The invention aims to create r .-: i.nc .- = in its entirety effective protection against injuries -safety ski tockes.

Although skis-scoke of the usual type in their basic conception and in their stated structure constituted a considerable source of danger for the skier, responsible for many injuries and physical injuries of other kinds, so far only suggestions and attempts have been made ± vi Iliücliek for a failure-reducing correction Individual elements of the ski pole there. However, these corrections resulted in ao?:. -Provider.

His conception for the creation of a safety ski pole in its entirety as a safety ski pole lind in its Gesanithsic vvirl ·: ser :; Skistocks, which protect against injuries, however, have so far been completely ferj.te.

Trying diaie-.G-efaJirGii ^by: the use of elastic Ski - / ^ A stöckrohre to capture, resulted in no solution to the problem, because "at a low elasticity of the pipes there was still a high risk of injury during a high elasticity of the pipes led to a noticeable uncertainty in use and thus to a new risk to the skier was equipped with a special elasticity in the direction of the shorter axis of the oval. If the skier fell on the ski pole from exactly above or in the direction of the longer cross-sectional axis, there is still a risk of injury, while the flexibility of the ski pole in the direction of the shorter one Cross-sectional axis led to an uncertainty in use. Had such an oval tube a Since there is only a low degree of elasticity in the outer direction of the shorter cross-sectional axis, the risk of injury could not be significantly reduced in any direction from the outset.

In cases in which the material of the ski poles is elastic, but was not very resistant to breakage and was subject to the skier's impact Also could not be kinked or permanently bent, came 63 also to the dangerous skiotock breaks.

Even the previously common ski pole grips could not match the human Body offer little protection if it falls at high speed on the relatively small and hard surface at the upper end of these handles .. The pressure that acted on a small area of the human body in this situation, could reach a very extraordinary height. A \ me through a Thickening the top of these handles could not substantially alleviate the destructive force and severity of a heavy impact will. Even the installation of a coil spring in the handle could not eliminate these dangers, as the ski pole fell behind compressing the spring again with hardness against the body of the ski instructor. At the same time this I »'a3-naiu.ie also acted as intermediary oin feeling of insecurity, since the hard riff also with the norx-.alüii use of the ski stool; yielded and bounced back. These Uncertainty in the use could also be caused by the introduction a locking device for the temporary fixation of the position

of the handle ".: -.! ok u b'e-seixig-υ, since it is impossible to lock the / yW handle before each individual pressure or shock load on the ski pole. Apart from that, the built-in coil spring would puncture and thus lose their protective effect, albeit a limited one, if the handle is locked almost constantly during normal use. are also generally limited.

Also the popular suggestions for an injury-reducing ski pole tip, e.g. a blunt, spherical tip made of plastic The form of the tip that is encased or made up of several small partial tips do not significantly mitigate the dangers can arise when the skier gets out of control advised ·. Fell or because of the fall of another skier, hit the tip of a ski pole pointing upwards. In these cases, too, the pressure of the impact on the tip of the ski pole is only distributed to a very low level Area of the human body. On the other hand, the stump also exists in good health; such a point natural Gi'enzen, there the tip on a firm and smooth snow surface as well Ice should provide a secure hold. These limits for a safety-enhancing Training of the lower end of the ski pole resulted from the fact that with the prevailing technique of skiing on this Place only one centrally arranged ski pole tip that is sufficiently far away from the snow basket is possible.

Another significant source of danger for the skier is that the skier gets caught on an obstacle while driving with the ski pole and the skier's hand is simultaneously held by the loop of the ski pole. In many cases, the loop does not come loose from the wrist if the ski pole leans forward in the direction of travel under the tensile stress that occurs. In these cases there was often an excessive tension on the Arnes, resulting in an excess of the H &: id- and Schultercelunkes, but also particularly sudden and violent ones. Fall, which often led to further injuries.
The ski pole could easily reach obstacles, e.g. in

a bush, '^ .iLn ^ enbl ei «, if the sciineeteller has a gc-sch its outer ring b ^ sat. Some reduction in this risk resulted, even if the strength of the snow plate εΛ-decreased, through the use of snow elephants, which do not have a closed outer ring.

However, the SkistocK could also be used with these Scr are usually star-shaped and still hang on obstacles stay, e.g. on fork branches or between fence slats, rubble and ice. This danger also existed with snow plates that were after down. are bell-shaped and made of a solid material exist; it could only then with a certain reliability kbit be overcome when such downwardly open snow plates are made of a very elastic material. Such bell-shaped and at the same time elastic plate were, however, practically not used at all, since they are used in the Use were very unstable and the S> ifah_rer, especially when sloping Piece addition, did not always offer a secure hold in the snow, it does, however, when the bell is raised differently also not made possible by the use of sticks, tich at the same other conditions to repel v / and on the ground with the same force.

So far, however, the proposals have also been able to satisfy that it is enough had set themselves the goal of getting caught with the ski pole to take away the danger by using detachable or separable handles or loops.

In the proposed models in which the handle is pulled by an excessive pull from the ski pole via the loop solved, were at least the stability of the ski pole at the transition point from the handle to the upper pole or the Option to reattach the handle to the slope unsatisfactory. A simple reattachment on the slope was not possible with the constructions either, in the case of public veins The upper part of the handle could be detached from the ski pole together with the loop in the event of overuse. Depending on the species the execution of the detachable handle, however, were with these constructions mostly connected to other parts of the Kach.

In the proposals and attempts that have become known for a loop that detaches itself from the handle in the event of excessive stress , it was disadvantageous to use the loop as in the conventional ski

Lock handles in their upper part in the handle approximately horizontally anoxdnet v / ar. In these cases, the detachment of the loop from the rt.uid grip, especially darji, was difficult or endangered if the S>: .- 9 Lock when getting stuck on an obstacle in the direction of travel leaned forward, because the loop on hers became too The exit point from the handle is bent in the direction of travel, So that at this point a KrILf tezerleir-uig occurred, accompanied by considerable frictional losses, which had the effect of affecting the Anchoring the loop in the handle could only relieve some of the tensile forces that actually occurred on the outer part of the loop occurred.

The release of the human handbone was of a similar nature Getting caught with the ski pole in the event of danger if unsafe this should be guaranteed by a push button, as it should be. This push button is familiar to textile processing was in the upper part of the loop as a connecting element between the two sections of a two-part:.! Loop attached. If a more tightly closing push button was used in such a case, the locking effect of the push button prevented the essentially at right angles to the tensile force that occurred, in all cases a release of the human hand on the back side from the loop through the loop. However, it became a push button If used with a lower locking force, this push button could often be used even during normal use of the ski pole open and in this way create a real insecurity. The attempts made in this direction were therefore perceived as unsatisfactory temporary arrangements.

It '.Airde also made the proposal to open one prematurely such a push button between the outwardly bent ends that of both. Schiauf enteile was attached by using an inner connector for the two at the same time Loop parts to prevent one of the two loop parts firmly and with the other loop part through a loop put loop is releasably connected.

Even the proposals made decades ago, which only enabled the loop to be detached from the handle if the ski pole got stuck, do not yet provide a suitable, fully developed solution, so they can be found despite the great need for security in this area, which is also found in the various different types Suggestions and attempts from the interim period, could not be implemented in practice. The proposal of attaching the loop to an elastic, uir. The ski pole lying around and the ring that could be pulled off at the top was practically only possible within the framework of the usual method of attaching a loop to ski poles made of wood or bamboo cane without a separate handle. Finally, the proposal to suspend the loop with the help of a fastening ring attached to its upper end between the ski pole and a narrow pedestal that could be opened at the top still had various shortcomings which prevented this method of fastening the loop came into effect in practice. Above all, this method suffered from the lack of stability of the spring element against frequent heavy loads caused by the pulling of the loop during normal use. AuSerde;.: V / is practically not possible with the existing ski poles a wider design of the spring element without a simultaneous curvature, which would have made an upward movement of the loop considerably more difficult. In addition, the spring element could also be bent to the side during normal use of the ski pole in the event of heavy use. In an alternative embodiment, in which this retaining element is not resilient, but an elastic rubber bead is attached to the deniokistock above this retaining ring, it is difficult to set a high threshold value for the Adjusting the detachability of the loop Another reason for both designs consisted in the fact that it was difficult to mount the loop on the ski pole again using the fastening ring attached to it, if the eighth bracket part attached to the ski pole was used to create one high sciiv-eliv / erts for the loosening of the loop very close to the ski pole and had to be made of a very solid material or the corresponding rubber bead had to be made of alneh for the same reason . selir fixed :: a-: erial existed.

Object of the present invention is ^J o to create a ski pole, which is created in its entirety and in its individual parts on an effective hedging of the skier from injuries out.

According to the invention this is achieved in that the Ski pole is constructed in its entirety from several parts, which take place in one in the longitudinal direction of the ski pole Collision of the skier with the uppermost part of the ski pole are movable against each other at least at one point in the direction of the occurring stress.

Such a ski pole is movable in particular from at least two interconnected pipes constructed and further characterized in that locking members for inside the pipes Establishing a firm connection of the pipes during use des 3kistocir.es are present and that these locking organs from the handle her uo far displaceable from its locking position are that the pipes under pressure and stoi'i on the ends of the ski pole are mutually movable.

Furthermore, features of the ski pole according to the invention are that the upper end of the ski pole is designed as an elastic buffer i3t uiid dai .. the tip of the ski toc: it is movable at the bottom connected pipes attached and together with this The pipe can be moved up to the snow plate; also is the Loop on the handle due to tensile stress in that direction the upper end of the ski pole releasably mounted.

The Verriegeiungsorcans present in the ski pole can be used to automatic adoption of the locking position of each element related to tension in the direction of the latch.gss division are equipped. They usually own also one arranged at the upper end of the handle, by pressure and push downwardly displaceable in the longitudinal direction of the ski pole upper end piece and are with the help of an Acwärxsbewegung this end piece can be moved out of its locking pitch.

'In particular Outwardly movable support parts can be provided in a position on the outside of the handle in which they are when Resting the hand on the upper end of the handle are exposed to inward finger pressure.

The tubes of the inventive ski hook can be telescopic as well as articulated.

Furthermore, devices that can be operated from the outside can be installed in the ski pole to hold the locking members in the locked position, even when the ends of the ski pole are pressed and hit be.

Lierkmale concerning the shaft, grip and tip of the ski pole of the invention, since they are in themselves already an inventive character own, be protected with the desired overall protection in each case.

With the help of the invention, the following effects and advantages in particular can be achieved: Owing to the locking devices that are present within the ski pole tubes and are automatically held in their locked position with the help of built-in pedals, the ski pole according to the invention is completely pressure-resistant when used as intended But if the skier falls in the direction of the longitudinal axis of the ski pole on one of the two ends of this ski pole, this impact has a direct effect on the upper end of the handle, ie above the upper handle which is used for clamping by the hand End piece of the locking organs. By simultaneously triggered, against spring pressure \ uia possibly taking place against the resistance unxergesetzter support members downward movement of the upper end portions of the locking members, the other parts of the locking elements are out of their Verrieselun _t, c; sxellung shifted.

Prevention of falling of the siifanrer usually from the beginning a, ~ e- / - / - know , with the telescopic shortening of the ski pole, there is a further increasing Y / inceldifference and that at the upper end of the ski pole is an elastic Pu.:ftr .urhahden whose elastic Giving up sliding away er.V; xchtert. By this reaction of the ski pole becomes the danger for the skier through the ski pole punctured or otherwise injured or damaged in any significant way, eliminated immediately. The one at the top Enae of the ski pole attached elastic buffer, which at the same time forms the upper part of the upper end piece of the locking mechanism, dampens the effect of every impact on the from the start Upper ski pole.ide and especially protects the easily injured Body parts on the neck and head of the skier. It also causes it is already effective in lighter falls that do not yet cause the skisxock tubes to slide into one another Protection. However, this buffer also prevents the very rare exceptional cases in which the Sicistock may tilt or slide once it is not possible; ·; should and the dangerousness of the push by the yielding of the stick is not fundamentally either decreases because z.3. the skier over the shorter ski pole mixer at the same time dragging this stick to the ground more easily fall, serious injury due to its cushioning effect.

Skis to eier obre ax the tendency to tip sideways or slide away, movable back under your skier's body. Of the Skiers can use the particularly advantageous telescopic Connection of the carrier tube with the other adjoining it Lastly, the ski hook tube only catches your eye on the snow basket, which is relatively harmless.

In some cases, the loop provided, which can be released from its support by tensile stress in the direction of the upper end of the ski pole, makes it easier for the ski pole to slide sideways under the body of the falling skier. By allowing the loop during the lateral ^ Ye / -gleit ens of the ski pole in the direction of the upper Skistockendes of the handle solve, is _f preventing the ski pole firmly held on the body and can be for the skier to the danger se. At the same time, this loop also prevents the skier from being endangered if the ski pole gets caught on an obstacle. In these situations, the loop pivoted in the direction of the upper end of the ski pole, if it is suddenly exposed from the inside to a stronger pressure of the wrist acting in the same direction, in each case represents the uppermost part of the ski pole. A very advantageous, so far not yet proposed shape for the required detachable loop, which avoids the drawbacks of the previous specific solution attempts and thus for the first time meets the requirements of practice, is shown in the following in the context of the exemplary embodiments.

After all, this ski pole can be used for. Purpose of a lighter, space-saving Transports by hitting the top end dos Handle can also be deliberately shortened. In this way, the tip is also stored so that it can be pushed back and defused as a source of danger.

A buffer designed in this way is able to distribute the pressure of an impact against the body over as large an area as possible and to absorb it as softly as possible. In the event of a fall on the upper end of the ski pole, it also significantly dampens the destructive force of the ski pole. In particular, in the event of a fall, this buffer, in cooperation with the telescopic retreat of the ski pole, prevents injury to the skier at the particularly endangered areas of the human body, for example the exposed areas of the neck and head. The injury-reducing effect is also particularly effective in cases in which the fall is not a particularly serious and dangerous one, i.e. in which the ski pole tubes are not yet pushed into one another. Basically, this buffer '■■■' ■ always leads to a reduction in the risk of injury because it yields elastically on impact with the human body and thus makes it easier for the stick to tilt or slide away.

With the handle shown, it is possible for the skier to close the lower holding part 34 in the usual manner with certainty clasp that the ski pole tubes during normal use are completely pressure and shock resistant. Only ground in the event of a fall or impact on the upper end of the ski pole the locking elements provided inside the ski pole so ■ · Moved far from their locking position that the ski pole tubes can slide into each other under the pressure acting on them. V

With the present ski pole, however, the skier is also able to " borrowed to sit securely on the ski pole from the top of the handle to support without interlocking the ski pole: having to reckon with pipes. Figure 3a shows that the upper end piece of the locking members for this purpose not only by the helical spring 8, but also supported by solid and at the same time elastic support parts against the lower part 34 of the handle is. Support parts of this type can be attached both to the cold part 34 and to the upper end piece 6 of the locking members be.

In the embodiment shown, they form part of the upper end piece 6 of the locking organs and consist of downward directed extensions 49 of the elastic buffer 3 and off

The inwardly pointing spring eyes 51 are formed at the lower end of this spring length po. as the distant pieces between the fixed lower part 7 of the upper end piece 6 laici. i,: are clamped in the lower holding part 34. These spring eyes 51 ″ have an outwardly rising shape on the upper side and a shape that slopes downward on the underside and their lower side rests on surfaces of the lower cold part 34 which are sloping towards the outside (Shown harmless distance because of Fig. 7a-7ö) By means of these support parts 49 »5 °» 51 it is achieved that the upper

sufficient
End piece 6 also remains in its other position when the skier is supported on this end piece from above, for example when climbing on skis. On the other hand, it is also ensured that the support parts 49, bo, 51 can be pressed outwards in the event of a fall of the skier on one of the two ends of the ski pole due to their elasticity and due to the oblique plane part described, in order to unlock the upper end piece 6 of the locking elements of the pipe connections to clear the necessary path downwards. A shock against the body, which can no longer be sufficiently damped by the buffer alone, can thus also be relieved of danger in this case by creating a movable connection between the ski pole tubes.

The skier can, however, while he is from above on the ski pole supports, push the ski pole against the ground without the ski pole sliding into one another. The shape shown of the buffer 3 causes the skier, when executing this shock, to put his fingers against the support parts 49, 50, 51 from the side in the top.

Even if the buffer were omitted, the described effect could e.g. Achieve by a cap-like design of the fixed lower part of the upper end piece of the locking members with equilateral attachment of laterally resilient support parts.

Furthermore, it is possible, through suitable shaping, to create a direct Transition between the upper end of the locking members and the lower. Ensure holding part of the handle and covered instead of the open air grooves 43 provided there horizontal guides to be provided for the movement of the upper end piece.

Figure 4 shows the middle area of the ski pole according to Figure 1, in which the two ski pole tubes 1 and 2 are connected to each other, in enlargement.

The Lianschette 16, which is firmly attached to the upper further tube 1 and narrower on the lower. Tube 2 is easy to slide on, is, with the same function a: a fully assembled ski pole, but deviating from Fig. 1 - only made of one piece.

At the same time, it is guaranteed that the ski pole tubes ^! cannot be moved apart beyond the position shown.

Pig 4 also shows that part of the inner locking organs of the ski pole which, together with the part of the locking organs located in the area of the handle, ensures that the ski pole tubes cannot be pushed into one another by the loads that occur according to the design. This part of the locking members, which consists mainly of the annular Zv / ischeiis tück 1o, prevents in its horizontal position that the leaf spring 12 used to connect the tubes 1 and 2, the lower ends of which are bent towards the outside to spring eyes 11, to the normal use of the ski pole can be moved out of position.

The leaf spring 12 is mounted in the interior of the lower tube 2 and fastened in this with the aid of the mounting piece 13, which by lateral openings of this tube inserted through and with a horizontal Sciilitz for receiving the leaf spring 12 is equipped. Leaf spring 12 and retaining piece 13 v / iron vertical openings, through which the control rod 9 leading to the handle slides well The at the lower end of the leaf spring 12 formed spring eyes 11 protrude below the tube 1 through Openings 55 of the tube 2 to the outside and form on its top a sloping one that rises towards the inside of the ski look Level. The space between du ::, lower end of tube 1 and the cross bar 11 is filled by the cuff 16.

can be designed in such a way that they withstand all loads occurring "* αί" without deformation; however, it is also possible to insert solid inserts made of metal, for example, into these spring eyes for reinforcement. Instead of forming spring eyes 12 on the leaf springs, it is _{but it is also possible to attach functionally shaped,} outwardly protruding locking pieces, e.g. made of steel, to the lower end of a U-shaped bent leaf spring prevent sliding down over the tube 2, hereinafter referred to collectively as Querrl5gel.

To the retreat of the cross bar 11 in the pipe 2 and danit the sliding of the ski pole tubes into one another during normal use Without being able to safely avoid additional measures, the annular intermediate piece (the locking ring) Io in its main part is cylindrical and the adjacent surface of the crossbar 11 is perpendicular. In this way, the Cross bar in Ί on the intermediate piece 1o no power transmission take place in the longitudinal direction of the ski pole, a longitudinal advancement of the intermediate piece 1o and thus also an evasion the cross bar 11 could allow inside the pipe.

In the event of a fall on the ski pole, however, a rejection To enable the cross bar 11 in the tube 2 and thus the ski pole tubes to slide into one another is the following basic principle Arrangement made: The intermediate piece 1o is attached to the control rod 9 below a stop 54 provided on it and is therefore with a downward movement of the control rod 9, which in the event of an impact on the two ends of the ski pole by the downward movement of the upper end piece 6 of the locking members is triggered, pushed down out of the area of the crossbar, so that the crossbar 11 is below the effective Pressure in the pipe 2 can recede.

In the present embodiment, the further essential advantage is also realized that the Skistouk tubes as a result of a special design and storage of the intermediate piece 1o slightly in the event of an impact on the ski pole, but only in the event of a static pressure load on the upper end of the ski pole be pushed into one another in the event of a st.ir high load can. This advantage is made possible by the fact that the intermediate

piece Ιο, as shown in Fig 4, in its above the transverse

"ΐ Ft" h bolt 11 located upper part slightly conical shaped ^v and; üa2 <on the control rod 9 displaceable, between the upper stop 54 'and a helical spring 14' placed below the control rod, which in turn is mounted on the underside of a stop 17 on the control rod 9 is supported. In this special design, after the described downward movement of the cylindrical part of the intermediate piece 1o, the upper conical continuation of this intermediate piece is still located between the crossbars 11; Due to the inward pressure of the crossbars, the intermediate piece 1o is then pushed so far downward out of the area of the crossbars 11 against the pressure of the spring 14 that they can retreat completely into the interior of the tube 2. This process takes place if only the effect of the device shown in this figure, but not that of the unlocking ( only at such high exposure values that for this reason the skier can lean on the ski pole with all his strength from the upper end without having to expect it to collapse small impact acting on them possible to push the conical part of the intermediate piece 10 completely out of their space.

The movement of the crossbars 11 is not hindered by the pipe wall adjoining below, because the openings 55 in the pipe 2 are kept so large that they give the crossbars 11 so much leeway that they cannot touch the adjoining pipe wall. The opposing pressure of the two tubes 1 and 2 has an effect on the interface between the iianschette 16 and the upper surface of the crossbar 11. These crossbars 11, together with the springs Yd which are subjected to tensile stress, form part of the tube 2.

To use this To enable spring 19, a spring naturally used in the handle v / earth that is so strong that it counteracts the Pressure of the spring 19 i * i overcomes the required extent.

Instead of the embodiment shown in FIG. 4, it is also possible to firmly connect the intermediate piece to the control unit and at the same time instead of the underlying spring 14 a corresponding one To arrange spring element in the area of the handle, against which Resistance pushed the conical part of the intermediate piece 1o down must become. This effect can "with a correspondingly prolonged Spring ö can be achieved.

If you don't care, the threshold value for the static load capacity the ski pieces when supported 0:11 upper end of the handle twice, through the design of the handle and because of the type and storage of the intermediate piece 1o, too secure, so nan can either go to the studi: parts 49, 50, 51 or completely or partially do without a steep cone in the upper part of the intermediate piece 1o.

In addition, the rope 21 is shown in Fig. 4, the lower End piece 17 of the control rod 9 is attached and for storage the tip of the ski pole leads. The disc 18a attached to the end piece 17 just above the rope prevents the wire rope from moving 21, which when the ski pole tubes slide into one another .1 and loosens, between the locking and above Spring organs can get caught.

the lower holding part 34 result. · ..'... · ^:. '. :: * 5 / Together with the illustration of the detachable loop 4 v / the details shown in FIGS. 6 a to 6 c are described. The loop is fastened to the holding part 34 with the aid of a fixed cross-piece 37, for example made of metal, provided at its upper end. To support this cross piece 37, upwardly curved port positions 35 of these handle pieces serve as outer holding parts and a leaf spring 36, which is also attached to the handle piece and which is printed from the inside against the cross piece 37, serves as an inner holding piece. An example of a way of securing the leaf spring 36 in the holding part 34 can be seen from FIGS. 2 and 3a. The cantilevered port translations 35 of the holding member 34 and the leaf spring 36 enclose from the side wholly or partly the upper part of the crosspiece 37 * The cross-piece 37 can therefore only be released from its holder, when the S _c hlaufe 39 of the upper Skistockendes in the direction is subjected to tensile stress # For this purpose, it can also be useful, viexw. the outer and the inner holding part of the cross piece 37t v / ie shown in Pig 5, in the section pointing towards the rear of the handle end.

The training of two or more, in one as large as possible Port settings 35 (Pig 6 a) arranged at a distance from one another are made possible a downward course of the loop between these continuations during normal use of the loop. In the present example, there are special band-like connecting parts 38 between the crosspiece 37 and the main part 39 of the Loops are provided, which lead through between the port settings 35. These band-like connecting parts 38 are, as from the Figures 6b and 6c can be seen, at its upper end around the crosspiece 37, widened in its lowest part and connected to the main part 39 of the loop, which consists e.g. of leather, by the rivets 4o. Are just two sequels present, and is the main part 39 of the loop in its upper part kept narrow, the main part 39 can not only by a single band-like connecting part, but also directly seibsx be veruur.üen with the crosspiece 37.

Since the tabs 35 have great strength, they enable the loop A in normal use in which the loop is directed downwards or horizontally to the rear

can be subjected to strong pulls, a completely firm hold in their storage. To the continuations 35 in the direction of this normal To make stress particularly resilient, these can be made entirely or partially of metal. Furthermore are these continuations 35 and the associated spring element 36 ε.η their The inside is as circular as possible in order to ensure good rotatability of the crosspiece 37 in its holder. These continuations 35 also prevent the loop 4 from sliding out of its holder on the handle. To also to prevent an upwardly directed loop 4 from sliding sideways out of its storage when the spring element with its upper end does not lie completely close to the continuations, the parts lying between the continuations 35 can of the cross piece 37, as can be seen from Fig. 6b, be made reinforced. This reinforcement can also be done by laying it around. of the connecting parts 38 around the crosspiece 37 can be achieved. · .-.

A stronger pressure on the spring element 36 directed against the handle is always possible a simple reattachment of the loosened loop by reinserting the crosspiece 37 from the side or from above here.

The type of detachable loop described avoids the disadvantages associated with previous attempts and proposals in this field and makes it easier for the shortened ski pole to slide away under the skier's body. Due to the way it is mounted, the loop can be subjected to the greatest stress during normal use, but cannot be loosened, while the loop can be loosened in the required direction if it gets stuck. The stability of the storage enables a heavy load even in the long term. For the loosenability of the loop by tensile stress in the intended direction, a threshold value tailored to the health requirements was set; this threshold value can be regulated precisely and permanently, in particular by the shape and the upper distance of the holding parts 35 and 36 as well as by the strength of the crosspiece 37 and the spring 36. Finally, it is also important that this solution is immediate for the skier offers a plausible and convincing realization of a detachable loop, which prompts him to actually use it for his own safety. - -, ~. ^ _r , ~

In the figures 7a "to 7c a particularly te embodiment of the upper part of the handle is shown, which enables the skier to hold the locking elements built into the ski pole in their locking ie: 2.-uζ , ie to As a result, the skier _, if there is a need or desire in this direction, has a ski pole at his disposal, the tubes of which remain rigidly connected even if the upper end of the ski pole is hit.

TJn to produce such a lock, it is only necessary in this embodiment, dao upper end piece 6 of the locking orgcine from its Komalü division out transversely, so that the noi-ua-1weise longitudinal buffer 3 is transverse to the direction of travel. A zvsi Zv; corner of the locking of transversely positioned buffers 3 is shown in Fig. 7d. When climbing on skis, nan can also support himself well from above on such a transverse buffer. Au;: · earth:.: The skier recognizes by the position of the buffer 3 at any moment whether the ski pole is "locked" or is due to be used as a safety pole ...

This transverse positioning of the upper end piece 6 of the locking mechanism is appropriate, since in the annular continuation 42 of the lower holding part 34 not only the already mentioned guide grooves 43 (Pig 2), but also your guide grooves running to these are provided. These cooling grooves 53 branch off from the vertical grooves 43 just below their upper end. These transversely extending grooves prevent the guide pins 44 guided therein (FIG. 2) and also the remaining part of the locking mechanism from moving backwards. In this way, the locking organs cannot be removed from their 3-digit locking mechanism. !

Guide grooves 56 and 57 serve only for the introduction of the guide posts 44 (Pig 2) and enable a decrease through a conscious application of pressure from above while rotating at the same time of the upper end piece 6 of the locking organs from the rest Part of the handle. You in Fig 7 a offered brewing looks at the remaining lower part of the handle shows that the described guide grooves for guiding the two pins 44 (Fig 2), opposite to each other, each present twice. 7c illustrates this in a development of the outer surface of the annular Continuation 42, this processing beginning and ending at point A marked in FIG. 7 a.

To lock and unlock the Rohrvcrriegelung it is only necessary to turn the buffer 3 and with it the upper end piece 6 old a downward pressure of the hand un each time. Because the respective end position of the guide pins 44 is higher than the transverse groove 53 under the upward pressure of the spring S (FIGS. 1 to 3 a), unintentional locking or unlocking of the locking elements can be excluded from the outset. However, in order to enable the buffer 3 to be turned deliberately, the transition to the transverse groove 53 located below is rounded. While the guide pins 44 are located in the transverse grooves 58, only the cylindrical lower part of the intermediate piece 1o still rests on the inside of the transverse bar 11 (FIG. 4), so that the transverse bar 11 does not move under pressure

ini.en can move (higher grooves 58 and thus deeply lying spring claws 5b, Fig. 3a, possible). The use of similarly running guide slots instead of these guide grooves is practically only possible if the helical spring 8 is housed at a point slightly higher or deeper in the ski pole, namely between a lower fixed stop, which uit the holding part 34 or with the ski pole is in Verbiuäunj, and a slightly higher arranged stop on the control star-gü 9. The grooves 56 and 57 can be dispensed with, v.erui the FLUirun ^ öctifte 44 in the upper end piece 6 of the Verriejelung3or £, aue from the outside are insertable.

At the same time, this course of the guide grille 57 cannot prevent the necessary throwing motion of the guide pin 44 in the event of a fall.

The specified embodiment is intended to clarify that 'es sur "^? <~, Creation of such a locking device in principle only matters. that in the connecting organs of the lower Holding part of the handle and the upper end piece of the locking members arranged above it are guide cams which are constructed according to the principles given and regulate the mutual mobility of these two parts of the handle «

With a ski pole, in which the locking elements in the described Are held in their locked position, the skier can also, e.g. while climbing on his skis then hit the ground hard when he lifts the ski pole from the upper end of the handle only holds it very loosely.

In FIGS. 8a to 8d, a further possibility for locking the pipe lock is shown. In this The case is locked by a built-in rotary slide 60 in the handle, which with the help of a lever 61 from the outside can be operated from here and by turning 90 ° in relation to a special profile piece of the control rod 9 can be placed across can, so that a downward movement of the control rod becomes impossible. On the basis of this basic principle s: .nd also other embodiments, E.g. a lateral positioning or locking with the profile of the control rod is possible even with a slight twist.

In the sectional illustration of the handle shown in FIG. 8 a, the following change has been made compared to the illustration in FIG. 2:

In the interior of the annular upper continuation 42, the rotary slide 60 rests under the compression spring 8 on the holding part 34. In this rotary valve there is a rectangular opening 62 through which the round main part of the control rod 9 is passed. Above this opening 62, the control rod also has a rectangular cross section in the short section 55. This is, however, kept somewhat smaller al3 at the opening 62 and can therefore, with the same direction of the rectangles, be taken up by the opening in the rotary slide valve Co. : ~ en - ..

The first-mentioned situation of rectified rectangles is shown in Pig 8 c, the second-mentioned situation each other querges part pike corner in Fig 3 d. Both figures show a cross-section (arch of the handle just above the rotary slide 6o with a view of the rotary slide below it. In these figures it can also be seen that at the height of the rotary slide 6o in the annular continuation 42 a recess 63 is provided which a quarter turn of the operating lever 61. On the underside of this recess 63, the recessed locking part 64 and the locking point 66 for the locking position are provided for the horizontal position of the operating lever 61. To move the rotary slide 6o, the operating lever 61 and then also the rotary slide 6o etc. are provided ; as is raised against the pressure of the above-connected helical spring 8. Due to the recessed latching points 64 and 66 and the need to raise the operating lever 61 against the pressure of the spring 8, the rotary slide 6o is secured against unintentional rotation color coding of the part dos Rotary slide 6o, which is visible in the recess 63, an additional control is possible as to whether the ski pole is "locked" or not.

The round basic shape of the recess at the lower end of the ski pole tip makes it possible In addition, a possible accumulation of snow or ice can be more easily twisted out of this recess by the pressure of the stick insert. The type of point support shown in the figure is, however, fundamentally independent of the form of the lowest point applicable? this was chosen for the sake of optimal protection.

The fixed connection of the push-in tube 27 to the tube 2 takes place in a similar way to the connection of the two tubes 1 and 2 already described Spring eyes 24 formed at the lower ends, which serve as crossbars, as well as the annular intermediate piece 22, which is pushed between the two crossbars 24 and prevents these crossbars from retreating into the tube 27. The leaf spring 25 is fastened at its upper end in the tube 27 with the aid of the mounting part 26, which is passed through openings in the V / _a nd of the tube 27 and is equipped with a slot for receiving the leaf spring 25. The spring eyes 24 extend. their inside parallel to the vertical Ilantelfläche of the annular intermediate piece 22 and, as can be seen from the drawing, have a stepped projection inward in the area above the intermediate piece 22.

On a thinner continuation of the intermediate piece, which is directed downwards 22 a cap nut 23 is arranged hochschrauübar, the to u u s. Attachment of the rope 21 is used and before the attachment or after any removal of the tip of the ski pole 31

The tensioning of the rope 21 results in the illustrated mounting of the tip at the lower end of the rope 21 in that the ringförc'.ige intermediate piece 22 and with it the cap nut 23 on the inner stepped projections of the crossbars 24 find a fixed upper abutment that prevents further upward movement of these two parts. The tension of the rope 21 results from the fact that the crossbars 24, which protrude through openings in the wall of the tube 27 and are exposed on their outside to the pressure of the fixed lower end ring 29 of the tube 2, do not move upwards against this end ring 29 can be moved.

Conversely, the crossbars 24 can also be operated under the pressure of the pipe and the fixed locking ring 29 because of the clamped between them Intermediate piece 22 does not give way inward and thus also does not allow the tube 2 to move downward over the tube 27- I slide. For this reason, the retractable tip 5 remains during normal use of the ski pole firmly in their outer position.

The correct position of the intermediate piece 22 can be set with the aid of the cap nut 23 given the correct length of the rope 21 will; e.g., by screwing the cap nut 23 down, the intermediate piece 22 can be tightened up against the crossbars be pressed. If the intermediate piece (the locking ring) 22 is then in good contact with the crossbars 24, a further downward screwing will result the cap nut 23 to further tighten the rope 21.

The effectiveness of the arrangement shown in connection with a fall eu.f the ski pole is still determined by the ceiüen around üas s _e il 21 helical springs 28 and 32. The helical spring 28 is on both the cold part 26 and on the top. Part of the intermediate piece 22 attached and between

serve parts in a predetermined amount 'compressed. The η / Q helical spring 32 rests from above on the mounting part 26 or, alternatively, on an annular insert piece (not shown in the drawing) at the upper end of the insertion tube 27. At its upper end, this spring 32 is supported by the annular stop 33 which is fitted in the tube 2.

In the event of a fall in which a longitudinal impact occurs on the two ends of the ski pole, so that the upper end piece 6 of the locking elements as soon as the control rod 9 is moved downwards, the tightly tensioned rope 21 loosens automatically thereupon, when the tubes 1 and the rope 21 slide into one another, they loosen even more. Because of this relaxation of the Rope 21 there is an immediate stretching of the pressed together Helical spring 28. This pushes the intermediate piece 22 down from the space between the crossbars 24-. Since the crossbars 24 are then no longer supported from the inside, they can dom pressure of the pipe 2, which is over the locking ring 29 acts on them, no longer offer sufficient resistance. They therefore move into the inner space of the pipe 27. The tube 27 can n-.ua, if the ski pole continues to be a longitudinal one Pressure r.u £ j is exerted into the interior of the snow plate and the tube 2 draw back (the low back pressure of the coil spring 32 can easily be overcome). The top forms then no more danger. By one receding from the ground The tip of the ski pole can also promote the tilting of the ski pole will. Finally, it is advantageous to withdraw from a point directed towards the skier's body. if the ski pole is not immediately under the skier's body should tip or slide away. The last pressure exerted against the body by the snow plate 3o is considerably less dangerous.

The impact on the snow plate can also be genilderx through the design of this snow plate; a task, however can be solved in different ways.

If, after the retractable tip 5 has retreated, the pressure on the lower end of the ski pole wr; rc. so the displaceable tip 5 is automatically pushed back outwards into its starting position by d.-rc '^ rv.olc of the helical spring 32. If at this point in time the tubes 1 and 2 are still pushed into one another, that is to say also the rope 21 is still loose, the crossbars 24, which have returned to the starting position, prevent the tube 27 from being

can fall out of the ski pole.

The Kc-he of the intermediate piece 22 and the adjacent parts of the crossbars 24 can be controlled depending on the assessment of the security requirements, whether the ski pole tip is already with a slight or full downward movement of the upper end piece 6 of the locking elements or the control rod 9 or only during the one-another sliding of the Ro lire 1 and 2 should be retractable under pressure. X ::: In this case, all tubes of the ski pole (1, 2, 27) can be pushed into one another at about the same time. To a threshold value for the pushability of the tube 27, as it is achieved, for example, by a conical: The upper part of the intermediate piece 22 could be achieved by raising the height of the stepped projections in the leaf spring 25 on the same side, was compressed for the sake of greater safety, among other things.

The smallest changes are required for these figures. '' (JΠ In the fixed lower part 7 of the upper end piece 6 of the locking members are inserted separately 44, the guide pins and the Steuerun ^ sstange 9 directly attached. The tension spring 68 is wound in sections with three different diameters. The portion of the smallest diameter surrounds the control rod 9 below a round extension 69 of the control rod, the section with the next largest diameter surrounds the round extension 69 and the part of the control rod 9 connected above and is passed together with it through an opening in the lower holding part 34. The part of the spring 68 with the largest diameter lies in the interior of the annular continuation 42 on the handle part 34 »

Characterized in that the top contact point of the tension spring 68 is in its position is invariable, the extension point 69 of the control rod and with it the control rod 9 and the upper one can do this To hold the end piece 6 of the Ver.ciegelungsorgane in the uppermost position. In the event of a longitudinal blow on the ends of the ski pole and experiences the downward movement of said parts triggered thereby the spring 68 an extension. The advantage of such a design is that a spring, which is in their stress stretches, generally its function can be impaired less by a possible icing than a spring, which is compressed under stress.

According to the principle, the compression spring 19 used in the middle part of the ski pole, which expands during the downward displacement of the control rod 9, is also fundamentally not at risk of icing. The smaller compression spring 14 (FIG. 4), which is placed around the control rod 9 underneath the intermediate piece 10, can be protected from obstruction by icing by means of a strong anti-icing lubrication, eg ir.it silicone grease, among other things; However, as already stated, if the intermediate piece 1o is firmly connected to the control rod 9, it can also be dispensed with and replaced in its function by the spring ο or 6J, which is accommodated in the handle anyway and which might only have to be lengthened somewhat. The i'.Lr the tip l.:;ung used spring 23. (Fig. 9) expands when the rope 21 is loosened and is basically little or not guided even without sorting. The exhibiting area also used in the tip

feder 32 is not at risk with good permanent lubrication; dac Incidentally, the same also applies to the compression spring 8, which is used in the illustrated Embodiments is used in handle.

In this example, the gaps between the upper end piece must also be excluded from any obstruction due to ice accumulation the locking members and the holding part 34 or its continuation 42 with a very resilient closed cell foam filled in, namely in. the outer space with the help of the circumferential Foam ring 7o. With a favorable configuration can the cavities (gaps) required in this part of the handle are reduced in size and size. Ground If the inner interstices are combined to form a single larger interstice, this can be achieved by the inclusion of a gas-filled, easily compressible hollow body, e.g. made of plastic, which surrounds the control rod 9 in a ring shape.

Figure 11 shows an embodiment of the connecting zone of the two Pipes 1 and 2, essentially that shown in Pig 4 Execution corresponds, however, the outer sleeve 16, 16 a (ir Pig 1:15 »15 a) avoids.

In this case, the crossbars 11 are still covered by the tube 1, which is connected to the constrictions 71 directly on the top of the crossbars. The one for good mutual lubricity of the tubes 1 and 2 also required characteristics 52 in the upper part of the tube 2, which simultaneously pulls one apart further Prevent this Rohi'e are adapted in their size to the constriction 71. Also matched in size is the taper 71 a at the lower end of the tube 1.

In this embodiment, the lower tube 2 is slimmer than in the other exemplary embodiments already shown, which is additional Benefits in use brings about, namely a weight reduction in the lower part of the stock and one preferred by the buyers more conical shape of the ski pole. The function of the constriction 71 can also be more corresponding by means of an annular insert Profilgebv-iig überemoiuien -, verden, that from below in the Tube 1 inserted iüi.

The lower insert 73 simultaneously forms the upper Y / iderlager for the compressed helical spring 19 · This promotes how 1, 4 and 1-1, when the control rod moves downwards, its stretching causes a perfect, bending-free downward movement of the control rod 9. With the aid of the nut 74 which is screwed on the lower end of the control rod 9, the Helical spring 13 are pretensioned to the required extent, in any case this spring is weaker than the counteracting spring 8 or 68 accommodated in the handle.

From the lower end of the control rod 9, the rope 21 is also attached, which leads to the support tube of the retractable tip. the Cross bars 11 are enclosed on the outside by a two-part Llanüchette, e.g. made of plastic or metal » This consists of the upper part 15, which is fixed on the tube 1 and is attached resiliently, and from a lower part 15 a, which is on the upper part 15 is also firmly and firmly attached!; L.ar is attached, but rests on the lower tube 2 with good sliding properties.

FIG. 12b shows a cross section through the pipe 2 in FIG in Fig. 12 a marked sectional plane Λ-Α with removed Cuff lower part 15 a.

The two crossbars 11, which are each held in their outermost position by the helical springs 75, protrude through openings 55 in the pipe 2 to the outside and also fill part of the adjoining Rohr-IiinenrauiT.es. In the middle of the tube, between the coil springs 75 and the crossbars 11, is, with its longer cross-sectional axis parallel to the coil springs, the intermediate piece 1o arranged.

The intermediate piece 1o is firmly attached to the control rod 9. At the same time, the spring 8 housed in the handle takes over or 68 or another spring element housed in the edge handle and acting in the same way, the task of the omitted Spring K (Fij 4). These springs have, like the coil spring in Fig. 4 to fulfill a further special function: Are the tubes 1 and 2 according to their; -.

If the control rod 9 is moved so far downward in a longitudinal fall on the ski pole that the cylindrical part of the intermediate piece 1o is outside the space between the two crossbars 11, the crossbars 11 can under the pressure of the tubes 1 and 2, which are located on the Contact surface of the flange part with the crossbars 11 acts against the pressure of the springs Ί 5 scv / ie 8 or v /. 63 move back into the interior of the tube 2. Dair.it can slide the Hohr 1 together with the sleeve parts 15 and 15 a over the pipe 2.

The threshold for sliding the tubes 1 and 2 into one another is lower in this case than in the exemplary embodiment shown in FIG. 4, because the intermediate piece 1o can be moved more easily from the crossbars, outside of its flatter upper part, to the bottom.

Figure 13a shows a further embodiment for the locking members a telescopic safety ski pole3, With this type of execution, the tubes of the ski pole go through Scissor-like connected supports, which are housed lengthwise in the wider tube and supported against the upper end of the narrower tube are held in their mutual position. In the case of the present special Ausfünrungsbeispiel are in the upper tube 1 the supports 73 and 79 »which with their lower end against the annular upper end piece 84 of the lower Rohro 2 are supported.

As can also be seen from FIG. 13 c, the supports 70 and 79 are about in their middle rotatable together on 'one fixed in the pipe 1, fixed axis 83 mounted. If the control rod 9 is now moved downwards in the event of a fall on the ski pole, so the conically recessed control part 82 also becomes shifted downwards. By the downward movement of the conical inner surfaces of the control member 82, the upper ends and danit at the same time the lower ends of the supports 78 and 79 are also moved towards one another. By the fact that the lower ends of the supports 78 and are forcibly moved inwards, the parts 78 and 79 lose their support function. The pipe 2 can then be inserted into the pipe 1 until ZUJC axis 83 is inserted v / earth. By a higher arrangement of the axis 83 in the pipe 1 and by appropriate adaptation of the rest of the arrangement in the pipe 1, a very extensive sliding into one another can be achieved the ski pole allows grounding. If the scissor-like connection of the support parts is maintained, there are deviations from the illustrated rectilinear design of the supports, the shape of their attachment in the tube 1 and the control of their folding possible.

Fig. 13 a also shows the rope 21, which is used to support the retractable Point leads and in the present case is extended upwards to the conically recessed control part 82. at the downward movement of this part 82, with the loosening of the rope 21, the tip can be pushed in as described.

FIG. 13 b shows a cross section through the tube 1 in FIG in Fig. 13 a marked section plane A-A with a simultaneous view of the parts lying above in the pipe. The two Supports 78 and 79 are cranked. As a result, their upper ends lie at exactly opposite points in the conical Recess of the control part 82, although the supports in their central part, as can be seen from FIG. 13 c, only side by side get lost.

Figure 13c shows the Quersclaiitt through the tube 1 in the ά in Figure 15 marked Seimittebene 3-B with equilateral look up. To connect the support parts with scissors, it is also possible to bend these supports in the area of the connecting axis; the support parts are then in their entirety in the same plane.

FIG. 13 d shows a cross section through the tube in the Section plane C-C with a simultaneous view downwards. This figure shows the lower ends of the supports 78 and 79 in their position on the annular upper end piece 84 d'es tube 2. When scissors-like When the support parts 7 <3 and 79 are folded, they slide through the opening of the annular end part 84 downwards.

Figure 14 shows an embodiment of an inventive Safety ski pole with tubes 1 and 2 of the ski pole in the event of a fall on one of the two ends of the ski pole as well can be moved against each other, in which, however, no telescopic, instead there is an articulated connection between the two pipes.

Except for the different heights of the guide grooves 42, the upper end piece 6 of the locking members corresponds to the embodiment according to FIG Pig 2; likewise the execution of the detachable loop 4 (35 to 4o). The control rod 9 ends in the interior of the lower holding part 34 and is continued downward by the rope 21.

The connection of pipes 1 and 2, as shown, the same Have a diameter, takes place in the following manner. At the lower end of the tube 1 is with the aid of the annular insert 88 and with the help of a port setting piece 87 a screwed into it the ball 87 attached. The ball 87 and its upwardly directed port setting piece 87 a consist of a very solid material, e.g. made of high-strength steel, and are equipped with a longitudinal bore 86.

This ball 87 belonging to the upper tube 1 and firmly connected to it rests on a matching insert piece 89 of the lower tube 2; for this purpose a ball socket is provided in the upper part of the insert 89. The longitudinal bore 86 provided in the ball 87 continues in the insert piece 89 downwards. It is impossible for the ball 87 to jump out of its mounting position, since a further retaining part 9o is attached to the tube 2, which still engages around a part of the upper half of the ball. In this way, the ball is fixed, but can be swiveled well in all directions. The good mutual lockability of the tubes 1 and 2 also results from the fact that the connecting zone of these two tubes consists of an Ilan collar 92. an elastic material, e.g. · B. KunstgUiini, is enclosed.

In the figure outside-i is the locking of this pipe connection shown, the rigid connection of the tubes in the ski pole

This interlocking the pipe connection takes place in that from the bore 86 a dos insert piece 89 a very solid one, e.g. made of high-strength steel Pin 8p is also inserted into the longitudinal bore 86 of the ball 87. The parts 89 and 87 are through this pin 85, which fills the inner space of the bores 86 a and 86, in their mutual position atarrely fixed. . . ■ ', ·.

Uta at oino;:! When falling on the ski pole, pipes 1 and 2 against each other make movable to. can, the following requirements exist: The The locking pin 05 is connected to the shortened control rod 9 connected by the tensioned rope 21. XInch down the pin 85 continues in an extension that with the piston-like Crosspiece 91 completes. Between this piston-like cross-piece and the pipe lying above, an atomic piece 89 is around the pin 85 a helical spring 19 is laid down. This feather is weaker than the spring 0 housed in the handle and is zv / ischen the Parts 89 and 91 ^ usanuaengedxuckt. It occurs in the event of a fall the ski pole to a downward movement of the control notar.ge 9, so If the pin 85 is extended by the stretching of the spring 19 cus of its locking position, i.e. shifted out of the bore 86 in the ball 87. During this process, the handle remains leading part of the rope 21 stretched.

The part of the rope 21 that is at the lower end of the locking pino 85 is attached and leads to the retractable tip 5 with dieceia process at the same time loosely and thus enables the retractability the top.

Because the pipes 1 and 2 against each other during a fall become movable and the ski pole gives way to the side in this way, the ski pole immediately loses its dangerousness. He practically tilts i-a.; cr to the side. Will thereupon the PwOhrs 1 and 2 are brought back into a straight position, so the pin 85 can immediately move back under the action of the spring Ü return to its original position so that the tubes 1 and 2 are firmly connected again. At the same time the spring 19 is stimulated again; the Spitce 5 returns to its external position as described return. '.

In this case D it divides - not only öev streamlined buffers 3, but also the vertical holding part 34 of the handle from one Foam with a closed outer skin 45, in particular made from 3? (Integral foam). Both parts are made from one piece, so that a Gesant handle part 93 is created in which Buffer 3 and handle part 34 in their outer Fora -harmonically apart to develop.

This one-piece handle part 93 not only has the advantages of a uniform, elegant shape and that after all Sides closed construction. This handle part 93 is also in its entirety especially handv / arn and he offers the hand a comfortable elastic hold. The strength of the material can be adjusted without difficulty so that the buffer 3 Sufficiently soft and elastic when subjected to impact reacts that the saw grip but the hand of the skier also offers a sufficient, not too flexible hold. The achievement this correct hardness setting is facilitated by the fact that the formed foam body 93 in the area of Haiteteils 34, in dam the foam with the same skin formation has a low layer thickness, automatically has a greater strength than in the area of the buffer 3

In addition, the handle part 93 has in the area above the holding part 34 a special compressible zone 94, which in the present case Fall through a thinner wall of the handle part 93 at the level of the inner annular cavity 96 comes about. This The cavity can also be designed in a modified manner, e.g. higher arranged in the buffer, smaller or even with a If possible, filled with closed-cell elastic soft foam be.

In the present exemplary embodiment, the G-esanit-uriffteiles 33 is fastened to the upper ski pole tube 1 with the aid of the fixed core piece 99, which is inserted into the tube 1 from above. This solid core piece also has an annular upper port setting 42 with longitudinally directed guide grooves 43, as was already shown in a corresponding manner in the previous figures, for example Tlß 2. The connection of the fixed lower part 7 of the upper end piece 6 of the locking members, which is equipped with guide pins 44, is also carried out in a corresponding manner. The aforementioned core piece 99 has a cavity suitable for receiving the helical spring 8 in its interior. With the help of this helical spring 8, the upper end piece of the locking members 6 or 3 + 7 is held in its uppermost position. The upper end piece 41 of the control rod 9, which is screwed onto the control rod 9, serves as an intermediate piece between the helical spring 8 and the fixed lower part 7 of this upper end piece. This upper terminating piece 41 is equipped in its upper part with a screw slot 1oo lying in the cutting plane and therefore not hatched.

The detachable loop 4 is fastened to the handle in the following way: In order to give the buffer 3 the necessary "bond strength", the fixed disk 43 as an inner abutment is in the buffer, as shown in the previous figures is firmly connected to the lower part 7 of the upper end piece of the locking device by the intermediate piece 97 and the screw 46.

In this way, as in the figures already discussed above, the upper end piece can be prevented 6 moves downwards even with harmless loads. But since the loop 4 directly nit this upper end piece 6 the locking members is connected, on the other hand, it can be achieved that the ski pole tubes at an excessive, downward directed stress caused by the support parts of the leaf spring 9S can no longer be caught, be pushed into one another. This can result in certain extreme situations during a Fall e.An injury to the arm or other parts of the body that remain rigid in these situations can be prevented of the ski piece could arise. - Of course, if on these advantages are waived, an upwardly reaching fixed continuation can be provided on the fixed core piece 99, which by the buffer 3 leads to the outside and is equipped at its outer end with the fixed teeth 35 for holding the loop 4. It is also possible to use a Gesanit handle part of this type using a gas-filled elastic hollow buffer, usually under internal overpressure, woi) ei in particular the shape of the parts that are used to hold the loop would have to be changed.

The locking of the Rohrverriegelvaigsorgane in their uppermost position can be done in the present case above all by a locking device arranged directly below the handle 34, which can be constructed according to the principles explained in FIGS. 3 a to 8 d. In particular . In this case, a small rotary valve located inside the tube 1 is thought of, which is transverse to a special, non-circular Quorscüiiittsstücl ·. der StouGrun ₀ sstaii _t ; Q 9 posed

For the purpose of the Rohx reinforcement at the location of the Opening for the operating lever, the tube 1 can be surrounded by a fixed llanechette in which the corresponding Latching points are provided for the operating lever. Through a. Spring element with tension in the direction of the ski pole axis unintentional adjustment of the rotary valve can be made even more difficult will.

This figure also makes it clear once again that only a buffer of the type already shown in FIGS. 2 to 3b is suitable for a previously unknown protective effect also on the part of the To enable handles that are very easy to use at the same time made possible when the skier is supported from above on the handle. Just a thickening at the top of the Previous steps could not help here, because it would be both unwieldy with the appropriate size, but could also the hardness of an impact against the body does not arise from it attenuating not decisively attenuating).

Within the scope of the invention presented, and possibly both within the framework of the principles explained and the exemplary embodiments shown, many individual variations and modifications are possible. In addition, independent applications of individual elements of the invention are also possible: e.g. kojin, especially in children's ski poles, only one buffer and a retractable tip can be provided, which is connected to the upper end piece of the locking elements along the entire length of the ski pole by a taut rope . Corresponding to the embodiment of the retractable tip shown in FIG. 9, the intermediate piece used for locking in the connecting area of the tubes 1 and 2 can only be connected to the upper end piece of the locking members with a rope; at the same time, as with the retractable tip, an accelerated ;; Pushing the intermediate piece out of the area of the transverse groove <_: el 11 can be achieved. In a similar sense, the use of leaf springs with inwardly directed prestressing (12) can promote the specialization of the Sltistockronre, but other, perhaps less advantageous systems of pipe connection can also be used. .d -vorriü ₀ ylui-.g bewondcr. will.

In any case, however, I can designate organs which only serve to establish a connection between the Sicistockroiire under pressure and those organs which are triggered by displacement are the primary cause of locking or unlocking this otherwise movable pipe connection can form. ! These can be referred to directly as locking devices. This means that subordination to the basic principles presented is possible in any case.
