Abstract

The foldable walking-stick with a handle (5), in particular a hiking stick, mountaineering stick or the like, consists of several tubular parts (1, 2, 3) which can be inserted into one another and are penetrated by a rubber cord (18) which is attached in each case to the top and bottom tubular part (1, 3). An additional tubular part (4) is inserted in the top tubular part (1) so as to be displaceable with a locking mechanism so that the entire length of the stick can be adjusted and fixed. <IMAGE>

Description

Die Erfindung betrifft einen zusammenlegbaren Gehstock mit Handgriff, insbesondere Wanderstock, Bergstock od.dgl., welcher aus mehreren, ineinandersteckbaren Rohrteilen besteht, die von einem elastischen Spannstrang, z.B. einer Gummischnur durchzogen sind, die jeweils am oberen und unteren endseitigen Rohrteil befestigt ist.The invention relates to a collapsible walking stick with a handle, in particular a hiking stick, mountain stick or the like. a rubber cord, which is attached to the upper and lower end pipe part.

Derartige Stöcke sind leicht zerlegbar und können dann in einem verhältnismäßig kleinen Etui untergebracht werden. Wegen der unterschiedlichen Körpergröße der einen Stock tragenden Personen müssen diese Stöcke mit unterschiedlichen Gesamtlängen erzeugt werden, wodurch sich der Herstellungsaufwand erhöht. Außerdem hat sich gezeigt, daß die Gesamtlänge eines Stockes z.B. bei Bergauf­wanderungen kleiner sein sollte als bei Bergabwanderungen, d.h. es müßten eigentlich zwei Stöcke unterschiedlicher Gesamtlänge verwendet werden. Es ist zwar ein Stock bekannt, der dieser Anforderung genügt, indem der Stock aus einem oberen Rohrteil mit Handgriff und einem unteren Rohrteil besteht, der im oberen Rohrteil verschiebbar eingesteckt ist und einen Verriegelungs­mechanismus aufweist, sodaß die Gesamtlänge des Stocks einstell- und fixierbar ist, u.zw. zwischen maximaler und etwa halber Gesamtlänge. D.h., der Stock nimmt im kürzesten Zustand noch einen verhältnismäßig großen Raum ein.Such sticks are easy to disassemble and can then be accommodated in a relatively small case. Because of the different heights of the people carrying a stick, these sticks have to be produced with different overall lengths, which increases the manufacturing effort. In addition, it has been shown that the total length of a stick, for example when hiking uphill, should be smaller than when hiking downhill, ie two sticks of different overall length should actually be used. A stick is known which meets this requirement in that the stick consists of an upper tube part with a handle and a lower tube part which is slidably inserted in the upper tube part and has a locking mechanism so that the total length of the stick can be adjusted and fixed, etc. between maximum and about half Overall length. Ie, the stick still occupies a relatively large space in the shortest state.

Durch die FR-PS 2 392 622 ist ein aus zwei ineinandergesteckten Rohrteilen bestehender Gehstock bekannt, dessen Länge schritt­weise verstellbar ist. Zu diesem Zweck sind in beiden Rohrteilen Querbohrungen vorgesehen, durch welche ein Gewindestift mit Gegenmutter einsteckbar ist.From FR-PS 2 392 622 a walking stick consisting of two nested pipe parts is known, the length of which is gradually adjustable. For this purpose, cross bores are provided in both pipe parts, through which a threaded pin with lock nut can be inserted.

Aufgabe der Erfindung ist die Schaffung eines Stocks, welcher einerseits bei Nichtgebrauch einen kleinen Raum einnimmt und anderseits bei Gebrauch in seiner Gesamtlänge stetig verstellbar und fixierbar ist.The object of the invention is to create a stick which, on the one hand, occupies a small space when not in use and, on the other hand, is continuously adjustable and fixable in its entire length when in use.

Dies wird bei einem Stock der eingangs erwähnten Art erfindungs­gemäß dadurch erreicht, daß zur Verstellung der Gesamtlänge des Stocks zwei Rohrteile mit einem Verriegelungsmechanismus verbunden sind, und daß der Verriegelungsmechanismus eine stetige Verstellung der Gesamtlänge des Stockes zuläßt.This is achieved according to the invention in the case of a stick of the type mentioned at the outset in that two tube parts are connected to a locking mechanism in order to adjust the total length of the stick, and in that the locking mechanism permits a constant adjustment of the total length of the stick.

Die Erfindung wird anschließend anhand eines bevorzugten Ausfüh­rungsbeispiels mit Hilfe der Zeichnung erläutert. Es zeigen

The invention is subsequently explained on the basis of a preferred exemplary embodiment with the aid of the drawing. Show it
  • 1 is a view of a walking stick according to the invention consisting of four tubular parts,
  • 2 shows a cross section through the stick according to FIG. 1 in the area of the locking mechanism,

In Fig. 1 bezeichnen 1,2 und 3 drei jeweils ineinandersteckbare, erste, zweite und dritte Rohrteile, wobei die Rohrteile 1 und 2 im wesentlichen zylindrisch sind, während sich der Rohrteil 3 konisch zur Spitze verjüngt. In den ersten Rohrteil 1 ist ein vierter Rohrteil 4 verschiebbar eingesteckt, welcher den Hand­griff 5 trägt. Am Ende des dritten Rohrteils 3 ist ein Gummistoppel 6 aufgesteckt, der jederzeit abnehmbar ist, sodaß z.B. eine Stahlspitze (nicht dargestellt) frei wird. Der Gummi­stoppel 6 findet auf Normalstraßen Anwendung, während sich die Stahlspitze für Gelände mit Eis und Schnee eignet. Es kann auch jederzeit ein Schneeteller (nicht dargestellt) in Form eines Gelenk- oder Kugeltellers montiert werden, welcher sich dem jeweiligen Gelände anpaßt. Der Handgriff 5 kann auch mit einer Schlaufe (nicht dargestellt) versehen sein, sodaß man den Stock bei Bedarf am Handgelenk hängen lassen kann.In Fig. 1, 1, 2 and 3 designate three, first, second and third pipe parts which can be plugged into one another, the pipe parts 1 and 2 being essentially cylindrical, while the pipe part 3 tapers conically towards the tip. A fourth tube part 4, which carries the handle 5, is slidably inserted into the first tube part 1. At the end of the third tube part 3, a rubber stub 6 is attached, which can be removed at any time, so that e.g. a steel tip (not shown) becomes free. The rubber stubble 6 is used on normal roads, while the steel tip is suitable for terrain with ice and snow. A snow plate (not shown) in the form of an articulated or spherical plate can also be fitted at any time, which adapts to the respective terrain. The handle 5 can also be provided with a loop (not shown) so that the stick can be hung on the wrist if necessary.

Der Verriegelungsmechanismus zwischen dem ersten Rohrteil 1 und dem vierten Rohrteil 4 besteht darin, daß das dem Handgriff 5 gegenüberliegende Ende des vierten Rohrteils einen Spreizdübel 7, vorzugsweise aus Kunststoff oder Metall, trägt, der im verriegel­ten Zustand eine starre Verbindung zwischen den beiden Rohrteilen 1 und 4 herstellt, wie später erläutert wird. Das Ende des vierten Rohrteils 4 weist anfangs einen leicht konischen Bereich 8 auf, der in einen stark konischen Bereich 9 übergeht und sich zunächst als Gewindeschaft 10 und anschließend als gewindeloser Schaft 11 kleineren Durchmessers als das Gewinde fortsetzt. Am Ende des Schaftes 11 ist eine Sicherungsscheibe 12, z.B. eine federnde Scheibe mit Innenverzahnung od.dgl. aufgesteckt. Der Spreizdübel 7 besteht aus einem außen und innen konisch geformten Bereich, der am Umfang z.B. vier Längsschlitze 13 aufweist, sodaß vier Spreizarme 14 gebildet werden. Der äußere Konus verläuft flacher als der innere Konus, sodaß ein keilförmiger Querschnitt der Spreizarme 13 entsteht (Fig.2) An den konischen Bereich des Spreizdübels 7 schließt ein im wesentlichen zylindrischer Bereich mit einem Innengewinde 15 an. Am Übergang des Rohrteils 1 zum Rohrteil 4 ist eine Schutzkappe 16, vorzugsweise aus Kunststoff, auf den Rohrteil 1 aufgesteckt.The locking mechanism between the first tube part 1 and the fourth tube part 4 is that the end of the fourth tube part opposite the handle 5 carries an expansion plug 7, preferably made of plastic or metal, which in the locked state has a rigid connection between the two tube parts 1 and 4, as will be explained later. The end of the fourth pipe part 4 initially has a slightly conical area 8 which merges into a strongly conical area 9 and continues initially as a threaded shaft 10 and then as a threadless shaft 11 of smaller diameter than the thread. At the end of the shaft 11 is a locking washer 12 or the like, for example a resilient washer with internal teeth. attached. The expansion dowel 7 consists of an externally and internally conically shaped area which, for example, has four longitudinal slots 13 on the circumference, so that four expansion arms 14 are formed. The outer cone is flatter than the inner cone, so that a wedge-shaped cross-section the spreading arms 13 are formed (FIG. 2). The conical region of the expansion dowel 7 is adjoined by an essentially cylindrical region with an internal thread 15. At the transition from the pipe part 1 to the pipe part 4, a protective cap 16, preferably made of plastic, is placed on the pipe part 1.

Fig. 3 zeigt die Steckverbindung zwischen dem ersten Rohrteil 1 und dem zweiten Rohrteil 2. Zu diesem Zweck weist der erste Rohr­teil 1 einen Endbereich mit verringertem Außendurchmesser auf, der im wesentlichen gleich oder etwas kleiner als der Innendurch­messer des zweiten Rohrteils 2 ist. Bei der in Fig. 4 dargestellten Steckverbindung zwischen dem zweiten Rohrteil 2 und dem Rohrteil 3 weist der Rohrteil 3 einen Außendurchmesser auf, der im wesentlichen gleich oder etwas kleiner als der Innendurch­messer des dritten Rohrteils 3 ist, wobei eine Umfangsrille 17 im Rohrteil 2 als Anschlag für den Rohrteil 3 dient. Wie aus Fig. 1 ersichtlich ist, verbindet eine Gummischnur 18 die Rohrteile 1 bis 3 untereinander. Die Enden der Gummischnur 18 sind in den Rohrteilen 1 und 3 befestigt, wobei die Gummischnur 18 unter einer leichten Vorspannung steht.3 shows the plug connection between the first pipe part 1 and the second pipe part 2. For this purpose, the first pipe part 1 has an end region with a reduced outer diameter which is essentially the same or slightly smaller than the inner diameter of the second pipe part 2. In the plug connection shown in Fig. 4 between the second pipe part 2 and the pipe part 3, the pipe part 3 has an outer diameter which is substantially the same or slightly smaller than the inner diameter of the third pipe part 3, with a circumferential groove 17 in the pipe part 2 as a stop serves for the pipe part 3. As can be seen from Fig. 1, a rubber cord 18 connects the pipe parts 1 to 3 with each other. The ends of the rubber cord 18 are fastened in the tube parts 1 and 3, the rubber cord 18 being under a slight prestress.

Fig. 5 zeigt den Stock im zusammengelegten Zustand, wobei der vierte Rohrteil 4 nahezu vollständig in den ersten Rohrteil 1 eingeschoben ist. Um den Stock in den in Fig. 6 dargestellten Gebrauchszustand zu bringen, werden zunächst die Rohrteile 1 bis 3 zusammengesteckt, wobei die vorgespannte Gummischnur 18 unter­stützend wirkt, worauf der vierte Rohrteil 4 mit dem Handgriff 5 soweit aus dem ersten Rohrteil 1 herausgezogen wird, bis die gewünschte Gesamtlänge des Stockes erreicht ist. Dies erfolgt im entriegelten Zustand des Verriegelungsmechanismus, wie in Fig. 2 dargestellt. D.h das Innengewinde 15 des Spreizdübels 7 befindet sich im Bereich des gewindelosen Schaftes 11. Hält man nun den Rohrteil 1 mit einer Hand und dreht man mit der anderen Hand den vierten Rohrteil 4 mit dem Handgriff 5 unter gleichzeitiger Anwendung eines leichten Druckes in Richtung zum Stockende, so kommt der Gewindeschaft 10 in Eingriff mit dem Innengewinde 15 des Spreizdübels 7, wobei die Reibung der Spreizarme 14 mit der Innenwand der ersten Rohrteils 1 eine Drehung des Spreizdübels 7 verhindert. Der maximale Durchmesser des Spreizdübels 7 an den Enden der Spreizarme 14 ist im ausgebauten Zustand des Spreiz­dübels 7 größer als der Innendurchmesser des ersten Rohrteils 1 gewählt, sodaß die Spreizarme 14 im eingebauten Zustand des Spreizdübels 7 federnd gegen die Innenwand des ersten Rohrteils 1 drücken, wodurch die Reibung erhöht wird. Bei Fortsetzung der Drehbewegung wandert der Spreizdübel 7 somit in Richtung zum stark konischen Bereich 9 des vierten Rohrteils 4, bis die Enden der keilförmigen Spreizarme 14 den Übergang zwischen dem stark konischen Bereich 9 und dem leicht konischen Bereich 8 berühren, anschließend aufgespreizt werden und in den Raum zwischen dem leicht konischen Bereich 8 und der Innenwand der ersten Rohrteils 1 ein­dringen, sodaß der erste Rohrteil 1 mit dem vierten Rohrteil 4 fest verkeilt wird und der Stock gebrauchsfertig ist. Wünscht man den Stock wieder zu zerlegen oder die Gesamtlänge zu verändern, so braucht man nur den vierten Rohrteil 4 in die umgekehrte Dreh­richtung so lange zu verdrehen, bis sich die Spreizarme 14 außer­halb des leicht konischen Bereiches 8 des ersten Rohrteils 1 befinden, bzw. bis der Spreizdübel 7 wieder die in Fig. 2 darge­stellte Lage einnimmt, wobei die Sicherungsscheibe 14 ein Loslösen des Spreizdübels 7 vom Schaft 11 verhindert.Fig. 5 shows the stick in the collapsed state, the fourth pipe part 4 is almost completely inserted into the first pipe part 1. In order to bring the stick into the state of use shown in FIG. 6, the pipe parts 1 to 3 are first put together, the prestressed rubber cord 18 having a supporting effect, whereupon the fourth pipe part 4 is pulled out of the first pipe part 1 with the handle 5 until the desired total length of the stick has been reached. This takes place in the unlocked state of the locking mechanism, as shown in FIG. 2. Ie the internal thread 15 of the expansion anchor 7 is located in the area of the threadless shaft 11. Now hold the pipe part 1 with one hand and with the other hand turn the fourth pipe part 4 with the handle 5 while simultaneously Applying a slight pressure towards the end of the stick, the threaded shaft 10 comes into engagement with the internal thread 15 of the expansion anchor 7, the friction of the expansion arms 14 with the inner wall of the first pipe part 1 preventing rotation of the expansion anchor 7. The maximum diameter of the expansion dowel 7 at the ends of the expansion arms 14 is larger than the inside diameter of the first pipe part 1 when the expansion dowel 7 is removed, so that the expansion arms 14 press resiliently against the inner wall of the first pipe part 1 when the expansion dowel 7 is installed, whereby the friction is increased. As the rotational movement continues, the expansion dowel 7 thus moves in the direction of the strongly conical region 9 of the fourth pipe part 4 until the ends of the wedge-shaped expansion arms 14 touch the transition between the strongly conical region 9 and the slightly conical region 8, then are expanded and into the Penetrate space between the slightly conical area 8 and the inner wall of the first tube part 1, so that the first tube part 1 is firmly wedged with the fourth tube part 4 and the stick is ready for use. If you want to disassemble the stick again or change the overall length, you only need to turn the fourth pipe part 4 in the opposite direction until the spreading arms 14 are outside the slightly conical area 8 of the first pipe part 1, or until the expansion anchor 7 again assumes the position shown in FIG. 2, the locking washer 14 preventing the expansion anchor 7 from detaching from the shaft 11.

Beim dargestellten Ausführungsbeispiel ist der Verriegelungs­mechanismus zwischen dem ersten und vierten Rohrteil 1 und 4 vorgesehen. Es besteht auch die Möglichkeit, den Verriegelungs­mechanismus zwischen dem zweiten und dritten Rohrteil 2 und 3 an­zuordnen, wobei dann die Verbindung zwischen dem ersten und vierten Rohrteil 1 und 4 als Steckverbindung ausgeführt ist und die Gummischnur 18 die Rohrteile 4,1 und 2 verbindet.In the illustrated embodiment, the locking mechanism is provided between the first and fourth tubular parts 1 and 4. There is also the possibility of arranging the locking mechanism between the second and third tube parts 2 and 3, in which case the connection between the first and fourth tube parts 1 and 4 is designed as a plug connection and the rubber cord 18 connects the tube parts 4, 1 and 2.
