Abstract
The invention relates to a mechanism for efficiently supplying paint to a roller or brush, formed by a suction/discharge pump including a deep cavity (1). The pump includes two externally threaded cylindrically-hollow extensions (5 and 5′) which are located diagonally opposite one another in relation to the cavity (1) and serve as connectors for attaching accessories, such as, for example, a brush, roller handle or hose. The lower extension (5) includes a narrow channel (7) which is connected to the cavity (1) and the other end of which is connected to a wide channel (6) into which is inserted a first valve (8) having a duckbill-shaped nozzle, made from a deformation-resistant material. The upper section (5′) has a similar structure to the lower section (5), but differs in that, instead of having a wide channel (6), this section ends in a tip (15) of equal thickness to that of the wide end (9) of the male connector, so that a second valve (8′) having a duckbill-shaped nozzle can be mounted thereon.
Description
- The present invention relates to the technical field of building, specifically to the finishing steps: it provides a system to deliver pain to a brush or a roller.
- One of the problems that have arisen in the activity of painting buildings is the fact that the paint is thick, viscous and of a sticky consistency similar to honey, and therefore when dried stick in pieces and block ducts. It has a volatile chemical which tends constantly to create clot, grease and lump. Even when being filtered properly, paint can clog pipes at any time, either while being applied, or especially, when left at rest.
- U.S. Pat. No. 1,829,850 explains new and useful improvements in brushes and particularly with a brush which is provided continuously a liquid or a solution coming from an attached container. The main problem of these pressure systems is that the consistency of the paint is uneven, if there is a clot stuck, when you open the valve that regulates the paint output, only a small trickle is injected, but then when the clot or lump of paint is released a burst of paint in ejected, besides this, the pressure in the paint container is not constant, nor is the difference in height between the container and the brush, which constantly rises and falls. Consequently, the painter has no control over the paint injected and can cause excessive runoff, so these systems work satisfactorily for rollers, which can hold inside significant amount of excess paint, while releasing little by little, it also work with a sprayer that spreads the paint directly on the paint surface. But it does not function properly with a brush, as the excess amount of paint that can be absorbed is minimal. Any excess which exceeds the capillary capacity of the bristles will spill.
- U.S. Pat. No. 2,932,043 describes a mechanism for applying paint with four functional components, one being a spring in the exit valve, where there is force and where pressure is not critical, but it strengthens the seal at the top which is why where air can leak and remove the spring on the entrance valve, where what matters is the strength and not the seal. Even though it's a single spring, it is susceptible to corrosion. It also explains how its “check” valve can be disassembled and cleaned, but not in their internal parts to be assured that they leave no leaks and stay firmly secured, meaning that the internal part valves is inaccessible to wash. In addition, the spring, being thin and made of steel, is very susceptible to corrosion or cannot be replaced. Another disadvantage is that the suction pump lacks strength, but the inventor does not use a spring in the entrance valve, which would add suction strength and even if he explains that his pump have a sufficient strength to return to its original position and suction a thick fluid, this cylindrical design is simply inadequate to exert a significant suction force.
- The patent application PCT/MX2006/000076 describes a paint supplying system for a brush or a roller, which have the following disadvantages: A difficult cleaning as a lot of paint gets stuck in the tubes and valves of the spring, the assembly of the upper and lower parts is very time consuming due to their shape and the model is very rustic, additionally the way in which the paint is distributed to the bristles is very slow and it takes time to distribute it correctly on the bristles of brush.
- In order to eliminate all the mentioned inconvenient, a new improved painting system was developed that include means to efficiently deliver the painting, while also makes a strong emphasis on the versatility of uses and on the possibility to wash it. This invention allows to paint with an easy and continuous flow of paint in the bristles of the brush or plush of the roller, which I describe below.
- The detailed characteristics of the present paint supply system to a paintbrush or a roller brush, which are described below and illustrated by the drawings, are cited as an example and should not be considered as limitative.

- A suction/expulsion pump to deliver the paint to a roller or brush, which in turn comprises an
open cavity 1, preferably circular, similar to the one described in the patent application PCT/MX2006/000076, but with the difference that thiscavity 1 is more profound (FIGS. 3 and 5 ) to provide more paint. Thecavity 1 is hermetically sealed with a circular lid formed by a circularelastic membrane 2 whoseperimeter 3 is thickened and strengthened so as to form a sort of ring, which is pressed into achannel 4 located on the upper outer part and which surrounds thecavity 1. Optionally, the cover has atongue 2′ on its side, used to pull and remove the cover from thechannel 4 that surrounds thecavity 1; so thatchannel 4 has asmall cavity 4′ which holds thetongue 2′. - The
cavity 1 has two externally striated and threadedextensions - The
lower extension 5 has anarrow channel 7 which is connected to the depression ofcavity 1 and have its other end attached to awide channel 6 where is introduced afirst valve 8 with a duckbill-shaped nozzle, made of an elastic material and resistant to deformation. Thisfirst valve 8 is mounted on thewide end 9 of a male connector shaped in an arrow form, so that in thewide channel 6 stay fixed saidfirst valve 8 and the wide end of theconnector 9, the nozzle being oriented towards thenarrow channel 7, to allow the introduction of paint into the cavity of the pump. Theother extremity 11 of the male connector is thinner and ends in an arrowhead, which is inserted into thenarrow channel 13 of aremovable piece 12 until theupper limit 10 of the male connector reaches the internal step of theremovable piece 12; so it is clear that said removable piece is an open cylinder, which interior denotes two sections, the already mentionednarrow channel 13 and anupper channel 14 which is wider and internally threaded, to receive the external thread of thelower extension 5 so both parts stay assembled. - The
upper extension 5′ of the paint supplying system, if similar in construction to thelower extension 5, with the difference that instead of having awide channel 6, this one is ending in atip 15 of equal thickness than the extreme width of themale connector 9, so that can be mounted asecond valve 8′ with a duckbill-shaped nozzle, once mounted thevalve 8′ is inserted into thecavity 16 of an arrow shaped female connector, whosetip 18 is inserted in a second removablecylindrical piece 12, until itslimit 17 makes contacts with the internal step of said removable piece. - In this case the
second valve 8′ stays oriented towards the arrow-shapedtip 18, in such a way as to allow the output of paint to the painting device. - The pieces described must have a construction that allows an hermetically assembly between said pieces, see
FIGS. 2 and 3 ; but if necessary you can add aring gasket 19 for this purpose. - In this way we have a mechanism that provides paints efficiently to the painting devices, since its suction/expulsion chamber is sealed and deeper, which allows a greater supply of paint, compared with the mechanisms already known. The pump works by applying pressure on the
elastic membrane 2, if thecavity 1 is filled with paint, it tends to leave through thechannel 7 of theupper extension 5′, passing through theexit valve 8′, to thepoint 18 of the female connector; when stopping to apply pressure on themembrane 2, it reverts back to its normal state, so it makes the cavity being refilled by paint coming from a container or pot which enters through the male connector, passing through thenentry valve 8 into thecavity 1. Therefore, the mechanism must be sealed tightly, so vacuum is created and having only paint circulates inside. - This mechanism can be adapted to painting devices who self-supply themselves with this liquid, more specifically, rollers or brushes. I will proceed to detail some examples of application of this mechanism.
- In the case of a roller, it is necessary to implement a handle to hold the roller (
FIGS. 6 , 7 and 8), where said handle is formed of acylindrical body 24, preferably, inside which pass through aconduit 77 to allow the passage of paint, its upper extremity ends in an externally threadedbushing 26 for threading it with an internally threadedcap 27, and its inferior extremity terminates in an arrow-shapedtip 25 to have it connect to aflexible tube 29 which in turn is connected to the paint supplying mechanism described above. The threadedcap 27 has acentral perforation 23, where it inserted the open end of atube 20 which hold theroller plush 21, to have the paint continue his way through saidtube 20 until exiting through a series ofsmall perforations 22 which are located at the opposite end of thetube 20, so this tip should be closed, to force the paint to go out through theholes 22 and then moisten the plush 21 of the roller. - To the handle can be adapted a circular brush, as illustrated in
FIG. 9 , where the brush must have an internally threadedlower cavity 28 to be screwed into thetip 26, and therefore must provide aconduit 79 to allow the paint to exit through thebristles 45. - At the junction of the threaded
cap 27 and the upper threadedend 26 of thebody 24 of the handle can be placed athird valve 78 with a duckbill-shaped nozzle where the nozzle stay oriented towards the roller, in order to prevent the return of the paint to the components mentioned above. - In the inferior part of the paint supplying mechanism is added another stretch of
flexible tube 29 exactly at the arrow tip of themale connector 11, which in turn connects to a conventional paint container paint (FIG. 11 ), where is added afilter 30 to the end of theflexible tube 29 that goes into the container, by means ofcopy 31. The function of the filter b is to prevent the entry in theflexible tube 29 of clots, lumps or any impurities that can be found in the paint. - In order to maintain an efficient supply of paint, an embodiment acquired by the present paint system is that is added a liquid heater, especially in geographic regions of low temperatures, for this, the liquid heater device is located between the stretch of the
flexible tube 29 coming from the paint supply mechanism and the end of theflexible tube 29 coming from the container (seeFIG. 26 ). - The construction of the liquid heater device is shown in
FIGS. 12 , 13 and 14, it is constituted of: an outercylindrical tube 32 open at both ends, with both ends 34 internally threaded to screw acopy 35 on each extremities, forming an internal cavity which houses aninner tube 33 passing through to form a conduit through which pass the paint. Between theinner tube 33 junction withcopy 35 is sealed with acircular package 37, to prevent the paint from spilling and prevent outside air from entering. Said heater includes electrical elements to heat the paint such as asensor 38, aresistance sensor 39, anelectrical resistance 40, atemperature controller 41 andelectric cables 36, which can be placed between the space between the innercylindrical tube 33 and outercylindrical tube 32, or in another way suitable to a person skilled in the art. The space formed between theouter tube 32 andinner tube 33 is filled by insulatingmaterial 42, to protect the electric components and to prevent the heating of theouter tube 32. - Now, in the case of a paint brush, the suction/expulsion chamber described above, is inserted into the
body 51 of the brush (seeFIGS. 15 , 16, 17, 18 and 19), so the lower mechanism is exactly the same, except that theinferior extension 5 is longer in order to be a part of the handle of the brush, while theupper section 5′ forms thebody 51 of the brush. Thebody 51 has in its internal part, on thecavity 1, achannel 46 with an internal step, where is located avalve 52 with a duckbill-shaped nozzle, but with a different body than the valves already mentioned, as thisvalve 52 have a circular ledge in the middle, which is the part that rests on top of saidchannel 46, thus allowing the passage of the paint to adetachable base 44, so that saidbody 51 has in its upper part alongitudinally passing channel 43, where is inserted thedetachable base 44 which contains thebristles 45. - The body includes at one of its extremity a
fastener 47 and on the other end anopening 53, which serve to hold firmly to thedetachable base 44. - The
detachable base 44 is solid and has avertical channel 48 for the passage of the paint; where saidchannel 48 must be in the same position as thechannel 46 of the body of the brush, but have to be projected out and down from the base, by way of a transversal tubular ledge, so that can be inserted in it the nozzle of thevalve 52; the tubular ledge has anouter ring gasket 54 to prevent the paint from coming out of this junction. - The base provides an
outgoing hook 49 on the end where it is to secure the safe 47 and at the other end a ledge withouthook 55 to be inserted into theopening 53, thus the base is securely fastened to the body of brush. - The upper perimeter edge of the
detachable base 44 projects intothin walls 50, forming acontainer 51, where atube 56 is inserted into theduct 48, to have the paint exit; on the perimeter and immediately after thethin walls 50 are mounted thebristles 45 while leaving a central space, where is first attached an outerplastic bag 57 opened in its superior part, and of a lower height than the bristles; then is placed a closedinner bag 58 of a lower height than theouter bag 57, withperforations 59 in its upper end, where saidinner bag 58 holds in its interior and at the same height than thetube 56, asmall bag 60 which covers saidtube 56; so the small bag is open at its bottom and right side; therefore when the paint come out of thetube 56, it disperses to the other end of theinner bag 58, where the paint goes out through theperforations 59, before being poured into theouter bag 57, and finally be distributed to thebristles 45, achieving this way an uniform and constant flow throughout the whole brush. - A variant of the brush system is shown in
FIG. 27 , where to thedetachable base 44, instead of having inserted in it thetube 56, thebristles 45 and thebags FIG. 8 . - To the present system and all its variants can be optionally added a mechanism that provides vibration (
FIG. 28 ), which is made up of acircuit 61 with its respectiveelectric motor 62, aswitch 63 and itsrespective power source 64. The disposition of this mechanism shall be to the convenience of one skilled in the art, as some components may be placed either inside or outside the body and the handle of the paint supplying mechanism. The vibration mechanism is intended to provide vibration to the painting system of the present invention, to cause a liquefaction of the paint in order to make it flow easily through the system. - To heat the paint, the following embodiment can also be used: the container or pot containing the paint becomes a portable heater, for that said container must be of a material resistant to high temperatures, because it will be heated by a
resistor 65 that surrounds it externally (FIG. 30 ), which is connected to apower cable 66; on the container is placed on avibration sensor 67 which detect the presence of vibrations and then shut off the power for safety, atemperature sensor 68 that interrupt the electrical current when the container is heated from 30 to 60° C., so that the paint do not overheat, a three-position switch 69, an inflammable and thermally insulatedsleeve 70, used to cover the container components and keep it warm longer; and astrap 71 for carrying it. - In the
cap 72 of the container is implemented afireproof valve 73 which allows the entrance and exit of gases to be regulated in a controlled manner and prevents the paint to ignite. - For the cleaning or washing of the present system, the threaded
cap 74, where is inserted theflexible tube 29, is designed to connect to awater faucet 75 and if thewater inlet 75 is not threaded, then aconnector 76 can be adapted.

The body 51 has in its internal part, on the cavity 1, a channel 46 with an internal step, where is located a valve 52 with a duckbill-shaped nozzle, but with a different body than the valves already mentioned, as this valve 52 have a circular ledge in the middle, which is the part that rests on top of said channel 46, thus allowing the passage of the paint to a detachable base 44, so that said body 51 has in its upper part a longitudinally passing channel 43, where is inserted the detachable base 44 which contains the bristles 45. The body includes at one of its extremity a fastener 47 and on the other end an opening 53, which serve to hold firmly to the detachable base 44, which is solid and has a vertical channel 48 for the passage of the paint; where said channel 48 must be in the same position as the channel 46 of the body of the brush, but have to be projected out and down from the base, by way of a transversal tubular ledge, so that can be inserted in it the nozzle of the valve 52; the tubular ledge has an outer ring gasket 54 to prevent the paint from coming out of this junction.
The base provides an outgoing 49-hook on the end where it is to secure the safe 47 and at the other end a ledge without hook 55 to be inserted into the opening 53, thus the base is securely fastened to the body of brush. The upper perimeter edge of the detachable base 44 projects into thin walls 50, forming a container 51, where a tube 56 is inserted into the duct 48, to have the paint exit; on the perimeter and immediately after the thin walls 50 are mounted the bristles 45 while leaving a central space, where is first attached an outer plastic bag 57 opened in its superior part, and of a lower height than the bristles; then is placed a closed inner bag 58 of a lower height than the outer bag 57, with perforations 59 in its upper end, where said inner bag 58 holds in its interior and at the same height than the tube 56, a small bag 60 which covers said tube 56; so the small bag is open at its bottom and right side; therefore when the paint come out of the tube 56, it disperses to the other end of the inner bag 58, where the paint goes out through the perforations 59, before being poured into the outer bag 57, and finally be distributed to the bristles 45, achieving this way an uniform and constant flow throughout the whole brush.
8. A mechanism to efficiently deliver paint to a roller or a brush, as claimed in claim 7 , where to the mechanism is inserted, in the channel 46, a tube that holds a roller, as described in claim 4 , instead of inserting the detachable base.
9. A mechanism to efficiently deliver paint to a roller or a brush, as claimed in the previous claims, characterized in that to its inferior part is added another stretch of flexible tube 29 exactly at the arrow tip of the male connector 11, which in turn connects to a conventional paint container paint, where is added a filter 30 to the end of the flexible tube 29 that goes into the container, by means of copy 31, to prevent the entry of lumps or any impurities that can be found in the paint.
10. A mechanism to efficiently deliver paint to a roller or a brush, as claimed in claim 9 , characterized in that is added a paint heater, between the stretch of the flexible tube 29 coming from the paint supplying mechanism and the extremity of the flexible tube 29 coming from the container. Said heater is constituted of: an outer cylindrical tube 32 open at both ends, with both ends 34 internally threaded to screw a copy 35 on each extremities, forming an internal cavity which houses an inner tube 33 passing through to form a conduit through which pass the paint. Between the inner tube 33 junction with copy 35 is sealed with a circular package 37, to prevent the paint from spilling and prevent outside air from entering. Said heater includes electrical elements to heat the paint such as a sensor 38, a resistance sensor 39, an electrical resistance 40, a temperature controller 41 and electric cables 36, which can be placed between the space between the inner cylindrical tube 33 and outer cylindrical tube 32, or in another way suitable to a person skilled in the art. The space formed between the outer tube 32 and inner tube 33 is filled by insulating material 42, to protect the electric components and to prevent the heating of the outer tube 32.
11. A mechanism to efficiently deliver paint to a roller or a brush, as claimed in claim 10 , characterized in that the container or pot containing the paint becomes a portable heater, for that said container must be of a material resistant to high temperatures, because it will be heated by a resistor 65 that surrounds it externally, which is connected to a power cable 66; on the container is placed on a vibration sensor 67 which detect the presence of vibrations and then shut off the power for safety, a temperature sensor 68 that interrupt the electrical current when the container is heated from 30 to 60° C., so that the paint do not overheat, a three-position switch 69, an inflammable and thermally insulated sleeve 70, used to cover the container components and keep it warm longer; and a strap 71 for carrying it.
In the cap 72 of the container is implemented a fireproof valve 73 which allows the entrance and exit of gases to be regulated in a controlled manner and prevents the paint to ignite.
12. A mechanism to efficiently deliver paint to a roller or a brush, as claimed in the previous claims, characterized in that is added a mechanism that provides vibration, which is made up of a circuit 61 with its respective electric motor 62, a switch 63 and its respective power source 64. The disposition of this mechanism shall be to the convenience of one skilled in the art, as some components may be placed either inside or outside the body and the handle of the paint supplying mechanism. The vibration mechanism is intended to provide vibration to the painting system of the present invention, to cause a liquefaction of the paint in order to make it flow easily through the system.
13. A mechanism to efficiently deliver paint to a roller or a brush, as claimed in the previous claims, characterized in that the threaded cap 74, where is inserted the flexible tube 29, is designed to connect to a water faucet 75 and if the water inlet 75 is not threaded, then a connector 76 can be adapted.
