[0001] Brooms provided of tanks along their handle and with small boards on the foot place
are well known in the market; all this is properly shaped. The outflow regulation
of the products, such as (liquids, waxes or others) inside the tank to be poured out
and spread on the floor which is going to be treated, is carried out in different
ways according to the different connections from the tank downwards.
[0002] As a matter of fact, a split opening tap placed between the tank's lower end and
the lower end of the connection small pipe going down towards the floor can be chosen..
Other accepted solutions are those regarding the regulation of the pressing of the
small and flexible pipe going down from the tank on an intermediary step. The total
closing or the total or partial opening of the outflow of the product going down from
the tank can be carried out depending on the small pipe's pressing.
[0003] A further solution accepted is that regarding the intervention by means of a stopping
cap (or a pin) placed at the outflow small pipe's lower or higher end.
[0004] In the numerous cases of the brooms with the tank for the pouring out or spreading
of products for the floors treatment, the control system for the regulation of the
products outflow from the tank towards the floor is placed at the handle's top. The
control system usually consists of a knob which is lifted up, lowered, turned or tilted
etc..
[0005] The moving of the knob by means of the operator is transmitted to a tie rod or a
strut placed inside the handle. Both the tie rod and the strut contrast the action
of a spring which, being at rest, drives the closing devices the broom is equipped
with.
[0006] The aforesaid devices can be some nibs keeping the small flexible pipe pressed in
an intermediary area between the higher or the lower end; on the other side, these
devices can be constituted of stopping pins or caps inserted or pushed in correspondence
of the higher or lower end of the pipe leading off the tank.
[0007] The placing of the outflow regulation controlling system of the products inside the
tank in correspondence to the top of the brooms' handle presents serious practical
and functional problems.
[0008] When using the broom, clasps the operator both his or her hands on the handle and
for the regulation he or she must stop during the moving so as to operate on the knob
placed on the handle's top.
[0009] If the knob is placed in its block position the total overflow opening is carried
out without the possibility to choke the quantity of flow desired.
[0010] The effort the operator has to carry out on the knob (here it must be taken into
account that the operator consists for the most part of a female staff) is rather
significant since she or he has to contrast a spring whose pre-charge has to be sufficient
to assure the overflow closing both during its activity and to avoid possible spilling
caused by bumps during the brooms placing or taking away from their storerooms.
[0011] In the end, it is not possible to provide the broom of telescoped handles since the
connection from the controlling knob till the point where the regulation devices are
placed (the closing and the opening are included) consists of rods or of struts involving
the whole size of the handle.
[0012] The cability to be able to lengthen the handle enables to reach certain areas which
are going to be treated by means of the broom's lower end; these areas would otherwise
be unapproachable.
[0013] The controlling system of the present patent solves all the problems described above.
[0014] The invention is about a hand lever placed on the handle's intermediary area in correspondence
to the natural position of one of the operator's hand.
[0015] The aforesaid hand lever is like the brakes' lever on the bicycles' handlebar.
[0016] The advantages obtained by means of the present patent's controlling system are listed
as follows.
[0017] By means of a moderate effort, the operator succeeds in contrasting the action of
hardly pre-charged springs, which, being at rest, assure the safe stopping of the
products outflow coming from the tank.
[0018] For the regulation of the products overflow from the tank, the operator does not
need to stop during the moving of the broom.
[0019] Having one of his or her hands always placed on the hand lever the operator determines
the overflow of the products inside the tank going down towards the floor according
to the need.
[0020] By placing the controlling system along the handle's lower fixed step of this patent,
it is possible to provide this broom of a telescopically extension handle.
[0021] When one has to carry out continuous and abundant products pouring out for the floor
treatment or when the control system's hand lever is no longer easily reachable because
of the extension of the telescoped handle, it is possible to place the hand lever
in advance in the block position. Indeed, inside the structure, enclosing the handle,
where the hand lever is hinged, there is a device the operator can insert in order
to block the hand lever in the pressed position.
[0022] Having kept in consideration the peculiar carrying out of this patent's controlling
system whose driving is carried out by means of a hand lever with very uneven arms,
so that significant forces on the opposed arms can be transmitted by means of moderate
pressing of the operator's hand on the lever hand. This hand lever can be linked at
the end of the aforesaid smaller arm provided with kinematic mechanisms (for example
with sheathing and flexible inner wire) which are able to transmit movements to some
elements placed in the distance both inside and in combination with the small board
of the broom placed on the floor level (for example scraping metal sheets, etc.)
[0023] Other advantages come out from the description of a preferred carrying out it is
being described.

Detailed description of the drawings
[0025] With reference to the pictures from 1 to 7.
[0026] It is shown a market broom provided with a handle 2, at whose lower end a small board
1 is placed on the floor to be treated by means of the products inside the reservoir
3, provided at the top of a cover 13, which is coaxial and in an intermediate position
as regard the handle 2.
[0027] A small flexible tube 4 is connected to the lower part of the reservoir 3 and then
it goes down towards the floor after having passed through the lower structure of
the handle 2 within which there is the closing kinematic mechanism of the small flexible
tube 4.
[0028] The closing of the small flexible tube 4 is carried out by driving a control knob
5 placed at the top of the handle 14 applied on the higher end of the handle 2; such
knob 5 when it is pressed, it pushes downward the rod 9, which is inside the handle
2, in this way it contrasts the action of a spring 10 acting on a small piston (connected
to the final end of the rod 9) which supports in turn the closing nib 11 of the small
flexible tube 4, which is integral with the end of the rod 9 opposed to the one on
which the knob 5 acts.
[0029] By means of this action on the knob 5 the flattening action of the small flexible
tube 4 exerted by the nib 11 is reduced or eliminated.
[0030] Inserted on the higher end of the handle 2, there is a button 6 with an external
head; within such button 6 the tubular element 29 slides; it is internally coaxial
and integral with the knob 5 through which the knob 5 is connected and acts on the
higher end of the manoeuvre rod 9.
[0031] On such tubular element 29 there is a hollow 27, within which it is engaged the small
key 8 of the button 6; the longitudinal sliding of the small key 8 along the hollow
7 guarantees that the movement of the rod is longitudinal according to the axle of
the rod 9; the final higher part of the hollow 7 ends with an enlargement 30 within
which, upon rotation of the knob 5, can get in the small key 8 to keep the knob 5
in the lowered reached position.
With reference to pictures from 8 to 21.
[0032] It is shown a market broom provided with a handle 2, at whose lower end a small board
1 is placed on the floor to be treated by means of the products inside the reservoir
3, provided at the top of a cover 13, which is coaxial and in an intermediate position
as regard the handle 2.
[0033] A small flexible tube 4 is connected to the lower part of the reservoir 3 and then
it goes down towards the floor after having passed through in the lower part of the
handle 2, an element within which there is the closing kinematic mechanism of the
small flexible tube 4.
[0034] The closing of the small flexible tube 4 is carried out by driving the driving device
which is the subject of this patent.
[0035] The driving device consists of a tubular part 15 coaxial to the handle 2 which is
joint and supports the structure 23 of the adjusting control.
[0036] Such structure presents in its lower part an hinge pivot 24 on which the handle lever
16 is hinged in its own seat 18.
[0037] Such handle 16 consists of two 2 arms having an orthogonal placing between them.
[0038] On the external surface of the greater arm 16 a possible operator's hand goes to
act with the strength directed towards the handle 2, while the aforesaid operator
goes on to keep the hold on the aforesaid handle 2.
[0039] The second lever arm in correspondence to its end 26 acts on the clamp 20 fixed on
the driving rod 9 of the closing kinematic mechanisms of the small flexible tube 4.
[0040] Such second lever arm acts on the rod 9, placed inside the handle, with a direction
which is coincident with the axle of the rod 9.
[0041] Such second arm, extending itself from the hinge point 18 to its driving end in correspondence
to the rod 9, passes through the window 19 on the tubular part 15 of the support 23
and the window 28, practised on the handle 2 in contiguity to the window 19
[0042] On the end opposed to that one of the hinge 18 of the lever hand 16 there is a rim
25.
[0043] On this rim 25, in order to keep the lever hand 16 blocked in closing position you
make the retention device act assembled with the possibility of a limited sliding
in the higher part of the structure 23.
[0044] The retention device for the locking of the lever hand 16, you form a hollow button
17, which is integral with the stem 21 provided at the lower free end of an enlarged
head 27 having the function of a head.
[0045] In order to keep the retention device lifted up in the rest position, not restraining
the rim 25 of the hand lever 16, before the assembly of the hollow button 17 on the
narrow end of the stem 21 (already assembled in the structure 23), it is inserted
in the annular cavity between the hollow button 17 and the stem 21 an helical return
spring (not drawn in the various pictures)
[0046] It has to be reminded that the regulation controlling system for the going out of
cleaning or floors treatment products which is applied on an intermediary step of
the brooms' own handle has been previously considered in the description only by way
of example. The patent's controlling system can be applied on any kind of broom provided
of a tank (or case) made in any way or provided of devices working for the opening,
closing or the regulation on the pipe used for the outflow of the products inside
the aforesaid tank.
[0047] One does not get off this patent for every even ameliorative carrying out that any
expert in his or her field could carry out if he or she makes use of this patent's
teachings.
