    专利说明:

    The invention relates to a paint roller for use with a paint bracket, which paint roller comprises a paint roller surface arranged tangentially about the rotational axis of the paint roller and extending between a first axial end and a second axial end, the paint roller at the second axial end. end includes a bracket receptacle.
    Paint rollers are often used in combination with paint brackets for quick and even painting of larger surfaces. For this purpose, the paint roller surface, for instance of felt, foam or another paint-receiving surface, is provided with paint, after which the paint is delivered to the surface to be painted by rolling the paint roller over the surface to be painted. Because there is also paint on the edges of the paint roller surface, a paint roller cannot easily be used at inside corners or to obtain a tight separation between a painted and an unpainted surface.
    To prevent unwanted transfer in inside corners, the edges are often taped with painter's tape. This is extremely laborious and, especially on uneven surfaces, often ineffective. For example, paint often runs under the tape. The tape must also be removed at the right time. .
    It is now an object of the invention to provide a paint roller for use with a paint bracket, wherein the above drawbacks are reduced or even prevented.
    This object is achieved according to the invention with a paint roller according to the preamble, characterized in that the paint roller comprises a circular spacer disc arranged coaxially with the axis of rotation at the first axial end.
    By attaching a spacer disc to the first axial end, which end in use is closest to an inner corner or dividing line between two surfaces to be painted, unwanted paint transfer can be prevented. The spacer disk prevents the paint roller surface from coming into contact with the surface that meets the painted surface at the inner corner. The spacer disc can then abut against the surface on which no paint is desired.
    By placing the disc coaxial with the axis of rotation, the distance from the circumferential edge of the spacer disc to the edge of the paint roller surface is equal around the entire circumference. This allows easy rolling with the paint roller, without the effect of the spacer disc varying around the circumference.
    In another embodiment of a paint roller according to the invention, the spacer disc is rigidly connected to the first axial end of the paint roller.
    The spacer disc can be easily fitted to the first axial end of the paint roller. For example, the spacer disc can be glued to the material of the paint roller surface, or applied to any hard surface of the paint roller.
    In another embodiment of a paint roller according to the invention, the peripheral edge of the paint roller surface at the first axial end lies in a first plane and the peripheral edge of the spacer disk lies in a second plane, which second plane is parallel to the first plane and wherein the distance between the second face and the second axial end is greater than or equal to the distance between the first face and the second axial end.
    The circumferential edge of the spacer disc maintains the distance from the paint roller surface to the surface not to be painted when in use.
    By arranging the peripheral edge parallel to the peripheral edge of the paint roller surface at the first axial end, the peripheral edge being flush with, or protruding from, the peripheral edge of the paint roller surface at the first axial end, the spacer disc abuts before the paint roller surface come into contact with a surface that should not be painted.
    The parallel arrangement keeps a consistent distance around the entire perimeter.
    Preferably, the distance between the first face and the circumferential edge of the spacer disc is 1mm, so that the spacer disc does not come into contact with paint landing on the first axial end of the paint roller.
    In a preferred embodiment of a paint roller according to the invention, the paint roller surface at the first axial end has an edge diameter that is equal to, preferably greater than, preferably 5 mm greater than, preferably 8 mm greater than the diameter of the distance disc.
    Because the paint roller surface at the first axial end has an edge diameter that is equal to the diameter of the spacer disc, the paint present on the paint roller surface can also be delivered at the edge to the surface to be painted.
    Preferably, the edge diameter is larger than the diameter of the spacer disc, so that the paint roller surface can also be depressed sufficiently at the edge for normal paint delivery.
    The difference between the rim diameter and the diameter of the spacer disc can be adjusted according to how far a normal paint roller is pressed during rolling to obtain good paint delivery.
    The spacer disc still prevents paint from being released to the surface against which the spacer disc abuts.
    Particularly when the edge diameter is 5 mm larger than the diameter of the spacer disc, the paint roller surface can be depressed sufficiently, about 2.5 mm, for example in conventional fur and foam paint rollers.
    When the edge diameter is 8 mm larger than the diameter of the spacer disc, a suitable impression of 4 mm can also be obtained with paint rollers provided with, for example, a fibrous paint roller surface.
    Also an embodiment of a paint roller according to the invention is a paint roller in which the paint roller surface is formed by a paint-receiving layer applied to a core, wherein the diameter of the spacer disc is larger than the diameter of the core. Because the diameter of the spacer disc is larger than the diameter of the core, it is prevented that when the paint roller surface is pressed in, the paint-receiving layer can fold around the core and come into contact therewith with a surface that does not need to be painted. In another embodiment of a paint roller according to the invention, the paint-receiving layer is provided at the first axial end with a recess arranged coaxially with the core. By arranging a recess at the first axial end arranged around the core, it can be prevented that the zone of the paint-receiving layer near the first axial end can absorb too much paint. Because the paint roller surface near the first axial end provides less counter pressure through the recess, the paint roller surface can deform more easily and the paint delivery from the edge zone of the paint roller surface is less sensitive to pressure variations, so that a clean edge line can be obtained more easily. In one embodiment of a paint roller according to the invention, the paint roller surface comprises a first conical section, the diameter in the first conical section decreasing towards the second axial end.
    By providing the paint roller with a partially or fully conical paint roller surface, the paint roller can easily be placed in an inner corner. Because the paint roller comes to be at an angle to the surface to be painted due to the conicity of the paint roller surface, the spacer disc also comes at a greater angle with the adjacent plane of the inner corner, in which case virtually only the circumferential edge of the spacer disc is in contact with it.
    Also according to the invention, is an embodiment of a paint roller wherein the apex angle of the cone intersecting the first conical section of the paint roller surface is 10-30°, preferably 20°.
    Preferably, the apex angle of the cone of which the first conical section of the paint roller surface forms part is between 4-30°. When using the first conical section, the rotation axis then makes an angle between 2-15° with the surface to be painted. Preferably the apex angle is 20°, the axis of rotation making an angle of 10° with the surface to be painted. It has been found that a paint roller with a fully conical paint roller surface having a diameter of 35 mm at the first axial end and a diameter of 19 mm at the second axial end, with a paint roller surface length measured parallel to the axis of rotation of approximately 46 mm. mm, gives very good results.
    In an embodiment of a paint roller according to the invention, the first conical section starts at a first distance from the first axial end, which first distance is greater than or equal to Ô mm, preferably greater than or equal to 8 mm.
    The first conical section can start at the first axial end, i.e. at a distance of 0 mm. This allows the paint roller surface to abut evenly from the first axial end when the paint roller is angled so that the first conical section abuts the surface to be painted. To further control paint delivery, the first conical section begins spaced from the first axial end. The, for example and preferably cylindrical, paint surface between the first axial end and the beginning of the first conical section then, when the paint roller is used at an angle, releases slightly more paint due to the stronger depression of that part of the paint roller surface. This makes it easier to cover the edge completely.
    Also an embodiment of a paint roller according to the invention is a paint roller which also comprises a second conical section adjacent the end of the first conical section opposite the first axial end, wherein the apex angle of the cone forming the first conical section of the the paint roller surface intersecting is greater than the apex angle of the cone intersecting the second conical section of the paint roller surface.
    By providing a second conical section connecting to the first conical section, wherein the first conical section has a more obtuse apex angle, a larger circumference of the paint roller surface is obtained in the zone near or preferably adjacent to the first axial end. In particular, when the first conical section extends to the first axial end, i.e. when the first conical section starts 0 mm away from the first axial end, the paint roller surface can be deformed better under slight compression. Due to the deformation of the circumferential edge of the paint roller surface at the first axial end, this circumferential edge extends slightly beyond the plane in which the first axial end lies at rest. As a result, by adjusting the pressure accurately
    : Determine how far the paint roller surface touches the inner corner.
    Because the second conical section has a sharper apex angle, the difference between the edge diameter of the first axial end and the second axial end is smaller than if the entire paint roller had the more obtuse apex angle of the first conical section.
    It has been found that this makes it easier to paint, because the paint-releasing ability also depends on the diameter.
    In an embodiment of a paint roller according to the invention, the length of the paint roller surface measured parallel to the rotational axis is 50-65%, preferably 60% of the largest diameter of the paint roller surface.
    By making the paint roller surface small in relation to the diameter, a narrow paint roller is obtained that makes it even easier to finish edges.
    It has been found that a paint roller with a largest diameter of 35 mm and a length of the paint roller surface of 20 mm measured parallel to the rotation axis is very convenient.
    When shortening the paint roller surface, it can be advantageous to shorten the core with the bracket accommodation as well.
    This prevents hitting the surface to be painted when the paint roller is used at an angle.
    A smaller paint bracket can also be used if necessary.
    Another preferred embodiment of a paint roller according to the invention is a paint roller in which the paint roller surface flares out towards the first axial end in the shape of a trumpet.
    With a trumpet-shaped flared paint roller surface in the zone near or preferably adjacent to the first axial end, a gradually increasing perimeter of the paint roller surface is obtained.
    In particular when the trumpet shape continues to the first axial end.
    Similar to the embodiment in which the paint roller comprises two conical sections, the deformation of the peripheral edge of the paint roller surface at the first axial end allows the peripheral edge to extend slightly beyond the plane in which the first axial end rests. This makes it possible to accurately determine how far the paint roller surface touches the inner corner by adjusting the pressure.
    The first conical section of other embodiments may also be replaced by a flared trumpet section. A smooth transition can hereby be obtained, which is advantageous for the ease of use of the roller.
    In another embodiment of a paint roller according to the invention, the spacer disc is concave.
    By making the spacer disc concave, the spacer disc only rests with its circumferential edge against the surface that is not to be painted.
    Also according to the invention, there is an embodiment of a paint roller in which the spacer disc is a ring.
    For example, to save weight, the spacer disc can also be designed as a ring.
    Also a preferred embodiment of a paint roller according to the invention is a paint roller wherein the spacer disc comprises metal.
    It has been found to be particularly advantageous to make the spacer disc from metal or a metal alloy. Metal has sufficient stiffness and resilience and is wear-resistant, so that when, for example, an inner corner between a frame and masonry has to be painted, the metal spacer disc is not damaged from contact with the masonry.
    In another embodiment of a paint roller according to the invention, the thickness of the spacer disc decreases in the radial direction.
    While a uniform thickness spacer may work well, a thickening toward the axis of rotation makes the spacer more rigid. As a result, there is less chance of too great a deformation of the circumferential edge of the spacer disc, resulting in undesired paint transfer. The reinforcement can be obtained, for example, by constructing the spacer disc by mounting two discs concentrically on each other, one of the discs having a smaller diameter, for example 4 mm smaller. With discs of equal thickness, the spacer disc thus obtained becomes twice as thick as the thickness of the circumferential edge of the spacer disc.
    Also, a thickening towards the rotation axis helps for angling the paint roller. This makes it easier to apply the paint roller correctly.
    Another embodiment of a paint roller according to the invention is a paint roller in which the circumferential edge of the spacer disc has a thickness of less than 1 mm, preferably 0.2 mm.
    By taking a thin circumferential edge of the spacer disc, with a thickness of less than 1 mm, it is possible to paint very far into the corner. Preferably, the circumferential edge of the spacer disc is 0.2 mm thick. This thickness, especially when the spacer disc is made of a metal or metal alloy, allows a very tight edge finish of the painted surface.
    These and other features of the invention will be further elucidated with reference to the accompanying drawings.

    Figure 6 shows an axial section of a sixth embodiment of a paint roller according to the invention in use.
    Figure 1 shows an axial section of a paint roller 1 according to the invention.
    The paint roller surface 2 extends between the first axial end 3 and the second axial end 4. A bracket accommodation 5 is provided in the second axial end 4 .
    The paint roller 1 has a paint-receiving layer 7 arranged on a core 6 . At the first axial end 3 a spacer disc 8 is arranged coaxially with the axis of rotation 9 .
    The edge diameter 10 of the circumferential edge 11 of the paint roller surface 2 at the first axial end 3 is larger than the diameter 12 of the spacer disk 8. The diameter 13 of the core 6 is smaller than the diameter 12 of the spacer disk 8. The circumferential edge 11 of the paint roller surface 2 at the first axial end 3 lies in the first plane 14. The circumferential edge of the spacer disc 8 lies in the second plane 15. The distance between the second plane 15 and the second axial end 4 is greater than the distance between the first plane 14 and the second axial end 4. Figure 2 shows an axial section of a paint roller 21 according to the invention with a conical paint roller surface 22. The paint roller surface 22 extends between the first axial end 23 and the second axial end 24. In the second At the axial end 24, a bracket receptacle 25 is provided. The paint roller 21 has a paint-receiving layer 27 provided on a core 26. At the first axial end 23, a spacer disc 28 coaxial with the axis of rotation 29 is provided. The edge diameter 30 of the peripheral edge 31 of the paint roller surface 21 at the first axial end 23 is greater than the edge diameter 32 of the peripheral edge 33 of the paint roller surface 21 at the second axial end 24, Fig. 3 shows an axial section of a paint roller 41 according to the invention with a conical, shortened paint roller surface 42. At the first axial end 43, a concave spacer disk 48 coaxial with the rotational axis 49 is mounted. The paint roller 41 has a paint-receiving layer 47 disposed on a core 46. A portion of the cone, having apex angle 45, which intersects the conical paint roller surface 42 is indicated by dashed lines 44 . The peripheral edge 51 of the paint roller surface 42 at the first axial end 43 lies in the first plane 54. The peripheral edge of the concave spacer disk 48 lies in the second plane 55.
    The length 56 measured parallel to the axis of rotation 49 is approximately 60% of the largest diameter 57 of the paint roller surface 42.
    Figure 4 shows a side view of a paint roller 61 according to the invention, with a paint roller surface consisting of a cylindrical section 62 and a conical section 63. The conical section 63 starts at a distance 64, e.g. 8 mm, from the first axial end 65. The bracket holder 66 is shortened, so that it is easier to work at an angle, without touching the surface to be painted with the paint bracket or bracket holder 66.
    The spacer disc 68 is made of two concentric discs 69 and 70. The smallest disc 69 provides strength and ensures correct placement. This allows the larger disk 70 to be thinner.
    For example, a well-functioning sizing is a cylindrical section 62 with a diameter of 30 mm, with the conical section 63 starting at 8 mm from the first axial end or edge of the paint roller surface. The smallest diameter of the paint roller surface 62, 63 is at the edge 71 of the paint roller surface 62, located near the bracket holder 66.
    63. For example, this diameter is 20 mm.
    The edge diameter of the spacer disc 68 is formed by the largest disc 70 and is, for example, 26 mm. For example, the diameter of the smaller disc 69 is 22 mm. At a thickness of 0.2 mm of the discs 69 and 70, the total thickness of the spacer disc 68 is then 0.4 mm. Thus, the thickness of the spacer disc decreases in the radial direction.
    Figure 5 shows an axial section of a paint roller 81 according to the invention with a trumpet-shaped flared section 82 and a subsequent second conical section 83. At the first axial end 84 a convex spacer disc 85 is arranged coaxially with the rotation axis 86.
    The paint roller 81 has a paint-receiving layer 88 applied to a core 87. The spacer disc 85 is spaced 89 from the plane 90 in which the peripheral edge 91 of the paint roller surface lies at the first axial end 84. A recess 92 provided in the paint-receiving layer 88 at the first axial end 84 ensures that the peripheral edge 91 can, among other things, deform more easily. The recess 92 can be trumpet-shaped, but other shapes such as a cylindrical or conical recess can also be used, for example, depending on the material from which the paint-receiving layer 88 is made. The depth of the spacer disc 85 relative to the core 87 is limited by a ridge 93 arranged in the core 87. Because the bracket of the paint roller rests in the receptacle 94 of the spacer disc 85 in use, the spacer disc 85 can simply be pressed out of the core 87 by pressing the bracket in the direction of the spacer disc 85. This can, for example, simplify cleaning.
    Figure 6 shows an axial section of a paint roller 101 according to the invention in use. The paint roller holder bracket is not shown. The paint roller 101 differs from the embodiment 81 of Fig. 5 in that no recess is provided and in that the spacer disc 105 abuts the first axial end 84 . The other corresponding features are therefore assigned the same reference numerals. In the inner corner 102 of the frame 103 it is clearly visible that the circumferential edge 391 is deformed because the trumpet-shaped section 82 abuts flush against the frame 103 to be painted. Due to the conical section 83 the paint roller 101 comes at an angle to the frame 103 to be painted. to lay down. As a result, due to the contact at point 104 of the spacer 85 against the opposite frame part 106, together with the deformation of the trumpet-shaped section 82, the inner corner 102 is accurately touched by the paint roller 101. As a result, an inner corner can be painted very easily, without paint gets on the opposite part 106 of the frame. The distance between the contact point 104 of the spacer disc 85 on the frame 106 is selected depending on the possible deformation and shape of the paint roller, so that the peripheral edge 91 ends in the inner corner 102 during use. This effect is independent of whether or not the spacer disc abuts the first axial end and is thus also obtained with, for example, the spacer disc 85 of the embodiment of figure 5. Due to the shape of the spacer disc 105, the abutment point 104 can also be placed on another point of the curvature with the same effect.
    A particular advantage of the paint roller 101 is that the spacer disc 105 abuts the first axial end 84 of the paint receiving layer 88 and preferably compresses the paint receiving layer 88 slightly.
    This prevents the build-up of paint through the layer 88 towards the spacer disc 105, so that it remains clean and does not release paint undesirably.
    In order to obtain sufficient depression of the paint-receiving layer 88, the core 87 may optionally be set back slightly at the first axial end relative to the paint-receiving layer 88.
