Definitions

  • the invention relates to a set of two retaining elements provided for hold a skier's shoes on a pair of boards, especially on a pair of skis.
  • the invention also relates to a set of two retaining elements paired with a set of two right and left shoes for each of feet of a skier.
  • the stiffness of the spring is adjustable, so that the shoe is released from the fastening element for a stress exceeding a stress threshold determined.
  • This threshold is commonly referred to as the trigger threshold.
  • the shape of the front and rear tips of the shoe has been standardized.
  • the applicable standard has the ISO 5355 reference.
  • the fastening elements are designed to be compatible with the standardized areas of the shoe and ensure the release of the shoe has determined trigger values.
  • a shoe is retained by a retaining or fastening element front whose jaw is movable at least laterally inward or the outside of the foot.
  • the jaw of the retainer is provided for trigger, i.e. to release the shoe during torsional stress excessive exercise on the skier's leg.
  • the current bindings present a trigger point generally equal inward and outward of the foot.
  • the major disadvantage of this kind of device is that it requires pairing between the boots and the skis, i.e. the right and left skis must be necessarily identified, and that the skier must above all put on the right ski with his right shoe and the left ski with the left shoe.
  • it is materially possible to reverse the two skis i.e. to put on example the left ski with the right shoe.
  • the effect of the asymmetry in the triggering of the fixation plays in reverse, without it is possible to remedy it other than by exchanging the two skis.
  • the problem posed by the invention is to improve the operating mode existing retainers. It consists in particular in providing the elements to retain an asymmetric trigger threshold, and to improve the operation of such trigger threshold retaining elements asymmetrical.
  • Each retaining element has a jaw retaining jaw shoe movable laterally, on both sides, towards the inside or outside of the ski, against the return force of a spring.
  • the jaw and the spring are provided for release the shoe beyond a determined trigger threshold.
  • Each retaining element is additionally equipped with an adjustment mechanism, which allows adjust the trigger level of the retaining element as desired asymmetrical, according to the direction of movement of the jaw, and a button or control lever that activates the mechanism from the outside adjustment.
  • the skier can adjust the threshold at will triggering of its retaining elements in different ways depending on whether they release the shoe inward or outward of the foot.
  • the retaining elements and the shoe have visual cues that cooperate together to view the position in which each button should be placed. Indeed, if we can easily switch right and left skis, it is not reasonable to exchange the right and left shoes.
  • the shoes therefore wear visual cues which are for example symmetrical, according to which the buttons of the two retainers must be adjusted, so as to be somehow polarized as right element and left element, respectively.
  • the shoes and the retaining elements have mechanical benchmarks that only allow the engagement of the shoe in the retainer only if the control button is placed in the position suitable for the position of the retainer, right or left.

  • Figures 1 to 3 show by way of illustration of the invention an element of retainer 1 of a set of elements comprising two elements. Both elements of the set are constructed identically. To simplify the reference notation, the same references should be assigned to the same members of the two retainers, when so designated general, and to assign to these references the prime exhibitor or the second exhibitor when designated as a specific member of the premium retainer or the second retainer, respectively, of the assembly.
  • Element 1 shown in Figures 1 to 3 includes a base 2 surmounted by a hollow body 3 having a side wall and an upper cover.
  • the base 2 extends rearward to form a support plate 5 provided to receive the shoe sole.
  • the retaining element also has a jaw formed by two wings 7 and 8 for retaining the shoe.
  • the wings are independent, respectively articulated around axes vertical 9 and 10.
  • the wings extend inward respectively, beyond axes 9 and 10 by returns 7a and 8a.
  • the wings include a sole clamp which ensures the vertical retention of the shoe, in addition to the retention lateral.
  • the jaw could have another nature, in particular be in one piece, integrally connected to a pivotally mounted body around a central pivot. Many known constructions are possible.
  • the jaw At rest, the jaw has a position substantially aligned with the axis longitudinal defined by the ski. In the illustrated case, at rest, the wings 7 and 8 are closed towards the median longitudinal axis which is shown diagrammatically by its trace 11 in figure 2.
  • the body 3 of the retaining element houses a spring 12, to which are transmitted the stresses that the shoe exerts on the wings of the jaw, and which, in back, exerts on the wings an elastic return force towards their respective rest position.
  • the spring is connected to the jaw by a transmission link of movement.
  • connection between the spring and the wings of the jaw comprises a longitudinal tie rod 13 which is cylindrical.
  • the tie rod is engaged in the turns of the spring. He presents to his front end a stop washer 14 against which the front end of the spring relies.
  • the washer is connected to the end of the spring by a screw 15 which allows adjust the initial compression of the spring. Screw 15 is accessible from the front of the retainer through a hood opening.
  • the spring bears against a support wall 18 which is secured to the body or its base.
  • the wall support 18 also serves as a stop for the returns 7a and 8a of the wings, for a wing rotation inward. This position in abutment against the support wall defines the rest position of each wing.
  • the tie rod crosses the wall 18 and opens backwards between the two wings. At this level, it presents a part 20 of smaller diameter, with a head 21. At the birth of this part more small diameter, the tie has a shoulder 22. On the weakest part diameter are mounted a ring 24, on the side of the shoulder 22, and a rocker floating 25 on the side of the head 21.
  • the floating rocker is wider than the head 21, and its dimensions are such that it gives the returns 7a and 8a of the wings a surface support by which the returns of the wings can stress the front tie in back against the spring return force.
  • part 20 more small diameter is an independent element which is assembled for example by screwing or any other means suitable for the rest of the tie rod.
  • the rocker 25 is held on the part 20 of the tie rod, resting between its head 21 and returns 7a and 8a of the wings.
  • the head 21 of the tie rod has a section square, and the tie has two beads laterally which give good support for the rocker, especially during the oscillating movements which will be described later.
  • the rocker 25 bears against the ring 24.
  • the ring 24 is pivotally mounted around the part 20 of the tie rod. Forward, the ring bears against the shoulder 22.
  • the ring has an outside diameter equal to that of the front part of the tie rod, but this is not essential.
  • the ring has a length greater than the travel of the tie rod between the rest position and the release of the shoe.
  • the assembly of the rocker and the ring is provided so that, at least at rest, the ring can pivot freely around part 20. That is to say than the rocker and the ring are mounted on the tie rod, between the head and the shoulder 22 with slight play in a longitudinal direction.
  • the rocker 25 is floating, that is to say it can oscillate in a plane horizontal, depending on the position and displacement of its various supports.
  • the rocker has a wide central opening 27 of rectangular shape. Top view, the width of this opening is greater than the diameter of part 20 of the tie rod, and preferably this part 20 has a flange 28 with a rounded edge, the outside diameter of which is substantially equal to the width of the opening 27. This flange serves to support the oscillation of the rocker, which will be described in more detail later.
  • the width of the opening 27 is however less than the diameter of the ring 24.
  • the opening 27 has a height which is slightly greater than the outside diameter of the ring 25.
  • the rocker 25 is provided for that part 20 is halfway up. Any suitable means is suitable.
  • the ring 25 has on the side of the rocker a flat bearing surface, which is vertical, except for about a quarter of a circle where the support surface is recessed.
  • the flat and vertical area is identified at 29 in the figures, and the recessed area at 30.
  • this zone 30 is aligned with the median longitudinal plane, downwards, under part 20 of the pulling. It might as well be above part 20. This position will qualified in the middle position sequence
  • Figures 7 and 8 show the connection between the wings and the tie in the middle position of the ring.
  • the wings are at rest, in position closed.
  • one of the wings, the wing 7 in this case, has opened.
  • the return 7a of the wing has driven the rocker 25.
  • the rocker 25 is held in place side by the head 20 of the tie rod, and on the other side, by reaction, it leans against the ring 24 on either side of the median longitudinal axis.
  • the rocker moves with the tie remaining perpendicular to the tie.
  • Figure 9 shows the construction after a rotation of the ring 24 on a quarter turn. This rotation brought the recessed area 30 from the rocker towards the return 8a of wing 8.
  • wing 8 has opened. In its rotational movement, the wing has driven the rocker 25.
  • the rocker rests on the head of the tie rod, and, by reaction on the ring 24 in the zone diametrically opposite to the zone 30.
  • the rocker behaves in the same way as that described above.
  • FIG 11 illustrates the rotation of the other wing, i.e. wing 7.
  • the rocker drives the head 21 of the tie rod, but this time, the rocker rests by reaction no longer against ring 24, but against return 8a on the other wing. Indeed, the rocker cannot find a support against the ring 24, because of the recessed area 30.
  • the wing 8 is in turn retained by the support wall 18.
  • the rocker 25 no longer directly transmits its movement to the pulling, it functions as a lever, which pivots on its support on the return 8a. Given the difference in the lever arm, the restoring force which opposes the opening of the wing is multiplied. The opening of wing 7 is facilitated in this position of the ring 24.
  • the zone 30 is sufficiently set back so that the wing 7 releases the shoe before the rocker 25 reaches the bottom of the zone 30. In this way, the rocker 30 remains in abutment against the return of the wing 8, and the reduction effect is maintained.
  • the opening 27 of the rocker 30 is provided in height for do not interfere with the swing of the rocker, i.e. it is greater than the outer diameter of the ring.
  • the ring 24 can also be pivoted in the other direction, to obtain the same multiplier effect with the opening of the other wing.
  • the retainer further includes means for determining manually position the ring.
  • the ring 24 has on half of its periphery a grooved area 34.
  • the grooves are oriented parallel to the longitudinal direction of travel of the tie rod.
  • this area is opposite of zone 30 of the ring, and, in the middle position of the ring, this area is located on top of the ring.
  • a rack 35 is provided to mesh with the grooves of the ring 24.
  • the rack 35 is guided in a translational movement transverse in a groove carried by the support wall 18. Naturally everything another suitable means of guidance is suitable.
  • the rack carries in its upper part a vertical rod 36.
  • Rod 36 is engaged in the teeth of a lever 37 in the form of a fork.
  • the lever is mounted pivoting about a vertical axis 38 which passes through the cover 3 of the element detention.
  • the vertical axis 38 is embedded in a lever maneuver 40 intended to be actuated simply by hand or with the stick ski.
  • the lever may have any suitable means, for example small basins 39 provided to receive the tip of the ski pole.
  • the set is planned so that a determined angle rotation of the control lever 40 causes the rotation of the ring 24 by a quarter turn to one side or the other from its position median.
  • the lever 40 is visible in Figure 1 above the cover. He is represented in its middle position which corresponds to the middle position of the ring 24.
  • Figure 1 in 40a and 40b the two directions in which it is necessary orient the operating lever to bring the ring 24 into one or other of the so-called polarization positions of the retaining element which produce a threshold of release of the asymmetrical shoe, weaker on one side than on the other.
  • the ring 24 is mounted on the part 20 of the tie rod with slight play, so that its rotation can be controlled without significant effort when the element is in the rest position. Ring 24 is not actually pressed against the shoulder of the tie rod only when a retaining wing of the shoe is stressed.
  • the tie moves in a longitudinal direction.
  • the rack does not accompany this movement, but its teeth slide along the grooves of the ring 24.
  • the length of the ring has been provided greater than the maximum travel of longitudinal displacement of the tie rod.
  • Figure 14 shows a set of two retaining elements 1 'and 1' 'which are identical to element 1 described above. These elements are represented in their shoe-ready position, that is, the shoe-ready item by the right shoe is to the right of the other element, and the element intended to be shod by the left shoe is to the left of the other element of the set.
  • Each element has an operating lever 40 'and 40' 'identical to lever 40.
  • the two operating levers have been oriented in opposite and symmetrical directions, to polarize the elements of retained symmetrically, so that for each foot of the skier, the shoe is released more easily for release of the shoe towards outside of the element, corresponding to a rotation of the foot towards the inside.
  • the operating levers allow however to modify at will the polarization of the retaining elements.
  • each use of the skis the operating levers are oriented according to the suitable polarization, and they are brought back to the middle position at the end of each use. For example, for each use, the skier presents his skis on the snow next to each other ready to be put on, and directs the levers so suitable according to the relative position of the skis.
  • the skier leaves the operating levers in their position.
  • the respective orientation of the levers is suitable or not. If it is suitable, it does not modify the setting of the operating levers, in fact, the elements of retainers are properly polarized. If the levers are not in the right place position, rather than inverting the relative position of the skis, the reverse skier simply the orientation of the levers. In doing so, it brings back each of the elements of retained in a correct position. This maneuver is carried out in a simple way, and requires no manipulation of the skis.

  • the support lines converge towards the head of the screw, and the body rests on the pivot by three zones or points, two marked 104a and 105a located in the part lower of the pivot, and the head 103a of the screw 103.
  • the base On its front face, the base has a transverse face 108 against which the return spring 115 of the retaining element exerts its action.
  • the body Towards the rear, the body has a shoe retaining jaw.
  • the jaw includes two wings 110 and 111 which form with the body a whole monobloc, or quasi-monobloc if one takes into account the means allowing to regulate the angular opening of the wings. These means are known and are not referenced in the figures.
  • the wings 110 and 111 provide lateral retention of the shoe. Account holding their position, the wings 110 and 111 retain the shoe by what we calls for a plug on rod.
  • the standardized toe of the shoe has indeed in a known manner a lower part of the sole, surmounted by a part upper which forms the base of the stem. It is on this part that the wings 110 and 111 exercise their action. Of course, this is not limiting, and the other taking of the toe cap, known as a sole plug, is also possible. Restraint vertical is provided by the lower part of the wings which provides bearing face at the upper part of the sole. This is also not limiting.

  • the fastener has an elastic return mechanism of the body in position aligned with the vertical and longitudinal median plane defined by the longitudinal direction of the ski.
  • This mechanism comprises in known manner a spring 115 housed in a longitudinal recess of the body which is closed by a threaded plug 116. A end of the spring bears on this plug whose screwing makes it possible to adjust the hardness of the retaining element, that is to say the initial compression of the spring 115.
  • the piston has on its support face two lateral chamfers 118a and 118b, which are slightly inclined. So the face bearing the piston thus has a central face 118c of triangular shape, seen from the front, and two lateral chamfers 118a and 118b.
  • the spring 115 keeps the body in a stable aligned position with the midplane. Under the action of the lateral stresses of the shoe, the jaw and body tend to pivot around either of the support lines pivot 102, against the restoring force developed by the spring. In case of excessive stress, the rotation of the jaw is sufficient to allow the shoe release.
  • the stress threshold beyond which the shoe is released is commonly called the trigger threshold. This threshold depends directly from the nature of the spring and its initial compression. With the elements that have been described so far, the trigger point is about the same for the two directions of pivoting of the body, on one side or the other of the median plane.
  • the retaining element has an adjustment mechanism acting on the threshold for triggering the jaw depending on whether it moves to one side or the other from its aligned position.
  • these means comprise a flat flap 119 which is interposed between the piston 118 and the face 108 of the pivot 104.
  • the piston 118 bears on the face 108 of the pivot 104 by through flap 119.
  • the flap 119 laterally has two beads 120 and 121 whose spacing is substantially equal to the width of the face 108, so as to that in the aligned position, the flap is freely fitted on the face 108 and plated against this face.
  • the flap in its upper part, has a return 122 which maintains the flap vertically by pressing against the piston 118.
  • the bearing surface of the flap 119 on the pivot 104 is wider than the surface of support of piston 118 on flap 119.
  • Means make it possible to control the movement of the shutter, by associating it or either to the pivot, or to the body of the retaining element.
  • the flap has in its upper part a cleat 125 projecting, aligned with the median plane.
  • a movable latch 126, 127 mounted on a transverse joint 128 carried by the body.
  • Each latch is movable between a low position where it blocks the relative movement of the cleat on the side where the latch is located, and a high position where it allows the relative movement of the cleat.
  • An elastic element for example a pin spring 129 recalls each movable latch in high position.
  • An operating button 130 is located above the body in the near the movable end of the latches.
  • the button presents a part accessible from above the hood of the body, it crosses the hood, and presents below a ramp 131 for controlling the position of the latches.
  • the button 130 is movable along a transverse direction. For example, it is guided in a transverse opening of the wall of the body.
  • Ramp 131 has three parts, a horizontal central part 131a, and, on each side of this part central, an inclined part 131b and 131c respectively.
  • the button has three main positions, a middle position substantially aligned on the axis longitudinal median. In this position, the horizontal part 131a immobilizes the two latches in the low position.
  • the flap 119 is subject to the movement of the body.
  • Figure 24 illustrates this mode of operation.
  • the release of the shoe is obtained after a rotation determined angle of the body, for a trigger threshold defined by the compression of the spring 115.
  • the compression of the body is relatively strong. This compression depends on the bearing faces 102 of the pivot and on the surface opposite the flap 119.
  • the button can be moved laterally on either side of this position median. In each of the side positions of the button, one of the latches is released, and goes up under the action of spring 129.
  • the flap 119 For a direction of rotation of the body, the flap 119 remains slaved to the body by the latch which remained at the bottom. For the other direction of rotation, the flap is no longer driven by the latch, and therefore remains in abutment against the face 108 of the pivot.
  • the figure 25 illustrates this operating mode.
  • the release of the shoe is reached for less compression of the spring.
  • the threshold of trigger has been lowered.
  • the button 130 polarizes the element of restraint by modifying its trigger threshold for one of its directions of pivoting.
  • the two inclined parts 131b and 131c of the ramp are used to lower one either of the latches when the button is brought back from a lateral position of polarization in the middle position.
  • buttons maneuver must be adjusted either in the middle position or in symmetrical positions corresponding to a lower trigger threshold for a release of the shoe corresponding to a twist of the leg in the sense where the foot is driven inward.
  • the button 130 can present any suitable means, for example a small bowl 135 intended to receive the tip of the stick.
  • the shoes used with the elements of restraint may have a key point which encourages the adjustment of each of the buttons in the correct position.
  • Figure 26 shows a retainer 141 which is of the same type as that of FIG. 1, with in particular the spring 12, the tie 13, the wall 18, the rocker 25 and ring 24.
  • the difference is that the rotation of ring 24 is driven electrically, not mechanically.
  • the ring 24 is here driven in rotation by an electric motor 142 which drives a toothed wheel 143 whose teeth are engaged on the grooves of the ring.
  • the motor is fixed for example to the wall 18. It is of any suitable type, and for example, it is provided for example to rotate with a pitch corresponding to a quarter turn of the wheel toothed.
  • the rotation of the motor is controlled by a switch whose part mobile has three stable positions, and is at least partially accessible from the outside, for example above the cover of the retaining element.
  • Such switch is represented in figure 27 under the reference 145.
  • This switch has a body 146 which is fixed to the cover of the retaining element, and a part mobile 147 which is oriented in a transverse direction, and articulated around of a longitudinal axis. Above the cover, the movable part has two faces in open "V" shape.
  • Figure 28 shows the moving part in its middle position, which corresponds to the middle position of the ring.
  • Figure 29 shows the moving part in one of its stable positions side. This position is for example imposed by pressing on one of the faces of the mobile part, by means of the stick. In this position, the switch controls rotation of the motor 142 to rotate the ring 24 towards the position of polarization assigned to it. The position of the moving part of the switch is also indicative of the polarization of the retaining element. In others terms, depending on which side of the switch is pressed toward the hood, it is possible to see if the retaining element is polarized as a straight element or as left element.
  • the switch 145 and the motor are coupled by electrical means, including a battery and connectors. These means are of a known type and will not be described in detail.
  • the present description is not limited to the different modes and variant embodiments which have been described, and many variants are possible.
  • the invention can be adapted to other constructions known restraint than those which have been described.
  • the operating buttons could be placed in front of the retainer, on the side, or in any other area appropriate.
