    The present invention relates to a folding knife with a combination function blade according to the preamble of claim 1.
    Such folding knives find their use preferably in recreational athletes, campers, hikers, craftsmen and / or soldiers, which usually not only carry a simple cutting knife with you, but also want to carry simple tools for a variety of occasions. Such folding knives have a plurality of blade-shaped functional elements, such as. Cutting blades, saws, nail files, scissors, screwdrivers, can openers, corkscrew, bottle opener, etc. and are, for example, in EP-0 619 167 described.
    The folding knife described in EP-0 619 167 has a plurality of functional elements, which are pivotally mounted on pivot pins and are arranged between side by side and at a distance parallel to each other lying boards. In between there are spring pieces, which bear against the functional elements and cause the same in the unfolded working position and in the pivoted-in rest position of a force and / or positive locking of the functional elements. In particular, this jackknife has a can opener and a cap lifter in the form of a blade. These two functional elements abut opposite ends of the same board, i. lie in the same blade level. As a result, the number of functional elements can be increased without simultaneously increasing the thickness of the folding knife. A further increase in the number of functional elements without increasing the thickness of the folding knife, can be achieved by the special design of these functional elements. Thus, in this folding knife, the can opener and the bottle opener have a blade tip which can be used as a screwdriver. Other multifunctional elements, also referred to below as combination function blades, are known, for example, from WO 2012/126 532.
    It is the desire of modern knife manufacturers as slim as possible (small thickness) and narrow (small width) to produce folding knives with as many functional elements. The present invention is therefore based on the object to provide a folding knife with an increased number of functional elements, without having to increase the thickness and / or the width of the folding knife.
    It is a particular object of the present invention to provide a combination function blade, with which different functional blades can be replaced such that in the same blade level, an additional functional blade can be used.
    This object is achieved according to the invention by a folding knife with the features of claim 1 and in particular by a folding knife with a trained as a can opener functional element, hereinafter also called only can opener, and designed as a capsule lifter functional element, hereinafter also referred to only capsule lifter, wherein the can opener has a first functional side with a claw, an inner edge, a piercing tip and a cutting surface and the cap lifter has a second functional side with a hook, an inner edge and a rolling edge. According to the invention, the can opener and the bottle opener are integrated (integrally) in a combination function blade pivotably mounted about an axis of rotation in such a way that the first and second functional sides are located away from one another (i.e., back to back). In this case, the point of the claw furthest away from the axis of rotation defines a first blade radius about the axis of rotation and defines the secondmost blade radius about the pivot axis furthest from the axis of rotation, the first blade radius and the second blade radius being of different sizes ,
    In an advantageous embodiment of the present invention, the ratio of the larger to the smaller blade radius is greater than or equal to three to two, for example, R1 / R2≥3 / 2, and preferably greater than or equal to four to two, for example, R1 / R2 ≥ 4/2.
    In particular, the combination function blade is designed angled so that it comes to rest in the rest position substantially completely between the handles. The respective inner edges of the functional elements are preferably parallel to each other and are inclined to their axis of action. This angle of inclination is preferably about 40 °, but may also have a different inclination.
    In a particular embodiment, the combination function blade is designed such that a the rotary axis side end opposite blade end of the combination function blade is in working position on a fixed axis defined by the two outermost axes of rotation. This design allows any forces acting on the blade torsional forces, especially when the blade end is designed as a screwdriver, symmetrically catch.
    In a particular embodiment, the folding knife has a continuous, preferably slot-shaped or cruciform opening. This opening is also in the case of folded-in blades, i. with the blades at rest, open and allowed as a slot, for example, the holding of fishing supplies or tool aids with folded blades.
    Here is to be understood by a combined function blade with integrated functional elements, a one-piece combination function blade.
    In the following, the invention will be explained in more detail with reference to embodiments and with the aid of the figures. Showing:<Tb> FIG. 1: <SEP> an exploded view of a folding knife known type;<Tb> FIG. 2a-c: <SEP> a schematic representation of a first embodiment of a folding knife according to the invention with integrated functional elements;<Tb> FIG. 3a-c: show a schematic representation of a preferred embodiment of a folding knife according to the invention with integrated functional elements;<Tb> FIG. 4: <SEP> a schematic representation of the design principle of a multifunction blade according to the invention;<Tb> FIG. 5a, b: <SEP> is a schematic representation of the functioning of a folding knife according to the invention;
    The exploded view shown in Fig. 1 makes the structure of known folding knife clearly. These have on the outside each a handle shell 2, 2, between which two outer 3, 3 and a central board 4 is arranged. Between these boards 3, 3, 4 are various functional elements 5, 6, 7, 8, 9, provided, here a cap lifter 5, a can opener 6, a Stechahle 7, a cutting blade 8 and a screwdriver 9. These boards and functional elements attached to pivot pins 11, 11, which define axes of rotation 12, 12 for the respective functional elements.
    The schematic representation in Fig. 2a shows a first embodiment of an inventive combination function blade 13 in the unfolded position, respectively. Working position 14 and the same combination function blade in the folded position, i. Rest position 14. This combination function blade 13 combines two functional elements of known type, namely a cap lifter 5 and a can opener 6 such that their function sides facing away from each other (ie back to back) are arranged, the functional side of the cap lifter 5, as shown in FIG. 2b and hereinafter also called first functional side, a hook 15, a first inner edge 20 and a rolling edge 16, while the functional side of the can opener 6, as shown in Fig. 2c and hereinafter also referred to as the second functional side, a claw 17, a second inner edge 22, a piercing tip 18 and a cutting edge 19 has. The one-piece design of these two functional elements 5, 6 requires only a common pivot 11 and creates space for another functional element, eg. A corkscrew.
    A preferred embodiment of the inventive combination function blade 13 in the unfolded position, respectively. Working position 14 and in the folded position, i. Resting position 14 is shown schematically in Fig. 3a. This combination function blade 13 combines in an analogous manner two functional elements, as shown in Fig. 3b and 3c. In particular, Fig. 3b shows a cap lifter 5 of known type, which has on its functional side a hook 15, a first inner edge 20 and a rolling edge 16. The can opener 6 shown in Fig. 3c in turn has a claw 17, a second inner edge 22, a piercing tip 18 and a cutting edge 19, but shown in a different embodiment than in Fig. 2c. The inventive integration of the two functional elements and in the embodiment shown here with an angular displacement of the two functional elements, the width of the combination function blade 13 can be significantly reduced, here to 83% compared to the embodiment of FIG. 2a. It is understood that in this embodiment, a peripheral part of the combi function blade 13 is angled such that preferably trained as a screwdriver blade end 21 of the combi function blade 13 in working position 14 any torsional forces symmetrically on the two outer trunnions 11, 11 transmits, i. on the central axis 10 defined by the two pivot axes 12, 12 and in the folded-in state (rest position 14) lies substantially within the grip shells 2, 2, as can be seen from FIGS. 5a, 5b.
    Fig. 4 illustrates the design principle of a preferred embodiment of the inventive combination function blade 13 in detail. In this case, the first and second inner edges 20, 22 of the respective functional sides are parallel to one another and define a central axis 23. This central axis 23 is determining the shape and function. In particular, the angle of inclination α to the action axis 25 of the combination function blade 13 proves to be decisive for the radii R1 and R2. The design principle of the preferred embodiment of the combination function blade according to the invention shown here is based on an angular displacement in which, on the one hand, the center axis 23 formed by the opposing functional elements is inclined by an inclination angle α against the action axis 25 and, on the other hand, the two functional elements are parallel to the common center axis 23 and be moved parallel to each other. The optimum inclination angle α results from the positions lying on the outermost periphery and the action axis closest positions Q1, Q2 of the combi function blade 13 in the rest position, i. folded state. It is understood that the common blade end 21 is angled so that the entire combi function blade 13 is at rest within the grips 2, 2. The principle used for this purpose (rotation and translation of the central axis) makes it possible to substantially reduce the required width of the multifunction blade, for example to 83% with respect to the width of a multifunctional blade, as shown in Fig. 2a, i. without such a design.
    5a, b illustrate the design of a multifunctional blade 13 according to the invention. FIG. 5a shows the folding knife 1 according to the invention in its folded position, here also rest position 14, while FIG. 5b shows the folding knife 1 according to the invention in its unfolded position, FIG. also called working position 14, shows.
    In particular, Figure 5b illustrates how the point P1 of a first functional element (here a claw 17) spaced farthest from the trunnion axis 12 defines a first blade radius R1 about the trunnion axis 12 and like the farthest point P2 of a second Functional element (here a hook 15) defines a second blade radius R2um the axis of rotation 12, wherein the first blade radius R1 and the second blade radius R2 are different in size. In this illustration, the ratio of the larger R1 to the smaller blade radius R2 is greater than or equal to four to two, i. R1 / R2≥ 4/2. In particular, the combination function blade 13 is designed angled such that a the rotary axis side end opposite blade end 21 in the unfolded end position (working position 14) on a defined by the outer pivot axes 12, 12 central axis 10. This is of particular importance when the blade end 21 is designed as a screwdriver. In addition, the angled design of the combination function blade 13 also means that it comes to lie substantially completely in the rest position 14 between the handles 2, 2.
    Fig. 5a makes it clear that this preferred embodiment of the inventive combination function blade 13 is designed such that the width of the folding knife 1 is substantially reduced. In particular, as compared with the embodiment of Fig. 2a, the distances of the outermost ones, i.e., the outermost ones, are. the positions farthest from the action axis 25, Q1, Q2, of the combi function blade 13 at rest, i. when folded, reduced by at least 5%
    In a particular embodiment, the inventive folding knife 1 has a through opening 26. This opening 26 is preferably slot-shaped or cross-shaped and also with folded blades, i. with the blades at rest, open. This through opening 26 allows their use as a slot, for example. The holding of fishing accessories or tools with folded blades.
    The advantages of the present invention will be readily apparent to those skilled in the art and, in particular, be seen in the ability to populate a folder with additional functional elements without increasing the thickness and / or width thereof.
    It is understood that here, for example, shown design principle, namely different functional elements back to back in a single combi function blade angularly shifted to integrate with differently shaped and / or different kind of functional elements, eg. Wire bender, bit wrench with bit holder, small scissors , Loupes, hook blades, small spirit levels, lighting elements, etc. are possible. The gained blade space can be used for additional functional elements.
