Description

【0001】
【発明の属する技術分野】
本発明は、車両の開口部に開閉可能に設けられたドアの開度を規制するドア開度ロック機構に関する。
【0002】
【従来の技術】
車両の開口部と、これに開閉可能に設けられたドアとの間には、ドアが自重で勝手に開閉しないように、所謂ドアチェック装置やそれに類似した機構が設けられている。例えば、特開平7−257186号公報では、長手方向に沿って複数の係合部を列設された係合手段をボディー側に枢支し、係合部と係脱可能な係合爪をドアの開閉時の移動方向に回動自在に設け、この係合爪の回動方向に弾機手段を配置して同係合爪を係合部と係合する位置に保持し、ドアの開閉動作に伴い移動する係合手段に抵抗を与えてドアの位置を規制するものが提案されている。
【0003】
【発明が解決しようとする課題】
上述した従来の技術では、係合爪が弾機手段で係合部と係合する位置に保持されているので、ドアの自重による勝手な開閉動作を防止することはできるが、ドアの閉方向への移動時にも、係合爪は弾機手段の弾性力を受け、かつ係合部とも係合した状態にある。このため、係合爪を選択的に係合部に係脱することができず、ドアを閉じる際の抵抗が大きく、ドアをスムーズに戻することができない。また、係合爪が弾機手段で係合部に付勢されているので、弾機手段の経時変化による付勢力の変化が伴い、長期に渡って安定したドアの位置決めが難しい。さらに、弾機手段を変形させるだけの力が加わると、ドアの開閉方向のいずれの方向にも係合爪が回動して係合部を乗り越えるので、ドアの停止性に問題が残る。
本発明は、長期に渡って確実にドアを任意の開度で停止でき、ドア閉動作をスムーズに行えるドア開度ロック機構を提供することを目的とする。
【0004】
【課題を解決するための手段】
上記目的を達成するため、本発明の請求項1では、車両の開口部または、この開口部に開閉可能に設られたドアのいずれか一方に、長手方向に沿って複数の係合部を列設された係合手段を設け、係合部との係合時に、ドアの閉方向への移動を許しドアの開方向への移動を妨げる係合爪を係合部と係脱可能に設け、係合部と係合する係合位置と、係合部と係合しない離脱位置とに係合爪を制御手段で選択的に位置させるように構成しているため、係合爪を選択的に係合位置に位置させることができ、係合位置においてはドアの開方向への移動が規制されドアの閉方向への移動は許される。このため、ドアは所望の開度でロックされると共に、閉方向への移動に際しては抵抗少なく移動できる。
【0005】
ドアの開度0°(全閉時)から係合部と係合爪が係合してしまうと、ドアを開けることができなくなるので、両者の係合は、少なくとも車両への乗降者が制御手段を操作できる程度の開度を確保する。このため、制御手段を操作するための操作部は、ドアの内側や開口部の周縁に配置されたラッチ寄りに配置するのが好ましい。
【0006】
制御手段としては、操作部と係合爪とをリンク機構を介して連結して手動式としたり、リンク機構中に同機構を動作させる電磁アクチュエータを設け、この電磁アクチュエータを電気的なコントローラに接続し、このコントローラにオン/オフスイッチを接続して電動式としてもよい。
【0007】
本発明は、ドアの回動端側に配置される周知のドアチェック装置と併設したり、単独で設けても構わない。ドアチェック装置と一緒に設ける場合、ドアチェック装置が機能する開度よりも少ない開度で機能するように設けるとよい。このため、ドア開度ロック機構の開度は、本発明が採用されるドアの全開閉範囲であっても良く、また、ドアチェック装置を備えたドアにおいては、この装置によるドアの開閉規制を受ける開度よりも小さい開閉範囲が含まれる。ドアチェック装置は、一般にドアが少し開いた程度では機能しないものが多いため、車両への乗降時における隣接する車両や縁石や壁等の隣接物に対するドアの接触を確実に防止することを考慮すると、ドア開度の少ない時からドア開度ロック機構を機能するように構成するのが望ましい。
【0008】
【発明の実施の形態】
以下、図面を用いて本発明の実施の形態を説明する。
図1に示すドア開度ロック機構は、図2に示す車両1の側面に形成された開口部となる乗降口2に開閉可能に設けられたドア3の開度を規制するものである。本形態では、乗降口2とドア3の回動端3aとの間に周知の図示しないドアチェック装置が装着されており、ドア開度ロック機構との併設を図られている。
【0009】
ドア開度ロック機構は、このドアチェック装置が機能するドア3の開度よりも少ない開度で機能するように構成されている。ドア開度ロック機構は、図1、図3に示すように、ドア3にピン4で枢支され、係合部となる突起6を備えた係合手段となる移動レバー5と、突起6と係脱可能に設けられた係合爪7と、この係合爪7を、図3に示す突起6と係合する係合位置と、図1に示す突起6と係合しない離脱位置とに選択的に位置させる制御手段8とを備えている。
【0010】
移動レバー5は、ドア3の移動方向に延出していて、その長手方向に沿って突起6が複数列設されている。突起6は直角三角形状を成し、その斜面6aが矢印bで示すドア3の閉方向(以下「閉方向b」と記す)に位置し、垂直面6bが矢印aで示すドア3の開方向(以下「開方向a」と記す)側に位置するように配置されている。移動レバー5は、乗降口2(車両1)の一部に形成された図示しない開口内に挿入されていて、閉方向b側に位置する移動レバー5の他端に、図示しない開口に当接するストッパ9が形成されている。移動レバー5の一側面には、レバーの長手方向に延出するガイド部10が紙面から突出する向きに形成されている。
【0011】
ガイド部10は、乗降口2の周縁に固定された案内部材11によって支持されている。案内部材11には、図4に示すように、ガイド部10を上下から覆う断面コの字状の案内部11Aが形成されている。案内部11Aの内部には、複数のボール12が移動レバー5の長手方向に向かって並設されている。このボール12は、転動自在に保持されていて、ガイド部10の上面10aと下面10bに摺接しており、ガイド部10を摺動自在に支持して移動レバー5の移動をガイドするようになっている。案内部材11には、固定軸13,14と、バネかけ部15が形成されている。これらは、案内部材11に一体的に設けられているため、ロック状態時に外力が作用しても、移動レバー5と係合爪7が相対的に変位するのを容易に防止でき、装置の信頼性を向上することができる。
【0012】
係合爪7は、図1,図3に示すように、固定軸13にその基端を回動自在に支持されている。係合爪7の先端下部には、突起6に類似した形状の凹部7aが形成されていて、突起6との係合時に、ドア3の閉方向bへの移動を許し、ドア3の開方向aへの移動を妨げるようになっている。係合爪7の先端側には、バネかけ部15に一端を係止された引っ張りバネ16の他端が係止されていて、係合爪7に図1に示す退避位置への回動習性を与えている。
【0013】
制御手段8は、操作部となる操作レバー17、第1レバー18、第2レバー19、第3レバー20、コネクチングロッド21、トルクスプリング22を備えている。操作レバー17は、一端を第1レバー18とピン結合され、他端に操作ノブ23を装着されており、乗降口2に設けられる図示しないラッチの近傍の内装24から車室内に突出して配置されている。
【0014】
第1レバー18と第2レバー19のそれぞれの基端は、図示しない車両の基部に回転自在に支持された支軸25に固定されている。第3レバー20は、固定軸14に回動自在に支持されていて、その先端20aを係合爪7の上部7bに当接させている。コネクチングロッド21は、その両端がそれぞれ第2レバー19と第3レバー20にピン26,27で結合されていて、第2レバー19と第3レバー20を連結している。トルクスプリング22は、引っ張りバネから成り、その一端をピン26に係止し、他端を支軸25の上方に配置されたバネかけピン28に係止させており、操作レバー17を図1に示す非ロック位置と図3に示すロック位置とにそれぞれ保持するようになっている。これら各レバー並びにコネクチングロッドによってリンク機構が構成されている。
【0015】
バネかけピン28は、好ましくは第2レバー19の揺動範囲角度の2等分線上で、かつ支軸25の上方延長線上に設ける。このように設けると、トルクスプリング22は、第2レバー19が揺動し、上記2等分線上に位置した時に、最大張力を発生することになるので、第2レバー19がロック位置または解除位置の何れかの位置に保持されるように、トルクスプリング22の張力が作用することになる。
【0016】
このような構成のドア開度ロック機構の動作を説明する。
(降車時の動作)
乗員が隣接する車両、壁や縁石、カードレール等に代表される隣接物に接触しない程度の範囲でドア3を開方向aに開き、操作ノブ23を図1に示す非ロック位置から図3に示すロック位置へと押し込む。これにより、第1レバー18と第2レバー19とが支軸25を中心に反時計回りに一定の角度を保ったまま回動して第3レバー20が固定軸14を中心に時計回り方向に回動する。すると、係合爪7の上面7bが先端20aで下方に押されて係合爪7が引っ張りバネ16の付勢力に抗して、図1に示す離間位置から図3に示す係合位置へと移動して、凹部7aが突起6に係合する。このため、ドア3を開方向aに移動しようとすると、突起6の垂直面6bと凹部7aの平面7cとが当接するので、移動レバー5の移動が規制されてドア3が開方向にのみロック状態となる。
【0017】
このように、所望するドア3の開度と成ったときに、操作ノブ23を押し込むとドア3が所望の開度でロックされるので、ドア3と、開方向aに位置する隣接物との接触を確実に避けることができ、隣接物やドア3の傷並びに破損を防止できる。
【0018】
係合爪7と突起6との係合を解除するには、図5に示すように、ロック状態にあるドア3を閉方向bに移動する。すると、突起6の傾斜面6aによって係合爪7の先端が持ち上げられ、係合爪7が固定軸13を中心に反時計回りに回動し、引っ張りバネ16の付勢力と相まって係合爪7が離間位置に保持される。また、係合爪7の動作により第3レバー20が固定軸14を中心に反時計回りに回動し、コネクチングロッド21を介して第2レバー2が左方に引かれる。このため、第1レバー18と第2レバー19が支軸25を中心に時計回りに一定の角度を保持したまま回動し、操作レバー17が押し上げられて操作ノブ23が非ロック位置に置かれる。この状態では、ドア3に対するロックは解除されているので、再びドア3を開方向aに移動することができ、再度ロックしたい場合には、操作ノブ23を押し込んで係合爪7を係合位置に移動して突起6に係合させればよい。
【0019】
(乗車時の動作)
ドア3を閉方向bに移動したときに、係合爪7と突起6の係合状態は既に解除されているので、全閉状態のドア3を開く場合には、容易に開くことができる。ドア3が所望範囲開いたらところで操作ノブ23を押し込む。すると、係合爪7が係合位置まで移動して突起と係合するので、ドア3が所望の位置でロックされる。このロックされたドア3を閉方向bに移動することで係合爪7が退避位置に移動して、ドア3のロック状態が解除されドア3を容易に閉じられる。このため、乗車時においても、ドア3を所望の位置にロックできるので、ドア3と、開方向aに位置する隣接物との接触を確実に避けられ、隣接物やドア3の傷並びに破損を防止できる。
【0021】
特にクーペボディーの車両や、左右のドアの形状が非対称に設けられた車両では、セダンタイプの車両よりもサイドドアが大きく形成されタイプもあるので、このような車両にドア開度ロック機構を設けることは、乗降時における隣接物との接触を確実に防止できる。
【0022】
さらに車両の荷室を開閉する、観音開き式のリアドアや1枚ものリアドアを有する車両に適用した場合には、リアドアの開度を所定の開度で確実にロックできるので、自車の後方に停車している車両や、壁や縁石、カードレール等の、車両周部に位置する隣接物との接触を確実に防止できるとともに、荷物の出し入れを容易に行える。本発明は、上述したタイプの車両にその適用範囲を限定するものではなく、車室内や荷室に通じる開口部に開閉自在に支持されたドア全般に適用することができる。
【0023】
【発明の効果】
本発明によれば、ドアが所望の開度で保持されると共に、閉方向への移動に際しては抵抗少なく移動でき、長期に渡って確実にドアを任意の開度でロックでき、ドア閉動作をスムーズに行うことができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a door opening lock mechanism that regulates the opening of a door that is provided at an opening of a vehicle so as to be openable and closable.
[0002]
[Prior art]
A so-called door check device or a mechanism similar thereto is provided between the opening of the vehicle and the door which can be opened and closed so as to prevent the door from opening and closing by its own weight. For example, in Japanese Patent Application Laid-Open No. 7-257186, an engaging means having a plurality of engaging portions arranged in a row along a longitudinal direction is pivotally supported on a body side, and an engaging claw which can be disengaged from the engaging portion is provided on a door. The opening / closing operation of the door is provided so as to be rotatable in the moving direction at the time of opening and closing of the door. There has been proposed a device that applies resistance to the engaging means that moves in accordance with the requirement and regulates the position of the door.
[0003]
[Problems to be solved by the invention]
According to the above-described conventional technology, since the engaging claw is held at a position where it engages with the engaging portion by the elastic means, it is possible to prevent the opening and closing operation of the door due to its own weight. During the movement, the engaging claw receives the elastic force of the elastic means and is also engaged with the engaging portion. For this reason, the engaging claw cannot be selectively disengaged from the engaging portion, and the resistance when closing the door is large, and the door cannot be returned smoothly. In addition, since the engaging claw is urged to the engaging portion by the elastic means, the urging force changes due to the aging of the elastic means, and it is difficult to stably position the door for a long period of time. Further, when a force enough to deform the elastic means is applied, the engaging claw is rotated in any direction of the opening and closing direction of the door and gets over the engaging portion, so that there is a problem in the stopping performance of the door.
SUMMARY OF THE INVENTION An object of the present invention is to provide a door opening lock mechanism that can reliably stop a door at an arbitrary opening for a long period of time and can smoothly perform a door closing operation.
[0004]
[Means for Solving the Problems]
In order to achieve the above object, according to the first aspect of the present invention, a plurality of engaging portions are arranged in a longitudinal direction in one of an opening portion of a vehicle and a door provided in the opening portion so as to be openable and closable. Provided engaging means, when engaging with the engaging portion, an engaging claw that allows movement of the door in the closing direction and prevents movement of the door in the opening direction is provided so as to be disengageable from the engaging portion, Since the engaging claw is configured to be selectively positioned by the control means at an engaging position for engaging with the engaging portion and at a disengagement position for not engaging with the engaging portion, the engaging claw is selectively provided. The door can be located at the engagement position. At the engagement position, movement of the door in the opening direction is restricted, and movement of the door in the closing direction is allowed. For this reason, the door is locked at a desired opening, and can be moved with less resistance when moving in the closing direction.
[0005]
If the engagement portion and the engagement claw are engaged from the door opening of 0 ° (when fully closed), the door cannot be opened, so that the engagement between the two is controlled by at least a passenger in the vehicle. Ensure the degree of opening that allows the means to be operated. For this reason, it is preferable that the operation unit for operating the control means is arranged near the latch arranged inside the door or on the periphery of the opening.
[0006]
As the control means, the operation unit and the engaging claw are connected to each other via a link mechanism to be manually operated, or an electromagnetic actuator for operating the mechanism is provided in the link mechanism, and this electromagnetic actuator is connected to an electric controller. Alternatively, an on / off switch may be connected to this controller to be electrically operated.
[0007]
The present invention may be provided side by side with a well-known door check device arranged on the rotating end side of the door, or may be provided alone. In the case where the door check device is provided together with the door check device, the door check device may be provided so as to function with a smaller opening than the functional opening. For this reason, the opening of the door opening lock mechanism may be the entire opening and closing range of the door to which the present invention is applied, and in the case of a door having a door check device, the opening and closing of the door by this device is restricted. An opening / closing range smaller than the received opening degree is included. Since door check devices generally do not function when the door is slightly opened, it is necessary to consider preventing the door from coming into contact with an adjacent vehicle or an adjacent object such as a curb or wall when getting on or off the vehicle. It is desirable to configure the door opening lock mechanism to function when the door opening is small.
[0008]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.

Has become. The guide member 11 is formed with fixed shafts 13 and 14 and a spring hook portion 15. Since these are provided integrally with the guide member 11, even when an external force acts in the locked state, the relative displacement of the moving lever 5 and the engaging claw 7 can be easily prevented, and the reliability of the device can be improved. Performance can be improved.
[0012]
As shown in FIGS. 1 and 3, the engagement claw 7 has a base end rotatably supported by a fixed shaft 13. A concave portion 7a having a shape similar to the protrusion 6 is formed at the lower end of the tip of the engaging claw 7 to allow the door 3 to move in the closing direction b when engaged with the protrusion 6, and to allow the door 3 to open. The movement to a is prevented. The other end of a tension spring 16 having one end locked to a spring hooking portion 15 is locked to the distal end side of the engagement claw 7, and the engagement claw 7 is turned to the retracted position shown in FIG. Is given.
[0013]
The control means 8 includes an operation lever 17 serving as an operation unit, a first lever 18, a second lever 19, a third lever 20, a connecting rod 21, and a torque spring 22. The operation lever 17 has one end pin-coupled to the first lever 18, and has an operation knob 23 attached to the other end. The operation lever 17 protrudes into the vehicle interior from an interior 24 near a latch (not shown) provided at the entrance 2. ing.
[0014]
The base end of each of the first lever 18 and the second lever 19 is fixed to a support shaft 25 rotatably supported by a base (not shown) of the vehicle. The third lever 20 is rotatably supported by the fixed shaft 14, and has its tip 20 a in contact with the upper part 7 b of the engagement claw 7. The connecting rod 21 has both ends connected to the second lever 19 and the third lever 20 by pins 26 and 27, respectively, and connects the second lever 19 and the third lever 20. The torque spring 22 is composed of a tension spring, one end of which is locked to a pin 26, and the other end of which is locked to a spring pin 28 arranged above the support shaft 25.

[0015]
The spring hook pin 28 is preferably provided on the bisector of the swing range angle of the second lever 19 and on the extension line above the support shaft 25. With this arrangement, the torque spring 22 generates the maximum tension when the second lever 19 swings and is positioned on the bisector, so that the second lever 19 is locked or unlocked. , The tension of the torque spring 22 acts.
[0016]
The operation of the door opening lock mechanism having such a configuration will be described.
(Operation when getting off)
The door 3 is opened in the opening direction a to the extent that the occupant does not touch an adjacent object represented by a vehicle, a wall, a curb, a card rail, etc., and the operation knob 23 is moved from the unlocked position shown in FIG. Push it into the lock position shown. Accordingly, the first lever 18 and the second lever 19 rotate counterclockwise around the support shaft 25 while maintaining a certain angle, and the third lever 20 rotates clockwise around the fixed shaft 14. Rotate. Then, the upper surface 7b of the engaging claw 7 is pushed downward at the tip end 20a, and the engaging claw 7 opposes the urging force of the extension spring 16 from the separated position shown in FIG. 1 to the engaging position shown in FIG. Then, the concave portion 7a engages with the projection 6. Therefore, when the door 3 is to be moved in the opening direction a, the vertical surface 6b of the projection 6 comes into contact with the flat surface 7c of the recess 7a, so that the movement of the moving lever 5 is restricted and the door 3 is locked only in the opening direction. State.
[0017]
As described above, when the desired opening degree of the door 3 is achieved, when the operation knob 23 is depressed, the door 3 is locked at the desired opening degree. Contact can be reliably avoided, and the adjacent object and the door 3 can be prevented from being damaged or damaged.
[0018]
In order to release the engagement between the engaging claw 7 and the projection 6, the locked door 3 is moved in the closing direction b as shown in FIG. Then, the tip of the engaging claw 7 is lifted by the inclined surface 6 a of the projection 6, and the engaging claw 7 is rotated counterclockwise around the fixed shaft 13, and combined with the urging force of the extension spring 16, Is held in the separated position. In addition, the operation of the engagement claw 7 causes the third lever 20 to rotate counterclockwise about the fixed shaft 14, and the second lever 2 is pulled to the left via the connecting rod 21. For this reason, the first lever 18 and the second lever 19 rotate clockwise around the support shaft 25 while maintaining a fixed angle, the operation lever 17 is pushed up, and the operation knob 23 is placed in the unlocked position. . In this state, since the lock on the door 3 has been released, the door 3 can be moved in the opening direction a again, and when it is desired to lock it again, the operating knob 23 is pushed in and the engaging claw 7 is moved to the engaging position. To engage with the protrusion 6.
[0019]
(Operation when riding)
When the door 3 is moved in the closing direction b, the engagement state between the engagement claws 7 and the projections 6 has already been released, so that when the door 3 is fully closed, it can be easily opened. When the door 3 opens in a desired range, the operation knob 23 is pushed in. Then, the engaging claw 7 moves to the engaging position and engages with the projection, so that the door 3 is locked at a desired position. By moving the locked door 3 in the closing direction b, the engaging claw 7 moves to the retracted position, the locked state of the door 3 is released, and the door 3 is easily closed. For this reason, the door 3 can be locked at a desired position even when riding, so that the contact between the door 3 and an adjacent object located in the opening direction a can be reliably avoided, and the adjacent object and the door 3 are not damaged or damaged. Can be prevented.
[0021]
Particularly, in a coupe body vehicle or a vehicle in which the right and left doors are provided asymmetrically, a side door is formed to be larger than a sedan type vehicle. This can reliably prevent contact with an adjacent object at the time of getting on and off.
[0022]
