Abstract

Abstract A stringed bender attachment for selectively changing the tension imposed on a selected string of a string instrument of the guitar family including a frame attached to the instrument body opposite the neck of the instrument having mounted thereon a rod having an axis transverse to the axis of a selected string and a rocker arm pivotally mounted on the rod and having the end of the selected string anchored thereto. Pivotal movement of the rocker arm slightly changes the tension imposed on the selected string, and actuating means are provided including an extended arm actuable by body movement of the performer during play for bending or changing the tension on the selected string. A second bender means may be mounted on the rod for changing the tension of a second string by digital movement by the performer. Selectively adjustable means are provided for limiting the amount of change of tension.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 116 words
A string bender for mounting on a stringed instrument of the guitar family having a set of tensioned strings and adapted to be carried by a performer in use with the strings lying adjacent to the forwardly directed face of the instrument, said device comprising: a bracket adapted to be mounted on a guitar at its lower end including means anchoring a selected one of the tensioned strings; means carried by the bracket for changing the tension imposed on the selected string; and means actuable by body movement of the performer for actuating the changing means, said actuating means including an arm mounted on the bracket and projecting rearwardly from the lower end of the guitar.
Claim 2
Dependent Claim 116 words
A string bender for mounting on a stringed instrument of the guitar family having a set of tensioned strings and adapted to be carried by a performer in use with the strings lying adjacent to the forwardly directed face of the instrument, said device comprising: a bracket adapted to be mounted on a guitar at its lower end including means anchoring a selected one of the tensioned strings; means carried by the bracket for changing the tension imposed on the selected string; and means actuable by body movement of the performer for actuating the changing means, said actuating means including an arm mounted on the bracket and projecting rearwardly from the lower end of the guitar.
Claim 3
Dependent Claim 239 words
A string bender device for selectively mounting on and demounting from a stringed instrument of the guitar family adapted to be carried by a performer in use and having a set of parallel tensioned strings extending upwardly from adjacent the lower end of the instrument and lying adjacent to the forwardly directed face of the instrument body, the lower end of the instrument body being provided with an existing opening for receiving the shank of a connecting element for selectively attaching one end of a supporting strap to the instrument body, said device comprising: an L-shaped bracket and means for mounting the bracket on the lower end of the body, including an upper leg juxtaposed on a portion of the forwardly directed body face adjacent to said body lower end, and a lower leg extending normal to the upper leg in juxtaposed relation with the lower body wall and having formed therein an aperture registering with said body opening, said mounting means including a connecting element having a shank extending through the aperture and seated in the opening; means carried by the bracket for anchoring the lower end of a selected one of the tensioned strings, including means for changing the tension imposed on the selected string; and movable means for actuating the changing means, including an arm projecting rearwardly from the instrument adjacent said lower end and adapted to be moved by lateral body movement of the performer.
Claim 4
Dependent Claim 239 words
A string bender device for selectively mounting on and demounting from a stringed instrument of the guitar family adapted to be carried by a performer in use and having a set of parallel tensioned strings extending upwardly from adjacent the lower end of the instrument and lying adjacent to the forwardly directed face of the instrument body, the lower end of the instrument body being provided with an existing opening for receiving the shank of a connecting element for selectively attaching one end of a supporting strap to the instrument body, said device comprising: an L-shaped bracket and means for mounting the bracket on the lower end of the body, including an upper leg juxtaposed on a portion of the forwardly directed body face adjacent to said body lower end, and a lower leg extending normal to the upper leg in juxtaposed relation with the lower body wall and having formed therein an aperture registering with said body opening, said mounting means including a connecting element having a shank extending through the aperture and seated in the opening; means carried by the bracket for anchoring the lower end of a selected one of the tensioned strings, including means for changing the tension imposed on the selected string; and movable means for actuating the changing means, including an arm projecting rearwardly from the instrument adjacent said lower end and adapted to be moved by lateral body movement of the performer.
