Description
Numerous types of cleaning instruments and brushes are known in the
prior art as operable to clean uniformly spaced objects, such as
venetian blinds, combs, grills, etc. Nevertheless, the same prior
art devices when fitted with brushes or brush-like cleaning
elements, are not easily cleaned themselves nor the brush portion
of the cleaning device easily replaced when worn out as may be
necessary. Other prior art multiple element brushes have the
elements thereof individually removably mounted with a handle.
However, these devices have a practical disadvantage in that
usually the elements will wear out all at once; thus individual
replacability is virtually useless.
In one preferred specific embodiment of this invention, a brush
structure includes a plurality of elongated cleaning elements each
with an individual shank portion connected to a main shank portion
which is mountable in a handle. The cleaning elements are
preferably elongated cylindrical bristle brushes arranged in a
trifurcated configuration relative to the main shank and handle.
The bristles of the brushes are preferably intermeshed on their
adjoining peripheral portions and arranged in a substantially
parallel relation relative to one another. The main shank of the
brushes can be removably mountable with the handle or it can be
permanently mounted with the handle.
One object of this invention is to provide a brush structure
overcoming the aforementioned disadvantages of the prior art
devices.
Still, one other object of this invention is to provide a brush
structure having a trifurcated brush assembly removably mountable
with a handle.
Still another object of this invention is to provide a brush
structure having elongated and trifurcated brush elements
permanently mounted in a handle.
Yet, an additional object of this invention is to provide a brush
structure with three cleaning elements which is adapted for the
cleaning of an object simultaneously on two sides of the object as
the object is moved between the elongated brush elements.
Various other objects, advantages, and features of the invention
will become apparent to those skilled in the art from the following
discussion, taken in conjunction with the accompanying drawings, in
which:
FIG. 1 is an elevation view of the wide side of the brush structure
with the main shank passageway shown therein in dashed lines;
FIG. 2 is an elevation view of the narrow side of the brush
structure with the brush assembly permanently mounted in the handle
assembly;
FIG. 3 is a bristle end view of the brush assembly showing the
intermeshing bristles; and
FIG. 4 is an enlarged elevation view partially in cross-section of
a portion of the removable brush assembly brush structure showing
the main shank portion of the brush assembly and attaching portion
of the handle.
The following is a discussion and description of preferred specific
embodiments of the brush structure of this invention, such being
made with reference to the drawings, whereupon the same reference
numerals are used to indicate the same or similar parts and/or
structure. It is to be understood that such discussion and
description is not to unduly limit the scope of the invention.
Referring to the drawing in detail and in particular to FIG. 1, a
brush structure of this invention, is shown therein and generally
indicated at 10. The brush structure 10 includes a plurality of
brushes comprising a brush assembly 12 mounted with a handle 14
which are connected by a main shank 16. The brush structures are
shown in FIGS. 1 and 4 with the main shank portion 16 removably
mountable in the handle 14, and shown in FIG. 2 with the main shank
portion 16 permanently mounted in the handle 14.
The brush assembly 12 preferably includes three elongated cleaning
elements or brushes indicated at 18, 20 and 22. Each of the
individual brushes 18, 20 and 22 have individual shank portions
respectively indicated at 24, 26 and 28. The shank portions of the
outer brushes 24 and 28 are turned inwardly toward the center shank
member 26 to achieve the trifurcated support configuration. The
specific and preferred arrangement of the brushes 18, 20 and 22 is
with their elongated axes oriented parallel, in a single plane, and
spaced sufficiently close together so that the adjacent end
portions of the bristles will intermesh. FIG. 3 is an end view of
the unattached end of the brush assembly 12 showing the intermeshed
and spaced relationship of the cleaning elements 18, 20 and 22. In
the spaced relationship of the cleaning elements it is to be noted
that only the adjoining end portions of the brush bristles are in
contact as is indicated at 30 and 32.
The preferred construction of the brush assembly incorporates the
use of individual brush members which are constructed of bristles
mounted in a twisted wire frame. The specific brush bristles used
in the construction of the brush structure 10 of this invention
will depend upon the intended use of it. Obviously in some
applications of the brush structure 10, the use will require hair
bristles and in others flax bristles and in still others bristles
of an inert material may be necessary. The twisted wire frames of
the individual bristles 18, 20 and 22 are indicated respectively at
34, 36 and 38 in FIG. 2; they extend the length of the bristle
portion of the brush and extend therefrom forming the shank
portions 24, 26 and 28. As can be seen in FIG. 4 the three
individual shanks 24, 26 and 28 are twisted together into a main
twisted shank indicated at 40. In one preferred specific embodiment
of this invention, as shown in FIG. 2, the main twisted shank 40 is
directly mounted permanently in the handle 14 by the use of an
adhesive or the like to secure it in a passageway formed in the
handle. In another preferred specific embodiment of this invention,
as is shown in FIG. 4, the main twisted shank 40 is imbedded in a
fixture which is removably mountable in a passageway formed in the
handle 14.
In the permanently mounted configuration of the brush assembly 12
with the handle 14, the twisted shank 40 is simply inserted in a
passageway 41 at one end of a handle as illustrated in FIG. 2. In
this permanently mounted brush structure the twisted shank 40 is
held in place in the handle by an adhesive material or some other
material so that the main shank 40 is permanently and rigidly fixed
in the handle 14. In the removably mountable configuration of the
brush structure 10, the twisted shank 40 is secured in a mounting
fixture 42 as is shown in FIG. 4. The end portion of the handle as
shown in FIG. 4 has a passageway therein indicated at 44 in which a
mounted fixture 46 is secured. The mounted fixture 46 is adapted to
engage with and retain the mounting fixture 42. As can be seen in
FIG. 4 the mounting fixture 42 and mounted fixture 46 are provided
with cooperating threaded surfaces which enable the main shank
portion 16 to be threadably engaged with the handle 14. A locking
washer 48 is provided to fit around the mounting fixture 42 so as
to retain the main shank 16 in a fixed relation to the handle 14
when the mounting fixture 42 is drawn up into the mounted fixture
46. In the drawn up position a flange 50 on the mounting fixture is
closely adjacent to a flange 52 on the mounted fixture and the lock
washer 48 is positioned therebetween, holding them in a locked
relation.
It is to be noted that other cooperatively engagable configurations
of the mounting fixture and mounted fixture other than the threaded
configuration shown in the drawings will function in a similar
manner to hold the shank portion 16 and handle portion 14 in the
engagable removable relation. Such other configurations which will
function similarly to the threaded configuration shown herein
include cylindrical and polygon shaped fixtures having means to
cooperatively engage with one another and lock with one another in
a rigid position. Other configurations of the mounting fixtures can
be such as would include magnetic, adhesive or compressive
components adapted to attach the brush assembly 12 and handle 14 in
a substantially rigid relation.
The handle 14 of the brush structure of this invention is provided
with means to attach the brush assembly 12 on one end thereof and
means to grasp the handle by hand on the remaining portion thereof.
The simple handle 14 as shown in the drawings is provided with
indentations on its brush end portion and a straight grasping
portion 56 on its remaining portion. The indentations 54 in
practice have been found helpful to provide support for a person's
thumb and forefinger when grasping the handle 14 during its use.
The handle 14 shown in the drawings is shown to illustrate one type
of handle which can be used with the brush structure 10 of this
invention. It is to be noted that other styles and shapes and
designs of handles can be used to replace the handle 14 shown in
the drawings. Other handles usable with the brush structure of this
invention can include handles specifically designed to be gripped
either by the right or left hand or handles designed so as to be
attachable to an extension member, and other handles designed with
shields and so forth on the brush end portion thereof.
In the manufacture of the brush structure 10 of this invention, it
is obvious that the brush assembly 12 can easily be constructed of
conventional brush materials and by conventional brush
manufacturing techniques so as to achieve the end product.
Likewise, it is obvious that the handle 14 can be constructed
simply as shown in the drawings in order to achieve the end product
of the brush structure. The brush assembly 12 can be constructed so
as to have the individul cleaning elements 18, 20 and 22 of
different densities of bristles, and same can be constructed with
brisles of different materials. The handle 14 obviously can be
easily constructed and attached to the brush assembly 12 in a
permanently mounted configuration and can also be easily
constructed in a removably mountable configuration.
In the use and operation of the brush structure 10 of this
invention, it is seen that same provides a trifurcated brush
structure having elongated and parallel cleaning elements which are
adapted to pass over, alongside and between objects for the
cleaning thereof and same is provided with a handle. The brush
structure of this invention, due to its trifurcated and parallel
brush assembly, is particularly adapted to use for the cleaning of
grill structure, such as oven grills, fireplace grills, barbecue
grills, and the like, where the cleaning elements can be passed
alongside and between the structural grill members. Also, due to
the specific construction of the brush assembly, it is also
particularly well adapted for use in cleaning any object wherein
two sides of the object are to be cleaned and can be passed between
the cleaning elements, such as decorative scrolls, table legs, and
the like. In the use of the brush structure of this invention, it
is obvious that same provides a brush structure wherein the brush
assembly portion thereof is removable from the handle, so that the
handle portion of the structure can be re-used once the brush
assembly is no longer usable and must be discarded. In the
permanently mounted configuration of the brush structure, it is
obvious that the brush assembly can be used in the same manner to
clean objects as the removably mounted configuration and the brush
completely discarded when desired.
As will become apparent from the foregoing description of the
applicant's brush structure, relatively inexpensive means have been
provided to accomplish the herein described brush structure. The
brush structure is economical to manufacture, simple to use,
attractive in appearance, and can be provided with a re-usable
brush assembly mountable with the handle or can be provided as a
complete permanently connected brush and handle.
While the invention has been described in conjunction with the
preferred specific embodiments thereof, it will be understood that
this description is intended to illustrate and not to limit the
scope of the invention, which is defined by the following
claims.
