[0001] This utility model regards a device which, placed in front of lock keyholes, allows
them to be protected against interference by unauthorised persons.
[0002] In particular this device comprises a high-resistance protection improvement which,
for locks of every type, is aimed at preventing violent attack on their keyholes,
and an improvement consisting of a base which allows for the insertion of further
lock protection devices of the same kind.
[0003] The utility model constitutes an innovation in the field of lock protection systems,
in particular those used for doors. Later, reference will be made to use of the utility
model for door locks. Clearly this is done solely for example purposes as the same
principles are valid for other applications for example, safes and locking systems
of the same kind.
[0004] At their current development level, devices used for lock protection and in particular
for the protection of their keyholes, are made of steel blocks and are not easily
perforated with a drill, but are unable to act as a base for the insertion and support
of further devices. In addition these devices are almost exclusively dedicated to
use for European cylinder locks and not for other types of locks for example, amongst
others, double map locks.
[0005] In reality this type of approach does not resolve the problem, because the lock's
aperture remains exposed and at the mercy of all.
Furthermore it is not taken into consideration that, in such a manner, in the eventuality
of an attempted break in the forcing of such devices results in then being damaged.
[0006] The utility model developed upon the system described above in that it almost completely
protects the lock's keyhole, rendering it impenetrable to attack by drilling tools
and at the same time, lends itself towards acting as a base for the insertion of further
total-cover keyhole protection systems, subject of other patents. Furthermore, being
made of metal and in any case being vary resistant, the device is impenetrable to
external attack by means of any type of tool or equipment.
[0007] This, the specific subject of interest of this utility model is a device for the
protection of lock's keyholes consisting of:
[0008] A base component with a hole through which access to the lock is possible.
[0009] Means by which the base component is fastened to the structure upon which the lock
is found and is such a manner that the lock's keyhole and the base element's hole
are aligned.
[0010] Means allowing for rotary movement thus permitting the placement of a covering component
on top of the base component.
[0011] Means of blocking the device which is placed upon it, subject of another patent.
[0012] Aesthetic and mechanical finishing aimed at rendering the device distinguishable
and to make it suitable for generalised use on all commercially available locks.
[0013] Means for fastening the device to a lock or fitting is such a manner as to integrate
it with the general system and to facilitate access to the opening mechanism.
[0014] Means of blocking rotary movements of the total-cover component.
[0015] Means of covering the model, rendering it aesthetically similar to others
commercially available.
[0016] The invention will now be described, in an illustrative but never the less not limited
manner, in its preferred form with reference to the figure in the attached designs
in which:
Figure 1 is a view of the device for the protection of keyholes;
The preferred form of the lock's keyhole protection utility model will now be described
in detail.
The device consists of:
A base (10) component
The component (10) in turn consists of various subcomponents. These are: One or more
blocking elements (11) allowing a device, subject of a separate patent, to be secured
to the base component;
A component (12) allowing the rotary movement of an over laying component, subject
of a separate patent;
a hole (13) through which access to the underlying lock is possible;
a component (15) consisting of a pin for preventing the rotations of a total-cover
device.
a component (14) which, for aesthetic purposes covers and hides the device in question
making it aesthetically pleasing.
[0017] The preferred form of the invention has been described in an illustrative but never
the lass not limited manner, it must be understood that any variations or modifications
may be made without falling outside the ambit of any protection rights, as defined
in the attached claims.
