Abstract
An attachment of an electric hair trimmer according to the present disclosure is mountable on an electric hair trimmer, and a cutting length which is a length of hair introduced between a fixed blade and a movable blade is adjustable. The attachment of the electric hair trimmer according to the present disclosure includes: a mounting portion which is mounted on a head portion so as to cover a head portion; a slide portion which is mounted on the mounting portion in a slidable manner with respect to the mounting portion such that the cutting length is changed; and a comb which is provided on the slide portion so as to guide hair between the fixed blade and the movable blade.
Claims20
An electric hair trimmer, comprising:
- a head portion;
- a grip portion;
- a movable blade on the head portion;
- a fixed blade on the head portion;
- and
- an attachment mountable on the head portion, wherein:
- the electric hair trimmer is configured such that an angle formed by a moving direction of the movable blade with respect to the fixed blade and a longitudinal direction of the grip portion which supports the head portion is an acute angle or the moving direction and the longitudinal direction are parallel to each other, and is configured to adjust a cutting length which is a length of hair introduced between the fixed blade and the movable blade,
- the attachment comprises:
- a mounting portion mountable on the head portion of the electric hair trimmer so as to cover the head portion when the mounting portion is mounted on the head portion;
- a slide portion which is mountable on the mounting portion of the attachment in a slidable manner with respect to the mounting portion such that the cutting length is changed when the mounting portion is mounted on the head portion;
- a comb formed on the slide portion so as to guide hair between the fixed blade and the movable blade when the mounting portion is mounted on the head portion;
- an operation part which is operable for moving the slide portion relative to the mounting portion, wherein the operation part includes a ring rotatable relative to the mounting portion;
- and
- a movement converting part configured to convert a rotational movement of the ring into a translational movement of the slide portion,
- the movement converting part includes a helical groove, and a projection which is inserted in the helical groove such that the projection is movable in the helical groove,
- one of the helical groove and the projection is formed on an inner peripheral surface of the ring, and
- the other of the helical groove and the projection is formed on an outer surface of the slide portion.
An attachment of an electric hair trimmer which is mountable on the electric hair trimmer, wherein the electric hair trimmer is configured such that an angle formed by a moving direction of a movable blade of the electric hair trimmer with respect to a fixed blade of the electric hair trimmer provided on a head portion of the electric hair trimmer and a longitudinal direction of a grip portion of the electric hair trimmer which supports the head portion is an acute angle or the moving direction and the longitudinal direction are parallel to each other, and is configured to adjust a cutting length which is a length of hair introduced between the fixed blade and the movable blade,
- the attachment comprising:
- a mounting portion mountable on the head portion of the electric hair trimmer so as to cover the head portion when the mounting portion is mounted on the head portion;
- a slide portion which is mountable on the mounting portion attachment in a slidable manner with respect to the mounting portion such that the cutting length is changed when the mounting portion is mounted on the head portion;
- a comb formed on the slide portion so as to guide hair between the fixed blade and the movable blade when the mounting portion is mounted on the head portion;
- an operation part which is operable for moving the slide portion relative to the mounting portion, wherein the operation part includes a ring rotatable relative to the mounting portion;
- and
- a movement converting part configured to convert a rotational movement of the ring into a translational movement of the slide portion, wherein:
- the movement converting part includes a helical groove, and a projection which is inserted in the helical groove such that the projection is movable in the helical groove,
- one of the helical groove and the projection is formed on an inner peripheral surface of the ring, and
- the other of the helical groove and the projection is formed on an outer surface of the slide portion.
