Description

[0001] Cross-reference to related applications

[0002] This application claims priority to U.S. Provisional Patent Application No. 63 / 633,952, filed April 15, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This disclosure generally relates to sound attenuation devices, systems, kits, and methods for the pickleball and the like, and includes, in some aspects, one or more of the following: a racket with sound attenuation characteristics, a sound attenuation accessory structurally configured to engage with the racket, and / or a ball with sound attenuation characteristics. Background Technology

[0004] Pickleball is a racket sport that typically combines elements of tennis, badminton, and table tennis. The playing court is similar in size to a badminton court, with a net separating the two teams. The game uses a perforated plastic ball and a solid racket made of materials such as wood, graphite, and / or composites. Generally, players use their rackets to hit the ball over the net, aiming to land it within the boundary on the other side of the court. Pickleball is a popular sport enjoyed by people of all ages and skill levels. It is known for its relatively simple rules and quick learning curve, making it easy for beginners to pick up while providing depth and strategy for experienced players. In recent years, the sport has experienced exponential growth in popularity worldwide, with many community parks, community centers, and sports clubs featuring dedicated courts.

[0005] However, many people have objections to the noise generated when playing pickleball. The noise issue in pickleball primarily stems from the nature of the sport and the equipment used. Pickleball is typically played on hard surfaces such as asphalt or concrete, which tend to amplify sound. Furthermore, the rackets used in pickleball are usually made of hard materials, which generate and amplify a significant amount of noise upon impact. Several factors contribute to the noise generated during pickleball, including: racket impact, where the ball produces a sharp, distinctive sound due to the impact of the racket against the hard surface; ball impact, as pickleballs are typically made of plastic and have pre-designed holes that, when struck by the racket and / or the ground, create a specific sound; and the court surface, where the hard surface of a pickleball court can reflect and amplify sound.

[0006] Because many pickleball courts are located near residential areas and / or other areas used for other activities (e.g., other workouts, sports or recreational activities, relaxation or leisure activities), the noise from matches can disturb nearby residents and / or others. Furthermore, in areas where multiple pickleball courts are close together, the noise from multiple matches played simultaneously can be amplified and become even more disruptive. For example, noise from pickleball has long been a concern for players and residents living near pickleball courts. In response, some communities have taken measures to mitigate noise, such as installing sound barriers around the courts, scheduling matches at less disruptive times, or simply banning play altogether. Finding a balance between enjoying the sport of pickleball and minimizing its impact on surrounding communities and individuals remains an ongoing challenge for players, organizers, and local authorities.

[0007] The sound attenuation picket ball technology still needs improvement. Utility Model Content

[0037] In general, the apparatuses, systems, and methods disclosed herein relate to sound attenuation devices, systems, kits, and methods for the pickle and the like. That is, the teachings may include features that reduce certain sounds generated when playing pickle, relative to the typical volume of those sounds when playing pickle without using the techniques of the teachings. Furthermore, in some aspects, the teachings may include one or more sound attenuation features for pickle that do not adversely affect and / or hinder standard pickle playing.

[0038] It should be understood that although this disclosure may emphasize the teachings in the context of pickleball, these teachings can be adapted and practiced in other sports and activities, including but not limited to one or more of the following: tennis, badminton, squash, short racket wall, table tennis, etc. Therefore, it should be understood that unless otherwise expressly stated or clearly provided in the context, these teachings are intended to include similar equipment in other sports / activities besides pickleball or in place of pickleball.

[0039] Before describing certain aspects of this teaching, reference will be made to Figure 1A and 1B Describe a pickle ball device based on an example of the prior art.

[0040] Figure 1A and 1B An example of a peak racket is shown. Specifically, Figure 1A shows racket 100 (i.e., "peak racket") and ball 150 (i.e., "peak ball"), while Figure 1B shows several other views of racket 100, wherein each of racket 100 and ball 150 is structurally configured to be used to hit a peak ball according to the prior art. Generally, racket 100 includes a racket face 102 structurally configured to hit ball 150, a handle 104, a throat 106 disposed between racket face 102 and handle 104, and an edge portion 108 on which edge protection devices may be included.

[0041] The racket 100 may be made at least in part of one or more composite materials (e.g., glass fiber and / or carbon fiber). The racket 100 may also be made of one or more of the following materials, or alternatively: wood, graphite, metal (e.g., aluminum), polymer, etc.

[0042] Racket 100 may comply with one or more standard specifications, such as those established by the USA Pickleball Association (e.g., the USA Pickleball Equipment Standards Manual, version 2.0, November 2023, available at https: / / usapickleball.org / docs / eec / Equipment-Standards-Manual.pdf, and incorporated herein by reference). For example, racket 100 may meet certain material standards, such as being made of rigid, incompressible materials; racket 100 may meet certain surface roughness standards, such as not containing holes, dents, rough textures, or any objects or features that allow the player to apply excessive spin to the ball; racket 100 may meet certain reflectivity standards; racket 100 may meet certain size standards, such as the total length and width (including any edge protection and bottom cap) not exceeding 24 inches (60.96 cm), and the racket length not exceeding 17 inches (43.18 cm); racket 100 may meet certain weight standards; and so on.

[0043] Ball 150 can be made of plastic material and may include multiple holes 151 that reduce the speed of ball 150 and produce a characteristic sound when hit. Ball 150 may be structurally configured to bounce relatively well on hard surfaces such as asphalt or concrete, typically used on puck courts. Ball 150 may be made of one or more plastic polymers, such as polyethylene and / or polypropylene. Ball 150 can be an "outdoor" puck ball, which may use harder plastics, such as polyethylene and / or acrylonitrile butadiene styrene (ABS), to withstand harsher conditions such as wind and rough surfaces. Such an outdoor puck ball may have more holes (typically around 40) compared to an indoor puck ball (typically around 26 holes) to minimize wind resistance and ensure a stable flight path. Ball 150 can also be an "indoor" puck ball, which is typically made of softer plastics such as polypropylene to provide better control and more predictable bounce on smooth surfaces. Such an indoor puck ball may have fewer, larger holes to reduce drag and enhance control. The manufacturing process used for the ball 150 can also affect its performance. For example, injection molding can produce a ball with seams and greater elasticity, while rotational molding can produce a faster and more durable seamless ball.

[0044] Ball 150 can comply with one or more standard specifications, such as those developed by the American Pickle Association. For example, Ball 150 can meet certain size standards, such as specifying that the diameter of the ball should be between 2.87 inches (7.29 cm) and 2.97 inches (7.54 cm), with a maximum non-circular diameter variation of no more than + / - 0.020 inches (0.51 mm); Ball 150 can meet certain weight standards, such as specifying that the weight of the ball should be between 0.78 ounces (22.1 g) and 0.935 ounces (26.5 g); Ball 150 can meet certain elasticity standards, such as specifying that when the ball is dropped from a height of 78 inches (198.1 cm) onto a granite slab with a minimum dimensions of 12 inches (30.5 cm) x 12 inches (30.5 cm) x 4 inches (10.2 cm), the bounce height to the top of the ball should be 30 to 34 inches (76.2 to 86.4 cm), with the test conducted at an ambient temperature of 70 degrees Fahrenheit ± 5 degrees Fahrenheit; Ball 150 It can meet certain compression standards, such as specifying that the ball produces an average compression test result of <43 LBF in tests conducted according to (IAW) ASTM F1888-09; the ball 150 can meet certain hardness standards, such as having a hardness of 40 to 50 measured on a hardness tester's D scale at an ambient temperature of 70 degrees Fahrenheit ± 5 degrees Fahrenheit; the ball 150 can meet certain design standards, such as having 26 to 40 holes with spacing conforming to certain characteristics; and so on. Other dimensions and characteristics are also possible or alternative.

[0045] Examples of typical pickle rackets and balls have already been described; now, devices, systems, kits, and methods that provide certain advantageous sound attenuation in pickleball are further described. It should be understood that this teaching can be used while still adhering to one or more pickleball-related standards (such as those described above or any standards known in the sport).

[0046] Figure 2 The image shows a Peak racket with one or more sound attenuation characteristics, based on a representative example. Figure 3 The figures illustrate a Peak racket with one or more sound attenuation features, based on representative examples. Specifically, the rackets shown in these figures may include one or more sound attenuation features such that, when the racket strikes the ball, the sound produced by the impact may be less than the sound produced by the racket lacking such features.

[0047] As shown in the figure, the surface of the racket may include one or more sound-attenuating materials 210, 310. In one aspect, such as Figure 2As shown, sound damping material 210 may include foam, etc. This material may include foam made of one or more thermoplastics, thermoplastic elastomers, and / or other elastomeric materials. For example, this material may include one or more of polyethylene, polyurethane, ethylene-vinyl acetate (EVA), polystyrene, polyolefin elastomers, thermoplastic vulcanizates, etc. This foam material may also or alternatively include one or more closed-cell and open-cell foams (e.g., made of polyethylene or the like). Sound damping material 210 may also include or alternatively include one or more of the following: viscoelastic polymers, elastomers, foams (including, for example, polyurethane, EVA, and silicone-based foams), composite structures comprising rubber and / or thermoplastic layers, and / or advanced materials (e.g., sorbothane, aerogel, fiber-reinforced damping composites, etc.), wherein these materials may be used as continuous layers, fabrics, and / or meshes. Sound damping material 210 may also include or alternatively include special resins with damping properties, which may impregnate carbon fiber components (e.g., the surface of a racket).

[0048] In addition or alternatively, such as Figure 3 As shown, the sound attenuating material 310 may include felt or the like—for example, a material made by weaving, compressing, and pressing fibers together. This felt may be made from one or more of the following: natural fibers (e.g., wool, etc.), synthetic fibers (e.g., acrylic, rayon, etc.), etc. Similar to the materials described above, one or more materials constituting the sound attenuating material 310 may be used as a continuous layer, fabric, and / or mesh.

[0049] Other materials can also be used additionally or as alternatives. For example, generally, almost any material with a relatively low density (e.g., sheet material) can be used, as materials with high porosity help reduce noise without adding significant, unwanted weight to the racket. These materials can have a variety of porosity, density, and / or frequency effectiveness.

[0050] Sound-attenuating materials 210 and 310 may be located on material layers bonded to the racket, for example, adhered to or otherwise bonded to the core or other surfaces of the racket. In some aspects, sound-attenuating materials 210 and 310 completely define one or more layers of the racket. For example, in some embodiments, the core of the racket includes an outer surface, and one or more layers including one or more sound-attenuating materials 210 and 310 are adhered to or otherwise attached to the core to form a sound-attenuating surface of the racket, for example, on its surface and throat portions. In some cases, sound-attenuating materials 210 and 310 may extend to the handle of the racket.

[0051] In some aspects, the sound-attenuating materials 210, 310 themselves define a striking surface by forming at least a portion of the outermost surface of the racket used for striking the ball. In this way, the sound-attenuating materials 210, 310 can be structurally configured to strike the ball in a predetermined manner, which can mimic a conventional picket shot but with enhanced sound attenuation quality. To achieve this, in one aspect, a layer similar to a conventional picket racket surface can be disposed directly beneath the sound-attenuating material 210, 310, or a similar material. Additionally or alternatively, as referenced... Figure 5 As shown in the description of the layers herein, the vibration layer and / or sound attenuation layer may include a textured layer adjacent to it (e.g., on top) to mimic the surface of a standard Peak racket and provide similar coefficient of friction, roughness, and / or spin generation. This textured layer may resemble a conventional (e.g., carbon fiber with resin) striking surface.

[0052] In other aspects, sound-attenuating materials 210 and 310 are disposed beneath a layer defining the striking surface (outermost surface) of the racket. That is, in some aspects, sound-attenuating materials 210 and 310 may be disposed beneath the striking surface of the racket (directly beneath, or indirectly beneath with one or more other layers in between). For example, in one aspect, a textured layer similar to the surface of a conventional Peak racket may be the outermost surface of the racket (e.g., the striking surface is made of one or more of carbon fiber, glass fiber, graphite, composite materials, metal, aramid (Kevlar), or the like), and one or more layers of sound-attenuating materials 210 and 310 are disposed beneath this outermost striking surface, between the striking surface and the core of the racket.

[0053] In some embodiments, the sound-attenuating materials 210, 310 may be part of a replacement surface of a Peak racket. That is, one aspect of this teaching includes an accessory that can convert an existing Peak racket into a sound-attenuating Peak racket (e.g., a "silent racket"). In this way, Peak players can attach this replacement surface to the racket to play in noise-controlled areas, and if needed, they can remove the replacement surface, for example, to play elsewhere, participate in tournaments, etc. Furthermore, this replacement surface can be removed non-destructively, allowing replacements on the racket to be substantially identical to the structure before removal. When formed as part of the replacement surface, double-sided tape or the like can be used, wherein the tape can be configured to leave little or no residue on the racket. Other adhesives, such as glue or epoxy resin, may also be used in conjunction with or as a substitute for the replacement surface. Other connection methods or alternatives may also be used, including one or more of the following: hook and loop fasteners, snap fasteners, magnets, buttons, other mechanical engagement components, clamps, clips, pins, friction fits, snap-fit ​​fits, adhesives, latches, pins, screws, sliders, etc. Such a connection device may, for example, exist on the inner surface of the sound-attenuating materials 210, 310 (e.g., the surface opposite to the top surfaces 202, 302) and may be configured to attach to the core of the racket.

[0054] In some embodiments, sound-attenuating materials 210, 310 may be permanently attached to the Peak racket, for example, as the outermost surface of its surface, or disposed below the outermost surface of its surface (e.g., adjacent to the racket core). Sound-attenuating materials 210, 310 may also be sandwiched within other non-sound-attenuating materials, for example, sandwiched within multiple layers of the Peak racket surface.

[0055] Figure 4 A Peak racket with sound attenuation features is shown according to a representative example. Specifically, the figure illustrates an exemplary embodiment in which a sound attenuation feature (e.g., sound attenuation surface 410) can be placed on an existing racket 400 (e.g., its surface 402) to convert a conventional racket 400 into a sound-attenuated racket 401. Although only one side of the sound-attenuated racket 401 is shown with the sound attenuation surface 410 applied, it is understood that the sound attenuation surface 410 can be located on both surfaces 402 of the existing racket 400 to form the sound-attenuated racket 401. Alternatively, a user can apply the sound attenuation surface 410 to only one surface 402 of the existing racket 400.

[0056] It should be understood that, in one embodiment, the sound attenuation surface 410 may be permanently fixed to the sound attenuation racket 401. Alternatively, in other respects, the sound attenuation surface 410 may be detachably and replaceably attached to the sound attenuation racket 401 – for example, using double-sided tape or any other fastener or connecting device described herein or known in the art.

[0057] Figure 5 A cross-sectional view of a sound attenuation characteristic according to a representative embodiment is shown. For example, sound attenuation characteristic 510 can be compared with... Figure 4 The sound attenuation surface 410 is the same as or similar to, or the same as or similar to, any other sound attenuation feature described herein. Overall, Figure 5 An exploded view is shown of one or more layers that can be used to form the sound attenuation feature 510. Although three layers are shown, more or fewer layers are also possible. One or more of these layers (collectively referred to as all these layers) can provide sound attenuation performance for the Peak racket upon impact with a ball or the like. These layers may include a first layer 511, a second layer 520, and a third layer 530, wherein one or more of these layers may include features configured for sound attenuation, such as any sound attenuation feature described herein.

[0058] The first layer 511 may include a sound-attenuating material. For example, the first layer 511 may include a cotton material or the like, such as thickened pearl cotton. The first layer 511 may also additionally or alternatively consist of one or more other materials that act as sound attenuators. For example, the first layer 511 may include a combination of EVA and polyethylene (PE). Typically, the first layer 511 may have a relatively low density compared, for example, to one or more of the second layer 520 and the third layer 530. In other words, the first layer 511 may have a lower density than each of the second layer 520 and the third layer 530, and / or the first layer 511 may have the lowest density relative to any other layer forming a portion of the racket and / or its surface.

[0059] The first layer 511 can be configured to be attached to the Peak racket by one or more of a variety of methods. For example, the sound attenuation feature may include a fixing mechanism 512, which may be placed in a discrete area beneath the first layer 511 and / or on the racket itself. In some aspects, the fixing mechanism 512 is a layer formed on the bottom surface of the first layer 511 (e.g., the entire bottom surface or a portion thereof). In some aspects, the fixing mechanism 512 includes double-sided tape or the like, for example, formed as a layer beneath the first layer 511. The fixing mechanism 512 may also additionally or alternatively include any of those described herein, such as one or more of the following: glue, tape, paste, hook and loop fasteners, epoxy resin, adhesive coating, nonwoven adhesive fabric, etc. Typically, the fixing mechanism 512 can attach the sound attenuation feature 510 to the surface of the racket by forming an adhesive between the surfaces (e.g., through chemical reaction, surface interaction, and / or mechanical interlocking). The attachment of the sound attenuation feature 510 to the racket surface can be temporary or permanent. In any case, the connection should be able to withstand the forces present in a typical pickle game so that the sound attenuation feature 510 does not detach from the racket surface, either partially or completely, during the game.

[0060] The second layer 520 may include an adhesive or the like between the first layer 511 (e.g., a sound-attenuating layer) and the third layer 530 (e.g., a layer used as the striking surface of a racket in conjunction with the sound-attenuating feature 510). The second layer 520 may also include or alternatively include polyethylene materials, etc. More generally, in some aspects, the second layer 520 may also include or alternatively include sound-attenuating properties or other functions. The second layer 520 (and / or another layer) may also include or alternatively include pressure-sensitive adhesives, thermosetting and / or thermoplastic adhesives, epoxy resins, polyurethane-based adhesives, elastic adhesives, double-sided tapes, and / or any material that provides a predetermined adhesive force. The second layer 520 may also be or alternatively be a textured layer as described herein. For example, the second layer 520 may be an epoxy resin layer on which a texture is disposed. In some cases, the third layer 530 may not be necessary. The second layer 520 may also include or alternatively include polymers, foams, or fibers.

[0061] The third layer 530 may include a layer configured to be placed as the outermost striking surface of the Peak racket face, such as a textured layer. The third layer 530 may be used to replicate something similar to the original texture of the racket, and is intended to be combined with the sound attenuation feature 510 to form a "silent racket" or the like.

[0062] The texture on the third layer 530 can be structurally configured to generate spin upon impact. Without such texture (i.e., when the striking surface is too smooth), increasing spin becomes difficult. On the other hand, excessive texture (i.e., too rough or with too high a coefficient of friction) can introduce excessive spin, creating problems and potentially giving players an unfair competitive advantage. Therefore, in some respects, the third layer 530 can be used to adjust roughness, coefficient of friction (COF), durability (abrasion resistance), and / or aesthetics (e.g., printing logos, text, and / or graphics above or below the texture to alter aesthetics) or the like. Furthermore, in some respects, the third layer 530 can be used to adjust one or more mechanical properties, such as hardness, compressive strength, coefficient of restitution, etc.

[0063] The third layer 530, or more specifically its textured surface, can be made in different ways and can include one or more materials. For example, the third layer 530 can be a fabric with a woven pattern; a patterned thermosetting resin (e.g., a peel-off method); a sandblasted surface; a sandpaper-textured surface with added sand to change roughness; a polymer material with a textured stamping process; and so on.

[0064] In some aspects, this teaching includes an accessory structurally configured to engage with a Peak racket, wherein the accessory provides sound attenuation characteristics. For example, such an accessory may include a sleeve or the like that can be engaged with a Peak racket (e.g., sliding onto the top of an existing Peak racket) to provide a removable and replaceable sound-attenuating surface for playing. As described below... Figure 6-8 An example is shown.

[0065] Based on representative examples, Figure 6 The accessories for Peak rackets are shown. Figure 7 A front view of the accessory that attaches to the Peak racket is shown, and Figure 8 A side view of the accessory that attaches to the Peak racket is shown.

[0066] Accessory 600 may include one or more sound-attenuating materials as described herein, such as foam, felt, rubber, or other elastic materials and / or the like. Accessory 600 may also include, or alternatively include, an outer surface having a textured surface or the like as described herein, for example, a surface structurally configured to strike the ball during a match. Accessory 600 may be structurally configured to engage with a Peak racket to allow a user to play Peakball using the combination of accessory 600 and the racket.

[0067] Accessory 600 can be formed as a sleeve and sized to fit (tightly) onto the Peak racket. That is, accessory 600 can define a pocket whose size and shape are designed to accommodate at least the top of the Peak racket. In some aspects, the size and shape of accessory 600 can be designed such that, when engaged with the Peak racket, accessory 600 covers a large portion of the Peak racket's surface. For example, the size and shape of accessory 600 can be designed to cover the entire surface of the Peak racket. In some aspects, the size and shape of accessory 600 can be designed to cover at least a portion of the Peak racket's throat, for example, covering all areas of the Peak racket's throat in a manner similar to the sound-attenuating materials 210, 310 shown in Figures 2 and 3.

[0068] The accessory 600 may include an edge 640, which may be formed of the same material as one or more other parts of the accessory 600, or may be formed of a different material. In some respects, the edge 640 of the accessory 600, or a portion thereof, is substantially elastic, which can help promote a close fit when the accessory 600 is placed on a Peak racket for use.

[0069] Therefore, accessory 600 can be a sleeve, sized and shaped to fit over at least a majority of the head of the racket, wherein the sleeve includes an edge 640 separating an outer surface (i.e., surface portion 602) and an opposing surface (i.e., the opposing face portion disposed opposite the visible surface portion 602 in the figure), and an opening 642 sized and shaped to selectively insert at least the top of the racket into a pocket defined by the sleeve structure. In this way, the pocket should be understood to include an internal space (i.e., a gap) at least partially occupied by the head of the racket when accessory 600 is applied to the racket. For this purpose, the size and shape of the pocket can be designed to accommodate at least a majority of the head of the racket.

[0070] When accessory 600 is used on the racket, the sleeve can cover the entire head of the racket. When accessory 600 is used on the racket, the sleeve can also, or alternatively, cover at least a portion of the racket throat. As discussed herein, the sleeve is removable and replaceable on the racket.

[0071] In some aspects, one or more of the opening 642 and the pocket are extendable to accommodate at least the top of the racket. Similarly, one or more of the opening 642 and the pocket may be retractable to conform to the shape of the racket when placed on it. The extendable nature of the opening 642 and / or the pocket can be achieved by using an elastic material (such as elastic fabric or strap) incorporated into the structure. For example, this elasticity can allow the opening 642 to temporarily extend to accommodate rackets of various sizes and shapes, and then return to its original shape to ensure a tight fit. The opening 642 and / or the pocket may also have pleats or gathered sections that can unfold to increase capacity when the racket is accommodated, and then fold back after the racket is inserted to reduce excess material. In some embodiments, the opening 642 and / or the pocket may include adjustable elements such as drawstrings, hook-and-loop fasteners, or snaps, which allows the user to customize the fit according to the shape and size of different rackets. The retractable aspect of the opening 642 and / or the pocket can be facilitated by using a flexible yet durable material that can easily conform to the contours of the racket. This fit can help maintain the racket's original hitting characteristics while providing the desired sound attenuation. The material may include strategically placed creases or folds that allow it to fold neatly around the edges and corners of the racket. In some cases, stretchable and retractable features can work together, with the opening 642 stretching to allow easy racket insertion and then retracting with the pocket to create a smooth, wrinkle-free surface on the racket. This design helps ensure that the sound attenuation accessory does not interfere with the racket's performance during a shot. The stretchable and retractable features also facilitate easy application and removal of the sound attenuation accessory 600, allowing athletes to quickly switch between sound attenuation and non-sound attenuation as needed. Furthermore, these features may facilitate storage of the accessory 600 when not in use, as it can fold into a more compact form for easy transport or storage. Other constructions of the sleeve are also possible or alternatively possible.

[0072] Edge 640 may be formed of the same material as one or more other parts of accessory 600, or it may be formed of a different material. Edge 640 may be sufficiently flexible to provide a predetermined fit when accessory 600 is placed on the racket for use. Therefore, edge 640 may also, or alternatively, include any of the elastic features and functions described above with respect to opening 642 and / or pocket. Generally, including elastic components allows edge 640 to stretch and conform to the shape of the racket while maintaining tension to secure accessory 600 in place.

[0073] In some respects, the elasticity of the edge 640 can vary along different sections of the accessory 600. For example, greater elasticity may be present at corners or areas with complex curvature (such as the throat area) to ensure a tight fit in these areas. The edge 640 may also have progressive elasticity, with greater stretch at the opening for ease of use and less stretch along the sides to maintain a firm fit during impact. This inherent elasticity of the edge 640 allows the accessory 600 to adapt to rackets of slightly different sizes and shapes while still providing a generally consistent intended fit. This adaptability can be particularly useful given the differences in racket designs between different manufacturers or models. In some embodiments, the edge 640 may include other features to enhance its fit. For example, it may include adjustable elements such as drawstrings, elastic cords, or hook-and-loop fasteners, allowing the user to fine-tune the fit of the accessory 600 to their specific racket. The elasticity of the edge 640 may also contribute to the overall durability and lifespan of the accessory 600. By allowing for a degree of flexibility and movement, the flexible edge helps prevent tearing or damage that could occur in a more rigid design, especially when reusing and removing the accessory 600. Furthermore, the flexible edge 640 ensures consistent contact between the accessory 600 and the racket surface, thus helping to maintain the sound attenuation characteristics of the accessory 600. This close fit prevents the formation of air gaps or loose areas that could reduce sound attenuation.

[0074] Therefore, as described and illustrated herein, embodiments of this teaching may include noise control accessories for a Peak racket, such accessories comprising: sound attenuation material 210 of FIG. 2; sound attenuation material 310 of FIG. 3; sound attenuation surface 410 of FIG. 4; sound attenuation feature 510 of FIG. 5; accessory 600 of FIG. 6-8; or similar accessories. Noise control accessories typically include an outer surface and sound attenuation components.

[0075] The outer surface can be structurally configured for use with the ball. For example, this outer surface may correspond to the top surface 202 of FIG. 2, the top surface 302 of FIG. 3, the surface 402 of FIG. 4, the third layer 530 of FIG. 5, and / or the surface portion 602 of FIG. 6-8, or the like. In some aspects, the outer surface includes the sound-attenuating material itself (e.g., the first sound-attenuating material described below) – examples of which may include… Figure 2 and 3The racket or similar object shown. Alternatively, the outer surface may include a layer defining the racket's striking surface, which is coupled to and covers at least a majority of the racket's sound attenuation component. For this purpose, the outer surface may include one or more of carbon fiber, glass fiber, graphite, composite materials, metals, etc. In some aspects, the outer surface may include a textured surface structurally configured to strike a ball and cause the ball to spin upon impact.

[0076] Sound attenuation components can be structurally configured to engage directly or indirectly with the surface of the racket. That is, sound attenuation components can be directly disposed on the surface of the racket, wherein such surface can include: the striking surface of the racket (e.g., where the component is modified to or otherwise placed on the manufactured racket), the core of the racket, or the surface engaged therewith (e.g., adding the component during the manufacturing process before the racket is made, or adding the component to a racket whose surface has been removed during post-manufacturing finishing processes, or similar cases).

[0077] The sound attenuation component may include a first sound attenuation material, the density of which is lower than the density of the racket's surface and / or other parts of the racket. The first sound attenuation material may correspond to, for example... Figure 2 Sound attenuation material 210 Figure 3 Sound attenuation material 310 Figure 4 Sound attenuation surface 410, reference Figure 5 The sound attenuation feature 510, as shown by one or more layers (e.g., the first layer 511, or one or more other layers), is typically included in Figure 6-8 The materials in or above of accessory 600, and the like. Generally, the first sound damping material may be structurally configured to reduce noise generated when the racket strikes the ball directly relative to the surface of the racket. For example, the first sound damping material may include one or more of the following: foam materials (e.g., foam materials comprising multiple open pores, and / or foam materials comprising multiple closed pores), felt materials, elastic materials, etc.

[0078] This accessory can be configured as a sleeve, the size and shape of which are designed to cover at least most of the head of the racket—see example above. Figure 6 –8. In these aspects, the accessory may include a component that can slide onto or otherwise attach to the racket. In other aspects, the accessory may be configured as a flip cover attached to the head of the racket, an assembly releasably engaged with the racket surface, an assembly permanently engaged with the racket surface, an assembly disposed below the striking surface of the racket, etc. In this way, the accessory may include two or more components adapted to the racket.

[0079] The accessory may include a lower surface structurally configured for mounting and direct attachment to a surface of the racket—for example, an existing striking surface, a core, or other portion as described herein. This lower surface may correspond, for example, to the opposite side of the sound-attenuating material 210 attached to the racket as shown in FIG. 2, the opposite side of the sound-attenuating material 310 attached to the racket as shown in FIG. 3, the lower side of the sound-attenuating surface 410 attached to the racket, the lower layer of the sound-attenuating feature 510 shown in FIG. 5, or the like. For example, the lower surface may include a fixing mechanism, such as… Figure 5 The fastening mechanism 512. Such a fastening mechanism can be any of those described herein, and may include, for example, one or more of the following: a layer formed along the lower surface, double-sided tape, or the like. The fastening mechanism may also include, or alternatively include, one or more of the following: hook and loop fasteners, snaps, magnets, mechanical engagement components, etc.

[0080] In some respects, the lower surface includes an adhesive. In some respects, the lower surface is structurally configured for removal from the racket after attachment (e.g., in a non-destructive manner). In other respects, the lower surface is structurally configured for permanent attachment to the racket surface.

[0081] Sound attenuation components may include multiple layers. For example, these layers may correspond to the multiple layers shown in sound attenuation feature 510 in FIG. 5. However, it should be understood that any other sound attenuation component described herein (e.g., the component referring to FIG. 2-4 and FIG. 6-8) may also include or alternatively include the multiple layers described herein. In this way, in some aspects, a sound attenuation component may include multiple layers comprising a first layer containing a first sound attenuation material and a second layer containing a second material. The second material may be a sound attenuation material. The second material may also include or alternatively include a lower density than the racket surface (or another part of the racket, such as its core). In some aspects, the second layer may include an adhesive. And in some aspects, the second layer may include the outer surface of a fitting.

[0082] Multiple layers may also include a third layer. For example, in some aspects, the density of the first sound-attenuating material in the first layer is less than that of each of the second and third layers, the second layer is disposed above the first layer, the second material of the second layer includes at least one of polyethylene material and adhesive, and the third layer defines the outer surface of the fitting. In some cases, the fitting may also include a fourth layer. The fourth layer may include a fixing mechanism, such as any fixing mechanism described herein.

[0083] As described herein, in some respects, a Peak racket may include sound attenuation features disposed on or within the racket (such as any sound attenuation features described herein). For example, one or more sound attenuation features may be present between the core of the racket (or another internal structure, such as the frame) and the outermost surface defining the surface of the racket. For example, the racket may include: a first surface; a second surface; a core (or another internal structural component, wherein it should be understood that the description of the core herein should include other similar structural components) disposed between the first and second surfaces; and sound attenuation features disposed between (i) the core and the first surface and (ii) the core and the second surface.

[0084] The sound attenuation component may include a first sound attenuation material (such as any sound attenuation material described herein) with a lower density than each of the first surface, second surface, and core of the racket. The first sound attenuation material may be structurally configured to produce lower noise when the racket strikes the ball compared to direct impacts between the first and second surfaces.

[0085] The sound attenuation component may also include multiple layers, including a first layer comprising a first sound attenuating material and a second layer comprising a second material. The second material may be a sound attenuating material. The second layer may include an adhesive. The multiple layers may also include a third layer. The third layer may define the surface of the racket. Alternatively, another layer of the multiple layers may define the surface of the racket.

[0086] Figure 9 This is a flowchart of a noise control method 900 for pickleball or similar sports, based on a representative example. Method 900 may utilize any one or more aspects of the teachings described herein, such as any aspect shown and described with reference to Figures 2-8.

[0087] As shown in step 902, method 900 may include applying a noise control accessory to a Peak racket, the racket including a core (or other internal structural component, such as a frame, etc.) disposed between its two surfaces. The noise control accessory may include any noise control accessory described herein. For example, the noise control accessory may include an outer surface structurally configured for hitting a ball, and a sound attenuation component structurally configured to bond directly or indirectly (e.g., through intermediary materials and / or layers such as adhesives) to the surface of the Peak racket. The sound attenuation component assembly may include a first sound attenuation material with a density lower than that of the Peak racket surface. The first sound attenuation material may be structurally configured to reduce noise generated when the ball is struck directly relative to the surface of the Peak racket during impact with the ball.

[0088] In some aspects, applying a noise control accessory to a Peak racket includes sliding the noise control accessory onto the head of the Peak racket. For example, the noise control accessory may be a sleeve whose size and shape can fit at least a majority of the Peak racket head. In one example aspect, the sleeve includes an edge separating an outer surface and an opposing surface, and an opening whose size and shape are designed to selectively insert at least the top of the Peak racket into a pocket defined by the structure of the sleeve. Furthermore, in a further example aspect, applying a noise control accessory to a Peak racket may also include extending one or more of the opening and pocket to receive at least the top of the Peak racket, and contracting the opening and / or pocket to conform to the shape of the Peak racket when the opening and / or pocket is placed on the Peak racket. Additionally or alternatively, applying a noise control accessory to a Peak racket may include extending the edge to receive the Peak racket within the pocket, and contracting the edge to conform to the shape of the Peak racket when the noise control accessory is placed on the Peak racket.

[0089] Alternatively, applying noise control accessories to Peak rackets may include directly mounting and attaching the noise control accessories to at least one of the two sides of the Peak racket.

[0090] As shown in step 904, method 900 may include using a Peak racket with applied noise control accessories to hit the ball with the outer surface of the noise control accessories (e.g., hitting the ball with the racket after the noise control accessories have been applied to the Peak racket). As described herein, this can produce less noise compared to hitting the ball with a racket without using the noise control accessories.

[0091] As shown in step 906, method 900 may include removing a noise control accessory from the Peak racket. For example, this might include removing the sleeve by sliding it off the Peak racket. This may also, or alternatively, include pulling and / or peeling the noise control accessory from at least one of the two sides of the Peak racket. Removal may include non-destructive removal, thereby allowing the noise control accessory on the racket to be replaced with one that is substantially identical in structure to its original state before removal.

[0092] Figure 10 A pickle ball with one or more sound attenuation characteristics is shown according to a representative example. The ball 1000 may include a first part 1010 and a second part 1020.

[0093] The first portion 1010 of ball 1000 may include a standard pickball shape and material, such as any shape and material described herein (e.g., conforming to one or more third-party standards). Thus, in one aspect, the first portion 1010 is simply a standard pickball, such as an off-the-shelf ball or the like. In this way, the first portion 1010 may be an existing pickball. Therefore, ball 1000 may include flight and elasticity characteristics conforming to one or more predetermined pickball standards, such as those described herein or known in the art.

[0094] Specifically, the first portion 1010 may be formed of a rigid plastic material or the like. The first portion 1010 may have a generally spherical shape, where "generally" as used herein means that, when viewed with the naked eye, the sphere 1000 appears spherical to the average human user, and / or certain inconsistencies (e.g., due to manufacturing tolerances) do not significantly affect the overall spherical appearance of the sphere 1000. The first portion 1010 may include a plurality of holes 1012 surrounding its surface 1011. The plurality of holes 1012 may lead to a generally hollow interior portion. It should be understood that "generally" as used herein means that the majority of the interior of the sphere 1000 is without material.

[0095] The second portion 1020 of the ball 1000 may include a material layer arranged in a predetermined pattern and having a predetermined size and shape. This material layer may be applied to the outer surface 1011 of the first portion 1010 to form the second portion 1020 thereon and to provide sound attenuation properties to the ball 1000. This material layer (i.e., the sound attenuating material) may be made of foam material, felt material, elastomer material, elastomer (e.g., thermoplastic or thermosetting), coating material, etc. Generally, the material layer may be structurally configured to attenuate vibrations caused by the ball 1000 impacting a surface (e.g., a Peak racket, a Peak court surface, etc.) and to absorb at least a portion of the sound generated by such impact. Therefore, the material layer may include any vibration attenuation and / or sound attenuation material described herein, such as those referenced herein. Figure 2-8 Any one or more of them.

[0096] Therefore, in some aspects of this teaching, the second portion 1020 may include a sound-damping material at least partially disposed on the surface 1011 of the first portion 1010. The density of the sound-damping material may be lower than that of the rigid plastic material of the first portion 1010. Relative to the first portion 1010 on which the second portion 1020 is not disposed (i.e., relative to a conventionally available pickball), the sound-damping material may also, or alternatively, be structurally configured to reduce noise generated during impact with a racket or striking surface.

[0097] In some respects, the second part 1020 is permanently attached to the first part 1010. For example, in manufacturing such a ball 1000, the first part 1010 may be formed using a first material (e.g., a hard plastic or the like), and the second part 1020 may be formed on the first part 1010 using a second material (e.g., a foam material or the like). This may include, for example, a two-step injection molding process (i.e., two injections of different injection materials) or similar manufacturing techniques. Other manufacturing techniques are also feasible or alternative.

[0098] The second portion 1020 may include a predetermined pattern made of a sound-attenuating material disposed on the surface 1011 of the first portion 1010. The predetermined pattern may be one or more of a woven pattern, a cross-shaped pattern, a mesh pattern, or similar patterns. The predetermined pattern may cover the entire surface 1011 of the first portion 1010. The second portion 1020 may include multiple regions that cover at least a portion of one or more of the plurality of holes 1012. Alternatively, the second portion 1020 may not cover any portion of the plurality of holes 1012.

[0099] In Figure 10, the second portion 1020 is shown as being disposed on the outer surface of the first portion 1010, but it should be understood that the second portion 1020 may also or alternatively be disposed on the inner portion of the first portion 1010—see, for example, Figure 13 described below.

[0100] Figure 11 illustrates an accessory for a ball and a pickle, according to a representative example. Specifically, the figure shows a cover 1120 forming the accessory for ball 1110, wherein the cover 1120 is applied to ball 1110 to improve the sound attenuation performance of ball 1110. That is, the cover 1120 can be attached to ball 1110 (e.g., the cover 1120 essentially wraps around ball 1110) to provide a silent version of the pickle.

[0101] Therefore, in one aspect, the second part (e.g., cover 1120) is detachable and replaceable relative to the first part (e.g., ball 1110). In other words, the second part can be detachably attached to the first part. For example, the second part can be a cover 1120 that can be added to an existing pickle, i.e., selectively applied to and / or removed from the first part. For this purpose, the second part itself can be an accessory that the user can add to the pickle to create a ball that is relatively quiet compared to a conventional pickle. For example, the second part can be formed as a one-piece cover 1120 with a cut (or other type of opening 1122, etc.) that is structurally configured to accommodate the first part such that the second part substantially encloses the ball 1110.

[0102] The cover 1120 may have greater elasticity relative to the ball 1110. In such an aspect, the tension and / or elasticity of the material used to form the second part can maintain a tight fit around the ball 1110, and / or adhesives may be used. The cover 1120, or more generally, the second part, may be a single component. Alternatively, the second part may be formed as more than one component, for example, two components (e.g., two halves / hemispherical parts) structurally configured to be attached around the pick ball using some type of adhesive and / or snap-fit ​​system. In other words, the cover 1120, or more generally, the second part, may include at least two components structurally configured to be attached to each other around the first part. There may also be more components. These components may be attached together by mechanical engagement (e.g., interlocking mechanical components, snap-fit, friction fit, by nesting with each other, etc.). In some aspects, adhesives may be used to join the second part to the first part.

[0103] Figure 12 shows a cross-sectional view of a pickball having one or more sound attenuation features according to a representative example, the pickball having sound attenuation features disposed on the outer portion 1214 of the ball, and Figure 13 shows a cross-sectional view of a pickball having one or more sound attenuation features according to a representative example, the pickball having sound attenuation features disposed on the inner portion 1316 of the ball.

[0104] That is, such as Figure 12 As shown, the surface of the first portion 1210 (on which the second portion 1220 is disposed) can be the outer surface of the sphere (i.e., along the outer side 1214 of the sphere). Alternatively, as... Figure 13 As shown, the surface of the first portion 1310 (on which the second portion 1320 is disposed) may be the inner surface of the ball, or the second portion 1320 may be formed within the interior 1316 of the ball. For example, in one aspect, both the inner and outer surfaces of the ball include at least a portion of the second portions 1220, 1320 disposed thereon. Alternatively, only one of the inner or outer surfaces of the ball may include at least a portion of the second portions 1220, 1320 disposed thereon. As described herein, the second portions 1220, 1320 may be structurally configured to dampen vibrations caused by impacts between the ball and the racket, the striking surface, the net (or a portion thereof), or the like.

[0105] It should be understood that the second portion 1320 shown in Figure 13 is engaged with the inner surface of the sphere's interior 1316. Therefore, in this respect, the majority of the interior portion 1316 remains unmaterialized, i.e., the sphere remains substantially hollow. However, in one aspect, it should be understood that other portions of the sphere's interior portion 1316 may also be additionally or alternatively filled with the material of the second portion 1320, or a similar sound-dampening material. Therefore, some aspects may involve spheres that are not substantially hollow.
