In Fig. 1 a length-adjustable ski and hiking stick is shown in the folded state. The tube 26 plunges into the telescopic tube 25 , which is connected to the handle 10 and has the task of being able to realize an additional length change of the unfolded ski pole. In this way, the individually desired length of use can be set. The functions of the clamping element 20 is described in more detail in FIGS . 13-15. The maximum immersion depth is reached when the clamping element 20 moves against the stop of the handle 10 . The ski pole is extended in such a way that the telescopic tube 25 is held at a sufficient height from the floor in the vertical direction via the handle 10 . Inevitably, due to the weight of the folding elements 27 and 15 , unfolding takes place in the vertical direction. Due to the appropriately pre-tensioned tie rod 9 , the individual folding elements are then automatically guided into one another via the guide pieces 46 and 47 up to the thread stop and braced slightly against one another. Then only by holding the tube 26 and twisting the tube 15, the connecting elements screwed together a few turns until they stop at the conical surfaces. This is followed by the axial displacement of the snow plate 19 against the upper stop in the operating position and the stick is ready for use (for more information on the snow plate see FIG. 4).

The embodiments according to FIGS. 8 to 12 can also be used as further connection units.

The folded stick shown in FIG. 1 is then inserted in practice in a bundled form into the carrying bag shown in FIGS . 6 and 7.

If an extremely strong and elastic tie rod 9 with sufficiently large holding forces is used, screwing can be dispensed with. These conditions are met using a connection unit according to FIGS. 8 and 9.

Another possibility of axial bracing is possible in an embodiment according to FIG. 1 '. Here the axial bracing is carried out by a non-elastic tie rod 9 '. Designs according to FIGS. 8 and 9 are also used as connecting elements. The telescoping also takes place here via the tube 50 and the tube 45 fastened in the handle 10 Locking the stick length required in the specific case is achieved by the possibility shown in FIG. 18. With the help of a nut 43 and an applied threaded ring 51, an elastic braking element with a high coefficient of friction is clamped so that the set length of the ski pole is locked in place by frictional forces. Further relevant design options are described in FIGS. 16, 17 and 19 to 21. To ensure a play-free guidance of the tube 45 in the tube 50 , a guide element 40 is provided. This also has the task of ensuring an axial limit at the stop against the ring 52 in the Höhenein position. Unfolding the stick takes place in the opposite way to that described in Fig. 1, namely in that the shaft 72 is held in the vertical direction and thereby the individual folding elements automatically slide into the connecting units by their own weight. Then, by holding the tube 74 and pulling on the shaft 72, the path S is canceled and the thread 73 is screwed into the internal thread de of the guide sleeve 70 until there is sufficient axial tension on the tie rod 9 '. The path S can also be bridged automatically, without manual influence, by installing a suitable resilient element between the contact surfaces 85 and 86 . The required torque is passed on to the screw connection via the rotary aid 71 . The paths 51 and 52 are coordinated with one another in such a way that changes in length due to material fatigue or temperature differences on the tie rod 9 'can be compensated for via the thread. The snow plate can then be brought into use. The four specific properties of such a ski or hiking stick required for practical use are:

• - lightweight construction
• - for all body sizes and applications adjustable insert length
• - a pack size below the hip width
• - extremely cheap handling

These requirements are met by the design variants according to FIGS. 1 and 1 'of the half, because a tube with a small diameter can be used over almost the entire length of the floor and because the joining lengths of the connecting units 21 are compared to telescopic solutions only once in the packed length.

The poles are adapted to the hand ergonomics of children or women by using a specific handle 10 'or 10 ''.

In the case of extremely different body sizes, the possibility of using a different number of folding elements 27 can also be used.

In Fig. 2, a folding stick is shown with extended telescopic device with coupled connection units and snow plates in the operating position. The telescopic device is brought into an intermediate position in the telescopic tube 25 and locked with the aid of the clamping element 20 . The connecting units 21 are connected to one another via the connecting elements 46 and 47 by the screw connection provided. This corresponds to a rigid connection of the folding elements to each other or the condition of use of the stick. The snow plate is also in the operating position.

In Fig. 3 is a telescopic stick in the retracted to the pack size to stand with snow plate shown in the transport position. It has the property that the insert length can be extended continuously from the minimum packing length to the maximum insert length. When used as a women's or children's stick, the hand ergonomics can also be adapted by using a handle 10 , 10 'or 10 ''. For people under a certain size, the tube 24 with the clamping element 20 , with the ring 17 and the elastic bearing 18 is omitted. The tube 24 a is inserted di rectly into the handle 10 'or 10 ''. Based on the fact that when setting the stick to pack size all clamping elements 20 to 20 d are in the relaxed state, the stick can be extended to the desired size by pulling. This state can be locked by clamping the clamping elements 20 to 20 d according to the description of FIGS . 13 to 15.

Fig. 4 shows a section through the displaceable snow plate 19 in the guide from folding stick. In the lower half of the snow plate 19 is shown in the use position, in the upper half, however, in the transport position. For assembly, the snow plate 19 is applied to the end piece 11 and then screwed into the threaded piece 49 and secured against rotation. In the lower area, several lugs are attached in relation to the circumference, which result from the fact that a larger number of slots are machined in the axial direction in the area there. In a set position, the snow plate 19 is held in the groove 13 by the inner bead of the resilient nose 16 . The transport position is reached, as shown in the upper half of the figure, by moving the snow plate towards the lower stop, the resilient nose 16 sliding over the bead 12 and, after springing back, constituting an axial securing means. In the transport position, the snow plate 19 also has the task of defusing the sharp edge of the end piece 11 . Such a sharpening has an accident prevention and gentle on the packaging and carrying devices.

Fig. 5 shows a section through the movable snow plate 19 in the implementation of telescopic ski pole. With regard to the displaceability, this corresponds to the function described in FIG. 4. Another advantage is achieved in that the tube 24 guided by the shaft 48 d can be pushed for the purpose of enlarging the Teleskopwe ges up to the stop on the snow plate collar over the end piece 11 .

Fig. 6 shows the hip belt carrier bag with space-saving folded and bundled ski poles 1 in the packaged state in section from the rear. A sol che carrier bag 2 is usually made of a backpack material known on the market. With the help of the belt 7 and the buckle 6 , as shown in FIG. 7, it is attached in an ergonomically favorable manner over the hip to the stomach of the skier. In order to avoid injury to the skier in the event of a fall, a cushion 8 , according to FIG. 7, is provided between the carrying bag 2 , the sticks 1 and the skier. The gripping aid 5 has the task of capturing the flap 4, which can generally be closed with Velcro, and can be opened easily. The closable flap 4 is shown in the closed and in the open state. The flap on the left side is opened from top to bottom, the flap on the right side is opened from bottom to top. The pocket bottom 22 leads both on the left and on the right side to the intermediate wall 3 and serves to receive the counterpart of the Velcro strip or the closure 23 of the flap 4 .

FIGS. 8-12 show connection units, which are relevant only in connection with a folding stock solution.

In Fig. 8, a connecting unit 21 a is shown, the plug 28 and the receptacle 29 is constructed on a cylindrical basis and has a relatively long overlap path. Due to the special configuration, positions 28 and 29 can be easily combined and the large overlap distance leads to a very stable connection unit. Such a solution is usually only realisable with an elastic tie rod, which has a very flat characteristic. When using a non-elastic tie rod, as shown in FIG. 1 ', the addition of the relatively long joint lengths at the individual connecting points makes it difficult to achieve.

The tubes 26 and 27 are fixedly connected to positions 28 and 29 and are components of the folding elements.

Fig. 9, on the other hand, is designed so that due to the short length of the joint, elastic and non-elastic tie rods 9 and 9 'can be used. The conical merging ensures a simple and stable centering merging.

The tubes 26 and 27 are fixedly connected to positions 30 and 31 and are components of the folding elements.

If elastic tie rods 9 are used in FIGS. 8 and 9, then the axial holding forces must be greater than the maximum operating forces acting in the pulling direction. However, holding forces can also be understood to mean those forces which result from the conicity when the plug-in and receiving elements 30 and 31 are joined together.

In Fig. 10 a connecting unit is shown which has a particularly stable transition situation, the result due to their elongated shafts. The combination of the plug element marked with position 34 with cone outside and thread inside with the receiving cone and thread inside position 35 is similarly elegantly solved as in the illustration in FIG. 9. The advantage of such a solution is that a very weakly dimensioned tie rod is used can be, which has only the task to center the positions 34 and 35 after unfolding the Stoc kes over the cone elements and has only such a slight axial force that the external and internal thread of the connecting unit 21 c has contact with each other. If this is the case, the stick only needs to be held on the handle 10 and rotated on the tube 15 so that all screw connections connect to one another and thereby inevitably generates an axial holding force via the conical connections. No additional axial forces are imposed on the tie rod 9 during use.

Fig. 11 shows a section through a connecting unit 21 d with conical plug element 32 and receiving element 33 in conjunction with external threads and pre-tensioned elastic tie rod 9 before coupling.

In Fig. 12 the elastic tie rod has already brought the elements 32 and 33 together up to the threaded contact. Here, the path s can only be bridged by twisting each other and the inner and outer cones can be clamped together.

With the help of Fig. 13 to 15, the functional relationships are of a Klem melementes will be explained in more detail 20 and 20 d. The eccentric 39 is fixedly connected to the tube 26 and has the task of guiding the documents 36 , the elastic elements 37 and the braking elements 38 with the aid of the collar 83 and 84 . These three ele ments are installed with a certain bias and glued together at their contact surfaces, and matched to each other so dimensionally that the Bremsele element 38 in a position shown in FIG. 14 constantly generates a low frictional force. This frictional force is sufficient that when the eccentric is rotated from the position shown in FIG. 14 to the position shown in FIG. 15, there is no displacement between the brake element 38 and the tube 25 . The closer the eccentric 39 approaches the position according to position 15 , the greater the contact force, ie the frictional force or the axial holding force. This position corresponds to the insert length set and locked by the user. The great advantage of using such a clamping element is the short design associated with it and the extremely short twisting angle when tensioning. The short design has a particularly advantageous effect in a telescopic pier device according to FIG. 3. An elastic guide ring 18 has the task of eliminating the play between the tubes 25 and 26 and avoiding rattling noises. The ring 17 has the task with the help of its larger outside diameter and a rough surface to enlarge the torque which can be generated by hand.

Fig. 16 shows a section through a telescopic device strained clamping device 78 and a conical ring 44. In this case, by turning a nut ter 43 which also has an oblique contact surface with respect to the conical ring 44 , an axial force is generated which is supported on the tube 41 and the threaded ring 42 . Due to the flat angle of the nut 43 and the brake element 44 , the axial force introduced is converted into a substantially higher radial force. It is important that the coefficient of friction between the nut 43 and the brake element 44 is small and the coefficient of friction between the brake element 44 and the tube 45 is large. This leads to a relatively high holding force being generated between the brake element 44 and the tube 45 with a relatively low torque on the nut.

This effect can be improved in that the nut 43 according to FIG. 17 has grooves with a good grip or a rough surface, which enables a non-slip power transmission between the hand and the nut. Here, too, the play between the tubes 41 and 45, a guide member 40 may for eliminating such in shape. B. a high-strength adhesive tape can be used.

Fig. 18 shows a section through a telescopic locking device with clamped clamping device which corresponds essentially to Fig. 16, but on the Bremsele element 52 and on the threaded ring applied a further inclined ramp surface be. Since large force peaks and thus large displacement forces in the direction of the arrow occur in practice when using the pole, an additional contact force is generated between the tube 45 and the brake element 52 at this moment by such a surface. This avoids unwanted shifting movements.

In an embodiment according to FIG. 19, the conical threaded ring which is attached and is fixedly connected to the tube 41 is provided together with slots 77 , so that when the nut 54 is screwed on, a deformation toward the tube 45 is possible. This creates an axial holding force.

The variant according to FIG. 20 is constructed in such a way that the telescopic locking is created in that a correspondingly shaped nut 59 is equipped with an elastic ring 61 . When tightening the nut, the elastic ring 61 is strongly compressed and generates correspondingly high contact forces between nut 59 and tube 45 , which generate a correspondingly high holding force.

Another embodiment of a clamping device is shown in FIG. 21. Since the inner tube 60 is provided with a groove. A resilient ring 57 is received in a nut 58 . This nut 58 is screwed onto a threaded ring which is applied to the tube 41 . By further screwing the ring 57 is pressed against the oblique contact surface of the nut 58 , deformed inward and produces a locking effect through the groove of the tube 60 .

Under Fig. 22 is a connection unit 90 with an elastic sleeve 87 Darge is applied to the side of the tube 88 with a shrink seat 91. On the side of the tube 89, on the other hand, a press fit 92 is provided which is characterized in that the tube 89 has a larger outside diameter in the region of the press fit than the sleeve 87 . The tube 89 initially has a cone so that an easy insertion into the elastic sleeve 87 is possible. Due to the press fit in the area 92 , there is a play-free connection between the tube 88 and tube 89 and axial holding forces which have a relieving effect on the tie rods 9 and 9 '. The tube 89 can be provided with a short cone 93 or a long cone 94 . Since the manually exertable axial forces for inserting the tube 89 into the sleeve 87 are limited, it is possible due to different conicity in accordance with embodiment 93 or 94 to generate the desired spreading forces on the press fit 92 .
