Definitions

  • the rigid control lever is fastened at its lower end in a rubber plate or the like forming the housing base, which enables the control lever to be pivoted manually.
  • the lever stop consists of a disk-shaped sheet in which two longitudinal slots which detect the lifting path are arranged in a cross shape, the four end edges of which each form a stop surface for the control lever which defines a switching position of the control lever. Two pairs of switches are arranged in a cross shape to one another in the housing, the control lever in its vertical neutral position being located exactly in the middle between the four switching plungers.
  • the disc-shaped lever stop is screwed against the upper housing flanges with the interposition of a console, so that the lever stop and housing are braced against the console from opposite sides.
  • the invention is therefore based on the object of improving the switching device explained at the outset in such a way that always precise lever travel of the control lever is ensured.
  • a first slot is provided in the bottom of the housing part and a second slot is provided in the lower edge of the end plate, which are arranged relative to one another in such a way that a pivoting tool can engage in both slots at the same time and can pivot the end plate relative to the housing by twisting when the bolt-nut connections projecting through the horizontal slots (47) are released.
  • control lever In order to ensure the pivotability of the control lever, it is expedient to produce the control lever itself from flexible flat material with a rectangular cross-section, the narrow sides of which lie parallel to the lever pivoting path, instead of the base plate of the known switching device, which is made of rubber or the like. This ensures that the control lever is evenly flexible and resistant to aging and independent of weather influences.
  • a particularly simple and expedient adjustment of the lever stop can be achieved if the housing part is essentially U-shaped and the vertical legs forming the U-legs can be pivoted elastically, so that the end plate, vertical legs and the bottom forming the U-web are elastic Form quadrilateral that is adjustable relative to the lever pivot path in desired positions.
  • the switching device in the switching device according to the invention, it can be ensured by appropriate adjustment of the end plate that the control lever does not press the switching plunger beyond its switching point.
  • the new switchgear is characterized by being completely maintenance-free. There are no components that are in sliding contact with each other.
  • the adjustment of the stop device can be carried out in a simple manner without the use of a special tool.
  • a lever-operated switching device 1 in which a flexibly designed control lever 30 is fastened with its lower end to a housing part 20 and has a handling button 34 at its upper free end.
  • This control lever can be pivoted forwards or backwards along a defined lever path in order to actuate a front or a rear switch 10, 11.
  • an adjustable stop device 40 is provided in order to protect the switching plungers 12, 13 of these switches 10, 11 from overdriving.
  • switches 10, 11 are attached to flanges 24, 25 of an essentially U-shaped housing part 20 by means of bolts 53, 54 and nuts 55. They are on-off switches that are usually used to control hydraulic devices and are switched by actuating their switching plungers.
  • the vertical legs 22, 23 of the housing part 20 which form the two U-legs merge at their upper ends at right angles into the inwardly projecting, vertically directed flange 24, 25.
  • the U-web of the housing part 20 is formed by an essentially rectangular bottom 21 which carries the two vertical legs 22, 23 at opposite ends.
  • a first slot 26 is provided in the bottom 21, the function of which will be explained later.
  • the bottom 21 there is also an opening 19 (see in particular FIG. 3) which serves to receive the lower end 31 of the control lever 30, which is provided with an external thread.
  • the lower end 31 is fastened to the housing base 21 by means of a pair of lock nuts 32 which clamp the housing base 21 and a bracket 5 between them, through whose opening 6 the lower end 31 of the control lever is inserted.
  • the lock nuts 32 thus serve simultaneously to secure the control lever 30 and to fix the housing part 20 on the console 5.
  • the housing part 20 could of course also be fastened to one of its vertical legs 22, 23 on a suitable console.
  • the control lever 30 consists of flexible flat material with a rectangular cross-section, the narrow sides of which lie parallel to the lever pivoting path, so that the wider sides extend parallel to the vertical recesses 22, 23.
  • the external thread at the lower lever end 31 is only provided on the narrow sides.
  • the upper lever end 33 is also provided with an external thread onto which the handling button 34 is screwed.
  • the stop device 40 has a substantially rectangular vertical end plate 41 which is fastened to the flanges 24, 25 by the bolts 53, 54 and nuts 55, which also serve to fasten the switches 10, 11.
  • Upper bolts 53 are inserted through corresponding bores 53a in the end plate 41 and through bores 53b in the flanges 24, 25.
  • Lower bolts 54 protrude through horizontal slots 47 in the end plate 41 and bores 47a in the flanges 24, 25 (see FIGS. 3 and 4).
  • the slots 47 are used in connection with a second slot 48 in the lower edge of the end plate 41 and in connection with the first slot 26 in the housing bottom 21 for adjusting the stop device 40.
  • the end plate 41 of the stop device 40 carries at its upper edge a pair of horizontally extending tabs 42, 43, the mutually facing inner edges 44, 45 of which form the abovementioned stop surfaces for the control lever 30.
  • an adjusting device which consists of the slots 47 and the two slots 26, 48.
  • the adjustment device primarily enables the stop device 40 to be pivoted relative to the housing part 20.
  • the nuts 55 of the lower bolts 54 are loosened; then z. B. a flat screwdriver, as indicated in Figure 1 by the dashed lines 65, inserted into the slots 26, 48; by slightly turning the screwdriver, the end plate 41 can now be pivoted relative to the housing part 20.
  • This pivoting is made possible by the Slits 47 in the end plate 41 and due to a certain elasticity of the vertical legs 22, 23 of the housing part 20.
  • the end plate 41, vertical legs 22, 23 and housing base 21 together form an elastic quadrilateral joint with articulation points 53a, the pivoting taking place by elastic pivoting of the vertical legs mentioned .
  • the switches 10, 11 essentially maintain their position when the end plate 40 is pivoted, as a result of which only the positions of the stop surfaces 44, 45 change. As a result, the stop surfaces 44, 45 can be adjusted with respect to the switching disturbances 12, 13, so that their oversteer can always be prevented by the control lever 30. After adjustment, the nuts 55 of the lower bolts 54 are tightened again in order to fix the end plate 41 in the desired position relative to the housing part 20.
