Description
本発明の態様は、一般的に、水栓装置に関する。 Aspects of the present invention generally relate to water faucet devices.
従来において、水栓本体に対して吐水ヘッドが着脱可能な水栓装置が知られている（例えば、特許文献１参照）。こういった水栓装置においては、特許文献１のようにホースが金属製で蛇腹状に形成されるものが広く知られている。 Conventionally, faucet devices in which the spout head is detachable from the faucet body are known (see, for example, Patent Document 1). Among such faucet devices, those in which the hose is made of metal and formed into an accordion shape, as in Patent Document 1, are widely known.
特許文献１のようにホースを金属製にすると一定の耐久性を確保しやすい一方で、吐水ヘッドを引き出すときに水栓本体の内管と金属製のホースとの接触音が大きくなり、使用者に不快感を与えてしまう。また、引き出しできる長さのホースを金属で構成することで、コストが高くなる。 While making the hose out of metal, as in Patent Document 1, makes it easier to ensure a certain level of durability, the noise made by the metal hose coming into contact with the inner tube of the faucet body when the spout head is pulled out is loud, causing discomfort to the user. Furthermore, making the hose of a length that can be pulled out out of metal increases costs.
ここで、可撓性を有する樹脂製のホースにすることで、ホースを金属製にする場合に比べて、吐水ヘッドを引き出すときの水栓本体の内管とホースとの接触音を抑えることができ、コストも抑えることができるが、ホースの耐久性が低下してしまうおそれがある。特に、引き出した吐水ヘッドを様々な方向に取り回して使用する水栓装置においては、ホースにかかる負荷が大きいため、ホースの耐久性が低いと最悪の場合、ホースが破れてしまうおそれがある。 By using a flexible resin hose, the noise caused by the hose coming into contact with the inner tube of the faucet body when the spout head is pulled out can be reduced compared to using a metal hose, and costs can also be reduced, but there is a risk that the durability of the hose will be reduced. In particular, in faucet devices where the pulled-out spout head must be moved in various directions, the hose is subjected to a large load, and if the hose's durability is low, it could, in the worst case scenario, break.
ホースの厚みを厚くすることで耐久性を向上させることも可能だが、ホースの厚みが厚過ぎると吐水ヘッドを引き出して使用するときの吐水ヘッドの取り回しがしにくくなり、吐水ヘッドの操作性が悪くなってしまう。 It is possible to improve durability by making the hose thicker, but if the hose is too thick, it will be difficult to handle the spout head when pulling it out for use, making it difficult to operate.
本発明は、かかる課題の認識に基づいてなされたものであり、吐水ヘッドを引き出して使用するときの樹脂製ホースの耐久性の確保と吐水ヘッドの操作性との両立を実現した吐水装置を提供することを目的とする。 The present invention was developed in recognition of this issue, and aims to provide a water discharge device that ensures both the durability of the plastic hose when the water discharge head is pulled out for use and the operability of the water discharge head.
実施形態の一態様に係る水栓装置は、水栓本体と、前記水栓本体に対して着脱自在である吐水ヘッドと、前記吐水ヘッドに対して通水可能に接続されて可撓性を有する樹脂製のホース部と、を備えた水栓装置であって、前記吐水ヘッドは、吐水口を有するヘッド本体と、前記ホース部内に挿入される接続部と、を備え、前記ホース部内において前記接続部の端部に取り付けられる補強部材を有することを特徴とする。 The faucet device according to one embodiment comprises a faucet body, a water discharge head that is detachable from the faucet body, and a flexible resin hose section that is connected to the water discharge head so that water can pass through. The water discharge head comprises a head body having a water outlet, and a connecting section that is inserted into the hose section, and is characterized by having a reinforcing member attached to the end of the connecting section within the hose section.
これにより、吐水ヘッドが引き出されて使用される際に補強部材がホース部を内側から支持することで、ホース部の耐久性を確保することができる。また、吐水ヘッドが様々な方向に取り回されても、補強部材が曲がることで吐水ヘッドの取り回しがし易く、吐水ヘッドの操作性を確保することができる。したがって、吐水ヘッドを引き出して使用するときの樹脂製のホース部の耐久性の確保と吐水ヘッドの操作性との両立を実現することができる。 As a result, when the water spouting head is pulled out and used, the reinforcing member supports the hose portion from the inside, ensuring the durability of the hose portion. Furthermore, even if the water spouting head is rotated in various directions, the reinforcing member bends, making it easy to handle the water spouting head and ensuring operability of the water spouting head. Therefore, it is possible to ensure both the durability of the resin hose portion when the water spouting head is pulled out and used, and the operability of the water spouting head.
また、補強部材は、コイル部であることを特徴とする。 Furthermore, the reinforcing member is a coil portion.
これにより、簡易的な構成で吐水ヘッドを引き出して使用するときの樹脂製のホース部の耐久性の確保と吐水ヘッドの操作性との両立を実現することができる。 This allows for a simple configuration that ensures both the durability of the resin hose section when the water discharge head is pulled out for use, and the ease of use of the water discharge head.
また、前記接続部は、前記端部の外周面に螺旋溝を有することを特徴とする。 The connecting portion is also characterized by having a spiral groove on the outer peripheral surface of the end portion.
これにより、コイル部が接続部から外れにくくすることができる。 This makes it difficult for the coil part to come off the connection part.
また、前記コイル部は、少なくとも一部が前記接続部の端部に取り付けられる一端の第１部分と、前記第１部分よりも他端側に位置する第２部分と、を有し、前記第１部分の巻きピッチは、前記第２部分の巻きピッチよりも短いことを特徴とする。 Furthermore, the coil portion has a first portion at one end, at least a portion of which is attached to the end of the connection portion, and a second portion located closer to the other end than the first portion, and the winding pitch of the first portion is shorter than the winding pitch of the second portion.
これにより、巻きピッチの短い第１部分によってコイル部が接続部から外れにくくするとともに、巻きピッチが第１部分より長い第２部分によって吐水ヘッドの取り回しがし易くなる。 As a result, the first section, which has a shorter winding pitch, makes it less likely for the coil to come off the connection, while the second section, which has a longer winding pitch than the first section, makes it easier to handle the water discharge head.
本発明の態様によれば、吐水ヘッドを引き出して使用するときの樹脂製ホースの耐久性の確保と吐水ヘッドの操作性との両立を実現することができる。 This aspect of the present invention makes it possible to ensure both the durability of the resin hose when the water spout head is pulled out for use and the operability of the water spout head.
以下、実施形態について図面を参照しつつ説明する。なお、各図面中、同様の構成要素
には同一の符号を付して詳細な説明は適宜省略する。また、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。
Hereinafter, embodiments will be described with reference to the drawings. In each drawing, similar components are designated by the same reference numerals, and detailed descriptions thereof will be omitted as appropriate. Furthermore, the present invention is not limited to the embodiments described below.
実施形態に係る水栓装置１について、図１、２を参照し説明する。図１は、実施形態に係る水栓装置１の斜視図である。図２は、実施形態に係る水栓装置１のホース部３０が引き出された状態の断面図である。 The faucet device 1 according to the embodiment will be described with reference to Figures 1 and 2. Figure 1 is a perspective view of the faucet device 1 according to the embodiment. Figure 2 is a cross-sectional view of the faucet device 1 according to the embodiment with the hose portion 30 pulled out.
水栓装置１は、例えばキッチンや洗面化粧台等に備えられたカウンターＣに取り付けられるものであって、水栓本体１０と、水栓本体１０に対して着脱自在である吐水ヘッド２０と、吐水ヘッド２０に対して通水可能に接続された可撓性を有する樹脂製のホース部３０と、を備えている。 The faucet device 1 is attached to a counter C, such as that found in a kitchen or bathroom vanity, and comprises a faucet body 10, a water discharge head 20 that is detachable from the faucet body 10, and a flexible resin hose portion 30 that is connected to the water discharge head 20 to allow water to pass through.
水栓本体１０は、上部に備えられたレバー１１と、吐水ヘッド２０が着脱可能であり、吐水ヘッド２０の移動に伴ってホース部３０を引出・挿入可能なスパウト部１２と、を有する。 The faucet body 10 has a lever 11 attached to the top, a spout portion 12 to which the water discharge head 20 can be attached and detached, and the hose portion 30 can be inserted and withdrawn as the water discharge head 20 moves.
吐水ヘッド２０は、吐水口２１を有するヘッド本体２２と、一端がヘッド本体２２に接続され、他端がホース部３０に接続される継手管２３と、を備えている。継手管２３は、ヘッド本体２２とは別体で形成されている。スパウト部１２に装着された状態の吐水ヘッド２０をスパウト部１２から引き出すと、図２に示すように、ホース部３０も一緒に引き出される。これにより、吐水ヘッド２０がスパウト部１２に装着された状態では吐水口２１が届かない位置にも吐水を届かせることができ、広範囲への吐水が可能となる。 The water spout head 20 comprises a head body 22 having a water spout 21, and a coupling pipe 23, one end of which is connected to the head body 22 and the other end of which is connected to the hose section 30. The coupling pipe 23 is formed separately from the head body 22. When the water spout head 20 attached to the spout section 12 is pulled out from the spout section 12, the hose section 30 is also pulled out, as shown in Figure 2. This allows water to reach locations that the water spout 21 cannot reach when the water spout head 20 is attached to the spout section 12, enabling water to be sprayed over a wide area.
続いて、実施形態に係る水栓装置１の継手管２３とホース部３０との接続部分およびコイル部４０について、図３を参照し説明する。図３は、実施形態に係る水栓装置１の（Ａ）一部を模式的に表す拡大断面図、（Ｂ）継手管２３とコイル部４０の分解図である。 Next, the connection portion between the joint pipe 23 and the hose portion 30, and the coil portion 40 of the faucet device 1 according to the embodiment will be described with reference to Figure 3. Figure 3 shows (A) an enlarged cross-sectional view schematically illustrating a portion of the faucet device 1 according to the embodiment, and (B) an exploded view of the joint pipe 23 and the coil portion 40.
継手管２３は、ヘッド本体２２が接続される一端側のヘッド本体側接続部２４と、ホース部３０が接続される他端側のホース部側接続部２５と、を有する。 The joint pipe 23 has a head body side connection portion 24 at one end to which the head body 22 is connected, and a hose part side connection portion 25 at the other end to which the hose part 30 is connected.
ホース部側接続部２５は、ホース部３０内に挿入されている。ホース部側接続部２５の外周面には、ホース部３０の内面に食い込む環状突起２５ａと、ホース部３０の内面と対向して圧接する環状凹部２５ｂと、後述するコイル部４０が取り付けられる端部２５ｃと、が設けられている。 The hose-side connecting portion 25 is inserted into the hose portion 30. The outer surface of the hose-side connecting portion 25 is provided with an annular protrusion 25a that bites into the inner surface of the hose portion 30, an annular recess 25b that faces and presses against the inner surface of the hose portion 30, and an end portion 25c to which the coil portion 40 (described below) is attached.
端部２５ｃは、環状突起２５ａや環状凹部２５ｂが設けられた部分（いわゆる、端部２５ｃよりもヘッド本体２２側の部分）よりも外周径が小さくなるように形成されている。また、端部２５ｃの外周面には、螺旋溝２５ｄが形成されている。螺旋溝２５ｄの外周の径は、コイル部４０の内周部の径とほぼ同じ大きさになっている。好ましくは、螺旋溝２５ｄの外周の径とコイル部４０の内周部の径とが同じ大きさ、もしくは螺旋溝２５ｄの外周の径よりもコイル部４０の内周部の径が小さくなっている。 End 25c is formed so that its outer diameter is smaller than the portion where annular protrusion 25a and annular recess 25b are provided (i.e., the portion closer to head body 22 than end 25c). A spiral groove 25d is formed on the outer peripheral surface of end 25c. The outer diameter of spiral groove 25d is approximately the same as the diameter of the inner peripheral portion of coil portion 40. Preferably, the outer diameter of spiral groove 25d and the diameter of the inner peripheral portion of coil portion 40 are the same, or the diameter of the inner peripheral portion of coil portion 40 is smaller than the outer diameter of spiral groove 25d.
端部２５ｃとコイル部４０の接続方法について説明する。コイル部４０の内周部を端部２５ｃに合わせ、コイル部４０をコイル部４０の巻き方向に回しながら端部２５ｃへ押し込む。すると、コイル部４０の内周部に対して外径方向に力が加わり、コイル部４０の内周部の径が広がる。これにより、コイル部４０の内径が端部２５ｃの外径より大きくなり、コイル部４０は端部２５ｃに容易に取り付けられる。取付状態においてはコイル部４０と端部２５ｃの取付位置が固定された状態となっており、コイル部４０をコイル部４０の巻き方向とは反対方向に回すと、コイル部４０の内周部の径が小さくなる方向に力が加わるため、コイル部４０は端部２５ｃに食いつくようになる。コイル部４０と端部２５ｃの間に働く垂直抗力が増大し、両者間の静止摩擦力が増大する。結果として、コイル部４０の端部２５ｃに対する相対的な運動が抑制され、コイル部４０は端部２５ｃから外れにくくなっている。 The method for connecting the end 25c and the coil portion 40 will be described below. The inner periphery of the coil portion 40 is aligned with the end 25c, and the coil portion 40 is pressed into the end 25c while being rotated in the winding direction of the coil portion 40. This applies a force to the inner periphery of the coil portion 40 in the outward direction, expanding the diameter of the inner periphery of the coil portion 40. This makes the inner diameter of the coil portion 40 larger than the outer diameter of the end 25c, allowing the coil portion 40 to be easily attached to the end 25c. In the attached state, the attachment positions of the coil portion 40 and the end 25c are fixed. When the coil portion 40 is rotated in the opposite direction to the winding direction of the coil portion 40, a force is applied in a direction that reduces the diameter of the inner periphery of the coil portion 40, causing the coil portion 40 to bite into the end 25c. The normal force acting between the coil portion 40 and the end 25c increases, increasing the static friction between them. As a result, relative movement of the coil portion 40 with respect to the end portion 25c is suppressed, making it difficult for the coil portion 40 to come off the end portion 25c.
続いて、実施形態に係る水栓装置１のコイル部４０について、図３を参照し説明する。 Next, the coil portion 40 of the faucet device 1 according to this embodiment will be described with reference to Figure 3.
コイル部４０は、継手管２３とは別体で形成されたステンレス製の線材を螺旋状に巻いた部材である。コイル部４０は、少なくとも一部が端部２５ｃに取り付けられる一端の第１部分４１と、第１部分４１よりも他端側に位置する第２部分４２と、他端の第３部分４３と、を有する。 The coil portion 40 is a spirally wound stainless steel wire formed separately from the joint pipe 23. The coil portion 40 has a first portion 41 at one end, at least a portion of which is attached to the end portion 25c, a second portion 42 located closer to the other end than the first portion 41, and a third portion 43 at the other end.
第１部分４１、第２部分４２、第３部分４３はそれぞれ巻きピッチが異なる。巻きピッチとは、単位長さあたりの巻き数のことを指す。第１部分４１は、継手管２３とコイル部４０との接続部付近のホース部３０の耐久性を確保してキンクしにくくなるように、線材同士が接触するように密着させた巻きピッチにしている。また、第２部分４２は、吐水ヘッド２０の取り回しがし易いように線材同士の隙間が３～６ｍｍとなるような巻きピッチにしている。第３部分４３は、コイル部４０の端部がホース部３０に接触してもホース部３０を傷つけないように、第１部分４１と同様に線材同士が接触するように密着させた巻きピッチにしている。なお、第１部材４１の巻きピッチを端部２５ｃの螺旋溝２５ｄの巻きピッチよりも小さくする、もしくは同じにすることで、コイル部４０は端部２５ｃからより外れにくくなる。 The first portion 41, second portion 42, and third portion 43 each have a different winding pitch. The winding pitch refers to the number of windings per unit length. The first portion 41 has a winding pitch that ensures close contact between the wires, ensuring durability and reducing kinking of the hose portion 30 near the connection between the coupling pipe 23 and the coil portion 40. The second portion 42 has a winding pitch that leaves a gap of 3 to 6 mm between the wires, making it easier to handle the water discharge head 20. The third portion 43 has a winding pitch that ensures close contact between the wires, similar to the first portion 41, so that the hose portion 30 is not damaged even if the end of the coil portion 40 comes into contact with it. Note that by making the winding pitch of the first member 41 smaller than or equal to the winding pitch of the spiral groove 25d of the end portion 25c, the coil portion 40 is less likely to come off the end portion 25c.
実施形態に係る水栓装置１は、水栓本体１０と、水栓本体１０に対して着脱自在である吐水ヘッド２０と、吐水ヘッド２０に対して通水可能に接続されて可撓性を有する樹脂製のホース部３０と、を備えた水栓装置１であって、吐水ヘッド２０は、吐水口２１を有するヘッド本体２２と、ホース部３０内に挿入される接続部（ホース部側接続部２５）と、を備え、ホース部３０内において接続部（ホース部側接続部２５）の端部２５ｃに取り付けられるコイル部４０（補強部材）を有することを特徴とする。 The faucet device 1 according to this embodiment comprises a faucet body 10, a water discharge head 20 that is detachable from the faucet body 10, and a flexible resin hose section 30 that is connected to the water discharge head 20 and allows water to pass through. The water discharge head 20 comprises a head body 22 that has a water discharge outlet 21, and a connection section (hose section-side connection section 25) that is inserted into the hose section 30, and is characterized by having a coil section 40 (reinforcing member) that is attached to the end 25c of the connection section (hose section-side connection section 25) within the hose section 30.
これにより、吐水ヘッド２０が引き出されて使用される際にコイル部４０がホース部３０を内側から支持することで、ホース部３０の耐久性を確保することができる。また、吐水ヘッド２０が様々な方向に取り回されても、コイル部３０が曲がることで吐水ヘッド２０の取り回しがし易く、吐水ヘッド２０の操作性を確保することができる。したがって、吐水ヘッド２０を引き出して使用するときの樹脂製のホース部３０の耐久性の確保と吐水ヘッド２０の操作性との両立を実現することができる。 As a result, when the water spouting head 20 is pulled out and used, the coil portion 40 supports the hose portion 30 from the inside, ensuring the durability of the hose portion 30. Furthermore, even if the water spouting head 20 is handled in various directions, the coil portion 30 bends, making it easy to handle the water spouting head 20 and ensuring the operability of the water spouting head 20. Therefore, it is possible to ensure both the durability of the resin hose portion 30 when the water spouting head 20 is pulled out and used, and the operability of the water spouting head 20.
また、接続部（ホース部側接続部２５）は、端部２５ｃの外周面に螺旋溝２５ｄを有することを特徴とする。 The connection part (hose-side connection part 25) is also characterized by having a spiral groove 25d on the outer peripheral surface of the end part 25c.
これにより、コイル部４０が接続部（ホース部側接続部２５）から外れにくくすることができる。 This makes it difficult for the coil portion 40 to come off the connection portion (hose portion side connection portion 25).
また、コイル部４０は、少なくとも一部が接続部（ホース部側接続部２５）の端部２５ｃに取り付けられる一端の第１部分４１と、第１部分４１よりも他端側に位置する第２部分４２と、を有し、第１部分４１の巻きピッチは、第２部分４２の巻きピッチよりも短いことを特徴とする。 The coil portion 40 also has a first portion 41 at one end, at least a portion of which is attached to the end 25c of the connection portion (hose portion-side connection portion 25), and a second portion 42 located closer to the other end than the first portion 41, and the winding pitch of the first portion 41 is shorter than the winding pitch of the second portion 42.
これにより、巻きピッチの短い第１部分４１によってコイル部４０が接続部（ホース部側接続部２５）から外れにくくするとともに、巻きピッチが第１部分４１より長い第２部分４２によって吐水ヘッド２０の取り回しがし易くなる。 As a result, the first portion 41, which has a short winding pitch, makes it difficult for the coil portion 40 to come off the connection portion (hose portion side connection portion 25), while the second portion 42, which has a longer winding pitch than the first portion 41, makes it easier to handle the water discharge head 20.
本発明は上述した実施形態に限られない。例えば、上述した実施形態においては、継手管２３の端部２５ｃの外周面を螺旋溝２５ｄとしたが、これに限られない。図４に示すように、端部１２５ｃの外周面に凹部１２５ｄを設けた継手管１２３とし、コイル部４０の端部が凹部１２５ｄに嵌まり込むことでコイル部４０が継手管１２３の端部１２５ｃから外れにくくなるように構成してもよい。また、図５に示すように、端部２２５ｃの外周面に先端に向けて径が広がるように傾斜させたテーパ部２２５ｄを設けた継手管２２３とし、コイル部４０と継手管２２３の端部２２５ｃが接続された後にコイル部４０が継手管２２３の端部２２５ｃから外れにくくなるように構成してもよい。 The present invention is not limited to the above-described embodiment. For example, in the above-described embodiment, the outer peripheral surface of the end 25c of the coupling pipe 23 is formed with a spiral groove 25d, but this is not limited to this. As shown in FIG. 4, the coupling pipe 123 may be configured so that a recess 125d is provided on the outer peripheral surface of the end 125c, and the end of the coil portion 40 fits into the recess 125d, making it difficult for the coil portion 40 to come off the end 125c of the coupling pipe 123. Furthermore, as shown in FIG. 5, the coupling pipe 223 may be configured so that a tapered portion 225d is provided on the outer peripheral surface of the end 225c, which is inclined so that the diameter widens toward the tip, making it difficult for the coil portion 40 to come off the end 225c of the coupling pipe 223 after the coil portion 40 and the end 225c of the coupling pipe 223 are connected.
また、上述した実施形態においては、補強部材としてコイル部４０を採用したが、これに限らない。例えば、補強部材として可撓性のチューブやスパイラルチューブなどを採用し、ホース部３０内において接続部（ホース部側接続部２５）の端部２５ｃに取り付けてもよい。 In addition, while the above-described embodiment employs a coil portion 40 as a reinforcing member, this is not limited to this. For example, a flexible tube or spiral tube may be employed as the reinforcing member and attached to the end portion 25c of the connection portion (hose portion-side connection portion 25) within the hose portion 30.
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 their equivalents.
