Embodiments of the invention relate generally to the transportation of objects/cargo, and more specifically, to an apparatus for transporting an object.
Many modern manufacturing facilities, e.g., warehouses and/or other types of industrial/commercial/research facilities, often have loading docks to facilitate the movement of goods/cargo from the facility to a wheeled trailer, also referred to herein simply as a “trailer”, or vice versa. Many loading docks are configured such that the walkway/bridge of the dock is nearly level with the floor of a trailer, e.g., the loading dock may have a recessed ramp which the wheeled trailer is backed down so that when the open end of the trailer is flush against the edge of the dock, the floor of the trailer is nearly level with the walkway of the dock. When the walkway/bridge of the dock is nearly level with the floor of a trailer, goods/cargo can be easily transferred from the facility to the wheeled trailer via a standard dolly, pallet jack, and/or forklift.
While such loading docks provide for an efficient means of transferring goods between a trailer and a facility, the recessed ramps of such docks often prove problematic for moving goods in and/or out of the encompassing facility in the absence of a trailer. In other words, it is usually very difficult to efficiently move goods/packages between the lower elevation pavement and the higher elevation of the bridge/walkway. While many traditional devices, such as forklifts, cranes, and lift platforms, are capable of moving good/packages between different elevations, the bodies of many such traditional devices, e.g., small cranes, often have one or more stabilizers, e.g., outriggers, that protrude from the front, i.e., the side of the main body configured to face the loading dock. Such forward facing stabilizers, however, often limit how close the main body of such traditional devices can be positioned with respect to the loading dock. Thus, many traditional devices require an operator to load/unload the cargo from/onto the bridge of a dock with the main body at a distance from the dock. Loading/unloading cargo from/onto a dock in such a manner, however, is often a slow, difficult, and/or dangerous process, as the operator of such a traditional device must take care to ensure that the center of gravity of the device, when loaded with cargo, does not shift to a point such that the device tips over.
What is needed, therefore, is an improved apparatus and method for transporting an object between two elevations, e.g., a loading dock/upper shelf and trailer/lower shelf.
In an embodiment, an apparatus for transporting an object is provided. The apparatus includes a mast and a carriage. The mast transitions between a first position defined by a first angle of incidence of the mast with a surface that supports the mast, and a second position defined by a second angle of incidence of the mast with the surface. The carriage traverses the mast and has one or more connectors that selectively secure the object to the carriage. The mast and the carriage are operative to transport the object along the surface when the mast is in the first position, and to facilitate engagement and disengagement of the one or more connectors with the object when the mast is in the second position.
In another embodiment, a method for transporting an object is provided. The method includes transitioning a mast of an apparatus from a first position defined by a first angle of incidence of the mast with a surface that supports the mast, to a second position defined by a second angle of incidence of the mast with the surface. The method further includes engaging one or more connectors of a carriage, that traverses the mast, to the object; transitioning the mast from the second position to the first position and selectively securing the object to the carriage via the one or more connectors; and transporting the object along the surface via the mast and the carriage.
In yet another embodiment, an apparatus for transporting an object is provided. The apparatus includes a mast, a winch, and a carriage. The mast transitions between a first position defined by a first angle of incidence of the mast with a surface that supports the mast, and a second position defined by a second angle of incidence of the mast with the surface. The winch includes an elongated flexible member. The carriage is selectively connectable to the elongated member so as to traverse the mast via the winch, and has one or more connectors that selectively secure the object to the carriage. The mast and the carriage are operative to transport the object along the surface when the mast is in the first position, and to facilitate engagement and disengagement of the one or more connectors with the object when the mast is in the second position. The winch is operative to transport the object via the elongated member when the carriage is selectively disconnected from the elongated member and the mast is in the first position.

For example, the above-described embodiments (and/or aspects thereof) may be used in combination with each other. Additionally, many modifications may be made to adapt a particular situation or material to the teachings of the invention without departing from its scope.
For example, in an embodiment, an apparatus for transporting an object is provided. The apparatus includes a mast and a carriage. The mast transitions between a first position defined by a first angle of incidence of the mast with a surface that supports the mast, and a second position defined by a second angle of incidence of the mast with the surface. The carriage traverses the mast and has one or more connectors that selectively secure the object to the carriage. The mast and the carriage are operative to transport the object along the surface when the mast is in the first position, and to facilitate engagement and disengagement of the one or more connectors with the object when the mast is in the second position. In certain embodiments, the first angle of incidence is between about 10° to about 45°, and the second angle of incidence is between about −10° to about 10°. In certain embodiments, the mast transitions between the first position and the second position by pivoting about a point disposed on the surface. In certain embodiments, the apparatus further includes a tilting base disposed on the mast and operative to facilitate transition of the mast between the first position and the second position. In certain embodiments, the tilting base facilitate transition of the mast between the first position and the second position via pivoting about a point disposed on the surface. In certain embodiments, the tilting base is disposed on the mast so as to stabilize the mast and the carriage when the mast is in the first position. In certain embodiments, the tilting base includes a first handle and the mast includes a second handle, and the tilting base facilitates transition of the mast between the first position and the second position via at least one of the first and the second handles. In certain embodiments, the apparatus further includes a motor that facilitates traversal of the mast by the carriage. In certain embodiments, at least one of the one or more connectors is at least one of a fork, a hitch ball, a hook, a clamp, a platform, a platform, and a magnet. In certain embodiments, the apparatus further includes one or more caster wheels operative to facilitate transportation of the object via the mast and the carriage along the surface.
Yet other embodiments provide a method for transporting an object. The method includes transitioning a mast of an apparatus from a first position defined by a first angle of incidence of the mast with a surface that supports the mast, to a second position defined by a second angle of incidence of the mast with the surface. The method further includes engaging one or more connectors of a carriage, that traverses the mast, to the object; transitioning the mast from the second position to the first position and selectively securing the object to the carriage via the one or more connectors; and transporting the object along the surface via the mast and the carriage. In certain embodiments, the method further includes transitioning the mast from the first position to the second position and selectively unsecuring the object from the carriage via the one or more connectors. In certain embodiments, the method further includes selectively traversing the carriage along the mast while the object is secured to the carriage via the one or more connectors and while the mast is in the first position. In certain embodiments, the first angle of incidence is between about 10° to about 45°, and the second angle of incidence is between about −10° to about 10°. In certain embodiments, transitioning the mast from the first position to the second position, and transitioning the mast from the second position to the first position each include pivoting the mast about a point disposed on the surface. In certain embodiments, the apparatus further includes a tilting base disposed on the mast. In such embodiments, transitioning the mast from the first position to the second position, and transitioning the mast from the second position to the first position each include pivoting the tilting base about a point disposed on the surface. In certain embodiments, pivoting the tilting base about a point disposed on the surface is facilitated via a first handle disposed on the tilting base and a second handle disposed on the mast. In certain embodiments, the method further includes stabilizing the mast and the carriage via a tilting base when the mast is in the first position. In such embodiments, the tilting base is disposed on the mast. In certain embodiments, at least one of the one or more connectors is at least one of a fork, a hitch ball, a hook, a clamp, and a magnet.
Yet still other embodiments provide for an apparatus for transporting an object. The apparatus includes a mast, a winch, and a carriage. The mast transitions between a first position defined by a first angle of incidence of the mast with a surface that supports the mast, and a second position defined by a second angle of incidence of the mast with the surface. The winch includes an elongated flexible member. The carriage is selectively connectable to the elongated member so as to traverse the mast via the winch, and has one or more connectors that selectively secure the object to the carriage. The mast and the carriage are operative to transport the object along the surface when the mast is in the first position, and to facilitate engagement and disengagement of the one or more connectors with the object when the mast is in the second position. The winch is operative to transport the object via the elongated member when the carriage is selectively disconnected from the elongated member and the mast is in the first position.
Accordingly, by providing for a mast that transitions between two positions, as described above, wherein the mast engages a pallet in a rocked forward position while transporting the pallet in a tilted resting position, some embodiments of the present invention may provide for an apparatus for transporting pallets that, unlike traditional devices of moving pallets, does not require the use of forward facing outriggers for stability. Accordingly, some embodiments of the present invention may provide for an apparatus for transporting pallets that has a smaller form factor than traditional forklifts, which in turn, may makes such embodiments of the present invention lighter and/or easier to maneuver than traditional object moving devices. In particular, by not utilizing forward facing outriggers/supports, some embodiments of the present invention are able to be positioned closer to the wall of a loading dock than traditional object moving devices, which in turn, reduces the distance that the connectors, e.g., forks, have to be extended in order to engage and disengage a pallet. Thus, some embodiments of the present invention are safer to operate than traditional forklifts.
Further, by incorporating an electric motor, some embodiments of the present invention have a lower emissions rate than many traditional forklifts.
