ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to welding equipment and, more specifically, to an illuminated lens device having a housing having a shaded lens therein having a plurality of spaced apart circumferentially positioned lights which can be selectively illuminated by a switch whereby the wearer of the illuminated lens device will be able to see through the normally dark lens.
Further, the illuminated lens device has a compartment for the placement therein of a power source, such as batteries. In addition, the electric circuit for the illuminated lens device has a timer switch incorporated therein, whereby the user can vary the duration of illumination.
The illuminated lens device of the present invention can be retrofitted to existing helmets or can be manufactured as an integral part of new helmets.

A lighting system for a welders helmet which includes a high intensity, high Kelvin temperature electric light source attached to the face shield for directing a high energy, high Kelvin temperature light beam forwardly of the viewing port, and an energizing circuit including an on-off switch interconnecting the light source to a source of electrical energy which deenergizes the light source where the welde's eyes are not protected by the face shield.

A portable light that is hands-free, out of the way, adjustable, and automatically directed to the user's line of sight by virtue of his head movement. This is accomplished by taking a topless hat, commonly known as the visor, and building around it to form a portable light that is worn on the head. Said visor would have battery casing molded at the base of the brim closest to the forehead to minimize the downward pull of the battery's weight. The bulb assembly housing unit is attached to the front of the brim by means to allow pivotal movement thus allowing for the light to he directed forward or downward, or at any angle in between.

A combination baseball style cap and light assembly, wherein the cap has a crown, a bill extending from the crown, a sweatband liner circumscribing the bottom edge of the cap, and a reinforcing crown liner, has a double light and switch assembly comprising two lamp sockets affixed to a mounting plate on each side of a sealed sub-mini micro switch also affixed to the mounting plate. The plate is in turn affixed to the underside of the bill of the cap, two lamp sockets affixed to the mounting plate such that their axes decline at an acute angle to the plane of the plate and converge at an acute angle to a line perpendicular to the front edge of the plate, setting the focal point of the lamps at a predetermined location directly out from and generally equidistant between the wearers eyes. A micro switch is affixed to an integral mounting flange on the mounting plate located approximately on the center line of the mounting plate between the two sockets. First and second battery holders are each affixed respectively to each side of the center line of the top edge of the reinforcing element of the crown of the cap and the top edge of the crown of the cap, and a circuit electrically couples the micro switch, the lamp sockets and the battery holders.

Issued: Sept. 14, 1999
A head mounted illumination device including a light source disposed within a housing. The light source includes a plurality of lights disposed within the housing. The housing is securable to a mouthpiece of a headset to facilitate securement of the light source to the headset. An activation button is disposed within the housing. The activation button is in communication with the light source. The activation button includes a contact switch extending outwardly of the housing. The contact switch aligns with a lip of a user. A power source is securable to the headset. The power source includes wiring extending outwardly therefrom. The wiring couples with the activation button to facilitate communication therewith.
While these headgear lighting devices may be suitable for the purposes for which they were designed, they would not be as suitable for the purposes of the present invention, as hereinafter described.
SUMMARY OF THE PRESENT INVENTION
The present invention discloses means to illuminate the lens of a face shield to be worn by a welder. The lens is illuminated to enable the welder to see through the lens prior to the welding arc being lighted. The face shield is equipped with a size adjustable head band. Multiple lights are disposed around the frame of the lens and an on/off switch is provided along with a time delay button. The lights are powered by a battery which is disposed in frame. The present invention can be retrofitted onto existing helmets or manufactured as an integral part of new helmets/face shields.
A primary object of the present invention is to provide an illuminated lens device for selectively seeing through a normally dark lens.
Another object of the present invention is to provide light for the welder to see by before the arc powered. Also to provide a light which mounts to an attachment shield around the viewing lens.
Yet another object of the present invention is to provide light for the welder to see by before the arc powered. Also to provide a light which mounts to an attachment shield around the viewing lens. A light which is directed toward the lens so that the welder can see the work before the arc is started.
Still yet another object of the present invention is to provide light for the welder to see by before the arc powered. Also to provide a light which mounts to an attachment shield around the viewing lens. A light which is directed toward the lens so that the welder can see the work before the arc is started. Lens light is controlled by a button on the face shield, the light has a timer which will allow the welder to turn the lens light on and get into position and is powered by batteries.
Yet another object of the present invention is to provide light for the welder to see by before the arc powered. Also to provide a light which mounts to an attachment shield around the viewing lens. A light which is directed toward the lens so that the welder can see the work before the arc is started. Lens light is controlled by a button on the face shield, the light has a timer which will allow the welder to turn the lens light on and get into position, and is powered by batteries. After a predetermined length of time, the welder should have started the arc and can see by that light.
Additional objects of the present invention will appear as the description proceeds.
The present invention overcomes the shortcomings of the prior art by providing light for the welder to see by before the arc powered. Also to provide a light which mounts to an attachment shield around the viewing lens. A light which is directed toward the lens so that the welder can see the work before the arc is started. Lens light is controlled by a button on the face shield, the light has a timer which will allow the welder to turn the lens light on and get into position, and is powered by batteries. After a predetermined length of time, the welder should have started the arc and can see by that light.
The foregoing and other objects and advantages will appear from the description to follow. In the description reference is made to the accompanying drawings, which form a
