Definitions

  • the invention relates to a painting tool for cutting in.
  • Cutting-in is understood to mean the act by which a sharp line of paint is applied in an internal corner which extends over a certain length and which forms the transition of two surfaces oriented at an angle to each other. In the following, such a connective internal corner will also be simply referred to as corner.
  • the invention further relates to a method for cutting-in a paint line or paint stripe in an internal corner and then painting a surface bounding the corner using a paint roller.
  • Cutting-in is widely used for the purpose of painting of, for example, window frames where the corner is formed by a pane and the frame in which the pane is fastened. Often, the pane is secured in the frame with the aid of sealant. When painting the frame, sealant should also be covered with a layer of paint that extends up to the pane. Thus a good watertight seal is formed, protecting the sealant from weather influences so that a durable, stable fastening of the pane in the frame is obtained.
  • cutting-in is also done when painting, for example, panel doors or other internally cornered objects, such as wainscoting, furniture and the like. Professional painters often cut-in such corners freehand, which requires a steady hand and should be done with the necessary accuracy. Freehand cutting-in requires skill and is time-consuming. Also, instead of freehand cutting-in, use is made of masking tape. However, applying masking tape is also a time consuming job.
  • DE202006000637U1 discloses a paint cartridge with a spout including a brush which is mounted in and extends from a cylindrical nozzle.
  • a paint supply tube extends into the brush.
  • Mounted on the nozzle is a guiding tube which is axially movably arranged on the nozzle.
  • On the guiding tube a cover sleeve is mounted or integrally formed therewith.
  • the cover sleeve has a distal opening which engages the brush hairs to force the brush hairs into a desired shape, e.g. a circular shape or a flattened shape.
  • a painting tool for the purpose of cutting-in according to claim 1.
  • the paint supplied via the paint supply tube is directly, that is, with relatively low flow resistance, passed to the brush surface.
  • the brush channel axis and the paint supply tube axis coincide with each other but are staggered with respect to the brush axis.
  • the brush in actual fact has a pointed brush tip.
  • the presence of this pointed brush tip is of essential importance to cut-in a fine sharp paint line.
  • the paint transported toward the brush surface during cutting-in is directly uniformly distributed on the surface by the brush hairs extending downstream of the opening in the brush surface, while with the aid of the brush tip, the boundary of the distributed paint can be accurately controlled so that a sharp straight paint stripe or paint line can be obtained.
  • cutting-in can therefore be still more accurate than with the known painting tool.
  • the brush hairs bounding the paint supply tube extend beyond the distal end of the paint supply tube by such a length that the brush hairs at a reduced pressure in the paint reservoir move towards each other so that the outlet opening of the paint supply tube is substantially closed off by the brush hairs.
  • the paint reservoir will be implemented as a tube. When the tube is squeezed, paint is supplied to the paint supply tube and cutting-in can be done. As soon as the squeezing force on the tube is released, a reduced pressure arises in the paint supply tube as a result of which a reduced pressure also arises in the brush channel in the brush.
  • the painting tool includes a guiding element provided with a substantially tubular wall defining a central passage, the guiding element being adjustably mounted on the nozzle in that the nozzle extends in the central passage of the guiding element, wherein a distal edge of the tubular wall of the guiding element defines three guiding points which, in use of the painting tool, can be pressed against a guiding surface, whereby through adjustment of the guiding element on the nozzle, the position of the guiding points can be set with respect to the position of the brush tip, wherein the three guiding points are substantially located on a circle whose center is located on the brush axis, and wherein, viewed in the direction of the brush axis from a distal end of the guiding element to a proximal end of the guiding element, the three guiding points are substantially located on an equilateral triangle, a first and a second guiding point being substantially located on two base angular points forming the end points of a base of the equilateral triangle, and a third guiding
  • the at least one guiding element can be positioned with respect to the brush tip, so that corners of different depths as a result of, for instance, sealant applied in different manners, can be cut-in. Also corners where the two bounding surfaces are not at right angles to each other can be excellently cut-in with such an adjustable guiding element.
  • the invention also provides a method which comprises:
  • the invention provides a painting tool 10 for the purpose of cutting-in.
  • the painting tool comprises a paint reservoir 12 and a brush 14 provided with brush hairs jointly defining a brush surface.
  • the brush surface In non-loaded condition, the brush surface extends substantially concentrically around a brush axis 14L.
  • the brush surface extends from a proximal end 14p having a substantially circular cross section to a distal end 14d forming a pointed brush tip. From the proximal end 14p to the distal end 14d, the brush surface has a substantially conically tapering configuration.
  • the painting tool 10 further comprises a paint supply tube 16 extending along a paint supply tube axis 16L, with the paint supply tube axis 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 painting tool 10 also has a nozzle 20 provided with a supply channel 22 defining a supply channel axis 22L. In a distal end 22d of the supply channel 22, the brush 14 is fastened thereto by its proximal end 14p.
  • the proximal end 16p of the paint supply tube 16 terminates in the supply channel 22 at a point proximal with respect to the proximal end 14p of the brush 14.
  • the proximal end 14p of the brush 14 is not in direct fluid communication with the paint in the supply channel 22.
  • the brush 14 is therefore supplied with paint only via the paint supply tube 16.
  • a brush channel 18 is formed which is 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 terminates in the brush surface.
  • the paint supply tube 16 extends in a proximal part of the brush channel 18 and the brush channel 18 extends further distally of the distal end 16d of the paint supply tube 16 in that the brush hairs bounding the brush channel 18 extend beyond the distal end 16d of the paint supply tube 16.
  • the brush hairs that bound the paint supply tube 16 can extend beyond the distal end 16d of the paint supply tube 16 by such a length that the brush hairs at a reduced pressure in the paint reservoir 12 move towards each other so that the outlet opening of the paint supply tube 16 is substantially closed off by the brush hairs.
  • the painting tool 10 is further provided with a guiding element 24 having a substantially tubular wall 26 defining a central passage 28. Details of the two guiding elements 24 are shown in Figs. 6-14 .
  • the guiding element 24 is adjustably mounted on the nozzle 20 in that the nozzle 20 extends in the central passage 28 of the guiding element 24.
  • a distal edge 26d of the tubular wall 26 of the guiding element 24 in this embodiment forms three guiding points 30, 32, 34 which in use of the painting tool can be pressed against a guiding surface.
  • the guiding surface is generally formed by either or both of the surfaces bounding the corner. Thus, a stable positioning of the brush tip with respect to the corner can be obtained.
  • the position of the at least one guiding point 30, 32, 34 can be set with respect to the position of the brush tip.
  • a distal edge 26d with more than three guiding points 30, 32, 34 also falls within the framework of the invention.
  • a distal edge 26d with three guiding points 30, 32, 34 has the advantage that three guiding points constitute a three-point support and hence provide a stable positioning on a surface or in a corner between two surfaces.
  • the distal edge 26d of the tubular wall 26 of the guiding element 24 forms three guiding points 30, 32, 34 which are located on a circle C, the center M of which is located on the brush axis 14L.
  • the three guiding points 30, 32, 34 are located on an equilateral triangle.
  • a first and a second guiding point 30, 32 are located on two base angular points B1, B2 forming the end points of a base B of the equilateral triangle.
  • a third guiding point 34 is located at an apical angular point T of the equilateral triangle, located opposite to the base.
  • a perpendicular biscector ML of the equilateral triangle extends from the apical angular point T to the base B of the triangle.
  • the center M of the circle C mentioned is on the central perpendicular bisector ML.
  • the brush channel axis 18L of the brush channel in the brush 14 and the paint supply tube axis 16L coinciding therewith intersect the perpendicular bisector ML in a point S located between the apical angular point T and the center M of the circle.
  • the distal edge 26d can also form guiding surfaces with the aid of which the guiding element 24 can be supported on either or both of the surfaces bounding the corner of the object to be painted.
  • the distal edge 26d can comprise two distal edge parts 26d1, 26d2, with a first distal edge part 26d1 extending in a first plane 26V1 and with a second distal edge part 26d2 extending in a second plane 26V2.
  • the two planes 26V1, 26V2 can mutually include an angle ⁇ of approximately 90°.
  • the distal edge 26 is indeed of such a design and the third guiding point 34 is substantially on the line of intersection of the two planes while the first guiding point 30 is substantially in the first plane 26V1 and the second guiding point 32 is substantially in the second plane 26V2.
  • Tests have shown that a thus designed guiding element 24 provides excellent support and stability for creating a particularly straight sharp cut-in paint line 86 in a very short time.
  • the guiding points 30, 32, 34 do not lie exactly in the planes 26V1 and 26V1 as a result of the distal edge part 26d being slightly rounded off at the location of the guiding points 30, 32, 34.
  • the tubular wall 26 of the guiding element 24 may be interrupted by a recess 36 which extends throughout the length of the tubular wall 26 and is substantially parallel to a axis 28L of the central passage 28.
  • the recess 36 can provide space for receiving brush hairs located on the concave side of the brush 14. What can be prevented by this is that the brush tip would be pressed flat during bending or flexing and no longer have a truly pointed shape. Loss of the truly pointed shape has an adverse effect on the preciseness of the cut-in line. Hence, a receiving space formed by the recess 36 is of benefit.
  • a second effect of the recess 36 is that the tubular wall 26 becomes slightly flexible, so that the inner diameter of the tubular wall 26 can be slightly augmented by the moving apart of the edges of the tube wall 26 bounding the recess 36. Augmenting the inner diameter of the tube wall 26 can be of benefit when moving the guiding element 24 on the nozzle 20.
  • the tubular wall 26 of the guiding element 24 may be provided with a circumferential groove 38, with a first O-ring 40 received under a bias in the circumferential groove 38, so that recess 36 is pressed closed to some extent and, in mounted condition of the guiding element 24 on the nozzle 20, there is a friction force-based connection between the guiding element 24 and the nozzle 20.
  • the O-ring 40 can exert a permanent tensile force, so that even after prolonged use the guiding element 24 is still firmly clamped on the nozzle 20. Without O-ring 40, as a result of tension relaxation in the plastic of the guiding element 24, the tension of the guiding element 24 on the nozzle 20 could gradually decrease so that the friction resistance between the guiding element 24 and the nozzle 20 could decrease too far to guarantee a stable positioning of the guiding element 24 on the nozzle 20. With the aid of the O-ring 40, the occurrence of this unwanted phenomenon can be prevented.
  • engaging means 42 that can be engaged by hand may be connected to the tubular wall 26.
  • Such engaging means 42 may be configured, when engaged by hand, to bend the tubular wall 26 so that the internal diameter of the guiding element 24 is augmented.
  • the frictional force between the guiding element 24 and the nozzle 20 is reduced, so that adjusting the guiding element 24 with respect to the nozzle 20 and hence with respect to the brush tip can be carried out with less force and hence more accurately.
  • the engaging means with a guiding element 24 that is not provided with an O-ring for creating the squeezing force.
  • the guiding element 24 can for instance have a slightly smaller inner diameter than the outer diameter of the nozzle 20, so that internal stresses in the guiding element already create sufficient squeezing force and hence sufficient frictional force to accomplish a stable attachment of the guiding element 24 on the nozzle 20.
  • the engaging means 42 can for instance be designed as a kind of clothes peg provided with two levers connected to the tubular wall 26 and which can be squeezed together between thumb and index finger so that the inner diameter of the tubular wall 26 is slightly increased and accurate displacement of the guiding element 24 on the nozzle 20 is possible.
  • a cam 44 may be provided which is received in the recess 36 in the tubular wall 26 of the guiding element 24.
  • the mutual engagement between the cam 44 and the recess 36 effects a rotational orientation of the guiding element 24 with respect to the nozzle 20.
  • the painting tool 10 may be provided with a clamping bush 46 in which the proximal end of the brush 14 and the paint supply tube 16 are clamped.
  • the clamping bush 46 may then be provided at an outside surface thereof with an orientation cam 48, whereby the rotational position of the paint supply tube 16 and the orientation cam 46 are mutually fixed.
  • the supply channel 22 of the nozzle 20 can be provided with an orientation recess 50 for receiving the orientation cam 48, such that the rotational position of the clamping bush 46 and hence of the paint supply tube 16 with respect to the nozzle 20 is fixed.
  • the brush 14 is always bent into a curve which is convex on the side of the brush 14 facing the surface to be painted and is concave on the side of the brush 14 facing away from the surface to be painted.
  • the brush hairs extending downstream of the termination of the brush channel 18 in the brush surface together form the brush tip and the paint is therefore, directly upon being dispensed via the brush channel mouth into the brush surface, directly neatly distributed so as to form a line, while with the aid of the brush tip, the boundary of the line can be controlled very accurately.
  • control can proceed so accurately because the at least one guiding point 30, 32, 34 of the guiding element 24 is pressed against one of the surfaces bounding the corner.
  • supporting is done against the two surfaces bounding the corner.
  • the painting tool 10 may be provided with a coupling piece 52 which by a proximal coupling piece end 52p thereof is connected with the paint reservoir 12 and which by a distal coupling piece end 52d thereof is connected with a proximal end 20p of the nozzle 20.
  • the paint reservoir 12 may be implemented as a tube, the tube being provided with a tube wall 54 and a tube mouth 56.
  • the tube mouth 56 in such an embodiment forms a distal mouth edge 56a which extends in a mouth edge plane 56P.
  • the tube wall 54 defines a tube axis 54L which extends perpendicular to the mouth edge plane and which intersects an imaginary center of the mouth edge.
  • the coupling piece 52 is of bent configuration, so that, when the tube 12 is connected with the proximal coupling piece end 52p and the nozzle 20 is connected with the distal coupling piece end 52d, the tube axis 54L and the supply channel axis 22L include an angle ⁇ .
  • This bent coupling piece 52 simplifies the use of the painting tool 10 in that it also makes it easier to cut-in with the painting tool 10 in a corner above one's head, since the tube can be held in a downwardly directed position while the nozzle 20 can then be positioned in a suitable angular position with respect to the surface to be painted (see Fig. 15 ).
  • the axis of the tube and the axis of the nozzle were coaxial, with the result that fairly soon use had to be made of a stepladder to be able to position the nozzle in a proper angular position with respect to the surface to be painted.
  • the angle ⁇ is preferably in the range of 30-60°, and more particularly the angle ⁇ is around 45°.
  • connection between the nozzle 20 and the coupling piece 52 can be a bayonet joint.
  • a bayonet makes quick uncoupling of the nozzle 20 from the coupling piece 52 possible.
  • a fairly large opening is thereby formed, via which the tube can be filled up with paint fairly simply.
  • the bayonet joint is configured to allow different positionings of the nozzle 20 with respect to the coupling piece 52.
  • the above-mentioned perpendicular bisector ML in a first position of the nozzle 20 on the coupling piece 52, the above-mentioned perpendicular bisector ML may be located in a same plane as that in which extend the tube axis 54L and the supply channel axis 22L of the nozzle 20.
  • the perpendicular bisector ML mentioned can extend perpendicular to the plane in which extend the tube axis 54L and the supply channel axis 22L.
  • connection between the tube 12 and the coupling piece 52 can be a screwed connection.
  • Tubes provided with a mouth portion with outer thread are generally known.
  • the present tube 12 is distinguished from the known tubes in that the inner diameter of the mouth portion is relatively large, so that via the tube mouth 56 the tube 12 can be filled with paint and during filling air can escape from the tube.
  • 'Relatively large' in this connection should be understood to mean an inner diameter in the range of around 10-40 mm.
  • 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.
  • the painting tool 10 may be provided with a third O-ring 60 which is included in the connection between the coupling piece 52 and the nozzle 20.
  • the painting tool 10 may be provided with a cap 62 which is placeable on the nozzle 20 and constitutes a substantially airtight shield of the brush 14 from the surroundings.
  • the coupling piece 52 may be provided with at least one planar support surface 52a which is so positioned that when the painting tool 10 lies by the support surface 52a on a horizontal surface, the brush 14, viewed from the proximal brush end 14p to the distal brush end 14d, is directed obliquely upwards.
  • the brush 14 and the nozzle 20 are directed obliquely upwards, which ensures that in such rest condition no paint drips out of the brush 14 when the painting tool is not used.
  • the example of the painting tool 10 that is represented in the figures is provided with two of such support surfaces 52a which are visible in Fig. 15 .
  • Figs. 15 and 16 show the use of the painting tool 10 during cutting-in of a corner 80 between two surfaces 82, 84. Clearly visible is that one, two or all three guiding points 30, 32, 34 are supported against either or both of the surfaces 82, 84. Especially in Fig. 16 it is visible that the brush 14 is slightly bent in that it is pressed against either or both of the surfaces 82, 84. With the aid of the painting tool 10, in a particularly fast manner, that is, much faster than taping up with masking tape or cutting-in freehand, a very straight sharp paint line 86 can be cut-in.
  • the surface 84 can be provided with a layer of paint in a fast and efficient manner using a paint roller 100 with stop 120.
  • the paint roller 100 is implemented in the manner as described in the patent application concurrently filed by applicant(s) which relates to a paint roller 100 provided with a handle 126 nonrotatably connected with the paint roller shaft 106. The contents of that application are considered inserted here.
  • the invention also provides a method which comprises:
  • corners 80 can be cut-in and one or both of the surfaces 82, 84 bounding the corner 80 can be painted.
  • a job chiefly consisting of painting window frames can be carried out no less than two to five times faster than with the aid of conventional painting methods, while the end result is even sharper and, in terms of painting technique, better than can be realized with the conventional painting methods.
  • the method can further include setting the stop 120 by means of turning in an axial direction with respect to the paint roller shaft 106 while the paint roller 100 is held by the handle 126 by the painter.
  • the stop 120 can be appropriately positioned, so that in painting the surface 82 and/or 84, the lateral edge of the cut-in paint line 86 is neatly covered by the paint that is applied with the paint roller 100.
  • the method can also include setting the guiding element 24 with respect to the nozzle 20 and hence with respect to the brush tip 14d. What can thus be realized is that the width and the position of the cut-in paint line 86 during practice of the method can be accurately tuned to the particulars of the respective corner 80, such as, for example, the execution of sealant provided in the corner 80 or the mutual angle between the two surfaces 82, 84.
