Description

Technical field

[0001] The present invention refers to the technical field relative to the safety devices for preventing robberies and burglaries inside houses.

[0002] In particular, the invention refers to an innovative anti-burglary and anti-intrusion system applicable on any kind of existing door.

Background art

[0003] In order to prevent robberies inside houses, everyone knows that various devices are nowadays used, such as alarms and/or anti-burglary doors.

[0004] Although alarms are reliable systems, they can anyway be eluded by thieves. It is in fact known that all electronic technologies result outdated soon after their launch to the market and therefore easily subject to attacks that can elude their functionality. Moreover, it is known that all electronic systems have a lower reliability with respect to mechanical systems, in the sense that the probabilities of breakdown and malfunction of an electronic device are generally higher and hardly predictable with respect to a mechanical device. In addition, all alarms base their functionality on the sound of the siren which, due to the habit of hearing them also accidentally, they are no more taken into serious consideration.

[0005] In order to improve anti-burglary safety, many users prefer to resort to the so-called anti-burglary doors, which result particularly robust and resistant to external attacks. However, anti-burglary doors, as any other type of door or gate, can be tampered directly from the outside through an intervention on the lock or on the hinges for fixing and framing the door to the walls. How ever a lock may be robust and structurally complex, it never results impossible to attack, above all if the thief has the necessary time at his disposal to act and open it.

[0006] Although such doors are significantly expensive, precisely due to their reinforced structure, they cannot guarantee complete safety against an intrusion.

[0007] To that aim, door reinforcement solutions have been proposed, for example in German patent DE329455 or in German patent DE362198.

[0008] Such reinforcement systems are based on the use of a bar that can be lifted/lowered with rather complex manual systems. Such systems are not efficient since they imply very old and not much reliable manual lifting systems of the bar. Accordingly, apart from the uncomfort of the manual activation, such systems do not allow the use of heavy bars just because lifting them would result difficult, above all by old people.

[0009] The most recent patent publication US 4349233 proposes a solution for improving the resistance of a door from an eventual burglary attack with an automated system. Such a solution proposes a dented bar which is arranged in a sliding manner on a horizontal guide and is controlled according to a horizontal motion of an electric motor that conducts in rotation a gear meshed with the bar. The bar traslates in that way between a position in contact with the door for blocking it and a position outside the door width.

[0010] Such a solution, however, is extremely cumbersome since it requires the permanent presence of a support and sliding apparatus for a big bar permanently arranged at the level of the door. In such a way, also in the unblock condition, the bar will be visible together with the complex apparatus that controls its movement and that supports it.

Disclosure of invention

[0011] It is therefore the aim of the present invention to provide an anti-intrusion device that solves at least in part said drawbacks.

[0012] In particular, it is the aim of the present invention to provide an anti-intrusion device that results of aid to common doors, giving them particular anti-burglary characteristics and such as not to result damageable from the outside.

[0013] It is therefore the aim of the present invention to provide an anti-intrusion device that allows to reinforce the existing door eliminating the need for the door to be substituted with a specific anti-burglary door.

[0014] In particular, it is the aim of the present invention to provide an anti-burglary device that can be easily and automatically operated by a user between a barrage position and an unblock position and that, at the same time, can be well integrated in the home environment in such a way as not to result visible or cumbersome in non-use conditions when the door is unblocked.

[0015] These and other aims are therefore reached with the production of an anti-intrusion device 1 for doors and windows, as per claim 1.

[0016] In particular, said anti-intrusion device (1) for doors and windows comprising:

• A barrage element (2);
• Support means (3) for holding the barrage element (2) opposed to the door or the window in such a way as to impede the opening of it.

[0017] In accordance with the invention, a winder (5) is included which, in use, results placed above the barrage element (2). At least one tape (10) results connected to the barrage element (2) on one side and to the winder (5) on the opposite side. In this way, a rotation of the winder (5) in a direction causes a winding of the tape (10) on the winder (5), with relative lifting of the barrage element (2) from the support means (3) to allow the opening of the door. On the other hand, the rotation in the opposite direction causes an unwinding of the tape (10) from the winder (5) with relative lowering of the barrage element (2) on the support means (3) for causing the block of the door.

[0018] Such a solution allows to obtain a functional device which results above all well integrated in the environment and less visible, since the winder is now placed above the bar. In this way, when the bar is lifted, it liberates the door and at the same time it goes out from the field of view or, at least, results much less visible since it is suspended above the door itself.

[0019] In order to be able to wind/unwind the tape in an automatic manner, the winder (5) further comprises an electric motor (6) and a rotating shaft (7) connected to the motor (6). The rotating shaft (7) is provided with at least one pulley (8) on which to wind/unwind said tape (10).

[0020] Advantageously, the automation through the use of the electric motor allows to include a remote control device for controlling from remote the activation of the motor (6) that conducts in rotation the rotating shaft (7).

[0021] In this way, the barrage can be activated when the user is outside the house and can be removed before coming home.

[0022] Advantageously, a central control unit (14) can be included for controlling the manual activation of the electric motor (6).

[0023] Advantageously, the central control unit (14) can be arranged inside the house.

[0024] Advantageously, on the rotating shaft (7) two pulleys (8) are included diametrically opposed and two tapes (10) that wind respectively on said pulleys.

[0025] Advantageously, the bar (2) includes a register (11) to which each tape (10) included is connected.

[0026] Advantageously, the support means (3) comprise at least a first (3) and a second hook (3) arranged in use diametrically opposed with respect to the width (12) of the door (4) or of the window (4) in such a way as to retain the barrage element (2) opposed to the direction of opening of the door or the window.

[0027] Advantageously, the winder (5) is arranged inside a frame (13) configured so that it can be hung to a wall.

[0028] Advantageously, two micro switches are included electrically connected to a position sensor of the bar in such a way as to indicate to the user the lifted or lowered position of the bar by means of a specific light.

[0029] Advantageously, such switches include a green light for indicating that the bar is lifted, a red light for indicating that the bar lies on the hooks (3), and an orange light for indicating the bar in the phase of movement.

[0030] Naturally, other colours could be used for indicating the positions occupied by the bar.

[0031] Advantageously, a buffer battery can be further included for feeding the electric motor (6) in case of lack of home electric current.

[0032] Advantageously, an emergency servo-motor is included fed by a battery and that substitutes the primary motor in case of breakdown.

[0033] Advantageously, the barrage element (2) is a bar (2).

Description of one preferred embodiment

[0035] In the annexed figures, an anti-burglary device 1 is described in accordance with the present invention.

[0036] In figure 1 a schematic axonometric view of such device 1 is represented. A barrage element 2 comprises a simple bar 2, for example made of steel or another material suitable for the purpose. The bar, as shown in figure 1, results applicable opposed to the door from the inside in such a way as to create a barrage that impedes the opening of it. To that aim, the bar 2 is connected, by means of appropriate connection elements 10, to actuation means 5 that allow the vertical lifting and lowering of it.

[0037] Going into the descriptive detail of the invention, as shown in figure 2, said actuation means 5 comprise a winder 5 comprising an electric motor 6, for example for blinds, connected to a rotating shaft 7 and that serves for wrapping and unwrapping one or more tapes or wires 10 (of fabric or metal wire). The wires 10 (in figure 1 two of them are shown) are connected to the bar 2 in such a way that through the rotation of the shaft 7 in one direction a winding of the wire 10 is obtained that determines a lifting of the bar, while an opposite direction of rotation implies a lowering of such bar.

[0038] Going back to the tapes or wires 10, they must be appropriately dimensioned in such a way as to hold the weight of the bar 2 without incurring breakages. Accordingly, steel tapes can be chosen, as already said, but also made of a sufficiently resistant nylon, or even suitable chains. The two or more tapes 10 are arranged with respect to the bar 2 in such a way that the bar is lifted and lowered, keeping itself in a substantially horizontal balance position.

[0039] To this aim, figure 3 shows a detail of connection of the tapes to the bar 2 through appropriate registers 11. The positioning of each register with respect to the overall length of the bar is such by which the bar is not inclined during the movement. Naturally, more than two registers can be positioned (for example three, two laterally and one centrally) without for this moving apart from the present inventive concept. In this way, the load is distributed on a greater number of tapes, allowing to undersize them. Even a single tape could be used for the purpose, well-centred and appropriately dimensioned.

[0040] As shown in figure 1, appropriate support means 3 comprise two or more elements in the shape of hooks 3 (for example L-shaped) and arranged in an opposed manner with respect to the width 12 that defines the opening into which the door or the window is installed. Figure 1, just as a way of example and therefore not limiting for the invention, shows a door 4 that encloses such width 12. In this way, when the bar is arranged into said hooks 3, it is placed substantially close to the door, producing a barrage to the opening of it. The hooks 3 are therefore fixed to the wall on the side of the direction of opening of the door.

[0041] Figure 2 shows in detail the winder 5 configured for winding/unwinding the tapes 10 in such a way as to lift/lower the bar 2 from/towards the support means 3. To that aim, the winder results arranged above the hooks 3 and, preferably, above the width of opening of the door or the window.

[0042] In this way, the opening of the door is not impeded by the presence of the winder hung to the wall above the door and with a width maybe greater than that of the width of the door itself.

[0043] The winder 5 comprises the rotating motor 6, which activates the rotating shaft 7, and containing an electronic central unit with a high-precision electronic limit switch system.

[0044] The shaft has connected on it two or more pulleys 8 (for example three) around which the two or more tapes 10, respectively, wind and unwind. Figure 2 shows the rotation axis 9 of the shaft. Any number of pulleys can be included arranged along the bar 2 on the basis of the number of tapes arranged.

[0045] The entire winder 5 is arranged into a containment frame similar to those of a wall conditioner, in such a way that they can be easily arranged on a wall above the door.

[0046] The motor further includes a radio frequency receiver of 433,92 MHz for the use of a control remote device with Rolling Code technology (with code at 64 bit, 18 billions of billions of combinations).

[0047] In this way the user, once the house has been closed, can activate the device for barring the door from the outside and can activate it again when he comes home to liberate the door and get into his house.

[0048] Figure 4, last, shows a section wherein the positioning of the bar with respect to the door or the window when placed into the hooks 3 is highlighted. It is therefore preferable that the hooks are such as to keep the bar in contact with the door for avoiding that shakes on the door during a burglary attempt cause the breakage of the hooks.

[0049] Such device 1 is provided with a central control unit 14 (as shown in figure 5) for activating manually the movement of the motor exactly as a blind for shops or garages.

[0050] The central control unit can be placed inside the house and/or externally in a hidden spot only known by the user/owner.

[0051] The central control unit 14 results connected to the motor through an electric wire.

[0052] The device described further includes the use of 2 micro switches capable of indicating to the user the position of the bar inside the house. In particular, a green light indicates that the bar is placed in the split, a red light indicates that the bar lies on the L-shaped hooks and, last, an orange light indicates that the bar is in movement independently of the fact that it is opening or closing.

[0053] Figure 8 shows a flowchart relative to further additional functioning safety. In particular, it indicates a buffer battery for feeding the motor in case of lack of home electric current supply and an emergency servo-motor that substitutes the main motor in case of breakdown. The servo-motor has a feeding battery of its own.

[0054] In use, therefore, as shown in figure 6, the motor can be controlled at a distance in such a way as to determine a rotation that causes the unwinding of the tapes and therefore the lowering of the bar. The bar is lowered up to reaching the hooks in such a way as to bar the corresponding opening. The directions of the arrows of figure 6 show the direction of unwinding of the tapes and therefore determine the rotation corresponding to the shaft 7. For clarity purposes, both the containment frame 13 of the winder 5 and the door 4 have been indicated with a dotted line. Subsequent figure 7, on the other hand, shows a re-winding phase that brings the bar 2 close to the winder and therefore externally to the width of the opening/closure of the door or of the window.

[0055] An user can therefore go out of the house and control at a distance through the remote control device the activation of the bar in such a way that it bars the door. When he comes home, always through the remote control device, it is possible to activate the lifting of it in such a way that the opening of the door is possible.

[0056] It is therefore clear that such a barrage device from the inside of the door results absolutely not accessible and therefore not damageable from the outside. Accordingly, it results particularly safe from intrusion attacks.
