Abstract: A carrying case has an elongated housing having a central and two end housing structures in overlapping, telescoping relationship so that the length of the carrying case can be adjusted. Hinges are connected to each housing with the hinge axes aligned so that the housings can be jointly rotated between open and closed positions without twisting the housing structures. Hinge alignment is possible by making the leaves of some hinges radially longer than the leaves of other hinges. Interengaging, load-bearing bosses are provided on the housing structures for adjustability to the length of the carrying case while providing strong connections, making it possible to use light weight material. Ribs and buttresses are molded as unitary parts of the central element and have an interengaging feature for reinforcement.

Abstract: A manually adjustable outboard motor mount comprises two bracket assemblies, one being attachable to a boat transom and the other being adapted to support an outboard motor. The motor bracket assembly is constrained to movement in a straight, substantially vertical path relative to the transom bracket assembly by the cooperation of interengaging ribs and recesses on the brackets. The brackets, which have their ribs on their outer faces and their recesses on their inner faces, can be formed from a single extrusion. Cross braces fit into the recesses on the inner faces of the brackets.

Abstract: A manually adjustable outboard motor mount comprises two brackets one attachable to a boat transom and one to which an outboard motor can be attached. The motor bracket is constrained to movement in a straight, substantially vertical path relative to the transom bracket by the cooperation of rods on one bracket with spaced bearings in sleeves on the other bracket. The motor bracket is adjusted vertically by a shaft threaded into the transom bracket and rotatable in a combined thrust and journal bearing in the motor bracket. A nut on the threads of the shaft can be tightened against a plate of the transom bracket to lock the motor bracket against vertical movement. The nut has three radial arms disposed at 120 degree angles relative to one another to allow convenient manual tightening.
