Abstract

A hockey stick has a head of conventional curved shape made of one plastics material. (I) and covered with a sheath made of another material (II). Pref. (II) is highly impact and abrasion resistant and can be applied by an overmoulding technique, opt. is of polyurethane. Pref. (I) is a relatively rigid, low cost material, pref. polypropylene, opt. is solid or expanded and filled with talc and/or a fibrous material. The core of the head may be integrally moulded with the handle- opt. the handle is partly covered with a fabric grip included as a mould insert. The prod. is cheaper and more durable than a conventional laminated wooden stick.

Description

t1 invention se rapporte à une crosse de hockey réalisée en matière plastique et à son procédé de fabrication
Pour sa rigidité et sa bonne résistance aux coups et frotte- ment s rélpdtés auxquels sont constamment soumises les crosses
ia lors de7tpratique du hockey, celles-ci sont, à ce jour fabri- quées en bois sculpté et de ce fait nécessitent une main d' oeuvre hautement qualifiée qui est rare d'où des délais de livraison très importants et des prix élevés, tout ceci pour une longévité guère supérieure à huit mois environ.t1 invention relates to a hockey stick made of plastic and its manufacturing process
For its rigidity and its good resistance to blows and friction s to which the sticks are constantly subjected
ia during the practice of hockey, these are, to date made of carved wood and therefore require a highly qualified workforce which is scarce hence very long delivery times and high prices, all this for a longevity little more than about eight months.

C'est pourquoi, depuis quelque temps, des fabricants ont tenté de mettre sur le marché des crosses de hockey fabriquées en matière plastique. This is why, for some time, manufacturers have tried to market hockey sticks made of plastic.

Dans un premier mode de réalisation, la crosse a été exécutée en une seule matière plastique moulée d'une seule pièce mais alors la matière utilisée soit résistait parfaitement mais avait un prix tel que la crosse atteignait un prix plus élevé que celui d'une crosse traditionnelle soit avait un prix acceptable mais ne résistait pas aux coups et frottements, d'autant plus qu'une crosse de hockey a dans sa partie courbe une forme très applatie et donc moins résistante. In a first embodiment, the stick was executed in a single plastic material molded in one piece but then the material used is perfectly resistant but had a price such that the stick reached a higher price than that of a stick traditional either had an acceptable price but did not resist knocks and friction, especially since a hockey stick has in its curved part a very flat shape and therefore less resistant.

Dans un autre mode de réalisation, sur un manche en tube de matière plastique extrudée, était emmanchée une tête massive en matière plastique moulée, ce qui, bien que de manière moins ai#e, posait le mame problème que ci-dessus et, de plus, conférait à la crosse, notamment à sa prtie courbe,, une épaisseur audelà de celle fixée par les normes pour les crosses de hockey, ce qui, mAme pour des jeux éducatifs, interdisait pratiquement leur utilisation. In another embodiment, on a handle made of an extruded plastic tube, was fitted a massive molded plastic head, which, although in a lesser manner, posed the same problem as above and, moreover, gave the stick, in particular its curved shape, a thickness beyond that fixed by the standards for hockey sticks, which, even for educational games, practically prohibited their use.

Un résultat visé par l'invention est une crosse en matière plastique de profil semblable voire identique à celui des crosses en bois, résistant aux coups et frottements auxquels la soumettr pratique du hockey et qui, néansoinstest d'un prix de revient très avantageux par rapport aux crosses en bois. A result targeted by the invention is a plastic stock with a profile similar or even identical to that of wooden sticks, resistant to knocks and friction to which subject it practice hockey and which, neansoinstest of a very advantageous cost price compared with wooden sticks.

A cet effet, l'invention a pour objet une crosse en matière plastique pour le hockey, notamment caractérisée en ce que la partie courbe comporte une couche superficielle qui est en matériau différent de celui réalisant lemme de cette partie courbe ainsi que le manche.  To this end, the invention relates to a stick made of plastic for hockey, in particular characterized in that the curved part comprises a surface layer which is made of a material different from that making the lemma of this curved part as well as the handle.

Elle a égalemeijt pcur objet, ce procédé de fabrication de cette crosse. It also has for object, this method of manufacturing this stick.

L'invention sera bien comprise à l'aide de la description ci-après faite, à titre d'exemple non limitatif, en regard du dessin ci-annexé qui représente, schématiquement, la crosse vue en coupe longitudinale. The invention will be better understood with the aid of the description given below, by way of nonlimiting example, with reference to the attached drawing which represents, schematically, the butt seen in longitudinal section.

En se reportant au dessin, on y voit la partie courbe 1 et, partiellement, le manche 2 d'une crosse 3. Referring to the drawing, we see the curved part 1 and, partially, the handle 2 of a stick 3.

Selon la caractéristique essentielle de l'invention, la partie courbe comporte une couche superficielle 4 qui est en matériau différent de celui réalisant lsâme 5 de cette partie courbe 1 ainsi que le manche 2 et ces matériaux différents sont choisis en fonction de leurs qualités respectives. According to the essential characteristic of the invention, the curved part comprises a surface layer 4 which is made of a material different from that making the core 5 of this curved part 1 as well as the handle 2 and these different materials are chosen according to their respective qualities.

Celui réalisant le manche 2 et l#amAe 5 de la partie courbe 1 sera choisi parmi ceux remplissant la double condition dun faible prix de revient et d'une grande rigidité telle le polypropylène, éventuellement chargé de fibres, par exemple de talc. Celui réalisant la couche superficielle 4 de la partie courbe 1 sera choisi pour sa haute résistance aux coups et frottements comme par exemple en polyuréthane dont le prix de revient assez élevé n'est plus un handicap étant donné la faible quantité nécessaire. The one carrying out the handle 2 and the amAe 5 of the curved part 1 will be chosen from those fulfilling the double condition of a low cost price and of a high rigidity such as polypropylene, possibly loaded with fibers, for example talc. The one producing the surface layer 4 of the curved part 1 will be chosen for its high resistance to knocks and friction, for example in polyurethane, the fairly high cost price of which is no longer a handicap given the small quantity required.

Ces deux parties 4 et 3 sont réalisées par moulage. L'une d'tales est moulée isolément puis intégrée au moule i coulée de l'autre pièce. Par exemple Ja partie formant le manche 2 et.  These two parts 4 and 3 are produced by molding. One of the plates is molded in isolation and then integrated into the mold i cast from the other part. For example, the part forming the handle 2 and.

l'amie 3 est moulée isolément puis l & e 3 est engagée, à la manière d'un noyau, dans le moule de la couche superficielle 4 qui étant coulée in situ , sera ainsi intimement liée à 1' âme 5 dont la surface pourra d'ailleurs présenter une certaine rugosité. Par ailleurs, en prévoyant lors de la réalisation de ltâme, épaisseur de la couche superficielle, lorsque la crosse sera finie, ladite couche ne formera pas de surépaisseur,
Grâce à ce procédé de fabrication de la crosse, celle-ci peut donc présenter exactement la même forme que les crosses de hockey traditionnelles et notamment peuvent être aplaties dans leur partie courbe 1 tout en étant extrêmement résistante et d'un prix compétitif.the friend 3 is molded in isolation and then l & e 3 is engaged, in the manner of a core, in the mold of the surface layer 4 which, being cast in situ, will thus be intimately linked to the core 5, the surface of which may moreover present a certain roughness. Furthermore, by providing during the production of the core, thickness of the surface layer, when the stock is finished, said layer will not form any additional thickness,
Thanks to this method of manufacturing the stick, it can therefore have exactly the same shape as traditional hockey sticks and in particular can be flattened in their curved part 1 while being extremely resistant and of a competitive price.

Evidemment,de même que certaines crosses traditionnelles, le manche 2 peut recevoir une garniture par exemple textile.  Obviously, like certain traditional sticks, the handle 2 can receive a lining, for example textile.
