Definitions

  • This invention relates generally to ski equip- ment, and more particularly to a ski or ski pole construction capable of being quickly broken into sections for ease of transport, the sections being readily reassembled for use.
  • the present invention provides a ski comprising a) at least two ski sections interconnectable end-to-end, b) one ski section having a recess sunk in an end portion thereof and the other ski section having a tongue projecting from an end portion thereof, the recess and tongue being shaped to closely interfit when the ski sections are assembled, end-to-end, and c) means to positively and releasably interconnect said end portions in assembled condition.
  • the tongue and recess may have wedge interfit, as for example in directions endwise, lateral to, or perpendicular to the ski top surface length dimension; and inter­engageable stop shoulders may be provided on the sections to strengthen the assembled ski sections as against bending during use.
  • the inter­connection means may typically comprise a fastener, or fasteners, that extend between the sections near the tongue and recess (and typically intersect same), the fasteners being characterised as easibly removable and re-insertable.
  • a ski binding plate may overlap the joint between the sections to assist in positive fastening.
  • the present invention additionally provides a ski pole comprising at least two sections intercon­nectible via tongue and groove parts, as will be seen; and the provision of an easily transported carrier for disconnected ski and ski pole sections of the present invention.
  • a ski 10 includes two sections 10 a and 10 b , the joint therebetween indicated generally at 11. That joint is typically located at about the mid position, endwise, of the ski, so that each of the sections is about 1/2 the ski overall length. This greatly facilitates carriage or transport of the two sections in side-by-side relation, for example.
  • One ski section has a recess sunk in an end portion of same, and the other ski section has a tongue projecting from an end portion thereof.
  • the recess and tongue are shaped to closely interfit when the sections are assembled, end-to-end, to provide the full length ski of bending strength substantially equivalent to the bending strength of the same ski with unbroken construction.
  • the recess and tongue are indicated at 12 and 13 as respectively associated with ski end portions 14 and 15, in Figs. 4 and 5.
  • the illustrated recess has upper and lower interior walls 12 a and 12 b which taper in the interfit direction indicated by arrow 16; and the tongue has upper and lower exterior walls 13 a and 13 b which taper in direction 16 to engage with 12 a and 12 b on make-up.
  • the recess has opposite side walls 12 c and 12 d which taper in direction 16, and the tongue likewise has opposite side walls 13 c and 13 d which taper in direction 16 to engage recess walls 12 c and 12 d upon make-up.
  • Interengageable stop shoulders to limit make-up are indicated at 17 a and 17 b , 18 a and 18 b , 19 a and 19 b , 20 a and 20 b , and 21 a and 21 b , in Figs. 4 to 6.
  • Shoulders 18 a to 21 a are on ski-section 10 b , and surround the tongue at its base. Also, shoulders 18 a to 21 a define the junction line 11, seen in Figs. 1 to 3.
  • Interengaged shoulders 20 a and 20 b and 21 a and 21 b aid in resisting relative up and down bending of the ski sections, at joint 11, the inter-engaged tongue and recess walls also resisting such relative bending.
  • fasteners 22 and 23 have tapered heads 22 a and 23 a received against tapered seats 22 b and 23 b in the portion of ski section 10 a ; also the fastener shanks 22 c and 23 c pass down­wardly through openings 22 d and 23 d in the tongue, and then have threaded interfit with the lower portion of the ski section 10 a , at loci 22 e and 23 e , all of which is seen in Fig. 2.
  • Fastener 24 extends obliquely downwardly and endwise (relative to the ski sections), and has a head 24 a on an internal shoulder in the section 10 a , and a threaded shank 24 b , into a threaded bore 24 c in the end of tongue 14.
  • a ski binding plate 25 is shown as overlapping the two sections 10 a and 10 b , i.e. across joint 11, and as removably connected thereto, as via fasteners 26 and 27.
  • the latter have heads that seat in tapered openings in the plate, and shanks that pass downwardly into threaded openings in the ski sections, endwise beyond the tongue and groove loci.
  • ridges 28 On the top of plate 25 are ridges 28 that interengage similar ridges on a skier's boot.
  • Fig. 7 shows a greater length of ski 10, and in all-metal form.
  • the ski sections 10 a and 10 b are constructed of metal portions 10 a ' and 10 b ', and molded glass-fiber portions 10 a " and 10 b ".
  • Portions 10 a ' and 10 a " are integrally interconnected at endwise V-tapered joint 29, as shown; and portions 10 b ' and 10 b "are likewise integrally interconnected at endwise V-tapered joint 30.
  • the ski sections 100 a and 100 b correspond in general to sections 10 a and 10 b above.
  • Tongue 113 integral with end portion 114 of section 100 b wedgably interfits recess 112 formed in the end portion 115 of section 100 a .
  • the interfit is lateral of the ski lengthwise dimension, i.e. direction indicated by arrow 116.
  • Tapers 112 a and 113 a interengage on make-up, as do tapers 112 b and 113 b .
  • Interconnection fasteners 124 and 125 extend laterally, as shown, to releasably interconnect the sections at the tongue and recess locus.
  • Fig. 11 the construction is like that in Figs. 9 and 10, except that stop shoulders 217 and 218 (corresponding to 117 and 118 in Fig. 9) and stop shoulders 219 and 220 (corresponding to 119 and 220) are angled or bevelled, as shown. Also, a smaller tongue 230 on section 214 interfits a recess 231 on section 215, adjacent shoulders 217 and 218; and, a smaller tongue 232 on section 215 interfits a recess 233 on section 214, adjacent shoulders 219 and 220.
  • Fig. 12 the construction is again similar to that of Figs. 9 and 10, except that the tongue 330 on section 315 extends in direction 350 into the recess 331 in section 314 with wedging interfit.
  • Direction 350 is at an angle ⁇ relative to the ski lengthwise direction. Angle ⁇ is less than 90° and is between about 25° and 65°.
  • Fasteners 324 and 325 extend from recesses in section 314 into threaded openings 324 a and 325 a in the tongue. Stop shoulders 315' and 316' on the sections define a plane which extends at an angle ⁇ relative to the ski lengthwise direction. Angle ⁇ is between 90° and 180° and is typically between about 135° and 160°.
  • Figs. 13 and 14 the two tongues 430 on section 414 extend in direction 450 into recesses 431 in section 415, with wedging interfit.
  • Direction 450 indicated by the arrow is perpendicular to the flat plane of the ski top surface.
  • Ski portions 416 and 417 have overlapping-underlapping relationship as shown, and define an interengagement plane 418.
  • Fasteners 420 and 421 have heads received in portion 416 and shanks threadably received in portion 417 to positively interconnect the sections. Stop shoulders appear at the ends of portions 416 and 417, at locations 423 and 424.
  • Fig. 15 the construction is again like that in Figs. 13 and 14, except that the ski portions 516 and 517 that have overlapping-underlapping relation­ship define an interengagement plane 518 that is tilted relative to the plane of the ski top surface 519.
  • the endwise tapered tongue 360 integral with end portion 361 of ski section 362 wedgably interfits endwise tapered recess 363 formed in the end portion 364 of ski section 365.
  • the tapers 360 a and 363 a interengage on make-up, as do abutting stop shoulders 366 and 367.
  • stop shoulders 368 and 369 on the surrounding glass fiber ski sections interengage on make-up, and align with shoulders 366 and 367 to form a single joint.
  • Portions 361 and 364 are metallic inserts in the surrounding glass fiber body material.
  • Fig. 17 is a view like Fig. 4, and bears the same reference numerals except for end shoulders 21 a ' and 21 b ' (corresponding to shoulders 21 a and 21 b in Fig. 4).
  • Shoulders 21 a ' and 21 b ' diverge in directions away from the tongue 13, to provide relief, permitting greater joint bending flexibility, vertically.
  • the angle of divergence may be less than about 5° to permit ultimate inter­engagement of the shoulders 21 a ', 21 b ' to limit more flexible bending.
  • Fig. 18 is again like Fig. 4, and also Fig. 17, except that a bending flange 380 integral with ski end portion 15 resiliently resists upward deflection of end portion 14.
  • a horizontal projection 381 on section 14 engages vertical flange 380, as shown, above its juncture 382 with section 15, to forcibly urge it to the left, as section 14 flexes upwardly.
  • a ski pole 450 includes sections 451 and 452.
  • Sections 451 includes rod 451 a and end portion 451 b ; and section 452 includes rod 452 a and end portion 452 b .
  • End portion 451 b and 452 b have opposed terminals 451 c and 452 c which are typically engaged when the end portions are assembled together. They define a plane 453 which extends non­perpendicularly, i.e. at angle ⁇ , with respect to the axis 454 defined by the section. That angle is typically between 30° and 60°.
  • End portion 451 b defines a tongue 455 projecting into and interfitting a recess 456 defined by end portion 452 b .
  • the tongue and recess have interfitting tapers, as for example are represented at locations 457 and 458, as in the case of the ski section described above.
  • a removable fastener means such as threaded fastener 459, projects as shown through the tongue and groove, and between end portions 452 b and 451 b , to hold the latter together.
  • fastener 459 is removed, as by inserting a screw driver tip 460 into the side recess 461 in end portion 452 b , and into the groove 462 in the fastener head, to rotatably back the fastener out of retaining position.
  • Fig. 20 shows the tongue and recess 456 as typically having generally rectangular cross sections.
  • a ski equipment carrier in the form of a case 470 has side, bottom and top walls 471 to 474, and a handle 475 for transport. Interior wall 476 is spaced inwardly to form a recess 477 in the case adapted to receive ski equipment. Pockets 480 and 481 on wall 476 have open upper ends to receive disconnected ski sections 482 as referred to above. Pockets 483 receive disconnected pole upper section, and pockets 484 receive pole lower sections. A parts compartment is shown at 488.
  • the case may be closed, as by folding about axis 485, for transport or storage. Retainers 486 and 487 then interconnect to hold the case closed.
  • the modified carrier 490 forms a pack to be carried by the skier's body, as with front and back panels 490 a and 490 b .
  • a neck or head hole 491 passes over the head of the skier, so that pack shoulder portions 490 c are carried by the skier's shoulder.
  • the carrier has inverted U-shape. Pockets for ski sections, pole sections and shoes appear at 492 to 494, on each of the panels, for equally distributing weight.
  • a utility pocket appears at 495.
