is tightened to position the adjustment member 6 so that it cannot tilt. Thereafter, the blade e is inserted into the insertion groove 4 between the two connecting members 3 with the cutting edge of the blade facing forward, and the blade e is moved back and forth along the insertion groove 4 while being pressed against the rotary grindstone 11. Then, the blade e is sharpened by rotating the rotary grindstone 11.

(Example) An example embodying the present invention will be described below with reference to the drawings. 1 is a support for a sharpener;
It is formed by a pair of front and rear fixing plates 2 as fixing members having a rectangular shape, and a side plate 3 as a pair of left and right connecting members installed approximately in the upper half between the two fixing plates 2. Reference numeral 4 denotes an insertion groove formed between the side plates 3, which passes through both the front and rear fixing plates 2 and opens at the front and rear of the support body 1. This insertion groove 4 is for inserting a blade e such as a kitchen knife and moving it back and forth. Reference numeral 5 denotes a substantially semicircular recess provided below the insertion groove 4, and is formed by cutting out the lower half of the side plates 3.

Reference numeral 6 denotes an adjustment member provided between both fixed plates 2 below both side plates 3, and its front and rear ends are attached to both fixed plates 2 so that it can be tilted in the left-right direction by a pair of tilting shafts 7. installed. Especially the second
As shown in the figure, 8 is a substantially semicircular recess provided by cutting out the upper side of the adjustment member 6, and forms one circle with the recess 5 on the lower side of the insertion groove 4. . Reference numeral 9 denotes notches formed on the upper surface of both the front and rear ends of the adjustment member 6, as shown in FIGS. 1 and 4 in particular. Reference numeral 10 denotes a pair of left and right support arms protruding from the center of the recess 8 of the adjustment member 6, and protrudes upward from both left and right sides of the recess 8. Reference numeral 11 denotes a disc-shaped rotary grindstone provided between both support arms 10, and is rotatably mounted on a shaft 12 with respect to both support arms 10.

Reference numeral 13 denotes an angle adjustment groove that is transparently provided in the front fixing plate 2 at a position below the front tilting shaft 7, and is formed in an arc shape centered on the axes of both tilting shafts 7. Reference numeral 14 indicates a plurality of scales provided between the tilting shaft 7 and the angle adjustment groove 13, which are used to display the inclination angle of the cutting blade of various cutlery knives such as butcher knives, vegetable knives, paring knives, etc. . Numeral 15 is a bolt whose base end is embedded and fixed in the lower front end of the adjustment member 6, and projects forward from the angle adjustment groove 13 of the fixing plate 2. 1 is a wing nut screwed onto the protruding end of the bolt 15.

By tightening the adjustment member 6 toward the fixing plate 2, the adjusting member 6 can be fixed to both fixing plates 2 so as not to be tiltable.

To use the sharpener for cutlery such as kitchen knives configured as described above, first loosen the wing nut 16, tilt the adjusting member 6 about the pair of tilting shafts 7, and adjust the inclination to the sharpener for the cutlery to be sharpened. Align with the scale 14 corresponding to the cutting edge inclination angle of the blade body e. Then, the wing nut 16 is tightened to position the adjustment member 6 so that it cannot tilt. At this time, since notches 9 are formed in the upper surfaces of both front and rear ends of the adjusting member 6, the upper surface of the adjusting member 6 does not come into contact with the lower surface of the side plate 3.

After doing this, as shown in FIGS. 1 and 3, insert the blade e into the insertion groove 4 of both side plates 3 with the cutting edge facing forward, and insert the blade e into the upper half of the grindstone 11. It is moved back and forth along the insertion hole 4 while pressing against the side surface. Then, the whetstone 11 rotates back and forth about the shaft 12, and the blade e is sharpened as the whetstone 11 rotates.

In addition, when sharpening both sides of the blade body e,
Insert the blade e into the insertion groove 4 in the opposite direction to that described above, that is, with the cutting edge facing backward. Then, press the insertion groove 4 while pressing the blade e against the grindstone 11 in the same manner as above.
Just move it back and forth along the directions to sharpen the blade.

Also, if the sharpener is used as described above and one side of the rotary whetstone 11 is worn down as a result,
The other side surface can be used by tilting the rotary grindstone 11 in the opposite direction (to the left in FIG. 3).

As described above, using the scale 14, the rotary grindstone 11
Since the angle can be set to an appropriate angle, the blade can be sharpened in accordance with the inclination angle of the cutting edge of various cutlery such as kitchen knives and paring knives. Furthermore, the horizontal inclination angle of the rotary grindstone 11 can be set to any angle regardless of the scale 14.

Further, the rotating grindstone 11 is provided on the adjusting member 6, and the adjusting member 6 is attached to a pair of front and rear fixed plates 2.
Since it is provided in between, the whole can be made compact.

Furthermore, the adjustment member 6 is tiltably supported with respect to the fixed plate 2 by a tilting shaft 7, and
The adjustment member 6 is fixed to the fixing plate 2 by the adjustment member 6.
This is done using two parts: the bolt 15 protruding from the top and the wing nut 16 screwed onto the bolt 15, which not only simplifies the overall structure by reducing the number of parts, but also makes manufacturing easier. It is possible to shorten the process and reduce manufacturing costs.

Effects of the invention As detailed above, this invention allows the rotating whetstone to be set at any angle, making it possible to sharpen blades according to the inclination angle of the cutting edge of various blades such as kitchen knives and paring knives. .

Further, since the rotating grindstone is provided in the adjustment member and this adjustment member is provided between the pair of front and rear fixed members, the entire device can be made compact.

Furthermore, the adjusting member is tiltably supported with respect to the fixed member by a tilting shaft, and the adjusting member is fixed to the fixed member by a bolt protruding from the adjusting member and a nut screwed onto the bolt. Since this is done using two members, it is possible to not only simplify the overall structure by reducing the number of parts, but also shorten the manufacturing process and reduce manufacturing costs.
