Definitions

  • the present invention relates to a ski brake.
  • braking devices are often applied to skis and are in practice constituted by two arms which protrude laterally with respect to the ski and move to a level below the lower face of the ski, so as to provide an element for friction against the snow which prevents the ski from sliding freely when released from the ski boot.
  • a first type of brake has a so-called pedal arranged below the sole of the ski boot, generally in the heel region, and keeps the brake in retracted position, i.e. raised and generally to the side of the binding, so long as the skier's weight bears on it, and it is automatically extracted when the boot is separated from the ski.
  • the brake When in retracted position, the brake has to be arranged within the sides of the ski, and for this reason the brake arms oscillate about axes which are inclined with respect to the longitudinal extension, so as to obtain a lateral movement of the brake arms, as well as an oscillation or translatory motion which moves them below the lower face of the ski.
  • the aim of the invention is to eliminate the problems described above by providing a ski brake which allows to combine the compactness, typical of brakes connected to jaws, with the simplicity and elasticity of connection obtained by using a pedal connection.
  • a particular object of the invention is to provide a brake which may be integrated in the heel unit without however being functionally associated therewith.
  • the brake according to the invention can furthermore be connected to the heel unit, but in the sense that it is the braking device which performs possible actuations of the heel unit, not the heel unit which extracts the brake, as instead occurs in the solutions of the known art.
  • Another object of the present invention is to provide a brake which by virtue of its peculiar constructive characteristics is capable of giving the greatest assurances of reliability and safety in use.
  • a ski brake characterized in that it comprises an actuation means arranged on a ski in the region affected by the sole of a ski boot, said actuation means being connected to a slider, an elastic thrust means acting on said slider, said elastic thrust means being contrasted by the presence of the ski boot on the ski, said brake comprising arms and supports for said arms, said supports of the brake arms engaging said slider so as to generate, upon the translatory motion of said slider, a rotation of said arms about a first axis which is substantially horizontal and perpendicular to the longitudinal extension of the ski, each of said arms having a terminal portion which can rotate, in contrast with and by virtue of the action of a rotational elastic means, about a second axis which is substantially perpendicular to said first axis, an engagement means being furthermore provided on said terminal portion, said engagement means being suitable for interacting with a part which is rigidly associated with said ski for the rotation of said terminal portion about said second axis in a
  • the ski brake comprises actuation means arranged on the ski and comprising a pedal 10 which is articulated at an end of a lever 11.
  • lever 11 is articulated to a base 12 which can be fixed to the ski 13.
  • the end of a second lever 15 is articulated to the pedal 10, possibly in the same articulation position as the first lever 11 or in a point which is spaced therefrom.
  • the second lever is pivoted, at its other end, to a slider 20 which is slidingly guided on the base 12.
  • An elastic thrust means acts on the slider 20 and is constituted by a thrust spring 21 which acts between a first abutment 22 which is rigidly associated with the base 12 and a second abutment 23, which is arranged at the end of the slider 20.
  • the brake also comprises brake arm supports, designated by 30, which are articulated to a transverse shaft 31.
  • Shaft 31 is supported by side walls 32 which are rigidly associated with the base 12 or may be part of the heel unit.
  • a transverse actuation pivot 35 is connected to the supports 30 and is inserted in a recess 36 defined on the slider 20, so that the supports 30, one of which is arranged at each side, rotate about the transverse shaft 31 when the slider moves.
  • the brake arms extend from the supports 30 and are constituted by a coupling portion 41 which rigidly protrudes from the support 30 and extends substantially perpendicular to the direction of the transverse shaft 31 which constitutes the first articulation axis.
  • a terminal portion, indicated by 45, is connected to the coupling portion 41 and has a curved linking portion 46 provided with an insertion pin 47 which can be rotatably accommodated in a seat 48 defined on the coupling portion.
  • a rotational elastic means acts between the coupling portion and the curved linking portion and is constituted by a torsion spring 50 which is fixed at its ends to the coupling portion 41 and to the curved linking portion 46 respectively.
  • the curved linking portion 46 is connected, at its other end, to a straight portion 51 which ends with a protrusion 52.
  • An engagement means is provided at the curved linking portion 46, preferably proximate to the region of rotary articulation to the coupling portion 41 by means of the first pin 47 which defines a second rotation axis which is substantially perpendicular to said first axis.
  • the engagement means is constituted by an eccentric protrusion 55 which is suitable for interacting with a part which is rigidly associated with the ski 13.
  • the eccentric protrusion 55 is suitable for engaging a lateral curling 60 by contact.
  • Lateral curling 60 is rigidly associated with the base 12, so that when the brake arms rotate about the first axis and move toward the extracted position, the engagement between the eccentric protrusions 55 and the lateral curls 60 causes a rotation of substantially 90° about the second axis which in practice extracts the brake arms laterally.
  • a first portion of rotation of the support 30 about the first axis 31 begins during this initial step, and the eccentric protrusion 55, by engaging the curlings 60, produces an outward rotation of the terminal portions, loading the torsion springs 50.
  • the terminal portions in extracted position, remain rotated outward by virtue of the continuing engagement of the eccentric protrusion 55 with the curling 60.
  • the brake is structured to be easily coupled to a heel unit without being functionally connected thereto, or it is also possible, as illustrated in a copending application in the name of the same Applicant, to provide a functional connection between the brake and the heel unit in which however it is the brake pedal which actuates functions of the heel element, such as for example automatic reset.
  • ski brake thus conceived is susceptible to numerous modifications and variations, all of which are within the scope of the inventive concept.
  • the materials employed, as well as the contingent shapes and dimensions may be any according to the requirements.
