Definitions

  • the invention relates to a damping device, in particular for the return movement caused by spring force the driver slide of an ignition switching device for gas stoves, as described in DE-19610522 A1.
  • a driver slide by turning one of the gas valve knobs counterclockwise over a ramp and a switch cam moved against spring force to an electric Switch contact close in the primary circuit of an ignition transformer lies.
  • the hollow return spring is released and the slide moves spring back to its starting position.
  • the invention is therefore based on the object of a damping device for the spring-loaded return movement of a driver slide, especially for an ignition switching device for gas stoves, to create a defined sequence of movements taking into account the spring characteristics of the return spring guaranteed.
  • an O-ring rests almost relaxed preferably on a triangular pin of the slide.
  • the O-ring becomes constricted pulled, and it deforms.
  • the compression coil spring that the Carrier slide moves back to the rest position is now on most excited. So she exercises her greatest power, and that Driver slide is released by the switch cam, and it returns to the rest position, with the O-ring through the Bottleneck is pressed. That means that when the compression coil spring exerts its greatest power, the O-ring through the narrowest point of the trajectory is pressed. If the strength the compression coil spring decreases, the movement channel widens and the O-ring can relax and return to its rest position to return.
  • the invention ensures that the movement of the driver slide defined when returning to the rest position is braked and that the annoying impact noise avoided or at least reduced.
  • Fig. 1 shows a view of an ignition switching device according to DE 19610522 A1.
  • a switch panel Gas valves not shown, arranged with their control shafts 2.
  • Each control shaft 2 carries a switch cam 11 and all Switch cams 11 act via a spring tongue 14 with a driver slide 12 together, in one on the aperture of the Gas stove fixed console 16 mounted displaceably is.
  • the driver slide 12 is by a compression coil spring 15, which is supported on the console 16, against one Stop not shown in the drawing according to FIG. 1 biased to the right.
  • This slider which from each control shaft 2 via the associated switching cams 11 and the ramp 3 according to FIG. 1 displaceable to the left is cooperates with a switch contact 13 in the primary circuit an ignition transformer, not shown in the drawing lies.
  • the ramp 3 are of spring tongues 14 worn, which during the return rotation of the control shaft (according to Fig. 1 clockwise) and dodge the slider left in its position.
  • This damping device has an elastic O-ring 21 on which is essentially triangular in cross section Pin 23 is placed with play.
  • the O-ring is supported in the direction of the return switching movement of the driver slide on a support member 25 which, like the pin 23 from Driver slide 12 protrudes.
  • the console 16 points in the range of motion of the pin 23 and the O-ring 21 one with respect the displacement axis 27 has a symmetrical recess 29, the edge boundary clearly shown in FIGS. 2 to 5 is.
  • This recess 29 essentially has one elliptical section on which the O-ring adjusts in the rest position of the slide 12 (Fig. 2).
  • This elliptical Section goes about converging boundaries 33 in a rounded constriction 35 in which the O-ring 21st is squeezed together laterally and thereby an increased Exerts frictional force on the driving slide 12 leading him.
  • the recess 29 is on both sides by fixed console parts covered so that the O-ring is secured against jumping out is held in this recess.
  • Fig. 2 shows the rest position of the slide and in this is the circular O-ring only slightly elliptically deformed and almost at rest relaxes on his triangular, Pin 23.
  • the driver slide 12 by turning an adjusting shaft 2 in a counterclockwise direction according to the drawing 3, the O-ring is moved laterally as shown in FIG. 3 squeezed together when passing through the narrow point 35 (FIG. 3) and then reaches its end position according to FIG. 4, in the he is relaxed on the side. In this position falls the switching cam 11 from the ramp 3 and the slide is shifted to the right by the spring 15.
  • the return spring 15 has its greatest force and 5 the O-ring is compressed by the constriction 35, whereby the slider corresponding to the increasing Frictional force is delayed.
  • the damping device can be versatile can also be used elsewhere where the problem is a slide against spring force after a certain Braking characteristic.
  • Such slide controls can be found, for example, in other household appliances, such as Washing or drying machines, but also in other areas of the technique.
  • the invention has been defined above in connection with a Braking a linear movement described. It is, however, through appropriate training of the management means also possible a rotating movement or one on one to slow down the curved path.
