Description

[Detailed description of the invention] Purpose of the invention [Field of industrial application] This invention relates to a sharpener for sharpening the blades of kitchen knives and the like.

[Problems to be solved by conventional techniques and inventions] Conventionally, in this type of blade sharpener, one or more sharpening members are arranged side by side facing each other, and one blade sharpening port is provided between them. It was just being exposed to it.

Therefore, only the portion of each sharpening member corresponding to the blade sharpening opening was worn out, and the portion that had never been sharpened was not effectively utilized.

The purpose of the present invention is to provide a plurality of blade sharpening ports using three or more sharpening members, thereby reducing local wear of each sharpening member and effectively utilizing each sharpening member.

Structure of the invention [Means for solving the problem] In order to achieve this object, the present invention is provided with three or more sharpening members 7, as shown in the drawings of the embodiments described later, and two of each of the sharpening members 7 are Above sharpening member 7
are combined with each other and a plurality of blade sharpening holes 12a, 12b, 12c are provided between them.

[Function] And, for example, one of the blade sharpening ports 12
You can insert a blade into a and sharpen it. The same applies to the other blade sharpening ports 12b and 12c.

[Example] An example of the present invention will be described below with reference to the drawings.

As shown in FIGS. 1 to 3 and 5, the case 1 consists of a circular bottom plate 2 and a circular cover plate 3 fitted on the outer periphery of the top surface of the bottom plate 2. On the bottom surface of the bottom plate 2, there are many suction cups 2a. It is attached. Three circular support holes 4 with the same inner diameter are provided in the center of the cover plate 3.
They are arranged at 120 degrees symmetrical positions with the center of the center as the center of point symmetry, and communicate with each other near the same center.
Each support hole 4 is located in the center of the upper surface of the bottom plate 2 in the case 1.
A support pin 5 having a circular cross section is provided to protrude upward corresponding to the center of the
is wrapped.

As shown in FIGS. 3 and 6, the three sharpening members 7 are made of ceramic and are molded into the same shape and size, and an insertion hole 8 with a circular cross section is formed in the center of the lower surface of the member so as to extend vertically. At the same time, a regular hexagonal locking flange 9 is provided protruding from the entire outer periphery of the lower surface. The upper surface 10 of each sharpening member 7 has a hemispherical shape, and the outer peripheral surface 11 of each sharpening member 7 from this upper surface 10 to the locking flange 9 has a circular cross section.

Each sharpening member 7 is fitted into each support hole 4 of the case 1, and a support pin 5 is inserted into the insertion hole 8 of each sharpening member 7.
is placed on the compression coil spring 6 in the inserted state. Due to the biasing force of the spring 6, the locking flange 9 of each sharpening member 7 is rotated at the lower edge 4a of each support hole 4.
is pressed against. As shown in FIGS. 1 and 4, each sharpening member 7 is arranged at 120 degree point symmetry with the center of the cover plate 3 as the center of point symmetry so that the line connecting the centers of the insertion holes 8 forms a substantially equilateral triangle. provided, each sharpening member 7
The outer peripheral surfaces 11 of the sharpening members 7 are in contact with each other, and the locking flanges 9 of the sharpening members 7 are in contact with each other to prevent relative rotation.

The contact position of each locking flange 9 can be changed in various ways by removing the cover plate 3 and changing the position of the sharpening member 7 with respect to the support hole 4 thereof.

By installing the three sharpening members 7 in this way, the three sharpening holes 12a, 12 can be formed between the upper surfaces 10 of the respective sharpening members 7 by combining them with each other.
b, 12c can be provided, and for example, the blade can be sharpened by inserting the blade into the blade sharpening opening 12a of one of them. The same applies to the other blade sharpening ports 12b and 12c.

Therefore, each sharpening member 7 can effectively utilize three locations, and local wear can be reduced.

Furthermore, since the combination of the locking flanges 9 of each sharpening member 7 shown in FIG. 4 can be changed in various ways,
Local wear of each sharpening member 7 is further reduced.

In the above embodiment, the three sharpening members 7 are arranged so that the lines connecting their centers form a substantially regular triangle as described above, but four or more other sharpening members 7 are arranged so as to form a substantially regular polygon. It may be arranged as follows.

Further, each sharpening member 7 may be electrically given a slight vibration.

Effects of the invention According to the invention, since a plurality of blade sharpening ports 12a, 12b, 12c are provided by three or more sharpening members 7, local wear of each sharpening member 7 is reduced, making each sharpening member 7 effective. It can be used for.
