BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates to an instrument for cutting hair, as one of the instruments which are normally used by hairdressers, capable of simultaneously cauterized the cut hair ends.
BACKGROUND ART
Until now there has not been any relation among the functions performed by means of conventional scissors by hairdressers and other conservatory acts which are performed on hair by means of other specialized instruments, in particular for preventing the growth of bifurcated hair ends, which is a frequent but not exclusive concern of women keeping relatively long hair. It has been heretofore a common practice of hairdressers to cure the tendency of hair to bifuracate by flame treating the hair, using a candle or a special torch. These treatments are time consuming and unpleasant to both the customer-patient and the operator, moreover the risks of inadvertently overdamaging the hair or to accidentally cause more serious damages is attendant.
SUMMARY OF INVENTION
A main objective of the present invention is to provide an instrument for simultaneously cauterizing the cut hair ends while cutting hair in a safe and effective manner, while causing the least discomfort to the customer.
These objectives and other advantages are achieved by means of the instrument object of the present invention which consists in a hair cutting instrument having, under this aspect a substantially common configuration, while the cutters or the cutter thereof is electrically heated to a temperature comprised in the range of 150.degree. C. and 300.degree. C. for cauterizing the hair being cut by the blade.
It has been found that hair cut with a blade held at such a high temperature shows a markedly reduced tendency to bifurcate upon growth and the hair comparatively appears to benefit overall from the high temperature cut treatment, by developing an improved glossy appearance and an overall reinvigoration. These positive effects may be attributed to the simultaneous cauterization of the cut produced in the hair which prevents a tendency of the hair to desquamate or to "loosen" at the freshly produced cut which may originate degenerative processes such as the bifurcation of the hair and the like. In this respect, the high temperature cut produced by the instrument of the present invention may be seen as providing a positive aseptic "sealing" of the cut which prevents degenerative effects after the cutting.
According to a first embodiment of the invention, the instrument is a pair of scissors, at least a blade or preferably both blades of which are heated. However other embodiments may be in the form of single blade hair cutting instruments such as a razor and also of a comb-razor, as often used by hairdressers in place of scissors for performing special hairdressings. The cutter or the cutters, as the case may be, are preferably heated by electrical heaters which are preferably set into an especially designed blade holder portion of the instrument in order to generate the required heat as close as possible to the cutting edge. Most preferably the instrument has heater elements incorporated therein and connected to a low voltage power supply through an insulated cable and most preferably the instrument is also provided with a thermocouple set in proximity of the heated blade and which is connectable through the same (multiconductor) insulated cable to a temperature control unit in order to maintain the cutting blade or the cutting blades to a presettable constant temperature during the utilization of the hair cutting instrument. The temperature control-power supply unit may be combined in a wheeled caddie and be provided with a panel including all the control and temperature preselection switches and with a display for monitoring the correct temperature to which the cutters are heated.
The different aspect and advantages of the haircut instrument of the present invention will be more easily appreciated through the following detailed description of several embodiments and reference to the attached drawings.
