The bicycle bell includes a bell body, a thumb-operated clapper or lever adapted to strike the bell body in order to produce a sound, a frame element holding the bell body and the thumb-operated clapper or lever, and a mounting mechanism carrying the frame element. The mounting mechanism includes a mounting shoe having at least one abutment surface adapted to abut a flat surface of an object and a permanent magnet arranged in the mounting shoe, and the at least one abutment surface of the mounting shoe spans at least a distance corresponding to a third of a largest dimension of the bell body.

A mechanical warning device (1) for a vehicle, including for a velocipede, includes a body (2), a ringer (3) mounted on the body, a striker (4) movably mounted on the body and relative to the ringer, and a magnet mechanism (5) which is configured such that, when the striker is displaced from a stable position to an intermediate position in which it has been displaced away from the ringer, it drives the striker from the intermediate position to strike the ringer then brings the striker back into the stable position.

A pet-activated signaling device, a pet-activated signaling system, and a method of a pet signaling a human is provided. The pet-activated signaling device includes a belt, a transducer, and multiple bells. The transducer, which emits an electromagnetic signal, and bells, which emit an audible signal, are attached to the belt. The pet-activated signaling system includes the signaling device and a receiving device which emits an alert when a signal is received from the signaling device. The method of a pet signaling a human includes pawing at the pet-activated signaling device suspended from a door handle to activate the transducer and the bells. The invention is particularly useful for use on an exterior door, allowing a dog to use a familiar method of alerting a human to open the door even if the bells are not heard by the human.

The present invention relates to an acoustic signaling device for generating an acoustic signal is provided, which comprises an oscillating body for generating the acoustic signal in an oscillating state, an excitation means for manual excitation of an oscillation of the oscillating body, and a holding means for holding the oscillating body and for bearing the excitation means, wherein the oscillating body comprises an opening through which the actuation element is guided, in order to bring about a strike of the excitation means on the oscillating body upon actuation of the actuation element. The acoustic signaling device is characterized by a cover, which consists of a resilient material and covers the oscillating body on a side opposite the excitation means, preferably completely.

A sound generation angular velocity-adjustable twirling device detachably attaches to a fabric-article at a peripheral attachment point or a central attachment point and enables rotation of fabric-article. The fabric-article unfurls and twirls at a rate dependent on the center of gravity at different attachment points on fabric-article. A rod forms the central axis. A textured outer sleeve encapsulates the rod for secure grasping. A first axis positions in the outer sleeve, fixedly attaching to a first-rod end. A fastening mechanism rotates freely about the first axis while retaining the fabric-article. The rotating fastening mechanism and the stationary first axis form a rotational relationship with low friction coefficient. A second axis pins a strap to the second-rod end. The device generates sound while twirling through a gear assembly and/or percussion instruments. The sound generated is proportional to the angular velocity of the gear, and to the applied torque to the sleeve.
