Definitions

  • the invention relates to a diving knife with a knife part which has a knife handle and a knife blade with a first cutting edge and an edge opposite the first cutting edge.
  • Conventional diving knives are completely useless in some situations. For example, if a diver gets caught in a fishing net or in fishing lines, it is hardly possible for him to cut the fixed lines with the diving knife. It is difficult for a diver to free himself with a conventional diver's knife because he needs both hands, i.e. one to hold the diver's knife and the other to hold the object to be cut. In such a situation, however, he often only has one hand available if, for example, he has caught one hand in the fishing net or in the fishing line or has to hold a lamp. With scissors, a diver can cut fishing nets and fishing lines more easily, quickly and safely. The scissors can also be operated with one hand.
  • scissors are not a complete replacement for a conventional diving knife, as a diving knife among other things Has the function of a lever or a weapon.
  • some objects can only be cut with a knife due to their size or location.
  • a diver usually carries all of his equipment on his body and therefore has extremely limited transport capacity.
  • the invention is therefore based on the object of designing a diving knife in such a way that it can be used on the one hand like a conventional diving knife and on the other hand like scissors.
  • the diving knife is characterized by a scissor part which has a scissor handle and a scissor blade with a cutting edge and an edge opposite the cutting edge, which is articulated on the knife part and forms scissors with the knife part.
  • the diving knife according to the invention can be used like a conventional diving knife.
  • it can be used as scissors by means of a usual scissor movement of the scissor part.
  • the scissor blade of the scissor part is advantageously arranged inside the knife blade in the closed state of the diving knife. Therefore, the scissor blade protrudes in the not the closed knife blade, which can be used without disadvantage compared to a diving knife without scissors function.
  • At least one cutting edge of the knife blade preferably has a corrugated area or a sawtooth structure in order to prevent, for example, fishing lines or fishing nets from sliding out of the scissors when severed.
  • the diving knife can also be used as a saw.
  • the knife blade on the side that interacts with the scissor part as scissors has a recess, which is preferably designed so that it forms an edge perpendicular to the cutting edge of the knife blade or a barb, so that the severing object is reliably prevented from sliding out of the scissors.
  • Both edges of the scissor blade are preferably spaced apart from the two edges of the knife blade in the closed state of the diving knife, so that the knife function is not impaired in comparison with a conventional diving knife.
  • the diving knife preferably has a securing element which prevents the scissor part from opening.
  • the securing element is preferably arranged in the area between the blades and the handles, that is to say where the thumb of the hand holding the diving knife is normally located. This ensures that the diver's knife can be unlocked by simply moving the thumb with one hand and used as scissors.
  • a spring element is preferably used to bias the diving knife into an open state. The second hand is no longer required when operating the diving knife when opening.
  • the diving knife preferably also has a plier function.
  • a pliers function is achieved in that pliers elements, for example pinching surfaces of a pair of pliers or contact surfaces of flat-nose pliers, are formed on the inside of the knife handle and the scissors handle. In order to be able to make good use of the lever law, these surfaces are located near the axis on which the scissor part is articulated to the knife part.
  • the diving knife according to the invention can also be used advantageously in other areas of life, particularly when fishing.
  • Figure 1 is a side view of a first embodiment of the diving knife according to the invention in the closed state
  • Figure 2 is a side view of the first embodiment in the open state
  • Figure 3 is a front view of the first embodiment
  • Figure 4 is a plan view of the first embodiment
  • Figure 5 is a side view of a second embodiment of the diving knife according to the invention, which has a pliers function in addition to the scissors function;
  • FIG. 6 shows a side view of a fourth exemplary embodiment of the diving knife according to the invention, in which the securing element is attached to the end of the handle.
  • the diving knife according to the invention shown in FIG. 1 comprises a knife part 11 with a knife handle 3 and a knife blade 10, which has a first cutting edge 10a and an edge 10b opposite the first cutting edge 10a with a second cutting edge 10c.
  • the second cutting edge 10c of the knife blade 10 is corrugated in this embodiment.
  • the edge of the knife blade 10 opposite the first cutting edge 10a has a cutout 12.
  • the front edge 12a of the recess 12 extends perpendicular to the second cutting edge 10c of the knife blade 10.
  • the diving knife according to the invention comprises a scissor part 8 with a scissor handle 1 and a scissor blade 7 which has a cutting edge 7b and an edge 7a opposite the cutting edge 7b.
  • the scissor part is pivoted on the knife part with a screw 9 about an axis of rotation A.
  • the scissor blade is arranged inside the knife blade.
  • the cutting edge 7b and the edge 7a of the scissor blade opposite it are spaced apart from the cutting edges 10a, 10b of the knife blade in the closed state of the diving knife.
  • the edge 7a of the scissor blade opposite the cutting edge 7b is flattened in such a way that it does not hinder the cutting with the second cutting edge 10b of the knife blade 10 when the diving knife is closed.
  • a securing element 4 which is articulated with a screw 5 on the knife part so as to be rotatable about an axis of rotation B.
  • the securing element 4 has a curved region which, together with the screw 5, forms an opening through which the scissor part 8 extends and can be fixed in the closed position of the diving knife.
  • the curved area can have a gap between which the knife blade and the scissor blade fit so that the diving knife can be opened even further.
  • the scissor part 8 can be fixed in the closed position of the diving knife by the remaining projections of the filter element 4.
  • FIG. 2 the open state of the diving knife of Figure 1 is shown.
  • the same parts have the same reference numerals and are not repeated below.
  • the securing element 4 is rotated in a clockwise direction relative to FIG. 1 by the screw 5 in relation to the drawing.
  • a spring element 2 which is rotatably attached to the knife handle 3 at a point 6, presses the scissor handle 1 no longer secured by the securing element 4 away from the knife handle 3.
  • the spring element 2 is a leaf spring.
  • the recess 12 has a cutting edge 12b which runs essentially parallel to the edge 10b of the knife blade 10 opposite the first cutting edge 10a.
  • the securing element 4 is designed in such a way that it can be operated without problems even with thick gloves.
  • FIG. 3 shows a front view of the diving knife according to the invention from FIG. 1 in the closed state.
  • the securing element 4 encompasses the scissor handle 1.
  • the scissor handle 1 can also be secured only by projections, so that there is a gap between which the knife blade and the scissor blade fit. This enables the diver's knife to be opened even further.
  • the axis of rotation A and the axis of rotation B are shown.
  • the scissor part 8 is rotatably articulated with the screw 9 on the knife part 11.
  • the securing element 4 is rotatably articulated with the screw 5 on the knife part 11.
  • FIG. 4 shows a top view of the diving knife according to the invention from FIG. 1. The parts already mentioned are shown.
  • the screw 9 can be made according to the screw 5 so that the screw 9 does not protrude over the knife blade 10 or the scissor blade 7, but is countersunk. This makes cleaning the diving knife easier.
  • FIG. 5 shows a second exemplary embodiment of the diving knife according to the invention corresponding to FIG. 2.
  • This exemplary embodiment is currently the most preferred exemplary embodiment of the present invention by the inventor.
  • the second exemplary embodiment also has pliers elements 13 and 14 which are each formed on the knife handle and the scissor handle in the region adjacent to the axis of rotation A.
  • These pliers elements are preferably designed like pinching surfaces of a pair of pliers or like the contact surfaces of flat-nose pliers. It is also possible to train both types of pliers in succession in the knife handle 3 and the scissor handle 1 at the same time.
  • the diver can e.g. open the safety lever 4 so that the diver's knife springs open, and open the diver's knife so far that the spring element 2 no longer lies against the scissor handle 1, or arrange the object from the side between the handles.
  • FIG. 6 shows a further exemplary embodiment of the diving knife according to the invention.
  • the same parts are labeled with the same reference numerals and have already been described. Only the differences from the first embodiment are explained here.
