Abstract
In this document is described an ice-hokey stick comprising an essentially straight stick shaft (1) and a blade (2) attached to the lower end of the shaft and sideways aligned to an angle relative to the shaft. According to the invention the stick includes at least one oblong reinforcement part (4, 5) extending from the center toward each stick shaft end, with a cross section diminishing toward the ends of the stick shaft (1), whereby the stiffness of stick shaft (1) is variable in the longitudinal direction of the stick shaft so that the stiffest area of the stick shaft (1) is approximately at the midpoint of the shaft (1), that is, the lower hand grip point of the player using the stick, and the shaft stiffness diminishes from the grip point toward the ends of the stick shaft.
Description
216 ~ 6 9 9 WO 95/01820 ; PCT/~94/00318 Ic~hockey stick The present invention is related to an ice hockey stick according to the preamble of the claim 1.
Several different methods of striking the puck are used in the game of ice-hockey.
The highest speed for the puck is att~ined by a slap shot in which the player's lower hand holding the stick at its lower part and stick are rotated at the side of the player's body behind the body, and the puck is then shot vigorously forward 0 by rotating the body and ~imlllt~neously se-n-ling the lower hand with the stick energetically forward. In this manner the puck is accelerated by the stick blade at an extremely high speed in a succe~ful shot, and the puck is provided with a maximum speed, thereby giving the goalkeeper a minimllm time to react to the appro~ ing puck.
The flexibility of the stick shaft is extremely im~ t for ~tt~ining a powerful shot. When the stick blade hits the puck, the blade is bent backward and the stick shaft is flexed ~l~v~d at the player's lower hand. As the shafts of conventionalsticks have a constant cross section over the entire length of the stick shaft, and consequently, a constant stiffn~, the stick is obviously flexed maximally at theplayer's lower hand which pushes the stick folw~d. However, such a function of the stick fails to impart maximum energy to the shot. As the maximum deflection of the stick shaft occurs at the midpoint of the shaft, the ends of the stick shaft remain almost unbent, whereby the el~cticity of the whole stick shaft length remains marginally utilized in the shot. Thus, a portion of the shot input energy is con~me~i in bending the shaft and thus will not contribute to the puck speed as it leaves the stick blade.
It is an object of the present invention to achieve an ice-hockey stick suited to impart a maximum acceleration to the puck in a slap shot through improved utili7~tion of the elasticity of the stick shaft.
Wo 95/01820 216 ~ ~ ~ 3 PCTtFI94/00318 ~
The invention is based on dçcigning the stick shaft stiffness to be nonconstant so that the highest stiffness of the shaft coincides at least essentially with the lower hand of the player using the stick and then fall off toward the lower shaft end or both shaft ends.
More specifically, the ice-hockey stick according to the invention is characterized by what is stated in the characterizing part of the claim 1.
The invention offers significant benefits.
By virtue of the present invention, the energy imparted by the player to the shot is utilized to a greater degree than in the prior art. In fact, the stick shaft can be made almost inflexible at the grip of the player's lower hand, whereby the stickends obviously bend more than in the prior art, and the stick shaft acts as a bow.
However, in practice the stick shaft is stiffenPd only so much that the deflPction of the stick shaft is as constant as possible over the entire length of the shaft.
When the puck leaves the blade, the spring-like shaft effectively converts the energy used for bowing the shaft into the translational energy of the puck, thusimparting maximum possible initial speed for the puck. The flexible part of the stick shaft becomes longer owing to the more homogeneous distribution of the shaft dPflectinn over its entire length, whereby its total permissible ~eflP~ctinn becomes larger. Though the shaft is deci~n~Pd for a nonconstant stiffness~ its fabrication cost will not be appreciably higher than that of a conventional stick.
The external limencions and outlook of the stick can be kept i~lPnti~l to that of the prior-art sticks, thus obviating the need for the players to spend time for getting accustomed with the novel stick shaft, whereby the acceptance threshold for the novel stick will be low.
In the following the invention will be PY~minPd in more detail with reference tothe ~tt~hed drawing, in which:
WO 95/U1820 21~ ~i 6 9 3 PCT/~94/00318 Figure l is a side view of an embodiment of the ice-hockey stick according to the invention shown with the stick reinforcements;
Figure 2 is a view of the stick illustrated in Fig. l shown from the direction of the stick blade;
Figure 3 is a cross section of the stick shaft; and Figure 4 is an assembly diagram for the different elements of the stick shaft 0 according to the invention.
The stick shaft can be fabricated starting from a core 3 of the stick made by, e.g., gluing from wood or plywood, and then applying the reinforcement plies onto the core by gluing. A suitable thickn~s for the core is approx. 17 mm, since the target thickn~s for a fini~h~l shaft is 20 mm with a rectangular cross section of approx. 20 mm by 30 mm. Onto the shaft blank thus fabricated is next 1z~mins~ted by gluing a reinforcement part 4, 5 comprising a center part as wide as the shaft l and wing parts linearly tapering from the center part. The length ofthe center part 4 is 200 - 300 mm, and the wing parts 5 are desiFnPA so taperingthat their total length from the end of the center part to the tip of the wing-part is 200 - 300 mm. The reinforcement is glued onto the shaft blank l so that its center 4 is coincident with the grip position of the player's lower hand. In practice the center of a reinforcement in a stick of 1400 mm length is placed toapprox. 700 mm from the heel joint between the blade 2 and the shaft l. The location of the reinforcement center point may, and in fact, should be aligned exactly to the normal grip point of each individual player. After the gluing step of the reinforcement 4, S, comp1ern~nt~ry pieces 6, 7 with a thickness id~ntic~1 tothat of the reinforcern~nt~ are l~min~ted to the stick shaft ends, whereby the complementary pieces must be de~igned to have a forked end complementary to the shape of the tip 5 of the reinforcement~ 4, 5. Now the shaft l is brought to a WO 95/01820 PCT/~94/00318 ~
21~
constant thickness permitting an optional, conventional reinforcement ply and a top ply 8 to be glued onto it.
The thickness of the reinforcement is approx. 0.5 - 1 mm and the reinforcement iS applied at least to the front side of the shaft 1, that is, on that side of the stick where the blade 2 is concave. If a stiffer shaft 1 is desirable, the reinforcement can be applied to both sides of the shaft 1. The material of the reinforcement part 4, 5 can be, e.g., glass fiber or carbon fiber or any other reinforcement material offering sufflcient stiffness ~rope~Lies. The complementary pieces 6, 7 to the 0 reinforcement are advantageously of the same material as the stick shaft, whilst their material selection is non~çnti~l to the function of the shaft 1.
With reference to the embo-limPnt~ str~t~i in Figs. 1 - 4, the reinforcement 4, 5 is shuttle-shaped in the side view, and its both wing parts 5 are triangularly tapered to sharp tips. The shape of the wing parts and thus the entire shape of reinforcements can be varied in a wide range. However, it is es~e~ to provide a sllffi~iently monotonous stiffnP~s change along the length of the stick shaft to avoid the occurrence of an abrupt stiffne~ discontinuity at which the shaft might break under load. The tips of the reinforcement~ can ~ltçrn~tively be forked, for example, whereby the tips of the r~inforcç.--ent~ and their complem~nt~ry pieceswill have mirrored shapes to those shown in the ~ gr~m~. The gradual change of the stick cross section may also be realized advantageously so that, e.g., the thickness of the reinforcement gr~ lly tapers off toward the ends of the stick shaft, whereby the reinforcement can have a constant width over its entire length.
Obviously, the shape design of the reinforcement can be implemented in a plurali-ty of manners, and a separ~le feinrol~e,-,ent piece is not neces~rily needed in all embodiments of the invention. Sticks with composite material or aluminum shafts which are emerging on the market can be easily fabricated to have a variable stiffness in accordance with the invention. In practice this can be implemented through, e.g., varying the thickness of the shaft tube wall or the reinforcementstructure of a composite material stick. In these cases the reinforcement part is an WO 95/01820 21~ 6 6 9 9 PCT/~194/00318 integral part of the shaft material and no separate reinforcement part can be indicated. Manufacture of metal tubes having a constant external ~ meter and a varying inner diameter is known per se and these kind of tubes are used for example in bicycle frames. A composite structure offers a wide variety of 5 possibilities. Properties of a composite structure can be varied by ch~n~ing the amount or material of lein~lce~ent fibres. In a composite structure ~iimencions of the structure do not alone characterise the properties of the structure and for ex~mple, the ~exibility of a composite shaft ~lepen~lc mainly of the volume and ~ro~e.lies of the reinforcement material in a given cross section. Advantageously, the external cross-sectional ~imçncions of the stick shaft are m~int~inY~ constant over the entire length of the stick shaft, whilst in special cases also a stick with the thicker cross section at the player's grip point is feasible. However, since a variable stick shaft thickne5s may feel odd to the players, a stick with a constant cross section must be ~l~rt;ll~d.
When a conventional r~ fol~e~lent system of an ice-hockey stick is combined with the embodiment according to the invention, an extremely wide range of stickshaft characteristics in a shot situation can be re~li7~1 For the m~xim~lm control of the initial energy of the shot it is most advantageous to have a relatively stiff stick shaft which is nonflexible exactly at the grip point of the player's lowerhan~ with a gradually increasing flexibility toward the stick ends. This kind of a stick design makes the stick behave ideally and offers the highest efflciency inconverting the energy imparted by the player into the tr~ncl~tiQnal energy of the puck. Top players use today custom-made sticks, and by virtue of this invention,a flexible stick compliant with the minutes of the player's preferences can be fabricated in an uncomplicated manner. The flexibility of the stick can be made to vary, e.g., progressively or to be asymmetric relative to the grip point. For example, the flexibility of the shaft can be constant above the grip point and decrease from the grip point towards the blade.
Several different methods of striking the puck are used in the game of ice-hockey.
The highest speed for the puck is att~ined by a slap shot in which the player's lower hand holding the stick at its lower part and stick are rotated at the side of the player's body behind the body, and the puck is then shot vigorously forward 0 by rotating the body and ~imlllt~neously se-n-ling the lower hand with the stick energetically forward.
