Abstract

A battery operated self contained vehicle alarm device which can be attached to a vehicle's steering wheel or similar structure and locked into position by a locking mechanism. This locking mechanism prevents the device from being dismantled whilst in the locked position. The unit contains one or more of various sensing devices to trigger the alarm.

Description

SELF CONTAINED LOCKING VEHICLE ALARM DESCRIPTION
Vehicle alarm devices are well known and exist in various forms and shapes.
However all of these devices suffer from one major disadvantage. They have to be installed by a competent person since they use the car's battery as a power source.
Although the devices are relatively cheap to manufacture, they are rather expensive for installation.
There is now described by way of example and with reference to the accompanying drawings an alarm device which is self *LQ contained and locks to the steering wheel or similar structure of a car or other vehicle. The invention entitled
"SELF CONTAINED LOCKING VEHICLE ALARM" consists of the following; i) a lock assembly (fig 4g) 15 ii) a hasp (fig 4h) iii) front and rear enclosure halves (fig 4m) iv) ON/OFF switch (fig 4i) v) self contained power source (fig 4d) vi) electronic circuitry (fig 4k) 20 vi'i) an audible alarm (fig 41) viii)a -visual alarm (fig 4j) ■ ix) sensing devices xi battery access casing (fig 4o) xii) locking screws (fig 4a, 4c, 4f) 25 The lock assembly is preferably a key operated lock, which when turned to the "ON" position causes a locking arm to engage in the hasp and also operate an "ON/OFF" switch arrangement. The hasp closes around the rin or spokes of the steering wheel and therefore secures the alarm device to the wheel. To prevent the hasp from being cut open by a thief, it is manufactured of flame hardened steel or of a similar material. The lock assembly and the hasp are arranged on opposing halves of the enclosure, which is also made of vandal resistant material such as, for example, polycarbonate. That prevents the device*from being removed or disabled, because the lock and hasp in the locked position also hold the two enclosure halves together so that they can not be disassembled in situ even if screws holding the two halves together were removed. Once activated by the owner, the electronics, when initally powered up, starts a delay to •enable the owner to leave the vicinity without causing an alarm situation. After the delay has lapsed the alarm device is fully armed and ready to detect an intruder or damage caused by forceful means. As soon as such a disturbance is detected, the device goes - into a further delay mode, which is necessary for the authorised user to turn off the device without causing an audible nuisance. A thief could not do so without the correct key and therefore, after this second delay has lapsed, an audible and/or visual alarm is activated. Turning the lock assembly to the "OFF" position deactivates the alarm and also disengages the hasp so that the device can be removed from the steering wheel. An intrusion or forceful damage can be detected by either ultrasonic movement detection, passive infrared movement detection (body heat), mercury tilt switch, mechanical or piezo electronic vibration sensors. The unit can house a combination of those methods or can cater for one of the above menthods only. The power sourse consists of batteries which can be throwaway type or the rechargeable type. A facility for connection to the vehicles power supply is preferably catered for but is not essential. If this is provided, the self contained power source can be of the recahrgeable type and used as a secondary backup. Also such connection facility is polarity protected and the power derived from such connection is electronically regulated. Furthermore such connection to the vehicle's power supply allows detection of opening doors for example by detecting the momentary voltage drop caused by the internal car lights coming on.
