Operating arrangement of a mobile working machine

The invention relates to a control arrangement of a mobile machine, in particular an industrial truck, with a multifunction lever for operating various functions of the machine.

Mobile machines, in particular industrial trucks, such as forklifts, Reach truck or turret trucks, often with a multi-function lever - also called joystick - to control various functions of the machine equipped. When industrial trucks are using the multi-function lever, for example, controlled following functions: vertical movement of a load pickup means, Tilting movement of a mast, horizontal displacement of Load receiving means, driving the truck, horn. For this purpose, the Multifunction lever itself can be moved in several directions. In addition to the located multifunction lever different controls that is independent of itself can be actuated movement of the multi-function lever.

In known control arrangements of the multi-function lever is releasably attached to the mobile machine fixed. In terms of size and shape is the Multifunction lever matched to an operator with a medium hand. This means that the multi-function lever for operating personnel with particular small or very large hands is not ergonomically optimized. This may result in operating errors, for example due to accelerated fatigue concerned operator lead.

The present invention is therefore the object of providing a control arrangement to provide a multi-function lever available to operators with different sized hands allows a safe operation of the machine.

This object is achieved in that at least two different multi-function lever are provided, either on the Working machine can be fixed, and that a fastening device for releasably Attachment is exactly provided a multifunction lever on the work machine.

To be able to multi-function lever releasably attach, has the working machine a defined interface, with which the mechanical and electrical Compound is prepared. The various multi-function lever are in ergonomic point individually adapted to the respective operator.

This is done for example by the fact that the different differ multifunction lever in size. Each operator may make a Multifunction lever obtained which is adjusted to the individual hand size.

Likewise advantageous is if the different multi-function lever in the different form. Due to the different design also takes place Adjustment of the ergonomics of the multifunction lever to the operator.

According to another expedient embodiment differ different multi-function lever in color. The different colors makes it easier for different operators, each their own Multi-function lever to recognize.

Particular advantages result if the multifunction lever integrated have storage element. In the storage element so that data can be stored be transmitted to a vehicle computer of the working machine, when the multi-function lever on the interface provided with the Working machine is connected.

It is likewise advantageous if the storage element a represents access credential to an operator. It recognizes a Computer work machine each operator based on their individual Multifunction lever. The multi-function lever can thus other means of identification replace such as smart cards or PIN input device.

Similarly, in the memory element parameters to configure the Working machine to be stored. This may be for example, a Seat adjustment for driver's seat, a user profile or data for other personalized features of the machine act.

Further advantages and details of the invention will become apparent in the schematic figures illustrated embodiment explained in more detail. It shows<dl tsize="7" compact="compact"><dt>figure 1</dt><dd>an operating arrangement of the invention,</dd><dt>figure 2</dt><dd>a multi-function lever for an operator with a large hand,</dd><dt>figure 3</dt><dd>a multi-function lever for an operator with a small hand.</dd></dl>

1 shows an operating arrangement according to the invention is shown, in which a Multifunction lever 1 releasably attachable to an arm rest 2 of a work machine is. The armrest 2 and the multi-function lever 1 point for this part of a defined Fastening device 3 that the mechanical and the electrical connection establishes between multifunction lever 1 and the driven machine. As mechanical Connection in the present embodiment, a bayonet lock provided the electrical connection is via the multi-function lever 1 provided plug-in contacts 4, which engage in bushes 5 on the work machine.

When assembled, the multi-function lever 1 can together with the at Working machine arranged component of the fastening device 3 a are pivoted and the longitudinal axis about a transverse axis of the working machine, wherein these movements are detected by means arranged in the working machine sensors and are converted into control signals. In addition to the multi-function lever various controls 6 arranged whose signals via the interface 3 to Working machine are transferred.

Figures 2 and 3 show two different multi-function lever 1a or 1b can be optionally attached to the same armrest. 2 The multi-function lever 1a and 1b differ in particular in terms of their size and are individually two to the different sized hands 7a, 7b operators Voted. In addition, the multi-function lever possess 1a, 1b integrated Memory elements, each as access credentials for serve operator and an individual configuring of selected Vehicle parameters allow.

The different, can be fastened to the same armrest 2 multi-function lever can, as described above, in the size, but also in the shaping and the color difference. In addition to individual adaptation of ergonomics can thereby also the risk of unintentional confounding the Multi-function lever can be minimized.
