Abstract
A toilet tank fill assembly incorporating a standpipe which is adjustable along a plurality of discrete positions to adjust the height of the fill valve within the tank. The standpipe includes a fixed tube which is secured to the inlet port of the tank and an adjustable tube matingly attached to the fixed tube and carrying the fill valve at an upper end. The fixed tube has a plurality of peripheral camming grooves which represent the discrete positions of adjustment. The adjustable tube includes a slot receiving a locking clip designed to engage the grooves of the fixed tube to selectively prevent telescoping adjustment of the tubes. Rotation of the adjustable tube removes the clip from the groove allowing adjustment of the standpipe length.
Claims20
A fill valve assembly for selectively filling a fluid reservoir, said fill assembly comprising:
- an upright standpipe adapted to be mounted within the fluid reservoir for delivering fluid therethrough, said standpipe includes a fixed tube portion and an adjustable tube portion telescopically attached to said fixed tube portion;
- a fill valve mounted to said adjustable tube portion of said standpipe, said valve being movable between a closed portion preventing the flow of fluid and an open position so as to allow the flow of fluid therefrom;
- and
- means for adjusting a length of said standpipe along a plurality of discrete positions to vary the position of said fill valve within the reservoir, said means including a plurality of lateral grooves formed in an exterior surface of said fixed tube portion defining said discrete positions and a locking clip mounted to said adjustable tube portion selectively engageable with said lateral grooves to prevent telescoping movement of said adjustable tube portion relative to said fixed tube portion;
- said fixed tube portion including opposing flat surfaces extending longitudinally along said fixed tube portion whereby rotation of said adjustable tube portion in a first direction aligning said locking clip with said flat surfaces facilitates telescoping adjustment of said adjustable tube portion relative to said fixed tube portion and rotation of said adjustable tube portion in a second direction engaging said locking clip with one of said lateral grooves prevents telescoping adjustment.
A fill valve assembly for selectively filling a fluid reservoir, said fill valve assembly comprising:
- an upright standpipe adapted to be mounted within the fluid reservoir for delivering fluid therethrough;
- a fill valve mounted to an upper end of said standpipe for controlling the flow of fluid into the fluid reservoir;
- and
- means for adjusting the length of said standpipe along a plurality of discrete positions, said standpipe including a first fixed tube portion having a plurality of spaced apart lateral grooves defining said discrete positions of adjustment and a second adjustable tube portion matingly mounted to said first fixed tube portion, said second tube having locking means selectively engaging said grooves to fix said length of said standpipe and said first fixed tube portion including opposing flat surfaces extending longitudinally along said fixed tube portion whereby rotation of said adjustable tube portion in a first direction aligning said locking means with said flat surfaces facilitates telescoping adjustment of said adjustable tube portion relative to said fixed tube portion and rotation of said adjustable tube portion in a second direction engaging said locking means with one of said lateral grooves prevents telescoping adjustment.
A fill valve assembly for selectively filling a fluid reservoir, said fill valve assembly comprising:
- an adjustable standpipe adapted to be mounted within the fluid reservoir for delivering fluid therethrough, said standpipe including a fixed tube portion adapted to be mounted within the fluid reservoir and an adjustable tube portion telescopically mounted on said fixed tube portion;
- a fill valve mounted to an upper end of said adjustable tube portion for controlling the flow of fluid through said fill assembly;
- and
- means for adjusting the length of said standpipe by adjusting the position of said adjustable tube portion relative to said fixed tube portion along a plurality of discrete positions, said fixed tube portion including a plurality of spaced apart lateral grooves defining said discrete positions of adjustment, said adjustable tube portion including locking means selectively engaging said grooves to fix said length of said standpipe;
- said fixed tube portion includes opposing flat surfaces extending longitudinally along said fixed tube portion whereby rotation of said adjustable tube portion in a first direction aligning said locking means with said flat surfaces facilitates telescoping adjustment of said adjustable tube portion relative to said fixed tube portion and rotation of said adjustable tube portion in a second direction engaging said locking means with one of said lateral grooves prevents telescoping adjustment.
