- a push-push type sometimes referred to as a push-lock / push-open type
- a safety device capable of holding the movable body in a fixed position in the main body even if it is temporarily released by a load such as an impact applied to the latch device from the outside (synonymous with inertial force, herein
- a push-push type latch device locks a movable body such as a lid against the main body by a push operation against the urging force of the urging means at a fixed position (usually closed position) of the main body. The locking is released.
- This latch device is easy to use because it can be locked and released by pushing the movable body.
- the countermeasures are roughly classified into an internal type (for example, Japanese Patent No. 2912433) in which a safety function is added to the latch device itself and a dedicated type that is independent from the latch device exemplified in Patent Document 1 and the like. Note that the internal type is more likely to be restricted by safety performance and accuracy because the constituent members are arranged in the latch case than the dedicated type.
- FIG. 12 shows the safety device of Patent Document 1, wherein (a) shows a state where no inertial force is applied, and (b) shows a state where an inertial force is applied.
- This entire structure includes a housing H opened on the left side, a movable body (storage box) B, a biasing means (not shown) that biases the movable body B in the opening direction, and a push-push type latch device (not shown).
- the latch device is used to lock the movable body B in the closing position of the housing H by a push operation against an urging force, and to unlock the movable body B by the next push operation. To move to.
- the safety device includes a rotating body 1 that is pivotally supported on a housing H by a shaft member 3 and is urged in one direction via a spring 2, and an inertial response body 4 that is variable between a standby position and an operating position.
- a rotating body 1 that is pivotally supported on a housing H by a shaft member 3 and is urged in one direction via a spring 2, and an inertial response body 4 that is variable between a standby position and an operating position.
- the applicant has previously developed Japanese Patent Application Laid-Open No. 2007-308977 as a safety device in order to reliably prevent malfunction of a push-push type latch device.
- Another object of the present invention is to further improve the safety performance and accuracy as a safety device, and to increase the application by increasing the reliability of the target push-push type latch device.
- the present invention locks the movable body at a fixed position of the main body by a push operation against the urging force of the urging means with respect to the main body, and releases the lock by the next push operation.
- the push-push type latch device is used together with a circulating cam groove provided on one of the main body and the movable body and having a reciprocating groove portion and a locking groove portion, and the main body and the movable body.
- a response member having a pin that traces the circulation cam groove provided on the other side, and when the response member receives a load such as an impact, the pin is disengaged from the reciprocation groove portion of the circulation cam groove.
- “transition to the locking groove portion so as not to return” means that the inertial force is once transferred from the reciprocating groove portion to the locking groove portion when the response member receives a load (inertial force) such as an impact. Even if it disappears (for example, unless a push operation is performed on the movable body as shown in the form), it means that the locking groove portion does not return to the reciprocating groove portion.
- the above safety devices are quite different from the conventional device as a countermeasure against malfunction caused by the inertial force of the push-push type latch device.
- the conventional device when the latch device receives an inertial force in the same direction as the push operation for unlocking in the locked state, the movement of the related members is prevented so as not to switch from the locked state to the unlocked state. Is.
- the device of the present invention allows the latch device to switch from the locked state to the unlocked state by the inertial force, and even if the latch device is released, the latch device is held in the same manner as the latched state, that is, movable. A state in which the body is held at a fixed position of the main body can be obtained without impairing the push operation of the latch device.

And is locked in the locking groove of c. The lock is released by the next push operation, that is, the pin 35 traces c and d in the direction of the arrow and finally passes through e to leave the cam groove 30, whereby the movable body is fixed by the biasing force. Can be switched out of position.

That is, in the latch device 3, the inertia force acts in the same manner as the next push operation, and the pin 35 comes out of the locking groove portion of c and moves in the releasing direction of d. 4 is regulated. That is, when the safety device 4 receives the same inertial force as described above, the pin 45 shifts from the reciprocating groove portion of f to the locking groove portion of h (via the guide groove portion of g) so that it cannot move back. The body 2 is held at the main body fixed position.

Abstract
Description
(ア)前記応動部材は、衝撃等の負荷を受けたとき付勢部材の付勢力に抗して回動して、前記ピンを前記循環カム溝の往復溝部から係止溝部へ移行可能にする構成である(好適態様1)。
(イ)前記応動部材は、衝撃等の負荷を受けたとき付勢部材の付勢力に抗して摺動して、前記ピンを前記循環カム溝の往復溝部から係止溝部へ移行可能にする構成である(好適態様2)
(エ)前記応動部材は、前記本体に保持部を介して摺動自在に支持されるとともに、前記保持部より突出している突出端側に前記ピンを配置している構成である(好適態様4)。
(オ)前記循環カム溝は、前記ピンを前記往復溝部から前記係止溝部に係止用誘導溝部を介して移行可能にするとともに、前記可動体に対するプッシュ操作により前記ピンを前記係止溝部から復帰用誘導溝部等を介して再び前記往復溝部に移行可能にする構成である(好適態様5)。
(エ)-1、この基本設定では、リッド2の閉位置において、ラインSに対し直角が最も小さい衝撃の入力(慣性力)にて、リッド2に開方向への最大の回転モーメントが加わる。また、ラインSは安全装置側応動部材41と平行に設定されているため、リッド回転機構と安全装置側応動部材の回転機構の回転モーメント最大方向は同一である。
(エ)-2、そして、リッド2は閉位置において、衝撃荷重が11.9Gまでは回転しない(これはばね部材25及びラッチ装置4Aの反力設定による)、それに対し、同方向からの衝撃荷重に対し、安全装置4Aの応動部材41は8G以上にて回転する。それにより、リッド2が開方向に回転する前に安全装置側の応動部材41が回転し、上記したピン45が往復溝部fから係止溝部hに係止しリッド2を閉位置に保つ。
(エ)-3、衝撃入力範囲として、図3のAの場合はリッド2が無理抜き方向に回転するため開方向へ切り換えられない。衝撃入力範囲として、同図のBの場合は下から上向きに加わる下突(符号C)を例にすると、リッド2に加わる衝撃は同図の角度θによって、回転モーメントへの分力となる。同様に、安全装置4Aへの衝撃入力も回転モーメント方向への分力となるが、リッド2と安全装置側応動部材41の回転モーメント最大方向は同一方向であるため、前記分力の角度θも同一である。よって、(安全装置側応動部材41の回転開始>リッド2の回転開始)の関係は同図のBの範囲すべてで変わらない。以上より、リッド2は360度のどの方向からの衝撃入力(慣性力)に対しても開かないことになる。
なお、2007年12月26日に出願された日本国特許出願第2007-333611号の明細書、特許請求の範囲、図面及び要約書の全内容をここに引用し、本発明の明細書の開示として、取り入れるものである。
