DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lid for inserting a drain pipe used to close a hole formed so as to allow a drain pipe to pass through a bottom plate of a cabinet such as a sink or a sink.

[0002]

2. Description of the Related Art As is well known, a drain pipe for connecting a sink attached to a cabinet such as a sink or a wash basin to a drain pipe is detachably attached to a hole formed in a bottom plate of the cabinet. It is inserted through the lid to be attached.

When the drainage pipe is a flexible drainage pipe that can be freely bent, the insertion hole of the drainage pipe formed in the lid is made to match the diameter of the flexible drainage pipe and is formed at the center of the lid body. Even if it is opened, the positional error between the sink drain of the above cabinet and the drain can be absorbed.

[0004] However, when the drain pipe is formed of a hard straight pipe, a gap between the sink drain port and the sewer pipe often causes a positional error. A hole for inserting the drainage pipe is opened, and an insertion hole for inserting the drainage pipe in a lid used to close the hole is opened corresponding to the diameter of the drainage pipe. It is common to insert a drain pipe in the pipe.

Conventionally, a disc-shaped lid 1 or lid 5 as shown in FIGS. 7 and 8 or FIGS. 9 and 10 is used as a member through which such a hard straight pipe is inserted. .

As shown in FIGS. 7 and 8, the conventional lid 1 is made of a disc-shaped synthetic resin in which the main body 2 is formed to have a diameter larger than the diameter of a hole formed in the bottom plate. At the center O ₁ and at a position O ₂ eccentric from the center O ₁ , circular and thin cutting guide grooves 3A, 3B, 3C for cutting corresponding to different drainage pipe diameters are formed. because it is formed concentrically, after adjusting the standing設軸heart drain pipe to the center O ₁ or O ₂ either, so as to correspond to the diameter of the drain pipe for inserting the cutting guide groove 3A, 3B, 3C
After cutting one of the above with a cutter and inserting the drain pipe,
The lid 1 is used to fix the lid 1 to the peripheral edge of the hole of the bottom plate with a double-sided fixing tape 4 disposed on the back side of the main body 2.

However, in the conventional cover plate 1 configured as described above, at the time of construction, after selecting either the center O ₁ or O ₂ in accordance with the vertical axis of the drainage pipe, either of the _two is selected. Circular cutting guide groove 3 at the center O ₁ or O ₂
Since any one of A, 3B, and 3C must be cut in accordance with the diameter of the drain pipe, such an operation is very complicated, and the circular cutting guide grooves 3A, 3B, and 3C are standardized and formed. Therefore, when inserting a drain pipe having a diameter that does not match the circular cutting guide grooves 3A, 3B, and 3C, the circular cutting guide grooves 3A, 3 which are slightly larger than the circular cutting guide grooves 3A, 3B, and 3C are inserted.
B and 3C had to be cut, and there was a problem that a gap was opened and the sealing property was easily impaired.

On the other hand, as shown in FIGS. 9 and 10, the lid 5 according to another conventional example is formed of a disc-shaped synthetic resin having a diameter larger than the diameter of the drain pipe. An oval hole 7 is formed in the main body 6, a drain pipe insertion member 8 formed in an oval shape with synthetic resin is fitted into the hole 7, and a position O eccentric from the center O _{3 of the} main body 6. ₄ , a drain pipe insertion hole 9 is opened, and the main body 6 is rotated in the circumferential direction. Although not shown, the main body 6 is set at a position capable of absorbing a positional error between the sink drain port of the cabinet and the sewer pipe. The cover 5 is configured to be fixed to the bottom plate with a fixing double-sided tape (not shown) disposed on the back surface side of the cover 6.

However, in the above-mentioned conventional lid body 5 formed of the two members of the main body 6 and the drain pipe insertion member 8, the drain pipe insertion member 8 is adapted to the diameter of the drain pipe at the time of construction. Since the drain pipe insertion member 8 is relatively thick and does not have a guide groove for cutting, the cutting operation is very complicated, and The cover 5 is composed of the main body 6 and the drain pipe insertion member 8.
Since it is formed of a member, there is a problem that the number of parts increases and the cost increases.

The present invention has been made in view of the above situation, and an object of the present invention is to provide a drain pipe made of hard straight pipes having different diameters in accordance with the diameter. It can be easily inserted into the lid,
An object of the present invention is to provide a low-cost lid that can easily absorb a positional error between a sink drain and a sewer pipe.

[0011]

In order to achieve the above object, in a drain pipe insertion cover according to the present invention, a drain pipe insertion hole 19 formed in a bottom plate 18 of a cabinet is closed. Body 11 for inserting a drain pipe, and a plurality of leg pieces having a substantially rectangular shape on the lower surface of the body 11 and bulging at predetermined intervals along the circumferential direction. 13
And a drain pipe insertion part 12 made of a soft resin integrally formed with the lid body 11.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to an embodiment shown in the accompanying drawings.

As shown in FIGS. 1 to 3, a lid 10 for inserting a drain pipe according to this embodiment is formed integrally with a lid body 11 made of hard resin. And a drainage pipe insertion portion 12 made of a soft resin.

The cover body 11 has a hole 19 formed in a cabinet bottom plate into which the cover body 11 is removably fitted.
It is formed of a disc body having a larger diameter than that of the disc body (see FIGS. 5 and 6), and a plurality of leg pieces 13 are formed on the lower surface thereof at predetermined intervals along the circumferential direction. In addition, an elongated hole 14 for holding the insertion portion 12 is provided.

As shown in FIGS. 5 and 6, a locking piece 15 formed in an approximately T-shape is protruded from the peripheral wall portion 14a forming the elongated hole 14, and is formed of a hard resin. After the lid main body 11 is molded, a soft resin is poured into the elongated hole 14 and cured, whereby the insertion portion 12 is integrally formed in a state in which the insertion portion 12 is in close contact with the peripheral portion of the elongated hole 14.

The insertion portion 12 thus formed is
Together are formed in the oval shape is a similar figure with the long hole 14, the axis O _B is formed eccentrically from the position O _A which is the center of the lid body 11, also, the planar portion the 12a, as shown in FIGS. 1 and 2, a plurality of slit 16 toward the outer peripheral direction from the axis O _a of the lid body 11 is formed radially.

Also, on the back side of the insertion portion 12, FIG.
As shown in the figure, a thin-walled cutting guide groove 17 is formed in a recess along the extending direction of each slit 16 .

On the other hand, as shown in FIGS. 4 to 6, the leg piece 13 has an outer surface formed in a substantially rectangular shape.

By configuring the leg pieces 13 in this manner, for example, when the thickness of the bottom plate 18 of the cabinet is thinner than the distance from the lower surface of the lid body 11 to the protruding end 13a of the leg pieces 13, As shown in FIG. 5, the bottom plate 18
The peripheral edge of the hole 19 is fitted and locked between the lower surface of the lid body 11 and the protruding end 13 a of each leg 13.

The thickness of the bottom plate 18 of the cabinet is such that the projecting end 1
If it is thicker than the distance up to 3a, as shown in FIG.
The protruding end portion 13a of each leg piece 13 is
Is elastically contacted and locked to the peripheral edge portion.

Therefore, in the lid 10 according to this embodiment, due to the configuration and operation of each of the legs 13, even if the bottom plate thickness of the cabinet is different, it can be easily fitted and locked. Therefore, compared with the case of fastening with double-sided adhesive tape, the effect that construction is very easy is obtained.

Since the lid 10 according to this embodiment is configured as described above, a drain pipe made of a hard straight pipe is inserted into the lid 10 and the lid 10 is connected to the bottom plate 1.
In the case of mounting in the hole 19 of FIG. 8, first, each leg 13 of the lid 10 is inserted into the hole 19 of the bottom plate 18, and the lid body 11 is pressed and fitted from above.

At this time, when the lid body 11 is rotated in the circumferential direction and the center of the slit 16 of the insertion portion 12 is set up on the drain pipe connecting the sink drain port of the cabinet and the drain pipe. Set so that it is coaxial with the axis of.

The vertical axis of the drain pipe connecting the sink drain port of the cabinet and the sewer pipe is connected to the insertion portion 12.
In the case where it is shifted from the center of the slit 16, the lid 10 was turned upside down before being mounted on the hole 19, and cut along the cutting guide groove 17 to cut the slit 16 long. Thereafter, the drain pipe can be inserted into a position corresponding to the axis when the drain pipe is erected by turning over and inserting the drain pipe into the slit 16. At this time, since each tongue piece 20 of the insertion portion 12 cut and formed elastically contacts the outer surface of the drain pipe, the bottom of the cabinet can be effectively hidden.

In the above embodiment, the case where a plurality of leg pieces 13 are provided at predetermined intervals on the lower surface of the lid main body 11 has been described as an example. The present invention is not limited to this. The double-sided adhesive tape is provided on the back surface of the lid body 11 by eliminating the leg pieces 13 and the lid body 11 is fixed to the bottom plate of the cabinet via the double-sided adhesive tape. Of course, it may be constituted.

[0026]

As described above, in the lid according to the present invention, since the lid body made of hard resin and the insertion portion of the drainage pipe made of soft resin are integrally formed, productivity is improved and cost is improved. The lower part of the lid body is formed, and a plurality of legs having a substantially rectangular shape are formed at predetermined intervals along the circumferential direction on the lower surface of the lid body. Is thinner than the distance from the lower surface of the lid body to the protruding end of each leg, the peripheral edge of the hole of the bottom plate is formed between the lower surface of the lid main body and the protruding end of each leg. If the projection is thicker than the distance from the lower surface of the lid body to the protruding end of each leg, the protruding end resiliently contacts the peripheral edge of the hole of the bottom plate. Because it can be stopped, it can greatly simplify the construction compared to the conventional case of fastening with double-sided adhesive tape. Can. Further, in the present invention, an oval insertion portion made of a soft resin is formed eccentrically, and a cutting guide groove formed in the insertion portion of the drain pipe corresponding to the diameter of the drain pipe is formed. Since the drainage pipe is configured to be inserted into the lid by cutting, even if the drainage pipe is formed of a hard straight pipe having a different diameter, the position error between the drainage port and the sewer pipe can be easily and accurately determined. And the lid can be attached to the bottom of the capinet.
Any existing diameter can be matched to the diameter of the rigid straight pipe, and moreover, there is no need to prepare multiple types of lids corresponding to the diameter of the rigid straight pipe, so further cost reduction can be achieved. Further, the cutting guide groove is cut in accordance with the position and diameter of the hard straight pipe to be inserted, and each tongue piece is in elastic contact with the outer surface of the drain pipe, so that it is opened on the bottom plate. It has a number of excellent effects, such as almost completely concealing the hole.
