20090261547 | Ross dolly trolley - The Ross Dolly Trolley is a modified hand truck or furniture cart. It is modified by adding four keel or thimble wheels (guide wheels) to the inside of the frame that will allow it to track the rails of an extension ladder. A pivot pin is inserted through the step of the ladder and tied down. It can then be used in conjunction with block and tackle to load and unload items into or out of a pickup truck, or other cargo vehicles. An extension ladder is pivotally mounted on a cargo bed of a truck, by inserting a pin through a step of the ladder. Each side of the pin is then strapped to the truck. A pulley system (block and tackle) is hooked to the top of the ladder as well as the loaded dolly, by pulling a rope through the pulleys, the dolly trolley will climb the ladder when it reaches a certain point the ladder will pivot, depositing the loaded dolly trolley into the truck. | 10-22-2009 |
20100084832 | VIBRATORY RAMMER TRANSPORT WHEEL ASSEMBLY - A wheel assembly for providing wheeled transport to a compaction tool having a foot structure. The wheel assembly comprises an axle support member comprising at least one attachment means for attaching the axle support member to a top surface of the foot structure. The assembly further comprises an axle removably attached to the axle support member and having first and second opposite ends. A first wheel is mounted on the first end of the axle and a second wheel is mounted on the second end of the axle. The axle support member is fitted on a pair of pre-existing nut-bolt fasteners on the top surface of the foot structure. | 04-08-2010 |
20100090427 | Monument transport tool and method - A transport tool is disclosed for moving an aircraft monument from one location to another. The transport tool comprises an elongated, substantially rectangular, support frame having handle members at an upper region, wheel elements at a lower region, and a leg pivoted to the mid-region of the tool for supporting a load mounted to the tool as the transport tool is rotated about the wheel elements from a vertical orientation in which the load can be loaded onto, or unloaded from, the tool to a horizontal orientation in which the load can be transported from one location to another. Also disclosed is a method for transporting the load between two locations using the transport tool. | 04-15-2010 |

20100156059 | TRANSPORTATION DEVICE - The present disclosure relates to a transporting device for transporting loads by hand with a base frame made of sheet metal or metal tubing in the manner of a hand truck, which has two transport wheels at a lower end opposite a loading shovel and in the center of the lower end, a support wheel in a first end position. The support wheel can be displaced along the longitudinal extension of the base frame into a second end position. | 06-24-2010 |
20100270763 | Wheeled apparatus having multiple wheelbase configurations - A wheeled apparatus has a pair of first-size wheels attached in a spaced apart arrangement to a main frame at its first end portion. A subframe is moveably attached at its first end portion to the main frame at a position between the first-size wheels and a second end portion of the main frame. The subframe is attached to the main frame for allowing the subframe to be freely moved between a first position and a second position. The subframe and the main frame jointly limit movement of the subframe to be between the first and second positions. A pair of second-size wheel is attached to a second end portion of the subframe. The first-size and second-size wheels jointly provide a first wheelbase length when the subframe is in the first position and jointly provide a second wheelbase length when the subframe is in the second position. | 10-28-2010 |
20110156366 | PORTABLE SHOOTING RAIL - A portable shooting rail for use with a tree stand includes a rear frame assembly for engaging a tree. The rear frame assembly has a pair of spaced rear arms for engaging a tree and a pair of spaced forward arms and a vertical support portion that extends upwardly from the arms for placement against the tree. The vertical support member has a bottom cross bar and a top cross bar. The forward arms extend outwardly from the vertical support portion such that an obtuse angle is formed between the forward arms. A pair of struts connects the top cross bar to the forward arms. The shooting rail also includes a rail structure that is detachably coupled to the rear frame, with the rail structure being formed of separate rail sections that attach to one another and to the rear frame assembly to define a completed loop. | 06-30-2011 |
20120126500 | STABILIZATION MECHANISM FOR LUGGAGE - A stabilization mechanism for luggage is provided. The stabilization mechanism can be disposed on the bottom of a compartment of luggage and in spaced relation to wheels that are also disposed on the bottom of the compartment. The stabilization includes at least one foot that is retractable within the compartment, so that in the retracted position the volume of the luggage is substantially the same as the luggage compartment. When the at least one foot is deployed, the likelihood of tipping of the luggage is decreased, as the foot, in conjunction with the wheels, maintain the luggage in a substantially vertical position. | 05-24-2012 |
