STRUCTURE OF PROTECTIVE DEVICE WITH

BURGLARY REPORT.

DESCRIPTION

The present application relates to a security protection structure with alarm.

Currently, locks are known which are suitable for allowing the closing and opening of a door or gate which essentially comprise an opening cylinder equipped with a seat for the insertion of a suitable key suitable for enabling the cylinder to be activated. itself and then unlocking the lock.

These known cylinders are usually made of brass or in any case of materials which do not have a high mechanical resistance, thus lending themselves to be easily broken into by drilling and / or breaking and / or tearing.

In order to protect such known cylinders from possible break-ins, it is customary to fix to the lock, in a position such as to wrap one end of the cylinder, a special covering element or base of cylindrical shape, or other, which has a front opening partially occluded by a rotating protection disk in which a slot is made to allow the insertion of the key.

Said protection disk therefore constitutes a defense of the cylinder from drilling carried out with helical tips but at the same time allows the insertion and rotation of the key in the cylinder enclosed in the base.

These known bases, however, have a drawback: they are in fact mounted from the outside and fixed to the lock by means of screws recessed on the door panel which is made up of various materials such as wood, plastic, sheet metal, etc.

Normally between the panel and the base there is a space, or "light", which is covered and hidden by a decorative plate fixed to the panel.

The break-in is usually carried out by removing the decorative plate (18) Fig. 7, from the panel of the door or gate, where it is generally fixed with two screws removable from the outside, and inserting a tube or other tool on the protection of the cylinder in such a way that, by forcing it, the two fixing screws (19) Fig. 7 of the lock are torn and, at the same time, the cylinder (20) Fig. 7 is broken, thus making it easier to open from € ™ outside the door.

The aforementioned task and purposes, as well as others that will appear more clearly later, are achieved by a protective device structure, comprising a base where a housing has been obtained on the front part for the insertion of a luminous device that signals the operation of an alarm system which is activated in the event of a break-in brought to the protection itself.

Within the scope of the above aim, another important object is to provide an invention which can be made with known machines and plants.

Not least object is to provide an invention which is structurally simple and which can be applied to normal locks of the known type.

Further characteristics and advantages of the invention will become clearer from the detailed description of a particular embodiment, illustrated by way of non-limiting example in the attached drawings, in which:

Fig. 1 shows, in a perspective view, the invention applied to a lock of a door or door;

Fig. 2 is an exploded view of the invention applied to a lock of a door or front door;

Fig. 3 is a front perspective view with a decorative plate 17;

Fig. 4 illustrates, in a rear perspective view with a decorative plate 17;

Fig. 5 illustrates a rear view of the assembled invention;

Fig. 6 shows a section of the invention;

Fig. 7 illustrates how the protection is torn from its seat and the consequent rupture of the cylinder;

With reference to figure 1, the number (1) indicates the protection device applicable to a lock (2) that can be inserted in a door or front door (3).

With reference to figure 2 and following, the number (4) indicates the cylindrical base, which has an axial hole (6) on its front surface (5).

Said base (4) has, on the rear surface (7), two third blind axial holes (8), internally threaded and diametrically placed between them, said third holes (8) house two screws (9 and 10) for fixing said base (4) to said door or door (3).

In the base (7) in correspondence with one of the holes (8) there is a subsequent hole (11), passing through the body where an electronic container (12) is inserted in the terminal part of which a luminous lamp or lamp device has been housed. led (13) and on the inside other temperature or vibration sensors.

The sensor connection cables (14) pass through a groove (16) made on the threaded bar which constitutes the screw (10). The dimensions of the cables are such that they do not protrude from the radial dimension of the screw (10).

The electronic container (12) is inserted into the hole (11) until the terminal part of the luminous device (13) comes out and becomes visible.

Seen from the rear, the invention appears as in fig. 5. It is assembled by positioning it on the door (fig. 6) by passing the screw with the cables through the holes normally present in (2). The (1O) it contains,

by means of the nut 5) while the screw (9) is screwed normally.

The cables that come out through the slot of the screw (10) are supplied with power and to the alarm system. Once connected, the luminous device (13) will remain on continuously or intermittently, depending on the programming.

The passage of the cables through the slot (16) present in the screw [10) has two purposes, the first of mounting it on existing locks without having to modify the door or tampering with the lock by practicing additional ones that could invalidate the operation and in the second, much more important , Is to make the cable with the screw so that it does with this one. In the samo of an effrazian for tearing off the protection

ne, the screw (1 O) and the cables (14) contained therein break, putting the detection device in such a way as to be activated when there is,

current resulting from the breakdown of.

In addition to this detection, the system can be housed in the container

(12) of the temperature and vibration sensors that can work individually or simultaneously with the power failure and c h and can activate an alarm in the event that the protection (1) is overheated by puncture or brutally in order to make it fragile, while the vibration sensor can activate the alarm if there is strong stress on the door or lock or its protection.

It has thus been found that the invention has reached the field and has been predetermined having devised an extremely robust protection device structure particularly for a lock capable of protecting the cylinder of such a lock, detecting tampering and forcing attempts by signaling an alarm. The materials used as well as the dimensions constituting the individual components of the invention may be the most pertinent according to specific requirements.

The different means for carrying out certain different functions will not have to coexist only in the illustrated embodiment but may be present per se in many embodiments, even if not illustrated.

The characteristics indicated as advantageous, suitable or similar may also be missing or be replaced by equivalents.
