TIPPING BRIDGE FOR ELECTRIC GUITAR

Abstract: A tilting bridge for a string instrument is disclosed which includes a fine adjustment system. The fine adjustment system utilizes a wedge (4) having a cask plug (3) at one end and an anchor piece (6) at an opposite end to which the string is attached. The wedge (4) is pivotally connected (20) to the bridge at a support piece (21). The movement of the cask plug (4) adjusts the tension of the strings. The tilting bridge is tipped around the axes (9) of the plate (10) by action of the lever (13) by coaction of the billet (8) with a cam disk (12).

Description: GυrTAR DESCRIPTION OBJECT OF THE INVENTION Title invention is about a bridge for a. electric guitar that has a particular geometric ___chanism that allows the fine timing of the strings with a large rarg^n of regulation ever established before, it also incorporates 3 tighten and wβtigbtβn system of the strings through the activation of the vibrator lever, in which it incorporates a can disc and a ri ping sheer billet, preventing the intervention of piers , end. mat-inr ic possible for he strings to be iαdependely cane, or nheα one of the strings breaJc. Anαther o jective of this inrention consist of the incorporation o£.the tuning fork oscillator that allows its direct contact with the microphone facilitating the ύnediate natural tone for the £ine rnning o£ the guitar or any other instroaw-tt. INVENTIONSANTECEDENT The aethod used co aodi±y s e t ~~τ n ~ on the strings of a electric gtii-mr by the lweana of a tribr_rεor consist of a bridge supported by piers αith up and dotm displacement obtaining respectively a larger or .-_ral3.er tension of the strings. The tension of all the strings that are being join to the bridge its defined According to the grade of ecnpression of the bridge. this dβtβr__neε that if a string breaks it causes the rest of the strings to be out of tune and the guitar is not playable anymore until the string is replaced and the guitar tune again. And to replace strings in si__il__r syste__s you. have to go over fine tuning and balance of the tension of each string, because according to the number of strings available In the guitar the e fort over the pier is going to vary. Another problest occurs as a consequence that tension level of the strings is limited by the displaceaenr of the bridge that whan it deeceada it makes contact with the guitar's body. INVENTION DESCRIPTION This invention has for an objective a tipping bridge for a electric guitar fine adjustment for pexaanent nrπiπg and tuning fork incorporated * that standout fundamentally by tfre- mechanisi- that incorporates the bridge, that presents a back sod forth mαvesasxte in a lengthways and a lightly tipping that allows to regulate the tension of the string tfithin a major range of possibilities, of the ones already obtain. The bridge presents a structure with two sectors at different levels with a iπcli-nr pitch , finding on she upper sector a series of slots in crwTcordauct with the cask plug chat It goes through and are join to the lower wedges that have a similar form to the brlgβ,coating out of the lower sector of the wedges the tie down points of the strings that coses out through the slots of the lower sector of the bridge, being the wedge and the bridge join together by a support piece, which Is run through by an axis ,and around which the wedges tip whan, the cask plug moves, this support prevents the falling down of the wedges when the strings are removed. In the lower sector of the bridge , nearby the ends, he guiding tracks of the strings are situated that can be acrve lengthways to regulate the tune of the string. The fine tuning of each of the string. Is obtained by the displacement of each one of the cask plugs , producing the noveaeat of the wedges and the associated displacement of the tie daws pieces of the strings tighten or uatighten them, according to way of the displacement of the cask plugs. __ vertical sheet billet prolongs fxcta the Lower sector of the bridge, the sheet billet tips around a turning axis belonging to a plate that is attached to the guitar's body , inrotporar-ng such a plate a regulator sc ew applied over each regulator salient in tee height of the plate that nerve guided by a one of its ends and determine* the associated displacement of the bridge end as a consequence of the strin in relationship of the mast. The instant tighten and untigtttβn of all of the strings can be achieved, by the vibrator lever , consisting the associated mechanism to the vibrator in a can disk join to the axis of the lever which is found in permanent contact with the sheet billet mentioned before , resulting frees the lever movement in the horizontal plain , che turning of the ca__ disk and. the di-rplaoeαaent of the sheet billet , which originates the pulling of the bridge and the tighten or uadgntec of the strings depending in the way of displacement. The cam disk has a small flat surface ia contact uith the side face of the sheet billet in the resting state of the lever. Fran this flat face it prolongs upward a surface with a larger curve than the sur ace that prolongs downward frαa the other end of the flat face. is a consequence of the turn of the vibrator's lever upwards it originates the push of the sur ace with the larger curvature over the sheet billet producing its lengthways displacement , and the bridge tighnening the strings. In the case that the displacement of the lever is in opposite direction , che sheet billet mates contact with the surface of less curvature of the cam disk and it produces the displacement of the sheet billet iα the opposite direction and with this of the bridge untlghteαing of the strings. The turning axes of the vibrator lever in being supported by each salient of the guitar's body and its end is found associated to a hock plate oin by two piers to another sector of the guitar's body , which function is to achieve the desired tension of the lever. The bridge of the guitar presents as a unique aspect the incorporation of a tuning fork that is located en side of the lower sector of the bridge . being turn around to an axes to ease its contact with the microphone , under this situation the tuning of the guitar can be done taking as a reference the sound being t ans it through the amplification when the timing fork which is in contact with the microphone is touched.
