Abstract
Description
- The present invention relates to a device for changing between two different tips on a pole.
- For poles used on varying substrata, as for instance asphalt, forest paths and snow/ice, it is an advantage to have a different tip when the substratum is soft, hard or slippy. For poles of the type Nordic Walking, i.e. for use on substrata without snow, this has been achieved by using a permanent, pointed tip in soft terrain and on ice. Additionally are used caps of rubber, which are threaded onto the pointed tips, and which are soft and have larger surfaces, in order to make it steadier to use the pole on hard substratum. The caps also damp the shocks transferred to the arms of the user when the poles are placed against the ground, and thereby reduses wear in joints. 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.
- Another solution is present on poles from 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. For soft substratum and ice 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. When the pole is used on hard substratum as for instance asphalt, 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. For use on hard substratum the spike may be moved as long upwardly in the pole that it does not protrude outside of the tip. For use on softer substratum or ice the spike may be moved out from the tip.US-A-3 738 674 shows a ski equipped crutch that converts from a skiing aid to a walking aid by rotating the ski having a skid resistant member. - 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.
- Thus, 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.
- Thus,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.
- When the member is rotated so that the pointed tip is directed upwardly, i.e. that the soft pad is directed downwardly and used, it may be an advantage that a covering element is provided 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. Moreover, it is possible to provide 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. - The embodiment of
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 andsoft 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 thesame member 1, this being coupled to theend 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 theend 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. - Thus, the three embodiments shown mainly depart from each other with respect to how the
member 1 can be locked against theend 4 of the pole and be released for being pivoted. All the embodiments comprise themember 1 having the two types oftips disc 5, in the form of a round or not round plate, as it best appears from theFigs. 5 ,11 and17 , 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 abore 7 in theend 4 of the pole. Below thehead 8 on the bolt 6 is ahelical spring 9, which is in abutment against anannular flange 10 in thebore 7 and which affects themember 1 with a force against theend 4 of the pole, in that thebolt 8 is fastened in themember 1 by ascrew 22. This appears from theFigs. 2 and 4 . - The
member 1 must be able to be locked against pivoting in the two positions of use, which may be achieved by forming themember 1 with at least one protrusion on the surface facing theend 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 themember 1 has a groove. In stead of rib and groove for instance pins and holes may be used. - In the embodiment shown in
Figs.1 - 5 rotation of themember 1 relatively to theend 4 of the pole is prevented in that theend 4 of the pole has arib 11 which protrudes into a corresponding groove in themember 1. In order to permit rotation of themember 1, this must be moved somewhat away from theend 4 of the pole, in a direction along the bolt 6, whereby the engagement between therib 11 and the groove is released. This movement takes place against the force of thespring 9. Themember 1 may be pulled, simultaneously with pushing against thehead 8 of the bolt 6, whereby thespring 9 is compressed further. When themember 1 has been moved out sufficiently to release therib 11 from the groove, themember 1 may be rotated 180° before it is slipped back into the groove and retained by means of the retaining device. - In the embodiment of the
Figs. 6 - 11 themember 1 is mounted for rotation on apin 12 on theend 4 of the pole, as it appears fromFig. 7 . A not shown screw keeps themember 1 against theend 4 of the pole. In the latched position anend portion 13 of the pole protrudes down into a bore directed towards thetip 2 of themember 1 and prevents rotation thereof around thepin 12. Themember 1 has acorresponding bore 23 directed towards theother tip 3, for insertion of theend portion 13 when thetip 3 is in the use position. This appears at best fromFig. 7 . In order to permit rotation of themember 1, theend portion 13 is pulled out of the bore in themember 1; i.e. that the entire pole is pulled upwardly relatively to themember 1 and theend 4 of the pole. As it appears from theFigs. 9 and 10 , theend portion 13 hasknobs 14 which can be shifted inslits 15 in theend 4 of the pole. Theslits 15 limit the shifting, whereby is prevented that the pole is pulled completely loose from theend 4 of the pole. - The
slits 15 have a restriction near the lower end, whereby a not complete circle is formed, into which theknobs 14 fit. The restrictions prevent theknobs 14, and thereby the pole, from being moved relatively to themember 1 during normal use. In order to permit movement of the pole and themember 1 apart from each other, these must be pulled apart manually, whereby theknobs 14 pass the restrictions. In the principle 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 fromFig. 10 . - Here, the
end 4 of the pole is a separate element, and comprises a sleeve threaded onto theend portion 13 of the pole. When themember 1 and theend 4 of the pole are positioned as far onto theend portion 13 as they are to be during use, i.e. when theknob 14 is in the lowermost portion of theslit 15, theend portion 13 of the pole protrudes down into the bore of themember 1 which is parallel to the pole. This prevents themember 1 from rotating. In order to change between the two tips, theentire member 1 and theend 4 of the pole must be shifted relatively to the remainder of the pole. Then, theend portion 13 of the pole will be pulled out of the bore in themember 1, and the member may be rotated freely. In order to lock themember 1 into place, themember 1 and theend 4 of the pole are shifted towards the remainder of the pole until theknob 14 passes the restriction of theslit 15. - In the embodiment of the
Figs. 12 - 17 theend 4 of the pole has acorresponding rib 11 as shown inFig. 2 . Themember 1 has a corresponding groove, into which therib 11 fits, and themember 1 is in abutment against the oblique plane on theend 4 of the pole. In the fixation point between themember 1 and theend 4 of the pole a protruding pin 16 is provided on themember 1, as shown in theFigs. 13 and 16 . Almost at the top of the pin 16 is anannular groove 17. The pin 16 extends into a throughgoing,oblique passage 18 in theend 4 of the pole. Circumferentially on the pole, above theend 4 of the pole, is a pivotally mounted clampingbail 19 having a lever 20 (Fig. 16 ) extending downwardly and into a recess, obliquely from above. Lowermost thislever 20 has abead 21 which fits into thecircumferential groove 17 of the pin 16. When the clampingbail 19 is loosened from the pole and is pivoted downwardly, thelever 20 having thebead 21 pushes the pin 16 downwardly and outwardly. Thereby, therib 11 on theend 4 of the pole is released from the groove in themember 1, and themember 1 may be rotated manually. When the rotation has been completed, the clampingbail 19 is moved back up against and fastened around the pole, whereby thelever 20 having thebead 21 moves the pin 16 upwardly and inwardly, in order to, in this manner, retain themember 1 against theend 4 of the pole, locked against rotation by the engagement between therib 11 and the groove in themember 1. - The
end 4 of the pole may in the embodiment shown in theFigs. 1 - 5 and12 - 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 theFigs. 6 - 11 theend 4 of the pole is a separate element through which theend portion 13 of the pole extends. - As shown in the perspective view of
Fig. 18 and seen from the side inFig. 19 , a covering element may be provided on theend 4 of the pole, consisting of anarm 23 and ahook 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, whileFig. 19 shows the coveringelement end 4 of the pole. The coveringelement end 4 of the pole, in order to be pivoted in against theend 4 of the pole and be locked thereto. The locking may for instance be effected by apin 25 on theend 4 of the pole, fitting into a narrow hole in thearm 23, or there may be two pins on theend 4 of the pole, having an interstice into which a portion of thearm 23 may be inserted and clamped.
