Description

The present invention relates to a tweezers type waste hair cutting including a tweezers main body and a coil spring.

Various unwanted hairs grow on the human body in various places and regardless of age, regardless of gender. I want to remove these unwanted hairs if they grow on the shins and other parts that are easily visible, and if they grow on the nostrils and nostrils, I want to remove them as well.

As a device or device for removing such waste hair, a razor or a shaving can be mentioned first, but various other devices and devices such as those using a laser beam have been conventionally proposed. For example, even if it is limited to the manual type that the user himself / herself holds and uses, the “spring type” as shown in Patent Documents 1 and 2 and FIG. 7 of the present application is known.

Japanese Unexamined Patent Publication No. 2001-327322, Summary, Representative Diagram Japanese Unexamined Patent Publication No. 2004-215967, abstract, representative drawing

The "hair removal device" proposed in Patent Document 1 is intended to "provide a cosmetic hair removal device capable of easily pulling out hair by hand-held operation", and is made in FIG. 7 (a). ) Is provided, "a holder 16 that can move back and forth holding the holding metal fitting 15 so that the tip portion faces the opening 4, and a slider 17 that holds the hair in the holding metal fitting 15 by moving backward". It is necessary to provide a large number of members for covering and driving members. On the other hand, the "hair remover" proposed in Patent Document 2 relates to the "hair remover 10 having the tweezers element 12" as shown in FIG. 7 (b), and at least the surface of the tweezers element 12 is at least. It is made at least partially with a basic material that is reinforced with 30% filling material. The basic material that is reinforced with the filling material has a hardness of at least 3 in Mohs hardness. " It is configured as a thing.

The "spring type" hair remover proposed in Patent Documents 1 and 2 moves the entire device by grasping the waste hair with a compressed spring as shown in (a) or (b) of FIG. It is thought that it is possible to remove the unwanted hair by letting it go, but it is not possible to remove the unwanted hair locally because it is difficult to see the unwanted hair gripped by the spring, and because the entire device is large, the ear canal and It is considered that it cannot be inserted into the nose and the waste hair in these cannot be pulled out or cut.

In addition, the "spring type" hair remover proposed in Patent Documents 1 and 2 is considered to cause a slight pain in the skin because it "extracts waste hair" to the last, and is generally used if possible. It is good to have a "smooth feeling" like a razor or shave.

Of course, since the "spring type" hair remover proposed in Patent Documents 1 or 2 requires a member for driving the spring portion, not only the entire device is enlarged, but also the entire device is enlarged. It is complicated as a whole, such as the need for a power supply. On the other hand, in general razors and shavings, the so-called "T-shaped" or "L-shaped" is often shaped so that it cannot be inserted into the ear canal or nostril, and it is not possible to remove unwanted hair in these. It is thought that it cannot be done.

Therefore, the present inventors can fully utilize the advantages of "tweezers" and "coil springs", and can perform local waste hair cutting with a smooth feeling while making the structure very simple. As a result of repeated studies on how to do this, the present invention has been completed.

That is, the object of the present invention is that when the "coil spring" is compressed by the "tweezers", the waste hair can be firmly grasped, and even if it is a local waste hair cutting, the "tweezers" is used. The purpose is to provide a simple structure for waste hair cutting that can be performed with a smooth feeling while fully utilizing the advantages of the "coil spring".

Another object of the present invention is that when the "coil spring" is compressed by the "tweezers", each coil portion constituting the coil spring can be prevented from being displaced locally. The purpose is to provide a simple structure for waste hair cutting that can be performed with a smooth feeling while making full use of the advantages of "tweezers" and "coil springs" even if it is a waste hair cutting.

In order to solve the above problems, first, the means adopted by the invention according to claim 1 will be described with reference numerals used in the description of the best form described later.
"By sandwiching a pair of tweezers arms 11 facing each other with fingers, the tweezers main body 10 that closes the tip portions 12 of these tweezers arms 11 and the tip portions 12 of each tweezers arm 11 are attached to each tip portion 12 A tweezers-type waste hair trimmer 100 composed of a coil spring 20 that is compressed when the arm is closed.
For each coil portion 21 constituting the coil spring 20, a contact plane 22 substantially orthogonal to the compression direction is formed on one side surface in the compression direction, and a protrusion protruding toward the contact plane 22 on the other side surface. When the tweezers 23 are formed and the coil spring 20 is compressed, each tweezers 23 is brought into contact with each abutting plane 22 of each coil portion 21, and between these abutting planes 22 and the tweezers 23. Tweezers-type waste hair cutting 100, which is characterized by cutting the waste hair that has entered. "
Is.

That is, as shown in FIG. 1, the waste hair cutting 100 according to the present invention is a compression spring between the outer end portions 12 of the pair of tweezers arms 11 constituting the tweezers main body 10 having a general tweezer shape. A coil spring 20 is attached, and the tweezers arm 11 is sandwiched between fingertips to compress the coil spring 20 at the tip. Further, the length of the coil spring 20 used in the waste hair cutting 100 in the compression direction in the uncompressed state (in the vertical direction shown in FIG. 1A) is the maximum in other parts. Moreover, it can be inserted into the nostrils and ear canals. That is, the coil spring 20 of the waste hair cutting 100 can be inserted into the nostril or ear canal as it is in the state shown in FIG.

Further, as shown in FIGS. 2 to 4, each coil portion 21 of the coil spring 20 constituting the waste hair cutting 100 has a contact plane substantially orthogonal to the compression direction on one side surface of the compression direction. When the coil spring 20 is compressed by forming the ridges 23 protruding toward the contact plane 22 on the other side surface as well as forming the 22, each ridge 23 is formed on each contact plane 22 of each coil portion 21. To cut the waste hair that has entered between the contact plane 22 and the ridge 23. In this case, the "other side surface" refers to the surface of the two surfaces of the coil portion 21 with respect to the compression direction, which is opposite to the surface on which the contact plane 22 is formed. Therefore, the ridges 23 formed on the other adjacent coil portions 21 project from each contact plane 22.

By the way, when the tweezers arm 11 of the tweezers main body 10 is in the open state, the coil spring 20 in the waste hair cutting 100 has the coil portion 21 of each coil portion 21 as shown in FIGS. 2 and 4A. Gap of uniform width is formed between them, and these gaps are sufficiently visible without being blocked by other parts. Here, when the waste hair to be removed is on the surface of the shin or in the nostril, if the coil spring 20 is directed toward the waste hair while visually or in a mirror, the waste hair can be removed from each coil portion 21. It easily gets into the gap between them.

On the other hand, if there is waste hair in the ear canal, the user cannot visually check it or reflect it in a mirror, and the gap between the coil portions 21 cannot be visually recognized. However, the coil spring 20 can be inserted into the ear canal as it is in the state shown in FIG. 1, and since a large number of gaps having an equal width are formed between the coil portions 21, for example, while rotating the coil spring 20. By inserting the hair, the waste hair can be inserted into the gap between the coil portions 21, and the sensitive ear canal can feel this.

When the waste hair gets into the gap between the coil portions 21, the tip portion 12 is loosely closed by sandwiching the pair of tweezers arms 11 facing each other with fingers, for example, as shown in FIG. 4 (b). In addition, as a first step, the coil portions 21 on both sides first grab the waste hair.

What is important here is that, for each coil portion 21, a contact plane 22 substantially orthogonal to the compression direction is formed on one side surface in the compression direction, and a protrusion protruding toward the contact plane 22 on the other side surface. Article 23 is formed. Then, as a second step, when the coil spring 20 is further compressed, each ridge 23 strongly abuts on each contact plane 22 of each coil portion 21, and these contact planes 22 and the ridge 23 The waste hair in between will be sheared, that is, cut.

In this case, when the coil spring 20 is closed, the entire outer surface of each coil portion 21 is continuous at short intervals (about the diameter of each coil portion 21) as shown in FIG. 4B. The compressed coil spring 20 comes into contact with the surface of the skin on which waste hair grows without causing pain. As a result, the waste hair is grasped by each of the contact planes 22 and the ridges 23, and then cut at a position close to the hairline. Therefore, it may be pulled out as in Patent Documents 1 and 2. It will be cut off at that position without any pain on the skin, and it will be removed with a smooth feeling.

Here, as the forming position of each ridge 23 with respect to each coil portion 21, the example shown in FIGS. 5A to 5C can be typically considered. The example shown in FIG. 5A is shown in FIGS. 2 and 3, but even if the tip of the ridge 23 is slightly displaced when the coil spring 20 is compressed, the contact plane is surely formed. It comes into contact with 22 and can sufficiently cut waste hair. In the example shown in FIG. 5B, the ridges 23 in each coil portion 21 are located on the outermost side of the coil spring 20, and in particular, the outer surface of the ridges 23 is shown in FIG. As shown in (b), if the contact plane 22 is set to be substantially orthogonal to the contact plane 22, the outer surface of each ridge 23 will be in close contact with the skin without any gap, and the smooth feeling can be improved. .. In the example shown in FIG. 5 (c), contrary to the example shown in FIG. 5 (b), each ridge 23 is formed at a position forming the inner surface of the coil spring 20. It is suitable for using the shaft 30.

As described above, both sides of the waste hair to be removed are firmly grasped by the contact plane 22 and the ridge 23 of each coil portion 21, and then sheared by both, and the entire waste hair cut 100 is moved. Even if it is not, the waste hair will be cut off from the skin.

Therefore, according to the waste hair cutting 100 according to the present invention, when the "coil spring" is compressed by the "tweezers", the waste hair can be firmly grasped, and even if it is a local waste hair cutting, " It is possible to cut waste hair with a smooth feeling while making full use of the advantages of "tweezers" and "coil spring".

In order to solve the above problems, the means adopted by the invention according to claim 2 is the tweezers type waste hair cutting 100 according to claim 1.
"By arranging the guide shaft 30 in the coil spring 20, the guide shaft 30 guides the movement of each coil portion 21 at the time of contraction and expansion."
Is.

In the waste hair cutting 100 according to claim 2, as shown in FIG. 6, the guide shaft 30 is arranged in the coil spring 20 used, but the length of the guide shaft 30 is contracted. The length of the coil spring 20 is sufficient, and the diameter or outer shape of the guide shaft 30 is sufficient so that it can come into contact with the inner surface of the coil spring 20. If the guide shaft 30 is arranged in the coil spring 20, the inner surface of each coil portion 21 is guided by the guide shaft 30 when the coil spring 20 is compressed and expanded by the tweezers main body 10, so that the guide shaft 30 is guided by the guide shaft 30. 30 ensures that each coil portion 21 does not shift in position with respect to the direction orthogonal to the axial direction of the guide shaft 30, and the contact between the contact plane 22 of each coil portion 21 and the tip of the tweezers 23 is stable. You can do it with.

Therefore, according to the waste hair cutting 100 according to claim 2, in addition to exhibiting the same function as that of claim 1, each coil portion 21 constituting the coil spring 20 does not shift in position. There is.

As described above, in the invention according to claim 1,
"By sandwiching a pair of tweezers arms 11 facing each other with fingers, the tweezers main body 10 that closes the tip portions 12 of these tweezers arms 11 and the tip portions 12 of each tweezers arm 11 are attached to each tip portion 12 A tweezers-type waste hair trimmer 100 composed of a coil spring 20 that is compressed when the arm is closed.
For each coil portion 21 constituting the coil spring 20, a contact plane 22 substantially orthogonal to the compression direction is formed on one side surface in the compression direction, and a protrusion protruding toward the contact plane 22 on the other side surface. When the coil spring 20 is compressed by forming the strip 23, each ridge 23 is brought into contact with each contact plane 22 of each coil portion 21, and between these contact planes 22 and the ridge 23. I tried to cut the waste hair that entered. "
There is a characteristic of its composition, so that when the coil spring 20 is compressed by the tweezers body 10, the waste hair can be firmly grasped, and even if it is a local waste hair cutting, the tweezers body 10 and It is possible to provide the waste tweezers 100 that can be performed with a smooth feeling while fully utilizing the advantages of the coil spring 10 by a simple structure.

Further, in the invention according to claim 2, the tweezers type waste hair cutting 100 according to claim 1 is used.

(B) is a cross-sectional view when the tip of the ridge 23 is on the outermost side of the contact plane 22, and (c) is a cross-sectional view when the tip of the ridge 23 is on the innermost side of the contact plane 22. It is a cross-sectional view of. It is sectional drawing which shows typically the Example using the guide shaft 30. The prior art is shown, (a) is a sectional view of the hair removal apparatus proposed in Patent Document 1, and (b) is a sectional view of the hair removal apparatus proposed in Patent Document 2.

Next, the invention according to each claim configured as described above will be described with respect to the waste hair cutting 100 according to the embodiment shown in the drawings. In FIG. 1A, the tweezers main body 10 and the coil spring 20 are shown. A front view of the waste hair cutting 100 configured by the above is shown, and FIG. 1 (b) shows a plan view of the waste hair cutting 100.

The tweezers main body 10 is formed by bending or connecting the base end portions (left side portion in the drawing) of a pair of tweezers arms 11 facing each other in the same manner as a general tweezers body 10, and is shown in the figure when no force is applied. As shown in No. 1, both tweezers arms 11 have an elastic force that can keep each outer end portion 12 of the tweezers arm 11 in an open state.

As shown in FIG. 1B, a spring fastening groove 13 is formed in the outer end portion 12 of each tweezers arm 11 in the present embodiment, and a coil described later is formed in the spring fastening groove 13. Coil portions 21 located at both outer ends of the spring 20 are locked, and both are fixed at the locked portions by means such as welding, if necessary. In addition, protrusions (cut ends of the coil spring 20 described later) and burrs (when welded) that may damage human skin may remain in the locking portion and the welded portion. Is removed by means such as polishing.

Further, the coil spring 20 constituting the waste hair cutting 100 is a compression spring, but as shown in FIG. 1, outside the pair of tweezers arms 11 constituting the tweezers main body 10 having a general tweezer shape. It is attached between the ends 12, and is compressed by sandwiching each tweezers arm 11 with a fingertip. As a result, the waste hair cutting 100 of the present embodiment is a manual tool that compresses the coil spring 20 at the tip by operating the tweezers main body 10.

The coil spring 20 has a length of about 7 mm to 10 mm in the uncompressed state shown in FIG. 1 (a), and the diameter of each continuous coil portion 21 is about 3 mm to 5 mm. It is designed so that it can be inserted into the nostrils and ear canals. That is, the coil spring 20 of the waste hair cutting 100 can be inserted into the nostril or ear canal as it is in the state shown in FIG. Then, when the outer end portions 12 of both tweezers arms 11 are not closed, the coil spring 20 is opened to form a gap between the coil portions 21 so that waste hair can enter, as shown in FIG. When each outer end portion 12 is closed, as shown in FIG. 3, the coil portions 21 are compressed so that there is no gap between them. In the present embodiment, the number of coil portions 21 (referring to one turn of the coil spring 20) is about 7 to 12 for the coil spring 20 having the above length.

Further, as shown in FIGS. 2 to 4, each coil portion 21 of the coil spring 20 constituting the waste hair cutting 100 has a contact plane substantially orthogonal to the compression direction on one side surface of the compression direction. When the coil spring 20 is compressed by forming the ridges 23 protruding toward the contact plane 22 on the other side surface as well as forming the 22, each ridge 23 is formed on each contact plane 22 of each coil portion 21. To cut the waste hair that has entered between the contact plane 22 and the ridge 23.

By the way, when the tweezers arm 11 of the tweezers main body 10 is in the open state, the coil spring 20 in the waste hair cutting 100 has the coil portion 21 of each coil portion 21 as shown in FIGS. 2 and 4A. Gap of uniform width is formed between them, and these gaps are sufficiently visible without being blocked by other parts. Here, when the waste hair to be removed is on the surface of the shin or in the nostril, if the coil spring 20 is directed toward the waste hair while visually or in a mirror, the waste hair can be removed from each coil portion 21. It can be put in the gap between them.

On the other hand, if there is waste hair in the ear canal, the user cannot visually check it or reflect it in a mirror, and the gap between the coil portions 21 cannot be visually recognized. However, the coil spring 20 can be inserted into the ear canal as it is in the state shown in FIG. 1, and since a large number of gaps having an equal width are formed between the coil portions 21, for example, while rotating the coil spring 20. By inserting the waste hair, it is possible to insert the waste hair into the gap between the coil portions 21.

When the waste hair gets into the gap between the coil portions 21, the tip portion 12 is loosely closed by sandwiching the pair of tweezers arms 11 facing each other with fingers, for example, as shown in FIG. 4 (b). In addition, as a first step, the coil portions 21 on both sides first grab the waste hair.

What is important for the coil spring 20 in this embodiment is, as shown in each (b) of FIGS. 2 and 3, for each coil portion 21 constituting the coil spring 20, one of the compression directions thereof. A contact plane 22 orthogonal to the compression direction is formed on the side surface, and a ridge 23 protruding toward the contact plane 22 is formed on the other side surface. The reason is that when the coil spring 20 attached between the tip portions 12 of each tweezers arm 11 is compressed by operating the tweezers main body 10 constituting the waste hair cutting 100, each coil portion 21 This is because when the ridges 23 come into contact with the contact plane 22, the waste hair between the contact planes 22 and the ridges 23 is sheared, that is, cut.

Therefore, it is most effective to make the shape of the tip of each ridge 23 (the part that is the mountain of the ridge) like the "tip of the blade" as shown in FIG. is there. Further, as the forming position of each of the ridges 23, as shown in FIGS. 5A to 5C, the mountain portion of the ridges 23 is centered with respect to the contact plane 22. The case where it is located (a), the case where it is located at the outermost end (b), and the case where it is located at the innermost end (c) can be considered.

As a typical position of each ridge 23, in the example shown in FIG. 5 (a), those shown in FIGS. 2 and 3, but when the coil spring 20 is compressed, the tip of the ridge 23 is Even if it is slightly displaced, it surely abuts on the contact flat surface 22, and waste hair cutting can be sufficiently performed. In the example shown in FIG. 5B, the ridges 23 in each coil portion 21 are located on the outermost side of the coil spring 20, and in particular, the outer surface of the ridges 23 is shown in FIG. As shown in (b), if the contact plane 22 is set to be substantially orthogonal to the contact plane 22, the outer surface of each ridge 23 will be in close contact with the skin without any gap, and the smooth feeling can be improved. .. In the example shown in FIG. 5 (c), contrary to the example shown in FIG. 5 (b), each ridge 23 is formed at a position forming the inner surface of the coil spring 20. It is suitable for using the shaft 30.

FIG. 6 illustrates the waste hair cutting 100 according to claim 2. In this example, the guide shaft 30 is arranged in the coil spring 20 used, and the length of the guide shaft 30 is long. The length of the contracted coil spring 20 is sufficient, and the diameter or outer shape of the guide shaft 30 is sufficient so that it can come into contact with the inner surface of the coil spring 20. If the guide shaft 30 is arranged in the coil spring 20, the inner surface of each coil portion 21 is guided by the guide shaft 30 when the coil spring 20 is compressed and expanded by the tweezers main body 10, so that the guide shaft 30 is guided by the guide shaft 30. 30 ensures that each coil portion 21 does not shift in position with respect to the direction orthogonal to the axial direction of the guide shaft 30, and the contact between the contact plane 22 of each coil portion 21 and the tip of the tweezers 23 is stable. You can do it with.
