(54) Device for the protection of locks


(57) A device for the protection of lock keyhole, characterised by the fact it includes:

a base, component (10), which at its centre has a hole through which access to the lock is possible;

one or more joints, component (11), permitting a device, which is subject of a separate patent, to remain fixed to the device;

a component (12) allowing the rotary movement of an overlaying component, subject of a separated patent;

a hole component (13), through which access to the underlying lock is possible;

a pin, component (15), for preventing the rotation of a total-cover device;

a component (14), used for covering the device rendering it aesthetically pleasing.






Description


[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.


Claims

1. A device for the protection of lock keyhole characterised by the fact that it comprises:

A base component (10) with a hole (13) that may either be circular or of another shape, through which access to the lock is possible;

means (12) allowing for rotary movement, permitting the placement of a covering component on top of the base component (10);

means (11) of fixing the covering component to the base component (10);

means of covering (14) blocking (11) and rotary - movement facilitating components thus attaining a satisfactory aesthetic result.

means of blocking rotary movements (15);


 
2. According to the previous claim, a device for the protection of lock keyhole, characterised by the fact that the base component (10) will have the diameter of preferably, but not exclusively, 50 millimetres, never the less being measurements greater or lesser than those falling within the ambit of the utility model.
 
3. According to the previous claim, a device for the protection of lock keyhole, characterised by the fact that the device and all its components, both separately and assembled, may have a painted, golden, brass, rhodium, silver or tropicalised plated aesthetic finish as well as undergo any other type of surface metal treatment or remain in an unfinished state.
 
4. According to the previous claim, a device for the protection of lock keyhole, characterised by the fact that the device and all its components, both separately and assembled, may be made of base metals, alloys, plastics or other materials.
 
5. According to the previous claim, a device for the protection of lock keyhole, characterised by the fact that the system for securing the covering component to the base component may consist of one, two or "n" joints, these joints having various shapes, forms, orientations and layout, or being symmetrical, asymmetrical or dissimilar, nevertheless remaining within the ambit of the protection rights of the utility model.
