Abstract

A portable security apparatus of the type adapted to be activated in the event of an article being removed from a particular vicinity is maintained in an inoperative condition by electromagnetic radiation of a predetermined character emitted by a separate transmitter. The apparatus is activated by moving the transmitter and switching arrangement apart by more than a predetermined distance. Preferably a key operated switch is incorporated in the switching arrangement, a key being required to switch the alarm off after activation. The preferred embodiment has the security device incorporated in a briefcase or like portable container. <IMAGE>

Description

SPECIFICATION Portable security alarm This invention relates to a portable security alarm of a type designed to be activated in the event of an article or other suitable movable object being removed from any particular vicinity and, more particularly although not exclusively, a handbag, briefcase or other portable container such as a container used for transporting money.
Numerous different proposals have been made for automatically activating alarms in the event of an article being removed from a person or place by unauthorised persons. Many of these rely on the physical attachment of a part of a device to the person such that an alarm or other security apparatus is activated when this part is detached from the briefcase, bag or other container. Generally an authorised person has a key or other means for disabling the security apparatus.
Such arrangements are not generally satisfactory as it requires a positive physical act in order to ensure that the security apparatus is operative and could thus lead to a tendency for it not to be used.
It is the object of this invention to provide a security alarm or other similar apparatus in which physical attachment of a part to a person is not required.
In accordance with this invention there is provided security apparatus comprising an alarm or other security device adapted to be activated by a switching arrangement and wherein the switching arrangement is adapted to be maintained in an inoperative condition by electromagnetic radiation of a predetermined character emitted by a separate transmitter adapted to be located in the vicinity of the switching arrangement, the arrangement being such that when the switching arrangement is moved beyond a certain distance from the transmitter, the security apparatus is activated by the switching arrangement.
Further features of the invention provide for the security apparatus to be a battery powered alarm; for the transmitter to be a battery powered radio transmitter having a short range, selected according to the requirements of separation between the transmitter and switching arrangement for activation of the security apparatus. for the security apparatus and switching arrangement to be built into a briefcase or other portable container such as a bag, suitcase or the like; and for a key operated switch to be included in the switching circuit such that a key is requird to switch the security apparatus off after activation. The same key could be employed to switch the entire apparatus off so that it is not activated at all.The security apparatus may obviously be utilised with virtually any movable object and its inclusion as a security device for a motor vehicle is specifically envisaged.
In order that the invention may be more fully understood, one embodiment thereof will now be described with reference to the accompanying drawings in which: Figure 1 illustrates a briefcase embodying a security alarm according to this invention, and, Figure 2 is a block diagram of the circuit of the security alarm.
In this embodiment of the invention a security alarm unit 1 is built into a briefcase 2 such as in one corner thereof, for example. The unit is adapted to be powered by a battery 13 and embodies a switching arrangement 4, a key operated switch 5, a siren 6 and a radio receiver 7.
The arrangement of the above components is such that when radio waves are received by the receiver and these conform to a pre-set character, the switching arrangement is held in an open condition and the siren is isolated from the battery. This is achieved by means of a radio transmitter unit 8 which is also battery powered. The switching arrangement may comprise any one of a variety of switching devices which will be obvious to one skilled in the art. These switching devices may be electromagnetic, may be diode controlled or may comprise any other switching device which when sensing a diminishing signal will cause the alarm to be activated.
The range of the radio transmitter is such that when the transmitter and briefcase are separated by more than a predetermined distance, which could be as short as one metre, the switching arrangement will change condition and cause the siren to be activated by the battery. Once activated, the key operated switch must be employed to disconnect the battery from the siren.
The same switch can be operated, for example, by rotating it in an opposite direction to disable the entire unit during periods of non-use.
Numerous variations may be made to the above described embodiment of the invention without departing from the scope hereof. For example, the siren could be replaced by other security devices which may have any effect and may be adapted to spray dyes or emit tear gas or the like. The security apparatus may be mounted to a motor vehicle, such that if the motor vehicle is moved beyond a predetermined distance from the transmitter, which may in this instance be mains powered, will be activated.
It will be understood that virtually any suitable movable object may have a security apparatus as described affixed thereto and be adapted to activate an alarm if moved more than a predetermined distance away from the other component of the security apparatus. It will also be understood that either the alarm or the transmitter may be mounted to the object which is adapted to be stolen or moved away.
It is envisaged that the invention will provide a useful and effective security apparatus which does not require the physical attachment of a container, bag or the like or a part thereof to a person in charge of same.
