Definitions

  • the present invention relates to equipment for climbing, such as technical ice climbing, extreme mixed climbing, dry-tooling or other paths implying similar difficulty.
  • tools are typically used having a maximum inclination of the handgrip of 45° and of the blade of about 100°, calculated with respect to the vertical of the wall.
  • axes which have a more reclined handgrip, between 55°-60° and a blade more inclined downwards with respect to the vertical of the wall to be climbed, so as to guarantee better hooking.
  • an alpinist desiring to tackle routes having different characteristics generally uses a tool that is specific and adapted to each path.
  • the present invention solves the problem of having a specific axe for each route by providing an axe that can be adapted to different conditions (e.g., technical ice-climbing, extreme mixed climbing and dry-tooling).
  • FIG. 1 represents two embodiments of an axe according to the invention
  • FIG. 2 shows an exploded detail of the axes shown in FIG. 1 ;
  • FIG. 3C shows a lateral view of the detail of FIG. 3B according to a variant
  • FIG. 4 represents a lateral view of inserts used in embodiments of the invention.
  • FIG. 5 shows a perspective view of a detail of a handgrip
  • FIG. 6A shows a perspective view of further details
  • FIG. 6B shows a lateral view of the details of FIG. 6A mounted on an axe according to one embodiment of the invention.
  • the axe 1 may comprise a main body 2 having a proximal portion 3 connected to a handgrip 6 and a distal portion 4 connected to a tool 5 .
  • proximal and distal relative positions shall be considered with reference to the handgrip 6 .
  • the tool 5 may be represented by a blade or pick, for facilitating the hooking to the progression support, for example ice, rock or wood.
  • the tool 5 may develop around a main axis Z, also referred to as longitudinal axis of the tool 5 .
  • the shape, length, width, thickness and profile of the tool may be determined by specific needs, as well as by the characteristics and difficulty of the intended use.
  • the handgrip 6 may comprise a core 6 a , generally made of metal or metal or carbon alloy, having—at the two ends—arched profiles 6 ′, 6 ′′ defining a grip space 7 therebetween.
  • the end 9 of the core 6 a proximal with respect to the point for connection with the main body 2 of the axe 1 , may comprise a perforated plate 9 a having, along a part of the perimeter thereof, a convex shaped toothed section 9 b.
  • the proximal portion 3 of the body of the axe may be removably connected to the handgrip 6 .
  • the proximal portion 3 of an axe may comprise connection means 7 for the removable connection with said handgrip 6 .
  • the two perforated plates 8 , 9 a are made to coincide, by aligning the respective holes.
  • Said removable coupling may be suitably fixed, for example, by means of a screw-nut system inserted in said aligned holes of the plates 8 , 9 a .
  • removable couplings such as, for example, a fitting system, a snap-coupling system or the like.
  • the toothed section 8 b of the connection means 7 of the proximal portion 3 of the main body 2 of the axe has a greater number of recesses with respect to the number of teeth constituting the toothed section 9 b associated to the handgrip 6 .
  • the number of recesses may be one more than the number of teeth
  • the angular distance between two adjacent teeth geometrically defines the angular adjustment of the handgrip 6 with respect to the main body 2 of the axe 1 , thus the angle ⁇ as defined above, as well as, as a consequence, the angle ⁇ between the axes X and Z.
  • the axe of the present invention advantageously allows for the transition between one conformation, for example that of FIG. 2A , to another, for example that of FIG. 2B , characterized by a different inclination of the handgrip and of the blade.
  • the passage from one configuration to another may be easily and rapidly obtained by unfastening the screw-nut system so as to disconnect the handgrip 6 from the main body 2 of the axe 1 , repositioning the handgrip 6 according to a different coupling configuration of the notched systems 8 a , 9 b and fastening the entirety for fixing the two parts mutually.
  • the present invention provides, inter alia, an axe in which it is possible to modify the inclination, defined as angle ⁇ in FIG. 1 , of the handgrip with respect to axis X of the axe.
  • the position of the handgrip may be modified so as to obtain an angle ⁇ of about 60°.
  • the angle ⁇ with the axis Z is about 105°, more suitable for use during competition, a mixed path or on dry-tooling, in which there is required the optimization on the grip of the tool when the athlete is offground.
  • the core 6 a in order to protect the core 6 a from external agents, as well as facilitate the grip and thus improve the manoeuvrability, the core 6 a may be covered through moulding or die-casting with a handgrip profile 6 b , typically made of plastic material; in turn, the plastic is totally or even only partly coated with rubber to make the handgrip more anatomic and comfortable.
  • the grip space 7 of the core 6 a has an ergonomic shape and comprises, at intermediate position between the proximal end 9 and the opposite end and in proximity of the internal edge of the grip space 7 , a through hole 10 .
  • the through hole 10 may be arranged in an approached position with respect to the proximal end 9 of the handgrip 6 , so that the distance separating the hole 10 from such end is less (for example, about one third) than the distance between the hole 10 and the opposite end of the handgrip 6 .
  • Such position may be selected so that the hole 10 is located about the separation point between the forefinger and middle finger of the user's hand and it may thus vary during the design step as a function of an accurate ergonomic study.
  • the handgrip profile 6 b may be interrupted, along the internal edge of the grip space 7 , at the through hole 10 , so as to create a U-shaped seat 11 in which a core portion 6 a remains exposed (as shown in FIG. 3A ).
  • Said seat 11 is intended to house an insert 12 , 12 ′ having a complementary shaped surface.
  • the inserts 12 , 12 ′ may develop around a longitudinal axis K and comprise a coupling portion 14 a , adapted to be housed in the seat 11 , and a separation portion 14 b having a more or less elongated shape with respect to said axis K.
  • the insert 12 , 12 ′ may be internally provided, in its portion for coupling 14 a with the seat 11 , with a slot, so that it is placed astride the exposed core portion 6 a.
  • the insert 12 , 12 ′ has—on one side—a hole 13 (not shown in FIGS. 3A , 3 B and 3 C), which may be aligned with the through hole 10 of the core 6 a and adapted to house the removably connecting and fastening means with seat 11 , typically a fastening screw.
  • a different form of coupling may be provided between the insert 12 , 12 ′ and seat 11 , for example a fit-coupling, a snap-coupling or the like.
  • the hole 10 in the seat 11 and the hole 13 in the insert 12 , 12 ′ may be omitted.
  • the grip space 7 may be divided, with reference to the proximal end 9 of the handgrip 6 , in a proximal portion 7 ′ and a distal portion 7 ′′ (as observable in FIGS. 1 and 3A ).
  • such distal portion 7 ′′ of the grip space 7 may comfortably house the little finger, the ring finger and the middle finger of the user, while the proximal portion 7 ′ may comfortably house the forefinger.
  • the user may advantageously maintain the grip of the tool more firmly, thus optimizing the use during rapid and lengthy ascents.
  • FIGS. 3B , 3 C and 4 Examples of inserts 12 , 12 ′ that may be inserted in the seat 11 , and representing a further object of the present invention, are represented in FIGS. 3B , 3 C and 4 .
  • the choice of the different length of the separation portion 14 b depends on the needs of the user, the size of the hand thereof and from the feeling of greater or lesser comfort desired.
  • the separation portion 14 b may be asymmetrically shaped in that it may have a smaller width with respect to the coupling portion 14 a and may develop along a parallel but offset direction with respect to the axis K.
  • the separation point between the forefinger and the other fingers of the hand may be slightly modified. Also this function increases the comfort for the user, showing the versatility of embodiments of the present invention.
  • each insert 12 , 12 ′ may be inserted in two different positions in the seat 11 , suitably rotating the insert 12 around the axis K.
  • the handgrip of the axe of the present invention may be modulated in an extremely personalized manner and while maintaining extreme comfort.
  • FIG. 5 A further aspect of the present invention is represented in the FIG. 5 .
  • the grip space 7 of the handgrip 6 may be reduced so as to adapt it to a hand of small dimensions.
  • a dowel 15 which may be associated, for example, by fitting it to the grip space 7 in proximity to the distal end of the handgrip.
  • Said dowel 15 may comprise a support surface 15 a for the user's hand, profiled so as to arrange it astride the handgrip 6 , and a support element 15 b , intended to end up in abutment with the arched profile 6 ′′ of the handgrip 6 .
  • Such dowel 15 may be made of any suitable material such as rubber.
  • the dowel 15 may be used to shorten the length of the grip space 7 , adapting it to the dimension of the user's hand.
  • the axe of the present invention may be used effortlessly by a user with smaller hands, such as for example, a young man or a woman.
  • the axe 1 may comprise a grip element 16 , intended to be positioned along the main body 2 of the axe 1 and has the function of supplementary support for the hand or alternatively the function of the insert 12 , 12 ′ described above, i.e. that of facilitating the handgrip of the axe being arranged between the forefinger and middle finger of the user's hand. It is thus important that this grip element 16 be capable of being arranged in any position along the main body 2 of the axe, depending on the preference or particular needs of the climber.
  • the grip element 16 may comprise a portion 17 for fastening to the main body of the axe 1 , being shaped as an open ring following the cross-section profile of the main body 2 .
  • the fastening portion 17 there may protrude two tongues 18 a , 18 b having complementary surfaces 20 for mutual coupling.
  • the first tongue 18 a is provided with a tooth 19 arranged on the surface 20 , to which there will correspond a complementary seat (not shown) on the surface of the second tongue 18 b faced thereto.
  • the first tongue 18 a also may comprise a through hole 21 perpendicular to the surface 20 , intended to house fastening means 22 , typically a screw, allowing for the closing of the fastening portion 17 around the main body 2 of the axe strongly enough to keep it firmly in the desired position.
  • fastening means 22 typically a screw
