[0001] The present invention relates to a method of security and an antitheft device for
flat panel computer monitor.
Background of the invention
[0002] Flat panel monitors are becoming increasingly more common year by year. They are
popular and are frequently used in connection with various types of terminals. The
monitors function more or less in the same way as monitors on notebook computers.
Using Liquid Crystal Display (LCD) technology it is possible to control how much light
will be allowed to pass through a point. These small points in a monitor screen enable
information to be displayed on these monitors. Each point consists of three small
crystals each of a different colour (red, green, blue), each separately controlled
by its own transistor.
[0003] The flat panel monitors draw less power and also emit little radiation. A further
advantage of these monitors is that they take up less space compared to conventional
monitors.
[0004] On the other hand, flat panel monitors will continue to be more expensive than conventional
monitors.
[0005] The advantages of the flat panel monitors and the fact that they are relatively expensive
have meant that they are an attractive target for thieves. They are easy to carry
since they are relatively small and light. On public and other terminals equipped
with flat panel monitors the theft of monitors is frequently a problem.
[0006] The object of the present invention is to specify a method and a device for reducing
the number of thefts of flat panel monitors.
[0007] There are at present a few solutions available for securing monitors, but these involve
the fitting of various large fixing plates, securing blocks, locking sleeves and other
more or less awkward devices for securing the monitors. Access to the chassis of the
monitor is often required in order to secure the monitor firmly to its work station.
[0008] The method and device according to the present invention are intended to secure a
flat panel monitor in place without the need, among other things, for awkward intervention
in its construction and without the need to open up the chassis of the monitor.
[0009] The present invention relates to a method according to claim 1 and a device according
to claim 4 for performing the method according to the invention.
Summary of the invention
[0010] The device according to the present invention comprises two cables, and a locking
eye with a threaded pin for fixing to the display monitor.
[0011] One cable has a stop at one end, and at its other end a locking device which allows
the one cable to be locked to the other cable. The two cables are intended to be locked
together by a method known in the art.
[0012] At one end the second cable comprises a locking device which allows the second cable
to be locked to the first cable. An eye is formed at the other end of the second cable.
[0013] By means of the cables and the locking eyes a flat panel monitor is securely locked
to a work station.

Detailed description of the invention
[0015] Characteristic features and advantages of the invention will now be described with
reference to an embodiment, shown by way of a non-restrictive example in the drawings
attached.
[0016] The device according to the present invention comprises two cables 1, 2, a locking
eye 3 having a threaded pin 4 for fixing to the monitor 8.
[0017] At one end, the cable 1 has a stop 5, and at its other end 6 a locking device which
allows the cable 1 to be locked to the cable 2. The two cables 1 and 2 are intended
to be locked together by a method known in the art.
[0018] At one end the cable 2 comprises a locking device 7 which allows the cable 2 to be
locked to the cable 1. An eye 9 is formed at the other end of the cable 2.
[0019] At least two but preferably four locking eyes 3 are used. The requirements for the
locking eye 3 are that it should have a through-hole in it and a facility for screwing
the eye 3 firmly on to the back of a monitor 8. The embodiment of the locking eye
3 may vary considerably without departing from the idea of the invention with regard
to this. The eye 3 is preferably made of steel. The great majority of flat panel monitors
have four tapped holes on their rear side that are made during the manufacturing process.
[0020] When, for example, a flat panel monitor is to be secured in a chosen location, at
least two and most preferably four eyes 3 are screwed into tapped holes or on to threaded
pins on the back of the flat panel monitor 8. The cable 1 is then inserted through
all the eyes 3, which are thereby secured to the flat panel monitor 8.
[0021] The second cable 2 is now secured to a fixed location on the work station, for example
by threading the cable round the fixed location and through the cable's own eye 9.
The cable 2 is preferably appreciably longer than the first cable 1. The locking device
7 of the cable 2 is then secured to the locking device at the end 6 of the cable 1.
When the cable 1 is inserted through the locking eyes 3 and these are secured to the
flat panel monitor 8 it is no longer possible to unscrew the locking eyes 3 which
have just been screwed in place. The cable 1 prevents the eyes 3 from being unscrewed
from their firmly screwed-in position on the back of the monitor 8, with the result
that the flat panel monitor is firmly secured to its work station.
[0022] The cables 1, 2 preferably comprise a number of thin steel wires enclosed by a plastic
sheathing. Forcing a locking cable of this type in the absence of a key requires special
tools and cutting the cable, for example, is at all events time-consuming. The device
according to the invention therefore affords good protection against theft when secured
in the manner described above.
[0023] The embodiment may be modified in various ways, for example in the cable material,
type of lock and in other respects, without departing from the idea of the invention.
[0024] It is also possible to use just one longer cable, which is inserted through the eyes
and firmly secured to a fixed location by some device.
[0025] It is also possible, instead of using a short cable with a stop at one end, to use
a cable with locks at both ends, which is then secured to a longer locking cable.
[0026] The number of eyes used may also vary from one to several eyes. There need not necessarily
be four eyes.
