Description
- The present invention relates to a sink stopper, more particularly to a sink stopper adapted to be mounted fixedly in a drain hole of a sink.
- Conventional sink stoppers are shaped as plugs or discs. When water is to be retained in a sink, a sink stopper is used to seal a drain hole of the sink. On the other hand, when water is to be drained from the sink, the sink stopper is removed from the drain hole. However, in practice, when the sink stopper is removed from the drain hole, it is simply placed on one side of the sink, which can result in accidental dropping and misplacing of the sink stopper due to the lack of a connection with the sink.
- Therefore, the object of the present invention is to provide a sink stopper that can overcome the aforesaid drawback associated with prior art.
- Accordingly, the sink stopper of the present invention is adapted for use with a sink body having a base formed with a drain hole that is confined by a tubular hole-confining wall. The sink stopper comprises a strainer, an operating device, and a closure member.
- The strainer is adapted to be mounted on the base, and has a perforated strainer wall to be disposed in the drain hole.
- The operating device includes stationary and movable members, and a switching unit. The stationary member extends along an axis and is formed with a first mounting end that is mounted on the perforated strainer wall of the strainer. The movable member is coupled movably to the stationary member, and is formed with a second mounting end. The movable member is movable along the axis relative to the stationary member to move the second mounting end toward and away from the first mounting end. The switching unit is provided on the stationary and movable members, and is operable to retain releasably the movable member at a selected one of first and second positions relative to the stationary member. The second mounting end forms a first distance with the first mounting end when the movable member is at the first position. The secondmounting end forms a second distance with the first mounting end, the second distance being shorter than the first distance, when the movable member is at the second position.
- The closure member is mounted on the second mounting end of the movable member, is configured to form a clearance with the base to permit draining of water in the sink body through the drain hole when the movable member is at the first position, and is adapted to abut sealingly against the base to seal the drain hole when the movable member is at the second position.
- Other features and advantages of the present invention will become apparent in the following detailed description of the preferred embodiment with reference to the accompanying drawings, of which:
- Figure 1 is a schematic partly sectional view illustrating the preferred embodiment of a sink stopper according to the present invention when mounted on a sink;
- Figure 2 is an exploded perspective view of the preferred embodiment;

Themovable member 42 further has astop flange 426 that extends from one end of themovable member 42 opposite to thesecond mounting end 427. Thestop flange 426 is disposed in thereceiving space 411, and abuts against thetumbler mounting flange 410 to prevent removal of themovable member 42 from thestationary member 41. - In this embodiment, the switching unit includes a pair of looped
guide grooves 421 formed in opposite sides of themovable member 42, a pair of spring-loadedtumblers 44 mounted respectively in thetumbler holes 412 and projecting through the inner hole ends of thetumbler holes 412 to engage respectively theguide grooves 421, and abiasing member 43 disposed in thereceiving space 411 and biasing thestop flange 426 toward thetumbler mounting flange 410. Thetumblers 44 are movable along the lengths of thetumbler holes 412. Accordingly, themovable member 42 is biased by the biasingmember 43 along the axis to extend outwardly of thestationary member 41. As shown in Figures 4 and 5, eachguide groove 421 has first andsecond control points tumblers 44 engage therespective guide groove 421 at one of the first andsecond control points movable member 42 at a corresponding one of first and second positions relative to thestationary member 41. As shown in Figure 4, thesecond mounting end 427 of themovable member 42 forms a first distance with thefirst mounting end 413 of thestationary member 41 when themovable member 42 is at the first position. As shown in Figure 5, thesecond mounting end 427 forms a second distance with thefirst mounting end 413, the second distance being shorter than the first distance, when themovable member 42 is at the second position. - In this embodiment, as the axis extends in a vertical direction, the
first control point 4210 is disposedbelow thesecond control point 4211. Eachguide groove 421 further has afirst section 422 ascending from thefirst control point 4210 and having an upper end disposed at a level above thesecond control point 4211, asecond section 423 descending from the upper end of thefirst section 422 and extending to thesecond control point 4211, athird section 424 ascending from thesecond control point 4211 and having an upper end disposed at a level above thesecond control point 4211, and afourth section 425 descending from the upper end of thethird section 424 and extending to thefirst control point 4210. - Referring to Figures 2 and 4, the
closure member 5 includes apress cap 51 mounted on thesecond mounting end 427 of themovable member 42, and aseal ring 52 having an innerperipheral portion 520 that is connected to thepress cap 51 and askirt portion 521 that extends in radial outward directions from the innerperipheral portion 520. Theskirt portion 521 is configured to form aclearance 6 with thebase 11 to permit draining of water in thesink body 1 through thedrain hole 12 when themovable member 42 is at the first position (see Figures 3 and 4) , and is adapted to abut sealingly against thebase 11 to seal thedrain hole 12 when themovable member 42 is at the second position (see Figure 5) . In this embodiment, thepress cap 51 has a bottom side formed with amounting sleeve 512 for engaging thesecond mounting end 427 of themovable member 42, and acoupling sleeve 511 surrounding themountingsleeve 512 andhaving a distal end. Theclosure member 5 further includes afixing ring 53 fitted into thecoupling sleeve 511 and having a distal end formed with a radialoutward end flange 531. The innerperipheral portion 520 of theseal ring 52 is clamped between the distal end of thecoupling sleeve 511 and theend flange 531 on thefixing ring 53. - Inpractice, referring to Figure 4, while the
tumblers 44 engage therespective guide groove 421 at thefirst control point 4210, application of a first pressing force on theclosure member 5 against biasing action of thebiasing member 43 retracts themovable member 42 into thestationary member 41 and causes thetumblers 44 to move along thefirst sections 422 of theguide grooves 421 until thetumblers 44 are disposed at the upper end of thefirst sections 422. Subsequent removal of the first pressing force enables themovable member 42 to extend out of thestationary member 41 by virtue of the biasing action of thebiasing member 43 and causes thetumblers 44 to move along thesecond sections 423 until thetumblers 44 engage therespective guide groove 421 at thesecond control point 4211, thereby retaining themovable member 42 at the second position, as best shown in Figure 5. - Referring to Figure 5, while the
tumblers 44 engage therespective guide groove 421 at thesecond control point 4211, application of a second pressing force on theclosure member 5 against the biasing action of the biasingmember 43 retracts themovable member 42 into thestationary member 41 and causes thetumblers 44 to move along thethird sections 424 until thetumblers 44 are disposed at the upper end of thethird sections 424. Subsequent removal of the second pressing force enables themovable member 42 to extend out of thestationary member 41 by virtue of the biasing action of thebiasing member 43 and causes thetumblers 44 to move along thefourth sections 425 until thetumblers 44 engage therespective guide groove 421 at thefirst control point 4210, thereby retaining themovable member 42 at the first position, as best shown in Figure 4. - In sum, by simple pressing actions on the
closure member 5 to drive theoperating device 4, the sink stopper of this invention can seal or open thedrain hole 12 for water-retaining or water-draining without the need to remove the sink stopper from thedrain hole 12.
