DETAILED DESCRIPTION OF THE INVENTION The present invention locks a hinged door only in a predetermined open position.
The present invention relates to the opening/closing device for a hinged door, which is equipped with an opening position regulating device that automatically fixes the position of the hinged door during the opening operation of the hinged door.

Conventionally, the above-mentioned opening position restricting device has been attached between the lower stile of the hinged door and the lower frame of the window. That is, as shown in FIGS. 1 and 2, when attaching the hinged door 1 to the window frame 2, insert the hinge 3 between the corresponding vertical stile 1a and vertical frame 2a of the hinged door 1 and the window frame 2. Installed, in this state, open the hinged door 1
A certain gap 4 is formed between the lower frame 1b of the lower frame 1b and the lower frame 2b of the window frame 2-. As is well-known, there is a tendency for the value to gradually decrease due to On the other hand, the opening position regulating device 5 uses this gap rllll14 to prevent the hinged door from opening due to the handling procedure.
was installed at the bottom of the. Further, a crescent (not shown) for locking the window when the window is closed is attached to a vertical stile (not shown) on the open side of the hinged door 1.

Here, the specific structure and operation of the open position restricting device 5 will be explained.
The lever 7 includes a lever 7 which is swingably attached to the lever 7, and an actuation pin 9 which is loosely inserted into both the free end of the lever 7 and a guide hole 8 formed in the guide fitting 6. Specifically, the lever 7 has a guide fitting 8b, and the base end of the lever 7 is swingably supported by a pin 11 on a mounting fitting 10 fixed to the lower frame 2b. Also, 1 operating pin, 9 pieces.

It can be fitted into and removed from the bulging holes 8a and 8b.

In addition, there is a large diameter portion 9 that cannot be fitted into the guide hole 8 other than the bulging hole portions 8a and 8b (hereinafter referred to as narrow portion 8C).
a, and a small diameter portion 9b that can be freely fitted into and removed from the narrow portion 8C. Then, the sliding shaft 12 is fitted onto the small diameter portion 9b by inserting the flat plate portion 6a of the guide fitting 6 between the large diameter portion 9a and the sliding shaft 12, and the sliding wheel weight 2 is transferred to the flat plate portion 6a. A spiral spring 13 that presses against the back surface is fitted and held on the outside. In addition, the fall prevention flange of 141d spiral gene 13,
15 is a flange for preventing the operating pin from falling off.

With this configuration, the lever 7 is attached to the window lower frame 2b in a manner eccentric to the first hinge 3, that is, the center of swing when the hinged door 1 is opened and closed. Therefore, as is clear from FIG. 2, when the hinged door 1 in the rA chain state is opened outward, the operating pin 9
The small diameter portion 9b is guided by the narrow portion 8C of the guide hole 8 and slides toward one end thereof, and at the same time, the lever 7 swings about the pin 11. When the opening angle of the hinged door 1 reaches, for example, 5 degrees, the actuating pin 9 reaches the bulging hole 8a in the center of the guide hole 8, as shown by the dashed line in FIG. The large diameter portion 9a fits into the bulging hole 8δ, and the hinged door 1 is locked in this position. Next, to open the hinged door 1 further,
First, by pushing the lever 7 by hand, the operating pin 9 is pushed down through the lever 7 against the bias of the spiral spring 13, and the large diameter portion 9a is pulled out from the bulging hole 8a. After that, it is necessary to reopen the hinged door 1. As a result, the small diameter portion 9b of the actuation pin 9 is again guided by the narrow width portion BCK of the guide hole 8, and the lever 7 swings, and when the first actuation pin 9 reaches one end of the guide fitting 6, the diameter The large portion 9a is inserted into the bulging hole portion 8b in the same manner as described above.
The hinged door 1 is placed in a locked state. For example, this position is 0
It is a degree position. When closing the hinged door 1, push the lever 7 by hand and push the large diameter portion 9a of the operating pin 9 into the bulging holes 8b, 8.
It is necessary to close the hinged door 1 from time to time in order to remove it from a.

As mentioned above, in conventional hinged doors, the open position regulating device is installed at the bottom of the hinged door, utilizing the gap between the hinged door and the window frame, and what is more, the open position regulating device prevents the locking state of the opening position regulating device. Since it was necessary to manually operate this open position restrictor to release the release, not only was this operation dangerous, but there was also a risk that the open position restrictor would get your hand caught when opening and closing the hinged door. This made it difficult to operate and dangerous, especially for children and the elderly. Furthermore, since the above-mentioned gap is set to be very narrow from the beginning, if the space between the floors becomes even narrower due to hanging of the hinged door 1, etc.

The opening position regulating device may rub against the window lower frame 2b, causing damage to the lower frame 2b, or in severe cases, the hinged door 1 may not open.

The present invention has been made in consideration of the above circumstances, and by attaching the above-mentioned opening position regulating device to the upper part of the window frame, it is possible to prevent the window frame from being damaged or the hinged door 1 not being able to open due to the hinged door sagging. At the same time, we have created a swing door opening/closing device that prevents this from happening, eliminates the risk of hands getting caught in the N release position setting tool when opening and closing the swing door, and also allows anyone to operate the door safely. The purpose is to provide

Next, the present invention will be explained with reference to FIGS. 3 to 6 showing an example of its implementation.

FIG. 4 shows a member corresponding to the open position regulating device 5 described above, and for convenience of explanation, elements corresponding to each of the constituent elements explained in FIGS. 1 and 2 will be explained here. are given the same reference numerals and their explanations will be omitted. However, as is clear from Figure 3.

In this embodiment, the open position restrictor 5 is attached using the gap between the window upper frame 2C and the upper stile 1C of the hinged door 1. Specifically, the lever 7 is attached to the window upper frame 2C via the mounting bracket 10, while the guide bracket 6 is attached to the upper frame IC'.
mounted on. When opening and closing a swinging door, one person does not touch the top of the swinging door 1 with their hands, so if the opening position regulating device 5 is attached to the top of the swinging door 1 as described above, the person's hand will be caught by this. There is no danger.Also, even if the 8-door door 1 sags, the gap between the upper stile IC of the hinged door 1 and the window upper frame 2C will not become narrower, so the opening position regulating device 5 will be held in this gap. This will not interfere with its opening/closing operation.

On the other hand, an operating lever 17 is attached to the center of the vertical stile 1d on the opening side of the hinged door IK. That is, this operating lever 17 is generally attached to a portion where a talent lock or the like is installed, and its details are shown in FIGS. 5 and 6.

In FIGS. 5 and 6, reference numeral 18 denotes a hollow mounting bracket that is screwed to the vertical frame 1d, and the rotating shaft 19 of the operating lever 17 is attached to this at a fixed angle, for example, 20 degrees in the forward and reverse directions. It can only be freely rotated within the range of . Further, a slide member 20 is arranged inside the vertical stile 1d so as to be able to slide up and down.

A connecting member 21 is fixed to the base end of the slide member 20 so as to be slidable in the vertical direction inside the mounting fitting 18 . Then, the rotation shaft 19 rotates forward and backward.

A pinion 23 fixed to the single rotation shaft 19 is engaged with a rack 22 fixed to the coupling member 21 so that the slide member 20 is caused to slide up and down via the coupling member 21 .

On the other hand, a guide member 25 is continuously provided on the vertical stile 1d and the upper stile IC of the hinged door 1, and this guide member 25
A rod rod 26 having flexibility is slidably installed inside. A connecting pin 27 is fitted into a predetermined position of the rod rod 26, and the connecting pin 27 passes through a vertically elongated hole 28 formed in the vertical frame 1d into a recessed notch in the slide member 20. 29 in a fitted manner. Furthermore, if the shaft 30 is placed outwardly on the rod rod 26 in the upper or lower part of the connecting bin 27, if the operating lever 17 is rotated 2θ degrees clockwise with the hinged door 1 closed, the shaft 30 will be moved to the cam. It is urged toward the indoor side along with the member 31, so that the packing abutment 33 around the swing door 1 is pressed against the packing 32 provided on the window frame 2 side.

Note that one set or two or more sets of the shaft 30 and the cam member 31 are provided as necessary.

Next, as shown in FIG. 4, a band-shaped actuating member 35 is disposed inside the guide fitting 6 of the open position regulating device 5. That is, this actuating member 351d has two raised portions 36a corresponding to the actuating pin 9 at two locations in its longitudinal direction.
, 36b, one end of which is led out from one end opening of the guide fitting 6.

It is connected to the rod rod 26. In this case, the two protrusions 36a, 36b are formed with the same spacing as the mutual spacing between the two protrusions 8a, 8b, and when the operating lever 17 is in the open position, K.

The two protuberances 36a, 36b each separate into two bulges 8a.

8b, K is configured so that its position is shifted when it is in the closed position.

Next, the operation will be explained. If you want to open the hinged door 1.

First, the operating lever 17 is rotated 2Q degrees counterclockwise. As a result, the slide member 20 moves downward by the functions of the pinion 23 and the rack 22, so the rod rod 26, which is engaged with the slide member 20 via the connecting pin 27, is guided by the guide member 25 and descends. At the same time, the shaft 30 also descends, and the shaft 30 or the cam member 31
be cut off from At this time, the raised portion 3 of the 1 actuating member 35
6a and 36b face the bulging holes 8a and 8b of the guide fitting 6, but since the operating pin 9 is located at the base end of the guide hole 8, it does not act on the operating pin 9. 17 to the closed position.

Next, push the operating lever 17 or the hinged door 1 outward to open it. In this case, as is clear from FIG. 2, when the opening angle of the hinged door 1 reaches Vj degrees, the large-diameter portion 9a of the operating pin 9 biases the spiral spring 13 in the bulging hole portion 8aK in the center of the guide hole 8. Inserted by.

It becomes locked. If you want to open the hinged door 1 further.

Set the operation lever 17 to the open position again, push the hinged door 1 slightly open, and then return it to the closed position.This operation causes the 1 operation member 35
One of the protrusions 36a presses the head of the actuating pin 27 fitted into the bulging hole 8a against the bias of the spiral spring 13, so that the large diameter portion 9a is removed from the bulging hole 8a. After being pulled out, the small diameter portion 9b is guided to the narrow portion, and the opening movement of the hinged door 1 is permitted.

The unlocking operation when the hinged door 1 is locked at the opening angle of 20 degrees is also performed in the same manner as above.

When closing the hinged door 1, the operating lever 17 is moved to the open position and pulled to its closing limit, and then moved to the closed position.

If you do this, as described above.

Since the shaft 30 follows the cam member 31, the packing 32
The gasket 33 is brought into pressure contact with the gasket, and the lock is made in a state where airtightness is maintained.

As described in detail above, according to the present invention, the open position regulating device is provided at the top of the swing door, and the locking state can be released by using the operating lever provided on the vertical stile of the swing door. There is no danger of hands being caught in the open position restrictor, and even children and the elderly can safely handle the device. In addition, since the operating lever is also used for locking, there is no need to separately provide a crescent. It has the advantage of maintaining the same appearance as a conventional swinging door and can be operated with one hand.
