Definitions

  • the present invention relates to a folding knife with a base on which a blade is pivotally mounted so that the blade can be moved from a non-use position to a use position in which the blade protrudes from the base, and with a first lever arm, which has a first Joint is pivotally connected to the blade and pivotally connected via a second joint to a second lever arm, which is coupled via a third joint pivotally connected to the base.
  • Such a folding knife is from the US 7,905,022 B2 known.
  • the lever mechanism with the first and the second lever arm allows a locking of the blade with a hand embracing the knife.
  • the base and the first and the second lever arm form the handle of the knife.
  • the hand is both on the outside of the first lever arm and on the second lever arm.
  • the first lever arm has an end piece protruding beyond the second joint and resting against the base in the position of use.
  • the three hinge points lie on a common line, so that a locking of the blade over the stiffened in such a way two lever arms is effected.
  • the second lever arm has an actuating cam projecting the third joint.
  • the knife is or is locked in the 80 ° position (or more). If the user's hand is placed on the actuating cam, pivoting of the two lever arms takes place against each other. The two pivot arms thus shorten the distance between the third and the first joint, whereby the blade is pivoted in the direction of the non-use position.
  • the previously known folding knife has several disadvantages.
  • the folding knife can not be adjusted from the non-use position to the use position with one hand.
  • Such a one-handed handling with a single hand holding the folding knife can be desired with below.
  • More problematic, however, is the operation of the second lever arm to pivot the blade from the use position to the non-use position. Because the user's hand is placed here on a portion of the second lever arm, which is close to the pivoting range of the tip of the blade, so that an injury is to be feared.
  • Incidentally proves also the locking of the use position solely by the orientation of the two lever arms relative to each other as unreliable.
  • the present invention is based on the problem of specifying a folding knife of the type mentioned with improved usability.
  • a folding knife of the aforementioned type in which in the use position, a first hinge connection line with a second hinge connection line an angle of between 178 ° and 95 °, preferably between 175 ° and 150 ° includes.
  • This angle is provided between the two hinge connection lines and on the base side facing the two lever arms in the position of use.
  • the first joint connecting line is formed by a line connecting the pivot axes of the first and the second joint.
  • the second linkage connects the pivot axes of the second and third links.
  • the folding knife is preferably designed so that the angle can not be set greater than the maximum value specified above, even if the user's hand engages around the handle formed by the base and the two levers, d. H. push the two levers towards the base.
  • angularly aligned lever arms does not result in complete locking alone by the rectilinear alignment of the lever arms relative to each other such that all joints are with their pivot axes on a line, d. H. the lever arms enclose between them an angle of 180 °. Rather, the inventive alignment of the lever arms allows pivoting of the blade from the use position to the non-use position solely by appropriate pressure on the free end of the blade for pivoting about a hinge point of the blade.
  • the folding knife is usually formed so that the cutting edge of the blade is pivoted towards the base during pivoting into the non-use position and accordingly rests in the use position inside in a knife handle, for example, the first lever arm and the Base includes.
  • the first and also the second lever arm within the knife handle possibly within one or more handles, which is / are usually mounted on the base, are movably mounted.
  • such handles or handle covers usually leave a part of at least the first lever arm free, so that by gripping the base and the first lever arm locking can be achieved. The pressure against the first lever arm prevents that the distance between the first and the third joint is reduced and thus the blade is pivoted in the direction of the non-use position.
  • the second lever arm is within a knife handle having the first lever arm and the base.
  • the envelope surrounding the base and the first lever arm accordingly envelops the second lever arm.
  • the second lever arm is not reached by the user in the usual handling of the knife. Rather, the second lever arm is inside the knife handle. Only the first lever arm is exposed on the opposite side of the base and is touched by the hand enclosing the knife handle. The second lever arm is not touched by this hand and is not touchable by this hand.
  • the orientation of the blade relative to the base in the Operating position causes and which includes a blade-side stop surface and a base-side stop surface. These two stop surfaces are in the use position to each other.
  • the stop according to this development preferably causes a direct abutment of blade and base. The two parts are accordingly securely fixed against each other, on the one hand by the stop and on the other by that between the base and the blade provided blade joint. The determination of the blade relative to the base is therefore not - as in the prior art - on the various levers that bring each game and thus no precise definition of the blade in the position of use with it.
  • a stop pin is preferably provided integrally with a blade body forming the blade.
  • This stop pin usually towers on both sides of the blade and is accordingly on both sides of the base.
  • the base usually has for this purpose adapted to the contour of the stop pin cocoon stop recess, so that the blade is securely fixed relative to the base.
  • a third hinge connection line connecting the pivot axis of the blade and the first hinge with the first hinge connection line forms an angle of between 70 ° and 88 °, preferably between 75 ° and 85 °.
  • the aspect ratio of the first hinge connection line to the third hinge connection line should be between 14 and 9.
  • this aspect ratio is set to a value between 11 and 12.
  • the aspect ratio of the first hinge connection line to the second hinge connection line should be between 7 and 5.
  • this aspect ratio is set to a value between 5.8 and 6.4.
  • the corresponding articulation connection lines each extend exactly from the pivot axis of the respective articulation to the pivot axis of the other articulation for this dimensioning, ie. H. for example, for the first articulation link between the pivot axis of the first articulation and the pivot axis of the second articulation.
  • the blade is formed by a blade body having an actuating leg opposite the blade with respect to the pivot axis of the blade, which in the non-use position projects beyond the base.
  • the actuating leg preferably forms an actuating head, which is rounded.
  • the blade body is usually made of a piece of sheet metal, on which the cutting edge through Grinds tapered and sharply shaped.
  • the actuating head is usually formed by working out of the metal sheet.
  • the actuating head preferably has a knurled surface.
  • the actuating head In the non-use position, the actuating head is usually upstream of the free end of the base, more preferably approximately in the region of the stop of the blade in the position of use or the stop recess for receiving the stop. Accordingly, a hand holding the jackknife on the handle can easily reach the operating head with its index finger to pivot the blade from the non-use position to the use position.
  • the handle of the knife usually lies between the provided on one side of the thumb and the finger provided on the other side, the index finger with his fingertip is approximately at the level of the blade, ie between the contact surfaces of the thumb and the other finger of the blade handle.
  • the knife After swinging the blade in the position of use, the knife can be pivoted by about 90 ° in the palm, so that the four fingers rest against the blade body, but at least on the outside of the first lever arm and thus set the blade in the position of use and the thumb either outside at the transition between the base and the blade body rests against at least one of the two or laterally engages around the blade handle or engages around the grip of the knife handle by concerns on the index finger.
  • the knife can be opened with one hand and be transferred into a handle safely holding the knife in the position of use by the pressed in the direction of the base first lever arms at an angle ⁇ of 178 ° or less is locked.
  • a concave trough which is formed by an edge surface of the blade body and merges in the use position by a molded by the first lever arm trough portion.
  • the concave recess and the trough portion formed by the concave recess is usually the index finger of the knife handle embracing hand. The concave recess improves the secure holding of the knife.
  • a locking device is provided, through which the blade in the position of use is determinable.
  • This locking device is usually a hand-operated locking device. It is usually designed so that it can not be accidentally operated to set the blade in the position of use. For this purpose, the locking device opposes an unwanted actuation by appropriate measures a certain resistance.
  • the locking device is usually also formed so that it can not be operated with the hand holding the knife. In particular, it can not be operated with the hand that encompasses the knife handle, ie base and first lever arm.
  • the locking device preferably has a pivotable detent pawl, which cooperates in a locking position with a latching projection which is formed on the second lever arm.
  • the latch is usually spring-biased, which not only favors a predetermined orientation of the latch usually in the non-locking position, but also leads to a certain pressure against an actuating element to the latch, which rests against it, and thus this actuator secures against accidental actuation.
  • a locking actuating element acting on the detent pawl the actuating surfaces of which are arranged on the base so that the locking actuating element is not to be operated with a hand engaging the folding knife.
  • the locking actuating element may be formed for example by a locking wheel, which is pivotally mounted on the base.

  • the locking wheel has a substantially flat and non-locking surface abutting the latch in a non-latching position and a locking surface extending substantially transversely thereto.
  • This locking surface is rather linear or punctiform in the locking position on the latch.
  • the flat contact between the locking wheel and the latch in the non-locking position further promotes the unwanted adjustment of the locking wheel in the locked position.
  • between the locking surface and the non-locking surface provided a cam, which opposes the unwanted pivoting of the locking wheel between the two positions of use further resistance.
  • the cam preferably has a greater radial distance from a Verriegelungsradschwenkachse than the non-locking surface and / or the locking surface.
  • the first lever arm is provided with an end region projecting beyond the second joint, which, at least in the position of use, is provided directly to a rear end region of the base.
  • This provided on the first lever arm end usually covers the third joint and thus usually completely the second lever arm.
  • At least one usually directly in operative connection with the base and the first lever arm stationary spring element is provided, which urges the blade of an intermediate position between the use position and the non-use position in the use position or in non-use position.
  • the spring accordingly promotes a defined support of the blade relative to the base.
  • the blade is held biased by the spring either in the non-use position or in the position of use. Accordingly, the spring facilitates, at least after exceeding a dead center of the pivoting movement, the movement of the blade into the respective other position.
  • the spring is designed as a helical tension spring whose free ends are connected to identically formed fastening eyes. These attachment eyes are each pivotally secured to the first lever arm or the base.
  • the force action lines of this helical tension spring makes an acute angle with the first articulation connection line, this applies both to the position of use and to the position of non-use. In the position of use, the acute angle ⁇ is, for example, between 15 and 20 °.
  • the spring in the position of use exerts a lower spring force than in the non-use position.
  • more work must be done on the spring to pivot the blade from the position of use to the intermediate position as when pivoting the blade from the non-use position to the intermediate position.
  • the tension energy of the spring in the non-use position is thus greater than the tension energy of the spring in the position of use.
