Abstract

The mop has an adjustable hollow shaft, inside which operates a piston, actuated from the outside by means of a moveable handle, such that said piston is able to reduce the volume of the pressure chamber created in the lower part of the shaft, which communicates with a pushing cylinder of larger section, with its respective plunger, which is connected to the top or ferrule of the mop head, and that throughout the stroke of the plunger, moves the ferrule with its mop head, releasing the cams, that when hitting the protrusion of the same, against the edge of the ferrule, swing outwards until they engage with the perimetral rim of an ad hoc wringer, pressing the mop head and wringing it. The cylinder of larger section comprises two parts that are assembled together, in order to facilitate the spring return system of the plunger and mass production thereof. The system is intended for any method or means that within the prior art, uses the communication of the pressure chambers, and from the actuating handle of the mop, transmits an exponential force to the top or ferrule of the mop head.

DESCRIPTION

OBJECT OF THE INVENTION

The present invention relates to a mop, of those commonly used for washing floors, which incorporates a cleaning tool or mocho, in solidarity with a bowl or bushing and associated with a height-adjustable mast so that the user can work ad gustum, useful that is complemented by a bucket provided in its mouth with a drainer with perimetral flange, generally frustoconical on which the existing water in the mocha is eliminated, by means of the pushing force exerted by the larger piston section, operated from the mop handle itself that is in solidarity with the lower section piston. The object of the invention is to achieve a mop that allows the operation of the draining of your mop to be carried out, with a minimum effort by the user , BACKGROUND OF THE INVENTION

The systems designed to mitigate the effort of draining are well known, from the devices of a lever in which symmetrical plates deform the mocha, favoring the draining, to elastic drainers that, as the squeeze against the drainer, it , tends to close, imprisoning the mocho and favoring the draining, but still, getting a positive effect, the effort to perform the user is still considerable, in addition, the lever devices presents the additional problem that the user loses the natural position , upright, having to bend or bend down to act on the lever. To alleviate these inconveniences, a mop was devised, whose registration application is P200400997 and was internationalized with PCT / 2005000207, to which we refer. The mop that the invention proposes implies a technological advance with respect to the P200400997, for its economic relevance, for its better industrialization, for its assembly system, for its new bushing, for a new cam opening system and for eliminating cams where appropriate

DESCRIPTION OF THE INVENTION

The mop that the invention proposes incorporates several cylinders of different sections communicated with each other, inside which contains a fluid or air, gas and / or tablets, pistons of different sections that fit their respective cylinders, a sliding handle along a hollow mast topped in the cylinder neck of greater section and where, the cylinder of smaller section is housed, and that, unlike the aforementioned application, the mast can be adjusted in height, either telescopically, or by screwing or other adjustable fixing system either in the neck of the cylinder of greater section or in the mast itself

Another feature of the present invention is that the cylinder of greater section is finished off with a hollow piece to the lower outer wall of said cylinder; said cylindrical piece or head, has axes where the cams are coupled, a windows so that the cams can act and two symmetrical and rectangular grooves through which the symmetrical tabs of the lower outer face of the cylinder of greater section are introduced, until proceeding to the closing the cylinder, rotating it through its horizontal groove, preventing the cylinder from leaving the cylindrical part.

Said cylindrical piece is designed to serve as a guide and stop to the piston of greater section, for the operation of the cams and to place a return spring of the plunger, embedded in the same piston, on whose extremities said spring sits below, where it is attached

The seal or O-ring of said plunger and, at the other end, at the base of the cylindrical part; In this way, we manage to assemble and disassemble the assembly in a very simple way, remove or put more resistant springs or less, avoid the machining process of the cams, drilling on the cylinder in order to couple some pins, or avoid doing some grooves to the plunger to serve as a stop, by another axis,

Another essential feature is that the return system with rubber and / or spring in the mast or in the pressure chamber, it was very difficult to industrialize it and once the mop was mounted, it could not be disassembled, under penalty of spoiling it, in addition to the system of the assembly and minimum load of time and work, it has the advantage of replacing, where appropriate, parts, including cams.

Another novelty presented by the invention is the cams, in the previous application, the cams worked when the piston of greater section, when moving on its cylinder, touched against the cams, opening; With this new system, the piston does not touch the cams, they open because they are geometrically designed so that when the piston with a larger section in solidarity with the bushing of the male comes out, they open when touching with the flange of said bushing; in a resting situation, the cams are vertically on the cylinder wall, and the base or base of the cylindrical part, is coupled to the new bushing and whose essential novelty is to present a flange that when touching with the projection of the cams swing outwards, opening to be anchored in the perimeter flange of the drainer.

Thus, when we slide the handle through the hollow mast, we slide the piston of smaller section through its cylinder, which communicated with the cylinder of greater section, causes a thrust force to the piston of greater section, which in solidarity with the bushing of the mop of the mop , move the bushing with its mocho and, the cams with its projection, and that when they meet the flange of the bushing, they swing out until anchored in the eyelashes or flange of the drainer, in order to avoid, the tendency to rise of the whole of the system by the pressure exerted by the piston of greater section, with its drop and mocho against the drainer

In view of the aforementioned figures, it can be observed that the mop that is recommended, its main novelty, resides in the cylinder assembly of greater section Fig. 3 and 4, where the mast Fig is attached to the neck of the cylinder (8) 1. Adjustable: telescopic or screwed on its lower end to the cylinder neck (8)

In the inner face of the neck of the cylinder (8) communicates with a cylinder of smaller section (9), in turn, encapsulated in the bosom of the mast Fig 1. A handle that slides (2) over the groove of the mast ( 1), in solidarity with the piston of smaller section (3) with its seal (4) adjusted to its cylinder (9)

In Fig. 3, we can observe that the cylinder of greater section in its lower part (7), the outer diameter is reduced, finished off with two diametrically opposed tabs (6), in order to couple the cylindrical part Fig. 4, in said cylinder : Said piece, Fig 4, consists of an upper part (10) to be assembled in the cylinder through a slot (12) in the form of a square and which, diametrically opposed, serve as a guide and support by means of said tabs to the cylinder (6), doing the reverse operation, to disassemble it;

In the lower part of the cylindrical part (H), is the base where the cam shafts (13) are inserted, a base that also serves as a guide and stopper of the piston outlet of greater section Fig. 8 (14) and as support in its case of the return spring encapsulated in said plunger

Said piston of greater section Fig. 8 (14) is attached to the bushing of the plug Fig. 6, through a rod (15), which is introduced into the piston itself, such that, when said piston of greater section of its cylinder, said bushing moves, releasing, in turn, the cams which, with its projection (17), touches with the flange of the bushing Fig (18), said cams (16) being opened to be fixed in the flange of the drainer, in order to prevent the entire system from rising, during the stroke of said piston, you can continue pushing to the bushing and this one, to the moo coupled in its rod Fig 5 (19) or another assembly system, against the drainer, draining it

When the mocha is damaged, it is changed to another, coupling its bushing, to the piston of greater section. Said bushing carries holes for water evacuation.

This is a preferred, non-limiting embodiment of the many variants that can be made, by way of example: a circular crown coupled to the lower part of the bushing would favor the process of draining and collecting the mold, having more contact surface or pressed the mocho with the cap and the crown.

Also and based on the same idea, it admits several pistons and / or valves, in the same way that, the return spring can be replaced by another return system, either in the mast itself, in the sliding handle, in the chamber of understanding or in the drainer itself, for this case, the drainer must be elastic or by coupling a spring, so that when the piston is defeated in its draining phase, the drainer itself gags the cylinder or the spring, when it ceases to compress the Mocho, push the cap and this one to the plunger, returning to its initial position

In order that the cylinder of greater section does not rise and with it the whole system, the cams were devised and that these, can be replaced by a cylindrical crown, and a drainer that narrows as it pushes the plunger, favoring, also drained

Another way of suppressing the cams, would be to put one or several valves, one or several cylinder liners, or that the pressure exerted within the chamber, be reduced to a hollow plunger that houses the fluid and where a greater pressure is exerted or put another inner cylinder that counteracts the rise of the cylinder of greater section, or with the incorporation of a camshaft. The system is designed the same, that for the incomprehensibility of the fluid, as for the comprehensibility of the air or the gas.
