摘要 | A versatile, high performance grand piano includes a keyboard having 92 keys thereon as opposed to the conventional 88 keys found on most pianos. Furthermore, each key hammer strikes four dedicated strings as opposed to the three shared strings found on conventional pianos. The string construction eliminates the need for string sets to be shared with adjacent keys so that tuning or breakage of a string only affects a single key as opposed to adjacent keys. | ||||||

说明书全文 | This application is entitled to the benefit of provisional application No. 60/346,421 under 35 U.S.C. Section 119(e), filed on Nov. 9, 2001. The present invention relates to a piano having 92 keys as opposed to the conventional 88 keys found on most pianos thereby providing enhanced versatility and performance. Conventional pianos include 88 keys, each of which operates a hammer that strikes a set of three adjacent strings-a right string, a left string and an intermediate string. The right and left strings for each key are shared with the adjacent keys. For example, the right string for a given key functions as the left string for the key immediately to the right of the given key. Likewise, the left string is shared with the left adjacent key and becomes the right string therefor. Accordingly, if a string associated with a given key breaks during a concert or other performance, the sound quality and volume of two notes are affected. Similarly, tuning a single string will affect two notes simultaneously. Furthermore, with a traditional 88-key piano, the middle C note is not centrally positioned on the keyboard. Finally, a conventional piano includes sets of treble and bass strings that overlap making its impossible to individually expose either set. The present invention satisfies the above-described problems by providing a 92-key piano that includes an additional four notes for enhanced versatility and which allows the middle C note to be positioned at the keyboard median. Furthermore, each key includes four dedicated, unshared strings that emit a higher quality sound and do not affect other notes if broken or tuned. Additionally, the bass strings and treble strings are segregated allowing either or both to be exposed with a pair of lids, each overlaying a designated set. The present invention discloses a 92-key piano including a conventional housing having a keyboard and a hollow interior containing conventional piano sound producing means such as strings, hammers and similar items. The keyboard includes 92-keys, preferably 38 black keys and 54 white keys. The additional four keys are located to the left side of the original 88 keys which are tuned up by four notes as compared to a conventional 88 key piano. Accordingly, the additional four notes included in the 92-key board increases the playing range. In addition, each key operates a hammer that strikes four designated strings rather than the conventional three strings resulting in a more intense and powerful sound than that created with the three string arrangement. Furthermore, each string includes a designated tuning pin whereby each of the four strings for a designated key can be separately tuned so as not to affect the sound quality of any adjacent keys or notes. It is therefore an object of the present invention to provide a piano having a greater range in which a user may play. It is another object of the present invention to provide a piano whereby each key has designated strings that are not shared by other keys so that a string failure only affects the designated key. It is yet another object of the present invention to provide a piano in which each string has a designated tuning pin whereby tuning one string does not affect the playing quality of an adjacent key. Other objects, features and advantages of the present invention will become readily apparent from the following detailed description of the preferred embodiment when considered with the attached drawings and the appended claims. Now referring to As depicted in Now referring to The advantage of the above described four string arrangement is now apparent. A conventional piano includes a set of three strings formed with a single string attached at each end to a tuning pin having an intermediate portion wrapped about a string pin. Each string is shared with an adjacent set to form a three string set. Accordingly, tuning a string will affect two notes. The four string construction according to the present invention allows each string to be separately tuned with its designated tuning pin without affecting any other notes. Now referring to As indicated above, the present invention provides a uniquely designed piano having additional keys and notes thereby providing a greater range within which a user may play. However, the device is not limited to the exact details of construction and enumeration of parts described above. For example, the size, shape and materials and construction of the device may be varied to suit a particular application. Although there has been shown and described the preferred embodiment of the present invention, it will be readily apparent to those skilled in the all that modifications may be made thereto which do not exceed the scope of the appended claims. Therefore, the scope of the invention is only to be limited by the following claims |
