[0039] Reference is now made to FIGS. 1-3, which show one type of welding hood, generally indicated as 1, in accordance with the prior art. The welding hood 1 comprises a face protective shield 2, having a forward or front side 3, that is convex in shape, and a rearward or back side 4 that is concave in shape and configured for receiving an operator's face, a top 8a and a bottom 8b. A viewing opening or window 5 is provided so as to enable the operator to see what is being welded. A strap 6 is provided for holding the hood about the operator's face. As can be seen from FIG. 2, the area or frame 5a surrounding the viewing opening 5 is either flush with or extends slightly inward with respect to the rearward side 4 of the shield 5. As shown in FIG. 3, the welding hood 1 includes side portions 7 that only partially cover the operator's ears. Also, as can be seen in FIGS. 1-3 the bottom 8b of the hood 1 or face shield 2, does not extend very far down, leaving a significant portion of the operator's neck exposed.

[0040] Reference is now made to FIGS. 4-19, which are directed to the welding hood, generally indicated as 10, for protecting an operator's face, as well as the operator's ears and neck, in accordance with the present disclosure. The welding hood 10 comprises a face protective shield 12 having a forward or front side 13, which is typically convex in shape, a rearward or back side 14, which is typically concave in shape, and configured for receiving the operator's face, a bottom portion 15, and a top portion 17. A viewing opening 16 extends through the face shield 12. The viewing opening 16 is located in a position in front of the eyes of the operator when the hood 10 is fixed to the operator's head. It can be appreciated that the opening 16 can have any shape, including, but not limited to, a square, rectangle, oval, a pair of circles, and the like. The welding hood 10 also includes an eye box 18, extending from the rearward or back side 14 of the hood 10, as shown in FIGS. 5, 11, and 13. The eye box 18 is located adjacent the viewing opening 16. It can also be appreciated that the eye box 18 can have any shape, including, but not limited to, a square, rectangle, oval, a pair of circles, and the like.

[0041] With continuing reference to FIGS. 5, 11, and 13, the eye box 18 has at least one wall 20 framing at least a portion of the viewing opening 16. The at least one wall 20 extends inwardly from the rearward side 14 of the shield. According to one embodiment, a plurality of walls 20 are provided for fully framing or completely surrounding the viewing opening 16 so as to block at least one of reflective arc flashes, sunlight, shop-lighting, and the like, from entering the operator's field of view during welding. The welding hood 10 also includes a lens 24 located within the viewing opening 16 for protecting the operator's eyes while allowing the operator to look through the viewing opening 16.

[0042] Still referring to FIGS. 5, 11, and 13, the walls 20 of the eye box 18 can be contoured to fit to the operator's face and surround the operator's eyes. In particular, the walls 20 can be contoured or can be formed from a flexible material, such as rubber or a foam material, so that the walls 20 fit flush against the operator's face to reduce the amount of sparks, dirt, debris and the like, from coming into contact with the operator's eyes. It can be appreciated that the walls 20 can be formed from an inflexible or rigid material, such as wood, plastic, or stiff rubber material, wherein the rigid material is shaped or contoured to fit an operator's face. It can also be appreciated that the walls 20 can be formed from a partially flexible material, such as a rubber material or a heat resistant foam rubber material, that is sufficiently flexible to conform to the operator's face, but rigid enough to provide blockage against arc flashes, light, sparks, dirt, debris, and the like.

[0043] The lens 24 can comprise a light-filtering lens for filtering light passing through the opening toward the rearward side 14 of the hood 10. The welding hood 10 can include a holding member 26 for removably holding the lens 24. The holding member 26 includes a pivoting portion 29 that is capable of pivoting via one or more pivot screws 28, between an open and closed position about the viewing opening 16. The provision of a pivoting holding member 26 enables the operator to lift the holding member 26 and lens 24 for better viewing of a fit-up or grind, if needed, or for communication with another person, without having to lift the protective shield 12 from their face. This provides an added safety measure to the welding hood 10. The holding member 26 can be configured for removably holding the lens 24 so that the lens can readily be removed and replaced with another light-filtering lens, whether for replacement due to damage or for replacement with a darker lens or with a clear lens.

[0044] As shown in FIGS. 5 and 13, at least one strap 30 is provided for securing the welding hood 10 to the operator's head. The at least one strap 30 can comprise an elastic strap that wraps around the operator's head. According to one embodiment, a pair of extending members 31a, such as bolts, screws, and the like, can be provided on opposing walls 20 of the eye box 18 and the strap 30 can be secured to the extending members 31a, such as with hooks 31b located at the ends of the strap 30. This arrangement enables easy attachment and removal of the strap 30 about the operator's head. It can be appreciated that the strap 30 can be secured to the eye box by other well-known means, such as rivets, screws, and the like. The strap 30 can also be secured to the face shield 12, itself, by known attachment arrangements. The elastic strap 30 can be adjustable, such as with a double band and a movable buckle or any other well-known means to adjust the strap, so as to securely hold the hood 10 in place for both safety and comfort. According to one embodiment, the strap 30 can be formed from an elastic material, similar in size and shape to a strap used in ski goggles or scuba masks. The strap 30 is designed to hold the hood 10 in place, regardless of the position and/or movement of the operator's head. It can be appreciated that the strap can be formed from other known materials and can have other known designs.

[0045] Referring now to FIGS. 6-9 and 14-17, the face protective shield 12 can include a first side portion 32 having a first width W1 configured for extending over at least a portion of or completely covering the ear of the operator and a second side portion 34 having a second width W2. According to the embodiment shown in FIGS. 3-11, the first width W1 can be substantially equal to the second width W2. This particular design provides added coverage to the operator's ears and/or sides of their face, especially when compared with the prior art design, as illustrated in FIGS. 1-3. Prior art welding hood designs, such as shown in FIGS. 1-3, typically have a standard width SW from the front of the lens holder back to the rear edge on the side of about 7-7 inches. As can be seen in FIG. 3, this design leaves a substantial portion of the operator's ear and/or face exposed. The welding hood of the present invention has at least one or both sides extended to a width W1 and W2 of approximately 8-9 inches, or 8 inches, from the front of the lens holder 26 back to the rear edge on the sides 32 and/or 34 so as to provide extra protection to the operator.

[0046] According to the embodiment shown in FIGS. 12-17, the second width W2 can be less than the first width W1, wherein the second width W2 is configured to enable air movement about the operator's face. This second width W2 can also be designed so as to leave a portion of the operator's ear uncovered so that the operator's hearing is not impaired.

[0047] It can be appreciated that the welding hood 12 can be molded so that the first and second widths W1 and W2 of the first side 32 and second side 34 are of equal width, but extended when compared with the prior art. The first and second sides 32, 34 can include scoring 36, as shown in FIG. 16, or the like, to facilitate removal of a portion of one or both sides 32, 34, as needed. Alternatively, the welding hood can be formed from a material that enables one to remove a portion of one or both sides 32, 34 so as to facilitate air flow under the welding hood 10 and uncover a portion of the operator's ear and/or face, as desired.

[0048] Referring back to FIGS. 1-3, the prior art hood 1 has a bottom portion 8b that extends from the bottom 9 of the viewing opening 5 for a length S1 of approximately 7 inches but curls under the chin, leaving a significant portion of the neck exposed, as shown in FIG. 3. In accordance with one embodiment of the present invention and with reference to FIGS. 8, 9, 16, and 17, the welding hood 10 can be designed to have a length L1 of rigid material of approximately 6 to 7 inches or approximately 6 inches, from the bottom 27 of the lens holding member 26, and, as shown in FIG. 18, a bottom attachment portion 45, such as leather or similar material, can be attached to the bottom portion 15 of the face shield 12 to provide additional protection of the operator's neck. This bottom attachment portion 45 can have a length L2 of approximately 2-3 inches, or 2 inches, and can be attached to the bottom portion 15 of the face shield 12 by any well-known means 46, such as snaps/rivets, hook and loop, auto tape, as the like, such that this bottom attachment portion drapes and/or flexes for further protection of the neck without curling under the chin. It can be appreciated that the flexible attachment portion 45 for the bottom of the face shield 12 can be formed from any well-known heat resistant material, such as leather, rubber, heat-resistant plastic, and the like. According to one example, the flexible bottom attachment portion 45 can be a three-by-twelve-inch suede split or similar material attached to the bottom portion 15 of the hood.

[0049] With reference to FIG. 19, according to one embodiment, the first or second side portion 32, 34 can comprise a removable side attachment portion that can be attached to either a right side or a left side of the face protective shield 12, depending upon whether the operator is right-handed or left-handed. This removable attachment portion 47 can be applied to either side 32, 34 of the face protective shield 12 of the welding hood 12 or it can be applied to both sides 32, 34, if desired. It can be appreciated that the removable attachment portion 47 can be added to the already extended side portion 32, 34 to provide extra protection, or can be added to a side portion that has not been extended to provide protection as needed. This removable attachment portion 47 enables customization of the welding hood 10 for the operator and provides the operator with additional protection closest to a welding area. The removable attachment portion 47 can be formed from a flexible material, such as any well-known heat resistant material, including but not limited to leather, rubber, suede, heat-resistant plastic, and the like and can be secured by any well-known securing means 48, such as snaps, hook and loop, and the like. The securing means 48 can be provided on both sides of the face protective shield 12 so that the attachment portion 47 can be secured to either side 32, 34 of the face shield 12, enabling customization of the welding hood 10, depending upon whether the operator is a right-handed or left-handed welder and/or to provide the operator with additional protection closest to a welding area.

[0050] As can be seen from the foregoing description and drawings, the welding hood of the present invention overcomes many of the deficiencies of the prior art by providing numerous safety features for the eyes, ears, and neck of the operator while also increasing the comfort to the operator. The welding hood can also be readily customized to meet a particular need of the operator and/or for use within a particular working environment.

[0051] While the disclosure has been described as having exemplary designs, the present disclosure can be further modified within the spirit and scope of this disclosure. This application is, therefore, intended to cover any variations, uses, or adaptations of the disclosure using its general principles. Further, this application is intended to cover such departures from the present disclosure as come within known or customary practice in the art to which this disclosure pertains and which fall within the limits of the appended claims.
