Definitions

  • the present invention relates to a snow plate comprising a connecting portion to which the snow plate is connected or connectable to a stick main body of a stick, and a snow guard portion extending from the connecting portion and having an outer boundary edge. Furthermore, the invention relates to a sports stick having such a snow plate.
  • Sticks with snow plates belong to the equipment of hikers, mountaineers, touring skiers, mountaineers or the like and allow on the one hand a support of the upward movement on the mountain by the muscular strength of the arms and on the other hand provide security and support by supporting the balance of the body during ascent and descent or at the departure.
  • the stick is grasped in a grip area by the user and placed on the ground with a stick tip area.
  • a snow guard portion known snow plate has generally plate-shaped or hood-shaped contour and can have one or more openings to reduce weight or have a mesh-like structure.
  • the snow guard section is supported on the snow as the cane dives into the snow cover and prevents the cane sinking too far in the snow.
  • the snow Due to the pressure force on the ski pole, especially when climbing the mountain, the snow is compressed under the snow plate and pressed against the snow guard section, so that often snow sticks to the snow catcher section.
  • the amount of adhering snow can continue to increase until finally a larger snow clot adheres to the snow guard section and from the User has to be removed with difficulty, since he significantly increases the weight of the stick to be moved.
  • the object of the invention is therefore to provide a snow plate for a stick, in particular a touring ski pole, which reduces the problem of snow sticking to the snow plate, so that less effort is required to clean the snow plate during use. It is another object of the invention to provide a sports pole with such a snow plate, which allows use with as little interruptions to clean the snow plate.
  • the present invention provides a snow plate comprising a connecting portion to which the snow plate is connected or connectable with a stick main body of a stick, and a snow guard portion extending from the connecting portion and having an outer peripheral edge Snow guard portion has a slot which extends from the outer boundary edge to an inner portion of the snow guard portion and is open at the outer boundary edge.
  • An essential feature of the invention is thus a slot which is formed in the snow guard portion and extends to the outer boundary edge. It has been found that by such a slot, the mechanical stability of the snow plate can be ensured to exercise its support function, but significantly less snow adheres to the snow guard portion than in a conventional snow plate, which does not have such a slot. This result was not to be expected in any way and was surprisingly found in experiments of the inventors. One possible explanation for the reduced tendency of snow adhesion may be seen in the fact that the slot changes the deformation behavior of the snow guard section such that different sections of the snow guard section deformed or raised differently from each other and this inner deformation movement of the snow guard section counteracts the adhesion of snow.
  • the slot divides the snow guard section into at least two adjacent sections, which are elastically movable relative to each other.
  • the slot of the snow guard portion is thus weakened and at least two sections on both sides of the slot can bend independently elastically. Since the load on the snow guard portion of the underlying snow never uniformly over the entire snow guard section acts, but - for example, due to the inclination of the ground or a movement of the stick - on the at least two sections in the predominant situations, two different loads are exerted, deform or the two sections pivot to different degrees when the stick is put into the snow and loaded. It has been found that due to this flexibility, which is given to the snow plate according to the invention, the elastic movements of the two sections reduce an adhesion of snow.
  • the length of the slot is at least approximately one third of the measured in the direction of the slot length of the snow plate.
  • the length of the slot is at least approximately half of the measured in the direction of the slot length of the snow plate, so that the largest possible part of the snow guard portion can be divided into at least two wing-like sections, which are independently deformable or movable.
  • the slot can then in particular up to a central portion of the Snow guard section or even cross the central section completely. Since the central portion has particular static importance for the deformation properties of the snow guard section, a particularly good flexibility of the two sections on both sides of the slot is created by such a far-reaching slot.
  • the snow plate still has sufficient stability to give way to the compressive force of the snow in the context of the elastic deformation of the sections, but not completely wegknknicken, which would lead to a loss of support function of the snow guard section.
  • the mechanical stability against buckling of the snow guard portion when leaning on the stick can be increased by the fact that the snow guard portion is cupped with upwardly curved (up to the handle of the stick) arched top.
  • the connecting portion lies on an extension line of the course of the slot.
  • the two sections of the snow guard section on both sides of the slot then extend from the connecting section and can both be stably held near the pole at this point.
  • the flexible movement between the two sections then takes place above all at the distal ends of the two sections, away from the connecting section.
  • the course of the slot is substantially rectilinear, so that the slot is easy to manufacture and influences the other design of the snow plate as little as possible.
  • the slot boundary edges are substantially parallel to each other, on the one hand to prevent the two sections on both sides of the slot do not interfere with their suspension movement and on the other hand to avoid larger through holes in the snow guard section.
  • a slot with along the course of changing slot width such as a slit narrowing from the edge inwards. But even at the slot opening, the subregions on both sides of the slot should still be arranged adjacent to each other, so that the subregions support each other in releasing adhering snow.
  • a snow plate according to the invention may have such an offset of the connecting portion with respect to the central portion of the snow plate in one direction, i. are in front of the central portion, in which case preferably the opening of the slot is offset to the outer boundary edge with respect to the central portion in the other direction, i. lies behind it.
  • the two sections on both sides of the slot, which are according to the invention to each other movable, then extend on the side facing away from the slope of the stick.
  • An optimized shape of the snow plate according to the invention, including the slot, results when in a projection of the snow plate in a plane orthogonal to the pole axis normal rays which are orthogonal on the outer boundary edge, no intersection with the snow plate and normal rays, which orthogonal to the slot boundary edges stand at least a portion of the slot, cut the snow plate. It has been found that this shaping provides a good balance between a good support behavior and a low tendency to snow adhesion.
  • the present invention provides a sports pole having a snow plate according to one of the preceding claims for the purpose of achieving the above-mentioned object of the invention.
  • a sport pole With a sport pole, the advantages and effects described above in connection with the respective embodiments of the snow basket according to the invention can be utilized for use in the alpine area and in the winter sports area, in particular in the field of touring skiing.
  • the course direction of the slot is oriented substantially parallel to a forward direction of the sports stock and that the connecting portion in the forward direction of the sports stock is arranged in front of the slot.
  • the two sections on both sides of the slot then extend from the connecting portion to the rear and thus do not interfere with the forward movement of the mountain.
  • Skistock 10 shown in side view comprises a rod-shaped main body 12, a grip area 14 arranged at the upper end of the main body 12, a snow plate 16 arranged at the lower end of the main body 12, and a pole tip area 18 arranged at the lowermost end of the ski pole 10. From the grip area 14 to the pole tip area 18 towards a pole axis S along a pole axis S.
  • the grip region 14 has a handle 20 with a grip loop 22.
  • the ergonomic shape of the handle 20 as well as the position of the strap 22 define a forward direction V of the ski pole 10 along which a user of the ski pole 10 grasping the ski pole 10 in normal use position on the handle portion 14 advances, the forward direction V parallel to a horizontal plane H is defined.
  • the main body 12 is formed of a light metal tube whose central axis coincides with the pole axis direction S.
  • the main body 12 may include a telescoping tube system to adjust the length of the sports stock 12.
  • the snow plate 16 is fixed to the main body 12.
  • the snow plate 16 is asymmetrical with respect to the main body 12, and a forward direction V portion of the snow table 16 is smaller than a reverse direction to the reverse direction V opposite portion of the snow plate 16. In this way, the snow plate 16 also defines the same forward direction V as the grip area 14.
  • the snow plate 16 of the ski pole 10 will be described below with reference to FIGS. 2 to 7 explained in more detail.
  • the snow plate 16 is made of a unitary plastic injection-molded part and comprises a connecting portion 24, on which the snow plate 16 is connected to a lower end 26 of the main body 12, and a snow guard portion 28 which extends from the connecting portion 24.
  • the connecting portion 24 has a first, along the axis of the axis AS extending bore 27 into which the lower end 28 of the main body 12 is inserted, and has a second, along the axis of the axis AS extending bore 30, in which from below a metal tip 32 is inserted is.
  • the snow guard portion 28 extends from the connecting portion 24 in the form of an upwardly domed, hood-like plate into which passage openings 34 are inserted for weight reduction.
  • the snow guard portion 28 has an outer boundary edge 36 which completely surrounds the snow guard portion 28 and the connecting portion 24 except for a slot opening 38 to be described below.
  • the outer boundary edge 36 merges into slot boundary edges 40, which delimit a slot 42 on both sides.
  • the slot 42 extends from the slot opening 38 into the interior of the snow guard section 28 and passes through slightly more than half of the measured in the direction L length I of the snow plate 24.
  • the slot 42 extends along the forward direction V of a rear end of the snow plate sixteenth toward the connecting portion 24. He reaches into a central portion 44 of the snow guard section 28.
  • the slot 42 divides the snow guard portion 28 into a first portion 46 and a second portion 48, which are interconnected only in the region of the connecting portion 24 and thus can deform largely independently of each other in the nature of two wings.
  • the two subsections 46, 48 (depending on the elasticity of the material used, the thickness of the snow guard portion and the depth of the slot 42) may elastically bend up or down to a certain extent in stick axis direction S. It is of particular importance for the effect according to the invention that the two sections 46, 48 can bend by different amounts.
  • the design of the slot 42 in the manner shown in the figures has been found to be effective in order to avoid effectively adhering to the snow.
  • FIGS. 2 and 4 It can be seen that the slot boundary edges are substantially parallel to one another, ie the slot has substantially the same width b at all points of its course L.
  • the connecting portion 24 is offset from the central portion 44 of the snow guard portion 28 in the forward direction V, the slot opening 38 being located behind the central portion 44 with respect to the forward direction V.
  • FIG. 4 representing a projection of the snow plate 16 in a plane orthogonal to the pole axis AS, that normal rays N1 - N5 which are orthogonal on the outer boundary edge 36 of the snow guard portion 28, all pointing outwardly from the snow plate 16 and have no intersection with the snow plate 16 .
  • normal beams K1, K2, K3 and K4 which are orthogonal to the slot boundary edges 40 of the slot 42 have such directions as to intersect the projected snow plate 16.
  • the rays N1 - N5 and K1 - K4 emanate respectively from the boundary edge 36 and the slot boundary edges 40 and reach to infinity, albeit in FIG. 4 for illustration reasons Arrow directions are drawn and the further beam path is indicated by dots.
  • slit 22 separates first portion 46 and second portion 48 of snow guard portion 28 along slit 42 so that they may bend independently to some extent, at the same time, the slit is configured to accommodate both portions 46, 46. 48 are still arranged spatially next to each other or adjacent to each other. This has the effect that a larger snow clump, which already shows the tendency to adhere to the snow guards section 28, can be solved by the fact that the different suspension movement of both subregions 46, 48 removes the snow clot from both subregions 46, 48, wherein it can be seen that the two sections 46, 48 assist each other in the detachment process.
  • a slot width b between the portions 46, 48 should not be greater than about a quarter of the total width a of the snow plate 16, preferably should not be greater than about one-tenth the total width a of the snow plate 16.
