Water filter description
BACKGROUND OF THE INVENTION
The invention relates to water filters and more specifically to
portable water filters for removing dirt, grit, unpleasant tastes
and odor from water for use with recreation vehicles.
Presently available portable water filters, such as, described
in U.S. No. Pat. No. 1335282 are large and incompatable for use
with recreation vehicles which have limited storage space.
The water filter taught by U.S. Pat. No. 3585130 while operable
does not provide ease of filter element replacement, compactness
and requires a pressure valve to limit the water pressure to the
container to some value less than normally provided by commercial
water systems.
Neither of the present art filter apparatus provide for a convenient
portable water filter for recreation vehicles and the like.
SUMMARY OF THE INVENTION
In accordance with the invention claimed is a convenient portable
water filter and carrying case combination that can be conveniently
stored as loose equipment when not in use and quickly installed
exterior of the vehicle when its use is required.
It is therefore, one object of this invention to provide a means
of filtering potable water from any pressurized water source.
Another object of this invention is to provide a portable water
filter of a size small enough to be conveniently stored in a small
area of a recreation vehicle when not in use and easily and quickly
made operative when required.
Another object is to provide a portable water filter that can be
concealed and protected by its carrying case when not in use.
Still another object is to provide a carrying case that not only
provides storage for the filter canister but also provides storage
for filter attachment accessories.
Further objects and advantages of the invention will become apparent
as the following description proceeds and the features of novelty
which characterize this invention will be pointed out with particularity
in the claims annexed to and forming part of this application.
BRIEF DESCRIPTION OF THE DRAWINGS
The present invention may be more readily described by reference
to the accompanying drawings in which:
FIG. 1 is a perspective view of the portable water filter of the
invention including its hook-up accessories;
FIG. 2 is a cutaway end view of the FIG. 1 showing with the lid/mounting
board installed on the container as a lid;
FIG. 3 is a showing of lid/mounting board with a filter and valve
attached;
FIG. 4 is a side view of the FIG. 3 showing.
DESCRIPTION OF THE PREFERRED EMBODIMENTS
Like reference numerals used throughout the description denote
the identical element or part.
Referring now more particularly to the drawings, FIG. 1 shows a
perspective view of the portable filter unit ready for operation.
The canister 10 containing a filter element of activated charcoal
or the like is shown supported by the lid/support member 12 held
in place by slots 14 shown on one end of base/container 16 in FIGS.
1 and 2. The slots 14 may be cut or formed (not shown) into the
upright walls 18 or provided by a pair of cleats so positioned on
each inner opposed wall 18 of container 16 to form the slot. The
cleats are spaced apart a distance slightly greater than the width
of the lid/support 12 so that the lid/support easily slips within
the slots provided. The cleats may be secured to the walls 18 in
any suitable manner, not limited to nut and bolt combinations 22
as shown.
Two opposing walls 18 are shorter in height than the other walls
by an amount equal to the thickness of lid/support 12. This allows
the lid/support 12 to fit flush with the longer side walls as shown
in FIG. 2. This feature provides a smooth overall outer profile
of the portable filter for storing when not in use.
The container 16 and lid/support 12 may be constructed with such
dimensions that the lid/support 12 could fit flush with the upper
wall surfaces and still be able to slip into slots as hereinbefore
described.
The container base 24 is made and installed in a similar manner
as the lid/support member 12. The base 24 unlike lid/support member
12 is permanently attached to the four walls 18 in a conventional
manner, such as, but not limited to glue, screws, glue and screws,
and the like.
One outside wall surface 18 is provided with a fold up handle 26
suitably constructed to support the weight of the portable filter
and its accessories.
The container base, side walls and lid/support may be constructed
of any suitable material such as, metal, wood, fibre glass, resin
system or the like.
The canister and filter element may be of any commercially available
type for removing dirt and rust particles and removing unpleasant
tastes and odors from potable water. An example of a suitable canister
and filter element would be those made by Cuno, a division of AMF
or the canister and filter element described in U.S. Pat. No. 3780867
or the equivalent.
The canister 10 containing a filter element is attached to lid/support
12 by a pair of Wing ell fittings 28 positioned on each side of
the filter. These Wing ells 28 are attached to the lid/support in
a manner so that their respective input and output conduits 30
32 respectively, can be conveniently attached to and support the
canister. It should be noted that the position of the input and
output conduits are not limiting and may for some canisters be positioned
in the reverse that is shown for canister 10. The Wing ell fittings
each have a pair of apertures 34 for mounting the Wing ell to the
lid/support member. The Wing ell may be mounted, as shown in FIG.
2 by nut and bolt combinations 36 or any other suitable manner.
It should be obvious that the canister and conduits may be attached
to the lid/support by any conventional means.
The unattached outer ends of the input and output conduits are
provided with either a female or male hose coupling 38 40 respectfully.
In some uses, the input may have a female while the output has a
male or the reverse or both may have a male or female depending
on the water system input and output hook-up requirements. On a
conventional system, the input would have a female coupling and
the output a male coupling.
Referring now specifically to FIG. 2 when the canister is in its
inoperative or stored position, where the lid/support is installed
as a lid and held in place by easily removable screws 41 wingnuts
or the like there is provided a storage compartment 42 for storing
interconnecting hoses 44 and the like, as well as any other desired
accessories not shown.
Some uses for the portable filter require a valve means 46 shown
in FIGS. 3 and 4 for shutting off the outflow from the filter element
within the canister when no filtered water is required.
OPERATION OF THE PREFERRED EMBODIMENT
When the portable filter is not in use it is stored, as shown in
FIG. 2. When operation of the portable water filter is desired the
securing screws 41 are removed, the lid is raised and the accessories
are removed from the container, the lid is inserted within the slots
14 in its support position, and the screws 41 are replaced in the
container for storage.
It should be easily understood that the container 16 provides a
base for the support of the canister when the canister is in its
operative position as shown in FIG. 1.
The input hose is attached to a pressurized water supply to be
filtered, not shown, in a conventional manner. The output hose is
installed between the output of the canister and the water supply
input of a recreation vehicle 48 or the like. The water supply is
then turned on, flowing in the direction of arrow 50 and the supply
water will be filtered on demand as water is utilized by operation
of the recreation vehicle output water valve, not shown.
In the operation of the portable water filter, when its output
is not normally connected, the valve 46 is turned to its off position
and filtered water can be drawn on demand by operating the output
valve to its on position.
As can be readily understood, the canister or any of its conduit
means may be readily replaced or repaired by separating the lid/support
from the container so as to provide easy accessability to the components.
Many changes may be made in details of the instant invention, in
the method and materials of fabrication, in the configuration and
assemblage of the constituent elements, without departing from the
spirit and scope of the appended claims, which changes are intended
to be embraced therewithin. |
