Description

  The present invention relates to the structure of the handle portion.

  The thing that a person operates with a hand includes a handle for holding the object with a palm and a fingertip, a handle, and other handle parts. For the purpose of preventing slipping, a plurality of anti-slip holes or a composite product incorporating rubber or other resin having a high friction coefficient has been proposed for these handle parts (see, for example, Patent Document 1). ).

  However, when the handle portion is provided with a non-slip hole, the sliding effect is limited only at the location where the anti-slip hole hits the palm when the handle portion is gripped, and the compression is repeated only at that location. . For this reason, the keratin on the skin surface becomes hard and thick for a long time, and there is a possibility that the portion becomes octopus in some cases.

  When a resin having a large coefficient of friction is incorporated in the handle portion to prevent slipping, the handle portion becomes a composite product, and molding is troublesome.

  In any case, an anti-slip effect cannot be obtained unless the portion of the handle portion where the anti-slip hole is formed or the portion where the resin having a large friction coefficient is incorporated is conscious. For this reason, in order to obtain the effect, the user needs to be aware of the handle portion. Therefore, workability is reduced accordingly.

  Also, depending on the object, it may require delicate work such as gripping an article with a handle part very lightly or working with a dominant index book. If the surface shape does not match well, it may be possible to drop the object during work.

For delicate work, use a toothbrush, shave leather, a mascara brush for makeup on the eyes and a brush for liquid eyeliner, eyebrow pencil for drawing eyebrows, and lipstick. Examples include lip brushes, powder brushes and fan brushes used to apply powders and liquids for facial makeup.
Japanese Utility Model Publication No. 7-39569

  The present invention has been made in view of such circumstances, and the problem to be solved is that the handle portion is firmly held even when the handle portion is held very lightly or is held with a dominant index book. Another object of the present invention is to provide a handle structure that fits the fingertip.

  Therefore, the present invention employs the following means in order to solve the above problems.

That is, the present invention is a structure of a handle part integrated with an action part of an article having a handle part, and the handle part has a three-dimensional concavo-convex part on an outer peripheral surface thereof. The original concavo-convex part has a plurality of unit surfaces, a boundary ridge line defining the unit surface, and an intersection part formed by the boundary ridge lines intersecting, and the boundary ridge line and the intersection part are the unit surfaces. The unit surface is positioned relatively outward from the axis of the handle portion, and the unit surface is a concave curved surface shape that is smoothly recessed between the opposing intersections, and is adjacent in the circumferential direction of the handle portion. It is characterized by being relatively displaced in the axial direction of the handle portion in comparison with the surface.

  The three-dimensional concavo-convex portion means three-dimensional concavo-convex not planarly concavo-convex. Moreover, the unit surface which comprises a three-dimensional uneven | corrugated | grooved part says that the cross section and vertical cross section appear as a dent of a curve or a U thru | or V shape.

  Therefore, according to the structure of the handle portion of the present invention, since the three-dimensional uneven portion is formed on the outer surface of the handle portion, it is picked up by the hand compared with the handle portion without the three-dimensional uneven portion. Occasionally, the degree of close contact between the handle surface and the palm or fingertip is high. For this reason, when the user grips the handle portion or holds it with the dominant finger, the fit feeling transmitted from the handle portion is excellent. Therefore, it is difficult for the handle portion to be separated from the palm or fingertip (slippery).

  In addition, by forming a three-dimensional uneven part almost all over the outer surface of the handle part, it is difficult for the palm and fingertips to separate from the handle part wherever they are held. You can dispel the awareness that you must have a specific part of the part. Therefore, workability can be improved.

  It is preferable that the radius of curvature of the recess of the unit surface is the radius of curvature of a finger ball having an average size.

  You may make it the said action part and the said handle part integrate with a screwing means.

  When the article having the handle portion is temporarily not used, the handle portion is hooked on the belt of the user's pants, the upper edge of the waist portion, an appropriate string or other lockable portion or place. It is convenient if the part is formed.

  According to the handle portion of the present invention, the fit is high, and the handle portion is difficult to separate from the palm and fingertips, so a delicate feel is transmitted to the user through the handle portion when performing delicate work. come. Therefore, even if the object using the article is a delicate person's skin or the like, the operation can be performed with an optimal force applied to the person.

  In addition, it is hard to fall even if the handle is lightly gripped. In addition, by forming a three-dimensional uneven part almost all over the outer surface of the handle part, it is difficult for the palm and fingertips to separate from the handle part wherever they are held. You can dispel the awareness that you must have a specific part of the part. Therefore, workability can be improved.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of a structure of a handle portion according to the invention will be described with reference to the drawings.

A first embodiment will be described with reference to FIGS.
The first embodiment discloses a case where the structure of the handle portion according to the present invention is applied to a toothbrush.

  The toothbrush 1 is made of, for example, a synthetic resin or wood, and includes a flocked portion 20 that is an action portion, and a handle portion 31 that is formed integrally with the flocked portion 20 and is coaxial and has a rod shape.

  Brush hairs 21 are planted in a predetermined range on the planted part 20, and toothpaste is applied to this part.

The handle portion 31 has a three-dimensional concavo-convex portion 40 in almost the entire outer peripheral surface except for both ends thereof.
Further, when the user cannot temporarily hold the toothbrush 1 at the tip of the handle portion 31, that is, the end located on the opposite side in the axial direction of the toothbrush 1 with respect to the flocked portion 20, for example, before and after brushing teeth. When the face is washed or gargled and both hands cannot be used, a locking portion 32 is formed for hanging on a string provided at an appropriate position of the washstand (see FIG. 12). . The locking portion 32 is shaped like a question mark “?” In the longitudinal section. Note that the locking portion 32 may not be provided.

  As can be seen from FIGS. 1, 2, 5, 10, etc., the three-dimensional concavo-convex portion 40 is composed of unit surfaces 50, boundary ridge lines 60 that define a large number of unit surfaces 50, and boundary ridge lines intersect each other. It is a three-dimensional concavo-convex portion having a possible intersection point portion 70 as a constituent element. The crossing point portion 70 is a portion where the boundary ridge lines 60 cross each other linearly. The boundary ridge line 60 appears to meander and extend in the axial (longitudinal) direction of the handle portion 31.

  In short, the three-dimensional concavo-convex portion 40 is formed by combining a large number of substantially quadrangular unit surfaces 50 connecting the apexes a, b, c, and d as shown in FIG. In this embodiment, the quadrangular shape of the unit surface 50 has a long rhombus shape in the axial direction as shown in FIGS. The unit surface 50 is adjacent to the other unit surface 50 via the boundary ridge line 60.

  The unit surface 50 is a surface defined by certain sections ab, bc, cd, and da that constitute the boundary ridge line 60. The boundary ridge lines drawn in the constant sections ab, bc, cd, and da, which are a part of the boundary ridge lines 60, are referred to as ridge lines of the unit surface in this specification, and are denoted by reference numerals 60ab, 60bc, 60cd, and 60da (see FIG. 9).

  Of the vertices a, b, c, and d of the unit surface 50, the vertex a when the flocked portion 20 is directed upward in the axial direction of the handle portion 31 is referred to as the upper vertex a, and the vertex c is the lower vertex c. In this case, the vertex b located on the left in the circumferential direction is called the left vertex b, and the vertex d located on the right is called the right vertex d.

  The upper vertex a and the lower vertex c are located on a virtual circle C1 having the same diameter (see FIG. 10). The left vertex b and the right vertex d are located on another virtual circle C2 having the same diameter (see FIG. 11).

  The radius r1 of the virtual circle C1 and the radius r2 of the virtual circle C2 are the radius of curvature of the recess of the unit surface 50. Preferably, the radius r1 of the virtual circle C1 matches the curvature radius in the longitudinal direction of the finger ball (the abdominal surface of the finger end) of the average size of the user (for example, Japanese), and the radius r2 of the virtual circle C2 is Similarly, it is preferable to match the radius of curvature in the width direction of the finger ball.

  In other words, the unit surface 50 is smoothly recessed with the central point at the bottom between the opposing vertices a-c (see FIG. 10), and is smooth with the central point at the bottom between the opposing vertices b-d. (See FIG. 11). In the unit surface 50, the point located at the center between the vertices a-c and the point located at the center between the vertices b-d are the same, and are indicated by the symbol m and hereinafter referred to as the center point.

Each of the vertices a to d is curved rather than a point even if it is called a vertex. Therefore, the ridgelines 60ab, 60bc, 60cd, and 60da of the unit surface constituting the unit surface 50, and the boundary ridgeline 6
It can be said that 0 is a line composed of a curve and a straight line.

  Further, the ridge lines 60ab, 60bc, 60cd, 60da and the vertices a, b, c, d of the unit surface 50 are surrounded by portions that become actual surfaces in the unit surface 50, in other words, the ridge lines 60ab, 60bc, 60cd, 60da. Is located relatively outward from the axis C (see FIGS. 1 and 8) of the handle portion 31 relative to the portion (hereinafter referred to as a real surface portion) 50 ′ (see FIGS. 9 to 11). )

  Furthermore, the unit surface 50 is relatively displaced by a length that is one-half of the length of the diagonal line ac in the axial direction of the unit surface 50 and the handle portion 31 adjacent to each other in the circumferential direction of the handle portion 31 ( 1 and 5).

  On the other hand, the ridge lines 60ab, 60bc, 60cd, and 60da of the unit surface protrude outward most at the ends of the upper vertex a and the lower vertex c, and the axial center C as it goes to the middle of the ridge lines 60ab, 60bc, 60cd, and 60da. The distance from is reduced (see FIGS. 8 to 11). That is, the upper vertex a and the lower vertex c overlap when the unit surface 50 is projected in the axial direction, and the left vertex b and the right vertex d overlap when projected in the width direction.

  The diagonal line ac intersects with the diagonal line bd and is positioned outside the axis C with respect to the diagonal line bd. Because of this positional relationship, it can be said that the quadrilateral abcd is a surface that is not on the same plane, that is, a curved or bent surface.

  The rhombus dimensions as the unit surface 50 are the diagonal lines in the circumferential direction (hereinafter referred to as the circumferential diagonal line) bd when viewed in a plane, W (see FIG. 11), and the diagonal lines in the axial direction when viewed in the same plane. (Hereinafter, the diagonal in the axial direction) When the length of ac is L (see FIG. 10), W and L are respectively the maximum width of the unit surface 50 in the circumferential direction of the toothbrush 1 and the unit surface 50 when the unit surface 50 is viewed in a plane. This is the maximum length of the toothbrush 1 in the axial direction.

  The length L of the axial diagonal line ac is different from the actual length L ′ (see FIG. 10) in the longitudinal section of the unit surface 50 along the axial diagonal line ac, and the length W of the circumferential diagonal line bd. It is clear from the above description that the actual length W ′ (see FIG. 11) in the cross section of the unit surface 50 along the circumferential diagonal bd is different.

  Therefore, as shown in FIGS. 8, 10 and 11, the unit surface 50 appears as a curved or U-shaped recess.

  Therefore, the cross section of the handle portion 31 on which the three-dimensional concavo-convex portion 40 having a large number of unit surfaces 50 is formed is from a concave curved side that is recessed toward the axis C as shown in FIGS. And each apex of the rectangular cross section is somewhat rounded.

The specific dimensions of the unit surface are as follows.
Diagonal length W in the circumferential direction of the unit surface: 10 mm to 12 mm
Diagonal length L in the axial direction of the unit surface: 20 mm to 22 mm
Angle of vertex a: 60 °
Angle of vertex b: 120 °
Angle of vertex c: 60 °
Angle of vertex d: 120 °
Length of ridgeline 60ab / 60bc / 60cd / 60da of unit surface: 10 to 12 mm
Radius r1 of virtual circle C1: 19 mm to 24 mm
Radius r2 of virtual circle C1: 19 mm to 24 mm

  A large number of unit surfaces 50 constituting such a three-dimensional concavo-convex portion 40 are not only concavely curved, each of which is smoothly recessed, but the three-dimensional concavo-convex portion 40 is used by a user (for example, Because the radius of curvature r2 of the virtual circle C2 is also matched with the radius of curvature of the fingerball in the width direction, and the radius r2 of the virtual circle C2 is also matched with the radius of curvature of the fingerball in the longitudinal direction. , The feel when the handle portion 31 is held in hand is good and familiar.

  Accordingly, when the user grips the handle portion 31 having the three-dimensional uneven portion 40 (see FIG. 3) or holds it with a dominant finger (see FIG. 4), the handle portion 31 is transmitted from the handle portion 31. The fit is excellent.

  Since the handle portion 31 is excellent in fit as described above, the handle portion 31 when the handle portion 31 is picked up by the hand is compared with a handle portion having no three-dimensional uneven portion 40 in the handle portion. The degree of close contact between the surface of the palm and the palm (dominant finger) is increased, and the handle portion 31 is less likely to slip away from the palm or finger, making it difficult to separate. Therefore, even if the handle portion 31 is lightly gripped, it is difficult to fall.

  Further, a subtle touch is transmitted to the user through the handle portion 31. Therefore, even when the brush hits sensitive gingiva, it is possible to apply an optimum and delicate force that meets the person.

  Furthermore, since many unit surfaces 50 are formed in almost the entire outer peripheral surface of the handle portion 31, there is an anti-slip effect wherever the handle portion 31 is held. As a result, the palm and fingertips are unlikely to be separated from the handle portion wherever they are held, so that it is possible to dispel the awareness that a specific portion of the handle portion must be held in order to obtain the effect. Therefore, the usability is improved and the workability is improved as compared with the conventional handle portion in which the anti-slip effect cannot be obtained unless the handle portion is a specific portion.

A second embodiment will be described with reference to FIG.
In Example 2, the structure of the handle part of the present invention is applied to the leather handle part for shaving, and the handle part is the same as in Example 1. Therefore, the same parts are denoted by the same reference numerals and description thereof is omitted.

  The shaving leather 1A includes a leather portion 20A as an action portion and a handle portion 31A formed integrally with the leather portion 20A.

  Even in the second embodiment, as in the first embodiment, it can be said that the fit feeling when the handle portion 31A is gripped by the three-dimensional uneven portion 40 or held with the dominant finger is extremely excellent. Therefore, even when the user grasps the handle portion 31A lightly or works with the dominant index book, the handle portion 31A is unlikely to be separated from the palm.

  For this reason, when performing shaving using a leather to shave the beard, adjustment can be made with a subtle force. Therefore, it is possible to make it difficult to fall even if the handle portion is lightly grasped, as well as suitable shaving is possible.

Embodiment 3 will be described with reference to FIG.
In Example 3, the structure of the handle portion of the present invention is applied to eyelashes to make the eyelashes darker and longer, and mascara, which is one of eye makeup cosmetics used for the purpose of strengthening the impression of the eyelashes, is used. This is applied to the handle portion of the mascara brush applied to the skin.
The handle portion is the same as in the first and second embodiments. Therefore, the same parts are denoted by the same reference numerals and description thereof is omitted.

  The mascara brush 1B includes a brush portion 20B that is an action portion, and a handle portion 31B that is coaxially formed integrally with the brush portion 20B.

  The brush portion 20B has a large number of short brushes 21B in a predetermined region of the rod-shaped tip portion.

  The handle portion 31B is about four times as large as the brush portion 20B in diameter and slightly shorter than the brush portion 20B, and is roughly the length of about three human fingers. And the three-dimensional uneven | corrugated | grooved part 40 is formed in the surface similarly to Example 1 and Example 2. FIG.

  When the mascara is applied to the eyelashes with the mascara brush 1B, the handle portion 31B is held with a dominant finger, and the brush portion 20B is put into the mascara container 100 containing the mascara through the opening 100a. As a result, mascara is attached to the short brush 21B of the brush portion 20B, so the mascara brush 1B is taken out from the mascara container 100 and the mascara attached to the short brush 21B is applied to the eyelashes.

  Even in the third embodiment, since the handle portion 31B is formed with the three-dimensional uneven portion 40, the sense that the handle portion 31B fits the finger when holding it with a dominant finger is extremely excellent. It can be said. Therefore, the user not only feels easy to handle the mascara brush 1B, but also the handle portion 31B is difficult to separate from the finger.

  For this reason, when applying mascara to the eyelashes with the mascara brush 1B, it is possible to make adjustments with a subtle force, so that suitable mascara can be applied.

  In addition, as an application example of the third embodiment, it is a tool for edging the eyeline to make the white eye and the shape of the eye clear and can be applied to the handle portion of a liquid eyeliner similar in shape to a mascara brush. Of course.

  The only difference between the liquid eyeliner and the mascara brush is that the brush portion of the mascara brush is a brush portion for applying a liquid-like pigment (see FIG. 15). In FIG. 15, the brush portion is denoted by reference numeral 21 b, and the same parts as those of the mascara brush are denoted by the same reference numerals as those of the mascara brush, and description thereof is omitted.

Embodiment 4 will be described with reference to FIG.
In Example 4, the structure of the handle portion of the present invention is applied to a makeup cosmetic device having a rod-shaped handle portion. Makeup cosmetic tools with a stick-shaped pattern include eyebrow pencils for drawing eyebrows, powder brushes with softening brushes for filling the skin with irregularities on the skin without gaps, and gradations. Fan brushes for lipstick, lip brushes for applying lipstick, and the like.

FIG. 16 illustrates an eyebrow pencil 1C.
The eyebrow pencil 1C includes a lead tip 20C as an action portion and a handle 31C as a handle portion. The handle structure of the present invention is applied to the handle 31C. Therefore, the same parts as those in the first to third embodiments are denoted by the same reference numerals and description thereof is omitted.

Even in Example 4, since the three-dimensional uneven portion 40 is formed on the handle 31C, it can be said that the sense that the handle 31C fits the finger when holding it with a dominant finger is extremely excellent. Therefore, the user not only feels that the eyebrow pencil 1C is easy to handle, but also the handle 31C is difficult to separate from the finger.

  For this reason, since adjustment by a delicate force condition can be performed when drawing eyebrows with the eyebrow pencil 1C, it is possible to draw a suitable eyebrow.

  In FIG. 16, eyebrow pencils are illustrated as makeup tools having a stick-shaped handle portion. However, the powder brush, fan brush, and lip brush, which are similar makeup tools having a stick-shaped handle portion, are used. In that case, instead of the tip 20c of the eyebrow pencil 1C, only the brush brush is attached to the tip of the handle 31C, and the makeup can be made while adjusting the delicate force. The same can be said.

Embodiment 5 will be described with reference to FIG.
In Example 5, the structure of the handle portion of the present invention is applied to the handle portion of a double-blade razor.

  The double-blade razor 1D includes a blade portion 20D that is an action portion and a handle 31D that is a handle portion. The handle structure of the present invention is applied to the handle 31D. Therefore, the same parts as those in the first to fourth embodiments are denoted by the same reference numerals and description thereof is omitted.

  Even in Example 5, since the pattern 31D has the three-dimensional uneven portion 40, it can be said that the feeling that the pattern 31D fits the finger when holding it with a dominant finger is extremely excellent. Thus, the user not only feels that the double-blade razor 1D is easy to handle, but also the handle 31D is difficult to separate from the finger.

Example 6 will be described with reference to FIG.
In the sixth embodiment, the structure of the handle portion of the present invention is applied to the handle portion of the curl iron.

FIG. 18 illustrates a curling iron 1E.
The curling iron 1E includes a trowel portion 20E as an action portion and a handle 31E as a handle portion. The handle structure of the present invention is applied to the handle 31E. Therefore, the same parts as those in the first to fifth embodiments are denoted by the same reference numerals and description thereof is omitted.

  Even in Example 6, since the three-dimensional uneven portion 40 is formed on the handle 31E, it can be said that the sense that the handle 31E fits the finger when holding it with a dominant finger is extremely excellent. Therefore, the user not only feels easy to handle when ironing the hair with the curling iron 1E, but also the handle 31E is difficult to separate from the finger.

  The present invention is not limited only to the above-described embodiments, and it goes without saying that various changes can be made without departing from the scope of the present invention. In addition to the above embodiment, it is also conceivable to apply the present invention to the handle portion of the hair brush. In short, the present invention can be applied to a handle portion if there is a handle portion in an article that requires delicate work.
