Abstract

An adjustable and releasably lockable shaft for sporting goods, such as lacrosse sticks, and a method for adjusting and releasably locking the length of sporting goods shafts, is disclosed. The device may include a first shaft and a second shaft, which may be connected through a connector component. The connector component may provide structural support for one or both shafts, resisting flexion and deformation during use. One or both shafts may be unlocked and removed from the connector component, allowing for easier travel and storage. Shafts may also be connected when desirable, such as for defensive lacrosse play, or disconnected when shorter devices are desired, such as for offensive lacrosse play. Other components and structures may also be attached using similar methods and structures.

Description

    BACKGROUND
  • This application claims the priority of U.S. Provisional Patent Application No. 62/382,075 filed on Aug. 31, 2016, the disclosure of which is incorporated herein in its entirety.
  • The present disclosure relates generally to sporting goods which include shafts. More particularly, the present disclosure relates to an adjustable and releasably locking shaft for items such as lacrosse sticks. The present disclosure also relates to other items where adjustability of length may be desirable, such as paddles.
  • A variety of sporting goods products which include shafts, such as lacrosse sticks and kayak paddles, are well known in the art. These sporting goods products often prove to be difficult to travel with and burdensome to store due to their length. Attachable components or telescoping shafts have been explored, though these attempts have often proven overly complex, structurally weak, or otherwise unreliable or inconvenient to use. The risk of changing the length of the shaft of a lacrosse stick, also known as a crosse, during game play has also been suggested as a source of concern for rulemaking bodies, such as the NCAA Men's Lacrosse Rules Committee. Additionally, sports such as lacrosse have different length shafts for offensive and defensive positions. While having to travel with and store a very long stick for playing a defensive position, a player may also have to travel with and store a second, shorter stick for offensive play. A newcomer to the sport may have to purchase two separate sticks, one for each position, while discovering where that player's aptitudes are best utilized.
  • SUMMARY
  • The disclosure relates to an adjustable and releasably lockable shaft for sporting goods products. More specifically, the disclosure relates to an adjustable and releasably lockable shaft for a lacrosse stick, also referred to as a crosse.
  • The present invention is a sporting goods device, such as a lacrosse stick. Lacrosse sticks typically vary in length depending on the position played by the athlete. Including the head of a lacrosse stick, an offensive lacrosse stick will typically be 40″ to 42″ in length, while a defensive lacrosse stick will typically be 52″ to 72″ in length. The present invention provides a single device which can be adjusted for either defensive or offensive play, while also providing for easier storage and travel. The present invention may also be releasably lockable at the desired length.
  • The device may include a first shaft, a second shaft, and a connector. The first shaft, second shaft, and connector may connect along an axis which substantially passes longitudinally through all three components. In one embodiment, the first shaft and second shaft may each be 30″ long, though other lengths may also be used. The connector may be a separate or removable component from the second shaft, or may be connected to it or unitary with it. The first shaft and the connector may each include one or more locking features, such that when the first shaft locks onto the connector, the locking features resist translation of the first shaft along the longitudinal axis, thus preventing the first shaft from separating from the device when not desired. The bottom end of the first shaft may be proximal to or adjacent to the top end of the second shaft when both shafts are connected to the connector and locked into position. The top end of the first shaft may receive a lacrosse stick head, while the bottom end of the second shaft may optionally receive a lacrosse stick butt. When a shorter device is desired, the locking features may be actuated to release the locking function, allowing the connector to be disconnected from the first shaft.
  • Lacrosse stick shafts can be made from a variety of materials, including wood, plastic, fiberglass, titanium, aluminum, resin, and other metals and composites that are known in the art. Some flexibility is often desirable to lacrosse stick shafts, though the flexibility can be a weakness at connection points. The connector may be configured so that it provides structural support to the first shaft or to both shafts, such as to resist flexion of one or both shafts relative to the axis passing longitudinally through the connector. The connector may be made of metal, other suitably rigid materials, or any material that may achieve desirable performance while providing structural support to the device.
  • As many lacrosse stick shafts are at least partially hollow, the connector may be configured so as to be connected to one or both shafts by being inserted at least partially inside of one or both shafts. In such a way, the connector may be entirely, largely, or at least partially not visible when the device is fully assembled. By inserting the connector into one or both shafts, the impact of the connector on the cross-sectional perimeter of the device can be minimized, which can be a concern according to NCAA regulations. The connector may, similarly, be lockable with one or both shafts.
  • A shaft of the device may include an opening which may engage with a button or other protrusion which may extend from a surface of the connector. The protrusion may extend at least partially into the opening in the shaft when in a locked configuration. The protrusion may be pressed in, towards the inside of the connector, or otherwise actuated to cause the protrusion and the opening in the shaft to unlock, releasing the shaft from the connector. The button or other protrusion may be attached to the connector by means of a component or feature such as a spring, which may include a compression spring, torsion spring, leaf spring, or other means for flexion or resisting motion known in the art. The button may be pressed inward from the outside of the shaft and into an open area within the connector in order to unlock the shaft and adjust the length of the device.
  • The protrusion may also be a feature or structure on the connector without necessarily being a separate component. The connector may also have a flexible structure extending from it which includes the protrusion, or may be slotted, recessed, or otherwise configured to create an at least partially flexible portion to allow for actuation of the protrusion away from the complementary locking opening or structure in the shaft.
  • The connector may also seat at least partially around one or both shafts, with a shaft at least partially recessed within the connector. In such a design, the locking features may be switched between the connector and one or both shafts. This may offer a less expensive alternative design, though a connector which seats within one or both shafts may be preferable for gameplay.
  • In one embodiment, the connector may provide structural support to at least 10% of the longitudinal length of one or more shaft components. It should be understood that other length of support may also be implemented without deviating from the spirit or intent of the invention and disclosure. Lengths may include, but are not limited to, 1″ to 12″ of support for one or both shaft components, such as a connector which extends 6″ into a shaft.
  • The lockable feature between a shaft and the connector may also be released by means of sliding a feature rather than by depressing it inwards into the device. A button or other similar structure may be actuated so as to slide an unlocking surface towards a complimentary unlocking feature in the other component. As one example, a button on a shaft may be slid towards the connector, causing a component in the shaft to contact an angled and at least partially flexible feature in the connector, causing it to deflect and thereby unlock the shaft from the connector. The features and orientation may also be switched and reversed.
  • The first shaft may also be threaded onto the second shaft. Standard threading may not guarantee proper orientation and may not provide adequate structural support or locking at the interface. However, the first shaft may include a threaded feature, such as a ring. This ring may be connected to the first shaft so as to be able to freely rotate about the axis passing longitudinally through the first shaft. The ring may, however, be captured by a feature on the first shaft so as to prevent or limit its translation along the axis. The first shaft may also include a connector which may include a keying feature extending from the bottom of the first shaft and within the ring. This connector may also be a separate component which may be inserted into one or both shafts. The second shaft may include a threaded feature which may attach to the threads of the ring. The second shaft may also include a complimentary keying feature configured to interact with the connector extending from the first shaft. The keying feature may prevent rotation of the second shaft relative to the first shaft, while also providing structural support between the two. When the ring is rotated, the second shaft and first shaft thread together, while translating towards each other without relative rotation due to the keying structure of the connector interface with the second shaft. It should be understood that the keying feature may be on either shaft, including extending inside of the ring component from the opposed shaft.
  • A lacrosse stick head may be connected to a shaft using known means, such as a press-fit or using a set screw, or through similar means to those discussed above for connecting a shaft with a connector or with another shaft. A lacrosse stick butt may also be connected to a shaft through similar means. The connection means for any component may also be a flexible or partially flexible structure with a locking feature, such as a button. This may be pressed into the shaft, flexing towards the inside of the shaft, until it releasably locks into place at an opening or other locking structure within the shaft.
  • A common cross-sectional shape for lacrosse sticks is substantially hexagonal. One or more of the two shafts and the connector may be hexagonal in cross-section. The components may also be configured and sized so as to line up when one is inserted into another, such as where the outside shape of the connector substantially conforms to the internal shape of a shaft. However, one of the components, such as the connector, may also be sized and shaped differently, such as a rectangle or with a substantially circular cross-section. The component may also be sized or shaped so as to be rotatable within its complimentary components, such as a connector which may rotate within a shaft. The connector may be configured to rotate about the longitudinal axis passing through the shaft until the connector's locking feature interfaces with the shaft's complimentary locking feature.
  • The above discussed device may also be used with other types of sporting goods and products where adjustability of length and releasable locking may be desirable. The device may have a paddle blade attached to one or both shafts, as mentioned for lacrosse stick heads and butts, or may include other desirable portions of athletic instruments.
  • It is to be understood that the above mentioned features and the features yet to be explained hereinafter can be used not only in the respectively mentioned combinations but also in other combinations or alone without departing from the context of the present invention and disclosure.

  • DETAILED DESCRIPTION
  • Exemplary embodiments of the disclosure are illustrated in the Figures and are explained in the following description in more detail, wherein identical reference numbers refer to identical, or similar, or functionally identical components.
  • Various aspects of the illustrative embodiments will be described using terms commonly employed by those skilled in the art to convey the substance of their work to others skilled in the art. However, it will be apparent to those skilled in the art that the present invention may be practiced with only some of the described aspects, without certain details, or where well-known features are omitted or simplified in order not to obscure the illustrative embodiments, without deviating from the spirit and intent of the disclosure.
  • Various operations will be described as multiple discrete operations, in turn, in a manner that is most helpful in understanding the present invention. However, the order of description should not be construed as to imply that these operations are necessarily order dependent or that they need to be performed in the order of presentation.
  • The phrase “in one embodiment” is used repeatedly. The phrase generally does not refer to the same embodiment, however, it may. The terms “comprising”, “having” and “including” are synonymous, unless the context dictates otherwise.
  • FIG. 1 shows a front isometric view of an embodiment of the adjustable locking shaft device 100. In the embodiment shown, the device 100 is a crosse, and includes a head 110, a first shaft 120, a second shaft 130, and a butt 150. The device 100 may also include one or more locking buttons 146. Each button 146 may be actuated, such as by depressing it inwards into the device 100, so as to unlock and release a component of the device 100. As shown in this embodiment, the head 110 and the butt 150 are each unlockable by means of actuating a button 146. It should be understood, however, that either or both of these components may be attached through other means, such as through the use of a set screw, a press fit, or through other means known in the art.
  • In the embodiment of the device 100 shown in FIG. 1, the first shaft 120 and the second shaft 130 connect by means of a connector subassembly 140, which passes within both the first shaft 120 and the second shaft 130. The connector subassembly 140 provides not only connection and locking features, such as the locking buttons 146, but also provides structure support at the connection and strengthens both the first shaft 120 and the second shaft 130, reducing flexion and stress on the connection. The first shaft 120 and the second shaft 130 may also both be identical or substantially identical components, including having substantially the same length and connection features. While the device 100 may be used when a longer overall shaft length is desired, such as for defensive play in lacrosse, the connector subassembly 140 and the second shaft 130 may be unlocked and disconnected from the first shaft 120 when a shorter overall shaft length is desired, such as for offensive play or for travel or storage. A butt 150 may be attached to the bottom of the first shaft 120. A second head 110 may also be attached to the top of the second shaft 130, providing a second offensive lacrosse stick.
  • FIG. 2 shows a front view of an embodiment of the device 10, while FIG. 3 shows an exploded view of the device 100. As can be seen in FIG. 3, the connector subassembly 140 may be completely removed from the device 100, enabling a user to use either the first shaft 120, the second shaft 130, or both as components of shorter lacrosse sticks.
  • FIG. 4 shows a side sectional view of the connection interface of an embodiment of the device 100. The connector subassembly 140 may seat fully within a substantially open volume 125, 135 within the first shaft 120 or the second shaft 130, or both. Though the connector subassembly 140 may be fixed to one of the first shaft 120 or the second shaft 130, such as through welding, and only sit within and lock to the other of the first shaft 120 or the second shaft 130, respectively, by having the connector subassembly 140 seat within an open volume 125, 135 within both the first shaft 120 and the second shaft 130, it may strengthen both shafts 120, 130 when connected while allowing either shaft 120, 130 to be used for a shorter lacrosse stick when disconnected.
  • As further shown in FIG. 4, the connector subassembly may include one or more springs 147. The spring 147 may be configured to support one or more buttons 146 in a locking orientation in the device 100. Though a leaf spring 147 is shown, it should be understood that other methods of creating bias, such as compression springs or deflection of material within its elastic range of deformation, among other methods known in the art, may also be used without deviating from the spirit or intent of the disclosure. It should also be understood that, though a single button 146 is shown per locking connection, multiple buttons may also be used. If one button 146 is used, with a second button 146 substantially diametrically opposed to it, this may provide additional locking support while reducing the likelihood of unintentional unlocking of the connection. An opening 148 is shown, which may be used for welding of the spring 147 to an interior face 149 of the connector body 145. It should be understood that the spring 147 may be connected to the connector body 145 through other means, such as through the use of a fastener. The fastener may also pass through the opening 148.
  • FIG. 5 shows a front isometric view of a connector subassembly 140 of an embodiment of the device 100, while FIG. 6 shows a sectional side view of the connector subassembly 140. In the embodiment shown, the buttons 146 pass through the connector body 145 so as to be sufficiently proud from an outside surface 144 of the connector body 145 so as to be able to interlock with locking holes 121 in the first shaft 120 and the second shaft 130.
  • FIG. 7 shows an isometric view an embodiment of a connector body 145, including pass-through openings 143 to permit one or more buttons 146 to connect to spring components 147 to be placed within the connector body 145. In the embodiment shown, the connector body 145 is substantially hexagonal in cross-section, so as to conform to the interior cross-section of hexagonal lacrosse shafts 120, 130. It should be understood, however, that the connector body may be configured in a wide range of shapes, including substantially circular or rectangular. Rotation of the connector body 145 within either the first shaft 120 or the second shaft 130 may be prevented by one or more anti-rotation features, such as a flat surface, or by the one or more buttons 146 themselves.
  • FIG. 8 shows a shaft 120, 130, including locking holes 121 configured to receive buttons 146. Though the embodiment shown includes locking holes 121 for connections at both ends of the shaft 120, 130, it should be understood that the shaft 120, 130 may be configured to only receive a connector subassembly 140 at one end, while a standard butt 150 or head 110 connection may also optionally be used at the other.
  • FIG. 9 shows an embodiment of a butt 150 which may be used with an embodiment of the device 100 of the present disclosure. The butt 150 includes a support area 151, configured to support a shaft 120, 130 from within an internal volume 125. The butt 150 also includes a button 152 located substantially along an at least partially flexible structure 153 extending from the butt 150. The flexible structure 153 may also be substantially rigid, but able to flex without plastic deformation or failure when force is applied directly or indirectly to the flexible structure 153 so as to allow the button 152 to unlock the butt 150 from a shaft 120, 130. It should be understood that alternate embodiments of the butt 150 may also be used, such using a button 152 with a spring 147, as is used in the connector subassembly 140. The same connection and locking means as used in the butt 150 may also be used for connecting a head 110 to a shaft 120, 130. Further, in an alternate embodiment of a connector body 145, one or more support areas 151 may be used along with one or more flexible structures 153 and one or more buttons 152 to connect a first shaft 120 to a second shaft 130, thus reducing the number of subcomponents needed for a connector subassembly 140. Any or all of the above combinations of components and features may be combined together to achieve desired results without deviating from the spirit or intent of the disclosure.
  • FIG. 10 shows an isometric view of an alternate connector body 245 which may be used with various embodiments of the device 100, while FIG. 11 shows a front view of the connector body of FIG. 10. The connector body 245 is shown substantially cylindrical, allowing for insertion of the connector body 245 into the first shaft 120 or the second shaft 130, locking into position by twisting the connector body 245 until a locking button 246 enters a locking hole 121. It should be understood that other cross-sectional shapes of the connector body 245 may also be used without deviating from the spirit or intent of the present disclosure. In the embodiment shown in FIG. 10, the connector body 245 includes slots 242 which permit a structure 253 to flex so as to allow insertion of the connector body 245 into a shaft 120, 130, or to allow for rotation of the connector body 245 within the shaft 120, 130. The structure 253, along with the locking button 246, can flex to allow for connection of the connector body 245 to a shaft 120, 130, as well as allowing for flexion so as to unlock and disconnect the connector body 245 from a shaft 120, 130. If a substantially cylindrical connector body 245 is used, significant hoop strength may be maintained despite the slots 242, allowing for the connector body 245 to provide strength and support to the device 100. The use of one or more flexible structures 253 may reduce or eliminate the need for springs 147 and other additional components.
  • FIG. 12 shows an isometric view of another embodiment of the device 300, including a depth stop feature 360. As shown in FIG. 13, a depth stop feature 360 may be included, such as on the connector body 345. The depth stop feature 360 may be used to prevent the connector body 345 from passing too deep into the open volume 125 of a shaft 120, 130. Though a depth stop feature 360 may be used with a variety of embodiments of the device 300, it may be particularly desirable if the connector body 345 does not include any keying features to guide orientation of the connector body 345 and locking button 346 within the shaft 120, 130. Where a locking button 346 may be misaligned with a locking hole 121 in a shaft 120, 130, the depth stop feature 360 can aid in translational axial alignment of the connector body 345 with the shaft 120, 130, thus only requiring rotation of the connector body 345 to lock a shaft 120, 130 in place.
  • FIG. 14 shows an isometric view of another embodiment of the device 400 of the present disclosure. The device 400 is configured so as to unlock a shaft 420, 430 from the connector body 445 by sliding a release button 446. By connecting the release button 446 to the connector body 445 in a slidable manner, the profile of the release button 446 may be configured so as to minimize any amount that it may extend proud from the shaft 420, 430 when locked into position. In a preferred embodiment, the release button 446 may be configured so as to slide towards the midline of the longitudinal length of the connector body 445 when unlocking the shaft 420, 430, thus minimizing unintentional separation of a shaft 420, 430 from the connector body 445 by requiring force upon the release button 446 in an opposite direction from force pulling the shaft 420, 430 away from the connector body 445. It should be understood, however, that different configurations and orientation of the actuation of the release button 446 may be used without deviation from the spirit or intent of the disclosure.
  • FIG. 15 shows a side sectional view of a connection interface of the embodiment of the device 400 shown in FIG. 14. In this embodiment, one or more release buttons 446 slide within a release channel 471 within a shaft 420, 430. The release button may be connected to a slider component 472 which itself may include an unlocking feature 473. When the release button 446 is slid into an unlocking orientation, the unlocking feature 473 may interact with a complimentary feature 474 on the connector body 445, causing a locking tooth 475 or other similar locking feature on the connector body 445 to deflect substantially out of a locking key 476 in the shaft 420, 430, allowing the connector body 445 and the shaft 420, 430 to be separated.
  • FIG. 16 shows an isometric view of an embodiment of a connector body 445, such as that in the embodiment of FIG. 14. Though the connector body 445 is shown substantially cylindrical, it should be understood that a wide range of cross-sectional shapes may be used, including rectangular and hexagonal.

Each flexible structure 453 may include a locking tooth 452 which may be configured to fit into and lock with a locking key 476 in a shaft 420, 430. It should be understood that a similar design may be used to connect a head 410 to a shaft 420, 430. Though FIG. 18 shows two flexible structures 453, it should be understood that fewer or more than two could be used without deviating from the spirit or intent of the disclosure.
  • FIG. 19 shows an isometric view of another alternate embodiment of the device 500 of the present disclosure. In this embodiment, the head 510, the first shaft 520, or the second shaft 530 may each or all be connected through the use of a keying feature 581 and substantially freely rotating threaded ring 580. The keying feature 581 provides alignment for one component, such as a first shaft 520, when locking with a second component, such as a second shaft 530. The keying feature can also provide strengthening support to the component into which it is inserted. The threaded ring 580 rotates substantially freely around the longitudinal axis of the component to which it is rotatably connected, while having threading features 583 to connect to and hold a second component in position. FIG. 20 shows an exploded view of the embodiment of the device 500 of FIG. 19, showing that if the threaded ring 580 extends axially below the keying feature 581, then a butt 150 may not be needed. In such a configuration, the threaded ring 580 may be coated with a soft or rubber-like material, or may itself be made of such a material, such as a plastic.
  • FIG. 21 shows a side sectional view of a connection interface of the embodiment of the device 500 of FIG. 19. The threaded ring 580 is able to rotate substantially freely upon retention features 584 on the first shaft 520 while threading onto threading features 586 on the second shaft 530. The keying feature 581 on the first shaft 520 slots into a receiving feature 585 in the second shaft 530, allowing the second shaft 530 to translate axially without substantial rotation while the threaded ring 580 of the first shaft 520 threads onto the threading features 586 of the second shaft 530. It should be understood that similar connection and locking features may be used for connections among any of the components of the device 500.
  • FIG. 22 shows an isometric view of a shaft body 520, 530 without a threaded ring 580, for clarity. Though the shaft body 520, 530 is shown with a substantially hexagonal cross-section, other cross-sectional profiles may be used for the shaft bodies 520, 530 of this and other embodiments of this disclosure. Though substantially hollow shaft bodies 520, 530 may be preferable for weight reduction, substantially solid shaft bodies 520, 530, or partially hollow shaft bodies 520, 530 may also be used without deviating from the spirit or intent of the disclosure.
