Abstract: Truck bed liners for pick-up trucks having the characteristics of railer type liners but not extending over the rail of the bed are disclosed. The liners consist of one piece plastic members having a bottom panel formed to receive the wheel wells in the truck bed, a front panel formed to lie substantially against the front wall of the truck bed, and substantially parallel side walls. The region adjacent the top of the side walls extends outward at an elevation just below the side rails of the truck bed, preferably extending to the local side wall of the truck bed for lateral support therefrom. The resulting truck bed liner defines a substantially rectangular cargo carrying platform interrupted of course as required by the wheel wells, without the liner extending over the rails of the truck bed.

Abstract: A restraining bar for use on pickup trucks and the like for clamping between the two sidewalls of the truck bed to restrain articles which otherwise would tend to drift around and/or fall over if not adequately retained. The restraining bar is comprised of first and second telescoping members, each having a friction pad at the distal end thereof for being forced against and frictionally retained by respective sidewalls of a pickup truck bed. Connected to the inner end of the smaller member of the telescoping pair is a spring member operable by an operating lever which, when in an upper or spring uncompressed position, is free to slide within the larger of the two telescoping members, though when pushed downward toward a spring compressed position will first engage and lock against interior opposing walls of the larger of the two telescopic members, and thereafter compress the spring, ultimately reaching an over center position to be self retaining.

Abstract: Pocket sized telephone line data communication devices which include acoustic coupling capabilities are disclosed. The couplers have a primary body member housing a microphone (or speaker) adjacent one face surface thereof for disposition flat against the ear piece (or microphone) of a conventional telephone handset. A flexible slide structure having a speaker (or microphone) therein is coupled to the body member and is slideable with respect thereto to extend outward to cover the microphone (or earpiece) of the handset, the flexibility of the flexible member together with the slide allowing varying amounts of extension and angularity between the flexible member and the body to accommodate handsets of different spans between and angularity of the earpiece and mouthpiece thereof. With the flexible member at its extreme retracted position, the entire assembly is quite small, readily fitting within a man's shirt pocket. Various embodiments are disclosed.
