Description

[Detailed description of the invention] Purpose of the invention [Field of industrial application] This invention relates to a case for storing cutlery such as kitchen knives and knives.

[Problems to be solved by conventional technology and ideas] Conventionally, knife storage cases do not have a knife sharpening section, so when sharpening knives, it is necessary to use a sharpener prepared separately from the knife storage case. figure,
It was very inconvenient.

Structure of the invention [Means for solving the problem] The invention was made to solve this problem, and in the first item, in a cutlery storage case consisting of a case body and its lid, the case body A recess having a substantially V-shaped cross section is formed on the outer surface of the bottom wall of the recess, a whetstone is attached to the recess, and the side edge of the recess is used as a guide for the blade when sharpening the blade. .

The invention described in Section 2 is that in a cutlery storage case consisting of a case body and its lid, a base is provided along one side wall of the case body, and a side wall opposite to the one side wall is provided on this base. Pressing means for partitioning two pairs of cylindrical grindstones each having a different grain size into a recess formed between the two, and for press-welding the outer circumferential surfaces of the partitioned grindstones or for making it possible to release the pressure-welding. Further, a blade insertion opening into which the blade is inserted is recessed in the side wall corresponding to the outer periphery pressure contact portion of both grindstones.

(Function) In the device described in the first claim, a blade with a desired sharpening angle can be easily obtained by placing the blade against the side edge of the recess and letting it guide the blade while sharpening.
Furthermore, if the whetstone is placed in a kitchen or the like when not in use, the whetstone is difficult to see, and since the whetstone does not come into contact with the mounting surface, there is no risk of damage.

Since the device according to the second claim is made up of two sets of grinding wheels with different grain sizes, it is possible to perform rough sharpening and final sharpening, and a sharp blade can be obtained. When the sharpening force decreases, by releasing the pressure contact of the grindstone by the pressure contact means and changing the pressure contact part of the grindstone, the decrease in the sharpening force can be prevented and the entire circumference of the grindstone can be effectively utilized.

[First Embodiment] First, a first embodiment of the present invention will be described with reference to FIGS. 1 to 4.

As shown in FIG. 1, the cutlery storage case 1 consists of a case body 2 and its lid 3, and a recess 5 is formed on the outer surface of the bottom wall 4 at the longitudinal center of the case body 2. The recess 5 extends in the width direction of the case body 2, is open at both side edges, and has a V-shaped cross section. Both slopes 6 within this recess 5,
A grinding wheel 8 is fitted into a mounting portion 6a formed on one slope 6 of the grinding wheel 7, and a center line 9a of a sharpening surface 9 on the grinding wheel 8 is parallel to both side edges 5a and 5b of the recessed portion 5. These side edges 5a and 5b serve as guide portions for guiding the blade 12 during sharpening, as will be described later. Parts of the case body 2 on both sides of the recess 5 serve as gripping parts 10a and 10b when the grindstone 8 is used.

Now, as shown in FIGS. 1 and 2, while supporting the grip 10b of the case body 2 with one hand, place the blade 12 of the knife 11 held in the other hand onto one side edge 5a of the recess 5. Along with guessing, the cutting edge 12 of the blade 12
A is applied to the sharpening surface 9 of the whetstone 8 and the blade 12 is moved back and forth along one side edge 5a of the recess 5, so that the cutting edge 12a of the blade 12 can be sharpened by the whetstone 8. In this case, the sharpening angle can be changed by changing the contact position of the cutting edge 12a with respect to the sharpening surface 9 of the grindstone 8, and the sharpening angle is set at the side edge 5.
Since the polishing is performed while being guided by a and 5b, the polishing is always uniform.

By changing the direction of the case body 2 with respect to the user, the cutting edge 12 can be adjusted for both right-handed and left-handed users.
Both sides of a can be easily sharpened.

In particular, in this embodiment, since the whetstone 8 is attached to the outer surface of the cutlery storage case 1, when sharpening the cutting edge 12a, there is no need to prepare a cutter sharpener separately from the cutlery storage case 1. It can also be used as a sharpener, which is very convenient.

Moreover, the whetstone 8 is attached to the outer surface of the bottom wall 4 of the case body 2.
Since the case body 2 is attached when the whetstone 8 is not in use,
When placed in a kitchen or the like, the bottom wall 4 is naturally on the lower side, so the whetstone 8 is hardly visible from the outside and looks good.

In this case, since the whetstone 8 is installed in the groove 5 of the bottom wall 4 of the case body 2, the whetstone 8 does not hit the mounting surface and does not interfere with the mounting of the case body 2. 8 will not be damaged by hitting the mounting surface or the like.

In addition, since a recess 5 is formed in the center of the case body 1 in the longitudinal direction, and parts of the case body 2 on both sides of this recess 5 are used as gripping parts 10a and 10b, it is easy to support the gripping parts 10a and 10b with one hand. In this state, the user can grip the knife 11 with the other hand and sharpen the cutting edge 12a, making the case body 2 stable and extremely easy to sharpen.

As shown in FIG. 4, when the knife 11 is stored in the case body 2, the blade 12 is supported by the protrusion formed by the recess 5 in the case body 2, so that the blade 12 can be stored stably. I can do it.

[Second Embodiment] Next, a second embodiment shown in FIGS. 5 to 8 will be described.

In this second embodiment, the mounting position of the grindstone 8 is changed from the first embodiment, and in the case shown in FIGS. 5 and 6, the grindstone 8 is attached to the recess 5.
A sharpening surface 9 of the whetstone 8 is disposed in the center between both side edges 5a and 5b of the recess 5 and is parallel to both side edges 5a and 5b of the recess 5.
center line 9a and one side edge 5 of the recess 5 opposite thereto.
The angle θ1 made by the plane connecting a with the sharpening surface 9,
The concentric line 9a and the other side edge 5 of the recessed portion 5 opposite thereto
The angle θ2 that the plane connecting b and the sharpening surface 9 makes is the same.

Therefore, by applying the blade 12 to either side edges 5a, 5b of the recess 5 while keeping the case body 2 in a fixed position, it is possible to use the blade 12 for both right-handed and left-handed people without changing the orientation of the case body 2. However, both sides of the cutting edge 12a can be easily sharpened.

In the cases shown in FIGS. 7 and 8, both the angles θ1 and θ2 are different from each other.

Therefore, the sharpening angle of the cutting edge 12a can be changed between when the blade 12 is applied to one side edge 5a of the recess 5 and when the blade 12 is applied to the other side edge 5b of the recess 5.

[Third Example] Next, a third example shown in FIGS. 9 to 12 will be described.

As shown in FIG. 9, the cutlery storage case 1 of the third embodiment also consists of a case body 2 and its lid 3, and a base portion 13 is provided along a part of one side wall 2a within the case body 2. A knife sharpening part 14 is provided on this base part 13, and a case body 2 is provided opposite to this knife sharpening part 14.
An open portion 15 is formed in the other side wall 2b.
The knife sharpening section 14 will be explained in detail below.

As shown in FIGS. 10 to 12, a recess 17 is formed on this base 13 between one side wall 2a of the case body 2 and the wall 16 on the opposite side.
A partition member 18 as a pressure contact means is inserted into the center of the recess 17 to partition the inside of the recess 17.
Grooves 17a and 17b are formed on both sides. A blade insertion opening 19, which is opened at one side wall 2a and wall portion 16 of the case body 2, is recessed in both grooves 17a and 17b. Both legs 20 protruding from the lower side of the partition member 18 are inserted into the lower surface side of the case body 2, and are movable in the vertical direction and in the direction along one side wall 2a of the case body 2. Therefore, the partition member 18 can also move within the recess 17 within that range. The partition member 18 is fixed from the bottom side of the case body 2 with a set screw 21. Grooves 17a are provided on both sides of this partition member 18,
A slope 18a facing 17b is formed.

The grindstone 8 has a cylindrical shape with a circular cross section, and its diameter and length in the axial direction are the same. This whetstone 8
A pair of fine-grained ones and a coarse-grained one are prepared, and each pair is fitted into both grooves 17a and 17b, and their outer peripheral surfaces 8a are placed on the inner bottom surfaces of both grooves 17a and 17b. At the same time, their end surfaces 8b are connected to the case body 2.
It is supported between one side wall 2a and the wall portion 16 and is rotatably installed. In this side-by-side state, the axes P of both grindstones 8 in both grooves 17a and 17b are parallel to each other within the same plane.

When the setscrew 21 is tightened, both slopes 18a of the partition member 18 are pressed against the outer peripheral surface 8a of one of the two grindstones 8 in the grooves 17a and 17b above its axis P. At the same time, the other whetstone 8 is pushed by the one whetstone 8 and comes into contact with the inside of the recess 17, and both the whetstones 8 are pressed between this and the partition member 18.
are sandwiched and their outer peripheral surfaces 8a are pressed against each other.

Now, when the blade 12 is inserted into one of the blade insertion openings 19 in both grooves 17a and 17b, the blade 1
The second cutting edge 12a is inserted between the outer circumferential surfaces 8a of both grindstones 8 and applied onto the pressure contact portion 22 thereof. When the blade 12 is reciprocated in the direction of the axis P of both grindstones 8, the cutting edge 12a can be sharpened in a state in which it is in contact with the entire outer peripheral surface 8a of the grindstone 8 in the direction of the axis P. In addition, if the sharpening power decreases due to iron powder adhering to both grindstones 8, the setscrew 2
1 to release the pressure contact by the partition member 18, and then rotate both the grindstones 8 little by little, and then position both the grindstones 8 by the pressure contact by the partition member 18 in the same way as in the case described above. The cutting edge 12a can be sharpened at another portion of the outer peripheral surface 8a.

In this way, the entire outer circumferential surface 8a of both grindstones 8 can be effectively utilized, which is very economical and does not reduce the sharpening power.

Furthermore, since both grindstones 8 have the same length in the direction of the axis P and their end surfaces 8b coincide with each other, it is possible to sharpen uniformly from the tip of the cutting edge 12b to the entire base end of the handle side.

In particular, in this third embodiment, since the whetstone consists of two sets, one with coarse grains and one with fine grains, a sharp blade can be obtained by rough sharpening and finish sharpening, and the entire circumference of the whetstone can be effectively utilized. Because it is possible, there is no reduction in sharpening power. Furthermore, since the whetstone 8 is installed inside the knife storage case 1, when sharpening the cutting edge 12a, there is no need to prepare a knife sharpener separately from the knife storage case 1, and the knife storage case 1 can also be used as a knife sharpener. It is very convenient.

Furthermore, by covering the case body 2 with the lid 3 when the whetstone 8 is not in use, the whetstone 8 can be covered up and the appearance will be improved.

Effects of the invention According to the invention described in the first claim, when sharpening the blade, the desired sharpening angle can be easily obtained by placing the blade against the side edge of the recess and letting it guide the blade. Furthermore, when the whetstone is placed in the kitchen when not in use, it is difficult to see and the whetstone does not come into contact with the mounting surface, so there is no risk of damage.

The invention described in the second claim consists of two sets of grindstones with different grain sizes, so rough sharpening and final sharpening are possible, and a sharp blade can be obtained.
If the grinding force decreases due to iron powder etc. adhering to the whetstone, by releasing the pressure contact of the whetstone using the pressure welding means and changing the pressure contact part of the whetstone, it is possible to prevent the decrease in sharpening power and also to completely reduce the sharpness of the whetstone. This has the effect that the surrounding area can be used effectively.
