【産業上の利用分野】
本発明は、車両用アームレストのロック機構に関し、特に、上方開口部を有し小物を収容可能な箱状のアームレスト本体の上方開口部の後端縁に後端部を上下方向へ回動可能に支持されて前記上方開口部を開閉する蓋体の前端部を、前記アームレスト本体の前端縁に解除可能にロックするロック機構に関する。
【0002】
【従来の技術】
この種形式の車両用アームレストのロック機構の一例としては図5に示すように、アームレスト本体1aに設けた掛止手段2aと、蓋体1bに設けた被掛止手段2bと、蓋体1bに設けた操作手段2cと、バネ手段2dとにより構成されており、被掛止手段2bはバネ手段2dの付勢力により掛止手段2aに弾撥的に掛止されて蓋体1bの前端部をアームレスト本体1aにロックし、かつ操作手段2cの回動操作により被掛止手段2bをバネ手段2dに抗して回動させて蓋体1bのアームレスト本体1aに対するロックを解除するようになっている。
【0003】
また、この種形式の車両用アームレストのロック機構の他の一例としては図6に示すように、アームレスト本体1aに設けた掛止手段3aと、蓋体1bに設けた被掛止部3bを有する操作手段3cと、バネ手段3dとにより構成されており、操作手段3cの被掛止部3bはバネ手段3dの付勢力により掛止手段3aに弾撥的に掛止されて蓋体1bの前端部をアームレスト本体1aにロックし、かつ操作手段3cの回動操作により被掛止部3bをバネ手段3dに抗して回動させて蓋体1bのアームレスト本体1aに対するロックを解除するようになっている。
【0004】
【発明が解決しようとする課題】
ところで、これら両ロック機構はいずれも、被掛止手段2b、被掛止部3bの掛止手段2a,3aに対するロック解除方向が車両の進行方向と同じ方向になっている。このため、車両の急制動時、前方への衝突時等車両に前後方向の過大な衝撃力が作用した場合には、車両の慣性力によりアームレスト本体内に収容されている収容物がロック機構、蓋体等に衝突して前後方向の衝撃力を付与することになり、ロック機構の操作手段2c,3cをバネ手段2d,3dに抗して回動操作させまたは蓋体1bを変形させて、被掛止手段2c,被掛止部3cを掛止手段2b,3bから離脱させて、蓋体1bのアームレスト本体1aに対するロックを解除させてしまうという問題がある。従って、本発明の目的は、このような問題に対処することにある。
【0005】
【課題を解決するための手段】
本発明は、上方開口部を有し小物を収容可能な箱状のアームレスト本体の上方開口部の後端縁に後端部を上下方向へ回動可能に支持されて前記上方開口部を開閉する蓋体の前端部を、前記アームレスト本体の前端縁に解除可能にロックするロック機構であり、前記アームレスト本体に設けた掛止手段と、前記蓋体に基端部を左右方向へ回動可能に支持されて前記掛止手段に離脱可能に掛止される被掛止手段と、同被掛止手段を付勢して前記掛止手段に掛止させるバネ手段と、前記被掛止手段に係合する操作アーム部を有し基端部を前記蓋体に前後方向へ回動可能に支持され回動動作により前記被掛止手段を前記バネ手段に抗して回動させて前記掛止手段から離脱させる操作手段と、前記被掛止手段が貫通する穴部を有し前記蓋体に前後方向へ回動可能に支持された回動規制手段を備え、同回動規制手段の穴部を、前後方向に延びて前記被掛止手段が貫通するとともに同回動規制手段の前後方向の回動を許容する縦穴と、同縦穴の中間部にて左右方向に延び前記被掛止手段の左右方向への回動を許容する横穴とにより構成したことを特徴とするものである。
【0006】
【発明の作用・効果】
このように構成したロック機構においては、車両の停止時および通常の走行時には回動規制手段が中立位置にあって、被掛止手段は回動規制手段の穴部の縦穴における横穴に対向する位置にあって、バネ手段の付勢力にて掛止手段に掛止されている。このため、アームレストの蓋体はアームレスト本体にロックされ、操作手段を前後方向への回動操作することにより被掛止手段が横穴内にて左右方向へ回動して掛止手段から離脱する。このため、蓋体のアームレスト本体に対するロックが解除され、アームレスト本体の上側開口部を開放することができる。
【0007】
一方、車両の急制動時、前方に対する衝突時等車両に前後方向の過大な衝撃力が作用した場合には、回動規制手段がその慣性力により前後方向へ回動して被掛止手段を穴部の縦穴における横穴の非対向位置に相対的に移行させる。このため、被掛止手段の左右方向への回動が規制されて掛止手段からの離脱が阻止されて、蓋体のアームレスト本体に対するロック状態が維持される。また、回動規制手段は慣性力が消失すると中立位置に復帰し、被掛止手段は穴部の縦穴における横穴の対向する位置に相対的に移行して左右方向への回動が許容され、バネ手段に抗する操作手段の回動操作により被掛止手段は横穴内にて左右方向へ回動して掛止手段から離脱し、蓋体のアームレスト本体に対するロック状態を解除することができる。
【0008】
【実施例】
以下本発明を図面に基づいて説明するに、図1〜図3には本発明の一実施例に係るロック機構10が示されている。当該ロツク機構10は図4に示すアームレスト20に組付けられているもので、アームレスト20はアームレスト本体21と蓋体22とにより構成されている。アームレスト本体21は前後方向に延びる箱体で小物の収容部を形成しており、また蓋体22はその後端縁部にてアームレスト本体21の後端縁部に上下方向に回動可能に支持されている。当該ロツク機構10はアームレスト本体21と蓋体22との間に組付けられている。
【0009】
ロツク機構10は、掛止手段である掛止部11、被掛止手段である左右一対のフック12,13、バネ手段である左右一対のコイルスプリング14a,14b、操作手段である操作レバー15、および回動規制手段である回動規制部材16を備えている。掛止部11はアームレスト本体21の底部の前部にて起立しており、左右の各方向に延びる突出部11a,11bを備えている。各突出部11a,11bはアームレスト本体21の上側開口部の前縁部に設けられており、またその他の各構成部材12,13,14a,14b,15,16は基板17に組付けられている。基板17は、各構成部材12,13,14a,14b,15,16を組付けられた状態で、蓋体22の前側の開口部22aに嵌合されて固定されている。
【0010】
基板17は底部が前下がりに形成された箱体17aの外周に縁部17bを備えたもので、基板17の底部の後部上面に起立する左右一対の支持部17cが、各支持部17cの外側部に貫通穴17dが、底部の中間部の下面に吊下する前後に対向する2つの支持部17eが左右一対形成されているとともに、基板17の箱体17aの外側部に外側へ突出する左右一対の支持ピン17fが形成されている。
【0011】
各フック12,13は各支持部17eに左右方向へ回動可能に支持され、操作レバー15は各支持部17cに前後方向へ回動可能に支持され、かつ回動規制部材16は各支持ピン17fに前後方向へ回動可能に支持されている。
【0012】
各フック12,13は左右対象に形成されているもので、上端支持部12a,13aと、これから下方へ延びるフック部12b,13bと、上端支持部12a,13aから左右の外側へ延びる掛止部12c,13cを備え、各支持ピン18a,18bを介して各支持部17eに左右方向へ回動可能に支持され、かつ各スプリング14a,14bを介して左右の内側へ付勢されて、各フック部12b,13bの先端部が掛止部11の左右の各突出部11a,11bに掛止されている。
【0013】
操作レバー15は板状の操作部15aの後方の側縁部に左右一対のアーム部15b,15cを備えたもので、各アーム部15b,15cを基板17の各貫通穴17dを貫通させた状態で基板17上に嵌合され、各支持部17cに支持ピン18cを介して前後方向へ回動可能に支持されている。この状態で、各アーム部15b,15cの先端部は各フック12,13の掛止部12c,13cに下方から掛止している。
【0014】
回動規制部材16は円弧状の板部16aと、その左右の中間部から起立するアーム部16b,16cとからなるもので、板部16aには左右一対の穴部16d,16eが形成されているとともに、各アーム部16b,16cには円形穴16b1,16c1と、長穴16b2,16c2とが形成されている。各穴部16d,16eは左右対象の形状に形成されているもので、前後方向に延びる所定幅の縦穴16d1,16e1と、縦穴16d1,16e1の前後の中央部から外側へ延びる所定幅の横穴16d2,16e2とを備えている。縦穴16d1,16e1の左右の幅は各フック12,13のフック部12b,13bが前後方向へ相対移動可能な寸法に設定され、また横穴16d2,16e2の前後方向の幅は各フック12,13のフック部12b,13bが左右方向へ移動可能な寸法に設定されている。
【0015】
回動規制部材16は、各穴部16d,16eに各フック12,13のフック部12b,13bを挿通させた状態で、各アーム部16b,16cの円形穴16b1,16c1を支持ピン17fに嵌合させて前後方向へ回動可能に支持されていて、両長穴16b2,16c2にはバネ棒18dが挿通されている。バネ棒18dは基板17の箱体17aの下面に当接して、回動規制部材16を中立位置に保持している。回動規制部材16が中立位置にある場合には、各フック12,13のフック部12b,13bは縦穴16d1,16e1の中央部に位置して、横穴16d2,16e2に対向しており、各フック12b,13bは左右方向の回動が許容されている。また、回動規制部材16が前後方向へ回動して各フック12,13のフック部12b,13bが縦穴16d1,16e1の中央部から移行すると、各フック部12b,13bは横穴16d2,16e2の対向位置からずれ、各フック12,13は左右方向の回動を規制される。
【0016】
このように構成したロック機構10においては、車両の停止時および通常の走行時には回動規制部材16はバネ棒18dの作用により中立位置にあって、各フック12,13のフック部12b,13bは回動規制部材16の穴部16d,16eにおける横穴16d2,16e2に対向する位置にあり、かつスプリング14a,14bの付勢力により掛止部11の各突出部11a,11bに掛止されている。このため、アームレスト20の蓋体22はアームレスト本体21にロックされ、操作レバー15を前後方向への回動操作すると、各フック12,13が縦穴16d2,16e2内にて左右方向へ回動して掛止部11の各突出部11a,11bから離脱する。このため、蓋体22のアームレスト本体21に対するロックが解除され、アームレスト本体21の上側開口部を開放することができる。
【0017】
一方、車両の急制動時、前方に対する衝突時等車両に前後方向の過大な衝撃力が作用した場合には、回動規制部材16がその慣性力によりバネ棒18dに抗して前後方向へ回動して各フック12,13のフック部12b,13bを穴部16d,16eの横穴16d2,16e2に対する非対向位置に移行させる。このため、各フック12,13の左右方向への回動が規制されて、フック部12b,13bの掛止部11の突出部11a,11bからの離脱が阻止され、蓋体22のアームレスト本体21に対するロック状態が維持される。また、回動規制部材16は慣性力が消失するとバネ棒18dの作用により中立位置に復帰し、各フック部12b,13bは横穴16d2,16e2に対向する位置に移行して左右方向へ回動可能となる。この状態で操作レバー15を回動操作すれば、各フック12,13は横穴16d2,16e2内にて左右方向へ回動して突出部11a,11bから離脱し、蓋体22のアームレスト本体21に対するロック状態を解除することができる。
【0018】
なお、当該ロック機構10においては、左右方向へ回動可能なフック12,13を左右一対設けているため、左右方向から衝撃力が作用した場合には、いずれか一方のフック12,13が掛止部11の突出部11a,11bのいずれかに確実に掛止されるため、左右方向の衝撃力によっても蓋体22のアームレスト本体21に対するロックが維持されて解除されることはない。

The present invention relates to a locking mechanism that releasably locks a front end of a lid that is supported and opens and closes the upper opening to a front edge of the armrest body.
[0002]
[Prior art]
As an example of this type of vehicle armrest locking mechanism, as shown in FIG. 5, a locking means 2a provided on an armrest main body 1a, a locking means 2b provided on a lid 1b, and a lid 1b. The locking means 2b is resiliently locked by the locking means 2a by the biasing force of the spring means 2d, and the front end of the lid 1b is moved. The locking means 2b is locked to the armrest main body 1a, and the locking means 2b is rotated against the spring means 2d by the turning operation of the operating means 2c to release the lock of the lid 1b to the armrest main body 1a. .
[0003]
As another example of this type of vehicle armrest lock mechanism, as shown in FIG. 6, the vehicle armrest has a hooking means 3a provided on the armrest main body 1a and a hooked portion 3b provided on the lid 1b. The operating part 3c and the spring means 3d are constituted, and the latched part 3b of the operating means 3c is resiliently latched to the latching means 3a by the urging force of the spring means 3d, and the front end of the lid 1b is formed. The locking portion is locked to the armrest main body 1a, and the locking portion 3b is turned against the spring means 3d by the turning operation of the operating means 3c to release the lock of the lid 1b to the armrest main body 1a. ing.
[0004]
[Problems to be solved by the invention]
By the way, in both of these lock mechanisms, the unlocking direction of the locking means 2b and the locking portion 3b with respect to the locking means 2a, 3a is the same as the traveling direction of the vehicle. Therefore, when an excessive impact force in the front-rear direction is applied to the vehicle at the time of sudden braking of the vehicle, at the time of a forward collision, etc., the contents accommodated in the armrest body are locked by the inertia force of the vehicle, The impact force in the front-rear direction is applied by colliding with the lid or the like, and the operating means 2c, 3c of the lock mechanism is rotated or operated against the spring means 2d, 3d or the lid 1b is deformed. There is a problem that the locking means 2c and the locking portion 3c are detached from the locking means 2b and 3b, and the lock of the lid 1b to the armrest main body 1a is released. Accordingly, it is an object of the present invention to address such problems.
[0005]
[Means for Solving the Problems]
According to the present invention, a rear end of a box-shaped armrest body having an upper opening and capable of accommodating small articles is supported by a rear end of the upper opening so as to be rotatable in a vertical direction to open and close the upper opening. A lock mechanism for releasably locking the front end of the lid to the front edge of the armrest main body, and a hooking means provided on the armrest main body, and a base end of the lid capable of rotating in the left-right direction. A latching means which is supported and detachably latched to the latching means, a spring means for urging the latching means to latch the latching means, and a latching means. A base end portion rotatably supported in the front-rear direction by the lid body, and a rotatable operation for rotating the latching means against the spring means so that the latching means Operating means for detaching from the cover, and a hole through which the hooked means penetrates; Movably supported rotation restricting means, extending in the front-rear direction through the hole of the rotation restricting means, allowing the hooked means to penetrate, and permitting the rotation restricting means to rotate in the front-rear direction. And a horizontal hole extending in the left-right direction at an intermediate portion of the vertical hole and allowing the locking means to rotate in the left-right direction.
[0006]
[Action and Effect of the Invention]
In the lock mechanism configured as described above, when the vehicle is stopped and when the vehicle is traveling normally, the rotation restricting means is in the neutral position, and the locking means is located at a position facing the horizontal hole in the vertical hole of the hole of the rotation restricting means. In the above, the latching means is locked by the biasing force of the spring means. For this reason, the lid of the armrest is locked to the armrest main body, and when the operating means is rotated in the front-rear direction, the hooked means is rotated left and right in the lateral hole and detaches from the hooking means. For this reason, the lock of the lid to the armrest main body is released, and the upper opening of the armrest main body can be opened.
[0007]
On the other hand, when an excessive impact force in the front-rear direction is applied to the vehicle at the time of sudden braking of the vehicle, such as at the time of a collision with the front, the rotation restricting means is rotated in the front-rear direction by the inertia force and the locking means The hole is relatively shifted to a non-opposing position of the horizontal hole in the vertical hole of the hole. For this reason, the rotation of the hooked means in the left-right direction is restricted, the detachment from the hooking means is prevented, and the locked state of the lid to the armrest body is maintained. In addition, the rotation restricting means returns to the neutral position when the inertial force disappears, the latching means relatively shifts to a position where the horizontal hole in the vertical hole of the hole opposes, and rotation in the left and right direction is allowed, By the turning operation of the operating means against the spring means, the hooked means turns left and right in the lateral hole and separates from the hooking means, so that the locked state of the lid to the armrest body can be released.

For this reason, the lid 22 of the armrest 20 is locked to the armrest main body 21, and when the operation lever 15 is rotated in the front-rear direction, the hooks 12 and 13 are rotated left and right in the vertical holes 16d2 and 16e2. The hook portion 11 is separated from the projecting portions 11a and 11b. Therefore, the lock of the lid 22 to the armrest main body 21 is released, and the upper opening of the armrest main body 21 can be opened.
[0017]
On the other hand, when an excessive impact force in the front-rear direction is applied to the vehicle at the time of sudden braking of the vehicle or at the time of a collision with the front, the rotation restricting member 16 is rotated in the front-rear direction against the spring rod 18d by its inertia force. The hook portions 12b and 13b of the hooks 12 and 13 are moved to non-opposing positions with respect to the side holes 16d2 and 16e2 of the holes 16d and 16e. For this reason, the rotation of the hooks 12 and 13 in the left-right direction is restricted, and the hooks 12 b and 13 b are prevented from coming off the protrusions 11 a and 11 b of the hook 11, and the armrest main body 21 of the lid 22 is prevented. Is locked. When the inertia force disappears, the rotation restricting member 16 returns to the neutral position by the action of the spring bar 18d, and the hooks 12b and 13b move to positions facing the side holes 16d2 and 16e2 and can rotate in the left-right direction. It becomes. If the operation lever 15 is turned in this state, the hooks 12 and 13 turn left and right in the lateral holes 16d2 and 16e2, disengage from the protrusions 11a and 11b, and move the lid 22 to the armrest body 21. The locked state can be released.
[0018]
Since the lock mechanism 10 has a pair of left and right hooks 12 and 13 rotatable in the left and right directions, when an impact force acts from the left and right directions, one of the hooks 12 and 13 is engaged. Since the locking portion is securely hooked to one of the protruding portions 11a and 11b of the stopping portion 11, the locking of the lid 22 to the armrest main body 21 is not released even by the impact force in the left-right direction.
