Definitions

  • the present invention relates to a hockey stick, in particular for ice hockey, field or field hockey, rink-hockey or skater-hockey.
  • a hockey stick comprising a core of expanded vinyl chloride foam is described in the French patent published under No. 2,638,368.
  • the core which has the general profile of the stock, is clamped in a first braid made of glass fibers or carbon fibers, the assembly being placed and clamped in at least one other braid made of glass fibers or carbon fibers.
  • the sticks made of composite materials which have been proposed so far do not make it possible to obtain playing comfort comparable to that which is obtained with a conventional wooden stick.
  • the known butts made of composite materials produce vibrations in the hands of the players and wear out quickly.
  • the foams which have been proposed so far to constitute the core of the stock and in particular of the pallet produce a cavernous effect during the shock caused by the striking of the puck, which adversely affects good contact with the puck and good puck control.
  • the invention relates to a hockey stick as defined in claim 1.
  • said stick offers a gain in power compared to hockey sticks made of known composite materials, which results in an increase in the speed of the puck, as well as a much higher resistance to wear.
  • the third part 13 of the core must well absorb shocks so as to allow good control of the puck, during reception and dribbling for example.
  • a high density foam resistant to impact and impact will be used for this purpose, preferably having a density between 90 and 160 kg / m 3 .
  • This part can be cut, for example using a press, from a plate of non-crosslinked foam sold commercially under the brand KLEGECELL CW 80 (green foam), having for example a density of 100 kg / m 3 .
  • the third part 13 of the core can be cut from a glass / epoxy plate.
  • the three parts of the core are made integral, so as to facilitate the draping operation, by any suitable means, such as by stapling, sticky bandage or gluing.
  • Anchoring or interlocking members may be provided at the ends of the parts.
  • the core 13 can be partially or entirely upholstered, on one and / or the other of its faces, with a coating 14, 14 ′ of carbon or unidirectional glass, so as to increase the hardness of the pallet.
  • the length of this upholstery depends on the degree of hardness that one wishes to obtain. Keeping these pieces of carbon sheet or unidirectional glass in place can also be achieved by any suitable means, such as by stapling, sticking bandage or gluing.
  • Such a coating makes it possible to stiffen the pallet and to obtain better shooting accuracy.
  • this coating can be carried out not directly on the core, but on one of the braids 1, 2 and 3.
  • the core of the pallet can be extended at its end with a unidirectional carbon element 15 of a few centimeters in length, the dimensions and the shape of this element being able to be adjusted to the convenience of the player, without affecting the core. buttstock.
  • the draping using the braids can be carried out.
  • the braids are put in place by threading them successively through the free end of the handle, then by binding them together to their ends, for example using twine or an elastic element.
  • the braids can be made of carbon fibers, aramid, E glass, R glass, HP polyethylene (Dyneema), quartz, etc.
  • the first and third braids 1 and 3 are composed of carbon fibers, the second braid 2 being composed of a mixture of carbon fibers, quartz and polyethylene (for example fibers of the DYNEEMA brand), for example in a proportion of 50%, 25% and 25%.
  • Each braid can be made of fibers crossed at 45 °.
  • any other braiding of the fibers crossed between 30 ° and 60 ° can be provided, depending on the rigidity that one wishes to obtain.
  • the use of polyethylene fibers is advantageous in the event of the stock breaking, because these fibers, which are particularly resistant, do not separate and, therefore, significantly reduce the risk of injury to players.
  • one of the above braids can be replaced by a glass fiber, carbon fiber or hybrid braid, one or more of the glass or carbon wires being replaced by a filament made of visco-elastic material of the type used in the manufacture of skis or of polymeric fibers with liquid crystals or a mixture of the two.
  • a braid of this type allows a very significant reduction in vibrations.
  • a sock 4 comprising strands of unidirectional fibers 5 on two of its faces, as shown in FIG. 5, can be placed between the first and second braids, over all or part of the length of the sleeve from the heel, or localized along the handle, so that the unidirectional fibers are arranged on the side faces of the handle.
  • This sock is a reinforcement of the handle. It can, if necessary, be replaced by two strips comprising such strands of unidirectional fibers. The length of this sock or these bands will be proportional to the rigidity that one wishes to give to the sleeve.
  • the fibers can be glass, carbon or aramid fibers or a mixture.
  • the stock is impregnated using a resin, such as pure or modified epoxy resin or a thermoplastic resin, or any other particularly fluid resin, using the known process for impregnating fibers by low pressure injection RTM (Resin Transfer Molding), consisting of a resin transfer molding.
  • RTM Resin Transfer Molding
  • the use of this process allows an industrialization of the manufacture of the sticks, which was impossible with the manual impregnation techniques used until now.
  • this process makes it possible to obtain a better distribution of the resin, more uniform and homogeneous, than with the manual impregnation techniques used up to now.
  • the stock can still be steamed if necessary. Then, it can be covered with paint, the handle being able to be covered with a varnish with rough structure which prevents the stick from slipping in the hands of the player.
  • the hockey stick according to the invention offers resistance to wear which results from the materials of which it is composed.
  • particular emphasis should be placed on the new comfort of use and on the increased sensations of the players.
  • the stick gives an impression of solidity, flexibility and homogeneity so that the player can fully express himself.
  • the impression of homogeneity which is much stronger here than in traditional sticks, results, apparently paradoxically, from the use of different materials for each part of the stick. You would think that by using different materials, we achieve a result hybrid, bastard in a way. In fact, the opposite is achieved.
  • Each part having as main component a material perfectly adapted to local constraints, the increased impression of homogeneity results from the perfect adequacy of each part to its function.
  • the stick according to the invention is insensitive to variations in temperature and humidity.
  • the speed of the puck measured with a stick according to the invention, relative to the speed of the puck during a similar shot executed with a conventional wooden stick, is approximately 8.3% higher.
  • the weight gain compared to these conventional sticks can be up to 30%.
  • the torsional flexibility of the handle and the pallet are modular by varying the quantity, the nature and the length of the unidirectional fibers constituting the lateral reinforcements of the handle on the one hand and the size of the lateral unidirectional carbon sheets lining the sides of the pallet on the other hand.
  • the sticks according to the invention do not produce vibrations in the hands of the player, and as already mentioned, the cavernous effect is absent from the sticks according to the invention, thanks to the design of the pallet. It will also be noted that the hockey sticks according to the invention have a much greater resistance to wear than the sticks made of prior composite materials.
  • the hockey stick can be produced with a paddle having the characteristics described above, this paddle being mounted on a handle made of another material, such as for example aluminum.
