Definitions

  • the present invention relates to a cutter with a monobloc blade holder, the blade can be fixed in place or released for a simple change pressure.
  • the object of the invention is to propose a blade holder structure simple, effective and requiring no disassembly for the installation or blade change.
  • the subject of the invention is a cutter with a monobloc blade holder with fixation-release of the blade by pressure, characterized in that said blade holder is made by molding a semi-rigid plastic material and comprises two substantially flat shells folded down opposite one of the other, connected by a thin bridge and defining between them a housing of receiving a blade open at least on one side, one of the parts having on its internal face a projection capable of penetrating a hole of the blade so as to hold it captive in said housing and being, at the neighborhood of the latter, deformable by pressure so, by leverage, to move said projection away from the opposite face of the other shell, thus allowing the free passage of the blade out of its housing.
  • said projection is formed in the vicinity of the free end of a tongue forming all or part of one of the two blade holder shells, said tongue being capable of tilting around a fulcrum provided on the second hull facing the central area of the tongue, when it is pressed on it, between said point support and the foot of the tongue, in the direction of said second shell.
  • Such a device is particularly simple and inexpensive to produce since it comprises a single molded part which, by simple deformation by pressure of one inch for example, allows the establishment or extraction of a conventional thin blade and by releasing said pressure, returns to normal position for using the cutter, the blade being correctly and firmly wedged and held captive in its housing by not leaving protrude outside than the fringe carrying the cutting edge.
  • the cutter shown in the drawings consists of a single piece in semi-rigid plastic injection molded comprising two shells 1a and 1b connected by a hinge constituted by two thin bridges 2. Au demoulding, the shells 1a, 1b are substantially in the same plane and side by side and are then folded back against each other, the articulation being made at right the connecting hinge 2, being kept in this position, as a bivalve, by any appropriate means (not shown) such as welding or clipping by pins and receiving holes.
  • the shells 1a, 1b thus folded back form a blade holder 1 receiving a conventional rectangular blade 3 of the type illustrated in FIG. 3.
  • This blade 3 has a cutting edge 4, a central oblong hole 5 and its other edge is encased in a metal cover 6.
  • the blade holder 1 has, opposite the axis of the hinge 2, an edge parallel 7 which extends beyond the fringe carrying the cutting edge 4 of the blade 3.
  • the blade 3 is held captive between the shells 1a, 1b, in a housing 8 defined in the area adjacent to the edge 7.
  • This housing 8 includes a part capable of accommodating the cover 6 of the blade, connected to the front edge 7 of the cutter by a slot 8a, delimited between the two shells 1a, 1b and of thickness very slightly greater than that of the blade 3.
  • the housing 8 and the slot 8a open on the two lateral sides of the cutter as can be seen in Figure 2, allowing you to thread the blade 3 laterally to the cutter, on one side or the other.
  • the nipple 10 is carried by a rectangular tongue 11 cut out in the middle zone (FIG. 1) of the upper shell 1a, with from the free edge 7.
  • a fulcrum 14 such as a pressure P (FIG. 4) exerted for example using a thumb on the part of the tongue 11 between the fulcrum 14 and the foot 12 of the tongue in the hollow 13 made, by leverage on point 14, raise the nose 11a of the tongue in R and therefore move away from the shell 1b the blade locking pin 10.
  • the tongue 11 is only deformed by this pressure so that, from on either side of the tongue, the zone of the shell 1a in the vicinity of the edge 7 remains in place by maintaining the slot 8a.
  • the blade 3 remains retained between the shells 1a, 1b and is not driven by the nose 11a of the tongue.
  • nipple 10 It is thus normally released by the nipple 10 and can be extracted from its housing, laterally, on one side or the other of the cutter, for a blade change for example.
  • the device By releasing the pressure P, the device returns elastically, due to the nature of the plastic material used, in the position (figure 3) of locking of the new blade 3 by penetration of the stud 10 in the hole 5.
  • the housing (8, 8a) receiving the blade 3 is suitable for type of blade which can vary, this housing can also be entirely conformed in the non-deformable shell (1b) and possibly provided with means for blocking the movement of the blade perpendicular to its plan.
  • the hinge (2) connecting the two shells 1a, 1b and whose interest is obvious since it allows the realization by a single mold of a blade holder monobloc by simple self-centered folding of the two shells, can of course be performed in another way with one or more elements.
