POP UP STOPPER
ABSTRACT OF THE DISCLOSURE
A manually operable pop up stopper for a sink or the like comprises a head for sealing the sink and a tail for entry into the sink drain tube. Shoulders are provided on the tail which are positioned to engage in overflow wall openings of the drain tube, thereby limiting the upward axial movement of the stopper. Portions of the tail are configured to be biased into contact with the interior wall of the drain tube to retain the stopper in an axially set position.

SUMMARY OF THE INVENTION
In accordance with one aspect of the invention '' "' `
, 3L~L3q~r~
~ 3 - 393 P/7 C~
a stopper for use with a drain tube for a sink or the like c~nprises an axially elonged ~ nber having a head for generally closing the inlet to the drain tube of the sink and a tail dcwnwardly dependent fram the head for ilsertian into the drain tube. me tail includes sprungable portions for engaging wall portions of the drain tube so as to retain the stopper in an elevated position within the dram tuLbe, and stop means disposed to be engageable with a dc~nward facing edge of the drain tube so as to linnit the axial extent to which the stopper may be withdrawn frc~ the drain tube. Such edge may be, for example, an edge of an overflaw c~Llng norsnalIy provided in the wall of the drain tube. Preferably the stop means is moveable between radially spaced positions; it is still further preferred that the stop means is resiliently moveable, whereby it may be sprung into an edge engaging position when the tail is initially inserted into the drain tube.
In a preferred form of the invention, the stop means and the springable tail portions are integral portions of the tail, the tail as a whole being constructed of resilient material.
In such form of the invention~ the tail may oomprise a plurality of fingers, the stop means ccmprising a F~ir of opposed fingers, otsher generally opposed fingers formlng the springable tail portions for frictionally contacting interior wall portions of the drain tube. Desirably these other fingers will be configured so as to provide a wall contact over a limited axial length thereof.
Further, it is preferred that the fingers carrying the shoulders are configured so as to provide frictional contact with the interior wall portions of the drain tube.

In a still ~ r aspect of the invention a sealing ring circ~bscribes the head portion adj æent the junctl~e thereof with the fingers, and the head portion includes an enlaLged rim spao above the sealing ring for gripplng.

Referring now to the Fiyures in detail, the pop up stopper of the invention is identified generally therein 25 by the numeral 10. Stopper 10 cQmprises a head 12, and a tail 14 ~ormed by diametrir~lly opposed pairs of fingers 16, 18 which are dcw~wardly dependent from head 12. StDpper 10 ' ,~; `

is normally used in conjunction with an axially elorlgated drain tube 20 shown in Figures 4 and 5, which is generally constructed of non-corrodible material such as brass or plastic, an~ which has a smoot~. mternal wall of circular cross-section.
Drain tube 20 has an inlet opening 22 at orle en thereof surrounded by a flange 23, and an outlet opening 24 at the other end. A pair of diametrically opposed wall opeN ngs 26 having an edge 27 facing downwardly i.e. away from the outlet oEening, are provided intermediate the il~et and outlet openings for the ingress of drain water from an overflcw opening normally provided in a sink 28 and cormected ~hereto by passageway 29.
Drain tube 20 is of generally circular transverse cross-section. Such cross-section may be constant c~er the axial leng~h of the drain tube, or, particularly in the preferred case where the drain tube is of molded plastic structure, there will ke a small draft angle of about 0.5 such that the diameter of the drain tube decreases marginally frGm inlet opening 22 towards the outlet opening.
Stopper 10 is provided with a sealing surface form0d 20 by an 0 ring 30 which seats in groove 32 formed in the outer facing surface at the proximal end of fingers 16, 18. Fingers 16 are provided with a stop means comprising outwardly formed shoulders 34 located intermediate the ends thereof having peripheral portions which are diametrically spaced apart by a din~sion som~what greater than that of the drain tuke adjaoent wall openings 26. Shoulders 34 are axially disposed on fingers 16 s~ch that when tail portion 14 is inserted into drain tube 20, the shoulders will snap behind the upper edge 27 .. . ~ , ~ , 3L~3~51~
- 6 ~ 393 P/7 C~
of respective wall openings 26, as shcwn in E'igure 4, at which point the clearance between O ring 30 and the inlet 22 of the drain tube will be sufficient to Fx~nit a desired flow of water into the drain tube. It will be appreciated that such clearance will normally be less than the axial dime~sion of wall opening 26, otherwise the lcwer portions of shoulder 34 would interfere to s~me exten-t with the bottcm edge of an associated wall opening 26 as stopper 10 is pushed down, thereby preventing O ring 30 sealing against flange 23.
10 . When shoulders 34 are engaged in openings 26 it will not be Fossible to withdraw -the stopper fr~n its position in the drain tube by application of an upward force of normal magn.itude applied to the stopper. In order to permit the withdrawal withcut necessitating the use of tools, shoulders 34 are, in radial cross-15 section as best seen in Fig, 2, arcuately.form~d so as to blendsm~othly with the cutward facing surface of fingers 16 adjacent the sides thereof, in effect forming a cam surface 36. When stopper la is rotated about it longitudinal axis, the shoulders will be deflected inwardly as cam surface 36 engages axial 20 portions of the wall opening 26 whereby the shoulders 34 will disengage the wall opemng. Of course, where it is not desired that stopp~r 10 be readily withdrawn from the drain tube 20, the lateral ed~es of shoulders 34 will be made sharp so as to resist c~mmung action.
Fingers 16,18 in their rela~ed condition are formed such that the transverse outside diameter of tail 14 is generally less than the diameter of openlng 22 of drain tube 20. Portions ~, ~

of fingers 16,18 adjacent the distal ends thereof have a locally increased outside dia~eter, here formed by pads 38, such diameter being marginally greater than that of opening 22 and less than the diameter of shoulders 34. Pads 38 at least where formed on fingers 16 locate beneath shoulders 34, and will normally have an axial extent greater than th,~t of opening 26. The pads 38 generally blend smoothly with underlaying portions of fingers 16, 18 so as not to snag on axial openings 26. The tips of fingers 16,18 have an outside diameter less than that of opening 22 so as to facilitate the entrance of tail 14 into drain tube 20.
~hen fingers 16,18 are introduced into drain tube 20 the fingers are inwardly deformed and pads 38 urged into interfering contact with drain tube 20 so as to retain stopper 10 in any desired axially set position. It will be appreciated that the radial extent of at least fingers 16 adjacent openings 26 should be limited in ccmparison to the radial extent of the openings so as not to limit unduly the flow of water through overflow channel 29 into the drain tube 20.
Fingers 16, 18 being resiliently moveable are desirably formed from a therm~plastic material, with AES being particularly suited due to the relative ease with which it may be plated to simLlate metal~ W~ilst tail 14 may be separ~te~y for~ed and integrated with head 12 by any convenient means such as solvent bo~ding, it is preferred that stopper 10 be unipartitely molded (i~e. molded as a unitary part).
As previously stated, stopper 10 when inserted in drain tube 20 may be axially moved between raised and l~ered . .

positions by any convenient means. Preferably head 12 includes a handle means where~ the stopper may be gripped and for this purpose head 12 includes an enlarged rim 40 of greater diameter than that of the sealing ring 30 and which is spaced therefrom.
Opposed detents 42 having a locally increased thickness are formed on rin 40 to facilitate furth~er the finger gripping action.
The above described emtDdiment is for the purpose of illustrating the inventive concept, and is not mtended to k~
