Abstract
The present invention relates to a shaft for a hockey stick. The shaft is made up of and comprises of a combined shape of 2 straight edges and 2 curved edges which are convex and which form fit to the hands. The new stick shaft design having a blade end at the bottom and a remote end at the top. The shaft is formed of a composite or carbon fibre material which is today commonly used to produce hockey sticks, all having a hollow structure including an interior surface and exterior surface. Wood may be used but usually in the creation of hockey shafts and sticks, they are of a solid material, which does not change the physics or application involved with this invention.
Description
Description and background of the invention.
In the game of hockey, the most powerful shot a player can make is the slap shot. The most accurate shots Usually come from a wrist shot or snap shot. The player executes the shots by winding up the hockey stick and forcing it in the forward motion towards the puck introducing torsion and kinetic energy into the stick, bending it, gathering up tension which will spring back in the forward motion transferring energy to the puck, accelerating it forward. This produces a whiplash effect, in which the stick and shaft are bent backwards around a point of flexion defined by the lower hand of the player, storing potential energy, which is released when the stick and shaft unbend. It essentially acts as a bow, storing and releasing energy.
Various hockey stick shafts construction exist on the market today adapted to produce better more accurate shots. This patent on the change of the shape of the shaft can be used with any method of construction, whether carbon fibre, composite, wooden sticks or a combination thereof There is an ongoing need for improving various properties of hockey sticks, to improve the games itself, having higher scores and faster play.
Such properties inherent in hockey sticks are the strength, stiffness, flexibility, damage tolerance, temperature resistance, vibration damping and weight This patent directly relates to the power input versus the power output and includes some inherent flexibility properties during shot taking and enhances other shaft properties.
Composite and carbon fibre shafts today are generally hollow and most often made to shape with a filament winding or a wrapping process. In each type of construction, the hockey stick displays a constant stiffness throughout the length of the shaft, as such the dynamic motion of the shaft bending is dependant on the strength of the player and stiffness of the shaft.
Description of prior art As described in Canadian patents; 2508313, 2223461, 2052538 and 2158898, the hockey stick shaft is generally and has over the life of the sport of hockey been portrayed as a squared rectangle shaped stick, having 4 flat sides which are adjoining, for the length of 25/Sep/201212:02:49 PM

the shaft. These patents mentioned above are of a similar nature but do not incorporate any of the inventions in this application of a rounded hockey stick shaft which is usable by players in various ways. These prior art patents support the nature of this patent where a different shaft design may create a better shot for the player. These sticks can be manufactured from many materials such as wood, carbon fibre, and aluminum etc.
Summary of the invention In accordance with the present invention, there are provided improvements to the design of the hockey stick shaft and therefore the hockey stick. It is to provide a hockey stick having improved energy releasing characteristics during a shot with dynamic motion whether in the forward motion or backward motion of the stick.
As embodied and broadly described herein, the invention provides a shaft for a hockey stick, comprising of a longitudinal axis: comprising of materials previously listed having an inner and outer edge and front and rear sides extending along said axis and top and bottom extending along said axis. Finally a blade would be secured if needed to the designated bottom end of the shaft, hence making it into a hockey stick.
Other characteristics and features of the invention will become apparent by reference to the following description and the drawings included.
This new hockey shaft shape design changes the shape of the shaft to include some curve parts along the longitudinal axis and can be used in 2 different variations.
One part of the embodiment having the front part of the shaft curve with the bottom part of the shaft curved and the other embodiment having the front part of the shaft curved with the top part of the shaft curved. The following drawings will explain how the curved portions of the shaft are incorporated into the design of the shaft. Drawing 2a) has the back part of the shaft curved with a convex shape, and the top part of the shaft curved, extending approx 1/4 inch more expansion within the dimensions of the stick, and 2b) having the front part of the shaft curved with the bottom part of shaft curved. Both 2a and 2b are the same shaft design, 2a being 180 degrees rotated around the longitudinal axis this being part 1 of the embodiments of the patent for a new shape for hockey stick shafts. Drawing 4a and 4b are the same shaft design, 4a being 180 degrees rotated around the longitudinal axis again as in drawing 2a, and 2b, extending approx 1/4 inch more expansion within the dimensions of the stick These variations allow the player a better comfort level and feel, enabling a better mental image of the puck shot. What is important and what this patent is based on is that all variations of this design lend themselves to a more pronounced force applied due to increased area and therefore related pressures applied to the shaft, resulting in faster shot, which will be explained in the paragraph below.
Taking in account the formula P(pressure) = F(force) / A(Area), if, the force applied to the shaft remains constant but the A(Area) is varied through some form or another the P(Pressure) of the object will also vary. If the area where the force is applied is expanded and provides a larger footprint to apply the force, then less force would be needed 25/Sep/201212:02:49 PM
Patent No. CA #
resulting in the same shot. With the same pressure applied, the force exerted to move an object would be less in nature. IE:( a larger area requires less force to move an object the same distance) If F=1 and A=2 then P=.5 If F=1 and A=4 then P=.25 If F=1 and A=8 then P=.125 If Pressure(P) applied is kept the same, and Area(A) increased, then the force(F) applied must also increase accelerating the object.
P=1 X A=2 then Force =2 P=1 X A=4 then Force =4 This application of the laws of physics increases firstly the forward motion or movement of the object, increasing its speed and jump off the blade of the stick. This design has more components in it such as secondly increasing the feel of the stick in the players hands, due to its rounded nature, which is extrapolated from other forms of sticks such as golf clubs and baseball bats enabling the player to use his fingers to tell him the exact position of the shaft in his hands.
Brief description of the drawings A detailed description of the preferred embodiments of the present invention is provided herein below, by way of example only, with reference to the accompanying drawings, in which:
Figure 1 is a side view of a hockey shaft Figure 2a, and 2b. are a cross sectional view of the shaft taken at one end of the shaft.
2a being the same as 2b in the sense that it is only rotated 180 degrees along its cross sectional axis.
Figure 3 is the top level view of figure 1 from the player's perspective of looking down towards the hockey shaft during the motion of a shot taking place.
Figures 4a. and 4b. are a cross sectional view of the shaft taken at one end of the shaft. 4a being the same as 4b in the sense that it is only rotated 180 degrees along its cross sectional axis, and is a second embodiment of this present invention / patent.
Description of the preferred embodiment Figure 1 illustrates a hockey stick comprising a shaft end and a blade end.
The shaft is as long as a normal stick within rules and regulations of hockey.
The stick can be configured either with the frontal part curved as depicted in figure 2b and 4b or the rear part curved as depicted in figure 2a and 4a.
In both figure 2a. and 2b. 4a and 4b, 2 sides of the stick have not changed shape and are similar to current manufactured sticks, where they have remained a straight edge along 3/5 25/Sep/201212:02:49 PM

the longitudinal axis throughout the length of the shaft until reaching the open end where the blade would fit at which point the shaft is narrowed to fit the blade snugly into it making one complete stick with shaft and blade forming a hockey stick.
The shaft of the stick is hollow or can be filled with foam as is current manufacturing processes but this will not change the physics of the sticks performance but may change the weight slightly.
The shaft as stated in Para 2 "Background of the invention" can be made of wood (solid), or composite (hollow) material. Either way the physics applied to the shaft are the same and will result in the same outcome, an increased performance and more explosive shot from the kinetic energy being released.
Figure 2a and 2b, 4a and 4b, use the formulas listed above as a way to show that with the addition of the rounded shaft, the grip of the player is more pronounced, giving the player more surface area in which his hand is applied to the rear shaft of the stick.
Using the same amount of forward force, will result in the same amount of pressure being applied as to a normal stick but due to increased area, more pressure is created, which will then be released when the stick releases its built up kinetic energy.
This newly shaped stick has the same shape from top end to blade whether being of 2a or 2b. Near the blade end, the shaft will narrow to equate the size of the blade's neck, giving the stick a slow narrowing towards the blade end to facilitate blade insertion, ensuring adequate performance and safety, so that the stick conforms to current regulations of safety keeping the blade intact in the shaft.
Figure 3 is a top view as seen by the player during a shot whether a snap, or slap, or wrist shot. It shows the stick building up kinetic energy as a spring during the slapping of the ice, bending rearward. Once the stick and shaft contact the puck, continuing the forward momentum applied by the player, the shaft will move the puck forward eventually running out of ice and releasing the kinetic energy stored.
Figures 4a and 4b illustrate a hockey stick cross section according to a second embodiment of this present invention.
This newly shaped stick has the same shape from top end to blade whether being of 4a or 4b. Near the blade end, the shaft will narrow to equate the size of the blade's neck, giving the stick a slow narrowing towards the blade end to facilitate blade insertion, ensuring adequate performance and safety, so that the stick conforms to current regulations of safety keeping the blade intact in the shaft.
The above description of the preferred shaft shape changes should not be interpreted in a limiting manner since other variations, modification and refinements such as size changes within the spirit and scope of the invention are possible. This invention is to introduce a different shape to a hockey stick shaft to improve shot characteristics, such as power inserted and power exerted for the player.
