| 280482000 | Adjustable length draft devices | 9 |
| 20090160160 | Adjustable trailer for luggage carriers - An adjustable trailer for receiving a container, comprising a main member adapted to be attached at a free end thereof to a vehicle, at least one adjustable unit extending transversally of and being connected to the longitudinal main member. A length of the adjustable unit is adapted to be varied. An attachment mechanism is provided for locking the adjustable unit in a selected position. The trailer defines an area for receiving the container, with the width of this area being adapted to be adjusted via the adjustable unit so as to accommodate the container. The container is adapted to be mounted to the trailer. | 06-25-2009 |
| 20100133784 | VERSATILE, COLLAPSIBLE CART-TRAILER WITH MODULAR COMPONENTS - A collapsible cart-trailer includes a folding mechanism that folds the cart-trailer into a small form factor, at least two wheels, modular, and removable and compartmentalized storage. The collapsible cart-trailer is operable in a cart mode and a trailer mode. In the trailer mode, the cart-trailer may be coupled to a movable object by a collapsible, length adjustable tow bar. In the cart mode, the cart-trailer includes a collapsible handle. | 06-03-2010 |
| 20100219611 | SAFETY TRAILER - The present invention is directed to differing embodiments of safety trailers, which have first and second platforms and a safety wall positioned therebetween. The platforms and safety wall define an area protected from vehicular incursions. | 09-02-2010 |
| 20110221166 | Hitch Apparatus for Vehicles - A hitch apparatus includes a housing and a tow bar movably disposed within the housing. The housing includes spaced-apart first and second sections. At least one of the sections includes an elongated slot. The tow bar includes a guide member that extends outwardly from the tow bar at the proximal end thereof and that is operably engaged with the slot. The housing may include a pair of tow bar guide doors pivotally secured between the first and second sections that limit the extent which the tow bar pivots and that guide the tow bar as it is retracted. The housing may include a pair of guide posts extending between the first and second sections and the tow bar may include a pair of guide wings that contact the guide posts to limit the extent to which the tow bar can pivot and guide the tow bar as it is retracted. | 09-15-2011 |
| 20110248474 | TOW BAR SUSPENSION SYSTEM - A tow bar suspension system includes a tow bar pivotally connected to a trailer frame, first and second mounts coupling the suspension bar to the tow bar, an elongate connector, and a coupling link. The connector couples the coupling link and the suspension bar, while the coupling link couples the connection bracket and the trailer frame. The suspension bar is angled with respect to a longitudinal axis of the tow bar such that the weight of the tow bar is applied as a torsion force on the suspension bar, which resists this force to suspend the tow bar off a ground surface. The coupling link is adjustable in length to modify the pitch of the tow bar with respect to the ground surface. | 10-13-2011 |
| 20120139209 | TUGGER ATTACHMENT - Provided is a tugger attachment apparatus configured for use with a pallet transport. The pallet transport has a front drive portion and a rear load portion having a pair of forks. The tugger attachment includes a body, a fork coupling member at a bottom side of the body that is configured to secure the body to the forks, and a hitch supported by the body. A linkage can be provided that opens and closes the hitch in response to raising and lowering of the forks of the pallet transport. | 06-07-2012 |
| 20140265247 | Adjustable Aircraft Towbar - An improved aircraft towing apparatus, which is attachable to a small vehicle such as a golf or utility vehicle. The apparatus has a swiveling hitch bar pivotally mounted to a vehicle and a tow bar sleeve pivotally mounted to the center of the hitch bar, with the tow bar sleeve positioned underneath of the hitch bar. The device further comprises an extendable tow bar which is positioned within the tow bar sleeve. The tow bar is slidably insertable into the tow bar sleeve. The tow bar, when not in use, may be slid back through the tow bar sleeve such that the majority of the length of the tow bar is secured out of the way underneath the chassis of the utility vehicle. | 09-18-2014 |
| 20140312594 | Extendable Trailer Mount - The inventive technology relates to methods and apparatus for an improved self-contained extendable trailer mount that may be independently used, and/or retrofitted to existing vehicle mount/hitch systems. | 10-23-2014 |
| 20150035254 | HYDRAULIC EQUALIZING SPREADER BAR WITH DUAL SPREAD LINKS - A spreader bar includes a frame having a leading end and a trailing end. A pivot member is pivotally mounted to the trailing end of the frame and adapted to be removably connected to a spreader bogie. Spread links adapted to be removably connected to a trailer are pivotally and removably attached to the leading end of the frame. The length of the spreader bar may be changed by substituting spread links having different lengths. | 02-05-2015 |
