DETAILED DESCRIPTION

Aspects of various embodiments are described through reference to the drawings.

Referring now to FIGS. 1A, 1B and 1C, an exemplary safety garment 10 of the present disclosure is shown. The garment 10 may be configured to protect the user from one or more potential dangers in a hazardous environment, including but not limited to flammables, chemicals, heat, fire, oil, steam and objects, while allowing some flexibility, manoeuverability and comfort. The garment 10 comprises a covering, for example in some aspects a first covering 12 configured to cover at least part of a torso of a wearer, and a second covering 14 configured to cover at least part of a limb of the wearer. The garment 10 may further comprise additional coverings, for example in respect of hands, feet and face/head. A limb may be an arm, leg or lower extremity, for example hips and legs, of a human wearer or an animal. Safety garment 10 may further comprise a first flexible panel 16 extending from the first covering 12 to the second covering 14 and interconnecting the first covering 12 to the second covering 14. The first flexible panel 16 may completely surround a limb passage 19 in garment 10, which is adapted to receive the limb of the wearer. The limb passage 19 may be a passage or channel that enables a wearer to insert their limb therethrough into the second covering 14. Since limb passage 19 may be disposed inside garment 10, it is illustrated using a stippled line in FIGS. 1A-1G.

In some embodiments, a mechanical property of the first flexible panel 16 may be different than that of the first covering 12 and that of the second covering 14. For example, and without being limiting, the mechanical property may be elastic modulus, which is representative of the ability of flexible panel 16 to being deformed elastically (i.e., non-permanently) when a force is applied to it. In some embodiments of the present disclosure, the elastic modulus of the first flexible panel 16 is lower than that of the first covering 12 and that of the second covering 14.

The mechanical property may be flexibility, wherein the first flexible panel 16 is more flexible than the first covering 12 and the second covering 14.

The first flexible panel 16 may be disposed in various locations of safety garment 10 to facilitate movement of a limb and to accommodate relative movement between the first covering 12 and the second covering 14. For example, and without being limiting, the first flexible panel 16 may be disposed in a shoulder region 20 of the safety garment, as is shown in FIGS. 1A, 1B and 1C. The shoulder region 20 substantially corresponds to the locations on the safety garment 10 which are proximate to a wearer's shoulders when the garment is worn by the wearer. The shoulder region 20 may include region on either side a wearer's shoulder joints when wearing the safety garment 10, and may include any of the front, side and rear of the safety garment 20. Alternatively, the first flexible panel 16 may, for example, be disposed in a hip region 24 of the safety garment 10, as is shown in FIGS. 1D and 1E. The hip region 24 may substantially corresponds to a location on the safety garment 10 which are proximate to the wearer's hip when the safety garment 10 is being worn. The hip region 24 may include any of the front, sides and back of the safety garment 10. Garment 10 may further comprise at the hip region 24 an adjustable belt which may fully or partially encircle the waist of the wearer and cinch up the suit at the hips to the wearer's desired comfort. The belt may be elastic, an adjustable belt and buckle configuration, or hook and loop fabric type configuration.

Referring now to FIGS. 1F and 1G, in some embodiments, safety garment 10 may further comprise a second flexible panel 18 disposed in a second region of the safety garment, for example wrist region 22, which substantially corresponds to a location on the safety garment 10 which is proximate to a wearer's wrists when the garment 10 is worn by the wearer, or ankle region 26, which substantially corresponds to a location on the safety garment 10 which is proximate to a wearer's ankles when the garment 10 is worn by the wearer.

The second flexible panel 18 may be configured to interconnect the second covering 14 to another garment, for example a boot, helmet or a glove. The second flexible panel disposed in the second region may partially surround a passage for entry of a foot, head or hand formed between the second covering 14 and the boot, helmet or globe. The boot, helmet or glove may be made to be specifically compatible in terms of fit, colour, and materials with safety garment 10 so as to present a set of accessories for use with safety garment 10.

The garment 10 may be manufactured in a variety of different sizes and configurations suitable for users of various sizes, shapes and needs. Garment may comprise, for example, a shirt, sweater, turtleneck, trousers, jacket, coat. First covering 12 may, for example, resemble a vest or alternatively may cover a larger portion of the wearer's body. Materials suitable for first covering 12 and second covering 14 include, but are not limited to, conventional materials typical of casual, technical or other clothing or garments, for example cottons, polyesters, synthetic or natural materials or fabrics. Coverings may also be protective coverings comprised of protective materials, for example Kevlar™, Indura UltraSoft™, Nomex™, Gore-Tex™ and 3M Thinsulate™ Quilt Lining, as well as any material suitable for the intended use of the garment 10 by the wearer. Materials may preferably be flam e-resistant, and may either be inherently flame resistant or be treated. Inherently flame resistant fibers are materials that have flame resistance built into their chemical structures, for example Kevlar™ and Nomex. Treated materials are made flame-resistant by the application of flame-retardant chemicals. A chemical additive in the fiber or treatment on the fabric is used to provide some level of flame retardancy. Alternatively, covering may be made of material that is waterproof, windproof, vapor or hot steam proof, or heat proof, or a material that has all these characteristics. In addition, covering may further comprise one or more reflectors, lights, or other visibility devices or markings to increase visibility of the wearer in certain circumstances.

In some embodiments, first covering 12 and/or second covering 14 may comprise a trilaminate including: an internal insulating layer, an intermediate vapour barrier and an external flame and water resistant layer. In some embodiments, the first flexible panel 16 and/or second flexible panel 18 comprise an elastomer fabric. Elastomer fabrics, for example, are those fabrics that possess the capability of elongation and yet may recover substantially fully and rapidly from elongations. In other aspects, first flexible panel 16 and second flexible panel 18 may, for example, be spandex or Lycra™.

External surfaces of safety garment 10 may also have reflective tape distributed thereon. Various linings may also be used in conjunction with first covering 12 and second covering 14, for example insulating lining, comfort lining, mesh lining, heat diffusing liners, moisture wicking liners, or any other lining suitable for the intended purposes of the garment 10 by the wearer or as desired by the wearer.

In some embodiments, first flexible panel 16 and/or second flexible panel 18 may comprise a 4-way stretch fabric. 4-way stretch fabrics may be characterised in that a given portion of fabric is able to be stretched lengthwise and widthwise while substantially returning to its original size after stretch.

Safety garment 10 may have one or more pockets 28 of varying sizes and shapes distributed on or within first covering 12, second covering 14 or disposed on or in an optional liner, and configured to carry a variety of tools, materials or any other such objects the user wishes. Pockets 28 may be constructed from any suitable material, including and not limited to a mesh material, or, for example, the same material comprising first covering 12 and second covering 14. Mesh material enabling the detection of gases therethrough utilizing a gas detection device may also be preferred. Pockets 28 may also secure objects stored within them, for example, and without being limiting, with a flap secured, for example, with a button, snap, Velcro™ or other fastening instrument. Pockets 28 may also be ergonomically angled to provide better accessibility by the user.

Safety garment 10 may also be secured on the user to allow the user to easily put on or remove safety garment 10, and to provide a secure fit, using a fastening device that is releaseably securable, for example and without being limiting, a snap, buttons, zipper, Velcro™ or combinations of these.

In operation, safety garment 10 comprising first flexible panel 16 may facilitate movement of the limb of the wearer relative to the torso of the wearer by accommodating relative movement between the first covering 12 and the second covering 14, when the safety garment 10 is being worn by a wearer. First flexible panel 16 and/or second flexible panel 18 may enable flexibility, fit and movement for the wearer while maintaining coverage and protection for the wearer, from, for example, high heat or hot steam projected towards the wearer. When exposed to potentially dangerous environmental conditions, for example high-heat steam or fire, safety garment 10 may be able to provide some coverage to the wearer's potentially vulnerable areas, for example shoulder region 20, hip region 24, wrist region 22 and ankle region 26. Safety garment 10 may maintain a close fit to wearer's body despite some of the wearer's movement or shape, and enable the first and second coverings 12, 14, preferably being flame-resistant, to protect wearer to some degree from the high heat. In the event that wearer is being subjected to hot steam, close fitment of the safety garment 10 to the wearer via first flexibility and second flexibility panels 16, 18 will, to some degree, inhibit steam from entering into or getting through safety garment 10 and causing damage or injury to the wearer.

Referring now to FIGS. 2A, 2B and 2C, a safety garment 100 according to another embodiment is shown. Safety garment 100 may possess one or more of the elements described above in respect of safety garment 10.

Communication device 60 may be a device configured to communicate, for example by sending or receiving, the event to a remote communication device. Communication device 60 may send the event detected by sensor 54 to a remote communication device, perhaps notifying off-site personnel of specific environmental conditions or of the need for emergency help for the wearer in case of a sudden increase in ambient temperature, perhaps signalling a fire, or a trip or fall of the user, or the user departing from an expected course or path typical of their duties. Communication device 60 may, without being limiting, be a Wi-Fi transmitter, a Radio Frequency (RF) chip, a GPS chip, a cellular radio, or any other suitable communication device. Further, communication device 60 may also function as a keyfob for access to restricted areas.

In operation of garment 2000, sensor 54 may detect an event, for example, a sudden increase in ambient moisture and/or temperature due to a significant steam leak proximate to safety garment 2000. Upon detection of the event by the sensor 54, the actuator 58 may, for example, deliver compressed gas to the deployable shield 56, and deploy the deployable shield 56 by inflation, which may provide protection to the head and neck of the wearer of safety garment 2000 by deflecting, blocking or shielding a portion of the steam, thereby potentially minimizing the risk of the steam injuring the wearer.

Referring now to FIGS. 5A and B, there is shown exemplary garment 3000 according to another aspect of the present disclosure. Garment 3000 may also possess one or more of the elements described above in respect of garment 10, garment 100, garment 200, garment 300, garment 1000 and/or garment 2000. Garment 3000 may comprise a covering 12, 14 configured to cover at least a portion of a wearer, the covering 12, 14 extending between and interconnecting a first location 64 and a second location 66 of the garment 3000, the second location 66 being spaced apart from the first location 64. The garment 3000 may comprise a flexible panel 16, the covering 12, 14 overlaying the flexible panel 16 and being attached to the covering at the first location 64 and the second location 64. The flexible panel 16 may, for example, comprise a liner covering at least a part of the torso or a limb of the wearer, and may, for example comprise a liner of substantially all of the covering 12,14.

The first flexible panel 16 may be attached to the covering 12, 14 using, for example, a bonding agent, for example a glue, or sewn to the covering 12, 14. The covering may comprise an excess material 68 between the first location 64 and the second location 66. The excess material 68 may, for example, be folded or rolled, or alternatively may comprise a folded knife-style pleat, or folded pleat. The excess material 68 may be configured to accommodate a stretching of the flexible panel 16 in a first direction, for example, when the wearer of safety garment 3000 moves, bends, sits, or proceeds to conduct an activity or task. The excess material 68, for example, by partially, substantially or fully unrolling, unfolding or extending in that first direction, may accommodate the stretching of the flexible panel 16 in the first direction, as shown in FIG. 5B, which, in part, shows covering 12, 14 in an expanded, unrolled or extended state relative to FIG. 5A due to stretching of flexible panel 16. The excess material 68 may be located at one or more locations on covering 12, 14, and may be located at areas where flexibility and/or comfort of the wearer may be preferred, for example, adjacent to joints of limbs of the wearer, adjacent to the waist of the wearer, or elsewhere.

In operation of garment 3000, wearer of garment 3000 will move or conduct any activity. In doing so, flexible panel 16 may stretch in a direction, extending or lengthening in that direction. The excess material 68 may extend, expand, unfold or unroll in that direction, as the case may be, accommodating the increased length, elongation or stretching of the flexible panel 16, and thereby facilitating and/or accommodating movement of the wearer. This may provide the wearer with flexibility or comfort when using garment 3000.

Aspects of garments 10, 100, 200, 3001000, 2000 and 3000 may be equally applicable to a non-safety garment, for example conventional or casual clothing such as shirts, jackets, coats or sweaters. For example, a garment may possess one or more of the elements described above in respect of safety garment 10, safety garment 100, safety garment 200, safety garment 300, safety garment 1000, safety garment 2000 and/or safety garment 3000, however, may comprise conventional fabrics and materials, and may be suitable in a wider range of applications. Alternatively, aspects of safety garments 100, 200, 3001000, 2000 or 3000 may be incorporated into conventional shirts, jackets, coats, sweaters, trousers or pants.

Safety garments 10, 100, 200, 300, 1000, 2000, 3000 may be adapted and configured for use with animals, for example canines, who may be exposed to dangerous or hazardous environments. For example, canine units used for police or tactical operations, explosives detection, or those used in rescue operations, would benefit as wearers of any one of safety garments 10, 100, 200, 300, 1000, 2000, 3000. Certain modifications for safety garments 10, 100, 200, 300, 1000, 2000, 3000 may be necessary for use with animals, for example sizing of coverings 12, 14, size and configuration of first and second flexible panels 16, 18, size and configuration of wearer-carrying harness 29, size and configuration of refillable heat pack 39, and size and configuration of deployable shield 56.

ADDITIONAL EMBODIMENTS

The additional embodiments described below and/or any features thereof may be combined or used in conjunction with the features described above in relation to safety garments 10, 100, 200, 300, 1000, 2000, 3000.

Referring to FIGS. 6 and 7, the present disclosure relates to a protective garment that may be in a form of a protective one-piece garment for covering the torso, the arms, and the legs of the user. The protective one-piece garment is preferably made of material that is waterproof, windproof, vapor or hot steam proof, or heat proof, or a material that has all these characteristics. The garment 120 includes a torso portion 22 for covering the user's torso and a pair of pants 124 for covering the user's legs. A waistband 26 delineates the torso portion 122 and the pants portion 124. A pair of arm sleeves 128 and 130 is attached to the torso portion 122 for covering the user's arms. The arm sleeves 128 and 130 are preferably long sleeves to cover the entire arm of the user. However, if desired, they may be short sleeves. The arm sleeves 128, 130 may be stretchable. The torso portion 122 includes several reflectors 132 positioned at several locations, such as on the arm sleeves 128 and 130, and the shin portions 134 of the pants. The reflector on the shin portions 134 extends all the way to the calf portions 135. At the back of the torso portion 140, diagonal reflectors 142 and 144 that cross each other are provided. The reflectors 132, 142, and 144 reflect light to allow the garment to be visible, especially at night. The torso portion 22 is stretchable relative to the bottom portion/leg portion 124.

Referring to FIG. 8, reflectors 132 are preferably also positioned on the left 36 and right sides 38 of the torso. The left side 136 and right side 138 are separated by a front zipper 146. The front zipper 146 can be unzipped to provide access and allow the user to wear the garment 120. The front zipper 146 starts from the neck area 148 past the waistband 150 and ends adjacent to the crotch area 152. The neck area 148 includes a collar 150. A pair of fasteners 152 and 154, such as hook and loop fasteners, is provided under the collar 150 to hold the collar in place when the collar is in a folded position.

Referring to FIGS. 9-10, the torso portion 122 includes an outer layer 160 has arm cutouts 156 and 158 at the area where the arms extend from the torso. Each sleeve 128 and 130 include a circular folded knife-style pleat 129 and 131, respectively. The circular folded knife-style pleat 129 and 131 insert through their respective arm cutouts 156 and 158. The front of the outer layer 162 is connected to a waistband 26 where the torso portion 122 ends and the pants portion 124 begins. The back of the outer layer 164 is not directly attached to the waistband 126 to provide flexibility to the garment 120, which is especially beneficial when the user bends over or leans forward.

Referring to FIGS. 11-12, the torso portion 122 includes an inner layer 166 positioned inside the garment 120. The inner layer 166 may be made of mesh material, or a combination of the mesh material and the same material as the outer layer 160. The inner layer 166 is preferably made of a 4-way stretch fabric so it can stretch in vertical and horizontal directions. The inner layer 166 attaches to the outer layer 160 around the neck area 150 at the highest point of the shoulder 151, the circular folded knife-style pleats 129 and 131, and the waistband 126. The circular folded knife-style pleats 129 and 131 are created by folding the material back upon itself and sewing the folded material preferably by fire resistant thread. Each of the circular folded knife-style pleats 129 and 131 starts at the highest point of the armhole and continues down the front chest of the coverall, under the armpit and back up the backside of the garment to connect with the highest point of the shoulder where the shoulder connects with the top sleeve. The circular folded knife-style pleat 129 or 131 is positioned around the arm cutout of the garment and it connects the respective sleeve 128 and 130 to the outer layer 160 of the garment 120. The circular folded knife-style pleats 129 and 131 unfold outwards as the tensile force directed along the fabric length causes the secondary panel to separate enabling the circular folded knife-style fabric pleat 129 and 131 to unfold as the wearers extend their arms in front or above them, across their chest, beside them, or behind their bodies while at the same time allowing the circular folded knife-style pleat to retract itself into its initial folded position. The stretchable mesh aids the pleats to extend 129 and 131 further and to retract into its initial folded position.

At the back of the garment 120, the inner layer portion 167 that attaches to the waistband 126 is preferably made of the same material as the outer layer 160 for durability. The inner layer portion 167 is preferably a waist fabric extension creating a single horizontally folded knife-style pleat so that such fold remains in its folded position as the wearer wears the coverall while standing in an upright, non-bent vertical position. The horizontally folded knife-style pleat unfolds as the wearer bends over at the waist towards the ground and retracts itself into its initial folded position as the wearer bends back up to his or her initial standing upright vertical position. The inner layer portion 167 attaches to the inner layer 166 that is a stretchable mesh liner internally attached to the upper fold of the single horizontally folded knife-style pleat that stretches to release the upper fold of the single horizontally folded knife-style pleat as the wearer bends over at the waist towards the ground. The inner layer 166 in the form of a mesh liner contracts and pulls the upper fold inwards and upwards as the wearer bends back up to his or her initial standing upright vertical position.

At the front of the garment 120, the inner layer 166 is preferably made entirely of the mesh material including the portion that attaches to the waistband 126. The inner layer 166 is separated by the zipper 146. The inner layer 160 attaches to the outer layer 160 the forms the left side and the right side of the garment 120.

Referring to FIGS. 13-14, the sleeves 128 and 130 are inserted into their respective arm cutouts 156 and 158 of the outer layer 160 and are attached to their respective circular folded knife-style pleats 129 and 131. The circular folded knife-style pleats 129 and 131 are attached to the inner layer 166. Since they are attached to the inner layer 166 and the inner layer 166 is stretchable, the sleeves 128 and 130 are stretchable and can extend and self-contract. Referring to FIG. 15, the back of the torso portion is also stretchable due to the outer layer 160 not directly attached to the waistband 126 and the stretchable inner layer 166 being directly attached to the horizontally folded knife-style pleat 167. The horizontally folded knife-style pleat 167 is attached to the waistband 126. When the user bends over, leans forward, or leans sideways, the inner layer 166 and the horizontally folded knife-style pleat 167 stretch and cooperate with the user's movements to provide comfort to the user.

Referring to FIGS. 16-17, the garment 120 preferably has adjustable bottoms 168 to accommodate a shoe. The bottoms 168 define a slit 170 that can be opened and closed via a zipper 172. The bottoms 168 further include a flap 174 positioned over the zipper 172 for covering the zipper 172. The flap 174 has fasteners 176 and 178, such as hook and loop fasteners, for opening and closing the flap 174.

Referring to FIGS. 18-25, the garment 120 includes several ergonomically positioned pockets such that they can easily be reached. For instance, a pocket 180 is provided on each side of the sleeve 128 and 130. A pair of pockets 182 and 184 are positioned the left side and the right side, respectively, of the front of the torso portion 122. Pockets 182 and 184 are preferably angled to allow a hand to easily reach inside them. The pants 124 have pockets by the hips (pockets 186 and 188). Pockets 186 and 188 may each have a divider 190 to separate the contents. The back portion of the pants has pockets 192 and 194 that are angled towards the hips to allow a user to reach in easily. Pockets 196 and 198 are also provided on each side of the leg adjacent to the knee. Pocket 196 and 198 are also slanted to make it easy for the user to reach inside them. The pockets are preferably sized large enough to accommodate a hand, and they have flaps to cover them. The flaps have fasteners to open and close the pockets. Some of the pockets may partially include the stretchable mesh material to increase their holding capacities. The pockets may include a 4-way mesh material to accommodate a flammable gas meter electronic device. The 4-way mesh allows the ambient air to enter the pocket via the holes of the mesh so the meter can read the saturation of the flammable gas in the ambient air. Some pockets may have partitions, such as partition 1100 for elongated pieces like pens and screwdrivers.

Referring to FIGS. 23-25, the garment 120 may adopt different color schemes. For instance, the reflectors may be of a first color, the pockets use a second color, the sleeves use a third color, and the rest use a fourth color. The torso portion and the pants portion may differ in color. The flaps of the pockets may differ in color with the actual pockets. The flaps of the bottom of the pants may have a color that matches the pockets and the collar. The garment may be customized with the desired color scheme.
