Description

ANTI-HAZARD DEVICES This invention relates to an anti-hazard device for responding to a detected hazard by emitting an anti-hazard substance. The device may be one that can be installed at various locations to automatically spray irritative gas activated by a sensor coupled to an electronic control main unit in case of an attack, robbery or burglary to supress villains. The device may include a closed-circuit monitor, illumination equipment, an alarm and such components as a solenoid sensor, vibration sensor, etc. to compose an integrated safety system, so as in case of an emergency, simultaneously to give alarm and switch on the illumination equipment and take the photo of the villain from the closed-circuit monitor to facilitate identification of the villain.

Robbery and burglary have long history in human life. In these days of highly advanced science and technology and upgraded living standards, however, robbery and burglary are not on the decline. Villains are nowadays using more dangerous weapons than before.

When the police arrive at the scene of a robbery case, the villains often have gone away leaving no trace behind. Therefore, it is imperative to develop a more effective protection device to ensure the safety of human life and property. In view of the above, the inventor has actively studied ways to solve such problems, and has come up with a type of automatic anti-intruder device which will be able to protect human life and reduce financial loss, variants of which may be used for combatting other hazards.

The present invention provides an anti-intruder device comprising an intrusiqn detector coupled to apparatus for emitting an anti-intruder substance in response to activation of said detector by an intruder, said apparatus comprising a pressurised reservoir of said substance, an outlet valve for emitting said substance from said reservoir, and means responsive to said detector for activating said outlet valve to emit said substance.

Said outlet valve is preferably operable by movement of said reservoir relative to a support member for said outlet valve and said responsive means acts to so move said reservoir in response to said detector.

In use said reservoir is preferably moved toward said support member against which bears an operating member of said outlet valve to open said outlet valve.

Said responsive means preferably comprises a solenoid acting directly or indirectly against said reservoir.

The device may have a base having thereon a slideway upon which is received said reservoir.

The slideway is preferably of generally V-cross section.

The reservoir is preferably a cylinder.

The anti-intruder substance may be a gas.

Said outlet valve may have a spray outlet nozzle.

The device may further comprise control apparatus coupling said detector to said responsive means.

Said control apparatus may have outputs to one or more of a visual alarm, an audible alarm, a camera, means for telephone dialling or otherwise transmitting an alarm signal to a remote location and means for activating lights.

Said control apparatus may have an input from one or more of a smoke detector and a fire detector coupled to said outputs.

Said intrusion detector may be a closed-circuit TV system, a vibration sensor, an infra-red sensor, an optical or electric continuity sensor or a pressure sensor.

The invention includes an automatic anti-hazard device comprising a hazard detector, a housing containing a slideway mounting a cylinder of pressurised anti-hazard substance, said cylinder having an outlet valve of the push operated type abutting an outlet nozzle provided in said housing, a solenoid mounted in said housing and connected to move said cylinder along said slideway toward said nozzle to open said outlet valve when activated, and control means coupling said detector to activate said solenoid when a hazard is detected.

Said housing may contain a support member spanning between opposed sides of the housing over said cylinder and slideway, upon which mounting member is mounted said solenoid.

Said device may further comprise a mounting device including a mounting stalk connected by a ball and socket adjustable connector to said housing and having at its other end a fixing plate by which to mount the device.

Said anti-hazard substance may be a fire extinguishing composition.

The device may be mainly composed of a gas cylinder, solenoid, sliding seat, spray nozzle, base, casing, adjustment seat, fixing rod, etc. to form an automatic gas spray device which is installed in a particular place at one's house or other location. NZhen the robber activates the sensor, the pushing rod at the centre of the solenoid pushes the gas cylinder in the sliding seat. Gas is sprayed from the nozzle to stop the robber. Meanwhile, it activates the alarm, lighting fixture and closed-circuit monitor, as well as an automatic call to nearby a police force or relatives or friends. This invention, when used at ones house and other facilities or locations protect human life and property against robbers.

The device may be a type of "automatic gas spray device and its safety system", particularly one that can be installed at a particular location or one's house to spray gas at the robber or burglar and meanwhile to give alarm sound and switch on illumination equipment and closed-circuit monitor and to automatically notify nearby policy force or relative or friends, to achieve the purpose of arresting the villains.

The invention will be further described by way of example by the following detailed description of a preferred embodiment, as illustrated in the following drawings, in which: Figure 1 is a perspective view of an embodiment of the invention; Figure 2 is a sectional view of the device of Figure 1; and Figure 3 is a flowchart of the safety system of the device of Figure 1.

The drawings show a type of "automatic gas spray device and its safety system", to provide a safety measure to various locations or residences, to quickly spray gas to stop a robber (burglar), and meanwhile to activate an alarm and illumination equipment to facilitate a closed-circuit monitor taking photos of the robber (burglar) to enable an earlier arrest. By means of the automatic gas spray device and described electronic control main unit automatic call to the police, alarm, illumination equipment, closed-circuit monitor and other components such as solenoid sensor, vibration sensor, infra-red detector, smoke detector, etc. to form a protective safety system against robbery, burglary and fire accident, to ensure human life and property safety, and to speedily arrest the robber (burglar).

Referring to Figure 1 and Figure 2 which are perspective and sectional views of an embodiment of the invention, in a base 1 is a "v" sliding seat 12 (or slideway of v-cross section) in which is a gas cylinder 2. A push tube 21 at the front of the gas cylinder 2 is fitted with a spray nozzle 22. At an appropriate location of the base 1 is a "n" shaped fixing seat 13 on which is a solenoid 4 for acting through a central push rod 41. One end of the central push rod 41 is in touch with the rear end of gas. cylinder 2. When the sensor transmit signals via the electronic control main unit to activate the solenoid 4, then the central push rod 41 will push the gas cylinder 2, and gas will be sprayed from the nozzle 22. The base 1 is covered with a casing 3 fixed by several screws 14. On top of the casing is a ball-shaped adjustor head seat 51 connected from inside with the ball head and the other end fitted with the rack 5 of fixing plate 52, fixed in position by screws 52'.
