The present invention relates to control of a drain valve of a bath. In particular, it relates to drainage control actuated by an outlet cover forming a smooth extension of the bath wall.

Most bathtubs have drain holes at the bottom to drain the water out and valves are installed at the drain holes to close the drain holes. Such a bath usually has an overflow hole in fluid communication with the drain. The outlet hole is provided on the vertical wall of the bath and allows the drainage of water for drainage if the person forgets to shut off the faucet, the person enters the bath, or the water level is too high.

Typically, the fixed outlet plate is mounted on the bath so that the outlet hole is not visible with the bottom hole open. The outlet plate is usually fixed to the bath wall and protrudes from the vertical surface of the bath wall. It is also common for the drain control lever to be movably mounted on a fixed outlet plate and to extend into the bath. The drain control lever is connected to the drain valve at the bottom of the bathtub via a link connection.

One problem with the outlet plate of this prior art drain valve control is that it protrudes into the bath and stabs the person when he or she is leaning against the wall on which it is mounted. This restricts a person from using multiple bathtubs at once.

In order to solve this problem, attempts have been made to separate the outflow cover and the drain lever by inserting the trip lever into the recess or by using a separation cover to form a smooth comfortable surface. These devices required the user to operate the release lever to lift the cover or control the drainage.

The present invention relates to a substantially vertical tub wall defining an outlet hole intended to communicate with a drain pipe directed downward, a tub bottom defining a drain hole adapted to communicate with the drain pipe, and fluid communication through the drain hole. A drain valve control apparatus for a bath having a drain valve for opening and closing, and an outlet cover mounted to the tub wall to make the outlet hole almost invisible, the outlet cover being moved between the open and closed positions. It has a generally smooth outer surface, and when in the closed position it is almost coplanar with the wall along the contour of the bath wall to provide a surface on which the bather can rest comfortably, and the link opens the outlet cover. To the position, the drain valve opens; to the closed position, the drain valve So that the chain is to provide a drain valve control apparatus of the bath, characterized in that for connecting the outlet cover and the drain valve.

The present invention is directed to a drain contorl fitting adapted to be mounted to a side wall yarn of a bath through an outlet hole in the side wall and to be connected to a drain valve drive member located behind the side wall. A cover suitable for adequately covering at least a portion, connecting means for pivotally mounting the sidewalls such that the cover can pivot in a proximal and spaced direction relative to the sidewall with the cover mounted on the first pivot axis, the operation being drained A lever adapted to be connected to the drain valve drive member to move the valve drive member, a second pivot axis on which the lever is pivoted, and a cover such that the lever pivots on the second pivot axis when the cover is pivoted on the first pivot axis. To provide a drainage control fitting member characterized by link linking means for linking the lever to the lever.

Bath tub drain valve control device of the present invention is simpler than the conventional outlet cover and drain valve control device. The combination of outlet cover and drain valve control is easy to operate and relatively inexpensive. Moreover, the device is provided with a smooth surface on which the bather can lean back so that the two can sit comfortably face to face against the opposite wall of the bathtub.

Bath 10 has two sidewalls 16 that are substantially perpendicular to sidewall 14 that is substantially perpendicular to bottom wall 12. The bottom wall 12 (or bottom) of the bath 10 has ordinary holes 18 that serve as drainage holes. There is also a hole 20 in the vertical side wall 14 which serves as an outlet hole. Both the drain hole 18 and the outflow hole 20 are in fluid communication with the drain pipe 22. The side wall 14 has a recess 24 (or pocket) surrounding the outflow hole 20.

As shown in the cross-sectional view of FIG. 3, the recess 24 has a tapered shape in which the upper portion is narrow and widened at the bottom. The outlet plate or outlet cover 26 is mounted to the recess 24 to make the outlet hole 20 invisible. The outlet cover 26 is slightly recessed in the side wall 14 when in the FIG. 3 position. The pocket or recess 24 extends slightly below the outflow cover 26 so that a human finger can reach below the free end of the outflow cover 26 to pull it out, Water can easily flow out through the outlet hole 20 (as shown by the arrow in FIG. 3).

The outlet cover 26 is preferably made in two directions. The outer piece 28 is preferably metal and may have a finish fill that corresponds to the top finish fill with other fitting members used in connection with the bath 10. This fills the settling portion of the vertical sidewall 14 of the tub to provide a smooth and nearly continuous surface for the bather to rest on when the outlet cover 26 is closed, and the rest of the tub sidewall 4 It has a generally smooth outer surface that is coplanar.

The inner piece 30 is preferably cast from a polymeric material (ie, plastic). The inner piece 30 has a notch 32 at its upper edge (see FIG. 6) and the outer piece 28 has a mating engagement protrusion 34. In order to assemble the outer piece 28 to the inner piece 30, the bottom portion 36 of the outer piece first surrounds the lower edge of the inner piece 30 and then the protrusion 34 at the top of the outer piece 28. ) Is snapped into position with the notch 32 of the inner piece 30.

The inner piece 30 includes an integrally cast arm 38 defining an opening that allows the outlet cover 26 used to control the drain valve 40 to be connected to the link connection. The inner piece 30 also includes a hinge hole 42 near its upper edge.

The fixing member 44 has a mating hinge hole 46 thereon. The hinge pin 48 connects the outlet cover 26 to the fixing member 44 through the hinge holes 42 and 46, so that the outlet cover 26 is connected to the tub 10 on the first horizontal axis. Can be wheeled about. Therefore, the outlet cover 26 is rotatably mounted on the tub 10 at its upper end and has a lower free end. Note that the outer piece 28 protrudes slightly past them to conceal the hinge holes 42, 46.

The fixing member 44 is connected to the tub 10 by two screws 50 (see FIG. 5) that clamp the drainage extension 52 and the fixing member 44 to the end side wall 14 of the bathtub 10. It is fixed to the end side wall 14. The screw 50 extends through the hole of the fixing member 44 and the outlet hole 20 in the end side wall 14 and is received in the threaded hole 56 of the drainage extension 52. The gasket 58 is compressed between the drainage extension 52 and the outer surface of the end sidewall 14 to provide a seal between the drainage extension 52 and the end sidewall 14.

The link connecting means allowing the outlet cover to act as a drain valve control lever is pivotally connected at points 39 of the arm 38 integral with the inner piece 30 of the outlet cover 26. Y-shaped link 60 shown in the figure. At its other end, the Y-shaped link 60 is pivotally connected to the rocker arm 62 at point 61. The rocker arm 62 is pivotally mounted on the stationary member 44 at point 64 so that the rocker arm 62 pivots about the anchor point (or substantially horizontal second axis). The spring 66 is mounted over the interior of the rocker arm between two washers 68 and 70 acting as stop members.

The washer 70 bears against the integral extension 72 from the securing member 44 extending through the end sidewall 14 of the bath. The extension 72 has an upper and lower cam action surface 74 which acts to define two positions of the outlet cover 26 (or valve control lever).

As shown in FIGS. 3 and 6, the washer 70 is supported against the upper cam action surface 74 when the outlet cover 26 is in the closed position. The washer 70 begins to move towards the lower cam action surface 76 when the outlet cover 26 pivots counterclockwise (open). As the rocker arm rotates counterclockwise, the washer 70 moves until it is parallel at the point between the first and second cam action surfaces 74, 76 when the rocker arm moves a little away from the parallel position. The spring 66 flips the washer 70 into the lower cam action surface 76 and opens the outlet cover (valve control lever) in the open state shown in FIG. When closing the outer piece 28, the spring 66 acts in a similar manner in flip contact with the upper cam action surface 74 as the washer 70 passes through position.

At its innermost end, the rocker arm 62 is pivotally mounted to the vertical link connector (or drive member), so that its length is adjustable by the adjustment arm 80. The lower end of the adjustment arm 80 is connected to the spring 82. The drain valve 40 is pivotally connected at the point 84 to the seesaw link assembly 86 which swings back and forth with respect to the lever point 88. The seesaw link assembly 86 may be bent inward with respect to the point 85 and may be installed through the drainage hole 18, but may not bend outwardly, so that the seesaw link assembly 86 may act upon downward force at either end. Make it stiff in movement.

When the outlet cover 26 is in the closed position as in FIG. 3, the spring 66 is provided with the washer 70 pressing the upper cam action surface so that the lower spring 82 at the free end of the seesaw link assembly 86 is closed. Lift up. The weight acting on the right side of the seesaw link assembly 86 lowers the right side of the seesaw assembly downward and closes the drain valve 40. When the outlet cover 26 is lifted to the open position, the spring 66 compresses the washer 70 against the second cam action surface 76 and the force applied from the spring 82 causes the seesaw link assembly. The drain valve 40 is opened by rotating the 86 in the counterclockwise direction with respect to the lever point 88.

In particular, when the outlet cover 26 in FIGS. 1 and 2 is in the closed position, the vertical sidewalls 14 of the bath are connected with the inner wall to provide a smooth, almost continuous surface on which the bather can rest comfortably. Note that it is coplanar. The recess 24 in the end sidewall allows the tub wall of the outlet cover to be recessed to provide this smooth coplanar surface.

The inner piece 30 is connected to the fixing member 44 by a hinge pin 48 for installing the drain valve device on the bath 10. Drainage extensions 102, 52 are connected to respective holes 18, 20 of the bath. The drain extension body 102 is screwed to the flange piece 104 which forms the drain hole 18. The drainage extension 52 is bolted to the fixing member 44, as described above, and the installer can insert the screwdriver through the hole 51 in the inner piece 30 to reach the screw 50. have. The vertical link 78 is then assembled with the adjustment arm 80 and the spring 82. The leg 105 of the vertical link 78 is inserted into the upper hole 108 of the nut 110 through the slot 106 of the adjusting arm 80, and the bolt 112 then into the lower hole 114. The screw secures the nut 110 in the required position on the steering arm 80.

Springs 66 and washers 68, 70 are mounted on rocker arm 62 and fixed in place by cotter pins 69. The vertical link 78 is hooked on the end of the rocker arm 62 and, together with the adjustment arm 80 and the spring 82, directs the outflow hole 20 under the notch 71 in the fixing member 44. It is moved through and descends through the drainage extension body 52. Before the rocker arm 62 passes through the fixing member 44, the pin 65 extends through the hole 64 in the rocker arm 62. The pin 65 enters into the horizontal recess 67 in the fastening member 44 and is horizontal in the fastening member 44 when the washer 70 contacts the cam working surface of one of the cam working surfaces 74 and 76. Compressed against the recess 67, thereby mounting the rocker arm 62 on the fixing member 44. Then, the outer piece 28 is installed on the inner piece 30 of the outlet cover 26 as described above. The seesaw assembly is then connected to the drain valve 40 and screwed in place by the free end 90 to first enter the drain hole 18. The seesaw assembly bends inward with respect to each side to surround the band 100 in each side pipe 102.

When the outflow and drainage control assembly is installed as described above, the bather only needs to pivot the outflow cover up and down to control the drain valve. When the drain valve is closed, the bather can lean on a smooth, almost continuous surface.

It is apparent that modifications may be made to the preferred embodiments described above without departing from the scope of the present invention. For example, the cover may be pivoted on the side edge or on the other side (on top). In addition, the lever or other used operating means is replaceable.
