Connector for string instrument and harness

A connector for a string instrument and a harness, comprising:

• an engaging member which has a casing provided with an engaging chamber which is open toward a string instrument side, at least two engaging pieces which are accommodated in said engaging chamber for movement forward and backward in the radial direction of said chamber, a resetting spring which biases said engaging pieces toward each other, an operation knob engagable with said engaging pieces for retracting said engaging pieces against the bias of said resetting spring when the knob is manually rotated in the circumferential direction, and a mounting means for positioning said casing at a position inside a harness and said operation knob on the outside of the harness;
• a fixing member which has a protrusion having a top part which has a size for causing said engaging pieces to retract against said resetting spring when said protrusion is pushed into said engaging chamber of said engaging member and having an engaging recess positioned at a position nearer the string instrument than the top part and shaped for being engaged by said engaging pieces when said protrusion is pushed into said engaging chamber;
• an elastic cover on the base of said protrusion and an elastic sheet on the face of said elastic cover which faces away from said engaging member, said elastic cover extending along the sides of said protrusion said engaging member, said elastic cover and said elastic sheet being adapted to be engaged between the edge of said casing of said engaging member and a string instrument when said protrusion is engaged inside said engaging chamber of said engaging member;
• and
• means for fixing said protrusion to a string instrument.

A connector for a string instrument and a harness, comprising:

• an engaging member having a casing provided with an engaging chamber which is open at a string instrument side, at least two spaced opposed pieces slidably mounted in said casing for movement toward and away from each other in a radial direction within said chamber, a resetting spring means coupled with said engaging pieces and urging said engaging pieces toward each other, an operation knob rotatably mounted in said casing and having a shaft extending toward said engaging chamber, pins on one of said shaft and said engaging pieces and slots on the other of said shaft and said engaging pieces, said pins and slots being engaged for, when said knob is turned in one direction of rotation, urging said engaging pieces apart against the action of said resetting spring, and a harness mounting means for mounting said engaging member on said harness with said casing at a position inside the harness and said operation knob on the outside of the harness;
• and
• a fixing member having a protrusion having a top part having a size causing said engaging pieces to retract against the action of said resetting spring when said protrusion is pushed into said engaging chamber and having an engaging recess positioned at a position toward the string instrument end of said fixing member and having a shape for being engaged by said pieces when said protrusion is pushed into said engaging chamber, and a fixing means for fixing said protrusion to a string instrument.
