Abstract
The present disclosure relates to a piano-action. The piano-action may comprises a first moving component including a concavity structure, a second moving component including a convexity structure, wherein the convexity structure and the concavity structure are configured to match each other and capable of being clipped together, and a third moving component being thin and flexible and configured to fixedly fit between the first moving component and the second moving component when the convexity structure of the second moving component is clipped into the concavity structure of the first moving component.
Claims21
A piano-action, comprising:
- a first moving component including a concavity structure;
- a second moving component including a convexity structure, wherein the convexity structure and the concavity structure are configured to match each other and capable of being clipped together;
- and
- a third moving component being thin and flexible and configured to fixedly fit between the first moving component and the second moving component when the convexity structure of the second moving component is clipped into the concavity structure of the first moving component.
7-10. (canceled)
A piano-action, comprising:
- a moving device, the moving device including one or more moving components, wherein at least one of the moving components includes an elastic portion, the one or more moving components are configured to move, relatively to each other, through deformation of the elastic portion of the at least one moving component.
16-20. (canceled)
A piano-action, comprising:
- a first moving component including a convexity structure;
- a second moving component including a concavity structure;
- and
- a connecting component configured to rotatably connect the first moving component to the second moving component by assembling the convexity structure into the concavity structure,
- wherein the convexity structure and the concavity structure have different radians and are configured to match each other.
