Definitions
- the present invention relates to the technical field of the construction, more specifically in the area of the finishes thereof, since it provides a mechanism for supplying paint to a brush or roller.
- Patent US 1829850 explains new and useful improvements in brushes and particularly with a fountain brush that is provided spontaneously of the liquid or of the solution of a container joined in a continuous stream.
- the main problem of these systems under pressure is that as the consistency of the paint is uneven, if there is a phlegm stuck, when the valve that regulates its output is opened, only a small trickle will be injected, but then when the phlegm or lump it is released, a borbollón will be thrown away; in addition to this, the pressure in the paint can is not constant, nor the difference in height between the can and the brush, which constantly rises and falls.
- the painter does not have a control of the paint that injects and will cause excessive draining, so that these systems work satisfactorily for rollers, which in their interior, can contain a significant amount of the paint in excess, and by letting go slowly, they also work with a sprinkler, which directly spreads the paint on the surface to be painted. But they do not work properly for a brush, because the amount of excess paint that it can absorb is minimal. Any excess that exceeds the capacity of capillarity in the bristles will spill.
- Patent US 2932043 details a device for applying paint that has four functional members, one of them being a spring in the outlet valve, where there is force and the pressure is not critical, but if it reinforces the seal by the upper part that is where the air can be filtered and eliminates the spring in the inlet valve, where the important thing is the strength and not the sealing. Although it is a single spring, it is very susceptible to corrosion. It also explains how their "check" valves can be disassembled and washed, but not in their internal parts so that they do not leave leaks and remain firm, that is, the internal part of these valves is inaccessible to washing. In addition, the spring being thin and steel, is very susceptible to corrosion or can not be replaced.
- suction pump lacks strength, although the inventor does not use a spring in the intake valve, and that it adds suction effort and although he explains that his pump will be strong enough, to return to its form original and suck a thick liquid, this cylindrical design, is simply unsuitable to exert a considerable suction force.
- Patent application PCT / MX2006 / 000076 describes a paint supply system for brush or roller, where the drawbacks are: a difficult cleaning since a lot of paint gets stuck in the ducts and in the spring valves, the assembly of the upper and lower parts is delayed by the shape of its manufacture and the model is very rustic, in addition to the shape in which the paint is distributed to the bristles is very slow and takes a while to distribute well over the bristles of the brush.

- Figure 32 is an explosive section of an adopted piece for securing the lower end of the hose to a water intake.
- the mechanism for efficiently supplying the paint to a roller or brush is constituted by:
- a suction / ejection pump to supply the paint to a roller or brush which in turn comprises an open cavity 1, preferably circular, similar to that of the patent application PCT / MX2006 / 000076, but with the difference that this cavity 1 is deeper or deeper ( Figures 3 and 5) to provide more paint.
- the cavity 1 is closed hermetically with a circular cover formed by an elastic membrane 2, whose perimeter 3 is thickened and reinforced, in such a way that it forms a kind of ring, which is introduced under pressure in a channel 4 located in the external upper part and surrounding said cavity 1.
- Ia t ⁇ p ⁇ has a tongue 2 'on its perimeter, which serves to pull and extract the lid of the channel 4 that surrounds the cavity 1; therefore, said channel 4 has a small recess 4 'where tongue 2' is received.
- the cavity 1 has two extensions passed and externally threaded 5 and 5 ', diametrically opposite each other, which serve as connectors to hold accessories, such as a brush, the handle of a roller or hoses, among others.
- the lower extension 5 has a narrow duct 7 that connects with the hollow of the cavity 1 and at its other end joins a wide duct 6 where a first valve 8 with nozzle in the form of "duck's beak” is introduced, made of an elastic material and resistant to deformation.
- This first valve 8 is mounted on the thick end 9 of a male connector passed in the shape of an arrow, therefore, in the wide duct 6 is lodged said first valve 8 and the wide end 9 of the male connector, leaving its nozzle oriented towards the narrow conduit 7, to allow the introduction of paint into the cavity of the pump.
- the other end 11 of the male connector is thinner and ends in arrowhead, which is introduced into the thin conduit 13 of a removable piece 12 until the stop 10 of the male connector reaches the internal step of the detachable piece 12; therefore it is evident that said demountable piece 12 is open cylindrical, whose interior denotes two sections, the thin duct 13 already mentioned and an upper duct that is wide and internally threaded 14, to receive the external thread of the lower extension 5 and remain in this way assembled both pieces.
- the upper section 5 'of the paint supply system is similar in construction to the lower section 5, with the difference that instead of having a wide conduit 6, it ends in a point 15 of The thickness of the wide end 9 of the male connector, so that a second valve 8 'with a nozzle in the form of a "duckbill" is mounted on it, the valve 8' is already inserted into the cavity 16 of a female connector in the form of an arrow, whose tip 18 is inserted into a second removable cylindrical piece 12, until its stop 17 makes contact with the internal step of said removable piece.
- the second valve 8 ' is oriented towards the tip in the shape of an arrow 18, in such a way as to allow the output of the paint towards the painting device.
- the mechanism must be well hermetically sealed, so that there is a vacuum and what is circulating inside is only the paint.
- This mechanism can be adapted to paint devices that self-supply this liquid, more specifically to rollers or brushes. For that reason I proceed to detail some examples of application of this mechanism.
- a handle to hold the roller ( Figures 6, 7 and 8); wherein said handle is constituted by a cylindrical body 24, preferably; whose interior is passed through a conduit 77 to allow the passage of the paint, its upper end ends in an externally threaded reduction 26 to be screwed with an internally screw cap 27, and its lower end ends in an arrowhead 25 to be connected a hose 29 which in turn will be connected to the paint supply mechanism already described.
- the threaded cap 27 has a central bore 23, where the open end of a tube 20 that supports the tufted roller 21 is introduced, so that the paint continues its way through said tube 20 until it exits through a series of small perforations 22 that are located at the opposite end of the tube 20, so that this end must be closed, to force the paint to come out of the perforations 22 and moisten the plush 21 of the roller.
- the handle can be adapted to a circular brush, such as the one illustrated in figure 9, where the brush must have a lower internally threaded cavity 28 to be screwed in the tip 26; and therefore it must provide a conduit 79 for the paint to leave the bristles 45.
- a third valve 78 with a nozzle in the shape of a "duck's beak” can be placed, where the nozzle remains Orient ⁇ d ⁇ towards the roller, in order to avoid the return of the paint to the previous components.
- a filter 30 is added, by means of a copy 31.
- the function of the filter 30 is to avoid the entry, to the hose 29, of lumps, cream or any impurity that are in the paint .
- one modality that acquires the present system for painting is that a liquid heater is adapted, especially for geographical regions of low temperatures, for this the liquid heating device is located between the hose section 29 that comes from the paint supply mechanism and the hose end 29 that comes from the container (see figure 26).
- the construction of the liquid heating device is shown in figures 12, 13 and 14, which is constituted by: an external cylindrical tube 32 open on both sides, with both internally threaded ends 34 for threading a copy 35 at each end, forming an internal cavity where an internal tube 33 is housed to form a conduit through which the paint will pass. Between the joints of the inner tube 33 with the copy 35 is sealed with a circular package 37, to prevent the paint from spilling to the outside and prevent the entry of air.
- Said heater comprises electric elements for heating the paint such as a temperature sensor 38, a resistance sensor 39, an electrical resistance 40, temperature control 41 and electric cable 36, which can be placed between the space between the internal cylinder 33 and the external 32, or otherwise suitable for an expert in the field.
- the space formed between the outer tube 32 and the inner tube 33 is filled by insulating material 42, to protect the electrical means and the outer tube 32 is not heated.
- the suction and expulsion chamber already described is inserted in the body 51 of the brush (see figures 15, 16, 17, 18 and 19), so that the lower part of the mechanism is exactly the same, only that the lower extension 5 is more elongated to form part of the handle of the brush; while the upper section 5 'would be the body 51 of the brush.
- the body 51 has in its internal part, above the cavity 1, a conduit 46 with an internal step, where a valve 52 with nozzle in the form of "duck beak” is placed, but with a body different from the aforementioned valves, and that this valve 52 has an annular projection to the middle, which is the part that rests on the top of said conduit 46, thus allowing the passage of the paint towards a removable base 44; whereby said body 51 has in its upper part a longitudinal past channel 43, in which the removable base 44 containing the bristles 45 is inserted.
- the body comprises at one end a safety 47 and at the other end an opening 53, which serve to securely hold the removable base 44.
- the removable base 44 is solid and has a vertical duct 48 for the passage of the paint; where said duct 48 must be in the same position of the duct 46 of the body of the brush, but it has to project outwards and downwards from the base, in the manner of a past tubular projection, so that the nozzle of the valve is inserted therein. 52;
- the tubular projection has an external annular gasket 54 to prevent the paint from coming out in that union.
- the base provides an outgoing-hook 49 in the end where the latch 47 is fastened and at the other end a projection without hook 55 that will be introduced in the opening 53, in this way, the base is fastened to the body of the brush.
- the upper perimetral edge of the removable base 44 projects in thin walls 50, forming a container 51, where a tube passed 56 is inserted in the duct 48, so that the paint comes out; perimetrally and immediately after the thin walls 50 the bristles 45 are embedded but leaving a central space, where first an external plastic bag 57 opened in the upper part is fixed, of lower height than the bristles; then a closed inner bag 58 of lower height than the outer bag 57, with perforations 59 at its upper end; wherein said internal bag 58 supports in its interior and at the height of the tube passed 56 a small bag 60 that covers said tube 56; therefore, the small bag is opened in its lower part and its right side; in such a way that when the paint leaves the tube 56, it disperses towards the other end of the inner bag 58, where the paint comes out through the perforations 59, to be then spilled in the outer bag 57 and finally be distributed towards the bristles Four. Five; achieving with this a uniform and constant flow, throughout the brush
- FIG 27 A variant of the system-brush, is seen in Figure 27, where to the removable base 44, instead of inserting the tube 56, the bristles 45, and the bags 57, 58 and 60, a tube is inserted that supports the a roller, as for example the one described in Figure 8.
- a mechanism that provides vibration is added (Figure 28), which is constituted by a microcircuit 61, with its respective integrated electric translator motor 62, a switch 63 and its respective power source. energ ⁇ 64.
- the arrangement of this mechanism will be at the convenience of an expert in the field, since some parts can go inside or outside, the body and handle of the mechanism supplying paint.
- the vibration mechanism has the purpose of providing vibration to the system for painting, of the present invention, to cause a liquefaction of the paint and to make it flow easily through said system.
- the container or pot containing the paint becomes a portable heater; for this said container must be made of a material resistant to high temperatures, because it will be heated by a resistance 65 that surrounds it externally (Figure 30), which is attached to a cable with electric current 66; a vibration sensor 67 is placed on the pot, which works when there is vibration and interrupts the current for safety; a temperature sensor 68 that interrupts the electric current when the pot is heated from 30 to 60 ° C, so that the paint does not get too hot; a switch 69 of three positions; A flammable and thermally insulating sheath 70 is used to coat the pot with its components and keep it hot longer; and a strap 71 for hanging.
- a fireproof valve 73 was installed, which allows the gases to enter and exit in a controlled manner and prevents the paint from catching fire.
- the threaded cap 74 where the hose 29 is inserted, is designed to be connected to a water outlet 75 and in case the water outlet 75 lacks a thread, then a connector is adapted 76
