Definitions

  • the invention relates to a device for binding a boot to a gliding board.
  • a boot In the field of snow gliding sports, a boot is conventionally retained by two retaining elements, a front retaining element and a rear retaining element, which are fastened to the ski.
  • the patent document CH 687 589 proposes positioning a rod to connect the front and rear retaining elements.
  • the rod allows forces to be transmitted between the retaining elements, although a device of this type does not function optimally inasmuch as the connecting rod affects the free flexion of the ski.
  • the forces are transferred to an element positioned under the front and rear retaining elements, which generates force moments in the area of the retaining elements, which tends to tilt the front retaining element forward and the rear retaining element rearward.
  • the invention provides a device for binding a boot to a gliding board, which allows the drawbacks of the known devices of the prior art to be overcome.
  • the invention provides a device for binding a boot to a gliding board, which does not prevent the gliding board from bending/flexing freely.
  • the invention provides a gilding apparatus, which includes a gliding board equipped with a device for binding a boot to the gliding board, such device not preventing the gliding board from bending/flexing freely.
  • the invention provides a gliding apparatus equipped with a ski brake, a front retaining element, a rear retaining element, and an element that connects the front retaining element to the rear retaining element, to allow the forces to be recovered between them, and in which the force moments that are generated in the area of the retaining elements, which tend to tilt the front retaining element forward and the rear retaining element rearward, have reduced effects.
  • the invention provides for a binding device and a gliding apparatus according to the claims below.
  • the invention provides a device for binding a boot to a gliding board, such device including a front retaining element, a rear retaining element, an element for connecting the front retaining element to the rear retaining element, as well as a return spring exerting a force forcing the front retaining element and the rear retaining element toward one another.
  • the connecting element and the return spring are aligned, and the connecting element includes an articulation with respect to the front retaining element and/or the rear retaining element.
  • the invention also provides for a gliding apparatus including a gliding board equipped with a binding device, a first ski brake positioned on a first side of the gliding board, and a second ski brake positioned on the other side or the gliding board.
  • the invention provides a gliding apparatus including a gliding board equipped with a ski brake and a device for binding a boot to a gliding board that includes a front retaining element, a rear retaining element, an element for connecting the front retaining element to the rear retaining element, and a return spring exerting a force directed to cause the front retaining element and the rear retaining element to be moved toward one another.
  • the connecting element and the return spring are aligned, and the ski brake includes a first ski half-brake positioned on a first side of the gliding board and a second ski half-brake on the other side of the gliding board, so that a central channel is arranged between the first and the second half-brakes, within which the connecting element extends.
  • the connecting element is longitudinally affixed with respect to the front retaining element. It is also longitudinally affixed to the rear support element via the return spring. Consequently, the longitudinal component of the pressures that the boot exerts on the retaining elements is transmitted in the connecting element and does not pass through the gliding board.
  • the connecting element is rigid in tension and in compression, which results in successively ensuring a pulling effect when the ski flexes, and a pushing effect when the ski recovers its natural curvature.
  • the return spring is aligned with the connecting element. Consequently, during the flexing phases of the ski, the forces which are transmitted from the connecting element toward the rear retaining element do not cause the rear retaining element to tilt toward the rear, but instead, make it move in translation along the gliding element.
  • the front and rear articulations ensure a free rotation in the vertical plane of the connecting element with the front and rear retaining elements.
  • the support zones of the boot sole namely the heel piece and the two half-pedals of the brake, are arranged so that a central channel is provided in which the connecting element passes and is not vertically retained. This enables the connecting element to oscillate freely at the front as well as at the rear.
  • the connecting element is as close as possible to the boot sole.
  • the distance between the connecting element and the boot sole remains constant while the gliding board flexes, and this distance is optimized so as to be minimal. Because one knows that the distance between the connecting element and the boot is instrumental to the efficiency of the mechanism for recovering the tension forces, and that the greater this distance is, the greater pivoting phenomena of the retaining elements diminishes this efficiency, one understands the advantage of keeping the connecting element as close as possible to the boot, at all times, including while the gliding board flexes.
  • All the advantages of the invention are directed toward considerably improving the mechanism for recovering the forces of the binding during the “flexion-counterflexion” phases of the gliding board, during the bending of the ends of the ski downward and the bending of the ends of the ski upward.
  • FIG. 1 is a perspective view of a gliding apparatus according to the invention
  • FIG. 2 is a longitudinal side view of the gilding apparatus, in partial cross section;
  • FIG. 3 is a detailed perspective view of the first articulation
  • FIG. 4 is a detailed perspective view of the second articulation
  • FIG. 5 is a detailed perspective view of the brakes.
  • FIG. 1 shows a gliding apparatus 1 according to the invention.
  • the gliding apparatus 1 includes a gliding board 2 to which an interface 3 has been affixed.
  • the interface 3 includes a front portion and a rear portion.
  • a front retaining element 4 or toe piece, is assembled to the front portion of the interface.
  • a rear retaining element 5 or heel piece, is assembled to the rear portion of the interface.
  • Having an interface is non-limiting, as the invention can be implemented with an interface, or without an interface.
  • the ski brake 28 is arranged between the front retaining element 4 and the rear retaining element 5 and is composed of two half-brakes that function independently with respect to one another.
  • the connecting element 6 links the front retaining element 4 to the rear retaining element 5 and extends between the two half-brakes without hindering their functioning.
  • the connecting element 6 is rigid in tension and in compression.
  • FIG. 2 shows a longitudinal cross section of the gliding apparatus.
  • the front retaining element 4 includes a support plate 7 and a base 8 topped by a pivot 9 .
  • the body of the front retaining element 4 is pivotally mounted on the pivot 9 .
  • the construction of the front retaining element 4 is not described in greater detail here, inasmuch as the mechanism is already known and can be provided in an any number of forms known to those skilled in the art. That is, the front retaining element could be replaced, such as that illustrated, by any other front retaining element.
  • the rear retaining element 5 is also not described in detail here, inasmuch as it is a retaining element of the known heel construction type.
  • the rear retaining element 5 includes a return spring 23 , which presses the rear retaining element against the rear of the boot and, as a consequence, the front of the boot against the front retaining element 4 .
  • the connecting element 6 includes a front rod 10 , fastened to a first articulation, and a rear rod 11 .
  • the front rod 10 and the rear rod 11 are coaxially connected to one another via a threaded bushing 12 , or sleeve.
  • the threaded bushing allows the connecting element 6 to be adjusted in length. This entire connection has the particularity of being rigid in tension as well as in compression to prevent it from buckling during the bending of the gliding apparatus.
  • the rear rod 11 is retained in the heel spacer 13 of the rear retaining element 5 , and it can oscillate along a transverse axis.
  • the heel spacer 13 is positioned inside the sheet metal body 14 of the rear retaining element 5 .
  • FIG. 4 shows in detail the parts that comprise the second articulation 16 , which is arranged between the connecting element 6 and the rear retaining element 5 .
  • the various pieces are shown in exploded perspective.
  • the rear rod 11 is inserted in an eyelet 20 located at the base of the spacer 13 .
  • a piece which is the nose-spring support 21 , is slipped onto the rear rod 11 .
  • the nose-spring support 21 is directly in contact with the heel spacer 13 .
  • the nose-spring 22 and a return spring 23 are also slipped onto the rear rod 11 .
  • the nose-spring support 21 includes a groove 24 that passes through the center of the circular opening, which extends through it, and in which the rod is inserted.
  • the nose-spring 22 has an enlargement 25 , which complements the groove 24 .
  • the enlargement 25 and the groove 24 have common cylindrical surfaces that are capable of sliding with respect to one another, thus enabling the rear rod 11 to pivot with respect to the heel spacer 13 , that is, with respect to the rear retaining element 5 .
  • Maintaining the rear rod 11 in position in the eyelet 20 of the heel spacer 13 and adjusting and positioning one with respect to the other is carried out via a first support coupling 17 screwed onto the rear rod 11 in front of the eyelet 20 , a support washer 18 being intercalated between the first coupling 17 and the eyelet 20 , and via a second support coupling 19 screwed at the end of the rear rod so as to retain the return spring.
  • the second articulation comprises the eyelet 20 arranged in the heel spacer 14 , as well as the nose-spring support 21 and the nose-spring 22 , allow the rear rod 11 of the connecting element 6 to pivot with respect to the rear retaining element 5 .
  • the device is not limited to the particular illustrated example of a connection made by means of an eyelet arranged in the heel spacer, and can also be implemented with a pivot connection.
  • This pivot connection can be achieved with an axle extending through the spacer and the end of the rear rod.
  • the return spring 23 is slipped onto the connecting element 6 , the pressures that the boot exerts on the rear retaining element 5 , for example when the gilding board is flexed, are transmitted directly to the connecting element. No overhanging occurs, unlike when the return spring is positioned higher than the connecting element.
  • FIG. 3 shows, in detail, the parts that comprise the first articulation. They include a ball-and-socket joint that includes a ball part 26 having an outer spherical shape and positioned in a socket part 27 , having an inner cavity, the shape of which complements the ball part 26 .
  • the socket part 27 is threaded onto the end of the front rod 10 of the connecting element 6 .
  • the ball part 26 of the ball-and-socket joint includes a vertical bore through which a screw extends so that it can be connected to the front retaining element 4 .
  • the support plate 7 includes an upwardly open housing 29 for receiving the socket part 27 of the ball-and-socket joint, as well as a portion of the front rod 10 , which results in the front rod 10 being guided in an oscillating movement that remains in the longitudinal vertical plane of the gliding board.
  • a pivot connection can be made with an pin or axle extending through the support plate 7 and/or through the baseplate 8 and the end of the front rod 10 .
  • FIG. 5 shows the brake 28 in perspective, isolated from the remainder of the device.
  • the brake includes a plate 30 provided to rest on the interface 3 , and a heel support 31 , the upper surface of which is the boot sole is supported.
  • the heel support 31 includes, in its upper zone, two separate portions that constitute the two sides of a longitudinally oriented channel 32 .
  • This channel 32 is adapted to receive the rear rod 11 of the connecting element 6 and it has a height necessary to accommodate the dual flexion of the ski.
  • the brake 28 is characterized by a double mechanism of two half-brakes that are independent from one another.
  • Each of these half-brakes includes an arm 33 , at the end of which an end piece 34 is fastened.
  • the arm 33 is a metallic rod bent in two places at an angle of about 90° so as to define between these two bends a portion that is perpendicular to the rest of the rod. This perpendicular portion is kept in place between the heel piece 31 and the plate 30 . The two ends of the arm can thus be moved in rotation about the perpendicular portion.
  • the lower portion of the arm 33 i.e., the portion provided with an end piece 34 , penetrates the snow during the rotational movement of the arm.
  • the upper portion of the arm 33 is fixed within a half-pedal 35 .
  • the arm 33 is fixed within the half-pedal 35 by means of an additional bend of the upper end of the arm 33 along a direction that is parallel to the direction of the perpendicular portion.
  • the half-pedal 35 and the arm can move in rotation with respect to one another.
  • a link 36 connects the plate 30 to the half-pedal 35 .
  • the link 36 is rotatably mounted with respect to the plate 30 and to the half-pedal 35 so that at any time while the arm 33 moves, the link 36 , the half-pedal 35 , the arm 33 , and the plate 30 form a parallelogram.
  • the rotation of the link 36 with respect to the plate 30 is carried out between a lower position in which the link is substantially parallel to the plate 30 , and an upper position in which the link 36 forms a non-zero angle with the plate.
  • the link 36 is maintained in the upper position by the force of a brake spring 37 .
  • the second half-pedal is constructed the same as the first half-pedal 35 hereinabove described, but is symmetrical with respect to the vertical longitudinal plane of the gilding board.
  • the boot sole When the boot is in place, the boot sole rests on the two half-pedals 35 , and the weight of the boot sole thereon is sufficient to counteract the force of the spring, consequently bringing the links 36 and the half-pedals 35 to the lower position.
  • the brake spring 37 When the skier falls, causing the boot to be removed, the brake spring 37 immediately lifts the half-pedals 35 and frees the arms 33 as soon as the boot is released.
  • the passage for the connecting element 6 can be provided between the half-pedals. Consequently, the connecting element 6 can be positioned as close as possible to the boot sole, which improves the efficiency of the device for transmitting the forces between the front retaining element 4 and the rear retaining element 5 .
