A replaceable edge of a hair combing razor, comprising a lengthwise sheet edge and a two-folded holding sheet for holding the sheet edge from the rear, an edge side of the holding sheet being provided with a corrugation that covers at least one of the front and rear sides of the tip of the sheet edge so as to alternate exposed portions and non-exposed portions by a sliding means also provided to the replaceable edge in order to allow the sheet edge to slide for alternating non-exposed portions and exposed portions, the non-exposed portions being a specified size wider than the exposed portions. The replaceable edge, designed to allow the edge tip (11) to longitudinally slide within the holding sheet so that an edge tip used as a non-exposed portion (Y)can be used as a new exposed portion (X), permits unused edge tips of non-exposed portions to be used a plurality of times in a divided manner due to non-exposed portions that are wider than exposed portions, thereby providing several times longer service life than one that does not allow sliding.

Description

Kida: Leather replacement blade for combing and its storage case

The present invention relates to a leather replacement blade used for combing hair and an improvement in a storage case for the replacement blade. Background art

At a barber shop, a combing leather R as shown in Fig. 13 is used as one of the combing methods. The leather R for combing is of a replaceable blade type, and the replaceable blade 300 has a long plate blade 10 as shown in FIG. 0, the corrugation formed on the edge 21 of the holding plate 20 covers the cutting edge 11 of the plate blade 10, so that the exposed portion where the cutting edge 11 is exposed, and the cutting edge And the non-exposed portions Y covered by are alternately formed. In the past, there was a time when shaving leather was diverted to combing hair, but this was because the shaving leather had all the blades exposed and tended to comb too much hair. To obtain the above-mentioned leather for combing hair. According to this, since the cutting edge 1 1 is covered by the corrugated ridge 27 of the edge 24 of the narrow holding plate 20, the amount of hair combing can be suppressed as compared with the leather for shaving. .

However, in the replacement blade as shown in Fig. 14, only the portion where the cutting edge is located at the exposed portion is used, and the cutting edge located at the non-exposed portion is not used. Therefore, when the blade became dull and was replaced with a new blade, the blade at the non-exposed portion was discarded unused. Accordingly, the applicant of the present application has filed a patent application for non-exposed areas, which have not been used in the past, according to Japanese Patent Application Nos. 7-678447, 9-73, 771 and 10-14,461. A replacement blade 400 for hair combing leather as shown in Fig. 15 has been proposed which has been improved so that the blade tip can also be used. One of the special blades of the replacement blade 400 is that the blade 11 of the plate blade 10 slides in the longitudinal direction in the holding plate, and the blade which was not exposed becomes a new exposed portion. X, that is, it is formed so that the exposed portion X and the unexposed portion Υ are alternated. You. Also, in order to realize such a thing, a transparent window portion is provided in the holding plate, and a plate blade corresponding to this window portion has a locking portion for locking and sliding the plate blade. The plate blade is shorter than the narrow plate in order to provide a margin for the plate blade to slide in the holding plate. By replacing the exposed part X and the non-exposed part Y in this manner, the life of the replacement blade is extended. The replacement blade is sold, for example, as a case of 10 pieces. This storage case has a projection that pushes the plate blade when sliding. Is also provided. However, with conventional replacement blades whose edges are simply covered with a corrugation as shown in Fig. 13--15, the amount of combing is constant. Even if there are various requests such as cases, it is difficult to adjust the amount of such carding.

In addition, since this replacement blade is formed by holding the plate blade sandwiched between the narrow holding plates, it does not shift in this narrow holding plate during normal use, but it is not exposed to the exposed part of the cutting edge. When sliding the blade to replace the edge, if the edge shifts in and out of the edge, the blade edge will increase or decrease in the exposed part, and as a result, the hair combed in this exposed part The amount of combing may increase or decrease, and may eventually differ from the planned amount of combing.

Therefore, an object of the present invention to solve the above problems is to replace the blade with a smaller amount than the conventional blade, or to adjust the amount of combing to a desired amount according to the design of the hair. Replaceable blades that have a blade that can slide or a blade that has a sliding means of a plate blade that can maintain a constant amount of combing, and a leather for hair combing that has a sliding means of a plate blade that can adjust the increase or decrease of the exposed portion. The replacement blade is provided. Disclosure of the invention

The present invention relates to a hair-combing leather replacement blade in which a plate blade is held by a holding plate, and the edge of the plate blade is covered with a waveform of an edge of the holding plate, and an exposed portion and a non-exposed portion are alternately formed. It is about.

In order to solve the above-mentioned problem, according to the invention described in claim 1, the non-exposed portion is located closer to the exposed portion. A means for forming a fixed width is provided. In other words, in the past, the exposed edge and the unexposed portion of the blade edge were the same size, so shifting the plate blade once would double the service life compared to the non-slipped blade. In contrast, in the present invention, the size of the exposed part and the non-exposed part are different, and the non-exposed part is wider than the exposed part, so that the unused cutting edge of the non-exposed part can be used in plural times, According to this, the life of the replacement blade can be made longer than twice the conventional one.

For example, if the width of the non-exposed part is formed to be three times the width of the exposed part, the blade edge of the non-exposed part can be used 3 'times, and the service life is longer than that of a replacement blade that does not shift the plate blade. Is quadrupled.

In this way, the life of the replacement blade can be greatly extended.

In addition, since the width of the blade edge of the exposed portion is formed to be narrow, the amount of combing can be reduced. For example, if you prepare multiple replacement blades with different widths of the exposed part, such as 50% width, 30% width, and 10% width of the waveform pitch width, the user can use these replacement blades properly. It is possible to work with a desired combing amount. Further, the invention according to claim 2 proposes a sliding means for the plate blade, that is, at least one end of the holding plate is cut out to provide a window, and the side of the plate blade exposed from the window is provided. The plate blade is slid by pushing the pushing portion at the end with a predetermined projection or the like. At that time, in the invention according to claim 3, the window portion is provided with a step portion having a depth corresponding to a predetermined pushing amount.

With this, when the plate blade is pushed in by applying a projection or the like to the pushing portion, the pushing amount can be selected by pressing the projection or the like to a desired one of the steps. As a result, the plate blade can be slid by a predetermined amount.

In the above example of claim 1, an example of shifting three times is shown, but for example, a step portion having three steps with a depth corresponding to the three sliding amounts is provided. The plate blade can be slid a total of three times by sequentially pushing it into each step from the shallow step. Since the step restricts the sliding of the plate blade in this manner, the unused blade edge in the non-exposed portion can be used a plurality of times. Further, in the invention according to claim 4, the plate blade is prevented from being displaced from the edge of the holding plate in and out. That is, according to the present invention, a protruding portion provided on the inner surface of the holding plate and facing the side surface of the plate blade, and a guide portion which engages with the protruding portion to guide the movement of the plate blade only in the longitudinal direction. With this configuration, the plate blade can be accurately slid in the longitudinal direction. Therefore, when the plate blade is moved in the longitudinal direction, it is possible to prevent the plate blade from being displaced from the edge of the holding plate in and out of the holding plate, and consequently, the deviation of the exposed portion does not occur. As a result, the combing amount is kept constant. In addition, this prevents the edge from protruding from the edge of the waveform, so that the operator does not accidentally cut his hand at the protruding edge.

Further, in the invention according to claim 5, since the guide portion is provided so as to guide the sliding of the plate blade in an oblique direction, it is possible to arbitrarily adjust the entry and exit of the blade edge with respect to the edge of the waveform, and It is possible to adjust the increase or decrease of the exposed portion according to a desired combing amount. Claims 6 to 8 are inventions dependent on Claims 13 to 13. In order to reduce the amount of combing, in addition to the above-described Claims 13 to 13, a waveform is produced during the carding operation. Thus, a concave portion for capturing a part of the hair guided to the exposed portion was formed by the holding plate. According to this measure, a part of the hair is caught in the concave portion, and not all of the hair is collected in the exposed portion. The means in claims 6 to 8 in which the replacement blade has a recess may be made dependent on claims 4 and 5 as well as claims 13 and 13. ■ Further, the means of claims 6-8 in which the replacement blade is provided with a concave portion may be used as an independent invention as in claim 911, without depending on claim 113. In this case, unity is secured by the purpose and the problem of reducing the amount of carding. The invention described in claim 12 is an invention of a storage case for accommodating a spare blade, and aims at sliding the spare blade of claim 2-3.

In other words, different protruding lengths are provided to provide By pressing the side edge of the plate blade from the window using the protrusion, the plate blade can be slid with an accurate pushing amount corresponding to the protruding length, and both sides are pushed. There is no need to procure possible separate components. In addition, by selecting the protrusion, the amount of pushing, that is, the amount of sliding can be selected, so that the amount of sliding does not mistake. BRIEF DESCRIPTION OF THE FIGURES

Next, an embodiment of a replacement blade for a hair combing leather according to the present invention will be described based on an embodiment shown in the drawings.

Embodiment 1 FIG. 1 shows an embodiment of the replacement blade according to claim 13. The replacement blade 100 A is composed of a long plate blade 10 and a two-folded holding plate 20 for holding the plate blade 10 from the back side, and the edge 2 1 of the holding plate 20 is formed. Has a waveform, and is formed so that the exposed portion X and the non-exposed portion Y are alternately repeated by covering one surface of the cutting edge 11 of the plate blade 10 with the waveform. In addition, a window 22 as a sliding means for sliding a plate blade to alternate between the exposed portion X and the non-exposed portion Y is formed at the longitudinal end of the holding plate 20 with a stepped portion 23. Have been. The width Yw of the non-exposed portion Y is formed wider than the width Xw of the exposed portion X, and the exposed portion X of the replacement blade 10OA is formed with a width of 30% of the pitch width. Therefore, when the exposed portion X is formed with a width of 30% of the pitch width W, the non-exposed portion Y is formed with a width of 70% of the pitch width W. The window 22 has a depth substantially equal to the width Yw of the non-exposed portion Y. To change the exposed portion X and the non-exposed portion Y, the plate blade 10 should be moved by the width X w of the exposed portion, but the width Y w of the non-exposed portion Y becomes the width X w of the exposed portion X. The window 22 of the replacement blade 10 OA is provided with two step portions 23 so that the plate blade 10 slides twice. Then, the plate blade 10 can slide the plate blade 10 on the second floor from the position shown in FIG. 1 (a) as shown in FIGS. 1 (b) and (c). The blade edge 1 1 can be used twice. The replacement blades 100 B and 100 C shown in FIGS. 2 (a) and (b) are examples of the invention described in claim 8 which is dependent on claims 1-3, and are shown in FIG. 1 respectively. Spare blade 1 0 0 The corrugation of A is provided with a concave portion 24 for catching the hair when combing the hair. The recess 24 of the replacement blade 10 OB in FIG. 2 (a) is trapezoidal, and the recess 24 of the replacement blade 100C in FIG. 1 (b) is semicircular. (Embodiment 2) FIG. 3 shows a replacement blade 100D-10OF of the embodiment of the invention according to claim 4, and most of the configuration is the same as the replacement blade 100A-100C shown in FIG. 1 and FIG. . The difference is that the clamping plate 20 has a projection 26 on the inner surface 25 (see FIG. 4), and the side surface 12 of the blade 10 engages with the projection 26 to allow the blade 10 to slide only in the longitudinal direction. This is the point that a guide portion 13 is provided. The guide portion 13 is composed of a long hole 13 ″ penetrated through the plate blade 10, and the long holes 13 are arranged in parallel with the cutting edge direction L. The protruding portion 26 is welded at its front end to the opposite face by spot welding, and is formed as a continuous portion 26 'that connects the inner surfaces of the holding plates. Further, the elongated holes 13 and of the guide portion 13 are engaged with the continuous portion 26 'to restrict the plate blade 10 from shifting in a direction other than the longitudinal direction. Therefore, even when the plate blade 10 slides, the blade edge 11 of the plate blade 10 does not slip out of the edge 21 of the holding plate 20 (S in FIG. 3A). Therefore, the width Xw of the exposed portion X does not change widely, that is, the combing amount is kept constant.

In addition, since the plate blade 10 does not come in and out of the edge 21, the blade edge 11 does not come out and is safe against danger of cutting hands. In addition, if the protruding portion 26 merely protrudes into the holding plate 10, when the protruding portion 26 comes into contact with one longitudinal end of the guide portion 13, the force for sliding is reduced. Even if the protruding part 26 gets over one end and slides too much due to too strong, etc., if there is an erroneous operation, if it is connected by spot welding as in this embodiment, there is no risk of getting over and erroneous operation. .

(Example 3)

FIG. 5 shows the replacement blade 100G-100J of the embodiment of the invention described in claim 4, similarly to the second embodiment, and most of the configuration is the same as the replacement blade 100 shown in FIG. The difference is that the width Xw of the exposed portion X is formed to be 10% of the pitch width W. Window portions 22 and 22 ′ are formed at both ends of the holding plate 10 with step portions 23.

In the replacement blade 100G-100J of the present embodiment, the width Xw of the exposed portion X is formed as narrow as 10% of the pitch width W, so that the blade can be used seven times by sliding six times. (Note that if the exposed portion width Xw is 10% of the pitch width W, theoretically 10 times (= 100% ÷ 10%) can be used, but 7 times in total considering the sliding error To use it). If a step 23 having a depth corresponding to each of the six drive widths is formed only in one window 22, it is difficult to form the step because the step is too fine, and the windows 22, 22 are provided at both ends of the holding plate 10. 22, are provided. Each of the windows 22, 22, at both ends has a step 13 formed in three steps. First, the exposed portion X and the non-exposed portion Y can be replaced three times by pushing the pushing portion 14 from one window portion 22. When the push-in portion 14 reaches the deepest portion of the step portion 13, the push-in portion 14 'appears in the other window portion 22', so that the plate blade 10 is pushed back from the push-in portion 14 'and is slid every step portion 23'. It can be changed three more times by moving, for a total of seven uses.

Explaining with reference to FIG. 6, when the plate blade 10 is slid from one of the windows 22, portions of the cutting edge 11 that were initially in the non-exposed portion Y are located at Al, A 2 and A 3. Used as the exposed part X sequentially. Next, when the plate blade 10 is pushed back from the other window portion 22 'and slid, the portions located at B1, B2 and B3 of the cutting edge 11 which was initially at the non-exposed portion Y are sequentially used. By using the windows 22, 22 'provided at both ends of the holding plate 10 in this manner, the exposed portion X and the non-exposed portion Y can be replaced six times.

(Embodiment 4) FIG. 7 shows an embodiment of the replacement blade according to claim 5. This replacement blade 100K has a guide portion 26 formed so as to guide the sliding of the plate blade 10 in an oblique direction, so that the blade edge 11 can come and go arbitrarily from the edge 21 of the holding plate 20 (see FIG. The carding amount can be adjusted by increasing or decreasing the width of the exposed portion X using the symbol S). As described above, the replacement blade 100K of the present embodiment is configured such that the sliding of the plate blade 10 can be applied to adjust the movement of the blade edge 11 in and out. More specifically, the guide portion 26 is a long hole 26 ′ penetrating through the plate blade 10, and the long hole 26 ′ is arranged slightly obliquely to the cutting edge line L. Windows 22 and 22 are provided at both ends of the holding plate 10, and the windows 22 and 22 'have steps 13 and 13' formed in four steps. Further, since the plate blade 10 slides obliquely, a sufficient clearance is secured between the back portion 15 of the plate blade 10 and the inner surface of the holding plate N to allow the plate blade 10 to enter and exit. When one of the pushing portions 14 is pushed in from the position of the plate blade 10 in FIG. 7 (a) with a projection, the plate blade 10 slides obliquely upward and rightward as shown in FIG. Since the width Xw of the fiber is reduced, the amount of combing can be reduced. Also, since the step portion 23 is formed in four steps, the replacement blade 100K of the present embodiment can select four levels of combing amount. In order to return the exposure amount once reduced to the original value, the other push-in portion 14, may be pushed in.

Further, the replacement blades 100L, 1M shown in the present embodiment may be provided with a concave portion 24 at the peak as shown in FIGS. 8 (a) and 8 (b).

(Embodiment 5) FIG. 9 shows an embodiment of the replacement blade according to claim 7. The replacement blade 10ON has corrugations on the front and back edges 21, 21 'of the holding plate 10, and has a concave portion 24 formed by the corrugations. Specifically, the two ridges 27, 27 are shifted by the fact that the ridges 27 of the front side edge 21 and the ridges 27 'of the back side edge 21' are slightly offset from the position where they overlap each other. A recess 24 is formed between and.

(Embodiment 6) FIG. 10 shows an embodiment of the replacement blade according to claim 8. This replacement blade 100P also has waveforms on the front and back edges 21, 21, of the holding plate 10 so that the peaks 27, 27 'on the front and back are alternately arranged with the valley 28 interposed therebetween. Is formed. The exposed portion X where both surfaces of the cutting edge 11 are exposed, and the non-exposed portion Y where one surface of the cutting edge 11 is covered with the ridges 27 and 27 'are alternately formed.

The concave portions shown in the fifth embodiment and the sixth embodiment may be provided in the replacement blade shown in the first to fourth embodiments. (Embodiment 7) Next, an embodiment of a storage case for a replacement blade of a hair combing leather according to the present invention will be described with reference to the drawings.

FIGS. 11 and 12 show a storage case 200 for the replacement blade of the hair combing leather shown in Examples 15 to 15. The storage case 200 is made of a flat box 30 made of plastic and opened upward, and a rectangular cylindrical outer case 40 into which the flat box 30 is inserted. The inside of the flat box 30 is The replacement blade 100 is formed so that the blade edge 21 of the replacement blade 100 can be stored upright, and specifically, is provided with a stand 44 that stands between both ends and a central portion of the replacement blade 100. Further, as shown in FIGS. 11-1 and 12, one end of the flat box 30 is formed with three protrusions 41, 42 and 43 having different protruding lengths, each of which has a blade 1 It has protrusion lengths H1, H2, and H3 according to the sliding amount of 0.
