Definitions

  • the invention relates to a hockey stick according to the preamble of claim 1.
  • hockey sticks include both ice hockey sticks and street hockey sticks or the like.
  • Hockey sticks are usually made from multi-ply wood structures, with a pure wooden stick made of layer-glued veneers being used in the lower price ranges.
  • glass fiber reinforced plastics or carbon fiber reinforced plastics or combinations thereof are used in the more stressed areas of the wooden stick in order to increase the resistance.
  • the blade of the hockey stick is usually made up of a wooden core consisting of laminated wood or solid wood and straps on both sides made of glass fiber or carbon fiber reinforced plastics.
  • the object of the present invention is therefore to provide a hockey stick which ideally combines the properties of cheap manufacture and low weight, the disadvantages of the known hockey sticks being reduced or avoided.
  • the openings of the honeycomb are directed towards the face of the blade.
  • thin wood veneers or the like or lateral cover laminates are arranged between regions of the lightweight cores. This further increases the strength without significantly increasing the weight.
  • the hockey stick is coated on the outside with glass fiber or carbon fiber reinforced plastics. This further increases the resilience.
  • inserts made of solid wood are used in the region of the cone, that is the point that adjoins the shovel of the racket.
  • the insert can be designed as a single or multi-part insert. The use of solid wood inlays enables the forces to be transferred better.
  • FIG. 1 is a plan view of a hockey stick of the usual type in a schematic representation
  • FIG. 2 is a side view of the racket of FIG. 1
  • FIG. 3 is a section of the racket along the line III-III of FIG. 2 with the structure according to the invention
  • FIG. 5 shows a section similar to FIG. 4 with a modified structure of the shaft
  • FIG. 6 shows a plan view of the blade of the racket with a cutout for making the internal structure of the blade visible
  • Fig. 7 is a section along the line VII-NII of Fig. 6, and
  • Fig. 8 shows a variant of the shaft of the racket.
  • the hockey stick has a shaft 1 and a blade 2 which protrudes from the shaft 1 at an angle, preferably between 90 ° and 140 ° degrees.
  • Both the shaft 1 and the blade 2 have, as an essential component, a lightweight core 13 based on honeycombs, in particular made of plastic or paper strips, which are coated with resin systems. Of course there is also the possibility to add other light materials use.
  • the shaft 1 has a wooden insert 3 at its blade-side end. As FIG. 2 shows, the wooden insert 3 forms a conical connecting piece between the shaft 1 and the blade 2.
  • This wooden insert 3 can have one or more layers be formed, the layers being substantially parallel to the face. However, it is also possible to do a differently oriented stratification.
  • at least in the transition part between the lightweight core 13 of the shaft 1 and the lightweight core 13 of the blade 2 there is no need for a side cover for the hockey stick.
  • Fig. 4 shows a portion of the shaft 1 of the hockey stick in a diagrammatic representation, the shaft 1 on the outside opposite one another in each case a laminate 10 and then a wood veneer panel 12 and between the wood veneer panels 12 has a honeycomb-shaped lightweight construction 13, which on its two outer sides is covered by a wood veneer panel 12 '.
  • the construction of the lightweight core corresponds to the core according to Swiss patent CH 666 410, according to which the core consists of successive layers, each of which consists of a corrugated and adjoining flat paper or plastic strip, which is impregnated, and preferably a coating of resin or Has resin system.
  • the corrugated strips can be offset from one another by half a wavelength, wherein the wavy strips can be glued to the flat strips in the region of the wave troughs or wave crests to the flat strips.
  • the lightweight core 13 preferably has the same height as the wooden veneer panel 12 ', so that when the shaft 1 is assembled by the wooden veneer panels 12, the lightweight core 13 is not compressed or damaged or destroyed.
  • the lightweight core 13 is installed so that the openings of the honeycomb face the wood veneer panels 12.
  • laminates made of glass fiber reinforced or carbon reinforced plastic (GRP / CFRP laminates) similar to the laminates 10 can also be used.
  • intermediate layers 4 made of wood veneer or GRP / CFRP laminates or similar material instead of the flat strips 13 "or 13 present in the previous embodiment of the lightweight core 13 in addition to these available.
  • the flat strips 13 ′′ can be present on one or both sides of the intermediate layer 4.
  • a simple cover made of wood, GRP / CFRP laminates and similar material can be provided on one or both sides as the front cover.
  • the lightweight core 13 is enclosed by a sheathing 5 made of fiber-reinforced plastic, the lightweight core 13 at the longitudinal ends inside the sheathing 5 with an insert 6 or 6 'made of wood or plastic is provided.
  • the construction of the lightweight core 13 corresponds to that of the lightweight core 13 of the shaft 1 according to FIG. 4 or 5, the openings of the honeycombs being located on the face side or on the opposite side.
