Definitions

  • the invention relates to a reusable shift lever according to the preamble of claim 1.
  • Reusable shift levers of this type are used for manual control of movements in several directions. By pivoting the shift lever in different directions, various control elements are actuated, which trigger a movement process in the respective assigned direction.
  • the control elements can be electrical switches, electronic proximity switches, pneumatic or hydraulic switching valves or other control elements which are switched on and off by the switching axis or which deliver a control signal proportional to the deflection of the switching axis.
  • Such shift levers can e.g. to control the movement of machine parts such as grippers, arms and the like. In particular, such shift levers are also used to control gaming and entertainment machines.
  • the manually operated reusable shift lever If the manually operated reusable shift lever is released, it must be returned to its basic position.
  • elastic forces are used to reset the shift axis. If only a few switching directions are provided, the restoring force can be generated by springs acting in each of these switching directions. With a larger number of switching directions, the restoring force is brought about by mounting the switching axis in a rubber-elastic material.
  • the remindstel- lun g of the shift lever by elastic forces "has the disadvantage that the elastic restoring force generating elements to wear and fatigue are subject. Therefore, the restoring force can be prolonged use of the shift lever by and spring elements may break.
  • the invention has for its object to provide a reusable shift lever which is practically no wear and fatigue subject to simple structure and high operational safety.
  • the restoring force for the shift axis is generated by a permanent magnet.
  • This magnetic restoring force is not subject to material fatigue. Since the switching axis with the swash plate sits freely in the hollow cylinder and is held only by the magnetic force, there are no mechanical connecting parts and bearings that are subject to wear. The shift lever therefore has a long service life even under heavy use.
  • the shift lever is extremely robust and, due to its purely permanent magnetic reset and the lack of mechanical bearings in the shift axis, it is reliable and not susceptible to faults.
  • the shift lever is not restricted with regard to the directions and the number of shift paths.
  • the directions and number of switching paths can be freely determined by the design of the link plate.
  • the same shift lever can be used for a wide variety of applications, with only the link plate for the respective application must be chosen accordingly. This has an advantageous effect on manufacturing costs and warehousing.
  • the shift lever can be easily converted for another application.
  • the reusable shift lever has a hollow cylindrical housing 10 which axially adjoins a portion of a larger and a portion of a smaller inner diameter.
  • the housing 10 can consist of a non-magnetic metal, preferably light metal or plastic.
  • a cylindrical permanent magnetic ring 12 is inserted in a snug fit.
  • a hollow cylinder 14 made of a low-friction plastic is also fitted.
  • the inner diameter of the two sections of the housing 10 and the inner diameter of the hollow cylinder 14 are selected such that the hollow cylinder 14 radially overlaps the magnetic ring 12 only on its outer circumference.
  • the hollow cylinder 14 has a radially inwardly drawn bottom 16.
  • the hollow cylinder 14 and the magnetic ring 12 are coaxially penetrated by a switching axis 20.
  • An operating button 22 made of plastic is cast onto the upper end of the switching shaft 20 made of steel.
  • a swash plate 24 made of a ferromagnetic material is pushed onto the switching axis 20 without play.
  • the swash plate 24 projects with an axial extension 26 into the magnetic ring 12.
  • Sleeves 28 and 30 are pushed above and below the swash plate 24 onto the switching axis 20 and are axially fixed on the switching axis by a snap ring inserted into a circumferential groove at the lower end of the switching axis 20 .
  • the swash plate 24 is axially fixed on the switching axis 20.
  • a screwed to the housing 10 cover 32 closes the hollow cylinder 14 on the upper end face and leaves only one central opening 34 through which the switching axis 20 and the sleeve 28 pass with radial play.
  • the swash plate 24 is rounded on its outer circumference in the axial direction and has only a slight radial play in relation to the hollow cylinder 14 in the area of its largest diameter.
  • the surface of the swash plate 24 facing away from the magnetic ring 12 slopes away from the inside towards the edge.
  • a link plate 36 is attached to the lower end face of the housing 10.
  • the link plate 36 is preferably screwed to the housing 10 so that it is detachable and replaceable.
  • a switching path link opening 38 is provided centrally in the link plate 36, through which the switching axis 20 and the sleeve 30 pass.
  • the link opening 38 is formed for a four-way shift lever.
  • the link opening 38 has four bulges 40 offset at an angle of 90 ° to one another, into which the switching axis 20 with the sleeve 30 can be moved.
  • Each bulge 40 is a control, e.g. a microswitch, assigned, which is actuated by the sleeve 30 when it is moved into the respective bulge 40.
  • the shift lever If the shift lever is not actuated, it is reset to its basic position with the coaxial alignment of the shift axis 20 in that the ferromagnetic swash plate 24 is attracted by the permanent magnet ring 12.
  • the restoring force of the shift lever is essentially determined by the magnetic force of the magnetic ring 12.
  • a further adjustment of the restoring force is possible through the choice of the diameter of the swash plate 24 in relation to the inside diameter of the magnetic ring 12, i.e. due to the radial overlap of swash plate 24 and magnetic ring 12, which determines the cross section available for the magnetic flux.
  • the magnetic force can also be matched by the axial thickness of the base 16 of the hollow cylinder 14. This base 16 acts as a separating disc between the magnetic ring 12 and the swash plate 24 and determines the gap between them which weakens the magnetic flux.
  • the shift axis 20 can be manually tilted out of the coaxial basic position against the magnetic restoring force by means of the control button 22.
  • the radial play of the sleeve 28 in the opening 34, the radial play of the neck 26 of the swash plate 24 in the magnetic ring 12 and the radial play of the sleeve 30 in the bottom of the housing 10 are selected so that the tilting movement of the switching axis 20 is not hindered thereby becomes.
  • the tilting movement is therefore limited only in that the switching axis 20 comes into contact with its sleeve 30 with the link opening 38 of the link plate 36.
  • Shift travel and shift directions of the shift lever are therefore determined by the bulges 40 of the link opening 38.
  • the spherical curvature of the outer circumference of the swash plate 24 is selected such that the swash plate 24 is guided through the hollow cylinder 14 with minimal radial play both in the coaxial basic position and in each tilted position.
  • the beveling of the upper surface of the swash plate 24 ensures that it lies essentially parallel to the cover 32 at the maximum tilt angle. This ensures optimal use of space and a minimal axial height.
  • Bores 42 in the cover 32 and with these aligned longitudinal grooves 44 in the outer lateral surface of the housing 10 and the link plate 36 are used to fasten the shift lever by means of threaded bolts.
