Definitions

  • This invention relates to a ski sled which is capable of slalom movements over the snow or other skiing surfaces Ibut which is manageable simply by inclination of the rests supported by the skis in which one or more persons can sit, lie or otherwise be positioned.
  • each of the skis are connected to the bottom side of the platform by a pair of laterally spaced-apart rods pivoted at their lower ends to laterally spaced-apart portions on the top surface of t-he skis and their upper ends to laterally spaced-apart portions on the bottom side of the platform with the pivot for the inner rods ⁇ being preferably located along the center line of the platform. Best results are secured when the pivot points form a parallelogram so that the pivot of the platform will effect concurrent tilting movement of the skis by about a corresponding amount.
  • skis it is desirable, from the standpoint of maneuverability and safety, as well as ease of operation that the skis remain in contact, substantially throughout their lengths, with the skiing surface. This is diicult to achieve when the surface has variations in contours such as occur on water or rough terrain. To maintain maximum contact between the skis and the underlying surface, it is important for the skis to be free to flex and thereby permit the skis approximately to follow the surface contours.

  • FIGURE ll is a plan view of the 'base plate forming a part of the bracket shown in FIGURE l0;
  • FIGURE 12 is a fragmentary elevational view illustrating the ilexibility in the ski mounting bracket.
  • the ski sled of this invention is formed with a seat 11 inthe form of a substantially at platform and a pair of laterally spacedapart skis 12.
  • the platform is supported in vertically spaced-apart relation above the pair of skis by a rod system which is effective to cause the skis to incline sidewise in one direction or the other about their longitudinal axes responsive and concurrently with corresponding tilting movement of the platform.
  • the latter may -be effected by shifting of weight or force bythe operator at rest on the platform or seat 11.
  • a group 13 of rods at the forward end portion of the platform and a similar group 13' of rods at the rearward end portion of the platform. Since the two groups of rod systems are substantially the same, the description of one group 13 will suflice to describe the other group 13.
  • the rods in each group are substantially crosswise aligned and include -a hooped rod 14 having archedcentral portion 32 and substantially straight end portions 31 which extend angularly downwardly and outwardly from the central portion 32.
  • Rod 14A is pivoted at its lower end to the top surface of one ski while rod 14B is pivoted at its lower end to the top surface of the other ski, and rod 14 is pivoted at its center 32 at Aa point substantially aligned with the center line of the platform, and it thus defines the pivotal axis of the platform.
  • the other two rods 17 are spaced outwardly of the straight portions of the inner rods 14A and 14B with the v rod 17A pivoted at its lower end to the ski and at its upper end to the platform but with the pivots also spaced outwardly from the pivots for rod 14A and preferably spaced outwardly Iby an equal amount.
  • the other rod 17B is ⁇ similarly pivoted at its lower end to the other ski and at its upper end to the platform.
  • the rods 17A and 17B will move relative to the substantially straight portions of the inner rods 14A and 14B to effect a substantially equal corresponding tilting movement of the skis in the same direction.
  • the straight portions of the rods 14 and 17 need not be parallel if it is desired to actuate the movement of the skis by comparison with the movement of the platform.
  • the inner rod can be formed of a pair of rods pivoted at their upper ends along the central lline of the platform and with their lower ends pivoted to the respective skis as previously described.
  • a corresponding arrangement is effected between the rearward group of rods 13', between the skis and platform. Since it is desirable to provide a downward tilt to the platform 11, the rearward group of rods are preferably formed to shorter lengths than the forward group, as illustrated in FIGURES 2 and 4. It will be understood that the same results may be accomplished by the use of rods of equal lengths in both groups 'but by making use of a spacer member on the bottom side of the platform at the forward end thereof and from which the forward group of rods 13 are pivoted.
  • Tilting the platform to effect corresponding tilt of the skis will effect the desired steering or slalom movements of the sled somewhat in the same manner as employed in conventional skiing.
  • the ski sled can be made to weave its way down a slope.
  • the relative movements resulting from the tilt of theV platform in one direction will operate to bring the adjacent pairs of inner and outer rods 14A and 17A or 14B and 17B into closer side-by-side relationship to the end that the amount of tilting movement capable of being effected will be limited by engagement between the rods. Since the degree of maneuverability depends on the maximum angle of tilt which can be effected, it is desirable that Ithe relative lateral displacements between the pairs of rods be maximized.
  • the surface of one rod adjacent the other rod is formed with an indented or concave portion 14C which is adapted to receive the adjacent rounded surface 17C of the other rod, as shown in FIGURE 7.
  • the rods are adapted to intert thereby correspondingly to increase the amount of lateral displacement with corresponding increase in the angularity or 4tilt possible to be achieved.
  • An important feature of this invention resides in the flexibility in the pivotal connection between the lower ends of the rods and the ski members whereby a knee action is made available for greater maneuverability of the skis substantially independently one from the other and relative to the platform whereby the skis are capable of auto# matic self-adjustment for accommodating differences in surface formations, surface levels and the like for a smoother and safer ride, without interfering with the tilt of the skis responsive to tilting movement of the platform, as previously described.

  • the base portion 22 is xed to the top surface of the skis while the lower ends of the rods 14 and 17 are pivotally connected in the desired laterally spaced-apart relation to the bearing member 23, as illustrated in FIGURES and 6.
  • the bracket 20 consists of a ilat base portion 22 adapted securely to be fastened to the top surface of a ski,
  • the base portion 22 is secured to the ski by fasteners 19 inthe form of nut and bolt members.
  • the bearing surface 40 extends upwardly curvilinearly ⁇ from the base portion 22 and is provided with a central opening 29 extending therethrough at the apex or axial portion.
  • the bearing member 23 comprises a rigid plate which may be lformed of sheet metal having a plate, horizontally disposed flange members 33A extending outwardly from the opposite edges of a central spherical section 24 which is formed to concave curvature corresponding to the bearing surface 40 and which is also provided with an opening 28 at its apex for axial alignment with the opening 29 in the bearing surface but in which ythe opening 28 is of smaller diameter than the opening 29 and dimensioned to enable the shank 27 of a fastening bolt or rivet 27A to extend therethrough in fitting relationship.
  • the ange portions 33A are each provided with upstanding bracket members such as a pair of longitudinally spaced ears 25 having lengthwise aligned openings 25A for receiving a pivot pin 25B therebetween on which the lower ends of the rods 14 and 17 are mounted in laterally spacedapart relation for rocking movement about the pin as a pivot in the crosswise direction about a longitudinal axis.
  • the bearing member 23 is mounted on the bearing surface with the flanges 33A extending crosswise of the skis and with the pins 25B on the ears 25 spaced laterally by an amount corresponding to the desired space relationship between the pivoted lower ends of the rods 14 and 17.
  • the concave spherical section forming the bearing surface 24 of the bearing member 23 has substantially the same curvature as the spherical section of the bearing surface 40 on the base member 20 but preferably is of a depth slightly less than that of Ithe base member so as to permit the bearing member 23 to be received in mating relationship on the bearing surface 40.
  • the mating surfaces of the bearing members are held together, as by a fastening means comprising the rivet 27A having a shank which extends through the opening 28 in the bearing member into the aligned opening 29, in the bearing surface to a bearing washer 26 Aseated firmly against the underside or concave surface 40.
