Patent number: 10562199Abstract: A novel connecting member of razor is shown to have a plurality of chamfers on at least one finger disposed at an end of an arm. Desirably, both arms have two chamfers on each finger. Each chamfer is disposed having an angle to a top surface of the finger. Though any angles are contemplated in the present invention, the angle of the first chamfer is desirably smaller than the angle of the second chamfer. The bearing length of the finger and the first chamfer angle are together desirably balanced to provide an optimal clearance for the fingers into openings on either end of the back of the housing and improve the pivot operation and control for the user.Type: GrantFiled: January 7, 2015Date of Patent: February 18, 2020Assignee: The Gillette Company LLCInventors: Neil Lettenberger, David Wayne Morris

Patent number: 10363674Abstract: A novel guard structure of a razor is shown including rows of elongated hard plastic protrusions having rounded (e.g., not sharp or pointed) tips arranged on a tip curved profile. The rounded valleys between the protrusions are also arranged on a curved profile which may be different than that of the tip curved profile. The valleys encompass an inner protrusion volume which increases going back to front end of the guard structure. Preferably, the front end volumes are larger than the back end inner protrusion volumes to assist in trapping and distributing shaving aid. In one embodiment having six protrusions, the inner protrusion volume between a second and third protrusion is the largest, while a volume between first and second protrusion is the second largest volume. The guard structure is disposed in front of the blades formed within the housing and may extend past the front end of the housing.Type: GrantFiled: October 2, 2017Date of Patent: July 30, 2019Assignee: The Gillette Company LLCInventors: Stephen Charles Witkus, Neil Lettenberger, Armando Miguel Hurtado
