[0019]

In the drawings, two embodiments of the invention are shown. FIG. 3 shows an apparatus enabling the fragmentation of single-ply tempered glass, and FIG. 1 shows an apparatus for fragmenting double glazing.

In FIG. 1, an embodiment of a breaking striking device for tempered glass according to the invention is shown, which device is fixed to a tempered glass (11) by a chemical or mechanical system (7). 1). The support (1) acts as a sleeve for the movement of a piston (2) with a crushing tip called a striker (3). The piston (2) houses an energy storage element inside the spring (4). The piston (2) has a machined part which acts as a housing for a metal spherical ball called a retaining element (9) which keeps the spring (4) under compression between the piston (2) and the support (1). .

The support (1) further enables coaxial positioning of the push button (8) and movement towards the glass (11). This push button (8) functions as an opening element for the retaining element (9) when a slight axial movement in the direction of the glass (11) occurs due to the stepping of its internal machining section.

The support (1) is optionally for incorporating a light-emitting indicator into the device and / or for removing the safety pin (5), which allows quick installation or positioning even in poor visibility environments. Has an internal housing of an electronic device (10) for incorporating a system for generating an acoustic signal when starting.

The support (1) ensures the tightness and protection of the device mechanism against contaminants and holds the push button (8) in the activated position. In addition, the two radial holes allow the support (1) to allow the installation of the safety pin (5), and to secure this element and the push button (8) until the safety pin (5) is removed from its housing. The crossing does not activate the system and prevents any movement of the push button (8).

The safety pin (5) is a tamper proof seal (6)
Or may be configured to be visually clear to any attempt at removal.

The use of the device is very simple, since the safety pin (5) can be removed satisfactorily and a slight impact on the push button (8) is sufficient. The movement of the push button (8) enables the release of the holding element (9) and the movement of the crushing piston (2) and striker (3) towards the glass (11) by the stored energy of the spring (4). , Creates a high-energy impact that is concentrated in one point over the glass (11), which allows the total fragmentation of the glass (11).

The safety pin (5) may optionally be constructed of a material or shape for obtaining elasticity and resistance during calculated shear. In this way, in an emergency, if not removed, by hitting the push button (8) hard, the safety pin (5) is destroyed and the device operates as described above.

FIG. 3 illustrates an embodiment of monolithic tempered glass. In FIG. 3, the device allows fragmentation of the tempered glass by the energy applied to the push button without the use of springs as in FIG. In this embodiment, the device consists of the components described above. That is,
Support (1), piston (2), striker (3),
It has a spring (4), a pin (5), a seal (6), an adhesive (7) and a push button (8). The support (1) has undergone various modifications, omitting the housing of the holding element for holding the compression spring and the terminal horizontal projection.

The piston (2) is associated with the push button (8) and is maintained in the operating position by the light spring (4).

FIG. 2 shows an assembled front view of the device according to the invention, the push button (8) having a logo representing the purpose of the device.

Finally, the materials used for damping the components of the device proposed here, as well as the shape, dimensions and all other accessories that may be equipped, do not adversely affect the scope of the invention. As long as it is independent of the purpose of the invention.
