  • the cutting device has one in the area of the fork tines arranged knife with a cross to the forks trimmed cutting edge on which in the direction the fork tines can be moved longitudinally and pivoted is.
  • an electric motor is also provided in the housing, which cuts the knife via a gear Swiveling movement mediated.
  • the invention is based on the object Cutlery with a spoon bowl attached to a handle to design such that this with one hand is operable and that with this also a cutting function for crushing pieces of food in a simple way can be executed.
  • the task is according to the invention in the generic cutlery solved by moving the spoon bowl along a ring line is divided so that a self-contained Edge ring with the first stem shaft and an inner one Shell part is connected to the second stem shaft.
  • the inventive design provides a cutlery with which the functions of dividing, picking up the food and feeding it to the mouth can be carried out easily and safely for disabled people.
  • the scissor-like movement of the two parts of the spoon bowl provides an extremely simple cutting method in which it is not necessary to fix the piece of food in any way by means of a second set of cutlery. Above all, however, it is easily possible for the user to also cut dishes such as meat, tough or hard vegetables into bite-sized pieces.
  • the actual cutting edge lies in the crushing of a food essentially in a plane running parallel to the edge of the spoon, so that when the scoop-like closing of the spoon bowl and at the same time keeping the cutlery horizontal, the separated food part automatically comes to rest in the spoon bowl and can be easily passed to the mouth ,
  • This configuration in particular enables extremely simple and easy handling.
  • the arrangement of the scissors joint near the edge of the Spoon bowl according to claim 2 are extremely large Shear forces or cutting forces when crushing food parts applicable what the cutlery of the invention especially suitable for people, such as for example disabled children who do not have appropriate have great hand strength.
  • the arrangement of the spreading spring between the two stem shafts according to claim 4 allows easy assembly and a variable configuration of the spreading spring.
  • the invention Cutlery for the individual needs of a disabled person can be easily adjusted. That's what stem stems are different shapes and sizes with the Spoon shell parts connectable, so that the invention Cutlery, for example, according to the size of the hand or the type of disability of the operator by simply replacing the stem shafts can be chosen.
  • the cutlery not shown in FIGS. 1 to 4 has a in the longitudinal direction on two-part spoon bowl 1.
  • the two shell parts 2 and 3 are each in one piece and rigidly provided with a stem shaft 4 or 5.
  • These two Stem shafts 4 and 5 form in that shown in Fig. 3 closed state of the cutlery a spoon handle 6 and the two shell parts 2 and 3 the closed Spoon bowl 1.
  • the two stem shafts are near the edge of the spoon bowl 1 4 and 5 by a scissor joint 7 with each other connected and thus movable against each other like scissors.
  • the scissor joint 7 consists of two bearing bores 11 and 12, each in one-piece molded bearing eyes 13 and 14 arranged and by a common cylindrical Bearing pin 10 connected to each other in a coaxial position are.
  • a U-shaped is between the two stem shafts 4 and 5 curved, consisting of a flat strip material Spreading spring 15 arranged with an extended Shaft part 16 on the stem shaft 4 is fastened on the inside and with the bent end portion 17 on the inside of the opposite stem shaft 5 is supported.
  • This spreading spring 15 has the task of the two stem shafts apart and the two shell parts Keep 2 and 3 in the open shear state, so at using this cutlery as a cutting tool only the closing and thus the cutting movement by manual Force must be brought about.
  • the stem shaft 5 is with a slidable latch 20 provided with a Locking lug 21 in the swivel range of a locking edge 22 of the shell part 2 protrudes when it is in the in Fig. 3 shown locking position is.
  • This locking option is required to Lock spoon bowl 1 when closed can, if the eating tool is only used as a spoon.
  • FIGS. 5 to 16 inclusive is also a two-part spoon bowl 31 available, but which is not divided longitudinally, like the spoon bowl 1, but along a ring line 47, such that a self-contained edge ring 32 and an inner shell part 33 are formed.
  • the edge ring 32 is in one piece and rigid with one Handle shaft 34 connected and the shell part 33 also integral and rigid with a stem shaft 35.
  • the two stem shafts 34, 35 are close to the edge the scissor joint 37 lying together with the spoon shell 31 connected and therefore also scissors-like against each other movable. So that these two components of the spoon bowl 31 used as a scissor-like cutting tool can be both the edge ring 32 and that Shell part 33 each with a cutting edge 48 or 48/1 provided, which work together like scissors to the Compressing the spreadable by an expansion spring 45 Stem shafts 34 and 35 food in between, for example pieces of meat, vegetables, pastries or the like. to shred.
  • the spreading spring 45 consists of a U-shaped one Bracket between the two stem shafts 34 and 35 is arranged to exert a spreading effect.
  • the swivel axis 18 of the scissors joint 7 perpendicular to the plane of the Spoon bowl edge 19 extends in the cutlery according to the invention 5 and 6, the pivot axis 36 of the scissor joint 37 parallel to the plane of the spoon bowl rim 49 and each transverse to the longitudinal direction of the two stem shafts 34 and 35.
  • a locking device 43 is also provided here.
  • This locking device consists of a locking pin 44, in the longitudinal direction of the stem shaft 35 in an elongated hole 38 of this stem shaft 35 slidably stored and provided with a locking lug 39, the one Locking shoulder 40 of a recess 46 of the opposite Handle shaft 34 engages behind when locking takes the locked position shown in Fig. 5a.
  • the locking pin can be actuated by means of an actuating button 41 44 in slot 38 so far that the Locking nose 39 leaves the locking shoulder 40 and the two Stalk shafts 34 and 35 can be spread like that is shown in Fig. 6.
  • Moving the locking pin 44 from the release position and in the locked position shown in FIG. 5 and vice versa is manual, e.g. B. with the thumb or another suitable finger.
