Description

本発明は家具等の収納装置の、開き扉や引き出しや引戸の戸体の、地震時の開放を阻止するための閉止装置に関するものである。   The present invention relates to a closing device for preventing an opening of a storage device such as furniture from being opened during an earthquake, and a door of a drawer or a sliding door.

従来の耐震用閉止装置は、主に家具等の収納装置の開き扉に対して地震時の開放を阻止し、収納物の落下を防ぐことを目的とされており、地震の揺れに呼応して転動する本体ケース内での転動体の動作により係止部分を有する係合体と受け部材を係合させて扉の開放を阻止する構成を基本としたものが特開平9−177412号公報等に多数開示されている。これらの構成では、設置枠体の内部上面に転動体を有する本体装置を取り付け、開閉移動体である回転扉の内側上部に受け装置を取り付ける配置が一般的である。   Conventional seismic closing devices are mainly intended to prevent the opening of storage devices such as furniture from being opened during an earthquake and to prevent the fall of stored items. Japanese Patent Application Laid-Open No. 9-177712 discloses a structure in which an engagement body having a locking portion and a receiving member are engaged to prevent the door from being opened by the operation of the rolling body within the rolling body case. Many have been disclosed. In these configurations, an arrangement in which a main body device having a rolling element is attached to an inner upper surface of an installation frame body and a receiving device is attached to an inner upper portion of a rotary door that is an open / close moving body is common.

ここで上記のように閉止装置を開き扉に装着するときは、収納物の出し入れに邪魔にならないようにすることが重要である。したがって全体をコンパクトにすることは当然のことであり、特に厚み方向を小さくすることが要求されてきている。ところが長期間使用するため、取り付け後に扉が垂れ下がったり、扉の反り等で本体部材と係合部材との係合位置が狂ってしまうことが考えられ、さらには取り付け段階での許容誤差も必要である。その結果係合可能範囲を広く取っておくことが不可欠になり、その分サイズ面では増大する傾向になり、上記でのコンパクト化とは相反することになりがちである。   Here, when the closing device is attached to the opening door as described above, it is important not to get in the way of storage and removal. Therefore, it is natural to make the whole compact, and in particular, it has been required to reduce the thickness direction. However, since it is used for a long time, the door may hang down after installation, or the engagement position between the main body member and the engagement member may be out of order due to warpage of the door, etc. Furthermore, an allowable error at the installation stage is also necessary. is there. As a result, it is indispensable to keep a wide engagement range, and accordingly, the size tends to increase, which tends to conflict with the above-described compacting.

また最近では開き扉のみでなく引き出しや引戸の戸体においても地震時の開放を阻止することが要求されるようになってきている。これらの場合は上記の扉に相当する開閉移動体が引き出し本体や戸体になり、設置枠体の側面若しくは天面に閉止装置の本体装置を、開閉移動体である引き出し本体や戸体に受け装置を装着する構成になる。また引き出しに閉止装置を装着する場合は、収納スペース側に出っ張った状態では収納物の出し入れの際に邪魔になるため、したがって引き出しの奥位置か、両サイドの引き出しレールと枠体側板との間、つまり引き出し外側面と枠体内側面との隙間部分か、もしくは引き出し本体の側板の上部位置程度に限られ、さらに取り付け可能なスペースが狭いと想定される。   Recently, not only the opening doors but also the drawers and sliding doors are required to be prevented from being opened during an earthquake. In these cases, the opening / closing moving body corresponding to the above door becomes the drawer body or door body, and the body device of the closing device is received by the drawer body or door body which is the opening / closing moving body on the side surface or top surface of the installation frame body. It becomes the composition which installs the device. In addition, when installing a closing device on the drawer, it is in the way of storage when the storage space protrudes to the storage space side. Therefore, either at the back of the drawer or between the drawer rails on both sides and the frame side plate In other words, it is limited to the gap portion between the outer surface of the drawer and the side surface of the frame or the upper position of the side plate of the drawer body, and the space that can be attached is assumed to be narrow.

そこで、枠体内側面を掘り込んで本体装置を埋め込んで装着し、引き出し外側面に受け装置を装着する構成が収納スペースを減少させない手段としては有効と想定される。しかし掘り込んで装着する場合は、当然掘り込みのための別途加工工程が必要になり、引き出しの両側に装着するとすれば1個の引き出しに左右2箇所掘り込みをすることになる。従って極力簡単な加工にて堀込みができる構成であることが望ましい。   Therefore, it is assumed that the configuration in which the main body device is embedded by digging the side surface inside the frame and the receiving device is mounted on the outer surface of the drawer is effective as a means for reducing the storage space. However, when digging and mounting, a separate processing step is naturally required for digging, and if it is mounted on both sides of the drawer, two left and right digs are made in one drawer. Therefore, it is desirable to have a configuration that enables excavation by as simple a process as possible.

また従来の閉止装置の多くは、地震による揺れが収束した段階でそのまま数秒放置すると自然に転動体が解除位置に復帰して閉止動作を自動的に解除するような機構や、若しくは閉止動作後に移動体が少しだけ開いて停止した状態からもう一度完全に閉めなおす動作により解除可能とする機構を既に有している。しかし収納装置自体が傾いてしまったり、閉止状態で予期せぬ衝撃や突発的な力がかかり内部構造が破損する等によりこの解除動作が機能しなくなる場合も考えられ、このような場合においても収納装置自体を破損させること無く開閉移動体を強制開放させることが最近では必要とされてきており、この強制的に閉止状態を解除できる機構をも備えているものはまだ少ない。特に引き出しに装着した場合においては装着するスペース自体が狭いのであるから、当然強制解除に関してもさらに狭い範囲にて実施しなければならないため非常に難しいと想定される。
特開平9−177412号公報
In addition, many of the conventional closing devices move after the closing operation, or the mechanism that the rolling element automatically returns to the release position and automatically releases the closing operation when the shaking due to the earthquake has converged for several seconds. It already has a mechanism that can be released by a complete reclosing operation from a state where the body is opened and stopped slightly. However, it is possible that the release operation may not work due to tilting of the storage device itself, or an unexpected impact or sudden force applied in the closed state, resulting in damage to the internal structure. Recently, it has been required to forcibly open the opening / closing moving body without damaging the device itself, and few of them are equipped with a mechanism capable of forcibly releasing the closed state. In particular, when it is attached to a drawer, the space itself to be attached is narrow, so it is naturally assumed that it is very difficult because forced release must be performed in a narrower range.
Japanese Patent Laid-Open No. 9-177412

そこで、地震の揺れを感知すると即座に係合状態になり、収束後にそのまま数秒放置することにより自然解除可能な構成を有しており、コンパクトな形態を維持し、かつ取り付け時の許容誤差や使用後に位置がずれた時にも対応できるような構成の閉止装置が望まれる。さらには収納装置自体が傾いたり、もしくは予期せぬ衝撃等で自然解除動作が作動しなくなっても、収納部材自体を破壊することなく別途の簡単な操作にて強制解除して開閉移動体を大きく開放でき、収納物を取り出せることも併せて要求される。
Therefore, it is immediately engaged when it detects an earthquake shake, and has a structure that can be released naturally by leaving it alone for several seconds after convergence, maintaining a compact form and allowing for tolerances and use during installation. A closing device configured to be able to cope with a later shift in position is desired. In addition, even if the storage device itself tilts or the natural release operation does not work due to unexpected impacts, etc., the storage member itself is forcibly released by a simple operation without destroying the storage member itself to enlarge the open / close moving body It is also required to be able to open and take out the stored items.

本発明は上記問題点を解決するためになされたものであり、本体ケース内に挿入された転動体が地震の揺れにより解除位置から移動した段階で即座に扉や引き出し等の開閉移動体の開放を阻止し、さらに開閉移動体の閉鎖最終段階にて本体装置の係止突起に対して受け装置の係合凸部が最適な位置に自動的に案内する機構を追加することで建付け誤差や収納物の重量によるたわみにも対処でき、収納物の出し入れを妨げないコンパクトな形態を維持し、かつ設置枠体の内側面に掘り込んだ状態でも装着可能であり、予期せぬ現象により閉止状態から解除できなくなった際にも強制的に開放可能な機構を有する新しい構成の地震時の閉止装置を提供することを目的とする。 The present invention has been made to solve the above-described problems, and when the rolling element inserted in the main body case moves from the release position due to the shaking of the earthquake, the opening / closing moving body such as a door or a drawer is immediately opened. In addition, in the final stage of closing of the opening / closing moving body, a mechanism for automatically guiding the engaging protrusion of the receiving device to the optimal position with respect to the locking protrusion of the main body device is added, so that an installation error or It can cope with deflection due to the weight of the stored item, maintains a compact shape that does not prevent the storage of the stored item, can be installed even when it is dug into the inner surface of the installation frame, and closes due to an unexpected phenomenon An object of the present invention is to provide an earthquake closing device having a new structure having a mechanism that can be forcibly opened even when it cannot be released.

本発明では上記問題点を解決するために次の技術手段を設けた。まずつば部分を有した箱状の本体ケースを設け、本体ケース内の下面に傾斜底面を形成し、さらに本体ケースの正面に2ヵ所の異型開口窓を開けておく。次に傾斜面と平坦面が連続して形成される昇降斜面と係止突起と案内溝を有した移動部材を設ける。そして球形状の転動体を本体ケースの傾斜底面に乗せた状態で挿入し、係止突起と昇降斜面が2ヵ所の開口窓から突出する配置で移動部材を本体ケースに組み込む。このとき本体ケースの手前側下部に係止突起が配置され、その奥に傾斜面に続いて平坦面が位置するように昇降斜面を配置し、昇降斜面は係止突起よりも上部位置になるように設定しておく。さらに案内凸部を有した本体フタを設け、移動部材の案内溝に嵌合させた状態で本体ケースに本体フタを被せて本体装置を構成する。   In the present invention, the following technical means are provided to solve the above problems. First, a box-shaped main body case having a collar portion is provided, an inclined bottom surface is formed on the lower surface of the main body case, and two variant opening windows are opened in front of the main body case. Next, a moving member having an ascending / descending slope formed by continuously forming an inclined surface and a flat surface, a locking projection, and a guide groove is provided. Then, the spherical rolling element is inserted in a state where it is placed on the inclined bottom surface of the main body case, and the moving member is incorporated into the main body case in such a manner that the locking projections and the elevation slope protrude from the two opening windows. At this time, the locking projection is arranged at the lower part on the near side of the main body case, and the up-and-down slope is arranged so that the flat surface is located behind the inclined surface, and the up-and-down slope is located above the locking projection. Set to. Further, a main body cover having a guide convex portion is provided, and the main body cover is covered with the main body case in a state where the main body cover is fitted in the guide groove of the moving member, thereby constituting the main body device.

このとき移動部材は本体ケース内で常に斜め上下方向に平行移動するように案内溝と案内凸部を配置しておく。そして移動部材の下面を下部幅広面として形成し、この下部幅広面を本体ケースの傾斜底面と同じ角度になるように設定しておく。つまり2ヵ所の開口窓はこの動作とともに本体ケース正面から突出している昇降斜面と係止突起が移動できるようにしたものである。また本体ケースの傾斜底面は奥側が低くなるように緩い傾斜を設けておく。すると通常時には転動体は本体ケースの奥側である傾斜底面の最も低い位置に停止した状態で保持される。そして、この状態で移動部材は本体ケースで最も下がった位置になるように設定しておき、移動部材の下部幅広面は転動体の頂点より遥かに下方に位置するように構成しておく。   At this time, the guide groove and the guide convex portion are arranged so that the moving member always translates obliquely up and down in the main body case. The lower surface of the moving member is formed as a lower wide surface, and the lower wide surface is set to have the same angle as the inclined bottom surface of the main body case. In other words, the two opening windows allow the up-and-down inclined surfaces and the locking projections protruding from the front of the main body case to move together with this operation. The inclined bottom surface of the main body case is provided with a gentle inclination so that the back side is lowered. Then, normally, the rolling element is held in a state of being stopped at the lowest position on the inclined bottom surface, which is the back side of the main body case. In this state, the moving member is set so as to be in the lowest position in the main body case, and the lower wide surface of the moving member is configured to be positioned far below the apex of the rolling element.

次に受けケ−スを設け、中央に軸心を有しその両側に係合凸部と強制解除用突起を備えたプロペラ形状の係合体を組み合わせて受け装置を構成する。このとき係合体は軸心を中心として受けケ−スに対して一定角度のみ回転移動可能なようにしておく。また通常の状態では軸心と係合凸部と強制解除用突起は水平方向に一直線に配置されており、強制解除用突起を押して係合体を回転させると係合凸部は当然逆方向に移動させることができる。ここで重要な点としては、この回転によるシーソー動作時に係合体と受けケ−スが摩擦を有した状態で移動するように設定しておき、押し引きする動作には所定以上の力が必要なようにしておく。   Next, a receiving case is provided, and a receiving device is configured by combining a propeller-shaped engaging body having an axial center in the center and engaging engaging portions and forcible releasing protrusions on both sides thereof. At this time, the engaging body is allowed to rotate and move by a fixed angle with respect to the receiving case with the shaft center as the center. Further, in a normal state, the shaft center, the engaging convex portion, and the forcible release protrusion are arranged in a straight line in the horizontal direction, and when the forcible release protrusion is pushed and the engaging body is rotated, the engaging convex portion naturally moves in the reverse direction. Can be made. The important point here is that the engaging body and the receiving case are set so as to move in a state of friction during the seesaw operation by the rotation, and the pushing and pulling operation requires a predetermined force or more. Keep it like that.

そして本体装置を設置枠体に、受け装置を開閉移動体に、本体装置の昇降斜面と係止突起が受け装置の係合凸部と面対する配置で装着する。ここで本体装置は手前から係止突起、昇降斜面の傾斜面、昇降斜面の平坦面の順になるように配置し、受け装置は手前から強制解除用突起、軸心、係合凸部の順に配置されるように構成する。そして本体装置と受け装置の上下方向の位置関係は、本体装置の係止突起の上端にかろうじて接触しない位置に受け装置の係合凸部が配置され、この係合凸部の位置が昇降斜面の傾斜面の上部と同一水平線上になるように設定する。また横方向の位置関係では、本体ケースと受けケース自体は接触せず、両方から向かい合う状態で突出している係合凸部と係止突起と昇降斜面の先端部分の一定範囲のみが当接するように構成しておく。   Then, the main body device is mounted on the installation frame body, the receiving device is mounted on the opening / closing moving body, and the ascending / descending slope and the locking projection of the main body device are mounted so as to face the engaging convex portion of the receiving device. Here, the main unit is arranged from the front in the order of the locking projection, the inclined surface of the elevating slope, and the flat surface of the elevating slope, and the receiving device is arranged from the front in the order of the forcible release projection, the shaft center, and the engaging convex part To be configured. The positional relationship in the vertical direction between the main body device and the receiving device is such that the engaging convex portion of the receiving device is arranged at a position where it hardly barely contacts the upper end of the locking projection of the main body device. Set to be on the same horizontal line as the upper part of the inclined surface. In addition, in the lateral positional relationship, the main body case and the receiving case itself do not come into contact with each other, so that only a certain range of the engaging convex portion, the locking projection, and the tip portion of the ascending / descending slope that protrude in a state of facing each other comes into contact. Make up.

次に、開閉移動体が大きく開放している状態から閉鎖させると、完全に閉鎖する直前に本体装置と受け装置が面対し、受け装置の係合凸部が本体装置の係止突起のすぐ上を通過して昇降斜面の傾斜面上部に当接する。すると係合凸部が移動部材を押し上げることになり、係合凸部の上端に昇降斜面の平坦面が乗る位置まで移動部材を持ち上げる動作が得られる。つまりこの状態が完全に開閉移動体が閉じているときの状態である。またこの閉鎖状態では移動部材とともに係止突起も持ち上がっており、このとき係止突起と係合凸部が水平になるように構成しておく。さらには移動部材の下部幅広面も同時に持ち上がっており、この閉鎖状態での下部幅広面と本体ケースの傾斜底面間の寸法が非常に重要で、移動部材の下部幅広面と傾斜底面は平行でかつその上下間の距離が転動体の直径より僅かにのみ大きくなるように設定しておく。   Next, when the opening / closing moving body is closed from a state where it is largely open, the main body device and the receiving device face each other immediately before the opening / closing moving body is completely closed, and the engaging convex portion of the receiving device is immediately above the locking projection of the main body device. And contact the upper part of the inclined surface of the rising and falling slope. Then, the engaging convex portion pushes up the moving member, and an operation of lifting the moving member to a position where the flat surface of the ascending / descending slope is on the upper end of the engaging convex portion is obtained. That is, this state is a state when the open / close moving body is completely closed. Further, in this closed state, the locking projection is lifted together with the moving member, and at this time, the locking projection and the engaging convex portion are configured to be horizontal. Furthermore, the lower wide surface of the moving member is also lifted at the same time, and the dimension between the lower wide surface and the inclined bottom surface of the main body case in this closed state is very important, and the lower wide surface and the inclined bottom surface of the moving member are parallel and The distance between the upper and lower sides is set to be slightly larger than the diameter of the rolling elements.

また閉鎖状態からの開放動作においては、開閉移動体が開く初期段階で本体装置の昇降斜面の平坦面上を受け装置の係合凸部が滑り、傾斜部分に差し掛かると傾斜に沿って移動部材が下方に自然落下移動することになる。そして係合凸部が傾斜部分の最上部位置にまでくると移動部材は最も下がった状態に戻り、この段階で既に移動部材の係止突起も同時に下がっているためそのまま開閉移動体は開放される動作になる。つまり傾斜部分に沿って係合凸部が移動することにより移動部材が上下運動を繰り返しながら開閉移動体が開閉することになり、通常の開閉移動体の開閉動作においては係合凸部と係止突起は当接しない。またこの動作中に移動部材は転動体と接触することは無く、転動体は解除位置に停止したままである。   Further, in the opening operation from the closed state, the engaging convex portion of the device slides on the flat surface of the ascending / descending slope of the main body device at the initial stage when the opening / closing moving body opens, and the moving member moves along the inclination when reaching the inclined portion. Will naturally fall down. When the engaging convex portion reaches the uppermost position of the inclined portion, the moving member returns to the lowest position, and at this stage, the locking projection of the moving member has already been lowered at the same time, so the opening / closing moving body is opened as it is. It becomes operation. In other words, when the engaging convex portion moves along the inclined portion, the movable member opens and closes while the moving member repeats up and down movements. In the normal opening and closing operation of the opening and closing movable member, the engaging convex portion is locked. The protrusion does not contact. Further, during this operation, the moving member does not come into contact with the rolling element, and the rolling element remains stopped at the release position.

ところが閉鎖状態で地震による揺れが発生すると、閉鎖状態での移動部材の下部幅広面と傾斜底面間は転動体の直径より僅かに広くなっているため、小さい揺れの段階で即座に転動体が本体ケース内で転動して解除位置からはずれる。そしてそのまま揺れが収束すると転動体は解除位置に自然復帰し、その後は通常と同じ開閉動作が可能になる。ところが強い揺れが発生して開閉移動体が開放すると、このときも転動体は当然解除位置から外れているため、移動部材が下方に下がろうとしても下部幅広面が転動体の頂点に乗った状態になり、移動部材の係止突起も下方に下がる動作を規制されることになる。その結果係合凸部が係止突起に係合して開閉移動体の開放を阻止することが可能になる。   However, when shaking occurs due to an earthquake in the closed state, the space between the lower wide surface and the inclined bottom surface of the moving member in the closed state is slightly wider than the diameter of the rolling element. It rolls in the case and deviates from the release position. When the shaking converges, the rolling element naturally returns to the release position, and after that, the same opening / closing operation can be performed. However, when a strong shaking occurs and the open / close moving body is released, the rolling element is naturally out of the release position at this time, so even if the moving member tries to move downward, the lower wide surface gets on the top of the rolling element. Thus, the movement of the locking projection of the moving member to be lowered is restricted. As a result, it becomes possible to prevent the opening / closing moving body from being opened by engaging the engaging protrusion with the locking protrusion.

この閉止動作においては、係合凸部が昇降斜面の平坦面位置からはずれて係止突起と係合するまでに僅かな移動距離を有し、したがってその距離分だけにおいては、開閉移動体は揺れの方向に従って細かく移動することになる。しかしその距離は非常に小さく、大きく開け放つような開放動作は確実に阻止することができる。そして地震による揺れが収まり、開閉移動体を閉鎖状態に戻すと転動体は傾斜底面により解除位置に自然復帰することになり、そのままで移動体の開放動作が再度可能になる。   In this closing operation, the engaging convex portion has a slight moving distance until it is disengaged from the flat surface position of the ascending / descending slope and engages with the locking projection. Therefore, only in this distance, the opening / closing moving body swings. It will move finely according to the direction. However, the distance is very small, and the opening operation that opens widely can be surely prevented. When the shaking due to the earthquake is settled and the open / close moving body is returned to the closed state, the rolling body spontaneously returns to the release position by the inclined bottom surface, and the moving body can be opened again as it is.

また大きく開放した状態で地震が発生した場合においても、そのまま閉鎖させると係合凸部が昇降斜面に当接する動作になり、下方に下がった状態の移動部材を持ち上げながら開閉移動体を閉鎖することが可能である。そして完全に閉鎖させた状態でもまだ引き続き地震による揺れが続いている場合は、上記と同様にその後の開閉移動体の開放を阻止する動作が得られることになる。   Also, even when an earthquake occurs in a largely open state, if it is closed as it is, the engaging convex part will come into contact with the ascending / descending slope, and the open / close moving body will be closed while lifting the moving member in the downward state Is possible. If the earthquake continues to shake even in the completely closed state, an operation for preventing the subsequent opening / closing moving body from being opened is obtained in the same manner as described above.

つまり本発明の基本機構としては、通常の開閉動作毎に移動部材を昇降させ、移動部材が持ち上がっている閉鎖状態で転動体が転動できるだけの空間を形成させるものであり、したがって適正な下部幅広面と傾斜底面間の距離を得るには本体装置と受け装置との上下の位置関係、特に昇降斜面に係合凸部が最初に当接する位置と、その後完全に閉鎖するまでに移動部材を持ち上げる距離が非常に重要である。   That is, the basic mechanism of the present invention is to raise and lower the moving member for each normal opening and closing operation so as to form a space that allows the rolling element to roll in the closed state in which the moving member is lifted. In order to obtain the distance between the surface and the inclined bottom surface, the upper and lower positional relationship between the main body device and the receiving device, in particular, the position where the engaging convex portion first contacts the lifting slope, and then lift the moving member until it is completely closed The distance is very important.

そこで本体ケースの前部に案内用テーパー面を設け、係止突起の上部にも案内用テーパー面を形成し、両者を向かい合った配置にしておく。そして受けケ−スに対して係合体が軸心を中心に一定の摩擦力を有した状態で一定の角度範囲のみ回転移動可能に構成しておく。すると本体装置と受け装置の上下位置に誤差が生じた場合においても、完全に閉鎖する直前に係合凸部が係止突起の案内用テーパー面と本体ケースの案内用テーパー面に当接し、本体装置に対する上下方向の基準位置に案内され、そのまま案内された位置を保持する動作が得られる。   Therefore, a guide taper surface is provided at the front portion of the main body case, and a guide taper surface is formed also on the upper portion of the locking projection, and the two are arranged facing each other. Then, the engaging body is configured to be able to rotate and move only within a certain angular range with respect to the receiving case in a state where the engaging body has a certain frictional force around the axis. Then, even when an error occurs in the vertical position of the main body device and the receiving device, the engaging convex portion comes into contact with the guiding taper surface of the locking protrusion and the guiding taper surface of the main body case immediately before completely closing, and the main body It is guided to a reference position in the vertical direction with respect to the apparatus, and an operation for maintaining the guided position as it is is obtained.

したがって次回からの開閉動作においては、係合凸部は本体ケースに対して常に基準位置にて出入りすることになり、この案内のための係合凸部と両案内用テーパー面との当接は初回のみである。また長期間の使用で万一開閉移動体の位置が狂った場合においても自動的に再度案内し直すことになり、常に基準位置での作動が可能になる。ここで両案内用テーパー面を通過した後に係合凸部は昇降斜面に当接して移動部材を持ち上げる動作になるのであるが、このときに係合凸部が動いては誤作動になるため、移動部材を持ち上げるのに必要な力より前述の摩擦力の方が遥かに大きくなるように設定しておく必要がある。   Therefore, in the next opening / closing operation, the engagement convex portion always enters and exits from the main body case at the reference position, and the contact between the engagement convex portion for this guide and both guide tapered surfaces is Only the first time. In addition, even if the position of the opening / closing moving body is out of order due to long-term use, it is automatically re-guided, and operation at the reference position is always possible. Here, after passing through both guide taper surfaces, the engaging convex part comes into contact with the ascending / descending slope and lifts the moving member, but at this time the engaging convex part moves and malfunctions, It is necessary to set the frictional force so that it is much greater than the force required to lift the moving member.

次にプロペラ形状の係合体の、軸心を挟んだ係合凸部とは逆端部に一定長さの強制解除用突起を形成しておく。すると強制解除用突起は開閉移動体の最も前部に位置することになる。また地震の揺れが発生して閉止動作になった状態でも開閉移動体は前述のように係合凸部が係止突起に係合するまでの僅かな距離のみは移動させることが可能である。そこで、強い地震により家具等の収納装置自体が大きく傾いてしまい、転動体が解除位置に自然復帰せずに開閉移動体を開けることができなくなったような状況でも、僅かに開放した隙間から細いものを差し込んで強制解除用突起を上下方向に移動させると、逆側の係合凸部がシーソー動作により係止突起から外れる動作が得られ、強制解除が可能になる。   Next, a forcible release protrusion having a certain length is formed at the end of the propeller-shaped engagement body opposite to the engagement projection with the axis interposed therebetween. Then, the forcible release protrusion is positioned at the foremost part of the opening / closing moving body. Even in the state where the shaking of the earthquake occurs and the closing operation is performed, the opening / closing moving body can be moved only a small distance until the engaging convex portion engages with the locking projection as described above. Therefore, even in a situation where the storage device itself such as furniture is greatly inclined due to a strong earthquake, and the rolling element cannot be opened naturally without returning to the release position, it is thin from the slightly opened gap. When an object is inserted and the forcible release protrusion is moved in the vertical direction, an operation in which the opposite-side engaging projection is disengaged from the engaging protrusion by the seesaw operation is obtained, and forcible release is possible.

開閉移動体の最終閉鎖段階において、受け装置の係合凸部が本体装置の係止突起上部を通過した後で移動部材を持ち上げて転動体が転がる空間を形成し、その空間を転動体が転動している間は係止突起を有する移動部材が転動体の上に乗った状態になり下方に下がらないようにすることで、係合凸部を係止突起に係合させて移動体の開放を阻止する構成であるため、転動体が極僅かに解除位置から転がった段階で即座に開閉移動体の開放動作を阻止することができ、非常に感度のよい閉止動作が得られる。   In the final closing stage of the opening / closing moving body, after the engaging convex part of the receiving device passes the upper part of the locking projection of the main body device, the moving member is lifted to form a space where the rolling element rolls, and the rolling element rolls in that space. While moving, the moving member having the locking projection is in a state of riding on the rolling element and does not drop downward, so that the engaging projection is engaged with the locking projection to move the moving body. Since the opening is prevented, the opening / closing moving body can be immediately prevented from opening when the rolling element rolls slightly from the release position, and a highly sensitive closing operation can be obtained.

地震による揺れが収まると転動体は本体ケースの傾斜底面により解除位置に自然復帰し、そのままで数秒待つだけで移動体の開放動作が再度実施可能になる。また、移動体が僅かに開放した閉止状態で揺れが収束した場合は、転動体の頂点に移動部材が乗ったままの状態になる場合も想定されるが、この場合は一度開閉移動体を完全に閉鎖位置にまで閉じると転動体と移動部材の下部幅広面との接触が回避され、同様に数秒待機するだけで開放動作を再度実施可能にすることができる。   When the shaking due to the earthquake is settled, the rolling element spontaneously returns to the release position by the inclined bottom surface of the main body case, and the moving body can be opened again just by waiting for a few seconds. In addition, when the shaking converges in a closed state in which the moving body is slightly opened, it may be assumed that the moving member remains on the top of the rolling element. When closed to the closed position, contact between the rolling element and the lower wide surface of the moving member is avoided, and the opening operation can be performed again by simply waiting for a few seconds.

また開閉移動体の開放状態で地震が発生した場合でも、そのまま開閉移動体を閉鎖させることができ、そして一旦完全に閉鎖させると今度は引き続き揺れが発生している状態であれば同様にその後の開閉移動体の開放を阻止する閉止動作が得られる。   In addition, even if an earthquake occurs when the open / close moving body is open, the open / close moving body can be closed as it is, and once it is completely closed, if it continues to shake, A closing operation for preventing the opening / closing moving body from being opened is obtained.

受けケ−スに対して係合体が一定の摩擦力を有した状態で回転移動するように設定したため、移動体の最終閉鎖段階で本体ケースの案内用テーパー面と係止突起の案内用テーパー面に沿って受け装置の係合凸部が案内されて挿入し、自動的に本体装置に対する係合凸部の上下位置が基準位置に配置され、常に適正な移動部材の持ち上げ量を得ることができる。また、長期間の使用途中で万一双方の位置が狂った場合においても、その次の開閉動作で自動的に再度案内し直すことになり、常に基準位置での作動が可能になる。   Since the engaging body is set so as to rotate and move with a constant frictional force with respect to the receiving case, the guiding taper surface of the main body case and the guiding taper surface of the locking projection at the final closing stage of the moving body The engagement convex portion of the receiving device is guided and inserted along, and the vertical position of the engagement convex portion with respect to the main body device is automatically arranged at the reference position, and an appropriate lifting amount of the moving member can always be obtained. . In addition, even if both positions go wrong during a long-term use, the next opening / closing operation automatically re-guides them, so that the operation at the reference position is always possible.

また、予期せぬ事態により係合凸部が係止突起に係合したまま外れなくなり、開閉移動体を大きく開放でき無くなった非常時においても、僅かに開いた閉止状態での開閉移動体と設置枠体との隙間から細いものを差し込んで強制解除用突起を押す動作だけで係合凸部を係止突起から外すことができ、開閉移動体を簡単な操作で強制開放させることが可能である。   In addition, even in the event of an emergency in which the engaging projection does not come off while engaging with the locking projection due to an unexpected situation, and the opening / closing moving body cannot be opened largely, the opening / closing moving body in the slightly opened closed state is installed. The engaging protrusion can be removed from the locking protrusion by simply inserting a thin object from the gap with the frame and pushing the forcible release protrusion, and the open / close moving body can be forcibly released by a simple operation. .

本体ケースと転動体と移動部材とからなる本体装置と、受けケ−スと係合体とからなる受け装置のみで構成され、部品点数も少なく組み立ても簡単な単純であり、転動体以外は樹脂の成型品にて製作可能で安価に生産可能である。   Consists of a main unit consisting of a main body case, rolling elements and moving members, and a receiving apparatus consisting of a receiving case and an engaging body. The number of parts is simple and assembly is simple. It can be manufactured as a molded product and can be produced at low cost.

本体ケースを比較的薄い箱状にて形成し、その内部に転動体と移動部材を組み込み、薄い受けケ−スに同様の薄い板状の係合体を組付ける構成にすることにより、引き出しの設置枠体に相当する枠体内側面に掘り込んで本体装置を装着することができ、かつ枠体内側面と引き出し外側面間の細い隙間に受け装置を配置する構成が可能になり、閉止装置全体としても収納スペース内に取り付けることなく、さらには露出し無いデザイン性に優れた形態にすることができる。   The main body case is formed in a relatively thin box shape, a rolling element and a moving member are incorporated inside it, and a similar thin plate-like engagement body is assembled to a thin receiving case, thereby setting up the drawer. The main body device can be mounted by digging into the side of the frame body corresponding to the frame body, and the receiving device can be arranged in a narrow gap between the side surface of the frame body and the outer surface of the drawer. Without being installed in the storage space, it can be made a form excellent in design that is not exposed.

以下図面に基づいて本発明の耐震閉止装置の実施の形態を説明する。本発明の閉止装置は様々な収納部材の開閉移動体と設置枠体に振り分けて装着可能であるが、実施形態としては前後に押し引きして開閉する引き出しの、設置枠体に相当する枠体内側面26に本体装置aを掘り込んだ状態で装着し、開閉移動体に相当する引き出し本体30の外側面に受け装置bを装着した設定にて説明する。図1は本体装置aの斜視図であり、図2は設置枠体の枠体内側面26に本体装置aを装着した状態の納まり正面図である。   Embodiments of the seismic closing device of the present invention will be described below with reference to the drawings. The closing device of the present invention can be attached to the opening / closing moving body and the installation frame body of various storage members. However, in the embodiment, the drawer body that corresponds to the installation frame body of the drawer that opens and closes by pushing back and forth is used. The description will be made with the setting in which the main body device a is dug in the side surface 26 and the receiving device b is mounted on the outer surface of the drawer main body 30 corresponding to the opening / closing moving body. FIG. 1 is a perspective view of the main body device a, and FIG. 2 is a front view of the main body device a in a state where the main body device a is mounted on the side surface 26 of the installation frame.

図1および図2に示すように、本体装置aは本体ケース1と移動部材5と転動体18と本体フタ16とから構成される。図3は本体ケース1の正面図を、図4は図3のA−A‘断面図を示している。図3に示すように本体ケース1はつば部分2を有した箱形状であり、正面中央位置に2ヵ所の異型開口窓3を設けておく。そして本体ケース1の内部下面を一定の傾斜角度を有した傾斜底面4にて形成する。このとき傾斜の向きは図2に示すように引き出しの前面側が高く奥に向かって低くなるように設定しておく。また図4に示すように本体ケース1の開口窓3付近である中央部分の厚みを、つば部分2の厚みよりも薄く設定しておく。   As shown in FIGS. 1 and 2, the main body device a includes a main body case 1, a moving member 5, a rolling element 18, and a main body lid 16. 3 is a front view of the main body case 1, and FIG. 4 is a cross-sectional view taken along line A-A 'of FIG. As shown in FIG. 3, the main body case 1 has a box shape having a collar portion 2, and two odd-shaped opening windows 3 are provided at the front center position. The inner lower surface of the main body case 1 is formed by an inclined bottom surface 4 having a certain inclination angle. At this time, the direction of the inclination is set so that the front side of the drawer is high and low as shown in FIG. Further, as shown in FIG. 4, the thickness of the central portion in the vicinity of the opening window 3 of the main body case 1 is set to be thinner than the thickness of the collar portion 2.

図5は移動部材5の正面図であり、図6は側面図である。図5に示すように移動部材5は略矩形形状で正面側の縦面に係止突起6と昇降斜面7を、裏面側の縦面に案内溝11を有し、図6に示すように下部は下部幅広面10にて形成する。そして図5に示すように昇降斜面7は傾斜面8とそれに連続する平坦面9とから形成し、係止突起6は円弧状部分12を有しており、円弧状部分12にさらに一段没している引っ掛かり部分13を設けておく。このとき移動部材5の前側に係止突起6が配置され、少し間隔を置いた位置から傾斜面8に続いて平坦面9となるように昇降斜面7を配置しておく。そして係止突起6の円弧状部分12の上部位置が昇降斜面7の平坦面9とほぼ水平になるように両者の上下位置を設定しておく。また移動部材5の下側の下部幅広面10にも前述の本体ケース1の傾斜底面4と同じ角度の傾斜を設けておく。さらに移動部材5の昇降斜面7を設けたのと逆の裏面に斜めの案内溝11を設けておく。図7は本体フタ16の正面図であり、本体ケース1の裏側に嵌るような形状で、本体ケース1の内側に突出する配置で斜めの案内凸部17を設けておく。   FIG. 5 is a front view of the moving member 5, and FIG. 6 is a side view. As shown in FIG. 5, the moving member 5 has a substantially rectangular shape, and has a locking projection 6 and an elevating slope 7 on the vertical surface on the front side, a guide groove 11 on the vertical surface on the back side, and a lower portion as shown in FIG. Is formed by the lower wide surface 10. As shown in FIG. 5, the ascending / descending slope 7 is formed of an inclined surface 8 and a flat surface 9 continuous therewith, and the locking projection 6 has an arcuate portion 12, and is further submerged in the arcuate portion 12. A hooking portion 13 is provided. At this time, the locking projection 6 is arranged on the front side of the moving member 5, and the elevating slope 7 is arranged so as to become the flat surface 9 following the inclined surface 8 from a position at a slight interval. Then, the upper and lower positions of the arcuate portion 12 of the locking projection 6 are set so that the upper position of the arcuate portion 12 is substantially horizontal with the flat surface 9 of the elevating slope 7. In addition, the lower wide surface 10 on the lower side of the moving member 5 is also provided with an inclination of the same angle as the inclined bottom surface 4 of the main body case 1 described above. Furthermore, an inclined guide groove 11 is provided on the reverse side of the moving member 5 which is provided with the up-and-down slope 7. FIG. 7 is a front view of the main body lid 16, and an oblique guide convex portion 17 is provided in a shape that fits on the back side of the main body case 1 and is arranged so as to protrude inside the main body case 1.

次に本体ケース1の裏側から移動部材5を挿入し、昇降斜面7と係止突起6が2ヵ所の開口窓3から突出する向きで配置し、金属製の球体である転動体18を同時に挿入する。すると転動体18は傾斜底面4の最も低い奥位置に自然に配置されて停止し、この転動体18の位置を解除位置とする。そして本体フタ16の案内凸部17が移動部材5の案内溝11に嵌った状態で、本体フタ16を本体ケース1に被せて本体装置aを構成する。ここで移動部材5は本体ケース1内で案内溝11と案内凸部17により斜め上方にスライド移動可能に設定し、従って両開口窓3は係止突起6と昇降斜面7が突出した状態で斜め上方にスライド移動できるように形成しておく。   Next, the moving member 5 is inserted from the back side of the main body case 1, the elevating slope 7 and the locking projection 6 are arranged so as to protrude from the two opening windows 3, and the rolling element 18 which is a metal sphere is inserted at the same time. To do. Then, the rolling element 18 is naturally disposed at the lowest back position of the inclined bottom surface 4 and stops, and the position of the rolling element 18 is set as a release position. And the main body cover 16 is covered with the main body case 1 in the state which the guide convex part 17 of the main body cover 16 fitted in the guide groove 11 of the moving member 5, and the main body apparatus a is comprised. Here, the moving member 5 is set so as to be slidable obliquely upward in the main body case 1 by the guide groove 11 and the guide convex portion 17, so that both the opening windows 3 are inclined with the locking projection 6 and the elevating slope 7 projecting. It is formed so that it can be slid upward.

図8は受け装置bの斜視図であり、図9は受け装置bを引き出し外側面28の最前部に取り付けた状態の正面図である。図8に示すように受け装置bは薄い板状の受けケース19と同様に薄いプロペラ状の係合体20を重ね合わせた構成である。図10は受けケース19の正面図であり、図11は係合体20の正面図である。図8及び図10に示すように受けケース19は略長方形で、長手方向の上下端に振れ止め用凸部21を設け、中央部分に軸心挿入孔22を形成しておく。また図8及び図11に示すように係合体20は中央部分に軸心23を有し、両端に向かって先細り形状で、片端部に円柱形状で先端に引っ掛かり部分13を有した係合凸部24を設け、他端部に一定の幅を有した強制解除用突起25を設けておく。   FIG. 8 is a perspective view of the receiving device b, and FIG. 9 is a front view of a state in which the receiving device b is pulled out and attached to the forefront portion of the outer side surface 28. As shown in FIG. 8, the receiving device “b” has a configuration in which thin propeller-like engaging bodies 20 are overlapped similarly to the thin plate-like receiving case 19. FIG. 10 is a front view of the receiving case 19, and FIG. 11 is a front view of the engaging body 20. As shown in FIGS. 8 and 10, the receiving case 19 has a substantially rectangular shape, and is provided with a steady-state convex portion 21 at the upper and lower ends in the longitudinal direction, and an axial insertion hole 22 is formed at the center portion. Further, as shown in FIGS. 8 and 11, the engaging body 20 has an axial center 23 at the center portion, is tapered toward both ends, is a cylindrical shape at one end portion, and is an engaging convex portion having a hooked portion 13 at the tip end. 24, and a forcible release protrusion 25 having a certain width is provided at the other end.

そして受けケース19に軸心23を中心に一定角度範囲のみ回転可能な状態で係合体20を組付け、Eリング等で抜け止めを施して受け装置bを構成する。図9は受けケース19に対して係合体20が基準位置に配置された状態を示しており、この基準状態では係合凸部24と軸心23と強制解除用突起25が水平方向に一直線に並んだ位置になっている。そして図9に示すように強制解除用突起25が引き出し外側面28の前側に配置された状態で受け装置bを装着する。図12は基準位置から係合体20を回転させた状態を示しており、係合体20は基準位置から両方向に一定角度ずつ回転によるシーソー動作が可能なように構成しておく。またここで重要な点としては、係合体20は回転動作の際に一定の摩擦力がかかった状態でシーソー動作するように設定しておき、移動後に任意の位置で停止させた段階では、所定以上の力を加えない限り係合体20はそのままの位置で保持されるようにしておく。この摩擦力を与える手段は特に限定されないが、抜け止めを施す際に皿ばねのような弾性を有する部材を挟み込む方法や、係合体20に弾性突起を設け、受けケース19に係合体20の弾性突起を挟み込むようにする方法等が簡単である。また摩擦力ではなく、両者に細かいローレットのような凹凸を設けておき、カチカチと移動して任意の位置で保持させる構成であっても良い。   Then, the engaging body 20 is assembled to the receiving case 19 so as to be able to rotate only within a certain angular range around the shaft center 23, and the receiving device b is configured by preventing it from coming off with an E ring or the like. FIG. 9 shows a state in which the engagement body 20 is disposed at the reference position with respect to the receiving case 19. In this reference state, the engagement convex portion 24, the shaft center 23, and the forcible release projection 25 are aligned in the horizontal direction. They are lined up. Then, as shown in FIG. 9, the receiving device b is mounted in a state in which the forcible release protrusion 25 is disposed on the front side of the drawer outer surface 28. FIG. 12 shows a state in which the engagement body 20 is rotated from the reference position, and the engagement body 20 is configured so as to be able to perform a seesaw operation by rotation by a certain angle in both directions from the reference position. Further, as an important point here, the engagement body 20 is set so as to perform a seesaw operation in a state where a constant frictional force is applied during the rotation operation, and at a stage where the engagement body 20 is stopped at an arbitrary position after the movement, As long as the above force is not applied, the engagement body 20 is held in the same position. The means for applying the frictional force is not particularly limited, but a method of sandwiching a member having elasticity such as a disc spring when retaining is used, or an elastic protrusion is provided on the engagement body 20, and the elasticity of the engagement body 20 is provided on the receiving case 19. A method of sandwiching the protrusion is simple. Further, instead of the frictional force, there may be a configuration in which irregularities such as fine knurls are provided on both sides, and they are moved and held at arbitrary positions.

次に本体装置aと受け装置bを設置枠体である枠体内側面26と開閉移動体である引き出し外側面28に振り分けて装着する。図13は受け装置bを引き出し外側面28に装着した断面図であり、図14は本体装置aを枠体内側面26に掘り込んだ状態で装着した断面図であり、図15は本体装置aと受け装置b両方を枠体内側面26と引き出し外側面28に装着し、両者が面対している状態を示した断面図である。ここで受け装置bは図15に示すように本体装置aの中央部分の枠体内側面26からほとんど出っ張っていない範囲内で面対し、共に突出している係合体20の係合凸部24と移動部材5の係止突起6と昇降斜面7のみが当接するように構成する。つまり枠体内側面26と引き出し外側面28の隙間寸法に応じて本体装置aと受け装置bの左右方向の配置を適宜納まりに合わせて設定しておく。このとき設置枠体に対する引き出し本体30の横方向に振れを受けケースの振れ止め用凸部21の高さを適宜設定して規制しておくと良い。   Next, the main body device a and the receiving device b are distributed and attached to the side surface 26 in the frame that is the installation frame and the outer side surface 28 of the drawer that is the open / close moving body. 13 is a cross-sectional view in which the receiving device b is mounted on the outer side surface 28 of the drawer, FIG. 14 is a cross-sectional view in which the main body device a is mounted in a state of digging into the side surface 26 in the frame, and FIG. It is sectional drawing which showed the state which mounted | worn both receiving device b to the frame inner side surface 26 and the drawer outer side surface 28, and both faced each other. Here, as shown in FIG. 15, the receiving device b faces the surface of the central portion of the main body device a within a range that hardly protrudes from the frame body 26, and the engaging projection 24 and the moving member of the engaging body 20 projecting together. 5 is configured such that only the locking protrusion 6 and the elevating slope 7 are in contact with each other. That is, the arrangement of the main body device a and the receiving device b in the left-right direction is appropriately set according to the fit according to the gap size between the frame inner side surface 26 and the drawer outer side surface 28. At this time, it is preferable that the height of the steady-state convex portion 21 of the case that receives the vibration in the lateral direction of the drawer body 30 with respect to the installation frame is appropriately set and regulated.

そして本体装置aと受け装置bの上下方向の位置関係においては、引き出し本体30が完全に閉じる直前に受け装置bの係合凸部24が、本体装置aの係止突起6の上端の案内用テーパー面15と本体ケース1の案内用テーパー面15との中間位置を通過するように設定し、本体装置aと受け装置bの前後方向の配置においては、完全に引き出し本体30が閉鎖した状態で昇降斜面7の平坦面9の中央位置に係合体20の係合凸部24が位置するように設定しておく。   In the vertical positional relationship between the main body device a and the receiving device b, the engaging convex portion 24 of the receiving device b is used for guiding the upper end of the locking projection 6 of the main body device a immediately before the drawer main body 30 is completely closed. It is set so as to pass through an intermediate position between the taper surface 15 and the guide taper surface 15 of the main body case 1, and the main body device a and the receiving device b are arranged in the front-rear direction with the drawer body 30 completely closed. It is set so that the engaging convex portion 24 of the engaging body 20 is positioned at the center position of the flat surface 9 of the ascending / descending slope 7.

上記のように構成した状態からの、引き出し本体30の開閉動作と地震発生時の揺れによる閉止動作を図16に基づいて以下に説明する。ここで実際には、本体装置aと受け装置bは閉鎖最終段階で全体が面対するのであるが、わかりやすく表記するために図16では受け装置bは係合凸部24のみを表記する。つまり重要なのは本体装置aと受け装置bの係合凸部24の関係であるため、本体装置aに対する係合凸部24の動作として述べても差し支えは無い。図16(a)に示す最も本体装置aから離れて表記されている係合凸部24は引き出し本体30が大きく開放されている状態での位置を示しており、このとき転動体18は傾斜底面4の最も低い奥の位置に停止しており、移動部材5は本体ケース1内で最も下がった状態になっている。   The opening / closing operation of the drawer main body 30 and the closing operation due to the shaking at the time of earthquake will be described below with reference to FIG. Here, in practice, the main body device a and the receiving device b face each other at the final stage of closing, but for the sake of easy understanding, the receiving device b shows only the engaging projection 24 in FIG. In other words, what is important is the relationship between the engagement convex portion 24 of the main body device a and the receiving device b, and therefore there is no problem even if it is described as the operation of the engagement convex portion 24 with respect to the main body device a. In FIG. 16 (a), the engagement convex portion 24 shown most distant from the main body device a indicates the position in the state in which the drawer main body 30 is largely opened. At this time, the rolling elements 18 are inclined bottom surfaces. 4 is stopped at the lowest back position, and the moving member 5 is in the lowest position in the main body case 1.

この大きく開放した状態から引き出し本体30を閉じると、図16(a)の矢印の順に示すように係合凸部24は移動部材5の係止突起6の上端を通過する。そして微小距離さらに閉鎖された段階で係合凸部24が移動部材5の昇降斜面7の傾斜面8に当接する。すると移動部材5を持ち上げる動作になり、図16(b)に示すように移動部材5の案内溝11と本体フタ16の案内凸部17により斜め上方にスライド移動する。そしてさらに微小距離閉鎖すると図16(c)に示すように係合凸部24は昇降斜面7の平坦面9に乗った状態になる。この平坦面9が係合凸部24に乗った位置がもっとも移動部材5が持ち上がった状態であり、完全に引き出し本体30が閉鎖したときにこの状態になるように設定しておく。ここで平坦面9を奥行き方向に一定の長さを有しているように形成しておく。すると完全に引き出し本体30が閉じたときの奥行き方向の位置がばらついたりした場合においても、確実に所定の高さまで移動部材5を持ち上げることができる。そして図16(c)の状態で、持ち上がっている移動部材5の下部幅広面10と傾斜底面4との空間が常に平行でかつ転動体18の直径よりも僅かに広くなるように設定しておく。   When the drawer main body 30 is closed from this largely open state, the engaging protrusion 24 passes through the upper end of the locking protrusion 6 of the moving member 5 as shown in the order of the arrows in FIG. Then, when the minute distance is further closed, the engaging convex portion 24 comes into contact with the inclined surface 8 of the elevating slope 7 of the moving member 5. Then, the moving member 5 is lifted, and is slid obliquely upward by the guide groove 11 of the moving member 5 and the guide convex portion 17 of the main body lid 16 as shown in FIG. When the distance is further closed, the engaging convex portion 24 is on the flat surface 9 of the ascending / descending slope 7 as shown in FIG. The position where the flat surface 9 rides on the engaging convex portion 24 is the state where the moving member 5 is lifted most, and is set so that this state is obtained when the drawer body 30 is completely closed. Here, the flat surface 9 is formed so as to have a certain length in the depth direction. Then, even when the position in the depth direction when the drawer body 30 is completely closed varies, the moving member 5 can be reliably lifted to a predetermined height. In the state shown in FIG. 16C, the space between the lower wide surface 10 and the inclined bottom surface 4 of the moving member 5 that is lifted is set to be always parallel and slightly wider than the diameter of the rolling element 18. .

次に図16(c)の閉鎖状態から引き出し本体30を開放させると、昇降斜面7の平坦面9から係合凸部24が外れ移動部材5は自重により斜め下方に落下し始め、図16(b)の状態を経て図16(a)の位置に復帰することになる。つまり上記のような通常での開閉動作においては、引き出し本体30の閉鎖最終段階と開放初期段階で受け装置bの係合凸部24により本体装置aの移動部材5が所定の寸法のみ上下方向に移動するだけの動作を繰り返すことになる。ここで開閉動作中に受け装置bと本体装置aとが接触するのは、係合凸部24が昇降斜面7の傾斜面8に当接するときだけであり、比較的なだらかな傾斜面8に当接する動作であるため衝突音や衝撃は比較的少ないと想定される。しかし小さい音なりが発生することは考えられ、この音をもさらに極力無くする必要がある。そこで傾斜面8の角度をよりなだらかにして当接時の衝撃を小さくするか、若しくは傾斜面8の当接ヵ所に軟質の衝撃吸収材等を取り付けると発生する音を減少させることができる。   Next, when the drawer body 30 is opened from the closed state shown in FIG. 16C, the engaging convex portion 24 comes off from the flat surface 9 of the ascending / descending slope 7, and the moving member 5 starts to fall obliquely downward due to its own weight. It will return to the position of Fig.16 (a) through the state of b). That is, in the normal opening / closing operation as described above, the movable member 5 of the main body device a is moved up and down by a predetermined dimension by the engaging convex portion 24 of the receiving device b at the final closing stage and the initial opening stage of the drawer main body 30. The movement is simply repeated. Here, the receiving device b and the main body device a are in contact with each other during the opening / closing operation only when the engaging convex portion 24 comes into contact with the inclined surface 8 of the elevating slope 7 and hits the relatively gentle inclined surface 8. It is assumed that there are relatively few impact sounds and impacts because of the contact operation. However, it is conceivable that a small sound is generated, and it is necessary to eliminate this sound as much as possible. Therefore, if the angle of the inclined surface 8 is made gentler to reduce the impact at the time of contact, or if a soft impact absorbing material or the like is attached to the contact portion of the inclined surface 8, the generated sound can be reduced.

そして閉鎖状態で地震が発生すると、弱い揺れであってもまず最初に図17(a)に示すように転動体18が本体ケース1内で転動する。そこで図17では転動体18が本体ケース1内で転動している状態として、転動体18を複数個表示している。そしてそのまま揺れが収束すると転動体18は傾斜底面4により解除位置に自然復帰するため、そのまま引き出しを開放することができる。しかしさらに大きな揺れが発生すると引き出し本体30が開放しはじめ、引き出し本体30に装着された係合凸部24を有する受け装置bもいっしょに開放移動することになる。ところが地震による揺れは続いているため転動体18は本体ケース1内で転動しており、したがって係合凸部24が平坦面9から外れても図17(b)に示すように移動部材5の下部幅広面10が転動体18の頂点に乗った状態になり落下する動作にはならない。すると当然移動部材5の係止突起6も持ち上がったままであるため、さらに引き出し本体30が開放すると図17(c)のように係合凸部24が係止突起6に係合してこの位置で係止され、その結果引き出し本体30の開放を阻止することが可能になる。   When an earthquake occurs in the closed state, the rolling element 18 first rolls in the main body case 1 as shown in FIG. Accordingly, in FIG. 17, a plurality of rolling elements 18 are displayed as the rolling elements 18 are rolling in the main body case 1. When the shaking converges as it is, the rolling element 18 naturally returns to the release position by the inclined bottom surface 4, so that the drawer can be opened as it is. However, when a greater shaking occurs, the drawer body 30 begins to open, and the receiving device b having the engaging projections 24 attached to the drawer body 30 also moves together. However, since the shaking due to the earthquake continues, the rolling element 18 rolls in the main body case 1, and therefore, even if the engaging convex portion 24 is detached from the flat surface 9, as shown in FIG. The lower wide surface 10 is on the top of the rolling element 18 and does not fall. Then, of course, the locking projection 6 of the moving member 5 also remains lifted. Therefore, when the drawer body 30 is further opened, the engaging projection 24 engages with the locking projection 6 as shown in FIG. As a result, it becomes possible to prevent the drawer body 30 from being opened.

また図16に示す通常の開閉操作で転動体18が解除位置に停止している状態では、移動部材5は斜め上下スライド動作において転動体18と干渉してはいけない。ところが揺れにより少しでも転動体18が解除位置から外れると今度は即座に下部幅広面10が転動体18の頂点に乗って移動部材5の落下を制限する必要がある。そこでこの二つの必要条件を満たす手段としては、通常の開閉動作による移動部材5の上下動作で両者がぎりぎり接触しない設定で移動部材5の奥側下部コーナー14を案内溝11と平行にカットしておくと良い。すると図16(c)の閉鎖状態において、移動部材5のカットされた奥側下部コーナー14と下部幅広面10との交点を解除位置での転動体18の頂点に非常に接近させることができる。その結果図17(b)に示すように転動体18が解除位置から極僅かだけ転動した位置でも即座に移動部材5の斜め落下動作を規制できることになり、非常に感度の良い閉止動作が得られることになる。   Further, in a state where the rolling element 18 is stopped at the release position by the normal opening / closing operation shown in FIG. 16, the moving member 5 should not interfere with the rolling element 18 in the oblique vertical slide operation. However, if the rolling element 18 moves out of the release position even by a small amount, it is necessary to immediately limit the lower wide surface 10 on the top of the rolling element 18 to limit the falling of the moving member 5. Therefore, as means for satisfying these two requirements, the lower lower corner 14 of the moving member 5 is cut in parallel with the guide groove 11 so that the moving member 5 is not in contact with the vertical movement of the moving member 5 by the normal opening / closing operation. It is good to leave. Then, in the closed state of FIG. 16 (c), the intersection of the cut back lower corner 14 and the lower wide surface 10 of the moving member 5 can be made very close to the apex of the rolling element 18 at the release position. As a result, as shown in FIG. 17 (b), even when the rolling element 18 rolls very slightly from the release position, the oblique dropping operation of the moving member 5 can be immediately controlled, and a highly sensitive closing operation is obtained. Will be.

ここで、閉鎖状態である図17(a)から開放を阻止する図17(c)までの移動距離を閉止移動距離とすると、この距離は引き出し本体30を完全に開け放ったときの全体の開放距離に対しては非常に小さく、収納物が飛び出したりはしないため特に問題にはならない。また強い揺れにより引き出し本体30が瞬時に勢いよく開放しようとした時には、係止突起6と係合凸部24に非常に大きな力がかかるため、係合凸部24と係止突起6は強度を有するように設定しておき、さらに閉止状態で互いが滑らないように両者の先端に嵌り合うような引っ掛かり部分13を設けておくとよい。また地震による揺れが収束した段階では移動部材5が転動体18に乗ったままになってしまうこともあり、その場合は一旦引き出し本体30を完全に閉鎖させるとよい。すると係合凸部24が平坦面9をごく僅かに持ち上げて転動体18と移動部材5の下部幅広面10との接触を排除できることになり、転動体18は自然に解除位置に復帰する。したがってその後は再度通常どおりの開閉操作が可能である。   Here, when the movement distance from FIG. 17 (a) in the closed state to FIG. 17 (c) that prevents the opening is the closing movement distance, this distance is the total opening distance when the drawer body 30 is fully opened. Is very small and the stored items do not pop out, so this is not a problem. In addition, when the drawer body 30 tries to open momentarily and vigorously due to strong shaking, a very large force is applied to the locking projection 6 and the engaging projection 24, so that the engaging projection 24 and the locking projection 6 have strength. It is preferable to provide a catching portion 13 that fits at both ends so that they do not slip in the closed state. In addition, the moving member 5 may remain on the rolling element 18 at the stage when the shaking due to the earthquake has converged. In this case, the drawer body 30 may be once completely closed. Then, the engagement convex part 24 lifts the flat surface 9 very slightly, and the contact between the rolling element 18 and the lower wide surface 10 of the moving member 5 can be eliminated, and the rolling element 18 naturally returns to the release position. Therefore, the normal opening / closing operation can be performed again thereafter.

つまり上記の構成では、受け装置bの係合凸部24が本体装置aの昇降斜面7の傾斜面8に当接してから平坦面9にまで移動する動作での、移動部材5を持ち上げる上下方向の距離が非常に重要になる。例えば引き出し本体30が設置枠体に対して所定の位置より低く取り付けられてしまった場合などでは、この持ち上げ距離が不足することになり、閉鎖状態で地震による揺れが発生しても移動部材5の下部幅広面10に転動体18の頂点が当たってしまい、本体ケース1内で転動体18が自由に転動せず、誤作動を引き起こすことが想定される。   That is, in the above configuration, the up-and-down direction for lifting the moving member 5 in the operation in which the engagement convex portion 24 of the receiving device b moves to the flat surface 9 after contacting the inclined surface 8 of the elevating slope 7 of the main body device a. The distance of becomes very important. For example, when the drawer body 30 is attached to the installation frame lower than a predetermined position, the lifting distance is insufficient, and even if the shaking due to the earthquake occurs in the closed state, the moving member 5 It is assumed that the apex of the rolling element 18 hits the lower wide surface 10, and the rolling element 18 does not roll freely in the main body case 1, thereby causing a malfunction.

そこで設置枠体と開閉移動体に本体装置aと受け装置bを装着する際の取り付け誤差や長期間使用による垂れ下がり等にも対処できる方法が必要である。その方法は多種考えられるが、もっとも有効な手段は、本体装置aに対して必ず同じ位置に受け装置bの係合凸部24が配置されるように、受けケース19内で係合体20の係合凸部24位置が自動案内されればよいと考えられる。そこで前述の受けケース19に対して係合体20が摩擦力を受けながら一定角度範囲内で回転動作する構成や、両者に細かいローレットのような凹凸を設けておき、カチカチと移動して任意の位置で保持させる構成が有効である。   Therefore, there is a need for a method that can cope with mounting errors when mounting the main body device a and the receiving device b on the installation frame body and the opening / closing moving body, and drooping due to long-term use. Although various methods are conceivable, the most effective means is the engagement of the engaging body 20 in the receiving case 19 so that the engaging convex part 24 of the receiving device b is always arranged at the same position with respect to the main body device a. It is considered that the position of the joint convex portion 24 may be automatically guided. Therefore, a configuration in which the engaging body 20 rotates within a certain angle range while receiving frictional force with respect to the receiving case 19 described above, or fine irregularities such as knurls are provided on both, and the cradle moves to an arbitrary position. It is effective to hold the

例えば摩擦力を用いた方法では、図8に示す状態で受けケース19に対して係合体20はある程度の摩擦力がかかった状態でその位置にて保持されており、所定以上の力がかかると軸心23を中心に回転してシーソー動作することになる。従って本体ケース1の案内用テーパー面15と係止突起6上部の案内用テーパー面15間の隙間寸法をかろうじて係合凸部24が通過できる程度に設定しておくと良い。そして係合凸部24は円柱状にて形成し、両案内用テーパー面15を前部が広く奥部が狭くなるように向かい合わせて配置しておく。すると係合凸部24を有する受け装置bが基準位置から上下方向にずれた状態で装着されたまま引き出し本体30が閉鎖されたとしても、どちらかの案内用テーパー面15に係合凸部24が当接し、同時に摩擦力に打ち勝って両案内用テーパー面15に案内されて係合体20が少しだけ回転して係合凸部24が略上下方向にシーソー移動する動作になる。そして両案内用テーパー面15間を通過した段階で係合凸部24はそのまま保持されることになり、常に基準位置にて係合凸部24は昇降斜面7の傾斜面8に当接することになる。その結果常に最適な位置まで移動部材5を持ち上げることが可能になる。   For example, in the method using the frictional force, the engagement body 20 is held at the position with a certain amount of frictional force applied to the receiving case 19 in the state shown in FIG. The seesaw operation is performed by rotating around the axis 23. Therefore, it is preferable to set the gap dimension between the guiding taper surface 15 of the main body case 1 and the guiding taper surface 15 on the upper portion of the locking projection 6 so that the engaging convex portion 24 can pass through. The engaging convex part 24 is formed in a columnar shape, and both guide taper surfaces 15 are arranged facing each other so that the front part is wide and the back part is narrow. Then, even if the drawer main body 30 is closed while the receiving device b having the engaging convex portion 24 is mounted in a state of being deviated in the vertical direction from the reference position, the engaging convex portion 24 is formed on one of the guiding tapered surfaces 15. At the same time, overcoming the frictional force and being guided by both guide taper surfaces 15, the engagement body 20 rotates a little, and the engagement convex portion 24 moves in a seesaw direction in a substantially vertical direction. Then, the engagement convex portion 24 is held as it is when it passes between both guide taper surfaces 15, and the engagement convex portion 24 always comes into contact with the inclined surface 8 of the ascending / descending slope 7 at the reference position. Become. As a result, it is possible to always lift the moving member 5 to the optimum position.

この自動案内機構においては受けケース19と係合体20との摩擦力の強さの設定が重要であり、摩擦力が極端に小さいと両案内用テーパー面15を通過後昇降斜面7に当たった衝撃で係合凸部24が下方に動いてしまうことも考えられる。ここで引き出し本体30の閉鎖時に、係止突起6と案内用テーパー面15との当接により発生する力は非常に大きく、従って摩擦力をかなり強くしておいても自動案内動作には問題なく、つまり軽量な移動部材5自体を持ち上げるための比較的小さな衝突では絶対動かないように設定しておくことが必要である。また両案内用テーパー面15にて自動案内される動作は引き出し本体30を設置枠体に始めて組付けたときの最初の閉鎖動作時のみであり、その後の開閉動作においては、係合凸部24は案内された位置に保持されたまま開閉することになり、その後の開閉操作では自動案内のための当接音は発生しない。そして長期間使用中にこの上下方向の位置関係が狂った場合においても、その次の閉鎖動作にて再度自動案内し直すことになり、この機構は非常に有効と考えられる。   In this automatic guide mechanism, it is important to set the strength of the frictional force between the receiving case 19 and the engagement body 20, and if the frictional force is extremely small, the impact that hits the ascending / descending slope 7 after passing through both guide tapered surfaces 15 will be described. It is also conceivable that the engaging convex portion 24 moves downward. Here, when the drawer body 30 is closed, the force generated by the contact between the locking projection 6 and the guide taper surface 15 is very large. Therefore, even if the frictional force is considerably increased, there is no problem in the automatic guide operation. That is, it is necessary to set it so as not to move absolutely in a relatively small collision for lifting the lightweight moving member 5 itself. Further, the operation of being automatically guided by the both guide tapered surfaces 15 is only at the time of the first closing operation when the drawer body 30 is first assembled to the installation frame body, and in the subsequent opening / closing operation, the engagement convex portion 24 is operated. Is opened and closed while being held at the guided position, and a contact sound for automatic guidance is not generated in the subsequent opening and closing operation. Even when the positional relationship in the vertical direction is out of order during long-term use, automatic guidance is again performed in the next closing operation, and this mechanism is considered to be very effective.

また何らかの突発的な原因(1.地震の大きな揺れで収納部材全体が傾いてしまう、2.粘着物が付着してしまい転動体18が転動しなくなる、3.取付けねじが緩み本体ケース1が傾いて転動体18が解除位置に戻らなくなる、4.本体ケース1内で移動部材5や係止突起6等が大きく破損して噛み込んでしまう、等)により、係止突起6と係合凸部24との係合が外れなくなってしまい、引き出し本体30の開放ができ無くなる場合も考えられる。そこで、そのような場合においても収納部材自体を破損させること無く、引き出し本体30を強制開放できることが最近では要求されており、次にこの強制解除を可能とする構成を説明する。   In addition, some unexpected cause (1. The whole storage member is tilted by a large earthquake shake, 2. The sticking material adheres and the rolling element 18 does not roll. 3. The mounting screw is loosened and the body case 1 is 4. The rolling element 18 cannot be returned to the release position by tilting. 4. The movable member 5 or the locking projection 6 is damaged in the main body case 1 and is caught in the engagement projection 6. It is also conceivable that the engagement with the portion 24 is not released and the drawer body 30 cannot be opened. Therefore, in such a case, it has recently been required that the drawer body 30 can be forcibly opened without damaging the storage member itself. Next, a configuration that enables this forcible release will be described.

図18は例えば地震後に収納部材全体が前方向に傾いて係合凸部24と係止突起6が係合したままになり、引き出し本体30を開放できなくなった場合での閉止状態を示している。ここで図18に示す下段の引き出し本体30は図17(c)と同じ状態であり、完全に引き出し本体30が閉鎖している位置から閉止されるまでの閉止移動距離分のみ引き出し本体30は開放されている。従ってこの閉止移動距離を引き出し本体30の前板29の厚みよりもある程度大きく設定し、上段の引き出し本体30を閉鎖状態にしておくと、図18のように上方向から細いものであれば十分差し込むことが可能である。   FIG. 18 shows a closed state when, for example, the entire storage member is tilted forward after an earthquake and the engaging protrusion 24 and the locking projection 6 remain engaged and the drawer body 30 cannot be opened. . Here, the lower drawer body 30 shown in FIG. 18 is in the same state as FIG. 17C, and the drawer body 30 is opened only for the closing movement distance until the drawer body 30 is completely closed from the closed position. Has been. Accordingly, if this closing movement distance is set to be somewhat larger than the thickness of the front plate 29 of the drawer body 30, and the upper drawer body 30 is in a closed state, if it is thin from above as shown in FIG. It is possible.

また前述のように係合体20の軸心23を挟んだ係合凸部24の逆側には強制解除用突起25が設けられており、この強制解除用突起25を引き出し本体30の前板29位置に極力近づけて配置しておく。そして図18の状態において引き出し本体30の前板29と設置枠体の隙間の上方向から箸等の細いものを差し込んで強制解除用突起25を押すと、受けケース19と係合体20との摩擦に打ち勝って図12に示すように受けケース19内で係合体20を回転動作させることができる。すると強制解除用突起25が下方に下がり、係合凸部24がシーソー動作にて持ち上がり、その結果係止突起6と係合凸部24との係止を解除し、引き出し本体30を大きく開放させることが可能になる。   Further, as described above, the forcible release projection 25 is provided on the opposite side of the engagement convex portion 24 across the axis 23 of the engagement body 20, and the forcible release projection 25 is provided on the front plate 29 of the drawer body 30. Place it as close to the position as possible. In the state of FIG. 18, when a forcible release protrusion 25 is pushed by inserting a thin object such as chopsticks from above the gap between the front plate 29 of the drawer body 30 and the installation frame body, the friction between the receiving case 19 and the engagement body 20 Thus, the engagement body 20 can be rotated in the receiving case 19 as shown in FIG. Then, the forcible release projection 25 is lowered downward, and the engagement convex portion 24 is lifted by the seesaw operation. As a result, the engagement between the engagement projection 6 and the engagement convex portion 24 is released, and the drawer body 30 is largely opened. It becomes possible.

ところがシステムキッチン等の引き出しの場合では、図19に示すように設置枠体の一番上側の天板27が大きく前面に出っ張っている場合が多い。ここで上記のように、二段目から下の引き出し本体30の強制解除は、閉止移動距離を引き出し前板29の厚みに細いものを差し込める程度の隙間分を足した寸法に設定することで可能になる。しかし強制解除の操作方向を上からのみに限定すると一番上の引き出しにおいては天板27が飛び出している分さらに閉止移動距離を大きくしなければならず、閉止移動距離の違う本体装置aを複数個用意しておいて使い分けるか、どのような天板27にも対応できるような非常に閉止移動距離の長い本体装置aを全ての箇所に用いるかの処置が必要になる。   However, in the case of a drawer such as a system kitchen, the top plate 27 on the uppermost side of the installation frame body often protrudes to the front as shown in FIG. Here, as described above, the forcible release of the drawer body 30 below the second stage is performed by setting the closing movement distance to a dimension that adds a gap to the extent that a thin object can be inserted into the thickness of the drawer front plate 29. It becomes possible. However, if the operation direction of forced release is limited to only from above, the closing movement distance must be further increased by the amount of protrusion of the top plate 27 in the top drawer, and a plurality of main body devices a having different closing movement distances must be provided. It is necessary to prepare whether the main body device a having a very long closing movement distance that can be used for any top plate 27 is used in all places.

しかし天板27の前方向への出っ張りの寸法は様々であり、本体装置aの種類を増やすのは合理的では無い。また非常に長い閉鎖移動距離を有する本体装置aは当然長手方向に非常に大きなものになり、コスト面等においても非常に不適切である。さらには閉止移動距離が必要以上に長くなると、地震時の開放動作で閉止位置までに加速度や慣性力が付いてしまい、強度面においても問題が生じる恐れがある。ところが本発明の強制解除機構は基準位置からの上下両方向へのシーソー動作が可能であることが重要な特徴であり、したがって強制解除用突起25を下側から上に押しても解除することができる。つまり図19のようにまず二段目以降の引き出し本体30を強制解除して大きく開放し、一段目の引き出し本体30においては最後に下側から強制解除用突起25を押し上げる操作にて強制解除すればよい。その結果全ての位置に同じ本体装置aを用いることができるため非常に効果的である。   However, the dimensions of the protrusion of the top plate 27 in the forward direction are various, and it is not reasonable to increase the types of the main body device a. Moreover, the main body device a having a very long closing movement distance is naturally very large in the longitudinal direction, which is very inappropriate in terms of cost. Furthermore, if the closing movement distance becomes longer than necessary, acceleration and inertial force are applied to the closing position by the opening operation at the time of an earthquake, which may cause a problem in strength. However, it is an important feature that the forcible release mechanism of the present invention can perform a seesaw operation in both the up and down directions from the reference position. Therefore, the forcible release protrusion 25 can be released even if it is pushed upward from below. That is, as shown in FIG. 19, first, the second and subsequent drawer bodies 30 are forcibly released to be opened widely, and the first stage drawer body 30 is finally forcibly released by pushing up the forcible release protrusion 25 from below. That's fine. As a result, the same main device a can be used at all positions, which is very effective.

つまり受けケース19に対する係合体20の摩擦力を有しながら回転するシーソー動作においては、基準位置からの極小さい角度範囲においては自動案内機構を実施する動作になり、それ以降の大きな角度範囲においては強制解除を実施するためのものになり、1個の構成にて2個の必要動作を実施できる点が重要な特徴である。   In other words, in the seesaw operation that rotates while having the frictional force of the engagement body 20 with respect to the receiving case 19, the automatic guide mechanism is operated in a very small angle range from the reference position, and in a large angle range thereafter. An important feature is that it is for performing forced release and that two required operations can be performed with one configuration.

以上の実施形態では収納部材に引き出しを用い、さらに設置枠体である枠体内側面26に本体装置aを掘り込んだ構成にて説明してきた。しかし枠体内側面26と引き出し外側面28間の隙間が大きい場合は両者を外付けにて配置することも十分可能である。また、ここで本体装置aを掘り込んで装着する場合においては、当然掘り込みのための加工が必要になり、引き出しの左右両側に閉止装置を装着すると1個の引き出しに対して2ヵ所ずつの加工を施さなければならない。そこで掘り込み加工が単純で工数が少ない方が有利であり、木材へ加工するとすれば円形の座繰りが最も単純で安価とされている。   In the above embodiment, the description has been made with the configuration in which the drawer is used as the storage member and the main body device a is dug in the side surface 26 of the frame body that is the installation frame body. However, when the gap between the frame inner side surface 26 and the drawer outer side surface 28 is large, it is also possible to arrange both of them externally. In addition, when digging and mounting the main body device a here, it is naturally necessary to perform digging, and if a closing device is mounted on both the left and right sides of the drawer, two locations for one drawer are required. It must be processed. Therefore, it is advantageous that the digging process is simple and the man-hour is small, and if it is processed into wood, a circular countersink is the simplest and cheapest.

また、上記の実施形態では図1や図2に示すように本体ケース1の埋め込む部分の形状を、円柱座を2個横方向に重ね合わせたような形状にて表記しているが、この形状は本体装置aを装着したときに回転ずれが発生しにくいようにしたものである。それと同時に本体装置aの移動部材5が上下運動したり、転動体18が自由に動作するための内部機構はやはり略直方体のケース内に組み込む必要があり、略直方体のスペースを円柱座繰りの加工で確保するのには円柱座を二工程にて横方向に連続して掘り込むのが比較的簡単であることも要因として挙げられる。しかしこの掘り込みではどうしても二工程必要であり、さらに合理化するには一工程での掘り込みが望ましい。   In the above embodiment, as shown in FIGS. 1 and 2, the shape of the portion to be embedded in the main body case 1 is described in a shape in which two cylindrical seats are overlapped in the horizontal direction. Is designed to prevent rotational deviation when the main body device a is mounted. At the same time, the internal mechanism for moving the movable member 5 of the main body device a up and down and the rolling element 18 to move freely needs to be incorporated into a substantially rectangular parallelepiped case. The reason for this is that it is relatively easy to continuously dig a cylindrical seat in two directions in two steps. However, in this excavation, two steps are inevitably required, and excavation in one step is desirable for further rationalization.

ここで一工程での掘り込みにすると一般的には比較的大きな円形座が必要になると想定される。ところが通常枠体内側面26には図13〜図15に示すように引き出しレールが取り付けられるため、一段目の浅い引き出しに対応させるためには掘り込みのサイズを無制限に大きくすることもできない。ところが本発明の閉止装置は、本体装置aの長さ方向の寸法が非常にコンパクトに構成可能であり、上記の掘り込みに関しては非常に有利である。図20は一個の円柱座を有した本体ケース1の中央部分のみを使用した場合の本体装置aの裏面図であり、本体ケース1に同サイズの移動部材5や転動体18を組み込むことが可能である。したがってそれほど大きな円柱座での掘り込みは必要なく、一段目の浅い引き出しにも十分装着することが可能である。また多軸の加工機を用いて円柱座とボス穴を一工程で同時に加工する方法がよく、本体ケース1に円柱座とボス柱を設けておくことで回転ずれも防止でき、さらに効率の良い構成にすることができる。   Here, when dug in one step, it is generally assumed that a relatively large circular seat is required. However, since a drawer rail is attached to the side face 26 in the normal frame as shown in FIGS. 13 to 15, the size of the digging cannot be increased without limit in order to correspond to the first-stage shallow drawer. However, the closing device of the present invention can be constructed so that the size of the main body device a in the length direction is very compact, and is very advantageous with respect to the above-mentioned digging. FIG. 20 is a rear view of the main body device a when only the central portion of the main body case 1 having one cylindrical seat is used, and the movable member 5 and the rolling element 18 of the same size can be incorporated into the main body case 1. It is. Therefore, it is not necessary to dig in such a large cylindrical seat, and it is possible to install it sufficiently even in the first-stage shallow drawer. Further, it is preferable to simultaneously process the cylindrical seat and the boss hole in one step using a multi-axis processing machine, and by providing the cylindrical case and the boss column in the main body case 1, it is possible to prevent rotational deviation and further increase efficiency. Can be configured.
