Description

Safety device for mechanisms recessed electric.

The present utility model lies in a safety protective device, also known as Vandal-proof, designed for direct application in similar electrical mechanisms, such as switches, push buttons, plug bases and the like, with the purpose of avoid detachment or separation of the outer plate from the set, either accidentally, or intentionally, and thus preventing access to the interior of the mechanism, by what the electrical assembly located there is perfectly protected, set that is located in the area arranged for this type of recessed mechanisms.

As stated, the outer plates of the electrical mechanisms that are installed recessed, are placed generally under pressure or by means of the fastening obtained by screws accessible from the outside, which is why said outer plates can be detached or separated from will, in order to access the inside of the mechanism electric.

The protective device of the present invention offers a simple, economical and effective solution to problem noted above, consisting of the introduction, within the set of elements that make up the mechanism, of a safety frame, properly fixed to the metal frame that, to in turn, it allows the mechanism to be fixed in place of its installation.

The plate is fixed on this safety frame exterior, first fitting the side wall opposite the wall provided with the security element, tilting immediately the entire plate until it is placed in full contact About the security framework.

Acting from that moment on the locking screw located in the safety frame, and that is the basic part of the safety device, this screw, is moves outward, so that its head is located in the hole that the outer plate has for that purpose in that place, thus said plate being locked in its closed position, not being able to separate or detach accidentally or by an action Incorrect unauthorized or vandalism access.

According to these drawings, the device Security object of the present invention is characterized by consist of the security framework (1), which will be located by above the metal frame (2) attached to it properly, frame that in turn is arranged and fixed on a membrane internal (3) of the electrical mechanism assembly, all ready for recessed installation, providing a certain degree of tightness to the whole.

On said security framework (1), it remains conveniently fastened, an outer plate (4), visible element external of the electrical mechanism assembly, installed, such as It has been noted above, fully embedded.

In the central window (5) of this outer plate (4) the rocker switch (6) is placed, which, conveniently supported on the upper cover (7) of the electrical mechanism (8), causes the necessary actuation of it.

Balancing and fixing the rocker (6) is defined by a support frame (9), supported by the referred to metal frame (2) and provided with a crossbar of balancing (10), on which it is fitted, by its lower part, the rocker (6), to carry out its function correctly.

The lateral movements of the support frame (9) are prevented by the security framework itself (1), while the rocker (6) prevents the vertical movement of extraction, key (6) which, in turn, is retained by the plate exterior (4).

The security frame (1) is provided with fixing and locking elements for fastening to the frame metal (2), consisting of fixing screws (11) and locking clips (12), located at opposite ends of Two of its sides. Properly fastened the screws (11), with the locking clip (12), located below the head of the corresponding screw, ensures its position and prevents its accidental detachment

This repeated security framework (1) has, in one of its sides, and conveniently centered, a thickening prismatic (13), inside which the housing of a locking screw (14), together with a nut (15), contour square, which allows the fixing of the outer plate (4) and prevents its detachment, both accidentally and by an action wrong. This nut (15) constitutes the element that allows the threaded locking screw (14).

Thus, in said thickening (13), it remains placed, through a suitable rectangular slot (13a), the nut (15) while the locking screw (14) has been positioned by the front opening (13b) of the mentioned thickening (13). The head (16) of said locking screw (14) is located so that it is accessible from outside the set, when the outer plate (4) is placed on the frame safety (1) through a hole (17) that the mentioned outer plate (4) has a corresponding side face with the position of said locking screw (14).

This screw (14) is of normal thread, so that by acting, through the right tool, through the hole (17) of the outer plate (4) over the head (16), with the unscrew the locking screw (14) will move out, as seen in figures 13 to 16, remaining said head (16) located inside the hole (17) of the outer plate (4), blocking it and preventing any displacement of it.

This blocking action by outward displacement, with respect to the frame of security (1) where it is located, of the locking screw (14), and the positioning of its head (16) inside the hole (17) of the outer plate (4), is carried out when said plate exterior (4) has been placed correctly on the own security framework (1), as clearly seen in the Figures 11 and 12.

The outer plate (4) is placed by placing first, the opposite side to the one with the hole (17), embedded on the opposite side, also, of the security frame (1) to the one who has the thickening (13) with the locking screw (14) inside.

This lace is made thanks to some protrusions internal lower (18) that has the outer plate (4) and that they are located next to corresponding recesses (19) that, to in turn, it has the security framework (1).

Once the projections are arranged in this way (18) against the recesses (19), the outer plate (4) will be folded down leaving then the hole (17) located in front of the head (16) of the locking screw (14), which is in its initial position of "no blocking", moment after which, by means of a suitable tool, we will proceed to move the screw of block (14) outwards, until its head (16) is located inside the hole (17) thereby preventing the elevation of the outer plate (4) and, consequently, its separation or detachment of the security frame (1).

This safety device, in accordance with the description above, and which is the object of the present invention, is immediately applicable to other embodiments and applications of electrical mechanisms, as seen in figures 2 to 6, in the following embodiments are represented:

-

Double mechanism assembly (8), with drive by means of two swinging semitracks (20), which remain located on the balancing cross member (10) of the support frame (9), represented in figure 2.

-

Plug base assembly (21a) provided with a protective cover (26), provided in turn, with a cylinder lock (27), placed in a cylindrical housing (28) which for that purpose has said cover (26). That cover protective (26) preferably has a transparent area that covers with a plate (29) duly fixed under pressure, provided, likewise, such a protective cover (26) of the fixing spring (25), being properly located and fixed to the adapter (24a), provided on one of its inner sides of a projection (30) for the cylinder lock latch retention (27), all represented in figure 5.

Base set for connection to a telephone line (31), located on the adapter (32), as shown in figure 6, which is  fixed laterally by the safety frame itself (1) (Fig. 9bis).

In all embodiments, cited by way of For example, the introduction of the framework of safety (1) that allows fixing and locking of the plate exterior (4), which constitutes the desired protection.

Described in maximum detail the characteristics of the safety device object of the present invention, it should be noted that the essentiality thereof will not be affected if dimensions, shapes, colors and finish or types of materials used in the practical realization of the device are varied, which is defined in the claims that
follow.
