Definitions

  • the present invention regards a kinetic broom.
  • Such brooms essentially comprise an attractively designed and functional box-like body that permits access to the most awkward corners. Inside the box-like body there is housed a suitably powerful electric motor group arranged to drive an impeller that in turn sucks air from a dirt collection chamber.
  • the dirt collection chamber is also in communication with an end opening facing towards, and designed to slide along, the surfaces that are being cleaned.
  • the prior art electric brooms although providing good general performance, do require a motor group that has to be connected either through a cable to the mains or supplied by a battery pack that can be recharged on the domestic mains supply by using recharge units supplied for that purpose.
  • the main object of the present invention is to solve the above problems by providing a kinetic broom that does not require an electric motor or batteries or cables for connection to the mains supply, that is significantly lighter and easier to handle and whose production costs are competitive.
  • a kinetic broom characterised in that it comprises a self-supporting box-like body having a manoeuvring handle at the top, a suction opening at the bottom and at least one lateral translation wheel at each side thereof, at least one of said wheels is arranged to drive a suction unit in communication with a dirt collection container, the said suction unit and dirt collection container being housed in said self-supporting box-like body.
  • the said suction unit comprises a pair of toothed crown gears which are rigid in rotation with said translation wheels, a transmission shaft mounted for rotation in said box-like body, a first driven gear meshing with a respective crown gear and keyed to said transmission shaft, at least one second driven gear keyed to said transmission shaft, an impeller shaft mounted for rotation in a respective seat, a third gear in cascade engagement with said second gear and keyed to said impeller shaft, and a dirt conveying duct extending between the said suction opening and the said dirt collection container.
  • a kinetic broom is indicated at 1 and comprises a box-like body 2, that is self-supporting and has a manoeuvring handle 3 at the top and a suction opening 4 at the bottom, as well as at least two side translation wheels 5, e.g. mounted for rotation about a shaft 5a.
  • At least one of the said wheels 5 drives a suction group 6, that communicates with a dirt collection drawer 7. Both the suction group 6 and the collection drawer 7 are housed inside the self-supporting box-like body 2.
  • the suction group 6, that is operated by repeated pushing movements of the user, comprises a pair of toothed crown gears 8 each of which is coaxial and rigid with the inside face of a respective wheel 5 and engages with a respective first driven gear 9 that is keyed to an end of a transmission shaft 10 mounted for rotation inside the box-like body 2 and extending parallel to shaft 5a.
  • a transmission shaft 10 mounted for rotation inside the box-like body 2 and extending parallel to shaft 5a.
  • the impeller 14 is mounted for rotation in a respective seat 15 preferably located at the end of a duct 16 through which dirt entering the suction opening 4 is conveyed to the dirt collection drawer 7 (Fig. 1).
  • the rotary shaft 13 comprises two co-axial telescopic sections 13a and 13b of which the first section 13a is supported by a freewheel device and the second section 13b is supported by the self-supporting box-like body 2.
  • the sections 13a and 13b can be operatively connected to each other through a key system known per se, not shown in the drawings, so that they are rigidly coupled in one direction of rotation.
  • a filter element 19 is provided between the seat 15 of the impeller 14 and the suction duct 16.
  • this said seat 15 has an outlet 15a for the discharge of purified air (Fig. 2).
  • the self-supporting box-like body 2 is essentially shaped as a pyramid with rounded edges. Through the base of the pyramid the lower suction opening 4 is formed, whereas at the top of the pyramid a coupling 20 is provided for connection to the manoeuvring handle 3 (Figs. 1 and 3).
  • a foldaway foot extension 21 is suitably pivoted to the shaft 5a at the back of the box-like body 2 and its other end is provided with at least one ground wheel 22.
  • the foot extension 21 can thus be manually moved, after the kinetic broom 1 has been lifted from the ground, between an extended position in which it is extended backwards away from the box-like body 2 so that the ground wheel 22 is in contact with the ground (Fig. 1) and a retracted position in which it is leant against and partly underneath the box-like body 2 by being rotated backwards and downwards about the shaft 5a.
  • the foldaway foot extension 21 also carries a block member 23 located at its end close to the shaft 5a and arranged to engage with and block the gear 11 against rotation when the foot extension21 is in its retracted position (Fig. 1).
  • the box-like body 2 carries, at its rear area, one or more hooks 24 that can snap engage with the foot extension 21.
  • the operation of the above described kinetic broom according to the present invention is as follows: the user places the foot extension 21 in its extended position and then pushes the kinetic broom 1 by acting on the handle 3, thus causing the wheels 5 to translate along the floor (ground).
  • the wheels 5 are thus caused to rotate and while rotating transmit the motion to the kinetic suction motor group 6 and, consequently, also to the impeller 14, through the cascade engagement between crown gears 8 and gears 9, 11, 12, advantageously engaging with one another in pre-established transmission ratios, thereby obtaining a gearing-up in the speed of rotation of the impeller 14.
  • the rotation of the impeller 14 can only occur in one direction because the two sections 13a and 13b forming the shaft 13 can be so engaged as explained above.
  • the flywheel 17, keyed to the same shaft 13, or more precisely to its section 13b supported by the freewheel device 18, enables the impeller to maintain the impeller 14 in rotation by inertia also during the short idle times that may occur during manoeuvring and translation of the kinetic broom 1 along the floor.
  • the foot extension 21 is provided at the back part of the box-like body 2 with the wheel 22 for floor contact.
  • the foot extension 21 When the kinetic broom 1 is going to be put away after use, the foot extension 21 is folded back against and partly underneath the box-like body 2. In this configuration, the locking member 23 comes into contact with the gear 11 to block it against rotation and thus it blocks all moving components of the kinetic broom 1. The latter can then be put away like a conventional bristle broom.
  • suction takes place as a result of the partial vacuum generated by the translation of the kinetic broom 1 along the floor, with no need for an electric motor, battery or other means, but simply by using the power developed by the user's pushing action.
  • All the components in the kinetic broom 1 can be made with easily recyclable materials that reduce the cost of disposal to a minimum should the kinetic broom 1 get irreparably damaged.
