Definitions

  • a disk for a ski pole is formed from four generally cloverleaf- [52] [1.8. CI ..280/ll.37 Z shaped vanes mounted on a ring which is limitedly swivelable [51] Int. Cl ..A63c 11/24 on the stem of the pole near its pointed lower end, the vanes [58] Field of Search ..280/11.37 being individually pivoted. to that ring for swinging downwardly under a load of snow into a limiting position in [56] References Cited which they may form a generally frustopyramidal structure. The vanes, when unloaded, may be retracted by a spring into a UNITED STATES PATENTS coplanar position perpendicular to the ring axis.
  • Conventional ski poles are provided with a stem having a pointed lower end and a disk near that point surrounding the stem to form a large-area supporting surface when the skier thrusts the pole into the snow. Since the pole may be held at differentangles when so used, the disk should be at least limitedly swivelable in every axial plane so as to orient itself parallel to the snow or ice surface for maximum support. On the other hand, the disk should be so designed that a load of snow resting on it, upon upward withdrawal of the pole, can readily slide off so as to reduce the effective weight of the disk.
  • the general object of my present invention is to provide a ski pole of simple construction satisfying the aforestated desiderata.
  • This object is realized, pursuant to my present invention, by the provision of a multiplicity (at least three and preferably four) of generally radially extending vanes surrounding the lower end of the stem with freedom of independent swingingv between a substantially coplanar position, generally transverse to the stem, and a downwardly deflected position which the vanes can assume under load so as to discharge any snow or ice entrained by the disk which these vanes define.
  • the vanes are pivotally secured to a mounting which advantageously takes the form of an annular holder limitedly swivelable about a median position perpendicular to the stem, this swivelability being attained by supporting the holder on a spherically curved boss forming therewith a universal joint or, more simply, by providing the stem with two axially spaced collars bracketing the holder with small clearance.
  • FIG. 1 is a face view of a four-vane disk for a ski pole according to the invention, showing the vanes extended;
  • FIG. 2 is a'fragmentary cross-sectional view taken on the line II'--II of FIG. 1, showing part of one vane in "its. deflected position;
  • FIG. 3 is a view similar to FIG. 2, illustrating a modification
  • FIG. 4 is-an enlarged face view of a universal joint supporting the vanes of FIGS. 1 and 2;
  • FIG. 5 is a side view, partly in section, of one of the vanes of FIG. 1;
  • FIG. 6 is a perspective end view of part of the vane-of FIG. 5;
  • FIG. 7 is-a view similar to FIG. 1, showing an alternate'embodiment
  • FIG. 8 is a cross-sectional view taken on the line VIIIVIII of FIG. 7;
  • FIG. 9 is a view similar to FIG.- 8, illustrating a further modification
  • the ring -2 serves as a holder for four radially extending vanes 6 of Cloverleaf shape, spaced 90 apart and terminating at their inner ends in pairs of transversely spaced loops 8 (see also FIG. 5) which straddle respective lugs 3 integral with ring 2.
  • the lugs 3 (see also FIG. 4) project radially outwardly from flat faces 4 of the ring 2 and are received in clearances 7 between the paired loops 8 which, as seen in FIG. 5, are open at 9 to facilitate the insertion of respective studs 5 projecting laterally from the lugs 3.
  • the studs 5 may be molded in one piece with the lugs 3 of ring 2 or, as shown, may consist of pins traversing these lugs.
  • each vane 6 is provided with a flat face 12 perpendicular to its top surface 11 and adjoining the corresponding facet 4 of ring 2, these faces 12 merging into an arcuately curved lower surface centered on the axis of studs 5.
  • face 12 comes to rest against the flat 4 of holding ring 2 so as to prevent any further upward swing of the vane.
  • a tongue 17 bridging the two loops 8 of the vane and depending therefrom in the normal position (FIG. 5)
  • the vanes 6 are also made of somewhat resilient resinous material so that the studs 5 may readily snap into the loops 8 to form the hinged connection with ring 2.
  • the entire assembly 2, 6 is limitedly swivelable on boss 15, the maximum angle of tilt being determined by a collar 32 on stem 14 (FIG. 2) forming an abutment for the undersurface of ring
  • FIG. 3 shows amodified joint with a generally toroidal boss 15', symmetrical with reference to a transverse plane 20, which is integralwitha tilt-limiting collar 32'.
  • the bore of ring 2 conforms to the spherically curved outer peripheral surface 16 of boss 15'.
  • FIGS. 7 and 8 I have shown a modified disk consisting of four vanes 6 which are removably secured by fasteners 27, here shown as screws, to respective supporting arms 21 hinged via pins 24 to lugs .23 of a spherically curved rubber boss 25.
  • the innerend of each arm 21 has an arcuate curvature similar to thatof lugs 8, FIG. 5, and terminates in a flat face bearing upon the boss 25 in the illustrated extended position of these arms to prevent a furtheroutward swing of the vanes 6'.
  • a mounting ring 25' is bracketed with small axial clearance by the aforedescribed collar 32 and a second, similar collar 33 overlying the ring.
  • the hooks 26' are formed integral with the vanes6' themselves, rather than with overlying strips 22 as in FIGS. 7 and 8.
  • These hooks and their encircling band-28 are encased. in a protective cap 30 of resilient material suspended froma collar 31 onstem 1'4.
  • a protective cap 30 of resilient material suspended froma collar 31 onstem 1'4.
  • the hooks 26 could also be made in one piece with the vanes as shown in FIG. 9.
  • a ski pole comprising a stem with a point at its lower end; an annular holder traversed by said lower end; and a multiplicity of generally radially extending vanes surrounding said lower'end near said point, said vanes having hinged inner extremities pivotally secured to said holder for.independent swinging about substantially horizontal axes between a substantially coplanar position generally transverse to said stern and a downwardly deflected position, said holder and said vanes being provided with cooperating formations for preventing an upward swing of said vanes beyond said substantially coplanar position and a downward swing thereof beyond said deflected position, said holder being limitedly swivelable on said stem about a median position perpendicular to the stem.
  • a ski pole as defined in claim '1 further comprising a pair of axially spaced collars on said stem bracketing said holder with small clearance.
  • a ski pole comprising a stem with a point at its lower end; an annular holder traversed by said lower end; and a multiplicity of generally radially extending vanes surrounding said lower end near said point, said vanes having hinged inner extremities pivotally secured to said holder for independent swinging about substantially horizontal axes between a substantially coplanar position generally transverse to said stem and a downwardly deflected position, said holder and said vanes being provided with cooperating formations for preventing an upward swing of said vanes beyond said substantially coplanar position and a downward swing thereof beyond said deflected position, said vanes being of generally trapezoidal configuration with outwardly diverging sides closely juxtaposed in said deflected position to form a substantially frustopyramidal structure, said vanes being substantially flat with upturned outer edges.
  • a ski pole comprising a stem with a point at its lower end; an annular holder traversed by said lower end; and a multiplicity of generally radially extending vanes surrounding said lower end near said point, said vanes having hinged inner extremities pivotally secured to said holder for independent swinging about substantially horizontal axes between a substantially coplanar position generally transverse to said stem and a downwardly deflected position, said holder and said vanes being provided with cooperating formations for preventing an upward swing of said vanes beyond said substantially coplanar position and a downward swing thereof beyond said deflected position, said holder having a substantially circular outer periphery with angularly equispaced flats constituting part of said cooperating formations and with lugs projecting radially from said flats in pivotal engagement with respective vanes.
  • a ski pole comprising a stem with a point at its lower end; an annular holder traversed by said lower end; and a multiplicity of generally radially extending vanes surrounding said lower end near said point, said vanes having hinged inner extremities pivotally secured to said holder for independent swinging about substantially horizontal axes between a substantially coplanar position generally transverse to said stem and a downwardly deflected position, said holder and said vanes being provided with cooperating formations for preventing an upward swing of said vanes beyond said sub-- stantially coplanar position and a downward swing thereof beyond said deflected position, said vanes terminatin in hooks proximal to said stem; and a resilient band encirc mg said stem and inter-linking all said hooks for biasing said vanes into said substantially coplanar position.
