Abstract

【課題】火ばさみは繰り返し使用しているうちに、末端部の弾性が弱まり、先端部が開いた状態に復元しにくくなることがよくあり、かかる事態を改善すべく、先端部の開力の経時的低減を可及的に抑制可能な火ばさみを提供する。【解決手段】火ばさみ１５は２つのアーム部１１、１１を含み、２つのアーム１１、１１はステンレス等の金属板を用いて同じ長さに構成され、２つのアーム部１１、１１の一端は弾性を有するほぼ円弧状のバネ部１０によって相互に連結される。このバネ部１０により、２つのアーム１１、１１は相互に所定の角度をもって開いた状態に付勢されている。【選択図】図１[PROBLEMS] In many cases, fire scissors often lose their elasticity at the end, making it difficult to restore the tip to an open state. A fire scissor capable of suppressing the reduction of force with time is provided. SOLUTION: A fire scissor 15 includes two arm portions 11, 11. The two arms 11, 11 are configured to have the same length using a metal plate such as stainless steel, and the two arm portions 11, 11 One end is mutually connected by the substantially arc-shaped spring part 10 which has elasticity. The two arms 11 and 11 are biased by the spring portion 10 so as to be opened at a predetermined angle. [Selection] Figure 1

Description

本考案は回収作業や分別作業などに用いる火ばさみに関し、より詳しくは先端部の開く力が経時的に減退しない火ばさみに関する。   The present invention relates to fire scissors used for collection work, sorting work, and the like, and more particularly to fire scissors in which the opening force of the tip portion does not decrease over time.

廃品や投棄ゴミ等を手で直接取り扱うことは望ましくない。そこでいわゆる火ばさみを用いて廃品や投棄ゴミを挟んで分別し、あるいは拾い上げることが行われている。   It is not desirable to directly handle waste or dumped garbage by hand. Therefore, so-called fire scissors are used to separate or pick up waste or dumped garbage.

図４乃至図６は従来汎用の火ばさみ４を示すものである。バネ部２が弾性を備えた支点となっており、ばねの力で一対のアーム３，３が緩く開く状態になるように形成されている。すなわち、図６に示されるようにアーム３，３同士が近接した状態からバネの力で図４に示されるアーム３，３が開いた状態に復元するよう付勢されている。   4 to 6 show a conventional general-purpose fire scissor 4. The spring portion 2 is a fulcrum having elasticity, and is formed so that the pair of arms 3 and 3 are loosely opened by the force of the spring. That is, as shown in FIG. 6, the arms 3 and 3 are biased so as to be restored from the state in which they are close to each other to the state in which the arms 3 and 3 shown in FIG.

また、火ばさみ４の先端部１は物品をはさんで落とさないようにするために広くへら状になっているか、凹凸がついていて掴む対象に食い込むよう形成されている。   Further, the tip 1 of the fire scissors 4 has a wide spatula shape so as not to drop the article between them, or is formed so as to bite into the object to be grasped.

特許文献１には、先端部近傍に補強用のリブが設けられた火ばさみが開示されている。   Patent Document 1 discloses a fire scissor in which a reinforcing rib is provided near the tip.

火ばさみは繰り返し使用しているうちに、末端部の弾性が弱まり、先端部が開いた状態に復元しにくくなることがよくある。本考案はかかる事態を改善すべく、先端部の開力の経時的低減を可及的に抑制可能な火ばさみを提供することを目的とする。   During repeated use of fire scissors, the elasticity of the end portion is weakened and it is often difficult to restore the tip portion to an open state. In order to improve such a situation, an object of the present invention is to provide a fire scissor capable of suppressing as much as possible the reduction of the opening force of the tip portion over time.

（１） 請求項１に記載の考案は、一対のアームが、バネ部を介して開方向に付勢された状態で、対向連結された火ばさみにおいて、アームの内側に、アームが開く方向に付勢する弾性体を取り付けて構成した。   (1) According to the first aspect of the present invention, in the state where the pair of arms are biased in the opening direction via the spring portion, the arms open inside the arms in the opposed scissors. An elastic body biased in the direction was attached.

（２） 請求項２に記載の考案は、請求項１記載の火ばさみにおいて、弾性体を板バネを用いて構成した。   (2) The invention according to claim 2 is the fire scissors according to claim 1, wherein the elastic body is configured using a leaf spring.

（３） 請求項３に記載の考案は、請求項１記載の火ばさみにおいて、弾性体を押しバネを用いて構成した。   (3) The invention described in claim 3 is the fire scissor according to claim 1, wherein the elastic body is configured using a push spring.

（４） 請求項４に記載の考案は、請求項１記載の火ばさみにおいて、弾性体をゴム製の補強材を用いて構成した。   (4) The invention described in claim 4 is the fire scissor according to claim 1, wherein the elastic body is configured using a rubber reinforcing material.

図１乃至図３に示すように本考案にかかる火ばさみは、一対のアーム１１，１１の間に弾性体として請求項２に記載の考案では板バネ１２が、請求項３に記載の考案では押しバネ１３が、請求項４ゴム製の補強材１４が介在させてある。これら弾性体はアーム１１を開く方向に付勢することから、バネ部１０によるアーム１１に対する開力が経時的に低減しても、火ばさみの先端部の開力を維持することが可能となるのである。   As shown in FIG. 1 to FIG. 3, the fire scissors according to the present invention are elastic members between a pair of arms 11, 11. In the present invention, the push spring 13 is provided with a rubber reinforcing member 14. Since these elastic bodies bias the arm 11 in the opening direction, it is possible to maintain the opening force of the tip portion of the fire scissors even if the opening force of the spring portion 10 on the arm 11 decreases with time. It becomes.

以下、好ましい本考案の構成要素の実施形態につき、図面を参照しながら概説する。なお、本考案構成要素の実施形態は、下記の実施形態に何ら限定されることはなく、本考案の技術的範囲に属する限り、種々の形態を採りうる。  Hereinafter, preferred embodiments of the components of the present invention will be outlined with reference to the drawings. In addition, embodiment of the component of this invention is not limited to the following embodiment at all, As long as it belongs to the technical scope of this invention, various forms can be taken.

本考案にかかる火ばさみ１５は、図４乃至図６に示される従来の火ばさみ４に弾性体を付加したものであり、その基本構造は火ばさみ４と同様である。すなわち、本考案に係る火ばさみ１５は２つのアーム部１１、１１を含み、２つのアーム１１、１１はステンレス等の金属板を用いて同じ長さに構成され、２つのアーム部１１、１１の一端は弾性を有するほぼ円弧状のバネ部１０によって相互に連結される。このバネ部１０により、２つのアーム１１、１１は相互に所定の角度をもって開いた状態に付勢されている。   The scissors 15 according to the present invention is obtained by adding an elastic body to the conventional scissors 4 shown in FIGS. 4 to 6, and the basic structure thereof is the same as that of the scissors 4. That is, the fire scissor 15 according to the present invention includes two arm portions 11, 11, and the two arms 11, 11 are configured to have the same length using a metal plate such as stainless steel. The one ends of 11 are mutually connected by a substantially arc-shaped spring portion 10 having elasticity. The two arms 11 and 11 are biased by the spring portion 10 so as to be opened at a predetermined angle.

本考案においては、アーム１１,１１間にアーム１１，１１を開く方向に付勢する弾性体が介在させてある。弾性体としては図１に示すように折曲した板バネ１２、図３に示すように押しバネ１３、図３に示すように補強材１４が用いられる。補強材１４は弾性を備えたゴム製の略直方体であり、素材としては天然ゴムやＳＢＲゴムなどを利用可能である。   In the present invention, an elastic body that urges the arms 11 and 11 in the opening direction is interposed between the arms 11 and 11. As the elastic body, a bent leaf spring 12 as shown in FIG. 1, a pressing spring 13 as shown in FIG. 3, and a reinforcing member 14 as shown in FIG. 3 are used. The reinforcing material 14 is a rubber substantially rectangular parallelepiped having elasticity, and natural rubber or SBR rubber can be used as a material.
