Definitions

  • Fig.v 1 shows: an: elevation of a form of embodiment. of; axski according to theinvention. For the: sake of. clarity, the ski has been drawn abnormallyrhigh; Fig. 2-. shows. a cross. section to: a. larger. scaleon; line: IIII in Fig. 1.
  • Fig. 3 isan elevationof another embodiment, and Fig. 4'showsaa .third:embodiment of the object according to the invention.
  • Fig. 5 shows a further embodiment, and Fig. 6 represents a blank for themanuf'acture oft" skisaccording to the invention.
  • I designates. a ski. blank consisting of wood orsimilar material, saicl'ski blank having longitudinally extendingrecesses 2 milled into the same from the upper side of the blank.
  • longitudinally extending slits? are out into the ski blank I..
  • Annpper front slit 3 and a lower rear slit '4' extendfrom the one to the other lateral face of the ski while passing each otherat-the middle portion of the skiblank.
  • the slits' are filledwithinsetsfi', B- of wood or the like of a-suitable thickness, and the ski blank is glued together on a form block to ensure the bend of the ski.
  • the ski blank with its insets is pointed obliquely downwardly toward the ends, and glued to the upper side of the blank is a thin plywood layer 1 extending all over the length and width of the ski and forming, together with the front end of the ski blank I and, perhaps, an intermediate wooden wedge 8, the brim of the ski.
  • the front slit 3 is arranged underneath the rear slit I, and the inserts are made wedge-shaped with th thinnest portion of the wedge directed inwardly to the center of the ski.
  • the insets (only one of which is shown) are made wedge-shaped with the thickest portions thereof directed inwardly toward the center of the ski.
  • an ordinary ski blank which may consist of one or more vertical and/or horizontal layers, is slitted from both ends, so that the slits will overlap one another at the central 2- portionof. theski.
  • the slits are filledwith insets fromwood: or the-like of. asuitable thickness. and the ski. blank. with its. insets. is glued. together on aform' block toprovide for the. bend of the ski.
  • one or more recessesor grooves are milled out from theupper; side of. the ski blank, said recesses or grooves-extending in the longitudinaldirection and having for their object to reduce the weight of the ski.
  • A. thin plywoodv layerv is glued onto theupper side. of the ski, said plywood'layer ex tending; all over; thelength and width of the ski, and at the same-timethe brim is bent, while a wedge-shaped inset: might be glued into the point of, the ski,.so thatthe-brim.
  • the extended portions.- I 2; I 3 may be glued at oblique joiningfacesIB and I6,,r.espectively.
  • wedge-shaped'wooden pieces I! and I8' are glued into the slits I0 and II on a form block, while the desired bend is at the same time imparted to the ski blank.
  • the wedgeshaped wooden pieces I! and I8 are made so long that their lower abutting faces extend as far as to the front and rear end, respectively, of
  • the ski while the upper abutting faces terminate at a distance in front of the brim-and the rear end, respectively, of the ski. Then the ski blank is moulded to the desired shape. If desired, the ski may also be provided with a wooden layer covering the whole of the upper side or the whole of the lower side thereof.
  • a ski having tapering end portions and at least one slit extending substantially longitudinally of the ski throughout the whole width thereof, said slit commencing on the upper side of one of said end portions at a distance from the end of the ski and extending toward the center portion of the ski, the faces of said slit being glued together.
  • a ski having tapering end portions and two slits extending substantially longitudinally of the ski throughout the whole width thereof, one of 3 said slits commencing on the upper side of one of said end portions, and the other slit commencing on the upper side of the other one of said end portions, said slits extending from points at some distance from the respective ski ends toward the center portion of the ski.
  • a ski having tapering end portions and twoslits extending substantially longitudinally of the I I ing on the upper side of the other one of said end portions, said slits extending from points at some distance from the respective ski ends toward the center portion of the ski, and a layer glued fast to the upper side of the ski to cover said upper side and the openings of said slits therein.
  • a ski comprising tapering end portions, two slits extending substantially longitudinally of the ski throughout the whole width thereof, one of said slits commencing on the upper side of one of said end portions, and the other slit commencing on the upper side of the other one of said end portions, said slits extending from points at some distance from the respective ski ends toward the center portion of the ski, and insets inserted into said slits and glued fast therein.
  • a ski comprising tapering end portions, two slits extending substantially longitudinally of the ski throughout the whole width thereof, one of said slits commencing on the upper side of one of said end portions, and the other slit commencing on the upper side of the other one of said end portions, said slits extending from points at some distance from the respective ski ends toward the center portion of the ski, and wedge-shaped insets inserted into said slits and glued fast therein.
  • said slits commencing on the upper side of one of said end portions, and the other slit commencing on the upper side of the other one of said end portions, said slits extending from points at some distance from the respective ski ends toward the center portion of the ski, and wedge-shaped insets inserted into said slits and glued fast therein, the thinnest portions of said insets being directed inwardly toward the center portion of the ski.
  • a ski comprising tapering end portions, two slits extending substantially longitudinally of the 'ski throughout the whole width thereof, one of said slits commencing on the upper side of one of said end portions, and the other slit commencing on theupper side of the other one of said end portions, said 'slits extending from points at some distance from the respective ski ends toward the center portion of the ski, and Wedge-shaped insets inserted into said slits and glued fast therein, said insets projecting from said slits toward the respective ski ends tapering toward said ends and glued to the upper sidethereof.
  • a ski comprising a middle portion and tapering end portions, two slits extending substantially longitudinally of the ski throughout the whole width thereof, one of said slits commencing on the upper side of one of said end portions and the other slit commencing on the upper side of the other one of said end portions, said slits extending from points at some distance from the respective'ski ends past one another at the middle portion of the ski, and insets inserted into said slits and glued fast thereon.
