Abstract

<P>PROBLEM TO BE SOLVED: To provide a damper mechanism of a one-way system which has a short idle running time before the damper begins to start an effective operation. <P>SOLUTION: A rack 16 fixed to an open-close member 20 and a meshing base member 24 are swingably fixed and gears 18, 38 are provided with the base member. By slidably holding the gear 18, can be meshed with and can be released from the gear 38. When the open-close member is opened, the gears 18 and 38 are meshed and when the opening and closing member is closed, and the gear 38 is released, by which torque communication through the damper is switched on or off so that the damper mechanism 14 is turned into the one-way system. Shortening the distance between the gears 18 and 38 enables the idle running time before the damper begins to start the effective operation faster. By this way, at the time of closing the opening and closing member, the damper can produce an effective operation by instantly meshing the gears 18 and 38 even if a motion is done to open the opening and closing member. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

本発明は、例えば車両のグローブボックスの開閉部材等に設けられ、開閉部材の開閉時に生ずる衝撃を緩衝するダンパー機構に関する。   The present invention relates to a damper mechanism that is provided, for example, in an opening / closing member of a glove box of a vehicle and cushions an impact generated when the opening / closing member is opened / closed.

従来のダンパー機構として、例えば、特許文献１では、図５（Ａ）に示すように、シリンダー１００内に、Ｏリング１０２を介してシリンダー１００の内壁面を摺動するピストン１０４が配設されている。   As a conventional damper mechanism, for example, in Patent Document 1, as shown in FIG. 5A, a piston 104 that slides on the inner wall surface of a cylinder 100 via an O-ring 102 is disposed in the cylinder 100. Yes.

また、シリンダー１００の先端には、環状のキャップ１０６が設けられており、キャップ１０６の内面側には曲面状のガイド面１０６Ａが形成されている。ここで、キャップ１０６とピストン１０４の間には、第１空間部１０８が設けられており、第１空間部１０８には圧縮スプリング１１０が配設されている。   An annular cap 106 is provided at the tip of the cylinder 100, and a curved guide surface 106A is formed on the inner surface side of the cap 106. Here, a first space 108 is provided between the cap 106 and the piston 104, and a compression spring 110 is disposed in the first space 108.

さらに、シリンダー１００の後端側には、中央部に空気の流通孔１１２が形成された区画壁１１４が形成されており、ピストン１０４と区画壁１１４とにより第２空間部１１６が設けられている。   Furthermore, a partition wall 114 having an air circulation hole 112 formed in the center is formed on the rear end side of the cylinder 100, and a second space 116 is provided by the piston 104 and the partition wall 114. .

また、シリンダー１００の後端部には、区画壁１１４との間に、第３空間部１１８が設けられており、この第３空間部１１８内にはバルブ１２０が設けられ、流通孔１１２を閉塞可能としている。このバルブ１２０の中心には、オリフィス１２２が形成されており、流通孔１１２及びオリフィス１２２を介して第２空間部１１６と第３空間部１１８とが連通している。   A third space 118 is provided at the rear end of the cylinder 100 between the partition wall 114 and a valve 120 is provided in the third space 118 to close the flow hole 112. It is possible. An orifice 122 is formed at the center of the valve 120, and the second space portion 116 and the third space portion 118 communicate with each other via the flow hole 112 and the orifice 122.

一方、ピストン１０４の第１空間部１０８側には、紐材１２４の一端部が取付けられており、紐材１２４の他端部はガイド面１０６Ａを通じて、グローブボックス１２６に設けられた連結部材１２８に連結されている。   On the other hand, one end portion of the string member 124 is attached to the first space 108 side of the piston 104, and the other end portion of the string member 124 is connected to the connecting member 128 provided in the glove box 126 through the guide surface 106A. It is connected.

以上のような構成により、グローブボックス１２６の閉止状態において、図示しないプッシュボタン式もしくはプルハンドル式のロックを解除すると、グローブボックス１２６は自重により開方向への回転モ−メントが働き、紐材１２４を引張り、圧縮スプリング１１０の付勢力に抗して、ピストン１０４を開方向（矢印方向）へ移動させ、紐材１２４はガイド面１０６Ａを介して引き出され、グローブボックス１２６が開き始める。   With the above-described configuration, when the push button type or pull handle type lock (not shown) is released in the closed state of the glove box 126, the glove box 126 rotates in the opening direction by its own weight, and the string material 124 The piston 104 is moved in the opening direction (arrow direction) against the urging force of the compression spring 110, the string member 124 is pulled out through the guide surface 106A, and the glove box 126 starts to open.

このとき、グローブボックス１２６は、オリフィス１２２による流動抵抗により、緩衝作用を受けつつ、グローブボックス１２６を開方向に開き、ピストン１０４は紐材１２４に引っ張られて開放位置まで移動する。   At this time, the glove box 126 opens the glove box 126 in the opening direction while receiving a buffering action due to the flow resistance by the orifice 122, and the piston 104 is pulled by the string member 124 and moves to the open position.

また、グローブボックス１２６の閉止動作においては、圧縮スプリング１１０の付勢力により開方向と逆方向にピストン１０４が移動すると共に、バルブ１２０が開放され、空気は流通孔１１２を通過可能となる。このため、ピストン１０４に掛かる負荷は低減された状態で、紐材１２４もシリンダー１００内に引き込まれ、グローブボックス１２６の閉止位置でグローブボックス１２６がロックされることとなる。
特開平５−７６８９４号公報 Further, in the closing operation of the glove box 126, the piston 104 moves in the direction opposite to the opening direction by the urging force of the compression spring 110, the valve 120 is opened, and the air can pass through the circulation hole 112. For this reason, in a state where the load applied to the piston 104 is reduced, the string member 124 is also drawn into the cylinder 100 and the glove box 126 is locked at the closed position of the glove box 126.
JP-A-5-76894

しかしながら、連結部材１２８はグローブボックス１２６の中央部側にあるため、グローブボックス１２６の自由端部と連結部材１２８の移動軌跡において、移動量の差が生じ、グローブボックス１２６の移動量に比べて、連結部材１２８の移動量は小さい。このため、ダンパーが効き始めるまでの空走距離が長くなってしまい、急な動作に追従できない場合もある。   However, since the connecting member 128 is on the center side of the glove box 126, there is a difference in the amount of movement in the movement trajectory of the free end of the glove box 126 and the connecting member 128, compared to the amount of movement of the glove box 126. The moving amount of the connecting member 128 is small. For this reason, the idling distance until the damper starts to work becomes long, and it may not be able to follow a sudden operation.

また、エアーダンパーの場合、温度変化によりシリンダー１００等の寸法が変化し、抵抗値がばらついたり、エアー洩れによってダンパーが効かなくなる恐れがある。一方、オイルダンパーの場合は、低温領域でオイルの粘性が上がるため、トルクが増大し、自重ではグローブボックス１２６が開放されない場合が懸念される。   Further, in the case of an air damper, the dimensions of the cylinder 100 and the like change due to temperature changes, and the resistance value may vary, or the damper may not work due to air leakage. On the other hand, in the case of an oil damper, since the viscosity of oil increases in a low temperature region, the torque increases, and there is a concern that the glove box 126 may not be opened by its own weight.

本発明は上記事実を考慮し、ダンパーが効き始めるまでの空走時間が短く、また、温度に拘らず、所定のダンパー効果が得られるワンウェイ方式のダンパー機構を提供することを目的とする。   In consideration of the above-described facts, the present invention has an object to provide a one-way damper mechanism that has a short idle time until the damper starts to work and that can obtain a predetermined damper effect regardless of the temperature.

請求項１に記載の発明は、被取付部材に支持され開位置と閉位置との間を回動する開閉部材に取付けられたラックと、前記ラックに噛合可能な第１ギアと、前記第１ギアが噛合可能でダンパーで制御される第２ギアと、前記被取付部材に取付けられ、前記第２ギアが配設されると共に、前記開閉部材が前記開位置へ開放するとき前記第１ギアを前記第２ギアと噛合する方向へスライドさせ、開閉部材が前記閉位置へ閉止するとき第１ギアを第２ギアと噛合解除する方向へスライド可能に保持するベース部材と、を有することを特徴としている。   According to a first aspect of the present invention, there is provided a rack attached to an opening / closing member supported by a member to be attached and rotating between an open position and a closed position, a first gear meshable with the rack, and the first gear. A second gear that is meshable and controlled by a damper, and is attached to the mounted member, the second gear is disposed, and the first gear is opened when the opening and closing member opens to the open position. A base member that slides in a direction to mesh with the second gear, and that holds the first gear slidably in a direction to release meshing with the second gear when the opening and closing member closes to the closed position. Yes.

請求項１に記載の発明では、被取付部材に支持され開位置と閉位置との間を回動する開閉部材にはラックを取付けており、ラックには第１ギアを噛合させるようにしている。この第１ギアには、ダンパーで制御される第２ギアを噛合可能としており、第２ギアと噛合した状態で、第２ギア、第１ギア及びラックを介して、開閉部材にダンパー効果が得られるようにしている。   In the first aspect of the present invention, a rack is attached to the opening / closing member supported by the attached member and rotated between the open position and the closed position, and the first gear is engaged with the rack. . The first gear can be engaged with a second gear controlled by a damper, and a damper effect is obtained for the opening / closing member via the second gear, the first gear, and the rack in a state of being engaged with the second gear. I am trying to do it.

また、被取付部材にはベース部材を取付けており、このベース部材に第２ギアを配設している。ここで、開閉部材を開位置へ開放させるとき、開閉部材と一体に移動するラックによって第１ギアを押圧し、第１ギアと第２ギアとを噛合させる。これにより、開閉部材には、ダンパー効果が付与され、開閉部材はゆっくり開放することとなる。   A base member is attached to the member to be attached, and a second gear is disposed on the base member. Here, when the opening / closing member is opened to the open position, the first gear is pressed by the rack that moves integrally with the opening / closing member, and the first gear and the second gear are engaged. Thereby, a damper effect is given to the opening and closing member, and the opening and closing member is slowly opened.

一方、開閉部材を閉位置へ閉止させるときは、第２ギアから噛合解除する方向へ第１ギアをスライドさせ、ダンパー効果が第１ギアに伝達されないようにしている。これにより、開閉部材を閉止させるとき、開閉部材にはダンパーによる負荷が掛からないようにしている。   On the other hand, when closing the opening / closing member to the closed position, the first gear is slid in the direction to release the mesh from the second gear so that the damper effect is not transmitted to the first gear. Thus, when the opening / closing member is closed, the opening / closing member is prevented from being loaded by the damper.

以上のようにして、このダンパー機構では、確実にワンウェイダンパーとしての効果を得ることができるようにしている。また、開閉部材と一体に移動するラックによって第１ギアを押圧して、第１ギアと第２ギアとを噛合させ、ダンパー効果を得るようにしているため、第１ギアと第２ギアとの離間距離を短くすることで、ダンパーが効き始めるまでの空走時間を短くすることができる。これにより、開閉部材を閉止させるとき、開閉部材を開放させる動作を行なったとしても、瞬時に第１ギアと第２ギアとを噛合させ、ダンパー効果を得ることができる。   As described above, with this damper mechanism, the effect as a one-way damper can be obtained with certainty. In addition, since the first gear is pressed by the rack that moves integrally with the opening / closing member and the first gear and the second gear are engaged with each other to obtain a damper effect, the first gear and the second gear By shortening the separation distance, it is possible to shorten the idle running time until the damper starts to work. Thereby, when closing the opening / closing member, even if an operation for opening the opening / closing member is performed, the first gear and the second gear can be instantaneously engaged to obtain a damper effect.

請求項２に記載の発明は、前記第１ギアの軸部は、前記ベース部材に形成された長孔に沿ってスライドすることを特徴としている。   The invention according to claim 2 is characterized in that the shaft portion of the first gear slides along a long hole formed in the base member.

請求項２に記載の発明では、第１ギアの軸部を、ベース部材に形成した長孔に沿ってスライドさせる。このように、ベース部材に長孔を設け、ダンパー効果を開閉部材へ伝達する第１ギアをスライドさせることで、第２ギアと噛合或いは噛合解除させる。これにより、ダンパーを制御するダンパー部材によるトルク伝達をＯＮ／ＯＦＦし、ダンパー機構をワンウェイ化している。   In the invention according to claim 2, the shaft portion of the first gear is slid along the long hole formed in the base member. In this way, the base member is provided with a long hole, and the first gear that transmits the damper effect to the opening / closing member is slid to engage with or disengage from the second gear. Thereby, torque transmission by the damper member for controlling the damper is turned on / off, and the damper mechanism is made one-way.

請求項３に記載の発明は、第１ギアを第２ギアと噛合解除する方向へ付勢する付勢手段が前記ベース部材に設けられたことを特徴としている。   The invention according to claim 3 is characterized in that the base member is provided with a biasing means for biasing the first gear in the direction of releasing the meshing with the second gear.

請求項３に記載の発明では、第１ギアを第２ギアと噛合解除する方向へ付勢する付勢手段を設けている。すなわち、開閉部材を開放させるとき、ラックによって第１ギアを付勢手段の付勢力に抗して押圧し、第２ギアに噛合させる。   According to a third aspect of the present invention, there is provided urging means for urging the first gear in a direction for releasing the meshing with the second gear. That is, when opening the opening / closing member, the first gear is pressed against the urging force of the urging means by the rack and meshed with the second gear.

請求項４に記載の発明は、前記ラックと前記第１ギアの噛合位置と、前記開閉部材の回動中心位置と、の距離を可変させることを特徴としている。   According to a fourth aspect of the present invention, the distance between the meshing position of the rack and the first gear and the rotation center position of the opening / closing member is variable.

請求項４に記載の発明では、ラックと第１ギアの噛合位置と、開閉部材の回動中心位置と、の距離を可変させることで、ラックと第１ギアの噛合位置において、開閉部材を開放させるために必要な力の大きさを変えることができる。   In the fourth aspect of the invention, the opening / closing member is opened at the meshing position of the rack and the first gear by changing the distance between the meshing position of the rack and the first gear and the rotation center position of the opening / closing member. You can change the amount of force required to

すなわち、ダンパー力（ダンパー部材による制動力）が一定の場合、開閉部材を開放させるために必要な力の大きさが大きいと、該力の大きさが小さい場合と比較してダンパー効果は減少することとなる。   That is, when the damper force (braking force by the damper member) is constant, if the magnitude of the force necessary to open the opening / closing member is large, the damper effect is reduced as compared with the case where the magnitude of the force is small. It will be.

このため、ラックと第１ギアの噛合位置と、開閉部材の回動中心位置と、の距離を変え、開閉部材の開放開始（閉位置）側では、第１ギアとラックの噛合位置と、開閉部材の回転中心位置と、の距離を短くして、ラックと第１ギアの噛合位置において開閉部材を開放させるために必要な力の大きさを大きくし、開閉部材の開放終了（開位置）側では、第１ギアとラックの噛合位置と、開閉部材の回転中心位置と、の距離を長くして該力の大きさを小さくする。   Therefore, the distance between the meshing position of the rack and the first gear and the rotation center position of the opening / closing member is changed, and on the opening start (closed position) side of the opening / closing member, the meshing position of the first gear and the rack and the opening / closing Shorten the distance from the rotation center position of the member, increase the amount of force required to open the opening / closing member at the meshing position of the rack and the first gear, and open / close the opening / closing member (open position) side Then, the distance between the meshing position of the first gear and the rack and the rotation center position of the opening / closing member is increased to reduce the magnitude of the force.

これにより、開閉部材の閉位置側では、開位置側と比較して、ダンパー力は小さくなる。このため、低温領域でも開閉部材を確実に開放させることができることとなる。   Accordingly, the damper force is smaller on the closed position side of the opening / closing member than on the open position side. For this reason, the opening / closing member can be reliably opened even in a low temperature region.

請求項５に記載の発明は、前記ラックが直線状であると共に、前記ベース部材が前記側壁に揺動可能に取付けられたことを特徴としている。   The invention according to claim 5 is characterized in that the rack is linear and the base member is swingably attached to the side wall.

請求項５に記載の発明では、開閉部材と一体に移動するラックを直線状にすると共に、ラックと噛合する第１ギアが取付けられたベース部材を被取付部材に揺動可能に取付けることで、第１ギアとラックが噛合位置と、開閉部材の回転中心位置と、の距離を変えるようにしている。   In the invention according to claim 5, by making the rack that moves integrally with the opening and closing member linear, and attaching the base member to which the first gear meshing with the rack is attached to the attached member in a swingable manner, The distance between the meshing position of the first gear and the rack and the rotation center position of the opening / closing member is changed.

具体的には、開閉部材の閉位置側では、ラックと第１ギアの噛合位置と、開閉部材の回動中心位置と、の距離を短くし、開閉部材の開位置側では、ラックと第１ギアの噛合位置と、開閉部材の回動中心位置と、の距離を長くしている。   Specifically, on the closed position side of the opening / closing member, the distance between the meshing position of the rack and the first gear and the rotation center position of the opening / closing member is shortened, and on the opening position side of the opening / closing member, The distance between the meshing position of the gear and the rotation center position of the opening / closing member is increased.

本発明は上記構成としたので、請求項１に記載の発明では、確実にワンウェイダンパーとしての効果を得ることができるようにしている。また、開閉部材と一体に移動するラックによって第１ギアを押圧して、第１ギアと第２ギアとを噛合させ、ダンパー効果を得るようにしているため、第１ギアと第２ギアとの離間距離を短くすることで、ダンパーが効き始めるまでの空走時間を短くすることができる。これにより、開閉部材を閉止させるとき、開閉部材を開放させる動作を行なったとしても、瞬時に第１ギアと第２ギアとを噛合させ、ダンパー効果を得ることができる。   Since the present invention is configured as described above, the invention according to claim 1 can reliably obtain an effect as a one-way damper. In addition, since the first gear is pressed by the rack that moves integrally with the opening / closing member and the first gear and the second gear are engaged with each other to obtain a damper effect, the first gear and the second gear By shortening the separation distance, it is possible to shorten the idle running time until the damper starts to work. Thereby, when closing the opening / closing member, even if an operation for opening the opening / closing member is performed, the first gear and the second gear can be instantaneously engaged to obtain a damper effect.

請求項２に記載の発明では、ダンパーを制御するダンパー部材によるトルク伝達をＯＮ／ＯＦＦし、ダンパー機構をワンウェイ化している。   According to the second aspect of the present invention, the torque transmission by the damper member for controlling the damper is turned on / off to make the damper mechanism one-way.

請求項３に記載の発明では、開閉部材を開放させるとき、ラックによって第１ギアを付勢手段の付勢力に抗して押圧し、第２ギアに噛合させる。   According to the third aspect of the present invention, when the opening / closing member is opened, the first gear is pressed against the urging force of the urging means by the rack and meshed with the second gear.

請求項４及び請求項５に記載の発明では、ラックと第１ギアの噛合位置と、開閉部材の回動中心位置と、の距離を変え、開閉部材の閉位置側では、第１ギアとラックの噛合位置と、開閉部材の回転中心位置と、の距離を短くして、ラックと第１ギアの噛合位置において開閉部材を開放させるために必要な力の大きさを大きくし、開閉部材の開位置側では、第１ギアとラックの噛合位置と、開閉部材の回転中心位置と、の距離を長くして、該力の大きさを小さくする。これにより、開閉部材の閉位置側では、開位置側と比較して、ダンパー効果を小さくすることができる。このため、低温領域でも開閉部材を確実に開放させることができることとなる。   According to the fourth and fifth aspects of the present invention, the distance between the meshing position of the rack and the first gear and the rotation center position of the opening / closing member is changed. The opening position of the opening / closing member is increased by reducing the distance between the meshing position of the opening / closing member and the rotation center position of the opening / closing member, and increasing the magnitude of the force required to open the opening / closing member at the meshing position of the rack and the first gear. On the position side, the distance between the meshing position of the first gear and the rack and the rotation center position of the opening / closing member is increased to reduce the magnitude of the force. Accordingly, the damper effect can be reduced on the closed position side of the opening / closing member as compared with the open position side. For this reason, the opening / closing member can be reliably opened even in a low temperature region.

以下に、本発明の実施の形態に係るダンパー機構について説明する。   The damper mechanism according to the embodiment of the present invention will be described below.

図１に示すように、車両のインストルメントパネル１０（被取付部材）の助手席側にはグローブボックス１２（いわゆる小物入れのこと）が設けられている。このグローブボックス１２の開閉部材２０は、略箱状を成し、開閉部材２０には、図２（Ａ）、（Ｂ）に示すように、ダンパー機構１４が設けられており、ダンパー機構１４には、互いに噛合可能なラック１６とギア１８が備えられている。   As shown in FIG. 1, a glove box 12 (so-called accessory case) is provided on the passenger seat side of an instrument panel 10 (attached member) of a vehicle. The opening / closing member 20 of the glove box 12 has a substantially box shape, and the opening / closing member 20 is provided with a damper mechanism 14 as shown in FIGS. Is provided with a rack 16 and a gear 18 which can be engaged with each other.

ラック１６は、直線状に形成されており、開閉部材２０の側壁２０Ａに取付けられ、開閉部材２０と一体に移動する。開閉部材２０は軸部２２を中心に回動可能となっており、ラック１６もまた軸部２２を中心に回動する。   The rack 16 is formed in a straight line, is attached to the side wall 20 </ b> A of the opening / closing member 20, and moves integrally with the opening / closing member 20. The opening / closing member 20 is rotatable about the shaft portion 22, and the rack 16 is also rotated about the shaft portion 22.

一方、ギア１８は、図３及び図４（Ａ）、（Ｂ）（なお、図４（Ａ）、（Ｂ）はそれぞれ図２（Ａ）、（Ｂ）の部分拡大図である）に示すように、略箱状のベース部材２４の一端側に取付け可能となっている。ベース部材２４の一端側には、長孔２６が設けられており、この長孔２６にギア１８の軸部３０が挿通し、長孔２６に沿ってギア１８の軸部３０がスライドするようになっている。   On the other hand, the gear 18 is shown in FIGS. 3 and 4A and 4B (note that FIGS. 4A and 4B are partially enlarged views of FIGS. 2A and 2B, respectively). Thus, it can be attached to one end side of the substantially box-shaped base member 24. A long hole 26 is provided on one end side of the base member 24, and the shaft portion 30 of the gear 18 is inserted into the long hole 26 so that the shaft portion 30 of the gear 18 slides along the long hole 26. It has become.

具体的には、ギア１８の軸部３０の先端側には小径部３２が形成されており、先端部には円錐部３４が形成されている。小径部３２及び円錐部３４の周壁には、軸部３０の軸方向に沿って連続する切欠き部３５が形成されており、軸部３０の先端側を縮径可能としている。   Specifically, a small diameter portion 32 is formed on the distal end side of the shaft portion 30 of the gear 18, and a conical portion 34 is formed on the distal end portion. The peripheral wall of the small diameter portion 32 and the conical portion 34 is formed with a notch portion 35 that is continuous along the axial direction of the shaft portion 30, so that the diameter of the tip side of the shaft portion 30 can be reduced.

軸部３０を長孔２６に挿通させるとき小径部３２及び円錐部３４を縮径させ、小径部３２及び円錐部３４とで構成される当接面３４Ａが、長孔２６の内縁部から立設しベース部材２４の周壁２４Ａが連設された係止壁３６の先端部を通過すると、円錐部３４を復元させ、当接面３４Ａを係止壁３６の先端面に当接させてギア１８をベース部材２４にスライド可能に係止させる。   When the shaft portion 30 is inserted through the long hole 26, the small diameter portion 32 and the conical portion 34 are reduced in diameter, and a contact surface 34 </ b> A constituted by the small diameter portion 32 and the conical portion 34 stands from the inner edge of the long hole 26 When the peripheral wall 24A of the base member 24 passes through the distal end portion of the locking wall 36 provided continuously, the conical portion 34 is restored, the contact surface 34A is brought into contact with the distal end surface of the locking wall 36, and the gear 18 is moved. The base member 24 is slidably locked.

ところで、図２（Ａ）に示すように、ベース部材２４の他端部は、開閉部材２０を閉止させた状態で、ギア１８がラック１６の一端部と噛合可能な位置となるようにインストルメントパネル１０に回動可能に支持されている。また、ベース部材２４の他端側には、図示しないトーションバネが配設されており、自由端であるベース部材２４の一端側をラック１６側へ付勢している。   2A, the other end of the base member 24 is positioned so that the gear 18 can be engaged with one end of the rack 16 with the opening / closing member 20 closed. The panel 10 is rotatably supported. Further, a torsion spring (not shown) is disposed on the other end side of the base member 24, and biases one end side of the base member 24 which is a free end toward the rack 16 side.

そして、開閉部材２０の開放に伴って、ラック１６及びギア１８を介してベース部材２４は揺動すると共に、ギア１８が噛合するラック１６の位置がズレ、図２（Ｂ）に示すように、開閉部材２０の開放終了位置（開位置）では、ギア１８はラック１６の他端部と噛合するように配置される。   As the opening / closing member 20 is opened, the base member 24 swings via the rack 16 and the gear 18, and the position of the rack 16 with which the gear 18 meshes is displaced, as shown in FIG. At the opening end position (open position) of the opening / closing member 20, the gear 18 is disposed so as to mesh with the other end portion of the rack 16.

また、図３及び図４（Ａ）、（Ｂ）に示すように、ベース部材２４にはギア１８と噛合可能なギア３８が配設されており、ギア１８が長孔２６に沿ってスライドすることで、ギア３８と噛合可能な位置或いは噛合解除される位置となる。   As shown in FIGS. 3 and 4A and 4B, the base member 24 is provided with a gear 38 that can mesh with the gear 18, and the gear 18 slides along the long hole 26. Thus, the position can be meshed with the gear 38 or the mesh can be released.

ここで、ギア１８がギア３８と噛合する位置では、開閉部材２０（図２（Ａ）、（Ｂ）参照）が開放するときに、ラック１６がギア１８を押圧する方向にギア３８が配置され、ギア１８とギア３８とが確実に噛合されるようになっている。   Here, at a position where the gear 18 meshes with the gear 38, the gear 38 is arranged in a direction in which the rack 16 presses the gear 18 when the opening / closing member 20 (see FIGS. 2A and 2B) is opened. The gear 18 and the gear 38 are surely engaged with each other.

ギア３８の軸部３７の外周面には、軸部３７の軸方向に沿って係合部４０が弾性変形可能に設けられている。軸部３７の先端側には、小径部４２が形成されており、軸部３７の先端部には、先端部へ行くに従って互いに離間する方向へ広がる一対の係止爪４４が設けられ、この係止爪４４は弾性変形可能となっている。   An engaging portion 40 is provided on the outer peripheral surface of the shaft portion 37 of the gear 38 so as to be elastically deformable along the axial direction of the shaft portion 37. A small-diameter portion 42 is formed on the distal end side of the shaft portion 37, and a pair of locking claws 44 are provided at the distal end portion of the shaft portion 37 so as to be separated from each other toward the distal end portion. The pawl 44 is elastically deformable.

軸部３７には内部にオイルが充填された円筒状のダンパー４６が連結可能となっている。ダンパー４６の軸芯部へギア３８の軸部３７を挿通させるとき、係止爪４４を縮径させ、軸芯部へ挿通させる。ダンパー４６の軸芯部に設けられた被係合部（図示省略）に係合部４０を係合させ、軸部３０とダンパー４６を連結させる。   A cylindrical damper 46 filled with oil can be connected to the shaft portion 37. When the shaft portion 37 of the gear 38 is inserted into the shaft core portion of the damper 46, the diameter of the locking claw 44 is reduced and inserted into the shaft core portion. The engaging portion 40 is engaged with an engaged portion (not shown) provided in the shaft core portion of the damper 46 to connect the shaft portion 30 and the damper 46.

これにより、ギア３８の回転によって、軸部３７を介してダンパー４６内に配置された翼４８には、粘性抵抗等が掛かり、ギア３８には、ダンパー力（ダンパー４６による制動力）が付与されることとなる。   As a result, due to the rotation of the gear 38, viscous resistance or the like is applied to the blades 48 arranged in the damper 46 via the shaft portion 37, and a damper force (braking force by the damper 46) is applied to the gear 38. The Rukoto.

また、ベース部材２４にはダンパー４６が収容可能な収容凹部５１がベース部材２４の底面から内部側へ向かって凹設されており、収容凹部５１の底面の裏面と係止壁３６の先端面とベース部材２４の周壁２４Ａの先端面とが面一となっている。また、収容凹部５１の中心部には、軸部３７が挿通可能な丸孔５０が形成され、丸孔５０の周縁部からは収容凹部５１と反対側に係止壁５２が立設している。   The base member 24 is provided with a receiving recess 51 in which the damper 46 can be received from the bottom surface of the base member 24 toward the inside. The back surface of the bottom surface of the receiving recess 51 and the front end surface of the locking wall 36 are provided. The front end surface of the peripheral wall 24A of the base member 24 is flush with the surface. In addition, a round hole 50 into which the shaft portion 37 can be inserted is formed at the center of the accommodation recess 51, and a locking wall 52 is erected on the opposite side of the accommodation recess 51 from the peripheral edge of the round hole 50. .

ダンパー４６を収容凹部５１内へ収容すると共に、ダンパー４６の軸芯部を挿通した係止爪４４を縮径した状態で丸孔５０へ挿通し、係止壁５２が先端部を通過すると係止爪４４を復元させ、係止爪４４の先端部を係止壁３６の先端面に当接させて、ギア３８を収容凹部５１から露出させた状態でベース部材２４に係止させる。   The damper 46 is accommodated in the accommodating recess 51, and the locking claw 44 inserted through the shaft core portion of the damper 46 is inserted into the round hole 50 in a reduced diameter state, and is locked when the locking wall 52 passes through the tip. The claw 44 is restored, the front end of the locking claw 44 is brought into contact with the front end surface of the locking wall 36, and the gear 38 is locked to the base member 24 while being exposed from the housing recess 51.

さらに、ベース部材２４にはトーションバネ５４の一端部が固定されており、トーションバネ５４の他端部は、ギア１８に当接し、ギア１８をギア３８から離間させる方向へ付勢している。このため、開閉部材２０が開放するときに、ラック１６によってギア１８はトーションバネ５４の付勢力の抗する方向へ押圧されてギア３８と噛合する。   Further, one end portion of a torsion spring 54 is fixed to the base member 24, and the other end portion of the torsion spring 54 abuts on the gear 18 and urges the gear 18 in a direction away from the gear 38. For this reason, when the opening / closing member 20 is opened, the gear 18 is pressed by the rack 16 in a direction against the urging force of the torsion spring 54 and meshes with the gear 38.

次に、本発明の実施の形態に係るダンパー機構を用いたグローブボックスの開閉部材２０の開放動作について説明する。   Next, the opening operation of the opening / closing member 20 of the glove box using the damper mechanism according to the embodiment of the present invention will be described.

図２（Ａ）及び図４（Ａ）に示すように、開閉部材２０が閉止された状態では、ギア１８がラック１６の一端部と噛合すると共に、トーションバネ５４によってギア１８はギア３８から離間する方向へ付勢され、ギア３８と噛合解除している。   As shown in FIGS. 2A and 4A, when the opening / closing member 20 is closed, the gear 18 meshes with one end of the rack 16 and the gear 18 is separated from the gear 38 by the torsion spring 54. The gear 38 is released from being engaged.

この状態から開閉部材２０を開放させると、図２（Ｂ）及び図４（Ｂ）に示すように、開閉部材２０と一体に軸部２２を中心にラック１６が回動し、ラック１６によって、ギア１８がトーションバネ５４の付勢力に抗する方向へ押圧され、ベース部材２４の長孔２６内をスライドする。   When the opening / closing member 20 is opened from this state, as shown in FIGS. 2B and 4B, the rack 16 rotates around the shaft portion 22 integrally with the opening / closing member 20. The gear 18 is pressed in a direction against the urging force of the torsion spring 54, and slides in the long hole 26 of the base member 24.

これにより、ギア１８がギア３８と噛合し、ダンパー４６によるダンパー効果がギア３８を介してギア１８に伝達され、ラック１６を介して開閉部材２０にはダンパー効果が伝達され、開閉部材２０がゆっくり開放されることとなる。   As a result, the gear 18 meshes with the gear 38, the damper effect by the damper 46 is transmitted to the gear 18 via the gear 38, the damper effect is transmitted to the opening / closing member 20 via the rack 16, and the opening / closing member 20 slowly moves. It will be released.

このとき、開閉部材２０が開放するに従って、ラック１６とギア１８との噛合位置がラック１６の一端部からラック１６の他端部側へズレると共に、ベース部材２４の一端部が開閉部材２０の回転中心位置Ｏから離間する方向へ揺動する。   At this time, as the opening / closing member 20 opens, the meshing position of the rack 16 and the gear 18 shifts from one end of the rack 16 to the other end of the rack 16, and one end of the base member 24 rotates the opening / closing member 20. It swings in a direction away from the center position O.

次に、本発明の実施の形態に係るダンパー機構を用いたグローブボックスの開閉部材２０の閉止動作について説明する。   Next, the closing operation of the opening / closing member 20 of the glove box using the damper mechanism according to the embodiment of the present invention will be described.

開閉部材２０を閉止させると、ラック１６はギア１８から離間する方向へ向かって移動するため、ギア１８をギア３８へ向かって押圧する方向へ力は働かないことになる。このため、ギア１８は、トーションバネ５４の付勢力によってギア３８から離間する方向へスライドする（図４（Ａ）参照）。   When the opening / closing member 20 is closed, the rack 16 moves in a direction away from the gear 18, so that no force acts in the direction of pressing the gear 18 toward the gear 38. For this reason, the gear 18 slides in a direction away from the gear 38 by the urging force of the torsion spring 54 (see FIG. 4A).

従って、ギア１８にはダンパー４６によるダンパー効果が伝達されないことになり、開閉部材２０を閉止させるときには、ダンパー４６による負荷は掛からない。   Therefore, the damper effect by the damper 46 is not transmitted to the gear 18, and no load is applied by the damper 46 when the opening / closing member 20 is closed.

次に、本発明の実施に係るダンパー機構の作用について説明する。   Next, the operation of the damper mechanism according to the embodiment of the present invention will be described.

図２（Ｂ）及び図４（Ｂ）に示すように、開閉部材２０にラック１６を取付け、開閉部材２０と一体に回動させるようにすると共に、ラック１６にギア１８を噛合させるようにしている。このギア１８には、ダンパー４６と連結されたギア３８を噛合可能とし、ギア１８とギア３８とが噛合した状態で、ギア３８、ギア１８及びラック１６を介して開閉部材２０にはダンパー効果が得られるようにしている。   As shown in FIGS. 2B and 4B, the rack 16 is attached to the opening / closing member 20 so as to rotate integrally with the opening / closing member 20, and the gear 18 is engaged with the rack 16. Yes. The gear 18 can be engaged with a gear 38 connected to a damper 46. When the gear 18 and the gear 38 are engaged, the opening / closing member 20 has a damper effect via the gear 38, the gear 18, and the rack 16. I try to get it.

また、インストルメントパネル１０には、ベース部材２４を揺動可能に取付け、ベース部材２４にギア１８、３８を配設し、ギア１８をスライド可能に保持して、ギア３８と噛合或いは噛合解除可能としている。   Further, a base member 24 is swingably attached to the instrument panel 10, and gears 18 and 38 are disposed on the base member 24, and the gear 18 can be slidably held to engage with or release from the gear 38. It is said.

このため、開閉部材２０を開放させるとき、開閉部材２０と一体に移動するラック１６によってギア１８を押圧し、ギア１８とギア３８とを噛合させることで、開閉部材２０には、ダンパー効果が付与され、開閉部材２０をゆっくり開放させることができる。   Therefore, when the opening / closing member 20 is opened, the gear 18 is pressed by the rack 16 that moves integrally with the opening / closing member 20, and the gear 18 and the gear 38 are engaged with each other, so that the opening / closing member 20 has a damper effect. Thus, the opening / closing member 20 can be opened slowly.

一方、開閉部材２０を閉止させるとき、図２（Ａ）及び図４（Ａ）に示すように、ギア３８から噛合解除する方向へギア１８をスライドさせ、ダンパー効果がギア１８に伝達されないようにしている。これにより、開閉部材２０を閉止させるとき、開閉部材２０にはダンパー４６による負荷が掛からないようにしている。   On the other hand, when the opening / closing member 20 is closed, as shown in FIGS. 2A and 4A, the gear 18 is slid in the direction of releasing the mesh from the gear 38 so that the damper effect is not transmitted to the gear 18. ing. Thus, when the opening / closing member 20 is closed, the opening / closing member 20 is prevented from being loaded by the damper 46.

このように、ベース部材２４に長孔２６を設け、ダンパー効果を開閉部材２０へ伝達するギア１８をスライドさせ、ギア３８と噛合或いは噛合解除させることで、ダンパー４６によるトルク伝達をＯＮ／ＯＦＦし、ダンパー機構１４をワンウェイ化している。   In this way, the base member 24 is provided with the long hole 26, and the gear 18 that transmits the damper effect to the opening / closing member 20 is slid to engage with or release from the gear 38, thereby turning on / off the torque transmission by the damper 46. The damper mechanism 14 is made one-way.

また、開閉部材２０と一体に移動するラック１６によってギア１８を押圧して、ギア１８とギア３８とを噛合させ、ダンパー効果を得るようにしているため、ギア１８とギア３８との離間距離を短くすることで、ダンパーが効き始めるまでの空走時間を短くすることができる。これにより、開閉部材２０を閉止させるとき、開閉部材２０を開放させる動作を行なったとしても、瞬時にギア１８とギア３８とを噛合させ、ダンパー効果を得ることができる。   Further, the gear 18 is pressed by the rack 16 that moves integrally with the opening / closing member 20, and the gear 18 and the gear 38 are engaged with each other to obtain a damper effect. Therefore, the separation distance between the gear 18 and the gear 38 is increased. By shortening, it is possible to shorten the idling time until the damper starts to work. Thereby, when closing the opening / closing member 20, even if the opening / closing member 20 is opened, the gear 18 and the gear 38 can be instantaneously engaged with each other to obtain a damper effect.

ここで、図２（Ａ）、（Ｂ）に示すように、ラック１６を直線状にすると共に、ベース部材２４をインストルメントパネル１０の側壁に揺動可能に取付けることで、ラック１６とギア１８の噛合位置Ｐと、開閉部材２０の回動中心位置Ｏ、との距離を可変させることができる。これにより、ラック１６とギア１８の噛合位置Ｐにおいて開閉部材２０を開放させるために必要な力の大きさを変えることができる。   Here, as shown in FIGS. 2A and 2B, the rack 16 is linear, and the base member 24 is swingably attached to the side wall of the instrument panel 10, whereby the rack 16 and the gear 18 are mounted. The distance between the meshing position P and the rotation center position O of the opening / closing member 20 can be varied. Thereby, the magnitude of the force required to open the opening / closing member 20 at the meshing position P between the rack 16 and the gear 18 can be changed.

すなわち、ダンパー力（ダンパー部材による制動力）が一定の場合、開閉部材２０を開放させるために必要な力の大きさが大きいと、該力の大きさが小さい場合と比較してダンパー効果は減少することとなる。   That is, when the damper force (braking force by the damper member) is constant, if the magnitude of the force required to open the opening / closing member 20 is large, the damper effect is reduced compared to the case where the magnitude of the force is small. Will be.

このため、ラック１６とギア１８の噛合位置Ｐと、開閉部材２０の回動中心位置Ｏと、の距離を変え、開閉部材２０の開放開始（閉位置）側では、ギア１８とラック１６の噛合位置Ｐと、開閉部材２０の回動中心位置Ｏと、の距離Ｌ1を短くしてラック１６とギア１８の噛合位置Ｐにおいて開閉部材２０を開放させるために必要な力の大きさを大きくし、開閉部材２０の開放終了（開位置）側では、ギア１８とラック１６の噛合位置Ｐと、開閉部材２０の回動中心位置Ｏと、の距離Ｌ2を長くして該力の大きさを小さくする。 Therefore, the distance between the meshing position P of the rack 16 and the gear 18 and the rotation center position O of the opening / closing member 20 is changed, and the gear 18 and the rack 16 are meshed on the opening start (closed position) side of the opening / closing member 20. The distance L 1 between the position P and the rotation center position O of the opening / closing member 20 is shortened to increase the amount of force required to open the opening / closing member 20 at the meshing position P between the rack 16 and the gear 18. , in the open ends (open position) of the closing member 20, and the meshing position P of the gear 18 and the rack 16, and the rotational center position O of the opening and closing member 20, the distance L 2 of the long to the magnitude of the force of Make it smaller.

これにより、開閉部材２０の閉位置側では、開位置側と比較して、ダンパー効果は小さくなる。このため、低温領域でも開閉部材２０を確実に開放させることができることとなる。   Thereby, the damper effect is smaller on the closed position side of the opening / closing member 20 than on the open position side. For this reason, the opening / closing member 20 can be reliably opened even in the low temperature region.

なお、本形態では、ラック１６を直線状としたが、開閉部材２０の回動中心位置Ｏを中心とする円弧状としても良い。但し、この場合、ワンウェイダンパーとしての効果は得られるが、開閉部材２０の閉位置側と開位置側とではダンパー効果が略同一である。   In this embodiment, the rack 16 is linear. However, the rack 16 may be arcuate around the rotation center position O of the opening / closing member 20. However, in this case, the effect as a one-way damper is obtained, but the damper effect is substantially the same between the closed position side and the open position side of the opening / closing member 20.

また、ラックを、開閉部材２０の開放に伴って、開閉部材２０の回動中心位置Ｏからの距離が長くなるようにした円弧としても良い。これにより、開閉部材２０の閉位置側と開位置側とでダンパー効果を変えることができる。   Further, the rack may be an arc whose distance from the rotation center position O of the opening / closing member 20 becomes longer as the opening / closing member 20 is opened. Thereby, the damper effect can be changed between the closed position side and the open position side of the opening / closing member 20.

さらに、本形態では、ラック１６を固定し、ベース部材２４を揺動させるようにしたが、ギア１８とラック１６の噛合位置Ｐと、開閉部材２０の回動中心位置Ｏと、の距離を変えることができれば良いため、これに限るものではなく、ラック１６を揺動させるようにしても良い。   Furthermore, in this embodiment, the rack 16 is fixed and the base member 24 is swung, but the distance between the meshing position P of the gear 18 and the rack 16 and the rotation center position O of the opening / closing member 20 is changed. However, the present invention is not limited to this, and the rack 16 may be swung.

また、開閉部材２０を略箱状に形成させたが、開閉部材２０は単に板状の扉であっても良く、この場合、ラック１６は扉に対して直交する方向へ張り出すようにして取付けても良い。   Although the opening / closing member 20 is formed in a substantially box shape, the opening / closing member 20 may be simply a plate-like door. In this case, the rack 16 is attached so as to protrude in a direction perpendicular to the door. May be.
