Abstract
Abstract A pack frame having side frame members and crossbars extending between the side frame, worn on the back by means of a pair of shoulder straps with the lower ends of the side frame members pin-connected to a hip belt for transferring part of the load carried by the frame to the wearer''s hips. In another aspect, the side frame members have wheels at their lower ends and connecting members at their upper ends for attachment to the hip belt for rolling the frame over the ground, the user pulling it forward as he walks via the attachment of the frame to the hip belt. The connecting members are movable between a retracted position extending toward one another from the opposite sides of the frame for utilization of the frame as a back pack frame, and a position extending forward for utilization of the frame as a rolling cart.

Claim 1
Independent Claim
359 words
A pack frame comprising a pair of generally parallel, spacedapart side frame members and cross members extending between the side members, a pair of shoulder straps for the pack frame and a hip belt comprising pad means engageable on the wearer''s hips, a strap secured to the outside of the pad means adapted to encircle the wearer, means at the ends of the strap for fastening the hip belt in place on the wearer, and means for connecting a respective side member adjacent its lower end to the hip belt at each side of the belt as it is worn for transferring a portion of the weight of the load carried by the frame to the wearer''s hips, said connecting means comprising at least one hole in the strap at each side of the hip belt, a hole in each side member adjacent its lower end, and a headed pin at each side of the hip belt extending through the respective hole in the strap and the hole in the respective side member for Connecting each side member adjacent its lower end to the hip belt, said strap being free in part of the pad means to permit the pin to be inserted through the hole in the strap from the side thereof toward the pad means and through the hole in the adjacent side member, with the head of the pin bearing against the outside of the pad means, said pad means including a relatively thin, stiff protector member between the head of each pin and the pad means, a body of resilient, flexible foam material of such length as to extend around the wearer''s back from one side to the other, and a cover enclosing the foam material, said protector member being bonded to the outside of the foam and being enclosed within the cover, and said strap being stitched to the outside of the cover, so that the pad means including said protector member, when worn by the wearer, is interposed as a cushion between said headed fastener member and the wearer and said protector member prevents gouging of the wearer by said headed fastener member.
