The member 40, the first urging means 50 for urging the one end side of the arm 30 in the opening X direction (downward in the illustrated example), and the engagement / disengagement member 40 cannot be engaged / disengaged with respect to the opening / closing body 5. Second urging means 60 for urging in the swinging direction, and the distal end side of the engaging / disengaging member 40 is exposed to the outside of the main body case 10.

The main body case 10 is formed in a substantially rectangular parallelepiped shape according to the illustrated example, and a tool insertion hole 11 for returning the opening / closing body engaging / disengaging device 1 is formed on the lower surface thereof.
The tool insertion hole 11 is formed to have an appropriate inner diameter so that a general tapered tool such as a screwdriver can be loosely inserted. The tool insertion hole 11 communicates with an opening X formed by fully opening the opening / closing body 5 in a state where the opening / closing body engaging / disengaging device 1 is mounted on the sliding door device A.

The plunger advancing / retracting mechanism 20 is a well-known mechanism that retracts the plunger 21 by the electromagnetic force of the solenoid and advances the plunger 21 by the urging force of an urging member such as a spring. The plunger advancing / retreating mechanism 20 described later. It is arrange | positioned in the substantially horizontal shape so that it may face.
The plunger advancing / retreating mechanism 20 is configured in the control circuit of the sliding door device A so as to be activated by an emergency signal input to the sliding door device A from the outside.

A locking bracket 21 a that is locked by an arm 30 described later is provided at the tip of the plunger 21, and the locking bracket 21 a is supported so as to be slightly moved in the forward and backward direction with respect to the plunger 21.
More specifically, the locking bracket 21a receives the edge of the arm 30 biased toward the opening X direction (downward according to the illustrated example) at the most arm 30 side portion. And has a latched piece portion 21a1.
The locking bracket 21a has a long hole 21a2 that is long in the direction crossing the plunger advancing / retreating direction (vertical direction in the illustrated example), and the distal end side of the plunger 21 by the shaft member 21a3 inserted through the long hole 21a2. It is supported by.
Accordingly, the locking bracket 21a can swing around the shaft member 21a3 and can move slightly in the intersecting direction through the long hole 21a2.
With this configuration, the locking bracket 21a can move the locking piece 21a1 slightly in the advancing / retreating direction of the plunger 21 (movable), and the locking piece 21a1 intersects the plunger advancing / retreating direction. It is supported on the tip end side of the plunger 21 in a state where it can be moved slightly in the direction of movement.

  Further, according to the illustrated example, the arm 30 has a substantially inverted letter shape, and one end side facing the locking bracket 21a is locked to the locked piece portion 21a1 of the locking bracket 21a at the distal end of the plunger 21. The stop position (position shown in FIG. 3A) and the release position where the same end side is released from the locked piece 21a1 and swings in the direction of the opening X (see FIG. 3 (a)). It is pivotally supported so as to swing between the position shown in b).

The arm 30 has a pressed portion 31 for receiving a pressing force from the opening X side at a portion closer to the one end side (plunger 21 side) than the pivot portion.
According to the illustrated example, the pressed portion 31 is configured such that the lower edge portion of the one end side (plunger 21 side) of the arm 30 extends in the horizontal direction so that it can be easily pressed by a tool or the like from below. It is a part and is arranged corresponding to the position of the tool insertion hole 11 of the main body case 10.

A coil spring-shaped first urging means 50 is wound around the shaft support portion of the arm 30.
The first biasing means 50 engages the pressed portion 31 side of the arm 30 with the opening portion X by locking one end side to the pressed portion 31 of the arm 30 and locking the other end side to the main body case 10. Energizing in the direction.

  Therefore, the arm 30 is engaged when the most distal portion on the plunger 21 side (the most distal portion of the pressed portion 31 in the illustrated example) is locked to the locked piece portion 21a1 of the locking bracket 21a. The stopped state is maintained by the urging force of the first urging means 50, and when the most distal portion on the plunger 21 side is separated from the locked piece portion 21a1 of the locking bracket 21a, the pressed portion 31 is first pressed. It is swung in the direction of the opening X by the urging force of the urging means 50.

Further, the roller 32 is supported on the other end portion of the arm 30 (in other words, the end portion on the side opposite to the plunger 21) so as to roll with the outer peripheral surface abutting against an engaging / disengaging member 40 described later. .
As another example, the roller 32 may be omitted, and the other end portion of the arm 30 may be directly in sliding contact with the engaging / disengaging member 40.

  The engaging / disengaging member 40 includes an oscillating portion 41 that is engaged with the other end of the arm 30 and supported to oscillate, and an engaging / disengaging piece portion that is integrally fixed to the oscillating portion 41. 42, and is pivotally supported so as to swing between a position where it can be engaged and disengaged with respect to the opening / closing body 5 and a position where it cannot be engaged and disengaged in conjunction with the swing of the arm 30. Then, the portion of the engaging / disengaging member 40 closer to the engaging / disengaging piece portion 42 than the pivotal support portion is urged by the second urging means 60 to the position where it cannot be engaged / disengaged (upward in the illustrated example). Yes.

  The swinging part 41 has a concavo-convex part 41 a at the end of the arm 30 facing the roller 32. The concavo-convex portion 41 a is a portion formed by arranging a concave portion and a convex portion along the swinging direction on the other end side of the arm 30, and is in contact with the outer peripheral surface of the roller 32.

The operation of the uneven portion 41a will be described in detail. When the roller 32 side of the arm 30 swings in the opening X direction (downward in the illustrated example), the roller 32 is a convex portion of the uneven portion 41a. , The engagement / disengagement member 40 as a whole rotates in the clockwise direction in the drawing, and the engagement / disengagement piece portion 42 side of the engagement / disengagement member 40 opposes the urging force of the second urging means 60 in the opening X direction (see FIG. According to the example, it swings downward). Therefore, the engagement / disengagement piece 42 is in a state in which it can be engaged / disengaged with respect to the opening / closing body 5 (the state of FIG. 3A).
Further, when the roller 32 side of the arm 30 swings in the opposite opening direction (upward in the illustrated example), the engaging / disengaging piece portion 42 side of the engaging / disengaging member 40 is counteracted by the urging force of the second urging means 60. The roller 32 swings in the direction of the opening (upward in the illustrated example), and the roller 32 fits into the concave portion of the concave and convex portion 41a in the engaging / disengaging member 40. Therefore, the engagement / disengagement piece portion 42 is in a state where it cannot be engaged / disengaged with respect to the opening / closing body 5 (the state of FIG. 3B).

The engaging / disengaging piece portion 42 is a long metal member (for example, stainless steel) that can be elastically bent, and its proximal end side is fixed to the swinging portion 41 and its distal end side. A locking portion 42a is provided on the rocking end side.
The locking portion 42a is formed in a convex shape (in the illustrated example, a substantially reverse character) in the direction of the opening X, and when the entire engaging / disengaging piece portion 42 becomes substantially horizontal, It will be in the state which can be latched with respect to the latching | locking part 5a3.

  Further, according to the illustrated example, the second urging means 60 is a coil spring-like tension spring. One end side of the second urging means 60 is fixed to the main body case 10, and the other end side is an engagement / disengagement piece portion of the engagement / disengagement member 40. It is fastened to the 42 side.

Next, the effects of the sliding door device A and the opening / closing member engaging / disengaging device 1 having the above-described configuration will be described in detail.
In a normal state where no fire or the like has occurred, the opening / closing body engaging / disengaging device 1 maintains the engaging / disengaging piece portion 42 of the engaging / disengaging member 40 in a substantially horizontal state (see FIG. 3A).
This state is maintained by locking one end of the arm 30 to the locking bracket 21a at the tip of the plunger 21.
In this state, since the locking portion 42a of the engaging / disengaging piece portion 42 protrudes toward the opening X, the fully open state opening / closing body 5 is locked by the locking portion 42a. If it demonstrates in detail, the small roller 5a32 of the to-be-latched part 5a3 in the opening / closing body 5 will be latched by the latching | locking part 42a, as shown in FIG. 1, and the fully open state of the opening / closing body 5 will be maintained.

  When the external force in the closing direction is applied to the opening / closing body 5 in the state of the opening / closing body engaging / disengaging device 1 (the state shown in FIG. 3A), the engaging / disengaging piece portion 42 is locked on the opening / closing body 5 side. Since the portion 5a3 is elastically bent so as to be pushed in the direction opposite to the opening (in the illustrated example, upward), the opening / closing body 5 performs a closing operation.

Further, when an emergency signal is generated due to a fire or the like in a state where the fully open state of the opening / closing body 5 is maintained as described above, from the control circuit (not shown) of the opening / closing body 5 to the opening / closing body engaging / disengaging device 1. The plunger 21 of the plunger advance / retreat mechanism 20 is retracted by the supplied electric power.
Therefore, as shown in FIG. 3 (b), one end side (plunger 21 side) of the arm 30 swings downward, and the roller 32 on the other end side of the arm 30 is depressed in the concave / convex portion 41 a of the engagement / disengagement member 40. The engagement / disengagement member 40 swings the engagement / disengagement piece 42 side in the direction opposite to the opening (in the illustrated example, upward) by the tensile force of the second urging means 60.
Therefore, the opening / closing body 5 is released from the locked state with the engaging / disengaging piece portion 42 of the opening / closing body engaging / disengaging device 1 and automatically closes by the urging force of the urging means (not shown).

Moreover, when the opening / closing body engaging / disengaging device 1 is operated to be in the release state for operation confirmation or blame training, it is necessary to return to the normal use state.
In this case, as shown in FIG. 4B, a tapered tool y such as a screwdriver is inserted into the tool insertion hole 11 of the main body case 10, and the pressing force of the tool y causes the arm 30 to move. The pressed portion 31 is pressed in the direction opposite to the opening (in the illustrated example, upward).
Then, one end side of the arm 30 is locked to the locking bracket 21a at the tip of the plunger 21. At this time, the locking bracket 21a is slightly retracted while being in sliding contact with one end edge of the arm 30 swinging in the direction opposite to the opening (in the illustrated example, upward). Does not hinder the swinging. Therefore, the arm 30 is smoothly engaged with the one end side of the arm 30 and the engagement bracket 21a.

As described above, when one end side of the arm 30 swings in the direction opposite to the opening (upward in the illustrated example), the other end side of the arm 30 swings in the opening X direction (downward in the illustrated example). 32 is brought into contact with the convex portion of the concavo-convex portion 41 a of the engaging / disengaging member 40. At this time, the engaging / disengaging member 40 rotates in the clockwise direction in the figure against the urging force of the second urging means 60 and swings the locking portion 42a in the opening X direction.
Then, the arm 30 whose one end is swung upward is locked to the locking bracket 21a at the tip of the plunger 21, and in this locked state, the engagement / disengagement piece portion 42 is maintained in the original substantially horizontal state. The opening / closing body 5 can be engaged and disengaged at the fully opened position.

Since the returning operation using the tapered tool y described above can be performed from the opening X formed when the opening / closing body 5 is fully opened, the workability is good.
Moreover, since projections such as levers and strings for return work are not exposed to the opening X side, erroneous operations such as return by mistake can be prevented.

According to the above embodiment, the arm 30 is configured to swing in one direction by the biasing force of the first biasing means 50. However, as another example, the first biasing means 50 is omitted and the arm 30 is omitted. It is also possible to adopt a configuration that swings in the one direction only by the weight balance. That is, in the case of this mode, the weight on the plunger 21 side in the arm 30 may be set larger than the weight on the other end side.
Further, according to the above embodiment, the engagement / disengagement member 40 is swung in the direction in which the engagement / disengagement member 40 cannot be disengaged by the urging force of the second urging means 60. 40 can be swung by weight balance.

Moreover, according to the said embodiment, from a viewpoint of making workability | operativity good, the opening-and-closing body engagement / disengagement apparatus 1 is arrange | positioned near the opening part X, and the engagement / disengagement piece part 42 is latched to the suspension vehicle 5a on the door-end side. However, as another example, the engagement / disengagement piece portion 42 can be engaged with the suspension vehicle 5a on the door-end side.
