Description

The present invention relates to a chrysanthemum crack lid used for a sink of a sink.

  The present applicant has proposed the chrysanthemum crack lids fitted into the upper part of the drain outlet of the sink and used as shown in FIGS. 6 and 7 (see Japanese Patent Application No. 2002-204746 and drawings). 6 and 7, the chrysanthemum crack lid 70 is made of rubber and has an annular frame part 72 having an inner peripheral surface i forming an upper opening 71 having a circular shape in plan view, and a chrysanthemum cracked bottom part 73 having a circular shape in plan view. More specifically, the bottom 73 is composed of a plurality of chrysanthemum tongues 74 provided continuously from the inner peripheral surface i of the annular frame 72.

  In addition, the ring frame 72 has three ring portions adjacent to each other via, for example, two annular grooves 75 and 76 formed concentrically and downwardly so as to be cut to a size suitable for the size of the drainage port. 77, 78, 79 are provided. The ring portion 77 is an innermost ring portion having a lower surface portion 79 that is connected to the chrysanthemum-shaped bottom portion 73, and the remaining two ring portions 78 and 79 are located outside the ring portion 77. It is a ring part which can be cut off through the cut parts a and b, respectively.

  By the way, the cut portion a is formed between the outer annular groove 75 and the annular groove 80 formed on the upper surface 72a of the annular frame portion 72, and the cut portion b is formed on the inner annular groove 76. , And the annular groove 81 formed on the upper surface 72a of the annular frame portion 72. However, since the cut portions a and b are formed thick in the vertical direction, the ring portions 79 and 78 are peeled off by hand. Sometimes it is difficult to cut, for example, even if the cut portion a is cut off, the rubber that has not been cut off remains on the outer peripheral surface of the inner ring portion 78. Therefore, tools such as scissors and a cutter knife are required.

  The present invention has been made in consideration of the above-mentioned matters, and an object of the present invention is to provide a chrysanthemum crack lid that can be easily cut out by hand without using a tool such as scissors or a cutter knife. is there.

In order to achieve the above object, the chrysanthemum cracking lid of the present invention has an annular frame part and a chrysanthemum cracked bottom part, and the chrysanthemum cracking lid provided at the upper part of the drain outlet of the sink through the annular frame part. The annular frame portion has a substantially comb-shaped longitudinal section, and has a plurality of ring portions adjacent to each other via an annular groove formed concentrically and downwardly, and at the bottom of each annular groove. It has a continuous cut-out portion, and the bottom portion has a tapered shape.

In this invention, a plurality of ring portions of the annular frame portion are adjacent to each other via an annular groove formed concentrically and downwardly, and a bottom portion of each annular groove is tapered to form a cutout portion continuous to the bottom portion. Since it is formed, it is possible to obtain a cut portion that is thinner in the vertical direction than the conventional cut portion, and thus the cut portion can be easily cut by hand without using a tool such as scissors or a cutter knife. Can do.

Embodiments of the present invention will be described below with reference to the drawings. The present invention is not limited thereby.

1 to 5 show an embodiment of the present invention. FIG. 3 shows a chrysanthemum lid, with a top view on the right side facing the front and a bottom view on the left side facing the front.
1 to 5, reference numeral 1 denotes a chrysanthemum crack lid that is used by being fitted into the upper part 2 a of the sink drain port 2, and a garbage receiving basket B is installed immediately below the chrysanthemum crack lid of the sink drain port 2. .

  The chrysanthemum crack cover 1 is mainly composed of an annular frame part 3 having an inner peripheral surface i that forms an upper opening 3a that is circular in plan view, and a chrysanthemum crack shaped bottom part 4 that is circular in plan view. The bottom part 4 is composed of a plurality of chrysanthemum crack tongues 5 provided continuously from the inner peripheral surface i of the annular frame part 3. The said annular frame part 3 has the annular grooves 28 and 29 formed in the inner side and the outer side of the upper surface.

  The inner peripheral surface i of the annular frame portion 3 is not a vertical surface but a tapered surface that is inclined so as to have a smaller diameter as it goes downward. The bottom portion 4 has a round hole 7 in the center portion, and a plurality of drainage long holes 8 communicating with the dust receiving basket B along the circumferential direction on the inner peripheral surface i side away from the round hole 7. Have in state. The drainage long holes 8 are longer in the radial direction than in the circumferential direction.

  9 is a resin lid that is detachably installed on the bottom 4 of the chrysanthemum crack lid 1 so as to cover the upper opening 3a. The lid 9 is composed of a lid top plate 11 having a circular shape in plan view, and an annular drooping plate 12 connected downward from the outer peripheral edge 11 a of the lid top plate 11. When the lid 9 is installed on the bottom portion 4 of the chrysanthemum crack lid 1, the outer peripheral surface of the hanging plate 12 becomes smaller in diameter as it goes down so as to be fitted into the inner peripheral surface i of the annular frame portion 3 so as to be sealable. It is formed in the taper surface which inclines so that it may become. Therefore, it is possible to prevent drainage from leaking into the drainage long hole 8 and the round hole 7 provided in the bottom portion 4, and water, hot water, or mixed water can be stored in the sink A of the sink.

  The annular frame portion 3 has a substantially comb-shaped longitudinal section, and has three ring portions 22, 23, 24 adjacent to each other via, for example, two annular grooves 20, 21 formed concentrically downward. . With these three ring portions 22, 23, 24, it is possible to cope with the case where there are three types of diameters of the drainage port 2 of the sink (for example, Φ150mm, Φ142mm, Φ134mm). In addition, in this invention, it can apply also when the annular frame part 3 has four or more ring parts. The annular grooves 20 and 21 are formed several tens of times deeper than the depth of the annular grooves 28 and 29 formed on the upper surface of the annular frame 3. The annular groove 20 and the annular groove 21 have the same vertical cross section.

  A cut-out portion M that is continuous with the bottom 31 of the annular groove 21 is formed between the annular groove 21 and the annular groove 28 formed inside the upper surface of the annular frame portion 3. Further, a cut-out portion N that continues to the bottom 30 of the annular groove 20 is formed between the annular groove 20 and the annular groove 29 formed on the outer surface of the annular frame 3.

  Of the three ring portions 22, 23, 24, the innermost ring portion 24 has a lower surface portion 25 that is connected to the chrysanthemum-shaped bottom portion 4. When the diameter of the sink outlet 2 is Φ150 mm, the chrysanthemum cover 1 can be fitted into the upper part 2a of the sink outlet 2 without cutting out the cut portions M and N. When the diameter of the sink outlet 2 is Φ142 mm, the outer diameter of the chrysanthemum crack cover 1 is adapted to the diameter of the sink outlet 2 by cutting out the cutout portion N, and the annular frame portion 3 is connected to the ring portion 23. , 24 chrysanthemum crack lids 1 can be fitted into the upper part 2a of the drainage outlet 2 of the sink. Furthermore, when the diameter of the drain port 2 of the sink is Φ134 mm, first, the cut-out portion N is cut out, and then the cut-out portion N is cut out sequentially or with the ring portion 22 attached to the ring portion 23. Only the portion N is cut out so that the outer diameter of the chrysanthemum cracking lid 1 is adapted to the diameter of the drainage outlet 2 and the upper part of the drainage outlet 2 where the annular frame part 3 flows through the chrysanthemum cracking lid 1 having only the ring part 24 2a.

  The characteristic configuration of the present invention will be described below.

  As described above, the annular groove 20 and the annular groove 21 have the same vertical cross section. For example, the bottom portion 30 of the annular groove 20 has a tapered shape that reaches the cut portion N while inclining from the outside to the inside. That is, the annular groove 20 includes a downward opening portion 32 formed in a substantially rectangular longitudinal section and the bottom portion 30 formed in a substantially right-angled triangular section in connection therewith. That is, the bottom portion 30 has a tapered surface 30a that reaches the cut-out portion N while inclining inward from the outside toward the top. Therefore, the cut portion N can be formed thin in the vertical direction (vertical direction).

  The bottom portion 31 of the annular groove 21 has a tapered shape that reaches the cutout portion M while inclining from the outside to the inside. That is, the annular groove 21 is composed of a downward opening portion 33 formed in a substantially rectangular longitudinal section and the bottom portion 31 formed in a substantially right-angled triangular section in connection therewith. That is, the bottom portion 31 has a tapered surface 31a that reaches the cut-out portion M while inclining inward from the outside toward the inside. Therefore, the cut portion M can be formed thin in the vertical direction (vertical direction).

  Therefore, the cut portions M and N can be easily cut by hand without using a tool such as scissors or a cutter knife.

  Each of the ring portions 22 and 23 to be cut off has inverted V-shaped cutouts 33 and 34 on the peripheral surface, which serve as a guide for starting cutting. The inverted V-shaped notches 33 and 34 are provided at positions where they do not overlap. This is because if the inverted V-shaped notches 33 and 34 are provided at overlapping positions, only the ring portion 22 for one round is intended to be peeled off, but the two rounds of the ring portions 22 and 23 are cut at a time. Because there is a fear.

  The taper surface of the bottom 30 reaching the cut-out portion N may be inclined upward from the inside toward the top, and the taper surface of the bottom 31 reaching the cut-out portion M is directed from the inside to the outside toward the top. It may be inclined.
