Abstract
A string instrument including a body; a headstock; a neck extending between the body and the headstock; and a plurality of tuning mechanisms retained by the headstock and each having a stem with a tuning end and a connection end. Also included are a plurality of strings each having one end connected to the body and an opposite end connected to a different connection end; and a cover covering each connection end and shaped and arranged to prevent physical access to the opposite end connected thereto.
Description




BACKGROUND OF THE INVENTION




String instruments such as acoustic and electric guitars are widely used both for personal enjoyment and entertainment. Although string instruments generally are a source of enjoyment, the strings employed to produce musical sound occasionally can be troublesome. Ends of the strings are attached to tuning stems which can be rotated to adjust string tension and affect pitch of the instrument. The sharp free ends of the strings are exposed and, therefore, can inflict personal injury when contacted by users of the instrument. In addition, the free ends are somewhat unattractive and thereby degrade the overall appearance of the instrument.




The object of this invention, therefore, is to provide an improved, more attractive string instrument which reduces the potential for personal injury during its use.




SUMMARY OF THE INVENTION




The invention is a string instrument including a body; a headstock; a neck extending between the body and the headstock; and a plurality of tuning mechanisms retained by the headstock and each having a stem with a tuning end and a connection end. Also included are a plurality of strings each having one end connected to the body and an opposite end connected to a different connection end; and a cover covering each connection end and shaped and arranged to prevent physical access to the opposite end connected thereto. The cover prevents inadvertent personal injury by the covered opposite ends of the strings.




According to one feature of the invention, the cover includes a base portion secured to the headstock, and a cap portion movable relative to the base portion between a closed position covering the connection end and an open position providing access to the connection end. The provision of relatively movable cap and base portions permits access to the connection ends of the strings without demounting of the covers from the headstock.




According to another feature of the invention, the cover defines an opening providing passage for the associated string. This feature facilitates tuning of the instrument with the covers in closed positions.




According to a further feature, the cover has a hinge portion connecting the cap portion to the base portion. The hinge portion allows opening of the cap portion while preventing misplacement thereof.




According to an additional feature, the base portion defines the opening. This feature facilitates molding of the cover as an integral unit.




According to yet a further feature, the headstock defines a plurality of holes each receiving one of the stems, and each base portion includes an annular fastener portion received by the hole and surrounding the stem. This feature facilitates assembly of the instrument.




According to still additional features, each cap portion defines an inwardly projecting cylindrical portion arranged to receive the connection end with the cap in its closed position and also defines an engagement surface, and each base portion defines a contact surface projecting from the headstock and fittedly engaging the engagement surface with the cap in its closed position. During closure of the cover, the contact and engagement surfaces guide the cylindrical portion onto engagement with the stem thereby securing the cap in its closed position.




According to further useful features, each hole in the headstock defines a shoulder surface formed by a counter-bore, and the annular fastener portion is formed by a plurality of flexible legs each defining a locking tab portion for engaging the shoulder surface. This feature simplifies assembly of the cover by latching the cover to the tuning mechanism.

DESCRIPTION OF THE PREFERRED EMBODIMENT




A string guitar instrument


11


according to the invention is illustrated in FIG.


1


. Included in the guitar


11


is a body


12


and a headstock


13


joined by a neck


14


. A plurality of conventional tuning mechanisms


16


are mounted in the headstock


13


. Each tuning mechanism includes a tuning knob


17


and a tuning stem


18


projecting through the headstock


13


. A conventional tuning gear assembly (not shown) is operably coupled between each knob


17


and each stem


18


. Extending between the body


12


and the headstock


13


are a plurality of strings


19


each having one end


20


connected to a support


21


on the body


12


and an opposite end connected to a different one of the tuning stems


18


. Also included with the guitar


11


are a plurality of accessory covers


23




a


-


23




f


, each mounted on the headstock


13


. The covers


23




a


-


23




c


are shown in a closed position and the covers


23




d


-


23




f


are shown in an open position.




Each cover


23


includes a cap portion


24


and a base portion


25


joined by a living hinge portion


26


as illustrated in

FIGS. 2-7

. The base portion


25


consists of a semi-cylindrical portion


31


, an annular central portion


29


for mounting on a top surface


32


of the headstock


13


, and an annular fastener portion


35


extending below the central portion


29


and received by a hole


36


in the headstock


13


(FIGS.


6


and


7


). Defined by the semi-cylindrical portion


31


is an upwardly projecting bead forming an arcuate contact surface


38


and an opening


39


projecting transversely therefrom. The fastener portion


35


includes three flexible legs


41


having upper ends connected to the semi-cylindrical portion


31


and bottom ends defining outwardly projecting locking tabs


42


.




The cap portion


24


is in the form of a cup


44


with an upper rim defining an arcuate engagement surface


45


shaped to fittedly engage the arcuate contact surface


38


on the semi-cylindrical portion


31


. Also defined by the cup shaped cap portion


24


is an inwardly projecting cylindrical portion


46


shaped to fittedly engage a connection end


48


of the tuning stem


18


as shown in FIG.


7


.




During assembly of the guitar


11


, the fastener portions


35


of the covers


23


are inserted into the holes


36


in the headstock


13


as shown in FIG.


6


. During insertion, the flexible legs


41


are flexed inwardly until the locking tabs


42


reach a counterbore


51


in the hole


36


. At that point, the locking tabs


42


spring outwardly and engage a shoulder surface


52


formed by the counterbore


51


and thereby secure the cover


23


in position on the headstock


13


. Next, the tuning mechanisms


16


are installed by inserting a tuning stem


18


upwardly through each annular fastener portion


35


. A conventional gear assembly (not shown) coupled to a tuning end


50


of the tuning stem


18


then is fixed to a lower surface


55


of the headstock


13


by conventional means (not shown).




Prior to use of the guitar


11


, opposite ends


57


of each string


19


is wound around a stem


18


and inserted through an aperture


58


in a connection end


48


of the stem


18


with its cap


24


in the open position depicted in FIG.


6


. The tuning knobs


27


then are actuated to produce rotation of the stems


18


and tightly wind the opposite ends


57


of the strings


19


around the connection ends


48


. After securement of each opposite end


57


, the associated cap portion


24


of the associated cover


23


is pivoted into the closed position shown in FIG.


7


. The cap portion


24


is retained in the closed position by the frictional engagement between the arcuate contact and engagement surfaces


38


,


45


and between the cylindrical portion


46


and connection end


48


of the stem


18


. Closure of the cap portion


24


is facilitated by the opening


39


in the base portion


25


which allows passage of the string


19


. However, the closed cap portion


24


prevents physical access to the free opposite end


57


of the string


19


. Subsequent fine tuning of the guitar


11


by rotation of the tuning knobs


17


is not hindered by the closed cover


23


.




Obviously, many modifications and variations of the present invention are possible in light of the above teachings. It is to be understood, therefore, that the invention can be practiced otherwise than as specifically described.
