Description

Technical Field

[0001] This disclosure generally pertains to the field of sports rackets. Background Technology

[0002] Racquet players, amateurs, and professionals carefully select their rackets because finding the best racket requires considering many parameters. These parameters include, for example, the type of materials used in different parts of the racket, the assembly of the racket's components, and the racket's shape or appearance. One of the most important parameters is the weight and balance of the racket's handle.

[0003] Therefore, many racket players attempt to customize their equipment to suit their personal preferences. For example, some players use lead-based straps to adjust the weight and balance of the racket handle. However, such application can be time-consuming, inaccurate, difficult to replicate, and / or may negatively impact other racket parameters, such as grip. Furthermore, lead-based straps can easily detach, requiring replacement in such cases.

[0004] Therefore, it makes sense to provide a racket with improved weight and balance and adjustability. Summary of the Invention

[0005] Therefore, the purpose of this disclosure is to provide a racket that allows players to easily and quickly adjust the weight and balance of the racket.

[0006] To achieve this objective, this disclosure provides a racket including a socket and a plug as defined in the independent claim. Further embodiments are provided in the dependent claims.

[0007] According to one aspect of this disclosure, a racket is provided. The racket includes a handle and a racket face. The handle includes a socket disposed at an end portion of the handle. The socket extends into the handle along the central longitudinal axis of the racket, and can also be understood as the socket extending into the handle along the central longitudinal axis of the handle. The socket includes a first magnetic material disposed therein. The racket further includes a plug configured to be disposed in the socket. The plug includes a second magnetic material configured to magnetically attract the first magnetic material.

[0008] The handle can extend longitudinally, and one longitudinal end of the handle can be attached to the racket face, while the other longitudinal end of the handle can include a socket. A first magnetic material can be disposed in, at, and / or within the socket. The surface of the racket face can be configured to attach one or more covering layers or surface materials, such as a rubber layer. The term "magnetic material" refers to, for example, a permanent magnet, or a material attracted by magnetic force, such as a magnetic metal. The plug can be alternatively understood as an insert or filler.

[0009] This disclosure is based on the concept of providing a racket including a socket configured to receive a plug, thereby altering the racket's weight and / or balance, and particularly the weight and / or balance of the racket's handle. Therefore, the plug can be alternatively understood as a weighted plug. Further, the socket can be configured to receive one of a plurality of plugs. Each of the plurality of plugs can be configured to be disposed within the socket. In other words, each plug can have a shape that allows the plug to be disposed within the socket. Each of the plurality of plugs can have a different weight than the other plugs in the plurality of plugs. Therefore, the racket's weight and / or balance can be easily adjusted by switching between plugs of different weights.

[0010] The configuration of the sockets and plugs, each with its own magnetic material, for magnetic attraction allows for quick and easy placement of the plugs into the sockets or connection of the plugs and sockets. The magnetic material further provides a secure placement of the plugs into the sockets. A more secure placement of the plugs into the sockets prevents them from rattling or vibrating within the sockets, thus providing an improved user experience. Furthermore, this quick and easy placement translates into quick and easy switching of the plugs. In other words, the racket according to this disclosure allows players to quickly and easily switch between plugs of different weights to experiment with different weights and / or balances.

[0011] The racket can be any type of sport racket, such as a table tennis racket, tennis racket, badminton racket, or padel (cage tennis) racket. In other words, the above-described concept of providing a racket including a socket (which is configured to receive a plug) is not limited to a racket for any particular sport.

[0012] The plug may include a flange. The flange may be disposed at an end portion of the plug. The flange may alternatively be understood as, for example, an edge, lip, or ledge disposed at the end portion of the plug. The plug may include two end portions, wherein a first end portion may be configured to be inserted into a socket, and a flange may be disposed at a second end portion. The flange may extend or project away from the central longitudinal axis of the plug. Further, the flange may extend or project radially from the central longitudinal axis of the plug. Additionally, the flange may extend from one or more sides of the plug extending between the end portions of the plug. The flange may form part of an end portion of the plug. When the plug is disposed in a socket, the flange may be disposed abutting at least a portion of the longitudinal end of a handle. The flange may prevent the entire plug from being inserted into or disposed within the socket, thereby providing easier removal of the plug from the socket. Further, the flange may act as a wedge or grip for the user or player to remove the plug from the socket. Thus, the flange provides additional ease of removal of the plug from the socket.

[0013] The plug may include a surface extending between a portion of the flange and a side of the plug, which may serve as a transition from one or more sides of the plug to the flange.

[0014] The socket can have a chamfered, tapered, or beveled shape. The first diameter of the socket, measured at the end of the handle, can be larger than the second diameter measured at the bottom of the socket. The shape of the socket allows the plug to wedge into it, providing a secure placement of the plug within the socket. Furthermore, the shape of the socket prevents plugs, excluding the flange, from being fully inserted or positioned within the socket, thus providing easier removal of the plug from the socket. A tapered shape is advantageous because it makes the socket easier to manufacture, as the handle can be drilled.

[0015] The plug can have a chamfered, tapered, or beveled shape. For example, the plug can have a shape based on a cone or frustocone. The first diameter of the plug, measured at a first end portion, can be larger than the second diameter of the plug, measured at a second end portion. The shape of the plug and the shape of the socket can be related such that when the plug is inserted into or positioned in the socket, the side of the plug can abut against the side of the socket. The shape of the socket and the shape of the plug can be complementary so as to substantially match. In other words, the space defined by the shape of the socket can be substantially equal to the shape of the plug or the shape of at least a portion of the plug. The shapes of the plug and the socket can allow the plug to fit tightly in the socket. Furthermore, when both the plug and the socket are chamfered, tapered, or beveled, the plug can be wedged in when inserted into the socket, thereby being securely positioned in the socket, which can prevent the plug from making a rattling sound and / or vibrating when positioned in the socket.

[0016] The length of the socket along its central longitudinal axis can be greater than the length of the plug along its central longitudinal axis. The length of the socket along its central longitudinal axis can also be greater than the length between the end portion of the plug and its flange. In other words, the length of the plug segment that can be inserted into the socket can be less than the length of the socket.

[0017] The difference in length can allow for a gap or space between the bottom of the socket and the end portion of the plug. Furthermore, the combination of a difference in length with a plug including a flange can allow for a gap or space between the bottom of the socket and the end portion of the plug. Additionally, the combination of a difference in length with a socket and / or plug including a chamfered, tapered, or beveled shape can allow for a gap or space between the bottom of the socket and the end portion of the plug.

[0018] The magnetic attraction between the first and second magnetic materials secures the plug to the socket, and the gap or space between the bottom of the socket and the end portion of the plug allows the plug to be pulled towards the bottom of the socket rather than adjacent to it. The plug being pulled towards the bottom of the socket can reduce the rattling and / or vibration noise when positioned within the socket.

[0019] A first magnetic material can be disposed at the bottom of the socket, which allows the magnetic attraction between the first and second magnetic materials to pull along the central longitudinal axis of the racket, thereby providing a secure placement of the plug into the socket. Furthermore, placing the first magnetic material at the bottom of the socket can facilitate easier racket manufacturing. The first magnetic material can be attached to the bottom of the socket by a fastening device (such as glue) and / or by wedging it into the side of the bottom of the socket.

[0020] The plug can be symmetrical about a first plane. The first plane can be aligned with the central longitudinal axis of the plug. A symmetrical plug allows insertion into the socket regardless of rotation of the plug about its central longitudinal axis, thus providing easier insertion and removal of the plug from the socket.

[0021] For example, a traditional table tennis racket, excluding the rubber layer on the racket face, weighs approximately between 50 and 150 grams. Therefore, even a few grams of weight can significantly affect the weight and / or balance of a racket weighing between 50 and 150 grams. The weight of the insert can be between 1 and 20 grams, 1 and 12 grams, or between 3 and 9 grams. For example, the weight of the insert can be equal to 3 grams, 6 grams, or 9 grams. However, the inserts according to this disclosure are not limited to weighing less than 20 grams, and can weigh, for example, up to 30 grams, 40 grams, or even 50 grams.

[0022] The plug may include one or more materials. For example, the plug may include a second magnetic material. According to another example, the plug may include a second magnetic material and another material. The second magnetic material may be enclosed within, within, or extending through the other material. Alternatively, the other material may be enclosed within, within, or extending through the second magnetic material. It should be understood that this disclosure is not limited to plugs comprising one or two materials, and may include any number of materials, such as three, four, five, or more.

[0023] The socket may further include a cavity and a sleeve, the cavity extending along the central longitudinal axis of the racket into the handle, the sleeve being disposed within the cavity. A plug may be configured to be disposed within the sleeve of the cavity. The shapes of the cavity and the external shapes of the sleeve may be complementary for a substantially matching effect. The shape of the socket can be understood as the internal shape of the sleeve. The internal and external shapes of the sleeve can be understood as the inner and outer surfaces of the sleeve, respectively. The sleeve may comprise a plastic material.

[0024] At least one of the first magnetic material and the second magnetic material can be a magnet. For example, the first magnetic material can be a magnet and the second magnetic material can be a magnetic metal, or the second magnetic material can be a magnet and the first magnetic material can be a magnetic metal, or both the first and second magnetic materials can be magnets.

[0025] A racket may include multiple plugs, each comprising a magnetic material and configured to be disposed within a socket. Each of the multiple plugs may have a different weight than one or more other plugs in the multiple plugs. The multiple plugs may alternatively be referred to as, for example, a set of plugs. The multiple plugs may include, for example, a first plug weighing approximately 3 grams, a second plug weighing approximately 6 grams, and a third plug weighing approximately 9 grams. By having multiple plugs, each with a different weight, the player can easily modify the weight and / or balance of the racket. Attached Figure Description

[0026] This and other aspects of the disclosure will now be described in more detail with reference to the accompanying drawings, which illustrate multiple embodiments of the disclosure.

[0033] Figure 5 A cross-section of the handle of a racket according to an example embodiment of this disclosure is schematically shown. Detailed Implementation

[0034] Figure 1a A ping-pong paddle 1 is schematically shown according to an example embodiment of this disclosure.

[0035] The table tennis racket 1 shown includes a handle 2 and a racket face 3. The handle 2 is connected to the racket face 3 via a base portion 4. The handle 2 includes a socket 5 disposed at an end portion 2' of the handle 2. The socket 5 extends into the handle 2 along the central longitudinal axis 6 of the table tennis racket 1. The socket 5 includes a first magnetic material 7, which may be a magnet, disposed in the socket 5, and is shown in FIG. 1 disposed at the bottom of the socket 5. However, the magnetic material 7 may alternatively be disposed, for example, along the side of the socket 5. The socket 5 is configured to receive a plug (not shown; see example). Figure 2 (as shown in Figure 3), the plug is configured to be disposed in the socket 5. The plug may include a second magnetic material configured to magnetically attract the first magnetic material 7. The socket 5 shown has a chamfered shape, which can be alternatively understood as a tapered shape or an inclined shape.

[0036] This disclosure is not limited to the racket 1 with a racket face 3 and a handle 2 as shown in Figure 1. The shapes of the racket face 3 and / or handle 2 shown in Figure 1 are merely examples, and the racket face 3 and / or handle 2 can be replaced by any type of racket face and / or handle. This fact is... Figure 1b and Figure 1c The example embodiments shown further confirm this.

[0037] Figure 1b A tennis racket 1 according to an example embodiment of this disclosure is illustrated schematically.

[0038] The tennis racket 1 shown is Figure 1a The table tennis racket 1 shown similarly includes a handle 2 and a racket face 3. However, the racket face 3 of the table tennis racket 1 includes an edge in which a string is arranged. The handle 2 includes a truncated string. Figure 1a The socket 5 of the table tennis racket 1 shown is arranged in a similar manner at the end portion 2′ of the handle 2. The socket 5 extends into the handle 2 along the central longitudinal axis 6 of the tennis racket 1. The socket 5 includes a first magnetic material 7, which may be a magnet, arranged in the socket 5. The first magnetic material is shown in Figure 1 arranged at the bottom of the socket 5.

[0039] Figure 1c A badminton racket 1 according to an example embodiment of this disclosure is illustrated schematically.

[0040] The badminton racket 1 shown is similar to... Figure 1a The table tennis racket 1 shown is... Figure 1b The tennis racket 1 shown includes a handle 2 and a racket face 3. Similar to the tennis racket 1, the racket face 3 includes the edge of the badminton racket 1, within which a string is arranged. Furthermore, the handle 2 includes a socket 5 located at the end portion 2' of the handle 2, extending along the central longitudinal axis 6 of the badminton racket 1 into the handle 2, and includes a first magnetic material 7.

[0041] Therefore, in Figures 1a to 1c As shown in the corresponding description above, the concept of having a socket 5 located at the end portion 2' of the handle 2 of the racket 1 and extending along the central longitudinal axis 6 of the racket 1 into the handle 2 is common to many different types of sports rackets. Therefore, Figure 1b and Figure 1a The differences between the example embodiments shown pertain to differences between different types of sports rackets, and not to the implementation of the concepts of this disclosure. Furthermore, it should be understood that this disclosure is not limited to table tennis rackets, tennis rackets, or badminton rackets. Rather, the concepts of this disclosure can be implemented in any type of sports racket.

[0042] Figure 2 The cross-section of the handle 2 and the plug 8 of a racket according to an example embodiment of this disclosure is schematically shown. It should be understood that... Figure 2 The handle 2 shown is part of the racket and provides... Figure 2 The handle 2 shown is for the purpose of providing additional understanding of this disclosure. It should be noted that... Figure 2 This includes the features, elements, and / or functions shown in Figure 1 and described in the relevant text. Therefore, for better understanding, please also refer to Figure 1 and the descriptions associated with it.

[0043] The first diameter D1 of the socket 5, measured at the end portion 2′ of the handle 2, is larger than the second diameter D2 of the socket 5, measured at the bottom 10 of the socket 5. The difference between the first diameter D1 and the second diameter D2 is due to the socket 5 having a chamfered, inclined, or tapered shape. Figure 2 The socket 5 shown has a length L1 along the central longitudinal axis 6, which is measured between the bottom 10 of the socket 5 and the end portion 2′ of the handle 2.

[0044] Figure 2The socket 5 shown includes a first magnetic material 7 disposed at the bottom 10 of the socket 5, thereby establishing the side of the end portion 2' of the first magnetic material 7 facing the handle 2 as the bottom 10 of the socket 5. However, the first magnetic material 7 is not limited to being disposed at the bottom 10 of the socket 5. Therefore, the bottom of the socket 5 may or may not be based on the position or manner in which the first magnetic material 7 is disposed in the socket 5. Therefore, the second diameter D2 and length L1 of the socket 5 may be different based on the arrangement of the first magnetic material 7.

[0045] Figure 2 A plug 8 configured for placement into a socket 5 is shown. The plug 8 includes a second magnetic material configured to magnetically attract a first magnetic material in the socket 5. The shape of the plug 8 is complementary to the shape of the socket 5, wherein… Figure 2 The plug 8 shown is chamfered, inclined, or tapered. The plug 8 has a first diameter D3 measured at a first end portion 8′ and a second diameter D4 measured at a second end portion 8″. The first diameter D3 is larger than the second diameter D4. Furthermore, the plug 8 has a length L2 measured between the end portions 8′ and 8″. The plug 8 can be symmetrical about a first plane 11, which is aligned with the central longitudinal axis 6′ of the plug 8, allowing the plug 8 to have a tapered shape.

[0046] Figure 3a A cross-section of the plug 8 of the racket 1 according to an example embodiment of this disclosure is schematically shown. It should be noted that... Figures 3a to 3c Including, for example Figure 2 The features, elements, and / or functions shown and described in the relevant text. Therefore, for better understanding, please also refer to... Figure 2 And related descriptions.

[0047] The plug 8 has two end portions 8′ and 8″, which may be referred to as the first end portion 8′ and the second end portion 8″. The first end portion 8′ is wider than the second end portion 8″ to allow the plug 8 to be inserted in a wedge shape as shown in Figure 1 and Figure 2 The racket slot shown.

[0048] Figure 3a The plug 8 shown is Figure 2 The differences between the plugs shown and described in the relevant texts are as follows: Figure 3a The plug 8 shown includes one or more flanges 9. Figure 3aThe cross-sectional view shown illustrates a plug 8 including two flanges 9. However, the plug 8 may include one flange 9 extending around the entire plug 8. Furthermore, the plug 8 may include substantially any number of flanges 9 extending from one or more sides of the plug 8. In the following description, the plug 8 will be described as having two flanges 9, but it should be understood that this disclosure is not limited to such embodiments and is done purely for the purpose of enhancing the understanding of this disclosure.

[0049] Flange 9 extends outward from the side of plug 8. The side of plug 8 extends between the second end portion 8″ and flange 9. The extension of the side of plug 8 is at an angle relative to the central longitudinal axis 6′ of plug 8. A surface of each of the flanges 9 (which may be referred to as the top surface) forms part of the first end portion 8′ of plug 8. Another surface 9′ (which may be referred to as the side surface 9′) of each of the flanges 9, opposite to the top surface of the corresponding flange 9, extends between the side of plug 8 and the outermost portion of flange 9. Side surface 9′ provides a smooth transition from the side of plug 8 to flange 9. However, this disclosure is not limited to plug 8 including side surface 9′. For example, one or more flanges 9 may extend substantially perpendicularly from one or more sides of plug 8 relative to the central longitudinal axis 6′ of plug 8.

[0050] The plug 8 has a first diameter D3, which can be measured diagonally across the plug 8 and below the flange 9 of the plug 8. The plug 8 has a second diameter D4, which can be measured diagonally across the second end portion 8″ of the plug 8. The first diameter D3 of the plug 8 can be larger than the second diameter D4 of the plug 8.

[0051] The length L2 of the plug 8 can be measured between the second end portion 8″ of the plug 8 and one or more flanges 9 of the plug 8, along the central longitudinal axis 6′ of the plug 8.

[0052] Figure 3a The plug 8 shown is formed from a single piece of second magnetic material 17.

[0053] Figure 3b A cross-section of the plug 8 of the racket 1 according to an example embodiment of this disclosure is schematically shown.

[0054] Figure 3b The plug 8 shown is Figure 3a The differences between the plugs shown are: Figure 3b The plug 8 shown includes a cavity 19. The cavity 19 extends from the top end portion 8′ of the plug 8 into the plug 8. The cavity 19 may be centered relative to the central longitudinal axis 6′ of the plug 8 and may be rotationally symmetrical. Therefore, Figure 3b Plug 8 and Figure 3aThe difference between the plugs lies in the absence or removal of a portion of the second magnetic material 17. Therefore, Figure 3b The weight of plug 8 is less than Figure 3a The weight of the plugs is determined assuming they are made of the same second magnetic material 17. The size of the cavity 19 is purely exemplary and can be larger or smaller. A larger cavity 19 would make the plug 8 lighter, and correspondingly, a smaller cavity 19 would make the plug 8 heavier. Therefore, the weight of the plug 8 can be determined by providing a cavity 19 of the desired size for the plug 8.

[0055] Figure 3c The plug 8 of racket 1 according to an example embodiment of this disclosure is schematically shown. Figure 3c The plug 8 shown is Figure 3a The difference shown in the plugs is that Figure 3c The plug 8 shown comprises two materials 17 and 18, one of which is a second magnetic material 17. The other material 17, which may be referred to as structural material 18, may be a non-magnetic material. Due to the weight of magnetic materials, a plug 8 comprising one or more magnetic materials may be too heavy. Therefore, to provide a weight-reduced plug 8, the plug 8 may include additional materials 18 that are not magnetic. It should be understood that the plug according to this disclosure is not limited to including materials such as... Figures 3a to 3c It may refer to one or two materials, but may include virtually any number of materials, such as three, four, five or more.

[0056] The second magnetic material 17 is arranged inside the plug 8. Figure 3c In the diagram, the second magnetic material 17 is shown extending between the longitudinal ends 8′ and 8″ of the plug 8. Furthermore, the larger portion of the second magnetic material 17 is arranged closer to the first end portion 8′. It should be understood that... Figure 3c The arrangement of the second magnetic material 17 and structural material 18 shown is purely exemplary. For example, the arrangement of the two materials 17 and 18 can be reversed. Furthermore, the second magnetic material 17 is not limited to extending throughout the entire plug 8. However, arranging the second magnetic material 17 closer to the second end portion 8″ of the plug 8 can provide a stronger magnetic attraction to the first magnetic material of the racket, thus providing a more secure connection. Additionally, centering the second magnetic material 17 within the plug 8 can prevent the plug 8 from making a clicking sound and / or vibrating when it is inserted into the socket.

[0057] Figure 4a A plug 8 configured for insertion into a racket 1 is illustrated schematically according to an example embodiment of this disclosure. It should be noted that... Figure 4a and Figure 4b Including, for example Figure 2 and Figures 3a to 3cThe features, elements, and / or functions shown and described in the relevant text. Therefore, for better understanding, please also refer to... Figure 2 and Figures 3a to 3c And related descriptions. The view of plug 8 is from above the first end portion 8′ of plug 8, such that... Figure 4a Only the first end portion 8' is shown in the figure. It should be understood that the plug 8 extends downwards into the figure. When viewed from above, Figure 4a The plug 8 shown can be as follows: Figures 3a to 3c Any of the plugs shown. Therefore, it should be understood that plug 8 may include a portion extending to the second end (not shown; see example). Figure 2 or Figures 3a to 3c (one or more sides)

[0058] The plug 8 may include a flange 9 extending outwardly from the side of the plug 8. Figure 4a In the middle, this is indicated by a circular dashed line. The dashed line can indicate the position where the side of the plug 8 ends and the position where the flange 9 begins (i.e., extends outward from the side of the plug 8). Figure 4a The flange 9 shown extends outward along the entire side of the plug 8. It should be understood that this disclosure is not limited to... Figure 4a The flange 9 or plug 8 is shown. The plug 8 may include multiple sides, and / or the flange 9 may not extend along all or all of one or more sides of the plug 8. For example, the plug 8 may include one or more sides and may include one or more flanges 9 that may extend along at least one of the one or more sides of the plug 8. Further, the flange 9 may extend along a portion of a side of the plug 8 or along the entire side of the plug 8. The flange 9 may form a portion of a first end portion 8' of the plug.

[0059] Figure 4b A plug 8 configured for insertion into a racket 1 is illustrated schematically according to an example embodiment of this disclosure. Figure 4b The plug 8 shown is Figure 4a The differences between the plugs shown are: Figure 4b The plug 8 shown includes multiple flanges 9. More specifically, Figure 4b The plug 8 shown includes four flanges 9. However, it should be understood that this disclosure is not limited to including four flanges 9, but may include substantially any number of flanges 9, such as one, two, three, four or more. The flanges 9 are arranged along the circumference of the first end portion 8'. The flanges 9 are spaced substantially equally along the circumference.

[0060] Figure 5 A cross-section of the handle 2 of a racket 1 according to an example embodiment of this disclosure is schematically shown. It should be noted that... Figure 5 Including Figure 1 and Figure 2The features, elements, and / or functions shown and described in the relevant text are also referenced. Therefore, for better understanding, please also refer to Figure 1 and... Figure 2 And related descriptions. Figure 5 The handle 2 shown is the same as in Figure 1 and Figure 2 The difference in the handle shown is that Figure 5 The socket 5 of the handle 2 shown includes a cavity 51 and a sleeve 52.

[0061] A cavity 51 extends from the end portion 2′ of the handle 2 along the central longitudinal axis 6 of the racket 1 into the handle 2. A sleeve 52 is disposed within the cavity 51. The sleeve 51 is configured to receive a plug (not shown; see example...). Figures 2 to 4b The shape of cavity 51 and the external shape of sleeve 52 may be complementary for a substantially matching effect. Cavity 51 may include a slot or slit, and sleeve 52 may include a wedge or flange. The slot or slit of cavity 51 and the wedge or flange of sleeve 52 may be complementary for a substantially matching effect. The slot or slit of cavity 51 and the wedge or flange of sleeve 52 can provide a more secure arrangement of sleeve 52 in cavity 51. Furthermore, socket 5 may be provided with fastening means for securing sleeve 52 in cavity 51, such as glue, screws, or bolts. Sleeve 52 may include a plastic material.

[0062] Those skilled in the art will recognize that this disclosure is by no means limited to the preferred embodiments described above. Rather, many modifications and variations are possible within the scope of the appended claims.
