Device for moving large containers

Abstract

Devices and methods of using such devices to move containers are disclosed herein. A device may include a first piece with a wheel adjacent one end and a second piece attached to the first piece at a pivotal connection. The second piece may include a lift portion on one side of the pivotal connection and a handle on an opposite side of the pivotal connection. The handle may be adapted to be pivoted about an axis of the pivotal connection to cause the lift portion to lift a portion of the container.

Description

BACKGROUND

Some large containers include wheels or other similar mechanisms to aid with movement. For example, large garbage or recycling containers often include two wheels on one side and a lift bar or handle or other similar means on the opposite side. At rest, the side without the wheels sits on the ground and prevents the container from moving. When the container is to be moved, the lift bar can be used to lift the side opposite the wheels off the ground, so that the side with wheels can be rolled to move the container between locations. Some such containers are referred to as “toter-style” trashcans.

A “toter-style” trashcan tends to become heavy when it is filled with debris, which makes it difficult to lift the side opposite the wheels so that the trashcan may be moved. People with disabilities, particularly those that are wheelchair-bound, may be unable to lift the side of the trashcan opposite the wheels.

DETAILED DESCRIPTION

This disclosure provides examples of devices for moving large containers. Many alternatives and modifications, which may or may not be expressly mentioned, are enabled, implied, and accordingly covered by the spirit of the disclosure. Although trashcans and “toter-style” trashcans are mentioned repeatedly herein, it should be understood that other large containers may be moved with devices described herein.

FIGS. 1 and 2 depict an exemplary device 10 sitting adjacent a container in the form of a standard “toter-style” trashcan 12. “Toter-style” trashcan 12 includes on one side 14 one or more wheels 16 and on the other side 18 a recess 20 in which a lift bar 22 is mounted. Lift bar 22 may be used to lift side 18 of trashcan 12 opposite wheels 16 off the ground so that trashcan 12 may be moved between locations.

Device 10 includes a first piece 24 with a planar portion 26 having a wheel mounted 28 at one side 30 and one or more press members 32 on the other side 34. Wheel 28 may be a caster wheel that is configured to swivel on a plane parallel to that of planar portion 26. Planar portion 26 is shaped on one side 36 to fit within recess 20 of a standard “toter-style” trashcan 12. Press members 32 may be elongate bars forming a portion of first piece 24 that are curved at the end of first piece 24 opposite planer portion 26 so that the ends will contact a side 38 of a container such as trashcan 10, as will be explained further below. Although device 10 of FIG. 1 includes two press members 32 that are curved relative to first piece 24, it should be understood that other numbers of press members, including only one, may be utilized. Additionally, while press members 32 are shown as being curved away from first piece 24, in some embodiments, press members 32 are not curved away from first piece 24.

A second piece 40 is attached to first piece 24 at a pivotal connection 42 that allows the two pieces to pivot about an axis 44. Second piece 40 includes on a first end 46 a lift portion 48 that is curved away from the rest of second piece 40. A handle 50 is provided at a second end 52 of second piece 40 opposite lift portion 48. In this non-limiting example, second piece 40 is constructed with an elongate bar 54, and handle 50 is a 180-degrees curved portion 56 of elongate bar 54. Parallel portions 58 of elongate bar 54 that extend between handle 50 and lift portion 48 are separated from each other by a distance 60 that is greater than a distance between outermost surfaces of press members 32, so that press members 32 fit between. The opposite may be true in some embodiments, and in yet other embodiments where only one press member is present, a different configuration may be implemented. In some embodiments, a separate handle connects two separate bars that form second piece 40.

FIGS. 3-5 depict an example of how first piece 24 and second piece 40 may pivot about axis 44 (indicated in FIGS. 1 and 2) relative to one another to function as a “claw” that grabs lift bar 22 of “toter-style” trashcan 12. In FIG. 3, the first and second pieces have not yet been pivoted about axis 44. Device 10 in this configuration may be tilted as shown in FIG. 3 so that it can be maneuvered easily between locations (e.g., towards a target trashcan).

Once the device is maneuvered so that lift bar 22 of “toter-style” trashcan 12 is in between press members 32 and lift portion 48, as shown in FIG. 4, device 10 may be manipulated so that press members 32 and lift portion 48 “clamp” onto lift bar 22, as shown in FIGS. 2 and 5. The beginning of this manipulation is shown In the middle of FIG. 4, where handle 50 has been pivoted downwards slightly (as indicated by the arrow) so that lift portion 48 has pivoted upwards (opposing gravity). Meanwhile, press members 32 have moved slightly to the left. In FIG. 5, handle 50 has been pivoted down further so that lift portion 48 on second piece 40 is moved further upwards and press members 32 on first piece 24 are moved towards the left. With this pivoting motion, lift portion 48 and press members 32 operate together like a claw to grip lift bar 22.

This simultaneous engagement is best seen in FIGS. 2 and 5. A downward force applied to handle 50 (as shown by the arrow in FIG. 4) imparts an opposite upward force on lift portion 48, by virtue of pivotal connection 42 of first piece 24 and second piece 40. Since lift portion 48 is curved, the overall force applied by lift portion 48 to lift bar 22 is at an angle relative to the ground. In other words, the force has a vertical component, which lifts trashcan 12 off the ground, and a horizontal component, which imparts force on lift bar 22 in a direction away from the surface (i.e., side 38) of trashcan 12. Accordingly, the horizontal component of the total force applied to lift bar 22 by lift portion 48 may be opposed by an equal and opposite force applied by lift bar 22 on lift portion 48 in a direction towards trashcan 12. This equal and opposite force may be exerted on first piece 24 to help secure planar portion 26 of first piece 24 within recess 20 of trashcan 12. As best seen in FIGS. 1 and 2, one end 36 of planar portion 26 is shaped to engage recess 20 of trashcan 12 to prevent lateral movement of device 10 along the side of trashcan 12.

Some embodiments may include mechanisms for preventing lift portion 48 and press member 32 from pivoting away from each other beyond a predetermined angle. For example, device 10 in FIGS. 1 and 2 includes a stop bar 62 with a longitudinal axis that is parallel to axis 44 of pivotal connection 42. Stop bar 62 in FIG. 2 is located on second piece 40 in between parallel portions 58 of elongate bar 54 adjacent pivotal connection 42. If handle 50 is pivoted downwards far enough, and hence lift portion 48 and press members 32 are pivoted away from each other to a particular predetermined angle, stop bar 62 will contact first piece 24, preventing further pivoting.

Devices according to the present disclosure may be constructed using any number of materials. In exemplary embodiments, the device is constructed from steel. In other embodiments, the device may be constructed from aluminum. Moreover, while the embodiments described above are manipulated using manual power (i.e., an individual pivots the handle down manually), embodiments that use electro-mechanical power or hydraulics to assist in lifting the container are also contemplated herein.

It is believed that the disclosure set forth above encompasses distinct embodiments with independent utility. While each of these embodiments has been disclosed in its preferred form, the specific embodiments as disclosed and illustrated herein are not to be considered in a limiting sense as numerous variations are possible.

The subject matter of the disclosure includes all novel and non-obvious combinations and subcombinations of the various elements, features, functions and/or properties disclosed herein. Similarly, where the disclosure recites “a” or “a first” element or the equivalent thereof, such disclosure should be understood to include incorporation of one or more such elements, neither requiring nor excluding two or more such elements. Novel and non-obvious combinations and subcombinations of features, functions, elements and/or properties may be claimed through presentation of claims in a related application.
