Description

  The present invention relates to a cocoon for barber / beauty.

  A typical whisker 9 includes a comb blade body 100 in which a plurality of comb teeth 102 are connected via a comb groove 101, and a bar blade in which a blade edge 93 is a cutting blade from the blade base B to the blade tip P over the entire length. The body 90 is formed by assembling with the pivot axis A (see FIG. 6), and the hair interposed between the blade edge 103 of the comb tooth 102 and the blade edge 93 of the bar blade body 90 in accordance with the closing operation is Although it is cut, the hair that has entered the comb groove 101 is not cut.

  As a kind of such whisker, various kinds of whiskers have been proposed in which a U-shaped, V-shaped or other concave portion is locally formed on the edge of a comb tooth. This is intended to hold the hair in the recess and to reliably cut the held amount of hair. However, with such a configuration, the amount of hair cut at a time is large, and the hairstyle tends to be unnatural. Also, with the closing operation of the heel, discontinuous cutting resistance occurs, and the feeling of use is poor and long-time use is a burden on the user.

  In view of this, there has also been proposed a soot that is intended to reduce the amount of hair captured in the recess by setting the shape and size of the recess (see Patent Document 1). This reduces the amount of hair captured on the blade tip side by making the recess shape semicircular and making the depth of the recess shallower from the blade base to the blade tip or by tilting the recess on the blade tip side. This is intended to reduce the resistance during the closing operation of the bag.

  On the other hand, the present inventor has proposed a scissors with a comb-teeth edge line inclined in a downward direction toward the edge of the comb blade (see Patent Document 2). With this configuration, hair escape is promoted along the inclination of the edge line, so that the amount of hair cut at a time can be reduced, and cutting resistance is reduced. Further, the hair can be cut smoothly due to the effect of so-called drawing (cutting with a scissors).

  However, although the technique of Patent Document 1 can reduce the amount of hair cut to some extent by making the recesses shallow, it is insufficient to reduce the cutting resistance and achieve a smooth sharpness. In addition, with the diversification of hairstyles, whiskers have come to be used for “creating hairstyles” rather than “stripping hair and reducing hair volume”. In connection with this, even in the usage mode of the whisker, in addition to the conventional usage mode in which cutting is performed by moving the blade body on the stationary blade side almost horizontally, the blade body is used by moving in a vertical direction or an oblique direction. It is also being done. For this reason, as described above, with a comb that has a recess on the edge of a comb tooth, there is a problem that when the blade is moved in the vertical direction or in an oblique direction, the hair gets caught in the recess and damages the hair. .

  Further, according to the technique of Patent Document 2, although the amount of hair to be cut at one time is reduced and the hair can be cut smoothly, the hairstyle has a softer finish in recent years. Therefore, there is a demand for a comb that can further reduce the amount of hair cut at a time.

  In addition, in the scissors, the friction between the two blades accompanying the scissors closing operation is not continuous and smooth, but intermittent. That is, the other blade body that rubs against the comb blade body loses an object to be rubbed every time it faces the comb groove portion of the comb blade body, and then collides with the comb teeth that rub against each other. Therefore, there has been a desire for a firewood with reduced impact resulting from such a collision. Further, in the case of the scissors, when the two blades rub against each other, the hair is caught between the blades of the comb teeth, and the hair is easily broken, which may cause split ends and cut hairs.

  Therefore, in view of the above circumstances, the present invention reduces the amount of hair cut at a time, can cut the hair with a smooth cut, and the two blades rub against each other smoothly and damage the hair. It is an object to provide firewood with reduced risk.

  In order to solve the above-mentioned problems, the firewood rod according to the present invention is “a comb blade body in which at least one of two pivotally attached blade bodies has a plurality of comb teeth arranged in series via comb grooves. Each of the comb teeth has a blade-side end formed with a guide protrusion that protrudes from the blade edge of the comb teeth. The cutting edge line reaching the base part of the guide protrusion is not on the virtual blade line connecting the base parts of all the comb teeth, and the edge part on the blade tip side is at a position lower than the virtual blade line. "

  The “blade base side end portion” refers to the end portion on the blade base side among the both end portions of the blade edge of each comb tooth, and the “blade edge side end portion” refers to the end portion on the blade edge side.

  The “virtual blade line” is the blade line when the shape of the comb blade body is captured as a whole, and the “position lower than the virtual blade line” is the same as the other blade body when the heel is closed. It points to a position where the timing of rubbing is later than the point on the virtual edge line.

  The shape of the “cutting edge line” may be a curved line or a straight line as long as the edge part on the cutting edge side is positioned lower than the virtual edge line. For example, when the virtual blade line has an arc shape, the cutting edge line may be an arc shape having a larger curvature than the virtual blade line or an arc shape having a smaller curvature than the virtual blade line. The cutting edge line may be a curve whose curvature changes in the middle. Moreover, about the several comb tooth, the shape of each cutting-blade line may be the same, or may differ.

  In the scissors according to the present invention, the guide protrusions are formed at the blade base side end portions of the respective comb teeth. Contact with. Thereby, the back surface of the guide protrusion has an effect of receiving the other blade body and guiding it in a rubbing manner. Therefore, since the two blades smoothly rub against each other, the closing operation is smooth and the usability is good.

  In addition, most of the hair sandwiched between the two blades tends to slide down along the guide protrusion. Therefore, the possibility that the hair breaks due to the hair being sandwiched in the vicinity of the end portion of the comb-teeth with the closing operation of the heel is reduced. And the cutting edge line is formed so that the edge part on the cutting edge side is at a position lower than the virtual cutting edge line. In other words, the cutting edge line is formed so as to descend to the cutting edge side. The hair tends to run away. As a result, the amount of hair that rolls along the cutting edge line and falls into the comb groove can be increased, and the amount of hair that is cut at a time can be reduced. In addition, since the hair to be cut is cut while rolling along the cutting edge line, the hair can be cut with a smooth sharpness by the effect of cutting with a scissors. In addition, hair that is cut while rolling along the cutting edge line is uneven in length from the hairline, so it can be finished into a hairstyle that gives a soft and natural impression.

  In the present invention, only one of the two blades may be a comb blade, or both blades may be comb blades. In the latter case, it is desirable that the comb groove of one comb blade body and the comb groove of the other comb blade body overlap each other.

  The firewood according to the present invention can be "the length of the cutting edge line is 2 to 6 times the opening width of the comb groove".

  In the conventional scissors, the width of the comb teeth, that is, the length of the comb teeth along the direction from the pivot axis toward the blade edge is generally the same as the width of the comb groove between adjacent comb teeth. Therefore, the length of the cutting edge formed on the edge of the comb tooth is also approximately the same as the width of the comb groove. On the other hand, in the present invention having the above-described configuration, the length of the cutting edge line is considerably longer than that of a conventional whisker.

  As mentioned above, many hairs are easy to slide down along the guide protrusions, and the hair tends to roll along the cutting edge line toward the cutting edge. The effect of cutting may not be obtained sufficiently. In the present invention, by making the length of the cutting edge line considerably longer than that of the conventional whisker, it is possible to obtain a sufficient effect of cutting smoothly while escaping the hair, and to some extent the number of hairs to be cut. Can be secured. In addition, by adjusting the length of the cutting edge line in the range of 2 to 6 times the opening width of the comb groove, it is easy to make a cocoon with a desired amount of hair to be cut at a time Can be designed and manufactured.

  Here, if the cutting edge line is lengthened, the width of the comb teeth naturally increases, but if you want to avoid the increase in the mass of the whole whisker accompanying this, even if you reduce the width of the comb teeth in the middle part of the comb teeth good. In other words, the opening width of the comb groove is kept as it is, and the width of the comb groove is made deeper than that. Alternatively, the mass of the entire ridge can be suppressed by forming a long hole that penetrates the comb teeth.

  As described above, as an effect of the present invention, the amount of hair cut at a time can be reduced, the hair can be cut with a smooth sharpness, and the two blades rub against each other smoothly and may damage the hair. Can be provided.

It is the principal part front view and partial enlarged view of the soot bowl of 1st embodiment. It is explanatory drawing which illustrates the other shape of a cutting-blade line. It is the principal part front view and partial enlarged view of the soot bowl of 2nd embodiment. It is the principal part front view and partial enlarged view of the soot of a third embodiment. It is a principal part front view at the time of forming a long hole part in the comb-tooth of the cocoon of the first embodiment. It is a front view explaining the structure of the conventional firewood.

  Hereinafter, the firewood 1 which is 1st embodiment of this invention is demonstrated based on FIG. The scissors 1 is a scissors 1 in which one of two pivotally attached blades is a comb blade 10 in which a plurality of comb teeth 12 are connected via a comb groove 11. A guide protrusion 14 in which the blade edge of the comb tooth 12 protrudes is formed at the blade base side end portion 17 of the tooth 12, and the base portion of the guide protrusion 14 from the blade edge side end portion 18 of each comb tooth 12. The cutting edge line 15 reaching 14b is not on the virtual blade line L1 connecting the base parts 14b of all the comb teeth 12, and the blade edge side end 18 is at a position lower than the virtual blade line L1. is there. In addition, the length of the cutting edge line 15 is formed to be about three times the opening width W1 of the comb groove 11.

  More specifically, in the scissors 1 of the first embodiment, the virtual blade line L1 has an arc shape, and the cutting edge line 15 is formed in an arc shape having a larger curvature than the virtual blade line L1. Moreover, in 1st embodiment, the virtual line L11 which tied the guide protrusion 14 tip of each comb tooth 12 is also circular arc shape. The “arc shape” here is not limited to a part of the circumference of a perfect circle, but is meant to include a part of the circumference of an ellipse or a curve that bends smoothly in one direction.

  Further, in the scissors 1, the stationary blade is the comb blade body 10, and the moving blade is the rod blade body 80 in which the cutting edge line 83 is formed over the entire length. In the comb blade body 10, the plurality of comb grooves 11 are formed in a concentric arc shape with the pivot axis A as the center. Moreover, in this embodiment, the width | variety of each comb tooth 12 is substantially the same, and the width | variety of the comb groove 11 is also substantially the same from the blade base to the blade edge | tip.

  In the scissors 1 having such a configuration, the back surface of the guide protrusion 14 receives and guides the rod blade body 80 in accordance with the closing operation, so that the friction between the two blade bodies is smooth and the usability is good. In addition, if the back surface of the guide protrusion 14 is formed so as to be chamfered in the escape direction with respect to the contact with the rod blade body 80, the above-described guide action is more effectively exhibited.

  In addition, most of the hair sandwiched between the comb blade 10 and the rod blade 80 is likely to slide down along the guide protrusion 14. Therefore, the possibility that the hair is sandwiched near the blade end 17 and the hair is broken is reduced. Since the cutting edge line 15 is formed in an arc shape having a larger curvature than the virtual blade line L1, and the cutting edge side end 18 is formed at a position lower than the virtual blade line L1, The hair that has slid down along the guide protrusion 14 is more likely to escape toward the blade edge along the cutting edge line 15. As a result, the amount of hair falling into the comb groove 11 can be increased, the amount of hair to be cut at a time can be reduced, and the cut hair can be cut while rolling along the cutting edge line 15, so that the hair is smooth. The hair can be cut with a sharp edge. Moreover, since the length of the hair that is cut while rolling along the cutting edge line 15 is uneven, a soft and natural hairstyle can be finished.

  Furthermore, in this embodiment, the virtual blade line L1 is arcuate. Here, in the eyelid, the larger the open angle of the two blade bodies (hereinafter referred to as “scissors angle”), the easier the hair escapes in the direction of the blade edge with the closing operation of the eyelid. For example, in a ridge with a straight blade, the scissor angle decreases with the closing operation, so that the hair is easy to escape on the blade side, and the hair is sandwiched between two blades on the blade side and cut. Easy to be. On the other hand, when the blade line is in an arc shape as in this embodiment, there is almost no change in the scissor angle accompanying opening and closing of the two blade bodies, so that the hair can easily escape from the blade base side to the blade tip side. Can be made comparable. That is, the amount of hair to be cut at a time can be reduced, and the amount of hair to be cut tends to be uniform regardless of the position of the cutting blade line 15 at which the hair is cut.

  Furthermore, since the length of the cutting edge line 15 is considerably longer than about 3 times the opening width W1 of the comb groove 11, the presence of the guide protrusion 14, the shape of the cutting edge line 15, and the virtual edge of the edge as described above. Even if the hair is very easy to escape due to the shape of the line L1, the number of hairs to be cut by the cutting blade line 15 is ensured, and the effect of cutting smoothly while releasing the hair is sufficiently exhibited. be able to. Specifically, the length of the cutting edge line 15 is 2.5 mm to 4.5 mm, which is considerably longer than the length of the blade edge of the comb tooth of the conventional whisker 1 to 1.5 mm. ing.

  In addition, as shown in FIG.1 and FIG.2 (a), as for the shape of the cutting-blade line 15 in 1st embodiment, a part bulges slightly from the virtual blade line L1, and it is a curvature from the virtual blade line L1. However, the present invention is not limited to this as long as the cutting edge side end 18 is at a position lower than the virtual blade line L1. For example, as shown in FIG. 2B, the virtual blade line L1 has an arc shape with a larger curvature than the virtual blade line L1, and extends from the base part 14b of the guide protrusion 14 to the blade edge part 18 over the entire length. The cutting edge line 15b can be made lower. Alternatively, as shown in FIG. 2C, an arcuate cutting edge line 15c having a smaller curvature than the virtual edge line L1 may be used. FIG. 2C illustrates a case where the radius of curvature is approximately 10% larger than the virtual edge line L1.

  In addition, when the cutting edge line is arcuate, the arcuate shape may be reversed in the direction of bending as shown in FIGS. For example, as shown in FIG. 2 (d), a reverse arcuate cutting edge line 15d that smoothly draws an arc as a whole can be obtained. As in this example, when an arc is smoothly drawn toward the cutting edge 18 that is lower than the virtual cutting line L1, the action of holding the hair is not substantially achieved even in the reverse arc shape, The action of escaping to the cutting edge side acts preferentially. Furthermore, it is not limited to the curved shape that bends smoothly in one direction like the cutting edge lines shown in FIGS. 2 (a) to 2 (d), and as shown in FIG. 2 (e), the curved shape in which the curvature changes midway. The cutting edge line 15e can also be used. In addition, the shape is not limited to an arc shape or a curved shape, and may be a straight cutting edge line 15f as shown in FIG.

  Next, the firewood 2 of 2nd embodiment is demonstrated using FIG. The scissors 2 are the scissors 2 in which one of the two blades pivotally attached is a comb blade 20 in which a plurality of comb teeth 22 are connected via a comb groove 21. A guide protrusion 24 in which the blade edge of the comb tooth 22 protrudes is formed at the blade base side end portion 27 of the tooth 22, and the base portion of the guide protrusion 24 from the blade edge side end portion 28 of each comb tooth 22. The cutting edge line 25 leading to 24b is not on the virtual blade line L2 connecting the base parts 24b of all the comb teeth 22, and the blade edge side end 28 is at a position lower than the virtual blade line L2. is there. In addition, the length of the cutting edge line 25 is formed to be 3 to 4 times the opening width W2 of the comb groove 21.

  More specifically, in the scissors 2 of the second embodiment, the virtual blade line L2 has an arc shape, and the cutting edge line 25 is formed in an arc shape having a larger curvature than the virtual blade line L2. In the second embodiment, the imaginary line L22 connecting the tips of the guide protrusions 24 of the comb blades 12 is also arcuate.

  In the scissors 2, the stationary blade is the comb blade body 20, and the moving blade is a rod blade body 80 in which a cutting edge line 83 is formed over the entire length. In the comb blade body 20, the plurality of comb grooves 21 are formed in a concentric arc shape with the pivot axis A as the center, and the groove width is wider in the comb groove 21 than the opening at the blade edge as viewed from the front. It is formed in a substantially elliptical shape. Accordingly, each comb tooth 22 extends in the middle portion from the base end connected to the adjacent comb tooth 22 to the blade edge, and the blade edge side is directed toward the blade edge because the comb groove 21 is expanded inside. It has a wide inverted triangle shape.

  In the soot 2 having such a configuration, as in the first embodiment, the amount of hair to be cut at a time can be reduced, the hair can be cut smoothly while escaping, and the two blade bodies 20, 80 are smooth. The risk of damaging the hair is reduced.

  In addition, in the second embodiment, since the width of the comb groove 21 is larger on the inner side than the opening width W2, it is possible to prevent the width of the comb tooth 22 from being increased as the cutting edge line 15 is increased. Thus, an increase in the mass of the whole firewood 2 is suppressed. Further, in the second embodiment, since the space in the comb groove 21 is wide and a large amount of hair is accommodated, the amount of hair cut at a time can be reduced, and the space in the comb groove 21 is wide, so The hair that has not been removed is easily removed from the comb blade body 20.

  Next, the firewood bowl 3 of 3rd embodiment is demonstrated using FIG. In this whip 3, both of the two blades pivotally attached are comb blades. In the first comb blade body 30, a plurality of comb teeth 32 are connected via a comb groove 31, and a blade edge of the comb teeth 32 protrudes from a blade base side end portion 37 of each comb tooth 32. The guide protrusions 34 are formed, and the cutting line 35 extending from the blade edge side end portion 38 of each comb tooth 32 to the base portion 34b of the guide protrusion 34 connects the base portions 34b of all the comb teeth 32. It is not on the virtual blade line L3, and the blade edge side end portion 38 is at a position lower than the virtual blade line L3. In addition, the length of the cutting edge line 35 is formed to be about three times the opening width W3 of the comb groove 31.

  More specifically, in the scissors rod 3 of the third embodiment, the virtual blade line L3 has an arc shape, and the cutting edge line 35 is formed in an arc shape having a larger curvature than the virtual blade line L3. In the third embodiment, the imaginary line L33 connecting the tips of the guide protrusions 34 of the comb blades 32 is also arcuate.

  In the second comb blade body 40, a plurality of comb teeth 42 are connected via a comb groove 41, and the comb groove 41 is formed at a position overlapping the comb groove 31 of the first comb blade body 30. . Here, the cutting edge line 43 is formed along the edge of each comb tooth 41. In addition, the 2nd comb blade body 40 is not provided with the structure corresponded to a guidance protrusion.

  More specifically, the first comb blade body 30 is a stationary blade and the second comb blade body 40 is a moving blade. The plurality of comb grooves 31 and the plurality of comb grooves 41 are formed in a concentric arc shape with the pivot axis A as the center. In the present embodiment, the widths of the plurality of comb teeth 32 and the plurality of comb teeth 42 are the same, the width of the comb teeth 32 and the width of the comb teeth 42, and the width of the comb grooves 31 and the width of the comb grooves 41. The blade edge to the blade edge are almost the same.

  According to the soot 3 having such a configuration, as in the first embodiment and the second embodiment, the amount of hair to be cut at a time can be reduced, and the hair can be cut smoothly while escaping. The blade bodies 30, 40 rub against each other smoothly and the risk of damaging hair is reduced.

  In addition, in the comb 3 of the third embodiment, the comb groove 31 of the first comb blade body 30 and the comb groove 41 of the second comb blade body 40 overlap with each other in accordance with the closing operation, so that the blade hit when the hair is pulled out. There is no risk of hair damage. In addition, when the two comb blades 30 and 40 are closed, the comb groove 31 and the comb groove 41 communicate with each other to form a large space, so that the hair spreads in this space and can be extracted very easily. Can do. Further, as in the above-described embodiment, since the comb grooves 31 and 41 are concentric arcs with the pivot axis A as the center, the opening and closing operation of the heel, that is, the comb blade body with the pivot axis A as the center With the rotational movements 30, 40, the hair in the comb grooves 31, 41 is less likely to rub against the side walls of the comb grooves, and hair damage due to friction is reduced.

  The present invention has been described with reference to the preferred embodiments. However, the present invention is not limited to the above-described embodiments, and various improvements can be made without departing from the spirit of the present invention as described below. And design changes are possible.

  For example, when the comb teeth are wide as in the first embodiment and the third embodiment, a long hole portion 19 penetrating the comb teeth 12 may be provided as shown in FIG. By doing in this way, the mass of the comb blade body 10b becomes light, and the burden concerning a user's hand is reduced. Here, FIG. 5 exemplifies the firewood 1b whose configuration other than the long hole portion 19 is the same as that of the first embodiment. As shown in the figure, if the width of the long hole portion 19 is made substantially the same as the width of the comb groove 11 and the long hole portion 19 is formed so as to have a concentric arc shape with the pivot axis A as the center, like the comb groove 11, The appearance is also beautiful.

  Further, in the above embodiment, the case where the shape of each cutting blade line is the same in a plurality of comb teeth of one whisker is illustrated and illustrated, but the present invention is not limited to this, and the position from the blade base to the blade edge The shape of the cutting edge line may be changed according to the above. By adopting such a configuration, it is possible to adjust the slipperiness of hair and the amount of hair that rolls along the cutting edge line and falls into the comb groove according to the position from the blade edge to the blade edge. For example, by gradually increasing the curvature of the arcuate cutting edge line from the cutting edge toward the cutting edge, the amount of hair cut at a time can be reduced.

  Furthermore, in the above-described embodiment, the case where the width of the comb teeth and the length of the cutting edge line are equal is illustrated and illustrated for a plurality of comb teeth of a single firewood. May be changed according to the position from the blade edge to the blade edge. With such a configuration, the amount of hair to be cut while rolling along the cutting edge line can be adjusted according to the position from the blade edge to the blade edge. For example, the amount of hair to be cut can be reduced by reducing the width of the comb teeth from the blade base toward the blade tip.
