Description

  The present invention relates to tweezers used to remove wasted hair, thorns, and the like.

  As shown in FIG. 5, a conventional general tweezers 1 used for removing waste hair, thorns and the like includes a pair of hand-held portions 2 separated from each other at the front end side and integrated with each other at the rear end side. And a pinching portion 3 provided at the tip of the portion 2, and the user operates the pair of handheld portions 2 with their fingers to close the tip side (hereinafter referred to as “closing operation”), thereby pinching the pinching portion 3. In this case, the object of hair removal such as wasted hair or thorns (hereinafter referred to as “the object of hair removal”) is sandwiched.

  As shown in FIG. 5, in the conventional tweezers 1, the tip portion of the member constituting the hand-held portion 2 is bent inward, and the sandwiched portion 3 is configured by this bent portion. And the contact part 4 which mutually contact | abuts is comprised by the front end surface of the clamping part 3 which protrudes inside when a pair of hand-held part 2 is closed, and the contact part 4 exhibits a linear form. It has become a thing.

  Therefore, in order to remove the object to be tipped, the tip of the nipping part is used in the direction of tweezers so that the linear contact portion is orthogonal to the direction in which the object to be tweeled is pulled out (hereinafter referred to as “pulling direction”). However, the conventional tweezers are inferior in convenience with a low degree of freedom with a limited portion to be used. In addition, since the direction of tweezers is limited, the degree of freedom of the direction of the hand that inevitably operates the hand-held portion is inevitably low, and conventional tweezers are also inferior in this respect.

  By the way, tweezers have a flat shape like tweezers for stamps, and when the pair of hand-held portions are operated to be closed, the surfaces facing each other (hereinafter referred to as “inner surfaces”) of the respective gripping portions come into contact with each other. If it does so, a tweezers target object can be pinched also by parts other than the tip of a pinching part. In other words, by making the pinch portion flat, more portions of the pinch portion can be used, and it becomes possible to change the direction of tweezers or change the direction of the hands, improving convenience as tweezers. be able to.

  However, if the flat sandwiching portions are brought into contact with each other, it is difficult to make the entire inner surface of the sandwiching portion uniformly contact with each other, and depending on the portion of the sandwiching portion where the object to be removed is sandwiched, the object to be removed is reliably sandwiched. There is a risk that it will not be possible. Further, since a wide surface such as the entire inner surface of the sandwiching portion is brought into contact, the force for contacting each sandwiching portion is dispersed, and there is a possibility that the object to be removed cannot be strongly sandwiched.

  The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a tweezer that has a high degree of freedom in a part that sandwiches a tweezer object and that can securely tuck the tweezer object reliably. .

The main measures taken by the present invention to solve the above problems are as follows:
“A pair of hand-held parts separated from each other at the front end side and integrated with each other at the rear end side,
A clip portion provided at the tip of each hand-held portion;
A recess provided on the surface of each of the sandwiching portions facing each other;
The tweezers are configured by respective outer peripheral edge portions of the respective concave portions, and are provided with contact portions that contact each other when the pair of hand-held portions are operated to close.
It is.

  In the tweezers having the above-described configuration, since the pinching portion has a flat shape in which a concave portion is provided on the inner surface, the object to be tipped can be pinched by a portion other than the tip of the pinching portion, such as both sides of the pinching portion. . Therefore, the direction of the tweezers can be changed and the tweezer object can be pinched by an appropriate part of the pinching portion, and the convenience as tweezers can be improved.

  Further, the portion to which the force to be sandwiched between the tweezers is applied is a contact portion provided on the inner surface of each sandwich portion, but a recess is provided on the inner surface of each sandwich portion, and the contact portion is provided on the inner surface of the recess. It is comprised by the outer periphery part. In other words, the contact portion is not the entire inner surface of the sandwiching portion but an annular surface that is hollowed out by the recess, and the entire area of the surface of the contact portion is compared to the entire inner surface of the sandwiching portion. It is getting smaller. For this reason, when the hand-held portion is operated to close, the entire surface of each contact portion is in close contact with each other and contacted with a strong force, as compared with a mode in which the entire inner surface of the sandwiching portion is contacted. Therefore, according to the tweezers having such an abutting portion, the tweezers object can be pinched reliably and with a strong force.

In the means described above,
“The clip portion includes a bulging portion that bulges in the width direction from the tip of the hand-held portion.”
Is preferable.

  In the tweezers having the above configuration, the nipping portion has a bulging portion that bulges in the width direction from the tip of the hand-held portion. It can be used satisfactorily as a part for sandwiching an object. Therefore, according to the tweezers of the above configuration, the convenience as tweezers can be further improved.

  In addition, the pinching part can be clearly distinguished from the hand-held part by the bulging part, and the pinching part can be easily recognized. You can also.

In the means described above,
"The tweezers are formed in a circular shape or an oval shape.
Is preferable.

  Here, the oval includes a geometrical ellipse, a shape having a semicircle on both sides of a square, and the like, and indicates a wide range of shapes in which a circle is elongated.

  In the tweezers having the above-described configuration, since the sandwiching portion is circular or oval, the tweezers can be used by being inclined at a free angle with respect to the pulling direction within a range in which the object to be removed can be sandwiched by the sandwiching portion. . Therefore, according to the tweezers of the above configuration, the convenience as tweezers can be further improved.

  Moreover, since the sandwiched portion has a shape with no corners such as a circle or an oval, the touch when the sandwiched portion is applied to the skin is good. Therefore, tweezers that can be used comfortably can be realized.

  As described above, according to the present invention, it is possible to provide a tweezer that has a high degree of freedom in a portion that sandwiches the tweezer object and that can securely and strongly pinch the tweezer object.

It is explanatory drawing which shows the use condition of the tweezers shown in FIG. It is explanatory drawing which shows an example of the formation method of a recessed part. It is a principal part top view which shows the various forms of a clamping part. It is a perspective view which shows the conventional tweezers.

  FIG. 1 shows an example of tweezers according to the present invention.

  The tweezer 100 includes a pair of hand-held portions 10 that are separated from each other on the front end side and integrated with each other on the rear end side. Here, in this example, each of the pair of handheld portions 10 is configured by an individual member, and each handheld portion 10 is connected to the rear end side by joining the rear end portion of each handheld portion 10 by brazing or the like. It is united with. In addition, the pair of handle portions 10 closes at the tip end when operated with a finger, but when the force for closing is weakened, the tip ends open by the elastic force of the integrated handle portion 10 itself at the rear end portion. Return to. It should be noted that the pair of hand-held portions 10 is not limited to being configured by individual members as in the present example, and a pair of hand-held portions 10 in which the rear end side is integrated by a bent portion is configured by bending a single member. You may make it do.

  A flat sandwiching portion 20 is provided at the tip of each handle portion 10. Here, in this example, the hand-held portion 10 and the sandwiching portion 20 are integrally formed of the same member.

  A concave portion 21 is provided on the inner surface of each pinching portion 20, and an outer peripheral edge portion of the concave portion 21 constitutes an abutting portion 22 that abuts with each other when the hand-held portion 10 is closed. Here, in this example, the concave portion 21 has a shape in which the outline of the sandwiching portion 20 is reduced, and the contact portion 22 projects annularly around the concave portion 21 with a predetermined width on the inner surface of the sandwiching portion 20. ing.

  Thus, in the tweezers in which the contact portion 22 is provided around the recess 21 on the inner surface of the sandwiching portion 20, when the hand-held portion 10 is closed, the recess 21 is released as shown in FIG. The contact portion 22 is uniformly intimate throughout. In addition, the area of the entire surface of the contact portion 22 around the recess 21 is smaller than the entire inner surface of the sandwiching portion 20 by the amount hollowed out by the recess 21. Therefore, compared with the aspect which the whole inner surface of the flat clamping part 20 contact | abuts, the contact part 22 can be made to contact | abut with a strong force mutually with the force of the same closing operation. For this reason, according to the tweezer 100 of this example, the tweezers object can be pinched favorably and strongly.

  In addition, the recessed part 21 is specifically a shallow thing about 0.1-0.5 mm in depth, and even if the recessed part 21 is provided, sufficient intensity | strength of the clamping part 20 is ensured. Further, the width of the annular contact portion 22 projecting around the recess 21 is set to about 0,5 to 1 mm so that the object to be removed can be pinched accurately without being cut.

  By the way, although the shape of the pinching portion 30 can be set as appropriate, in this example, the pinching portion 20 is formed in a form including a bulging portion 23 bulging in the width direction from the tip of the hand-held portion 10. ing. Specifically, a boundary portion between the handle portion 10 and the sandwiching portion 20 is a constricted portion 30 that is narrow in a curved shape. In the sandwiching portion 20, the distal end side of the narrowest portion of the constricted portion 30 is formed. The portion is a bulging portion 23.

  Although the boundary between the handheld portion 10 and the sandwiched portion 20 is not necessarily clarified, by providing the constricted portion 30, the rear end side of the handheld portion 10 rather than the minimum width portion of the constricted portion 30, The front end side can be grasped as the sandwiching portion 20, and the boundary between the hand-held portion 10 and the sandwiching portion 20 can be clarified. In this way, by making the pinching portion 20 easy to understand with respect to the handheld portion 10 in appearance, when the pinching target object is pinched by the pinching portion 20, the pinching portion 20 is accurately positioned with respect to the pinning target object. Therefore, the tweezer 100 is easy to use.

  Further, since the sandwiching portion 20 is circular, as shown in FIG. 3A, the tweezer 100 is erected and is pulled in the pulling direction (arrow n) by sandwiching the tweezers k with the tip portion of the sandwiching portion 20. In addition, as shown in FIG. 3B, the tweezers 100 are freely tilted until the tweezers 100 lie sideways, and the tweezers k is sandwiched between the desired portions of the nipping portions 20 in the pulling direction (arrow n). Can be pulled. Thereby, the tweezers 100 of this example are the tweezers 100 with high convenience.

  In addition, not only making the pinching part 20 circular, but also if it is oval, the tweezers 100 can be inclined and used at a free angle.

  Further, since the sandwiching portion 20 has a bulging portion 23 on the handle portion 10 side, as shown in FIG. 3 (c), the tweezer 100 is perpendicular to the pulling direction (arrow n). By tilting as described above, the tweezers k can be pinched and pulled by the bulging portion 23 of the pinching portion 20. Thereby, the tweezers 100 of this example are tweezers 100 in which convenience is further enhanced.

  In this way, in the tweezers 100 in which the pinching portion 20 is bulged from the tip of the hand-held portion 10 as a circular shape or an oval shape, the pinching portion 20 has a shape with no corners. You can feel better when you touch. In addition, since the boundary portion between the handheld portion 10 and the sandwiching portion 30 is a constricted portion 30 that is narrow in a curved shape, the constricted portion 30 may be skinned when used with the tweezers 100 lying sideways with respect to the removing direction. To fit. In particular, in this example, the neck portion 30 has a curved shape that curves more gently than an arc, and the boundary portion between the handheld portion 10 and the sandwiching portion 20 can be more comfortably fitted to the skin.

  Next, an example of the formation method of the recessed part 21 is demonstrated using FIG. In the following, a method for forming the recess 21 in the tweezer 100 in which at least the pinch portion 20 is made of a metal material such as stainless steel will be described. However, in the case of the tweezer 100 in which the pinch portion 20 or the whole is made of resin as a raw material. The recess 21 may be formed at the same time when the member having the sandwiching portion 20 or the entire member is molded by the mold.

  First, as shown to Fig.4 (a), the metal mold | die 40 of the form corresponding to the shape of the recessed part 21 is arrange | positioned between the clamping parts 20 which oppose. Next, each pinching portion 20 is pressed (pressed) from the outside (see the white arrow), and the inner surface of the pinching portion 20 is plastically deformed as shown in FIG. 4B. Then, as shown in FIG. 4C, a recess 21 having a desired shape corresponding to the mold 40 is formed on the inner surface of each sandwiched portion 20. As described above, the concave portions 21 are simultaneously formed by the single mold 40 in each of the pair of sandwiching portions 20 facing each other, so that the accurate concave portions 21 that match each other on the inner surfaces of the pair of sandwiching portions 20, and An accurate contact portion 22 on the outer periphery of the recess 21 can be formed.

  In addition, when the recessed part 21 is formed by the plastic deformation of the metal material as described above, the protruding part 24 may be formed on the outer surface of the sandwiching part 20 as shown in FIG. Such a protrusion 24 may be left as it is, but if it is better not to have the protrusion 24 for reasons of appearance, the protrusion 24 may be removed by polishing or the like.

  Moreover, it is not restricted to forming the recessed part 21 simultaneously in each of a pair of clamping part 20 which mutually opposes. For example, in the case where each of the pair of hand-held portions 10 provided with the sandwiching portions 20 at the front ends is constituted by individual members, the state of the individual members before integrating the rear end side of each hand-held portion 10 At this stage, the concave portion 21 may be formed on the inner surface of the sandwiching portion 20 by pressing or the like.

  The example of the tweezers according to the present invention has been described above. However, the tweezers according to the present invention are not limited to the above-described examples, and can be appropriately changed without departing from the gist of the present invention.

  For example, as shown in FIG. 5, various shapes may be adopted as the shape of the sandwiching portion 20. 5 (a) shows the clip portion 20 having an oval shape, FIG. 5 (b) shows the clip portion 20 having a rhombus shape, and FIG. 5 (c) shows the clip portion. 20 is rectangular.

  Although not shown in the figure, the neck portion is not limited to the boundary portion between the handheld portion and the sandwiched portion, but the sandwiched portion and the handheld portion are sandwiched so that the sandwiched portion is continuous with the same width dimension at the tip of the handheld portion. You may make it the boundary part with a part become what is called a "size cylinder."
