A bowl-shaped sounding part and a hammer part, which is a sounding operation part provided on a projecting part formed to project outside the peripheral edge of the support part and sounded by striking the sounding part with a biasing force of a spring, is there. Since the lower surface of the support portion contacts the upper surface of the pedestal portion while being constantly pressed by the urging force of the spring or the like, the sounding operation portion together with the support portion is fixed with respect to the pedestal portion. While it can be forcedly rotated when the above force is applied, it is configured so that the contact surface will not slip and rotate unintentionally at all times such as when riding a bicycle.

[0003]

[Problems to be solved by the device]

 The above-mentioned conventional example has a drawback in that the operating part and the operating part unexpectedly rotate with respect to the pedestal part while riding a bicycle due to a decrease in the urging force of the spring and wear of the contact surface. There was a problem of low. Also, since the cylinder axis rotates around the center axis and displaces the cylinder axis with respect to the pedestal part, the hammer, which is the sounding operation part along with the support part, is planar with respect to the pedestal part, that is, two-dimensional. Since it can only be rotationally displaced, it is not possible to vertically move the hammer to the pedestal part so that the driver may not be able to move the hammer to a position where it can be easily operated. there were.

An object of the present invention is to solve the above-mentioned problems and the like, and to provide a bicycle bell which has high durability and which can displace the sounding operation part in three dimensions, that is, three-dimensionally with respect to the pedestal part. The purpose is to

【Example】

 Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings. Here, FIG. 1 is a side view showing a main part in a longitudinal section, and FIG. 2 is a front view. Further, FIG. 3 is a side view showing a longitudinal section of a main part of the modified example.

As shown in FIGS. 1 and 2, the bell 1 is a pedestal portion 2 made of synthetic resin, which is fixed to a handle (not shown) on the vehicle body side, and is connected to the pedestal portion 2. , A support portion 4 made of synthetic resin having a central shaft 3 on the side opposite to the pedestal portion 2, a metal bell 5 as a sounding portion supported at the tip of the central shaft 3, and the supporting portion 4 And a hammer 6 which is a sounding operation unit for striking the bowl-shaped bell 5 to generate sound.

As shown in FIGS. 1 and 2, the pedestal 2 is integrally formed with a band 8 wound around a handle and fixed by tightening with a tightening screw 7. A bearing 9 having an inner shape of a spherical partial shape is formed, and a through hole 10 extending laterally from the bearing 9 and opening to the outside is formed. Into this through hole 10, a lock bolt 12 having a male spiral, which is screwed into a nut 11 having a female spiral arranged in the middle thereof, can be advanced and retracted, and the tip of the lock bolt 12 reaches the bearing 9 when it enters. I am doing it. The through hole 10, the nut 11 and the lock bolt 12 constitute a lock mechanism. Reference numeral 13 in FIG. 1 denotes a nut having a female spiral with which the tightening screw 7 is screwed.

As clearly shown in FIG. 1, the support portion 4 has a disk shape, and the central axis 3 and the ball axis 14 having a partial spherical shape are provided on the front and back sides of the center thereof in a protruding manner. The protrusion 4a for fixing the hammer 6 is formed by protruding a part of the peripheral edge thereof. The ball shaft 14 has substantially the same shape and size as the inner shape of the bearing 9 of the pedestal 2, and is slidably fitted inside the bearing 9.

As clearly shown in FIGS. 1 and 2, the bowl-shaped bell 5 has a bowl-like shape and is inserted into the top hole 15 and a metal bell body 16 having a top hole 15 at the center. The cap 17 has a cylindrical shaft portion 17a that is capable of being tightly fitted to the tip of the central shaft 3, and a collar 18 that is tightly fitted to the outer periphery of the shaft portion 17a. The collar 18 holds the edge of the top hole 15 of the bowl-shaped bell 5 with the inner portion of the cap 17 from above and below to prevent the bowl-shaped bell 5 from rattling with respect to the central axis 3 and the center axis 3. To do so.

As shown in FIG. 1 and FIG. 2, the hammer 6 has a winding spring 19 having a base end fixed to the protrusion 4 a at the periphery of the support portion 4, and a hammer 6 fixed to the upper end of the winding spring 19. The finger hook 20 is provided with a hitting point 20a facing the side of the bell 5 at a predetermined interval. In this hammer 6, when the finger hook 20 is repelled, the coil spring 19 swings due to its resilience and strikes the bowl-shaped bell 5 at the striking point 20a to generate a bell sound.

Next, a method of using the bicycle bell 1 will be described. First, the bell 1 is fixed by winding the band 8 of the pedestal portion 2 around the body side of the bicycle, for example, the steering wheel, and tightening the tightening screw 7. Subsequently, with the lock bolt 12 loosened, the hammer 6 is displaced together with the support portion 4 so that the driver can easily flip the finger hook 20. At the time of this displacement, the support portion 4 is not only a two-dimensional rotational displacement on a plane parallel to the pedestal portion 2, but also a vertical displacement that raises or lowers the hammer 6, that is, a three-dimensional displacement. The rotational displacement can be interwoven, and the driver can displace the hammer 6 to a position where it is easy to operate. Therefore, for example, the bicycle bell 1 can be displaced to a position where the hammer 6 can be easily operated even if the bicycle 6 is fixed to a position where the hammer 6 is conventionally difficult to operate, such as a curved portion of the handle.

Next, a modification of the above embodiment will be described with reference to FIG. In the description of this modified example, detailed description of the same configurations as those of the above-described embodiment will be omitted, and only the same reference numerals as those of the above-described embodiment will be given to the corresponding components in FIG.

The bicycle bell 50 of this modified example is different from the above embodiment in that the distance between the pedestal portion 2 and the support portion 4 is larger than that in the above embodiment. With such a configuration, there is an advantage that the vertical displacement amount for raising and sinking the hammer 6 with respect to the pedestal portion 2 becomes large.

It should be noted that the present invention is not limited to the above-described embodiments and modifications, and for example, the lock mechanism may be changed to a mechanism different from that of the through hole 10, the nut 11, and the lock bolt 12. Good. Further, the sounding operation section is fixed to a rotary cylinder rotating around the central axis, instead of the hammers 6, and an arm configured to strike the inside of the bowl-shaped bell with a striking section at its tip, Not only may it be changed to a so-called pull lever type in which the rotary cylinder and the rack and pinion mechanism are connected to each other, and the end portion is projected outward, and the sounding section can sound by operating the sounding operation section. If it is one, it may be changed to a different one from the bowl-shaped bell 5.
