Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improved sink basket that is inserted into the upper space of the drainage section of the sink.

A sink basket usually consists of a basket holder and a draining basket, and is inserted into the upper space of the drain section of the sink.

However, the opening diameter of the drain section differs depending on the manufacturer of the sink, and when connecting the drain section to the bottom of the drain section, it is common to connect it through a trap, but it depends on the size of the trap. The depth of the upper space of the drainage section may vary, and the user, the general consumer, must measure the opening diameter and depth of the drainage section in advance and purchase a sink basket with dimensions that match that. However, depending on these dimensions, they may not be commercially available, which is somewhat inconvenient.

The present invention was proposed in view of the above-mentioned issues, and allows one type of sink basket to be inserted into multiple types of drains with different opening diameters and depths by making extremely simple modifications. This is what I did.

Hereinafter, embodiments of the present invention will be described based on the drawings.

First, the structure of the sink into which the sink basket of the present invention is inserted and its drainage section will be explained with reference to FIGS. 1 and 2.

In Fig. 1, 1 is a sink, 2 is a water tank of the sink 1, 3 is a drainage part attached to the bottom plate 4 of the water tank 2, and 5 is a chrysanthemum cracking structure that is detachably attached to the drainage part 3. It is the lid of

The drainage section 3 is connected to a bottom plate 4 as shown in FIG.
A packing material 6 having a U-shaped cross section is attached to the hole formed in the recess, and an annular member 8 is screwed onto the drainage receiver 7 while holding the bottom plate 4 through the packing material 6. The bottom of the drain receptacle 7 is connected to a drain pipe 12 via a trap 11 consisting of a bowl body 9 provided with a notch 9' and an inner cylinder 10. 3' is an upper space part of the drainage part 3.

The sink basket 20 according to the present invention, as shown in FIG.
It consists of

The basket holder 30 includes a trunk body 31 and a trunk body 31.
It consists of a flange 32 extending to the flange 32. On the outer peripheral edge of the flange 32, for example, two grooves 33, 34 and a protrusion 35 are provided concentrically, as shown in FIGS. 3A and 4. In the outer groove 33, a plurality of holes 33A (eight holes in the figure) are provided at equal intervals in the circumferential direction, and the inner groove 34
The protruding portion 35 is provided so as to be in contact with. A plurality of notches 36 (four in this embodiment) are provided in the trunk body 31 in the circumferential direction. This notch 36 is formed by a plurality of (two in the figure) locking portions 36 at different distances from the opening end 36'.
a, 36b. Note that 37 is a handle.

As shown in FIG. 3B, the draining basket 40 is formed of, for example, a mesh-like trunk body 41 and a bottom 42, and a band 43 is wound around the upper opening of the trunk body 41 by brazing. . This band 43 is provided with protrusions 44 in a number corresponding to the notches 36 (four in this embodiment) that fit into the locking parts 36a and 36b.

In addition, in the above-mentioned structure, it is not necessary to necessarily provide the notch 36 in the body body 31 of the basket receiver 30, and the belt 4 wound around the body body 41 of the draining basket 40.
A plurality of holes may be provided in which the projections 44 of No. 3 are fitted. In that case, it goes without saying that the positions of the holes are different in the height direction of the trunk body 31 of the basket holder 30.

Further, instead of the mesh, a large number of small holes may be provided in the body body 41 and the bottom 42 of the draining basket 40.

Next, the operation of the sink basket 20 of the present invention will be explained.

First, insert the protruding part 44 of the draining basket 40 along the notch 36 of the basket holder 30, and then insert the protruding part 44 of the draining basket 40 into the appropriate locking part 36a.
Or, it is locked at 36b to form the sink basket 20. This sink basket 20 is inserted from the open end of the drainage section 3, and the sink basket 20 is arranged so that the flange 32 is placed on the annular seat 8' connected to the annular member 8.

In this case, the total length of the sink basket 20 (hereinafter referred to as total length l) and the outer diameter of its flange (hereinafter referred to as outer diameter d)
) is slightly smaller than the depth H and opening diameter D of the drainage section 3, the sink basket 20 can be inserted into the drainage section 3 as is.

On the other hand, when the outer diameter d of the flange 32 is larger than the opening diameter D, the outer peripheral edge of the flange 32 is inserted into the groove 33 or 3.
Cut along 4 with a tool such as a cutter,
The outer diameter may be reduced to match the opening diameter D.
In this case, since the groove is provided with a hole 33A, it can be easily cut.

Further, for example, the protrusion 44 may be attached to the locking portion 36a at the beginning.
When the basket holder 30 and the draining basket 40 are connected by fitting together, if the total length l is greater than the depth H, the locking portion 36 located above the locking portion 36a
By connecting the basket holder 30 and the draining basket 40 using b, and making the total length l of the sink basket 20 smaller than the predetermined depth H, it becomes possible to insert it into the drain part 3. .

As detailed above, according to the present invention, the outer peripheral edge of the flange of the basket holder can be cut out, and the position at which the draining basket is attached to the basket holder can be changed in the height direction. , one type of sink basket can be used for many types of drainage sections with different opening diameters and depths.

As a result, the general consumer who is the user is freed from the trouble of having to perform troublesome preparation work such as measuring the dimensions of the drainage part before purchasing a sink basket.

Furthermore, since it becomes possible for manufacturers of sink baskets to define two or three types of standard size baskets and to manufacture them in large quantities, it is possible to substantially reduce the production cost of the baskets.
