claim 12
Dependent Claim
72 words
The ski brake as claimed in claim 1 in which a ski is provided with mounting means for detachably mounting the ski brake on the ski, the mounting means including a centering crosspiece mating with structure carried on a ski for arranging the ski brake on the ski and a leaf spring and detent combination operating together with additional structure on the ski to detachably lock the ski brake on the ski.
