Definitions

  • Electrical switches, regulators or control devices such as, for example, according to DE-C-26 04 783 (corresponding to GB 1 577 852) or DE-C-26 25 716 (corresponding to US Re 31 597) have a driven element in the form of a cam disk, Setting curve or the like, which acts directly or indirectly on contacts, switches or the like, and an adjusting shaft which drives this element, and also latching elements driven by the adjusting shaft.
  • the adjusting shafts are either permanently connected to the driven element or are inserted into it and are therefore non-rotatable.
  • the shaft is axially fixed, for example, by engaging in housing parts. This determination will be made during the Mounting the device causes, for example, by attaching an outer housing plate.
  • controllers or switches are often installed in devices that have a very different design, position of the operating elements, etc., it is necessary to provide different lengths and shapes of the setting shaft. Furthermore, other devices, for example attachment switches or additional switches, which are driven by the same setting shaft, can also be connected to controllers or switches. Here either an indirect coupling has to be made, which works less precisely due to a necessary play, or a special type of switch or controller with a correspondingly extended axis must be provided.
  • the object of the invention is to provide a device in which greater flexibility of installation is possible without increasing the variety of types.
  • the device can therefore be mounted without the setting shaft and can also be delivered in this condition to the manufacturer of the finished device, for example a kitchen stove. This can then attach a corresponding setting shaft according to its individual installation conditions, which it can simply plug in. This can be in the length, their connection dimensions and the connection system, for. B. for a knob, vary and can also z. B. on the remote side have appropriate extensions to operate additional switches or the like.
  • the z. B. may be flanged to the device.
  • the setting shaft can have a profile, by means of which it can be connected to the driven element in a rotationally fixed manner.
  • the axial fixing can be made by an automatic, for example barb-like connection.
  • this quick connection is clamped as a spring sheet metal part in a circumferential recess of the adjusting shaft and has a spring catch which engages behind a shoulder on the driven element, while on the other hand a stop projection ensures the securing in the direction of insertion.
  • This spring clip can lie in a recess of the adjusting shaft and can thereby also guide it laterally.
  • Switchgear are often intended to prevent unwanted or unauthorized operation, e.g. B. be secured by children, in which in addition to a rotation of the control button still an axial movement, for. B. a push-in is required to come to a zero position.
  • both the driven setting element such as the switching cam and a locking disc are connected to the setting shaft in a rotationally locking manner, but only one of these elements, namely the locking disc in the axial direction.
  • the spring clip thus engages the locking disc, which is resiliently loaded towards the user, so that he can push the locking disc axially out of its locked position by pressing it in and then make the corresponding rotation.
  • the spring between the locking disc and the adjusting element is effective, these elements secure one another in their position before the plug-in shaft is inserted.
  • the locking element and / or the adjusting element can also be held in position in the radial direction by surfaces of the device housing before the shaft is inserted.
  • the device shown in FIG. 1 is a tacking energy control device for electric heating devices, in particular cooking devices, which has a bimetal which is heated by a control heating together with the main heating switched by the device and which has the working contact for tacking the energy supply to an electric heating device, not shown controls.
  • the device has a housing 12 and electrical plug-in connection lugs 13 on its rear side.
  • the power released, ie the relative duty cycle, can be set via an adjusting shaft 14.
  • the setting shaft 14 also actuates signal contacts via a setting element 18 (FIG. 2), a double-pole disconnection which, when switched off, brings about a complete disconnection from the mains, and can also actuate additional contacts of any kind.
  • a setting element 18 FIG. 2
  • Fig. 2 shows the setting shaft 14, its arrangement in the device 11 and its connection with the elements driven by it.
  • the adjusting shaft is a metal profile of generally circular cross-section (FIGS. 3 and 4), which has flattenings 19, 20 at two opposite points.
  • the flat 19 is an approximately rectangular in the direction of the axis 21, i. H. longitudinal recess 22 is provided, while a differently shaped, here circular arc limited longitudinal groove 23 is provided opposite.
  • the setting shaft has two circumferential, relatively flat depressions or annular grooves 24.
  • Lateral clamping legs 26 of a clamping bracket 25 engage in the upper annular groove 24 and serve to hold the adjusting knob 17 which is fitted thereon and which has a recess designed in accordance with the profile of the adjusting shaft.
  • the spring clip is made from a cross-shaped sheet metal blank, the section 31 extending the section 29 being bent over 180 degrees and also extending in the direction of the device 11.
  • a stop section 32 is bent radially outwards. It is located at an axial distance from the free end 33 of the latching section 30.
  • a latching element 34 is fixed, which has the shape of a circular disk with a central opening 35 corresponding to the setting shaft profile. The latching element 34 is under the force a helical spring 36 pressed against the operator-side inner wall of the housing 12.
  • the latching element 34 With a cutout 37 on its circumference, the latching element 34 is latched into a stop tab 38 bent out of the sheet metal material of the housing, which together with the cutout 37 forms a latching means which can be disengaged. Projections 39 arranged around the circumference of the latching element 34 guide the latching element 34 between them, so that it remains in the orientation shown even when the adjusting shaft 14 is not inserted.
  • the setting shaft protrudes into an opening 40 correspondingly profiled in it in the setting element 18 and possibly also completely through it.
  • the setting element 18 contains a setting curve or cam 41 and a bearing pin 42 which leads in a corresponding bore in the housing 12, but which permits a certain amount of play.
  • the setting element 18 has a recess 43 which faces the operator side and widens the opening 40 and in which the helical spring 36 is arranged.
  • the device 11 is with all parts except the adjusting shaft 14 fully assembled, ie an outer housing cover is also attached.
  • the locking and adjusting elements 34, 18 are guided by the bearing pin 42 and the projections 39 in the radial direction to the axis 21 and are also axially fixed by the coil spring 36.
  • the controller can be sent in this form. It can also be adjusted beforehand with a shaft corresponding to the setting shaft 14. Before it is installed in a complete device, for example a hob or another electric heating device, an adjusting shaft 14 which has been prepared in accordance with the requirements is inserted from the outside through the opening 44 in the housing 12.
  • the setting shaft can either be one of a variety of types differing in length, type of connection and possibly also material, or it can also be specially made for this case. It is advantageous that the adjusting shaft always has a constant profile and is only deflected accordingly, as must be provided with the annular grooves 24.
  • Spring clip 28 and clamping bracket 25 can be the same for all types of adjusting shafts and are only snapped or clamped. This shaft can then be inserted before or, if necessary, also after assembly of the device, so that it projects through the opening 44 and the openings 35 and 40 in the elements 34 and 18.
  • the front section of the spring clip 28 with the latching section 30 penetrates through the correspondingly shaped opening 35 in the latching element 34, the latching section 30 compressing and abutting the section 29.
  • the latching element 34 is thus not only fixedly connected to the shaft in the direction of rotation, but also axially, the latching by the automatic quick connection 30, 32 when inserting.
  • the controller is now finished and it is only necessary to push on the control button 17 after the controller has been installed in a corresponding plate 16 of the overall device.
  • the illustrated embodiment by means of an axially actuated anti-rotation lock (also called push-to-turn) works in such a way that the latching element 34 is fixed in the direction of rotation by the latching means 37, 38, as long as the latching disk on the adjusting element 18 is not opposed by pressure on the adjusting shaft 14 the force of the coil spring 36 is moved so that the stop tab 38 comes out of the cutout 37 and a rotation is carried out.
  • the adjusting shaft moves axially in the adjusting element 18. However, when rotating, both elements 18, 34 are taken together.
  • the stop flap and the cutout 37 snap back into one another, so that the device is again secured against unauthorized rotation.
  • the setting shaft can be axially locked in place either on a housing part or also on the setting element 18, for example an inner collar in the region of the recess 43.
  • Other quick connection means are also possible, but the spring clip described is particularly simple to manufacture and, above all, can be retrofitted to the adjusting shaft.
  • the invention is applicable to numerous types of adjustable devices, in particular to electrical switches, such as multiple cam switches, temperature regulators or, very particularly preferably in the described power control units.
