ATTACHMENT FOR A HANDHELD APPLIANCE FIELD OF THE INVENTION
The present invention relates to an attachment for a handheld appliance, in particular a hair care appliance such as a hot air styling device.
BACKGROUND OF THE INVENTION
In a conventional hot air styling device, air is drawn into an inlet by a fan unit and directed towards the hair by an attachment or head. Depending on the style desired, the air may or may not be heated. The attachment often includes bristles onto which hair is wrapped and held for styling. The air is generally blown out of the attachment normal to the longitudinal surface of the attachment.
SUMMARY OF THE INVENTION
In a first aspect, an attachment for a hair styling apparatus is described, the attachment comprising a casing having an air inlet for receiving an airflow from a hair styling apparatus; a hair engaging member, supported by the casing, and adapted to move relative thereto between a first position and a second position, and wherein a first airflow outlet formed between the casing and the hair engaging member when the hair engaging member is in the first position; and a second airflow outlet, spaced from the first airflow outlet, formed between the casing and the hair engaging member when the hair engaging member is in the second position; and wherein the first airflow outlet is open and the second airflow outlet is closed when the hair engaging member is in the first position; and the first airflow outlet is closed and the second airflow outlet is open when the hair engaging member is in the second position.
The hair engaging member is preferably adapted to move in a rocking movement, relative to the casing. Preferably, the hair engaging member is pivotably supported within the casing and through a central axis of the hair engaging member. It is preferred that the hair engaging member is pivotably supported by pivot pins which mount the hair engaging member within the casing. The hair engaging member preferably has an angle of movement which is in the range from 5° to 30°.
Preferably, the hair engaging member moves into the first position when the attachment is drawn through a user’s hair in a first direction and the hair engaging member moves into the second position when the attachment is drawn through the user’s hair in a second direction opposing the first direction.
Each of the first airflow outlet and the second airflow outlet preferably comprise a plurality of outlet apertures. Furthermore, the plurality of outlet apertures are preferably positioned in a row.
Preferably, each of the first airflow outlet and the second airflow outlet are defined by a respective side face of the hair engaging member and a respective part of the casing. Each of the first airflow outlet and the second airflow outlet is preferably a slot shape. Preferably, the hair engaging member has an elongate form and each of the first airflow outlet and the second airflow outlet preferably extends substantially the length of the hair engaging member.
In a preferred embodiment, the attachment comprises two hair engaging members. Preferably, the casing comprises an outer casing section and an inner casing section, and a ledge of the inner casing section is located between the hair engaging members. In a first configuration of the attachment; a first hair engaging member is preferably in the first position defining a first airflow outlet with the ledge; and a second hair engaging member is preferably in the second position defining a second airflow outlet with the outer casing section. In a second configuration of the attachment; the first hair engaging member is preferably in the second position defining a third airflow outlet with the outer casing section; and the second hair engaging member is preferably in the second position defining a fourth airflow outlet with the ledge. Preferably, the first hair engaging member and the second hair engaging member move synchronously.
Furthermore, the attachment preferably moves between the first configuration and the second configuration under the action of an over centre mechanism. In a preferred embodiment the over centre mechanism is a torsion spring connected between the first hair engaging member and the second hair engaging member. The biasing function of the torsion spring may be realized in several alternative ways. For example, a magnetic latch or weighted moveable members or integrated ball bearings in a detent mechanism may be used.
Advantage is found in the over-centre mechanism for movement of the moveable members which functions to bias the movement of each moveable member in a direction opposing the current orientation of the moveable member, ensuring that the moveable members can tilt in the opposing direction without hindrance.
In a second aspect, an attachment for a hair styling apparatus is described, the attachment comprising: a casing having an air inlet for receiving airflow from a hair styling apparatus; a hair engaging member supported by the casing; a first airflow outlet between the casing and the hair engaging member; a second airflow outlet, spaced from the first airflow outlet, between the casing and the hair engaging member; and internal airflow directing means positioned within the casing to direct air towards the first airflow outlet and the second airflow outlet. Preferably, each of the first airflow outlet and the second airflow outlet are defined, at least in part, by a respective side wall of the casing.
The term “airflow directing means” refers to vanes, baffles, ribs or any other arrangement which guides airflow along an airflow path.
In a preferred embodiment, the internal airflow directing means comprises a plurality of vanes. The internal airflow directing means preferably comprises a plurality of casing vanes connected to the casing. Furthermore, the plurality of casing vanes comprises; a first series of casing vanes located on a first side wall of the casing and adjacent to the first airflow outlet; and a second series of casing vanes located on a second side wall of the casing and adjacent to the second airflow outlet.

Preferably, the vanes in the first series of casing vanes and second series of the casing vanes are approximately evenly spaced.
In a further preferred embodiment, the internal airflow directing means comprises a plurality of edge vanes connected to the hair engaging member. The plurality of edge vanes preferably comprises; a first series of edge vanes located on a first side face of the hair engaging member and adjacent to the first airflow outlet; and a second series of edge vanes located on a second side face of the hair engaging member and adjacent to the second airflow outlet.
Preferably, each vane in the first series of edge vanes is orientated approximately perpendicular to an edge of the hair engaging member adjacent the first airflow outlet, and each vane in the second series of edge vanes is orientated approximately perpendicular to an edge of the hair engaging member adjacent the second airflow outlet.
The vanes in the first series of edge vanes and second series of the edge vanes are preferably approximately evenly spaced. Preferably, the edge vanes and the casing vanes have a similar positioning pattern such that the edge vanes and casing vanes consecutively align with each other.
The hair engaging member preferably has an elongate form, and each of the first airflow outlet and the second airflow outlet preferably extends substantially the length of the hair engaging member.
In a preferred embodiment, the attachment comprises two said hair engaging members. Preferably, each hair engaging member forms, with the casing, a respective first air outlet and a respective second air outlet. The hair engaging members are preferably disposed side by side. The casing preferably comprises an outer casing section and an inner casing section, and a ledge of the inner casing section is located between the hair engaging members.
In a preferred embodiment, the internal airflow directing means further comprises a series of central baffles positioned between the hair engaging members and contacting an inner face of the ledge. Preferably, the series of central baffles extends parallel to an inner side face of a first hair engaging member and an inner side face of a second hair engaging member. Each baffle within the series of central baffles preferably has an open scoop shape adapted to turn the received airflow through approximately 90 degrees, towards the ledge.
Advantageously, turbulent airflow in minimized within the attachment and consequently the audible volume of the hot air styling device with attachment is reduced in use.
Preferably, a first series of inner edge vanes are located on a side face of the first hair engaging member proximal to the ledge. A second series of inner edge vanes are preferably located on a side face of the second hair engaging member proximal to the ledge. The baffles within the series of central baffles, and the vanes within the first and second series of inner edge vanes, preferably have a similar positioning pattern such that the baffles and the vanes consecutively align with each other.
Advantageously, the regular indentations along the side faces of the moveable members in combination with the internal central baffles and internal casing vanes, form jets from the airflow exiting the attachment.
The present invention provides an attachment for a hair styling apparatus comprising: a casing having an air inlet for receiving airflow from a hair styling apparatus; a hair engaging member supported by the casing, an airflow outlet between the casing and the hair engaging member and airflow guiding means extending over the external surface of the hair engaging member and the airflow guiding means comprises a series of ribs; wherein the hair engaging member is elongate in shape, and the airflow outlet extends substantially the length of the hair engaging member.
Preferably, the airflow outlet is defined by a side face of the hair engaging member and a side wall of the casing.
