Description
- The present disclosure relates to a floor scrubbing machine.
- Conventional floor scrubbing machines for industrial use have a box-like base structure, provided with wheels, which accommodates at least one nozzle for dispensing a washing liquid and at least one brush that removes dirt from the floor.
- To the rear of the brush, with respect to the travel direction of the machine, there is a squeegee, which allows to recover the washing liquid together with the dirt removed by the brush, so that they can be collected by an intake that dries the floor.
- Usually, a handle is connected to the box-like base structure and is provided in an upper region with a grip that allows to move the machine on the floor.
- In current machines, the handle is connected to the box-like base structure by means of a hinge that defines a single rotation axis arranged substantially horizontally and substantially transversely to the travel direction of the machine, in order to allow to adjust the position of the grip depending on the height of the user.
- These machines are rather awkward to maneuver, especially in areas of limited space, such as in the case of households.
- Moreover, current machines have the disadvantage of being able to work correctly only in one travel direction, which corresponds to the one in which the nozzles for dispensing the washing liquid and the brush precede the squeegee, because by moving the machine in the opposite direction, i.e., backward, the squeegee cannot retain the washing liquid emitted by the dispensing nozzles and the dirt removed by the brush, leaving therefore the floor wet and dirty.
- This prevents a valid use of these machines to clean floors under tables or furniture in general and, more usually, wherever it is necessary to move the machine back and forth in order to clean the floor.
- The aim of the present disclosure is to provide a floor scrubbing machine that is extremely easy to maneuver and allows to clean the floors even when it is necessary to move the machine both forward and backward.
- Within this aim, an object of the disclosure is to provide a floor scrubbing machine that is structurally very simple and is low cost.
- Another object of the present disclosure is to provide a floor scrubbing machine that can be used validly both in a professional environment and in a household environment.
- This aim and these and other objects that will become better apparent hereinafter are achieved by the floor scrubbing machine, according to the disclosure.
- Further characteristics and advantages will become better apparent from the description of a preferred but not exclusive embodiment of the floor scrubbing machine according to the disclosure, illustrated by way of non-limiting example in the accompanying drawings, wherein:
-
FIG. 1 is a perspective view of the machine according to the disclosure; -
FIG. 2 is an exploded perspective view of a part of the machine according to the disclosure; -
FIG. 3 is an enlarged-scale perspective view of a detail of the machine according to the disclosure; -
FIG. 4 is a perspective view, with parts removed for convenience, of a joint associated with a handle of the machine according the disclosure in the condition in which the handle is locked in a substantially vertical position; -
FIG. 5 is a view of the joint ofFIG. 4 in the condition in which the handle is folded back on the box-like base structure of the machine according to the disclosure in a substantially horizontal position; -
FIGS. 6 , 7 and 8 are perspective views of the machine according to the disclosure in a sequence of steps of its use. - With reference to the figures, the floor scrubbing machine according to the disclosure, generally designated by the

universal joint 12 also comprises second removable locking means that allow, instead, to lock thehandle 9 with respect to the box-like base structure 2, about at least thefirst rotation axis 12 a, at least in a second position, in which the handle is arranged so that its axis is substantially parallel to the floor, so as to be folded onto the box-like base structure 2, so as to reduce the vertical space occupation of the machine when not in use. - In greater detail, the
universal joint 12 comprises at least onefirst body 14, which is coupled rotatably, about thefirst rotation axis 12 a, to the box-like base structure 2. - A
second body 15, which is associated with thehandle 9, is in turn coupled rotatably about thesecond rotation axis 12 b to thefirst body 14. - In particular, the
second body 15 has, conveniently, atubular portion 15 a for accommodating the lower end of thehandle 9, while thefirst body 14 has a pair of mutuallyopposite eyelets 14 a, to which thesecond body 15 is articulated about thesecond rotation axis 12 b. - According to the illustrated example, the first locking means of the
universal joint 12 comprise atab 16 that protrudes from thesecond body 15 substantially parallel to the axis of thehandle 9, passing thought thefirst body 14. - The
tab 16 can be engaged removably within alocking seat 16 a, which is defined on the box-like base structure 2, when thehandle 9 is arranged so that its axis is substantially perpendicular to the floor. - More particularly, the
locking seat 16 is defined on anabutment body 17 that is mounted on the box-like base structure 2 by way of the interposition of elastic pusher means, constituted for example by a pair ofsprings 18. - With reference to the embodiment shown in the figures, the
abutment body 17 is constituted by anelongated plate 19 that has, in an intermediate position, on its upward facing surface, a rounded recess that provides thelocking seat 16 a. - As shown, the
elongated plate 19 is conveniently mounted within aframe 20 that is fixed on the inner side of the box-like base structure 2, around awindow 21 opened on the upper face of the box-like base structure 2. - Conveniently, the
elongated plate 19 is surmounted by a coveringbody 22 having a throughhole 23 at thelocking seat 16. - Advantageously, the
first body 15 of theuniversal joint 12 has a pair ofrotation pivots 24, which protrude laterally on mutually opposite sides with respect to thehandle 9, which define thefirst rotation axis 12 a and engage rotatablyrespective rotation seats 25 defined in the box-like base structure 2. - In particular, the
rotation seats 25 are, conveniently, provided partially by means of a pair oflateral supports 26, which protrude upwardly from the box-like base structure 2, at opposite edges of thewindow 21, and are partially defined by a pair ofsupports 27, which couple to the lateral supports 26 and protrude upwardly from the opposite ends of the coveringbody 22, ending with arespective sag 27 a, which cooperates to provide acorresponding rotation seat 25 with the correspondinglateral support 26. - Advantageously, the second locking means of the
universal joint 12 comprise, at at least one of therotation pivots 24, arespective retention tooth 28, which is provided for example on a shaped body that is laterally adjacent to therelative rotation pivot 24, along therotation axis 12 a, and is adapted to engage removably acorresponding retention seat 29, which has a corresponding shape and is defined on theabutment body 17, when thehandle 9 is arranged so that its axis is substantially parallel to the floor. - In particular, there is conveniently a
retention tooth 28 at eachrotation pivot 24 and theseats 29 for retaining theretention teeth 28 are defined at the free end of respective raisedportions 30, which protrude upwardly from the longitudinal ends of theelongated plate 19 that provides theabutment body 17 and each of which is laterally adjacent to arespective support 27 defined by the coveringbody 22. - It should be noted that the
