Description

Improvements introduced in the mechanisms built-in rocker switch, for operating systems Low voltage electrical.

The present invention patent consists of improvements introduced in the key mechanisms tilting, arranged generally embedded, and used to the operation of low voltage electrical installations, preferably domestic or commercial, and whose peculiarities Essentials are described below.

Until now the mechanisms for command and drive of this type of electrical installations at low tension, allowed the rapid exchange of parts between different mechanisms, intended for diverse applications, although it was necessary to change several components to be able to act, for example, as a switch or as a crossover switch. This example farragoso is described in the Spanish Utility Model U283400 (6). Also its components had to be varied in the case of having to use and attach different models of frames, as described Spanish Utility Model U 9800176 (0) which is not practical and also expensive.

The Spanish Invention Patent No. P200101354, presented an improvement in the possibility of exchange of components, according to the specific application of the mechanism of command, but it is also an expensive and difficult procedure implementation, as has been verified.

It is one of the requirements, at present, attending to the practical and economic imposition of offering elements modular for any type of electrical installations, achieve that the electrical mechanisms for actuation and control present a series of common elements that can be exchanged quickly and easily, which can eliminate one of the biggest drawbacks of existing mechanisms nowadays. This will allow, immediately and easily, adapt these mechanisms to various electrical installations type, without having to proceed to change all of the components, by replacing any of them, or well with the incorporation of other complementary.

Finally, thanks to the improvements that are described, in the variants provided with light signaling, the rational use of such will be greatly facilitated devices.

Everything previously stated will obviously have an impact on processing costs, since it will be necessary, manufacture only a few and certain components, the remaining ones being valid for the different types of mechanism of control, also affecting the costs of stock storage and forecasting, for the same reasons, as well as in the installation and maintenance work, and in those of replacement of components by changing the command function to perform.

Reference is made, in the description, which follows the improvements object of the present invention according with what has been represented in the figures that accompany this memory, in which various practical applications of the aforementioned improvements. In these figures, references identical designate similar elements.

According to the aforementioned drawings, the rocker mechanisms for operating installations low voltage electric, and that will be embedded, to those who have applied the refinements objects of the present invention, they consist essentially of presenting a rocker key (1), which it is placed on a perimeter frame (2) of contours preferably rounded, which is perfectly and conveniently coupled in a socket (3), also with smoothly rounded contours and held, in turn, on the metal anchoring support (4) by the action of lateral flanges (5) acting under pressure, whose support is provided with side holes (4a) for its subject to the place where the mechanism will be embedded.

Below the mentioned metal support (4) the main body of the mechanism is located, in its realization (6) to apply it to the function of switch, push button and switch, as shown in Figure 11, and in its embodiment (7) to apply it to the double switch and double function switch, according to figure 12.

On the mentioned main body (6) is located the rocker (8), on which the single key (1) will rock, while on the main body (7), for double switch and double switch, the double rocker (9) and (9a) is located on which the two halves (1a) and (1b) of the key will tilt double. The double rocker arm is joined by the pin shaft (9b).

The mechanism is completed, with the spring vertical helical (10) that facilitates the return of the rocker (8) to its initial position when operated on the key (1), spring that it will be double (10) and (10a) in the application of the rocker (9) and (9a). This spring rests on the U-shaped impeller (11) which, at its  once, it will rest on the transverse contact (12) located between the lateral contacts (13) and (13a). The contacts of emborne follow (14) and (14a), in the embodiment as a switch, and duplicates all of them in the realization of double switch, according to see in figure 3, or the lateral contacts (15) (16) and (17), the three terminal contacts (18), and the contact (19), in the embodiment for switch, according to figure 4, as well as all of them  duplicates in the embodiment of figure 5 as double switch.

The realization as a push-button switch, according to Figure 2 will also be provided with the horizontal spring (20) that causes the immediate return of the rocker to its position initial, in that push-button function, when the key (1).

In the embodiments for application such as double switch or switch, according to figures 3 and 5, the key drive is double (1a) and (1b), separated and installed a next to each other. Figure 15, to facilitate understanding, shows only one of said half keys, installed in the frame (two).

The main body of the unit mechanism (6) it has in the upper outer part of its back side, the tabs (27a), symmetrically arranged and whose purpose is offer greater support on the metal anchor support (4), eliminating coupling difficulties that may arise in the case of unevenness in the recessed box where the mechanism will be installed.

The tabs (27b) located in the upper part of the side of the body for double mechanism (7) have identical purpose

In the embodiments in which the mechanism is equipped with a pilot or a luminous, as represented by the Figures 6 to 10, the key (1c) is provided with a slot longitudinal (21) with the transparent or translucent cover (22), fixed in pressure in said groove, and through which the neon light (23), located under the key, will be visible in the support (24), provided with the necessary contacts (25), necessary for the correct electrical connection of said support (24).

The main body, both for mechanism unit (6) as for double mechanism (7), it has supports lateral (26) where the rocker will rest and be able to swing, single (8) or double (9), depending on the case.

The ends of the mentioned bodies main (6) and (7), are provided with keys (27), such as shows Figures 11 and 12, by means of which the fast embossing system drive.

Inside the main body will remain located, and conveniently fixed, the contacts that will allow the correct functioning of the mechanism in its various applications, as described above.

Also, in its lower part, the body main is provided with inlet holes (28) of the electrical conductors (29) that must be plugged into the device.

The socket (3) snaps onto the frame (2), thanks to the lateral projection (30) that the frame has and that penetrates into the side opening (31) that the socket (3) on its inner edge, corresponding all Highlights (30) with the respective openings (31). As he coupling as the socket release is possible due to the elasticity of the material itself, on the shoulder (30).

Figures 19 to 22 show the arrangement of the projections (30) and openings (31) in the corners of the frames. In the case of embodiments with more than one mechanism, it is say, with more than one frame, (2a) and with a double socket (3a), when there are two mechanisms (figure 21), or triple socket (3b) (figure 22), when there are three mechanisms, the projections and openings are likewise matching. In these variants, the frames (2a) have, in their external faces, own collateral support elements ones with other, consistent, as seen in figure 23 mainly, in a cylindrical projection (32) that is introduced, of plug-in sliding form, in the hollow boss (33) corresponding to the adjacent, outgoing frame whose hollow is cylindrical and coincident with the cylindrical projection (32).

The essential characteristics of refinements object of the present invention patent, do that, in order to minimize the variety of components of the mechanism described, the framework (2), described at  principle according to figure 1, is identical to the frames (2 a) that are join, overlapping, for the realization of multiple mechanisms, according to figures 19, 21 and 22.

For its part, the metal support (4), in shape flat quadrangular frame, in addition to having the holes for its placement and fixing has, on two of its opposite sides, some substantially vertical emerging tabs (5) that will allow such as shown in figures 24 and 25, the clamping and coupling of the mentioned frame (2).

The different elements described, and that make up the mechanism to which the improvements have been applied object of the present invention, configure the various applications of the mentioned mechanism.

In the switch arrangement, with only one key, according to figure 26, the key (1) is resting on the rocker arm (8), tilting on the upper supports (26) of the body (6).

The key (1) presents in two of its sides facing tabs (34), as seen in the Figures 13, 14, 26 and 32, which are located inside of the corresponding openings that the frame (2) has in its corresponding sides, thereby avoiding its detachment accidental, including some projections (36), arranged in the lower face of the key (1), which allow correct support and fixation on the rocker (8).

The mentioned key (1) also has, in its two other side edges, the tabs (35) (see figures 13 and 14), which constitute the damping stop of the key when falling to one side or the other, in its rocking motion, such as It can be seen in figure 31.

The special structure of these tabs (35), equipped inside, with a tongue (35a) confer a certain elasticity to the whole, especially in the fall of the key (1) which is synchronized by the damping action of  said tab (35a).

In the case of the middle (1a) or (1b) key, the Figure 14 shows the arrangement of the side flange (34), that of the highlight (37) for your support on the double rocker (9) and that of the damping tabs (35) with their tabs (35a).

The cylindrical spring (10), located in the inside the rocker (8) and next to the `` U '' support (11), it rests on the transverse contact (12), which balances and allows to establish the appropriate contact, with the lateral contacts (13) and (13a), as depicted in Figure 33.

The larger scale detail of figure 34 draws the entrance area (28) of the electric conductor (29) that will be embossed by the elastic action of the contact (14), and the wall of the contact (13). On the outside of the body (6) is the key (38), which is the one used to disconnect the conductor or electric cable (29). In the event that this conductor is thread rigid, is arranged under pressure, held by the aforementioned spring (14). To undo it, act on the key (38), which makes reverse the contact (14), leaving the conductor (29) free. In the If this conductor (29) is flexible wire, when introduced the button (38) must be operated and when released, the driver remains locked, repeating said operation, the driver (29) is will release

The key (38) always acts through the opening (39) that the body (6) has on its side face correspondent.

The referred spring-contact elastic or flexible (14) is folded in the form of `` J '', with its bottom formed by two identical pins (14a) that can fold separately, which facilitates embedding at will.

This body (6) also has, in its perimeter upper, a warped flange (40) that rests on the contour inside (4b) of the metal support (4), while the side opposite has a tab (41) that locks under the mentioned interior contour (4b). These characteristics are appreciated with clarity in the details drawn in figures 37 and 38.

The neon lamp (23) is the one that provides the luminosity that will be visible through the longitudinal groove (21) with the transparent or translucent cover (22) that has the key (1c), characterized in that it will be of the `` luminous '' type or `` pilot '' type, as required in the installation.

The mentioned neon (23) is housed in the inside the support (24) and protected by the flip cover (24a) which is provided with a hole (24b) where the light will be visible issued by said neon (23). A series of contacts (25) are will have in certain accommodations (42), located in each of the four vertices of the support itself. These contacts will remain embedded on the circuit arranged in the body (6) of the inside the mechanism, under the key (1c), the type being different circuit according to the function that the element should play Luminous mentioned.

The circuit drawn in figure 44 has the contacts in the accommodation on the same side (42), that is, a front corner and in another rear corner of the support (24), thus establishing the circuit with the neon (23). This application It is for unipolar switch or push button as `` luminous '' and for switch as `` pilot '', shown represented schematically also in figures 47, 48 and 51.

The circuit shown in Figure 45, It has its contacts in the housings (42) of both corners front of the support (24) and is used for the application of `` pilot '' for unipolar switch. The circuit is schematically represented in figure 49.

The circuit drawn in Figure 46 has the contacts in the two rear corners of the support (24), being The `` luminous '' switch application, as complete the scheme of figure 50.

When the support (24) with its corresponding Neon lamp (23) is fixed on the body (6), acting as switch, said lamp is on when the switch does not allows the passage of the current, facilitating the visualization of the push button (1c). If, on the contrary, the support (24), together with its neon lamp (23) it is installed for the function of the mechanism As a switch, the lamp turns on when it is in position of connected.

As you can see, the improvements of the invention advantageously allow to achieve that the electrical mechanisms present a few elements commons that can be easily exchanged, and adopt them to electrical installations of different types, without having to change all components, being able therefore to replace some of them or incorporate other complementary.

Described sufficiently the object of the present invention, it should be noted that at the time of realization practice may vary shapes, dimensions, as well as materials used, in the different components of the mechanism to which the improvements described above have been applied, without altering or modifying its essentiality.
