Description
BACKGROUND OF THE INVENTION
1. Technical Field
The invention generally relates to the field of painting using roller paint brush covers and more specifically relates to the field of removing roller paint brush covers still containing wet paint from the handle framework and removing paint from and cleaning these roller paint brush covers. The invention further relates to methods and systems for handling roller paint brush covers containing wet paint, methods and systems for removing wet paint from roller paint brush covers, and methods and systems for cleaning wet paint from roller paint brush covers. The invention further relates to a devices and combinations of devices that can be used to stir and mix paint, remove roller paint brush covers from the handle framework, remove paint from and clean roller paint brush covers, and methods and systems for accomplishing these actions.
2. Prior Art
Likely the most well-known method of dealing with roller paint brush covers is to grasp the wet roller paint brush cover, pull it off of the handle framework, throw it away, and go out and purchase a new roller paint brush cover for the next painting job. Those that are more adventurous will wash the roller paint brush cover in the appropriate cleaning solution (such as water or soapy water for water-based paints, and suitable other solvents for water-insoluble paints), air dry it, and reuse it for the next painting job. Either way, removing the roller paint brush cover when wet from the handle framework can be a messy adventure, and cleaning the roller paint brush cover for reuse even more so.
Similarly, likely the most well-known method of stirring or mixing paint is either by using a stirring stick, which can be messy, or by vigorously shaking the paint can, which can be difficult to do properly unless you happen to have a can shaker, which can be expensive. Stirrers are known, including powered stirrers and stirrers attached to power drills. However, these stirrers do not have a protective cage surrounding the impellers to prevent damage and injury and to allow stirring proximal to the side of the container.
The economically and/or ecologically minded prefer washing and reusing the roller paint brush cover. For them, several different devices are available. For example, U.S. Pat. No. 3,436,264 to Allen discloses an apparatus for cleaning paint roller covers. The Allen '264 device comprises an expandable spindle for inserting into and holding the roller paint brush cover. The spindle is mounted on a power drill and the roller paint brush cover is rotated within a bag or other disposable device to remove the paint by centrifugal force. However, the Allen '264 device uses an expandable spindle, which adds to the complexity of the device, and does not comprise a device for removing the roller paint brush cover from the handle framework or the spindle, and therefore does not prevent the messes associated with such an operation.
Similarly, U.S. Pat. No. 4,545,395 to Kolb discloses a paint roller apparatus with inherent cleaning capability. The Kolb '395 device is a unitary device that can be used for roller brush painting and, when the painting is finished, cleaning the roller brush. Specifically, the Kolb '395 device comprises a handle and a roller on which a roller paint brush cover is mounted. The roller comprises means for attaching to a power drill such that after painting, the roller can be spun clean. However, the Kolb '395 device is a unitary device, and does not appear to be suitable for the common roller painting apparatus. Further, the Kolb '395 device also does not have a device for removing the roller paint brush cover from the handle.
U.S. Pat. No. 4,263,055 to Permar and U.S. Pat. No. 5,539,948 to McCauley disclose simple devices that can be inserted into the center of a roller paint brush cover and mounted on a power drill for spin cleaning. U.S. Pat. No. 6,116,255 to Walter, U.S. Pat. No. 5,626,158 to Gratopp, and U.S. Pat. No. 4,311,158 disclose stand alone devices for spinning and cleaning roller paint brush covers. U.S. Pat. No. 6,088,933 to Mallalieu discloses a hand-operated spin cleaning device for roller paint brush covers. However, none of these devices combine the spin cleaning device with a device for removing the roller paint brush cover from the handle framework.
Thus it can be seen that there is a need for a simple and economical device, method and system for cleaning roller paint brush covers and for handling the roller paint brush covers during the cleaning process. It can also be seen that there is a need for an improved device for stirring and/or mixing paints, stains and other coatings and liquids. It is to these needs and other related needs that the present invention is directed.
BRIEF SUMMARY OF THE INVENTION
The invention briefly described is a device, method and system for cleaning paint from paint roller brushes. The invention comprises a gripping device for removing a paint roller brush from the handle framework, a holding device for holding the paint roller brush during the paint removing and cleaning process, and a mounting device for connecting the holding device with the paint roller brush to a motor or other motion imparting means. The invention further comprises a device attached to the holding device for stirring and mixing paint.
The gripping device comprises a generally cylindrical tube mounted on a handle. The generally cylindrical tube comprises open ends and can comprise a solid cylindrical wall or a cylindrical wall having an open slot along its length. The open slot can extend along the entire length of the generally cylindrical tube to provide a passageway for a support rod of the handle framework to pass as the roller paint brush cover and the gripping device are moved to remove the roller paint brush cover from the handle framework. The inner diameter of the generally cylindrical tube should be approximately the same as or slightly larger than the outer diameter of the roller paint brush cover. Alternatively, the inner diameter of the generally cylindrical tube can be relatively large so as to be able to accommodate different roller paint brush covers having a wide variety of diameters.
One end, the insertion end, of the gripping device preferably is completely open so as to allow the insertion of the roller paint brush cover. The other end, the tail end, can also be completely open, but optionally can be closed, partially closed, or comprise a tab for contacting and pushing the roller paint brush cover off of the handle framework. The handle is attached to the generally cylindrical tube along the cylindrical wall in such location allowing the user to hold the generally cylindrical tube but not interfering with the open ends of the generally cylindrical tube. Grippers of various diameters can be made for paint roller brushes of various diameters, or a single gripper having a relatively large, or having a variable, diameter can be made for use with several different diameters of roller paint brush covers.
The holding device comprises a cage-like frame similar or identical to the known cage-like frames on which paint roller brushes are mounted for use. The cage-like frame generally is cylindrical in shape, the cylindrical shape being formed by a plurality of wires or rods extending the length of the cylindrical shape. End caps, rings or other devices can be used to hold the plurality of wires or rods together in the generally cylindrical shape. The outer diameter of the holding device preferably is approximately the same as the inner diameter of the paint roller brush such that the paint roller brush can be mounted and held securely on the holding device. Optionally, the holding device can have an outer diameter slightly larger than the inner diameter of the paint roller brush, or can be a flexible or spring-like construction, to increase the holding power.
The mounting device comprises a shaft or rod that is attached securely to and extends axially from the holding device. The mounting device can extend along the entire or partial length of the holding device, in which case it would be positioned as the central axis, or it can be attached at an end of the holding device and extend outwardly and axially from the holding device. In any construction, the mounting device extends a suitable distance outwardly and axially from the holding device so as to mountable in the motor or other motion imparting device.
The motor or other motion imparting device preferably provides rotational motion to the mounting device, and thus to the holding device and any paint roller brush on the holding device. A hand or power drill or other such motor-driven device is suitable.
In use, a house, wall, ceiling or other structure or surface has been painted using a roller paint brush cover, the roller paint brush cover generally remains loaded with some paint. Rather than removing the loaded roller paint brush cover from the handle framework with the hands, gloves or other means that would then become soiled and/or ruined, the user of the invention grasps the handle of the gripping device and slides the gripping device over the loaded roller paint brush cover. Handle frameworks typically have a singe shaped rod extending from a handle and terminating in a roller paint brush cover holding end after bending through a series of curves, thus holding the roller paint brush cover from one end. A typical representation of a handle framework is shown in FIG.
1
. The griping device is placed over the loaded roller paint brush cover with the support rod of the handle framework passing through the slot in the generally cylindrical tube. If the gripping device comprises a closed or partially closed end, or a pushing tab, this will assist in pushing the roller paint brush cover off of the handle framework. Alternatively, the gripping means can be structured to hold the roller paint brush cover securely enough to remove the roller paint brush cover from the handle framework without the need for a closed or partially closed end, or a pushing tab.
The user then transfers the loaded roller paint brush cover onto the holding device in generally the opposite manner as the roller paint brush cover was removed from the handle framework. The user slides the roller paint brush cover onto the cage-like structure of the holding device and then removes the gripping device, leaving the roller paint brush cover on the holding device. The holding device either already is mounted on or then is mounted on the motor or motion imparting device. The motor or motion imparting device can be a power drill or a similar device.
The loaded roller paint brush cover then is placed into a bucket or other container of water or soapy water (for water soluble paints) or other solvent (for water insoluble paints) and the motor or other motion imparting device activated. The roller paint brush cover is spun around in the cleaning solution for a period of time sufficient to remove the paint from the roller paint brush cover. This step can be repeated any number of times to achieve the level of cleaning desired. The roller paint brush cover then can be spun in a bucket of clean water to rinse cleaning solution from the roller paint brush cover. After the roller paint brush cover has been cleaned, the roller paint brush cover then can be spun in an empty bucket, cylinder or other structure, or in the open, to remove any excess water or cleaning solution and to spin dry the roller paint brush cover. The roller paint brush cover now has been restored to a clean or cleaner state for reuse.
The invention also includes a device for stirring and/or mixing paints, stains and other coatings and fluids. The stirring device is a modification of the holding device and comprises a cage-like frame similar or identical to the known cage-like frames on which paint roller brushes are mounted for use. The cage-like frame generally is cylindrical in shape, the cylindrical shape being formed by a plurality of wires or rods extending the length of the cylindrical shape. End caps, rings or other devices can be used to hold the plurality of wires or rods together in the generally cylindrical shape. The stirring device has rod as the central axis, which generally is a continuation of the shaft or rod of the mounting device. The stirring device can be one or more impellers or other suitable mixing component. In use, the stirring device is mounted via the mounting device on a motor or other motion imparting device and the stirring device is placed in the liquid to be stirred or mixed. The motor or other motion imparting device is activated and the stirring device acts on the liquid. The cage-like frame also can assist in stirring and/or mixing the liquid, and further allows stirring and/or mixing right up to the side of the container as the cage-like frame can contact the container without damaging the container.
The invention also is a system for cleaning roller paint brush covers comprising the gripping device, the holding device and the motor or motion imparting device, and a method for cleaning roller paint brush covers using the devices and systems of the invention. The features and advantages of the present invention will become even more apparent to those of ordinary skill in the art when the following detailed description of the preferred embodiments is read in conjunction with the appended figures in which like reference numerals designate like parts throughout the several views.

Referring now generally to the FIGS., the invention comprises a gripping device
30
for removing a paint roller brush
12
from the handle framework
14
of a painting device, a holding device
50
for holding the paint roller brush
12
during the paint removing and cleaning process, and a mounting device
70
for connecting the holding device
50
with the paint roller brush
12
to a motor or other motion imparting means
90
. The invention further comprises a propeller device
82
attached to the holding device
50
for stirring and mixing paint.
Referring now to
FIGS. 7-12
, the gripping device
30
comprises a generally cylindrical tube
32
mounted on a handle
34
. Handle
34
is for grasping by the user and can be any suitable shape, such as the exemplary pistol grip shape shown in the FIGS. The generally cylindrical tube
32
comprises two ends, insertion end
36
and tail end
38
and can comprise either a solid cylindrical wall
40
or preferably a cylindrical wall
40
having an open slot
42
along its length. Although the length of cylindrical tube
32
generally is unimportant, it preferably is no longer than the length of a typical roller paint brush cover
12
, which is between approximately 2 inches (5 cm) and 9 inches (23 cm), depending on the size and type of roller paint brush cover
12
used. Thus, the cylindrical tube
32
can be made of many different lengths to accommodate many different lengths of roller paint brush covers
12
. For the typical 9 inch (23 cm) roller paint brush cover
12
, the cylindrical tube
32
more preferably no longer than 6 inches (15 cm), and even more preferably between 2 inches (5 cm) and 6 inches (15 cm) in length. A cylindrical tube
32
having a length of 2 inches (5 cm) can be used for most lengths of roller paint brush cover
12
. Having a length shorter than the length of the roller paint brush cover can allow the user to pull the roller paint brush cover
12
out of the gripping device
30
if necessary.
The inner diameter of the generally cylindrical tube
32
preferably is approximately the same as or slightly smaller or larger than the outer diameter of the typical roller paint brush cover
12
, including the nap, which is between approximately 1 inch (2.5 cm) and 3 inches (7.5 cm). Alternatively, the inner diameter of the generally cylindrical tube
32
can be relatively large, such as for illustrative purposes 3 inches (7.5 cm) or larger up to 4 inches (10 cm) or 5 inches (12.7 cm), so as to be able to accommodate different roller paint brush covers
12
having a wide variety of diameters. Having a diameter greater than the diameter of the roller paint brush cover
12
can prevent the roller paint brush cover
12
from becoming lodged in the gripping device
30
. Similarly, having a diameter less than the diameter of the roller paint brush cover
12
can assist in retaining the roller paint brush cover
12
within the gripping device
30
. Thus, gripping devices
30
of various diameters can be made for paint roller brushes
12
of various diameters, or a single gripping device
30
having a relatively large, or having a variable, diameter can be made for use with several different diameters of roller paint brush covers
12
.
The open slot
42
can extend along the entire length of the generally cylindrical tube
32
to provide a passageway for a support rod
16
of the handle framework
14
to pass as the roller paint brush cover
12
and the gripping device
30
are moved to remove the roller paint brush cover
12
from the handle framework
14
. As can be seen in the FIGS., a typical handle framework
14
comprises a metal or other material rod
16
bent to accommodate the roller paint brush cover
12
. Rod
16
typically is on the order of ¼ inch (0.6 cm) to ⅝ inch (1.3 cm) in diameter or thickness. Therefore, to accommodate the majority of rods
16
, open slot
42
preferably is between ¼ inch (0.6 cm) and ¾ inch (1.9 cm) wide, that is, from one edge of cylindrical tube
32
to the other edge. Further, as the open structure of cylindrical tube
32
due to slot
42
can cause cylindrical tube
32
to be somewhat flexible, that is cylindrical tube
32
and open up slightly to a larger diameter due to the presence of slot
42
, the width of slot
42
itself can be increased by sliding rod
16
through it if the diameter of rod
16
is larger than the width of slot
42
.
The insertion end
36
of the gripping device
30
preferably is completely open so as to allow the insertion of the roller paint brush cover
12
. The tail end
38
can also be completely open, but optionally can be closed, partially closed, or comprise one or more stopping devices
44
for contacting and pushing the roller paint brush cover
12
off of the handle framework
14
. As shown in
FIG. 8
, stopping devices
44
can be tabs
44
A extending radially inwardly proximal to tail end
38
. Preferably, tabs
44
A extend inwardly from cylindrical tube
32
between approximately {fraction (3/16)} inch (0.5 cm) and ½ inch (1.3 cm). As shown in
FIG. 11
, stopping device
44
can be a toroidal or doughnut shaped inwardly extending extension
44
B of cylindrical tube
32
, or a toroidal or doughnut shaped insert that is secured within cylindrical tube
32
, proximal to or at tail end
38
. The use of a toroidal or doughnut shaped stopping device
44
has some advantages in that the slope of the structure, such as for example having an increasing diameter from proximal to tail end
38
inward along cylindrical tube
32
, generally matches the side slope of many roller paint brush covers
12
and provides a continuous touch point for the inner cylindrical tube of the typical roller paint brush cover
12
. However, for illustrative purposes, the tail end
38
can be completely closed, be partially closed with a central or radial holes, a series of tabs, a grill or mesh, one or more radial or chordal slats extending across tail end
38
, or a toroidal or doughnut shaped inwardly extending extension or insert secured within cylindrical tube
32
, as stopping devices
44
. For ease of cleaning, it is preferable for tail end
38
to have some open portion.
The handle
34
is attached to the generally cylindrical tube
32
along the cylindrical wall in such location allowing the user to hold the generally cylindrical tube
32
but not interfering with the ends
36
,
38
of the generally cylindrical tube
32
. As shown in the FIGS., handle
34
is located opposite slot
42
and proximal to tail end
38
. However, handle
34
can be located at any position on the circumference and along the length of cylindrical tube
32
. Further, handle
34
can be molded as part of cylindrical tube
32
or can be attached later, either permanently or releasably.
The holding device
50
as shown illustratively in
FIGS. 4 and 10
comprises a cage-like frame
52
similar or identical to the known cage-like frames on which paint roller brushes are mounted for use during painting. Such cage-like frames
52
are known in the art and generally cylindrical in shape, the cylindrical shape being formed by a plurality of wires or rods
54
extending the length of the cylindrical shape. Optionally, the cage-like frame
52
can be replaced with a solid or perforated cylinder or the equivalent. End caps
56
,
58
rings or other devices can be used to hold the plurality of wires or rods
54
together in the generally cylindrical shape, and can have flow holes
62
therethrough to allow liquid within the interior of roller paint brush cover
12
to flow out. The outer diameter of the holding device
50
preferably is approximately the same as the inner diameter of the paint roller brush
12
such that the paint roller brush
12
can be mounted and held securely on the holding device
50
. Optionally, the holding device
50
can have an outer diameter slightly larger than the inner diameter of the paint roller brush
12
, or can be a flexible or spring-like construction, to increase the holding power.
Many different sized holding devices
50
can be made to accommodate the various different sized roller paint brush covers
12
. For example, roller paint brush covers
12
having inner diameters of 1 inch (2.5 cm) would require a holding device
50
with a similar outer diameter, while roller paint brush covers
12
having an inner diameter of 2 inches (5 cm) would require a holding device
50
with a similar larger outer diameter. Likewise, for example, roller paint brush covers
12
having a length of 3 inches (7.5 cm) would require a holding device
50
with a similar length, while roller paint brush covers
12
having a length of 9 inches (23 cm) would require a holding device
50
with a similar longer length. A holding device
50
having a length of 9 inches (23 cm) could accommodate a wide range of lengths of roller paint brush covers
12
, including roller paint brush covers
12
having lengths longer and shorter than 9 inches (23 cm).
The mounting device
70
as shown illustratively in
FIGS. 13 and 14
comprises a shaft or rod
72
that is attached securely to and extends axially from the holding device
50
. The mounting device
70
can extend along the entire or partial length of the holding device
50
, in which case it would be positioned as the central axis, or it can be attached at an end of the holding device
50
and extend outwardly and axially from the holding device
50
. In any construction, the mounting device
70
extends a suitable distance outwardly and axially from the holding device
50
so as to mountable in the motor or other motion imparting device
90
.
As can be seen in more detail in
FIG. 14
, mounting device
70
comprises shaft or rod
72
that extends from one end cap
56
of holding device
50
through a second end cap
58
of holding device
50
, and then outward radially a certain distance from second end cap
58
. The length of shaft or rod
72
extending outwardly from holding device
50
is such that it can be inserted securely into any mounting part of motor or other motion imparting device
90
. For example, if motor or other motion imparting device
90
is a power drill, shaft or rod
72
preferably should be at least 1 inch (2.5 cm) so as to fit within power drill chuck
92
. Preferably, shaft or rod
72
is between 2 inches (5 cm) and 10 inches (25 cm) in length, and more preferably between 6 inches (15 cm) and 9 inches (23 cm). It has been found that an 8 inch (20 cm) length provides a suitable compromise between allowing the user to maintain the invention at a suitable distance from the user to prevent splattering of paint and cleaning solution and allowing for a smooth rotation.
The end of the mounting device
70
distal from the holding device
50
can comprise a formed end
74
for secure mounting within the motor or other motion imparting device
90
. For example, as shown in
FIGS. 4
,
5
and
13
, formed end
74
is formed to complement the chuck of a power drill used as the motor or other motion imparting device
90
. Such a formed end is optional, and can be custom formed for a particular motor or other motion imparting device
90
or type of motor or other motion imparting device
90
, and can be used to assist in the rotational motion transfer from the motor or other motion imparting device to the mounting device
70
.
The motor or other motion imparting device
90
preferably provides rotational motion to the mounting device
70
, and thus to the holding device
50
and any paint roller brush
12
on the holding device
50
. A hand or power drill, screwdriver, or other such motor-driven device is suitable.
An illustrative use of the invention is shown in
FIGS. 1-6
. In use, a house, wall, ceiling or other structure or surface has been painted using a roller paint brush cover
12
, the roller paint brush cover
12
generally remains loaded with some paint. Rather than removing the loaded roller paint brush cover
12
from the handle framework
14
with the hands, gloves or other means that would then become soiled and/or ruined, the user of the invention grasps the handle
34
of the gripping device
30
and slides the cylindrical tube
32
portion of the gripping device
30
over the loaded roller paint brush cover
12
. Handle frameworks
14
typically have a singe shaped rod
16
extending from a handle
18
and terminating in a roller paint brush cover holding end
20
after bending through a series of curves
22
, thus holding the roller paint brush cover
12
from one end. A typical representation of a handle framework
14
is shown in FIG.
1
.
The griping device
30
is placed over the loaded roller paint brush cover
12
with the support rod
16
of the handle framework
14
passing through the slot
42
in the generally cylindrical tube
32
. The user pushes the gripping device
30
over the loaded roller paint brush cover
12
until the roller paint brush cover
12
presses against stopping device
44
or other stopping means. The user then continues to push the loaded roller paint brush cover
12
off of the handle framework
14
. If the gripping device
30
comprises a stopping device
44
, this will assist in pushing the roller paint brush cover
12
off of the handle framework
14
. Alternatively, the gripping device
30
can be structured to hold the roller paint brush cover
12
securely enough to remove the roller paint brush cover
12
from the handle framework
14
without the need for a closed or partially closed tail end
38
, or a stopping device
44
.
Once the loaded roller paint brush cover
12
is removed from the handle framework
14
, the user then transfers the loaded roller paint brush cover
12
onto the holding device
50
in generally the opposite manner as the roller paint brush cover
12
was removed from the handle framework
14
. The user slides the roller paint brush cover
12
onto the cage-like frame
52
or other structure of the holding device
50
and then removes the gripping device
30
by pulling it in the opposite direction, leaving the roller paint brush cover
12
on the holding device
50
. The holding device
50
either already is mounted on or then is mounted on the motor or motion imparting device
90
in much the same way a drill bit is mounted in the chuck of a power drill.
The loaded roller paint brush cover
12
then can be placed in an empty bucket and the motor or other motion imparting device
90
activated to spin the roller paint brush cover
12
. This optional first spin helps remove any extraneous paint from the roller paint brush cover prior to cleaning in the cleaning solution
96
. The roller paint brush cover then is placed into a bucket or other container
94
of water or soapy water (for water soluble paints) or other solvent (for water insoluble paints), generally referred to as a cleaning solution
96
, and the motor or other motion imparting device
90
activated. The roller paint brush cover
12
is spun around in the cleaning solution
96
for a period of time sufficient to remove the paint from the roller paint brush cover
12
. This step can be repeated any number of times to achieve the level of cleaning desired. The roller paint brush cover
12
then can be spun in a bucket of clean water to rinse cleaning solution
96
from the roller paint brush cover
12
. After the roller paint brush cover
12
has been cleaned, the roller paint brush cover
12
then can be spun in an empty bucket, cylinder or other structure, or in the open, to remove any excess water or cleaning solution
96
and to spin dry the roller paint brush cover
12
. The roller paint brush cover
12
now has been restored to a clean or cleaner state for reuse.
