摘要： According to this invention a flexible razor head is provided which features a flexible cap and blade support portion with the blade support portion featuring a segmented guard bar with the spaces separating the segment correlating to the spaces or areas of reduced thickness in the cap. Corrugations present in the blade support portions enable the blade support portion to lengthen in response to shaving forces.

摘要： An improved twin blade razor system having a unitary member positioned between the pair of blades for both spacing the blades and ejecting shaving debris from that space. The unitary member, which may conveniently be of injection molded plastic, includes a spacer portion, an ejector portion, and biasing apparatus connecting the ejector portion and the spacer portion for biasing the ejector portion to a normally retracted position relative to the blades and spacer. The ejector portion is manually displaceable to an advanced ejecting position. The biasing portion may be one or more beam springs connected and configured to reduce distortion and/or stressing of the relatively moving portions of the member during actuation.

摘要： A barber or straight edge razor houses a replaceable blade and includes a body member having a handle and a blade-receiving base portion, a clamp member detachably hinged to the base portion to comprise opposite halves of the razor, and bias apparatus between the razor halves above the hinge for urging the lower portions of the razor halves relatively toward each other to retain the blade therebetween. The blade is releasable by moving the upper portions of the razor halves relatively toward one another. Along a rear gripping portion of the razor halves, one of the halves is structured to assume substantially all of the normal gripping forces so as to prevent inadvertent release of the blade, while the halves include a forward region which is structured to receive special pinching forces to release the blade. Upwardly and rearwardly inclined ridges in the blade-retaining region may be provided to aid in upward seating of the blade as it is moved rearwardly into the razor. Also, the hinge pivot pins may be integral with one of the razor halves and hinge tubes are integral with the other.

The unitary member, which may conveniently be of injection molded plastic, includes a spacer portion, an ejector portion, and biasing means connecting the ejector portion and the spacer portion for biasing the ejector portion to a normally retracted position relative to the blades and spacer. The ejector portion extends across in front of but is substantially discontinuous behind the spacer portion, resulting in a compact front-to-rear configuration for the unitary member which may be housed in a relatively compact twin blade system. The ejector portion is manually displaceable to an advanced ejecting position. The biasing portion may be one or more beam springs connected and configured to reduce distortion and/or stressing of the relatively moving portions of the member during actuation.

摘要： A safety razor contains a blade cartridge in which two blades are rigidly secured. The cartridge has a seat member with an integral blade edge guard disposed transversely along its forward margin. A first razor blade is disposed on a planar surface of the seat member and has its cutting edge located rearwardly of the guard. A second razor blade having a cutting edge located parallel to and rearwardly of the first blade edge is in contact with a mating surface of a cap member. The cap member is secured to the seat member thereby clamping the blades in desired position. The blades are maintained at a predetermined distance apart by spacing means and the guard member has a plurality of projecting teeth transversely arrayed across the guard member forming a comb guard.
