Definitions
- the invention relates to a knife according to the Preamble of claim 1.
- DE 36 22 342 A1 discloses such a safety knife, a so-called cardboard knife, known which is used for cutting packaging boxes becomes.
- a translatable blade carrier is against a restoring force, namely against a spring restoring force, by means of an actuation area, which represents a push handle handle the knife housing can be extended and into the cutting position the interchangeable steel blade he picked up movable.
- an actuation area which represents a push handle handle the knife housing can be extended and into the cutting position the interchangeable steel blade he picked up movable.
- the invention has the object based on the well-known knife in terms of its Improve safety function.
- the invention solves this problem in that the Operating handle from one relative to the blade carrier movable separate actuating part is formed, which counter to the extension movement of the blade carrier with a separate restoring force, e.g. with a separate spring restoring force, is loaded that Blade carrier and actuating part in their starting position by a primary coupling element of the actuating part or the blade carrier and by a corresponding secondary coupling element of the Blade carrier or the actuating part only in the direction of extension the blade carrier is motion-coupled to be carried along, however in the entry direction of the blade holder are disengaged from each other that the movement of the Operating part limited in the sense of extension of the blade carrier is, and that the blade carrier an additional Relative movement in the extension direction is permitted, which the two coupling elements out of engagement with each other added.
- a separate restoring force e.g. with a separate spring restoring force
- Safety knife at first essential, that the operating handle from a relative to Blade carrier movable separate operating part is formed.
- Both the blade carrier and the separate one Actuating part are in the invention Knife with a separate force, preferably with a separate spring force, in their starting position reset load. That is the invention Actuating part against the extension movement of the Blade carrier resiliently loaded with a separate spring force.
- Safety knife Another remarkable peculiarity of the invention Safety knife is that Blade carrier and actuator in their reset or retracted starting position a primary coupling element of the actuating part or of the blade holder and by a corresponding secondary Coupling element of the blade carrier or Actuating part only in the direction of extension of the blade carrier are coupled with movement, but in the direction of entry the blade carrier out of engagement with each other are.
- This additional relative movement is e.g. to used, the secondary coupling element of the blade carrier out of engagement with the primary coupling element to move the actuating part, whereby the first existing, one-sided in the direction of extension of the blade carrier existing motion clutch is disconnected.
- the definition "the movement of the operating part in the sense of extension of the blade carrier” is to be defined that the shape, shape and direction of this movement are indifferent if only the movement of the actuating part the movement of the blade carrier in the direction of extension causes.
- a simple design of the knife according to the invention is in any case due to a translational rectilinear To achieve movement of the moving part.
- a variant of the knife according to the invention can in a translationally curved movement of the actuating part consist.
- the switching movement can be prepared that the trajectories of the two Coupling elements or the movement paths of blade carriers and actuating part including those assigned to them Coupling elements run differently.
- An advantageous way to prepare the switching movement consists in the use of a backdrop control, which in particular the actuator and the Knife housing can be assigned.
- At least one slot or at least one Guide groove with a respective assigned guide pin provided is at least one slot or at least one Guide groove with a respective assigned guide pin provided, the longitudinal course of the slot slot or the guide groove in the direction of the actuating part with respect to the direction of extension of the blade carrier diverges.
- One embodiment can be that the link slot or the guide groove along one arranged transversely to a main surface of the knife blade Level extends.
- Another advantageous embodiment e.g. in that the backdrop slot or the guide groove along an in or parallel arranged to a main surface of the knife blade Extend level.
- Another embodiment variant according to the invention consists in that the assigned to the actuating part Link control two link slots or guide grooves with two corresponding guide pins for Has generation of the switching movement. Is expedient the respective link slot or the guide groove formed by the knife housing while the respective Guide pin is formed by the actuating part.
- a particularly essential embodiment of the invention is that the switching movement to Preparatory separation of the two coupling elements initially just a potential spring energy generated that only in the course of the additional relative movement of the blade carrier effective in the direction of extension becomes.
- the two coupling elements disengaged so that the potential previously generated Spring energy is capable of a separating movement bring about, at least on a coupling element relates and both coupling elements from each other distant.
- the distance is done in such a way that those stored by the blade carrier and operating part two coupling elements move past each other can, if the cutting reaction force in one reduced to such an extent that the spring return force in is able to retract the blade carrier into its Starting position to move.
- the Distance between the two coupling elements also Possibility to create that regardless of position the blade carrier the released actuator of the spring restoring force assigned to it in its starting position can be moved back.
- the pressure transmission element (or more generally: Power transmission element) can, for example, by a link-controlled and / or spring-loaded jack (Pressure pawl or pull pawl) are formed, which too Start of the additional relative movement of the blade carrier disengaged from the recess in the direction of extension becomes. Basically, it is the same whether the transmission element the actuating part or the recess Blade carrier or in reverse the blade carrier or are assigned to the actuating part.
- a simple safe uncomplicated design is given that the pressure transmission element a one side clamped buckling bar forms its movable free end the lead as primary or secondary Coupling element, which with a Recess as a secondary or primary coupling element interacts.
- the invention also has the Possibility provided that already in the free buckling bar a particularly effective spring force integrated is by making the free buckling bar from a spring metal, in particular from spring steel.
- the Buckling bar the blade carrier or the actuating part is integrally formed and in particular from one plastic has elastic properties.
- a particularly practical one according to the invention Embodiment is that blade carriers and Actuator side by side in one to a main surface the knife blade parallel or inclined plane are arranged.
