Description

本発明は、例えば、携帯電話やノートパソコンなどの折り畳み式の電子機器に採用されるヒンジ装置、並びに折り畳み式携帯電話やノートパソコンなどのヒンジ装置を用いた電子機器に関するものである。   The present invention relates to a hinge device employed in a foldable electronic device such as a mobile phone or a notebook computer, and an electronic device using a hinge device such as a foldable mobile phone or a laptop computer.

ヒンジ装置においては、様々な要望から開閉時に回動抵抗を生じさせて所定のトルクが生じるように構成している。   The hinge device is configured so as to generate a predetermined torque by generating a rotation resistance when opening and closing due to various demands.

例えば、第一部材に対して第二部材を回動させる場合、この第二部材の自重にも抗し得る回動抵抗を生じさせることで回動させる手を放した位置で停止する所謂フリーストップが実現できる回動抵抗を生じさせたり、自重により加速して勢い良く閉じないように閉じ位置前でダンパー機能が生じるようにしたい。   For example, when the second member is rotated with respect to the first member, a so-called free stop that stops at a position where the hand to be rotated is released by generating a rotation resistance that can resist the weight of the second member. It is desirable to generate a rotation resistance that can be realized, or to generate a damper function before the closed position so that it does not close rapidly by accelerating due to its own weight.

また、ワンプッシュオープン構造のように、例えばトーションバネなどによって回動付勢を生じさせておき、係止解除用のボタンやスイッチを操作することでロックが外れて第一部材に対し第二部材が自重に抗して自動回動する構成の場合も、この自動回動速度が加速し、特に９０度以上回動するとトーションバネに自重も加わって勢いが増して開放回動する場合があり、回動開放位置（全開位置）でストッパーに突き当たったりクリック係合することで開放回動位置で急停止するような場合に大きな衝撃が生じ故障の原因となったり、耐久性に劣ったりすることが考えられるため、前記のようなダンパー機能を持たせたい。   In addition, as in the one-push open structure, for example, a rotation bias is generated by a torsion spring or the like, and the lock is released by operating a lock release button or switch. In the case of a structure that automatically rotates against its own weight, this automatic rotation speed is accelerated, especially when it rotates 90 degrees or more, its own weight is also added to the torsion spring, and there is a case where it rotates and opens. If it stops suddenly at the open rotation position by hitting the stopper at the rotation open position (full open position) or by clicking engagement, it may cause a big impact and may be inferior in durability. Because it is possible, I would like to have the damper function as described above.

特に、携帯電話など手で持ってこの開閉操作を行う場合、この勢いある開放回動による慣性や、ストッパーやクリック係合による急停止によって手から落としたり落としそうになったりする場合もあり、このような問題を解決するためにも回動開放位置前の範囲で大きな回動抵抗（ブレーキ）によって減速するように構成することが望ましい。   In particular, when performing this opening and closing operation with a hand such as a mobile phone, it may be dropped or dropped from the hand due to inertia due to this momentary opening rotation or sudden stop due to a stopper or click engagement, In order to solve such a problem, it is desirable that the vehicle is decelerated by a large rotation resistance (brake) in the range before the rotation release position.

従来、このような要求や前記問題を解決するために回動抵抗を生じさせる方法としては、オイルダンパーを設けたり、回動軸部を例えばＣ状の軸受部で圧着抱持し大きな回動抵抗を生じさせたり、所定回動位置で凹凸係合するクリック係合機構を設け、一方のカム係合部にカム部が相対回動して凹凸係合させるように構成し、このカム部をカム係合部に係合付勢するカム係合用のバネを強力にしたり、擦り合わせ面での回動抵抗を大きくするなどの手段が提案されている（例えば、特許文献１参照。）。   Conventionally, in order to solve such a demand and the above-mentioned problem, as a method of generating a rotation resistance, an oil damper is provided or a rotation shaft portion is crimped and held by, for example, a C-shaped bearing portion, and a large rotation resistance is provided. Or a click engagement mechanism that engages with a concave and convex portion at a predetermined rotational position, and the cam portion is configured to rotate relative to one cam engaging portion to engage with the concave and convex portions. Means have been proposed in which the cam engagement spring that engages and urges the engagement portion is strengthened, and the rotational resistance on the rubbing surface is increased (for example, see Patent Document 1).

好適と考える本発明の実施形態（発明をどのように実施するか）を、図面に基づいて本発明の作用を示して簡単に説明する。 DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention that are considered suitable (how to carry out the invention) will be briefly described with reference to the drawings, illustrating the operation of the present invention .

第一部材１に対して第二部材２を回動すると、軸受部３に対して回動軸部４が回動するが、この際、第一部材１に対する第二部材２の所定の回動範囲では、押圧機構７が圧接体６を押圧して圧接体６が回動軸部４に被嵌状態に設けた摩擦体５を押圧変形させ、この押圧変形した摩擦体５が前記回動軸部４に圧接して摩擦体５と回動軸部４との摩擦抵抗が増大する。 When the second member 2 is rotated with respect to the first member 1, the rotation shaft portion 4 is rotated with respect to the bearing portion 3. At this time, the predetermined rotation of the second member 2 with respect to the first member 1 is performed. In the range, the pressing mechanism 7 presses the pressure contact body 6, and the pressure contact body 6 press-deforms the friction body 5 provided in the fitted state on the rotation shaft portion 4, and the press-deformed friction body 5 is the rotation shaft. The frictional resistance between the friction body 5 and the rotating shaft portion 4 increases due to pressure contact with the portion 4.

また、この際、圧接体６は前記第二部材２若しくは前記第一部材１と共に回動するが、この圧接体６が摩擦体５に圧接していることで摩擦体５と圧接体６との摩擦抵抗も増大する。   At this time, the pressure contact body 6 rotates together with the second member 2 or the first member 1, and the pressure contact body 6 is in pressure contact with the friction body 5 so that the friction body 5 and the pressure contact body 6 are in contact with each other. The frictional resistance also increases.

そのため、この回動軸部４にも圧接体６にも圧接して摩擦抵抗を生じている摩擦体５により、回動軸部４に摩擦回動抵抗が付与されることになる。   For this reason, the frictional rotation resistance is applied to the rotation shaft portion 4 by the friction body 5 that is brought into contact with the rotation shaft portion 4 and the pressure contact body 6 to generate a frictional resistance.

従って、押圧機構７が圧接体６を押圧する回動位置を設定すれば、回動抵抗が生じる位置や回動範囲を所望したように設定できる。   Therefore, if the rotation position where the pressing mechanism 7 presses the pressure contact body 6 is set, the position and rotation range where the rotation resistance is generated can be set as desired.

このように本発明は、所定の回動範囲で回動抵抗を生じさせることが容易に実現可能で、例えば、第一部材１と第二部材２とを本ヒンジ装置Ｈで枢着し、第一部材１に重合した第二部材２を重合閉塞状態から起伏回動して回動開放位置まで開放回動し得るように構成した場合に、この第一部材１に対して第二部材２が９０度以上開放回動して開放回動する部材の自重が加わってあるいは回動付勢によって勢い良く開こうとする回動範囲で摩擦抵抗（回動抵抗）を生じさせて開放回動位置へと到達する際の勢いを減速させてゆっくりと開くような、扱い易い動きを実現できる。   As described above, the present invention can easily realize the rotation resistance within a predetermined rotation range. For example, the first member 1 and the second member 2 are pivotally attached by the hinge device H, and When the second member 2 superposed on the one member 1 is configured so that it can be swung up and down from the superposition closed state to the rotational open position, the second member 2 is in relation to the first member 1. A frictional resistance (rotation resistance) is generated in a rotation range in which the weight of the member that opens and rotates 90 degrees or more and opens and rotates or is vigorously opened by the rotation bias is moved to the open rotation position. It is possible to realize easy-to-handle movements such as slowing down the momentum when reaching and opening slowly.

また、本発明は、回動軸部４に被嵌状態に設けたＣ状若しくはＯ状の摩擦体５を押圧変形させることで摩擦回動抵抗を得る簡易構造のため、簡易に設計実現可能であり、しかも、オイル式のダンパー装置を採用して回動抵抗機構を構成するような場合と異なり、故障時にオイル漏れのような不都合を生じることがなく、非常に実用的である。 In addition, the present invention is a simple structure that obtains frictional rotation resistance by pressing and deforming a C-shaped or O-shaped friction body 5 provided in a state of being fitted to the rotation shaft portion 4, so that the design can be easily realized. In addition, unlike the case where an oil-type damper device is used to configure the rotation resistance mechanism, there is no inconvenience such as oil leakage at the time of failure, and it is very practical .

また、このクリック係合機構Ｋは、回動軸部４を軸受する軸受部３に設けている。   The click engagement mechanism K is provided in the bearing portion 3 that bears the rotating shaft portion 4.

具体的には、軸受部３は、図３に示すように第一部材１の取付孔13に回り止め状態に挿入固定して回動軸部４を軸支するケース体14に、軸受孔11Ａを備えたカム係合部11をこのケース体14に回り止め状態にして設けると共に、このカム係合部11の軸受孔11Ａに回動軸部４を通してこのカム係合部11をケース体14内で回動軸部４に沿ってスライド移動自在に設けた構成としている。   Specifically, as shown in FIG. 3, the bearing portion 3 is inserted into and fixed to the mounting hole 13 of the first member 1 in a non-rotating state and is fixed to the case body 14 that pivotally supports the rotating shaft portion 4. The cam engagement portion 11 having the cam engagement portion 11 is provided in the case body 14 so as not to rotate, and the cam engagement portion 11 is inserted into the bearing hole 11A of the cam engagement portion 11 through the rotation shaft portion 4 in the case body 14.

また、カム部10を前記回動軸部４の先端部（一端部）に一体に設けると共に、このカム部10と前記カム係合部11とを対向状態に設け、更に、回動軸部４に挿通しているカム係合部11は、ケース体14内に内装したカム係合付勢バネ15により付勢されて前記カム部10に所定回動位置で凹凸係合するように構成している。また、このカム部10を設けた回動軸部４が第二部材２に回り止めされるように構成している。   Further, the cam portion 10 is provided integrally with the tip end portion (one end portion) of the rotating shaft portion 4, the cam portion 10 and the cam engaging portion 11 are provided in an opposing state, and the rotating shaft portion 4 is further provided. The cam engaging portion 11 inserted through the cam member 10 is configured to be urged by a cam engaging urging spring 15 incorporated in the case body 14 so as to engage with the cam portion 10 at a predetermined rotational position. Yes. Further, the rotation shaft portion 4 provided with the cam portion 10 is configured to be prevented from rotating by the second member 2.

また、このカム部10とカム係合部11との凹凸係合位置は、本実施例では第二部材２に対して第一部材１が全開した位置（例えば１７０度開放回動位置）と、閉じ位置を例えば１０度すぎた１８０度位相が異なる位置とで凹凸係合するようにし、全開位置で係合クリックし、閉じ位置では凹凸係合途中となって閉じ付勢が生じるようにしている。   Further, the concave / convex engagement position between the cam portion 10 and the cam engagement portion 11 is a position at which the first member 1 is fully opened with respect to the second member 2 in this embodiment (for example, a 170-degree open rotation position), Engagement is performed at the closed position, for example, at a position where the phase is different by 180 degrees, which is too 10 degrees, and the engagement click is performed at the fully opened position, and the closed bias is generated in the middle of the uneven engagement at the closed position. .

また、本実施例のクリック係合機構Ｋは、カム部10とカム係合部11とのカム係合形状の設定により、第二部材２に対し第一部材１を４０度程開放回動したところでカム部10がカム係合部11に係合しはじめてその後は手を放してもカム係合付勢バネ15の付勢力により自動的に全開位置まで回動し、逆に閉じる時は、第二部材２に対し第一部材１を３０度程の位置まで閉じたところでカム部10がカム係合部11に係合しはじめてその後は手を放してもカム係合付勢バネ15の付勢力により自動的に閉塞位置まで回動することになる構成としている。   Further, the click engagement mechanism K of the present embodiment rotates the first member 1 by about 40 degrees with respect to the second member 2 by setting the cam engagement shape of the cam portion 10 and the cam engagement portion 11. By the way, even if the cam portion 10 starts to engage with the cam engaging portion 11 and then is released, the cam portion 10 automatically rotates to the fully open position by the biasing force of the cam engagement biasing spring 15, and when the cam portion 10 is closed, When the first member 1 is closed to the position of about 30 degrees with respect to the two members 2, the cam portion 10 begins to engage with the cam engaging portion 11, and thereafter the biasing force of the cam engaging biasing spring 15 is released even if the hand is released. Thus, it is configured to automatically rotate to the closing position.

本実施例では、この第一部材１と第二部材２とを枢着するヒンジ装置Ｈに回動抵抗機構８を設けて、開放回動時の全開位置前範囲に回動抵抗を生じさせる構成としている。   In the present embodiment, the rotation resistance mechanism 8 is provided in the hinge device H that pivotally attaches the first member 1 and the second member 2, and the rotation resistance is generated in the range before the fully open position during the opening rotation. It is said.

即ち、このクリック係合機構Ｋのカム係合付勢バネ15による係合付勢によって凹凸係合位置以外でも常に少なからず回動抵抗が生じているが、これだけでは重合部を回動させる場合の自重が回動方向に加わる９０度をすぎた回動範囲では、この自重が大きいと回動速度が許容以上となることがあるため、全開位置前ではこれとは別に新たに大きな回動抵抗を生じさせる回動抵抗機構８を備えた構成としている。   That is, the engagement bias by the cam engagement biasing spring 15 of the click engagement mechanism K always causes a rotation resistance at a position other than the concavo-convex engagement position. In the rotation range where the own weight exceeds 90 degrees, the rotation speed may exceed the allowable value if the weight is too large. The rotation resistance mechanism 8 to be generated is provided.

具体的には、前記回動軸部４の他端側の外周に弾性を有するＯ状の摩擦体５を被嵌状態に設け、この摩擦体５に対し接離移動可能な圧接体６を備えると共に、この圧接体６は前記第一部材１に回り止め状態に設け、前記第一部材１に対して前記第二部材２を回動すると、前記圧接体６を押圧して前記摩擦体５に圧接せしめる押圧機構７を備えて、第一部材１に対する第二部材２の所定の回動範囲でこの押圧機構７が圧接体６を押圧して圧接体６が摩擦体５を押圧変形させ、この押圧変形した摩擦体５が前記回動軸部４に圧接することで摩擦体５の回動軸部４への摩擦抵抗が増大してこの回動軸部４に回動抵抗を付与する回動抵抗機構８を備えている。   Specifically, an O-shaped friction body 5 having elasticity is provided on the outer periphery on the other end side of the rotating shaft portion 4 in a fitted state, and a pressure contact body 6 that can move toward and away from the friction body 5 is provided. At the same time, the pressure contact body 6 is provided in the first member 1 in a non-rotating state, and when the second member 2 is rotated with respect to the first member 1, the pressure contact body 6 is pressed against the friction body 5. There is provided a pressing mechanism 7 that presses the first member 1, the pressing mechanism 7 presses the pressing member 6 in a predetermined rotation range of the second member 2 with respect to the first member 1, and the pressing member 6 presses and deforms the friction body 5. When the friction body 5 that has been pressed and deformed is brought into pressure contact with the rotating shaft portion 4, the frictional resistance of the friction body 5 to the rotating shaft portion 4 is increased, and the rotating shaft portion 4 is given rotation resistance. A resistance mechanism 8 is provided.

更に具体的には、図４〜図６に示すように、ヒンジ装置Ｈの回動軸部４を延長した設計としてケース体14より回動軸部４の他端部の延長部４Ａを突設し、この延長部４Ａの途中部に前記摩擦体５を支承する円板状の支承部12を設け、この支承部12より延長部４Ａ先端側にゴム製のＯリングを採用した摩擦体５を三体被嵌状態にして配設している。また、最も支承部12側に位置する摩擦体５を支承部12に当接支承すると共に、各摩擦体５を互いに密接状態にして配設している。   More specifically, as shown in FIGS. 4 to 6, an extension 4 </ b> A at the other end of the pivot shaft 4 protrudes from the case body 14 as a design in which the pivot shaft 4 of the hinge device H is extended. A disc-like support portion 12 for supporting the friction body 5 is provided in the middle of the extension portion 4A, and the friction body 5 adopting a rubber O-ring is provided on the distal end side of the extension portion 4A from the support portion 12. The three-body fitting state is provided. Further, the friction body 5 located closest to the support portion 12 is in contact with and supported by the support portion 12, and the friction bodies 5 are arranged in close contact with each other.

また、この各摩擦体５の外周部を被覆し得る有底円筒状であって、底部に相当する部位に前記回動軸部４の延長部４Ａを挿通軸支する挿通孔６Ｃを有する圧接体６を、この挿通孔６Ｃと反対側の開口部を摩擦体５側に向けて延長部４Ａの先端部（他端部）から配設して挿通孔６Ｃを延長部４Ａにスライド自在に軸支することで各摩擦体５に被嵌状態にして設け、図７に示すように、この圧接体６がケース体14側に向かって移動すると、各摩擦体５がこの圧接体６と前記支承部12とにより挟持押圧されて各摩擦体５が回動軸部４の軸方向と直交する方向に圧延変形し、この際、筒状の圧接体６の周壁部６Ｄの内周面に摩擦体５の外周部が接触してこの摩擦体５の外周部が外方へと膨出変形しようとすることが阻止され（摩擦体５が外方へ逃げて回動軸部４に強く圧接しなくなることが阻止され）、これにより各摩擦体５の内径が確実に縮小するように変形して各摩擦体５の内周部が回動軸部４に圧接し摩擦抵抗を増大する構成としている。   Further, a press-contacting body having a bottomed cylindrical shape capable of covering the outer peripheral portion of each friction body 5 and having an insertion hole 6C through which the extending portion 4A of the rotating shaft portion 4 is inserted and supported at a portion corresponding to the bottom portion. 6 is disposed from the tip (the other end) of the extension 4A with the opening opposite to the insertion hole 6C facing the friction body 5, and the insertion hole 6C is slidably supported by the extension 4A. As shown in FIG. 7, when the pressure contact body 6 moves toward the case body 14 as shown in FIG. 7, each friction body 5 is connected to the pressure contact body 6 and the support portion. 12, each friction body 5 is rolled and deformed in a direction perpendicular to the axial direction of the rotation shaft portion 4. At this time, the friction body 5 is formed on the inner peripheral surface of the peripheral wall portion 6 </ b> D of the cylindrical press contact body 6. The outer peripheral portion of the friction member 5 is prevented from coming into contact with the outer peripheral portion of the friction member 5, and the outer peripheral portion of the friction member 5 is prevented from bulging outward. Therefore, the friction shaft 5 is deformed so that the inner diameter of each friction member 5 is surely reduced, and the inner peripheral portion of each friction member 5 is pressed against the rotation shaft portion 4. The frictional resistance is increased.

また、この際、各摩擦体５の外周部が圧接体６の周壁部６Ｄの内周面に圧接することとなってこの各摩擦体５の外周部と圧接体６の周壁部６Ｄの内周面とにも摩擦抵抗が生じ、更に両側に位置する摩擦体５が、支承部12と圧接体６の底部に相当する部位の内面とに圧接して摩擦抵抗を生じ、これにより各摩擦体５が回動軸部４と共に簡単に回動してしまうことなく、回動軸部４に対して確実に摩擦回動抵抗を付与する構成としている。   At this time, the outer peripheral portion of each friction body 5 comes into pressure contact with the inner peripheral surface of the peripheral wall portion 6D of the press contact body 6 and the outer peripheral portion of each friction body 5 and the inner periphery of the peripheral wall portion 6D of the press contact body 6 Frictional resistance is also generated on the surface, and the friction bodies 5 located on both sides are pressed against the inner surface of the portion corresponding to the bottom portion of the support portion 12 and the press contact body 6 to generate friction resistance. Is configured to reliably apply frictional rotation resistance to the rotation shaft portion 4 without easily rotating together with the rotation shaft portion 4.

また、この圧接体６は、前記第一部材１に回り止め状態に取付する構成として、この圧接体６が前記ケース体14（カム係合部11）と共に回動軸部４に対し相対回動する構成としている。更に具体的には、圧接体６の周壁部６Ｄの外周面に係合凸部６Ｅを一体に突設する一方、この圧接体６が取付される第一部材の取付孔13に係合凸部６Ｅを係合する凹部13Ａを設けて、圧接体６を取付孔13に挿入取付した際に、係合凸部６Ｅを凹部13Ａに係合すると、圧接体６が第一部材に対して回り止め状態となる構成としている（図９参照。）。   Further, the pressure contact body 6 is configured to be attached to the first member 1 in a non-rotating state, and the pressure contact body 6 rotates relative to the rotation shaft portion 4 together with the case body 14 (cam engagement portion 11). It is configured to do. More specifically, the engaging convex portion 6E is integrally projected on the outer peripheral surface of the peripheral wall portion 6D of the press contact body 6, and the engaging convex portion is inserted into the mounting hole 13 of the first member to which the press contact body 6 is mounted. When the concave portion 13A for engaging 6E is provided and the press contact body 6 is inserted into and attached to the mounting hole 13, when the engagement convex portion 6E is engaged with the concave portion 13A, the press contact body 6 is prevented from rotating with respect to the first member. It is set as the structure which will be in a state (refer FIG. 9).

また、回動軸部４の延長部４Ａの先端部に押圧体９を一体に設けて、この押圧体９を圧接体６より延長部４Ａの先端側に配置し、第一部材１に対して第二部材２を回動させると、これに伴って押圧体９と圧接体６とが相対回動するように構成している。   In addition, a pressing body 9 is integrally provided at the distal end portion of the extension portion 4 </ b> A of the rotating shaft portion 4, and the pressing body 9 is disposed on the distal end side of the extension portion 4 </ b> A from the press contact body 6. When the second member 2 is rotated, the pressing body 9 and the press contact body 6 are configured to rotate relative to each other.

また、この押圧体９に、圧接体６を押圧する押圧突起部９Ａと圧接体６を押圧しない無押圧部９Ｂとを並設状態に設け、この押圧突起部９Ａと無押圧部９Ｂとに係合する係合部６Ａを圧接体６に設けて、第一部材１と第二部材２の所定の回動位置では係合部６Ａが無押圧部９Ｂに係合して圧接体６が押圧されず、この第一部材１と第二部材２の所定の回動位置から第一部材１に対し第二部材２を回動させた所定の回動範囲では係合部６Ａが前記押圧突起部９Ａに係合してこの押圧突起部９Ａに前記圧接体６が押圧されることになる前記押圧機構７を構成している。   Further, the pressing body 9 is provided with a pressing projection 9A that presses the pressing body 6 and a non-pressing section 9B that does not press the pressing body 6 in a juxtaposed state, and the pressing body 9 is related to the pressing projection 9A and the non-pressing section 9B. An engaging portion 6A to be joined is provided on the press contact body 6, and the engagement portion 6A is engaged with the non-pressing portion 9B at a predetermined rotation position of the first member 1 and the second member 2, and the press contact body 6 is pressed. First, in a predetermined rotation range in which the second member 2 is rotated relative to the first member 1 from a predetermined rotation position of the first member 1 and the second member 2, the engaging portion 6A is the pressing protrusion 9A. The pressing mechanism 7 is configured such that the press contact body 6 is pressed against the pressing protrusion 9A.

即ち、第一部材１と第二部材２の所定の回動位置から第一部材１に対し第二部材２を回動させた所定の回動範囲で、押圧機構７により圧接体６が摩擦体５に圧接して摩擦体５が押圧変形することによる摩擦回動抵抗（ブレーキ）が回動軸部４に生じ、これにより第一部材１に対する第二部材２の回動に抵抗が生じるようにしている。   That is, the pressure contact body 6 is a friction body by the pressing mechanism 7 in a predetermined rotation range in which the second member 2 is rotated with respect to the first member 1 from a predetermined rotation position of the first member 1 and the second member 2. Friction rotation resistance (brake) is generated in the rotation shaft portion 4 when the friction body 5 is pressed and deformed by being pressed against the rotation member 5, thereby generating resistance in rotation of the second member 2 relative to the first member 1. ing.

そして、本実施例では、第一部材１に対して第二部材２が９０度以上開放回動して開放回動する部材の自重が加わる回動範囲において、前記押圧機構７（押圧体９）が前記圧接体６を押圧し圧接体６が前記摩擦体５を押圧変形せしめて前記摩擦抵抗が生じ、開放回動位置へと到達する際の勢いを減速させるように、前記押圧突起部９Ａと無押圧部９Ｂとの並設位置関係並びに係合部６Ａの形成位置とを設定構成している。   In the present embodiment, the pressing mechanism 7 (the pressing body 9) is in a rotation range in which the second member 2 is opened and rotated 90 degrees or more with respect to the first member 1 and the weight of the member that opens and rotates is applied. Presses the pressure contact body 6 so that the pressure contact body 6 presses and deforms the friction body 5 so that the frictional resistance is generated and the moment when reaching the open rotation position is reduced. The side-by-side position relationship with the non-pressing portion 9B and the formation position of the engaging portion 6A are set and configured.

更に具体的には、押圧体９は、図８に示すように、やや厚みのある円盤状体に構成し、この押圧体９の圧接体６側に配する側面に、平坦面部を形成してこの平坦面部を前記無押圧部９Ｂとし、この無押圧部９Ｂと押圧体９の円周方向に並設状態にして、無押圧部９Ｂから徐々に上り傾斜する傾斜面を形成してこの傾斜面部を前記押圧突起部９Ａとしている。   More specifically, as shown in FIG. 8, the pressing body 9 is configured as a somewhat thick disc-shaped body, and a flat surface portion is formed on the side surface of the pressing body 9 that is disposed on the pressure contact body 6 side. The flat surface portion is defined as the non-pressing portion 9B, and the non-pressing portion 9B and the pressing body 9 are arranged in parallel in the circumferential direction to form an inclined surface that gradually rises from the non-pressing portion 9B. Is the pressing protrusion 9A.

また、この並設する無押圧部９Ｂと押圧突起部９Ａとの一組が押圧体９の中心を境にした対向位置に存するように構成すると共に、無押圧部９Ｂと押圧突起部９Ａとを押圧体９の中心を中心とする約９０度範囲に形成した構成としている。   In addition, a pair of the non-pressing portion 9B and the pressing projection portion 9A arranged side by side is configured to be located at an opposing position with the center of the pressing body 9 as a boundary, and the non-pressing portion 9B and the pressing projection portion 9A are provided. It is set as the structure formed in about 90 degree | times centering on the center of the press body 9. FIG.

一方、図９に示すように、前記圧接体６の押圧体９側の側面に、この対向側面の中心位置を境にした対向位置に突起部を形成してこの突起部を前記係合部６Ａとし、この対向位置に存する係合部６Ａ間の円周方向には、凹所６Ｂが形成される構成としている。   On the other hand, as shown in FIG. 9, a protrusion is formed on the side surface of the press contact body 6 on the side of the pressing body 9 at a position opposed to the center position of the opposite side surface, and the protrusion is formed as the engagement portion 6A. In addition, a recess 6B is formed in the circumferential direction between the engaging portions 6A existing at the facing position.

このように構成した押圧機構７の作動を説明すると、第一部材１に対して第二部材２を重合閉塞した状態（０度の状態）から第一部材１を９０度程起動するまでの回動範囲では、係合部６Ａが無押圧部９Ｂに係合すると共に、前記凹所６Ｂに押圧突起部６Ａが位置して圧接体６が押圧されない（回動抵抗は付与されない。）。   The operation of the pressing mechanism 7 configured as described above will be described. From the state in which the second member 2 is overlapped with respect to the first member 1 (the state of 0 degrees) until the first member 1 is started about 90 degrees. In the moving range, the engaging portion 6A engages with the non-pressing portion 9B, and the pressing protrusion 6A is positioned in the recess 6B so that the press contact body 6 is not pressed (no rotation resistance is given).

引き続いて、９０度起こされた第一部材１を９０度以上倒すように伏動回動させると、係合部６Ａが押圧突起部６Ａに乗り上げ係合してこの押圧突起部６Ａの傾斜面を上るように摺動し、これにより徐々に圧接部６がケース体14側へと押動されて前記摩擦体５が押圧変形していき、前記したように回動軸部４に摩擦回動抵抗が生じる。   Subsequently, when the first member 1 raised 90 degrees is tilted and rotated so as to be tilted 90 degrees or more, the engaging portion 6A rides on and engages with the pressing protrusion 6A, and the inclined surface of the pressing protrusion 6A is inclined. As a result, the pressure contact portion 6 is gradually pushed toward the case body 14 and the friction body 5 is pressed and deformed. Occurs.

この際、本実施例の押圧突起部９Ａは、押圧体９の円周方向に沿って徐々に突出度合いが大きくなる（高くなる）傾斜面形状に形成してあるため、第一部材１に対する第二部材２の開放回動角度を大きくさせるにしたがって次第にブレーキ作用（摩擦抵抗）が強くなる構成である。   At this time, the pressing protrusion 9A of the present embodiment is formed in an inclined surface shape in which the degree of protrusion gradually increases (becomes higher) along the circumferential direction of the pressing body 9, so The brake action (friction resistance) gradually increases as the opening rotation angle of the two members 2 is increased.

尚、本実施例の回動抵抗機構８は、摩擦体５の使用本数や材質の設定変更によりブレーキ効果（摩擦度合い）をコントロールすることが可能であり、また、同様に押圧体９の押圧突起部９Ａの高さ（突出度合い）や突出角度の設定変更によりブレーキ効果をコントロールすることが可能である。   In addition, the rotation resistance mechanism 8 of this embodiment can control the braking effect (friction degree) by changing the number of friction bodies 5 used and the setting of the material. It is possible to control the braking effect by changing the setting of the height (protrusion degree) and the protrusion angle of the portion 9A.

また、摩擦体５の周辺にグリスを塗布し、このグリスの硬さを変更することによってブレーキ効果をコントロールすることも可能である。   It is also possible to control the braking effect by applying grease around the friction body 5 and changing the hardness of the grease.

また、本実施例の回動抵抗機構８は、摩擦体５に側方から圧力を加え、この圧力方向と直交する方向に摩擦体５を圧延変形させて摩擦体５の内周部を回動軸部４に圧接させる構成のため、一般的なオイル式のダンパー装置のように各部品を非常に精度が高いものとせずとも、ダンパー（ブレーキ）効果のばらつきが部品精度の影響を受けにくいという利点もある。   Further, the rotation resistance mechanism 8 of the present embodiment applies pressure to the friction body 5 from the side, and rolls and deforms the friction body 5 in a direction orthogonal to the pressure direction to rotate the inner peripheral portion of the friction body 5. Due to the structure in which the shaft part 4 is pressed against each other, the variation in the damper (brake) effect is not easily affected by the component accuracy even if each component does not have a very high accuracy as in a general oil-type damper device. There are also advantages.

図中符号16は座金、17はカム部10を回動軸部４に回り止め状態に固定するための固定ピン、18は押圧体９を回動軸部４に回り止め状態に固定するための固定ピンである。   In the figure, reference numeral 16 is a washer, 17 is a fixing pin for fixing the cam portion 10 to the rotating shaft portion 4 in a non-rotating state, and 18 is a fixing pin for fixing the pressing body 9 to the rotating shaft portion 4. It is a fixed pin.

尚、本実施例では、第一部材１を第二部材２に対して９０度以上開放回動した時に回動軸部４に摩擦抵抗が生じる構成とした場合を示しているが、例えば、押圧機構７を構成する押圧体９の形状を設計変更することにより、第一部材１と第二部材２に対して閉塞する前の回動範囲で摩擦抵抗が生じるような構成とすることも容易にできるし、開放回動時と閉塞回動時の双方において摩擦抵抗が生じるように構成することも容易にできる。 In addition, although the present Example has shown the case where it was set as the structure which produces a frictional resistance in the rotating shaft part 4 when the 1st member 1 opens 90 degree | times or more with respect to the 2nd member 2, it shows the case where it presses, for example By changing the design of the shape of the pressing body 9 constituting the mechanism 7, it is easy to adopt a configuration in which frictional resistance is generated in the rotation range before the first member 1 and the second member 2 are closed. In addition, it is possible to easily configure such that frictional resistance is generated during both opening rotation and closing rotation .

尚、本発明は、本実施例に限られるものではなく、各構成要件の具体的構成は適宜設計し得るものである。 The present invention is not limited to this embodiment, and the specific configuration of each component can be designed as appropriate.

例えば、本実施例の摩擦体５は、ゴム製のＯリングを採用した場合を示したが、これに限定されるものではなく、弾性を有して変形する素材（例えばシリコンなど）製のものであれば何でも良い。 For example, although the friction body 5 of the present embodiment shows a case where a rubber O-ring is adopted, the friction body 5 is not limited to this, and is made of a material (for example, silicon) which has elasticity and is deformed. Anything is fine.
