Description

本考案は、電気機器収納箱に使用する着脱式蝶番に関するものである。 The present invention relates to a detachable hinge used for an electrical equipment storage box.

従来、左右一対の羽根板の軸筒部に軸ピンを挿入して、羽根板を回動可能に連結するドア用蝶番として特許文献１のような発明が提案されており、この種の蝶番として、ボデー側蝶番１０３にピン挿入孔を有する第１の筒型軸受け部１０６とピン挿入孔１０５ａを有する第２の筒型軸受け部１０５とがドア側蝶番１０４を収納する距離以上に空間部１１を介して離間して同軸上に形成されており、この空間部１１にピン挿入孔１０４ａを有するドア側蝶番１０４を配置させ、一端に溝１０２を有する１本の蝶番ピン１０１を第１の筒型軸受け部１０６と第２の筒型軸受け部１０５に挿入してＵ型金具１０を溝１０２に嵌着させて、ボデー側蝶番とを着脱する電気機器収納箱用蝶番の構造を図７に示す。第１の筒型軸受け部１０６と第２の筒型軸受け部１０５との中心径を手探りで合わせた状態でドアを保持し蝶番ピン１０１をボデー側蝶番１０３とドア側蝶番１０４を貫通するまで挿入し回転動作を実現していた。また、蝶番ピン１０１の一端に設けた溝１０２にＵ型金具１０をペンチ等の工具を用いて嵌着させ、蝶番ピン１０１の抜け止めをしていた。また、電気機器収納箱のドアに穴加工等の二次的加工を施す必要がある際は、Ｕ型金具１０をペンチ等の工具を利用して引き抜いた後、蝶番ピン１０１の引き抜く際は、三つの同軸上に並ぶドア側蝶番１０４、第１の筒型軸受け部１０６および第２の筒型軸受け部１０５が干渉しているため、ドア荷重の原因により中心軸にズレが生じ、蝶番ピン１０１に荷重ストレスがかかり、蝶番ピン１０１の一端をハンマー等で下方から上方に向けて叩いていた。 Conventionally, an invention such as Patent Document 1 has been proposed as a hinge for a door in which a shaft pin is inserted into a shaft tube portion of a pair of left and right blades and the blades are rotatably connected. The first cylindrical bearing portion 106 having a pin insertion hole in the body-side hinge 103 and the second cylindrical bearing portion 105 having a pin insertion hole 105a have a space portion 11 that is longer than the distance at which the door-side hinge 104 is accommodated. The door-side hinge 104 having the pin insertion hole 104a is disposed in the space 11 and the one hinge pin 101 having the groove 102 at one end is connected to the first cylindrical shape. FIG. 7 shows the structure of a hinge for an electrical equipment storage box that is inserted into the bearing portion 106 and the second cylindrical bearing portion 105 and the U-shaped fitting 10 is fitted into the groove 102 to attach and detach the body side hinge. Hold the door with the center diameters of the first cylindrical bearing portion 106 and the second cylindrical bearing portion 105 adjusted by hand, and insert the hinge pin 101 until it passes through the body side hinge 103 and the door side hinge 104. Then, the rotating operation was realized. Further, the U-shaped metal fitting 10 is fitted into a groove 102 provided at one end of the hinge pin 101 using a tool such as pliers to prevent the hinge pin 101 from coming off. In addition, when it is necessary to perform secondary processing such as hole processing on the door of the electrical equipment storage box, after pulling out the U-shaped bracket 10 using a tool such as pliers, when pulling out the hinge pin 101, Since the door side hinge 104, the first cylindrical bearing portion 106, and the second cylindrical bearing portion 105 that are aligned on the same axis interfere with each other, the center axis is displaced due to the door load, and the hinge pin 101 A load stress was applied to the hinge pin 101, and one end of the hinge pin 101 was hit with a hammer or the like from below to above.

以下、本考案の実施の形態について、図1〜図６に基づいて説明する。なお、この実施の形態によって本考案が限定されるものではない。 Hereinafter, embodiments of the present invention will be described with reference to FIGS. In addition, this invention is not limited by this embodiment.

図1において、電気機器収納箱はボデー１とドア２とからなり、ドア２は上下一対の蝶番で開閉される。この蝶番はドア側蝶番５とボデー側蝶番７とを有する。 In FIG. 1, the electrical equipment storage box is composed of a body 1 and a door 2, and the door 2 is opened and closed by a pair of upper and lower hinges. This hinge has a door-side hinge 5 and a body-side hinge 7.

図２において、ボデー側蝶番７はＬ状で、ピン挿入孔３ａを有する第１の筒型軸受け部３とピン挿入孔４ａを有する第２の筒型軸受け部４とがドア側蝶番５を収納する距離以上に空間部１１を介して離間して同軸上に形成されている。第２の蝶番ピン８は中間にフランジ８ｂが一端に第２の溝８ａがそれぞれ形成されており、図３に示すように、第２の蝶番ピン８は第２の筒型軸受け部４のピン挿入孔４ａに挿入して一端の第２の溝８ａを空間部１１と反対側に突出させて第２の溝８ａにＵ型金具１０を嵌着させる。 In FIG. 2, the body side hinge 7 is L-shaped, and the first cylindrical bearing portion 3 having the pin insertion hole 3a and the second cylindrical bearing portion 4 having the pin insertion hole 4a accommodate the door side hinge 5. More than the distance to be separated, it is spaced apart via the space 11 and is formed coaxially. The second hinge pin 8 is formed with a flange 8b in the middle and a second groove 8a formed at one end. As shown in FIG. 3, the second hinge pin 8 is a pin of the second cylindrical bearing portion 4. The U-shaped metal fitting 10 is fitted into the second groove 8a by inserting the second groove 8a at one end into the insertion hole 4a and projecting the second groove 8a on the opposite side to the space 11.

図３において、ドア２にはピン挿入孔５ａを有する筒型状のドア側蝶番５が固着されている。一方、ボデー１においては、第１の蝶番ピン６は一端にフランジ６ｂが他端に２条の第１の溝６ａ、６ａがそれぞれ形成されている。第１の蝶番ピン６の第１の溝６ａ、６ａに開閉自在な円筒型の蝶番ピン保持具９が空間部１１において配置するように嵌着する。開閉自在な円筒型の蝶番ピン保持具９は、図６に示すように、弾力性能を有する樹脂素材を使用したもので、形状は円筒型で蝶番ピン保持具の半円弧状の２つの内方突片９ａ、９ａを第１の蝶番ピン６にある２条の第１の溝６ａ、６ａに嵌まり込む形と合致できる寸法とし、切断両面の各平面部の一方に引掛け用突起部９ｄを設け、相対する面に引掛け用突起部９ｂを収納できる突起部収納用開口部９ｃを有する構造とすることとし、指先を交差して開閉できる支持部９ｄを有する構造とすることによって容易に蝶番ピン保持具９の着脱が可能となり、第１の蝶番ピン６にある２条の第１の溝６ａ、６ａに沿って嵌着が可能となるため、ドア２の開閉による第１の蝶番ピン６の浮き上がり防止効果を得ることができる。 In FIG. 3, a cylindrical door-side hinge 5 having a pin insertion hole 5 a is fixed to the door 2. On the other hand, in the body 1, the first hinge pin 6 has a flange 6b at one end and two first grooves 6a and 6a at the other end. A cylindrical hinge pin holder 9 that can be freely opened and closed is fitted in the first groove 6 a, 6 a of the first hinge pin 6 so as to be disposed in the space portion 11. As shown in FIG. 6, the cylindrical hinge pin holder 9 that can be freely opened and closed is made of a resin material having elasticity, and has a cylindrical shape and two inner parts of the semicircular arc shape of the hinge pin holder.

The hinge pin holder 9 can be attached and detached, and can be fitted along the two first grooves 6a and 6a of the first hinge pin 6, so that the first hinge pin by opening and closing the door 2 can be used. 6 can be obtained.

以上のように構成された上下一対の電気機器収納箱用蝶番について、図３〜図６に基づいて以下、その動作、作用を説明する。 The operation and action of the pair of upper and lower electric device storage box hinges configured as described above will be described below with reference to FIGS.

まず、図３において、ボデー側蝶番７と一体となっている第２の筒型軸受部４に第２の蝶番ピン８を挿入してＵ型金具１０を第２の蝶番ピン８の一端にある第２の溝８ａに嵌着させることにより、他端が空間部１１に配置した状態で、第２の蝶番ピン８が第２の筒型軸受部４から抜け落ちない状態に組立てる。次に、ドア２を持ち上げて、ドア側蝶番５を空間部１１に配置させてドア側蝶番５のピン挿入孔５ａに第２の蝶番ピン８を挿入することにより、ドア２をボデー１に仮取り付けを行う。 First, in FIG. 3, the second hinge pin 8 is inserted into the second cylindrical bearing portion 4 integrated with the body-side hinge 7, and the U-shaped fitting 10 is at one end of the second hinge pin 8. By fitting in the second groove 8a, the second hinge pin 8 is assembled in a state in which the second hinge pin 8 does not fall off from the second cylindrical bearing portion 4 with the other end disposed in the space portion 11. Next, the door 2 is lifted, the door-side hinge 5 is placed in the space 11, and the second hinge pin 8 is inserted into the pin insertion hole 5 a of the door-side hinge 5, so that the door 2 is temporarily attached to the body 1. Install.

次に、図４において、ドア２をボデー１に仮取り付け状態において、第１の蝶番ピン６をボデー側蝶番７と一体となっている第１の筒型軸受部３にある第１の軸受部のピン挿入孔３ａから同軸上にあるドア側蝶番５に向けて挿入することによって、ドア側蝶番５に対して上から第１の蝶番ピン６を下から第２の蝶番ピン８で挟み込む (図５参照)。 Next, in FIG. 4, when the door 2 is temporarily attached to the body 1, the first bearing portion in the first cylindrical bearing portion 3 in which the first hinge pin 6 is integrated with the body-side hinge 7. The first hinge pin 6 is sandwiched by the second hinge pin 8 from the bottom with respect to the door side hinge 5 by being inserted toward the door side hinge 5 coaxially from the pin insertion hole 3a (see FIG. 5).

このようにして、空間部１１に配置したドア側蝶番５のピン挿入孔５ａに第１の蝶番ピン６の他端と第２の蝶番ピン８の他端とを挿入してドア２をボデー１に回転可能に軸支されるが、ドア２を開閉させる際に生じるドア側蝶番５と第１の蝶番ピン６との回転摩擦力で第１の蝶番ピン６に浮き上がりが生じ、第１の蝶番ピン６が自然に抜け落ちる可能性があるため、図６に示すように、空間部１１に配置した開閉自在な円筒型の蝶番ピン保持具９で第１の蝶番ピン６の第１の溝６ａ、６ａに嵌着してドア２の開閉による第１の蝶番ピン６の浮き上がり防止効果を得ることができる。 In this way, the other end of the first hinge pin 6 and the other end of the second hinge pin 8 are inserted into the pin insertion hole 5a of the door-side hinge 5 arranged in the space 11, and the door 2 is moved to the body 1. The first hinge pin 6 is lifted by the rotational frictional force between the door side hinge 5 and the first hinge pin 6 that is generated when the door 2 is opened and closed. Since the pin 6 may come off naturally, as shown in FIG. 6, the first groove 6 a of the first hinge pin 6 can be opened and closed with a freely openable cylindrical hinge pin holder 9 disposed in the space portion 11. The effect of preventing the first hinge pin 6 from being lifted up by opening and closing the door 2 by being fitted to 6a can be obtained.

また、ボデー１からドア２を取り外すための一連の動作は、図１において指先で着脱自在な蝶番ピン保持具９を蝶番ピン６から取り除き、第２の蝶番ピン８がドア２を保持することによりドア２の回転動作の中心軸がズレないため、第１の蝶番ピン６に余分なストレスがかからずスムーズに第１の蝶番ピン６を抜き取ることができ、またドア２に固着されたドア側蝶番は、ドア２を持ち上げることによって、第２の蝶番ピン８から抜き取ることができるのでドア２を安全且つ容易に一人の作業者で取り外すことができる。その際、上記一連の動作において、第２の蝶番ピン８の一端に取り付けられているＵ型金具１０は取り外す必要がないため、ドア２を取り外す際に事前に工具等を準備する必要がなくなる。 Further, a series of operations for removing the door 2 from the body 1 is performed by removing the hinge pin holder 9 detachable with the fingertip in FIG. 1 from the hinge pin 6 and holding the door 2 by the second hinge pin 8. Since the central axis of the rotational movement of the door 2 is not displaced, the first hinge pin 6 is not subjected to excessive stress, and the first hinge pin 6 can be removed smoothly, and the door side fixed to the door 2 can be removed. The hinge can be removed from the second hinge pin 8 by lifting the door 2, so that the door 2 can be safely and easily removed by one operator. At that time, in the series of operations described above, it is not necessary to remove the U-shaped bracket 10 attached to one end of the second hinge pin 8, so that it is not necessary to prepare a tool or the like in advance when removing the door 2.
