Description
BACKGROUND OF THE INVENTION
The present invention refers to supports for containers,
receptacles and the like and more in particular to a collapsible
support for a refuse receptacle, such as for instance, a disposable
garbage bag.
Refuse receptacles commonly consist of solid containers made of
sheet metal or plastic and generally stored outside a building for
deposit of refuse therein. These containers, when emptied, become
dented and otherwise damaged to the point that their use is limited
to a short period of time. In addition, if these containers are not
protected against atmospheric surroundings, particularly in regard
to metal containers, they will rust and their usefulness will be
cut short, requiring more frequent replacement.
In order to eliminate or reduce the above disadvantages of
conventional refuse containers, the present invention contemplates
the provision of a collapsible support for disposable refuse
containers, such as plastic garbage or refuse bags.
The proposed receptacle support, according to the present
invention, comprises an open frame work composed of an upper frame
member and a lower frame member separated and connected together by
a pair of spacer bars adapted to retain the frame members in a
position to receive a receptacle, such as a bag, which upper edge
can be draped around the upper frame member to support the
receptacle within the frame work.
Selectively, a solid bottom can be provided for the lower frame
member and a solid cover for the removable attachment to the upper
frame member to protect the receptacle against atmospheric
surroundings. The solid bottom, if provided, can be equipped with
caster wheels so as to enable the receptacle support to be rolled
around a ground surface. Likewise, the cover, is provided, can be
hingely attached to the framework of the receptacle support to
permit easy opening and access to the receptacle retained by the
support.
The primary feature of the present invention resides in the
provision of a frame work for a receptacle support which is
constructed such as to be collapsible into a flat position when not
in use for storage or transport to another location.
Other features and advantages of the present invention will become
more readily apparent or be particularly pointed out by reference
to the following detailed description in connection with the
appended drawing.

FIG. 5 is an enlarged cross-section through the top section of the
receptacle support shown in FIG. 3; and
FIG. 6 is an enlarged detailed view of the construction and
arrangement of the frame work of the basic receptacle support
illustrated in FIG. 1.
DESCRIPTION OF THE PREFERRED EMBODIMENT
With reference now to FIGS. 1 and 6, the collapsible receptacle
support of the present invention is comprised of a frame work
generally indicated at 10 composed of a lower frame member 12 and
an identical upper frame member 14 spaced apart by a pair of spacer
bars or rods 16 and 18, respectively.
The spacer bars 16 and 18 when in a position as shown in FIG. 1,
retain the lower frame member 12 and upper frame member 14 in
parallel horizontal relationship relative to each other when the
lower frame member 12 is supported on a surface, to permit the
insertion and support of a receptacle, such as a disposable garbage
bag 20, indicated in dot-and-dash lines, which extends through the
upper frame member 14 downwardly towards the lower frame member 12
and which upper edge may be crimped over around the upper frame
member 14 for support of the receptacle within the frame work.
Both upper and lower frame members 12 and 14 are preferrably of
ring like structure fabricated from a length of steel or plastic
rod and welded together to form a ring. The spacer bar 16 is
preferrably fabricated from the same rod like material as the frame
members 12 and 14 and is provided at both its ends with eyes 15 and
17 respectively which slidingly engage the frame members 12 and 14
for circumferential movement of the spacer bar 16 around the frame
members 12 and 14 and for pivotal movement of the frame members 12
and 14 relative to the spacer bar 16.
The opposite spacer bar 18 is of substantially identical structure,
comprising eyes 19 and 21 at the ends thereof which pivotally
engage the frame members 12 and 14. The spacer bar 18, however, is
restrained against circumferential movement around the frame
members 12 and 14 by means of braces 22 and 24, respectively,
welded or otherwise secured to the frame members 12 and 14 to clamp
the eyes of the spacer bar 18 in between them.
Thus, the spacer bar 18 is prevented against circumferential
movement along the frame members 12 and 14 but does not prevent
pivotal movement of the frame members 12 and 14 relative
thereto.
With particular reference to FIG. 6, in order to collapse the
receptacle support 10 into a flat inoperative position, the movable
spacer bar 16 is circumferentially moved in either direction along
the frame members 12 and 14 towards the stationary spacer bar 18
and positioned adjacent thereto, which permits the frame members 12
and 14 to be swung in opposite directions due to the pivotal
connection of the spacer bars into substantial parallel alignment
with the spacer bars so as to provide a substantially flat
structure which can be easily stored or hung on the wall, requiring
a minimum of space.
Referring now to FIG. 2, the collapsible receptacle support 10 of
FIG. 1 can be selectively provided with a cover 26 which may have a
handle 28 to facilitate removal of the cover from the receptacle
support. The cover 26 is supported on top of the upper frame member
14 and has a shape such as to conform with the upper frame member
14 and which placed in position, protects the refuse receptacle 20
from above. If desired, the cover 26 could be hinged, as shown at
30, to the frame work of the receptacle support 10 preferrably at
the upper brace 22 which is welded to the upper frame member
14.
With reference to FIGS. 3 to 5, in this embodiment a cover 32 is
provided consisting of a flat disc adapted to be placed upon the
upper frame member 14 for securement thereto by means of a
plurality of spring clips 34, as shown in FIG. 5. The spring clips
34 are easily detachable to permit easy removal of the cover
32.
As likewise shown in FIG. 3, a bottom 36 can be provided for the
receptacle support 10 to be placed upon the lower frame member 12
for securement thereto by similar spring clips 34 as shown in the
attachment for the cover 32. Selectively, the bottom 36 may be
provided with caster wheels 38 to facilitate movement of the
receptacle support from one location to another.
From the foregoing description it will be evident, that the present
invention provides a relatively simple and inexpensive collapsible
support for a receptacle, particularly for refuse receptacles, such
as disposable garbage bags and the like, which is not subject to
damage when being emptied. Damage by corrosion due to exposure to
the atmosphere will be minimal and can be neglected if it occurs.
Wear and corrosion resistance will be considerably increased if the
frame work for the receptacle support is being fabricated from
plastic rods.
Although the present invention has been described with reference to
several preferred embodiments, it will be obvious to the men
skilled in the art to which the invention pertains, that structural
changes and variations may be made therein without departing from
the spirit and essential characteristic of the invention as defined
by the scope of the appended claims.
