Definitions

  • the present invention relates to a ski pole according to the preamble of appended claim 1.
  • the invention is particularly directed to cross-country ski poles, so that ski poles for that application will be discussed in the rest of this disclosure for illuminating the invention but not restricting it thereto.
  • a ski pole having holding means comprising a substantially rigid support member having first support portions adapted to form a substantially rigid support to at least portions of the palm of a user of the ski pole while allowing the hand of the user to grip around the hand grip of a ski pole in a base position of the support member is known through EP 2 135 646 B1 .
  • the object of the present invention is accordingly to provide a ski pole of the type defined in the introduction being improved in at least some aspect with respect to such ski poles already known.
  • this ski pole further comprises a rigid element rigidly secured to an upper end of the shaft of the ski pole to project forwardly from the shaft in the running direction of a user when skiing and the shaft being in a state of extending vertically, and the support member is pivotally connected to the element around an axis at a location displaced forwardly with respect to the shaft in said state thereof.
  • a pivoting movement of the skiers hand is used to increase the length of the pole.
  • This pivoting movement of the wrist will also increase the speed of the skier.
  • the skiers hand is used as a lever to push the pole further backwards. This lever can only be used when the skiers hand is letting go of the pole at the very end of the push. Using this wrist movement, the pole can be pushed away further behind the skier and at a higher speed than without this pivoting movement.
  • the element projects from the shaft while making an angle to the shaft of at least 20°. It is preferred to have at least such a great angle between the element and the shaft, since the greater angle the more efficient start of the pivot movement of the holding means with a longer lever, although a great such angle at a fixed length of said element will lower the efficiency of the pole pushing at the end of the pivot movement with respect to a smaller such angle assuming that said axis is located at the same distance to the connection of the element to the shaft.
  • the element projects from the shaft while making an angle to the shaft of at least 30° or at least 45°. Such larger angles will increase the lever for pushing the skier forwardly in the beginning of the pivot movement of the holding means.
  • the element projects upwards from the shaft when the shaft is in said state. This results in an increased vertical distance between said axis and the wrist of a user in said state, which will especially improve the efficiency of the pole pushing in the middle and end phase of the pivot movement of the holding means.
  • said axis around which the support member is pivotally connected to said element is located at a distance of at least 2 cm to a prolongation of a centre axis of the shaft. This results in a substantial elongation of the lever pushing a user forward in the beginning of the pivot movement of the holding means.
  • the support member is pivotally connected to said element around an axis located at a distance of 2-6 cm or 3-5 cm to a prolongation of a centre axis of the shaft, which has turned out to be suitable locations of said axis for combining pole pushing efficiency and comfort of the user of the ski pole.
  • the support member has two substantially rigid portions which are connected to an upper region close to the upper shaft end of a first said support portion for the palm of a said user and which are extending in said base position apart to on opposite sides surround the back of the hand of a user and converge to be connected to said first palm support portion at a lower end of this portion close to the wrist of the hand of a said user.
  • the second of said two support portions is configured to support the metacarpus part of the four fingers of a hand of a user and a third of said two support portions is configured to support the thumb side of the wrist on the back side of the hand of a user.
  • said three support portions of the support member together provide comfortable support to a hand of a user of the ski pole.
  • said second and third support portions have arc-like extensions with the arc of the second support portions being shorter than the arc of the third support portion and which starts and ends inside the arc of the third support portion.
  • At least said second and third support portions of the support member are made of plastic.
  • Fig. 1 illustrates an upper part of a cross-country ski pole 1 having an elongated shaft 2 with a basket and tip not shown on the lower end for being pushed into the snow for pole-pushing.
  • a hand grip 3 is arranged around an upper end portion 4 of the shaft and configured to be gripped by a user of the ski pole.
  • the ski pole further comprises means 5 configured to hold a hand of the said user substantially fastened to said upper end portion 4 of the shaft while allowing a pivoting movement of the hand with respect to said upper end portion around an axis 6 extending substantially transversally to the running direction of said user when skiing for allowing said user to let loose the grip of the hand around the hand grip at an end phase of a pole pushing.
  • the holding means 5 comprises a substantially rigid support member 7 made of for example plastic or a synthetic material, such as a composite for lowering the weight thereof.
  • the support member 7 shown in this figure is designed to fit the right hand of a user, and it is shown how such a right hand 8 is held by the holding means.
  • the support member 7 has first support portions 9 adapted to form a substantially rigid support to the palm of a user while allowing the hand of the user to grip around the hand grip 3 in a base position of the support member shown in Fig. 1 .
  • the support member has also two substantially rigid support portions which are connected to an upper region close to the upper shaft end of a first said support portion 9 for the palm of a user and which are extending in said base position apart to opposite sides surrounding the back of the hand of a user and converge to be connected to said first support portion at a lower end of this portion close to the wrist of the hand of a said user when received in the holding means.
  • a second 10 of said two support portions is configured to support the metacarpus part of the four finger of a hand of a user and a third 11 of these two support portions is configured to support the thumb side of the wrist on the back side of the hand of a user. It is shown how the second and third support portions have arc-like extensions with the arc of the second support portion 10 being shorter than the arc of the third support portion 11 and which starts and ends inside the arc of the third support portion.
  • This in combination with the construction of the two support portions to be bendable to allow pushing and bending them towards each other after introduction of a hand of a user into an opening 12 surrounded by them enables adaption of the holding means to the hand of a user once received by the holding means. Selecting plastic as material for the second and third support portions is advantageous for obtaining this. To secure a hand introduced through the opening 12 even better a strap or the like may be applied and tightened to draw the two support members 10 and 11 towards each other and fixate them.
  • the ski pole further comprises a rigid element 13 rigidly secured to an upper end 14 of the shaft to project forwardly from the shaft in the running direction of said user when skiing and the shaft being in a state of extending vertically.
  • "Project forwardly” shall be interpreted as having one component of the extension thereof directed forwardly and not that the element has to make an angle of 90° with respect to the shaft, and in the embodiment shown in Fig. 1 this angle ⁇ is in fact about 60°.
  • the support member 7 is pivotally connected to the element 13 around said axis 6 at a location displaced forwardly with respect to the shaft as seen in said state.
  • the axis 6 is by this typically located at a distance of 2-6 cm to a prolongation of a centre axis 15 of the shaft.
  • Fig. 1 illustrates the location of the pivot axis 6 and wrist 17 in a start phase of a pivoting action.
  • Fig. 1 shows how a user of the ski pole is loosening the hand grip around the ski pole when beginning a pivoting action at the end phase of a pole push with the shaft being in a state of extending almost horizontally
  • Fig. 3 illustrates the levers obtained by the pole to act by the tip thereof onto the ground for getting the pole moving faster backwards than the hand gripping the pole.
  • a first lever 18 is defined by the distance between the wrist 17 of the hand and the pivot axis 6 in the running direction perpendicular to the ski pole. This first lever 18 is here greater in the state of the ski pole shown in Fig.
  • a second lever 19 directed perpendicularly to the first lever 18 and formed by the distance of the wrist 17 to the axis 6 in this direction needs to be kept as short as possible because the direction of the force generated by this lever is vertical to the desired direction and therefor the force used to move the pole through the second lever 19 will be wasted.
  • the distance defining the unwanted lever 19 at this start point of the pivoting movement will help to increase the lever 18 at the rest of the pivoting movement when the grip is tilted.
  • the lever 18 in Fig. 1 is efficient at the start of the pivoting movement, while the lever 19 in Fig. 1 is efficient at the end of the pivoting movement.
  • the invention is also applicable to other ski poles than for cross-country, such as alpine ski poles.
  • the angle made by the rigid element to the shaft is in this disclosure to be understood as the angle made to the shaft by a straight line extending from the upper end of the shaft to the axis around which the support member is pivoted.
