Abstract

PROBLEM TO BE SOLVED: To provide an auxiliary tool for pressurizing a cross wrench, simply structured and allowing even a physically weak person to safely loosen an excessively tightened wheel nut.SOLUTION: The auxiliary tool for pressurizing a cross wrench includes a hook to serve as a point of support, a drive force transmission part to serve as a point of effect, a handle to serve as a point of effort, and a hook-and-loop fastener for bundling a wrench handle and the auxiliary tool.

Description

この発明は、締まりすぎて動きにくくなったホイールナットを小さな力で緩めることを可能にする十字レンチ補助具に関する。  The present invention relates to a cross wrench assisting tool that makes it possible to loosen a wheel nut that has become too tight and difficult to move with a small force.

従来、ホイールナットの着脱に十字レンチを使うことがあるが、ホイールナットが硬く締まりすぎている場合、力が弱い者は緩めることができない場合がある。
これを解決するために、レンチ部に補助具を接合してレンチ杆を延長するものが考案されている。（例えば、特許文献１参照。）Conventionally, a cross wrench is sometimes used for attaching and detaching the wheel nut. If the wheel nut is too hard and tightened, a person with weak force may not be able to loosen it.
In order to solve this problem, a device has been devised in which an auxiliary tool is joined to the wrench portion to extend the wrench rod. (For example, refer to Patent Document 1.)

特開２００９−２１４２８２号公報JP 2009-214282 A

これには、次のような問題がある。
レンチ部と補助具を緊密に接合するためには寸法の精度が高い必要があるが、それを確保することは容易ではない。寸法が合わない場合、レンチ部を破損する恐れがある。また、十字レンチと補助具との結合力に課題があり、使用中に補助具が脱落する恐れがある。This has the following problems.
In order to tightly join the wrench part and the auxiliary tool, it is necessary to have high dimensional accuracy, but it is not easy to secure it. If the dimensions do not match, the wrench may be damaged. In addition, there is a problem in the coupling force between the cross wrench and the auxiliary tool, and the auxiliary tool may fall off during use.

本発明は、簡易な構造で、かつ、安全に、締まりすぎたホイールナットを力が弱い者でも緩めることができる十字レンチ加圧補助具を実現することを目的としている。  An object of the present invention is to realize a cross wrench pressurizing assisting tool that can easily loosen a wheel nut that has been tightened excessively even with a weak force, with a simple structure.

本発明の十字レンチ加圧補助具は、当該補助具からレンチ杆に力を伝える際の支点となるフックと、作用点となる駆動力伝達部と、力点となる取っ手と、レンチ杆と補助具を結束する面ファスナーを有する構成とした。  The cross wrench pressurizing assisting tool of the present invention includes a hook serving as a fulcrum when transmitting a force from the assisting tool to the wrench, a driving force transmitting portion serving as an action point, a handle serving as a force point, a wrench tack and an assisting tool. It was set as the structure which has a hook_and_loop | surface fastener which binds.

本発明の十字レンチ加圧補助具は、十字レンチと一体になってレンチ杆が延長されることになり、より大きな力をナットに加えることができる。  The wrench pressure assisting tool of the present invention is integrated with the cross wrench and the wrench rod is extended, so that a larger force can be applied to the nut.

本発明の十字レンチ加圧補助具の側面図である。It is a side view of a cross wrench pressurization auxiliary tool of the present invention. 本発明の十字レンチ加圧補助具の使用時の平面図である。It is a top view at the time of use of the cross wrench pressurization auxiliary tool of this invention.

以下、本発明の実施の形態を図１、図２に基づいて説明する。  Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 and 2.

フック２は、レンチ杆の太さに見合ったものにする。
駆動力伝達部５は、十字レンチへの取り付けを容易にするため螺旋状にする。
面ファスナー３は、長方形のものの一辺をフック２と駆動力伝達部５の間に取り付ける。
幅は、レンチ杆と結束できる長さとする。使用時には、レンチ杆７と十字レンチ加圧補助具１とを結束するために使用する。
十字レンチ補助具は、２つをセットで使用する。The hook 2 should be suitable for the thickness of the wrench.
The driving force transmission unit 5 is formed in a spiral shape to facilitate attachment to the cross wrench.
The hook-and-loop fastener 3 is attached between the hook 2 and the driving force transmitting portion 5 on one side of a rectangular shape.
The width is the length that can be bundled with the wrench. In use, it is used to bind the wrench rod 7 and the cross wrench pressure assisting tool 1 together.
Use two wrench aids as a set.
