JPS6016702Y2 - Lid structure for sink drain part - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a lid structure for a drain part of a sink in which a water receptacle is opened in the bottom plate of the tank and a garbage storage container with a drain hole is removably inserted therein.

The lid structure for the drainage section is called Kikuwari, which has radial cuts in the lid body so that the garbage that has been flushed down the sink will flow into the storage container, and the garbage poured into the container will not be visible from the outside. There are lids and lids with a blind structure that close the drainage part and fill the tank with water.

As for the structure of the drainage part to which these lids are attached, the opening diameter of the drainage part relative to the circumferential surface of the lid varies depending on the manufacturer, so the lid manufacturer has to adjust the opening diameter of the drainage part of each manufacturer. It is necessary to manufacture lids with various corresponding dimensions, and molds of various shapes are required, which has the drawback of increasing the cost of the lid alone.

In view of the above-mentioned circumstances, the present invention aims to enable one type of lid to be attached to a plurality of types of drainage sections with different opening diameters by making extremely simple modifications.

Embodiments of the present invention will be described below with reference to the drawings.

1 is a sink, 2 is a water receptacle of the sink 1, 3 is a drainage part attached to the bottom plate 4 of the tank 2, and 5 is the drainage part 3.
It is a lid with a chrysanthemum structure that is removably attached to the lid.

As shown in FIG. 2, the drainage section 3 includes a drainage receiver 7 having a drain pipe 6 connected to its bottom, an annular member 8 screwed onto the upper inner surface of the drainage receiver 7, and the drainage receiver 7. 7
The water receptacle is formed by attaching a packing material 10 having a U-shaped cross section to the hole formed in the recess of the tank bottom plate 4, and attaching the packing material The water receiver is attached to the tank bottom plate 4 by screwing the annular member 8 onto the drain receiver 7 while sandwiching the bottom plate 4 through the water receiver 10.

The garbage storage container 9 has a bottomed cylindrical container body 9a with a handle 11 attached to its bottom, and is provided with a large number of small-diameter drainage holes a at the bottom and local parts. A locking flange 9 facing radially outward on the upper end side of 9a
The flange 9b is placed on the annular seat 12 which is connected to the annular member 8.

The lid 5 for the drainage section 3 is placed on the upper surface of the flange 9b of the garbage storage container 9 with its outer peripheral surface in contact with the inner peripheral surface of the annular member 8. 5 is constructed as follows.

That is, as shown in FIG. 3, FIG. 6, and FIG. Cut b...
. . . is formed near the peripheral edge, and a through hole C is formed at the end of the cut b . . . and at the center of the bottom, respectively.
... is provided, and a reinforcing rib portion e is provided on the lower surface side of the tongue piece d due to the cut b..., and the tongue piece d... The garbage can be poured into the garbage storage container 9 by elastic bending deformation.

Then, the lid body 1 is attached to the peripheral edge 14 of the lid body 13.
3, with deep annular grooves A and B on the bottom side of the peripheral edge and shallow annular groove A' on the top side.
, B' are provided in almost the same phase, and a plurality of (eight in the figure) edges 15 are provided at intervals in the circumferential direction of the deep annular grooves A and H. This is provided.

According to the above configuration, the drainage section 3 differs depending on each manufacturer.
As shown in FIG.
can be attached to the drainage part 3 as is, and for a drainage part 3 whose inner diameter is slightly smaller than that, an outer annular groove A is provided as shown in FIG.

By cutting the portion extending over A' with a suitable tool such as a cutter and removing the peripheral edge 14a and reducing the outer diameter of the lid 5, it can be attached to the drainage part 3 with a small opening diameter. For even smaller drainage sections 3, an inner annular groove B, as shown in FIG.

By cutting off the peripheral edge part 14b by cutting the part extending over B' and making the outer diameter of the lid 5 even smaller, it can be attached to the drainage part 3 with a small opening diameter. A, A', 13. By providing substantially two B' around the center of the lid body, the lid 5 can be made into three parts with different outer diameters.
Of course, as the number of grooves increases, the number of deformations of the lid 5 can be increased.
The number of grooves may be set to one, or a shallow groove A'
, B' may be omitted, the groove depths on the upper and lower surfaces may be made almost the same, or furthermore, the grooves A' and B' on the upper surface may be made deeper.

In addition, the present invention has a cut b at the bottom of the lid body 13.
・Can be applied to lids with a blind structure that do not have a

As detailed above, according to the present invention, on the periphery of the lid body,
By simply providing a groove for cutting the peripheral edge and performing the process of cutting the peripheral edge, a lid obtained by one mold can be processed into lids of at least two different sizes, in other words. For example, it has become possible to attach one type of lid to multiple types of drainage sections with different opening diameters, and this has made it possible to substantially reduce the cost of the lid alone.
