The paint supply tube extends into a proximal portion of the brush channel. The brush hairs bounding the paint supply tube extend beyond the distal end of the paint supply tube and preferably with a length such that the brush hairs move towards each other under reduced pressure in the paint reservoir so that the outlet opening of the paint supply tube is substantially closed by the brush hairs. An adjustable guide element may be provided on the spout for stable positioning of the brush tip relative to the surface to be painted.

Description

Title: Paint tools and method for the purpose of circumcision

FIELD

The invention relates to a dyeing tool for cutting. Circumcision is understood to mean the operation by which a clean line of paint is applied at an internal angle which extends over a certain length and which forms the transition from two surfaces oriented at an angle with respect to each other. Hereafter, an internal connection angle will simply be referred to as the angle. The invention also relates to a method for cutting a paint line or line of paint at an internal angle and subsequently painting a surface limiting surface with the aid of a paint roller.

BACKGROUND

Cutting is widely used in, for example, the painting of frames where the angle is formed by a window and the frame in which the window is mounted. Often the window pane is fixed in the frame with the aid of a kit. When painting the window frame, a kit of paint should also be covered that extends to the window pane. A good watertight seal is thus formed, which protects the sealant against weather influences, so that a durable stable fixation of the window pane is obtained in the frame. However, cutting also takes place when painting panel doors or other objects provided with internal corners, such as paneling, furniture and the like. Professional painters often cut such corners out of hand, which requires a stable hand and must be performed with the necessary care. Hand-cutting requires professional skill and is time-consuming. Instead of hand-cutting, masking tape is also used. However, applying masking tape is also a time-consuming job.

In WO2011 / 155843 A1, the present applicants have described a painting tool for cutting. Although this paint tool is quite satisfactory, the development has continued and further problems have been solved. SUMMARY OF THE INVENTION According to a first aspect of the invention, a painting tool for cutting is provided which comprises: a paint reservoir; - a brush provided with brush hairs which together define a brush surface which extends substantially concentrically around a brush axis in a non-loaded state and which extends from a proximal end with a substantially circular cross-section to a distal end forming a sharp brush tip, the brush surface from the proximal end to the distal end has a substantially conical tapered configuration; - a paint supply tube extending along a paint supply tube center line, wherein the paint supply tube center line extends parallel to the brush axis, the paint supply tube being provided with an inlet opening at a proximal end and an outlet opening at a distal end, the inlet opening being in fluid communication with the paint reservoir; a spout provided with a supply channel defining a supply axis, wherein in a distal end of the supply channel the brush is attached with the proximal end, wherein the proximal end of the paint supply tube opens into the supply channel at a point proximal to the proximal end of the brush; - a brush channel formed in the brush and bounded by brush hairs, wherein a brush channel axis of the brush channel extends parallel to the brush axis and a distal end of which opens into the brush surface, the paint supply tube extending into a proximal part of the brush channel and wherein the brush channel further extends distally from the distal end of the paint supply tube by the brush hairs delimiting the brush channel extending beyond the distal end of the paint supply tube.

Due to the presence of the brush channel which debouches in the field surface, the paint supplied via the paint supply tube is supplied directly, i.e. with relatively low flow resistance, to the brush surface. The brush channel center line and the paint supply line center line coincide with each other but are staggered relative to the brush center line. As a result, the brush actually has a brush tip. The presence of this brush tip is essential to crop a nice clean line of paint. Because the brush channel is arranged staggered relative to the brush axis, the paint transported to the brush surface during cutting by the brush hairs which extend downstream of the opening in the brush surface is directly evenly distributed on the surface, while with the aid of the brush tip distributed paint can be accurately controlled so that a tight line of paint or paint line can be obtained. It is therefore possible to cut even more accurately with the aid of the paint tool according to the invention than with the known paint tool.

In one embodiment, the brush hairs bounding the paint supply tube extend beyond the distal end of the paint supply tube with such a length that the brush hairs move towards each other under reduced pressure in the paint reservoir so that the outlet opening of the paint supply tube is substantially closed by the brush hairs. In general, the paint reservoir and will be designed as a tube. When the tube is squeezed, paint is supplied to the paint supply tube and cutting can take place. As soon as the squeezing force is released on the tube, an underpressure is created in the paint supply tube, as a result of which there is also an underpressure in the brush channel in the brush. As a result, the hairs which border the brush channel and which extend beyond the distal end of the paint supply tube move towards each other and thereby substantially close the outlet of the paint supply tube. As a result, no drops of paint fall on the ground or on other parts, such as parts that have already been painted.

Another problem for which the inventors found themselves is the fact that not every angle is the same. Sometimes one of the two limits the surfaces to be particularly low, so that there is hardly any room to support against them with the spout. In some cases, there is a particularly small amount of sealant in the corner, while in other cases a particularly large amount of sealant is provided in the corner.

In a further embodiment, the painting tool is provided with a guide element provided with a substantially tubular wall defining a central passage, the guide element being adjustably mounted on the spout because the spout is located in the central passage of the guide element wherein a distal edge of the tubular wall of the guide member defines at least one guide point that can be pressed against a guide surface in use of the painting tool, wherein by adjusting the guide member on the spout the position of the at least one guide point can be set in relation to the position of the brush point.

As a result of the presence of the adjustable guide element, the at least one guide element can be positioned relative to the brush tip, so that corners with different depths, for example as a result of a differently applied kit, can be cut. Angles at which the two bounding surfaces are not perpendicular to each other can also be excellently cut with such an adjustable guide element.

The invention also provides a method which comprises: applying a paint line at an internal angle between two surfaces by cutting with the aid of the painting tool according to the invention; and covering at least one of the surfaces bounding the internal angle with the aid of a paint roller.

With the aid of such a method, corners can be cut very quickly and accurately and one or both of the surfaces that limit the angle can be painted with the paint roller. In practice it appears that a work that mainly consists of painting window frames can be carried out two to five times faster than with the help of conventional paint methods, while the end result is even tighter and technically better than can be achieved with the conventional paint methods.

Further elaboration of the invention are described in the subclaims and will be further clarified below with reference to the figures.

DETAILED DESCRIPTION

In the most general terms, the invention provides a dyeing tool 10 for cutting purposes. As is clearly visible in the example shown in the figures, more particularly in figures 1-4, the paint tool comprises a paint reservoir 12 and a brush 14 provided with brush hairs which together define a brush surface. In the unloaded state, the brush surface extends substantially concentrically about a brush axis 14L. Here, the brush surface extends from a proximal end 14p with a substantially circular cross-section to a distal end 14d that forms a sharp brush tip. The brush surface has a substantially tapered configuration from the proximal end 14p to the distal end 14d. Furthermore, the paint tool 10 is provided with a paint supply tube 16 that extends along a paint supply tube center line 16L, the paint supply tube center line 16L extending parallel to the brush axis 14L of the brush. The paint supply tube 16 is provided with an inlet opening 16i at a proximal end 16p and an outlet opening 16o at a distal end 16d. The inlet opening 16i is in fluid communication with the paint reservoir 12. The paint tool 10 also has a spout 20 provided with a supply channel 22 which defines a supply channel axis 22L. In a distal end 22d of the supply channel 22, the brush 14 with the proximal end 14p is attached thereto. The proximal end 16p of the paint supply tube 16 opens into the supply channel 22 at a point proximal to the proximal end 14p of the brush 14. Thus, the paint can be supplied directly from the supply channel 22 of the spout 20 to the paint supply tube 16. The proximal end 14p of the brush 14 is not in direct fluid communication with the paint in the supply channel 22. Therefore, paint is supplied to the brush 14 only through the paint supply tube 16. A brush channel 18 is formed in the brush 14 and bounded by brush hairs. A brush channel axis 18L of the brush channel 18 extends parallel to the brush axis 14L. A distal end 18d of the brush channel 18 opens into the brush surface. The paint supply tube 16 extends into a proximal part of the paint channel 18 and the paint channel 18 further extends distally from the distal end 16d of the paint supply tube 16 in that the brush hairs that border the paint duct 18 extend beyond the distal end 16d of the paint supply tube 16 extend.

In an embodiment, an example of which is shown in the figures, the brush hairs bounding the paint supply tube 16 can extend beyond the distal end 16d of the paint supply tube 16 with such a length that the brush hairs move towards each other under reduced pressure in the paint reservoir 12 so that the outlet opening of the paint supply tube 16 is substantially closed by the brush hairs.

In an embodiment, two examples of which are shown in the figures, the painting tool 10 may further be provided with a guide element 24 which has a substantially tubular wall 26 which defines a central passage 28. Details of the two guide elements 24 are shown in Figures 6-14. The guide element 24 can be mounted adjustable on the spout 20 in that the spout 20 extends into the central passage 28 of the guide element 24. In this embodiment, a distal edge 26d of the tubular wall 26 of the guide element 24 forms at least one guide point 30, 32, 34 which can be pressed against a guide surface in the use of the painting tool. The guiding surface is generally formed by one or both of the surfaces that limit the angle. A stable positioning of the brush tip relative to the angle can thus be obtained. In this embodiment, by adjusting the guide element 24 on the spout 20, the position of the at least one guide point 30, 32, 34 can be adjusted relative to the position of the brush tip.

The advantages of the invention and the two embodiments thereof described above have already been discussed above in the summary of the invention to which reference is now made.

Although in the example shown the guide element 24 is provided with three guide points 30, 32, 34, in an alternative embodiment the distal edge 26d of the tubular wall 26 can also have only two guide points or even only one guide point. A distal edge 26d with more than three guide points 30, 32, 34 also falls within the scope of this embodiment. A distal edge 26d with three guide points 30, 32, 34 has the advantage that three guide points form a three-point support and thus provide stable positioning on a surface or at an angle between two surfaces.

In an embodiment, an example of which is shown in the figures, more particularly figures 5-7, the distal edge 26d of the tubular wall 26 of the guide element 24 may form three guide points 30, 32, 34 located at a circle C whose center point M is located on the brush center line 14L. Viewed in the direction of the transit axis 28L from a distal end 24d of the guide member 24 to a proximal end 24d of the guide member 24 (see Figure 11), the three guide points 30, 32, 34 can thereby be located on an equilateral triangle. A first and a second guide point 30, 32 in this embodiment are located at two base angle points B1, B2 which form the end points of a base B of the equilateral triangle. A third guide point 34 is located at a top angular point T of the equilateral triangle opposite the base. A perpendicular perpendicular ML of the equilateral triangle extends from the apex vertex T to the base B of the triangle. The center M of said circle C lies on the center perpendicular ML. In this embodiment, the brush channel axis 18L of the brush channel in the brush 14 and the coinciding paint supply tube axis 16L intersect the center perpendicular ML at a point S which is located between the apex point T and the center M of the circle.

With a guide element 24 designed in this way, a stable three-point support is obtained with which also a correct positioning of the paint supply tube 16 relative to the surface to be painted, i.e. a positioning of the paint supply tube 16 during use on the convex curved side of the brush 14 Thus, the chance that a painter positions the painting tool 10 in the wrong way relative to the surface to be painted is minimized and a tightly cut line of paints 86 can be formed very quickly.

Instead of or in addition to one or more guide points 30, 32, 34, the distal edge 26d can also form guide surfaces with the aid of which the guide element 24 can be supported on one or both of the surfaces which limit the object to be painted. For example, in one embodiment, the distal edge 26d may comprise two distal edge portions 26d1, 26d2, wherein a first distal edge portion 26d1 extends in a first plane 26V1 and wherein a second distal edge portion 26d2 extends in a second plane 26V2. The two faces 26V1, 26V2 can herein enclose an angle α of approximately 90 ° with each other. In the example shown in the figures, the distal edge 26 is indeed so designed and the third guide point 34 lies substantially on the intersection of the two planes, while the first guide point 30 is substantially in the first plane 26V1 and the second guide point 32 is located. substantially in the second plane 26V2. Tests have shown that a guide element 24 designed in this way provides excellent support and stability for creating a particularly tight cut line 86 in a very short time. The guide points 30, 32, 34 do not lie precisely in the said planes 26V1 and 26V2 because the distal edge part 26d is slightly rounded at the location of the guide points 30, 32, 34.

In an embodiment, an example of which is shown in the figures, the tubular wall 26 of the guide element 24 may be interrupted by a recess 36 which extends the entire length of the tubular wall 26 and is substantially parallel to a center line 28L of the central passage 28.

The recess 36 can first of all provide space for receiving brush hairs located on the concave side of the brush 14. As a result, it can be prevented that the brush tip would be flattened during bending or flexing and no longer has a true point shape. Loss of the pure point shape adversely affects the tightness of the circumcised line. Hence, a receiving space formed by the recess 36 is advantageous. A second effect of the recess 36 is that the tubular wall 26 becomes somewhat flexible, so that the inside diameter of the tubular wall 26 can be slightly increased by moving the edges of the tubular wall 26 away from each other which bound the recess 36. Increasing the inner diameter of the tube wall 26 can be advantageous when moving the guide element 24 on the spout 20.

In an embodiment, an example of which is shown in the figures, the tubular wall 26 of the guide element 24 may be provided with a circumferential groove 38, wherein a first O-ring 40 is received under pretension in the circumferential groove 38, so that recess 36 Slightly compressed and in the mounted state of the guide element 24 on the spout 20 there is a friction-based connection between the guide element 24 and the spout 20.

The O-ring 40 can exert a permanent tensioning force, so that even after prolonged use, the guide element 24 is still firmly clamped on the spout 20. Without O-ring 40, as a result of stress relaxation in the plastic of the guide element 24, the tension force of the guide element 24 on the spout 20 could gradually decrease so that the frictional resistance between the guide element 24 and the spout 20 would be too far can be reduced to ensure stable positioning of the guide element 24 on the spout 20. With the aid of the O-ring 40, the occurrence of this undesired phenomenon can be prevented.

In an embodiment, an example of which is shown in Figures 12-14, engaging means 42 can be connected to the tubular wall 26 which can be engaged by hand. Such engaging means 42 can be configured to manually flex the tubular wall 26 when engaged, so that the inner diameter of the guide member 24 is increased. As a result, the frictional force between the guide element 24 and the spout 20 is reduced, so that the adjustment of the guide element 24 relative to the spout 20 and hence relative to the brush tip can take place with less force and therefore more accurately. It is also possible to use the engaging means with a guide element 24 which is not provided with an O-ring for creating the pinching force. The guiding element 24 may, for example, have a slightly smaller inner diameter than the outer diameter of the spout 20 in the relaxed state, so that internal stresses in the guiding element already create sufficient squeezing force and hence sufficient frictional force for a stable attachment of the guiding element 24 on the spout 20. The gripping means 42 may, for example, be designed as a type of pincher provided with two levers which are connected to the tubular wall 26 and which can be squeezed towards each other between thumb and forefinger, so that the inner diameter of the tubular wall 26 is slightly increased and accurate displacement of the guide element 24 on the spout 20 is possible.

In an embodiment, an example of which is shown in the figures, a cam 44 may be provided on the spout 20 which is received in the recess 36 in the tubular wall 26 of the guide element 24. The mutual engagement between the cam 44 and the recess 36 provides a rotational orientation of the guide element 24 relative to the spout 20.

In an embodiment, an example of which is shown in the figures, the paint tool 10 may be provided with a clamping sleeve 46 in which the proximal end of the brush 14 and the paint supply tube 16 are clamped. The clamping sleeve 46 can herein be provided on an outer surface thereof with an orientation cam 48, the rotational position of the paint supply tube 16 and the orientation cam 48 being fixed relative to each other. The supply channel 22 of the spout 20 can be provided with an orientation recess 50 for receiving the orientation cam 48, such that the rotational position of the clamping sleeve 46 and thus of the paint supply tube 16 relative to the spout 20 is fixed.

In a combination of the latter two embodiments, an example of which is shown in the figures, the rotational position of the orientation recess 50 lies in the supply channel 22 of the spout 20 and the rotational position of the cam 44 on the spout relative to each other. As a result, the rotational position of the paint supply tube 16 relative to the rotational position of the guide element 24 is also fixed.

This is of great importance because during cutting the brush 14 is always bent in a bend which is convex on the side of the brush 14 facing the surface to be painted and on the side of the brush 14 facing away from the surface to be painted . By fixing the rotational position of the paint supply tube 16 relative to the guide element 24 and hence relative to the at least one guide point 30, 32, 34, it can be guaranteed that the paint supply tube 16 is always closer to the convex side of the brush 14 is then at the concave side of the brush 14. As a result, the paint will always reach the brush surface on the convex side of the brush 14, i.e. on the side of the brush 14 facing the surface to be painted. The brush hairs extending downstream of the mouth of the brush channel 18 into the brush surface together form the brush tip and the paint is therefore immediately nicely distributed immediately after delivery through the said brush channel mouth into the brush surface to form a line while using the brush tip the line boundary can be controlled very accurately. This steering can take place so precisely because the at least one guide point 30, 32, 34 of the guide element 24 can be pressed against one of the surfaces that limits the angle. Preferably, support is thereby provided against the two surfaces that limit the angle. As a result of this configuration, it is ensured that sufficient paint is always available to form the tight line of paint 86 and, as a result of the accurate positioning of the brush channel mouth with respect to the surface to be painted, a good distribution of the paint is achieved by means of the brush 14.

In an embodiment, an example of which is shown in the figures, the painting tool 10 may be provided with a coupling piece 52 which is connected to the paint container 12 with a proximal coupling piece end 52p and which is connected to a distal coupling piece end 52d with a proximal end 20p of the spout 20. The paint reservoir 12 may be designed as a tube, the tube being provided with a tube wall 54 and a tube mouth 56. In such an embodiment, the tube mouth 56 forms a distal mouth edge 56a that extends in a mouth rim surface 56P. The tube wall 54 defines a tube axis 54L that extends perpendicular to the mouth edge surface and intersects an imaginary center of the mouth edge. According to the present embodiment, the connector 52 is curved so that when the tube 12 is connected to the proximal connector end 52p and the spout 20 is connected to the distal connector end 52d, the tube center line 54L and the supply channel centerline 22L embed corner φ.

This kinked coupling piece 52 simplifies the use of the painting tool 10 in that it is also easier to cut above the head in a corner with the painting tool 10. After all, the tube can be held in a downwardly facing position, while the spout 20 can be positioned in a suitable angular position relative to the surface to be painted (see figure 15).

With a painting tool as known for example from WO2011 / 155843 A1, the center line of the tube and the center line of the spout were co-axial, with the result that a staircase around the spout had to be used fairly quickly in a correct angular position with respect to to be able to position the surface to be painted.

In a further elaboration, the angle φ is preferably in the range of 30 - 60 °, and more particularly the angle bedraagt is approximately 45 °.

When the paint container 12 is empty, it must be possible to fill it quickly. To this end, in one embodiment the connection between the spout 20 and the coupling piece 52 can be a bayonet connection. Such a bayonet makes it possible to quickly disconnect the spout 20 from the coupling piece 52. A fairly large opening is hereby formed through which the tube can be filled quite easily with paint.

In an embodiment in which the guide element 24 is designed as described in claim 4 and therefore has three guide points 30, 32, 34 which are located at the corner points of an imaginary equilateral triangle, it can be of particular advantage if the bayonet connection is configured to allow different positions of the spout 20 relative to the coupling piece 52. In such an embodiment, in a first position of the spout 20 on the coupling piece 52, the said central perpendicular ML can be situated in the same plane as in which the tube center line 54L and the supply channel center line 22L of the spout 20 extend. In a second position of the spout 20 on the coupling piece 52, the said center perpendicular ML can extend perpendicularly to the plane in which the tube center line 54L and the supply channel center line 22L extend.

In an embodiment, an example of which is shown in the figures, the connection between the tube 12 and the coupling piece 52 can be a screw connection. Tubes provided with a mouthpiece with external thread are generally known. The present tube 12 differs from the known tubes in that the inner diameter of the nozzle is relatively large, so that the tube 12 can be filled with paint via the tube mouth 56 and air can escape from the tube during filling. Relatively large in this context is to be understood to mean an inner diameter in the range of approximately 10-40 mm.

In order to form a fluid-tight connection between the tube 12 and the coupling piece 52, the painting tool 10 may be provided with a second O-ring 58 which is included in the connection between the coupling piece 52 and the tube 12.

In order to form a fluid-tight connection between the coupling piece 52 and the spout 20, the painting tool 10 can be provided with a third O-ring 60 which is included in the connection between the coupling piece 52 and the spout 20.

In order to limit the drying out of brush 14 during use of the painting tool 10 in breaks as much as possible, in one embodiment the painting tool 10 can be provided with a cap 62 which can be placed on the spout 20 and forms a substantially airtight shield of the brush 14 relative to the environment.

In an embodiment, an example of which is shown in the figures, the coupling piece 52 may be provided with at least one flat supporting surface 52a which is positioned such that when the paint tool 10 with the supporting surface 52a lies on a horizontal surface, the brush 14, viewed from the proximal brush end 14p to the distal brush end 14d, is tilted up. When the paint tool 10 with the support surface 52a is placed on a horizontal surface, the brush 14 and the spout 20 are inclined upwards, which ensures that no paint drips from the brush 14 in that rest position when the paint tool is not used. The example of the painting tool 10 shown in the figures is provided with two such supporting surfaces 52a which are visible in Figure 15.

Figures 15 and 16 show the use of the painting tool 10 during the cutting of an angle 80 between two surfaces 82, 84. It is clearly visible that one, two or all three of the guide points 30, 32, 34 against one or both of the two surfaces 82, 84. In particular, Figure 16 shows that the brush 14 is slightly bent because it is pressed against one or both surfaces 82, 84. With the aid of the painting tool 10 a very tight line of paint 86 can be cut in a particularly fast manner, that is to say much faster than with the aid of masking tape or cutting by hand.

After applying the paint line 86 which has been cut with the painting tool, a surface of paint can be provided, for example, quickly and efficiently with a paint roller 100 with stop 120. The paint roller 100 is preferably designed in the manner described in the patent application filed simultaneously by the applicant (s) which relates to a paint roller 100 provided with a handle 126 which is fixedly rotatably connected to the paint roller shaft 106. The content of that application is inserted here as considered.

The invention also provides a method which comprises: applying a paint line 86 at an internal angle 80 between two surfaces 82, 84 by cutting through using the painting tool 10 according to the invention; and covering at least one of the surfaces bounding the internal corner 80 by means of a paint roller 100 with stop 120.

With the aid of such a method, which is shown in figures 15-17, corners 80 can be cut very quickly and accurately and one or both of the surfaces 82, 84 bounding the corner 80 can be painted. In practice it appears that a work that mainly consists of painting window frames can be carried out two to five times faster than with the aid of conventional paint methods, while the end result is even tighter and technically better than can be realized with the conventional paint methods.

In a further elaboration of the method in which the paint roller 100 is provided with a handle 126 connected rotationally to the paint roller shell 106, the method can also comprise that the stop 120 is adjusted by rotation in the axial direction with respect to the paint roller shell 106 while the The paint roller 100 is held by the painter on the handle 126. Thus, without the painter getting dirty hands, the stop 120 can be correctly positioned, so that when painting the surface 82 and / or 84 the side edge of the cut paint line 86 becomes neat. covered by the paint applied with the paint roller 100.

It will be clear that the method may also include adjusting the guide element 24 with respect to the spout 20 and thus with respect to the brush tip 14d. It can thus be realized that during the application of the method the width and position of the cut line of paint 86 can be accurately matched to the details of the relevant corner 80, such as, for example, the design of the kit arranged in the corner 80 or angle between both surfaces 82, 84.

Although the above-described embodiments have all been used in the example shown in the figures, it is important to understand that the embodiments described above can be used independently of each other in other examples of the painting tool. Reference numerals used in the detailed description are merely for the purpose of clarification and do not limit the description. The detailed description can also be read without reference numerals and therefore also forms a description of the various embodiments without relation to the example in the figures.
