Abstract
ABSTRACT OF THE DISCLOSURE
The present invention relates to a string post for a musical instrument. In some prior art instrument, buttons or other attachments are connected to the instrument head and the strings engage such attach-ments between the nut and the string posts so that the strings are held close to the instrument head. While this increases the pressure between the strings and the nut, there is not always sufficient room to use such attachments and they add an additional expense to the instrument. Accord-ing to the present invention, these problems are solved by providing a novel string post for musical instruments. Briefly, the present string post has a constantly decreasing diameter from the outer end thereof to a first plane virtually at the instrument head and has an increasing diameter from the first plane to a second plane at the instrument head so as to form a curved shoulder at the base of the post between the first and second planes. This construction urges a string wrapped around such a string post toward the instrument head until the last wrap seats against the shoulder at the base of the post, virtually in contact with the instrument head.

Description
1~364744 The pre~ent invention relates to a string post ~or a musical instrument and, more particularly, to a musical instrument string poæt which maximizes the string pressure on the instrument nut.
In a conventional stringed instrument, such as a guitar, bass and the like, a plurality o~ strings extend from a bridge, across the instrument body, and over a neck to the head of the instrument. At the end o~ the neck, the strings pass through grooves in a nut positioned at the intersection of' the neck and the head and are then wrapped around a plurality o~ string posts connected to the head.
A typical string post extends perpendicular to the instrument head and is adapted to be rotated manually to tighten the string wrapped therearound. Rotation of the string post changes the pitch of the string, permitting tuning of the instrument.
In such an instrument, it is important that each string be held down firmly in its associated groove in the instrument nut. In case~ where this is not done, several problems are pre~ented. Initially, i~ the string is not held ~irmly in the groove in the ~ut, it can literally jump out of the groove during playing of the instrument and this would, among other things, change the pitch o~ the string.
Secondly, since the tone sustaining capability of` a string is a direct ~unction o~ the rigidity of lts end point con-nections, the ability of the string to move in the groove in the nut, the nut defining one end point connection, sub-stantially reduces the tone sustaining capability o~ the string below the level which is theoretically obtainable.
In most instruments, no e~ort is made to increase the pressure between each string and the nut over that obtainable simply by extending the string between the instrument bridge and the string post. In some instruments, ~6~t~
buttons or other attachments are connected to the instru-rnent head and the strings engage ~quch attachments between the nut and the string posts so that the strings are held close to the instrument head. While this increases the pressure between the strings and the nut, there is not always suf~icient room to use such attachments and they add an additional expense to the instrument. While the string posts themselves have the capabilit~ o~ substantially affecting the pressure between the strings and the instru-ment ~ut, no attempts have been made heretofore to takeadv~ntage of this capability.
According to the present invention, these problems are solved by providing a novel string post for musical instruments. The present string post urges a string wrapped therearound toward the instrument head, holding the end of each string as close to the instrument head as is practically feasible. This increases the wrap o~ the string ` over the instrument nut, increa~ing the pres~ure o~ the strin~ on the nut, virtually eliminating the possibility of`
khe ~tring mo~ing in or out o~ the groove in the nut. The present string post alæo substantially reduces the ability of the string to vibrate relative to the nut, substantially increasing the tone sustaining capabilities of each string over that obtainable heretofore.
Briefly, the present string poqt ha~ a constantly decreasing di~meter from the outer end thereof to a first plane closely ad~acent (virtually at) the instrument head and has an increasing diameter from the f'irst plane to a second plane at the instrument head so as to form a curved shoulder at the base of the post between the ~irst and second planes. This construction urges a strinæ wrapped around such a string post toward the instrument head until the last wrap seats against the shoulder at the base o~ the 1~69~ 4 post,virtually in contact with the instrument head.
It is therefore an object of the presen~ inven-tion to provlde a string post for musical instruments.
It is a further object of the present invention to provide a musical instrument string post which increases the tone sustaining capabilities of a string.
It is a still ~urther object o~ the present in-vention to provide a musical instrument string post which increases the pressure between a string and the instrument nut.
It i8 another obàect of the present invention to provide a musical instrument string post which elimi-nates the possibility o~ a string moving out of its associ-ated groove in the instr-ument nut.
Still other objects, features3 and attendant advantages o~ the present invention will become apparent to those skilied in the art ~rom a reading o~ the following detailed de~cription of the pre~erred embodiment con-structed in accordance therewith taken in con~unction with the accompanying drawings wherein like numerals designate like parts in the ~everal ~igures and wherein:
Fig~e l~i~ an elevation view o~ a conventional stringed instrument, a sblid body electrlc bass, including a plurality o~ string posts;
Figure 2 is an elevation view o~ the back of the head of the instrument o~ Figure l;
Figures 3A through 3D are side elevation views of prior art string posts; and Figure 4 is a side elevation view o~ a string post constructed in accordance with the teachings o~ the present invention.
Referring now to the drawing~ and, more particu-larly, to Figures 1 and 2 thereo~, there is shown a conven-'74~
tional musical instrument, namely a solid body bass, gener-ally designated 10, including a body 11 and a neck 12, one end o~ which is connected to body 11. Also connected to body 11 is a bridge 13 to which is connected first ends of a plurality o~ strings 14. ~rom bridge 13, strings 14 extend across body 11 and above neck 12. Neck 12 may also include a plurality of ~rets 15, the pitch of each string 14 being changeable by pressing same against one of frets 15.
At the other end of neck 12 is a nut 16 which extends thereacross, perpendicular thereto, nut 16 having a plurality of grooves in the outer sur~ace thereof, one ~or each string 14. Connected to the same end of neck 12 is a head 17 which supports a plurality o~ string posts 18.
String posts 18 extend perpendicular to head 17J typically extending entirely through head 17. F rst ends of posts 18 are on the same side of head 17 as strings 14 and eaah string 14 is adapted to be connected to one of posts 18. As i9 known in the art, the other end of each post 18 ma~ be connected to a worm wheel 19 which engages a worm 20 which is mountèd for rotation relative to the back of head 17 by a con~entional plate 21. Rotation of worm 20 is achieved by means Or a knob 22 connected to one end thereof. Accord-ingly, rotation o~ worm 20 rotates string post 18, permitting the manual tightening of a string wrapped therearound.
Referring now to Figures 3A through 3D, there is ~hown the most popular kypes of string post presently available. In Figure 3A, a ~tr~ng post 25 is generally cylindrical, having a constant diameter from the outer end thereo~ to head 17, and ha~ a hole 26 extending laterally therethrough through which the end of strin~ 14 is extended.
W1th this type o~ string po~t, the turning thereof causes string 14 to be wrapped therearound in a random ~ashion ~ 6fl~7~L4 and thPre is no guarantee that string 14 will be held close to head 17. Furthermore, with this configuration o~ string postJ it is possible for string 14 to slide along the surface o~ post 25 and disengage itsel~ there~rom during use.
With reference to Figure ~B, a string post 27 is shown which is generally similar to string post 25 but ~or a slot 28 extending laterally therethrough, from the outer end thereof, instead of hole 26. As is shown in Figure 3B, this configuration causes the wrapping o~ a string 14 therearound in a random ~ashion, creating the same problems which exist with string post 25.
With reference to Figure ~C, a string post 30 is shown which is generally similar to string post 27 in that a slot ~1 extends laterally therethrough, from the outer end thereof. On the other hand, the opposite ends o~ slot 31 have a countersink, as shown at 32, so as to ~orm a slight ~rvature in the outer surface of post 30. ~his curvature has the tendency o~ centering a string 14 in the area o~
countersink 32, preventing string 14 ~rom slipping off o~
~he end o~ post 30. On the other hand, such countersink also holds the end o~ string 14 spaced by a substantial distance ~rom head 17, thereby minimizing the pressure be-tween string 14 and nut 16.
The string post 34 o~ Figure 3D is a ~urther extension of the concept of string post 30. That is, string post 34 has a slot 35 extending laterally therethrough, ~rom the outer end thereo~, ~ut the diameter o~ the outer surface of post 34 is no longer constant. Rather, the outer diameter of string post ~4 is a minimum hal~ way between the outer end thereof and head 17 and the diameter increases in both directions ~rom this minimum diameter pIane. Such a con~iguration causes the end of string 14 to stay adjacent the midpoint o~ post 34 to prevent string ;47~9L
14 ~rom slipping off of the end thereof~ On the other hand, the same problem exists as with post 30 in that string 14 is held in spaced relationship relative to head 17.
Referring now to Figure 4, there is shown a string post, generall~ designated 40, constructed in accord~
ance with the teachings of the present invention~ String post 40 is of the type which extends perpendicular to head 17 of instrument 10 and is adapted to be rotated manually to tighten a string 14 wrapped therearound. String post 40 also has a slot 41 extending laterally thereacross, from the outer end thereof, ~or receipt o~ string 14. String ~ post 40 is distinguishable from string posts 25, 27~ 30, : and 34 in that it has a constantly decreasing diameter from the outer end thereof to a plane which is positioned closel~
adjacent ~virtually at) instrument head 17. Preferably, the outer diameter of post 40 decreases linearly from the outer end thereof to such plane~ Between such plane and the surface of head 17, the diameter of post 40 increases sli~ltly so as to form a curved shoulder, at 42, at the base o~ post 40, for receipt of the lowermost wrap o~
string 14. At the lower end of shoulder 42, at the surface o~ head 17, the diameter of post 40 remains constant as it extends into and through head 17.
With such a design~ a string 14 wrapped around post 40 is urged toward and virtually or ac~ually into contact with instrument head 17. In fact, as the tension in string 14 i8 increased by rotatin~ post 40, the increased tension causes string 14 to seek the plane of minimum diameter, which is at shoulder 42. Therefore, after the end o~ string 14 is extended into slot 41 and post 40 rotated, it is necessarily true that string 14 will extend downwardly towards head 17, rather than wrapping in a random manner, with the lowermost turn a~ainst shoulder 42.
1~6~79~
By so positioning khe end o~ string 14, the wrap o~ string 14 over nut 16 is maximized~ maxi~izing the pressure between strlng 14 and nut 16. This insures that string 14 will neither move nor vibrate relative to nut 16.
This not only insures that string 14 will not move out of its associated groove in nut 16, but maximizes the tone sustaining capabilities of the strings~
While the in~ention has been describèd with respect to the preferred physical embodiment constructed in accordance therewith, it will be apparent to those skilled ; in the art that various modifications and improvements may be made without departing from the scope and spirit of the invention. Accordingly, it is to be understood that the invention is not to be limited by the specific illus-trative em~odlment, but only by the scope of the appended ~aim;.
