DESCRIPTION

" SAFETY DEVICE FOR EMBEDDED ELECTRIC MECHANISMS "

This invention relates to a security protection device, also known as a thimble-proof device, designed for direct application to similar electrical mechanisms, such as switches, buzzer buttons, plugs and the like, with the spirit of preventing the detachment or removal of the outer plate from the assembly, whether accidental or deliberate, and thus preventing access to the interior of the mechanism; for this reason, the electrical assembly located here is perfectly protected, a set located in the zone provided for this type of built-in mechanisms.

As mentioned, the outer plates of the built-in electrical mechanisms are usually pressure-adapted, or maintained by the action provided by screws which are accessible from the outside; for this reason, the outer plates can be detached or removed at will, for the purpose of having access to the interior of the electric mechanism. The protection device of this invention provides a simple, economical and effective solution to the aforementioned problem 2, consisting in inserting, within the assembly of elements of which the mechanism is comprised, a safety frame, suitably attached to the metal structure which , in turn, allows the fixation of the mechanism in its place of installation. The outer plate is secured to this safety frame, first by fitting the side wall opposite the wall which characterizes the safety element, then by pivoting the entire plate until it is located in complete contact with the safety frame.

At this point, through the actuation of the locking pin located in the safety frame, which is the basic item of the safety device, this pin moves in the direction from the inside out, in such a way that its head is located in the interior of the hole that the outer plate exhibits in this place and for this purpose, thus the said plate being immobilized in its closed position, being impossible to remove or to detach it accidentally or by an unauthorized action or vandalism.

This safety device, which will be described in more detail below, should normally be applied in the embodiments given by way of example: the electric mechanism operated by means of a rocker switch; the dual electric mechanism operated by means of two rocker switches; the power outlet; 3 the power outlet with a protective cap; the power outlet with an immobilizer cap and telephone line connection, among others.

Figure 16 is a view equivalent to that of Figure 13, enlarged, in order to describe the locking pin 6 moved in order to carry out its locking function.

According to these drawings, the safety device which is the object of this invention is characterized in that it consists of the safety frame (1) which will be located on the metal structure (2), affixed to the latter in a suitable manner; the structure, in turn, is mounted and secured to an inner membrane (3) of the electrical mechanism, all of these elements being prepared for flush mounting, providing the assembly with a certain quality of watertightness.

In said safety frame (1) an outer plate (4) is suitably attached, the outer element being visible from the assembly of the electric mechanism, all of these elements being in their entirety, as previously mentioned, in-flush mounting. The rocker switch (6) is located in a central window (5) of this outer plate (4); is suitably abutting against the upper cover (7) of the electric mechanism (8), causes the necessary operation of the latter. The oscillation and attachment of the rocker switch 6 are defined by means of a support structure 9, bearing against the aforementioned metal structure 2, equipped with a transverse oscillation bar 10, in which the rocker switch (6) is adapted by its lower surface in order to perform its function correctly. The lateral movement of the support structure 9 is prevented by the safety frame 1 itself, while the rocker switch 6 prevents vertical pulling movement; this switch (6) is, in turn, retained by the outer plate (4). The safety frame (1) exhibits fastening and locking elements for maintaining the same in the metal frame (2); these consist of securing bolts (11) and locking clips (12), located at opposite ends of two of their sides. With the bolts (11) properly secured, with the locking clip (12) located below the corresponding screw head, this ensures their position and prevents their accidental prominence.

This repeated safety frame 1 has a prismatic thickening 13 on one of its sides and conveniently centered, inside which is defined the compartment for the locking pin 14, together with a nut, with a square shape , which allows the fixing of the outer plate (4) and prevents its detachment, either accidentally or due to improper action. This nut (15) comprises the element which allows the threading action of the locking pin (14).

Thus, the nut 15 is located via a rectangular slit 13a in said thickening 13, while the locking stud 14 was positioned through the front aperture 13b of the thickening 13 mentioned. The head 16 of the aforementioned locking pin 14 is located in such a way that it is accessible from the outside of the assembly when the outer plate 4 is located in the safety frame 1, (17) shown on the aforementioned outer plate (4) on one of its side surfaces and corresponding to the position of the aforementioned locking pin (14).

This pin 14 exhibits a normal thread in such a way that by operating its head, by means of a suitable tool, through the hole 17 of the outer plate 4, with an unscrewing action, the locking pin (14) will move inwardly, as seen in Figures 13 to 16, said pin head (16) being located inside the bore (17) of the outer plate (4), immobilizing it and preventing any movement thereof.

This locking action, by means of inwardly outward movement relative to the safety frame (1) in which it is mounted, of the locking pin (14), and the positioning of its head (16) inside the locking pin the hole 17 of the outer plate 4 is realized when said outer plate 4 has been correctly placed in the safety frame 1 itself, as can be seen clearly in Figures 11 and 12. The outer plate 4 ) is positioned by first locating the side opposite to that which shows the hole (17), to adapt on the side of the safety frame (1) also opposite that which the thickening (13) shows with the locking pin ( 14) inside. The adaptation is achieved thanks to some inner lower projections (18) on the outer plate (4) and which are located close to the grooves (19) which are in turn provided in the safety frame (1).

Once the protrusions 18 have been placed against the grooves 19, the outer plate 4 will oscillate to its initial position, the hole 17 being thus located opposite the head 16 of the locking pin 14), which is in its initial position " non-immobilized "; at this juncture, and by means of a suitable tool, the locking pin 14 will be moved in the direction from the inside out, until its head 16 is located inside the hole 17; in this way, the lifting of the outer plate 4 and, consequently, its removal or detachment from the safety frame 1 is prevented. 10

This safety device, according to the foregoing description, and which is the object of this invention, is of immediate application to other embodiments and applications of electric mechanisms, as can be seen in figures 2 to 6, in which the modes (8), operated by means of two rocker switch means (20), located on the oscillation cross bar (10) of the support structure (9), described in the figure 2. • Power socket assembly (21), with its square-shaped top socket (22) coinciding with the window (5) of the outer plate (4), as described in figure 3. • having a protective cap (23), which is hinged to an adapter (24) attached to the upper socket (22a) of suitable dimensions and having a securing spring (25) facilitating the movement of the protective cap (23). ) in the adapter (24), the latter being fixed later the safety frame itself (Figures 4 and 9a [9a]). A power take-off assembly (21a), having a protective cap (23), in turn exhibiting an immobilization cylinder (27) located in a cylindrical compartment (28) showing the above-mentioned protective cap (26) to this end. Said protective cap 26 preferably exhibits a transparent zone to be covered by a plate 29 suitably adapted to the positioning pressure, the protective cap 26 showing in turn the securing spring 25, , being suitably located and fixed to the adapter (24a) which exhibits on one of its inner sides a clip (30) for retaining the latch of the locking cylinder (27), all of which is described in figure 5. • Power take-off assembly for connection to a telephone line 31, located on the adapter 32, as is described in figure 6, being laterally secured by the security frame 1 (Figure 9bis [9a equivalent]).
