  • Patent number: 4558896
    Abstract: A handle for carrying loads has a grip and a strap extending from the grip. The grip is formed so that it is comfortable to hold. The free end of the strap has a bar which can be engaged in a slot so as to form the strap into a closed loop. In use, the strap is passed through a convenient part of the load before the bar at the end of the strap and the slot are engaged. When the grip is lifted to lift the load, the weight of the load and the configuration of the slot will keep the end of the strap engaged so that the load can be carried securely and comfortably.
