Capo

A capo for use with a stringed instrument having a plurality of strings and a neck, said neck comprising a fingerboard and a back, said capo comprising:

• a string engaging arm that is adapted to extend across the fingerboard above the strings and in use press against the strings;
• a clamping arm that is adapted, in use, to extend across and engage the back of the neck;
• a pivotal connection to pivotally interconnect the clamping arm to the string engaging arm at a position along said arms that is arranged, in use, to be adjacent said neck such that the arms can be pivoted relative to each other in order to, in use, fit and clamp the strings and neck between said arms;
• and
• a releasable locking mechanism which is operable to selectively lock and unlock the pivotal connection and the relative pivotal movement of the clamping arm and string engaging arm at least in a particular direction, wherein the locking mechanism comprises at least one wedge, and at least one co-operating tapered recess that is defined by and between a first and second oppositely facing surfaces which move relative to each other during pivotal movement about the pivotal connection of the clamping and string engaging arms, the wedge adapted to be engaged within the recess and thereby restrict relative movement of the first and second surfaces and thereby lock the pivotal connection and prevent movement of the arms in at least one direction.
