Definitions

  • the present invention relates to a kit comprising:
  • Conventional handles of ski and other sports poles comprise a grip member of a substantially cylindrical shape disposed at the upper end portion of the ski pole with a hand strap in the form of a closed loop attached thereto, through which the user's hand is inserted upwardly.
  • a hand strap in the form of a closed loop attached thereto, through which the user's hand is inserted upwardly.
  • the point of attaching said hand strap to the grip is on the top of said grip.
  • Such a hand strap provides a proper grip for transfer of pushing forces to the pole.
  • the hand strap does not, however, keep the pole handle accommodated in the hand if the grip of the hand around the grip element ceases. When the hand drops the grip element while the pole is not in contact with a support surface, the pole will fall somewhat down and will hang in the strap, while will lie across the back of the hand or the wrist.
  • Poles having an hand strap capable to keep the hand accommodated also if the grip of the hand around the grip element ceases have been described.
  • An elastic auxiliary strap which is fastened to the grip element and is adapted to keep the grip element in a grip position relatively to the hand even if the hand releases the grip element is described in US5248163 .
  • WO013425 describes a ski pole handle with a possibility of adjusting the effective length of the hand strap according to the hand of the users.
  • EP0266329 describes a ski pole handle device which comprises a laterally protruding element which forms a supporting surface for the palm of the hand.
  • WO200707754 describes a grip handle having a main wrist strap and an additional strap in the form of a closed loop, wherein the point of attaching the additional strap to the grip handle member is disposed on the opposite side and higher in relation to the attaching point of the main wrist strap.
  • the cited ski pole handles are not capable to maximise the effectiveness of forces transmitted to the ski pole by the user.
  • the prior art constructions do not direct the force exerted by the hand that holds the handle entirely on the tip of the ski pole, in this manner wasting part of the forces exerted on the ski pole. This is a particularly felt need for ski poles to be used in competitive cross-country skiing, where the maximisation of the forces transmitted from the arms and the hands of the skier to the ski pole tip is an essential requirement to optimize the results obtainable.
  • the present invention relates to a kit comprising:
  • the construction of the present invention surprisingly maximises the transfer of pushing forces from the user's hand to the pole tip, as it will become evident from the figures and description that follow.
  • the kit of the present invention surprisingly solves the problem of entirely collecting the forces exerted by the user's hand forearm and arm and the problem of direct them entirely to the tip of the pole, without wasting part of said forces, as it commonly happens when using prior art constructions.
  • the kit of the present invention thus allows the maximization of the boost achievable by the user.
  • the kit of the present invention is schematically depicted in FIG. 1 . It comprises a pole (1) and a hand strap (3). Said pole (1) comprises a grip (2), a shaft (53) and a tip (51). Preferably, said pole comprises also a basket adapter (54) and a basket (52).
  • hand strap is here meant that element into which the hand user is inserted to hold the grip.
  • grip element is here meant that element which is suitable to be gripped by the hand.
  • Said pole has a longitudinal axis (L).
  • Said grip comprises at its bottom an hole for receiving said shaft. Grip, shaft and tip are aligned along the same longitudinal axis (L), wherein (L) is as defined above.
  • the kit of the present invention is characterised by the fact that the connection point (X) of said hand strap (3) to said grip (2) is located on said longitudinal axis (L).
  • the connection between said hand strap (3) and said grip (2) is obtained through coupling means (7).
  • Said coupling means (7) are permanent or snap connecting elements.
  • Permanent connecting elements are selected among the group comprising glue, screws, bolts.
  • Snap connecting elements are selected from the group comprising clip or webbing.
  • the hand strap of the present invention is schematically depicted in FIG. 1, 2 and 3 .
  • Said hand strap (3, 203, 303) comprises a dorsal portion (D) and a palmar portion (P).
  • Said dorsal portion (D) and palmar portion (P) are kept together by at least a first (12, 212), a second (13, 213) and a third (14, 214, 314) connecting portion.
  • Said connecting portions (12, 13, 14, 212, 213, 214, 314) comprise a bending line (B), delimiting a dorsal face comprising the dorsal portion (D) and a palmar face comprising the palmar portion (P) on said hand strap (3, 203, 303).
