[0001] The present invention refers to an anti-theft prevention device that provides an
alarm and is thereby adapted to signal a current attempt of theft or bag-theft.
[0002] The ability of a bag-thief is such as to make practically impossible to be aware
of the stealing action in course, so that it is impossible to prevent it and therefore,
almost in all cases, the affected person is made aware of the occurred event only
afterwards, without being able to do anything to intervene and/or locate the responsible
therefor.
[0003] The general object of the present invention is providing a prevention device that
is capable of perceiving the bag-stealing event currently being done with an acoustic
signal that, in addition to warn the affected person about what is happening, discourages
the responsible thieve from going on performing his action.
[0004] The above and other objects and advantages of the invention, as will appear from
the following description, are obtained by an anti-theft device as claimed in Claim
1. Preferred embodiments and non-trivial variations of the present invention are claimed
in the dependent Claims.
[0005] The present invention will be better described by some preferred embodiments thereof,
given as a non-limiting example, with reference to the enclosed drawings, in which
the only Figure 1 is a schematic view of a possible practical embodiment of the device
according to the present invention.
[0006] With reference to Fig. 1, a practical embodiment of the present invention is shown
as a non-limiting example, In fact, the inventive device described hereinbelow is
obviously adapted to be applied to any pair of transmitting-receiving elements, located
into any object that can be placed into a bag, a pocket or another container, or realised
in order to be able to be itself connected to bags, pockets, etc.
[0007] The device of the invention is substantially composed of two different elements 1,
3 with small sizes, mutually interacting by means of electromagnetic waves and/or
low frequency radio waves, of which one element 1 (or 3) is of the emitting type while
the other element 3 (or 1) is of the receiving type.
[0008] In particular, it is provided that the emitting element 1 is of small sizes, like
a pocket gadget, with an emission range limited to 1.5 meters, and is able to be placed
into a pocket or a bag or another place adapted for its purpose. In the embodiment
shown, the emitting element 1 is placed into a pen, or is realised in order to look
like a pen from the outside, however equipped with the typical functions assigned
to such emitting element 1.
[0009] The receiving element 3 is also of small sizes: in the example shown in Fig. 1, it
is realised as a credit card with a minimum thickness, able to be placed into a wallet
or another suitable place.
[0010] The emitting element 1, that can be activated by the user when it is necessary, interact
with the receiving element 3 at a preset distance varying between 0.2 and 1.5 meters
max.
[0011] When the two elements 1, 3 are moved away, they activate an immediate acoustic signal
(by means of suitable sound means, not shown) both in the emitting element 1, and
in the receiving element 3, realising the object of the present invention.
[0012] The max operating distance is purely an indication, since the chosen range is the
one currently deemed as optimum, but the choice is obviously not limiting.
[0013] The two elements 1, 3 are finally supplied each by its own battery (not shown) and
can be customised with a coupling code, so that they cannot be deactivated by a foreign
emitting source.
[0014] Some preferred embodiments of the present invention has been previously shown and
described: obviously, numerous variations and modifications, functionally equivalent
to the previous ones, will immediately appear to the skilled people in the art, such
variations and modifications falling within the scope of the invention as pointed
out in the enclosed Claims. For example, as already stated, the two elements 1, 3
can be realised in the described shape or in any other shape.
[0015] Moreover, it is possible to invert the position and function of the two elements
1, 3, so that, opposite to the example shown in Fig. 1, the emitting element 1 is
the credit card and the receiving element 3 is the pen.
[0016] Moreover still, the emitting or receiving elements 1 or 3 could be placed into precious
objects, such as bracelets, necklaces or other ornamental objects, in order to prevent
their theft too.
