Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a rubbish disposal device particularly
adapted for campers, trailers, motor homes or the like.
2. Description of Prior Art
For campers, trailers and the like, there has been no satisfactory
way of disposing of rubbish. The interiors of campers and trailers
necessarily provide very limited space. There is virtually no
location for placing a wastebasket or container without its
continually being in the way of the occupants. Any such waste
container must be rather small to fit within the confined space of
the interior, which means that it fills rapidly and necessitates
numerous trips to the rubbish disposal area. Alternatively, the
interior of the camper or trailer becomes littered with trash.
SUMMARY OF THE INVENTION
The present invention provides a practical and convenient means for
disposing of rubbish, particularly suitable for a unit, such as a
camper or a trailer, where space is at a premium. The invention
enables a removable rubbish container of substantial size to be
suspended along the exterior of the unit, rather than taking up
valuable space on the inside. The rubbish disposal device includes
a tubular chute of rectangular configuration extending through an
opening in one wall of the camper, trailer or other unit. This
tubular chute normally is closed by a spring-loaded door which can
be pressed to swing outwardly to uncover the opening through the
chute. A catch carried by the door maintains it in a closed
position when the unit is in motion, assuring that it is sealed and
preventing rattles.
The rubbish container may be an ordinary plastic wastebasket of the
type having a flat rear wall and preferably provided with an upper
lid so that the interior normally is closed. The flat wall of the
plastic rubbish container is provided with an opening dimensioned
to receive the outwardly protruding portion of the tubular rubbish
chute. The upper edge of the opening, which is reinforced with a
metal strip, rests upon the flat upper surface of the chute, which
suspends the rubbish container on the outside of the camper or
trailer. An upstanding flange on the upper surface of the rubbish
chute, spaced outwardly from the wall through which the chute
extends, retains the rubbish container so that it will not become
dislodged from the exterior portion of the rubbish chute.
The device is used by pressing open the pivotal spring-loaded door
to allow the rubbish to drop through the wall and into the rubbish
container on the outside. This means that the rubbish is quickly
and easily removable from the living quarters and, once discarded,
is completely sealed with respect to the interior of the unit. By
using a sizable plastic rubbish container, a large quantity of
refuse may be accommodated, minimizing the trips to the rubbish
disposal area to empty the container. The container is installed
easily by fitting it over the projecting portion of the rubbish
chute and positioning the upper edge of the opening through the
rubbish container between the flange on the chute and the outside
wall of the trailer or camper. Removal of the unit is equally
simple by lifting the upper edge of the rubbish container over the
flange, permitting the container to be separated from the rubbish
chute.
When the unit is in motion, the rubbish container is removed from
the outside and stored inside, ready to be reinstalled on the
projecting portion of the chute when a campground or other parking
place is reached. Over and above all these advantages, the rubbish
disposal unit of this invention is of low-cost construction and
readily installed in existing campers, trailers, motor homes and
the like.
BRIEF DESCRIPTION OF THE DRAWING

of this invention;
FIG. 2 is a rear elevational view of the rubbish container; and
FIG. 3 is an enlarged longitudinal sectional view of the rubbish
disposal unit attached to a wall.
DESCRIPTION OF THE PREFERRED EMBODIMENT:
The rubbish disposal unit 10 of this invention includes a short
tubular member 11 of rectangular cross section, which fits within
an opening 12 formed in a wall 13 of a camper or trailer. The inner
end 14 of the tubular member 11 is substantially flush with the
inner surface 15 of the wall 13. The outer end 16 of the tubular
member 11 projects beyond the outer surface 17 of the wall 13 and
may be scarfed as illustrated, tapering in length from top to
bottom. A peripheral flange 18 extends around the tubular section
11 and fits against the outer surface 17 of the wall 13 adjacent
the opening 12. Also, there is a frame 19 on the inner wall surface
14 extending around the entrance to the tubular member 11. The unit
11 is suitably held in place, such as by fasteners 21 that extend
through the wall 13 as well as through the flange 18 and the frame
19.
At the entrance to the tubular member 11 is a pivotal door 22,
mounted on a hinge 23 that extends horizontally at the upper edge
of the opening 12. This permits the door 22 to be rotated inwardly,
as indicated in phantom lines in FIG. 3. The door 22 preferably is
spring-loaded so that it will return to the closed position where
its lower edge is adjacent the inner surface of the bottom portion
of the peripheral frame 19. Also included on the door 22 at its
lower edge is a catch 24. This serves as a detent to mechanically
hold the door closed, preventing its rattling during movement of
the camper or trailer.
Rubbish is disposed of by pressing the door 22 outwardly, allowing
the refuse to be discarded through the member 11, which acts as a
chute. The rubbish is received within a container 26 which is an
adaptation of a conventional plastic wastebasket. The unit 26 has a
flat backside 27 that will fit adjacent the outer surface 17 of the
wall 13. It is desirable also that it have a pivotal lid 28 so that
the interior is normally closed to help retain the material within
it during its use. A rectangular opening 29 is formed in the wall
27 of the container 26, this opening being slightly larger than the
outside dimension of the tubular member 11. A U-shaped metal
reinforcement 30 is placed around the upper edge 31 of the opening
29 in the wall 27 of the container 26.
When the rubbish disposal unit is in its assembled position for
use, the container 26 is suspended from the tubular member 11. This
is very easily accomplished by fitting the container 26 over the
tubular member 11 at the opening 29 so that the U-shaped
reinforcement 30 of the container rests upon the flat upper surface
32 of the member 11. The reinforcement 30 is positioned behind an
upstanding flange 33 that extends across the upper surface 32 of
the tubular member 11. The flange 33 is spaced outwardly from and
parallel to the flange 18 that engages the outer surface 17 of the
wall 13. The upstanding flange 33 acts as an abutment that holds
the container 26 on the tubular member 11 so that it will not slide
off even if the unit is not parked on level ground so that the
upper surface 32 is not horizontal. This provides an effective
means for retaining the container 26, yet requiring no fasteners,
catches or other auxiliary devices.
With the container 26 suspended from the chute 11, the
reinforcement 30 prevents damage to the upper edge 31 of the
opening 29, adding to the strength of the container and increasing
its life. The scarfed outer edge 16 for the chute 11 helps direct
the refuse into the bottom of the container 26.
It is a simple matter to install the container 26 by lifting it
onto the tubular member, positioning the reinforcement 30 behind
the upstanding flange 33 and then allowing the lower portion of the
container to rotate inwardly toward the wall 13. Removal is an
equally simple operation by reversing this process.
In normal use, the container 26 is installed on the side of the
camper or trailer at the time it is parked, providing a convenient
means for disposing of rubbish directly to the outside, leaving the
interior of the camper or trailer free of a wastebasket or other
container for rubbish. The unit 26 may have a large capacity, so
that very few trips to the rubbish disposal area are required. At
the same time, the unit 26 is neat in appearance and does not
detract aesthetically from the camper or trailer. When the unit is
in motion, the container 26 is merely removed from the tubular
member 11 and stored inside. At that time, the slightly protruding
outer end 16 of the tubular member is unobtrusive, adding little or
no overall width to the camper or trailer. With the door 22 held
shut by the catch 24, the inside of the camper or trailer is
sealed, and there is no annoying rattling of the door.
An added advantage comes from utilizing a receptacle 26 with a lid
28 because it provides access to the interior of the receptacle
from the outside of the wall 13. Thus, the receptacle can be used
while cleaning the grounds outside the camper or trailer as well as
in disposing of rubbish from within. The receptacle 26 may be lined
with a paper bag so that washing is minimized, and may be used to
dispose of garbage as well as other rubbish.
The foregoing detailed description is to be clearly understood as
given by way of illustration and example only, the spirit and scope
of this invention being limited solely by the appended claims.
