1. Field of the Invention
The present invention relates to protective athletic apparel. In particular, it relates to a protective athletic undergarment. More particularly, it relates to an article of padded moisture-wicking athletic underwear and system for sport performance monitoring of a force of traumatic impact.
2. Description of the Related Art
Padded protective athletic clothing is a well known solution to the problem of mitigating injuries sustained by participants in an athletic event. Such clothing typically consists of padding elements secured in pockets, or sewn into the outerwear fabric of athletic clothing, in order to protect an athlete from blows experienced by the wearer and delivered by other participants, or the objects of the event.
One such example is disclosed in U.S. Pat. No. 4,866,789, to Dorm, for a protective body suit formed of a stretchable material which defines a pair of leg openings, a pair of arm openings, and a neck opening. The body suit is sized and shaped to conform to the body of the user. A pair of side pads is secured to the body suit, between the arm openings and the aligned leg openings. A pair of resilient shoulder pads is secured to the body suit between the neck opening and the respective ones of the arm openings to protect the shoulders of the user. The pads are held securely in place against the body of the user during athletic activity with shoulder straps secured over the shoulders with hook and loop fasteners.
Other approaches to providing solutions to the problem of protecting an athlete from injuries associated with traumatic impact are illustrated in U.S. Pat. No. 4,100,620 to Pecoraro (a impact abosorbing vest), U.S. Pat. No. 4,185,327 to Markve (a air-cell coverall suit), U.S. Pat. No. 4,195,362 to Rolando (a impact-resistant ski jacket), and U.S. Pat. No. 3,135,961 to Roderick (a free-hanging, padded T-shirt).
While the foregoing articles of protective clothing offer some utility, what is needed is an improved article of protective underwear designed to protect a participant from a blunt force of traumatic impact, but which is flexible, conforming, light-weight, and moisture-wicking. Moreover, it is desirable to provide an article of padded moisture-wicking athletic underwear with and integrated system for sport performance monitoring of a g force of traumatic impact. The present invention satisfies these needs.
It is therefore an object of the present invention to provide an article of protective padded athletic underwear designed to protect a participant from a blunt force of traumatic impact.
It is another object of the present invention to provide an article of protective padded athletic underwear designed to protect a participant from a blunt force of traumatic impact, which is flexible, conforming, light-weight, and moisture-wicking.
It is yet another object of the present invention to provide an article of protective padded athletic underwear designed to protect a participant from a blunt force of traumatic impact, and a system for sport performance monitoring of a force of traumatic impact.
To overcome the problems of the prior art and in accordance with the purpose of the invention, as embodied and broadly described herein, briefly a protective athletic undergarment is provided. The undergarment has a moisture-wicking elastic fabric base layer configured to fit flexibly and snugly against the body of the wearer. A padding assembly has an inner polymer cushion with an interior surface attached to an outer surface of the base layer, and a rigid outer shell configured in a predetermined three-dimensional complimentary contour relative to an outer surface shape of an anatomical feature. The undergarment may include as system for sports performance monitoring of an impact delivered from another participant or the object of a sporting event.
Additional advantages of the present invention will be set forth in part in the description that follows and in part will be obvious from that description or can be learned from practice of the invention. The advantages of the invention can be realized and obtained by the inventions particularly pointed out in the appended claims.
The accompanying drawings, which are incorporated in and which constitute a part of the specification illustrate at least one embodiment of the invention and, together with the description, explain the principles of the invention.
Unless specifically defined otherwise, all technical or scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.
For the purposes of the following description, the phrase “blunt force of traumatic impact(s)” refers to those forces which are experienced by a person, including impacts, jolts or impacts resulting from normal athletic activities such as running, jumping, dropping to the ground, and making contact with a fellow participant or the object of an event such as balls, sticks, rails, boards, and surfaces, such as asphalt and ice. Examples of such athletic events include the sports of football, baseball, basketball, and hockey, but the present invention is also useful to protect persons engaged in activities such as bicycling, skating, snow boarding, motorcycle riding, and automobile racing.
The term “undergarment” means clothes that are worn under other clothes, pads, jerseys, sweaters, and pants, primarily intended for wear directly next to the skin to conform snugly and flexibly, in shape, to the torso, pelvis, and limbs of a participant. As used herein the term “undergarment” also means those articles of clothing often referred to undershirts, briefs, boxers and underpants.
Although any of the methods and materials similar or equivalent to those described herein can be used in the practice or testing of the present invention, the preferred methods and materials are now described. Reference will now be made in detail to the presently preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings, wherein like numerals represent like features of the invention.
The protective undergarment may, but need not, include both an undershirt 20 and underpants 21. Here, the moisture wicking elastic stretch material is further adapted to define a pair of leg openings and a waist opening. The underpants 21 are conforming in size and shape to fit snugly to the waist, buttocks, and thighs of the wearer. The undergarment is preferably designed in a pattern which allows for a pullover-the-body type construction of moisture-wicking fabric. Suitable fabrics are preferably based upon plaited micro fibers 23. The outer surfaces of these fabrics are preferably chemically treated with either one of a hydrophilic (water-loving) chemical, that wicks perspiration away through the fabric to the outer surface, and/or an antimicrobial agent. Examples of such fabrics, which are suitable for use, include those acrylic fabrics, derived from polyacrylonitrile, where one desires to provide a soft, washable, colorfast, synthetic fiber base layer. Other suitable fibers include polyesters, such as COMFORTREL®, a chemically treated polyester base-layer fabric made by Wellman, Inc., COOLMAX™, by Invista, a hydrophobic tetra-channel polyester which includes fiber cross sections that produce a strong wicking action, or SUPPLEX®, also by Invista, where one desires the base layer to consist of a cotton based active-ware fabric.

One or more of the padding assembly elements 30 may, but need not, include at least one impact sensor 40, and a system, for sports performance monitoring of the impact. The impact sensor 40 detects the impact, and the system quantifies, and records a magnitude, duration, and/or direction of an impact. Impact sensors 40 which are suitable for the practice of the present invention may, but need not, be self-powered. Impact recorders suitable for use with the present invention include piezoelectric sensors 42 which can be coupled to an array of tuned cantilever beams 43 of ascending length. Depending upon the intended application, the impact sensors 40 can also be integrated microelectromechanical sensors (“MEMS”) 44, with one or more elements of the sports performance monitoring system all on a single monolithic integrated circuit (“IC”) chip 45. Depending upon intended use, the IC sports performance monitoring system can include latchable memories, having first-in-first-out (“IFIO”) functionality to capture and retain impact related data, electronic circuits, microcontrollers, analog-to-digital/digital-to-analog converters, programmable digital signal processors (“DSP”), timers, filters, analog and digital inputs and outputs, and a battery 46 so that the system is capable of sensing, recording, converting, processing, outputting, and transmitting impact telemetry related data. Some or all of these elements of the system are housed, or integrated, in one or more of the padding assembly cushion 32 and/or outer shell 34.
Piezoelectric thin film impact sensors 42 are well known. Such sensors may be manufactured using impact sensing elements, such as a piezoelectric material sandwiched between two electrode layers. The electrode layers can be platinum and the piezoelectric material can be PZT, BaTi O3, ZnO, MN, or PbNiNbO. Other similar or compatible materials for the electrodes and piezoelectric material can also be considered to fall within the scope of the present invention. The piezoelectric materials are typically deposited on the alloy by RF reactive magnetron sputtering. One example of an electromechanical impact recorder, capable of for modification for any intended event is to provide an electromechanical cantilever beam self-powered piezoelectric shock sensor disclosed in U.S. Pat. No. 8,191,421, to Petelenz, et. al, This disclosure is incorporated by reference as though fully set forth herein. Here, the combination of a self-power piezoelectric sensor 42 coupled to an array of ascending length cantilever beam resonators 43 provides a tunable resonate response, with an inherent predetermined threshold interrupt value, to enable the sports performance impact monitoring, in a predetermined range, of those g forces which are characteristically encountered by a participant 10 engaged in any given event. This example is particularly suitable for use in monitoring those events which are characterized by a random, high magnitude, short duration degree of impacts, with an event-specific threshold resonance trigger that does not require external power to detect and record the magnitude of the impact event.
In another example, the presently preferred embodiment includes the use of integrated microelectromechanical MEMS semiconductor technology which combines the microelectromechanical accelerometer structures 44 and electrical circuits on a single silicon chip. The silicon chip is integrated within, or attached to, a padding assembly element. The integrated MEMS accelerometers 44 may sense acceleration on one, two, or even three axes, and provide either analog or digital outputs. Depending upon intended use, the accelerometer 44 may offer different ranges of detection, from several g to tens of g. Digital versions can be also be configured with multiple interrupt modes. Again, dependent upon intended use, a wide variety of integrated microelectromechanical MEMS sensors are suitable for use with the present invention including those manufactured under the Mark iMEMS®, owned by Analog Devices, Inc., of Norwood, Mass., USA.
It is also within the scope of the present invention embodiments where the integrated MEMS accelerometers 44 is a 3-axis microelectromechanical accelerometer structure attached to the padding assembly 30, 30 where one desires to detect changes in impact which are relative to body position of a participant, by tracking acceleration changes in three orthogonal directions. 3-axis MEMS accelerometers are also available from Analog Devices, Inc. in various configurations. For example, 3-axis devices can includes a selectable ±2-g, ±4-g, ±8-g, or ±16-g measurement range; resolution of up to 13 bits; fixed 4-mg/LSB sensitivity; a tiny 3-mm×5-mm×1-mm package; ultralow power consumption (25 μA to 130 μA); standard I2C and SPI serial digital interfacing; and 32-level FIFO storage. A variety of built-in features may, but need not, include motion-status detection and flexible interrupts. With this system, the impact data is continuously analyzed algorithmically to determine whether, using the impact date relative to the motion and body position of the participant 10, the participant 10 is subject to impact, the maximum or absolute force of impact, impact duration, and location of impact, and, with a wireless transmitter, issue a status alert.
With another example, where the three-dimensional contour of the padding assembly 30 consists of a dynamic tiling array of smaller uniform padding assembly elements 30, it may be desirable to integrate, within the cushion 32 and/or outer shell 34 of the padding assembly 30, an arrangement of integrated single-axis high-g, and low-g MEMS accelerometers 44 about predetermined positions of the exterior anatomy of a participant 10 to monitor impacts received in differing orthogonal directions. Moreover, at least some of the single-axis integrated accelerometers 44 are desirably configured in an analog sensor platform which allows the user to program the integrated MEMS device with analog out so that one is capable of outputting the entire window of impact related information in real time.
