  Embodiments of the present invention will be described below with reference to the drawings.

<First embodiment>
Fig.1 (a) is a perspective view of the sharpener 11 which concerns on 1st embodiment of this invention. FIG.1 (b) is a perspective view which shows the usage example of the sharpener 11 which concerns on 1st embodiment of this invention.

  As shown in FIG. 1A, the sharpener 11 has a sharpening tool 21 for sharpening a cutting edge 401 of a blade 4 and a sharpening base 31 for placing a blade 41.

  First, the sharpening tool 21 will be described. The sharpening tool 21 is a member having a plate shape on one end side and a rod shape on the other end side, and a polishing member 201 is provided on one surface of the plate shape. The polishing member 201 is a member that the user presses against the blade edge 401 of the blade 41 to perform polishing. Here, it is assumed that the polishing member 201 is a rectangular plate-shaped grindstone in which a large number of abrasive grains are bonded with a binder. Such a polishing member 201 can be formed by embedding a plate-like grindstone in the sharpening tool 21.

  Further, the grindstone may be configured to be detachable so that the polishing member can be replaced. As an example, FIG. 2 shows a perspective view of a sharpening tool 21a which is a modification of the present invention. As shown in the figure, the sharpening tool 21a is provided with a magnet plate 204 on one plate-like surface, and one surface of the polishing member 201 is made of a magnetic material. It can be bonded and fixed. Accordingly, for example, the polishing member 201 can be replaced with a coarse grindstone (for example, a particle size of 500 #), a fine grindstone (a particle size of 800 #), a polished grindstone (a particle size of 1000 # or more), etc., and desired polishing can be performed.

  Furthermore, the installation part of the grindstone may be configured to be detachable so that it can be replaced. For example, a tip end joint portion (convex shape) is provided around the middle of the sharpening tool so that the tip end portion having a concave hole can be inserted and removed. By fixing the grindstone to the tip, the grindstone can be freely replaced.

  The polishing member used for the polishing member 201 is not limited to the artificial grindstone as described above, and any member may be used. Examples thereof include a grindstone cut out from natural stone and abrasive cloth paper such as sandpaper. Further, the abrasive grains may be any material regardless of the grain size, bonding degree, and subdivision. For example, diamond, silicon carbide, zirconia, alumina, etc., or a mixture thereof. Of course, the type of binder, such as rubber or resin, is not limited.

  Returning to FIG. 1, a grip portion 203 is formed on the other end of the sharpening tool 21 in the bar shape. Here, the gripping portion 203 has irregularities, a constriction, and the like, and has a shape that is familiar to the user's hand.

  A guide 202 is formed between the polishing member 201 and the grip portion 203. The guide 202 has a part of a plate-like surface protruding in a bar shape.

  A roller 205 is provided at the tip of the guide 202. Both ends of the roller 205 are clamped and fixed to the guide 202, and the rotation direction is restricted. The user performs polishing by the polishing member 201 by rolling such a roller 205 in contact with a predetermined surface. At that time, the moving direction of the guide 202 by the rotation of the roller 205 is regulated in a straight line, so that stable polishing can be performed.

  Further, the rotation direction of the roller 205 may be variable. For example, as shown in FIGS. 2A and 2B, the direction of the roller 205 can be freely rotated and fixed 360 degrees by allowing the tip of the guide 202 to rotate together with the roller 205. The sharpening tool 21a described in FIGS. 2A and 2B has a structure in which the tip portion of the guide 205 is rotated by being pulled down and fixed by being pushed up. According to such a configuration, it is possible to cope with various polishing directions by arbitrarily changing the rotation direction of the roller 205.

  The height, size, and inclination of the guide are designed based on the type and application of the blade 4 and the curve of the blade edge 401. When the guide 202 is held perpendicular to a predetermined plane, the polishing member 201 is designed. It is desirable to have a predetermined inclination with respect to the mounting table 301 described later. Details will be described later.

  Next, the sharpening table 31 will be described. The sharpening table 31 has a mounting table 301 for mounting the blade 41, a suction member 302, a step part 303 forming a step with the mounting table 301, and a non-slip 304.

  The mounting table 301 is a member that forms a surface for mounting the blade 41 of the blade 4. The surface of the mounting table 301 is inclined with respect to the horizontal plane so that the stepped portion 303 side (the blade edge 401 side when the blade 4 is mounted) is lowered. Since the cutting edge 401 is lower than the peak 404, the risk of sharpening work is avoided and the sharpening water is easy to turn around the cutting edge, and the sharpening effect is high as compared with the case where the cutting edge is installed with the cutting edge facing upward. The inclination angle is not particularly limited, and varies depending on the type of the blade 4 to be polished, the curve of the blade edge 401, the application, and the like.

  Further, the blade 4 can be prevented from slipping by providing an adhesive on the surface of the mounting table 301 or by molding the mounting table 301 itself with a rubber material. Hereinafter, the long side direction of the mounting table 301 is referred to as a long side direction, and the short side direction is referred to as a short side direction.

  The adsorption member 302 is a member for adsorbing and fixing the blade 41 to the mounting table 301. A material that can fix the metal blade 41 by a magnetic force, such as a neodymium magnet, can be used for the attracting member 302. Further, a sheet member having a large frictional force such as rubber or silicon, or a flexible sheet-like magnetic body may be attached to the mounting table 301. As described above, the sheet member having a large frictional force is attracted in the vertical direction by the magnet, and the sliding of the blade 41 can be suppressed and firmly fixed to the mounting table 301.

  The step portion 303 is a portion that forms a step with respect to the mounting table 301. The space formed by such a step prevents the polishing member 201 from coming into contact with the sharpening table 31 when the user performs polishing.

  The fixing members 304 are anti-slip members that are provided at the four corners of the substantially rectangular bottom surface of the sharpening table 31 and suppress the movement of the sharpening table 31. For such a fixing member 304, a material having a large frictional force such as rubber or resin can be used.

  The knife 4 is a knife mainly composed of a blade 41 and a handle 42 (there is no limitation on the classification of a single knife and a double knife, and the classification of a knife such as a Japanese knife, a Western knife, a Chinese knife, etc.). However, the present invention is not limited to this, and other blades such as knives, scissors, scissors and scissors may be used. In the following, the blade 41 is referred to as a blade edge 401 where the blade is formed, a jaw 402 as an end point on the handle 42 side of the blade edge 401, a tip 403 at the tip of the blade edge 401, and an edge portion opposite to the blade edge 401 as a peak 404. And

  Hereinafter, how to sharpen the blade using the sharpener 11 will be described. FIG. 3 is an explanatory diagram for explaining the sharpening operation when the sharpener 11 according to the first embodiment of the present invention is used. FIG. 4 is a perspective view of the sharpening tool 21 according to the first embodiment of the present invention.

The sharpener 11 is used in the following usage procedure, for example.
(1) First, the blade 41 of the blade 4 is placed on the placing table 301 so that the blade edge 401 protrudes onto the stepped portion 303. At this time, the blade 41 is fixed by the adsorption member 302 on the mounting table 301 having a predetermined inclination.
(2) Next, the user holds the grip portion 203 of the sharpening tool 21. Then, the polishing member 201 is positioned so as to touch the blade edge 401 while supporting the sharpening tool 21 by bringing the roller 205 into contact with a predetermined plane (here, the same plane as the plane on which the sharpener 11 is placed). Note that when the guide 202 is erected substantially perpendicular to the plane, the polishing member 201 comes into contact with the blade edge 401 so as to form a predetermined angle.
(3) The user rolls the roller 205 of the guide 202 on a plane, and moves the polishing member 201 in the rotation direction of the roller 205 (here, the short direction). Thereby, the polishing member 201 slides on the blade edge 401 and the blade edge 401 can be polished.

  In FIG. 3, the example at the time of grinding | polishing by the reciprocating motion of the sharpening tool 21 is shown. When a force to move the roller 205 as the movement fulcrum from the peak 404 side to the blade edge 401 side is applied to the gripping part 203 as the force point, the contact angle and the contact position of the polishing member 201 as the action point to the blade 41 are continuous. Changes. That is, as the roller 205 moves, the inclination of the guide 202 with respect to the plane increases. Thereby, the angle (polishing angle A) formed by the blade center line and the polishing surface (tangent line of the polishing member 201 with respect to the blade tip 401) A is also directed toward the angle (polishing angle B) formed by the blade center line and the polishing surface B. Become bigger. Further, the contact position (action point) of the cutting edge 401 with the polishing member 201 also moves from the peak 404 side to the cutting edge 401 side as shown in FIG.

  Conversely, when a force for moving the roller 205 from the blade edge 401 side to the peak 404 side is applied to the gripping portion 203 as a power point, the inclination of the guide 202 with respect to the plane decreases as the position of the roller 205 moves. In addition, the angle formed by the blade center line and the polishing surface B (polishing angle B) also decreases toward the angle formed by the blade center line and the polishing surface A (polishing angle A). Further, the contact position (action point) of the blade edge 401 with the polishing member 201 also moves from the blade edge 401 side to the peak 404 side as shown in FIG.

  The continuous change in the contact angle and contact position of the polishing member 201 to the blade 41 is particularly a blade having a curved cross section (in Japan, a blade tip having a curved surface like a shell of a bivalve shell is called a clam shape. Effective). In such a cutter, if the curved surface formed on the cutting edge can be shaved or stepped, the sharpness may be lost and the life may be shortened or the characteristics may be lost. Therefore, if the sharpening device 11 according to the present invention is used for sharpening as described above, the polishing angle increases toward the cutting edge 401 side and decreases toward the peak 404 side. Therefore, polishing can be performed without impairing the curved surface.

  Further, as shown in FIG. 2, it is also possible to perform another sharpening operation by changing the moving direction of the roller 205. For example, by changing the moving direction of the roller 205 by 90 ° and moving the polishing member 201 in the longitudinal direction of the blade 41 (from the cutting edge 403 side to the jaw 402 side), a sharpening operation that is substantially parallel to the cutting edge 401 is also possible. It becomes.

  Further, by using the grindstone having a different particle size by replacing the polishing member 201, first, the grindstone with a coarse particle size may be sharpened, and the final sharpening may be performed with the grindstone with a fine particle size.

  Specifically, first, a grindstone having a coarse particle size is used to sharpen the blade 41 in the longitudinal direction. Next, finishing sharpening is performed in the short direction using a fine grindstone. When sharpening is performed in this way, the sharpening on the cutting edge 401 in the longitudinal direction becomes a fine sharpening (line scratch) on the cutting edge 401 from the peak 404 side to the cutting edge 401 side. By entering such a line flaw, the sharpness of the blade 4 can be improved or the sharpness can be prolonged.

  As described above, according to the sharpening device according to the present invention, when the guide 202 is moved, the contact angle between the polishing member 201 and the blade 41 continuously changes. Therefore, the polishing along the curved surface is performed as described above. realizable.

<Second Embodiment>
Next, a sharpener 12 according to a second embodiment of the present invention will be described. FIG. 5 is a perspective view of the sharpener 12 according to the second embodiment of the present invention. FIG. 6 is an explanatory diagram for explaining the sharpening operation when the sharpener 12 according to the second embodiment of the present invention is used. In the following embodiments, the same parts as those in the previous embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  The sharpening device 12 according to the present embodiment has substantially the same configuration as the sharpening device 11 according to the first embodiment, but is sharpened in that the stepped portion 303 has a sharpening base 32 that forms a flange portion 305. Different from the vessel 11. The flange portion 305 of the sharpening table 32 is provided with a wall surface on the side surface on the outer periphery of the stepped portion 303, and can store the polishing water 306 therein. Note that the collar portion 305 may be coated so that slimming does not occur.

  Such a sharpening table 32 can be polished by the sharpening tool 21 while the cutting edge 401 of the blade 4 is immersed in the sharpening water 306. Therefore, it is not necessary to supply water to the cutting edge 401 or the polishing member 201 during polishing. Further, the surface of the mounting table 301 is inclined with respect to the horizontal plane so that the stepped portion 303 side (the blade edge 401 side when the blade 4 is mounted) is lowered. When the blade edge 401 is lower than the peak, the wall surface of the flange 305 surrounds the blade edge 401, and the safety during the sharpening operation is increased. In addition, the sharpening water is easy to turn around the cutting edge and the sharpening effect is enhanced.

  The sharpening water 306 of the collar 305 does not have to immerse the cutting edge 401. For example, as shown in FIG. 6, water that does not immerse the cutting edge 401 may be stored so that only the polishing member 201 is immersed in water when the sharpening tool 21 is moved. Further, the user may supply water by appropriately immersing the polishing member 201.

  Thus, according to the sharpening device 12 according to the second embodiment of the present invention, it is possible to save the trouble of water supply to the blade and the grindstone and to prevent the sharpening water from being scattered around the sharpening device when polishing.

<Third embodiment>
Next, a sharpening device 13 according to a third embodiment of the present invention will be described. FIG. 7 is a perspective view of the sharpener 13 according to the third embodiment of the present invention. FIG. 8 is an explanatory diagram for explaining the sharpening operation when the sharpener 13 according to the third embodiment of the present invention is used.

  The sharpener 13 according to this embodiment has substantially the same configuration as that of the sharpener 12 according to the second embodiment, but has a sharpening stand 33 in which a guideway 307 is formed next to the mounting table 301. It differs from the sharpener 12 in that respect.

  The guideway 307 is a substantially rectangular groove that is formed on the opposite side of the collar portion 305 across the mounting table 301 and restricts the movement of the guide 202. When the roller 205 is rolled on the bottom surface of the guideway 307, the roller 205 is locked on the side surface of the guideway 307.

  The shape and inclination angle of the guideway 307 are not limited, and the guideway 307 is designed based on the type and application of the blade 4 and the curve of the blade edge 401. For example, the side surface in the longitudinal direction is preferably configured to follow the curve of the blade edge 401. That is, it is preferable that the blade edge 401 and the guideway 307 are formed substantially in parallel. Further, the groove width in the short direction of the guideway 307 is larger than that of the roller 205 so that the roller 205 can reciprocate in the short direction.

  In FIG. 8, the example at the time of grinding | polishing using the sharpener 13 is shown. The user places the polishing member 201 in contact with the blade edge 401 while supporting the sharpening tool 21 by bringing the roller 205 of the guide 202 into contact with the bottom surface of the guideway 307. Then, the roller 205 is rolled in the guideway 307, and the guide 202 is moved in the rotation direction of the roller 205. At this time, the movement range of the guide 202 is limited by the guideway 307.

  As described above, the movement of the guide 202 is restricted by the guide way 307, so that an unnecessary surface of the blade is not polished and polishing suitable for the blade can be performed. Therefore, even an amateur can achieve sharpening with good finish simply and accurately.

<Fourth embodiment>
Next, a sharpening device 14 according to a fourth embodiment of the present invention will be described. FIG. 9 is a perspective view of a sharpener 14 according to a fourth embodiment of the present invention. FIG. 10 is an explanatory diagram for explaining the sharpening operation when the sharpener 14 according to the fourth embodiment of the present invention is used.

  The sharpening device 14 according to this embodiment has substantially the same configuration as the sharpening device 12 according to the second embodiment, but the sharpening tool 24 in which the curved surface 206 and the stopper 207 are formed, and a guide next to the mounting table 301. It differs from the sharpener 12 in that it has a sharpening table 34 on which a bar 308 is formed.

  The sharpening tool 24 has a curved surface 206 instead of the guide 202 between the polishing member 201 and the grip portion 203. The curved surface 206 is formed by bending a plate-shaped surface in the direction of the polishing member 201. Such a curved surface 206 is provided as a guide contact portion for contacting a guide bar 308 described later. Further, stoppers 207 protruding in a convex shape are provided at both ends of the curved surface 206. Hereinafter, when distinguishing both, the stopper formed in the grinding | polishing member 201 side is called stopper 207A, and the stopper formed in the holding part 203 side is called stopper 207B.

  In FIG. 9, the sharpening tool 24 is configured to include the polishing member 201, the curved surface 206, and the stopper 207 on both sides, but may be configured to include these only on one side.

  The sharpening stand 34 has a guide bar 308 that serves as a moving fulcrum of the sharpening tool 24. The guide bar 308 is a cylindrical roller member provided at a position higher than the mounting table 301 of the polishing table 34 and substantially parallel to the mounting table 301 in the longitudinal direction, and both ends thereof are rotatably supported by the polishing table 34. Has been. Thus, it is desirable that the guide bar 308 extends in a direction along the blade edge 401 of the blade. The guide bar 308 is formed of a material having a high frictional force so that the guide bar 308 can be rotated by sliding the curved surface 206 in the short direction. Thereby, it can also prevent that the sharpening tool 24 slips to a longitudinal direction.

  Such a sharpener 14 is used by sliding a curved surface 206 formed between both stoppers of the sharpening tool 24 on the guide bar 308 in the short direction. At this time, the stopper 207 comes into contact with the guide bar 308 and stops its movement.

  In FIG. 10, the example at the time of grinding | polishing using such a sharpener 14 is shown. In FIG. 10, only the curved surface 206 formed on one surface is shown for convenience.

  First, the curved surface 206 is brought into contact with the guide bar 308 and the polishing member 201 is positioned so as to touch the blade edge 401. In this state, when a force for moving the curved surface 206 from the peak 404 side to the blade edge 401 side is applied to the gripping portion 203 as a power point, the curved surface 206 slides and the guide bar 308 as a movement fulcrum rotates. And while the inclination of the sharpening tool 24 changes, the contact angle and contact position to the blade 41 of the grinding | polishing member 201 which is an action point also change continuously.

  Specifically, when the curved surface 206 is moved from the position where the stopper 207A is in contact with the guide bar 308 to the position where the stopper 207B is in contact, the angle between the blade center line and the polishing surface A (polishing angle A) is the blade center line. Increases toward the angle formed by the polishing surface B (polishing angle B). Further, the contact position (action point) of the blade edge 401 with the polishing member 201 also moves from the peak 404 side to the blade edge 401 side.

  Conversely, when a force to move the curved surface 206 in the short direction (from the blade edge 401 side to the peak 404 side) is applied to the gripping portion 203 as a power point, the inclination of the sharpening tool 24 changes, and the blade centerline and the polishing surface The angle formed by B (polishing angle B) decreases toward the angle formed by the blade center line and the polishing surface A (polishing angle A). Further, the contact position (action point) of the blade edge 401 with the polishing member 201 also moves from the blade edge 401 side to the peak 404 side.

  As described above, the contact angle and the contact position of the polishing member 201 to the blade 41 continuously change according to the curved blade, so that it is possible to perform suitable polishing on the curved blade edge. is there.

<Fifth embodiment>
Next, a sharpening device 15 according to a fourth embodiment of the present invention will be described. FIG. 11 is a perspective view of a sharpener 15 according to a fifth embodiment of the present invention.

  The sharpener 15 according to this embodiment has substantially the same configuration as the sharpener 14 according to the fourth embodiment, but has a sharpening tool 25 in which one curved portion 206 is formed as a flat plate as a guide contact portion. It differs from the sharpener 14 in that.

  The flat plate surface 208 is a plane substantially parallel to the polishing member 201, and stoppers 207 are formed at both ends thereof.

  FIG. 12A is an explanatory diagram for explaining a sharpening operation when the curved surface 206 of the sharpening tool 25 according to the fifth embodiment of the present invention is used, and FIG. It is explanatory drawing for demonstrating the sharpening operation | movement at the time of using. Here, a single-edged blade 4a having a curved blade on one side of the blade edge 401 is used as an object to be polished.

  As shown in FIG. 12A, when polishing is performed by bringing the curved surface 206 into contact with the guide bar 308, as described in the fourth embodiment, along with the change in the inclination of the sharpening tool 24, The contact angle and contact position of the polishing member 201 with the blade 41 also change continuously. Therefore, by using the polishing member on the curved surface 206 side, polishing can be performed without impairing the curved surface of the cutting edge on the curved surface side.

  On the other hand, as shown in FIG. 12B, when polishing is performed with the flat plate surface 208 in contact with the guide bar 308, the blade center line and the polishing surface (tangent line of the polishing member 201 to the blade tip 401) C The angle formed by (polishing angle C) does not change. Therefore, by using the polishing member 201 on the flat plate surface 208 side, it is possible to perform linear polishing on the cutting edge on the side formed in a linear shape.

  Thus, according to the sharpener 15 according to the present invention, since it is possible to select whether or not the contact angle of the polishing member 201 to the blade 41 is changed, the cutting edge can be applied to a cutting tool having curved and straight blades. It is possible to realize suitable polishing according to the shape.

  The above-described embodiments of the present invention are intended to illustrate the gist and scope of the present invention and are not intended to be limiting. Many alternatives, modifications, and variations will be apparent to those skilled in the art.

  For example, the curved surfaces 206 having different grain sizes, materials, and curves may be combined.

  The roller 205 may be spherical as long as the movement fulcrum is movable. Furthermore, the guide bar 308 is not necessarily a roller member as long as the curved surface 206 and the flat plate surface 208 are slidable.

  Further, the stopper 207 is not necessarily provided.

  In addition, each said figure shows the main structure of the sharpening tool in describing the characteristic of this invention, and does not exclude the structure required for a general sharpening tool.
