Description
この発明は、衝撃緩衝、脈動吸収、ショックアブソーバ等に用いられるアキュムレータに関するものであり、更に述べると、ブラダを内蔵するアキュムレータに関するものである。 The present invention relates to an accumulator used for shock buffering, pulsation absorption, shock absorber, and the like. More specifically, the present invention relates to an accumulator incorporating a bladder.
アキュムレータは、ブラダを内蔵しているが、このブラダはゴムや合成樹脂等の弾性材料で形成され、その開口部には固定用のフランジ部が設けられている。このブラダをアキュムレータに挿着する際には、アキュムレータの本体開口部から前記ブラダを挿入している（例えば、特許文献１、参照）。 The accumulator has a built-in bladder, which is made of an elastic material such as rubber or synthetic resin, and has a fixing flange at its opening. When the bladder is inserted into the accumulator, the bladder is inserted from the main body opening of the accumulator (see, for example, Patent Document 1).
本体開口部の内周面には、蓋体が螺着されるねじ部とブラダのフランジ部を係止する係止段部とが設けられている。そのため、ブラダを本体開口部内に挿入する際に、該ブラダは、前記ねじ部に接触し破損することがあるとともに、該ブラダが前記係止段部に引っかかり円滑に挿入するが困難となる。 On the inner peripheral surface of the main body opening portion, there are provided a screw portion to which the lid is screwed and a locking step portion for locking the flange portion of the bladder. For this reason, when the bladder is inserted into the opening of the main body, the bladder may come into contact with the screw portion and be damaged, and it becomes difficult for the bladder to be caught by the locking step portion and smoothly inserted.
この発明は、上記事情に鑑み、ブラダを挿着する際に該ブラダが破損しないようにすることを目的とする。他の目的は円滑にブラダを挿着できるようにすることである。 In view of the above circumstances, an object of the present invention is to prevent the bladder from being damaged when the bladder is inserted. Another purpose is to allow the bladder to be inserted smoothly.
この発明は、内周面にねじ部を有する本体開口部の外周面に、ブラダ挿入シートの固定部を巻き付け、筒状にして固定する工程と、前記ブラダ挿入シートを折り返して該シートの覆い部を前記本体開口部内に挿入し、前記ねじ部を覆う工程と、前記本体開口部内にブラダを挿入する工程と、前記ブラダ挿入シートを前記本体開口部から取り外す工程と、を備えていることを特徴とする。 The present invention includes a step of winding a fixing portion of a bladder insertion sheet around the outer peripheral surface of a main body opening having a threaded portion on the inner peripheral surface to fix it in a cylindrical shape, and folding the bladder insertion sheet to cover the sheet A step of covering the screw portion, a step of inserting a bladder into the main body opening, and a step of removing the bladder insertion sheet from the main body opening. And
この発明は、内周面にねじ部と係止段部とを有する本体開口部の外周面に、ブラダ挿入シートの固定部を巻き付け、筒状にして固定する工程と、前記ブラダ挿入シートを折り返して該シートの覆い部を前記本体開口部内に挿入し、前記ねじ部と前記係止段部を覆う工程と、前記本体開口部内にブラダを挿入する工程と、前記ブラダ挿入シートを前記本体開口部から取り外す工程と、前記ブラダのフランジ部を前記係止段部に係合させる工程と、前記本体開口部に蓋体を螺着して前記フランジ部を押圧し固定する工程と、を備えていることを特徴とする。 The present invention includes a step of winding a fixing portion of a bladder insertion sheet around an outer peripheral surface of a main body opening portion having a screw portion and a locking step portion on an inner peripheral surface, and fixing the bladder insertion sheet in a tubular shape, and folding back the bladder insertion sheet. Inserting a cover portion of the sheet into the body opening, covering the screw portion and the locking step, inserting a bladder into the body opening, and inserting the bladder insertion sheet into the body opening. A step of engaging the flange portion of the bladder with the locking step portion, and a step of screwing a lid body onto the main body opening portion to press and fix the flange portion. It is characterized by that.
この発明の前記ブラダ挿入シートは、長方形状のビニールシートであり、前記固定部は一方の長辺側に形成され、該固定部には粘着テープが設けられていることを特徴とする。 The bladder insertion sheet of the present invention is a rectangular vinyl sheet, wherein the fixing portion is formed on one long side, and an adhesive tape is provided on the fixing portion.
この発明は、以上のように構成したので、本体開口部内にブラダを挿着する際には、該本体開口部の内周面のねじ部はブラダ挿入シートにより覆われている。そのため、ブラダが前記ねじ部に直接接触することがないので、破損事故を防止することができる。又、本体開口部の内周面のねじ部と係止段部をブラダ挿入シートにより覆うと、ブラダは該シートに案内されながら滑るようにして降下する。そのため、ブラダを円滑に挿入することができる。 Since the present invention is configured as described above, when the bladder is inserted into the main body opening, the thread portion on the inner peripheral surface of the main body opening is covered with the bladder insertion sheet. Therefore, since the bladder does not directly contact the threaded portion, it is possible to prevent a breakage accident. Further, when the screw portion and the locking step portion on the inner peripheral surface of the opening of the main body are covered with the bladder insertion sheet, the bladder descends while sliding while being guided by the sheet. Therefore, the bladder can be inserted smoothly.
この発明の実施の形態を図１〜図５により説明する。
アキュムレータの容器本体１の一端には、図示しない流体出入口が設けられ、他端には本体開口部３が設けられている。この本体開口部３の内周面には、ねじ部３ａと係止段部３ｂが設けられている。
An embodiment of the present invention will be described with reference to FIGS.
A fluid inlet / outlet (not shown) is provided at one end of the
前記本体開口部３の外周面は、ブラダ挿入シート５により覆われている。
図１に示す様に、このシート５は、長方形状のビニールシートであり、例えば、長辺の長さは、前記本体開口部３の外周長さより長く形成され、又、短辺５ｂの長さは、本体開口部３の長さの１．５倍以上の長さに形成されている。前記シート５は、固定部５ｃと覆い部５ｄとを備えており、その長辺５ａの一方側に位置する固定部５ｃには、粘着テープ７が設けられている。
The outer peripheral surface of the main body opening 3 is covered with a
As shown in FIG. 1, the
ブラダ９は、ゴムや合成樹脂等の弾性材料で形成され、その開口部にはフランジ部９ａが設けられている。
The bladder 9 is formed of an elastic material such as rubber or synthetic resin, and a
次に本件実施の形態の作動について説明する。
図２に示すように、本体開口部３の外周面に粘着テープ７を押し付けながらビニールシート５の固定部５ｃを巻き付けて筒状にしながら前記固定部５ｃを固定する。このビールシート５は前記外周面全周を完全に覆うために、一回半ほど巻き付けることが好ましい。
Next, the operation of the present embodiment will be described.
As shown in FIG. 2, the
図３に示すように、前記ビニールシート５の覆い部５ｄを内側に折り込んで前記本体開口部３内に挿入し、前記ねじ部３ａと前記係止段部３ｂを前記ビニールシートの覆い部５ｃで完全に覆う。
As shown in FIG. 3, the
図４に示すように、ブラダ９を持ち、該ブラダ９の底部９ｂから本体開口部３内に挿入する。この時、ブラダ９は、ビニールシート５の固定部５ｃに案内され滑るようにして降下する。そのため、ねじ部３ａや係止段部３ｂに直接接続することがないので、ブラダ９の損傷を防止できるとともに、円滑に挿入することもでできる。
As shown in FIG. 4, the bladder 9 is held and inserted into the main body opening 3 from the
ブラダ９を挿入後、本体開口部３から前記ビニールシート５を取り外す。そして、図５に示すように、ブラダのフランジ部９ａを係止段部３ｂに係止させた後、該本体開口部３に蓋体１２を螺着して前記フランジ部９ａを押圧して固定する。なお、１５は、ブラダ９内に不活性ガス等のガスを給排する給排弁、を示す。
After inserting the bladder 9, the
この実施の形態は、上記に限定されるものではなく、例えば、次の様にして良い。
（１）ブラダ挿入シートを、ビニールシートの代わりに、布、細網状シート等を用いても良い。
（２）ブラダ挿入シートに、ブラダの滑りを良くするために,油等を塗布しても良い。
（３）ビニールシートの固定部に粘着テープを設ける代わりに、輪ゴムや永久磁石等を用い、前記固定部を着脱自在に固定するようにしても良い。
This embodiment is not limited to the above, and may be as follows, for example.
(1) The bladder insertion sheet may be a cloth, a reticulated sheet or the like instead of the vinyl sheet.
(2) Oil or the like may be applied to the bladder insertion sheet in order to improve sliding of the bladder.
(3) Instead of providing the adhesive tape on the fixing portion of the vinyl sheet, the fixing portion may be detachably fixed using a rubber band, a permanent magnet, or the like.
