Definitions

  • the invention relates to a folding knife according to the preamble of claim 1.
  • the stop on the cantilever is generally formed on a hook part extending towards the blade part, which extends under spring force in the region of the transverse axis into a complementary groove of the blade part, so that the blade part in the position shown, where it is axial is essentially aligned with the handle part, is fixed in both pivot directions.
  • the hook part is then lifted out of the groove, whereupon the blade part can then be pivoted back onto the grip part, where in particular the cutting edge is sunk in a slot-like accommodation space.
  • either the cantilever is arranged on the handle part so as to be pivotable about a transverse axis and is biased into the engagement position by a special spring.
  • the cantilever can also be positively connected to the handle part at the end area facing away from the stop end and by a special lever with resilient bending be pivoted so that the hook part is lifted out of the groove of the blade part.
  • the cantilever itself must have appropriate elastic properties.
  • the cantilever is sunk in a longitudinal slot-like recess of the handle part, which lies directly above the slot-like accommodation space for the blade part.
  • the accommodation of the cantilever in the longitudinal slot-like recess is in any case such that the cantilever can carry out the required pivoting movements when it is acted upon by hand, that is to say is mounted in a correspondingly movable manner.
  • a folding knife is already known, in which a fork member is axially displaceably arranged on the handle part in order to either release the blade part pivotally attached to the handle part for pivoting relative to the handle part or to fix it in the pivoted-out position.
  • mutually cooperating levers are provided on the handle part, each pivotable about its own axis, in order to be able to fix the blade part either in the unfolded position or to fold it back into the handle part.
  • the aim of the invention is to provide a further folding knife of the type mentioned at the beginning.
  • the need for special spring elements or special and articulated actuating levers is to be avoided by the folding knife according to the invention.
  • the spring beam according to claim 2 is also particularly advantageous axially, i.e. set in its longitudinal direction.
  • rotary guide for the cantilever on the handle part serves a simple manufacture, because after installing the rotary guide pin on the handle part with the blade part exposed and engaging in the groove hook part of the cantilever, which is not preloaded, the blade can be removed and before mounting the stop pins the cantilever is pivoted by a small amount of angle so that the required resilient bias is present when the blade part is subsequently inserted.
  • stop surfaces according to the invention are formed on stop elements which also ensure an axial fixation of the cantilever in all pivot positions.
  • the folding knife according to the invention has a handle part 11 and a blade part 12 arranged thereon about a transverse axis 13.
  • the cutting edge 37 is provided on the blade part.
  • a longitudinal slot-like recess 34 is provided, in which an elongated spring bar 14 with a rectangular cross section is guided laterally, but is displaceably accommodated in the direction of the pivoting movement of the blade part 12.
  • the cantilever has a longitudinal slot 18 which passes completely through it in the direction of the transverse axis 13.
  • the longitudinal slot 18 only has to extend essentially in the longitudinal direction of the handle part 11 or the spring bar 14 and can also deviate somewhat or in whole or in part from this longitudinal direction, as can be seen from FIGS. 1, 4 and 5.
  • the longitudinal slot 18 is preferably located in the half of the spring bar 14 facing the front hook part 31.
  • the hook part 31 engages in a groove 32 of the blade part according to FIG. 1, essentially over the transverse axis 13, so that the hook member 31 performs a movement substantially away from the transverse axis 13 when disengaged from the groove 32.
  • the hook part 31 has a front stop 16 and a rear stop 38 which cooperate with counter stops 17 and 39 of the blade part 12 formed by the flanks of the groove 32.
  • the blade part becomes by the engagement of the hook part 31 in the groove 32 12 in the shown position shown in FIGS. 1 to 3 rotatably fixed to the handle part 11.
  • the spring bar 14 must be sufficiently axially fixed within the handle part 11 in the manner described in detail below.
  • the longitudinal slot 18 has three substantially circular extensions 27, 28, 30 at axial distance, which extend parallel to the transverse axis 13 and are penetrated by complementary stop pins 25, 26 and a rotary guide pin 29, respectively Both ends are fixed on the handle part 11.
  • the longitudinal slot 18 is divided into four sections 18a, 18b, 18c, 18d, which in the manner shown in FIGS. 4 and 4a open at least substantially tangentially in the extensions 27, 28, 30, such that the cantilever 14 in the two axial directions 40 by the axial stop surfaces 47, 48 thus formed on the spring beam 14 and the counter-stop surfaces 49, 50 on the pins 25, 26, 29, even in the spread state of the longitudinal slot 18, is so securely fixed that a perfect and safe Fixation of the blade part 12 in the position shown in FIG. 1 is guaranteed.
  • actuating lever arm 35 is available on the side of the spring bar 14 facing away from the hook part 31, to which an actuating part 36 adapted for example to the finger shape can also be connected, which protrudes outward from the grip part 11.
  • the folding knife according to the invention is assembled as follows:
  • the blade part 12 with the spring bar 14 is attached by attaching a pin 41 in the region of the axis of rotation 13 and only the rotary guide pin 29 in the extension 30 on the handle part 11, specifically in the engagement position of the hook part 31 and the groove 32.
  • the spring bar 14 is not yet resiliently clamped.
  • the blade part 12 is then dismantled by removing the pin 41 and the spring bar 14 is then pivoted somewhat counterclockwise in the views of FIGS. 1 and 4 about the pivot axis 15, which coincides with the axis of the rotary guide pin 29. Then the holes for the stop pins 25, 26 are drilled and the stop pins 25, 26 inserted into the extensions 27, 28 and fixed on the handle part 11.
  • the spring bar 14 is now pivoted clockwise by exerting pressure on the actuating part 36 in the direction of the arrow F in FIG. 1, the edges 21, 22 of the longitudinal slot 18 against the corresponding stop surfaces 19, 20 according to FIGS. 1, 4 and 4a the stop pins 25, 26 create, whereupon the longitudinal slot 18 in the direction of arrows 42, 43 in Fig. 4a is sprung open. Due to the shell-like design of the axial stop surfaces 47, 48, the axially positive mounting of the spring bar 14 on the handle part 11 is maintained.
  • the blade part 12 can now be mounted on the handle part 11 by means of the pin 41. If the spring bar 14 is then released, the longitudinal slot 18 contracts again due to the resilient restoring forces, so that the hook part 32 either in 1 extends into the groove 32 or is resiliently supported on a cam track 44 provided at the end of the blade part 12, which ends at the groove 32. Due to the assembly according to the invention, however, the longitudinal slot 18 can no longer contract completely in the engaged position of the hook part 31 in the groove 32 according to FIG. 1, so that a certain resilient latching force also remains in the extended state of the blade part 12.
  • the folding knife is now ready to use.
  • a stop web 23 which is fixed to the handle part and has an elongated cross section extending in the longitudinal direction of the spring bar 14 is provided, which is accommodated in a complementary extension 24 of the longitudinal slot 18.
  • the longitudinal slot 18 is divided into two sections 18a, 18b, which in turn at the top or lower end of the extension 24 open in such a way that, even when the longitudinal slot 18 is expanded, the stop bar 28 remains positively connected to the spring bar 14 in the axial direction, for this purpose by means of axial stop faces 47, 48 on the spring bar 14 and counter-stop faces 49, 50 on the stop bar 23 be available.
  • the stop faces 19, 20 in FIGS. 5, 5a are provided on the lower surface of the stop web 23 on the far left or on its upper surface on the far right. They work there when the spring bar 14 is pivoted clockwise about the centrally provided pivot axis 15 with the opposite edges 21, 22 of the extension 24 of the longitudinal slot 18.
  • the axial distance between the stop faces 19, 20 is preferably about 10 to 30, in particular about 20% of the total length of the longitudinal slot 18. In absolute terms, the axial distance between the stop faces 19, 20 is 1 cm, while the total length of the longitudinal slot 18 is 4 to 6 and in particular is about 5 cm.
  • the thickness of the spring bar 14 corresponds to that of the spring bar of conventional folding knives and is approximately 2 to 3 mm.
  • the handle part 11 consists essentially of metal, but inserts 45 (FIGS. 2, 3) made of plastic or wood can be provided, which are fastened to the handle part 11 by means of screws 46.
