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

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.

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.

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.

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.

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.

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

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.

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.

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

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.

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.

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.

The handle 22 and brace 24 may be covered in a suitable elastomeric material to provide cushioning and/or temperature insulation.
