Definitions

  • the present invention relates to a device for retaining a shoe on a sliding board as well as a sliding machine comprising a sliding board, such as a cross-country ski or touring ski equipped with said retaining device.
  • a retaining device is sometimes referred to as a “stopper,” “front stopper,” or “fastener.”
  • a sliding machine is a piece of equipment on which a person stands when using this machine for practicing a sliding sport, while being attached by at least one of their shoes. on this machine.
  • the ski In the case of classic or alternative cross-country skiing, the ski is cambered and defines, under the boot, an area which, by default, is not in contact with the snow. This area constitutes a “wax chamber”. In this area, grip wax can be added to increase the grip of the ski on the snow in order to prevent the ski from rolling back, which allows effective pushing with the foot.
  • grip wax By modifying the longitudinal position of a boot retaining device on the ski, it is possible to adjust the contact zone between the ski and the snow depending on the weight exerted by the skier, favoring sliding or skiing. hooks. When turning, the skier has to lift one ski to bring it back towards the other ski.
  • the lifted ski is connected to the skier only by the front end of the boot and it is important that the ski is correctly balanced. If the ski leans forward or backward, it can contact the snow, which can slow the skier down or throw them off balance. Adjusting the length of a device for retaining a boot on the ski therefore makes it possible to adjust the balance of the ski in this raised configuration.
  • the document EP3511057 describes a retaining device for a cross-country ski boot whose longitudinal position is adjustable relative to a mounting plate fixed to the ski.
  • the retaining device comprises a frame and a stopping element movable relative to said frame, in a transverse direction, between an active position for which the stopping element cooperates with a rack secured to a mounting plate and a position inactive for which the stopping element no longer cooperates with the rack.
  • the stop element can be operated manually, directly by the user's finger, but can also be switched from its inactive position to its active position by means of a cam provided on the actuating lever of the holding mechanism of the shoe. So when the lever is lowered, it pushes the stop element into its active position and locks it.
  • the actuating lever is mounted movable in rotation relative to a jaw movable in translation relative to the chassis.
  • the stopping element By being movable transversely, the stopping element can be designed to facilitate its manipulation from an inactive position to an active position or vice versa.
  • this construction requires providing a suitable location for the kinematics of the stopping element.
  • this induces a bulky dimensioning of the binding and, consequently, the addition of mass to the front of the binding.
  • the positioning of the pivot point between the boot and the sliding machine relative to the balance point of the ski is shifted forward, which penalizes the performance of the ski.
  • this construction does not allow actuation of the stop element by actuation means of the retaining device when the shoe holding mechanism is in a shoe release configuration.
  • the use of an actuation means to act on the stopping element allows better ergonomics for adjusting the longitudinal position of the retaining device, particularly with regard to controlling the force to be applied to actuate the stopping element.
  • the aim of the invention is to propose an alternative and improved device for retaining a shoe on a sliding board.
  • One aim is in particular to propose a mechanism for adjusting the longitudinal position of a retaining device on a more compact sliding board allowing better balance of the sliding machine.
  • Another aim is to propose a mechanism for adjusting the longitudinal position of a retaining device on a sliding board that is easy to handle, and in particular without tools.
  • Another aim is to propose a mechanism for adjusting the longitudinal position of a retaining device on a gliding board, independent of the shoe holding mechanism, and having simple and reliable kinematics.
  • the retaining device is characterized by the fact that the actuating means is mounted movable only in rotation relative to the chassis.
  • the retaining device is compact, light and less bulky.
  • the center of gravity of the binding can be brought back and thus not penalize the positioning of the pivot point between the boot and the sliding machine in relation to the balance point of the ski.
  • the performance of the sliding machine can thus be improved.
  • the actuation means can be ergonomic, being easy to handle, due to the fact that its kinematics are simple and direct in relation to the chassis. Its direct connection with the stopping element allows good operation of the longitudinal immobilization mechanism, with reliable movement of the stopping element, requiring little handling effort and operable without tools.
  • the actuation means makes it possible to act on the stopping element independently of the shoe holding mechanism. This construction thus makes it possible to design an actuation means capable of being housed inside the actuation lever of the maintaining the shoe so as not to be exposed or accessible when the operating lever is lowered.
  • the invention also relates to a sliding machine comprising a sliding board and a retaining device as defined above.
  • the invention relates to a retaining device 1 for a shoe 5, also called a binding, intended to be assembled at an interface 2, or mounting plate, secured to a gliding board or ski 3.
  • a retaining device 1 for a shoe 5, also called a binding intended to be assembled at an interface 2, or mounting plate, secured to a gliding board or ski 3.
  • the interface 2 and the sliding board 3 form a single, single piece.
  • the interface 2 is a separate component fixed on the upper face 32 of the sliding board 3, opposite its sliding surface 31.
  • the sliding board 3 extends along a longitudinal axis X3 .
  • the retaining device 1 is mounted with the possibility of sliding relative to the ski 3, along its longitudinal axis X3.
  • the assembly composed of the retaining device 1, the interface 2 and the sliding board 3 forms a sliding machine 4.
  • the invention is more particularly aimed at a sliding machine intended for cross-country skiing or ski touring.
  • a sliding machine is equipped with a retaining device designed to secure the front of the shoe to the sliding board.
  • the retaining device does not secure the heel of the shoe to the gliding board.
  • the skier can then freely lift his heel, without lifting the ski.
  • the sliding machine may nevertheless include a guiding edge arranged so as to limit the lateral movement of the heel when it cooperates with the guiding edge, when the heel rests on the ski.
  • the interface 2 is fixed on the ski 3 so that the longitudinal axis X3 of the ski and the longitudinal axis X2 of the interface are parallel.
  • the interface 2 comprises an insert 22 and a main body 21 comprising a central part 212 and two side wings 213 which extend on either side of the central part 212.
  • the outer edge of each side wing 213 forms a side rail extending in a direction parallel to the longitudinal axis X2 of the interface.
  • the main body 21 has an upper face 211.
  • the assembly of the main body 21 on the ski 3 is carried out by any appropriate means. This can be by gluing or by screws.
  • the main body 21 comprises a housing 2121 intended to receive an insert 22.
  • the insert 22 is a component of the interface 2.
  • the insert 22 comprises an upper surface 221 as well as a series of notches 222 extending from the upper surface 221.
  • the sides of each notch are preferably inclined so that the base of the notch is thicker.
  • the thickness E222 at the top is preferably greater than two millimeters.
  • the height H222 of a notch is preferably greater than two millimeters.
  • the series of notches 222 forms a complementary indexing means 20 intended to cooperate with an indexing means 131 of a longitudinal stopping element 13 so as to be able to immobilize the retaining device along the sliding board, in the one of several predetermined positions.
  • each notch 222 extends along a vertical axis Z, in the direction of the retaining device. All the notches 222 are aligned in a longitudinal direction X parallel to the longitudinal axis X2 of the mounting plate. In use, the notches 222 are heavily stressed because they are the ones which hold the retaining device in position, in the longitudinal direction. Also, it is preferable to choose a suitable material for these notches.
  • the proposed construction consisting of adding a removable insert has several advantages. This allows, on the one hand, to change the part if the notching is damaged and, on the other hand, the use of more rigid material locally, where necessary, without penalizing the weight of the interface and therefore of the ski.
  • the insert may be reinforced polymer or metal while the rest of the interface is unfilled plastic.
  • the insert can be removably mounted on the interface by any suitable means. This can be by clipping or using a screw.
  • This solution can be transposed to any type of indexing of a system for adjusting the longitudinal position of a retaining device relative to a ski and is therefore not limited to the embodiment illustrated here.
  • the indexing means 131 and the complementary indexing means 20 can be produced by one or more pins cooperating with holes.
  • the series of notches 222 can be replaced by a series of housings, notches, recesses corresponding to the gap between two notches. The notches are not necessarily rectilinear in a transverse direction.
  • the interface 2 comprises connection means making it possible to hold the insert 22 and the main body 21 together, in all directions, once the two parts are assembled.
  • connection means can be removable, to allow replacement of the insert if necessary. According to a variant, these connection means cannot be dismantled without damaging the interface.
  • the complementary indexing means 20 and the interface 2 form a single, single piece.
  • the notches 222 are made directly in the central part 212 of the main body 21 and not on an insert 22 attached.
  • the notches 222 are made of a material other than that of the main body 21.
  • the notches 222 are provided on an insert 22 which is overmolded to the main body 21.
  • the assembly consisting of the main body 21 and the the overmolded insert 22 then forms the interface 2.
  • the use of two different materials between the insert and the rest of the interface makes it possible to locally reinforce the interface, where this is necessary, for example, at the level of the transmission of longitudinal forces.
  • the overmolded insert 22 is made of reinforced polymer while the rest of the interface 2, namely the main body 21, can be made of unfilled polymer.
  • the interface 2 is glued to the upper face 32 of the gliding board 3. This can be achieved by separate gluing of the constituent parts of the interface, the insert 22 on the one hand and the main body 21 on the other hand. Alternatively, this can be achieved by simultaneous bonding of the constituent parts of the interface, either with a one-piece interface, the interface then being single-material or multi-material overmolded, or with a previously assembled interface, the insert then already being integral with the main body via means of connection.
  • the interface 2 is arranged between the sliding board 3 and the retaining device 1. It carries the complementary indexing 20.
  • the retaining device 1 is a cross-country ski binding and comprises a frame 11, a mechanism 12 for holding in position a hooking element 51 belonging to the shoe 5, a longitudinal stop 13, an actuation means 14 of the longitudinal stop element and a return means 16 making it possible to bring the heel of the boot towards the ski.
  • the chassis 11 is designed to be assembled at the interface 2. It extends along a longitudinal axis X1 substantially parallel to the longitudinal axis X2 of the interface when the chassis is mounted on the interface.
  • the chassis comprises a lower face 111 intended to face the upper face 211 of the interface 2.
  • the lower face 111 is delimited laterally by two edges 112, extending along a vertical axis Z, in the direction of the interface, from the underside.
  • Each rim 112 comprises an internal lateral groove 113 oriented in a longitudinal direction parallel to the longitudinal axis X1 of the chassis.
  • the two internal side grooves 113 face each other.
  • Each internal lateral groove 113 is intended to cooperate respectively with a rail formed by one of the lateral wings 213 of the interface 2 so as to guide the chassis in translation relative to the interface, in a longitudinal direction maintaining the relative position between the chassis and the interface in a Z direction, normal to the upper face of the interface. This cooperation thus defines a slide-type connection between the chassis and the interface ensuring the longitudinal sliding of the retaining device relative to the ski.
  • Other longitudinal guidance solutions could be considered.
  • the chassis 11 carries, in its upper part, the mechanism 12 for holding in position a hooking element 51 belonging to the shoe 5.
  • the hooking element 51 is a transverse shaft integrated in a recess in the front of the sole 52 of the shoe 5, extending in a transverse direction Y5.

  • This arrangement allows the attachment of the attachment element to be joined to the retaining device while allowing the rotation of the shoe around a transverse axis Y1 to the retaining device.
  • the movable jaw 122 is spaced from the fixed jaw 121 so as to create an upper passage for the hooking element 51 so that it can disengage from the interstitial space defined previously. This configuration allows the attachment element to be separated from the retaining device.
