Definitions

  • the present invention relates to extensible ski poles of the type that are -composed of 4two or more relatively displaceable andnlockable members. s
  • Such poles usually comp-rise two telescopic tubes, for instance, tubes of steel or aluminum, and the outer or upper tube forms the handle and surrounds the tube below.
  • Fig. 1 is a view, partly insection,vof a portion of an extensible ski pole illustrating the pole in its extreme collapsed condition;
  • Fig. 2 illustrates in a similar manner the ski pole when extended to about its maximum length
  • Fig. 3 shows on an enlarged scale, an axial section through the top part of the ski vpole shown in Fig. l;
  • Fig. 4 is a section on lines IV-IV of Fig. 3;
  • Fig. 5 is a section on lines V-V of Fig. 3;
  • Fig. 6 is a longitudinal section showing in separate relationship the collar provided at the top of the inner tube and after removal of the spindle emphasized in the device;
  • Fig. 7 is an end View of the collar; and I Fig. 8 illustrates, on a somewhat larger scale, a section through the top end of the inner tube and collar with the spindle extending from the collar.
  • the ski pole comprises a generally hexagonal tube I, thatkis movably tted over the tube 2. ⁇ vThe latter may extend to the bottom end of the ski pole or it may be secured to the end of a tube of still smaller diameter, which then may form the bottom part of the ski pole.
  • the lowermost portion I of .tube I is cylindrical and closely fits over tube 2'.
  • a hexagonal metallic plug 3 Secured in the top end of tube I by means of screws 4 is a hexagonal metallic plug 3 having an.
  • a spindle 'l is freely rotatable.
  • the top end of said spindle projects somewhat beyond tube I and plug 3 and is provided with a knurled circular or polygonal knob ⁇ 6, which serves as a finger piece for rotating the yspindle relatively to the outer tube.
  • the knob is at its underside provided with a recess forming bearing for a ange 3 of the plug 3.
  • the spindle 'I is provided with a stop abut- Norway December 28, 1944 ment for the inner end of the plug in order to prevent axialdisplacement of the spindle.
  • the abutment may consist of a nut 8 screwed onto the spindle and locked by means of a locking nut 9, or it may be connected to the spindle by welding or the like.
  • the spindle 'I is provided with screw threads or transverse serrations 23 which are entirely or in part cut away at two opposite sides of the spindle.
  • the spindle is attened slightly so that fiat portions 1 intervene between the threaded portions. ⁇ 'Ihe spindle thus attains across sectional shape as shown in Figure 8;
  • the rod 'I is adapted to be received in an axial opening of a collar or sleeve I0 secured in the top end of the inner tube 2.
  • the collar may be forcetted into the wall of tube 2, or may be secured thereto inra-ny other suitable manner.
  • a hexagonal portion Ill of the collar extends beyond the end of tube 2, and slidably fits into hexagonal tube I. Thus tubes Land 2 are locked against l relative rotation.
  • the axial bore. ofv the collar or sleeve I0 and ⁇ the portion, I 0 thereof areprovided with internal screw threads ⁇ ortransverse serrations I2 which l cooperate with the external threads or serrations .l is rotated 4to a position where the screw threads of the spindle engage thescrew threads of the collar ⁇ I0, I0', the outer tubewill be locked to the inner tube '2. If the ⁇ ski poleis to be extended or shortened, the knobk 6 'and thus also the spindle 1 is rotated about to .that angular position where the threads of the spindle are entirely out of engagement with the threads of the collar I0, I0. .f The screw threads.
  • spindle 1 and thus also outer tube I may be displaced longitudinallyluntil the ski pole attains the desired length, whereafter locking is effected byturning thelspindle l, by means of knob 6, by 90, into ⁇ a positionwhere the screw threads of spindle and, collar engage. l
  • the inner end portiony of the spindle.4 may have screw threads 3 about its entire periphery. On assembling the pole, such end portion must then be screwed entirely through the collar.
  • the inner end of the spindle i-s provided with a suitable stop abutment, for instance in the shape of nuts I3.
  • a ball or the like- I5 is provided in each of say, two opposite holes.
  • the balls are actuated by spring I4 and are adapted to rest alt ternatively in one or the other wall of recesses I6, disposed at positions displaced 909 relatively in each other on the underside-of. knob 6..
  • the holes are. ⁇ diam'etrically opposed andare spaced' axially by a' distance cor'- responding to one or several' thread pitches. Further, the holes have such angular'position's, that the balls .I8 are pressed against the threads' of spindle 1: when the latter. is in unlocked position.
