Abstract

PROBLEM TO BE SOLVED: To easily cope with the abrasion of a blade face of a knife without delay, by cutting a number of almost parallel slots at desired intervals along a surface of a hard plate. SOLUTION: A face bar on a surface of which a number of almost parallel slots 5 are cut at random, is bent into the U-shape, and is molded and machined to a work bench 1. When a knife is ground, the work bench 1 is taken out to be fit to one of left and right side edge parts of a chopping board 2, and tightly fixed by bonding a Hook and Loop fastener face. A suitable amount of the fluidized abrasive is extruded from a tube onto an upper face of the work bench 1, and roughly spread by a finger. Further the abrasive is flattened by a cutter from an upper part, to bury the abrasives into the slots 5. Then the blade face is moved foward and backward along the slots 5 of the upper face 4 to be ground. On this occasion, the water is unnecessary, so that the sharpening can be performed in safety with a comfortable position at any stable, wide and bright place having the height suitable for the work, such as on the table or the like.

Description of the Related Art In general, a polishing process is roughly classified into a process in which fine abrasive grains are used as a tool in a state where they are kept as they are or in a state where they are fixed to a grindstone piece. Any of these methods is used for the sharpening of the knife, except for the method of using a whetstone as a tool, because it requires power and is not familiar to the household of ordinary people, so it is necessary to sharpen the knife and sharpen it. If
A square whetstone in which abrasive grains are hardened with an adhesive has been used. On the other hand, the present invention uses abrasive grains as they are, and has some points in common with the conventional lapping method. On the other hand, in this method, using a fluid abrasive in which abrasive grains are mixed in a gel, the method is performed by a manual operation similar to polishing a blade with a grindstone on a special work surface. They are completely different.

の煩わしさのために、とかく敬遠され勝ちであった。The grindstone which has been used in the past has an excellent function in terms of polishing a knife, but it is hard and heavy because it is a block of square stone. Is extremely difficult to handle. In addition, since they are not used very often, they are usually placed in one corner of a tool box or in the back of a storeroom. It can cause injuries to your feet and damage to the floor by slipping and falling. The kitchen knife, which is the most frequently used knife, is usually used by women at home, except for professional cooks. Despite being strong in the middle, this annoyance led him to be shunned and won.

It is necessary to work in a posture, which puts an excessive burden on the worker, and it is hard to say that the polishing effect gives a good result. Also, it is by no means preferred that the work table is a square whetstone block. Therefore,
In addition to the hassle of preparation, the impression that it is not very pleasant work, while pressing the necessity of polishing, I will continue to use a sharply cut kitchen knife with patience and improve the efficiency of cooking Not only will it lower it, but it will hinder the pleasure of cooking.

It is housed in a tube. This is extruded onto a surface material of an appropriate size, spread lightly with a finger, and then the surface of the blade to be polished is pressed from above and slid back and forth to reciprocate to grind the blade surface. At that time, as a face material used for the work, a hard material such as metal, glass, and ceramics is preferable because there are few scratches remaining after the work, and among them, metals, particularly stainless steel are preferable materials for the following reasons. It is. What is particularly important here is that when the blade is polished using a fluid abrasive, the work surface is flat and smooth, and a large number of narrow grooves are provided along the reciprocating movement direction of the blade. Is to provide a good polishing effect. This narrow groove has a width of about 0.3 to 1.2 mm and a depth of 0.2 to
About 1.0 mm, almost parallel to each other, 0.3 to 1.2 mm
The groove width, the groove depth, and the interval may be all the same, but are not particularly required, and are provided at random.

着性及び弾性効果によるものと推定される。[0008] The result of obtaining a good polishing effect by polishing using a face material having a large number of such narrow grooves formed in parallel is obtained empirically, and the reason is not clear. If the surface is flat, the flowable abrasive on the surface is
If the blade is pressed firmly to reinforce the polishing effect, the polishing material can hardly stop on the surface and the polishing effect cannot be obtained. If the force for pressing the blade surface is weakened, the abrasive can remain on the surface, but the frictional force with the blade surface is weakened and the polishing effect does not increase. However, if many narrow grooves are provided as in the present invention, the abrasive material displaced by rubbing with the blade surface is
It enters the groove and stops there and exerts an appropriate polishing effect on the blade surface moving along the narrow groove by the polishing surface having the same height as the working surface formed by the abrasive grains contained in the jelly-like body. It is presumed that. Further, with the movement of the blade surface, the abrasive material in the groove is drawn out of the groove, moves on the work surface, is strongly pressed against the blade surface, and has an effect of contributing to the effect of enhancing the polishing action. This is presumed to be due to the tackiness and elasticity of the gel-like material mixed with the abrasive grains.

ってはならない。The reason for providing only a narrow groove substantially parallel to the working surface as described above is that the work of sharpening the blade is performed by reciprocating the worker in the front-rear direction while holding the blade surface so as to coincide with the polishing surface. In order to smoothly perform this movement even if the user is unfamiliar with the work, there must be no irregularities that cause the blade to be caught in the direction of the movement of the blade. This is a result of satisfying the two conditions that a concave portion capable of holding the material is required, and the groove must not have another shape.

ましくは３０度以下にすべきである。Here, in order to obtain a uniform polishing effect without polishing unevenness, the blade must be moved substantially parallel to or slightly oblique to the direction of the narrow groove. By moving the blade slightly obliquely to the narrow groove on the surface, the blade surface uniformly contacts the abrasive material staying in the groove over a wide area,
It is evenly pressed against the abrasive pulled out on the work surface, and has an effect of providing a uniform polishing action. The abrasive on the work surface exerts a sharp abrasive action on the blade surface, but its action time is extremely short, and it is pushed back into the groove,
The polishing effect as a whole is extremely mild, and even a woman who is unfamiliar with the polishing operation can easily carry out the polishing and obtain an excellent polishing effect. Here, the slightly oblique angle with respect to the work surface refers to 40 degrees or less, and more preferably 30 degrees or less.

は避けがたく、適性に劣ると言わざるを得ない。As described above, stainless steel is preferable as a work surface. However, since stainless steel is a hard material, it is hardly damaged by friction with an abrasive, and a cutting process for providing the above-mentioned narrow groove on the surface. To be attached to the edge of the cutting board, so that it can be easily polished at any time, as described later.
This is because it has ductility suitable for molding. From the viewpoint of rust generation, glass and ceramics are also suitable,
It is quite difficult to form a groove on the surface or form a shape to be attached to a cutting board, and it is not a preferable material.
From these points, although aluminum is appropriate, it is inferior to stainless steel in terms of durability due to surface hardness. Also, it is unavoidable that the alumite treatment of the aluminum surface or the chromium plating treatment of the steel is inferior to the surface damage due to the abrasive and is inferior in suitability.

を設ける方が好ましい。The narrow grooves on the polishing surface material are formed by arranging a large number of elongated recesses at intervals similar to the groove width and substantially parallel to each other. Since it cannot be held in the groove, the function as a polishing work surface cannot be maintained. Conversely, if it is too wide, the tip of the blade surface may enter and be damaged, which is not preferable. Also, although the depth of the groove increases the amount of abrasive material retained in the groove, it is only part of the surface that contributes to the polishing action, and the remaining amount is discarded after polishing and is wasted. , Need to be of appropriate depth. Therefore, the width of the groove is about 0.3 to 1.2 mm and the depth is 0.2 to 1.0 mm
Degree is appropriate, furthermore, about 0.5 to 1.0 mm width and depth
A suitable range is about 0.3 to 0.6 mm. Similarly, if the gap between the grooves is narrow, the abrasive material can hardly stay on the surface, and a strong contact effect with the blade surface is not obtained, so that a long polishing time is required, and conversely, If the width is too wide, the area of the groove portion is relatively reduced, and the polishing effect is reduced. Therefore, the width is preferably about 0.3 to 1.2 mm, and more preferably about 0.5 to 1.0 mm, which is the same as the width of the groove. It is preferable to provide a slightly curved portion by dropping.

It is an epoch-making product that changes by 80 degrees, and it is clear that frequent polishing work will be performed in each household in the future.

く、以下に詳細に説明する。[0014] For this purpose, most basically, a surface material for polishing work having a hard surface is bent into a U-shape according to the thickness of the cutting board, and the cutting board is sandwiched from above and below. Deformed into a worktable with a shape to be attached to the part. At this time, the work table should be formed so that the direction of the narrow groove of the face material matches the width direction of the cutting board or is slightly inclined.
In normal polishing work, it is natural for the operator to reciprocate the blade in the front and back direction of the body, and not exactly exactly the reciprocating parallel movement at the same position of the blade is repeated. This naturally coincides with the slightly inclined preferred moving direction of the blade in the present invention. However, by machining the worktable so that the direction of the narrow groove on the work surface is fixed at a slight inclination in advance, even if the reciprocating movement in a completely parallel manner is strictly repeated, the blade is preferably used. The direction of movement will still coincide with the preferred polishing direction without any consideration. The workbench in which the work surface material is bent into a U-shape can be said to have the effect of fixing to the cutting board by the pressing force by the upper and lower surfaces, but because it is not enough, there is a possibility that it will shift in the front and rear direction during polishing, In particular, when the cutting board is made of plastic, it tends to be more slippery than when it is made of wood. Therefore, in such a case, it is better to have an auxiliary function of fixing the face material to the edge of the cutting board by any appropriate means. For example, a plastic joining member known by the trade name Velcro may be formed in a U-shape. Paste it on the inside of the back of the cutting board and the corresponding part of the side of the cutting board, drill a small hole in the back of the face material with a drill etc. and fix it to the side of the cutting board by penetrating a small screw. Is also good. When the fixing of the face material is assisted by using Velcro, there is no shift during polishing, and it is easy to remove after the work, which is convenient. On the other hand, the fixing effect when a screw is used is extremely strong, but it is inconvenient for attaching and detaching the face material. Therefore, it is suitable for a case in which the polishing is frequently performed while the fixing is always performed. It goes without saying that the deformed shape of the face material may take various other shapes, as will be described in detail below.

FIG. 1 shows an example in which a face material in which a large number of narrow grooves substantially parallel to the surface are randomly provided is bent into a U-shape to form a working table 1. On the surface of a stainless steel plate with a thickness of 0.5 mm, a groove with a width of about 0.7 mm and a depth of about 0.3 mm
After cutting approximately parallel at intervals of about 0.8 mm, the shoulders of the remaining ridges are lightly polished and smoothed to create a work surface on which a number of narrow grooves 5 are formed. Next, according to the thickness of the cutting board 2 to be applied, the face material is bent into a U-shape along the groove direction. The size of the upper surface 4 is approximately 7 cm wide, 20 cm high,
The width of the back surface 7 is about 12 mm, and in this embodiment, the lower surface 6 is almost the same size as the upper surface. However, it is not usually necessary, and the size of the lower surface may be any size as long as it can appropriately hold the cutting board. A small piece of one side of the brand name Velcro is adhered to both ends on the inner side of the back surface, and a small piece of the opposite side of the Velcro is adhered to a position corresponding to the side surface 8 of the cutting board 2. When sharpening the kitchen knife, take out the worktable 1 and insert it into the left or right side end of the cutting board, join the Velcro surface and fix it firmly, and apply an appropriate amount of fluid abrasive to the upper surface 4 from the tube. Extrude and spread lightly with your finger, level with a knife and fill the groove with abrasive material,
Subsequently, the blade surface is polished by moving back and forth along the narrow groove 5 on the upper surface 4. In that case, unlike a conventional whetstone, it does not need water, so there is no need to work near a tap on the tap, and it is close, stable, wide, bright, and any height suitable for work, such as on a table In this place, she was able to work safely and in a comfortable posture, and even a woman with little experience was able to carry out the polishing work comfortably and also obtained an excellent sharpening effect.
