At least one of the first bearing part 3a and the second bearing part is provided with a horizontal wear preventing cover 20 made of material softer than the material of the horizontal hinge shaft 10 to cover the one end 11 or the other end 12 of the horizontal hinge shaft 10 and to prevent the wear of at least one of the first bearing part 3a and the second bearing part.

Description

本発明は、一方の筐体が他方の筐体に対して折畳み又は表裏反転可能に連結された携帯端末に関するものである。   The present invention relates to a portable terminal in which one casing is connected to the other casing so that the casing can be folded or reversed.

従来より、第１の筐体と第２の筐体とがヒンジ部を介して折畳み開閉可能に連結された携帯端末は知られている。このような携帯端末が通信機能を有する場合、電波のシールドの問題から、その筐体は主にプラスチックで構成されることが知られている。   2. Description of the Related Art Conventionally, a portable terminal in which a first housing and a second housing are connected via a hinge portion so as to be folded and opened is known. When such a portable terminal has a communication function, it is known that its housing is mainly made of plastic due to the problem of shielding radio waves.

ヒンジ部は、折畳み操作を繰り返すため、ヒンジ部の軸部分には金属部品が用いられる。このため、強度の高い軸部分によって、それよりも強度の低い樹脂製の軸受部分が削られるという問題がある。軸受部分が削られると、軸部分の周囲に隙間が発生し、開閉機能が阻害されてしまう。また、摩耗防止等のために軸部分には各種潤滑剤を塗布してから挿入することが行われている。   Since the hinge portion repeats the folding operation, a metal part is used for the shaft portion of the hinge portion. For this reason, there exists a problem that the resin-made bearing part with lower intensity | strength is shaved by the shaft part with high intensity | strength. When the bearing portion is cut, a gap is generated around the shaft portion and the opening / closing function is hindered. In order to prevent wear and the like, various types of lubricant are applied to the shaft portion and then inserted.

そこで、例えば特許文献１のプラスチック製ハウジングは、第１ハウジングと第２ハウジングとを回転ヒンジ部を介して折畳み開閉可能に接続し、プラスチックで成形された第１、第２ハウジングのそれぞれ一端部に一体に互いに隣接して嵌合するプラスチックで成形された第１軸受及び第２軸受と、これら第１及び第２軸受の軸孔内に軸方向に沿って設けた突起状リブとを備えた軸受部に、金属製の支軸に回転可能に軸支された外周に溝状リブを設けた第１回転体及び第２回転体と、これら第１、第２回転体を互いに支軸を中心に相対的に所定の回転角度差を持つ位置にて一旦停止ロックさせるクリック機構とを備えた支軸部を嵌挿した折畳みヒンジ部を備え、第２回転体を嵌挿した第２軸受の軸孔内に、そのプラスチック製の軸孔内周面と突起状リブを保護する形状の保護キャップが装填されている折畳みヒンジ部を備えている。   Therefore, for example, in the plastic housing of Patent Document 1, the first housing and the second housing are connected so as to be foldable and openable via a rotary hinge portion, and are respectively attached to one end portions of the first and second housings molded of plastic. A bearing comprising a first bearing and a second bearing formed of plastic that are integrally fitted adjacent to each other, and projecting ribs provided along the axial direction in the shaft holes of the first and second bearings. The first rotating body and the second rotating body provided with groove-shaped ribs on the outer periphery thereof rotatably supported by a metal supporting shaft, and the first and second rotating bodies are mutually centered on the supporting shaft. A shaft hole of a second bearing having a folding hinge portion into which a support shaft portion having a click mechanism for temporarily stopping and locking at a position having a relatively predetermined rotation angle difference is inserted and into which a second rotating body is inserted. Inside the plastic shaft hole inner peripheral surface Protective cap shaped to protect the protruding rib is provided with a folding hinge portion is loaded.

しかしながら、上記特許文献１の携帯端末では、ヒンジ軸自体もプラスチック製であるので、耐久性の面で問題がある上、汎用性が低くて入手が難しい。   However, since the hinge shaft itself is made of plastic, the portable terminal of Patent Document 1 has problems in terms of durability and is difficult to obtain due to low versatility.

そこで、従来の金属製のヒンジ軸を用いながらも、樹脂製の軸受部が損傷しないようにしたい、というニーズがある。   Therefore, there is a need to prevent damage to the resin bearing while using a conventional metal hinge shaft.

本発明は、かかる点に鑑みてなされたものであり、その目的とするところは、汎用性のある金属製のヒンジ軸を使用しながら、潤滑剤を塗布することなく簡単に挿入でき、かつ軸受周辺の耐久性を向上させることにある。   The present invention has been made in view of the above points, and the object of the present invention is to use a versatile metal hinge shaft and easily insert it without applying a lubricant, and a bearing. The purpose is to improve the durability of the surrounding area.

上記の目的を達成するために、この発明では、金属製のヒンジ軸の一部のみをヒンジ軸よりも柔らかい材料で覆うようにした。   In order to achieve the above object, in the present invention, only a part of the metal hinge shaft is covered with a material softer than the hinge shaft.

具体的には、第１の発明は、第１の筐体と第２の筐体とがヒンジ部を介して折畳み開閉可能に連結された携帯端末を前提とし、
そして、上記ヒンジ部は、
上記第１の筐体と上記第２の筐体とを相対的に回転可能に連結する金属製の水平ヒンジ軸と、
上記第１の筐体に設けられて上記水平ヒンジ軸の一端が連結される第１軸受部と、
上記第２の筐体に設けられて上記水平ヒンジ軸の他端が連結される第２軸受部と、
上記水平ヒンジ軸の一端又は他端を覆うと共に、上記水平ヒンジ軸よりも柔らかい材質よりなり、上記第１軸受部又は上記第２軸受部に嵌合されて該第１軸受部又は上記第２軸受部の摩耗を防止する水平摩耗防止用カバーとを備えている。 Specifically, the first invention presupposes a portable terminal in which a first housing and a second housing are connected to each other via a hinge part so as to be foldable and openable.
And the hinge part is
A horizontal hinge shaft made of metal that connects the first housing and the second housing in a relatively rotatable manner;
A first bearing portion provided in the first housing and connected to one end of the horizontal hinge shaft;
A second bearing portion provided in the second housing and connected to the other end of the horizontal hinge shaft;
One end or the other end of the horizontal hinge shaft is covered and made of a softer material than the horizontal hinge shaft, and is fitted to the first bearing portion or the second bearing portion so as to be fitted to the first bearing portion or the second bearing. And a horizontal wear prevention cover for preventing wear of the parts.

上記の構成によると、金属製の硬い水平ヒンジ軸の少なくとも一方側を、この水平ヒンジ軸よりも柔らかい水平摩耗防止用カバーが覆っているので、この水平摩耗防止用カバーが当接する第１軸受部又は第２軸受部が摩耗せず、折畳み開閉操作が阻害されない。また、摩耗の防止等のために潤滑剤を塗布しなくてもよいので潤滑油が漏れ出さない上に塗布の手間が省ける。   According to the above configuration, since the horizontal wear prevention cover softer than the horizontal hinge shaft covers at least one side of the metal hard horizontal hinge shaft, the first bearing portion with which the horizontal wear prevention cover abuts. Alternatively, the second bearing portion is not worn and the folding opening / closing operation is not hindered. Further, since it is not necessary to apply a lubricant to prevent wear, the lubricating oil does not leak out, and the labor of application can be saved.

第２の発明では、回転側筐体が固定側筐体に対してヒンジ部を介して表裏反転可能に連結された携帯端末を前提とする。   In 2nd invention, the rotation side housing | casing presupposes the portable terminal connected with the fixed side housing | casing through the hinge part so that front-back inversion was possible.

そして、上記ヒンジ部は、
上記回転側筐体を回転可能に上記固定側筐体に連結する金属製の垂直ヒンジ軸と、
上記垂直ヒンジ軸の一端が連結される垂直軸受部と、
上記垂直ヒンジ軸の一端の少なくとも一部を覆うと共に、該垂直ヒンジ軸よりも柔らかい材質よりなり、上記垂直軸受部に当接して該垂直軸受部の摩耗を防止する垂直摩耗防止用カバーとを備えている。 And the hinge part is
A metal vertical hinge shaft that rotatably connects the rotation-side housing to the fixed-side housing;
A vertical bearing portion to which one end of the vertical hinge shaft is coupled;
A vertical wear prevention cover that covers at least a part of one end of the vertical hinge shaft and is made of a material softer than the vertical hinge shaft and prevents wear of the vertical bearing portion by contacting the vertical bearing portion; ing.

上記の構成によると、金属製の硬い垂直ヒンジ軸の一端の少なくとも一部を、この垂直ヒンジ軸よりも柔らかい垂直摩耗防止用カバーが覆っているので、この垂直摩耗防止用カバーが当接する垂直軸受部が摩耗せず、回転操作が阻害されない。また、摩耗の防止等のために潤滑剤を塗布しなくてもよいので潤滑油が漏れ出さない上に塗布の手間が省ける。   According to the above configuration, at least a part of one end of the metal hard vertical hinge shaft is covered with the vertical wear prevention cover that is softer than the vertical hinge shaft. The parts do not wear and the rotation operation is not hindered. Further, since it is not necessary to apply a lubricant to prevent wear, the lubricating oil does not leak out, and the labor of application can be saved.

第３の発明では、第１又は第２の発明において、
上記水平摩耗防止用カバー又は垂直摩耗防止用カバーは、上記水平ヒンジ軸又は垂直ヒンジ軸に一体成形された樹脂成形品である。 In the third invention, in the first or second invention,
The horizontal wear prevention cover or the vertical wear prevention cover is a resin molded product integrally formed on the horizontal hinge shaft or the vertical hinge shaft.

上記の構成によると、樹脂成形品であれば、インサート成形などにより、金属製の水平ヒンジ軸又は垂直ヒンジ軸と一体成形できるので、成形が容易であると共に、樹脂部分と金属部分とが密着するので、両者間で摩耗が生じにくい。   According to the above configuration, if it is a resin molded product, it can be integrally formed with a metal horizontal hinge shaft or vertical hinge shaft by insert molding or the like, so that molding is easy and the resin portion and the metal portion are in close contact with each other. Therefore, wear is less likely to occur between the two.

第４の発明では、第１又は第２の発明において、
上記水平摩耗防止用カバー又は垂直摩耗防止用カバーは、上記水平ヒンジ軸又は垂直ヒンジ軸に該水平ヒンジ軸又は垂直ヒンジ軸を構成する金属よりも柔らかい金属でメッキされて形成されている。 In the fourth invention, in the first or second invention,
The horizontal wear prevention cover or the vertical wear prevention cover is formed by plating the horizontal hinge shaft or the vertical hinge shaft with a metal softer than the metal constituting the horizontal hinge shaft or the vertical hinge shaft.

上記の構成によると、メッキにより水平摩耗防止用カバー又は垂直摩耗防止用カバーを容易に成形でき、また、一度メッキすれば、水平摩耗防止用カバー又は垂直摩耗防止用カバー部分が剥がれにくい。   According to the above configuration, the horizontal wear prevention cover or the vertical wear prevention cover can be easily formed by plating, and once plated, the horizontal wear prevention cover or the vertical wear prevention cover portion is hardly peeled off.

以上説明したように、本発明によれば、金属製のヒンジ軸を、このヒンジ軸よりも柔らかいカバーで覆って軸受部に嵌合又は当接させるようにしたことにより、汎用性のある金属製のヒンジ軸を使用しながら、潤滑剤を塗布することなく簡単に挿入でき、かつ軸受周辺の耐久性を向上させることができる。   As described above, according to the present invention, the metal hinge shaft is covered with a softer cover than the hinge shaft and fitted or brought into contact with the bearing portion. This hinge shaft can be used for easy insertion without applying a lubricant, and the durability around the bearing can be improved.

以下、本発明の実施形態を図面に基づいて説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings.

（実施形態１）
図２は本発明の実施形態１の携帯端末としての携帯電話機１を示し、この携帯電話機１は、表示部２を有する第１の筐体３と、操作部４を有する第２の筐体５とがヒンジ部６を介して折畳み開閉可能に連結されている。第１の筐体３及び第２の筐体５は、例えばポリカーボネイト樹脂、ＡＢＳ樹脂、ポリアミドＭＸＤ６樹脂などの樹脂成形品よりなる。 (Embodiment 1)
FIG. 2 shows a mobile phone 1 as a mobile terminal according to the first embodiment of the present invention. The mobile phone 1 includes a first housing 3 having a display unit 2 and a second housing 5 having an operation unit 4. Are connected via a hinge part 6 so as to be foldable. The 1st housing | casing 3 and the 2nd housing | casing 5 consist of resin molded products, such as polycarbonate resin, ABS resin, and polyamide MXD6 resin, for example.

そしてヒンジ部６は、図１に示すように、第１の筐体３と第２の筐体５とを回転可能に連結する金属製の水平ヒンジ軸１０を備えている。   As shown in FIG. 1, the hinge portion 6 includes a metal horizontal hinge shaft 10 that rotatably connects the first housing 3 and the second housing 5.

一方、第１の筐体３の左側下端部には、水平ヒンジ軸１０の一端１１側が連結される、ボス状の第１軸受部３ａが設けられている。なお、第１の筐体３の右側下端部には、ボス状の右側軸受部３ｂが設けられているが、この右側軸受部３ｂには、水平ヒンジ軸１０は、内蔵されていない。   On the other hand, a boss-shaped first bearing portion 3 a to which one end 11 side of the horizontal hinge shaft 10 is connected is provided at the lower left end portion of the first housing 3. A boss-shaped right bearing 3b is provided at the lower right end of the first housing 3, but the horizontal hinge shaft 10 is not built in the right bearing 3b.

一方、第２の筐体５の左右中央部には、表面上へ膨出するように、水平ヒンジ軸１０の他端１２側が連結される第２軸受部５ａが形成されている。詳しくは図示しないが、図４に示すように、水平ヒンジ軸１０の主要部品は、ステンレスなどの金属で構成され、一端１１側と、他端１２側とが、特定の角度で固定可能なように節度を持って相対的に回転可能に構成されている。また、右側軸受部３ｂと第２軸受部５ａとの間は、例えば、一方側から突出する軸状部分を他方側で受けることで回転可能に連結されている。   On the other hand, a second bearing portion 5a to which the other end 12 side of the horizontal hinge shaft 10 is connected is formed at the left and right central portion of the second housing 5 so as to bulge onto the surface. Although not shown in detail, as shown in FIG. 4, the main parts of the horizontal hinge shaft 10 are made of metal such as stainless steel, and the one end 11 side and the other end 12 side can be fixed at a specific angle. It is configured to be relatively rotatable with moderation. Further, the right bearing portion 3b and the second bearing portion 5a are rotatably connected by receiving, for example, a shaft-like portion protruding from one side on the other side.

そして、本発明の特徴として、図４に示すように、水平ヒンジ軸１０の一端１１側は、水平摩耗防止用カバー２０で覆われている。この水平摩耗防止用カバー２０は、水平ヒンジ軸１０よりも柔らかい、例えば耐摩耗性プラスチックなどの樹脂材料よりなる。水平摩耗防止用カバー２０は、インサート成形などにより、水平ヒンジ軸１０に一体に形成されている。例えば、水平ヒンジ軸１０の一端１１には、一対のカバー取付用凹部１３が形成され、このカバー取付用凹部１３に水平摩耗防止用カバー２０の係合突部２１が成形時に流れ込むことで水平摩耗防止用カバー２０が一端１１に密着している。このため、水平摩耗防止用カバー２０と一端１１との間で摩耗が発生しにくくなっている。   As a feature of the present invention, as shown in FIG. 4, the one end 11 side of the horizontal hinge shaft 10 is covered with a horizontal wear prevention cover 20. The horizontal wear prevention cover 20 is made of a resin material that is softer than the horizontal hinge shaft 10, such as wear-resistant plastic. The horizontal wear prevention cover 20 is formed integrally with the horizontal hinge shaft 10 by insert molding or the like. For example, a pair of cover mounting recesses 13 is formed at one end 11 of the horizontal hinge shaft 10, and the engagement protrusion 21 of the horizontal wear prevention cover 20 flows into the cover mounting recess 13 during molding, thereby causing horizontal wear. The prevention cover 20 is in close contact with the one end 11. For this reason, wear is less likely to occur between the horizontal wear prevention cover 20 and the one end 11.

このように水平摩耗防止用カバー２０が一体成形された水平ヒンジ軸１０は、図１に示すように、第１軸受部３ａの挿入孔３ｃに圧入される。このとき、本実施形態では、潤滑剤を塗布せずに水平摩耗防止用カバー２０ごと水平ヒンジ軸１０が挿入孔３ｃに挿入される。   As shown in FIG. 1, the horizontal hinge shaft 10 in which the horizontal wear preventing cover 20 is integrally molded is press-fitted into the insertion hole 3c of the first bearing portion 3a. At this time, in this embodiment, the horizontal hinge shaft 10 is inserted into the insertion hole 3c together with the horizontal wear prevention cover 20 without applying a lubricant.

そして、第２軸受部５ａで他端１２側を覆うようにして第１の筐体３と第２の筐体５とが連結される。連結後には、ヒンジ部６により、第１の筐体３と第２の筐体５とが折畳み開閉可能となる。   And the 1st housing | casing 3 and the 2nd housing | casing 5 are connected so that the other end 12 side may be covered with the 2nd bearing part 5a. After the connection, the first housing 3 and the second housing 5 can be folded and opened by the hinge 6.

このように組み立てられた携帯電話機１では、折畳み開閉を繰り返し行っても、水平摩耗防止用カバー２０が嵌め込まれた第１軸受部３ａが摩耗せず、ヒンジ部６の耐久性が向上する。   In the cellular phone 1 assembled in this way, even if the folding opening / closing is repeated, the first bearing portion 3a fitted with the horizontal wear prevention cover 20 is not worn, and the durability of the hinge portion 6 is improved.

したがって、本実施形態に係る携帯電話機１によると、金属製の水平ヒンジ軸１０を、この水平ヒンジ軸１０よりも柔らかい水平摩耗防止用カバー２０で覆って第１軸受部３ａに挿入するようにしたことにより、汎用性のある金属製の水平ヒンジ軸１０を使用しながら、摩耗の防止等のために潤滑剤を塗布することなく簡単に挿入できる。また、第１軸受部３ａ周辺の耐久性を向上させることができるので、ガタツキが生じず、折畳み開閉操作をスムーズに行うことができる。   Therefore, according to the mobile phone 1 according to the present embodiment, the metal horizontal hinge shaft 10 is covered with the horizontal wear prevention cover 20 softer than the horizontal hinge shaft 10 and inserted into the first bearing portion 3a. Accordingly, the metal horizontal hinge shaft 10 having versatility can be easily inserted without applying a lubricant in order to prevent wear. Moreover, since durability around the first bearing portion 3a can be improved, rattling does not occur and the folding opening / closing operation can be performed smoothly.

（実施形態２）
図５〜図１０は本発明の実施形態２を示し、ヒンジ部１０６の構成が異なる点で上記実施形態１と異なる。なお、本実施形態では、図１〜図４と同じ部分については同じ符号を付してその詳細な説明は省略する。 (Embodiment 2)
5 to 10 show a second embodiment of the present invention, which differs from the first embodiment in that the configuration of the hinge portion 106 is different. In the present embodiment, the same portions as those in FIGS. 1 to 4 are denoted by the same reference numerals, and detailed description thereof is omitted.

本実施形態の携帯電話機１０１では、表示部２を有する回転側筐体１０３が操作部４を有する固定側筐体１０５に対してヒンジ部１０６を介して表裏反転可能に連結されている。そして、ヒンジ部１０６は、回転側筐体１０３と共に、固定側筐体１０５に対して折畳み開閉可能に連結されている。   In the mobile phone 101 according to the present embodiment, a rotation-side casing 103 having a display unit 2 is connected to a fixed-side casing 105 having an operation unit 4 through a hinge unit 106 so that the front and back sides can be reversed. The hinge unit 106 is connected to the stationary housing 105 together with the rotation housing 103 so as to be foldable.

具体的には、ヒンジ部１０６は、回転側筐体１０３を回転可能に支持するヒンジユニット１１５を備えている。ヒンジユニット１１５は、その中心に金属製の垂直ヒンジ軸１１０を備えている。垂直ヒンジ軸１１０の一端１１１がヒンジ部６側に連結され、他端１１２側が回転側筐体１０３側に連結されている。   Specifically, the hinge unit 106 includes a hinge unit 115 that rotatably supports the rotation-side housing 103. The hinge unit 115 includes a metal vertical hinge shaft 110 at the center thereof. One end 111 of the vertical hinge shaft 110 is connected to the hinge portion 6 side, and the other end 112 side is connected to the rotation side housing 103 side.

他端１１２は、回転側筐体１０３に結合するための取付部１１３を有し、そのネジ挿通孔１１３ａに図示しないビスを挿通して回転側筐体１０３に締結されるようになっている。取付部１１３も金属で構成され、他端１１２に回転一体に結合されている。   The other end 112 has an attachment portion 113 for coupling to the rotation side housing 103, and a screw (not shown) is inserted into the screw insertion hole 113 a so as to be fastened to the rotation side housing 103. The attachment portion 113 is also made of metal and is coupled to the other end 112 in a rotationally integrated manner.

一端１１１は、鍔を有し、その鍔の一部が他の部分よりも大きく膨出して回り止め部１１１ａを構成している。この回り止め部１１１ａがヒンジ部６側に固定されるヒンジ側取付部１１４に膨出形成したストッパ１１７に当接することで、垂直ヒンジ軸１１０の回転角度が規制されている。ヒンジ側取付部１１４は、ヒンジ部６に内蔵される樹脂製の被取付部１１６に連結されるようになっている。   The one end 111 has a ridge, and a part of the ridge bulges larger than the other portion to form a rotation stopper 111a. The rotation angle of the vertical hinge shaft 110 is regulated by the rotation preventing portion 111a coming into contact with a stopper 117 formed to bulge on the hinge side mounting portion 114 fixed to the hinge portion 6 side. The hinge side attachment portion 114 is connected to a resin attachment portion 116 built in the hinge portion 6.

そして、被取付部１１６の垂直軸受部１１６ａは、垂直ヒンジ軸１１０の一端１１１をその先端側から覆っている。   And the vertical bearing part 116a of the to-be-attached part 116 has covered the end 111 of the vertical hinge axis | shaft 110 from the front end side.

垂直ヒンジ軸１１０の一端１１１の回り止め部１１１ａのない外周には、垂直ヒンジ軸１１０よりも柔らかい樹脂製の垂直摩耗防止用カバー１２０が嵌合、接着等により結合されている。垂直摩耗防止用カバー１２０は、ストッパ１１７の円弧状外周面と一端１１１外周との間の隙間に配置されるので、垂直ヒンジ軸１１０の回転を阻害しない。この垂直摩耗防止用カバー１２０は、一端１１１の先端よりも若干軸方向に飛び出ることで、一端１１１に優先して垂直軸受部１１６ａの底面（図６及び図９の上側の面）に当接するようになっている。このことにより、直接金属製の一端１１１が直接接触して摩耗を防止するのを防止している。   A vertical wear-preventing cover 120 made of a resin softer than the vertical hinge shaft 110 is connected to the outer periphery of the vertical hinge shaft 110 without the rotation stop portion 111a at one end 111 by fitting, bonding or the like. Since the vertical wear prevention cover 120 is disposed in the gap between the arc-shaped outer peripheral surface of the stopper 117 and the outer periphery of the one end 111, it does not hinder the rotation of the vertical hinge shaft 110. The vertical wear prevention cover 120 protrudes slightly in the axial direction from the tip of the one end 111 so as to abut on the bottom surface (the upper surface in FIGS. 6 and 9) of the vertical bearing portion 116a in preference to the one end 111. It has become. This prevents the metal end 111 from directly contacting and preventing wear.

したがって、本実施形態においても、金属製の硬い垂直ヒンジ軸１１０の少なくとも一方側を、この垂直ヒンジ軸１１０よりも柔らかい垂直摩耗防止用カバー１２０が覆っているので、垂直軸受部１１６ａが摩耗せず、ヒンジ部１０６の耐久性が向上する。   Therefore, also in this embodiment, since the vertical wear prevention cover 120 that is softer than the vertical hinge shaft 110 covers at least one side of the metal hard vertical hinge shaft 110, the vertical bearing portion 116a is not worn. The durability of the hinge part 106 is improved.

（その他の実施形態）
本発明は、上記実施形態について、以下のような構成としてもよい。 (Other embodiments)
The present invention may be configured as follows with respect to the above embodiment.

すなわち、上記実施形態では、水平摩耗防止用カバー２０及び垂直摩耗防止用カバー１２０を樹脂で構成したが、ゴムやエラストマーで構成してもよい。   That is, in the above embodiment, the horizontal wear prevention cover 20 and the vertical wear prevention cover 120 are made of resin, but may be made of rubber or elastomer.

上記実施形態では、水平摩耗防止用カバー２０及び垂直摩耗防止用カバー１２０は、水平ヒンジ軸１０及び垂直ヒンジ軸１１０よりも柔らかい樹脂で構成したが、水平ヒンジ軸１０及び垂直ヒンジ軸１１０を構成する金属よりも柔らかい金属でメッキすることで構成してもよい。メッキ厚さは、例えば０．２ｍｍ〜０．３ｍｍとすればよい。この場合には、メッキにより水平摩耗防止用カバー２０又は垂直摩耗防止用カバー１２０を容易に成形でき、また、一度メッキすれば、水平摩耗防止用カバー２０又は垂直摩耗防止用カバー１２０部分が剥がれにくいというメリットがある。   In the above embodiment, the horizontal wear prevention cover 20 and the vertical wear prevention cover 120 are made of a softer resin than the horizontal hinge shaft 10 and the vertical hinge shaft 110, but constitute the horizontal hinge shaft 10 and the vertical hinge shaft 110. You may comprise by plating with a metal softer than a metal. The plating thickness may be, for example, 0.2 mm to 0.3 mm. In this case, the horizontal wear preventing cover 20 or the vertical wear preventing cover 120 can be easily formed by plating, and once plated, the horizontal wear preventing cover 20 or the vertical wear preventing cover 120 is difficult to peel off. There is a merit.

なお、以上の実施形態は、本質的に好ましい例示であって、本発明、その適用物や用途の範囲を制限することを意図するものではない。   In addition, the above embodiment is an essentially preferable illustration, Comprising: It does not intend restrict | limiting the range of this invention, its application thing, or a use.
