TECHNICAL FIELD

[0001] The present disclosure relates to the field of musical instruments. More particularly, the present disclosure relates to a system for fastening strings of a stringed instrument.

BACKGROUND

[0002] The background description includes information that may be useful in understanding the present system. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed system, or that any publication specifically or implicitly referenced is prior art.

[0003] Tuning of stringed musical instrument or lute instrument such as a guitar can be achieved either by increasing or decreasing the tension on a given string of the instrument, thereby raising or lowering, respectively, the pitch of the string. The other type of string tuning is referred to as intonation or string length tuning, which is accomplished by altering the distance between the points at which a given string contacts the bridge and nut elements of the instrument. Lute instrument incorporates a bridge and nut assembly to engage the two ends of the strings of the instruments. Tuning of the strings is done by varying the tension in the strings between the nut and the bridge.

[0004] Because of the frequent tendency of stringed instrument players to bend strings in order to produce a desirable sound, it is important that such bending produce little or no effect in the strings. In other words, there should be little or no cross talk between the strings, even when very strong bending operations are occurring.

[0005] Bending of the string or applying tension on the string, produces force at the engagement points of the strings (i.e. the bridge and the nut), which causes the strings to slide within the slots of bridge and nut. The moment or tension may break the strings if the tension or moment in the strings is not countered.

[0006] The pivot axis about which the bridge pivots has high friction. High friction prevents the bridge from coming back to perfect neutral position when force on the bridge (arm of bridge) is removed. The friction can be minimized by either having a knife edge pivot or by using bearings. Knife edge tends to wear over time and becomes blunt, thereby increasing friction and failing to operate as intended. As force is applied to the arm and the bridge lifts or depresses around the pivot. This motion increases or decreases the string tension resulting in pitch change of the sound produced by the string. As the tension between the end points changes it causes the strings to slide at the support points, namely the nut and the saddles. On removing force from the arm, the tension on the strings returns to balanced condition yet due to friction at the end points, the strings are unable to return to original balanced position hence losing tuning.

[0007] During clamping of strings of the instrument at the nut, if any deflection or bending of the strings occurs at the nut and its clamp, the tuning of the instrument will get affected and the strings can no longer be in tuned.

[0008] Patent document number US4549461 discloses a fine-tuning apparatus which functions as the bridge element of a stringed instrument. The fine-tuning apparatus includes a base element and a series of fine-tuning elements, one for each string. Each fine-tuning element includes a forward block element and a rear block element which is rotatable relative to the forward block element. A string of the musical instrument makes critical contact with the fine- tuning apparatus at point on the rear block element and maintains surface contact with the rear block element as the surface slopes downwardly and rearwardly from the bridge critical contact point, until the point where the string is clamped against surface. Means are provided for adjusting the rotatable position of the rear block element relative to the forward block element, which results in a change in the tension of the string and hence the fine tune of the string

[0009] The cited patent document provides an apparatus for fine tuning stringed instrument which includes a floating type bridge for countering the bending of the strings. Besides, it does not cater to limit the high friction at the pivot point of the bridge while floating and does not provide any means for adjusting the height and intonation of the strings. Also, sliding of the strings at the end point causes loss in tuning. Further, the bridge has no locking means to lock it at a desired angle.

[00010] There is, therefore, a need to provide a system for fastening strings of a stringed instrument having a bridge that can be used as a stationary as well as floating type bridge and can be locked at a pre-defined angle, which further provides clamping of strings at the nut and the bridge and also provides tension, height and intonation adjustment of the strings.

Also, as used in the description herein, the meaning of“in” includes“in” and“on” unless the context clearly dictates otherwise.

[00057] FIGs. 1A to ID, illustrate exemplary perspective views and side views of a bridge unit of the proposed system, in accordance with an embodiment of the present disclosure.

[00058] According to an embodiment, bridge unit 100 (also referred to as bridge 100, herein) of the proposed system can include a bearing support 102 (also referred to as a bearing support base 102, herein) mounted on a top surface of a stringed instrument body (not shown in figure) positioned on the top surface of the stringed instrument in line with a neck of the stringed instrument, a base plate 104 coupled to the bearing support 102 and parallel to the top surface of the stringed instrument body, said base plate 104 can include a plurality of string anchor means 106 (also referred to as saddles 106, herein) to engage one end of the plurality of strings 101 (also referred to as strings 101, herein)of the stringed instrument, and a locking base 108 coupled to the base plate 104 to facilitate the locking of the bridge unit 100 at a pre-defined angle.

[00059] In an embodiment, the base plate 104 can be coupled between bearing supports, namely 102-1 and 102-2 (collectively referred to as bearing supports 102, herein), and parallel to the top surface of the stringed instrument.

[00060] In an embodiment, a locking shaft 110 can be fastened in a vertical hole provided on the base plate 104 near the locking base 108 side and configured to freely rotate in the vertical hole.

[00061] In an embodiment, a lever 112 can be coupled to the locking shaft 110 to enable the rotation of the locking shaft 110 in the vertical hole of the base plate 104. In an exemplary embodiment, a locking shaft plate 114 can be coupled to a top surface of the vertical shaft 110 by a shaft nut 116, but not limited to the likes. Further, the lever 112 can be coupled to the locking shaft plate 114, parallel to the base plate 104 in the direction of a first axis, to enable the movement of the locking shaft 110. The first axis extending parallel to the top surface of the body of the stringed instrument, and in the perpendicular direction of the strings 101.

[00062] In an embodiment, bearings 118 can be configured between the base plate 104 and the bearing support 102, which can be clamped in a groove of the bearing support 102 by a bearing clamp 142 and bearing clamping screw 120, enabling the movement of the base plate/bridge unit about the first axis. In an exemplary embodiment, the lever 112 can facilitate the movement of the bridge unit 100 about the first axis for adjusting the tension of the strings 10 las per convenience and thereby varying the pitch of the instrument.

[00063] In an embodiment, the rotation of the locking shaft 110 by the movement of the lever 112 can enable the locking shaft 110 to engage with the locking base 108, which can prevent the movement of the bridge unit 100 about the first axis and lock the bridge unit 100 at the pre-defined angle. In an exemplary embodiment, rotation of the lever 112 towards a direction away from the first axis can enable the locking shaft 110 to engage with the locking base 108.

[00064] In an embodiment, the locking of the bridge unit 100 corresponds to a stationary or rigid bridge. In an embodiment, unlocked bridge unit corresponds to a floating bridge unit, where the bridge unit is free to rotate about the bearing along the first axis, enabling the variation in the tension of the strings 101 of the stringed instrument.

[00065] In an embodiment, the bridge unit 100 can be configured with a spring 122 to counter the moment produced due to the tension exerted by the strings 101 of the stringed instrument when tuned to pitch. In an embodiment, the spring 122 produces a force countering the tension exerted by the strings 101 and can facilitate bringing the bridge unit into equilibrium state (moment produced due to the strings equals the compression or expansion of the spring). At the equilibrium state, any force applied to the lever 112 in order to lift or depress the bridge unit 100 can momentarily change the balance point. In an exemplary embodiment, the bridge unit can be configured with a plurality of springs to counter the moment of the strings 101.

[00066] In an exemplary embodiment, a block 124 (also referred to as a bridge block 124, herein) can be coupled to the base plate 104 and the bearing support 102 for coupling the spring 122 to the bridge unit 100.

[00067] In an embodiment, the one end of the strings 101 can be clamped at the plurality of string anchor means, which can prevent the deflection of the one end of the strings 101 over the plurality of string anchor means 106.

[00068] In an exemplary embodiment, the one end of the strings 101 can be engaged with the plurality of string anchor means 106 by a string clamping screw 126, but not limited to the likes.

[00069] In an embodiment, the spring 122 can be configured with a spring compression adjustment wheel 128 (also referred to as wheel 128 or spring compression adjuster, herein) to adjust the compression of the spring 122. In an exemplary embodiment, a screw mount 130 can be fastened to the body of the instrument, such that rotation of the wheel 128 threaded in the screw mount 130 produces a linear motion of a screw shaft 140, parallel to the strings 101 and thereby the adjustment of the compression of the spring 122. In an exemplary embodiment, the screw shaft 140 can be configured in between the spring 122 and the screw mount 130.

[00070] In an embodiment, the plurality of string anchor means 106 can be configured with a plurality of height adjustment means 132 to facilitate the adjustment of the height of the strings 101 associated to it. In an exemplary embodiment, the plurality of height adjustment means 132 can include a height screw 134 (also referred to as height adjustment screw 134, herein), whose rotation can facilitate the adjustment of the height of the strings 101. [00071] In an embodiment, the plurality of string anchor means 106 can be configured with a plurality of string intonation means 136 to facilitate adjustment of intonation of the strings, thereby varying the effective vibrating length of the plurality of strings. In an exemplary embodiment, the plurality of string intonation means can include an intonation screw 138, whose rotation can facilitate the adjustment of the intonation of the string.

[00072] In an exemplary embodiment, the bridge unit 100 can be rotatably coupled to the top surface of the stringed instrument body by a knife edge pivot or a bearing, but not limited to the likes.

[00073] FIG. 2 illustrates exemplary perspective view of the nut unit of the proposed system, in accordance with an embodiment of the present disclosure.

[00074] According to an embodiment, a nut unit 200 (also referred to as nut 200 or nut assembly, herein) of the proposed system can be mounted on a top surface of the stringed instrument body and positioned at a location toward a neck of the stringed instrument. As illustrated, the nut unit 200 can include a plurality of grooves 202-1 to 202-N (collectively referred to as plurality of grooves 202, herein) to accommodate other end (also referred to as a second end) of the strings 101 of the stringed instrument.

[00075] In an embodiment, the nut unit 200 can include a plurality of nut clamps 204 configured on top of the plurality of grooves 202 to enable clamping of the other end of the strings 101 of the stringed instrument at the nut unit, in such a way that the plurality of nut clamps 204-1 to 204-3 (collectively referred to as plurality of nut clamps 204, herein) can prevent the deflection of the other end of the strings 101 of the stringed instrument over the plurality of grooves 202.

[00076] In an embodiment, the plurality of nut clamps 204 can be configured to the nut unit 200 by a plurality of nut clamp screw 206- 1 to 206- 1 (collectively referred to as plurality of nut clamp screws 206, herein).

[00077] In an exemplary embodiment, a tuner can be provided near the nut unit side to enable varying the tension in the strings of the stringed instrument.

[00078] In an embodiment, angle of the nut (or surface of the plurality of grooves 202 of nut) and clamping surface of the plurality of nut clamps 204 can be such that, when the strings 101 are under tension, the strings 101 are always in contact with two surfaces of the plurality of grooves 202 and the plurality of clamps 204. Hence when the plurality of clamps is tightened by the plurality of nut clamp screws 206, the strings 101 can be clamped at the nut unit 200 without any deflection. In an exemplary embodiment, the surface of the nut and the surface of the plurality of nut clamps 204 can have a curvature.

[00079] In an exemplary embodiment, string angle of the strings 101 near a head stock of the instrument can be greater than the angle of the surface of the nut 200, such that the strings 101 remains clamped without any deflection when the nut clamp is tightened.

[00080] It is to be appreciated that while various embodiments of the present disclosure have been described with a fixed number of the plurality of string anchor means, the plurality of nut clamps and the plurality of grooves, the concept of the disclosure can be used for any number of the plurality of string anchor means, the plurality of nut clamps and the plurality of grooves for engaging both ends of the strings of the instrument, depending upon the number of strings, and all such applications are well within the scope of the present disclosure without any limitations whatsoever.

[00081] FIGs. 3A and 3B, illustrate bottom view the bridge unit in an unlocked position and a locked position respectively, in accordance with an embodiment of the present disclosure.

[00082] As illustrated in figures, the locking means of the bridge unit 100 can include a locking base 108 coupled to the base plate 104, a locking shaft 110 fastened in a vertical hole provided on the base plate 104 near the locking base side and configured to freely rotate in the vertical hole, and a lever 112 coupled to the locking shaft 110 to enable the rotation of the locking shaft 110 in the vertical hole of the base plate 104.

[00083] In an embodiment, the rotation of the lever 112 can enable the locking shaft 110 to rotate in the vertical hole provided on the base plate 104. The rotation of the locking shaft can enable engagement of a wedge 302 of the locking shaft 110 near its bottom to engage with a channel 304 of the locking base 108. The engagement of the wedge 302 with the channel 304 can lock the bridge unit 100 and prevent further movement of the bridge unit 100 about the first axis.

[00084] As illustrated in FIG. 3A, the lever 112 is coupled to the locking shaft 110 and oriented in a direction towards the first axis and parallel to the base plate. In an embodiment, the wedge 302 of the locking shaft can disengage with the channel 304 of the locking base 108, when the lever 112 is along the direction of first axis.

[00085] As illustrated in FIG. 3B, the lever 112 can be in a direction perpendicular to the first axis, away from the base plate. In an embodiment, the wedge 302 of the locking shaft can engage with the channel 304 of the locking base, thereby disabling the movement of the bridge unit 100 about the first axis.

[00086] FIGs. 4A to 4C, illustrate the bridge unit in a floating state, in accordance with an embodiment of the present disclosure.

[00087] According to an embodiment, the bridge unit 100 in an unlocked position can correspond to a floating bridge unit, which can enable the movement of the bridge unit about the first axis 402. In an embodiment, moment generated by the strings of the stringed instrument can either be greater or lesser than the moment generated by the spring 122. This can cause the bridge unit to either lift up or lift down.

[00088] As illustrated in FIG. 4A, the bridge unit is in an equilibrium position, wherein the moment generated by the strings equals the moment generated by the spring of the stringed instrument. In an embodiment, the bridge unit can either lift up or dip down once it is in unlocked position, now in order to bring it back into tuning. The wheel (as explained in FIGs. 1A and IB) can be rotated to adjust the compression of the spring, until the bridge unit comes to the same position as that of the locked position. At this position, the bridge unit return into perfect tuning (i.e. locked position and equilibrium position coincides).

[00089] As illustrated in FIG. 4B, the moment generated by the strings of the stringed instrument is greater than the moment generated by the spring. This can cause the bridge unit to lift upwards.

[00090] In an embodiment, the spring 122 can be adjusted to change the moment produced by the spring force and vary this force to bring the bridge unit 100 in to equilibrium state to coincide with the locking position, thereby bringing the bridge unit 100 from a lifted position to the equilibrium position.

[00091] In an embodiment, the wheel (as elaborated in FIGs. 1A and IB) can be rotated clockwise or anticlockwise to increase or decrease the compression in the spring 122, thereby either lifting up or lifting down the bridge unit 100. In an exemplary embodiment, the wheel can be rotated to increase the compression of the spring to counter the moment generated by the strings of the stringed instrument, thereby bringing the bridge unit from the lifted-up position to the equilibrium position. [00092] As illustrated in FIG. 4C, the moment generated by the spring 122 is greater is greater than the moment generated by the strings of the stringed instrument. This can cause the bridge unit 100 to lift downwards.

[00093] In an embodiment, the wheel can be rotated clockwise or anticlockwise to increase or decrease the compression in the spring, thereby lifting up or lifting down the bridge unit. In an exemplary embodiment, the wheel can be rotated to adjust the compression of the plurality of springs, thereby bringing the bridge unit 100 from the lifted down position to the equilibrium position.

[00094] While the foregoing describes various embodiments of the system, other and further embodiments of the system may be devised without departing from the basic scope thereof. The scope of the system is determined by the claims that follow. The system is not limited to the described embodiments, versions or examples, which are included to enable a person having ordinary skill in the art to make and use the system when combined with information and knowledge available to the person having ordinary skill in the art.

[00095] Hence, while some embodiments of the present disclosure have been illustrated and described, those are completely exemplary in nature. The disclosure is not limited to the embodiments as elaborated herein only and it would be apparent to those skilled in the art that numerous modifications besides those already described are possible without departing from the inventive concepts herein. All such modifications, changes, variations, substitutions, and equivalents are completely within the scope of the present disclosure. The inventive subject matter, therefore, is not to be restricted except in the spirit of the appended claims.
