Abstract

【物品用途】;本設計所述“琴碼”主要係於琴面上撐張琴弦，並作為琴弦對琴皮發聲之傳導介質用途者。;【設計說明】;本設計琴碼整體外觀槪呈具倒角的三角柱狀體(請參閱立體圖)，其每一柱狀面和倒角面皆為往外弧凸的曲面，且每一倒角面與三角柱狀體的兩頂面相接處係採朝內削圓弧的設計；其中，於每一倒角面設有二個寬窄、長度皆不同的弦槽(請配合參閱前視圖、左側視圖及仰視圖)，每一弦槽係垂直於三角柱狀體的中心軸線；構成本設計由各個視角觀之皆充滿不同凹凸圓弧曲線所共構而成的豐富視覺變化。 本設計造型精巧別致，整體線條兼具不同凹凸圓弧曲線美感，不論從任一視角觀之，充滿變化又極為美觀實用，堪稱琴碼的一大突破創新設計；據此，爰依法提出設計專利申請，望 貴審查委員明察，早日賜予專利，實感德便。;使用狀態參考圖係本設計琴碼裝設於二胡樂器上的狀態。[Purpose of the item]; The "keyboard" mentioned in this design is mainly used to stretch the strings on the surface of the piano and serve as a conductive medium for the sound produced by the strings to the piano skin. ;[Design Description];The overall appearance of this design piano is in the form of a triangular prism with chamfers (please refer to the three-dimensional diagram). Each of its cylindrical surfaces and chamfered surfaces are curved surfaces that are convex outward, and each chamfer The connection between the surface and the two top surfaces of the triangular prism is designed with an inward arc. There are two chord grooves with different widths and lengths on each chamfered surface (please refer to the front view, left side) (view and bottom view), each chord groove is perpendicular to the central axis of the triangular prism; this constitutes the rich visual changes of this design, which are filled with different concave and convex arc curves from every viewing angle. The shape of this design is exquisite and unique, and the overall lines have the beauty of different concave and convex arc curves. No matter viewed from any angle, it is full of changes and extremely beautiful and practical. It can be called a breakthrough and innovative design of the piano code. Based on this, Yuan proposed the design in accordance with the law. I hope that the review committee will take a clear look at the patent application and grant the patent as soon as possible. ;The reference picture of the usage state shows the state of the designed keyboard installed on the erhu instrument.
