[Problems to be solved by the invention]
An object of the present invention is different from the above-described structure or method, and is particularly suitable for use in a so-called “low floor” bathroom unit having a “low straddle” bathtub installed on a low floor waterproof pan. It is to provide a novel remote-operated drain plug device that can be used.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, the present invention has the following configuration. That is, the present invention firstly
A remote-operated drainage plug device that allows drainage from the bathtub 1 to flow into a drainage trap section 3 of a waterproof pan 2 that is connected (installed below the bathtub 1) via a connection tube 4,
The remote-operated drain plug device was connected to a bathtub drain plug (opening / closing lid) 6, a cable (also referred to as a wire, a release, etc.) 7 for transmitting the opening and closing of the bathtub drain plug 6, and the other end of the cable 7. And a remote control unit,
The cable 7 passes through a cable introduction tube 8 integrally formed with the connection tube 4 and projecting obliquely upward, from obliquely above, through a lower portion or a lower portion of the connection tube 4, and inside the cylindrical portion 4 a of the connection tube 4. It is a remotely operated drain plug device that faces upward and is connected to the lower part of the bathtub drain plug 6.
[0006]
Here, the connecting tube 4 is preferably an integral component of the cylindrical portion 4a and the cable introducing tube 8 rising obliquely upward from the lower portion of the cylindrical portion 4a. At this time, the inclination angle of the cable introduction tube 8 rising obliquely upward from the lower portion of the cylindrical portion 4a is set to an angle at which the cable introduction tube 8 itself or a hose connected thereto does not hit the bottom of the bathtub. From) about 15 ° to 45 °. The upper part of the connection tube 4 is preferably formed in a flange shape. The connection tube 4 can be made by molding a synthetic resin. Further, an adhesive or sticky adhesive member (packing) may be attached to the peripheral edge on the bottom surface side of the connection cylinder 4 with an adhesive tape or the like in advance.
[0007]
As the adhesive member (packing), a member having a good sealing property at the time of pressure bonding is preferable. An adhesive member (packing) made of a foam such as foamed rubber or urethane foam is more preferable because it can absorb the deflection at the bottom of the bathtub when the bathtub is full, tolerance of molded articles, assembly error of the bathroom unit, and the like.
[0008]
The present invention also provides a bathtub provided with the above-mentioned remotely operated drain plug device. That is, a bathtub with a remote-operated drain plug device provided with a remote-operated drain plug device that allows bath-tub drainage to flow into a drain trap unit 3 (of a waterproof pan) connected via a connection tube 4, wherein the remote-operated drain plug device is Is composed of a bathtub drain plug, a cable 7 for transmitting the opening and closing of the bathtub drain plug, and a remote control unit connected to the other end of the cable 7. A remote-operated drainage plug device that is diagonally above the projecting cable introduction tube 8, passes through the lower or lower part of the connection tube 4, upwards in the cylindrical portion of the connection tube 4, and connects to the lower part of the bathtub drainage plug It is a bathtub with.
[0009]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the present invention will be described more specifically with reference to the accompanying drawings. FIG. 1 is a cross-sectional view of a connecting portion of a bathtub drain plug, a waterproof pan, and a drain trap when a remote-controlled drain plug device of the present invention is used, and FIG. 3 is a partial cross-sectional view (enlarged view) of FIG. FIG. 3 shows a bottom view of the connection tube with an adhesive member used in the present invention. As can be seen from FIG. 3, a large hole (ie, bathtub drain hole 4c) and a small hole (ie, cable introduction hole 4d) are formed on the bottom side of the connection tube. Further, FIG. 4 shows an explanatory view for explaining the attachment of the connection tube to the bathtub.
[0010]
The mounting of the remotely operated drain plug device of the present invention on the bathtub 1 will be described in order with reference to FIGS. 1, 2 and 4.
<Bath drain section>
A drainage flange 9 is inserted from above into an opening formed on a predetermined bottom surface of the bathtub 1, a connection tube 4 having a packing 5 attached to the bottom surface side is fitted from the backside of the bathtub, and the drainage flange 9 is rotated and tightened. Both are fixed (FIG. 4).
[0011]
<Upper edge of bathtub (remote control unit)>
On the other hand, the flange for the remote control unit is inserted into an opening formed at an appropriate position on the upper edge surface of the bathtub, and the tightening nut is rotated from below to fix the flange for the remote control unit (not shown).
[0012]
<Hose installation>
Using a transparent (or translucent) hose with a connection fitting having a female screw attached to one end, the remote control unit is connected to the bathtub drain port (the cable introduction tube 8 in the connection tube 4). Here, one end side of the hose (the upper tub surface side of the bathtub) is rotationally fastened, and the other end side (the connection cylinder side) is plugged and fixed.
[0013]
<Cable insertion / introduction>
With the opposite end of the cable 7 having a push button at one end, the cable 7 is inserted into the flange for the remote control unit from above, and pushed until the tip of the cable 7 comes under the connection tube 4. Next, the tip of the cable 7 is guided upward in the cylindrical portion 4a (of the connection tube 4), and the tip of the cable 7 is pulled up to the bathtub drain.
[0014]
<Mounting of cable fixing member>
After the cable tip pulled up to the bathtub drain is passed through the center of the cable fixing member in the inside of the bathtub, the cable fixing member is rotated to tighten the cable 7.
[0015]
<Cable fixing member and cable fixing>
The cable fixing member is fitted into the drain of the bathtub, and pressed down from the top until it snaps.
[0016]
<Installation of bathtub drain plug>
The center of the bathtub drain plug (opening / closing lid) 6 is aligned with the end of the cable 7 and pressed down from above. By the above operation, a bathtub with a remotely operated drain plug is completed.
[0017]
<Placement of a bathtub with a remotely operated drain plug on a waterproof pan>
The bathtub with the remotely operated drain plug is dropped from above (placed on a waterproof pan) so that the drain port of the bathtub matches the drain port of the drain trap. Then, the space between the bathtub drain port (connecting tube 4) and the drain trap unit 3 is hermetically sealed by the adhesive or sticky packing 6 by the weight of the bathtub. However, it is confirmed that the packing 5 is compressed between the connection tube 4 and the drain trap portion 3.
[0018]
[Action and effect]
(1) Since the cable is guided obliquely upward and outward (below the bathtub) in the cable introduction tube formed in the connection tube and projecting obliquely upward, the cable does not contact the drain trap member in the height direction. . (2) Compare the remote-operated drainage plug device of the present invention with a method of passing a cable for opening and closing a bathtub drainage plug through a drainage trap portion and then penetrating a lid immediately above the drainage trap portion upward. According to the present invention, the bending rate (R) of the cable can be made large, and the operation of the cable becomes smooth.
(3) The height of the connecting member can be reduced as compared with the method of providing the cable lead-out hole in the horizontal direction, and therefore, a bathtub (or bathroom unit) having a low straddling height can be provided.
(4) The cable can be arranged without penetrating the waterproof pan as compared with a method of passing the cable through the drain pipe (connection part) through the drain trap part.
(5) A remote control drain plug device can be attached to a bathtub in advance at a factory to provide a bathtub with a remote control drain plug device. If this is used, the remote control drain plug device can be attached to the bathtub at the installation site (complicated). ) Saves time.
