Definitions

  • the invention relates to a knife with a essential hollow handle body for receiving and guiding a slide according to the preamble of Claim 1.
  • a knife is in the DE 36 22 343 C2 described.
  • the knife known from DE 36 22 343 C2 has a slide in the handle body. On the handle body has its two broad sides Longitudinal recesses that the slide with Actuation projections penetrated. On a broadside an actuating projection forms a knife blade cover part, that with a film hinge on one Knife blade receiving part is articulated, that too is part of the slide.
  • Protrusions protruding from the receiving surface reach through the knife blade centering and securing the position and also serving as locking pins, which engage in locking holes in the folded cover part to to lock the cover part and the receiving part together.
  • the knife blade is in her Cutting position in which it is with its front Area through a knife blade passage slot on the handle body side protrudes through.
  • a return spring displaces the Knife blade indirectly via the slide in your located inside the hollow handle body Rest position.
  • the retracted rest position of the knife blade provides the knife according to DE 36 22 343 C2 at the same time a certain position of the receiving part, in which after unlocking and after a relative movement (Opening the cover part) between cover part and Receiving part the knife blade unhindered from Receiving part is removable.
  • short Knife Blade is intended to be a short one, for example Trapezoidal blade, rectangular blade or hook blade understood become. So short knife blades are used, which are mainly made of steel strip and in generally no longer used after becoming stumped, but are exchanged for new knife blades.
  • Knife of the narrower type (DE 36 22 343 C2)
  • the Invention based on the object, the known knife to further develop that with different Knife types an easy to replace the knife blade can be achieved.
  • this object solved in that the cover part and receiving part in two mutually parallel planes are movable relative to one another are, and that the unlocked receiving part together with the knife blade held by the receiving part by a Removal slot from the handle body into one Removal position of the knife blade can be guided to the outside.
  • cover part and receiving part also a Basically including pivoting movement, in two mutually parallel planes movable relative to each other are.
  • cover part and receiving part also a Basically including pivoting movement, in two mutually parallel planes movable relative to each other are.
  • the receiving part which is sufficient for the knife blade by means of at least one projection or the like. secures positively on the receiving surface, together with the knife blade away from the cover part through a Removal slot out of the handle body to the outside guided and then removed the knife blade unhindered become.
  • the invention particularly prefers one Embodiment according to which cover part and Receiving part translationally relative to each other are movable.
  • Guide means for guiding the movement of the cover part and Recording part provided.
  • the guide means be assigned to the cover part and / or the receiving part.
  • a preferred embodiment of the invention the design of the management means is that the guide means of the cover part and / or of the Recording part are formed directly themselves.
  • a knife of overall simple design exists according to the invention in that cover part and Receiving part in the direction of displacement of the slide relative are translationally displaceable to each other.
  • cover part and Receiving part in the direction of displacement of the slide relative are translationally displaceable to each other.
  • other characteristics are advantageously combined, which have a special removal slot for Make knife replacement unnecessary by using the Knife blade passage slot for the cutting position the knife blade also for the passage of Receiving part and knife blade provided removal slot forms.
  • a variant according to the invention provides that the cover part forms the outer contour of the slide, and that the cover part guides the receiving part, which is approximately tongue-shaped.
  • a compact design of a cover and a to have relatively displaceable receiving part Slider is achieved according to the invention in that the Cover part an approximately C-shaped undercut, the Cross section of the receiving part at least partially receiving, in the displacement or axial direction of the Slider has an unchanged internal cross section having interior that forms opposite axial inner surfaces as Guide means one guide channel each forms corresponding countermeasures axial longitudinal ribs of the receiving part exist.
  • a releasable lock between the cover and Receiving part is thereby according to the invention realizes that the cover part one to its C-shaped undercut interior axially open has frame-like extension with a catch, with which interacts with a counter-catch, which is frame-like extension about axially guided locking arm of the Receiving part is formed.
  • the receiving part expediently has one Actuation handle, which in particular the locking arm assigned
  • the invention holds one Embodiment ready, in which the Actuating handle in the wall of the Actuating opening provided on the handle body, e.g. is accessible via an actuation slot.
  • a knife is 10 in total designated.
  • the knife 10 has a substantially hollow Handle body 11, which consists of a lower handle part 12 and consists of a top handle 13.
  • the upper handle part 13 is approximately hood-like trained and by means of two each other opposed stub axle 14, in bearing holes 15 (see FIGS. 2 and 3) are included on Lower handle part 12 hinged.
  • the top handle 13 has one in it Vertex area arranged narrow wall 16 and two themselves adjoining one long side of the narrow wall 16 Side walls 17, of which only one is visible in FIG. 1 is.
  • this Handle upper part 13 On the stub axle 14 facing away from her The free end facing the viewer indicates this Handle upper part 13 has a latch opening 18, which of an approximately push button-like locking pin 19 is reached. If the locking pin 19 counter The spring return force is depressed Bolt opening 18 free, so that the hood-like Handle upper part 13 according to the pivot arrow u around the Pivot bearing arrangement 14, 15 around the lower handle part 12 can be folded down.
  • the knife 10 For holding and guiding a knife blade 20, here a trapezoidal blade, the knife 10 has one Slider 21, which consists of a receiving part 22 for the knife blade 20 and from a corresponding one Cover part 23 is made.
  • the knife blade 20 between a receiving surface 24 of the receiving part 22 and one formed from two partial surfaces 25A and 25B Cover surface of the cover part 23 added.
  • Receiving part 22 and cover part 23 of the slide 21 are along the displacement directions x and z guided translationally relatively movable together. How 4, the cover 23 forms one approximately C-shaped undercut interior 29 for Guide receptacle of approximately T-shaped in cross section Recording part 22.
  • Guide channels 30 formed are guide ribs in shape slidable by axial longitudinal ribs 31 of the receiving part 22 guided.
  • the cover 23 has one of its C-shaped undercut interior 29 axially open frame-like extension 32, which has a latch 33 has, with which a counter detent 34 cooperates, which by an approximately axially guided in the frame-like extension Locking arm 35 of the receiving part 22 is formed.
  • the rest 33 and the counter detent 34 extend parallel to each other and are such with regard to the direction of displacement x inclined that they reach behind like a hook can.
  • actuation extension (actuation handle) 36 At the free end of the locking arm 35 is in accordance with 2 and 3 from the plane of the drawing upwards extending actuation extension (actuation handle) 36 provided, which only when the upper handle part is folded down 13 is accessible.
  • the tension spring 37 shown in FIGS. 2 and 3 is with its tension spring end 38 on the slide 21 and with its tension spring end 39 on the lower handle part 12 releasable attached.
  • Handle body 11 and slide 21 form injection molded parts made of a suitable plastic, e.g. from PA.
  • a knife blade change can be done with the knife 10, starting from the illustration according to FIG. 1, as follows be made:
