The 3rd pedal 6c is so-called sympathetic response pedal (or strong pedal).Its actuating causes all dampers 8 of piano to be raised leaving string.Damper 8 only is moved back on the string when the sympathetic response pedal discharges.
The 4th pedal 6d is so-called harmony pedal, this harmony pedal is suitable in the remanent magnetism position all dampers 8 being raised and leaves string 3, and the damper 8 that only allows to link with key 5 (key 5 is depressed when the harmony pedal is maintained at the remanent magnetism position) turns back on separately the string.The harmony pedal also can be provided with resonant function when further being operated, take this all dampers 8 and be raised and leave string, and no matter whether key 5 is depressed when pedal is in the remanent magnetism position.
As shown in Figure 2, parts 7 comprise harmony bar 9, and this harmony bar limits an internal cavity, and sympathetic response bar 10 (invisible in Fig. 2, referring to Fig. 3) extends in the inside of internal cavity.
Each pedal 6a, 6b, 6c, 6d and separately order bar 11a, 11b, 11c, 11d link, and the order bar is the part of foot's order actuating system.Sympathetic response pedal 6c is connected to sympathetic response bar 12c by order bar 11c, and sympathetic response bar 12c is installed on the support member 13c pivotally, and support member is fixed on the piano body (not shown).
Similarly, harmony pedal 6d is connected to harmony bar 12d by order bar 11d, and the harmony bar comprises outside plate 62, and outside plate is installed on the support member 13d that is fixed to the piano body pivotally.Sympathetic response bar 12c and outside plate 62 extend parallel to each other.
One U-shaped support 61 is connected from outside plate 62 extension downwards and with outer slab integral, and be formed for the bearing of harmony spring 16d, the other end is put and is leaned against on the inner panel 63, and inner panel rotates with respect to outside plate 62 to center on the axis identical with respect to the rotation of support member 13d rotation with outside plate 62 by Bearing Installation.
And transverse bar 14 is pivotally connected to the support member 13e that is fixed to the piano body and goes up and extension above sympathetic response bar 12c and harmony bar 12d outside plate.Transverse bar 14 carrying sympathetic response bar 15c, the sympathetic response bar extends at the inner the second end that extends and be connected to sympathetic response bar 10 of cavity from the first end that is connected to transverse bar 14.Therefore, sympathetic response bar 15c passes the hole 73 in the harmony bar 9.
Transverse bar 14 also carries sympathetic response spring 16c, and this sympathetic response spring is suitable for cooperating with the interfacing part 17 of facing of piano body.
The inner panel 63 carrying harmony bar 15d of harmony bar 12d, the harmony bar has the first end that is connected to inner panel 63 and is connected to the second end of harmony bar 9.
As being shown specifically among Fig. 4, support member 18 is fixed on the piano body.Sympathetic response support 19 has by bearing, is installed in first end on the support member 18 pivotally around rotation X.The second end of sympathetic response support 19 is fixed or otherwise is connected to sympathetic response bar 10.In this example, the sympathetic response bar is illustrated and comprises the profile sheeting plate, this profile sheeting plate have hollow rectangular cross section for example by the metal main body 65 of light weight, this light weight metal supports to be turned round and bending resistance, for example AU4G type constructed of aluminium.In this example, three hollow spaces are along profile: two T types with respect to center+type part partly extend.These hollow spaces allow to alleviate the weight of sympathetic response bar, and guarantee its favorable mechanical performance.Thicker part is for cutting thread and/or hold screw and/or other setting tool is favourable.The actuation part 66 that the carrying of the top surface of main body 65 is for example become by the felt of the xsect of planar rectangular is so that cooperate with damper arm element.
As shown in Figure 4, harmony bar 9 is made by the profile sheeting plate, and this sheet material plate for example by the light weight metal of antitorque and bending resistance, is made such as AU4G type aluminium.Easily, harmony and sympathetic response bar are manufactured from the same material.First wing 20 and second wing 21 that harmony bar 9 is manufactured to be had U type profile substantially, this profile to have toward each other and be connected with each other by substrate 22.First wing 20, substrate 22 and second wing 21 limit internal cavity 23 together, and sympathetic response bar 10 extends in the rest position of system in cavity inside.First wing 20 of harmony bar 9 is fixed on the mounting bracket 24, and this mounting bracket is pivotally connected on the support member 18 around rotation X, and is independent of sympathetic response support 19.First wing 20 penetrates a plurality of mounting holes, and each mounting hole is used to hold the support 26 (not shown, referring to Fig. 3) that is used for corresponding damper arm element.This support 26 extends to the second end of the receiver hole 27 of the damper arm element that is defined for separately from the first end that is fixed to harmony bar 9 at mounting hole 25.
As above described referring to Fig. 2, the basal surface of the substrate 22 of harmony bar 9 limits the actuation part by the reception actuating of harmony bar 15d from harmony pedal 6d.Substrate 22 also is provided with the hole, and harmony bar 15c extends through this hole (referring to Fig. 3), and harmony bar 15c cooperates with the actuation surfaces 28 of sympathetic response bar 10.
As shown in Figure 3, damper support component 30 comprises damper arm element 31 and centers on the escapement nose 32 that pivot axis 33 is pivotally connected to arm 31.Arm 31 is installed on the support 26 pivotally around pivot axis 34, and this pivot axis 34 extends along direction X in the present embodiment, and with coaxial with respect to the rotation of the harmony bar of support member 18 and sympathetic response bar.Damper bar 35 has the opposite second end that for example is pivotally connected to the first end of arm 31 and is connected to the damper 8 that links at pivot axis 36 places.
The basal surface of damper arm element 31 comprises the actuation part 42 such as the basal surface of guide 48, and this actuation part is in the face of sympathetic response bar 10.Physical location with respect to the actuation part 42 of harmony bar can accurately be regulated, as following 8 described with reference to the accompanying drawings.
Operation referring now to the 5a-5g descriptive system.
Fig. 5 a systematically illustrates corresponding to the system in the rest position of above-mentioned accompanying drawing 3.
Shown in Fig. 5 b, when not having pedal to be operated, the actuating of key 5 will make its actuation part 38 contact with the correspondent button actuation part 37 of escapement nose 32, thereby cause escapement nose 32 with respect to the rotation of arm 31 around pivot axis 33, the corresponding butted part 41 of butted part 40 contact arms 31 on the escapement nose.Then, escapement nose 32 is prevented from respect to being further rotated of arm 31, thereby the further motion of key 5 causes the entire portion of arm 31 and escapement nose 32 with respect to the rotation of harmony bar 9 around rotation 34, as shown in Fig. 5 b.This rotation will cause moving upward of damper bar 35, therefore damper will be raised and leave corresponding string.
When release key 5, system will be moved back into the position shown in Fig. 5 a.
When harmony pedal 6d is depressed to its remanent magnetism position, this will cause the rotation of whole harmony bar 12d (Fig. 2) around support member 13d, and this will cause moving upward of harmony bar 15d.Rotatablely moving of harmony bar 12d also will cause the rotation of transverse bar 14 around its support member 13e, while compression spring 16c, and therefore also cause moving upward of harmony bar 15c.Shown in Fig. 5 c, in this position, harmony bar 9 (and sympathetic response bar) is around the pivot axis X rotation several years, and lip limit 29 upwards promotes escapement nose 32, and do not cause that escapement nose 32 is with respect to the rotation of arm 31 around pivot axis 33.Therefore, this of escapement nose 32 moves upward and causes arm 31 to rotate up its remanent magnetism position around pivot axis 34.Therefore, this will cause moving upward of damper bar 35.Therefore, all dampers are raised and leave string.
When harmony pedal 6d remains on this remanent magnetism position, if given key 5 is pressed by the pianist, its actuation part 38 will be cooperated with the key actuation part 37 of separately escapement nose 32, thereby cause escapement nose 32 with respect to the rotation of arm 31 around pivot axis 33, and the afterbody 39 of escapement nose 32 is thrown off the joint on the lip limit 29 of harmony bar 9, shown in Fig. 5 d.
When this key 5 is released, when harmony pedal 6d still remains on this remanent magnetism position, damper arm element 31 will be rotated down its rest position around pivot axis 34 with respect to support 26, take this that damper bar 35 moves downward and damper is moved back into corresponding string, shown in Fig. 5 e.This only is pressed and discharges at key 5, and takes place when the harmony pedal remains on the remanent magnetism position.
Therefore, in this stage, when the harmony pedal still remains on identical remanent magnetism position, some arm elements in the damper arm element 31 have the structure of Fig. 5 c, and other arm elements in the damper arm element 31 have the structure of Fig. 5 e, and no matter whether the correspondent button of keyboard is pressed simultaneously and discharged.
In this stage, the 6d if the pianist releases the pedal, all damper arm elements will be moved back into their rest position.
On the contrary, if the concert performer further steps on harmony pedal 6d, the outside plate 62 of harmony bar 12d be further rotated the further motion that will cause transverse bar 14, inner panel 63 is held in place simultaneously, thereby depresses harmony spring 16d.Moving upward of transverse bar 14 will cause further moving upward of sympathetic response bar 15c.Shown in Fig. 5 f, this will cause sympathetic response bar 10 being further rotated around rotation X, take this corresponding actuation part 42 of the actuation part 43 of sympathetic response bar 10, and will cause being in damper arm element 30 in the position of Fig. 5 e around the rotation of pivot axis 34 with engaging arms 31.This rotation relates to the upward displacement of the damper bar 35 that links, and the damper of taking this to link is raised and leaves corresponding string.
If discharge harmony pedal 6d in this stage, then aforementioned stages will be got back to by this system.
If the concert performer continues to activate harmony pedal 6d, arm 31 will make the afterbody 39 of escapement nose throw off the joint on the lip limit 29 of harmony bar 9 with respect to pivot axis 34 to being further rotated of its remanent magnetism position, take this also will allow escapement nose 32 with respect to the rotation of arm 31 around pivot axis 33.Simultaneously, this further motion also will make the damper support component 31 corresponding to the key that is not pressed in the remanent magnetism position of harmony pedal and discharges be in the remanent magnetism position shown in Fig. 5 g.Otherwise all damper arm elements 31 and escapement nose 32 have the structure of Fig. 5 g in this stage, take this all dampers and are raised and leave string.In this structure, the key actuation part 37 of escapement nose 32 is very away from the corresponding actuation part 38 of correspondent button 5, and taking this key 5 can be pressed, and can not cause escapement nose 32 with respect to the rotation of body 31 around pivot axis 33 that link.
Therefore, arm 31 has along one degree of freedom from its rest position to its remanent magnetism position and further moving to its sympathetic response position.
When harmony pedal 6d was released from this structure, the structure shown in Fig. 5 c was got back to by system, got back to the structure shown in Fig. 5 a then.
When sympathetic response pedal 11c is stepped on by the concert performer, it will cause the rotation of sympathetic response bar 12c with respect to support member 13c.Sympathetic response bar 12c is engage lateral bar 14, thereby causes the rotation of transverse bar 14 with respect to support member 13e, and the moving upward of sympathetic response bar 15c, and takes this sympathetic response bar 10 separately around longitudinal axis X rotation, takes this damper arm element 31 and occupies their remanent magnetism position.
Fig. 6 is the detailed view that connects between harmony bar 9 and the harmony bar 12d.As shown in Figure 6, harmony bar 15d comprises the second end that is provided with ball 44, rotation in the recess 45 of ball on being fixed on harmony bar 9.
On relative first end, the harmony bar is included in the ball 44 that rotates in the recess 45 of sleeve 46.Joint 64, for example self-lubricated joint is integrally formed between ball and the recess.This joint can be made such as nylon by plastic material.This can form the quiet and/or lasting operation of foot's order.Sleeve 46 has external thread (cannot see) under this angle of detailed view, threaded ring 47 is cooperated with this external thread.Ring 47 is around sleeve 46 rotation, thereby moves upward, up to it by sleeve 46 being fixed on the harmony bar 12d with the cooperating of lower surface of bar.
Top assembly makes can both regulate harmony bar 9 easily to any piano.In fact threaded ring 47 and harmony bar can place the outside (not shown) of piano body, thereby allow to regulate easily.Bar extends through hole suitable in the piano body (71,72, referring to Fig. 1).
Be used for the harmony bar though this assembly is described, should also be mentioned that the sympathetic response bar that is used to piano, or any other similar bar can have above-mentioned geometry (Fig. 6).
And, as shown in Figure 7,, extension bar 67 is fixed to sympathetic response bar 10 according to another aspect.The different embodiment of the part with two skies that should be noted in the discussion above that the sympathetic response bar are also shown in Figure 7.Extension bar 67 is extended and has the band soft material along the length of parts 7,, and be arranged to limit the stroke of damper arm element such as the lower surface of felt.When sympathetic response bar 10 does not activated, the low position that extension bar is in, thus stop the long stroke of damper.When bar adjustable ground that extension bar is rung together is integral, allow the longer stroke of damper, no matter whether the sympathetic response bar activated.Thereby allow the position of Fig. 5 g.
Find out obviously that from top description above-mentioned parts can be made easily, so that be installed on any suitable piano.Consider the position and the interval of width and the string and the key of piano, enough make the appropriate length of (by punching press or extruding) belt profile sheet material plate, so that form harmony bar and/or sympathetic response bar, and at correct position mounting hole 25, so that containment bracket 26 and the damper arm element 31 that links.Therefore, all elements of parts 7 can be by standardization.No matter whether above-mentioned parts comprise foot's order or conveyer, all can be on being fixed to piano after, at the scene, on piano by accurately tuning.
For example, in the piano field, be well known that and use so-called " guide ", represent such as reference number among Fig. 3 48.This guide is accurate regulating device, and this device allows easily to regulate the geometric relative position of mechanical part.For example, guide is set at below the damper arm element, so that cooperate with the sympathetic response bar 10 on the escapement nose of the mallet (not shown) of key end place, bump string.
According to another aspect of the present invention, this guide comprises bar, and the first end car of bar has screw thread (end is interior by the arm 31 that screw thread inserts among Fig. 3), and the second end of bar is fixed in the head 49, in described embodiment, this head has the adjusting part of being made by the cylinder shape belt gear.The corresponding tool 50 of position that is used for accurately regulating guide 48 is shown in Fig. 8 a and the 8b.Shown in Fig. 8 a, this instrument comprises the handle 51 with housing 57 one, and holds the swingle 52 that extends along the rotation of setting 60 in inside.An end of bar 52 is connected to actuation button 53, the other end comprise be supported in the bearing 55, with the annular screw 54 of handle 51 one.Guide 48 is mounted to respect to housing 57, pivots around regulating pivot axis 58, and this regulates the rotation quadrature of pivot axis and annular screw 54.In use, the band toothed portion 49 of guide inserts in the guide reception space 59 of instrument.Button 53 causes the rotation of annular screw 54 by the user around the rotation of rotation 60, takes this that guide is rotated and screw in or screw out its receiving element along adjustment axis 58.The easy setting of guide may be because not parallel, and such as the setting and the adjustment axis of quadrature, this allows to come by the finite motion of instrument the position of guide, and does not interfere with the adjacent component of piano.
Above-mentioned and instrument that link can be used for still also can be used in any other suitable piano in the piano as described above with reference to figure 1-7.
