| 20100084831 | Device for allowing a wheeled vehicle for individuals to be dragged in a folded configuration - A foldable wheeled vehicle for individuals includes a main body, front and rear wheels joined on the body, and an anti-tip wheel joined on a rear end of the main vehicle body; the rear wheels will be in an immobilized state when the vehicle isn't in-use; the anti-tilting wheel will move to be below the rear wheels automatically when the vehicle is folded; thus, the vehicle in the folded position can be dragged with the front wheels and the anti-tip wheel contacting the ground; secondly, the anti-tip wheel will be in a higher position than the rear wheels when the vehicle is in an expanded in-use position; thus, when the vehicle is moving along a slope and tilting rearwards, the anti-tip wheel will contact the ground to prevent the vehicle from tilting rearwards excessively to overturn. | 04-08-2010 |
| 20110006495 | STROLLER FRAME, PARTICULARLY FOR TRANSPORTING A CHILD - The invention relates to a so-called three-wheel stroller frame ( | 01-13-2011 |
| 20140183832 | COLLAPSIBLE PLATFORM TRUCK - A foldable platform truck includes a platform, two wheel-connecting bars rotatably attached to the platform, a handle assembly, a handle release and locking mechanism for controlling the handle assembly, a pair of first gear members and a pair of second gear members. The handle release and locking mechanism has an actuator to be operated to allow the handle assembly to pivot between an upright position and a horizontal position. When the handle assembly is in the horizontal position, the wheels are folded up underneath the platform and lie horizontally with respect thereto. And, when the handle assembly is pulled away from the platform to the upright position, the first gear members engage and turn the second gear members, resulting in the wheel-connecting bars rotating to fold out the wheels from underneath the platform toward an eventual perpendicular position with respect to the underside of the platform. | 07-03-2014 |

| 20100044983 | Collapsible Utility Cart - The present invention is directed toward a collapsible cart adapted for use in recreational areas. The cart includes a body, a support platform, and a first wheel assembly and a second wheel assembly. Each wheel assembly includes a frame and a wheel adapted to slide along the frame. The frame includes a pivot point that reorients wheels from a stowed position to a deployed position. The cart may further include removable fences, as well as a foldable backstop. In use, the cart may be folded from a deployed position, in which it rolls along a surface to transport items, to a stowed position, in which it is collapsed in a compact geometry for storage. The cart may further be integrated into a chair such that the platform provides a seat and a seat back. | 02-25-2010 |
| 20130062842 | COMPACT, CARRY-ON BICYCLES HAVING A SHARED DRIVE-AND-CHASSIS SPACE - The teachings provided herein are generally directed to compact vehicle drive mechanisms that can be used in the design of a foldable, carry-on vehicle. The compact drive mechanisms presented herein, for example, have contributed to the advent of the compact, carry-on bicycles set-forth in the teachings which include drive-and-steering units and drive-and-chassis units. | 03-14-2013 |
| 20150084296 | SPORTS BAG WITH INTEGRAL TRANSPORTATION SYSTEM - Disclosed is a sports bag assembly with an integral wheeled transportation system. The bag assembly can accommodate the transportation and storage of sports equipment. The wheels can be deployed and retracted with a single mechanical movement, and may be stowed within the geometry of the bag. The bag assembly can fit within the recessed areas of platforms on the rear of motorized golf carts; within conventional storage stands, racks, lockers, vehicle trunks and/or hatches typically found around golf courses and in residences; and within travel containers or other systems for traditional golf bags. The golf bag assembly may also include a ventilated club storage compartment to facilitate the drying of clubs (including grips), and allow drainage of fluids which may enter the interior of the bag assembly. The bag assembly can also include a support and suspension system which restrains the grip and upper shaft or hosel ends of clubs which stabilizes and protects clubs during transport and play. The restraint system also can enhance the golfing experience by reducing or eliminating noise generated by clubs banging together during transportation. The restraint system can also extend the life of golf clubs by preventing contact between clubs, which contact could damage and alter frequency settings for various clubs. | 03-26-2015 |
| 20160075358 | Auxiliary Grip of Collapsible Trolley - A collapsible trolley includes a frame, a carrier plate, two wheel units, a primary grip and two auxiliary grip units. The frame includes two lower tubes and two upper tubes each pivotally connected to a corresponding one of the lower tubes. The carrier plate is connected to the lower tubes. Each of the wheel units is connected to a corresponding one of the lower tubes. The primary grip is supported on the upper tubes. Each of the auxiliary grip units is pivotally connected to a corresponding one of the upper tubes. | 03-17-2016 |
