Description

[Technical Field]

[0001] The present invention relates to a net holder for attaching a net that catches garbage in drainage, and a cover member equipped with the net holder. [Background technology]

[0002] As the cover member, there is known one that is placed on the drain outlet of a sink and to which a net for collecting garbage in the drain can be attached (see Patent Document 1).

[0003] The cover member described in Patent Document 1 includes a cover body that covers the drain outlet, and a net holder that is placed below the cover body. The net holder is ring-shaped and has protrusions for holding the net that catches garbage, and is placed on a step inside the drain outlet. The net is a bag that allows drainage to pass through but has a mesh-like catch section that can catch hair, kitchen waste, etc., and is held in place by hanging the opening from the protrusion on the net holder.

[0004] In the above Patent Document 1, the net on which the dust has been collected can be removed from the net holder and discarded, making cleaning easy. Furthermore, Patent Document 1 describes a modified example in which the cover body and the net holder are integrated. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Application Publication No. 2024-100527 Summary of the Invention [Problem to be solved by the invention]

[0006] With the cover member described in Patent Document 1, when discarding the net, it is necessary to first remove the cover body from the drain outlet, and then remove the net holder from the drain outlet. On the other hand, in the modified example in which the cover body and the net holder are integrated, the cover body and the net holder can be removed from the drain outlet at the same time, which is easy to work with.

[0007] Here, the cover member is visible to the user, so design is required. However, the modified example in which the cover body and the net holder are integrated is difficult to form from metal material due to its complex shape. A typical cover body is made by processing a single metal plate by press molding, but this molding process is particularly difficult. Furthermore, if a user already owns a cover body, purchasing a new cover member that integrates the cover body and net holder would result in the existing cover body going to waste.In particular, in recent years, cover bodies with designs that match the tank body are often attached to the tank body, and there is a demand to use such cover bodies.

[0008] In view of the above-mentioned circumstances, the present invention aims to provide a cover member that solves one or more of the following problems: providing a cover member having a cover body made of metal material; providing a cover member that is easy to mold; and providing a cover member that can reuse an existing cover body. [Means for solving the problem]

[0009] The cover member according to one aspect of the present invention includes a cover body having an upper surface portion that covers a drain outlet and a side surface portion that extends downward from the upper surface portion; a net holder having a protrusion for holding a net for collecting dust, The net holder has a detachable locking portion on a side surface of the cover body, At least one of the side surface portion and the locking portion is elastically deformable. [Effects of the Invention]

[0010] This configuration can solve one or more of the following problems: providing a cover member having a cover body made of metal material; providing a cover member that is easy to mold; and providing a cover member that can reuse an existing cover body. [Brief explanation of the drawings]

[0028] In the ninth aspect, by using a metal for the net holder, it is possible to improve the design and cleaning properties while providing elasticity to the member.

[0029] Below, embodiments of the cover member according to the present invention will be described with reference to the drawings. The embodiments described below are comprehensive or specific examples, and the numerical values, shapes, materials, components and their arrangement and position, connection configuration, procedures, etc. are merely examples and do not limit the present invention. Furthermore, among the configurations in the following embodiments, configurations not described in independent claims can be modified as needed. Note that FIG. 5 is a top view showing the state in which the net holder 60 is attached to the cover body 50, with the top surface 51 of the cover body 50 cut away.

[0030] (First embodiment) As shown in Figures 1 and 2, the cover member 40 in the first embodiment is arranged at the drain outlet 21 of the tank body 10, which is the sink of the sink, and captures the food waste in the drain outlet 21 with the net 30 and covers the food waste to improve the design.

[0031] [Tank body] The tank body 10 is made of a metal plate material and is a box body with an open top and a drainage port member 20 attached to the bottom. The drain outlet member 20 is a generally elbow-shaped member that forms a drain outlet 21 on the bottom surface of the tank body 10 when attached to the tank body 10, and has a cylindrical portion 22 that forms a drainage flow path inside, a flange portion 24 formed at the upper end of the cylindrical portion 22, and an outlet 26 formed on the side surface of the cylindrical portion 22. A male thread that screws into a nut member 25 is formed on the side surface of the cylindrical portion 22, and the tank body 10 is clamped and fixed by the flange portion 24 and the nut member 25. Furthermore, a step 23 that protrudes inward is formed inside the cylindrical portion 22, approximately 20 mm below the upper end of the drain outlet 21. A drain pipe is connected to the outlet 26 and continues to a pipe rising from under the floor.

[0032] [net] The net 30 is an elastic mesh woven from polyethylene terephthalate threads, and has an opening 31 through which wastewater and kitchen waste flow in, and a trapping section 32 that traps the kitchen waste. When wastewater flows in through the opening 31, the capture section 32 allows the wastewater to pass through while capturing only the kitchen waste contained in the wastewater.

[0033] The form of the net 30 is not limited, and it can be a nonwoven fabric, a bag with water-passing holes, etc. The material of the net 30 is not particularly limited, and it can be made of resin, metal, paper, or other materials.

[0034] [Cover material] As shown in FIGS. 3 to 6, the cover member 40 is made of a metal material such as stainless steel, and includes a cover body 50 and a net holder 60 that holds the net 30.

[0035] The cover body 50 is a screen member made by press-molding a metal plate, and has an upper surface portion 51 that covers the drain outlet 21 and a side surface portion 53 that extends downward from the upper surface portion 51. The upper surface portion 51 has a circular shape in plan view with approximately the same diameter as the drain outlet 21, and has an inlet portion 52 into which the drainage water flows. The side surface portion 53 is cylindrical and extends downward from the outer edge of the upper surface portion 51. The side surface portion 53 tapers inward as it extends downward, with the diameter decreasing, and the upper end having the largest diameter.

[0036] The net holder 60 is generally ring-shaped and formed by bending a metal wire and welding the ends. It is elastically deformable when stress is applied. The net holder has a locking portion 61 that locks onto the cover body 50 and a protrusion 62 that holds the net 30. The locking portions 61 and the protrusion 62 are radially projected outward from the net holder 60, and the locking portions 61 and the protrusion 62 are alternately formed at eight locations via vertically extending pillar portions 63. When the net holder 60 is attached to the cover body 50, the locking portions 61 are located above the protrusions 62. In FIG. 4 , an imaginary circle C1 indicated by a two-dot chain line connects the outer edges of the locking portions 61 and the protrusions 62, and an imaginary circle C2 indicated by a two-dot chain line connects the outer edges of the pillar portions 63. The locking portion 61 is generally rectangular in plan view and extends so as to slope obliquely upward as it extends toward the outer edge. The protrusion 62 is generally triangular in plan view, with its apex projecting in a generally horizontal direction. The imaginary circle C1 has a diameter that is approximately the same as or slightly larger than the inner diameter at the upper end of the side surface portion 53 of the cover body 50, and is larger than the inner diameter at the lower end of the side surface portion 53 and the inner diameter of the step portion 23. The imaginary circle C2 is larger than the inner diameter of the inlet portion 52 of the cover body 50 and the opening 31 of the net 30 in an unstressed state.

[0037] [Attaching and detaching the net holder] When attaching the net holder 60 to the cover body 50, first, stress is applied inward to the net holder 60 to deform it in the direction of reducing its diameter. In this state, the locking portion 61 of the net holder 60 is positioned inside the side portion 53, thereby completing the attachment to the cover body 50. When the net holder 60 is disposed inside the cover body 50 and the inward stress is released, the net holder 60 expands in diameter due to an outward restoring force, and the locking portion 61 abuts against the inside of the side surface portion 53. At this time, the imaginary circle C1 formed by the outer edge of the locking portion 61 in the expanded diameter state (when no stress is applied) is larger than the inner diameter of the side surface portion 53 of the cover body 50 in a plan view. Therefore, as shown in FIGS. 5 and 6 , the locking portion 61 presses the side surface portion 53 radially outward. Furthermore, because the side surface portion 53 tapers inward as it extends downward, thereby reducing its diameter, the locking portion 61 is guided by the inner surface of the side surface portion 60 and positioned above the lower end of the side surface portion 60 (near the upper end of the side surface portion 60). Therefore, even if downward stress is applied to the net holder 60, the locking portion 61 is locked to the side surface portion 53, preventing the net holder 60 from coming off. On the other hand, when removing the net holder 60 from the cover body 50, the diameter is reduced by applying inward stress to the net holder 60 again. At this time, by reducing the diameter of the locking portion 61 below the inner diameter of the lower end of the side portion 53 of the cover body 50, the net holder 60 can be removed from the cover body 50.

[0038] [Installing the net] When attaching the net 30 to the net holder 60, first, the openings 31 of the net 30 are widened to be larger than the protrusions 62. Next, the net 30 is placed over the protrusions 62 so that the protrusions 62 are positioned inside the net 30, and the net 30 is hung from the protrusions 62. At this time, the diameter of the net 30 is reduced by its own restoring force, so that the protrusions 62 come into contact with the inside of the net 30, preventing it from coming off the protrusions 62. Furthermore, when the cover member 40 is attached to the inside of the drain outlet 21 with the net 30 attached, the protrusions 62 are placed on the step 23 via the net 30. At this time, the net 30 is sandwiched between the protrusions 62 and the step 23, further preventing the net 30 from coming off the protrusions 62. Furthermore, since the pillar portion 63 is formed at the inner peripheral end of the protrusion portion 62, the diameter of the opening 31 does not become smaller than the imaginary circle C2. Therefore, all of the wastewater that flows in from the inlet portion 52 of the cover body 50 flows into the opening 31 and passes through the capture portion 32.

[0039] [Action and effect] As described above, in the cover member 40 of this embodiment, the cover body 50 is made of a metal material, which makes it possible to improve the design. Furthermore, since the net holder 60 is attached to the cover body 50, the cover body 50 and the net holder 60 can be removed from the drain outlet 21 at the same time. On the other hand, because the net holder 60 is made of wire, it can be easily attached and detached from the cover body 50 by elastic deformation. Therefore, the net holder 60 can be easily removed from the cover body 50 and cleaned. Also, the net holder 60 can be attached to an existing cover body for use. In addition, when the net holder 60 of the cover member 40 is placed on the step portion 23, the net 30 is sandwiched between the net holder 60 and the step portion 23, thereby preventing the net 30 from coming off the protrusion 62. Furthermore, since the net holder 60 is formed by bending a wire rod, no mold is required, making it possible to reduce initial investment. Furthermore, the engaging portion 61 is extended so as to slope diagonally upward as it progresses toward the outer edge, so that even if the upper surface of the cover body 50 to which it is attached is recessed to form a drainage gradient, the engaging portion 61 is configured not to interfere.

[0040] Second Embodiment The configuration of the cover member 40a according to the second embodiment will be described. In the following embodiments, the same members and configurations as those in the first embodiment will be denoted by the same reference numerals as those in the first embodiment, and the description thereof will be omitted.

[0041] 7, in the cover member 40a according to the second embodiment, a plurality of notches 54 are formed in the side surface portion 53a of the cover main body 50a from the lower end toward the upper side, and the side surface portion 53a can be deformed in a radially expanding direction. As in the first embodiment, the side surface portion 53a is tapered inward as it extends downward, thereby decreasing in diameter, with the upper end being the largest diameter.

[0042] In this embodiment, when attaching the net holder 60 to the cover body 50a, the side surface portions 53a are spread apart by the net holder 60. In this state, the attachment to the cover body 50a is completed by placing the locking portions 61 of the net holder 60 inside the side surface portions 53a. When the net holder 60 is placed inside the cover body 50a, the stress that was spreading the side surface portions 53a is released, causing the side surface portions 53a to contract in diameter due to an inward restoring force, and the locking portions 61 come into contact with the inside of the side surface portions 53a. 4 is larger than the inner diameter of the side surface portion 53 of the cover body 50 in a plan view, the locking portion 61 presses the side surface portion 53a radially outward. Furthermore, the side surface portion 53a tapers inward as it extends downward, thereby reducing its diameter, so the locking portion 61 is guided by the inner surface of the side surface portion 60 and positioned above the lower end of the side surface portion 60 (near the upper end of the side surface portion 60). Therefore, even if downward stress is applied to the net holder 60, the locking portion 61 is locked to the side surface portion 53a, preventing the net holder 60 from coming off.

[0043] (Third embodiment) The configuration of the cover member 40b according to the third embodiment will be described below. In the third embodiment, the configuration of the cover body 50 is the same as that in the first embodiment.

[0044] As shown in Figures 8 and 9, in the cover member 40b of the third embodiment, the net holder 60a is approximately ring-shaped and made of resin material, and has a locking portion 61a that locks onto the cover main body 50 and a protrusion portion 62a that holds the net 30. The locking portion 61a is a plate-like member that protrudes upward and is elastically deformable inward. The protrusions 62 are generally triangular in plan view and are formed radially so that the vertices protrude generally horizontally toward the outside in the radial direction. The imaginary circle C3 shown by the dotted line in Figure 8 is an imaginary circle connecting the outer edges of the engaging portion 61a, and has a diameter that is approximately the same as or slightly larger than the inner diameter at the upper end of the side portion 53 of the cover body 50, and is larger than the inner diameter at the lower end of the side portion 53, the inner diameter of the step portion 23, the inlet portion 52 of the cover body 50, and the inner diameter of the opening 31 of the net 30 when no stress is applied.

[0045] In this embodiment, when attaching the net holder 60a to the cover body 50, the net holder 60a is pressed against the cover body 50, deforming the locking portions 61a inward. In this state, the locking portions 61a of the net holder 60a are positioned inside the side surface portions 53, thereby completing the attachment to the cover body 50. When the net holder 60a is positioned inside the cover body 50, the stress that had been deforming the locking portions 61a is released, and the locking portions 61a expand in diameter due to an outward restoring force, and the locking portions 61a come into contact with the inside of the side surface portions 53. At this time, an imaginary circle C3 formed by the outer edges of the locking portions 61a in the expanded diameter state (when no stress is applied) is larger than the inner diameter of the side surface portions 53 of the cover body 50 in a plan view, and therefore the locking portions 61a press the side surface portions 53 radially outward. Moreover, since the side surface portion 53 tapers inward as it extends downward, the locking portion 61a is guided by the inner surface of the side surface portion 60 and positioned above the lower end of the side surface portion 60 (near the upper end of the side surface portion 60). Therefore, even if downward stress is applied to the net holder 60a, the locking portion 61a is locked to the side surface portion 53, preventing the net holder 60a from coming off.

[0046] (Fourth embodiment) The structure of the cover member 40c according to the fourth embodiment will be described below. In the fourth embodiment, the structure of the net holder 60 is the same as that in the first embodiment.

[0047] 10, in a cover member 40c according to the fourth embodiment, a side surface portion 53b of a cover body 50b is made of an elastic material such as rubber or soft resin, and is continuous with an upper surface portion 51 made of a metal material. As in the first embodiment, the side surface portion 53b is tapered inward as it extends downward, thereby decreasing in diameter, with the upper end having the largest diameter.

[0048] In this embodiment, when attaching the net holder 60 to the cover body 50b, as in the second embodiment, the net holder 60 pushes open the side portion 53b, and the engagement portion 61 of the net holder 60 is positioned inside the side portion 53b, thereby completing the attachment to the cover body 50a.

[0049] (Other variations, etc.) While the cover member of the present invention has been described above based on the embodiments, the present invention is not limited to the above embodiments. As long as it does not deviate from the spirit of the present invention, various modifications conceivable by those skilled in the art to the above embodiments and configurations constructed by combining components of different embodiments may also be included within the scope of one or more aspects. For example, as long as the net holder can be engaged with the cover body, only one of them needs to be elastically deformable. Therefore, in the second and fourth embodiments, the net holder may not be elastically deformable. In the above embodiment, the tank body 10 is a sink, but it may also be a bathtub, a bathtub pan, a washbowl, a washing machine pan, or the like. Moreover, the number and shape of the protrusions 62 and the locking portions 61 can be changed as desired to suit the tank body to which they are attached. Furthermore, the shape of the drain outlet is not limited to a circle, but may be a rectangle, ellipse, oval, or other shape. In this case, the cover body and the net holder may be changed to a rectangle, ellipse, oval, or other shape depending on the shape of the drain outlet. [Explanation of symbols]
