Portable bag holder employing elastic bands
Abstract
A device for holding a collapsible bag, such as a plastic trash
bag, in an open and operable position. A rim supports the mouth of
the bag, while a handle and forearm brace permit a user to hold it
easily and without fatigue. The handle and brace are placed at the
edge of the rim so as to leave the opening unobstructed and
maximize versatility for both trash and leaf pickup.

BACKGROUND
[0005] The present application relates to trash containers, and in
particular relates to portable containers to facilitate the
collection of trash and debris found on the ground.
[0006] Trash and other debris such as leaves falling from trees in
autumn are frequently found scattered on the ground and in need of
collection. Existing devices have a number of problems. Trash bags
alone are floppy and do not stay open readily, frequently requiring
two hands to hold them open. This does not leave a hand free to
collect the item to be placed in the bag. Trashcans, although
rigid, are bulky and cumbersome to move when collecting debris over
a wide area, as along a highway. They are also difficult to
transport and store.
[0007] Some portable solutions for this problem exist. For
instance, both Langley (U.S. Pat. No. 5,997,061) and Passage (U.S.
Pat. Pub. No. 2004/0195467) disclose a bag holder for facilitating
collection of trash and leaves which can hold a bag open and
provide a handle for a user.
[0008] However, users of these designs are likely to suffer
considerable fatigue if they must carry them for long periods. The
handle is located on one edge of the trash bag, and the result of
this design is that entire torque exerted on the handle by the
weight of the trash is borne by the wrist of the user. As the bag
fills, it gets heavier and causes fatigue in muscles not adapted to
holding heavy loads.
[0009] Moe (U.S. Pat. No. 5,217,271) shows a bag secured to a frame
by elastic, the frame having two holes to accept trash and a handle
between the holes to facilitate transportation. This design does
not suffer from the torque problem, because the handle is
horizontal and near the likely balance point for the trash in the
bag. However, the openings of the Moe design, while adequate for
picking up small pieces of trash in a park or on a highway, are
poorly placed and too small to permit a user to easily rake or
scoop large quantities of debris, such as autumn leaves.
[0010] What is needed, then, is a holder for a trash bag which is
both comfortable for a user to hold for extended periods and
versatile enough to be used for a variety of trash-removal
operations.
SUMMARY
[0011] The present disclosure answers some of the shortcomings of
the prior art by providing a trash bag holder with both a handle
and a forearm support, allowing it to be carried for long periods
when picking up trash, but leaving the mouth of the bag
unobstructed for easy raking of large quantities when
necessary.
[0012] The holder has a large hoop-like rim, which may have a
channel on its outer perimeter. A bag may be secured to the rim
quickly using an elastic band, which holds the bag in the channel.
A handle attached to the edge of the rim allows for easy handling
and control. A forearm support extends from the rim near the handle
and passes under the forearm of the user, thus providing a
counterbalance to the weight of the trash collected in the bag and
allowing for easy long-term use. Because the handle is placed on
the perimeter of the bag, a portion of the rim may be placed
vertically on the ground to allow leaves to be swept into the bag
in bulk.
[0013] The foregoing and other objectives, features, and advantages
will be more readily understood upon consideration of the following
detailed description taken in conjunction with the accompanying
drawings.

DETAILED DESCRIPTION OF EMBODIMENTS
[0019] Referring now to the drawings, FIG. 1 depicts a bag holder
10 with a trash bag 12 attached. The bag is secured by a loop of
elastic material 14, for example rubber surgical tubing, placed in
a channel 16 and extending along the perimeter of a hoop 18, as
best shown in FIG. 2. The bag 12 may be composed of any pliable
material, but is most commonly a thin plastic garbage bag, widely
available for home and office use. The bag holder 10 may be
composed of any suitably sturdy and rigid material or combination
of materials, such as hard plastic, fiberglass, or metal, provided
the material is both strong enough to bear the weight of the trash
in the bag 12 and lightweight enough to be easily portable. In an
exemplary embodiment, it is composed of aluminum. Attached to the
hoop 18 is a plate 20, which serves as an attachment point for all
elements of the bag holder 10. A handle 22 is attached to the plate
20 and angled for a comfortable and ergonomic grip. A conventional
pistol-type grip is preferable because it does not require the
user's wrist to bend when gripped. A forearm brace 24 extends from
the plate 20 away from the hoop 18 and downward, to engage the
underside of the forearm 26 of a user holding the handle 22, as
best shown in FIG. 4.
[0020] The brace 24 acts as a cantilever to weight in the trash bag
12. The brace 24 may be formed of a loop of aluminum or other
strong but lightweight material. The user's wrist is inserted
through the loop in order to grip the handle 22. The user's hand
then becomes a fulcrum with leverage provided by the brace 24
bearing against the underside of the user's forearm, all while the
hand grips the handle in a comfortable position, that is without
any bend in the wrist. This allows the forearm to bear the weight
in the bag and takes pressure off the wrist. The downward
displacement of brace 24 is selected to assure an approximately
level bag mouth 27 when the user grips the handle 22 in a
conventional manner.
[0021] FIG. 3 shows the loop of elastic 14 removed from the channel
16. The loop of elastic 14 may so sized as to require some degree
of stretching when at rest in the channel 16, to provide adequate
frictional grip on the bag 12. The cross-sectional diameter 15 loop
of elastic 14 may also be so sized as to be slightly larger than
the width 17 of the channel 16, so as to deform and exert a slight
outward force to improve the retention of bag 12. The loop of
elastic 14 is may be attached to the bag holder 10 by any method,
such as gluing, clamping, or tying. In an exemplary embodiment, the
loop of elastic 14 is composed of hollow surgical tubing, and is
secured by inserting the hollow center 30 of the tubing onto
pivoting retaining pins 28. The pins 28 are so sized as to require
the tubing to expand slightly and thus retain the tubing by
friction. The pins 28 pivot about an axis 32 which is perpendicular
to the rim so as to facilitate both attachment and removal of the
bag 12 and replacement of the loop of elastic 14 should it become
worn or damaged.
[0022] The handle 22 and brace 24 may be covered in a suitable
elastomeric material to provide cushioning and/or temperature
insulation.
[0023] The terms and expressions which have been employed in the
foregoing specification are used therein as terms of description
and not of limitation, and there is no intention in the use of such
terms and expressions of excluding equivalents of the features
shown and described or portions thereof, it being recognized that
the scope of the invention is defined and limited only by the
claims which follow.
