This disclosure relates to protective garments.
Many protective garments are large, bulky, and have poor ventilation. This makes it difficult to wear such protective garments for a long period of time such as, for example, during a work shift. Thinner, better ventilated protective garments exist and are easier to wear for extended periods of time, but such protective garments provide less protection to the wearer.
One particular area where thinner protective garments pose a problem is with clamping forces, such as those caused by the bite of a mammal or other animal. In the event of such a clamping force, the wearer may be unable to rotate an appendage, such as an arm or leg. Rotation of an appendage during a biting situation can be beneficial to twist an appendage out of the mouth of a biting mammal or other animal, take other action against the biting mammal or other animal, escape, or otherwise end the biting situation. For example, a wearer may be unable to reach or manipulate a walkie-talkie, door handle, or take action against the biting mammal or other animal if the wearer is unable to rotate the appendage being bitten.
Therefore, what is needed is an improved protective garment.
The protective garment disclosed herein includes integrated metal mesh regions. The protective garment may be a shirt, pants, or one-piece suit with both shirt and pants. The integrated metal mesh regions may be positioned in the appendages of the protective garment (i.e., sleeves and/or legs). The protective garment can provide cut, slash, abrasion, and/or wear resistance. The protective garment also can protect a wearer against clamping forces, such as biting by a mammal or other animal (e.g., human, dog, etc.). In the event of a bite, the protective garment provides a rotational degree of freedom for a wearer to rotate his or her appendage in spite of the clamping force of the bite. The wearer can, for example, twist or pull his or her appendage out of the mouth of the biting mammal or other animal. The wearer also can take other action against the biting mammal or other animal, escape, or otherwise end the biting situation. Damage to the teeth of the biting mammal or other animal is lessened or prevented because of the fabric of the protective garment.
For a fuller understanding of the nature and objects of the disclosure, reference should be made to the following detailed description taken in conjunction with the accompanying drawings, in which:
Although claimed subject matter will be described in terms of certain embodiments, other embodiments, including embodiments that do not provide all of the benefits and features set forth herein, are also within the scope of this disclosure. Various structural changes may be made without departing from the scope of the disclosure.
The protective garment disclosed herein has a core region and appendage regions. For example, the core region may fit around a human torso and the appendage regions may each fit around a human arm. Integrated metal mesh regions may be positioned in these appendage regions.
The protective garment includes an outermost layer, an innermost layer, and a metal mesh layer. The metal mesh layer is disposed between the outermost layer and innermost layer in the appendage regions and may cover a fraction or an entirety of an appendage region. The coefficients of static and kinetic friction, dimensions, and/or attachment configurations for the various layers enable the metal mesh layer to slide or otherwise translate. Thus, most or all of the protective garment can provide cut, slash, abrasion, and/or wear resistance and the protective garment can protect a wearer against clamping forces, such as biting by a mammal or other animal (e.g., human, dog, etc.) on the appendage regions. In the event of a bite or other clamping force, the protective garment provides a rotational degree of freedom for a wearer to rotate his or her appendage in spite of the clamping force. The wearer also may have the ability to move his or her appendage forward or backward (i.e. in a direction perpendicular to the axis of rotation) in spite of the clamping force of the bite.
The following description includes multiple exemplary embodiments. Other designs or configurations are possible.
The appendage regions 102 can be, for example, raglan sleeves. Each of the appendage regions can define a thumbhole and one or more finger holes (i.e., one to four finger holes). Each finger hole can enable one to four fingers to project therethrough. Other wrist configurations are possible. For example, each appendage region 102 may have a simple wrist hole for a human hand rather than a thumb hole and/or finger holes.
The outermost layer 105 of the protective garment 100 seen in
The outermost layer 105 may have a uniform thickness or non-uniform thickness. The number of layers of fabric chosen for the outermost layer 105 in each region of the protective garment 100 may depend on the importance of ventilation or the concern of slash or cut resistance in the particular region. For example, the outermost layer 105 can have three layers of fabric in the forearms of the appendage regions 102, two layers of fabric in the upper arms of the appendage regions 102, and one layer of fabric in the first side and second side of the core region 101.
The outermost layer 105 provides a high level of cut, slash, abrasion, and wear resistance. For example, the outermost layer 105 may provide ANSI Level 4 cut resistance. The styling and fit can help conceal areas having added protection and enable the protective garment 100 to resemble a normal shirt, jacket, or sweater. For example, an observer may not distinguish a difference in the number of layers that comprise the outer most layer 105 in each region of the protective garment 100.
The innermost layer 106 may be machine knitted or woven and can include a polyester fabric. For example, the innermost layer 106 can be made of a COOLMAX® yarn, manufactured by Invista, or other fibers. These fibers may be a staple spun construction. This innermost layer 106 may offer comfort and moisture wicking ability.
The metal mesh layer 107 can include a surgical grade high-strength steel, which may be in the form of individually-welded steel rings. In an example, the metal mesh layer 107 is 316L surgical grade stainless steel.
The thickness or other dimensions of the metal mesh layer 107 can vary. In an example, the metal mesh layer 107 has 0.021 inch (0.533 mm) wire thickness, 0.0158 inch (4 mm) outer ring diameter, 0.118 inch (3 mm) inner ring diameter, and has 0.575 lb/ft2 mesh weight. In another example, the metal mesh layer 107 has 2.4 mm inner ring diameter and 4 mm outer ring diameter. Other wire thicknesses, ring diameters, or weights are possible. Use of surgical grade high-strength steel can increase product lifespan and durability.
The metal mesh layer 107 provides puncture, cut, and slash resistance. It can protect against mammal or other animal bites, knives, and other sharp objects.
The innermost layer 106 is connected to the protective garment 100 at a seam 108 between the appendage region 102 and the core region 101 and extends distally. The innermost layer 106 may extend along the entirety of the appendage region 102 and connect to the protective garment 100 at the wrist 109, which also may include a seam. In an instance, the innermost layer 106 is only connected to the protective garment 100 at the seam 108 and at the seam in the wrist 109. In a particular example, the innermost layer 106 connects at the wrist 109 along the same seam as the outermost layer 105. The innermost layer 106 can extend to the armpit running along the length of the underarm and then perpendicular along the edge of the metal mesh layer 107 at the wrist 109.
In an embodiment, the metal mesh layer 107 extends from a wearer's shoulder to wrist. Thus, the metal mesh layer 107 may be attached to the outermost layer 105 at the seam 108. The metal mesh layer 107 may not be attached directly to the innermost layer 106. The metal mesh layer 107 may be made lighter if it extends from a wearer's shoulder to wrist, such as by using a lighter steel.
The metal mesh layer 107 also may be connected to the protective garment 100 at the wrist 109 of the appendage region 102 and may extend partly toward the seam 108. For example, the metal mesh layer 107 may only extend to cover a wearer's forearm. This metal mesh layer 107 may only be attached to the outermost layer 105 using, for example, straight needle stitching at the wrist 109 and at another point partway to the seam 108. In an example, the metal mesh layer 107 may only be attached to the outermost layer 105 at the wrist 109 and at another point partway to the seam 108. Additional attachment points for the metal mesh layer 107 are possible, such as along an underarm seam.
Thus, the innermost layer 106 is disposed around a wearer's upper arm and forearm while the metal mesh layer 107 may be disposed only around the wearer's forearm or around the wearer's forearm and upper arm. The metal mesh layer 107 may be disposed around 360° of the appendage region 102. Thus, an entire circumference of a wearer's forearm or forearm and upper arm is covered by the metal mesh layer 107.
The length of the metal mesh layer 107 can vary. For example, the metal mesh layer may be at least 6 inches long as measured from where the metal mesh layer 107 is connected to the outermost layer 105 at the wrist 109.
The metal mesh layer 107 may be loose. Thus, the metal mesh layer 107 is free to slide or otherwise translate with respect to the outermost layer 105 and/or innermost layer 106 except where the metal mesh layer 107 is connected to the outermost layer 105.
In an embodiment, the metal mesh layer 107 also may be connected to the outermost layer 105 along a length between the two radial connections to the outermost layer at the wrist 109 and the other point toward or at the seam 108. Thus, a linear connection to the outermost layer 105 may be formed along the length of the appendage region 102 between the two circumferential connections at the ends of the metal mesh layer 107.
In an embodiment, the metal mesh layer 107, innermost layer 106 and outermost layer 105 can extend over a dorsal side of a wearer's hand.
The side 110 and opposing length formed by sides 113, 114, 117 and the side 111 and opposing side 112 may change to suit the size of the protective garment. For example, these lengths each may change approximately 1 inch when changing between a large and medium or a medium and small protective garment.
The metal mesh layer 107 is configured to roll and slide between the innermost layer 106 and the outermost layer 105. This may be partly due to the metal mesh layer 107 only being attached to the outermost layer 105 at two, three, or more seams, though other mechanisms are possible. The metal mesh layer 107 can have an approximately equal or a lower coefficient of static friction and kinetic friction compared to the innermost layer 106 and the outermost layer 105. The innermost layer 106 and the outermost layer 105 also can have low coefficients of static friction and kinetic friction to enable rotation and translation between the three layers.
Use of the metal mesh layer 107 in the protective garment 100 provides at least 20% rotation of the innermost layer 106 relative to the metal mesh layer 107 when a clamping force is applied to the outermost layer 105. Thus, the innermost layer 106 may have a rolling degree of freedom relative to the metal mesh layer 107 or the metal mesh layer 107 and outermost layer 105 between approximately 20° and 100°.
This rolling degree of freedom may be a function of the design of the protective garment 100 and the appendage 119. Factors that affect the degree of freedom include the amount of slack, whether the bite or clamping force is at the top or bottom of the appendage, dimensions of the appendage 119, distance between seams of the metal mesh layer 107, dimensions of the rings in the metal mesh layer 107, dimensions of the mouth or teeth of the mammal or other animal that is biting or applying the clamping force, or the dimensions of the metal mesh layer 107.
The appendage may be a forearm. For example, is a 7.5 inch circumference forearm may have approximately 90° of rotation when the forearm clamped due to biting. In another example, a 15 inch circumference forearm may have approximately 45° of rotation when the forearm clamped due to biting. In both examples, the forearm is clamped on the side, approximately midway between wrist and elbow.
The metal mesh layer 107 can be configured to be inconspicuous, which allows the protective garment 100 to resemble a normal shirt, jacket, or sweater. Such a configuration may be advantageous for the individual wearing the protective garment as the mammal or other animal that may bite the individual may not be able to distinguish the protective garment from a non-protective garment, and may not be able to target areas of the protective garment that do not include metal mesh layer 107.
While a metal mesh layer 107 is disclosed, other materials can be used. For example, a plastic coated fabric or formed steel or plastic piece can be used instead of or to supplement the metal mesh layer 107.
The metal mesh layer 107 may protect the wearer from various injuries. For example, the wearer may be protected from any cutting or puncturing that may otherwise break skin. In the event of a clamping force, the metal mesh layer 107 may reduce bruising to the wearer's forearm or any other protected area.
While a protective garment 100 for a human torso, such as a shirt, jacket, or sweater, is disclosed, other variations are possible. For example, pants with metal mesh protecting the calves or calves and upper leg are possible. A one-piece suit that protect both arms and legs, smocks that protect arms, or an apron covering the legs also are possible. Embodiments that do not include a core region, only appendage regions, are possible. Additional protection to other regions using a metal mesh layer 107, such as hands, feet, or groin, also is possible.
The protective garment disclosed herein has multiple uses. For example, workers (such as teachers, hospital personnel, aides, or others) helping those with special or exceptional needs can benefit from the extra biting protection provided by an embodiment of this protective garment. Special or exceptional needs can include persons with, for example, behavioral, psychological, or developmental issues. Police, security guards, or prison workers also may benefit from extra biting protection provided by an embodiment of this protective garment. Others who may benefit from embodiments of this protective garment include dog trainers or handlers, veterinary workers, zoo or aquarium workers, animal control workers, or those who handle, for example, birds of prey, ferrets, monkeys, rodents, or cats. Others with a propensity to be bitten also may benefit from an embodiment of the protective garment disclosed herein. Others who may benefit from the protective garment include those who seek protection from injuries resulting from clawing, pinching, abrasives, puncturing, or slashing.
Although the present invention has been described with respect to one or more particular embodiments, it will be understood that other embodiments of the present invention may be made without departing from the spirit and scope of the present invention. Hence, the present invention is deemed limited only by the appended claims and the reasonable interpretation thereof.
