Abstract

PROBLEM TO BE SOLVED: To provide a tuning hammer with which a tuning fork of fundamental tone can be hit with one hand during tuning of a piano while strings of fundamental tone of the piano are vibrated.SOLUTION: A groove is formed in a part of the handle 4 of the tuning hammer, and the tuning fork 1 and a hit spring 2 which vibrates the tuning fork 1 are fitted in the groove. Consequently, the tuning hammer can be operated and the tuning fork 1 can be vibrated with one hand. Vibration of the tuning fork 1 is amplified by the piano body to make it easy to confirm generated beats, and repetitive vibration of the tuning fork 1 can be reduced. Further, other operation can be performed with the other hand.

Description

  The present invention relates to a tuning hammer used as a tool for tuning piano strings.

  Conventionally, the tuning of a piano is performed by a tuning hammer while the tuner touches the tuning fork and confirms the vibration of the tuning fork and the beat generated by the vibration of the piano string. It is common to tune the fundamental tone of the piano string while inserting and turning the tuning pin around which is wound.

  However, the tuner holds the tuning fork with one hand and strikes it with his / her knees etc. to vibrate it, then hits the ear and listens to the vibration sound while the beat is generated from the vibration of the string of the fundamental tone of the piano. Rotate the tuning pin of the fundamental tone of the piano with the other hand and tune it with the other hand. However, the vibration sound of the tuning fork is small, and when it is attenuated, the tuning fork must be struck again to vibrate. Both hands are used in this work.

  As described above, in the conventional tuning method of the piano, the tuning fork sound is weak, so that the tuning fork must be repeated frequently by repeatedly striking the tuning fork, and the tuning fork must not be held by hand. There was a problem that it should not be.

  In order to solve the above-mentioned problems, the invention of claim 1 forms a groove 7 in a handle 4 of a tuning hammer used for tuning a piano and vibrates the tuning fork 1 and the tuning fork 1 in the groove 7. It is a tuning hammer having a structure in which a tapping spring 2 is attached to the groove 7.

  According to this structure, when the tapping spring 2 is released and the tuning fork 1 is hit, the vibration is caused by the piano body via the hammer tip 5 of the tuning hammer and the tuning pin of the string to be tuned. Can be amplified. Further, when the tuning fork 1 is vibrated again, the tuning fork 1 can be vibrated by operating the hit spring 2 with the hand holding the tuning hammer.

  According to the first aspect of the present invention, the tuning keyboard can be struck and vibrated, and the tuning hammer and the tuning fork 1 in the groove 7 can be vibrated by the tapping spring 2 with one hand. At the same time, the vibration of the tuning fork 1 is amplified by the piano body, so that it is easy to check the generated beat.

  The best mode for carrying out the present invention will be described below with reference to the accompanying drawings.

  FIG. 1 shows a tuning hammer having the structure of the present invention.

  Here, the structure of the present invention will be described with reference to FIG. A groove 7 that can accommodate the tuning tuning fork 1 and the tapping spring 2 for vibrating the tuning fork 1 is provided in a part of the handle 4 of the tuning hammer. A rubber 3 is attached to the hit spring 2 at a portion in contact with the tuning fork 1 to suppress generation of metal sound. The tuning fork 1 and the tapping spring 2 are fixed to the handle 4 with screws 6.

  Here, the operation will be described with reference to FIG. The tuning fork 1 can be vibrated by pulling the tapping spring 2 and then releasing it to strike the tuning fork 1. Here, the handle 4 is formed with a notch so that the spring 2 can be easily lifted with a finger. The vibration of the tuning fork 1 is amplified by the piano body via the hammer tip 5 of the tuning hammer and the tuning pin to be tuned to the piano.

Effects of the embodiment

  As described above, according to the structure of the present invention, it is possible to easily confirm the beat generated from the sound of the tuning fork 1 and the sound of the piano string and to operate the tuning fork 1 and the tuning hammer with one hand. In addition, since the work conventionally performed with both hands can be performed with one hand, the other hand can be handled with the other hand, so that tuning can be performed reliably and quickly.

Other embodiments

  In the structure of the present invention, the tuning fork 1 and the tapping spring 2 can be attached to the shaft 8 in the handle 4 as shown in FIG. 5, and when the tapping spring 2 is lifted and released to vibrate the tuning fork 1, a metal shaft is obtained. The vibration can be transmitted from 8 to the piano body through the hammer chip 5 more effectively.
