Abstract

Description

Mounting device

Technical Field

The invention relates to an electrical installation device having an insertion housing, on which an operating rocker is arranged for operating a switching device, which switching device comprises a plurality of switching elements that can be actuated individually by the operating rocker, wherein a lighting device is associated with each switching element.

Background

Such a mounting device is known per se, for example from german patent document DE10233331C 1. But has the disadvantage that it may undesirably lead to multiple operations of a single switching element or simultaneous operations of different switching elements when operated. In addition, in the known electrical installation devices, the function is usually determined such that only one single predetermined switching function is assigned to a switching element.

Disclosure of Invention

The problem addressed by the invention is, in particular, to improve an electrical installation device of the type mentioned in the introduction in such a way that a higher switching safety is achieved and a simplified and reliable operability is provided for the user.

The object is achieved by an electrical installation device having a built-in housing on which an operating rocker is arranged for operating a switching device, which switching device comprises at least three switching elements that can be actuated individually by the operating rocker, wherein a lighting device is associated with each switching element, according to the invention the operating rocker is mounted in a cardanic manner and can be pivoted about a first axis relative to a coupling element, which can be pivoted about a second axis running at right angles to the first axis relative to the built-in housing, and light can be emitted through the operating rocker by means of the lighting device.

With the mounting device according to the invention, it is firstly ensured that when one switching element is actuated, the other switching elements are not actuated accidentally, since the actuating rocker is mounted via the coupling element in a cardanic manner, since it is ensured that only the region of the actuating rocker actuated by the operator is moved in the direction of the associated switching element, while the remaining region of the actuating rocker is moved away from the corresponding switching element. At the same time, the cardanic support of the operating rocker ensures that none of the switching elements is operated in the event of a force being applied to the center of the operating rocker.

Since each switching element is assigned an own lighting device, by means of which light can be emitted through the operating rocker, not only can the function of the switching elements be visualized, for example, by means of symbols or templates. The operation of the switching element itself can also be visualized by means of the lighting device, for example, by means of which a brighter light is emitted during actual operation than in the stationary state.

The electrical installation device can be individually programmed in order to assign different switching functions to the individual switching elements, wherein the visualization of the switching functions can be achieved by means of different lighting devices assigned to the individual switching elements. By placing the template or membrane into the operating seesaw, the set or desired switching function can be visualized, so that the required switching function can be modified or adjusted at any time.

Advantageous embodiments of the invention are described in the description and the drawings.

According to a first advantageous embodiment, the actuating rocker has two diagonal lines in plan view, and each switching element is arranged perpendicular to the diagonal lines. In other words, each switching element is in a plane perpendicular to the operating seesaw and in which the diagonal lies. In this way a symmetrical layout is provided, in particular when the switching elements are positioned equidistant from the center of the operating rocker, wherein by selecting the largest possible distance to the center of the operating rocker, the largest possible lever arm can be created, which optimizes the tactile sensation of the operator.

According to a further advantageous embodiment, each lighting device is arranged on a perpendicular to the diagonal, thereby ensuring a good assignment of the lighting devices with respect to the switching elements. It may be advantageous if the switching element is located at a greater distance from the center of the operating rocker than the correspondingly associated lighting device, since in this case the switching element can be arranged as far as possible outside the diagonal in order to optimize the tactile switching sensation.

For actuating the individual switching elements, an actuating element can be provided for each switching element, which actuating element extends through the coupling element and is connected integrally, for example, with the actuating rocker. In addition, an actuating element can be provided for each switching element, which actuating element is connected integrally to the coupling element. In this case, according to a further advantageous embodiment, the actuating element is cut freely into the coupling element for each switching element. This means that only one single component, i.e. the coupling element, which already contains the operating element as an integral connecting and free cutting element, needs to be manufactured during the production process.

In a further advantageous embodiment, a screen, in particular a conically widening screen, is assigned to each illumination device. With such a screen, on the one hand, the light emitted by the illumination device can be shielded so that no scattered light falls on adjacent regions. On the other hand, the radiated light can be focused and reflected by means of the screen, so that it impinges only on the desired portion of the operating seesaw.

In a further advantageous embodiment, an actuating element for actuating the associated switching element is arranged on the screen, so that a force is exerted on the screen behind the actuating rocker by the pressure acting on the actuating rocker and is transmitted to the switching element by means of the actuating element arranged on the screen.

According to a further advantageous embodiment, a spring element can be formed on the coupling element, which spring element brings the coupling element back into its rest position after pivoting. Such a spring element can, for example, be designed as a profiled web which bends elastically when the coupling element is pivoted, so that a restoring force is exerted on the coupling element to return it to the rest position.

In a further advantageous embodiment, a spring element can be formed on the coupling element, which spring element returns the actuating rocker to its rest position after pivoting. In this way it is ensured that the operating seesaws always return to their rest position when no force is exerted on them. According to another advantageous embodiment, the elastic elements can be formed by the screens such that they serve the dual function of acting as an optical screen on the one hand and as an elastic element for resetting the operating seesaw on the other hand. If operating elements for operating the switching elements are also formed on the screen, the screen has a triple function, since they serve not only for optical purposes but also for mechanical resetting and mechanical operation.

In a further advantageous embodiment, a spacer is provided in the center of the actuating rocker and/or in the center of the coupling element, which spacer supports the central region of the actuating rocker and/or the central region of the coupling element on the component fixed to the housing. This measure can also be used to support the operating seesaw against forces additionally exerted on its central area in order to prevent undesired operation of the switching element. Although the movements of the operating seesaw caused by the application of force in its central region are largely prevented by the provision of the gimbal bearings. However, due to tolerances and the elasticity of the components, it is possible in some cases to move the operating seesaw under the action of a corresponding external force by applying a force to its central region, which is prevented by the spacer provided in the central region.

According to a further advantageous embodiment, an externally deflectable spring arm can be cut freely on the installation housing, by means of which spring arm a pushbutton arranged in the installation housing can be actuated. This makes it possible, for example, to reset the electronics arranged in the insert housing in a simple manner without having to introduce tools into the interior of the housing. It is also possible to use a spring arm to operate the breaking contact which is then closed, for example by the spring arm, for example when the flush-mounted housing is correctly mounted in the holder.

Detailed Description

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

In the embodiment shown, the flush-mounted housing is designed as a concealed housing which is provided with two

metal clips

22a and 22b on its rear side in order to lock the mounting device in the concealed housing. However, according to an alternative embodiment, the flush-mounted housing 10 can be designed as an outer housing.

As shown in particular in fig. 1 and 5, the control plate 12 is fixed in the housing 10 by means of two

spring clips

24a and 24b cut freely in the peripheral wall of the flush-mounted housing 10, the

spring clips

24a and 24b springing back outwards when the control plate 12 is inserted and then returning to their initial position after the control plate 12 rests on

stops

26a and 26b formed on the inside of the flush-mounted housing 10.

As shown in particular in fig. 2 and 3, the spring arm 28, which can be deflected from the outside, is cut free on the rear side of the insert housing 10, and has a cup-shaped recess 30 into which a tool or pin can be inserted in order to actuate a microswitch 32 arranged in the insert housing 10 on the rear side of the control plate 12 by deflection of the spring arm 28. In this way, the control electronics arranged on the control panel can be reset or can be checked whether the flush-mounted housing 10 is properly secured in the holder.

In addition, various electronic components and processors are provided on the control board 12, which enable the electrical installation device to be connected to the bus system. On the rear side of the control panel 12, there are two coupling pins 34 (only one pin is visible in fig. 1), which extend outward at the rear side through the flush-mounted housing 10 (see fig. 3) and allow the connection of plug elements for power supply and data transmission. For this purpose, the installation housing 10 is provided on the rear side with a mounting hole 35, into which mounting hole 35 a plug element can be inserted in order to contact the coupling pin 34.

Furthermore, a socket 36 (see fig. 5) is arranged on the control board 12, into which socket 36 contact pins of a plug 38 located on the rear side of the circuit board 14 can be inserted.

The circuit board 14 is inserted into a frame-like opening formed on the front side of the installation housing 10, which is surrounded by a frame 40 formed on the front side of the installation housing 10, wherein the contact pins of the plug 38 are inserted into the sockets 36 of the control board 12 and thereby establish an electrically conductive connection between the two boards when the circuit board 14 is inserted into the installation housing 10.

As shown in fig. 1, the square circuit board 14 has a larger area than the control board 12, and a total of four switching elements 42 in the form of microprobes are provided on the front side of the circuit board 14 at outermost corners thereof. The four switching elements 42 are components of a switching device which can be triggered by means of control electronics provided on the control board 12 to a switching function which can be assigned to each switching element 42 as desired.

In order to enable each switching element to be operated individually by means of the operating rocker 20, the operating rocker is mounted via the coupling element 16 in a manner articulated and pivotable about the first axis X relative to the coupling element 16. For this purpose, the actuating rocker 20 is provided on its rear side with two pivot pins 44, which pivot pins 44 engage in corresponding recesses on the coupling element 60, so that the actuating rocker 20 can be pivoted about the axis X relative to the coupling element 16.

The coupling element 16 is itself pivotable about a second pivot axis Y which extends at right angles to the first pivot axis X, specifically relative to the flush-mounted housing 20. For this purpose, the installation housing 20 has upper and lower pivot seats 46 in the region of the frame 40, into which pivot seats 46 two pivot pins 48 formed on the coupling element engage, so that the coupling element 16 can pivot about the axis Y relative to the installation housing 10.

As fig. 1 also shows, an illumination device 50 is associated with each switching element 42 on the circuit board 14, with which light can be emitted via the coupling element 16, the template 18 and the actuating rocker 20 to the front side of the mounting device. For this purpose, the operating seesaw 20 may be transparent, translucent or provided with a through hole.

As is shown in particular in fig. 1, the operating rocker 20 is square in the illustrated exemplary embodiment and has two diagonals, wherein each switching element 42 and each lighting device 50 are arranged such that they lie on a perpendicular to the diagonals. In this case, the switching elements 42 are arranged as far as possible on the outer side of the circuit board 14 such that each switching element 42 is further from the center of the operating seesaw 20 than the corresponding illumination device 50, the illumination device 50 being located beside each switching element 42.

In order to shield and reflect the light emitted by the illumination device 50, a (in the illustrated embodiment, a total of six) conically widening screen 52 is formed on the coupling element 16. These screens rest with their front side on the rear side of the operating rocker 20 in the assembled state (see fig. 2) and are cut free in the coupling element 16 and are connected to the body of the coupling element 16 only by the elastic web 54. Upon deflection of the operating seesaw 20 about the axis X, a force is exerted on the operating seesaw 20 by the resilient web 54, such that the resilient web 54 returns to its rest position when the operator is not exerting a force on the operating seesaw.

On the rear side of the four outer screens 52 (the two middle screens are not provided with switching elements), in each case one actuating element in the form of a small web 60 is formed (see fig. 1 and 2), wherein the web 60 bears on the switching element 42 located behind it when a force is applied to the corresponding sector of the actuating rocker.

In order to return the coupling element 16 to its rest position, elastic webs 62 are formed on the upper and lower sides of the coupling element, which rest with their free ends on projections 64 formed on the outside of the frame 40.

In order to prevent undesired actuation of the switching element 42 in the event of a force exerted centrally on the actuating rocker 20, the coupling element 16 is provided at its center with a shaped spacer 66 (see fig. 4 and 5) which rests against the circuit board 14 fixed in the mounted state on the housing and thus supports the actuating rocker 20 and the central region of the coupling element 16.

Finally, a transmitter 68 and a receiver 70 are provided on the front side of the circuit board 14 (see fig. 1 and 5), by means of which it can be recognized by the control electronics whether the user is approaching the installation device in order to activate it or is put into a wake-up state, for which purpose, for example, the lighting device 50 is activated in order to indicate to the user which control functions are present. To achieve transmission of (invisible) radiation from the emitter 68 to the receiver 70, the coupling element 16 has two through

holes

72 and 74 substantially aligned with the pivot axis X, with corresponding openings in the template 18 aligned with the through

holes

72 and 74. On the rear side of the actuating element 60, two annular webs 76,78 (see fig. 5) are formed in the region of the opening of the die plate 18, which enable centering of the die plate 18.

If the installation device is approached by the user, this is registered by a receiver 70 which receives the radiation emitted by the transmitter 68, which is reflected by the user. Subsequently, the controller may put the installation device in a standby state, for which e.g. the lighting device 50 is activated. If subsequently pressed, for example, on the upper left quadrant of the operating rocker 20, it pivots about the pivot axis X relative to the coupling element 16 and the coupling element 16 pivots about the pivot axis Y relative to the installation housing 10, so that the operating element 60 formed on the screen 52 of the associated lighting device 50 presses on the switching element 42 and triggers a switching command. By means of the restoring force of the spring element 62 on the upper left and the restoring force of the spring web 54, the actuating seesaw 20 is then moved back into its rest position when the user no longer touches the actuating seesaw 20. The above operation is contrasted in the same manner for the remaining three quadrants.

It should be noted that the two central lighting devices are each not provided with a switching element, that is to say that these lighting devices can be used for any function or status indicator.
