Weight block ribs 13W and 13B are provided with respectively correspondingly in pairs with white key 20 and black key 40 respectively.All wt piece ribs 13W is arranged on along the identical position of fore-and-aft direction, and all wt piece ribs 13B also is arranged on along the identical position of fore-and-aft direction.After weight block ribs 13B is arranged to proportion gauge block ribs 13W position and more leans on, and along fore-and-aft direction very little lap is only arranged between weight block ribs 13W and the weight block ribs 13B.
Above-mentioned pivot 14W and above-mentioned pivot 14B extend through every couple of weight block ribs 13W and every couple of weight block ribs 13B respectively.After pivot 14B is arranged to more lean on than pivot 14W position, and these two pivots are not overlapping along fore-and-aft direction.
Inclined surface 19 is formed at the front portion of keyframe 10.As hereinafter described, when being connected to weight block 50 on the keyframe 10 and when being connected to key unit KU on it, inclined surface 19 is carried out guiding function is installed.In addition, as Fig. 1, Fig. 4 B, Fig. 6 and shown in Figure 7, the parallel a plurality of ribs 11 of along continuous straight runs are formed at the most forward part place of keyframe 10 with white key 20 corresponding positions.Above-mentioned key guide portion 12 of vertically extending is integrally formed, so that key guide portion 12 is connected on the front surface of rib 11.
As shown in Figure 1, the rear aperture of the bearing 51 of weight block 50.By this open side from this bearing 51 bearing 51 is installed on this pivot 14, as shown in Figure 6, a plurality of weight block 50W and 50B are respectively around pivot 14W and pivot 14B pivoting action.When weight block 50 be in weight block 50 can free state (state of key is not set) in pivot 14 head lamp brush guard pivots motions in the time, rearward end 52 is the spacing detent 84 in butt bottom (referring to Fig. 1) owing to the gravity of himself, and rearward end 52 is positioned at the below so that leading section is positioned at the top.
Tongue piece 56 (56W, 56B) is provided with in the mode that the downside from the bearing 51 of weight block 50 extends backwards.Tongue piece 56 is made by barras etc. and is had a flexibility.When bearing 51 was installed on pivot 14, tongue piece 56 was carried out guiding function.In the peristome of bearing 51, near the zone the pedestal of tongue piece 56 is narrower than near the most advanced and sophisticated zone of tongue piece 56, therefore makes the pivot 14 that is installed in the bearing 51 be difficult for deviating from.
As Fig. 4 A, Fig. 5 and shown in Figure 6, the leading section of weight block 50W and 50B is provided with upper bond part 54W and 54B and lower bond part 53W and 53B as the follower that is driven by white key 20 and black key 40 respectively.Recess 55W and 55B are installed to be formed at respectively between described upper bond part 54W and 54B and lower bond part 53W and the 53B (referring to Fig. 4 A and Fig. 5).
In this case, upper bond part 54W is identical with the position relation of vertical direction along fore-and-aft direction with upper bond part 54B, and lower bond part 53W is also identical with the position relation of vertical direction along fore-and-aft direction with lower bond part 53B.By pivot 14B is provided with more lean on than pivot 14W after, the distance between lower bond part 53B and the pivot 14B is longer than the distance (referring to Fig. 6) between lower bond part 53W and the pivot 14W.Like this, consider that the identical weight block 50 of weight of rearward end 52 moves pivotally separately, because leverage relation, when bottom fitting piece 53W and 53B were activated, weight block 50B moved pivotally by the more weak driving force of proportion gauge block 50W.
Shown in Fig. 4 A, drive the part 29 of dangling is arranged at the first half of Bai Jian 20 downwards integratedly in the mode of dangling bottom.Be fixed in the bottom that drives the part 29 that dangles such as elastic component 31W such as rubber.Elastic component 31W (lower end) is as the direct drive division of the corresponding weight block 50W of driving.More specifically, after key unit KU suitably is connected on the keyframe 10, elastic component 31W is engaged among the installation recess 55W of weight block 50W between lower bond part 53W and upper bond part 54W, so that the lower surface 54Wa of the upper surface 53Wa of elastic component 31W and lower bond part 53W and upper bond part 54W keeps in touch.
For example, when pushing Bai Jian 20, the dangle elastic component 31W of part 29 of the driving of described white key 20 drives the upper surface 53Wa of the lower bond part 53W of corresponding weight block 50W as described above, so that weight block 50W responds the motion of white key 20 and moves pivotally along button direction (this direction is the direction that the leading section of weight block 50W moves downward).On the contrary, when with white key 20 when key-press status unclamps, because the restoring force that elastic force produced of the gravity of weight block 50W self and the horizontal hinge 22 of Bai Jian 20, then weight block 50W unclamps direction (this direction is the direction that the leading section of weight block 50W moves upward) pivoting action with white key 20 along key.Therefore, in playing operation, Bai Jian 20 and weight block 50W as one man move pivotally all the time each other.
The structure of engagement relationship between the structure of the leading section of weight block 50B and black key 40 and the weight block 50B and the leading section of weight block 50W is identical with engagement relationship between white key 20 and the weight block 50W.More specifically, as shown in Figure 5, drive the part 45 of dangling is arranged at the first half of black key 40 downwards integratedly in the mode of dangling bottom (equally referring to Fig. 1).Elastic component 31B is fixed in the lower end that drives the part 45 that dangles, this elastic component 31B is engaged among the installation recess 55B of weight block 50B between lower bond part 53B and upper bond part 54B, so that the lower surface 54Ba of the upper surface 53Ba of elastic component 31B and lower bond part 53B and upper bond part 54B keeps butt.Playing operating period, effect between black key 40 and the weight block 50B and motion and the effect between key 20 and the weight block 50W and move identical in vain.
Shown in Fig. 4 A and Fig. 4 B, above-mentioned key is led the leading section 20a that portion 33 is formed at Bai Jian 20.Key is led portion 33 and is the slit crack along basic vertical direction, and has the width that is slightly larger than key guide portion 12.Being connected in key is led guide portion 32 on the front portion in the portion 33 and is integrally formed in key and is led on the and arranged on left and right sides of portion 33.When being connected to key unit KU on the keyframe 10, guide portion 32 carries out guiding functions so that key guide portion 12 is led portion 33 with key suitably engages.Lubricant applying is led on the slidingsurface of portion 33 in key guide portion 12 and key.
Shown in Fig. 1 and Fig. 4 A, the inclined surface 19 of the above-mentioned front portion that is arranged at keyframe 10 is downward-sloping towards the rear portion.When weight block 50 in the past after the side direction motion when being connected on the keyframe 10, the lower surface 50a of the leading section of inclined surface 19 butt weight blocks 50 and 50b (referring to Fig. 4 A and Fig. 5) to be limiting position vertically, described surface, thereby and with guiding weight block 50 bearing 51 of weight block 50 suitably is installed on the pivot 14 with tongue piece 56 actings in conjunction of weight block 50.Under weight block 50 is connected to state on the keyframe 10, when key unit KU moves backward from the front portion when being connected on the keyframe 10, the elastic component 31 that inclined surface 19 butts each key to be limiting this elastic component 31 position vertically, and guiding key unit KU so that the elastic component 31 of each key be fitted in the installation recess 55 of corresponding weight block 50.
In this case, identical along the cross sectional shape of the side-looking direction of each several part for inclined surface 19, described each several part is carried out the installation guiding function by lower surface 50a, the 50b of each weight block 50 of butt or the elastic component 31 of each key.More specifically, although inclined surface 19 and nonessentially on the whole width of keyboard, have uniform in-plane, and recess etc. may reside in some position, and all carry out the part of guiding functions all with respect to flushing each other.Like this, it is just fairly simple that processing is used to form the metal die of keyframe 10.
In addition, shown in Fig. 4 A, the upper end position of the lower bond part 53 of the weight block 50 that is connected is closed in inclined surface 19 position vertically.Therefore, when connecting key unit KU, elastic component 31 moves by sliding smoothly on inclined surface 19, and easily on the upper surface 53Wa of lower bond part 53W, thereby be readily incorporated in the installation recess 55 of weight block 50.In addition, the clearance C 1 between the front end of the lower bond part 53 of the rear end of inclined surface 19 and weight block 50 less than dangle along the driving of white key 20 and black key 40 part 29 and 45 along the less width in the width of fore-and-aft direction (for example, driving the width of the part 45 that dangles).Therefore, when connecting key unit KU, drive the part 29 and 45 that dangles and be subjected to guiding smoothly and can from clearance C 1, do not fall.In addition, in the process of connecting key unit KU, when just in position locating to promote slightly or during reverse keys unit KU, the slope of inclined surface 19 just allows key unit KU motion backward by the self gravitation that utilizes key unit KU.Like this, connection is oversimplified.
Now, will be explained in more detail weight block 50 and key unit KU are connected to according to the method on the keyframe 10 of this structure.At this, traditionally, corresponding in the follower of white key and the follower, obviously different along fore-and-aft direction and vertical direction with the position of the corresponding follower of the lower bond part 53 of weight block 50 corresponding to black key.Therefore, the common laborer is difficult to connect a plurality of keys simultaneously, and uses the method for work that each key is connected separately in practice.Yet, as described below, according to present embodiment, can easily connect the key unit KU of the key that wherein has a plurality of combinations.
At first, all weight blocks 50 are connected on the keyframe 10 one by one.More specifically, since the open side of the bearing 51 of weight block 50 to pivot 14 (referring to Fig. 1 and Fig. 6), so when lower surface 50a, the 50b of the leading section that makes weight block 50 slided on inclined surface 19, weight block 50 moved backward.Subsequently, bearing 51 is installed on pivot 14, so that weight block 50 is around pivot 14 pivoting actions.When finishing in a similar fashion when connecting all wt piece 50 and weight block 50 and all being in the free state, all wt piece 50 all is in the original state of pivoting action.More specifically, all wt piece 50 all is arranged in and vertically reaches the identical position of key alignment direction, and installation recess 55 is in opening in the state of front side (referring to Fig. 4 A, Fig. 5 and Fig. 6).
