  • the knife has a blade which is rotatably connected to the handle.
  • a slot is provided in the handle, into which the blade is screwed or folded can be. If the blade is folded into the handle, it can be folded out.
  • the knife according to the invention advantageously has a locking means by which the Blade can be locked or unlocked when the blade is folded into the handle is.
  • a locking or unlocking in the aforementioned sense exists if this occurs manual actuation of the locking means is possible.
  • the locking means can manually brought into two positions. In the first position is the folded one Blade locked. If the locking means is then suitably operated manually, it is The lock is then released. The blade can then be folded out of the handle without having to act on the locking means again.
  • a locking means in the aforementioned sense can in particular as Child lock act.
  • the cutting edge becomes sharp Side of the blade, covered by the handle.
  • the cutting edge is then no longer from the outside accessible.
  • By then locking this end position of the blade one becomes additional protection against improper handling.
  • An improper one Handling and associated injuries are particularly to be feared if a sophisticated knife falls into the hands of small children. Is that folded in The blade is then locked so that a small child cannot easily remove the blade fold out and injure yourself or others afterwards with the sharp edge inflict.
  • the aforementioned locking means for the Locking of the folded blade an externally accessible, rotatable bolt, which is in the handle of the knife.
  • the bolt has a recess.
  • the blade also has a recess.
  • the two recesses are so on top of each other coordinated that the recess of the bolt is in the recess of the blade, when the blade is folded into the handle. Furthermore, the two recesses are like this ensure that the folded blade either locks by turning the bolt or unlocked.
  • the design of the aforementioned locking means is easy to manufacture. Further requires the pin to rotate, especially if it is only a small one Diameter has a certain manual skill to turn it. There one Certain manual dexterity is required for unlocking it Toddler regularly not or hardly possible, a locked, folded blade closed Unlock. The child lock then works particularly reliably.
  • a fixing means is provided, which fixed the bolt in such a way that a force greater than that must be applied to unlock than the force to be used for the rotation of the bolt. In this way the Protect bolts from accidental rotation. The intended backup will be like this further improved.
  • the fixing means is realized in a particularly simple manner by a spring, which in one Groove snaps into place when the blade folded into the handle is locked.
  • the bolt points then, for example, the groove.
  • the corresponding spring is located expediently inside the recess of the blade. The location and size of tongue and groove are matched to one another in such a way that they are in the locked, folded state of the Snap the blade together.
  • the bolt is from the outside accessible, but is recessed in the handle. This means that he is not from the Handle protrudes or protrudes. There is then a separate one for turning the bolt Tools required. A small child can only operate the bolt if it is this tool is available. The intended child lock will continue improved.

So can an adult use a coin from his wallet to get one folded Blade either lock or unlock. A coin stands for an adult regularly available immediately. Thus the actuation of the locking means is not This prevents the desired tool from not being used at the crucial moment Available. Since a toddler does not regularly have a coin, this is security guaranteed.
  • the knife comprises a bracket, which is rotatably connected to the handle and slidably connected to the blade.
  • the bracket covers with the blade folded in, the knife's trade. Under the knife trade the area understood by the rotatable connection between the blade and handle is formed. When the blade is unfolded, the bracket is on the side of the knife that is opposite the cutting edge of the blade.
  • the protruding bracket serves as a thumb rest and as Barrier to. If the knife is held by the handle, z. B. with the thumb pressure be exerted on the bracket and in this way also on the blade. The coat hanger prevents the thumb from sliding along the blade. Slipping is avoided and thus a possible risk of injury.
  • the bracket extends to the side of the blade to the slot.
  • the bracket has a bolt that leads into the elongated hole. So is on the one hand a connection between the bracket and the blade is created. on the other hand the bolt can be moved along the slot so that the connection between Bow and blade can be moved within the meaning of the invention.
  • the slot is attached so that the blade can be folded into the handle unhindered without doing so the blade attached bracket to be blocked.
  • the maximum width of the bracket advantageously corresponds essentially to the width of the handle.
  • the width of the handle is understood to mean the extent of the handle, which according to the section Fig. 4 is shown.
  • the width of the bracket is adapted to the handle, so a nice one To bring about appearance, to provide a safe slip protection for the thumb and reliably protect against dust when the blade is folded.
  • a further locking means is provided which the blade in the extended position locked.
  • the blade has a recess in particular on, in which a locking element engages, which is connected to the handle.
  • the Blocking element is pressed into the recess by means of spring force.
  • an adjusting means is provided with which the bias of the spring can be changed.
  • the actuating device can consist of a bolt with a recess.
  • the spring presses against the recess.
  • the bolt for adjusting the spring force is recessed in the handle and accessible from the outside. This bolt is also preferably rotated with the aid of an aid. Accidental Adjustment of the spring force is avoided.
  • the bolt is like that in particular designed that it can be rotated with the help of a coin. He points to the End, which is accessible from the outside, a suitably large slot.
  • Fig. 1 shows a knife with a blade 1 and a handle 2.
  • the blade 1 is in the handle into it worked. Shells of handle 2 are then to the left and right of the blade.
  • the The cutting edge of the blade is recessed in the knife handle.
  • a bolt 3 has a recess. This area is located in a recess in the blade.
  • the recess of the blade is designed in such a way that turning the bolt 3 prevents the bolt from turning Can leave recess.
  • the locked state is shown.
  • the rotatable connection between blade 1 and handle 2 is made with the help of a bolt 17 enables that passes through the handle and the blade.
  • the area at bolt 17 is called business.
  • This area is in the folded state by a bracket 8 the blade covered to the outside.
  • the bracket 8 thus serves as dust protection.
  • the bracket 8 is on the one hand, rotatably connected to the handle 2 in the case of a bolt 18.
  • At the other end of the This bracket is shaped so that it extends to an elongated hole 10, which is in the Blade 1 is located.
  • a bolt 11 of the bracket 8 extends into the elongated hole 10. The bolt 11 can thus be moved within the slot. So that is a sliding Connection between bracket 8 and blade 1 created. Despite the connection between Blade 8 and blade 1, the blade 1 remains movable, d. H. it can be folded in and out become.
  • Fig. 2 shows the knife in the opened state of the blade.
  • Handle 2 and blade 1 form in essentially a straight line.
  • a strip-shaped element 19 extends in the essentially along the handle 2. It represents a spring element.
  • the strip-shaped Element is rotatably connected to handle 2 via a pivot point 20. It ranges from open end of the handle to the end of the handle 2, in which the blade 1 rotates with the handle is connected.
  • the strip-shaped element 19 has one end protruding blocking element 12. This blocking element snaps into a recess 13 in the blade when the blade is fully opened. In this way the Blade 1 locked when extended. Through a suitably running slot the strip-shaped element 19 functions as a resilient element 16.
  • This resilient element 16 presses against a bolt 15 which is located near the open end of the handle 2 located.
  • the resilient element is preloaded. This ensures that protruding blocking element 12 by spring force in the recess 13 of the blade is pushed in.
  • the strip-shaped element 19 comprises a serrated area 14 which is accessible from the outside. This area 14 serves as a button that is pressed down in order to lift the blocking element 12 out of the recess 13 of the blade.
  • the Button 14 must be pressed down against the spring force of the resilient element 16.
  • the bolt 15 is provided with a recess. The resilient element presses against it Recess of the bolt 15. If the bolt 15 is rotated, the preload becomes of the resilient element 16 adjusted. It is thus possible to vary the force with which that button-shaped element 14 must be pressed down to the blade in the unfolded Unlock state.
  • an elongated hole 21 is provided.
  • a bolt 22 passes through the elongated hole 21. hereby becomes the possible rocking movement of the strip-shaped element 19 about the pivot point 20th guided around on the one hand and on the other hand blocked in two end positions. An end position is reached when the bolt 22 reaches one end of the elongated hole 22.
  • the blade 1 has a recess 5.
  • the recess 5 initially leads in essentially vertically into the blade and then continue to the right.
  • the bolt 3 has a recess 4. At this point, the bolt 3 is essentially in section designed semicircular. If the blade is folded in, the bolt 3 arrives in the Area of the recess in a suitable position into the recess 5. Will the Bolt 3 is then suitably rotated so that it reaches the area of the recess, that leads to the right. The blade 1 is then blocked in the folded state, as already 1 was seen.
  • bracket 8 protrudes when the blade is out the handle has been folded out completely. If the knife is held on the handle 2, it forms the bracket 8 protects against slipping of the thumb in the direction of the blade. Since the Bracket 8 is significantly wider than the blade 1, this is also significantly better as a support for a thumb, so as to force the blade towards an object to be able to be cut, for example. Especially for optical reasons the bracket 8 corresponds to the width of the handle. It is enough to form a good circulation however, from the fact that this is only significantly wider than the blade 1. Of course the bracket can also be wider than the handle.
  • Fig. 3 the depressing of the button 14 is shown.
  • the bolt 22 finally arrives to one end of the elongated hole 21.
  • the button 14 can then no longer be pressed down.
  • the blocking element 12 is thus lifted out of the recess 13 in the blade 1.
  • the Blade 1 can then be pivoted in the direction of the handle 2. this happens for example by pressing against the bracket 8.
  • FIG. 3 clearly shows how the resilient element 16 now compared to that in Fig. 2 shown situation has been biased more.
  • the bolt 15 is in this case rotated so that the bias of the resilient element 16 is almost maximum is. If the bolt 15 is rotated by approximately 180 °, the area of the recess will follow below.
  • the resilient element 16 is relaxed accordingly.
  • the force required to Depressing button 14 is reduced accordingly.
  • Fig. 4 shows a section through the knife with the blade 1 and the handle 2 that in particular the bolts 3 and 15 are shown in section.
  • the bolt 3 is the bolt that is used to lock the child. This is accessible from one side of the handle, but recessed in the handle so that it does not protrude from the handle. Accessible from the outside the bolt 3 has a slot 23. A coin can be inserted into this slot to turn the bolt 3.
  • the bolt 15 is designed as an actuating element for the resilient element 16 serves.
  • the bolt 15 is also recessed in the handle so that it does not come out of it protrudes. It is accessible from one side of the handle. It points from the accessible side seen here a slot into which a coin can be inserted. With the help of a Coin, the bolt 15 can thus be rotated to adjust the keystroke is required to depress button 14.
