Patent number: 6536435Abstract: A quick release mechanism and headpiece for use with a respirator. The quick release mechanism uses a cam latch pivotably attached to a yoke to control the tension in an upper tension strap. In the latched position the upper tension strap traverses the yoke and, together with a pair of lower tension straps and neck catch, support and seal the respirator mask against the face of the wearer. In the unlatched position the upper tension straps loosely support the mask below the chin of the wearer in a parked position. The upper strap is attached to a circular shaped headpiece having a crown piece fitting to the top of the head of the wearer. The lower straps are attached to a rounded neck catch secured behind the neck of the wearer. The upper and lower straps preferably and advantageously comprise a material or materials having a low maximum elongation to ensure a snug and comfortable mask fit.Type: GrantFiled: June 30, 2000Date of Patent: March 25, 2003Assignee: Cabot Safety Intermediate CorporationInventors: Keith E.

Patent number: 6511177Abstract: Safety eyewear is presented which is provided with particulate sealing around the inside periphery of the lens/lenses and having temples that provide adjustment of the eyewear to a pantoscopic angle. The eyewear is provided with an adjustable strap assembly for better fit to the wearer's head. The eyewear lens/frame includes a plurality of projections that define various pantoscopic angles. The temple end piece includes a set of recesses that engage the projections formed on the lens/frame which temple end piece is rotated relative to the lens/frame to set the pantoscopic angle. The adjustable strap assembly further adjust the fit of the eyewear and can be unbuckled for snaplocked attachment of the eyewear directly to other safety equipment such as noise suppression ear muffs, communication head phones, breathing masks and the like.Type: GrantFiled: December 28, 1999Date of Patent: January 28, 2003Assignee: Cabot Safety Intermediate CorporationInventors: James Hall, Keith Fecteau, Raoul Desy, John Salce

Patent number: 6497232Abstract: A quick release mechanism and headpiece for use with a respirator. The quick release mechanism uses a cam latch pivotally attached to a yoke to control the tension in an upper tension strap. In the latched position the upper tension strap traverses the yoke to support and seal the respirator mask against the face of the wearer. In the unlatched position the upper tension straps loosely support the mask below the chin of the wearer in a parked position. In one embodiment, a guide is provided on the yoke to ensure that the mask may be consistently donned and doffed with minimal effort (e.g., potential one-handed donning and doffing). An opening may also be provided in the face mask and optionally in the yoke, and a filter may be disposed within the opening to provide the desired filtration of inhaled gases.Type: GrantFiled: October 16, 2001Date of Patent: December 24, 2002Assignee: Cabot Safety Intermediate CorporationInventors: Keith E.

Patent number: 6338342Abstract: A quick release mechanism and headpiece for use with a respirator. The quick release mechanism uses an over center latch pivotly attached to a yoke to control the tension in a pair of upper tension cords. In the latched position the upper tension cords traverse the yoke and together with a pair of lower tension cords support and seal the respirator mask against the face of the wearer. In the unlatched position the upper tension cords loosely support the mask below the chin of the wearer in a parked position. The upper and lower tension cords are attached to a circular shaped headpiece having a crown piece fitting to the top of the head of the wearer and a base portion fitting to the back of the head of the wearer. The headpiece is advantageously comprised of multiple layers wherein the outer layer is comprised of a rigid material and the inner layer is comprised of a compliant material.Type: GrantFiled: February 22, 1999Date of Patent: January 15, 2002Assignee: Cabot Safety Intermediate CorporationInventors: Keith E. Fecteau, David Honan, Kevin Krauss

Patent number: 6322211Abstract: Eyewear having a temple body that provides for adjustment of the temple length. The temple adjustment housing has an interior cavity. Formed within the interior cavity is a longitudinal groove. The temple adjustment housing has at least one relief cut for receiving at least one projection located on the cylindrical temple tip. The temple tip is inserted into the circular opening and moved horizontally to adjust to the desired length. The temple tip is then rotated to lock into place the projections into the relief cuts.Type: GrantFiled: November 10, 2000Date of Patent: November 27, 2001Assignee: Cabot Safety Intermediate CorporationInventor: Raoul Desy
