    摘要: A ball-returning tennis net assembly comprises a net structure of an inner net and an outer net on each side of the inner net for gathering balls hit into the net structure in a manner preventing the balls from rebounding onto a playing surface of a tennis court and for causing the balls to drop into an elongate inclined tray positioned along the base of the net so that the collected balls will roll down the tray to one end of the net structure. The tray delivers the ball to an automatic ball return mechanism at the side of the court which has a powered paddle device for batting the balls to a selected location at either end of the court.

    摘要: A self-contained modular home a first section, a second section and a top section, each section having an interior which is 100% complete and an exterior which requires only siding or other exterior finish for completion. The three sections of the self-contained modular home are designed to be transported on a low boy trailer or other transport system to a permanent foundation site. The modular home incorporates a unique steel cable lifting system within the floor system which enables the modules to be set on the foundation with or without the use of a crane. The modular home is bolted to a permanent slab foundation by a steel strap securing arrangement in such a manner that a one and half inch air space is created under the home. The manner in which the self-contained modular home is constructed and secured to the permanent foundation provides the modular home with up to 160 mph wind protection, which is far greater than the typical 80 mph to 100 mph offered by most site or stick built homes currently on the market. Once the modular home arrives at the construction site, the home can be set and bolted to the concrete slab, made weather tight, connected to the local plumbing and electrical services and an be operational in about three hours.

    摘要: A basketball return device comprises a portable unit for positioning on a basketball court in a location generally underneath a basket into which shooting practice is to be conducted. The device includes a base with a ball-return mechanism therein and a vertically extending chute projecting upwardly from the base and terminating in a hoop-like top opening for positioning substantially directly beneath the basket. The ball-return mechanism includes a horizontal ball-collection and dispersion tube mounted in the base for swinging movement about a vertical axis so that the tube may be positioned to direct balls through an open end thereof to a required location on the court. The ball-return mechanism includes a solenoid operated plunger carried at the back of the tube for projecting balls therethrough and the device may include various electrical controls for automatically and semi-automatically operating the ball-return mechanism.
