[Prior art and problems to be solved by the invention] Conventionally, sliding doors and other doors equipped with a self-closing mechanism begin to close as soon as they release their hands from the open position, which makes it difficult for people who are carrying luggage or who are in a wheelchair to close the doors. When passing through a vehicle, etc., when it takes time to pass, it is inconvenient to have to hold down the door as it starts to close or open it again. In particular, it takes time for people in wheelchairs to pass through hospitals, rehabilitation facilities, etc., reducing safety. Also, if the closing force is too strong when the door closes, the door will hit the door frame with force, making a loud noise and causing the door to bounce back, which can be avoided. In order to do this, it is necessary to hold the door body in a state where it does not receive impact.

Therefore, we decided to make the door automatically open and close electrically.
There are known devices that delay the opening and closing of the door, but because they are powered by electricity, they are expensive and have a complicated mechanism. Therefore, attempts were made to delay the operation by using components such as cylinders and holders without electric power, and this was achieved in practice.
An application for utility model registration was filed as No. 55-84860 (Publication No. 57-16480), thereby delaying the operation at the start of closing and at the end of opening without using electrical means. However, since the cylinder is oriented vertically, this type requires a long installation space in the vertical direction, and as a result, a long installation space in the vertical direction is required for the vertical frame of the door body. We will have no choice but to ensure that. However, in this case, the control valve that adjusts the expansion and contraction operation time of the cylinder faces the bottom of the installation space, contrary to the upwardly protruding cylinder shaft, so in order to perform adjustment work, Since the cylinders have to be taken out one by one, there is a problem in that work efficiency is significantly degraded during maintenance.

Next, the operation of the embodiment of the present invention constructed as described above will be explained. When the sliding door 1 in the closed state is opened, the wife 8 is rolled out one after another against the bullet 10, but just before the sliding door 1 touches the vertical frame on the bottom side of the door, the tip of the operating arm 13 in the fallen position is captured. body 14
is captured and fitted into the holding body 15, and the operating arm 13 assumes an upright position. That is, when the captured object 14 comes into contact with the holding body 15 due to the opening force of the sliding door 1, an upward rotational moment is applied to the operating arm 13 about the support shaft 13a, and the cylinder shaft 12c is extended. In conjunction with this, the actuating arm 13 sequentially stands up, and the captured object 14 gradually fits into the holding body 15. The sliding door 1 opens in a state in which the impact when the door is opened is absorbed and bounce is prevented.

The sliding door 1 that has been opened in this manner immediately tries to start closing due to the restoring force of the ammunition 10 that has been stored as a result of the wire 8 being fed out.
However, since the captured object 14 is captured and fitted to the holding body 15, the captured object 14 is captured and fitted to the holding body 15.
While the sliding door 1 is released, the sliding door 1 does not immediately start its closing operation, but remains in the open position for a while. Then, when the captured object 14 is released from the holding body 15, the sliding door 1 starts closing operation by the self-closing mechanism 6.

In this way, the start of the door closing operation is delayed until the captured object 14 is released from the holding body 15, but this delay time is determined by rotating the control valve 12b according to the on-site requirements. can be dynamically adjusted and changed. To do this, remove the inspection cover 18 on the frame and do it from the upper opening of the mounting bracket 11, or remove the edge material 16 and do it from the outside in the left and right direction of the mounting bracket 11. This can be done without removing the cylinder 12 one by one.

That is, the cylinder 12 is disposed in the mounting bracket 11, which is open at the upper and outer sides in the left-right direction, in a horizontal position with the regulating valve 12b facing outward in the left-right direction. Therefore, the delay time of the cylinder 12 can be adjusted from the upper side of the mounting bracket 11 and from the outer side in the left and right direction, and there is no need to remove the cylinder 12 each time as in the past. It is possible to make adjustments in the same state as it is, and maintainability is significantly improved.

Furthermore, in this device, the actuating arm 13 is arranged in a substantially inverted L shape within the mounting bracket 11.
A dead space surrounded by a distal arm piece facing in the left-right direction and a proximal arm piece extending downward from the distal arm piece is effectively used as a mounting gap for the cylinder 12 facing in the horizontal direction. The pivot position 13a of the proximal arm piece relative to the mounting bracket 11 is the pivot position 13b of the proximal arm piece relative to the cylinder rod 12c.
It is located on the bottom side of the groove of the mounting bracket 11. Therefore, the cylinder 12 is
The arrangement is such that the actuating arm 13 and the cylinder 12 can be installed in a state that fits almost within the installation space of the actuating arm 13, and the actuating arm 13 and cylinder 12 can be arranged compactly not only in the vertical direction but also in the horizontal direction. This eliminates the need for a large mounting space, which would be caused by a long cylinder in the vertical direction, such as in a case where cylinders are arranged vertically and an operating arm is arranged above the cylinder, and the mounting bracket 11 can be made large and vertical. This means that it can be installed without having to deeply install it into the frame or upper frame.

[Operation and Effect] In summary, since the present invention is constructed as described above, when the door body starts closing operation from a fully open state, there is a delay only while the captured object is released from the holding body. However, the cylinder is
The control valve is disposed in a horizontal position facing outward in the left-right direction in a mounting bracket that is open upward and outward in the left-right direction. Therefore, the cylinder delay time adjustment work can be done from the top of the mounting bracket and from the outside in the left and right direction, and the cylinder can be installed without having to remove the sliding door from the rail and pull out the cylinder one by one as in the past. Since adjustments can be made while it is attached to the bracket, ease of maintenance is significantly improved.

Moreover, the actuation arm to which the captured object is attached has a substantially inverted L shape, and the dead space surrounded by the upper distal arm piece and the proximal arm piece on one side can be effectively utilized. A cylinder facing the left and right horizontal direction is accommodated here, and the pivot position of the proximal arm piece relative to the mounting bracket is lower than the pivot position of the proximal arm piece relative to the cylinder rod, and the mounting As a result of being located at the bottom of the groove of the bracket, the cylinder can be installed in a compact manner, fitting almost within the installation space of the actuating arm. Unlike the case where the cylinder and the actuating arm are arranged vertically, the cylinder and the actuating arm do not have to be arranged long in the vertical direction, and it is possible to install the cylinder in a compact manner within the installation space of the actuating arm.

A cylinder that is pivotably supported vertically on the upper frame side of a self-closing door body that is equipped with a self-closing mechanism that automatically closes the door body that is opened in the left and right direction;
An operating arm that is pivotally supported on the upper frame of the door body so as to be able to swing up and down, is pivotally connected to the tip of a cylinder shaft, and swings as the cylinder shaft expands and contracts; and a captured target that is attached to the tip of the operating arm. At the same time, a holding body is integrally attached to the opening frame side in order to capture and fit the captured object based on the swing of the actuating arm as the cylinder shaft expands and contracts, thereby delaying the opening/closing operation of the door body. In the self-closing door holding device, the cylinder is of an adjustable type, in which a cylinder shaft that is telescopically operated protrudes from one side, and a control valve that can adjust the telescoping operation time of the cylinder shaft is provided on the other side. The cylinder is placed in a mounting bracket integrally formed at the left and right ends of the upper frame, with the cylinder shaft facing inward of the door body, and the cylinder axis facing the inside of the door. The valve is installed in a horizontal position facing the outside of the door body, and the actuating arm includes a proximal arm piece facing up and down and a distal arm piece bent from the upper end in the left-right direction. The proximal arm piece has an approximately inverted L shape, and the intermediate part of the proximal arm piece is mounted on the tip of the cylinder shaft, and the lower end is supported between both side walls of the bottom side of the groove of the bracket. A holding device for a self-closing door body, characterized in that a distal arm piece to be attached is arranged to protrude upward from an opening edge of a mounting bracket located directly above a cylinder.
