Description

[0001] The present invention relates to a pick for an ice axe. The invention also relates to an ice axe equipped with such a pick.

[0002] An ice axe typically has a shaft with a point at one end and a pick at the other. Such an ice axe may also be called an ice pick, ice tool, or ice climbing tool. The pick may also be called a hoe. A shovel or hammer may also be attached to the end of the shaft on the side opposite the pick.

[0003] A conventional pick is known, for example, from EP 2 471 581 B1 and has a holding area for attaching the pick to the shaft of the ice axe and a point area that faces away from the holding area in a longitudinal direction of the pick. The pick has an underside that faces the shaft when the pick is attached, and an upper side that faces away from the underside in a vertical direction.

[0004] Other ice axes with picks are known, for example, from DE 84 34 521 U1, from CH 602 284 A5, from AT 341 136 B, from AT 305 520 B and from FR 556 829 A.

[0005] Another hoe is known from EP 0 076 787 A1, which has a base having the underside of the hoe and a blade having a blade edge extending along the top of the hoe and having a blade thickness measured in a transverse direction of the hoe and a blade height measured in the vertical direction of the hoe, extending from the blade edge to a transition edge where the blade transitions into the base, wherein the base has a base thickness measured in the transverse direction of the hoe, wherein the hoe has a hoe height measured in the vertical direction of the hoe, extending from the top of the hoe to the underside of the hoe, wherein the blade thickness outside the transition edge is less than the base thickness, and wherein the blade height decreases along the longitudinal direction of the hoe from the beginning of the blade to the end of the blade.In the well-known hoe, the blade extends in the longitudinal direction over about 25% of the hoe and in the tip area in the vertical direction over about 25% of the hoe.

[0006] Another hoe with a blade is known from DE 10 2016 110 361 A1, in which the blade extends in the longitudinal direction essentially over the entire hoe with a largely constant height, and in the tip area extends in the vertical direction over about 25% of the hoe.

[0007] Ice axes with picks are primarily used in mountaineering, for example in technical ice climbing, extreme mixed climbing, and dry tooling. The ice axe is a hand-held tool whose efficiency depends significantly on the pick. In ice climbing, the climber (male / female / diverse) strikes the ice axe against the ice like an axe. The pick is intended to penetrate the ice to create a secure hold for the climber. Various, sometimes conflicting, requirements are placed on the pick. On the one hand, the pick must possess sufficient stability and strength to safely withstand the forces generated during its proper use. To this end, the pick, or ice axe, must pass rigorous tests in accordance with the European standard EN 13089.High stability and strength can be achieved, for example, by a correspondingly thick ice pick, measured in a transverse direction. Furthermore, the pick should be able to penetrate the ice as deeply as possible to provide the most secure anchor for the climber. For this purpose, the pick is usually designed with a pointed tip. A thinner wall also facilitates penetration into the ice. For secure anchoring, it is also important that the pick, driven into the ice, can bear a large area of ​​contact with the ice on its underside when under tension. Again, a greater wall thickness is necessary for this. Finally, the pick must be easy to pull out of the ice while climbing, for which a thinner wall is advantageous.

[0008] The present invention addresses the problem of providing an improved or at least a different embodiment for an ice pick of the type described above or for an ice axe equipped therewith, which is characterized in particular by easy driving into the ice, easy removal from the ice and a secure hold in the ice with sufficient strength.

[0009] This problem is solved according to the invention by the subject matter of the independent claim. Advantageous embodiments are the subject matter of the dependent claims.

[0010] The invention is based on the general concept of equipping the pick with a blade that extends from the tip over at least 30% of the pick's length. In the blade area, the pick has a thinner wall than outside the blade area. Furthermore, the blade height increases towards the tip. This specific geometry results in a comparatively small cross-sectional area at the tip, perpendicular to the pick's length, which then increases along the blade from the tip. In particular, this makes it relatively easy to drive the pick into the ice. Moreover, the pick can have a comparatively large wall thickness on its underside, which improves its support in the ice and facilitates achieving a secure hold.The reduced wall thickness in the area of ​​the blade facilitates the removal of the pick from the ice. When the climber pulls on the ice axe using a handle positioned at a distance from the pick on the shaft, the support of the pick's underside against the ice causes a rotational movement of the ice axe, driving the pick and blade into the ice. This enlarges the opening created in the ice by the pick, making it easier to pull the pick out.

[0011] Specifically, the invention proposes that the hoe comprises a base comprising the underside of the hoe and a blade. The blade extends from a blade beginning located in the tip region over at least 30% of the hoe's length to a blade end located away from the tip region. The blade has a blade edge running along the top surface of the hoe and possesses a blade thickness measured in the transverse direction of the hoe and a blade height measured in the vertical direction of the hoe. The blade height extends from the blade edge to a transition edge where the blade merges into the base. The base has a base thickness measured in the transverse direction of the hoe. Outside the transition edge, i.e., at a distance from the transition edge in the vertical direction of the hoe, the blade thickness is smaller than the base thickness.The blade height extends at least at the blade tip or in the area where the blade tip is located over at least 50% of the hoe height, thus occupying a significant portion of the hoe height, which reduces the cross-sectional area of ​​the hoe at the blade tip. However, the blade height decreases along the length of the hoe from the blade tip or the area where the blade tip is located to the blade tip. In other words, starting from the tip, the proportion of the blade to the hoe decreases along the length of the hoe, while the proportion of the base to the hoe increases. Consequently, the blade has its greatest absolute and / or proportional height at the blade tip or in the area where the blade tip is located, and this height then decreases towards the blade tip.Furthermore, the blade height, at least outside the blade's starting point (i.e., at least from a distance measured along the length of the hoe from the blade's starting point), is less than the hoe height measured along the hoe's vertical axis, extending from the top to the bottom of the hoe. In other words, the blade does not extend over the entire hoe height, at least outside the area containing the blade's starting point.

[0012] The pick is typically a metal part, especially made of steel or a light metal alloy, particularly a titanium alloy. Ideally, the pick is a flat, straight component defined by a longitudinal direction, a transverse direction, and a vertical direction, all perpendicular to each other. The vertical direction is defined by the direction in which the holding area faces away from the tip area. The vertical direction is defined by the direction in which the underside of the pick faces away from the top surface. The underside of the pick is defined by the fact that, when the pick is mounted on the shaft, it faces the shaft. The transverse direction then determines the pick's wall thickness.

[0013] In this context, the directional terms "front" and "back" refer to the longitudinal direction of the hoe, while "top" and "bottom" refer to the vertical direction. "Forward" then means away from the holding area along the hoe's longitudinal direction, while "backward" means away from the tip area along the hoe's longitudinal direction. "Upward" means away from the underside of the hoe along the vertical direction, while "downward" means away from the top of the hoe along the vertical direction.

[0014] Preferably, the blade extends along the length of the hoe only over a portion of it, not along the entire hoe. Preferably, the blade extends along the length of the hoe over a maximum of 80%, 75%, or 70% of its length. This improves the stability of the hoe.

[0015] According to an advantageous embodiment, the blade can extend from its beginning over at least 40%, and in particular over at least 50%, of the hoe in the longitudinal direction of the hoe to the end of the blade. This design enhances the advantages described above.

[0016] In advantageous embodiments, the blade height extends at least at the blade's beginning over at least 60%, preferably over at least 70%, 75%, 80%, or 90% of the pick's height. A particularly advantageous embodiment is one in which the blade height extends at least at the blade's beginning from the top of the pick to the bottom, i.e., over 100% of the pick's height. This means that there is no base at least at the blade's beginning, so the blade extends over the entire pick's height. This facilitates driving the pick into the ice.

[0017] According to the invention, the blade height decreases continuously, i.e., steplessly, along the longitudinal direction of the pick from the beginning to the end of the blade. This continuous contour of the blade facilitates penetration into the ice.

[0018] According to another advantageous embodiment, the base can have a base height measured in the direction of the hoe's height, extending from the transition edge to the underside of the hoe. According to another advantageous embodiment, the base height can increase along the longitudinal direction of the hoe from the beginning of the blade to the end of the blade, with a continuous increase in base height being preferred. This measure increases the stability and strength of the hoe.

[0019] According to the invention, the pick has a point that tapers forward, with the point transitioning directly into the blade at the rear. This design of the pick in the tip area improves its penetration into the ice. Optionally, the point can be designed to project downwards beyond the underside of the pick.

[0020] According to an advantageous embodiment, the blade thickness can increase continuously in the vertical direction of the pick, from the blade edge to the transition edge. This makes the pick blade act like a knife blade. In particular, this simplifies pulling the pick out of the ice. The blade can have two sides facing away from each other in the transverse direction of the pick and having a straight profile or an outwardly concave or convex profile perpendicular to the longitudinal direction of the pick. Straight blade profiles result in a conical blade. Outwardly concave blade profiles result in a blade with a hollow groove. While the conical blade is equally inexpensive to manufacture, the blade with a hollow groove offers better cutting performance and thus makes it easier to remove the pick from the ice.

[0021] In another embodiment, the blade thickness can be constant in the vertical direction of the pick, from the blade edge to the transition edge, with the transition edge then being designed as a step. In this case, particularly small cross-sectional areas result in the blade area perpendicular to the pick's longitudinal direction, which facilitates the pick driving into the ice.

[0022] The blade edge running along the top surface of the pick can be blunt or sharp. Additionally or alternatively, the blade edge can be flat or pointed perpendicular to the pick's length, i.e., it can have a flat or pointed profile. The blunt blade edge with a flat cross-sectional profile can improve the pick's strength, while the sharp blade edge with a pointed cross-sectional profile facilitates driving the pick into and pulling it out of the ice. Furthermore, it can optionally be provided that the blade edge varies in sharpness or bluntness along the pick's length. Preferably, the sharpness can decrease or the bluntness can increase along the pick's length from the beginning to the end. In particular, the blade edge can transition sharply into a pointed tip at the beginning and bluntly into the base at the end.

[0023] According to another embodiment, the blade edge can have a continuous profile along the longitudinal direction of the pick from the beginning to the end of the blade. This measure facilitates the pick driving into the ice.

[0024] In another embodiment, the blade edge can transition smoothly into the top surface of the hoe at the blade end. This avoids a step at the transition between the blade edge and the top surface of the hoe at the blade end, which also facilitates the driving of the hoe.

[0025] According to another embodiment, the pick can have sawtooth-like projections on its underside, i.e., at its base, which extend downwards from the underside of the pick. In particular, these projections can be barbed or inclined in such a way as to facilitate the pick's penetration into the ice while hindering its slippage out of the ice when its underside is in contact with the ice. Thus, these projections improve the creation of a secure anchor point.

[0026] An ice axe according to the invention has a shaft and a pick of the type described above, which is attached to a head end of the shaft.

[0027] According to an advantageous embodiment, the shaft can have a pick holder at its head end, wherein the pick, with its holding area, is interchangeably attached to the shaft via this pick holder. The interchangeability of the pick allows an old or worn pick to be replaced with a new one.

[0028] Further important features and advantages of the invention will become apparent from the dependent claims, the drawings and the associated description of the figures based on the drawings.

[0029] It is understood that the features mentioned above and those to be explained below can be used not only in the combinations specified, but also in other combinations or individually, without departing from the scope of the invention as defined by the claims. Components of a higher-level unit, such as a device, apparatus, or arrangement, mentioned above and those to be mentioned below, which are designated separately, can form separate parts or components of this unit or be integral areas or sections of this unit, even if this is depicted differently in the drawings.

[0030] Preferred embodiments of the invention are shown in the drawings and are explained in more detail in the following description, wherein identical reference numerals refer to identical or similar or functionally identical components.

[0031] They show, schematically, Fig. 1 a side view of a hoe, Fig. 2 enlarged cross-sections of the hoe corresponding to section lines II in Fig. 1 in two different embodiments A, B, Fig. 3 enlarged cross-sections of the hoe corresponding to section lines III in Fig. 1 in the two embodiments A, B, Fig. 4 top views of the hoe corresponding to a viewing direction IV in Fig. 1 in the two embodiments A, B, Fig. 5 A side view of an ice pick with such a pick.

[0032] According to Fig. An ice axe 1 comprises a shaft 2 with a head 3 and a foot 4, which is spaced apart from the head 3. The ice axe 1 also has a pick 5, which is attached to the head 3 of the shaft 2. Advantageously, the shaft 2 has a pick holder 6 at the head 3, by means of which the pick 5 is attached to the shaft 2. For this purpose, the pick 5 can have a retaining area 7, which interacts with the pick holder 6 to attach the pick 5 to the shaft 2. In particular, it can be provided that the pick 5 is attached to the shaft 2 via the pick holder 6 in a way that is interchangeable or detachable. A handle 8 can be formed at the foot 4 of the shaft 2, which simplifies the handling of the ice axe 1 when climbing. The shaft 2 can also be equipped with a point 9 at the foot 4. Furthermore, the shaft 2 can have another tool 10 at the head end 3, which in the example of the Fig. Tool 5 is designed as a hammer or hammerhead. Similarly, tool 10 can be designed as a shovel. In the example of the Fig. The tool 10 is also attached to the pick holder 6, in particular in a replaceable or removable manner. The tool 10 is located on the side of the shaft 2 facing away from the pick 5.

[0033] According to the Fig. 1, Fig. 4 and Fig. The pick 5 has a holding area 7 and a tip area 11, which is directed away from the holding area 7 in a longitudinal direction X of the pick. The pick 5 has an underside 12, which according to Fig. 5, when the pick 5 is attached to the shaft 2, faces the shaft 2. Furthermore, the pick 5 has an upper surface 13 which faces away from the lower surface 12 in a height direction Z. The height direction Z is perpendicular to the length direction X. The pick 5 also has a transverse direction Y, which runs perpendicular to the length direction X and perpendicular to the height direction Z, and which is located in the Fig. 1 and Fig. 5 is perpendicular to the drawing plane.

[0034] According to the Fig. The hoe 5 has a base 14 and a blade 15, as shown in sections 1 to 4. The underside of the hoe 12 is formed at the base 14. The base 14 extends from the tip area 11 to the holding area 7.

[0035] The blade 15 extends from a blade start 16 located in the tip region 11, over at least 30% of the hoe 5 in the hoe's longitudinal direction X to a blade end 17 located away from the tip region 11. The blade 15 has a blade edge 18 that extends along the top surface 13 of the hoe. The blade 15 also has a Fig. 2 and Fig. The blade thickness 19 is recorded and measured in the transverse direction Y of the hoe. Furthermore, the blade 15 has a blade height 20, measured in the height direction Z of the hoe, extending from the blade edge 19 to a transition edge 21. At this transition edge 21, the blade 15 transitions into the base 14. The base 14 has a base thickness 22, also measured in the transverse direction Y of the hoe. The blade thickness 19 outside the transition edge 21, i.e., at a distance from the transition edge 21 in the height direction Z of the hoe, is always less than the base thickness 22.

[0036] The pick 5 has a pick height 23 measured in the pick height direction Z, extending from the pick top 13 to the pick bottom 12. The blade 15 is configured such that the blade height 20 extends at least at the blade start 16, or in a blade start area 29 containing the blade start 16, over at least 50%, preferably over at least 60%, or at least 70%, or at least 75%, or at least 80%, or at least 90%, or even over 100% of the pick height 23. The blade start area 29 is in the Fig. 1 and Fig. 4, each indicated by a curly bracket. The blade height 20 can also be configured such that, at least outside the blade start 16, i.e., at a distance X from the blade start 16 along the longitudinal direction X, it is always smaller than the blade height 23. Furthermore, the blade 15 is configured such that the blade height 20 decreases along the longitudinal direction X from the blade start 16 to the blade end 17. In the embodiments shown here, the blade height 20 at the blade start 16 extends over 100% of the blade height 23 and then decreases continuously towards the blade end 17. It is also conceivable that the blade height 20 is initially constant in the blade start region 29, e.g., at least 80%, at least 90%, or at 100% of the blade height 23, and only then decreases continuously.

[0037] The blade 15 extends in the longitudinal direction X only over a portion of the hoe 5, for example, only up to the holding area 7. In particular, the blade 15 extends over a maximum of 80% and preferably over a maximum of 75% of the hoe 5. However, the blade 15 extends in the longitudinal direction X over a substantial portion of the hoe 5, namely over at least 30%, preferably over at least 40%, and in particular over at least 50% of the hoe 5. In the example of the Fig. 1 and Fig. 4 the blade 15 extends over approximately 60% of the hoe 5 in the hoe's longitudinal direction X.

[0038] According to Fig. 1. The blade height 20 at the blade beginning 16 extends from the upper surface 13 to the lower surface 12, so that there is no base 14 there. Accordingly, in the sectional views of the Fig. 2A and Fig. 2B, base 14 is practically non-existent. How does this work? Fig. As can be seen from Figure 1, the blade height 20 decreases in the longitudinal direction X of the pick from the blade start 16 to the blade end 17, preferably continuously. The base 14 has a base height 24 measured in the pick height direction Z, which extends from the transition edge 21 to the underside 12 of the pick. The base height 24 increases along the longitudinal direction X of the pick from the blade start 16 to the blade end 17, preferably continuously.

[0039] The hoe 5 has a hoe point 25 at its tip 11, which tapers towards the front and transitions directly into the blade 15 at the rear. As it appears Fig. As can be seen from 1, the hoe tip 25 protrudes downwards over the hoe underside 12.

[0040] According to a first embodiment, which is described in the Fig. 2A, Fig. 3A and Fig. As shown in Figure 4A, the blade thickness 19 increases continuously in the hoe height direction Z from the blade edge 18 to the transition edge 21. In contrast, the Fig. 2B, Fig. 3B and Fig. 4B a second embodiment in which the blade thickness 19 is constant in the hoe height direction Z from the blade edge 18 to the transition edge 21. In this case, the transition edge 21 is designed as a step.

[0041] According to the Fig. 2 and Fig. 3 The blade 15 has two blade sides 26 which face away from each other in the transverse direction Y of the hoe. According to the Fig. 2A and Fig. 3A The two blade sides 26 have a profile in the cross-section extending transversely to the hoe's longitudinal direction X, which is convexly curved outwards. In another embodiment not shown, the profile of the blade sides 26 can be concavely curved outwards or straight, with the two blade sides 26 being inclined towards each other. In contrast, in the second embodiment according to the Fig. 2B and Fig. 3B the two blade sides 26 in the profile of the cross-section are straight and run parallel to each other.

[0042] The blade edge 18 can be blunt or sharp, or flat or pointed perpendicular to the hoe's longitudinal direction X. In the case of the Fig. 2A and Fig. In the first embodiment recognizable in Figures 3A and 4A, the blade edge 18 is configured such that it becomes increasingly sharper or more pointed towards the blade start 16, while it becomes increasingly blunter or flatter towards the blade end 17. In the embodiment shown in the Fig. 2B, Fig. 3B and Fig. In the embodiment shown in 4B, the blade edge 18 is flattened, i.e., it is designed to be blunt throughout.

[0043] During the Fig. 2B, Fig. 3B and Fig. In the second embodiment shown in 4 B, it can also be provided that the blade thickness 19, which is constant in the hoe height direction Z, increases in the hoe longitudinal direction X from the blade beginning 16 to the blade end 17, in particular continuously.

[0044] The blade edge 18 can be according to Fig. 1 at the blade end 17 continuously transitions into the upper surface of the hoe 13.

[0045] According to the Fig. 1 and Fig. The pick 5 can have sawtooth-like projections 27 on the underside 12, i.e., at the base 14, which project downwards from the underside 12. The projections 27 are inclined towards the holding area 7, i.e., backwards, thus giving them a barb-like appearance. The projections 27 are also visible in the cross-sections of the Fig. 3A and Fig. 3B recognizable, while in the cross-sections of the Fig. 2A and Fig. 2B are not recognizable. However, this is evident in the cross-sections of the Fig. 2A and Fig. 2B the hoe tip 25 is recognizable, which protrudes downwards over the underside of the hoe 12.

[0046] The pick 5 has at least one through-opening 28 in the base 5 or in the holding area 7, which cooperates to fasten the pick 5 to the pick holder 6 of the ice axe 1.
