Abstract
An improved key for keyboard musical instruments, being particularly suited for reduced width keys, provides for greater structural stiffness and torsional rigidity to improve the feel and response of the key. The key comprises a playing end member mounted on top of one end of a bracing member and a key shank mounted on top of the second end of the bracing member, with the free end of the key shank able to engage a capstan mechanism.

- a key shank having a first and second end, said second end adapted to engage a capstan mechanism of a piano;
- and
- a bracing member having a first and second end, said second end connected to the first end of said key shank, and said first end of the bracing member having a top surface;
- wherein a portion of the top surface of the first end of said bracing member is connected to said playing end member along a portion of the bottom surface of said playing end member.
A key for a musical instrument comprising:
- a bracing member having a first and second end;
- a playing end member mounted on top of the first end of said bracing member;
- and
- a key shank having a first end, said first end mounted on top of the second end of said bracing member.
The key as in claim 9 wherein said bracing member is integrally connected to said playing end member and said key shank.
A key unit for a musical instrument comprising:
- a first key, said first key comprising
- a playing end member;
- a key shank, having a first and second end, said second end adapted to engage a capstan mechanism of a piano;
- and
- a bracing member disposed below said key shank and said playing end member, said bracing member having a first and second end, wherein said first end is connected to the first end of said key shank and said second end is connected to said playing end member, said bracing member further comprising a center portion disposed between said first and second ends, said center portion having a width greater than the width of said key shank;
- and
- a second key, said second key comprising
- a playing end member;
- a center portion connected to said playing end member, said center portion disposed above said bracing member of said first key and having substantially the same width as the center portion of said bracing member of said first key;
- and
- a key shank, having a first and second end, said second end adapted to engage a capstan mechanism of a piano, said first end connected to said center portion.
