This invention relates to a sliding door stopper mechanism for a sliding door that makes it impossible to open beyond a predetermined opening width from the indoor side when performing so-called "left opening".

[Conventional technology]

For example, in a nursing home, you may want to leave the sliding door open to a certain extent without a caregiver present to prevent patients from going outside, or in a home with infants, if the infant leaves alone Leaving the door behind is required in situations where you want to ensure ventilation while preventing people from getting out, and in situations where you want to prevent sliding doors from opening beyond a certain width in high-rise buildings for safety measures such as suicide prevention. There is.

Normally, the expected width of the remaining width is approximately 5 to 20 cm, but from the standpoint of those who install this type of residual width stopper, it is easy to set the remaining width from the indoor side.
It must be difficult for patients, infants, outsiders, etc. to release the system.It must be possible to release the system easily from the outside in the event of an emergency such as a fire.These items must be implemented in a simple and trouble-free structure. What is required is something that can be achieved with

[The problem that the idea aims to solve]

By the way, conventional stoppers for leaving behind are installed either on the indoor side or the outdoor side,
If the system was left in place, it could only be canceled by the person who set it up, and it was not possible to specifically address the above-mentioned request.

[Means to solve the problem]

Here, this invention includes a rotary stopper mechanism provided on the outdoor side of the lower stile of the sliding door along the rising edge material of the lower stile, a stopper arm circumscribed and rotatably supported on the lower stile, and a stopper arm rotatably supported on the lower stile. It consists of a socket bolt that is inserted into the stopper arm from the indoor side through the lower stile, and a fixing bolt that is screwed into the socket bolt from the outdoor side. A tilting pin fitting part is provided for removably fitting the tilting pin, and a lower frame fixing member is provided on the lower frame rising edge material to work with the stopper arm to enable the sliding door to remain in place.

In addition, the present invention proposes a remaining stopper mechanism for a sliding door in which an auxiliary stopper for preventing rotation of the stopper arm at this time is attached to the lower stile.

[Effect]

In the mechanism of this invention with the above configuration, it is made impossible to release the remaining part from the indoor side unless a specific stopper raising/tilting tool is used, but it is made extremely easy to release the remaining part from the outdoor side. This makes it possible to enter the room without any problems in the event of an emergency.

〔Example〕

Next, this invention will be explained in detail with reference to the drawings. Although the illustrated embodiment shows a case in which the mechanism of this invention is disposed on the right side of the lower stile, it is of course possible to adopt a mode in which it is disposed on the left side as appropriate.

First, in Figures 1 and 2, 1 is the lower stile of the sliding door, and this lower stile 1 is the lower frame 2 of the building frame.
It opens and closes when guided by the A rotation stopper mechanism part 3 is provided on the outdoor side of the lower stile 1 along the rising edge material 2a of the lower frame 2, and this rotation stopper mechanism part 3 is rotatable by circumscribing the lower stile 1. A stopper arm 4 supported, a socket bolt 5 inserted into the stopper arm 4 from the indoor side through the lower stile 1, and a fixing bolt 6 screwed into the socket bolt 5 from the outdoor side.
At the same time, a tilting pin fitting portion 9 is provided on the indoor end surface of the socket bolt 5 for detachably fitting the tilting pin 8 of the stopper tilting tool 7. In this case, if the tilting pin 8 and the tilting pin fitting part 9 have a special shape, the purpose of this invention can be better met. Note that 10 is a knock pin for integrating the stopper arm 4, socket bolt 5, and fixing bolt 6.

On the other hand, on the rising edge material 2a of the lower frame 2, a fixed stopper 11 for the lower frame is fixed with screws 12 in cooperation with the stopper arm 4 of the rotation stopper mechanism 3 to enable the sliding door to remain in its original position. Further, an auxiliary stopper 13 is attached to the lower frame 1 on the opposite side of the lower frame fixed stopper 11 with the stopper arm 4 in between.
In this case, the stopper arm 4 is the fixed stopper 11 for the lower frame.
It has the function of preventing the stopper arm 4 from swinging when the door is hit, and as shown in FIG.
The stopper arm 4 is rotated in the direction of arrow F from the resting position and used as a catch. In order to stably support the stopper arm 4, the upper surface of the auxiliary stopper 13 is provided with a It is appropriate to provide a downwardly inclined surface 14.

Note that the auxiliary stopper 13 may be replaced with one having a structure similar to the steady rest pin 16 mechanism described later.

In the above configuration, when an attempt is made to open the sliding door, the stopper arm 4 of the rotating stopper mechanism 3 of the lower stile 1 of the sliding door hits the fixed stopper 11 for the lower frame attached to the rising edge material 2a of the lower frame 2. This is done by pulling the sliding door in the closing direction from the outdoor side, rotating the stopper arm 4 in the direction of arrow F, and pushing the auxiliary stopper. By placing the device on the stopper 13, it is possible to easily release the left behind. , it is impossible to release the remaining balance.

FIG. 4 shows an example in which the remaining width can be adjusted in several steps or continuously.
A large number of screw holes 15 are drilled for installation in step 2, and if these screw holes 15 are opened continuously according to the screw spacing, it will be possible to almost steplessly remove any remaining residue. The length L is adjustable.

5 and 6 a and b show a steady rest pin 1 attached to the lower frame 1 adjacent to the stopper arm 4 in order to complement the function of the fixed stopper 11 for the lower frame.
6 and a mechanism for advancing and retracting this pin 16, in which a cylindrical body 17 is attached that penetrates the lower stile 1 from the indoor side to the outdoor side and has flanges 17a and 17b formed at both ends, A pin 16 protruding toward the outdoor side is inserted into this cylindrical body 17, and the stepped portion 18 touches the flange 17b, thereby restricting the amount of protrusion toward the outdoor side. The tip end 21 of the pusher 22 is inserted into the section 20, and the proximal end 23 of the pusher 22 has a flat long groove 24 on its end face facing toward the indoor side.
In addition, the hollow part 20 is provided with a U-shaped groove 26 as shown in FIG. A fitting protrusion 27 that engages with this groove 26 is provided in a protruding manner, and the tube is further inserted into the cylinder via a long groove 17c in the circumferential direction formed in the cylindrical body 17 and a long groove 28 in the axial direction formed in the hollow part 20. A screw 29 is screwed in from the outer periphery of the shaped body 17 toward the pusher 22, and the length of the long groove 28 is approximately equal to the length of the straight part 26a of the U-shaped groove 26, and Its width is approximately equal to the width through which the fitting protrusion 27 can move in the circumferential direction toward the locking portions 26b, 26c of the groove 26. A spring 3 is provided between the flange 30 loosely fitted in the middle of the pusher 22 and the flange 17a on the indoor side of the cylindrical body 17.
1, elastic force is applied to the pin 16 through the hollow part 20 so that it always occupies the protruding position. In order to move to the position, a flat actuator 32 provided at the opposite end of the stopper raising/lowering tool 7 where the tilting pin 8 is formed as shown in FIG. 1 is inserted into the long groove 24. The fitting protrusion 27 is inserted and rotated by 90 degrees so as to be engaged with the long groove 25, and the fitting protrusion 27 is released from the locking part 26b as shown in FIG. By moving to the locking part 26c,
The pin 16 is made to protrude to prevent the stopper arm 4 from rotating. To release it, grasp the pin 16 from the outdoor side, rotate it to move the fitting protrusion 27 from the locking part 26c to the straight part 26a, and then push the pin 16 against the force of the spring 31 to release the pin 16. Rotate and engage the fitting protrusion 27 in the locking portion 26b.
All you have to do is lock it. In this case, the stopper arm 4 has a notch 4 at such a depth that rotation in the F direction is not prevented by the flange 17b or the like.
