DETAILED DESCRIPTION

Various non-limiting embodiments of the present disclosure will now be described to provide an overall understanding of the principles of the structure, function, and use of impact dissipating balls disclosed herein. One or more examples of these non-limiting embodiments are illustrated in the accompanying drawings. Those of ordinary skill in the art will understand that the balls and methods specifically described herein and illustrated in the accompanying drawings are non-limiting embodiments. The features illustrated or described in connection with one non-limiting embodiment may be combined with the features of other non-limiting embodiments. Such modifications and variations are intended to be included within the scope of the present disclosure.
The presently disclosed embodiments are generally directed to impact dissipating balls, methods of using impact dissipating balls, and methods of manufacturing impact dissipating balls. More specifically, the presently disclosed embodiments are generally directed to soccer balls that can be constructed with one or more layers, sections, or portions of impact absorbing, impact dissipating materials, or impact dissipating structures/geometries, referred to generally herein as padding or a padding layer. The particular type and/or arrangement or placement of padding can vary based on a variety of factors, such as style of soccer ball, size of soccer ball, the manufacturing process of the soccer ball, expected levels of impact, quality of the soccer ball, regulations with which the ball is intended to comply, and so forth. As described in more detail below, in some embodiments, a soccer ball can be manufactured from multiple layers wrapped or otherwise formed around an airtight bladder or other type of core. In accordance with the present disclosure, padding can be disposed on the outer surface and/or in between various layers during the manufacturing process. This padding can generally serve to dissipate impact to a player when the player strikes the ball, such as using their head. The padding can also serve to dissipate impact when a player is inadvertently hit with the ball, such as in the face or other parts of the head.
In some embodiments, soccer balls incorporating padding satisfy appropriate regulations such as those promulgated by Fédération Internationale de Football Association (FIFA). As such, in some embodiments, soccer balls incorporating padding can be spherical, made of leather or other suitable material, of a circumference of not more than 70 cm and not less than 68 cm, not more than 450 g in weight and not less than 410 g at the start of the match, and a of a pressure equal to 0.6-1.1 atmosphere (600-1100 g/cm²) at sea level. Soccer balls for youth games can have smaller dimensions and weights. As is to be appreciated, impact dissipating balls in accordance with the present disclosure can be utilized for other sporting endeavors, such as sports in which players typically impact the ball with their head. For such sports, such as futsal, the impact dissipating balls can be manufactured with padding while retaining relevant competition ball requirements. With regard to futsal balls incorporating padding during the manufacturing process, for example, the futsal ball can be spherical, made of leather or other suitable material, of a circumference of not less than 62 cm and not more than 64 cm, not less than 400 grams nor more than 440 grams in weight at the start of the match, and of a pressure equal to 0.4-0.6 atmosphere (400-600 g/cm²) at sea level. To the extent that FIFA regulations may vary, or the ball will be used for sports having different requirements, impact dissipating balls can be manufactured in accordance with the present disclosure to comply with those regulations and/or requirements.
Reference throughout the specification to “various embodiments,” “some embodiments,” “one embodiment,” “some example embodiments,” “one example embodiment,” or “an embodiment” means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment. Thus, appearances of the phrases “in various embodiments,” “in some embodiments,” “in one embodiment,” “some example embodiments,” “one example embodiment, or “in an embodiment” in places throughout the specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures or characteristics may be combined in any suitable manner in one or more embodiments.
Referring now to FIGS. 1-3, example partial cutaway views of simplified soccer balls 100, 200, and 300 are depicted showing various internal layers thereof. As is to be appreciated, soccer balls 100, 200, and 300 can schematically represent relatively inexpensive soccer balls, as may be designed for recreational or some lower levels of competitive play. Soccer balls 100, 200, and 300 depicted in FIGS. 1-3 can also schematically represent high quality, relatively expensive soccer balls designed for high levels of competitive play. Highest quality soccer balls, for example, are typically hand stitched with a 5-ply twisted polyester cord, mid-priced balls are typically machine-stitched, and low end balls are typically glued together. Nevertheless, soccer balls manufactured in accordance with the present disclosure can incorporate one or more impact dissipating padding layers.
Referring first to FIG. 1, a soccer ball 100 is shown having a core 102. In some embodiments, the core 102 is an airtight bladder which is filled with air to appropriately pressurize the soccer ball 100 for gameplay. A padding layer 120 is in contact with the core 102 and either partially or entirely surrounds the core 102. As schematically depicted by lining layer 104, one or more layers of lining can be placed between the padding layer 120 and the cover 106. The composition and number of lining layers 104 can vary. As compared to conventional balls, the number of layers 104 and/or the size of the core 102 can be reduced to accommodate the thickness of the padding layer 120, as to maintain the total outer dimension of the soccer ball 100 at the desired size. In some embodiments, lining layer(s) 104 are polyester and/or cotton bonded (laminated) together to give the ball strength, structure and bounce. In some embodiments, the lining layer(s) 104 is a fiber-reinforced composite. Professional soccer balls or other higher end balls usually have four or more layers of lining. Promotional or practice balls may be constructed with less layers of lining.
The cover 106 can be made from, for example, synthetic leather made from PU (polyurethane) and PVC (poly vinyl chloride). As is to be appreciated, there are many variations of synthetic leather that can be used for cover 106, such as AI-2000, Japanese Teijin Cordley, Microfiber, English Porvair, Korean Ducksung, Leather Art Pakistan Synthetic Leather, and PVC (poly vinyl chloride). The highest quality soccer balls used in competition and by professionals are typically produced by using AI-2000, Cordley, Ducksung, Mircofiber or other types of PU synthetic leather. Promotional soccer balls or practice balls are usually constructed with Polyvinyl Chloride(PVC) or rubber (molded or stitched) covers. For indoor soccer balls, the cover 106 can be made with a felt material similar to what is used on a tennis ball.
The cover 106 can comprise of a plurality of panels, the different segments that make up the outside covering of the ball, having similar or different shapes. The number of panels can vary for each design. A 32-panel ball is an example type of soccer ball, which is essentially a Buckminster Ball consisting of 20 hexagonal (six sided) and 12 pentagonal (five sided) surfaces. Panels of cover 106 can be stitched, glued, or thermally molded, such that when the soccer ball 100 is inflated, it is nearly a perfect sphere. Other traditional designs are 18 and 26-panel constructions, used in various professional leagues, including Major League Soccer, Scottish and English leagues. Some designs use less panels, such as 6 paneled soccer balls that are thermally bonded and do not utilized stitching.
While FIG. 1, depicts the padding layer positioned between a liner layer 104 and the core 102, other arrangements can be utilized, some examples of which are depicted in FIG. 2 and FIG. 3. FIG. 2 depicts a soccer ball 200 having a cover 206, lining layer 204 and an inner core 202. These components can be similar, for example, to the similar components in FIG. 1. In this embodiment, a padding layer 220 is positioned between the cover 206 and the lining layer 204. In other configurations, multiple padding layers can utilized, such as a first padding layer positioned between the cover 206 and the lining layer 204 and a second padding layer (not shown) positioned between the lining layer 204 and the inner core 202. In some embodiments, the padding layer 220 can serve as one or more of the lining layers 204, thereby eliminating the need for the lining layer 204 or at least reducing the number of layers included in the lining layer 204. FIG. 3 depicts a soccer ball 300 having similar components to the soccer balls 100, 200 of FIGS. 1-2. In this embodiment, however, the padding layer 320 is the outermost layer of the soccer ball 300, such that the padding layer 320 will be directly impacted by players during gameplay. The padding layer 320 can be separate from the cover 306 or laminated therewith. In some configurations, the padding layer 320 is stitched, glued, or thermally bonded to the cover 306 (which may serve as a part of the lining layer). Additionally or alternatively, the soccer ball 300 can include the lining layer 304 and the padding layer 320 is applied directly to the lining layer 304. As with other embodiments, the inner core 302 can be positioned at the center of the soccer ball 300. The padding layer 320 can be comprised of multiple panels, as described above with regard to the cover 106.
While FIGS. 1-3 schematically depict soccer balls for the purposes of illustration, it is to be appreciated other types of multi-layer sports balls can be manufactured using similar techniques to provide impact dissipating functionality. Such functionality may be desirable for sports using balls that are particularly hard (i.e., baseballs) and/or balls that travel at high rates of speed (i.e., Jai alai). All such impact dissipating sports balls are intended to be covered by the present disclosure.
The padding layer utilized by soccer balls in accordance with the present disclosure, such as padding layers 120, 220, and 320, and described in more detail below, can be comprised of any suitable material that provides the desirable characteristics and response to impact. For example, the padding layer can comprise one or more of the following materials: thermoplastic polyurethane (available, for example, from Skydex Technologies), military-grade materials, impact absorbing silicone, D30® impact absorbing material, impact gel, wovens, non-wovens, cotton, elastomers, IMPAXX® energy-absorbing foam (available from Dow Automotive), DEFLEXION shock absorbing material (available from Dow Corning), styrofoam, polymer gels, general shock absorbing elastometers, visco-elastic polymers, PORON® XRD impact protection (available from Rogers Corporation), Sorbothane® (available from Sorbothane Inc.), Neoprene (available from DuPont), Ethyl Vinyl Acetate, impact-dispersing gels, foams, rubbers, and so forth. In some embodiments, the padding material can be auxetic, such as Armourgel S2® (available from Armourgel Limited). As such, the padding material can include geometries that structurally define a plurality of deformable voids between two layers of the soccer ball. During impact, the padding material (and the voids defined thereby) can deform proximate to the area of impact to dissipate the impact. The deformable voids can be visually concealed from an observer of the ball, such that the ball visually emulates a conventional soccer ball. In some embodiments, the padding material can also locally densify as the load rises.
The padding layer can be attached to one or more layers (such as the core 202, the cover 206 and/or lining layer 204 of FIG. 2, for example). In some embodiments, the padding layer 340 can be generally disconnected and “floating” between the layers. In some embodiments, the padding layer is coupled (i.e., glued, laminated, stitched, etc.) to one more components of the soccer ball. In some embodiments, padding layers in accordance with the present systems and methods can comprise a rate dependent material, such as a rate dependent low density foam material. Examples of suitable low density foams include polyester and polyether polyurethane foams. In some embodiments, such foams to have a density ranging from about 5 pounds per cubic foot (pcf) to about 35 pcf), more particularly from about 10 pcf to about 30 pcf, and more particularly still from about 15 pcf to about 25 pcf. PORON® and PORON XRD® are available from Rogers Corporation, which are open cell, microcellular polyurethane foams, is an example of one suitable rate dependent foam. However, in order to provide impact resistance, the padding layer can be any suitable energy absorbing or rate dependent materials. As such, other rate dependent foams or other types of materials can be used without departing from the scope of the present disclosure.
FIGS. 4-6 depict soccer balls having internally positioned padding layers, which are shown in phantom for the purposes of illustration. Referring first to FIG. 4, soccer ball 400 comprises a plurality of cover panels 402 that are joined to collectively form the outer cover. While FIG. 4 depicts a soccer ball having hexagonal and pentagonal cover panels 402, it is to be readily appreciated that the particular style of panels can vary without departing from the scope of the present disclosure. In this embodiment, the padding layer is comprised of a plurality of padding panels 404 that are generally shaped commensurately with the cover panels 402. FIG. 5 depicts an example soccer ball 500 having a plurality of cover panels 502. The padding panels 504 are generally triangularly shaped and attached together to form a sphere. FIG. 6 depicts an example soccer ball 600 having a plurality of cover panels 602. In this embodiment, the various padding panels 604 collective form a sphere, with each padding panel 604 spanning a plurality of cover panels 602.
Referring now to FIGS. 7-14, various non-limiting example cover panel and padding panel arrangements are depicted. While the cover panels and/or padding panels are pentagonal in the illustrated embodiments, it is to be readily appreciated that a variety of different shaped cover panels and/or padding panels can be utilized without departing from the scope of the present disclosure. FIG. 7 depicts an embodiment in which a padding panel 704 serves as the cover panel. A plurality of padding panels 704 can be joined to form the outer surface of a soccer ball, such as the soccer ball 300 illustrated in FIG. 3. FIG. 8 depicts a cover panel 802 that is coupled to a padding panel 804 that is substantially the same shape (i.e., coextensive). Such arrangement can be manufactured using a variety of suitable processes. For example, a sheet of the material for the cover panel can be joined to a sheet of padding material and then cut into the component as shown in FIG. 8. Alternatively, the cover panel 802 can be formed separately from the padding panel 804 and then subsequently coupled using a suitable process, such as gluing, stitching, and so forth. In FIG. 8, the cover panel 802 is positioned on the exterior of the padding panel 804, such that the cover panel 802 forms the exterior surface of a soccer ball. FIG. 9 depicts a similar arrangement as FIG. 8, with the padding panel layer 904 being coextensive with the cover panel layer 902. In this embodiment, however, the padding panel 904 forms the exterior surface of a soccer ball. Referring now to FIG. 10, a multi-layered arrangement is depicted. In this embodiment, a padding panel 904 is positioned between a first cover panel 902 and a second cover panel 906. In some embodiments, the three layers are laminated to form a unitary panel that can be used to form the outer covering of a soccer ball.
While FIGS. 7-10 depict padding panels as being generally coextensive with cover panels, this disclosure is not so limited. Referring to FIG. 11, for example, a padding panel 1104 is coupled to a cover panel 1102 and the overall dimension of the padding panel 1104 is less than the dimensions of the cover panel 1102. An overhang is formed around the periphery of the cover panel 1102, which can be utilized, for example, during the manufacturing process. In one embodiment, the overhang is utilized when attaching adjacent cover panels 1102 (i.e., to receive stitching and/or glue). FIG. 12 is similar to FIG. 11 in that an overhang is formed on the cover panel 1202 due to the smaller size of the padding panel 1204. In this embodiment, however, the padding panel 1204 is positioned on the exterior side of the cover panel 1202.
FIGS. 13-14 depict example arrangements in which a padding panel is coupled to multiple cover panels. Referring first to FIG. 13, a first cover panel 1302 and an adjacent cover pane 1306 are both coupled to a surface of a padding layer 1304. FIG. 14 depicts an embodiment in which the padding layer 1404 spans multiple cover panels, shown as cover panels 1402, 1406.
FIG. 15 depicts a cutaway view of an example soccer ball 1500 illustrating an example arrangement of layers. The soccer ball 1500 has a cover 1506, a padding layer 1520, a lining layer 1504, and a core wall 1502. The cover 1506 has an outer surface 1510 defining the outer surface of the soccer ball 1500 and the core wall 1502 has an inner surface 1512 that defines an airtight chamber. Outer surface 1510 can be textured to aid in the aerodynamics of the soccer ball to provide consistent performance. While FIG. 15 depicts the padding layer 1520 positioned between the cover 1506 and the lining layer 1504, the padding layer 1520 can be positioned in a variety of different locations within the soccer ball 1500. In some embodiments, the padding layer 1520 can be the core wall (when the core all forms a bladder) or can be the core itself (when the soccer ball has a solid core). Further, while one padding layer 1520 is illustrated, a plurality of padding layers can be utilized. Each separate padding layer can be manufactured from the same or different type of padding materials. For example, the padding layer positioned closer to the exterior of the soccer ball 1500 may be closed foam to reduce moisture absorption and retention.
As depicted in FIG. 15, each layer can have a thickness, with the thickness of the core wall 1506 shown as T1, the thickness of the padding layer 1520 shown as T2, the thickness of the lining layer 1504 shown as T3, and the thickness of the core wall 1502 shown as T4. In some embodiments, the thickness T1 is in the range of about 1 mm to about 10 mm, the thickness T2 is in the range of about 1 mm to about 50 mm, the thickness T3 is in the range of about 1 mm to about 10 mm, and the thickness T4 is in the range of about 1 mm to about 10 mm. In some embodiments, the thickness of the padding layer (or total thickness of a plurality of padding layers) comprises at least 10% of the overall thickness of the composite layers (e.g., T2/(T1+T2+T3+T4)*100). In some embodiments, the thickness of the padding layer (or total thickness of a plurality of padding layers) comprises at least 25% of the overall thickness of the composite layers. In some embodiments, the thickness of the padding layer (or total thickness of a plurality of padding layers) comprises at least 50% of the overall thickness of the composite layers. In some embodiments, the thickness of the padding layer (or total thickness of a plurality of padding layers) comprises at least 50% of the overall thickness of the composite layers. In some embodiments, the thickness of the padding layer (or total thickness of a plurality of padding layers) comprises at least 75% of the overall thickness of the composite layers. In some embodiments, the thickness of the padding layer comprises at least 90% of the overall thickness of the composite layers.
As mentioned above, in some embodiments, a padding layer of a soccer ball in accordance with the present disclosure can in include structures that define a plurality of deformable voids. FIGS. 16A-16B depict a cutaway view of an example soccer ball 1600 illustrating an example arrangement of layers that includes a layer defining a plurality of deformable voids. The soccer ball 1600 has a cover 1606, a padding layer 1620, a lining layer 1604, and a core wall 1602. The cover 1606 has an outer surface 1610 defining the outer surface of the soccer ball 1600 and the core wall 1602 has an inner surface 1612 that defines a pressurizable airtight chamber. The outer surface 1610 can be textured to aid in the aerodynamics of the soccer ball to provide consistent performance. While FIG. 16 depicts the padding layer 1620 positioned between the cover 1606 and the lining layer 1604, the padding layer 1620 can be positioned in a variety of different locations within the soccer ball 1600. In some embodiments, the padding layer 1620 can be the core wall (when the core all forms a bladder) or can be the core itself (when the soccer ball has a solid core). Further, while one padding layer 1620 is illustrated, a plurality of padding layers can be utilized. Each separate padding layer can be manufactured from the same or different type of padding materials. For example, the padding layer positioned closer to the exterior of the soccer ball 1600 may be closed foam to reduce moisture absorption and retention and the inwardly positioned padding layers can include the structures defining the deformable voids.
The padding layer 1620 is shown to include a webbing 1652 that defines a plurality of deformable voids 1650. In this embodiment, the deformable voids 1650 are positioned between the cover 1606 and the lining layer 1604, but this disclosure is not so limited. In some embodiments, the webbing 1652 may define more than 1 deformable voids per square inch. In some embodiments, the webbing 1652 may define more than 4 deformable voids per square inch. In some embodiments, the webbing 1652 may define more than 8 deformable voids per square inch. In some embodiments, the webbing 1652 may define more than 15 deformable voids per square inch. Further, while the deformable voids 1650 are shown as being generally hemispherically shaped, any suitable shape can be used without departing from the scope of the current disclosure. For instance, in some embodiments, the deformable voids 1650 are spherical and positioned completely internal to the padding layer 1620. In some embodiments, the deformable voids 1650 are cylindrical/tubular and extend either partially or completely through the padding layer 1620. As is to be appreciated, a wide variety of deformable void shapes can be utilized. In any event, the webbing 1652 can provide sufficient structural rigidity to maintain the shape of the deformable voids 1650 while in a relaxed state (shown in FIG. 16A) and allow deformation of the deformable voids 1650 while an external force is applied to the outer surface 1610 of the soccer ball 1600.
As depicted in FIG. 16A, and similar to FIG. 15, each layer can have a thickness, with the thickness of the core wall 1606 shown as T1, the thickness of the padding layer 1620 shown as T2, the thickness of the lining layer 1604 shown as T3, and the thickness of the core wall 1602 shown as T4. In some embodiments, the thickness T1 is in the range of about 1 mm to about 10 mm, the thickness T2 is in the range of about 1 mm to about 50 mm, the thickness T3 is in the range of about 1 mm to about 10 mm, and the thickness T4 is in the range of about 1 mm to about 10 mm. In some embodiments, the thickness of the padding layer (or total thickness of a plurality of padding layers) comprises at least 10% of the overall thickness of the composite layers. In some embodiments, the thickness of the padding layer (or total thickness of a plurality of padding layers) comprises at least 25% of the overall thickness of the composite layers. In some embodiments, the thickness of the padding layer (or total thickness of a plurality of padding layers) comprises at least 50% of the overall thickness of the composite layers. In some embodiments, the thickness of the padding layer (or total thickness of a plurality of padding layers) comprises at least 50% of the overall thickness of the composite layers. In some embodiments, the thickness of the padding layer (or total thickness of a plurality of padding layers) comprises at least 75% of the overall thickness of the composite layers. In some embodiments, the thickness of the padding layer comprises at least 90% of the overall thickness of the composite layers.
FIG. 16B depicts the soccer ball 1600 with a force being applied to the outer surface 1610, as indicated by arrow 1660. Such force can be from a player's head, for instance. The thickness of some of the layers of the soccer ball 1660 do not change, or do not substantially change, under the application force. The thickness of the padding layer 1620, however, reduces to a thickness of T2′ at the area of the soccer ball 1600 proximate to the application of force 1660. The thickness of the padding payer 1620 can be changed from T2 (FIG. 16A) to T2′ (FIG. 16B) through the deformation of the deformable voids 1650 as the webbing 1652 contorts based on the force. In some embodiments, the thickness T2′ proximate to the area of the soccer ball 1600 to which the force is applied can be less than about 80% of the thickness of T2. In some embodiments, the thickness T2′ proximate to the area of the soccer ball 1600 to which the force is applied can be less than about 60% of the thickness of T2. In some embodiments, the thickness T2′ proximate to the area of the soccer ball 1600 to which the force is applied can be less than about 40% of the thickness of T2. In some embodiments, the thickness T2′ proximate to the area of the soccer ball 1600 to which the force is applied can be less than about 25% of the thickness of T2. The thickness of T2′ can also depend on the level of force applied to the outer surface 1610. Upon the removal of the force 1660, the shape of the deformable voids 1650 can return to the shape illustrated in FIG. 16A.
While the padding layer 1620 depicts one example arrangement of deformable voids 1650 defined by the webbing 1620, a variety of different types of padding layers can be utilized, some non-limiting examples of which are depicted in FIGS. 17-18. Referring first to FIG. 17, a padding layer 1720, shown in a planar form for clarity, depicts one example type of padding layer that can be incorporated in a soccer ball, or other type of ball. The padding layer 1720 has a webbing 1752 that structurally defines a plurality of deformable voids 1750. As shown, the deformable voids 1750 vary in size, shape, and depth. The thickness T2 of the padding layer 1720 can be in the range of about 1 mm to about 50 mm. Referring now to FIG. 18, a padding layer 1820, which is also shown in a planar form for clarity, depicts another example type of padding layer that can be incorporated in a soccer ball, or other type of sports ball. The padding layer 1820 has a webbing 1852 that structurally defines a plurality of deformable voids 1850. As shown, the deformable voids 1850 are generally uniform in shape, having a tubular structure. Similar to the embodiments described above, the padding layers 1720 and 1820 can each comprise a plurality of padding panels.
In various embodiments disclosed herein, a single component may be replaced by multiple components and multiple components may be replaced by a single component to perform a given function or functions. Except where such substitution would not be operative, such substitution is within the intended scope of the embodiments. While various embodiments have been described herein, it should be apparent that various modifications, alterations, and adaptations to those embodiments may occur to persons skilled in the art with attainment of at least some of the advantages. The disclosed embodiments are therefore intended to include all such modifications, alterations, and adaptations without departing from the scope of the embodiments as set forth herein.
