Description

Nordic walking stick

The invention relates to an improvement with respect to a stick. It particularly concerns a Nordic Walking pole. Sticks are equipped with a metal tip for their use on natural paths or gravel roads. These roads have no hard road surface. For their use on roads and paths with hard surface, e.g. with asphalt or concrete surface, they are to be equipped with a rubber cover. Such rubber pads or pads are placed on the lower end of the stick. They are usually plugged over the metal tip.

When changing the pad, it is therefore necessary to pick up the stick and remove the päd at the top or mount. During this manipulation of the stick, its pointed end sometimes comes at eye level. Since the pedestrian can only be pulled off from the tip of the stick with great force and, under certain circumstances, suddenly becomes detached from it, jerky movements of the stick with the bared metal tip can occur. It can thereby be e.g. Accompanying persons are injured.

The pads must first be changed from a storage location, e.g. a holder on the pipe or be retrieved from a bag. Then they must be plugged with force on the tip of the stick. At the next pad change they must be removed with force. After removal, they must be stored at the repository. In these actions, the pads must be taken in the hands. Therefore, a contamination of the hands must be accepted. In an adaptation of the pole tip to the road surface usually the pendulum behavior of the stick is influenced, which is not desirable. Because the presence or absence of the pad changes the weight distribution. Moreover, when the pawn is put on, the length of the stick is greater than when the pawn is not put on. Another disadvantage is that such pads are often lost if they are not attached as an active tip.

A disadvantage of such known pads is also that their grip and damping properties on hard surfaces are often insufficient. In order to improve the damping properties of Nordic Walking poles, pads have been developed which, thanks to cavities inside the pad, between the pads Support sole and the Rohraufnahniehlung bumps and bumps of the substrate elastically cushion (EP-A 1 541 053, DE-A 202004043 500). As usual, one foot of such pads extends from the intersection between the pole axis and the ground in the direction of travel both forward and backward.

Further disadvantages of previous pads are the soiling of the storage location, the effort required to remove and mount the pad, the time required for these actions, as well as the fact that the pedestrian is often incorrectly mounted.

It is known from DE-U-202005 000466 a stick is known in which the hard tip of the stick can be pushed out of the soft stick tip via an operating element.

From Norwegian patent no. 319884 is a device for

Switch between several tips of a stick known. In this, a rotation axis is provided on a tip body which extends at an angle of approximately 45 ° to the axis of a pipe receiving. At least two tips are arranged on this axis of rotation, which can be rotated by rotation about the axis of rotation in the tube axis and out of the tube axis. As disadvantages of this device are considered that the dirty tip needs to be touched when changing, that when changing the tips simultaneously both the fixation of the axle solved and the rotation must be made, and that is not excluded that the tip through the unintentionally twisted during use forces. Next is the one at the top of the

Stick device to be mounted much heavier than a normal tip with a stuck ped, which has a negative effect on the pendulum behavior of the stick.

The invention is based on such a stick, in which both tips remain in the area of the pole tip and can be changed according to the road surface.

It is therefore an object of the invention to propose an improved floor. The manipulation for the change of the tip for hard covering on a point for

Natural road or vice versa should be improved in a preferred embodiment of the stick. This object is achieved according to the invention by a stick according to claim 1. The preferred embodiment is defined in claim 3.

Such a pole comprises a tube which defines the pole axis. At the top of the tube, the stick has a handle. A hand strap is arranged on a first, with the stick with the stick backward side of the stick, the handle. At the lower end of the tube there is a stick tip with a pad having a support sole made of rubber or a rubbery material. The support sole of this pad touches the soil at the floor parked on the floor in total or in the course of a rolling successively. At the tip of the stick a hard tip is also arranged. Each of these tips is activatable.

According to the invention, the support sole of the activated pad lies to a greater extent on the second side of the stick, which is directed forward when walking. It is advantageously arranged at a distance from the pole axis. Thanks to the support sole of the pad lies in front of the pole axis, there is a leverage effect between the support sole and place of attachment of the pedestal on the stick. This leverage results in the removal of forces to a deformation of the pad transverse to this lever direction. This allows the pedestrian to cling to the ground. And thus he can also dampen the blows when striking the stick tip on the hard surface.

For this damping to be satisfactory, the average distance between the ground contacting pad and an intersection between the pole and the bottom is preferably greater than 1.5 cm. The maximum distance of the support sole to the interface between the pole axis and the ground should advantageously not be greater than 4 to 5 cm. The minimum distance can be between 0 and 1 cm. In other words, a preferred minimum distance between the pole axis and the support base measures between 0.3 or 0.5 cm, and a preferred maximum distance between 3.5 and 5 cm.

The stick also has a hard stick tip. The fact that the support sole is in the activated position essentially only on the second side of the stick, allows several easy change of position of the pole tips for switching between hard and soft pole tip. The change of position can be achieved by moving the hard or soft stick tip, or by twisting the hard or soft stick tip, or by turning both the hard as well as the soft stick tip done. A particularly preferred floor has at the tip of a stick a directed to one side of the stick ped and a directed to the opposite side, hard tip. Both the hard tip and the soft päd can be brought into contact with the ground by bringing the corresponding side of the stick forward, thereby directing the desired point downwards. In order to make this reversal of the stick, the hand strap and the pole tip are designed to be fixed in two relative to each other by, for example, 180 ° rotated positions. Such a rotation takes place about the pole axis.

The twist between the pole tip and the wrist strap can also make a smaller angle. Already at a rotation of 90 or 120 degrees, a first tip is sufficiently turned away from the active position, so that a second, after turning the ground facing tip of the first tip can be used without hindrance. In this manner, three or four tips may be formed on a stick tip, which may be selectively activated by a corresponding rotation of the stick. Examples of such tips are: a hard (eg metal) tip for gravel, earth or the like, an elastic harder point (Päd) for hard coverings, a shovel-like tip for sand (for beach runner), a tip (Päd) made of soft , elastic material for rocky, uneven surfaces, a point in which an elastic pad sole and metal tips are combined or in it, eg for use on hard-packed snow.

Even for only two peaks, the angle of rotation can be less than 180 degrees. The two tips may be at an angle of at least 90 degrees, e.g. 100 or 110 degrees, or 135 or 150 degrees to each other. The necessary rotation can be less than or greater than 180 degrees. An angle of 180 degrees is preferred because the center of gravity of the pole is then in a plane defined by the pole axis and the wrist strap.

In order to make such a rotation of the pole tip with respect to the loop, twists are conceivable at any point between the attachment point of the loop and the pole tip. Preferred are those places where the pole tip does not need to be taken in the hand.

In a first embodiment, the hand strap relative to the handle in two positions rotated relative to each other can be fixed. The rotation takes place between the hand strap and the whole handle. Pipe and stick tip are turned together with the handle. Thereby, the handle and the pole tip can be connected in a conventional manner with the tube. There are various ways to change the location of the hand strap on the handle. Advantageously, the hand strap is releasably connected to the floor and connectable to the floor on the first and on the second side of the stick. Such releasable compounds are known in the form of one-sided connection possibility. Some of these unilateral connections can be adapted in a very simple way for a two-sided connection. It needs, for example, a continuous, from. opening accessible to both sides of the handle, into which a plug-in part on the hand strap can be inserted into the handle. Inside the handle then a locking device is present, which fixes this part in the inserted position.

However, the wrist strap can also be permanently connected to the stick and be fixable in two positions with respect to a rotation about the pole axis relative to the stick.

If the hand strap can be fastened in two positions relative to the handle, the handle is advantageously designed to be symmetrical. The handle should be designed so symmetrical that the gripping of the handle from the two opposite sides is possible and conveniently equally comfortable. It is expediently symmetrical in that it has the same shape in both rotated by 180 ° to the hand strap positions at least in the region of a contact surface with the hand. Above this

Contact surface, the handle may be asymmetrical. This is for example the detection of the active in this position peak.

The hand strap may e.g. be arranged on a ring which is formed rotatable relative to the handle. This ring can be releasably or permanently connected to the handle. The wrist strap can also be designed to be rotatable about a pin arranged on the pole axis, or it can be hinged to the handle in the manner of a ball joint. It can also be provided on both sides of the handle depending on a separate attachment for the hand strap on which the hand strap, for example. can be hung.

In a second embodiment, an upper part of the handle, to which the hand strap is attached, opposite to a lower part of the handle with tube and Stick tip fixed in two relatively rotated positions. The lower part of the handle comprises in particular a contact surface for the hand. The rotation occurs somewhere between the attachment point of the hand strap and the contact surface for the hand.

In this embodiment, the lower part of the handle is preferably formed so symmetrical that it has the same shape in both positions. The upper part of the handle can also be formed symmetrically. However, it is advantageously formed asymmetrically with respect to a plane containing the pole axis transversely to the direction of movement and / or with respect to a plane containing the pole axis parallel to the direction of movement. Such asymmetries serve to better fit the handle to a hand.

In a third embodiment, the handle is twisted together with the hand strap opposite the tube with a stick tip in two relative to each other

Positions fixable. The rotation takes place between handle and tube. This makes it possible to freely form the handle, which leaves much room for an anatomical shaping of the handle. The rotation can also take place between an inner part of the handle and an outer part of the handle. The inner part of the handle can thus be non-rotatably attached to the tube and a

Include locking device with. Part between the tube and an inner handle, and / or between an inner and an outer handle, a length adjustment of the stick can be done.

In a fourth embodiment, an upper part of the tube with the handle and the hand strap is fixable relative to a lower part of the tube with the pole tip in two relatively rotated positions. The rotation occurs within a composite tube. The tube can be assembled on a joint perpendicular to the axis of the pole. It has in this case a gap bridging this gap or a core bridging this gap. At least the upper or the lower pipe section is rotatable relative to the bridging part. The tube may also be formed in two layers. Then the inner and the outer layer are rotated against each other.

In a fifth embodiment, the tube with the handle and the

Hand strap together with respect to the pole tip in two relative to each other to twisted positions fixed. The rotation takes place between tube and stick tip. The pole tip can be like conventional pole tips about 4 cm To be long. So that the position change can be made as possible without contamination of the hand in this solution, the pole tip, however, preferably has a shank area around the tube. This shaft region is for this purpose at least 6 or 8, preferably 10 to 20, particularly preferably 13 to 18 cm long. At this shaft region a locking device is formed. This, or the operating element is preferably arranged with the greatest possible distance from the pole tip.

The ped and the hard tip at the tip of the pole are fixable in a sixth embodiment in two relative to each other about the pole axis rotated positions relative to a pipe-mounted part of the pole tip. The rotation takes place within the tip of the pole between its attachment to the tube and the two different, individually activatable tips. In order to be able to change the active tip without soiling the hand, this embodiment is preferably combined with automatic rotation for the tip.

It is expedient to arrange a releasable locking device between parts that can be compressed relative to one another, which ensures that these parts can be fixed to one another in only two positions.

The locking device is advantageously designed such that it can be operated on the handle with the hand holding the handle. It can be operated, for example, with the entire hand, with the thumb or the index finger. The locking device may include an automatic rotation to increase comfort, which triggers a rotation of the two mutually rotatable parts upon actuation of the locking device.

Since the stick hardly has to absorb torques around the tube axis when it is being turned, a lock about this axis can also be formed in such a way that it can be released with an increased torque. The locking device is releasable in a preferred embodiment by applying a torque about the pole axis and engages in two, three or four positions. This can be achieved by two nested sleeves, in which in the inner sleeve, a compression spring is housed, which presses on both opposite sides each have a ball through a bore in the sleeve. The holes in the inner sleeve are dimensioned so that the balls can pass through. Axial to these holes are in the outer sleeve also provided holes. These holes in the outer sleeve have a smaller diameter than the holes in the inner sleeve and as the balls. The holes in the outer sleeve could be conical. The ball can only enter each hole. It then rests on the edge of the hole or on the bore wall.

By applying a torque around the tube axis to the two connected via the sleeves parts of the stick the sleeves are rotated against each other. In this case, the outer sleeve presses the balls against the spring force of the compression spring against each other until they are forced out of the bore. Now, the two sleeves can be easily turned against each other until the balls enter the next holes and are pressed by the spring force into the holes. In this position, therefore, the two sleeves snap. Are two opposing bores provided in the outer sleeve, the inner relative to the outer sleeve is rotatable by 180 degrees. If there are four holes, the two sleeves can be rotated by 90 degrees until they engage again.

Instead of two balls, only a single ball can be provided, wherein the compression spring absorbs this ball against the opposite wall of the inner sleeve. This is particularly advantageous if the tip is to be locked in three rotational positions relative to the handle.

Advantageously, the inner sleeve has a pawl for undercutting engagement behind the outer sleeve. As a result, the two sleeves can not be separated from each other, and yet are mutually rotatable about the tube axis. Advantageously, one sleeve sits in the handle and the other in the tube. To ensure that the end of the pipe is etched and protected from being broken, an edge is formed on the sleeve which is inserted in the pipe, which surrounds the pipe end and surrounds the pipe on the outside. The tube is therefore in an annular gap, in which it is glued. The outer sleeve is preferably in the grip. It can be glued in or simply plugged into the handle.

Such a stick may be telescopically variable in length and / or collapsible. The change in length is expediently designed only to correct a standard pole length to a length optimally adapted to the body size. A maximum change in length makes about 5 to 10 cm, or to 15 cm for this purpose. Such a device for length change is preferably integrated in the handle. The folding, however, serves to shorten the stick for the supply of the stick. The joint between two collapsible parts may be the location of twisting between the upper and lower parts of the stick.

The Päd is stuck in advantageous embodiments of a hard tip. The top passes through the päd attached. In this case, the pedestrian can be plugged in a conventional manner onto a base body of the pole tip, in which the metal tip is anchored. Preferably, the hard tip is arranged eccentrically or angled at the tip of the pole.

The pedestrian can also be arranged next to the hard point at the tip of the stick. Then, the pole tip in the main body has two formations for receiving a tip, namely a first formation for receiving a hard tip and a second formation for receiving a soft pad. These two formations for receiving stick tips are arranged, for example, in a plane containing the pole axis through the wrist strap, so that the center of gravity of the stick lies in this plane. Small deviations of the center of gravity of the stick from this plane are possible without disadvantage. Therefore, it is also possible to arrange more than two tips on a stick or on a main body of the pole tip.

The hard tip may be embedded in a soft rubber or rubbery material for shock absorption.

Preferred is an embodiment in which the hand strap on the handle and can be disengaged. For this purpose, a locking device is present in the interior of the handle. This can interact with a plug-in part on the wrist strap. The locking can be done by pressing the

Locking done by hand. The locking can also be done by a spring force that can be overcome by the action of force on the plug.

The invention also relates to a päd for putting on the tip of a stick. The ped has an axially extending pole top receptacle and a base of rubber or rubbery material. The foot has a support sole for contact with the ground. The pad is located at a distance to the axis of the receiving cavity for the pole tip. A longitudinal extent of the receiving sole is at an acute angle to this axis.

A final possibility of twisting about the pole axis results between the pole tip and the pedestrian. In this embodiment, the pedestal is rotated from a rear, deactivated position to a front, active position via the hard tip remaining in the active position. This rotation about the pole axis has the advantage that the hard tip also remains in use when the pedestrian is active. Under strong pressure on the type of activator activated in the described manner, the pedler gives way and the hard point comes into contact with the ground.

Instead of a twist between the wrist strap and the pole tip can be activated or deactivated by a displacement of the ped along the axis of the pedestrian. The pedestrian is e.g. attached to a shaft which can be locked against the tube in two positions. Advantageously, the shaft is also adjustable in its position, so that wear of the Päd can be compensated.

The last two variants are also combinable. The päd becomes one

Combination of these variants moved along the pole axis and at the same time rotated about the pole axis.

Regardless of whether or not the stick is designed according to the invention, it may be advantageous to coat the stick tip with a coating of elastic material, e.g. To provide rubber. This cover may be or include a bladder, especially around the hard stick tip. This cover may comprise a collar around the entire exterior of the plastic tip base member. The coating covers at least the metal tip to a substantial extent. Advantageously, with the coating of a rubber or rubber-like material and the päd together the outer surface of the base part (including hard tip) covered at least 90 to 95%. This measure serves to reduce the noise emission when the tip of the pole hits the ground.

The invention will now be explained in more detail with reference to the schematic drawings. It shows: 1 shows an inventive Nordic walking pole in an active position. Its inclination is between a position when putting the stick and a position when lifting the stick from the ground. The floor is equipped with a novel Päd.

The Nordic walking pole 11 shown in FIGS. 1 and 2 has a handle 13 with a hand strap 15, a tube 17 and a pole tip 19. The handle 13 has a contact surface 21 for one hand below the attachment point 23 for the hand strap 15. Above this attachment point 23, the handle has a knob 25, which serves, among other things, the leadership when tightening the stick.

The symbolically illustrated wrist strap 15 may be a known hand strap of any kind. The wrist strap 15 is necessarily arranged on that side of the handle 13, which is directed upwards and backwards when walking. This page is called the first page of the stick below. Opposite this first side of the hive is the second side of the hive, which must be directed downwards and forwards in order to be able to walk Nordic Walking with the hive.

At the tip of the pole 19, a tip base 31 made of plastic is placed on the tube tip. On the tip base 31, a rubber pad 33 is placed. At the top of the pole 19, a metal tip 35 is also present. The metal tip 35 is anchored in the tip base 31. Instead of a metal tip, for example, a suitable, hard plastic, ceramic, diamond inserts, etc. may be used. The inclination of the stick when putting the stick is about 60 to 70 degrees. The inclination of the stick after repelling and before lifting the stick is usually about 45 to 40 degrees. Within these angular degrees, ie preferably from 35 to 75 degrees, the stick must reliably remove the force to be transmitted to the ground.

For this purpose, the pole tip 19 is equipped with a peder 33 and a metal tip 35, from each of which the adjusted tip can be directed downwards. The orientation is effected by rotation of the stick 11 or parts of the stick about the pole axis 27. In Figure 1, the peder 33 is directed downwards and thus activated. Untergund 29 is therefore a hard surface. In Figure 2, the metal tip 35 is directed downwards. The substrate 29 is therefore a natural coating into which the metal tip 35 can penetrate.

In Figures 3 and 4, two rubber pads 33 are shown. In FIG. 5, such a rubber pad is shown mounted on a base part 31. The shape of these three pads 33 is different. However, the features described below are the same for all. The rubber pad 33 has a receiving cavity 41. The receiving cavity is axially formed. Mounted on the stick, the axis of the falls

Recording cavity with the pole axis 27 together. In this receiving cavity 41, the base part 31 of the pole tip 19 must be inserted. The rubber pad 33 stops at the tip of the pole 19 by friction between the base part 31 and the wall of the receiving cavity 41. It is also possible, in addition to the friction, to provide a positive connection between the pedestal and the base part of the pole tip. The hard tip 35 anchored in the base part must be pushed through the rubber pad 33. For this purpose, a passage opening 43 for the hard tip is formed in the peder 33.

At Ped 33 a foot 45 is formed. The foot 45 has a support sole 47. The support sole 47 may be curved, as shown in Fig. 5. The support sole 47 may be planar, as shown in Figures 3 and 4. The support sole can be structured in any case, as shown in FIG. 4 can be seen. The support sole 47 is at an acute angle to the axis of the Aufnahmehöhlung 41. It is clear from the use of a Nordic walking pole, in which

Direction such a foot 45 must be directed so that he can fulfill his task properly. The direction for mounting on the pole top 19 is also given by the passage opening 43 for the hard tip 35. In Figure 5, the conically shaped base portion 31 of the pole top 19 is clearly visible. In the base part 31, the metal tip 35 is anchored. It can be anchored in it rubber-encased. Around the base member 31 around the peder 33 is attached. The receiving cavity 41 is connected to the passage opening 43. The receiving cavity 41 fits on the base part 31 and holds it by friction, and possibly additionally positively locking. The support sole 47 shown in Figure 5 is curved. The support sole 47 therefore rolls in the course of the movement of the stick from initially up to 75 degrees of inclination to finally at least 35 degrees inclination over the length of the support sole from back to front. In contrast, in the case of the pads according to FIGS. 3 and 4, the entire support sole, or a substantial part of the support sole 47, rests on the whole. These pads 33 absorb the change in angle between the floor 11 and the floor 29 mainly by deformation of the foot 45. In practice, a mixed form of the two processes shown typically can occur. The ped is deformed and a rolling motion is superimposed on this deformation.

The pole tip 19 may also be formed differently than shown in Figures 1 to 5. Figures 6 and 7 show stick tips 19 with two separate Aufnahmeausformungen 51 and 53 on the base part 31. In the first

Aufnahmeausformung 51, the hard tip 35 is anchored. On the second Aufnahmeausformung 53 the peder 33 is attached.

FIG. 7 shows a pole tip 19 whose base part 31 has a shank region 55 which is relatively long with a length of, for example, 12 centimeters between the tips and the opening for the tube 17. In the shaft region 55, the tube 17 and the pole tip 19 are mutually rotatable connected to each other. With a locking button 57, the pole tip 19 can be fixed in two selectable rotational positions on the tube 17. This pole tip 19 may also be provided with additional openings 59 for the

Locking button be equipped so that the length of the stick can be adjusted.

So that the locking button 57 can reliably convey the forces occurring when using the stick 11 between the active tip and the shaft, it may be advantageous if the locking button 57 is arranged on a part of the pole tip fixed to the tube. The shaft portion 55 forms together with the Aufnahmeausformungen 51,53 a second part of the pole tip 19, which is opposite to the first, attached to the tube, rotatable.

In the figures 8 and 9 handles with hand straps are shown. In these, the hand strap can be fastened on two opposite sides of the handle. In FIG. 8, a hand strap 15 can be hooked into a hook 61. On both sides of the handle, such a hook 61 is formed. These hooks are closed with a locking pawl 62. Such a hook can be aligned in the vertical direction or in a horizontal direction, or in any other direction.

The handle 13 shown in FIG. 9 has an insertion opening 63 for a plug-in part 65 attached to the hand strap 15. An arresting device 67 is present in the interior of this insertion opening 63. This locking device consists for example in a pin 69 which can be pushed into an opening in the inserted plug 65. This pin 69 sits to slidably in the axial direction in the handle 13. Since the insertion opening 63 is formed continuously, the male member 65 can be inserted from both sides into the handle 13.

These two figures 8 and 9 illustrate in general that the loop can be attached to the handle from both sides. There is the possibility of attaching the hand strap two, i. to provide on each side one, or even a single locking device. It may be provided from the prior art known locking devices.

FIG. 10 shows a rotatable handle 13. With the operation button 71, the fixation of the handle 13 relative to the tube 17 can be solved. Thus, the handle is rotatable relative to the tube. He locks in one of two possible positions again. The loop 15 is always arranged on the same side of the handle 13. This embodiment has the advantage that the handle shape can be arbitrarily and therefore optimally adapted to one hand.

This advantage also has the embodiments shown in Figures 11 and 12. In these, an upper part 73 of the tube 17 relative to a lower part 75 of the tube 17 is rotatable. It is in the figures

Connecting parts between the pipe parts 73,75 shown, which have a larger diameter than the pipe 17. This is by no means a condition. The connecting parts reinforce the pipe in the area of the jointed place. They ensure that the two pipe parts 73,75 are fixed against each other only in two defined positions. If appropriate, as shown schematically in the exemplary embodiment according to FIG. 12, they also permit a length change of the stick. However, the connecting parts may also be formed in the interior of the tube 17.

The stick 11 can also, as shown in Figure 13, be formed kinkable. This allows the stick shortened e.g. in a backpack to provide. Such kinks 79 may also be present in a plurality. One of the kinks is in two different rotational positions, namely rotated against each other by 180 degrees, zusammenfügbar. The buckling can be done by pulling the tube 17. The upper part 73 and the lower part 75 of the tube are tied together with a spring means 77 (Figure 14). The spring means allows a pulling apart of the tube at the kink point 79. The exploded tube is no longer rigidly connected at the kink and can therefore be kinked.

The rigid connection of the tube in use condition is given by a sleeve 81 and an axial pin 83 which fits into the sleeve. The correct position of the two pipe parts to each other is given by positive locking. It is possible to fix the two pipe parts together with, for example, a bayonet lock. In this case, the bayonet lock is both the means for defining the two positions of use, as well as the connecting means. A spring means 77 can therefore be omitted. Instead of the bayonet closure also clamp closures or interconnection systems are possible.

In a bayonet fitting, it is expedient to provide a position in which the two pipe parts to be joined can be put together, and to activate the tips by opposite directions of rotation by 90 or 180 degrees. The bayonet lock is therefore closed from the neutral position in two directions of rotation.

The pole tip shown in Figures 15 and 16 has a base part 31. In the base part 31, the hard stick tip 35 is embedded. On the base part 31 sits a secondary part 91. This is relative to the base member 31 about the pole axis 27 rotatable. The peder 33 is attached to the secondary part 91 and is rotatable together with this about the pole axis 27. As a result, the pedestrian can be brought into an active position (FIG. 15) and into a passive position (FIG. 16). The pole tip shown in FIGS. 17 and 18 likewise has a base part 31 and a secondary part 91 arranged movably thereon. The secondary part is displaceably mounted relative to the base part 31. It can be displaced in the direction of the pole axis and thereby brought into an active position (FIG. 17) and a passive position (FIG. 18).

In addition to the displacement, a rotation may be provided (dotted Päd in Fig. 18). This displacement together with the rotation can be guided by a coarse thread. Such a solution can also be provided in order to be able to provide a central hard tip and two different pads on one pole tip. The pads can then be brought by the shift in the passive position, selected by rotation and pushed back into the active position.

In FIGS. 19 to 20, four different pole tips are shown by way of example. The pole tip shown in Figure 19 has, as mentioned above, three peaks in a plane. The hard tip 35 is immovably and non-rotatably anchored in the base part 31. Two pads 33 and 34 are disposed in confronting position. The pads 33,34 can be rotated on the one hand about the pole axis, and on the other hand moved along the pole axis. Moving the pads towards the handle activates the hard tip. By turning 180 degrees around the pole, one of the pads is selected. By shifting to the top of the stick, the selected pedestal 33,34 is activated.

In the case of the pole tip according to FIG. 20, the double pad 33, 34 together with the hard tip can be rotated in each case 120 degrees relative to the wrist strap. The pole tip 19 comprises three points, which can be selected by a rotation of 120 degrees each. The selected tip (e.g., 33) is disposed in an operative position opposite the wrist strap by this rotation, the other two tips (e.g., 34, 35) are angled rearwardly and can not contact the ground in that position.

In the case of the tip shown in FIG. 21, the pod 33 is opposite the hard tip 35 at an angle of approximately 135 degrees, or 225 degrees. There are two ways to turn the other tip into the active position. The rotation may have to make the larger or the smaller angle. In the figure 22, the illustrated stick tip has four peaks. These are by a 90 degrees. or a 180 degree rotation interchangeable. The rotation can happen at any point between the wrist strap and the stick tip. This stick top includes the hard metal tip 35, a hard peder 33 for roads, a soft pead 34 for rocky ground, and a shovel 36 for sandy bottom. The blade 36 may be formed integrally with the base part 31.

The rotary member 87 shown in Figure 23 consists of two sleeves. An inner sleeve 93 is inserted in an outer sleeve 95 and is rotatably mounted in this around the common pole axis 27. The outer sleeve 95 is adapted to be housed in the handle 13. Their outer surface is profiled according to a frictional engagement or formed correspondingly rough for an adhesive bond. The outer sleeve is formed as a tube and has only two holes at perpendicular to the tube axis opposite points of the tube.

Inside the outer sleeve 93 is an inner sleeve 95, which is made of a solid piece of metal, in particular aluminum, worked out. Alternatively, the inner sleeve 95 could also be an injection molded part made of plastic. The inner sleeve 95 has a handle-side end 97 which is inserted in the outer sleeve 95, and a tube-side end 99 which is glued into the tube. The handle-side end has a transverse bore, in which two balls 101 and a spring against each other resiliently supporting compression spring 103 are arranged. The transverse bore has a slightly larger diameter than the balls and the compression spring 103, so that they can move freely in the direction of the axis of the transverse bore. The handle-side end 97 also has latching spring arms 105 which engage behind the end of the outer sleeve 95 with a hook 107.

At the tube-side end of the inner sleeve 93, a ring 109 is integrally formed. An annular gap is formed between the ring and the tube part to be inserted into the tube. The ring is connected at the handle-side end of the annular gap via a collar closing off the annular gap with the part of the inner sleeve to be inserted into the tube. The pipe is to be inserted into this annular gap and stuck in it. The glue fills out the part of the ring gap that is not taken up by the pipe itself. As a result, a tube glued therein is firmly enclosed. Because for the tubes primarily fiber-reinforced plastic, In particular, carbon tubes, are used, this embracing the pipe end with the ring prevents a breakup of the fiber structure at the pipe end. This increases the resilience of the stick.

Mounted on the handle, only the ring 109 can be seen from the rotating part. All other parts of the rotary member 87 are arranged in the handle or in the tube. The balls 101 are therefore not visible and not accessible. The rotation of the tube relative to the handle therefore takes place only by applying a torque. As a result, the balls are pushed out of the holes in the outer sleeve and then roll on the inner surface of the outer sleeve, until they engage in a rotation of 180 degrees back into the holes. By choosing the bore size, the ball size and the spring force, the required torque for disengaging the balls from the holes is adjustable. The ratio of bore diameter and ball diameter determines the inclination of the ball surface to the contact surface or contact edge on the bore. In this case, lower necessary torques are obtained, the flatter this inclination. Conveniently, the dimensions are chosen such that the ball does not penetrate deeper into the outer sleeve, as the wall is thick, so that the balls are not present on the material of the handle.

The rotary part shown in Figure 24 differs therefrom by the following features. The tube-side end 99 of the inner sleeve 93 is not inserted into the tube, but includes this only. The handle-side end 97 is provided with an annular groove in which a clamping ring 111 is seated. This clamping ring 11 secures the inner sleeve before pulling out of the outer sleeve 95. The handle side

End 97 is made of solid material to form the annular groove therein, therefore, the bore for the balls 101 and the spring 103 is formed near the annular groove. The inner sleeve is hollow as far as possible.

The pole tip (base part 31) shown in FIG. 25 has the rubber pad 33 on a first receiving formation 53 and a hard tip 35 in a second receiving formation 51. The rubber pad 33 is pulled over the special, shaped footing 53 like a shoe.

At the rubber pad a bellows 113 is formed. This bellows is slipped over the hard tip 35 when coating the rubber pad. The hard tip 35 only looks very slightly out of the bellows. When using the hard tip of the bellows is forced back as needed by the ground and thereby folded. Such or similar coating over the hard tip serves to reduce the acoustic emission when putting the hard tip. In addition, there is a certain protection against injury.

Reduction of the acoustic emission may also be achieved by a soft coating over the tip base 31. This coating may be formed by a rubber sleeve 115 on the pedestal 33, as shown in FIG.
