Definitions

  • the invention relates to a knife, as has become known according to the preamble of claim 1 by US-PS 28 62 296.
  • the slider longitudinal slot passes through the entire grip body thickness, so that with a simple construction the prerequisite for an actuating handle was created on each broad side of the grip body.
  • the knife equipped according to the invention is equally suitable for both right-handers and left-handers.
  • Both actuating handles carry at least one longitudinal guide bar between them and also take the knife blade between them, preferably releasably.
  • Each knife has a substantially hollow handle body 11, which consists of two handle halves 12 l (left handle half) and 12 r (right handle half).
  • each broad side of the handle body 11 that is to say on the left broad side B l and on the right broad side B r, there is a slide longitudinal slot 13 which covers the entire length of the handle body 11, ie from the left broad side B l to the right broad side B r , enforced.
  • the slide longitudinal slot 13 is divided into two longitudinal slot halves, namely in the left longitudinal slot half H l , and in the right longitudinal slot half H r , as can be seen in particular from FIGS. 4 and 5.
  • the width b of the left longitudinal slot half H 1 is somewhat larger than the width of the knife blade 14 with cutting edge 15, which in the present case represents a trapezoidal blade.
  • the otherwise not visible right handle shell longitudinal half 12 r forms two knife blade guideways 16, which are located at a parallel distance from each other, on which the knife blade 14, however, is not guided directly but can be moved longitudinally parallel to the longitudinal axis x of the handle body by means of a slide designated as a whole is.
  • the knife blade guideways 16, which form guide strips for the slide 17, are described in more detail below.
  • the knife blade 14 is in its cutting position, that is to say the slide 17 is displaced entirely forward towards the cutting side denoted by S, with a slide cover 18 which is approximately V-shaped in the front view on one Correspondingly trained stop A of the left slider longitudinal slot half H l .
  • the knife blade 14 is held releasably locked in its advanced cutting position within the slide 17, as shown in FIGS. 1 and 2.
  • the releasable locking takes place via snap locking means 21, which are shown in broken lines in FIG. 2.
  • the knife blade 14 together with the slide 17, is in the retracted rest position according to FIG. 3. Since the slide cover 18 or the left actuating handle G 1 is in a film hinge 22 on a bracket part 23 and this in turn is held on a slide slide plate 26, the slide cover 18 can be released in the pivoting direction u from the connection of the snap locking means 21. Thus, the knife blade 14 can be taken out through the wide left slide longitudinal slot half H 1 and exchanged for a new knife blade 14.
  • the articulation axis a of the film hinge 22 extends parallel to the transverse axis y of the handle body 11.
  • the slide 17 expediently represents an injection molded part made of suitable plastic, which also enables the film hinge 22.
  • the two handle halves 12 l and 12 r can optionally be plastic injection molded parts or metal die cast parts.
  • the construction of the slide 17 can best be explained on the basis of FIGS. 1-3 with reference to FIGS. 4-6. From Fig. 1-3 it is clear that the slider longitudinal slot 13 passes through the entire thickness of the handle body 11 transversely and that the slider longitudinal slot 13 in turn penetrating slider 17 has such a transverse extent that it is on the left broadside of the handle body B l forms a left actuation handle G l and a right actuation handle G r on the right side of the handle body B r .
  • the two actuating handles G l and G r are arranged mirror-symmetrically to one another with respect to a plane that extends essentially parallel to the plane of the knife blade 14.
  • a special feature of the slide 17 and the guide arrangement on the handle body side is that the handle body 11, namely the right handle shell longitudinal half 12 r , has an inside guide rail 16 on both sides of its longitudinal slot half H r , ie on its upper and on its lower longitudinal side forms (see FIGS. 4 and 5 there each upper representation).
  • the slide part 17 is now divided approximately in one plane between these two guide strips 16, the two slide part regions thus formed, which are each assigned to the actuating handles G l and G r , being detachably or firmly connected to one another.
  • the slide part area with the actuating handle G l is provided with the slide slide plate 26.
  • the slide-sliding plate 26 has two edge-shaped strip-like sliding areas 27 parallel to the plane of the knife blade 14, only one of which can be seen from FIG. 6.
  • the two sliding areas 27 are intended to rest against their parallel strip surfaces 28 of the guide strips 16 (see FIG. 4, upper illustration).
  • the slide sliding plate 26 forms a guide projection 29, which has a lower and upper guide surface 30 running transversely to the plane of the knife blade 14 (only the upper guide surface 30 can be seen from FIG. 6) on a parallel inner one Last area 31 is applied.
  • the slide slide plate 26 forms a receptacle 32 for the knife blade 14 on its broad side facing away from the guide projection 29.
  • the slide slide plate 26 also has one adjacent to its knife blade receptacle 32 Approach 33, which carries male-shaped locking pins 34, which engage in undercut locking holes of the holding bracket 23 (not designated in more detail) in a snap-locking manner.
  • the guide projection 29 has male-shaped locking pins 35 directed towards the right broad body side B r .
  • the locking pins 35 cooperate with latching holes 36 within the right actuating handle G r in a snap-locking manner.
  • the right actuating handle G r can in turn form two edge-like strip-shaped sliding areas 37 (only one sliding area 37 can be seen from FIG. 6) which are parallel to the plane of the knife blade 14 and which rest on the other strip side faces 38 parallel to them, which are shown in FIG. 5 (upper illustration) can be seen.
  • FIGS. 1, 2 and 6 it can also be seen that at the rear end of the slide part 17 facing away from the cutting side S (and detachably within the locking gap between 33 and 34 on a pin not shown in FIG. 6) the front one End 39 of the tension spring 19 is attached.
  • the rear end 40 of the tension spring 19 is fastened within a partially roller-shaped plug body 41, specifically by means of a cross pin 42 shown in dashed lines (FIG. 6).
  • the partially roller-shaped plug-in body 41 passes through both longitudinal handle shells 12 l and 12 r in an adapted to its outer contour handle body side transverse opening 43 with a press fit.
  • the partial-roller-shaped plug-in body 41 forms an extension 45 which delimits the left slide longitudinal slot half H 1 rearward on the left broad side B 1 of the grip body.
  • the extension 45 is axially penetrated by a receiving channel 46 for the tension spring 19 which extends parallel to the longitudinal axis x of the grip body.
  • the extension 45 in turn sits snugly in a receiving slot 47 (the handle shell longitudinal half 12 l ), which represents a narrowed continuation of the longitudinal slot half H l .
  • the two actuating handles G l , G r are arranged in the foremost area (at S) of the handle body 11 and form two handle recesses 48 rising towards the cutting side S.
  • All slide-side snap-lock points - with the exception of the snap-lock point 21 - can also be made non-detachable (e.g. glued) during assembly.
