Definitions

  • the invention relates to a knife, as has become known according to the preamble of claim 1 by US-PS 28 62 296.
  • short knife blade should be understood to mean a short trapezoidal blade, rectangular blade or hook blade - at least not a strip-like snap-off blade.
  • a short knife blade is therefore used, which mainly consists of strip steel and is generally no longer used after becoming blunt, but is replaced by a new knife blade.
  • the invention has for its object to design the known knife so that a knife blade change in a simple manner without significantly delaying the operation Manipulations can take place. This object has been achieved in accordance with the characterizing part of patent claim 1.
  • the knife according to the invention is characterized in that the slider part or a part thereof can be easily loosened and removed through the outwardly open slider longitudinal slot when the knife blade is retracted (here the knife blade is completely accommodated in the handle body), so that the knife blade is free.
  • the blunt knife blade can be exchanged, which can be exchanged for a new knife blade after it has been removed through the slider longitudinal slot, which can also be inserted through the slider longitudinal slot into its mounting position and then or subsequently through the slide part or through a part the same is positively and releasably locked to the slide part.
  • the longitudinal slot has a width corresponding to the knife blade and is arranged on a broad side of the handle body, the slide part, which is locked in a removable and form-fitting and releasable manner, forms a cover that lies against the outer broad side of the blade.
  • This cover can be easily loosened and, if it is hinged on one side, for example, can be pivoted out so that the blunt knife blade is exposed for replacement by a new one.
  • the easily detachable locking of the slide cover can take place in various ways, preferably by snap locking means, which bring about a releasable locking of the cover on the actual inner slide part.
  • a second basic embodiment according to the invention essentially consists in that the form-fitting, easily releasably locked slide part can be removed together with the knife blade together with the knife blade through a slot provided on a handle body narrow side and extending in the longitudinal direction of the handle body.
  • a particularly preferred embodiment of this second basic embodiment according to the invention consists in the fact that the slide part with the knife blade can be pivoted out in the retracted rest position of the knife blade about a pivot pin extending transversely to the broad grip body surfaces.
  • a knife is shown overall with the reference number 10 (Fig. 1-3) or 10a (Fig. 4).
  • Each knife has a substantially hollow handle body 11 (Fig. 1-3) or 11a (Fig. 4), which consists of two handle halves 12 (Fig. 1-3) or 12a (Fig. 4).
  • a slide longitudinal slot 13 is provided on a broad side (ie on a longitudinal handle half 12) of the handle body 11, which extends through a handle half 12 over its entire thickness.
  • the width b of the Slider longitudinal slot 13 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 lower half of the handle shell 12, which is otherwise not visible in FIG the knife blade 14, however, is not guided directly but by means of an inner slide guide part 17 so as to be longitudinally displaceable parallel to the longitudinal axis x of the handle body.
  • the knife blade 14 is in its cutting position, i.e. the inner slide part 17 is shifted completely forward to the cutting side denoted by S, a slide cover 18 of approximately V-shaped design in the front abutting a correspondingly designed stop A of the longitudinal slide slot 13.
  • the knife blade 14 is held releasably locked in its advanced cutting position between the inner slide part 17 and the slide cover 18, 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 is located together with the inner slide part 17 and the slide cover 18 in the retracted rest position according to FIG. 3. Since the slide cover 18 is connected to a bracket part 23 via a film hinge 22 and this in turn on the inner part Slider part 17 is held, the slide cover 18 can be released in the pivoting direction u from the connection of the snap locking means 21, so that the knife blade 14 can be removed to the outside through the wide slide longitudinal slot 13 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 parts 17, 18 - the latter with the bracket part 23 - suitably consist of a suitable plastic, that is, they form plastic injection molded parts.
  • the two handle shell longitudinal halves 12 can optionally represent plastic injection molded parts or metal die cast parts.
  • the embodiment according to FIG. 4 has a slide longitudinal slot 13a on the upper narrow side of the handle body 11a. 4, the knife blade 14 is in its operating position advanced toward the cutting side S.
  • the slide assembly 26, 27 is such that the knife blade 14 in the retracted rest position of the slide 26 together with the latter by one of a handle shell longitudinal half 12 inwardly projecting pivot pin 27 can be pivoted outwards out of the slide longitudinal slot 13a in accordance with the pivoting direction v, as indicated by the dashed partial representation in FIG. 4.
  • the knife blade 14 In the pivoted-out position (not shown), the knife blade 14 can be pulled off the side of the centering pin 28 and replaced by a new one.
  • the slide or the slide part 26 form an elongated hole 29 which extends in the longitudinal direction x of the handle body and in which the pivot pin 27 is received.
  • the end 30 of the elongated hole 29 facing away from the cutting side S rests on the pivot pin 27 in the cutting position 14 of the knife blade shown.
  • the one handle shell longitudinal half 12a shown folded down forms a short guide groove 31 which extends in the longitudinal direction x of the handle body and which is open at its two ends in an offset arrangement to the pivot pin 27.
  • a slide-like, strip-like guide projection 33 which partially covers the rear end of the knife blade 14 at a distance, engages longitudinally and slidably. If the slider 26 with its slot 29 moves completely away from the cutting side S to the rear and the pivot pin 27 abuts the front end 32 of 29, the strip-shaped guide projection 33 is already outside the guide groove 31, so that the pivoting movement of the arrangement 26, 14 in direction v can be initiated unhindered for the exchange of the knife blade 14.
  • the slide-side actuating handle 34 is connected to the inner slide part 17 via a connecting web 35.
  • the entire slide is suitably made of plastic, so it forms a plastic injection molded part.
  • the handle shell longitudinal halves 12a can either form plastic injection molded parts or metal die cast parts.
  • the slide handling surfaces are each designated 36.
  • the end of the guide groove 31 facing away from the cutting side S is designated by 37.
