Definitions

  • My present invention relates to a slidecraft or ski coaster comprising a frame to which a rear ski is hinged, a forward ski being hinged to the lower end of a control column or steering post which is removably and rotatably journaled in a depending forward leg of the frame and carries a handlebar.
  • the handlebar is mounted on a tubular extension of the control column telescopically connected therewith by releasable fastening means.
  • the detached control column and the forward ski connected to it can be swung through 180 about an axis perpendicular to its longitudinal axis whereupon the control column can be reinserted into the forward leg of the frame in this reversed position.
  • the tubular steering-post extension carries a lateral, short nipple having a screwthreaded bore, an insert of the steering post being formed with a transverse bore aligned with the tapped bore of the nipple.
  • a bolt is screwed into the tapped bore and has an inner end portion received in the transverse bore of the insert to connect the extension tube to the steering column.
  • the bolt has a conically tapered shank terminating in a cylindrical tip, the bore of the insert being correspondingly shaped.
  • FIG. 1 is a general view showing the slidecraft in position for use
  • FIG. 2 shows the knocked-down slidecraft with the handlebar removed
  • FIG. 3 is a fragmentary sectional view of the front end of the craft on an enlarged scale.
  • a handlebar 1 above the level of a seat 16 is rigidly secured to a tube 2 telescopically receiving an upwardly projecting extremity of an inner tube 3.
  • a short tubular boss or nipple 4 is welded to the rear side of the tube 2 and provided with 3,436,091 Patented Apr. 1, 1969 a tapped bore 5 which extends also through the wall of the tube 2.
  • An insert 6 of plastic material is snugly fitted in the inner tube 3.
  • a connecting bolt 8 is provided at its outer end with a handwheel 7 and adapted to be screwed into the nipple 4.
  • the inner end portion of the bolt 8 is conical at 9 and terminates in a cylindrical tip 10.
  • the insert 6 is provided with a tapered bore 11 ending in a cylindrical recess 12.
  • the inner tube 3 constitutes a steering column and is rotatably mounted in a front leg 13 of an upwardly curved frame 14 supporting a seat.
  • a forward ski 15 is hinged to the lower end of the inner tube 3.
  • the special slope of the shank 9 and of the tip 10 of the connecting bolt 8 coacting with the corresponding bore sections of the insert 6 ensures a firm connection between the tubes 2 and 3.
  • This connection will withstand all stresses and can easily be released when desired.
  • the handlebar 1 and the tube 2 connected to it can be removed whereupon the inner tube 3, which constitutes the steering column, and the forward ski 15, which is hinged to the inner tube 3, can be pulled downwardly out of the front leg 13 of the frame 14.
  • the tube 3 can then be swung through about an axis which is perpendicular to the longitudinal axis of the tube 3 and can be inserted from above into the leg 13.
  • the slidecraft can be transported Lll'lllCh more easily in this collapsed condition shown in FIG. 2, in which the front ski 15 overlies the drivers seat 16 above frame 14.
  • a radial flange 2' at the lower end of tube 2 engages a coextensive flange 13' at the upper end of frame portion 13 to help define the axial position of the steering post relative to the vehicle frame.
  • rear ski 17 is shown connected at 17' to the frame leg 13, as disclosed and claimed in my copending application Ser. No. 615,244 of even date.
  • a ski coaster comprising a frame with a rear portion and a tubular front leg, a seat supported on said rear portion, a rear ski secured to said rear portion, a steering post journaled in said front leg, a front ski joined to the bottom of said steering post, the latter being provided with an upwardly projecting extremity and a tubular extension telescopically receiving said extremity, a handlebar rigid with said extension, and fastening means detachably connecting said extension with said extremity, said extension having a lower end resting on an upper end of said tubular front leg.
  • a ski coaster as defined in claim 4 wherein said bore terminates in a cylindrical recess, said bolt having a cylindrical tip engaging in said recess.
