Abstract

The utility model provides a vertical piano synthetic playing accelerator, which is mainly composed of a synthetic playing acceleration spring, a guiding groove for the synthetic playing acceleration spring, and an auxiliary pushing spring. The utility model has the advantages that the structure is reasonable and simple, and the utility model can effectively enhance the function of synthetically playing with high speed.

Description

Upright piano repetition accelerator

The utility model belongs to musical instrument and makes the field.

The domestic and international at present upright piano of producing, because of the limitation of hammered string instrument structure, the repetition function owes perfect.When the player plays the melody of quick beat, or when continuing playing a certain phoneme fast, can not get back to fast to change because of the hammered string instrument push rod and hit the device original position, cause tup to hit that string is unable maybe can not to hit the string pronunciation.Have the higher finger that lifts of player only and leave the key face, push rod just can set back, and makes the next one play pronunciation.And when continuing playing fast, player's height finger of raising one's hand is again extremely inconvenient.

The utility model provides a kind of repetition accelerator.The utility model is finished as follows:

Under the situation that does not change former hammered string instrument structure, rest the head on the upper end lengthening and be provided with repetition acceleration spring gathering sill at protocercal tail, extend and device repetition acceleration spring in former holder shelves upper end, between push rod and adjusting knob balk, increased the auxiliary spring that pushes away in addition.After utilizing tup to hit string, the tail pillow returns the inertial force by the holder shelves, make repetition spring pressurized and energy accumulation (elastic force), one be lifted away from the key face slightly when the player points, gangbar falls, the moment that the holder shelves separate with the tail pillow, the repetition spring discharges elastic force, pushes tup to the place ahead, this travel forward to reset to push rod reserved the space, push rod is got back to fast to change and is hit the device original position push rod spring and auxiliary pushing away under the thrust of spring.Under this state, player's finger (not needing finger is pushed into former height) of raising one's hand on again can repetition this key pronunciation, repetition dependable performance fast.

The utility model is described in further detail below with reference to accompanying drawing.

Fig. 2 upright piano repetition accelerator elastic force is accumulated synoptic diagram

Fig. 3 upright piano repetition accelerator work synoptic diagram

Mainly contain keyboard (1) with reference to Fig. 1 upright piano repetition accelerator, gangbar (5), push rod (7), push rod spring (6), the auxiliary spring (10) that pushes away, auxiliary pushing away on the balk (9) that spring (10) is placed in adjusting knob (8), adjusting knob (8), the repetition acceleration spring gathering sill (16) that tail pillow (11) and tail pillow (11) upper end are provided with, the repetition spring assembly groove (13) that holder shelves (12) and holder shelves (12) upper end are provided with is equipped with repetition acceleration spring (14) in the groove (13), a termination of spring (14) is in spring assembly groove (13), another termination is in spring gathering sill (16), and is and fixing with fixed pin (15).Commentaries on classics is hit device (17) and is combined as a whole with tup (19), and tup (19) rear end is dropped on by on the shelves (18).Tup (19) the place ahead is piano string (21).(22) (24) are pedestal, are installed on the girder (23).Pedestal (25) is installed on the gangbar (5).

The player plays lower keyboard (1), and its direction of motion (2) transfers direction of motion (4) to because of fulcrum Xiao Zi (3) factor, drives gangbar (5), push rod (7) rising; Push rod (7) promotes to change and hits the tup (19) that device (17) [rotating according to pedestal (22)] combines as a whole with it, by shown in the direction of motion (20), advance to piano string (21), during apart from string (21) 5 millimeter, push rod (7) is conditioned button (8) and trips, and compression push rod spring (6) and the auxiliary spring (10) that pushes away, for resetting, the push rod (7) of next stage accumulates elastic force [key this moment (1) sinks 8 millimeters], push rod (7) top is left to change and is hit device (17) lower end, tup (19) is advanced string (21) by before the inertia, and above-mentioned action keyboard (1) always sinks 10 millimeters.

After tup (19) hits string (21), according to inertia to by shelves (a 18) direction return, with reference to Fig. 2, return tail pillow (11) and (12) intersection mutually of holder shelves in the way, in the intersection, an end pressurized of tail pillow (11) upper end gathering sill (16) interior repetition acceleration springs (14), and energy accumulation (elastic force).

With reference to Fig. 3, when player finger is lifted away from 2 to 3 millimeters in key (1) face, key (1) face rises, driving gangbar-(5) falls, at this moment holder retaining (12) separates with tail pillow (11), in the moment of Separation, repetition acceleration spring (14) release energy (elastic force), promote about 4 to 5 millimeters of tup (19) (26) motion forwards, this motion has been reserved push rod (7) top and commentaries on classics and has been hit space between device (17) lower end for push rod (7) resets, push rod (7) top is got back to fast to change and is hit device (17) lower end original position, for hit string (21) action next time, carries out auxiliary the preparation.

When player finger was lifted away from 6 to 7 millimeters in key (1) face, this phoneme of legato that just can be reliably strong made player's the more perfect performance of both hands skill.And do not have a hammered string instrument of this device, when push rod (7) is lifted away from 7 to 8 millimeters in key (1) face at player's finger, just can gets back to change and hit device (17) original position.Make troubles for legato fast.

Claims

1, a kind of have a keyboard (1), Xiao Zi (3), gangbar (5), push rod (7), push rod spring (6), the auxiliary spring (10) that pushes away, adjusting knob (8), adjusting knob balk (9), tail pillow (11), holder shelves (12), change and hit device (17), by shelves (18), tup (19), pedestal (22), (24), (25), the upright piano repetition accelerator of girder (23), it is characterized in that: there is spring gathering sill (16) tail pillow (11) upper end, there is spring resettlement groove (13) holder shelves (12) upper end, the multiple wife's acceleration spring (14) of device in the groove (13), spring (14) is fixing by fixed pin (15).
