Description

Housing having an assembly situated therein The present invention relates to a housing having an assembly situated therein, comprising at least one actuator, such as a potentiometer, a switch, an adjustment cam, an adjustment screw, or the like, and an actuating element for actuating the at least one actuator. Potentiometers, i.e., adjustable resistors, switches, or the like, are used in electronic circuits for adjustment purposes, these actuators typically being soldered on a so-called circuit board. Actuating elements are used for actuating the actuators, using which a change of the set positions can be caused. In the case of high-quality and therefore also comparatively costly actuators, they are designed so that their actuating elements are integrated in the overall design of the actuator itself. In addition, actuators are known which have a simple and cost-effective construction and which are equipped with an actuating element later. Purely mechanical actuators such as adjustment cams, adjustment screws, or the like are also known. Such actuators may also be provided in embodiments in which overloads may result in damage. The present invention is based on the object of disclosing a housing of the type according to the species, in which at least one cost-effective actuator is used and this actuator is provided with an actuating element integrated into the housing in such a way that mechanical strains upon actuation of the actuating element may be extensively kept away from the actuator. This object is achieved according to the invention in that the actuator is situated adjacent to an outer wall of the housing, and the actuating element is provided in the area of its front side facing toward the outer wall with a receptacle for an actuating tool, which is in the area of a cutout of the outer wall which delimits the actuating travel of the actuator.
2 The actuating element for the at least one actuator is thus situated between the actuator itself and an outer wall of the housing and can exclusively be actuated through a cutout in the housing wall using a suitable tool. Therefore, both in the case of an actuating element which can be actuated by rotating and also by displacement, the adjustment travel is delimited by the size of the cutout of the outer wall and, because an actuating tool presses against the outer edges of the cutout when the adjustment travel is completely exhausted, excess mechanical strain of the actuator itself is almost completely precluded, so that damage of the actuator is avoided even in the case of clumsy action during an adjustment procedure. A refinement of the invention provides that catches are provided situated in the surrounding area of the cutout on the interior of the outer wall, in which catch projections attached on the actuating element engage. A locking setting of the actuator can thus be performed in a simple way, the number of the catch steps being conceivable according to the design of the relevant surrounding area of the cutout and/or by attaching a greater or lesser number of catch projections on the actuating element. It is particularly advantageous if the actuating element, at least in the area of its catch projections, and/or the outer wall in the area of its catches are implemented as springy. Because the springiness can be predefined by the design, the possibility exists of designing the ease or difficulty of movement of the individual possible catch positions according to the particular application. Further features of the invention are the subject matter of further subclaims. A preferred exemplary embodiment of the invention is shown in the appended drawings and is described in greater detail hereafter.
3 In the figures: Figure 1 shows a perspective partial illustration of a housing according to the invention Figure 2 shows an exploded illustration, enlarged in relation to Figure 1, of the housing in the direction of the arrow II in Figure 1 Figure 3 shows an enlarged partial illustration in the viewing direction according to Figure 1 Figure 4 shows an enlarged partial illustration of the housing in the viewing direction according to Figure 2 Figure 5 shows a schematically illustrated section through the housing in the area of an actuator and an actuating element for the actuator Figures 6a and 6b show various views of the actuating element Figure 7 shows a perspective illustration of the actuator. A housing is designated in each of Figures 1 through 4 by the reference numeral 1, in which - as shown in Figure 5 - an assembly 2 having at least one actuator 3 (only shown schematically) is situated. Overall, the assembly 2 comprises the at least one actuator 3 already noted and a circuit board 4, for example. In the concrete case, the actuator 3 is a potentiometer, which is adjustable by turning an actuating element 5.
4 Furthermore, as is clearly shown in Figure 5, the actuator 3 is situated adjacent to an outer wall 6 of the housing 1. The actuating element 5 is equipped with an actuating axis 7 having driver function and engages in the actuator 3. The actuating axis 7 passes through a through hole 8 of the circuit board 4. A shoulder 9 of the actuating element 5 is supported on the side of the circuit board 4 facing toward the outer wall 6. The actuating element 5 is equipped with a setting disc 10 on the front side facing directly toward the outer wall 6. This setting disc 10 presses against the interior of the outer wall 6 or on the base of the recess 11 inside the outer wall 6 and is radially supported in the edge area of this recess 11, so that radial forces engaging in this area may be absorbed. The distance between the circuit board 4 and the contact surface of the setting disc 10 on the outer wall 6 is selected so that a certain bias tension results between the setting disc 10 and the outer wall 6. As is clear from Figures 2 and 4, the base of the recess 11 is peripherally equipped with catches 12. The actuating element 5 is equipped on its front side of the setting disc 10 facing toward the outer wall 6 with catch projections 13, which engage in the catches 12 of the outer wall 6 depending on the rotational position of the actuating element 5. The outer wall 6 is provided with a sector-like cutout 14 in the exemplary embodiment shown. The setting disc 10 is provided with a receptacle 15 for an actuating tool (not shown), this receptacle 15 being in the area of the cutout 14 of the outer wall 6. This is very clearly recognizable from Figure 3 in particular. The setting disc 10 and/or the peripheral area of the cutout 14 of the outer wall 6 are implemented as springy in the direction of the actuating axis 7 of the actuating element 6.
5 This can be achieved in a simple way, for example, in that both the housing 1 and also the entire actuating element 5 are produced from a suitable plastic having corresponding spring properties. Because the setting disc 10, as already described above, presses against the surrounding area of the cutout 14 inside the outer wall 6 with a certain bias tension, the catch projections 13 are engaged in the catches 12 while achieving fixation of the set position by the spring bias tension. The setting disc 10 is actuated by inserting an actuating tool, such as a screwdriver, into the receptacle 15 and subsequently rotating the setting disc 10 around the center of the actuating axis 7. The actuating tool passes through the outer wall 6 of the housing 1 in the area of the cutout 14, so that it is only possible to turn the setting disc 10 until the actuating tool hits the particular frontal delimitation edges of the cutout 14. Even if this is performed with a comparatively high application of force, the actual actuator 3 is not mechanically impinged in this way, this finally also applying for possibly applied axial forces, because they are predominantly absorbed by the shoulder 9 of the actuating element 5 resting on the circuit board 4. Stepped intermediate positions may be set during the adjustment by the catches 12 and the catch projections 13, which may be made visually clear by markings 16 applied on the outer side of the outer wall 6. Alternatively to the exemplary embodiment shown, it is also possible to provide a displaceable actuating element 5 instead of a rotatable actuating element 5, in particular if a switch is to be actuated as the actuator 3 in this manner. In this case, the actuating element 5 can also be provided with a receptacle, into which a tool is inserted, using which a displacement of the actuating element 5 is possible within a cutout 14 in the outer wall 6. The actuating tool would also press against the front edges of the cutout 14 at the end of the displacement travel in the case of this solution, so that overloads of the actuator 3 itself are also prevented here. The actuating element 5, in particular its section lying in the area of the cutout 14 here, can be illuminated viewed from the interior of the housing 1 by an LED, so that either the recess 15 in the actuating element 5 or the entire area of the cutout 14 in the outer wall 6 is clearly visually recognizable. Of course, arbitrary other suitable illuminants may also be used.
6 The circuit board 4 and the at least one actuator 3 may advantageously be used to control the electric drive of a drawer or a comparable furniture part. In any case, the invention offers the advantage that actuators may be used which are manufactured in a relatively cost-effective manner and without special consideration of mechanical stability, because mechanical damage of the actuators is practically prevented by the described design. This is also true if solely mechanical or fine-mechanical components are provided as the actuators 3.
