Definitions

  • the invention relates to hand folding knives, whether or not provided with catch notches.
  • a knife according to the invention therefore essentially consists of a handle and of a blade articulated around an axis of rotation.
  • This articulation is constituted by a hollow socket whose axial opening with an axis perpendicular to the longitudinal plane knife, and whose size is adapted to the size of the link or fixing used, crosses the handle from side to side, and is integral in rotation with the knife blade.
  • This opening may be cylindrical in shape, but of preferably, it will have a flared shape towards the outside for example, in the shape of half torus. This form allows an easier introduction of the link or adapts better at the curvature of the binding (padlock handle, mountaineering carabiners).
  • This operating means consists, for example, of one or two rollers circular.
  • the wheel is externally striated and / or has reliefs to be easily operated with one hand with the thumb or a other finger.
  • the tongue is either elastic or rigid and articulated at their base around an axis of rotation substantially parallel to the longitudinal plane of the knife, and subject to the action an elastic device (spring, elastomer, etc.) acting outwards.
  • the tongue has, in their active part, a flat and elongated shape; the length of the tongue is arranged either in a substantially radial direction, either in a direction substantially tangential to the movement of blade rotation on the handle.
  • the housing end being preferably located on the inner face of the wheel parallel to the longitudinal plane of the knife.
  • buttons - pushers can be provided in the handle, to push the tab towards the outside, and thus allow the rotation of the blade - socket - wheel assembly by report to the handle.
  • the tongue can also be used, the blade of the knife being in the closed position, to create hard friction, preventing accidental opening of the blade.
  • a housing in the form of a trapezoidal prism, similar to that of the catch, is also practiced in the sleeve-wheel assembly, but whose inclination is from 45 ° to 80 ° in order to allow the separation towards the interior of the tongue under a weak force of opening of the blade exerted on the wheel or the blade.
  • curvilinear arrow indicates the direction in which the knife is closed.
  • a knife according to the invention consists of a blade (1) and a movable handle (2) in rotation and with gentle friction, one with respect to the other, around an axis perpendicular to the longitudinal plane (4) of the knife.
  • the blade (1) is sharpened on one sides (5) and has a non-sharp edge (6) on the other.
  • the handle consists of a spacer (7), two plates (8) made of sheet steel and a trim (9) made of wood, horn, plastic or rubberized material, etc. held in place by rivets (10).
  • the articulation between the handle (2) and the blade (1) being constituted by a bush in steel (11) having in its center a hexagonal periphery (12) perpendicular to the axis (3) which fits into a hexagonal opening in the blade (1) of the knife.
  • This sleeve (11) is pierced along the axis (3) with a circular hole (13), and is linked to two steel knobs (14), this connection is made by any known means such as soldering, gluing, crimping, shrinking, etc.
  • the weld (15) can be performed using a laser beam.
  • This tongue (16) as the plate (8) are made of a steel treated after shaping and machining, to give it the required elasticity.
  • the internal surface (14 ') of the wheel (14) has a prismatic housing trapezoidal, whose generatrices are substantially parallel to the direction longitudinal of the knife (20), and whose blanks make an angle of 10 ° with the axis (3).
  • the device is completed by a push button (22) integral with the handle (2) which, by pressing inwards releases the free end of the tongue (16) from the housing (19) of the wheel (14), which unlocks the blade and allows closing knife in the direction of the curved arrow.
  • This provision provides enhanced security against involuntary release or accidental notch.
  • Figure 6 shows a variant of the stopper.
  • the tongue elastic (16) is attached to the inside of the handle (2) and is fixed there, at its base, for example by two rivets (23).
  • the tongue (16) is arranged tangentially relative to the movement of the blade and its free end (24), machined at a bevel with an angle of 10 °, and engages in the housing (19) of the thumb wheel (14).
  • the free end (24) of the tongue (16) is approximately located on a radius passing through the axis (3).
  • the handle can also be in one piece (Figure 8) and be made of metal or plastics, possibly reinforced with short fibers (glass, carbon) and obtained by molding, including the tab (s) (16).
  • the tabs are accessible from the outside of the handle.
  • reinforced plastics and for better elasticity of the tongue, it is preferable that it is reinforced by long fibers, arranged along its length.
