Abstract
The beveled face of the cutting blade presents, in cross-section and going from its cutting edge: a first zone making a first angle with the plane face of the cutting blade; and a second zone making a second angle with the plane face of the cutting blade, the second angle being smaller than the first angle. The second angle has a minimum value in the region of the cutting blade close to the shoulder and a maximum value in a region of the cutting blade close to the tip of the cutting blade.
Claims5
1/ Secateurs comprising a cutting blade mounted to pivot about a pin so as to pivot beside a counter-cutting blade, the cutting blade presenting a plane face beside the counter-cutting blade and a beveled face on its other side extending longitudinally from a shoulder situated close to the pin to the tip of the cutting blade, the beveled face of the cutting blade presenting, in cross-section and going away from its cutting edge, a first zone making a first angle with the plane face of the cutting blade, and a second zone making a second angle with the plane face of the cutting blade, the second angle being smaller than the first angle, wherein the value of the second angle has a minimum value in the region of the cutting blade close to the shoulder and a maximum value in a region of the cutting blade close to the tip of the cutting blade.
2/ Secateurs according to claim 1, wherein the value of the second angle increases, e.g. in substantially regular manner, between the shoulder and the tip of the cutting blade.
3/ Secateurs according to claim 1, wherein the value of the second angle varies from about 6° close to the shoulder to about 18° close to the tip, and advantageously from about 7° to about 17°, and preferably from about 8° to about 15°.
4/ Secateurs according to claim 1, wherein the value of the first angle also varies between the shoulder and the tip of the cutting blade.
5/ Secateurs according to claim 4, wherein the first angle has a value of about 20° to 27°, advantageously 22° to 25°, in the region close to the shoulder, and a value of about 15° to 18°, e.g. about 17°, equal or substantially equal to the value of the second angle in the region close to the tip.
