Another object of the present invention is to provide a sink drainage system that can be connected between the drain pipe and the tub of the plumbing fixture without using a manual tool.

Still another object of the present invention is to provide a drainage device for a basin that can be assembled easily and quickly. Another object of the present invention is to provide a sink for drainage operation is reliable. Other objects of the present invention will become apparent from the following description of the preferred embodiments of the present invention.

The drainage device shown in FIGS. 1-9 is composed of a drain pipe 10, a pop-up plug 12, a support nut 14, a lifting rod 16, a support clamp 18, and a link 20. It is connected between the drain pipe (not shown) and the basin 22 of the plumbing fixture of a building or home.

The basin 22 has a bottom wall 24 and an overflow effluent drainage formed by the lower partition wall 28, and an opening 30 is formed in the side wall 32 of the basin at a predetermined height from the bottom wall 24. The water flowing out from the basin is discharged. In addition, a drain hole 34 is formed in the bottom wall 24 and the partition wall 28. A faucet cover plate 36 is installed on the rear upper flange 38 of the basin 22, which covers the valve members of the faucet (not shown) that are installed in the basin 22. Used to surround The specific structure of the accessory parts of the basin, such as the faucet and cover plate, can vary depending on the shape of the basin. The drainage pipe 10 of the drainage assembly consists of sidewalls 40 forming a liquid flow path 42, with a flanged seat 44 mounted on top thereof, just below the sheet 44. The overflow effluent outlet 46 is formed. In addition, the side wall opening 50 formed by an annular shoulder 52 is formed on the outer surface of the drainage pipe, and the side wall 40 is formed below the spiral 48 at a space spaced below the effluent outlet 46. ) Is formed, and a pair of shoulders 54 are formed on the outer surface of the side wall 40.

The drain pipe 10 as described above has a uniform diameter, and is inserted downward through the drain hole 34 of the tub 22 until the sheet 44 of the drain pipe is supported by the bottom wall 24 of the tub. Can be. A seal, such as a flexible seal ring 56 or putty, is disposed between the sheet 44 and the basin bottom wall 24 around the drain 34.

The support nut 14 has a drain pipe 10 disposed above the lower end 58 and is coupled to the spiral 48 of the drain pipe. The nut 14 is provided with a 0-ring 60, which is pressed against the bulkhead partition 28 around the drain 34 when the nut is tightened to form a seal. Tightening of (14) can be performed manually because the protrusion 62 is provided in the nut, and the sealing rings 56 and 60 are crimped | bonded to the basin 22 by the tightening rotation of such a nut 14. It is sealed. The outflow drain 46 of the drain pipe 10 is positioned to be disposed between the bottom wall 24 and the partition wall 28. The spiral 48 of the drain pipe 10 is spaced apart from the lower partition 28 of the basin, and the outer surface is smoothed at the drain of the basin. Thus, the 0-ring 60 reliably provides a seal of the drain to the basin drain without requiring a putty or other type of seal.

The popup stopper 12 is slidably inserted into the conduit 42 of the drain pipe. The stopper 12 has an annular cap 64 in hermetic contact on the periphery of the sheet 44 of the drainpipe when the stopper is positioned at the lowest position in the drainpipe. The stopper 12 is moved by the elevating rod 16 between the lower closed position and the upper open position as shown in FIGS. 5 and 9 degrees. A spherical bearing portion 66 is formed at one end of the elevating rod 16, and an extension 68 disposed coaxially with the elevating rod is formed outside the spherical bearing portion 66. The other end of the elevating rod 16 is pivotally connected to the end 72 of the link 20 by a pin 70.

The support clamp 18 is composed of a pair of arms 74 connected by a web portion 76, and an inwardly curved flange 78 is formed at an end of each arm 74. . The web portion 76 of the support clamp 18 has an opening 80 formed by an annular inner shoulder 82 and a cylindrical sidewall 84. Arms 74 are located on both sides of the elevating rod 16 extending through the opening 80. The bearing surface 66 of the lifting rod 16 is located in the opening 80 so as to be in contact with the shoulder 82 of the support clamp.

With the extension portion 68 of the elevating rod extending into the side wall opening 50 of the drain pipe 10, the support clamp 18 is pressed against the side wall 40 of the drain pipe, so that the arm 74 of the clamp is drained. By slightly opening around the side wall of the clamp, the flange 78 of the clamp can be firmly snapped to the shoulder 54 of the drain pipe as shown in FIG.

A 0-ring 86 is located in the shoulder 52 of the sidewall opening 50. When the support clamp 18 is coupled to the drain pipe 10, a bare portion 66 is pressed against the 0-ring 86. Thus, a seal is achieved.

In this state, the lifting rod 16 is able to pivot with respect to the drain pipe 10 in the support clamp 18 while maintaining hermetic contact with the drain pipe. The bottom 88 of the stopper 12 comes into contact with the extension 68 of the lifting rod 16 in the conduit 42, so that the stopper 12 opens as the lifting rod 16 moves up and down. It moves between the position and the closed position.

The lifting rod 16 may attach the drain pipe 10 to the basin and then connect it to the drain pipe 10 without using a tool. The elevating rod 16 is pivotally connected to the elevating rod at the end 72 and has an upper end 90 extending upwardly beyond the opening 88 and the cover plate 36 of the basin 22. Is moved by 20). The link 20 consists of two parts, one of which is a rod 92 and the other of which is a bar 94, wherein the rod 92 and the bar 94 are connected to each other by adjustable pivot connectors. The bar 94 is provided with a yoke 96 at the opposite end of the lifting rod 16, and the yoke forms a socket 98 configured by dividing the bearing portion.

A shaft hole 104 is formed through the ball member 100, and one side of the ball member is cut out toward the shaft hole. Thus, when the lateral compression force is applied to the ball member from the socket 98, the diameter of the shaft hole is reduced. The screw 106 is inserted into the yoke 96 so as not to rotate, and the wheel 108 is screwed to the exposed end of the screw 106. Thus, rotating the wheel 108 relative to the screw 106 causes the two halves of the yoke 96 to approach each other, thereby squeezing the ball member 100, thus reducing the cross-sectional area of the shaft hole 104. .

One end of the rod 92 is slidably inserted into the shaft hole 104 of the ball member 100. Thus, the rod 92 can be positioned such that its upper end 90 selectively protrudes from the top of the basin 22 and the cover plate 36. Once the rod 92 is properly positioned in the tub 22 vertically, the wheel 108 is tightened against the screw 106 to retract the ball member 100, thereby securing the rod to the ball member. The yoke 96 is tightened relative to the ball member 100 to prevent the ball member and the rod 92 received therefrom from pivoting about the bar 94. The protrusion 102 of the ball member 100 is in pressure contact with the inner surface of the socket 98, thereby promoting engagement between the ball member and the yoke 96. In this way, the rod 92 can be arranged to move in parallel with the axis of the drain pipe 10, allowing the lifting rod 16 to perform a smooth up and down pivot movement.

The drain pipe 10 excluding the sheet 44, the stopper 12, the support nut 14, the lift rod 16, and the bar 94 of the link 20 except the cap 64 may be formed of a plastic material. . The ball member 94, which provides a pivotal connection between the rod 20 of the link 100 and the bar 98, is adapted to facilitate pressure contact between the protrusion 96 of the ball member and the inner surface of the socket 10. It is preferable that the yoke 34 of 58 be formed of a harder material. Although not shown, suitable conduit pipes or other fittings are connected to the bottom 10 of the drain pipe 22 to connect the drain pipe to the plumbing fixture.

As mentioned above, although the embodiment of the present invention has been described, the present invention is not limited to the above-described embodiment and may be changed within the scope of the appended claims.
