Definitions

  • the present invention relates to an ambidextrous and flexible working glove which is suitable for working with building materials or operating tools and ma chines.
  • the invention also relates to a hand mold for coating such gloves.
  • the working glove is knitted symmetrically on both sides of the broad surfaces of the glove, such that the glove is suitable for both hands of a person.
  • the glove further comprises bending zones on the parts of the fingers of the glove, covering the knuckles of a human hand, and is coated with a wear-reducing material, such as a polymer, on both sides of the glove, up to the wrist.
  • Working gloves are essential to craftsmen, such as masons carrying coarse building materials such as bricks, tool operators, and machine operators etc.
  • Working gloves provide several benefits, such as an improved grip on coarse or slippery materials and tools, and even protects the craftsmen’s and opera- tors’ hands against abrasive actions and low temperatures.
  • a wear-resistant material such as a pol- ymer
  • EP2487284 discloses a such glove.
  • the glove disclosed in the above mentioned EP document is only coated on one side of the glove, thereby rendering it unsuitable for being used on both hands, since the benefits of providing an improved grip, and resisting wear, only apply to one side of the glove, and since the glove thereby is more flexible on one side than on the other.
  • working gloves some times wear faster on one hand than on the other hand, e.g. when a worker uses his right hand more than his left hand. In such cases, the worker will have to pick up a new pair of working gloves, and leave the previous pair, even though only one of the two gloves is worn.
  • an ambidextrous working glove is desirable, being suitable to be put on both human hands, since the worker then only needs to pick up one new working glove, if one of the pair of working gloves he is using, becomes worn.
  • Ambidextrous gloves are known, such as in FR1203433.
  • the above mentioned ambidextrous glove is not suitable as a work ing glove, and would wear at a higher rate when working with coarse material, such as building material, than a working glove would.
  • a known hand mold for coating of a glove discloses a hand portion and a num ber of fingers.
  • the hand mold is provided with a mounting flange for connection to an arm or connection piece for connecting the hand mold to a machinery for moving one or more hand molds through a coating application area.
  • the coating is provided to the fingers and palm area of the glove.
  • This known hand mold is shaped like a right hand or a left hand having a convex shape on its upper side (back side of the hand) and a concave shape on the palm side of the hand.
  • the object of the present invention is inter alia to provide a working glove and a hand mold for manufacturing such a working glove that accommodates the above mentioned desired features.
  • a working glove which is ambidextrous, and thus suitable for both human hands, is coated by a wear resisting material on both sides, and comprises elastic areas covering the knuckles of the human fingers.
  • a knitted ambidextrous glove may be symmetric about a plane through the glove between the flat front side of the palm of the glove and the flat back side of the palm of the glove, wherein the glove may be knitted by a first material, wherein the knuckles of the glove covering the knuckles of a human hand, are knitted by a composition of the first material and a second material having a higher elasticity than the first material, or a composition of different materials, wherein the knuckles of the glove covering the knuckles of a human hand, are knitted by the composition of different ma terials comprising more of a material, having a higher elasticity, than a mate- rial, having the lowest elasticity, thereby defining a bending zone at the knuck les of the glove, wherein the fingers of the glove are coated by a coating ma terial, or the fingers and a part of the palm of the glove are coated by a coating material, or the glove up to
  • the working glove according to the invention is further beneficial, since the working glove, when one side is of it is worn, may be flipped and put on again, thereby making use of the other side of the working glove which is not worn, thereby contributing even more to the reduction of discarding unworn working gloves.
  • the term “knuckle(s)” refers to the joints of the human finger, joining the parts of the human finger.
  • the terms “fingers of the glove”, “the palm of the glove”, and “the knuckles of the glove”, refer to the parts of the working glove covering the fingers, the palm, and the knuckles of the human hand, respectively.
  • each finger of the glove may comprise multiple bending zones, wherein one, some, or all knuckles of each finger of the glove may be covered by at least one of the bending zones.
  • the working glove may be manufactured by providing a substrate, preferably a glove liner knitted of yarn, made of natural or synthetic fibres or a combina tion of natural or synthetic fibres.
  • the glove liner is knitted into a shape corre sponding to the hand, i.e. having fingers for each finger of the hand and an elastic cuff, with a width of e.g. 4 to 7 cm, which is knitted together with the remaining part of the glove liner in order to attaching the glove to the under arm near the wrist during use.
  • natural fibres are cotton, bamboo or mixtures thereof and examples of suitable synthetic fibres are e.g. of poly olefins, such as polyethylene (PE) or polypropylene (PP), polyester, i.e.
  • the fibres comprise minor amounts of a material which provides elastic properties to the glove liner, e.g. lycraTM or spandex, i.e. a polyurethane-polyurea copolymer, or similar elastic fibres commonly used as additional fibres for enhancing elasticity of fabrics, e.g. knitted fabrics.
  • a material which provides elastic properties to the glove liner e.g. lycraTM or spandex, i.e. a polyurethane-polyurea copolymer, or similar elastic fibres commonly used as additional fibres for enhancing elasticity of fabrics, e.g. knitted fabrics.
  • the bending zones are knitted in the same material as the rest of the knitted glove, but with a higher content of the material in the composition, having a higher elasticity, than the material in the composition, having the lowest elas ticity.
  • the coating material may be a polymer material.
  • polymeric coatings are e.g. natural latex, polyurethane (PU), pol yvinyl chloride (PVC), nitrile butadiene rubber (nitrile rubber or NBR), neoprene (polychloroprene) polyvinylacetate (PVA) or mixtures thereof, in particular mix tures of nitrile rubber and PU.

  • PVA polyvinylacetate
  • two or more layers of different poly meric coatings may be applied on top of each other.
  • an inner PU layer and an outer layer of nitrile rubber may provide a waterproof protec tive coating.
  • the polymeric material may be applied to the knitted glove as an aerated or foamed composition, which results in reduced use or elimination of use of or ganic solvents thereby providing a more environmental friendly protective glove which also provides reduced health risk for the user of the glove because it does not contain residues of an organic solvent.

  • the coating is a protective coating resisting wear on the working glove, espe cially in the finger and palm area.
  • Such coatings may be provided by mounting the glove on a hand-shaped mould and dipping the knitted glove into a liquid polymeric composition to ensure that the coating covers the relevant area of the glove as discussed above. If necessary, the dipped glove is cured.
