Definitions

  • This invention relates to a ski binding particularly for cross-country skiing.
  • ski bindings for such an application generally comprise a ferrule which is secured directly on the ski body and adapted to receive an engaging device carried on the toe end of the ski boot to provide releasable engagement between the ferrule and boot, thereby enabling connection of the ski to the skier's foot.
  • Such prior ski bindings generally include shoe engaging members mounted on elastic blades, which involves shifting of the boot point of attachment to the ski, thus adversely affecting directional control of the latter and resulting in a proportion of flex being entrusted to the sole of the boot, which can no longer be formed with stiffening ribs to ensure resistance against torsional stresses.
  • Conventional ski bindings usually comprise an either permanently or removably attached elastic pad which is sufficiently rigid to enable ski control by the skier, but involves a continued effort by the skier in his/her stride.
  • ski bindings generally lack self-lubricating features and require as a result regular maintenance, which when not carried out periodically, can adversely affect the correct operation of the bindings.
  • the task of this invention is to obviate such prior problems by providing a ski binding particularly for cross-country skiing, which can significantly attenuate a skier's toil, while enabling him/her to retain complete control on the skis during effectuation of the skiing stride.
  • a ski binding which includes an elastic pad adapted to bias the ski to its normal position, that is, to a constantly parallel position to the skier's boot.
  • Still another object of this invention is to provide a ski binding which can perform correctly at all times by virtue of its self-lubricating, antifreeze, and ice-breaking features.
  • a ski binding particularly for cross-country skiing characterized in that it comprises a ferrule slidably associated, against the bias of an elastic means, with a fastening element to the ski, said fastening element having substantially orthogonal sides to its mounting plane and a means of guiding said ferrule in its sliding movement parallel to said mounting plane.
  • a ski binding according to the invention is generally designated with the reference numeral 1, and comprises essentially a fastening element 2 to be mounted on the body of a ski, not shown in the drawing, which has a ferrule 3 slidably associated therewith against the bias of an elastic means 5 including two rubber bands 4.
  • the fastening element 2 has on each of its sides 6, which are substantially orthogonal to the mounting plane 7 thereof, a guide means 60 for guiding the ferrule sliding movement parallely to said mounting plane.
  • the guide means comprises a wing extension 8 advantageously cooperating with at least one guide element 9 which includes a peg 10 carried orthogonally on the sides 6 and engaging at its end portions in two slots 12 formed through the sides 6 of the fastening element 2 and in two holes 13, formed each through the ferrule 3i
  • the rubber bands 4, in particular, are held in a biassed condition inside the ski binding by the peg 10 and by a rod 14 spaced in a parallel relationship from the peg 10 and engaging in two holes 15 as formed on the sides 6.
  • the sides 6 are each provided with a groove 16 adjacent to the wing 8 and configured to securely receive the ends of a metal insert 17 which protrude laterally from the toe end of a sole of a boot 18.
  • the grooves 16 may also have configurations other than the round one, for example, as shown in Figures 10 to 13 where substantially quadrangular configurations are illustrated which, by engaging with a metal insert mounted at the boot toe end and having a complementary shape, will inhibit relative rotation between the binding and boot and only serve the function of making the latter rigid with the ski, allocating an amount of flex during the skier's stride to the sole of the boot itself.
  • the ferrule 3 has a pair of arms 19 pointing in the same direction and extending respectively adjacent to the sides 6 for sliding movement therealong, which arms comprise each one surface portion 20, at the ferrule facing end, advantageously configured to engage with a snap-in action with a respective one of the grooves 16 to define an engagement seat 22 for the end of the metal insert 17.
  • Each wing extension 8 is formed, on the side facing the ferrule, with a bevel 23 which defines, together with the inclined surface 24 of each arm 19, a lead-in region effective to favor the introduction of the metal insert 17 into the seat 22, thanks to said insert generating a sliding action between the fastening element 2 and ferrule 3 against the bias of the two rubber bands 4.
  • the wing extensions 8 allow for a sliding movement, along the sides 6, of the two arms 19, while holding them securely and cooperating with the guide element 9 to prevent them from moving, together with the ferrule as a whole, upwardly with respect to the fastening element 2.
  • the sides in combination with the mounting surface 2, define a seat 25 adapted to accommodate a small elastic block 50, preferably made of rubber, which engages releasably in the seat 25 and can be readily replaced with other elastic blocks from a range having advantageously different elastic characteristics according to the ski weight, thereby to bias it to a parallel position to the boot at the end of each stride by the skier and enable the latter to ski with less effort.
  • a small elastic block 50 preferably made of rubber
  • the block 50 engages on the rod 14 to form an elastic reaction device between the toe end of the boot sole and a wall 26 fastened to the surface 7 and eliminate any play between the boot and binding. This may be accomplished, for example, by interposing between two sides of said block, presenting a longitudinal groove therebetween, an adjustment screw which, as a function of the extent of its penetration into the groove, enables the two sides to be moved to and away from each other so as to take up any play which may have developed between the boot toe end and binding, even after prolonged operation of the block.
  • the block allows, in the course of the skier's stride, the metal insert held in the seat 22 to originate a force tending to cause the ferrule to slide relatively to the fastening element and prevent formation of ice therebetween while permitting self- lubrication of the entire binding; this movement enables, moreover, the two wings 8 to eject from the arms 19 any snow in skiing, thus ensuring at all times optimum working conditions for the binding as the boot is pivoted about its hinge axis.
  • the ferrule 3 has the surface portion 27, remote from the arms 19, advantageously formed with a point, and precisely, formed with its two side surfaces slightly inclined and converging toward an apex, and defining with the latter a downward sloping top surface which encourage snow to slip off the ferrule while skiing. Furthermore, the ferrule, during its back and forward movement relatively to the fastening element 2 rigid with the ski body, will break, and hence remove, any ice formation which may have built up on the binding front in skiing.
  • the ferrule 3 has on each side at least one dimple 28 which facilitates, when necessary, manual displacement of the ferrule relatively to the fastening element.
  • the ferrule 3 is provided at the top with a small cover plate 29 having a recess 30 suitably shaped to engage with the tip 32 of.a ski pole, not shown in the drawing, in order to avoid the need for the skier to bend forward, when releasing the binding, to apply the required pressure for sliding the ferrule.
  • a depressed surface 33 of arrow-like configuration for leading the tip 32 of the ski pole into the recess 30 and visually indicating the direction in which the ferrule is being moved relatively to the fastening element.
  • a further embodiment of the cover plate 29 provides for the elimination of the recess 30 therefrom, in which the tip 32 of the ski pole engaged, so that the binding is now released by applying, either manually or through the tip of any small stick, a pressure to the plate 29, which on being depressed will allow the ferrule 3 to slide relatively to the fastening element 2.
  • Another embodiment would provide for the binding to be released by means of a lever pivoted eccentrically on the ferrule which, when rotated, moves the ferrule relatively to the fastening element 2 and disengages the boot from the binding.
  • the fastening element is provided at the bottom, adjacently to the ski body, with a plate 34 which, in combination with the fastening element itself, defines a fairing effective to prevent snow and water from seeping into the binding.
  • the closure plate 34 extends along the ski body and has, at a middle position thereof, two large longitudinal ribs 35 which engage releasably in two corresponding grooves provided on the boot sole to perform a ski banking prevention function, thereby the skier can constantly exert proper directional control of the ski without requiring any additional means on the bindings.
  • the closure plate 34 is suitably configured to also serve the function of a template, it being provided with a balance line 60 to facilitate drilling of the holes in the ski body for engagement by the mounting screws of the fastening element 2.
  • the ski binding may be configured as shown in Figure 9, and comprises a ferrule 113 slidably associated against or with the bias of an elastic means, specifically a spring 122, with a fastening element 111.
  • the sides 110a and 110b are each formed with respective grooves 109a and 109b, and substantially orthogonal to a mounting plane 112 and parallel to each other to define a seat 113 accommodating the boot block whereacross a pin having free ends is passed.
  • a guide means adapted to allow the ferrule to be moved substantially parallel to the mounting plane.
  • the guide means preferably comprises first and second pegs, respectively indicated at 118 and 119, carried orthogonally on the sides, which engage with slots 120 and 121, respectively, provided the former on the arms 115a and 115b., and the latter on the snap-action body.
  • the coil spring 122 is located between the fastening element and ferrule to hold the seats 116 in a condition of interaction with the grooves, so as to allow for the snap-action engagement of the free ends of the pin.
  • the spring 122 is inserted into a cavity 123, wherein there engages a screw adjustment element 124 to change the spring load, the spring acting against the pin 119 to adjust the binding release force.
  • the sides have at their rear ends, that is the ends next to the boot, enlarged portions defining corresponding guide butts, 125a and 125b, which act laterally on the boot block and cooperate in preventing the boot from leaning out relatively to the ski.
  • top ends of the butts 125a and 125b have, on the remote side from the mounting plane and at each groove, a bevel 126 which, in cooperation with a similar bevel 127 at the end of each arm, causes, upon the free ends of the pin being pressed thereon, disengagement of the arms from the grooves, thus enabling snap-action engagement of the pin.
  • the seat accommodates an elastic pad 128, preferably made of rubber, which releasably engages with the seat to be readily replaceable with other like pads having different elastic properties according to the skill and weight of the skier, as well as to the preformance expected of the bindings.
  • an elastic pad 128, preferably made of rubber which releasably engages with the seat to be readily replaceable with other like pads having different elastic properties according to the skill and weight of the skier, as well as to the preformance expected of the bindings.
  • the pad 128 can have seating regions for the guide means in the form of a bore 129 therethrough.
  • the pad is interposed directly to form an elastic reaction device between a front wall of the block and a crosspiece or bridge 132 attached to the surface 112 to oppose movements of the pad as the latter is compressed by the block by the boot rotating about the axis of the pin embedded therein.
  • the crosspiece is perforated to facilitate adjustment of the device 124; it should be further noted that the snap-action body has, at the remote end from the ski, a pressure region 135 provided with a means promoting the grip on the snap-action device, such as crosswise extending grooves, knurled surfaces, and the like, and formed at an intermediate portion thereof is a recess 136 adapted to engage with the tip of a ski pole, not shown, to prevent the skier's need, on releasing the binding, for bending and exerting the required pressure to slide the snap-action device.
  • a pressure region 135 provided with a means promoting the grip on the snap-action device, such as crosswise extending grooves, knurled surfaces, and the like, and formed at an intermediate portion thereof is a recess 136 adapted to engage with the tip of a ski pole, not shown, to prevent the skier's need, on releasing the binding, for bending and exerting the required pressure to slide the snap-action device.
  • the bias applied by the elastic bands 4 will return the ferrule to its original position, thereby locking the pin in the position reached while holding it in pivotal or fixed engagement with the binding.
  • a further advantage of the inventive binding is that by providing the closure plate below the binding, any water or snow seepage into the binding can be prevented, thus achieving good efficiency and prevention of likely jamming conditions due to the formation of ice between mutually moving parts.
  • the two elastic bands 4 may be connected directly to one portion of the elastic block, as shown in Figure 4, so as to eliminate, for example, the holding rod 14.
