Description
- The present invention relates to rotating-tool cleaning appliances, and in particular a portable rotating-tool appliance.
- This type of appliance is widely used especially for cleaning not very large surfaces that are difficult to get at with larger appliances.
- Document U.S. Pat. No. 6 058 542 discloses a portable electric cleaning device: the cleaning device comprises a housing, an electric motor, a cleaning member, and batteries. The housing has a handgrip and a frame; the motor is installed in the frame of the housing and has a rotating shaft. The cleaning member comprises a cleaning head that can be changed depending on cleaning requirements, and a connection end connectable to the rotating shaft. The batteries are inserted in the housing and drive the electric motor.
- A device of this type is very handy. However, the rotating tool, whether a brush, a felt pad or something else can only detach the dirt from the surface in question, not remove it: removal can be made possible only if the particles of dirt can be carried away, that is either sucked up or made heavier by the action of a liquid.
- Another problem has to do with the possibility of gripping the appliance efficiently depending on the type of use the user is making of it at any particular time: often the handle is in the way and greatly complicates the use of appliances of this type.
- The object of the present invention is therefore to provide a portable cleaning appliance with a rotating tool capable of removing particles of dirt where used, thereby increasing its efficiency of application and increasing its versatility.
- A further object of the present invention is to provide an appliance with various alternative possible ways of holding it, making its use easier and more practical.
- The subject of the present invention is therefore a portable cleaning appliance comprising a body provided with handgrip means and with an interchangeable rotating cleaning tool, the said body containing the drive means of the said tool and the power supply means of the said drive means; there is formed in the said body a pipe which at one end opens onto the said rotating cleaning tool, with which it is in fluid communication, and at the other end is connectable to means for generating a stream of fluid.
- The present invention also relates to a portable cleaning appliance comprising a body provided with handgrip means and with an interchangeable rotating cleaning tool, the said body containing the drive means of the said tool and the power supply means of the said drive means, in which the said handgrip means comprise a handle hinged to the said body, so that its angle with respect to the body can be varied to suit the conditions of use. Advantageously, the power supply means of the said appliance are located in the said handle.
- Other advantages and features of the present invention will be made clear in the following description of certain embodiments thereof. The description, which is given by way of non-restrictive example, refers to the appended drawings, in which:
-

The shell is attached to the said plate by thescrews 412 inserted through the throughholes 402 in the end wall of the said shell 2, and the screws engage in thesleeves 131 formed integrally with theplate 101. The chamber defined by the shell 2 andplate 101 houses the means by which the motion is transmitted from thepinion 115, keyed to themotor 5shaft 105, to thegear wheel 305, coaxial with which is thespindle 315 which rotates inside theseat 222 formed in theend wall 202 of the shell 2, the threaded free end 325 of which is inserted into theconnection head 502 and fastened to it by thenut 512. Around thespindle 315 in theseat 222 are the sealing means 232. The outer edge of thewall 202 of the shell 2 possesses theaxial flange 302 into which thetool 3 is inserted. The saidtool 3 is coupled to the rotatingconnection head 502 by insertion of thefingers 103, which are of essentially conical form and end intoothlike projections 113, capable of being inserted into the radial cavities 522 of theconnection head 502, to which they gain access via theaxial passages 532. - Formed on one side of the shell 2, and integrally with it, is the
pipe 102, which at one end opens onto theend wall 202 of the shell 2, in fluid communication with thetool 3, and at the other end has amouth 112 for connecting it to means for generating a fluid flow, such as a vacuum cleaner or an appliance capable of producing steam, or indeed an appliance capable of producing a jet of cleaning liquid. At themouth 112 is aplug 10 which closes off thepipe 102 if the appliance is being used on its own. -
FIG. 3 shows schematically the power supply circuit for the drive means of the appliance. Thebatteries 6 are connected to themotor 5 by thecontacts 405. The switch 106 is inserted into one leg of the circuit and is operated by thebutton 116. Also visible in the figure is the gear train, which runs from thecup gear 215 to thegear wheel 305 through thegears 205, which connects thepinion 115 keyed to theshaft 105 of themotor 5 to thespindle 315 which, as shown inFIG. 2 , is connected to thetool 3 by theconnection head 502. -
FIG. 4 illustrates a detail relative to the connection between thehandle 4 and the body 1 of the appliance of the invention. As shown in the figure, the opposite end of the body 1 from that connected to the shell 2 has aspigot 301 whose side walls are held in between the twoarms fork 104 at the end of thehandle 4. The two arms and the spigot are connected together by the threadedpins bushes 425 projecting axially from thecavities 311 in the two side walls of thespigot 301. Thebushes 425 are made from theplates 415 which are connected to thecontacts 405, which in turn are connected to themotor 5. Thecylindrical contact elements 506 are forced into thecavities 311 and their lower portion is in contact with thebushes 425 through the action of thetubes pins plugs cylindrical contact elements 506 that point towards therespective plugs bushes respective contact strips sleeves respective arms fork 104 towards theplugs forks spigot 301 are theseals 321, which protect the electrical connections against the risk of contact with moisture, as do theseals plugs plugs projections 244 and 344, respectively, projecting axially outwards from these; these projections allow the user to loosen or tighten the plugs, that is to say the threaded pins in the bushes, to vary the angle of the handle. -
FIG. 5 illustrates a second embodiment of the appliance of the invention. Identical parts are given the same numbers. The body 1 is provided in this case with aside spigot 401, which has, on the side facing the outer side wall of the body 1, acylindrical cavity 411 with a central axial hole 451 running through into thetube 461 formed as one piece with thespigot 401 itself. Thecavity 411 houses theplug 501 which is connected to the threaded end 611 of thepin 601 by means of thebush 511 forced into theaxial cavity 541, in which it is locked by means of the toothlike projections 521 projecting from its lateral surface. Inserted between theplug 501 and thecavity 411 of thespigot 401 is acompressed spring 531; the pin is locked so that it cannot slide axially out of its seat by theelastic ring 631 engaged in the annular groove 621 formed around thepin 601 itself. - The other end of the pin is connected to the
side spigot 404 projecting from thehandle 4 by insertion of itsruled end portion 671 into theaxial bush 414 formed in the saidspigot 404. This end is also given a threaded axial hollow 641 which connects to the screw 544 inserted into thetube 534 of theplug 504, with anannular groove 514 containing the sealing means 524. The pin also has another annular groove 651 housing sealing means 661. Between thespigot 401 and thespigot 404, sealing and slidingmeans 431 are inserted. - The
spigot 401 is provided, on its wall facing thespigot 404, with anaperture 441 through which theconductors 515 connected at one end to thecontacts 505 of theelectric motor 5 can access thespigot 404, which has acorresponding aperture 434. At the other end, theconductors 515 are connected to thecontact strips 706, 806 which run through the spigot's aperture 444—containing sealing means 454—and are connected to the poles of thebattery 6. On the adjoining faces of the two spigots, there are, besides theapertures spigot 404 and engaging with the cavities 471 formed in the wall of thespigot 401. - The operation of the appliance according to the present invention will be obvious from the following account. When preparing to use the appliance, the user selects the appropriate rotating cleaner, in this case the
brush 3 withbristles 303, and fits it onto theconnection head 502, inserting theends 113 of thefingers 103 into the cavities 522 of theconnection head 502, through theaxial passages 532. When thehandle 4 has been set in the most convenient position, pressure on theboot 206 of the switch 106 will start themotor 5 and set thebrush 3 rotating. - If it is wished to combine the action of the appliance of the invention with a source of fluid flow, as for example a vacuum cleaner, a water tap or an appliance capable of generating steam, a hose connected to such a flow generator will be connected to the
pipe 102 formed on one side of the shell 2 and communicating with thetool 3, by inserting the end of the hose of the said fluid-flow generator on themouth 112 of thepipe 102. In this way the dirt, which the tool proper can only remove, will be sucked away through thetool 3; similarly, be releasing steam the rotating tool will be able to attack and remove much more stubborn traces of dirt. - Naturally, the
pipe 102 can also be used simply to connect the appliance to a pole to allow the appliance to be used on surfaces that are difficult to get out directly, such as ceilings or the like. - The
handle 4 can be adjusted through a wide arc with respect to the body 1 of the appliance, even being able to adopt the configuration illustrated in chain line marked 4′. Its positioning is however very stable: in practice, in order adjust thehandle 4, the user must loosen thepins bushes 425 by using therespective projections 244 and 344 of theplugs handle 4 stable. The efficiency of the electrical connection between thebattery 6 and themotor 5 is ensured by thecontacts forks cylindrical contact elements 506, which in turn are connected to thebushes 425 formed from thestrips 405. - The alternative embodiment illustrated in
FIG. 5 has thehandle 4 and the body 1 connected in quite a different way, to allow the conductors to pass through the connection (formed by the twospigots apertures conductors 515 to pass through, and on the other the toothlike projections 464 engaging in the cavities 471 stabilize the connection as far as the angle which the user desires to give thehandle 4 with respect to the body 1 of the appliance is concerned. Theelastic ring 631 placed around thepin 601 advantageously prevents any possibility of accidental separation of the body from the handle, even if the user completely removes theplug 501. - In both embodiments illustrated, the appliance of the invention is illustrated with sealing means preventing liquids getting into the interior of the shell 2, body 1 and handle 4, or entering the connection between these last two parts. This type of embodiment allows the appliance to be used with a high degree of safety, improving its efficiency during cleaning, which can be carried out safely in the presence of water and cleaning liquids.
- The appliance constructed in this way can therefore be used in a wide range of household cleaning situations, either alone or in combination with means for generating a stream of fluid. In this type of configuration the resulting synergy is considerable, as the combined action of the appliance of the invention with such means offers results which hitherto were obtainable only with very much more complicated machines that are naturally much more expensive.
- From another point of view, the ability to adjust the angle of the handle of the appliance while still having the motor power supply battery inside the handle, offers a high degree of practicality of use without affecting the balance of the appliance.
