초록 ▼

A safety trench drain conduit formed of first and second trench drain elements each in the form of an open top channel having imperforate bottom and sidewall portions. The first trench drain element is located and retained within the second trench drain element and is constructed and arranged to allow liquid access thereto from outside the second trench drain element. The second trench drain element bottom and sidewall portions envelope those of the first trench drain element. The second, outer, trench drain element sidewall portions include transverse surfaces above and laterally outward of and sloped inwardly toward the first trench drain element to direct any seepage near the entrance of the trench drain toward the open top of the first trench drain element. Longitudinally extending lateral flanges extending from an adjacent and upper portion of the sidewalls of the first element overlie and are supported by transverse longitudinally extending surfaces of the second element in order to support the first element within the second and to provide a space between an outside bottom surface of the first element and an inside bottom surface of the second element. The space extends essentially the length of the trench drain and is suitable for collecting liquid that may leak or pass through the first element. The height of the first element sidewalls increases from a first end to a second end while the height of the second element sidewalls is constant thereby providing a longitudinal slope to the first trench drain element relative to the second. Longitudinal frame rails secured at the opening to the inner trench drain element support a perforate trench drain cover. The trench drain is installed in a floor or the like with the cover flush with the surrounding surface and the upper ends of the outer element sidewalls beneath and covered by the surrounding surface, where it is protected from wear and tear.

대표청구항 ▼

An elongate safety conduit for collecting liquids, comprising: a. first and second conduit elements each in the form of an open-topped channel-shaped member having a first end and a second end and substantially liquid impermeable bottom and sidewall portions; b. the first conduit element located and retained within the second and constructed and arranged to receive liquid through the open top; c. the second conduit element enveloping the first; d. support means for supporting the first conduit element within the second conduit element wherein at least a portion of the outside bottom surface of the first element is above the inside bottom surface of the second to provide a space therebetween, said space extending essentially the length of said conduit and suitable for collecting liquid that may leak through the first element; e. each element being formed of discrete sections having interengaging ends; f. the distance between the first conduit element inner bottom surface and the second conduit element inner bottom surface decreasing in a longitudinal direction extending from the first end to the second end; and g. means sealing interengaging ends of said sections against leakage.
