Abstract

Abstract Disclosed is a guitar string tuning device. The device comprises a tuning peg for winding therearound and unwinding therefrom a guitar string thereby to tune the guitar string, the tuning peg having a slit which is defined at an upper end thereof and a worm wheel which is formed at a lower end thereof; a housing for accommodating the tuning peg therein in a manner such that the tuning peg is maintained in an upright posture; a manipulating lever having a worm which is formed at one end thereof in a manner such that the worm enters into the housing to be meshed with the worm wheel of the tuning peg which is accommodated in the housing and a tuning handle which is formed at the other end thereof; and a clamping section for clamping the guitar string to the tuning peg which is rotated by manipulating the tuning handle, the clamping section including a clamping shaft which has a predetermined width extending in a lengthwise direction of the guitar string which is inserted through the slit of the tuning peg, the clamping section further including threadedly movable means for allowing the clamping shaft to be moved in a direction wherein the clamping shaft squeezes the guitar string against a bottom surface of the slit defined in the tuning peg.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 216 words
A guitar string tuning device comprising: a tuning peg for winding therearound and unwinding therefrom a guitar string thereby to tune the guitar string, the tuning peg having a slit which is defined at an upper end thereof and a worm wheel which is formed at a lower end thereof; a housing for accommodating the tuning peg therein in a manner such that the tuning peg is maintained in an upright posture; a manipulating lever having a worm which is formed at one end thereof in a manner such that the worm enters into the housing to be meshed with the worm wheel of the tuning peg which is accommodated in the housing and a tuning handle which is formed at the other end thereof; and a clamping section for clamping the guitar string to the tuning peg which is rotated by manipulating the tuning handle, the clamping section including a clamping shaft which has a predetermined width extending in a lengthwise direction of the guitar string which is inserted through the slit of the tuning peg, the clamping section further including threadedly movable means for allowing the clamping shaft to be moved in a direction wherein the clamping shaft squeezes the guitar string against a bottom surface of the slit defined in the tuning peg.
Claim 2
Dependent Claim 216 words
A guitar string tuning device comprising: a tuning peg for winding therearound and unwinding therefrom a guitar string thereby to tune the guitar string, the tuning peg having a slit which is defined at an upper end thereof and a worm wheel which is formed at a lower end thereof; a housing for accommodating the tuning peg therein in a manner such that the tuning peg is maintained in an upright posture; a manipulating lever having a worm which is formed at one end thereof in a manner such that the worm enters into the housing to be meshed with the worm wheel of the tuning peg which is accommodated in the housing and a tuning handle which is formed at the other end thereof; and a clamping section for clamping the guitar string to the tuning peg which is rotated by manipulating the tuning handle, the clamping section including a clamping shaft which has a predetermined width extending in a lengthwise direction of the guitar string which is inserted through the slit of the tuning peg, the clamping section further including threadedly movable means for allowing the clamping shaft to be moved in a direction wherein the clamping shaft squeezes the guitar string against a bottom surface of the slit defined in the tuning peg.
Claim 3
Dependent Claim 107 words
The guitar string tuning device as claimed in claim 1 , wherein the threadedly movable means of the clamping section comprises: an externally threaded portion formed on a circumferential outer surface at the upper end of the tuning peg in such a manner that the externally threaded portion extends by a predetermined distance which substantially corresponds to a depth of the slit; and an internally threaded locking sleeve threadedly locked to the externally threaded portion, the clamping shaft being mounted in and to the internally threaded locking sleeve in such a manner that the clamping shaft can be fitted into the slit defined in the tuning peg.
