Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates generally to athletic protector cups, and more particularly to an athletic protector cup having a flexible resilient portion molded thereto for providing improved protection and comfort to the wearer.




2. Description of the Prior Art




Devices for the protection of the male groin region are extensively utilized in athletics. In athletic competition, particularly body contact sports such as football, baseball, hockey, soccer and the like, protective devices are worn by the players to avoid injury due to inadvertent blows to the groin area. The most common protective device includes a cup supported by a jockstrap. Protector cups of this character are usually formed from a plastic material, such as polypropylene or polyethylene, which is sufficiently rigid to retain its shape even when struck a relatively severe blow.




Historically, protector cups have been provided with a resilient padding about their periphery both for the comfort of the wearer and, in some measure, to absorb the impact of a blow to the protector cup. The resilient padding is usually formed from a soft, flexible foam-like material, such as foam rubber or polyurethane foam, and is usually provided in the form of a limited elongated strip manually attached to the peripheral edge of the cup with the aid of an adhesive. Such conventional padded cups suffer a number of disadvantages and limitations. For instance, the pad attachment procedure is both time consuming and costly, and the bond between the padding and the protector cup is often deficient. Separation of the padding and the protector cup typically occurs during repeated use of the protector when the padding is peeling away from the restricted area of attachment to the cup. Furthermore, such known structures, in view of the restricted extent of the padding, offer only limited impact absorption protection. Consequently, upon impact a significant portion of the blow is transferred to the body of the wearer. Examples of athletic protector cups incorporating such conventional peripheral padding are provided in U.S. Pat. Nos. 2,283,684; 3,782,375; 4,453,541 and 4,134,400.




U.S. Pat. No. 4,257,414 discloses an athletic protector cup having a resilient peripheral binding molded to a peripheral cup flange. The molded binding structure disclosed in the this patent provides some benefits vis-a-vis the aforementioned conventional padded cup structures. For instance, molding provides a more efficient and cost-effective means of attachment than a conventional adhesive foam strip. Furthermore, the disclosed binding is contoured to have a relatively thick outwardly-extending body portion for providing improved comfort to the wearer and improved impact absorption. However, the athletic cup structure disclosed in this patent has some significant drawbacks and limitations. For instance, to prevent separation of the molded binding from the cup over time, the cup must be manufactured having a series of perforations along the flange. In other words, to achieve adequate attachment of the binding to the cup flange, the binding material is required to flow through relatively small perforations during assembly. This is necessary to provide interlocks integrally connecting the portions of the binding lying on opposite sides of the flange. Furthermore, the relative increase in impact resistance provided by the disclosed flange geometry leaves significant room for improvement. This is because only a limited area of hard-shell is covered by soft binding. Additionally, the disclosed binding surface geometry of the outwardly extending body portion includes sharp edges which could result in chafing during frictional contact with the wearer's body.




Accordingly, there is an established need for an athletic protector cup overcoming the aforementioned drawbacks and limitations of the prior art.




SUMMARY OF THE INVENTION




It is an object of the present invention to provide an athletic protector cup including a rigid plastic base having a resilient body extending over a substantial portion or entire outer surface thereof for dampening the impact of a blow to the outer surface of the cup.




It is another object of the present invention to provide an athletic protector cup having a peripheral flexible flange for further dampening the impact of a blow to the outer surface of the cup.




It is a further object of the present invention to provide an athletic protector cup having a peripheral flexible flange geometry designed to collapse under forces applied by the cup to the wearer during various body movements, or under the force of a sudden impact, in such a manner as to create a cushioning barrier between the rigid plastic base and the wearer's body.




It is still a further object of the present invention to provide an athletic protector cup having a flexible flange incorporating a surface geometry for providing improved comfort to the wearer by minimizing frictional contact with the wearer's skin.




It is yet a further object of the present invention to provide an athletic protector cup incorporating a flexible resilient body portion molded to a rigid base in such manner as to minimize the risk of separation of the molded portion from the rigid base.




One aspect of the invention provides an athletic protector including a rigid cup-shaped member having interior and exterior surfaces defined along their peripheries by an edge having an upper segment and opposite side segments. A flexible resilient body covers a substantial portion of the exterior surface and extends around at least a portion of the peripheral edge. The resilient body is fixedly attached over at least a portion of the exterior surface of the base member.




As to another aspect of the invention, the flexible resilient body is molded over substantially the entire exterior surface of the rigid cup base member and around the length of peripheral edge. The flexible resilient body can also be molded over substantially the entire interior and exterior surface of the rigid cup-shaped base member.




A further embodiment of the invention provides an athletic protector wherein the upper segment of the peripheral edge terminates at a first integral lip and the lower segment of the peripheral edge terminates at a second integral lip. The flexible resilient body envelopes the first and second integral lips. The opposite side segments of the rigid cup peripheral edge have an inwardly stepped surface forming an exterior leading edge. The flexible resilient body is molded around the leading edge.




Still another aspect of the invention provides the flexible resilient body having a cup-shaped portion overlying substantially the entire exterior surface of the rigid cup-shaped base member. The cup-shaped portion of the flexible-resilient body has a thickened flange portion extending around substantially its entire periphery. The thickened flanges portion terminates at a rounded end having generally crescent-shaped cross-section geometry. The rounded end has a convex outer surface and a concave inner surface. Upon application of a force to an exterior surface of the athletic protector, the thickened flange portion collapses inwardly in such a manner as to form a cushion barrier between the rigid peripheral edge of the base member and the body of the wearer.




Still further aspect of the invention provides the athletic protector in which the resilient flexible body is made of an elastomer and the resilient flexible body is injection molded to the rigid cup-shaped base.




These and other objects and aspects of the invention are achieved by the athletic protector cup which is described hereinbelow.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS




The athletic protector cup of the present invention comprises a rigid unified structure and a resilient structure. When the athletic protector cup is fully constructed these elements are integrated to form a single cup structure. However, for the purpose of clarity, in portions of the following description and referenced drawing figures the respective structures are described and illustrated isolated from each other.




Referring initially to

FIGS. 1-6

, wherein the rigid portion of the cup structure, shown generally at


10


, is illustrated in detail. The cup-shaped rigid base member


10


is contoured to cover and protect the genitals of a wearer and can be formed from numerous rigid plastic materials, such as polypropylene or high-density polyethylene. The rigid cup base has arcuate exterior and interior surfaces,


16


and


18


, respectively. Furthermore, the rigid cup base has upper and lower ends, shown generally at


14


and


12


, respectively. Although the exterior and interior surfaces can be smooth, in the embodiment of the invention illustrated in

FIGS. 1-6

, the upper


14


and lower


12


cup ends, have respective integral lip portions,


22


and


20


, extending outwardly therefrom. The lips are thickest in cross section at their respective midpoints, each having an inwardly tapering smooth surface curving along the body perimeter in a direction away from its midpoint.




Exterior and interior cup surfaces,


16


and


18


, are joined at a peripheral edge shown generally at


24


. As best illustrated in

FIG. 5

, peripheral edge


24


actually has a stepped-shaped configuration, forming an inner edge


28


and an outer leading edge


29


. Accordingly, in this embodiment of the invention, the exterior cup surface


16


is peripherally bounded at its upper and lower ends by integral lip portions


20


and


22


, respectively, and at its sides by leading edge


29


. Similarly, interior cup surface


18


is peripherally bounded by integral lip portions,


20


and


22


, and inner edge


28


. Preferably, rigid base


10


is further provided with a plurality of apertures


26


for ventilation purposes.




As will be further described herein below, the integral lip portions,


20


and


22


, and leading edge


29


provide means for securely integrating the rigid base and resilient body portions of the athletic cup protector of the present invention.




Referring now to

FIGS. 7-10

, the structure of resilient body


40


will now be described in more detail. Resilient body


40


is preferably constructed from a flexible and resilient elastomer material having a chemical structure compatible with the rigid base member to ensure adequate adhesion thereto. In particular, adhesion at the interfaces should be sufficient to minimize interfacial separation over time under normal cup usage conditions. As will be apparent to those skilled in the art of molding technology, myriad elastomer materials are commercially available for use with the present invention, including, for example, rubber and polyurethane.




Resilient body


40


extends between an upper end


44


and lower end


42


and is comprised of a thin cap-shaped portion, shown generally at


50


, and a thickened flange portion, shown generally at


60


. As viewed in cross-section, thickened flange portion


60


includes a generally rectangular-shaped portion


62


having a slight lengthwise curve defined by the contour of surface


46


, and extends downwardly into an integral crescent-shaped portion


68


. The crescent-shaped portion


68


of thickened flange


60


has a cross-sectional area bounded by convex outer surface


61


and concave inner surface


63


.




The smooth rounded convex outer surface


61


provides a comfortable, low friction, contact region between the flange and the body of the wearer. This feature of the present invention provides the advantage, vis-a-vis prior art flange designs. This is because this feature reduces body irritation resulting from repeated rubbing of the flange surface against the wearer's body during various body movements including, for example, the repeated bending of a catcher during a baseball game.




Concave inner surface


63


defines an integral channel


70


which extends around the lower interior of thickened flange


60


. Thin cap-shaped portion


50


is bounded by upper surface


46


, lower surface


48


, and a periphery defined by recessed surface


66


of thickened flange portion


60


. As will be described in more detail hereinbelow, during the assembly operation surfaces


64


,


65


and


66


of flange portion


62


mate with rigid cup surfaces


28


,


27


and


29


, respectively. In other words, the surfaces


64


,


65


and


66


defining the upper bounds of thickened section


62


correspond to the curved sides


24


of the rigid cup


10


. Accordingly, the cross-sectional area of portion


62


varies around the periphery of molded body


40


. This variation is best illustrated in

FIG. 10

, in which thickened flange surface


66


is represented in phantom.




Resilient body


40


can be formed with multiple ventilation apertures


45


, so that in the assembled condition of the invention these apertures coincide with the apertures


26


of the rigid cup


10


.




Referring now to

FIGS. 11-13

and


15


, the athletic protector cup of the present invention is illustrated in a fully-constructed, state. It will be apparent to those skilled in the art of athletic protector cups that many conventional means of permanent connection between rigid cup-shaped base member and the flexible resilient body can be utilized. However, the connection between these elements by molding is preferred. It will also be apparent to those skilled in the art of molding that various molding methods incorporating a variety of molding parameters could be employed to achieve the athletic protector cup structure of the present invention. In the preferred embodiment of the present invention, resilient body


40


and rigid cup base


10


are chemically married using an injection molding process. Injection molding of thermoplastic elastomers (TPE) compounds onto engineering thermoplastic resins is well known and is not further described. Specific information relating to TPE injection molding can be found throughout the scientific literature. For example, an article specifically relating to TPE overmolding can be found in the Journal of Injection Molding Technology (March 2000, Vol. 4, No. 1).




Preferably, outer surface


16


of rigid cup


10


is chemically bonded over substantially its entire surface area to interior surface


48


of molded body


40


. As best illustrated in

FIG. 12

, surfaces


27


,


28


and


29


of rigid cup


10


are preferably molded to corresponding surfaces


66


,


65


and


64


of molded body


10


, thereby forming an interlocking structure for enhancing the stability of rigid cup


10


within molded body


40


. As best illustrated in

FIG. 13

, in this embodiment of the invention, portion


68


of thickened flange


60


completely envelops the integral upper and lower lips


22


and


20


of rigid cup base


10


. In a manner similar to the interlocking structure described above, this mating structure further reduces the potential for interfacial separation by maintaining rigid cup


10


and resilient body


40


in a fixed position relative to each other.




The overmolded resilient body structure of the present invention provides numerous significant advantages over the prior art flange structures. For instance, in contrast to known athletic protector cups which provide a resilient body restricted to a peripheral portion of the cup, the resilient elastomer structure of the present invention is molded over the outer surface


16


of the rigid cup to provide an impact resistant barrier. In this manner, the magnitude of a blow to the exterior surface of the protector cup is significantly reduced, or dampened, before being transferred to the rigid plastic inner cup layer. As a result of this improved dampening, the athletic protector cup of the present invention can be constructed using a thinner rigid cup base


10


, providing a corresponding weight reduction of approximately 20-30% compared to conventional athletic protector cups.




Further advantages result from the self-collapsing design of the integral flange structure. Referring now to

FIGS. 16



a


and


16




b


, under the impact of an external force, F, upon outer surface


46


, flexible flange portion


62


deflects, or folds, inwardly. At least two significant advantages accrue from this self-collapsing design. First, the inwardly folding flange portion


62


forms a barrier between the rigid perimeter side edges


24


of inner cup


10


and the wearer's body to provide enhanced comfort during the application of a force, F, on the cup. Such force may result from a blow to the cup. Alternatively, such force may result from various bodily movements, such as bending, while wearing the cup. As a consequence of the significant improvements in comfort to the wearer, the athletic protector cup of the present invention lends itself to use by certain athletes, such as soccer players, who commonly play without a protector cup to avoid the discomfort associated with existing cup structures. Second, the inwardly collapsing structure provides enhanced impact resistance in situations where the force results from a blow to the cup, further minimizing the transmission of the force to the wearer's body.




As best illustrated in

FIG. 10

, in the central region of the athletic protector (commonly engaging the body of the wearer) the rigid peripheral edges of the cup (shown in phantom) are remote from the outer surface


61


of the resilient body portion. Thus, in the assembly of the invention, a substantial portion of the rigid plastic is substituted by a soft plastic of the resilient body, further enhancing comfort to the wearer.




The smooth rounded convex outer surface


61


provides a comfortable, low friction, contact region between the flange and the body of the wearer. Concave inner surface


63


defines an integral channel


70


which extends completely around the lower interior of thickened flange


60


.




The resilient body


40


and rigid cup base


10


are fixedly connected. Outer surface


16


of rigid cup


10


is bonded over substantially its entire surface area to interior surface


48


of impact resistant body


40


. The surfaces


27


,


28


and


29


of rigid cup


10


are attached to corresponding surfaces


65


,


64


and


66


of rigid cup


10


, thereby forming an interlocking structure. This enables the invention to enhance the stability of rigid cup


10


within body


40


.




The flexible end portion


68


of the flexible resilient body envelops the integral upper and lower ends of rigid cup base


10


. This mating structure further reduces the potential for interfacial separation by maintaining rigid cup


10


and resilient body


40


in a fixed position relative to each other.




Under the impact of an external force, outer surface of the flexible resilient body


46


, its flexible end flange portion


62


deflects, or folds, inwardly, thereby forming a barrier between the rigid perimeter side edges of cup shaped base member


10


and the wearer's body. This provides enhanced comfort during the application of a force, on the cup. Furthermore, the inwardly collapsing structure enhances impact resistance of the structure when the force of a blow is applied to the cup.




While the preferred embodiments of the invention have been illustrated and described, it will be clear that the invention is not limited to these embodiments only. Numerous modifications, changes, variations, substitutions and equivalents will be apparent to those skilled in the art without departing from the spirit and scope of the present invention as described in the claims. For example, resilient body


40


can be further extended over the entire inner surface


18


of rigid cup-shaped base member


10


, thereby completely encapsulating the hard cup. The rigid cup-shaped base member can be formed having smooth outer surface and inner surface


18


, without lip portions


20


and


22


, etc.,.
