Description
This invention relates to a portable bag holder such as may be
utilized for example for holding a flexible garbage bag with its
opening spread apart in such orientation as to facilitate the
loading of refuse therethrough and into the interior of the
bag.
Various devices for spreading the openings of bags and sacks are
known in the prior art but many of these devices have been
specifically designed to fulfill a required function in a fixed
orientation; for example, for spreading the opening of a sack to
receive grain from a hopper wherein the sack is retained in a
vertical position with its opening uppermost.
It is one object of the present invention to provide a portable bag
holder which is capable of holding a bag thereon with its mouth
spread open and which is readily maneuverable to orientate the bag
into whichever position is most convenient to the person filling
the bag.
Other objects of the invention include the provision of such a bag
holder which is economical to manufacture; which is designed to
permit rapid and simple mounting and de-mounting of a bag thereon;
which includes means for firmly retaining a bag in mounted position
thereon with its mouth spread open and tensioned to take up slack
and which includes means facilitating the ready and direct loading
of materials into the bag without undue spillage.
In accordance with the invention the subject portable bag holder is
comprised of spaced apart support portions for engaging
corresponding parts of the edges of the mouth of the bag; means for
tensioning the mouth of the bag about said support portions; an
elongated lip facilitating passage of materials thereover and into
the bag and a handle for orienting the bag in a cleared
position.
Other features of the invention will becomes apparent from the
following description thereof given herein solely by way of example
with reference to the accompanying drawings wherein like reference
numerals refer to the like parts therethrough the several views and
wherein:
FIG. 1 is a front and top perspective view of one form of the
subject bag holder with a bag mounted thereon:
FIG. 2 is a view similar to that of FIG. 1 but with the bag
removed;
FIG. 3 is an enlarged exploded view of the tensioning means;
FIG. 4 is a side cross-sectional view of the bag holder;
FIG. 5 is a front and top perspective view of a further embodiment
of subject bag holder;
FIG. 6 is an enlarged perspective view of the tensioning means of
the FIG. 5 bag holder;
FIG. 7 is a front and top perspective view of a yet further
embodiment of the bag holder;
FIG. 8 is a front and top perspective view of a still further
embodiment;
FIG. 9 is a front and top perspective view of another
embodiment;
FIG. 10 is a front perspective view of a further embodiment;
and
FIG. 11 is an enlarged perspective view from the rear of the
tensioning means employed in the embodiment of FIG. 10.
The subject bag holder is comprised essentially of support portions
10 and 12 upon which the mouth or opening of a bag B is engageable;
means 14 for tensioning the bag opening about the support portions
10 and 12; an elongated lip 16 for facilitating passage of
materials thereover through the bag opening and into the interior
thereof and a handle 18 for maneuvering the bag B into a desired
position and orientation.
Referring first of all to the embodiment shown in FIGS. 1 through 4
of the drawings it will be noted that the support portions 10 and
12 are constituted as an upper support portion 10 adjacent the
handle 18 and a lower support portion in spaced opposed relation
thereto.
In this embodiment said upper and lower support portions 10 and 12
are relatively spread apart by the tensioning means 14 as will be
further described herein.
The bag holder further includes a peripheral wire frame having
upper convergent frame elements 20, parallel side elements 22 and a
lower element constituting the lower support portion 12. The lip 16
which is of flat plate like form is co-extensive with said lower
support portion 12, and is fixedly secured to the frame side
elements 22, as by welding for example, to project forwardly
therefrom in a direction inclined away from the handle 18.
The upper frame elements 20 are bent at their position of
convergence into a pair of parallel members 24, the upper parts of
which constitute the handle 18.
The upper support portion 10 is comprised of a plate-like member
having convergent fins 26, the angle of convergence of which
corresponds to that of the upper frame elements 20, and which is
mounted for sliding movement upon the parallel members 24. The
tensioning means acts to resiliently bias the fins 26 away from the
upper frame elements 20 and the lower support portion 12.
The construction of the upper support portion 10 and the tensioning
means 14 is shown in greater detail in FIGS. 3 and 4 wherein it
will be seen that the tensioning means is comprised of a coil
tension spring acting between the handle 18 and the fins 26 to bias
them as foresaid. More specifically the fins 26 include a centre
platform 28 secured as by screws 30 to an L-shaped bracket 32
having one arm parallel to the members 24 and to which one end of
the spring is attached. The assembly also includes front and back
plates 34 and 36 respectively secured together as by bolt 38 and
spacer 40 to retain the fins 26 in position for sliding movement
upon the members 24.
The bag holder assembly is conveniently completed by a sleeve 42,
of plastic for example, placed over the upper ends of the members
24 and providing a convenient grip for the handle 18.
It may be noted at this juncture that the construction of the bag
holder hereinbefore described is extremely simple and the materials
thereof may be chosen to provide an extremely lightweight article
when assembled.
In this embodiment, it is contemplated that the bag holder may be
utilized to mount a garbage bag B thereon of the well-known plastic
variety which may thereafter conveniently be utilized to receive
garden refuse swept directly thereinto off the ground.
To mount the bag on the holder, the bag opening is spread by hand
and placed around the peripheral frame and over the fins 26 which
are depressed by hand adjacent the bias of the coil spring. As
illustrated in FIG. 1, the bag opening is placed wholly around the
peripheral frame so that all of the frame elements are located
inward of the edges of the bag opening with the lip 16 thus
extending from the inside to the outside of the bag opening.
Release of the fins 26 will permit them to move upwardly under the
influence of the coil spring thereby tensioning the edges of the
bag opening about those elements of the holder which engage the
said opening so that no slack is left therearound.
When the bag is mounted as aforesaid, and as illustrated in FIG. 1,
the user may then orientate the bag to its required position by
picking up the whole assembly of holder and bag by the handle 18.
In particular, when used for the reception of refuse off the
ground, the holder may be positioned so that the forward edge of
lip 16 is on the ground whereby refuse may be swept directly into
the bag without any undue spillage thereon.
It will, of course, be evident that the subject bag holder will
permit equally easy demounting of a bag therefrom and that it is
adaptable to mount bags of differing mouth diameter in the tensed
condition as aforesaid subject only to the dimensions of the
peripheral frame and the degree of relative movement which is
permitted between the upper and lower support portions 10 and
12.
Turning now to the embodiment illustrated in FIGS. 5 and 6 there is
shown a somewhat similar bag holder to that aforedescribed with the
difference that there is no provision for relative movement between
the support portions thereof; the tensioning of the bag opening
being accomplished by a rotary device as will be further
described.
In this embodiment, the holder again includes a peripheral wire
frame having convergent upper frame elements 20 which however
actually constitute the upper support portion 10. The side frame
elements 22 are relative to the upper elements 20 and have lower
ends directly attached to opposite ends respectively of the lip 16.
Said lip 16 has a rear flange bent out of the plane of the
remainder of the lip and which constitutes the lower support
portion 12 of the holder.
At the lower ends of the members 24 there is provided a fixed block
44 providing a plain bearing for a threaded shaft 46 of the rotary
tensioner 14. Such tensioner also includes a tongue in the form of
a pair of parallel fingers 48 fixedly secured on diametrically
opposed sides of shaft 46 and extending rearwardly of the handle
18.
The other end of shaft 46 extends through the block 44 and is
provided with a knob 50 for facilitating rotation thereof. A wing
nut 52 threadedly mounted on the shaft 46 between the block 44 and
knob 50 serves as a locking means to bind against the block and
lock shaft 46 in a desired angular orientation. It will, of course,
be understood that any suitable fastening means may be
employed.
In use, the dilated opening of the bag, which may or may not be
folded at the option of the user, is drawn over the peripheral
frame elements including the upper and lower support portions 10
and 12 and an edge of the bag opening is between the fingers 48 of
the tensioning means 14. Rotation of the shaft 46 by means of knob
50 will thus furl the edge of the bag opening about the fingers 48
contracting the bag opening and tensioning it about the support
portions of the holder. When the bag opening is suitably tensioned
as aforesaid, the lock nut 52 is rotated to bind against block 44
thereby locking the shaft 46 in position and retaining the bag
opening in its tensed condition.
FIG. 7 illustrates a somewhat simplified embodiment of the subject
bag holder being comprised of a straight side frame element 22 and
a lower frame element constituting the lower support portion 12
carrying the lip 16 co-extensively thereon.
The upper support portion 10 is constituted by a single flanged bar
54 slidably mounted at its one end by a collar 56 upon the frame
element 22 and lockable in position thereon by a thumb screw or the
like 58. In this embodiment, said bar 54 also constitutes the
tensioning means and, in use, the bag opening is placed over the
bar 54, around frame element 22 and under lower support portion 12;
upward movement of the bar 54 relative to portion 12 thus
tensioning the bag opening about the support portions.
FIG. 8 illustrates an even more simplified embodiment which is
really only adapted to mount one particular size of bag opening
thereon. This bag holder is comprised of a partial peripheral frame
having upper frame element 20, side frame element 22 and a lower
frame base element constituting the lower support portion 12.
The lip 16 is co-extensive with and fixedly secured to said lower
support portion 12.
The upper support portion 10 is provided by a flange 60 fixedly
secured to upper frame element 22 and curved therewith as
illustrated. In this embodiment, the side frame element 22 at least
is formed of a resilient material such as spring steel and
constitutes tensioning means resiliently biassing upper and lower
support portions 10 and 12 away from another.
It will be apparent that, in use, the opening of a bag is placed
around the support portions 10 and 12 and frame element 22 whilst
the latter is deformed to permit such placement. Subsequent release
will permit the resilience of element 22 to bias the support
portions 10 and 12 away from one another tensioning the bag opening
as desired.
The embodiment of FIG. 9 is basically similar to that shown in FIG.
7 except that a partial peripheral frame is provided affording a
side frame element 22 and simple member 24 which itself affords a
bearing for a pair of opposed slidable bars 54 constituting both
the upper support portion 10 and the tensioning means as described
with respect to the FIG. 7 embodiment.
In the embodiments shown FIGS. 10 and 11 support for the upper bag
edge is provided by the tensioning means 48 which engages the bag
edge and upon rotation holds the bag taut over frame portion 60.
The upper frame element 20 through its form prevents rakes and
brooms or the like from making contact with the edge of the
bag.
