Background Art

[0002] Conventional graters have a method of grating food held by fingertips by reciprocating the food against a plurality of claw-shaped protrusions provided on the plate surface, and there is a risk of damaging the fingertips with the claw-shaped protrusions.

[0003] Provide a grater that does not risk damaging the fingertips with the claw-shaped protrusions.

Means for Solving the Problems

[0004] To achieve the above object, a grater in which two spherical crown surfaces with concavities and convexities face each other In a grater that grates food with a plurality of claw-shaped protrusions provided on the surface, A spherical crown outer surface grater in which the surface provided with the claw-shaped protrusions is the outer surface of the spherical crown, and A spherical crown inner surface grater in which the surface provided with the claw-shaped protrusions is the inner surface of the spherical crown are provided, Characterized in that the outer surface of the spherical crown outer surface grater and the inner surface of the spherical crown inner surface grater face each other and are relatively swingable.

Effects of the Invention

[0005] Since the food sandwiched between the spherical crown outer surface grater and the spherical crown inner surface grater is grated by the claw-shaped protrusions provided on the two opposing spherical crown surfaces with concavities and convexities swinging relatively, there is no risk of damaging the fingertips with the claw-shaped protrusions.

Modes for Carrying Out the Invention

[0007] A spherical cap is the spherical portion of a spherical segment, which is a three-dimensional object formed when a sphere is cut by a single plane. Here, the convex outer surface of the spherical cap is called the outer surface of the spherical cap, and the concave inner surface is called the inner surface of the spherical cap. A sphere base is a solid formed when a sphere is cut by two parallel planes, but in this context, it refers to a shape where the center of the sphere is located between the two parallel planes used to cut it. The spherical portion of the ball stand is called the spherical band, and in this context, the concave inner surface is called the inner surface of the spherical band. The claw-like projections only need to protrude from the surface; their shape, such as the angle, direction, and sharpness of the tip, and their number are not limited. Both claw-like projections on the two concave and concave spherical surfaces may be for grating, or one may be a claw-like projection for grating and the other a claw-like projection for holding food. For illustrative purposes, the claw-like projections are depicted larger in the diagram.

[0008] The grater on the outer surface of the cap and the base of the ball are integrated with the centers of each ball aligned, and the tips of the claw-like projections on the outer surface of the cap are located at the positions of the cut spherical surfaces of the base. From the ball base, there is an axis extending in the opposite direction from the grater on the outside of the ball cap, and a handle is attached to the end of this axis so as to be able to rotate around it. The ball base is held within the cylinder in the vertical arrangement shown in the drawing, allowing it to move up and down. Below the cylinder is a stopper with an inner surface that fits onto the outer surface of the ball base, preventing the ball base from moving below that position. This stopper only needs to be narrowed inward from the diameter of the cylinder so that the ball base does not drop below this position, and is not limited to the shape of the inner surface of the ball band. The grater on the inside of the cap is located below the cylinder, at a position where the center of the sphere in the cap coincides with the center of the sphere on the ball stand, which has been lowered to the position of the stopper. The tip of the claw-like projection on the grater on the inner surface of the cap is located at the position of the cut-off spherical surface of the ball base, which has been lowered to the stopper position. The grater on the inside of the cap may be integrated with the cylinder, or it may be removable. Furthermore, a portion of the surface from the spherical inner stopper to the grater on the inside of the cap is open to the outside, serving as an outlet for the grated food. Theoretically, the tips of the two claw-like projections of the grater would be positioned at the cut-off spherical surface of the ball base when it has lowered to the stopper position. However, in practice, the tips of one or both claw-like projections are slightly separated from the cut-off spherical surface of the ball base, creating a small gap between the tips of the two claw-like projections, preventing them from contacting or damaging each other. The ingredients to be grated are placed inside the cylinder, and a spherical grater with an integrated handle and base is placed on top of them. The grater is then swung downwards to grate the ingredients. The spherical outer grater moves down the cylindrical surface, grating the food as it goes until it reaches the stopper. This allows you to grate food completely between the two opposing grooves of the grater, without the risk of cutting your fingertips on the claw-like protrusions. The grated ingredients are discharged sequentially from the ingredient discharge port. In the diagram, the entire surface is shown as a spherical surface to make the shape of the cap easier to understand visually, but grooves can also be added to the spherical surface to discharge the grated food.

[0009] As described above, by oscillating the two opposing graters with protrusions and indentations relative to each other, food placed between them can be grated. Furthermore, a spur gear can be provided around the axis of the outer grater of the spherical cap, and an internal gear can be provided on the inner surface of the cylinder. The teeth of this internal gear are located on the inner surface of the cylinder, and it also functions as a cylinder that holds the ball base. The combination of the two gears and the grater can be reversed. As shown in the diagram, by tilting the spherical outer grater around the center of the sphere and maintaining the state in which the spur gear engages with the internal gear, and rotating the handle around the central axis of the cylinder, the spherical outer grater moves in a miso-grinding motion around the center of the sphere. As the spur gear engaged with the internal gear revolves and rotates on its own axis, the rotation around the axis is added to the miso-grinding motion of the spherical outer grater, allowing for more efficient grating of ingredients. This works on the same principle as a Spirograph. Because spur gears mesh with internal gears at an angle to their axis, they have a shape where the tooth width tapers towards the tip, as shown in the diagram. Spur gears can also be made movable along the axis. [Explanation of Symbols]
