Definitions

  • the present invention relates to apparatus for grooming hair.
  • WO-00347 and French Patent 2435 925 show devices of this kind which utilise a spiral chamber into which the hair is sucked and heated over a significant period of time.
  • WO-00347 a significant cooling period is said to be necessary following the heating period in order to achieve a permanent set.
  • U.S. Patent 4 210 162 a similar type of permanent styling is described using an elongate chamber open at the side.
  • the device normally uses a floor mounted motor unit with a double duct for suction and blowing. This can be replaced by a portable motor unit which is adapted to be connected to the double duct connection on the chamber unit.
  • apparatus in the form of a hand-held appliance for grooming hair comprising: means (a) for applying suction to a local portion of the head, means (b) for applying heated air to the said portion and/or to an immediately adjacent portion, the apparatus including an electric motor drivingly connected to an impeller and arranged to enable a small section of hair to be lifted and dried by a suction-induced air current from the inlet of the impeller and by hot air from the outlet of the impeller, characterised in that the suction means (a) comprises a first generally straight duct portion having an inlet nozzle for engaging the hair arranged in a plane generally perpendicular to the direction of air flow, an outlet in communication with the suction side of the impeller, and an air-pervious hair blocking means located between the nozzle and the outlet the heat applying means (b) including a second duct portion, generally co-axial with the first duct section.
  • the duct sections and impeller are arranged on a common axis, the impeller is of centrifugal or aerofoil type, having a central inlet at the outlet of the first duct and a shroud defining an extension of the second duct portion, and wherein an electric resistance heater is cireumferentially arranged within the said second duct extension.
  • the hair blocking means is adjustable in position lengthwise of the suction duct.
  • a central spindle extends centrally through the first duct section and centrally through the hair blocking means.
  • the hair blocking means is shaped to provide a part-toroidal surface which is concave on the suction nozzle side.
  • Figure 1 is an axial sectional view (in part) of a form of appliance in accordance with the invention
  • Figure 2 is a rear end view of the embodiment of Figure 1
  • Figure 3 is an exploded perspective view of a modification of the embodiment of Figure 1
  • Figure 4 is a view corresponding with the forward end portion of Figure 1 of the modification of Figure 3
  • Figures 5 and 6 are axial sectional .views of extension duct sections of different length for the modification of Figures 3 and 4.
  • Figure 7 is an axial sectional view of a modified duct arrangement
  • Figure 8 is an end view of the arrangement of Figure 7.
  • Figures 1 to 5 are approximately to scale and the overall length of the embodiment of Figure 1 along the axis X-X is 24.5 cms.
  • the motor M is a 290 watt series-wound AC motor producing 13,000 rpm.
  • the motor shaft 101 drives a seven bladed aerofoil fan 102.
  • the handle 103 is formed with the external cover portion 104 in two mouldings 104a, 104b (Fig. 3) which fit along
  • the cover portion 104 is provided with dished apertures 105 which provide a current of air through the motor for cooling purposes. As will become apparent, this air draft, which is partially. heated by the motor combines with the warm air draught down the outer (130) of two coaxial ducts 130,131. Switches 106,106' for the motor and heating element 117 are provided in the handle 103, which is provided with access apertures 106a. (Fig. 3), and the electric lead 106b passes through the bottom of the handle.
  • the cover portion 104 is provided with a channel section 107 to clear the motor brush housings indicated at 108.
  • the motor is maintained in position within cover portion 104 by moulded ribs shown at 109,110,111, the last having an aperture for a bolt 111a (Fig. 2) connecting the mould halves 104a,104b.
  • a second bolt 133a held in projections 133 secures the handle 103 with the aid of spacers 134 (Fig. 11) which are omitted in Fig. 1.
  • Forward of the fan 102 is situated an inner duct extension moulding 112 which is formed with a rearward, radially outwardly stepped shoulder 112a and a radial flange 112b which seats at its extremity in a channel moulding 113 formed in an annular outwardly projecting portion of the moulding 114.
  • the flange 112b is formed with elongate recessed portions 114 in its periphery to provide slots for the passage of air directed centrifugally outwardly by the fan and which ultimately exits through duct 130.
  • the shoulder 112a receives a flange 115a and an inner duct foward moulding 115.
  • the forward end of the outer duct is formed as a moulding 116 having a flange 117 which seats within a channel 118 formed at the forward end of the casing 104.
  • the inner duct moulding portion 115 of Figure 1 is constituted by a differently formed member in Figure 2 which will be described subsequently.
  • a spiral electric heating element 119 surrounds the inner duct extension member 112 upon which it is supported by a refractory support 119a (Figure 3).
  • Figures 1 and 3 show different arrangements of the heating element and support.
  • the embodiment of Figures 1 to 5 exhibits a preferred feature of the invention according to which there is provided a hair spreading and blocking means located within the suction duct.
  • the hair spreading means takes the form a piece of mesh material 120 e.g. of nylon or stainless steel which extends across the suction duct 131 (defined by mouldings 115,112).
  • the hair spreading means is adjustable in position lengthwise of the suction duct 131. This is accomplished by mounting the periphery of the mesh in a ring moulding 121 which is connected by spokes (not shown) to a hub 122 which is threadedly enagaged with a threaded shaft 123.
  • the shaft 123 is in turn supported on a spoked supporting structure 124 which is rigidly mounted within shoulder 112a and which supports a second gauze 120a for safety purposes.
  • the outer periphery of the ring 121 is grooved to engage with longitudinal splines 125 on the inner surface of the forward inner duct moulding 115.
  • the moulding 115 is rotatably engaged within the moulding 112 and projects forwardly of the outer duct moulding 116.
  • the forward end of moulding 115 can be held by the fingers and rotated to cause the ring 121 and mesh 120 to travel along the shaft 123 to any desired position within the suction duct 131.
  • the hair spreading means located quite close to or in some cases at the extreme end of the suction duct. This allows the hair to be drawn out and manipulated in the course of drying to produce a bunched or curled effect rather than cause it to be stretched straight outwardly from the roots.
  • the latter may be arranged in one of a set of removable duct members, the set including mesh supports arranged at different positions.
  • the duct members may be constituted by inner duct sections or sections providing inner and outer duct parts.
  • F igures 3, 4, 5 and 6 show yet another arrangement for providing for the mesh 120 at different positions within the inner duct.
  • the inner duct section 115' corresponding to the section 115 of Figure 1 is somewhat shortened in length and the mesh 120 is fixed adjacent the forward end.
  • the outer duct member 116' corresponding to the member 116 of Figure 1 is also shortened in length. Longitudinally extending shallow tapered ribs 135 are provided at spaced positions on the outer surfaces of duct sections 115' and 116' to provide for the frictional attachment of extension duct sections of different length as illustrated in Figure 5 and Figure 6.
  • Each of these consists of a single rigid moulding comprising an outer duct portion 136 and an inner duct portion 137 interconnected by four cireumferentially spaced spokes 138.
  • the rearward inner surfaces of the ducts are rebated with a shallow inward taper at 139 so that the rebated surfaces may frictionally engage with the tapered ribs 135.
  • a safety mesh 121 may be provided at the rearward end of inner suction 115'.
  • an adaptor piece similar in construction to Figures 5 and 6 may be used to close off the suction duct and extend the outer duct preferably with an inward taper so as to convert the apparatus to a conventional hair dryer.
  • the suction duct is defined by a straight cylindrical duct portion 215 and the hot air duet is defined between the duct wall 215 and an outer straight cylindrical duct portion 216. At the front end these ducts are substantially coterminus. At the rear end they are mounted to portions of the fan and motor housing generally indicated at 212 and 213.
  • the hair spreading and blocking means in the form of a self-supporting mesh e.g. of wire 220 is mounted on a sliding ring 221. To enable control of the sliding ring 221, diametrically opposite slots 224,225 are provided in the outer duct piece 216 in correspondence with similar slots 225,226 in the inner duct piece 215.
  • Plate-like ribs 227,228 extend through the slots and connect the ring 212 to sliding handle pieces 229, which may be substituted by a continuous ring which slides along the outer duct piece 216.
  • a central spindle 230 is preferably provided, although it can be omitted if desired. This can be mounted by means of ribs 231. It can serve as an additional support to the mesh, which requires to be apertured in order to slide along the spindle and if necessary reinforced by an additional ring member.
  • the mesh is shaped as shown in Figure 7 so as to provide a toroidal depression 232 which is concave towards the nozzle end (i.e. convex towards the impeller).
  • This has been found to be extremely beneficial to achieving good styling and this is particularly so if the spindle 230 is employed, when the hair will tend to curl around the spindle to produce extremely pleasing effects.
  • the device is adapted to be moved fairly rapidly and continuously over the subjects head so that individual styling techniques can be obtained. It is an extremely flexible styling tool when compared with tools which merely produce a set curl to a particular lock of hair. It will be apparent that the features of any one particular embodiment described can be used in combination with features of another embodiment where suitable.
