Abstract

A dirt pick-up device for a floor cleaner is provided, including a carrying part fixable to the floor cleaner and a holding part releasably connectable to the carrying part with a suction strip held on the holding part, the carrying part and the holding part locked to each other by a locking device, the dirt pick-up device including an actuating element which is transferable from an unactuated position to an actuated position for transferring the locking device to an unlocked position in which the holding part is releasable from the carrying part. The dirt pick-up device can include or form a grip element held on at least one of the holding part and the suction strip, and in the unactuated position, the actuating element can be at a greater distance from the grip element than in the actuated position. A floor cleaner with a dirt pick-up device is also provided.

First claim

The invention claimed is:

1. A dirt pick-up device for a floor cleaner, comprising a carrying part fixed or fixable to the floor cleaner and a holding part releasably connectable to the carrying part with a suction strip held on the holding part, the carrying part and the holding part being locked to each other by a locking device assuming a locked position, the dirt pick-up device comprising an actuating element which is transferable from an unactuated position to an actuated position for transferring the locking device to an unlocked position in which the holding part is releasable from the carrying part, wherein the dirt pick-up device comprises or forms a grip element held on at least one of the holding part and the suction strip, and wherein in the unactuated position the actuating element is at a greater distance from the grip element than in the actuated position in which an operator is able to grasp the grip element.

2. The dirt pick-up device in accordance with claim 1 , wherein the grip element is configured as bow-shaped handle, handle bar, grip edge, olive handle, knob grip, grip eyelet or recessed grip.

3. The dirt pick-up device in accordance with claim 1 , wherein the grip element is formed in one piece with the holding part.

4. The dirt pick-up device in accordance with claim 1 , wherein the actuating element is of bow-shaped configuration.

5. The dirt pick-up device in accordance with claim 1 , wherein the actuating element has a contour identical or similar to the contour of the grip element and in the actuated position is positionable against the grip element.

6. The dirt pick-up device in accordance with claim 1 , wherein at least one of the grip element and the actuating element define a reach-through area for an operator to reach through.

7. The dirt pick-up device in accordance with claim 1 , wherein in an operating position of the dirt pick-up device, the actuating element is arranged above the grip element.

8. The dirt pick-up device in accordance with claim 1 , wherein the actuating element is pretensioned in the actuated position in the direction of the unactuated position.

9. The dirt pick-up device in accordance with claim 1 , wherein the locking device, on the one hand, and the grip element and the actuating element, on the other hand, are arranged on opposite sides of the holding part.

10. The dirt pick-up device in accordance with claim 1 , wherein the actuating element passes through the holding part with at least one section at at least one through-opening and is connected to at least one locking element of the locking device, and wherein the at least one section is movable in the at least one through-opening to transfer the actuating element from the unactuated position to the actuated position and vice versa.

11. The dirt pick-up device in accordance with claim 1 , wherein the locking device is configured as at least one of a latching device and a clamping device.

12. The dirt pick-up device in accordance with claim 1 , wherein the locking device comprises at least one first locking element arranged on the holding part and comprises at least one second locking element arranged on the carrying part, which interact in the locked position and by actuation of the actuating element are transferable to the unlocked position.

13. The dirt pick-up device in accordance with claim 12 , wherein the at least one first locking element and the at least one second locking element comprise a projection and a stop element for the latter, the projection engaging behind the stop element in the locked position to form a rear engagement of the projection with the stop element, with the rear engagement being released in the unlocked position.

14. The dirt pick-up device in accordance with claim 13 , wherein the at least one projection comprises at least one slide-on surface for the stop element, along which the latter slides when connecting the holding part to the carrying part and/or releasing the holding part from the carrying part.

15. The dirt pick-up device in accordance with claim 13 , wherein the at least one first locking element comprises or forms the at least one stop element, and wherein the at least one second locking element comprises or forms the at least one projection.

16. The dirt pick-up device in accordance with claim 13 , wherein the at least one projection is formed in one piece with the carrying part or with the holding part.

17. The dirt pick-up device in accordance with claim 12 , wherein the locking device comprises two first locking elements and two second locking elements, the first locking elements and the second locking elements being arranged, in each case, at a distance from each other on the holding part and on the carrying part, respectively.

18. The dirt pick-up device in accordance with claim 12 , wherein the at least one first locking element and the at least one second locking element are pretensioned in the unlocked position relative to each other in the direction of the locked position.

19. The dirt pick-up device in accordance with claim 12 , wherein the locking device has a locking space in which the locking elements are arranged in the connected state of the carrying part and the holding part, the locking space being delimited by walls formed by the carrying part and by the holding part.

20. The dirt pick-up device in accordance with claim 12 , wherein the actuating element is connected in one piece to at least one first locking element.

21. The dirt pick-up device in accordance with claim 12 , wherein the at least one first locking element comprises or forms the actuating element or vice versa.

22. The dirt pick-up device in accordance with claim 12 , wherein the dirt pick-up device comprises a deformation element which comprises or forms the at least one first locking element and is supported on at least one of the holding part and the suction strip, and wherein the at least one first locking element is transferable from the locked position to the unlocked position with elastic deformation of the deformation element and is transferable from the unlocked position to the locked position with return deformation.

23. The dirt pick-up device in accordance with claim 22 , wherein the deformation element comprises or forms the actuating element, the deformation element being elastically deformable by the application of force to the actuating element in order to transfer the latter from the unactuated position to the actuated position, and the actuating element being transferable from the actuated position to the unactuated position with return deformation of the deformation element.

24. The dirt pick-up device in accordance with claim 22 , wherein the deformation element is a wire or a rod.

25. The dirt pick-up device in accordance with claim 22 , wherein the deformation element comprises two segments arranged at an angle to each other and connected to each other at an apex of the angle, with sections thereof engaging a locking space of the locking device in which the locking elements are arranged, the segments being approachable towards each other and spreadable relative to each other with the angle thereby being reduced and increased, respectively.

26. The dirt pick-up device in accordance with claim 1 , wherein the locking device is at least one of self-locking and self-unlocking, the holding part and the carrying part being connectable to each other in a direction o
