Definitions

  • the invention relates to an operating element for industrial trucks, preferably stacker vehicles, with a rotary handle for stepless actuation of a driving circuit and with a lifting circuit.
  • the object of the present invention is to provide a reliable and, in particular, ergonomic operating element of high stability for industrial trucks, preferably for a forklift truck, with a low outlay of means and costs, which enables a simultaneous triggering of several vehicle functions with one hand, without the need to to have to release the hand at any time from the control element and the same time serve as a handle for the driver during the driving movements of the truck.
  • the rotary handle is designed as a multi-function handle for one-handed operation simultaneously all steering independent functions of the truck and provided on its circumference in the range of movement of the thumb of the operator with a signal generator for stepless and / or finely graduated operation of the lifting circuit.
  • the ergonomic integration of the actuator to the lifting circuit directly into the control element for driving circuit allows simultaneous one-handed operation both and resulting superimposed Movements of hoist and truck, without any interruption of the simultaneous steering operation of the truck with the other hand.
  • the rotary handle when starting or braking and when cornering the truck can also be used as a handle and driver support without running the risk of affecting existing functional rules or unintentionally trigger new ones.
  • the signal generator is designed as a double-sided adjustable in the circumferential direction slider, which also facilitates the continuous operation of the Hubschalters.
  • the driving circuit and the lifting circuit are arranged opposite each other at both ends of the Drehgrif fes and equipped with potentiometers, which can be a particularly space-saving, compact design with a minimum of circuit complexity can be achieved.
  • An advantageous embodiment of the invention is characterized in that the potentiometer are independently rotatably integrated into the rotary handle, the potentiometer shaft of the driving circuit potentiometer with the rotary handle and the potentiometer of the Hubscchez potentiometer is spring-loaded with the slider spring-loaded, which in addition to the achievement short travel especially a stepless control is used.
  • the signal generator is arranged centrally of a circular segment-shaped recess of the rotary handle and provided with a radial positioning tongue, extending through the centric in the longitudinal axis of the rotary handle, the potentiometer shaft.
  • a rotary handle 1 is provided with a non-slip grip surface 2, which preferably extends over the entire circumference and the entire length of the rotary handle 1.
  • the gripping surface 2 is provided with a rough or ribbed and optionally rubberized coating or instead with a knurled surface structure.
  • a shaft shoulder 3 At one end of the rotary handle 1 is a shaft shoulder 3, in which an outer annular groove 4 is inserted. Centric in the shaft shoulder 3 is a as Inner square 5 trained blind hole introduced.
  • a bearing cup 8 is arranged by means of a ball bearing 7, which is designed for attachment to the truck at its outer diameter as a flange 9.
  • Ball bearing 7 and bearing cup 8 are secured by means of two retaining rings 10 and 11 against axial displacement, with an outer locking ring 10 is located in the outer annular groove 4 of the shaft shoulder 3, and an inner locking ring 11 is embedded in an inner annular groove 13 of the bearing cup 8.
  • the driving circuit 18 includes u. a. a potentiometer 15 with a potentiometer 16 and generates in a known manner via a pulse control driving signals, such as "FORWARD”, “STOP” and “REVERSE", for controlling at least one driving motor.
  • the potentiometer shaft 16 is formed as a square. It extends through a bore 17 of the lid 14 and is guided in the inner square 5 of the shaft shoulder 3.
  • the rotary handle 1 expands into a bearing shell 19 with an inner recess 20.
  • a spring-loaded ball catch 41 is arranged in the wall of the bearing shell 19 whose spring tension can be changed by means of a set screw 42.
  • the recess 20 is followed by a bearing seat 21, which merges into a longer blind hole 6.
  • the u. a. includes a potentiometer 25 with a potentiometer 26 and generates stroke signals, such as "LIFT”, "STOP” and "LOWER", for controlling at least one lifting motor in a known manner via a pulse control.
  • Driving circuit 18, lifting circuit 24, potentiometers 15 and 25, pulse controls and the driving and lifting motor are known, commercially available components and therefore not, or only schematically illustrated and described.
  • the potentiometer shaft 26 extends through the bore 23 of the bearing cap 22 over the entire length of the blind hole 6 and is end mounted in a bore 36 which is centrally inserted into the bottom of the blind hole 6. In this case, the potentiometer shaft 26 üOber over the entire length of the blind hole 6 as a square shaft and mounted in the bore 36 shaft end is concentric.
  • the potentiometer shaft 26 is guided in a bearing bush 27, which in turn is mounted by means of a ball bearing 28 arranged on the bearing seat 21. Before the bearing bush 27, the potentiometer shaft 26 is secured by a locking ring 29 against axial displacement.
  • a return spring designed as a spreading spring is arranged on the bearing bush 27, one end of which abuts against a stop 31 fixed in the bearing shell 19 and the other end bears against a driver 32 fastened in the bearing bush 27 (FIG. 1).
  • the previously mentioned potentiometer shaft 16 is spring loaded.
  • the rotary handle 1 is preferably cast, for example in aluminum casting.
  • the rotary handle 1 can also be made as a turned part.
  • a circular segment-shaped recess 34 is recessed in the region of the blind hole 6, preferably radially aligned with the bottom, in the periphery of the Drehgrif fes 1, a circular segment-shaped recess 34 is recessed.
  • a signal generator 35 is arranged, which is preferably designed as a slider with knurled surface and as shown in FIG. 3 is slightly wider than the circular segment-shaped recess 34, whereby the edge regions thus rest on the circumference of the rotary handle 1.
  • the signal generator 35 is provided with a radially extending into the blind hole 6 of the rotary handle 1 Stellzunge 38, in which a bore in the form of a mecanicvierkants 39 is inserted.
  • a bore in the form of a mecanicvierkants 39 is inserted.
  • the inner square 39 extends centrally in the longitudinal axis 40 of the rotary handle 1 formed as a square portion of the potentiometer 26.
  • the Stellzunge 38 of the signal generator 35 is secured on its underside with respect to the potentiometer 26 in a known manner with a locking screw, not shown.
  • the rotary handle 1 By turning the rotary handle 1 either left or right-preferably by means of the operator's right hand-the potentiometer shaft 16 of the drive switch 18 is rotated, thereby generating varying voltage values which are used in the pulse control to control the drive motor after their processing. Since the other, preferably left hand is claimed for steering the forklift truck, it was previously only possible to perform a superimposed hoist movement while driving to the generation of the driving signals.
  • the spring-loaded ball catch 41 can be selectively brought out of engagement with the locking recesses 43 by means of the adjusting screw 42 or other mechanical means, whereby an absolutely continuous displacement of the signal generator 35 is made possible. This can also be done in a simple manner in the form that a rest position, not shown, is provided, in which the spring-loaded ball catch 41 for the purpose of relieving and releasing their detent ball of their rest position can optionally be completely dug.
  • the operator can in an emergency by simply releasing the rotary handle 1 and / or the signal generator 35, the initiated movements individually or collectively bring to a standstill.
  • the signal generator 35 is automatically returned to its zero position 37, since the force of the return spring is far greater than that of the ball catch 41 and the latter thus picking up.
  • operating errors are excluded in principle completely and the operator can fully concentrate on the initiated by him movements of his vehicle, and the loading and unloading.
  • the rotary handle 1 during driving movements - especially when accelerating and decelerating and when cornering - the truck by the driver in a kind of additional function as a stabilizing handle or as a side support can be used.
