一种可拖行也可背负的带轮背包，便于携带物品。
专利摘要
一种可拖行的带轮背包，包括连接至弯曲的单杆伸缩拖行构件的拖行手柄，该拖行构件在不使用时缩回背包内。拖行构件的弯曲为附接至拖行构件的背板提供支撑，背板经成形使得背包可舒适地支撑在佩戴者背部。带有轮子的刚性底座枢转地附接至拖行构件的底端。枢转附接允许底座和轮子在背包被佩戴或沿地面滚动时独立于拖行构件移动。
Original abstractA towable, wheeled-backpack includes a towing handle attached to a curved, single-pole, telescoping towing member which retracts into the backpack when not in use. The curvature of the towing member provides support for a backing sheet that is attached to the towing member, and the backing sheet is contoured so that the backpack can be comfortably supported on a wearer's back. A rigid base with wheels is pivotally attached to a bottom end of the towing member. The pivot attachment allows the base and wheels to move independently of the towing member as the bag is worn or as the bag is rolled along the ground.
