1. Field of the Invention
The present invention generally relates to storage and/or transportation systems and, in particular, to trailers.
2. Description of Related Art
Conventional trailers are unpowered vehicles that may be pulled by a powered vehicle. Trailers are commonly used to transport various goods and materials. Trailers may be for personal use and may be used with powered vehicles with an appropriate hitch.
A common type of trailer is a utility trailer that may be used to haul a variety of different types of materials. Disadvantageously, some trailers may be difficult to use and/or awkward to store. In addition, some trailers may have relatively limited uses.
Another type of conventional device use to transport goods and materials is a wheelbarrow. Known wheelbarrows are small hand-propelled vehicles, usually with just one wheel, which are designed to be pushed and guided by a single person using two handles disposed towards the rear of the wheelbarrow.
Wheelbarrows are frequently designed to distribute the weight of its load between the wheel and the operator, which may allow heavier and bulkier loads to be moved. Wheelbarrows are commonly in the construction industry and in gardening. A conventional wheelbarrow typically has a capacity of approximately six cubic feet of material.
It is also known to construct wheelbarrows with two wheels, which may make the wheelbarrow more stable on level ground. The two wheels, however, may make the wheelbarrow more difficult to use in certain circumstances. The two wheels may also make the wheelbarrow more difficult to load and unload, especially if the contents are being dumped out of the wheelbarrow.
A need therefore exists for a trailer that eliminates or diminishes the disadvantages and problems described above.
One aspect is a trailer that may include a connection assembly which is sized and configured to be connected to a vehicle to allow the vehicle to tow the trailer. For example, the connection assembly may include an arm or tongue that is sized and configured to be connected to the vehicle.
Another aspect is a trailer that may include a connection assembly which may be moved between an extended position and a retracted position. Desirably, when in the extended position, the connection assembly may be readily connected to a towing vehicle, and when in the retracted position, the connection assembly may be more compact, thus facilitating more efficient storage of the trailer. When the connection assembly is in the retracted position, a portion of the connection assembly, such as a foot, may be positioned to contact, abut and/or engage a support surface, such as the ground, which may advantageously help stabilize the trailer. Significantly, with a portion of the connection assembly contacting, abutting and/or engaging the support surface, the trailer may be used for other purposes. In particular, the trailer may include a handle, which may allow the trailer to be used as a wheelbarrow in such instances.
A further aspect is a trailer that may include a connection assembly with a first member and a second member. The first member may be connected to an axle, a container and/or other portions of the trailer. The second member may be sized and configured to be connected to a vehicle to allow the vehicle to tow the trailer. Desirably, the first and second members may be movably interconnected to allow the second member and/or the connection assembly to move between an extended position and a retracted position. A foot may be connected to, or form part of, the second member and may contact, abut and/or engage a support surface when the second member and/or the connection assembly are in the retracted position.
Another further aspect is a trailer that may include a connection assembly which is sized and configured to be selectively locked in the extended position and/or in the retracted position. For example, the connection assembly may include a first member, a second member and a foot. To lock the connection assembly in the extended position, a fastener (such as a locking pin) may be inserted through openings formed in the first and second members to secure them in a generally fixed relative position. Also, to lock the connection assembly in the extended position, a fastener may be inserted through openings formed in the first member and the foot to secure them in a generally fixed relative position. In addition, to lock the connection assembly in the retracted position, a fastener may be inserted through openings formed in the second member and a retaining member to secure them in a generally fixed relative position. The retaining member may be connected to, for example, a container and/or other portions of the trailer.
Yet another further aspect is a trailer that may include a connection assembly and a handle assembly. The connection assembly may include a towing arm that may be sized and configured to move between extended and retracted positions. The handle assembly may be movably connected to the towing arm, which may help the handle assembly move between extended and retracted positions relative to the towing arm. Significantly, when the towing arm is extended and the handle assembly is retracted, the trailer may be easily towed by vehicle. In addition, when the towing arm is retracted and the handle assembly is extended, the trailer may be used as a wheelbarrow.
A further aspect is a trailer that may include a connection assembly, handle assembly, and/or other components with openings that may be aligned to receive fasteners to secure the towing arm and/or the handle assembly in the extended and/or retracted positions. For example, the connection assembly may include a first set of openings and a second set of openings, and the handle assembly may include a set of openings that may be aligned with the connection assembly's first set of openings when the handle assembly is retracted and aligned with the connection assembly's second set of openings when the handle assembly is extended. The trailer may also include a retaining member with a set of openings that may be aligned with the connection assembly's first set of openings when the handle assembly is extended and the towing arm is retracted. In addition, the connection assembly may include first and second members with openings that may be aligned when the towing arm is extended and the handle assembly is retracted.
Still another aspect is a trailer that may include a container which is sized and configured to be moved among a plurality of positions. For example, the container may be moved from a carrying position in which contents remain in the container and a dumping position in which the contents are dumped out of the container. The container may be sized and configured to be selectively locked in the carrying position. For example, the trailer may include a locking mechanism. The locking mechanism may include a first bracket that may be connected to the container, a second bracket that may be connected to a connection assembly, and a latch that may move between a locked position and an unlocked position. When the latch is in the locked position, the latch may engage a portion of the first and second brackets to lock the container in the carrying position. When the latch is in the unlocked position, the latch may disengage the first and second brackets to allow the container to be freely moved between the carrying position and the dumping position. If desired, the latch may be biased towards the locked position and/or away from the unlocked position using a spring and/or other biasing members. Significantly, this may allow the locking mechanism to automatically lock when the container is moved to the carrying position. If desired, the latch may be positioned above and/or apart from the connection assembly, which may help provide a simpler and/or stronger design for the connection assembly.
Another aspect is a trailer that may include a container. For example, the trailer may include a tub or other type of container. The container may be constructed from molded plastic and may include one or more features integrally formed in the container during the molding process. For instance, the container may include one or more cup holders or trays integrally formed in the container during the molding process. The container may also include one or more handles integrally formed in the container during the molding process. The handles may, for example, be disposed in an under portion a lip of the container, may extend outwardly away from the body of the container and/or may have other suitable configurations and positions. In addition, the container may include one or more tool holders integrally formed in the container during the molding process. The tool holders may include receiving portions sized and configured to receive and/or retain at least a portion of one or more tools, such as rakes, brooms, shovels, hammers and/or other tools. The receiving portions may be sized and configured to receive and/or retain at least a portion of one or more tools using a snap, friction and/or interference fit. In some instances, the receiving portions may include recesses, passageways and/or openings into which portions of the tools may be inserted to help retain the tool and/or allow the tools to hang from the receiving portions. The container may be constructed using a blow molding process, an injection molding process and/or any other molding process.

As shown in
As shown in
Desirably, when the connection assembly 12 is in the retracted position, a portion of the connection assembly, such as a foot 16, may be positioned to contact, abut and/or engage a support surface, such as the ground, which may advantageously help stabilize the trailer 10. Significantly, with a portion of the connection assembly 12 contacting, abutting and/or engaging the support surface, the trailer 10 may be used for other purposes. In particular, the trailer may include a handle assembly 18, which may allow the trailer 10 to be used a wheelbarrow in such instances.
In further detail, the connection assembly 12 may include a first member 20 and a second member 22. The first member 20 may be connected to an axle 24, a container 26 and/or other portions of the trailer 10. The second member 22 may include the towing arm 14 and the foot 16.
The first and second members 20, 22 may be movably interconnected to allow the towing arm 14 and the foot 16 to move between extended and retracted positions. For example, the first and second members 20, 22 may be pivotally interconnected using a fastener 28, which may allow the towing arm 14 to pivot between the extended and retracted positions. As shown in
The towing arm 14 and the foot 16 may be sized and configured to be selectively locked in the extended and/or retracted positions. For example, the first and second members 20, 22 and/or other components of the trailer 10 may include openings sized and configured to receive fasteners to selectively lock the towing arm 14 and the foot 16 in the extended and/or retracted positions.
In further detail, the first and second members 20, 22 may include openings 30, 32 shown in
As shown in
The handle assembly 18 may be sized and configured to be selectively locked in the extended and/or retracted positions. For example, connection assembly 12 and the handle assembly 18 may include openings sized and configured to receive fasteners to selectively lock handle assembly 18 in the extended and/or retracted positions. In greater detail, the second member 22 of the connection assembly 12 may include one or more openings 54 shown in
As shown in
Thus, as shown above, the connection assembly 12 may include a first set of openings 40 and a second set of openings 54, and the handle assembly 18 may include a set of openings that may be aligned with the first set of openings when the handle assembly is retracted and aligned with the second set of openings when the handle assembly is extended. In addition, the retaining member 36 may include a set of openings 38 that may be aligned with the first set of openings 40 when the towing arm 14 is retracted and the foot 16 and handle assembly 18 are extended. In addition, the first and second members 20, 22 of the connection assembly 12 may include openings 30, 32 that may be aligned when the towing arm 14 is extended and the foot 16 and handle assembly 18 are retracted.
Significantly, as discussed above, these aligned openings may receive fasteners (such as the fasteners 34, 42, 56, 58) to selectively secure the towing arm 14, the foot 16 and/or the handle assembly 18 in extended and/or retracted positions. In some embodiments, fasteners may be sized and configured to be interchangeably inserted into and received by these aligned openings. Accordingly, four fasteners 34, 42, 56, 58 are not required and merely two fasteners could be interchangeably received by the aligned openings. It will be appreciated, however, that the aligned openings and fasteners are not required and that the towing arm 14, the foot 16 and/or the handle assembly 18 may be selectively locked in extended and retracted positions using any other suitable means.
Accordingly, as shown in
In some embodiments, the container 26 may be sized and configured to be moved among a plurality of positions. For example, the container 26 may be moved from a carrying position in which contents remain in the container and a dumping position in which the contents are dumped out of the container. The container may be sized and configured to be selectively locked in the carrying position. For example, as shown in
When the latch 74 is in the locked position, the latch may engage a portion of the brackets 70, 72 to lock the container in the carrying position. For example, the latch 74 may comprise a link and, to lock the container in the carrying position, the link may include a receiving portion (such as a notch) that may be sized and configured receive, retain and/or engage a portion of the bracket 70 and a portion of the bracket 72. When the latch 74 is in the unlocked position, the latch may disengage the brackets 70, 72 to allow the container to be freely moved between the carrying position and the dumping position. If desired, the latch 74 may be biased towards the locked position and/or away from the unlocked position using a spring and/or other types of biasing members. Significantly, this may allow the locking mechanism 68 to automatically lock when the container 26 is moved to the carrying position. If desired, the latch 74 may be positioned above and/or apart from the connection assembly 12, which may help provide a simpler and/or stronger design for the connection assembly. It will be appreciated, however, that the latch 74 may be positioned in other suitable locations and need not be biased. It will also be appreciated that the locking mechanism 68 need not be automatic and may include a variety of other components, if desired.
