    Figure 5 Shows an adjusting device according to the invention with an eccentrically offset axis of rotation Figure 6 Shows an adjusting device according to the invention with a circular cross-section and an eccentric axis of rotation 11, 12 Figure 7-9 Shows the 3 positions according to Figure 4 in a perspective view of an operator gate.
    DESCRIPTION OF EMBODIMENT FORIVIVES Figure 1 shows an industrial truck 1 of the articulated forklift type according to the invention. The industrial truck 1 has a guide arm 2 and a platform 3 for carrying an operator standing on it. The industrial truck 1 also has an operator gate 4 which is designed according to the invention. The operator gate 4 is attached to the industrial truck 1 in a substantially vertical direction above the platform 3.
    The platform 3 is attached to a lower part of the industrial truck 1. The attachment to the industrial truck 1 takes place with a fastening portion 5 of the operator gate 4.
    The operator gate 4 also comprises a support portion 6. The operator gate 4 is preferably placed symmetrically on the industrial truck 1, but variants where the gate is moved horizontally via its attachment are conceivable. An attachment at different heights on the truck is also conceivable.
    The task of the operator gate is to support and protect the operator with the support portion 6 when traveling on the platform 3. The operator gate 4 is usually substantially U-shaped with two free ends 7, 8 constituting the support portion 6 but can of course have other similar shapes, such as a rectangular U .
    Alternatively, the operator gate consists of two independent arms, each with its own attachment portion 5. A suitable height for the operator gate 4 above the platform 10 is so that the operator gate arms are located substantially at hip height on an operator standing on the platform 5.
    It is also conceivable for an L-shaped operator gate to have only one free end 7, 8. Of course, it is conceivable for the operator gate 4 to consist of only the two arms, which in that case are individually attached to the truck at substantially the same level in vertically.
    On the ends 7, 8 of the arms of the operator gate 4 there are adjusting devices 9, 10.
    According to a preferred embodiment, the adjusting device 9, 10 is arranged on at least a partial portion of the support portion 6 of the operator gate.
    The adjusting device 9, 10 may preferably be arranged in parallel together on an operator gate with double support portions according to Figs. 2, 7 -9.
    Preferably, the adjusting device 9, 10 consists of plastic or rubber or some other relatively soft material which allows the operator to lean against it without major discomfort. It can be a cushion, but other designs are also conceivable, for example a thinner variant in the form of a plate, or a harder variant, without any inherent softness. When an operator leans against the counter-adjusting device 9, 10, an abutment takes place against it.
    According to the invention, the height of the adjusting device 9, 10 can be adjusted by moving the adjusting device 9, 10. The movement takes place preferably by turning the device. See Figures 3 and 4, where in a cross section of an adjusting device 9, 10 according to the invention it can be seen how the height of the device is varied by rotation. The change in height can also be studied in Figures 7 and 9. In this preferred example this is done by arranging the adjusting device 9, 10 rotatably suspended on the support portion of the operator gate, preferably via its projecting ends 7, 8. The axis of rotation 11, 12 is then preferably eccentrically placed seen in a section perpendicular to the axis of rotation 11 , 12 according to Figures 7 - 9, but is still on a longitudinal center line. Thereby seen in the same section a portion of the adjusting device 9, 10 which is longer than another opposite portion which can be seen in Figures 7 - 9. Due to the rotatability of the adjusting device the longer portion when rotating the adjusting device 9, 10, is arranged in a position where it points substantially vertically upwards. This mode is best suited for a longer operator. The adjusting device 9, 10 can be rotated so that said longer portion points substantially downwards. This mode is then more favorable for a shorter operator.
    The adjusting device 9, 10 is arranged to be able to be rotated between said positions 1 and 11, in order to be able to allow an adjustment of the surface of the adjusting device 9, 10 intended to abut or support an operator. The adjusting device 9, 10 is also arranged to be able to assume an intermediate position 11 where the said longer portion points in a downward direction, seen from the horizontal plane and in the same section as above.
    This position 11 is favorable for an operator who wants to take a more sedentary position against the combination of adjusting device 9, 10 and operator gate 4.
    In this case, the horizontal contact surface of the adjusting device is also adjusted and the operator gate 4 becomes narrower, see figure 2. The operator can optionally choose to adjust one or both adjusting devices 9, 10. They can be set independently of each other, see figure 2, 3 and figure 9. See also in this connection figure 4 which shows the adjusting device 9, 10 in different vertical positions for the abutment surface of the adjusting device 9, 10.
    According to a preferred embodiment, the position of the shaft can advantageously be designed so that the shaft is placed eccentrically both in a direction that runs longitudinally in the current section and in a direction that runs across the current section. That is, in the example shown in Figures 2 - 5, with a rectangular cross-section, the axis of rotation is offset both in width and in length, in a cross-section perpendicular to the axis of rotation. Due to this displacement an adjustment in both height and width of the operator gate 4 is obtained in an efficient manner, which can be seen in figure 2 and in figure 4. The adjusting device 9, 10 can be locked in any position I, ll, | | by means of a locking device. The locking device consists of variants known to those skilled in the art.
    The adjusting device 9, 10 can according to a preferred design be arranged so that the above positions I, 11, 11 are distinct by means of a locking device which is spring-loaded and has elements which lock the adjusting device 9, 10 in these positions. By distinct positions are meant fixed steps.
    Of course, the inventive concept is not limited to the above.
    According to one embodiment, the adjusting device 9, 10 can be steplessly adjustable.
    This is preferably done by the device being able to be locked in any position.
    According to a variant, the adjusting device 9, 10 is arranged with distinct positions I ll | but can also be locked between these modes.
    Of course, it is possible to arrange any number of distinct positions, such as two, four or five for example.
    Of course, the adjusting device 9, 10 can have different shapes seen in cross-section for the axis of rotation 11, 12. The rectangular shape shown in Figure 5 could, for example, be exchanged for a fl-shaped shape or some shape of a triangular shape. A circular cross-section is also conceivable, as shown in figure 6. The cross-section of the adjusting device 9, 10 can also be changed over the length of the support portion 6 to achieve a better adaptation to the body shape of the operator. Of course, the support portion 6 can also be arranged centered in the sense that the axis of rotation 11, 12 is substantially centered in the cross section of the adjusting device 9, 10, whereby the number of setting positions becomes smaller.
    Within the scope of the invention, a method for modifying an existing industrial truck 1 is also considered to exist. The method then comprises the following steps: modifying an operator gate 4 by mounting an adjusting device 9, 10 on the operator gate 4 so that it becomes adjustable - mounting of the operator gate 4 on the industrial truck 1 so that an industrial truck 1 with adjustable operator gate is obtained. The adjusting device 9, 10 in the method is of the type previously described.
    According to an alternative method, an industrial truck 1 which already has an operator gate is modified in one step as follows: - modification of an operator gate 4 already mounted on an industrial truck 1, by mounting an adjusting device 9, 10 on the operator gate 4 so that it becomes adjustable, so that an industrial truck 1 with an adjustable operator gate is obtained. Here, too, the year adjusting device 9, 10 of the type previously described.
    The invention as described thus consists of an industrial truck 1. Preferably, the invention consists of such a truck as shown in figure 1, which is a guide arm truck with mounted operator gate and platform 3.
    The meaning industrial truck 1 refers to trucks that are material handlers. It has a load handling section and a drive section. In the case of articulated forklifts, the load handling section usually does not have a stand, but can also have a stand, this type of truck is usually called a stacker. The load handling portion includes a pair of forks. Usually there are two forks but the pair of forks should be interpreted as one or more forks. The pair of forks can be raised and lowered to handle loads. The raising and lowering function is performed with the help of hydraulic pistons. The fork pair can sit on a fork carriage, but can also be designed so that a fork carriage is not needed, for example on a low-lift industrial truck 1. In some industrial trucks 1, the fork pair can be pushed sideways. 10 15 20 12 The drive section contains functions for propelling the truck. The drive section contains an energy source. The energy source is preferably a battery, but can also be of another kind, such as petrol, diesel, gas or the like.
    The drive section contains at least one drive motor. The drive motor is connected to one or more of the truck's wheels. There is usually a switch between the drive motor and the drive wheel.
    The drive motor is usually an electric motor.
    The drive section usually includes control means for operating the truck. These can consist of a link arm 2, a steering wheel, and the like. There are also means for maneuvering the load section, these can consist of means for lifting, lowering, tilting and lateral movement of the forks, there may also be means for changing the fork spread. The bodies can be levers, knob knobs, or the like. They can be individual for each function or several functions are gathered in the same body. When the industrial truck 1 moves, the drive section works.
    The present invention is intended to be applied to an industrial truck 1 to create an invention according to the justified claims.
