Abstract

A soil processing machine, in particular a soil compactor, comprises a control cabin (18) having at least one control cabin door (20) pivotably supported on a door frame (22) between a closed position and an open position, wherein a handle formation (48) for pivoting the control cabin door (20) between the closed position and the open position is provided on at least one control cabin door (20) on a door inside (53) facing a control cabin interior (51) in the closed position, further comprising a fixing arrangement (46) for fixing the control cabin door (20) in the open position, wherein the fixing arrangement (46) is operable by means of the handle formation (48) for releasing the control cabin door (20) fixed in the open position.

First claim

The invention claimed is:

1. Soil processing machine, comprising a control cabin having at least one control cabin door/window unit pivotably supported on a door/window frame between a closed position and an open position, wherein a handle formation for pivoting the control cabin door/window unit between the closed position and the open position is provided on at least one control cabin door/window unit on a door/window inside facing a control cabin interior in the closed position, further comprising a fixing arrangement for fixing the control cabin door/window unit in the open position, wherein the fixing arrangement is operable by the handle formation for releasing the control cabin door/window unit fixed in the open position, wherein the handle formation comprises a handle element which is adjustable between a rest position and an actuation position and, upon adjustment from the rest position to the actuation position, acts on the fixing arrangement for releasing the control cabin door/window unit fixed in the open position.

2. Soil processing machine according to claim 1 , wherein the fixing arrangement comprises a fixing member which is fixed with respect to the control cabin and, on the control cabin door/window unit in association with the fixing member, a counter-fixing member which is adjustable between a fixing position and a release position and which can be in or brought into fixing engagement with the fixing member for fixing the control cabin door/window unit in the open position.

3. Soil processing machine according to claim 2 , wherein the counter-fixing member is pretensioned into its release position and is releasable for adjustment into its release position by means of the handle formation.

4. Soil processing machine according to claim 1 , wherein the handle element is pivotable between the rest position and the actuation position, and/or wherein the handle element is pretensioned in its rest position, and/or wherein the handle element acts on the fixing arrangement via a coupling element.

5. Soil processing machine according to claim 4 , wherein the coupling element comprises a coupling slide, and wherein a coupling slide actuating section assigned to the coupling slide and acting on the coupling slide for actuating the fixing arrangement when adjusting the handle element in the direction of the actuating position is provided on the handle element.

6. Soil processing machine according to claim 2 , wherein the coupling element interacts with the counter-fixing member to adjust the latter between the fixing position and the release position and/or wherein the handle element acts on the fixing arrangement via a coupling element that is pretensioned in an acting preparation position.

7. Soil processing machine according to claim 2 , wherein the handle element is assigned a first pretensioning arrangement which pretensions it into its rest position, and wherein the counter-fixing member is assigned a second pretensioning arrangement which pretensions it into its release position and is effective independently of the first pretensioning arrangement.

8. Soil processing machine according to claim 1 , wherein the control cabin door/window unit is pivotally supported on a pivot connection side on the door/window frame about a pivot axis (A) and/or is lockable in the closed position by means of a locking formation with respect to the door/window frame on a locking side lying at a horizontal distance to the pivot connection side, and wherein the handle formation is arranged offset with respect to a horizontal door/window centre (M H ) lying between the pivot connection side and the locking side of the control cabin door/window unit in the direction of the pivot connection side.

9. Soil processing machine according to claim 2 , wherein the control cabin door/window unit is pivotally supported on a pivot connection side on the door/window frame about a pivot axis and/or is lockable in the closed position by means of a locking formation with respect to the door/window frame on a locking side lying at a horizontal distance to the pivot connection side, and wherein the handle formation is arranged offset with respect to a horizontal door/window centre lying between the pivot connection side and the locking side of the control cabin door/window unit in the direction of the pivot connection side, and wherein the counter-locking member is arranged offset in the region of the horizontal door/window centre (M H ) or with respect to the horizontal door/window centre (M H ) in the direction of the pivot connection side.

10. Soil processing machine according to claim 8 , wherein the locking formation comprises a door/window handle arranged offset with respect to the horizontal door/window centre (M H ) in the direction of the locking side and/or a door/window lock arranged offset with respect to the horizontal door/window centre (M H ) in the direction of the locking side.

11. Soil processing machine according to claim 1 , wherein the control cabin door/window unit has a door/window top and a door/window bottom lying at a vertical distance from the door/window top, and wherein the handle formation is arranged offset with respect to a vertical door/window centre (M V ) lying between the door/window top and the door/window bottom in the direction of the door/window top.

12. Soil processing machine according to claim 8 , wherein the control cabin door/window unit has a door/window top and a door/window bottom lying at a vertical distance from the door/window top, and wherein the handle formation is arranged offset with respect to a vertical door/window centre lying between the door/window top and the door/window bottom in the direction of the door/window top, wherein the locking formation is arranged offset in the region of the vertical door/window centre (M V ) or with respect to the vertical door/window centre (M V ) in the direction of the door/window bottom.

13. Soil processing machine according to claim 1 , wherein in the open position, the control cabin door/window unit is pivoted to the maximum extent out of the closed position, and/or wherein the control cabin door/window unit is pivotable between the closed position and the open position with a pivot angle of more than 90°.

14. Soil processing machine according to claim 1 , wherein an intermediate position holding formation is provided for holding the control cabin door/window unit in an intermediate position between the open position and the closed position.

15. Soil processing machine according to claim 14 , wherein the intermediate position holding formation comprises a pretensioning unit acting on the control cabin door/window unit in the direction of the open position and a releasable movement stop.

16. Soil processing machine according to claim 1 , wherein the control cabin door/window unit comprises a lower door/window part and an upper door/window part which is pivotable independently of the lower window/door part between the closed position and the open position and wherein the handle formation is provided on the upper door/window part.

17. Soil processing machine according to claim 6 wherein the coupling element interacts with the counter-fixing member to adjust the latter between the fixing position and the release position via at least one actuating element.

18. Soil processing machine according to claim 13 , wherein the control cabin door/window unit is pivotable between the closed position and the open position with a pivot angle of more than 150°.

19. Soil processing machine according to claim 18
