BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bicycle bell.

[0002]

2. Description of the Related Art Conventional bicycle bells are classified into a rotary inner hitting type that rotates a hitter in the bell and a fixed outer hitting type that repels a hitter disposed outside the bell. Emits a continuous sound called chiririririn, and the latter emits a single sound called chin. But in any case, the sound quality is hard, the pitch is similar,
Few attempts have been made to change this.

The present inventor has studied on changing the tone, sound quality, pitch, etc., by changing the material and shape of the bicycle bell so as not to give a pedestrian an uncomfortable feeling. As a result, it has been found that by forming a lightening hole in the bell or changing the striking position, it is possible to change the turbidity of the tone, the weight of the sound quality, or the pitch of the sound.

[0004]

SUMMARY OF THE INVENTION The present invention has been made based on the above findings, and it is an object of the present invention to make it possible to extend a selectable range of sound of a bicycle bell.

[0005]

In order to solve the above-mentioned problems, the present invention has a bell body 3 formed of a single member formed of a metal and having a substantially bowl shape, and supports the bell body 3 at the center.
And when the area near the periphery is hit with a hammer 5
In a bicycle bell that emits a tapping sound, a large number of lightening holes 6 are provided through the bell body 3 in order to change the tone and volume of the tapping sound.

BRIEF DESCRIPTION OF THE DRAWINGS FIG.

FIG. 1 (a) shows only a bowl-shaped bell body 3, and the bell body 3 has a large number of lightening holes 6 formed of circular through holes at regular intervals in a portion near a peripheral edge 7. This is an example in which the film is formed. FIG. 2B is the same as the bell of FIG. Contrary to the lightening hole 6, a large number of lightening holes 6 are uniformly formed almost entirely except for a portion near the periphery.
FIG. 2B shows a state in which the bell main body 3 is attached to the core column 2 by the attaching means 4.

The core column 2 shown in FIG. 1B is established at the center of the dish-shaped base material 8, and the ring-shaped mounting member 1 is attached below the dish-shaped base material 8. The bell main body 3 has a fitting member 9 made of resin on the lower surface of the central part, and the upper end 10 of the core column 2 is securely fitted and attached to the downward hole. The fitting member 9 and the upper end portion 10 of the core pillar fitted to the fitting member 9 constitute mounting means 4 for the bell body 3. The dish-shaped substrate 8 is made of a resin molded product, and therefore the mounting member 1 is also integrally formed. However, a ring-shaped part is provided with an openable and closable separating part 11, and a screw 12 for closing the separating part 11 is used. Or the pipe material P around the handle.

A striker 5 for striking the bell main body 3 is attached to the dish-shaped substrate 8 so as to protrude to the outer periphery of the same.
It is arranged close to the outer peripheral surface of the bell body 3 via the pedestal 13 and the coil spring 14. Note that the striker 5 may be formed to be rotatable around the bell body 3.

FIG. 2 shows an example in which a bell body 3 having a hemispherical shell shape is provided. The bell body 3 shown in FIG. 2 (a) has a vertically elongated wall in an intermediate portion away from the peripheral edge 7 and the center. Hole 6
Are formed radially and equidistantly, and a screw is provided as a mounting member 1 below the central core column 2 so that it can be directly mounted together with the batter 5 into a mounting hole Q formed in the pipe material P. it can. FIG. 2B shows an example having no dish-shaped base material. The core column 2 is directly erected on the upper pedestal 15 of the ring of the mounting means 4. A batting 5 is also provided by utilizing the mounting portion of the core pillar, and the batting 5 is directed to the side, and taps the peripheral edge 7 of the bell body 3 from below to above.

The operation of the position and number of the lightening holes 6 formed in the bell body 3 is as follows. Generally, the pitch of the sound changes to a lower side by the opening of the lightening hole 6, and the sound quality becomes lighter as the lightening hole 6 is provided closer to the center portion, and conversely, the lingering sound increases when the lightening hole 6 is provided near the periphery. . Further, when a vertically long lightening hole 6 is provided in the middle portion as shown in FIG. 2A, the sound quality is reduced and the finish is increased. Therefore, it is possible to provide a bicycle bell having various timbres and sound qualities based on the above knowledge. The sound intensity (volume) gradually decreases as the number of the lightening holes 6 increases. Further, the material of the bell body 3 is preferably aluminum, which has an advantage that the weight is reduced by removing the thickness.

[0012]

Since the present invention is constructed and operates as described above, the bell body 3 formed of a single member is transparent.
Sound and light sound quality with a number of lightening holes 6.
Comb, the colorful sound of a bicycle bell to expand the range of pitch, also can increase the commercial value, especially by moderate reduction of light sound quality and volume, such feel uncomfortable or surprised the pedestrian or the like Kusuru It has remarkable effects such as being able to do.
