Description
208301~
~oc~Y ~C~
Field of the Invention This invention relates to the game of hockey and in particular to a hockey puck for use primarily by young and developing players of the game, but not limited thereto.
Bac~ground of the Invention A standard, regulation size hockey puck is fairly heavy and unwieldly for young boys and girls trying to develop their skills at the game and, indeed, for some of the expanding numbers of senior citizens who want to continue to play hockey at a less serious level. The weight of a regulation puck can, to some extent, be a limiting factor on a young player's ability to develop stick handling and shooting skills. Most of the equipment utilized by younger hockey players, skates, pads, sticks and helmets are all available in sizes specific to the physical stature of the younger players, but they still have to deal with a hockey puck of regulation size and weight. While the physical size of the puck is not in itself a problem to the younger and developing players, the weight of the regulation puck often is a problem.
Several patents have been obtained on pucks that have been altered in physical size or by adding other materials to a puck to render them more easily handled on supporting surfaces whether it be ice, asphalt, concrete or the like. Examples of these patents can be .~
- 208~01~
found in Canadian Patent 935,453 White of October 16, 1973 in which a puck has been centre bored to receive a carriage bolt-type of arrangement ~n a male and female connection so as to provide additional, low friction surfaces for gliding of the puck.
Canadian Patent 959,872 Beauchamp et al, December 24, 1974 shows a hockey puck having a portion of one surface which has been relieved for the purpose of inserting extra material on that surface.
A floor hockey puck is shown in Canadian Patent 1,209,165 of August 5, 1986 in which the apparatus is formed of a wound or coiled substance.
Lastly, Canadian application 2,046,957 shows a hockey puck having a series of rollers integrally formed therein to provide an easy rolling surface to the puck.
All of these prior art arrangements add weight and complexity to a hockey puck whether it is of regulation size and material or not.
8ummary of tbe Invent~on The purpose of the present invention is to provide a hockey puck of conventional physical dimensions with a diameter and width of a regulation size puck but having a substantial reduction in weight. While a hockey puck according to the invention can be made of various resilient materials, the use of vulcanized rubber, similar to a regulation puck, is preferred so that the NfeelN of the puck on the stick of a developing player is not completely lost. The weight reduction of the puck according to the invention compared to a regulation puck is obtained by forming the body of the puck with a central recess on at least one side of the body or, in a preferred embodiment, 3 208~01S
with a central aperture, the diameter of which can vary depending on the developmental needs, and ages of the players using it. For example, the diameter of the central aperture or recess can be approximately one third of the diameter of the puck. The recesses or the aperture has a specific form in that it tapers from approximately the middle of the thickness of the puck towards the upper and lower surfaces thereof. The degree of the taper again can vary depending upon the developmental needs of the players.
Because a puck according to the invention is substantially lighter than a regulation puck, younger players, for example between the ages of five and eight, can realize substantial success in raising the puck off the ice and shooting it faster than through the use of a standard puck. Moreover, because it is lighter the young player has fewer problems in developing stick handling, passing and shooting skills.
The puck according to the invention travels somewhat faster on the ice than a standard puck due to the fact that the central aperture or recess reduces surface contact between the lower surface of the puck and the ice and this allows the younger player to skate somewhat quicker, moving the puck along and reducing situations where the player over-skates the puck.
Through the use of a lighter and more responsive hockey puck, younger, developing players can begin to enjoy the game at an earlier stage and they are thus encouraged to try new movements with such a puck in shooting, passing and stick handling. Increased confidence of the player can be a result.
The aperture or recess in the puck can also be used to develop skills necessary for puck control by having the players turn their sticks upside down and inserting the butt end of the stick into the central aperture and rehearsing puck control movements in a manner similar to that used in the game of ringette.
It has been found in ceveral training teste using a puck according to the invention that young player6 would choo~e to train with the puck of thie invention rather than the standard puck and their enthusiasm in a training or game ses6ion lasts noticeably longer as the puck according to the invention is more reflective of their developmental needs and skills and they do not tire as quickly as when they are using a ~tandard puck.
A hockey puck according to the invention also has some safety benefits when used with younger, developing players and, to some extent, with senior players.
While it is within the realm of the invention to use a softer more flexible material than the standard vulcanized rubber used in a regulation puck, even the use of the regulation material, if formed in a puck according to the invention, provides a lighter object from the point of view of being handled by goaltenders or if a player is struck by the puck.
The recess or tapered aperture in the puck of the invention noticeably reduces the diametrical stiffness of a regulation puck. This stiffness reduction will vary according to the diameter of the aperture or the extent of the recess and this stiffness is most notable when the puck is subjected to a radial load or impact, for example when subjected to a slap shot by a player or striking a goaltender either on the goaltender's equipment or on a less protected part of the goaltender's body.
In a regulation puck, deformation is typified by very localized radial deflection and bulging at the edges of the standard puck adjacent and normal to the applied load. When subjected to the same load, a puck according to the invention deflects substantially more s in a radial direction to change its overall profile from a circular to an elliptical shape. An increase in the puck'~ ability to deflect and deform under a given load or impact signifies that more energy is being absorbed, deflected and dissipated by the puck according to the invention rather than being transmitted to an object or person such as a goaltender or defender. Thus, an added margin of safety for players and reduced harsh impacts on usual protective gear and equipment is realized.
According to a broad aspect, the invention relates to a hockey puck comprising a circular body formed of resilient material with flat, parallel upper and lower surfaces and a central aperture extending through the body of the puck. In a preferred form, the central aperture tapers outwardly from approximately the midpoint of the thickness of the puck towards the upper and lower surfaces.
Brief Description of the Drawin~s The invention is illustrated by way of example in the accompanying drawings in which:
FIGURE 1 is a plan view of a hockey puck according to the invention;
FIGURE 2 is a sectional view of the puck taken along the lines 2-2 of Figure 1;
FIGURE 3 is a plan view of the puck according to the invention showing some deformation under impact;
and FIGURES 4, 5 and 6 are sectional views of a further embodiment of the invention.
Detailed DescriPt~on of t~e Drawings Referring to Figures 1-3 of the drawings, a hockey 6 208~015 puck 10 according to a preferred embodiment of the invention is illustrated and is formed by a ~uitable resilient material such as vulcanized rubber. The puck has a circular body 12 with flat, parallel upper and lower surfaces 14, 16 and a cylindrical outer wall 18 which is normal to the upper and lower surfaces. The body can be of regulation size i.e. approximately 3 n in diameter and lH in thickness.
A centrally located aperture 20 is provided in the puck and extends completely through the body thereof as shown in Figure 2. The configuration of the aperture can be cylindrical, in which case the wall of the aperture is straight and parallel with the outer rim or wall of the puck. However, in a preferred form, the wall of the aperture 20 tapers outwardly as at 22 from the middle 24 of the thickness of the body of the puck towards the upper surface 14 thereof and it also tapers as at 26 from the middle thickness 24 towards the lower surface 16 thereof. As shown in Figure 2, this results in the upper and lower halves of the body each having a frusto-conical recess joined to a similar recess on the other half of the body.
The tapered wall aperture 20 provides a reduced diametrical stiffness to the puck body when the puck is subjected to radial impact. As shown in Figure 3, when the puck 10 is struck by the blade 28 of a hockey stick, the body of the puck tends to deform into an oval or elliptical configuration as seen in plan view, that portion of the body adjacent the stick absorbing a substantial part of the load.
As described earlier, the diameter of the aperture and the degree of the taper can be varied to suit the age of the hockey players using the puck.
Figures 4, 5 and 6 are cross-sectional views of 208~01~
other forms which the present invention may take.
Figure 4 discloses an embodiment in which a puck 30 has the circular body 32 with the flat parallel upper and lower surfaces 34 and 36 respectively and the cylindrical outer wall 38. Instead of having two, meeting frusto-conical apertures resulting in a clear aperture through the puck as in Figures 1, 2 and 3, in this embodiment a single recess 40 is formed in one surface only and, while having an outwardly tapering side wall 42, the recess does not continue through the body of the puck but, instead, a thin portion 44 remains on the lower surface to render that surface completely planar.
In the embodiment of Figure 5, the puck 46 has a pair of frusto-conical recesses 48 and 50 in the upper and lower surfaces respectively of the puck leaving a thin central membrane 52 across the center of the body instead of having a through aperture therein.
Lastly, in the embodiment of Figure 6, the puck 54 again has a pair of cylindrical recesses 56, 58 in the upper and lower surfaces respectively thereof having their wall surfaces parallel with the outer rim of the puck and leaving a thin central membrane 60 in the center of the body of the puck.
These embodiments of the invention utilizing one or more recesses in the body of the puck rather than a through aperture, provides a product of somewhat increased stiffness with respect to the embodiment of Figures 1, 2 and 3. ObViously, the thickness of the membranes 52 or 60, would be a factor in determining the thickness or impact resistance of the puck.
While the invention has been described in connection with a specific embodiment thereof and in a specific use, various modifications thereof will occur 8 2o83ol5 to those skilled in the art without departing from the spirit and scope of the invention as set forth in the appended claims.
The terms and expressions which have been employed in this specification are used as terms of description and not of limitations, and there is no intention in the use of such terms and expressions to exclude any equivalents of the features shown and described or portions thereof, but it is recognized that various modifications are possible within the scope of the invention claims.
