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.

Abstract

Dans des cisailles du type à ciseaux, composées de deux parties articulées en un point intermédiaire (3) d'une nouvelle version de levier (1, 2) avec fonction de bras de levier et de lames (1'', 2'') ayant une fonction de résistance, le tranchant des lames respectives (1'', 2'') n'est pas aligné par rapport à la goupille de rotation respective.

Claims (5)

1. Ciseau type cisailles pour découpages rectilignes, comprenant deux leviers pivotants en un point intermédiaire au moyen d'une cheville tournante (3) pour réaliser la première version de levier (1, 2) avec une première portion d'un levier étant un levier de force ayant une fonction de poignée (1', 2') et la deuxième portion d'un levier étant un levier de résistance ayant une fonction coupante (1 ", 2"), réalisant ainsi les deux fils coupants non alignés avec la respective cheville de rotation, avec un fil coupant non aligné avec la ligne du respective levier de force et un levier en forme de Z, caractérisées en ce que:
- Les deux respectifs leviers de résistance (1", 2") présentent:
- les fils coupants non alignés avec la respective ligne du levier de force
- les deux leviers (1, 2) étant placés de façon à réaliser essentiellement un Z avec chaque poignée (1' ,2'), plus ou moins ouvert, de façon à représenter deux plans différents, séparés, parallèles l'un à l'autre, durant les opérations de découpage,
- le premier étant le plan de découpage entre les lames coupantes (1", 2") et
- l'autre étant le plan de maniement des cisailles, passant entre les respectives poignées en coïncidence avec le point intermédiaire de rotation (3).
2. Cisailles comme revendiqué en 1, caractérisées en ce que les deux respectifs fils coupants des lames du ciseau (1", 2") sont dentés.
3. Cisailles comme revendiqué en 1, caractérisées en ce que le plus petit des deux fils coupants des respectives lames du ciseau est réalisé avec une scie à dents (2").
4. Cisailles comme revendiqué en 1, caractérisées en ce que le respectif coté opposé de la lame coupante (2") est réalisé avec deux lames parallèles séparées d'une distance égale à l'épaisseur de la lame coupante (1") à tel point que l'action de découpage est effectuée quand la lame coupante est introduite entre les cotés opposés des lames coupantes.
5. Cisailles comme revendiqué en 1, caractérisées en ce que le dit coté opposé de la lame (2") est réalisé avec deux lames parallèles séparées d'une distance égale à l'épaisseur de la lame coupante (1") à tel point que l'action de découpage est effectuée quand la deuxième est introduite entre les cotés opposés des lames, ces derniers étant sous la lame coupante.
