DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The invention relates to a device for cleaning paint brushes or the like.
Such a device is known from German patent 37 25 093. In this known device the wiping elements consists of thin needles provided at a rather large mutual distance. Although these needles penetrate between the bristles of the paint brush, the cleaning action of the needles leaves much to be desired.
U.S. Pat. No. 4,387,477 discloses a paint roller cleaning system having a container with a plurality of wiping elements made as helical coil members formed of wire with a diameter of 3 mm. The helical coil members are mounted lying in the container.
SUMMARY OF THE INVENTION
The invention-aims to provide a device of the above-mentioned type, wherein the cleaning action of the wiping elements is improved.
To this end the apparatus according to the invention is characterized by the characterizing features of claim 1.
Thereby it is obtained that at least a part of the wiping elements is provided with scraping edges which, so to say, scrape the paint residue and the like off of the bristles of the paint brush when the paint brush to be cleaned is moved along the wiping elements. In this manner an excellent cleaning action is obtained. This shape of the wiping elements provides sharp edges acting as scraping edges and can be manufactured relatively simply. Preferably each wiping element has a polygonal, preferably rectangular cross section at its end adjacent the bottom and tapers from the bottom. The device of the invention allows efficient cleaning of the paint brush with a minimum amount of cleaning fluid.
In order to obtain an optimal cleaning action of the wiping elements it is advantageous according to the invention that the wiping elements are arranged in such a pattern that in two mutual perpendicular directions successive wiping elements are aligned alternatingly with their long and short side, respectively, in the respective direction.
The application possibilities of the device can be increased if the device further comprises clamping means for suspending paint brushes and a cover for closing the container.
In practice the use of the known device has a further disadvantage in this respect that the user has no suitable means available for removing used cleaning fluid and paint residue remaining in the container.
The invention aims to provide a solution for this problem too by providing an assembly for cleaning paint brushes or the like, said assembly comprising the described device of the invention together with a refuse container and a cover for closing the refuse container, wherein the cover and/or refuse container comprises at the inner side an upright edge for holding the container.
In this manner an assembly is obtained, wherein the device is suitable for multiple use whereas the refuse container and the corresponding cover can be made for single use so that the refuse container closed by the cover and filled with the used cleaning fluid and paint residue can be offered as chemical waste.
The invention will be further explained hereinafter by reference to the drawings in which some embodiments of the device and the assembly according to the invention are shown.
