The present disclosure relates to protective coverings. More particularly, the present disclosure relates to athletic guards comprising multiple materials.
Participants of athletic or other physical activities often wear one or more protective coverings to reduce the intensity of any resultant impacts to the body that may occur. Contact sports such as football and hockey are especially likely to cause high impacts to the body and therefore players often wear athletic guards to reduce the risk of injury. Examples of protective coverings include hand pads, elbow pads, thigh guards, shin guards, and knee pads. Typically a variety of materials with varying properties can be employed to provide a more robust protective covering. However, due to the strenuous nature of physical activities, the materials that make up the protective covering can unintentionally separate, thereby compromising the integrity of the protective covering.
This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential elements of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter. The present invention is defined by the claims.
At a high level, aspects herein relate to protective coverings, such as athletic guards. A protective covering may comprise a central protective plate portion formed from, for instance, a rigid material that provides structural support and shields a wearer of the protective covering from impact. As used throughout this disclosure, the term “rigidity” refers to the extent to which a material resists deformation in response to an applied force. The rigidity of a material can be established by American Society for Testing and Materials (ASTM) standard testing methods, by way of example.
The protective covering may also comprise a terminal edge portion that at least partially encircles the plate portion. The edge portion can be formed from, for instance, a pliable material that absorbs impacts to the protective covering while providing a comfortable interface between the wearer and the protective covering. As used throughout this disclosure, “pliability” refers to the extent to which a material yields to deformation in response to an applied force.
The pliable material of the edge portion is less rigid (i.e., has lower rigidity) than the rigid material of the plate portion. In turn, the rigid material of the plate portion is less pliable (i.e., has lower pliability) than the pliable material of the edge portion. Including materials comprising at least the pliable and rigid materials allows for a robust protective covering.
In an exemplary aspect, a coupling region may be interposed between the terminal edge portion and the central protective plate portion. The coupling region can transition from the pliable material of the terminal edge portion to the rigid material of the central protective plate portion, where the coupling region extends from a first edge to a second edge. The first edge has a higher concentration of the pliable material than the rigid material, and the second edge has a higher concentration of the rigid material than the pliable material. Furthermore, a first surface (e.g., a top surface) of the coupling region has a higher concentration of the pliable material than the rigid material, and a second surface (e.g., a bottom surface opposing the top surface) of the coupling region has a higher concentration of the rigid material than the pliable material. The coupling region can facilitate a strong bond between the pliable and rigid materials, that respectively make up the edge portion and the plate portion, which is resistant to the materials unintentionally separating.
In certain aspects, the edge portion may comprise a lip that extends around the periphery thereof. The lip may form a stitch groove that can enhance the resilience of stitching situated therein. The edge portion may also comprise a rounded terminal that flares away from an individual in an as-worn position. Use of the rounded terminal may help to alleviate pressure points which may otherwise form at areas where the edge portion engages the individual. The lip and the rounded terminal may be formed from a flared lip that may extend around the periphery of the edge portion. The flared lip can be employed to effectively form the lip and the rounded terminal.
In some aspects, the protective plate has a curved bottom portion to conform to a portion of an individual being protected. The protective plate may have at least one convex extent and at least one concave extent along a cross section that is perpendicular to a top surface and/or bottom surface thereof. Such a configuration can enhance the conformity of the protective plate as well as the bending stiffness of the protective covering.
Examples are described in detail below with reference to the attached drawing figures, wherein:
Aspects herein relate to a protective covering, such as an athletic guard. The protective covering may comprise a plate portion formed from, for instance, a rigid material that provides structural support and shields a wearer of the protective covering from impact. The protective covering may also comprise an edge portion that at least partially encircles the plate portion. The edge portion can be formed from, for instance, a pliable material that absorbs impacts to the protective covering while providing a comfortable interface between the wearer and the protective covering that reduces bruising or compressive-type injuries.
The pliable material of the edge portion is less rigid (i.e. has lower rigidity) than the rigid material of the plate portion. In turn, the rigid material of the plate portion is less pliable (i.e. as lower pliability) than the pliable material of the edge portion. Including materials comprising at least the pliable and rigid materials allows for a robust protective covering.

The protective plate may have at least one convex extent and at least one concave extent along a cross section that is perpendicular to a top surface and/or bottom surface thereof. Such a configuration can enhance the conformity of the protective plate as well as the bending stiffness of the protective covering.
Protective coverings as contemplated herein can have general configurations suitable for various activities, and for protecting various portions of an individual. The features or aspects included in a particular protective covering as well as the form and composition of those features can vary from specific implementations shown in order to comply with these and other considerations. Thus, while thigh guards are depicted for illustrative purposes, concepts described herein may be applied to a variety of other types of protective coverings, including other types of athletic guards, such as shin guards, leg guards, head guards, arm guards, etc.
In the implementation shown in
Apparel 104 has the general configuration of pants-type apparel, which includes any of a plurality of articles of apparel that cover a portion of a pelvic area of individual 100 and may extend over legs of individual 100. Although apparel 104 is depicted as being a pair of shorts, exemplary aspects described herein also apply to other pants-type apparel, including pants, briefs, jeans, and underwear. Also, the exemplary aspects described herein apply to shirt-type apparel, which cover a portion of a torso area of individual 100 and can extend over arms of individual 100. Examples of shirt-type apparel include long-sleeved shirts, short-sleeved shirts, tank tops, undershirts, jackets, and coats. A shirt-type appeal may be suitable where one or more protective coverings are arm guards, elbow pads, stomach guards, back guards, shoulder pads, and the like.
The exemplary aspects described herein also apply to combinations of shirt-type apparel and pants-type apparel, including bodysuits, leotards, unitards, and wetsuits. Furthermore, the apparel can have configurations that cover other areas of individual 100, such as hats, helmets, gloves, socks, and footwear, for example. Apparel 104 can be worn in combination with other articles of apparel (e.g., under or over other articles of apparel). Furthermore, apparel 104 can be worn in combination with other pieces of equipment (e.g., athletic or protective equipment). It should be appreciated that the manner in which apparel 104 is configured and is worn by individual 100 can vary significantly. Apparel 104 corresponds to one effective means for securing a protective covering to individual 100; however, apparel 104 is not required.
By securing protective coverings 102a and 102b to individual 100, protective coverings 102a and 102b can cover underlying regions, areas, or portions of individual 100 for protection thereof. In particular, protective coverings 102a and 102b can distribute or attenuate impact forces to individual 100 in those regions, thereby imparting protection to individual 100.
Referring now to
As shown in
Protective plate portion 212 comprises rigid material and can be referred to as a rigid protective plate portion. In some aspects, an entirety of protective plate portion 212 can be formed from the rigid material. Edge portion 210 comprises pliable material and can be referred to as a pliable edge portion. In some aspects, an entirety of edge portion 210 can be formed from the pliable material.
The pliable material of edge portion 210 is of lower rigidity than the rigid material of protective plate portion 212. The lower rigidity can be established by ASTM standard testing methods, by way of example. The pliable material and rigid material can be any of various combinations of polymers. Exemplary pliable material includes polymers, such as phenylene oxide (PPE), thermoplastic polyurethane (TPU), polypropylene, and acrylonitrile butadiene styrene (ABS) TPU. Exemplary rigid materials include semi-rigid flexible polymers, such as a polycarbonate/acrylonitrile-butadiene-styrene (PCABS) blend, carbon fiber, ABS, polystyrene, polypropylene, and nylon. Exemplary hardness can range from approximately Soft Shore 40 for the pliable material to approximately Soft Shore 100 for the rigid material.
Employing at least the rigid and pliable materials having varying properties can result in a more robust protective covering. For example, the rigid material of protective plate portion 212 can substantially contribute to structurally supporting protective covering 202 and shielding a wearer from impact. In an as-worn position, surface 242a of protective plate portion 212 may face away from an individual, such as individual 100 of
The pliable material of edge portion 210 can substantially contribute to absorbing the impact. Furthermore, the pliable material can be configured to engage the wearer of protective covering 202, such as individual 100, as indicated in
Due to the strenuous nature of physical activities there is a risk that the rigid and pliable materials unintentionally separate, thereby compromising the integrity of the protective covering. In accordance with implementations of the present disclosure, the protective covering can include a coupling region that substantially reduces the risk of the rigid and pliable materials unintentionally separating.
Coupling region 220 is transitioning from the pliable material of edge portion 210 to the rigid material of protective plate portion 212. In the present implementation, coupling region 220 is continuous with the pliable material that makes of edge portion 210, and is further continuous with the rigid material that makes of protective plate portion 212.
Referring to
Coupling region 220 is adapted to provide a large contact area between the pliable and rigid materials resulting in a strong bond between edge portion 210 and protective plate portion 212, which reduces the risk of unintentional separation between the pliable and rigid materials. Furthermore, coupling region 220 has torsion regions 228a and 228b, which may be generated by bending surfaces 224a and 224b and are typical regions at which protective covering 202 may be subjected to high torsion during physical activity of a wearer. Due to the composition of those regions, torsion regions 228a and 228b are structurally resilient, particularly in relation to regions adjacent graded interface 230. Therefore, the risk of unintentional separation between the pliable and rigid materials is further reduced.
Coupling region 220 can include graded interface 230 between the pliable material and the rigid material, which is sloped to form a large contact area as opposed to being substantially perpendicular to the surface 224a and the surface 224b. While graded interface 230 is curved or sloped as shown, graded interface 230 could optionally include one or more steps along its extent. Graded interface 230 spans edges 222a and 222b of coupling region 220. As shown, graded interface 230 forms angle 232 with surface 224b of coupling region 220 at edge 222a. Angle 232 may remain less than 90 degrees between edges 222a and 222b, although angle 232 can vary along that extent, as shown. In various implementations, angle 232 remains 45 degrees or less between edges 222a and 222b. The length of graded interface 230 can be, for example, from approximately 8 millimeters to approximately 14 millimeters.
In some implementations, coupling region 220 is chemically and mechanically attaching edge portion 210 and protective plate portion 212. The chemical and mechanical attachment can enhance the integrity of the bond between the pliable and rigid materials. For example, in some cases, the pliable material of edge portion 210 and the rigid material of protective plate portion 212 are chemically cross-linked across coupling region 220. This can be achieved, for example, by co-molding edge portion 210 with protective plate portion 212. In particular, the pliable material (e.g., a polymer) can be co-molded with the rigid material (e.g., a semi-rigid flexible polymer) to achieve coupling region 220.
In some respects, the pliable material of edge portion 210 spaces surface 224b of coupling region 220 from individual 100 when protective covering 202 is worn by individual 100. The spacing can prevent or reduce contact between individual 100 and surface 224b, which may result in protective covering being more comfortable for individual 100 because surface 224b primarily comprises the rigid material. In some cases the spacing is achieved by providing offset 223 between surface 224b (e.g., a bottom surface) of coupling region 220 and surface 240b of edge portion 210, as indicated in

Lip 258 can form stitch groove 252 in edge portion 210. Stitching 254 can optionally be situated in stitch groove 252 so as to secure protective covering 202 to apparel, such as apparel 104 in
Rounded terminal 256 of edge portion 210 flares away from individual 100 of
In the implementation shown, the pliable material of edge portion 210 and the rigid material of protective plate portion 212 are exposed. However, either of the pliable material of edge portion 210 and/or the rigid material of protective plate portion 212 can be exposed or can be covered by other materials in various implementations.
Returning to
Surface 242b of protective plate portion 212 can optionally be curved in an unflexed position as indicated in
Referring to
As can be seen, the cross sections have multiple base curves forming lateral extents that span the outer edges of medial and lateral plate portions 506 and 508 of protective plate portion 512. Medial and lateral plate portions 506 and 508 correspond respectively to medial and lateral plate portions 106b and 108b in
Thus, in accordance with implementations of the present disclosure, a protective covering can comprise an edge portion of pliable material and a plate portion of rigid material. A coupling region can be employed that reduces the risk of the pliable material unintentionally separating from the rigid material. Therefore, the protective covering can be made robust while being structurally resilient.
