Definitions

  • This invention relates to skis and more particularly to a sectional ski.
  • Skis are normally rather lengthy and bulky objects and may be, for example, five to seven feet in length requiring that during the transportation of the skis in an automobile, if the automobile is of a compact variety or transporting a number of persons, a rack must be used on the exterior of the automobile for transporting the skis.
  • Skis have been developed in sections in an attempt to eliminate this key transportation problem.
  • Some sectional ski devices are shown and described in United States Patents No. 3,439,928; 3,797,838; 3,819,198; and 3,825,360.
  • Another attempt utilizing a folding ski approach is shown and described in United States Patent No. 2,450,538.
  • the coupling members In the sectional ski devices, the coupling members generally require machining in order to provide a very tight tolerance for fitting the parts together in order to give the ski stability in the longitudinal direction during use. Machining of mechanical parts increases the price due to the expense of the machining.
  • the ski coupling member includes an elaborate dovetail arrangement with a transverse slot for receiving an insert which provides additional support for the joint and prevents undesired transverse flexing of the members of the joint.
  • the particular configuration requires that the dovetails be machined with close tolerances, and furthermore due to the large number of dovetails, a corresponding increase in time is required.
  • the coupling arrangement requires that one of the coupling members have a cavity formed therein for communicating with the edge for receiving a matingly contoured T-shaped bar portion on the other coupling portion with a fastening member engaging the coupling members on an axis generally parallal to the surface of the skis.
  • the coupling arrangement likewise, requires cutting and machining to close tolerances.
  • the simplest coupling arrangement for a sectional ski shown in United States Patent No. 3,819,198 has the coupling members engaging on a diagonal plane relative to the surface of the ski with dowel pins located on one of the coupling members for engaging aligned apertures in the other with suitable screw means fastening the members together along a plane generally perpendicular to the diagonal.
  • a sectional ski having first and second ski sections with a first coupling member having a bar-shaped portion insertable within a slot generally parallel to the surface of the ski and an enlarged portion which forms a continuation of the contour of the ski.
  • a second coupling member of generally similar configuration is secured to the end of the other ski section with the enlarged portions of both coupling members having the end thereof configured to form tongue and groove means connectible by joining along a path of travel generally parallel to the plane of the surface of the ski.
  • the coupling members are of cast configuration with a taper forming a wedge in the direction of insertion for locking the members together to thereby joint the ski sections.
  • Suitable fastening means may be provided for engaging the so coupled members together along a line generally perpendicular to the plane of the surface of the skis.
  • FIG. 1 there is shown an assembled sectional ski generally designated 10 formed from a first section 12 interconnected to second section 14 by means of first and second coupling members generally designated 16 and 18.
  • the upper surface of the ski 10 has a central portion immediately above the coupling members 16 and 18 which is the boot supporting portion 20 wherein a boot is retained between a toe piece 22 (shown in dotted line) and a releasable ski binding means 24 (also shown in dotted lines).
  • the first coupling member 16 has an elongated generally bar-shaped portion 26 insertable within a slot 28 with the bar-shaped portion 26 being disposed in generally parallel relation to the upper and lower surfaces of ski section 12.
  • the bar-shaped portion 26 may be secured within slot 28 by any suitable means and the surface thereof may be suitably configured to assist in the securing.
  • the other end of coupling member 16 is an enlarged portion 30 having upper and lower surfaces generally parallel to each other and configured to form a continuation of the contour of the upper surface and lower surface of the ski section 12.
  • the other coupling member 18 is generally similarly configured with an elongated bar-shaped portion 32 secured within a slot 34 formed in the end of the second ski section 14, the coupling member 18 likewise having an enlarged portion 36 with the upper and lower surfaces thereof generally parallel to each other and generally co-extensive in contour with the upper and lower surfaces of second ski section 14 to form a continuation thereof.
  • the overall width of the coupling members 16 and 18 is substantially identical to the width of the ski sections 12 and 14 with the overall height of the enlarged portions 30 and 36 being generally identical to the thickness of the ski sections 12 and 14 respectively.
  • the coupling members 16 and 18 are configured for connecting together end to end in tight fitting relation to provide the assembled ski 10 shown in Fig. 1.
  • This interconnection is accomplished by means of a transversely extending tongue portion 38 formed in one end of the enlarged portion 36 of the coupling member 18 with the tongue 38 being configured for sliding engagement within a groove 40 formed in the end of the enlarged portion 30 of coupling member 16.
  • the tongue 38 extends in a direction generally parallel to the upper and lower surfaces of the enlarged portion 36 and is located generally centrally with respect to the edge thereof. In side elevation, the tongue 38 is beveled so that the outer edge 42 thereof is deeper or thicker than the edge adjacent the connection with the enlarged portion 36.
  • the groove 40 extends along a line generally parallel to the upper and lower surfaces of ski section 12 with the inner surface 44 thereof deeper than the dimension between adjacent surfaces adjacent the edge thereof.
  • the tongue 38 and groove 40 are tapered at approximately four to forty degrees to provide a wedge fitting when the tongue 38 is inserted within the groove 40 by sliding in a plane generally parallel to the plane of the surfaces of the ski with the leading enlarged end 42 of the tongue 38 in abutting engagement with the side 44 of the groove 40.
  • the tongue 38 is slightly shorter than the overall width of the enlarged portion 36 of the coupling member 18, and the end of the groove 40 in the direction of insertion is provided with stop edge 46 for abuttingly engaging the shortened end of the tongue 38.
  • an aperture 48 Centrally disposed within tongue 38 is an aperture 48 positioned for alignment after insertion with upper and lower apertures 50 and 52 respectively formed in the enlarged portion 30 of coupling member 16 in communication with the groove 40.
  • the upper aperture 50 is countersunk about the periphery thereof for receiving the head of a shoulder screw 54 which passes therethrough, thence through aperture-48 of tongue 38, into threading engagement with the aperture 52 which is threaded.
  • the threaded end of shoulder screw 54 is of slightly smaller diameter than the main body portion thereof.
  • the coupling members 16 and 18 are cast members with four to twenty degrees of taper of the mating co-acting tongue and groove members 38 and 40 respectively being within the tolerance of the mold during casting, thus providing coupling means integral with the coupling members 16 and 18 respectively with virtually no machining required which machining could tend to weaken the parts due to the application of heat and friction. Furthermore by utilizing this tolerance of the mold, the tongue 38 engages the groove 40 in sliding relation in a wedge-shaped manner until the shortened end of tongue 38 abuts against the stop egde 46.
  • the coupling members 16 and 18 are then joined by insertion of the shoulder screw 54 through aperture 50 through aperturu 48 for threading engagement with aperture 52, the apertures 48 and 50 being precisely drilled to the diameter of the main body portion of shoulder screw 54 to' provide a solid connection for joining together the ski sections 12 and 14 in endwise abutting relation to form the unitary ski assembly 10 shown in Fig. 1.
  • the captivity and adhesion of the ski sections 12 and 14 and coupling members 16 and 18 is enhanced by tapering their respectively opposing mating surfaces 80, 81 and 82, 83 in the range of 30 to 60 degrees as shown in Fig. 4.
  • said taper strengthens the bonded joints 80, 81 and 82, 83 by lengthening the adhering cross-sectional surface area whereat bonding occurs and structural soundness is critical to good sectional ski design criteria.
  • an additional feature has been added to facilitate assembly and disassembly of respectively opposing ski sections, said feature being a ring 58 which is attached to the head of screw 58 and which folds down and fits into the aperture 60.
  • the screw 58 is provided with an anti-rotation tang so as to lock screw 54 in its fully inserted position after the screw is fully screwed in place.
