DESCRIPTION OF THE PREFERRED EMBODIMENTS OF THE
INVENTION
With particular reference to the said figures, 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 electrir_al 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.
Along the flanks of the tubular body 3, whilst specifically on the external surface thereof, are made two pairs of guides 8 which are parallel and diametrically opposite one another.
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 accessor_Les 9 and 10 comprises an active end 11 and, opposite thereto, a base 12 which is likewise tubular and p2-ovid.ec~ 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 t:he abovementioned pairs of parallel guides 8 between the said proximal end 7 and distal end 5 and vice versa.
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.
Provided at the distal end 7 of the latter are means 14 for securing both, or alternatively one, of the cleaning accessories 9 and 10 when these are not in use by the user.
The two pairs of guides 8 are formed by respective parallel ribs 15 projecting outwards from the perimetral surface of th~~ 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.
From the internal surfaces of the brackets 16 there project, orthogonally thereto, two respective cylindrical buttons 17 ~~oaxia7_ly facing one another and capable of engagement in the guides 8 or blind holes.
The brackets 1~ exhibit, in plan view, substantially the shape of a scaling triangle with uniform vertices 18 coinciding with the respective ends opposite to the base 1'?; 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 Beatings 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 Beatings 21, retenticn teeth 23 over which the abovementioned pawls 20 can rAook by resilient latching.
In the preferred form of embodiment of the multifunctional terminal 1., the cross section of the tubular body 3 is, with t.hE: exception of the section which defines the sa~.d 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 functioning of the rrmltifunction 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 v~~cuum cleaner, which is connected to the suction body thereof.
20 When the user has to employ the nozzle-type mouth 4 alone, he withdraws the cleaning accessories 9 and 10 towards the proximal end of i~he guides 8, causing the buttons 17 with which they are provided at the ends of the brackets 16 to slide in the said guides until the hollow Beatings 21 made therein engage by latching onto the pawls 20, hooking over the retention teeth 23 with which the abovementi.oned hollow Beatings 21 are provided.
In this configuration, 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.
In this case, 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 aga Lnst 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 i2 thereof is coaxially aligned with the said nozzle-type mouth 4.
Once the above mentioned alignment has been completed, the accessory is again caused to move back along the guides 8 f'or a short distance until the tubular base 12 engages on the distal end of the multifunction cap 1.
The eccentricity of the buttons 17 relative to the normal plane of symmetr~.~ "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 me>uth 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 l0 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 Beatings 21 of the brackets 16 once again engage onto respective pins 20, locking the accessory previously used in that retracted position.
By acting upon the other in the same manner as described, it is rapidly replaced in the fitted position of use.
It has been found in practice that the invention described achieves the proposed objects, in other words makes it possible to replace the accessories rapidly on the terminal 1 and have them constantly within reach.
The invention is capable of numerous modifications and variations, all of whi~~h fall within the scope of protection as defined by the wording of the claims that follow.
Moreover, any detail m~iy be replaced by another technically equivalent detail.
In practice, the mater;als used, and the shapes and dimensions, may be of any type dictated by requirements, without thereb;r departing from the scope of protection of the px-esent invention.
Further features and advantages of the present invention will be more apparent from the detailed description of a preferred, though not exclusive, form of embodiment of a multifunctional terminal for external suction tubes of vacuum-operated electrical domestic appliances illustrated by way of indication, but without implying any limitation, in the attached pages of drawings, in which:
