Definitions

  • the invention relates to a knife with at least a protective part according to the preamble of Claim 1.
  • a knife is in the DE 31 16 354 A1 described.
  • the knife known from DE 31 16 354 A1 has become particularly extensive as a cardboard cutting knife proven in practice.
  • the well-known knife is felt however in need of improvement because the protection pin also accidentally in its release position is displaceable and thus e.g. Hand injuries can be caused. For example then happen when a worker put the knife in the pocket of the work suit for example, one that can be opened with both hands Handle cardboard. Reaching in afterwards in your pocket it is then quite possible that the protective pin when gripping the knife from his Guard position moved away so that the hand accidentally a cutting contact with the partially exposed Knife edge suffered.
  • a knife of another type DE 34 33 286 A1 discloses a cross-section U-shaped protective part relative to a knife blade to move longitudinally and this Relocation movement with an actuation button bring about.
  • the one described with the above known knife according to DE 31 16 354 A1 connecting Advantage that the protective pin is alone by pressure contact with the material to be cut into its release position can be moved is with the knife not given according to DE 34 33 286 A1.
  • Knife according to DE 31 16 354 A1 is the Invention based on the object, the protective function to improve the protective part of the known knife.
  • this object solved in that the protective part an actuation locking device is assigned, which means an operating button in the protective position of the Protective part can be locked and unlocked and that the protective part is in its protective position is locked when the control button is not pressed.
  • Embodiment causes depression, for example the operating button unlocks the Protective part in its advanced protective position, so that the protective part in when the button is depressed its release position exposing the knife edge can be pushed back.
  • the actuation lock is activated, which only allows the protective part to be pushed back, when the control button is depressed, i.e. operated becomes.
  • Embodiment also moves the protective part depressed control button and at Interrupt the cutting work or at the end the cutting work in its advanced protective position back, but remains in spite of it depressed control button in its by the Actuation locking device effected locking position.
  • the protective part can be removed from this locking position only with repeated conscious actuation, i.e. by Release the control button and press it again the control button, from its locked position be freed.
  • Protective part can be the pen shape already described or a bow shape or a shield-like training have, the latter in a known manner for example against spring return force from their Protective position can be placed in a release position can.
  • the protective part can be used in a known manner as a double swivel plate be trained which during a protective gap for its protective position the knife blade forms.
  • the one-sided peripherally mounted double swivel plate swivels this against spring return force relative to Handle body upwards, so that the knife edge for Carrying out the cutting work from the protective gap can come out.
  • Knife is that Protective part with at least one rigid protective pin each forms a rigid pin area, which forms extends along the edge of a knife blade and which is parallel to its longitudinal central axis in one Tranglator sliding guide space of the handle body Slidably held and against the spring return force can be inserted into the handle body, that the actuation locking device one with the Handle body fixed, approximately transverse to the longitudinal central axis of the pin area extending bolt stop surface has that within the handle body on Pin area is held a latch, which the Bolt stop surface engages with a bolt surface and the pen area in its protective position blocked, and that the locking surface by means of the control button to its unlocked position is relocatable.
  • the latch forms a pivotable on the pin area stored pawl.
  • the direction of translation is of the pin area in the swivel plane of the Jack or parallel to this.
  • a tax recess In this tax recess the pawl can head towards the tip of the knife penetrate in the immersion direction while the Pin area is in its protective position. In order to the pawl in this position its locking function can perform, i.e. with its bolt surface can reach behind the bolt stop surface are Immersion depth of the pawl and that of the immersion depth rectified depth of the tax recess each other Voted.
  • the invention also becomes a lock the pen area in its protective position, if the control button after the Cutting work and the associated pressure relief inadvertently operated the pen area becomes.
  • Each knife 10 has a handle body 11 and a knife blade 12 releasably fastened therein, the in the embodiments shown as a trapezoidal blade is trained and therefore a straightforward Cutting edge 13, one inclined to the handle longitudinal axis y extending straight end face 14 and in front a knife blade tip 15 has.
  • a safety bar 16 has two in parallel spacing pin regions 17 arranged relative to one another, whose approximately piston-like inner ends 18 in a guide channel 19 in the push-out direction x and z translationally movable in the insertion direction are.
  • All the embodiments shown have one Actuation locking device, which by means of a Control button 27 is actuated.
  • the knife 10 can alternatively with two different actuation locks be equipped.
  • the first variant is that the depressing the control button 27 unlocking of the safety bar 16 in its advanced Location (Fig. 1, Fig. 5) causes the safety bar 16 with the key 27 pressed in the direction of z can be pushed back.
  • the safety bar 16 ends below its two Pin areas 17 with the part-circular arches 21, the leading ends 22, the free ends 23 and finally the strap bridge 24.
  • the guide channels 19 for the two pin areas 17 share a guide channel block 28 and on a stop block 29.
  • the bearing bracket 30 is supported at its free end in a storage solution 31 a pawl K, which according to Kind of a two-armed lever is formed and a latch arm 32 with a jack head 33 and also has a reset arm 34, which by means of a compression spring held in the bearing bracket 30 35 in the direction of incidence or locking v Jack K is reset loaded.
  • the pin areas 17 are for the purpose of simplification the drawing shown interrupted, as well a tension spring 36, the lower end of which is fixed in the handle body Hook 37 and its upper end in one held on the bearing bracket 30 fixed hooks 37A is.
  • the tension spring 36 accordingly represents the spring restoring force F represents which regarding the pin areas 17 acts in the direction of ejection x.
  • control button 27 which is an operating handle 38, a control body C is in one piece educated.
  • the control body C forms a control recess 39 with a control surface 40, which with a counter control surface 41 on the jack head 33 of the pawl K cooperates.
  • the jack head 33 also forms a locking surface 42, which is intended with the bolt stop surface 43 of the stop block 29 cooperate.
  • the jack head 33 is immersed with an immersion depth ET into the control recess 39. Because the immersion depth ET is less than the depth AT of the tax recess 39, it is ensured that the transition 5 in the locked state 4 a barrier-free locking between the latch-side locking surface 42 and the bolt stop surface 43 fixed to the handle housing can.
  • the one-armed lever 46 forms one to the jack head 33 control projection 48.
  • the safety bar 16 is by means of the actuation locking device H in its The protective position locks and supports itself the bag surface E.
  • the latch surface 42 of the pawl K is locked on the bolt stop surface 43 of the stop block 29.
  • the control spring 45 ensures a safe immersion of the jack head 33 into the control recess 39.
