Description

TECHNICAL AREA

The present invention relates to a stick plate for a stick, in particular for a ski pole, ski touring stick and / or trekking pole, which has a stocking for receiving a pole and which in particular adapts to different slopes and is preferably individually adjustable in size to different conditions of use.

STATE OF THE ART

The task of a stick plate is generally to ensure a controlled and deep-limited insertion of the stick in the pad / the ground / the snow layer when a pad from the pad The height of the fixed axially on the floor stick plate determines the insertion depth.

Plastics such as PE, PC, but also rubber or vinyl chloride (such as in DE 2 042 134 shown) used.

An older embodiment has a metal ring which is formed by means of radial spokes of flexible material, e.g. Leather was attached to a cuff surrounding the cane, giving the stick plate flexibility in terms of obtaining the underlay and in terms of placing the plane of the stick relative to the cane axis.

There are several approaches in the art for improving stick dishes. The US 4,221,392 describes an asymmetric Skistockteller, by attachment of various peripheral, at the rear end of the plate on these widening parts the base plate and thus by changing the disc surface to different snow conditions is customizable.

The patent US 4,669,752 underlying invention shows a mechanism which makes it possible to attach interchangeable plates of different sizes also at different axial positions along the ski pole.

The US 4,385,776 represents a structure on the ski pole, which also makes it possible to easily attach detachable plates of different sizes via a snap mechanism.

The US 4,336,949 also mentions the possibility of attaching replaceable plates of various sizes to the ski pole. Here are a particular set angle between the ski rack and ski pole, an elastic torsion and the asymmetry of the plate is the core of the invention.

The DE1185098 mentions a stick plate for a stick, with a stocking for receiving a stick tube, wherein the plate portion is formed as a substantially rigid disc and is freely rotatable about a pole axis by a ball joint and tiltable about an angle range of 150 degrees about a tilt axis.

A disadvantage of stick plates made of inflexible material is that the stick plate can not adapt to a slope of the ground (for example, slope on ski tours). For stick plates made of flexible, e.g. thermoplastic material, which would have this possibility, but on the other hand results in the disadvantage that they are as good as completely stiff at low temperatures, as they prevail in ski resorts, when they are exposed to the cold for a long time. Furthermore, especially the targeted flexibly trained areas are brittle and usually brittle. On the other hand, the force can not be optimally transferred to the pad when using the stick when a stick plate is made of such a soft material. The repulsion force is also reduced and the contact via the floor with the floor uncontrolled if the floor is not placed at right angles to the surface of the substrate and plugged.

PRESENTATION OF THE INVENTION

The invention is therefore inter alia the object of remedy the disadvantages arising from the prior art and to develop an improved stock plate, in particular to various slope slopes and preferably additionally adaptable to different snow conditions. These two features are especially important for ski touring, but can also be useful for trekking or the like.

The solution to this problem is achieved, inter alia, that a stick plate is provided for a stock with stocking for receiving a stick tube available. The stick plate according to this invention is characterized, inter alia, by the following features: The stick plate has a plate portion which is considered to be substantially rigid, i. formed in inflexible, rigid disc and which by a hinge about the longitudinal axis of the stick freely rotatable (rotatable) and over an angular range of normally 150 degrees about a tilt axis or tilt axis, which is substantially perpendicular to the pole axis, tiltably mounted. The per se rigid plate is thus rotatable about two axes, about a first axis, which is arranged substantially along the pole axis, being given about this first axis a free rotation. Furthermore, the stick plate is tiltably mounted about a second axis in order to be able to adapt, for example, said slope slope. The specified angle range can also be greater in the case of the second axis, if the fecal position or the joint altogether permits a larger area. The core of the invention thus consists, in particular, of forming the plate in rigid material, but not rigidly fixing this rigid plate but, by means of a joint or movable connecting element, substantially flexibly about two axes on the ski pole and thus the flexibility with respect to the slope not by a flexible material, but to achieve by a hinged connection of the dish washer with the ski pole.

In addition, the joint has two opposing axially offset joint collars on the socket, as well as two arranged on the inner plate, opposite, circular joint discs, at least one of the two joint collars has an open in the direction of the opposite joint collar circumferential annular groove. The joint discs can be integrally formed with the inner plate, and equally may preferably at least one of the joint collars be formed integrally with the stocking. The two opposing joint disks preferably each extend essentially in half on both sides of the plate plane defined by the plate region and substantially at right angles to the latter. The plate plane is defined as being substantially parallel to the rigid disk.

The two flexible discs are formed opposite each other in parallel planes with the above-mentioned hinge opening between the two flexible discs, and preferably such that the two axes of symmetry of the flexible discs are collinear (normally substantially perpendicular to the first axis), and that the Symmetry axis of the first axis and the joint opening intersects with this axis of symmetry in order to ensure the smoothest possible movement around both axes. The rigid inner plate halves the joint discs in their midst, so to speak, so that the plate plane substantially perpendicular protruding part-circular surfaces of the joint discs are cut to the thickness of the inner plate in the joint discs in a sense and the Gelenkscheibenhälften extending on both sides of the plate plane in the Basically, circle segments are.

Essential in this context is, among other things, that this mobility is given around the two axes by a joint. Under a joint in the context of the present invention, a component or element is to be understood, which provides the mobility around the two said axes, the mobility around both axes is ensured in each case without material connection between the elements connected by the joint, ie the Joint does not have flexible areas that provide mobility (for example, in the Meaning of a film hinge), but it has individual elements which slide against each other, roll against each other, or roll, essentially without being deformed.

The advantage of this invention is, inter alia, that the stick plate, despite its intrinsically rigid properties and its consequent robustness, and thus the stick itself, is adaptable to different slope slopes. This allows for improved power transfer to the stick when repelled. Due to this flexibility and the associated movement of the stock plate on the floor, it is also achieved at the same time that any snow that may be lying on the stock plate is continuously shaken off. Thermoplastic material or combinations of metals, different plastics, fiber-reinforced plastics, fiber composites, etc. may be used to form the stock disc, for example materials such as polyamides, PE, PP, PVC, PC.

A first preferred embodiment is characterized in that a mobility of the stick plate relative to the axis of the pole and / or the tilt axis is ensured by itself rigid elements by the rigid elements are arranged in and / or sliding against each other and / or rolling. In other words, the joint has areas, or elements, which provide mobility around the two axes by sliding or rolling the elements together.

The stocking mounted on stocking tube engages preferably in a arranged in the inner plate hinge opening, so that the inner plate is rotatably mounted relative to the stick axis about the (with the pole tube rotatably connected) Stockfassung. In other words, this joint opening, in which engages the Sucking, provides the rotation about the first axis available.

According to a further preferred embodiment of the invention, the joint opening is an opening of preferably ellipsoidal, but possibly also oval, polygonal or rectangular shape, optionally with rounded corners. This elongated configuration is advantageous for allowing tilting about the second axis. In particular, the oval or ellipsoidal shape is preferred, since at full Unloading the inclination, the preferred way round or cylindrically shaped outer surface of the faketaking optimally comes to rest on the edge of the opening.

It is particularly advantageous if the diameter of the joint discs is insignificantly smaller, preferably at most 0.1-3 mm, preferably 0.2-1.5 mm, smaller than the axial distance of the two joint collars from each other at the recess. Of the axial distance of the joint collars is defined as the distance between the bottom (or the most essential deepest region) of the open annular groove and the surface of the opposite sleeve facing this Ringnutboden. If both sleeves have ring grooves or both have a bottom, then the axial distance between the joint collars means that between the two mutually axially opposite annular groove bottoms.

A preferred embodiment is characterized in that at least those halves of the two joint discs, which face an open annular groove, engage in the annular groove, and that in particular when at least those halves of the two joint discs, which are facing the annular groove, starting from the plate plane, have a width , which is slightly smaller, preferably not more than 0.1- 3 mm, preferably from 0.2 to 1.5 mm smaller than the width or existing width of the annular groove.

The annular groove may have different shapes, so it may be a polygonal or round U-shaped or even a V-shaped groove, and accordingly, the peripheral edge of the joint discs is preferably then provided with a corresponding shape to the friction to keep as low as possible while gliding. Preferably, the annular groove is bounded on at least one side by a comb which is round or angular, and the difference between the width of the joint discs is only so much smaller than the width of the annular groove, that the flexible disc just between the comb and the tube shell the stocking can intervene in the annular groove.

A further preferred embodiment of the stick plate has an inner plate of rigid material, on the outer plate rings different outer diameter can be placed and are preferably releasably fastened to the inner plate. These Aussentellerringe are preferably as rigid as the inner plate, preferably made of the same material. It is conceivable to design the inner plate in a different color than the Aussentelleringe, and it is also possible to design the Aussentellerringe for different sizes with different colors and / or patterns. The interchangeability of Aussentellerrings would be Basically, even without the combination with the above-described joint conceivable. The Aussentellerring can be secured by means of various possible preferred simple and robust Einrastmechanismen with the inner plate, and is released by a preferably simple and robust Ausrastmechanismus again from the inner plate.

In particular, it is possible to provide a construction that the Aussentellerring can be placed in the axial direction along the axis of the pole on the inner plate and that by a rotational movement in the plate plane about the pole axis the Aussentellerring on the inner plate can be fastened. This rotational movement may be in an angular range of preferably about 3-30 degrees depending on e.g. on the length and / or width and the number of corresponding tongues or other guide respectively latching means. Such a plug-and-turn fastening mechanism, also referred to as a bayonet lock, is known from other technical fields, and may in addition be e.g. have a catch, so that the shutter can be opened again only after releasing this catch.

Alternatively or additionally, it is possible in other words, self-locking the Aussentellerring on the inner plate fastened design.

In addition, it is advantageous if the Aussentellerring has a toothing in the edge region on its underside. This toothing allows a better traction of the plate on the surface.

In a further embodiment, the outer plate ring for locking on at least one engaging element, preferably a pin, which engages in a recess in the inner plate, in particular at the periphery or vice versa, since it is also conceivable that engaging the inner plate engage in recesses of the outer plate ring. The engaging element is preferably at right angles to the plate plane defined by the plate area. Alternatively, it is also possible to align the engaging element and correspondingly the corresponding recesses in a radial direction.

In this embodiment, it proves to be advantageous if the pin has a head whose diameter is greater than the diameter of the pin body, in particular if the peripheral recesses on the inner plate or outer plate have a hole with a diameter which is insignificantly larger than the diameter of the pin head, and if this hole in the circumferential direction of the plate area merges into a slot whose width is smaller than the diameter of the pin head, but insignificantly larger than the diameter of the pen body.

It may be advantageous for a further preferred embodiment if the inner plate and / or the outer plate ring has radial spokes substantially in the plate plane, so that if both the inner plate and the outer plate ring have radial spokes, the radial spokes in the outer plate ring to some extent an extension represent the spokes of the inner plate, especially if at least one spoke has at least one guide and a locking device, which is the same after placement of the outer plate ring for locking the same along the guide displaced. The Aussentellerring can be fixed after placement, for example, by a locking of the locking element or by a rotational movement thereof on the inner plate ring, so that the outer plate ring is no longer rotatable relative to the inner plate.

It also proves to be advantageous if the inner plate has at its periphery a groove from which at least one side of inner plate tongues is formed, and that Aussentellerringzungen pushed into the groove and can be latched by a rotational movement. A functionally similar mechanism is of course also given when the outer plate has at its periphery such a groove into which inner plate tongues are pushed and latched by a rotational movement.

Preferably, the tilt axis is substantially perpendicular to the pole axis. The pan area is typically tiltably mounted about the tilt axis over an angular range of about 100-150 degrees. Theoretically, the maximum tilt angle could be up to 180 degrees, but the technical design, the shape and the material of the joint elements, in particular the joint sleeves and the annular grooves, limit this angle. Effectively adapts the stick plate up to a slope of typically a maximum of about 40 - 60 degrees to this. The angle range in which the Stick plate can tilt around the tilt axis is thus about 100 degrees. In maximum tilt position, the joint cuffs normally contact both the articular discs and the plate plane.

In a particularly preferred embodiment, the above-mentioned stick plate is a ski stick, in particular a tour plate.

• Ein Dreh- /Kippmechanismus kann auch durch eine Vorrichtung erreicht werden, die im Wesentlichen aus einer das Stockrohr umfassenden um die Stockachse frei drehbaren oder aber alternativ auch damit fest verbundenen, in axialer Richtung aber unbeweglichen Kugel besteht, welche von einer am Stockteller befestigten Fassungsmanschette dadurch ,eingeklemmt' wird, dass die Fassungsmanschette an der die Kugel umgreifenden Oberfläche im Wesentlichen denselben Radius aufweist wie die Kugel selber. Der Stockteller ist dadurch somit sowohl frei drehbar um die Stockachse, als auch relativ zur Tiltachse in einem Winkelbereich von ca. 150 Grad, effektiv ca. 100 Grad frei kippbar. Dies ermöglicht bei eingestecktem Stock eine gewissermassen konische Drehbewegung des Stockes um 360 Grad.

Further possible embodiments within the meaning of the present invention are the following:

• A turning / tilting mechanism can also be achieved by a device consisting essentially of a pole surrounding the pole freely rotatable or alternatively also firmly connected thereto, but immovable in the axial direction ball, which is characterized by a mounted on the stock cup socket collar 'clamped' is that the socket cuff on the surface encompassing the ball has substantially the same radius as the ball itself. The stick plate is thus thus both freely rotatable about the pole axis, as well as relative to the tilt axis in an angular range of about 150 degrees, effectively tilted freely about 100 degrees. This enables a somewhat conical rotary movement of the stick by 360 degrees when the stick is inserted.

There are also other locking mechanisms for the Aussentellerring possible. Thus, for example, the rotatability can be given by a freely rotatable about the pole tube but axially fixed Dekassung has at least two flanges / engaging elements on which an inner plate with corresponding recesses tiltable can be placed. Similarly, it is possible to provide a freely rotatable about the pole tube, but axially fixed pigeonhole, on which is addressed via two opposite and collinear axes of the plate.

WAYS FOR CARRYING OUT THE INVENTION

In Figures 1a-1i and Figures 2 and 3 a stick plate according to a first embodiment is shown. This embodiment includes a stick plate 1, which has a substantially circular inner plate 2, and a substantially annular outer ring 3 mounted thereon, wherein the inner diameter of the outer plate ring 3, which forms the positive connection, is substantially the same size as the outer radius of the inner plate. 2 Both the inner plate 2 and the outer plate ring 3 could also be shaped in a shape deviating from the circular shape, for example star-shaped or even asymmetrical, the inner edge of the outer plate ring 3 ideally being adapted to the shape of the outer edge of the inner plate 2.

The stock plate 1 consists of a hinge portion 4 and a plate portion 2,3. The plate region has an inner plate 2 with a joint opening 17 flanked by circular jointed disks 15. Through this joint opening 17 a stocking 5 with joint collars 6 for receiving a pole tube (not shown in the figures) is inserted through the opening 7. Radial spokes 9 are preferably substantially star-shaped arranged in the plane defined by the plate area 2.3 plate plane, but may also differ from this arrangement. The spokes 9 can extend radially to the annular edge 14 of the outer plate ring 3, such as in FIGS. 1a . c . dg , and FIG. 3 shown.

The movability / tiltability of the stick plate relative to the stocking tube 5 attached to the stocking 5 is essentially limited by the joint discs 15 and by the shape and diameter of the joint opening 17. The two in parallel planes opposite and coaxial joint discs 15 are, as in the Figures 1c-f are particularly well visible, formed substantially perpendicular to the plane defined by the plate area 2, 3 and the plate area 2, 3 substantially parallel plate plane and expand each half on both sides of the plate plane, as in Figures 1c-f and 1h and 1i seen.

When tilting the stick plate 1, the joint discs 15 slip with their circular arc / circumference along the joint collars 6 on the stocking 5, wherein at least those two circular segments of the joint discs 15, which are on the side extend the plate plane on which the joint sleeve 6 is fixed to the opposite joint sleeve 6 facing open annular groove 8, engage in the annular groove 8. Here, the joint discs 15 are always positioned in the annular groove 8 of the joint sleeve 6. The flexible discs 15 are preferably formed as radially outwardly concave shaped spherical sectors, which contributes to an increased stability of the joint discs 15 and thus of the joint 4.

The inner surfaces of the joint discs 15 are the stocking 5 loosely at a small distance and the inner plate 2 is thus freely rotatable about the pole axis A and 5 on the stocking. Thus, the stock plate 1 is at the stocking 5 at the same time freely rotatable both about the stick axis A and tiltable about a Tiltachse B, which is substantially perpendicular to the floor axis A.

Recesses 16 for weight reduction are, such as in Fig. 1a possible both on the inner plate 2 and on the outer plate ring 3. Even the joint collars 6 may have material recesses for weight reduction (shown in FIG FIGS. 1a-g , and FIG. 2 ), as well as the joint discs 15 (visible in FIGS. 1a , cf, and FIG. 2 ).

Out FIG. 1h It can be seen that the Staccination 5 is formed with a fixed (upper) joint sleeve 6 in one piece, while the inner plate 2, optionally with attached outer ring 3, but in any case with the attached to the inner plate 2 joint discs 15 represent a separate part, which during manufacture or assembly is placed on the freestanding lower end of the stocking 5 (without joint sleeve) in the axial direction. The second joint sleeve 6 is then also placed on the free-standing end for mounting, the stocking 5 having at the free end a structure that allows the joint sleeve 6 to be screwed or snapped onto the stocking 5 (toothing, thread). According to Figure 1d For example, the joint collar 6 which is placed on top during assembly has a slot 33 which permits a clamping action of the joint sleeve 6 and facilitates assembly.

From the cross section in FIG. 1h In addition, it can be seen that a structure is provided on the underside of the floor plate 1, in which the locking element 12 in Radial direction to the ring edge 14 can be latched.

The first preferred embodiment of the invention according to the Figures 1a-1i and Figures 2 and 3 has an inner plate 2 of rigid material with radial spokes 9 in the plane defined by the plate area 2.3 plate plane. The annular outer ring 3 also has spokes 9, which represent an extension of the spokes 9 of the inner plate 2 in the mounted state. The guide 11 of the inner plate 2 is thus extended by placing the Aussentellerringes 3 also radially outward. At least one of the spokes 9 has a locking device 12, which is displaced after placement of the outer plate ring 3 for fixing the same along the guide 11. This locking device 12 is in Figure 1c viewed in cross-section from the edge of the outer plate ring 3 and in FIG. 1h viewed from the side. For placing the Aussentellerringes 3 this is applied concentrically to the inner plate 2 from the axial direction and rotated until the Aussentellerringzungen 18 (shown in FIG FIG. 3 ) above and below the inner plate tongues 20 (shown in FIG FIG. 2 ) come to rest. Subsequently, the rotational position of the outer plate ring 3 is fixed by the locking device 12 is actuated radially towards the rim 14. The Aussentellerring 3 is thus prevented from rotating relative to the inner plate 2. In order to remove the outer disc ring 3, the locking device 12 is actuated radially inwards in the direction of the joint 4 and then rotates the outer disc ring 3 on the inner plate 2 about the pole axis A counterclockwise, if the clockwise engagement took place, or vice versa the Aussentellerringzungen 18 and the inner plate tongues 20 are no longer engaged. The in Fig. 3 shown Aussentellerring 3 has on its underside a flat edge region. However, it is possible that the Aussentellerring 3 has a toothed edge region on its underside, with the teeth facing down to allow better traction.

FIG. 4a shows according to a second embodiment of the invention, an outer disc ring 3, which has engaging elements whose shape in FIG. 4b is shown schematically. The engaging elements are according to this Embodiment designed as pins 22. A pin 22 is defined for this embodiment as having a pin head 29 and a pin body 30. The engaging elements could, however, in another embodiment also have a different (functionally identical) shape.

Figure 4c shows according to the same embodiment of the invention as in FIGS. 4a and 4b an inner plate 2 of rigid material having recesses 23 on its periphery, through which the pins 22 of the outer plate ring 3 can engage and can be engaged by a small rotational movement in an angular range of about 3 to 30 degrees about the axis of the pole.

In FIG. 4d is a recess 23 of Figure 4c once again shown individually. It has in this embodiment, a hole 24 with a diameter d2, which is slightly larger than the diameter d3 of in FIG. 4b schematically illustrated engaging element, which according to this embodiment, a pin 22 (according to this embodiment, a pin head 29 and a pin body 30 having) on the outer plate ring 3, but only so much larger that a pin head 29 just fits through the hole 24. This hole 24 passes into a slot 25 whose width b3 is insignificantly smaller than the diameter d3 of the pin head 29 on the outer plate ring 3. If a plurality of elongated holes 25 arranged in the circumferential direction in the periphery of the inner plate 2, it is necessary that all slots 25 have the same orientation in the circumferential direction. The slot 25 may alternatively be formed from a transition into a hole 24 rectangle. The elongated holes can also have a curved course, which follows the circulation around the pole axis.

FIGS. 5a-f show various possible embodiments of an annular groove 8 on a joint sleeve 6. The annular groove 8 is preferably limited on at least one side by a comb 27 which may be round or square. The flexible discs 15, which engage in the open annular groove 8 are preferably substantially corresponding to the annular groove 8, ideally adapted to the shape of the annular groove 8, augebildet so that they can engage in the annular groove 8 as possible frictionless and yet well-guided. That is, when the annular groove 8 is V-shaped, as an embodiment in FIG Fig. 5b shows, the flexible disc 15 is at its periphery also V-shaped, but complementary to the annular groove 8. If the annular groove 8 an angular, substantially perpendicular to the floor axis A protruding bottom 26, then the flexible disc 15 is ideally also square or possibly rounded. The annular groove 8 may also be limited on at least one side, preferably on the radially outer side by a comb 27, wherein the connection between the bottom 26 and the comb 27 does not necessarily have to be formed at right angles. The corners of the Ringnutbodens 26 may also be rounded, as also in Fig. 5 shown schematically.

In FIG. 6 a further embodiment is shown comprising a ball comprising the pole tube to which a stick plate is clamped by means of a socket collar. The ball is freely rotatable about the pole axis or, alternatively, also firmly connected thereto, but immovably mounted in the axial direction. The mounting collar fastened to the pole plate can thereby 'pinch' the ball so that the collar on the surface encompassing the ball has substantially the same radius as the ball itself. The stick plate is thus both freely rotatable about the pole axis, as well as relative to the tilt axis in an angular range of about 150 degrees, effectively tilted freely about 100 degrees. This enables a somewhat conical rotary movement of the stick by 360 degrees when the stick is inserted.
