Electrically propelled display device with simulated hovering and/or flying patterns

Abstract

The present invention is referred to an electrically propelled display device with simulated hovering and / or flying patterns, comprising a driving unit; said driving unit includes a base, a central hollow body and a rotatable head. A power source is connected to the driving unit, a flexible support is attached to the rotatable head of the driving unit and a display pattern is attached to the flexible support. Said driving unit includes in the central hollow body an oscillator electronic circuit and an electric motor. Said oscillator electronic circuit is connected to the power source and to the electric motor which includes a driving motor shaft attached to the rotatable head. This device simulates the movement of some flying objects and aliforms, such as birds, bats, butterflies, dragonflies, fairies, or the like. The oscillator circuit sends pulses at a certain frequency to the motor, generating an intermittent, rotational movement. This movement is transferred to the wire, which, then accentuates and transmits this movement to the object. The ultimate effect is the combination of a rotational movement, and a movement that simulates the flapping of wings of some flying animals and fairies, or the movement of other aquatic or terrestrial animals. The speed and intensity of rotation and flapping change with the frequency and pulse width of the wave that the oscillator sends. The device may be used in decorative, educational, promotional, and entertainment applications. It may be used both, indoors and outdoors.

AI Technical Summary

Benefits of technology

[0013]The general purpose of this present invention is to provide a very economical and easy to use product, that may be used in decorative, promotional, educational, and entertainment applications, and that succeeds in closely imitating the natural movement of aliforms, such as a butterfly, a dragonfly, a bird, a bat or a fairy. Just as an example, a butterfly pattern, with the aspect and movement of a real butterfly, may be very attractive for decorating a garden, the windows of a local shop, or simply a home.

[0016]Yet another aspect of the purposed invention comprises an electronic circuit known as an oscillator connected to the motor. This circuit is responsible for generating a squared wave with a graduated frequency and pulse width according to the speed and intensity of the flapping movement that is desired for the flying object. Each pulse activates the motor for a time that lasts as long as the pulse. A series of short, consecutive pulses causes a series of short activations of the motor. When the wave frequency is higher, the pulses have a shorter duration, and, thus, the duration of activations of the motor is shorter. Visually, an effect similar to a vibration is produced. The variation of the relationship between the motor activating and shutting off from the wave may produce various oscillation effects in the motor shaft, such as, alterations in the rotational speed, or changes in the intensity of the object's flapping movement.

Problems solved by technology

But this hovering effect cannot be maintained for a long time, and it is just an effect that lasts few minutes.

However, the angular movement in this device is an irregular movement caused by the loose connections and the type of flippable holding member to which a steel spring is attached.

However, a predetermined mechanical load imposed on the permanent magnet rotor effected by random striking of the simulated butterfly against the plant, or by random horizontal and vertical excursions of the simulated butterfly in its orbital path, or by random “hand-up” of the permanent magnet rotor on its shaft, causes the rotor to periodically and frequently reverse its direction of rotation.
