Description

【0001】
【発明の属する技術分野】
本発明は、誤操作防止用キャップ装置およびこれを用いたバルブ装置に関する。
【0002】
【従来の技術】
従来、水洗便器に洗浄水を供給する給水路には、止水栓や洗浄水を流す操作を行うためのフラッシュバルブが設けられている。これら止水栓やフラッシュバルブなどのバルブ装置には、通常、洗浄水の水量を調節するための調節手段が設けられている。図5に示すように、止水栓100は、主流路101を有するボディ102と、ボディ102の開口を閉じる蓋体103と、主流路101に設けられた弁体104と、弁体104を進退させて止水または流量調節するスピンドル105とを備えている。止水栓100では、主流路101の流入口106から加わる水道源の水圧が弁体104を押し上げて主流路101を水が流れる。
【0003】
この止水栓100において、止水または流量調節するには、スピンドル105の操作部105aの溝105bにドライバ等の工具を合わせてスピンドル105を回転することにより、弁体104のストロークを調節することにより行なう。
【0004】
しかし、操作部105aが外部に露出しているため、公共施設などに水洗便器を設置した場合、いたずらなどにより操作部105aが回転操作されることがある。このような操作部105aの回転操作により、水洗便器への洗浄水が流れなくなったり、過剰に流れることになる。
【0005】
このような対策として、図6のように止水栓100の操作部105aを覆うキャップ107と、キャップ107を支持する支持体108と、キャップ107と支持体108との間に介在する固定部材109とを備えている。キャップ107は、側壁107aの内面全周にガイド溝107bと、キャップ107の外側から内側に向けて貫通する操作用透孔(図示しない)とを有している。固定部材109は、支持体108に固定されるとともに、操作用透孔107cを介してキャップ107を支持体108に対して抜止するように操作可能に構成するものがある(例えば、特許文献1参照のこと。)。
【0006】
この他、支持体に固定部材を締め込む方法として他のものが挙げられる。この方法は、正六角形状の支持体に固定部材を締め込んで水栓本体を固定するものである(例えば、特許文献2参照のこと。)。

【発明が解決しようとする課題】
しかし、この従来の誤操作防止キャップでは、固定部材1本で固定するため、キャップに異常な力が連続的に加わると固定部材が弛み易くなり、キャップが容易に取り外せてしまい、いたずらされるおそれがある。また、操作部にキャップを被せた後、蓋体に挿入された固定部材を所定の位置まで弛めるため、位置調整等の作業が煩わしいといった問題があった。
【0009】
この他、支持体に固定部材を締め込む方法としてある正六角形状の支持体に固定部材を締め込んで水栓本体を固定するものでは、支持体の向きが不規則なため、固定部材は支持体の頂点を締め込む可能性があり、この場合に異常な力が繰り返し加わると固定部材が弛んで外れることになる。固定部材の軸の交差角度が180°で2本設けた場合でも支持体の頂点を締め込む可能性があり、同様の問題が考えられる。
【0010】
本発明は、上記従来の技術の問題を解決するものであり、キャップの固定力をさらに強固にし簡単に外されることなく、いたずらによる誤操作を防止するとともに、キャップの取付け、取外し作業を簡便なものとした誤操作防止用キャップ装置およびバルブ装置を提供することを目的とする。
【0011】
【課題を解決するための手段】
上記課題を解決するために請求項1は、操作部を覆うキャップと、平面部および頂点部を有してなるキャップを支持する支持体と、キャップを前記支持体に固定する固定部材を備えた誤操作防止用キャップ装置において、キャップの側面に固定部材を螺合するためのネジ孔を少なくとも2箇所設けるとともに、ネジ孔を通じて何れか一方の固定部材が支持体の平面部、他方が頂点部を締め付けてキャップを固定されるような角度に配置したことを特徴とした。
【0012】
これにより、1箇所で固定するよりも強固に固定できる。また、支持体の方向性が如何なる場合でも、必ず一方の固定部材が平面部を締め込んでいるのでキャップは、強固に固定されて簡単に回転させることができない。仮に固定部材が弛んだ場合でもキャップを回転させる際に固定部材が支持体の頂点部に引っ掛かって、取外しが困難となり、容易にいたずら操作をさせない。
【0013】
請求項2は、前記支持体を正六角形状部に形成するとともに、少なくとも2本設けた前記固定部材の中心軸の交差角度が30°、90°または150°の何れかをなして前記キャップを前記支持体に固定することを特徴とした。
【0014】
これにより、支持体の方向性が如何なる場合でも、固定部材の一方が正六角形状の平面部、他方が頂点を締め込み、キャップを強固に固定することができ、容易には取り外せない。
【0015】
請求項3は、前記支持体を正方形状部に形成するとともに、少なくとも2本設けた前記固定部材の中心軸の交差角度が45°または135°何れかの角度をなして前記キャップを前記支持体に固定したことを特徴とした。
【0016】
これにより、支持体の方向性が如何なる場合でも、固定部材の一方が正方形状の平面部、他方が頂点を締め込み、キャップを強固に固定することができ、容易には取り外せない。
【0017】
請求項4は、流水路に設けられた止水または流量調節するための操作部と、前記操作部を覆うキャップと、平面部および頂点部を有してなるキャップを支持する支持体と、キャップを前記支持体に固定する固定部材を備えたバルブ装置において、キャップの側面に固定部材を螺合するためのネジ孔を少なくとも2箇所設けるとともに、ネジ孔を通じて何れか一方の固定部材が支持体の平面部、他方が頂点部を締め付けてキャップを固定されるような角度に配置したことを特徴とした。
【0018】
これにより、キャップは、強固に固定されて簡単に回転させることができず、取り外しが困難となり、いたずらなどで操作部を容易に操作されないので洗浄水が流れなくなり、洗浄不良を起こしたり、過剰に流れるのを防止することができる。
【0019】
【発明の実施の形態】
以上説明した本発明の構成・作用を一層明らかにするために、以下本発明の好適な実施例を水洗便器に使用するバルブ装置である止水栓を用いて説明する。
【0020】
図1は、本発明のキャップを備えた止水栓を示した図である。図2は、キャップの断面を示した図である。図3は、支持体の形状に適したキャップのネジ孔の位置を示した図である。図4は、キャップに固定部材を締め込んだ状態を示した図である。
【0021】
本発明に係る誤操作防止キャップを用いる止水栓10は、図1に示すように主流路11と流入口12を有する止水栓本体13と、流路を開閉する弁体14と、弁体14の開ストロークを規制するスピンドル15と、スピンドル15を上下動させるスクリュー16と、スピンドル15の状態を保持するスピンドルガイド17と、スピンドルガイド17を支える支持体18とで構成されている。
【0022】
支持体18の外周面には、スクリュー16を覆い隠すキャップ19を螺合するための雄ネジ部18aを設けている。雄ネジ部18aの上方には支持体18を止水栓本体13に組付ける際の締付け用として、スパナ等の工具掛かり部18bを設けている。
【0023】
一般的に、止水栓10において、止水あるいは流量調節する場合は、スクリュー16に設けた溝16aにドライバ等の工具を合せて回転させるとスピンドル15が上下動して弁体14の開ストロークを調節する。
【0024】
一方、図2に示すようにキャップ19には、固定部材20を螺合するためにキャップ19の外側からキャップ19の中心に向けて貫通したネジ孔19aを2箇所設けている。ネジ孔19aの配置は、固定部材20の一方が、必ず支持体18の平面部18cを締め込むようにしている。そのため、一方が支持体18の頂点部18dを締め込んだとしても、他方が平面部18cを締め込むので強固に固定される。仮に固定部材20が弛んだとしても、キャップ19を回転するときに固定部材20が支持体18の頂点部18dに引っ掛かって取り外すことは困難である。この場合、支持体18の工具掛かり部18bと平面部18cは同一箇所である。なお、頂点部18dは、固定部材20の大きさ(外径)に比べ小さい面取りまたは曲面加工がなされていれば、機能上問題ない。通常面取りはC1からC2で曲面加工はR1からR2である。
【0025】
例えば、支持体18が正六角形状であれば、図3の(a)に示すようにネジ孔19aの配置は、30°、90°または150°の何れかに設定するとよい。
また、支持体18が正方形状であれば、図3の(b)に示すようにネジ孔19aの配置は、45°または135°の何れかに設定するとよい。
【0026】
次に、支持体18にキャップ19を取付ける方法について説明する。まず、キャップ19に設けた2箇所のネジ孔19aにキャップ19を固定するための固定部材20を仮止めしておく。給水路(図示しない)に取付けた止水栓10のスクリュー16で流水量の調節を終えた後、固定部材20を仮止めした状態のキャップ19を支持体18に所定の位置まで締込み取付ける。その後、2箇所に仮止めした固定部材20の締め付けように設けられた凹部に六角レンチ等の工具を用いて順次締込みキャップ19を固定する。ここで、固定部材20は、一般に用いられる止めネジ等である。
【0027】
図4に支持体18が正六角形状、正方形状とした場合のキャップ19の固定状態を示すが、何れの場合も1箇所は支持体18の平面部18c、他の箇所は頂点部18dを締め込んでいる。尚、固定部材20の締め込みの順序は前述に限定する必要はなく、キャップ19を支持体18に取付けた後に工具を用いて締込んでもよい。
【0028】
図4の(a)では4個、図4の(b)では3個の固定部材を示しているが、平坦部18cを締め付ける固定部材20aと、頂点部18dを締め付ける他の固定部材20が1箇所以上あれば、目的を達せられる。すなわち、少なくとも2本以上の固定部材を締め込めばよい。
【0029】
なお、固定部材20を締め込む際、固定部材の軸が必ず支持体18の平面部18cや頂部18dに対し垂直になるとは限らないが、最初に締め込む固定部材の1箇所が必ず平面部18cを締め込むことになる。
例えば、支持体18が正方形状の場合について説明する。図7に示した状態は、固定部材20aの軸が支持体18の平面部18cに対し垂直にならない状態である。この状態で固定部材20aを締め付けていくと固定部材20aの軸が平面部18cに対し垂直になるようにキャップ19が回転し、図4の(b)に示した状態となり固定部材20aは必ず平面部18cを締め込むことになる。
【0030】
このようにして、固定部材20を締め込むと、必ず1箇所は支持体18の平面部18cを締め込むため、キャップ20に異常な力が繰り返し加わったとしても固定部材は弛みにくく、キャップ19を取り外すことは困難である。
【0031】
また、固定部材20を六角レンチ等の工具を用いて締め込むだけで、キャップ19を固定できるので、従来のような固定部材の調整が不要になり、取付け作業も簡便なものになる。
【0032】
尚、この発明は上記実施例に限られるものではなく、その要旨を逸脱しない範囲において種々の態様において実施することが可能であり、例えば次のような変形も可能である。
【0033】
支持体の断面形状を正方形、正六角形にした場合について説明したが、正八角形あるいは、円状に平面部を2箇所設けた形状であってもよく、夫々の形状に適応した位置(平面部と頂点部を締め込む)に固定部材を配置してもよい。
【0034】
上記実施の形態では、止水栓に適用した構成について説明したが、これに限らず、いたずらによる操作を防止する必要がある操作部であれば、他のバルブ、例えばフラッシュバルブであってもよい。
【0035】
さらに他の態様によれば、電気スイッチなどの操作部において、いたずら操作を防止する必要性の高い箇所に適用してもよい。
【0036】
【発明の効果】
本発明によって、固定力をさらに強固にし簡単に外されることなく、いたずらによる誤操作を防止するとともに、キャップの取付け、取外し作業を簡便なものとした誤操作防止用キャップ装置およびバルブ装置を提供することができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to an erroneous operation preventing cap device and a valve device using the same.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, a water supply path for supplying flush water to a flush toilet is provided with a stopcock and a flush valve for performing an operation of flowing flush water. These valve devices such as water stopcocks and flush valves are usually provided with adjusting means for adjusting the amount of washing water. As shown in FIG. 5, the water stopcock 100 includes a body 102 having a main flow path 101, a cover 103 that closes an opening of the body 102, a valve element 104 provided in the main flow path 101, and an advancing / retreating valve element 104. And a spindle 105 for stopping water or adjusting the flow rate. In the water stopcock 100, the water pressure of the water source applied from the inflow port 106 of the main flow path 101 pushes up the valve body 104, and water flows through the main flow path 101.
[0003]
In the water stopcock 100, in order to stop water or adjust the flow rate, the stroke of the valve body 104 is adjusted by rotating a spindle 105 by aligning a tool such as a screwdriver with a groove 105b of an operation portion 105a of a spindle 105. Performed by
[0004]
However, since the operation unit 105a is exposed to the outside, when the flush toilet is installed in a public facility or the like, the operation unit 105a may be rotated by mischief or the like. By such a rotation operation of the operation unit 105a, the flush water to the flush toilet stops flowing or excessively flows.
[0005]
As a countermeasure for this, as shown in FIG. 6, a cap 107 covering the operation portion 105a of the water stopcock 100, a support 108 supporting the cap 107, and a fixing member 109 interposed between the cap 107 and the support 108. And The cap 107 has a guide groove 107b all around the inner surface of the side wall 107a and an operation through hole (not shown) penetrating from the outside to the inside of the cap 107. The fixing member 109 is configured to be fixed to the support member 108 and to be operable so as to prevent the cap 107 from being pulled out of the support member 108 through the operation hole 107c (for example, see Patent Document 1). That.)
[0006]
In addition, there are other methods for fastening the fixing member to the support. In this method, a faucet main body is fixed by fastening a fixing member to a regular hexagonal support (for example, see Patent Document 2).

[Problems to be solved by the invention]
However, in this conventional erroneous operation prevention cap, since the fixing member is fixed with one fixing member, when an abnormal force is continuously applied to the cap, the fixing member is easily loosened, and the cap can be easily removed, which may cause tampering. is there. In addition, after the operation unit is covered with the cap, the fixing member inserted into the lid is loosened to a predetermined position, so that there is a problem that the work of position adjustment and the like is troublesome.
[0009]
In addition, in a method of fastening the fixing member to a regular hexagonal support, which is a method of fastening the fixing member to the support, and fixing the faucet main body, since the orientation of the support is irregular, the fixing member is not supported. The apex of the body may be pinched, and in this case, if an abnormal force is repeatedly applied, the fixing member will be loosened and come off. Even when two fixing axes are provided at a crossing angle of 180 °, the top of the support may be tightened, and the same problem is conceivable.
[0010]
SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems of the prior art, and further enhances the fixing force of the cap to prevent erroneous operation due to mischief without being easily removed, and to simplify the operation of attaching and removing the cap. It is an object of the present invention to provide a cap device and a valve device for preventing erroneous operation.
[0011]
[Means for Solving the Problems]
In order to solve the above problem, claim 1 includes a cap for covering the operation unit, a support for supporting the cap having a flat portion and a vertex, and a fixing member for fixing the cap to the support. In the erroneous operation prevention cap device, at least two screw holes for screwing the fixing member to the side surface of the cap are provided, and one of the fixing members tightens the flat portion of the support and the other tightens the top portion through the screw hole. The cap is fixed at an angle so as to be fixed.
[0012]
Thereby, it can be fixed more firmly than fixed at one place. Also, regardless of the direction of the support, the cap is firmly fixed and cannot be easily rotated because one fixing member always tightens the flat part. Even if the fixing member is loosened, when the cap is rotated, the fixing member is caught on the apex of the support, making it difficult to remove the cap.
[0013]
Claim 2 forms the support body in a regular hexagonal portion and forms the cap at an intersection angle of 30 °, 90 ° or 150 ° with the central axis of at least two fixing members. It is characterized in that it is fixed to the support.
[0014]
Thus, regardless of the orientation of the support, one of the fixing members can be fixed to a regular hexagonal flat portion and the other to the vertex, and the cap can be firmly fixed and cannot be easily removed.
[0015]
A third aspect of the present invention is that the support is formed in a square-shaped portion, and the cap has a crossing angle of 45 ° or 135 ° with respect to a central axis of at least two of the fixing members. It was characterized in that it was fixed to
[0016]
Thus, regardless of the orientation of the support, one of the fixing members can be tightly fixed to the square flat portion and the other to the top, and the cap can be firmly fixed, and cannot be easily removed.
[0017]
Claim 4 is an operation unit provided in the flowing water channel for adjusting water stoppage or flow rate, a cap for covering the operation unit, a support for supporting the cap having a flat portion and an apex portion, and a cap. In a valve device provided with a fixing member for fixing the fixing member to the support, at least two screw holes for screwing the fixing member to the side surface of the cap are provided, and one of the fixing members of the support is provided through the screw hole. The flat portion and the other are arranged at an angle such that the cap is fixed by tightening the apex portion.
[0018]
As a result, the cap is firmly fixed and cannot be easily rotated, making it difficult to remove.Since the operation unit is not easily operated due to mischief, cleaning water does not flow, causing poor cleaning or excessive cleaning. Flow can be prevented.
[0019]
BEST MODE FOR CARRYING OUT THE INVENTION
In order to further clarify the configuration and operation of the present invention described above, a preferred embodiment of the present invention will be described below using a water stopcock which is a valve device used for a flush toilet.
[0020]
FIG. 1 is a view showing a water stopcock provided with a cap of the present invention. FIG. 2 is a diagram showing a cross section of the cap. FIG. 3 is a diagram showing positions of screw holes of the cap suitable for the shape of the support. FIG. 4 is a diagram illustrating a state where the fixing member is tightened to the cap.
[0021]
A water stopcock 10 using the erroneous operation prevention cap according to the present invention includes a water stopcock main body 13 having a main flow path 11 and an inflow port 12 as shown in FIG. 1, a valve element 14 for opening and closing the flow path, and a valve element 14. The spindle 15 comprises a spindle 15 for regulating the opening stroke of the spindle 15, a screw 16 for moving the spindle 15 up and down, a spindle guide 17 for maintaining the state of the spindle 15, and a support 18 for supporting the spindle guide 17.
[0022]
On the outer peripheral surface of the support 18, a male screw portion 18 a for screwing a cap 19 covering the screw 16 is provided. Above the male screw portion 18a, a tool hook portion 18b such as a spanner is provided for fastening when the support 18 is assembled to the water stopcock body 13.
[0023]
Generally, when water is stopped or the flow rate is adjusted in the water stopcock 10, when a tool such as a screwdriver is aligned with a groove 16 a provided in the screw 16 and rotated, the spindle 15 moves up and down to open the valve body 14. Adjust
[0024]
On the other hand, as shown in FIG. 2, the cap 19 is provided with two screw holes 19 a penetrating from the outside of the cap 19 toward the center of the cap 19 for screwing the fixing member 20. The arrangement of the screw holes 19 a is such that one of the fixing members 20 always tightens the flat portion 18 c of the support 18. For this reason, even if one side tightens the apex portion 18d of the support member 18, the other side tightens the flat portion 18c, so that it is firmly fixed. Even if the fixing member 20 is loosened, it is difficult to remove the fixing member 20 because the fixing member 20 is caught on the vertex 18 d of the support 18 when rotating the cap 19. In this case, the tool holding portion 18b and the flat portion 18c of the support 18 are the same. The apex portion 18d has no problem in function as long as the chamfer or the curved surface processing is smaller than the size (outer diameter) of the fixing member 20. Normally, chamfering is from C1 to C2, and curved surface processing is from R1 to R2.
[0025]
For example, if the support 18 has a regular hexagonal shape, the arrangement of the screw holes 19a may be set to any of 30 °, 90 °, or 150 ° as shown in FIG.
If the support 18 has a square shape, the arrangement of the screw holes 19a may be set to either 45 ° or 135 ° as shown in FIG.
[0026]
Next, a method of attaching the cap 19 to the support 18 will be described. First, a fixing member 20 for fixing the cap 19 to two screw holes 19a provided in the cap 19 is temporarily fixed. After adjusting the amount of flowing water with the screw 16 of the water stopcock 10 attached to a water supply channel (not shown), the cap 19 with the fixing member 20 temporarily fixed is screwed to the support 18 to a predetermined position. Thereafter, the tightening cap 19 is sequentially fixed to a concave portion provided to tighten the fixing member 20 temporarily fixed at two places, using a tool such as a hexagon wrench. Here, the fixing member 20 is a commonly used set screw or the like.
[0027]
FIG. 4 shows the fixed state of the cap 19 when the support 18 has a regular hexagonal shape or a square shape. In each case, one portion is tightened by the flat portion 18c of the support 18 and the other portion is tightened by the apex portion 18d. It is crowded. Note that the order of tightening the fixing member 20 does not need to be limited to the above, and the fixing may be performed by using a tool after attaching the cap 19 to the support 18.
[0028]
Although FIG. 4A shows four fixing members and FIG. 4B shows three fixing members, one fixing member 20a for tightening the flat portion 18c and another fixing member 20 for tightening the apex portion 18d are one. If there are more than one place, you can achieve your purpose. That is, at least two or more fixing members may be tightened.
[0029]
When the fixing member 20 is tightened, the axis of the fixing member is not always perpendicular to the flat portion 18c or the top portion 18d of the support member 18. Will be tightened.
For example, a case where the support 18 has a square shape will be described. The state shown in FIG. 7 is a state in which the axis of the fixing member 20a is not perpendicular to the plane portion 18c of the support 18. When the fixing member 20a is tightened in this state, the cap 19 rotates so that the axis of the fixing member 20a is perpendicular to the plane portion 18c, and the state shown in FIG. The part 18c will be tightened.
[0030]
In this manner, when the fixing member 20 is tightened, one place always tightens the flat portion 18c of the support member 18. Therefore, even if an abnormal force is repeatedly applied to the cap 20, the fixing member is not easily loosened, and the cap 19 is fixed. It is difficult to remove.
[0031]
Further, since the cap 19 can be fixed only by tightening the fixing member 20 using a tool such as a hexagon wrench, the adjustment of the fixing member as in the related art is not required, and the mounting operation is simplified.
[0032]
The present invention is not limited to the above-described embodiment, and can be implemented in various modes without departing from the gist of the invention. For example, the following modifications are possible.
[0033]
Although the case where the cross-sectional shape of the support is a square or a regular hexagon has been described, the support may be a regular octagon or a shape in which two flat portions are provided in a circular shape, and a position (flat portion and flat portion) adapted to each shape may be used.
