Description

The present invention relates to a grater having a large number of protruding blades formed on the surface of a metal plate.

The grater is used as a cooking utensil to grate vegetables such as radish and carrot, and condiments such as ginger and wasabi. There are various types and forms of graters depending on the application, and graters made of general metal have protruding blades that stand out by punching out a thin metal plate. Copper, aluminum, and stainless steel are used as the metal sheet, and some metal sheet is plated.

In particular, the grater used by professional chefs is made by manually digging up the blades one by one using a tool called a chisel and a mallet on a copper plate. When grated radish, wasabi, etc. are grated with this grater, the sharpness is sharpened by the eyes of the grater, so the fibers can be cut into small pieces instead of being crushed, and since they contain a moderate amount of water, they are fluffy and fresh. It is evaluated as.

As such a grater that can be used by professional chefs, Japanese Patent No. 1246818 (Patent Document 1) and Utility Model Registration No. 3131845 (Patent Document 2) refer to Patent Document 2 without the manual work of craftsmen. It is described that it is manufactured by mechanical means. In the method of manufacturing a grater disclosed in Patent Document 1, a mechanically operated claw attachment is repeatedly advanced and stopped with respect to the grater so that claws arranged in the same row are individually engraved. On the other hand, also in the grater disclosed in Patent Document 2, it is described that a plurality of protruding blades are formed on the grater surface of a composite metal material using copper as a base material.

Japanese Patent No. 1246818 Utility Model Registration No. 3131845

The graters disclosed in Patent Documents 1 and 2 are all graters in which claws are arranged and engraved in the same row on the surface of the grater, and are the same as graters having claws manually formed by craftsmen. Is. In this way, the grater with the claws lined up in the same row is formed by engraving a claw attachment that is substantially equivalent to a wasabi from one direction or the opposite direction. For example, radishes and wasabi are grated only by the nails. For this reason, the grate efficiency is low and the number of times until the desired amount is grated increases, and many complaints have been received from users that they feel tired when using the grater.

The problem to be solved by the present invention is to provide a grater capable of increasing the efficiency of grate and reducing the number of times by using a protruding blade composed of a large number of claws and jetty blades standing on the surface of a metal plate. It is in.

In order to solve the above problems, the invention according to claim 1 is a grater having a large number of protruding blades formed on the surface of a metal plate, and the protruding blades are a claw that stands up in a substantially triangular pyramid shape and the claw. The gist is that the jetty blades of a predetermined height formed between the claws are provided, and the claws and the jetty blades are arranged alternately.

Further, the invention according to claim 2 is the grater according to claim 1, wherein the jetty blade is formed by intersecting a plurality of rows and columns on the surface of the metal plate, and the rows and columns intersect. The claws are formed at each position.

Further, in the invention according to claim 3, in the grater according to claims 1 and 2, the height of the top of the claw from the surface of the metal plate is made higher than the height of the top of the jetty blade. There is.

Furthermore, in the invention according to claim 4, in the grater according to claims 1 and 2, the grater is separated from each other so that a gap is formed between the claw and the jetty blade.

Further, the invention according to claim 5 is the grater according to claims 1 and 2, wherein the jetty blade has a substantially saw blade shape in cross section, and one side surface with respect to the surface of the metal plate. The inclination angle of is formed to be an obtuse angle, and the inclination angle of the other side surface is formed to be an acute angle.

According to the present invention, on the surface of the metal plate, a large number of protruding blades are formed in which claws standing up in a substantially triangular pyramid shape and jetty blades having a predetermined height are alternately arranged between the claws. Because the sharpness of the nails that stand up in a substantially triangular pyramid shape is sharp, for example, if you grate radish or wasabi, you can cut the fibers into small pieces instead of crushing them, and you can grate the fluffy radish that contains moderate moisture. It becomes possible to grate. Moreover, a jetty blade is formed between the claws, and since this jetty blade grate thinly without crushing fibers such as radish, the efficiency of grate can be improved, so that the number of times can be reduced. The feeling of fatigue of the user can be significantly reduced.

Further, since a plurality of rows of jetty blades are formed on the surface of the metal plate and the rows and columns are crossed and claws are formed at the positions where the rows and columns intersect, for example, radish and wasabi, etc. When the grater is grated, the grater can be grated not only in the front-rear direction but also in the left-right direction in the same manner. Therefore, the efficiency of the grate is improved and the number of grate can be reduced.

Furthermore, since the gap is formed by separating the claw and the jetty blade, the sharpness of the claw and the grate function of the jetty blade are independent, so that fibers such as radish are not crushed. It is possible to grate efficiently.

Further, by forming the inclination angle of the other side surface of the jetty blade at an acute angle, for example, radish and wasabi are grated thinly, so that the fibers such as radish can be grated without being crushed.

A grater in which a large number of protruding blades are formed on the surface of a metal plate has a claw in which the protruding blade stands up in a substantially triangular pyramid shape and a jetty blade having a predetermined height formed between the claws. The claws and jetty blades are arranged alternately.

Hereinafter, the grater according to the present invention will be described in detail with reference to the drawings. FIG. 1 shows a grater 1, and the metal plate 2 used for the grater 1 is made of copper, aluminum, or stainless steel, which is used as a general grater. The plate thickness of the metal plate 2 is preferably 0.5 mm to 2.0 mm, and these metal plates 2 may be plated. Further, the grater 1 is formed in the same shape as a generally used grater, and a grip portion 1b extends to one end side of the main body portion 1a. A large number of protruding blades 3 are formed on the surface of the main body 1a.

As shown in FIGS. 2 and 3, the protrusion blade 3 is composed of a claw 3a and a jetty blade 3b, and the jetty blade 3b is formed on the surface of a metal plate 2 by intersecting a plurality of rows and columns. There is. Further, 3a claws are formed at positions where the rows and columns of the jetty blades 3b intersect. The claws 3a are formed upright in a substantially triangular pyramid shape, and the apex is sharply pointed. As shown in the figure, the claws 3a formed upright at the corners of a quadrangle are slightly inclined so as to face outward. There is.

Further, the jetty blade 3b formed between the claws 3a has a substantially triangular cross-sectional shape like a saw blade. In this triangular shape, the inclination angle of one side surface is formed at an obtuse angle with respect to the surface of the metal plate 2, and the inclination angle of the other side surface is formed at an acute angle. Further, as shown in FIG. 5, the jetty blade 3b formed between the two claws 3a forms a gap G so as to be separated from each of the adjacent claws 3a. Then, as shown in FIG. 5, the height H1 of the top of each claw 3a from the surface of the metal plate 2 is formed to be higher than the height H2 of the top of the jetty blade 2b.

Next, a method of forming the protrusion blade 3 including the claw 3a and the jetty blade 3b formed on the grater 1 will be described with reference to FIG. The metal plate 2 serving as the base material of the grater 1 is selected from copper, aluminum treated with aluminum, and stainless steel. The metal plate 2 has a plate thickness and size equivalent to that of a general grater 1, and is placed on a processing device (not shown). After that, as shown in FIG. 5, the claw 3a and the jetty blade 3b are formed upright by the digging tool 5.

In the digging tool 5, a blade portion 5a perpendicular to the moving direction is formed at the tip on the bottom surface side, and the width thereof is set to the width of the protrusion blade 3 formed on the grater 1. Further, the digging tool 5 is tilted at a predetermined angle θ1 so that the rear end side is higher than one surface of the metal material 1 and is attached to a drive device (not shown). The inclination angle θ1 is set to approximately 10 to 30 degrees. Further, the angle θ2 between the sliding contact surface 5b of the digging tool 5 and the moving direction is set to approximately 30 degrees to 80 degrees.

First, as shown in FIG. 5A, the blade portion 5a of the digging tool 5 is brought into contact with the position where the jetty blade 3b of the protrusion blade 3 of the metal plate 2 is formed, and then the digging tool 5 is specified by a drive device. When the metal plate 2 is penetrated at the angle θ1 of the above, the blade portion 5a of the digging tool 5 bites into one surface of the metal plate 2, and the jetty blade 3b is formed upright. The height H2 of the jetty blade 3b is preferably about 0.3 mm to 1.0 mm.

Next, the digging tool 5 is returned to the origin position, the metal plate 2 is advanced to a position where the next jetty blade 3b is formed upright, and the digging tool 5 is brought into contact with the position, and then, as shown in FIG. 5 (B). As shown, when the digging tool 5 is inserted into the metal plate 2 by the driving device at a predetermined angle θ1 in the direction indicated by the arrow, the blade portion 5a of the digging tool 5 bites into one surface of the metal plate 2, and FIG. The next jetty blade 3b is formed upright at a position separated from the jetty blade 3b formed by (A). The distance between the two jetty blades 3b formed in this way is approximately 5 mm to 10 mm. After that, the origin return of the digging tool 5 and the advancement of the metal plate 2 are repeated until the length at which the protrusion blade 3 should be formed is reached.

After that, the direction of the metal plate 2 formed by the multi-row jetty blade 3b standing upright is reversed by 180 degrees. Then, as shown in FIG. 5C, the jetty blade 3b in the opposite direction is formed upright at the intermediate position of the jetty blade 3b formed by the above-mentioned step. The step of forming the jetty blade 3b upright is the same as the step according to FIGS. 5A and 5B described above. In this way, the cross sections of the multi-row jetty blades 3b having different orientations are formed in a substantially saw blade shape. Further, as shown in the figure, the jetty blade 3b has an obtuse angle of inclination of the side surface of the metal plate 2 that is in sliding contact with the sliding contact surface 5b of the one digging tool 5, and the other side surface is inclined. The angle is formed at an acute angle.

In this way, after the jetty blades 3b having a large number of different directions of 180 degrees are formed upright, the direction of the metal plate 2 is rotated by 90 degrees. Then, as shown in FIG. 5 (D), the digging tool 5 is pushed into the jetty blade 3b and the metal plate 2 by the driving device from the direction perpendicular to the jetty blade 3b in the direction indicated by the arrow inclined at an angle θ1. As a result, the jetty blade 3b stands up and the claw 3a stands up. Further, by biting into one surface of the metal plate 2, the jetty blade 3b is formed upright between the adjacent claws 3a. As a result, the height H1 of the top of the claw 3a is formed higher than the height H1 of the jetty blade 3b. After that, the upright forming step of the claw 3a is repeated at predetermined intervals by the digging tool 5.

Next, the direction of the metal plate 2 is reversed by 180 degrees, and as shown in FIG. 5 (E), the claw 3a is formed upright from the direction perpendicular to the jetty blade 3b. At this time, the position where the claw 3a is uprightly formed by the digging tool 5 is an intermediate position of the claw 3a which is uprightly formed by the previous step shown in FIG. 5 (D). Then, by forming the claw 3a upright from the jetty blade 3b, the claw 3a and the jetty blade 3b are separated from each other so as to form a gap G. Then, by repeating the step of forming the upright of the claw 3a, as shown in FIG. 2, jetty blades 3b are formed on the surface of the metal plate 2 by intersecting a plurality of rows and columns, and the rows and columns are formed. Claws 3a are formed upright at the intersecting positions.

FIG. 6 shows a step of forming the grater 1 of the second embodiment according to the present invention, and the jetty blades and claws of the protrusion blades are reduced as compared with the above-mentioned grater embodiment. As the metal plate 11 used for the grater 10, the same copper, aluminum, and stainless metal plates as in the above-described embodiment are used. First, after mounting on a processing device (not shown), as shown in FIG. 6 (A), the protrusion blade 12 composed of the claw 12a and the jetty blade 12b is uprightly formed by the above-mentioned digging tool 5.

First, as shown in FIG. 6 (A), after the blade portion 5a of the digging tool 5 is brought into contact with the position where the protruding blade 3 of the metal plate 2 is formed, the digging tool 5 is driven by the drive device in the above-described embodiment. When the metal plate 11 is inserted into the metal plate 11 at the same predetermined angle as the above, the blade portion 5a of the digging tool 5 bites into one surface of the metal plate 2, so that the jetty blade 12b is formed upright. The height of the jetty blade 12b is about 0.3 mm to 1.0 mm, as in the above-described embodiment.

Next, after returning the digging tool 5 to the origin position, the metal plate 2 is advanced to a position where the next jetty blade 12b is formed upright, the digging tool 5 is brought into contact with the position, and then the digging tool 5 is driven. When the metal plate 2 is inserted into the metal plate 2 at a predetermined angle by the device in the direction indicated by the arrow, the blade portion 5a of the digging tool 5 bites into one surface of the metal plate 2 and is separated from the jetty blade 3b formed upright earlier. The next jetty blade 12b is formed upright at the position. The distance between the two jetty blades 3b that are formed upright first and next is about 5 mm to 12 mm, but it is desirable to make the distance slightly shorter because the jetty blades 12b and the claws 12a are reduced. After that, by repeating the return to origin of the digging tool 5 and the advancement of the metal plate 2 until the length at which the protrusion blade 12 should be formed is reached, a large number of jetty blades 3b stand in parallel on the surface of the metal plate 2. It is formed.

After that, the direction of the metal plate 2 is rotated by 90 degrees. Then, as shown in FIG. 6B, when the digging tool 5 is inserted into the jetty blade 12b and the metal plate 2 in the direction indicated by the arrow from the direction perpendicular to the jetty blade 12b, the jetty blade 12b stands up. Then, the claw 12a is formed upright. Further, by biting into one surface of the metal plate 2, the jetty blade 12b is formed upright between the adjacent claws 12a. The height of the top of the claw 12a thus formed is formed higher than the height of the jetty blade 12b. After that, the jetty blade 12b formed upright by repeating the upright forming step of the claw 12a at a predetermined interval by the digging tool 5 is formed by intersecting the rows and columns, and at the position where the rows and columns intersect. , Each claw 12a is formed upright.

As described above, also in the grater 10 of the second embodiment, as in the above-described embodiment, a large number of protruding blades 12 are formed on the surface of the metal plate 2, and the protruding blades 12 stand up in a substantially triangular pyramid shape. It has a claw 12a and a jetty blade 12b having a predetermined height formed between the claws 12a, and the claws 12a and the jetty blade 12b are alternately arranged. Further, the jetty blade 12b is formed by intersecting a plurality of rows and columns on the surface of the metal plate 2, and claws 12a are formed at positions where the rows and columns intersect. Further, the height of the top of the claw 12a from the surface of the metal plate 2 is higher than the height of the top of the jetty blade 12b. Furthermore, the claw 12a and the jetty blade 12b are separated from each other so as to form a gap.

The grater of the second embodiment can be manufactured in two steps of forming a large number of jetty blades 12b with respect to the metal plate 2 and then rotating the metal plate 2 by 90 degrees to form the claws 12a upright. It is possible to reduce the cost. On the other hand, in the grater of the second embodiment, the number of claws 12a and the jetty blade 12b is smaller than that of the above-described embodiment, and the efficiency may be lowered, but the distance between the jetty blades 12b formed upright is narrowed. It is possible to solve the problem by doing so.

The present invention described above is not limited to these examples, and can be variously modified without departing from the present invention. In the above-described embodiment, the jetty blades composed of a plurality of rows and columns are crossed at right angles to the surface of the metal plate, but for example, they may be crossed at an angle of 30 degrees or 60 degrees. Further, the heights of the jetty blade and the claws to be formed upright may be changed as desired depending on the object to be grated. If the top of the nail is sharp and may cause harm to the user, the top may be blunted by pressing or scraping.
