Definitions

  • the present invention relates to a harp of the type comprising a set of strings stretched between an arm called a console and a resonator forming a soundboard, connected at the level of the abutment of the harp, and whose vibrating length is adjustable by means of pairs of forks able to pluck the strings and actuated by a mechanism, in particular with double movement, housed in a console and connected to pedals placed in the base of the harp.
  • the pedal harp plucked string instrument
  • the pedal harp holds a special place, especially in chamber music.
  • it consists of a set of 38 to 48 strings, of unequal lengths, stretched between a console and a table secured to a box, at 45 ° from the plane of the strings. They include a vertical column connected to a pedestal including a pedals and of which the console and the table are joined together at the level of the abutment of the harp.
  • the known triangular harps comprise one or two rows of forks with two teeth offset along each string and intended, thanks to their action of pinching the string between them, to respectively shorten the strings by 1/18 of the length of string remaining in vibration, so as to be able to provide the sound and the sharp sound from the basic sound, the flat.
  • each pedal actuates the forks associated with the different strings by means of a transmission mechanism currently consisting of a vertical rod housed in the column and connected, on the one hand, to the pedals and on the other hand, at its upper part, to a set of cams tilting on axes and connected by links or levers, assembly rivets and chains to the different forks.
  • a transmission mechanism currently consisting of a vertical rod housed in the column and connected, on the one hand, to the pedals and on the other hand, at its upper part, to a set of cams tilting on axes and connected by links or levers, assembly rivets and chains to the different forks.
  • the rod operates alternately in compression and in traction, as well as the levers or control rods located in the console, which has the effect that, on the one hand, there is a buckling of the vertical rods and the control levers by compression with harmful appearances of vibration, and on the other hand, when the holes of the assembly rivets are worn, the rivets move in their housings with each movement emitting a notable noise click-clack making mandatory what is called a long, expensive and random re-grouping.
  • cams and levers are almost completely different delicate pieces of invoice, requiring precise manual adjustment and therefore a high cost price.
  • an object of the present invention is to solve the drawbacks mentioned above by reducing the number of parts used, the cost price of the instrument, while offering appreciable flexibility of use for the user, in particular by following the removal of unwanted noise.
  • the mechanism for actuating the forks consists, for each of the seven degrees of the range, of a double action transmission device constituted by a swivel bar, the upper end of which is connected by a first flexible traction cable to the first upper forks, making a plucking of the associated strings to obtain the natural sound and which rests with possibility sliding on a cam disc, on the circular hub of which flows without sliding a second flexible traction cable connected to second lower forks, pinching the associated strings to obtain its sharp, and to the associated control pedal .
  • the cables are kept in constant tension by means of respective return springs connected to the ends of the cables and fixed to the abutment of the harp.
  • this transmission system only works permanently in traction, without alternating effects of compression and traction and therefore silently.
  • the transmission device includes a compensation tensioner requiring the second traction cable to form at rest a loop, the length of which corresponds to the peripheral length of the circular mcysu carrying the cam, the latter of which turns to tension the cable in a rectilinear position between its supports.
  • the supports of the upper forks and the supports of the lower forks are firmly connected respectively to the first cable and to the second cable by arms offset by the same angle on the same side of the plucked strings.
  • the cam has the shape of an appendage with parallel lateral sides tangent to the circular hub and whose outer peripheral edge is circular so that, when the mechanism is at rest, which corresponds to the basic sound for each said forks do not pinch the associated cords, and that, when the second traction cable is actuated using the pedal, it stretches in the rectilinear position, the tensioner being pushed aside or pushed back simultaneously without the supports of the lower forks moving, causing the cam to rotate about a quarter of a turn which pushes back the bar and pulls the first pulling cable which makes the arms of the supports of the upper forks rotate by about a quarter of a turn, which therefore pinches the strings at the upper level by shortening them by 1/18 of the length remaining
  • this system provides for each actuation mechanism on a very limited number of parts working in traction, which is far less than the number of parts used in harps known to date. It will be noted that all the levers or rods, the rods, their end caps and the rivets are eliminated and that a single cam is now used with a pivoting bar, which considerably reduces the problems of assembly, adjustment and naturally the price of come back.
  • FIG. 1 representing an overall view of the harp according to the invention, the reference 1 designates the set of strings stretched between an upper console 2 and a soundboard 3 secured to a body 4.
  • the console 2 is connected, by the vertical column 6, to the base 5 of the harp to which the table 3 and the body 4 are also integral.
  • only one of the actuation mechanisms of sets of upper forks is shown.
  • the harp has a total of seven associated pedals at the seven degrees or notes of the scale and which can take a high position, corresponding to the flat sound and two lower positions (not shown) corresponding to the white sound and the sharp sound.
  • the mechanism consists essentially of a double action transmission device constituted by a bar 10 pivotally mounted in the column 6 and the upper end of which is connected by a first flexible traction cable 11 to the upper forks 7 and which rests with possibility sliding on a cam disc 12, on the circular hub 13 which circulates without sliding (or is secured in any other appropriate manner) a second flexible traction cable 14 connected to the lower forks 8 and which is connected by a yoke 15 to a 16 pivoting crankset around an axis 17 secured to the base 5.
  • This pedal is connected to the pedal 9 and is pushed back into the high position - at rest - by a coil spring symbolized at 18.
  • the reference 19 designates axes on which the forks 7 and 8 are mounted, and the reference 20 designates a compensation tensioning axis, the role of which will be defined with reference to FIGS. 2 to 5.
  • the swivel bar 10 is rotatably mounted on a support bracket 21 secured to the upper part of the column 6.
  • the cable 11 is connected to the upper end of the bar 10, in a lumen 22 thereof, by means of a suitable fixing member 23 such as a rivet or a weld. Otherwise, the cable can simply be tied to the bar 10.
  • the cable 11 is connected to the abutment (not shown) of the harp by a return spring 24.
  • the cable 11 passes through a bore formed in an integral arm 25 axis 19 carrying a support 26 of a fork 7 whose teeth enclose the associated cord 1.
  • the cable 11 is locked in position in the arm 25 by a clamping screw 27.
  • the bar 10 rests with the possibility of sliding on the cam 28 of a cam disc 29, the circular hub 30 of which has a groove (not visible) in which flows without the possibility of sliding, by being fixed there for example. by a clamp symbolized at 30a, the traction cable 14 connected to one of its ends by a return spring 3 1 to the abutment of the harp.
  • the cable 14 passes through a bore formed in an arm 32 integral with the axis 19 carrying a support 33 of a fork 8, the teeth of which enclose the associated cord 1.
  • the cable 14 passes over a guide roller 34, the axis 35 of which is integral with the console 2, and around the tensioning axis 20 formed by a cylindrical element provided with a groove 36 and at the ends 37 of which are tension springs 38 lowering the axis 20 in the side openings 39 formed in parts of the console 2.
  • the cable 14 is locked in the arm 32 by a tightening screw 40.
  • the bar 10 As shown in Figure 2 and as best seen in Figure 3, the bar 10, the arms 25 as well as the arms 32 of the supports 2,6 and 33 of the forks 7 and 8 are offset by the same angle - approximately 45 ° - to the right with respect to the respective cords 1 when the entire mechanism is at rest.
  • the tensioning axis 20 is in the low position under the action of the springs 38.
  • the cam 28, which has - as shown - the shape of a projecting appendage with lateral sides 41, 42 parallel rectilinear and whose edge outer device 43 is circular.
  • FIG. 3 corresponds to the case where the associated pedal 9 is in the high position, that is to say that the mechanism is at rest.
  • the sound provided for strings 1 is a flat.
  • Fig.6 there is shown an alternative embodiment of the mechanism of Fig.2, and according to which the bar 10 is replaced by a bent lever in T 44, including a branch 45 (corresponding to the horizontal bar of T) is shaped in the same way that the bar 10, while its branch 46 (corresponding to the vertical bar of the T), is flexible and ends in a curved end 47. The outer face of this end is provided with a groove 48 in which the cable 14 flows.
  • a bent lever in T 44 including a branch 45 (corresponding to the horizontal bar of T) is shaped in the same way that the bar 10, while its branch 46 (corresponding to the vertical bar of the T), is flexible and ends in a curved end 47.
  • the outer face of this end is provided with a groove 48 in which the cable 14 flows.
  • the branch 46 plays the role of the compensating tensioner (20, in FIG. 2), while the tension springs 38 are eliminated, as is - possibly - the guide roller 34.
  • the tension springs 24 and 31 are appropriately dimensioned by exerting on their respective cables a tension greater than that produced by the flexible branch 46 of the T44, so that at rest this cable 14 forms the desired loop by exerting on the end 47 of the branch 46 of the lever 44 only a reaction force less than the force exerted by the cable 11 on the lever 44 and keeping the latter in position rest, and so that, when the pedal is in the intermediate position, said end 47 exerts pressure on the cable 14 (which will drive the cam disc 29 when the corresponding pedal is released) but which is less than the spring tension 31 on this cable 14.
  • the present invention provides a mechanism for adjusting the vibrating length of the strings of a harp, simpler than existing systems, requiring fewer adjustments and comprising significantly fewer parts than known devices, which gives it a more attractive cost price.
