Abstract
A sink trap assembly includes an upper vertical tubular part having a side wall with a tubular outlet securable to a horizontal outlet pipe. The upper part also has an open upper end and a lower open end to enable the tubular part to be installed by upward movement to position the upper end in sealing engagement with a lower surface of a sink around a strainer with the outlet of the tubular part being directed in any desired horizontal direction. The sink trap assembly also includes a lower part sealingly engageable with a lower end of a tubular part to close the lower open end thereof. At least one of the parts is secured to the strainer to retain the trap assembly in position.
Claims1
A sink trap assembly comprising a strainer having a tubular inner portion with an outwardly directed flange at an upper end and an external screw thread on a lower end, said strainer also having a tubular outer portion with an outwardly directed flange at an upper end and an internal screw thread at a lower end, the tubular inner portion of the strainer being fittable in a sink opening with the outwardly directed flange of the tubular inner portion engaging an upper surface of the sink and with the lower end of the tubular inner portion projecting downwardly through the sink opening, and the tubular outer portion being screwable onto the lower end of the tubular inner portion beneath the sink,
- said sink trap assembly also comprising an upper vertical tubular part having a side wall with a tubular outlet securable to a horizontal outlet pipe, an open upper end, and a lower open end to enable the upper tubular part to be installed by upward movement to position the upper end in sealing engagement with a lower surface of a sink around the inner strainer portion with the outlet of the tubular part being directed in any desired horizontal direction, the upper end of the upper tubular part having an inwardly directed flange positionable between the lower surface of the sink and the outwardly directed flange on the outer portion of the strainer, when the outer strainer portion is screwed onto the inner strainer portion beneath the sink, to retain the tubular part in sealing engagement with the lower surface of the sink, the lower open end of the tubular part being larger than the outwardly directed flange of the outer strainer portion to enable the outer strainer portion to be engaged with the inner strainer portion by upward movement through the lower open end of the tubular part,
- and a lower part sealingly engageable with the lower open end of the upper tubular part to close said lower open end, the lower part and the lower end of the tubular part having cooperating screw thread means to enable the lower part to be detachably secured to the lower end of the tubular part.
