Definitions

  • the invention relates to a device for attaching a boot to a gliding board, particularly adapted to ski boot safety bindings, that is to say devices intended to securely hold a boot on a ski by exerting pressure on a ski boot. the heel of the shoe and pressing it forward against a front attachment device, ensuring an automatic release of the shoe in case of fall of the skier. It also relates to a ski on which is fixed such a device and a method of assembly and disassembly of such a device, used for its manufacture and maintenance.
  • a ski boot binding device is for example described in the patent FR2765115 . It comprises a heel piece, illustrated in FIG. 1, composed mainly of a tubular cylindrical body 1 forming a heel catch 1a in its lower part. This body 1 is articulated around a cam 2 forming part of a U-shaped stirrup, not shown, whose arms are articulated around a horizontal axis on a base mounted on a ski.
  • the body 1 contains a helical spring 3, working in compression between a piston 4, bearing on the cam 2, and a stop 5 in the form of a nut mounted on a screw 6 provided with a collar 6a by which the screw 6 'presses a rim 1b of the body 1, forming a bearing surface.
  • the rim 1b surrounds an upper opening 7 of the body 1 in which the screw 6 is accessible to adjust the hardness of the heel.
  • the rotation of the screw causes the longitudinal displacement of the stop nut 5 and the modification of the compression of the spring 3.
  • the cylindrical body 1 is surrounded by a casing 9 of transparent synthetic material for decoration.
  • the assembly of the elements contained in the body 1 is done by its lower opening 8 located on the side of the heel grip 1a, according to a method called "mounting from below”. First introduced the screw 6 provided with the nut 5, then the spring 3 and the piston 4. After compression of the piston, is then put in place the cam 2 and then fixed the arms of the stirrup at the ends of the cam.
  • the spring 3 can then be compressed by rotating the screw 6.
  • the body 1 implements the release function, which allows to release the back of the shoe in case of significant effort as is the case in a skier's fall forward.
  • a disadvantage of this device is the complexity of its mounting from below, which causes a high manufacturing cost and complicates the maintenance of the device since the disassembly is also complex.
  • the document FR2263796 has a similar heel but "mounted from the top", that is to say whose elements are introduced into a tubular body by its upper opening, opposite to the heel gripper.
  • the adjusting screw is held in position within the device by its thread with a cooperating element, which is integral with the tubular body, or by the tubular body itself.
  • the disadvantage of such a device is that the adjustment of the hardness of the spring is accompanied by the movement of the screw.
  • the screw is inserted into the tubular body, its accessibility with a screwdriver becomes difficult and delicate and the solution lacks a lot of usability.
  • a second disadvantage is its lack of security. Indeed, the spring is strongly compressed and exerts a significant thrust on the adjusting screw. If the thread of this screw gives way, after wear for example, the screw can be violently thrown outwards, risking injury to a skier or causing material damage.
  • the object of the present invention is to provide a shoe attachment device on a gliding board does not have the disadvantages of the prior art mentioned above.
  • a first object of the invention is to provide a fixing device whose adjustment is easy and user-friendly.
  • a second object of the invention is to provide a fixing device whose mounting and maintenance are easy.
  • a third object of the invention is to provide a secure fastening device.
  • the invention responds to the first two objects by proposing a fixing device whose assembly is done by an opening of a body located at the opposite end to the jaw, and whose adjustment is done by an intermediate element fixed longitudinally and always easily accessible.
  • the invention responds to the third object by a locking means of the end opposite the jaw to prevent the ejection of elements of the device through the outer opening under the force of the compressed spring.
  • the invention consists of a shoe attachment device on a gliding board, comprising a jaw, a body in which is mounted a spring bearing on a stop whose position is adjustable by a screw comprising a screw thread , this stop being placed towards one end of the body comprising an external opening located opposite the jaw and of sufficient size to receive the spring, the stop and the screw, characterized in that the screw moves in the longitudinal direction in the body and cooperates with a driving member, rotatable relative to the body so that its rotation causes rotation and longitudinal displacement of the screw.
  • the drive element may be disposed at the outer opening of the tubular body, be fixed longitudinally and held by two outer and inner holding members.
  • the screw may comprise a screw thread on its outer surface cooperating with a screw thread of the inner surface of the body, and a central opening on its outwardly facing surface in which is located a rod of corresponding format of the means of training.
  • the central opening can be in the shape of a polygon.
  • the drive means may comprise an opening on its outer face allowing it to be rotated with a standard tool, and may have a collar bearing on the holding elements.
  • the means for holding the driving element can be achieved by at least one screw passing through the body between the opening of the body and the screw.
  • the external holding means of the driving element can be realized by a removable cap disposed on the body at its opening and having an opening allowing access to the driving element with the aid of a tool for its rotation.
  • the inner holding member may comprise two screws passing through the cover and the body, these two screws having the second function of fixing the cover on the body.
  • the shoe attachment device may comprise a means for blocking the outer opening of the body to prevent the accidental ejection of elements of the device under the effect of the spring.
  • This locking means can be achieved by at least one of the holding means of the drive element. It can be achieved by two screws through the body whose spacing is greater than the central opening of the screw and the rod of the drive means to allow its passage and rotation and whose spacing is less than the diameter of the screw for making a means of blocking the opening.
  • the stop may be distinct from the screw, be made of plastic material of the polyamide type and has a long length to cooperate with the axis of the piston and maintain it on the longitudinal axis of the tubular body.
  • the shoe attachment device as described above may be a ski boot attachment heel whose body is a tubular body and comprises an end in connection with a jaw comprising a cam on which a piston rests under the action of the spring , the screw and the drive means being placed towards the outer opening of the tubular body opposite the jaw.
  • the invention also relates to a ski-type gliding board comprising a boot attachment device as described above.
  • the invention also relates to a method of assembly / disassembly of such a shoe attachment device comprising the step of mounting or dismounting a driving element, its inner and outer holding means, a screw comprising a screw thread, a spring and a stop in a body of the device by an outer opening of this body.
  • Figures 2 to 5 illustrate an embodiment of the invention applied to a ski boot attachment heel.
  • This heel comprises a tubular body 11 having a first zone called “attachment zone” because it is connected to a jaw 11a to cooperate with the rear heel of a ski boot, this zone ending in an end 18 facing the shoe, and a second zone called “outer zone”, because oriented opposite the jaw 11a towards the outside of the device, ending in an outer end 17.
  • a cam 12, rotatable about an axis 19 connected to two lateral arms 20 mounted on a base of the binding placed on a ski is disposed in the fastening zone of the tubular body 11.
  • This tubular body further comprises various elements mounted by its outer end 17, in the following order: a piston 14 resting on a flat portion formed within the generally cylindrical cam 12, a compression spring 13 bearing on the piston 14 , a stop 15 resting on the spring 13, a screw 16 comprising a lateral screw thread 16a cooperating with a thread of the inner surface of the tubular body 11, the screw 16 bearing on the abutment 15.
  • the abutment 15 is polyamide, which has the advantage of providing contact with the spring 13 mechanically less sensitive to friction and wear that a direct contact of the spring with the metal screw 16 for example.
  • the stop 15 has a tubular elongated portion extending centrally of the coil spring 13 and cooperating with a piston rod 14, in order to maintain the latter on the longitudinal axis of the body 11.
  • a drive element 26, comprising an elongated and square portion 26b, oriented towards the attachment zone of the device, cooperating with the external central opening 16b of the screw 16, a collar 26a and an outer opening 26c of hexagonal shape allowing its rotating by a standard tool, located on the side of the outer opening 17 of the body 11, is disposed at this outer end 17 of the tubular body 11 so as to be easily accessible with a tool from the outside.
  • the elongated portion 26b of the drive member may have any other polygonal shape.
  • its outer opening 26c can have any other form allowing it to be actuated with a tool, such as a screwdriver for example.
  • the driving element 26 is held in this position at the outer end 17 of the tubular body 11 by a first external holding means, in the form of a cover 21 disposed around the outer zone of the tubular body 11 and by a second internal holding means, in the form of two screws 22 which pass through apertures facing each other 23 and 24 respectively of the cover 21 and the tubular body 11 and are placed between the end 18 of the fastening zone of the tubular body 11 which is connected to the jaw 11a and the drive element 26.
  • Its flange 26a rests on these screws 22, allowing the passage and rotation of its elongate and square portion 26b cooperating with the central square connection opening 16b of the screw 16.
  • This assembly thus maintains the driving element 26 by prohibiting any longitudinal movement in the tubular body 11 but allowing its rotation and its cooperation with the adjusting screw 16.
  • the screws 22 also fulfill two additional functions. First, they pass through the tubular body 11 above the screw 16 and their spacing is smaller than the diameter of the screw so that they serve as an external stop to the screw 16 in case of displacement of the latter towards the outer end 17 and thus fulfill a function of blocking means of the outer opening 17 of the tubular body 11 preventing the possible ejection of the screw 16 and other elements of the binding under the force of the spring 13 in case of breakage of the no screws 16a. Then, the screws 22 serve as fixing means of the cover 21 on the tubular body 11.
  • the outer portion 31 of the hood comprises a spoon support member 29 and a spoon 30, placed in a suitable housing.
  • the spoon 30 can receive the support of the end of a ski pole for actuating the binding.
  • the outer portion 31 of the cover further has a small opening which allows the passage of a hexagonal key type tool, cooperating with the outer opening 26c of the drive member 26 to put it in motion. This opening is small enough to ensure the retention of the elements 26, 29 and 30 in the outer zone of the device while representing a second means of blocking the outer opening of the device to prevent any ejection of elements, such as the screw 16 which the diameter is greater than that of this opening 31.
  • the cover 21 also fulfills a safety function.
  • the adjustment of the triggering threshold of the attachment is achieved by the rotation of the drive element 26.
  • This rotation causes the rotation of the screw 16 through the connection between the male and female parts respectively 26b and 16b respectively elements 26 and 16, this rotation causing the longitudinal displacement of the screw 16 by the screw thread 16a, ie its displacement along the central axis of the tubular body 11, and the simultaneous movement the abutment 15, inducing the increase or reduction of the compression of the spring 13 and consequently the force transmitted on the cam 12 by the piston 14.
  • FIG. 3 illustrates the slightly compressed spring 13, the screw 16 and the stop 15 being in their furthest position from the cam 12.
  • FIG. 4 illustrates the spring 13 in a highly compressed configuration, the screw 16 being being in abutment in its extreme tightening position.
  • the driving element 26 is driven only by a rotational movement and does not move longitudinally: it occupies the same longitudinal position in FIGS. 3 and 4.
  • the invention has been illustrated in the specific context of a ski binding heel, but can be applied to any fastener, such as a front stop or a different heel, in which a release spring is mounted in compression within a body having a first end in connection with a jaw and a second open end opposite the jaw.
