SAFETY STRUCTURE FOR BLOCKING SHUTTERS E

SHUTTERS.

The present application relates to a locking structure for securing shutters, shutters, shutters, shutters, French windows or other.

Nowadays there are various locking systems on the market for shutters (shutters, shutters, shutters, frames, French windows or other), "espagnolette type", that is composed of a bar or a vertical rod with two hooks at the ends, which are anchored to the latches, in the window jambs, and keep the same in the closed position.

The characteristic of these systems is that they can perform their locking function only when the doors of the frame are closed. They also have low tear resistance and can be easily excluded.

To further increase the resistance to break-ins, additional devices such as cross bars, bolts or other are normally added, which generally have the characteristic of operating only with closed doors, (it is in fact very difficult to keep the windows locked and safe when these are semi-open, since, through the space created with the opening of the doors, it is possible to easily reach the "blocking element" of the system from the outside and exclude it)

As a partial solution to this drawback, question no.

000148 of 11.10.2005 (patent 0001358723) which illustrates a protective structure comprising two substantially rectangular bases, antagonistic to each other, in which suitably shaped cavities or seats have been obtained to house rotating arms, which by engaging them prevent the outward opening of the doors. If properly rotated, a state is reached in which one of these arms, unlocked with a suitable knob, equipped with pins and springs and placed on the first base, can be pushed outwards thus allowing the partial opening of the doors.

On the first base, a specific shaping is obtained that allows the arm thus placed, to come into conflict with the base itself. This interference, between the first shaped base and the arm, prevents further movement of the arm itself and therefore blocks the leaves in a semi-closed position.

This known type of device therefore has some drawbacks, among which the fact that the doors deform due to their own weight and the changing atmospheric conditions, creating alignment problems between the two bases and / or between the seat of interference and the locking arm; furthermore, the assembly of the two opposing platforms must be carried out with a certain precision, not always obtainable, by inexperienced "fitters".

The main task of the subject matter of the present invention is therefore that of solving the technical problems highlighted, eliminating the drawbacks of the cited technique and therefore devising an invention which allows to keep the fixtures locked when these are half-open, practically realizing a closing and locking device which does not use locks or padlocks or other and which, while remaining accessible from the outside, cannot be disarmed.

Within the scope of the aforementioned task, another important object is to provide a device that can be armed and disarmed only with the leaves completely closed and that maintains the lock even when these are half-open.

Another important object is that the invention can be applied to new frames and also to others already in place without modifying their functionality.

Not least object is to provide a device which is structurally simple and has low manufacturing costs and easy to assemble.

The task and the other purposes mentioned above, as well as others that will appear more clearly later, are achieved by a safety structure comprising two fixed bases, (which we will call base "A" and base "B"), anchored by screws, bolts or other, on the doors of the frame. A bolt-action sliding rod is mounted on structure "A", with predefined stop positions, selectable by means of the knob fixed on the sliding rod itself; this, sliding in its internal guide, engages the other structure "B" positioned on the antagonist frame. Depending on the stop position of the knob, the locking function is obtained with fully closed leaves or the locking function with semi-open or compass-type doors.

Further characteristics and advantages of the invention will become clearer in the detailed description of some details, but not exclusive embodiments illustrated for indicative and non-limiting purposes in the attached drawing tables from which:

In the following embodiment examples, individual characteristics reported in relation to the specific examples, may actually be changed with other different characteristics, existing in other embodiments.

It should also be noted that everything that in the course of the procedure for obtaining the patent turns out to be already known, is intended not to be claimed and subject to excerpt (disclaimer) from the claims. With reference to the attached figures, it is indicated with no. 1 a locking device structure applicable for example to a double-leaf door, to window frames, shutters, windows or other.

Advantageously, the structure comprises a base 1, substantially in the shape of a parallelepiped associated or associable with a rod or bolt 2 which slides in a seat 3. This rod is activated by a knob 4 which moves inside the slot 5 ( fig. 4).

The knob 4 is kept in the outermost position, with the ring 9 located outside the slot 5, due to the effect of the spring 10; this allows it to slide freely along the entire length of the slot until the bolt rod is completely inserted into the antagonist structure 6 and then the device is completely closed (fig.6, fig.5 and fig.2).

Advantageously, in the front part of the structure 6, a suitably shaped nib 15 has been obtained, which allows the slot 16, obtained in the bolt rod 2, to hook the nib 15 to the protuberance 14 in the locked position (fig. 7 ).

Advantageously, in the front part of the bolt rod 2, a slot 16 has been obtained, and a suitably shaped protuberance 14, which can be grafted onto a fixed nib 15 in the structure 6 (fig.7).

Advantageously, in the structure 1 a further slot of a larger size with respect to the slot 5 has been obtained, suitable for the sliding of the ring 9 of the knob 4. At the end of the slot 12 a circular slot 17 has been obtained which is deeper than the seat 12 , able to accommodate

the ring 9 of the knob 4 as the locking end-stroke of the knob itself (fig.6).

By pressing the knob 4 (overcoming the antagonism of the spring 10) towards the inside of the seat 11, until the ring 9 is completely inserted in the slot 12, and moving it from the starting station 8 to the stop station 13, the part ends 14 of the bolt rod 2 is in the optimal position in which, by pushing the two doors of the window frame outwards, the seat 16 of the bolt rod itself automatically enters the lug 15 (of the base 6) and it engages in the locked position (fig. 8). With the doors of the window arranged like a compass in a semi-open condition.

This coupling system in the semi-open condition is obtained by pushing the doors outwards so that their rotation allows the system to engage (fig. 3). Once in position, the ring 9 of the knob 4 enters the circular groove 17 blocking any movement of the bolt rod 2. This determines the safety closing condition of the semi-open rods (fig.8). The only possibility of opening is to axially align structure 1 with structure 6; to do this, push the knob 4 so that the ring 9 comes out of the slot 17 and the knob and the bolt rod 2, integral with it, can slide freely inside the slot 12, until position 8 is reached ( fig. 4). Advantageously, the disengagement of the nib 15 is obtained only with the total and complete alignment of the structures 1 and 6 (fig. 4).

It was thus found that the invention has achieved the intended aim and objects, a locking structure having been devised which allows the doors to be kept safely even in the half-open position.

The invention is naturally susceptible of numerous modifications and variations, all of which are within the scope of the same inventive concept.

The materials, as well as the shapes and dimensions that constitute the individual components of the invention, and the invention itself, may of course be more pertinent according to specific requirements.
