Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a device for controlling a drain valve of a bathtub.
More specifically, the present invention relates to a drainage control fitting connected to a drainage valve driving member.

[Prior art and its problems]

Most bathtubs have a drain in the bottom of the bathtub to drain water and a valve in the drain to close the drain. Such bathtubs usually have an overflow outlet for draining overflow water, the overflow outlet being such that the overflow outlet can be passed fluidly, i.e. without leaking water, into said drain. Connected.
This overflow outlet is installed in the vertical wall of the bathtub, and is used in case someone forgets to turn off the faucet or the water level rises too high when a bather enters the bathtub.
To prevent hot water from overflowing from the bathtub, water can be drained from the overflow outlet.

Usually, a fixed drain plate is attached to the bathtub.
The drain plate invisibly covers the overflow outlet. In contrast, the drain at the bottom of the bathtub is not covered. It has also been widely adopted to movably attach a drain control lever to the fixed drain plate and extend the lever into the bathtub. This drain control lever is connected to a drain valve at the bottom of the bathtub.

One problem with such conventional drain valve control device and drain plate is that the drain valve control device and drain plate protrude into the bathtub, and the drain valve control device and drain plate are attached to the bathtub wall. It is a stab in the back of someone who tries to lean on it. For this reason, the drain valve control device and drain plate described above are not used in many bathtubs, and are only used in bathtubs that accommodate only one person at a time. To solve this problem, an attempt was made to separate the drain plate and the drain lever. (Use a separate sheathing member to In such devices, the bather must lift the covering member and move a lever for controlling drainage.

[Object of the Invention] The object of the present invention is to form a substantially vertical contour of the bathtub wall.
To provide a drain control fixture for a bathtub having a shape and structure in which the drain outlet plate acts as a drain control lever, supplementing the surface so that it becomes a smooth, almost continuous surface on which a bather can lean comfortably.

[Summary of the invention]

The present invention provides a drain control fitting suitable for being attached to a side wall of a bathtub so as to pass through an overflow port of the side wall, and connected to a drain valve driving member attached behind the side wall. The drain control fixture is configured to control the drain when a suitable covering member for at least partially covering the drain and the drain plate are attached to the bathtub side wall and attached to the first axis of rotation. a coupling device for rotating the spout plate toward the side wall of the bathtub, and a rocker arm connected to the drain valve drive member for moving the drive member; and a rocker arm for moving the drive member. and,
In order to rotate the rocker arm about the second axis by rotating the rocker arm about the second axis of rotation and the drain plate by rotating the rocker arm about the second axis, and a connecting member for connecting to a rocker arm.

〔effect〕

The construction of the bathtub drainage control fixture of the present invention is simpler than conventional drain plates and drainage control fixtures. This combination of drain plate and drainage control fixture is easy to use and relatively inexpensive. Furthermore, the device has a smooth surface on which a person can lean, and two people can comfortably face each other while sitting on opposite walls of the bathtub.

〔Example〕

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

In the figure, a bathtub 10 has a bottom wall 12, substantially vertical side walls 14, 14, and substantially vertical side walls 16, 16.
has. Typically, the bottom wall (i.e., bottom plate) 12 of the bathtub 10 is provided with a hole 18 that acts as a drain port. Further, the vertical end wall 14 is also provided with an opening 20 (discharge port) which acts as an overflow water discharge port. The drain port 18 and the overflow water outlet 20 are connected to a drain pipe 22 such that fluid can pass therethrough without leaking. Above end side wall 1
4 is provided with a recess (ie, pocket) 24 surrounding the overflow water outlet 20.

As shown in FIG. 3, the recess 24 has a tapered cross section with a narrow top and a widened bottom. As shown in the figure, the drain plate 26 is attached to the recess 24 so as to cover the overflow water outlet. The outlet plate or cover 26 defines a cavity within the end side wall 14 when in the position shown in FIG. This empty space, that is, the pocket 24 is connected to the drain port plate 26.
It is formed slightly below. This is done by inserting a finger under the free end of the drain plate 26 and pulling the drain plate outward.
This is to allow water to easily flow out from the overflow water outlet 20 (as shown by the arrow in FIG. 3).

Preferably, the drain plate 26 is composed of two pieces. The outer piece 28 is preferably made of metal and has a finish that corresponds to the finish of the stopper or other fixed fitting on the bathtub 10. The outer surface of the outer piece is substantially smooth, and the drain plate 26 is shaped to be flush with the rest of the bathtub side wall 14 when closed, and to complement the contour of the vertical bathtub side wall 14. This creates a smooth, almost continuous surface that allows bathers to wash comfortably.

The inner piece 30 is preferably made from a molded polymeric material (eg, a plastic material). The top edge of the inner piece 30 (the sixth
) is provided with a notch on the outer piece 28.
In order to assemble the outer piece 28, which has a protrusion 34 that fits into the notch, to the inner piece 30, the lower edge of the inner piece 30 is first surrounded by the lower part 36 of the outer piece; Next, place the protrusion 34 on the top of the outer piece 28 into the notch of the inner piece 30.

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

A small hole 46 for hinge connection is provided at the top edge of the fixing member 44 . This small hole 46 is used for the hinge connection. The drain plate 26 is coupled to the fixing member 44 using the hinge pin 48 and the hinge coupling small holes 42, 46, and this coupling causes the drain plate 26 to be aligned with the substantially horizontal first axis of rotation. It can rotate relative to the bathtub 10 about the hinge pin 48 . Thus, the drain plate 26 can be movably attached to the bathtub 10 using its top edge. What should be noted here is that the outer small piece 28 is connected to the small hole 4 for the hinge connection.
It is slightly more prominent than 2.46. The purpose of this protrusion is to hide the small holes 42, 46 for the hinge connection.

The fixing member 44 is fixed to the end wall 14 of the bathtub 10 by screws 50, 50, . . . (only one is shown in FIG. 5).
4 and the drainage extension 52 are clamped to the end wall 14 of the bathtub. The above screws 50, 50...
passes through the hole 54 in the fixing member 44 and the overflow outlet 20 in the end wall 14 of the bathtub and into the threaded hole 56 in the drainage extension 52 . A gasket 58 is compressed between the drainage extension 52 and the outer surface of the tub end wall 14. This gasket 58 is for sealing between the drainage extension 52 and the end wall 14 of the bathtub.

The connecting member allows the drain port plate 26 to function as a drain valve control lever as follows (FIGS. 5 and 6). That is,
The Y-shaped connecting member 60 connects the arm 3 at the point 39.
8, this arm 3 is rotatably coupled to
8 is integrally coupled to the small piece 30 inside the drain outlet plate 26. The coupling member 60 is rotatably coupled to the rocker arm 62 at a point 61 at the other end. This rotscar arm 62
is rotatably attached to the fixing member 44 at a point 61, thereby causing the rocker arm 62 to rotate.
can be rotated about a fixed point 64 (i.e., a generally horizontal second axis of rotation). A spring 66 is mounted inside the rocker arm 62 between two washers 68, 70 which act as bungs.

The washer 70 supports an extension 72 integrally extending from the fixing member 44, and
extends through the end wall 14 of the bathtub. The extension portion 72 has an upper surface and a lower surface 74 that act as a cam.
76, the upper and lower surfaces 74, 76 of which are connected to the drain plate (i.e., the lever controlling the valve).
It acts to form two positions.

When the drain plate 26 is in the closed position,
As shown in FIGS. 3 and 6, the washer 7
0 supports the upper surface 74 which acts as the cam.
When the drain plate 26 rotates counterclockwise,

is moved so as to come into contact with the lower cam surface 76, and as shown in FIG. 4, the drain outlet plate (valve control lever) 26 is fixed in the open position. When the valve control lever 28 is closed, the spring 66 is actuated in the same manner as described above to move the washer 70 into contact with the upper cam surface 74. This is similar to when this washer moves past the balance position.

The innermost end of the rocker arm 62 contacts the vertical coupling member (ie, drive member) 78. The length of this connecting member 78 is adjusted by an adjustment arm 80. The lower end of this adjustment arm 80 is connected to a spring 82 . The drain valve 40 is rotatably coupled at a point 84 to a seesaw device 86 which swings back and forth about a fulcrum 88. This seesaw type device 86 can flex inwardly about the point 85, and this flexure causes the drain 1
It can be installed through 8. However, since this seesaw-type device 86 cannot flex outwardly, the seesaw-type device can perform a robust operation due to the seesaw motion when a downward force is applied to the other end.

When the outlet plate 26 is in the closed position as shown in FIG. device 8
away from the unrestrained end 90 of 6. When force is applied to the right side portion of the connecting member 86, the right side portion of the connecting member goes down and the drain valve 4
Close 0. When the drain plate 26 is raised to the open position, the spring 68 presses the washer 70 against the second cam-acting surface 76, causing the spring 82 to press against the unrestrained side of the seesaw-type connecting member 86. The connecting member 86 is rotated counterclockwise about the fulcrum by the force applied by the spring 82, thereby opening the drain valve 40.

What should be noted here, particularly in FIGS. 1 and 2, is that when the drain plate 26 is in the closed position, the drain plate 26 is attached to the vertical bathtub wall 1
is flush with the inner surface of the bath, forming a smooth, nearly continuous surface on which the bather can lean comfortably. A recess 2 in the end wall 14

To assemble the drain valve into the bathtub 10, use the hinge pin 48 to connect the inner piece 3.
0 to the fixed member 44. The drain pipe extensions 102, 52 are connected to corresponding openings 18, 20, respectively. The extension part 10
2 is connected to a flanged piece 104 with screws, and this flanged piece 104 forms the drain port 18. The drain pipe extension 52 is bolted to the fixing member 44 as previously described. At this time, a screwdriver, ie, a screwdriver, is inserted into the holes 51, 51, . The leg portion 105 of the connecting member 78 is inserted into the hole of the adjusting arm 80 and the hole 108 above the nut 110, and is attached to the adjusting arm 80 at the desired position using the bolt 112. This nut 110 is fixed by screwing using a hole 114 on the lower side.

The spring 66 and washers 68 and 70 are attached to the rocker arm 62 and held by a locking pin 69. The vertical connecting member 78 is hung on the hook at the end of the rocker arm 62, and the connecting member 7
8, together with the adjusting arm 80 and the spring 82, is passed under the notch 71 of the fixing member 44, through the opening 20 for the overflow and lowered into the drain pipe 52. Before passing the rocker arm 62 through the fixing member 44, a pin 65 is inserted into the hole 64 of the rocker arm 62. This pin 65 is inserted into the horizontal recess 67 of the fixing member 44.
when the washer 70 contacts one of the surfaces 74, 76 on which the cam acts, the pin 6
5 is press-fitted into the recess of the fixing member 44, and in this way, the rocker arm 62 is attached to the fixing member 44. Then, as already explained,
The outer strip 28 is attached to the inner strip 30 of the take-up roller 26, the seesaw device is connected to the drain valve 40, and the free end 9 of the seesaw device is connected to the drain opening 18. Position it so that it can enter. The separate pieces of the seesaw-type device are deflected inwardly toward each other. This is so that the independent piece can surround the curved portion 100 of the drain pipe 102.

By installing the overflow and drainage control device as described above, the bather only has to rotate the drain plate up and down when he wants to control the drain valve. When the drain valve is closed, the inner surface of the bathtub becomes a smooth, substantially continuous surface on which the bather can rest.

It is clear that changes can be made to the embodiments of the invention described above within the scope of the invention. For example, the plate-like member may be rotated by its side edges or about another axis. Further, the specific function of the lever or other functional member can be changed.
