Definitions
- the present invention relates to a snow basket comprising a connecting portion by which the snow basket is connected or connectable with the main body of a pole, and a snow catching portion which extends out from the connecting portion and comprises an outer delimiting edge.
- the invention furthermore relates to a sports pole which comprises such a snow basket.
- Poles with snow baskets are part of the equipment for hikers, mountain climbers, touring skiers, mountaineers or the like and, on the one hand, allow the arms' muscle power to provide assistance when moving up the mountain and, on the other hand, offer security and grip by keeping the body balanced when climbing up or down or when setting off.
- the pole is held by the user in a grip zone and planted on the ground with a pole tip zone.
- a snow catching portion of known snow baskets generally has a plate- or dome-shaped contour and, to reduce weight, may comprise one or more orifices or also have a mesh-like structure.
- the snow catching portion comes to a rest on the snow and prevents the pole from sinking too deep.
- the snow is compressed under the snow basket and pressed against the snow catching portion, such that snow often remains stuck to the snow catching portion.
- the quantity of adhering snow may increase further until finally a large lump of snow is sticking to the snow catching portion and has to be laboriously removed by the user because it markedly increases the weight of the pole which has to be moved.
- the object of the invention is therefore to provide a snow basket for a pole, in particular a touring ski pole, which reduces the problem of snow sticking to the snow basket, such that less effort is required to clean the snow basket during use.
- Another object of the invention is to provide a sports pole with such a snow basket which permits use with the fewest possible interruptions for cleaning the snow basket.
- the present invention provides a snow basket comprising a connecting portion, to which the snow basket is connected or connectable with a main body of a pole, and a snow catching portion, which extends out from the connecting portion and comprises an outer delimiting edge, wherein the snow catching portion comprises a slot which reaches from the outer delimiting edge to an inner portion of the snow catching portion and is open at the outer delimiting edge.
- the essential feature of the invention is thus a slot which is formed in the snow catching portion and reaches to the outer delimiting edge. It has been found that, thanks to such a slot, the mechanical stability of the snow basket for performing its supporting function can be retained, while markedly less snow sticks to the snow catching portion than in the case of a conventional snow basket which does not comprise such a slot. This result was not in any way to have been expected and was surprisingly identified in the course of testing by the inventor.
- One possible explanation for the reduced tendency of snow to stick may be that the slot modifies the deformation behaviour of the snow catching portion in such a manner that different subportions of the snow catching portion are differently deformed or lifted relative to one another and this internal deformation movement of the snow catching portion counteracts snow adhesion.
- the slot subdivides the snow catching portion into at least two adjacent subportions which are resiliently movable relative to one another. Due to the slot, the snow catching portion is thus weakened and at least two subportions on each side of the slot may mutually independently flex resiliently. Since the load on the snow catching portion from the underlying snow never applies uniformly over the entire snow catching portion, but instead, for example due to the slope of the ground or movement of the pole, two different loads are applied in the majority of situations to the at least two subportions, the two subportions deform or pivot to differing extents when the pole is planted in the snow and subjected to load. It has been found that due to this flexibility, which is imparted to the snow basket according to the invention, the resilient movements of the two subportions reduce snow adhesion.
- the length of the slot preferably amounts to at least roughly one third of the length of the snow basket measured in the direction of slot extension. Even for such slots, a more marked reduction in snow adhesion was observed.
- the length of the slot amounts to at least roughly half the length of the snow basket measured in the direction of slot extension, such that the greatest possible proportion of the snow catching portion may be subdivided into at least two blade-like subportions which are mutually independently deformable or movable.
- the slot may then in particular reach as far as a central portion of the snow catching portion or even completely cross over the central portion. Since the central portion is of particular significance in terms of statics to the deformation characteristics of the snow catching portion, such a far-reaching slot creates particularly good flexibility of the two subportions on each side of the slot.
- the snow basket still exhibits sufficient stability such that, while it yields somewhat under the compressive force of the snow in the course of elastic deformation of the subportions, it does not bend back completely, which would result in loss of the supporting function of the snow catching portion.
- mechanical stability against the snow catching portion bending back when pressure is applied to the pole may be increased by the upper side of the snow catching portion being curved upwards (towards the grip of the pole) in the manner of a shell.
- the connecting portion is located on a line which extends the extension of the slot.
- the two subportions of the snow catching portion on each side of the slot then extend from the connecting portion and may at this point both be held stable close to the pole.
- the flexible movement between the two subportions then primarily occurs at the distal ends of the two subportions remote from the connecting portion.
- the extension of the slot is substantially linear, such that the slot is simple to manufacture and has the least possible influence on other design features of the snow basket.
- the delimiting edges of the slot preferably extend substantially parallel to one another in order, on the one hand, to prevent the two subportions on each side of the slot from hindering their resilient movement and, on the other hand, to avoid relatively large passage holes in the snow catching portion.
- a slot with a width which varies along the direction of slot extension is, however, equally conceivable, for instance a slot which narrows inward from the edge.
- the subzones on each side of the slot should still be arranged adjacent one another, such that the subzones support one another when adhering snow is detached.
- a snow basket according to the invention may also comprise such an offset of the connecting portion relative to the central portion of the snow basket in one direction, i.e. be located in front of the central portion, the opening of the slot to the outer delimiting edge then preferably being offset with regard to the central portion in the other direction, i.e. being located therebehind.
- An optimised shape of the snow basket according to the invention, including the slot, is obtained if, in a projection of the snow basket in a plane orthogonal to the pole axis, normal rays which are located orthogonally on the outer delimiting edge do not intersect the snow basket and normal rays which are located orthogonally on the slot delimiting edges of at least one portion of the slot do intersect the snow basket. It has been established that this shape provides a good balance between good supporting behaviour and a low tendency to snow adhesion.
- the present invention achieves the stated object by providing a sports pole which comprises a snow basket according to any one of the preceding claims.
- a sports pole which comprises a snow basket according to any one of the preceding claims.
- the direction of slot extension is oriented substantially parallel to a forwards direction of the sports pole and that the connecting portion is arranged in front of the slot in the forwards direction of the sports pole.
- the two subportions on each side of the slot then extend backwards from the connecting portion and thus provide no obstruction to forwards movement on a mountain.

Abstract
The present invention provides a snow basket 16 comprising a connecting portion 24 by which the snow basket 16 is connected or connectable with a main body of a pole 10, and a snow catching portion 28 which extends out from the connecting portion 24 and comprises an outer delimiting edge 36, wherein the snow catching portion 28 comprises a slot 42 which reaches from the outer delimiting edge 36 to an inner portion 44 of the snow catching portion 28 and is open at the outer delimiting edge 36.
Description
- The present invention relates to a snow basket comprising a connecting portion by which the snow basket is connected or connectable with the main body of a pole, and a snow catching portion which extends out from the connecting portion and comprises an outer delimiting edge. The invention furthermore relates to a sports pole which comprises such a snow basket.
- Poles with snow baskets are part of the equipment for hikers, mountain climbers, touring skiers, mountaineers or the like and, on the one hand, allow the arms' muscle power to provide assistance when moving up the mountain and, on the other hand, offer security and grip by keeping the body balanced when climbing up or down or when setting off. The pole is held by the user in a grip zone and planted on the ground with a pole tip zone.
- A snow catching portion of known snow baskets generally has a plate- or dome-shaped contour and, to reduce weight, may comprise one or more orifices or also have a mesh-like structure. When the pole is stuck into the blanket of snow, the snow catching portion comes to a rest on the snow and prevents the pole from sinking too deep.
- As a result of the compressive force on the ski pole, in particular when climbing uphill, the snow is compressed under the snow basket and pressed against the snow catching portion, such that snow often remains stuck to the snow catching portion. When load is once more applied to the pole, the quantity of adhering snow may increase further until finally a large lump of snow is sticking to the snow catching portion and has to be laboriously removed by the user because it markedly increases the weight of the pole which has to be moved.
- The object of the invention is therefore to provide a snow basket for a pole, in particular a touring ski pole, which reduces the problem of snow sticking to the snow basket, such that less effort is required to clean the snow basket during use. Another object of the invention is to provide a sports pole with such a snow basket which permits use with the fewest possible interruptions for cleaning the snow basket.
- To achieve the above-stated object of the invention, the present invention provides a snow basket comprising a connecting portion, to which the snow basket is connected or connectable with a main body of a pole, and a snow catching portion, which extends out from the connecting portion and comprises an outer delimiting edge, wherein the snow catching portion comprises a slot which reaches from the outer delimiting edge to an inner portion of the snow catching portion and is open at the outer delimiting edge.
- The essential feature of the invention is thus a slot which is formed in the snow catching portion and reaches to the outer delimiting edge. It has been found that, thanks to such a slot, the mechanical stability of the snow basket for performing its supporting function can be retained, while markedly less snow sticks to the snow catching portion than in the case of a conventional snow basket which does not comprise such a slot. This result was not in any way to have been expected and was surprisingly identified in the course of testing by the inventor. One possible explanation for the reduced tendency of snow to stick may be that the slot modifies the deformation behaviour of the snow catching portion in such a manner that different subportions of the snow catching portion are differently deformed or lifted relative to one another and this internal deformation movement of the snow catching portion counteracts snow adhesion.
- This explanation is supported by the observation that it has proved particularly effective if the slot subdivides the snow catching portion into at least two adjacent subportions which are resiliently movable relative to one another. Due to the slot, the snow catching portion is thus weakened and at least two subportions on each side of the slot may mutually independently flex resiliently. Since the load on the snow catching portion from the underlying snow never applies uniformly over the entire snow catching portion, but instead, for example due to the slope of the ground or movement of the pole, two different loads are applied in the majority of situations to the at least two subportions, the two subportions deform or pivot to differing extents when the pole is planted in the snow and subjected to load. It has been found that due to this flexibility, which is imparted to the snow basket according to the invention, the resilient movements of the two subportions reduce snow adhesion.
- The length of the slot preferably amounts to at least roughly one third of the length of the snow basket measured in the direction of slot extension. Even for such slots, a more marked reduction in snow adhesion was observed. Preferably, however, the length of the slot amounts to at least roughly half the length of the snow basket measured in the direction of slot extension, such that the greatest possible proportion of the snow catching portion may be subdivided into at least two blade-like subportions which are mutually independently deformable or movable.
- The slot may then in particular reach as far as a central portion of the snow catching portion or even completely cross over the central portion. Since the central portion is of particular significance in terms of statics to the deformation characteristics of the snow catching portion, such a far-reaching slot creates particularly good flexibility of the two subportions on each side of the slot. At the same time, the snow basket still exhibits sufficient stability such that, while it yields somewhat under the compressive force of the snow in the course of elastic deformation of the subportions, it does not bend back completely, which would result in loss of the supporting function of the snow catching portion. As is known per se, mechanical stability against the snow catching portion bending back when pressure is applied to the pole may be increased by the upper side of the snow catching portion being curved upwards (towards the grip of the pole) in the manner of a shell.
- In a further preferred embodiment of the invention, the connecting portion is located on a line which extends the extension of the slot. The two subportions of the snow catching portion on each side of the slot then extend from the connecting portion and may at this point both be held stable close to the pole. The flexible movement between the two subportions then primarily occurs at the distal ends of the two subportions remote from the connecting portion.
- In a further preferred embodiment, the extension of the slot is substantially linear, such that the slot is simple to manufacture and has the least possible influence on other design features of the snow basket.
- The delimiting edges of the slot preferably extend substantially parallel to one another in order, on the one hand, to prevent the two subportions on each side of the slot from hindering their resilient movement and, on the other hand, to avoid relatively large passage holes in the snow catching portion. A slot with a width which varies along the direction of slot extension is, however, equally conceivable, for instance a slot which narrows inward from the edge. However, even at the slot opening, the subzones on each side of the slot should still be arranged adjacent one another, such that the subzones support one another when adhering snow is detached.
- In particular for ski touring use, it has proven advantageous for walking on a slope, even in a conventional snow basket, for the connecting portion to be offset to one side relative to a central portion of the snow basket, such that the extent of the snow catching portion on a side facing the slope is smaller than on a side of the pole remote from the slope. A snow basket according to the invention may also comprise such an offset of the connecting portion relative to the central portion of the snow basket in one direction, i.e. be located in front of the central portion, the opening of the slot to the outer delimiting edge then preferably being offset with regard to the central portion in the other direction, i.e. being located therebehind. The two subportions on each side of the slot, which according to the invention are mobile relative to one another, then extend on the side of the pole remote from the slope.
- An optimised shape of the snow basket according to the invention, including the slot, is obtained if, in a projection of the snow basket in a plane orthogonal to the pole axis, normal rays which are located orthogonally on the outer delimiting edge do not intersect the snow basket and normal rays which are located orthogonally on the slot delimiting edges of at least one portion of the slot do intersect the snow basket. It has been established that this shape provides a good balance between good supporting behaviour and a low tendency to snow adhesion.
- According to a further aspect, the present invention achieves the stated object by providing a sports pole which comprises a snow basket according to any one of the preceding claims. By means of a sports pole, the advantages and effects described above in connection with the respective embodiments of the snow basket according to the invention may be made exploitable for use in alpine and winter sporting applications, in particular in touring skiing.
- In a preferred embodiment of the sports pole according to the invention, it is proposed that the direction of slot extension is oriented substantially parallel to a forwards direction of the sports pole and that the connecting portion is arranged in front of the slot in the forwards direction of the sports pole. The two subportions on each side of the slot then extend backwards from the connecting portion and thus provide no obstruction to forwards movement on a mountain.
- The invention is explained in greater detail below on the basis of a preferred exemplary embodiment and with reference to the attached drawings, in which:
-
FIG. 1 shows a side view of a ski pole according to an exemplary embodiment of the invention, -
FIG. 2 shows a view from below of a snow basket zone of the ski pole shown inFIG. 1 , -
FIG. 3 shows a sectional view of the snow basket zone of the exemplary embodiment along a section line L inFIG. 2 , -
FIG. 4 shows a plan view of the snow basket zone of the exemplary embodiment, -
FIG. 5 shows a perspective view from below of the snow basket zone of the exemplary embodiment, -
FIG. 6 shows a front view of the snow basket zone of the exemplary embodiment, and -
FIG. 7 shows a perspective view from above of the snow basket zone of the exemplary embodiment. - A
ski pole 10 shown in side view inFIG. 1 comprises a stick-shapedmain body 12, agrip zone 14 arranged at the upper end of themain body 12, asnow basket 16 arranged at the lower end of themain body 12 and a pole tip zone 18 arranged at the bottommost end of theski pole 10. A pole axis direction S extends from thegrip zone 14 to the pole tip zone 18 along a pole axis AS. - The
grip zone 14 comprises agrip 20 with agrip loop 22. The ergonomic shape of thegrip 20 and the position of theloop 22 define a forwards direction V of theski pole 10, along which a user of theski pole 10, who is gripping theski pole 10 by thegrip zone 14 in a normal use position, moves forwards, the forwards direction V being defined parallel to a horizontal plane H. - The
main body 12 is formed of a light metal tube, the centre axis of which coincides with the pole axis direction S. Themain body 12 may comprise a telescopic tube system so that the length of thesports pole 12 may be adjusted. - The
snow basket 16 is fastened to themain body 12. In the exemplary embodiment, thesnow basket 16 is asymmetrical with regard to themain body 12, with a portion of thesnow basket 16 located in the forwards direction V being smaller than a portion of thesnow basket 16 located in a backwards direction opposite to the forwards direction V. In this manner, thesnow basket 16 also defines the same forwards direction V as thegrip zone 14. - The
snow basket 16 of theski pole 10 is hereinafter also explained in greater detail with reference toFIGS. 2 to 7 . - The
snow basket 16 is manufactured from a plastics injection moulding composed of a single material and comprises a connectingportion 24, to which thesnow basket 16 is connected with a lower end 26 of themain body 12, and asnow catching portion 28, which extends out from the connectingportion 24. - The connecting
portion 24 comprises a first bore 27 extending along the pole axis AS, into which thelower end 28 of themain body 12 is introduced, and comprises asecond bore 30 extending along the pole axis AS, into which ametal tip 32 is introduced from below. - The
snow catching portion 28 extends from the connectingportion 24 in the form of an upwardly curved, dome-like plate, in which are formedpassage openings 34 for reducing weight. As outer limit, thesnow catching portion 28 comprises an outerdelimiting edge 36 which, with the exception of a slot opening 38 to be described below, runs completely around thesnow catching portion 28 and the connectingportion 24. - At the slot opening 38, the outer
delimiting edge 36 develops intoslot delimiting edges 40, which delimit aslot 42 on both sides. Theslot 42 extends from the slot opening 38 into the interior of thesnow catching portion 28 and, in so doing, passes through somewhat more than half the length I of thesnow basket 24 measured in the direction L of slot extension. Theslot 42 extends along the forwards direction V from a rear end of thesnow basket 16 towards the connectingportion 24, in so doing reaching acentral portion 44 of thesnow catching portion 28. - The
slot 42 divides thesnow catching portion 28 into afirst subportion 46 and asecond subportion 48, which remain joined to one another only in the zone of the connectingportion 24 and are thus capable of deforming largely mutually independently in the manner of two blades. In particular, the twosubportions 46, 48 (depending on the elasticity of the material used, the thickness of the snow catching portion and the depth of the slot 42) are capable of flexing resiliently to a certain extent upwards or downwards in the pole axis direction S. It is here of particular significance to the effect according to the invention that the twosubportions - The design of the
slot 42 in the manner shown in the figures has proven effective for particularly effectively avoiding snow adhesion. As may be seen inFIGS. 2 and 4 , the delimiting edges of the slot extend substantially parallel to one another, i.e. the slot has substantially the same width b at all points along its direction of extension. The connectingportion 24 is offset relative to thecentral portion 44 of thesnow catching portion 28 in the forwards direction V, theslot opening 38 being arranged behind thecentral portion 44 with regard to the forwards direction V. -
FIG. 4 , which is a projection of thesnow basket 16 into a plane orthogonal to the pole axis AS, furthermore shows that normal rays N1-N5, which are located orthogonally on the outer delimitingedge 36 of thesnow catching portion 28, all point outwardly away from thesnow basket 16 and do not intersect thesnow basket 16. In contrast, normal rays K1, K2, K3 and K4, which are located orthogonally on theslot delimiting edges 40 of theslot 42, have directions such that they intersect the projectedsnow basket 16. It should here be noted that the rays N1-N5 and Kl-K4 in each case emerge from the delimitingedge 36 or theslot delimiting edges 40 and extend to infinity, although for reasons of illustration arrow directions are drawn inFIG. 4 and the further extension of the ray is indicated by dots. - While the
slot 22 does indeed divide thefirst subzone 46 and thesecond subzone 48 of thesnow catching portion 28 from one another along theslot 42, such that they are capable of mutually independently flexing to a certain extent, the slot is simultaneously configured such that the twosubzones snow catching portion 28 may be detached due to the fact that the different resilient movement of the twosubzones subzones subzones slot 42, bothsubzones slot 42 close to theslot opening 38, a slot width b between thesubzones snow basket 16, preferably no larger than approximately one tenth of the total width a of thesnow basket 16.
