  • Figure 5 is the corresponding lateral schematic view of Figure 4.
  • Figure 6 is also a lateral view of the connector according to the invention to which a brush accessory for padded items is attached;
  • Figure 7 is a schematic view from above of an attachment connector of work accessories for vacuum domestic appliances, provided with a narrow brush accessory;
  • Figure 8 is the corresponding lateral schematic view of the connector and of the accessory of figure 7;
  • Figure 9 is a side view of the connector according to the invention, to which a narrow brush accessory ' is attached.
  • 1 indicates an attachment connector of the work accessories 2, 3, 4 to the suction pipes 5 of vacuum domestic appliances.
  • the connector 1 essentially comprises a box body 6 that defines a projecting standardised fitting 7 couplable to, or fittable on, an end of a conventional suction pipe 5 and an attachment jaw 8 of one of the work accessories, which is in a zone of the box body 6 substantially opposite the standardised fitting 7.
  • a chamber 9 is defined for connection between the standardised fitting 7 and the attachment jaw 8 and for housing a rotating body 10, rotatably free, which is actuatable by rotational motion with the same suction action of vacuum domestic appliances.
  • Each of the work accessories 2, 3, 4 comprises a body 12 along which a through cavity 13 passes longitudinally that respectively ' defines a first suction and contact opening 14 with surfaces to treat and a second opening 15 for connecting with the attachment jaw 8.
  • Each work accessory 2, 3, 4 is also provided with dynamic brushing means 16 that is actuatable by rotational movement and is rotationally mounted at the first suction and contact opening 14 with surfaces to be treated, with leaded means 17, which is engageable with the first transmission means 11, which is located at the second connection opening 15, and with second transmission means 18 of the rotational movement that is interposed between the leaded means 17 and the dynamic brushing means 16.
  • the attachment jaw 8 is provided with means 19 for the sealed hooking or unhooking of converging ends of the accessories 2, 3, 4 each of which is advantageously provided, at the respective converging end turned towards the jaw 8 in hooked configuration, with sealed coupling means 20 with the hooking or unhooking means 19.
  • the rotating body 10 comprises a shaft 21 that is traversely supported rotationally inside the chamber 9 inside the box body 6 of a fan 22 splined on the shaft 21 and rotationally integral therewith; support means 23 of the shaft 21 is also provided that comprises two heads 24 and 25 suitable for receiving the ends of the shaft 21 and which protrude, aligned on one another in a direction that is centripetal from the chamber 9; between the heads 24 and 25 and the ends of the shaft 21 antifriction means 26 is interposed, for example spherical bearings.
  • the first drive means 11 comprises an extension segment 121 of the shaft 21, a reel 27 that is splined on the extension 121, coaxially to the fan 22 and a pulley 28 that is freely supported rotationally in one of the heads, namely 25, and is turned towards the attachment jaw 8, in such a way as to emerge from the latter and engage in the reel 27.
  • the dynamic brushing means 16 comprises a substantially cylindrical element 29 that is rotationally supported transversely free in the body 12 and is peripherally provided with cleaning and/or polishing means, such as for example bristles 30, and with at least one toothed organ 31 for connection to the second transmission means 18.
  • the leaded means 17 comprises a second shaft 32, that is transversely supported inside the body 12 of the accessories 2, 3, 4, and two second heads 33 and 34 supporting the ends of the second shaft 32, which project centripetally opposite and coaxially.
  • the leaded means 17 furthermore comprises a toothed gear 35 that is splined on the second shaft 32 and which is engageable with the pulley 28 and a second reel 36 that is splined on the second shaft 32 coaxially with the toothed gear 35.
  • the second drive means 18 comprises belt or chain means 37 closed in a loop on the second reel 36 and the toothed connecting organ 31.
  • the sealed hooking and unhooking means 19 with which the accessories 2, 3, 4 are provided comprises at least one fulcrum pin 38 that projects outside the body 6 and elastically active gripper means 39 that is engageable with the sealed coupling means 20, which essentially comprises a lip 40 obtained projecting at the perimeter outside the second opening 15 connecting with the attachment jaw 8 and with at least one hooked foot 41 suitable for engaging in the fulcrum pin 38.
  • the operation of the connector 1 and of the corresponding work accessories is as follows: the fan 22, splined on the first shaft 21 and inside the chamber 9, is made to rotate by the current of air sucked in by the motor of a vacuum domestic appliance, for example a vacuum cleaner.
  • the rotation of the fan 22 also actuates means 18 of transmission of rotating motion, which in turn rotates the dynamic brushing means 16 with which the work accessories 2, 3, 4 are advantageously provided and which takes on different shapes depending on the type of accessory and its intended use.
  • the rotational motion to which the fan 22 is subjected by the suction action is transmitted through the reel 27, to the pulley 28 and from the latter to the toothed gear 35 splined on the second shaft 32 on which the second reel 36 is also splined.
  • belt or chain means 37 is closed as a loop that definitively takes the rotational movement of the fan 22 to the dynamic brushing means 16, which in this case comprises for example a pair of round brushes splined on the ends of the substantially cylindrical element 29 advantageously protruding bilaterally from the body 12 near the first suction opening 14.
  • the dynamic brushing means 16 comprises for example a pair of round brushes splined on the ends of the substantially cylindrical element 29 advantageously protruding bilaterally from the body 12 near the first suction opening 14.
  • the connector 1 Operation of the connector 1 is substantially identical even for the accessories 3 and 4 that have different conformations because they are intended for different uses but which all combine the suction action with cleaning action by brushing by making the bristles 30 rotate; in detail, the brush accessory 3 (figures 4, 5, 6) is specially used to treat padded items in general whereas the narrow brush accessory 4 is used for surfaces with a small extent and which are difficult to access. It should be mentioned that all the work accessories 2, 3, 4 are hooked to the attachment connector 1 by inserting the hooked foot 41, with which all are advantageously provided, into the fulcrum pin 38 and tightening the perimeter lip 40 with the gripper means 39.
  • attachment jaw 8 of the box body 6 and the second connection opening 15 face each other and with the respective perimeter edges pressed tight against one another.
  • the materials used and the shapes and dimensions can be of any type, according to needs, without thereby falling outside the protective scope of the present invention.
