Description

The present invention is based on an electrical/electronic installation device designed according to the preamble of the main claim.

Such electrical/electronic installation devices are generally intended to influence a large number of electrical actuators installed in buildings (blind drives, lighting devices, ventilation systems, heating systems and so on) as required. For this purpose, a wide variety of installation devices such as switches, buttons, dimmers, controllers (room temperature controllers) and so on have become known. For influencing, operating variables are usually set by the user on the operating elements, which are transmitted to the associated actuators in order to influence them. The transmission can be wired or wireless, for example by radio. Electrical/electronic installation devices, which are designed as so-called rotary switches or rotary controls, often have an adjustment knob on the user side, which is rotatably mounted on a shaft. The functional device that is present in the functional module and that can be rotated is often designed, for example, as a potentiometer, incremental transmitter, and so on.

through the DE 80 28 507 U1 an adjusting knob for an electrical/electronic installation device corresponding to the preamble of the main claim has become known. As is generally known, this electrical/electronic installation device has a functional module provided for receiving the electrical/electronic functional components and a design cover which can be fixed to the functional module and to which the adjustment knob is assigned by the user. The adjustment knob is intended to influence a functional device located in the functional module via a shaft by means of a rotary actuation, which is intended to control at least one actuator connected to the functional module, with the rotation limitation of the Adjustment knob stop elements are provided, which are located on a first and a second adjustment ring, the adjustment rings each having at least one toothed segment for fine-grained secured adjustment and are each mounted rotatably by 360 degrees. The two adjustment rings are located on the underside of the adjustment knob and are comparatively filigree, which is why they can often only be operated using a tool. Adjustment options with regard to a so-called wallpaper compensation are also not possible or only possible to a very limited extent with such an embodiment.

In addition, through the DE 10 2019 108 680 B3 an electrical/electronic installation device has become known, in which control variables can be set by means of a rotary adjustment knob, and which has a sensor element which is arranged outside the housing of the function module, namely on the upper side of the support plate. The sensor element is therefore arranged between the top of the support plate and the underside of the design cover.

Further revealed GB 2 546 124 A an electrical/electronic installation device according to the preamble of claim 1.

Based on electrical/electronic installation devices designed in this way, the object of the present invention is to create an electrical/electronic installation device in which the adjustment rings are arranged and designed in such a way that the user can easily adjust or adjust the rotation limitation of the adjustment knob without tools results.

According to the invention, this object is achieved by the features specified in the main claim.

With such a design, it is particularly advantageous that the design and arrangement of the adjusting rings to a greater extent also enables so-called wallpaper compensation and the user can visually see more clearly which values have been set for the rotation limitation of the setting knob.

As can be seen from the drawings, such an electrical/electronic installation device has a functional module 1 provided for accommodating the electrical/electronic functional components, a design cover 2 being fixed to the functional module 1 . The design cover 2 is assigned an adjusting knob 3 by the user, which is provided for influencing a functional device located in the functional module 1 via a shaft 4 by means of a rotary actuation - not shown for the sake of simplicity. The functional device is in turn provided for influencing at least one actuator connected to the functional module 1 as required. For this purpose, a rotation limitation is provided for the adjustment knob 3 via first stop elements 5 and second stop elements 6, which are located on a first adjustment ring 7 and a second adjustment ring 8, the two adjustment rings 7, 8 for finely divided secured adjustment have a first toothed segment 9 and a second toothed segment 10 and are each mounted rotatably by 360 degrees.

As can also be seen from the figures, the design cover 2 has a receiving recess 11 for receiving the adjusting knob 3 . The receiving trough 11 is provided in one piece with a toothed rim 12 toothed on both sides (internal toothing, external toothing), to which the first adjusting ring 7 is assigned on the outside and the second adjusting ring 8 on the inside so that it can rotate. The two adjusting rings 7 , 8 each engage with a toothed segment 9 , 10 in the associated toothing of the ring gear 12 . The two toothed segments 9,10 each have several, for example four, teeth.

As in particular from the figures 1 and 2 shows, there is the design cover 2 according to the first embodiment of a cover frame A and a center piece Z, so the design cover 2 is constructed in two parts. The receiving trough 11 with the ring gear 12 is located in one piece on the central piece Z.

As in particular from the Figures 3 and 4 shows, the design cover 2 according to the second embodiment is made in one piece. The design cover is designed in the form of a hood, which provides the receiving trough 11 with the ring gear 12 in one piece.

The following technical explanations apply to both exemplary embodiments shown in the figures. As already mentioned, the ring gear 12 is toothed on both sides, that is, on its outer annular surface and on its inner annular surface. Both the teeth of the ring gear 12 located on the outer ring surface and the teeth of the ring gear 12 located on the inner ring surface have a weakened (rounding off) sawtooth-like shape. As already mentioned, both the first adjusting ring 7 and the second adjusting ring 8 each have a toothed segment 9, 10, with the teeth of the two toothed segments 9,10 also having a weakened one (Rounding) have a sawtooth shape. The shape of the teeth of the two adjusting rings 7.8 and the sprocket 12 ensures that the two adjusting rings 7.8 can only be easily adjusted in the direction specified thereby, ie either only slightly clockwise or only slightly counterclockwise. A sawtooth shape means that each tooth has a steep and a flat tooth flank.

As can also be seen from the figures, the first adjustment ring 7 and the second adjustment ring 8 have first guide elements 13, which each engage with a corresponding groove (first guide elements 13) in the ring gear 12 (not shown for the sake of simplicity). One groove each is located in the outer annular surface and the inner annular surface of the ring gear 12. In addition, the design cover 2 has second guide elements 14, which are hook-shaped and are operatively connected to the edge area of the first adjustment ring 7. By means of the first guide elements 13 and the second guide elements 14, both a captive holder and a particularly good, rotatable bearing for the two adjustment rings 7, 8 are realized in a simple manner.

As already mentioned, there is a first stop element 5 in one piece on the first adjusting ring 7 and a second stop element 6 on the second adjusting ring 8. The two stop elements 5, 6 are intended to interact with a first stop lug 15 and a second stop lug 16, which are formed on the underside of the adjusting knob 3 assigned to the design cover 2 . Thus, in a particularly simple manner, it is possible to set a rotation limitation for the adjustment knob 3 as required. With such an embodiment, it is therefore possible in a particularly simple manner to specify an exact limitation of the operating variables that can be set by the user.

In the present embodiment, the electrical / electronic installation device is designed as a so-called room temperature controller, which is why the functional module 1 with at least one for detecting environmental variables provided sensor device is equipped. In the present case, the sensor device has a sensor element 17 which is arranged outside the housing of the functional module 1 . The sensor element 17 is provided for determining the room temperature. The determined room temperature, in conjunction with the operating variable set by the user via the adjusting knob 3, is used to influence the actuator.

The function module 1 is intended for installation in an installation box and is equipped with a support plate 19 . The shaft 4 provided for transmitting the rotary actuation of the adjustment knob 3 is mounted on the one hand within the functional module 1 and on the other hand is provided for attaching the adjustment knob 3 in a secure position. The adjusting knob 3 therefore has a correspondingly designed coupling pin 18 in one piece on its underside facing the design cover 2 . As already mentioned, the shaft 4 provided for transmitting the rotary actuation of the adjustment knob 3 is mounted within the functional module 1 on the one hand and is also provided on the one hand for coupling a functional device designed as a potentiometer (not shown for the sake of simplicity). The potentiometer has a corresponding design for generating a latching adjustment haptic.

An electrical/electronic installation device is thus created, in which the two adjustment rings 7, 8 are arranged and designed in such a way that the user can easily adjust or set the rotation limitation of the adjustment knob 3 without tools. Advantageously, the design and arrangement of the two adjusting rings 7, 8 described above also allow a so-called wallpaper compensation to a greater extent. In addition, the user can clearly see which values have been set for the rotation limitation of the adjustment knob 3 .
