Patent number: 7322583Abstract: The present invention is directed to a wheeled luggage item with an ergonomic telescopic handle assembly. The ergonomic telescoping handle assembly of the present invention allows a user to use the luggage using just one hand. Furthermore, the ergonomic telescoping handle assembly shifts the weight of the bag onto the bag, rather than the user's arm, reducing strain on the user's arm, and it provides for a greater space between the user's heel and the bag, reducing the chance that the user will kick the bag while walking. Finally, the ergonomic telescoping handle assembly of the present invention is stored compactly within the luggage, maximizing the volume available within the luggage for storage of personal items.Type: GrantFiled: January 14, 2005Date of Patent: January 29, 2008Assignee: JanSport Apparel Corp.Inventors: Daniel Kim, Doug Golenz

Patent number: 6575690Abstract: This invention relates to a two-wheeled cart with an extended handle for the levered lifting and balanced moving of bales, such as bales of hay. More particularly, hay baled in the form of a rectangular solid is received by the cart at a hay-bale-receiving loader frame and lifted from the ground under leverage about the wheels applied from the handle used for pulling the cart. Once the bale is lifted by the handle and centrally balanced on an axle between the wheels of the cart, the hay-bale-receiving loader frame on the cart can be pivoted in a plane parallel to the axle of the cart. This pivot can occur from a lifting disposition where the major axis of a bale receiving frame is parallel to the axle between the wheels, to a transport disposition where the major axis of the hay-bale-receiving loader frame is normal to the axle between the wheels.Type: GrantFiled: December 21, 2001Date of Patent: June 10, 2003Inventor: Robert Ansotegui
