Description

本発明は、ベース部材と、ベース部材に枢支されて回動する回動部材と、回動部材を付勢する付勢部材と、を有する回動構造体に関する。 The present invention relates to a rotating structure including a base member, a rotating member that is pivotally supported by the base member, and an urging member that urges the rotating member.

回動軸を有する回動部材がベース部材に対して回動する回動構造体として、従来から種々のものが知られている。その一例として、回動軸を有するリッドと当該リッドの回動軸を枢支するケースとを有する蓋付収容装置を挙げることができる。この種の回動構造体においては、リッドすなわち回動部材が回動して、ケースすなわちベース部材の開口を開閉する。この種の蓋付収容装置の具体例として、車載用のドリンクホルダやコンソールボックス等を挙げることができる。 Conventionally, various rotating structures in which a rotating member having a rotating shaft rotates with respect to a base member are known. As an example thereof, a lidded storage device having a lid having a rotating shaft and a case that pivotally supports the rotating shaft of the lid can be mentioned. In this type of rotating structure, the lid, that is, the rotating member, rotates to open and close the opening of the case, that is, the base member. Specific examples of this type of lidded storage device include an in-vehicle drink holder and a console box.

ところで、この種の回動構造体において、バネ等の付勢部材によって回動部材を付勢する技術がある（例えば、特許文献１〜３参照）。付勢部材を備える回動構造体においては、回動部材が少なくとも一部の回動区間において自動的に回動するため、回動構造体の使い勝手が向上する。 By the way, in this kind of rotation structure, there exists a technique which urges | biases a rotation member by urging members, such as a spring (for example, refer patent documents 1-3). In the rotating structure including the urging member, the rotating member automatically rotates in at least a part of the rotation section, so that the usability of the rotating structure is improved.

特許文献１〜３に開示されているように、この種の回動構造体では、付勢部材としてねじりコイルバネ（所謂トーションバネ）を用いるのが一般的である。ねじりコイルバネの一端部はベース部材に取り付けられ、ねじりコイルバネの他端部は回動部材に取り付けられ、ねじりコイルバネのコイル部は回動軸に装着される。そして、当該コイル部を中心とするモーメントによってねじりコイルバネの付勢力は発揮される。このためねじりコイルバネは比較的大型であり、例えば回動部材が小型であったり軽量であったりする場合には、ねじりコイルバネからなる付勢部材を適用し難い場合があった。さらにねじりコイルバネは、付勢力を蓄積した状態で回動部材およびベース部材に取り付ける必要があるが、ねじりコイルバネに付勢力を蓄積するためにはねじりコイルバネの二端部を押さえ込み弾性変形させる必要がある。このような状態のねじりコイルバネを回動部材およびベース部材に取り付ける作業は非常に煩雑であり、組立作業者に負担を与える可能性もある。 As disclosed in Patent Documents 1 to 3, in this type of rotating structure, a torsion coil spring (so-called torsion spring) is generally used as a biasing member. One end of the torsion coil spring is attached to the base member, the other end of the torsion coil spring is attached to the rotating member, and the coil portion of the torsion coil spring is attached to the rotating shaft. And the urging | biasing force of a torsion coil spring is exhibited by the moment centering on the said coil part. For this reason, the torsion coil spring is relatively large. For example, when the rotating member is small or light, it may be difficult to apply the biasing member made of the torsion coil spring. Further, the torsion coil spring needs to be attached to the rotating member and the base member in a state where the urging force is accumulated, but in order to accumulate the urging force in the torsion coil spring, it is necessary to press and elastically deform the two ends of the torsion coil spring. . The operation of attaching the torsion coil spring in such a state to the rotating member and the base member is very complicated and may give a burden to the assembling worker.

付勢部材として、ねじりコイルバネに代えて板バネを用い、当該板バネをベース部材に組み付けるとともに当該板バネの付勢力を回動部材に作用させることで回動部材を付勢する方法も考えられる。この場合には、上記したねじりコイルバネを付勢部材として用いる場合に比べて、付勢部材を小型化でき、また、付勢部材をベース部材および回動部材に取り付ける作業も比較的容易になる。 As a biasing member, a method of using a plate spring instead of the torsion coil spring, assembling the plate spring to the base member, and biasing the rotating member by applying a biasing force of the plate spring to the rotating member is also conceivable. . In this case, as compared with the case where the torsion coil spring is used as the urging member, the urging member can be reduced in size, and the operation of attaching the urging member to the base member and the rotating member becomes relatively easy.

しかしこの場合には、回動部材が回動する際に、板バネが回動部材に対して摺接する。このため、回動部材の硬度や、板バネの付勢力や形状等によっては、回動部材が回動する際に付勢部材が回動部材を削り、回動部材の削り屑が生じる場合がある。そして当該削り屑が付勢部材と回動部材との間に挟まると、回動部材が回動する際に異音が生じる可能性があった。 However, in this case, when the rotating member rotates, the leaf spring comes into sliding contact with the rotating member. For this reason, depending on the hardness of the rotating member and the urging force and shape of the leaf spring, the urging member may scrape the rotating member when the rotating member rotates, and shavings of the rotating member may be generated. is there. When the shavings are sandwiched between the biasing member and the rotating member, there is a possibility that abnormal noise may be generated when the rotating member rotates.

図１に示すように、実施例の回動構造体は、ケース１と、リッド３と、付勢部材５とを有する。 As shown in FIG. 1, the rotating structure according to the embodiment includes a case 1, a lid 3, and an urging member 5.

ケース１には一対の枢支部１０が設けられている。ケース１は上方に開口する箱状をなす。このケース１の開口を収容開口２０と呼ぶ。一方の枢支部１０である第１枢支部１１はケース１の前側壁に設けられ、他方の枢支部１０である第２枢支部１２はケース１の後側壁に設けられている。第１枢支部１１および第２枢支部１２は、各々前後に延びる貫通孔を有し、ケース１に対して前後対称な位置に配置されている。 The case 1 is provided with a pair of pivot portions 10. The case 1 has a box shape that opens upward. The opening of the case 1 is referred to as an accommodation opening 20. The first pivot part 11 that is one pivot part 10 is provided on the front side wall of the case 1, and the second pivot part 12 that is the other pivot part 10 is provided on the rear side wall of the case 1. The first pivot part 11 and the second pivot part 12 each have a through hole extending in the front-rear direction, and are disposed at positions symmetrical with respect to the case 1.

図１に示すように、リッド３は、略板状をなす本体部３０と、筒状をなし本体部３０に一体に形成されている外軸部３１と、棒状をなし本体部３０および外軸部３１とは別体の内軸部３２と、外軸部３１に一体に形成されている摺接部４と、を有する。
外軸部３１の一端３１ａは本体部３０の前端部からさらに前方に延出している。外軸部３１の他端３１ｂは本体部３０の後端部からさらに後方に延出している。外軸部３１は、第１枢支部１１と第２枢支部１２との間（図１に示す前後方向における間の位置）において、第１枢支部１１および第２枢支部１２と同軸的に配置されている。
内軸部３２は、第１枢支部１１、外軸部３１および第２枢支部１２の内部に挿通されている。したがって、実施例１の回動構造体における回動軸３５は、外軸部３１と内軸部３２とで構成され、当該外軸部３１および内軸部３２で構成される回動軸３５は第１枢支部１１および第２枢支部１２で構成される枢支部１０に枢支される。そして、当該回動軸３５を中心としてリッド３が回動する。リッド３は、図２中実線で表される閉位置と、図２中２点鎖線で表される開位置と、の間を回動する。リッド３は、閉位置においてケース１の収容開口２０を閉じ、開位置において収容開口２０を開く。 As shown in FIG. 1, the lid 3 includes a substantially plate-shaped main body portion 30, a cylindrical outer shaft portion 31 formed integrally with the main body portion 30, a rod-shaped main body portion 30 and an outer shaft. The portion 31 includes an inner shaft portion 32 that is a separate body, and a sliding contact portion 4 that is formed integrally with the outer shaft portion 31.
One end 31 a of the outer shaft portion 31 extends further forward from the front end portion of the main body portion 30. The other end 31 b of the outer shaft portion 31 extends further rearward from the rear end portion of the main body portion 30. The outer shaft portion 31 is disposed coaxially with the first pivot portion 11 and the second pivot portion 12 between the first pivot portion 11 and the second pivot portion 12 (position in the front-rear direction shown in FIG. 1). Has been.
The inner shaft portion 32 is inserted into the first pivot portion 11, the outer shaft portion 31 and the second pivot portion 12. Therefore, the rotation shaft 35 in the rotation structure of the first embodiment is configured by the outer shaft portion 31 and the inner shaft portion 32, and the rotation shaft 35 configured by the outer shaft portion 31 and the inner shaft portion 32 is The first pivot part 11 and the second pivot part 12 are pivotally supported by the pivot part 10. Then, the lid 3 rotates about the rotation shaft 35. The lid 3 rotates between a closed position represented by a solid line in FIG. 2 and an open position represented by a two-dot chain line in FIG. The lid 3 closes the accommodation opening 20 of the case 1 in the closed position and opens the accommodation opening 20 in the open position.

図１に示すように、外軸部３１の後端部には、摺接部４が一体化されている。摺接部４は外軸部３１よりもやや大径の円筒状をなし、外軸部３１と同軸的に配置されている。内軸部３２は摺接部４の内部にも挿通されている。摺接部４の外周面４０には、後述する付勢部材５が摺接する摺接領域４０ａが設けられている。摺接領域４０ａは、摺接部４の外周面４０における周方向の一部の領域を構成する。したがって、摺接領域４０ａは摺接部の周方向に湾曲する湾曲面といえる。より具体的には、図３および図５〜図９に示すように、摺接領域４０ａは、中心角約４５°となるように摺接部４の周方向に沿って延びる。また、図３および図５〜図９に示すように、摺接領域４０ａのなかで当該周方向の略中央に位置する変曲部４０ｉは、回動軸３５の径方向に向けて隆起している。 As shown in FIG. 1, the sliding contact portion 4 is integrated with the rear end portion of the outer shaft portion 31. The sliding contact portion 4 has a cylindrical shape slightly larger in diameter than the outer shaft portion 31 and is disposed coaxially with the outer shaft portion 31. The inner shaft portion 32 is also inserted into the sliding contact portion 4. The outer peripheral surface 40 of the slidable contact portion 4 is provided with a slidable contact region 40a in which an urging member 5 described later slidably contacts. The sliding contact area 40 a constitutes a partial area in the circumferential direction on the outer peripheral surface 40 of the sliding contact portion 4. Therefore, it can be said that the sliding contact area 40a is a curved surface that curves in the circumferential direction of the sliding contact portion. More specifically, as shown in FIGS. 3 and 5 to 9, the sliding contact region 40 a extends along the circumferential direction of the sliding contact portion 4 so as to have a central angle of about 45 °. Further, as shown in FIGS. 3 and 5 to 9, the inflection portion 40 i located substantially in the center in the circumferential direction in the sliding contact region 40 a is raised toward the radial direction of the rotation shaft 35. Yes.

図５に示すように、回動軸３５から摺接領域４０ａまでの距離は、摺接領域４０ａの周方向の二端部（第１端部４０ｘ、第２端部４０ｙ）においてほぼ等しい。そして、回動軸３５から摺接領域４０ａまでの距離は、当該第１端部４０ｘおよび第２端部４０ｙから変曲部４０ｉに向けて徐々に大きくなっている。さらに換言すると、変曲部４０ｉにおいて摺接部４の隆起高さは最大となり、変曲部４０ｉから第１端部４０ｘおよび第２端部４０ｙに向けて摺接部４の隆起高さは徐々に低くなっている。 As shown in FIG. 5, the distance from the rotation shaft 35 to the sliding contact area 40a is substantially equal at the two ends (first end 40x, second end 40y) in the circumferential direction of the sliding contact area 40a. The distance from the rotation shaft 35 to the sliding contact region 40a gradually increases from the first end 40x and the second end 40y toward the inflection 40i. In other words, the raised height of the sliding contact portion 4 is maximized at the inflection portion 40i, and the rising height of the sliding contact portion 4 gradually increases from the inflection portion 40i toward the first end portion 40x and the second end portion 40y. It is low.

図３および図４に示すように、摺接部４には溝状の回収部４１が設けられている。回収部４１は、摺接領域４０ａの第１端部４０ｘと第２端部４０ｙとの間に延在し、摺接領域４０ａ、つまり、摺接部４の外周面４０に開口している。換言すると、回収部４１は、摺接領域４０ａ、つまり、摺接部４の外周面４０から、摺接部４の径方向内方に向けて陥没形成されている。さらに回収部４１は、第１端部４０ｘから第２端部４０ｙまでの間に形成されている。回収部４１の開口４１ｏは、第１端部４０ｘから第２端部４０ｙまでの間においてＳ字状に湾曲している。 As shown in FIGS. 3 and 4, the sliding contact portion 4 is provided with a groove-like recovery portion 41. The collection unit 41 extends between the first end 40x and the second end 40y of the sliding contact area 40a and opens to the sliding contact area 40a, that is, the outer peripheral surface 40 of the sliding contact section 4. In other words, the recovery part 41 is formed to be recessed from the sliding contact area 40 a, that is, from the outer peripheral surface 40 of the sliding contact part 4 toward the radially inner side of the sliding contact part 4. Furthermore, the collection unit 41 is formed between the first end 40x and the second end 40y. The opening 41o of the collection unit 41 is curved in an S shape between the first end 40x and the second end 40y.

更に換言すると、図４に示す摺接部４の展開図において、摺接領域４０ａは平面で表され、回収部４１の開口４１ｏは、当該摺接領域４０ａの外周を表す直線Ｌ０に対して交差するように延設されている。直線Ｌ０の延びる方向は、回動軸３５を中心とする円の周方向に一致するため、開口４１ｏは、回動軸３５を中心とする円の周方向に対して交差する方向に延びているとも言える。同様に、開口４１ｏの縁部４１ｅもまた、回動軸３５を中心とする円の周方向に対して交差する方向に延びているとも言える。実施例１の回動構造体においては、開口４１ｏの縁部４１ｅの全体が、回動軸３５を中心とする円の周方向に対して交差する方向に延びている。
なお、実施例１の回動構造体において、回収部４１の開口４１ｏ深さおよび開口４１ｏ幅は一定である。
以下、必要に応じて、「回動軸３５を中心とする円の周方向」を単に「回動軸３５の周方向」と呼ぶ場合がある。 In other words, in the developed view of the sliding contact portion 4 shown in FIG. 4, the sliding contact region 40a is represented by a plane, and the opening 41o of the collecting portion 41 intersects the straight line L0 representing the outer periphery of the sliding contact region 40a. It is so extended. Since the direction in which the straight line L0 extends coincides with the circumferential direction of the circle having the rotation axis 35 as the center, the opening 41o extends in a direction intersecting the circumferential direction of the circle having the rotation axis 35 as the center. It can also be said. Similarly, it can be said that the edge 41e of the opening 41o also extends in a direction intersecting the circumferential direction of the circle having the rotation shaft 35 as the center. In the rotating structure of the first embodiment, the entire edge 41e of the opening 41o extends in a direction intersecting the circumferential direction of the circle having the rotating shaft 35 as the center.
In the rotating structure according to the first embodiment, the depth of the opening 41o and the width of the opening 41o of the collection unit 41 are constant.
Hereinafter, the “circumferential direction of the circle around the rotation shaft 35” may be simply referred to as “the circumferential direction of the rotation shaft 35” as necessary.

付勢部材５は、弾性変形可能でありケース１に取り付けられている。実施例１の回動構造体における付勢部材５は、板バネであり、図５〜図９に示すようにＳ字状をなす。より具体的には、付勢部材５は、互いに逆方向に湾曲する二つの湾曲部（第１湾曲部５１、第２湾曲部５２）と、第１湾曲部５１に連続する入力部５３と、第２湾曲部５２に連続する固定部５４と、第１湾曲部５１と第２湾曲部５２とを接続する直状の連結部５５と、を有するＳ字状をなす。付勢部材５は、図３中破線で示すように入力部５３を摺接領域４０ａに対面させつつ、ケース１に取り付けられている。 The urging member 5 is elastically deformable and is attached to the case 1. The urging member 5 in the rotating structure of the first embodiment is a leaf spring and has an S shape as shown in FIGS. More specifically, the urging member 5 includes two bending portions (a first bending portion 51 and a second bending portion 52) that are bent in opposite directions, an input portion 53 that is continuous with the first bending portion 51, and It has an S-shape having a fixing portion 54 that is continuous with the second bending portion 52 and a straight connecting portion 55 that connects the first bending portion 51 and the second bending portion 52. The urging member 5 is attached to the case 1 with the input portion 53 facing the sliding contact area 40a as indicated by a broken line in FIG.

リッド３が閉位置と開位置との間の中立位置にある時には、図６および図８に示すように、摺接部４は変曲部４０ｉつまり隆起高さの最大となる部分を付勢部材５の入力部５３に向ける。つまり、図６および図８に示すようにリッド３が中立位置にある時には、摺接部４の摺接領域４０ａが入力部５３に圧接して、付勢部材５には付勢力が蓄積される。図６および図８に示す摺接部４の位置を、摺接部４の押圧位置と呼ぶ。リッド３が中立位置にある時に摺接部４は押圧位置にある。 When the lid 3 is in a neutral position between the closed position and the open position, as shown in FIGS. 6 and 8, the sliding contact portion 4 has the inflection portion 40 i, that is, the portion having the maximum raised height as a biasing member. 5 to the input unit 53. That is, as shown in FIGS. 6 and 8, when the lid 3 is in the neutral position, the slidable contact region 40 a of the slidable contact portion 4 is pressed against the input portion 53 and the urging force is accumulated in the urging member 5. . The position of the sliding contact portion 4 shown in FIGS. 6 and 8 is referred to as a pressing position of the sliding contact portion 4. When the lid 3 is in the neutral position, the sliding contact portion 4 is in the pressing position.

一方、リッド３が閉位置にある時、および、リッド３が開位置にある時には、図５、図９および図７に示すように摺接部４は変曲部４０ｉを入力部５３から逸らす。したがって、このとき摺接部４は隆起高さの小さい部分を入力部５３に向けるため、摺接部４の摺接領域４０ａと入力部５３とは互いに当接するだけで圧接しないか、或いは、僅かに圧接するのみである。つまり、リッド３が閉位置にある時（図５および図９）、および、リッド３が開位置にある時（図７）には、付勢部材５には付勢力が蓄積されないか、または付勢部材５に蓄積される付勢力は小さい。図５および図９に示す摺接部４の位置を、摺接部４の閉解除位置と呼ぶ。リッド３が閉位置にある時に摺接部４は閉解除位置にある。図７に示す摺接部４の位置を、摺接部４の開解除位置と呼ぶ。リッド３が開位置にある時に摺接部４は開解除位置にある。 On the other hand, when the lid 3 is in the closed position and when the lid 3 is in the open position, the sliding contact portion 4 deflects the inflection portion 40 i from the input portion 53 as shown in FIGS. 5, 9, and 7. Accordingly, at this time, since the sliding contact portion 4 has a portion with a small raised height directed to the input portion 53, the sliding contact area 40a of the sliding contact portion 4 and the input portion 53 are merely in contact with each other and are not in pressure contact with each other. It is only pressed against. That is, when the lid 3 is in the closed position (FIGS. 5 and 9) and when the lid 3 is in the open position (FIG. 7), the urging force is not accumulated or applied to the urging member 5. The urging force accumulated in the urging member 5 is small. The position of the sliding contact portion 4 shown in FIGS. 5 and 9 is referred to as a closing release position of the sliding contact portion 4. When the lid 3 is in the closed position, the sliding contact portion 4 is in the closed release position. The position of the sliding contact portion 4 shown in FIG. 7 is referred to as the opening release position of the sliding contact portion 4. When the lid 3 is in the open position, the sliding contact portion 4 is in the open release position.

リッド３が閉位置から中立位置に向けて回動すると、リッド３の一部を構成する摺接部４もまた、図５に示す閉解除位置から図６に示す押圧位置に向けて回動する。このとき、入力部５３に対する摺接部４の押圧力は徐々に大きくなる。このため、付勢部材５には付勢力が蓄積される。特に、このとき主として第１湾曲部５１が閉じる方向に変形し、付勢部材５には付勢力が蓄積される。そしてこのとき付勢部材５の付勢力により、リッド３は閉位置に向けて付勢される。 When the lid 3 is rotated from the closed position toward the neutral position, the sliding contact portion 4 constituting a part of the lid 3 is also rotated from the closed release position shown in FIG. 5 toward the pressing position shown in FIG. . At this time, the pressing force of the sliding contact portion 4 against the input portion 53 gradually increases. For this reason, the urging force is accumulated in the urging member 5. In particular, at this time, the first bending portion 51 is mainly deformed in the closing direction, and the urging force is accumulated in the urging member 5. At this time, the lid 3 is urged toward the closed position by the urging force of the urging member 5.

付勢部材５の付勢力に抗してリッド３を中立位置からさらに開位置に向けて回動させると、入力部５３は変曲部４０ｉを乗り越える。すると入力部５３に対する摺接部４の押圧力は減少する。すると付勢部材５は、付勢力を放出し、摺接部４の押圧力がより小さくなる方向、つまり、図６に示す押圧位置から図７に示す開解除位置に向けて摺接部４を押圧する。換言すると、このとき付勢部材５は、付勢力を放出してリッド３を中立位置から開位置に向けて付勢する。
さらに換言すると、実施例１の回動構造体においては、ユーザーがリッド３を閉位置から中立位置にまで回動させることによって付勢部材５に付勢力が蓄積される。そして、ここで蓄積された付勢力によって、リッド３は中立位置から開位置にまで付勢される。 When the lid 3 is further rotated from the neutral position toward the open position against the urging force of the urging member 5, the input section 53 gets over the inflection section 40i. Then, the pressing force of the sliding contact portion 4 against the input portion 53 decreases. Then, the urging member 5 releases the urging force so that the pressing force of the sliding contact portion 4 becomes smaller, that is, the sliding contact portion 4 is moved from the pressing position shown in FIG. 6 toward the opening release position shown in FIG. Press. In other words, at this time, the urging member 5 releases the urging force to urge the lid 3 from the neutral position toward the open position.
In other words, in the rotating structure according to the first embodiment, the urging force is accumulated in the urging member 5 when the user rotates the lid 3 from the closed position to the neutral position. The lid 3 is biased from the neutral position to the open position by the biasing force accumulated here.

リッド３を開位置から中立位置に向けて回動させると、リッド３の一部を構成する摺接部４もまた、図７に示す開解除位置から図８に示す押圧位置に向けて回動する。このときにもまた、入力部５３に対する摺接部４の押圧力は徐々に大きくなるため、付勢部材５には付勢力が蓄積される。特に、このとき、主として第２湾曲部５２が閉じる方向に変形し、付勢部材５には付勢力が蓄積される。そしてこのとき付勢部材５の付勢力により、リッド３は開位置に向けて付勢される。 When the lid 3 is rotated from the open position toward the neutral position, the sliding contact portion 4 constituting a part of the lid 3 is also rotated from the open release position shown in FIG. 7 toward the pressing position shown in FIG. To do. Also at this time, the urging force is accumulated in the urging member 5 because the pressing force of the sliding contact portion 4 against the input portion 53 gradually increases. In particular, at this time, the second bending portion 52 is mainly deformed in the closing direction, and the urging force is accumulated in the urging member 5. At this time, the lid 3 is urged toward the open position by the urging force of the urging member 5.

付勢部材５の付勢力に抗してリッド３を中立位置からさらに閉位置に向けて回動させると、入力部５３は変曲部４０ｉを乗り越え、付勢部材５は摺接部４を図９に示す閉解除位置に向けて押圧する。その結果、リッド３は付勢部材５によって中立位置から閉位置に向けて付勢される。
つまり、実施例１の回動構造体においては、ユーザーがリッド３を開位置から中立位置にまで回動させることによって付勢部材５に付勢力が蓄積され、ここで蓄積された付勢力によってリッド３は中立位置から閉位置にまで付勢される。 When the lid 3 is further rotated from the neutral position toward the closed position against the urging force of the urging member 5, the input portion 53 gets over the inflection portion 40 i, and the urging member 5 shows the sliding contact portion 4. Press toward the closing release position shown in FIG. As a result, the lid 3 is urged by the urging member 5 from the neutral position toward the closed position.
In other words, in the rotating structure according to the first embodiment, the urging force is accumulated in the urging member 5 when the user rotates the lid 3 from the open position to the neutral position, and the lid is generated by the accumulated urging force. 3 is biased from the neutral position to the closed position.

外軸部３１には図略の二つのストッパが設けられている。一方のストッパである開ストッパは、リッド３が開位置にあるときに、ケース１に設けられている図略の開ストッパ受けと係合する。開ストッパと開ストッパ受けとが係合することで、開方向に向けたリッド３の回動が停止し、リッド３は開位置に留まる。開ストッパと開ストッパ受けとの係合は、リッド３が開位置以外の位置にあるときには解除される。
他方のストッパである閉ストッパは、リッド３が閉位置にあるときに、ケース１に設けられている図略の閉ストッパ受けと係合する。閉ストッパと閉ストッパ受けとが係合することで、閉方向に向けたリッド３の回動が停止し、リッド３は閉位置に留まる。閉ストッパと閉ストッパ受けとの係合は、リッド３が閉位置以外の位置にあるときには解除される。 The outer shaft portion 31 is provided with two stoppers (not shown). One stopper, which is one stopper, engages with an unillustrated open stopper receiver provided in the case 1 when the lid 3 is in the open position. When the opening stopper and the opening stopper receiver are engaged, the rotation of the lid 3 in the opening direction is stopped, and the lid 3 remains in the open position. The engagement between the open stopper and the open stopper receiver is released when the lid 3 is in a position other than the open position.
The other stopper, which is a stopper, engages with a not-shown closing stopper receiver provided in the case 1 when the lid 3 is in the closed position. When the closing stopper and the closing stopper receiver are engaged, the rotation of the lid 3 in the closing direction is stopped, and the lid 3 remains in the closed position. The engagement between the closed stopper and the closed stopper receiver is released when the lid 3 is in a position other than the closed position.

ところで、上述したように、リッド３が開位置と閉位置との間を回動する間、付勢部材５の入力部５３と摺接部４の外周面４０とが弾接する。このため、このリッド３の回動に伴って入力部５３と摺接部４の外周面４０とは摺接する。実施例１の回動構造体においては、摺接部４は繊維強化樹脂により構成されており比較的高硬度であるが、付勢部材５は板バネからなりさらに高硬度であるため、付勢部材５によって摺接部４が削られる場合がある。つまり、実施例１の回動構造体においても、リッド３が回動する際に摺接部４の削り屑が生じる場合がある。 As described above, while the lid 3 rotates between the open position and the closed position, the input portion 53 of the biasing member 5 and the outer peripheral surface 40 of the sliding contact portion 4 are in elastic contact. For this reason, the input part 53 and the outer peripheral surface 40 of the sliding contact part 4 are in sliding contact with the rotation of the lid 3. In the rotating structure of the first embodiment, the sliding contact portion 4 is made of fiber reinforced resin and has a relatively high hardness. However, the biasing member 5 is made of a leaf spring and has a higher hardness. The sliding contact portion 4 may be scraped by the member 5. That is, even in the rotating structure of the first embodiment, shavings of the sliding contact portion 4 may be generated when the lid 3 rotates.

しかし、図３および図４に示すように、実施例１の回動構造体においては、回収部４１における開口４１ｏの縁部４１ｅは、回動軸３５の周方向に対して交差する方向に延びている。したがって、リッド３が回動し、摺接部４の摺接領域４０ａと入力部５３とが摺接する際には、当該摺接領域４０ａに設けられた開口４１ｏの縁部４１ｅが入力部５３に当接する。開口４１ｏの縁部４１ｅは、回動軸３５の周方向、つまり、摺接部４に対する入力部５３の相対的な移動方向に対して交差する方向に延びている。このため、縁部４１ｅは入力部５３に対して、入力部５３の相対移動方向と交差する方向に摺接する。このため、例え付勢部材５の入力部５３によって摺接部４が削られ、その削り屑が付勢部材５の入力部５３に付着した場合にも、入力部５３に付着した削り屑は開口４１ｏの縁部４１ｅによって掻き取られる。また、縁部４１ｅは、入力部５３の相対移動方向に対して交差する方向に延びているため、縁部４１ｅは入力部５３に対して比較的大きな領域にわたって摺接する。このため、入力部５３に付着した削り屑は開口４１ｏの縁部４１ｅによって広範囲にわたって掻き取られる。 However, as shown in FIGS. 3 and 4, in the rotating structure according to the first embodiment, the edge 41 e of the opening 41 o in the collection unit 41 extends in a direction intersecting the circumferential direction of the rotating shaft 35. ing. Therefore, when the lid 3 rotates and the sliding contact area 40 a of the sliding contact portion 4 and the input section 53 are in sliding contact, the edge 41 e of the opening 41 o provided in the sliding contact area 40 a is connected to the input section 53. Abut. The edge 41 e of the opening 41 o extends in the circumferential direction of the rotation shaft 35, that is, in the direction intersecting the relative movement direction of the input unit 53 with respect to the sliding contact portion 4. For this reason, the edge part 41e is slidably contacted with the input part 53 in a direction crossing the relative movement direction of the input part 53. For this reason, even if the sliding contact portion 4 is shaved by the input portion 53 of the biasing member 5 and the shavings adhere to the input portion 53 of the biasing member 5, the shavings attached to the input portion 53 is opened. It is scraped off by the edge 41e of 41o. Further, since the edge portion 41 e extends in a direction intersecting the relative movement direction of the input portion 53, the edge portion 41 e is in sliding contact with the input portion 53 over a relatively large area. For this reason, the shavings adhering to the input part 53 are scraped over a wide range by the edge part 41e of the opening 41o.

特に、実施例１の回動構造体においては、縁部４１ｅの全体が回動軸３５の周方向に対して交差しているため、縁部４１ｅは入力部５３の相対移動方向に対して常に交差する方向に摺接する。つまり開口４１ｏの縁部４１ｅは入力部５３に対して非常に大きな領域にわたって摺接するため、入力部５３に付着した削り屑は開口４１ｏの縁部４１ｅによって満遍なく掻き取られる。掻き取られた削り屑は回収部４１に回収される。
よって、実施例１の回動構造体によると、付勢部材５への削り屑の付着が抑制され、入力部５３と摺接部４との間、つまり、付勢部材５とリッド３との間に削り屑が挟まり難い。よって実施例の回動構造体によると、削り屑による異音の発生を抑制できる。 In particular, in the rotating structure according to the first embodiment, since the entire edge portion 41 e intersects the circumferential direction of the rotating shaft 35, the edge portion 41 e is always in the relative movement direction of the input portion 53. Sliding in the intersecting direction. That is, since the edge 41e of the opening 41o is in sliding contact with the input portion 53 over a very large area, the shavings adhering to the input portion 53 is evenly scraped off by the edge 41e of the opening 41o. The scraped scraps are collected by the collection unit 41.
Therefore, according to the rotating structure of the first embodiment, the attachment of shavings to the urging member 5 is suppressed, and between the input portion 53 and the sliding contact portion 4, that is, between the urging member 5 and the lid 3. It is difficult to get swarf between them. Therefore, according to the rotating structure of the embodiment, generation of abnormal noise due to shavings can be suppressed.

なお、開口４１ｏの縁部４１ｅと付勢部材５の入力部５３との摺接箇所においては、比較的大きな摺動抵抗が生じると考えられる。この摺動抵抗を低減するためには、縁部４１ｅと入力部５３とが摺接する角度を、互いに平行となる角度つまり０°に近い角度にするのが良いと考えられる。図４に示す摺動部の展開図上においては、開口４１ｏの縁部４１ｅは曲線Ｗ０で表され、入力部５３の相対移動方向、つまり、回動軸３５の周方向は直線Ｌ０で表される。
縁部４１ｅと入力部５３との摺動抵抗低減のため、縁部４１ｅと入力部５３とが摺接する角度を平行に近づけるためには、曲線Ｗ０の接線Ｌ１と直線Ｌ０とのなす角θを０°に近づければ良いと考えられる。しかし既述したように、入力部５３に付着した削り屑を縁部４１ｅによって掻き取るためには、角θは０°を超える必要があると考えられる。よって、角θの大きさには好ましい範囲が存在すると考えられる。本発明の回動構造体においては、角θは０°を超え５５°以下であるのが良いと考えられる。より好ましくは、角θは５°以上４５°以下であるのが良いと考えられる。縁部４１ｅは、角θがこのような範囲に収まるように湾曲した部分を有するのが好ましく、縁部４１ｅの全体が角θがこのような範囲に収まるように湾曲しているのがより好ましい。なお、ここで言う接線Ｌ１と直線Ｌ０とのなす角θとは、接線Ｌ１と直線Ｌ０との二つの交差角の中で劣角の方を指す。 In addition, it is thought that a comparatively large sliding resistance arises in the sliding contact location of the edge part 41e of the opening 41o, and the input part 53 of the biasing member 5. FIG. In order to reduce this sliding resistance, the angle at which the edge portion 41e and the input portion 53 are in sliding contact with each other is considered to be an angle that is parallel to each other, that is, an angle close to 0 °. In the developed view of the sliding portion shown in FIG. 4, the edge 41e of the opening 41o is represented by a curve W0, and the relative movement direction of the input portion 53, that is, the circumferential direction of the rotating shaft 35 is represented by a straight line L0. The
In order to reduce the sliding resistance between the edge portion 41e and the input portion 53, in order to bring the angle at which the edge portion 41e and the input portion 53 are in sliding contact with each other, the angle θ formed between the tangent line L1 and the straight line L0 of the curve W0 is set. It is considered that it should be close to 0 °. However, as described above, it is considered that the angle θ needs to exceed 0 ° in order to scrape off the shavings adhering to the input portion 53 by the edge portion 41e. Therefore, it is considered that there is a preferable range for the magnitude of the angle θ. In the rotating structure of the present invention, the angle θ is considered to be better than 0 ° and 55 ° or less. More preferably, the angle θ is considered to be 5 ° or more and 45 ° or less. The edge portion 41e preferably has a curved portion so that the angle θ falls within such a range, and the entire edge portion 41e more preferably curves so that the angle θ falls within such a range. . Here, the angle θ formed by the tangent line L1 and the straight line L0 refers to the inferior one of the two crossing angles between the tangent line L1 and the straight line L0.

また、付勢部材５に付勢力を蓄積してリッド３を付勢する必要上、回収部４１の開口４１ｏは摺接部４における摺接領域４０ａの一部を占めるに留める必要がある。つまり、摺接領域４０ａには、開口４１ｏのない領域を設ける必要がある。本発明の回動構造体において、摺接領域４０ａは、当該開口４１ｏのない領域を一部に有すれば良いが、摺接部４の強度を充分に保つ必要上、開口４１ｏのない領域は摺接領域４０ａの２０％以上を占めるのが好ましく、３０％〜９５％の範囲であるのがより好ましく、４０％〜８０％の範囲であるのがさらに好ましい。 Further, in order to urge the lid 3 by accumulating the urging force in the urging member 5, the opening 41 o of the recovery part 41 needs to occupy a part of the slidable contact area 40 a in the slidable contact part 4. That is, it is necessary to provide a region without the opening 41o in the sliding contact region 40a. In the rotating structure of the present invention, the sliding contact area 40a may have a part of the area without the opening 41o. However, the area without the opening 41o is required to sufficiently maintain the strength of the sliding contact part 4. It preferably occupies 20% or more of the sliding contact region 40a, more preferably in the range of 30% to 95%, and still more preferably in the range of 40% to 80%.

削り屑は、溝状をなす回収部４１に入り込み当該回収部４１に回収され得る。回収部４１に削り屑が回収されることによっても、入力部５３と摺接部４との間、つまり、付勢部材５とリッド３との間に削り屑が挟まり難くなり、上記した異音の発生が抑制される。また、実施例１の回動構造体においては、回収部４１に潤滑剤が入っている。このため一旦回収部４１に回収された削り屑は潤滑剤によって回収部４１内に捉えられ、外部に脱落し難い。
なお、当然乍ら、潤滑剤によって摺接部４の摺接領域４０ａと付勢部材５の入力部５３との間の摺動抵抗が低減し、上記した削り屑が生じ難くなる利点もある。 The shavings can enter the collecting unit 41 having a groove shape and be collected by the collecting unit 41. Even when the scraps are collected in the collecting portion 41, the shavings are hardly caught between the input portion 53 and the sliding contact portion 4, that is, between the biasing member 5 and the lid 3, and the above-described abnormal noise is generated. Is suppressed. In the rotating structure according to the first embodiment, the recovery unit 41 contains a lubricant. For this reason, the shavings once collected in the collection unit 41 are caught in the collection unit 41 by the lubricant and are not easily dropped to the outside.
Needless to say, the sliding resistance between the sliding contact area 40a of the sliding contact portion 4 and the input portion 53 of the biasing member 5 is reduced by the lubricant, and there is an advantage that the above-mentioned shavings are less likely to occur.

さらに、実施例１の回動構造体において、回収部４１の開口４１ｏは、回動軸３５の周方向に対して交差している。このようにすることで、回収部４１の開口面積を充分に小さく保ったままで、摺接領域４０ａの軸方向に広い範囲に縁部４１ｅを設け得る。その結果、摺接領域４０ａにおける開口４１ｏ以外の領域、つまり入力部５３に摺接し得る領域を充分に確保しつつ、削り屑を回収部４１によって頻度高く回収できる。したがって、このことによっても上記した削り屑による異音の発生を抑制でき、かつ、リッド３を開閉駆動するのに充分な付勢力を付勢部材５に蓄積できる。 Furthermore, in the rotating structure according to the first embodiment, the opening 41 o of the collection unit 41 intersects the circumferential direction of the rotating shaft 35. By doing in this way, the edge part 41e can be provided in the wide range in the axial direction of the sliding contact area | region 40a, keeping the opening area of the collection | recovery part 41 small enough. As a result, shavings can be collected frequently by the collection unit 41 while ensuring a region other than the opening 41o in the sliding contact region 40a, that is, a region capable of sliding contact with the input unit 53. Therefore, it is possible to suppress the generation of abnormal noise due to the shavings as described above, and to accumulate a biasing force sufficient to open and close the lid 3 in the biasing member 5.

実施例１の回動構造体においては、Ｓ字の板バネからなる付勢部材５によってリッド３を開位置と閉位置との二つの位置に付勢している。このため、実施例１の回動構造体は、リッド３を開位置および／または閉位置にロックするロック機構を有さない。しかし、実施例１の回動構造体に、さらに、リッド３を開位置または閉位置にロックするロック機構を設けても良い。或いは、付勢部材５として、リッド３を一方向にのみ付勢するものを用い、さらに、付勢部材５が付勢する方向とは反対の方向に回動したリッド３をロックするロック機構を設けても良い。 In the rotating structure according to the first embodiment, the lid 3 is urged to two positions, ie, an open position and a closed position, by an urging member 5 formed of an S-shaped leaf spring. For this reason, the rotating structure of the first embodiment does not have a lock mechanism that locks the lid 3 in the open position and / or the closed position. However, a lock mechanism that locks the lid 3 in the open position or the closed position may be further provided in the rotating structure of the first embodiment. Alternatively, as the urging member 5, a member that urges the lid 3 only in one direction is used, and a lock mechanism that locks the lid 3 rotated in a direction opposite to the direction in which the urging member 5 is urged is used. It may be provided.

また、実施例１の回動構造体においては、付勢部材５が上記したＳ字の板バネであり、摺接部４が変曲部４０ｉを有し、かつ、回収部４１は変曲部４０ｉに対して線対称に配置されている。換言すると、回収部４１は変曲部４０ｉに対して回動軸３５の周方向において対称に配置されている。このことによって、開動作時にも、閉動作時にも、付勢部材５には略同じ大きさの付勢力が略同じタイミングで加わるため、一つの付勢部材５によってリッド３を開方向と閉方向との両方に安定して駆動できる利点がある。 In the rotating structure of the first embodiment, the urging member 5 is the S-shaped leaf spring, the sliding contact portion 4 has the inflection portion 40i, and the recovery portion 41 has the inflection portion. It is arranged symmetrically with respect to 40i. In other words, the collection part 41 is arranged symmetrically in the circumferential direction of the rotation shaft 35 with respect to the inflection part 40i. As a result, a biasing force of substantially the same magnitude is applied to the biasing member 5 at substantially the same timing both during the opening operation and during the closing operation, so that the lid 3 is opened and closed in one opening member 5. Both have the advantage of being able to drive stably.

実施例１の回動構造体においては、摺接部４の摺接領域４０ａは回動軸３５に隣接している。摺接領域４０ａと回動軸３５とをこのように配置することで、リッド３を付勢するための機構を回動軸３５付近に集約することができ、回動構造体をコンパクトにできる利点がある。なお、これは、本発明の回動構造体が、既述した従来のねじりコイルバネを用いた回動構造体とは異なり、摺接部４の摺接領域４０ａに弾性的に摺接する付勢部材５を用いたことにもよる。つまり、実施例１の回動構造体によると、従来広く用いられてきたものとは異なる付勢部材５を選択し、かつ、摺接部４の摺接領域４０ａを回動軸３５に隣接させたことにより、回動構造体のコンパクト化を実現できたとも言える。摺接領域４０ａに弾性的に摺接する付勢部材５としては、実施例１で挙げたＳ字状の板バネに限らず、その他の形状の板バネや圧縮コイルバネに代表される圧縮バネを挙げることができる。これらの付勢部材５によっても、リッド３を開位置または閉位置に付勢できる。換言すると、この場合にも本発明の回動構造体は、付勢部材５によって回動部材を第１位置または第２位置に付勢できる。また、摺接部４と付勢部材５との配置や形状、付勢部材５に蓄積し得る付勢力等によっては、Ｓ字状ではない圧縮バネを用いる場合にも、実施例１の回動構造体と同様に、回動部材を第１位置および第２位置に付勢することも可能である。 In the rotating structure of the first embodiment, the sliding contact area 40 a of the sliding contact portion 4 is adjacent to the rotating shaft 35. By arranging the sliding contact area 40a and the rotation shaft 35 in this way, the mechanism for biasing the lid 3 can be concentrated in the vicinity of the rotation shaft 35, and the rotation structure can be made compact. There is. Note that this is different from the conventional rotating structure using the torsion coil spring in which the rotating structure of the present invention is elastically slidably contacted with the sliding contact area 40a of the sliding contact portion 4.
