Claims
I claim:
1. A pet brush comprising an elongated, substantially flat base
member having a suction chamber therein and a central opening in
one side thereof communicating with said chamber, bristles on said
one side of said base member disposed around the marginal portion
thereof and about said opening, said base member and bristles being
integrally molded in one piece of flexible material and including
an integral tubular suction connection on one end of said base
member communicating with said chamber, and a mitt affixed to the
opposite side of said base member, said suction connection
extending from said base member in generally parallel relation with
the wrist portion of said mitt, said base member being capable of
being curved by an operator's hand in said mitt to correspond to
the surface of an animal being brushed.
2. A pet brush as defined in claim 1, said base member having a
sidewall and an inturned flange on said sidewall spaced from the
mitt side of the base member, said mitt side of said base member,
sidewall and flange forming said suction chamber, said flange
defining the margin of said opening, and said bristles projecting
from said flange.
Description
BACKGROUND OF THE INVENTION
This invention relates to a brush equipped with suction means for
removing loose hair, for use by veterinarians and owners of
animals.
In grooming an animal, the disposal of loose hair creates a
problem. There is a need for a device to remove and dispose of
loose hair so that it will not fall on the floor and so that it
will not pack between the bristles of the brush.
Objects of the invention are to provide an improved pet brush, to
provide a brush with suction means and to provide a flexible brush
of the type described equipped with a mitt to receive the hand of
the operator.
SUMMARY OF THE INVENTION
Two embodiments are disclosed. In the first embodiment a rigid base
member has rows of flexible plastic bristles disposed around its
periphery. A central cavity communicates with a suction connection
for attachment to a vacuum cleaner hose for removing any loose hair
or other material that may be dislodged by the bristles. The
airflow through the brush tends to keep it clean and prevents hair
from falling on the floor.
The second embodiment has a flexible base connected with a mitt to
receive the hand of the operator. Thus, the operator may curve the
brush around the back, neck and legs of the animal for more
effective brushing.
The invention will be better understood and additional objects and
advantages will become apparent from the following detailed
description of the preferred embodiments illustrated on the
accompanying drawing. Various changes may be made in the details of
construction and arrangement of parts and certain features may be
used without others. All such modifications within the scope of the
appended claims are included in the invention.
BRIEF DESCRIPTION OF THE DRAWING
FIG. 1 is a perspective view of a first embodiment of pet brush
embodying the principles of the invention;
FIG. 2 is a side elevation view;
FIG. 3 is a top plan view;
FIG. 4 is a bottom plan view;
FIG. 5 is a perspective view showing a modification; and
FIG. 6 is a sectional view on the line 6-6 in FIG. 5.
DESCRIPTION OF THE PREFERRED EMBODIMENTS
In FIGS. 1 to 4, a flat and substantially rigid base member 10 has
rows of bristles 11 around its periphery. The bristles preferably
vary in length from the front to the back end of the base member as
shown in FIG. 2. This allows the operator to apply pressure
primarily against the short bristles in brushing short hair and to
apply pressure primarily against the long bristles in brushing long
hair. Thus, a single brush is adapted for brushing both short hair
and long hair. A preferred bristle pattern is illustrated in FIG. 4
but this pattern may be varied without departing from the spirit of
the invention.
Base member 10 has a central opening 12 communicating with a cavity
or chamber 13 in a housing part 14. The lower edges of housing part
14 are integrally united with the top of base member 10 about the
opening 12. The top of housing 14 is preferably provided with an
air hole 15 which communicates with chamber 13. Housing 14 has an
inclined rearwardly extending cylindrical part 16 which terminates
in a tapered tubular adapter 17 for connection with the suction
hose of a vacuum cleaner. The taper allows hoses of different size
to be fitted snugly onto the adapter in order to establish suction
in chamber 13.
Housing part 14 and adapter portion 17 provide a convenient handle
to be grasped by the operator. In brushing an animal, the hole 15
may be completely closed by the forefinger to establish maximum
suction in chamber 13. When less suction is desired, the hole 15
may be partially or completely uncovered to admit air to chamber
13.
Preferably, the body 10, bristles 11, housing 14 and adapter 17 are
all integrally molded in one piece from a suitable plastic, such as
polyethylene.
FIGS. 5 and 6 show a modification having a mitt 20 to receive the
hand of the operator. The palm side of mitt 20 is fixedly secured
to a flexible base member 21 having rows of bristles 22 which are
preferably of uniform length. The bristle pattern is preferably the
same as in FIG. 4 and, in bottom plan view, the base member 21 is
also substantially as shown in FIG. 4 having a central opening 23
corresponding to the opening 12 and a suction chamber 24
corresponding to suction chamber 13.
The rear end of the base member 21 terminates in a tapered tubular
adapter 17 for transmitting suction from a vacuum cleaner suction
hose 25 to the chamber 24. Wrist portion 26 of the mitt preferably
extends adjacent and generally parallel with the adapter 17 so that
hose 25 will readily follow the movements of the operator's
arm.
Base member 21, bristles 22 and adapter 17 are preferably
integrally molded in one piece from a suitable plastic, such as
polyethylene. The composition of the plastic and the thickness of
the wall sections are controlled to produce a desired degree of
flexibility for curving the base member by the operator's hand in
the mitt, as shown. Thus, the curvature may be varied to correspond
to the surface of the animal being brushed, such as its back, legs,
neck, etc. An air hole 15 is not necessary in the embodiment in
FIGS. 5 and 6 as the suction may be reduced at will by either
increasing or decreasing the curvature of base member 21 to admit
excess air through opening 23. Any hair that may accumulate in the
bristles is readily disposed of by dislodging it into the airstream
entering opening 23.
