ABSTRACT:
FIELD OF THE INVENTION
This invention relates to welding helmets.
BACKGROUND
Welding helmets generally have a smoothly shaped exterior based on their requisite function to protect the welder's head and neck from sparks. Welding helmets have a viewing device which protects the welder's eye from sparks and also provides protection from the damaging brightness of the welding.
Welding helmets are equipped to be able to rotate from an in-use position in front of the welder's face to an open position. The assemblies used for this in general are headgear which the welder wears on his head and which pivotally attach to the helmet. One type is made of straps fitting the welder's head and another fits on a hard hat worn by the welder. All welding helmets must pass the ANSI Z87.1 standard.
SUMMARY OF THE INVENTION
The invention is a welding helmet made of an appropriate plastic and molded in to the shape of a mammalian head. Particular implementation includes a human skull, a bulldog, and a gorilla. The mammalian head is designed to provide a bib portion to protect the neck and upper chest area and is designated to extend sufficiently to the rear to protect the side of the head and ears from sparks. Also it is shaped to enable the welder to wear a respirator.
