1. Field of the Invention
Apparatuses and methods consistent with the present invention generally relate to a protective cup and a method of manufacturing the protective cup. The protective cup may be used, for example, in athletic and/or other activities requiring protection for the lower abdominal and/or genital area of men, women, boys, and/or girls.
2. Description of the Related Art
Protective cups have been used for many years by athletes. Traditionally, players in baseball, boxing, football, hockey, lacrosse, and rugby have used such cups to protect themselves from injury resulting from sporting contact with other players (i.e., checking or tackling) and other types of external impact (i.e., getting hit by a pitch or shot). More recently, protective cups have become important in other sports such as martial arts, mountain biking, motocross, snow skiing, waterskiing, and the like. Similarly, in fields such as professional security or the military, where interaction with protesters, suspected criminals, or terrorists may involve violent physical contact, a protective cup may make the difference between a successful and an unsuccessful interaction.
Traditional protective cups have a number of deficiencies. First, they are often bulky, restricting movement of the wearer. Second, this bulkiness often results in their being heavy and, thus, tiring to wear for an extended period. Third, they often are rigid, again restricting movement of the wearer and contributing to the wearer's discomfort. Fourth, they often have poor ventilation, exacerbating the wearer's discomfort. And fifth, some of these protective cups are fairly complex, contributing to higher manufacturing costs and sales price, as well as increased maintenance problems and shortened product life.
Therefore, there is a need for a protective cup that is simple, lightweight, compact, flexible, more comfortable, and has improved ventilation.
Illustrative, non-limiting embodiments of the present invention overcome the above disadvantages and other disadvantages not described above. However, the present invention is not required to overcome the disadvantages described above, and an illustrative, non-limiting embodiment of the present invention may not overcome any of the problems described above.
In one aspect of the present invention, a protective cup comprises a cage member and a peripheral lip. The cage member comprises an upper portion, a lower portion, and side portions. The cage member further comprises one or more substantially rigid materials. The upper portion comprises a plurality of slots, wherein each slot is oriented so that a direction defined by a largest dimension of a respective slot extends toward the lower portion. The peripheral lip is operatively connected to the upper, lower, and side portions.
In another aspect of the present invention, a protective cup comprises a cage member, a peripheral lip, and linking portions. The cage member comprises an upper portion, a lower portion, and side portions. The peripheral lip is operatively connected to the upper and lower portions and is distanced from the cage member at openings between the peripheral lip and the side portions. The linking portions operatively connect the peripheral lip to the side portions to fill the openings or one or more parts of the openings.
In yet another aspect of the present invention, a protective cup comprises a cage member, a peripheral lip, and linking portions. The cage member comprises an upper portion, a lower portion, and side portions. The upper portion comprises a plurality of slots. The peripheral lip is operatively connected to the upper and lower portions and is distanced from the cage member at openings between the peripheral lip and the side portions. The linking portions operatively connect the peripheral lip to the side portions to fill one or more parts of the openings.
In yet a further aspect of the invention, a method of manufacturing the protective cups is disclosed.
Aspects of the present invention will become more apparent by describing in detail illustrative, non-limiting embodiments of the present invention with reference to the accompanying drawings, in which:
With reference to
For a proper fit, the size of protective cup 100 usually varies with the size of the user.
As used herein, the term “about” means exactly a given value or the given value ±10%.
Cage member 102 comprises upper portion 110, lower portion 112, and side portions 114 and 116. Although protective cup 100 may have any desired shape, it may, for example, comprise a concave inner surface 122 and a convex outer surface 124 as shown, for example, in
Given concave inner surface 122, the center of gravity of upper portion 110 does not lie within upper portion 110. Similarly, the center of gravity of lower portion 112 does not lie within lower portion 112. Nor does the center of gravity of peripheral lip 104 lie within peripheral lip 104. As a result, the centers of gravity of upper portion 110, lower portion 112, and peripheral lip 104 all lie on the concave-inner-surface side of protective cup 100. When these three centers of gravity are non-colinear, they determine a unique plane.
Cage member 102 may further comprise an edge 118 that may extend, for example, part way or all the way around cage member 102. The cross-sectional shape of edge 118 may facilitate operatively connecting peripheral lip 104 to upper portion 110, lower portion 112, and/or side portions 114 and/or 116. Also, edge 118 may improve user safety and/or comfort by comprising, for example, one or more curved, rounded, or other cross-sections as shown, for example, in
The shape of cage member 102 may be substantially symmetrical to the unique plane determined by the three centers of gravity. In addition, the shape of protective cup 100 may be substantially symmetrical to that same plane. As used herein, the term “substantially symmetrical” means symmetrical, with possible minor variations due to manufacturing tolerances and/or indicia such as manufacturing information, product identifiers, trademarks, and/or logos.
Upper portion 110 comprises a plurality of slots 120. As used in the present application, the term “slot” means an aperture comprising a non-circular shape in which a first dimension of the aperture, measured in a first direction, is at least two times larger than a second dimension of the aperture, measured in a second direction, where the second direction is approximately perpendicular to the first direction. Thus, the term “slot” would include, for example, the first dimension being at least three, four, five, six, seven, eight, nine, ten, or more times larger than the second dimension. Upper portion 110 may comprise, for example, two, three, four, five, six, seven, eight, nine, ten, or more slots 120. In one embodiment, upper portion 110 comprises three slots.
Slots 120 may be open and/or closed. That is, the associated aperture may extend into upper portion 110 from a border of upper portion 110 so that the slot is open over a portion of its periphery, or the associated aperture may lie entirely within upper portion 110 so that the slot is closed over its entire periphery. By covering the open portion of its periphery, peripheral lip 104 may effectively close otherwise open slot 120.
Slots 120 can reduce the weight, increase the flexibility, and/or improve the ventilation of cage member 102. As a result, slots 120 also can reduce the weight, increase the flexibility, improve the ventilation, and/or enhance the comfort of protective cup 100.
Slots 120 may comprise many different shapes. Slots 120 may comprise, for example, one or more shapes that approximate one or more triangles, quadrilaterals, pentagons, hexagons, and/or other polygons. Such polygons may or may not be regular polygons. However, the shape/shapes of slots 120 does/do not need to approximate one or more polygons. So, for example, slots 120 may comprise one or more shapes that approximate one or more crescents, hearts, ellipses (with sufficient eccentricity to meet the definition of the term “slot”), and/or arc sections of a circle.
Slots 120 also may comprise one or more shapes that approximate one or more letters such as, for example, “I-shaped”, “L-shaped”, “S-shaped”, “T-shaped”, “V-shaped”, and/or “X-shaped”. Additionally, slots 120 may comprise, for example, one or more shapes that approximate one or more trademarks, logos, and/or slogans (or outlines of the trademarks, logos, and/or slogans). Thus, slots 120 could be used to spell, for example, the name of the manufacturer of protective cup 100, a sponsor, a sport, a team, a player, a competition, and/or incorporate other potential advertising and/or marketing techniques.
At least one of slots 120 may comprise, for example, a generally rectangular shape. As used herein, the term “generally rectangular” means resembling a regular or non-regular four-sided polygon, in which: one or more of the sides may be curved; opposite sides may be parallel, substantially parallel, or generally parallel; one or more of the vertices may be rounded; and/or one or more of the vertices may form an angle greater than or equal to about 60° and less than or equal to about 120°. As used herein, the term “substantially parallel” means exactly parallel or parallel within ±10 degrees. As used herein, the term “generally parallel” means exactly parallel or parallel within ±20 degrees.
If there are two slots 120, then one slot 120 may comprise a shape that is the same as or different from the other slot 120. If there are more than two slots 120, then each slot 120 may comprise a shape that is the same as or different from any or all of the other slots 120.
Slots 120 may be oriented so that a direction T1 defined by a largest dimension of one of slots 120 extends toward lower portion 112 and/or side portions 114 and/or 116. In
Slots 120 may be oriented so that the largest dimension of a first slot 120 is substantially parallel to the largest dimension of at least one other slot 120. Further, slots 120 may be oriented so that the largest dimension of each slot 120 is generally parallel to the unique plane determined by the three centers of gravity. Yet further, slots 120 may be oriented so that two or more of slots 120 are parallel, substantially parallel, or generally parallel to each other.
Also, slots 120 may have other orientations. For example, slots 120 can be oriented in a fan shape, closer together near the middle of cage member 102, or a reverse fan shape, farther apart near the middle of cage member 102.
In one embodiment, protective cup 100 comprises three generally rectangular slots 120 oriented so that all three slots 120 are substantially parallel to each other and with each slot 120 comprising a length L1 of about 3 inches and a width W1 of about ¼ inch.
Lower portion 112 may be solid, substantially solid, or generally solid. As used herein, the term “solid” means a surface with no apertures, the term “substantially solid” means a surface with no apertures or with no more than 20% of the surface penetrated by apertures, and the term “generally solid” means a surface with no apertures or with no more than 40% of the surface penetrated by apertures.
Lower portion 112 may comprise, for example, one or more apertures of any desired shape. Such apertures can reduce the weight, increase the flexibility, and/or improve the ventilation of cage member 102. As a result, the apertures also can reduce the weight, increase the flexibility, improve the ventilation, and/or enhance the comfort of protective cup 100.
Side portions 114 and 116 may be solid, substantially solid, or generally solid. Side portions 114 and 116 may comprise, for example, one or more apertures of any desired shape. Such apertures can reduce the weight, increase the flexibility, and/or improve the ventilation of cage member 102. As a result, the apertures also can reduce the weight, increase the flexibility, improve the ventilation, and/or enhance the comfort of protective cup 100. Side portion 114 may be symmetric to side portion 116.
Although cage member 102 may comprise any desired shape, it may, for example, comprise a concave inner surface 122 and a convex outer surface 124 as shown, for example, in
Cage member 102 comprises one or more rigid or substantially rigid materials so that cage member 102 retains its shape, to a large extent, when impacted. As used herein, the term “rigid” means: for rubbers, plastics, and other non-metallic materials that are subjected to hardness testing according to ASTM D-2240, a Shore D hardness of at least 75 according to ASTM D-2240, and for other materials, a hardness value according to a standardized method providing protection for the user equivalent to the Shore D hardness discussed in this sentence. As used herein, the term “substantially rigid” means: for rubbers, plastics, and other non-metallic materials that are subjected to hardness testing according to ASTM D-2240, a Shore D hardness of at least 60 according to ASTM D-2240, and for other materials, a hardness value according to a standardized method providing protection for the user equivalent to the Shore D hardness discussed in this sentence. Thus, the term “substantially rigid” would include, for example, rubbers, plastics, and other non-metallic materials that are subjected to hardness testing according to ASTM D-2240, a Shore D hardness of at least 65 according to ASTM D-2240.
Such rigid or substantially rigid materials may comprise, for example, polymer materials such as polypropylene, polyethylene, polybutylene terephthalate, acrylonitrile butadiene styrene (“ABS”), polycarbonate (“PC”), and ABS/PC alloys. Desired properties of the rigid or substantially rigid materials include, for example, one or more of hardness, toughness, low density (i.e., light weight), and inertness (to minimize skin irritations, rashes, etc.). As a result, the one or more rigid or substantially rigid materials could comprise, for example, at least one of: metals; natural or synthetic rubber compounds with reinforcing fibers (such as Kevlar® pulp); or Kevlar®. The one or more rigid or substantially rigid materials may incorporate advances from the nanotechnology field. In one embodiment, cage member 102 comprises one substantially rigid material, Thermoplastic Polyurethane (“TPU”).
If desired, any or each of upper portion 110, lower portion 112, side portions 114 and/or 116, and edge 118 (if present) may be formed of different substantially rigid materials.
Although peripheral lip 104 may have any desired shape, it may, for example, comprise a generally tubular or cylindrical form. This form may be substantially flattened along a surface intended to directly or indirectly contact the body of the user. Additionally, the form may include a slit over at least a portion of peripheral lip 104 to facilitate operatively connecting it to upper portion 110, lower portion 112, and side portions 114 and 116. Also, peripheral lip 104 may directly contact at least part of upper portion 110, at least part of lower portion 112, and/or at least part of side portions 114 and/or 116.
Peripheral lip 104 comprises at least one resilient material that provides at least some cushioning effect when protective cup 100 is impacted. Such materials may include, for example, natural or synthetic rubber, a natural or synthetic rubber compound, polyurethane, and ethylene vinyl acetate. Desired properties of the resilient material include, for example, one or more of softness, flexibility, resilience, low density (i.e., light weight), and inertness (to minimize skin irritations, rashes, etc.). In one embodiment, the resilient material is TPU.
Cage member 102 and peripheral lip 104 may be manufactured using any suitable process known to one of skill in the art, such as, for example, extrusion, vacuum forming, or injection molding. The process may also comprise, for example, the use of adhesives or chemical bonding. Regarding cage member 102, upper portion 110 may be manufactured separately from or together with one or more of lower portion 112, side portions 114 and/or 116, and edge 118 (if present). Also, cage member 102 may be manufactured separately from or together with peripheral lip 104. Additionally, any or all of upper portion 110, lower portion 112, side portions 114 and/or 116, and edge 118 (if present) may be manufactured separately from or together with peripheral lip 104.
In one embodiment, cage member 102 (with edge 118, if present) is manufactured as a single unit by injection molding, with peripheral lip 104 added by injection molding.
