BAMMUND OF THE INY-ENTION

Field of the invention :

The invention relates generally to household accessories but more particularly
to a
lifter for pet food or water bowls.

Background of the invention :

For practical as well as health reasons, devices aimed at raising and lowering
the
food or water bowls of pets have been developed. Indeed, some pet owners have
various conditions that do not allow them to bend easily so any device aimed
at
avoiding that is welcome.

There are of course several inventions aimed at performing that specific
function but
there is always a need for a simple and practical way of achieving that.

$4MMARY OF THEINI/ENTIO~V

The invention consists in a channel through which slides a riser lifting a
hook onto
which is hooked either a platform or a bowl or any such container_ A handle
allows the

user to raise the hook to any desired height at which point it is
automatically locked to
that given height_ By actuating a lever, the hook can be lowered.

There has thus been outfined, rather broadly, the more important features of
the
invention in order that the detailed description thereof that follows may be
better
understood, and in order that the present contribution to the art may be
better
appreciated, There are additional features of the invention that will be
described
hereinafter and which will form the subject matter of the claims appended
hereto.
In this respect, before explaining at least one embodiment of the invention in
detail, it
is to be understood that the invention is not limited in its application to
the details of
construction and to the arrangements of the components set forth in the
following
desciiption or illustrated in the drawings. The invention is capable of other
embodiments and of being practiced and catried out in varPous ways. Also, it
is to be
understood that the phraseology and terminology employed herein are for the
purpose of description and should not be regarded as Iimiting.
As such, those skilled in the art will appreciate that the conception, upon
which thls
disclosure Is based, may readily be utilized as a basis for the designing of
other
structures, methods and systems for carrying out the several purposes of the
present
invention. It is important, therefore, that the claims be regarded as
including such
equivalent oonstructions insofar as they do not depart from the present
invention.

These together with other objects of the invention, along with the various
features of
novelty which characterize the invention. are pointed out with particularity
in the
daims annexed to and forming a part of this disclosure. For a better
understanding of
the invention, its operating advantages and the specfic objects attained by
its uses,
reference should be had to the accompanying drawings and descriptive matter in
which there is iiiustrated preferred embodiments of the invention.

DETrA1LED DESCRIPTIQN OF THE PREFERRED iEKBODIMENT

A food lifter (10) has a channel frame (12) having a main channel (13)
configured and
sized for receiving a riser (14) slindingly engaging the main channel (13).
The riser
(14) has a hook (16) at its lower end extending therefronrr and used for
hooking a bowl
assembly (17) or a shelf or platPorrn (40) as per FIG. 7 for supporting a
generic bowl
(not shown) or any other suitable objeck_ The nser (14) has a handle (18)
along most
of the iength of the riser (14) with several points of attachment (21) to the
riser (14)

which allows the user to raise or lower the riser (14) from a wide range of
location so
that no matter the position of the handle (18) or the height of the user, the
handle (18)
is aNvays within reach. According to the height or preference of the user,
once the
bowl assembly (17) has reached a certain height, a ratchet means (15) situated
atop
the channel frame (12) actuated by a lever (19) stops the riser (14) from
moving
downward by using a set of teeth (20) positioned along the length of the riser
(14) on
the side opposite that of the handle (18) with all teeth (20) extending from
the riser
(14). The teeth (20) interaet with a pawl (22) and its biasing means (24) so
that the
pawl (22) is always biased against the teeth (20) exoept when the user pulls
on it with
the lever (19) such as when lowering of the riser (14). Once the platform (16)
is raised
and set at a preferred height, the user can interact with it. The teeth (20)
and pawl
representing the main component of the ratchet means (15), one understands
what
orientation the teeth (20) should have if an upward pull allows for free
sliding of the
riser (14) within the channel frame (12) while a pull on the pawl (22) is
required for
lowering the riser (14). The channel frame (12) has a pair of side channeis
(52)
running parallel to the main channel (13) and into which slide guides (50)
found on the
bowl assembly (17) or the platform (40)_

The bowl assembly (17) is a custom made twin bowl unit having an opening (30)
through which engages the hook (16) which will raise the bowi assembly (17) as
the
riser (14) is risen. The configuration of the bowl assembly (17) can of course
differ
from that illustrated but a twin bowl is preferred as it can hold water In one
bowl and
food in the other. As discussed earlier, a platform (40) can repiace the bowl
assembly (17) as long as it has an opening (30) that fits the hook (16). To
allow some


CA 02510222 2006-06-06

room for the ratchet means (15) as well as alearing baseboards (not shown)
spacer
blocks (34) set a distance between a surface (36) such as a wall and the
channel
frame (12).

As to a further discussion of the manner of usage and operation of the present
invention, the same should be apparent from the above description.
Accordingly, no
further discussion reiating to the manner of usage and operation will be
provided.
With respect to the above desaription then, it is to be realized that the
optimum
dimensional relationships for the parts of the inventiQn, to indude variations
in size,
materials, shape, form, func#ion and manner of operation, assembly and use,
are
deemed readily apparent and obvious to one skilled in the art, and all
equivalent
relationships to those illustrated in the drawings and descrbed in the
specification are
intended to be encompassed by the present invention.

Therefore, the foregoing is considered as illustrativa only of the principles
of the
invention, Further, since numerous modifications and changes wili readily
occur to
those skilled in the art, it is not desired to limit the invention to the
exact r.nnstn,ntir,n
and operation shown and described, and accordingly, all suitable modifications
and
equivalents may be resorted to, failing within the mope of the invention_
