The invention relates to an arrangement in painting tools, called rollers or paint rollers, having a tubular part, the outer surface of which is provided with a material suitable for applying paint and having a certain flexibility and absorbency, for example lamb's wool or artificial material, in addition to an axis around which the roller can rotate freely. inside the tubular part, whereby one end of the shaft acts directly or indirectly as a handle and its other end cooperates with a plate arranged outside the free end of the roll.

Painting tools such as those disclosed are known from the patent literature, for example from U.S. Patent Nos. 3,685,084, 3,623,180 and 3,378,872. However, these known tools have a number of disadvantages for both professionals and amateurs, in which case, for example, the end plates of these tools alone are intended to act as an intermediate member and thus to protect the nearby wall from unwanted painting. To that end, the desired action should only be achieved in a short time »due to the fact that the tile is arranged immobile. The wear of the spreading surface causes the lower edge of the tile to be against the substrate relatively quickly, but on the other hand the part of the paint roller closest to the tile stops working completely because the spreading surface does not touch the substrate. The painting tool becomes unusable.

and 57073

However, it is valuable for a professional painting, except that the tile acts as an intermediate member with respect to the adjacent wall, that said tile can also provide a so-called saving edge, wherever desired, i.e., on behalf of the paint and a geometrically flat joint edge. The invention eliminates the disadvantages of hitherto known painting rollers such as those set out in the introduction, and the features of the invention will become apparent from the features of claim 1.

A preferred embodiment of the latter arrangement consists of a spring fixed to one end of the shaft, the other end of which is connected to a pin which is freely rotatable in an opening made in the plate. When the paint roller is used, the tile follows a rotational movement, i.e. a movement with respect to a fixed axis, whereby the spring ensures that the plate remains against the end surface of the roller.

The accompanying drawings show a suitable embodiment of a painting tool according to the invention, and the following description explains in more detail the example shown in the drawings.

Figure 1 shows a perspective view of a painting tool according to the invention.

Figure 2 is a longitudinal section of the painting tool of Figure 1.

In Figures 1 and 2, the number 10 denotes a tubular part which forms the core of the paint roller and which is provided with a suitable application material 11, for example lamb's wool or an artificial substance.

The core 10 has a bore at one end having a diameter larger than the diameter of the bore extending in the other direction and thus forming a space 12. The shaft 13 is insertable inside the bore and the roller 10,11 is freely rotatable with respect to this shaft. The shaft 13 continues as a handle part 14. The free end of the roller 10,11 is provided on the outside with a cylindrical plate 17 having a diameter at least equal to the diameter of the layer 11. In the embodiment shown in Figures 1 and 2, the plate 17 is provided with a bore in which a freely rotating pin 15 is arranged.

The free end of the pin 15 is releasably connected to the shaft 13 by means of a spring 16. When using a painting tool, the layer 11 is pressed against the substrate to be painted and at the same time the roll is usually moved over the substrate surface. Due to the attachment of the plate 17, this rotates with the roller 10,11 on the one hand, while the force exerted on the tool has the effect that the circumference of the plate 17 is always in the same plane as the layer 11 due to the space 12 and always moves it passes in front of the roller 10,11, as can be seen in Figure 1. This property is created by

Claims (2)

The radius of 3,57073 is constant, while the radius of the roller 10,11 when the material is pressed into contact with the substrate becomes smaller than the radius of the plate 17. The mobility of the slab thus ensures that the entire layer functions efficiently, while the slab acts as a saving edge and protects the substrate, which runs approximately perpendicular to the substrate to be painted, from painting. In both respects, the plate 17 acts as a guide for the possible parts of the layer 11 which protrude laterally. In principle, the plate 17 performs a circular movement, where the walls of the space 12 form a restraining response to the pin 15. It is obviously necessary that there must be a certain relationship between the attachment of the pin 15 or other plate 17 and the space 12. In the example shown, the holding has a diameter of 12, which is three times larger than the diameter of the pin 15. It can also be expressed in such a way that the elasticity of the layer 11 together with the maximum wear of the layer gives an indication of the appropriate radius of the cavity 12. Very „flat n.k. the saving edge is always achieved, regardless of the condition of the application surface. 1. Arrangement for painting tools, called rollers or painting rollers, having a tubular part, the outer surface of which is provided with a material suitable for applying paint and having a certain flexibility and absorbency, such as lamb's wool or artificial material, plus an axis around which the roller can rotate freely; is inserted into a tubular part, one end of the shaft acting directly or indirectly as a handle and the other end cooperating with a plate arranged outside the free end of the roller, characterized in that the plate (17) is round and has a substantially equal diameter than the diameter of the painting roller (11) and is provided with a shaft (15) arranged centrally in the plate, dimensioned with respect to the diameter of the opening in the tubular part so that said shaft (15) makes the geometric center of the roller (11) with respect to the concentric movement bounded by the interior of the roller aperture and then take with it a plate (17) which, only by spring tension (16), rests against the outer end of the roll. An arrangement according to claim 1, characterized in that the free end of the shaft (15) is connected to one end of a tension spring (16), the other end of which is connected to the end of the shaft part (13) inside the tubular part.
