Description

本発明は、蝶番を分離して、扉をボックス本体から容易に取り外すことのできる蝶番に関するものである。   The present invention relates to a hinge capable of separating a hinge and easily removing a door from a box body.

ボックス本体の開口を蝶番により取り付けた扉により開閉する分電盤や配電盤及び通信機器等の電気・電子機器収納ボックスは、ボックス本体内に電気・電子機器類の設置工事等において扉が邪魔となる場合には扉を外して工事作業を行い作業終了後に再度扉を取り付けることがある。     The electrical box and distribution box and electrical / electronic equipment storage boxes that open and close with a hinged door that opens the box body will interfere with the installation of electrical / electronic equipment in the box body. In some cases, the door is removed and the construction work is performed, and the door is attached again after the work is completed.

このような場合に、蝶番ピンを外して蝶番を分離して行うものを普通としている。そこで、蝶番ピンの着脱を容易とするものとして、一方の蝶番金具の軸筒部に摺動自在に嵌合した蝶番ピンにラックを形成して、蝶番金具に前記ラックと噛合する小歯車を設置して工具係合部を形成した該小歯車の頭部を蝶番金具の表面に露出させて、該工具係合部にドライバー等の工具を係合して小歯車を回転させて軸ピンを軸筒部内で摺動させて、他方の蝶番金具の軸受部に着脱自在としたものがある(例えば、特許文献1、2参照)。     In such a case, it is normal to remove the hinge pin and separate the hinge. Therefore, in order to make it easy to attach and detach the hinge pin, a rack is formed on the hinge pin that is slidably fitted to the shaft tube portion of one hinge bracket, and a small gear that meshes with the rack is installed on the hinge bracket. Then, the head of the small gear that forms the tool engaging portion is exposed on the surface of the hinge metal fitting, and a tool such as a screwdriver is engaged with the tool engaging portion to rotate the small gear to rotate the shaft pin. Some of them are slidable in the cylindrical part so that they can be attached to and detached from the bearing part of the other hinge fitting (see, for example, Patent Documents 1 and 2).

ところが、前記したものは蝶番金具の表面に露出させた小歯車の頭部の工具係合部にドライバー等の工具を係合して小歯車を回転させておこなうものであるため、ドライバー等の工具を使用するための作業空間を確保するために扉を大きく開ける必要がある(特許文献1図2参照)。そのため、電気・電子機器収納ボックスの設置場所により扉を大きく例えば90度以上に開けることができない作業空間が狭い場合には小歯車の工具係合部にドライバー等の工具を垂直に係合することが困難な場合があり、小歯車を回転させる作業が困難であった。     However, since the above-mentioned is performed by rotating a small gear by engaging a tool such as a screwdriver with a tool engaging portion of the head of a small gear exposed on the surface of the hinge metal, a tool such as a screwdriver is used. In order to secure a working space for using the door, it is necessary to open the door widely (see Patent Document 1 FIG. 2). For this reason, if the working space is too small to open, for example, 90 degrees or more, depending on the installation location of the electrical / electronic equipment storage box, a tool such as a screwdriver should be engaged vertically with the tool engaging portion of the small gear. In some cases, it is difficult to rotate the small gear.

また、蝶番ピンにレバーを設けてレバーを手指で上下動させて蝶番ピンを枢着部に着脱させるものもある(例えば、特許文献3参照)。しかし、これは作業空間が狭くとも対処できるものであるが、蝶番ピンを摺動させる際に摩擦力が大きいと作業が大変であった。
特許第2996626号公報 特開2002−106239公開公報 特開2000−310082公開公報
In addition, there is a hinge pin that is provided with a lever, and the lever is moved up and down with fingers to attach and detach the hinge pin to and from the pivoting portion (for example, see Patent Document 3). However, this can be dealt with even if the working space is small, but the work is difficult if the frictional force is large when sliding the hinge pin.
Japanese Patent No. 29996626 Japanese Patent Laid-Open No. 2002-106239 Japanese Unexamined Patent Publication No. 2000-310082

本発明は前記のような従来の問題点を解決して、工具を使用せず容易に場所とることなく蝶番ピンを着脱できる蝶番を提供することである。   The present invention solves the above-described conventional problems and provides a hinge that can be attached and detached without using a tool and without taking up space easily.

本発明の蝶番は、ボックス本体又は扉のどちらか一方に取り付ける蝶番本体のピン軸受管部に上下動自在に嵌挿した蝶番ピンの先端部を蝶番本体に軸支した支軸部を起点に起伏させるレバーにより扉又はボックス本体のどちらか一方に設けたピンホルダーに嵌合自在としたことを特徴とするものを基本の発明とする。   The hinge of the present invention is undulated starting from a support shaft part that pivotally supports the tip of a hinge pin fitted to the pin bearing tube part of the hinge body attached to either the box body or the door in a vertically movable manner. A basic invention is characterized in that the lever can be fitted to a pin holder provided on either the door or the box body.

この発明において、蝶番ピンの軸部にラックを形成して該ラックに噛合する小歯車をレバーの支軸部に形成させることが好ましい。また、蝶番ピンの軸部の頭部に凹部を形成して該凹部に係合する突起をレバーに形成することがより好ましいものである。   In the present invention, it is preferable to form a rack on the shaft portion of the hinge pin and to form a small gear that meshes with the rack on the support shaft portion of the lever. Further, it is more preferable that a recess is formed in the head portion of the shaft portion of the hinge pin, and a protrusion engaging with the recess is formed on the lever.

前記した本発明の蝶番は、例えば、ボックス本体に蝶番本体を取り付け、扉にピンホルダーを取り付ければ、蝶番本体はピン軸受管部に上下動自在に嵌挿した蝶番ピンの先端部を蝶番本体に軸支した支軸部を支点に起伏させるレバーによりピンホルダーに嵌合自在としたものであるから、工具を使用せず手指によるレバーの操作により蝶番ピンの先端部をピンホルダーに軸支させれば扉はボックス本体に開閉自在に取り付けられることになる。   In the hinge of the present invention described above, for example, when the hinge body is attached to the box body and the pin holder is attached to the door, the hinge body is attached to the pin body of the hinge shaft so that the hinge pin can be moved up and down. Since the pivoting support shaft part can be freely fitted to the pin holder by a lever that moves up and down around the fulcrum, the tip of the hinge pin can be pivotally supported on the pin holder by operating the lever with your fingers without using a tool. In this case, the door is attached to the box body so as to be freely opened and closed.

このように開閉自在に取り付けた扉が、ボックス本体内に電気・電子機器類の設置工事等において邪魔となる場合には、レバーを操作して蝶番ピンの先端部のピンホルダーへの軸支を解除することにより容易に行うことがきる。この場合にレバーは蝶番本体に軸支した支軸部を支点に起伏させるものであるので工具を使用せず手指による小さな力で容易に操作できるものである。また、再度扉を取り付ける作業も工具を使用せず手指により容易なものである。     If the door that can be freely opened and closed in this way interferes with the installation work of electrical and electronic equipment in the box body, the lever is operated to pivotally support the tip of the hinge pin to the pin holder. It can be done easily by releasing. In this case, since the lever undulates at the fulcrum the pivot portion that is pivotally supported on the hinge body, the lever can be easily operated with a small force with a finger without using a tool. Moreover, the operation | work which attaches a door again is also easy with a finger | toe, without using a tool.

また、蝶番ピンの軸部にラックを形成して該ラックに噛合する小歯車をレバーの支軸部に形成させたものにあっては、より小さな力によりレバーの操作ができるものである。さらに、蝶番ピンの軸部の頭部に凹部を形成して、該凹部に係合する突起をレバーに形成したものとすれば、輸送時の振動や不慮の外力に対してレバーが回動することなく、意図せず蝶番ピンが外れるのを確実に防止できるものである。     Further, in a case where a rack is formed on the shaft portion of the hinge pin and a small gear meshing with the rack is formed on the support shaft portion of the lever, the lever can be operated with a smaller force. Furthermore, if a recess is formed in the head portion of the shaft portion of the hinge pin and a protrusion that engages with the recess is formed on the lever, the lever rotates with respect to vibration during transportation and unexpected external force. Without unintentionally, the hinge pin can be reliably prevented from coming off.

次に、本発明の好ましい実施形態を図に基づき説明する。
〔第1の実施形態〕
先ず、図1〜図13に示す第1の実施形態につき説明する。
1はボックス本体100又は扉101のどちらか一方に取り付ける蝶番本体であり、本実施形態ではボックス本体100に取り付けられている。この蝶番本体1は、取付板部11の側縁に折曲形成した側板部12の先端から前記取付板部11に平行に連設したピン軸支持板部13の先端にピン軸受管部1aを形成したものである。そして、ピン軸受管部1aには上下動自在に蝶番ピン2が嵌挿されている。
Next, a preferred embodiment of the present invention will be described with reference to the drawings.
[First Embodiment]
First, the first embodiment shown in FIGS. 1 to 13 will be described.
A hinge body 1 is attached to either the box body 100 or the door 101, and is attached to the box body 100 in this embodiment. The hinge main body 1 has a pin bearing tube portion 1a at a tip end of a pin shaft support plate portion 13 connected in parallel to the attachment plate portion 11 from a tip end of a side plate portion 12 bent at a side edge of the attachment plate portion 11. Formed. A hinge pin 2 is fitted into the pin bearing tube portion 1a so as to be movable up and down.

蝶番ピン2は、蝶番本体1に軸支した支軸部31を起点に起伏させるレバー3によりその先端部2aをピン軸受管部1aより出没自在として、扉101又はボックス本体100のどちらか一方に取り付けるピンホルダー4に嵌合自在とされている。本実施形態ではピンホルダー4は扉101に取り付けられている。     The hinge pin 2 is provided at either the door 101 or the box body 100 so that its tip 2a can be protruded and retracted from the pin bearing tube 1a by a lever 3 that moves up and down from a support shaft 31 pivotally supported on the hinge body 1. It can be freely fitted to the pin holder 4 to be attached. In this embodiment, the pin holder 4 is attached to the door 101.

この実施形態においては図3〜図6に示すように、蝶番ピン2の先端部2aをピン軸受管部1aより出没自在とするレバー3は、支軸部31に小歯車31aを形成して蝶番ピン2の軸部21に設けたラック21aと噛合させたものである。これにより、レバー3を支軸部31を起点に起伏させれば小歯車31aが回動してこれに噛合しているラック21aにより蝶番ピン2はその先端部2aをピン軸受管部1aより出没自在としてピンホルダー4に嵌合自在となるものである。また、レバー3は本体部3aに対し略90度に折り曲げた取手部3bを有し、取手部3bの裏面には、蝶番ピン2の頭部に形成した凹部2cに係合する突起3cが設けられている。     In this embodiment, as shown in FIGS. 3 to 6, the lever 3 that allows the tip 2 a of the hinge pin 2 to protrude and retract from the pin bearing tube 1 a is formed by forming a small gear 31 a on the support shaft 31. This is engaged with a rack 21 a provided on the shaft portion 21 of the pin 2. As a result, when the lever 3 is raised and lowered with the support shaft portion 31 as a starting point, the small gear 31a rotates and the hinge pin 2 protrudes and retracts from the pin bearing tube portion 1a by the rack 21a meshing with the rack 21a. The pin holder 4 can be freely fitted freely. The lever 3 has a handle portion 3b bent at about 90 degrees with respect to the main body portion 3a, and a protrusion 3c that engages with a recess 2c formed on the head of the hinge pin 2 is provided on the back surface of the handle portion 3b. It has been.

なお、蝶番本体1はピンホルダー4を上に載せて扉101の重量を支えるものにあっては、図1―図6に示すように蝶番ピン2の先端部2aをレバー3により上向きに出没自在としている。また、扉101が上方に移動するのを規制するために蝶番本体1がピンホルダー4の上部に位置するものにあっては、図7―図9に示すように蝶番ピン2の先端部2aをレバー3により下向きに出没自在としている。   When the hinge body 1 has a pin holder 4 placed on it to support the weight of the door 101, the tip 2a of the hinge pin 2 can be moved up and down by the lever 3 as shown in FIGS. It is said. Further, in the case where the hinge body 1 is positioned above the pin holder 4 in order to restrict the upward movement of the door 101, the tip 2a of the hinge pin 2 is attached as shown in FIGS. The lever 3 can be moved in and out downward.

また、前記ピンホルダー4は断面L字状の本体41の上下に孔42aを透設した上下板部42、42を設けたもので、蝶番ピン2の先端部2aが上向き下向きの何れの方向にも出没自在なものにも対応できるものとしている。なお、ピンホルダー4はこれに限ることなく筒状に形成したものでもよい。   Further, the pin holder 4 is provided with upper and lower plate portions 42, 42 having holes 42a formed in the upper and lower sides of a main body 41 having an L-shaped cross section, and the distal end portion 2a of the hinge pin 2 is directed upward and downward. It is also possible to handle anything that can freely appear and disappear. The pin holder 4 is not limited to this and may be formed in a cylindrical shape.

このように構成されたものは、図10、図11に示すようにボックス本体100に蝶番本体1を上下に複数個すなわち上部のものは蝶番ピン2を下向きに出没自在としたものを中間及び下部のものは蝶番ピン2を上向きに出没自在としたものを3個取り付け、扉101には同じく3個のピンホルダー4を取り付けて、図2、図7及び図11に示すように蝶番本体1のレバー3を蝶番ピン2の先端がピン軸受管部1aに没入した状態すなわち、この実施形態ではレバー3の取手部3bを蝶番ピン2の先端側に移動させる。そして、扉101に取り付けたピンホルダー4がピン軸受管部1aの先端に臨む位置になるように扉101を移動させて、その後にレバー3を工具を使用せず手指により操作して該レバー3の支軸部31を回動させれば小歯車31aと噛合っているラック21aにより蝶番ピン2の先端部2aがピン軸受管部1aより張出してピンホルダー4に嵌合して蝶番が連結されて扉101は図12、図13に示すようにボックス本体100に開閉自在に取り付けられることとなる。さらに、図9に示すように、蝶番ピンの頭部に形成した凹部2cとレバー3の突起3cとを係合させることにより、不慮の外力等が働いてもレバー3が回動することを防止することを可能にできるものである。     As shown in FIGS. 10 and 11, a plurality of hinge bodies 1 are vertically arranged on the box body 100, that is, the upper one is configured such that the hinge pin 2 can be protruded and lowered downward. As shown in FIGS. 2, 7, and 11, three hinges 2 having hinge pins 2 that can be moved upward and downward are attached, and three pin holders 4 are also attached to the door 101. As shown in FIGS. In the lever 3, the tip of the hinge pin 2 is immersed in the pin bearing tube portion 1 a, that is, in this embodiment, the handle 3 b of the lever 3 is moved to the tip of the hinge pin 2. Then, the door 101 is moved so that the pin holder 4 attached to the door 101 faces the tip of the pin bearing tube portion 1a, and then the lever 3 is operated with fingers without using a tool to operate the lever 3 When the support shaft portion 31 is rotated, the tip end portion 2a of the hinge pin 2 extends from the pin bearing tube portion 1a by the rack 21a meshing with the small gear 31a, and the hinge is connected by being fitted to the pin holder 4. The door 101 is attached to the box body 100 so as to be opened and closed as shown in FIGS. Further, as shown in FIG. 9, by engaging the recess 2c formed on the head of the hinge pin and the projection 3c of the lever 3, the lever 3 is prevented from rotating even if an unexpected external force is applied. It is possible to do that.

そして、扉101がボックス本体100内に電気電子機器類の設置工事等において邪魔となる場合には、工具を使用せず手指によりレバー3を逆方向に操作して小歯車31aを逆回動させて噛合っているラック21aにより蝶番ピン2の先端部2aをピン軸受管部1aに没入させてピンホルダー4への軸支を解除することにより容易に行うことがきる。この場合にレバー3は蝶番本体1に軸支した支軸部31を起点に起伏させるものであるので小さな力で容易に操作できるものである。また、再度扉を取り付ける作業も工具を使用せず手指により容易に行えるものである。     If the door 101 becomes an obstacle in the installation work of electric and electronic devices in the box body 100, the lever 3 is operated in the reverse direction with fingers without using a tool, and the small gear 31a is rotated in the reverse direction. This can be easily performed by immersing the tip 2a of the hinge pin 2 in the pin bearing tube 1a by the rack 21a meshing with each other to release the shaft support to the pin holder 4. In this case, the lever 3 can be easily operated with a small force because the lever 3 is raised and lowered with the support shaft portion 31 pivotally supported on the hinge body 1 as a starting point. Further, the operation of attaching the door again can be easily performed with fingers without using a tool.

〔第2の実施形態〕
続いて、図14―図16に示す第2の実施形態につき説明する。
この実施形態は、蝶番本体1が取付板部11の側縁に折曲形成した側板部12の先端から前記取付板部11に平行に連設したピン軸支持板部13の先端にピン軸受管部1aを形成したものであって、ピン軸受管部1aには上下動自在に蝶番ピン2が嵌挿されており、さらに、蝶番ピン2が蝶番本体1に軸支した支軸部を起点に起伏させるレバー3によりその先端部2aをピン軸受管部1aより出没自在として、ピンホルダー4に嵌合自在とされるものであることは前記第1の実施形態と同様である。
[Second Embodiment]
Next, a second embodiment shown in FIGS. 14 to 16 will be described.
In this embodiment, the hinge body 1 is bent at the side edge of the mounting plate portion 11 from the tip of the side plate portion 12 to the tip of the pin shaft support plate portion 13 provided in parallel to the mounting plate portion 11. A hinge pin 2 is fitted into the pin bearing tube portion 1a so as to be movable up and down, and the hinge pin 2 is pivotally supported on the hinge body 1 as a starting point. As in the first embodiment, the lever 3 that moves up and down allows the tip end 2a to be protruded and retracted from the pin bearing tube portion 1a and can be fitted into the pin holder 4.

しかしながら、この実施形態のものは、蝶番ピン2が蝶番本体1に軸支した支軸部を起点に起伏させるレバー3によりその先端部2aをピン軸受管部1aより出没自在とする具体的手段が相違するものである。すなわち、レバー3は中間部を支軸部である軸ピン33により蝶番本体1に軸支して先端部に設けた長孔34に、ピン軸受管部1aに透設した上下方向の長孔1bから突出させた蝶番ピン2の腕部22を遊嵌したものである。     However, in this embodiment, there is a specific means for allowing the tip 2a to protrude and retract from the pin bearing tube portion 1a by a lever 3 that raises and lowers from a support shaft portion in which the hinge pin 2 is pivotally supported by the hinge body 1. It is different. That is, the lever 3 is supported by a shaft pin 33 which is a support shaft portion at an intermediate portion thereof and is supported by the hinge main body 1 at a long hole 34 provided at a tip portion thereof, and a vertical long hole 1b which is provided through the pin bearing tube portion 1a. The arm portion 22 of the hinge pin 2 protruded from is loosely fitted.

そして、レバー3を軸ピン33を支点に起伏させればレバー3の先端部が上下動してこれに伴ない該先端部の長孔34に遊嵌されている蝶番ピン2の腕部22がピン軸受管部1aに透設した上下方向の長孔1b内を上下動して腕部22を突設した蝶番ピン2も上下動して蝶番ピン2の先端部2aがピン軸受管部1aより出没してピンホルダー4に嵌合自在となり、蝶番を容易に連結・分離して扉101のボックス本体100の着脱を容易に行うことができるものであるうえ、第1の実施形態のような蝶番ピン2のラックや該ラックに噛合する小歯車を設ける必要がないので製造コストを安くすることができるものである。     When the lever 3 is raised and lowered with the shaft pin 33 as a fulcrum, the tip portion of the lever 3 moves up and down, and the arm portion 22 of the hinge pin 2 that is loosely fitted in the elongated hole 34 of the tip portion accordingly. The hinge pin 2 that moves up and down in the vertically elongated hole 1b that is provided in the pin bearing tube portion 1a to project the arm portion 22 also moves up and down, and the tip 2a of the hinge pin 2 is moved from the pin bearing tube portion 1a. The hinge can be inserted into and retracted from the pin holder 4, and the hinge can be easily connected and separated to easily attach and detach the box body 100 of the door 101, and the hinge as in the first embodiment. Since it is not necessary to provide a rack of pins 2 or a small gear meshing with the rack, the manufacturing cost can be reduced.

また、この実施形態おいても第1の実施形態と同様に、レバー3の取手部3bの裏面には、蝶番ピン2の頭部に形成した凹部2cと係合する突起3cが設けられていて、不慮の外力等が働いてもレバー3が回動することを防止できるものが好ましい。なお、その他の構成及び作用は第1の実施形態と同様であるのでその説明を援用する。また、図示の蝶番本体1は蝶番ピン2の先端部2をレバー3により下向きに出没自在としているが、蝶番ピン2の先端部2aをレバー3により上向きに出没自在としたものを採用することは勿論である     Also in this embodiment, as in the first embodiment, the back surface of the handle portion 3b of the lever 3 is provided with a projection 3c that engages with a recess 2c formed on the head of the hinge pin 2. It is preferable that the lever 3 can be prevented from rotating even if an unexpected external force is applied. Since other configurations and operations are the same as those of the first embodiment, the description thereof is incorporated. Further, the hinge body 1 shown in the figure has the tip 2 of the hinge pin 2 freely projecting and retracting downward by the lever 3, but adopting the hinge pin 2 having the tip 2 a of the hinge pin 2 freely projecting and retracting upward by the lever 3 is possible.
