is widely believed to be necessary Put on different cutlery on Sundays or on festive occasions than on normal working days. Except for one proportionately large cost factor, which is caused by the fact that a household follows this spreading custom want, is already burdened not insignificantly by the purchase price of a complete additional set of cutlery, arise if such a household maintains several cutlery of the conventional type, further disadvantages. So once must be sufficient Space for the storage of at least two complete cutlery must be made available. But this one is especially with young families, which incidentally also increases the cost of more than just a set of cutlery Eating cutlery can usually not afford, often not available due to a lack of trees. On the other hand, the many parts put a strain Experience has shown that several complete conventional cutlery sets the available capacity to a considerable extent on automatic dishwashers, which often has the consequence that certain parts of the dishes used and / or the For example, taking meals with soiled cutlery by hand instead of in the dishwasher have to be cleaned, whereby the usual course of life is often undesirably impaired.

The invention has for its object to provide a cutlery, in which, while avoiding the disadvantages, known Eating cutlery of the type described with simple and economical means is offered on the one hand with a considerable reduction in the acquisition costs for several meals, different cutlery designs to be able to uncover or designs and on the other hand the capacity of an automatic dishwasher in favor of the inclusion of other parts, such as parts of the dinnerware, of superfluous, space-consuming parts

to relieve.

According to the invention, cutlery is characterized by at least one set of knife and fork and preferably also spoon, which are each assigned to one another in terms of size and handles of the same shape and / or dimensions have, in that at least one further sentence formuud / or dimensionally different designs, among each other but the same handle) »is provided and that the knife blade, fork rake and spoon bowl can each be detached from the associated handle of the one handle set and attached a handle of the further handle set can be releasably fixed.

A particularly simple structural solution results in an expedient development of the invention in that each Handle has a socket for receiving a knife blade, Has fork rake or spoon shell provided plug-in shaft, which after insertion into the respectively assigned socket can be fixed by means of a connecting device on the associated handle.

In this way, according to the idea on which the invention is based, it becomes possible to use only a single one Set of eating tools, namely a knife blade, a fork rake and a spoon bowl, several shape and / or to realize different cutlery in terms of dimensions or in terms of aesthetic design, by replacing the set of eating tools quickly and easily by simply exchanging the one set of handles is completed against a different set of handles to a differently designed cutlery, while the rest notwithstanding the considerable reduction in the necessary costs due to only the necessity, at least an additional set of handles, but not a full

Constantly having to buy more cutlery, including the Tree requirements for the storage of the items from which these two eating utensils are to be created, as well as the available tree to be kept in an automatic dishwasher is significantly reduced

According to a further inventive concept which expediently further develops the invention, the plug-in shaft can be in the receiving socket be durable in each case by means of clamping action. It is preferable to use either on the plug-in shaft or on the receiving socket at least one <^ branch element on one part Spring element can be provided on the other part.

, A preferred embodiment of this is characterized in that the spring moment is formed in that the free end of the plug-in shaft is designed as a pair of spring struts is, by means of which, after its insertion into the receiving socket of the handle, two protruding into the receiving socket East back can be grasped from behind in a non-positive and / or form-fitting manner.

A likewise not obvious alternative solution according to another inventive idea is given by the fact that the plug-in shaft in the receiving socket by means of a screw connection is durable. A screw thread can be preferred on the plug-in shaft or on the end of the handle assigned to it be provided, against which a nut arranged on the respective other part can be tightened. A preferred embodiment this is characterized in that the screw thread is provided as an external thread on the handle and that in each case on the plug-in shaft by means of a radial bead a union nut is kept rotatable, but axially displaceable, which in the course of its screwing onto the external thread on the end of the handle with a radial flange of the plug-in shaft engaging behind the radial bead on the plug-in shaft

"~ t

and handle clamped together in the axial direction. Ferr.er can according to a further inventive development in each case have the part having the screw thread formed by axial slots, which can be brought into a clamping position on the plug-in shaft inserted into the receiving socket by means of the nut that can be brought into an operative connection with the screw thread * Here as with all other solutions with a plug-in shaft that can be held in the receiving socket by means of a screw connection, it has proven to be particularly advantageous if a box element preventing rotation and / or displacement of the plug-in shaft relative to the receiving socket a is provided at the free end of the part having the screw thread.

Another alternative solution according to another inventive development of the invention is characterized in that the The plug-in shaft can be held in the receiving socket by means of magnetic force at least one ferromagnetic element and, on the other part, the course of the magnetic lines of force of the same the joining of the two parts can be provided in a bundled closing counter-element. As aesthetically particularly beautiful and a preferred one has proven to be particularly favorable in terms of production technology Embodiment of this inventive concept proven, which is characterized in that each, the receiving socket has at least one magnetic zone, preferably formed over its entire length from ferromagnetic material is, and that a ring made of magnetically soft material is fixedly arranged on each plug-in shaft, which is preferably in a correspondingly contoured recess in the handle can be lowered.

According to a further expedient development of the invention it can be provided that the plug-in forces of knife blade, fork rake and spoon bowl each have square cross-sectional

have contour, preferably each designed as a square tapering towards its free end, and that the inner cavities of the receiving sockets of the associated handles are correspondingly conical · On these Way is "effected with simple and inexpensive means that on the one hand a rotary movement of the eating tool, namely the knife blade, the fork rake or the spoon bowl, is avoided relative to the handle and, on the other hand, also play in the axial direction between said eating tools and the associated handle is avoided, so that an axial fixation of said eating tools on the handle is guaranteed.

An invention aimed at being as universal as possible Usability perfecting further inventive concept is characterized in that in addition to taking the Cutlery serving meals of larger or smaller dimensions, such as roasting knife, roasting fork or serving fork, Ladle or asparagus or! Cake server or fruit knife, fruit or cheese fork or ice cream or coffee or Dessert spoons or the like are provided, the handles of which with regard to their shape and / or dimensions Design correspond to the handles of the set knife and fork and preferably also spoon and in the same way from knife blade, fork rake or spoon or scoop bowl detachable and on at least one other provided for this purpose in terms of shape and / or dimensions unlike the respective handles of this handle set, the handle of another handle set in are releasably fixable in the same way. Leave that way The advantages of the invention also extend to an expanded set of eating tools or cutlery, so that the transformation possibilities according to the invention are also given for the other parts of a complete conventional cutlery for one person. This is completed

The idea of the invention continues in that in addition to Cutlery of a different shape, such as fish knives, butter or cheese knives, that are used to eat the meal, Fish fork or dessert or cake fork or soup or sauce scoop, are provided, their handles with regard to their shape and / or dimensional design the handles of the set of knife and fork and preferably also spoon and in the same way of knife blade, fork rake or spoon or scoop bowl detachable and at least another design provided for this purpose, different from the respective in terms of shape and / or dimensions Handgrips of this handle set designed handle another set of handles can be releasably fixed in the same way are.

As particularly useful because both manufacture and Warehousing and the sales assortment particularly rationalizing and thereby cost price and / or sales price It has been found to have a beneficial effect when, according to further expedient training, handles of knives with such of forks and / or spoons per handle set interchangeable are trained.

Corresponding illustration, another set of likewise interchangeable handles.

Corresponding parts are identified by the same reference numerals.

The cutlery according to the invention consists of a knife, fork and spoon, each of which is a piece of cutlery of this type Handle 1 of any shape and dimensions and aesthetic design adapted to individual needs has, on which a knife blade 2 (Fig. 1), a spoon shell 4 (Fig. 2) or a fork rake 3 (Fig. 3) as a eating tool is releasably fixable. Preferably, the handles 1 are designed so that they are harmless for a knife, fork or spoon are interchangeable.

As indicated only schematically and in a reduced representation in FIGS. 8, 9 and 10, a further set of handles can be provided with handles 1a of a different shape and / or dimensional design and different aesthetic decoration, which in exchange for the one shown in FIG. 1, 2 3 and 3, the handles 1 of the first set of handles with knife blade 2, fork rake 3 or spoon bowl 4 can be quickly and easily added to a ready-to-use cutlery item or eating utensil. In this case too, ijz + ?. Handles 1a are interchangeable from knife blade 2 to fork rake 3 or spoon bowl 4 and vice versa.

As can be seen from FIGS. 11, 12 and 13, a further set of again differently designed handles can be used 1b can be provided, in which the knife blade 2 or fork rake 3 or «. Spoon bowl 4 detachable

fixable handles are interchangeable.

Referring to Figure 4-, there is "a preferred embodiment of a connector between eating utensils, namely knife blade 2, fork rake 3 "or spoon bowl 4, and handle 1 (or else Handle 1a or Tb) shown, the type of connection in connection with the fixing of a knife blade 2 is explained, the definition of the other eating tools is done in the same way. The handle 1 does not have a closer designated recess, in which an insert sleeve 9 made of ferromagnetic material is arranged and fixed. This magnetic bushing 9 has a blind hole 8 designed, for example, as a very slim square pyramid. For free. At the end of the handle 1, the magnetic socket 9 is sunk so that a receiving cavity 7 is formed will.

As can be seen in FIG. 4, the knife blade 2 (and analogously to this also the spoon shell 4 or the fork rake 3 according to Fig. 2 or 3) each have a plug-in shaft 6, which is one of the contouring of the blind hole 8 in the magnetic socket 9 of the handle 1 has corresponding outer contouring, namely as tapering towards its free end Square, so as a slender square pyramid or a corresponding truncated pyramid is formed. On his Eade close to the knife blade, the plug shaft 6 has a ring 5 fixed to it or to the knife blade 2 magnetically soft material.

If the knife blade 2 is now inserted with its plug-in shaft into the receiving cavity 8 of the magnetic socket 9, arrives the contoured according to the cavity 7 locking ring 5 ia the recess 7 »intended for it, with the plug-in shaft 6 being received in the blind hole 8. If the plug shaft 6 consists of

magnetizable material, so are those of the magnetic socket 9 outgoing lines of force already bundled via the in the Sack-Iocn 8 located plug shaft 6 returned. But even if the plug shaft 6 is made of magnetically hard material, such as stainless steel or stainless steel or the like Material should be formed so that de? Short circuit the magnetic lines of force emanating from the magnetic socket 9 do not take place via the plug-in shaft 6 can, the adhesive effect exerted by magnetic force is brought about by the fact that the bundled Bückführung of said magnetic Lines of force via the specially provided Hing 5 made of magnetically soft material, which in the receiving cavity 7 of the handle 1 is sunk in contact with the annular end face of the magnetic bushing 9 of the handle 1 is located and in this way the knife blade 2 or another eating utensil like · Fig. 2jand 3 holds in its working position, due to the formation of the plug-in shaft 6 and the receiving cavity 8 in the magnetic socket 9 at the same time not only the axial fixing of the eating tool 2 and handle 1, but also the non-rotatability both against each other, with simple and economic Funds is guaranteed «,

In the further preferred one shown schematically in FIG Embodiment of the invention is the definition of the eating tools (shown is the lower part of a Knife blade 2) by means of a clamping effect. For this purpose, the handle 1 has a recess 10 which is suitably shaped Opposite rush back 11 has. The plug shaft 6 of the knife blade 2 (or the corresponding other eating tools in the form of a fork rake 3 or a spoon bowl 4) has a pair of spring struts 12 at its free end, whose outwardly directed contour of the inner contour of the recess 10 in the handle 1 is adapted so that the spring

expand 12 after their introduction into the recess 10 of the handle 1 at least positively, but preferably also positively, each engage behind an associated hasty back 11. The contouring of the pair of spring brackets 12 and associated bast backs 11 on the handle 1 can be made "while maintaining this type of clamping connection that the holding" of both parts is relatively positive to each other Kind of use. Furthermore, the clamping element on the handle 1 and the counter-element on the eating implement 2 or 3 or 4 can also be provided. In the case of a purely form-fitting clamping connection, however, care must be taken to ensure that a release device must be provided, because with a purely form-fitting connection, separation is not possible by simply pulling the eating implement and the handle apart, in accordance with the task on which the two are based. '

The exemplary embodiment of a connecting device shown in FIG. 6 is designed for eating utensils that are particularly stressed by force. The handle 1 also has here a recess 10, which, however, is designed as a cylindrical blind hole and only needs to be relatively short. On the handle 1 spring tongues 13 formed by axial slots 22 are provided towards its free end, the free The end opens into an approximately radially inwardly projecting hammer-like extension 14. The outer sides of the spring tongues 13 form each part of a truncated cone jacket, i.e. in axial section its outer contour runs at an incline to the handle axis. The spring tongues 13 are made of resilient material and have a screw thread on its outer surface.

The plug shaft 6 of the eating tools 2 or 3 or 4 is in turn is cylindrical and has two opposite ends at a suitable distance from its free end

Circular-edge-shaped grooves, so for example two millings in the tangential direction to the cross-sectional circle of the plug-in shaft 6 parallel direction, in which, when the plug-in shaft 6 in the recess 10 of the handle is introduced, the hammer-like projections 14 · the ^ spring tongues 13 can be brought into engagement. This is done for the purpose of fixing the plug-in shaft 6 and handle 1 to each other in that a belonging to the handle 1 and running on the external thread 16 of the spring tongues 13 nut 17 »which contrary to the representation in FIG. 6 also as Handel nut or in any other suitable manner can be tightened. That is because it will open The reason for the conical design of the outer surface and the likewise slightly conical arrangement of the thread Spring tongues 13 compressed, and their haiumerartigeri Projections 14 engage in the grooves 15 in the plug-in shaft 6 and thereby fix this relative to the handle 1 at the same time both in the axial direction and in relation to rotary movements.

The embodiment shown schematically in FIG a connecting device also works with screwing, in contrast to the exemplary embodiment according to FIG. However, the screw nut is not part of the handle, but remains with the respective eating tool 2 or 3 or This embodiment therefore requires less number Nuts, namely one always remaining on this for each eating utensil, and offers the possibility of even larger ones To be able to apply forces during handling.

In this embodiment according to FIG in turn a blind hole-like frontal recess 8, the inner end of which is shaped like a slender square Pyramid is formed. The free end of the handle 1 has a cylindrical external thread 16.

The plug shank 6 of the respective eating tool 2 "or 3 or * ■ is with its free end in connection with a in Fig. 7 "unspecified cylindrical area" than to the shape of the inner area of the blind hole! i8 in the handle 1 complementary Pyramid, so designed as a tapering square. Said cylindrical area is from the eating tool side The rest of the plug-in shaft 6 is separated by a radial flange 20, which is surrounded by an inwardly directed radial bead 19 a union nut 18 is engaged from behind, which is also shown differently than in Fig. 7, namely for example, can be designed as a knurled nut.

It can be seen that when the plug shaft 6 with its pointed square end 21 into the recess 8 in the handle 1 inserted and the union nut 18 is screwed onto the external thread 16 of the handle end, the plug shaft 6 and thus the respectively assigned Eßg'erät 2 or 3 or 4 both in the axial direction and in the direction of rotation the handle axis is positively fixed.

The handles can have other shapes and / or dimensions Have contouring and other aesthetic refinements, as shown in particular in FIGS. 1 to 3 and 8 to 10 and 11 to 13. The handles can as well as the preferred version of the eating tools, namely the knife blade, the spoon bowl and the fork rake, in stainless steel be executed. On the other hand, ceramic, porcelain, marble, glass, staghorn, ivory, gemstone or Semi-precious stone, amber or plastic material or wood with or without a cover, for example made of leather or a combination of two or more of these materials can be used. The eating tools themselves can, provided that this should be desirable for any reason, made of material other than stainless steel, such as plastic material, be educated. In particular, in executions
