Definitions

  • the invention relates to a set of blades intended to equip an electric knife, and more particularly to a set of blades suitable for slicing food such as bread.
  • each blade having in its lower edge a series of notches leaving between they projecting teeth, the hollow of each notch having a chamfer extending from the inner face to the outer face of the blade and thus forming a cutting edge located on said inner face.
  • blades of this kind are well suited for slicing tender foods, such as meat for example, but are not well suited for slicing bread which has a relatively hard and rough crust on a body composed of fairly soft crumbs.
  • the invention aims to provide a solution to this problem.
  • each tooth has a small notch in the shape of an arc of a circle with a concavity of a turn. born downward which extends between the chamfered edges of said tooth and which itself has a chamfer extending from the internal face to the external face of the blade, the ends of this notch thus constituting with said edges of the tooth two points close to each other.
  • Such a set of blades is well suited to slicing bread: in fact, it combines the usual effect of slicing and shearing of the crumb with an effect of planing the crust of the bread thanks to the addition of the pair of points in the end of each tooth.
  • the set of blades shown is intended to equip an electric knife comprising a motor alternately driving in opposite direction two parallel sliding drawers which each receive one of the blades.
  • This set of blades comprises two adjacent blades 10 and 12 arranged in parallel vertical planes and joined to one another according to their internal face 14. Each of these blades 10 and 12 has in its lower edge 16 a series of notches 18 leaving teeth between them protruding 20.
  • each notch 18 has a chamfer 21 extending from the internal face 14 to the external face 22 of the blade and thus forming a cutting edge 24 located on the internal face 14.
  • each tooth 20 has a small notch 26 in the form of an arc of a circle with a concavity facing downwards which extends between the chamfered edges 27 of this tooth and which itself has a chamfer 28 extending from the internal face 14 to the external face 22 of the blade, the ends of this notch 26 thus constituting, with the edges 27 of the tooth 20, two points 30 and 32 brought together.
  • each notch 18 has the general shape of an isosceles trapezoid and the angle a between each side of the trapezium and the line of alignment of the lower points 30, 32 of the blade is of the 'order of fifty degrees.
  • the width of a small notch 26 from one point 30 to the other 32 is of the order of one fifth of the width of a notch 18.
  • this width of the notch 26 is of the order of 'one millimeter, the width of the notch 18 then being five millimeters.
  • the depth P of each notch 18 is, for example, between two and three millimeters.
  • each blade 10, 12 goes. decreasing towards the lower ends of the teeth 20 and the angle b between the internal face 14 of the blade and the chamfer 28 of the small notch 26 is greater than the angle c between this internal face 14 and the chamfer 21 of the bottom of the indentations 18.
  • the angle b is of the order of sixty degrees
  • the angle c is of the order of thirty degrees.
