Abstract
A backscrubber assembly adapted to hold a washing element with a cord. The backscrubber assembly comprises a handle, and a bowl permanently attached to the handle, the bowl being sized and shaped to cradle the removable washing element. The backscrubber uses the cord to attach and detach the washing element. When attached, the cord holds the washing element firmly in the bowl. When the cord is detached, the washing element is separate and free from the backscrubber assembly. In one embodiment, the backscrubber assembly has a slit in the bowl. The slit has a first pressure point and a second pressure point. The first pressure point and the second pressure point are directed towards each other so that when the cord of the washing element in placed in the slit, the first and second pressure points squeeze the cord between them, thus securing the cord by friction.
Description
BACKGROUND
1. Field of the Invention
This invention relates to a backscrubber with a removable washing element.
2. State of the Art
Because it is awkward to reach one's own back, many people use backscrubbers to lather their backs while bathing or showering. Most of these backscrubbers consist of a sponge attached to a handle. However, within the last few years, nylon mesh scrubbers have become increasingly popular. Nylon mesh scrubbers, sometimes called scrubbies or nylon mesh puffs, are made of a nylon mesh secured by a cord to form a ball or puff. Since they readily absorb soap and other skin cleaners, many people use nylon mesh scrubbers for lathering. Thus, some people have both a backscrubber and a nylon mesh scrubber in their already crowded bathtubs or shower stalls. There is a need for a backscrubber that can use the same nylon mesh scrubber one uses to lather the rest of the body.
SUMMARY OF THE INVENTION
It is an object of the invention to provide a backscrubber assembly to hold a nylon mesh scrubber.
It is also an object of the invention to provide a backscrubber assembly that allows a person to use the same nylon mesh scrubber as a backscrubber and for lathering other parts of the body.
It is an additional object of the invention to provide a backscrubber assembly that is easy to manufacture.
It is a further object of the invention to provide a backscrubber assembly that is easy to use.
It is another object of the invention to provide a backscrubber assembly that can be used with an off-the-shelf nylon mesh scrubber.
These above objects are realized through a backscrubber assembly to hold a removable washing element such as a nylon mesh scrubber. The removable washing element includes a cord. The backscrubber assembly has a handle and a bowl permanently attached to a handle. The bowl is sized and shaped to cradle the washing element. The backscrubber assembly also includes means for attaching and detaching the cord. When the cord is attached, the washing element is held firmly in the bowl. This allows a person to hold the handle and wipe the washing element against that person's back without the washing element slipping. When the cord is detached, the washing element is separate and free from the backscrubber assembly.
In one embodiment, the backscrubber assembly has a slit in the bowl. The slit has a first pressure point and a second pressure point. The first pressure point and the second pressure point are directed towards each other so that when the cord of the washing element in placed in the slit, the first and second pressure points squeeze the cord between them, securing the cord by friction. The first and second pressure points of the slit may be off set in relation to each other. There may also be a means to kink the cord at a generally right angle to the direction that the cord goes through the slit to further secure the cord.

DETAILED DESCRIPTION
As shown in
FIG. 1
, a backscrubber assembly
13
holds a removable washing element
11
. In one embodiment, the removable washing element is a scrubber of nylon mesh material, held in generally in a ball or puff by a cord
15
. Such scrubbers are well known in the art and are readily available to users. The backscrubber assembly include a handle
17
permanently fused to a bowl
19
. The bowl is sized and shaped to cradle the removable washing element. The handle is about a foot long, a comfortable length for the consumer to use while scrubbing a back. A hanging string
171
or other means to hang the backscrubber may be on the handle. A vertical slit
14
pinches the cord
15
to hold it in place. The width of the vertical slit
141
is slightly smaller than the diameter D of the cord. There must be enough flex in the vertical slit to allow give as the cord is pulled threw the slit, yet the vertical slit must be firm enough to hold the cord in place. The backscrubber assembly is made of hard but flexible plastic.
FIG. 2
a
and
FIG. 2
b
shows details of the bowl
19
of the backscrubber assembly.
FIG. 2
b
is a cut away view of the backscrubber assembly along the
2
b—
2
b
plane of
FIG. 2
a.
As shown in
FIG. 2
a,
the bowl is generally round. As shown in
FIG. 2
b,
the surface of the bowl
23
is generally concave to cradle the removable washing element. Cut-outs
25
decrease the weight of the bowl. A V shaped cut
27
helps the user guide the cord into the vertical slit
14
. Because the bowl has to be firm to support the removable washing element, the bowl may lack the flexibility required for the vertical slit. Thus, a portion of the bowl is shaved away to form a thin blade
29
along one edge of the vertical slit. As shown in
FIG. 2
b,
the width of the blade
229
is thinner than the width of bowl
231
. A horizontal slit
291
separates a portion of the blade from the bowl to increase the flexibility of the blade. The width of the horizontal slit must be considerably smaller than the diameter of the cord, so that the cord will not slip into horizontal slit. A vertical tab
215
and a horizontal tab
217
, generally at right angles to each other, form a gap
219
slightly smaller than the diameter of the cord.
FIG. 3
a,
FIG. 3
b,
and
FIG. 3
c
show steps in the operation of the backscrubber assembly. As shown in
FIG. 3
a,
the user attaches the removable washing element by pulling the cord through the V shaped cut into the vertical slit
14
. As shown in
FIG. 3
b,
the user then pulls the cord through the gap
219
between the vertical tab
215
and the horizontal tab
217
. The tabs kink the cord at a generally right angle to the direction of the cord through the slit. This kink keeps the cord from slipping as the backscrubber is used. As shown in
FIG. 3
c,
the user pulls the cord out of the vertical slit to remove the removable washing element
11
.
Details of the vertical slit
14
are shown in FIG.
4
.
FIG. 4
shows a cut away view of the bowl and the blade
29
looking down along the
4
—
4
plane of
FIG. 2
a.
As noted above in the discussion about
FIG. 1
, the width of the vertical slit
141
is slightly smaller than the diameter of the cord. A lip
143
extends along the side of the vertical slit opposing the blade. This lip increases the hold on the cord when the cord is in place. The lip forms a first pressure point. The edge of the blade forms a second pressure point. The first pressure point and the second pressure point are directed towards each other so that when the cord is in the slit, the first and second pressure points squeeze the cord between them, thus securing the cord by friction. Note that the lip and the blade are off-set. This off-set bends the cord rather than pinches the cord. This secures the cord without unduly fraying the cord.
The above-described arrangements are only illustrative of the application of the principles of the present invention. Numerous modifications and alternative arrangements may be devised by those skilled in the art without departing from the spirit and scope of the present invention. The appended claims are intended to cover such modifications and arrangements.
