"Bicycle bell with an operating lever carried by the housing base"

The innovation relates to a bicycle bell with a housing base that can be covered by a screw cap a tone generator rotatable about a central shaft and a with this in toothed engagement, provided with a return spring actuating lever with a handle.

Previously, the operating levers were made of metal; its return spring is e ^ 'ne locked at the bottom of the case Steel coil spring.

Jer Neuerur.E is based on the task of creating a simplified To create operating lever. In the case of a bicycle bell of the type mentioned at the beginning, the object is achieved by that the dpr operating lever is integral with its handle is made of plastic.

A preferred embodiment of the innovation is that on the actuating lever a supporting on the housing wall, trained as a return spring web or the like. is provided. The support could also be on one done in the case bottom pin or on a nose or a recess in the case bottom.

The operating lever can, as is known per se, to an in be rotatable near the passage opening in the housing base for its handle provided shaft.

Another variation of the new reune is that the actuating lever is designed like a ring and the inner edges of the ring as limiting surfaces for the movement of the operating lever are formed.

Furthermore, it is useful that the web or the like. with the Operating lever is connected at a point opposite the handle; the web can also be crescent-shaped being.

In the drawing, for example, embodiments of the innovation are shown. Show it:

A bicycle bell consisting of a housing base 1 and a screw cap 2 is to be used with a pipe clamp 3 Attach to the handlebar of a bicycle.

In the center of the housing bottom a shaft i ¹ I is mounted, which carries a rotatable around this shaft sounder. A gear 6 is provided on the underside of the frame for the tone generator.

In the vicinity of a passage opening 7 in the housing base for a handle 8 of the actuating lever 9, its shaft 10 is attached to the housing bottom. The wave has one pin-shaped extension 11 on which the one-piece operating lever 9 made of plastic

with its handle e.g. manufactured in an injection molding process. The operating lever is ring-shaped, so that its tooth inner surfaces 12 are in engagement with the gear 6 of the tone generator 5.

The ring-like design of the actuating lever is made in this embodiment so that a segment-like opening arises.

The inner surface 13 and the corresponding invisible opposite inner surface serve as stop surfaces for moving the operating lever in one direction or the other.

When the handle 9 is pressed in the direction of the arrow 20

if the operating lever is hidden around the pin 10,

is bound, approximately at a point that is opposite the handle 8. The sickle-shaped web 21 is supported on the approximately vertical wall 22 of the housing bottom and serves as a return spring, so that after a Letting go of the handle 8 in Pig. 2 position shown can be assumed again. When the Handle moves the tip 23 of the web along the wall 22 in the direction of the passage opening 7. Due to the inherent rigidity and elasticity of the plastic the return spring effect is achieved.

In the so-called trill bell shown in FIGS. 3 and 4 the central shaft 31 is fastened in the housing base 30. The actuating lever 32 with its handle 33 is similar to that of the embodiments according to FIG. 1 and 2 formed.

The shaft 31 carries the tone generator 3 ¹ I, which is provided with a gear 35. This gear 35 meshes with a gear part 36 of a wheel which is rotatably mounted on a shaft 37. The lower portion 38 of this wheel is designed as a small gear, which in turn meshes with teeth 39 on the actuating lever.

The web 40 is attached to one side of the actuating lever or is connected to it in one piece. The operating lever is rotated about its axis 42 in the direction of arrow 41 when the handle 33 is pressed, the tip 43 of the web 40 on the inner wall 44 of the housing bottom lengthways slides. The effect of the web is the same as that described in connection with the above embodiments.

The operating lever 32 has a modified ring shape
