Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a simple grindstone that easily grinds barber scissors used by barbers and hairdressers.

[0002]

[Prior art]

 Conventionally, barber scissors for business use used by barbers or hairdressers are made of robust metal members, but the sharpness deteriorates in a relatively short period of time due to the high frequency of use. However, in the case of a razor, it can be polished relatively easily using a leather whetstone or the like, but in the case of scissors, the angle at which it is polished needs to be accurate. However, it was extremely difficult to sharpen scissors because it required skill and experience.

[0003]

[Problems to be solved by the invention]

 Normally, scissors, whose sharpness has deteriorated due to frequent use in barber shops and beauty salons, etc., are re-sharpened by requesting a specialist in blade sharpening. However, after the grinder collects and resharpens the scissors, it takes a few days for the scissors to be brought back again, during which time barbers cannot use their favorite scissors. For this reason, alternative scissors must be used during that time, but the scissors used by barbers and the like are expensive, and the disadvantage is that the cost is too high in barber shops with multiple barbers. Was. The purpose of the present invention is to allow a barber or the like to sharpen the sharpened scissors by himself in a short time so that the sharpness can be restored and used immediately.

[0004]

[Means for Solving the Problems]

 In the present invention, a small-diameter handle portion is formed at at least one end of a cylindrical body, and a plurality of concave portions are provided at regular intervals on a circumferential surface of the cylindrical body in parallel in a longitudinal direction. A plurality of whetstone pieces each having a different whetstone surface of diamond particles are respectively provided on the surface of the cylinder left. In addition, the tapered reduced diameter portion continuously provided at the end of the cylindrical surface portion of the cylindrical body according to the present invention is disposed obliquely with respect to the end surface of the cylindrical body, and is disposed on the grindstone surface of the grindstone piece. On the other hand, guide slopes having different polishing angles for rough finishing, medium finishing, and finishing are provided close to the grindstone surface.

[0005]

[Embodiment of the invention]

 The embodiment according to the present invention will be described with reference to the drawings. Small-diameter handles 3, 3 are integrally provided at both ends of a substantially cylindrical body 1, and the circumferential surface of the cylindrical body 1 has a constant or arbitrary spacing. It is preferable to provide three or four recesses 5 and 5 in the longitudinal direction, respectively, in order to use the peripheral surface of a columnar body having a suitable thickness as it is, preferably three or four in this embodiment. It is formed. The concave portion 5 has a function of a relief portion for releasing the fingertip of the hand holding the blade so as not to disturb the polishing operation when the blade is polished with a grindstone piece formed on the surface of the cylindrical body. I have. At least one recess is required for one grindstone surface.

The cylindrical surface portions 1 a, 1 b, 1 c left between the recesses 5, 5 are slender and have slightly curved surfaces, respectively, and are formed three in parallel with the recesses. is there. At both end portions of the cylindrical surface portions 1a, 1b, 1c, reduced diameter portions 7, 7 are formed continuously and continuously so as to taper so as to gradually decrease in diameter toward both end portions.

[0007] Grindstone pieces, which will be described later, are bonded and fixed to the respective cylindrical surface portions 1a, 1b, 1c. That is, the grindstone pieces 11a, 11b, and 11c are formed by applying an adhesive to the surface of a flexible member such as paper or cloth and spraying diamond particles on the surface to form a grindstone surface 19 made of diamond particles on the surface. I have.

The first grindstone pieces 11a formed by using diamond grain pieces having different particle diameters are, for example, particles having a grain size of 300 for rough finishing, and the second grindstone pieces 11b are, for example, 600 grains for medium finishing. The third grinding wheel piece 11c is formed by, for example, adhering and fixing 1200th particles for finishing to form a grinding wheel surface 19, respectively. In this case, if the number of the grindstone pieces is small, the size of the particles becomes large and the eyes of the grindstone become rough.

The reduced-diameter portion 7 in the front portion of the first grinding wheel piece 11a is positioned at an angle of about 10 to 40 degrees from an end face X perpendicular to the longitudinal direction of the cylindrical body, and has a grinding wheel. A first guide slope 13a is formed at an angle of 30 degrees with respect to the grindstone surface 19 which is the surface of the piece. Similarly, the reduced-diameter portion 7 in the front portion of the second grinding wheel piece 11b is also positioned at an angle of about 10 to 40 degrees from the end face X perpendicular to the longitudinal direction of the cylindrical body, Further, a second guide slope 13b is provided at an angle of 45 degrees with respect to the grindstone surface 19 of the grindstone piece. Similarly, the diameter-reduced portion 7 in the front portion of the third grinding wheel piece 11c is similarly positioned obliquely at an angle of about 10 to 40 degrees from the end face X perpendicular to the longitudinal direction of the cylindrical body, and A third guide slope 13c is provided at an angle of 60 degrees with respect to the grindstone surface 19 of the grindstone piece. It is preferable that each guide slope is formed as close as possible to the grindstone surface 19 so that the user does not forget the interval between the angles of the guide slope.

The grip 3 of the grinding tool according to the present invention is held by hand, and first, as shown in FIG. 3X, a guide provided on a reduced diameter portion 7 having an angle of 30 degrees for rough finishing. The scissors blade portion 20 is matched with the slope 13a, and the hand is adjusted to the angle of 30 degrees. Next, the scissors are advanced in the direction of the first grindstone piece 11a while maintaining the angle of the guide slope 13a, and are advanced while being lightly pressed against the grindstone surface S, thereby being polished with diamond particles.

In the polishing operation, the rough finishing is completed by a simple operation of moving forward several times. As a result, the rough cutting edges of the scissors are first aligned (Fig. 7). In this case, the grindstone surface S can polish the cutting edge by advancing the blade, but if the grindstone surface is retracted as it is, the diamond particles will be damaged by the blade, so the polishing is performed while retracting. It is necessary not to.

Next, as shown in FIG. 3Y, the blade 20 of the scissors is matched with the guide slope 13 b having a 45-degree angle for medium finishing, and the hand is adjusted to the 45-degree angle. Let Next, the scissors are advanced in the direction of the second grinding wheel piece 11b while maintaining the angle of the guide slope 13b, and repeatedly advanced several times while being slightly pressed against the grinding wheel surface 19, thereby polishing with diamond particles. This allows the scissors blades to be semi-finished with a finer grain than the rough finish grindstone surface (Fig. 7). Usually, this semi-finishing is sufficient.

[0013] Further, the handle portion is held again, and as shown in FIG. 3Z, the scissors blade portion 20 is fitted to the guide slope 13c having a 60-degree angle for finishing, and the hand is adjusted to the 60-degree angle. . Then, the scissors are advanced in the direction of the third grindstone piece 11c while being slightly pressed against the grindstone surface 19 while the angle of the guide slope 13c is kept, so as to finish-grind with fine diamond particles. Since the polishing operation for finishing is completed by a simple operation of moving forward one or two times, that is, several times, the polishing operation can be performed in an extremely short time.

[0014]

[Effect of the invention]

 In the present invention, the blade portion of the scissors is polished with a grindstone piece provided on the surface of the cylindrical body while being held by hand, and the sharpening time of the blade can be restored in a few seconds, which is extremely convenient. It is. In addition, since no water or oil is required for polishing, the scissors are not stained, and the blade other than the scissors can be polished. In particular, polishing is performed while maintaining the contact angle of the blade with the grindstone surface constant.However, since there is a guide slope on the front side of the grindstone surface as a guide, the blade such as scissors is used. Since the object is made to conform to the guide slope and the hand is adjusted to the angle, the object is polished, so that the blade can be polished at the correct polishing angle and the blade edge can be efficiently polished. Because it is good, the sharpness of scissors and the like can be recovered in a very short time.
