翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク John Joseph Rawlings ： ウィキペディア英語版 John Joseph Rawlings thumb John Joseph Rawlings was a British engineer and inventor of the wall plug, also known from his name as the ''rawlplug''. He invented it in around 1910-11, registered a patent in 1911, trademarked the ''rawlplug'' name in 1912 and was granted the patent in 1913. In 1919 his company, formerly known as the Rawlings Brothers, was renamed to Rawlplug Ltd. ==Wall plug== The original device was a jute fibre cylinder inserted into a hole drilled in the masonry and into which the screw was inserted. The deeper the screw penetrated, the more the fibre expanded and the greater the grip against the masonry. The jute was replaced by a thermoplastic plug in the 1960s, injection moulded singly, or in multiples attached together by the original sprue. Each plug can be easily twisted off the sprue when needed. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「John Joseph Rawlings」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
