Definitions

  • the invention relates to an actuating device for a pull / push remote control for actuating an actuating member, the actuating member being able to be brought back from an initial position by forward movement into an end position and by backward movement.
  • Said pull / push remote controls are very similar to conventional Bowden cables or cable cables and, like these, consist of an outer flexible casing and an inner element which can be displaced relative to the casing for transmitting the operating movement, but this inner element, in contrast to that of a Bowden cable, except Can also transmit tensile forces.
  • Such remote controls are usually used to enable operating measures over a certain distance.
  • an organ that is to be actuated and is located in an inaccessible location can be actuated by means of a lever arranged at a convenient location via a corresponding pull / push remote control.
  • a lever arranged at a convenient location via a corresponding pull / push remote control.
  • an operating element at one end of the remote control, for example a lever, for initiating the operating measure in the remote control and the organ to be operated at the other end, a lever being generally also arranged here for recording and forwarding the movement.
  • a device whereby an organ to be operated can be operated optionally from two separate locations.
  • This device comprises a first and a second operating lever, each of which is connected via a push / pull cable to a coupler which in turn acts on a lever of the organ to be actuated.
  • a first and a second sliding element are arranged within the coupler, each of which has an end face and a notch and are displaceably mounted in a parallel arrangement with an intermediate space relative to the coupler. Each end of a cable is connected to a sliding element.
  • the device furthermore has an elongated switching element which can be pivoted relative to the coupler and has a first and a second end, the first end of which is provided with a double hook which can optionally engage in one of the aforementioned notches.
  • the second end of the switching element forms a T-beam, on which the sliding elements can act with their end faces. If the first operating lever is now moved so that the sliding element in question acts with its end face on the T-beam, the switching element is pivoted so that the double hook engages in the notch of the first sliding element, which has triggered the pivoting movement. So that the sliding element is positively connected to the coupler, so that the said member can now be operated by means of the first operating lever.
  • the invention has for its object to provide an actuator for a pull / push remote control so that the operation of an organ is optionally possible via two separate pull / push remote controls without mutual influence of the operating lever, sliding guides are avoided.
  • a generic actuating device in that it has two input levers, each pivotable by a pull / push remote control, and an output lever that is operatively connected to the actuator with two lateral stops, the common pivot axis of the input lever being related to the pivot axis of the output lever runs parallel and the input levers are arranged on both sides of the output lever and their free ends each form an engagement tongue and at the free end of the output lever a switching element which is pivotable transversely to its direction of movement is arranged with two recesses, the engagement tongues projecting into the recesses, the output lever by the input lever on the side stops in the forward direction and the switching element is designed so that this Initiation of a movement about one of the input levers is pivoted so that the other input lever is released.
  • Figures 1 to 3 show a functional model of an actuating device for a pull / push remote control with a base plate 1, in the left part of two control handles A and B are arranged, which can be used optionally for actuating an actuating device shown on the right.
  • the model consists of the base plate 1 with two bearing blocks 2 and 3 attached in its left part and two further bearing blocks 4 and 5 attached in the right part.
  • a first control lever 6 with the control handle A and a second control lever 7 with the control handle B are pivotably mounted on the bearing blocks 2 and 3, each of which acts on a pull / push rod 8 or 9 via corresponding articulated connections.
  • the operating levers 6, 7 are mounted on an axis 10 guided by the bearing blocks 2, 3 and by a Spacer 11 axially positioned.
  • an output lever 14 is mounted by means of a shaft 12, which has at its free end a switching element 15 that can be pivoted transversely to its direction of movement.
  • the shaft 12 has a rectangular cross section in the region of the lever 14, to which a corresponding opening 14a located at the lower end of the lever 14 and transverse to the lever is adapted in a form-fitting manner.
  • the output lever 14 has a projecting stop 14b and 14c on each side. In the area between the opening 14a and the free end of the lever 14, the lever 14 has a transverse bore 14d running parallel to the opening 14a, into which an axis 22 is inserted.
  • each input lever 17, 18 On both sides of the output lever 14, an articulated and a free end input lever 17, 18 with a bearing bore located at its articulated end is pushed onto the axis 22 and axially secured by a shaft lock.
  • the free ends of the input levers 17, 18 each form an engagement tongue 17a, 18a which, as will be shown, can optionally engage in the switching element 15.
  • the common pivot axis of the input levers 17, 18 runs parallel to the pivot axis of the output lever 14. In the area between its two ends, each input lever 17, 18 has a connection point in which the respective pull / push rod 8, 9 is articulated to it.
  • the operating levers 6, 7 are connected to the input levers 17, 18 via the pull / push rods 8, 9 so that when the levers 6, 7 are actuated, they perform a movement following these levers.
  • the input levers 17, 18 interact with the lateral stops 14b, 14c in such a way that the input lever 17, 18 actuated in each case moves the output lever 14 via the relevant stop 14b, 14c in the direction of the end position pushes on.
  • This entrainment movement is only achieved by placing the respective input lever 17, 18 against the stop in question. Therefore, movement of the input levers 17, 18 in the opposite direction due to the stops 14b, 14c has no influence on the output lever 14.
  • the movement of an organ to be actuated takes place via the shaft 12, which is to be connected to the organ either directly or via a lever linkage.
  • the switching element 15 is pivotally mounted on a pin 19 and axially secured by a washer 21 and a shaft lock 20.
  • a spring-loaded pressure element 16 ensures that the switching element 15 always remains in the position into which it was brought by one of the input levers 6, 7.
  • the switching element 15 is constructed symmetrically and has a recess 15a, 15b on each side into which the engagement tongues of the input levers 17, 18 protrude.
  • the upper area of the switching element 15 is designed as a cover, as a result of which the recesses 15a, 15b are protected from the outside.
  • FIGS. 1 to 3 show details of the switching element 15 and the pin 19 on which it is mounted.
  • the one in FIGS. 1 to 3 visible cover cut away, so that the effective shape of the switching element 15 with the recesses 15a, 15b can be seen, the upper limits in the image of the recesses 15a, 15b, as shown by an inclined actuating surface 23 and 24 and the im Image lower boundaries are formed by a hook 25 and 26 respectively.
  • the engagement tongues 17a, 17b are in principle of rectangular cross-section, but the areas in the lower picture are chamfered outwards and are provided with a transition radius on their opposite sides. Between the flat side of the switching element 15 facing the respective engagement tongue 17a, 17b and the relevant recess there is a distance d.
  • the switching element 15 is shown together with the engagement tongues 17a and 18a in the initial position of the adjusting device. In this position it is locked in its middle position and both control handles A and B are in their initial position. Starting from this state of the adjusting device, the input levers 17, 18 can be moved on an arc in the direction of the arrow 27 (operating direction).
  • the engagement tongue 18a remains in its initial position. However, if the actuation starts from the input lever 18, the movement sequence is the same as described above, but the switchover element is pivoted counterclockwise immediately at the start of the movement. Thus, the output lever 14 can be operated either by the control handle A or B. If the engagement tongue, which is currently not in engagement with the switching element 15, is moved by a thoughtless measure, it cannot be brought into engagement with the switching element 15. Such a measure thus has no influence on the movement of the output lever 14. This ensures that a mix of operating measures cannot take place.
  • the switching element 15 is so designed that it when a movement is initiated via one of the input levers 17, 18 is always pivoted such that the other input lever 18, 17 is released.
  • FIG. 6 shows an arrangement for actuating a valve 28, consisting of an actuating device 29, two operating devices 30 and 31 located at different locations, each with an operating lever 32 and 33.
  • the operating devices 30, 31 are each via a pull / push remote control 34 and 35 connected to the actuating device 29.
  • the actuating device 29 has an output lever 38 with a switching element 39.
  • the rods 36 and 37 are used to connect the pull / push remote controls 34, 35.
  • the kinematic processes correspond in principle to those already described in connection with FIGS. 1 to 5 are described. Accordingly, the rods 36, 37 are articulated to input levers which are not visible here and which act on the output lever 38 via corresponding stops and the switching element 39.
  • the output lever 38 is connected directly to the shaft 40 of the valve 28, so that the adjusting device 29 in this case does not have its own bearing for the output lever 38.
