Description

本考案は、微小部材の掴み具であるピンセットに関するものである。 The present invention relates to tweezers that are gripping tools for minute members.

ピンセットは周知の通り開被方向に付勢されている操作脚部を備え、操作脚部の基部方側（挟圧部）において、指による挟圧開放で、操作脚部の先部（掴持部）で微小部材の掴持開放を行なうものである。 As is well known, the tweezers includes an operation leg that is urged in the opening direction, and the tip of the operation leg (gripping) is released by the clamping pressure release by the finger on the base side (clamping part) of the operation leg. Part) is used to hold and open the micro member.

前記のピンセットにおいて、挟圧部に指当てが付設されている器具が知られている。特許文献１（実開平３−４００６８号公報）には、リング状の指当てが開示されて、特許文献２（特開２００４−４２１４７号公報）には、合成ゴムまたは軟質合成樹脂製で、挟圧部に対応する取付面と、前記取付面の上下の一端側から外側方に延出して挟圧部と直交する面と翼片面を備えた指当てが開示されている。 In the tweezers described above, an instrument having a finger pad attached to the pinching portion is known. Patent Document 1 (Japanese Utility Model Laid-Open No. 3-40068) discloses a ring-shaped finger rest, and Patent Document 2 (Japanese Patent Laid-Open No. 2004-42147) is made of synthetic rubber or soft synthetic resin and has a pinch. There is disclosed a finger pad including a mounting surface corresponding to a pressure part, a surface extending outward from one end of the upper and lower sides of the mounting surface and orthogonal to the pinching part, and a blade surface.

実開平３−４００６８号公報。Japanese Utility Model Publication No. 3-40068. 特開２００４−４２１４７号公報。JP 2004-42147 A.

特許文献１，２に記載されている指当て部は、ピンセットの挟圧部における一定の箇所に設けられている。即ち指による挟圧開放の力の入れ具合、並びに指の開閉程度が自然に定まってしまい、指の位置や方向（挟み部の指し示す方向）を選択することができない。 The finger pad described in Patent Literatures 1 and 2 is provided at a fixed location in the pinching portion of the tweezers. That is, the degree of force applied to release the pinching pressure by the finger and the degree of opening / closing of the finger are naturally determined, and the position and direction of the finger (direction indicated by the pinching portion) cannot be selected.

使用者のくせや、掴持対象物の種類よって、指当て位置を変更したい場合には、指当てを備えていない器具を使用するか、或いは、指当てを外して使用することになる。 When it is desired to change the finger contact position depending on the habit of the user or the type of the object to be grasped, an instrument that does not have the finger contact is used, or the finger contact is removed.

そこで本考案は、位置の変更並びに指当て方向の変更ができる指当て部を備えたピンセットを提案したものである。 Therefore, the present invention proposes a tweezers equipped with a finger rest that can change the position and the finger rest direction.

本考案に係るピンセットは、先端に掴持部を備え、開被方向に付勢されている一対の操作脚部を備えてなるピンセットにおいて、裏面に装着部を備えた指当て体を、操作脚部における掴持部からの距離が相違する複数の固定位置を備えた装着受け部に、適宜選択装着してなることを特徴とするものである。 The tweezers according to the present invention is a tweezer having a gripping portion at a tip and a pair of operation legs biased in a covering direction. It is characterized by being appropriately selected and mounted on a mounting receiving portion having a plurality of fixed positions at different distances from the gripping portion.

従って使用者は、指当て体を所望位置の装着受け部に装着固定することで、使用者が最も使い易い位置に指当て体を備えるピンセットを得ることができる。 Therefore, the user can obtain the tweezers having the finger pad at the position where the user can use it most easily by mounting and fixing the finger pad on the mounting receiving portion at the desired position.

また本考案は、特に装着受け部を操作脚部に設けた透孔で形成した装着孔とし、前記装着孔がストレート形状の長孔、或いは装着孔部が適宜間隔で形成されると共に隣接装着孔間を幅狭の移動孔部とした瓢箪長孔であって、指当て体の装着部を、前記装着孔部に装着される円形軸部とし、且つ円形軸部が変形可能で適宜な弾性を備えた樹脂材で形成し、前記ストレート長孔の幅を円形軸部より幅狭としたり、瓢箪長孔の装着孔部を小径に形成してなるものである。 The present invention also provides a mounting hole formed by a through hole provided in the operation leg portion, and the mounting hole is a straight long hole, or the mounting hole portions are formed at appropriate intervals and adjacent mounting holes. An elongate hole with a narrow gap between the holes, the attachment portion of the finger pad is a circular shaft portion to be attached to the attachment hole portion, and the circular shaft portion is deformable and has an appropriate elasticity. The straight long hole is made narrower than the circular shaft part, or the long hole mounting hole part is formed with a small diameter.

而して指当て体の軸部を装着孔部に圧入すると、軸部の変形によって当該位置に指当て体が固定（強い力を加えないと移動しない程度）される。従って装着すべき装着孔部の選択で、指当て体のピンセット先端部からの距離を設定でき、また装着孔部に軸部を挿入し、適宜回転しても回転位置で固定されるので、指当て体の方向を任意に設定することができる。 Thus, when the shaft part of the finger pad is press-fitted into the mounting hole, the finger pad is fixed at the position by the deformation of the shaft part (to the extent that it does not move unless a strong force is applied). Therefore, by selecting the mounting hole to be mounted, the distance from the tweezers tip of the finger pad can be set, and even if the shaft is inserted into the mounting hole and rotated appropriately, it is fixed at the rotational position. The direction of the pad can be arbitrarily set.

本考案は、上記構成を備えたピンセットで、指当て体の位置並びに装着方向を、装着孔の形成範囲において、任意に選択装着することができ、ピンセット使用者の所望する指当て体を備えたピンセットを提供できたものである。 The present invention is a tweezers having the above-described configuration, and the position and mounting direction of the finger pad can be arbitrarily selected and mounted within the formation range of the mounting hole, and the finger pad desired by the tweezers user is provided. We were able to provide tweezers.
