Description

この発明は、筐体に扉を開閉回転可能に取り付けるためのヒンジ装置に関する。 The present invention relates to a hinge device for attaching a door to a housing so that the door can be opened and closed.

一般に、この種のヒンジ装置は、筐体に取り付けられる筐体側取付部材と、扉に取り付けられる扉側取付部材と、扉側取付部材を筐体側取付部材に回転可能に連結する第１及び第２リンクと、扉側取付部材を回転付勢する回転付勢手段とを有している。 In general, this type of hinge device includes a housing-side mounting member attached to the housing, a door-side mounting member attached to the door, and first and second connecting the door-side mounting member to the housing-side mounting member in a rotatable manner. It has a link and rotation biasing means for biasing the door side mounting member.

ヒンジ装置には、回転付勢手段が第１及び第２リンクの一方を介して扉側取付部材を回転付勢するタイプのものと、第１及び第２リンクの両者を介して扉側取付部材を回転付勢するタイプのものとがある。後者のタイプのヒンジ装置は、回転付勢手段が二つのリンクを同時に回転付勢するので、前者のタイプのヒンジ装置に比して扉側取付部材を大きな力で回転付勢することができるという利点がある。この発明は、後者のタイプの回転付勢手段が用いられたヒンジ装置に関する。 The hinge device includes a type in which the rotation urging means urges the door-side attachment member through one of the first and second links, and the door-side attachment member through both the first and second links. There is a type of rotating energizing. In the latter type of hinge device, the rotation urging means simultaneously urges the two links to rotate, so that the door-side mounting member can be urged to rotate with a larger force than the former type of hinge device. There are advantages. The present invention relates to a hinge device using the latter type of rotation urging means.

後者のタイプのヒンジ装置としては、例えば下記特許文献１に記載のものがある。このヒンジ装置においては、回転付勢手段として捩りコイルばねが用いられている。捩りコイルばねは、そのコイル部の長手方向の一端部及び他端部から突出する第１及び第２アームを有しており、第１及び第２アームが第１及び第２リンクにそれぞれ押し付けられ、それによって第１及び第２リンクを回転付勢している。 As the latter type of hinge device, for example, there is one described in Patent Document 1 below. In this hinge device, a torsion coil spring is used as the rotation urging means. The torsion coil spring has first and second arms protruding from one end and the other end in the longitudinal direction of the coil portion, and the first and second arms are pressed against the first and second links, respectively. Thereby, the first and second links are rotationally biased.

上記特許文献１に記載のヒンジ装置においては、筐体側取付部材に支持軸が設けられ、この支持軸に捩りコイルばねのコイル部が外挿されている。これにより、捩りコイルばねが支持軸を介して筐体側取付部材に位置固定状態で支持され、第１リンクと第２リンクとの間から外れることが防止されている。 In the hinge device described in Patent Document 1, a support shaft is provided on the housing-side mounting member, and a coil portion of a torsion coil spring is extrapolated to the support shaft. As a result, the torsion coil spring is supported by the housing-side mounting member via the support shaft in a fixed position, and is prevented from coming off between the first link and the second link.

ところが、コイル部に支持軸を挿通して捩りコイルばねを支持するという支持構造では、筐体側取付部材の内部に支持軸を設けるための空間が必要になる。ところが、最近のヒンジ装置では、筐体側取取付部材の内部に各種の部材あるいは各種の機構が設けられている。例えば、扉側取付部材の回転速度を低速に抑えるためのダンパ機構が設けられている。このため、筐体側取付部材の内部に支持軸を設けると、他の部材や機構の配置の邪魔になり、その分だけ設計の自由度が狭くなったり、あるいは筐体側取付部材が大型化したりするという問題があった。 However, in the support structure in which the support shaft is inserted into the coil portion to support the torsion coil spring, a space for providing the support shaft inside the housing side mounting member is required. However, in recent hinge devices, various members or various mechanisms are provided inside the housing side mounting member. For example, a damper mechanism is provided for suppressing the rotation speed of the door-side mounting member to a low speed. For this reason, if a support shaft is provided inside the housing-side mounting member, it interferes with the arrangement of other members and mechanisms, and the degree of freedom in design is reduced accordingly, or the housing-side mounting member is enlarged. There was a problem.

It is connected.

第１リンク３と第２リンク４との間には、回転付勢手段２０が設けられている。この回転付勢手段２０は、第１及び第２リンク３，４を回転付勢し、それによって扉側取付部材２及び扉Ｃを回転付勢するものであり、次のように構成されている。 A rotation biasing means 20 is provided between the first link 3 and the second link 4. The rotation urging means 20 urges the first and second links 3 and 4 to rotate and thereby urges the door-side mounting member 2 and the door C, and is configured as follows. .

図６に示すように、回転付勢手段２０は、複数の圧縮コイルばね２１と、圧縮コイルばね２１の一端部を保持する受け軸（第１ばね受け）２２と、圧縮コイルばね２１の他端部を保持するばね受け（第２ばね受け）２３とを有している。複数の圧縮コイルばね２１は、互いに平行に、しかも一直線上に並んで配置されている。圧縮コイルばね２１は、一つだけ用いてもよい。 As shown in FIG. 6, the rotation urging means 20 includes a plurality of compression coil springs 21, a receiving shaft (first spring receiver) 22 that holds one end of the compression coil spring 21, and the other end of the compression coil spring 21. And a spring receiver (second spring receiver) 23 for holding the portion. The plurality of compression coil springs 21 are arranged in parallel with each other and in a straight line. Only one compression coil spring 21 may be used.

受け軸２２は、回転付勢手段２０の一端部を構成するものであり、図２〜図５に示すように、その軸線を上下方向に向け、かつ第１枢軸１１からその径方向に離間して配置されている。つまり、受け軸２２は、第１枢軸１１と平行に配置されている。受け軸２２の両端部は、第１リンク３の一端部に設けられた支持孔３ａ，３ａに回転可能に挿入されている。これにより、受け軸２２が第１リンク３に離脱不能に設けられている。なお、受け軸２３は、扉Ｃが閉位置と開位置との間のいずれの位置に位置しているときにも、第１枢軸１１より後方に位置するように配置されているが、第１枢軸１１より前方に配置してもよい。 The receiving shaft 22 constitutes one end of the rotation urging means 20 and, as shown in FIGS. 2 to 5, its axis is directed in the vertical direction and is spaced from the first pivot 11 in the radial direction. Are arranged. That is, the receiving shaft 22 is disposed in parallel with the first pivot 11. Both end portions of the receiving shaft 22 are rotatably inserted into support holes 3 a and 3 a provided at one end portion of the first link 3. Thereby, the receiving shaft 22 is provided on the first link 3 so as not to be detached. The receiving shaft 23 is disposed so as to be located behind the first pivot 11 when the door C is located at any position between the closed position and the open position. You may arrange | position ahead of the pivot 11. FIG.

図６に示すように、受け軸２２の外周面には、圧縮コイルばね２１の一端部が圧縮コイルばね２１自体の付勢力によって押圧接触させられている。この結果、第１リンク３が第１枢軸１１を中心として回転するよう、圧縮コイルばね２１の付勢力により受け軸２２を介して回転付勢されている。 As shown in FIG. 6, one end of the compression coil spring 21 is pressed and brought into contact with the outer peripheral surface of the receiving shaft 22 by the urging force of the compression coil spring 21 itself. As a result, the first link 3 is rotationally biased via the receiving shaft 22 by the biasing force of the compression coil spring 21 so that the first link 3 rotates about the first pivot 11.

受け軸２２の外周面には、圧縮コイルばね２１と同数の係合軸部２２ａが設けられている。各係合軸部２２ａは、互いに平行に、しかも受け軸２２の長手方向に並んで設けられている。係合軸部２２ａは、受け軸２２から第２リンク４側へ向かって突出させられており、圧縮コイルばね２１の一端部に挿入されている。これにより、圧縮コイルばね２１の一端部が、受け軸２２にその径方向へ離脱不能に保持されている。 On the outer peripheral surface of the receiving shaft 22, the same number of engaging shaft portions 22 a as the compression coil springs 21 are provided. The engagement shaft portions 22 a are provided in parallel to each other and aligned in the longitudinal direction of the receiving shaft 22. The engagement shaft portion 22 a is projected from the receiving shaft 22 toward the second link 4 side, and is inserted into one end portion of the compression coil spring 21. Thereby, the one end part of the compression coil spring 21 is hold | maintained at the receiving shaft 22 so that it cannot detach | leave in the radial direction.

ばね受け２３は、回転付勢手段２０の他端部を構成するものであり、平板状に形成されている。ばね受け２３の第１リンク３側を向く一端面には、圧縮コイルばね２１と同数の受け孔２３ａが互いに平行に、かつ一列に並んで設けられている。各受け孔２３ａには、圧縮コイルばね２１の他端部がそれぞれ挿入されている。これにより、圧縮コイルばね２１の他端部がばね受け２３に離脱不能に保持されている。 The spring receiver 23 constitutes the other end of the rotation urging means 20 and is formed in a flat plate shape. On the one end face of the spring receiver 23 facing the first link 3 side, the same number of receiving holes 23a as the compression coil spring 21 are provided in parallel and in a line. The other end of the compression coil spring 21 is inserted into each receiving hole 23a. As a result, the other end of the compression coil spring 21 is held by the spring receiver 23 so as not to be detached.

第２リンク４の一端部には、略四角形状の凹部（第２凹部）２４が形成されている。この凹部２４は、第２枢軸１２からその径方向に離間して、より詳しくは第２枢軸から前方に離間して配置されている。しかも、凹部２４は、その開放部を第１リンク３側に向けて、より詳しくは係合軸部２２ａの長手方向に向けて形成されている。凹部２４には、ばね受け２３の他端部が挿入されている。ばね受け２３の他端部は、圧縮コイルばね２１の付勢力により凹部２４の底面に押し付けられている。この結果、第２リンク４が第２枢軸１２を中心として回転するよう、第２リンク４の一端部が圧縮コイルばね２１によりばね受け２３を介して回転付勢されている。しかも、凹部２４が四角形状をなしているので、凹部２４の底面に押し付けられたばね受け２２は、圧縮コイルばね２１の付勢力を越える力が作用しない限り凹部２４から脱出することがない。このようにして、回転付勢手段２０の他端部たるばね受け２２が、第２リンク４に離脱不能に係合されている。凹部２４は、第２枢軸１２より後方に配置してもよい。 A substantially quadrangular recess (second recess) 24 is formed at one end of the second link 4. The concave portion 24 is spaced apart from the second pivot 12 in the radial direction, and more specifically is spaced forward from the second pivot. Moreover, the recess 24 is formed with the opening portion directed toward the first link 3, more specifically in the longitudinal direction of the engagement shaft portion 22 a. The other end of the spring receiver 23 is inserted into the recess 24. The other end of the spring receiver 23 is pressed against the bottom surface of the recess 24 by the urging force of the compression coil spring 21. As a result, one end of the second link 4 is urged to rotate by the compression coil spring 21 via the spring receiver 23 so that the second link 4 rotates about the second pivot 12. Moreover, since the recess 24 has a quadrangular shape, the spring receiver 22 pressed against the bottom surface of the recess 24 does not escape from the recess 24 unless a force exceeding the urging force of the compression coil spring 21 is applied. In this way, the spring receiver 22 which is the other end of the rotation urging means 20 is engaged with the second link 4 so as not to be detached. The recess 24 may be disposed behind the second pivot 12.

なお、回転付勢手段２０は、第１及び第２リンク３，４を図１の反時計方向へ付勢し、それによって扉側取付部材２及び扉Ｃが回転付勢しているが、扉側取付部材２及び扉Ｃに対する回転付勢手段２０の回転付勢方向は、扉Ｃの回転位置に応じて変化する。すなわち、回転付勢手段２０は、扉Ｃが閉位置と所定の思案位置との間に位置しているときには、扉側取付部材２及び扉Ｃを開位置側から閉位置側へ付勢回転し、扉Ｃが思案位置と開位置との間に位置しているときには、扉側取付部材２及び扉Ｃを閉位置側から開位置側へ回転付勢する。これは、周知のヒンジ装置と同様であり、思案位置とは、第２枢軸１２、第１軸部１４及び第２軸部１５が一直線上に並んだときの扉側取付部材２の回転位置である。 The rotation urging means 20 urges the first and second links 3 and 4 in the counterclockwise direction of FIG. 1, and thereby the door side mounting member 2 and the door C are urged to rotate. The rotation urging direction of the rotation urging means 20 with respect to the side mounting member 2 and the door C changes according to the rotation position of the door C. That is, when the door C is located between the closed position and a predetermined thought position, the rotation urging means 20 urges and rotates the door side mounting member 2 and the door C from the open position side to the closed position side. When the door C is located between the thought position and the open position, the door side mounting member 2 and the door C are urged to rotate from the closed position side to the open position side. This is the same as the known hinge device, and the thought position is the rotational position of the door-side mounting member 2 when the second pivot shaft 12, the first shaft portion 14, and the second shaft portion 15 are aligned. is there.

上記構成のヒンジ装置においては、回転付勢手段２０の一端部たる受け軸２２が第１リンク３に離脱不能に係合されるとともに、回転付勢手段２０の他端部たるばね受け２３が第２リンク４に離脱不能に係合されて、その結果回転付勢手段２０が第１及び第２リンク３，４だけで保持されている。したがって、回転付勢手段２０を保持するための支持軸等の保持部材を筐体側取付部材１に設ける必要がなく、その分だけ筐体側取付部材１の有効利用可能な内部空間を広くすることができる。よって、筐体側取付部材１の内部に回転ダンパ等の各種の機構、部品、部材等を設ける場合には、その設置箇所の自由度、つまり設計の自由度を広げることができる。また、有効利用可能な内部空間を一定にするのであれば、筐体側取付部材１の小型化を図ることができる。 In the hinge device having the above-described configuration, the receiving shaft 22 as one end portion of the rotation urging means 20 is engaged with the first link 3 so as not to be detached, and the spring receiver 23 as the other end portion of the rotation urging means 20 is the first. The two links 4 are engaged with each other so as not to be detached, and as a result, the rotation urging means 20 is held only by the first and second links 3 and 4. Therefore, it is not necessary to provide the housing side mounting member 1 with a holding member such as a support shaft for holding the rotation urging means 20, and the internal space where the housing side mounting member 1 can be effectively used is widened accordingly. it can. Therefore, when various mechanisms, parts, members, etc., such as a rotary damper, are provided inside the housing-side mounting member 1, the degree of freedom of the installation location, that is, the degree of design freedom can be increased. Moreover, if the internal space which can be used effectively is made constant, the housing side mounting member 1 can be downsized.

なお、上記の第１実施の形態においては、受け軸２２に係合軸部２２ａを設け、ばね受け２３に受け孔２３ａを設けているが、受け軸（第１ばね受け）２２に受け孔を形成し、ばね受け（第２ばね受け）２３に係合軸部を形成してもよい。その場合には、受け軸２２の受け孔に圧縮コイルばね２１の一端部が挿入され、圧縮コイルばね２１の他端部にばね受け２３の係合軸部が挿入される。 In the first embodiment, the receiving shaft 22 is provided with the engaging shaft portion 22a and the spring receiver 23 is provided with the receiving hole 23a. However, the receiving shaft (first spring receiver) 22 has a receiving hole. The engagement shaft portion may be formed on the spring receiver (second spring receiver) 23. In that case, one end of the compression coil spring 21 is inserted into the receiving hole of the receiving shaft 22, and the engaging shaft portion of the spring receiver 23 is inserted into the other end of the compression coil spring 21.

また、受け軸２２を第１リンク３の支持孔３ａに回転可能に嵌合し、受け部材２２を凹部２４に係合させているが、これとは逆に第１リンク３に凹部を形成して、この凹部に受け軸２２を係合させ、第２リンク４に支持孔を形成して、この支持孔に受け部材２２を回転可能に嵌合させてもよい。 In addition, the receiving shaft 22 is rotatably fitted in the support hole 3a of the first link 3 and the receiving member 22 is engaged with the recess 24. On the contrary, a recess is formed in the first link 3. Then, the receiving shaft 22 may be engaged with the recess, a support hole may be formed in the second link 4, and the receiving member 22 may be rotatably fitted in the support hole.

次に、この発明の他の実施の形態について説明する。なお、以下の実施の形態については、上記実施の形態と異なる構成だけを説明することとし、上記実施の形態と同様な部分には同一符号を付してその説明を省略する。 Next, another embodiment of the present invention will be described. In the following embodiment, only the configuration different from the above embodiment will be described, and the same parts as those in the above embodiment are denoted by the same reference numerals and the description thereof will be omitted.

図７〜図１０は、この発明の第２実施の形態を示す。この実施の形態のヒンジ装置Ａ２においては、上記実施の形態の回転付勢手段２０に代えて回転付勢手段２０Ａが用いられている。回転付勢手段２０Ａのばね受け２３の上下方向の両端面には、軸部２３ｂ，２３ｂがそれぞれ一体に設けられている（図９に下側の軸部２２ｂのみ図示）。軸部２３ｂは、第２枢軸１２と平行に配置されている。一方、第２リンク４の一端部には、支持孔４ａ，４ａが設けられている。支持孔４ａは、第２枢軸１２からその径方向に離間して配置されており、第２枢軸１２と平行に形成されている。各支持孔４ａ，４ａには、ばね受け２３の軸部２３ｂ，２３ｂがそれぞれ回転可能に嵌合されている。これにより、圧縮コイルばね２１の付勢力が第２リンク４にばね受け２３を介して伝達されるとともに、ばね受け２３が第２リンク４に離脱不能に係合されている。 7 to 10 show a second embodiment of the present invention. In the hinge device A2 of this embodiment, a rotation biasing means 20A is used instead of the rotation biasing means 20 of the above embodiment. Shaft portions 23b, 23b are integrally provided on both end surfaces in the vertical direction of the spring receiver 23 of the rotation urging means 20A (only the lower shaft portion 22b is shown in FIG. 9). The shaft portion 23 b is disposed in parallel with the second pivot shaft 12. On the other hand, support holes 4 a and 4 a are provided at one end of the second link 4. The support hole 4 a is disposed away from the second pivot 12 in the radial direction, and is formed in parallel with the second pivot 12. The shaft portions 23b and 23b of the spring receiver 23 are fitted in the support holes 4a and 4a, respectively, so as to be rotatable. Thereby, the urging force of the compression coil spring 21 is transmitted to the second link 4 via the spring receiver 23, and the spring receiver 23 is engaged with the second link 4 so as not to be detached.

なお、軸部２３ｂは、扉Ｃが閉位置と開位置とのいずれの位置に位置しているときにも第２枢軸１２より前方に位置するように配置されているが、第２枢軸１２より後方に位置するように配置してもよい。また、軸部２３ｂは、ばね受け２２に一体に形成することなく、独立した支持軸としてばね受け２２とは別体に形成してもよい。 The shaft portion 23b is disposed so as to be positioned in front of the second pivot 12 when the door C is located at either the closed position or the open position. You may arrange | position so that it may be located back. Further, the shaft portion 23 b may be formed separately from the spring receiver 22 as an independent support shaft without being formed integrally with the spring receiver 22.

図１１〜図１４は、この発明の第３実施の形態を示す。この実施の形態のヒンジ装置Ａ３においては、回転付勢手段２０に代えて回転付勢手段２０Ｂが用いられている。この回転付勢手段２０Ｂにおいては、第１リンク３の一端部にカム凹部（第１凹部）２６が形成されている。このカム凹部２６は、第１枢軸１１からその径方向に離間して配置されている。しかも、カム凹部２６は、その開放部が圧縮コイルばね２１の軸線方向を向き、かつ受け軸２２と対向するように配置されている。カム凹部２６には、受け軸２２が挿入されている。受け軸２２は、圧縮コイルばね２１の付勢力によってカム凹部２６の底面に押し付けられている。これにより、第１リンク３が第１枢軸１１を中心として回転付勢されるとともに、受け軸２２が第１リンク３に離脱不能に係合されている。 11 to 14 show a third embodiment of the present invention. In the hinge device A3 of this embodiment, a rotation biasing means 20B is used instead of the rotation biasing means 20. In the rotation urging means 20B, a cam recess (first recess) 26 is formed at one end of the first link 3. The cam recess 26 is disposed away from the first pivot 11 in the radial direction. In addition, the cam recess 26 is disposed so that the open portion faces the axial direction of the compression coil spring 21 and faces the receiving shaft 22. A receiving shaft 22 is inserted into the cam recess 26. The receiving shaft 22 is pressed against the bottom surface of the cam recess 26 by the urging force of the compression coil spring 21. As a result, the first link 3 is urged to rotate about the first pivot 11, and the receiving shaft 22 is engaged with the first link 3 so as not to be detached.

この実施の形態のヒンジ装置Ａ３においては、扉側取付部材２（扉Ｃ）が回転すると、それに伴って受け軸２２がカム凹部２６内を前後方向へ移動し、受け軸２２の第１リンク３に対する接触箇所が前後方向へ変化する。この結果、図１１及び図１２と図１３との比較から明らかなように、扉側取付部材２が閉位置と思案位置との間に位置しているときには、回転付勢手段２０Ｂが第１リンク３を反時計方向へ回転付勢し、扉側取付部材２が思案位置と開位置との間に位置しているときには、回転付勢手段２０Ｂが第１リンク３を時計方向へ回転付勢する。 In the hinge device A3 of this embodiment, when the door-side mounting member 2 (door C) rotates, the receiving shaft 22 moves in the front-rear direction in the cam recess 26 along with this, and the first link 3 of the receiving shaft 22 The contact location with respect to changes in the front-back direction. As a result, as is clear from comparison between FIG. 11 and FIG. 12 and FIG. 13, when the door-side mounting member 2 is located between the closed position and the considered position, the rotation urging means 20B is connected to the first link. When the door side mounting member 2 is positioned between the imaginary position and the open position, the rotation urging means 20B urges the first link 3 to rotate clockwise. .

図１５〜図１８は、この発明の第４実施の形態を示す。この実施の形態のヒンジ装置Ａ４においては、回転付勢手段として板ばね３１が用いられている。板ばね３１は、略「Ｕ」字状をなしており、その一端部には、筒部３１ａが形成されている。板ばね３１の他端部には、外側に向かって凸曲面状をなす当接部３１ｂが形成されている。 15 to 18 show a fourth embodiment of the present invention. In the hinge device A4 of this embodiment, the leaf spring 31 is used as the rotation biasing means. The leaf spring 31 has a substantially “U” shape, and a cylindrical portion 31 a is formed at one end thereof. At the other end of the leaf spring 31, a contact portion 31b having a convex curved surface shape is formed outward.

第１リンク３の一端部には、連結軸３２が第１枢軸１１と平行に、かつ位置固定して設けられている。連結軸３２は、第１枢軸１１より後方に配置されている。連結軸３２は、板ばね３１の筒部３１ａに挿入されている。この結果、板ばね３１の一端部が第１リンク３に連結軸３２を介して回転可能に、かつ離脱不能に係合されている。しかも、第１リンク３の第１枢軸１１から離間した一端部が板ばね３１によって回転付勢されている。 A connecting shaft 32 is provided at one end of the first link 3 in parallel with the first pivot 11 and at a fixed position. The connecting shaft 32 is disposed behind the first pivot shaft 11. The connecting shaft 32 is inserted into the cylindrical portion 31 a of the leaf spring 31. As a result, one end of the leaf spring 31 is engaged with the first link 3 via the connecting shaft 32 so as to be rotatable and not removable. In addition, one end portion of the first link 3 that is separated from the first pivot 11 is rotationally biased by the leaf spring 31.

第２リンク４の一端部には、カム面３３が形成されている。このカム面３３は、第２枢軸１２からその径方向へ離間して箇所に形成されており、第１リンク３側を向くように配置されている。カム面３３には、板ばね３１の当接部３１ｂが板ばね３１自体の付勢力によって押し付けられている。この結果、第２リンク４が第２枢軸１２を中心として反時計方向へ回転付勢されるとともに、第１リンク３が第１枢軸１１を中心として反時計方向へ回転付勢されている。 A cam surface 33 is formed at one end of the second link 4. The cam surface 33 is formed at a location away from the second pivot 12 in the radial direction, and is arranged to face the first link 3 side. The contact surface 31b of the leaf spring 31 is pressed against the cam surface 33 by the urging force of the leaf spring 31 itself. As a result, the second link 4 is urged to rotate counterclockwise about the second pivot 12, and the first link 3 is urged to rotate counterclockwise about the first pivot 11.

ここで、板ばね３１の他端部は、板ばね３１自体の付勢力によって当接部３１ｂがカム面３３に押し付けられているだけである。しかし、筒部３１ａに連結軸３２が挿入されることにより、板ばね３１の一端部が第１リンク３に位置固定されているので、板ばね３１の付勢力によってカム面３３に押し付けられた当接部３１ｂは、当接部３１ｂに板ばね３１の付勢力を越える力が作用しない限りカム面３３から離脱することがない。したがって、板ばね３１の他端部は、第２リンク４の一端部に離脱不能に係合されている。その結果、板ばね３１が第１及び第２リンク３，４によって保持されている。 Here, the other end portion of the leaf spring 31 is merely pressed against the cam surface 33 by the urging force of the leaf spring 31 itself. However, since the end of the leaf spring 31 is fixed to the first link 3 by inserting the connecting shaft 32 into the cylinder portion 31a, the contact force pressed against the cam surface 33 by the urging force of the leaf spring 31 is fixed. The contact portion 31b is not detached from the cam surface 33 unless a force exceeding the urging force of the leaf spring 31 is applied to the contact portion 31b. Therefore, the other end of the leaf spring 31 is engaged with one end of the second link 4 so as not to be detached. As a result, the leaf spring 31 is held by the first and second links 3 and 4.

図１９〜図２２は、この発明の第５実施の形態を示す。この実施の形態のヒンジ装置Ａ５は、上記第４実施の形態のヒンジ装置Ａ４を変形したものであり、板ばね３１の他端部と第２リンク４の一端部との係合状態がヒンジ装置Ａ４と異なっている。 19 to 22 show a fifth embodiment of the present invention.
