Abstract: A rollable load bearing mat for protecting turf areas from damage caused by weight bearing loads, such as vehicle or pedestrian traffic, configured from a plurality of interconnected mat units having a plurality of spaced apart cell rows comprising a plurality of generally upstanding tubular cell members. The cell members comprise a series of first cell members and adjoining second cell members that, in the preferred embodiment, share a common sidewall and are axially offset. The cell rows are interconnected by a plurality of flexible strap members configured to allow the mat unit to be rolled for ease of handling and installation. The cell member sidewalls and the flexible strap members are configured to provide a substantially open cell member to facilitate plant growth through the mat unit. Connecting mechanisms at the periphery of the mat unit connect with adjacent mat units to form a unitary load bearing mat.

Abstract: A drip irrigation water distribution device having a housing with a top, bottom and side wall forming a chamber therein. The bottom of the housing has a rotatable coupling attached thereto and configured for attachment to a water conduit member, such as a riser, to allow water under pressure to enter the bubbler. A plurality of valves are disposed in valve openings in the housing. Each valve is in corresponding relationship with a valve receiving member that has an opening in communication with the chamber and a discharge passage. An outlet member connects to a distribution line. The opening is configured to receive a reduced section of the valve to selectively allow water to flow to the discharge passage. The opening is securely closed by lowering the reduced section until it tightly abuts against the opening. An integral screen is included to filter debris in the water supply.
