Abstract

The present invention relates to improvements in earthquake alarm apparatus (alarm) comprising, in a technical technical combination, a lower box-like mounting base with a side cover, a switch, and an upper surface with a ring Copper located in the center of the surface, held by means of lugs, this base is fixed by means of fasteners to a wall or other element selected so that it has no movement, the base also includes an electric bell, a focus and an electric dry battery to activate the bell and / or turn on the focus when closing the circuit of the alarm device, mounted on the base is a clear acrylic cylinder that encloses a plumb-shaped plumb and conductive electrical material, suspended by a thread, the transparent cylinder carries a top cover, under the movement, the plumb line making contact with the ring triggers the bell and / or lights the focus, characterized the improvements It is included in the top cover of the transparent cylinder a graduation screw, which on the inside is attached to the pendulum thread and which protrudes from the outside to make it rotate and be able to adjust the sensitivity of the device, and because on the upper surface of the base lower mounting, where the conductor ring is included a spring system composed of spring-loaded adjustment screws in the four corners of the upper surface, which allow to level the conductive copper ring, allowing the conical plummet always to be well centered in the A

Description

IMPROVEMENTS IN SISM ALARM APPARATUS D E S C R I P C I O N The present invention is related to an alarm (earthquake alarm), that is to say sudden movements, shaking or succession of vibrations of the ground. Different devices are already known to detect earth movements, earthquakes, etc. They include sophisticated electronic technology and are generally available to institutes or research sites, such as observatories, detection centers, etc. These devices are not available to people both in their price and in the use of their technology. The inventor of the present has proposed the design of an earthquake alarm clock, practical, safe and economical that anyone can buy, assemble and therefore have at home or in his office with the consequent advantage of being able to detect immediately the beginning of a movement of the earth. The seconds that can be gained in detecting the start of an earthquake are decisive and can save many lives.

THE INVENTION The present invention is directed to the detection of earthquakes by means of an alarm device (alarm) of earthquakes consisting basically of an electrical circuit with a sound element, for example a bell, which will be operated through a copper plumb line that closes the circuit to the movement of the earth. From this idea of a plumb line that when moving closes an electrical circuit that triggers an alarm, different embodiments can be made within the field of the invention, which should be considered in its broadest and non-limiting sense. Next, a detailed description of a preferred but not unique embodiment of the invention will be made, with reference to the attached schematic drawing. The single figure shows an earthquake alarm device in an exploded form, that is, with the parts raised for better appreciation; the description will be made from top to bottom. The earthquake alarm of the present invention comprises a cover 1 leading towards the center an adjusting screw 2 holding a pendulum 3; the adjusting screw 2 serves to adjust the pendulum 3. The pendulum is preferably in the shape of a cone and is made of an electrically conductive material, for example copper. The pendulum 3 is supplemented by a wire 4 fastened to the screw 2; also the connectors 5 are located in the upper part and in the lower part in another plate there are fasteners 6 for fastening the pendulum assembly to the base. The above is enclosed within a transparent cylinder 7 for example of acrylic. The pendulum assembly 3 is mounted on top of the base 8 by means of the fasteners 6; the base has a system of springs (not illustrated) to balance the pendulum and reach an exact plumb point of the pendulum 3. The pendulum 3 is inserted into the space of a copper ring 9 which will be the positive pole of an electric circuit . At least one corner of the base 8 is another adjusting screw 10 and finally inside the base is the electric bell 11 which will be driven to the movement of the pendulum 3 inside the copper ring 9. The electrical circuit can be driven by a battery 12 for example a 6 volt battery that lights a bulb 13 to indicate that the earthquake alarm is connected; the bulb may have an amber-colored mica 14 and the apparatus may carry lugs 15 for attachment to a wall.

Also illustrated is the connector 16 of the apparatus to the battery, the base cap 17 and a level indicator 18, in addition to the on / off switch. In the manner described above, an apparatus for earthquake, earthquake or similar detection is provided that is very economical in its manufacture and that therefore any person with a minimum expenditure can buy it and, consequently, install it, for example in his bedroom so that he awakens it in the moment when an earthquake begins to occur and you can do some maneuver that can eventually save your life. All the basic elements have been described and their simple connection is such that by touching the positive copper ring the pendulum closes a circuit that triggers the bell or any similar sound device. Although a timbre has been mentioned, the circuit that closes with this device can be connected to any other element of sound or illumination (in case of deaf) all this according to want.
