Definitions

  • the present invention relates. to skis and has as its obl'ect the provision ofparticularly shaped retaining teeth on the sliding sole of the ski to prevent backwards lsliding of the 'ski on a ⁇ 'i slope but which do not interfere with the forward movement of the ski.
  • the teeth are obtained by providing in the sole surface series of recesses extending in directions which are inl ouned relativo to the longitudinal axis of the ski. and one series of recesses being oppositely inclined relative to another series, sol that the recesses of two series intersect 'each other once at least on one half of the widthjof the ski sole.
  • the accompanying drawing represents by way of example 4various forms of embodiment of the subject of the invention.
  • Figure 1 is a fragmentary view of the nrst form in plane from below;
  • Figure .2 is a section 'along the line 1 2, and
  • Figure 3 is a section alongthelinel--lof Fig. l.
  • Fig. 4 is a view of the second form in plan from below;
  • Fig. 5 is a section along the line i-l of Fig. 4.
  • Fig. 6 is a similar plan view of a thirdform;
  • Figures 7 and 8 are sections along the lines 1--1 and I-l, respectively, of Fig. 6, drawn to a greater scale.
  • u Fig. 9 is a plan view of a fourth form of embodiment.
  • the ski according to Fig. 1 comprises a body I of wood to which is secured a layer I forming the sole of the ski and consisting of a material u which is harder than woodvand to which the snowdoesnot stick, such as for example celluloid.
  • the sole face of the ski is suitably recessed to provide ratchet teeth la and 4b for the purpose of preventing the ski from sliding u backwards, and such teeth are cut on yboth sides of the longitudinal central groove 3 of the sole.
  • Bach tooth has an inclined face 5 and a retaining face l. 0n each'of the two halves of the sole face, separated by the groove l, are cut two 'series of teeth which are inclined in opposite directions relative to the longitudinal axis of vthe ski.
  • the two branches of the herring-bone teeth formwith the longitudinal axis of the ski angles vof about ilfteen degrees. This angle may vary and may be between ten and forty degrees. 'Ihe apices' of the herring-bone .teeth are ldirected I towards the ⁇ front of the ski and the retaining faces I of the teethA are directed towards the back. Owing tol the inclination of the teeth relative'to thev longitudinal direction,'the gradient of the frontface l of the teeth is much smaller l0 in longitudinal section as seen in Fig. 3 than in transverse section as seen in Figure 2. faces provide only a small resistance against vthe advancement of the Upon a backward effort thesnow is pushed towards the apices of u the Vherring-bone teeth, where it is compressed without being capable of moving away.
  • two series of herring-bone teeth are provided on either side ofthe groove i.
  • the heightof the holding faces i of the teeth is constant from the apice of a herring-bone tooth over the major part of the length oi' a branch of a herring-bone tooth and then itgradually decreases over the remaining-part until the face I disappears at a point where there abuts a secondary edge 9a marking the intersection of the lower surface of the sole with the face S ofthe 35 contiguous tooth at the back.
  • the median groove l could be omitted and replaced by a -flfth row of herring-bone teeth as shown in Figure 11.
  • the rows of herring-bone teeth are separated o from the edges of the ski by portions of smooth surfaces i9 which are not toothed, and are also separated one from the other by such surfaces, in the represented examples.
  • the fact that the edges do not present toothings permits the pro 5 vision of reinforcement borders ⁇ of any known type.
  • 'I'he toothing of the sole surface can be obtained by pressing, rolling, casting or cutting.
  • a ski having its lower surface provided with a layer of sliding material, retaining teeth provided in said sliding material for preventing ⁇ backwards sliding of the ski, said teeth being formed by a plurality of longitudinally arranged series of recesses having the shape of-v herringbones, the apices of the herring-bones being situated on a longitudinal line, and the depth of the recesses being constant over a portion of the length of the herring-bones and then gradually ⁇ decreases over the remaining portion ofthe length.
  • a ski having its lower surface provided with a layer of sliding material, retaining teeth provided in said sliding material forlpreventing backwards sliding ofthe ski, said teeth being formed by a plurality of longitudinally arranged series,l
  • the apices of the herring-bones of each series being situated on a longitudinal line, the branches of the herring-bones forming angles between ten and forty degrees with the longitudinal axis, and the depth of the recesses being constant over a portion of the length of the herring-bones beginning at the apice thereof, and then gradually decreases over the remaining portion of the length.
  • a ski having its lower surface provided with a layer of sliding material, retaining teeth provided in said sliding material for preventing backwards sliding of the ski, said teeth being formed by a plurality of longitudinally arranged series of recesses having the shape of herring-bones, the apices of the herring-bones of each series being situated on a longitudinal line. the branches of the herring-bones forming angles between ten and forty degrees with the longitudinal axis, said sliding surface comprising smooth surface 'portions separating adjacent series of retaining teeth, and smooth surface portions separating the outermost series of teeth from the lateral edges of the sliding surface.
