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. |

1. An eating utensil which includes handle (1) and a head (5), characterized in that the handle (1) has a cavity in which a semi-automatic reciprocating spring mechanism (2) is inbuilt and the outer circumferential surface of the handle (1) has slots (1′) for slider (3′) and (3″), whose location on handle (1) coincides with the abutment contact surface of the index finger of the user in lateral position of the utensil, and is connected to the contact surface of the mechanism (2), the rotating part of which is attached to transmission (4) inbuilt into the handle (1) and the head (5) preserving the classical ergonomic shapes of the utensil, transmission (4) consists of monolith flexible shaft, bent in the middle, making a turn and twisted at 90 degree relative to the bending plane forming an loop (4′) insight handle's neck which is in direct relation with the rotating part of the mechanism (2), and two active ends of the transmission (4) inbuilt inside holes (6′) and (6″) of the head (5) which are connected with the bearing shafts (7′) and (7″) which are monolith part of rotating cutting tines (8′) and (8″) mounted into the frontal side of the head (1) in holes (6′) and (6″) which ensure the 180 degree bi-directional rotation of the rotating cutting tines (8′) and (8″) with their longitudinal internal sides shaped for cutting, facing the middle static tines (9) of the head (5) at initial position. |
