Description

BRIEF DESCRIPTION OF DRAWINGS

(1) Further features and advantages of the invention will result clearer with the description that follows of some of its embodiments, made to illustrate but not to limit, with reference to the annexed drawings, wherein:

(2) Figures from 1 to 2B show some possible constructive solutions of cap-broomstick coupling in accordance with the background art;

(3) FIG. 3 shows in section a cap inserted on the broomstick of the broom in accordance with the present invention in a first embodiment;

(4) FIGS. 4, 5 and 5A show possible variants.

DESCRIPTION OF SOME PREFERRED EMBODIMENTS

(5) FIG. 3 shows a first embodiment of the invention. In particular, the figure shows, with number 1, the assembly of the broomstick 2 that is connected to the bristled part 3. (the broom in this example, but any other cleaning tool could be applied). With number 10 the cap 10 is indicated, which is connected in a rotatable manner to the broomstick 2. The cap always foresees an inferior part similar to a sleeve and that forms a channel for the coupling to the broomstick and a superior part provided with hanging means 13 to hang the assembly (1, 10) to the wall (for example in the shape of an eyelet or a hook 13). In accordance with the invention the cap, applied to the end of the broomstick, is now realized in a single piece on which the eyelet or the hook 13 is obtained for the hanging to the wall.

(6) In accordance with the invention, as shown in the enlargement A-A of FIG. 4, the broomstick presents in proximity of its end, opposite to that of application of the bristled part, a notching 5 that runs circularly around the circumference of the broomstick. The circular notching engages inside the cap 10 of FIG. 3, with a circular protuberance 15 obtained inside the channel.

(7) The cap 10 is in a single body that foresees the eyelet 13 and can be realized, for example, of plastic by molding.

(8) It is clear that the realization of the cap 10 in a single piece simplifies significantly the production process because it is now necessary a single mold, unlike in the system of the background art, as previously described.

(9) That being said, going back to FIG. 3, inside the cap 10 are highlighted one or more protuberances 15 which can have the form of a single circular protuberance, that is that runs along the entire circumference of the sleeve, or at sections of variable number. The sleeve is internally hollow to be applied on the broomstick. Such a protuberance 15 is suitable for engaging with the relative notching 5 of FIG. 4 when the broomstick 2 is precisely assembled to the cap 10.

(10) By selecting a diameter of broomstick and cap so that one (the end of the broomstick) is inserted inside the other one (the channel formed by the sleeve) with a certain clearance, a rotatable coupling is obtained. In particular, the protuberance/s 15 is/are inserted in the notchings 5 and the coupling obtained is rotatable. The notching 5 therefore forms a sliding track for the protuberance 15. In particular, the cap 10 can freely rotate with respect to the broomstick and vice-versa, having impeded the translation and therefore the withdrawal of the cap with respect to the broomstick being impeded.

(11) This solution is advantageous since the coupling is very simple and, above all, is long-lasting because, unlike the above described background art described, the cap is prevented from withdrawing from the broomstick thanks precisely to this coupling that uses the protuberance that is inserted into the relative circular seat 5 obtained around the external diameter of the broomstick, and not by being inserted by interference, but with minimum clearance, and does not feel the effects of thermal differences and stresses exerted by the user.

(12) It is clear that if the seat or notching 5 is circular (that is continuous along the entire external diameter of the broomstick) the broomstick will be able to rotate freely with respect to the cap of 360. Nothing would impede to realize a notching of an inferior length, allowing more limited rotations, for example of just 180.

(13) FIG. 5 shows an obvious variant that, in fact, is an inverted solution with respect to the preceding one.

(14) The figure shows how in this variant a notching 50 can be obtained inside the sleeve of the cap and the relative complementary teeth 150 can be on the end of the broomstick.

(15) In a third variant of the invention, not described in figure, a first part of the cap could be foreseen (the inferior part) that is inserted into a channel formed in the broomstick. In this case, therefore, the broomstick has to form a holding channel inside of which the inferior end of the cap is inserted, which can therefore be full. The coupling takes place also in this case with clearance and the ordinary first and second connection means are foreseen for allowing the free relative rotation between the parts, but impeding that the cap withdraws from the broomstick.

(16) It is clear that the present invention is applicable not just to brooms but to all the category of cleaning devices that foresee also wiping rags for washing the floors, trowels, industrial brushes and to all types of wooden, metal in a single piece, telescopic or multi-piece broomsticks, both varnished or laminated, and of any diameter that foresees a rotatable cap.

(17) It is also clear that the external form of the cap can be of any type (cylindrical, bulge formed with lines or smooth, with close eyelet or with open hook), with writings in relief or embedded, with writings engraved up to the internal part, see FIG. 5A of the cap, etc.
