DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The following descriptions are of exemplary embodiments only, and are not intended to limited the scope, applicability or configuration of the invention in any way. Rather, the following description provides a convenient illustration for implementing exemplary embodiments of the invention. Various changes to the described embodiments may be made in the function and arrangement of the elements described without departing from the scope of the invention as set forth in the appended claims.
Referring to FIGS. 2 to 4, there is shown a magnetic lock comprising a magnetic lock body 1, and a metallic plate 2. The metallic plate 2 is mounted at the lateral edge of a door panel 31 and the metallic lock body 1 is mounted to the inner edge of a door frame 3 by means of a securing plate 11, corresponding to the metallic plate 2. When the door panel 31 is closed, an electric current passes through to generate a magnetic force so that the metallic plate 2 is attracted to form a locked door with the door panel 31. One end of the lock body 1 is a control section 12 mounted internally with a frequency sensing device and at least a video lense 13. The frequency sensing device receives the external frequency control signal to control the lock body 1 from engaging with the door panel 31. The video lense 13 monitors the surroundings of the door frame 3 and the passage path when door panel 31 is opened so as to ensure the door is closed and to provide video function.
FIG. 5 is another preferred embodiment in accordance with the present invention. The magnetic lock 10 is installed onto a door structure. In this preferred embodiment, the video lense 13 is omitted and only the frequency sensing device is installed such that the magnetic lock provides only the function of a lock and the controlling of the lock.
In accordance with the present invention, the video lenses can be either installed at the front edge or the read edge of the lock body.
It will be understood that each of the elements described above, or two or more together may also find a useful application in other types of methods differing from the type described above.
While certain novel features of this invention have been shown and described and are pointed out in the annexed claim, it is not intended to be limited to the details above, since it will be understood that various omissions, modifications, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing in any way from the spirit of the present invention.
