Definitions

  • the invention relates to an anti-recoil device for skiing which, by immobilizing the ski with respect to the snow or the underlying ice, allows the user to move the other ski to climb a slope.
  • a ski braking device comprising two levers arranged on either side of the ski and articulated around a transverse axis so as to occupy an inactive position in which their useful parts are above the ski and an active position in which these levers extend obliquely towards the rear and below the ski.
  • This device ensures braking on the descent and prevents transverse skidding on the ascent but is not able to prevent the ski from rolling back.
  • devices comprising lateral braking arms retracting on the top of the ski in the inactive position. These lateral arms are constantly returned to the active position, in which they extend obliquely rearwards below the ski, by spring means countered by the support of the sole of the skier's shoe.
  • these latter devices can only brake and stop the sliding movement of the only ski on which they are mounted and are therefore not able to prevent it from rolling back when this ski is linked to the skier. Indeed, under these conditions, the connection of the boot with the ski erases the braking arms which, in any case, are not designed to withstand the mechanical force generated by the temporary blocking of the skier, effort exerted in the direction of the front, therefore in the opposite direction to the effort resulting from the braking of the single ski.
  • the object of the present invention is to provide a very effective anti-recoil device, insensitive to variations in the condition of slippery surfaces, erasable, resistant and operating only on the request of the skier.
  • This device of the type which is fixed outside the bearing area of the sole of the boot, comprises a flap articulated on the ski around a transverse axis and two lateral arms each composed, on the one hand, of a part front in the form of a pin mounted freely in rotation in the flap, about an axis disposed in a longitudinal plane, on the other hand, of an intermediate part substantially perpendicular to the pin and having a lower bearing face capable of coming onto the ski, and, in addition, a rear part, constituting a crampon and a support member on the rear while the flap is associated with means tending to bring the arms into the active position and with means independent of the skier. wedging in a position corresponding to that of erasure of these arms.
  • the device in the inactive position, the device is locked with its arms arranged above the ski and in the direction of the rear thereof. To bring it into the active position, it suffices to actuate the wedging means of the device so as to release these arms which, at first, pivot laterally on either side of the ski relative to the flap, then, in a second time, pivot at the same time as the flap so that the end of their rear part constituting a crampon comes into contact with the underlying snow or ice.
  • the anti-recoil device of the ski in support receives all the reaction of the effort of advancing the other ski and pivots relative to the ski until the intermediate parts of the lateral arms come into contact with the ski and transmit to the latter part of the resistant force which, otherwise, would risk damaging the device or its articulation mechanism.
  • the anti-recoil device is resistant and can be successfully used to climb steep slopes. declivity.
  • the rear part of each of the arms is in the form of a curved pallet while the intermediate part is constituted by a plate in the form of a right triangle which, integral in its angles, other than that of the right, respectively of the front journal and of said rear curved pallet, has a flat rear face capable of bearing on the ski when the arm is in the active position.
  • the flat faces of the intermediate parts increase the contact surfaces between the ski and the arms, improve the bracing of the arms on the ski and contribute to reducing the wear of the anti-recoil device.
  • the device according to the invention is essentially constituted by two lateral arms (2) mounted pivoting about longitudinal axes (x'-x) in a flap, generally designated by (3), itself articulated around a transverse axis (z'-z) by relative to a fixing sole (4) linked to the sole (5) of the ski.
  • the flap (3) consists of a piece in the shape of a "U", each of the wings (3a) of which is crossed by right through by a bore (6) constituting a bearing for the pin (7) of the corresponding side arm (2).
  • These two wings (3a) are also crossed by aligned transverse bores (8) capable of receiving a transverse articulation axis (9), visible in FIG. 2.
  • a tenon (10) projecting vertically from the support sole (4) and having the shape of a yoke whose wings are crossed by transverse bores (12) capable of receiving the axis (9).
  • the pin (7) constituting the front part of each of the lateral arms is connected by an intermediate part (15) to a rear part in the form of a curved pallet (16).
  • the intermediate part (15) of each of the arms (2) consists of a plate in the shape of a right triangle which is secured by its two non-right angles, respectively, to the front pin (7) and to the rear curved pallet .
  • This plate has a flat lower face (15a) whose usefulness will be specified below.
  • the curved pallet (16) has, on the one hand, in its part which is anterior when it is in the position of use, a convex face (16a) and, on the other hand, on its back, a concave profile ( 16b). At its end, this pallet is provided with a penetration spout (18) which is inclined on the front with respect to it and the end edge of which is provided with teeth (19).
  • each pin (7) is provided with means linking them in rotation to the oscillations of the second flap (14) -
  • the free end of each pin (7) projecting from the front part of the first flap (3) is integral a radial lug (20), turned towards the inside of the ski and penetrating into a fork (22) projecting vertically downwards from the second flap (14) as shown in FIG. 2.
  • the free end of each lug thus being trapped between the two stops of the corresponding fork (22), it is easily understood that any movement of the second flap (14) controls the pivoting of the lateral arms (2).
  • the anti-recoil device also comprises return means tending to return the arms (2) to the active position and means wedging the flap (3) in the position for erasing the arms (2).
  • the shutter locking means (3) consist of a locking member secured to the second shutter (14) and in particular by the notched edge (23) of a rib (24) projecting from the underside of this flap. This notched edge snaps onto an elastically erasable complementary member also constituting the unlocking member. In this embodiment, it engages with the front edge (25a) of a flexion loop (25) articulated on the sole (4).
  • the posterior ends of this loop in a direction substantially parallel to its anterior edge (25a), penetrate into a housing (21) formed in the sole (4) in front of the bores (12) for the articulation of the first and second shutters.
  • the lateral branches of the loop (25) are integral with a pallet (26) for controlling the unlocking.
  • the second flap (14) is snapped into place with the flexion loop (25) and forces the first flap (3) to occupy a position slightly inclined to the horizontal.
  • the lugs (20), for controlling the lateral arms (2) are substantially horizontal and the lateral arms (2) are arranged above the ski (5) and pivoted towards each other so that their concave faces are opposite as shown in FIG. 1.
  • FIG. 5 shows that, under these conditions, none of the elements of the device projects laterally from the ski (5).
  • the concave faces (16b) of its curved arms favor the compaction of the snow and thus improve the braking of any recoil.
  • the pallets (16) tend more easily to tilt upwards to reduce their friction on the snow. It is moreover to reduce this friction that they also have a convex anterior face.
  • the lugs (20) and the forks (22) ensuring the transmission of movement from the second flap (14) to the lateral arms (2) are replaced by two sockets which, wedged at the ends of the pins ( 7) are connected by a flexible transverse cable able to cooperate with a single fork or other equivalent member carried by the second flap.
  • the anti-recoil device shown in FIGS. 10 and 11 is simplified compared to that described above so as to be lightened without losing efficiency.
  • this device comprises lateral arms (2) identical to those described in the previous embodiment but whose pins (7) are mounted free in rotation in bearings (40) projecting below a single flap (3) articulated around a transverse axis (9). This axis is carried by bearings not shown, integral with a fixing sole (4).
  • the lateral arms (2) being free to rotate in the bearings (40), their pivoting around the longitudinal axes (x'-x) is ensured individually and manually. It should be noted that, when the lateral arms are brought into the erasing position above the ski, they constitute, by their free ends, wedging means in the erasing position of the device since these ends limit the tilting of the flap (3) .
  • Each of the devices which has just been described can be used alone on a ski, and in this case be arranged, at the rear or at the front relative to the support zone of the boot, or be used with a identical device placed on another part of the same ski.
  • at least the outer pallet receives a removable flap increasing its support surface.
