Definitions
- the invention relates to a tool for opening nuts, in particular for cracking nutshells according to the preamble of claim 1.
- nutcracker Tools of the type mentioned for opening nuts or cracking nutshells are known as so-called nutcracker.
- Such nutcrackers come in different forms and variants.
- nutcrackers of conventional design consist of at least two
- Breaking levers which are rotatably connected at the top by means of a joint.
- the nut is inserted between the breaker levers and broken by squeezing the levers.
- the nuts are clasped by two concave jaws and crushed under a great deal of effort, the user can barely control the tool especially in the crucial phase of nut breaking, whereby the risk exists that in addition to the nutshell and the nut kernel gets destroyed.
- the jaw parts are opened for inserting nuts. It is disadvantageous that the nuts can be inserted only from the side between the jaw parts, which inevitably complicates the handling. Inserting a nut from above with a nutcracker that is roughly horizontal has the disadvantage that the nut drops slightly downwards. But also the variant of the introduction of the nut from below is not satisfactory, because the user of the tool is forced to loosen the thumb from the nut, then to put it over the handle part.
- the object of the present invention is to design a tool of the aforementioned type such that the opening of nuts or the cracking of nutshells is optimized.
- the tool according to the invention differs from the tool according to the US 4425407 essentially in that the
- Breaking lever of the tool are two-sided lever, which are connected to each other by a hinge, which is arranged differently than in the known tool at the transition from the handle parts to the jaw parts.
- the rotatably connected jaws are able to form a kind of "mouth" in their spread position
- Internal cheek surfaces are provided with teeth, wherein the inner side of the cheek of a jaw, for example, the lower jaw, concave and the inner cheek of the other cheek, for example, the upper jaw, are convex.
- the jaw having the concave inner side is larger than the jaw having the convex inner side, the concave inner side having more teeth than the convex inner side.
- This design has the advantage that nuts of various types, shapes and sizes can be picked up by the nutcracker's "mouth” since the jaws can be spread in a suitable manner according to the larger shape of the nuts This results in the further advantage that when pressing the tool, the shell is indeed cracked, but the nut core itself is not damaged.
- the tool according to the invention can be easily held so that the jaw or the jaw lever arm is held with the concave inner surface below the other jaw or the other jaw lever arm with the convex inner surface, so that the nut laterally into the mouth the between the jaws on the concave - A -
- Inner surface of the jaw is laid and can be cracked effortlessly and controlled by the teeth of the convex-shaped jaw.
- the tool head with the two jaw lever arms is angled sideways, so that even with upright support of the tool, the jaw or the jaw lever arm is arranged with the concave toothed inner surface below the jaw or the jaw lever arm with the convex inner surface.
- Fig. 2 shows a second embodiment of the invention
- Fig. 3 shows a third embodiment of the invention
- FIG. 4 shows a fourth embodiment of the tool according to the invention.
- Fig. 6 shows a sixth embodiment of the invention
- the drawing shows in Fig. 1, a tool 2 two, which is advantageously used especially as a nutcracker.
- the tool 2 consists of two two-sided levers 4, 6, each with a first lever arm 12, 14 and a second lever arm 8, 10, wherein the first lever arms 12, 14 a jaws 12.1, 14.1 having tool head 15 and the second lever arms 8, 10 handles 11, 13 form.
- the two levers 4, 6 are at the transition from the handles 8, 10 to the
- the tool head 15 with the two jaws 12 ', 14' is such angled laterally that seen in the handle plane at about upright held tool a lower with concave or convex, teeth 18 exhibiting inner surface 17 provided jaw lever arm 12 and an upper with convex or concave, teeth 20 having the inner surface 19 provided jaw lever arm 14 are formed.
- the lower jaw lever arm 12 with the concave inner surface 17 is formed in the embodiments of FIGS. 1-5 longer than the upper jaw lever arm 14th
- the two jaw lever arms 12, 14 of the tool diverge arcuately starting from the hinge point 16, so that the two jaw lever arms 12, 14 form a mouth 22 into which a nut to be cracked can be inserted laterally easily and comfortably.
- Reference numeral 26 denotes a handling facilitating projection.
- the two levers 4, 6 are biased in the opening direction of the two jaw lever arms 12, 14.
- the bias is generated by a spring 28 which is supported on the one hand on a jaw lever arm 14 or its associated handle lever arm 8 and on the other hand on the other jaw lever arm 12 or its associated handle lever arm 10.
- the spring 28 is disposed near the hinge 16 and may be formed by a coil spring as shown in FIG.
- the spring is a torsion spring in the form of a wire-shaped spring 29, cf. Fig. 5a and Fig. 5b, which is arranged around the rotation axis 16 around in one of the lever arms 8,10 and whose ends 31, 33 are angled axially in opposite directions and inserted into associated holes 35, 37 in the open position of the two lever arms, and pretension the lever arms against each other, cf. Fig. 5b and 5c.
- the handling of the tool according to the invention or the nutcracker according to the invention is as follows: A nut to be cracked N is inserted laterally into the mouth 22 between the two jaw lever arms 12, 14 as far as the stop and on the positioned lower jaw lever arm 12, see. 4 and 6.
- the two handles 11, 13 are compressed, at the same time the two jaw lever arms 12, 14 are moved towards each other, in particular the upper jaw Hebelarmteil 14 with the convex inner surface against the lower jaw Lever arm 12 is pivoted with the concave inner surface and the loaded nut N is applied.
- the hand force then exerts the nutshell of the inserted nut through one of the teeth of the convex jaws, without damaging the nut kernel.
- a further development of the invention provides for forming the joint 16 of the tool or nutcracker 15 as a work-facilitating ratchet or ratchet by means of which the hand force exerted for nutcracking can be transmitted to the nut by stepwise pivotal movement of at least one lever arm, in particular the lever arm with the convex jaw.
- a nutcracker can also be used successfully by people with low hand strength.
- FIG. 2 shows the nutcracker according to the invention with an integrated power amplification mechanism.
- the two jaw lever arms 12, 14 are in operative connection with one another via a transmission 115 that transmits a force.
- the tool according to the invention or the nutcracker invention shown in FIG. 2 consists of three mutually movably connected elements.
- the lower, the concave inner surface 17 having jaw lever arm 12 is integrally formed with the front handle 11.
- the upper jaw lever arm 14 is rotatably mounted about an axis of rotation 116 in a handle 11 facing away beyond the lower jaw lever arm 12 extended extension 117 and has at a free end 120 of the jaw lever arm 14 opposite end 122 a circular arc toothed segment 124 on.
- This arcuate tooth segment 124 forms the axis of rotation 116.
- the circular arc Tooth segment 124 is engaged with a toothed segment 126 which is formed in a circular arc around a rotation axis 128 as a center, which is arranged in the extension 117 of the front handle 11 and about which the rear handle 13 is rotatably mounted. It is here ( Figure 2) a construction with two axes 116, 128th
- the toothed segments 124 and 126 have different radii, wherein the radius of the toothed segment 126 of the rear handle 13 is selected to be smaller than the radius of the toothed segment 124 of the front handle 11.
- leg spring 132 surrounding leg spring 132 is provided, which is supported with one leg 134 on the rear handle 13 and the other leg 136 on the front handle 11, which biases the two jaw lever arms 12, 14 in the open position.
- the spring is also a torsion spring in the form of a wire-shaped spring 29, as in the embodiment of Fig. 5a and Fig.5b, which is arranged around the rotation axis 116 in one of the lever arms 8,10 and the ends 31, 33 axially are angled in opposite directions and in associated holes (not shown) of the two lever arms are introduced and bias the lever arms against each other in an open position of the mouth 22.
- a modification of the formation of the teeth 18, 20 is shown.
- the teeth are different than usual slightly obliquely inwardly directed, ie, that at least the teeth 18 of the concave inner surface 17 of the lower jaw 12 are formed obliquely inwardly in the direction of the hinge 16, 128 facing. This design achieves a better and more secure hold of a nut inserted between the jaws, since the nut is pressed inwardly into the mouth 22 when the handles 4, 6 are pulled together. A twisting and slipping of the nut is certainly avoided.
- Fig. 4 of the drawing shows a further embodiment of the tool according to the invention, in which in the lower concave, toothed inner surface 17 of the lower jaw 12, a groove-like depression 150 is incorporated.
- This recess is preferably formed centrally along the entire inner surface. This ensures that the nut resting on the lower jaw N does not touch the toothing 18 of the lower jaw 12, as hitherto only at one point but at two points P 1 and P 2, so that the nut N between the two jaws 12, 14 touches a total of three Points, namely the points P1 and P2 of the lower toothing 18 and the point 3 of the upper toothing 20, whereby a much better grip is achieved. At the same time, the cracking effect is significantly increased.
- a further embodiment of the tool according to the invention is shown in the trough-like depression 150, see. Fig. 4, a replaceable insert 152 inserted from an elastic, non-slip and abrasion resistant material.
- the insert 152 projects slightly beyond the tips of the teeth 18.
- the insert is made of silicone.
- the silicone insert significantly improves the grip of the nut shell in the groove-like depression.
- the elastic silicone material is forced through the nut into the groove-like depression, at the same time the nut is acted upon by the teeth of the lower jaw. Slippage or twisting of the nut in the tool is effectively prevented.
- the grip of the two jaws of the tool or nutcracker can be further increased by the fact that the silicone insert is provided with transverse grooves 160.
- a biasing spring is - preferably in the embodiments of FIGS. 1 - 4 - used a torsion spring in the form of a wire spring 29 which is arranged around the rotation axis 116 in one of the lever arms 8, 10 and the ends 31, 33 axially in opposite directions Directions are towards each other or away from each other and are inserted into associated holes 35, 37 of the two lever arms 8, 10 and bias the lever arms 8, 10 against each other in mouth opening position.
- FIG. 6 shows a further embodiment of the tool or nutcracker 15 according to the invention, which differs substantially from the embodiments described above in that the lower jaw lever arm 12 has a convex, toothed inner surface 17 and the upper jaw lever arm 14 has a concave, toothed inner surface 19 having.
- the handles 11, 13 are approximately at right angles during normal, natural holding of the nutcracker to the user's body, and the jaw 22, which is wide open by the prestressed spring 29 and the spread handles 11, 13, is laterally positioned approximately at right angles to the handles.
- the conically spread mouth 22 receives nuts of various sizes. The nuts are set in the mouth until they pass into contact with the teeth 18, 20 and / or the silicone insert 152 of the jaw lever arms 12, 14. Then, the handles 11, 13 are compressed to crack the nutshells. Since the nutcracker is always fully open in the starting or basic position for cracking, a relatively small movement, ie a small distance of a few millimeters, is sufficient to crack a nutshell.
- the inner surface 19 of the upper jaw lever arm 14 is concave and the inner surface 17 of the lower jaw lever arm 12 is convex.
- the open mouth 22 is preferably positioned at an angle ⁇ of about 70 ° to the open handles 4, 6, so that the nuts are inserted laterally and slightly obliquely from below into the mouth in the usual, natural attitude of the nutcracker.
- the handling of the nutcracker and the effectiveness of the cracking process are in the two embodiments with respect.
- the position of the concave and convex inner surface 17, 19 in the embodiments of FIGS. 1-5 on the one hand and Fig. 6 on the other hand the same.
