As its name suggests, protection is intended to protect the operator's fingers protect from being injured by the knife, which is why its size cannot be chosen arbitrarily either can, but to the diameter of the cutting knife: · must be matched. In recent times one has gone over to to make such cutting machines collapsible so when not in use ^ in normal protection, especially kitchen drawer, can be accommodated. However, it was criticized that the slide with the finger protection a relatively bulky part and much too much in relation to the entire folded machine Takes up space.

The object of the present invention is to reduce the space required by the slide with the finger guard. To solve this problem, with a-susasiuenklappbare-. Cutting machine of the type mentioned proposed according to the invention that the finger protection at least partially against its lower Part or the slide is foldable and can be locked or fixed at least in the working position. Of course you could also build xhn from two "individual parts, which are then put together for use. Overall As a result of these designs according to the invention, a relatively small, easy-to-handle, light one results for storage part to be accommodated. The foldable version has the advantage that it can be quickly brought into use position un'd relative is stable. Whether you fold the finger guard as a whole towards the slide or just the one in the position of use The uppermost part of the finger protection folds down against its lower part Hn, depends on the construction of the slide and ping protection in detail. The size can also be decisive for this

the folded one. Very. ". / - Its dmäcChine for locking or determination sir" ?, to no special rules, so that all suitable for this purpose and known -'erriegelungs- and locking devices are usable. It is only important that the lock cannot release itself and that a rigid position of use of the finger guard is guaranteed.

In the case of a cutting machine with a slide made of plastic, it is particularly advantageous that a push-button-type lock is provided to fix or lock the foldable parts of the finger guard or the slide and that the snap-in bore and / or the push-button can be elastically pivoted transversely to the direction of folding or are. The elasticity of the walls or wall carrying the push button halves or a push button part is necessary because the snap-in and snap-out movement of the push button is perpendicular to the folding direction of the finger guard or finger guard part.

According to a further rierkmal of the invention, which are in the working position, mutually foldable housings or. Machine parts have a guide slot for the slide and the slide has in particular a T-shaped or angled guide rail engaging the slot, the T-crossbar or the angle leg of the guide rail extending transversely to the knife plane being located below the work surface. By appropriately dimensioning the width of the slot and the dimensions of the guide rail, you not only achieve a smooth movement, but also good tilt security.

In the case of a foldable cutting machine with a support surface for the material to be cut that determines the slice thickness and is movable transversely to the knife plane, it is al>; It is particularly considered that the wall part having the contact surface is resiliently pressed against at least two inclined slideways arranged in a circular arc, in particular rotatable from the outside, and is guided displaceably perpendicular to the plane of rotation. The wall part having the contact surface naturally has corresponding _? support members resting on the associated slide. These are either pins, the free ends of which are pressed onto the slideway by means of the i'eder, or wall-like cams also of a circular arc shape or a thickness that takes into account the curvature. The slideways, which are designed in the manner of an inclined plane, are rotated around their center of curvature by hand or a corresponding adjustment mechanism. Depending on the relative position of the slideway and the support pin or cams, the contact surface for the material to be cut is more or less far removed from a plane laid through the plane of the knife. It performs a pure back and forth movement, which is usually perpendicular to the plane of the knife. A particularly preferred embodiment of this adjustment mechanism is characterized in that the wall part, in particular four sliding cams or sliding pins or the like attached thereto. is supported on four slideways inclined in the same direction, two each lying on a circular cylinder and being arranged offset by 180 and that the two circular cylinders are arranged concentrically to one another and the sliding cams or the like are assigned to them accordingly. By arranging three or, as described here, four slide cams and a corresponding number of inclined slide tracks, you get one

k and anti-tilt adjustment mechanism for the Argyle surface for the wana part exhibiting the material to be cut. Latter are arranged concentrically in pairs, i.e. this device consists of two inner and two outer slideways. Both inside and outside are ax slideways, their beginning and end offset by 180 ° to each other.

When aie slope of each slide extends over 180 °, so the end of each slideway includes at the beginning of av £ same circular cylinder lying at the other slideway. When speaking of circular cylinders in this context, especially when speaking of the sliding cams, it can be an imaginary circular cylinder »The sliding paths form, at least when they extend over an angle of 180 °, at least at their S ¹ UOe a circular ring. If the lowest point of the slideway is also away from the wall that supports it by a certain amount, the circular ring becomes a circular axis with a certain height. In a certain sense, the slideways are to be viewed as crouching, even if the highest cam point is not exceeded here. The concentric arrangement of the pairs of sliding cams has the advantage that you can use very elongated slideways extending over an angle of up to ί80 ° and, despite the slight incline of these slideways, still achieve a considerable lifting height for the contact surface of the material to be cut. The improvement in the stability against tipping can of course only be achieved if the inner slideways are opposite to the. outer arranged offset by a certain angular amount.

The inner chutes are inclined more steeply in a further embodiment of the invention as aie outer and also the heights is ¹ equivalent age of individual points of each slide with respect to each sines starting point for the same angle of rotation of slideways situated on a common zero reference plane or the same. In other words, with the same length or the same design of the sliding pins, the inner slideways must rise more than the outer ones if you want to ensure a permanent contact of all four sliding pins over the entire working angle of rotation - the reason is that the inner slideways are necessarily shorter due to their smaller base diameter or their greater curvature and thus, at the same level for the start and end point, the slope r »sr inner slideways must inevitably be greater than the outer ones. The inner slide tracks are preferably offset by 90 ° relative to the outer and the four slide cams or the like lying on two concentric circles. In other words, this means that the two sliding cams lying on a larger circle, as well as the two sliding cams lying on the smaller inner circle, are offset from one another by 180 ° and that the connecting straight lines between the two inner and the two outer cams are exactly perpendicular stand on top of each other. The slideways are of course arranged in the same way, ie there is a starting point of a slideway every 90 °, with inner and outer starting points alternating.

The slideways rise according to another He characteristic linear, whereby the angle of inclination is smaller or equal to t> ~. Ι / χέοβΓ slope kozünt iiisofeirti special Significant too than they are the self-locking of this adjustment mechanism guaranteed. In order to reduce unnecessary play and ensure that the sliding track and sliding pin are always properly pressed Od. Like. To ensure is in a further embodiment of the invention between which the contact surface for the material to be cut having machine part and designed as a handwheel, the slide bearing part a tension spring, in particular Coiled tension spring, arranged. Of course, a compression spring can also be used with appropriate attachment Find*

iian advantageous embodiment related to this of the invention is that the one tension spring end in a slot of the contact surface for the material to be cut Hash part inserted and through a cross pin is held while the other od in a hole in the handwheel, toggle. The like. And in its hole one Screw is screwed in, the head of which is supported on the handwheel. On the one hand, the spring must be on the inner wall of the iO hole can support and on the other hand, the slope of the individual spring coils must be matched to the pitch of the screw thread. In this case, the inner bore then forms the spiral tension spring has a nut thread for the screw. The spring tension can therefore be regulated and adjusted by turning the screw.

Eiα another feature of the foundation is characterized in that at least part of the cutting knife carrying uehäusekiappteiie is designed as a Kruiüelaaüsicx. Out manufacturing, hygienic and price concerns the housing is now often made of plastic. Often one uses relatively thin walls, which through Cross walls and ribs are stiffened. According to the aforementioned feature, these ribs and transverse walls can now be arranged that a more or less large crumb container is created. Since the formation of the crumbs and their passage downwards can practically not be prevented, this configuration has a beneficial effect in that it prevents these crumbs from hitting and collecting on the table and worktop. The emptying opening of the crumb collector expediently extends transversely to the entry opening formed by the dipping slot in the work surface for the cutting knife. The latter is in continuing education Invention in particular closable by a slide or a flap

"Tiert shown bearing straps i>. The housing is off Made of plastic and consists of relatively thin wall parts, which by corresponding, not shown in detail Ribs are reinforced. These reinforcing ribs have a special feature in the area of the penetration slot 6 for the circular cutting knife 1. They form a crumb trap 8 or a crumb trap located below the work surface V there Crumb bin. The crumbs that inevitably arise during cutting pass through the passage or immersion slot 6 for the cutting knife 1 in the crumb container 8, whose Emptying opening 9 extends perpendicular to the inlet opening. This emptying opening 9 is in the embodiment shown not lockable. The crumb container 8 is collapsed Machine emptied by tilting the housing in the direction of arrow 10 (Fig. 6).

In FIGS. 1 to 5, various embodiments are shown Shown carriage on which the material to be cut is placed. The embodiments of Figs. 1! 5is 4- are collapsible. A first embodiment (FIGS. 1 and 2) of the slide 11 consists of the support plate 12 and the finger protection 13, the latter partly in the direction of arrow 14 Jümklappbar is. In the collapsed, shown in Fig. 1 The state is its dimensions on the folded machine housing coordinated - The folding axis is designated by 15 . The finger guard has an angular cross-section, one angle leg 16 being supported on the cam 17 of the lower finger protection part 18 in the position of use. For pivoting, i.e. for collapsing, this one leg 16 must be bent elastically outwards so that it is at the side the cam 17 can slide past. In the folded state, the longitudinal edge 19 rests on a shoulder 20 of the

terten angle leg 21 c <: s Firiger protection lower part 18 on. The height of the unfolded! Finger protection is selected so that it protrudes beyond the part of the cutting knife 1 protruding beyond the work surface V or is at least as high as possible.

In the slide 22 of FIG. 5, the finger guard 23 can be folded down completely. The folding axis is denoted by 24- and is designed like a hinge * On the whole, the shape of the finger guard in the embodiment according to FIGS. 1 and 2 is the same as that of FIGS.

FIG. 5 shows the arrangement of the slide 25, which can be folded in any way, on the basis of the two schematically illustrated, mutually hinged parts 26, 2? of the machine housing. The arrangement of the folding axis and the design of the two machine housing parts 26, 2V are selected so that a passage and guide slot 28 for the carriage 25 is created. The carriage has an angular guide rail 29 which penetrates the slot and which extends transversely to the plane of the knife extending angle leg 30 below the work surface is located. To support it on the latter, the carriage 25 is also provided with two strips 32, 33.

The wall part carrying the contact surface 34 for the material to be cut is removable or adjustable in the direction of the double arrow 36 (FIG. 10). The adjusting mechanism consists of the component shown in FIG. 9, the rotary dial 38 coupled to it, four sliding cams 39, which are offset by yo ° and made in one piece with the wall part 35, and a tension spring 40 pressing the parts against one another. The component 37 loading

is from the inner ring 40 with the four evenly distributed on the inner circumference of the key grooves 41 for a form-fitting connection with the adjusting wheel 38, ie the arched, wall-like sliding curves 42 to 4, the end faces of which are designed as slideways 46 to 49. The sliding cams 39 of the Vaadt.eil are supported on the latter. Each sliding curve extends over an angle of 90 °, whereby two sliding curves 42, 44 and 43, 45 represent hollow cylinder-like, concentrically arranged structures. At the end of each slide there is a stop 50 which limits the rotational movement. Due to the different diameters or the different curvatures of the slide curves 42 and 43 or 44 and 45, the length of the inner slide tracks 46, 4? shorter than that of the outer 48, 49. Since the height of the sliding cams 39 "viewed perpendicular to the working surface 34- is the same, the incline of the inner sliding paths 46, 47 must be greater in order to ensure that all the sliding cams are in constant contact with their associated slideways than that of the outer slideways 48, 49. Measured from the inner ring 40, the start - and the end point of each slideway as well as equivalent slideway points - for example half the slideway length - are at each level. For example, the slope of the two inner slideways is 5 ° and 37 'and that of the two outer curves is 5 ° 20'. With an angle of rotation of 165 °, this results in a stroke of approx. 16 mm for the wall part 35.The selected angle of rotation of less than 6 ° ensures self-locking of this type of double-thread connection and the angle of rotation of almost 180 ° enables very sensitive adjustment. A four point from the support would of course also be conceivable with four slideways lying on the same diameter, but would have

- 13 -

ui. Embodiment has the disadvantage that the angle of rotation would be small - .3 yO ° and consequently either the self-locking QUQr ₃ would have to be dispensed with or the achievable stroke would be smaller by half.

The sliding cams 39 are also vjand-like, curved parts, two of which are also opposite in pairs and are arranged on different diameters. Instead of wall-like sliding cams, four sliding pins offset by yo ° could also be used, the distance between two opposite sliding pins from the axis of rotation 51 having to be greater than that between the two other sliding pins offset by 90 ° to them. The tension spring 40 is inserted with its one end b2 in a bore 53 of the setting wheel 38. A screw 54 is screwed into its interior, the threads of which engage in the grooves between the individual spring loads and thus generate the spring tension. The other end 55 of the spring 40 is designed like a hook and inserted into a slot 56 of the wall part 35. The cross pin 5V serves to absorb the spring force and to prevent it from being pulled out.

All of the features described and illustrated are essential to the invention.
