Abstract
A capo device for selectively altering the pitch range of a stringed instrument, the capo device being adapted to engage a variety of stringed instrument neck sizes and/or geometries while maintaining desired sound and pitch quality.
Claims14
A capo device for stringed instruments, comprising:
- a first extension member having a first portion and a second portion, said first portion and said second portion being in a substantially L-shaped configuration;
- a second extension member pivotally coupled with said first extension member at a hinged joint positioned proximate to an end of said second portion of said first extension member and an end of said second extension member;
- an adjustment mechanism comprising a tension knob having a substantially central longitudinal axis and coupled with said second extension member, such that the substantially central longitudinal axis of said tension knob remains stationary with respect to said second extension member;
- and a support member pivotally coupled with said second extension member, wherein said support member extends from said second extension member substantially toward said first portion of said first extension member,
- wherein movement of said tension knob causes rotational movement of said first extension member about said hinged joint relative to said second extension member to move said first extension member and said second extension member between an open position and a closed position.

A capo device for stringed instruments, comprising:
- a first extension member,
- a second extension member pivotally coupled with said first extension member at a hinged joint, such that said first extension member and said second extension member form a substantially U-shaped frame;
- an adjustment mechanism coupled with said first and second extension members, said adjustment mechanism comprising a tension knob having a substantially central longitudinal axis and coupled with said second extension member, such that the substantially central longitudinal axis of said tension knob remains stationary with respect to said second extension member;
- and a support member pivotally coupled with said second extension member, said support member extending from said second extension member substantially toward the center of said substantially U-shaped frame,
- wherein said first extension member is configured to detachably couple with a first side of an object inserted into the center of said substantially U-shaped frame and said support member is configured to detachably couple with an opposing side of said object when said object is within the center of said substantially U-shaped frame, and
- wherein movement of said tension knob causes rotational movement of said first extension member about said hinged joint relative to said second extension member to move said first extension member and said second extension member between an open position and a closed position and thereby selectively tighten or loosen said first extension and said second extension member around said object substantially within the center of said substantially U-shaped frame.
