Description

The present invention refers to an intrusion-preventing device, arranged in the wall recess of an external frame of a building.
Nowadays, buildings, in addition to performance requirements, must have intrusion-preventing safety standards.
Within such context, mechanical safety systems are known, such as armored doors and related safety locks, armored windows and roller screens, fencings and gates.
Wired or wireless anti-theft systems are also known, with detecting systems of the types with magnetic contacts, infrared or ultrasound sensors.
It is further possible to understand how it is important to join different solutions and technologies, such as for example mechanics and electronics, without completely relying on a single safety system, since different solutions and technologies require different tools and skills to be violated.
However, the adoption of such arrangements and remedies, aimed to contain the risk of intrusions, not always can bring about good results in terms of prevention, and at the same time has higher costs and complications for a owner.
Known intrusion-preventing bars improve the safety of buildings, since they increase the closure points providing an obstacle to a break-through; moreover,, being fastened to frames, in walls and/or in floors, they keep the frames in position also in case of attempts to unhinge.
In particular, the following types of intrusion-preventing bars are known in the art:

a fixed bar, which is horizontally installed, such as for example the known Viro fixed bar, composed of a latch which engages recesses in a wall or fastened to a wall; it is actuated by a round cylinder with six small pistons, having an external protection against break-through and drills;
a universal bar, which can be installed both in a horizontal position and in a vertical position, and can be shortened or extended at the desired size with a suitable kit, such as for example known Viro, Blindo-sbarra or Mul-t-lock universal bars. DE-U1-20 2009 012959 , US-A-5 259 821 and US-A1 2010/170170 disclose other prior art intrusion preventing systems.

However, it is clear that the installation of the above intrusion-preventing bars needs fastening screws to be inserted, by making holes, on the frame itself, which therefore results disfigured, moreover not guaranteeing a high degree of intrusion prevention and stability of the bars. Moreover, known universal bars are equipped with a system for adjusting the bar length which is not efficient, not allowing a fine regulation of the bar length depending on the frame sizes.
An electronic universal bar is also known, which joins the safety features of the mechanical version with an intrusion-preventing vibration sensor, a GSM telephone switch and an environmental listening microphone; the movement sensor embedded in the frame detects possible attempts of intrusion and, simultaneously, sends messages to stored telephone numbers.
A low-voltage intrusion-preventing bar is also known, the Security Blind, which can be actuated with a remote control for opening and closing the bar itself, which has not any lock.
However, the known universal bar and intrusion-preventing Security Blind bar, in addition to having the problems of the above fixed bars and universal bars, require more maintenance deriving from the presence of electronic devices.
Therefore, object of the present invention is solving the above prior art problems, by providing an intrusion-preventing device which is simple, efficient and stable, arranged in the wall recess of an external frame of a building, which allows being quickly installed and uninstalled, and which provides an immediate signaling of a possibile intrusion for people which are inside a house or other room protected by the device itself.
A further object of the present invention is providing an intrusion-preventing device equipped with a fastening system adapted to confer stability and efficiency to such intrusion-preventing device, without fastening it to the internal surface of the frame.
A final object of the present invention is providing an intrusion-preventing device capable of being efficiently adapted to all sizes of a plurality of external frames.
The above and other objects and advantages of the invention, as will appear from the following description, are obtained by an intrusion-preventing device as claimed in Claim 1. Preferred embodiments and non-trivial variations of the present invention are claimed in the dependent Claims.
It is intended that all enclosed claims are an integral part of the present disclosure.
It will be immediately obvious that numerous variations and modifications (for example related to shape, sizes, arrangements and parts with equivalent functionality) could be made to what is described, without departing from the scope of the invention as appears from the enclosed claims.
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:
