Description
【考案の詳細な説明】 〔０００１〕 〔産業上の利用分野〕 この考案はピアノ鍵盤蓋を閉じるときに起し易い、特に幼児・児童の怪我を防止 する器具に関するものである。Description: [0001] [Industrial field of application] The present invention relates to a device which is apt to be raised when a piano keyboard lid is closed, and particularly to prevent injuries of infants and children.
〔０００２〕 〔従来の技術〕 従来の器具は油圧式であるが、テコ応用のため、人力による加圧で支点部分が折 損し易い。蓋が閉じている途中で人力で閉じる習慣は避け難く、折損の危険性が 極めて高い。 [0002] [Prior Art] Conventional equipment is of a hydraulic type, but due to lever application, the fulcrum portion is easily broken by pressure applied by human power. The habit of manually closing the lid while it is closed is unavoidable, and the risk of breakage is extremely high.
〔０００３〕 〔考案が解決しようとする課題〕 本考案はその欠点をなくするため、上からの相当の加圧をしても耐えられ、安全 性・耐久性・使用簡便であることを課題として研究をすゝめた。 [0003] [Problems to be solved by the invention] In order to eliminate the drawbacks of the invention, it is possible to withstand a considerable amount of pressure from above, and to have safety, durability, and easy use. I have completed my research.
〔０００４〕 〔課題を解決するための手段〕 このため空気圧を利用し、スポンヂの復元力を利用して緩やかに閉じることがで き、安全性・耐久性並に使用簡便であることを考案した。 [0004] [Means for Solving the Problems] Therefore, it has been devised that air pressure can be used to gently close by utilizing the restoring force of the sponge, which is safe, durable and as easy to use. .
〔０００５〕 〔作用〕 本案は以上のような構成であるから、人間の指や手首を損傷することなく、安全 にピアノ鍵盤蓋を閉じることができる。 [Operation] Since the present invention is configured as described above, it is possible to safely close the piano keyboard lid without damaging human fingers or wrists.
〔０００６〕 〔実施例〕 本考案を実施するため試作品によりテストした結果、十分機能することを確認し た。 [0006] [Example] As a result of testing a prototype to implement the present invention, it was confirmed that the device worked sufficiently.
〔０００７〕 〔考案の効果〕 本考案は以上のような構成だから耐久性と使用の簡便さと、何よりも折損等がな く、安全性が抜群に向上した。 [Advantages of the Invention] The present invention has the above-described structure, and has improved durability, convenience of use, and above all, safety without breakage.
又、低コストに作成できるので、より多くの利用が可能である。Further, since it can be produced at low cost, it can be used more.
