Retractable Neckpiece For Headwear
US Patent:
8024818, Sep 27, 2011
Filed:
Jun 29, 2007
Appl. No.:
11/772027
Inventors:
Steven Roy Davenport - Yukon OK, US
Assignee:
Davenport Innovations, Inc. - Yukon OK
International Classification:
A42B 1/06
US Classification:
2172, 2207, 220913
Abstract:
Apparatus for shading a user's neck. In some embodiments, a support device comprises a flexible, generally U-shaped structure with a laterally extending central portion to accommodate attachment of a proximal edge of a neckpiece, and opposing leg portions which extend from the central portion to engage the headwear. In further embodiments, the neckpiece preferably comprises a layer of flexible material with a proximal end supported adjacent a headwear and an opposing distal end configured to be suspended adjacent to a base of the user's neck. A support portion is formed from laterally extending first and second panels which fold together to form a V-shaped channel circumferentially extending in contact against an outermost rearward surface of the headwear. A flap portion extending from the second panel is moveable between a deployed state to cover the user's neck to a retracted state in which the flap portion is gathered into the channel.
Retractable Neckpiece For Headwear
US Patent:
8291518, Oct 23, 2012
Filed:
Jul 11, 2011
Appl. No.:
13/180106
Inventors:
Steven Roy Davenport - Yukon OK, US
Assignee:
Davenport Innovations, Inc. - Yukon OK
International Classification:
A42B 1/06
US Classification:
2172, 2207, 220913
Abstract:
Apparatus for shading a user's neck. In some embodiments, an apparatus comprises a laterally extending central portion configured to support a neckpiece to cover at least a portion of a neck of a user, and opposing leg portions which extend from the laterally extending central portion configured to engage a headwear to support said neckpiece adjacent said headwear. Each of the opposing leg portions is formed into a substantially G-shape that comprises a first flange configured to extend down between a first surface of an external panel of said headwear and an upturned interior hatband of said headwear; a second flange in overlapping relation to the first flange, the second flange configured to extend up against a second surface of said external panel; and a connecting central portion disposed between and in overlapping relation to both the first and second flanges.
Exhaust Air Transfer Device For Open System Underwater Diving
US Patent:
8418689, Apr 16, 2013
Filed:
May 17, 2010
Appl. No.:
12/781325
Inventors:
Steven Roy Davenport - Yukon OK, US
Assignee:
Davenport Innovations, Inc. - Yukon OK
International Classification:
B63C 11/02, A62B 7/10, A62B 19/00, A62B 23/02
US Classification:
12820127, 12820029, 12820512
Abstract:
Apparatus for use during open system diving to support underwater human respiration. In accordance with various embodiments, an air supply provides a supply of air along a supply conduit. A regulator is adapted for engagement with a diver's mouth to receive air from the supply during an inhale cycle and to direct a mixture of water and exhaust air away from the diver along an exhaust conduit during an exhale cycle. An air/water separator separates the exhaust air from the water in said mixture and directs the separated exhaust air through an exhaust air port. In some embodiments, a one-way stop valve is provided within the air/water separator to prevent back flow. In further embodiments, a bubble diffuser emits the exhaust air as a fine mist of bubbles into the surrounding water.
