Definitions

  • This invention relates to bathtub drain valve controls. More particularly it relates to a drain control that is operated by an overflow cover that forms a smooth extension of the tub wall.
  • bathtubs have a drain opening at the bottom for draining out the water and a valve located in that drain opening for closing the drain.
  • Such bathtubs usually have an overflow opening which is in fluid communication with the drain.
  • the over­flow opening is located on a vertical wall of the tub and permits water to flow out to the drain in order to prevent the tub from overflowing in case someone forgets to turn off the water or in case a person enters the tub and raises the water level to too high a level.
  • a stationary overflow plate is mounted on the tub to conceal the overflow hole from view while leaving a bottom hole open.
  • the overflow plate is usually fixed on the bathtub wall and juts out from the normal surface of the wall.
  • a drain control lever is also common for a drain control lever to be movably mounted on the fixed overflow plate and to extend into the tub. The drain control lever is then connected through linkages to the drain valve at the bottom of the tub.
  • the object of the present invention is to provide a bathtub drain valve control device which is shaped and installed so as to complement the contours of the vertical bathtub wall to provide a smooth, substantially continuous surface against which a bather can comfortably lean and in which the overflow plate serves the additional function of a drain control lever.
  • the present invetion provides a bathtub drain valve control arrangement, comprising a sub­stantially vertical bathtub wall defining an overflow opening which is adapted to communicate with a down­wardly directed drainpipe, a bathtub floor defining a drain opening which is adapted to communicate with said drainpipe; a drain valve for opening and closing fluid communication through said drain opening; an overflow cover mounted on said substantially ver­tical bathtub wall so as to substantially conceal said overflow opening, characterized by said overflow cover being adapted to move between open and closed positions and having a generally smooth outer surface, such that, in said closed position, said overflow cover is substantially flush with said vertical bath­tub wall to follow the contours of the wall to provide a surface against which a bather could comfortably lean; and a linkage connecting said overflow cover and said drain valve so that moving said overflow cover to the open position opens said drain valve and moving said overflow cover to the closed position closes said drain valve.
  • the present invention also provides a drain control fitting suitable for mounting on a bathtub side wall through an overflow hole in the side wall, and suitable to be connected to a drain valve drive member positioned behind said side wall, said fitting being characterized by a cover suitable to cover at least a portion of said overflow hole; con­nection means for mounting said cover on said side wall in a pivoting fashion, such that the cover may swing towards and away from said side wall while mount­ed on it on a first pivot axis; a lever suitable to be connected to said drain valve drive member such that operation of said lever moves said drive member; a second pivot axis upon which said lever pivots; and linking means for linking the cover to said lever such that providing of said cover on said first axis pivots the lever on said second axis.
  • the bathtub drain valve control arrangement of the present invention is simpler than the overflow cover and drain valve control than previously avail­able.
  • the overflow cover and drain valve control combination is easy to operate and is relatively in­expensive. Further the arrangement provides a smooth surface against which a person can lean his back and thus two people may comfortably sit face to face, leaning against opposite walls of the tub.
  • the bathtub l0 has a bottom wall l2, a substantially vertical side wall l4, and two substantially vertical side walls l6.
  • the end wall l4 has a recessed portion (or pocket) 24 surrounding the overflow opening 20.
  • the recessed portion 24 is tapered as shown in the Figure 3 cross section, being narrow at the top and wider at the bottom.
  • An overflow plate 26 is mounted in the recessed portion 24 to conceal the overflow opening 20 from view.
  • the overflow plate or cover 26 is slightly recessed in the end wall l4 when in the Figure 3 position.
  • the recessed portion or pocket 24 extends slightly below the overflow plate 26 so that a person can reach his fingers underneath the free end of the overflow plate 26 to pull it outward and so that water can readily overflow through the overflow opening 20 (as indicated by the arrows in Figure 3).
  • the overflow plate 26 is preferably made in two pieces.
  • the outer piece 28 is preferably metallic and may have a finish which corresponds to the finish on the faucet and other fixtures used in conjunction with the bathtub l0. It has a generally smooth outer surface which, when the plate 26 is closed, is flush with the rest of the tub wall l4 and complements the contours of the vertical bathtub wall l4 to provide a smooth, substantially continuous surface against which a bather could comfortably lean.
  • the inner piece 30 is preferably a molded polymeric material (e.g. a plastic).
  • the inner piece 30 has an indentation 32 in its top edge (see Figure 6), and the outer piece 28 has a mating projection 34.
  • the bottom portion 36 of the outer piece is first wrapped around the lower edge of the inner piece 30, and then the projection 34 at the top of the outer piece 28 is snap-fit into place in the indenta­tion 32 of the inner piece 30.
  • the inner piece 30 includes an integrally molded arm 38 defining an aperture 39 which permits the overflow plate 26 to be connected to the linkages used to control the drain valve 40.
  • the inner piece 30 also includes a number of hinge eyes 42 near its top edge.
  • a stationary member 44 has mating hinge eyes 46 on its top edge.
  • a hinge pin 48 connects the over­flow plate 26 to the stationary piece 44 through the hinge eyes 42, 46, so that the overflow plate 26 can pivot relative to the tub l0 on this first, sub ­stantially horizontal axis.
  • the overflow plate 26 is movably mounted on the tub l0 at its top end and has a free lower end. It should be noted that the outer piece 28 projects slightly beyond the hinge eyes 42, 46 to conceal them.
  • the stationary piece 44 is fixed to the end wall l4 of the tub l0 by means of two screws 50 (only one shown in Figure 5) which clamp the stationary piece 44 and the drain extension 52 to the end wall l4 of the tub.
  • the screws 50 extend through apertures 54 in the stationary piece 44 and through the overflow opening 20 in the tub wall l4 and are received in the threaded apertures 56 of the drain extension 52.
  • a gasket 58 is pressed between the drain extension 52 and the outer surface of the end wall l4 to pro­vide a seal between the drain extension 52 and the end wall l4.
  • the linkages which permit the overflow plate 26 to serve as a drain valve control lever are as follows (see Figures 5 and 6);
  • a Y-shaped linkage 60 is pivotably connected at the point 39 to the arm 38 which is integral with the inner piece 30 of the over­flow plate 26.
  • the linkage 60 is pivotably connected to a rocker arm 62 at the point 6l.
  • the rocker arm 62 is pivotably mounted on the sta­tionary piece 44 at the point 64, so that the rocker arm 62 pivots about the fixed point (or second, substantially horizontal axis) 64.
  • a spring 66 is mounted over the inner portion of the rocker arm 62 between two washers 68, 70 which serve as stops.
  • the washer 70 bears against an integral extension 72 from the stationary piece 44 which ex­tends through the end wall l4 of the tub.
  • the exten­sion 72 has upper and lower camming surfaces 74, 76 which serve to define the two positions of the overflow plate (or valve control lever) 26.
  • the washer 70 bears against the upper camming surface 74.
  • the overflow plate 26 is pivoted counterclockwise (opened)
  • the washer 70 begins to move toward the lower camming surface 76.
  • the rocker arm is rotated counter­clockwise, the washer 70 moves until it is balancing on the point between the first and second camming surfaces 74, 76
  • the spring 66 causes the washer 70 to flip into contact with the lower cam­ming surface 76, snapping the overflow plate (the valve control lever) 26 into the open position, shown in Figure 4.
  • the spring 66 acts in a similar manner, causing the washer 70 to flip into contact with the upper camming surface 74 as it moves past the balanced position.
  • the rocker arm 62 is pivotably connected to the vertical linkage (or drive member ) 78, the length of which is adjustable by means of an adjustment arm 80.
  • the lower end of the adjustment arm 80 is connected to a spring 82.
  • the drain valve 40 is pivotably connected at the point 84 to a see-saw assembly 86 which rocks back and forth about the fulcrum point 88.
  • the assembly 86 can flex inward about the points 85, permitting it to be in­stalled through the drain hole l8, but it cannot flex outward, thereby permitting it to operate stiffly, in a see-saw motion when acted on by a downward force at either end.
  • the spring 66 causes the washer 70 to press against the upper camming surface 74, lifting the lower spring 82 off of the free end 90 of the seesaw linkage 86.
  • the weight acting on the right hand portion of the linkage 86 causes the right side of the linkage to fall downward, closing the drain valve 40.
  • the spring 68 causes the washer 70 to press against the second camming surface 76, lowering the spring 82 into contact with the free end 90 of the seesaw linkage 86, and the added force from the spring 82 causes the linkage 86 to rotate counterclockwise about the fulcrum 88, thereby opening the drain valve 40.
  • overflow plate 26 when the overflow plate 26 is in the closed position, it is flush with the inner surface of the vertical bathtub wall l4 to provide a smooth, sub­stantially continuous surface against which a bather can comfortably lean.
  • the recessed portion 24 of the end wall l4 permits the overflow plate 26 to be re­cessed in the tub wall to provide this smooth, flush surface.
  • the inner piece 30 is connected to the fixed member 44 by means of the hinge pin 48.
  • the drain pipe extensions l02 and 52 are connected to their respective openings l8, 20.
  • the extension l02 is threaded onto the flanged piece l04 which forms the drain hole l8.
  • the drain extension 52 is bolted to the fixed member 44 as was described earlier, with the installer extending his screw driver through the holes 5l in the inner piece 30 to reach the bolts 50.
  • the vertical linkage 78 is assembled with the ad­justment arm and the spring 82.
  • the leg l05 of the linkage 78 is inserted through the slot l06 of the adjustment arm 80 and into the upper hole l08 of the nut ll0, and the bolt ll2 then secures the nut ll0 at the desired position on the adjustment arm 80 by being threaded into the lower hole ll4.
  • the spring 66 and washers 68, 70 are placed on the rocker arm 62 and held in place by a cotter pin 69.
  • the vertical linkage 78 is hooked onto the end of the rocker arm 62, and the linkage 78, together with the adjustment arm 80 and spring 82 are moved under the indentation 7l in the fixed member 44, through the overflow opening 20, and are lowered down through the drain pipe extension 52.
  • a pin 65 is extended through the hole 64 in the rocker arm 62.
  • the pin 65 enters the horizontal recess 67 in the fixed member 44, and, when the washer 70 is brought into contact with one of the camming surfaces 74, 76, the pin 65 is pressed against the recess 67 in the fixed member 44, thereby mounting the rocker arm 62 on the fixed member 44.
  • the outer piece 28 is then installed over the inner piece 30 of the lever arm 26 as described earlier.
  • the see-saw assembly is connected to the drain valve 40 and is threaded into position with the free end 90 entering first through the drain hole l8.
  • the individual pieces of the see-saw assembly flex inward relative to each other in order to get around the bend l00 in the pipe l02.
  • the bather need only pivot the overflow plate up and down in order to con­trol the drain valve.
  • the drain valve is closed, the bather has a smooth, substantially con­tinuous surface against which to recline.
  • the plate may pivot on its side edge or about another axis (rather than at the top).
  • the particular nature of the lever or other operator used could be changed.
