Description

本発明は、車両用のドアを任意の開度位置に保持するための装置、特に詳述すれば、ドアを任意の位置で保持できかつドアを軽く動かすことのできる車両用ドア開閉位置保持装置に関する。   The present invention relates to a device for holding a vehicle door at an arbitrary opening position, and more particularly, a vehicle door opening / closing position holding device that can hold the door at an arbitrary position and lightly move the door. About.

車両用ドアの開閉に際し、ドアを任意の開度位置に保持することが求められる。このため、従来のドア開閉位置保持装置は、特許文献１に示されるように、車両のボデーとドアとの間にレバーを配し、レバーの一端を一般にはボデーに回動自在に支持し、他端をドアパネルを貫通してドアの内部へと延在させ、ドアパネルの内側に配したケース内のシューをレバーと摺接関係とさせている。
この装置では、シューがプレートを介してスプリングの付勢力を受ける構成であって、さらに、ドアの開閉操作に応じプレートとシューとの当たり面を変えシューとレバーとの摩擦力を変化させている。即ち、ドア開閉操作の初期段階では、ドアの保持荷重が大であり（ドアの動かし始めは重く）、その後はドアを軽く操作できるものである。 When opening and closing a vehicle door, it is required to hold the door at an arbitrary opening position. For this reason, as shown in Patent Document 1, a conventional door opening / closing position holding device is provided with a lever between a vehicle body and a door, and generally supports one end of the lever rotatably on the body, The other end extends through the door panel into the door, and the shoe in the case disposed inside the door panel is in sliding contact with the lever.
In this device, the shoe is configured to receive the biasing force of the spring via the plate, and the contact surface between the plate and the shoe is changed according to the door opening / closing operation to change the frictional force between the shoe and the lever. . That is, in the initial stage of the door opening / closing operation, the door holding load is large (heavier when the door starts to move), and thereafter the door can be operated lightly.

シューに代えて、特許文献２に示されるように、ボールや振り子のような押圧部材を用いる例もある。   In place of the shoe, there is an example in which a pressing member such as a ball or a pendulum is used as disclosed in Patent Document 2.

特開２００４−１００２７９号公報Japanese Patent Laid-Open No. 2004-1000027 特開平２−８４７９号公報Japanese Patent Laid-Open No. 2-8479

従来のドア開閉位置保持装置では、前述した如く、シューをレバーに当接させるものであるから、スプリングの付勢力に応じてドアの動かし始めの荷重を上げドアの操作を重くさせ得ても、その後につづくドア操作を軽くさせることができず、常に重たい感じをドア操作者に与える。   In the conventional door opening / closing position holding device, as described above, the shoe is brought into contact with the lever. Subsequent door operations cannot be made lighter and always give the door operator a heavy feeling.

逆に、ドア開閉操作中にドアを軽く操作できるようにすると、ドアの動かし始めも軽くなり、ドアを任意位置に保持できないことになる。又、摩擦力を変化させるためにプレートとシューの当たり面を変えているので、シューのレバーに対する摺接がぎこちなくなり、結果、ドアのスムーズな開閉操作が阻害される恐れがある。
それ故に、本発明は、前述した従来技術の不具合を解消させることを解決すべき課題とする。 On the other hand, if the door can be operated lightly during the door opening / closing operation, the start of the movement of the door becomes light and the door cannot be held at an arbitrary position. Further, since the contact surface between the plate and the shoe is changed in order to change the frictional force, the sliding contact with the lever of the shoe becomes awkward, and as a result, the smooth opening / closing operation of the door may be hindered.
Therefore, this invention makes it the subject which should be solved to eliminate the malfunction of the prior art mentioned above.

本発明は前述した課題を解決するために、基本的には車両のボデーに一端が固定されたレバーに第１のホイールを摺接させ、増速装置を介して第２のホイールを摩擦部材に摺接させる手段を採用する。
該手段の採用は、両ホイールの動かし始めの静摩擦は大であるが、摺動速度の増大により両ホイール、特に第２のホイールの動摩擦は低減し、ドアの開閉操作を軽いものとさせることができる。又、ドアの開閉位置の保持も任意位置での保持を可能にさせる。 In order to solve the above-mentioned problems, the present invention basically brings the first wheel into sliding contact with a lever fixed at one end to a vehicle body, and the second wheel is made into a friction member via a speed increasing device. A means for sliding contact is adopted.
The use of this means has a large static friction at the beginning of movement of both wheels, but the sliding friction increases the dynamic friction of both wheels, especially the second wheel, and makes the door opening / closing operation light. it can. In addition, it is possible to hold the door in the open / closed position at an arbitrary position.

本発明によれば、一端が車両のボデーに支持されかつ自由端がドアに固定されたケースを貫通するレバーと、ケース内に配されかつその外周面がレバーに圧接する第１のホイールと、ケース内に配されかつ第１のホイールに連結された増速装置と、ケース内に配されかつ増速装置に連結された第２のホイールと、第２のホイールの外周面に圧接するようケースに保持された摩擦部材とを有する車両用ドア開閉位置保持装置が提供される。 According to the present invention, a lever extending through the one end and the free end is supported on the body of the vehicle is fixed to the door case, a first wheel arranged and having an outer peripheral surface thereof in the case contact pressure lever, a speed increasing device arranged and having connected to the first wheel in the case, and a second wheel connected to disposed and having the speed increasing device into the case, the case so as to contact pressure with the outer peripheral surface of the second wheel There is provided a vehicular door opening / closing position holding device having a friction member held on the vehicle.

好ましくは、増速装置が第１のホイールと同軸の第１のギヤと、第２のホイールと同軸にしてかつ第１のギヤと噛合う第２のギヤとからなる。又、第１のギヤの歯数が第２のギヤの歯数より大であり、第１のホイールの径が第２のホイールの径より大である。   Preferably, the speed increasing device includes a first gear coaxial with the first wheel, and a second gear coaxial with the second wheel and meshing with the first gear. The number of teeth of the first gear is larger than the number of teeth of the second gear, and the diameter of the first wheel is larger than the diameter of the second wheel.

増速装置として、第１と第２のホイールを支持する軸に固定された対のプーリーと、両プーリーを巻回するベルトよりなるものとすることができる。   The speed increasing device may be composed of a pair of pulleys fixed to a shaft that supports the first and second wheels, and a belt around which both pulleys are wound.

本発明によれば、任意位置でのドア保持が可能で、ドア保持時の静摩擦が大で、ドア保持荷重は大きく、ドアの開閉操作が進むとレバーと第１のホイールとの摺動速度が増大し、第２のホイールと摩擦部材の動摩擦が低下し、ドアの開閉操作は容易となる。又、第１ホイールはレバーと常に一定の摺接を成しているので、摩擦力の変化によってドアのスムーズな開閉操作が阻害されることもない。   According to the present invention, the door can be held at an arbitrary position, the static friction at the time of holding the door is large, the door holding load is large, and the sliding speed between the lever and the first wheel increases as the door opening / closing operation proceeds. The dynamic friction between the second wheel and the friction member decreases, and the door opening / closing operation becomes easy. Further, since the first wheel is always in constant sliding contact with the lever, the smooth opening / closing operation of the door is not hindered by the change of the frictional force.

増速装置は、その増速率を任意に変更させ得るので、基本構成を同じとさせ増速装置のみを変えることで各種の車に本装置を適用できる。   Since the speed increasing device can arbitrarily change the speed increasing rate, this device can be applied to various vehicles by changing the speed increasing device only with the same basic configuration.

車両ボデー１とドア２とはヒンジ３，３を用いて連結され、ドア２の開閉操作を可能とさせる。ボデー１とドア２との間にはドアの開閉位置を保持させるための装置４が設けられ、該装置４によりドア２を任意の開度位置に保持可能とさせる。
装置４は、図１乃至３に示すように、一端をボデー１に枢支しかつ他端をドア２のドアパネル２ａを介してドア２の内部へと延在させるレバー５を有す。図２に示す如く、ドア２のドアパネル２ａの内側にはケース６が固定され、レバー５の一部がケース６を貫通する。 The vehicle body 1 and the door 2 are connected using hinges 3 and 3 so that the door 2 can be opened and closed. A device 4 for holding the open / close position of the door is provided between the body 1 and the door 2, and the device 4 can hold the door 2 at an arbitrary opening position.
As shown in FIGS. 1 to 3, the device 4 has a lever 5 having one end pivotally supported by the body 1 and the other end extending into the door 2 through the door panel 2 a of the door 2. As shown in FIG. 2, the case 6 is fixed inside the door panel 2 a of the door 2, and a part of the lever 5 penetrates the case 6.

ケース６内に対の離間した軸７，８が配され、軸７には第１のホイール９と第１のギヤ１０が、軸８には第２のホイール１１と第２のギヤ１２とが保持される。
増速装置１３を構成する両ギヤ１０，１２は噛合し、第１のギヤ１０の歯数は第２のギヤ１２の歯数より大である。かくして、軸７の回転は増速装置１３を介して増速して軸８に伝達される。
軸７には大径の第１のホイール９が固定され、第１のホイール９がレバー５と摺接関係となっている。レバー５はガイド１４と第１のホイール９とにより振れが防止され、かつストッパ１５によりそのストロークが規制される。 A pair of spaced shafts 7 and 8 are arranged in the case 6, the shaft 7 includes a first wheel 9 and a first gear 10, and the shaft 8 includes a second wheel 11 and a second gear 12. Retained.
The gears 10 and 12 constituting the speed increasing device 13 are engaged with each other, and the number of teeth of the first gear 10 is larger than the number of teeth of the second gear 12. Thus, the rotation of the shaft 7 is accelerated through the speed increasing device 13 and transmitted to the shaft 8.
A large-diameter first wheel 9 is fixed to the shaft 7, and the first wheel 9 is in sliding contact with the lever 5. The lever 5 is prevented from shaking by the guide 14 and the first wheel 9, and its stroke is regulated by the stopper 15.

軸８に固定された小径の第２のホイール１１は、ケース６に保持された摩擦部材１６に摺接し、第２のホイール１１の回転に対し抵抗を与える。
増速装置１３として、図示例は対のギヤ１０，１２を用いたが、ギヤ１０，１２に代えてプーリーを用い両プーリーにベルトを巻回してもよく、又、摩擦車を用いてもよい。軸７の回転が軸８に増速されて伝達されるものであればよい。 The small-diameter second wheel 11 fixed to the shaft 8 is in sliding contact with the friction member 16 held by the case 6 and provides resistance to the rotation of the second wheel 11.
In the illustrated example, the pair of gears 10 and 12 is used as the speed increasing device 13. However, instead of the gears 10 and 12, pulleys may be used, belts may be wound around both pulleys, or a friction wheel may be used. . What is necessary is that the rotation of the shaft 7 is accelerated and transmitted to the shaft 8.

ドア２が任意の開度位置に保持されているとき、レバー５は第１のホイール９に所定の荷重の下で接しかつ第２のホイール１１が摩擦部材１６と所定の荷重の下で接している。よって、ドア２の振れや不用意な開閉はない。
ドア２の開閉操作をなすと、ボデー１に保持されたレバー５に対してドア２が相対的に動き、第１のホイール９がレバー５に対して摺接し、この第１のホイール９の回転は軸７、増速装置１３を介して増速して軸８に伝達され、第２のホイール１１の摩擦部材１６に対する摺動速度を増大させることになる。これにより、動摩擦が減少しドア２の操作が軽くなっていく。即ち、ドア２の動かし始めは重く、動かすにつれ軽くなるというドア２の開閉特性が得られる。 When the door 2 is held at an arbitrary opening position, the lever 5 contacts the first wheel 9 under a predetermined load and the second wheel 11 contacts the friction member 16 under a predetermined load. Yes. Therefore, there is no swing of the door 2 or inadvertent opening / closing.
When the door 2 is opened and closed, the door 2 moves relative to the lever 5 held by the body 1, and the first wheel 9 comes into sliding contact with the lever 5, and the rotation of the first wheel 9 is performed. Is increased through the shaft 7 and the speed increasing device 13 and transmitted to the shaft 8 to increase the sliding speed of the second wheel 11 with respect to the friction member 16. Thereby, dynamic friction decreases and the operation of the door 2 becomes lighter. That is, the opening / closing characteristic of the door 2 is obtained such that the door 2 starts to move and is lighter as it is moved.
