Description
My invention relates to shower equipment as a part of camping
apparatus and more particularly to an improved recirculating
portable shower for campers, trailers or automobiles and
particularly adapted for use in sites where running water is not
available.
Portable and collapsible shower equipment are known and in use.
Such apparatus is particularly adapted for use in areas or in camp
sites where bathing facilities are not readily available. They have
previously been built into campers or trailers and as such have
been collapsible. However, all prior designs have required a
pressurized water source and additional equipment for heating or
tempering water. Further, where they have been applied to campers,
they required complex built-in structures not readily available for
modification of existing equipment. Separate collapsible and
portable units have been complex in structure and required
additional equipment making such structures not readily storable or
portable.
My improved portable and collapsible shower apparatus provides a
structure which is truly portable and compact and readily available
for usage in areas where running water or pressurized water sources
are not available and which may be readily built-in or attached to
existing camping equipment with a minimum amount of
modification.
My improved portable and collapsible shower in its portable or
carrying form includes a boxlike base structure defining a
reservoir for water in which is positioned a submersible pump
operated by an electric motor and adapted to be energized from a
battery source of a vehicle through an electric cable fitting into
a cigarette lighter attachment or directly attaching to the battery
cables. The boxlike structure houses a tubular frame which attaches
thereto to form an enclosure upon which a curtain is mounted. The
pump is connected to a flexible hose with a shower head thereon
which is adapted to be connected to the upper part of the frame for
a conventional shower attachment. The reservoir includes a step
portion upon which a person would stand. Tempered water is placed
in the reservoir prior to usage and the pump moves the water
therefrom through the shower head with the water being returned to
the reservoir. Energization of the pump is effected through
connection of the same to the battery source, as indicated above.
This same principle or apparatus may be readily installed in an
existing camper by positioning the same in a table location wherein
the base structure forms a floor section and support for the table.
The table is readily removable and the seating arrangement defines
the enclosure opening with the enclosure mounting being as in the
portable structure or suspended from the roof of a camper with the
same submersible pump moving water from the reservoir through the
shower head and returning the same to the reservoir. The principle
of operation of this shower unit is similar to a tub in that the
same water is utilized rather than discharged water as it is used.
This enables the user to merely fill the reservoir with water of a
desired temperature for showering.
Therefore it is the principle object of this invention to provide
an improved portable and collapsible shower for camping.
Another object of this invention is to provide a portable showering
apparatus particularly applicable at sites where pressurized water
sources are not available.
Another object of this invention is to provide a collapsible shower
apparatus requiring a limited amount of storage space and which is
readily erected for usage.
A further object of this invention is to provide a portable
showering apparatus of this type which is energized from a battery
source.
A still further object of this invention is to provide a portable
and collapsible shower apparatus which may be readily installed in
existing camping equipment or campers.
A further object of this invention is to provide a portable
showering apparatus requiring a low voltage power supply to present
no danger of electrical shock to the user.
These and other objects of this invention will become apparent from
a reading of the attached description together with the drawings
wherein:
FIG. 1 is a perspective view of my improved portable and
collapsible shower apparatus in an erected position,
FIG. 2 is a perspective view of the showering apparatus of FIG. 1
in a collapsed and stored position,
FIG. 3 is a perspective view of a portion of a camper showing the
improved portable showering apparatus in a stored condition,
and
FIG. 4 is a perspective view similar to FIG. 3 showing the
showering apparatus in an erected position.
My improved portable and collapsible shower for camping is shown in
FIGS. 1 and 2 as a collapsible and portable unit. It includes a
base structure, indicated generally at 10, which as will be seen in
FIG. 2 forms the carrying case for the shower in the collapsed
position. The base structure includes a bottom wall 12, side walls
11, end walls 15, and a foldable top wall 16 with flap portions 17
hinged thereto. In the open position the base structure forms a
watertight structure which is the reservoir for the shower into
which water is positioned, as will be hereinafter noted. Attached
to the sidewalls or base walls is a raised step portion 20 upon
which the person using the shower will stand to be raised above the
normal depth of water in the reservoir. This structure is
preferably made of wood although other materials may be utilized
therein. Positioned in the reservoir is a submersible pump 30
having an inlet 32 and an outlet 34, the pump being powered by an
electric motor of the low-voltage type (not shown) which has
connected thereto electric lead lines 35 having suitable length and
with a bayonet type connector 36 at the extremity of the same
adapted to fit into a cigarette lighter receptacle of a standard
automobile. As an alternative, a pair of clips (not shown) may be
utilized at this extremity to connect the motor or lead lines
directly to the battery of an automobile. The electric motor is of
the low-voltage type for operating from the standard car voltage or
battery voltage. The motor will run when the clips are connected to
the battery source and remain running until the lead lines are
removed therefrom. Outlet 34 of the pump which is positioned within
the base structure and attached to a sidewall or bottom wall
thereof, is connected to a rubber hose 40 with a sufficient length
to reach the top of a shower enclosure, indicated generally at 50,
to be hereinafter identified. At this extremity of the hose, a
shower head 52 is connected, the shower head having a curved neck
and a discharge opening 53 therein with a suitable hook 54 to
attach the same to the enclosure. The enclosure or curtain support
50 is formed of a plurality of tubular members 55 which fit
telescopically into one another and mount on the end walls of the
base structure through suitable brackets 60. The upper portion of
the enclosure is formed by a generally rectangular frame structure
65 having suitable cross braces 66 therein and downwardly extending
tubular members 67 which fit onto the upper tubular members 55 of
the enclosure. The width and length dimensions of this rectangular
frame are less than the interior dimensions of the rectangular base
structure such that the same may be positioned therein in the
collapsed position of the shower. Similarly the length of the
tubular members 55 are such as to fit within the enclosed case in
the dismantled position of the shower. The brackets and lower
tubular members of the enclosure are slightly inclined so that when
the tubular members are erected or connected, they will fit into
the depending tubular portions 67 of the head frame to rigidly
mount the same. Positioned on the head frame are a plurality of
rings 80 having suitable snaps thereon which fit through eyelet
holes 82 in the shower curtain 84 for the purpose of mounting the
same on the head frame.
The portable shower is readily erected at a camp site or place of
usage by merely opening the top flap 16 of the base structure 10
and extending the flap portions 17 so that they ride on the side
and end walls 11 and 15 of the base structure. The tubular sections
55 are removed and installed placing the same through the
supporting brackets on the end walls of the base structure with the
head frame being mounted at the top of the same. Thereafter the
curtain is attached by positioning the rings 80 through the eyelets
82 in the curtain 84 suspending the same and attaching the shower
head 53 to the head frame by means of the ring 54. The rubber hose
will normally be connected to the shower head and motor and will
fold in the collapsed position such that it merely may be stretched
and suspended from the head frame for installation. Thereafter and
for usage, water which has previously been heated is poured into
the reservoir and the electric lead lines 35 are connected to the
battery source either through the plug 36 in the cigarette lighter
of a vehicle or directly to the battery, if battery clips are
positioned on the extremities of the lead lines. Water will be
pumped from the reservoir through the rubber hose or flexible
conduit to the shower head wherein it will be sprayed down the
enclosure and returned to the reservoir. The water, similar to bath
water, will be recirculated to enable a person to shower at a
location where running water is not available. The entire structure
may be readily collapsed and stored by reversing the procedure and
the complete portable shower is housed in a case defined by the
base structure with a suitable carrying handle 90 for positioning
the same. Thus it may be readily stored and handled for
camping.
An alternate embodiment of the structure is shown in FIGS. 3 and 4
applying the same structure to the interior of a camper. Although
the camper frame is not shown, the seating structure 100 is
indicated as a dinette section of a conventional camper having a
table 102 supported therein. The problem of applying a shower to a
nonmodern trailer or camper is finding the physical space to erect
the same. The improved collapsible and portable shower may be
readily applied to the seating or dinette area of such campers
which normally have a 2 by 3 foot opening around the seats to
position the table 102 therein. These are the approximate
dimensions of the base structure or case 10 shown in FIGS. 1 and 2
and the same may be readily inserted by removal of the table and
providing a mounting for the same on the lid structure 16 or top
wall of the base structure which mounting would provide for readily
removing the table base therefrom. Thus the base structure 10
applied to the existing trailer in the dinette area would merely
raise the table and floor structure within the seating area by the
height of the case. This structure would be erected for usage in
the same manner where tubular portions are used. In the embodiment
shown in FIG. 4, the poles are omitted since the ceiling of the
camper or trailer may provide hooks 105 to suspend the head frame
65 of the enclosure eliminating the need for the tubular portions
to mount the same directly to the base. Thus in FIG. 4, the head
frame 65 with the rings 80 thereon mounts the curtain 84 directly
to the ceiling and the submersible pump 30 in the reservoir portion
of the base structure will have attached thereto the flexible hose
40 leading to the shower head 53 which would be suspended from the
frame by means of the hook 54. The structure would be used in the
same manner by heating or tempering water and pouring the same into
the reservoir. The motor would be connected to a power source such
as the battery and through the leads 35 which we could connect to
existing battery wiring in the trailer or to the vehicle associated
therewith. The collapsible and portable shower functions in the
same manner in that it pumps water from the reservoir through the
shower head with the water being returned to the reservoir to be
recirculated for showering purposes. The head frame 65 and curtain
together with the shower head 53 and hose 40 all collapse and store
the same within the base structure 10 when not in usage. Water may
be removed from the reservoir when the shower is not in use by
continuing pumping operation and directing the shower head to some
point remote from the trailer.
In my improved portable and collapsible shower, I have provided a
structure which forms a reservoir into which tempered water may be
placed and pumped to a shower head. This water will be recirculated
and the base structure provides means for mounting an enclosure for
privacy of the user. The entire structure is readily erected and
dismantled as well as being stored within the base structure in the
closed position. In the case of the camper, removal of the table
support and table may be readily facilitated through the mounting
of the same thereon which would be detachable.
In considering this invention it should be remembered that the
present disclosure is illustrative only and the scope of the
invention should be determined by the appended claims.
