Description
The invention pertains to a two-sided handle brush, that is, one
which is provided with brush elements on both sides.
Handle brushes having a fixed handle and being provided with brush
members on one side are generally known. There are also known
two-sided brushes having brush elements on both sides, in which the
bristles, for example, are firmly embedded in a bristle support
element. With the known two-sided embodiment of a crepe rubber
brush body, there are provided slits in a stationary brush body,
rolled or folded crepe rubber strips being mounted in such
slits.
It is an object of this invention to provide a handle brush the
brush body of which is two-sided, and which consists of two disc
members, which preferably are provided with an elastic textile-like
brush element.
It is a further object of this invention to provide a two-sided
handle brush which is characterized by a frame which is fixedly
connected with the handle, and which two support plates are formed
as brush bodies back-to-back and are firmly embedded in the frame.
The opposite surfaces of the brush elements are provided with brush
materials.
The brush materials on both of the opposite sides of the brush body
can thereby be provided with identical or different known materials
suitable for brushing purposes.
The invention is illustrated in conjunction with drawings in which
one embodiment of the invention is illustrated in detail.
In the drawings:
FIG. 1 is a side view of a two-sided handle brush;
FIG. 2 is a plan view of the handle brush in which no brush body
has been mounted;
FIG. 3 is a sectional view along line 3--3 of FIG. 2;
FIG. 4 is a front view of the handle brush in the direction of the
arrow in FIG. 1; and
FIG. 5 is an enlarged partial view of the portion of FIG. 3
designated with the circle B.
The illustrated handle brush consists, for example, of plastic
material and is made of two identical half-discs or cups. The brush
can also be manufactured of a correspondingly suitable additional
material which can be handled and processed in a manner similar to
textile material.
On the handle 1, which is preferably made of one piece, there is
formed a frame 2. In the illustrated embodiment, the frame 2 is
slightly trapezoidally-shaped, but can also be rectangular,
triangular, multiangular, round, or oval. In the frame there is
mounted on both sides a brush element which is covered with brush
material 3, 3', in such a manner that the brush elements, for
example, bristles, extend away from each other, that is,
practically offset with respect to each other by 180.degree..
A brush consisting of plastic or also metal and having a handle can
be constructed as is illustrated in the drawings. In this
embodiment, the short bristles are provided as brush elements, and
are mounted in a flat brush support, such as, for example, a woven
material. As already mentioned, the brush bodies can be provided
with any type of flexible brush material.
The illustrated example consists of two identical plastic half-cups
1a, 2a and 1b, 2b, which are secured to each other in a simple
manner. By means of such half-cups one obtains considerable
technical advantages.
As can be noted from FIG. 3, a sleeve 4 extends towards the
interior at the vicinity of the handle end of the half-cup 1a. Into
this sleeve 4 there extends from the other half-cup 1b towards the
interior a pin 5 which is tightly fitted with respect to the sleeve
4. The sleeve 4 and pin 5 serve simultaneously as spacer elements
for increasing the stiffness of the grip 1. The peripheral flange 6
bent around the entire periphery of the half-cup 1a of the grip is,
at its end surface, provided with a pin 6' which extends into a
corresponding recess 7' in the first end surface of the directed
end surface of the periphery of the bent border flange 7 of the
second half-cup of the grip. The pin 6' and recess 7' are so
dimensioned that the pin 6' fits tightly into the recess 7'. Such
pins in one of the half-cups which fit into recesses in the other
half-cups are quite advantageous and consequently a large number of
them may be provided.
As can be noted from FIG. 3, there is furthermore provided at the
forward end of the frame 2 in the half-cup portion 2a and 2b, a pin
8 and a recess 9 which interfit with each other. Advantageously
there may be provided a large number of such pins and recesses in
the opposite surfaces and the arrangement thereof may be
alternated. In the sectional view according to FIG. 3, both of the
brush elements which are provided with brush materials 3 and 3' are
shown without support or base plates. A portion of the base plate
11 is illustrated in the partial view of FIG. 5.
The flat brush materials 3 and 3' are mounted with their base
plates 11, 11 back-to-back in the frame 2 and are maintained
securely by means of teeth 10. These teeth are disposed along the
periphery and bear against the brush material (3, 3'), in
particular the portion that corresponds to the frame half-cups 2a,
respectively 2b, directed upwardly, respectively downwardly, that
means always directed towards the brush interior. In order for
these teeth to bear against a resisting surface and in order to
plant firmly the border portion of the brush material 3, 3' therein
arranged, there is provided for each brush material 3, 3' a base
plate 11 forming the brush body, at the exterior surfaces of which
the flat brush material can be pulled on. This base plate is along
its entire periphery bent upwardly, so that it assumes the shape of
a flat cup. Its upper edge is again bent outwardly and forms a
horizontal projecting portion or collar 12, which extends along the
entire periphery of the base plate 11 and engages via the teeth 10
the periphery of the frame portion 2.
In order to provide for the flat, bendable brush means provided
with bristles or other equivalent elements a frame support there
are provided at the exterior periphery of the projecting element or
collar 12 of the base plate 11 a number of teeth 13, which are
shown to be directed downwardly in FIG. 5. The circumference of
these teeth is at all times directed in the direction of the upper
surface of the base plate 11. The flat, bendable brush means is
then disposed between the upwardly directed portion of the base
plate 11 and the edge of the frame portions 2a, respectively 2b,
which project against this portion of the base plate 11 and is
thusly guided in a somewhat S-shape around the points of the teeth
10 and 13. In this manner the brush means 3, 3' provided with
bristles is firmly and tightly held in position.
The base plates 11, which are of identical construction, have a
plurality of spacer posts 14 distributed over their surfaces, as
shown in FIGS. 2 and 3. Opposite posts 14 are aligned with each
other, their inner ends abutting along the central longitudinal
plane of the brush. By means of the spacer members 14 the stiffness
of the brush is increased.
Such a construction of the individual brush members makes it
possible to construct a two-sided brush in a very simple manner.
Each frame portion is first mounted in one way, and then the brush
means and finally the brush plate is mounted thereon. Then both of
the shaped members or shaped halves are clamped together and thus
the individual brush portions are firmly connected by engaging into
each other, that is, by having the complementary engaging and
clamping members engage, respectively, clamp to each other. This
new type of handle brush is suitable, in particular for brush
elements consisting of bristles, which are mounted in a flat,
bendable brush means in an oblique position and in which all of the
bristles are inclined in one direction. One can deal herewith with
a relatively long or short bristle. With such brushes having
inclined bristles, one must take care that during the brushing
operation the points of the bristles are directed in a direction
opposite to the brushing movement so that the dirt particles to be
removed can be grasped by the bristles and moved into the
intermediate bristle spaces. When the brush is moved in the
opposite direction, the retained dirt particles are again released
and fall out of the intermediate spaces. Since, however, the brush,
during the brush operation, is frequently changed from one hand to
the other, it is particularly difficult with handle brushes, to
maintain at all times the correct brushing stroke. With a two-sided
brush the exchange from one hand to the other can be carried out in
an extremely simple manner, since the handle is only turned
180.degree. around its longitudinal axis in order to adjust the
bristle points along the most comfortable brushing stroke
direction. In such a case, the opposite back-to-back arranged brush
bodies with the brushing means therein affixed are mounted in the
frame in such a way that their obliquely extending bristle points
are inclined in the same direction. The bristle points may, in the
opposite brushing means, be directed in the opposite direction. An
arrow on the frame or on the handle indicates at all times the
brushing direction, that is, the inclination of the bristles. The
flat brushing means is advantageously cushioned in a known
manner.
In lieu of the inclined bristles being mounted on the flat,
bendable support means, respectively brushing means, there can also
be mounted other brushing elements, as for example, velvet, plush
or similar material. If this is done, then the brush can, for
example, also be used for polishing shoes, whereby due to the
different colors of the brushing elements, such as for example,
light and dark, brown, black, etc., at all times the side for the
shoe color to be brushed can be noted. Obviously also normal
brushing bristles can be used and furthermore, for example, one of
the sides of the brush may have coarse bristles and the other side
fine bristles thereby being adapted for coarse and fine brushing
operations respectively.
Although the invention is illustrated and described with reference
to a preferred embodiment thereof, it is to be expressly understood
that it is in no way limited to the disclosure of such an
embodiment, but is capable of numerous modifications within the
scope of the appended claims.
