Definitions

• a device for changing between two different tips on a pole is a device for changing between two different tips on a pole.
• the present invention relates to a device for changing between two different tips on a pole.
• a disadvantage is that the users may forget to bring along the caps, and that the caps when removed may be dirty due to soil and similar and thus are not suited for being contained in pockets, bags or similar without being put into a separate bag. There also is the danger that the caps may loosen during use.
• A.C.C. AB where a rubber sleeve is screwed onto the end of the pole.
• the rubber sleeve has a throughgoing, threaded passage parallel to the pole.
• the sleeve may be in a position where it has been screwed as long up on the pole that a spike on the end of the pole protrudes out of the passage.
• the sleeve may be screwed down around the spike, whereby the lower end of the sleeve comes in contact with the substratum, and whereby the spike lies concealed inside the sleeve.
• US 3637229 shows a similar solution, where a pole-shaped spike is provided inside of the tip on a pole, whereby the tip has a longitudinal hole in which the spike is guided and may be shifted.
• the spike may be moved as long upwardly in the pole that it does not protrude outside of the tip.
• the spike may be moved out from the tip.
• a spike For crutches is known to mount a spike on a lever hinged to the crutch pole, whereby the spike may be pivoted upwardly when not in use and pivoted down to below the rubber foot of the crutch when it is to be used.
• the present invention may also be used on crutches and, moreover, on walking sticks, but it is primarily adapted for use on poles used for Nordic Walking.
• the present invention relates to a device for permitting changing between two tips on a pole, and is characterized in that it comprises a member having two end pieces in the form of a pointed tip for use on soft substratum and ice and a tip having a soft pad for use on hard substratum, respectively, said member being fastened to an inclined plane on the end of a pole, in such a manner that it may be rotated approximately about its middle point and retained in one of two optional rotational positions on the pole, in which the pointed tip and the tip having the soft pad, respectively, are directed approximately in the longitudinal direction of the pole.
• the two tips are permanently fastened to the pole, by being situated on a common member, and the user may at choice change between using the one or the other of the tips, depending on the substratum.
• a covering element which can cover the pointed tip in this position, whereby it cannot cause any harm by unintentionally hitting persons or animals.
• the covering element may be adapted to be moved away from the covering position, in order not to prevent gripping by a hand the member on which the tips are situated during rotation of the member by change-over of the member.
• the covering element may be hinged to the end of the pole, in order to be pivoted between a position where it is swung in against the end of the pole and a position where it is swung out and covers the spike on the pointed tip when this is not in use.
• the covering element may have the shape of an arm, which has a hook-like portion on its free end.
• the end of the pole may be formed with means for holding the covering element close to the end of the pole when the covering element is not in use. These means may for instance be a pin adapted to be moved through a hole in the arm of the covering element.
• Another solution is that the end of the pole is formed with two pins with an interstice to which a portion of the arm of the covering element matches, whereby the arm will be clamped by being moved into the interstice.
• Other ways of fastening the covering element in the swung-up position are of course possible.
• the covering element in such a way that it stands permanently in the covering position, provided that it enables accomodation of the tip having the soft pad.

• Fig. 19 shows the embodiment of Fig. 18, seen from the side, having the spike directed downwardly and the covering element swung against the end of the pole.
• Figs. 18 and 19 may be combined with any of the other embodiments.
• the Figs show a device which, when being mounted lowermost on a pole may, by a simple grip, be varied between having a pointed and hard tip 2 and a thicker and soft tip 3, respectively, directed downwardly, i.e. in the direction of the pole.
• the two different types of tips are situated on a respective end of the same member 1 , this being coupled to the end 4 of the pole between the two types of tips and lies against an oblique plane on the end of the pole.
• This oblique plane may have any angle relatively to the axis of the pole, but the angle preferably lies between 30 and 60 degrees.
• the embodiments shown are such that the tip not being in a position of use is directed obliquely upwardly and oppositely of the walking direction. This is not a premise, but is supposed to be convenient. In particular when the pointed and hard tip is not in the position of use, it will not protrude to any side, and will to a small degree be able to hurt the user or others.
• the member 1 can be pivoted about the point of fixation for change-over with respect to which type of tip is to be in the position of use, and is kept in place against the end 4 of the pole by a retaining device. This is common to all the embodiments, which mainly depart from each other by the embodiment of the retaining device.
• the three embodiments shown mainly depart from each other with respect to how the member 1 can be locked against the end 4 of the pole and be released for being pivoted.
• All the embodiments comprise the member 1 having the two types of tips 2 and 3.
• the device may comprise some kind of a disc 5, in the form of a round or not round plate, as it best appears from the Figs. 5, 11 and 17, and which counteracts deep penetration in a soft substratum.
• the retaining device in the embodiment shown in the Figs. 1 - 5 comprises a bolt 6 inserted in a bore 7 in the end 4 of the pole.
• a helical spring 9 which is in abutment against an annular flange 10 in the bore 7 and which affects the member 1 with a force against the end 4 of the pole, in that the bolt 8 is fastened in the member 1 by a screw 22.
• the member 1 must be able to be locked against pivoting in the two positions of use, which may be achieved by forming the member 1 with at least one protrusion on the surface facing the end 4 of the pole and a corresponding recess in the end of the pole, such as a rib which may enter a groove in the end of the pole, or oppositely, i.e. that the end of the pole is formed with a rib and the member 1 has a groove. In stead of rib and groove for instance pins and holes may be used.
• the member 1 is mounted for rotation on a pin 12 on the end 4 of the pole, as it appears from Fig. 7.
• a not shown screw keeps the member 1 against the end 4 of the pole.
• an end portion 13 of the pole protrudes down into a bore directed towards the tip 2 of the member 1 and prevents rotation thereof around the pin 12.
• the member 1 has a corresponding bore 23 directed towards the other tip 3, for insertion of the end portion 13 when the tip 3 is in the use position. This appears at best from Fig. 7.
• the end portion 13 is pulled out of the bore in the member 1 ; i.e. that the entire pole is pulled upwardly relatively to the member 1 and the end 4 of the pole.
• the end portion 13 has knobs 14 which can be shifted in slits 15 in the end 4 of the pole.
• the slits 15 limit the shifting, whereby is prevented that the pole is pulled completely loose from the end 4 of the pole.
• the slits 15 have a restriction near the lower end, whereby a not complete circle is formed, into which the knobs 14 fit.
• the restrictions prevent the knobs 14, and thereby the pole, from being moved relatively to the member 1 during normal use. In order to permit movement of the pole and the member 1 apart from each other, these must be pulled apart manually, whereby the knobs 14 pass the restrictions.
• one slit and one knob may be used, but the connection becomes more safe by use of two slits and two knobs diametrically opposite of each other, as it appears from Fig. 10.
• the end 4 of the pole is a separate element, and comprises a sleeve threaded onto the end portion 13 of the pole.
• the end portion 13 of the pole protrudes down into the bore of the member 1 which is parallel to the pole. This prevents the member 1 from rotating.
• the entire member 1 and the end 4 of the pole must be shifted relatively to the remainder of the pole. Then, the end portion 13 of the pole will be pulled out of the bore in the member 1 , and the member may be rotated freely.
• the member 1 and the end 4 of the pole are shifted towards the remainder of the pole until the knob 14 passes the restriction of the slit 15.
• the end 4 of the pole has a corresponding rib 11 as shown in Fig. 2.
• the member 1 has a corresponding groove, into which the rib 11 fits, and the member 1 is in abutment against the oblique plane on the end 4 of the pole.
• a protruding pin 16 is provided on the member 1, as shown in the Figs. 13 and 16. Almost at the top of the pin 16 is an annular groove 17.
• the pin 16 extends into a throughgoing, oblique passage 18 in the end 4 of the pole.
• a pivotally mounted clamping bail 19 having a lever 20 (Fig. 16) extending downwardly and into a recess, obliquely from above.
• Lowermost this lever 20 has a bead 21 which fits into the circumferential groove 17 of the pin 16.
• the end 4 of the pole may in the embodiment shown in the Figs. 1 - 5 and 12 - 17 be the actual end of the pole, but it may also be a separate element fastened to the remainder of the pole. In the embodiment shown in the Figs. 6 - 11 the end 4 of the pole is a separate element through which the end portion 13 of the pole extends.
• a covering element may be provided on the end 4 of the pole, consisting of an arm 23 and a hook 24, for covering the spike on the pointed tip when the spike is directed upwardly.
• Fig. 18 shows the covering element in the active position
• Fig. 19 shows the covering element 23, 24 in the passive position, pivoted against and locked to the end 4 of the pole.
• the covering element 23, 24 may be hinged to the end 4 of the pole, in order to be pivoted in against the end 4 of the pole and be locked thereto.
• the locking may for instance be effected by a pin 25 on the end 4 of the pole, fitting into a narrow hole in the arm 23, or there may be two pins on the end 4 of the pole, having an interstice into which a portion of the arm 23 may be inserted and clamped.
