DETAILED DESCRIPTION
Several embodiments of the invention are described in detail below with reference to the accompanying drawings. The drawings show embodiments of the invention drawn to scale. The embodiments as shown in the figures and discussed below are exemplary of the invention and do not limit the scope of the invention to that explicitly shown or described.
With reference to the drawings, one embodiment of this invention includes a protective garment (e.g., girdle) 1 having a body portion 1a and a pair of left and right leg portions 1b. The body portion 1a includes a flexible waist band adapted to surround a person's (athlete) abdomen. The leg portions 1b extend above the person's knees and surround the person's thighs. However, the leg portions may also be designed to extend past the knees. The garment 1 is made from elastic, washable and durable fabric. An example of such fabric is Lyrcra®, Spandex, and/or mesh. A plurality of pads are provided at locations of the garment 1 to absorb impact forces, such as from direct or indirect contact with opposing player(s), object(s), or ground surface. The locations of the pads are selected to protect the person's thighs, hips, and tailbone.
As shown in FIGS. 1 and 3, the body portion 1a includes left and right hip pads 3 and a tailbone pad 5. As shown in FIG. 2, the leg portions 1b includes left and right thigh pads 7. As shown in FIGS. 6-12, the thigh pad 7 comprises a foam part 7a and a thigh pad plate 7b. The thigh pad foam part 7a, hip pads 3, and tailbone pad 5 may be formed from a known foam type, including EVA, LDPE, HDPE, PU, VN, or visco-elastic foam. These components may be formed by heat compressed foam, molded, or injection foam. The foam thickness may be 5-20 mm, preferably 8-12 mm, most preferably 10 mm. The thigh pad plate 7b may be formed from a known hard plastic material, such as ABS, PP, HDPE, PC, or a composite (glass or carbon based), or any of blend of these resins, or any of these resins mixed with 0-15% glass or carbon reinforcement.
One objective of the novel design for the various pad features included in the protective garment described herein is to allow a user's body heat to efficiently and effectively exit the user's body surface even in locations of the user's body that are covered, padded, and protected. The pad design allows for moisture management properties and tactical impact energy dispersion.
FIG. 13 illustrates an embodiment of a pattern used to form the protective garment 1. The pattern includes a plurality of cut lines and fold lines designed to form the overall shape of the protective garment and to accommodate the pads attached (stitched) to an outside surface of the protective garment 1. The protective garment 1 includes several panel portions separated by cut lines. The panel portions may be formed of mesh or lycra material, depending on the desired function of the panel portion.
FIG. 14 illustrates a foam part 7a of left thigh pad 7, without the pad plate 7b. As shown in section A-A′, the foam part 7a is formed with a plurality of channels 7c, pad plate accommodating portion 7b′, and a plurality of cutout portions 7d. The thickness of foam part 7a may be 5-20 mm, preferably 8-12 mm, most preferably 10 min. In this embodiment, the foam plate accommodating portion 7b′ is a recessed portion having a depth of 3 mm and thickness of 7 mm; however, it is known to use a dimension suitable to accommodate a desired pad plate 7b thereon. Each of the channels 7c is preferably 5 mm deep and formed such that at least 2 mm of material remains at an upper surface thereof. For example, in the portion of 10 mm foam part 7a that is not the foam plate accommodating portion 7b′, the channel is formed 5 mm deep and there is 5 mm of material remaining at an upper surface thereof. As shown in section B-B′, the plurality of cutout portions 7d are formed as vertical through-holes extending from the upper surface through a lower surface of the foam part 7a. The plurality of cutout portions 7d are formed on the entire foam part 7a, including the pad plate accommodating portion 7b′. Each of the plurality of cutout portions 7d may be configured of the same shape or different shapes (e.g., aesthetics). In this embodiment, for example, the cutout portions are formed in rows of mostly triangular shaped cutouts having rounded edges wherein the shapes of the cutout portions in adjacent rows are formed generally as mirror-images from one another.
It is important to arrange the cutouts in a manner that protects the user (e.g., tactical impact energy dispersion), allows the user's skin to effectively and efficiently breathe and release heat, and reduces the weight of the pads and covering. This can be accomplished by designing a pad with the most amount of cutouts in the padding and covering without compromising the protection to the player (e.g., structural integrity of the pad).
FIG. 15 illustrates a top and bottom view of the left thigh pad foam part 7a, before and after a die cut process used to form the plurality of cutout portions 7d. As shown in the top view before die cut, the pad plate accommodating portion 7b′ in this embodiment is a 3 mm recess designed to fit the pad plate 7b. The thigh pad 7 includes a stitching tab portion 7e formed along the contour of the thigh pad 7. The stitching tab portion 7e is preferably formed free of cutout portions 7d in order to allow for continuous stitching of the thigh pad 7 to the protective garment 1 along the entire contour of the thigh pad 7.
FIG. 19 illustrates a thigh pad plate 7b. The thigh pad plate 7b is arranged (e.g., stitched) on a top of pad plate accommodating portion 7b′. The thigh pad plate 7b may be made with a flexible plastic material that has a certain amount of flexibility and that is stitchable for stitching the thigh pad plate 7b to the foam part 7a. The thigh pad plate 7b may alternatively include holes formed on a contour thereof to allow for stitching the pad plate 7b to the foam part 7a. However other known attaching means can be used to attach the pad plate 7b to the foam part 7a. For example, the pad plate 7h may be inserted into pockets on the foam part 7a or protective garment 1.
The thigh pad plate 7b may be formed from a known hard plastic material, such as ABS, PP, HDPE, PC, or a composite (glass or carbon based), any of blend of these resins, or any of these resins mixed with 0-15% glass or carbon reinforcement. A plurality of spaced-apart cutout portions 7d′ is formed in the thigh pad plate 7a. The pad plate 7b is located on a surface of the thigh pad 7 so that each of the cutout portions 7d′ are arranged generally in line with the corresponding underlying cutout portions 7d of the foam part 7a, as shown in FIGS. 1, 2, and 6-10. The cutout portions 7d′ of the thigh pad plate and the cutout portions of the foam part 7a may be formed in a grid pattern. According to this embodiment each of the cutout portion 7d′ is formed to taper inward. Each cutout portion 7d′ is spaced apart approximately 6 mm from each adjacent cutout portion 7d′ and is approximately 6 mm in depth. However, a dimension suitable to mate with the corresponding foam part 7a and to provide adequate structural integrity for the desired impact absorption properties can be used.
The cutout portions 7d′ of pad plate 7b provide a large amount of ventilation while still providing strength for impact protection. As shown in FIG. 7, the cutout portions 7d′ of the pad plate 7b provide a certain opening percentage relative to the total surface in a zone defined by the outer perimeter of the pad plate 7b cutout portions 7d′. FIG. 8 shows the inner surface of the foam part. In FIG. 8, the inner openings of the cutout portions of the pad plate 7b correspond with the cutout portions of the foam part 7a excluding the cutout portions grouped together along the right edge of the foam part.
The opening percentage calculated based on the inner openings of cutout portions 7d′ relative to the total surface in the zone defined by the outer perimeter of the cutout portions 7d′ of pad plate 7b on the inner surface (leg side) is preferably 10% or more preferably 15% or more, more preferably 20% or more. The opening percentage of the inner opening of cutout portions 7d′ is preferably 50% or less, more preferably 40% or less, more preferably 30% or less, more preferably 25% or less. FIG. 7 shows an opening percentage of 22% for the inner openings of cutout portions 7d′ relative to the total surface in the zone defined by the outer perimeter of the cutout portions 7d′ of pad plate 7b.
The channels in the thigh pad plate 7b provide ventilation and also disperse impact energy to the foam part 7a more efficiently than a solid hard plate. Moisture-wicking technology in the fabric of the protective garment 1 is designed to remove sweat and to accelerate evaporation and cooling. Mesh panels, e.g., polyl spandex, enhance ventilation to keep the user's core body temperature generally consistent and cool. Compression fabric portions of the protective garment are provided to contour to the user's body for optimal fit and improved range of motion. Flat seam, design of the protective garment 1 is designed to diminish irritation during movement. The protective garment 1 and pads may include anti-microbial treatment to reduce odor causing bacteria.
FIG. 16 illustrates a left side hip pad 3. As shown in section A-A′, the hip pad 3 is formed with a plurality of channels 3c, a plurality of cutout portions 3d, and a contour stitching tab 3e. The hip pad 3 may include a horizontal channel 3b, preferably 5 mm thick extending horizontally from one end portion of the hip pad 3 to the opposite end portion of the hip pad 3. The thickness of hip pad 3 may be 6-20 mm, preferably 8-12 mm, most preferably 10 mm. Each of the channels 3c is preferably 5 mm deep and formed such that at least 2 mm of material remains at an upper surface thereof for structural integrity. For example, in the portion of 10 mm hip pad 3 including a channel formed 5 mm deep, the vertical portion above the channel is 5 mm thick. As shown in section B-B′, the plurality of cutout portions 3d are formed as vertical through-holes extending from the upper surface through a lower surface of the hip pad 3. As shown in FIG. 16, the contour stitching tab portion Se is formed along the contour of the hip pad 3. The stitching tab portion 3e is preferably formed free of cutout portions 3d in order to allow for continuous stitching of the hip pad 3 to the protective garment 1 along the entire contour of the thigh pad 3. Each of the plurality of cutout portions 3d may be configured of the same shape or different shapes. In this embodiment, for example, the cutout portions are formed in rows of mostly triangular shaped cutouts having rounded edges wherein the shapes of the cutout portions in adjacent rows are formed generally as minor-images from one another.
FIG. 17 illustrates a top and bottom view of the left hip pad 3, before and after a die cut process used to form the plurality of cutout portions 3d.
FIG. 18 illustrates a tailbone pad 5. The tailbone pad 5 is funned with a plurality of channels 5c, a plurality of cutout portions 5d and a contour stitching tab 5e. The thickness of tailbone pad 5 may be 6-20 mm, preferably 8-12 mm, most preferably 10 mm. Each of the channels 5c is preferably 5 mm deep and formed such that at least 2 m of material remains at an upper surface thereof for structural integrity. For example, in a 10 mm portion tailbone pad 5 including a channel formed 5 mm deep, the vertical portion above the channel is 5 mm thick. The plurality of cutout portions 5d are formed as vertical through-holes extending from the upper surface through a lower surface of the tailbone pad 5. The contour stitching tab portion 5e is formed along the contour of the tailbone pad 5. The stitching tab portion 5e is preferably formed free of cutout portions 5d in order to allow for continuous stitching of the tailbone pad 5 to the protective garment 1 along the entire contour of the tailbone pad 5. Each of the plurality of cutout portions 5d may be configured of the same shape or different shapes. In this embodiment, for example, the cutout portions are formed in rows of mostly triangular shaped cutouts having rounded edges wherein the shapes of the cutout portions in adjacent rows are formed generally as minor-images from one another.
FIG. 20 is a drawing illustrating an assembly of the thigh pad plate 7b to the thigh pad foam 7a, and the thigh pad 7 to the protective garment 1. As illustrated, the thigh pad plate 7b is attached to the pad plate accommodating portion 7b′ of the foam part 7a so that each of the cutout portions 7d′ are arranged generally in line with the corresponding underlying cutout portions 7d of the foam part 7a, as shown in FIGS. 1, 2, and 6-10. The pad plate 7b may be attached to the foam part 7a by stitching the pad plate 7b to pad plate accommodating portion 7b′ of the foam part 7a via the holes formed in the stitching tab portion 7e. The thigh pad 7, integrally comprising the foam part 7a and plate portion 7b, is then attached to the protective garment. The thigh pad 7 may be attached to the protective garment 1 by placing the thigh pad 7 on an inner side of a desired location on the protective garment 1, preferably floating mesh layer, and performing a flatlock (flatseam) contour seam. However, other known methods, such as cover stitching and overlocking may be performed. The hip pad 3 and tailbone pad 5 may also be attached to the protective garment 1 by placing the respective pad on an inner side of a desired location on the protective garment 1, preferably floating mesh layer, and performing a flatlock (flatseam) contour seam.
