Definitions
- the present invention relates to hand tools such as a pair of scissors or a pair of pliers, in particular pairs of scissors for cutting hair by a hairdresser.
- hand tools such as a pair of scissors or a pair of pliers, in particular pairs of scissors for cutting hair by a hairdresser.
- the hairdresser must be able to keep the pair of scissors that he uses in a substantially constant position, practically in a vertical plane, regardless of the place of the cut on and around the head of the client and the relative position thereof which, obviously, does not remain immutable during a whole hairdressing session.
- Scissors are known which are suitable for cutting hair, for example the scissors described in document FR-A-2 627 421, comprising first and second elements articulated around an intermediate common axis, each element comprising an extended cutting blade beyond the axis of articulation by a branch provided with a receiving member adapted for operation by the end of a hand finger of the hairdresser.
- the receiving members are rings located in the longitudinal plane of each of the articulated elements.
- the pair of scissors is held in the hand by engaging the ring finger of the hand in the ring of the first branch, the ring of the second branch being designed to receive the thumb of the hairdresser with whom the latter controls, in its plane, the movement of the second branch making the cut, the first branch held by the ring finger remaining substantially fixed.
- Document FR-A-2 627 421 provides for this that each of the branches provided with the rings in which the fingers of the hairdresser engage are provided with an adjustable connection, allowing each of the rings to pivot freely along a longitudinal axis. pivoting parallel to the longitudinal axis of each of the articulated elements. It is thus possible to modify the inclination of the plane of the rings relative to the cutting plane of the blades.
- the device described in this document requires using the two hands of the hairdresser to adjust the pivoting of one and the other of the rings around their respective longitudinal pivot axis.
- the presence of the closed transverse nozzle practically prevents the easy adjustment of the axial position of the finger in the ring.
- the adaptation of the thumb in the second receiving member, pressing against the bearing face of the open ring induces a force for pivoting the tool, force which the user must balance by the ring finger introduced in the first receiving organ. This results in unnecessary fatigue of the fingers.
- the invention also makes it possible to improve the comfort and the holding of the tool by the user's ring finger, by allowing an adaptation tion with little play of the ring finger in the corresponding receiving member, and without preventing the user from folding his ring finger.
- Another problem proposed by the invention is to allow the adjustment of the orientation of the cutting or pivoting plane of the articulated elements, relative to the direction of the phalanxes of fingers engaged in the receiving organs, this adjustment having to be ensured directly by the only hand engaged on the tool, without requiring the use of the other hand of the user.
- the second receiving member of the second articulated element comprises a longitudinal end portion of the second branch, associated with a transverse support structure developing substantially in the pivot plane of the articulated elements opposite the first articulated element,
- the support structure may advantageously be a rod, one end of which is integral with the branch of the second articulated element, the said rod being curved in an arc according to a concavity turned towards the free end of the branch of the second articulated element, and along a greater radius. at the average radius of one user inch; the support structure preferably forms an arc of about 90 degrees.
- the support structure is adjustable in longitudinal position, to vary and fix the distance between the support structure and the intermediate common axis.
- This adjustment can be obtained by providing a set of several removable and interchangeable support structures each comprising a base which is fixed in a receptacle of the branch of the second articulated element, the rods of support structures being offset longitudinally relative to each other. to others on their respective bases.
- FIG. 1 is a general side view of a pair of scissors according to the invention.
- a tip 13 is engaged in the ring 12.
- the tip 13 constitutes a generally cylindrical receiving member in which the ring finger of a hand of the user can engage.
- the end piece 13 of the first receiving member consists of a generally hollow cylindrical sleeve 14 open at its two ends, provided with an external end flange 15.
- the external peripheral face 16 of the sleeve 14 has an external diameter suitable for being axially forced into the central opening of the ring 12 until the flange 15 bears against the ring 12.
- the inner face 17 of the sleeve generally cylindrical or slightly conical, has a diameter suitable for receiving axially at low clearance the end of the user's ring finger.
- the angle A is advantageously between 10 and 20 degrees approximately, in the direction shown in the figures, direction in which the the opening provided with the flange 15 is further from the blades 4 and 8 than the opening opposite the flange 15.
- the appropriate angle A is obtained when the end piece 13 is positioned in the ring 12 in a preferred axial orientation, this orientation can be materialized by respective benchmarks or any other means such as engaging parts.
- the ring 12 of the first articulated element 1 is pivotally mounted about a longitudinal pivot axis 19 of the first articulated element 1, so as to freely orient the ring 12 around said longitudinal pivot axis 19.
- the ring 12 of the first receiving member 7 is connected to the first corresponding branch 6 by an articulation 30 with a longitudinal pivot axis 19.
- the same end piece 13 can be introduced indifferently by one or the other of the two faces of the ring 12, defining respectively a right-handed tool and a left handed tool.
- the inner surface of the sleeve 14 may advantageously include irregularities such as ribs and grooves, cells, bosses, favoring the ventilation of the skin in contact with said sleeve.
- the second receiving member 11, mounted on the second articulated element 2, comprises a longitudinal end portion 23 of the second branch 10, associated with a transverse support structure 24 developing substantially in the pivot plane of the articulated elements 1 and 2 opposite the first articulated element 1, as shown in FIG. 1.
- the support structure 24 comprises a concave support face 124 oriented towards the free end 26 of the second branch 10.
- the support structure 24 shown is a rod, one end 25 of which is integral with the second branch 10 of the second articulated element 2, said rod being curved in an arc according to a concavity turned towards the free end 26 of the second branch 10, and along a radius greater than the mean radius of an inch of user.
- the support structure advantageously forms an arc of approximately 90 degrees.
- the distance separating the support structure 24 from the intermediate common axis 3 is less than the distance separating the ring 12 from the same intermediate common axis 3.
- the user can hold the tool by engaging the end of his annular in the end-piece 13 of the ring 12 and by engaging the end of his thumb in abutment both on the external face of the longitudinal end portion 23 of the second branch 10 and on the concave face of structure support 24 closest to the free end 26 of the second branch 10. It is important that the thumb can be supported on the concave face of support structure 24 furthest from the blades 4 and 8, and not on the front side of support structure 24 closest to the blades 4 and 8.
- this latter arrangement does not allow appropriate holding of the tool when maneuvering the blades 4 and 8 for cutting, and generates a torque of rotation the tool in the anticlockwise direction in FIG. 1, a torque which must then be compensated by an additional effort from the other fingers.
- a particularly simple solution for adjusting the longitudinal position of the support structure 24 is to provide a set of several removable and interchangeable support structures 24, each comprising a base which is fixed in a receptacle of the second branch 10 of the second articulated element 2.
- the support structure rods 24 are offset longitudinally with respect to each other on their respective bases. The user can thus choose the support structure 24 most appropriate to the morphology of his hand, and fix it at the free end of the second branch 10.
