Description
FIELD AND BACKGROUND OF THE INVENTION
[0001] The present invention is generally directed to painting
accessories, and more particularly to a brush with a variable
edge.
[0002] When painting, cleaning, or otherwise using a brush in other
applications, a user often encounters surfaces or areas that are
not flat or regular. In other words, a user frequently needs to
paint or clean surfaces that are irregular, raised, or otherwise
have different or challenging shapes. For instance, a surface maybe
angled or grooved, or have a convex or concave shape or contour. It
is desirable and important that a user be able to properly paint,
clean, or otherwise finish these types of surfaces.
[0003] Various prior art brushes are available in the prior art, as
shown in U.S. Pat. Nos. 843,222; 2,136,595; 2,329,534; 2,384,029;
2,816,305; 2,917,763; 3,668,850; 5,546,626; 5,592,711; and
6,202,248.

whose bristles are adjustable to provide multiple shapes for the
edge of the brush.
[0008] Another aspect of the present invention includes a brush
whose bristles can be adjusted to provide a substantially
continuous or uninterrupted edge the shape of which is
variable.
[0009] Another aspect of the present invention includes a brush
with a variable edge that includes a handle with proximal and
distal end portions, the distal end portion being of generally
hollow construction forming a base and including an end opening, a
bristle pack extending outwardly from the opening and including a
plurality of individual set of bristles of a predetermined width
that together form a continuous edge, and a slide mechanism for
adjusting the length of each individual set of bristles so as to
vary the shape of the edge.
[0010] Another aspect of the present invention includes a brush

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT(S) OF THE
INVENTION
[0034] As best shown in FIGS. 1-3, the brush B, in accordance with
a preferred embodiment of the present invention, includes a
proximal end portion in the form of an ergonomic handle 10, and a
distal end portion forming a base 12. The handle and base portions
10 and 12 are formed of wood, plastic, or other durable material
and can be molded or assembled.
[0035] As best shown in FIG. 3, the base 12 is of a generally
hollow construction defining a recess 14 for preferably removably
accommodating or anchoring a bristle pack BP. As described below in
more detail, the bristle pack BP includes individual sets of
bristles BR that are selectively extended out of or retracted
within the base 12, through an end opening 16, to form a
substantially continuous or uninterrupted edge E of a desirable
shape, without a significant or any gap therebetween (see FIGS.
3-4, 6 and 7-21). The edge E is substantially or completely linear
forming a generally straight sweep.
[0036] The bristle pack BP is preferably formed of multiple,
substantially similar bristle units 18, arranged on one side of a
plate 20 (see FIGS. 3-4 and 6). As best shown in FIG. 6, each
bristle unit 18 includes a set of bristles BR mounted in a slide
mechanism 22. The slide mechanism 22 includes a slider 24, which is
manipulated by a user to move the bristle unit 18 on the plate 20
to extend or retract the bristles BR within the base 12 (see FIGS.
3-4). In order to hold or secure the slider 24 at a desired
position on the plate 20, the slider 24 includes a locking tab 26,
to be received in one of the holes 28 of a corresponding
longitudinal array in the plate 20. The slider 24 may be formed or
molded as one integral piece with the slide mechanism 22, or as a
separate detachable component.
[0037] As best shown in FIG. 3, the bristle pack BP is anchored or
secured in the recess 14 by screws 30 and a face plate 32, in a
conventional manner. One skilled in the art would appreciate that
by detaching the face plate 32, any bristle unit 18 can be slid out
of the plate 20 through the end opening 16, for cleaning and/or
maintenance purposes. In this regard, it is noted that snap-on
fasteners may be used as a substitute for the screws 30, for the
ease and convenience of the user. Likewise, the face plate 32 can
be devised to operate in the same manner as the clamp cover 34
(described below), to function separately or integral therewith. It
is further noted herewith that other constructions may also be
devised to anchor or nestle the bristle pack BP into the recess 18.
For example, the bristle pack BP may be formed as a modular unit
that can be snapped into (or out of) the recess 18, thereby
dispensing with the need for the screws 30 and the face plate
32.
[0038] In order to immobilize the bristle units 18 in place,
particularly during use, a clamp cover 34 is attached to a side
wall 36, preferably by a hinge 38. The free end 40 of the clamp
cover 34 can be snapped under a hook 42 for locking the clamp cover
34 over the sliders 24. In this regard, it is noted herewith that
the height of the clamp cover 34 is selected such that at least a
portion of each slider 24 is caught under the clamp cover 34,
regardless of its position on the plate 20. In other words, whether
the sliders 24 are at the top-most position (FIG. 2), or at the
bottom-most position (FIG. 1), the clamp cover 34 would cover and,
therefore, clamp each slider 24, thereby securing the corresponding
bristle unit 18 in the selected place on the plate 20. As noted
above, the bristle pack BP includes individual bristle units 18
that are independently mounted and are movable up and down on the
plate 20. This construction allows a user to position the
individual sets of bristles BR at any desired location, so as to
form an edge having practically any shape, non-limiting examples of
which are illustrated in FIGS. 7-21.
[0039] It is noted herewith that by varying the width and total
number of bristle units 18, infinite size brushes can be
constructed.
[0040] It is further noted herewith that the smoothness of the edge
E would, at least partly, be dependent on the total number of
bristle units 18 and the closeness of the holes 28 in an array in
the plate 20. A larger number of bristle units 18, and the closer
the holes 28 are to one another in a particular array, the smoother
will be the edge E.
[0041] While this invention has been described as having preferred
sequences, ranges, steps, materials, structures, features,
components, or designs, it is understood that it is capable of
further modifications, uses and/or adaptations of the invention
following in general the principle of the invention, and including
such departures from the present disclosure as those come within
the known or customary practice in the art to which the invention
pertains, and as may be applied to the central features
hereinbefore set forth, and fall within the scope of the
invention.
