Appl. No.:

13/237777

Inventors:

Donald P. Clark - Tucson AZ, US

International Classification:

B21D 53/88

US Classification:

298972, 29897312, 292815, 403 53, 403 83

Abstract:

A connector and method of connecting two surfaces in an irregular, interrupted, or non-uniform space is provided. The connector is composed of at least one link, wherein each link has an adjustable spatial feature such as the length, thickness, or angle of the link. The spatial features of the links are adjusted to custom fit the connector to the two surfaces and the available space therebetween. Once the links have been adjusted to provide a satisfactory custom fit, the adjustable spatial features of the links may be fixed to form a substantially permanent solid structure or may be recorded to allow production of a custom shaped connector with substantially the same spatial features as the custom fit connector.

US Classification:

239106, 239204, 222566

Abstract:

A pop-up irrigation device for use in a low pressure irrigation device is described. The device has a housing, a riser partially extensible from the housing and a nozzle body removably attached to an end of the riser in a non-threaded manner, such as using a snap-fit, or in a threaded manner. One, two or more connection tubes or ports may extend laterally from the housing and can each be configured to be connectable to flexible irrigation tubing. Ribs may extend from the housing to facilitate retention when buried. An annular cap can be attached to the open end of the housing and may include an annular, radially-inward extending seal. The closed end of the housing may include a depending stake with a plurality of blades to facilitate mounting of the housing relative to the ground.
