Description

The present invention relates to a prepared system with piano large roof opening and closing control (background art).

  In the past, the grand piano's large roof was heavy, and it was opened and closed by its own hands, and it was an internal performance technique that directly manipulated the frame and strings inside the piano. There was also a prepared piano that produced different sounds from ordinary pianos when keyed with various objects such as bolts, rubber, and wood chips in the piano strings.

No. Sho-58-62393 Grand Piano Sound Reduction Device (Disclosure of Invention)
(Problems to be solved by the invention)

This has the following drawbacks: (a) The grand piano roof is very heavy, and it takes a lot of time and effort for children and powerless women to open and close, and it is very dangerous.
(B) Hands and other objects may be attached to the piano strings, or foreign objects may be directly manipulated inside the strings. This will not only adversely affect the precise adjustment of the original piano, but also dirt may cause rust and worms. The cause (c) Japanese Patent Application No. 58-62393 is similar to the chute portion of the present invention. However, as a drawback, the apparatus is directly attached to the piano frame. Since the so-called steel frame of the piano is an important part of the sound of the piano sound, it is better not to touch any device.
Because the damper wire to reduce the sound was attached from the side, the sound reduction effect was difficult enough to press the string directly with your finger, and the damper sound stop position was not completely uniform overall. There is no problem when stopping the string being played, but when the pressure on the damper's string is relaxed, that is, when the sound is reduced, the harmonic partial sound is emphasized depending on the position of the damper. Although the partial sound is hardly generated at the end of the string 42a, the partial sound gradually increases when the damper is moved to the central portion of the string 42a.
If the performer doesn't need this part, it will quickly become unbearable noise. Although this device is detachable, it takes time and effort to tune and repair the piano of the main body unless it is designed so that all devices can be easily detached.
(Means for solving the problem)

  Invented a device that attaches an arm with a high-pressure gas cylinder to make it easy to open and close the grand piano roof, and designed to make it easy to attach and detach the device.

  The design is such that it does not contact parts such as the piano sound board 31, the frame 47, and the side plate 1 a that seem to be related to sound. The wire that supports the chute block in the chute part of the prepared system is designed to be perpendicular to the string. Then, even if you shoot the string with a little force, you can obtain a sound-stopping effect as if you pressed the string directly with your finger.

The end of the string 42a is more effective to shoot the string 42 a little, but moving the shoot block closer to the center of the string is effective to make the sound completely deadlocked, but the extra part The generation of sound will increase, the size of the cushioning member matched to the length of the string 42a and the crimping device for stopping sound will be unified throughout, and finally the precise adjustment according to the player's preference To complete.
(The invention's effect)

Even if it is attached to a precision-adjusted piano, the negative effects can be kept to a minimum, so that more people can enjoy the sound of the prepared piano. The arm with a high-pressure gas cylinder not only makes it easy to open and close the large roof, but also serves as a safety measure for the prepared system.
(Best Mode for Carrying Out the Invention)
(Implementation column 1)

Hereinafter, embodiments of the present invention will be described. FIG. 1 is an overall view of the present invention.

  The metal fittings 4 and 5 for attaching the center rail 2 are attached below the music stand holders 7 and 8 of the left and right pianos. At that time, the music stand holders 7 and 8 are removed. The metal fitting 4 has a bent portion 4d and a bent portion 4a on the left side on the left side, and a bent portion 46 from the front side to the back side. The right metal fitting 5 is attached so that it is in close contact with the upper part, and the lower part is bent 5a, the lower part is bent from the front to the rear part 5b, and 5b is attached so as to be in close contact with each other. Attach with. You may attach using the screw hole of the piano music stand holder.

  The mounting bracket 4 is provided with a motor flower arm 6 insertion hole 4F at the center rail mounting portion 4a, and a music stand arm 58 insertion hole 4F at the bent plate 4d on the front side.

  The center rail 2 is attached by fixing the 4a portion of the left mounting bracket 4 and the screw hole 2a with screws, and by fixing the 5a portion of the right mounting bracket 5 and the screw hole 2b of the center rail 2 with screws. The center rail 2 is gradually thinned from the left to the right, and an arm fixing screw hole 2E provided with an arm mounting metal back 2c and an arm mounting metal front 2d and a high pressure gas cylinder mounting metal 2H are provided on the left side. The arm back 9 is attached to the metal back 2c of the center rail 2 with the metal pin 9a, the arm front 10 is attached to the metal front 2d of the center rail 2 with the metal pin 10a, and the high pressure gas cylinder 14 is attached to the metal 2H of the center rail 2 with the spherical pin 15 Install.

  The 9b portion at the back of the arm 9 and the 10b portion at the front 10 of the arm are parallel to the center rail 2, and are slightly bent from the middle toward the back. A rotary base 13c of the arm head 13 is attached to the right end of the arm by a pin 12, and the tip of the high-pressure gas cylinder 14 is also attached to the pin so that the arm head can be rotated with respect to the arm head attaching pin 12. Install. The foot of the high-pressure gas cylinder is attached to the center rail with a high-pressure gas cylinder metal 15, and this part is a spherical pin so that the arms 9 and 10 can move freely.

  The fixing screw 11 is inserted from the central portion of the arm 10 and attached to the center rail screw hole 10 to prevent the high pressure gas relinder 14 from running away when not in use. A spring 10b wound around the fixing bolt 11 is mounted between the arm 10 and the center rail. This is because the high-pressure gas cylinder, which is the lifting force of the arms 9, 10, does not operate unless it is lifted up a little.

  The arms 9 and 10 move so as to be lifted by the high-pressure gas cylinder 14 as shown in FIG. 7, and when the arms 9b and 10b lift the piano roof 16 as shown in FIG. Further, since the shock-absorbing member 13a having good sliding property is bonded to the arm head 13, the large roof 16 is not damaged.

  Next, in FIG. 10, which is the mute portion of the prepared system, the mute rod 24 is attached to the 2F portion of the center rail 2 with the bearing 18 and attached to the partition of the piano frame with screws 18b as shown in FIG. Since a cloth woven with felt is pasted at a position 18 a in FIG. 9, the mute rod 24 can freely rotate with respect to the bearing 18. The bearing 18 is mounted on the left and right sides of the arm 24a at the left end 24c of the mute rod. To reinforce this part and prevent left and right displacement.

  A support 25 for moving the mute bar 35 is installed on the mute rod 24. The support 25 is fixed to the mute rod 24 with screws 25c. And since the arm 25b is inserted with respect to 25a, it fixes with the screw | thread 25d in the place which adjusted the length. The mute bar 35 is also fixed with the screws 25E of the support 25. The mute bar 35 is installed at two locations on one mute bar 35, and is installed in accordance with the partition of the piano frame as shown in FIG. The spring 25G with respect to the support 25 and the buffer member 25H are attached to the support 25 on the second floor, and this may be selectively attached.

  The mute bar 35 is attached according to the partition of the piano frame 47 of the main body, so the mute bar is determined by the number of partitions, and the number of mute bars is determined by the piano to install the bearing 18 of the mute rod 24 between the partitions. The number of bearings changes.

  A hole 35b is formed in each mute bar 35 in accordance with the piano string 42, a mute wire 40 is inserted, and a mute block 41 is fixed to the lower end with a mounting screw 41a. A felt 41b is bonded to the mute block 41. As shown in FIG. 10, the mute wire 40 is fixed with the screw 35a of the mute bar 35 so that the mute block is located on the back side of the graph 43. The mute block 41 is shown in FIG. When the space becomes narrower as shown in FIG. 20, which becomes smaller than that for the high sound shown in FIG. 14, the string becomes shorter.

  The mute rod 24 has an arm 24 at the left end and two pawls 24b at the tip thereof, which are attached so as to catch the lead 45b at the tip of the pedal wire 45a.

  The pedal wire 45 has a structure in which the wire 45a is inserted into the pedal wire hose 45F. The lead 45b of the wire 45a is attached to the pawl 24b of the mute rod 24 so that the pedal wire hose 45F can be stopped under the pawl 45E of the pedal wire support 45d. A spring 45c is attached between the mute rod 24a and the wire support 45d so as to be wound around the wire 45a. In FIG. 10, the mute wire 40 can be adjusted by bending the wire to match the string as in 40a.

  The pedal wire 45 is connected to the wire pedal from 45J to the pedal wire 45I in FIG.

  In FIG. 21, the wire pedal 46 is attached to the attachment metal 46a by attachment pins 46b. The mounting pin 46b allows the pedal 46 to perform seesaw motion. The pedal spring 46L is attached to the pin 46c of the attachment metal 46a. A pedal height adjusting screw 46F is attached to the rear side of the pedal 46, and the lower end of the screw 46F comes into contact with a buffer member 46M such as a felt of the screw support 46I. Then, a hole slightly larger than the screw 46G is formed after the screw 46F of the pedal 46, and the screw 46G is attached to the screw support 46I below from the hole. A large washer is bonded to the screw 46G, and a cushioning member 46H such as felt is attached to the pedal 46. It is a mechanism to adjust the pedal exerciser. A slipper 46N such as rubber is mounted under the pedal 46. The position of the pedal 46 can be freely changed. If the nut 460 which welded the disk-shaped iron plate to the lower part of the screw 46F is attached, it will become difficult to damage the felt 46M.

  A wire hose screw 45H is attached to the pedal wire 45 at the position of the pedal 46K, and a wire hose nut 45G is attached thereon. This is an adjustment of the length of the wire hose 45F. The lead 45b is attached so as to be caught on the claw 46J of the screw support 46I.

  This mute unit is controlled by the wire pedal 46. By stepping on the pedal 46, the mute rod 24 rotates and pushes down the mute wire 40 via the support 25 and the mute bar 35 so that the felt 41b of the mute block 41 contacts the string. Also, the contact strength can be adjusted by the petal 46. The piano player can freely make sounds that are bothered and stagnant. Moreover, since the mute bar and the mute wire can be adjusted, it is possible to partially operate the mute bar and the mute wire.

  Next is the Honky Tonk Club. The mute wire 40 in the mute portion is removed, and the honky tonk wire 48 is inserted. As shown in FIG. 17, a part of the mute unit is used as it is.

  The piano string 42 has a minimum pitch of two as it goes to the treble part, and the middle and treble parts are all three. The honky tonk wire 48 is used in places where there are two or more strings 42. One place has two strings and one place has three strings on the left or right. A little further, the string of the graph 43 vibrates and is set as shown in FIG.

  When the wire pedal 46 is operated, the mute bar 35 is lowered and the honky tonk wire 48 is in contact with one of the two strings, and when the three strings are in contact with one, only the string with which the honky tonk wire 48 is in contact, The vibration length is a little shorter, and the sound sounds crazy. When the honky tonk wire comes into contact with the string as shown in FIG. 19, the cushioning member 48a such as a felt prevents noise. Note that how much the honky tonk wire 48 is brought into contact with the graph 43 is adjusted according to the player's preference while listening to the sound.

  A piano string is strong in tension, and a honky tonk wire 48 is brought into contact with the string at a right angle in order to sever vibration of the string on the way. The honky tonk wire 48 can be used as long as possible. In addition, it is more effective to attach the gram weight 73 as shown in FIG.

  Next, FIG. 24 shows the harmonic part. A plurality of bearings 49b for attaching the harmonic rod 49 are attached to 2G of the center rail 2 in accordance with the partition of the frame 47 of the piano body. Since this bearing 49b has a cloth 49c knitted with felt on the inside, the attached harmonic rod 49 can freely rotate. Also, bearings 49b are mounted on the left and right of the pawl arm 49a. To prevent this part from shifting to the left and right.

  A bearing 51 for attaching the harmonic bar 50 is attached to the side surface 2G of the center rail 2. In the case of FIG. 1, four bars 50 are attached to each of the piano frames 47 as many as two partitions. As shown in FIG. 20, the harmonic bar 50 can be freely rotated because the cloth 51b of the bearing 51a is affixed with a felt braided cloth. The bearing 51 of the harmonic bar 50 is shaped so as to fit under the center rail 2. In addition, as shown in FIG. 24, the fixing ring 68 is fixed so that the left side of the bearing 51 of one bar is set to the left, the right side is set to the right, and is tightened with a screw 68a.

  The harmonic bar 50 is aligned with the strings of the piano, and the harmonic wire 50a is inserted into the hole 50c. The weight 70 is inserted on the opposite side of the bar 50, and the screw 70a is felt to the fixing harmonic wire 50a. The harmonic block 52 provided with the buffer member 52a is inserted, and the screw 50b is for fixing. Attach these as many as the number of strings. The weight 70 and the block 52 can move freely. The weight 70 is for improving the balance of the harmonic bar 70 so that the movement can be easily controlled, and may be selectively attached.

  In order to control the movement of the harmonic bar 50, a harmonic bar support 54 is attached and fixed with screws 54a. On the other hand, the harmonic rod support 53 is attached to the harmonic rod 49, and the portion 53b of the support 53 fixed by the screw 53a and the portion 54b of the support 54 are in contact with each other so as to be cut. A cushioning member such as a felt is attached to the side where there is no notch so as to prevent noise from being transmitted. The support is attached to the harmonic bar 50 attached to the partition of the frame 47 one by two.

  A pawl 49a is attached to the left side of the harmonic rod 49 as viewed from the keyboard side of the piano body, and the lead 55b of the harmonic pedal wire 55a is attached. The pedal wire hose 55E is attached so as to be stopped by a harmonic wire support 55d attached to 2G of the center rail 2. A spring 55c is attached between the pedal wire support 55d and the claw 49a of the harmonic rod so as to be wound around the pedal wire 55a.

  The harmonic pedal wire 55 is connected from the portion 55F in FIG. 24 to 45I of the pedal wire 45 in FIG. 21 and connected to another wire pedal 46. The movement of the harmonic bar 50 is entirely controlled by the momentum of the wire pedal 46.

  The piano player sets the harmonic block 52 on a half or a quarter or an eighth of the string of the piano that uses the second wire pedal 46 to operate the harmonic part. This can be used in part to determine the player's preference. When the pedal is depressed so as to slightly stimulate the strings 42 when the piano strings are played, the partial sound of the harmonics of the strings 42 is emphasized, and a sound different from that of a normal piano is obtained. In addition to the harmonic block 52, an iron plate, a piece of wood, rubber, a piece or the like may be attached as desired.

Next is the vibrato section. The center rail mounting bracket 4 has a motor flower 56 mounting metal 4F, so that the 6a portion of the arm 6 is bent at a right angle so that it can be inserted here, or a pipe narrower than the mounting metal 4F is mounted at a right angle and inserted into the 4F. The motor flower arm 6 can freely rotate about the mounting metal as a fulcrum. Furthermore, since the arm 6d portion is inserted into 6b and fixed with a screw 6c, the length of the arm 6 can be freely adjusted. A motor flower 56 is attached to the tip 6F of the arm 6.
The arm 6b may be inserted into the arm 6d.

  The motor flower 56 has a rotary table 56b mounted on the motor 56a, and the rotary table 56b has a hole 56c that can be attached at various angles so that the blade wire 56d can be inserted. A variety of blades 56E are attached. The rotation speed of the motor 56a is controlled by the volume pedal 57 in FIG. 30. When 57a is below, when the power is off and 57b is slightly lowered, the power is turned on and the voltage is increased and the motor rotation speed is increased. It is like that.

  The volume pedal 57 is provided with a non-slip 60c such as rubber, so that the position can be freely changed. The electric wiring 6E of the motor flower 56 passes through the arm 6 and exits from the arm 6a. The portion 6F of the electric cord 6E in FIG. 27 continues to the portion 57d of the volume pedal 57 in FIG.

  When a piano player operates the volume pedal 57 to rotate the motor 56a, vibrato is applied to the sound of the piano. The number and shape of the blades 56E and the position of the motor flower can be freely changed according to the player's preference.

  Next is the piano music stand for this system. A music stand arm insertion hole 4E is provided in the front plate 4d of the center rail mounting bracket 4. When the pipe 58K of the music stand arm 58 is inserted into the hole 4E, the music stand arm 58 freely moves in a rotatable manner with the attachment hole 4E as a fulcrum.

  In FIG. 28, the music stand arm 58 has a mounting arm 58E and a mounting arm 58d attached to the mounting support 58a by two screw pins 58H. The upper arms 58E and the lower 58d are attached to the intermediate support with screw pins 58H. The upper 58F and lower 58G of the music stand arm are attached with two screw pins H from the intermediate support, and the upper 58F and lower 58G of the music stand arm can be attached to the music stand support 58c with two screw pins H. Further, the spring 58P is mounted from the pawl 58L of the arm 58E to the pawl 58M of the arm 58d, and the spring 58P is mounted from the pawl 58N of the arm 58F to the pawl 58D of the arm 58G.

  These two springs 58P oppose the entire weight. The screw pin 58H may not be tightened more strongly than necessary.

  In FIG. 29, the rotating metal 60a is mounted on the rear side of the music stand 59. The angle of the music stand 59 is adjusted with respect to the music stand support 60 and fixed with screws 60b. The music stand support 60 is inserted into the holder 58I of the arm music stand support 58c of the music stand arm 58, and the right and left inclination and the distance between the music stand 59 and the music stand support 58c are adjusted and fixed with screws 58J.

  The piano player can move the music stand 59 freely, and the angle and the inclination of the music stand 59 are not changed.

  The treble part of the piano does not have the graph 43 as shown in FIG. 20, and instead, the positions where the mute block 41 which is the bearing part 47a of the frame 47 and the string at the tip part of the honky tonk wire 48 are in contact with each other. In order to provide unity in the same manner as described above, the wire is bent toward the bearing 47a and the wire guide holder 69 shown in FIGS. 15 and 16 is required.

  The mute bar 35 of the piano treble part removes the fixing screw 25E of the mute support 25 and attaches the bushing cross 25F. The mute bar 35 can rotate. A fixing ring 68 is attached to the left and right mute bars 35 at the tip of the arm 256 of both mute supports 25 to prevent the mute bars from shifting to the left and right.

The wire guide holder 69 is fixed to the center rail 2 with a screw 69b. The screw hole 69E of the mounting screw 69 of the wire guide holder 69 is elongated horizontally, so that the left and right positions can be adjusted. There is a wire bushing 69d in the wire hole 69G. This is a cross or plastic. Use a screw that doesn't make noise by pushing down the screw 69C on the side 69F of the wire guide holder 69. Since it is attached so as to be pushed in and there is no hole on the side surface 2F of the center rail, the wire hole portion of the wire guide holder is distorted toward the front when it is tightened firmly. Also, if the screw 69C is loosened, it will return to the back side, so that it becomes an adjusting screw before and after the wire hole. Therefore, a shape memory alloy is suitable for the material of the wire guide holder 69.
(Example 2)

  34 and 35, felt is pasted on the back side 61a of the bracket 61 for attaching the mounting bracket of the center rail 2, and felt is also pasted on the back side 62a of the adapter bracket 62 in accordance with the shape of the music stand holder 8. . Attach the adapter bracket 62 so that the mounting bracket 61 is covered from above, and tighten the adapter bracket 62 with screws in the screw holes 61b and 61c. The felt does not damage the piano. Similarly, affix a felt on the back side of the adapter bracket 64 and the mounting bracket 63, attach the adapter bracket 64 and attach the mounting bracket 63 from above, and tighten the adapter bracket with screws through the screw holes 63b and 63c. And attach.

  As for the music stand holder 66 as shown in FIG. 36, a pole 66a inserted in a U-shape has a hole 65b at the pole as in the adapter fitting 65, and a felt is stuck on the back. The adapter fitting 62 is attached to the music stand holder 8 so that the adapter fitting 62 is covered from above, and the adapter fitting 62 is tightened so as to press the adapter fitting 62 from the screw holes 61b and 61c.

  This method is used when the music stand holders 7 and 8 cannot be removed or are not desired.

  Next, a rubber 67c is applied to the inside of the ring, which is a wire fixing ring 67, and the wire and mute bar are fixed with a screw 67a opened so that the hole 67b contacts the inside of the ring.

  As shown in FIG. 39, the mute bar 35 can be individually adjusted so that the wire can be attached without making a hole, and such spare parts are often required for actual attachment.

  As shown in FIG. 40, the link 67 can be directly attached to the mute rod 24. Here, the wire guide holder 69 is required because of the high sound part. Therefore, instead of the wire hole 69G, the roller 69H is mounted. The wire 40 fixed to the ring 67 by the rotational motion moves downward while contacting the roller 69H, so the wire 40 bends little by little. . In all the high-pitched parts of the piano, the roller 69H relaxes the repulsion resistance of the bending wire 40 even in such a state.

  If the fixing ring 71 with the wire holder 72 is used, the hole 69G of the wire guide holder 69 can be used. Fixing ring with wire 40 or 48 inserted into wire hole 72b and fixed with screw a, wire holder 72 with pin 72d, mute rod 24 fixed with screw 72a, pin hole 71b and pin hole bushing cross 71c 71. The pin 72d of the wire holder 72 is inserted into the pin hole 71b of the fixing ring 71, and a set screw or a nail 72F is attached.

  In FIG. 19, the gram weight 73 having the screw 73a and the hole 73b is a weight indicating the number of grams, and is inserted into the portion of the mute wire 40 or the honky tonk wire 48 that protrudes from the mute bar 35 and fixed with the screw 73a. . This is actually installed and used as desired. As the number increases, the overall weight also increases. Therefore, it is necessary to attach the springs 25G for the supports 25 to all the supports 25.

  A single mute block 41 and honky tonk wire 48 actuation method is also required at the player's preference. As shown in FIG. 44, it can be mounted individually. The support set 74 has a tail 74b attached under the main body 74a, a spring 74c provided on the tail 74b, and a spring button 74E with a buffer member 74d attached thereto. A wire holder 74G having a hole 74F for inserting a wire and a wire fixing screw 74M is inserted into the hole 74I of the support distal end portion 74H, and the screw 74L is fixed after determining the angle of the wire. The length of the support 74N can be adjusted by inserting it into the support body 74a, and a support hole 74O to be fixed with a screw 74K is inserted into the mute rod 24 and fixed with a screw 74J at a required place.

  The single support set 74 can be attached from one place to the whole. As shown in FIG. 45, the spring 74c attaches the gram weight 73, and the wire makes it easy to control the operation even if the wire becomes heavy.

  The two bearings 18 and the bearings 49b attached to the left and right of the arm 24a of the mute rod 24 and the left and right of the arm 49a of the harmonic rod 49 are for reinforcement and prevention of left and right displacement. For this reason, if the screw holes of the respective bearings are elongated to the left and right, the position can be finely adjusted during actual mounting.

  The packing 75 is bonded instead of the bushing cloths 18a and 49c of the bearings 18 and 49b, and the packing 75 is also bonded to the inside of the fixing ring 68. The material of the packing 75 is preferably made of plastic that is not easily deformed, slides well, and does not generate noise when in contact with metal, and is bonded so that it protrudes slightly as shown in FIGS. To prevent side slipping, no noise is generated when touching, and sliding is good.

  A copy sheet 76 made by mixing phosphorescent agents and a musical score required for the music stand 59 of the present invention can be copied to the copy sheet 76 to perform in a dark place.
