Abstract
In one aspect, an eye shield for a respirator mask of the type having a face piece adapted to fit over the face of a user is provided. The eye shield includes a visor assembly including a visor surrounded by a frame, the visor assembly configured to be removably mounted in an opening in the face piece. One or more fastener elements are provided on the frame for removably securing the visor assembly to the face piece. The visor is formed of a transparent material which filters electromagnetic energy emissions at one or more preselected wavelengths. In certain embodiments, one or more head up display assemblies are attached to the visor assembly for projecting a human viewable image to the visor.
Core Innovation
An eye shield for a respirator mask is provided with a visor assembly including a visor surrounded by a frame, where the visor assembly is removably mounted in an opening in a face piece. The frame includes a sealing surface that sealingly engages a surface on the face piece when the eye shield is attached, and one or more fastener elements removably secure the visor assembly to the face piece. The visor is formed of a transparent material that filters electromagnetic energy emissions at one or more preselected wavelengths.
At least one head up display assembly is attached to the visor assembly and disposed on an exterior facing side of the eye shield for projecting a human viewable image to the visor. The head up display assembly includes one or more manually actuable input devices disposed on a housing of the head up display assembly, where the manually actuable input devices control operation of the head up display assembly.
A breathing apparatus is also described that includes a face piece adapted to fit over a face of a user, and an eye shield having the removably mounted visor assembly with the sealing surface and fastener elements. The transparent visor filters electromagnetic energy emissions at one or more preselected wavelengths, and the at least one head up display assembly is attached to the visor assembly on an exterior facing side to project a human viewable image to the visor. The head up display assembly includes manually actuable input devices disposed on the housing to control operation.
Claims Coverage
The document provides three independent claims, with inventive features centered on a removably mounted transparent visor that seals to a respirator face piece and an exterior head up display projecting a human viewable image, controlled by manually actuable input devices. The coverage further includes interchangeable wavelength-specific visors and a breathing apparatus configuration.
Removably mounted transparent wavelength-filtering visor with sealing and fasteners
A visor assembly including a visor surrounded by a frame removably mounted in an opening in the face piece, a sealing surface on the frame sealingly engaging a surface on the face piece when attached, one or more fastener elements on the frame removably securing the visor assembly to the face piece, and the visor formed of a transparent material which filters electromagnetic energy emissions at one or more preselected wavelengths.
Exterior head up display projecting a human viewable image to the visor
At least one head up display assembly attached to the visor assembly and disposed on an exterior facing side of the eyeshield for projecting a human viewable image to the visor.
Manually actuable input devices controlling operation of the head up display
The at least one head up display assembly includes one or more manually actuable input devices disposed on a housing of the at least one head up display assembly, where the one or more manually actuable input devices control operation of the at least one head up display assembly.
Interchangeable attachable/detachable eye shield kit with different wavelength-filtering visors
A kit comprising a plurality of eye shields interchangeably attachable to and detachable from a respirator mask, including at least a first eye shield and a second eye shield, where each eye shield has a removably mounted visor assembly with a frame sealingly engageable via the face piece and one or more fastener elements for removably securing the visor assembly, and where the first visor filters electromagnetic energy emissions at a first wavelength and the second visor filters electromagnetic energy emissions at a second wavelength.
Breathing apparatus with removably mounted sealed eye shield and exterior head up display
A breathing apparatus comprising a face piece adapted to fit over a face of a user; an eye shield including a visor assembly removably mounted in an opening in the face piece; a sealing surface on the frame sealingly engaging a surface on the face piece when the eye shield is attached; one or more fastener elements on the frame removably securing the visor assembly to the face piece; the visor formed of a transparent material filtering electromagnetic energy emissions at one or more preselected wavelengths; and at least one head up display assembly attached to the visor assembly and disposed on an exterior facing side of the eyeshield for projecting a human viewable image to the visor.
Manually actuable input devices on the head up display for controlling operation in the breathing apparatus
In the breathing apparatus, the at least one head up display assembly includes one or more manually actuable input devices disposed on a housing of the at least one head up display assembly, where the one or more manually actuable input devices control operation of the at least one head up display assembly.
Overall claim coverage centers on a sealed, removably mounted transparent visor that filters electromagnetic energy emissions at one or more preselected wavelengths, an exterior-facing head up display assembly projecting a human viewable image to the visor, and manually actuable input devices disposed on the head up display housing for controlling operation. Additional coverage includes an interchangeable kit with multiple wavelength-specific visors and a breathing apparatus configuration.
