A comb-shaped outer blade that scoops up body hair while suppressing the damage to the skin. The comb-shaped outer blade includes a base part that has a rod shape and extends in a first direction, a comb-blade attachment part that has a plate shape and extends in the first direction and a second direction, open blade parts each of which has a cantilever shape and protrudes from base part in a third direction, and bent blade parts arranged alternately with the open blade parts in the first direction, the bent blade parts connecting the base part to the attachment part. Each of the bent blade parts includes a protruding part that protrudes from the base part along the third direction, bent part that is connected to a distal end of the protruding part, and connecting part that connects bent part and comb-blade attachment part in an inclined state.

Comb-shaped outer blade, blade unit, and electric razor

The present disclosure provides an electric razor that can further suppress irritation to a skin. An electric razor of the present disclosure includes a body configured to be gripped by a user, a head having three or more blade blocks, and a head support connecting the head and the body to each other. The head support supports the head in a floatable-and-sinkable way with respect to the body. The head includes a case that supports the three or more blade blocks, and a blade float that allows each of the three or more blade blocks to float and sink with respect to the case. A first urging force with which the head support urges the head in a floating direction is larger than a second urging force with which the blade float urges the plurality of blade blocks which are one or more less than three or more blade blocks in a floating direction. The first urging force is smaller than a third urging force with which the blade float urges all of the three or more blade blocks in the floating direction.

Electric razor

The present disclosure provides an electric razor in which a support frame that supports an outer blade and an inner blade, which constitute a block, can be smoothly removed. An electric razor according to the present disclosure includes a main body gripped by a user and a head having a blade block including an outer blade (that is, a slit blade, a mesh blade) and an inner blade disposed inside the outer blade and sliding with respect to the outer blade. The head includes a base, a support frame that supports the blade block so as to be able to float and sink, a case held by the support frame, a hook that locks the support frame or the case to the base, and at least one push-up member that urges the support frame in a direction away from the base.

A hair cutting device includes a grip, a head disposed external to one end of the grip, the head including a cutting unit that works on hair, and a joint connecting the grip and the head. The joint includes a base connected to one of the grip and the head, and a slide portion connected to the other of the grip and head and held to be slidable within a predetermined area on a slide plane that is a plane intersecting an alignment of the grip and the head. Accordingly, the hair cutting device including the head that has an excellent ability to lessen impact which is made when the head hits the skin and to follow the skin surface is provided.

Hair cutting device

Provided is a method of producing an outer blade for a hair cutting device from a material including bars that each have a shape of a rectangular stick and are arranged at predetermined intervals. The material is placed on a base. Next, a first tool having a leading end that has a gradually increasing width in a direction away from the material is used to press at least one part of each of the bars in a direction from a counter base-side first face of each of the bars toward a base-side second face of each of the bars. An edge of the first face of each of the bars is caused to project widthwise and to move toward the second face to be farther from an intermediate part of the first face.

Method of producing an outer blade for a hair cutting device

An outer blade for a hair cutting device, the outer blade being mounted to an end of a main body of the hair cutting device, includes bars that each have a shape of a rectangular stick and are arranged at predetermined intervals. The outer blade also includes, at a skin-surface-contact-side first face of each of the bars, an agent holding part configured to hold an agent that is a substance having a predetermined effect on a skin surface, the agent holding part being a surrounded recess heading from the skin-surface-contact-side first face of the bar toward an inner-blade-side second face of the bar. Thus, the agent such as foam or gel can be held by the agent holding part at the skin-surface-side face of the outer blade, and friction can be reduced between the outer blade and the skin surface by the agent held by the agent holding part.

Outer blade for hair cutting device and hair cutting device

A slit blade block is provided with a slit outer blade, a comb component, and an outer blade connector to which the slit outer blade is fixed. The comb component is sandwiched between and held by the slit outer blade and the outer blade connector when the slit outer blade is fixed to the slit connector.

Slit blade block and electric razor

Electric shaver includes body, head having blade block, and head supporting part connecting body with head. Head supporting part includes swing supporting part supporting head swingably about two swing axes, and head float part so that head is movable up and down with respect to body. This configuration allows head to swing about the two axes, and thus head easily follows undulations of skin. Head is movable up and down with respect to body, and thus head sinks with respect to body when head is strongly pressed against the skin. The aspect provides electric shaver that has a high follow-up performance of head swinging according to undulations of skin and hardly irritates the skin strongly.

Electric shaver

This slit blade block includes multiple comb teeth adjacent to multiple outer blade pieces. Each comb tooth has a leading end surface, and a protruding part protruding in a direction away from the outer blade pieces. The protruding parts include an apical part that is the outermost end in said direction away from the outer blade pieces. The leading end surfaces of the protruding parts are positioned between the leading end surfaces and the base end surfaces of the adjacent outer blade pieces. Length Lin the height direction, defined by the apical part of the protruding parts and the leading end surfaces of the protruding parts, is less than or equal to thickness Lof the outer blade pieces, defined by the leading end surface and the base end surface of the outer blade pieces.

Slit blade block and electric razor having slit blade block

Head () of electric shaver () includes blade unit (), head case () supporting blade unit (), and rotary member () rotatably supported by head case (). Blade unit () includes outer blades (and) that contact with a target area and inner blades (and) provided corresponding to outer blades (and) and configured to make a reciprocating move relative to outer blades (and). Blade unit () and rotary member () are coupled so as to move together relative to head case () in a height direction of head case (). This embodiment enables the head of the electric shaver to move smoothly on the skin.

A height dimension Dof a head sectionis smaller than a front-back dimension Dof the head sectionThe head sectionhas therein a linear actuatoras a drive source. Inner bladesare coupled to a drive coupling section protruding form an actuator main section. A height dimension of the actuator main section is smaller than a front-back dimension of the actuator main section.

An electric shaver includes a rod-shaped body part, a head part, and an interposer. The head part projects from one end portion, in a longitudinal direction, of the body part and swingably attached to the body part. The head part includes a shaving portion and a drive mechanism. The interposer is configured to support the head part swingably about a first swing axis parallel with a longitudinal direction of the shaving portion, and to be supported on the body part swingably about a second swing axis orthogonal to the projecting direction of the head part and orthogonal to the first swing axis.
