Definitions

  • Such an actuator - but without a locking device - has become known from EP-A-0 271 635.
  • a driver (9) To disengage, a driver (9) must be pushed away from the cam (10) of the sliding nut (5) while overcoming an elastic restoring force.
  • the restoring force is applied by a spring arm (8) of the push rod (7) which has a sliding cam (17) on the back.
  • This sliding cam (17) is supported over the largest part of the sliding path the push rod (7) on a housing-fixed blocking surface (12), which has recesses (13, 14) only where the spring arm (8) must be deflectable elastically transversely to the sliding path for disengaging.
  • the disadvantage is that the clutch has no idle stroke and that relatively large forces are required to disengage, because the transverse movement of the driver (9) must be forced all the way against the restoring force of the spring arm (8).
  • a locking device is already provided in this actuating element, which has a locking lever (44) which is pivotably mounted on a plunger (20) and which can engage with an extension (46) in a locking recess (45) in the housing (43).
  • This locking device is considered to be disadvantageous in that its dimensions are limited because of the bearing in the ram and that it can therefore not be made sufficiently stable.
  • the object is therefore to propose an actuating element of the type mentioned, in which the clutch can perform a defined idle stroke and can be actuated without great effort and in which a sufficiently stable locking device can be provided.
  • the necessary transverse movement for disengaging is achieved partly by an evasive movement of the driver and partly by an elastic deflection. It is possible within the framework of the design specifications to vary the transverse movement components within wide limits and to adapt them to the respective needs. Accordingly, it can also be determined how large the force to disengage should be. It can be significantly lower than in the known couplings, in which the return spring is effective over the entire disengagement path. With conventional control elements With regard to the disengagement, the drive had to be designed much stronger than was necessary for the movement of the plunger alone. With the invention, on the other hand, only a slight oversizing of the drive is required, measured by the main purpose of the actuating element, because when disengaging, only a "remaining path" has to be covered against the force of the return spring.
  • the plunger has only the "passive” elements of the locking device and that the "active" elements are mounted in the housing. This gives greater freedom for the design of the individual elements, in particular for their dimensioning with regard to the load when trying to open them violently.
  • a plunger 1 is expediently formed from a plastic part according to the invention, in which a circular base part 3 is formed between the connection eyelet 2 and the actual plunger 1, which has a circumferential recess for fastening a bellows. After assembly, the connection eyelet 2 and base part 3 lie outside the control element housing.
  • the plunger 1 has an essentially flat, rectangular cross section. On one longitudinal side there is a groove-shaped recess 5 running centrally in the sliding direction, into which a cam 27 of the sliding nut 24 engages after assembly (cf. FIG. 5). On the opposite side, a rectangular recess 6 is formed, which serves as a sliding bearing for the driver 16 (see FIG. 3) and is wider in the sliding direction by the intended idle stroke than the driver 16.
  • a rectangular opening 7 is provided through which the centrally arranged projection 20 of the driver 16 extends through.
  • the rear end of the plunger 1 is divided into two arrow-shaped extensions 8 with recesses 10 on the edge.
  • the plunger 1 is thus adapted to the shape and function of the pawl 12 (see FIG. 2).
  • the hooks 14 of the pawl 12 engage in the recesses 10 on the edge, while the lever 13 of the pawl 12 engages through the recess 9 and can be gripped there by the sliding nut 24.
  • guide webs 4 are provided, which engage in corresponding grooves of the housing or cover when the actuator is fully assembled.
  • the pawl 12 according to FIG. 2 is also advantageously formed from a plastic part. It has a hook 14 at the top and bottom and a lever 13 in the center, which is offset by approximately 135 ° with respect to the hook 14 with respect to the pivot axis.
  • a cylindrical pin 15 is formed above and below, which are intended to engage in corresponding recesses in the housing and cover of the actuating element.
  • the driver 16 consists of a rectangular plate 17 made of elastic material with two edge-side projections 18 which extend on one side of the plate 17 over the entire height thereof.
  • a projection 19 or 20 is provided in the center on each side, but these only extend over part of the height of the plate 17.
  • Dash-dotted line also indicates the plunger 1, the rectangular recess 6 of which is wider than the rectangular plate 17 by the length of the desired idle stroke.
  • the housing-fixed link 21 is shown in addition to the driver 16. It has recesses at the end 22, in which the edge-side projections 18 can engage when the driver 16 is displaced relative to the link 21 into the end positions.
  • recesses 23 are also provided, into which the projection 19 of the driver 16 dips so that the plate 17 can bend elastically when the cam 27 of the sliding nut 24 moves over the projection 20 of the driver 16 when disengaging.
  • the sliding nut 24 has a groove 28 for positively guiding the shift rod 29 according to FIG. 6.
  • an axially parallel web 31 is provided on its cylindrical base body 30, which extends over a part of the length of the shift rod 29 at an angle to the remaining partial length.
  • a transition piece 32 is provided in between.
  • Fig. 7 the plunger 1 is extended, i.e. the connecting eye 2 has reached the position farthest from the housing 34 and the bellows 39 is stretched.
  • the contact web 11 has released the contact 41 while the contact 42 is pressed by the switching rod 29.
  • the sliding nut 24 has been moved into its left end position by the electric motor 35 via the spindle gear 36 and has brought the driver 16 into the position shown.
  • the cam 27 of the sliding nut 24 has migrated over the projection 20 after the projection 18 of the driver 16 is immersed in the recess 22 of the link 21 and the projection 19 in the recess 23 and the driver 16 has bent elastically downward.
  • the sliding nut 24 and driver 16 are thus decoupled, i.e.
  • the plunger 1 can be moved from the outside into its opposite end position without the electric motor 35 and spindle gear 36 hindering this movement.
  • the switch contacts 41, 42 belong to microswitches 37, of which only the upper one can be seen.
  • the electrical connections are designated by 38.
  • the function of the pawl 12, which can be pivoted against the return spring 40 for engagement in the recesses 10 of the plunger 1, is discussed in the description of FIG. 9.
  • Fig. 8 the position "locked” is shown. All reference numerals have the same meaning as in FIG. 7. Only the parts that have changed their position or shape with respect to FIG. 8 will be discussed.
  • the contact pin 11 is shifted to the right and has pressed the contact 41 while the contact 42 is released from the switching rod 29.
  • the plunger 1 has moved into its right end position, ie the connecting eye 2 has reached the position at least distant from the housing 34 and the bellows 39 is compressed.
  • the driver 16 is located again in a somewhat tilted position, which is analogous to that explained with reference to FIG. 7. In other words, sliding nut 24 and driver 16 are decoupled and the plunger can be moved from the outside into the opposite end position without the electric motor 35 and spindle gear 36 interfering.
  • FIG. 9 corresponds to FIG. 8.
  • the plunger 1 When secured in position, the plunger 1 cannot be moved, i.e. he holds the lock in the "locked” position. While - as explained - in the "locked” position according to FIG. 8, the disengaging is to enable an engagement in the locking mechanism without using the actuating element, in the "secured” position it is ensured that the possibilities of engagement at the lock, which are otherwise due to the actuator consist, be blocked. An actuating element is thus realized which corresponds to all of the conditions mentioned at the beginning.
