FIELD OF THE INVENTIONThe present invention relates generally to protective gloves, and more specifically, to protective gloves suitable for use in firefighting activities.
BACKGROUNDTraditional protective gloves for firefighters are constructed primarily of leather. While leather is a tough and durable material, it suffers from distinct drawbacks in the firefighting setting. Firefighters subject their equipment to harsh environments, including high heat, open flames, impacts, and water. Traditional firefighting gloves lose their efficacy and wear out quickly under the harsh conditions they are subject to by firefighters. For example, many gloves have a lifetime of less than three months before replacement is required. In addition, the leather of traditional gloves may expand and become slippery when wet, making it more difficult for a firefighter to retain a strong grip. When leather has been wet and then dried, it frequently becomes brittle and stiff. Further, the dark colors of traditional gloves may make it difficult for a firefighter and his or her team to see each other's hands in low light conditions. Traditional firefighting gloves also do not include significant impact protection or cut protection. These and other drawbacks are addressed by the embodiments of the invention consistent with the present disclosure.
SUMMARYA glove according to some embodiments may be configured for protection of a wearer's hand. The glove may include a glove body having a proximal end and a distal end including a dorsal portion, a cuff portion, a palm portion, a thumb portion having a dorsal side and a palmar side, and finger portions each having a dorsal side, a palmar side, and a forchette, an inner liner including an interior liner and a waterproof membrane, reflective striping secured to finger portions of the outer shell, and a thumb-seam between the thumb portion and the palm portion, the seam having a curved length extending from a base of the thumb portion towards the finger portions, an apex portion describing an acute angle pointed at the finger portions, and a return length extending away from the finger portions, wherein the thumb-seam is configured to permit the inner layer of the glove body palm portion to lie flat against a palm of the wearer's hand when a thumb of the wearer's hand is rotated through a range of motion. At least one of the finger portions and thumb portion may include impact disbursement ridges on the dorsal side thereof, the impact disbursement ridges being elongated structures extending away from the dorsal side and configured to flex under impact.
The invention relates generally to protective gloves. More specifically, this disclosure describes protective gloves suitable for use by a firefighter. Gloves consistent with the present disclosure may be fire retardant, impact resistant, water resistant, cut resistant, and otherwise strengthened and/or modified to protect the hands of a wearer from the rigors and dangers encountered during firefighting activities. Gloves consistent with the present disclosure may further include features to increase the dexterity and grip of a wearer with respect to conventional gloves. Gloves consistent with the present disclosure may further include aspects to enhance ease of use.
Glove body 200 has a proximal end 290 closer to the arm of the wearer when the glove 250 is properly worn and a distal end 280 further from the arm of the wearer when the glove 250 is properly worn. Glove body 200 may include a cuff portion 217, dorsal portion 215, and finger portions 205. Finger portions 205 may include an index finger portion 204, a middle finger portion 203, a ring finger portion 202, and a pinky finger portion 201. Each finger portion 205 may include a dorsal side 207, a palmar side 225 (not shown in
Interior liner 301 may form an innermost layer of glove 250, and, therefore, may directly contact hand 100 of the wearer. Interior liner 301 may be made from a material chosen to have favorable characteristics under conditions in which the hand 100 of the wearer is sweating. For example, interior liner 301 may include a moisture absorbent material or a moisture wicking material. These features serve to keep the hand 100 of a wearer comfortable during use. Interior liner 301 may include a material that does not stick to the skin when the skin sweats. This feature permits a wearer's hand to be easily removed from glove 250 and prevents inner liner 300 from pulling out of glove body 200 when the glove 250 is removed from hand 100. In some conventional protective gloves, an inner liner may stick to a sweaty wearer's hand and pull out of the glove when the hand is removed. Returning the liner to its original position can be a difficult and time-consuming task, creating a dangerous situation for a firefighter that must work quickly. In some embodiments, inner liner 300 may include a Kevlar knit material.
Membrane 302 may include a water-resistant or waterproof material. In some embodiments, membrane 302 may further include a breathable waterproof material. Breathable waterproof materials permit the passage of water vapor while denying the passage of liquid water. Such materials permit sweat to exit the glove vaporous form while preventing liquid water from reaching a hand 100 of the wearer. Breathability in the membrane allows a wearer's hands 100 to remain comfortable inside the gloves when they start to sweat. The water resistant or waterproof aspects of the membrane 302 promote comfort for the user and also reduce the possibility of heat conduction through a wet material, because wet materials more readily conduct heat. Membrane 302 may include a multilayer microporous material. The multiple layers of such a multilayer material may include a first layer with pores small enough to prevent the passage of water, for example, less than half a micron in diameter. A second layer may include moisture absorbing layer to absorb moisture for slow release through the pores of the first layer. The second layer may have a honeycomb structure to facilitate moisture absorption. A third layer may include an additional dense layer for added protection against water incursion and located for skin contact. Exemplary multilayer microporous materials include Hipora. Membrane 302 may include any other waterproof and breathable material, such as Gore-Tex and others.
Interior liner 301 and membrane 302 may be joined at a cuff region 307 by cuff 303. Cuff 303 may be joined to both interior liner 301 and membrane 302. When liner 300 is inserted into glove body 200, cuff 303 may further be attached to liner 300.
The foregoing description of the inner liner includes a non-limiting description of exemplary materials and their properties. Other materials exhibiting similar properties may be employed without departing from the scope of this disclosure.
Impact disbursement ridge structure 401 may include an impact ridge base 402, at least one impact disbursement ridge 209, and at least one impact disbursement end cap 403. Impact ridge base 402 may be an elongated structure extending along at least a portion of a length of a finger portion 205 or thumb portion 255. Impact disbursement ridge structure 401 may include as many as twenty or more impact disbursement ridges 209. In a particular embodiment, impact disbursement ridge structure 401 may include between seven and fifteen impact disbursement ridges 209. In some embodiments, a number of impact disbursement ridges 209 may be determined by a length of a finger portion 205 or thumb portion 255 that is protected by impact disbursement ridge structure 401. Impact ridge base 402 may include a flexible material, such as a thermoplastic elastomer (TPE) or thermoplastic rubber (TPR), and may be flexible so as to permit the finger portions 205 and thumb portions 255 to bend and flex with relative ease. Impact disbursement ridges 209 may also include a flexible material, such as TPE or TPR. In some embodiments, the various aspects of each impact ridge structure 401 may be molded as a single piece.
Impact disbursement ridges 209 may be elongated structures extending away from impact ridge base 402. Impact disbursement ridges may include a height 410 and depth 412, as illustrated in
The structure and material of impact disbursement ridges 209 provide several functional advantages over conventional protective gloves, particularly for those used in the dangerous environments that firefighters may encounter. Dangers encountered by a firefighter may include high heat as well as frequent risk of impact from debris, tools, and structures. Impact disbursement ridges 209 are each connected to impact ridge base 402 along a relatively narrow depth 412. As illustrated in
The fin-like structure of impact disbursement ridges 209 also provides additional impact protection. When the dorsal sides of the finger portions 205 are subject to an impact, impact disbursement ridges 209 serve to dissipate the energy of the impact before it reaches the hands 100 of the glove wearer. A solid impact protection structure may absorb some energy as the material itself compresses, but after the material has compressed, remaining energy may be transmitted to the hands 100 of the wearer, potentially resulting in injury. In contrast, the ridged design of impact ridge structure 401 may dissipate additional energy as impact disbursement ridges 209 bend and buckle as a result of impact. Thus, impact ridge structure 401 may dissipate impact energy not only through material compression, but through structural deformation. This feature grants additional impact protection to the hands 100 of a glove wearer.
Impact disbursement ridges 209 may comprise a TPE or TPR material. Conventional materials used in protective gloves for impact protection may include, for example, rubbers. Conventional rubbers, under high heat conditions common in a firefighting situation, may easily scorch, burn, melt, and/or otherwise lose their integrity. Even if the rubber is not melted or burned, high heat may alter the properties of vulcanized rubber, making it unsuitable for reuse. In contrast, TPE and TPR materials exhibit thermoplastic behavior under high heat conditions, and are less prone to suffering integrity loss in firefighting situations.

Glove body 200 may further include impact absorbing pads 705 located between layers. In some embodiments, impact absorbing pads 705 may be located in dorsal portion 215 between the glove body outer layer 701 and the glove body inner layer 703. More particularly, impact absorbing pads 705 may be located between secondary inner layer 702 and outer layer 701. Impact absorbing pads 705 may be positioned so as to extend across the knuckles of a wearer's hand 100, as illustrated in
Inner layer 703 may include a breathable membrane. Such a breathable membrane material may include, for example, oxypan. A breathable membrane permits airflow to the inner liner 300, which serves to keep a wearer's hands 100 comfortable.
Outer layer 701 may include a cut resistant material such as aramid fibers, including meta aramid fibers such as Nomex and para aramid fibers such as Kevlar. In a particular embodiment, outer layer 701 in a cuff portion 217 may include a meta aramid fiber and an outer layer of dorsal portion 215, palm portion 220, thumb portion 255, and finger portions 205 may include a para aramid fiber. Aramid fibers, such as Kevlar and Nomex are extremely resistant to cutting and tearing, and when employed in glove body 200, serve to maintain the integrity of glove 250. Additionally, cut resistant outer layer 701 serves to protect the hands of the wearer against many hazards that might be encountered in a firefighting situation, such as wooden splinters, shattered glass, sheared metal, and others. Additional and different cut resistant materials may be employed for outer layer 701 without departing from the scope of this disclosure.
In some embodiments, dorsal portion 215 of the glove body 200 may further include a secondary inner layer 702 comprising an aramid fiber located between the outer layer 701 and the inner layer 703. Secondary inner layer 702 provides additional cut resistance to the areas of glove body 200 in which it is employed. Although illustrated in
In some embodiments, at least a portion of outer layer 701 may include a silicone coating 350, described in greater detail below. In some embodiments, a least a portion of outer layer 701 may include a waterproof breathable coating, for example, a coating of Hipora or Gore-Tex. A waterproof breathable coating may be employed in any area of glove body outer layer 701 where silicone coating 350 is not employed. The waterproof breathable coating over outer layer 701 provides significant advantages over conventional, non-waterproof gloves. Firefighters frequently work in a wet environment, as water is an important weapon against fire. Wet gloves, however, more readily conduct heat, decrease dexterity, and can become very uncomfortable and unwieldy. The waterproof coating over outer layer 701 serves to diminish or eliminate these disadvantages.
