Abstract

An anti theft alarm for a bag attached to an existing carrying strap 8 comprises a first housing 5 and a second housing 6 held together by an elasticated band 10 (see figs 2 and 4). The first housing contains an alarm (buzzer), a power source and a reed switch. The second housing contains a magnet 7. The housings together form a hole 9 into which the strap 8 is folded (fig 3). When the bag is snatched the elasticated band 10 stretches and the first and second housings separate, causing the reed switch to open which in turn operates the alarm. In an alternate embodiment the strap does not pass through the housings, but each of the first and second housings is secured separately to a free end of the strap.

Description

( SNATCH ALARM

"Bag - snatching" and the criminal act of"snatching" or sudden removal by force of a persons 'bag' or container, of one kind or another by a passerby, or would be thief, is becoming an ever increasing crime in both 'town' and cities alike.

The bag or container will have straps of varying types and lengths, which are suitably attached to the bag; such that the bag can be carried either from the Shoulder' or 'hand'.

The invention by way of the following description and drawings, seeks to provide a

simple and effective way in obstructing the potential act of 'snatching' when the crime takes place. causing the thief to withdraw from the scene, or even be arrested.

According to the present invention an alarm device is fitted to the 'carrier strap', or fitted to the bag at the position or point where the strap is located and fixed.

The device is self contained and houses both the power source or 'cell'. an 'audible alann' or 'buzzer' and the necessary electronics to effectively activate the alarm', if the 'bag' attached to the strap is suddenly snatched tram the 'person' or 'victim'.

Fig I is a front elevation of the device, closed position Fig 2 is a end elevation Fig 3 is a sectional end elevation Fig 4 is a front elevation open position The following description describes using drawings, fig 1 2 and 3 the device in a

closed activated condition.

Item 5. Fig's I, 2 and 3 is the 'top' part of the device manufactured from the plastic or any material which satisfies the design criteria, housing both the alarm, 'power cell' and commercial type 'reed switch' (not shown).

-1

À All suitably connected by an electronic circuit to satisfy the various electrical requirements of the components.

Item 6 fig's 1, 2 and 3 is the 'lower' part of the device manufactured from a compatible material to that of the 'top' item 5.

Item 7 fig I is a commercial type magnet (shown by dotted line) compatible and capable through its magnet field to operate satisfactorily the 'reed switch'.

If for exernple item's 5 and 6, fig 1 and 2 are manufactured from say 'mild steel' or tin- plate' or any magnetic material.The magnet item 7 fig I and the 'reed switch' (not shown) would require mounting in a suitable 'non - magnetic' pocket in both the Top' and 'lower' parts. This will prevent amplitude or Luxation of the magnetic field.

which would impair the correct workings of the 'reed switch'.

Item 8 fig's 1 and 3 is the existing 'strap oil the respective 'bag. or 'container' to which the device will be fitted.

One free outer end of the 'strap' will require to be 'passed' through suitable slots' or openings' (not shown) within the 'top' and 'lower. part items 5 and 6 fig's 1. 2 and 3 such that the 'device' becomes an integral part of the strap 8.

Two location 'pins' or 'pegs' (not shown) will be required in either the 'lower' part 6 or the top' part 5 such that these can locate in corresponding compatible holes in the opposite part or section.

These 'pegs' will act as locating 'pins' to ensure that the contours of the outer surfaces of the 'top' and 'lower' parts are satisfactory aligned with each other.

1 he 'hole' item 9 fig's t and 3 allows the 'strap to told neatly inside.

Item 10 fig 2 is an elasticated 'band' or Cord' either that of a single filament or multi - strand. The pre- determined tension of the band 10, is an important factor of the design; and as such controls or retains the top item 5 and lower item 6, within the groove 11 fig 2.

(. In a set position relative to each other depicted by the dimension 'A' fig 4.

Within this position, the device is primed and activated as the reed switch' (not shown) is in its closed position; (once the 'reed switch' is in 'open' condition, then the 'alarm' will sound).

There is sufficient elasticity within the band item 10 to allow lull weight of the ibag' or item being carried such that varying movement 'upwards' and 'downwards' of the top part of the device shown by the arrow x' fig 4.

Once the act of 'snatching' the bag takes place, the elasticated band item 10 fig's 2 and 4; will cause the 'top' part item 5 to move rapidly away from the lower part item 6. Such that the magnetic field of reed switch (not shown) in its 'open' condition

therefore the 'alarm. will sound.

This condition will remain until the 'reed switch' is returned to closed.

A further embodiment of the invention is that the 'strap' item 8 fig's t and 3 does not go through slots' or 'openings' within the itop' and lower parts item 5 and 6 fig's 1 and 2; but alternatively is secured separately to the 'top' and 'lower' part, such that they are attached to two open ends of the strap 8 by a suitable means to satisfy the design criteria.

The two parts item 5 and 6 will have a suitable 'tongue' in one half and 'groove' in the other, and will then slot into each other, held in place by friction and a suitable pin of a specified diameter manufactured from 'plastic' or the like. This will break suddenly if the 'bag' is snatched.

Finally, if the device aforesaid described in the description, where a reed switch and

magnetic are used, then it will require some form of tell - tale notification to the user.

if tor example the device is not active due to 'low' power of the battery icell', or some fault in the electronic circuit.
