Abstract
A face mask comprises a mask body having apertures; an exhalation valve positioned within one of the apertures of the mask body; a harness assembly configured to extend about the wearer's head wherein the harness assembly; a first strap attached to the harness assembly, a strap retainer positioned on the mask body and disposed over the exhalation valve, the strap retainer configured to receive the first strap; and a valve protector. The first strap has front and rear surfaces, the front and rear surfaces defining a second thickness therebetween. The valve protector is positioned between the first strap and the exhalation valve and has a first surface configured to engage the exhalation valve and a second surface, opposite the first surface. The first and second surfaces define a first thickness therebetween such that a spacing between the first strap and the strap retainer controls the friction between the first strap and the front surface of the strap retainer.
Claims (11)
1. A face mask configured to be worn on a wearerâ s head and to cover the wearerâ s nose and mouth, the face mask comprising: a mask body having a plurality of apertures; an exhalation valve positioned within one of the plurality of apertures of the mask body; a harness assembly configured to extend about the wearer's head wherein the harness assembly; a first strap attached to the harness assembly, the first strap having a front surface and a rear surface, opposite the front surface, the front surface and the rear surface defining a second thickness therebetween; a strap retainer positioned on the mask body and disposed over the exhalation valve, the strap retainer configured to receive the first strap; and a valve protector positioned between the first strap and the exhalation valve, the valve protector having a first surface configured to engage the exhalation valve and a second surface, opposite the first surface, the first surface and the second surface defining a first thickness therebetween such that a spacing between the first strap and the strap retainer is configured to control the friction between the first strap and the front surface of the strap retainer.
2. The face mask of claim 1 wherein the spacing between the first strap and the exhalation valve is substantially the same as the second thickness of the first strap.
3. The face mask of claim 1 wherein one of the front surface and the rear surface of the first strap engages one of the first surface and the second surface of the exhalation valve.
4. The face mask of claim 1 wherein the front surface of the first strap engages the first surface of the exhalation valve and the rear surface of the first strap engages the second surface of the exhalation valve.
5. The face mask of claim 1 further comprising a second strap and wherein the strap retainer is configured to guide the first strap and the second strap in a crossed configuration, the first strap and second strap crossing at the valve protector, wherein the first strap and the second strap contact the valve protector.
6. The face mask of claim 1 wherein the harness assembly is adapted for retaining the mask body at a first position covering a wearer's nose and mouth, and at a second position dropped down from a wearer's face without removing the harness assembly from a wearer's head.
7. The face mask of claim 1 wherein the spacing between the outer surface of the valve protector and the inner surface of the strap retainer is substantially that of the thickness of the crossed straps.
8. The face mask of claim 1 wherein the valve protector is ring-shaped.
9. The face mask of claim 1 wherein the second surface of the valve protector includes at least one region underlying the first strap, the at least one region defining a region of friction.
10. The face mask of claim 9 wherein the second surface of the valve protector includes protuberances in the at least one region of friction.
11. The face mask of claim 1 wherein the valve protector includes an upper semicircular region and a lower semicircular region, the upper semicircular region of the valve protector having a dome shape.
