Abstract

Accessories, especially a handle (6) and a stick buffer (9) or a stick tip can be connected in an exchangeable manner to a stick shaft consisting of two tubes (1, 2) which are displaceable one inside the other. Connected to one of the tubes (2) is a coupling device (14, 15, 19) which connects the two tubes (1, 2) of the stick shaft to each other in a tension and pressure resistant manner. The coupling device can be detached by pushbutton (29) via a linkage (18) in order to displace the two tubes (1, 2) one inside the other and thus to adjust the length of the shaft as required. The infinitely variable adjustment of the shaft length and the different accessories result in an optimum, versatile usability of the stick. <IMAGE>

Description

Die vorliegende Erfindung betrifft einen Universalstockgemäss Oberbegriff des Anspruchs 1. Ein derartiger Stock zur wahlweisen Befestigung eines Eispickels oder einer Schneeschaufel ist in der EP-A-0 191 917 beschrieben. Es sind auch Mittel vorgesehen, um die beiden Rohre stumpf zu verbinden und als Lawinenstange zu verwenden. Das gegenseitige Kuppeln der beiden Rohre des Stockes erfolgt hierbei durch gegenseitiges Verdrehen der Rohre, womit je nach Drehrichtung ein Spreizkonus in eine Spreizhülse eindringt oder aus derselben zurückgezogen wird, um entsprechend die Rohre zu kuppeln bzw. zu entkuppeln. Dieses gegenseitige Verdrehen um eine unbestimmte Drehbewegung ist insofern ungünstig, als dabei die gegenseitige Orientierung der an den freien Rohrenden angebrachten Teile, z.B. Griffe und Werkzeuge, nicht erhalten bleibt. Es ist auch ungewiß, ob gerade beim Einsatz in Schnee und Eis die mit Spiel ineinandergreifenden Rohre des Gestänges stets gegenseitig verdrehbar bleiben.The present invention relates to a universal stick according to the preamble of claim 1. Such a stick for the optional attachment of an ice ax or a snow shovel is described in EP-A-0 191 917. Means are also provided for bluntly connecting the two tubes and using them as an avalanche pole. The mutual coupling of the two tubes of the stick takes place by mutually rotating the tubes, with which, depending on the direction of rotation, an expansion cone penetrates or is withdrawn from an expansion sleeve in order to couple or uncouple the tubes accordingly. This mutual twisting by an indefinite rotary movement is disadvantageous in that the mutual orientation of the parts attached to the free pipe ends, e.g. Handles and tools, not preserved. It is also uncertain whether the tubes of the boom, which interlock with play, always remain mutually rotatable, especially when used in snow and ice.

Aus der DE-A-2 140 450 ist ein aus drei Rohrteilen zusammenbaubarer Stock bekannt, der insbesondere als Ski- und Wanderstock mit einem Griff bzw. mit einem Schneeteller oder dergleichen versehen werden kann. In diesem Falle ist jedoch keine stufenlose Einstellung der Stocklänge vorgesehen.DE-A-2 140 450 discloses a stick which can be assembled from three tubular parts and which can be provided with a handle or a snow plate or the like, in particular as a ski and hiking stick. In this case, however, there is no continuous adjustment of the stick length.

Aus der FR-A-2 267 808 ist ein längenverstellbarer Skistock bekannt, bei dem im einen Stockteil ein unter Federkraft stehender Spreizkonus eine spreizbare Kupplungshülse gegen die Innenseite des anderen Stockteils drückt. Durch Druck auf den Stockteller nach unten kann der Spreizkonus entgegen der Federkraft ausgerückt werden, um die Stockteile ineinander zu verschieben. Nachteilig ist hierbei, dass der Teller nicht fest an seinem Stockteil angebracht ist und dass durch äussere Krafteinwirkung auf den Teller die Stockteile ungewollt entkuppelt werden können.From FR-A-2 267 808 a length-adjustable ski pole is known, in which an expansion cone under spring force in one floor part presses an expandable coupling sleeve against the inside of the other floor part. By pressing down on the stick plate, the expansion cone can be disengaged against the spring force in order to move the stick parts into each other. The disadvantage here is that the Plate is not firmly attached to its stick part and that the stick parts can be unintentionally uncoupled by external force on the plate.

Aus der FR-A-1 430 274 ist eine Kupplung bekannt, bei welcher ebenfalls ein Spreizkonus auf eine spreizbare Hülse wirkt. Der Spreizkonus ist mit einer Spindel verbunden, die in einem Gewinde der Hülse drehbar ist, und die Hülse ist durch eine federnde Reibungsbremse gegen Drehung gesichert. Diese Ausführung ist teuer und störungsanfällig, und sie erfordert eine Relativbewegung zwischen den zu verbindenden Teilen.From FR-A-1 430 274 a coupling is known in which an expansion cone also acts on an expandable sleeve. The expansion cone is connected to a spindle which is rotatable in a thread of the sleeve, and the sleeve is secured against rotation by a resilient friction brake. This design is expensive and prone to failure, and it requires a relative movement between the parts to be connected.

Aus der DE-A-28 34 260 ist ein längenverstellbaren Skistock bekannt, dessen Teile mittels eines unter Axialdruck spreizbaren Körpers gekuppelt sind. Zur Belastung bzw. Entlastung des spreizbaren Korpers ist ebenfalls eine Spindel vorhanden, was eine gegenseitige Verdrehung der Stockteile zum Kuppeln bzw. Entkuppeln erfordert.From DE-A-28 34 260 a length-adjustable ski pole is known, the parts of which are coupled by means of a body which can be expanded under axial pressure. A spindle is also provided for loading or unloading the expandable body, which requires a mutual rotation of the stick parts for coupling or uncoupling.

Ziel vorliegender Erfindung ist es, einen stufenlos verstellbaren Stock für vielseitige Verwendung zu schaffen, der sicher und unter gleichbleibenden Bedingungen einfach bedienbar ist. Dieses Ziel wird erreicht mit den Massnahmen gemäss dem kennzeichnenden Teil des Anspruchs 1. Das Kuppeln und Entkuppeln der Rohre erfordert hierbei keine gegenseitige Verdrehung der Rohre. Eine besondere Vereinfachung liegt darin, dass die Rohre normalerweise unter Federwirkung gekuppelt sind und durch einfachen Druck entkuppelt werden können.The aim of the present invention is to create a continuously adjustable stick for versatile use, which is safe and easy to operate under constant conditions. This goal is achieved with the measures according to the characterizing part of claim 1. The coupling and uncoupling of the pipes does not require any mutual twisting of the pipes. A particular simplification is that the pipes are normally coupled under spring action and can be uncoupled by simple pressure.

Die Erfindung wird nun anhand eines in der Zeichnung dargestellten Ausführungsbeispiels und Anwendungsbeispiels näher erläutert.

Der dargestellte Universal-Stock weist einen Schaft auf, bestehend aus einem oberen, äusseren Rohr 1 grösseren Durchmessers und einem unteren, inneren Rohr 2 kleineren Durchmessers, welches verschiebbar in das untere Ende des Rohrs 1 eingreift und vom unteren, verjüngten Ende des Rohres 1 geführt ist. In das obere Ende des äusseren Rohres 1 ist ein Federbügel 3 eingesetzt, welcher einen Sicherungsknopf 4 normalerweise in der dargestellten äusseren Lage hält, in welcher dieser Sicherungsknopf 4 z.B. in ein durchgehendes Loch 5 eines Handgriffs 6 mit Handschlaufe 6a eingreift und diesen Handgriff auf dem Rohr 1 sichert. Der Handgriff 6 weist eine Bohrung 7 auf, in welcher das Rohr 1 praktisch spielfrei eingreift, sodass der Handgriff 6 stabil mit dem Rohr 7 verbunden ist. Gemäss Figur 1 greift ein Kupplungsrohr 8 eines Stockpuffers 9 in das untere Ende des Rohrs 2 ein. Im Kupplungsrohr 8 ist ein Sicherungsknopf 10, ähnlich dem Sicherungsknopf 4, mittels eines Federbügels 11 gehalten und greift bei gemäss Figur 1 mit dem Rohr 2 gekuppeltem Kupplungsrohr 8 in ein Loch 12 des Rohres 2 ein und sichert damit den Stockpuffer 9 am unteren Ende des Rohres 2.The universal stick shown has a shaft consisting of an upper, outer tube 1 of larger diameter and a lower, inner tube 2 of smaller diameter, which slidably engages in the lower end of tube 1 and is guided by the lower, tapered end of tube 1 is. In the upper end of the outer tube 1, a spring clip 3 is inserted, which normally holds a safety button 4 in the outer position shown, in which this safety button 4 e.g. engages in a through hole 5 of a handle 6 with a loop 6a and secures this handle on the tube 1. The handle 6 has a bore 7, in which the tube 1 engages practically without play, so that the handle 6 is stably connected to the tube 7. According to FIG. 1, a coupling tube 8 of a stick buffer 9 engages in the lower end of tube 2. In the coupling tube 8, a securing button 10, similar to the securing button 4, is held by means of a spring clip 11 and engages in a coupling tube 8 coupled to the tube 2 according to FIG. 1 in a hole 12 in the tube 2 and thus secures the stick buffer 9 at the lower end of the tube 2nd

Im Aussenrohr 1 befindet sich eine mit dem Innenrohr 2 verbundene Kupplungsvorrichtung 13, welche der zug- und druckfesten Verbindung der Rohre 1 und 2 dient. Die eigentlichen Kupplungsorgane sind ein Konus 14 und ein ihn umgebender Kranz von Kugeln 15. Die Kugeln 15 sind in einem axial verschiebbaren Käfig 16 gehalten, der mittels eines Querstiftes 17 mit einer axial verschiebbaren Auslösestange 18 verbunden ist. Zwischen dem oberen Ende der Auslösestange 18 und dem Konus 14 wirkt eine Druckfeder 19, welche den Konus gegenüber dem mit der Auslösestange 18 verbundenen Käfig 16 und somit den Kugeln 15 nach oben drückt. Damit presst der Konus 14 die Kugeln 15 radial gegen die Innenwand des Rohres 1 an, womit die zug- und drucksichere Verbindung der Rohre 1 und 2 sichergestellt ist. Der Konus 14 besteht aus einem Stück mit einem Kolben 20. In zwei Querbohrungen dieses Kolbens 20 befinden sich Druckfedern 21, welche Kugeln 22 gegen die Innenwand des Rohres 1 drücken. Die Elemente 20 bis 22 wirken als Bremse, welche eine axiale Verschiebung des Konus 14 im Rohr 1 nur unter Ueberwindung einer bestimmten Kraft erlaubt. Das obere Ende der Auslösestange 18 ist in einer Hülse 23 axial verschiebbar geführt. Die Hülse 23 weist eine Ringsicke 24 auf, in welche ein hineingedrückter Ringwulst 25 des Rohres 2 eingreift und die Hülse 23 im Rohr 2 sichert. Das untere Ende der Auslösestange 18 ist mittels eines Querstiftes 26 mit einem im Rohr 2 verschiebbaren Kolben 27 gekuppelt, welcher am unteren Ende einen flachen Konus 28 aufweist. Auf diese konische Fläche 28 kann der innere Rand eines Drückers 29 wirken, welcher normalerweise durch eine Druckfeder 30 in der dargestellten äusseren, unwirksamen Stellung gehalten ist. Durch Hineindrücken dieses Drückers 29 kann der Kolben 27 und damit die Auslösestange 18 axial nach oben verschoben werden. Mit der Auslösestange 18 wird hierbei auch der Käfig 16 mit den Kugeln 15 gegenüber dem durch die Bremse mit genügender Kraft, also mit einer die Kraft der Feder 19 übersteigenden Bremskraft gehaltenen Konus 14, angehoben. Damit sind die Rohre 1 und 2 voneinander entkuppelt und können ineinander verschoben werden. Die Rohre 1 und 2 und deren Verschiebungsweg kann beispielsweise so gewählt werden, dass der Stockschaft im zusammengeschobenen Zu stand etwa 0,70 m und bei ganz ausgezogenem Zustand etwa 1,20 m beträgt.In the outer tube 1 there is a coupling device 13 which is connected to the inner tube 2 and which serves for the tensile and pressure-resistant connection of the tubes 1 and 2. The actual coupling members are a cone 14 and one surrounding ring of balls 15. The balls 15 are held in an axially displaceable cage 16 which is connected by means of a cross pin 17 to an axially displaceable release rod 18. A compression spring 19 acts between the upper end of the release rod 18 and the cone 14, which presses the cone upwards relative to the cage 16 connected to the release rod 18 and thus the balls 15. The cone 14 thus presses the balls 15 radially against the inner wall of the tube 1, thereby ensuring the connection of the tubes 1 and 2 that is secure against tension and compression. The cone 14 consists of one piece with a piston 20. In two transverse bores of this piston 20 there are compression springs 21 which press balls 22 against the inner wall of the tube 1. The elements 20 to 22 act as a brake, which allows an axial displacement of the cone 14 in the tube 1 only by overcoming a certain force. The upper end of the trigger rod 18 is guided axially displaceably in a sleeve 23. The sleeve 23 has an annular bead 24 into which an annular bead 25 of the tube 2 which is pressed engages and secures the sleeve 23 in the tube 2. The lower end of the release rod 18 is coupled by means of a cross pin 26 to a piston 27 which can be displaced in the tube 2 and which has a flat cone 28 at the lower end. The inner edge of a pusher 29 can act on this conical surface 28, which is normally held in the outer, inactive position shown by a compression spring 30. By pushing this pusher 29, the piston 27 and thus the release rod 18 can be moved axially upwards. With the release rod 18, the cage 16 with the balls 15 is also raised relative to the cone 14 held by the brake with sufficient force, that is to say with a cone 14 which exceeds the force of the spring 19. The pipes 1 and 2 are thus uncoupled from one another and can be shifted into one another. The tubes 1 and 2 and their displacement path can be chosen for example that the stock shaft is about 0.70 m when pushed together and about 1.20 m when fully extended.

Die Figuren 2 bis 5 zeigen, in etwas kleinerem Massstab als Figur 1, die vielseitige Verwendbarkeit und die einfache Bedienung des Stockes. Der Handgriff 6 ist, wie die Figuren 2 und 3 zeigen, als kombinierter Gehstockgriff und Skistockgriff ausgebildet und verwendbar. In der Position nach Figuren 1 und 2 steht der Griff quer zur Längsachse des Stockes und ist mittels der Bohrungen 5 und 7 gemäss Figur 1 mit demselben gekuppelt. Der Handgriff kann aber in der Position nach Figur 3 mit entsprechenden Bohrungen 5′ und 7′ in Richtung der Längsachse mit dem Stockschaft verbunden werden. Entsprechend können mit dem unteren Ende des Rohres 2 wahlweise der Puffer 8, 9, gemäss Figur 1, eine Stockspitze 31 mit einem entsprechenden Kupplungsrohr 32 und einem Sicherungsknopf 10 oder aber ein Schneeteller 33 mit Skistockspitze 34 mit einem entsprechenden Kupplungsrohr 35 und einem Sicherungsknopf 10 (Fig. 5) mit dem unteren Ende des Stockschaftes verbunden werden. Auf einen Gummiring 35a ist eine Kupplungshülse 37 abziehbar gehalten, die einem später erläuterten Zweck dient. Es kann schliesslich mit dem oberen Ende des Stockschaftes auch ein Krückengriff 36 gemäss Figur 4 verbunden werden, der eine Bohrung 5˝ und eine Bohrung 7˝ entsprechend den Bohrungen 5 und 7 gemäss Figur 1 aufweist. Als Skistock für alpinen Skilauf weist der Stock mit dem längsgestellten Griff 6 und dem Schneeteller mit Spitze 34 eine Gesamtlänge von beispielsweise 1,32 m auf. Bei Anwendung des Krückengriffes 36 ist der Stockschaft 1,2 entsprechend zu verkürzen. Es kann ein Verlängerungsstück vorgesehen sein, welches zwischen das untere Ende des Rohres 2 und den Schneeteller 33 eingefügt werden kann und das an seinen Enden entsprechende Kupplungsmittel aufweist. Dieses Zwischenstück kann beispielsweise eine Länge von 30 cm aufweisen, um den Skistock für Langlauf auf eine totale Länge von etwa 1,60 m zu bringen.Figures 2 to 5 show, on a somewhat smaller scale than Figure 1, the versatility and ease of use of the stick. As shown in FIGS. 2 and 3, the handle 6 is designed and usable as a combined walking stick handle and ski stick handle. In the position according to Figures 1 and 2, the handle is transverse to the longitudinal axis of the stick and is coupled to the same by means of the holes 5 and 7 according to Figure 1. The handle can be connected in the position of Figure 3 with corresponding holes 5 'and 7' in the direction of the longitudinal axis with the stick shaft. Accordingly, with the lower end of the tube 2, the buffer 8, 9, according to FIG. Fig. 5) are connected to the lower end of the stick shaft. A coupling sleeve 37 is held removably on a rubber ring 35a, which serves a purpose explained later. Finally, a crutch handle 36 according to FIG. 4 can also be connected to the upper end of the stick shaft, which has a bore 5˝ and a bore 7˝ corresponding to the bores 5 and 7 according to FIG. As a ski pole for alpine skiing, the pole with the longitudinal handle 6 and the snow plate with tip 34 has a total length of, for example, 1.32 m. When using the crutch handle 36, the stick shaft 1, 2 must be shortened accordingly. An extension piece can be provided which can be inserted between the lower end of the tube 2 and the snow plate 33 and which has corresponding coupling means at its ends. This intermediate piece can, for example have a length of 30 cm to bring the ski pole for cross-country skiing to a total length of about 1.60 m.

Figur 6 zeigt eine Verwendung eines Stockpaares gemäss der Erfindung als behelfsmässige Lawinensonde. Es werden hierzu zwei als Skistöcke ausgerüstete Stöcke verwendet, von welchen beide Handgriffe 6 entfernt und der eine Schneeteller von der Spitze 34 entfernt wurde. Dann werden die beiden Rohre 1 der Schäfte mittels der Kupplungshülse 37 miteinander verbunden. Diese Kupplungshülse ist ein sehr einfacher Teil, nämlich eine Hülse, in welche die Stockenden spielarm eingeführt werden können und welche zwei Bohrungen 38 zur Aufnahme der Kupplungsknöpfe 4 aufweisen. Diese Lawinensonde erreicht eine Länge von etwa 2,40 m. Sofern verfügbar, könnten auch noch die oben erwähnten Verlängerungsstücke eingesetzt werden, um eine Sondenlänge vonn etwa 3,00 m zu erreichen.FIG. 6 shows the use of a pair of poles according to the invention as a makeshift avalanche probe. Two poles equipped as ski poles are used for this purpose, from which both handles 6 have been removed and one of the snow plates has been removed from the tip 34. Then the two tubes 1 of the shafts are connected to one another by means of the coupling sleeve 37. This coupling sleeve is a very simple part, namely a sleeve into which the stick ends can be inserted with little play and which have two bores 38 for receiving the coupling buttons 4. This avalanche probe has a length of approximately 2.40 m. If available, the extension pieces mentioned above could also be used to achieve a probe length of approximately 3.00 m.
