DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The invention relates to a hot air hair curling apparatus comprising a motor-driven hair curler body provided with radially arranged teeth.
Such an apparatus is known from DE-35 29 267 A1 and serves to shape hair curls, wherein a strand of hair is wound on the hair curler body in each instance by means of a motor. After a brief treatment period of the curl with hot air flowing from the curler body, the hair curler body is unlocked axially and unrolled from the curled hair accompanied by the application of tensile force of the curl. The arranged curl loses some of its resiliency due to this process, particularly if the curl is not yet conditioned at room temperature prior to being unrolled from the curler body.
SUMMARY OF THE INVENTION
The invention therefore has the object of providing an apparatus, according to the preamble of claim 1, which does not have the aforementioned disadvantage, which further provides multifold possibilities of use, and which is simple to handle and has great mechanical stability.
According to the invention the hair curling apparatus comprises a motor-driven hair curler body which is provided with radially-arranged, retractable teeth. The hair curler body is connected with a gear unit and motor so as to be axially detachable by a clutch, which may be a catch clutch or a permanent magnet clutch. The hair curler body has a shaft axially at one end for a highly mechanically stable mounting which engages with a first and second bearing.
The hair curler body can be drawn out of the hair curl axially. The hair curler body is provided with retractable teeth, so that this hair curl can be conditioned by the room temperature in its original shape. An optimal resiliency of the curl is accordingly achieved.
A particularly simple structure of a tooth retracting mechanism is provided. The hair curler body comprises an actuating element at its free end for the retraction of the teeth. Depending on the tooth retracting mechanism, the actuating element can be constructed so as to be actuable axially or radially as desired.
An advantageous added function is provided in that the actuating element is constructed as a dividing tip. Accordingly, a strand can be divided with the apparatus by means of the dividing tip. The dividing tip can be constructed so as to be axially or radially actuable, as desired, in order to actuate the tooth retracting mechanism.
Multifold possibilities of use and a simple handling of the hot air hair curling apparatus are provided in that the hair curler body is connected with the apparatus by a clutch so as to be axially detachable, so that the hair curler body can be exchanged quickly and simply, e.g. in order to use a hair curler body with a greater curler diameter.
A particularly simple handling for exchanging the hair curler body is provided in that the clutch is provided as catch clutch or permanent magnet clutch, so that a slip clutch, which prevents excessive transmission of torque, can be implemented simultaneously.
In order to compensate for radial tolerances between the shaft journal and the drive clutch disk, the latter is provided with a compensating device.
In order to provide a very high axial stability between the hair curler body and the hot air hair curling apparatus, the hair curler body is connected axially with a shaft at one end and engages with a first bearing in the vicinity of the hair curling body and with a second bearing of the hot air hair curling apparatus at the shaft journal. The forces acting transversely relative to the longitudinal axis of the hair curling body are distributed to the two bearings.
It is advantageous ,to provide the journal with a permanent magnet. Not providing the drive clutch disk within the hot air hair curling apparatus with a permanent magnet has the disadvantage that magnetizable parts inadvertently falling into the apparatus would be very difficult to remove from the apparatus and the operating reliability of the apparatus would accordingly be impaired.
