It is retracted below the position where it can be engaged. Next, when the door 50 is pushed leftward against the pulling elasticity of the pulling spring 44, the protrusion 60 moves relative to the base 4 in the right direction, that is, in one direction, and the fitting convex portion 20. , 22 relatively move along the groove 10 in the right direction (step No. 2). When the door 50 is pushed leftward, the fitting convex portion 20 of the moving member 14 is guided by the curved portion 10c of the groove 10 and is fitted into the locking portion 10b. At this time, the moving member 14 is inclined clockwise around the fitting convex portion 22, the second engaging portion 38 is retracted downward from the engaging position with the protruding portion 60, and the protruding portion 60 and the second engaging portion are moved. The engagement with the joint portion 38 is released (steps 3 and 4).

これにより、扉５０は引き込みスプリング４４の弾発力に対してフリーの状態となる。更に、扉５０を左方向に引き出すと、突起部５８は、基体４に対して右方向即ち一方向に相対移動し、左側の移動部材１２の第１係合部２６が突起部５８に衝突する（ステップ５）。なおも扉５０を左方向に押動し、突起部５８を基体４に対して右方向（一方向）に相対移動すると、この押動力により移動部材１２は、嵌合凸部１８を支点として、反時計方向に揺動する。この揺動により、第２係合部２８は、上昇して突起部５８に係合するとともに、嵌合凸部１６は、溝８の係止部分８ｂから離脱して、移動部材１２は係止状態が解除される。移動部材１２の係止状態が解除されると、第２係合部２８が引き込みスプリング４４の引っ張り弾力により突起部５８に弾接し、基体４は突起部５８を支点として、左方向に付勢される。この付勢力により、基体４は、図中、左方向に引き込まれ、突起部５８は、第２係合部２８と係合したまま、基体４に対して、右方向即ち一方向に相対移動する。 As a result, the door 50 becomes free with respect to the resilience of the retracting spring 44. Further, when the door 50 is pulled leftward, the protrusion 58 moves relative to the base 4 in the right direction, that is, in one direction, and the first engagement portion 26 of the left moving member 12 collides with the protrusion 58. (Step 5). If the door 50 is pushed leftward and the protrusion 58 is moved relative to the base 4 in the right direction (one direction), the moving member 12 uses the fitting convex portion 18 as a fulcrum by this pushing force. Swings counterclockwise. By this swinging, the second engaging portion 28 rises and engages with the protrusion 58, and the fitting convex portion 16 is disengaged from the locking portion 8 b of the groove 8, and the moving member 12 is locked. The state is released. When the locked state of the moving member 12 is released, the second engaging portion 28 comes into elastic contact with the protruding portion 58 by the pulling elasticity of the pulling spring 44, and the base body 4 is urged to the left with the protruding portion 58 as a fulcrum. The By this urging force, the base body 4 is pulled in the left direction in the figure, and the projection 58 moves relative to the base body 4 in the right direction, that is, in one direction while being engaged with the second engagement portion 28. .

これにより、扉５０は、これに対する手動による左方向の押動力を解除しても、引き込みスプリング４４の引っ張り力により、突起部５８を支点として左方向に自動的に引き込まれる（ステップ６）。嵌合凸部１８が溝８の右側終端近傍に達すると、扉５０は、その左側面が左側突き当て部５６に弾接し、これに係止される（ステップ７）。これによって、支持体４６の戸口は、扉５０によって完全に閉じられ、扉５０は、支持体４６の左側の移動端に閉止される。扉５０を右方向に引き出す場合は、上記ステップＮｏ．１〜７とは逆のステップＮｏ．７〜１の動作となる。即ち、図１０において、扉５０が左側閉止位置から右方向に引き出されると、突起部５８は、基体４に対して、左方向即ち他方向に相対移動し、移動部材１２は、突起部５８との係合が解除され、移動部材１２は、溝８の係止部分８ｂに係止される。更に扉５０を右方向に引き出すと、図１０のステップ１で移動部材３が突起部６０と係合する。 Thereby, even if the manual leftward pushing force is released, the door 50 is automatically pulled leftward by the pulling force of the pulling spring 44 (step 6). When the fitting convex portion 18 reaches the vicinity of the right end of the groove 8, the left side of the door 50 comes into elastic contact with the left abutting portion 56 and is locked thereto (step 7). As a result, the door of the support 46 is completely closed by the door 50, and the door 50 is closed to the moving end on the left side of the support 46. When pulling out the door 50 in the right direction, the above step no. Step No. 1 opposite to steps 1-7. The operation is 7-1. That is, in FIG. 10, when the door 50 is pulled rightward from the left side closed position, the protrusion 58 moves relative to the base 4 in the left direction, that is, in the other direction, and the moving member 12 Is released, and the moving member 12 is locked to the locking portion 8 b of the groove 8. When the door 50 is further pulled out to the right, the moving member 3 engages with the protrusion 60 in step 1 of FIG.

なおも扉５０を右方向に手動で引き出すと、突起部６０は、基体４に対して、左方向即ち他方向に相対移動し、移動部材１４の係止状態が解除され、移動部材１４に突起部６０を支点として引き込みスプリング４４の引っ張り力が作用し、扉５０は、この引き込みスプリング４４の引っ張り力によって自動的に右方向に引き込まれる（図１０のステップ２）。嵌合凸部２２が溝１０の左側近傍に達すると、扉５０の右側面は、右側突き当て部５４に弾接し、戸口が完全に開き、扉５０は開方向側の突き当て部５４に閉止される（図１０のステップ３）。尚、図９のステップ１及びステップ５に示すように、扉５０が突き当て部５４又は５６に移動している状態では、移動部材１２，１４は溝８，１０の係止部分８ｂ，１０ｂによって係止されている状態が正常であるが何らかのアクシデントにより、移動部材１２，１４が係止部分８ｂ，１０ｂから外れ、溝８，１０の直線部分８ａ，１０ａの端部に移動している場合が生じることがある。 When the door 50 is manually pulled out in the right direction, the protrusion 60 moves relative to the base 4 in the left direction, that is, in the other direction, the locked state of the moving member 14 is released, and the protruding portion 60 protrudes from the moving member 14. The pulling force of the pulling spring 44 acts on the portion 60 as a fulcrum, and the door 50 is automatically pulled rightward by the pulling force of the pulling spring 44 (step 2 in FIG. 10). When the fitting convex portion 22 reaches the vicinity of the left side of the groove 10, the right side surface of the door 50 comes into elastic contact with the right abutment portion 54, the door is completely opened, and the door 50 is closed to the abutment portion 54 on the opening direction side. (Step 3 in FIG. 10). As shown in Step 1 and Step 5 of FIG. 9, when the door 50 is moved to the abutting portion 54 or 56, the moving members 12 and 14 are moved by the locking portions 8 b and 10 b of the grooves 8 and 10. Although the locked state is normal, the moving members 12 and 14 may be disengaged from the locking portions 8b and 10b and moved to the end portions of the straight portions 8a and 10a of the grooves 8 and 10 due to some accident. May occur.

この場合には、移動部材１２，１４を定常位置に戻しておく必要がある。非常用係合部材３０，４０は、この場合の救済手段として設けられている。移動部材１２を定常位置に戻す動作について説明すると、まず、引き出し扉５０を閉める方向即ち左方向に手作業により押動し、突起部５８を、基体４に対して右方向即ち一方向に相対移動させ、非常用係合部材３０の傾斜面３０ｂに衝突させる。なおも、扉５０を左方向に押動すると、突起部５８により、係合部材３０は、ばね部３０ａの弾力に抗して、基体４から引っ込む方向に変位する。 In this case, it is necessary to return the moving members 12 and 14 to their steady positions. The emergency engagement members 30 and 40 are provided as rescue means in this case. The operation of returning the moving member 12 to the steady position will be described. First, the drawer door 50 is pushed by hand in the closing direction, that is, the left direction, and the protrusion 58 is moved relative to the base 4 in the right direction, that is, in one direction. And is made to collide with the inclined surface 30b of the emergency engagement member 30. In addition, when the door 50 is pushed leftward, the engaging member 30 is displaced by the protrusion 58 in the direction in which it is retracted from the base body 4 against the elasticity of the spring portion 30a.

突起部５８が傾斜面３０ｂを乗り越えると、非常用係合部材３０は、元位置にばね部３０ａの弾力で復帰し、突起部５８は、第３の係合部３２と第２の係合部２８との間に嵌入し、突起部５８は、係合部３２，２８間にチャックされる次に、扉５０を右方向に手操作で引き込みスプリング４４の弾力に抗して引くと、突起部５８は、基体４に対して左方向即ち他方向に相対移動し、移動部材１２が溝８ａに沿って、左方向に移動し、扉５０が右側突き当て部５４に達したところで、嵌合凸部１６が、溝８の係止部分８ｂに嵌入して、移動部材１２は、定常位置に戻り、該位置に係止される。このとき非常用係合部材３０は、基体４から引っ込み突起部５８との係合可能位置から外れる。移動部材１４を定常位置に戻す動作も、上記移動部材１２で説明した動作と原理は同一であるのでその説明を省略する。 When the protruding portion 58 gets over the inclined surface 30b, the emergency engaging member 30 returns to the original position by the elasticity of the spring portion 30a, and the protruding portion 58 has the third engaging portion 32 and the second engaging portion. 28, and the projection 58 is chucked between the engagement portions 32 and 28. Next, when the door 50 is manually pulled in the right direction and pulled against the elasticity of the spring 44, the projection 58 moves relative to the base 4 in the left direction, that is, in the other direction, the moving member 12 moves in the left direction along the groove 8a, and the door 50 reaches the right abutting portion 54. The portion 16 is fitted into the locking portion 8b of the groove 8, and the moving member 12 returns to the steady position and is locked at the position. At this time, the emergency engagement member 30 is disengaged from the position where it can engage with the retracting protrusion 58 from the base 4. The operation for returning the moving member 14 to the steady position is the same as the operation described for the moving member 12, and the description thereof is omitted.
