Definitions

  • the present invention relates to a cutting system for a hair trimmer. It relates more particularly to a movable blade having a plurality of teeth of different height and angle of attack.
  • Hair clippers are now used by both hairdressers and the general public. Lawnmowers for hairdressing professionals are nevertheless more powerful because they are either directly connected to the 230 V sector, or equipped with powerful batteries allowing the use of knives producing a quasi perpendicular cut of the hair.
  • This type of mower has movable blades with deep (long) teeth that do not suffer any limitation in terms of the angle of attack of the hair because very powerful torques of force are available.
  • the mowers are much less powerful and must reconcile the angle of attack of the hair (angle of opening of the teeth), and thus the mowing capacity and the power available. This compromise is reflected in particular by the configuration of the teeth on the movable blade, whose geometric shape must be adjusted to this constraint. To obtain a good cutting capacity, one must open (enlarge) the angle of opening of the teeth but to keep a sufficient number of teeth, the hollows must be shallow which does not allow to cut a lot of hair in few time.
  • etching or "etching" in English, has a considerable advantage provided that the blade to be treated is sufficiently thin.
  • the "etching" method consists in printing a layer of polymer or protective wax on a steel strip and then treating it with an acid to create recesses in unprotected areas. Unaffected areas will be the blade teeth.
  • etching chemical erosion
  • the low blade thicknesses and the limited power thus impose not only a rather large angle of attack of the "guillotine" type of hair, but also a relatively short tooth, since a fine and long tooth would tend to break because of the small thickness. of the blade.
  • the present invention aims to provide an optimized cutting system for a mower "general public". This optimization concerns both the cutting performance with the handicap of a relatively limited power and the reduction in manufacturing cost by using a thin blade that can be manufactured by "etching".
  • the present invention aims to establish a practicable geometry on thin blade for a mower "general public" and for a mode particular of the invention, a relationship between the geometry of the teeth of the movable blade and the force available for mowing.
  • the figure 1 and 2 represent a plan view of a movable blade of the prior art provided for a high power mower with a large tooth length.
  • the figure 3 and 4 represent a plan view of a movable blade of the prior art provided for a "general public" mower with a shorter tooth length.
  • the figure 5 to 10 represent plan views of a series of possible configurations of a movable blade portion according to the invention, wherein the parameters (y) have been varied between 0.5 and 1.8 mm, as well as ⁇ between 9 ° and 15 ° and ⁇ between 18 ° and 30 °. Other configurations were tested where, in addition to the previous parameters, the parameter (x) was varied. For reasons of economy of figures, however, they have not been represented.
  • the figure 11 represents the method of measuring the force exerted by the movable blade, in use, during its back-and-forth movement.
  • the figure 12 represents a detail view in 3 D of the head of the mower provided with the movable blade according to the invention.
  • the performance of a hair clipper depends on many factors that can be all the more limiting as the power available is low.
  • Optimizing the cutting system of a hair trimmer is therefore a multifactorial problem.
  • the present patent application has deliberately chosen to approach this problem by one of its preponderant parameters, which is the geometry of the teeth on the moving blade. This geometry is conditioned by the opening angles combined with the length of the teeth.
  • the present invention does not take into account a possible adaptation of the geometry of the teeth of the fixed blade to the teeth of the movable blade. It is therefore considered that the fixed blade invariably has regular teeth of generally triangular shape and whose length slightly exceeds that of the movable blade to avoid possible injury to the scalp. Nevertheless the following discussion could also apply to the fixed blade.
  • the tooth of the movable blade has been configured to obtain a fairly long tooth with a closed opening angle. It has a shape that is in a way the synthesis between the narrow long teeth generally present on high power mowers (see Fig. 1 ) and the short teeth used so far on low-power "consumer” mowers (see Fig. 1 and 2 ).
  • the force F exerted by the movable blade was measured with a dynamometer.
  • the scheme of this measure is shown in figure 8 .
  • the number of teeth N per unit length is relatively small if the x / y ratios are high, for example greater than 6. This case does not occur. does not require high power and allows the use of etching technology for this type of blade. The mowing capacity of this type of blade is however relatively limited.
  • the object of the present invention was to provide a blade for a "general public" mower, we conducted the tests with lawn mowers of this type. These are not able to deliver forces on the moving blade exceeding about 20 N, they are generally even less than 15 N.
