FR2665971A1 - Guitar with reinforced neck - Google Patents

Abstract

The invention relates to a guitar with a reinforced neck comprising an elongated body defining a fingerboard, several frets distributed transversely on the said fingerboard, several tuning pegs mounted on the said elongated body, several strings connected respectively to the said tuning pegs and passing above the said frets. The elongated body of the neck comprises a shell (10) made from a fibre-reinforced plastic material and a core (20) of foam.

Description

The present invention relates to a guitar and in particular the neck

  of a guitar, formed by a reinforced plastic shell and by a core

foam.

  Most conventional guitars are made entirely or partly of wood Wooden guitars are likely to warp in

  an environment that is not completely dry.

  This problem significantly affects the quality of the sound produced, causing the guitar to degrade after a short time. Another problem is the short service life of a wooden guitar which results from the low resistance of the wood. was brought in by making a piece

  hollow in wood to surround a metallic core.

  However, the structure is heavy and requires a

complicated process.

  Figure 1 shows a guitar neck structure which includes a fiber-reinforced plastic shell and a wooden core. This construction presented better robustness and good resistance to humidity. However, the obligation

  machining the wooden core creates a drawback.

  An object of the invention is to create a guitar comprising a neck of improved structure, which is of light weight, resistant to humidity and which

can be easily manufactured.

  In accordance with the present invention, the neck structure of a guitar comprises: an elongated body defining a finger pad, several frets or sillets arranged transversely to the finger pad, several chord pegs mounted on the elongated body , several cords respectively connected to the tuning pegs and kept stretched above the fretsi the improvement consisting in that the elongated body is formed of a shell made of fiber-reinforced plastic and of a foam core. Other characteristics and advantages of the invention

  will be highlighted in the following description,

  made in connection with an exemplary embodiment and with reference to the accompanying drawings in which: FIG. 1 is a perspective view of a neck of a known guitar; Fig 2 is a perspective view of a neck of a guitar according to the invention; - fig 3 is a sectional view taken along line 3-3 of fig 2 and fig -4 is a sectional view made along line

line 4-4 of fig 2.

  With reference to FIGS. 2 to 4, a neck for a guitar constructed in accordance with the present invention comprises an elongated body which is formed by a shell made of fiber reinforced plastic material, surrounded by a core 20 of foam or expanded material The shell 10 has an oblong cross section The upper side of the shell 10 defines a finger pad, on which are arranged several frets, or sillets, 11 provided with notches 111 for the strings, as well as a transverse bar 12, provided also of notches 121 String supports 13 are mounted in an extreme part of the elongated body and tuning pegs 15 are connected to the string supports 13 Ropes 14 are fixed to the supports 13 and are stretched above the shelf fingerboard, the other ends of the strings being attached to a guitar case (not

  shown), which is connected to the handle.

  The shell may be formed of a plastic material reinforced with carbon fibers or glass fibers. The foam core may be formed of ethyl vinyl acetate foam or of another suitable foam. The manufacture of this composite structure is simple and known and is produced by first forming the tubular shell and then forming

  in-situ the foam core in the tubular shell.

  The product formed has a smaller weight than that of the structure shown in fig 1 and it is

more sustainable.

  Of course, the invention is in no way limited

  to the description given above and many

  variations and modifications may be considered

  without departing from the scope of the invention.
