Definitions

  • This invention relates to painting rollers especially hand held painting rollers. Discussion of Prior Art
  • One of the problems with painting rollers is the need to frequently dip the roller into a reservoir of paint during the painting operation. In situations where painting is being conducted in very inaccessible places the constant dipping of the roller into the paint is a fatiguing and time consuming exercise which can often result in spillage of the paint.
  • Another problem with painting rollers is that it is important that the right amount of paint is on the roller at a particular time. If there is insufficient paint on the roller, a patchy finish is produced and if there is excess paint on the roller, there is a tendency for the paint to drip from the roller and run back down the roller handle.
  • a painting roller comprising a hollow roller cylinder mounted to be axially rotatable about a rod, the rod supporting a piston urged towards one end of the cylinder by a spring, and a discharge bar positioned externally of the cylinder adjacent the periphery of the cylinder, the discharge bar being in fluid communication with the rod through a discharge control valve whereby in use the movement of the cylinder relative to the rod causes paint to be drawn into the cylinder and forces the piston towards the other end of the cylinder so that opening of the control valve forces the piston to said one end of the cylinder and causes paint to be discharged along the rod and out of the discharge bar onto the periphery of the roller.
  • said one end of the cylinder is provided with a one way valve that allows paint to be drawn into the cylinder as the piston is pulled back against the spring to said other end of the cylinder, the one way valve preventing release of paint as the piston moves in the opposite direction within the cylinder.
  • the rod may possess an aperture adjacent said one end of the cylinder which allows paint to flow from the interior of the cylinder along the length of the rod.
  • an adaptor is detachable to said one end of the cylinder, the adaptor including a length of flexible pipe which in use is dipped into a receptacle of paint to allow the paint to be drawn up into the interior of the cylinder.
  • the other end of the rod is provided with a discharge control valve, said discharge control valve being adjustable to meter the flow of paint from the rod to the discharge bar.
  • An arcuate shield may be positioned adjacent the discharge bar to collect the paint that may fall from either the discharge bar or the paint roller.
  • the position of the discharge bar and/or the position of the shield relative to the periphery of the roller is adjustable.
  • a painting roller comprising a roller cylinder mounted on support means to be axially rotatable thereto, a discharge bar attached to the support means to extend substantially parallel to the roller cylinder in close proximity to the periphery of the cylinder, the discharge bar having paint discharge apertures spaced along the length of the bar or an elongate discharge slot extending along the bar, and discharge means to, in use, propel paint along the discharge bar, out of the discharge apertures and onto the periphery of the roller cylinder.
  • FIG. 1 is perspective view of a painting roller in accordance with one embodiment of the present invention
  • Fig. 2 is a part perspective view of the roller shown in Fig. 1 in the operative position
  • Fig. 3 is a cross-sectional view of a painting roller in accordance with a second embodiment of the invention.
  • Figs. 4 and 5 are end elevational views of the roller of Fig. 3. Description of the Preferred Embodiments
  • FIGs. 1 and 2 of the accompanying drawings illustrate a first embodiment of the invention in schematic form with emphasis being placed on an illustration of the operation of the painting roller without close detail to the engineering of the roller. In contrast in the embodiment illustrated in Figs. 3, 4 and 5 heavier emphasis is placed on the exact design and engineering features of the roller. It is understood that many of the engineering details would be well known to those skilled in this art.
  • Figs. 1 and 2 illustrate a painting roller 10 in the form of a hollow cylinder 11 that terminates in end portions 12 and 13 which are arranged to support a cylindrical hollow rod 14 coaxially of the cylinder.
  • the rod 14 is formed of bent metal or plastics tubing to define two parallel arms 14 and 16 connected by a right angled join 15.
  • the arm 16 is arranged to extend parallel to the cylinder in close proximity to the external periphery of the cylinder 11.
  • a transversely extending joining piece 17 extends mutually perpendicularly to the arm 16 and supports a cylindrical handle portion 18.
  • the cylinder 11 is mounted on the rod 14 to be axially rotatable thereto and in the position shown in Fig. 2 the end 19 of the rod 14 is located in a centrally positioned end cap (not shown) in the end face 13 of the roller.
  • the cylinder 11 is also arranged to be axially displaceable about the rod 14 and the rod 14 has supported thereon a circular piston 30 that is a smooth running fit within the interior of the cylinder 11.
  • the piston 30 is mounted on the rod about a coil spring 33 which acts against the end face 12 of the cylinder to urge the piston 30 to the opposite end 13 of the cylinder.
  • a suitable ring 32 is also mounted on the rod 14 to allow the piston 30 to be displaceable axially relative to the rod 14.
  • the piston 30 is both axially displaceable relative to the cylinder and at times axially displaceable to the rod 14.
  • the end face 13 of the cylinder 11 is also provided with a one way valve 50 that operates to allow flow of paint into the cylinder 11 from the exterior but to preclude return in the opposite direction.
  • the arrangement of the cylinder 11, piston 30 and rod 14 is such that it operates like a syringe.
  • the cylinder In the neutral position the cylinder is located on the rod as shown in Fig. 2 and the piston 30 would be urged by the spring 33 to the end 13 of the cylinder.
  • the rod 14 To draw paint into the cylinder, the rod 14 is pulled out of the cylinder thereby pulling the piston 30 from the end 13 towards the end 12 thereby drawing paint through the one way valve 50 into the cylinder.
  • the ring 32 effectively releases the piston 30 from the rod ensuring that the cylinder 11 can slide along the rod so that the end 19 locates in the end cap 21.
  • the piston still remains to the right of the cylinder as shown in Fig. 1 and is held in this position against the force of the spring 33 by the paint that is contained within the cylinder.
  • the rod 14 is hollow and its free end 19 is provided with a pair of apertures 35 that allows paint to flow along the axial length of the rod through a discharge control device 40 along the right angle bend 15 and through the parallel arm 16 that operates as a discharge bar.
  • the discharge bar is provided with a plurality of equally spaced discharge nozzles 20 so that paint can flow along the rod to be forced out of a discharge apertures 20 onto the surface of paint roller as shown in Fig. 2.
  • the paint roller is shown supporting a conventional fibrous or sponge like cylindrical sleeve 60 that is conventionally used with paint rollers of this kind to apply paint to particular surfaces.
  • the discharge bar 16 supports an arcuate shield 65 that has end plates 66 and 67 to define a paint reservoir underneath the roller sleeve 60.
  • the discharge bar 16 extends through the end plates 66 and 67 and runs along the length of the base of the shield 65.
  • the discharge mechanism 40 is in the form of a outer sleeve 41 that is a close running fit on the rod 14.
  • the rod 14 is provided with a blockage 46 that prevents flow of paint along its length, however, apertures 42 and 47 are provided spaced apart of either side of the blockage 46 and these apertures 42 and 47 communicate with apertures 43 and 48 on the inner surface of the outer sleeve 41.
  • the end face 12 of the paint roller 11 is provided with a plurality of small equally spaced notches 49 into which a series of similarly spaced teeth 45 on the end face of the sleeve 41 of the discharge mechanism can meet.
  • axial rotation of paint cylinder 11 causes a synchronized control of paint release by rotating the discharge sleeve 41.
  • the discharge mechanism allows paint to flow under pressure caused by the force exerted by the spring 33 on the piston 30 to force paint to be released via the discharge bar and nozzles 20 onto the adjacent surface of the roller.
  • the discharge of paint can be carefully controlled and the painting roller has the capacity to paint large areas without having to be constantly dipped into paint as is the case with conventional rollers. Whilst the roller is painting a surface any paint that drips off the roller or the discharge bar 16 is collected in the reservoir defined by the shield 65.
  • a more simplified construction of painting roller is illustrated.
  • the same reference numerals have been used for components described with reference to the first embodiment.
  • the construction has been simplified by doing away with the discharge mechanism 40 of the first embodiment.
  • the operation of the piston has been simplified and the discharge bar 16 is not formed integrally or as a part of the handle 18 and rod 14.
  • a plastics support block 80 supports the major components of the painting roller.
  • the handle 18 is attached to the underside of the block 80 by screws 81.
  • the block includes a fluid passageway 82 that communicates with one end 83 of the discharge bar 16 that is arranged to be secured within the passageway 82.
  • the discharge bar extends in a parallel configuration to the rod 14 of the painting roller as in the first embodiment.
  • the end of the rod 14 is located within a hollow bush 85 that is an integral component of the support block 80.
  • the exterior of the bush 85 is arranged to be a rolling fit about bearings 86 within an end flange 87 that is arranged to be a displaceable fit within the adjacent end of the cylindrical roller 11.
  • An adjustable control valve assembly 90 is positioned on an end face of the block 80 and comprises a screw threaded valve member 91 that can be screwed into a threaded recess in the valve assembly 90 to control the rate of paint flow from the end of the rod 14 into the fluid passageway 82 and thus out into the discharge bar 16.
  • the other end of the cylinder 11 incorporates a one way valve assembly 100 and a male coupling member 101 on which an adaptor 70 of the kind shown in Figure 1 can be attached to allow paint to be drawn into the roller cylinder from a receptacle.
  • the one way valve assembly 100 allows paint to enter the interior of the cylinder but prevents escape of the paint.
  • the piston 120 is supported by a sleeve 121 that is a sliding fit on the rod 14 about an 'O' ring 122.
  • the sleeve 121 supports exterior sealing '0' rings 123 and 124 which are arranged to be a sliding fit within the internal surface of the cylinder 11.
  • a large coil spring 33 is mounted behind a shoulder 126 on the sleeve 121 and is co-axially positioned along the length of the rod 14 to terminate against the end flange 87.
  • the spring 33 urges the piston 120 to the far end of the painting roller that is the end that has the one way valve assembly 100.
  • the one way valve is supported within a location boss 130 comprising a cylindrical support 131 in which the valve assembly 100 is housed.
  • the support 131 merges into the main body 132 that is located to be fixed within the end of the cylinder 11.
  • the main body 132 has at least four spaced apart legs 133 that extend axially of the cylinder to define a bore into which the end of the rod 14 locates when in the position of Fig. 3.
  • Releasing the control valve 90 by turning the screw valve member 91 allows the spring to urge the piston along in the direction of arrow B to force paint to escape through the rod 14 via a bore 140 positioned in an end member 141.
  • the paint then passes through the passageway 82 and into the discharge bar 16 to be released via an elongate discharge slot 138 that tapers to a large cross section towards the end of the cylinder adjacent the one way valve 100.
  • the operation can be repeated so that the painting roller is filled with more paint.
  • the exterior of the roller sleeve 60 runs within the reservoir formed by the shield 65 and also runs directly on the external periphery of the discharge bar 16. In this way, there is intimate contact between the discharge slot 138 in the discharge bar 16 and the periphery of the roller sleeve 60. Furthermore, paint that drips down from the roller or discharge bar to be collected in the reservoir defined by the sleeve 65 can be picked up by the periphery of the roller to be used in the usual manner. Thus, the assembly is very clean and is unlikely to cause dripping or spillage of paint.
  • the sleeves that are used on paint rollers vary in thickness depending on the type of paint that is being used and the desired paint finish. Since the thickness of sleeves vary, it is important that there is some adjustability between the distance between the discharge bar and the sleeve. This adjustability also affects the position of the shield and the cylinder. Although not shown in the drawings, the adjustability will be provided in the end block 80 and so that the assembly could be used with a variety of paint roller sleeves.
  • a further feature not shown in the drawings that could be incorporated into the assembly described above is the provision of a hand releasable trigger that would control operation of the paint release valve 90. This would allow the user of the assembly to have a more positive control of the rate of paint release whilst holding the handle 18 of the roller.
  • the painting roller described provides a number of advantages.
  • One major advantage of the preferred embodiment is the capacity for the roller to store a quantity of paint which will allow a large area to be painted without having to dip the roller into a source of paint.
  • a further important feature of the painting roller described above is the means by which the paint is discharged onto the roller surface.
  • the use of a discharge bar with a series of discrete discharge apertures adjacent the periphery of the roller allows a smooth and uniform application of paint to the roller. This makes the roller easy to use and improves the quality of the paint finish.
  • the roller has also been designed for ease of cleaning.
  • the use of the roller and discharge bar provides a capacity for other means of discharging paint.
  • An electric motor could be housed in the handle of the roller and this could be powered by batteries which could be rechargeable.

Abstract

Un rouleau à peinture comprend un rouleau cylindrique creux (11) monté de façon à pouvoir tourner axialement autour d'une tige (14), la tige supportant un piston (30) qui est forcé vers l'une des extrémités du cylindre par un ressort (33). Le rouleau à peinture comprend également une barre de décharge (16) positionnée à l'extérieur du cylindre adjacente à la périphérie du cylindre, le passage de fluide étant assuré entre la barre de décharge et la tige par l'intermédaire d'une valve de commande de décharge. Grâce à cette dernière, lors du fonctionnement, le mouvement du cylindre par rapport à la tige entraîne le passage de la peinture vers le cylindre, forçant le piston vers l'autre extrémité du cylindre de telle sorte que l'ouverture de la valve de commande force le piston vers ladite extrémité du cylindre et provoque la décharge du fluide le long de la tige et sa sortie de la barre de décharge et vers la périphérie du rouleau.
