Definitions

  • the invention relates to safety bindings for skiing, and in particular the mounting of the stop before a binding on a ski intended for the practice of hiking.
  • a ski is usually provided with safety fasteners allowing the transmission of forces between the shoe of the user and the ski.
  • the safety bindings generally have a front stop ensuring the support of the boot during the use of the ski.
  • the front stops are generally designed to release the shoe when excessive transverse force is applied by the shoe.
  • This safety binding consists of a plate carrying the boot, pivotally mounted relative to a front base fixed to the ski, and provided at the rear with detachable connecting means to the ski.
  • the connecting means at the rear of the plate selectively mate with a rear base fixed to the ski.
  • This safety binding is intended for use with rigid alpine ski boots or hiking boots that are locked on the pivoting plate.
  • a front stop and a heel are attached to this plate to ensure the maintenance of the shoe or heaving if necessary.
  • the pivoting plate In the up position, the pivoting plate is released from the rear base so as to allow pivoting of the boot relative to the ski.
  • the pivoting plate In the downhill position, the pivoting plate is coupled to the rear base so as to allow the practice of skiing according to alpine descent techniques.
  • skis and safety bindings are sent to points of sale by the manufacturer.
  • Most legislations and manufacturers now require the fitting of ski bindings by the point of sale and not the end customer. This guarantees a careful installation and complies with the manufacturer's instructions. Thus, it limits the risk of improper mounting of the fasteners, which could lead to a tearing of the binding and a serious fall of the user. This limits the risks of having the manufacturer liable in the event of an accident for a mounting fault.
  • the plate carrying the attachment is relatively long and has a significant overhang relative to the front base.
  • the distance between the pivot axis of the plate and the coupling area of the plate to the rear base is relatively large.
  • the front base and the rear base are attached to the ski through self-drilling screws penetrating into a reinforced part of the ski.
  • An angular positioning defect of the front base relative to the axis of the ski induces a large transverse offset of the rear end of the plate relative to its attachment area to the rear base.
  • this position can no longer be corrected once the tapping of the skis by the screws has been initiated.
  • Fastener manufacturers generally provide the points of sale with templates to define the relative positioning of the front and rear bases on the ski.
  • templates do not completely eliminate positioning errors self-drilling screws and do not correct such errors. Indeed, once a screw has initiated a tapping in the ski, it can no longer screw the same screw in the immediate vicinity of this tapping without risk to the strength of the mechanical connection.
  • the components of the fasteners are made with reduced manufacturing tolerances to limit the positioning dispersions. Such tolerances unfortunately induce a significant additional cost of fixing.
  • the front stops and the bases before the commercial security fasteners generally have too much axial space. In practice, this axial size limits the pivoting stroke of the plate forward, which can be detrimental to the performance of the user.
  • the invention aims to solve one or more of these disadvantages.
  • the invention proposes that the front base of a safety attachment has a fixing wall coming opposite the ski. Bores are formed in this wall. At least one of these bores has an oblong shape so that the front base has a pivoting stroke about a direction normal to the ski when self-drilling screws are partially screwed into the ski through said bores and so that the front base is immobilized relative to the ski when the self-drilling screws are tightened.
  • the invention makes it possible to dispense with templates for positioning the safety binding 1 relative to the ski.
  • the errors of positioning of the screws with respect to the ski can easily be corrected, which allows a correct coupling of the plate with the rear base (it thus avoids forcing and deteriorating the binding during a passage in the down position) and which avoids scrapping skis for incorrect placement of the screws.
  • less stringent manufacturing tolerances of the components of the fastener 1 can be used without impairing the quality of its assembly.
  • the figure 1 is a side view of a safety attachment 1 in which a shoe 6 is mounted.
  • the figure 2 is a perspective view of this fixation, in the lack of the shoe 6. For legibility, neither the heel or the rear base of the attachment 1 have been illustrated.
  • the illustrated attachment 1 belongs to a mixed-use safety binding, that is to say to selectively practice downhill skiing or ski touring.
  • the attachment 1 comprises a front base intended to be fixed rigidly to a ski (not shown).
  • the front base of this embodiment comprises first and second parts 400 and 700.
  • a front stop comprising a connecting member 300 and a body 200, is pivotally mounted relative to the first part 400 about a transverse axis.
  • the first part 400 comprises a stirrup 401 extending vertically.
  • a shaft 502 joins two faces of the bracket 401 vis-à-vis, at its upper part. The shaft 502 passes through a bore of the junction member 300 to allow it to be rotated relative to the first portion 400.
  • junction member 300 and the body 200 are rigidly connected.
  • the body 200 is pivotally mounted relative to the first portion 400 through the junction member 300.
  • the body 200 defines the axial position of the boot 6 with respect to the ski.
  • the body 200 (shown in section) also comprises a flange 202 disposed in line with a protuberance 62 formed in the sole 61 of the boot 6, when the latter is held by the fastener 1.
  • the connecting member 300 comprises a support 301 for the lower part of the sole 61 of the boot 6. A vertical support of the boot 6 is thus ensured.
  • the spacing between the flange 202 and the sole support 301 substantially corresponds to the distance between the upper portion of the protuberance 62 and the bottom of the sole 61, with a close game. This distance is standardized, both for an alpine ski boot and for a hiking boot.
  • the spacing between the flange 202 and the sole support 301 corresponds to an alpine ski boot.
  • This spacing may be adjustable by any appropriate means to be able to alternately use the safety binding 1 either with an alpine ski boot or with a ski touring boot.
  • the connecting member 300 further has in its rear part a connecting member 303 between the front stop and a not shown heel.
  • the heel piece makes it possible to maintain a rear protrusion 63 of the sole 61.
  • the heel piece In alpine skiing mode, the heel piece is coupled to an unillustrated rear base fixed to the ski, thus preventing the body 200 from pivoting relative to the first part 400.
  • ski touring mode the heel is uncoupled from the ski, thereby pivoting the body 200 relative to the first portion 400. The heel of the user can be removed from the ski to allow pivoting of the foot.
  • the front stop and the heel can be designed to release the foot of the user when excessive efforts are exerted.
  • the front stop may include a mechanism known in itself releasing the foot when excessive transverse force is applied, while the heel may include a mechanism known per se freeing the foot when excessive vertical force is applied.
  • the first part 400 has a rotation stroke relative to the normal to the ski, when its fixing screws are partially screwed into the ski but they are not yet tightened.
  • the rotational stroke of the first portion 400 can then advantageously be between 2 and 15 ° under these conditions, preferably between 3 and 10 °.
  • the second portion 700 of the front base is intended to be fixed to the ski by self-drilling screws.
  • the first portion 400 is slidably mounted in the second portion 700.
  • a transverse clearance is formed between the second portion 700 and the first portion 400 so as to be able to slightly pivot the first portion 400 when the second portion 700 is fixed and immobilized relative to the ski.
  • the figure 3 illustrates the first part 400 and the second part 700 before assembly.
  • the first portion 400 has a wall 408 whose lower face has a rear portion intended to come into contact with the ski.
  • Oblong through orifices 406 and 407 are formed in the rear portion of the wall 408. These oblong orifices 406 and 407 are intended to be traversed by the body of self-drilling screws not shown.
  • the oblong shapes of the orifices 406 and 407 have an elongate shape in the direction transverse to the ski.
  • the stirrup 401 extends vertically from the upper face of the wall 408.
  • the stirrup 401 has in its upper part through holes 410 and 411 forming a bearing for the shaft 502.
  • a shoulder 409 is formed between the front portion and the rear portion of the wall 408.
  • the rear portion is thus lower than the front portion of the wall 408.
  • the tenons 402 and 403 extend transversely outwardly from the front portion of the wall 408.
  • Grooves 404 and 405 extend axially from the front end of the wall 408.
  • the shoulder 409 forms an axial stop for the second portion 700.
  • the shoulder 409 is advantageously shaped so that the lower face of the rear portion of the wall 408 is flush with the underside of the second portion 700.
  • the support of the front base on the ski is optimal.
  • the second portion 700 has guide rails 703 and 704 on its transverse edges.
  • the rails 703 and 704 are shaped to receive the tenons 402 and 403 and guide them in axial sliding.
  • the tenons 402 and 403 are inserted into the rails 703 and 704 until the second portion 700 abuts with the shoulder 409.
  • the bores 701 and 702 are then disposed vertically above the grooves 404 and 405.
  • the heads self-drilling screws 8 solidarisant the second part 700 to the ski are then housed in the grooves 404 and 405, as shown in FIG. figure 6 .
  • the orifices 406 and 407 are accessible to the user when the front stop is pivoted forwards, as illustrated in FIG. figure 7 .
  • self-drilling screws can be put in place, be screwed into the ski without tightening to proceed to the angular positioning of the first portion 400, and then tightened to immobilize the angular position of the first portion 400 relative to the ski.
  • the rails 703 and 704 then make it possible to transmit forces along all the axes between the first part 400 and the ski via the second part 700.
  • the rear base When mounting the attachment 1, its rear base will be advantageously positioned on the ski beforehand. Once properly positioned, the rear base is secured to the ski by means of self-drilling screws in a manner known per se.
  • the second part 700 is then positioned on the ski, then immobilized at the right position by means of self-drilling screws 8 passing through the bores 701 and 702.
  • the first part 400 (integral with the fore / heel stop assembly) is positioned relative to the second portion 700, inserting the lugs 402 and 403 in the rails 703 and 704.
  • the first portion 400 is axially slid until its shoulder 409 abuts against the second portion 700. Auto screws -forants are then arranged through the orifices 406 and 407.
  • the first portion 400 can rotate over a certain stroke about an axis normal to the ski plane.
  • the fitter can then test if the heel is correctly positioned relative to the rear base. If this is not the case, the fitter refines this positioning by pivoting the first part 400. When a satisfactory adjustment is obtained, the fitter proceeds to tighten the self-drilling screws passing through the bores 406 and 407 until the first part 400 is completely immobilized with respect to the ski.
  • the bores 701 and 702 are disposed substantially vertically above the body 200, and preferably at the base of the shaft 502.
  • the fixation 1 coupled to the ski it has no component that can interfere with the forward pivoting of the body 200.
  • the pivoting stroke of the body 200 is increased, which allows the user to give a greater amplitude to its movements in climb position.
  • the front base then has a particularly small axial size.
  • the embodiment illustrated in Figures 1 to 7 therefore allows to pivot the first part 400 relative to the normal to the ski after initiating the screwing of its self-drilling screws but before having completed their tightening.
  • the pivoting adjustment is allowed by the combination of a transverse clearance and a sliding of self-drilling screws in the oblong holes.
  • the second portion 700 can be pivotally mounted relative to the normal to the ski through a single bore 706 traversed by a self-drilling screw.
  • the pivoting guide before clamping can then be provided by the combination of the screw passing through the bore 706 (forming a pivot) and screws passing through the oblong holes 406 and 407 of the first part 400.
  • a very small transverse clearance is also provided between the second portion 700 and the first portion 400.
  • a single circular orifice 412 is formed in the first portion 400 and oblong bores 701 and 702 are formed in the second portion 700.
  • the pivoting can be performed around the screw passing through the orifice 412 (forming a pivot), the rotational guiding also being ensured by means of the screws passing through the oblong bores 701 and 702 of the second part 700.
