FIELD OF THE INVENTION
[0001] The present invention relates to apparatuses for applying paint and other liquid
coatings to surfaces, and more particularly, to apparatuses for creating customized
patterns.
BACKGROUND OF THE INVENTION
[0002] Paint applicators are generally used to apply paint to surfaces such as walls, ceilings,
floors, objects (e.g., cars, boats, or the like), etc. One type of typical paint applicator
includes a frame, a handle coupled to one end of the frame, and a roller cage rotatably
coupled to the other end of the frame. The cage is configured to slideably receive
a single replaceable paint roller that spans substantially the entire length of the
roller cage. The paint roller includes a core and a paint absorbing material covering
the core, which is generally made of simulated lambs wool or other cellular material
that can retain paint. In use, the applicator is rolled through a paint reservoir
so that the material on the roller absorbs or takes up paint. The roller may include
a textured surface so that the roller delivers a patterned coating. Conventional textured
rollers are configured to span the entire length of the cage; that is, the core is
substantially the same length as the roller cage. As such, the variety of possible
patterned coatings is dictated by rollers made available for purchase from the manufacturers.
[0003] Although the described systems may be used to create attractive patterns, the conventional
roller has several disadvantages. Because the roller is one piece, the roller frame
can only be used for applying one texture or pattern. As a result, the conventional
roller frame is limited to the particular texture or a particular pattern that is
provided to the roller and cannot be customized by the user according to his or her
tastes or the requirements of an application. Because the rollers span the entire
roller cage, desirable complex or customized patterns are complex and expensive.
[0004] Thus, there is a long felt need to provide a paint applicator that permits the user
to customize the patterns and textures of paint delivered by the applicator.
SUMMARY OF THE INVENTION
[0005] The present invention relates to a modular applicator kit for use with a liquid applicator.
The modular applicator kit includes a plurality of segments adapted to be coupled
to the liquid applicator. Each segment includes a core, a raised portion supported
by the core and configured to contact and transfer paint to a surface, and a depressed
portion configured to not contact the surface.
[0006] The present invention also relates to a method of providing a paint roller for use
in applying a decorative effect to a surface. The method includes positioning a first
segment having a first decorative effect on the paint roller and positioning a second
segment having a second decorative effect that is different from the first decorative
effect on the paint roller.
[0007] The present invention also relates to a liquid applicating system. The liquid applicating
system includes a liquid applicator and a plurality of segments coupled to the liquid
applicator. Each segment includes a core, a raised portion supported by the core and
configured to contact and transfer paint to a surface, and a depressed portion configured
to not contact the surface.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0009] FIG. 1 illustrates a paint applicator 10 for applying a paint to a surface. Paint
applicator 10 includes a frame 12 and a modular applicator kit 14 having segments
16. Frame 12 is configured to rotatably support modular applicator kit 14 and may
be manufactured using conventional manufacturing techniques associated with single
shafted paint applicator. Frame 12 includes a handle 18, a shaft 20, and a roller
cage 22. Roller cage 22 is rotatably supported about shaft 20 and is configured to
support segments 16 about an axis A of shaft 20. As shown in FIG. 3, shaft 20 is a
single elongate rod extending through roller cage 22 to rotatably support cage 22
about axis A. Cage 22 includes a pair of hubs 24 journaled about shaft 20 and interconnected
by wires 26. Wires 26 are outwardly angled for frictional engagement with inner circumferential
surfaces of segments 16. As a result, wires 26 prevent slippage or rotation of segments
16 relative to roller cage 22. According to an alternative embodiment, roller cage
22 may comprise other known cage structures integrally formed from plastic. According
to alternative embodiments, handle 18, shaft 20, roller cage 22, hubs 24, or wires
26 may be formed from any number of plastic materials.
[0010] Modular applicator kit 14 includes a plurality of interchangeable segments 16. Segments
16 are generally tubular-shaped and are sized for being interchangeably positioned
over and about roller cage 22 and removable from roller cage 22 for cleaning or replacement.
As shown in FIGS. 1 and 2, segments 16 each include a rigid, tubular core 28, a depressed
portion 30, and a raised portion 32. Core 28 is configured to support segments 16
upon roller cage 22 and is made from a plastic. According to a preferred embodiment,
core 28 is formed from a multiplicity of spirally-wound, polypropylene plies that
are wrapped around a fixed mandrel and bonded together by heating and contact engagement
of the plies. Forming
core 28 is further illustrated in U.S. Patent No. 5,206,968, the full disclosure of which
is hereby incorporated by reference. According to an alternative embodiment, core
28 is formed from a single spirally-wound ply that is wrapped around a fixed mandrel
and bonded together by heating and contact engagement of adjacent plies. According
to an alternative embodiment, core 28 is formed by extrusion and cut to desired widths.
According to alternative embodiments, core 28 is made from any number of a variety
of materials, including cardboard, fiberboard, metal, or the like.
[0011] As shown in FIGS. 1 and 3, depressed portion 30 and raised portion 32 are disposed
along the axial length and circumference of segments 16. Depressed portion 30 is configured
to not contact the surface and to provide spacing between adjacent raised portions,
which may or may not be on the same segment or on adjacent segments. Raised portion
32 provides a membrane 34 made from liquid absorbent material and is configured to
contact the surface receiving the paint or liquid. Membrane 34 is made from a thermoplastic
material such as acrylic, blended acrylic, or polyester fiber nap, and is configured
to carry paint or other liquids (such as varnish, stain, primer, adhesive, lubricant,
etc.) that are being applied upon a surface. According to alternative embodiments,
membrane 34 may be made from any number of liquid absorbent materials including wool,
simulated lambs wool, open-celled material (such as foam, or sponge), closed cell
material, and material having liquid absorbent characteristics, or the like.
[0012] Membrane 34 is affixed to core 28. According to a preferred embodiment, membrane
34 is bonded or fused to core 28 by heating the exposed outer surface of core 28 (e.g.,
by gas ribbon burners) and applying membrane 34 in strip-form. Affixing membrane 34
to core 28 using heat is further illustrated in U.S. Patent No. 5,206,968 and U.S.
Patent No. 5,468,207, the full disclosures of which are hereby incorporated by reference.
According to an alternative embodiment, membrane 34 is bonded or fused to core 28
by applying an adhesive to the outer surface of core 28 and then applying membrane
in strip-form thereto. Affixing membrane 34 to core 28 using an adhesive such as liquid
polypropylene is further illustrated in U.S. Patent No. 5,572,790, the full disclosure
of which is hereby incorporated by reference. According to alternative embodiments,
membrane 34 is affixed to core 28 by double sided tape, interference-fit, or the like.
[0013] According to a preferred embodiment, depressed portion 30 and raised portion 32,
which provide the decorative effect (e.g., pattern, texture, etc.) is formed by exposing
membrane 34 to a heating element, which causes the exposed material to shrink down
(e.g., melt, burn, singe, etc.). Forming depressed portion 30 and raised portion 32
using heat as further illustrated in an earlier filed, commonly owned U.S. patent
application, U.S. Serial No. 09/134,554 titled "Method and Apparatus for Forming a
Decorative Pattern in a Liquid Coating Applicator" and filed August 14, 1998, the
full disclosure of which is hereby incorporated by reference. Alternatively, depressed
portion 30 and raised portion 32 are formed by a chemically shrinking, melting, burning,
dissolving, or weakening (such that material may be removed to form depressed portion
30). According to alternative embodiments, depressed portion 30 is formed by any number
of a variety of methods for mechanically removing portions of membrane 34 such as
shearing or cutting.
[0014] To prepare paint applicator 10 for use, segments 16 are selected by the user (e.g.,
as having the desired pattern or texture) and are inserted in the desired order onto
roller cage 22. Modular applicator kit 14 is versatile such that selection and arrangement
of segments 16 may be made by the user or as the application requires. As further
shown in FIGS. 1 and 3, segments 16 may be variably positioned in any number of a
variety of combinations or permutations and may have any number of a variety of decorative
depressed portions 30 and raised portions 32 to provide an ornamental or decorative
application. By selectively using and loading a variety of segments 16 on roller cage
22, the user may vary the width of the stripes as well as the spacing between the
stripes being created upon the wall or other surface.
[0015] Segments 16 are successively located on roller cage 22 in close proximate relation
to one another (e.g., configured to be in successively adjacent relation to one another)
and have a variable axial length such that the total number of units span substantially
the units entire length of cage 22. As such, a greater or lesser number of segments
may be inserted on roller cage 22 (e.g., seven according to the embodiment illustrated
in FIG. 3), which is intended to provide more customization and interchangeability,
and provide a greater variety of patterns. According to a preferred embodiment, the
core of one segment is in contact with the core of an adjacent segment. As can be
appreciated, roller cage 22 as well as segments 16 may be axially spaced from one
another about shaft 20 by a variety of distances and by a variety of alternative structures.
For example, raised portion 32 of segments 16 may be positioned away from one another
by utilizing a spacer 36 (i.e., a segment that does not have membrane 34 or raised
portion 32) between adjacent segments 16 having raised portions 32. In lieu of spacer
36, other structures could be used for slidably positioning segments 16 along roller
cage 22 to provide the desired spacing therebetween. According to an alternative embodiment,
the core of one segment is not in contact with the core of the adjacent segment.
[0016] Segments 16 are configured for creating any number of a variety of patterns and/or
textures. As shown in FIGS. 1 and 3, the pattern may be applied by raised portions
that are generally linear stripes of varying widths 38, 40a and 40b, zig-zag stripes
42, circular or dotted patterns 44, diagonal stripes 46, arcuate stripes 48, diagonal
stripe segments 50, or the like on a surface (such as a wall, floor, ceiling, automobile,
articles of manufacture, or the like). Patterns may be created by a plurality of raised
portions 32 on a single segment (for example, narrower linear stripe 38 and wider
linear stripe 40a, and diagonal stripe segments 50). Additionally, segments 16 are
configured for creating any number of a variety of textures such that similar patterns
having different textures provide a different decorative effect. As shown in FIG.
3, linear stripe 40a is provided with a different texture than linear stripe 40b.
Different textures may be provided by using different membrane materials or material
configurations (e.g., acrylic and polyester fabric, foam, looped fabric nap, etc.).
Such different membranes may be used on separate segments or on separate raised portions
on a single raised portion. Additionally, stripes of multiple colors may be applied
when modular applicator kit 14 is used in conjunction with a multi-compartmentalized
tray containing different color paints.
[0017] According to a preferred embodiment, frame 12 and/or modular applicator kit 14 are
configured to prevent segments 16 from rotating with respect to each other or with
respect to roller cage 22. According to a particularly preferred embodiment shown
in FIG. 3, shaft 20 of frame 12 further includes a threaded portion 52 located at
an end 54 of shaft 20. Threaded portion 52 is configured to threadably receive a retaining
cap 56. According to alternative embodiments, retaining cap 56 couples to shaft 20
by any number of attachment methods, including an interference-fit, snap fit, quick
release, or the like. A shoulder 58 is disposed at the opposite end of roller cage
22. Retaining cap 56 and shoulder 58 are configured to secure segments 16 in place
and to prevent segments 16 from sliding longitudinally along roller cage 22 and to
provide friction between adjacent segments 16 to prevent rotation of segments 16 relative
to each other or relative to roller cage 22 while still enabling roller cage 22 to
rotate about shaft 20. According to an alternative embodiment, segments 16 are sized
to provide an interference fit with roller cage 22 (e.g., an inner diameter of the
segment is approximately equal to the outer diameter of the roller cages).
[0018] According to an alternative embodiment (shown in FIG. 4), segments 16 are configured
to prevent rotation relative to an adjacent segment. Segments 16 each includes a cleat
60 and a notch 62 configured to receive cleat 60 of the adjacent segment. When cleat
60 and notch 62 are engaged, the segments uniformally rotate about the shaft. According
to an alternative embodiment, segments 16 are keyed to roller cage 22 or keyed to
shaft 20 such that the segments do not rotate relative to the cage or one another.
[0019] Thus, modular applicator kit 14 provides several advantages over known conventional
paint supply and finishing systems. First, the user may select and employ any number
of a variety of segments 16 and combinations and presentations thereof to create different
patterns and textures. Such a variable selection provides for a customized application.
Further customization may be attained by employing a multi-compartmentalized tray.
Second, segments 16 are mounted to the roller cage such that the segments do not rotate
relative to each other and are slidably fixed to roller cage 22. Such a configuration
is intended to provide a consistent deposition of liquid.
[0020] As will be appreciated, modular applicator kit 14 may have various other configurations
while still embodying the concepts of the present invention. For example, applicator
kit 14 may be configured for use with an alternative roller frame 12 configured to
support greater than one roller cage and additional segments along shaft 20. In lieu
of being removable from roller cage 22, each segment 16 may alternatively be integrally
formed with roller cage 22 as a single unitary body or may be directly rotatably coupled
to shaft 20 without the use of roller cage 22. Those skilled in the art will appreciate
that certain of these advantages can be obtained separately through reconfiguring
the foregoing structure without departing from the spirit and scope of the present
invention. Additionally, although a paint applicator is discussed herein, it can be
appreciated that the modular applicator kit may be employed in any number of a variety
of applications wherein a liquid is applied to a surface.
[0021] Although the present invention has been described with reference to preferred embodiments,
persons skilled in the art will recognize that changes may be made in form and detail
without departing from the spirit and scope of the invention. The present invention
