Definitions

  • the present invention relates in general to a ski pole hand grip. More particularly, the present invention relates to a ski pole hand grip that enables the hand to automatically engage the grip and ski pole in a more natural position and thus more optimally permit proper functional orientation of the hand, forearm and arm.
  • Ski poles have traditionally been made with a vertical shaft that supports at its top end ski pole grip.
  • the ski pole grip is on the same axis as the ski pole shaft thus resulting in the positioning of a hand so that the thumb faces superiorly and medially.
  • the medial portion of the hand on the fifth digit side thereof is directly inferiorly or downward towards the earth's surface. This results in the palms facing medially or towards each other when the ski poles are held in their natural vertical position with the arms extended in front of the individual.
  • the hand is held in a vertical or near vertical position so that if an imaginary line were drawn through the second, third, forth and fifth digits it would be parallel to the ski pole shaft and perpendicular or near perpendicular to the earth's surface.
  • U.S. Patent 3,933,642 to With shows an angled or curved ski pole shaft.
  • U.S. patent 3,085,814 to Scott and U.S. Patent 3,436,090 to Lange et al. also illustrate a slight angulation of the shaft adjacent to the grip connection to the shaft.
  • the hand grip is vertical.
  • U.S. patent 3,582,100 to Allsop also illustrates an angulation at the top of the ski pole shaft. None of the above patents illustrate a resulting hand position that is very different from that of the traditionally-held vertical axis position.
  • the proposed invention is an attempt to rectify the inherent disadvantages of the traditional ski pole grip orientation relative to the hand.
  • THe proposed grip is oriented such that when the hand fully engages the grip, the palm or ventral surface of the hand faces downward towards the earth's surface.
  • the plane of the ventral surface of the hand is parallel or near parallel to the plane of the earth's surface.
  • the second through fifth digits extend forward and then downward thus wrapping around the molded body of the grip resulting in the placement of the very distal ends of the digits on the inferior surface of the grip and thus opposing the palm or ventral surface of the hand.
  • the thumb has its own molded section of the grip locating the thumb medially and inferiorly wrapping around the extension flange from the main body of the grip, resulting in its placement opposing the second digit, but not touching any of the four remaining digits.
  • There is a lateral extension flange from the main body of the grip which extends over the dorsal surface of the hand just proximal to the metacarpal joints stopping over the second digit.
  • This flat extension has inherent flexibility such that it retains the grip to the hand, but allows immediate disengagement. With the horizontal positioning of the hand when engaged with the ski pole grip, this allows a drastically increased range of motion at the wrist joint.
  • the wrist can fully extend and flex two to three times the maximum range of motion when flexing and extending as opposed to the vertically positioned hand.
  • the wrist is also oriented such that it can function with significantly greater strength because of the improved positioning of the hand, wrist, forearm and arm musculature.
  • the hand and arm are more capable of absorbing impact from the process of pole planting in the act of skiing downhill or cross country.
  • the medially and inferiorly positioned thumb there is a very significant lessening or elimination of impact induced torsional strain and thus results in fewer injuries to the thumb.
  • this invention's proposed hand placement poling along horizontal or uphill surfaces is also more efficient and stronger.
  • FIGS. 1-4 illustrate a preferred embodiment of the ski pole hand grip of the present invention. It is noted that in accordance with the invention, the hand gripping surface is disposed horizontal or substantially horizontal, which is totally opposite to the common type of vertical arrangement of hand grip.
  • a ski pole that is of generally cylindrical shape and that may have a standard type of configuration at the bottom thereof such as illustrated in FIGS. 1. It is to be understood that the hand grip of the present invention may be adapted for use with any type of ski pole and ski pole shaft construction.
  • a ski pole shaft 10 which is of generally cylindrical construction and which may be made of various types of materials such as metal, or petrochemical derivatives or composites.
  • the ski pole shaft 10 receives the hand grip of the present invention.
  • This hand grip includes a vertical section 11. It is the vertical section 11 that engages and attaches the hand grip to the ski pole shaft 10.
  • the vertical section 11 is cylindrical and is internally at least partially hollow so as to receive the ski pole shaft. This section is vertical and perpendicular to the earth's surface.
  • the vertical section 11 ends at the bend 12 where the structure turns into a secondary cylindrical section 13, as clearly illustrated in FIG. 2 that angles away from the vertical at a preferred range of angles to be described hereinafter.
  • These two cylindrical sections 11 and 13 are reinforced by a laterally placed reinforcing ridge 14 that strengthens the member at the bend 12.
  • a similar reinforcing ridge 15 that is adapted to reinforce and strengthen the angulation created by the angled relationship between section 13 and the hand grip generally illustrated at 16.
  • FIG. 2 illustrates another angle referred to in FIG. 2 as angle B which is illustrative of a preferred range of angles that the hand grip is disposed relative to the horizontal, but preferably close to a horizontal position.
  • angle B is another angle referred to in FIG. 2 as angle B which is illustrative of a preferred range of angles that the hand grip is disposed relative to the horizontal, but preferably close to a horizontal position.
  • imprint depressions there are a plurality of imprint depressions to receive the fingers of the hand.
  • imprint depression 18 to receive the fifth digit of the hand
  • an imprint depression 19 to receive the fourth digit
  • an imprint depression 20 to receive the third digit
  • an imprint depression 21 to receive the second digit.
  • imprint depression 22 that is adapted to accept the thumb.
  • FIG. 1 note FIG. 1 and the placement of the thumb 22A in this imprint depression 22.
  • FIG. 1 the overall hand position with the hand interlocked with the four digits in the finger depressions and the thumb in the thumb imprint depression.
  • FIG. 2 which shows the placement of the second digit 21A opposed to the thumb 22A on essentially either side of the medial flange 23.
  • the imprint depressions are formed with elevated ridges therebetween such as the ridges 24, 25, and 26 illustrated in FIG. 4. These ridges separate the second and third digits, the third and fourth digits and the fourth and fifth digits, respectively.
  • the most lateral border of the hand grip is at 27. This provides support to the medial border of the hand. From the border 27, the hand grip extends in a flexible band 28 which extends over the knuckles of the second through fifth digits as clearly illustrated in FIG. 2. Thus, this enclosing band 28 forms a retaining extension from the grip which superiorly covers the fifth, fourth, third, and second proximal portions of the digits just proximal to the respective metacarpal joints. At the base 29 of the band or extension, the member is relatively rigid and becomes more flexible as the band becomes narrower toward the free end thereof.
  • the band 28 have a sufficient amount of flexibility as this allows the entire hand to be quickly disengaged from the ski pole grip through the opening that is present between the medial flange 23 and the band or extension 28. Also, because of the retaining extensions flexibility, this allows even more simplified disengagement.
  • a section 30 that represents an elevated portion which supports the ventral surface and central depression area of the palm of the hand.
  • the horizontal palm support flange 31 which supports the entire ventral surface of the palm as far as the wrist joint at the crease of the hand.
  • FIG. 1 represents a view of the medial left side of the right hand ski pole grip. This view clearly illustrates the medial flange 23 and its associated thumb imprint depression 22. FIG. 1 also shows the horizontal palm support flange 31 which supports the entire ventral surface of the palm. FIG. 1 also shows the flexible retaining extension 28.
  • the axis of the hand grip 16 at either a horizontal position or preferably at a position slightly angled from the horizontal as illustrated by the angle B in FIG. 2.
  • This angle may be in the range of 0°-45°, but is preferably in the range of 0°-30° to the horizontal.
  • the near horizontal palm support flange 31 is as illustrated in FIG. 3 is lower than the lateral when the hand completely engages the grip.
  • the hand grip 16 be placed in a manner wherein the force center of the hand is represented by the line L3 in FIG. 2 is substantially in line with the axis L4 of the section 11 and of course, also in line with the axis of the ski pole shaft. In this way, the vertical shaft axis is congruent with the center of effort placed on the ski pole grip which would be near to the center of the palm.
  • the lines L3 and L4 for the most part are in line indicating this relationship. This provides for direct and immediate force transmission from the hand to the ski pole shaft.
  • the angular relationship of the hand grip to the ski pole shaft is illustrated as being fixed.
  • This angular adjustment may be provided by a standard interlocking pivot structure.
  • the ski pole hand grip of the present invention may be constructed of many different types of materials, but preferably is constructed for the most part of a hard durable plastic material.
  • the only portion of the grip that is not of a rigid material is the flexible extension 28.
  • the main part of the hand grip along with the base of the extension may be made of a rigid plastic material and then in a second step, a more flexible material may be added to the hand grip forming the extension 28.
  • the flexibility at the extension 28 is desired so as to enable easy disengagement of the hand from the ski pole so as to prevent accidents.
