Description

The utility model relates to the field of musical instruments and can be used to change the pitch of guitar strings.

Known devices for changing the pitch of the strings of a string instrument: RU 2197756 C2, 27.01.2003. US 6686584 B2, 03.02.2004. US 5359144 A, 25.10.1994. SU 1730670 A, 30.04.1992. GB 2091927 A, 04.08.1982. FR 2537317 A, 06/08/1984. DE 1597028 B2, 26.06.1975.

These devices have the following various disadvantages.

RU 2197756 C2, 27.01.2003 has insufficiently smooth movement of the device, when the device passes the initial stable position, when the lever performs the transition, from the increasing pitch of the selected strings to the lowering position of the selected strings.

US 6686584 B2, 02/03/2004 has insufficient smooth movement of the device, when the device passes the initial stable position, when the lever performs the transition, from increasing the pitch of the selected strings to the lowering position of the device, and does not have sufficient opportunities to adjust the smooth passage of the tremolo mechanism to the initial stable position, which leads to a violation of the smoothness of movement, and does not have sufficient opportunities to adjust the best rolling of the tremolo mechanism, improving the ability to lower the tuning of the selected strings, we get a deterioration in the ability to increase the tuning of the selected strings, if we improve the ability to increase the tuning of the selected strings, then we get a deterioration in the ability to lower the tuning selected strings.

US 5359144 A, 10/25/1994 has an unstable position of the device if its base is not supported on the instrument deck, and with this setting of the device, the strings and springs of the spring element taking into account the string tension are in equilibrium, but if on any or any either by pulling the strings with the fingers of the left hand, this balance is disturbed and the tuning of the other strings changes, and, therefore, at the moment of pulling the strings with the left hand, it is impossible to play the exact note on the other string at the corresponding fret.

If the device is in a position in which its base is supported on the instrument deck and this position does not change when pulling the strings with the left hand, then the disadvantage associated with an unstable position of the device, which manifests itself when performing pulling the strings with the left hand in changing the tuning of those who are not involved in pulling up strings, is absent, but another appears - the lever cannot change the tension of the strings in the direction of increase.

The closest in terms of the set of essential features to the claimed utility model of the tremolo mechanism, and adopted as a prototype is a device for changing the pitch of the strings of a stringed musical instrument according to the invention to patent RU 2197756, IPC G10D 3/14 (2000.01), publication 27.01.2003 Bull. No. 3).

There is a known device for changing the pitch of the strings of a stringed musical instrument, containing a base with sills for supporting the strings and devices for fastening and fine tuning each string and a spring for balancing the tension force of the strings, the base is made of two parts located on top of each other and one side pivotally connected to each other the other, with the upper part made in the form of a frame, and the saddles for supporting the strings and the fastening device and fine tuning of each string are located on the lower part, while the upper part is made in such a way that the saddles for supporting the strings and the fastening device and fine tuning each string pass through the inner hole of the frame, and the entire lower part of the base is larger than this hole. The springs for balancing the tension of the strings are fixed at one end, respectively, on both parts of the base and have different tension regulators. Adjustable stops are installed on the top of the base. This makes it possible to eliminate the following disadvantages. This is an unstable position of the device, if its base does not have a support on the soundboard of the instrument, which manifests itself when performing bends (string lifts), strings that do not participate in a bend (string lifts) lose their tuning accuracy and at this moment it is impossible to extract accurate notes on the corresponding frets, and if the base of the device is supported on the soundboard of the instrument, then in this case the problems associated with the loss of tuning accuracy disappear, but the device does not have the function of changing the tension of the strings with a lever in the direction of increasing, that is, to increase the stability of the tuning of the strings when playing bends (string suspenders). (see the description of the invention to patent RU 2197756, IPC G10D 3/14 (2000.01), publication 27.01.2003 Bull. No. 3).

The disadvantage of this device is the violation of the smooth passage by the device of the initial stable position from the state when the lever performs a transition from the position of the device increasing the tuning of the selected strings to the position of lowering the tuning of the selected strings. At the moment of contact of the base with the sills to support the strings and fastening devices and fine-tune each string and frame, which acts as a stabilizer of the device in the initial stable position, a shock occurs between the base and the frame, which disrupts the smooth movement of the device, and is transmitted to the strings, and becomes audible ...

Also close in the totality of essential features to the claimed utility model is the tremolo mechanism according to the invention to US patent 6686524, IPC G10D 3/00 (20060101) publication 03.02.2004.

String tremolo is widely known and is often found in guitars. The tremolo block increases and decreases the tension on the strings of the stringed instrument to make the instrument sound impressive. An object of the present invention is to provide a tremolo unit for a stringed instrument that minimizes detuning, allows easy and accurate tuning of strings, and does not make the player feel uncomfortable while playing.

To achieve the above and other objects and in accordance with the object of the present invention, there is provided a tremolo applied to a stringed instrument having a base plate and a plurality of strings. The base plate has a top surface and a rear surface and is hingedly supported by the body. The front end of each string is supported by the neck of the fretboard and the rear end of each string is supported by the top surface of the base plate. The tremolo block allows the base plate to rotate in response to manipulation of the tremolo arm. The tremolo unit includes a tremolo unit, a base, an engaging section, a movable element, a first spring and a second spring. The tremolo unit extends vertically from the back of the baseplate into the enclosure space and pivots with the baseplate. The tremolo unit has a hooked portion at its distal end. The base is located at the back of the case. An engaging portion is formed at the rear of the base and opens to the rear. The movable element is disposed with the possibility of detachment in the engagement area. The moving member moves between an engaging position in which the moving member engages with the engaging portion and a waiting position in which the moving member is separated from the engaging portion. The first spring connects the base to the tremolo block and pushes the tremolo block forward from the string tension. The clamping force of the first spring is adjustable. The second spring connects the base to the movable element and pushes the movable element towards the engaging position. In the normal state, the second spring holds the moving element in the engaged position. When the tremolo unit stops or pivots forward, the moving element is held in the engaged position by the pushing force of the second spring. When the tremolo unit is pivoted backward, the moving member moves from an engaging position to a waiting position by contact between the moving member and the hook portion. (See the description of the invention to US patent 6686524, IPC G10D 3/00 (20060101) publication 03.02.2004).

The disadvantages of the known tremolo mechanism are:

These are insufficient possibilities of adjusting the smooth passage of the tremolo mechanism to the initial stable position, when the tremolo mechanism, using the lever K, moves from the position of increasing the tuning of the selected strings to the position of lowering the tuning of the selected strings.

This disadvantage is due to the fact that there is a sharp, and with a large shoulder of application of force, the hook 40 is stationary in anticipation of engagement, to perform its function of stabilization, stabilizing part 90, when the lever K is used to move the tremolo mechanism from the position of increasing the tuning of the selected strings , to the down position of the selected strings. This disadvantage is particularly pronounced when the springs 75 of the spring-loaded string-sensitive tremolo element are adjusted to balance the string tension, that is, when the springs 75 resist the string tension as much as possible, and therefore the load on the spring 80 of the stabilizing part is minimal. This drawback leads to a violation of the smoothness of movement of the tremolo mechanism, from the position of increasing the tuning of the selected strings, to the position of lowering the tuning of the selected strings, when passing the initial stable position, that is, it leads to a deterioration in the smoothness of the vibrato performance.

This disadvantage gradually decreases when the tension of the springs 75 of the spring, taking into account the string tension of the element of the tremolo mechanism, is reduced, but then the disadvantage of the increasing difficulty of performing the tremolo mechanism, using the lever K, increasing the tuning of the selected strings, decreases, and the springs 80 of the stabilizing part do not participate in the movement of the selected strings increasing the pitch of the selected strings.

This is an insufficient opportunity to adjust the best rolling of the tremolo mechanism, since the springs 80 of the stabilizing part of the device, which holds the device from deviations from the initial stable position, when performing string lifts with the left hand, do not have their own separate tension regulator.

Insufficient ability to adjust the best rolling tremolo mechanism manifests itself as follows.

If the springs 75 of the spring-loaded, string-tensioned tremolo element are adjusted so that the tension of the strings and the tension of the springs 75 are in equilibrium, then when the lever K is used to lower the pitch of the selected strings, the musician will experience the maximum resistance of the springs 75, since they are stretched to the maximum strong, and the springs 80 of the stabilizing part, since the load on these springs, in the initial stable position, with this setting of the springs 75 is absent, and there is no spring tension regulator 80 in this device. If there was such a regulator, then it would be possible to adjust the tension of the stabilizer springs 80 to the minimum necessary to keep the device in balance, for a given set of strings, and this option for tuning the tuning of the strings, when the musician pulls the selected strings with his left hand, to the height selected by him tone . Consequently, the adjustment of the springs 75 of the spring, taking into account the tension of the strings of the element of the tremolo mechanism in equilibrium with the strings, reduces the possibilities of the tremolo mechanism, when performing lowering of the tuning of the selected strings, and degrades the rolling characteristics of the tremolo mechanism in the initial stable position, and is not adjustable, since the tension regulators of the springs 80 of the limiter no. It is impossible to solve this adjustment by the selection of 80 springs, since there are many different sets of strings with different string gauges, and different anchors in strings of the same calibers from different manufacturers, and different alloys, from which the anchors and braiding of strings are made, and musicians use different tuning options for the instrument , and all these different variations of different settings, different sets of strings, will create different tension forces on the strings, and therefore require different spring tension of the springs 75 of the spring-based tremolo mechanism element, which is tuned to keep the tremolo mechanism in an initial stable position, when playing, for example, pulling up any string one tone. Any thicker or stiffer string from another set of thicker or stiffer strings, when pulled one tone, will more drastically change the ratio of the sum of the string tension forces, against the counter force of the springs 75 of the spring-loaded string-tensioned tremolo mechanism element, and, hence, it will require a greater force of the holding springs 80 of the stabilizing part. If the springs 80 restrain, with this setting, the tremolo mechanism is in its initial stable position, when performing a pull-up on any string from a set of thicker or stiffer strings by one tone, then when installing less thick or less stiff strings, you will have to adjust the springs 75 of the spring taking into account the tension of the strings of the element of the tremolo mechanism is different, since it is already necessary for this set of strings, but the springs 80 remained the same, and their tension remained the same, and, therefore, the force of their resistance to the movement of the tremolo mechanism remained the same, when performed by the tremolo mechanism, using the lever K, lowering the tuning of the selected strings, when the tremolo mechanism leaves the stable equilibrium position, and, therefore, the tremolo mechanism, when installing less thick or less rigid strings, of course, will maintain stability in the initial stable position, when performing string pulls to a given the musician's pitch, but when lowering the pitch of the selected strings, sop The rotation of the springs 80, for a given set of less thick or less stiff strings, and a given tuning of the strings, will be unreasonably strong. This will worsen the rolling of the tremolo mechanism when lowering the tuning of the selected strings, and will make it difficult, with a given setting of the springs 75, of the spring-loaded, string-tensioned tremolo mechanism element, the tremolo mechanism, using lever K, to lower the tuning of the selected strings.

If the springs 75 of the spring, taking into account the string tension of the element of the tremolo mechanism are adjusted in such a way that the tension of the strings is stronger than the tension of the springs 75, that is, the tension of the springs 75 is weakened, but the tremolo mechanism does not leave its initial stable position, restrained by the stabilizing part, by the tension of the springs 80, with the performance of string lifts with the left hand, to the tuning height adjusted by the musician, then part of the load from the tension of the strings on the springs 75 will be transferred to the springs 80 of the stabilizing part. In this case, the execution of the tremolo mechanism, with the help of the lever K, lowering the tuning of the selected strings will become easier, since the influence of the springs 80 of the stabilizing part counteracting in this movement will decrease, since part of the load of the tension of the springs 75 of the spring element taking into account the tension of the strings has been transferred to them mechanism of tremolo, opposing the tension of the strings, and the resistance of the springs 75 will decrease, since with this setting they are less tightly tensioned, but in this case the musician, when performing with the lever K, increasing the tuning of the selected strings, will experience increased resistance from the tension of the strings, so as the springs 75 of the spring-loaded string-tensioning element of the tremolo mechanism, which, prior to release, took on the entire tension of the strings, to find the device in an initial stable position, fully opposing the tension of the strings, are now tensioned less strongly, and therefore their resistance to the tension of the strings decreased, and, consequently, at If the tuning of the selected strings is out of tune, it will be necessary to increase the force of the musician's influence on the lever K, since the stabilizing part 90 is fixed in a position corresponding to the initial stable position of the tremolo mechanism, and when the tremolo mechanism increases the tuning of the selected strings using lever K, it remains in place of fixation, and has no effect on that part of the tremolo mechanism, which is involved in increasing the tuning of the selected strings, and in this case, only the springs 75 of the spring element of the tremolo mechanism, taking into account the string tension, act against the tension of the strings. This will impair the rolling of the tremolo mechanism when increasing the tuning of the selected strings, and will make it difficult, with this setting of the springs 75, of the spring tension-taking element of the tremolo mechanism, the tremolo mechanism, using the lever K, to increase the tuning of the selected strings.

Also close in the totality of essential features to the claimed utility model is the tremolo mechanism according to the invention to US patent 5359144, IPC G10D 3/00, published 10/25/94).

A device is known for changing the pitch of several strings of an instrument containing a neck with a head, a deck and several strings stretched between the head and a filly on the top surface of the deck.

The device allows you to independently change the pitch of the selected string to one of several defined discrete pitches. It contains a filly attached rotationally to the top surface of the soundboard for fixing the lower ends of the strings. The filly can be turned backward, increasing the tension and pitch of each string, and forward, decreasing them. The filly contains individual adjusting mechanisms designed to be fastened with an adjustable tension on the lower end of each individual string. Each tuning element contains a front segment, the upper surface of which is located on the top surface of the deck, and the rear is located transversely.

The rear segment contains a front support part rotationally connected to the front segment, to which the rear clamping block is slidably moved. This block is pressed against the back segment by the element. The lower end of the string is stretched over the upper and rear surfaces of the anterior segment, between its posterior surface and the anterior surface of the clamping block. Between the filly and the body of the instrument there is a spring element that takes into account the tension of the strings, which establishes a constant tension for several strings, despite the tension of the string, the pitch of which changes (see the description of the invention to US patent 5359144, IPC G10D 3/00, publication 25.10.94. ).

The disadvantages of the known device are: If the device is in a position in which its base is not supported on the soundboard of the instrument, then the strings and springs of the spring element taking into account the string tension are in equilibrium, but if any or any strings are pulled by fingers left hand, then this balance is disturbed and the tuning of the remaining strings changes, and therefore at the moment of pulling the strings with the left hand, it is impossible to play the exact note on the other string at the corresponding fret.

If the device is in a position in which its base is supported on the instrument deck and this position does not change when pulling the strings with the left hand, then the disadvantage associated with an unstable position of the device, which manifests itself when performing pulling the strings with the left hand in changing the tuning of those who are not involved in pulling up strings, is absent, but another appears - the lever cannot change the tension of the strings in the direction of increase.

The essence of the claimed utility model is that a tremolo mechanism for a guitar, containing a base, 3 saddles for fastening and fine tuning of each string, a handle 6, height adjustment screws 7, adjustment screws 4, springs 15, 16 for balancing the tension of the strings and adjusters 13, 14 tensioning the springs, while the base is made of pivotally connected outer 1 and inner 2 parts, the outer part of the base is made in the form of a frame, the handle 6 is located on the inner part of the base, the saddles 3 of fastening and fine tuning of each string are located on the inner part of the base and pass through the frame hole, the height adjustment screws 7 are installed in the frame, and the adjustment screws 4 are installed on the inner part of the base behind the saddles 3 for fastening and fine tuning each string, according to the useful model, the tremolo mechanism for guitar additionally contains a sustain block 9 fixed on the inner part of the base and fixed on keel frame 8, made with the possibility of abutment in dr y into the other through the gasket 18, and the brackets 11, 12 for fastening the springs, the outer and inner parts of the base are pivotally connected in the front part of the base by means of the pivot axis 17 and are made with the possibility of abutting each other when the inner part of the base is rotated around the pivot axis, when In this case, some springs 15 for balancing the tension of the strings are fixed with some ends on the keel 8, and with the others on the same bracket 11 with spring tension regulators 14, and other springs 16 are fixed with some ends on the sustain block 9, and others on another bracket 12 with a regulator 13 spring tension.

The features common to the prototype are:

Outer frame, base with straps for supporting the strings, and devices for fastening and fine tuning each string, tuning screws, tuning screw frame, handle, sustain block, stops, external spring bracket, internal spring bracket, keel, adjusting screws, springs, adjustment screws heights.

The hallmarks of the tremolo mechanism are:

The stabilizing element is useful transferred to the front part of the tremolo mechanism, to the area of the articulated joint on the pivot axis 17, and is made with a minimum arm of interaction between the parts of the base, the outer frame 1 and the inner arm 2, which increases the smoothness of the interaction of the inner arm 2 with the outer frame 1, when performing handle 6 of the transition from the increasing tuning of the selected strings of the position of the tremolo mechanism to the lowering.

A keel gasket 18 is installed, between the keel 8 and the sustain block 9, which, without reducing the rigidity of the stop of the lower front surface of the inner arm 2 to the upper front surface of the outer frame 1, additionally increases the smoothness of the interaction of the inner arm 2 with the outer frame 1, when the handle 6 performs the transition from the high pitch of the selected strings to the low position of the tremolo mechanism.

This tremolo mechanism allows you to independently change the pitch of the selected strings.

This eliminates the following disadvantages:

This is a violation of the smoothness of the movement of the device when the device passes the initial stable position, when the lever performs the transition from the increasing pitch of the selected strings to the lowering position of the device. At the moment of contact of the base with the sills to support the strings and attachment devices and fine-tune each string and frame, when the device passes the initial stable position, for further execution of the device for lowering the tuning of the selected strings, a shock occurs between the base and the frame, which disrupts the smooth movement of the device, and transmitted to the strings, and becomes audible, and violates the smoothness of the vibrato performance (see the description of the invention to patent RU 2197756, IPC G10D 3/14 (2000.01), publication 27.01.2003 Bull. No. 3).

This is an insufficient ability to adjust the smooth passage of the tremolo mechanism of the initial stable position, which leads to a violation of the smoothness of movement, that is, to increase the smoothness of the vibrato performance. (See the description of the invention to US patent 6686524, IPC G10D 3/00 (20060101) publication 03.02.2004).

This is an insufficient opportunity to adjust the best rolling of the tremolo mechanism, that is, to improve the rolling of the tremolo mechanism, increasing the depth and smoothness of the tremolo mechanism, and, consequently, to increase the smoothness and depth of the vibrato performance. (See the description of the invention to US patent 6686524, IPC G10D 3/00 (20060101) publication 03.02.2004).

This is an unstable position of the device if its base does not have support on the instrument deck, which is manifested when pulling the strings with the left hand, a violation of the tuning of the strings that are not involved in pulling up, and if the base of the device is supported on the instrument deck, but in this case not has the function of changing the tension of the strings with a lever in the direction of increasing, that is, to increase the stability of the tuning of the strings when pulling the strings. (see the description of the invention to US patent 5359144, IPC G10D 3/00, publication 25.10.94).

The essence of the useful model of the tremolo mechanism is illustrated by drawings, where: in Fig. 1 shows a useful model of a tremolo mechanism for a guitar, top view; in fig. 2 - the same, bottom view; in fig. 3 - the same, side view.

A useful model of a tremolo mechanism for guitar contains an outer frame 1, an inner arm 2, saddles 3, for adjusting, fixing and fine tuning each string, tuning screws 4, a frame of tuning screws 5, handle 6, height adjustment screws 7, keel 8, sustain block 9, stops 10, bracket for external springs 11, bracket for internal springs 12, spring adjustment bolt 13, adjusting screws 14, external springs 15, internal springs 16, pivot axis 17, keel gasket 18, flat spring 19, while the base is made of two parts located on top of each other and one side pivotally connected to each other using a pivot axis 17, while the upper part is made in the form of an outer frame 1, which serves to maintain the mechanism of the initial stable position when performing string suspenders with the left hand, and saddles 3 for maintenance, fastening, and fine tuning of each string are located on the lower part of the base of the inner arm 2, and the upper part of the outer frame 1 is made that in such a way that the saddles 3 for support, fastening, and fine tuning of each string pass through the inner hole of the outer frame 1, and the lower part of the base, the inner shoulder 2 is smaller than the outermost frame, and when turning on the pivot axis abuts against the upper surface of the front face of the outer frame with the lower surface of its front face, in a position corresponding to the initial stable position of the tremolo mechanism. The rotation, performed on the pivot axis with the handle 6, and made to increase the tuning of the selected strings, is made only by the lower part of the base, the inner shoulder 2, the upper part of the base, the outer frame 1 does not take part in this movement, and remains motionless in the initial position, the turn on the lowering of the tuning of the selected strings, performed with the handle 6, is made by both parts of the base together, relative to the stops 10. The external springs 15, intended to keep the device in an initial stable position when performing string suspenders with the left hand, are fixed with one ends to the outer frame 1 through the keel 8, the other ends are fixed on the bracket of the external springs 11, and have their own tension adjusters, adjusting self-tapping screws 14. The inner springs 16, designed to balance the tension of the strings, are fixed at one end on the inner shoulder 2, through the sustain block 9, with the other ends fixed on the bracket of the inner springs 12, and have their own tension regulator, spring adjustment bolt 13. The handle 6 is fixed with a threaded connection on the bottom of the base of the inner arm 2. On the top of the base of the outer frame 1 there are height adjustment screws 7. This tremolo mechanism allows you to independently change the pitch of the selected strings.

A useful model of a tremolo mechanism for an electric guitar works as follows:

With the guitar strings tuned, make the following adjustments. Adjusting self-tapping screws 14, using the bracket of the external springs 11, adjust the tension of the external springs 15 connected with the keel 8 to the upper part of the base of the outer frame 1, slightly larger than the lower part of the base, the inner shoulder 2, so that the upper part of the base, the outer frame 1, is pressed against the instrument deck with the height adjustment screws 7, while the spring adjustment bolt 13, using the bracket of the internal springs 12, adjust the tension of the internal springs 16 attached to the lower part of the base to the internal arm 2, using the sustain block 9, so that the lower surface of the front part of the internal arm 2 pressed against the upper surface of the front part of the base of the outer frame 1, while the external springs 15, and the internal springs 16, are tensioned so that when performing string suspenders with the left hand, at an interval selected by the musician, the tremolo mechanism does not independently deviate from the initial stable position. In this case, the handle 6, fixed with a threaded connection on the lower part of the base of the inner shoulder 2, can make the desired change, both in the direction of lowering and in the direction of increasing the tuning of the selected strings. As soon as the musician stops using the handle 6, the tremolo mechanism automatically returns to its initial stable position.

The claimed utility model eliminates the shortcomings of the prototype by increasing the smoothness of movement of the tremolo mechanism, when the tremolo mechanism passes the initial stable position, when the handle transitions from the increasing pitch of the selected strings to the decreasing position of the tremolo mechanism, increasing the ability to adjust the smooth passage of the tremolo mechanism to the initial stable position, increasing the possibilities tuning the best rolling of the tremolo mechanism, increasing the stability of the tremolo mechanism when pulling the strings, that is, improving the smoothness and depth of rolling of the tremolo mechanism, and, therefore, increasing the smoothness and depth of the vibrato performance, and increasing the stability of the strings when performing the pulling of the strings.
