Patent ID: 7285709

Claim:
A modular automated assistive guitar that comprises four subsystems/modules (i.e., a base assembly, a pick assembly, a strumming mechanism and a fretting mechanism) in combination with a guitar to form an automated musical device that can be played by an individual with a range of mental and physical abilities wherein said modular automated assistive guitar comprises: (a) a base assembly module having a substantially flat surface that is appropriately sized and shaped to receive a guitar, and that comprises fastening means to securely fasten a guitar to the base; (b) a pick assembly module that provides means for strumming the guitar comprising a pick held in resilient contact with the strings of the guitar as the pick moves in a forward direction and a reverse direction across the strings of the guitar; said pick assembly module being located above the strings of the body of the guitar and fixedly attached to the strumming mechanism; (c) a strumming mechanism module that comprises a moving slider (strumming bearing) that is slidably mounted on and runs the length of a linear (strumming) guide and connected to said pick assembly; wherein the moving slider and pick assembly are jointly and rotatably connected to a connecting rod, which in turn is rotatably connected to a crank and motor means for turning said crank at variable rates at the option or discretion of an operator, thereby causing the pick assembly mounted on the moving slider (strumming bearing) to reciprocate along the length of the linear (strumming) guide and causing the pick assembly to reciprocate perpendicularly across the strings of the guitar; and (d) a fretting mechanism module that comprises a slider base plate fixedly attached to two linear bearings which, in turn, are slidably mounted on two linear guides of a fretting clamp on either side of the neck of the guitar, said linear guides and fretting clamp being fixedly attached to the base assembly module, a slide that is mounted to traverse the neck of the guitar and is in slideable contact with the strings of the guitar, and means for compressing the slide against the strings of the guitar at variable times and pressures at the option or discretion of an operator.
