Definitions

  • the present invention relates to a multifunctional terminal for external suction tubes of vacuum-operated electrical domestic appliances.
  • These accessories essentially comprise at least one nozzle having a narrow opening and a brush provided with a hollow central body and with a mouthpiece to be used on fabrics and “quilted” materials.
  • the accessories are inconvenient to use because the user must, on each occasion, find the accessory to be used, remove the one previously used and put it away and fit the one now selected.
  • the present multifunctional terminal for external suction tubes of vacuum-operated electrical domestic appliances comprises a tubular body forming a nozzle-type mouth at a distal end and a cylindrical mouth at the opposite, proximal end capable of being coupled by pressure-fitting to the head of the said external suction tube, at least one pair of parallel guides formed in diametrically opposite positions on the external surface of the said tubular body, at least one cleaning accessory comprising an active end and, opposite to the latter, a tubular base provided with means for twist-and-slide coupling to the said parallel guides for longitudinal sliding therein between the said proximal end and distal end, and vice versa, of the said tubular body and the rotation of the said accessory at the distal end of the said guides for the coaxial fitting of the said base on the said distal end of the said tubular body, and means for retaining the said cleaning accessory in the substantially proximal position of non-use of the said guides.
  • FIG. 1 is an overall lateral view of the multifunctional terminal according to the invention, provided with two accessories shown in the position of non-use;
  • FIG. 2 is a cross section through the multifunctional terminal in the plane marked II-II in FIG. 1;
  • FIG. 3 is a cross section of the multifunctional terminal in a plane marked III-III in FIG. 1;
  • FIG. 4 is a detail of a longitudinal section of the multifunctional terminal in a plane marked IV-IV in FIG. 3;
  • FIG. 5 shows the multifunctional terminal with a first brush-type accessory fitted in the position of use
  • FIG. 6 shows the multifunctional terminal in partial section at the distal end, the movement for fitting the brush-type accessory according to FIG. 5 being shown in broken lines;
  • FIG. 7 again shows the multifunctional terminal in partial section at the distal end, on which is fitted a second mouthpiece-type cleaning accessory for quilted materials and fabrics together with, in broken lines, the movement for the fitting thereof.
  • 1 globally designates a multifunctional terminal for external suction tubes 2 with which vacuum-operated electrical domestic appliances are normally equipped, such as vacuum cleaners and electrical brooms, these not being illustrated because they are known.
  • the terminal 1 essentially comprises a tubular body 3 which is preferably rectilinear and forms a nozzle-type mouth 4 at one, distal end 5 and a cylindrical mouth 6 at the opposite, proximal end 7 , susceptible of allowing the coupling by pressure-fitting of the abovementioned distal end 5 to the head of the external suction tube 2 .
  • the terminal 1 in the preferred form of embodiment, is provided with two cleaning accessories, a brush-type accessory 9 and a mouthpiece-type accessory 10 that can be used on “quilted” materials and fabrics.
  • Each of the accessories 9 and 10 comprises an active end 11 and, opposite thereto, a base 12 which is likewise tubular and provided with means 13 for twist-and-slide coupling to the two pairs of parallel guides 8 ; the means 13 permit the longitudinal sliding of the accessories 9 and 10 along the abovementioned pairs of parallel guides 8 between the said proximal end 7 and distal end 5 and vice versa.
  • one of the accessories 9 and 10 When one of the accessories 9 and 10 reaches the distal end 5 of the pairs of guides 8 , it can rotate in order to be fitted by its base 12 onto the nozzle-type distal end 5 of the tubular body 3 .
  • the two pairs of guides 8 are formed by respective parallel ribs 15 projecting outwards from the perimetral surface of the body 3 , diametrically opposite to one another and joined at their ends by a curved closure section: the said perimetral surface forms, together with the said guides 8 , blind holes.
  • the twist-and-side coupling means 13 of the bases 12 of the cleaning accessories 9 and 10 comprise, for each accessory, a pair of parallel brackets 16 which project from the bases 12 , with no substantial break in continuity, and are susceptible of encompassing the diametrically opposed guides 8 .
  • the brackets 16 exhibit, in plan view, substantially the shape of a scaling triangle with uniform vertices 18 coinciding with the respective ends opposite to the base 12 ; the said vertices 18 and the cylindrical buttons are disposed eccentrically relative to a theoretical perpendicular plan of symmetry of the base 12 , designated “P”.
  • the retention means 14 for retaining each accessory 9 and 10 in the proximal position when they are not in use comprise two pairs of pawls 20 projecting from, solidly fixed to and diametrically opposite to the external surface of the tubular body 3 , in the position of the proximal ends of the guides 8 .
  • the above mentioned means 14 further comprise, correspondingly, hollow seatings 21 for accommodating the pawls 30 , which are made in both the brackets 16 of each accessory 9 and 10 and form entries provided with a flare portion 22 having the function of guiding the fitting and forming, at the point of junction with the hollow seatings 21 , retention teeth 23 over which the abovementioned pawls 20 can hook by resilient latching.
  • the cross section of the tubular body 3 is, with the exception of the section which defines the said proximal end 7 for pressure-fitting to the head of the external suction tube 2 , of helixoidal form with at least two rectilinear and mutually parallel sections opposite and perpendicular to the minor diameter, on which the parallel guides 8 are made.
  • the multifunction cap 1 is as follows: it is fitted in a conventional manner, specifically by pressure-fitting on the end of an external tube 2 provided for an electrical domestic appliance, for example a vacuum cleaner, which is connected to the suction body thereof.
  • an electrical domestic appliance for example a vacuum cleaner
  • the cleaning accessories 9 and 10 although remaining at a distance from the active zone of the nozzle-type mouth 4 , are nevertheless within reach when it is necessary to make use thereof.
  • the user extracts, by exerting light pressure on the accessory to be used, the seatings 21 from the pawls 30 , causing the said accessory to slide along the longitudinal guides 8 until the buttons 17 come into abutment against the end closure sections of the ribs 15 which constitute the said guides 8 ; in that position, the buttons 17 act as a fulcrum for the rotation of the preselected accessory, until the mouth of the tubular base 12 thereof is coaxially aligned with the said nozzle-type mouth 4 .
  • the accessory is again caused to move back along the guides 8 for a short distance until the tubular base 12 engages on the distal end of the multifunction cap 1 .
  • buttons 17 relative to the normal plane of symmetry “P” of the base 12 permits the free rotation of the accessory, before its final fitting, there being no interference between the corners of the nozzle-type mouth 4 and the perimetral edges of the base 12 .
  • the accessory fitted on the distal end 5 is removed by following the opposite procedure: in practice, by pulling the accessory gently outwards, in other words causing the buttons 17 to slide until they again come into abutment against the closure sections of the ribs 15 , the tubular base 12 is first disengaged from the nozzle-type mouth 4 ; the accessory is then rotated outwards and is withdrawn along the guides 8 until the hollowing seatings 21 of the brackets 16 once again engage onto respective pins 20 , locking the accessory previously used in that retracted position.
