NOTCHED PAINT BRUSH
Abstract
A paint brush is attached to the rim of the mouth of a paint can
such that the brush bristles are vertically above the mouth and are
oriented at an angle between about 0 and about 90.degree. from the
vertical. A notch is formed on the side of the mid portion of the
brush between the handle and the bristles. The notch has an upper
face oriented toward the brush handle and a lower face oriented
toward the bristles. The upper face, the lower face and the space
there between are all dimensioned such that when the brush is
attached to the rim of the paint can, the rim bears against the
notch at a point adjacent to its upper face while the lower face of
the notch bears against the rim sufficiently to position the brush
at an angle from the vertical of less than about 90.degree..

CROSS-REFERENCE TO RELATED PRIOR APPLICATION
[0001] This application is a division of application Ser. No.
13/393,903 filed on Mar. 2, 2012 which is a 371 national stage
application of PCT/CA2010/001416 filed on Sep. 2, 2010 which claims
priority pursuant to 35 USC 119 to the benefit of priority of
Canadian application no. 2,677,618 filed on Sep. 4, 2009, the
entire contents of which are herein incorporated by reference in
their entirety.
FIELD OF THE INVENTION
[0002] This invention relates to paint brushes and more
particularly to a paint brush having a notch formed in its handle
or ferrule for hanging the paint brush to the rim of a conventional
paint can. The invention also particularly relates to a clip which
removably attaches to a paint brush and which has a notch for
hanging the paint brush to the rim of a paint can.
BACKGROUND OF THE INVENTION
[0003] In the interval of time between the period that a painter is
not using a paint brush, it is customary for him to place the brush
on the can which contains the paint. The painter does so because
the paint can is a handy place to place the brush at such times and
because the paint in the can is not discoloured by paint from the
brush which might dribble into it. The problem with using a paint
can for this purpose however is that paint can run from the can
onto a surface on which it rests. Furthermore, a brush can be too
easily knocked off a paint can by a painter's carelessness.
[0004] It is known to provide paint brushes with hangers or other
means to facilitate the attachment of the brush to a paint can.
Examples of such attachment means are described in U.S. Pat. No.
2,309,990 to Savi, U.S. Pat. No. 3,231,919 to MacDonald, U.S. Pat.
No. 4,887,327 to Meimeteas and U.S. Pat. No. 6,244,559 B1 to
Stanton. The attachment means described in these patents are
suitable for attaching a paint brush to a paint can so that the
brush does not easily fall off of the can but they do have a number
of shortcomings, one of which is that they project outwardly from
the paint brushes and can be a nuisance to painters when they are
painting in confined spaces. As well the projecting attachment
means are easily damaged and, once damaged, are not reliable for
attaching a paint brush to a can. A still further shortcoming of
some of the above mentioned attachment means is that the paint
brush is suspended outside the paint can where paint on the brush
can fall onto surfaces beside the paint can.
[0005] I have invented a paint brush and a clip for a paint brush
that have none of the short-comings mentioned above. Specifically,
the means by which the brush is attached to a paint can does not
project outwardly from the brush when the brush is in use and, as a
result, the attachment means does not interfere with the painter's
use of the brush. Furthermore the attachment means is not as
susceptible to breakage as are projecting attachment means such as
those mentioned above. In addition, my attachment means suspends a
paint brush over the mouth of a can of paint so that any paint that
falls from the brush falls into the can and not outside it.
SUMMARY OF THE INVENTION
[0006] Briefly, the paint brush of my invention is used use in
conjunction with a paint can having an upwardly opening mouth
defined by a continuous upwardly extending rim or perimeter having
upper and lower edges and, adjacent thereto and radially outwardly
of the mouth, a continuous upwardly opening groove. The paint brush
has a ferrule with front and back walls and a pair of side walls
which interconnect the front and back walls.
[0007] The ferrule has a notch which extends inward from one of the
side walls and which is defined by upper and lower faces. The upper
face has a generally horizontal central front edge and a pair of
upper lateral edges on opposite sides of the upper central edge.
Each lateral edge is formed in a separate front and back wall of
the ferrule and extends upward and away from the central edge. The
lower face has a generally horizontal lower central front edge and
is spaced apart from the upper central edge. The lower face further
has a pair of lower lateral edges formed in a separate front and
back wall of the ferrule and is on opposite sides of the lower
central edge.
[0008] Alternatively, where the paint brush lacks a ferrule, the
notch can be formed in the mid portion of the brush between the
bristles and the handle. The notch can have the same shape as the
notch formed in the ferrule described above.
[0009] As a further alternative, a notch of the same shape can be
formed in a clip which removably attaches to a paint brush. The
clip can be removed from the paint brush when the brush is in use
and attached when the brush is not in use.
[0010] The paint brush is adapted to hang from the rim of a paint
can such that the upper face of the notch rest upon the upper edge
of the rim while the lower face of the notch contacts the lower
edge of the rim. When the paint brush is hanging in this way, its
bristles are vertically above the mouth of the paint can.
[0011] In accordance with another aspect of the present invention,
the pain brush can be attached to the rim or perimeter portion of a
paint can opening such that the bristles of the brush are oriented
into the paint can at an angle of less than 90 degrees from the
vertical. The perimeter of the paint can has an upwardly extending
rim having upper and lower ends while the paint brush has a mid
portion connecting a handle to a set of bristles. A notch is
provided on a side of the mid portion between the handle and the
set of bristles for attaching the brush to the edge of the mouth of
the can. The notch is defined by an upper face oriented towards the
handle, a lower face oriented towards the set of bristles and an
opening separating the upper and lower faces. The opening, upper
face and lower face are all dimensioned such that when the brush is
attached to the perimeter of the paint can, the perimeter bears
against the notch at a point adjacent to the upper face while the
lower face bears against the perimeter sufficiently to position the
brush at an angle from vertical of less than 90 degrees.
[0012] In accordance with still further aspect of the invention,
the paint brush is used in conjunction with a paint can having an
opening circumscribed by an upwardly extending rim having upper and
lower ends. The paint brush includes a ferrule connecting a handle
to a set of bristles and a notch formed on a side of the ferrule
between the handle and the set of bristles. The notch is defined by
an upper face formed on the ferrule towards the handle, a lower
face formed on the ferrule towards the set of bristles, an opening
separating the upper and lower faces and a back face formed on the
ferrule and separated from the opening by a depth. The notch is
dimensioned to permit the paint brush to be hung from the rim of
the paint can by passing the upper end of the rim through the
opening. The opening, depth, upper face and lower face all being
dimensioned to hold the upper end of the rim within the notch while
the lower face of the ferrule bears against the rim at a point on
the rim between the upper and lower ends when the paint brush is
hung from the rim.
[0013] In accordance with a further aspect of the invention, the
paint brush is used in conjunction with a paint can having an
opening circumscribed by an upwardly extending rim having upper and
lower ends. The paint brush includes a ferrule connecting a handle
to a set of bristles and a notch formed on a side of the ferrule
between the handle and the set of bristles. The notch is defined by
an upper face formed on the ferrule towards the handle, a lower
face formed on the ferrule towards the set of bristles and an
opening separating the upper and lower faces. The notch is
dimensioned such as to permit the paint brush to be hung from the
rim of the paint can by passing the upper end of the rim through
the opening, the upper face being angled and dimensioned to hold
the upper end of the rim within the notch when the paint brush is
hung from the rim, the opening being dimensioned to position the
lower face of the notch at a point on the rim between the upper and
lower ends when the paint brush is hung from the rim.

DESCRIPTION OF PREFERRED EMBODIMENTS
[0023] With reference to FIGS. 1 and 3, the subject paint brush,
generally 10, is shown in conjunction with a conventional paint
can, generally 12. The paint can has a bottom wall, side walls
which extend upwardly and terminate at an upwardly opening mouth 14
defined by a continuous upwardly extending rim or perimeter 15.
Radially outwardly of the rim is a circular upwardly opening
groove, generally 16, defined by inner and outer lips 17, 18 and a
transverse portion 19 which defines the lower wall of the groove.
Outer lip 18 is radially inward of the outer wall 12a of the paint
can.
[0024] With reference to FIGS. 1, 2 and 4, the paint brush has a
ferrule 20 connecting a handle 22 and bristles 24. The ferrule has
oppositely facing front and back walls 26, 28 and a pair of
oppositely facing side walls 30, 32 which interconnect the front
and back walls. The side walls have a width which is short relative
to that of the front and back walls.
[0025] Instead of the set of bristles illustrated in the foregoing
drawings, the paint brush may provided with a foam pad for applying
paint.
[0026] In the foregoing respects, the paint brush is conventional.
However the paint brush differs from conventional brushes in the
provision of a notch generally 36, which extends inward from side
wall 30.
[0027] With reference to FIGS. 4 and 2, notch 36 is defined by
upper and lower faces 40, 42, respectively. When the longitudinal
axis 10a-10a of the brush is vertical, the upper face 40 has a
generally horizontal central edge or portion 40a which is formed in
the side wall of the ferrule and a pair of upwardly inclined
lateral edges or portion (one visible and numbered 40b in FIG. 3)
on opposite sides of the upper central portion. One upper edge 40b
is formed in front wall 26 of the ferrule while the other upper
lateral edge is formed in back wall 28. Each upper lateral edge
extends upwardly and away from the central portion.
[0028] The lower edge has a generally horizontal lower central
portion 42a which is formed in side wall 30 and spaced apart from
the upper central portion 40a. A pair of generally horizontal lower
lateral edges (one visible and numbered 42b) are formed in the
front and back walls of the ferrule and those lateral edges are
horizontal when the longitudinal axis of the brush is vertical.
[0029] It will be observed that the upper face 40 is inclined at an
oblique angle relative to the longitudinal axis 10a-10a of the
brush, preferably at an angle of about 45 degrees, while the lower
face 42 is inclined normal to the longitudinal axis.
[0030] With reference to FIGS. 1 and 3, the paint brush is adapted
to hang from rim 15 of the paint can when the upper lateral edges
40b of the notch rest upon rim 15 while the lower central portion
42a of the notch contacts the lower surface of transverse portion
19, The bristles, when the paint brush is so hanging, are disposed
within the mouth so that any paint that drops from the bristles
falls into the paint can.
[0031] The notch is dimensioned and configured to attach to the
mouth or perimeter of a paint can such that the brush is firmly
secured to the rim and is held such that its longitudinal axis is
disposed at an acute angle from the vertical, i.e. with the
bristles vertically above the interior of the paint can or, where
the bristles are within the can as illustrated in FIG. 1, above the
contents of the paint can.
[0032] With reference to FIG. 3A, the mouth or perimeter of the
paint can consists of an inner lip 134 and an outer lip 136. Inner
lip 134 forms an L-shaped section which extends radially inwardly
from outer lip 136. Transverse portion 138 extends between inner
lip 134 and outer lip 136. The top end 134a of the inner lip
defines the rim or perimeter of the mouth of the paint can while
the bottom end of the inner lip ends in an elbow 140 which is
integral with transverse portion 138.
[0033] The notch is configured such that its upper face 142 rests
upon top end 134a of the inner lip and extends between the inner
and outer lips while the lower face 144 of the notch abuts against
inner lip 134 at a point between its bottom end and transverse
portion 138. The point of contact between lower face 144 and inner
lip 134 is preferably at elbow 140 or between elbow 140 and top end
134a. With lower face 144 braced against inner lip 134 and upper
face 142 braced against top end 134a on the opposite side of inner
lip 134, the notch effectively locks onto the perimeter of the
paint can by virtue of the torque, indicated by arrow B, which is
applied to the brush by its weight. As a result, the brush is
prevented from accidentally dislodging from the perimeter of the
paint can because its inner lip 134 is effectively pinched between
upper the upper and lower faces of the notch.
[0034] The back face 150 of the notch is spaced from the entrance
152 of the notch by a depth which is selected to ensure that a
portion of inner lip 134 will fit inside the notch. If the notch is
too shallow, i.e. if the space between the entrance to the notch
152 and back face 150 is too short, then the notch may not secure
the paint brush to the perimeter very securely. Preferably, the
length of the entrance 152 measured parallel to the longitudinal
axis of the paint brush is 1/8th inch. Preferably also, back face
150 is about 3/16 of an inch from the entrance.
[0035] A subtle modification of the relative dimensions of lower
face 144, upper face 142 and the depth of the notch can be made
while not departing from how the notch secures the brush to the rim
of a paint can. For example. FIG. 6 shows an alternate embodiment
of the present invention showing a paint brush 160 having a notch
162 with the lower face 166 and upper face 164 and back face 168
and an entrance 170 to the notch between faces 164 and 166. In this
embodiment, entrance 170 is dimensioned such that inner lip 172
fits into the inside of the notch. The lower face 166 of the notch
is dimensioned and configured such that the face bears against
elbow 174 while the top end 172a of the inner lip is held against
upper face 164. As in the previous embodiment, the inner lip 172 is
pinched between lower and upper faces 166, 164 and the torque
acting on brush 160 (indicated by arrow C) being sufficient so that
the pinching action is strong enough to lock the brush onto the
perimeter.
[0036] As can be seen from FIG. 7, the notch can be made
sufficiently large that the notch couples the brush to the
perimeter of the paint can in the same manner as in the previous
two embodiments by spaning the entire perimeter. In this embodiment
brush 251 has a mid portion 249 with a notch 244 formed therein.
Notch 244 has an upper face 246, a lower face 245 (with a outer
corner 248) an entrance or opening 252 and a back face 250.
Entrance 252 is sufficiently large that it can span between outer
lip 242 and inner lip 234 of the perimeter. The depth of notch 244
i.e. the space separating entrance 252 from back face 250, is
sufficiently large to permit a portion of inner lip 234 to fit
within the notch. Upper face 246 and lower face 245 are also
dimensioned so that outer lip 242 bears against upper face 246 and
lower face 245 bears against inner lip 234. As in the previous
embodiments, the force of gravity acting on the brush creates a
torque, illustrated by arrow D, which causes notch 244 to pinch the
perimeter between upper face 246 and lower face 245 thereby
securing the brush tightly to the perimeter of the paint can.
[0037] An alternate embodiment of the present invention is shown in
FIG. 5 and includes a standard paint brush, generally 270 having a
handle 272, bristles 274 and a mid portion 276. Attached to mid
portion is a clip 280 having a notch 282 formed thereon. The notch
may be the same as any of the notches described above, the only
difference being that instead of being formed on the mid portion
itself, the notch is formed on clip 280. The clip may be made of
injection moulded plastic or aluminum and is secured to mid portion
276 by means known generally in the art such as by adhesive or by
fasteners. Alternatively the clip may be made of resiliently
deformable material such as spring steel or resiliently deformable
plastic and is biased against the front and back faces of the
ferrule by the inward pressure from the two ears 284. When the clip
is secured to the brush in the illustrated manner, the brush can be
mounted in a paint can as in the previously describe
embodiments.
[0038] A further embodiment of the present invention is shown in
FIG. 8 and includes a standard paint brush having a handle portion
with a mid portion 300 having notch 310 which is defined by upper
face 312, back face 314 and lower face 316. Lower face 316 is
contoured to closely match the curve of transverse portion 338 of
the groove at the mouth of the paint can so as to hold inner lip
340 of the paint can firmly between upper and lower faces 312, 316
of the notch in contact with the inner lip.
[0039] The present invention permits the paint brush to be securely
attached to the inner lip of the paint can so that the paint brush
does not accidentally become dislodged. The brush is not simply
hanging onto the inner lip, rather the faces'of the notch
effectively pinch the inner lip such that the force of gravity
acting on the bristle portion of the brush is sufficient to
effectively lock the paint brush in place. The pinching action of
the lower face of the notch on the inner lip of the paint can is
sufficiently strong that when the paint brush is mounted to the
paint can as shown in FIG. 1, if the paint brush is lifted, the can
is lifted as well.
[0040] A paint brush made in accordance with the present invention
has several advantages. First, simply mounting the brush on the
inner lip of the paint can is sufficient to cause the excess paint
on the brush to simply drip off the brush and into the can. Also,
the paint brush can be stored temporarily on the paint can when the
user needs to put down the paint brush in order to do something
else. The user can simply unhook the paint brush from the can in
order to start painting again. Also, while the paint brush can be
mounted to the inner lip of a paint can as discussed above, the
same brush can also be hung in a similar fashion to a rack or other
mount. For example, a paint brush rack can be made having an
elongated U shaped trough having a similar structure as the inner
lip or rim of a paint can. If this U-shaped trough is dimensioned
in the same way as the rim of a paint can, then one or more brushes
can be mounted to the rack as if the rack is one large paint
can.
[0041] In the foregoing description, the notch is sometimes
described as being formed in a ferrule and sometimes formed in the
mid section of a brush which lacks a ferrule. For purposes of the
present invention, it does not matter whether the notch is formed
in a ferrule or in the mid section of a brush which lacks a
ferrule. The notch is equally effective whether formed on either
one. As well, while bristles are frequently referred to in the
description, for purposes of the present invention, it does not
matter whether the brush has bristles or has a foam pad since the
