Description
[0001] The present utility model patent is aimed at the domestic
cleaning tools sector. More specifically it is directed at the
tools used with normal vacuum cleaners.
[0002] Currently the vacuum cleaner brushes intended for the
cleaning of domestic floors and carpets make a simple fluctuation
or double or articulated joint system available to adjust the rigid
tube tilt, held up and guided by the operator, to the brush rested
on the floor to be cleaned intaking air, dust and cleaning of the
floors and carpets via specific areas and sections. The said
articulated joints, with a double or single tilt, simply presenting
pipes conjugated and hinged between themselves achieving in final
pipeline formed of two or three continuous elements oscillating
between themselves and so as to offer a modest and approximate
peripheral seal, exclusively assessable by the tolerance of the
connection of two or three pipelines, with tolerance being
generally quite slack even for the kind of plastic materials with
which they are achieved. This manufacturing-related factor produces
a serious loss of air flow and especially from the vacuum produced
by the suction machine intaking with obvious shrinkage or loss of
global yield and this in total disharmony with the current energy
recovery concepts.
[0003] Specifically, the present brush, with an appearance similar
to those already present on the market, uses a sucked air flow
system and technique, via this itself, guiding to a high yield with
a specific flexible pipeline never used or applied as regards
similar tools.
[0004] The present utility model patent achieves a brush for the
cleaning of floors of any type both for ceramic paving tiles and of
marble or parquet in strips of wood or plastic, then, as for all of
these brushes, connected to a handle in metal or plastic tube which
operates from the rigid pipe between the brush itself and the
flexible tube directly connected to the vacuum cleaner or to the
centralised domestic suction system.
[0005] The present brush, besides being equipped with all devices
present on the better brushes present on the market shows, in one
single way, a flexible pipe rigidly connected to a suction tube end
and to the other with a linear split or fissure connection placed
on the wide base of the same brush, flexible pipe, which avoids all
of the three filaments of losses of intaken air via the normal
articulated joints.
[0006] Indeed, the present brush, presents, as has been said, all
of the better devices to optimise the various types of cleaning or
suction for which it shall be used, being equipped with a practical
double jointing system for adjustment of the brush level with a
rigid tube axle or even a handle with support wheels from the
articulated joint itself, being equipped with a lesser metal
suction level shaped with split lateral openings for returning
action and small wheels supporting such a level capable of
eliminating possible sliding on the ground of the level itself,
being supplied with fixed and mobile gaskets to isolate the suction
or splits zone and therefore also equipped with a two position
control lever established to position the aforesaid gaskets
according to the types of surfaces to suction, or, floors or
carpets.
[0007] Therefore the present brush, besides evidencing all of this
equipment, quite recurrent in part or "as a whole" and also on
others present on the market, connects, in accordance with the
solution described herein, the flexible tube connection connected
between the first articulated joint, to the suction tube and the
central slot connection or transversal brush work split. This rigid
section flexible tube, connected to the appropriate fixed ends and
with a tin seal guarantees secure continuity between the dusty air
suction zone and the rigid pipe, also with the so called handle of
the vacuum cleaner, operating without any loss of load owing to
fissures or perimeters, in the articulated joint zone, without a
sure seal, thus offering a suction circuit yield, also greater than
50% with regard to the normal brushes and tubes with articulated
joint in suction. Indeed, with this system there are no substantial
variations in the suction section between the brush resting on the
ground, the connection, flexible sleeve collar and the main suction
tube with reduction of noise and a greater yield with regard to the
other tools similar available for purchase.
[0008] Diagram 1 enclosed shows a view from on high of the brush in
the appropriate assemblage.
[0009] Diagram 2 enclosed is instead the median AA section of
Diagram 1 and shows the flexible pipe between the brush and the
vacuum cleaner tube in accordance with the present Utility
Model.
[0010] Diagram 3 shows a view of the brush without the connection
element between the two articulated joints but shows the flexible
tube.
[0011] Diagram 4 is the BB section of Diagram 3 in which internal
connections and the present details of this brush are shown.
[0012] Diagram 5 essentially relates to the CC section where the
gaskets commutation lever is shown from the flooring position to
that for carpets.
[0013] Diagram 6 shows a view from the bottom of the brush rest
level flat.
[0014] Now moving on to an examination of the preferred solution
for the achievement of the present brush; to the numeric references
indicated in the enclosed drawings, the following meanings as
mentioned and reported hereinafter shall be attributed.
[0015] 100 Brush for vacuum cleaner in its own assemblage made in
plastic materials composed of various functional elements fitted
with a double articulated joint, gasket and front mobile brush in
vertical for use on floors or carpets, two wheel couples, slot or
suction split but especially fitted with a flexible tube for
connection between the suction split and the vacuum cleaner
connection tube, pipe without dispersions or accidental or
concentrated load losses.
[0016] 110 Body or frame carrying the brush itself is the
structural element in plastic material.
[0017] 112 Transversal pipe or slot of suction split with
connection central to the vacuum cleaner suction pipe, is used for
sheet pressing but also pressing of plastic material; glued to it
are a couple of small anti-friction and wear and tear sliding
blocks as on any other brush.
[0018] 114 Indication arrows from the reverse suction or air flow
to the main tube or pipe.
[0019] 116 Connection or pipe linking between 112 and 120 flexible
sleeve collar which is the main subject of the present Patent.
[0020] 118 A pair of wheels on brush support flat avoid ground
friction between surfaces lower than the same and the ground.
[0021] 120 Flexible sleeve collar placed between articulated joint
132 higher pipe on the second fulcrum, and connecting connection
116 of 112, is the most important detail and in accordance with the
present Patent's solution, it is achieved with a flexible tube
fitted with rings or metal spirals to reinforce the extreme
surfaces of the tube itself which, due to internal suction, might
be deformed and close towards the centre with the present sleeve
collar having an air passage section equal to 116 and 132-146 and
also to connection 112, not creating in these transit zones
different between their turbulences thus producing a major yield
and minor losses.
[0022] 122 Clamp, by way of example, of the setting of 120 to
116.
[0023] 124 Front fiber brush, present on the front of 100 as is the
case for almost all for all of the vacuum cleaner brushes available
on the market; can be lifted and lowered to the ground, with a
pedal mechanism schematized in 160.
[0024] 126 Rear seal gasket with functions similar to 124; it can
be raised or lowered together with 124 but can also be fixed.
[0025] 128 Profile less than U fixed on 110 for stiffening and
support of wheels 118.
[0026] 130 Greater fairing applied to 110.
[0027] 132 Rigid upper articulated joint pipe towards the suction
tube; the upper end of 120 is connected to this.
[0028] 134 Intermediate oscillation support between brush body 110
and upper articulated joint 142.
[0029] 136 Lower oscillation axle of support 134 (first
fulcrum).
[0030] 138 Reverse of oscillation with regard to first axle
136.
[0031] 140 Reverse of oscillation with regard to wheel axle
144.
[0032] 142 Upper oscillating articulated joint, around second
centre 144.
[0033] 144 Second fulcrum. Rear wheel axle 154.
[0034] 146 Rigid exit sleeve collar on second articulated joint
142.
[0035] 148 Axial retaining ring for rotation and oscillation of
146.
[0036] 150 Reverse of oscillation of 146.
[0037] 152 Tubular stub pipe of 142, leads to the interior of 148
and 146.
[0038] 154 Wheels, on second articulated joint.
[0039] 160 Pedal for the control of elastic movement levers of 124
and possibly 126.
[0040] 162 Shaft for the movement of the bistable mechanism
activated by 160.
[0041] 164 Pair of anti-adhesion sliding block runners of 112,
flanked by slot 112 in central position and with maximum
suction.
[0042] 166 Arrows indicating lifting-lowering of 124 and 126.
[0043] A brush for vacuum cleaner 100 is shown in the functional
views from on high complete as in Diagram 1 or sectioned according
to a transversal AA median flat as in Diagram 2 in table 1/4
attached.
[0044] These diagrams 1 and 2 show a solution in accordance with
the brush mentioned in the present Patent, so that the
functionality of the flexible pipe 120, connected on one side to
pipe 116 and on the other side to pipe 132 can be understood, and
therefore by rotating articulated joint 142 with respect to axle
144, said pipe 120 will adjust to the subsequent positions assumed
by brush 100 with regard to the inclinations of 146, maintaining
air flow path continuity according to 114 and safely without
dispersions or lateral air returning actions on various articulated
joint joins as instead happens today in all cases. As already
expected, with flexible connection 120 and sleeve collars and
adjacent connections, there are no section variations in the sucked
air path in the brush crossover, unlike what is the case with
brushes currently on the market; the risult is less turbulence,
more silence and above all fewer losses.
[0045] The axes of two fulcrums of articulated joints 144 and 136,
the suction slot in section 112, the front 124 mobile brush and
rear gasket 126, movement supports without sliding by means of
wheels 118 placed on 128 and to the rear, of second articulated
joint, wheel 154 are always shown in these diagrams. Therefore this
brush offers all the operative possibilities of the best vacuum
cleaner brushes but it also ensures a higher yield of 50% compared
with the current models, without there being losses on all joins or
articulated joints, both single and double.
[0046] Subsequent Diagrams 3 and 4 further clarify the preferred
manufacturing method in accordance with this flexible 120
connection solution between the brush and oscillating articulated
joint 142, according to 140, the articulated joint 136 first axle
position, all in good view in the absence of element 134 of the
intermediate articulated joint (Diagram 1). In addition, sleeve
collar 146 being able to rotate according to 150, the total freedom
of movement of (100) is clearly noticeable with regard to the tube
or handle of the vacuum cleaner.
[0047] Diagram 5 adds nothing more about flexible sleeve collar 120
but it shows, particularly in section CC, that movement pedal or
lever 160 of brush 124 according to 166, in some cases even 126,
can follow in vertical movement 124 and these movements produce a
better use or in the suction of floors or carpets.
[0048] Lastly in Diagram 6 a view from the bottom is shown with
slot 112 or slit with a central suction opening which is then
connected to the rear with 120, wheels 118 on profile 128 and
wheels 154 on articulated joint 142.
[0049] To conclude and as has many been times been asserted, this
brush 100 offers all characteristics and services of the best
brushes for carpet or floor vacuum cleaners but it sets itself
apart from these for connection 120, without losses or dispersions,
with an increase in yield without sacrificing any of the
performances provided by analogous tools.
