Abstract
A sporting shaft, kits, and corresponding methods are described. The shaft has an elongated shaft section, and a paddle section. The paddle section can enter into contact with an object, and has an upper edge and a lower edge. The junction of the paddle and shaft sections forms a gripping surface. The shaft also has an elongated shaft protrusion which projects from the shaft section and can increase the shaft width. The shaft protrusion extends along the shaft section. The shaft also has a paddle protrusion disposed adjacent to the gripping surface and projecting from at least one of the upper and lower edges of the paddle section. The paddle protrusion can increase an edge thickness the upper or lower edges so as to substantially adapt the at least one edge to a natural contour of the hand when gripping the shaft.
Description
SPORTING SHAFT AND CORRESPONDING KIT AND METHOD
Field of the invention:
The present invention relates to sporting shafts, such as hockey or lacrosse goalie sticks, for example. More particularly, the present disclosure relates to a sporting shaft with improved ergonomic features, thereby enhancing the grip of the hand of a user on the shaft.
Background of the invention:
Sporting shafts are known in the art. In the field of ice hockey, as but one example of a sport in which such shafts are used, sporting shafts can include ice hockey sticks, which are used by both position players and by goaltenders (i.e.
"goalies").
One example of such an ice hockey stick includes a goalie stick. Conventional goalie sticks have a known shape which consists of an elongated hand-held upper portion, commonly referred to as the "shaft", which joins to a lower deflection portion.
This deflection portion is connected to the upper portion and is commonly referred to as the "paddle" of the goalie-stick. The paddle is typically wider than the upper portion, and thinner on the outer edges of the paddle than the upper portion.
The paddle ends in a blade, which can contact the playing surface so as to manipulate an object such as a puck.
During use, the goalie typically holds the goalie stick in one hand. The hand is typically covered with a goalie blocker. The goalie's other hand is typically used to catch pucks with the aid of a goalie glove. Typically, the goalie will hold the goalie stick on the shaft at the junction of the shaft and the paddle. It is at this point that the goalie exerts the necessary force transfer from her/his hand to the goalie stick in

Sporting shafts are known in the art. In the field of ice hockey, as but one example of a sport in which such shafts are used, sporting shafts can include ice hockey sticks, which are used by both position players and by goaltenders (i.e.

One example of such an ice hockey stick includes a goalie stick. Conventional goalie sticks have a known shape which consists of an elongated hand-held upper portion, commonly referred to as the "shaft", which joins to a lower deflection portion.
This deflection portion is connected to the upper portion and is commonly referred to as the "paddle" of the goalie-stick. The paddle is typically wider than the upper portion, and thinner on the outer edges of the paddle than the upper portion.
The paddle ends in a blade, which can contact the playing surface so as to manipulate an object such as a puck.
During use, the goalie typically holds the goalie stick in one hand. The hand is typically covered with a goalie blocker. The goalie's other hand is typically used to catch pucks with the aid of a goalie glove. Typically, the goalie will hold the goalie stick on the shaft at the junction of the shaft and the paddle. It is at this point that the goalie exerts the necessary force transfer from her/his hand to the goalie stick in
2 order to control and operate the goalie stick. When the hand is in such a location, and as shown in Figure 1, typically three of the fingers of the hand ¨ the pinkie, ring, and middle fingers ¨ are wrapped around the shaft of the goalie stick. The index finger and the thumb extend over opposite sides of the paddle, which can help in gripping the goalie stick and in providing rotational stability. Of course, it is possible for the goalie to place her/his hands on any portion of the goalie stick, and to manipulate the paddle portion from such a position.
The following prior art documents relate to hockey or goalie sticks.
US patent 5,456,463 issued to DOLAN et al. on October 10, 1995 relates to a hockey stick with an ergonomic grip. The goalie hockey stick includes a blade and a shaft joined at a heel, the shaft including a widened shaft portion and a narrow handle portion. An ergonomic handgrip is formed between the widened shaft portion and the handle portion.
US patent 7,282,001 B2 issued to PONZINI on October 16, 2007 relates to a pressure grip for a goalie hockey stick. The pressure grip includes a support boot and a hand grip. The support boot includes a paddle portion and a handle portion.

2,172,850; CA 2,198,272; CA 2,227,492; and CA 2,753,935.
Conventional goalie sticks have some of the following disadvantages.
The shafts of known goalie sticks are often too small or too thin to accommodate the forces applied to them. Indeed, many convention goalie stick shafts , , ,
3 are identical to the shafts of position player hockey sticks, which have different force and operational requirements. A cross-section of a typical shaft can have approximately rectangular dimensions of 1 1/8" X 3/4". This dimensional limitation makes it difficult for a goalie to establish a suitably strong grip on the shaft with her/his pinkie, ring and middle fingers.
Another disadvantage relates to users having average or above-average finger/hand sizes. For these users, the ability to get a strong grip on the shaft is limited because the fingers contact the palm as they wrap around the shaft of the goalie stick, thereby preventing the finger ends from fully engaging the shaft. This phenomenon is shown in Figures 1 and 2. This phenomenon occurs irrespective of the amount of squeeze force applied by the hand because the circumference and/or outer dimensions of the shaft are relatively small.
Yet another disadvantage relates to the paddle of the goalie stick. The shape of the paddle does not often allow for an effective grip of the paddle by the index finger and thumb on the upper edge of the paddle. The paddle is typically thickest midway through its faces, having an approximate thickness of 1/411, and tapers off to a rounded edge on the upper and lower edges of the paddle faces. This tapering off of the face, especially on the upper edge of the paddle, does not follow the natural contour of the index finger and the thumb when gripping the paddle, an example of which is shown in Figure 3. This disconformity can result in limited surface contact between the paddle and the index finger/thumb, as shown in Figure 4. This, in turn, results in grip instability for a goalie when trying to counter the rotational torque which can affect the goalie stick.
Yet another disadvantage relates to the taper of the paddle on its lower edge.
As shown in Figure 5, such a taper can often result in an ineffective point of contact between the intermediate and distal ends of the index finger and the lower edge of the paddle. This lower edge of the paddle may not provide enough surface area
Another disadvantage relates to users having average or above-average finger/hand sizes. For these users, the ability to get a strong grip on the shaft is limited because the fingers contact the palm as they wrap around the shaft of the goalie stick, thereby preventing the finger ends from fully engaging the shaft. This phenomenon is shown in Figures 1 and 2. This phenomenon occurs irrespective of the amount of squeeze force applied by the hand because the circumference and/or outer dimensions of the shaft are relatively small.

This disconformity can result in limited surface contact between the paddle and the index finger/thumb, as shown in Figure 4. This, in turn, results in grip instability for a goalie when trying to counter the rotational torque which can affect the goalie stick.
Yet another disadvantage relates to the taper of the paddle on its lower edge.
As shown in Figure 5, such a taper can often result in an ineffective point of contact between the intermediate and distal ends of the index finger and the lower edge of the paddle. This lower edge of the paddle may not provide enough surface area
4 against which the index finger may apply force, thereby reducing the ability of the user to obtain a suitable grip of the goalie stick. This can lead to grip instability for a goalie when trying to counter the rotational torque which can affect the goalie stick.

This improved grip can lead, in turn, to an improved performance because the
12 user is better able to manipulate the shaft in order to stop, intercept, deflect, and/or play an object, for example.
Referring to Figure 6, the shaft 20 includes an elongated shaft section 30.
The shaft section 30 can be any rectangular or differently-shaped bar, handle, pole, stem, etc. which can be held, gripped, handled, etc. by the user. The shaft section 30 is elongated, in that it extends over a certain length so as to provide a suitable handling surface for the user, and so as to provide a suitable moment arm when handling objects (i.e. a puck, a ball, a ring, etc.) located away from the shaft section 30. The user can slide their hand up and down the shaft section 30 as required, such as for example to bring the hand closer to the paddle section described below.
The shaft section 30 has a certain geometry with dimensions, one of which is the shaft width Ws. In order to better understand the components and features as described herein, it may be helpful to establish a frame of reference, which may be best understood in relation to one example of a shaft 20 - a goalie stick. The term "width" as used herein refers to a distance between two points, where the two points are connected by a line which is roughly or substantially parallel to the orientation of the blade of the goalie stick. For example, if the goalie stick were laid against the floor on its "back", with the blade pointing into the air, the shaft width Ws would be a distance between two points along the shaft section 30, the first point being located on the part of the shaft section 30 nearest the floor, and the second point being located on the part of the shaft section 30 furthest away from the floor.
Similarly, the term "thickness" as used herein refers to a distance between two points, where the two points are connected by a line which is roughly or substantially perpendicular to the orientation of the blade of the goalie stick (i.e. perpendicular to the direction of the "width"). Furthermore, the terms "upper" and "lower" as used herein refer to surfaces or edges of the shaft section 30 or paddle section. An "upper surface" of the shaft section 30 is a face of the shaft section 30 which is closest to the blade of the goalie stick when it is laid on its back. An "upper edge" is an edge of the paddle section
Referring to Figure 6, the shaft 20 includes an elongated shaft section 30.
The shaft section 30 can be any rectangular or differently-shaped bar, handle, pole, stem, etc. which can be held, gripped, handled, etc. by the user. The shaft section 30 is elongated, in that it extends over a certain length so as to provide a suitable handling surface for the user, and so as to provide a suitable moment arm when handling objects (i.e. a puck, a ball, a ring, etc.) located away from the shaft section 30. The user can slide their hand up and down the shaft section 30 as required, such as for example to bring the hand closer to the paddle section described below.
The shaft section 30 has a certain geometry with dimensions, one of which is the shaft width Ws. In order to better understand the components and features as described herein, it may be helpful to establish a frame of reference, which may be best understood in relation to one example of a shaft 20 - a goalie stick. The term "width" as used herein refers to a distance between two points, where the two points are connected by a line which is roughly or substantially parallel to the orientation of the blade of the goalie stick. For example, if the goalie stick were laid against the floor on its "back", with the blade pointing into the air, the shaft width Ws would be a distance between two points along the shaft section 30, the first point being located on the part of the shaft section 30 nearest the floor, and the second point being located on the part of the shaft section 30 furthest away from the floor.
Similarly, the term "thickness" as used herein refers to a distance between two points, where the two points are connected by a line which is roughly or substantially perpendicular to the orientation of the blade of the goalie stick (i.e. perpendicular to the direction of the "width"). Furthermore, the terms "upper" and "lower" as used herein refer to surfaces or edges of the shaft section 30 or paddle section. An "upper surface" of the shaft section 30 is a face of the shaft section 30 which is closest to the blade of the goalie stick when it is laid on its back. An "upper edge" is an edge of the paddle section
13 which is closest to the blade of the goalie stick when it is laid on its back.
It is understood that a "lower surface" of the shaft section 30 and a "lower edge"
of the paddle section are opposed to the upper surface and upper edge.
Still referring to Figure 6, the shaft 20 also includes a paddle section 40.
The paddle section 40 can be wider than the shaft section 30, thereby providing a deflection surface to be used to deflect incoming shots of a ball, puck, etc.
The paddle section 40 can also be used to apply a force to an object. The paddle section 40 thus allows a user to enter into contact with an object. The paddle section 40 has an upper edge 42 and an opposed lower edge 44. The edges 42,44 can span the length of the paddle section 40 or only a part thereof, and may also be rounded.
The paddle section 40 can have a paddle thickness Tp, which can be less than a shaft thickness T. In some optional configurations, the paddle thickness Tp varies along the faces of the paddle section 40, or along a paddle width Wp, such that the paddle thickness Tp is greater at a center of the paddle section 40 than at the edges 42,44 (i.e. edge thickness Te). Thus, the paddle thickness Tp can taper off towards the edges 42,44, such that the paddle thickness Tp is substantially equal to the edge thickness Te at the edges 42,44. At the center of the paddle section 40, the paddle thickness Tp can be about %".
The paddle section 40 joins to the shaft section 30, and this junction forms a gripping surface 22. The gripping surface 22 can be any interface, junction, meeting area, confluence, etc. formed by the junction of the shaft and paddle sections 30,40 which allows a user to grip the shaft 20 so as to better manipulate the shaft 20 and/or paddle section 40. As such, the gripping surface 22 can take on any suitable shape, form, contour, etc. that would allow such functionality. Considering now an optional configuration where the shaft 20 is a goalie stick, the gripping surface 22 can be the part of the goalie stick where the shaft section 30 widens into the paddle section 40.
In such an example, when the user wants to exert more force and/or control over the
It is understood that a "lower surface" of the shaft section 30 and a "lower edge"
of the paddle section are opposed to the upper surface and upper edge.

Thus, the paddle thickness Tp can taper off towards the edges 42,44, such that the paddle thickness Tp is substantially equal to the edge thickness Te at the edges 42,44. At the center of the paddle section 40, the paddle thickness Tp can be about %".
The paddle section 40 joins to the shaft section 30, and this junction forms a gripping surface 22. The gripping surface 22 can be any interface, junction, meeting area, confluence, etc. formed by the junction of the shaft and paddle sections 30,40 which allows a user to grip the shaft 20 so as to better manipulate the shaft 20 and/or paddle section 40. As such, the gripping surface 22 can take on any suitable shape, form, contour, etc. that would allow such functionality. Considering now an optional configuration where the shaft 20 is a goalie stick, the gripping surface 22 can be the part of the goalie stick where the shaft section 30 widens into the paddle section 40.
In such an example, when the user wants to exert more force and/or control over the
14 goalie stick and/or the paddle section 40, the user will often slide their hand down the shaft section 30 towards the shaft section 40, and the gripping surface 22 can be the part of the goalie stick on which the user's hand comes to a rest and from where the user manipulates the goalie stick and/or paddle section 40. In most situations, the user's hand is located on the gripping surface 22.
Referring to Figure 7, the shaft 20 also includes an elongated shaft protrusion 50. The shaft protrusion 50 can be any bulge, protuberance, bump, ridge, swell, etc.
which projects away from the shaft section 30. The term "projecting" as used herein can mean that the shaft protrusion 50 is a geometry defined by an extension of material away from the shaft section 30 to a certain distance. Optionally, the shaft protrusion 50 projects from the shaft section 30 to a distance of about 3/8".
Further optionally, the shaft protrusion 50 projects from an upper surface of the shaft section 30. By extending away from an upper surface (i.e. a surface on the blade side of a goalie stick, for example), the shaft protrusion 50 can better match the natural contour of the hand closed around it, thus improving grip and control of the shaft 20.
Furthermore, such a position prevents the shaft protrusion 50 from interfering with the lower surface of the shaft 20 when it is laid upon the ground, for example.
The shaft protrusion 50 also extends along a length of the shaft section 30, in a direction beginning at the gripping surface 22 and extending away from it until the shaft protrusion 50 ends at a shaft protrusion end 52. In most configurations, but not necessarily all, the shaft protrusion 50 will project from, and extend along, an upper surface of the shaft section 30 (i.e. the part of the shaft section 30 closest to the blade of a goalie stick, for example). The length of the shaft protrusion 50 along the shaft section 30 can vary, and can depend on numerous factors such as the length of the shaft section 30, the amount of projection needed for a given sport and/or activity, etc.
Indeed, the shaft protrusion 50 may taper back to, or slant towards, the shaft section at the shaft protrusion end 52. This gradual transition to the shaft protrusion 50, 30 from the point of view of a user sliding their hand along the shaft section 30 toward =
the shaft protrusion 50 and/or gripping surface 22, can allow the hand to more easily adapt and grip the shaft protrusion 50, and to more easily transition from their grip on the shaft section 30 to a grip on the paddle section 40 and/or gripping surface 22. In some optional configurations, the shaft protrusion 50 has a shaft protrusion thickness T. This shaft protrusion thickness Tsp can be equal to the shaft thickness Ts so as to provide uniformity of appearance and use, among other reasons.
The shaft protrusion 50 thus defines a shape, which can take any profile, form, contour, etc. Some examples of these shapes include substantially rectangular, wave-like, rounded, dimpled, etc. In one possible configuration, the shaft protrusion 50 is a separate component from the shaft 20, which can be affixed and removed to the shaft section 30 as desired by an appropriate fastener (screws, adhesive, nails, hook-and-loop, press fit, etc.). Alternatively, the shaft protrusion 50 is an integral component of the shaft section 30 and/or shaft 20, and can thus be bonded or joined

which projects away from the shaft section 30.

By extending away from an upper surface (i.e. a surface on the blade side of a goalie stick, for example), the shaft protrusion 50 can better match the natural contour of the hand closed around it, thus improving grip and control of the shaft 20.
Furthermore, such a position prevents the shaft protrusion 50 from interfering with the lower surface of the shaft 20 when it is laid upon the ground, for example.
The shaft protrusion 50 also extends along a length of the shaft section 30, in a direction beginning at the gripping surface 22 and extending away from it until the shaft protrusion 50 ends at a shaft protrusion end 52. In most configurations, but not necessarily all, the shaft protrusion 50 will project from, and extend along, an upper surface of the shaft section 30 (i.e. the part of the shaft section 30 closest to the blade of a goalie stick, for example).

the shaft protrusion 50 and/or gripping surface 22, can allow the hand to more easily adapt and grip the shaft protrusion 50, and to more easily transition from their grip on the shaft section 30 to a grip on the paddle section 40 and/or gripping surface 22. In some optional configurations, the shaft protrusion 50 has a shaft protrusion thickness T. This shaft protrusion thickness Tsp can be equal to the shaft thickness Ts so as to provide uniformity of appearance and use, among other reasons.
The shaft protrusion 50 thus defines a shape, which can take any profile, form, contour, etc. Some examples of these shapes include substantially rectangular, wave-like, rounded, dimpled, etc. In one possible configuration, the shaft protrusion 50 is a separate component from the shaft 20, which can be affixed and removed to the shaft section 30 as desired by an appropriate fastener (screws, adhesive, nails, hook-and-loop, press fit, etc.). Alternatively, the shaft protrusion 50 is an integral component of the shaft section 30 and/or shaft 20, and can thus be bonded or joined
15 using any suitable technique. Furthermore, the shaft protrusion 50 could be part of the construction of the shaft 20. For example, when the shaft 20 is made of wood, the shaft protrusion 50 could simply be a widening of the wood shaft 20 at a suitable location.
The shaft protrusion 50 is positioned, shaped, and sized to increase the shaft width Ws, thereby enhancing a grip of the hand of the user on the shaft section 30 and/or shaft protrusion 50. The expression "increase the shaft width Ws" can mean that the shaft width Ws has a certain value, and that this value is increased in the area of the shaft section 30 in which the shaft protrusion 50 is placed. Such an increase in shaft width Ws can advantageously allow for the user to better grip the shaft 20.
Figure 8 provides an example of this better grip. Figure 8 shows a hand 70 of a user holding and/or gripping the shaft protrusion 50 near the gripping surface 22.
For the sake of clarity, the hand 70 is shown without a glove, although it is understood that the hand 70 may be gloved and that such a gloved hand 70 is within the scope of the present disclosure. As shown, the middle finger 74, the ring finger 76, and the pinkie

Such an increase in shaft width Ws can advantageously allow for the user to better grip the shaft 20.
Figure 8 provides an example of this better grip. Figure 8 shows a hand 70 of a user holding and/or gripping the shaft protrusion 50 near the gripping surface 22.
For the sake of clarity, the hand 70 is shown without a glove, although it is understood that the hand 70 may be gloved and that such a gloved hand 70 is within the scope of the present disclosure. As shown, the middle finger 74, the ring finger 76, and the pinkie
16 finger 78 can wrap around the shaft protrusion 50 so as to grip it. The increased shaft width Ws can advantageously prevent the fingertips of these fingers 74,76,78 from wrapping about the shaft protrusion 50 and abutting against the palm of the hand 70.
In known shafts, when the fingertips abut against the palm, the user's grip of the shaft can weaken because some of the force applied by the fingers and/or fingertips is used to push against the palm, and thus cannot be applied to the shaft.
Alternatively, if the user can apply almost all this force against the shaft and/or shaft section, a much better grip may be secured. It is thus appreciated that a shaft 20 with a larger cross-sectional area (i.e. because it is wider), such as the one herein described, can allow for a better grip to be applied by the user by allowing the fingers 74,76,78 to wrap completely around the outer circumference of the shaft 20 while minimizing their contact with the palm. This can allow the user to better resist forces (i.e. torsional, impactful, discrete, etc.) that may be applied against the shaft 20.
Considering now the example of the shaft 20 being a goalie stick, the shaft protrusion 50 further advantageously does not interfere with the hand of the goalie being able to lay the lower edge 44 of the paddle section 40 flat against the ice, a manoeuvre known as "paddle down".
Referring to Figures 9 and 10, the shaft 20 also includes a paddle protrusion 60. The paddle protrusion 60 is located adjacent to and/or near the gripping surface 22. One possible example of such a location can be the point on the paddle section 40 forming part of the gripping surface 22. Another possible location can be below the gripping surface 22 on the paddle section 40, or above the gripping surface 22 below the shaft section 30. The paddle protrusion 60 can also be located directly on the gripping surface 22 as well, and many other such locations are possible.
As with the shaft protrusion discussed above, the paddle protrusion 60 can be any bulge, protuberance, bump, ridge, well, etc. which projects from one of, or both of, the upper edge 42 or lower edge 44 of the paddle section 40. Similarly to the shaft
In known shafts, when the fingertips abut against the palm, the user's grip of the shaft can weaken because some of the force applied by the fingers and/or fingertips is used to push against the palm, and thus cannot be applied to the shaft.
Alternatively, if the user can apply almost all this force against the shaft and/or shaft section, a much better grip may be secured.

One possible example of such a location can be the point on the paddle section 40 forming part of the gripping surface 22. Another possible location can be below the gripping surface 22 on the paddle section 40, or above the gripping surface 22 below the shaft section 30. The paddle protrusion 60 can also be located directly on the gripping surface 22 as well, and many other such locations are possible.
As with the shaft protrusion discussed above, the paddle protrusion 60 can be any bulge, protuberance, bump, ridge, well, etc. which projects from one of, or both of, the upper edge 42 or lower edge 44 of the paddle section 40. Similarly to the shaft
17 protrusion, the term "projecting" as used to describe the paddle protrusion 60 can mean that the paddle protrusion 60 extends away from one of, or both of, the edges 42,44. The direction this extension can follow may vary. For example, the paddle protrusion 60 can extend away from the faces on both sides of the paddle section 40 (i.e. in a direction parallel of the "thickness", as explained above), so as to "widen" the edges 42,44 of the paddle in order to better fit the natural contours of the hand when gripping the stick. Alternatively, the paddle protrusion 60 can extend in a direction parallel to the "width". In yet another possible configuration, the paddle protrusion 60 can extend at an angle to the edges 42,44. It is thus apparent that any direction of projection is possible provided that the paddle protrusion 60 can better match the natural contour of the hand closed around it, thus improving grip and control of the shaft 20, as further explained below.
The paddle protrusion 60 thus defines a shape, which like the shaft protrusion, can take any profile, form, contour, etc. Some examples of these shapes include substantially rectangular, wave-like, rounded, dimpled, triangular, tapered, trapezoidal, etc. In one possible configuration, the paddle protrusion 60 is a separate component from the shaft 20, which can be affixed and removed to the paddle section 40 and/or gripping surface 22 as desired by an appropriate fastener (screws, adhesive, nails, hook-and-loop, press fit, etc.). Alternatively, the paddle protrusion 60 is an integral component of the paddle section 40 and/or shaft 20, and can thus be bonded or joined using any suitable technique. Furthermore, the paddle protrusion 60 could be part of the construction of the shaft 20. For example, when the shaft 20 is made of wood or another material, the paddle protrusion 60 could simply be a thickening of the wood shaft 20 and/or paddle section 40 at a suitable location.
Optionally, the paddle protrusion 60 can have a profile which decreases in thickness along at least one of the upper and lower edges 42,44, in a direction spanning from the gripping surface 22 to a paddle protrusion end 62. The paddle protrusion 60 may thus taper back to the edge thickness Te of the rest of the paddle section 40 at the paddle protrusion end 62. In one such configuration, the thickness of the paddle =

For example, when the shaft 20 is made of wood or another material, the paddle protrusion 60 could simply be a thickening of the wood shaft 20 and/or paddle section 40 at a suitable location.
Optionally, the paddle protrusion 60 can have a profile which decreases in thickness along at least one of the upper and lower edges 42,44, in a direction spanning from the gripping surface 22 to a paddle protrusion end 62. The paddle protrusion 60 may thus taper back to the edge thickness Te of the rest of the paddle section 40 at the paddle protrusion end 62. In one such configuration, the thickness of the paddle =
18 protrusion 60 can be its largest near the gripping surface 22, and then taper gradually back towards the paddle section 60 so as to eventually have the same thickness value as the edge thickness Te. This gradual transition to the paddle protrusion 60 may help a user to slide their hand more easily along the paddle protrusion 60 and/or paddle section 40, and may also better conform to the natural contour of the hand when gripping the shaft 20.
The paddle protrusion 60 is positioned, shaped, and sized to increase an edge thickness Te of at least one of the upper and lower edges 42,44. As with the shaft protrusion, the expression "increase an edge thickness Te" can mean that the edge thickness Te has a certain value at the edges 42,44, and that this value is increased on the edge and/or edges 42,44 on which the paddle protrusion 60 is located.
Such an increase in edge thickness Te can substantially adapt the edge 42,44 to the natural contour of the hand when it grips, or closes about, the shaft 20, thereby enhancing a grip of the hand. Optionally, the paddle protrusion 60 can define a paddle protrusion thickness Tpp, which can be substantially equal to the shaft thickness Ts and/or the shaft protrusion thickness Tsp.
Figure 11 provides an example of this enhanced grip, where the paddle protrusion 60 is disposed on the upper edge 42 of the paddle section 40.
Figure 11 shows a hand 70 of a user holding and/or gripping the paddle protrusion 60 near the gripping surface 22. As shown, the index finger 72 can be placed on one side and/or face of the paddle section 40. The thumb 79 is placed on the other side and/or face of the paddle section 40. Both the index finger 72 and the thumb 79 can apply a "pincer-type force, thereby squeezing both sides/faces of the paddle section 40 and securing the grip of the hand 70. As can be seen, the paddle protrusion 60 adapts the edge 42,44 on which it is located to the natural contour of the hand when it grips the shaft. Considering the example of a shaft 20 which is a goalie stick, this positioning of the index finger 72 and the thumb 79 is often used when the goalie wishes to manipulate the paddle section 40 so as to deflect, intercept, and/or stop a puck.
The paddle protrusion 60 is positioned, shaped, and sized to increase an edge thickness Te of at least one of the upper and lower edges 42,44. As with the shaft protrusion, the expression "increase an edge thickness Te" can mean that the edge thickness Te has a certain value at the edges 42,44, and that this value is increased on the edge and/or edges 42,44 on which the paddle protrusion 60 is located.
Such an increase in edge thickness Te can substantially adapt the edge 42,44 to the natural contour of the hand when it grips, or closes about, the shaft 20, thereby enhancing a grip of the hand. Optionally, the paddle protrusion 60 can define a paddle protrusion thickness Tpp, which can be substantially equal to the shaft thickness Ts and/or the shaft protrusion thickness Tsp.
Figure 11 provides an example of this enhanced grip, where the paddle protrusion 60 is disposed on the upper edge 42 of the paddle section 40.
Figure 11 shows a hand 70 of a user holding and/or gripping the paddle protrusion 60 near the gripping surface 22. As shown, the index finger 72 can be placed on one side and/or face of the paddle section 40. The thumb 79 is placed on the other side and/or face of the paddle section 40. Both the index finger 72 and the thumb 79 can apply a "pincer-type force, thereby squeezing both sides/faces of the paddle section 40 and securing the grip of the hand 70. As can be seen, the paddle protrusion 60 adapts the edge 42,44 on which it is located to the natural contour of the hand when it grips the shaft. Considering the example of a shaft 20 which is a goalie stick, this positioning of the index finger 72 and the thumb 79 is often used when the goalie wishes to manipulate the paddle section 40 so as to deflect, intercept, and/or stop a puck.
19 Indeed, this grip is also advantageous when the goalie wishes to counter the rotational force generated by a sharp impact of a puck with the blade of the goalie stick, for example. The increased edge thickness Te can advantageously conform to, or "fill", the natural contour formed by the index finger 72 and the thumb 79 when in this position, thus enhancing the grip of the user of the shaft 20, and ultimately, the user's control of the shaft 20.
In known shafts, when the index finger and the thumb form this position, the user's grip of the shaft can weaken because of a gap and/or looseness formed between these digits and the paddle section, which allows for the shaft so held to wiggle or loosen, especially upon a sharp impact by an object at a far enough moment arm. To counter such weakness, it would help if this gap could be "filled", or if the shaft conformed to this gap. It is thus appreciated that a shaft 20 with a greater surface area in contact with the index finger 72 and thumb 79 on an edge 42,44 of the paddle section 40, as described herein, can thus conform to the gap, and can thus improve the grip and rotational control of the shaft 20. This can allow the user to better resist forces (i.e. torsional, impactful, discrete, etc.) that may be applied against the shaft 20.
In another possible configuration, an example of which is provided in Figure 12, the paddle protrusion 60 projects from the lower edge 44 of the paddle section 40.
It is known that when the index finger wraps around the lower edge of a conventional shaft, the tapered nature of the shaft does not provide a sufficient point of contact between the fingertips of the index finger and the paddle section. This can lead to slipping and poor grip of the paddle section. It is thus desirable to enhance the contact between the index finger 72 and/or its fingertip, and the paddle section 40.
The paddle protrusion 60 can provide such an enhancement, by increasing the thickness of the lower edge 44, thereby providing a suitable contact surface against which the index finger 72 and/or fingertip can apply force so as to better "squeeze"
and/or control the paddle section 40.
In some optional configurations, examples of which are provided in Figures 13 to 17, the lower edge 44 of the paddle section 40 has a notch 46, which can receive a finger of the hand therein. Typically, this finger is the index finger. The notch 46 can be any indentation, cleft, cut, gash, groove, indent, etc. in an edge 42,44, such as the lower edge 44, of the paddle section 40 which can receive at least one finger therein.
As such, the notch 46, although shown in Figures 13 to 17 as a substantially "L"-shaped cut-away, can take any shape, contour, profile, form, etc. including, but not limited to, a semi-circle, a hole, a rectangle, a "U" shape, etc. Optionally, the notch 46 has a notch thickness Tr, which can be substantially equal to the shaft thickness Ts, which can be about 3/4". This can advantageously help the finger and/or fingertip within the notch 46 to have a thick or "meaty" edge, which can provide a better contact with the finger and/or fingertips, and ultimately, a better grip.
One example of a use of the notch 46 is provided when the index finger wraps around the paddle section 40. The index finger can be placed into the notch 46, and can apply force thereto so as to better grip the paddle section 40 and/or shaft 20.
When such a force is applied by the index finger, the user can better resist rotational and/or impact forces acting against the paddle section 40 and/or the shaft 20.
Without
In known shafts, when the index finger and the thumb form this position, the user's grip of the shaft can weaken because of a gap and/or looseness formed between these digits and the paddle section, which allows for the shaft so held to wiggle or loosen, especially upon a sharp impact by an object at a far enough moment arm. To counter such weakness, it would help if this gap could be "filled", or if the shaft conformed to this gap. It is thus appreciated that a shaft 20 with a greater surface area in contact with the index finger 72 and thumb 79 on an edge 42,44 of the paddle section 40, as described herein, can thus conform to the gap, and can thus improve the grip and rotational control of the shaft 20. This can allow the user to better resist forces (i.e. torsional, impactful, discrete, etc.) that may be applied against the shaft 20.
In another possible configuration, an example of which is provided in Figure 12, the paddle protrusion 60 projects from the lower edge 44 of the paddle section 40.
It is known that when the index finger wraps around the lower edge of a conventional shaft, the tapered nature of the shaft does not provide a sufficient point of contact between the fingertips of the index finger and the paddle section. This can lead to slipping and poor grip of the paddle section. It is thus desirable to enhance the contact between the index finger 72 and/or its fingertip, and the paddle section 40.
The paddle protrusion 60 can provide such an enhancement, by increasing the thickness of the lower edge 44, thereby providing a suitable contact surface against which the index finger 72 and/or fingertip can apply force so as to better "squeeze"
and/or control the paddle section 40.
In some optional configurations, examples of which are provided in Figures 13 to 17, the lower edge 44 of the paddle section 40 has a notch 46, which can receive a finger of the hand therein. Typically, this finger is the index finger. The notch 46 can be any indentation, cleft, cut, gash, groove, indent, etc. in an edge 42,44, such as the lower edge 44, of the paddle section 40 which can receive at least one finger therein.
As such, the notch 46, although shown in Figures 13 to 17 as a substantially "L"-shaped cut-away, can take any shape, contour, profile, form, etc. including, but not limited to, a semi-circle, a hole, a rectangle, a "U" shape, etc. Optionally, the notch 46 has a notch thickness Tr, which can be substantially equal to the shaft thickness Ts, which can be about 3/4". This can advantageously help the finger and/or fingertip within the notch 46 to have a thick or "meaty" edge, which can provide a better contact with the finger and/or fingertips, and ultimately, a better grip.
One example of a use of the notch 46 is provided when the index finger wraps around the paddle section 40. The index finger can be placed into the notch 46, and can apply force thereto so as to better grip the paddle section 40 and/or shaft 20.
When such a force is applied by the index finger, the user can better resist rotational and/or impact forces acting against the paddle section 40 and/or the shaft 20.
Without
20 the notch 46, the index finger could be trying to grip a "sloped" and/or "angled"
surface, which can increase the likelihood of the index finger slipping while the shaft 20 is being gripped. In one possible configuration, the notch 46 is configured about 90 degrees to an axial line of the index finger, thereby defining a "L"-shaped cut-away.
The notch 46 may further advantageously help those users having shorter fingers, or with fingers that cannot wrap around the lower edge 44 of the paddle section 40. The notch 46 can thus improve grip and torsional control for users of various hand sizes.
The present invention is an improvement over the prior art in that, by virtue of its design and components, the shaft 20 may reduce the amount of "dead space"
between the hand/fingers and the shaft 20, thereby increasing the amount of surface
surface, which can increase the likelihood of the index finger slipping while the shaft 20 is being gripped. In one possible configuration, the notch 46 is configured about 90 degrees to an axial line of the index finger, thereby defining a "L"-shaped cut-away.

The present invention is an improvement over the prior art in that, by virtue of its design and components, the shaft 20 may reduce the amount of "dead space"
between the hand/fingers and the shaft 20, thereby increasing the amount of surface
21 contact between the hand and the shaft 20 so as to enhance overall grip and control.
At levels of extreme competiveness, such as in professional and/or semi-professional sports, these enhancements, even if minor, are extremely advantageous and can distinguish a merely exceptional player from a top-of-class one.
In addition, a greater surface area of the shaft section 30 in contact with the hand can result in better control of the shaft 20 and resistance to the force applied thereby, which often improves performance for handling, control, manipulation, etc. in hockey, for example.
Furthermore, the shaft 20 may have an ergonomic design that is comfortable and that fits the natural contours of the hand, which facilitates its use.
In addition, the shaft protrusion 50 and/or the paddle protrusion 60 can be made of any of the following non-limiting examples of materials: rubber, plastic, foam, wood, leather, composite material, fibreglass, etc. The use of such materials can improve the comfort and/or grip of the shaft 20 while still allowing for an efficient manipulation. The various shapes and configurations of the shaft and/or paddle protrusions 50,60 can help to reduce and/or remove the natural gap created between the hand and/or fingers and the shaft 20, which enhances the contact surface between hand and shaft 20, and therefore the grip of the shaft 20 and its control.
Thus, it can be appreciated that the present invention may help a user, such as a goalie, for example, improve their ability to use the shaft 20 and the various functions accomplished therewith, such as handling, object control, deflection, interception, force application, etc. This is contrast to some conventional shafts, which prevent the user from obtaining a sufficient grip over the shaft. This contrast is made all the more apparent when viewing Figure 18, which provides an example of the shaft 20 described herein in comparison to a known goalie stick.
