A collapsible carrier including an inflatable roller assembly for transporting a load such as a downed game animal or an injured person in remote areas over rough terrain is disclosed. The collapsible carrier includes a generally rectangular load supporting frame fabricated from light-weight, tubular material. The load supporting frame includes forward and rear frame sections being interconnected by a pair of triangular support frame members extending therebetween and being adapted for sliding, telescoping engagement with the forward and rear frame sections permitting convenient assembly or disassembly of the carrier. The carrier includes a cylindrical, inflatable roller assembly having axial bearings which is fabricated from a flexible fabric material capable of containing compressed air and adapted to be transversely mounted between the support frame members. The bearings are configured and dimensioned for insertion within an elongated tube extending through the roller assembly being retained therein when the roller is in an inflated condition. In an alternative embodiment the roller is provided with an elongated solid axle which extends therethrough and is adapted for attachment to the support frame members imparting rotational movement to the roller. The carrier may be grasped using handles attached thereto by the user in a conventional manner or, in the alternative, may be secured about the waist of the user with an optional harness belt. The collapsible carrier may be conveniently disassembled into its component parts for storage within a conventional mountaineer's back pack until it is deployed.
