DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0047] FIG. 1 shows a perspective view of an operator's cabin 1 having a housing structure 2 surrounding a workplace for an operator. This housing structure 2 typically has an access door at its left and/or right side through which the operator can enter into or exit the operator's cabin. At its front side, the housing structure 2 typically has a mount 3 for a front windshield through which the operator can look during a performance of his operating work. When carrying out hazardous work in which rocks or parts of building to be removed can fall down onto the operator's cabin, it is necessary for the increase of the safety of the operator to protect the front side of the operator's cabin with a front grid 4. The same also applies to the roof section 6 of the operator's cabin 2 that can likewise have a cutout for a roof window. It is thus made possible for an operator sitting in the operator's cabin to have a particularly good view upward so that the performance of demanding work activities of the work machine, for example the removal of building parts by means of a demolition excavator, is also made possible. It is thus necessary to also reinforce the roof section with a roof grid 5 so that falling parts also here do not result in a danger to an operator located in the operator's cabin.

[0048] As already explained in the introductory part of the present invention, the permanent looking through the front grid 4 is tiring and additionally also reduces the visibility through the front windshield of the operator's cabin 2. It is therefore desirable for the front grid 4 to be removable on a performance of non-dangerous work that does not require the additional protection of the front grid 4. This is made possible in the present case by the articulated connection of the front grid to a rotary axle 7 that extends in the width direction X of the operator's cabin and that enables a pivot movement of the front grid 4 by approximately 270° so that the front grid 4 is placed on the upper side of the roof grid 5, as in the view shown at the bottom left in FIG. 1. An unobstructed view through the front windshield of the operator's cabin 2 is thereby made possible so that work can also be carried out without problem that requires a particularly good view and that is not dangerous.

[0049] The roof grid 5 itself is also pivotably arranged at the same rotary axle 7 that permits a pivoting of the front grid 4 onto the upper side of the roof grid 5. If namely a transport of the operator's cabin or of the work machine connected to the operator's cabin takes place, it is of great importance to reduce the total height of the work machine or of the operator's cabin. Care is thus taken on a loading of the work machine or of the operator's cabin that the transport height is minimized and fewer height restrictions have to be observed on the transport of the work machine or of the operator's cabin. The transport mode of the operator's cabin is shown here in the lower right image of FIG. 1. It can be recognized that, starting from the upper representation in which both grids 4, 5 are located in their protective positions, the roof grid 5 has been pivoted via the common rotary axle 7 in front of the front grid 4 located in the protective position. The height (Z direction in the coordinate system of FIG. 1) is thereby reduced so that the transport of the operator's cabin 1 or of the work machine connected thereto can be effected more simply. The change from the front visibility mode that is present in the lower left representation in FIG. 1 toward a transport mode that is shown in the lower right representation in FIG. 1 can accordingly be easily effected by the pivoting round of the grids into the respective position.

[0050] Even though it is not shown, the automatic traveling of the grids into the respective positions is also covered by the invention. A drive device can be provided for this purpose that moves the front grid 4 or the roof grid 5 out of their respective protective positions. The provision of a common axle or rotary or pivot axle for the two grids, that is the roof grid 5 and the front grid 4, accordingly enables a particularly simple implementation to achieve the advantages of the present invention.

[0051] FIG. 2 shows a further embodiment of the present invention in which, after a pivoting of the front grid 4 onto the upper side of the roof grid 5, the grids 4, 5 thus stacked on top of one another can be folded down toward the right side of the operator's cabin 2. The rotary axle of the front grid 4 can thus be established via a connection section to the roof grid 5, with the roof grid 5 itself having a rotary axle that extends in the longitudinal direction Y of the operator's cabin and that is fastened to the operator's cabin 2. It is used to pivot the two grids 4, 5 stacked on top of one another by approximately 270° from the roof section 6 of the operator's cabin 2 down to a right side section of the operator's cabin 2. It is thus also possible to reduce the structural height of the operator's cabin for a transport mode and in so doing to simultaneously improve the front visibility by a folding away of the front grid 4 onto the side of the roof grid 5 remote from the operator's cabin 2.

[0052] FIG. 3 shows a further embodiment of the present invention in which the front grid 4 is again pivoted onto the upper side of the roof grid 5 via a rotary axle extending in the width direction of the operator's cabin 2. In the configuration of the two grids 4, 5 stacked on top of one another, a parallelogram deflection now takes place in which the horizontal alignment of the two grids 4, 5 stacked on top of one another is not changed. It is thus possible to place the two grids 4, 5 into a reception location, for example a support surface or the like, provided behind the operator's cabin 2 so that both operating modes, the front visibility mode and the transport mode, can also be achieved here without a final removal of the two grids 4, 5 from the operator's cabin occurring in so doing.

[0053] FIG. 4 shows a further embodiment of the present invention in which the front grid 4 is again pivoted onto the upper side of the roof grid 5 via a rotary axle extending in the width direction. A parallelogram linkage of the two grids arranged on top of one another subsequently takes place so that they are now no longer arranged above a roof section of the operator's cabin. A pivoting toward a rear side of the operator's cabin 2 takes place from this state so that the two grids are now arranged approximately in parallel with the previously adopted protective position of the front grid at the rear side of the operator's cabin 2. This represented a particularly space-saving storage possibility of the two grids.

[0054] FIGS. 5 and 6 each show only one grid, with, in the event of the front grid 4 and the roof grid 5 being present, the kinematics of movement for both grids 4, 5 being identical. If the grid shown in FIG. 5 is considered as the front grid 4, it is located in its protective position in the left representation of FIG. 5. By a rotation by approximately 90° upward, the front grid 4 is now in an approximately horizontal alignment so that it is movable by a translatory movement or by a pushing into the region above the roof section 6 of the operator's cabin 2. If the grid is the front grid, FIG. 5 therefore shows the change from the protective position of the front grid 4 into the front visibility mode. If, in contrast, the grid shown in FIG. 5 is the roof grid 5, the change from the transport mode into the protective position of the roof grid 5 is shown.

[0055] FIG. 6 again shows a grid that has been displaced from the roof section 6 via a pushing movement to the front toward the operator's cabin and can be folded in front of the front side of the operator's cabin 2 by a downward folding with respect to a rotary axle that extends in the width direction of the operator's cabin 2 and that is arranged in the upper region or above the operator's cabin 2. For the front grid, this is the transition from the front visibility mode toward the protective position. If, however, the grid shown in FIG. 6 is the roof grid, it is the transition from the protective position toward a transport mode.

[0056] The movement of the two grids 4, 5 is identical in each of the FIGS. 5 and 6 so that only one grid has been shown for reasons of better clarity. However, the invention also covers the case that the operator's cabin only has one of the two grids.

[0057] FIG. 7 shows a further embodiment of the present invention using which, in a first step, now the roof grid 5 no longer remains in its protective position, but the roof grid 5 is rather pivoted in front of the front grid 4 via a pivot axle extending in the width direction of the operator's cabin. If the pivoting has taken place, a pivoting of the two grids 4, 5, that are now aligned in parallel with one another, can take place via a further rotary axle that likewise extends in the width direction of the operator's cabin 2 and is arranged in the lower region of the operator's cabin or below the operator's cabin so that the two grids arranged in parallel fold down away to the front and are preferably aligned horizontally. If they are in a state folded away down to the front, the two grids can be pushed into a reception space arranged beneath the operator's cabin. The kinematics of the two grid movements can, for example, take place by a first hinge connection of the roof grid and front grid 4 so that the roof grid 5 can be pivoted to the front side of the front grid 4. The front grid itself then has a pivot connection to the operator's cabin in the lower region so that the two grids 4, 5 aligned in parallel with one another can be pivoted away downward to the front together. The two grids can then be pushed via rails or a different sliding system into the reception space arranged beneath the operator's cabin.

[0058] FIG. 8 shows a further embodiment of the present invention in which the front grid 4 is again pivoted onto the upper side of the roof grid 5 via a rotary axle extending in the width direction of the operator's cabin 2. A further rotation of the two grids 4, 5 aligned in parallel by approximately 270° produces a lying alongside of the two grids at the rear side of the operator's cabin 2. The rotary axles can be executed, for example, by a hinge connection between the roof grid 5 and the front grid 4 and by a hinge connection between the roof grid 5 and the operator's cabin. It is also clear to the skilled person that fastening means can preferably be provided for a common pivoting of the two grids 4, 5, aligned in parallel with one another to prevent an uncontrolled pivoting of the front grid 4 away from the roof grid 5 on the placing onto the rear side of the operator's cabin 2.

[0059] FIG. 9 shows a further embodiment of the present invention, in which the front grid cannot, for instance, be placed onto the upper side of the roof grid 5 by a pivot movement by 270°, but is rather only folded away upward to the front by 90° in a first step. The rotary axle is here located in a front upper section of the operator's cabin 2 or is located above the operator's cabin 2 in the front region. If the front grid 4 is now aligned horizontally in a first step, a stacking of the front gird 4 on the roof grid 5 can take place via a one-dimensional translatory movement. The subsequent pivoting about of the two grids 4, 5 stacked on top of one another toward a rear side of the operator's cabin 2 then again takes place via a pivot connection of the roof grid 5 with the operator's cabin 2.

[0060] FIG. 10 shows a further embodiment of the present invention in which the front grid 4 is again pivoted onto the upper side of the roof grid 5 by 270° about a rotation via a rotary axle extending along a width direction of the operator's cabin 2. Differing from FIG. 9, no rotation of the two grids stacked on top of one another by 270° now takes place, but rather only by 90° so that the two grids aligned in parallel with one another can be pushed into a rear reception section at the rear side of the operator's cabin 2 by a subsequent one-dimensional translatory movement (that is directed approximately perpendicular downward).

[0061] FIG. 11 shows a further embodiment of the present invention, in which the two grids 4, 5 are not stored in a common reception space or in a parallel alignment with one another. The front grid 4 and the roof grid 5 can be seen in their respective protective positions on the left side of FIG. 11. Each grid is here pivoted away from its protective position via a rotary axle extending in parallel with the width direction of the drive cabin. The rotary axle of the front grid 4 here extends at the lower region or beneath the operator's cabin, with the rotary axle of the roof grid 5 extending at the rear upper region or above the operator's cabin. Each of the grids is here pivoted about 90° from its protective position and is traveled in a subsequent step below or behind the operator's cabin. The separate pivoting away of the respective grids from their protective positions is accordingly possible here without restrictions for the other grid being present.

[0062] FIG. 12 shows a further embodiment for moving the front grid 4 onto the upper side of the roof grid 5. In this respect, the front grid is pivoted about approximately 45° about a rotary axle extending in the upper region of the operator's cabin transversely to the operator's cabin, is then pushed upwardly away such that the front grid 4 is arranged remote from the roof grid 5, and is rotated downward by 45° so that is lies on the upper side of the roof grid 5. It is clear to the skilled person that the value of 45° is only of an exemplary nature and other angular values can also be used for a corresponding use of the idea. Only the folding movement, the subsequent one-dimensional displacement, and the subsequent folding down of the front grid are decisive in the present case.

[0063] FIG. 13 shows a further embodiment of the present invention in which each of the two grids 4, 5 is connected to the operator's cabin via a rail system. The rail system here extends from the roof section 6 and extends up to the front section of the operator's cabin 2. On the movement of a grid from its protective position, a curved movement along a slide or along the rails is made in two directions in this process. Provision can be made here that both the front grid 4 and the roof grid 5 comprise a separate rail pair or a separate rail for moving the associated grid.
