Definitions

  • the present invention relates to a device for roller painting.
  • the present invention relates to a device for roller painting especially suitable for being used for works of painting/decorating at the corners of a wall or of the ceiling of rooms or spaces inside and/or outside civil and/or industrial contexts.
  • the painting/decorating of inside or outside spaces for civil or industrial use is typically performed by using brushes or rollers soaked with paint in the colour and in the finishes most suitable for the decorative and coverage effect required for the specific room.
  • the sizes and types of brushes and/or rollers vary as a function of the sizes and of the position of the wall or of the elements (doors, frames, radiators, etc.) which have to be painted.
  • a typical case is represented by the painting or varnishing of the corner areas between two adjacent walls or between ceiling and walls, to perform which it is possible to use a flat brush with straight or oblique head or a paint brush with round head or, alternatively, a sponge or fabric roller (according to the type of finish to be obtained and/or the surface features of the wall).
  • the use of the paint brush requires a great deal of time and effort in that it is necessary to dip it repeatedly to keep it loaded, with continual movements of ascending and descending the ladder or, in any case, in the direction of the bucket or container with the paint.
  • a further disadvantage linked to the use of the paint brush is represented by its dripping if overly loaded with paint and, consequently, by the unevenness of the finish.
  • roller always has a projecting pin or projecting rod (to support the rotation of the roller) which creates lines on the wall, requiring subsequent further strokes, optionally with a paint brush, in order to be able to eliminate them.
  • a further disadvantage is represented by the fact that the painted band which is obtained with the roller or with the paint brush is very narrow in that, if a roller or a paint brush of greater dimensions were to be used it would not be possible to perform easily and completely/evenly the painting of the intersections of the corners of the walls with the ceiling or between adjacent walls and it would then be necessary to finish the painted part with a further appropriate paint brush with a correlated increase in terms of time, dripping and the like. Moreover the use of a roller of larger size compared to those typically present on the market for the specific function would worsen the disadvantage represented by the pin mentioned above.
  • a painting device comprising a container element with respect whereto two painting rollers are rotatably arranged with V-sectioned profile and whose sides engage with a feed roller, likewise rotatably arranged inside said container element, partially immerged in a receptacle of paint integrated with the container element and with a V-sectioned profile complementary to the V-shaped profile of the painting rollers.
  • a rod hinged with respect to the container element allows the painting device to be moved and orientated.
  • the main object of the present invention is that of avoiding the disadvantages mentioned above.
  • the object of the present invention is that of providing a device for roller painting which allows painting to be performed with bands of adequate width of the corner regions between adjacent walls and between walls and ceiling rapidly and easily.
  • a further object of the present invention is that of providing a device for roller painting which does not create splashes or drips of paint during painting.
  • a further object of the present invention is that of providing a roller device which allows application of the paint evenly and without residues of drips, lumps or similar imperfections.
  • a further object of the present invention is that of providing a device for painting of the roller type with limited overall dimensions and such as not to have elements which can create interference with the surfaces during painting.
  • a further object of the present invention is that of making available to users a device for roller painting suitable for guaranteeing a high value of resistance and reliability in time and such, moreover, as to be able to be easily and economically manufactured.
  • a device for roller painting comprising a first roller or front roller rotatably arranged with respect to a first axis and a second roller or rear roller rotatably arranged with respect to a second axis with said first and second axes parallel one to the other, a shell or casing partially covering said first and second rollers, a rod attached to said shell or casing and with the first roller and the second roller shaped with a convex conical profile.
  • the device for roller painting of the invention comprises a first roller or front roller 12 rotatably positioned with respect to a first axis 14 and a second roller or rear roller 16 rotatably positioned with respect to a second axis 18, with said first axis 14 and second axis 18 arranged parallel one to the other and with said first and second rollers secured internally to a shell or casing 20 defined by a single part or by separate components assembled one with the other by gluing, slotting, welding or the like and known means of constraint and made in lightweight, resistant and easily washable plastic material.
  • the first roller 12 and the second roller 16 have tendentially different dimensions in terms of thickness in the direction of the rotation axis, diameter and a convex conical profile.
  • the first roller or front roller 12 has a thickness tendentially comprised between 2 and 3 cm, while the second roller or rear roller 16 has a thickness tendentially comprised between 3 and 6 cm.
  • the conical profile of the first roller 12 defines an angle ⁇ smaller than 90° while that of the second roller 16 defines an angle ⁇ greater than or equal to 90°.
  • the angle ⁇ is for example comprised between 45 and 80° and preferably equal to 60°, while the angle ⁇ is for example comprised between 90 and 110° and preferably equal to 95°.
  • Both the first roller or front roller 12 and the second roller or rear roller 16 are made in sponge, velvet, in natural or synthetic material or in other different and suitable materials and finishes chosen according to the type of wall to be painted or paint used or, again, the final effect required.
  • the first roller or front roller 12 is a painting roller and has the function of painting the corner of the wall and the edge comprised between the intersections of the walls and of the ceiling. This is allowed by the fact that said first roller has an angle of the conical profile smaller than 90° and a width smaller than that of the second roller 16.
  • the second roller or rear roller 16 instead, has a smoothing and levelling function in that it allows more even application of the layer of paint deposited by means of the first roller and, having greater thickness compared to that of the first roller12, allows the dimension of the painted angular band to be increased so as to allow then the use of a roller or paint brush suitable for painting large surfaces.
  • the shell or casing 20 comprises a front portion 22 partially covering the first roller or front roller 12 and a rear portion 24 partially covering the second roller or rear roller 16.
  • the internal configuration and, optionally, also the external one of the front portion 22 and of the rear portion 24 of the shell or casing 20 is made with a shaping with conical profile corresponding to that of the two rollers, in such a way that the splashes or nebulised particles of paint, generated by the rolling of the rollers on the surface to be painted, are collected in the gap formed between the front and rear portions of the shell or casing and the respective front and rear rollers.
  • the front portion 22 and the rear portion 24 are joined below by means of opposed plate-like projections 23 which define a lower face or base of the shell or casing 20 arranged along a plane parallel and positioned above with respect to the plane whereon the rotation axes of the first roller 12 and of the second roller 16 lie.
  • a stop element or block 32 is placed for the rod 30 apt to provide a mechanical slotted constraint of the snap-fit type or with deformation or a magnetic constraint.
  • This stop element 32 has the function of blocking the movement of the rod 30 during the phase of loading of the rollers with paint according to the methods described here below.
  • hinge connection of the rod 30 with respect to the fork 26 of the shell or casing 20 can be of the damped type so as to allow the locking of the movement of the same rod in any angular position.
  • the device for roller painting is typically coupled to a tray assembly for painting roller (not shown in the drawing) suitable for allowing the loading of the roller device with paint.
  • This tray assembly for roller is substantially similar to the one described in a previous European patent application (EP2452828 ) in the name of the same Applicant and, therefore, will not be described in detail with reference to the constructional elements and to the modes of operation.
  • the tray assembly for roller has a paint collection tray apt to collect a quantity of paint coming from a receptacle integrated in the same tray assembly in a sufficient quantity for impregnating the rollers without the need to remove the surplus paint and provided with a groove or recess longitudinally extended and with a "U” or "V " cross-sectional profile substantially corresponding to the profile of the first roller 12 and of the second roller 16.
  • the device for painting with conical rollers of the invention is, at this point, ready to be used at the corners between adjacent walls and between walls and ceiling.
  • the device for painting with rollers of the present invention being provided with conical rollers, allows advantageously the painting in a short time of the corner portions between adjacent portions and/or between walls and ceiling of a room for civil or industrial use, without soiling and without unfortunate dripping.
  • rollers with conical profile allow easy access to the corner portions of the walls without the need to use a paint brush for finishing operations.
  • the second roller or rear roller having a thickness substantially greater with respect to that of the first roller, allows the painted band at the corners to be increased and, consequently, makes the use of the roller for painting the wall faster and easier.
  • a further advantage is represented by the fact that the front portion 22 of the shell or cover 20 covers only partially the first roller or front roller 12 and, more specifically, develops with a covering angle smaller than 90°. In this way the front roller easily reaches the edges between the walls and the ceiling.
  • a further advantage is represented by the fact that the device of the invention does not have pins or laterally projecting parts such as to be able to come into contact with the walls with consequent unfortunate forming of lines which have to be subsequently eliminated using a paint brush.
  • the position and the shaping of the covering casing or shell contribute to avoiding this unfortunate disadvantage.
