Description

The invention relates to a device for protecting the hand, with which a food is kept in a frame during cutting or cutting by means of a knife, wherein the knife is guided in the frame and moved with the other hand.

Such a device is from the DE 20 2010 004 810 U1 known. Here, a frame in the opposite direction in the cutting direction opposite legs each have a longitudinal slot, wherein the slot width (b) is dimensioned so that a knife with its knife thickness (d) in both longitudinal slots can be inserted and moved back and forth and connecting the legs Has web outside a closed support surface for the palm, so that the frame and the food between the legs are durable with one hand when slicing.

The frame is designed as a closed, oval, rectangular or elliptical frame in which the legs are connected to each other on both sides. In another embodiment, the frame has a U-shape. The knife is guided while cutting in the direction of the hand through the longitudinal slot.

It has been shown that when cutting the cutting movement is heavier, the deeper the knife in the food z. B. a roll penetrates.

This has several causes. It is crowded when cutting mass to each side of the knife, which already causes a drag. Next act in the direction of knife, the fixing forces of the hand.

On the other hand, the fixation of the food by hand leads to a slight displacement of the food, with the result of a tension between the knife and frame.

These processes, which complicate the cutting motion, trigger the human reaction to increase the hand's fixation forces, with the result that the cutting motion becomes even heavier.

Similarly, the problems in using the device according to US 2002/0020260 A1 . U.S. 4,807,862 B or EP 0 689 906 A1 In the solution after the EP 0 689 906 A1 Side panels are used, between which the food is fixed by the sheets are pressed together by a hand.

The object of the invention is to enable the slicing of food with such devices without resistance.

This object is achieved with the features of claim 1, advantageous embodiments are the subject of the dependent claims.

According to the invention, in a device for protecting the hand when cutting or cutting food by means of a knife which is guided in a slotted frame, wherein the food is arranged in the frame and is fixed by hand using at least one pressure plate movably mounted on the frame, proposed that the pressure plate is hinged on both sides with one frame part such that a force exerted on the pressure plate force F _{1 has} a displacement of the pressure plate in the direction of the food result and exerted in the plate plane in the cutting direction on the pressure plate force F ₂ a Movement of the pressure plate off the food entails.

As a result of a force shift between F ₁ and F ₂ , the food can in principle be relieved of external forces during cutting, with the result that the cutting process becomes easier.

The articulated connection between the pressure plate and each frame part is preferably formed by a four-membered transmission chain. The articulated members of the articulated connection with the frame part form an acute angle .alpha., The opening of which points away from the hand.

As described above, the processes that make the cutting movement difficult trigger the human reaction to increase the hand's fixation forces, with the result that the cutting motion becomes even heavier. With the above-mentioned angular arrangement of the transmission chain, the conditions are now created that these reaction forces cause the necessary shift to offset between the forces F ₁ and F ₂ . By increasing the force F ₂ , the pressure plate moves slightly away from the food. The force F ₂ increases because the forces transmitted by the fingers of the human hand automatically act more strongly in the force direction F ₂ in the event of an increase in force.

In an advantageous embodiment, the pressure plate on the outside in the lower area facing the palm of a thickening over which grip a finger of a hand or the thumb while holding the frame. This clearly supports the introduction of force into the plate surfaces.

In a further advantageous embodiment, the pressure plate has a curvature to the outside on, so that the food rests against the pressure plate in a trough.

In a further advantageous embodiment, it is provided that the pressure plate is arranged durchschwenkbar through the opening of the frame so that it takes over the task of an ejection device after completion of the cutting process.

The proposed device will be explained with reference to the drawing. Show it:

1 the device in a perspective view,

2 a side view and

3 the mechanical principle.

The 1 to 3 show a device for protecting the hand when slicing or cutting food 3 by means of a knife 2 in a slotted frame 5 . 6 . 9 is led, whereby the food in the frame 5 . 6 . 9 is arranged and by hand using at least one movably mounted on the frame pressure plate 10 is fixed.

The pressure plate 10 is hinged on both sides with one frame part in such a way that one on the pressure plate 10 applied force F ₁ a shift of the pressure plate 10 in the direction of the food 3 entails and one in the plate plane in the cutting direction on the pressure plate 10 applied force F ₂ a movement of the pressure plate 10 away from the food 3 ,

The pressure plate 10 has outside in the lower area facing the palm of a thickening 12 on, over the fingers of a hand or the thumb while holding the frame 6 . 8th . 9 to grab. This promotes the introduction of force into the plate plane with an increase in the fixing forces of the hand, like the 2 and 3 demonstrate.

The articulated connection 11 between the pressure plate 10 and each frame part is here a four-link coupling gear chain 6 . 11 . 11 . 10 ,

The articulated links close the articulated connection 11 with the frame part an acute angle α a, the opening points away from the hand.

The frame part with which the pressure plate 10 is connected on both sides, is the respective frame legs 5 . 6 , but also the jetty 9 be.

In a preferred embodiment, the pressure plate 10 a bulge outwards, leaving the food 3 on the pressure plate 10 in a hollow. Furthermore, the pressure plate 10 on the food 3 facing side roughness 13 exhibit.

Will the pressure plate 10 through the opening of the frame 5 . 6 . 9 arranged swing-through, the pressure plate can 10 take over the task of an ejection device after completion of the cutting process.

In addition to the representation with a pressure plate 10 is also provided on both sides of the frame 5 . 6 . 9 one pressure plate each 10 to arrange.
