Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a lock for a door that pivots on the negative side and swings to open and close, or a lock for a shoji that pivots on both sides and swings to open and close.

As is well known, doors and doors that swing open and close around their pivots,
Alternatively, most of the locks installed in vertical rotating rooms or horizontal rotating windows have a lock box attached to the shoji stile, the needle bar moving outward and retracting when the handle is rotated, and a needle bar holder attached to the window frame. When the needle bar is in the protruding state, the shoji is closed so that it cannot be opened, and the needle bar in the protruding state is retracted by the handle, thereby making it possible to swing the shoji open and close. However, if the needle bar is forcibly retracted by the handle, there is no problem as long as the needle bar stays retracted until the shoji is closed and protrudes. The needle bar may protrude due to operation, etc. When the shoji is swung in the closing direction in this state, the nine-needle bar protrudes from the shoji stile and collides with the window frame, resulting in a major drawback of damaging the lock and the window frame.

Therefore, this invention was devised so that the lock body does not protrude outside the shoji stile when the shoji is open, and the lock body can only come in and out when the shoji is closed, and succeeded in overcoming the conventional drawbacks at once. This is what I did.

The lock of the present invention has the above-mentioned structure, and has a sliding rod (3).

A receiving part (2) is provided at the end of the outer box (2), and the front wall (2a
) is drilled with a through hole (A) that communicates with the receiving part (to), and the receiving part (
Since the lock is basically the same as a conventional lock except that a locking device (5) is provided between the lock (5) and the through hole, the operation and effect thereof will be omitted, and the locking device (5), which is a feature of the present invention, To explain only, when the shoji is open, the lock body (4) of the lock box (1) attached to the shoji HA (E)) is hand / l / (7
) is lowered into the outer box (2), and the lock (4) causes the sliding part (3) of the sliding rod (3) to reach the drilling position of the outer box through hole (), and the receiving part of the sliding part c32. The stopper member inserted into the outer box (2) is pressed in the protruding direction by the spring ring, and the protruding strip 6'0 of the horn protrudes into the through hole (2) of the outer box (2) and slides. The rod (3) is locked to the outer box (2) so as not to be able to reciprocate, and the sensor (2) is projected in the outer circumferential direction by the stopper ring. That is, the sliding rod (3), which reciprocates by the up-and-down swing of the lock body (4), moves from the sliding rod sliding part (end) to the outer box (
The handle (7) cannot be rotated to open or close at all when the shoji is open because it is immovable by the s and t flange (2) protruding into the through hole (a) of 2). When the shoji is closed from the open state, the locking device (5) that protrudes from the outside of the shoji stile first
The sensor so is connected to the window frame (the contact body (9
), the sensor is pushed in until the protrusion of ) is recessed into the outer box (2), and the protrusion of the stopper ring that protrudes to the through hole (A) is also pushed in by the protrusion of the sensor. It is pushed down into the outer box (2) and inserted into the receiving part ←) of the sliding rod part (2).

Release the lock between the outer box (2) and the sliding rod (3). When the stopper member is pushed down, it can be fitted into and removed from the protrusion Is on the sensor, so the sliding rod (3) into which the stopper ring is fitted will move according to the up and down rotation of the needle bar (4). Reciprocating movement is possible. In other words, only when the sensor (a) is pushed in and the stopper member is immersed into the outer box (2) by the sensor member, the reciprocating movement of the sliding rod (3) and the lock body (4) occur.
, which is capable of up-and-down swinging and rotation of the hand μ(7);
According to the reciprocating movement of the sliding rod (3), the stopper wheel that has come off may come off from the sensor (located at the receiving part (to) of the sliding part O), or the stopper ring that has come off may come off from the sensor (to). They fit together.

It should be noted that the specific implementation of the lock according to the present invention is not limited to the above-mentioned embodiments, but may be implemented using a locking device 2, for example, a locking device' (5).
) The same effect can be obtained by forming the concave groove of the stopper member constituting the stopper member and the protrusion of the stopper member that fits into it in the opposite way. (3) 1 tablet (4),
The specific shape and structure of the locking device (5) can be changed as appropriate without departing from the gist of the invention.

Therefore, in the lock of the present invention, the lock body can be undulated and swung only when the shoji is closed and the sensor of the locking device is pushed in. When the shoji is opened, the stopper of the locking device is pressed in the protruding direction by a spring, and the sensor moves out of the stopper. The sensor is pushed out in the outer circumferential direction while protruding into the through hole of the outer case, and the sliding rod, which reciprocates as the lock body slides up and down, is immovably locked to the outer case. As a result, the handle cannot be rotated when the shoji is in the open state, and the lock rod will never be able to stand up from its collapsed state, resulting in frequent collisions of the lock body with the window frame, resulting in damage and unpleasant collisions. You can eliminate the sound.

In addition, the locking device is automatically activated by opening and closing the shoji and operating the handle, so even if the lock is equipped with a locking device, there is no need for new operations and it can be used as usual. The structure is simple, and the lock of the present invention can be constructed simply by processing a conventional lock for attaching a locking device and incorporating the locking device, so it is easy to manufacture. This has a significant practical effect as a lock for a sash, which can damage window frames and the like if opened or closed in an uncontrolled state.
