  • WEARING EDGE FOR sxzs Filed July 15, 194e NARVE BONNA lless may be -made Awithout interstices.
  • ⁇ It isknownfto. provide skis with wear resisting edges, using fastening pieces on which the wearing edge ts slideably'with a- T-shaped', trapezoid- .shaped cr :similarly shaped vdovetail groove in order that the wearing edge shall have a certain possibility .of .longitudinal movement relative to the ski, so'that it does not reduce the flexibility of the ski to a substantial degree and nevertheit has proveddiflicult -to-mountlthe wearing'edge by sliding the same onto the Yfastening Apieces which have beenscrewed onto the ski, without a foregoing division of the edgebecause due to the vertical curvature of the ski Aand especially the usual lateral curvature of the (sides of the ski, the pushing on ofthe wearing edge encounters -a considerable andcontinuouslyincreasing frictional resistance, even if the Afastening pieces have been placed with great care, and as it is necessary to beat the outer end of the wearing edge, which projects
  • acu cording Vto the present invention which consists in that the fastening pieces are at rst inserted into the wearing edge and thereafter xed to the ski by hammering.
  • a wearing edge mounted in this manner has proved entirely satisfactory in use, because although an insertion by beating at the end of the wearing edge is very much hampered by the frictional resistance between wearing edgeand fastening pieces, the resistance is not so great as to aifect the exing of the ski in a vertical plane in the mounted condition of the wearing edge.
  • the fastening pieces may have one or more integral nails; ⁇ most conveniently they are according to the invention made substantially U-shaped, they being formed with an upright nail in either end of an elongated portion with dovetail-shaned cross section.
  • Fig. l k' is a ,lateral view of part "of za wearing edge cf metal with fastening-pieces-insertedfand Fig. 2 is across sectional view :of'theedge ⁇ and a fastening piece at an enlarged scale.

  • Fig. -4 is a side viewof la modified 44formof fastening piece on an enlargedfscale.
  • Fig. 5 is a bottom view, in small scale, of a yski with. wearing yedges -in accordance with ⁇ the invention mounted thereon.
  • Fig. 6 is a side view, in small scale, of the same skiV shown in Fig. 5 with wearing edges mounted thereon.
  • Fig. '7 is a side view of the rear end portion of a ski, this view being in longitudinal cross-section and taken along the line 'l-l' of Fig. 5.
  • Fig. 8 is a view in longitudinal section of an intermediate portion of a ski, taken along the line 8 8 of Fig. 5.
  • the metal edge I has a dovetail-shaped longitudinal groove 2 in the upper surface.
  • fastening pieces 3 are inserted, which are substantially in the shape of a U, the rectilinear central portion 4 of which has a cross section corresponding to the groove 2 and is inserted into the same, whereas the end portions 5 project upward at a right angle and are formed as nails suited for being hammered into the ski.
  • the nails may be formed with barbs, as shown.
  • the metal edge I may in a known manner be continuous or divided into shorter pieces, each of which may be provided with a suitable number of fastening pieces and besides be fixed immovably to the ski at one spot, for instance in the middle or in the forward end if desired.
  • the y length of the nails 5 may be adapted so that they do not wholly penetrate through the ski; they may, if desired, be of varying length in the various fastening pieces corresponding to the varying thickness of the ski. Or the nails mayprotrude through the ski at least in the thinnest portions of the latter and be cut olf, bent or riveted on the upper side of the ski.
  • the fastening piece 3' which is also substantially in the shape of a U, is formed with the rectilinear central or base portion 4 which has a -cross section corresponding in shape to that of the groove 2 in the Wearing edge I.
  • the end or nail portions 5' of this fastening piece project upwardly at a right angle, as the corresponding nail portions of the form of fastening piece previously described, but these nail portions 5 of the embodiment illustrated in Fig. 4 are smooth instead of having the barbs of the embodiment shown in Figs. 1 to 3.
  • a U-shaped fastening piece for attaching a wearing edge to a ski comprising a straight elongated base portion with a dovetail-shaped cross-section, adapted to be slid into a dove tail groove of a wearing edge, said U-shaped fastening piece being formed at the terminal ends of .said base portion with integral upright nails, said upright nails projecting from both ends of said base portion substantially at right angles thereto, said nails being adapted to be hammered into a ski.
  • a reinforcing equipment for a bottom edge of a ski comprising a wearing edge at on one side and dovetail-grooved longitudinally on the opposite side, a plurality of U-shaped fastening pieces, each comprising a straight elongated base portion with a doVetail-shaped cross-section, adapted to be slid into the dovetail groove of the wearing edge, and integral upright nails projecting from both ends of said base portion at the terminal portions thereof, said nails projecting substantially at right angles thereto and being adapted to be hammered into the ski.
  • each of said spaced fastening pieces being tted into a longitudinally-extending groove which is dove-tail in cross-section formed in the portion of said wearing edge which abuts against said lower edge portion of said ski, each of said spaced fastening pieces being of substantially U-shape form and comprising a base portion which is substantially dove-tail in cross-section and of a size such as to permit of said base portion being slid into said longitudinally-extending groove in said Wearing edge, and terminal upwardly-extending nail portions protruding into said ski, one nail portion extending lat each terminal end of said base portion and protruding substantially at right angles to said base portion and said wearing edge.
