本発明はシャワーヘッドの支持装置に関する。 The present invention relates to a showerhead support device.
近年、湯水等の水栓の本体にホース等の可撓管を用いて接続されたシャワーヘッドを備えた洗面台や流し台等が広く用いられている。そして、この種の洗面台等においては、シャワーヘッドの後端部を、この可撓管が挿通された状態で抜き差し自在に収容支持する支持装置が用いられることが多い。このような支持装置では筒状に突出する収容支持部と、この収容支持部に装着固定される中空状の支承部材とを備え、シャワーヘッドの後端部は、この支承部材内に収容支持されるのが一般的である。その際、シャワーヘッドの後端部と、支承部材とはセレーションを用いた噛合や、スライド突起とスライド溝との係合等の手法により連結され、この結果、シャワーヘッド全体が支承部材、ひいては、収容支持部に回動不能な状態に支持されることが多い。 In recent years, a wash basin or a sink equipped with a shower head connected to a main body of a faucet such as hot water using a flexible tube such as a hose has been widely used. And in this kind of washstand etc., the support apparatus which accommodates and supports the rear-end part of a shower head detachably in the state by which this flexible tube was penetrated is used in many cases. Such a support device includes a housing support portion that protrudes in a cylindrical shape and a hollow support member that is mounted and fixed to the housing support portion, and the rear end portion of the shower head is housed and supported in the support member. It is common. At that time, the rear end portion of the shower head and the support member are connected by a method such as meshing using serrations, engagement of the slide protrusion and the slide groove, and as a result, the entire shower head is supported by the support member, In many cases, the accommodation support part is supported in a non-rotatable state.
一方、このような収容支持部への支承部材の固定には、ネジ止め、ビス止めをする手段の他に、支承部材から突設した係合突起を、収容支持部の係合用透孔に係合させて行うものが知られている。このような係合手段を用いた支持装置は、ネジ止め、ビス止めと比較して、部品点数の削減・ネジ孔やビス孔周辺の応力割れを低減させるメリットがある(特許文献1参照)。 On the other hand, in order to fix the support member to such a housing support portion, in addition to means for screwing and screwing, an engagement protrusion protruding from the support member is engaged with the engagement through hole of the storage support portion. What is done in combination is known. A support device using such an engaging means has advantages of reducing the number of parts and reducing stress cracking around screw holes and screw holes compared to screwing and screwing (see Patent Document 1).
しかしながら、前述した従来のシャワーヘッドの支持装置では、収容支持部から支承部材を強く引き抜くような力が加わった場合に、合成樹脂製とされるような係合突起が撓み、その結果、係合用透孔から係合突起が外れ、収容支持部から支承部材が抜け落ちてしまうなど十分な固定ができない可能性があった。 However, in the above-described conventional showerhead support device, when a force that strongly pulls out the support member from the housing support portion is applied, the engagement protrusions made of synthetic resin bend, and as a result, There is a possibility that sufficient engagement cannot be achieved, for example, the engagement protrusion comes off from the through hole and the support member falls off from the housing support part.
本発明は前述した従来技術の問題点を解決しようとするものであり、係合用透孔から係合突起が容易には外れないようにして、収容支持部へ支承部材をより確実に固定するシャワーヘッドの支持装置を提供することを目的とする。 The present invention is intended to solve the above-mentioned problems of the prior art, and a shower that more securely fixes a support member to an accommodation support portion so that an engagement protrusion is not easily detached from an engagement through hole. It is an object of the present invention to provide a head support device.
以上の課題を解決するために、本発明の採った手段を以下に説明する。本発明の第一の手段のシャワーヘッドの支持装置は、筒状に突出する収容支持部を有する支持装置本体と、前記収容支持部の内部に装着された中空状の支承部材とを備え、前記収容支持部には係合用透孔が穿設され、前記支承部材には係合突起を備え、係合突起が係合用透孔に係合されることにより支承部材は収容支持部に固定され、可撓管に接続されたシャワーヘッドの基端部分を、可撓管が前記支承部材に挿通された状態で、抜き差し自在に収容するシャワーヘッドの支持装置であって、前記係合用透孔は内周面に、その先端の縦断面形状が突状の被掛り突片を備え、前記係合突起は支承部材から突設された梁状部に設けられ、前記被掛り突片に当接可能であり、その先端が被掛り突片を乗り越える位置において、その角度が前記支承部材の先端方向に対して90°未満とされる掛り面を備えたことを特徴とするものである。 In order to solve the above problems, means taken by the present invention will be described below. According to a first aspect of the present invention, there is provided a showerhead support device including a support device body having a storage support portion protruding in a cylindrical shape, and a hollow support member mounted inside the storage support portion, The accommodation support part is provided with an engagement through hole, the support member is provided with an engagement projection, and the engagement projection is engaged with the engagement through hole, whereby the support member is fixed to the accommodation support part, A shower head support device that detachably accommodates a proximal end portion of a shower head connected to a flexible tube in a state in which the flexible tube is inserted through the support member, wherein the engaging through hole is an inner portion. The peripheral surface is provided with a hooked projecting piece having a longitudinal cross-sectional shape at the tip thereof, and the engaging protrusion is provided on a beam-like portion projecting from a support member, and can be brought into contact with the covered projecting piece. There is a position where the tip of the support part It is characterized in that it comprises a latching surface that is less than 90 ° to the distal direction.
本発明のシャワーヘッドの支持装置では、支承部材の係合突起の掛り面は、収容支持部の係合用透孔内の被掛り突片に係合されて、支承部材が収容支持部に対して固定される。この状態において、収容支持部から支承部材を引き抜くような力が加わった場合には、支承部材から突設された梁状部は、係合突起の掛り面が大きくなるように撓もうとするが、掛り面の先端が被掛り突片を乗り越える位置においても、その角度が90°未満となるように掛り面の角度があらかじめ定められている。よって、前述のようにして係合突起が撓もうとしても、係合される被掛り突片を介して掛り面に加わる力は、掛り面の前述した角度が小さくなる方向に働く。よって、前述した掛り面の角度は90°以上に大きくはならない。したがって、係合突起が破断するような状態に至るまでは、被掛り突片と掛り面との係合状態が解除されることは無い。 In the showerhead support device of the present invention, the hooking surface of the engaging protrusion of the support member is engaged with the hooked protrusion in the engaging through hole of the storage support portion, and the support member is in contact with the storage support portion. Fixed. In this state, when a force that pulls out the support member from the housing support portion is applied, the beam-like portion protruding from the support member tends to bend so that the hooking surface of the engagement protrusion becomes large. The angle of the hooking surface is determined in advance so that the angle is less than 90 ° even at the position where the tip of the hooking surface gets over the hooked protrusion. Therefore, even if the engaging protrusion is bent as described above, the force applied to the hooking surface via the hooked protrusion piece to be engaged acts in the direction in which the angle of the hooking surface decreases. Therefore, the angle of the above-described hanging surface does not increase to 90 ° or more. Therefore, the engagement state between the hooked protrusion piece and the hooking surface is not released until the engagement protrusion is broken.
また、本発明の第二の手段のシャワーヘッドの支持装置は、前記係合用透孔の被掛り突片に、前記係合突起の掛り面と面接触する傾斜面を備えたことを特徴とするものである。 The showerhead support device according to the second means of the present invention is characterized in that the hooked protrusion of the engagement through hole is provided with an inclined surface in surface contact with the hooking surface of the engagement protrusion.

係合用透孔の被掛り突片に、係合突起の掛り面と面接触する傾斜面を備えることにより、被掛り突片と掛り面とを安定して係合させることができる。よって、収容支持部から支承部材を引き抜くような力が加えられていない状態も含めて、被掛り突片と掛り面とが安定的に係合される。よって、支持装置に振動などが加えられた場合でも、被掛り突片と掛り面とが振動したり接触音を生ずるようなおそれを低減することができる。 By providing the hooked protrusion of the engagement through hole with an inclined surface in surface contact with the hooking surface of the engaging protrusion, the hooked protrusion and the hooking surface can be stably engaged. Therefore, the hooked projecting piece and the hooking surface are stably engaged with each other, including a state where no force is applied to pull out the support member from the housing support part. Therefore, even when vibration or the like is applied to the support device, it is possible to reduce the possibility that the hooked projecting piece and the hooking surface vibrate or cause contact noise.
また、本発明の第三の手段のシャワーヘッドの支持装置は、前記係合突起の掛り面および前記係合用透孔の被掛り突片の底面視形状が四角形状であることを特徴とするものである。 The showerhead support device according to the third means of the present invention is characterized in that the shape of the hooking surface of the engagement protrusion and the shape of the hooking protrusion of the engagement through hole in a bottom view are rectangular. It is.
掛り面および被掛り突片の底面視形状を四角形状とすることにより、底面視形状を三角形状などの突起状とした場合などに比べて、両部位が係合される部位を幅広くすることができる。よって、係合突起と係合用透孔をより安定的に係合させることができる。 By making the shape of the bottom surface of the hanging surface and the hooked projection piece a quadrilateral shape, it is possible to widen the portion where both portions are engaged compared to the case where the shape of the bottom surface view is a protrusion such as a triangle. it can. Therefore, the engagement protrusion and the engagement through hole can be more stably engaged.
また、本発明の第四の手段のシャワーヘッドの支持装置は、前記梁状部を、前記支承部材の軸心に対してその径方向外側に傾けて突設し、係合突起が係合用透孔への差込方向に弾性的に付勢されるようにしたことを特徴とするものである。 According to a fourth aspect of the present invention, there is provided a showerhead support device, wherein the beam-shaped portion is provided so as to be inclined outwardly in the radial direction with respect to the shaft center of the support member, and the engagement projection is engaged through. It is characterized by being elastically biased in the insertion direction into the hole.
このように係合突起が設けられる梁状部をあらかじめ傾けて突設しておくことにより、係合用透孔に係合された状態では係合突起が係合用透孔への差込方向に付勢されるようにしておくことができる。よって、より一層、係合用透孔から係合突起が外れ難くすることができる。 By projecting the beam-like portion provided with the engagement protrusion in advance in this manner, the engagement protrusion is attached in the insertion direction to the engagement through-hole when engaged with the engagement through-hole. It can be kept in force. Therefore, the engagement protrusion can be further prevented from coming off from the engagement through hole.
また、本発明の第五の手段のシャワーヘッドの支持装置は、前記係合用透孔は、係合突起が係合された状態で、水が流通可能な排水用の隙間を設けたことを特徴とするものである。 The showerhead support device according to the fifth means of the present invention is characterized in that the engaging through hole is provided with a drainage gap through which water can flow with the engaging projection engaged.

支承部材に挿通された可撓管には、シャワーヘッドを抜き差しする際に湯水が付着し、支持装置内にこの湯水が浸入するため、支持装置本体には、この湯水を支持装置本体の外部に排出するための水抜き孔を設ける必要がある。本発明のように係合用透孔は、係合突起が係合された状態で、水が流通可能な排水用の隙間を設けることにより、このような水抜き孔を係合用透孔の他に設ける必要を無くすことができる。 When the shower head is inserted and removed, hot water adheres to the flexible tube inserted through the support member, and this hot water enters the support device. Therefore, this hot water is placed outside the support device main body. It is necessary to provide a drain hole for discharging. As in the present invention, the engagement through hole is provided with a gap for drainage through which water can flow in a state in which the engagement protrusion is engaged. The necessity to provide can be eliminated.
本発明のシャワーヘッドの支持装置は前述のように構成されているので、係合用透孔から係合突起が容易には外れないようにして、収容支持部へ支承部材をより確実に固定することができる。 Since the shower head support device of the present invention is configured as described above, the support member can be more securely fixed to the housing support portion so that the engagement protrusion is not easily detached from the engagement through hole.

At this time, the engagement protrusion 38 provided on the support member 30 is positioned on the lower side. Next, as shown in FIG. 8, the support member 30 is inserted into the housing support portion 11 while the beam-like portion 36 is bent inward in the radial direction of the support member 30. As shown in FIG. 9, when the engaging protrusion 38 reaches the engaging through hole 16, the beam-like portion 36 starts to be restored. Then, as shown in FIG. 5, the engaging protrusion 38 is inserted into the engaging through hole 16 and engaged therewith, and this mounting is completed. In this mounted state, the axes of the accommodation support portion 11 and the support member 30 are configured to coincide, that is, to be parallel.
次に本支持装置Xの作用を説明する。図5に示されるように、支承部材30の係合突起38が収容支持部11の係合用透孔16に係合された通常の状態では、係合突起38の掛り面54と被掛り突片20の傾斜面24とが面接触されており、両部材間には隙間が無く、振動したり接触音を生ずるようなおそれを低減することができる。 Next, the operation of the support device X will be described. As shown in FIG. 5, in a normal state where the engaging protrusion 38 of the support member 30 is engaged with the engaging through hole 16 of the housing support portion 11, the hooking surface 54 and the hooking protrusion piece of the engaging protrusion 38 are provided. Twenty inclined surfaces 24 are in surface contact with each other, and there is no gap between the two members, so that it is possible to reduce the possibility of vibration or contact noise.
一方、収容支持部11から支承部材30を引き抜くような力が加わった場合には、図10に示されるように梁状部36が撓み、その先端が支承部材30の軸心に近づくように変形しようとする。この際に、前述のように角度を付けられた掛り面54は、その先端が被掛り突片20の先端を乗り越えるように変形される状態、すなわち係合突起38が係合用透孔16から外れる際の状態においても、収容支持部11および支承部材30の軸心先端方向から90°以上となることはない。よって、支承部材30を引き抜くような力が加わった場合に、梁状部36が撓んだとしても、係合される被掛り突片20を介して掛り面54に加わる力は、掛り面54の角度が小さくなろうとする方向に働くので、前述した掛り面の角度は90°以上に大きくはならない。したがって、梁状部36などが破断するような状態に至るまで、被掛り突片20と掛り面54との係合状態が解除されることは無い。このようにして、収容支持部11からの支承部材30の抜け落ちをより確実に防止することができる。 On the other hand, when a force that pulls out the support member 30 from the accommodating support portion 11 is applied, the beam-like portion 36 bends as shown in FIG. 10, and the tip thereof is deformed so as to approach the axis of the support member 30. try to. At this time, the hooking surface 54 that is angled as described above is deformed so that the tip of the hooking surface 54 gets over the tip of the hooking projection piece 20, that is, the engaging protrusion 38 is detached from the engaging through hole 16. Even in this state, it does not become 90 degrees or more from the axial center tip direction of the housing support part 11 and the support member 30. Therefore, when a force that pulls out the support member 30 is applied, even if the beam-like portion 36 bends, the force applied to the hanging surface 54 via the hooked protrusion 20 to be engaged is Therefore, the above-mentioned angle of the hanging surface does not become larger than 90 °. Therefore, the engaged state between the hooked protrusion 20 and the hooking surface 54 is not released until the beam-like portion 36 is broken. In this way, it is possible to more reliably prevent the support member 30 from coming off from the housing support portion 11.
本発明の実施の形態は前述のように構成されているが、本発明はこの実施の形態に限られるものではなく、本発明の主旨の範囲内で種々の変更が可能である。以下の例において第1の実施の形態と共通する構成については、第1の実施の形態と同一の符号を図面に付して説明を省略する。図11に示す第2の実施の形態の支持装置Xaは、収容支持部11の被掛り突片20aの形状が第1の実施の形態と異なるものである。この支持装置Xaの被掛り突片20aは、前述した第1の実施の形態の被掛り突片20よりもさらに鋭角的な縦断面形状をしている。このため、被掛り突片20a下部の傾斜面24aの基端寄りと係合突起38の掛り面54の先端寄りとの間に、所定角度の隙間が生ずることになり傾斜面24aと掛り面54とは面接触するものではない。しかしながら前述した第1の実施の形態と同様に、掛り面54の先端が被掛り突片20aの先端を乗り越えるように梁状部36が撓んだとしても、被掛り突片20aに係合されている掛り面54の角度によって、係合される被掛り突片20aを介して掛り面54に加わる力は、掛り面54の角度が小さくなる方向に働くことは同様であり、よって、前述した掛り面の角度は90°以上に大きくはならない。したがって、梁状部36などが破断するような状態に至るまで、被掛り突片20aと掛り面54との係合状態が解除されることは無い。 The embodiment of the present invention is configured as described above, but the present invention is not limited to this embodiment, and various modifications are possible within the scope of the gist of the present invention. In the following examples, the same reference numerals as those of the first embodiment are attached to the drawings for the configurations common to those of the first embodiment, and the description thereof is omitted. The support device Xa according to the second embodiment shown in FIG. 11 is different from the first embodiment in the shape of the hooked projection piece 20a of the housing support portion 11. The hanging protrusion 20a of the support device Xa has a sharper vertical cross-sectional shape than the hanging protrusion 20 of the first embodiment described above. For this reason, a gap of a predetermined angle is generated between the base end of the inclined surface 24a below the hooked protrusion 20a and the tip of the hooking surface 54 of the engaging projection 38, and the inclined surface 24a and the hooking surface 54 are formed. Is not in surface contact. However, as in the first embodiment described above, even if the beam-like portion 36 is bent so that the tip of the hooking surface 54 gets over the tip of the hooking protrusion 20a, it is engaged with the hooking protrusion 20a. The force applied to the hooking surface 54 via the hooked projecting piece 20a to be engaged according to the angle of the hooking surface 54 is the same as the action of the force of the hooking surface 54 in the direction of decreasing the angle. The angle of the hanging surface should not be greater than 90 °. Therefore, until the beam-like portion 36 or the like is broken, the engaged state between the hooked protrusion 20a and the hooking surface 54 is not released.
図12に示される第3の実施の形態の支持装置Xbは、梁状部36bを、支承部材30の軸心方向に対して、その径方向外側に傾けて突設したものである。このように梁状部36をあらかじめ傾けて突設しておくことにより、係合突起38が係合用透孔16に係合された状態において、係合突起38が係合用透孔16への差込方向に弾性的に付勢されるように設けることができ、収容支持部11からの支承部材30の抜け落ちをより一層確実に防止することができる。 The support device Xb according to the third embodiment shown in FIG. 12 has a beam-like portion 36 b that is inclined and protrudes radially outward with respect to the axial center direction of the support member 30. Thus, by projecting the beam-like portion 36 by inclining in advance, in the state where the engaging protrusion 38 is engaged with the engaging through hole 16, the engaging protrusion 38 is different from the engaging through hole 16. It can be provided so as to be elastically biased in the insertion direction, and the falling off of the support member 30 from the housing support portion 11 can be further reliably prevented.
図13に示される第4の実施の形態の支持装置Xcは、被掛り突片20cの上部に傾斜面24cを設け、下部に、収容支持部11の軸心と平行な延設面22cを設けている。一方、梁状部36の先端から下方に向けて傾斜面24cと同じ角度の傾斜部60を延設し、さらにこの傾斜部60の先端から折り返すように、延設面22cと面接触する掛り面54cを備えた掛り部52cを設けている。また、本実施の形態においては、係合用透孔16cに係合突起38cが係合された状態において、収容支持部11の後端側に排水用の隙間70が生ずるように設けられている。このような隙間70を設けることにより、前述した実施の形態のように水抜き孔14を設ける必要が無いので、孔の数を減らすことによる製造コストの低減や支持装置Xcの美観の向上を実現することができる。 The support device Xc of the fourth embodiment shown in FIG. 13 is provided with an inclined surface 24c at the upper part of the hooked protrusion piece 20c and an extended surface 22c parallel to the axis of the housing support part 11 at the lower part. ing. On the other hand, a sloping portion 60 having the same angle as that of the sloping surface 24c extends downward from the tip of the beam-like portion 36, and the hooking surface is in surface contact with the extending surface 22c so as to be folded back from the tip of the sloping portion 60 A hanging portion 52c provided with 54c is provided. Further, in the present embodiment, the drainage gap 70 is provided on the rear end side of the accommodation support portion 11 in a state where the engagement projection 38c is engaged with the engagement through hole 16c. By providing such a gap 70, it is not necessary to provide the drain holes 14 as in the above-described embodiment, so that the manufacturing cost can be reduced and the aesthetics of the support device Xc can be improved by reducing the number of holes. can do.
また、これらの実施の形態とは異なる参考例である第5の実施の形態として、例えば図14に示される支持装置Xdのように、係合突起38の掛り面54dおよびこれが係合する係合用透孔16dの内周面80に細かな凹凸82をそれぞれ形成し、係合突起38が係合用透孔16dから容易に抜けないように構成することができる。また、同様に、参考例である第6および第7の実施の形態として、図15に示される支持装置Xeのように、係合突起38の表面に縦断面三角形の突起84を突設し、一方、係合用透孔16の内周面にこれと嵌合可能な縦断面三角形の凹部86を形成することにより、係合突起38の掛り面54が係合用透孔16から容易に抜けないように構成することができる。また、図16に示される支持装置Xfのように、係合突起38の表面に縦断面四角形の突起85を突設し、一方、係合用透孔16の内周面にこれと嵌合可能な縦断面四角形の凹部87を形成することにより、係合突起38の掛り面54が係合用透孔16から容易に抜けないように構成することができる。なお、これらの図15および図16の例においては、突起84または突起85を係合用透孔16側に設け、凹部86または凹部87を係合突起38側に設けるように変更することも可能である。 Further, as a fifth embodiment which is a reference example different from these embodiments, for example, as in the support device Xd shown in FIG. 14, the hooking surface 54d of the engaging protrusion 38 and the engaging surface with which it engages. Fine irregularities 82 can be formed on the inner peripheral surface 80 of the through-hole 16d, respectively, so that the engaging projections 38 cannot be easily removed from the engaging through-hole 16d.
