2. Description of the Prior Art Almost all bathtubs have a drain provided at the bottom of the bath for draining water and a valve provided at the drain for closing the drain. Such a bath usually has an overflow water outlet for discharging overflowing water, so that the overflow water outlet can be fluidly passed through the drain outlet, that is, without leaking water. Connected. This overflow water outlet is provided on the vertical wall of the bathtub if someone forgets to close the faucet, or
When the bather rises too much when entering the bathtub,
Water can be discharged from the overflow outlet to prevent hot water from overflowing the bathtub.

Usually, a fixed drainage plate is attached to the bathtub, and the drainage plate covers the overflow water discharge port so as not to be seen. On the other hand, the drain at the bottom of the bath is not covered. Also widely used is a method in which a drainage control lever is movably attached to the fixed drainage plate and the lever is extended into the bath. This drain control lever is connected to a drain valve at the bottom of the bath.

[0004]

One of the problems with the conventional drain valve controller and drain plate is that the drain valve controller and drain plate protrude into the bathtub and the drain valve controller And the drainage board sticks on the back of the person trying to lean against the wall of the bathtub. Therefore, the drain valve control device and drain plate are not used in many bathtubs, but are used only in bathtubs where only one person can enter at a time. In order to solve this problem, an attempt has been made to separate the drain plate and the drain lever (To do this, the moving lever is placed in a pocket to form a smooth surface against which a person leans. To use another covering member). In such a device, the bather must lift the drain plate and move the lever for drainage control.

It is an object of the present invention to define a vertical bath wall profile
It is an object of the present invention to provide a drainage control device for a bathtub having a shape and structure in which the drainage port plate acts as a drainage control lever by making a smooth continuous surface on which a bather can comfortably lean.

The top edge of the inner piece 30 (FIG. 6) is scored and the outer piece 28 has a protrusion 34 that fits the score. To assemble the outer piece 28 to the inner piece 30, first surround the lower edge of the inner piece 30 with the lower portion 36 of the outer piece, and then project on the top of the outer piece 28. Insert the portion 34 into the score of the inner piece 30.

The inner small piece 30 has an arm 38,
The arm 38 is integrally formed with the hole 39 by molding. The small piece 30 on the inner side can connect the drain port plate 26 to a connecting member that controls the drain valve 40. Further, a large number of small holes 42, 42 for hinge connection are provided at the top edge of the inner small piece 30.

A small hole for connecting a hinge is provided at the top edge of the fixing member 44. This small hole is used for the hinge connection. The hinge pin 48 and the small hole for hinge connection are used to connect the drainage plate 26 to the fixing member 44, and by this connection, the drainage plate 26 is centered on a substantially horizontal first axis. It can rotate with respect to the bathtub 10. Therefore, the drainage plate 26 can be movably attached to the bathtub 10 by using the top edge thereof. It should be noted that the outer small piece 28 has the small holes 42, 4 for connecting the hinges.
6 is a little more protruding. The purpose of projecting in this way is to hide the small holes 42, 46 for hinge connection.

The fixing member 44 is fixed to the end wall body 14 of the bathtub 10 by screws 50, 50, ... (Only one is shown in FIG. 5), which is used for fixing the fixing member 44 and the drainage. The extension 52 is clamped to the end wall 14 of the bath. The screws 50, 50 ... penetrate the hole 54 of the fixing member 44 and the overflow water discharge port 20 of the end wall body 14 of the bathtub and enter the screw hole 56 of the drain extension 52. . The gasket 58 is pressed between the drain extension 52 and the outer surface of the end wall 14 of the bath. The gasket 58 is for sealing between the drain extension 52 and the bathtub end wall 14.

The connecting member allows the drainage plate 26 to function as a drainage valve control lever as follows (FIGS. 5 and 6). That is, the Y-shaped first connecting member 60 is rotatably connected to the arm 38 at a point 39, and the arm 38 is connected to the drain plate 26.
To be integrated with the small piece 30 inside. The connecting member 60 is rotatably coupled to a rocker arm 62 at a point 61 at the other end. The rocker arm (second connecting member) 62 is attached to the fixing member 44 at a point 61.
The rocker arm 62 can be rotated about a fixed point (that is, a substantially horizontal second axis) 64 as a center. Spring 6
6 is attached inside the rocker arm 62 between the two washers 68, 70.
0 acts as a plug.

The washer 70 supports an extension 72 which extends integrally from the fixing member 44, which extends through the end wall 14 of the bath. Extension 7 above
2 has upper and lower surfaces 74 and 76 acting as cams, and these upper and lower surfaces 74 and 76 are the drain plate (that is,
It acts to form the two positions of the lever controlling the valve).

When the drainage plate 26 is in the closed position, the washer 70 supports an upper surface 74 which acts as the cam, as shown in FIGS. When the drainage plate 26 rotates counterclockwise, the washer 70
Starts moving toward the lower surface 76 acting as the cam. When the rocker arm rotates counterclockwise,
The washer 70 moves to balance at a point between the camming first and second surfaces. When the rocker arm 62 goes straight beyond the balance position, the spring 66 moves the washer 70 into contact with the lower cam surface 76, and as shown in FIG. To the open position. When the valve control lever 28 is closed, the spring 66 is operated in the same manner as described above to move the washer 70 into contact with the upper cam surface 74. This is the same as when the washer moves past the balance position.

The innermost end of the rocker arm 62 is
The vertical connecting member (that is, the driving member) 78 is contacted. The length of the connecting member 78 has an adjusting arm 80.
Regulated by The lower end of the adjusting arm 80 is connected to the spring 82. The drain valve 40 is rotatably connected to a seesaw device 86 at a point 84 which swings back and forth about a fulcrum 88. The seesaw device 86 can flex inwardly about the point 85, and this flexing allows it to be attached through the drainage port 18. However, since the seesaw-type device 86 cannot bend outward, the seesaw-type device can perform a strong operation by the seesaw movement when a lowering force is applied to the other end.

When the drain plate 26 is in the closed position as shown in FIG. 3, the spring 66 causes the washer 70 to move.
Is pressed against the upper cam surface 74, and the lower spring 82
Are lifted away from the unconstrained end 90 of the seesaw device 86. When a force is applied to the right side portion of the connecting member 86, the right side portion of the connecting member lowers to close the drain valve 40. When the drain plate 26 is raised to the open position, the spring 68 causes the washer 70 to move.
Is pressed against the second cam-acting surface 76, the spring 82 is lowered until it contacts the unconstrained end of the seesaw-type connecting member 86, and the force exerted by the spring 82 causes the connecting member 86 to move. Rotates counterclockwise about the fulcrum, which opens the drain valve 40.

Here, the point to be particularly noted in FIGS. 1 and 2 is that when the drain plate 26 is in the closed position,
This drain plate 26 is flat with the inner surface of the vertical bath wall 14 to form a smooth and nearly continuous surface, thus allowing the bather to comfortably lean. Since the end wall 14 has the recess 24, the drain plate 26 enters the recess to form the flat and smooth surface on the bath wall.

To incorporate the drain valve into the bath 10, a hinge pin 48 is used to connect the inner strip 30 to the fixed member 44. The extension portions 102 and 52 of the drain pipe are respectively connected to the corresponding opening portions 18 and 2
