Definitions

• the invention relates to a nutcracker according to the preamble of the claim.
• a nutcracker that is similar in terms of its outer structure but not functionally the same is known from FR 1029351.
• Cracking nuts with a conventional nutcracker consisting of two levers connected at a pivot point generally requires a great deal of force. The sudden breakage of the nutshell caused thereby often means that the pressure exerted on the nut cannot be reduced in time, so that not only the shell but also the nut core is destroyed.
• the invention has for its object to construct a nutcracker that allows the opening of nuts of different sizes in a convenient manner and with little effort while maintaining the classic shape and without any learning requirement.
• the object is achieved according to the invention by the features specified in the characterizing part of the patent claim.
• the distance between the hand levers is constant regardless of the nut size, since the crushing jaw is movable and provided with a toothed ring and can therefore be opened and steplessly applied to the inserted nut regardless of the lever movement. Thanks to the double-lever principle, the pressure on the nut can be cracked effortlessly, despite the minimal effort, compared to a conventional nut cracker and sufficient even very hard nuts such as Brazil nuts. This enables the cracking of nuts even for countless people with weak wrists or wrist diseases. At the same time, the undesirable shattering of the nut core is excluded by the fact that pressure on the hand lever closes the movable crushing jaw by only one tooth pitch and thus only exerts a limited stroke on the nut.
• the pressure on the nut can be increased gradually, i.e. one tooth at a time, until the nutshell has broken open but the core remains undamaged. Since the crushing jaw is continuously applied to the nut, this process is usually completed after two or three lever movements.
• the nutcracker is economical to produce because all parts can be manufactured using the pressure spraying or stamping process.
• Picture 2 shows a nutcracker according to picture 1 as an enlargement without
• the nutcracker shown in Figure 2 consists of two hand levers 2 and 3, lever 2 being firmly connected to an associated crushing jaw, that is to say that the two consist of one piece, while lever 3 is movably fastened on hand lever 2 about axis b .
• the crushing jaw 1 is rotatably attached to the axis a together with the crushing jaw of the hand lever 2 and has a ring gear at its lower end.
• a spring 9, which is attached to the crushing jaw of hand lever 2 presses the crushing jaw 1 in the y direction.
• a feed pawl 5 is movably mounted between Ache b and the ring gear.
• a spring 7 in lever 3 presses the feed pawl 5 into the toothing.
• a cover plate 4 the shape of which is identical to the shape of hand lever 2, covers hand lever 2 and all parts fastened thereon.
• the pawl 6 is moved in the direction z.
• the upward angled pawl end takes the one-tooth feed pawl 5 and releases the sprocket from hand lever 1.
• the crushing jaw 1, which can be pivoted about point a, can now be placed on the nut by hand.
• the ratchet pawl 6 is released, the spring 7 presses the feed pawl 5 into the toothing.
• the feed pawl is movably mounted in the hand lever 3. If the hand lever 3, which rotates about the point b, is pressed against the lever 2 in the direction y, the feed pawl 5 takes the crushing jaw 1 with it and closes the crushing jaws by one tooth pitch.
• a spring 10 opens the lever path and brings the feed pawl 5 into the next tooth.
• the pawl which is rotatably mounted on the hand lever 2 about the point c, holds the tension between the nut and the crushing jaws. It remains in engagement with the ring gear.
• the pressing process can be repeated.
