Abstract
A spacing comb arrangement for a hair cutting appliance includes a comb piece configured to be disposed at a skin-facing side of a stationary blade of a blade set. The comb piece has a plurality of comb teeth that define a cutting length of the blade set when the comb arrangement is mounted thereto. The comb piece further has a flexure section configured to urge a frontal portion of the comb piece against the skin-facing side of the stationary blade.
Claims18
A spacing comb arrangement for a hair cutting appliance, the comb arrangement comprising:
- a comb piece that is arranged to be disposed at a skin-facing side of a stationary blade of a blade set, the comb piece comprising:
- a frontal portion,
- a plurality of comb teeth, formed at the frontal portion, that defines a cutting length of the blade set when the comb arrangement is mounted,
- a rear portion arranged to be attached to the hair cutting appliance, and
- a flexure section arranged between the frontal portion and the rear portion, the flexure section being arranged to urge the frontal portion against the skin-facing side of the stationary blade, when the appliance is operated,
- wherein the flexure section defines a deflection axis between the frontal portion and the rear portion,
- wherein the flexure section is integrated in the comb piece,
- wherein a directional bias on the frontal portion is present when the comb piece is attached to the hair cutting appliance, and
- wherein the comb piece is an integrally shaped comb piece being one piece including the frontal portion having the plurality of comb teeth, the rear portion attachable to the hair cutting appliance and the flexure section, and
- wherein at the frontal portion of the comb piece at least one depression is provided, the depression extending parallel to a leading edge of the stationary blade and arranged to be engaged by frontal tips of stationary blade teeth of the stationary blade when the comb piece and the stationary blade are in a defined relative longitudinal position.
The comb arrangement as claimed in 1, wherein, when the comb piece is attached to the hair cutting appliance, the frontal portion and the rear portion are twisted or tilted away from one another about an axis defined by the flexure section to generate a respective counterforce that urges the frontal portion against and into contact with the stationary blade.
A cutting head for a hair cutting appliance, comprising a blade set including a movable blade and a stationary blade that are arranged to be moved with respect to one another to cut hair trapped therebetween, the cutting head comprising a comb arrangement, wherein the comb arrangement comprises:
- a comb piece that is arranged to be disposed at a skin-facing side of the stationary blade of the blade set, the comb piece comprising:
- a frontal portion,
- a plurality of comb teeth, formed at the frontal portion, that defines a cutting length of the blade set when the comb arrangement is mounted,
- a rear portion arranged to be attached to the hair cutting appliance, and
- a flexure section arranged between the frontal portion and the rear portion, the flexure section being arranged to urge the frontal portion against the skin-facing side of the stationary blade, when the appliance is operated,
- wherein the flexure section defines a deflection axis between the frontal portion and the rear portion,
- wherein the flexure section is integrated in the comb piece,
- wherein a directional bias on the frontal portion is present when the comb piece is attached to the hair cutting appliance,
- wherein the comb piece is an integrally shaped comb piece being one piece including the frontal portion having the plurality of comb teeth, the rear portion attachable to the hair cutting appliance and the flexure section, and
- wherein the frontal portion and the rear portion are harder material than a material of the flexure section.
A hair cutting appliance, the appliance being arranged to be moved through hair to cut the hair and comprising a housing, a cutting head, and a comb arrangement configured to be attached to the cutting head, wherein the comb arrangement comprises:
- a comb piece that is arranged to be disposed at a skin-facing side of a stationary blade of a blade set, the comb piece comprising:
- a frontal portion,
- a plurality of comb teeth, formed at the frontal portion, that defines a cutting length of the blade set when the comb arrangement is mounted,
- a rear portion arranged to be attached to the hair cutting appliance, and
- a flexure section arranged between the frontal portion and the rear portion, the flexure section being arranged to urge the frontal portion against the skin-facing side of the stationary blade, when the appliance is operated,
- wherein the flexure section defines a deflection axis between the frontal portion and the rear portion,
- wherein the flexure section is integrated in the comb piece,
- wherein a directional bias on the frontal portion is present when the comb piece is attached to the hair cutting appliance,
- wherein the comb piece is an integrally shaped comb piece being one piece including the frontal portion having the plurality of comb teeth, the rear portion attachable to the hair cutting appliance and the flexure section, and
- wherein the frontal portion of the comb piece includes at least one depression, the depression extending parallel to a leading edge of the stationary blade and configured to be engaged by frontal tips of stationary blade teeth of the stationary blade when the comb piece and the stationary blade are in a defined relative longitudinal position.
A spacing comb arrangement for a hair cutting appliance, the comb arrangement comprising:
- a comb piece that is arranged to be disposed at a skin-facing side of a stationary blade of a blade set, the comb piece comprising:
- a frontal portion,
- a plurality of comb teeth, formed at the frontal portion, that defines a cutting length of the blade set when the comb arrangement is mounted,
- a rear portion arranged to be attached to the hair cutting appliance, and
- a flexure section arranged between the frontal portion and the rear portion, the flexure section being arranged to urge the frontal portion against the skin-facing side of the stationary blade, when the appliance is operated,
- wherein the flexure section defines a deflection axis between the frontal portion and the rear portion,
- wherein the flexure section is integrated in the comb piece,
- wherein a directional bias on the frontal portion is present when the comb piece is attached to the hair cutting appliance, and
- wherein the comb piece is an integrally shaped comb piece being one piece including the frontal portion having the plurality of comb teeth, the rear portion attachable to the hair cutting appliance and the flexure section, and
- wherein the frontal portion and the rear portion are harder material than a material of the flexure section.
