Abstract

The pole (1) has a non-circular, mainly triangular, cross-section, which is the same over its complete length, and a longitudinal row of holes in its top section. A locking bolt (9) engages into the holes (14). The bolt is located on the free end of a flexible tongue (10), which is positioned on a freely movable pole grip (4). The free tongue end is connected to a trigger (12), to release it and disconnect the locked connection (9,14). The trigger is ring-shaped. It surrounds the pole with free play, which is larger than the locking path of the bolt. The flexible tongue is positioned in the rear area of the grip, facing the ball of the hand holding the grip.

Description

The invention relates to a ski and hiking stick adjustable effective length at which the stick handle is along of the ski and hiking stick slidable and in the shifted Location can be determined.

A ski pole is known from DE-26 32 201 C3 Stick grip against the action of a spring along the Skistokkes is displaceable to use the spring force as a feed aid. If this feed aid is not required, the Stick handle on the ski pole can be fixed using a clamping device. This also allows different effective ones Set lengths, i.e. the distance between stick handle and Ski pole tip is changeable. The disadvantage here is on the one hand the use of a clamp that one in the area the clamping device requires an elastically deformable stick handle. The clamping device comprises a pivotable Lever with eccentric, which deforms the stick handle and so that it can be clamped onto the ski pole. Such clamps can change in their clamping effect over time subside, so that not always an absolutely unmovable Fixing the stick grip on the ski pole is guaranteed. Because of the conically tapering formation of the Ski poles must have a very high clamping effect, which requires high deformation forces and the setting of the Stick grip in the new location more difficult. Another disadvantage is that the adjustment of the stick handle in the direction of a Shortening the effective stick length against the effect of the Spring must be done, which is always a hard pad for the tip of the stick required to be able to apply the displacement force. In the touring area with a high soft snow cover a stick length adjustment only by putting on the stick tip possible on skis because the snow has too little resistance offers for this sliding movement. It is immediately visible that such an adjustment of the effective stick length is cumbersome and takes too long in many situations. This is particularly the case with rapid changes in direction Hang the case where the tourer or mountain hiker faces the mountain a shorter stick and a longer stick on the valley side.

The object of the invention is a ski and hiking stick create that quickly adaptable to the respective needs, is particularly variable in its effective length, wherein the length changed in each case can no longer be changed unintentionally is.

This task is the beginning of a ski and hiking stick explained type solved according to the invention in that the Ski and hiking stick deviate from the circular shape constant cross-section over the entire length and essentially in the upper half a lengthwise Has row of holes, in whose holes a locking pin can be snapped into place at the free end of a freely movable one Stick handle attached resilient tab is arranged and that the tab at its free end with a handle for deflecting the tab and thus to release the snap connection connected is.

Due to the free movement of the stick handle along the Stick and by locking it by means of a hole engaging locking pin on a resilient tab is held, a quick release of the locking connection and moving the stick handle to another position possible, making the ski and hiking stick very quick and practical its effective length can be changed without effort.

Very large differences in length can be set very quickly, there is a spring restricting the displacement is not present. The use of one on a resilient The latching pin held in place not only enables one quick release and re-engagement of the stick handle in the respective chosen location, but also ensures an immovable Holder for the stick handle on the stick. Clamp connections on the other hand, especially because of the conical Training the ski pole to apply very large forces enable a secure attachment of the stick handle to the stick, what when attaching and especially when loosening this Clamp connection connected with a large effort requires a correspondingly long operating time. Through the Cross-sectional design deviating from the circular shape, whereby the cross-section remains the same over the entire length of the stick is on the one hand a twisting of the stick handle opposite avoided the stick, which always causes the locking pin is securely snapped into one of the holes in the row of holes and on the other hand is also conical compared to the previously known downward tapering sticks that the Stick grip always a tight guide along the Stockes has, since there is no tapering of the stick that inevitably an increasing game between stick and The stick grip leads the further down the stick grip is moved becomes.

If in a further embodiment of the invention the handle formed as a ring surrounding the ski pole with play is, wherein the game exceeds the locking path of the locking pin, so is a safe operation created even when the operator is wearing thick gloves, in particular Mittens are wearing.

It is particularly advantageous here if the resilient tab is arranged in the rear region of the stick handle the palm of his hand facing him. On this way the ring can be operated with your fingers without the hand on the stick handle being loosened significantly ought to.

If in a further embodiment of the invention the ski and Walking stick has an essentially triangular cross section with equal legs and a shorter base, where the legs and the base are convex and to each other are connected by circular arc sections and wherein the row of holes is formed in the base, this will not only the anti-rotation lock of the Stick grip compared to the stick realized, but it will realized a particularly slim stick profile, in which it no longer necessary for design reasons - as was previously the case is to taper the stick down, which already mentioned advantages with a constant profile Floor can be achieved with an appealing exterior. Through the Formation of the row of holes in the base of the triangular profile is located on the back of the stick and is therefore protected against falling snow.

Around the ski and hiking stick quickly and safely the size to be able to adapt the user's default settings is provided in a further advantageous embodiment that the Ski and hiking stick is made in two parts and the lower one Sub-floor can be telescopically inserted into the upper sub-floor and that the lower part of the floor resilient to one inside Pushable locking pin that carries into the holes in the row of holes the upper part of the floor is clickable. It is true telescopically slidable and with a clamping device known ski poles that can be fixed in the shifted position, however, these clamping devices can often only be difficult to loosen, making the two parts of the stick difficult move against each other because of the conical shape the clamping forces of the stick must be very large. Due to the configuration according to the invention, the two Stick parts designed to be easily interlocking be, not only a by the resilient locking pin quick release, but also a secure fixing of the two Stick parts is made possible. Because of the circular shape different cross-sectional design of the ski and hiking sticks, especially through the triangular cross-sectional design and the formation of the stick with the same Cross section over its entire length, despite the division of the Stockes assured high stability in every position and a mutual twisting of the two parts of the stick is excluded, which ensures that the locking pin engages securely the holes of the row of holes is guaranteed. Because of the constant Cross-section are those that can be pushed into each other Stick parts against each other much better than this in the case of conically tapered floor parts in accordance with the known Training is the case.

When using the ski and hiking stick exclusively as a walking stick it is desirable to remove the stick plate, since it is not required for hiking in the mountains without snow and is often disturbing. With the previously known Ski poles are not a loosening of the stick plate or only possible with disproportionate effort. To this quickly combined ski and hiking poles for your needs of being able to switch from mountain hiking is another Embodiment of the invention provided that at a distance from The tip of the stick on the ski and hiking stick bounces into the stick Push-in locking pin is provided for fastening one with a guide sleeve and on the lower one Slidable stick plate serves as the guide sleeve is adapted to the profile of the ski pole and one Has hole for snapping the locking pin. Hereby is a quick and easy removal of the stick plate possible, the same when snow fields are reached can be quickly attached to the stick again.

Around the stick plate the different snow conditions adjust and if possible in the removed state Being able to carry it in a space-saving manner is further advantageous Embodiment of the invention provided that the stick plate has a base with which the guide sleeve is firmly connected is, as well as a laterally insertable in the base part Extension part includes, both inserted in its Location as well as in at least one extended position compared to the basic part in which he is the Floor plate area enlarged. The inserted end position is in particular for the space-saving carrying of the Stock plates or provided on hard snow surfaces.

A preferred embodiment is that the extension part U-shaped and with the base part and both legs encompass the stick within the base part with guide shoes formed on the front leg ends is that the free leg ends through a supplementary to the basic part in the inserted position Yoke are connected and that the base part and part of the adjacent legs are resilient and wear a locking pin that can be snapped into holes in the base part is. This configuration is not only a stable one Management of the extension part in the extended state created due to the formation of guide shoes, but the resilient design of the lower U-shaped part of the extension part with the locking pin enables one rapid change of the floor plate area.

a cross section along the line VV in Figure 1 by the ski and hiking stick in an enlarged cross section.

The ski and hiking stick comprises one from an upper part 1 and a lower part 2, which can be telescopically pushed into one another existing floor, which is denoted by a total of 3, as well as a stick handle 4 with a loop 5. At the lower end of the Stockes 3 is, as can be seen from Figures 3 and 4, in the A stick plate is provided near the stick tip 6, the total is designated by 7.

The ski and hiking stick essentially has one triangular cross section with equal legs 28 and one shorter base 29, with both the legs 28 and the base 29 are arched. The two legs 28 are through equally large circular arc sections 30 with the base 29 and the both legs are connected by a circular arc section 31 larger radius connected. Over the entire length is the Ski and hiking stick cylindrical, i.e. he points no taper to the tip of the stick. This configuration has the advantage that neither the two floor parts 2 or 3 against each other, still the stick handle 4 opposite the upper stick part 1 is rotatable.

The stick handle 4 is, as can be seen in particular from FIG. 2, on the upper floor part 1 in the direction of the double arrow 8 guided and by a locking pin 9 in its respective Location definable. For this purpose, the locking pin 9 arranged at the free end of a resilient tab 10 which in interior of the stick handle 4 is fastened by means of rivets 11. With the free end of the resilient tab 10, a ring 12 is also connected, which surrounds the upper part of the floor 1 with great play and is movable in the direction of the double arrow 13 to the Locking pin 9 in different holes 14 of the upper Stick part 1 is clickable to release from this locking. The game with which the ring 12 surrounds the stick is included larger than the locking path of the locking pin 9. Since any number Holes 14 can be provided in the upper sub-floor 1 the displacement of the stick handle 4 of any size. These holes 14 also serve to lock the lower floor part 2 opposite the upper stick part 1, which increases the stick length is changeable. For this purpose, the lower floor part 2 carries a resilient supported locking pin 15, as shown in Figure 1. The telescopic displaceability serves two stick parts 1 and 2 for setting a basic length of the Ski and hiking stick, while the possibility of moving the stick handle 4 to quickly change the effective The length of the stick in the terrain serves when the stick on the mountain side shortens and the valley-side stick extended in its effective length shall be. The effective length is the distance between stick handle and stick tip 6 to understand. Due to the triangular cross section of the two floor parts 1 and 2 ensures that due to the exact guidance Locking pin 9 and 15 securely in the holes 14 provided Snap the row of holes into place because there is no mutual rotation of the respective Parts is possible.

At the bottom of the ski and hiking stick is nearby the stick tip 6 of the stick plate 7 provided one Base part 16 and an extension part 17 includes, in Can be pulled out of the base part 16 in the direction of the arrow 18, in which it is slidably guided, as in particular Figure 4 emerges. The base part 16 is designed as a housing and has a guide sleeve on its upper surface 19 with which this base part 16 is held on the lower part 2 is and is displaceable relative to this. The guide sleeve 19 is adapted in cross section to the cross section of the floor, whereby the stick plate 7 is held non-rotatable. For Securing the floor plate 7 is a spring-loaded locking pin 20, which is provided on the lower floor part 2 and in a bore 21 of the guide sleeve 19 can be snapped into place. The extension part 17 is U-shaped, the free ends of the legs 22 are interconnected by a yoke 23, which in the inserted position of the extension part 17 the Base part 16 added. To guide the extension part 17 in the base part 16 are the front ends of the legs Guide shoes 24 provided. The base part 25 and part the adjacent legs 22 are elastic and carry a locking pin 26 in the holes 27 of the base part 16 is clickable. In the illustrated embodiment two holes 27 are provided, one hole the extension part 17 in the extended position accordingly Figure 3 and the other hole in the extension part secures the inserted position according to Figure 4.
