Description

[Detailed description of the invention] [Field of application of the invention] The invention consists of a large number of glass tubes that play each note of, for example, a major scale, arranged vertically in the order of pitch,
This invention relates to a glass tube tubular bell that is played by hitting the upper end of the glass tube with a mallet or the like.

[Background of the idea]

It has long been known that when a glassware is struck with a hard object such as a glass rod, a clear, dry sound unique to glass is produced, and in ancient times it was used by many people as a wind chime. It has become something we are used to.

However, although the tones unique to glass have been familiar for a relatively long time, using glass products such as glassware as musical instruments is limited to some individuals and hobbies. It is rarely seen except for.

The main reason for this is the relatively fragile nature of glass products.

Therefore, for musical instruments such as tubular bells, in which metal pipes of different lengths are arranged in pitch order and hung on a frame, and played by hitting the upper end of the metal pipes with a mallet, glass is used instead of the metal pipes. Simply using a pipe does not provide enough strength to withstand a strong blow to its upper end, and therefore it is not suitable for playing with dynamics and cannot be said to be sufficient for use as a musical instrument.

[Purpose of invention]

The present invention was devised in view of this point of view, and it is an object of the present invention to provide a glass tubular bell that satisfies the durability of a musical instrument and does not break even when struck with force.

[Summary of the idea]

Therefore, the gist of achieving the purpose of this invention is as follows.
A hollow thick-walled glass stopper with a hemispherical convex outer periphery is fitted and fixed to the upper end, and a small hole is drilled in the radial direction of the upper end.By hitting this head, you can play the scale. A large number of glass tubes, which are adjusted to produce each tone, are erected in an arch shape, and a hanging string passed through the small holes of the glass tubes is hooked and supported on the upper end frame part of the glass tubes. A glass tubular bell is provided with a support frame for suspending notes in the order of pitches, and a damping means for stopping the lingering sound of the glass tube by a player's operation, and the support frame is arranged horizontally at approximately the center in the vertical direction. A pair of upper and lower guide frame plates having insertion holes along which the glass tube is loosely fitted are fixed, and the vibration damping means is provided between the pair of guide frame plates so as to be movable in the front and rear direction. A damping frame plate is provided with an insertion hole into which the glass tube is loosely fitted, and is always biased rearward by a spring member; a rotating lever connected to both ends of the vibration damping frame plate, and when the vibration damping frame plate is in a rearward biased position, the insertion hole of the vibration damping frame plate and the pair of guide frames are connected to each other. The glass tubular bell is characterized in that the glass tubular bell is configured so that the insertion holes of the plate are aligned with each other.

In the figure, reference numeral 1 denotes a pair of rigid frame plates that stand apart and face each other, and the upper ends thereof are formed in a stepped shape that is lower on the front side and higher on the back side.
A first support frame plate 2 is fixed between 1a, and a second support frame plate 3 is fixed between the high step portions 1b. In addition, three grooves 1c, 1d, and 1e are spaced apart from each other vertically along the width direction of the pair of hard frame plates 1, 1, and the central groove 1d. , 1d, a vibration damping frame plate 4 connected to a vibration damping mechanism to be described later is fitted so as to be movable along the groove 1d, and between the upper grooves 1c and 1c and the lower groove 1e. ，
Guide frame plates 5, 5 are fitted and fixed between 1e, respectively. The damping frame plate 4 and the pair of guide frame plates 5, 5 are provided with an insertion hole 6 into which a glass tube is loosely fitted, and the inner peripheral surface of the insertion hole 6 is provided to protect the glass tube. Felt 7 is attached. The first support frame plate 2 and the second support frame plate 3 are each provided with a suspension device to be described later for suspending a glass tube 8, and the upper end of the glass tube 8 is attached to this suspension device. The glass tube 8 is supported and suspended. On this first support frame plate 2, glass tubes 8 that play whole tones of the musical scale are arranged vertically at approximately equal intervals in pitch order, and on the second frame plate 3 are glass tubes 8 that play half tones.
are arranged vertically in correspondence with the diatonic glass tubes 8 arranged on the first frame plate 2.

At the upper end of the glass tube 8, a thick hollow glass stopper 9 is provided with a through hole 9a as shown in FIG.
The outer circumferential portion 9c of the head 9b of the hollow glass stopper 9 is formed into a semicircular convex shape, and the outer circumferential portion 9c is adapted to be struck with a mallet or the like.

In other words, the glass stopper 9 is thick-walled and has a hemispherical convex outer circumferential surface, so even if the head is hit hard, the glass tube 8 will not be damaged and will still produce sound. becomes. Further, the outer peripheral surface of the insertion portion 9d of the hollow glass plug 9 and the inner peripheral surface of the upper end of the glass tube 8 are subjected to a co-printing process, and the hollow glass plug 9 is adhesively fixed to the glass tube 8 with an adhesive. It is designed to prevent it from coming off.

In this example, the glass tubes for the whole tone and the glass tubes for the semitone are of the same diameter, and the pitch is adjusted by changing the length. It is designed to play a range of tones from 2 to 2 octaves high.

Next, the vibration damping mechanism will be explained based on FIGS. 4 and 5.

When the hollow glass stopper 9 is struck with a mallet or the like, the glass tube 8 vibrates and produces a sound, but it is necessary to eliminate the lingering sound for performance purposes. Therefore, in this embodiment, the vibration damping frame plate 4 is moved and the glass tube 8 is pressed against the pair of upper and lower guide frame plates 5, 5 by the vibration damping frame plate 4 to stop the glass tube 8 from vibrating. The damping frame plate 4 is moved by the player rotating a lever 10 provided between the pair of rigid frame plates 1, 1. This lever 10 is formed by bending a pipe member into a U-shape, and both ends of the lever 10 are attached to a mounting plate 1 attached to the front surface of the rigid frame plates 1, 1.
