Description
本発明は開き戸、引き出し等（以下これらを扉等という）を地震時に自動ロックする扉等の地震時ロック方法及び該方法を用いた地震対策付き棚に関するものである。The present invention relates to an earthquake locking method such as a door for automatically locking hinged doors, drawers and the like (hereinafter referred to as doors) and the like, and a shelf with an earthquake countermeasure using the method.
従来において地震時に扉等を自動ロックする地震時ロック装置においてはゆれによって球が動くことにより地震を検出する地震時ロック方法が用いられている。この場合において係止体は扉等の戻る動きにより解除されていたため解除機構が複雑になっていた。2. Description of the Related Art Conventionally, an earthquake locking device that automatically locks a door or the like in the event of an earthquake uses an earthquake locking method that detects an earthquake by moving a ball by shaking. In this case, since the locking body is released by the return movement of the door or the like, the release mechanism is complicated.
本発明は以上の従来の課題を解決し地震時に係止体が扉等の戻る動きとは独立し扉等の戻る動きで解除されず地震時に扉等の開く動きを許容しない状態を保持し、地震のゆれがなくなることにより扉等の戻る動きと関係なく前記係止体は扉等の開く動きを許容して動き可能な状態になる構成にすることにより解除機構を単純に出来る扉等の地震時ロック方法及び該方法を用いた地震対策付き棚の提供を目的とする。 The present invention solves the above-described conventional problems and maintains a state in which the locking body is not released by the return movement of the door or the like and is not released by the return movement of the door or the like during an earthquake and does not allow the movement of the door or the like to open during the earthquake, The seismic motion of the door, etc., can be made simple by making the locking body into a state in which it can move by allowing the movement of the door, etc., to open, regardless of the movement of the door, etc., by eliminating the shaking of the earthquake. An object is to provide a time locking method and a shelf with an earthquake countermeasure using the method.
本発明は以上の目的達成のために
地震時に扉等がばたつくロック状態となるロック方法において棚本体側に取り付けられた装置本体の係止体が地震時に扉等の開く動きを許容しない状態になり、前記係止体は扉等の戻る動きとは独立し扉等の戻る動きで解除されず地震時に扉等の開く動きを許容しない状態を保持し、地震のゆれがなくなることにより扉等の戻る動きと関係なく前記係止体は扉等の開く動きを許容して動き可能な状態になる扉等の地震時ロック方法等
を提案するものである。In order to achieve the above object, in the locking method in which the doors and the like flutter at the time of an earthquake, the locking body of the device main body attached to the shelf body side does not allow the doors and the like to open during the earthquake. The locking body is independent of the return movement of the door, etc., and is not released by the return movement of the door, etc., and does not allow the opening movement of the door, etc. in the event of an earthquake. The locking body proposes a method of locking an earthquake or the like of a door or the like that allows the locking body to move while allowing the opening of the door or the like regardless of the movement.
以下本発明の扉等の地震時ロック方法及び該方法を用いた地震対策付き棚を図面に示す実施例に従って説明する。
図１及び図２は本発明の参考例の地震時ロック方法を用いた扉等の地震時ロック装置を示し、該地震時ロック装置は装置本体（１）に振動エリアＡとしての凹所が設けられる。
該振動エリアＡの床面は図示の参考例では左右に傾斜が上がると共に前方にも傾斜が上がっている。
更に振動エリアＡには球（９）が振動可能に収納され該球（９）は振動エリアＡの中央後端をその安定位置にしている。
次に装置本体（１）には係止体（２）が軸（２ｃ）において回動可能に取り付けられる。該係止体（２）の軸（２ｃ）より前方である前部には前記振動エリアＡとしての開口が設けられ該開口において前記球（９）が収納される。
振動エリアＡとしての開口は図３に示す様に傾斜した前縁Ａ１において球（９）が前進する際に横方向の動きを付加可能にしている。
次に振動エリアＡとしての開口の前端にはその下面が傾斜した庇（２ｂ）が設けられる。Hereinafter, an earthquake locking method for a door and the like according to the present invention and a shelf with an earthquake countermeasure using the method will be described with reference to the embodiments shown in the drawings.
1 and 2 show an earthquake locking device such as a door using the earthquake locking method of a reference example of the present invention, and the earthquake locking device is provided with a recess as a vibration area A in the device main body (1). It is done.
In the illustrated reference example , the floor surface of the vibration area A is inclined to the left and right and is also inclined forward.
Further, a sphere (9) is housed in the vibration area A so as to vibrate, and the sphere (9) has the center rear end of the vibration area A at its stable position.
Next, the locking body (2) is attached to the apparatus body (1) so as to be rotatable about the shaft (2c). An opening as the vibration area A is provided in the front portion of the locking body (2) that is in front of the shaft (2c), and the sphere (9) is stored in the opening.
The opening as the vibration area A allows a lateral movement to be added when the sphere (9) moves forward at the inclined front edge A1 as shown in FIG.
Next, the front end of the opening as the vibration area A is provided with a ridge (2b) whose lower surface is inclined.
更に係止体（２）の先端には係止部（２ｅ）及び該係止部（２ｅ）に係止した係止具（５）（後述する）の係止部（５ａ）との係止保持力（係止解除力でもある）を確保する弾性部（２ｆ）が設けられる。
一方係止体（２）の後部には係止体（２）の重心を軸（２ｃ）に近付けてバランスを調整するための重り（２ｄ）が設けられる。
次に装置本体（１）からの係止体（２）の外れ防止のために装置本体（１）は蓋（３）でその上面を閉じられる。
以上の装置本体（１）は家具、吊り戸棚等の棚の本体（９０）にビス等で取り付けられる。
一方家具、吊り戸棚等の棚の開き戸（９１）（図示のものは引き出しを含む扉等の一例としての開き戸を示す）には係止具（５）がビス等で取り付けられる。
該係止具（５）は前記係止体（２）の係止部（２ｅ）に係止される係止部（５ａ）を有している。
以上の参考例に示した図１乃至図３の地震時ロック方法及びそれを用いた扉等の地震時ロック装置の作用は次の通り。
すなわち通常の使用状態においては図１に示す様に係止体（２）はその軸（２ｃ）を中心に前端の係止部（２ｅ）が下降した状態で安定している。
この状態において球（９）は装置本体（１）の振動エリアＡの傾斜面により形成された安定位置である中央後端又は後端近くに位置している。Further, at the tip of the locking body (2), the locking portion (2e) and the locking portion (5a) of the locking device (5) (described later) locked to the locking portion (2e) are locked. An elastic portion (2f) that secures a holding force (also an unlocking force) is provided.
On the other hand, a weight (2d) for adjusting the balance by bringing the center of gravity of the locking body (2) closer to the shaft (2c) is provided at the rear part of the locking body (2).
Next, the upper surface of the apparatus main body (1) is closed with a lid (3) in order to prevent the locking body (2) from coming off from the apparatus main body (1).
The apparatus main body (1) is attached to a main body (90) of a shelf such as furniture and a hanging cupboard with screws or the like.
On the other hand, a latch (5) is attached with a screw or the like to a hinged door (91) of a shelf such as furniture and a hanging cabinet (the illustrated one shows a hinged door as an example of a door including a drawer).
The locking tool (5) has a locking portion (5a) locked to the locking portion (2e) of the locking body (2).
The operation of the earthquake locking method of FIGS. 1 to 3 shown in the above reference example and the earthquake locking device such as a door using the method is as follows.
That is, in a normal use state, as shown in FIG. 1, the locking body (2) is stable with the locking portion (2e) at the front end lowered around the shaft (2c).
In this state, the sphere (9) is located at the center rear end or near the rear end, which is a stable position formed by the inclined surface of the vibration area A of the apparatus main body (1).
すなわち後端近くと言ったのは係止体（２）の振動エリアＡとしての開口により押された状態で球（９）が安定してもよいからである。
この安定位置にある安定状態において開き戸（９１）は開閉されるが係止体（２）の前端の係止部（２ｅ）が下降しているため係止具（５）は前記係止体（２）の係止部（２ｅ）に係止しない。
従って開き戸（９１）は自由に開閉され使用者は棚内部への物品の収納及び内部からの取り出しが可能になっている。
次に地震時においては棚の本体（９０）がゆれるため前方へのゆれの際には球（９）は振動エリアＡの中央後端又は後端近くの安定位置から図３に示す様に前進する。
その結果球（９）は係止体（２）の庇（２ｂ）を押し上げて係止体（２）の前端の係止部（２ｅ）は図４に示す様に上昇する。
ここで庇（２ｂ）がなかったとしても球（９）は係止体（２）の振動エリアＡの前端に当たるため係止体（２）の前端の係止部（２ｅ）は上昇する。
但し庇（２ｂ）があれば係止体（２）の前端の係止部（２ｅ）の上昇はより容易になっている。
ここで単に球（９）が直線的に振動する場合には地震の振動波形とほぼ同期して球（９）は振動する。
ところが開き戸（９１）は慣性が大きいためその開閉波形は地震の振動波形よりずれる（遅れる）。That is, it is said that it is near the rear end because the sphere (9) may be stabilized while being pushed by the opening as the vibration area A of the locking body (2).
In the stable state at the stable position, the hinged door (91) is opened and closed, but the locking part (2e) at the front end of the locking body (2) is lowered, so that the locking tool (5) is the locking body ( It is not locked to the locking part (2e) of 2).
Therefore, the hinged door (91) can be freely opened and closed, and the user can store and take out articles from the inside of the shelf.
Next, since the main body (90) of the shelf is shaken during an earthquake, the ball (9) moves forward from a stable position near the center rear end or the rear end of the vibration area A as shown in FIG. To do.
As a result, the ball (9) pushes up the hook (2b) of the locking body (2), and the locking portion (2e) at the front end of the locking body (2) rises as shown in FIG.
Even if there is no hook (2b), the ball (9) hits the front end of the vibration area A of the locking body (2), so that the locking portion (2e) at the front end of the locking body (2) rises.
However, if there is a hook (2b), the locking portion (2e) at the front end of the locking body (2) can be easily lifted.
Here, when the sphere (9) simply vibrates linearly, the sphere (9) vibrates substantially in synchronization with the vibration waveform of the earthquake.
However, the hinged door (91) has a large inertia, so its opening / closing waveform deviates (delays) from the vibration waveform of the earthquake.
すなわち地震のゆれの方向が前進方向から後退方向に逆転しても開き戸（９１）は慣性でそのまま開く方向の動きを継続する。
従って単に球（９）を直線的に振動させる従来の方法では地震の振動波形とほぼ同期して球（９）が後退するため係止体（２）の係止部（２ｅ）は下降し始めて係止具（５）の係止部（５ａ）は前記係止体（２）の係止部（２ｅ）に係止出来ずに開き戸（９１）は開いてしまう。
ところが図示の参考例においては係止体（２）に傾斜した前縁Ａ１を有する振動エリアＡを設け該振動エリアＡに収納された球（９）は前進する際に前記前縁Ａ１で横方向の動きが付加される。
その結果球（９）の前進経路（係止体（２）の振動エリアＡの広義の前縁Ａ１に沿った経路）と後退経路（係止体（２）の振動エリアＡの広義の後縁に沿った経路）を明確に異ならせることが可能になり後退経路において球（９）にかかる荷重を大きくすることが容易になり前進より後退の時間を長くすることが可能になっている。
この結果地震のゆれの方向が前進方向から後退方向に逆転しても係止体（２）の係止部（２ｅ）は上昇したままの状態をしばらく継続した後に下降する。
この係止部（２ｅ）が上昇したままの状態をしばらく継続することは非常に重要であってそれが開き戸（９１）の開く方向の動きの継続に対応するものになるのである。That is, even if the direction of the shaking of the earthquake is reversed from the forward direction to the backward direction, the hinged door (91) continues to move in the direction of opening as it is due to inertia.
Therefore, in the conventional method in which the sphere (9) is simply vibrated linearly, the sphere (9) moves backward almost in synchronization with the vibration waveform of the earthquake, so that the locking portion (2e) of the locking body (2) begins to descend. The locking part (5a) of the locking tool (5) cannot be locked to the locking part (2e) of the locking body (2), and the hinged door (91) opens.
However, in the illustrated reference example , the engaging body (2) is provided with a vibration area A having an inclined front edge A1, and the ball (9) housed in the vibration area A is moved laterally at the front edge A1 when moving forward. Movement is added.
As a result, the forward path of the ball (9) (the path along the broad front edge A1 of the vibration area A of the locking body (2)) and the backward path (the wide rear edge of the vibration area A of the locking body (2)). The path along the path) can be clearly different, and it is easy to increase the load applied to the ball (9) in the retreat path, and the retreat time can be made longer than the advance.
As a result, even if the direction of the shaking of the earthquake is reversed from the forward direction to the backward direction, the locking portion (2e) of the locking body (2) continues to remain in the raised state for a while and then descends.
It is very important to continue the state in which the locking portion (2e) is raised for a while, and this corresponds to the continuation of the movement of the hinged door (91) in the opening direction.
従って開き戸（９１）の開く方向の動きにより係止具（５）の係止部（５ａ）は前記係止体（２）の係止部（２ｅ）に係止することが出来る。
以上で明らかな通り後退経路において球（９）にかかる荷重を大きくし前進より後退の時間を長くしていることで開き戸（９１）の開閉波形のずれ（遅れ）に対応出来るのである。
後退経路において球（９）にかかる荷重を大きくする方法として図示の参考例では後退経路において球（９）を係止体（２）の軸（２ｃ）に近い部分に接触させ係止体（２）の重量による大きな荷重を作用させる一方前進経路においては球（９）を係止体（２）の軸（２ｃ）から遠い部分に接触させ係止体（２）の重量による小さな荷重を作用させているのである。
以上の結果後退する際に球（９）にかかる荷重が大きくなり前進より後退の時間が長くなるのである。
更に図示の参考例においては次の方法も付加して開き戸（９１）の開閉波形が地震の振動波形よりずれる（遅れる）ことに対応している。
すなわち棚本体側に取り付けられた装置本体（１）の振動エリアＡに球（９）を振動可能に収納し、該球（９）の前進経路と後退経路を異ならせ後退経路において開き戸（９１）の係止具（５）に係止する係止体（２）に接触させながら前記球（９）を後退させ球（９）による係止体（２）の持ち上げを可能にしている。Therefore, the locking part (5a) of the locking tool (5) can be locked to the locking part (2e) of the locking body (2) by the movement in the opening direction of the hinged door (91).
As apparent from the above, by increasing the load applied to the ball (9) in the backward path and making the backward time longer than the forward direction, it is possible to cope with the deviation (delay) of the open / close waveform of the hinged door (91).
As a method of increasing the load applied to the ball (9) in the backward path, in the illustrated reference example , the ball (9) is brought into contact with a portion close to the axis (2c) of the locking body (2) in the backward path. In the forward path, the ball (9) is brought into contact with a portion far from the axis (2c) of the locking body (2) to apply a small load due to the weight of the locking body (2). -ing
As a result, the load applied to the ball (9) when retreating increases, and the retreat time becomes longer than the advance.
Further, in the illustrated reference example , the following method is added to cope with the fact that the opening / closing waveform of the hinged door (91) is deviated (delayed) from the vibration waveform of the earthquake.
That is, the ball (9) is housed in the vibration area A of the apparatus main body (1) attached to the shelf main body so as to be able to vibrate, and the forward path and the backward path of the ball (9) are different from each other, and the swing door (91) The ball (9) is retracted while being brought into contact with the locking body (2) locked to the locking tool (5), thereby allowing the locking body (2) to be lifted by the ball (9).
更に棚本体側に取り付けられた装置本体（１）の振動エリアＡに球（９）を振動可能に収納し、該球（９）の前進経路と後退経路が同一の場合と異なる場合のいずれの場合（図示のものは異なる場合）においても開き戸（９１）の係止具（５）に係止する係止体（２）の軸（２ｃ）に近い部分に後退時において球（９）を接触させている。
この様にすれば球（９）による係止体（２）の持ち上げが大きくなり球（９）が後端に到るまで係止体（２）を持ち上げておき最後に係止体（２）を下降させることが容易になる。
更に図示されていないが棚本体側に取り付けられた装置本体（１）の振動エリアＡに球（９）を振動可能に収納し、該球（９）の前進経路と後退経路が同一の場合と異なる場合のいずれの場合（図示のものは異なる場合）においても球（９）の前進時と後退時の開き戸（９１）の係止具（５）に係止する係止体（２）への接触部分を異ならせ後退時における接触部分の摩擦を大きくしてもよい。
例えば後退時における接触部分の材料を摩擦の大きい材料にしたり表面をざらざらにしたりする方法がある。
更に図示の参考例においては棚本体側に取り付けられた装置本体（１）の振動エリアＡに球（９）を振動可能に収納し、該球（９）の前進経路と後退経路が同一の場合と異なる場合のいずれの場合（図示のものは異なる場合）においても開き戸（９１）の係止具（５）に係止する係止体（２）にゆれの戻り力を作用させながら（ゆれの戻り力により持ち上げながら）前記球（９）を後退させている。Furthermore, the ball (9) is housed in the vibration area A of the apparatus main body (1) attached to the shelf main body so as to vibrate, and the forward path and the backward path of the ball (9) are the same or different. Even in the case (the case shown in the figure is different), the ball (9) is brought into contact with the portion close to the shaft (2c) of the locking body (2) locked to the locking tool (5) of the hinged door (91) when retreating. I am letting.
In this way, the locking body (2) is lifted up by the ball (9), and the locking body (2) is lifted until the ball (9) reaches the rear end, and finally the locking body (2). Can be lowered easily.
Although not shown in the drawing, the ball (9) is housed in the vibration area A of the apparatus body (1) attached to the shelf body side so as to be able to vibrate, and the forward path and the backward path of the ball (9) are the same. In any case where the balls (9) are different (if they are different), the locking body (2) to be locked to the locking tool (5) of the hinged door (91) when the ball (9) moves forward and backward The contact portion may be made different to increase the friction of the contact portion during retraction.
For example, there is a method in which the material of the contact portion at the time of retraction is made of a material with high friction or the surface is rough.
Furthermore, in the illustrated reference example , the ball (9) is housed in the vibration area A of the apparatus main body (1) attached to the shelf main body side so as to vibrate, and the forward path and the backward path of the ball (9) are the same. In any case (if the figures are different), the swinging return force is applied to the locking body (2) locked to the locking tool (5) of the hinged door (91). The ball (9) is retracted while being lifted by a return force.
すなわち単に前進より球（９）の後退の時間を長くする消極的な方法でなく積極的にゆれの戻り力により係止体（２）を持ち上げるのである。
更に棚本体側に取り付けられた装置本体（１）の振動エリアＡに球（９）を振動可能に収納し、該球（９）の前進経路と後退経路が同一の場合と異なる場合のいずれの場合においても球（９）の経路として振動エリアＡの前部の経路を後部の経路より長くして球（９）が前部に存在する時間を後部に存在する時間より長くする地震時ロック方法もあり次の図６乃至図１１の参考例にこれを示す。
以上で明らかな通り上昇した状態を継続している係止体（２）の係止部（２ｅ）は開く方向の動きを継続する開き戸（９１）の係止具（５）の係止部（５ａ）に係止し開き戸（９１）は隙間を有してロックされる（図４から図５に到るのである）。
開き戸（９１）は地震のゆれの戻りの際に開き戸（９１）の重量と地震の加速度に応じて係止を外そうとする力を係止部（２ｅ）（５ａ）に作用する。
この係止を外そうとする力が係止体（２）の係止部（２ｅ）の近くに設けられた弾性部（２ｆ）の弾性抵抗（係止保持力）（係止解除力でもある）以下であれば係止状態は保持される。
すなわち開き戸（９１）の重量と予想される地震の加速度の両者から係止部（２ｅ）（５ａ）の（係止保持力）（係止解除力でもある）を設定しておくことにより予想される範囲の地震においては地震が終了するまで係止状態が保持される。That is, the locking body (2) is positively lifted not by a passive method of extending the retreat time of the ball (9) but by a swinging return force.
Furthermore, the ball (9) is housed in the vibration area A of the apparatus main body (1) attached to the shelf main body so as to vibrate, and the forward path and the backward path of the ball (9) are the same or different. Even in such a case, as the path of the sphere (9), the front path of the vibration area A is longer than the rear path, and the time during which the sphere (9) is present at the front is longer than the time at the rear. This is shown in the following reference examples of FIGS.
As described above, the locking portion (2e) of the locking body (2) that continues to rise is the locking portion (5) of the locking tool (5) of the hinged door (91) that continues to move in the opening direction. 5a) and the hinged door (91) is locked with a gap (from FIG. 4 to FIG. 5).
The hinged door (91) acts on the latching portions (2e) and (5a) with a force for releasing the latching according to the weight of the hinged door (91) and the acceleration of the earthquake when the shaking of the earthquake returns.
The force for releasing the locking is also the elastic resistance (locking holding force) (locking releasing force) of the elastic portion (2f) provided near the locking portion (2e) of the locking body (2). ) The locked state is maintained if it is below.
That is, it is expected by setting the (locking holding force) (also locking release force) of the locking portions (2e) and (5a) from both the weight of the hinged door (91) and the expected earthquake acceleration. In the range of earthquakes, the locked state is maintained until the earthquake ends.
地震が終わると使用者は隙間を有してロックされている図５の開き戸（９１）を係止保持力以上の力で押す。
これにより係止状態が解除され図５の状態から図１に示す様に係止体（２）の係止部（２ｅ）は下降し開き戸（９１）の開閉は自由になる。
ここで球（９）については地震が終わると係止状態の解除と関係なく装置本体（１）の振動エリアＡの床面の傾斜により中央後端の安定位置に戻る。
以上で明らかな通り図１乃至図５の扉等の地震時ロック方法は棚の本体（９０）側に取り付けられた装置本体（１）の係止体（２）が地震時に扉等の開く動きを停止させる位置であるロック位置へと動き、前記係止体（２）は扉等の戻る動きとは独立して動くことにより扉等の戻る動きで解除されず地震時にロック位置に到って振動し又はロック位置を保持し、地震のゆれがなくなることにより扉等の戻る動きと関係なく前記係止体（２）は待機位置へと戻る扉等の地震時ロック方法である。
そして図示のものは地震時に装置本体（１）の係止体（２）が扉等の係止具（５）に係止し扉等のばたつきのほとんどないロック状態となる扉等の地震時ロック方法であった。
図６乃至図１１は本発明（但し図１８及び図１９と異なる構成部分は本発明の範囲から除 く）の扉等の地震時ロック方法及び該方法を用いた地震対策付き棚である。When the earthquake is over, the user pushes the hinged door (91) of FIG.
As a result, the locked state is released, and the locking portion (2e) of the locking body (2) is lowered from the state of FIG. 5 to open and close the hinged door (91) as shown in FIG.
Here, when the earthquake ends, the ball (9) returns to the stable position at the center rear end due to the inclination of the floor surface of the vibration area A of the apparatus body (1) regardless of the release of the locked state.
As is apparent from the above, the locking method in the event of an earthquake such as the doors in FIGS. 1 to 5 is such that the locking body (2) of the device body (1) attached to the shelf body (90) side opens the doors and the like in the event of an earthquake. The locking body (2) moves independently of the return movement of the door, etc., and is not released by the return movement of the door, etc., and reaches the lock position in the event of an earthquake. The locking body (2) is a locking method during an earthquake such as a door returning to a standby position regardless of the movement of the door or the like returning by oscillating or holding the lock position and eliminating the shaking of the earthquake.
In the illustrated case, the locking body (1) of the device main body (1) is locked to the locking tool (5) such as a door in the event of an earthquake, and the door or the like is locked in a locked state with almost no flapping. Was the way.
6 to 11 present invention (different components except 18 and 19 except rather from the scope of the present invention) is a Earthquake with shelves with seismic lock method and process of the door or the like.
すなわち図６及び図７は本発明（但し図１８及び図１９と異なる構成部分は本発明の範囲 から除く）の地震時ロック方法を用いた扉等の地震時ロック装置を示し、該地震時ロック装置は装置本体（１）に振動エリアＡとしての凹所が設けられる。該振動エリアＡは球（９）が振動可能に収納され該振動エリアＡは図９に示す様に後端室Ａ９を有している。
更に振動エリアＡの前縁Ａ１は収納された球（９）が前進する際に横方向の動きを付加可能にしている。
振動エリアＡの床面は後端室Ａ９が最も低くそこからすりばち状にゆるやかに傾斜しているため球（９）の安定位置は後端室Ａ９である。
次に装置本体（１）には係止体（６）が軸（６ｅ）において回動可能に取り付けられる。該係止体（６）は図８に示す様に前部（６ａ）と後部（６ｆ）を有し該後部（６ｆ）は前記振動エリアＡの前部の上方に突き出している。
前部（６ａ）には屈曲して係止部（６ｂ）が設けられ開き戸（９１）に取り付けられた係止具（７）に係止可能にされる。
係止体（６）の係止部（６ｂ）は段（６ｃ）を有すると共に係止部先端（６ｄ）は両側に横幅が拡大されている。
次に係止具（７）は開口（７ａ）を有し該開口（７ａ）は係止体（６）の係止部（６ｂ）が嵌入されるものである。That is, FIGS. 6 and 7 show an earthquake locking device such as a door using the earthquake locking method of the present invention (except for the components different from FIGS. 18 and 19 from the scope of the present invention ). The apparatus is provided with a recess as a vibration area A in the apparatus main body (1). The vibration area A is housed so that the ball (9) can vibrate, and the vibration area A has a rear end chamber A9 as shown in FIG.
Further, the front edge A1 of the vibration area A allows a lateral movement to be added when the stored ball (9) moves forward.
The floor surface of the vibration area A is the rear end chamber A9 is the lowest, and since it is gently sloping from there, the stable position of the sphere (9) is the rear end chamber A9.
Next, a locking body (6) is attached to the apparatus main body (1) so as to be rotatable about a shaft (6e). As shown in FIG. 8, the locking body (6) has a front part (6a) and a rear part (6f), and the rear part (6f) protrudes above the front part of the vibration area A.
The front portion (6a) is bent to be provided with a locking portion (6b), and can be locked to a locking tool (7) attached to the hinged door (91).
The locking part (6b) of the locking body (6) has a step (6c), and the locking part tip (6d) is widened on both sides.
Next, the locking tool (7) has an opening (7a) into which the locking portion (6b) of the locking body (6) is inserted.
すなわち開口（７ａ）は係止具（７）の先端の開口端（７ｂ）へと連続し両者の間に距離の狭い絞り（７ｃ）が設けられる。
以上の実施例に示した図６乃至図９の地震時ロック方法及びそれを用いた扉等の地震時ロック装置の作用は次の通り。
すなわち通常の使用状態においては図６及び図７に示す様に係止体（６）はその軸（６ｅ）を中心に前部（６ａ）が自重で下降した状態になっている。
開き戸（９１）はこの状態で開閉されるが係止体（６）の係止部（６ｂ）の前面は係斜しているため係止具（７）が進入し当たると軸（６ｅ）を中心として係止体（６）の係止部（６ｂ）は上昇する。
従って係止具（７）は係止部（６ｂ）を持ち上げて進入し係止部（６ｂ）は係止具（７）の開口（７ａ）に嵌入する。
ここで進入過程において開口（７ａ）より先端側にある開口端（７ｂ）を係止体（６）の係止部先端（６ｄ）は通過する。
開口端（７ｂ）の開口幅は係止部先端（６ｄ）の横幅よりも狭くされているので係止部先端（６ｄ）は開口端（７ｂ）に嵌入することなく通過することが出来る。以上の係止体（６）の係止部（６ｂ）が持ち上げ可能であるのは振動エリアＡにおいて球（９）が後端室Ａ９の安定位置にあるからである。
すなわち係止体（６）の後部（６ｆ）は振動エリアＡの前部に位置しているため係止体（６）は球（９）に妨げられることなく回動することが出来るのである。In other words, the opening (7a) continues to the opening end (7b) at the tip of the locking tool (7), and a narrow aperture (7c) is provided between them.
The operation of the earthquake locking method of FIGS. 6 to 9 shown in the above embodiment and the earthquake locking device such as a door using the method is as follows.
That is, in a normal use state, as shown in FIGS. 6 and 7, the locking body (6) is in a state where the front part (6a) is lowered by its own weight with its axis (6e) as the center.
The hinged door (91) is opened and closed in this state, but the front surface of the locking portion (6b) of the locking body (6) is slanted, so that when the locking tool (7) approaches, the shaft (6e) is moved. As a center, the locking portion (6b) of the locking body (6) rises.
Accordingly, the locking tool (7) lifts the locking part (6b) and enters, and the locking part (6b) is fitted into the opening (7a) of the locking tool (7).
Here, in the entering process, the locking portion tip (6d) of the locking body (6) passes through the opening end (7b) located on the tip side of the opening (7a).
Since the opening width of the opening end (7b) is narrower than the lateral width of the locking portion tip (6d), the locking portion tip (6d) can pass through without being fitted into the opening end (7b). The reason why the locking portion (6b) of the locking body (6) can be lifted is that the ball (9) is in the stable position of the rear end chamber A9 in the vibration area A.
That is, since the rear portion (6f) of the locking body (6) is located at the front portion of the vibration area A, the locking body (6) can rotate without being obstructed by the ball (9).
以上は開き戸（９１）を閉じる際の係止体（６）の動きであったが開き戸（９１）を開く際には開口（７ａ）に嵌入している係止体（６）の係止部（６ｂ）は係止具（７）の開口（７ａ）の先端側の内壁（絞り（７ｃ）を形成している）に当たる。
軸（６ｅ）の位置より係止部（６ｂ）は下方であるため係止具（７）の後退に伴って係止体（６）の係止部（６ｂ）は開口（７ａ）の先端側の内壁によりやはり持ち上げられる。従って開き戸（９１）の開閉時に係止体（６）の係止部（６ｂ）は係止具（７）の開口（７ａ）に軽い力で嵌入と浮上をし開き戸（９１）の開閉の妨げ乃至大きな抵抗とはならない。
すなわち開き戸（９１）が閉じられた状態では係止体（６）の係止部（６ｂ）は図６及び図７に示す様に係止具（７）の開口（７ａ）に嵌入した状態になっている。
この状態で地震が起こると球（９）は振動エリアＡの図９に示す後端室Ａ９の安定位置から前進し前縁Ａ１において横方向に移動する。
振動エリアＡはその後部が後端室Ａ９でありその前部は傾斜した前縁Ａ１において側方に拡大している。
従って球（９）は前進すると傾斜した前縁Ａ１において横方向の動きが付加されることになる。The above is the movement of the latching body (6) when closing the hinged door (91), but when the hinged door (91) is opened, the latching part of the latching body (6) fitted in the opening (7a) (6b) corresponds to the inner wall (forming the aperture (7c)) on the tip side of the opening (7a) of the locking tool (7).
Since the locking portion (6b) is located below the position of the shaft (6e), the locking portion (6b) of the locking body (6) moves to the tip side of the opening (7a) as the locking tool (7) moves backward. It is still lifted by the inner wall. Therefore, when the hinged door (91) is opened and closed, the latching portion (6b) of the latching body (6) fits and floats with a slight force on the opening (7a) of the latching tool (7) and prevents the hinged door (91) from opening and closing. It is not a big resistance.
That is, when the hinged door (91) is closed, the locking portion (6b) of the locking body (6) is fitted into the opening (7a) of the locking tool (7) as shown in FIGS. It has become.
When an earthquake occurs in this state, the ball (9) advances from the stable position of the rear end chamber A9 shown in FIG. 9 in the vibration area A and moves laterally at the front edge A1.
The rear part of the vibration area A is the rear end chamber A9, and the front part is expanded laterally at the inclined front edge A1.
Accordingly, when the sphere (9) moves forward, a lateral movement is added at the inclined front edge A1.
従って球（９）は側方に拡大した前部内へと横方向に進む（その際前後振動を伴う場合もある）。
つまり球（９）の前進経路と後退経路が同一の場合と異なる場合のいずれの場合（図示の実施例においては異なる場合に該当）においても球（９）の経路として振動エリアＡの前部の経路を後部の経路より長くして（例えば前部の経路を側方に拡大して）球（９）が前部に存在する時間を後部に存在する時間より長くしているのである。
球（９）は前部内を横方向に進むが側端に到れば振動エリアＡの床面の傾斜により戻り始める。
球（９）は中央まで戻って後端室Ａ９に入る場合もあれば通り過ぎて反対側の側方に拡大した前部内へと進む場合もある。
すなわち球（９）が前部に存在する時間は後部に存在する時間より長くなり地震の振動波形からの開き戸（９１）の開閉波形のずれ（遅れ）に対応出来るのである。
すなわち開き戸（９１）が開く方向への動きを継続しても球（９）は係止体（６）の後部（６ｆ）の下方に位置したままである。
その結果図１０及び図１１に示す様に係止体（６）の係止部（６ｂ）は開き戸（９１）が開く方向への動きに伴って開口（７ａ）の先端側の内壁へと動きこれに当たっても持ち上げられない。Accordingly, the sphere (9) advances laterally into the front part expanded laterally (sometimes accompanied by longitudinal vibration).
That is, in both cases where the forward path and the backward path of the sphere (9) are the same and different (corresponding to different cases in the illustrated embodiment), the path of the sphere (9) is the front of the vibration area A. By making the path longer than the rear path (for example, by enlarging the front path to the side), the time for the sphere (9) to exist at the front is made longer than the time at the rear.
The sphere (9) proceeds laterally in the front, but when it reaches the side end, it begins to return due to the inclination of the floor surface of the vibration area A.
The sphere (9) may return to the center and enter the rear end chamber A9, or may pass through and advance into the front part enlarged on the opposite side.
That is, the time during which the sphere (9) is present at the front is longer than the time at which the sphere (9) is present at the rear, and it is possible to cope with the deviation (delay) of the opening / closing waveform of the hinged door (91) from the vibration waveform of the earthquake.
That is, even if the hinged door (91) continues to move in the opening direction, the ball (9) remains positioned below the rear part (6f) of the locking body (6).
As a result, as shown in FIGS. 10 and 11, the locking portion (6b) of the locking body (6) moves to the inner wall on the distal end side of the opening (7a) as the hinged door (91) moves in the opening direction. Even if it hits this, it cannot be lifted.
その結果係止具（７）の絞り（７ｃ）を係止部（６ｂ）（溝を有するため溝が縮まって）は通過し開口端（７ｂ）に到ることになる。
開口端（７ｂ）において係止部（６ｂ）は段（６ｃ）で係止保持力（係止解除力でもある）が確保される。
すなわち段（６ｃ）における係止保持力（係止解除力でもある）以下であれば開き戸（９１）は地震のゆれの戻りから受ける力によっては解除されない。
すなわち開き戸（９１）が隙間を有した状態でロックされることは図１乃至図５の参考例のものと同様である。
地震が終わると使用者は隙間を有してロックされている図１０及び図１１の状態の開き戸（９１）を係止保持力以上の力で押す。
これにより係止状態が解除され図１０及び図１１の状態から図６及び図７に示す様に係止体（６）は係止具（７）の絞り（７ｃ）を通過し開口（７ａ）へと戻り開き戸（９１）の開閉は自由になる。
一方球（９）については地震が終わると係止状態の解除と関係なく振動エリアＡの床面の傾斜により後端室Ａ９に戻る。
以上で明らかな通り図６乃至図１１の扉等の地震時ロック方法は棚の本体（９０）側に取り付けられた装置本体（１）の係止体（６）が地震時に扉等の開く動きを許容しない状態になり、前記係止体（６）は扉等の戻る動きとは独立し扉等の戻る動きで解除されず地震時に扉等の開く動きを許容しない状態を保持し、地震のゆれがなくなることにより扉等の戻る動きと関係なく前記係止体（６）は扉等の開く動きを許容して動き可能な状態になる扉等の地震時ロック方法である。As a result, the locking part (6b) (the groove is contracted because it has a groove) passes through the restrictor (7c) of the locking tool (7) and reaches the open end (7b).
At the opening end (7b), the latching portion (6b) is secured at the step (6c) with a latching holding force (also a latch releasing force).
That is, the hinged door (91) is not released by the force received from the return of the shaking of the earthquake as long as it is below the locking holding force (also the locking release force) in the step (6c).
That is, it is the same as that of the reference example of FIG. 1 thru | or FIG. 5 that the hinged door (91) is locked in the state which has the clearance gap.
When the earthquake ends, the user pushes the hinged door (91) in the state shown in FIGS.
As a result, the locked state is released, and the locking body (6) passes through the aperture (7a) of the locking tool (7) as shown in FIGS. 6 and 7 from the state of FIGS. The door (91) can be opened and closed freely.
On the other hand, the sphere (9) returns to the rear end chamber A9 due to the inclination of the floor surface of the vibration area A regardless of the release of the locked state when the earthquake ends.
As is clear from the above, the locking method for earthquakes such as the doors of FIGS. 6 to 11 is the movement of the locking body (6) of the device main body (1) attached to the main body (90) side of the shelf to open the doors or the like in the event of an earthquake. The locking body (6) is independent of the return movement of the door, etc., and is not released by the return movement of the door, etc., and maintains the state where the movement of the door, etc. is not allowed in the event of an earthquake. The locking body (6) is a method for locking a door or the like in an earthquake that allows the door or the like to move and allows the door or the like to open, regardless of the movement of the door or the like returning due to the absence of shaking.
そして図示のものは地震時に装置本体（１）の係止体（６）が扉等の係止具（７）に係止し扉等のばたつきのほとんどないロック状態となる扉等の地震時ロック方法であった。
すなわち図１乃至図１１の扉等の地震時ロック方法に共通することは地震時に装置本体（１）の係止体（２）（６）が扉等の係止具（５）（７）に係止し扉等のばたつきのほとんどないロック状態となることであった。
以上の地震時ロック方法のいずれかに適用が可能な振動エリアＡの他の参考例（但しこれに限るものではない）を図１２乃至図１７に示す。
すなわち図１２の振動エリアＡは３角形状、図１３はＴ字状及び図１４はＹ字状である。図１５は後端室Ａ９が左右に２個あり両者を結ぶ振動エリアＡになっており図１６及び図１７の振動エリアＡは側方に拡大した前部が左右一方にのみ設けられたものである。In the illustrated case, the locking body (6) of the device main body (1) is locked to the locking tool (7) such as a door in the event of an earthquake, and the door or the like is locked in a locked state with almost no flapping. Was the way.
That is, what is common to the locking method in the event of an earthquake such as the door shown in FIGS. It was locked and there was almost no fluttering of the door.
Other reference examples (but not limited to) of the vibration area A that can be applied to any of the above-described earthquake locking methods are shown in FIGS.
That is, the vibration area A in FIG. 12 has a triangular shape, FIG. 13 has a T shape, and FIG. 14 has a Y shape. FIG. 15 is a vibration area A having two rear end chambers A9 on the left and right sides, and the vibration area A in FIGS. 16 and 17 is provided with a front portion expanded laterally only on one side. is there.
次に図１８及び図１９は本発明の扉等の地震時ロック方法の実施例であり、図６乃至図１１に示したものと比較し地震時に扉等がばたつくロック状態となる扉等の地震時ロック方法であることを特徴とする。
すなわち係止体（６）の係止部（６ｂ）は扉等の係止具（７）に係止することなく単に停止されるものであり地震時に扉等がばたつくロック状態となる。Next, FIG. 18 and FIG. 19 show an embodiment of the locking method for an earthquake of a door or the like according to the present invention, and the earthquake of a door or the like which is in a locked state where the door flutters in the event of an earthquake as compared with the one shown in FIGS. It is a time lock method.
That is, the locking part (6b) of the locking body (6) is simply stopped without being locked to the locking tool (7) such as a door, and the door or the like flutters during an earthquake.
次に図２０の参考例は図１乃至図５に示したものと比較し地震時に扉等がばたつくロック状態となる扉等の地震時ロック方法であることを特徴とする。
すなわち係止体（２）の係止部（２ｅ）は扉等の係止具（５）の係止部（５ａ）に係止することなく単に停止されるものであり地震時に扉等がばたつくロック状態となる。Next, the reference example of FIG. 20 is characterized in that it is a method of locking a door or the like in an earthquake that locks the door or the like in the event of an earthquake as compared with the one shown in FIGS.
That is, the locking portion (2e) of the locking body (2) is simply stopped without being locked to the locking portion (5a) of the locking tool (5) such as a door, and the door or the like flutters during an earthquake. It becomes locked.
本発明の扉等の地震時ロック方法及び該方法を用いた地震対策付き棚の実施例は以上の通りでありその効果を次に列記する。
本発明の地震時ロック方法は特に係止体が扉等の戻る動きとは独立し扉等の戻る動きで解除されず地震時に扉等の開く動きを許容しない状態を保持し、地震のゆれがなくなることにより扉等の戻る動きと関係なく前記係止体は扉等の開く動きを許容して動き可能な状態になる構成にすることにより解除機構を単純に出来る。The embodiment of the earthquake locking method for a door or the like and the shelf with an earthquake countermeasure using the method according to the present invention are as described above, and the effects thereof are listed below.
In the earthquake locking method of the present invention, in particular, the locking body is independent of the return movement of the door, etc., and is not released by the return movement of the door, etc. The release mechanism can be made simple by adopting a configuration in which the locking body is allowed to move by allowing the movement of the door or the like to open regardless of the movement of the door or the like to return.
