The pendulum (16) is then mechanically connected to a damper (23) suitable for dampening the swing of the pendulum (16).

Description

本発明は、ドア等のハンドルに関するものであり、特に、このハンドルは、自動車のドアをロック解除すると同時に開扉するために用いることができ、且つ、事故の際にこのドアが誤って開扉されることを防ぐ、加速力に応じて自動的になされる安全装置が設けられたレバーハンドルに関するものである。   The present invention relates to a handle such as a door, and in particular, the handle can be used for unlocking a door of an automobile and opening the door at the same time, and the door is erroneously opened in the event of an accident. The present invention relates to a lever handle provided with a safety device that is automatically made according to an acceleration force to prevent this from occurring.

本願と同じ出願人名義の欧州特許出願公開第１５５６５６９号明細書には、車両のドアに固定されたフレーム内で回転できるレバーを備えるハンドルが開示されている。このレバーは、ドアのロックを解除するためにレバーが引かれるとフレーム内で回転することができる揺動体（rocker）に機械的に連結されている。揺動体には、肩部が設けられており、肩部は、慣性質量体が設けられた振り子を有する固定部材のストッパ片によって制止されるのに適している。このため、ストッパ片は、この慣性質量体を推す慣性力が慣性質量体に作用することによって振り子に強い振れ（oscillation）が引き起こされている間、肩部を制止する。この構成により、自動車が側面衝突を受けている間、レバーを推す慣性力がレバーに作用するため、誤ってハンドルが開放されて、ひいてはドアが開扉されることができなくなる。   EP 1 556 569 in the name of the same applicant as the present application discloses a handle provided with a lever which can be rotated in a frame fixed to a door of a vehicle. The lever is mechanically coupled to a rocker that can rotate within the frame when the lever is pulled to unlock the door. The swing body is provided with a shoulder portion, and the shoulder portion is suitable for being restrained by a stopper piece of a fixing member having a pendulum provided with an inertia mass body. For this reason, the stopper piece restrains the shoulder while a strong oscillation is caused to the pendulum by the inertial force that pushes the inertial mass acting on the inertial mass. With this configuration, since the inertial force that pushes the lever acts on the lever while the automobile is undergoing a side collision, the handle is accidentally opened, and thus the door cannot be opened.

しかしながら、この公知のハンドルの固定部材は、常に正確に作用するとは限らない。というのは、振り子が、自動車の衝突中に、例えば、慣性質量体に作用する加速度が急激に変化したり、又は振り子が跳ね返ったりすることによって、その通常の位置に戻ることがあるためである。言い換えれば、慣性質量体の作用をレバーの動きと同期させること、及び／又は、振り子を十分な時間にわたりハンドルを固定する位置に保つことは、常に可能であるとは限らない。   However, this known handle fixing member does not always work accurately. This is because the pendulum may return to its normal position during a car crash, for example, when the acceleration acting on the inertial mass changes suddenly or the pendulum rebounds. . In other words, it is not always possible to synchronize the action of the inertial mass with the movement of the lever and / or to keep the pendulum in a position to fix the handle for a sufficient time.

それ故、本発明の目的は、上述の欠点のないハンドルを提供することである。この目的は、主な特徴が請求項１に開示され、他の特徴がそれに続く請求項に開示されているハンドルによって実現される。   The object of the present invention is therefore to provide a handle which does not have the above-mentioned drawbacks. This object is achieved by a handle whose main features are disclosed in claim 1 and whose other features are disclosed in subsequent claims.

振り子に機械的に接続されるダンパーの影響によって、本発明に係るハンドルは、自動車の衝突が終わるまで固定部材を固定位置に留める。この構成により、ハンドルは、衝突中は常にロックされており、衝突が終わると自動的にロックが解除される。   Due to the influence of the damper mechanically connected to the pendulum, the handle according to the invention keeps the fixing member in a fixed position until the end of the car crash. With this configuration, the handle is always locked during the collision, and is automatically unlocked when the collision ends.

本発明の特定の形態によれば、ダンパーは、一つの方向に作用するものが好ましく、これにより、固定部材は、ダンパーが圧縮を受けている間、ダンパーによって妨げを受けることがなく、それ故レバーをほとんど瞬間的に固定することができる。   According to a particular form of the invention, the damper preferably acts in one direction, so that the fixing member is not disturbed by the damper while the damper is under compression and is therefore The lever can be fixed almost instantaneously.

ダンパーは、振り子及びフレームの間に設けられることが好ましく、振り子に作用する弾性手段と同じ方向に作用することが好ましい。このため、公知のハンドルもまた、本発明に係る装置を容易に備えることができる。   The damper is preferably provided between the pendulum and the frame, and preferably acts in the same direction as the elastic means acting on the pendulum. For this reason, known handles can also easily be provided with the device according to the invention.

また、本発明に係るハンドルのさらなる利点及び特徴が、添付の図面に関する、本発明の実施形態についての以下の詳細な説明であり且つ限定的でない説明から、当業者には明らかになるであろう。   Further advantages and features of the handle according to the invention will also become apparent to those skilled in the art from the following detailed and non-limiting description of embodiments of the invention with reference to the accompanying drawings. .

通常位置にあるハンドルの長手方向断面を示す。Figure 3 shows a longitudinal section of the handle in the normal position. 図１のハンドルの平面ＩＩ−ＩＩに沿った断面図を示す。Fig. 2 shows a cross-sectional view of the handle of Fig. 1 along the plane II-II. 衝突位置にあるハンドルの長手方向断面を示す。Fig. 5 shows a longitudinal section of the handle in the collision position. 図３のハンドルの平面ＩＶ−ＩＶに沿った断面図を示す。Fig. 4 shows a cross-sectional view along the plane IV-IV of the handle of Fig. 3;

図１及び２を参照すると、本発明に係るハンドルが、例えば自動車のドア２の外表面の裏側に固定されるのに適したフレーム１を公知の方法で備えていることが分かる。フレーム１には、支点として作用する横断ピン３が設けられている。そして、横断ピン３を中心として、レバー５の成形による伸張部４が回転することができ、レバー５は、ドア２を開扉するために、矢印６の方向へと外側に引かれるのに適している。これ故、レバー５は、ドア２の回転軸と実質的に平行な第１の軸７を中心として回転する。レバー５の他方の端部には付属部８が設けられ、付属部８は、フレーム１の中に突出すると共に凹部９を備え、この凹部９には舌部１０が回転可能に係合する。舌部１０は揺動体１１の一方の側面から突出し、揺動体１１は、軸７と実質的に垂直な第２の軸１２を中心にして、フレーム１内で回転することができる。この構成によれば、レバー５は揺動体１１と機械的に連結され、そのため、レバー５が引かれると、揺動体１１が軸１２を中心として回転する。揺動体１１には、コイルばね１３が同軸になるように配置される。コイルばね１３により、揺動体１１は、レバー５がそれ以上引かれない場合、レバー５と共に元来の位置に戻される。揺動体１１はさらにドア２のロック解除機構（図示せず）と連結され、そのため、レバー５をさらに引くことによって、ドア２を開扉できる。上述の連結は、例えば、揺動体１１が回転している間に揺動体１１によって引かれるケーブル（図示せず）を用いて行われる。   1 and 2, it can be seen that the handle according to the invention comprises, in a known manner, a frame 1 suitable for being fixed, for example, on the back side of the outer surface of an automobile door 2. The frame 1 is provided with a transverse pin 3 that acts as a fulcrum. And the extension part 4 by the shaping | molding of the lever 5 can rotate centering | focusing on the crossing pin 3, and the lever 5 is suitable for being pulled outside in the direction of arrow 6 in order to open the door 2. ing. Therefore, the lever 5 rotates around the first axis 7 that is substantially parallel to the rotation axis of the door 2. An attachment portion 8 is provided at the other end of the lever 5, and the attachment portion 8 protrudes into the frame 1 and includes a recess 9, and a tongue 10 is rotatably engaged with the recess 9. The tongue 10 protrudes from one side surface of the oscillating body 11, and the oscillating body 11 can rotate within the frame 1 about a second shaft 12 that is substantially perpendicular to the shaft 7. According to this configuration, the lever 5 is mechanically coupled to the rocking body 11, so that when the lever 5 is pulled, the rocking body 11 rotates about the shaft 12. A coil spring 13 is arranged on the rocking body 11 so as to be coaxial. The oscillating body 11 is returned to the original position together with the lever 5 by the coil spring 13 when the lever 5 is not pulled any more. The swinging body 11 is further connected to a lock release mechanism (not shown) of the door 2, so that the door 2 can be opened by further pulling the lever 5. The above-described connection is performed using, for example, a cable (not shown) that is pulled by the rocking body 11 while the rocking body 11 is rotating.

揺動体１１には好ましくは、タペット１５が摺動できるカム面１４が設けられる。このタペット１５は、特にフレーム１又はフレーム１と一体となった本体に対して回転する振り子１６を備える固定部材のアームの一端部に配置される。それ故、振り子１６は、揺動体１１が軸１２を中心として回転するときにレバー５が回転の中心とする軸７に実質的に平行な第３の軸１７を中心に振れ動く。振り子１６の他方の端部には慣性質量体１８が設けられ、慣性質量体１８は、好ましくは平坦な形状を有し、フレーム１の中央近傍に配置される。弾性手段１９、特に、振り子１６とフレーム１との間で長手方向軸が軸１７と実質的に垂直となるように配置されるコイルばねは、振り子１６に対して力を及ぼすことで、振り子１６をその通常位置に向けて押す。この通常位置というのは、タペット１５が、付勢されて揺動体１１のカム面１４に対して押しつけられる位置のことである。揺動体１１には好適に肩部２０が設けられ、この肩部２０は、振り子１６のタペット１５の高さより大きい距離だけカム面１４から離れたところに配置されている。それ故、タペット１５は、カム面１４を摺動する場合には肩部２０と接触することなく肩部２０の下を通る。その一方、タペット１５は、特に振り子１６が振れることによってカム面１４から離れると、肩部２０を制止することにより、ストッパ片として作用し、揺動体１１の回転を阻止する。通常の使用では、レバー５が矢印６の方向に手動で引かれると、揺動体１１は矢印２１の方向に回転し、そのため、タペット１５が、肩部２０に干渉することなくカム面１４上を摺動する。   The rocking body 11 is preferably provided with a cam surface 14 on which the tappet 15 can slide. The tappet 15 is disposed at one end of an arm of a fixed member that includes a pendulum 16 that rotates relative to the frame 1 or the main body integrated with the frame 1. Therefore, the pendulum 16 swings around the third shaft 17 that is substantially parallel to the shaft 7 that the lever 5 rotates about when the rocking body 11 rotates about the shaft 12. An inertia mass body 18 is provided at the other end of the pendulum 16, and the inertia mass body 18 preferably has a flat shape and is arranged near the center of the frame 1. The spring means 19, in particular a coil spring arranged so that its longitudinal axis is substantially perpendicular to the axis 17 between the pendulum 16 and the frame 1, exerts a force on the pendulum 16, Press toward its normal position. This normal position is a position where the tappet 15 is urged and pressed against the cam surface 14 of the rocking body 11. The rocking body 11 is preferably provided with a shoulder portion 20, and the shoulder portion 20 is disposed away from the cam surface 14 by a distance larger than the height of the tappet 15 of the pendulum 16. Therefore, the tappet 15 passes under the shoulder 20 without contacting the shoulder 20 when sliding on the cam surface 14. On the other hand, the tappet 15 acts as a stopper piece by stopping the shoulder portion 20, particularly when the pendulum 16 is separated from the cam surface 14 due to the swing of the pendulum 16, thereby preventing the swinging body 11 from rotating. In normal use, when the lever 5 is manually pulled in the direction of the arrow 6, the oscillator 11 rotates in the direction of the arrow 21, so that the tappet 15 moves over the cam surface 14 without interfering with the shoulder 20. Slide.

本発明によれば、振り子１６は、振り子１６の振れを減衰するのに適したダンパー２３のピストン２２に機械的に接続されている。ダンパー２３は、一方向に作用するものが好ましく、すなわち、その伸びに抗する力が圧縮に抗する力より大きくなっている。特に、ピストン２２は、慣性質量体１８に対して回転可能に設けられ、振り子１６の回転軸１７に実質的に垂直な軸に沿って、具体的には、コイルばね１９の長手方向軸に実質的に平行な軸に沿って、摺動することができる。ダンパー２３は、振り子１６及びフレーム１の間に配置される。   According to the invention, the pendulum 16 is mechanically connected to a piston 22 of a damper 23 suitable for dampening the swing of the pendulum 16. The damper 23 is preferably one that acts in one direction, that is, the force resisting its elongation is greater than the force resisting compression. In particular, the piston 22 is provided so as to be rotatable with respect to the inertial mass 18 and substantially along the axis substantially perpendicular to the rotation axis 17 of the pendulum 16, specifically to the longitudinal axis of the coil spring 19. Can slide along parallel axes. The damper 23 is disposed between the pendulum 16 and the frame 1.

図３及び４を参照すると、事故の際、レバー５が、それを矢印６の方向に開放させようとするような推される力を受けた場合に、慣性質量体１８もまた同じ推される力を受け、その結果、振り子１６が弾性手段１９の力に打ち勝つことにより、タペット１５が矢印２４の方向に動かされてカム面１４から離れるように、振り子１６が振れる。タペット１５は、その新しい位置では、揺動体１１がレバー５によって引かれて回転し始める際、肩部２０を制止して固定し、そのため、揺動体１１の完全な回転が阻まれる。揺動体１１は、それ以上回転することができないため、ドア２のロック解除機構を作動させることがない。このため、ドア２が誤って開扉されることが防止される。ダンパー２３は、振り子１６が振れる動きを減衰し、及び／又は、弾性手段１９が拡がる動きを止める。なお、弾性手段１９が拡がることによって、タペット１５は、肩部２０から離れる方向に移動させられる。衝突の終わりには、振り子１６は、元の位置にゆっくりと戻り、それによって、肩部２０からタペット１５が解放され、レバー５を引けばドア２の開扉が可能になる。   Referring to FIGS. 3 and 4, in the event of an accident, if the lever 5 is subjected to a thrust force that attempts to open it in the direction of arrow 6, the inertia mass 18 is also thrust the same. As a result, when the pendulum 16 overcomes the force of the elastic means 19, the pendulum 16 is swung so that the tappet 15 is moved in the direction of the arrow 24 and away from the cam surface 14. In the new position, the tappet 15 stops and fixes the shoulder 20 when the swinging body 11 is pulled by the lever 5 and starts to rotate, so that complete rotation of the swinging body 11 is prevented. Since the oscillating body 11 cannot rotate any more, the unlocking mechanism of the door 2 is not operated. For this reason, it is prevented that the door 2 is opened accidentally. The damper 23 attenuates the movement of the pendulum 16 and / or stops the movement of the elastic means 19 expanding. The tappet 15 is moved away from the shoulder 20 by the expansion of the elastic means 19. At the end of the collision, the pendulum 16 slowly returns to its original position, thereby releasing the tappet 15 from the shoulder 20 and pulling the lever 5 allows the door 2 to open.

以上開示及び例示された本発明の実施形態に対し、本発明の範囲内にある、可能な変形及び／又は追加が当業者によって行われ得る。   To the embodiments of the invention disclosed and exemplified above, possible modifications and / or additions within the scope of the invention may be made by those skilled in the art.
