Description

開示の実施形態は、衛生陶器に関する。 The disclosed embodiment relates to sanitary ware.

従来、衛生陶器のうち、たとえば、水洗便器には、冬場などの気温低下時にボウル内の溜水の凍結を防ぐために、ヒータ付便器がある。このようなヒータ付便器では、たとえば、シート状の発熱体(ヒータ)が溜水部の裏側に配置される(たとえば、特許文献1参照)。 Conventionally, among sanitary ceramic products, for example, flush toilets include toilets equipped with heaters to prevent the water in the bowl from freezing when the temperature drops, such as in winter. In such heated toilets, for example, a sheet-shaped heating element (heater) is placed on the back side of the water-retaining portion (see, for example, Patent Document 1).

また、このようなヒータ付便器では、ヒータに給電するための電源電線をコンセントに接続する必要がある。このため、溜水部の裏側から表側まで電源電線などのコード部材を引き出すための貫通孔が形成され、さらに、コード部材を固定しつつ貫通孔に挿入される固定部材によって、コード部材が固定される。 In addition, in such heated toilets, the power cable for supplying power to the heater must be connected to an outlet. For this reason, a through hole is formed to pull out a cord member such as the power cable from the back side of the water storage section to the front side, and the cord member is fixed in place by a fixing member that is inserted into the through hole while holding the cord member in place.

特開2013-144868号公報JP 2013-144868 A

ところで、ヒータ付便器では、便器の組み立て時においてヒータを容易に取り付け可能なように、コード部材を固定した固定部材を貫通孔に挿入しやすいことが好ましい。一方で、固定部材が貫通孔から抜けにくくし、コード部材が便器から外れないようにする必要がある。 In a heated toilet, it is preferable that the fixing member to which the cord member is fixed be easily inserted into the through hole so that the heater can be easily attached when assembling the toilet. On the other hand, it is necessary to make it difficult for the fixing member to come out of the through hole, so that the cord member does not come off the toilet.

しかしながら、上記したヒータ付便器のような衛生陶器では、固定部材を、たとえば、小径化するなどして貫通孔に挿入しやすいように構成した場合は、固定部材が貫通孔から抜けやすくなってしまう。一方、固定部材を、たとえば、大径な部分を設けるなどして貫通孔から抜けにくいように構成した場合は、固定部材を貫通孔に挿入しにくくなってしまう。このように、組み立て性を考慮して固定部材を挿入しやすくする仕様と、コード保持力を確保するために固定部材を抜けにくくする仕様とは相反している。 However, in sanitary ware such as the above-mentioned heated toilet, if the fixing member is configured to be easily inserted into the through hole, for example by making it smaller in diameter, the fixing member will easily come out of the through hole. On the other hand, if the fixing member is configured to be difficult to come out of the through hole, for example by providing a large-diameter portion, the fixing member will be difficult to insert into the through hole. In this way, there is a contradiction between a specification that makes it easy to insert the fixing member in consideration of ease of assembly and a specification that makes it difficult to come out of the fixing member in order to ensure cord retention.

実施形態の一態様は、コード部材を固定しつつ貫通孔に挿入される固定部材を、貫通孔から抜けにくく、貫通孔には挿入しやすくすることができる衛生陶器を提供することを目的とする。 One aspect of the embodiment aims to provide a sanitary ware that can easily insert a fixing member, which is inserted into a through hole while fixing a cord member, into the through hole without easily coming out of the through hole.

実施形態の一態様に係る衛生陶器は、コード部材が挿通される貫通孔に挿入され、前記コード部材を固定する固定部材を備える衛生陶器であって、前記固定部材は、前記貫通孔に係止される係止部と、前記コード部材を保持する保持部と、前記係止部および前記保持部の間において径方向に変形可能な変形部とを有する。 The sanitary ware according to one embodiment is a sanitary ware having a fixing member that is inserted into a through hole through which a cord member is inserted and fixes the cord member, and the fixing member has an engaging portion that engages with the through hole, a holding portion that holds the cord member, and a deformation portion that is radially deformable between the engaging portion and the holding portion.

このような構成によれば、固定部材は、係止部によって貫通孔に係止されており、係止部が係止された状態では、たとえば、コード部材が固定部材の挿入方向とは反対の方向に引っ張られると、これに伴いコード部材を保持している保持部が係止部に向けて移動する。これにより、変形部が保持部に圧迫されて係止部と保持部との間において径方向に広がるように変形するため、変形部が貫通孔の一方端縁(内側の端縁)や内周面に接触して抜けにくいものとなる。一方で、固定部材は、貫通孔に挿入する場合には、変形部が径方向に収縮するように変形するため、挿入しやすい。このように、固定部材を、貫通孔から抜けにくく、貫通孔には挿入しやすくすることができる。 According to this configuration, the fixing member is locked in the through hole by the locking portion, and when the locking portion is locked, for example, if the cord member is pulled in the direction opposite to the insertion direction of the fixing member, the holding portion holding the cord member moves toward the locking portion. As a result, the deformed portion is pressed by the holding portion and deforms so as to expand radially between the locking portion and the holding portion, so that the deformed portion comes into contact with one edge (the inner edge) or the inner peripheral surface of the through hole and is difficult to remove. On the other hand, when the fixing member is inserted into the through hole, the deformed portion deforms so as to contract radially, making it easy to insert. In this way, the fixing member can be made difficult to remove from the through hole and easy to insert into the through hole.

また、上記した衛生陶器では、前記変形部は、前記保持部に向けて縮径するように側面がテーパ形状である。 In addition, in the above-mentioned sanitary ware, the deforming portion has a tapered side so that the diameter thereof decreases toward the retaining portion.

このような構成によれば、変形部は、保持部に向けて縮径するように側面がテーパ形状であるため、固定部材を保持部から貫通孔に挿入する場合、固定部材の挿入が容易となる。また、変形部の側面がテーパ形状であることから変形部が径方向に変形しやすいため、固定部材は、保持部によって圧迫された変形部が径方向に広がって、貫通孔から抜けにくいものとなる。 According to this configuration, the deformable portion has a tapered side so that the diameter of the deformable portion decreases toward the retaining portion, so that when the fixing member is inserted from the retaining portion into the through hole, the fixing member can be easily inserted. In addition, since the side of the deformable portion is tapered, the deformable portion is easily deformed in the radial direction, so that the deformable portion compressed by the retaining portion expands in the radial direction, making the fixing member less likely to come out of the through hole.

また、上記した衛生陶器では、前記変形部の前記側面は、前記係止部から前記径方向に大きくなる第1テーパ部と、前記保持部に向かうにつれて前記径方向に小さくなる第2テーパ部とを有する。 In addition, in the sanitary ware described above, the side surface of the deformation portion has a first tapered portion that increases in the radial direction from the locking portion, and a second tapered portion that decreases in the radial direction toward the retaining portion.

このような構成によれば、変形部の側面が第1テーパ部と第2テーパ部の2つのテーパ部を有するため、変形部は、非圧迫時において径方向の最大幅を抑えつつ、圧迫時には非圧迫時よりも径方向に大きくなる。これにより、固定部材は、挿入しやすく抜けにくいものとなる。 With this configuration, the side surface of the deformation portion has two tapered portions, a first tapered portion and a second tapered portion, so that the deformation portion reduces its maximum radial width when not compressed, while becoming larger in the radial direction when compressed than when not compressed. This makes the fixing member easy to insert and difficult to remove.

また、上記した衛生陶器では、前記第1テーパ部は、前記第2テーパ部よりも軸方向に短い。 In addition, in the above-mentioned sanitary ware, the first tapered portion is shorter in the axial direction than the second tapered portion.

このような構成によれば、第1テーパ部が第2テーパ部よりも軸方向に短いため、変形部の圧迫時には貫通孔付近で径方向に広がる。これにより、変形部が貫通孔の一方端縁(内側の端縁)や内周面に対して早期に接触し、固定部材は、貫通孔から抜けにくいものとなる。 With this configuration, the first tapered portion is shorter in the axial direction than the second tapered portion, so when the deformation portion is compressed, it expands radially near the through hole. This allows the deformation portion to come into contact with one end edge (the inner end edge) or the inner peripheral surface of the through hole early on, making it difficult for the fixing member to come out of the through hole.

また、上記した衛生陶器では、前記保持部の基端部の外径は、前記基端部に接続される前記変形部の端部の外径よりも大きい。 In addition, in the above-mentioned sanitary ware, the outside diameter of the base end of the retaining portion is larger than the outside diameter of the end of the deformed portion that is connected to the base end.

このような構成によれば、保持部の基端部によって変形部を潰しやすいため、変形部の圧迫時には径方向に広がりやすい。これにより、固定部材は、貫通孔から抜けにくいものとなる。また、変形部は、その挿入方向について先端径が小さいため、貫通孔に挿入しやすい。 With this configuration, the deformed portion is easily crushed by the base end of the holding portion, so that when the deformed portion is compressed, it tends to expand in the radial direction. This makes it difficult for the fixing member to come out of the through hole. In addition, the deformed portion is easy to insert into the through hole because the tip diameter is small in the insertion direction.

また、上記した衛生陶器では、前記係止部および前記保持部は、前記変形部よりもそれぞれ硬度が高い。 In addition, in the above-mentioned sanitary ware, the locking portion and the retaining portion each have a higher hardness than the deformable portion.

このような構成によれば、変形部は、硬度が高いものの間に挟まれているため、圧迫時には拡径しやすい。 With this configuration, the deformation section is sandwiched between hard objects, so it is easy for the diameter to expand when compressed.

また、上記した衛生陶器では、前記係止部は、前記変形部側の端部とは反対側の端部に前記貫通孔の端縁の内径よりも大径なストッパ部を有する。 In addition, in the above-mentioned sanitary ware, the locking portion has a stopper portion at the end opposite the end on the deformed portion side, the stopper portion having a diameter larger than the inner diameter of the edge of the through hole.

このような構成によれば、ストッパ部によって、係止部が貫通孔を通過してしまうのを規制することができる。これにより、固定部材は、たとえば、その挿入方向に押し込まれても、挿入方向に抜けにくいものとなる。 With this configuration, the stopper portion can prevent the locking portion from passing through the through hole. This makes it difficult for the fixing member to come out in the insertion direction, even if it is pushed in the insertion direction.

実施形態の一態様によれば、コード部材を固定しつつ貫通孔に挿入される固定部材を、貫通孔から抜けにくく、貫通孔には挿入しやすくすることができる。 According to one aspect of the embodiment, the fixing member that is inserted into the through hole while fixing the cord member can be made to be difficult to come out of the through hole and easy to insert into the through hole.

以下、添付図面を参照して、本願の開示する衛生陶器の実施形態を詳細に説明する。なお、以下に示す実施形態によりこの発明が限定されるものではない。 The following describes in detail the embodiments of the sanitary ware disclosed in this application with reference to the attached drawings. Note that the present invention is not limited to the embodiments described below.

<衛生陶器>
まず、図1を参照して実施形態に係る衛生陶器1の一例について説明する。図1は、実施形態に係る衛生陶器1の一例を示す断面斜視図である。
<Sanitary ware>
First, an example of a sanitary ware 1 according to an embodiment will be described with reference to Fig. 1. Fig. 1 is a cross-sectional perspective view showing an example of a sanitary ware 1 according to an embodiment.

なお、図1には、鉛直上向き(上方)を正方向とするZ軸を含む3次元の直交座標系を示している。以下では、説明の便宜上、X軸の正方向を右方、X軸の負方向を左方、Y軸の正方向を前方、Y軸の負方向を後方と規定している。このため、X軸方向を左右方向、Y軸方向を前後方向、Z軸方向を上下方向という場合がある。 Note that Figure 1 shows a three-dimensional Cartesian coordinate system including the Z axis, with the positive direction being vertically upward (upward). For ease of explanation, the positive direction of the X axis is defined as the right, the negative direction of the X axis as the left, the positive direction of the Y axis as the forward direction, and the negative direction of the Y axis as the backward direction. For this reason, the X axis direction may be referred to as the left-right direction, the Y axis direction as the front-back direction, and the Z axis direction as the up-down direction.

また、以下では、衛生陶器1として、水洗大便器(以下、「便器」という)を例に説明する。なお、衛生陶器1としては、この他にも、小便器や手洗い器など、様々なものがある。 In the following, a flush toilet bowl (hereafter referred to as a "toilet bowl") will be used as an example of the sanitary ware 1. However, there are various other types of sanitary ware 1, such as urinals and hand washing basins.

図1に示すように、衛生陶器である便器1は、トイレ室の床面に設置される、いわゆる床置き式の便器である。なお、便器1は、トイレ室の壁面に取り付けられる、いわゆる壁掛け式の便器でもよい。便器1は、たとえば、洗い落とし(ウォッシュダウン)式の便器でもよいし、サイホン式の便器でもよいし、これらの他の便器でもよい。なお、本実施形態における便器1(便器本体1a)は、陶器製であることが好ましいが、これに限定されるものではなく、樹脂製等であってもよい。 As shown in FIG. 1, the toilet bowl 1, which is a sanitary ceramic ware, is a so-called floor-standing toilet bowl that is installed on the floor of a toilet room. The toilet bowl 1 may also be a so-called wall-hung toilet bowl that is attached to the wall of a toilet room. The toilet bowl 1 may be, for example, a wash-down toilet bowl, a siphon toilet bowl, or any other type of toilet bowl. The toilet bowl 1 (toilet body 1a) in this embodiment is preferably made of ceramic, but is not limited to this and may be made of resin, etc.

便器1は、たとえば、洗い落とし式の場合、給水源である貯水タンクに接続された給水配管(図示せず)から便器本体1aに洗浄水が供給される。便器1は、汚物を洗浄水と共に排水配管(図示せず)へ排出する。 For example, in the case of a wash-down toilet 1, flushing water is supplied to the toilet body 1a from a water supply pipe (not shown) connected to a water tank, which is a water supply source. The toilet 1 discharges waste matter together with the flushing water into a drain pipe (not shown).

便器本体1aは、ボウル部2と、リム部3と、吐水部4と、溜水部5と、排出部6とを備える。ボウル部2は、ボウル形状に形成され、ボウル面で汚物を受ける。リム部3は、ボウル部2の上縁部に設けられる。リム部3は、洗浄水がボウル部2の外側に飛び出さないように、ボウル部2の内側に向けたオーバーハング形状に形成される。 The toilet body 1a comprises a bowl section 2, a rim section 3, a water discharge section 4, a water storage section 5, and a discharge section 6. The bowl section 2 is formed in a bowl shape, and the bowl surface receives waste. The rim section 3 is provided on the upper edge of the bowl section 2. The rim section 3 is formed in an overhanging shape toward the inside of the bowl section 2 to prevent flushing water from splashing out to the outside of the bowl section 2.

吐水部4は、給水源から供給される洗浄水を吐水口(図示せず)からボウル部2へ吐出する。溜水部5は、ボウル部2の下方に設けられる。溜水部5は、洗浄水の一部が溜まり(溜まった水を「溜水」という)、溜水が封水として機能することで、排出部6から臭気などがボウル部2側へ逆流することを防止する。 The water discharge section 4 discharges cleaning water supplied from a water supply source from a water outlet (not shown) into the bowl section 2. The water storage section 5 is provided below the bowl section 2. A portion of the cleaning water accumulates in the water storage section 5 (the accumulated water is called "accumulated water"), and the accumulated water functions as a water seal to prevent odors and the like from flowing back into the bowl section 2 from the discharge section 6.

排出部6には、排出路(図示せず)が形成される。排出路は、トラップ形状に形成された部分(トラップ管路)を有する。排出路は、排水配管に接続される。便器本体1aは、吐水部4からボウル部2へ洗浄水を吐出し、汚物を排出部6から排水配管へ排出する。 A discharge passage (not shown) is formed in the discharge section 6. The discharge passage has a portion formed in a trap shape (trap pipe). The discharge passage is connected to a drain pipe. The toilet body 1a discharges flushing water from the water discharge section 4 to the bowl section 2, and discharges waste from the discharge section 6 to the drain pipe.

また、便器1は、ヒータ7をさらに備える。ヒータ7は、たとえば、シート状の発熱体である。ヒータ7は、溜水部5の溜水の凍結を防ぐために、溜水部5の外側の面である裏面および排出部6の外周面の一部に取り付けられる。ヒータ7は、たとえば、矩形や円形状シートであり、発熱することで、取り付けられた箇所を温めることができる。ヒータ7としては、たとえば、シートに電熱線が張り巡らされたものがある。 The toilet 1 further includes a heater 7. The heater 7 is, for example, a sheet-shaped heating element. The heater 7 is attached to the back surface, which is the outer surface of the water storage section 5, and to a part of the outer peripheral surface of the discharge section 6 in order to prevent the water stored in the water storage section 5 from freezing. The heater 7 is, for example, a rectangular or circular sheet, and can warm the area where it is attached by generating heat. An example of the heater 7 is a sheet with heating wires stretched across it.

ヒータ7は、たとえば、接着剤で取り付けられる。接着剤は、熱伝導性のよいものが好ましい。 The heater 7 is attached, for example, with an adhesive. It is preferable to use an adhesive with good thermal conductivity.

なお、溜水部5の裏面および排出部6の外周面のうち、ヒータ7が取り付けられた箇所とは異なる箇所に、ボウル部2よりも熱伝導性のよい非自己発熱性の伝熱シートが取り付けられてもよい。この場合、伝熱シートを、ヒータ7に対して部分的に接触させている。伝熱シートは、たとえば、陶器製のボウル部2よりも熱伝導性のよい金属フィルムである。伝熱シートは、ヒータ7に接触していることでヒータ7の熱が伝達され、取り付けられた箇所を温めることができる。 A non-self-heating heat transfer sheet with better thermal conductivity than the bowl section 2 may be attached to the back surface of the water storage section 5 and the outer peripheral surface of the discharge section 6 at a location other than where the heater 7 is attached. In this case, the heat transfer sheet is in partial contact with the heater 7. The heat transfer sheet is, for example, a metal film with better thermal conductivity than the ceramic bowl section 2. By being in contact with the heater 7, the heat from the heater 7 is transferred to the heat transfer sheet, and the location where the heat transfer sheet is attached can be warmed.

伝熱シートを備える場合、伝熱シートは、たとえば、ヒータ7と同様、熱伝導性のよい接着剤で取り付けられる。 If a heat transfer sheet is provided, the heat transfer sheet is attached, for example, with an adhesive having good thermal conductivity, similar to the heater 7.

また、便器1は、防露材8をさらに備えてもよい。防露材8は、ボウル部2、溜水部5、排出部6の一部にかけて、これらの裏側に設けられる。防露材8は、便器本体1aの裏側が結露して落下する水滴を受けるものである。 The toilet 1 may further include a dew prevention material 8. The dew prevention material 8 is provided on the back side of the bowl portion 2, the water storage portion 5, and part of the discharge portion 6. The dew prevention material 8 is intended to catch water droplets that condense on the back side of the toilet body 1a and fall.

便器1では、ヒータ7に給電するための電源電線を、たとえば、トイレ室の壁面などに設けられたコンセントに接続する必要がある。このため、便器1は、溜水部5の裏側から表側へ電源電線などのコード部材9を引き出すための貫通孔10(図2参照)を備える。なお、「裏側」とは、便器本体1aが設置された状態で、便器本体1aにおける外部に露出しない側のことをいい、「表側」とは、便器本体1aが設置された状態で、便器本体1aにおける外部に露出する側のことをいう。 In the toilet 1, the power cable for supplying power to the heater 7 must be connected to an outlet provided, for example, on the wall of the toilet room. For this reason, the toilet 1 has a through hole 10 (see FIG. 2) for pulling out a cord member 9 such as a power cable from the back side of the water storage section 5 to the front side. Note that the "back side" refers to the side of the toilet body 1a that is not exposed to the outside when the toilet body 1a is installed, and the "front side" refers to the side of the toilet body 1a that is exposed to the outside when the toilet body 1a is installed.

貫通孔10は、便器本体1aを形成する陶器製の壁1bの所定の箇所(以下、この箇所を「固定部」という)に形成されている。貫通孔10は、陶器(壁1b)を貫通している孔である。貫通孔10には、コード部材9が挿通される。 The through hole 10 is formed at a predetermined location (hereinafter, this location is referred to as the "fixed portion") of the ceramic wall 1b that forms the toilet body 1a. The through hole 10 is a hole that penetrates the ceramic (wall 1b). The cord member 9 is inserted into the through hole 10.

さらに、便器1は、コード部材9を固定部11に形成された貫通孔10に固定するための固定部材12を備える。固定部材12は、貫通孔10に挿入されることで、貫通孔10に取り付けられる。 The toilet 1 further includes a fixing member 12 for fixing the cord member 9 to the through hole 10 formed in the fixing portion 11. The fixing member 12 is attached to the through hole 10 by being inserted into the through hole 10.

ここで、固定部材12は、便器1の組み立て性を考慮すると、貫通孔10に挿入しやすいものであることが好ましい。一方で、固定部材12は、貫通孔10から抜けにくいものである必要がある。 Here, in consideration of the ease of assembly of the toilet 1, it is preferable that the fixing member 12 is easy to insert into the through hole 10. On the other hand, the fixing member 12 needs to be difficult to come out of the through hole 10.

そして、組み立て性を考慮して固定部材を挿入しやすくする仕様と、コード保持力を確保するために固定部材を抜けにくくする仕様とは相反している。このため、いずれの要求を満たすためには、たとえば、複数の部品を用いるなど、特別な対策が必要となる。 The requirement to make the fixing member easy to insert for ease of assembly and the requirement to make the fixing member difficult to remove in order to ensure cord retention are contradictory. For this reason, special measures, such as using multiple parts, are needed to satisfy both requirements.

また、陶器製の便器1(便器本体1a)に貫通孔10を形成する場合、便器本体1aの成形時において型を抜きやすくするために、貫通孔10を構成する内周面10a(図5参照)に傾斜が必要となる。このように、陶器の場合は、表側と裏側とで貫通孔10の内径が異なることが頻繁にある。 When forming a through hole 10 in a ceramic toilet bowl 1 (toilet bowl body 1a), the inner peripheral surface 10a (see Figure 5) that constitutes the through hole 10 needs to be inclined in order to make it easier to remove the mold when forming the toilet bowl body 1a. Thus, in the case of ceramic, the inner diameter of the through hole 10 often differs between the front and back sides.

このため、本実施形態では、固定部材12が、貫通孔10に挿入された状態では貫通孔10から抜けにくく、貫通孔10に挿入する場合には挿入しやすいように構成している。また、このような固定部材12は、陶器製の便器1に形成される貫通孔10に対して特に有効なものとなる。 For this reason, in this embodiment, the fixing member 12 is configured so that it is difficult for the fixing member 12 to come out of the through hole 10 when inserted into the through hole 10, but is easy to insert into the through hole 10. In addition, such a fixing member 12 is particularly effective for a through hole 10 formed in a ceramic toilet bowl 1.

<固定部材>
次に、図2~5を参照して実施形態に係る固定部材12について説明する。図2は、コード部材9および固定部材12を示す側面図である。図3は、固定部材12を示す斜視図である。図4は、(a)固定部材12を示す平面図、(b)固定部材12を示す側面図である。図5は、(a)固定部材12を貫通孔10に挿入する場合の変形部15の動作説明図(側面図)、(b)固定部材12が貫通孔10から引き抜かれようとした場合の変形部15の動作説明図(側面図)である。
<Fixing member>
Next, the fixing member 12 according to the embodiment will be described with reference to Figures 2 to 5. Figure 2 is a side view showing the cord member 9 and the fixing member 12. Figure 3 is a perspective view showing the fixing member 12. Figure 4 is (a) a plan view showing the fixing member 12, and (b) a side view showing the fixing member 12. Figure 5 is (a) an explanatory diagram (side view) of the operation of the deformation portion 15 when the fixing member 12 is inserted into the through hole 10, and (b) an explanatory diagram (side view) of the operation of the deformation portion 15 when the fixing member 12 is to be pulled out of the through hole 10.

図2に示すように、固定部材12は、コード部材9を固定しつつ、陶器製の壁1bに形成された貫通孔10に挿入される。 As shown in FIG. 2, the fixing member 12 is inserted into the through hole 10 formed in the ceramic wall 1b while fixing the cord member 9.

コード部材9は、固定部材12によって、固定部11において固定される。コード部材9は、一方の端部にコネクタ91を有する。コネクタ91は、ヒータ7から延びるコード71に接続される。このように、コード部材9は、コネクタ91を介して、ヒータ7に接続される。なお、コード部材9は、他方の端部に、たとえば、トイレ室内のコンセントに接続するためのACアダプタなどを有する。 The cord member 9 is fixed at the fixing portion 11 by the fixing member 12. The cord member 9 has a connector 91 at one end. The connector 91 is connected to the cord 71 extending from the heater 7. In this way, the cord member 9 is connected to the heater 7 via the connector 91. The cord member 9 has, at the other end, an AC adapter or the like for connecting to an outlet in the toilet room, for example.

コード部材9は、固定部材12の軸方向に貫通するように形成された挿通孔12a(図3参照)に挿通され、後述する保持部14(図3および図4参照)によって保持される。コード部材9は、接着剤などで保持部14に接着される。 The cord member 9 is inserted through an insertion hole 12a (see FIG. 3) formed so as to penetrate the fixing member 12 in the axial direction, and is held by a holding portion 14 (see FIG. 3 and FIG. 4) described later. The cord member 9 is adhered to the holding portion 14 with an adhesive or the like.

図3および図4に示すように、固定部材12は、係止部13と、保持部14と、変形部15とを有する。係止部13と、保持部14および変形部15は、固定部材12の軸方向に沿って配置される。 As shown in Figures 3 and 4, the fixing member 12 has an engagement portion 13, a holding portion 14, and a deformation portion 15. The engagement portion 13, the holding portion 14, and the deformation portion 15 are arranged along the axial direction of the fixing member 12.

係止部13は、固定部材12が貫通孔10に取り付けられた状態で、貫通孔10に挿入されている円筒形状の部位である。係止部13は、一方の端部に、貫通孔10の一方の端縁の内径よりも大径に形成されたストッパ部131を有する。ストッパ部131は、係止部13の円筒形状の本体部に対してフランジ状に形成される。係止部13は、貫通孔10に挿入されることで、貫通孔10に係止される。 The locking portion 13 is a cylindrical portion that is inserted into the through hole 10 when the fixing member 12 is attached to the through hole 10. The locking portion 13 has a stopper portion 131 at one end that is formed with a diameter larger than the inner diameter of one edge of the through hole 10. The stopper portion 131 is formed in a flange shape relative to the cylindrical main body portion of the locking portion 13. The locking portion 13 is locked to the through hole 10 by being inserted into the through hole 10.

保持部14は、上記したように、コード部材9(図2参照)を保持する。保持部14は、円筒形状に形成される。図4(a)に示すように、保持部14は、コード挿通孔14aを有する。コード挿通孔14aは、上記した挿通孔12aの一部を構成する孔であり、挿通孔12aの他の部位よりも小径に形成される。コード部材9は、たとえば、このコード挿通孔14aに挿通された状態で接着剤などで接着されることで、コード挿通孔14aに固着される。このように、コード部材9はコード挿通孔14aと接着されるため、保持部14は、コード部材9の動きと連動して動作する。 As described above, the holding portion 14 holds the cord member 9 (see FIG. 2). The holding portion 14 is formed in a cylindrical shape. As shown in FIG. 4(a), the holding portion 14 has a cord insertion hole 14a. The cord insertion hole 14a is a hole that constitutes part of the insertion hole 12a described above, and is formed with a smaller diameter than other parts of the insertion hole 12a. The cord member 9 is fixed to the cord insertion hole 14a, for example, by being inserted into the cord insertion hole 14a and adhered thereto with an adhesive or the like. In this way, the cord member 9 is adhered to the cord insertion hole 14a, and therefore the holding portion 14 operates in conjunction with the movement of the cord member 9.

変形部15は、係止部13と保持部14との間に配置される。変形部15は、係止部13と保持部14との間において径方向に変形可能である。すなわち、変形部15は、外力が加わることで、径方向に広がったり、径方向に縮んだりすることができる。なお、「径方向」とは、固定部材12の軸方向と直交する方向である。また、「径方向」は、固定部材12の径方向であるとともに、係止部13、保持部14および変形部15のそれぞれの径方向である。なお、「軸方向」についても「径方向」の場合と同様、固定部材12の軸方向であるとともに、係止部13、保持部14および変形部15のそれぞれの軸方向である。 The deformation portion 15 is disposed between the locking portion 13 and the holding portion 14. The deformation portion 15 is capable of radial deformation between the locking portion 13 and the holding portion 14. That is, the deformation portion 15 can expand or contract radially when an external force is applied. The "radial direction" is a direction perpendicular to the axial direction of the fixing member 12. The "radial direction" is the radial direction of the fixing member 12, as well as the radial direction of each of the locking portion 13, the holding portion 14, and the deformation portion 15. The "axial direction" is the same as the "radial direction", and is the axial direction of the fixing member 12, as well as the axial direction of each of the locking portion 13, the holding portion 14, and the deformation portion 15.

変形部15は、径方向の最大幅が少なくとも貫通孔10の最小幅よりも大きくなるように形成される。 The deformation portion 15 is formed so that its maximum radial width is at least greater than the minimum width of the through hole 10.

また、図4(b)に示すように、変形部15は、側面15aがテーパ形状である。側面15aは、側面視において保持部14に向けて縮径するように形成される。また、側面15aは、側面視において、外方に向けて凸となるような曲線(曲面)で形成される。なお、側面15aは、側面視において直線で形成されてもよい。 As shown in FIG. 4(b), the deforming portion 15 has a tapered side surface 15a. The side surface 15a is formed so as to decrease in diameter toward the holding portion 14 in side view. The side surface 15a is formed with a curve (curved surface) that is convex outward in side view. Note that the side surface 15a may be formed with a straight line in side view.

変形部15の側面15aは、第1テーパ部15aaと、第2テーパ部15abとを有する。第1テーパ部15aaは、係止部13から保持部14側に向かうにつれて、すなわち、一方の端部から他方の端部側に向かうにつれて径方向に大きくなる傾斜面である。第1テーパ部15aaは、後述する第2テーパ部15abよりも軸方向に短くなるように形成される。 The side surface 15a of the deformation portion 15 has a first tapered portion 15aa and a second tapered portion 15ab. The first tapered portion 15aa is an inclined surface that becomes larger in the radial direction from the locking portion 13 toward the holding portion 14, that is, from one end toward the other end. The first tapered portion 15aa is formed so as to be shorter in the axial direction than the second tapered portion 15ab, which will be described later.

第2テーパ部15abは、第1テーパ部15aaの軸方向の終端部から保持部14に向かうにつれて、すなわち、他方の端部に向かうにつれて径方向に小さくなる傾斜面である。 The second tapered portion 15ab is an inclined surface that becomes smaller in the radial direction from the axial end of the first tapered portion 15aa toward the retaining portion 14, i.e., toward the other end.

また、図4(b)に示すように、保持部14の基端部14bの外径は、この基端部14bに接続される変形部15の他方の端部の外径よりも大きい。 Also, as shown in FIG. 4(b), the outer diameter of the base end 14b of the retaining portion 14 is larger than the outer diameter of the other end of the deformation portion 15 connected to the base end 14b.

固定部材12は、たとえば、ゴムや熱可塑性エラストマを材料として、係止部13、保持部14および変形部15が一体となるように形成される。固定部材12は、たとえば、射出成形によって形成される。また、固定部材12は、係止部13および保持部14が変形部15よりもそれぞれ硬度が高い。なお、コード部材9(図2参照)を保持する保持部14が最も硬度が高いことが好ましい。これにより、コード部材9の保持力が高まる。 The fixing member 12 is formed, for example, from rubber or a thermoplastic elastomer, so that the locking portion 13, the holding portion 14, and the deformation portion 15 are integrated. The fixing member 12 is formed, for example, by injection molding. The locking portion 13 and the holding portion 14 of the fixing member 12 are each harder than the deformation portion 15. It is preferable that the holding portion 14 that holds the cord member 9 (see Figure 2) has the highest hardness. This increases the holding force of the cord member 9.

図5(a)に示すように、固定部材12は、貫通孔10に挿入される場合、壁1bの表側から挿入される。固定部材12は、貫通孔10に挿入される場合には、挿入方向D1に進行する。この場合、変形部15が、貫通孔10の内側(裏側)の端縁に接触して径方向の内側に圧迫され、図中の矢印A1で示すように、径方向に小さくなる(縮径する)ように変形する。 As shown in FIG. 5(a), when the fixing member 12 is inserted into the through hole 10, it is inserted from the front side of the wall 1b. When the fixing member 12 is inserted into the through hole 10, it advances in the insertion direction D1. In this case, the deformation portion 15 comes into contact with the edge on the inside (back side) of the through hole 10 and is compressed radially inward, and deforms so as to become smaller radially (reduced in diameter) as indicated by the arrow A1 in the figure.

固定部材12は、貫通孔10に挿入されると、係止部13が貫通孔10に係止された状態となる。固定部材12は、係止部13が貫通孔10に係止された状態では、変形部15が元の形状に戻っている。固定部材12は、ストッパ部131が貫通孔10の内側(裏側)の端縁に接触することで、挿入方向D1への移動が規制されている。 When the fixing member 12 is inserted into the through hole 10, the locking portion 13 is locked in the through hole 10. When the locking portion 13 is locked in the through hole 10, the deformation portion 15 of the fixing member 12 returns to its original shape. The stopper portion 131 comes into contact with the inner edge (back side) of the through hole 10, restricting the movement of the fixing member 12 in the insertion direction D1.

図5(b)に示すように、固定部材12は、たとえば、コード部材9を引っ張る向きに力が加えられ、コード部材9が貫通孔10から引き抜かれようとした場合、壁1bの裏側から表側に向けた引き抜き方向D2に進行しようとする。この場合、変形部15が貫通孔10の外側の端部や内周面10aに接触して引き抜き方向D2への移動が規制されている。変形部15の移動が規制された状態でコード部材9に固着されている保持部14が引き抜き方向D2に進行しようとすることで、図中の矢印Bで示すように、係止部13と保持部14との間に位置する変形部15が保持部14に引き抜き方向D2に圧迫される。 As shown in FIG. 5(b), when a force is applied to the fixing member 12 in a direction that pulls the cord member 9, for example, and the cord member 9 is to be pulled out of the through hole 10, the fixing member 12 attempts to move in the pulling direction D2 from the back side of the wall 1b to the front side. In this case, the deformation portion 15 contacts the outer end or the inner peripheral surface 10a of the through hole 10, restricting the movement in the pulling direction D2. With the movement of the deformation portion 15 restricted, the holding portion 14, which is fixed to the cord member 9, attempts to move in the pulling direction D2, and the deformation portion 15, which is located between the locking portion 13 and the holding portion 14, is pressed by the holding portion 14 in the pulling direction D2, as shown by the arrow B in the figure.

変形部15は、保持部14に圧迫されることで、軸方向に潰れて、図中の矢印A2で示すように、径方向に大きくなる(拡径する)ように変形する。これにより、変形部15は、貫通孔10の外側の端部や内周面10aに接触して、コード部材9を引っ張る向きの力に抗して引き抜き方向D2への移動が規制される。 When the deformation portion 15 is pressed by the holding portion 14, it is crushed in the axial direction and deformed so as to become larger in the radial direction (expand in diameter) as shown by the arrow A2 in the figure. As a result, the deformation portion 15 comes into contact with the outer end and the inner peripheral surface 10a of the through hole 10, and movement in the pulling direction D2 against the force pulling the cord member 9 is restricted.

上記した実施形態によれば、固定部材12は、係止部13によって貫通孔10に係止されており、係止部13が係止された状態では、たとえば、コード部材9が固定部材12の挿入方向D1とは反対の引き抜き方向D2に引っ張られると、コード部材9を保持している保持部14が係止部13に向けて移動する。これにより、変形部15が保持部14に圧迫されて係止部13と保持部14との間において径方向に広がるように変形するため、変形部15が貫通孔10の内側(裏側)の端縁や内周面10aに接触して抜けにくいものとなる。 According to the embodiment described above, the fixing member 12 is locked in the through hole 10 by the locking portion 13, and when the locking portion 13 is locked, for example, when the cord member 9 is pulled in the pull-out direction D2 opposite to the insertion direction D1 of the fixing member 12, the holding portion 14 holding the cord member 9 moves toward the locking portion 13. As a result, the deformation portion 15 is compressed by the holding portion 14 and deforms so as to expand radially between the locking portion 13 and the holding portion 14, so that the deformation portion 15 comes into contact with the edge or inner peripheral surface 10a on the inside (back side) of the through hole 10 and is difficult to come out.

一方で、固定部材12は、貫通孔10に挿入される場合には、変形部15が径方向に収縮するように変形するため、挿入しやすい。 On the other hand, when the fixing member 12 is inserted into the through hole 10, the deformation portion 15 deforms so as to contract radially, making it easy to insert.

このように、上記した実施形態によれば、固定部材12を、貫通孔10から抜けにくく、貫通孔10には挿入しやすくすることができる。 In this way, according to the above-described embodiment, the fixing member 12 is less likely to come out of the through hole 10 and can be easily inserted into the through hole 10.

また、変形部15は、保持部14に向けて縮径するように側面15aがテーパ形状であるため、固定部材12を保持部14から貫通孔10に挿入する場合、固定部材12の挿入が容易となる。また、変形部15の側面15aがテーパ形状であることから変形部15が径方向に変形しやすいため、固定部材12は、保持部14によって圧迫された変形部15が径方向に広がって、貫通孔10から抜けにくいものとなる。 In addition, since the side surface 15a of the deformation portion 15 is tapered so that the diameter of the deformation portion 15 decreases toward the holding portion 14, when the fixing member 12 is inserted from the holding portion 14 into the through hole 10, the fixing member 12 can be easily inserted. In addition, since the side surface 15a of the deformation portion 15 is tapered, the deformation portion 15 is easily deformed in the radial direction, and therefore the deformation portion 15 compressed by the holding portion 14 expands in the radial direction, making the fixing member 12 less likely to come out of the through hole 10.

また、変形部15の側面15aが第1テーパ部と第2テーパ部の2つのテーパ部を有するため、変形部15は、非圧迫時において径方向の最大幅を抑えつつ、圧迫時には非圧迫時よりも径方向に大きくなる。これにより、固定部材12は、挿入しやすく抜けにくいものとなる。 In addition, since the side surface 15a of the deformation portion 15 has two tapered portions, a first tapered portion and a second tapered portion, the deformation portion 15 suppresses its maximum radial width when not compressed, while becoming larger in the radial direction when compressed than when not compressed. This makes the fixing member 12 easy to insert and difficult to remove.

また、第1テーパ部15aaが第2テーパ部15abよりも軸方向に短いため、変形部15の圧迫時には貫通孔10付近で径方向に広がる。これにより、変形部15が貫通孔10の内側(裏側)の端縁や内周面10aに対して早期に接触し、固定部材12は、貫通孔10から抜けにくいものとなる。 In addition, because the first tapered portion 15aa is shorter in the axial direction than the second tapered portion 15ab, when the deformation portion 15 is compressed, it expands in the radial direction near the through hole 10. As a result, the deformation portion 15 comes into contact with the inner edge (back side) of the through hole 10 and the inner circumferential surface 10a at an early stage, and the fixing member 12 is less likely to come out of the through hole 10.

また、第2テーパ部15abが軸方向に長いため、固定部材12を貫通孔10に挿入する場合には、挿入しやすい。 In addition, since the second tapered portion 15ab is long in the axial direction, it is easy to insert the fixing member 12 into the through hole 10.

また、保持部14の基端部14bによって変形部15を潰しやすいため、変形部15の圧迫時には径方向に広がりやすい。これにより、固定部材12は、貫通孔10から抜けにくいものとなる。また、変形部15は、その挿入方向D1について先端径が小さいため、貫通孔10に挿入しやすい。 In addition, since the base end 14b of the holding portion 14 easily crushes the deformed portion 15, the deformed portion 15 tends to expand radially when compressed. This makes it difficult for the fixing member 12 to come out of the through hole 10. In addition, since the tip diameter of the deformed portion 15 is small in the insertion direction D1, it is easy to insert into the through hole 10.

また、変形部15は、硬度がより高い係止部13と保持部14との間に挟まれているため、圧迫時には拡径しやすい。さらに、係止部13および保持部14は円筒形状に構成されているため、係止部13および保持部14は軸方向に変形しにくくなっており、変形部15の変形に効果的に作用する。 In addition, since the deformation portion 15 is sandwiched between the locking portion 13 and the holding portion 14, which have a higher hardness, the diameter of the deformation portion 15 is easily expanded when compressed. Furthermore, since the locking portion 13 and the holding portion 14 are configured in a cylindrical shape, the locking portion 13 and the holding portion 14 are less likely to deform in the axial direction, which effectively acts to deform the deformation portion 15.

また、ストッパ部131によって、係止部13が貫通孔10を通過してしまうのを規制することができる。これにより、固定部材12は、たとえば、その挿入方向D1に押し込まれても、挿入方向D1に抜けにくいものとなる。 The stopper portion 131 can also prevent the locking portion 13 from passing through the through hole 10. This makes it difficult for the fixing member 12 to come out in the insertion direction D1, even if it is pushed in the insertion direction D1.

なお、上記した実施形態では、貫通孔10が便器1(便器本体1a)の表側よりも裏側の方が大径な孔であるが、これに限定されず、貫通孔10が裏側よりも表側が大径な孔であってもよい。また、貫通孔10は、表側と裏側が等しい径となる孔であってもよい。これらの貫通孔10に上記した固定部材12を用いても、挿入しやすく、抜けにくいものとなる。 In the above embodiment, the through hole 10 is a hole with a larger diameter on the back side than on the front side of the toilet 1 (toilet body 1a), but this is not limited to this, and the through hole 10 may be a hole with a larger diameter on the front side than on the back side. The through hole 10 may also be a hole with the same diameter on the front and back sides. Even if the fixing member 12 described above is used in these through holes 10, they will be easy to insert and difficult to remove.

さらなる効果や変形例は、当業者によって容易に導き出すことができる。このため、本発明のより広範な態様は、以上のように表しかつ記述した特定の詳細および代表的な実施形態に限定されるものではない。したがって、添付の特許請求の範囲およびその均等物によって定義される総括的な発明の概念の精神または範囲から逸脱することなく、様々な変更が可能である。 Further advantages and modifications may readily occur to those skilled in the art. Therefore, the invention in its broader aspects is not limited to the specific details and representative embodiments shown and described above. Accordingly, various modifications may be made without departing from the spirit or scope of the general inventive concept as defined by the appended claims and equivalents thereof.
