Definitions

  • the invention relates to a device for manual control according to the preamble of Claim 1.
  • the object of the invention is a small-sized device for manual control to propose that basically does not require displacement.
  • the solution provides that the control is provided in the or each Direction is biased and that the or each transducer is one to a force sensor includes sensor surface that is perpendicular to the intended direction is arranged, and with which the control element interacts.
  • the device enables it with no or only very little due to the preload Movements (swivel, shift) of the control to get by. It is also possible to add a highly sensitive small linear force sensor use, which detects the hand force acting in a intended direction and in implements a corresponding control signal.
  • the sensor comprises a bridge circuit of electrical resistors and the electrical Resistors are applied to the sensor surface.
  • the sensor is particularly temperature-stable if a Ceramic plate is used.
  • the control element is used to keep the force acting on the sensor surface small via a first effecting a preload in the intended direction elastic element supported on the plunger.
  • the sensor surface, the plunger and the elastic one simplify the assembly Element arranged in a common sensor housing, on the inside the first elastic element is supported.
  • the sensor is in two opposite directions (direction and opposite direction) operable when the first elastic element with the interposition of one of accessible from the outside and by means of the control element in the intended direction actuatable actuating element via a second elastic element to the Supports the inside of the sensor housing.
  • the sensor surface is advantageously parallel or transverse arranged to the longitudinal axis of the control element.
  • a particularly small construction provides that the two elastic Elements as different diameter coil springs and that Actuator in the manner of a hat with an edge and a recess like this are designed so that the coil spring with the larger inner diameter supports on the edge and on one inside and that the coil spring with the smaller outer diameter can be used in the recess and on the bottom of the Depression and supported on the plunger.
  • control element For basic support of the control element is a coaxial to the longitudinal axis Provided metal tube which is passed through the control element.
  • one converter is provided in each of the three directions, all three directions and the parallel longitudinal axes of the transducers perpendicular to it to each other.
  • control element In order to detect the actuation state of the control element, the control element a light barrier is provided when the control is gripped by hand emits an actuation signal.
  • a high level of operating convenience is achieved if there is a missing actuation signal
  • the converter signal is zeroed.
  • the Control element from actuatable switching elements for example in the form of Push buttons provided.
  • the device 1 shows the device 1 for manual control, which is particularly suitable for a driving and lifting drive of a load lifting device (not shown) can be used.
  • the device 1 consists of a control element 2 designed as a handle. In the upper area of the control element 2 buttons are also provided as switching elements 3, which with can be easily reached and operated with the thumb, e.g. an emergency shutdown trigger.
  • a metal tube 4 is passed longitudinally through the control element 2 runs coaxially to the longitudinal axis of the control element 2 and on which it is movable is attached. At the top is a rope (not shown) on the metal tube 4 and at the lower end a load suspension device, also not shown, can be attached.
  • To enter a Control element 2 can be gripped by the hand of an operator and the desired value can be loaded with a hand.
  • This manual force application is carried out by an electrical device shown in FIG Converter 5 converted into an electrical signal, which in the direction (longitudinal direction) of the converter 5 corresponds to the effective component of the hand force.
  • FIG. 3 shows the built-in converter 5 according to FIG. 2 in an enlarged view Presentation
  • 4 shows the transducer 5 in a spatial cross section and in FIG. 5 the housed converter 5 is shown.
  • the converter 5 shown in FIG. 4 has a sensor surface 6 of a ceramic plate 7 a cylindrical ceramic element 8 with a U-shaped cross section.
  • a bridge circuit not shown, of electrical resistances applied with electronics (not shown) connected is.
  • On the ceramic plate 7 lies on the sensor surface 6 opposite side a ball 9, which in the curved head surface 10 Tappet 11 is inserted, the ball 9 partially out of the head surface 10 protrudes.
  • the control element 2 acts via the plunger 11 via the ceramic plate 7 with or on the sensor surface 6.
  • the action takes place via nested springs 12a, 13a with different diameters as elastic elements 12, 13 with the interposition of an actuating element 14.
  • the actuating element 14 is hat-shaped.
  • the actuator 14 is within the housing 18 in the in Fig. 5 shown arrow directions from a zero position.
  • the coil spring 12a causes the control element 2 to be preloaded in Longitudinal direction of the coil spring 12a is supported. At the same time it experiences this Actuator 14 a counterforce from the coil spring 13a.
  • the selection of the Spring constants of the two coil springs 12a, 13a take place in such a way that the its zero position actuator 14 based on the housing 18 approximately is in its middle position.
  • the two coil springs could be very stiff as 12a, 13a, so that the actuating element 14 does not move or move when actuated.
  • the control element 2 is at its lower end (see FIG. 2) arranged on the metal tube 4 element 19 pivotally mounted.
  • the The pivot axis runs transversely to the longitudinal axis of the control element 2.
  • FIG. 6 shows a representation corresponding to FIG. 3, but with two transducers 5 from those of the right one with respect to FIG. 6 transversely to the longitudinal axis and that with respect to FIG. 6 left transducer 5 are aligned in the direction of the longitudinal axis.
  • the left converter in Fig. 6 is supported with the lower and upper side on the housing 18.
  • the control element 2 is in addition to its ability to be given away by the element 19 along the Metal tube 4 displaceable by about 1-2 mm.
  • a third is not shown in FIG. 6 Converter 5, which is in a plane with the right converter 5 and perpendicular to this is aligned.
  • the sensor surfaces 6 are parallel or transverse to the longitudinal axis of the control element 2 arranged, that is in the three directions provided, in which the hand force should be recorded.
  • the control element 2 thus has three transducers 5 arranged perpendicular to one another which enable three-dimensional control.
  • Fig. 2 also shows one of a light emitter 20 and one Light receiver 21 formed light barrier which when gripping control element 2 emits an actuation signal by hand.
  • the electrical is zeroed Transducer signal.
  • the converter signal is consequently zero, regardless of which one exact unoccupied position is the unactuated actuating element 14.
  • control element 2 A simple but compact design of the control element 2 is This ensures that an additional flexible printed circuit board in the upper part of the Control element 2 is arranged. This enables inexpensive assembly and inserting the printed circuit board according to the inner contour of the control element 2.
