Parent Case Text
BACKGROUND OF THE INVENTION
The present invention is a continuation-in-part of my co-pending
application Ser. No. 162,343 filed July 14, l971, for "Brush", now
U.S. Pat. No. 3,744,078.
Claims
What is claimed as new and desired to be protected by Letters
Patent is set forth in the appended claims:
1. A nail brush, comprising a backing member having a surface, a
longitudinal and a transverse direction; and a plurality of slender
bristles of different lengths projecting from said surface and
having free tips which together define a cleaning face having a
plurality of transversely extending depressions, a central
longitudinally extending depression having a bottom wall, and a
central longitudinally extending recess in said bottom wall.
2. A nail brush as defined in claim 1, wherein said bristles are of
synthetic plastic material.
3. A nail brush as defined in claim 2, wherein said backing member
is also of synthetic plastic material and of one piece with said
bristles.
4. A nail brush as defined in claim 1, wherein said longitudinally
extending depression and said longitudinally extending recess are
each of substantially right-angular cross-sectional contour.
5. A nail brush as defined in claim 1, wherein said transversely
extending depressions are of substantially arcuate cross-sectional
contour.
6. A nail brush as defined in claim 1, wherein said backing member
is provided with a plurality of holes.
7. A nail brush as defined in claim 6, wherein said holes are
slot-shaped.
Description
This invention relates to a brush, more particularly to a nail
brush for cleaning the nails on the human extremities.
In my co-pending application mentioned above I have disclosed a
brush which is particularly suitable as a nail brush and in which a
backing member is provided on a surface thereof with a plurality of
slender bristles of different lengths which project from this
surface and which have free tips together defining a cleaning face.
According to my disclosure this cleaning face has a plurality of
transversely extending depressions and a central longitudinally
extending depression. The purpose of having the longitudinally
extending depression is to permit a simpler and more effecting
cleaning of the fingernails, because the tip of each finger can be
inserted into this depression and will be brushed when relative
movement of the finger and backing member is effected, whereas
opposite sides (top and bottom) of the fingertip will be cleaned by
the bristles located at opposite sides of and bounding the central
longitudinally extending depression.
It has been observed, however, that there are instances where
further improvements are desirable.
SUMMARY OF THE INVENTION
It is, accordingly, a general object of the present invention to
provide such further improvements.
More particularly it is an object of the invention to provide an
improved nail brush which affored such improvements.
Another object of the invention is to provide such an improved nail
brush which is simple to manufacture and therefore inexpensive to
sell, and which is highly effective in its intended purpose.
In keeping with these objects, and with others which will become
apparent hereafter, one feature of the invention resides, briefly
stated, in a nail brush which comprises a backing member having a
surface, a longitudinal and a transverse direction, and a plurality
of slender bristles of different lengths which project from this
surface and have free tips together defining a cleaning face.
According to the invention the cleaning face has a plurality of
transversely extending depressions, a central longitudinally
extending depression having a bottom wall, and a central
longitudinally extending recess provided in this bottom wall.
The present invention as thus briefly outlined above achieves its
intended purpose. By inserting the tip of a finger into the central
longitudinally extending depression, the tip and the two sides of
the finger are cleaned as before, that is as with the brush
disclosed in my aforementioned co-pending application.
However, in many instances a user will have long fingernails,
especially ladies who tend to quite frequently have long or even
very long fingernails. These are not properly cleaned in the nail
brushes according to the prior art, but due to the fact that they
can now extend into the central longitudinally extending recess
which is formed in the bottom wall or bottom surface of the central
longitudinally extending depression provided in the cleaning face
of my novel nail brush, the fingernails can extend into this
central longitudinally extending recess and will be cleaned;
especially, they will be cleaned underneath the nail because the
bristles will enter into the space between the surface of the
finger and the nail and will provide the intended cleaning
function.
Thus, the nail brush according to the present invention achieves it
intended purpose, in that it provides an improvement over what is
known from the art.
The novel features which are considered as characteristic for the
invention are set forth in particular in the appended claims. The
invention itself, however, both as to its construction and its
method of operation, together with additional objects and
advantages thereof, will be best understood from the following
description of specific embodiments when read in connection with
the accompanying drawings.
BRIEF DESCRIPTION OF THE DRAWINGS
The single FIGURE is a perspective view illustrating the novel nail
brush according to the present invention.
DESCRIPTION OF THE PREFERRED EMBODIMENTS
Discussing the drawing in detail it will be seen that reference
numeral 1 identifies my novel nail brush in toto, and reference
numeral 2 identifies the backing member of the nail brush. The
backing member is elongated, having a longitudinal and a transverse
direction, and on one of its surfaces there is provided a plurality
of slender bristles 3 of different lengths. The bristles may be of
synthetic plastic material, for instance nylon or the like, and the
same is true of the backing member 2. In fact, it is advantageous
from a point of view of manufactureing simplicity, and thus from a
point of view of selling economy, if the backing member and the
bristles are of one piece with one another.
The bristles have free tips which, as the drawing clearly shows,
together define a cleaning face. According to the invention, and
due to the different lengths of the various bristles, this cleaning
face is provided with a plurality of transverse recesses 4, that is
recesses which are adjacent one another in the longitudinal
direction of the backing member 2 and which extend in the
transverse direction thereof. These recesses serve the same purpose
as the similar transverse recesses disclosed in my aforementioned
co-pending application and are of substantially arcuate
cross-sectional contour. The cleaning face is in addition provided
with a longitudinally extending recess 5, being located centrally
intermediate the lateral edges of the cleaning face and having a
bottom wall or bottom surface bounding it. In this bottom wall or
bottom surface there is provided, again centrally located, a
longitudinally extending depression 6 which, of course, is also
formed due to the fact that the various bristles are of different
lengths as the drawing shows. When a fingertip is inserted into the
recess 5 the fingernails will extend into the depression 6 and
relative movement of nail brush and fingertip in the longitudinal
direction of the backing member 2, will effect cleaning of the
surfaces of the fingertip as well as cleaning underneath the nail
of the finger.
Advantageously the backing member 2 will be provided with a
plurality of holes 7 which are shown in broken lines and which may
have various different configurations, including the slot-shaped
configuration which has been illustrated. This makes it possible
for water employed in the cleaning of fingertips and fingernails,
to run out, carrying away any dirt that has been removed.
Naturally, it would be possible to configurate my novel nail brush
in a manner other than what has been illustrated, and in fact any
configuration suitable is intended to be encompassed within the
concept of my invention and within the claims which are appended
hereto, as long as the provision of a central recess in the bottom
wall or bottom surface of the central depression is assured.
It will be understood that each of the elements described above, or
two or more together, may also find a useful application in other
types of constructions differing from the types described
above.
While the invention has been illustrated and described as embodied
in a nail brush, it is not intended to be limited to the details
shown, since various modifications and structural changes may be
made without departing in any way from the spirit of the present
invention.
Without further analysis, the foregoing will so fully reveal the
gist of the present invention that others can by applying current
knowledge readily adapt it for various applications without
omitting features that, from the standpoint of prior art fairly
constitute essential characteristics of the generic or specific
aspects of this invention and, therefore, such adaptations should
and are intended to be comprehended within the meaning and range of
equivalence of the following claims.
