Definitions

• the object of the invention is a device to clean painting rollers from a paint.
• Such rollers are a piece of equipment used to paint different surfaces.
• the roller is used to pick up a suitable quantity of a paint from a container and next to cover with this paint - by means of the roller rotation - surfaces intended to be painted. After painting, not to let the paint to dry out, the rollers are directly cleaned in manual way by means of squeezing and twisting off the outer, paint absorbing coating under a steam of warm water. Due to a direct contact of a person with a paint and frequent application of cold water, the cleaning is unpleasant and toilsome process.
• Different kinds of open-work or solid plates with convexities are known, e.g. according to the patent application no P 311 199, the plates are assigned to scrap an excessive amount of paint to uniformly distribute a suitable quantity of a paint on the roller before painting process of an intended surface. Using multiple rubbing of the roller on the scraping plate, it is possible to remove under the pressure only a small quantity of the paint into the container. However it hardly influences on the shortening of the manual cleaning process under the water stream.
• the aim of the invention is to design a device which could facilitate the cleaning of the painting rollers from a paint to reach high efficiency of cleaning with limited water waste.
• a device has been designed, which contains a paint scraping segment with an arc-shaped surface from the inner side, adjusted to the roller's diameter, fixed to the handle. Additionally, both sides of the arc-shaped surfaces are chamfered.
• the scraping segment is fixed to the handle in stiff or in separable way. From the outer side it also has the arc-shaped recesses, adjusted to the cleaning elements of the painting devices with smaller oval cross-sections.
• a cleaning brush is fixed to the handle from the other side of the segment.
• the object of the invention is shown as an exemplary model in figures, where: fig. 1 represents the device in a partial, longitudinal section, fig. 2 - magnified lower part of the device in separated position, in a vertical section, fig. 3 - lower part of the device in top view, fig. 4 - scraping segment of the device in top view, fig. 5 - the device with the painting roller and the cleaning device in working position, in a perspective top view.
• the device consists of exchangeable scraping segments 2 and brush 3 fixed to the handle L
• the handle I is produced of steel rod of oval cross-section.
• a grip 4 In the upper part of the handle, on its straight or bent part there is placed a grip 4.
• the bent tip In the lower part of the handle, the bent tip is ended with quadrangular pivot 5, in which, on the side there is a seat 6 for the screw 7 which fix the segment.
• a threaded hole 8 for screw 9 used to fix the brush 3 on the other side of the segment near to the bent area in the handle.
• the segments 2 have on the inner side arc-shaped surfaces J_0, adjusted to a diameter of the painting roller.
• the recess ⁇ is assigned to clean the handle rod, and recess Y2 to clean a small roller, frequently used by professional painters.
• the arc-shaped inner surfaces have on both sides chamfers Y3_ of the front edges, facilitating guiding of the device and removing of a paint during the roller cleaning process due to decreasing of the friction.
• the front edges of the recesses J and Y2 also have the chamfers L4 and L5.
• the segment 2 has a seat J_6 of quadrangular cross-section, adjusted to shape of a handle pivot.
• the best vertical bending angle for the seat is from 10° to 20°. It assures proper position of the handle I with relation to the segment and facilitates manipulation of the device during the roller cleaning process.
• the segment 2 is a art of a ring, or profitably semi-ring and it is made of plastic or metal.
• the segment can be fixed to the handle in separable way by means of a simple screw connection, or other known connection solutions.
• the handle and the segment are connected in separable way.
• Several exchangeable segments, adjusted to the diameters of painting rollers frequently used by professional painters are included into the set of the device.
• the scraping segment with inner diameter should be more or less equal to the outer diameter of the stiff part of the roller, where in most cases there is a coating made of textile fibres material which absorb liquids.
• the side surfaces of the roller are cleaned by means of the brush 3, placed on the opposite side of the scraping segment, the handle rod is cleaned by means of putting it in smaller recess U . of the segment.
• a brush is used to clean the elements of painters equipment which are hard to reach.
• the device eliminates usage of warm water during the cleaning process and simultaneously decrease usage of cold water with comparison to the traditional method which is based on manual cleaning by means of squeezing and twisting off the outer, paint absorbing coating under a steam of warm and/or cold water.
