Definitions

  • Such an embodiment can be found in GB-PS 985 298.
  • the lever stop consists of a disk-shaped sheet in which two longitudinal slots defining the lever path are arranged in a cross shape, the four end edges of which each form a stop surface for the control lever that 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.
  • lever stop is attached to the flanges by means of upper bolt-nut connections inserted through holes in the end plate of the lever stop and via lower bolt-nut connections inserted through horizontal slots in the end plate.
  • first slot is provided in the bottom of the housing and a second slot is provided in the lower edge of the end plate of the lever stop, which are arranged with respect to one another in such a way that a pivoting tool simultaneously engages in both slots and by twisting the lever stop relative to the housing can pivot when the lower bolt-nut connections are loosened.
  • a particularly simple and expedient adjustment of the lever stop can be achieved if the housing is essentially U-shaped, and that the vertical legs forming the U-legs can be pivoted elastically, so that the lever stop, vertical legs and the bottom forming the U-web form an elastic quadrilateral joint, which 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 lever stop that the control lever does not press in 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 lever stop can be adjusted 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 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 lever stop 40 is provided in order to protect the switching plungers 12, 13 of these switches 10, 11 from being overdriven.
  • FIG. 1 shows in detail that the switches 10, 11 are attached to flanges 24, 25 of an essentially U-shaped housing 20 by means of bolts 53, 54 and nuts 55. It is an on-off switch that is commonly used to control hydraulic equipment and by acting on it their switching plungers are switched.
  • the vertical legs 22, 23 of the housing 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 20 is formed by a substantially 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 attached to the housing base 21 via a pair of lock nuts. 32, which clamp between them the housing base 21 and a bracket 5, through the opening 6 of which the lower end 31 of the control lever is inserted.
  • the lock nuts 32 thus serve at the same time for fastening the control lever 30 and for fixing the housing 20 to the console 5.
  • the housing 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 pivot path, so that the wider sides extend parallel to the vertical legs 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 lever stop 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 holes 53a in the end plate 41 and through holes 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 base 21 for adjusting the lever stop 40, as will be explained in more detail later.
  • the end plate 41 of the lever stop 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 adjustment device which consists of the slots 47 and the two slots 26, 48 and works as follows:
  • the adjustment device primarily allows the lever stop 40 to be pivoted relative to the housing 20.
  • the nuts 55 of the lower bolts 54 are loosened; then e.g. a flat screwdriver, as indicated by the broken lines 65 in FIG. 1, is inserted into the slots 26.4 $ and perpendicular to the plane of the drawing; by slightly turning the screwdriver, the end plate 41 of the lever stop 40 can now be pivoted relative to the housing 20.
  • This pivoting is made possible by the slots 47 in the end plate 41 and by a certain elasticity of the vertical legs 22, 23 of the housing 20. by elastic pivoting of the vertical legs mentioned.
  • the switches 10, 11 essentially remain in their position when the lever stop 40 is pivoted, as a result of which only the positions of the stop surfaces 44, 45 change.
  • the stop surfaces 44, 45 can be adjusted relative to the switching plungers 12, 13, so that their oversteer can always be prevented by the control lever 30.
  • the nuts 55 of the lower bolts 54 are tightened again in order to fix the lever stop 40 relative to the housing 20 in the desired position.
