Description

本発明は、第1部材に対して回動する第2部材を持ち、第2部材の第1部材に対する回動位置を、第2部材の回動範囲の一部で無段階的に一時固定できる回動装置に関する。   The present invention has a second member that rotates relative to the first member, and the rotation position of the second member relative to the first member can be temporarily fixed steplessly within a part of the rotation range of the second member. The present invention relates to a rotating device.

第1部材に対して回動する第2部材を持つ回動装置としては、従来から種々のものが知られている。例えば、車両用のコンソールボックスは、ケース体(第1部材)に対して回動するリッド(第2部材)を持つ。この種の回動装置のなかには、調整部によって、第2部材の第1部材に対する回動角度を、第2部材の回動範囲の一部で無段階的に一時固定できるようにしたものがある(例えば、特許文献1参照)。   Various types of rotating devices having a second member that rotates with respect to the first member have been known. For example, a console box for a vehicle has a lid (second member) that rotates with respect to a case body (first member). Among these types of rotation devices, there is one in which the adjustment unit can temporarily fix the rotation angle of the second member relative to the first member steplessly within a part of the rotation range of the second member. (For example, refer to Patent Document 1).

特許文献1に紹介されている回動装置は、ブラケットの一部と制動部材とからなる第2部材調節部を持つ。詳しくは、第1部材と第2部材との一方に取り付けられている制動部材を、第1部材と第2部材との他方に取り付けられているブラケットに摺動させることによって、第1部材の第2部材に対する回動角度を無段階的に一時固定する。ところで特許文献1の回動装置においては、ブラケットに摺動面を設けているが、ブラケットは成形時に曲げ加工をおこなう必要があるために、比較的軟質な材料からなる。このため、ブラケットにおける摺動面の耐久性を高めることは困難であり、長期間使用した際には摺動面が摩耗する。このため、ブラケットの摺動面と制動部材との摺動抵抗を一定の大きさに保ち難い。このため、第2部材の第1部材に対する回動角度を安定して一時固定できず、回動装置が安定して動作し難くなる可能性がある。   The rotating device introduced in Patent Document 1 has a second member adjusting portion made up of a part of a bracket and a braking member. Specifically, by sliding a braking member attached to one of the first member and the second member to a bracket attached to the other of the first member and the second member, the first member The rotation angle with respect to the two members is temporarily fixed steplessly. By the way, in the rotation apparatus of patent document 1, although the sliding surface is provided in the bracket, since a bracket needs to be bent at the time of shaping | molding, it consists of a comparatively soft material. For this reason, it is difficult to increase the durability of the sliding surface of the bracket, and the sliding surface is worn when used for a long time. For this reason, it is difficult to keep the sliding resistance between the sliding surface of the bracket and the braking member constant. For this reason, the rotation angle of the second member relative to the first member cannot be stably temporarily fixed, and the rotation device may not be stably operated.

さらに、特許文献1に紹介されている回動装置においては、摺動面に連絡するテーパ溝をブラケットに設け、制動部材に設けた突部をテーパ溝から摺動面に導くことで、摺動抵抗を徐々に大きくしている。しかし、ブラケットに設けた摺動面と同様に、ブラケットに設けたテーパ溝もまた耐久性に劣る。テーパ溝が摩耗すると、回動装置がガタつく。このことによっても、特許文献1に紹介されている回動装置は、安定して動作し難い問題があった。   Furthermore, in the rotating device introduced in Patent Document 1, a taper groove that communicates with the sliding surface is provided in the bracket, and a protrusion provided on the braking member is guided from the taper groove to the sliding surface to slide. The resistance is gradually increased. However, like the sliding surface provided on the bracket, the tapered groove provided on the bracket is also inferior in durability. When the taper groove is worn, the rotating device rattles. For this reason as well, the rotating device introduced in Patent Document 1 has a problem that it is difficult to operate stably.

さらに、特許文献1に紹介されている回動装置は、ブラケットを第2部材調節部の一部として用いているため、他の回動装置に第2部材調節部を流用し難い。このため、特許文献1に紹介されている回動装置は、安価に製造し難い問題もある。   Furthermore, since the rotating device introduced in Patent Document 1 uses the bracket as a part of the second member adjusting portion, it is difficult to divert the second member adjusting portion to other rotating devices. For this reason, the rotating device introduced in Patent Document 1 also has a problem that it is difficult to manufacture at a low cost.

したがって、安定して動作し、かつ安価に製造できる回動装置が求められている。   Therefore, there is a need for a rotating device that operates stably and can be manufactured at low cost.

本発明の回動装置においては、第2部材の回動範囲の一部で第2部材を無段階的に一時固定する(以下単に、第2部材を一時固定する、と呼ぶ)ための機構として、金属製の3つのワッシャーからなる第2部材調節部を用いている。詳しくは、第2部材調節部は、入力ワッシャーとブレーキワッシャーと付勢ワッシャーとからなる。入力ワッシャーは第2部材に固定されて第2部材とともに回動する。ブレーキワッシャーは入力ワッシャーに対して相対的に回動する。付勢ワッシャーはブレーキワッシャーを入力ワッシャーに向けて付勢する。入力ワッシャーは、凸面である入力当て面と、入力当て面よりも突出高さの小さい入力一般面とを持つ。ブレーキワッシャーは、凸面であるブレーキ当て面と、ブレーキ当て面よりも突出高さの小さいブレーキ一般面とを持つ。入力当て面およびブレーキ一般面は、入力ワッシャーのなかでブレーキワッシャー側の面に形成されている。このため、第2部材が第3位置と第2位置との間を回動する際には、付勢ワッシャーの付勢力によって、入力当て面とブレーキ当て面とが互いに圧接する。入力当て面とブレーキ当て面とが圧接することで、入力ワッシャーとブレーキワッシャーとの摺動抵抗が高まり、入力ワッシャーのブレーキワッシャーに対する回動が一時停止する。このため、入力ワッシャーに固定されている第2部材もまた、回動を一時停止する。入力ワッシャーとブレーキワッシャーとの摺動抵抗に抗して第2部材に回動方向の力を加えると、第2部材は第2位置または第1位置方向に回動する。よって、本発明の回動装置によると、第2部材の回動範囲の一部(すなわち、第3位置と第2位置との間)で第2部材を無段階的に一時固定できる。   In the rotating device of the present invention, as a mechanism for temporarily fixing the second member steplessly in a part of the rotation range of the second member (hereinafter simply referred to as temporarily fixing the second member). The second member adjusting portion composed of three metal washers is used. Specifically, the second member adjusting portion includes an input washer, a brake washer, and an urging washer. The input washer is fixed to the second member and rotates together with the second member. The brake washer rotates relative to the input washer. The biasing washer biases the brake washer toward the input washer. The input washer has an input contact surface that is a convex surface, and an input general surface that is smaller in projection height than the input contact surface. A brake washer has a brake contact surface which is a convex surface, and a brake general surface whose protrusion height is smaller than that of the brake contact surface. The input contact surface and the general brake surface are formed on the surface on the brake washer side in the input washer. For this reason, when the second member rotates between the third position and the second position, the input contact surface and the brake contact surface are pressed against each other by the urging force of the urging washer. The pressure contact between the input contact surface and the brake contact surface increases the sliding resistance between the input washer and the brake washer, and the rotation of the input washer with respect to the brake washer is temporarily stopped. For this reason, the second member fixed to the input washer also temporarily stops rotating. When a force in the rotation direction is applied to the second member against the sliding resistance between the input washer and the brake washer, the second member rotates in the second position or the first position direction. Therefore, according to the rotating device of the present invention, the second member can be temporarily fixed steplessly within a part of the rotation range of the second member (that is, between the third position and the second position).

本発明の回動装置によると、第2部材を一時固定するための第2部材調節部として、金属製の3つのワッシャーを用いている。ワッシャーは、上述したブラケットとは異なり、大きな曲げ加工を必要としない。このため、ワッシャーの材料としては硬質な金属材料を選択できる。よって、本発明の回動装置によると、第2部材調節部の耐久性を向上させ、入力当て面およびブレーキ当て面の摩耗を抑制できる。よって、本発明の回動装置によると、入力当て面とブレーキ当て面との摺動抵抗を一定の大きさに保ち易く、第2部材を安定して動作させることができる。   According to the rotating device of the present invention, three metal washers are used as the second member adjusting portion for temporarily fixing the second member. Unlike the bracket described above, the washer does not require a large bending process. For this reason, a hard metal material can be selected as the material of the washer. Therefore, according to the rotating device of the present invention, it is possible to improve the durability of the second member adjusting portion and to suppress the wear of the input contact surface and the brake contact surface. Therefore, according to the rotating device of the present invention, the sliding resistance between the input contact surface and the brake contact surface can be easily maintained at a constant magnitude, and the second member can be operated stably.

さらに、第2部材調節部が3つのワッシャーのみからなるため、同一の第2部材調節部を様々な回動装置に転用できる。このため、第2部材調節部に要するコストを低減でき、回動装置の製造コストを低減できる利点もある。   Furthermore, since the second member adjusting portion is composed of only three washers, the same second member adjusting portion can be diverted to various rotating devices. For this reason, the cost which a 2nd member adjustment part requires can be reduced, and there also exists an advantage which can reduce the manufacturing cost of a rotation apparatus.

さらに、第2部材に対する入力ワッシャーの取り付け角度を調整すれば、第2部材が第1位置に配置されたときの入力当て面とブレーキ当て面との相対位置を調整でき、第2部材が第1位置から第3位置まで回動する角度を容易に変更できる。このため、第2部材が自動的に回動する角度(すなわち、第2部材が第2部材付勢手段によって付勢される回動角度)を容易に変更できる利点もある。   Furthermore, if the attachment angle of the input washer with respect to the second member is adjusted, the relative position between the input contact surface and the brake contact surface when the second member is disposed at the first position can be adjusted, and the second member is the first member. The angle of rotation from the position to the third position can be easily changed. For this reason, there is also an advantage that the angle at which the second member automatically rotates (that is, the rotation angle at which the second member is urged by the second member urging means) can be easily changed.

2つの入力一般面67は略平面の扇面状をなす。2つの入力一般面67は入力ワッシャー60の周方向に離間している。2つの入力当て面66は、略平面の扇面状をなし、右方に突出している。したがって、各入力一般面67の突出高さは各入力当て面66の突出高さよりも小さい。換言すると、各入力当て面66は各入力一般面67よりも右方に配置されている。各入力当て面66は入力ワッシャー60の周方向に離間し、それぞれ、2つの入力一般面67の間に配置されている。各入力当て面66とその時計回りの先側に配置されている各入力一般面67とは、それぞれ、第1傾斜面68で滑らかに接続されている。2つの第1固定凸部69は、左方に突出する凸状をなし、各入力一般面67にそれぞれ1つずつ配置されている。各第1固定凸部69は、それぞれ、第2部材2の第2左軸保持孔16の外周側に形成されている第1固定凹部70に嵌合する。したがって入力ワッシャー60は、第2部材2に固定され、回動軸部4を中心として第2部材2とともに回動する。   The two input general surfaces 67 have a substantially flat fan shape. The two input general surfaces 67 are separated from each other in the circumferential direction of the input washer 60. The two input contact surfaces 66 have a substantially flat fan shape and protrude rightward. Therefore, the protruding height of each input general surface 67 is smaller than the protruding height of each input contact surface 66.

Each input contact surface 66 is spaced apart in the circumferential direction of the input washer 60, and is disposed between the two input general surfaces 67. Each input contact surface 66 and each input general surface 67 arranged on the clockwise front side are smoothly connected by a first inclined surface 68.

2つのブレーキ一般面73は略平面の扇面状をなす。2つのブレーキ一般面73はブレーキワッシャー61の周方向に離間している。2つのブレーキ当て面72は、略平面の扇面状をなし、左方に突出している。したがって、各ブレーキ一般面73の突出高さは各ブレーキ当て面72の突出高さよりも小さい。換言すると、各ブレーキ当て面72は各ブレーキ一般面73よりも左方に配置されている。各ブレーキ当て面72の周方向の長さは、各入力当て面66の周方向の長さよりも長い。各ブレーキ当て面72はブレーキワッシャー61の周方向に離間し、それぞれ、2つのブレーキ一般面73の間に配置されている。各ブレーキ当て面72とその反時計回りの先側に配置されている各ブレーキ一般面73とは、第2傾斜面74で滑らかに接続されている。2つの第2固定凹部75は、右方に開口する孔状をなし、各ブレーキ一般面73にそれぞれ1つずつ配置されている。   The two brake general surfaces 73 have a substantially flat fan shape. The two brake general surfaces 73 are separated from each other in the circumferential direction of the brake washer 61. The two brake contact surfaces 72 have a substantially flat fan shape and protrude to the left. Therefore, the protrusion height of each brake general surface 73 is smaller than the protrusion height of each brake contact surface 72. In other words, each brake contact surface 72 is disposed to the left of each brake general surface 73. The circumferential length of each brake contact surface 72 is longer than the circumferential length of each input contact surface 66. Each brake contact surface 72 is spaced apart in the circumferential direction of the brake washer 61 and is disposed between the two brake general surfaces 73.

ケース体13と第3部材3との間には、図略の第3部材ロック手段が設けられている。第3部材3は、閉位置にまで回動すると、第3部材ロック手段によってケース体13に対してロックされる。また、第3部材3と蓋本体20との間には、図略の第2部材ロック手段が設けられている。第2部材2および蓋本体20は、第3部材3が閉位置にまで回動している状態で閉位置にまで回動すると、第2部材ロック手段によって第2部材2に対してロックされる。このとき、第3部材3は閉位置にまで回動しているため、第2部材2は閉位置でロックされる。なお、第3部材3は第2部材2に対してロックされるため、第2部材2が回動すると、第2部材2とともに回動する。   Between the case body 13 and the third member 3, third member locking means (not shown) is provided. When the third member 3 is rotated to the closed position, the third member 3 is locked to the case body 13 by the third member locking means. Further, a second member locking means (not shown) is provided between the third member 3 and the lid main body 20. When the second member 2 and the lid body 20 are rotated to the closed position while the third member 3 is rotated to the closed position, the second member 2 and the lid main body 20 are locked to the second member 2 by the second member locking means. . At this time, since the third member 3 is rotated to the closed position, the second member 2 is locked at the closed position. Since the third member 3 is locked with respect to the second member 2, the third member 3 rotates together with the second member 2 when the second member 2 rotates.

以下、実施例1の回動装置の動作を説明する。   Hereinafter, the operation of the rotating device according to the first embodiment will be described.

図2に示すように第2部材2および第3部材3が閉位置にロックされている状態では、図9に示すように、入力ワッシャー60の入力当て面66とブレーキワッシャー61のブレーキ一般面73とが対面し、入力ワッシャー60の入力一般面67とブレーキワッシャー61のブレーキ当て面72とが対面する。このとき付勢ワッシャー62は、ブレーキワッシャー61を入力ワッシャー60方向に付勢しないか僅かに付勢するだけであり、入力ワッシャー60とブレーキワッシャー61とは相対的に回動可能である。   In the state where the second member 2 and the third member 3 are locked in the closed position as shown in FIG. 2, the input contact surface 66 of the input washer 60 and the brake general surface 73 of the brake washer 61 are shown in FIG. 9. And the input general surface 67 of the input washer 60 and the brake contact surface 72 of the brake washer 61 face each other. At this time, the urging washer 62 does not urge the brake washer 61 in the direction of the input washer 60 or only slightly urges it, and the input washer 60 and the brake washer 61 are relatively rotatable.

第2部材2および第3部材3が閉位置にロックされている状態で、第2部材ロック手段を解除操作すると、第2部材2は第2部材付勢手段5の付勢力によって開位置に向けて自動的に回動する。すると、第2部材2とともに回動した入力ワッシャー60が、ブレーキワッシャー61に対しても相対的に回動する。入力ワッシャー60が所定角度回動すると、図10に示すように、入力当て面66とブレーキ当て面72とが隣接し、第1傾斜面68と第2傾斜面74とが対面する。第1傾斜面68と第2傾斜面74とは相補的な形状をなすため、第1傾斜面68と第2傾斜面74との摩擦抵抗によって入力ワッシャー60の回動が停止する。すると、入力ワッシャー60に固定されている第2部材2もまた回動を停止し、図3に示す半開位置に一時固定される。   When the second member locking means is released while the second member 2 and the third member 3 are locked in the closed position, the second member 2 is directed to the open position by the urging force of the second member urging means 5. Rotate automatically. Then, the input washer 60 rotated together with the second member 2 also rotates relative to the brake washer 61. When the input washer 60 rotates by a predetermined angle, as shown in FIG. 10, the input contact surface 66 and the brake contact surface 72 are adjacent to each other, and the first inclined surface 68 and the second inclined surface 74 face each other. Since the first inclined surface 68 and the second inclined surface 74 have complementary shapes, the rotation of the input washer 60 is stopped by the frictional resistance between the first inclined surface 68 and the second inclined surface 74. Then, the second member 2 fixed to the input washer 60 also stops rotating and is temporarily fixed at the half-open position shown in FIG.

第2部材2が半開位置に一時固定されている状態で、ユーザーが第2部材2に手をかけ、第2部材2を更に開位置に向けて回動させると、図11に示すように、第1傾斜面68が第2傾斜面74を乗り越え、入力当て面66とブレーキ当て面72とが対面する。ブレーキワッシャー61は付勢ワッシャー62によって入力ワッシャー60方向に付勢されているため、入力当て面66とブレーキ当て面72とは強く圧接する。このため、第2部材2を半開位置と開位置との間に配置した状態でユーザーが第2部材2から手を離しても、入力当て面とブレーキ当て面との摩擦抵抗によって入力ワッシャー60はブレーキワッシャー61に対して一時固定され、入力ワッシャー60に固定されている第2部材2もまた一時固定される。第2部材2を開位置にまで回動させると、第2部材2に取り付けられているストッパ91が第1部材1に当接し、第2部材2の回動が停止する。   In a state where the second member 2 is temporarily fixed at the half-open position, when the user places a hand on the second member 2 and further rotates the second member 2 toward the open position, as shown in FIG. The first inclined surface 68 gets over the second inclined surface 74, and the input contact surface 66 and the brake contact surface 72 face each other. Since the brake washer 61 is biased in the direction of the input washer 60 by the biasing washer 62, the input contact surface 66 and the brake contact surface 72 are in strong pressure contact. For this reason, even if the user releases his hand from the second member 2 with the second member 2 disposed between the half-open position and the open position, the input washer 60 is caused by the frictional resistance between the input contact surface and the brake contact surface. The second member 2 that is temporarily fixed to the brake washer 61 and fixed to the input washer 60 is also temporarily fixed. When the second member 2 is rotated to the open position, the stopper 91 attached to the second member 2 comes into contact with the first member 1 and the rotation of the second member 2 is stopped.

第2部材2および第3部材3が閉位置にロックされている状態で、第3部材ロック手段を解除操作すると、第3部材3は第3部材付勢手段6の付勢力によって半開位置にまで自動的に回動する。すると、第3部材3とともに回動した第2入力ワッシャー85が、第2ブレーキワッシャー86に対しても相対的に回動する。第2入力ワッシャー85が所定角度回動すると、第2入力当て面と第2ブレーキ当て面とが隣接し、第2入力ワッシャー85の回動が停止する。すると、第2入力ワッシャー85に固定されている第3部材3もまた回動を停止し、図3に示す半開位置に一時固定される。   When the third member locking means is released while the second member 2 and the third member 3 are locked at the closed position, the third member 3 is moved to the half-open position by the urging force of the third member urging means 6. It rotates automatically. Then, the second input washer 85 rotated together with the third member 3 also rotates relative to the second brake washer 86. When the second input washer 85 rotates by a predetermined angle, the second input contact surface and the second brake contact surface are adjacent to each other, and the rotation of the second input washer 85 is stopped. Then, the third member 3 fixed to the second input washer 85 also stops rotating and is temporarily fixed at the half-open position shown in FIG.

第3部材3が半開位置に一時固定されている状態で、ユーザーが第3部材3に手をかけ、第3部材3を更に開位置に向けて回動させると、第2入力当て面と第2ブレーキ当て面とが第2付勢ワッシャー87の付勢力によっては強く圧接する。このため、第3部材3を半開位置と開位置との間に配置した状態でユーザーが第3部材3から手を離しても、第2入力ワッシャー85は第2ブレーキワッシャー86に対して一時固定され、第2入力ワッシャー85に固定されている第3部材3もまた一時固定される。第3部材3を開位置にまで回動させると、第2部材2に取り付けられているストッパが第1部材1に当接し、第2部材2の回動および第3部材3の回動が停止する。なお、第3部材3の回動角度は第2部材2の回動角度を超えない。このため、第2部材2の第3部材3に対するロックを解除し、第2部材2のみを先ず回動させている場合、第3部材3の回動角度が第2部材2の回動角度よりも小さいときには、第3部材3は独立して一時固定される。すなわち第3部材3は、第2入力ワッシャー85、第2ブレーキワッシャー86および第2付勢ワッシャー87からなる第3部材調節部8によって、反開位置と開位置との間で一時固定される。また、第3部材3の回動角度が第2部材2の回動角度よりも大きくなると、第3部材3は第3部材調節部8によって一時固定されるとともに、第2部材調節部7によって一時固定されている第2部材2によっても一時固定される。   In a state where the third member 3 is temporarily fixed at the half-open position, when the user places a hand on the third member 3 and further rotates the third member 3 toward the open position, the second input contact surface and the second input contact surface Depending on the urging force of the second urging washer 87, the two brake contact surfaces are strongly pressed against each other. For this reason, even if the user releases the hand from the third member 3 with the third member 3 disposed between the half-open position and the open position, the second input washer 85 is temporarily fixed to the second brake washer 86. The third member 3 fixed to the second input washer 85 is also temporarily fixed. When the third member 3 is rotated to the open position, the stopper attached to the second member 2 comes into contact with the first member 1, and the rotation of the second member 2 and the rotation of the third member 3 are stopped. To do. Note that the rotation angle of the third member 3 does not exceed the rotation angle of the second member 2. For this reason, when the lock | rock with respect to the 3rd member 3 of the 2nd member 2 is cancelled | released and only the 2nd member 2 is rotated first, the rotation angle of the 3rd member 3 is larger than the rotation angle of the 2nd member 2. Is smaller, the third member 3 is temporarily fixed independently. That is, the third member 3 is temporarily fixed between the counter-open position and the open position by the third member adjusting portion 8 including the second input washer 85, the second brake washer 86, and the second biasing washer 87. Further, when the rotation angle of the third member 3 becomes larger than the rotation angle of the second member 2, the third member 3 is temporarily fixed by the third member adjusting unit 8 and is temporarily set by the second member adjusting unit 7. It is also temporarily fixed by the fixed second member 2.

実施例1の回動装置は、第2部材2調節手段によって、第2部材2を半開位置と開位置との間で一時固定できる。また、第3部材3調節手段によって、第3部材3を半開位置と開位置との間で一時固定できる。   The rotating device of the first embodiment can temporarily fix the second member 2 between the half-open position and the open position by the second member 2 adjusting means. Further, the third member 3 can be temporarily fixed between the half-open position and the open position by the third member 3 adjusting means.

また、第2部材調節部7および第3部材調節部8は、それぞれ3つのワッシャーからなり、簡単な構造である。このため、実施例1の回動装置は安価に製造できる。第2部材調節部7および第3部材調節部8として同じ3つのワッシャーを用いていることによっても、実施例1の回動装置は安価に製造できる。   Further, each of the second member adjusting portion 7 and the third member adjusting portion 8 includes three washers and has a simple structure. For this reason, the rotation apparatus of Example 1 can be manufactured cheaply. Also by using the same three washers as the second member adjusting portion 7 and the third member adjusting portion 8, the rotating device of the first embodiment can be manufactured at low cost.

さらに、第2部材調節部7および第3部材調節部8をそれぞれ構成する3つのワッシャーは、打ち出し加工されてなり、大きな曲げ加工を要さずに製造できるため、第2部材調節部7および第3部材調節部8の材料としては比較的硬質な金属材料を選択できる。このため、第2部材調節部7および第3部材調節部8は摩耗し難い。よって、実施例1の回動装置における第2部材2および第3部材3は安定して動作する。換言すると、実施例1の回動装置は安定して動作する。   Furthermore, since the three washers constituting the second member adjusting portion 7 and the third member adjusting portion 8 are formed by punching and can be manufactured without requiring a large bending process, the second member adjusting portion 7 and the second member adjusting portion 7 A relatively hard metal material can be selected as the material of the three-member adjusting portion 8. For this reason, the 2nd member adjustment part 7 and the 3rd member adjustment part 8 do not wear easily. Therefore, the 2nd member 2 and the 3rd member 3 in the rotation device of Example 1 operate stably. In other words, the rotating device of the first embodiment operates stably.

さらに、第2部材調節部7および第3部材調節部8がそれぞれ3つのワッシャーのみからなるため、第2部材調節部7を第3部材調節部8に転用することもできるし、第2部材調節部7(または第3部材調節部8)を他の回動装置の第2部材2調整手段および/または第3部材調節部8として転用することもできる。このため、第2部材調節部7および第3部材調節部8に要するコストが大きく低減し、回動装置の製造コストもまた低減する。   Furthermore, since each of the second member adjusting portion 7 and the third member adjusting portion 8 is composed of only three washers, the second member adjusting portion 7 can be diverted to the third member adjusting portion 8, or the second member adjusting portion can be used. The portion 7 (or the third member adjusting portion 8) can be diverted as the second member 2 adjusting means and / or the third member adjusting portion 8 of another rotating device. For this reason, the cost which the 2nd member adjustment part 7 and the 3rd member adjustment part 8 require are reduced significantly, and the manufacturing cost of a rotation apparatus also reduces.

さらに、第2部材2に対する入力ワッシャー60の取り付け角度を調整すれば、第2部材2が第1位置に配置されたときの入力当て面66とブレーキ当て面72との相対位置を調整でき、第2部材2が閉位置から半開位置にまで回動する角度を容易に変更できる。例えば、入力ワッシャー60を、反時計回りに所定角度回動させた状態で第2部材2に取り付ければ、閉位置から半開位置までの回動角度を小さくできる。この場合には、第2部材2が自動的に回動する角度を容易に小さくできる。また、入力ワッシャー60を、時計回りに所定角度回動させた状態で第2部材2に取り付ければ、閉位置から半開位置までの回動角度を大きくできる。この場合には、第2部材2が自動的に回動する角度を容易に大きくできる。よって、実施例1の回動装置によると、第2部材2が自動的に回動する角度を容易に変更できる。同様に、第3部材3に対する第2入力ワッシャー85の取り付け角度を調整すれば、第3部材3が閉位置から半開位置にまで自動的に回動する角度を容易に変更できる。   Further, by adjusting the mounting angle of the input washer 60 with respect to the second member 2, the relative position between the input contact surface 66 and the brake contact surface 72 when the second member 2 is disposed at the first position can be adjusted. The angle at which the two members 2 rotate from the closed position to the half-open position can be easily changed. For example, if the input washer 60 is attached to the second member 2 in a state of being rotated counterclockwise by a predetermined angle, the rotation angle from the closed position to the half-open position can be reduced. In this case, the angle at which the second member 2 automatically rotates can be easily reduced. Further, if the input washer 60 is attached to the second member 2 in a state of being rotated clockwise by a predetermined angle, the rotation angle from the closed position to the half-open position can be increased. In this case, the angle at which the second member 2 automatically rotates can be easily increased. Therefore, according to the rotating device of the first embodiment, the angle at which the second member 2 automatically rotates can be easily changed. Similarly, if the attachment angle of the second input washer 85 with respect to the third member 3 is adjusted, the angle at which the third member 3 automatically rotates from the closed position to the half-open position can be easily changed.

さらに、実施例1の回動装置によると、第2部材調節部7と第3部材調節部8とを回動軸部4の両端にそれぞれ配置したことで、回動軸部4に加わる力を均等化できる。このことによっても、実施例1の回動装置は安定して動作する。   Further, according to the rotating device of the first embodiment, the second member adjusting portion 7 and the third member adjusting portion 8 are arranged at both ends of the rotating shaft portion 4, respectively, so that the force applied to the rotating shaft portion 4 is increased. Can be equalized. Also by this, the rotation apparatus of Example 1 operates stably.

さらに、付勢ワッシャー62の付勢当て面81をブレーキワッシャー61のブレーキ一般面73に対面させたことで、第2部材2を安定して一時固定できる。ブレーキ一般面73は略平面状をなすために、付勢ワッシャー62の付勢力がブレーキワッシャー61に均等に加わるためである。第3部材3もまた同様に、安定して一時固定される。   Furthermore, the second member 2 can be stably and temporarily fixed by causing the biasing contact surface 81 of the biasing washer 62 to face the brake general surface 73 of the brake washer 61. This is because the urging force of the urging washer 62 is equally applied to the brake washer 61 because the brake general surface 73 is substantially flat. Similarly, the third member 3 is also stably fixed temporarily.

(実施例2)
実施例2の回動装置は、第3部材、第3部材付勢手段、第3部材調節部、および第2スペーサ部を持たないこと、回動軸部が第2部材に固定されていること、および、入力ワッシャー、ブレーキワッシャーおよび付勢ワッシャーの形状以外は実施例1の回動装置と同じである。実施例2の回動装置における入力ワッシャーを模式的に表す斜視図を図12に示す。実施例2の回動装置におけるブレーキワッシャーを模式的に表す斜視図を図13に示す。実施例2の回動装置における付勢ワッシャーを模式的に表す斜視図を図14に示す。

The rotating device of the second embodiment does not have the third member, the third member urging means, the third member adjusting portion, and the second spacer portion, and the rotating shaft portion is fixed to the second member. The rotation device of the first embodiment is the same as the rotation device of the first embodiment except for the shapes of the input washer, the brake washer, and the biasing washer. FIG. 12 is a perspective view schematically showing an input washer in the rotating device of the second embodiment. FIG. 13 is a perspective view schematically showing a brake washer in the rotating device of the second embodiment. FIG. 14 is a perspective view schematically showing an urging washer in the rotating device of the second embodiment.

実施例2の回動装置における入力ワッシャー60は、第1回動中心部65の形状以外は実施例1の回動装置における入力ワッシャー60と同じものである。第1回動中心部65は、左軸端体41の外形と相補的な断面形状をなす。このため、入力ワッシャー60は、回動軸部4に対して回動不可能である。   The input washer 60 in the rotation device of the second embodiment is the same as the input washer 60 in the rotation device of the first embodiment except for the shape of the first rotation center portion 65. The first rotation center portion 65 has a cross-sectional shape complementary to the outer shape of the left shaft end body 41. For this reason, the input washer 60 cannot rotate with respect to the rotation shaft portion 4.

実施例2の回動装置におけるブレーキワッシャー61は、第2回動中心部71の形状以外は実施例1の回動装置におけるブレーキワッシャー61と同じものである。第2回動中心部71は、左軸端体41よりも大径かつ断面円形の貫通孔状をなす。実施例2の回動装置における付勢ワッシャー62は、第3回動中心部80の形状以外は実施例1の回動装置における付勢ワッシャー62と同じものである。第3回動中心部80は、左軸端体41よりも大径かつ断面円形の貫通孔状をなす。このため、ブレーキワッシャー61および付勢ワッシャー62は回動軸部4に対して回動可能であり、かつ、入力ワッシャー60に対して相対的に回動する。   The brake washer 61 in the rotation device of the second embodiment is the same as the brake washer 61 in the rotation device of the first embodiment except for the shape of the second rotation center portion 71. The second rotation center portion 71 has a through-hole shape having a larger diameter and a circular cross section than the left shaft end body 41. The biasing washer 62 in the rotation device of the second embodiment is the same as the biasing washer 62 in the rotation device of the first embodiment except for the shape of the third rotation center portion 80. The third rotation center portion 80 has a through hole shape having a larger diameter and a circular cross section than the left shaft end body 41. For this reason, the brake washer 61 and the urging washer 62 are rotatable with respect to the rotation shaft portion 4 and are relatively rotated with respect to the input washer 60.

実施例2の回動装置において、第2部材2が回動すると、第2部材2に固定されている入力ワッシャー60もまた回動する。このとき、第2部材2に固定されている回動軸部4もまた回動する。ブレーキワッシャー61および付勢ワッシャー62は回動軸部4に対して回動可能であるため、入力ワッシャー60に対して相対的に回動する。このため、第2部材2が半開位置と開位置の間を回動するときには、入力ワッシャー60の入力当て面66とブレーキワッシャー61のブレーキ当て面72とが圧接して、第2部材2が一時固定される。よって、実施例2の回動装置もまた、第2部材2を安定して一時固定できる。   In the rotating device according to the second embodiment, when the second member 2 rotates, the input washer 60 fixed to the second member 2 also rotates. At this time, the rotation shaft portion 4 fixed to the second member 2 also rotates. Since the brake washer 61 and the urging washer 62 are rotatable with respect to the rotation shaft portion 4, the brake washer 61 and the biasing washer 62 are rotated with respect to the input washer 60. Therefore, when the second member 2 rotates between the half-open position and the open position, the input contact surface 66 of the input washer 60 and the brake contact surface 72 of the brake washer 61 are in pressure contact with each other, and the second member 2 is temporarily moved. Fixed. Therefore, the rotation apparatus of Example 2 can also fix the 2nd member 2 stably stably.

なお、実施例1〜2の回動装置においては、入力ワッシャー60の第1固定凸部69を第2部材2の第1固定凹部70に嵌合させることで、入力ワッシャー60を第2部材2に固定したが、他の方法によって入力ワッシャー60を第2部材2に固定しても良い。例えば、接着、溶着、熱カシメ、インサート成形等の方法によって入力ワッシャー60を第2部材2に固定しても良い。第2入力ワッシャー85も同様に、種々の方法で第3部材3に固定できる。   In the rotating devices according to the first and second embodiments, the input washer 60 is moved to the second member 2 by fitting the first fixed protrusion 69 of the input washer 60 into the first fixed recess 70 of the second member 2. However, the input washer 60 may be fixed to the second member 2 by another method. For example, the input washer 60 may be fixed to the second member 2 by a method such as adhesion, welding, thermal caulking, or insert molding. Similarly, the second input washer 85 can be fixed to the third member 3 by various methods.

また、実施例1〜2の回動装置においては、付勢ワッシャー62をブレーキワッシャー61に固定したが、本発明の回動装置における付勢ワッシャー62は、ブレーキワッシャー61を入力ワッシャー60方向に付勢すれば良く、ブレーキワッシャー61に固定しなくても良い。   In the rotating devices of Examples 1 and 2, the urging washer 62 is fixed to the brake washer 61. However, the urging washer 62 in the rotating device of the present invention applies the brake washer 61 in the direction of the input washer 60. It is only necessary to support the brake washer 61.

また、実施例1〜2の回動装置においては、入力当て面66とブレーキ当て面72とを第1傾斜面68で滑らかに接続したが、入力当て面66とブレーキ当て面72とは段差状に接続しても良い。   In the rotating devices of Examples 1 and 2, the input contact surface 66 and the brake contact surface 72 are smoothly connected by the first inclined surface 68. However, the input contact surface 66 and the brake contact surface 72 are stepped. You may connect to.

本発明の回動装置は、第1部材に対して回動する第2部材を持つ種々の装置として利用できる。例えば、本発明の回動装置は、自動車用のコンソールボックス、グラブボックス、アームレスト等として好ましく利用できる。   The rotating device of the present invention can be used as various devices having a second member that rotates with respect to the first member. For example, the rotating device of the present invention can be preferably used as a console box, a grab box, an armrest, etc. for an automobile.
