  • a between the sprockets 31 and 53 effective arretierendes torque can be transmitted to the spar 23 via the holding part 32 and the metal sheet 50.
  • the metal sheet 50 serves both for biasing the sprockets 31 and 53 relative to each other and for torque transmission from the locking body 51 to the handle device 19th
  • the locking of the handle device 19 can be solved by the user on the lever 43 a facing away from the base 12, in the longitudinal direction of the handle device 19 aligned actuating force on the trigger member 48 exerts.
  • the actuating force is transmitted via the tie rod 41 on the crosspiece 44, against the bias of the coil spring 46th
  • the crosspiece 44 moves in the axial direction of the tie rod 41, which is supported on the holding part 32 and does not bend. This has the consequence that deflected by the positive guide 65, the actuating force by 90 ° in an axial release force and the force deflecting element 55 is displaced in the axial direction relative to the holding part 32. As a result, the sprockets 31 and 53 are disengaged against the bias of the metal sheet 50 ( FIG. 4B ).
  • the gripping device 19 is thereby unlocked from the base 12, because no locking device is arranged on the hinge 21, and it can be pivoted about the pivot axis 22.
  • the plurality of protrusions 30 and 52 allow the gripping device 19 to be locked in a variety of angular positions relative to the base 12, so that it can be adapted to the needs of the respective user in a user-friendly manner.
  • the user lets the operating force on the handle element 42 after. Due to the bias of the coil spring 46, the trigger member 48 moves back to its original position. Under the action of the positive guide 65 and the supplementary bias of the metal sheet 50, the sprockets 31 and 53 are transferred again relative to each other in the axial direction from the release position to the locking position, and can again engage each other.
  • the above-described mechanism for locking and unlocking the handle 19 on the base 12 is manageable in a user-friendly manner.
  • the required to solve the locking actuator force can be applied to the lever 43 and thus on the already operated by the user handle 25 without the user must change his posture for this purpose.
  • the actuating device 67 allows the deflection of the actuating force acting in the longitudinal direction of the handle device 19 in an axial release force for transferring the sprockets 31 and 53 from the locking position to the release position.
  • the space can be saved on the base 12, which makes it possible to position the reservoir 18 on the base 12.
  • the positioning of the reservoir 18 on the base 12 is advantageous because it does not require the reservoir 18 to be held on the handle 19, which reduces the load on a user on the handle 19. At the same time, the contact pressure of the cleaning brush 16 can be increased to the floor surface to be cleaned.
  • the axial engagement between the sprockets 31 and 53 is advantageous because almost complete zero backlash of the handle device 19 on the base 12 can be achieved.
  • the handle 25 has an actuating element for the drive device in the form of an actuating lever 69, with which a switching element, not shown, can be actuated.
  • actuating element for the drive device in the form of an actuating lever 69, with which a switching element, not shown, can be actuated.
  • cable 68 connected.
  • the cable 68 is guided, and it emerges at the base 12 facing the end of the handle Holmes 24 from an outlet opening 70.
  • the left handle bar 24 is held on the base 12 by means of a holding part 71, which corresponds to the holding part 32 for the right handle bar 23, as well as by means of a bearing part 71 cooperating with the bearing part 72.
  • the bearing part 72 corresponds to the bearing part 27.
  • a cover 35 corresponding cover 73 is in FIG. 5 as well as a left roll 74, so that in FIG. 5 the view is released on a U-shaped opening 75 of the holding part 71st
  • the cable 68 can enter into the cup-shaped space formed by the bearing part 72. From the bearing part 72, the cable 68 can enter through a formed in the base 12 further opening 76 in a channel portion 77 on the bottom 13 of the base 12 ( FIG. 6 ). Out of the channel section 77, the cable 68 may enter the motor housing 17 through an aperture 78 (not shown) where it is connected to the drive means.
  • the holding part 71 engages over the bearing part 72 loosely and together with it forms a housing 79 for protecting the cable 68.
  • a channel 80 for the passage of the cable 68 is formed with a first, formed by the handle device 19 and especially its handle bar 24, Kanatabites 81 and the second channel section 77.
  • the channel sections 77 and 81 go to the joint 21 by means of Holding parts 71 and the bearing part 72 into each other.
  • the cable 68 is reliably protected from dirt and cleaning fluid.
  • the single-disk machine 10 has a securing device 82 for securing the grip device 19 against pivoting about the pivot axis 22 (FIG. FIGS. 7 to 8B ).
  • the securing device 82 is integrated in the left hinge 21, and it includes an am
  • the guide body 83 has an obliquely oriented to the horizontal guide 84 is formed for a first securing member 85 of the securing device 82.
  • the first securing member 85 is configured in the form of a longitudinally along the guide 84 alone under the influence of gravity sliding locking pin 86.
  • the locking pin 86 may cooperate with a second securing member 87 of the securing device 82.
  • the second securing member 87 is formed on an edge 88 of the holding part 71 U-shaped recess 89th
  • the securing device 82 By means of the securing device 82 it is prevented that when the gripping device 19 assumes the parking position and the single-disk machine 10 is turned off with vertically oriented gripping device 19 ( FIGS. 5 and 6 ), the base 12 unintentionally flips in the direction of the footprint. It could happen that a user inadvertently actuates the actuating device 67 in this position of the single-disc machine 10 and thereby transfers the locking device 54 into the release position. In this case, the securing members 85 and 87 occupy the securing position because the guide 84 is aligned obliquely downward toward the bottom surface, ie Figure 8A should be viewed rotated by 90 ° in a clockwise direction.
  • the pivoting of the base 12 relative to the handle device 19 is blocked by the securing device 82. Even with unintentional release of the lock can be prevented that the base 12 pivots and tilts a user eg on the foot.
