It is related to the configuration of the operation unit of.

Conventionally, in order to treat the drainage generated inside the tank body such as a bathtub or a washbasin, a drainage port is provided on the bottom surface of the tank body, etc., and the drainage is discharged from this drainage port to the sewage side via a piping member. Is widely known. In addition, there is a method of collecting water in the tank by arranging the valve body so as to cover the drain port, and opening the drain port by raising the valve body and separating it from the drain port. A remote-operated drain plug device that opens and closes the drain port by raising and lowering is known by operating a position away from the valve body and the drain port, for example, an operation unit provided at the edge of the tank body or above the side surface of the tank body. There is.
Widely known remote-controlled drain plug devices include a drain port provided on the bottom surface of the tank body, a valve body arranged above the drain port body, and a valve body as described in Patent Document 1. There is known a remote-controlled drain plug device that consists of an operation unit located at a separated position and that opens and closes a drain port by remote control by operating the operation unit.
More specifically, the remote-controlled drain plug device described in Patent Document 1 includes a drain port main body having a cylindrical shape and a drain port on the upper edge.
A mechanism part consisting of a shaft part called a lock shaft, which is inside the drainage port body and is attached directly under the drainage port, and a cylindrical mechanism body part that houses the lock shaft inside. ,
A disk-shaped valve body that opens and closes the drainage port, which connects the lock shaft to the center of the lower surface,
A joint member connected to the lower end of the drainage port body and having an insertion portion for inserting a release wire, which will be described later, and a joint member.
A shaft-shaped operating body equipped with a knob for pushing operation,
A release wire composed of a cylindrical outer tube as an operation transmission member for transmitting the operation of the operating body, and an inner wire advancing and retreating in the outer tube.
It consists of.
The inner wire and the release wire are provided with flexibility in the side surface direction and rigidity in the axial direction, respectively.
The mechanism part has a structure called a thrust lock mechanism, and when the construction is completed, the release wire is configured to operate the lock shaft, and each time the operating body is pushed, the lock shaft is fixed in an raised state / It is configured to release the fixing and lower the lock axis alternately.
Further, in this conventional example, for the purpose of improving workability, a part of the water discharge fitting that discharges water to the tank body without providing a guide member for the operation body called the operation unit main body, and a guide on the back side. An operation through hole (guide column) is provided as an opening for the operation, and the operation body is arranged in the operation through hole so as to be able to move forward and backward. That is, the water spouting metal fitting is configured as the main body of the operation unit.
The bathtub as a bathtub to which these remote-controlled drainage plug devices are installed has an opening at the top and a mounting hole for attaching the drainage port body at the bottom, and the flange of the bathtub near the upper edge of the opening or the bathtub. The deck is provided with metal fitting mounting holes for mounting water discharge metal fittings.

The remote-controlled drain plug device composed of the above-mentioned members is installed in the bathtub, which is a tank body, as follows.
First, attach the drainage port body to the mounting hole of the bathtub, and attach the water discharge fitting to the fitting mounting hole.
Next, one end of the release wire is inserted from the branch pipe portion of the joint member, the release wire is pulled up from the upstream end portion, and then the release wire is connected to the mechanism portion.
By this connection, each time the inner wire advances and retreats in the outer tube to operate the lock shaft of the mechanism part, the mechanism part alternately repeats fixing / unlocking and lowering the lock shaft with the lock shaft raised. You will be able to do it.

Along with this, the valve body also descends, moves to a position where the valve body comes into contact with the drain port, and closes the drain port.
After that, by pushing the knob of the operation unit, the drainage port can be opened and closed by remote control at a position away from the valve body.
Further, in this conventional example, by providing an operation through hole for arranging the operation body in the water discharge metal fitting, the operation unit main body as a receiving member of the operation body is separately prepared, or the operation unit main body is placed in the vicinity of the tank body. It is not necessary to provide a through hole for the main body of the operation unit for arranging, and it is possible to save the trouble of drilling and mounting.

Jitsukaihei 6-355370

In the remote-controlled drain plug device described in Patent Document 1, the operating body is composed of a rod-shaped member having a knob at the end, the upper end is arranged on a water discharge fitting for operation, and the lower end transmits the operation. It is configured to connect a release wire as an operation transmission member.
Therefore, the operating body is arranged so as to vertically penetrate the flange surface of the bathtub to which the water spouting metal fitting is attached and the metal fitting mounting hole provided in the deck portion.
Here, considering the position of the water spouting metal fitting for arranging the operating body, there is a water spouting port in front of the water spouting metal fitting, and the operating body arranged in the vertical direction interferes with the water spouting port. Therefore, the operating body cannot be placed in front of the water discharge fitting.
Further, on the left and right sides of the water discharge fitting, there are handles for opening and closing water discharged from the water discharge port and for adjusting the amount of water, and the operating body arranged in the vertical direction interferes with the handle for water discharge operation. Therefore, the operating body cannot be placed on the side surface of the water discharge fitting. There is also a water discharge fitting equipped with a water discharge operation handle on only one side, but in this case, the design of the water discharge operation handle and the knob part is significantly different, and the operation direction is also the operation while the water discharge operation handle is a rotation operation. Since the body is a push-pull operation or a push operation up and down, and the shape and the operation method are completely different, there is a problem that the design and operability are very poor.
As a result, when arranging the operating body on the water spouting metal fitting, the operating body must be arranged on the back side of the water spouting metal fitting, and the user of the remote-controlled drain plug device bypasses the main body part of the water spouting metal fitting. It was awkward to handle because I had to reach behind.
Further, the water spouting metal fitting has a structure that extends upward from at least the mounting position, is inverted, and the end portion on the water spouting port side faces downward, and both the water spouting metal fitting and the operating body are arranged in the vertical direction from the metal fitting mounting hole. The Rukoto. As described above, since both the water spouting metal fitting and the operating body extend upward from the metal fitting mounting hole, the water spouting metal fitting becomes an obstacle when the operating body is to be operated.
If the operating body is placed at a position different from the water discharge metal fittings and operated, the above-mentioned problems can be solved, but in that case, the metal fitting mounting holes are provided in the flange portion of the bathtub or the bathtub deck portion. It is necessary to provide a hole for the operation unit separately.
In this case, it is necessary to process the bathtub, wash basin, and other tank bodies and decks on the premise that a remote-controlled drain plug device will be used in advance, which saves time and effort during design and construction. It will increase.

Further, in recent years, in the wash basin, a wash basin having a structure in which most of the bath body of the wash basin, at least about 80% of the total height, is located on the upper surface of the pedestal on which the wash basin is installed, which is called a vessel type. The number of units is increasing.
In the conventional wash basin, the bath body portion of the wash basin is arranged below the upper surface of the pedestal with respect to the opening provided in the pedestal, and the flange portion provided on the peripheral edge of the pedestal body is locked to the opening of the pedestal. A structure called an embedded type,
In contrast to the structure called the under-counter type, where the opening of the washbasin is placed below the opening provided on the pedestal, and the entire tank body of the washbasin is placed below the upper surface (counter) of the pedestal.
In the vessel type wash basin, the wash basin, including the tank body part, is almost entirely placed on the pedestal, and there is no part placed below the upper surface of the pedestal, or the drainage port at the lower end of the tank body. It is a structure that is arranged below the upper surface of the pedestal only in the vicinity of and its vicinity.
In the case of this vessel type wash basin, most of the tank body part is placed above the upper surface of the pedestal, so there is a higher degree of freedom in selecting and arranging the wash basin part compared to the embedded type and under counter type. ..
In detail, in the embedded type and the under counter type, it is necessary to match the opening of the pedestal and the opening of the washbasin, so it is necessary to adjust both the pedestal and the washbasin from the design stage, whereas in the vessel type The structure is such that the washbasin including the tank body is simply placed on the pedestal, and there is no need to accurately match the opening of the pedestal with the opening of the washbasin.
Therefore, it has an advantage that the washbasin can be freely selected according to the preference of the user, but on the other hand, there is a problem of how to form a hole for the operation part. If both the washbasin and the pedestal are provided with mounting holes for the operation part, one of the holes remains open, and there is a problem that the design is poor. On the other hand, if both the washbasin and the pedestal do not have mounting holes for the operation unit, it becomes difficult to adopt the remote-controlled drain plug device itself. It is conceivable to use a washbasin without holes for the operation part and to make holes in the pedestal without holes for the operation part with a drill etc., but if the pedestal is pottery such as tiles, these methods cannot be adopted. There is also.
The present invention has been invented in view of the above problems, and in a remote-controlled drain plug device, the degree of freedom in the arrangement, configuration, and operation method of the operation unit is increased, and particularly when the operation unit is arranged in the water discharge fitting. It relates to a remote-controlled drain plug device that improves usability.

Further, the connection points between the operation body 4 and the operation transmission member in the embodiments of FIGS. 10 and 11 are connection points between the knob portion 4a and the inner wire 5b. Therefore, since the knob portion 4a is connected to the inner wire 5b above the upper surface of the pedestal portion C1, the remote-controlled drain plug device of the embodiment of FIGS. 10 and 11 has the operation transmission member and the operation body 4. This is a remote-controlled drain plug device in which the connection point is provided on the front side of the operation unit mounting surface.
In this embodiment, the position of the knob portion 4a of the operating body 4 is the front surface of the water spouting metal fitting K, but the knob portion 4a of the operating body 4 is arranged with respect to the pipe body portion of the water spouting metal fitting K extending vertically. Since the operation direction is the front-rear direction, the operation of the operating body 4 is not interfered with by the water discharge fitting K, and the operation can be smoothly performed.

Further, although each of the above embodiments is a remote-controlled drain plug device adopted for the wash basin, the present invention is not limited to the above embodiment, and the present invention is not limited to the above embodiment, and any tank body such as a bathtub or a sink can be used. You may adopt it.
Further, in the above embodiment, the operation unit 3 is also used by the water discharge fitting K, but the present invention is not limited to the above embodiment, as in the operation unit main body 9 shown in FIGS. 12 and 13. , The water spouting metal fitting and the operation unit main body 9 may be separated from each other.

The present invention relates to a remote-controlled drain plug device that opens and closes a drain port of a tank body by operating an operation unit provided at a position away from the drain port, and more particularly, a remote-controlled drain plug device. It is related to the configuration of the operation unit of.

Conventionally, in order to treat the drainage generated inside the tank body such as a bathtub or a washbasin, a drainage port is provided on the bottom surface of the tank body, etc., and the drainage is discharged from this drainage port to the sewage side via a piping member. Is widely known. In addition, there is a method of collecting water in the tank by arranging the valve body so as to cover the drain port, and opening the drain port by raising the valve body and separating it from the drain port. A remote-operated drain plug device that opens and closes the drain port by raising and lowering is known by operating a position away from the valve body and the drain port, for example, an operation unit provided at the edge of the tank body or above the side surface of the tank body. There is.
Widely known remote-controlled drain plug devices include a drain port provided on the bottom surface of the tank body, a valve body arranged above the drain port body, and a valve body as described in Patent Document 1. There is known a remote-controlled drain plug device that consists of an operation unit located at a separated position and that opens and closes a drain port by remote control by operating the operation unit.
More specifically, the remote-operated drain plug device described in Patent Document 1 has a drain port main body having a tubular shape and a drain port on the upper edge, and an inside of the drain port main body, which is directly below the drain port. A mechanism part consisting of a shaft part called a lock shaft that is attached to a position, a tubular mechanism body part that houses the lock shaft inside, and a mechanism part that connects the lock shaft to the center of the lower surface, opens and closes the drainage port. Operation with a disk-shaped valve body, a joint member having an insertion part for inserting a release wire, which will be described later, connected to the lower end of the drainage port body, and a shaft-shaped operation body having a knob part for pushing operation. It is composed of a release wire composed of a tubular outer tube as an operation transmission member for transmitting the operation of the body and an inner wire advancing and retreating in the outer tube.
The inner wire and the release wire are provided with flexibility in the side surface direction and rigidity in the axial direction, respectively.
The mechanism part has a structure called a thrust lock mechanism, and when the construction is completed, the release wire is configured to operate the lock shaft, and each time the operating body is pushed, the lock shaft is fixed in an raised state / It is configured to release the fixing and lower the lock axis alternately.
Further, in this conventional example, for the purpose of improving workability, a part of the water discharge fitting that discharges water to the tank body without providing a guide member for the operation body called the operation unit main body, and a guide on the back side. An operation through hole (guide column) is provided as an opening for the operation, and the operation body is arranged in the operation through hole so as to be able to move forward and backward. That is, the water spouting metal fitting is configured as the main body of the operation unit. The bathtub as a bathtub to which these remote-controlled drainage plug devices are installed has an opening at the top and a mounting hole for attaching the drainage port body at the bottom, and the flange of the bathtub near the upper edge of the opening or the bathtub. The deck is provided with metal fitting mounting holes for mounting water discharge metal fittings.

The remote-controlled drain plug device composed of the above-mentioned members is installed in the bathtub, which is a tank body, as follows.
First, attach the drainage port body to the mounting hole of the bathtub, and attach the water discharge fitting to the fitting mounting hole.
Next, one end of the release wire is inserted from the branch pipe portion of the joint member, the release wire is pulled up from the upstream end portion, and then the release wire is connected to the mechanism portion.
By this connection, each time the inner wire advances and retreats in the outer tube to operate the lock shaft of the mechanism part, the mechanism part alternately repeats fixing / unlocking and lowering the lock shaft with the lock shaft raised. You will be able to do it. Next, the upstream end of the joint member is connected to the lower end of the drainage port main body.
Next, the operating body is inserted through the operating through hole of the water discharge fitting. Next, the other end of the release wire is connected to the operating body and the water discharge fitting which is the main body of the operating unit. At the time of this connection, the end of the inner wire is connected and fixed to the lower end of the operating body, and the end of the outer tube is connected and fixed to the water discharge fitting.
Further, the valve body is connected to the lock shaft of the mechanism portion, and the construction of the conventional remote-controlled drain plug device is completed.

When using the remote-controlled drain plug device configured as described above, the valve body is first lowered so that the valve body closes the drain port. At this time, the lock shaft is released from the fixed position and is in the lowered position.
When a push operation is performed on the knob part of the operating body from this state, the inner wire moves forward in the outer tube toward the drain port side by pushing the operating body, and the lock shaft of the mechanism part is pushed up by the inner wire. As it rises, the mechanism part fixes the lock shaft in a raised state.
Therefore, the valve body provided at the tip of the lock shaft also rises and separates from the drainage port, and is fixed in a state where the drainage port is open. When there is hot water in the bathtub, the hot water is discharged as drainage from the drainage port through the inside of the drainage port main body and the inside of the joint member to the pipe on the sewage side.
When the push operation is performed again on the knob portion of the operation portion, the push operation is transmitted to the lock shaft again via the inner wire, the lock shaft is released from being fixed in the raised state, and the lock shaft is lowered by its own weight or the like. Along with this, the valve body also descends, moves to a position where the valve body comes into contact with the drain port, and closes the drain port.
After that, by pushing the knob of the operation unit, the drainage port can be opened and closed by remote control at a position away from the valve body.
Further, in this conventional example, by providing an operation through hole for arranging the operation body in the water discharge metal fitting, the operation unit main body as a receiving member of the operation body is separately prepared, or the operation unit main body is placed in the vicinity of the tank body. It is not necessary to provide a through hole for the main body of the operation unit for arranging, and it is possible to save the trouble of drilling and mounting.

Jitsukaihei 6-355370

In the remote-controlled drain plug device described in Patent Document 1, the operating body is composed of a rod-shaped member having a knob at the end, the upper end is arranged on a water discharge fitting for operation, and the lower end transmits the operation. It is configured to connect a release wire as an operation transmission member.
Therefore, the operating body is arranged so as to vertically penetrate the metal fitting mounting holes provided in the flange portion and the deck portion of the bathtub to which the water discharge fitting is attached.
Here, considering the position of the water spouting metal fitting for arranging the operating body, there is a water spouting port in front of the water spouting metal fitting, and the operating body arranged in the vertical direction interferes with the water spouting port. Therefore, the operating body cannot be placed in front of the water discharge fitting.
Further, on the left and right sides of the water discharge fitting, there are handles for opening and closing water discharged from the water discharge port and for adjusting the amount of water, and the operating body arranged in the vertical direction interferes with the handle for water discharge operation. Therefore, the operating body cannot be placed on the side surface of the water discharge fitting. There is also a water discharge fitting equipped with a water discharge operation handle on only one side, but in this case, the design of the water discharge operation handle and the knob part is significantly different, and the operation direction is also the operation while the water discharge operation handle is a rotation operation. Since the body is a push-pull operation or a push operation up and down, and the shape and the operation method are completely different, there is a problem that the design and operability are very poor.
As a result, when arranging the operating body on the water spouting metal fitting, the operating body must be arranged on the back side of the water spouting metal fitting, and the user of the remote-controlled drain plug device bypasses the main body part of the water spouting metal fitting. It was awkward to handle because I had to reach behind.
Further, the water spouting metal fitting has a structure that extends upward from at least the mounting position, is inverted, and the end portion on the water spouting port side faces downward, and both the water spouting metal fitting and the operating body are arranged in the vertical direction from the metal fitting mounting hole. The Rukoto. As described above, since both the water spouting metal fitting and the operating body extend upward from the metal fitting mounting hole, the water spouting metal fitting becomes an obstacle when the operating body is to be operated.
If the operating body is placed at a position different from the water discharge metal fittings and operated, the above-mentioned problems can be solved, but in that case, the metal fitting mounting holes are provided in the flange portion of the bathtub or the bathtub deck portion. It is necessary to provide a hole for the operation unit separately.
In this case, it is necessary to process the bathtub, wash basin, and other tank bodies and decks on the premise that a remote-controlled drain plug device will be used in advance, which saves time and effort during design and construction. It will increase.

Further, in recent years, in the wash basin, a wash basin having a structure in which most of the bath body of the wash basin, at least about 80% of the total height, is located on the upper surface of the pedestal on which the wash basin is installed, which is called a vessel type. The number of units is increasing.
In the conventional wash basin, the bath body portion of the wash basin is arranged below the upper surface of the pedestal with respect to the opening provided in the pedestal, and the flange portion provided on the peripheral edge of the pedestal body is locked to the opening of the pedestal. A structure called an embedded type, or a structure called an under counter type, in which the opening of the washbasin is arranged below the opening provided on the pedestal, and the entire tank body part of the washbasin is arranged below the upper surface (counter) of the pedestal. On the other hand, in the vessel type wash basin, almost the entire wash basin including the tank body part is placed on the pedestal, and there is no part placed below the upper surface of the pedestal, or the tank. It is a structure in which only the drainage port at the lower end of the body and its vicinity are arranged below the upper surface of the pedestal. In the case of this vessel type wash basin, most of the tank body part is placed above the upper surface of the pedestal, so there is a higher degree of freedom in selecting and arranging the wash basin part compared to the embedded type and under counter type. ..
In detail, in the embedded type and the under counter type, it is necessary to match the opening of the pedestal and the opening of the washbasin, so it is necessary to adjust both the pedestal and the washbasin from the design stage, whereas in the vessel type The structure is such that the washbasin including the tank body is simply placed on the pedestal, and there is no need to accurately match the opening of the pedestal with the opening of the washbasin. Therefore, it has an advantage that the washbasin can be freely selected according to the preference of the user, but on the other hand, there is a problem of how to form a hole for the operation part. If both the washbasin and the pedestal are provided with mounting holes for the operation unit, one of the holes remains open, which causes problems such as poor design. On the other hand, if both the washbasin and the pedestal do not have mounting holes for the operation unit, it becomes difficult to adopt the remote-controlled drain plug device itself. It is conceivable to use a washbasin without holes for the operation part and to make holes in the pedestal without holes for the operation part with a drill etc., but if the pedestal is pottery such as tiles, these methods cannot be adopted. There is also.
The present invention has been invented in view of the above problems, and in a remote-controlled drain plug device, the degree of freedom in the arrangement, configuration, and operation method of the operation unit is increased, and particularly when the operation unit is arranged in the water discharge fitting. It relates to a remote-controlled drain plug device that improves usability.

The term "front side of the operation unit mounting surface" as used herein is an expression indicating the side closer to the place where the operation unit is operated when the user normally uses the remote-controlled drain plug device.
For example, when the operation unit is attached to the inner side surface of the tank body and the operation is performed from the inside of the tank body, the inner surface side of the tank body is the front side, the operation unit is attached to the outer side surface of the tank body, and the operation is performed from the outside of the tank body. When performing, the outer surface side of the tank body is the front side, and the work part is attached near the horizontal plane around the tank body, such as the horizontal plane around the opening of the tank body or on the pedestal on which the tank body is placed. When operating from above, the upper surface side of the peripheral edge of the tank body is the front side, and when operating from the front of the vertical surface, attach the operation unit to a vertical surface such as a vertical panel provided near the tank body. The front side (front side of the hand) of the vertical surface is the front side.

In the present invention according to claim 1, the operation body is arranged by providing the connection point between the operation body of the operation unit of the remote-controlled drain plug device and the operation transmission member on the front side of the surface on which the operation unit is attached. I was able to increase the degree of freedom in the layout and operation method. Specifically, for example, the operation body is arranged horizontally with respect to the surface to which the operation unit is attached, and the operation body is moved horizontally with respect to the surface to which the operation unit is attached to operate the operation unit. It is not necessary to arrange or operate the operation body toward the operation unit mounting hole, and the degree of freedom in arrangement and operation method can be increased.
