Definitions

  • the straighteners can be easily operated by someone, such as a salon professional to style another person's hair, it is very difficult to curl one's own hair in this way because of the difficulty in positioning, orientating and winding the straighteners at the back of one's own head. These difficulties are further increased by the limit of rotation placed on the wrist, elbow and shoulder of the average person wishing to carry out the curling action with conventional hair tongs.
  • the proposed device provides the operator with the convenience and facility of conventional heated curling tongs, but with and additional mechanism which will provide the individual with an additional rotation aid to curl the individual's physically inaccessible parts of the scalp.
  • the present invention provides a hair styling tong arrangement provided with heating and cooling devices which has incorporated a means to mechanically rotate the tong elements to provide a curl forming where normally the operator would not physically be able to manipulate the tongs due to the rotational limitations of the wrist, elbow and shoulder joints.
  • the present invention provides hair tongs comprising: a first arm which is moveable between an open position (for inserting hair) and a closed position (for clamping hair); a housing; and a drive mechanism for rotating the first arm relative to the housing.
  • the hair can have a curl imparted by heating it (if a heater is provided for heating, for example, clamped hair) and pulling it through the hair tongs and letting it cool or actively cooling it. If the first arm has a heater, or the first arm holds the hair against a heater, heat can be applied to the hair. When the hair cools the curl will remain.
  • a cooling device can also be provided (for example on the outwardly facing face of the first arm) to cool the hair after it has been heated and thereby to impart the curl more reliably.
  • the hair tongs further comprise a second arm which is moveable relative to the first arm between the open position and the closed position, the first and second arms forming a set of arms.
  • the drive mechanism may then rotate the set of arms.
  • the arm or set of arms are elongate and have a longitudinal axis and the drive mechanism is for rotating the arm or set of arms, preferably around an axis parallel to the longitudinal axis.
  • Rotation of the arm or set of arms can be around the longitudinal axis of the arm or set of arms or around an axis parallel to the longitudinal axis of the arm or set of arms.
  • the rotation of the set of arms will be around the longitudinal axis of the set of arms.
  • the arm or arms may move in a circular path around the longitudinal axis of the set of arms i.e.
  • the housing has a longitudinal axis which is common with the longitudinal axis of the set of arms and the drive mechanism is for rotating the set of arms around the common longitudinal axis. This is a simple system to build.
  • the tongs further comprising an operator selector for selecting an operation of said drive mechanism.
  • the user may select how to rotate the arm. This may include the rotational direction (left handed and right handed users may prefer to rotate the arm in different directions) or it may be preferable to rotate the arm in a certain direction in order to impart a curl right from the root of the scalp rather than a distance away from the scalp.
  • the rotational amount can also be selected. This may be useful depending on user skill in terms of how much rotation can be imparted by the user themselves.
  • rotational speed may be selected.
  • the arm comprises a heater on an inwardly directed face. If two arms are present then both of those may comprise a heater on an inwardly directed face.
  • One of the arms may comprise a cooling device on an outwardly directed face.
  • this face is the face which will be contacted last by the hair, in use, thereby allowing the heated hair to be cooled and thereby set in the curled or otherwise desired shape.
  • the cooling device may be an active cooling device, for example a Peltier element.
  • the apparatus may comprise sensors for sensing the rotational position of the arm relative to the housing. This can help in controlling the apparatus and also help in leaving the first arm in the correct position following rotation.
  • the tongs further comprise a controller for stopping rotation of the arm at a predetermined rotational position relative to the housing. This can be important so that the apparatus can be adjusted for optimal use, for example so that the relative position of the arm to the housing is always the same at the start or end of a curling action.
  • an end of the arm or the set of arms is positioned in the housing. This may be advantageous in terms of safety by ensuring that the drive mechanism can be placed in the housing.
  • the drive mechanism comprises a driving wheel attached to the arm or set of arms for engaging with an inner surface of the housing thereby to rotate the arm or the set of arms relative to the housing.
  • the housing may comprise a first part and a second part, which parts are moveable relative to one another, the first part and the second part being held to the arm or set of arms by magnetic forces.
  • the hair tongs may comprise a hinge which rotatably connects the first and second arms, the first part and the second part being mounted on at least one arm.
  • the arm or set of arms protrude further from the housing than in the closed position. This provides the ability to provide a clutch for engaging the arm or set of arms with the drive mechanism in the closed position. This is a good safety feature because it will not be possible to rotate the first arm or set of arms in the open position.
  • the tongs further comprise a mandrel, the hair tongs being such that, in use, hair is clamped between the first arm and the mandrel. In this way, by rotation of the first arm, hair can be wrapped around the mandrel. If the mandrel is heated and optionally also or alternatively the inner surface of the first arm is heated, then this can be used to impart a curl effectively. In this embodiment, as in other embodiments, preferably the outer surface of the arm is provided with a cooling device. The mandrel is stationary. In this embodiment, it may be important to rotate the first arm towards the scalp in order to obtain the correct curl. A controller may be provided to ensure that. Therefore, in this embodiment the apparatus is constructed and arranged such that when the drive mechanism rotates the arm or set of arms relative to the housing, the arm or arms rotate around the mandrel thereby to wrap hair around the mandrel.
  • the tongs further comprise a second arm.
  • the second arm may be moveable relative to the mandrel in a linear way or pivotal way and rotate, with the first arm, around the mandrel. That is, the first arm and the second arm may have an open position and a closed position (in which they move away from the mandrel, at least at one end).
  • the first arm in the closed, presents an inner surface substantially co-axial to a portion of the outer face of the mandrel with an angular range of between 90 and 180°, preferably between 120 and 180°. In this way, it is not necessary to rotate the arm as far because a turn of up to 180° can be imparted to the hair simply by having the hair between the first arm and the mandrel (which is circular in cross-section) and moving the arm to the closed position so that the hair is clamped between the curved inner surface of the first arm and the curved outer surface of the mandrel.
  • the first arm is moveably connected for movement away from the mandrel so that it can move between an open position and a closed position.
  • This movement is preferably pivotal (rotational) and linear motion. This allows the gap between the mandrel and the arm to be made large without needing a large pivoting movement.
  • this is provided by a hinge which connects the first arm to the remainder of the apparatus.
  • the hinge comprises two linkages, each pivotally connected to an end of the member of the apparatus and at a second end to the arm.
  • the drive mechanism is fixed to the housing.
  • a member which has a point of weakness between the drive mechanism and the housing and/or between the arm and the drive mechanism may be provided.
  • the member breaks at the point of weakness. This can be an important safety feature if, for example, due to operator error the tongs try and pull hair out of a user's scalp. In that case the member will break at the point of weakness rather than the hair being pulled out of the user's scalp.
