Sentralenhet for elektrisk modulgitar med justerbart halsfeste. Central unit for electric modular guitar with adjustable neck attachment.

Oppfinnelsen angår en sentralenhet hvorpå og utifrå hvilken deThe invention relates to a central unit on which and from which they

deler monteres som tilsammen utgjør en elektrisk gitar.parts are assembled that together make up an electric guitar.

Dagens elektriske gitarer er hygd opp rundt en kropp vanligvis av massivt tre. Instrumentets kvalitet og spillbarhet avhenger av at hals og strengefeste er nøyaktig tilpasset og montert. De aller fleste elektriske gitarene kommer ferdig fra fabrikk som lager dem i store serier. Men idag har de fleste som kjøper disse instrumentene individuelle krav som krever justeringer gjordt av kyndig person. Today's electric guitars are built around a body usually made of solid wood. The instrument's quality and playability depend on the neck and string attachment being precisely fitted and fitted. The vast majority of electric guitars come ready-made from factories that make them in large series. But today, most people who buy these instruments have individual requirements that require adjustments made by a knowledgeable person.

Ofte vil eieren av instrumentet også foreta utskifting av kpmponenter og forandre på kroppen. Dette er blitt en sterk trend og følgelig er det vokst frem en hel industri som tilbyr ekstrautstyr og utbytte-komponenter. Som regel medfører dette at brukeren helt eller delvis demonterer instrumentet i en grad som resulterer i at instrumentets spillbarhet skjelden blir tilfredsstillende etterpå. Often the owner of the instrument will also replace components and change the body. This has become a strong trend and, as a result, a whole industry has emerged that offers additional equipment and dividend components. As a rule, this means that the user completely or partially dismantles the instrument to an extent that results in the instrument's playability being rarely satisfactory afterwards.

Foreliggende oppfindelse går ut på at etter at instrumentet er justert og strengene er oppspent kan all elektronikk skiftes ut og kropps-deler av og påmonteres, uten at instrumentet behøver å justeres på nytt. Sentralenheten er videre utført slik at gitarhalsen kan justeres i forhold til kroppen mens strengene er oppspent. I motsetning til at man normalt må ta av halsen for så å legge imellom eller ta av materiale. Oppfindelsen gjør det også mulig å folde instrumentet sammen for å lette transport, deretter kan instrumentet settes opp igjen uten behov for noen ny justering, knapt finstemming. Forvandlingen kan hurtig utføres av brukeren selv. Oppfindelsen gjør det mulig å bruke standard i handel gitarhalser, strengefester og elektronikk. Brukeren kan uten konsekvenser for instrumentets spillbarhet og uten The present invention is based on the fact that after the instrument has been adjusted and the strings are tensioned, all electronics can be replaced and body parts removed and fitted, without the instrument needing to be adjusted again. The central unit is also designed so that the guitar neck can be adjusted in relation to the body while the strings are tensioned. In contrast to the fact that you normally have to remove the neck in order to insert or remove material. The invention also makes it possible to fold the instrument to facilitate transport, then the instrument can be set up again without the need for any new adjustment, barely fine-tuning. The transformation can be quickly carried out by the user himself. The invention makes it possible to use standard commercial guitar necks, string mounts and electronics. The user can without consequences for the instrument's playability and without

å ha spesiell innsikt bytte ut kroppssidestykkene med selvlagde av en hvilken som helst form. having special insight replace the body side pieces with self-made ones of any shape.

For at disse egenskaper skal oppnås er konstruksjonen utført med en meget stiv metallramme som i den ene enden har en gaffel med en påhengslet halsfestebrakett. Disse har borede og gjengede hull for påskruing av hals, strengefeste, sidestykker og elektronikk. In order to achieve these properties, the construction is made with a very rigid metal frame which at one end has a fork with a hinged neck attachment bracket. These have drilled and threaded holes for screwing on the neck, string attachment, side pieces and electronics.

For å kunne oppnå god stabilitet og gode forhold for strengenes svingninger er det i forbindelsene mellom hals, halsfestebrakett, ramme og sidestykker gode kontaktflater og solide skrueforbindelser. Den hengslede forbindelsen mellom ramme og halsfestebraketten er forsynt med fine passninger og . vil derfor ikke slarke, vris eller forandre stilling annet enn den tilsiktede rotasjon om akslingen. Denne mulighet til rotasjon eller vipping fremkommer idet to låsebolter mellom gaffelen og halsfestebraketten løsnes. Dette gir muligheten til å justere halsens vinkel i forhold til gitarkroppen. In order to achieve good stability and good conditions for the strings' oscillations, there are good contact surfaces and solid screw connections in the connections between the neck, neck attachment bracket, frame and side pieces. The hinged connection between the frame and the neck attachment bracket is provided with fine fits and . will therefore not sag, twist or change position other than the intended rotation about the axle. This possibility of rotation or tilting appears when two locking bolts between the fork and the neck mounting bracket are loosened. This gives the opportunity to adjust the angle of the neck in relation to the body of the guitar.

I rammen er det plasert en justerskrue som brukes til å vippeAn adjustment screw is placed in the frame, which is used for tilting

halsen idet de oppspente strengene forårsaker at hals og halsfestebrakett presses ned mot justerskruens ende. Låseboltene skrus the neck as the tensioned strings cause the neck and neck attachment bracket to be pressed down towards the end of the adjusting screw. The locking bolts are screwed

så til igjen. En sekundær effekt av dette hengslesystemet er at halsen kan foldes 180 grader bak på gitaren. Denne foldingen kan utføres etter at strengefestet er hektet av og uten at strengene slakkes først. Denne siste teknikken er velkjent og forklares ikke nærmere idet det her skal brukes et i handel strengfeste som i seg selv gjør denne avhektingen mulig. see you again. A secondary effect of this hinge system is that the neck can be folded 180 degrees at the back of the guitar. This folding can be carried out after the string attachment has been unhooked and without first slackening the strings. This last technique is well known and will not be explained in more detail, as a commercially available string attachment will be used here, which in itself makes this detachment possible.

Oppfinnelsen skal i det følgende forklares nærmere under henvisning til tegningen, der The invention will be explained in more detail below with reference to the drawing, where

figur 1 viser sentralenheten med den justerbare halsfestebraketten vippet opp, og hals påskrudd. Kroppens sidestykker er skrudd fra. figure 1 shows the central unit with the adjustable neck attachment bracket tilted up, and the neck screwed on. The side pieces of the body are unscrewed.

figur 2 viser sentralenheten delvis snittet og med hals, strenger, strengefeste og pickuper montert. figure 2 shows the central unit partially cut and with the neck, strings, string attachment and pickups mounted.

Sentralenheten består av en ramme 15 med fast gaffel 7»en halsfestebrakett 4»en aksel 10, låsebolter 2 stk. 2 og en justerskrue 8. Disse delene er i metall. The central unit consists of a frame 15 with fixed fork 7" a neck mounting bracket 4" an axle 10, locking bolts 2 pcs. 2 and an adjusting screw 8. These parts are made of metal.

På sentralenheten monteres hals 1 til halsfestebraketten 4 medOn the central unit, neck 1 is mounted to the neck attachment bracket 4 with

skruer 6. Halsen skrus på når halsfestebraketten er åpen. Halsfestebraketten sitter hele tiden fast på gaffelen 7 med akselen 10 slik at dette danner en hengsel. Hengselet lukkes slik at halsfestebraketten 4 hviler ann mot justerskrue 8 som stikker opp fra et gjenget hull i screws 6. The neck is screwed on when the neck attachment bracket is open. The neck attachment bracket is permanently attached to the fork 7 with the shaft 10 so that this forms a hinge. The hinge is closed so that the neck attachment bracket 4 rests against the adjusting screw 8 which protrudes from a threaded hole in

rammen 15«Halsfestebraketten 4 låses i ønsket stilling med låseboltene 2, disse sitter i hull 3 gjenget i halsfestebraketten 4«Spor 5 i gaffel 7 e^for låseboltene 2 slik at disse ikke behøver å skrus helt av. Boringer 13 er for montering av en standard strengefeste her ikke detaljbeskrevet. Gjengede hull 14 er for påbolting av sidestykkene 12 med bolter 20. Sidestykkene vil alternativt, eventuelt istedet bli montert med i sidestykkene fastgjordte bolter der trekkes til med en kileanordning. Etter at strengene 16 er oppspent løsnes låseboltene 2 slik at kraften fra strengene presser halsfestebraketten ned mot justerskruen 8, denne skruen justeres så fra undersiden av rammen 12, se fig.2, slik at halsens vinkel blir slik ønsket. Låseboltene 2 trekkes til deretter. Elektroniske pickups 18 sitter montert i en plate 17 som videre sitter skrudd i gjengede hull 11, platen med pickups kan tas ut sideveis dersom strengene er oppspent, ett sidestykke 12 må da skrus av. the frame 15"The neck attachment bracket 4 is locked in the desired position with the locking bolts 2, these sit in holes 3 threaded in the neck attachment bracket 4"Slot 5 in the fork 7 for the locking bolts 2 so that these do not need to be completely unscrewed. Drilling holes 13 are not described in detail here for mounting a standard string attachment. Threaded holes 14 are for bolting on the side pieces 12 with bolts 20. The side pieces will alternatively, possibly instead, be mounted with bolts fixed in the side pieces which are tightened with a wedge device. After the strings 16 are tensioned, the locking bolts 2 are loosened so that the force from the strings pushes the neck attachment bracket down against the adjusting screw 8, this screw is then adjusted from the underside of the frame 12, see fig.2, so that the angle of the neck is as desired. The locking bolts 2 are then tightened. Electronic pickups 18 are mounted in a plate 17 which is further screwed into threaded holes 11, the plate with pickups can be removed laterally if the strings are tensioned, one side piece 12 must then be unscrewed.
