[0001]

BACKGROUND OF THE INVENTION This invention is an intermediate locking device for sliding doors, which keeps sliding doors with a sliding structure open for a predetermined interval in order to ventilate the inside and outside of the building, and is safe from the viewpoint of crime prevention. Regarding

[0002]

2. Description of the Related Art Conventionally, when ventilating inside and outside buildings such as general houses, apartment houses, factories, etc., windows such as openings are opened, and mosquitoes, flies, etc. are protected by screen doors arranged in the openings. It prevents pests and other insects from entering the building interior from outside the building. The ventilation amount at this time is adjusted depending on the size of the opening range of the sliding door such as the window, and the ventilation is performed in a minute range by a slight opening, and the large ventilation amount is obtained by a full opening.

[0003]

[Problems to be Solved by the Invention] However, when adjusting the ventilation volume according to the size of the opening range of the sliding door, stop the opening range of the sliding door midway when setting the ventilation volume in the minute range. However, it is difficult to keep it fixed, and in the end, the sliding door is often completely closed or opened.

Also, when pets such as dogs and cats enter and exit through openings such as windows and entrances, or when they are stopped halfway so that they are not opened more than necessary, it is also possible to keep them fixed. It was difficult. Not only that, it is necessary to keep the windows etc. stopped halfway, unless you keep this firmly fixed, it will prevent intruders from the outside.
There are not enough protective measures, and there are many problems in terms of crime prevention.

Therefore, the present invention has been devised in view of various existing circumstances as described above, and when the sliding door is opened within a small range, it can be fixedly and firmly maintained, and the crime prevention It is an object of the present invention to provide an intermediate lock device for a sliding door, which is not only safe from the top, but also allows the opening range to be selectively adjusted and also has a sublock function.

[0006]

In order to achieve the above-mentioned object, according to the present invention, a pair of left and right sliding structures which are slid to the left and right to open and close the opening of a building structure. Is a lock device for stopping the sliding door of the sliding door while it is being opened. The rotating base is rotatably mounted on the inner surface of one of the sliding doors located on the outside, and the stopper lock that can be retracted and attached attached to this rotating base. Consists of and
It is characterized in that the stopper lock when retracted is retracted and stored on the back of the rotating base to make the sliding doors slidable, and the stopper lock when protruding is abutted on the end surface of the other sliding door located inside. And

[0007]

In the sliding door intermediate lock device according to the present invention, the left and right sliding doors are slidable with respect to each other when the stopper lock is retracted and retracted on the back surface of the rotating base.
On the contrary, when the stopper lock is projected, the stopper lock of one of the sliding doors abuts the center side end surface of the sliding door with respect to the other, and further sliding is restricted.

At this time, when the stopper lock is positioned on the center side of the opening by the rotation of the rotary base,
The opening range of the opening by the sliding door is reduced, and when the stopper lock is positioned on the end side of the opening by the rotation of the rotary base, the opening range of the opening by the sliding door is increased. Further, the pressing operation for advancing and retracting the stopper lock itself causes selection of adjustment setting of the opening interval of the sliding door or release thereof.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference numerals 1A and 1B shown in the drawings are sliding doors installed in an opening of a house or other building structure and sliding to the left and right so as to open and close the opening. The left and right sliding doors 1A and 1B are installed in a pair in the opening, and the locking device according to the present invention is installed on the inner surface of the outer sliding door 1A.

That is, one sliding door 1 located outside
A retractable stopper lock 3 is attached to a rotary base 2 rotatably mounted on the inner surface of A, and the stopper lock 3 when retracted is retracted and housed on the rear surface of the rotary base 1 so that the sliding doors 1A and 1B are reciprocated. Are slidable, and the stopper lock 3 at the time of protrusion is brought into contact with the end surface of the other sliding door 1B located inside.

Although not shown, the rotary base 2 is rotatably supported by, for example, a substantially cylindrical box-shaped opening fitted in a recess formed in the inner surface of the sliding door 1A. , On the inner surface of the sliding door 1A,
It is rotatably supported via a shaft on a shaft supporting portion having a cavity formed around it. In any case, the stopper lock 3 swivels on the back surface of the swivel base 2 as the swivel base 2 rotates, and a space for this swivel movement needs to be formed on the inner surface of the sliding door 1A.

Further, when the rotary base 2 is mounted on the inner surface of the sliding door 1A, care should be taken not to interfere with each other when the sliding door 1A slides with respect to the other sliding door 1B. It is necessary, and therefore, it is not preferable that the rotary base 2 is largely projected forward from the inner surface of the sliding door 1A. On the other hand, stopper lock 3
Is a so-called push-push lock, which has a self-recoverable structure that can be moved back and forth. When the head is pushed in the projecting state, it is immersed, and when the head is pushed in the projecting state, it is projected. Has a spring inside. Of course, when the stopper lock 3 is in the retracted state, like the rotating base 2, the mutual sliding doors 1
The slide operation of A and 1B is designed not to interfere.

As shown in FIG. 3, this stopper lock 3 is located at the center of the opening when viewed from the front when the left and right sliding doors 1A and 1B are in a closed state. When it is located at the end face on the side, it is assumed that it stops at a position slightly lower than the rotation center of the rotating base 2, and it is restricted in the direction of rotation only upward from that position, and the position of rotation at about 180 degrees It is set to stop at the end side position of the opening, which is the opposite side.

The stopper lock 3 may be retracted and retracted with respect to the surface of the rotary base 2 or may be retractable and retractable with respect to the rotary base 2, and the retractable structure may be selected arbitrarily. It is possible. Further, the locking device according to the present invention is not limited to the case where it is installed and set at the lower position of the inner side surface of the sliding door 1A as shown in the drawing, but the installation setting position such as the upper part or the central part is It can be changed arbitrarily.

Further, if necessary, a plurality of the lock devices of the present invention can be arranged in an array, and by doing so, the sliding door 1 can be stopped and maintained at any stage in the middle position of opening,
It is also possible to stop the rotation of the rotating base 1 at each stage within a rotation range of 180 degrees. Next, explaining an example of use of this, as shown in FIG. 1 and FIG.
The pair of sliding doors 1A and 1B that are pulled left and right are installed and set on the inner surface of the outer sliding door 1A. When the stopper lock 3 is retracted and retracted on the back surface of the rotating base 2, as in the conventional case, The sliding doors 1A and 1B can be slid on each other.

When the opening is slightly opened,
The stopper lock 3 may be in a protruding state at a position on the center side of the opening, and at this time, the other sliding door 1B or the sliding door 1A itself is largely opened by the stopper lock 3 contacting the center side end surface of the other sliding door 1B. It will not be done. Thus, when the stopper lock 3 is located on the center side of the opening, the stopper lock 3 itself is stopped at a position slightly lower than the center position of the rotating base 2, so that the other sliding door 1B Even if they come into contact with each other and stop, the position does not shift, and the predetermined opening interval is reliably maintained.

Further, when the stopper lock 3 is positioned on the end side of the opening by the rotation of the rotary base 2, the other sliding door 1B or the sliding door 1A itself can have a relatively large free space therebetween, and in the above-mentioned state. In comparison, the opening range of the opening can be made slightly larger. Such adjustment setting of the opening distance of the sliding doors 1A and 1B, or release of the stopping action by retracting and storing the stopper lock 3 on the back surface of the rotary base 2 are selected by the pressing action on the stopper lock 3 itself.

[0018]

The present invention is configured as described above, and therefore, when a sliding door such as an opening in a building structure is opened in a small range, it is in a slightly opened state at an intermediate position. However, this can be fixedly and firmly maintained. Further, the opened state at the middle position is safe in terms of crime prevention, because the protruding stopper locks lock the sliding doors without further opening them. Not only that, the opening range can be selectively adjusted by positioning the stopper lock by rotating the rotating base.

Moreover, the protruding stopper lock exerts a locking function of preventing the opened sliding door from being opened beyond its open position, and also enables a double locking state together with a locking for fixing the closed state of the sliding door. In order to do so, a sub lock function can also be obtained. Furthermore,
Adjustment setting of the opening interval of the sliding door or cancellation of the stop action by retracting and storing the stopper lock on the back of the rotating base can be selected by the pressing action on the stopper lock itself, and the pressing operation is extremely simple. Easy to handle.

Therefore, in addition to the adjustment of the ventilation amount inside and outside the building, various sliding doors can be fixedly maintained at a required slight intermediate position in the opening of the sliding door structure where pets and the like come in and out, which is excellent in practical use. Produce the effect.
