Description

installation device

The present invention relates to an electrical installation device with a rocker switch for actuating a switching device comprising at least three switching elements.

Such installation devices are basically known, but suffer from the disadvantage that it may undesirably come to a multiple operation of individual switching elements or to a simultaneous actuation of various switching elements when actuated. In addition, the functionality is often fixed in known electrical installation devices, so that a switching element is assigned only a single, predefined switching function.

It is the object of the present invention, an electrical installation device of the type mentioned in such a way that an increased switching safety is given and for the user a simplified and reliable operability is created.

The solution of this object is achieved by the features of claim 1 and in particular in that the at least three switching elements of the actuating rocker are actuated individually, wherein the rocker arm is mounted gimbal and about a first axis relative to a coupling element is pivotable, which in turn to a second , is pivotable relative to the installation housing to the first right-angled axis. In addition, each switching element is assigned a light source with which light can be emitted through the actuating rocker. With the installation device according to the invention, it is first ensured that other switching elements are not accidentally actuated upon actuation of a switching element, as is ensured by the gimbal storage of the rocker switch on the coupling element that only the operator-operated area of the rocker switch in the direction of the associated switching element moves, at the same time move the remaining areas of the rocker switch from the associated switching elements away. At the same time, the cardanic mounting of the actuating rocker ensures that, in the case of a central application of force to the rocker switch, none of the shifting elements is actuated.

Since each switching element is assigned its own light source, with which light can be emitted through the actuating rocker, not only the function of the respective switching element can be visualized, for example by means of symbols or templates. Rather, it is also possible to visualize the operation of the switching element itself by the light source, for example, by this radiates brighter during the actual operation than in a resting state. The electrical installation device can be programmed individually, so that the individual switching elements are assigned a wide variety of switching functions, with a visualization of the switching functions can be carried out by the different light sources, which are assigned to the individual switching elements. By inserting a template or foil in the rocker switch, the set or desired switching functions can be visualized, wherein the desired switching function can be changed or adjusted at any time.

Advantageous embodiments of the invention are described in the description, the drawings and the subclaims. According to a first advantageous embodiment, the actuating rocker can have two diagonals in plan view, wherein each switching element is arranged on a perpendicular to a diagonal. In other words, each switching element is in a plane that is perpendicular to the rocker and in which the diagonal is located. In this way, a symmetrical arrangement is provided, in particular when the position of the switching elements from the center of the actuating rocker is equidistant, and by selecting the largest possible distance to the center of the rocker a maximum lever arm can be created, the tactile feeling for a Optimized operator.

According to a further advantageous embodiment, each light source can be arranged on a perpendicular to a diagonal, whereby a good association of light source is ensured to switching element. It may be advantageous if the switching element from the center of the rocker is further away than the associated lighting means, since in this case the switching element can be arranged as far outside on the diagonal as possible in order to optimize the tactile feel of the shift.

To actuate the individual switching elements may be provided for each switching element, an actuating element which extends through the coupling element and which is integrally connected, for example, with the actuating rocker. Alternatively, it is possible to provide an actuating element for each switching element, which is integrally connected to the coupling element. In this case, according to a further advantageous embodiment, an actuating element can be cut free for each switching element in the coupling element. This means that only a single component has to be manufactured during production, namely the coupling element, which already contains the actuating elements as integrally connected and cut-free elements. According to a further advantageous embodiment, each illuminant may be associated with an in particular conically widening screen. With such a screen, it is possible on the one hand to shield the light emitted by a light source, so that no stray light falls on adjacent areas. On the other hand, the radiated light can be focused and reflected with the aid of the screen so that it only impinges on a desired section of the actuating rocker.

According to a further advantageous embodiment, an actuating element for actuating the associated switching element can be provided on the screen, so that a pressure is exerted on the actuating screen by means of pressure on the screen lying behind the actuating rocker and this force with the aid of the screen provided on the actuating element is transferred to the switching element.

According to a further advantageous embodiment, spring elements can be formed on the coupling element, which return the coupling element after pivoting in its rest position. Such spring elements can be formed, for example in the form of molded webs, which are bent elastically upon pivoting of the coupling element and thereby exert a restoring force on the coupling element to return this in a rest position.

According to a further advantageous embodiment spring elements can be formed on the coupling element, which guide the actuating rocker back to its rest position after pivoting. In this way, it is ensured that the actuating rocker is always returned to its rest position when no force is exerted on them. According to a further advantageous embodiment, the spring elements may be formed by the screens, so that they exert a dual function, namely serving as an optical screen and on the one hand on the other hand as a spring element for re-dividing the actuating rocker. If the actuators for actuating the switching elements are also formed on the umbrellas, the umbrellas have a triple function, since they serve not only optical purposes but also mechanical resetting and mechanical actuation.

According to a further advantageous embodiment, a spacer may be provided in the center of the actuating rocker and / or in the center of the coupling element, which supports a central region of the actuating rocker and / or the coupling element against a housing-fixed component. This measure can serve to additionally support the actuating rocker against a force exerted on its central region in order to prevent undesired operation of shifting elements. It is true that movement of the actuating rocker by applying force to its central region per se is already largely prevented by the planned Karanian bearing arrangement. Due to tolerances and by the elasticity of parts, however, a movement of the actuating rocker may still be possible by applying force to its central region under appropriate external forces, which is prevented by a spacer provided in the central region.

According to a further advantageous embodiment, a deflectable from the outside spring arm can be cut free on the housing, with which a arranged in the housing housing button is actuated. As a result, for example, a back portion of the electronics provided in the installation housing can be made in a simple manner, without a tool having to be introduced into the interior of the housing. It is also possible to use the spring arm for actuating a sabotage contact, which is then closed by means of the spring arm, for example, when the installation housing is properly installed in a receptacle. Hereinafter, the present invention will be described purely by way of example with reference to an advantageous embodiment and with reference to the accompanying drawings. 1 shows an exploded view of an electrical installation device;

Fig. 1;

Fig. 4 is a sectional view taken along the line A-A of Fig. 3; and FIG. 5 is a sectional view taken along the line B-B of FIG. 3.

Fig. 1 shows an exploded view of an electrical installation device comprising a mounting housing 10 in which a control board 12 and a circuit board 14 are arranged. For actuating switching elements arranged on the circuit board 14, an actuating rocker 20 is provided, which is mounted on the installation housing 10 via a coupling element 16. Between the actuating rocker 20 and coupling element 16, a template 18 can be inserted.

The installation housing is formed in the illustrated embodiment as a flush-mounted housing, which is provided on its rear side with two metal brackets 22a and 22b to lock the installation device in the flush-mounted housing. According to an alternative embodiment, however, the installation housing 10 may be formed as a surface-mounted housing. As illustrated particularly in FIGS. 1 and 5, the control board 12 is fastened in the housing 10 by means of two spring clips 24a and 24b cut free in the peripheral wall of the installation housing 10, which spring back outward when the control board 12 is pushed in and then into its housing. return to the initial position after the control board 12 rests on formed on the inside of the mounting housing 10 stops 26a and 26b.

As illustrated in particular in FIGS. 2 and 3, an externally deflectable spring arm 28 is cut free on the rear side of the installation housing 10 and has a cup-shaped recess 30 into which a tool or pin can be inserted in order to deflect the spring arm 28 to actuate a micro-switch 32 arranged in the installation housing 10 on the rear side of the control board 12. In this way, a provision of provided on the control board control electronics can be made or it can be checked whether the mounting housing 10 is properly secured in a receptacle.

Incidentally, various electronic components and processors are provided on the control board 12, which enable a coupling of the electrical installation device to a bus system. On the back of the control board 12 has these two pins 34 (in Fig. 1, only one pin is visible), which extend through the mounting housing 10 on the back to the outside (see Fig. 3) and a connection of a plug-in element to Power supply and allow for data transmission. For this purpose, the installation housing 10 is provided on the back with a receiving opening 35 into which the plug-in element can be inserted in order to contact the connection pins 34.

In addition, a receptacle 36 (see Fig. 5) is arranged on the control board 12, in the contact pins of a plug 38 can be used, which is located on the back of the circuit board 14. The circuit board 14 is inserted into an integrally formed on the front of the mounting housing 10 frame-like opening, which is surrounded by an integrally formed on the front of the mounting housing 10 frame 40, wherein the contact pins of the plug 38 are inserted into the receptacle 36 of the control board 12 and thereby at Inserting the circuit board 14 in the mounting housing 10 make an electrical connection between the two boards.

As illustrated in FIG. 1, the square circuit board 14 has a larger area than the control board 12 and on the front side of the circuit board 14 at the outermost corners of a total of four switching elements 42 are provided in the form of micro-scanners. The four switching elements 42 are part of a switching device that can initiate switching functions by means of the provided on the control board 12 control electronics, which can be assigned to the individual switching elements 42 arbitrarily.

In order to enable a single single operation of each individual switching element with the actuating rocker 20, it is cardanically mounted via the coupling element 16 and can be pivoted about a first axis X relative to the coupling element 16. For this purpose, the actuating rocker 20 is provided at its rear with two pivot pins 44 which engage in corresponding receptacles on the coupling element 60, so that the actuating rocker 20 is pivotable relative to the coupling element 16 about the axis X. The coupling element 16 itself is pivotable about a second pivot axis Y, which is perpendicular to the first pivot axis X and that relative to the mounting housing 20. For this purpose, the mounting housing 20 in the region of the frame 40 has an upper and a lower pivot receptacle 46, in the two engage on the coupling element integrally formed pivot pin 48, so that the coupling element 16 is pivotable about the axis Y relative to the installation housing 10. As further illustrated in FIG. 1, each switching element 42 on the circuit board 14 is assigned a luminous means 50, with which light can be emitted through the coupling element 16, the template 18 and the actuating rocker 20 to the front of the installation device. For this purpose, the actuating rocker 20 may be transparent, translucent or provided with openings.

1, the actuating rocker 20 is square in the illustrated embodiment and has two diagonals, wherein each switching element 42 as well as each luminous means 50 is arranged so that it is on a perpendicular to a diagonal. In this case, the switching elements 42 are arranged as far as possible on the outside of the circuit board 14, so that each switching element 42 from the center of the actuating rocker 20 is further away than the associated lamp 50, which is adjacent to each

Switching element 42 is located.

In order to shield and reflect the light emitted by the light sources 50, conically widening screens 52 are integrally formed on the coupling element 16 (a total of six in the illustrated embodiment). These umbrellas lie in the assembled state with their front side on the rear side of the actuating rocker 20 (see Fig. 2) and are cut free in the coupling element 16 and only connected via a resilient web 54 with the main body of the coupling element 16. In a deflection of the actuating rocker 20 about the axis X, the spring bars 54 exert a force on the actuating rocker 20, so that it returns to its rest position when no force is exerted by an operator on the rocker switch.

At the back of the four outer screens 52 (the two central screens is not assigned a switching element) is formed in each case an actuating element in the form of a small web 60 (see Fig .. 1 and 2), wherein the web 60 on the rear it befindlichem switching element 42 presses when a force is applied to the corresponding sector of the actuating rocker 20.

For a provision of the coupling element 16 in its rest position 16 resilient webs 62 are integrally formed on the top and on the underside of the coupling element, which rest with their free ends on projections 64 which are integrally formed on the outside of the frame 40.

In order to prevent undesired actuation of a switching element 42 in the case of a force exerted centrally on the actuating rocker 20, the coupling element 16 is provided at its center with a molded spacer 66 (cf. State housing fixed circuit board 14 rests and thereby supports a central region of the rocker actuator 20 and the coupling element 16.

Finally, a transmitter 68 and a receiver 70 are provided on the front side of the circuit board 14 (see FIGS. 1 and 5), by means of which the control electronics can recognize whether a user is approaching the installation device in order to activate it or in a wakeful state, for example, by activating the lighting means 50 to indicate to the user which control functions are given. In order to allow the passage of (non-visible) radiation from the transmitter 68 to the receiver 70, the coupling element 16 approximately in alignment with the pivot axis X has two passage openings 72 and 74 with which corresponding openings in the template 18 are aligned. At the rear of the actuating element 60, two annular webs 76, 78 (cf., Fig. 5) are integrally formed in the region of the openings of the template 18, which allow a centering of the template 18.

When approaching by the user in the above-described installation device, it is registered by the receiver 70, who is the one who received by the transmitter 68 emitted radiation, which has been reflected by a user. Subsequently, the controller can put the installation device in a standby state, for example, by the lighting means 50 are activated. When subsequently pressed, for example, on the upper left quadrant of the actuating rocker 20, this pivots both about the pivot axis X relative to the coupling element 16 and the coupling element 16 pivoted about the pivot axis Y relative to the mounting housing 10, so that on the screen 52 of the associated Illuminant 50 molded actuator 60 presses the switching element 42 and triggers a switching command. By the restoring force of the left upper spring element 62 and by the restoring force of the spring bars 54, the actuating rocker 20 is then moved back to its rest position when the user no longer touches the actuating rocker 20. For the remaining three quadrants the above-described operation applies mutatis mutandis in the same way.

It should be noted that the two central bulbs each switching element is not assigned, that is, these bulbs can be used for any function or status indicators.
