Description

  This device is a pedal device for children whose feet do not reach the piano pedal and adults with weak leg strength.

 Pianos include damper pedals, sostenuto pedals, soft pedals, etc. After hitting the keyboard, pressing this pedal creates a musical and artistic performance effect. Traditionally, pianos are made based on the performance of adults, so when a child plays, the pedal does not reach the pedal and the choice of the song is limited. Also, even adults with weak leg muscles had a burden on performance.

 Conventionally, there are piano auxiliary pedal devices that can be operated by raising the pedal, but there are things that can be adjusted only with special tools, and screws often come loose during performance. And in the children's performance competitions and presentations, the time required for changing the players was short, so the setting was sometimes nervous.

  In order to solve this problem, the present invention is designed to simplify the rigidity and height adjustment mechanism when this device is attached to the pedal of the piano body, and plans to help the convenience of the performer. Developed.

The present invention is an auxiliary pedal device for a piano having the following configuration.
(A) A hemispherical pedal is provided on the horizontal part of the inverted L-shaped L-shaped arm.
(B) A V-shaped concave portion is provided in front of the vertical portion of the inverted L-shaped L-shaped arm.
(C) A V-shaped convex part is provided in front of the vertical part of the L-shaped L base.
(D) The V-shaped concave portion of the L-shaped arm and the V-shaped convex portion of the L base can be fitted at each stage.
(E) A recess for receiving a piano pedal is provided in the horizontal portion of the L base.
(F) A pressing plate for fixing and pressing the piano pedal that has entered the recess of the horizontal portion of the L base is provided.
Furthermore, this invention provides a stopper in the horizontal part of L base.

This new device does not require any tools and can be easily set by a less powerful woman. In addition, by machining the v-shaped groove in the extension part, even if the tightening part is loosened somewhat, the force always concentrates at the center, so there is no deviation and there is no unstable element.
It can also be extended through adapters to accommodate smaller children. In addition, by setting the L pedal in reverse, it can be used for a wide range of ages, from upper grades to adults.

In addition, the shape of the place where it touches the sole is applied to the gentle semi-spherical sphere so that the ground contact surface of the sole is easy to catch so that there is no stepping off. In addition, hemispheres can be removed, so consideration is given to unnecessary players and various players.
In addition, in order to reduce the amount of vibration when the pedal is operated with this device, the user-friendliness is taken into consideration so that adjustments can be made according to each performer via a stopper.

It is an exploded view of the present invention. It is a perspective view of L type arm of the present invention, L base.

  Example 1 of the auxiliary pedal device for a piano according to the present invention will be described with reference to FIGS.

  As shown in FIG. 1, the auxiliary pedal device for a piano according to the first embodiment includes an inverted L-shaped L-shaped arm 1 and an L-shaped L base 2. A hemispherical pedal is provided on the horizontal portion of the L-shaped arm. There are two mounting parts for the hemispherical pedal in the horizontal part, which can be selected. A plurality of V-shaped groove portions 8 are provided in the vertical portion of the L-shaped arm, and a female screw portion is provided at the bottom of the groove portion 8. A plurality of V-shaped protrusions 9 are provided in the vertical portion of the L base 2 and a hole through which a screw passes is provided in the protrusion 9. The horizontal portion of the L-shaped arm 2 is provided with a groove portion 10 into which a piano pedal 6 is inserted. Further, a female screw portion for screwing the pressing plate 4 for pressing the pedal 6 is provided. Two stoppers 5 as shown in FIG. 1 are provided in the horizontal portion in the vicinity of the vertical portion.

  Next, a method of using the piano auxiliary pedal device according to the first embodiment will be described.

  The hemispherical pedal 3 is screwed and attached to the horizontal portion of the L-shaped arm 1, and the female screw 7 can be selected in proportion to the length of the player's foot. Then, the L-shaped arm 1 is temporarily fixed to the L base 2 for the time being. Then, the pedal 6 of the piano body is inserted into the groove portion 10 of the piano auxiliary pedal device, the pressing plate 4 is placed from above, and the pedal 6 is firmly fixed with the fastening screws 11 at both ends.

  Next, the performer sits down on a piano chair, puts on a predetermined performance form, puts a light foot on the hemispherical pedal 3 of the piano auxiliary pedal device, and after confirming the stepping foot, engages the groove 8 and the projection 9 The convenient place is adjusted and fixed with the screw 12. Even if the screw 12 is not tightened firmly, the device has a V-groove mechanism, so it does not shift during the performance because it has a force in the center. Further, the stopper 5 has a function of arbitrarily adjusting the swing width to the floor of the stage.
