Description

PAINT OR VARNISH FEEDER AND PAINTING DEVICE COMPRISING SAID FEEDER
DESCRIPTION
The present invention refers to the field of roller devices for applying paint or varnish to a surface, particularly but not exclusively for painting walls both vertical and horizontal (floors or ceilings).
It is known to use - for example, to whitewash a wall - a roller which is used by dipping it into a recipient containing the paint, then by eliminating the excess paint with various expedients and finally by passing the roller over the wall several times until the paint it carries is used up, after which the roller is dipped again into the recipient.
The system used leaves much space for personal skill and experience, which means that a beginner will easily obtain poor or uneven results.
Furthermore, the amount of paint or of varnish distributed on each stroke of the roller is not even but it gradually decreases from the first stroke to the last one before the roller is dipped again into the recipient.
In addition, the movements necessary to supply again the roller with paint lead to a waste of energy and of time.
To overcome these drawbacks there are known and available on the market painting devices comprising so-called "feeders" which, connected to a tank containing the paint or the varnish and placed in contact with the roller, pick up from the tank and supply to the roller the amount of paint or of varnish necessary each time, eliminating (or at least drastically reducing) the waste and/or the risk that part of the paint or of the varnish may leak from the painting device dripping onto the user, the walls and/or the ground.
Operation of a feeder will not be described here because it is per se known.
It has nevertheless been noted that, at least in certain conditions of use (for example when painting a ceiling), the already known feeders are not able to avoid the paint for dripping - or being able to drip - on the operator and/or on the ground. Object of the present invention is a feeder for a roller-painting device suitable to avoid this risk.
A feeder according to the present invention is disclosed in independent claim 1; further characteristics of said feeder are disclosed in the dependent claims.
The present invention further refers to a painting device provided with a feeder (or applicator) made according to the present invention.
The invention achieves the above object, in particular it allows a controlled delivery of paint or of varnish onto the roller of the painting device without the need to perform tiring and time-consuming movements; furthermore, it has been seen experimentally that it allows more even results to be achieved than those that can be achieved with traditional painting.
Exemplary embodiments of the invention will be described below purely by way of non- limiting examples and with reference to the appended drawings, in which:
- Figure 1 shows diagrammatically a side view of a roller-painting device - per se known. — comprising a feeder made according to the invention;
- Figure 2 shows diagrammatically a front view of the painting device of Figure 1;
- Figure 3 shows an axonometric view of an embodiment of the feeder of Figure 1;
- Figure 4 shows a side view of the feeder of Figure 3 sectioned along the plane IV-IV of Figure 3; - Figure 5 shows a side view of a further embodiment of the feeder of Figure 3 sectioned along the plane W-IV of Figure 3;
- Figure 6 shows diagrammatically an enlarged view of a part of the roller-painting device of Figure 1;
- Figure 7 shows an axonometric view of a further embodiment of the feeder of Figure 1. In the appended figures corresponding elements shall be identified by the same reference numerals.
Figures 1 and 2, respectively, show a side view and a front view of a roller-painting device indicated as a whole with reference numeral 1 and comprising a feeder 2 made according to the invention. The painting device 1 comprises a handle 3 which carries a roller-type head 4 consisting of a roller 5 of conventional type (able to rotate on a supporting frame 6 integral with the handle 3) and of the feeder 2, which comprises at least one hollow manifold 7 (Figure 4) comprising one or more chambers and a hollow surface 12 made in the feeder flat face 14 destined to come into contact with the roller 5 and which is connected to the paint or varnish tank by flexible supply hoses 9.
The hollow surface 12 is shaped like an arc of a circle and along its longitudinal axis there is at least one groove 13 directly connected to the at least one manifold 7.
Figure 7 shows a feeder 2 providing a hollow surface 12 where two grooves 13 parallel to each other and to the longitudinal axis of the hollow surface 12 and directly connected to the at least one manifold 7.
The at least one manifold 7 receives the paint or the varnish from the flexible supply hoses 9 and delivers it to the roller 5 through the at least one longitudinal groove 13.
If compared to the at least one group of delivery openings which supplies to the roller 5 the paint or the varnish in the already known feeders, the at least one longitudinal groove 13 of a feeder 2 realised according to invention allows a more uniform supplying of the paint or of the varnish to the roller 5, improving the performances of the painting device 1.
Furthermore, the at least one longitudinal groove 13 is less subject to be clogged and is easier to be cleaned than the delivery openings provided by the already known feeders.
In the painting device shown in Figures 1 and 2, the at least one chamber of the manifold 7 receives the paint or the varnish through a distributor 10 and the feeder 2 is carried by means 11 able to bring it into contact with the roller 5 (respectively away from the roller 5) only on user's command; the distributor 10 and the means 11 will not be described herein because they are per se known and in any case outside the scope of the present invention.
Advantageously, the means 11 includes stop means 15, controlled by the user, to avoid that the hollow surface 12 of the feeder 2 (Figure 3) be pressed against the roller 5 preventing (or at least interfering with) the rotation of the roller 5 on the support frame 6. Figure 3 is an axonometric view of an embodiment of the feeder 2 of Figure 1, which has on the flat face 14 destined to come into contact with the roller 5 the hollow surface 12, shaped like an arc of a circle, along the axis of which a longitudinal groove 13, directly connected to the at least one manifold 7, is present.
The flat face 14 previously bends the bristles of the roll 5, thus eliminating the risk of unwanted leakage of the varnish or of the paint.
The hollow surface 12 allows the feeder 2 to "embrace" the roller 5 better than the feeders of the prior art, thus eliminating the risk of unwanted leakage of the varnish or of the paint.
In order to confer a greater elasticity of use on a feeder 2 made according to the invention, the hollow surface 12 advantageously has a radius not smaller than that of the largest sized roller 5 with which the feeder 2 is destined to come into contact.
The width of the at least one longitudinal groove 13 is preferably about 0.6 mm and in any case comprised between about 0.5 mm and about 2 mm whilst its depth is about 3 mm and in any case comprised between about 0.5 mm and about 3.5 mm.
Figure 4 is a side view of the feeder 2 of Figure 1 sectioned along the plane IV-IV of Figure 3: in Figure 4 the manifold 7, the hollow surface 12 and the paint or varnish distributing longitudinal groove 13 can be seen, the longitudinal groove 13 being directly connected to the manifold 7 without interposing perforated plates or the like.
Without departing from the scope of the invention, the at least one longitudinal groove 13 can be trapezoidal in section; the width of the major base is preferably about 2 mm and in any case comprised between about 1 mm and about 4 mm, the width of the minor base is preferably about 0.7 mm and in any case comprised between about 0.6 mm and about 1 mm.
Preferably, the major base of the at least one longitudinal groove 13 is positioned near the at least one manifold 7.
Always without departing from the scope of the invention, two or more feeders 2 supplied with different paints or varnishes can be applied to the same roller 5.
The present invention further includes a painting device 1, like that illustrated in Figures 1 and 2, comprising a feeder 2 made according to the present invention.
Other possible variants with respect to what is described may occur to a person skilled in the art; however, said variants accessible to a person skilled in the art are understood as included in the scope of the invention as defined in the appended claims.
