• the slot 168 is oriented toward the end edges 164 of the side walls 166.
• first joint member 50 On the first joint member 50 is further from an end wall 174, which points in the direction of the suction nozzle 30, in the opposite direction, ie in the direction of the second joint member 54 out, a support wall 176 protruding, which engages from below into the anti-lock member 162. From the support wall 176 extending parallel to each other two side walls 178, which are spaced by a gap 180 of further side walls 182. Each side wall 166 engages one of the gaps 180 between the side walls 178 and 182.
• a projection 184 obliquely in the direction of the support wall 134 facing out, which is formed corresponding to the slot 168 and can engage in these in the deactivation.
• the anti-lock element 162 is held by the first locking element 106, which abuts against the end edges 164 by the biasing element 128.
• the antilocking element 182 can now be pushed away from the end wall 174 on the supporting wall 176, specifically until a locking tooth 192 projecting from the projection 172 in the direction of the actuating surface 186 engages in a recess 190 provided on the side wall 182. In this position, shown in FIG. 7, the front edges 164 protrude so far that the carrier plate 146 can not be moved further in the direction of the row of teeth 118. The first locking element 106 can thus no longer be brought into engagement with the second locking elements 108.
• the blocking device 102 is permanently deactivated by the anti-lock device 160 as described. There is now a continuous pivoting of the hinge elements 50 and 54 relative to each other about the pivot axis 60 possible, in the context of the predetermined end stop positions, ie in a predetermined angular range.
• the hard surface cleaning device 10 is designed in particular in the form of a window vacuum 194, which allows easy cleaning, in particular vertical hard surfaces, for example of window panes, into a floor-deep area due to the intended joint 46, by changing an orientation of the housing 16 and the suction nozzle 30th relative to each other. If no pivoting between the suction nozzle 30 and the housing 16 is desired, the hinge 46 can be locked or blocked by means of the blocking device 102.
• a joint can also be arranged or formed in the region of a wiper lip receptacle 196 for receiving a rear region of the wiper lip 42 or in the region of a support lip receptacle (not illustrated in the figures). In this case, the joint would then be arranged or formed completely on the suction nozzle 30.
• the exemplary embodiment of a hard surface suction device 12 shown in the figures has the joint 46 either on the suction nozzle 30 or on the hard surface suction device 12, depending on whether the joint unit 48 is coupled to the suction nozzle 30, as shown for example in FIG with the housing 16, in which case the suction nozzle 30 can be uncoupled from the joint unit 48, namely from the first joint element 50. In this case, the joint 46 would then be arranged on the hard surface suction device 12 or coupled to its housing 16.
