従来のノズルの取付構造では、ノズル受部55を板金54に固定しており、そのため、ノズルカバー56は板金54により形状が制限されてしまうという問題点があり、また、板金54が必要であり、部材が多くなり、コストが増大してしまうという問題点があった。また、単に板金54無しでノズル受部55をノズルカバー56に支持させた場合は、ノズルキャップ53を外した場合に、配管が柔らかいホースであると、ノズル受部55がノズルカバー56内に脱落する虞れがあるという問題点があった。   In the conventional nozzle mounting structure, the nozzle receiving portion 55 is fixed to the sheet metal 54. Therefore, there is a problem that the shape of the nozzle cover 56 is limited by the sheet metal 54, and the sheet metal 54 is necessary. There is a problem that the number of members increases and the cost increases. Further, when the nozzle receiving portion 55 is simply supported by the nozzle cover 56 without the sheet metal 54, the nozzle receiving portion 55 falls into the nozzle cover 56 when the nozzle cap 53 is removed and the piping is a soft hose. There was a problem that there was a possibility of doing.

本発明は上記従来の問題点に鑑み案出したものであって、ノズルカバーの形状が制限されることなく、また板金が不要となって、部品点数を減少させることのできるノズル取付構造を提供せんとするものであり、請求項1は、ノズルカバーの開口に、内側より鍔付きのノズル受部を挿通させ、該ノズル受部に対しノズルを嵌めるとともに、前記ノズルカバーの外側より脱落防止部材を介在させてノズルキャップを締め付け、該ノズルキャップと前記ノズル受部の鍔間に前記ノズルカバーを挟み込んで固定するノズル取付構造において、前記ノズルカバーの開口の外側には、前記脱落防止部材が嵌め込まれる凹部が形成されていることである。
また、請求項は、前記ノズル受部の外周には、前記脱落防止部材が外嵌される凹部が形成されていることである。
The present invention has been devised in view of the above-mentioned conventional problems, and provides a nozzle mounting structure that can reduce the number of parts without limiting the shape of the nozzle cover and eliminating the need for sheet metal. According to a first aspect of the present invention, a nozzle receiving portion having a flange is inserted from the inside into the opening of the nozzle cover, the nozzle is fitted into the nozzle receiving portion, and a drop-off preventing member is provided from the outside of the nozzle cover. In the nozzle mounting structure in which the nozzle cap is tightened with the nozzle cap interposed therebetween and the nozzle cover is sandwiched and fixed between the nozzle cap and the nozzle receiving portion , the drop-off prevention member is fitted outside the opening of the nozzle cover. That is, a concave portion is formed .

In the nozzle mounting structure of the present invention, since the nozzle cover is sandwiched and fixed between the nozzle cap and the nozzle receiving portion, it is not necessary to use a sheet metal or a screw to fix the nozzle receiving portion. The number of points can be reduced and the cost can be reduced, and the nozzle cover is fixed by sandwiching the nozzle cover with the nozzle receiving part collar and the nozzle cap, so the nozzle can be fixed according to the shape of the nozzle cover, The shape of the nozzle cover is not limited. In addition, the drop-out prevention member prevents the nozzle receiving part from dropping into the nozzle cover even when the nozzle cap is removed, and the drop-out prevention member can position the nozzle receiving part to prevent displacement. Will be able to.
In addition, the drop-off prevention member can be concealed in the concave portion outside the opening of the nozzle cover, the nozzle cap does not float up, it is difficult to form a gap between the nozzle cap and the nozzle cover, and dirt is accumulated well. It can be prevented.

また、ノズル受部の外周には、脱落防止部材が外嵌される凹部が形成されていることにより、ノズル受部の凹部内に脱落防止部材が嵌め込まれて、ノズルキャップを外した状態で、ノズル受部がノズルカバーの内側に脱落するのを良好に防ぐことができるものとなる。   Further, the outer periphery of the nozzle receiving part is formed with a recess into which the drop-off preventing member is fitted, so that the drop-off preventing member is fitted into the recess of the nozzle receiving part and the nozzle cap is removed, It is possible to satisfactorily prevent the nozzle receiving portion from falling off inside the nozzle cover.

以下、本発明の実施例を図面に基づいて説明する。
図1は、浴室の壁面に設置されるシャワー装置の斜視構成図である。
シャワー装置1は、左右のアーム3,3で構成される上側散水部5と、上側散水部5の下端よりも下方に延びる左右一対の下側散水部6で構成されており、上側散水部5及び下側散水部6には、それぞれ複数の散水ノズル4,4,4が設けられている。
Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a perspective configuration diagram of a shower device installed on a wall surface of a bathroom.
The shower device 1 includes an upper watering portion 5 composed of left and right arms 3 and 3 and a pair of left and right lower watering portions 6 extending downward from the lower end of the upper watering portion 5. The lower watering part 6 is provided with a plurality of watering nozzles 4, 4, 4, respectively.

図2は、浴室の壁面Wにシャワー装置1を設置した状態の側面構成図であり、上側散水部5を構成するアーム3は、下方へ回動させて使用することができるものとなっており、一方の下側散水部6は、壁面Wに固定されたものとなっている。
下側散水部6を構成するノズルカバー8の前面に取り付けられるノズル4の構成部材の分解拡大斜視図を図3に示し、また、図4では、ノズル4の取付状態の断面拡大図を示す。
FIG. 2 is a side configuration diagram of the state in which the shower device 1 is installed on the wall surface W of the bathroom, and the arm 3 constituting the upper watering portion 5 can be used by rotating downward. The one lower water sprinkling part 6 is fixed to the wall surface W.
FIG. 3 shows an exploded enlarged perspective view of the constituent members of the nozzle 4 attached to the front surface of the nozzle cover 8 constituting the lower water sprinkling portion 6, and FIG. 4 shows an enlarged sectional view of the nozzle 4 attached.

ノズルカバー8には、貫通状に開口8aが形成されており、この開口8aの前面側には、外側から内側へ向かって凹んだ凹部8bが開口8aの外周に形成されている。また、開口8aの裏側には、内側へ突出したストッパー8c,8cが、例えば2個程度設けられている。
このノズルカバー8の開口8aの内側に配置されるノズル受部9は、前面側に半球状の凹部9aが形成された筒状をなし、奥側外周には間隔をおいて複数の鍔9c,9cが外側へ向かって突出形成され、鍔9cの前側外周には、凹み状に凹部9bが形成されており、鍔9cの後方には、同軸状に後方側へ延びて配管接続部9dが形成され、この配管接続部9dに、例えばホースなどで構成される配管13が接続されるものである。
An opening 8a is formed in the nozzle cover 8 in a penetrating manner, and a recess 8b that is recessed from the outside to the inside is formed on the outer periphery of the opening 8a on the front side of the opening 8a. Further, on the back side of the opening 8a, for example, about two stoppers 8c, 8c projecting inward are provided.
The nozzle receiving portion 9 arranged inside the opening 8a of the nozzle cover 8 has a cylindrical shape in which a hemispherical concave portion 9a is formed on the front side, and a plurality of flanges 9c, 9c is formed to protrude outward, and a recess 9b is formed in a concave shape on the front outer periphery of the flange 9c, and a pipe connection portion 9d is formed on the rear side of the flange 9c so as to extend coaxially to the rear side. Then, a pipe 13 composed of, for example, a hose is connected to the pipe connecting portion 9d.

一方、ノズルカバー8の開口8aの外側からは、オーリング10で構成される脱落防止部材が凹部8b内に嵌め込まれるものであり、また、球部4aと噴出部4bで構成されるノズル4が外側からノズル受部9の球状凹部9a内に嵌め込まれるものである。
さらにノズル4には止水用オーリング11を介在させてノズルキャップ12が嵌め込まれ、このノズルキャップ12の内周に形成された雌ネジを、ノズル受部9の外周の雄ネジに締め付けることにより、ノズルキャップ12とノズル受部9の鍔9c間にノズルカバー8を挟み込んだ状態でノズル4を固定できるように構成されている。
On the other hand, from the outside of the opening 8a of the nozzle cover 8, a drop-off prevention member constituted by the O-ring 10 is fitted into the recess 8b, and the nozzle 4 constituted by the spherical portion 4a and the ejection portion 4b is provided. It is fitted into the spherical recess 9a of the nozzle receiving portion 9 from the outside.
Further, a nozzle cap 12 is fitted into the nozzle 4 with a water stop O-ring 11 interposed therebetween, and a female screw formed on the inner periphery of the nozzle cap 12 is fastened to a male screw on the outer periphery of the nozzle receiving portion 9. The nozzle 4 can be fixed in a state where the nozzle cover 8 is sandwiched between the nozzle cap 12 and the flange 9c of the nozzle receiving portion 9.

なお、開口8a内に内側より挿通されるノズル受部9に対し、外側からノズルキャップ12を締め付ける際に、予めノズルカバー8の外側よりオーリング10を凹部8b内に嵌め込み、しかも、このオーリング10をノズル受部9の凹部9b内に嵌め込んでおくことにより、ノズル受部9をノズルカバー8に位置決めして仮固定しておくことができ、この状態では、ノズル受部9はノズルカバー8の内側へ脱落することがなく、良好に位置決めされるものとなる。   When the nozzle cap 12 is tightened from the outside with respect to the nozzle receiving portion 9 inserted from the inside into the opening 8a, the O-ring 10 is fitted in the recess 8b from the outside of the nozzle cover 8 in advance. 10 is fitted into the recess 9b of the nozzle receiving portion 9, so that the nozzle receiving portion 9 can be positioned and temporarily fixed to the nozzle cover 8, and in this state, the nozzle receiving portion 9 is in the nozzle cover. It will be positioned well without falling off inside 8.

また、鍔部9c,9c間にストッパー8c,8cが嵌まり込んだ状態では、外側よりノズルキャップ12をノズル受部9に締め付けても、ノズル受部9が空回りすることはなく、良好に外側よりノズルキャップ12を締め付けてゆくことができるものである。
また、オーリング10は凹部8b内に嵌め込まれているため、ノズルキャップ12がノズルカバー8の外側に浮き上がることがなく、ノズルキャップ12とノズルカバー8間に隙間ができにくく、締め付けた状態の見栄えが良好で、ノズルキャップ12の後端はほぼ開口8aの外周に当接状態となり、この部分に汚れが溜まることがない。
Further, in a state in which the stoppers 8c and 8c are fitted between the flange portions 9c and 9c, even if the nozzle cap 12 is fastened to the nozzle receiving portion 9 from the outside, the nozzle receiving portion 9 does not rotate freely, and the outer side is satisfactorily The nozzle cap 12 can be further tightened.
Further, since the O-ring 10 is fitted in the recess 8b, the nozzle cap 12 does not float outside the nozzle cover 8, and it is difficult to form a gap between the nozzle cap 12 and the nozzle cover 8. The rear end of the nozzle cap 12 is almost in contact with the outer periphery of the opening 8a, and no dirt accumulates in this portion.

このようにしてノズルキャップ12をノズル受部9に締め付けてゆくことで、ノズルキャップ12とノズル受部9の鍔9c間にノズルカバー8を挟み込んで固定できるため、従来のような板金は必要とせず、良好にノズル受部9をノズルカバー8に固定することができ、部品点数が従来よりも少なくなり、また、ノズルカバー8の形状は制限されることがなく、ノズルカバー8の形状に合わせて開口8aに良好にノズル受部9を固定し、ノズル4を取り付けることができるものとなる。   By tightening the nozzle cap 12 to the nozzle receiving portion 9 in this way, the nozzle cover 8 can be sandwiched and fixed between the nozzle cap 12 and the flange 9c of the nozzle receiving portion 9, so that a conventional sheet metal is not required. Therefore, the nozzle receiving part 9 can be fixed to the nozzle cover 8 well, the number of parts is smaller than that of the conventional one, and the shape of the nozzle cover 8 is not limited. Thus, the nozzle receiving portion 9 can be satisfactorily fixed to the opening 8a and the nozzle 4 can be attached.

また、メンテナンス時等にノズルキャップ12を外した状態でも、オーリング10が凹部8b及び凹部9b内に嵌まり込んでいるため、外側からノズル受部9を押圧しても、内側へノズル受部9が脱落することが防がれ、配管13が柔らかいホースで構成されている場合でも、ノズル受部9の内側への脱落が防がれるものとなる。   Even when the nozzle cap 12 is removed during maintenance or the like, since the O-ring 10 is fitted in the recess 8b and the recess 9b, the nozzle receiver can be moved inward even if the nozzle receiver 9 is pressed from the outside. 9 is prevented from falling off, and even when the pipe 13 is formed of a soft hose, it is possible to prevent the nozzle receiving portion 9 from falling out.
