Abstract

Security shutters. They consist of a sheet steel structure (8) with a perimeter reinforcement, with a wooden sheet (10) attached as an aesthetic finish. The shutters (1) are arranged on the inside of the window (2) so that the wooden sheet (10) is directed outwards. Being hinged on the frame (13) of the window, when they are open they offer their wood finish (10) towards the interior of the cabin, while when they are closed they are perfectly visible from the outside through the glass (11). It has also been provided that between the steel sheet (9) and the wood sheet (10) there may be a thermal insulation layer (9), in this case having a wood sheet (10) materialized by a wood veneer, instead of plywood board. Being the shutters (1) mounted inside, they are perfectly protected by the glass (11), from inclement weather, changes in temperature, humidity and excessive sunlight.

Description

Security shutters.

Object of the invention

The present invention, as expressed by the set forth in this specification, refers to some security shutters that are made by steel structure, with perimeter or folding profiles perimeter, or box modeling, with thermal insulation and finish with wood veneer as termination face. The set also of aesthetic and economic results, it offers a great quality of safety protection, a darkening system cabin and aesthetic finish.

There is a current problem around the window security and other vital factors, in special thermal insulation and acoustic insulation of windows and doors as well as darkening systems and final aesthetic result.

Background of the invention

The door and window industry for exterior is currently in a strange point due to that more and more society demands greater security and protection against robberies and robberies, and current and classic solutions they demand other solutions that have not yet arrived.

It seems a paradox but except for the use of large safety glass laminar systems, whose prices they are highly prohibitive for most users, the current technique for security windows, only available in general lines of supplementary protection elements, such as security bars made of steel profiles and the bars of steel slats.

As for the security bars made with steel profiles, we must say that they represent the most extended, although in spite of different factors such as:

- They always have weak points, because they can open with hydraulic jacks, manual and with lever action with other elements, thus offering a very deep security limited

- It is sad and uncomfortable that these elements they are always arranged in the hollow, as they are usually fixed, since that practitioners have even more weaknesses. Therefore, from outside, buildings with this type of protection do not usually have a good aesthetic result, because safety always prevails before the aesthetic. From the inside, the problem is even worse if possible, since the gaps of the buildings, either windows or doors, must be a relationship of the building with the outside, a relationship of views and landscape, a sense of freedom, and without However, the gaps with this traditional system are doomed to a "landscape behind bars", even to instill users claustrophobic reactions and evacuation problems in case of fire for low buildings.

- They are elements made of steel and outside, the multitude of weaknesses in everyone's welds the elements is wide, being therefore excessively weak against corrosion since they have excess steel surface exposed to the outside, and have fully horizontal faces that allow to accumulate on them the remains of rainwater or condensations Therefore, bars of this type usually require major maintenance, consisting of sanding and repainted newspapers.

As for the bars of steel slats, which due to its density, to enable the views must be practicable in a folding or sliding way, they have the following features:

They are safer than those described. previously, although they do not represent a 100% guarantee of invioliability of the hole.

With respect to the previous ones they have resolved the issue of views, since being practicable, if you want you can allow views of the outside landscape without producing Claustrophobic sensations or prevent the evacuation of buildings low in case of fire. In addition, they have aesthetic results top. However, since the element is outside the facade, opening and closing operations are a bit more cumbersome, requiring movements and efforts of the human body that are a bit heavy or not suitable for all ages and physicals conditions. Likewise, being elements abroad and by the same reasons described in the previous type, need periodically high maintenance operations, consisting of Sanding and repainting.

As opposed to the previous one, this system is or  It is usually much more expensive (although there are locksmith jobs for quite complicated and expensive pipe railings).

There seems to be no other security systems, Well, it is not worth mentioning aluminum irons, without any security due to the weakness of the material, as well as the aluminum shutters and other materials.

Regarding commercial slat closures metal rolling, scissors closure, etc., without entering in details they seem to have their own scope, without However, they lack aesthetics for most users, they are uncomfortable and loud, heavy, expensive (especially if to compensate weight and noise are automated). And something characterizes them, everyone has the lock visible to the outside, constituting the weak points from the same.

Regarding isolation issues thermal, current systems for window insulation and exterior doors of a building, are fundamentally resolved of  two different ways: the first one through overlapping two different windows creating an air chamber each. Duplicating therefore the inversion of the hole and its corresponding protection and maintenance systems. The other shape is a system that uses glasses forming sandwich between yes, materialized by a layer of glass, an air chamber that must be prepared to absorb excess moisture and condensations inside (which is not practicable) and finally Another glass inside.

This last system is expensive, since it is giving the glass insulating properties term, when its Transmission coefficient is not especially low. However yes condensation in these crystals is being minimized, although not always of course they achieve this goal.

In addition, the carpentry to be housed these special crystals, due to the thickness they consume, must be also special, since they have to house a set of thick crystals and have to be reinforced by double weight which constitutes the main material of a window: glass.

These glazing systems are quite expensive

Attending now to isolation issues acoustic of the current systems for windows and doors the exterior, are made by using double windows, and / or with the use of large glass thicknesses, since only with mass is They get good insulations.

But once again they try to give isolation with the same material that serves as transparency, although the acoustic insulation against thermal glass has a little more of sense, since glass is a heavy material. However in An expensive and delicate material.

In matters of aesthetics it is clear that a building is directly related to a system of protection or security enclosure of windows and doors, already which are usually part of the outer elements of display.

However, it is true that any of the described loses the concept of unity to buildings related to the outside, as much as you invest in good windows (eg wood), the overall aesthetic makes the fence (for example bars) have too much importance in the hollow.

In addition to the current commented systems, they are exclusively made of steel and there are no other systems Reliable in aluminum, PVC, wood, etc.

Description of the invention

In general, the shutters of security object of the present invention, which have application both in windows and doors, have a structure defined by a steel plate with perimeter profile or equipped with a perimeter folding, or box modeling, having an iron of thermal and acoustic insulation and a wood veneer finish as termination face, being able to replace the sheet of wood termination and thermal insulation, by board single-sided plywood, at the cost of less insulation Thermal and more cost.

The basic feature of the invention has been to cite the fact that the shutters are always mounted inside the cabin, the system being protected from safety of climatic agents, of temperature changes and humidities and excess of sunshine.

Therefore, for being inside the buildings, it is easier to handle and practice them, deciding even if they want to open completely or only part, since at the same time it has security functions and darkening.

Due to the circumstance that in the calculations of thermal and acoustic insulation, the windows so far are calculated by the characteristics of the glass and the carpentry of sustenance, it should be noted that there are two different calculations for the carpentry that will carry this system that is intended register, since on the one hand, being open they keep logically the same characteristics as the current ones; Y closed, because they involve two sheets and a camera, the first sheet is the glass, the air chamber, for example 25 mm., and the second sheet that is defined by the shutter made with steel sheet, thermal insulation and wood veneer. According to this, The security system that is recommended has:

- Great thermal insulation because it is not tries to grant greater thermal insulation by prefabricated assembly of several glass sheets with camera inside, but with this system, the glass is unique, with the missions that belong as such, and the isolation is done by a air chamber that being practicable there are no risks of condensation inside, plus a layer of thermal insulation specific, much lower in the transmission coefficient calorific

- A great sound insulation, since in lines general and except for specific essays where the fasteners, acoustic bridges, etc., insulation Acoustic of an element is a proportion of the logarithm of the mass, and unquestionably, the shutter in the closed position can get to offer sound insulation outside of any proportion with what is currently existing, since a glass sheet, a camera of air, a thermal insulation (which however dampens the sound impacts) and finally a steel sheet of 2 to 4 mm., they suppose a great acoustic insulation, to use (closed the shutter) at those times when a higher exterior insulation.

It is worth mentioning that the situation of calculations of thermal and acoustic coefficients of the gaps, despite constitute a window or a natural lighting hole and at the same time a natural ventilation hole, are made in the hypothesis closed hole. For this reason, and for the possibility of having gaps thus arranged at the times of the year that are required at throughout the different hours of the day for thermal issues, and in the specific moments of the life of the hole when punctually a good and great sound insulation is required, the calculations that they could offer windows in terms of their characteristics, would be the computations made with a closed shutter.

To facilitate the understanding of characteristics of the invention and forming an integral part of This descriptive report is accompanied by sheets of plans in whose figures, with an illustrative and non-limiting nature, have been represented the following:

Description of the preferred embodiment

Referring to the numbering adopted in the figures, we can see how the security shutters, which The invention proposes are formed by two hinged sheets (1), each of which folds in turn along the middle line. The Window (2) is two hinged sheets (3). Each of the parts of a shutter sheet (1) has been referenced with the number (4). Figure 1 shows the two shutters (1) totally open and with its leaves (4) folded in turn in half, this front view corresponding to the window (2) from the interior of the house. Reference (5) designates the flashing perimeter of the fence (6) at its junction with the wall (7) (see figure 3).

Figure 2 shows the same shutters (1) in a 50% opening position.

Figure 3 clearly shows the composition structural of the shutter (1), materialized by the flat galvanized steel (8), thermal insulation (9) and plating wood (10). The glass (11) of the window 2 is located in the exterior and protects the sheet metal from the weather wood (10), this being visible from the outside, as well as it is in this exemplary embodiment shown in the figures, the wooden frame formed by the rushes (12) that are glued with transparent silicone to the glass (11) and the frame metallic (13) of the leaf (3) of the window (2).

The hinges of the leaves (3) of the window (2), are referenced with the number (14) and the articulation of the shutters (1) with respect to the frame (13) of the window leaf (3), with the number 15. The two parts of the sheet (4) of Shutter (1) articulate each other on the hinges (16).

With this provision and as observed in the Figure 3, an air chamber (17) is formed between the glass (11) and the shutter (1) that contributes to the isolation of the inner layer (9) of the shutter (1). When the security shutters arranged inside the cabin, the security system of the agents is protected climatic changes in temperature and humidity and excess of sunning, as we indicated earlier and that constituted one of the basic features of the present invention.

Making special reference now to figure 4 where three opening positions are shown schematically and closing the window (3) and shutter (4) sheets, we can see how at the top the window sheet (3) of the left is closed with the safety shutter (1), in so much so that the one on the right side is closed at 50% since both parts (4) of the shutter (1) are folded one over the other. In the central area of the scheme it is observed that the sheet of window (3) on the left is also closed by the shutter (1), while the leaf (3) on the right is totally devoid of the shutters (1), being both parts (4) that make it up, folded one on top of the other by the interior of the house. Finally, in the part scheme bottom shows both windows (3) and shutters (1) in a fully open position, adopting in this case the shutters (1) on either side a different position put that in the left part the leaves (4) are in extension, while on the right side they are overlapping.

When the shutters are open the wood (10) aesthetic finish is visible from inside the housing, whether it is through the glass (11) (when the window (2) is open), as if it is observed directly if the window is closed.

Figures 5 and 6 show a shutter safety (18) mounted on a window (19) of a sheet folding, according to a view from the inside.

Figure 7 shows the same window (19) of figure 5, with the shutter (18) in the closed position and according to a view from the outside. The different positions a), b) and c), of this figure, show different designs to configure the exterior appearance of the wood finish (10). In position a) the design represents wooden slats (20), like the shown in figure 5; in position b) there is a combination of sheets of different lengths and amplitudes; and in position c) the design is shaped by a repeated plurality of plates  rectangular (21).

Claims (2)

1. Security shutters, for application to windows and doors, characterized in that they are constituted by a steel sheet structure (8) with perimeter profile, which is arranged on the inside of the window or door and hinged to the frame (13) of the same, covering the outer face, visible through the glass (11), with wood sheet (10) as an aesthetic finish. 2. Safety shutters, according to claim one, characterized in that the steel sheet (8) has a thermal insulation layer (9) attached directly on its face facing the outside of the passenger compartment, which is thus intermediate in relation to the sheet wooden (10) aesthetic finish.
