[0011]
As described above, the door closing order adjuster 1 having the above-described structure has the base 4 fixed to the upper frame 2 of the building by screws 3, and in this state, the rotating arm 6 projects forward from the upper frame 2 by the coil spring 8. . In the double door, the inner surface of the end of the other door 20 on the side plate 20a side rotates when the other door 20 on the rear closing side tries to close first with respect to the one door 19 on the front closing side. Even if a force in the closing direction is applied to the other door 20 by an automatic door closing device such as a door closer provided on the other door 20 side in contact with the roller 12 at the other end of the arm 6, the other door 20 is closed. Is temporarily stopped. In other words, the other door 20 is temporarily stopped halfway unless the pivot arm 6 acts as a stick and pushes the pivot arm 6 down. In this state, when one door 19 closes and the contact surface between the inner surface of the other door 20 on the side plate 20a side and the roller 12 on the other end of the rotating arm 6 is exceeded, the eyes of the one door 19 The coil spring 8 is moved from one door 19 to the rotating arm 6 by a force in the closing direction by a door automatic closing device such as a door closer provided on the one door 19 side with the front end of the plate 19a contacting the front surface of the rotating arm 6. The force is transmitted in a direction in which the rotating arm 6 is rotated in a straight line (180 degrees) with the base 4 against the urging force. As a result, the tension force of the other door 20 is released by the rotating arm 6, the other door 20 is closed after the one door 19, and finally the door is closed as shown in FIG. 7.
[0012]
By the way, the protrusion angle of the rotation arm 6 with respect to the base portion 4 varies depending on the size of the door, and the other door 20 closes and contacts the roller 12 at the other end of the rotation arm 6. Must be 90 degrees (right angle) to the inner surface of 20. In order to perform such angle adjustment, as described above, in the present embodiment, the angle adjusting screw 10 is screwed into the female screw portion 9a of the bracket 9 and the female screw portion 14a of the female screw member 14 continuous to the female screw portion 9a. The screwing amount of the angle adjusting screw 10 with respect to the female screw portion 14a of the female screw portion 14a of the female screw portion 9a and the female screw member 14 continuous to the female screw portion 9a is set to the -groove 10a 'of the head portion 10a or the -groove 10b' of the tip portion 10b. The position of the head 10 a is determined by engaging the adjusting jig and turning the angle adjusting screw 10, and the tip 7 a of the lever block 7 built in one end side of the rotating arm 6 is moved to the angle adjusting screw 10. The head 10a can be brought into contact with the head at an accurate angle. This angle adjustment operation is performed on either of the head 10a facing the front of the angle adjustment screw 10 and the −grooves 10a ′ and 10b ′ for engaging the adjustment jig formed on the tip 10b facing the rear of the angle adjustment screw 10. By engaging the adjusting jig, it can be performed from any direction.
[0013]
Further, in the present embodiment, as described above, the head 16a of the screw 16 provided so as to protrude forward of the lever block 7 is covered with the sheet-like cover 17 from the front, and the screw 16 protrudes from the lever block 7. The head 16 a can be brought into contact with the inner surface of the eye plate 19 a of the one door 19 through the sheet-like cover 17 in a state where the amount is adjusted and the one door 19 on the closed side is closed. Thus, when the one door 19 is closed, the head 16a of the screw 16 contacts the inner surface of the eye plate 19a of the one door 19 via the sheet-like cover 17, so that the rotating arm 6 is in contact with the base 4. Thus, the roller 12 at the other end of the rotating arm 6 does not hit the inner surface of the other door 20 even when the other door 20 on the rear closing side is closed. Therefore, when only the other door 20 opens and closes while one door 19 is closed, the pivot arm 6 is supported by the one door 19 so that it does not swing, and the rotation with the opening of the other door 20 occurs. It is possible to prevent the generation of a collision sound due to a collision between the moving arm 6 and one door 19.
[0014]
In the door closing order adjuster 1 of the embodiment described above, the tip end portion 7a of the lever block 7 built in one end side of the rotating arm 6 comes into contact with the head portion 10a of the angle adjusting screw 10. However, without providing the lever block 7, the plate portion on one end side of the rotating arm 6 is partially extended so that the tip of the plate portion is brought into direct contact with the head portion 10 a of the angle adjusting screw 10. Also good. Further, the angle adjustment screw 10 is screwed into the angle adjustment screw attachment member composed of two parts, the bracket 9 and the female screw member 14, but the specific configuration of the angle adjustment screw attachment member is limited to that shown in the drawings. In short, what is necessary is just to have a function of screwing and attaching the angle adjusting screw 10.
