Description

The invention relates to a resilient ski pole grip, in particular for cross-country skiing, which is fastened to the upper end of the ski pole and whose ski pole grip body is displaceable against a spring made of rubber or plastic and formed as a tension spring in the direction of the ski pole tip towards the ski pole tube, arranged between the ski pole grip body and the ski pole tube.

A number of resilient ski pole handles are known in the prior art. For example, a resilient ski pole grip is known from German patent specification 605 168, inside which a helical spring is provided, which is supported on the one hand on the ski pole grip and on the other hand on the ski pole body, the ski pole grip, comprising the upper end of the ski pole body, along this upper end against the spring force is telescopically displaceable towards the top of the ski pole. A similar resilient ski pole handle, which is also guided on the ski pole body and can be displaced in the direction of the ski pole tip against the force of a helical spring, is known from German Offenlegungsschrift 2 107 075. However, these two resilient ski pole handles have the disadvantage in particular that the ski pole is shortened when the pole is used and that additional force is required to guide the ski pole, since telescopic guidance of the ski pole handle on the body or tube of the ski pole necessarily requires a certain amount of play and so that there is a tendency for these two parts to wobble relative to one another, which must be compensated for during the telescopic displacement.

Furthermore, a resilient ski pole grip is known from German laid-open specification 2518425, which is made entirely of rubber-elastic material. In a number of the described embodiments, this ski pole grip is attached with its upper end to the upper end of the ski pole, but its body can stretch elastically in the longitudinal direction. However, such a stretching necessarily means that the ski pole grip is deformed by making it longer and thinner, which is uncomfortable and irritating for the user. In another embodiment, between that of relatively inelastic material, e.g. Plastic, manufactured ski pole grip body and the ski pole tube in recesses of the former elastic rings or rolling elements, eg. B. in the form of O-rings, used so that they are elastically deformable and are under a certain pressure between the ski pole grip body and the ski pole tube. When the ski pole grip body is loaded by a force acting in the direction of the ski pole tip, the elastic rings located between the ski pole tube and the ski pole grip body, preferably made of an elastomeric material with good damping properties, are rolled or shifted between the aforementioned two parts. When the force decreases, the elastic rings should push the ski pole grip body up again. Apart from the fact that here, too, a disadvantageous shortening of the ski pole during pole use, already discussed above with reference to German Offenlegungsschrift 2 107 075, this type of suspension can only be used for very short displacement paths, because otherwise the ski pole grip body would not automatically re-adjust due to the rings would be pressed at the top, because the latter assumes that these rings do not roll off completely, but only a certain amount of “twisting”, since this configuration only provides an elastic restoring force. In one embodiment described in German Offenlegungsschrift 2518425, an elastomer body acting as a spring is clamped as a damping element between the upper inner end of the ski pole grip body and a stopper provided in the upper end region of the ski pole tube by means of a screw. Here, too, there is an already discussed disadvantageous shortening of the ski pole when using the pole.

Finally, a springy ski pole grip is known from German Patent Specification 1 157 982, which is fastened to the upper end of the ski pole and whose ski pole grip body can be displaced against a spring arranged between the same and the ski pole in the direction of the pole of the ski pole. This ski pole grip has a cavity in which a cylindrical helical compression spring is arranged, which, with its lower end supported on the shaft of the ski pole, gives the grip or a sleeve of the grip a suspension acting in the longitudinal direction of the ski pole, the suspension in the cavity elastic material, e.g. Rubber, existing sleeve embedded compression spring on which it is slidingly guided through the ski pole shaft. This ski pole grip also has the disadvantage, already explained above in connection with German laid-open specification 2518425, that it deforms in an unpleasant manner when used and that its stroke is also limited.

Finally, from German published patent application 2 704 751 a ski pole handle of the type mentioned is known, in which the suspension consist of rubber and can be designed as a tension spring. Thanks to its resilient resilience, this ski pole grip should reduce or almost exclude the risk of injury to the skier in the event of a collision with the ski pole grip. However, this ski pole grip should normally be locked against the ski pole when in use. If, on the other hand, one would use this ski pole grip without locking, then the same disadvantages would result as described above with reference to the German laid-open specification 2107 075, namely a shortening of the ski pole when using the pole and the need for an additional manager.

With the present invention, a resilient ski pole grip of the type mentioned is provided, which is displaceable against spring force, whereby the energy stored during use of the ski pole can be used for propulsion, and which ensures a soft pole insert without the ski pole grip body being used when in deformed in an uncomfortable manner and without a shortening of the ski pole and the above-mentioned guidance problems occurring, the lifting movement of the ski pole grip also being practically unlimited.

The resilient ski pole grip, which is provided with the present invention, is characterized according to the invention in that the suspension in the form of cords is attached to the upper ski pole grip attachment, which runs through the ski pole grip body in the direction of the ski pole tip and at the lower end of the ski pole grip body are connected to this.

With such a construction, the advantages mentioned above are achieved, namely that the ski pole handle according to the invention also has the advantages that the built-in spring parts, which are designed as rubber or plastic cords, act when pulled, that gradations of the spring force are possible in a simple manner that the ski pole handle as ready-to-use device can be manufactured and does not have to be specially adapted to each ski pole, but in the simplest way on any suitable ski pole, e.g. can be attached using a screwdriver; that the spring parts, namely the rubber or plastic cords, are easily and cheaply available, that the ski pole grip is light in weight, that the spring travel is very long and therefore the stored energy is high and that finally a loop can be attached to the ski pole grip body follows the movement of the same.

A further development of this resilient ski pole grip is characterized in that the upper ski pole grip attachment is a component that can be expanded by a screw inside the ski pole, through which an upper fastening part, on which the rubber or plastic cords are attached, rests on the upper pole of the ski pole, and one through an elastic disc and an elastic cone or calotte body are formed recoil damping.

This recoil damping reduces the impact of the ski pole grip body on the upper fastening part, in particular when the ski pole tip slips on ice or a stone or, in the case of the use of the ski pole grip according to the invention, on a ski roller stick (on asphalt or another ski roller track).

Another development of the invention is characterized in that only a few rubber or plastic cords are attached to the upper fastening part which is fixedly attached to the upper end of the ski pole tube, while the upper ends of the other rubber or plastic cords are attached to separate switches which can optionally be brought into a first position in which they are supported on the stationary upper fastening part during a relative movement of the ski pole grip body, and in a second position in which they are released from the stationary upper fastening part and can be moved on a movable part attached to the upper end of the ski pole grip body Support the fastener and take it with you.

The possible connection or disconnection of rubber or plastic cords in this further development is particularly important in cross-country skiing since, for example, different propulsion requirements result from double-deck use than from diagonal steps. While cross-country skiers exert a comparatively high pressure on the ski pole handle in the direction of the top of the ski pole when using the double pole, so that the strongest possible suspension should be available to use this high compressive force, the use of the diagonal step technique is the same when using the pole The pressure force exerted on the ski pole handle in the direction of the ski pole tip is significantly lower, since in diagonal step technology the most thrust occurs through the legs for reasons of balance and rhythm, so that a part of the rubber or plastic cords is deactivated in response to this lower force can be.

A particularly practical embodiment of this ski stick handle, which can be switched in its suspension, is characterized in that the changeover switches are essentially T-shaped, their longitudinal webs, to which the upper ends of the other rubber or plastic cords are fastened, together with the latter in each case in one The longitudinal direction of the ski pole fits through the recess passing through the stationary upper fastening part and its transverse webs can be pivoted into a first position in which they are located above the stationary upper fastening part and in a second position in which they are located laterally next to the stationary upper fastening part. With such a design, it is relatively easy to actuate the change-over switch, in particular when the change-over switch or its crossbars in the second position project laterally beyond the circumference of the ski pole grip body and / or the movable upper fastening part. The feature according to which the changeover switches are essentially T-shaped also includes designs of the changeover switches in which the longitudinal web of the T-shape is relatively short and / or in which the crossbar is relatively large and in its shape, for example, triangular, semicircular or . Like. is so that it can be used particularly well as an actuating element, which is actuated, for example, with the thumb of the user.

Preferably, the resilient ski pole handle, which is switchable in its suspension, is further designed such that the edge of the fixed upper fastening side has an increase on one or both sides next to the recesses, which preferably extends obliquely towards the upper surface of the fixed upper fastening part, on which it in the first position of the switch facing edges of their transverse webs a complementary bevel is provided. This prevents the changeover switch from accidentally being able to come loose from its support engagement with the stationary upper fastening part during the relative movement between the ski pole grip body and the ski pole tube due to vibrations or the like, in particular when the ski pole tip slips.

So that a particularly easy operation of the changeover switch is possible without interrupting the cross-country skiing of the user, the design can be such that the changeover switch is supported in its first position on the movable upper fastening part when the latter is in contact with the stationary upper fastening part, and only then After starting the relative movement between the ski pole grip body and the stationary upper fastening part, support the latter. With this design, the operation of the changeover switches is not made more difficult by the fact that they are in firm pressure engagement with the fixed upper fastening part, and as a result, these changeover switches can be tilted very easily from the first to the second position and vice versa, since they do not work in the latter case either must be pressed into pressure engagement with the fixed upper fastening part.

In some cases, for example when the cross-country skier using the resilient ski pole grip has to overcome a steep climb, especially in the grazing step, it may be extremely desirable that the suspension effect be switched off. Another development of the invention is therefore characterized by a fixing device for locking the ski pole grip body relative to the ski pole tube.

A particularly preferred embodiment of this type is characterized in that the fixing device comprises a locking part with a double wedge-shaped crossbar, which is displaceably attached to the ski pole grip body in the longitudinal direction thereof and is in a first position in braking or locking engagement with the ski pole tube or a brake lining provided on the latter , while in a second position it releases the relative movement between the ski pole tube and the ski pole grip body by means of a lifting wedge provided on the outside of the ski pole grip body. This embodiment of the fixing device has the particular advantage that it can be actuated easily and quickly by the user with a thumb push without interrupting cross-country skiing. The resilient ski pole grip according to the invention is not only suitable for cross-country skiing, but also for ski roller training, and in this latter case the resilient ski pole grip according to the invention can be supplemented by a ski roller pole tip at the lower end of the ski pole tube, in which the lower end part of the ski pole tube in it Is guided in a longitudinally displaceable manner and is held in a first position by a resilient, resilient at a predetermined pressure force acting in the direction of the tip end and a return spring from which it can be moved so far in the direction of the tip end when the predetermined pressure force is reached that it strikes the tip of the roller skate. This prevents or at least reduces the tip of the roller skate from slipping off the runway, since the blow that is applied drives the tip a little into the surface of the runway.

Reference is first made to FIGS. 1 to 3, in which an embodiment of a resilient ski pole grip, which is denoted overall by 1, is shown. This resilient ski pole handle 1 is together with a partly shown ski pole tube 2, which forms the main body of a ski pole, in particular for cross-country skiing, illustrated and attached to the upper end of the ski pole 3.

The main parts of the resilient ski pole grip 1 are one or more elastic or elastic cords 4 which are resilient in the longitudinal direction and which are fastened on the one hand to an upper fastening part 5 and on the other hand to a lower fastening part 6, and a ski pole grip body 7 which extends in the longitudinal direction between the upper fastening part 5 and the lower fastening part 6 extends. The upper fastening part 5 is fixedly attached to the upper ski pole end 3 via an upper ski pole grip fastening, which is explained in more detail below, while the lower fastening part 6 is attached to the lower end of the ski pole grip body 7; the lower fastening part 6 can also be formed in one piece with the ski pole grip body 7.

Preferably, the upper and lower fastening part 5 or 6, as can be seen particularly clearly from FIG. 1, is designed as a cap which comprises an annular part 8 and a tubular part 9 which is integral and concentric therewith. The annular part 8 has holes 10 evenly distributed over its circumference, the number of which is equal to the number of strands of rubber or plastic cords 4 which run between the upper and lower fastening parts 5 and 6, respectively. The holes 10 of the upper and lower fastening part 5 and 6 are aligned with each other in the longitudinal direction of the ski pole grip body 7, so that between each hole 10 in the upper fastening part 5 and the hole 10 in alignment with it in the lower fastening part 6, a strand of a rubber or plastic cord 4 runs. These strands can be formed by a single continuous rubber or plastic cord 4, as can be seen from the view in FIG. 2, after which the rubber or plastic cord 4 in this embodiment meanders between the upper and lower fastening parts 5 and 6 back and forth is led; its two free ends, which are not shown in the drawing, are firmly connected to one another, for example by knotting, a connecting part or in some other suitable manner.

The outer diameter of the annular part 8 is equal to the outer diameter of the ski pole grip body 7, which is preferably designed as a tube. The inner diameter of the annular part 8 of the upper fastening part 5 is smaller than the outer diameter of the ski pole tube 2, so that it rests on the upper pole pole end 3, whereas the inner diameter of the annular part 8 of the lower fastening part 6 is somewhat larger than the outer diameter of the ski pole tube 2. The inside diameter of the tubular part 9 is a little larger than the outside diameter of the ski pole tube 2, so that this tubular part 9 serves as a guide on the ski pole tube 2.

The ski pole grip attachment provided at the upper end of the ski pole grip 1 comprises, in addition to the upper fastening part 5, a cylindrical component 12 that can be expanded by a screw 11 inside the ski pole tube 2, the outer diameter of which in the unexpanded state is approximately equal to the inner diameter of the ski pole tube 2, and also one made of rubber or elastic plastic disc 13 and a rubber or elastic plastic cone or spherical cap 14. These components are arranged so that the upper fastening part 5 by means of the screw 11 between the upper end of the ski pole 3 and the expandable component 12 on the one hand and the disc 13 and the cone or spherical cap 14 is clamped on the other hand.

At the upper end of the ski pole grip body 7, a loop, not shown, is fastened, as is common with ski poles.

The mode of operation of the resilient ski pole handle 1 is as follows: when the pole is used, the strands of the cord 4 are stretched by moving the ski pole handle body 7 together with the lower fastening part 6 in the direction of the arrows A. This energy is released when the ski pole is lifted off and can be used as propulsion. The resilient ski pole grip is particularly suitable for Nordic competitive sport as well as for roller skate training, whereby in the latter case there is also a softer stick use than usual. The disc 13 made of rubber-elastic material and the cone or dome body 14 also made of such material cause a certain amount of recoil, so that the impact of the ski pole grip body 7 on the upper fastening part 5 during the backward movement of the ski pole grip body 7 into its rest position shown in FIG. 1 , in which it is held resiliently by the strands of the rubber or plastic cord on the upper fastening part 5, is damped.

Reference is now made to FIGS. 4 to 7, in which a resilient ski pole handle is shown, the suspension of which can be adjusted.

This resilient ski pole grip, designated overall by 15, comprises as main parts an upper ski pole grip attachment 16, which serves to fasten the resilient ski pole grip 15 at the upper end of a ski pole tube, not shown in FIG. 4, and on which the upper ends of the strands of one or several elastic or longitudinally stretchable rubber or plastic cords 17, 18 are attached. This upper ski pole grip attachment 16 corresponds to components 5 and 11 to 14 of the exemplary embodiment according to FIGS. 1 to 3, which form the upper ski pole grip attachment there. Furthermore, the ski pole grip 15 has a lower fastening part 24a, to which the lower ends of the strands of the rubber or plastic cords 17, 18 are fastened and which is attached to the lower end of a, preferably tubular, ski pole grip body 19, which in turn is located between the upper ski pole grip fastening 16 and the lower fixing part 24a extends in its longitudinal direction.

Apart from the fact that the lower fastening part 24a is in contrast to the embodiment 1 to 3 with its tubular part 20 encompasses the ski pole grip body 19 at its lower end and that there is no recoil consumption by omitting the components 13 and 14 and the attachment of the ski pole grip 15 by a transverse screw 21 and one into the interior of the upper ski pole tube end 3 engaging, non-expandable cylindrical pin 22, the essential structural modification, by means of which an adjustment of the suspension is achieved, compared to the embodiment according to FIGS. 1 to 3, is as follows:

Instead of the upper fastening part 5 of the embodiment according to FIGS. 1 to 3, a fastening device for the upper ends of the strands of the rubber or plastic cords 17, 18 is provided, which consists of a stationary upper fastening part 23, which via the screw 21 and the pin 22 is fixedly attached to the upper end of the ski pole, and from a movable upper fastening part 24, which is attached to the upper end of the ski pole grip body 19 and together with this in the direction of arrows A, ie in the longitudinal direction of the ski pole, can move; and finally the fastening device comprises parts referred to as change-over switch 25, which can be brought into support engagement either with the fixed upper fastening part 23 or with the movable upper fastening part 24 by a tilting movement of approximately 90 °.

Holes 26 are provided in the fixed upper fastening part 23, which are aligned in the longitudinal direction of the ski pole grip body 19 with corresponding holes 27 in the movable upper fastening part 24 and in the lower fastening part 24a, which is designed in the same way as the movable upper fastening part 24. A rubber or plastic cord 17 passes through two holes 26 in the stationary upper fastening part 23 and the holes 27 aligned therewith in the movable upper fastening part 24 and the lower fastening part 24a, which therefore forms two strands, the lower ends of which are on the outside of the lower one Fastening part 24a are connected to one another by means of clamping eyes 28 or in some other way. As a result, the strands of the rubber or plastic cords 17 are fastened on the one hand to the fixed upper fastening part 23 and on the other hand to the lower fastening part 24a and run loosely through the holes 27 of the movable upper fastening part 24. These rubber or plastic cords are therefore always elastic resistances during movement the unit consisting of the ski pole grip body 19 and the two fastening parts 24a and 24 is effective relative to the fastening part 23.

In contrast, two further rubber cords 18 are each pulled through holes 29 in the switches 25, and the two strands of these rubber cords 18 each extend through two holes 30 in the two fastening parts 24 and 24a and are also through clamping eyes 28 or in some other way on the outside of the lower fixing part 24a connected to each other.

The holes 29 are provided in the longitudinal webs 35 of the T-shaped change-over switch 25, and these longitudinal webs 35 together with the rubber cord 18 passing through fit into corresponding recesses 31 axially passing through the fixed upper fastening part 23, one of which each has approximately two holes 30 of the two fastening parts 24a and 24 are aligned. The upper, outer edges of the fastening part 23 on both sides of the recesses 31 have elevations 32 which are beveled towards the top of the fastening part 23. Complementary bevels 33 are provided on the outwardly directed lower edges of the transverse web of the T-shaped changeover switch 25.

The operation of the ski pole handle 15 is as follows: When the changeover switches 25 are in the horizontal position shown in the drawing, i.e. their transverse webs 34, seen in the longitudinal direction of the ski pole grip, run next to the fastening part 23, then they are supported only on the movable upper fastening part 24. As a result, when the ski pole grip body 19 is moved together with the fastening parts 24a and 24 in the direction of the arrows A, the longitudinal webs 35 of the changeover switch 25 move out of the recesses 31, together with the movable fastening part 24, on which they are pulled by the rubber cords 18 are held in the direction of arrows A. Since the rubber or plastic cords 18 are not stretched during this movement, they are to a certain extent ineffective, and then only the rubber or plastic cords 17 act in the manner shown in the exemplary embodiment according to FIG. 1 to 3 described way as the rubber or plastic cords there 4th

If, on the other hand, the changeover switches 25 are rotated upwards by 90 ° from their position shown in the drawing, so that their transverse webs 34, viewed in the longitudinal direction of the ski pole grip, are located above the fastening part 23, then the changeover switches 25, if those from the ski pole grip body and the fastening parts 24a and 24 existing unit is moved in the direction of arrows A away from the fastening part 23, retained by the latter by their transverse webs on the top of the fastening part 23 are supported on both sides of the recesses 31. As a result, the rubber or plastic cords 18 are stretched and are therefore effective together with the rubber or plastic cords 17.

As can be seen from this mode of action, the movable upper fastening part 24 is not used directly for fastening the rubber or plastic cords, but only for the optional indirect fastening of the rubber or plastic cords 18 by optionally supporting the changeover switch 25 on its upper side.

So that the pivoting of the switch 25 from its vertical to the horizontal position and vice versa as easily and quickly as possible tels thumb pressure can be effected without the user interrupting his running, the longitudinal webs 35 are so long that they initially in the vertical position of the switch 25, ie when the fastener 24 rests on the underside of the fastener 23 on the fasteners 24 support and the crossbars run at a certain distance above the top of the fastening part 23 and the bevels 33 are not engaged with the ridges 32. Since the lower ends are flattened in accordance with 36 of the longitudinal webs 35, results in a stable vertical position of the switch 25. When this support of the lower ends 36 thereof on the mounting part 24 during the downward pulling lifted together with the Skistockgriffkörper 19, the _vertical position is the switch 25 is stabilized by engagement between the elevations 32 and the bevels 33, so that the switch 25 cannot tip out of the recesses 31 during this relative movement between the fastening part 23 and the unit consisting of the ski pole grip body 19 and the fastening parts 24a and 24.

It should be noted that the cap-shaped fastening parts 24a and 24 are detachably or firmly attached to the ski pole grip body 19, for example by friction locking, by positive locking or by other fastening, such as, for. B. gluing, welding or the like.

The rubber or plastic cords 17, 18 are in the rest position of the ski stick handle, i.e. when the fastening part 24 is in contact with the fastening part 23, slightly tensioned, so that the abovementioned system is maintained by the slight tensioning of the elastic cords. The same applies to the exemplary embodiment according to FIGS. 1 to 3, in which there is also a slight tension of the rubber or plastic cords 4 in the position shown in FIG. 1 in order to hold the ski pole grip body 7 in contact with the upper fastening part 5. The ski pole grip body 7 or 19 can therefore only be moved in one direction relative to the upper fastening part 5 or 23 from its rest position, the overall length of the ski pole not being changed. A loop 38 of a conventional type, which is indicated in FIG. 5, is fastened to the ski pole grip body 19 and / or to the fastening part 24, so that it can move together with the ski pole grip body 19 in the direction of arrows A relative to the fastening part 23 and the ski pole tube, For which movement the fastening parts 24a and 24 form guides, since their central holes 37 have only a slightly larger diameter than the outer diameter of the ski pole.

8 to 11 show three different embodiments of a fixing device with which the user can lock the ski pole grip body relative to the ski pole if for any reason he desires that the rubber or plastic cords are all rendered ineffective and the ski pole is like a normal ski pole immovable handle is usable. This fixing device consists, according to FIG. 8, of a webbing 39, optionally attached to the ski pole grip body 19 via the loop 38, which has an eyelet or a hole (not shown in the drawing) with which it can be hung in a bolt 40, which is fixed is provided on the stationary upper fastening part 23, the eyelet or the hole being of course arranged such that the webbing 39 is taut when it is hooked in. If you want to loosen the webbing 39 from the bolt 40, you can do this simply by thumb thrust.

9 and 10 consists of a detent 41 which is attached to the free end of a webbing 42, the other end of which is attached to the ski pole grip body 19. This catch 41 has a handle part 43 and a pin 44, which can be inserted into a corresponding hole (not shown in the drawing) in the fixed upper fastening part 23 and is somewhat thickened at its lower end, so that it is elastic in the lower end thereof Lochs, which is correspondingly slightly expanded, can snap in which state the webbing 42 is taut.

In Fig. 11 an embodiment of a fixing device is shown, which can be called a double wedge brake, which has a substantially T-shaped locking part 45, the transverse web, which extends in the axial direction of the ski pole tube 2, a front wedge-shaped part 46 and a rear wedge-shaped Part 47 has. The locking part, the longitudinal web 48 of its T-shape as an operating handle protrudes through a slot 49 formed in the ski stick handle body 7 in the axial direction of the ski stick and which, apart from the point at which it passes through the slot 49, is wider than the latter, can be along the Slit 49 are moved. In its upper end position, it engages with a brake lining 50 fastened on the ski pole 2, for example by gluing, so that the ski pole grip body 7 is thereby locked on the ski pole 2. In its lower position, the web 48 runs onto a U-shaped lifting wedge 51 fixed to the side of the lower end of the slot 49 by gluing or in some other way attached to the outside, as a result of which the locking part 45 is held in the lower position. Since the locking of the ski pole grip body 7 on the ski pole tube 2 takes place in its upper position and this ski pole grip body 7 can only be moved downwards from this position relative to the ski pole tube 2, with reference to FIG. 11, the locking part 45 cannot engage the brake pad during this movement 50 occur when it is in its lower position, rather it is necessary to move the locking part 45 by thumb pressure along the slot 49 into its upper end position when the ski pole grip body 7 is in its uppermost position, as shown in FIG. 1 is shown. The braking effect of the brake pad 50 can be influenced by appropriate selection of the same or by roughening. Because of the wedge-shaped parts 46 and 47, the brake pad 50 can optionally also be omitted, so that the locking part 45 engages directly with the ski pole tube 2, in which case its surface is expediently roughened at the point of engagement.

Of course, the various embodiments of the fixing devices can be used both in the embodiment of the ski pole grip according to FIGS. 1 to 3 and in the embodiment according to FIGS. 4 to 7.

The resilient force with which the ski pole grip body 7 or 19 is pulled downwards relative to the upper end of the ski pole when the pole is in use can also be used to strike the ski pole tip by causing the ski pole tip to slide off the runway when a ski roller pole is used is prevented or at least reduced. Such an embodiment is shown in FIGS. 12 and 13 and is in principle such that the ski pole tube 2 is displaceably or telescopically mounted in the tip of the ski roller stick 52 and is supported with its lower end 53 on a locking device which, for example, comprises holding clips 54 , wherein this locking device is designed such that it releases the lower end 53 of the ski pole tube 2 at a predetermined, downward pressure, which in turn is displaceable to such an extent that this lower end 53 hits the inside 55 of the ski roller pole tip head 56; this impact drives the pointed end 57, which consists, for example, of a sharpened hard metal pin and is firmly inserted into the ski stick tip head 56, into the surface of the runway and thereby prevents the tip of the ski stick from sliding off.

Specifically, the retaining clips 54 are approximately L-shaped and are fastened diametrically on the outside of the roller skate stick tip 52 by means of disc springs 58 and a screw-nut arrangement 59 such that the transverse web 60 of the L-shape, which runs somewhat obliquely downward, is secured by a lateral one Slit 61 protrudes into the cylindrical interior of the roller skate tip 52, the side walls of which serve as a guide for the lower end part of the ski pole tube 2. At a predetermined force of the lower end 53 of the ski pole 2 on the crossbars 60, these are pressed against the force of the plate springs 58 and the ski pole 2, which has a slot 62 in the area of the continuous bolt of the screw-nut arrangement 59 , can move down to hit the inside 55. To return the ski pole 2, a coil spring 63 is provided, which acts between the continuous bolt of the screw-nut arrangement 59 and the bolt of a further screw-nut arrangement 64 provided in the ski pole 2. The upper end position of the ski pole tube 2 relative to the ski roller pole tip 52 is defined by the lower end of the slot 62, which comes into contact with the bolts of the screw-nut arrangement 59.
