SELF-CLEANABLE HAIR BRUSH
Abstract
A self-cleanable hair brush comprising a main body portion
having a handle at one end, a back normally disposed in contact
with one side of said main body portion, tufts of bristles secured
to said back and extending through openings in said body portion, a
plurality of pins rigidly secured to said body portion and normally
extending through apertures provided in said back, and a U-shaped
clip member pivotally secured to each pair of pins, said clip
members in normal operative position of the brush being secured to
the upper side of said brush, and said clip members being pivotable
to a position in which the legs of the U are in alignment with said
pins whereby said back and said body member may be moved away from
each other to a brush cleaning position in which the crossmembers
of the U-shaped clip members constitute abutments limiting movement
so that the back does not become disengaged from the tufts of
bristles.

Claims
I claim:
1. A self-cleanable hair brush comprising a main body portion
having a handle at one end thereof, a back having bristles attached
thereto, said bristles extending through holes provided in said
body part, a plurality of pins rigidly secured to said body portion
and extending from the surface of said body portion perpendicular
thereto, said back having holes extending therethrough slightly
larger than the outer diameter of said pins to enable said pins to
extend through said holes in the operative position of the brush,
said back being movable to and away from said body portion,
abutment means comprising at least one U-shaped member pivotally
secured to a pair of said pins to limit the extent of movement of
said back relative to said body member, said U-shaped member in the
operative position of the brush being pivoted to a position against
the surface of said back, and locking means to lock said U-shaped
member against said back.
2. A self-cleanable hair brush according to claim 1, wherein there
are four of said pins disposed in two pairs and one of said
U-shaped members pivotally connected to each pair of pins, said
abutment means comprising a cross member of each of said U-shaped
members, and said locking means comprising locking pins rigidly
connected to said cross members and in the operative position
thereof being locked in recesses provided in the surface of said
back.
Description
The present invention relates to an easily cleanable hair brush
which incorporates means for cleaning the hair brush when it
becomes clogged or matted with hairs and other debris.
It is a principal object of the present invention to provide an
improved hair brush which incorporates means whereby hair, dandruff
etc., which collects on the bristle tufts can be quickly and easily
moved in essentially one manipulative operation.
Another object of the present invention is to provide a
self-cleanable hair brush having an improved structure for both
normally locking the relatively movable parts together in the
normal operative position of the hair brush and also serving as
means for limiting the relative movement between said parts to
prevent the cleaning member from being moved beyond the ends of the
tufts whereby the tufts would become disengaged therefrom.
A presently preferred embodiment of the present invention comprises
a main body portion having a curved handle at one end, a back with
bristles embedded therein, holes in the body portion through which
the bristles project, upstanding pins rigidly secured to the body
portion, holes in the back through which the pins extend during
normal use of the brush, said back being movable to and away from
said body portion, abutment means comprising at least one U-shaped
member pivotally secured to a pair of said pins to limit the extent
of movement of said back relative to said body member, said
U-shaped member in the operative position of the brush being
pivoted to a position against the surface of said back, and locking
means to lock said U-shaped member against said back.
The above and other objects, features and advantages of this
invention will become more apparent from the following description
of a presently preferred embodiment of the invention, taken in
conjunction with the accompanying drawing wherein:
FIG. 1 is an elevational view of a preferred embodiment of a hair
brush of the invention shown in its normal operating position with
the bristles extending upwardly.
FIG. 2 is a bottom view of the embodiment shown in FIG. 1.
FIG. 3 is an elevational view partly in section showing the hair
brush of FIG. 1 in the cleaning position, with the hair brush
rotated 180.degree. from the FIG. 1 position so that the bristles
extend downwardly.
FIG. 4 is an end view of the hair brush in the cleaning position as
shown in FIG. 3.
Referring now to the drawing, and more particularly to FIG. 1, the
hair brush of the invention comprises a main body portion 10 having
a plurality of holes 12 through which tufts of bristles 14 extend.
A curved handle 16 constitutes an integral extension of the body
portion 10.
Tufts of bristles 14 are secured in holes in a back 18. As seen in
FIG. 1, the back 18 is normally disposed against the adjacent side
of the body portion 10 when the brush members are in their normal
operating position.
Two pairs of pins 20 are rigidly fastened to body portion 10 and
project therefrom perpendicular to the surface of body portion 10.
It will be noted that the brush increases in width from the handle
side to the left hand side of the brush as seen in FIG. 2. The
left-hand pair of pins 20 are spaced a greater distance from each
other than the right-hand pair of pins 20 in the presently
preferred embodiment.
The back 18 has four holes 22 aligned with the pins 20 and slightly
larger than the outside diameter of pins 20 so that when the back
18 abuts against body member 10 in the operative position of the
brush, pins 20 extend through the holes 22. Smaller and larger
U-shaped clip members 24 and 26 are pivotally connected to the
right-hand and left-hand pair of pins 20, respectively, by pivot
pins 28.
As clearly illustrated in FIGS. 1 and 2, the U-shaped members 24
and 26 in the operating position of the brush are pivoted
downwardly and abut against the adjacent surface of the back 18. In
this position, locking element 30 comprising pins having enlarged
heads which are secured to the underside of the crossmembers of the
U-shaped members 24 and 26 are received in resilient locking
engagement within complimentary shaped recesses 32 in the surface
of back 18. When the locking elements 30 are in this position, back
18 is maintained in contact against the adjacent surface of body
portion 10 without any movement or play between the elements.
Whenever it is desired to clean the brush, the U-shaped members 24
and 26 are pulled away from the back 18 to remove locking elements
30 from their recesses 32. The U-shaped members 24 and 26 may then
pivot around pins 28 to positions in which the legs 34 of the
U-shaped members are substantially aligned with pins 20. At this
time, back 18 may be moved relative to body member 10 with the legs
34 entering into the holes 22 in the back 18 as best seen in FIG.
3. The relative movement between body portion 10 and back 18
continues until back 18 abuts against the crossmembers of the
U-shaped members 24 and 26 which constitute abutment members which
prevent the relative movement from causing the bristles 14 from
being entirely withdrawn through the holes 12 in body portion 10.
Preferably, the extent of the relative movement is such that the
free ends of bristles 14 are just drawn to or slightly into the
holes 12 in body portion 10. It will of course be appreciated that
this is achieved by suitably coordinating the length of pins 20 and
the legs 34 of the U-shaped members with the length of the
bristles. In this fashion, hair and other debris which is
accumulated on and between the bristles 14 is moved along the
bristles to their free edges by the relative movement between back
18 and the body portion 10, and either falls off the brush or
accumulates on the upper surface of body portion 10 from which it
is readily discarded. With the brush in the position illustrated in
FIG. 3, the brush may now be wiped clean with tissue or with
running water etc., if necessary. Body portion 10 is made
sufficiently thick so that there is sufficient leeway to insure
that the bristles 14 do not pass completely through the holes
12.
While a preferred embodiment of the invention has been shown and
described in detail, it will be appreciated that various changes
and modifications may readily suggest themselves to those of
ordinary skill in the art upon being apprised of the present
invention without departing from the scope and spirit of the
present invention.
