  • Patent number: 10583574
    Abstract: An integrated shaving mechanism (ISM) comprises a 28- x 50-mm perforated arbor of 40-mm cylindrical radius supporting a 50-?m 300-mg inverted-headfoil-like cutterfoil with a 25×40-mm cutting pattern, held slideably under an attached complementary-patterned headfoil. Arbor, cutterfoil, and headfoil provide a few-mm thick shaving mechanism coupled to a shaver body having a motor and eccentric drive shaft that in minor design variations scans the cutterfoil either ±1-mm in reciprocation (R-ISM) or 1-mm-R in circulation (C-ISM) at 0.16K-cpm. With its 10-cm2 area of 0.7-mm-spaced cutting edges capable of firm facial contact, it cuts short hairs at up to 10× the rate of conventional shavers for fast closest-cutting. Arbor-supported cutterfoils and headfoils can be fabricated as thin and lightweight monolayers and multilayers of hard materials and coatings by mechanical and non-mechanical processes. ISMs can be embodied in the size and shape of reciprocator and rotary shavers.

The blade head assembly can include a second blade set, the second blade set extending generally in parallel with the longitudinal axis, the first and second blade sets arranged facing away from each other such that the shaving direction of the blade head assembly can be altered by rotating the safety razor about the longitudinal axis. The safety razor can further include a biasing element for resisting pivotal motion of the blade assembly about the longitudinal axis and a control mechanism operable to selectively limit the pivotal motion of the blade head assembly.

  • Patent number: 8732964
    Abstract: The invention relates to a hair removal device such as for example an electric shaver or a wet shaver, comprising a main device element (10, 20) which accounts for the major portion of the overall weight, and a separate element (30, 40) which can be coupled therewith and which comprises for example a wet-shave blade cartridge (40). The separate element (30, 40) is connected to the main device element (10, 20) via a coupling (23, 33). Said coupling (23, 33) is designed to open under the effect of forces that exceed a minimum force. When the hair removal device (100) is dropped, the separate element (30, 40) is not damaged despite the comparatively greater weight of the hair removal device.

  • Patent number: 8689448
    Abstract: An outer frame of a razor head includes two side parts, a front part and a rear part connecting the side parts. An inner side wall of each side part provides a positioning block which has a first plane for mounting and supporting razor blade assemblies. Resilient arms are connected with side walls of the positioning blocks. Each resilient arm includes a leg part connecting the positioning block and a head part connecting an end of the leg part. An inclination angle between the leg part and the first plane is in the range of 25°˜30°. The head part is extended out of the first plane. The resilient arm can provide a suitable supporting force to a razor blade holder within its allowable range to be prevented from being fractured easily, and in turn improve the using performance of the outer frame and extend its lifetime.

  • Patent number: 8671576
    Abstract: The divisible head razor device provides a removable blade case with two blade heads slideably disposed therein. The handle of the device terminates in a carrier having a thumb wheel within the neck. The gear shaft in turn rotates the distally disposed rack gear. Two gear arms are disposed in contact with the rack gear. Each gear arm is adjusted laterally by the thumb wheel. Each gear arm is connected to an extension, each extension connected to a vertical section, each vertical section connected to a right angle section. Two blade heads are disposed slideably side by side within the blade case. Each of the blade heads removably connects to one of each of the right angle extensions. The blade heads are controlled by the thumb wheel such that the heads can be positioned together or apart with a gap determined by a user.

    Abstract: Disclosed herein is a hair removal apparatus (100) having a base body (10) and a slide (20), which is mounted thereon to be movable (displaceably). At least one wet shaver unit (40) comprising a razor blade, such as a blade cartridge for wet shaving, is mounted on the slide. Due to the mobility of the slide (20), this wet shaver unit (40) is protected from damage in the event of impact of the hair removal apparatus, e.g., in a fall to the floor. Certain target positions of the slide (20) can be secured with a slip clutch, such that they become unlocked on exceeding a minimum force that is acting and thereby release a movement of the slide.
