Definitions

  • the invention relates to a truck with a multi-function lever, which at least one lever pivotable about a first axis and at least one having the lever arranged operating element, wherein by pivoting the Levers about the first axis and by pivoting the control element by a second Axle at least one function of the truck is controllable, and wherein the truck a movable in the vertical direction load receiving device and the vertical movement of the load receiving device by pivoting the lever is controllable about the first axis and the truck one by one horizontal tilt axis inclinable load bearing device and tilting the load receiving device by pivoting the operating element to the second Axis is controllable.
  • Multi-function lever of the type mentioned in forklifts are usually for Control of various functions of a load-bearing device used.
  • the load receiving device in the vertical direction up and be moved.
  • the load bearing device be inclined about a horizontal axis. It is also known that Load-bearing device horizontally displaceable in one or two directions perform.
  • Multi-function levers are used to engage an operator successive or simultaneous operation of various functions of the To allow for overhead goods, without embracing between different require conventional control lever.
  • a single multi-function lever So at least two functions of the truck can be controlled.
  • Multifunction levers In order to minimize the risk of incorrect operation of the truck, is sought, the required operating direction of the lever or the Control as functional as possible to the controlled function of the To arrange the truck. Another goal in the design of Multifunction levers is to sequentially or simultaneously actuate the to enable various functions in an ergonomically advantageous manner. Known multi-function levers can not meet the above objectives completely satisfactory.
  • the present invention is therefore based on the object, a truck of initially provided with a multi-function lever, which also in a driver's seat assembly in which one sitting in the driver's seat Operator looks at the load handling device, the most important functions in ergonomically advantageous functional logic are controlled.
  • the vertical movement of the load handling device is controllable by pivoting the lever about the first axis.
  • the lifting and lowering the load receiving device is thus by the operator by moving the entire hand controllable.
  • the tilting of the load bearing device is through Pivoting the control element about the second axis controllable. Tending the Load bearing device is thus of the operator with the index finger of the Handle grasping hand controllable.
  • the operating element with the index finger of a Handle is gripping hand operated.
  • the index finger is a sensitive operation of the control possible, so that the control element also used to generate multi-level or stepless control signals can.
  • a functional logical and the usual convention corresponding assignment of Movement directions of lever and load bearing device is present when a Swiveling the lever towards the load handling device to a vertical Downward movement of the load receiving device is associated with a pivoting the lever in the direction away from the load bearing device a vertical Upward movement of the load receiving device is assigned.
  • This arrangement is particularly useful when the second axis in is arranged substantially parallel to the horizontal tilt axis and one Pivoting movement of the operating element a tilting movement of the Load receiving device is assigned in the appropriate direction.
  • a third function of the truck is controllable, wherein the third axis in is arranged substantially perpendicular to the first axis.
  • To control the third Function moves the operator thus the lever from their view to the left or right.
  • the invention is upon actuation of the Operating element in response to the tilt angle of the operating element a certain tilting speed of the load receiving device can be specified.
  • a neutral position and the control element has Means for generating a restoring force in the direction of the neutral position. If the operator does not operate the control, this ensures that the control is in neutral position and no tilting movement of the Load-receiving device takes place.
  • certain setpoint for the inclination of the load receiving device upon actuation of the Operating element in response to the tilt angle of the operating lever certain setpoint for the inclination of the load receiving device can be specified.
  • a means for detecting the actual inclination of the Load-receiving device provided.
  • an actuator For example, a hydraulic cylinder, for generating a tilting movement of Lifting means provided in a control loop in response to the Setpoint for the inclination and the actual inclination is controlled.
  • the actuator is actuated until the actual Slope corresponds to the specified value.
  • the control element no means for generating a restoring force having. If the operator does not change the position of the operating element, the control remains in its respective position, so that the setpoint for the inclination remains unchanged.
  • Additional functions are controllable with the multi-function lever, if at the Lever at least one switching element is arranged, when actuated by means of the operating element instead of tilting the load receiving device another Function of the truck is controllable.
  • the additional features For example, a load gripper or a feed device, depending on the be defined special design of the truck.
  • the switching element is only effectively operable when the operating element is in a neutral position. This will ensure that by operating the switching element no wrong operation with the Control element controllable functions can take place.
  • the truck according to Figure 1 has a vehicle frame 1, with two load-side drive wheels 2 and a rear wheel 3 stands up on a road.
  • a driver's seat 4 and a steering wheel 10 are arranged such a seated on the driver's seat 4 operator on a Load-receiving device 5 looks.
  • the load receiving device 5 as a fork executed.
  • the load receiving device 5 is by means of a mast 6 mounted vertically movable on the vehicle frame 1. Together with the Mast 6, the load receiving device 5 relative to the vehicle frame. 1 be inclined about a horizontal axis 7.
  • Also known are industrial trucks, where a mast is rigidly attached to the vehicle frame, and the Load-receiving device is tilted relative to the mast.
  • a Side slide are provided, with the load receiving device 5 relative to the mast 6 in the transverse direction of the truck, ie in the direction of the axis 7, is displaceable.
  • the multi-function lever 8 is located at the front end of one beside the driver's seat 4 arranged armrest 9, so that it by the operator with the right hand can be operated.
  • FIG. 2 shows the multi-function lever 8 according to FIG. 1 in the viewing direction A.
  • Multifunction lever 8 has as a base body on the armrest 9 movable attached lever 11.
  • the lever 11 is about a first, in the transverse direction of the Truck extending axle 12 pivotally, bringing the vertical movement the load-receiving device 5 can be controlled. If the lever 11 after the front, pivoted in the direction 12a, the load receiving device 5 moves to below, upon actuation of the lever 11 in the direction 12b upwards.
  • an operating element 13 is arranged on the lever 11, the order an axis 14 can be pivoted. At least when the lever 11 is at rest the axes 12 and 14 are parallel to each other.
  • the control element can the Tilting of the load bearing device 5 are controlled about the horizontal axis 7, wherein the axes 7 and 14 are substantially parallel to each other.
  • the lever 11 is additionally pivotable about a horizontal axis 15, located in the extends substantially in the longitudinal direction of the truck.
  • a side shifter By panning the Levers about the axis 15, a side shifter in functional logical assignment of Actuating direction to be controlled.
  • another switching element 16 is arranged such that it can be operated simultaneously with the control element 13.
  • the switching element 16 Upon actuation of the Switching element 16 is the operating element 13 instead of tilting the Load receiving device 5 assigned a different function of the truck.
