Description

【０００１】
【発明の属する技術分野】
本発明は蛇口、分岐栓、切替弁、シャワーヘッド、浄水器等の流体の吐出口に装着してその乱流を整える泡沫網に関する。
【０００２】
【従来の技術】
従来、水道管の先端に蛇口が取り付けられて使用されている。しかし、蛇口からストレートに水を出すと、管内を流れる水は中心が速く、周囲が遅い乱流となっているため、吐出口から出る水が広がって飛沫になって飛び散り易い。そこで、図８に示すように蛇口１０の吐出口近傍の内部水路に、整流機構として泡沫網１２と水切り板１４とを装着して乱流を整えている。その際、泡沫網１２により水に抵抗を与えると、水の中に空気を混入し、泡沫を形成して乱流を整流化できる。又、水切り板１４を吐出口側に設置すると、更に水流を整流化できる。しかも、水切り板１４の周辺部分から泡沫網１２に空気を送ることができる。なお、１６が水道管との接続部、１８が操作用のハンドルである。
【０００３】
このような泡沫網として、通常は無数の格子目を有する１枚の網から吐出口内部の水路径にほぼ一致する外径を有する独立した単位網をそれぞれ打ち抜いて形成し、その独立した単位網を複数枚重ね合わせて使用している。しかし、独立した単位網を複数枚重ね合わせるだけでは重なり合う格子の目が偶然に一致して整流効果が大きく損なわれることがある。そこで、重なり合う格子目を一致させないようにするため、重なり合う格子目が互いに斜めに交差するように、単位網を互いにずらせて重ね合わせた後にスポット溶接する方法やインサート成形する方法等が行なわれている。なお、単位網には金属網、プラスチック網等が採用されている。
【０００４】
【発明が解決しようとする課題】
しかしながら、このようにして泡沫網を製作すると、単位網毎に打ち抜きを行なわなければならないため、打ち抜き工程が多く、取り扱いの数量も多くなって組み込み時に枚数を間違い易くなる。又、重なり合う格子目が互いにずれて斜めに交差するように、単位網を互いにずらせて重ね合わせるという工程を踏むと、当然工程数も増加してコスト高となる。
【０００５】
本発明はこのような従来の問題点に着目してなされたものであり、第１に工程数の省力化と取り扱いの簡易化を達成できると共に、組み込み枚数を間違えることがなく、重ね合わせる単位網の重なり合う格子目を簡単、確実に互いにずらして斜めに交差させることのできる安価な泡沫網を提供することを目的とする。
又、第２に優れた整流効果が得られる泡沫網を提供することを目的とする。
【０００６】
【課題を解決するための手段】
上記目的を達成するために、本発明による第１目的対応の泡沫網では無数の格子目を有する１枚の網から複数枚の単位網とその隣接する単位網間を結合する結合部とからなる連続した基材を打ち抜く際、その重ね合わさる単位網の重なり合う格子目が互いにずれて斜めに交差するように単位網間の相互位置を選択して打ち抜き、その連続基材を結合部で折り曲げて、それ等の単位網を重ね合わせる。又、第２目的対応の泡沫網では重ね合わせた単位網の重なり合う格子目が互いに等分にずれて斜めに交差する。
【０００７】
【発明の実施の形態】
以下、添付図面に基づいて、本発明の実施の形態を説明する。
図１は本発明を適用した分岐栓用泡沫網を形成する連続基材の３枚の各単位網の中心を結ぶ直線の傾斜角度を左右異にした１例を示す平面図である。図中、２０が無数の格子目を有する１枚の網から打ち抜いた連続基材、２２（２２ａ、２２ｂ、２２ｃ）がその単位網、２４（２４ａ、２４ｂ）がそれ等の隣接する単位網２２の間を結合する結合部である。この連続基材２０を打ち抜く網には直交するＸ軸、Ｙ軸と全ての横線、縦線をそれぞれ平行に配設して無数の格子目を設けた例えば６０メッシュの長尺材を使用する。そして、各単位網２２は分岐栓の放水筒部に装着した口金の吐出口を閉じるため、いずれも吐出口の径より少し径を大きくした円形体にする。又、各結合部２４は隣接する単位網２２の相対する円弧部分を含むようにして、いずれも細長く形成する。
【０００８】
このような連続基材２０を打ち抜く際、その連続基材２０を結合部２４で折り曲げて、それ等の３枚の単位網２２を重ね合わせた時、重なり合う格子目が互いにずれて斜めに交差するようにする。そこで、例えば中央に位置する単位網２２ａの中心点をＸ−Ｙ座標の原点０に一致させ、その単位網２２ａと結合する一方の単位網２２ｂの中心点Ｐ１を第１象限に決め、それ等のＯＰ１を結ぶ直線のＸ軸との角度をθ１とし、他方の単位網２２ｃの中心点Ｐ２を第４象限に決めて、ＯＰ２を結ぶ直線のＸ軸との角度をθ２として、左右の両単位網２２ｂ、ｃが接触するまでθ１、θ２を任意に選び、両単位網２２ａ、ｂの外形円に共通な接線２６又はその接線２６に平行な線を一方の折り曲げ線にし、両単位網２２ａ、ｃの外形円に共通な接線２８又は接線２８に平行な線を他方の折り曲げ線にする。なお、図ではθ１を６０°、θ２を１５°にした。
【０００９】
このようにして、１枚の網から連続基材２０の輪郭を定めて打ち抜くと、泡沫網の構成に必要な複数枚の例えば３枚の単位網２２を結合部２４を介在させて一度に打ち抜くことができる。それ故、打ち抜きの工程数を省力化できるばかりでなく、単位網間を結合するための工程等も必要としない。しかも、その後の取り扱いが容易となり、組み込み枚数を間違えることがない。そして、泡沫網を形成する際には、各折り曲げ線２６、２８の箇所で折り曲げて単位網２２を重ね合わせるだけでよく、重なり合う格子目を確実に互いにずらして斜めに交差させることができる。
【００１０】
組立時には、図２に示すように分岐栓３０の本体３２の下方に突出する放水筒部３４の内部に、矢印方向に移動させて水切り板３６と泡沫網３８を組み込み、それ等を口金４０で被って、その口金４０の放水筒部３４に対する嵌め込みによって装着する。すると、図３に示すように吐出口４２に泡沫網３８を設置できる。それ故、水切り板３６で乱流を整え、更に単位網２２を３枚重ね合わせた泡沫網３８で水の中に空気を良好に取り込んで泡沫を形成し、整流水にして放出できる。なお、４４が水道の蛇口との結合部、４６が水路切替ハンドル、４８（４８ａ、４８ｂ）が浄水器水路（図示なし）との結合部、５０が安全弁である。
【００１１】
しかしながら、重なり合う格子目を互いにずらして斜めに交差させるだけでは放出される水流に片寄りが発生する場合がある。そこで、図４に示すように単位網２２ｂ、ｃの角度θ１、θ２をいずれも３０°にすると、図５に示すように３枚の重ね合わせた単位網２２の重なり合う格子目５２（５２ａ、５２ｂ、５２ｃ）を互いに３０°ずつずらして斜めに交差させることができる。それ故、水流が均等に放出されるようになり、優れた整流効果が得られる。
【００１２】
なお、重ね合わせる単位網を２枚にする場合には、図６に示すように連続基材５４の一方の単位網５６ａを基準にして、その原点（中心点）０と他方の単位網５６ｂの中心点Ｐ３を結ぶ直線のＸ軸との角度θ３を２２．５°にする。すると、重なり合う格子目を互いに４５°ずつずらして斜めに交差させることができるため、優れた整流効果が得られる。
又、重ね合わせる単位網を４枚にする場合には、図７に示すように連続基材５８の一つの単位網６０ａを基準にして、その原点０と単位網６０ｂの中心点Ｐ４を結ぶ直線のＸ軸との角度θ４を１１．２５°にする。又、単位網６０ａの原点０と単位網６０ｃの中心点Ｐ５を結ぶ直線のＸ軸との角度θ５を１１．２５°とし、更に単位網６０ｂの中心点Ｐ４と単位網６０ｄの中心点Ｐ６を結ぶ直線のＸ軸との角度θ６を１１．２５°にする。すると、重なり合う格子目が互いに２２．５°ずつずれて斜めに交差するため、優れた整流効果が得られる。
【００１３】
【発明の効果】
以上説明した本発明によれば、請求項１記載の発明では無数の格子目を有する１枚の網から複数枚の単位網とその隣接する単位網間を結合する結合部とからなる連続した基材を打ち抜き、その連続基材を結合部で折り曲げて、それ等の単位網を重ね合わせるため、打ち抜き工程が１回で済み、単位網の重ね合わせ時に重なり合う格子目を互いにずらして斜めに交差させる工程も必要なくなる。それ故、工程数の省力化と取り扱いの簡易化を達成できると共に、組み込み枚数を間違えることがない。又、連続基材を打ち抜く際、その重ね合わせる単位網の重なり合う格子目が互いにずれて斜めに交差するように単位網間の相互位置を選択して打ち抜くため、その連続基材を結合部で折り曲げて、それ等の単位網を重ね合わせるだけで、重ね合わせた単位網の重なり合う格子目を簡単、確実に互いにずらして斜めに交差させることができる。従って、製品も安価になる。

BACKGROUND OF THE INVENTION
The present invention relates to a foam net that is attached to a fluid discharge port such as a faucet, a branch plug, a switching valve, a shower head, a water purifier, and the like to adjust the turbulent flow.
[0002]
[Prior art]
Conventionally, a faucet is attached to the tip of a water pipe. However, when water is discharged straight from the faucet, the water flowing in the pipe is a turbulent flow that has a fast center and a slow periphery. Therefore, as shown in FIG. 8, a turbulent flow is adjusted by attaching a foam net 12 and a draining plate 14 as a rectifying mechanism to the internal water channel near the discharge port of the faucet 10. At that time, when resistance is given to the water by the foam net 12, air is mixed into the water, foam is formed, and the turbulent flow can be rectified. Further, if the draining plate 14 is installed on the discharge port side, the water flow can be further rectified. In addition, air can be sent from the peripheral portion of the draining plate 14 to the foam net 12. In addition, 16 is a connection part with a water pipe, 18 is a handle for operation.
[0003]
Such a foam net is formed by punching an independent unit network having an outer diameter that substantially matches the diameter of the water channel inside the discharge port from a single mesh having an infinite number of grids. Are used in piles. However, if a plurality of independent unit networks are simply overlapped, the grids of the overlapping lattices may coincide and the rectifying effect may be greatly impaired. Therefore, in order not to make the overlapping lattices coincide with each other, a method of spot welding, insert molding, or the like is performed after the unit networks are shifted and overlapped so that the overlapping lattices cross each other obliquely. . The unit net is a metal net, a plastic net, or the like.
[0004]
[Problems to be solved by the invention]
However, when a foam net is manufactured in this way, punching must be performed for each unit net, and therefore there are many punching processes, and the number of handling increases, which makes it easy to mistake the number of sheets when assembling. In addition, if the steps of superimposing the unit nets so that the overlapping lattices are shifted from each other and obliquely intersect with each other are performed, the number of steps naturally increases and the cost increases.
[0005]
The present invention has been made paying attention to such a conventional problem. First, it is possible to achieve labor saving of the number of steps and simplification of the handling, and without overlapping the number of built-in units, the unit network to be overlapped. It is an object of the present invention to provide an inexpensive foam net that can be easily and surely shifted from each other and crossed diagonally.
It is another object of the present invention to provide a foam net that can provide a second excellent rectifying effect.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, the foam network according to the first object of the present invention comprises a unit network connecting a plurality of unit networks and adjacent unit networks from one network having innumerable lattices. When punching a continuous base material, it is punched by selecting the mutual position between the unit nets so that the overlapping lattices of the unit nets to be overlapped are obliquely shifted from each other, and the continuous base material is bent at the joint, Overlay these unit networks. Further, in the foam net corresponding to the second purpose, the overlapping grids of the unit nets overlapped with each other are obliquely shifted from each other.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
FIG. 1 is a plan view showing an example in which the inclination angle of a straight line connecting the centers of three unit nets of a continuous base material forming the foam network for a branch plug to which the present invention is applied is different from right to left. In the figure, 20 is a continuous base material punched from a single net having an infinite number of meshes, 22 (22a, 22b, 22c) is its unit network, and 24 (24a, 24b) is an adjacent unit network 22 thereof. It is the coupling | bond part which couple | bonds between. For the net for punching out the continuous base material 20, for example, a 60-mesh long material in which an orthogonal X axis, Y axis and all horizontal lines and vertical lines are arranged in parallel to provide innumerable lattices is used. Each unit network 22 is a circular body having a diameter slightly larger than the diameter of the discharge port in order to close the discharge port of the base attached to the water discharge tube portion of the branch plug. Each coupling portion 24 is formed to be elongated so as to include the arc portions of the adjacent unit nets 22 that face each other.
[0008]
When such a continuous base material 20 is punched, when the continuous base material 20 is bent at the connecting portion 24 and the three unit nets 22 are overlapped, the overlapping lattices are shifted from each other and cross obliquely. Like that. Therefore, for example, the center point of the unit network 22a located at the center is made to coincide with the origin 0 of the XY coordinate, and the center point P1 of one unit network 22b coupled to the unit network 22a is determined as the first quadrant, etc. Left and right units with θ1 as the angle between the straight line connecting OP1 and θ1 with the center point P2 of the other unit network 22c as the fourth quadrant, and θ2 as the angle with the X axis of the straight line connecting OP2 Θ1 and θ2 are arbitrarily selected until the meshes 22b and 22c come into contact with each other, the tangent line 26 common to the outer circles of the unit nets 22a and 22b or a line parallel to the tangent line 26 is set as one fold line, A tangent line 28 common to the outer circle of c or a line parallel to the tangent line 28 is set as the other fold line. In the figure, θ1 is 60 ° and θ2 is 15 °.
[0009]
Thus, when the outline of the continuous base material 20 is determined and punched out from a single net, a plurality of, for example, three unit nets 22 necessary for the configuration of the foam net are punched out at a time through the coupling portion 24. be able to. Therefore, not only can the number of punching processes be saved, but also a process for connecting the unit networks is not required. Moreover, subsequent handling becomes easy, and the number of built-in sheets is not mistaken. Then, when forming the foam net, it is only necessary to fold the unit nets 22 at the positions of the fold lines 26 and 28, so that the overlapping lattices can be surely shifted from each other and crossed obliquely.
[0010]
At the time of assembly, as shown in FIG. 2, a draining plate 36 and a foam net 38 are assembled by moving in the direction of the arrow inside the water discharge tube 34 projecting downward from the main body 32 of the branch plug 30. The cap 40 is attached by fitting into the water discharge tube 34. Then, as shown in FIG. 3, a foam net 38 can be installed at the discharge port 42. Therefore, turbulent flow is adjusted by the draining plate 36, and air is satisfactorily taken into the water by the foam network 38 in which the three unit networks 22 are overlapped to form foam, which can be discharged as rectified water. In addition, 44 is a coupling | bond part with a faucet, 46 is a water-channel switching handle, 48 (48a, 48b) is a coupling | bond part with a water purifier water channel (not shown), 50 is a safety valve.
[0011]
However, if the overlapping grids are shifted from each other and crossed obliquely, the discharged water flow may be displaced. Therefore, if the angles θ1 and θ2 of the unit nets 22b and c are both 30 ° as shown in FIG. 4, the overlapping lattice 52 (52a and 52b) of the three unit nets 22 as shown in FIG. , 52c) can be crossed diagonally at 30 ° intervals. Therefore, the water flow is discharged evenly, and an excellent rectifying effect is obtained.
[0012]
When two unit nets are to be overlapped, as shown in FIG. 6, with reference to one unit net 56a of the continuous base material 54, the origin (center point) 0 and the other unit net 56b The angle θ3 with the X axis of the straight line connecting the center points P3 is set to 22.5 °. Then, since the overlapping lattices can be shifted by 45 ° from each other and obliquely intersected, an excellent rectifying effect can be obtained.
When the unit nets to be overlapped are four, as shown in FIG. 7, a straight line connecting the origin 0 and the center point P4 of the unit net 60b with reference to one unit net 60a of the continuous base material 58. The angle θ4 with respect to the X axis is set to 11.25 °. Further, the angle θ5 between the origin 0 of the unit network 60a and the X axis of the straight line connecting the center point P5 of the unit network 60c is 11.25 °, and the center point P4 of the unit network 60b and the center point P6 of the unit network 60d are The angle θ6 with the X axis of the connecting straight line is set to 11.25 °. Then, since the overlapping lattices are obliquely crossed with a shift of 22.5 °, an excellent rectifying effect can be obtained.
[0013]
【The invention's effect】
According to the present invention described above, according to the first aspect of the present invention, a continuous base comprising a plurality of unit networks from one network having an infinite number of lattices and a connecting portion connecting adjacent unit networks. The material is punched, the continuous base material is bent at the joint, and these unit nets are overlapped, so that the punching process is only one time. No process is required. Therefore, labor saving of the number of processes and simplification of handling can be achieved, and the number of built-in sheets is not mistaken. In addition, when punching a continuous base material, the continuous base material is bent at the connecting portion so that the mutual positions of the unit nets can be selected and punched so that the overlapping lattices of the unit nets to be overlapped are obliquely shifted from each other. By simply superimposing these unit networks, the overlapping lattices of the superimposed unit networks can be easily and reliably shifted from each other and crossed obliquely. Therefore, the product is also inexpensive.
[0014]
According to the second aspect of the present invention, since the overlapping lattices of the unit nets that are overlapped are obliquely intersected with each other, the water flow is evenly discharged and an excellent rectifying effect can be exhibited.
