A lay-in wireway, comprising:
- a pair of wireway sections connected end to end to form a junction, the wireway sections each having a corresponding open side;
- a joint connector adapted to rest on the open sides of the wireway sections adjacent the junction between the two wireway sections when said joint connector is in a closed position;
- first gasket means, carried underneath said joint connector and positioned between said joint connector and each of said wireway sections, for resiliently sealing between said joint connector and said wireway sections;
- a pair of covers, each one of which is hingedly connected to a respective one of said wireway sections, said covers being movable between an open position wherein said open sides of said wireway sections are uncovered and a closed position wherein said covers overlie said joint connector and cover said open sides of said wireway sections;
- second gasket means, positioned between each of said covers and said joint connector where said covers overlie said joint connector, for resiliently sealing between said covers and said joint connector;
- latch means, operably associated with each of said covers, for latching said covers in their said closed positions and for compressing said first and second gasket means on opposite sides of said joint connector;
- and
- a floating pivot means for pivotally connecting said joint connector to at least one of said wireway sections so that said joint connector can pivot relative to said wireway sections between its said closed position and an open position, and for allowing said joint connector to float between said covers and said wireway sections as said covers are moved to their said closed positions so that a substantially uniform sealing pressure is provided between said first gasket means and said wireway sections;
- wherein said floating pivot means includes an elongated slot disposed in said joint connector, and a pivot pin attached to said pair of wireway sections, said elongated slot having a longer dimension oriented generally perpendicular to said open sides of said wireway sections, and said pin being received in said slot so that said pin defines a pivotal axis generally parallel to a length of said wireway sections and so that said joint connector is slidable along said longer dimension of said slot relative to said pin;
- wherein adjacent ends of said wireway sections at said junction each include an outwardly extending flange;
- and
- wherein said pivot pin is defined as a pivot pin portion of an elongated fastener extending between said flanges to connect said wireway sections, said pivot pin portion being an enlarged diameter portion of said fastener extending out from one of said flanges away from the other of said flanges.
