ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a magnet-sensible triggering doorbell mechanism, and more particularly to a doorbell mechanism which is provided with a magnet-sensible device so as to function more efficiently and can be provided with a pulling piece extended from the triggering doorknocker convenient for a short person or a kid to use.
2. Description of the Related Art
In the societies of multi-storied buildings, apartment houses are more and more.

Furthermore, the push-button device of the conventional doorbells is easy to be ill contracting when being operated.
SUMMARY OF THE INVENTION
Accordingly, the present invention is directed to a magnet-sensible triggering doorbell mechanism that can substantially obviate the drawbacks and promote the practical use of conventional related doorbells.
An object of the present invention is to provide a doorbell mechanism that is provided with a magnet-sensible device so as to function more efficiently and to avoid from ill contacting.
Another object of the present invention is to provide a doorbell mechanism that is provided with a traditional style of decorative doorknocker not only to catch the reactive trend but also to let the doorbell mechanism look artistic.
Yet another object of the present invention is to provide a doorbell mechanism that can be provided with a pulling piece extended from the triggering doorknocker convenient for a short person or a kid to use without trouble.
To achieve these advantages, a doorbell mechanism in the present invention includes a triggering board and a main body of a conventional doorbell. The triggering board has a magnet-sensible device and a decorative doorknocker. The magnet-sensible device and the decorative doorknocker are respectively provided with a magnet, and the doorbell can be switched on or off by means of the interaction of the magnetic fields of the magnet-sensible device and the decorative doorknocker. The decorative doorknocker can be provided with an elongate pulling piece convenient for a short person or a kid to use.
