Definitions

  • the present invention relates to a musical method for keyboard musical instruments and struck strings traditional, such as pianos, as well as a mechanism implementing said method.
  • the mechanism according to the invention is of the type comprising a set of strings each capable of being struck by a hammer operated by a key, each rope being equipped a damper which, in the unsolicited position, is in support on the rope and prevents it from vibrating and which in position stressed, is removed from the rope.
  • the function of the harmonic bar and the strong bar is to remove all the dampers from the strings.
  • the harmonic bar leaves the damper supports accessible to said distal parts of the keys, unlike the strong bar .
  • the invention relates to a mechanism for ensuring that the effect of the forte bar can be interrupted with respect to the notes about to be played while retaining this effect with respect to the notes coming to be played, which mechanism makes it possible to keep in resonance and to keep in the harmonic position arpeggios played in strong position .
  • a mechanism of the aforementioned type is known for example from patent EP-0 271 527 in the name of Denis de La Rochefordière, a mechanism which is schematically represented in FIG. 1.
  • This known mechanism applied to an upright piano, associated with each rope 107 a damper 106 which is subjected to a separable couple of exhaust means, one of which is an exhaust nut 110 associated with a harmonic bar 111, actuated by a harmonic pedal - which is advantageously the pedal of strong, the harmonic position corresponding to the semi-depressed pedal while the strong position corresponds to the fully depressed pedal -, and the other is an exhaust spring 109 depending on the support 104 of the damper 106.
  • the rotation according to F 1 of the harmonic bar 111 causes a displacement of the exhaust nut 110, which urges the exhaust spring 109 with which it is engaged so as to move the damper 106 away from the string 107.
  • a spoon 103 associated with the button 101 and acting directly on the damper support 104 causes, when the button 101 is pressed, the separation of the exhaust means 109, 110 and maintains the damper 106 away from the cord 107; the note vibrates until the button 101 is released and the damper 106 returns to the string 107. The note is then muted while the lower strings continue to vibrate out of sympathy.
  • the object of the invention is therefore to propose a method musical and a pedal mechanism that allow to remedy these disadvantages of the known system.
  • the harmonic bar and the exhausts are capable of returning to engagement, after a key has been pressed and released in the harmonic position, either by total relaxation of the pedal and then very slight depression thereof, or by depression from the pedal to the strong position and then very slight release of it.
  • the mechanism according to the invention comprises a system of linkage that connects the harmonic bar and the sustaining bar in the dual-action pedal.
  • the harmonic bar and the strong bar are each pivotally mounted and slaved to the movement of one of the ends, called “distal”, of a connecting rod, the other end of which , called “proximal”, is animated by a pivoting movement under the effect of a control rod actuated by the mixed pedal.
  • each of the connecting rods is slaved to the pivoting of the same part, called “guignol”, on which the control rod acts.
  • each of the exhausts is a freely mounted part swivels between a stop position against the support associated damper and be an equilibrium position by gravity (corresponding to another stop position against the damper support), i.e. a support position on a interfering part, which is, for example, the end, called “distal", the associated key or the harmonic bar.
  • each of the exhausts is a pivotally mounted part between two positions, elastic means tending to keep or returning said exhaust to one of said positions.
  • each exhaust has two contact zones, one being likely to come in contact with said distal key portion or said spoon and the other being likely to come in contact with said harmonic bar.
  • the mechanism according to the invention comprises a pedal 1 whose general direction X 1 -X ' 1 forms, at rest, an angle of about 30 ° relative to the horizontal, which pedal is mounted pivoting in its center around an axis 2 secured to a vertical support 3 belonging to a grand piano.
  • Pedal 1 supports, at its distal end, that is to say opposite to that actuated by the pianist, one end of a control rod 4, substantially perpendicular to said pedal, and the other end of which is spherical , cooperates with a horn 5 which substantially takes the form of an equilateral curvilinear triangle.
  • the horn 5 has, at the top 5a, bearing on the control rod 4, a cutout 6 substantially at right angles, this form of cutout however not being imperative.
  • the side 51 of the triangle 5, adjacent to said cutout 6 and away from said pedal 1 forms an angle of approximately 45 ° relative to the horizontal and an obtuse angle with the control rod part. 4 outside cutting 6.
  • the horn 5 is articulated, at the level of the other vertex 5b adjacent to said side 51, around an axis 7 integral with the curved top 8a of a horn support screed 8, which has substantially the shape of a right triangle whose the hypotenuse is, at rest, in the extension of said side 51 of the horn 5.
  • the side of said yoke 8 opposite to said curvilinear top 8a is fixed on the bottom 9 of the piano which is horizontal.
  • a post 10 extends perpendicular to the bottom 9 of the piano, on the opposite side to said clevis 8.
  • the mechanism further includes a battery of damper supports, such as 104, each of which corresponds to a key and a rope. We will describe the damper support 104 corresponding to the button 101 and the cord 107.
  • One end of said support damper 104 is connected to the free end of said upright 10 and pivotally mounted thereon, about an axis 12. Au rest, the damper support 104 is horizontal. The other end of the damper support 104 forms a surface stop 54 from which project a pair of ears 55 which support an axis 30 around which is pivotally mounted an exhaust 13 provided with a heel 14, a tapered spout 15 and an abutment surface 56. At rest, the upper zone of the abutment surface 56 is away from the stop surface 54 while the lower area of the abutment surface 56 abuts against the stop surface 54, so that the heel 14 of the exhaust 13 rests practically on the distal end button 101, i.e. on the end of the button opposite to that operated by the pianist.
  • the third apex 5c of the horn 5 supports an axis 16 around which is anchored, pivoting, one of the ends of a connecting rod 19 whose other end is anchored, pivoting, around an axis 40 mounted on a plate drive 47 of a harmonic bar 111.
  • the harmonic bars 111 and strong 112 which are substantially parallel in the situation of Figure 1, are respectively supported by a set 22 of four supports of harmonic bar and a set 23 of four strong bar supports , which sets of supports 22, 23 are pivotally mounted around the aforementioned axis 12.
  • the set of supports 23 conceals the set of supports 22. They are distinct in FIG. 6.
  • An axis 25 crosses the support transversely damper 104 and serves as an anchor at one end a damper rod 26, the other end of which is fixed to a damper 106, at the center of gravity of said damper, the latter being provided with two felt 29a and 29b which are, at rest, in contact with the cord 107.
  • FIG. 3 shows the mechanism according to the invention when the button 101 is pressed (arrow F 2 ), the pedal 1 not being pressed.
  • the hammer (not shown) associated with said key 101 then strikes the cord 107.
  • the distal end of the key 101 by pivoting along F 3 , lifts the heel 14 of the exhaust 13 which pivots about the axis 30 until the upper zone of the abutment surface 56 comes into contact with the stop surface 54; therefore, the exhaust 13 and the damper support 104 behave like a single piece which pivots about the axis 12.
  • the rod 26 is biased upwards (arrow F 4 ) and that, as a result, the damper 106 moves away from the string 107.
  • the note played vibrates thus, until the key 101 is released, the mechanism then returning to the situation in FIG. 2.
  • FIG. 4 illustrates the mechanism according to the invention in the case where the pedal 1 has been slightly depressed, up to the harmonic position (general direction X 2 -X ′ 2 ), while the button 101-is at rest.
  • the pressure exerted on the pedal 1, according to F 5 transmitted, according to F 6 and via the control rod 4, a rotational movement, according to F 7 -F 8 , to the horn 5 around the axis 7 and therefore a upward movement, via the connecting rod 19, of the harmonic bar 111, which came into contact with the spout 15 of all the exhausts such as 13.
  • the configuration of the device, at the time of actuation of the pedal 1, was such that the point of contact between the spout 15 and the harmonic bar 111 was in the plane formed by the axes 30 and 40, so that the exhaust 13 has not pivoted around the axis 30 but has raised, carrying with it the damper support 104 and the rod 26.
  • the same was true for all the other exhausts, which had the effect of taking off all the dampers, such as 106, ropes, such as 107. the rotation of the crank 5 simultaneously caused the displacement upwards via the link 20, the sustaining bar 112.
  • the button 101 If, being in this position, the button 101 is pressed according to F 2 , its distal end urges the heel 14 of the exhaust 13 upwards, resulting in the pivoting of the exhaust 13 around the axis 30 and the separation of the spout 15 from the harmonic bar 111. Then (FIG. 5), if the said button 101 is released, the heel 14, which is no longer subjected to any stress, follows the pivoting downward of the distal end of the key 101 while resting against said key 101, substantially until said key is fully released, and the spout 15 is then adjacent to the harmonic bar 111, along the front face thereof, this is that is, from the side facing the piano keyboard. The damper 106 then returns to the rope 107. All the other dampers remain raised since the return of the damper 106 to the rope 107 results from pressing the button 101, the other buttons having remained inactive.
  • the strong bar 112 caused the damper supports, such as 104, associated with the other exhausts (not “re-armed") to pivot further upwards around the axis 12, so that the spouts , such as 15, exhausts, such as 13, are passed over the harmonic bar 111.
  • all the dampers are in the same plane. From this position, it is enough to release pedal 1 very slightly so that all the exhausts are “armed” or “re-armed”. By releasing pedal 1 further to the harmonic position, we can easily return to the situation in Figure 4.
  • the mechanism applied to the upright piano does not differ fundamentally from mechanism explained above.
  • elements similar to those of figures 2 to 6 are indicated by identical reference numbers followed by the sign "premium”.
  • the mechanism according to the invention applied to an upright piano differs essentially of that of the prior art, as represented in the figure 1, by the fact that the spoon 103 does not act directly on the damper support 104 ', but via a 13 'exhaust on which is also likely to act the harmonic bar 111 '.
  • the spoon 103 which is for example made of a resilient metal, is associated with a spoon holder 43, connected to the button (not shown) and likely to rotate in the opposite direction to said key.
  • the spoon 103 is in contact with a heel in bracket 14 ', in one piece with the exhaust 13' and in which is provided with a housing intended to receive a end of a helical spring 42, the other end of which is fixed to the damper support 104 '.
  • the damper support 104 ′ is capable of pivoting around an axis 48 mounted on a horizontal element 45, which element 45 is itself mounted on the vertical part 31 of the piano. At rest, the damper support 104 'is held against the rope 107' by a compressor spring 44, which is integral with the element 45. As is the case with all upright pianos, the damper 106 'and the cord 107' are also vertical.
  • harmonic bar 111 ' In addition to the harmonic bar 111 ', there is a strong bar 112', which bars depend on sets of corresponding supports 22 'and 23', respectively, pivotally mounted about an axis 12 '. At rest, the harmonic bar 111 'is in contact with the spout 15' of the exhaust 13 '.
  • FIG. 8 represents the detail of a linkage mechanism according to the present invention, constituted by a control rod 4 ′, one end of which supports a horn 5 ′ of a shape substantially different from that of the horn 5 of FIGS. 2 to 6, said 5 'horn having a roughly trapezoidal base structure in the small base of which is formed an indentation 52 of irregular shape, of which a "corner" part is adapted to offer a housing at the spherical end of the control rod 4' .
  • the horn 5 ' is rotatably mounted around an axis 7', transverse to a vertex 5'b of the trapezoid, on a clevis 8 'which is, in this case, fixed to the above-mentioned vertical part 31 of the upright piano structure .
  • a connecting rod 19 ' is anchored, pivoting, on the one hand, around an axis 16' mounted on the horn 5 'at its angle 5'c and, on the other hand, around an axis 40' mounted on a drive plate 47 'of harmonic bar 111'.
  • a connecting rod 20 ' is anchored, pivoting, on the one hand, around an axis 17' mounted on the horn 5 'at its angle 5'a and, on the other hand, around an axis 41 'mounted on a drive plate 48' of 112 ' strong bar.
  • the operation of the assembly is substantially identical to that of the mechanism described with reference to FIGS. 2 to 6.
  • the respective cooperation of the strong bar 112 'with the battery of damper supports, such as 104', and of the harmonic bar 111 'with the battery of nozzles, such as 15', of exhausts, such as 13 ', is identical.
  • certain differences result from the fact that the cord 107 ′, the damper 106 ′ and its support 104 ′ are vertical and no longer horizontal.
  • the distal end of the key 101 is likely (up to the harmonic position) to come directly into contact with the heel 14 of the escapement 13, as is described above, and to lift said exhaust, when the button 101 is pressed, which results in an upward pivoting of the damper support 104 on which said exhaust 13 is pivotally mounted, and therefore in the separation of the damper 106 with rope 107, on which it normally rests.
  • the exhaust 13 which is free from any constraint, returns to its rest position under the effect of gravity.
  • the invention makes it possible to carry out a series of back-and-forth operations between the harmonic function and the strong function , with intermediate sequences of muted notes (keys released without simultaneous depression of the pedal or in the harmonic position) and a certain number of notes which remain ultimately not muffled (keys released beyond the harmonic position), provided that the pedal has never been fully released.
  • transition from the strong function to the harmonic function, and vice versa is precisely regulated by construction and will depend on the dimensions and the relative positions of the various elements previously described.
  • the transition between these two functions can be made more easily perceptible for the pianist by adding to the mechanism a mechanical part capable of moving and encountering, on passing the harmonic position, an obstacle generating, for the pianist, a feeling of hard point to cross in the pedal stroke.
