Definitions

  • the subject of this invention is a blade rectilinear shear with relative slide of the blades against each other.
  • Shears with cutting blades with relative slide of the blades against each other are already known in the present state of art. However, they are of a specific type and have essentially pruning functions in agriculture (FR-A-966992 WEILAND). In FR-A 966992 both the cutting edges are misaligned with the respective rotation pin, but only one cutting edge is misaligned with the respective force lever line and only one lever is Z-shaped, this solution do not allowing cutting plates and foils or sheets easy, because this is obliged to flect in cutting operation.
  • the scope of this invention is to realize cutting shears which integrate the function of the traditional shears and which are able to carry out a cutting function that traditional shears are unable to do, particularly for the cutting of special materials and, above all, flat parts or cuts in areas of difficult access.
  • this invention solves the problem by realizing scissor-type shears for rectilinear cuttings, involving two levers hinged at an intermediate point by a rotation pin (3) to realize first version levers (1, 2) with a first portion of a lever being force lever having a function of handles (1', 2') and the second portion of a lever being resistance lever having a cutting function (1", 2"), thus realizing both the cutting edges misaligned with the respective rotation pin, with a cutting edge misaligned with the respective force lever line and a lever Z-shaped, characterized by the fact that:
  • a relative slide is thus obtained between the respective cutting blades which favours the shearing action.
  • the respective cutting edges are conveniently serrated in order to prevent eventual slipping of the product to be cut.
  • the counter blade can be double instead of being single, as in the traditional shears. That is to say, composed of two parallel blades spaced apart by the thickness of the cutting blade so that this can pass closely between them. A safer cutting action is thus obtained as the blade is "guided" between the respective counter blades.
  • the counter blade is the lower one. It is possible to work better with this solution, for example, to be able to cut sheets without deviations.
  • Figure 1 shows one of the possible forms of realization of the shears as per the invention.
  • Figure 2 schematically shows the shearing system and visualizes an alternative way of cutting by twin counter blades so that the cutting blade may insert itself between them.
  • the shears or more properly, the scissors according to the traditional technique are composed of two elements 1, 2 hinged at an intermediate point 3 so as to realize a new version of lever shears in which the handle 1', 2' represents the leverage part whereas the blades 1", 2" represent the resistance as the fulcrum 3 is in an intermediate position.
  • One of the two cutting edges is conveniently realized with saw teeth so as to prevent the cut material being shifted by the relative sliding of the blades in a blunt area.
  • the scissors may conveniently bear a spring for self- opening.
  • a means of hanging up the shears when closed may obviously be foreseen such as, for example, a hook or similar means realized on the respective handles. This means is not illustrated but is easily imaginable.
  • the "Z" shape thus conceived determines a transmission system of force similar to a man's jaw with the characteristic that the respective blade is angled in respect to the part which connects it to the pivoting point.
  • the cutting counter blade 2" may also be double, that is to say it realizes a sort of pocket so that the cutting blade 1" passes closely between the pair of counter blades which, for this scope, have the corresponding thickness of the cutting blade between them. In this way the cut will be further assured both for cutting and for an eventual tearing movement.
  • the shears can also act as pincers.

Claims (5)

1. Schere ähnlich einer Haushaltsschere für geradlinige Schnitte, mit zwei Hebeln, die an einem mittleren Punkt an einem Rotationsstift (3) aufgehängt sind, so daß sich Hebel der ersten Version ergeben (1, 2), wobei der erste Teil eines jeden Hebels, der als Krafthebel wirkt, eine Griffunktion hat (1 ',2') und der zweite Teil eines jeden Hebels, der als Widerstandshebel wirkt, eine Schneidefunktion hat (1", 2").
Dadurch sind beide Schneidekanten mit den entsprechenden Rotationsstiften verlagert, wobei eine Schneidekante mit der betreffenden Krafthebellinie verlagert ist und ein Hebel Z-förmig, charakterisiert dadurch, daß
- beide betreffenden Widerstandshebel (1 ", 2") die mit den betreffenden
- Krafthebellinien verlagerten Schneidekanten aufweisen, und daß
- beide Hebel (1,2) Z-förmig sind und jeder Griff (1',2') mehr oder weniger offen in der Form ist, so daß beim Schneiden zwei verschieden versetzte parallele Flächen zusammenwirken, wobei
- die erste die Schneidefläche zwischen den Schneideblättern (1", 2") ist und
- die zweite eine scherenbedienende Fläche ist, die sich zwischen den betreffenden Griffen, zusammenfallend mit dem aufgehängten Vermittlungspunkt (3), bewegt.
2. Eine Schere wie nach Patentanspruch 1, charakterisiert dadurch, daß beide Schneidekanten der als Schere funktionierenden Blätter (1", 2") gezähnt sind.
3. Eine Schere wie nach patentanspruch 1, charakterisiert dadurch, daß mindestens eine der beiden Schneidekanten der Scherenblätter mit Sägezähnen ausgestattet ist (2").
4. Eine Schere wie nach Patentanspruch 1, charakterisiert dadurch, daß das Vorschneidemesser (2") mit zwei parallelen Blättern ausgestattet ist, deren Entfernung voneinander so groß ist wie die Dicke des Schneideblattes (1"), so daß die Schneidefunktion ausgeführt wird, wenn das Schneideblatt zwischen die Vorschneidemesser geschoben wird.
5. Eine Schere wie nach Patentanspruch 1, charakterisiert dadurch, daß besagtes Vorschneidemesser (2") mit zwei parallelen Blättern ausgestattet ist, deren Entfernung voneinender so groß ist wie die Dicke des Schneideblattes (1 "), so daß die Schneidefunktion ausgeführt wird, wenn letzteres zwischen die Vorschneidemesser geschoben wird, wobei sich diese unter dem Schneideblatt (1") befinden.
