Abstract

The shears have handles (6,13) and arms (3,4) operating about a pivot (2). The arms are cranked and the pivot point is in the upper region of the two arm cranks, above the cutting edges (10,17). The inner part of the cutting edges (18,19), are curved to form an approximate right angle. Preferably, each arm has a cutting section (8,16) and a middle section (7,14) which is bent upwards, the pivot point being in the latter section, above the cutting edges. The handle ends (5,12) are preferably bent back in the direction of the cutting plane.

Description

The invention relates to a cutlery for baking and the same as pizza, as known from DE 93 02 566 U1.

When baking baked goods such as pizza, onion cake or Plum cake (plum dachi) or the like often creates a crispy and sometimes hard edge. The cutting and slicing of such a bakery, especially with the edge and possibly a covering e.g. B. hard salami slices or other hard garnish, using a knife is then problematic because the hard Edge or the hard surface a particularly intensive sawing work or a lot of pressure on the knife to create it a high cutting or cutting force. If from a pizza on a plate with one off the table uplifting the rim, a piece, especially the hard pizza edge to be cut out and to a knife of usual sharpness is used, so that large Pressure is required when cutting, then there is Danger that the plate can tip over due to this load.

The object of the present invention is therefore a Cutlery to create a safe cut of baked goods such as pizza and the like with little effort allowed to cut the pizza.

According to the invention, this object is achieved by a cutlery solved with the features of claim 1. Beneficial Embodiments of the invention are in the subclaims specified.

Through the cranking of the legs and the clearly, d. H. depending on the design, a few centimeters arranged above the cutting edges or the cutting surface The lower scissor arm of the open can pivot Scissors easily under an edge z. B. a pizza to be pushed on a flat plate or one Baking tray lies. The user's hand remains ergonomically cheaper above the plate Posture while the lower scissor leg flat on the Plate rests. By cutting with scissors no cutting pressure exerted on the pad. The tipping a plate is thus avoided. These scissors are suitable it is therefore advantageous to cut large areas Bakery and especially for slicing baked goods like pizza when eaten, with a hard pizza rim too can be easily cut into bite-size pieces. The term baking is intended to mean anything baked Grip well, suitable for cutting with scissors, like cakes or pan dishes like omelets and the like.

If on the leg with the undercut one Support plate is provided, handling is facilitated and improved because the support plate is a straight guide of the Scissors under the pizza relieved. Furthermore, with the support plate has an edge of the Baking can be raised flat, what with a scissor tip due to the slight penetration of the tip in a soft floor is insufficient. A there is a particular advantage when consuming the baked goods, because one separated with the cutting edges and on the Piece of pizza lying on the support plate and raised from the plate can then be grasped by hand. When using a The support plate serves as a solid base and Counterforce when piercing with the fork, what with a Underlay made of soft material (e.g. polystyrene plate) is advantageous.

The size and shape of the support plate is according to that Purpose specified. With a small support plate can cut chunks of portioned portion be while a large support plate for example for slicing a large pizza or one Onion cake in pieces ready for sale is suitable. The Length of the cutting sections and the cutting is also Customizable according to the purpose.

The arrangement of the handles above the cutting plane in bent back towards the middle section and for example approximately parallel to the cutting plane allows an ergonomic hand position when cutting open, especially when used as cutlery. The Design of the handles can be for right and for Be left-handed adapted, with the support plate at the hand scissors for the left-hander from the cutting section points to the user.

The two legs can be designed in this way and to each other be arranged so that the upper edge either the side of the undercut facing away from the support plate or on the side of the undercut facing the support plate is moved so that the cutting edge on the right or left side of the undercut is.

The articulation at the pivot point can be made detachable be so that the two legs are separated can be. If the support plate has a side knife edge and the other leg molded forks has, the two legs like knife and fork can be used as normal cutlery.

A blocking device is expediently provided, which can prevent opening of the two legs and thus serves as a child lock. For example, it contains an eccentric lever on one leg to lock the other leg or it blocks the articulation against twisting.

If the cutting sections of the two legs light are bent against each other, so the two cutting edges slide to each other under elastic tension. This offers one sharp cut and self-sharpening of the cutting edges.

A cutlery set according to the invention is in the form of hand scissors 1 trained the two on a common rotary or Joint point 2 pivotally connected legs 3 and 4. The first, for right-handed use the left leg 3 facing the user has on his Handle end 5 an eyelet-shaped handle 6 for a thumb right hand as the top scissor handle. The Handle end 5 goes into a central or joint section 7 about (see Fig. 3), which compared to a conventional Scissors that are essentially straight legs (such as a Paper scissors), is bent downward, for example with a slight bend at an obtuse angle according to the Representation in the figures or approximately up to one right angle with rounded transition.

The pivot point 2 of the scissors is in the upper area of the Middle or joint section 7 approximately in the transition to Handle end 5 arranged. At the middle section 7 closes a cutting section 8, which is at an angle, e.g. B. about 70 to 90 °, relative to the central section is bent upwards and is essentially horizontal (For a position of use of the scissors, see Fig. 1 and 3) extends forward to scissor tip 9. Which Cutting section 8 tapering forward in height has a sharpened upper edge as the undercut 10 of Scissors 1 open. This undercut 10 can differ from the central section 7 about a rounding in a transition section 11 extend up to the middle section 7.

The second or right leg 4 has at its handle end 12 an eyelet-shaped handle 13 for index and middle fingers (if necessary also the ring finger) the right Hand as the lower scissor grip. The handle end 12 merges into a central or hinge section 14, which the Middle section 7 of the first or left leg 3 comparable is shaped. The pivot point 2 is more comparable Way in the upper section of the central region 14 in Transition to the handle end 12 arranged so that at closed scissors an approximately congruent arrangement of the two middle sections 7, 14 results.

Via a forward transition area 15 is a front cutting area 16 to the Middle section 14. A rear or bottom edge of the Middle section 14, the transition area 15 and the Cutting section 16 forms a curved upper cutting edge 17 of the scissors 1. The upper edge 17 and the Undercuts 10 are closer to the pivot point 2 in their lying inner sections so curved that in an open scissor position (as shown e.g. in Fig. 3)), which is a receiving and cutting position for z. B. corresponds to a hard edge of a pizza that interacting cutting edge points or sections (inner cutting area 18 and 19) parallel or have approximately parallel tangents, so that the one Baking to be cut from the scissors to the front pressing force component is largely avoided.

This leg design results in the Figures shown cranked scissors shape, in which the Cutting and thus the surface or level of the clippings opposite the handle ends and in particular the pivot point 2 are offset by about 6 to 7 cm, this measure to optimize the lever arms and the Cutting forces for different applications as well as for an ergonomic design can be varied accordingly.

The first or left leg 3 also contains its cutting section 8 has a flat support plate 20 (see Fig. 4) on the underside 21 of the cutting section 8 is formed and in the shape of a Cake server on the side facing away from the second leg 4 Side (the left side of the scissors facing the user) horizontal and therefore approximately at right angles to the cutting section 8 extends. An outer edge 22 of the support plate 20 can be sharpened as a cutting edge so that it can be used as Cutting knife can be used. The support plate 20 can with a z. B. rounded front end 23 over extend the undercut 10 forward so that the Front end 23 can be easily pushed under a pizza rim can and the edge then on the pulled down front section 24 the undercut 10 can slide on.

At the pivot point 2, the two legs 3, 4 are with one Bolt or screw can be rotated as a joint connection connected with each other. The articulation can be used as releasable screw or plug connection be formed, so that the two legs 3, 4 easily detached from each other can be. The leg having the support plate 20 3 can then be used as a knife.

The other leg 4 can be designed as a fork (see Fig. 5). For this purpose, for example Front end 25 of leg 4 a plurality of fork tines 26 provided that either integrally with the leg 4th are formed or as a plug-on part on the leg 4 are attachable.

Furthermore, the scissors can have a blocking device 27 have to the two scissor legs 3, 4 in one keep locked position locked to each other. The Blocking device 27 thus serves as a child safety device. she can have differently designed sliding bolts 28 or 29 (See Figs. 6 and 7) included on one Scissor legs are slidably mounted and in one Hold the other scissor arm in the latch position, see above that both legs are not pivoted relative to each other can be. The sliding bolt 29 shown in FIG. 7 is slidably mounted on the left leg 3 and engages with a pin in an elongated hole 30 on the right Leg 4. In the position shown, the scissors be opened.
