JP 2003-251549 A

  In the prior art of Patent Document 1, since the knife is moved and polished, it is difficult to polish with high accuracy while maintaining the edge angle over the entire blade edge of the knife. Further, since a sharpening material such as a grindstone is used, not only is it expensive, but if the shape of the polished surface of the grindstone is broken, the polishing accuracy may be further reduced.

  An object of the present invention is to provide a kitchen knife polishing apparatus capable of polishing with high accuracy without requiring skill.

  In order to achieve the above object, the present invention includes a support base that supports a kitchen knife and a polishing tool for polishing the blade edge of the kitchen knife on the support base. On the upper surface of the support table, the cutting edge of the knife protrudes from the upper surface of the support table, and a support surface that supports the blade of the knife at a specified angle in accordance with the blade edge angle and a stopper that receives the base end of the knife of the knife. And a handle is provided on the upper surface of the polishing tool, and a polishing sheet is provided on the lower surface.

  According to said structure, since the blade edge of a knife protrudes from the upper surface of a support stand, and is supported by a support surface at the defined angle according to the blade edge angle, the whole blade edge can be easily and highly accurately using a polishing tool. Can be polished. That is, the polishing operation can be easily performed by the polishing sheet by holding the handle on the upper surface of the polishing tool. Since an abrasive sheet is used as the abrasive, there is no possibility that the shape will collapse, and high-precision polishing can be maintained.

DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments embodying the present invention will be described with reference to the drawings.
As shown in FIGS. 1 and 2, the kitchen knife polishing apparatus of the present embodiment includes a support base 21 and a polishing tool 22.

As shown in FIGS. 1, 3, and 4, the support base 21 is entirely formed of synthetic resin, and a support recess 23 is formed on the upper surface thereof.
The support recess 23 is line-symmetrical with respect to the symmetry axis L. On both sides of the axis of symmetry L, a support edge 24 having a curved shape similar to the peak 102 of the kitchen knife 101 is formed in the support recess 23.

  On the bottom surface of the support recess 23, an inner support surface 25 is formed which is positioned in an inclined state on both sides of the symmetry axis L. On the outer side of the support edge 24, an outer support surface 26 is formed which is positioned on an inclined surface continuous with the inner support surface 25 on the opposite side via the symmetry axis L. Accordingly, the inner support surface 25 and the outer support surface 26 on the opposite side via the symmetry axis L are formed at the same angle on a continuous surface. Stepped stoppers 28 are formed at the base ends of the outer support surfaces 26.

  On the upper surface of the end of the support base 21 located on the side of the stopper 28, projections 27 are formed in line-symmetrical positions on both outer sides of the support recess 23, and the handle 106 of the knife 101 can be disposed between the projections 27. Various intervals are formed.

  As shown in FIGS. 1 and 5, the polishing tool 22 includes a main body 31 made entirely of synthetic resin, and the main body 31 is configured by integrally forming a handle 33 on an upper surface of a substrate 32. On both sides of the lower surface of the substrate 32, curved surface portions 321 that are thinner toward the outside are formed. A water-resistant sandpaper 34 is attached to the entire lower surface of the substrate 32 including both curved surface portions 321 via a double-sided adhesive tape (not shown). This sandpaper 34 constitutes an abrasive sheet.

Next, a method for using the knife polishing apparatus configured as described above will be described.
When the blade 103 of the kitchen knife 101 is polished, the blade 103 of the kitchen knife 101 is placed on the inner support surface 25 and the outer support surface 26 of the bottom surface of the support recess 23 as shown in FIGS. 103 peaks 102 are applied to the support edge 24. Further, the base end 104 of the blade 103 is brought into contact with the stop portion 28. In this way, the blade 103 of the knife 101 is stabilized in an inclined state, and the blade edge 105 is held in a state where it is slightly lifted from the upper surface of the support base 21. In this state, the blade surface of the blade edge 105 is arranged in a state close to horizontal. Further, the position of the base end of the blade 103 is regulated by the stop portion 28. Accordingly, the blade 103 of the knife 101 is held in a stable state in both the width direction and the length direction.

  Then, as shown in FIG. 2, in this state, the handle 106 of the kitchen knife 101 is held with one hand, the handle 33 of the polishing tool 22 is held with the other hand, the sandpaper 34 is wetted with water, and the cutting edge is formed by the sandpaper 34. What is necessary is just to perform the grinding | polishing operation | work with respect to 105. FIG. In this case, since the blade surface of the blade edge 105 of the blade 103 is nearly horizontal, if the polishing tool 22 is moved laterally along the blade surface of the blade edge 105, the blade surface is polished at an appropriate angle. it can.

  When the polishing of one of the blade surfaces of the blade edge 105 is completed, as shown by a two-dot chain line in FIG. 4, the knife 101 is turned upside down and the blade 103 is placed on the other inner support surface 25 and the outer support surface 26. While being installed, the peak 102 of the blade 103 is applied to the support edge 24. Further, the base end 104 of the blade 103 is brought into contact with the stop portion 28. Accordingly, in the same manner as described above, the other side surface of the blade 103 is placed on the outer support surface 26, and the blade edge 105 is held slightly lifted from the upper surface of the support base 21 and held in a state where the blade surface is almost horizontal. Therefore, the polishing operation can be performed in the same manner as described above. Then, the knife 101 is turned upside down again to polish the edge of the blade edge 105 (the portion where the blade edge 105 is bent toward one blade surface by polishing).

In this way, both the blade surfaces of the blade edge 105 can be polished so as to form an appropriate blade edge angle, and a sharp blade edge 105 can be obtained.
Not only the knife 101 but also the knife can be polished in the same manner as described above.

The present embodiment has the following effects.
(1) A support recess 23 for supporting the blade 103 of the knife 101 in a positioned state is formed on the upper surface of the support table 21, and the blade edge 105 of the knife 101 protrudes from the upper surface of the support table 21 and is adjusted to the blade edge angle. The inner support surface 25 and the outer support surface 26 are stably supported at a specified angle. For this reason, the cutting edge 105 can be easily and accurately polished using the polishing tool 22. That is, the blade 103 is stably held by the support edge 24, the inner support surface 25, the outer support surface 26, and the stopper portion 28, and the blade surface of the blade edge 105 is maintained in a nearly horizontal state. For this reason, the cutting edge 105 can be easily and accurately polished by the sandpaper 34 on the lower surface of the polishing tool 22 as described above. Further, since the polishing operation can be performed by the polishing tool 22 having the handle 33, the polishing operation is easier than the case where the knife 101 is subjected to the polishing operation.

  (2) Since the protrusion 27 is formed at the end of the support base 21 on the stop portion 28 side, the hand holding the handle 106 hits the blade 103 of the kitchen knife 101, or the blade 103 of the kitchen knife 101 is the end of the support base 21. It is possible to avoid the movement from the portion to the outside on the handle 106 side, and the polishing operation becomes easy.

  (3) By using a water-resistant sandpaper 34, the blade surface can be polished smoothly and with smooth surface roughness by wetting the sandpaper 34 with water.

  (4) Since the handle 33 is provided on the upper surface of the polishing tool 22 and the sandpaper 34 is provided on the lower surface, the handle 33 can be held with one hand, and the handle 106 of the kitchen knife 101 is held with the other hand. Thus, the polishing operation can be easily performed with little effort.

  (5) Since the sandpaper 34 is used without using a grindstone as an abrasive, the product cost can be reduced. Further, the support base 21 and the main body 31 of the polishing tool 22 can be integrally formed of synthetic resin. Therefore, the manufacturing cost can be reduced. For this reason, it is suitable for selling the knife polishing apparatus of this embodiment with a knife.

  (6) Since the curved surface portions 321 are formed on the lower surfaces on both sides of the substrate 32 of the polishing tool 22, that is, on both sides of the surface on which the sandpaper 34 is adhered, the sandpaper 34 in the same portion is also formed on the curved surface portion 321. It is formed in a curved shape along. For this reason, it can prevent that the sandpaper 34 located in the both sides of the board | substrate 32 hits the blade edge 105 of the knife 101 with a small area. Therefore, tearing and peeling of the paper 34 can be suppressed by the stress concentration on the sand paper 34.

(7) Since the support edge 24, the inner support surface 25, the outer support surface 26, and the stopper portion 28 are arranged symmetrically on both sides of the symmetry axis L, both surfaces of the blade 103 of the knife 101 can be polished with high accuracy.
(8) As described above, since the sandpaper 34 is used as the polishing sheet, unlike the grindstone, there is no fear of the shape being lost, and high-precision polishing can be maintained. In addition, when the sand of the sandpaper 34 is worn out, the sandpaper 34 is simply attached to the substrate 32 with a double-sided tape, so that it can be easily replaced with a new sandpaper 34.

In addition, this invention is not limited to the said embodiment, It is also possible to embody in the following aspects.
-Use sand paper 34 instead of wet type.

-A structure such as a non-slip rubber material is provided on the bottom surface of the support base 21.
-One of the inner support surface 25 and the outer support surface 26 is omitted.
-The curved surface portion 321 of the substrate 32 should be a straight plane. Alternatively, the curved surface portion 321 is omitted.
