The present invention is provided in the drainage flow path such as washbasin or bathtub, a method for producing a hair catcher structure comprising a hair catcher over for trapping hair or dust.

  Conventionally, a hair catcher is placed on an object to be contacted which is a tank body (for example, a basin, a bathtub, a sink, etc.) or a member attached to the tank body (for example, a drain port member inserted into the drain port), A technique for collecting hair, dust, and the like that has flowed into a drain outlet is known. As the hair catcher, one formed of a resin is widely known. For example, an annular first ring portion supported by being placed on an object to be contacted, and an inner periphery of the first ring portion. An annular second ring portion that is positioned, and a collection portion (net portion) that is provided between both ring portions and collects hair, dust, and the like have been proposed (for example, Patent Documents). 1 etc.).

  By the way, in the above-described prior art, the hair catcher itself is formed to be relatively thick in order to ensure strength or the like, or a locally thick part (for example, a rib) is provided in a part of the hair catcher. Or However, when the hair catcher is formed thick, the depth of the hole along the thickness direction of the hair catcher becomes relatively large, and when cleaning the hair catcher, especially the hole is formed in the collecting part. There is a risk that the surface to be cleaned becomes very difficult. Furthermore, if a thick part is provided in a part of the hair catcher, the thick part may become an obstacle at the time of cleaning, and the cleaning property may be deteriorated.

  Further, with the movement of the hair catcher, a gap is formed between the outer periphery (first ring portion) of the hair catcher and the contacted object, and there is a possibility that hair, dust, etc. may flow down from the outer periphery of the hair catcher. However, in Patent Document 1, there is a method of providing a plurality of ribs projecting downward on the outer peripheral side of the back surface of the hair catcher, and preventing the hair catcher from shifting by contacting the contact object with the ribs. Proposed. However, in this method, as in the case where a thick portion is provided in a part of the hair catcher, the ribs may become an obstacle at the time of cleaning, and there is a possibility that the cleaning property is deteriorated.

The present invention has been made in view of the above circumstances, and the object thereof is to realize extremely good cleaning properties and to effectively suppress the occurrence of shifting movements, excellent hair, etc. it is to provide a method for producing a hair catcher structure comprising a hair catcher over which it is possible to obtain a trapping capacity of.

  In the following, each means suitable for solving the above-described object will be described in terms of items. In addition, the effect specific to the means to respond | corresponds as needed is added.

Means 1. An annular first ring portion;
An annular second ring portion disposed on the inner periphery of the first ring portion;
A hair catcher that is provided between the ring parts and includes a collection part in which a plurality of holes are formed, and is disposed at a drain outlet of the tank body, and
A method of manufacturing a hair catcher structure comprising a resin tubular member attached to the inner periphery of the second ring part,
Both the ring part and the collecting part are integrally formed and are thin,
At least the first ring part and the collecting part have a certain thickness, and
The virtual surface including at least the surface of the first ring portion and the surface of the collection portion is formed in a smooth surface shape without irregularities, and
The outer peripheral surface of the first ring portion is
A tapered upper annular surface that comes into contact with a contact object that is a member attached to the tank body or the tank body, and whose outer diameter decreases downward,
The upper annular surface is positioned below the upper annular surface and extends downward at an inclination angle larger than the inclination angle of the upper annular surface, and at least the upper annular surface is in contact with the contacted surface along its radial direction. A lower annular surface that can come into contact with the contacted object when it is displaced relative to the object;
With
The cylindrical member is
A cylindrical first cylindrical portion that protrudes toward the outer periphery and has an upper protrusion and a lower protrusion disposed apart in the axial direction;
A cylindrical second cylindrical portion having a locked portion capable of locking the lower protrusion on the inner periphery;
The upper protrusion has an outer diameter larger than an inner diameter of the second ring portion, and
The lower protrusion is configured to be elastically deformable along a radial direction,
The first tubular portion is inserted into the second ring portion, and the second ring portion is disposed between the upper protrusion and the lower protrusion. One cylindrical portion is inserted, the lower protrusion is locked to the locked portion, and the second ring portion is sandwiched between the upper protrusion and the upper end of the second cylindrical portion. Thus, the method for producing a hair catcher structure is characterized in that the hair catcher structure is obtained.

  “Thin” means that the thickness is, for example, 1 mm or less. Further, “having a constant thickness” includes not only the case where the thickness is strictly constant, but also the case where there is a slight difference (for example, 0.3 mm or less) in the thickness of each part.

  Furthermore, the second ring portion does not have to be a strict ring shape, and may be a discontinuous ring shape such as having a hole portion in part.

  In addition, the “inclination angle of the upper annular surface” refers to the contacted portion of the upper annular surface in the cross section including the central axis of the first ring portion in a state where the hair catcher is disposed at an ideal position. An acute angle among angles formed by a tangent of a part in contact with an object and a straight line orthogonal to the central axis. When the outline of the upper annular surface is linear in the cross section including the central axis, the “inclination angle of the upper annular surface” is the outline of the upper annular surface in the cross section including the central axis. An acute angle among the angles formed by (a straight line extending) and a straight line orthogonal to the central axis.

  Further, the "inclination angle of the lower annular surface" is a tangent of a portion that comes into contact with an object to be contacted when the hair catcher moves out of the lower inclined surface in the cross section including the central axis, An acute angle or a right angle among angles formed with a straight line orthogonal to the central axis. When the outline of the lower annular surface is linear in the cross section including the central axis, the “inclination angle of the lower annular surface” is the outline of the lower annular surface in the cross section including the central axis. An acute angle or a right angle among the angles formed by (a straight line obtained by extending) and a straight line orthogonal to the central axis.

  According to the means 1, at least the first ring part and the collecting part have a certain thickness, and the virtual surface including at least the surface of the first ring part and the surface of the collecting part is a smooth surface without unevenness. It is formed in a shape. That is, the front surface and the back surface of the first ring portion and the collection portion are in an uneven state except for the hole portion. Therefore, when the hair catcher is cleaned, the cloth or the brush is hardly caught, and a good cleaning property can be obtained.

  Furthermore, according to the means 1, the depth of the hole can be remarkably reduced because the collecting part and the like are thin. Therefore, when cleaning the hair catcher, by rubbing the front and back surfaces of the collection part with a cloth or brush, the surface on which the cloth or brush forms a hole in the collection part without being particularly conscious Will reach most of the depth direction. As a result, cleaning becomes very easy, and the cleanability can be further improved.

  In addition, according to the said means 1, the upper side annular surface which contacts a to-be-contacted object becomes a taper shape from which an outer diameter becomes small toward the downward direction. Therefore, due to the weight of the hair catcher, a force from the contacted object toward the central axis side of the hair catcher is applied to the upper annular surface. Therefore, the movement of displacement along the radial direction of the hair catcher can be effectively suppressed. Moreover, even if some deviation movement occurs in the hair catcher, the further deviation movement of the hair catcher can be suppressed by the lower annular surface coming into contact with the contacted object. In particular, in the above-described means 1, the inclination angle of the lower annular surface is larger than the inclination angle of the upper annular surface (that is, the lower annular surface stands up from the upper annular surface). The above movement can be regulated effectively. As a result, it can prevent more reliably that a clearance gap arises between a 1st ring part and a to-be-contacted object, and can further improve collection ability, such as hair and garbage.

Moreover, according to the said means 1, without using a special tool etc., a hair catcher can be easily attached with respect to a cylindrical member, and a hair catcher structure can be manufactured easily. Further, a large load is not applied to the hair catcher at the time of manufacture, and even when the hair catcher is thin, deformation and breakage can be more reliably prevented.

Furthermore, in manufacturing the hair catcher structure, for example, a method of integrating the hair catcher and the tubular member by insert molding is conceivable, but in this method, the manufacturing cost is relatively large. There is a fear. In this regard, according to the above means 1, since the hair catcher structure can be obtained by a simple method, the manufacturing cost can be effectively reduced.

Furthermore, according to the above means 1, the first projecting portion is extracted from the second tubular portion while elastically deforming the lower projecting portion and releasing the locking of the lower projecting portion with respect to the locked portion. It is relatively easy to separate the hair catcher and the tubular member. Therefore, after separating the hair catcher and the cylindrical member, both can be cleaned, and the cleaning performance can be improved.

Mean 2. The hair catcher method for manufacturing a hair catcher construction according to the means 1, wherein the lower side annular surface is one that extends along a direction perpendicular to the radial direction of the first ring portion.

  The phrase “extends along the direction perpendicular to the radial direction of the first ring portion” means that the hair catcher moves out of the lower inclined surface in the cross section including the central axis of the first ring portion. It means that the tangent of the part that comes into contact with the contacted object is orthogonal to a straight line (orthogonal straight line) orthogonal to the central axis. In addition, “perpendicular to the orthogonal straight line” means that the tangent of the portion of the lower inclined surface that comes into contact with the contacted object when the hair catcher is displaced is strictly orthogonal to the radial direction of the first ring portion. Not only when extending along the direction (the central axis direction of the first ring portion) but also when the tangent is slightly inclined with respect to the direction orthogonal to the radial direction [for example, including the central axis of the first ring portion In the cross section, the acute angle among the angles formed by the tangent and a straight line (orthogonal straight line) extending in a direction orthogonal to the central axis is 80 ° or more and less than 90 °.

  According to the said means 2, it is comprised so that a lower side annular surface may be extended in the direction substantially orthogonal to the moving direction (radial direction) when a hair catcher shifts | deviates. Therefore, further movement of the hair catcher can be more effectively regulated when the lower annular surface comes into contact with the contacted object along with the movement of the hair catcher. Thereby, it can suppress more reliably that a clearance gap arises between a 1st ring part and a to-be-contacted object, and can further improve collection ability, such as hair.

Means 3. The hair catcher, the entire circumference of the lower annular surface are separably constructed from the contacted object, that only pre SL upper annular surface is in contact with the contacted object, the contacted object method for producing a hair catcher construction according to the means 1 or 2, characterized in that that can be supported by.

  According to said means 3, the contact pressure of the 1st ring part with respect to a to-be-contacted part can be increased by making only an upper side annular surface contact a to-be-contacted part. Thereby, the adhesiveness of the 1st ring part with respect to a to-be-contacted part can be improved more, and the situation that hair etc. will flow from between the 1st ring part and a to-be-contacted part can be prevented more certainly. . As a result, the ability to collect hair and the like can be further enhanced.

Means 4. An annular first ring portion;

The cylindrical member is
A cylindrical first cylindrical portion that protrudes toward the outer periphery and has an upper protrusion and a lower protrusion disposed apart in the axial direction;
A cylindrical second cylindrical portion having a locked portion capable of locking the lower protrusion on the inner periphery;
The upper protrusion has an outer diameter larger than an inner diameter of the second ring portion, and
The lower protrusion is configured to be elastically deformable along a radial direction,
The first tubular portion is inserted into the second ring portion, and the second ring portion is disposed between the upper protrusion and the lower protrusion. One cylindrical portion is inserted, the lower protrusion is locked to the locked portion, and the second ring portion is sandwiched between the upper protrusion and the upper end of the second cylindrical portion. Thus, the method for producing a hair catcher structure is characterized in that the hair catcher structure is obtained.

According to the means 4, the hair catcher can be easily attached to the tubular member without using a special tool, and the hair catcher structure can be easily manufactured. Further, a large load is not applied to the hair catcher at the time of manufacture, and even when the hair catcher is thin, deformation and breakage can be more reliably prevented.

Furthermore, in manufacturing the hair catcher structure, for example, a method of integrating the hair catcher and the tubular member by insert molding is conceivable, but in this method, the manufacturing cost is relatively large. There is a fear. In this respect, according to the above means 4, since the hair catcher structure can be obtained by a simple method, the manufacturing cost can be effectively reduced.

Further, according to the above means 4, the first cylindrical portion is extracted from the second cylindrical portion while elastically deforming the lower protruding portion and releasing the locking of the lower protruding portion with respect to the locked portion. It is relatively easy to separate the hair catcher and the tubular member. Therefore, after separating the hair catcher and the cylindrical member, both can be cleaned, and the cleaning performance can be improved.

Means 5 . The hair catcher, the second ring with the virtual plane is formed without unevenness smooth surface shape, a virtual plane including the surface of the collector from the first ring portion including a surface of at least the collecting unit method for producing a hair catcher construction according to any one of means 1 to 4, characterized in that toward the parts side in which is a curved surface shape that is curved downward.

According to the above means 5 , the water adhering to the first ring part and the collecting part, coupled with the fact that the virtual surface including the surface of the collecting part is not uneven, travels through the collecting part and is the most in the collecting part. The water is naturally collected toward the second ring portion located on the bottom side, and the collected water is discharged through the hole. Therefore, the hair catcher can be dried relatively early. As a result, it is possible to effectively suppress propagation of germs and the like, and to improve hygiene.

  Also, since the surface of the collecting part is so shaped as to follow the belly of the finger, when the dirt of the surface of the hair catcher is wiped off with the cloth using the belly of the finger, the cloth pressed against the collecting part, etc. Can be further increased. Therefore, more dirt can be wiped off with one wiping, and the cleaning property can be further improved.

Means 6 . The said hair catcher is a manufacturing method of the hair catcher structure in any one of the means 1 thru | or 5 characterized by the said ring part and the said collection part being what consists of metals.

According to the above means 6 , the strength of the hair catcher can be improved more reliably, and damage to the hair catcher can be prevented.

In addition, according to the above means 6 , when the hair catcher has a large weight, and the hair catcher has a tapered upper annular surface that comes into contact with the contacted object , the contacted object is changed to the upper annular surface. On the other hand, the force applied toward the central axis side of the hair catcher can be made larger. Therefore, the movement of the hair catcher along the radial direction can be more effectively suppressed, and the ability to collect hair and the like can be further enhanced.

  Moreover, when the said structure of 3 is employ | adopted together, the contact pressure of the 1st ring part with respect to a to-be-contacted part can be increased further with dead weight of a hair catcher. Thereby, the adhesiveness of the 1st ring part with respect to a to-be-contacted part can be improved further, and the further improvement of collection ability, such as hair, can be aimed at.

  Furthermore, since the specific gravity of the hair catcher can be sufficiently increased, the hair catcher is hardly lifted during drainage, and hair and the like can be collected more reliably.

Means 7 . The hair catcher method for manufacturing a hair catcher construction according to any one of means 1 to 6, wherein the hole portion is of a honeycomb shape forming a hexagonal shape.

  In providing a hole in the collection part, for example, it is conceivable to form the hole between adjacent ribs by providing a plurality of ribs extending radially from the second ring part to the first ring part. . However, in this case, the gap between the ribs is relatively large on the outer peripheral side. For this reason, it is conceivable that a slight deficiency occurs in the collection ability of hair or the like on the outer peripheral side of the collection part.

  On the other hand, in order to improve the collection capability, for example, it is conceivable to make the area of each hole portion constant over almost the entire area of the collection portion by, for example, making the hole portion circular. However, in this case, in consideration of strength, if the width of the narrowest part among the parts located between the holes of the collection part is secured to some extent, as a result, the collection part The width of the widest portion among the portions located between the hole portions is remarkably increased. Therefore, the water flow area (total area of the holes) becomes small, and it may be difficult to obtain a good drainage capacity.

In this regard, according to the means 7 , the collection part has a honeycomb shape in which the hole part has a hexagonal shape. Therefore, the area of each hole can be made constant over almost the entire area of the collection portion, and the collection ability of hair and the like can be further improved. Moreover, the width | variety of the site | part located between the hole parts of a collection part becomes substantially constant, and the situation where a part of width | variety becomes remarkably large does not arise. Therefore, it is possible to effectively increase the water flow area while ensuring the strength of the collecting part, and to realize a good drainage capacity.

Means 8. Means 1 to 7 characterized in that an outer diameter of a portion of the first tubular portion located closer to the lower protrusion than the upper protrusion is smaller than an inner diameter of the second ring portion . The manufacturing method of the hair catcher structure in any one .

  According to the means 8, the portion located on the lower protrusion side of the upper protrusion part of the first cylindrical part is smoothly inserted into the second ring part without deforming the first cylindrical part. be able to. Therefore, it is very easy to insert the first tubular portion into the second ring portion and dispose the second ring portion between the upper protrusion and the lower protrusion. As a result, the hair catcher structure Manufacturing can be performed more easily. Moreover, it becomes difficult to apply a load to the hair catcher at the time of manufacture, and even if the hair catcher is thin, its deformation and breakage can be more reliably prevented.

  Hereinafter, an embodiment will be described with reference to the drawings. The drain plug device 1 is attached to a wash basin 100 as a tank body, and includes a drain port member 2 as a contacted object, a hair catcher component 9, and a plug lid 5. The washbasin 100 is a molded product, and has a drain wall 102 for discharging water in the washbasin 100 on the bottom wall portion 101 thereof.

  The drain port member 2 is formed in a cylindrical shape by resin or the like, and includes a male screw portion 21 provided on the outer peripheral surface and an annular flange portion 22 protruding from the upper end portion of the drain port member 2 to the outer peripheral side. Further, the drain port member 2 is connected to the drain port 102 in a state where the cylindrical portion having the male screw portion 21 on the outer periphery is inserted into the drain port 102 and the flange portion 22 is disposed on the bottom wall portion 101. It is inserted.

  Further, the drain port member 2 is screwed into a cylindrical mounting member 6 having a female screw portion 61 capable of screwing the male screw portion 21 on the inner periphery, and the bottom wall is interposed between the flange portion 22 and the mounting member 6. It is fixed to the washbasin 100 with the portion 101 sandwiched therebetween. An annular seal member 7 made of an elastic material such as rubber or resin is provided between the back surface of the bottom wall portion 101 and the upper end surface of the mounting member 6. The seal member 7 is sandwiched between the back surface of the bottom wall portion 101 and the upper end surface of the mounting member 6 as the drain port member 2 is screwed to the mounting member 6, and as a result, water leaks during drainage. Prevention is intended. In the present embodiment, an annular seal member 8 made of an elastic material is disposed between the flange portion 22 and the surface of the bottom wall portion 101 in order to more reliably prevent water leakage.

  In addition, on the lower side of the drain port member 2, a cylindrical pipe (not shown) serving as a flow path for water discharged from the basin 100 is attached in series. The pipe or drain port member 2 has a support shaft mechanism (not shown) provided with a rod-like support shaft (not shown) that is relatively movable in the vertical direction, and a predetermined support member (not shown). It is attached via. The support shaft mechanism is connected to a transmission member (for example, a metal wire) (not shown) for transmitting the displacement of an operation unit (not shown) constituted by a push button or the like to the support shaft. Yes. As the operation unit is operated, the support shaft is locked at the rising end (actually slightly below the rising end) via the transmission member, and the support shaft is lowered when the lock is released. To be done.

  The hair catcher component 9 includes a hair catcher 3 and a tubular member 4 attached to the hair catcher 3.

  The hair catcher 3 is made of, for example, a metal such as SUS, and as shown in FIG. 2, the hair catcher 3 is located on the annular first ring portion 31 located on the outermost periphery thereof and on the inner periphery of the first ring portion 31. An annular second ring part 32 and a collecting part 33 provided between the ring parts 31 and 32 are provided.

  Moreover, both the ring parts 31 and 32 and the collection part 33 (namely, the whole hair catcher 3) are integrally formed, and thickness is made into a predetermined value (for example, 1 mm) or less. In addition, in terms of ensuring sufficient strength, it is preferable that the thicknesses of the ring portions 31 and 32 and the collection portion 33 be 0.3 mm or more.

  Furthermore, in the present embodiment, at least the first ring portion 31 and the collection portion 33 are configured to have a certain thickness. Note that “a constant thickness” includes not only a case where the thickness is strictly constant, but also a case where there is a slight difference (for example, 0.3 mm or less) in the thickness.

  In addition, as shown in FIG. 3, a virtual surface VS (in FIG. 3, a bold line) including at least the surface of the first ring portion 31 and the surface of the collection portion 33 (in this embodiment, the entire surface of the hair catcher 3). The site | part shown) is formed in the smooth surface shape without an unevenness | corrugation. And as above-mentioned, since the 1st ring part 31 and the collection part 33 have fixed thickness, the 1st ring part 31 and the collection part 33 have protrusion on both the front and back surfaces. It has a shape that does not.

  Further, as shown in FIGS. 2 and 3, the first ring portion 31 has an upper annular surface 31A located on the outer peripheral surface and a lower side located below the upper annular surface 31A. And an annular surface 31B.

  The upper annular surface 31A has a tapered shape in which the outer diameter decreases downward. The upper annular surface 31A is placed on the drain port member 2, so that the hair catcher 3 is supported on the inner periphery of the drain port member 2 (that is, the drain channel).

  The lower annular surface 31B is configured to come into contact with the inner peripheral surface of the drain port member 2 when the upper annular surface 31A (hair catcher 3) moves with respect to the drain port member 2. In the present embodiment, the upper annular surface 31A is placed on the drain port member 2 in a state in which the central axis of the drain port member 2 and the central axis CL1 are aligned (that is, the hair catcher 3 is tilted or pivoted). When arranged at an ideal position without deviation), the distance between the lower annular surface 31B and the drain port member 2 is configured to be sufficiently small (for example, 1 mm or less). Even when the surface 31A (hair catcher 3) is slightly displaced, the lower annular surface 31B is in contact with the inner peripheral surface of the drain port member 2 so that further movement of the hair catcher 3 can be restricted. It is configured.

  Further, the lower annular surface 31B is configured to extend downward at an inclination angle α2 (°) larger than the inclination angle α1 (°) of the upper annular surface 31A. Note that, as in the present embodiment, in the cross section including the central axis CL1 of the first ring portion 31, the outline of the upper annular surface 31A and the outline of the lower annular surface 31B are each linear. In this case, the inclination angle α1 is an acute angle of angles formed by a straight line L1 obtained by extending the outline of the upper annular surface 31A and a straight line L3 orthogonal to the central axis CL1 in a cross section including the central axis CL1. Say. In addition, the inclination angle α2 is an acute angle or a right angle among the angles formed by the straight line L3 and the straight line L3 extending from the outline of the lower annular surface 31B in the cross section including the central axis CL1.

  Note that the outline of the upper annular surface 31A and the outline of the lower annular surface 31B may be curved or bent. When the outline of the upper annular surface 31A is curved or bent, the inclination angle α1 is the upper limit in the cross section including the central axis CL1 when the hair catcher 3 is arranged in an ideal state without axis deviation or inclination. It means an acute angle among the angles formed by the straight line L3 and the tangent line of the portion of the side annular surface 31A that contacts the drain port member 2. In addition, when the outline of the lower annular surface 31B is curved or bent, the inclination angle α2 is drained when the hair catcher 3 of the lower annular surface 31B is displaced in the cross section including the central axis CL1. An acute angle or a right angle among the angles formed by the straight line L3 and the tangent line of the part in contact with the mouth member 2.

  Furthermore, in the present embodiment, the lower annular surface 31B extends in a direction orthogonal to the radial direction of the first ring portion 31 (hair catcher 3) (the direction of the central axis CL1). The phrase “extends along the direction orthogonal to the radial direction of the first ring portion 31” means that the hair catcher 3 is displaced out of the lower inclined surface 31B in the cross section including the central axis CL1. It means that the tangent of the part that contacts the drain port member 2 (contacted object) is orthogonal to the straight line L3 orthogonal to the central axis CL1. However, “perpendicular to the straight line L3” means that the tangent of the portion of the lower inclined surface 31B that contacts the drain port member 2 when the hair catcher 3 is displaced is strictly the diameter of the first ring portion 31. Not only when extending along a direction orthogonal to the direction (the central axis CL1 direction) (that is, when the inclination angle α2 is 90 °), the tangent is slightly inclined with respect to the direction orthogonal to the radial direction. In some cases (for example, when the inclination angle α2 is not less than 80 ° and less than 90 °).

  In addition, the lower annular surface 31 </ b> B is configured such that the entire outer peripheral surface thereof can be separated from the inner peripheral surface of the drain port member 2. More specifically, the lower annular surface 31B has an outer diameter that is smaller than the inner diameter of the drain port member 2, and when the hair catcher 3 is disposed at an ideal position without any axial deviation or inclination, The entire outer peripheral surface of the lower annular surface 31 </ b> B is configured to be separated from the inner peripheral surface of the drain port member 2. When the entire outer peripheral surface of the lower annular surface 31B is separated from the inner peripheral surface of the drain port member 2, only the upper annular surface 31A is in contact with the drain port member 2 so that the hair catcher 3 is supported. It has come to be.

  The second ring portion 32 is configured such that the thickness thereof is slightly smaller than the thickness of the first ring portion 31 and the collection portion 33, and the tubular member 4 is disposed on the inner periphery thereof ( (See FIG. 1). The second ring portion 32 is configured such that an inner peripheral portion thereof is curved upward toward the central axis CL <b> 1, and the innermost peripheral portion of the second ring portion 32 is described later of the cylindrical member 4. In contact with the upper projection 41A. Note that the second ring portion 32 does not necessarily have a continuous annular shape, and may be a non-continuous annular shape, for example, a hole is formed in part.

  The collection unit 33 includes a plurality of holes 33A for water flow, and mainly the collection unit 33 collects hair, dust, and the like contained in the drainage. Furthermore, the virtual surface including the surface of the collection portion 33 is curved downward from the first ring portion 31 toward the second ring portion 32 and has a convex curved surface shape downward.

  Further, as shown in FIG. 4, the holes 33 </ b> A are configured to have the same hexagonal shape except for those located in the outermost peripheral portion and the innermost peripheral portion of the collecting portion 33. The portion 33 has a honeycomb shape.

  Returning to FIG. 1, the tubular member 4 includes a cylindrical first tubular portion 41 and a cylindrical second tubular portion 42 through which the first tubular portion 41 is inserted.

  The first tubular portion 41 is formed of a predetermined resin that can be elastically deformed, and a lid shaft 53 (described later) of the plug lid 5 is inserted through the inner periphery of the first tubular portion 41. Further, a plurality of groove portions 41C (see FIG. 5) that extend along the axial direction and are intermittently formed along the circumferential direction are formed on the inner peripheral surface of the first cylindrical portion 41. The groove portion 41C allows the cover shaft 53 to move smoothly up and down on the inner periphery of the first tubular portion 41. As the cover shaft 53 moves up and down, the tubular member 4 and thus the hair catcher 3 move up and down. This prevents the first ring portion 31 from floating on the drain port member 2 more reliably.

  Further, as shown in FIG. 5, the first cylindrical portion 41 has an upper protrusion 41 </ b> A and a lower protrusion 41 </ b> B, which protrude toward the outer periphery and are spaced apart in the axial direction. It has.

  The upper protrusion 41 </ b> A has an annular shape and has an outer diameter larger than the inner diameter of the second ring portion 32. The upper protrusion 41A does not necessarily have an annular shape. For example, the upper protrusion 41A may be formed by a plurality of protrusions formed intermittently along the circumferential direction. When the upper protrusion 41A is formed by a plurality of protrusions, the outer diameter of the upper protrusion 41A refers to the diameter of a virtual circle that passes through the outermost periphery of each protrusion.

  The lower protrusion 41 </ b> B has an annular shape and is provided at the lower end of the first tubular portion 41. Further, as described above, since the first tubular portion 41 is formed of an elastically deformable resin, the lower protrusion 41B can be elastically deformed along the radial direction. The lower protrusion 41B does not necessarily have an annular shape. For example, the lower protrusion 41B may be formed by a plurality of protrusions formed intermittently along the circumferential direction.

  In the present embodiment, the outer diameter (maximum outer diameter) D1 of a portion of the first cylindrical portion 41 located on the lower protrusion 41B side than the upper protrusion 41A is the inner diameter of the second ring portion 32. It is configured to be smaller than D2.

  The second cylindrical portion 42 is formed of a predetermined resin and includes an annular locked portion 42A that protrudes toward the inner peripheral side on the inner periphery thereof. Further, the engaged portion 42A has an inner diameter smaller than the outer diameter of the lower projection 41B in the inelastically deformed state, and the lower projection 41B with respect to the lower surface of the engaged portion 42A. Can be locked. Furthermore, the upper end part of the 2nd cylindrical part 42 is made into the hook shape which protruded a little in the radial direction outer side.

  In addition, the hair catcher 3 is arranged in a state where the first tubular portion 41 is disposed on the inner periphery of the second ring portion 32 of the hair catcher 3 and is sandwiched between the upper protruding portion 41B and the second tubular portion 42. It is attached to the member 4. Here, the manufacturing method of the hair catcher structure 9 which consists of the hair catcher 3 and the cylindrical member 4 is demonstrated.

  First, as shown in FIG. 6A, the first tubular portion 41 is inserted through the second ring portion 32, and the second ring portion 32 is disposed between the upper protrusion 41A and the lower protrusion 41B. Then, the first tubular portion 41 is inserted into the second tubular portion 42 from the upper end side. Then, when the insertion of the first tubular portion 41 into the second tubular portion 42 is advanced and the lower projection 41B reaches the locked portion 42A, as shown in FIG. The lower protrusion 41B is elastically deformed radially inward along the stop portion 42A. Furthermore, when the insertion of the first tubular portion 41 into the second tubular portion 42 is further advanced and the lower projection 41B passes through the locked portion 42A, the elastic deformation of the lower projection 41B is released, As shown in FIG. 5, the lower protrusion 41B is locked to the locked portion 42A. And the 2nd ring part 32 is inserted | pinched between 41 A of upper side protrusions, and the upper end part (ridge-shaped part) of the 2nd cylindrical part 42, and the hair catcher 3 will be attached with respect to the cylindrical member 4. FIG. .

  In addition, it can prevent that the 1st cylindrical part 41 comes off easily from the 2nd cylindrical part 42 by latching the lower side protrusion 41B to the to-be-latched part 42A, As a result, an upper side protrusion The hair catcher 3 can be more securely sandwiched and held by the upper end portions of the portion 41A and the second cylindrical portion 42. Particularly in the present embodiment, since the upper end portion of the second cylindrical portion 42 has a bowl shape, the hair catcher 3 is held and held more securely, and the hair catcher 3 is less likely to rattle against the cylindrical member 4. It has become.

  Further, when removing the hair catcher 3 from the tubular member 4, the lower protrusion 41B is elastically deformed radially inward, and the locking of the lower protrusion 41B with respect to the locked part 42A is released, The hair catcher 3 can be easily detached from the attachment member 4 by extracting the first tubular portion 41 from the two tubular portions 42.

  Returning to FIG. 1, the plug lid 5 is made of an umbrella-shaped portion 51 made of a resin such as POM and an elastically deformable material (for example, resin, rubber, etc.) provided on the outer peripheral side rear surface of the umbrella-shaped portion 51. An annular packing 52 is provided. The umbrella-shaped part 51 has a shape that is gently curved, and is exposed on the surface of the washbasin 100. In addition, in order to improve appearance quality, the surface of the umbrella-shaped portion 51 may be covered with a metal covering portion (not shown).

  The packing 52 is configured such that the entire outer periphery of the packing 52 contacts the drain port member 2 when the drain port 101 is closed.

  The plug lid 5 includes a rod-shaped lid shaft 53 that extends downward from the center of the back surface of the umbrella-shaped portion 51. The lower end portion of the cover shaft 53 is configured to come into contact with the upper end portion of the support shaft at least in a state where the support shaft is moved upward. The lid 5 is configured to move up and down. And whenever the said operation part is operated, the raising / lowering of the stopper lid 5 (opening / closing of the drain port 101) is performed alternately.

  As described in detail above, according to the present embodiment, the front and back surfaces of the first ring portion 31 and the collection portion 33 are in a state having no irregularities except for the hole portion 33A. Therefore, when the hair catcher 3 is cleaned, it is difficult for the cloth or brush to be caught, and good cleanability can be obtained.

  Furthermore, since the collection part 33 etc. are thin, the depth of 33 A of hole parts can be made remarkably small. Therefore, when cleaning the hair catcher 3, the cloth or brush or the like can be removed from the hole 33 </ b> A of the collection part 33 without being particularly conscious by rubbing the front or back surface of the collection part 33 with a cloth or brush. Will reach most of the depth direction of the surface forming. As a result, cleaning becomes very easy, and the cleanability can be further improved. In addition, from the viewpoint of further improving the cleanability, it is preferable to make the collection portion 33 and the like thinner, and for example, it is more preferable that the thickness of the collection portion 33 and the like is 0.8 mm or less.

In addition, since the upper annular surface 31A has a tapered shape with an outer diameter that decreases downward, the hair catcher 3 from the drain port member 2 to the upper annular surface 31A due to its own weight. a force toward the central axis side can be pressurized example Rukoto of. Therefore, the movement of the hair catcher 3 along the radial direction can be effectively suppressed. Moreover, even if some shift movement occurs in the hair catcher 3, further shift movement of the hair catcher 3 can be suppressed by the lower annular surface 31 </ b> B coming into contact with the drain port member 2. In particular, in this embodiment, since the inclination angle α2 of the lower annular surface 31B is larger than the inclination angle α1 of the upper annular surface 31A, further movement of the hair catcher 3 can be effectively restricted. As a result, it can prevent more reliably that a clearance gap arises between the 1st ring part 31 and the drain port member 2, and can further improve collection ability, such as hair and garbage.

  In addition, in the present embodiment, the lower annular surface 31B is a direction orthogonal to the radial direction of the first ring portion 31, that is, a direction substantially orthogonal to the moving direction (radial direction) when the hair catcher 3 is displaced. It is comprised so that it may extend. Therefore, further movement of the hair catcher 3 can be more effectively restricted when the lower annular surface 31 </ b> B comes into contact with the drain port member 2 along with the movement of the hair catcher 3. Thereby, it can suppress more reliably that a clearance gap arises between the 1st ring part 31 and the drain port member 2, and can further improve collection capacities, such as hair.

  Furthermore, in this embodiment, the hair catcher 3 is configured to be supported by bringing only the upper annular surface 31 </ b> A into contact with the drain port member 2. Therefore, the contact pressure of the 1st ring part 31 with respect to the drain port member 2 can be increased, and the adhesiveness of the 1st ring part 31 with respect to the drain port member 2 can be improved more. As a result, it is possible to more reliably prevent a situation in which hair or the like flows from between the first ring portion 31 and the drain port member 2, and it is possible to further enhance the collection ability of the hair or the like.

  Moreover, since the virtual surface including the surface of the collection part 33 is a curved surface shape, it couple | bonds with the 1st ring part 31 and the collection part 33 combined with the fact that the virtual surface including the surface of the collection part 33 is not uneven. The collected water is naturally collected through the collection part 33 to the second ring part 32 located on the bottom side of the collection part 33, and the collected water is discharged through the hole 33A. Will be. Therefore, the hair catcher 3 can be dried relatively early. As a result, it is possible to effectively suppress propagation of germs and the like, and to improve hygiene.

  In addition, since the surface of the collecting part 33 has a shape that conforms to the belly of the finger, when the dirt of the surface of the hair catcher 3 is wiped off with a cloth or the like using the finger belly, it is pushed against the collecting part 33. The area of the cloth to be applied can be further increased. Therefore, more dirt can be wiped off with one wiping, and the cleaning property can be further improved.

  Furthermore, since the hair catcher 3 is made of metal, the weight of the hair catcher 3 becomes large, and the force applied from the drain port member 2 to the upper annular surface 31A toward the central axis side of the hair catcher 3 is applied. Can be larger. Therefore, the displacement movement of the hair catcher 3 can be more effectively suppressed, and the ability to collect hair and the like can be further enhanced.

  Moreover, the strength of the hair catcher 3 can be improved more reliably by making the hair catcher 3 made of metal, and the hair catcher 3 can be prevented from being damaged.

  Furthermore, when the hair catcher 3 is configured to be supported by bringing only the upper annular surface 31A into contact with the drain port member 2 as in the present embodiment, the hair catcher 3 made of metal is used. The contact pressure of the first ring portion 31 with respect to the drain port member 2 can be further increased by its own weight. Thereby, the adhesiveness of the 1st ring part 31 with respect to the drain port member 2 can be improved further, and the further improvement of collection ability, such as hair, can be aimed at.

  Furthermore, since the specific gravity of the hair catcher 3 can be sufficiently increased, the hair catcher 3 is hardly lifted during drainage, and hair and the like can be collected more reliably.

  In addition, the collection part 33 has a honeycomb shape in which the hole 33A has a hexagonal shape. Therefore, the area of each hole 33A can be made constant over almost the entire area of the collection portion 33, and the collection ability of hair and the like can be further improved. Moreover, the width | variety of the site | part located between the hole parts 33A of the collection part 33 becomes substantially constant, and the situation where a part of width | variety becomes remarkably large does not arise. Therefore, it is possible to effectively increase the water flow area while ensuring the strength of the collection part 33, and it is possible to realize a good drainage capacity.

  Further, the lid shaft 53 can be smoothly moved up and down on the inner periphery of the tubular member 4 by the groove 41 </ b> C provided in the tubular member 4. As a result, it is possible to more reliably prevent the first ring portion 31 from floating from the drain port member 2 as the stopper lid 5 moves up and down, and to collect hair and the like more reliably.

  Moreover, according to this embodiment, without using a special tool etc., the hair catcher 3 can be easily attached with respect to the cylindrical member 4, and the hair catcher structure 9 can be manufactured easily. Furthermore, since the hair catcher structure 9 can be obtained by a simple method, the manufacturing cost can be effectively reduced. Further, a large load is not applied to the hair catcher 3 at the time of manufacture, and even if the hair catcher 3 is thin as in this embodiment, the deformation and breakage can be more reliably prevented.

  Further, the lower protrusion 41B is elastically deformed, and the first tubular part 41 is removed from the second tubular part 42 while releasing the locking of the lower protrusion 41B with respect to the locked part 42A. It is relatively easy to separate the catcher 3 and the cylindrical member 4. Therefore, after separating the hair catcher 3 and the cylindrical member 4, it becomes possible to clean both, and the cleaning property can be improved.

  Moreover, since the outer diameter D1 of the site | part located in the lower side protrusion 41B side rather than the upper side protrusion 41A among the 1st cylindrical parts 41 is made smaller than the internal diameter D2 of the 2nd ring part 32, it is 1st. The tubular portion 41 can be smoothly inserted into the second ring portion 32. Accordingly, it becomes very easy to insert the first tubular portion 41 into the second ring portion 32 and arrange the second ring portion 32 between the upper and lower protrusions 41A and 41B, and the hair catcher configuration. The body 9 can be manufactured more easily. Moreover, it becomes difficult to apply load with respect to the hair catcher 3 at the time of manufacture, and the deformation | transformation and damage of the hair catcher 3 can be prevented still more reliably.
