Description
Title of the Invention A kit for extending the shaft of a hockey stick Cross-Reference to Related Applications [0001] The present patent application claims the benefits of priority of commonly assigned US Patent Application No. 62/436,839, entitled "Kit for extending the shaft of a hockey stick" and filed at the USPTO on December 20, 2016.
Field of the Invention
Field of the Invention
[0002] The present invention generally relates to sport gear, and in particular to a kit for adjusting the length of a hockey stick. More particularly, the present invention relates to kit for extending the shaft of a hockey stick for kids when the kids are growing up.
Background of the Invention
Background of the Invention
[0003] An adequate length for a hockey stick consists in having the end of the shaft of the hockey stick facing around the nose of the user when the stick is vertical on the floor.
When a kid playing hockey is growing up, the length of its hockey stick needs to be regularly adapted. Conventionally, the stick is replaced by a new longer stick, which can be costly. Another method consists in adjusting the length of a hockey stick by replacing the shaft with a new shaft that has a longer length. This method is not always convenient in that the longer of the shaft is not adjustable in view of the kid's size.

Another method consists in adjusting the length of a hockey stick by replacing the shaft with a new shaft that has a longer length. This method is not always convenient in that the longer of the shaft is not adjustable in view of the kid's size.
[0004] Furthermore, other methods for adjusting the length of a hockey stick require some adjustments and modifications to be done on the shaft of the hockey stick to render it adapted to receive extension components. Thus, such a method makes the shaft of a hockey stick confronted to many risks of deterioration and damage during machining operations.
[0005] Some devices are known for extending the length of a golf stick. For instance, the device disclosed in the US patent n . 8,814,718 BI, uses complex extension components to prevent the undesirable sudden detachment of the extension system from the shaft of a golf stick. These components are considered complex since they also comprise extending structural elements in order to prevent the inter-module rotation. Generally, the machining of such components is demanding and costly.
[0006] Finally, the devices for extending the length of a golf stick disclosed in the US
patent application n'.2011/0159982 Al, do not allow having an optimal length of the stick since the extension components have all the same length.
patent application n'.2011/0159982 Al, do not allow having an optimal length of the stick since the extension components have all the same length.
[0007] There is a continuous need for extension systems for hockey sticks.

[0040] In reference to Figure 1, a hockey stick 100 is illustrated The hockey stick 100 generally comprises a head 10 connected to a lower portion 32 of a shaft 30.
The shaft 30 comprises a hollow tubular structure presenting a hollow end 31. As aforesaid, an adequate length for a hockey stick consists in having the end of the shaft facing around the nose of the user when the stick is vertical on the floor.
[0041] The hockey stick as shown in Figure 1 also comprises a kit 20 for extending the shaft 30 of the hockey stick 100. The kit 20 is configured to be attached to the hollow end 31 of the shaft.
[0042] Figures 2 to 5 illustrate a first preferred embodiment of a kit 21 for extending the shaft of the hockey stick.
[0043] The kit 21 comprises a shaft fixing module 13 adapted to be inserted in the hollow end 31 of the shaft and a plurality of extension modules 50 configured to nest one in the other. The kit 21 may further comprise an attachment module 37 (Fig. 3) long enough to pass through all extension modules 50. The kit may also comprise a cap 39 adapted to nest in the top of the last extension module 50 [0044] The shaft fixing module 13 comprises an external surface 15 configured to be inserted into the hollow end 31 of the shaft of the hockey stick, an orifice, in the current embodiment an inner central threaded hole 17 characterized by an axis 44, and an end portion 18 preferably comprising a collar 19. The collar 19 is configured to abut the shaft fixing module 13 on the hollow end 31 of the shaft 30 and optionally to fit with the outer surface of the shaft. The end portion 18, in the current embodiment further comprising a female section 22, is adapted to host a bottom section 27, in the current embodiment a male section, of an extension module 50.
[0045] In a preferred embodiment, each extension module 50 of the kit comprises a main body 25 haying a contour matching the end portion 18, the collar 19 and the shaft 30.
Each extension module may further comprise a bottom male section 27 and a top female section 29. The bottom male section 27 extends from the main body 25 and is configured to fit either to the female section 22 of the shaft fixing module or to the top female section 29 of another extension module to increase the length of the shaft of the hockey stick. The top female section 29 is defined within the main body 25 of an extension module and configured to fit either to the bottom male section 27 of a subsequent extension module or to a bottom male section 41 of the cap 39.
[0046] In a preferred embodiment, each extension module comprises a central orifice or hole 35 going through the module and characterized by a longitudinal axis 43 Each axis 43 of each central hole 35 is adapted to be aligned with the longitudinal axis 44 of the inner central threaded hole 17 of the shaft fixing module when the extension module 50 nest in the top of the shaft fixing module 13.
[0047] In a preferred embodiment, all the axis 43 of all the central holes 35 of all the extension modules 50 are adapted to be aligned when the extension modules 50 nest one in the other.
[0048] The extension modules 50 preferably have different length as shown in Figures 4, 7 or 12, allowing precisely adjusting the length of the extension kit in function of the person.
[0049] In reference to Figure 3, the attachment module 37 may be long enough to pass through all extension modules 50 and to be attached to the inner central threaded hole 17 of the shaft fixing module 13 to firmly link the extension module(s) to the shaft fixing module 13 to form an extended shaft of a hockey stick [0050] In a preferred embodiment, the kit 20 may have a cap 39 to cover the last extension module and nest in the top of the attachment mean 37.
[0051] Figures 6, 7 and 8 illustrate other embodiments of a kit 20 for extending the shaft of a hockey stick The bottom male section 27 of the extension module 50, the female section 22 of the shaft fixing module 13 and the top female section 29 of the extension module 50 may have a square or rectangular shape to firmly clamp the extension modules one to the other. Such a shape allows easily maintaining the extension modules in place before receiving the attachment module 37.
[0052] Now referring to Figures 8 to 11, where another embodiment of a shaft fixing module is shown, the shaft fixing module 13A comprises a blind hole 17A
adapted to receive a fastener 2, such as, but not limited to a nut, preferably made of a metallic material or any material resisting to wear. The insertion of the fastener 2 inside the shaft fixing module 13A also aims to provide better mechanical properties for the shaft fixing module once assembled to the extension modules.
[0053] In another preferred embodiment, the shaft fixing module 13A may comprise a hole presenting at least two different inner diameters adapted to receive the fastener 2.
The shaft fixing module may enlarge or extend transversally once the attachment mean is inserted in the shaft fixing module [0054] In another embodiment, the extension modules may compress or extend transversally to nest one in the other or to nest in the shaft fixing module.
[0055] It is to be understood that other shape for the bottom male section 27 and top female section 29 of the extension module 50, the female section 22 of the shaft fixing module 13 may be adapted once it allows the extension modules to correctly nest one in the other, to correctly nest in the shaft fixing module and to correctly receive the cap 39.
Similarly to the extension module 50 having a main body 25 with a contour matching the end portion 18, the collar 19 and the shaft 30, cap 39, when attached to such extension module 50, may have an external surface adapted to match the contour of such main body 25 (and therefore matching the outer surface of the shaft 30 of the hockey stick 100) Alternatively, cap 39 may have an external surface, when attached to extension module 50, radially further away from axis 35 than the contour of main body 25 of extension module 50, this may be accomplished by having a female bottom section 41 of cap 39 being large enough to be placed around the contour of main body 25 (it is understood by someone skilled in the art that other types of caps 39, adapted to form a knob at an extremity of the hockey stick 100, are possible pursuant to the invention) Such a cap is advantageous as many users of hockey sticks have a need for knobs at the extremity of their hockey sticks (and often end up using hockey tape to accomplish this) [0056] Any shape of holes may be adapted for both the extension modules and the shaft fixing module once all the axis of all the central holes of all the extension modules are adapted to be aligned when the extension modules nest one in the other and once each axis of each central hole is adapted to be aligned with the axis of the inner central threaded hole of the shaft fixing module when the extension module nest in the top of the shaft fixing module [0057] It is also disclosed a method for extending the shaft of a hockey stick. The method comprises inserting the external surface 15 or 15A into the hollow end 31 of the shaft of the hockey stick. The external surface can be glued inside the shaft of the hockey stick.
The method further comprises inserting the bottom male section 27 of a first extension module 50 into a female portion located on the top of the shaft fixing module 13 or 13A
in a way that the axis of the extension module 50 is aligned with the axis of the shaft fixing module 13 or 13A Furthermore, the method comprises inserting the fastener mean

Similarly to the extension module 50 having a main body 25 with a contour matching the end portion 18, the collar 19 and the shaft 30, cap 39, when attached to such extension module 50, may have an external surface adapted to match the contour of such main body 25 (and therefore matching the outer surface of the shaft 30 of the hockey stick 100) Alternatively, cap 39 may have an external surface, when attached to extension module 50, radially further away from axis 35 than the contour of main body 25 of extension module 50, this may be accomplished by having a female bottom section 41 of cap 39 being large enough to be placed around the contour of main body 25 (it is understood by someone skilled in the art that other types of caps 39, adapted to form a knob at an extremity of the hockey stick 100, are possible pursuant to the invention) Such a cap is advantageous as many users of hockey sticks have a need for knobs at the extremity of their hockey sticks (and often end up using hockey tape to accomplish this) [0056] Any shape of holes may be adapted for both the extension modules and the shaft fixing module once all the axis of all the central holes of all the extension modules are adapted to be aligned when the extension modules nest one in the other and once each axis of each central hole is adapted to be aligned with the axis of the inner central threaded hole of the shaft fixing module when the extension module nest in the top of the shaft fixing module [0057] It is also disclosed a method for extending the shaft of a hockey stick. The method comprises inserting the external surface 15 or 15A into the hollow end 31 of the shaft of the hockey stick. The external surface can be glued inside the shaft of the hockey stick.
The method further comprises inserting the bottom male section 27 of a first extension module 50 into a female portion located on the top of the shaft fixing module 13 or 13A
in a way that the axis of the extension module 50 is aligned with the axis of the shaft fixing module 13 or 13A Furthermore, the method comprises inserting the fastener mean
37 through the extension module 50 and to be attached to an inner central threaded hole 17 of the shaft fixing module 13 or 13A to firmly link the extension module(s) to the shaft fixing module 13 or 13A to form an extended shaft of the hockey stick [0058] In another embodiment, the method may further comprise inserting the bottom male section 27 of a second extension module 50 into the female portion of the first extension module 50 in a way that the extension modules nest one in the other.
[0059] Finally, the method comprises inserting a cap 39 to cover the last extension module 50 and nest in the top of the attachment mean 37.
[0060] Advantageously, the kit disclosed herein offers a faster, easier and less expensive system and method for adapting hockey stick's length than the ones currently existing.
[0061] Besides, the kit provides more flexibility to get an optimal and suitable length for a user since it comes with different modules having different lengths.
[0062] The kit further provides an easy and secure mounting to the shaft of a hockey stick thanks to the clipping modules. With such a system, the user does not have to prevent the sudden detachment of the system due an undesirable inter-rotation between the modules [0063] While illustrative and presently preferred embodiments of the invention have been described in detail hereinabove, it is to be understood that the inventive concepts may be otherwise variously embodied and employed and that the appended claims are intended to be construed to include such variations except insofar as limited by the prior art. For example, whereas in a previously described embodiment the external surface 15 of the shaft fixing module 13 slideably fits and is glued inside the hollow end 31 of the shaft 30 of the hockey stick 100, it is possible to have a shaft fixing module 13 with an external surface being pressure-fitted inside to the inner surface of the hollow end 31 of the hockey stick 100 such that glue is not necessary, any other combination where the external surface of the shaft fixing module 13 is securely connected (for the purpose of preventing the extension kit from detaching itself from the hockey stick 100 during use) to the inner surface of the hollow end 13 of the hockey stick 100 is possible pursuant to the invention In a further example, whereas in a previously described embodiment the end portion 18 of shaft fixing module 13 comprises a female section 22 adapted to host a male bottom section 27 of an extension module 50, it is possible pursuant to the invention for end portion 18 to comprise a male section adapted to host a female section of an extension module 50, any other combination, where the end portion 18 of shaft fixing module 13 and bottom section 27 of extension module 50 are configured to mate with one another, is possible pursuant to the invention Similarly, whereas in a previously described embodiment the top female section 29 of an extension module 50 is adapted to host a male bottom section 27 of an extension module 50 (and to also host a male bottom section 41 of a cap 39), it is possible pursuant to the invention to have a top male section of an extension module 50 adapted to host a female bottom section of an extension module 50 (and to also host a female bottom section 41 of a cap 39), any other combination, where the top section 29 of extension module 50 and the bottom section 27 of extension module 50 (and the bottom section 41 of a cap 39) are configured to mate with one another, is possible pursuant to the invention.
