The present invention generally relates a welder's glove. More particularly, the present invention relates to a multi-purpose welder's glove. Most particularly, the present invention relates to a glove constructed of fire retardant or heat resistant material suitable for welding, and having elements formed on and projecting outward from the outer surface of glove to protect the user from impacts or other injury causing events.
The invention generally provides a welder's glove including a back side and a palm side constructed from a thermal-resistant material and defining a cavity therebetween including finger portions, a thumb portion, and a palm portion; at least one element on the back side and extending outward from the back side, the element being constructed of a protective material; and at least one pad formed on the palm side and covering a portion thereof, the pad being constructed of a thermal-resistant high grip material.
The invention further provides a welder's glove including a back side and a palm side defining a cavity therebetween including finger portions, a thumb portion, and a palm portion, wherein the back side and palm side are constructed of a thermal resistant material; at least one element on the back side and extending outward from the back side, the element being constructed of a protective material; and a pad area covering the tips of each of the finger portions having an inner layer constructed of a thermal resistant material and an outer layer constructed of a high grip material
The invention also provides a welder's glove including a back side and a palm side constructed from a thermal-resistant material and defining a cavity therebetween including finger portions, a thumb portion, and a palm portion; at least one element on the back side and extending outward from the back side, the element being constructed of a protective material; and at least one pad formed on the palm side and covering a portion thereof, the pad being constructed of a thermal-resistant high grip material; and a cuff extending from the palm side and the back side of the glove in a direction opposite the finger portions to define an opening, the cuff being constructed of a flame retardant material, the cuff including a flap and an adjustable fastener, adapted to attach the cuff in plural attachment points to adjust a circumference of the opening.
A welder working on a rig often needs to assist the crane operator when positioning materials on the rig. At these times, a typical welding glove will not protect a welder's hands from impact injuries common during rigging operations. Hairline fractures, bruising blows, and pinched fingers are common injuries found when performing rigging operations, for example when lowering bundles of structural angle, large plate, and sub-assemblies, or handling chains and cables. When assisting the crane operator, the welders will often carry a separate pair of rigging gloves to protect their hands. Since rigging gloves are not constructed with the high temperature conditions involved in welding in mind, the welder must carry two types of gloves. This is not an ideal solution since the welder may not always have both types of gloves when asked to help the crane operator resulting in a delay to allow the welder to get the appropriate gloves or in an injury, if the welder assists the crane operator without appropriate protective gloves. Therefore, a need exists for a welding glove that provides protection to allow the welder to use the same glove during welding and rigging operations.
A glove according to the concepts of the present invention is shown in the accompanying drawings. Glove 10 may be tight fitting yet flexible to provide manual dexterity needed when gripping chains and other metal parts during rigging operations. Glove 10 generally includes an outer surface 12 that is exposed and an inner surface 14 that defines a cavity 15 (
The glove 10 may be formed in a unified manner or constructed of individual sections that are joined together. For example, back side 16 and palm side 18 may be separate pieces that are sewn together to define cavity 15. In the example shown, back side 16 and palm side 18 are sewn together with stitching located within cavity 15 to form an internally seamed glove. An external seam is also suitable. A notch 20 (
To make it suitable for welding, glove 10 is constructed of temperature resistant materials. In the example shown, the base layer 30 of glove 10 are constructed of light weight grain goatskin. It will be appreciated that different materials may be used on the back and palm sides 16, 18 of glove 10 (
According to another aspect of the invention, glove 10 includes a long cuff 25. The long cuff 25 extends beyond the carpal bones of the wrist to protect at least a portion of the user's forearm from welding sparks and high heat. The cuff 25 may be a continuous cuff defining an uninterrupted circumference C through which the user's hand is inserted. Alternatively, as shown, cuff 25 may be divided by one or more openings, where the divided portions are attached or closed over each other to cover the user's forearm.
For rigging purposes, a tight fit for the cuff is desirable so that it will not become pinched or entrapped. To that end, an adjustable fastener, generally indicated at 35, may be provided to allow the user to snug the cuff 25 against the forearm when performing rigging operations. For example, a flap or strap 34 may be provided on cuff 25 with a hook and loop fastener 36, like Velcro®, on opposing surfaces of flap 34 and cuff 25 to provide multiple attachment points that allow the user to adjust the circumference C (
To further ensure a tight fit, cuff 25 may be made of an elastic material or contain an elastic band. In the depicted example, cuff 25 is made from a flame retardant elastic material. In the example shown, notch 20 formed on a base 26 of glove is continued through cuff 25 to allow adjustment of the cuff opening to facilitate proper fitting of the glove to the user's forearm. In this example, cuff 25 is divided into two parts along a side of the glove 10. A flap 36 extends from a back side 16 of glove 10 and is sized to wrap over a portion of cuff 25 on a palm side 18 of glove 10. An adjustable fastener 35 in the form of a hook and loop fastener is provided on an interior side of flap 36 and an exterior side of the palm side of the cuff 25. In this way, cuff 25 and glove 10 may be opened along notch 20 to facilitate insertion of the user's hand and forearm. Then, flap 36 may be pulled tight to the forearm and fastened to cuff 25 to close notch 20 for a snug fit.
Attachment of cuff 25 to glove 10 may be made according to any known method including stitching as shown. To provide suitable durability and flame retardant properties, a flame retardant thread may be used including, for example, Nomex® or Kevlar® thread.
According to another aspect of the invention, best seen in
The material for the pad areas 40 may be selected to improve the welder's ability to grip materials and provide heat resistance. The pad areas 40 may be constructed of one or more layers of material or coatings to perform these dual functions. For example, as best shown in
Pad areas 40 may be constructed in various shapes and separated by unpadded areas 55 that correspond to the jointed portion of the hand to facilitate articulation of glove 10. In the example shown, pads 46 are provided at tips 45 of fingers 28 that cover the distal and intermediate phalanges. It will be appreciated that separate pads might be provided for each of the phalanges. Also, in the depicted example, a single thumb pad 56 extends the entire length of thumb 50, which likewise could be divided into multiple pads based on the anatomy of the user's thumb. On the palm 52 of glove 10, a row of padding , generally indicated at 60, is provided over the joint between the proximal phalanges and the metacarpals, which forms the upper portion of the palm 52. The row 60 includes an index pad 61 at the base of the index finger of glove 10 and a minor finger pad 62 that spans the remaining fingers 28 of glove 10. It will be appreciated that the pad row 60 might be further divided into individual pads corresponding to one or more of the fingers 28.
Below this row 60, a thumb-base pad 65 is applied to the palm at the base of the thumb 50, and a heel pad 66 covers the remaining portion of the palm 52 inward of the base of the thumb 50 and below the row of pads 60 covering the joint at the base of the fingers 28. The shapes of the padded areas are arbitrary and chosen for ornamental purposes
According to another aspect of the invention, best seen in
Elements 70 may be formed along the back side of the fingers 28, the knuckle portion 72 of glove, and/or the base portion 74 of glove 10 covering metacarpal bones of the hand to provide impact resistance or to help resist crushing/pinching forces. The elements 70 may be constructed of various impact resistive materials including high impact polymer(plastic and rubber materials), thermoplastic resin (TPR), impact hardening polymers, such as Zoombang®, wood, metal, composites, or similar materials that absorb or deflect contact to protect the user's hand. To make the elements 70 suitable in welding applications, the materials may be selected to have high temperature resistance. While, as shown, ribs 76 may be used along the fingers 28 and thumb 50 (collectively the digit portions of glove 10) because their elongate shape facilitates flexing of the digit portions, boss elements may also be used on the fingers with gaps or thinner material at the finger joints to provide similar flexibility in the fingers. The shapes of the elements shown are arbitrary and chosen for ornamental purposes.
In the example shown, finger bosses 78 are provided at the base of ribs 76 to form a combined boss and rib element 70. Additional bosses 80 are provided over the knuckle portion 72 of glove 10. As shown, bosses 80 may be connected to each other by web portions 82 constructed of a thinner layer of material that provides protection yet is more flexible than bosses 80 to allow greater relative flexibility. In the example shown, an additional boss 84 cover the base portion 74 of glove 10. Since less flexibility is needed in this portion of glove 10, boss 84 may be formed as a unitary member.
