The invention relates to an eating utensil which combines the capabilities of a fork, characterized by function for spearing the food and of a knife characterized by function for cutting the food and can be used by the handicapped and people with decreased functional ability of one of their upper limbs. The eating utensil consists of a handle (1) and a head (5) with formed static spearing tines (9) and mounted rotating cutting tines (8') and (8"). The handle (1) has a cavity in which a semi-automatic reciprocal spring mechanism (2) is inbuilt. In outer circumferential surface of the handle (1) are formed slots (1') and sliders with ergonomic shape are placed in them for right (3') or for left (3") handed use. When the utensil is positioned laterally for cutting up the food the place of the slider (3'), (3") coincides with the abutment contact surface of the index finger of the user over the handle (1). The slider (3'), (3") is connected to the contact surface of the mechanism (2) and projects the pressure force from the user's index finger as translational motion into the mechanism (2). The rotating part of the mechanism (2) inside the handle (1) is connected to a transmission (4), inbuilt into the handle (1) and head (5) of the utensil. The transmission (4) consists of a monolith flexible shaft, bent in the middle making a turn and twisted at 90 degree relative to the bending plane, thus forming a loop (4') inside handle's neck. Generated rotational movement at 180 degree from the mechanism (2) is projected over contact surface of the loop (4') and transmitted to the two active ends of the transmission (4), placed in holes (6') and (6") of the head (5). The active ends of the transmission (4) are connected with bearing shafts (7') and (7") of rotating cutting tines (8') and (8") mounted to the frontal side of the head (1) in holes (6') and (6"). The inner longitudinal sides of the rotating cutting tines (8') and (8") are shaped as blades for cutting and can rotate bi-directionally by 180 degree. |
