Definitions

  • the present invention relates to a binding of a shoe to a gliding board. It relates in particular to the rear part of a binding of a shoe on a gliding board, called heel.
  • the invention finds particularly advantageous application of alpine ski boot bindings and in particular so-called hiking bindings.
  • abutment intended to secure the front of the shoe to the board and a heel to fix the heel of the shoe to the board.
  • the heel supports two rods each having a free end which is respectively intended to penetrate into a corresponding housing made in the heel of the shoe as described, for example, in the document EP 0 199 098 .
  • the boot In certain situations, for example in the event of a fall of the user, the boot must be able to be released immediately from the binding.
  • the attachment incorporates one or more mechanisms for this automatic release of the shoe at the level of the heel and / or at the stop. This release function is called a "trigger".
  • the heel comprises in general a plurality of holding means, typically springs, which exert a force tending to bring the two free ends of the rods together or bring them back to a neutral position.
  • the distance between the two free ends of the rods is thus elastically constrained.
  • the heel housing of the shoe defines two symmetrical guideways with respect to a median axis of the foot.
  • Each of the two guide paths has an engagement zone in which a stem of the heel piece is intended to penetrate as the heel approaches the heel piece.
  • Each of the two guideways then continues with a guide zone in which one of the rods is guided until a locking zone is reached.
  • the heel is firmly held in the heel, both vertically and laterally.
  • the two guide zones, each associated with a rod mutually separate the two ends of the rods that come close once they have reached the locking zone. Since the locking zone, the springs of the heel tend to bring the two free ends of the rods and maintain them in the blocking zone.
  • the heel piece For a lateral release, the heel piece must be turned to get the free ends of the stems of the locking zones away. In this case, the ends exit directly from the associated blocking zones, without passing through the guide zones.
  • the document EP 2 384 794 proposes a solution in which two springs force the two rods for the vertical release.
  • the same springs are part of the lateral release mechanism.
  • the main body supporting the rods is rotated about a base during the lateral release.
  • This main body also supports a control body with a pin, extending vertically downward.
  • the control body is constrained by springs housed in the main body.
  • the pin cooperates with a "V" shaped cam surface formed on the base.
  • the pin then cooperates with the cam surface of the base which causes a sliding of the control body tending to constrain the springs.
  • the cam surface and the dimensioning of the springs define the lateral force to be exerted to obtain a determined angle of rotation of the body.
  • the mechanism has a height requirement because the vertical trigger mechanism and the lateral trigger mechanism are vertically superimposed. Although the device is lightened in number of parts compared to similar heels, it still has a large number of parts.
  • the kinematics of the control body has several areas of contact and friction that can interfere with the proper functioning of the trigger mechanisms by wear or jamming. The trip values can then be out of adjustment.
  • the document DE 10 2011 079 210 shows a heel piece including the features of the preamble of claim 1.
  • the object of the invention is to provide an improved heel.
  • One goal is to offer a compact heel.
  • Another goal is to offer a robust heel.
  • Another goal is to offer a lighter heel.
  • an object of the present invention relates to a heel of a binding of a boot on a gliding board as defined in claim 1.
  • the heel has a shim mounted on an upper portion of the chassis below which pivots at least a portion of the body.
  • Another object of the present invention relates to a shoe attachment system on a gliding board comprising a front stop configured to secure the front of the shoe with the gliding board and comprising a heel according to the invention.
  • Another object of the present invention relates to a gliding board comprising a heel piece according to the invention.
  • the figure 2 illustrates the main directions.
  • the longitudinal direction corresponds to the X axis.
  • the transverse direction corresponds to the Y axis.
  • the vertical direction corresponds to the Z axis.
  • the heel 100 is shown attached to the upper face 21 of a gliding board 20 of a ski.
  • the heel 100 comprises a frame 110 having a base 111 configured to be fixed to the gliding board 20, in this example by screwing through openings of screw passages 114 not shown.
  • the base can be assembled to the ski by a slide-type connection, in a longitudinal direction to the ski. This thus makes it possible to adjust the longitudinal position of the heel piece so as to adjust the binding with respect to the size or for a "back" function (maintain contact between the heel piece and the shoe when the ski flexed in a downhill configuration) .
  • a means for blocking the longitudinal displacement of the frame to the desired position there is provided.
  • a means is provided to compensate for the longitudinal displacement of the chassis to maintain it at a desired position even when the ski flexes.
  • the base is considered to be fixed to the gliding board because, in use, its position on the ski does not vary or little.
  • the frame 110 also has a vertical extension 112 integral with the base 111 and extending upwardly therefrom in a vertical direction.
  • the heel 100 also comprises a body 130 rotatably mounted on the vertical extension.
  • the body 130 comprises a sleeve 131, of generally cylindrical shape, having a bore inside which is inserted at least a portion of the vertical extension 112.
  • the vertical extension 112 is shaped to cooperate with the sleeve 131 so as to guide the latter in rotation about an axis Z1.
  • this axis of rotation corresponds to the vertical when the ski is laid flat.
  • the frame 110 also comprises a stop 120 integral with the vertical extension 112.
  • the stop is fixed by a screw 119 on the upper end of the vertical extension 112.
  • the stop is placed above the sleeve 131 and has at least one radial dimension greater than the bore of the sleeve.
  • this stop 120 prevents or limits the sliding of the body 130 along the axis of rotation Z1 in a first direction, that is to say upwards in the figures.
  • the vertical extension 112 forms with the base 111 a single piece.
  • the vertical extension 112 has at its upper end a housing 113 configured to partially accommodate a vertical portion 123 of the abutment 120, the vertical portion 123 extending downwardly.
  • the cooperation of the inner and outer shapes respectively of the housing 113 and the vertical portion 123 ensures a good relative positioning between these parts.
  • the vertical portion 123 of the abutment 120 which has an internal housing, configured to receive the end of the vertical extension 112.
  • the chassis 110 composed in particular of the base 111, the vertical extension 112 and the stop 120, thus forms a bearing for the rotational guidance of the body 130.
  • the body is intended to support two rods 51, 52, each having a free end 53, 54 intended to cooperate with a heel 11 of a shoe 10.

  • the contact zone 115 may be covered with a coating for reducing the frictional wear between the rods 51, 52 and the contact zone 115.
  • the rotation of the body is obtained during the lateral release resulting from a torque exerted on the shoe about a vertical axis located substantially at the front of the shoe. This pair is transposed by a substantially lateral force as mentioned above. Because the heel rotates about a vertical axis disposed at the front (at the abutment of the attachment), the arcuate path further promotes the removal of the free ends 53, 54 of the heel housing.
  • the withdrawal of the free ends 53, 54 of the bead housing is made on a substantially horizontal plane, unlike a vertical trigger where the withdrawal is carried out in a substantially vertical plane.

  • This pair may also be intentional, as is the case when the user does not wish to fix his heel 11 to the heel 100 but wishes to keep it free.
  • a pivoting of the body 130 around the axis of the frame 110 then makes it possible to rotate the rods 51, 52 so that their ends are no longer facing the heel 11.
  • this design avoids a possible maladjustment or a drift over time of the value of the triggering thresholds.
  • the contact zone 115 is designed so that the maximum spacing of the ends 53, 54 of the rods 51, 52 is obtained when the body 130 has rotated by an angle of between 30 ° and 70 °.
  • this construction allows an effective lateral release while distributing the restoring force of the rods on at least two surfaces, which effectively contributes to the robustness and reliability of the heel 100.
  • the contact zone 115 is also dimensioned so as to provide elastic return of the body 130 and rods 51, 52 to the descent configuration, as soon as the body pivots at least to the lateral release angle. Thus, when the body rotates with a lower return angle to the trigger angle, it undergoes a torque tending to bring it back to its neutral position when it is no longer requested.
  • the contact zone 115 may also allow springback for a return angle greater than the trigger angle.
  • the return angle limit can be between 30 ° and 90 °.
  • the lateral release kinematics is minimalist and relies on parts that are simple to manufacture, robust and limited in number, which reinforces the reliability and lightness of the trigger mechanism.
  • the fork 50 is also responsible for the vertical trigger. Indeed, in case of significant vertical force, for example during a fall before, corresponding to an upward vertical force exerted by the heel 11, the shoe disengages from the rods 51, 52. Because the zone of blocking 12 has, at the entrance, a slope, inclined outwards, towards the bottom of the heel 11, the free ends 53, 54 of the rods 51, 52 slide on this slope by moving apart and out of the blocking zone 12. The free ends 53, 54 then escape from the housing of the heel 11. The heel 11 is released from the heel 100. When leaving the locking zone 12, the rods 51, 52 deviate. This spacing of the rods is effected against the elastic force exerted by the joining portion 55.
  • each upper flange 134 of the body 130 comprises a lower surface 1341 inclined with respect to a horizontal plane, at an angle ⁇ , as seen in FIG. figure 3 .
  • This inclination of this lower surface 1341 combined with the slope of the locking zone 12 contributes to facilitating the spacing of the free ends 53, 54 of the rods 51, 52.
  • a vertical upward force of the rods 51, 52 on these inclined lower surfaces 1341 generates a transverse component in reaction, tending to separate the free ends 53, 54.
  • the fork 50 comprising the rods 51, 52 and the joining portion 55 form a single piece, which increases the robustness of the heel 100.
  • the fork 50 is made of metal, for example High Elastic Steel.
  • At least the portions of the rods 51, 52 intended to cooperate with the contact zone 115 are covered with a coating or a part designed to reduce frictional wear.

  • the cross member 153 and / or the arms 152 then serve as a support zone to the heel 11 in the activated position.
  • the wedge In the first position, called “deactivated” or “retracted", the wedge is positioned so as not to hinder the vertical movement down the heel of the user. The user can then fix his heel to the heel 100 if it is configured for descent.
  • the user In a ski touring configuration, the user only fixes the front of the shoe 10 on a shoe retainer called “front stop” and releases the heel of the heel.

  • This climbing configuration is used to climb on flat or on slopes.
  • the device To facilitate the thrust of the skier, the device provides different heel support heights. For flat terrain, the support height should be close to the top surface of the ski. Conversely, the more you have the slope, the better it is to have support height under the heel.
  • Rotating the body 90 degrees subtracts the free ends from cooperation with the heel housing.
  • the heel can then directly rest on the upper surface of the ski or on the base 111.

In this position, the climbing wedge 150 prevents the heel from reaching the base 111 or the gliding board 20, and assists the user in a steep ascent phase.

  • the shim 150 is configured, in the activated position, to cooperate with the rods 51, 52, so as to prevent their spacing being sufficient for the body 130 to be able to turn about the vertical extension 112.
  • two abutment portions 155 carried by the arms 152 of the shim 150 are respectively positioned close to each of the rods 51, 52 outside relative to the axis of rotation of the body 130 This proximity allows a direct contact between the abutment portions 155 and the rods 51, 52.
  • the spacing of the rods 51, 52 is then limited, which blocks the rotation of the body 130. Any angular displacement of the body 130 is then prevented. or greatly reduced.
  • This feature makes it possible to avoid any inadvertent rotation of the body or of the climbing wedge while the climbing wedge 150 is activated, and this without adding complexity, weight or bulk to the heel piece 100. Thus, it secures this configuration, maintaining the operational climb wedge.
  • the abutment portions 155 are carried by an additional cross member 154 extending from one arm 152 to the other of the shim.
  • This additional cross member 154 bears on the rods 51, 52, which makes it possible to limit the rotation of the climbing wedge about its articulation axis 151. The user can then easily set up the climbing wedge in this stable indexed position. The heel bearing force is thus taken up by the rods 51, 52.
  • the body 130 comprises assembly means for alternately locking forks 50 having arms 51, 52 of different lengths with the body 130, while maintaining a predetermined identical distance between the free end 53, 54 of each rod 51, 52 and the axis Z1 around which the body rotates 130.
  • a fork 50 can be inserted and removed from the body 130 in a particularly simple manner and without the need for tools.
  • a first fork can be replaced by a second fork whose properties, in particular the stiffness of the spacing between the two rods 51, 52, are different from those of the first fork. It is thus possible to set the trigger threshold according to the user.
  • the assembly means are deactivatable when the body 130 has a determined angular position relative to the frame 110, typically an angle of 90 ° with respect to the descent configuration. This determined angular position is designated angular position of unlocking.
  • the assembly means allow withdrawal of the fork 50 only when they are deactivated.
  • the heel 100 is configured to prevent deactivation of the assembly means when the body 130 is not in the unlocking angular position.
  • the assembly means comprise a locking cap 160 articulated pivotally on the body 130, about a substantially horizontal axis 161.
  • the latch cover 160 has two arms 166 which extend from the hinge axis 161 to a holding cover 168 of the fork.
  • a passage opening 164 is thus created between the arms.
  • a locking tab 167 extends longitudinally of the holding cover 168 inside the passage opening 164.
  • the lower face of this cover 168 is arranged opposite the fork 50 and then prevents the fork 50 from moving.
  • the underside of the cover has notches 162 defined by walls 163 each forming an axial stop. These axial stops are shaped so that the fork 50, once inserted into a notch 162, can no longer slide horizontally.
  • the lock stop 121 appears clearly on the figure 2 . In this example, it is carried by the stop 120. It is vertically positioned to the right of the locking cap 160 when the body 130 is not in the angular locking position.
  • the stop 120 has a portion 122 which extends horizontally rearwards and a lower face forms the locking abutment 121.
  • the horizontal part 122 is dimensioned so that, when the body 130 is in the unlocking angular position, the locking stop 121 is not vis-à-vis the locking tab 167 of the cover.
  • the locking cap 160 can pivot about its axis 161.
  • the portion 122 of the stopper then passes through the passage opening 164. The user can lift the locking cap 160 and move it away from the longitudinal extension 132 of the body 130.
  • the fork 50 can then be removed.
  • the heel 100 allows to unlock the locking cap 160 by a simple rotation of the body 130 which can be exercised manually and thus ensures the proper locking of the cover 160 in the other positions.
  • This solution is particularly robust, reliable and allows to keep a limited weight.
  • the stiffness of the spacing between the free ends 53, 54 of the rods 51, 52 depends in particular on the length of the rods, that is to say on the distance between each free end of a rod 51, 52 and the portion
  • a fork 50 with shorter stems has a stiffness at the spacing of its ends 53, 54 higher than a fork 50 longer rods.
  • the distance between the free ends 53, 54 of the rods 51, 52 and the axis around Z1 which rotates the body 130 should preferably be identical, regardless of the length of the fork 50, in order to always cooperate with the housing made in the heel 11.
  • the heel 100 makes it possible to position the joining portion 55 away from the axis of rotation of the body 130.
  • the longitudinal extension 132 supporting the joining portion 55 and / or, as is the case in the illustrated example, the underside of the cover has several notches 162, each corresponding to a position of the fork 50 by relative to the axis of rotation Z1 of the body 130.
  • the locking cap 160 has three notches 162, the fork 50 shown being sized to fit in the intermediate notch.
  • the invention makes it possible to adapt in a particularly fast, simple manner and without requiring tools, the trigger threshold of the heel This is particularly advantageous when the equipment is rented since the triggering threshold can easily be adapted to the weight or the level of the client who will use the heel piece 100.
  • the locking cap 160 comprises a housing 165 for the additional cross member 154 of the shim, which reduces the bulk.
  • This construction allows a common part, the fork 50, to provide the vertical trigger and the lateral trigger.
  • the lateral trip value is not the same as the vertical trip value.
  • the vertical trip value must be substantially four times greater than the lateral trip value.
  • the shape and / or the dimensions of the fork can be modified, for example the section of the rods 51, 52 and / or the joining portion 55.
  • the vertical / horizontal trip ratio can be adapted by modifying the contact zone 115.
  • Another way of modifying this ratio is to modify the inclination of the lower surface 1341 of the upper flange 134.
  • the vertical / horizontal trip ratio can be adapted by sizing the contact zone 115 so that it biases the rods 51, 52 when in a neutral position, in the descent configuration.
  • the contact zone causes the initial spacing E1 free ends 53, 54 to facilitate vertical triggering.
  • the dimensioning of a fork thus defines a single vertical trip value and a single lateral trip value. It is not possible to set the lateral trip value independently of the vertical trip value or vice versa. These two trigger values are therefore directly linked and depend on the design of the fork.
  • the contact zone 115 is dimensioned so that when the body 130 has a predetermined angular position relative to the frame 110, the two rods 51, 52 are no longer in contact with the contact zone 115 or are respectively slightly in contact with a determined part of the contact zone 115, associated with each rod, to allow removal of the rods 51, 52 outside the contact zone 115 without tools, preferably by a manual action exerted with two fingers only.
  • the rods 51, 52 do not cooperate with the contact zone 115.
  • the fork does not clamp the contact zone 115 and can be easily replaced by another, for example when it is worn.
  • FIG. 11 This feature is illustrated in figure 11 .
  • the body 130 is rotated more or less 90 ° with respect to the descent configuration in which the rods 51, 52 are facing the housing of the heel 11.
  • the contact zone 115 carried by the vertical extension 112 has a face facing the rods 51, 52 which is at a distance D3 from the axis of rotation Z1 of the body 130.
  • This distance D3 is dimensioned so that that the distance between the two faces of the vertical extension 112 is less than the spacing E3 of the ends 53, 54 of the rods 51, 52 at rest, that is to say without being solicited in spacing: 2 x D3 ⁇ E3.
  • the contact zone 115 does not remove the rods 51, 52, which can then be removed easily by a simple horizontal sliding movement.
  • a first variant concerns the shim 250.
  • the shim 250 is articulated in rotation on the chassis 110.
  • the hinge pin 251 of the wedge 250 is substantially horizontal and transverse to the ski so that the wedge can rotate from the front to the back of the heel piece 100.
  • the shim 250 is provided on an upper portion 220 of the frame 110 below which pivots at least a portion of the body 130 of the heel around a substantially vertical axis Z1.
  • the body is pivotally mounted around the frame fixed to the gliding board.
  • the frame 110 passes through the body 130 and serves as a bearing on the body 130 for its rotation about a substantially vertical axis Z1.
  • the rods 51, 52 ensuring the release of the heel are disposed on either side of the frame 110 and, more particularly, the portion passing through the body.
  • the shim 250 is made independent of the movement of the body 130. In particular, it is not rotated when the body 130 rotates.
  • the shim is directly attached to the frame fixed on the gliding board, if it is laterally supported on the shim, its position remains always the same with respect to the gliding board. This lateral support can occur when the skier moves in a slope.
  • the climbing wedge is thus continuously functional or non-functional, according to the voluntary action of the user, regardless of the angular position of the body.
  • the figure 12 illustrates the climb wedge 250 deactivated.
  • the figure 13 illustrates the climbing wedge 250 activated with the body 130 in the same position as the figure 12 .
  • the figure 14 illustrates the climbing wedge 250 activated with the body 130 having rotated here at 90 °, from the position of the figure 13 . It can be seen that the climbing wedge 250 has not turned and remains active.
  • a second variant relates to the means for fixing forks 50 of different length while maintaining a constant distance between the ends 53, 54 of the rods 51, 52 and the axis of rotation Z1 of the body 130.
  • the junction portion 55 of a fork 50 is inserted into a holding piece 270 attached to the body 130, for example by being fixed on the underside of a longitudinal extension 132 of the body 130.
  • the longitudinal extension 132 forms an extension of the upper rim 134 to the difference of the first embodiment in which the longitudinal extension 132 forms the extension of the lower edge 133.
  • This holding piece 270 has a groove sized to accommodate at least a portion of the joining portion 55.
  • the holding piece 270 is also constructed to prevent the horizontal movement of the fork 50, including its sliding parallel to the rods 51, 52.
  • the cooperation of the retaining piece 270 with the underside of the longitudinal extension 132 of the body 130 defines a housing 273 of closed section which prevents any vertical withdrawal of the fork 50. The latter is blocked when the piece of 270 is attached to the body 130.
  • the holding piece 270 is fixed by at least one screw 271 or a pin screwed into the body 130.
  • a set of holding pieces 270 which all have a different distance between their junction portion housing 273 55 and the axis of rotation Z1 of the body 130.
  • That 270a of the figure 16 blocks the joining portion 55 at a distance D4 from the axis of rotation Z1 of the body 130.
  • That 270b of the figure 17 blocks the joining portion 55 at a distance D5 from the axis of rotation Z1 of the body 130 which is very significantly smaller than D4.
  • This second holding part 270b therefore allows the use of a fork 50 provided with longer rods and thus allowing a lower trigger threshold.
  • the body may comprise several screw holes 136 through which the screw 271 passes. These screw holes 136 are aligned longitudinally, which makes it possible to increase the number of possible configurations.
  • the figures 15 and 18 illustrate an embodiment with two screw holes 136.
  • the same holding part 270 comprises two housings disposed on the same face of the holding part 270 or on two opposite faces. In the latter case, it is sufficient to turn the retaining piece 270 to use forks 50 of different dimensions.
  • the holding pieces 270 may also have housings of different sections to accommodate forks 50 of different sections.
  • the climbing wedge 250 comprises means for indexing the angular position.
  • the user can thus more easily position it in one or the other of the activated and deactivated positions. Moreover, this indexing prevents the climbing wedge 250 from turning involuntarily from a position assigned to it by the user.
  • the arms 256 are mounted on the abutment 220 with a transverse clearance so as to allow slight deformation of the arms in a direction transverse to the ski.
  • the protrusion 256 is housed in a first part of the groove 224 (the upper part or the lower part). This configuration is stable and indexed.
