Description

[Detailed explanation of the idea] This invention relates to a device for striking a bicycle bell.

In conventional bicycle bell striking devices, the pendulum and bell striker are all made of metal, which requires a lot of man-hours to manufacture, and the parts are made of metal, resulting in relatively high material costs, making it an economic disadvantage that it cannot be produced at a low price. There is.
This proposal was made with the aim of resolving this disadvantage.

The present invention will be explained by the embodiment shown in the drawings.
A pinion 4 fixed to the bottom surface of the center of a seat plate 3 made of synthetic resin is loosely fitted onto a support shaft 2 set up in the center of the base 1, and support pieces 5 are provided upright facing the upper surface of both ends of the seat plate 3. A metal hammering rod 8 formed of a small iron strip of the required length, in which a long hole 6 having a required width is provided in each of the holes, and a horizontal hole 7 through which the support shaft 2 passes is provided in the center.
The outer ends of the striking bell rods are each formed into a sword tip 9 with a specific oblique side, and each of the long holes 6 has an elastic control piece 1 for suppressing the vertical movement of the striking bell rod 8.
0 is provided, and the pinion 4 is connected to the sector gear 13 formed integrally with the puller 12 via the intermediate transmission gear 11, and is provided at the inner center of the bell 14 on the upper threaded portion of the support shaft 2, similar to a normal bell. This is a female screw hole that is screwed together.

Since the present invention is constructed as described above, the handle 12 is operated in the same way as a normal bicycle bell, and the pinion 4 loosely fitted onto the support shaft 2 is driven via the sector gear 13 and the intermediate transmission gear 11. Then, pinion 4
The plate-shaped hammering rod 8, which is installed on the seat plate and whose both ends are fitted into the long holes 6 of the support piece 5, rotates in the direction of rotation of the seat plate. Accordingly, it moves laterally due to the action of centrifugal force, and the hammer-point-like oblique side of the outer end strikes the striking protrusion projecting inward of the bell, which is on the rotation path, thereby striking the bell. At this time, both ends of the striking bell rod are shaped like sword points, and the rod is supported so that it can freely slide left and right, and is also held lightly by the control piece 10 so that it does not move up and down, so that it is tilted. The striking bell rod 8 slides effortlessly every time the tip hits the striking protrusion, and therefore the tip of the striking bell rod suffers little wear due to impact, and also resists against rotation of the seat plate 3. Therefore, the seat plate rotates easily, and the striking action is almost as good as that of a conventional bell.

In the present invention, which is constructed and operates as described above, unlike the conventional metal pendulum, as mentioned above, the seat plate is molded from synthetic resin, and the striking bell rod is formed from a single rectangular small piece of iron, which is extremely simple. Because of its structure, the number of manufacturing steps is small and it is suitable for mass production.In particular, since the seat plate 3 is molded from synthetic resin, it has the advantage of not only being easy to manufacture, but also having a relatively low production cost. Due to these advantages, the present invention is convenient for mass production and has an economical effect that it can be produced at a lower cost than conventional bicycle bells.
