Definitions
- a welders mask for use with a respirator includes an eye protecting window mounted on an integral face covering section which is provided with an enlarged depending bubble portion adapted to enable a welder to wear a respirator during welding operations while still assuring sufficient ventilation for the welder.
- the face covering portion of the welders mask is provided with two side sections which extend rearwardly from the front of the mask for a distance sufficient to cover a welders ears.
- Thebubble portion of the mask is designed to be of sufficient volume such that when the mask is worn with a conventional respirator, at least two-thirds of exhaled air is expelled from the bubble volume thereby mixing with fresh air and, due to the chimney effect created by contact of warmer expelled air with fresh air, the latter is drawn upwardly and may be readily inhaled by the welder.
- expelling the aforementioned fraction of exhaled air from the bubble volume excessive, deleterious concentrations of carbon dioxide are inhibited from building up in the immediate vicinity of the respirator.
- This invention relates to a welders mask and more particularly, to a welders mask which may be worn with a conventional respirator device.
- welders In order to provide adequate protection to a welder from heat, radiation, dust, fumes and sparks, etc. generated during welding operations, it has been common practice for welders to wear a protective mask or shield. Various forms of eye protecting windows with appropriate radiation shielding or filter devices are also standard elements of a welders mask.
- One longstanding problem with welders masks has been the difticulty in assuring adequate ventilation for the welder in order to avoid the deleterious effects caused by breathing of various contaminants, and yet assuring a sufficient supply of fresh air for breathing.
- a welders mask for use with a respirator includes an eye protecting window and an integral face covering section having side portions which extend rearwardly and a lower depending bubble portion of sufficient size to substantially encompass a respirator device.
- the bubble portion extends frontally from the wearers chin for a distance of at least 7.5 cm. thereby defining a bubble volume of at least 500 ml. such that upon normal breathing by a welder, at least two-thirds of the exhaled air is expelled from the bubble volume.
- FIG. 1 is an isometric view of the front and side of an exemplary embodiment of a welders mask provided in accordance with the present invention.
- FIG. 2 is a further isometric view of the rear portions and head harness of an exemplary embodiment of a welders mask provided in accordance with the present invention.
- welders mask 10 generally comprised of side portion 11, bubble portion 12 and eye protecting window 13.
- welders mask 10 is preferably comprised of a suitable plastic material or the like sufficient to withstand heat generated during a typical welding operation. Although other than plastic materials may be utilized, it is preferred to form mask 10 from as light a material as readily and economically possible.
- mask 10 is herein described as intended for use by a welder,
- mask is suitable for protection against the aforementioned effects of heat, radiation, etc. regardless of the particular operation performed by the wearer.
- Side portions 11 of mask 10 are preferably substantially planar and extend from the frontal portion of mask 10 rearwardly for a distance sufficient to provide a covering of the ears of a welder.
- Bubble portion 12 is preferably configured in a substantially curvilinear fashion and is provided as a lower depending frontal and side portion of mask 10. The size of bubble l2 and the interior volume defined thereby is preferably sufficient to encompass and substantially surround a typical respirator (not shown) device worn by a welder during welding operations.
- the bubble portion is spaced sufficiently away from the welders face and respirator to permit the expulsion of exhaled air from the bubble volume and the introduction of fresh air such that adequate ventilation for a welder may be effected.
- a respirator is provided with various filters and valves which although permitting the flow of relatively fresh or pure air therethrough also have a restrictive effect upon breathing by a welder or other individual.
- filters and valves which although permitting the flow of relatively fresh or pure air therethrough also have a restrictive effect upon breathing by a welder or other individual.
- a welders mask must accommodate use of a respirator while simultaneously providing protection to the welder from heat, radiation or the like.
- the residual volume of CO in the human lungs is relatively insignificant with respect to the tidal volume of air (volume of air per breath). Therefore, it is clear that in order to avoid significant impairment of breathing efforts, no addi- ,tional CO should be added, by inhalation, to the aforementioned residual carbon dioxide.
- a respirator by any individual has, in general, been found to increase residual CO as the air contained within the respirator cavity at the completion of exhalation usually exhibits a higher than normal CO /O ratio. This air is then re-inhaled ahead of fresh air drawn through filters of the respirator. Subsequent covering of the face and a respirator with a device such as a mask or the like that does not have sufficient ventilation will only generate a C0 enriched atmosphere in the vicinity of the respirator which in turn still further impedes normal breathing efforts.
- a welders mask is provided with a lower depending bubble portion of sufficient volume to permit adequate ventilation, e.g.
- the welders mask By configuring the welders mask to be of sufficient size to enable adequate ventilation but yet of a size such that the major portion of CO rich exhaled air is expelled from the bubble volume, the problems of supplying fresh air while avoiding CO buildup of exhaled air are effectively solved by the welders mask provided in accordance with the teachings of the present invention.
- bubble portion 12 of helmet 10 is configured to define a volume of at least 500 ml. and preferably of approximately 700 ml., which for a typical respirator occupying a volume of 200 ml. will provide an effective air volume of 500 ml. within bubble portion 12.
- bubble portion 12 of mask 10 it is preferred to provide the frontal surface of bubble portion 12, i.e., that surface immediately below window 13, at a distance of at least 7.5 cm. from the normal location of a welders chin thereby assuring sufficient clearance between a respirator worn by a welder and the frontal section of bubble portion 12.
- a bubble portion 12 with mask 10 achieves the dual objectives of providing a supply of fresh air to a respirator worn by a welder or the like as well as avoiding the accumulation of CO rich exhaled air in the immediate vicinity of the respirator.
- Adjustment means 15 may comprise a conventional threadedly adjustable positioning device operated by means of a handle or knob as well known to those skilled in the art. Head harness 14 is more fully illustrated in FIG. 2, to which attention is now directed.
- head harness 14 may be adjustably and securely fitted to the head of a welder with the mask portion maintained out of contact from the welders head thereby avoiding any problems such as skin irritation which may be caused from contact with welders mask 10.
- head harness 14 and band 18 may be comprised of a-flexible plastic material.
- a welders mask adapted to be worn with a respirator and comprising an eye-protectingwindow and an integral face covering section having side portions which extend rearwardly from a frontal portion and a lower, depending bubble portion of sufficient size to encompass a welders respirator, which bubble portion is spaced frontally from the welders chin by at least 7.5 cm. thereby defining a bubble volume greater than 500 ml. such that upon breathing by a welder of 1.61 liters of air/min. at least two-thirds of the exhaled air is expelled from the bubble volume to thereby provide suffcient ventilation and to inhibit deleterious accreations of CO in both the respirator and in the immediate vicinity of the welders face.
- a welders mask as defined in claim 1 additionally comprising head harness means for supporting said face covering section in a position spaced away from the welders head. 5
