The first end of the first link arm (21) is brought into contact with the inner wall surface of the rear side, and the other end of the first link arm (21) is disregarded toward the tip end side in the vicinity of the bent portion of the first link arm (21). It is urged in a direction to project from the window hole (20a) of 20), that is, clockwise. The elastic force of the spring (25) causes the door (D ₁ ) biased in the closing direction by an automatic closing device (not shown) to move the first arm (21) to the hollow case (20).
It is set to be smaller than the force to rotate inward.

The link rod (26) connects the rear end portions of the first and second link arms (21) (22) to the pin shafts (30) (3), respectively.
1) is swingably connected, and the length between the pin shafts (30) (31) of the link rod (26) is equal to the length between the pivot shafts (28) (29). is there. Therefore, the link rod (26) causes the first and second link arms (21, 22) to oscillate in the same direction and in the same angle in synchronization with each other in a state where the corresponding portions are kept parallel to each other. It has been connected.

The stopper (27) has a cylindrical head portion (27a) and a screw portion (27) formed integrally with the head portion (27a).
b) and on the rear side of the base block (32) disposed inside the right side of the hollow case (20) along the longitudinal direction of the hollow case (20) with the screw part (27b). It is screwed. A cylindrical lock nut (33) is screwed into the screw portion (27b), and the head portion (27a) of the stopper (27) and the lock nut (33) are screwed.
Round holes (27c) (33c) formed in appropriate numbers on the sides of the

By changing the contact position with the rear end, the projecting angle of the first and second link arms (21, 22) from the hollow case (20) is adjusted.

The door closing order adjusting device having the above configuration is attached to the upper frame (K) in the state adjusted as follows.

That is, the roller (2) at the tip of the first link arm (21) is
The angle θ ₁ formed by the first link arm (21) and the door (D ₁ ) at the time when the door (D ₁ ) having no combination (m) abuts on 3) is the second link arm (22). ) Smaller than the angle θ ₂ formed by the second link arm (22) and the door (D ₂ ) at the time when the door (D ₂ ) with the assembly (m) comes into contact with the roller (24) at the end of Moreover, the protrusion amount of the stopper (27) from the stopper base block (32) is adjusted so that the angle θ ₁ becomes an acute angle. Therefore,
Since the angle θ ₁ formed by the first link arm (21) and the door (D ₁ ) is an acute angle smaller than the angle θ ₂ formed by the second link arm (22) and the door (D ₂ ), First
The force that the link arm (21) receives from the door (D ₁ ) to rotate in the counterclockwise direction, that is, the force that acts to retract the first link arm (21) is the second link arm (22). It is set to be larger than the force received from (D ₂ ). Furthermore, the stopper (27) prevents the second link arm (22) from retracting against the spring (25) by the door (D ₂ ) biased in the closing direction by an automatic closing device (not shown). Adjust the protrusion amount of.

The operation of the door closing order adjusting device having the above configuration will be described below.

First, the door (D ₁ ) without the meeting (m) is the meeting (m)
When the door (D ₂ ) attached with the door is closed before coming into contact with the roller (23) at the tip of the first link arm (21), as described above, the first link arm (21) and the door (D ₁ ). because) the angle theta ₁ with is an acute angle, to the door (D ₁₎ closing direction with the urging by the self-closing device (not shown) is rotated counterclockwise to the first link arm (21) Acting,
The first link arm (21) is rotated toward the inside of the hollow case (20) against the elastic force of the spring (25) and retracted. The withdrawal operation of the first link arm (21) is transmitted to the second link arm (22) via the link rod (26), so that the second link arm (22) is moved to the first link arm (21). ), It rotates in the same direction and retreats into the hollow case (20).

Therefore, since the second link arm (22) withdraws, the door (D ₂ ) with the assembling (m) smoothly receives no resistance by the urging force of the automatic closing device (not shown). Close the door.

Next, the door (D ₂ ) with the meeting (m) is the meeting (m)
When the door (D ₁ ) is closed before the door (D ₁ ) and comes into contact with the roller (24) at the tip of the second link arm (22), as described above, the door (D ₂ ) moves to the second link arm ( twenty two)
It is stopped and held at the front position of the door that is in contact with the tip of the. Then, the door (D ₁ ) without the above-mentioned combination (m) is rotated in the closing direction by an automatic closing device (not shown), and the door (D ₁ ) is rotated.
_{When 1} ) comes into contact with the roller (23) at the tip of the first link arm (21), the first link arm (21) is placed in the hollow case (20) against the elastic force of the spring (25) as described above. Rotate inward and retract.

As described above, the angle θ ₁ formed by the first link arm (21) and the door (D ₁ ) is equal to the second link arm (2
2) because that is the acute angle less than the angle theta ₂ of the door _{(D 2),} from the rotation center _{C 1} of the door _{(D 1)} first
The distance from the contact point of the link arm (21) to the roller (23) is greater than the distance from the rotation center C ₂ of the door (D ₂ ) to the contact point of the roller (24) of the second link arm (22). It's getting longer. Therefore, after the door (D ₁ ) contacts the roller (23) of the first link arm (21), the door (D ₁ ) is closed more than the door (D ₂ ). The first link arm (21) retracts into the hollow case (20) by closing the door (D ₁ ), and retracts into the hollow case (20) in synchronization with this operation via the link rod (26). By the second link arm (22), the door (D ₂ ) follows the door (D ₁ ) and closes in a regular order.

That is, according to the door closing order adjusting device of the present invention, when the two doors (D ₁ ) and (D ₂ ) are closed in the regular order, the roller at the tip of one of the first link arms (21) is (twenty three)
Contact only the door (D ₁ ), and the doors (D ₁ ) (D ₂ ) are closed in the reverse order, the respective doors (D ₁ ) (D ₂ ) and the first and _second doors are closed. Link arm (21)
Due to the difference between the angles θ ₁ and θ ₂ formed by (22) and the door (D
₁ ) (D ₂ ) are the first and second link arms (21) (22)
The force acting to retract the inside of the hollow case (20) and the doors (D ₁ ) (D ₂ ) cause the rollers (23) (at the tips of the first and second link arms (21) (22)). 24) By changing the contact position to the door (D ₁ )
In order to control (D ₂ ) to the regular closing order, the first and second
As the spring (25) for projecting the link arms (21, 22) from the hollow case (20), one having a weak elastic force can be used.

Therefore, according to the door closing order adjusting device of the present invention, unnecessary contact between the door and each roller of the first link arm and the second link arm is eliminated, and the contact force between the door and the roller is small. Therefore, the door is prevented from being damaged.

In addition, in the above-mentioned embodiment, the present invention is applied to the one in which the right side door is formed, but when it is applied to the one in which the left side door is formed, the order adjusting device is turned over and attached to the upper frame. Just do it.

As described above, according to the door closing order adjusting device of the present invention, when the two doors with double doors are closed in the normal order, the first link arm is retracted by the door that is not closed first. At the same time, the second link arm connected to the link arm by the link rod retreats in synchronization with the first link arm.
When the doors are closed without coming into contact with the rollers of the second link arm and the doors are to be closed in the reverse order, the first link arm may differ due to the difference in angle formed between each door and the first and second link arms. A slight biasing force of the spring applied from the link rod prevents the door of the door with a summon from being closed, and the retracting movement of the first link arm caused by the closing operation of the door without a summon is followed by the second movement. Since the second link arm is closed by retracting the link arm, unnecessary contact and rubbing with the door can be prevented, and damage to the door and peeling of the paint can be prevented. Since a sliding member such as
It has a simple structure, can be downsized, and has high durability.

Therefore, according to the present invention, it is possible to provide a door closing order adjusting device which is small in size and light in weight and which is capable of effectively preventing damage to a door and which is extremely highly practical.
