On bottom, remain on pull bar 41 perpendicular to the axis limited by pull bar and perpendicular to the lateral member 44 of pivot axis 22 orientation.Only shown in Figure 2 to be used as the helical spring 46(of compression spring) holding member 32 is pre-tensioner relatively by lateral member 44 and then pull bar 41 for the pre-tensioning element 45 of form, and relative motion on the direction of handle element 42 is pre-tensioner or rather.Helical spring 46 can be supported on the shoulder 47 of holding member 32.
Pull bar 41, handle element 42 and lateral member less than 44 are also referred to as trigger element 48.
Face support unit 27 ground, holding member 32 is fixed with in plate shape, with the element 49(Connection Element 491 of two Connection Elements apart from pivot axis 22 some spacing shown in Fig. 4 A and Fig. 4 B).Thus, the free end that the element 49 in plate shape can not fixed with it bounces on the axial direction of pivot axis 22.Should especially be designed to sheet metal 50 by element in plate shape.
On sheet metal 50, face the lock body 51 that ring gear 31 ground maintains other, this lock body and lock body 28 as one man design.Therefore, lock body 51 is be provided with a large amount of ring gear 53 of protruding 52 equally.Projection 52 faces ring gear 31 and they can embed in a lot of state with the projection 30 of ring gear.Lock body 28 forms locking device 54 together with 51, for door handle device 19 is locked in pedestal 12.
In addition, on sheet metal 50, power deflecting element 55 remains on the side facing holding member 32 of this sheet metal, keeps more precisely by for the unshowned in the accompanying drawings Connection Element remained on by ring gear 53 on sheet metal 50.Power deflecting element 55 comprise abut on sheet metal 50 in the first section 56 of plate shape, by this section be parallel to pivot axis 22 ground stretch out two as one man design and the lateral sectors 59 being respectively provided with the elongated hole 57 and 58 of inclination in other words 60.The penetrating part 61 in shape of slotting that lateral sectors 59 and 60 only runs through interlocking holding member 32 in locking manner with travelling ground approximate shapes slightly in other words 62.This causes and can be bearing on holding member 32 with passing along pivot axis 22 by power deflecting element 55, and wherein, the edge of penetrating part 61 and 62 can directed force deflecting element 55.
Its end shape opposite each other of lateral member 44 travelling to be embedded in elongated hole 57 and 58 with some in locking manner, thus trigger element 48 and power deflecting element 55 can be supported each other with passing.
Elongated hole 57 and 58 is the guides of the guide rail 63 and 64 defined for lateral member 44, and they are obliquely relative to the axis ground orientation that pivot axis 22 and favouring is limited by pull bar 41.Thus, power deflecting element 55 comprises the mandatory guidance portion 65 for trigger element 48, and it is especially with the form of the chute guide portion of the elongated hole 57 and 58 by tilting.
Sheet metal 50 is formed ring gear 31 and 53 pre-tensioned pre-tensioning element 66 in the axial direction relative to each other.Just produce pre-tensioner voluntarily when ring gear 31 and 53 embeds each other as in Figure 4 A.
Trigger element 48, helical spring 46, power deflecting element 55 and sheet metal 50 together form manipulation device 67, so that by the lock release of door handle device 19 on pedestal 12.The locking of door handle device 19 on pedestal 12 is run as follows by the unblock of pedestal 12 in other words:
In the normal operation of single disc-type machine 10, ring gear 31 and 53 is in the axis embedding of pinning each other, thus makes they and locking device 54 occupy lock-out state.Because ring gear 31 on pedestal 12 and ring gear 53 respectively keep in anti-relative rotation on handle beam 23, door handle device 19 can not carry out pivotable around pivot axis 22.In the case, door handle device 19 is close to and is locked on pedestal 12 without play, because ring gear 31 and 53 embeds each other along the whole periphery of pivot axis 22.In addition, make locking especially reliably become possibility thus because the projection 30 of about 30 to about 60 of ring gear 31 and 53 in other words 52 embedding whole interlaced with each other.
Transverse to pivot axis 22 and the direction transverse to beam 23, be arranged in (Fig. 4 A and Fig. 4 B) in the accommodation section 651 be formed in holding member 32 sheet metal 50 positive.By positive and Connection Element 491 and unshowned Connection Element can via holding member 32 and sheet metal 50 by the transmission of torque of locking that works between ring gear 31 and 53 on beam 23.
Thus, sheet metal 50 is not only for ring gear 31 and 53 relative to each other pre-tensioner but also for from lock body 51 to the transmission of torque on door handle device 19.
The locking of door handle device 19 can get loose in the following way, that is, user on lever 43 by pointed to leaving by pedestal 12, on the longitudinal direction of door handle device 19, the steering force of orientation is applied on trigger element 48.Steering force is passed in lateral member 44 by pull bar 41, overcomes the pre-tensioner of helical spring 46 or rather.
Lateral member 44 is moved on the axial direction of pull bar 41, and this pull bar to be supported on holding member 32 and not to bend.This results through mandatory guidance portion 65 and steering force is deflected to axial release force with 90 ° and power deflecting element 55 is passed relative to holding member 32 in the axial direction.Thus, ring gear 31 and 53 overcomes pre-tensioner disengaging embedding (Fig. 4 B) of sheet metal 50.Door handle device 19 unlocks with pedestal 12 thus, because do not arrange locking device on joint 21, and this door handle device can carry out pivotable around pivot axis 22.A large amount of protruding 30 and 52 make door handle device 19 become possibility about pedestal 12 locking under a lot of angle state, thus make this door handle device can user adaptive with the demand of corresponding user with open arms.
In order to be relocked by locking device 54, user reduces the steering force on handle element 42.Pre-tensioner based on helical spring 46, trigger element 48 motion is got back in its original state.Effect in mandatory guidance portion 65 and sheet metal 50 supplement pre-tensioner under, ring gear 31 and 53 relative to each other in axial direction again to be transferred to lock-out state from the state of getting loose and again can be reached embedding each other.
Mechanical device for the door handle device 19 of the locking and unlocking on pedestal 12 described above can operate in the mode of user close friend.Can execute cloth on lever 43 and then execute the operating portion 25 that cloth operating originally by user for the steering force got loose needed for locking, and user need not change its body gesture for this reason.Manipulation device 67 makes the steering force that works on the longitudinal direction of door handle device 19 become possibility, for being transferred to the state of getting loose from lock-out state by ring gear 31 and 53 to the deflection of axial release force.Therefore, do not need to be provided with manipulation device with it pedestal 12, to make ring gear 31 and 53 axially-movable relative to each other.Thus, pedestal 12 can save space, this space makes reservoir vessel 18 be positioned on pedestal 12 becomes possibility.The location of reservoir vessel 18 on pedestal 12 is favourable, because reservoir vessel 18 does not need to remain on door handle device 19 thus, it reduces the load for user on door handle device 19.Cleaning brush 16 can be improved to the squeeze pressure in floor to be cleaned simultaneously.
As already mentioned, it is favourable that the axis between ring gear 31 and 53 embeds because can realize thus door handle device 19 on pedestal 12 almost completely without travelling.
In the region in the joint 21 in left side, do not have to arrange the locking device being used for door handle device.Thus, saved space at joint 21 place and cable 68 has been threaded to unshowned drive unit from operating portion 25.Operating portion 25 have for drive unit, with the operating element of actuating linkage 69 form, utilize this actuating linkage can handle unshowned switch element.The cable 68 only illustrated in fig. 5 and fig. is connected on this switch element section.In the handle beam 24 in left side forming hollow body, guide cable, and cable is gone out from exit opening 70 on the end facing pedestal 12 of handle beam 24.
Handle beam 24 is by the corresponding holding member 71 of the holding member 32 to handle beam 23 and remain on pedestal 12 by with the coefficient support unit 72 of holding member 71.Support unit 72 is corresponding to support unit 27.The covering device 73 corresponding with covering device 35 is same in Figure 5 leaves a blank as the roller 74 in left side, thus can see the penetrating part 75 taken the shape of the letter U of holding member 71 in Figure 5.
Cable 68 can enter in the space in service plate shape formed by support unit 72 through penetrating part 75.Cable 68 out can be entered in the channel section 77 of the bottom surface 13 of pedestal 12 (Fig. 6) by other the penetrating part 76 formed in pedestal 12 by support unit 72.Cable 68 out can enter (not shown) in motor shell 17 through penetrating part 78 by channel section 77, and in motor shell, cable is connected on drive unit.
In the region in joint 21, holding member 71 overlaps support unit 72 with getting loose and form the housing 79 for the protection of cable 68 together with this support unit.
In a word, form the passage 80 for connecting cable 68 in mode described above, it has by door handle device 19 and the first passage section 81 that formed of its handle beam 24 and second channel section 77 especially.Channel section 77 and 81 at joint 21 place by holding member 71 and support unit 72 ground interlaced with each other transition.In passage 80, cable 68 is reliably protected in order to avoid dirt and clean liquid impact.
Except locking device 54, single disc-type machine 10 has for preventing door handle device 19 around safeties 82(Fig. 7 to Fig. 8 B of pivot axis 22 pivotable).Safeties 82 are incorporated in joint 21, and these safeties comprise the guide body 83 of the plate shape be fastened on support unit 72.Formed in guide body 83 favour horizontal line orientation, for the guide portion 84 of the first insurance institution 85 of safeties 82.First insurance institution 85 is with the form design of the safety plug 86 can passed under the influence of gravity individually along guide portion 84.Safety plug 86 can with the second insurance institution 87 acting in conjunction of safeties 82.Second insurance institution 87 is the spaces 89 taken the shape of the letter U formed on the edge 88 of holding member 71.
By safeties 82 prevent occupy resting state when door handle device 19 and parked with the single disc-type machine 10 of vertical orientated door handle device 19 time (Fig. 5 and Fig. 6), pedestal 12 is overturning on the direction of placed side by mistake.Namely can occur, under this state of single disc-type machine 10, user slips up ground manipulation device 67 and being transferred in the state of getting loose by locking device 54 thus.In the case, insurance institution 85 and 87 occupies safety position because guide portion 84 obliquely downward on the direction of floor orientation, namely rotate clockwise 90 ° of ground and observe Fig. 8 A.Because insurance institution 85 and 87 occupies safety position, so pedestal 12 stops relative to the safeties 82 that are pivoted through of door handle device 19.Even when by mistake get loose locking thus prevent pedestal 12 pivotable and such as overturning on user's pin.
In contrast, when the planar horizontal orientation that pedestal 12 limits, even if when door handle device 19 occupies resting state, insurance institution 85 and 87 also occupies release conditions.In the case, guide portion 84 tilts upward orientation, and safety plug 86 discharges space 89(Fig. 8 B under the influence of gravity).Ensure that thus, the door handle device 19 for being come into operation by single disc-type machine 10 only has and can be pivoted in duty when the approximate horizontal orientation of pedestal after lock release.
