Scissors and sharpening arrangement
View Patent ↗The invention relates to scissors and a sharpening device. The scissors include two blades, each blade having a cutting edge and a back edge which respectively form opposite longitudinal edges of the blade. A pivot connects the two blades for relative movement of the blades between an open condition in which the cutting edge of each blade are apart and a closed condition in which each blade are substantially adjacent and the back edge of each blade projects beyond the cutting edge of the other blade. The blades also include a sharpening condition in which the cutting edge of each of the blades can be sharpened. A biasing means is included for biasing the blades away from the sharpening condition towards the closed condition and/or the open condition. The sharpening device is for scissors including two blades having a cutting edge. The sharpening device includes a hollow housing for receiving the blades of the scissors, a pair of positioning units within the housing arranged in an opposed relationship to receive the blades therebetween when the scissors are inserted into the housing, and a pair of sharpener units located within the housing arranged in an opposed relationship to contact the blades therebetween.
1. Scissors including:
two blades, each blade having a cutting edge and a back edge which respectively form opposite longitudinal edges of the blade;
a pivot connecting the two blades for relative movement of the blades between an open condition in which the cutting edges of the blades are apart; a closed condition in which the blades are substantially adjacent and the back edge of each blade projects beyond the cutting edge of the other blade; and a sharpening condition in which the cutting edge of each of the blades can be sharpened; and
a biasing means for biasing the blades away from the sharpening condition towards the closed condition and/or the open condition the cutting edges of the blades face outwardly away from each other and are disposed on opposite sides of a longitudinal axis of the scissors, and wherein,
wherein in the sharpening condition the cutting edge of each blade projects beyond the back edge of the other blade.
2. The scissors according to claim 1 , wherein the biasing means biases the blades away from the sharpening condition to the closed condition.
3. The scissors according to claim 1 , wherein the biasing means is located in or proximate the pivot.
4. The scissors according to claim 1 , wherein the biasing means is secured to the pivot so as to act between the two blades.
5. The scissors according to claim 1 , wherein the pivot is fixedly secured into a first of the blades so as to allow the biasing means to act between the pivot and a second of the blades.
6. The scissors according to claim 5 , wherein the pivot includes a pivot shaft laterally connecting the blades, the pivot shaft including a first end having a keyed fit with the first blade and a second end configured to allow the second blade to pivot about the shaft relative to the first blade.
7. The scissors according to claim 6 , wherein the second end of the shaft includes a slot in which a first section of the biasing means is secured and the second blade includes at least one adjoining recess in which a second section of the biasing means is secured.
8. The scissors according to claim 1 , wherein the biasing means is a leaf spring.
9. The scissors according to claim 1 , wherein the biasing means is a helical torsion spring.
10. The scissors according to claim 1 , wherein each blade includes a handle which allows a user to actuate the blades between the open, closed and sharpening conditions, the handles being configured to be spaced apart in the open and closed condition and, when in the sharpening condition to be abutting or closer together than in either of the open or closed conditions.
11. In combination, the scissors according to claim 1 and a sharpening device including:
a hollow housing for receiving the blades of the scissors;
a pair of positioning units within the housing arranged in an opposed relationship to receive the blades therebetween when the scissors are inserted into the housing; and
a pair of sharpener units located within the housing arranged in an opposed relationship to contact therebetween the cutting edge of each blade projecting beyond and proud of the back edge of the other blade.
12. Scissors including:
two blades, each blade having a cutting edge and a back edge which respectively form opposite longitudinal edges of the blade;
a pivot connecting the two blades for relative movement of the blades between an open condition in which the cutting edges of the blades are apart; a closed condition in which the blades are substantially adjacent and the back edge of each blade projects beyond the cutting edge of the other blade; and a sharpening condition in which the cutting edge of each of the blades can be sharpened; and
a biasing means for biasing the blades away from the sharpening condition towards the closed condition and/or the open condition,
wherein the pivot includes a pivot shaft laterally connecting the blades, the pivot shaft including a first end having a keyed fit with the first blade and a second end configured to allow the second blade to pivot about the shaft relative to the first blade.
13. The scissors according to claim 12 , wherein the second end of the shaft includes a slot in which a first section of the biasing means is secured and the second blade includes at least one adjoining recess in which a second section of the biasing means is secured.
