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 rods 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 rods or levers, assembly rivets and chains to the different forks.
  • the rod operates alternately in compression and in traction, as do the control levers or 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.
  • Patent DE-C-444 941 (L. Musolff) describes a mechanism for controlling the tension of the strings of a harp by means of pedals and cables linked to the strings. According to this document, the modification of the sound emitted by the plucked strings is obtained by varying the tension of the strings. This operating principle is relatively original, but clearly has the drawback of requiring a complex adjustment mechanism for each string. The invention discussed is clearly different from the Musolff harp, since we preferred the use of string plucking forks which make it possible to vary the length of vibration, and not the tension of the strings.
  • Patent DE-C-352 623 (OTTO) relates to a clamping mechanism for each string of a harp by means of a set of two superimposed forks whose rotation is caused, successively and differentiated, by a pulling cable 1.
  • the connection between the traction cable to each of the two forks is constituted by two linkages each comprising a succession of cams rocking on axes and connected by links and levers, assembly rivets and chains.
  • the transmission system thus described has many drawbacks, essentially linked to the large number of parts which it is necessary to use, and to the significant wear which occurs during use and which quickly harms the proper functioning of the together, producing in particular rapiderr ⁇ Mit unwanted extraneous noise.
  • 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 device double action transmission consisting of a first traction cable which is connected on one side to a series of first upper forks making a pluck of the associated strings to obtain the sound of the barrel, and on the other side to an organ of tilting control, of a second traction cable which is connected on one side to a series of second lower forks real sing a pinching of the associated strings to obtain the sharp sound, and on the other side to a pedal, said second cable actuating said tilting control member so as to translate the traction exerted on said cable in two successive angular movements of the forks higher, then lower.
  • the tilting control members consist of a rotary cam disc, having a circular hub for returning the second traction cable, and a pivoting part connected to said first traction cable and resting on said cam disc.
  • the cables are held in tension by means of return springs mounted between the abutment of the harp and one of the ends of each of said cables respectively.
  • 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 course deviation, the length of which is greater than the length of peripheral displacement of the circular hub corresponding to the displacement stroke of the first traction cable (via the cam and the tilting member), the traction force of the return springs of the tensioner being less than the traction force of the return spring connecting said second traction cable to the abutment of the harp.
  • 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 your rivets are eliminated and that a single cam is now used with a swivel bar, which considerably reduces the problems of assembly, adjustment and of course 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 crankset 16 pivoting about an axis 17 secured to the base 5.
  • This crankset is connected to the pedal 9 and is pushed back to 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 pivoting 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 at one of its ends by a return spring 31 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 attached to the tension springs 38 lowering the axis 20 in the lateral 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 26 and 33 of the forks 7 and 8 are offset by the same angle - about 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.
  • the cam 28 rotates in the same direction and on the same angle the bar 10 which pulls on the cable 11 thereby bringing the arms 25 into the position shown in FIG. 4 by stretching the return spring 24, the forks 7 then plucking the strings 1;
  • the cable 14 is pulled while being brought into a rectilinear position because the springs 38 pulling down the tensioning axis 20 are designed looser than the return spring 31 and fail before the latter. link results that the arms 32 of the lower forks 8 do not pivot.
  • Fig. 6 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, of which a branch 45 (corresponding to the horizontal bar of T) is shaped in the same way as bar 10, while its branch 46 (corresponding to the vertical bar of T) is flexible and ends with a curved end 47.
  • the outer face of this end is provided with a groove 48 in which the cable 14 circulates.
  • 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 T 44, so that at rest this cable 14 forms the desired course deviation 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 maintaining the latter in the rest position, 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 tension of the spring 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.
